  Citation × Citation Citation Abstract Copy Title: The Case for Age-Friendly Communities Author: Neal, Margaret, DeLaTorre, Alan Kenneth Year: 2016 The report was funded by Grantmakers In Aging, an organization dedicated to promoting and strengthening grantmaking for an aging society. The movement toward age-friendly communities is growing, with the key impetus being population aging. Beyond what individuals themselves can do to age optimally, the movement to create communities that are age friendly focuses on how the economic, physical, and social environments can be improved to address not only the needs but also maximize the assets of an aging population, for the benefit of all.

  Citation × Citation Citation Abstract Copy Title: Geometrical Modeling of Material Aging Author: Chudnovsky, Alexander, Preston, Serge Year: 1996 Material aging is understood as changes of material properties with time. The aging is usually observed as an improvement of some properties and a deterioration of others. For example an increase of rigidity and strength and reduction in toughness with time are commonly observed in engineering materials. In an attempt to model aging phenomena on a continuum (macroscopical) level one faces three major tasks. The first is to identify an adequate age parameter that represents, on a macroscopic scale, the micro and sub microscopical features, underlying the aging phenomena such as nucleation, growth and coalescence of microdefects, physico-chemical transformations etc. The age parameter should be considered as a parameter of state, in addition to the conventional parameters such as stress tensor and temperature. The second task consists of formulation of a constitutive equation of aging, i.e., equations of age parameter evolution expressed in terms of controlling factors, e.g., load and temperature. It is expected that at common circumstances a small variation of controlling factors results in a small variation of age parameter. However, at certain conditions, a sudden large variation of age parameter may result from a small perturbation of controlling factors. Experimental examination, classification and analysis of the condition that lead to such a catastrophic behavior, constitute the third task of the modeling. Formulation of local failure criteria within the scope of continuum mechanics is an example of this task. In many engineering materials the aging is manifested in variations of mass density as well as in the spectrum of relaxation time. Thus in a macroscopic test the aging can be detected in variations of intrinsic (material) length and time scales. Following this notion, in the present paper we employ the material metric tensor G as an age parameter. An evolution of Gin 4D -material space-time determines in our approach an inelastic behavior and time dependent material properties recorded by an external observer. The objective of the present work is to derive the constitutive equations of aging based on Extremal Action Principle. The variational approach seems to be most promising in view of complexity of the problem and lack of experimental data. It provides with a guide line for the experimental examination of the basic assumptions and modifications, if necessary.

  Citation × Citation Citation Abstract Copy Title: Employee Age Differences in Formal Performance Feedback Reactions: Examining the Effects of Perceived Valence, Content, and Delivery Author: Burlacu, Gabriela Year: 2011 As the nature of work is rapidly changing, organizations in developed nations all over the world are experiencing shifts in the age composition of their workforces. These changes, which include an aging workforce that is becoming increasingly age-diverse, indicate that organizational researchers and practitioners need to be better aware of how age differences manifest themselves in the workplace and what implications this has for effective employee management. In the current study it is proposed that employees of different ages react differently to various elements of a formal performance feedback event. Specifically, Carstensen's developmental Socio-emotional Selectivity Theory is used as a theoretical backing for explaining how and why employees of different ages perceive and react to performance feedback differently based on their perceptions of the valence, content quality, and delivery quality of the feedback. The results show evidence of age differences in feedback reactions, with younger adults being particularly concerned with information that will benefit them in the future and older adults being particularly concerned with information that conveys a positive relationship with one's supervisor. These findings have both conceptual and practical implications as we seek to build workplace aging theory and find ways to better manage and retain valuable employees of all ages in a changing world of work.

  Citation × Citation Citation Abstract Copy Title: Aging and the Semantic Differential: Semantic Stability in the Measurement of Social Evaluation Author: Petersen, Marilyn Diane Year: 1976 The purpose of this investigation was to assess the validity of utilizing the same semantic differential test as a measure of social evaluation for persons of different ages. The semantic differential, a rating technique by which judgments of stimuli are made on seven-interval bipolar descriptive continua called "scales", currently receives widespread usage as a measure of attitudes toward aging and the elderly. However, a lack of semantic stability across stimuli and across subjects, known, respectively, as "concept-scale" and "subject2 scale" interaction, has been found to occur with the technique in various areas of research. That such a lack of stability might occur across stimuli and/or subjects of different ages is suggested by the existence of . di fferences between people of different ages which affect both the appearance and functioning of the individual. These differences derive from the biological aging process, the life cycle process, and the social change process. This study investigated whether such cross-age differences are of sufficient severity to cause people of different ages to be perceived as different classes of stimuli and/or to perceive others as different populations of subjects. Ratings of eight videotaped stimulus models were made by 60 younger (aged 22 to 32) and 60 older (aged 60 and older ) volunteer subjects on a semantic differential test composed of 38 scales. The stimulus models, consisting of four younger and four older adults, were non-actors, unknown to the rating subjects, and presented for one minute in a standardized visual format and without sound. Of the 38 scales used, seven were selected as reference scales from earlier studies, 30 were suggested by a volunteer "generating" sample of 30 younger and JO older subjects, and one (young/old) was included as a check on the perceived ages of the stimulus models. Scale scores were factor analyzed to establish the underlying factor structure of social evaluation and to ascertain whether it rema1ned stable across stimulus model and subject age levels. Four separate factor analyses were performed -- younger stimulus models/younger subjects, younger stimulus models/older subjects, older stimulus J models/older subjects, and older stimulus models/younger subjects -- permitting comparisons between the factor matrices for concept-scale and subject-scale interaction. Three factors were defined by each of the four separate factor analyses of the scales. Factors A and B were found by two different methods of assessing factor similarity (inspection and coefficients of congruence) to be highly similar across both stimulus model and subject age levels; Factor C (a weakly defined factor) was found to be similar only for the older stimulus models across subject age levels. An examination of the scales heavily loaded on each factor for all relevant factor matrices resulted in the interpretation of Factors A, B, and C as reflecting Interpersonal Ability, Instrumental Ability, and Propriety, respectively. This study resulted in findings bearing upon three interrelated areas. First, the data suggest that: 1) older and younger adults constitute qualitatively approximately the same class of stimuli, and 2) older and younger adults constitute qualitatively approximately the same population of subjects. That is, perceptions were based on the same underlying dimensions of meaning regardless of age. Second, the data suggest that two major dimensions of social evaluation are Interpersonal Ability and Instrumental Ability. Comparisons of these two attitudinal dimensions with dimensions from other semantic differential studies revealed striking similarity. Third, the finding of stable scales and replicable dimensions suggests the appropriateness of constructing a cross-age semantic differential for social evaluation. Consequently, a 15-scale Cross-Age Semantic Differential for the measurement of social evaluation was proposed.

Research to date on age discrimination in selection has focused primarily on disparate treatment or intentional discrimination.

  Citation × Citation Citation Abstract Copy Title: Chronological Age, Mental Age and Socioeconomic Status Variance in Expressive Preposition Acquisition of Young Children Author: Heckel, Arthur J. Year: 1975 The present study was designed to determine the ages at which a sample of children between eighteen and forty-two months verbally and correctly express the fourteen prepositions known to be acquired by age four, using the Revised Expressive Preposition Test (REPT). The REPT was administered to sixty children chosen from day care centers and private homes within the metropolitan area of Portland, Oregon. Therewas no preference as to the sex, intelligence of the child or socio- economic status of the child's family. A statistical analysis was performed to determine the correlation between HEPT scores and the child's chronological age, mental age and the socioeconomic status of the child's family. Results show that expressive prepositions tend to be acquired at different age levels. Each age group tended to use a progressively greater number of the prepositions. None of the eighteen month olds used any of the prepositions. Only one-fourth of the twenty-four month olds used any of the prepositions. Half or more of the thirty month olds expressed the prepositions "under," "on," "in" and "up." Half or more of the thirty-six month olds expressed the prepositions "out of," "at," "in" and "up," but not "under" and "on." Half or more of the forty-two month olds expressed the prepositions "to, II, "out of," "under," "around," "at," "of," "with" and "up." One hundred per cent of the forty-two month olds also used the prepositions "in" and "on." The prepositions which were never expressed by 50 per cent of any of the children were "behind," "across," "off" and "by." A statistical analysis of the data revealed a moderate correlation between the children's REPT scores and their chronological ages (.68). Correlation coefficients indicated a high correlation between the children's REFT scores and their combined chronological and mental ages (.82). The children's SES scores did not correlate with REPT scores (1 per cent) when considered together with chronological and mental ages.

  Citation × Citation Citation Abstract Copy Title: The Mediating Effects of LMX on the Relationship Between Supervisor and Employee Age Differences, Satisfaction, and Retirement Intentions Author: Pytlovany, Amy Christine Year: 2016 Increasing age heterogeneity within organizations is pressing researchers to better understand the effects of a multigenerational workforce, teams, and dyads. In response to this, the present research aimed to investigate the effect of employee and supervisor age (in)congruence in relation to job and life satisfaction, as well as retirement intentions, all mediated by leader-member exchange (LMX), using a time-lagged design. Two different theoretical foundations were investigated. Based on the relational demography literature, better outcomes were expected to be associated with age similarity. Theories about implicit expectations relating age and social role guided hypotheses suggesting that beyond just similarity or difference, the direction of age differences would matter. Based on traditional social assumptions that age is associated with experience and wisdom, it was expected that work outcomes would be better when the supervisor was older than the employee, and worse when the supervisor was younger than the employee. Results did not support any of the proposed hypotheses, with the exception of the established relationship between LMX and job satisfaction. However, response surface graphs and polynomial regression results directed post hoc analyses which did reveal a main effect of supervisor age on LMX and an indirect effect of supervisor age on Time 2 job satisfaction through Time 1 LMX. Employees in this sample reported higher quality LMX when supervisors were younger, regardless of employee age, and in turn employees with younger supervisors reported higher job satisfaction. These results and the trends depicted by response surface graphs are discussed in relation to implications for research and practice. Title: The Mediating Effects of LMX on the Relationship Between Supervisor and Employee Age Differences, Satisfaction, and Retirement Intentions Author: Pytlovany, Amy Christine Year: 2016 Increasing age heterogeneity within organizations is pressing researchers to better understand the effects of a multigenerational workforce, teams, and dyads. In response to this, the present research aimed to investigate the effect of employee and supervisor age (in)congruence in relation to job and life satisfaction, as well as retirement intentions, all mediated by leader-member exchange (LMX), using a time-lagged design. Two different theoretical foundations were investigated. Based on the relational demography literature, better outcomes were expected to be associated with age similarity. Theories about implicit expectations relating age and social role guided hypotheses suggesting that beyond just similarity or difference, the direction of age differences would matter.

  Citation × Citation Citation Abstract Copy Title: Age Determination of Modern and Archaeological Chinook Salmon (Oncorhynchus tshawytcha) Using Vertebrae Author: Hofkamp, Anthony Raymond Year: 2015 Incremental growth rings in X-rays of salmon vertebrae have been used since the 1980s to age Pacific salmon (Oncorhynchus spp.) remains from archaeological sites in the Pacific Northwest. These age estimates, paired with generalized life history patterns, have been used to determine salmon species, season of capture and in turn season of site occupation. This approach relies on a variety of assumptions, the most fundamental of which is that rings represent true years. Archaeologists using vertebral age determination techniques have failed to adequately test this assumption and present their methodologies. This thesis assesses the validity of using incremental growth structures in Chinook salmon (Oncorhynchus tshawytscha) vertebrae to determine the age at death of fish represented in archaeological sites. This project develops criteria and a protocol for the identification of true annuli and tests these identifications on a collection of modern Chinook salmon of known age. Finally, this protocol is applied to archaeological remains of Chinook from Cathlapotle (45CL1). Three collections of modern known age fish (N=121) were used to evaluate and test approaches to aging Chinook salmon with vertebrae. These collections contained juvenile and adult Chinook from throughout Washington and Oregon. I evaluated a variety of methods for viewing rings including magnified surface images, X-ray images and thin sections to determine which is the most accurate, reliable and efficient, also considering the extent of specimen destruction. Rings visible in X-rays were found to reflect the internal structure of vertebrae rather than annular growth. The number of these internal walls did not correspond to the known ages of fish and are therefore not true annuli. Criteria previously described by salmon fisheries biologist were used to isolate annuli (on the centrum surface) on the Hanford reach collection (N=46). In a test for accuracy 39 (85%) were aged correctly. In a test of reliability utilizing five additional readers all but 14 cases showed discrepancies among readers. Results of the test of reliability were not as successful as other researchers in fisheries biology but given the high accuracy rate the method remains valid. The final goal of this project was to determine the feasibility of applying the surface ring method of age determination to archaeological collections. Archaeological salmon vertebrae from Cathlapotle (45CL1) on the lower Columbia River, Washington state were utilized. One hundred salmon vertebrae were selected and classified to species according to Huber et al. (2011); 89 were identified as Chinook. Of these, 39 had sufficient preservation of the surface to view and interpret incremental rings. Three ages were identified 3, 4 and 5 year olds. This ageing protocol can be applied to archaeological Chinook salmon vertebrae to estimate age of ancient Chinook salmon. Additional work is needed on other salmon species to demonstrate the methods validity across all salmonid species. This analysis has great potential for modeling salmon paleo-life history by contributing data from salmon populations prior to the major impacts of the 19th and 20th century. This is particularly valuable for salmon conservation because information on size, the timing and duration of freshwater emigration as well as the age of spawning and death is critical to the management of hatchery and wild salmon populations.

This study examined the role of age as a moderator in the relationship between job characteristics and two individual outcomes, job satisfaction and job tension. Specifically, the study focused on the relationship between social characteristics of the job (given social support, [received] social support, interdependence, interaction outside the organization, and feedback from others) and job tension and job satisfaction among Portland Water Bureau employees. Based in Socioemotional Selectivity (SES) theory (Carstensen, 1991), I hypothesized that these job characteristics would have a differential relationship with these outcomes for older and younger workers. Results showed that four of the eight hypothesized interactions were significant, providing support for age as a moderating variable. Differential interaction effects were demonstrated on job satisfaction and job tension. Further, this study incorporated a new conceptualization and measurement of the social support job characteristic (given social support), which demonstrated utility in predicting outcomes. Subjective age was also found to moderate the relationship between job satisfaction and job attitudes, but in a pattern similar to that found for chronological age. This study contributes to the existing literature by answering the call to examine the role of individual differences in the relationship between job design features and outcomes, and by increasing knowledge of the types of job characteristics that increase job satisfaction and reduce job tension for older and younger employees. Implications for the aging workforce are discussed along with future research to better understand the mediating mechanisms.

Much of this research has focused on the concept of conservation which was introduced by Piaget. It has generally been assumed that children under the age of five years are not capable of such conservation. Some recent evidence suggests that children Wlder this age do conserve on particular tasks. In this study one hundred children from age two years four months to three years seven months were tested for conservation of discontinuous and continuous quantity. Although some evidence of conservation in this age range was obtained, no consistent pattern emerged. An edible dough was used, so that both verbal (noneating) and nonverbal (eating) responses were recorded for children of these ages. A three-factor analysis of variance showed that there were no significant effects from age, eating/noneating, or continuous/discontinuous variables. However, there was a significant but puzzling interaction between the ccnt.inuous/discontinuous and eating/noneating factors.

Year: 2017 White rings visible on the centrum face of salmon vertebrae with X-rays have been used since the 1980s to age Pacific salmon (Oncorhynchus spp.), which in turn have been used to determine salmon species, season of capture and season of site occupation. This approach relies on a variety of assumptions, the most fundamental of which is that rings represent true years. Recent aDNA analysis has shown that the X-ray approach has flaws but the source of the error has been unknown. Given the value of reconstructing salmon population demographics and life history from ancient remains, establishing a valid and reliable method of ageing salmon vertebrae is extremely worthwhile. The main goal of our study was to evaluate if X-ray images of ring patterns on vertebrae provide a valid method of estimating fish age. Vertebrae from 66 adult Chinook salmon (O. tshawytscha) of known age were studied with X-rays, thin sections or low-powered (10–30 ×) magnification. We found that the white bands observed in X-rays are structural walls that do not grow annually. While X-rays are not a valid method for ageing salmonids, incremental growth seen on the surface of fish centra shows great promise for reconstructing ancient fish life history.

Over the next 30 years, the Portland-Vancouver metropolitan area will see dramatic growth in the proportion of the population that is aged 65 and older. Although the total population will increase by 47 percent, the 65+ population will more than double, growing by over 137 percent, to comprise 17 percent of the population in 2030, compared to 10.5 percent in 2000. Fueling this increase will be the aging of the baby boomers. As a city and a region, changes that will enhance the quality of life, independence, and well-being of our aging population can be made. These include addressing important needs that are identified, and taking advantage of assets and resources that an older and experienced population provides.

  Citation × Citation Citation Abstract Copy Title: Disengagement of older people in an urban setting Author: Somers, Melvina Year: 1977 This dissertation reevaluates the controversial Disengagement Theory of aging introduced by Elaine Cumming and William E. Henry in their book, Growing Old (1961), with particular emphasis on aging in the city. Disengagement theory embodies the antithesis to the traditional activity theory of aging based on a work ethic. Disengagement theory holds that normal aging is an inevitable mutual withdrawal or disengagement between the aging person and others in the social system, that it is universal, and that, by impl ication,it is a mutually satisfying condition since it results in a new equilibrium between society and the aging individual. The theory proposes that withdrawal happens automatically in the aging person because of ego changes which are "programmed" into the human organism. Activity theory, on the contrary, claims that maintaining physical, mental, or social activity is a prerequisite to successful aging. It implies that a meaningful social role is necessary to selfesteem, and that, allowing for biological impairments, the psychological needs of older people are not much different from those of middle-aged persons. Since the United States population aged 65 and over has a net annual increase of over 300,000 people, the questions as to whether they tend to be engaged or disengaged, and whether they should be integrated in or separated from the rest of society, become very important. According to the 1970 Census, over sixty percent of persons sixty-five and over live in metropolitan areas. Therefore their housing, transportation, medical care, and other needs have to be considered in urban policies. In planning services for older people it is imperative to know what kind of services are needed, and hence engagement or disengagement becomes a crucial question. It is the assumption in this research that the city and its older population have an investment in one another, and that the city is interested in the welfare of its older citizens. Theoretically, the study was guided by the principles of symbolic interactionism. Several methods were used in the approach to the research problem because it is believed that what is known as a "triangulated" perspective can come closest to revealing the various aspects of empirical reality. Specifically, the methods employed were the social survey, the depth interview, participant observation, unobtrusive observation, and the case study and life history technique. This research has used especially Weber's method of Verstehen or empathic unders tandi rig. Three hypotheses guided the research: Hypothesis One: Disengagement is not an intrinsic or inevitable phenomenon. If it occurs, it can be traced to various causes other than aging per se, such as ill health, personal misfortunes (such as widowhood), or social pressures (such as forced retirement). Hypthesis Two: Older people do not enjoy a disengaged state. There is continuity in personality and life style, and if older people choose nonengagement, it is a continuation of former habits. Hypothesis Three: A livable urban environment is a determinant in the life satisfaction of the aged. These hypotheses were tested empirically, using both qualitative and quantitative data; and our hypotheses have been confirmed by prevalence and recurrence of expected patterns in the behavior of our samples. The use of the inductive method has given consistent results in that no instances of intrinsic disengagement were discovered. We have been able to show that other causal factors were responsible for relative nonengagement if it occurred. The dissertation also reports many suggestions which were received on how the urban environment could be improved and how the city could help older people lead better lives.

  Citation × Citation Citation Abstract Copy Title: Supporting the Aging Workforce: The Impact of Psychosocial Workplace Characteristics on Employees' Work Ability Author: Rineer, Jennifer Rae Year: 2015 It is estimated that by 2020, 25% of the US labor force will be aged 55 or older. Along with this demographic shift, Americans and employees in other industrialized nations are now working longer than before, either out of preference or financial necessity. Therefore, it is essential that we understand how to support employees so that they can continue working in a healthy, happy, and productive manner as they age. The construct of work ability (the extent to which people perceive they can meet the mental and physical demands of their jobs) has the potential to guide research and practice on how best to support employees throughout the lifespan. However, though studied extensively in the occupational health literature, work ability has only recently gained attention in the Industrial/Organizational Psychology and Occupational Health Psychology literatures. This study helps to further integrate work ability into our field and theoretically ground the construct using the Job Demands-Resources model (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001). Specifically, this study examined psychosocial characteristics of the work environment (age diversity climate, team cohesion, organizational justice, and leader-member exchange) that were expected to buffer against the negative effects of increased age and poor health on work ability. The interaction between team cohesion and poor health had a significant effect on work ability. While the other hypothesized interaction relationships were unsupported, ancillary analyses showed that both team cohesion and age diversity climate do relate positively to work ability, even after controlling for age and health. These findings highlight the importance of a positive social work environment in supporting employees' work ability throughout the lifespan. Suggestions for future research include examining additional psychosocial predictors and behavioral outcomes of work ability, as well as conducting intervention studies aimed at increasing work ability by improving social aspects of the work environment.

Therefore, it is essential that we understand how to support employees so that they can continue working in a healthy, happy, and productive manner as they age. The construct of work ability (the extent to which people perceive they can meet the mental and physical demands of their jobs) has the potential to guide research and practice on how best to support employees throughout the lifespan. However, though studied extensively in the occupational health literature, work ability has only recently gained attention in the Industrial/Organizational Psychology and Occupational Health Psychology literatures. This study helps to further integrate work ability into our field and theoretically ground the construct using the Job Demands-Resources model (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001). Specifically, this study examined psychosocial characteristics of the work environment (age diversity climate, team cohesion, organizational justice, and leader-member exchange) that were expected to buffer against the negative effects of increased age and poor health on work ability. The interaction between team cohesion and poor health had a significant effect on work ability. While the other hypothesized interaction relationships were unsupported, ancillary analyses showed that both team cohesion and age diversity climate do relate positively to work ability, even after controlling for age and health. These findings highlight the importance of a positive social work environment in supporting employees' work ability throughout the lifespan. Suggestions for future research include examining additional psychosocial predictors and behavioral outcomes of work ability, as well as conducting intervention studies aimed at increasing work ability by improving social aspects of the work environment.

  Citation × Citation Citation Abstract Copy Title: The Prevalence of Rapid Weight Gain in Infancy Differs by the Growth Reference and Age Interval Used for Evaluation Author: Eckhardt, Cara L., Eng, Heather, Dills, John L., Wisner, Katherine L. Year: 2016 Background: Infant rapid weight gain (RWG) may predict subsequent obesity, but there are inconsistencies in the growth references and age intervals used for assessment. Methods: This study evaluated whether the prevalence of RWG (an increase of >0.67 in weight-for-age z-score) differed by growth reference (2006 WHO standards vs 2000 CDC references) and age interval of assessment (0–3, 0–6, 6–12 and 0–12 months). Pooled data from singleton term infants from two observational studies on maternal mood disorders during pregnancy were used (n = 161). Differences in RWG prevalence by growth reference and age interval were tested using Cochran’s Q and McNemar’s tests. Results: The CDC reference produced a higher RWG prevalence (14% of infants additionally categorized as RWG, p < 0.0001) within the 0–3 month age interval compared to the WHO standards; this pattern was reversed for the 6–12 and 0–12 month intervals. RWG prevalence did not differ across age interval within the WHO standards, but did differ with the CDC references (range: 22% for 0–3 months to 4.2% for 6–12 months, p < 0.0001). Conclusions: Caution is advised when comparing studies with different criteria for RWG. Future studies should use the 2006 WHO standards and a consistent age interval of evaluation.

The Initiative sought to gather information about older persons currently residing in Home Forward’s public housing properties, from persons age 55 and older on the waitlist for housing, and from older adults in the Portland area. While local data were unavailable at the time of this report, we know that nationally, more than one-third (37 percent) of the approximately 5 million households receiving housing assistance from HUD are headed by persons age 62 and older. With this in mind, Home Forward must make decisions now about how to respond to the aging of both current residents and the local community. The population of older persons has and will continue to increase in Multnomah County, and Oregon. While many older persons enjoy relative economic stability, a sizeable number are very poor and face housing instability and declining health. According to the 2010 U.S. Census, the poverty rate among county residents age 65 and older is 10.9%, higher than the national average of 9%. A recent study of Multnomah County adults with incomes at or below 200% of poverty level found that 44% of those who had moved in the prior five years had done so to reduce housing costs.

To date, there are no standardized norms on the development of fluency in children. Current investigations have contributed greatly to expectations of certain types and amounts of disfluencies in preschool-age children. Most of the research, however, has focused on observing children at discrete age levels from 2- to 7-years-of-age. Only one longitudinal study to date has been reported. Additional longitudinal data of preschoolaged children would benefit the establishment of normative data. Observing the same children over time helps to expose the subtleties that could be missed when looking only at specific age levels. The present study sought to contribute to the investigation of normal childhood disfluency by comparing various types and amounts of disf luencies in 44- to 49-month-old-children to the results of the same group of children when they were 30- to 35-months-of-age.

  Citation × Citation Citation Abstract Copy Title: Role exits among the aged Author: Mancini, Nancy Whitelaw Year: 1975 The concept of role exit presented by Zena Smith Blau in her book, Old Age in a Changing Society, refers to the ongoing process of relinquishing previously enacted social roles; a process which is part of everyday life for men and women of all ages. However, Blau argues that role exits in later life are different from those in earlier stages of the life cycle because they tend to be terminal and involuntary. These factors, according to Blau, cause role exits in old age to negatively influence the individual's overall satisfaction with life. This thesis examines the concept of role exit from three perspective: first, from a theoretical perspective as it emerges out of social role theory; second, in a substantive context as it relates to the problem of old age; and finally, from an empirical perspective as an indicator of reported life satisfaction among a sample of older adults.

  Citation × Citation Citation Abstract Copy Title: The Historical, Political, Social, and Individual Factors That Have Influenced the Development of Aging and Disability Resource Centers and Options Counseling Author: Elliott, Sheryl DeJoy Year: 2013 This thesis reports on the perspectives and experiences of policymakers, advocates, agency supervisors, and experts in the field of gerontology, about the development of Aging and Disability Resource Centers (ADRC) programs and Options Counseling (OC). By examining the foundations upon which ADRCs and OC are built, this study sought to inform future research about the effectiveness of existing practice, increase understanding of best practices, and clarify whether these emerging services are accomplishing original goals. ADRCs and OC intend to address long-term care issues and healthcare needs by providing a single entry point to the social service system. ADRCs offer information, assistance, and OC to people of all ages, incomes, and disabilities, and promote long-term care options that honor independence and respect for the needs and preferences of individuals, their families, and caregivers. They are the latest iteration of policymakers' efforts to provide affordable home-and community-based care for older persons and their caregivers. A total of fifteen qualitative interviews were conducted and analyzed using grounded theory methods. Key persons interviewed included experts in the area of aging, aging policy, and aging. Participants were recruited through referrals suggested by Portland State University's (PSU) Institute on Aging (IOA) staff. In addition, several key experts known to the researcher through affiliation with PSU's IOA agreed to be interviewed. Snowball sampling was then used to locate additional key experts. Interview participants were classified as advocates, state decision makers, policy makers, or academicians. Advocates included national and state directors of agencies that promote the development and management of effective services to aging adults. State decision makers included state directors, ADRC directors and supervisors, and program analysts. Policy makers interviewed were national program directors responsible for shaping the future of developing programs to assist older adults. Academicians who participated in the study have been instrumental in developing and researching practices that promote well-being for the aging and the aged. These key experts were selected based on their knowledge and ability to inform the strengths, weakness, and development of ADRCs and Options Counseling. Many have been instrumental in health and aging policy and service development and research, and possess insider knowledge not available to the general public regarding attitudes and interests motivating the actors. Findings indicate that ADRCs and OC are designed to manage within existing social service systems. They can benefit some individuals by providing more options and support in accessing public and private services. It remains to be seen whether they have the capacity to ameliorate some existing system-level problems. Findings highlight program strengths and weaknesses, sustainability issues, and policymakers, state decision makers', and providers' commitment to sustaining ADRCs and OC.

ADRCs and OC intend to address long-term care issues and healthcare needs by providing a single entry point to the social service system. ADRCs offer information, assistance, and OC to people of all ages, incomes, and disabilities, and promote long-term care options that honor independence and respect for the needs and preferences of individuals, their families, and caregivers. They are the latest iteration of policymakers' efforts to provide affordable home-and community-based care for older persons and their caregivers. A total of fifteen qualitative interviews were conducted and analyzed using grounded theory methods. Key persons interviewed included experts in the area of aging, aging policy, and aging. Participants were recruited through referrals suggested by Portland State University's (PSU) Institute on Aging (IOA) staff. In addition, several key experts known to the researcher through affiliation with PSU's IOA agreed to be interviewed. Snowball sampling was then used to locate additional key experts. Interview participants were classified as advocates, state decision makers, policy makers, or academicians. Advocates included national and state directors of agencies that promote the development and management of effective services to aging adults. State decision makers included state directors, ADRC directors and supervisors, and program analysts. Policy makers interviewed were national program directors responsible for shaping the future of developing programs to assist older adults. Academicians who participated in the study have been instrumental in developing and researching practices that promote well-being for the aging and the aged. These key experts were selected based on their knowledge and ability to inform the strengths, weakness, and development of ADRCs and Options Counseling. Many have been instrumental in health and aging policy and service development and research, and possess insider knowledge not available to the general public regarding attitudes and interests motivating the actors. Findings indicate that ADRCs and OC are designed to manage within existing social service systems. They can benefit some individuals by providing more options and support in accessing public and private services. It remains to be seen whether they have the capacity to ameliorate some existing system-level problems. Findings highlight program strengths and weaknesses, sustainability issues, and policymakers, state decision makers', and providers' commitment to sustaining ADRCs and OC. Close

  Citation × Citation Citation Abstract Copy Title: Ascorbic acid, lipid peroxidation, and aging Author: Leibovitz, Brian Evan Year: 1979 The role of ascorbic acid with regard to lipid peroxidation and aging has been examined. A thorough literature analysis indicates that free radical-induced lipid peroxidation is a plausible biochemical explanation for aging. Lipid peroxidation causes cellular damage due to altered enzyme activities, error-prone nucleic acid metabolism, and membrane dysfunction, as well as the accumulation of aging pigments in the lysomes. Ascorbic acid, a water soluble free radical quencher, was examined with regard to carbon tetra-chloride-induced lipid peroxidation and in vivo aging. Carbon tetrachloride, a well-known free radical inducer, caused marked increases in the ration of oxidized/reduced vitamin C only in the organs which metabolize carbon tetrachloride to the free radical form. Vitamin C treatment, 250 mg% in the drinking water, reduced the extent of carbon tetrachloride=induced lipid peroxidation. Aging is associated with marked increases in the ration of oxidized/reduced vitamin C in all organs examined with the exception of thymus. In organs exposed to high oxygen tensions, or in those exposed to high levels of free radicals, the ration of oxidized/reduced vitamin C exceeded the in vitro ration, indicating extensive lipid peroxidation. Vitamin C treatment reduced the extent of lipid peroxidation in vivo as determined by the ratio of oxidized/reduced vitamin C.

Allen, Meyer, Robert E., Messer, Lynne C., Luben, Thomas J. Year: 2014 A range of health effects, including adverse pregnancy outcomes, have been associated with exposure to ambient concentrations of particulate matter (PM) and ozone (O3). The objective of this study was to determine whether maternal exposure to fine particulate matter (PM2.5) and O3 during pregnancy is associated with the risk of term low birthweight and small for gestational age infants in both single and co-pollutant models. Term low birthweight and small for gestational age were determined using all birth certificates from North Carolina from 2003 to 2005. Ambient air concentrations of PM2.5 and O3 were predicted using a hierarchical Bayesian model of air pollution that combined modeled air pollution estimates from the EPA׳s Community Multi-Scale Air Quality (CMAQ) model with air monitor data measured by the EPA׳s Air Quality System. Binomial regression, adjusted for multiple potential confounders, was performed. In adjusted single-pollutant models for the third trimester, O3 concentration was positively associated with small for gestational age and term low birthweight births [risk ratios for an interquartile range increase in O3: 1.16 (95% CI 1.11, 1.22) for small for gestational age and 2.03 (95% CI 1.80, 2.30) for term low birthweight]; however, inverse or null associations were observed for PM2.5 [risk ratios for an interquartile range increase in PM2.5: 0.97 (95% CI 0.95, 0.99) for small for gestational age and 1.01 (95% CI 0.97, 1.06) for term low birthweight]. Findings were similar in co-pollutant models and linear models of birthweight. These results suggest that O3 concentrations in both urban and rural areas may be associated with an increased risk of term low birthweight and small for gestational age births.

  Citation × Citation Citation Abstract Copy Title: Growing old and going straight: examining the role of age in criminal career termination Author: Jolin, Annette I. Year: 1985 This study was designed to investigate mid-life desistance from crime as a function of general mid-life change. Adult developmental theory postulates that major occupational or lifestyle changes occur during mid-life, more so than during other developmental periods in adulthood. Such changes are said to occur in conjunction with specific transitional processes experienced by the middle-aged male. The abandonment of a criminal career at mid-life is viewed as a significant occupational and lifestyle change. It is examined in relation to the postulated transitional processes affecting aspects of the life areas of work and social relationships, as well as health and psychological well-being. Structured interviews were conducted with a small group of former career criminals and a small group of currently imprisoned middle-aged career offenders. Career offenders were compared with middle-age general population men, and former career offenders were compared with imprisoned career offenders. Limitations of the research design and the sampling methods are also discussed. The findings suggest that middle-aged career offenders, regardless of whether they have terminated their criminal careers or are still imprisoned, in large part resemble general population men in terms of mid-life concerns. A comparative analysis of ex-offender and inmate responses suggests that while the men resemble each other closely in the area of mid-life concerns, successful change away from a criminal career at mid-life means that mid-life developmental tasks must be accompanied by relatively well-developed social relationships and the ability to gain control of drug and alcohol problems.

  Citation × Citation Citation Abstract Copy Title: A study of Leslie model under stochastic environments Author: Shaukat, Kamran Year: 1981 The prediction and analysis of changes in the numbers of biological populations rest on mathematical formulations of demographic events (births and deaths) classified by the age of individuals. The development of demographic theory when birth and death rates vary statistically over time is the central theme of this work. A study of the standard Leslie model for the demographic dynamics of populations in variable environments is made. At each time interval a Leslie matrix of survival rates and fertilities of a population is chosen according to a Markov process and the population numbers in different age classes are computed. Analytical bounds are developed for the logarithmic growth rate and the age-structure of a population after long times. For a two dimensional case, it is shown analytically that a uniform distribution results for the age-structure if the survival rate from the first to the second age-class is a uniformly distributed random quantity with no serial auto correlation. Numerical studies are made which lead to similar conclusions when the survival rate obeys other distributions. It is found that the variance in the survival parameter is linearly related to the variance in the age structure. An efficient algorithm is developed for numerical simulations on a computer by considering a time sequence of births rather than whole populations. The algorithm is then applied to an example in three dimensions to calculate a sequence of births when the survival rate from the first to the second age-class is a random parameter. Numerical values for the logarithmic growth rate and the logarithmic variance for a population and the probability of extinction are obtained and then compared to the analytical results reported here and elsewhere.

Stand age has been implicated as a key factor in driving epiphytic species diversity and community composition. However, understanding the influence of substrate age, independent of the many confounding variables that affect live and dead wood substrates in a forest habitat, can be difficult. To test the hypothesis that substrate age has distinct effects on lichen community assembly independent of surface area, we sampled communities of calicioid lichens and fungi growing on wooden buildings that ranged from 2 to 82 years old. We found a total of 17 species, with a strong positive correlation between species richness and substrate age. We also tested the effects of surface area on species richness and found no relationship between the two variables. Our results indicate that substrate age influenced community composition; non-lichenized calicioid species acted as early colonizers and six calicioid species were recorded only on the oldest substrate. Old-growth associate species were found on substrates of varying ages, implying that additional variables may also be responsible for the colonization of old-growth associate species.

  Citation × Citation Citation Abstract Copy Title: An examination of disengagement among elderly people in a low income public housing facility Author: Bennion, Linda, Paradis, Marion, Petrie, Sheila Year: 1969 Six general hypotheses guided the development of the study: The older person experiences progressive disengagement from society resulting in feelings of isolation, depression, frustration, and despair; the aging person is dissatisfied with the degree of this process of social disengagement; the aging person gains satisfaction by participating in activities which lead to individual growth and/or benefit to others; the aging person lacks capacity and/or desire to participate in many activities or to continue the full-time roles of parent, job holder, and citizen; the aging person would like to choose his activities according to his desires and needs; and the aging person will more likely participate in activities if he is able to obtain adequate health care and has financial security. Descriptive and statistical inferential tests were used to analyze the data. A relatively small percentage of possible disengagement in the recreational, occupational, and family life areas occurred during the individual's life span from age 40 to age 70. The percentage of possible disengagement in these areas increased dramatically in the life span from age 70. Most of the respondents rejected loneliness and depression and felt in good spirits most of the time. A tendency toward less and less contact with others was seen. Statistically significant differences were found between activities which were presently enjoyed which were basically individual and passive in nature; and activities respondents would plan for themselves, which were of a significantly more social nature involving them in rewarding activity with others. Statistically significant differences were found between interest in the activity program available at Northwest Tower, basically recreation and entertainment; and the activities respondents would include in their program, mainly designed for self-enhancement or benefit to others. Statistically significant differences were also found between the number of activities available and the smaller number desired. The findings suggested that the preponderance of the respondents desired to withdraw from major responsibilities outside their household. Of those who desired responsibilities such as occupation, family or civic, they were prevented from assuming them most of the time because of their increasing age, deteriorating health, and lack of money. These were also the main factors operant in restricting their activity and preventing them from enjoying satisfactory ways of living. The majority of opinions as to society's responsibility to the aging suggested that intervention was necessary to provide financial security, health care, and better and cheaper methods of transportation. The findings of the study suggested the importance of more intensive research in planning programs directly related to meeting the individual needs of elderly people.

  Citation × Citation Citation Abstract Copy Title: Bus Replacement Modeling and the Impacts of Budget Constraints, Fleet Cost Variability, and Market Changes on Fleet Costs and Optimal Bus Replacement Age, A Case Study Author: Boudart, Jesse Alexander Year: 2011 Overwhelming evidence throughout the literature has shown that bus overhead and maintenance (O&M) costs increase as buses age. This has implications toward a fleet manager's decision of when one should buy, use, or sell buses to minimize total fleet costs. Unfortunately, there are uncertain market conditions associated with bus fleets that cloud the manager's ability to make appropriate decisions. Using integer programming (IP), O&M trends and changing market conditions are integrated into a model to better analyze bus fleets. Due to recent budget constraints of transit agencies, needs for a bus fleet replacement model have arisen. King County in Washington State has supplied cost aggregated data of their New Flyer (NF) and NF hybrid buses. These data have been analyzed to create statistical relationships based on rising O&M costs per mile with age, which are then integrated with the IP model to determine the impact of changing diesel prices, potential carbon dioxide (CO2) emissions costs, uncertain maintenance costs, and bus purchase cost subsidies. The goal is to aid fleet managers to determine the costs of early or delayed suboptimal bus replacement timing and the impacts of market variability on fleet costs and optimal replacement timing. The optimal replacement age for NF and NF hybrid buses based on King County data and current fuel prices of $3.99/gal are 16.7 and 18.3 years, respectively. It has been consistently observed that greater expense is incurred when buses are replaced earlier rather than later from optimal. To minimize total CO2 emissions (including operation and construction emissions), buses should be replaced slightly before the optimal replacement time without considering CO2 emissions. High diesel prices and CO2 emissions had little or no effect, on when buses should be replaced. However, higher maintenance costs reduced the optimal replacement time by almost two years. Although NF hybrid buses have been found to have no economic advantage over conventional buses, this finding may be a consequence of the different costs associated to the different routes operated by hybrid and conventional buses. Due to the lack of detailed King County's route level historical data, a study of the economic competitiveness of NF hybrids against conventional buses is outside the scope of this thesis. If buses are used less with age, the optimal replacement age is reduced. The optimal replacement age also dropped significantly when the Federal Transit Agency's procurement assistance is applied into the model. The procurement assistance can be up to 80% of the capital costs and can be considered a purchase subsidy from the transit agency viewpoint. If purchase subsidies decrease bus purchase prices by 1%, the optimal replacement age drops approximately 1.5%. When the bus purchase price is reduced by 80%, the optimal bus replacement age is less than 12 years, the FTA's minimum replacement age.

  Citation × Citation Citation Abstract Copy Title: Age, emotional maturity and the decision to marry Author: Duclos, Patricia Ann, Thomas, David F., Zusman, Joanne Year: 1971 The decision to marry and choice of mate are two issues contemplated by most individuals during their lifetime. It is our belief that the manner in which an individual makes these decisions is a reflection of that individual’s level of emotional maturity. In our society, the right to enter into a marriage agreement is largely determined by chronological age. Our research problem began with the hypothesis that there is no direct relationship between chronological age and emotional maturity at the time of marriage. For our study, marriages were divided into two general categories: 1) teenage marriages in which at least one partner was 20 years of age or younger, and 2) adult marriages in which one partner was Z1 years of age or older. The three independent variables studied were: age, sex of respondent, and sex of spouse. The dependent variable was emotional maturity. Emotional maturity was operationally defined by a questionnaire consisting of 67 statements about why people decide to marry, and why they chose their particular spouse. A panel of 12 experts in the field of marriage counseling were asked to rate each statement on a seven point scale of maturity-immaturity. The range and mode for each statement was computed and used to construct a new questionnaire consisting of 30 statements. Emotional maturity was defined by the absolute difference between the individual respondent’s rating and the expert’s modal response. A sample population was selected using recently married individuals who had applied for marriage licenses in Multnomah County, Oregon. The second questionnaire was mailed to the respondents. A 2 x 2 x 2 factorial design was used to identify which variable or combination of variables accounted for any discrepancy. A multiple regression analysis and a F test were run to test the hypothesis of the study. The data received supported the null hypothesis. However, there were several conceptual and methodological limitations to the study which raise questions as to the reliability of the measuring instrument and use of the concept of emotional maturity.

  Citation × Citation Citation Abstract Copy Title: Comparison of scores obtained on the PPVT and the PPVT-R Author: Choong, Jennie L.M. Year: 1981 The Peabody Picture Vocabulary Test (PPVT) is a widely used receptive vocabulary screening tool, but it is not without its limitations, such as inadvisable I.Q. usage and a standardization procedure that lacks scope. A revision of the PPVT, known as the Peabody Picture Vocabulary Test-Revised (PPVT-R) was published in 1981, and contains a more complete standardization procedure as well as some structural changes of the test itself (Dunn, 1981). Speech/language pathology, whose diagnosticians most commonly use the age equivalent value, is a profession that would gain from information which deals with the equivalency of the PPVT-R to the original PPVT. The purpose of the study was to compare age equivalent values obtained from the PPVT and the PPVT-R for a preschool aged population. Specifically, this study sought to discover whether or not significant differences existed between the age equivalent values derived from the PPVT and the PPVT-R. Eighty children, age three years, six months to four years, six months participated as subjects in the study, selected on the basis of their chronological age and enrollment in one of ten selected preschools. The subjects were divided into four groups (N=20), and each group was administered one form of the PPVT (A or B) and one form of the PPVT-R ( L or M). The resultant groupings were: I (A and L); II (A and M); III ( B and L); and IV ( B and M). Title: Comparison of scores obtained on the PPVT and the PPVT-R Author: Choong, Jennie L.M.

  Citation × Citation Citation Abstract Copy Title: Holocene Fluctuations of the Coe Glacier, Mount Hood, Oregon Author: Lillquist, Karl Douglas Year: 1988 Numerous moraines front the Coe Glacier on the north side of Mount Hood, Oregon. These moraines were identified and dated using a multiple methodology approach in order to establish a chronology for the advances and stillstands of the Cae Glacier. This chronology was compared to chronologies established for other glaciers on Mount Hood, North Sister, Mount Rainier and Mount Baker as well as glaciers in Scandinavia. The chronology was also compared to a long term temperature record from Longmire, Washington. The maximum identified extent of the pre-Little Ice Age Coe Glacier was indicated by moraines located at an elevation of about 1530 m and about 2 km downvalley of the present terminus. A general period of shrinkage of the pre-Little Ice Age Coe Glacier followed resulting in the deposition of moraines upvalley of the older pre-Little Ice Age moraines. The Little Ice Age Coe Glacier reached its maximum downvalley extent of about 1650 m elevation prior to 1731 AD. An earlier advance (1607 AD) was more extensive laterally than the 1731 AD advance. The Coe Glacier has been in a general state of recession since the mid to late 1700's. The prominent lateral moraines formed prior to 1882 AD. Four low moraines located within the Coe Glacier trough formed before 1901. Historical records indicate that the Coe Glacier has generally continued to recede since then. A comparison of the moraine ages and the historical activity of the Coe Glacier to other glaciers on Mount Hood as well as others in the Pacific Northwest and Scandinavia reveals that fluctuations of the glacier termini are generally synchronous. This similarity, combined with the similarity of the ages of Coe Glacier moraines to cool periods in a long term temperature record, indicates that hemispheric climatic patterns have played a major role in the past fluctuations of the Coe Glacier.

  Citation × Citation Citation Abstract Copy Title: Age, Intelligence, and Socioeconomic Status Variance in Preposition Acquisition by Children Author: Hustead, Georgie Year: 1974 Numerous linguistic studies have been done to substantiate the importance of prepositions in the English language. However, no normative studies have been done on the acquisition of expressing prepositions. The purpose of this investigation was to determine if there were demonstrable trends which would indicate a need for normative data on the acquisition of twenty-six prepositions tested on the Expressive Preposition Test (EPT). The study set out to determine at what age levels a given percentage of the prepositions were expressively acquired and if the socioeconomic status (SES) of the child’s family would be a determiner as to the age at which the child would expressively use prepositions. The EPT was administered to a total of thirty-six children between the ages of four and nine years. One-half of the children were from families of low SES and one-half were from families of high SES. The results show a high correlation between the age of the children and their ability to express prepositions. Each age group up through the eight-year-olds expressed a progressively higher percentage of the prepositions. A statement of positive correlation between intelligence-SES and EPT-SES was made in that those subjects in the high SES group scored higher on the intelligence quotient and EPT scores. Correlation coefficients indicate a slight correlation between the children’s intelligence quotient which ranged from 86-115 and their ability to express prepositions.

  Citation × Citation Citation Abstract Copy Title: Supervisor-Subordinate Directional Age Differences and Employee Reactions to Formal Performance Feedback: Examining Mediating and Moderating Mechanisms in a Chinese Sample Author: Burlacu, Gabriela Year: 2013 As a result of changing demographic trends in today's workforce, employees of all ages can now be found in all career stages. Consequently, the pairing of a younger supervisor with a relatively older employee is becoming increasingly more common. Research in the United States has shown that such demographically "non-normative" pairings have negative implications for employee attitudes and behaviors, and thus for employee performance management. However, little is known about the effects of such pairings in other nations and cultures, despite the fact that these demographic shifts are occurring on a global level. As such, this study examined the effects of these pairings on employee reactions to formal performance feedback episodes in a large organization in China, due to the nation's similarly shifting demographic trends and its economic power in today's global economy. A series of path analyses showed that being paired with a relatively younger supervisor did predict reduced employee feedback satisfaction and perceptions of feedback utility; but, contrary to the proposed model, these effects did not occur because of reduced interactional justice perceptions or reduced perceptions of leader-member exchange (LMX). Further, LMX did not moderate the study outcomes, demonstrating that having a better relationship with one's supervisor did not alleviate the effects of supervisor relative age on employee feedback reactions. The conceptual and practical implications of these results are discussed in light of a rapidly changing workforce, and of cultural differences, in China.

Society, however, has been slow to recognize this fact and has not accepted sexual activity among the aged. Along with the lack of social sanctioning, elderly persons are very susceptible to the myriad of myths, half-truths, misinformation, and incomplete data which affect their attitudes toward sexuality. Furthermore, older persons are susceptible to negative stereotypes of themselves as sexual beings. However, the effect of actual sexual activity upon overall life satisfaction among the aged has yet to be determined. Because there has been no empirical evidence concerning this, the degree of relationship between sexual activity and life satisfaction remains unknown. Since human beings remain sexual throughout life, and a large proportion of the elderly are institutionalized, this study will focus attention on the relationship between life satisfaction and sexuality among the institutionalized aged. It is important for social workers to explore these concepts, as empirically validated knowledge can be used as guidelines for professional values and practice.

  Citation × Citation Citation Abstract Copy Title: Effect of Mitochondrial Dysfunction on Age-Related Subcellular Damage & Autofluoresence in C. elegans Author: Mustain, Ashleigh R. Year: 2017 Despite considerable research, the patterns and causes of senescence (biological aging) and organismal death are still mysterious. Evidence has been presented that organismal death in the nematode C. elegans is accompanied by a burst of blue death fluorescence (DF), which is generated within intestinal cells by the necrotic cell death pathway [1]. This blue death fluorescence has overlapping activity with uranin fluorescence which can act as a marker for loss of membrane integrity in lysosome related organelles due to the fact it is quenched at low pH. It has been proposed that dequenching of uranin fluorescence upon gut granule permeabilization leads to a burst of green fluorescence in C. elegans [1]. This paper aims to investigate whether mitochondrial dysfunction, as represented by the gas-1 (fc21) gene mutation, leads to a different pattern of age related uranin fluorescence when compared to wildtype. In order to measure uranin fluorescence, a Leica confocal microscope was used to image age-synchronous samples of gas-1 compensatory recovery line worms as well as gas-1, progenitor, and N2 ,wildtype, worms dyed with fluorescein sodium salt at three different time points in their life cycle. Results should indicate whether there is a difference in age-related patterns of uranin fluorescence between the gas-1 lines as compared to wildtype. Using relative fitness data, inferences might also be able to be made regarding patterns of uranin fluorescence and fitness among the gas-1 compensatory recovery lines themselves.

S., Uggen, Christopher, Schnittker, Jason, Thompson, Melissa, Wakefield, Sara, Massoglia, Michael Year: 2017 The steep rise in U.S. criminal punishment in recent decades has spurred scholarship on the collateral consequences of imprisonment for individuals, families and communities. While several excellent studies have estimated the former prisoner population and the collateral consequences they face, far less is known about the size and scope of the total ex-felon population beyond prison walls, including those who serve their sentences on probation or in jail.

  Citation × Citation Citation Abstract Copy Title: The Effects of Ageism Climates and Core Self-Evaluations on Nurses' Turnover Intentions, Organizational Commitment, and Work Engagement Author: Cadiz, David Michael Year: 2010 It is estimated that by 2018, workers age 55 or older will compose nearly a quarter of the labor force (Tossi, 2009). The aging workforce is dramatically affecting the nursing workforce. Indeed, the nursing workforce is expected to face staffing shortages of epidemic proportions because of the impending retirement of nurses who are Baby Boomers (Buerhaus, et al., 2006). Moreover, the nursing shortage is exacerbated by younger nurses' greater willingness to turn over (Aiken et al., 2001). Consequently, investigating how the workplace context affects retention of nurses is important. The present study sought to address the nursing shortage concern through examining how the workplace climate associated with age-related worker treatment and individual characteristics affect nurse retention. In this study, I developed and validated new ageism climate measures, which include younger worker, older worker, and general ageism climates. I examined how ageism climates affect people's job withdrawal intentions, organizational commitment, and work engagement. Additionally, I investigated whether Core Self-Evaluation (CSE; Judge, Locke, Durham, 1998) moderates the ageism climates relationships with the outcome variables. During the scale development and validation process, I found that assessments of younger and older worker ageism climates depend on the age of the respondent, whereas general ageism climate did not have this dependency. Because younger and older ageism climates displayed measurement non-equivalence across age groups, I tested each of my hypotheses using three sample variations (under 40, 40 and older, and combined sample). In the under 40 sample, CSE buffered the negative effects of negative older and younger worker ageism climates, and CSE enhanced the positive effects of a positive general age climate on turnover intentions and organizational commitment. In the 40 and older sample, I found that less ageist younger and older worker climates were associated with decreased turnover intentions and increased affective commitment. Finally, in the combined sample, I observed that a less ageist general ageism climate was associated with lower turnover intentions and greater affective commitment. The results contribute to our understanding of how perceptions of age-related treatment affect important workplace outcomes. The findings also support ageism climates as separate measures. However, additional measure development and validation is needed because this was the initial study to investigate ageism climate. This study has implications for the relational demography paradigm (Tsui & O'Reilly, 1989) in that people's age group identification may affect their ageism climate perceptions. This potentially explains the differential relationships among the ageism climates on the outcomes between the under 40 and 40 and older age groups. From a practical perspective, improving ageism climates in the workplace could positively affect nurse retention, which could alleviate some of the nursing shortage concerns.

  Citation × Citation Citation Abstract Copy Title: Sustainable, Affordable Housing for Older Adults: A Case Study of Factors that Affect Development in Portland, Oregon Author: DeLaTorre, Alan Kenneth Year: 2013 Portland, Oregon, is considered to be a leader in sustainable development. Government agencies, nonprofit organizations, and businesses have been innovators in policymaking and practice that is aimed at creating a more sustainable city. Despite population aging, little is known about how or whether planners and developers consider older persons in terms of sustainable development. Thus, this study examined the case of sustainable, affordable housing developed for low-income adults aged 55 and older. Interviews with 31 key informants were conducted in order to answer three research questions: What is the meaning of sustainable development in Portland, Oregon, as it pertains to affordable housing for an aging society? How and why has sustainable, affordable housing for older adults been developed in Portland? What are the policies that affect the availability and appropriateness of sustainable, affordable housing for older adults in Portland? The sample included individuals who influenced the creation of senior housing (e.g., urban planners, architects, nonprofit directors) and who were identified either because of their roles within local housing development or through snowball sampling. Six Portland-area developments provided the context for studying how and why sustainable, affordable housing for older adults was planned and created in the city. The findings suggested that introducing the topic of aging into the discourse of sustainable development will lead to a more robust meaning of the concept, which can aid future research, policy, and practice. Five elements characterizing sustainable housing for older adults were identified: physical accessibility; proximity to community services; infrastructure that connects housing with services; healthy living environments; and high-quality social spaces in and near housing developments. The findings also pointed to the need for sustainable development practices to pay attention to social equity and the equitable distribution of affordable housing, including housing for older adults. Several insights into how sustainable, affordable housing for older adults developed in Portland were gained (e.g., using government subsidies; involving aging experts in integrated design processes; intersectoral partnerships that led to the city becoming an early adopter in greening its affordable housing), as well as why such housing was completed (e.g., there was a collective public-sector response to meet the need for creating sustainable, affordable housing; an emerging culture of sustainable development in Portland; urban and regional planning efforts have begun to address population aging). However, the amount of sustainable, affordable housing remains insufficient to meet Portland's aging population. Reasons identified include: the absence of specific housing policy attuned to the needs of older adults in Portland; disconnects between housing and health care and supportive services; and lack of integration of older adults in the planning, design, and development processes. Room for innovation and improvement exists in regard to healthy, accessible, green, and affordable housing policies and the development of new models of housing for an aging population. Based on this research, 10 guiding principles of sustainable development for an aging society were proposed to inform future research, as well as planning and development efforts.

  Citation × Citation Citation Abstract Copy Title: Population Determinants of Social Change: An Analysis of the Age composition of the United States from 1920 to 1983 Author: Burkhardt, Guy Norman Year: 1988 The purpose of this study is to explain the consequences of a changing age structure on social change in the urban industrialized environment. This analysis determines the impact of the younger to the older labor force aged population on both negative and positive forms of social change behavior. The indices of social behavior to be examined are the deviant behaviors of homicide, suicide and certain innovative behavior associated with patent activity. The specific age composition of the population to be examined is the ratio of young male adults aged 15-34 to those aged 35-64. The analysis of main effects of the model is conducted, controlling for the effects of unemployment and urban growth. These control variables have traditionally been documented as being important factors associated with deviant forms of behavior. However, the more contemporary literature increasingly recognizes the relationship between age and the tendency to act out certain social change behaviors. Most of social change emphasizes "negative" deviant behaviors. This study incorporated two innovative measures related to patents in an attempt to measure "positive" forms of deviant behavior. This strategy is used to determine if positive behavior can be explained by the same independent variables used to account for negative behavior. A multiple linear regression model is used to analyze the hypothesis of the research model. The results show a significant relationship between the age composition of the population and the selected indices of social behavior. As expected, the traditional indices of negative deviant behavior are consistent with the findings of the model. The less traditional indices used to measure innovation also result in positive findings. However, the significance of these latter findings is more modest in comparison to those of the traditional measures of deviant behavior. The implications of this study are that when pressure for opportunity builds in the population due to a heavy proportion of young adults, the prevalence of both positive (innovative) and negative (destructive) behavior increases. These behaviors reflect the need within society to change and adapt to population requirements. These dynamics are heightened as our society becomes more urbanized under the circumstances. The task for social policy makers is how to encourage the positive innovative forms of social change.

  Citation × Citation Citation Abstract Copy Title: An investigation of the development of the phonemes /t/and /k/ in the speech of preschool children. Author: Weybright, Glenn Douglas Year: 1974 Research regarding children's instrumental articulation development has provided the speech clinician with schedules of speech sound development. These developmental tables list ages when specific phonemes are mastered by normal children. Such schedules tend to give the impression that certain sounds must be developed before others can occur. Menyuk (1972) has expressed a similar point of view regarding phonemes /t/ and /k/. She has hypothesized: that phoneme /t/ must develop before phoneme /k/; and that sound element initial /t/ is mastered at an earlier age than initial /k/. The present investigation was designed to operationally test the validity of Menyuk's observations. The primary purpose of this study was to determine the ages at which phonemes /t/ and /k/ are mastered by normally developing children, thereby obtaining the order in which these phonemes are learned. A secondary purpose was to present an alternative to the concept of mastery of speech sounds by determining the ages at which children acquire phonemes /t/ and /k/. Four specific questions were posed by this study: Is phoneme /t/ mastered before phoneme /k/? Is sound element initial [t} mastered before initial [k]? What is the order of mastery of the remaining two sound elements of each phoneme? What is the order of acquisition of the two phonemes?

Year: 1998 This paper proposes that the aging baby boom will contribute significantly to transportation problems in the future because 1) current land use patterns necessitate dependence on cars; and 2) aging baby boom women will drive more than elderly women do now. Policies that promote central city residence by stressing the transportation advantages of high-density living, therefore, should have particular appeal to baby boom women seeking prolonged independence. Such policies would also serve the interests of localities by reducing traffic congestion, pollution, and further sprawl. We suggest that a combination of direct and indirect housing policies comparable to those that financed suburbanization fifty years ago (i.e. urban renewal, highway construction, and veterans' benefits) could be implemented over the next twenty years to recentralize population by addressing the transportation needs of aging baby boomers.

Religious traditions play an integral role in any society and have a profound and systemic effect on many other aspects of culture, and should therefore be of great interest to archaeologists. However, belief systems might not be well-represented by material culture. In order to potentially understand the relationship between Iron Age Irish economy and religion, in this case as it pertains to cattle, it is necessary to make use of evidence from a variety of disciplines: Classical texts referencing Celtic culture, early historical Irish law tracts and mythologies, and archaeological evidence from known pre- Christian ritual sites.

  Citation × Citation Citation Abstract Copy Title: Local government and manpower programs for the disadvantaged: an evaluation of the Portland Concentrated Employment Program Author: Copperman, Lois Farrer Year: 1976 Manpower programs for the disadvantaged have been operated in the United States for approximately fifteen years. The programs - introduced under the authority of the Manpower Development and Training Act of 1961, the Economic Opportunity Act of 1964, the 1967 amendments to the Social Security Act, and the Comprehensive Training and Employment Act of 1973 - were all concerned with the employment and earning of certain groups. This body of legislation was intended to intervene in particular sectors of the labor market having a deferentially high unemployment rate, not offset by higher wages and other benefits. The intent was to reduce labor market immobility due to geographical location, lack of skills, and age, sex or color discrimination. The ultimate objective of the manpower programs was to improve the employment and earnings experience of the disadvantaged target population. Little is presently known about the impact of the programs on the earnings and employment of participants after they leave the program. This retrospective study attempts to determine the impact of the Portland Concentrated Employment Program (PCEP) on the post-training incomes of 1985 PCEP participants and a control group of 1150 individuals applying to or enrolled in the peEP between 1968 and 1972. The control group is a group of persons who are statistically equivalent to the participants as far as demographic variables and their application to and eligibility for the PCEP; but, who for some unknown reason, did not enter the program. Follow-up income information was purchased from the U.S. Social Security Administration in coded cells containing five or more individuals. The five digit numeric code classified individuals by participation or nonparticipation in the PCEP, sex, race, age, and education. The Analysis of Variance statistical technique was utilized in analyzing the 1973 mean earnings of the code groups included in the study. The analysis of the data resulted in the following major findings. Of the five independent variables - participation, sex, race, age, and education - there were significant interactions between participation, race, and age; participation and race; and sex and age. The first interaction is a result of Black participants and the White control group earning their highest incomes between the ages of 21-25 years. White participants and the Black control group had generally rising incomes as age increased up to 45 years. All groups 45 years and over earned low incomes relative to other groups in the study. The interaction between participation and race resulted from the Black control group in most cases earning more than all other groups in the study. Black participants earned slightly more than White participants. But, the White participant group appears to have benefitted more from participation in the PCEP, in comparison with the White control group, than did Black participants. Enrollment in the PCEP in most cases did not raise the incomes of participants significantly higher than the incomes of the control group. Sex and age demonstrated a significant interaction which was primarily due to the poor performance of males ages 45 and over. In all other age groups males earned significantly more than females. The groups with a high school degree and under 45 years of age earned significantly more than those without a high school degree. The education group benefiting most from participation in the PCEP included persons with 1-9 years of education. Over seventy percent of the persons included in this study in both the participant and the control groups earned incomes below the official 1973 poverty level. Participation in the PCEP did not raise the mean earnings of groups studied above the poverty level. Considering income alone, approximately thirteen percent of the participants in comparison with their control groups are considered to have benefited significantly from the PCEP. Six percent of the participants may have gained more benefit from continued labor market participation than from enrollment in the PCEP. The findings of this study indicate that the benefits to participants in the PCEP were not as substantial as expected. Title: Local government and manpower programs for the disadvantaged: an evaluation of the Portland Concentrated Employment Program Author: Copperman, Lois Farrer Year: 1976 Manpower programs for the disadvantaged have been operated in the United States for approximately fifteen years. The programs - introduced under the authority of the Manpower Development and Training Act of 1961, the Economic Opportunity Act of 1964, the 1967 amendments to the Social Security Act, and the Comprehensive Training and Employment Act of 1973 - were all concerned with the employment and earning of certain groups. This body of legislation was intended to intervene in particular sectors of the labor market having a deferentially high unemployment rate, not offset by higher wages and other benefits. The intent was to reduce labor market immobility due to geographical location, lack of skills, and age, sex or color discrimination. The ultimate objective of the manpower programs was to improve the employment and earnings experience of the disadvantaged target population. Little is presently known about the impact of the programs on the earnings and employment of participants after they leave the program. This retrospective study attempts to determine the impact of the Portland Concentrated Employment Program (PCEP) on the post-training incomes of 1985 PCEP participants and a control group of 1150 individuals applying to or enrolled in the peEP between 1968 and 1972. The control group is a group of persons who are statistically equivalent to the participants as far as demographic variables and their application to and eligibility for the PCEP; but, who for some unknown reason, did not enter the program. Follow-up income information was purchased from the U.S. Social Security Administration in coded cells containing five or more individuals. The five digit numeric code classified individuals by participation or nonparticipation in the PCEP, sex, race, age, and education. The Analysis of Variance statistical technique was utilized in analyzing the 1973 mean earnings of the code groups included in the study. The analysis of the data resulted in the following major findings. Of the five independent variables - participation, sex, race, age, and education - there were significant interactions between participation, race, and age; participation and race; and sex and age. The first interaction is a result of Black participants and the White control group earning their highest incomes between the ages of 21-25 years. White participants and the Black control group had generally rising incomes as age increased up to 45 years. All groups 45 years and over earned low incomes relative to other groups in the study. The interaction between participation and race resulted from the Black control group in most cases earning more than all other groups in the study. Black participants earned slightly more than White participants. But, the White participant group appears to have benefitted more from participation in the PCEP, in comparison with the White control group, than did Black participants.

Year: 2016 Background: CogState is a computerized cognitive battery spanning domains of memory, executive function, and speed and processing. CogState, designed to be robust to education level and efficient for repeated administration with minimal practice effects, holds potential for detecting early cognitive deficits that may prove to be due to preclinical Alzheimer’s disease (AD). This project aimed to provide convergent and construct validity for CogState in detecting preclinical AD during late-middle-age. Methods: 279 late-middle-aged participants from the Wisconsin Registry for Alzheimer’s Prevention (mean age 63±7 years; 69% female; 37% APOE4+) completed a traditional paper-based neuropsychological battery and a CogState battery consisting of seven tests approximately six years post-baseline. A composite cognitive impairment score (CCI) was calculated using eight neuropsychological tests acquired longitudinally and was estimated at age 50 to remove confounding age effects; higher CCI indicates lower cognitive performance. Mild Cognitive Impairment (MCI) status (n=36) was determined by consensus using clinical and/or pyschometric criteria. A subset underwent cerebrospinal fluid (CSF) collection (n=36) and PET-PiB imaging (n=46). To determine clinical relevance of CogState, MCI and normal controls were compared by ANCOVA on select CogState variables controlling for age, literacy, gender, APOE4, AD family history, self-rated computer familiarity, and depression. To determine whether biomarkers (CSF Aβ42/Aβ40, CSF total-tau/Aβ42, global PiB burden) or CCI predict CogState performance, we ran multiple regression models controlling for age, sex, literacy, and computer familiarity. Results: MCI participants performed significantly worse (p Conclusions: MCI status, biomarkers for amyloid and tau, and CCI all predict performance on the CogState variables assessed in this study of late-middle-aged adults. CogState performance at a single time point may be an important indicator of preclinical AD processes.

Its importance has been emphasized by Van Riper (1954), Westlake and Rutherford (1961), Boone (1971), and other authors. A review of the literature revealed three trials of sustained phonation have been utilized by most researchers to determine maximum duration of phonation. Additionally, the review revealed a lack of test-retest reliability in maximum phonation time in children. The present study was designed to determine the variability in test-retest of maximum duration of· sustained /a/ among prepubescent male and female children. Eighty subjects, twenty at each of the four age levels, seven, eight, nine and ten, were selected from a larger pool using a random order table. Each age level was further divided into two groups of ten male and ten female subjects. A tape recording of twenty maximum phonations of /a/. was obtained for each subject. A second measure of maximum phonation time was recorded between two weeks and a month following the original run. The essential questions of this investigation were: 1. Given the means of age and sex groups of the longest performance of maximum duration of sustained /a/, is there a significant difference between runs one and two? 2. In the test cohort does the rank order of maximum phonation time differ between runs one and two? The following secondary questions were also posed: 1. Is there a significantly greater duration of the longest sustained /a/ when given twenty trials as opposed to the first three trials? 2. Is there a relationship between sex and the duration of sustained /a/? 3. Given four prepubescent age groups, is age a factor in relation to length of phonation?

Subjects used 10 semantic differential scales to rate six artificial brand names that targeted five phonemes. Subjects also described the potential products they imagined these artificial brand names to represent. Quantitative analysis alone provided insufficient evidence to conclude that age or gender affect sound symbolism in American English. While 26 out of 60 scales showed a monotonic shift among the means of the three age groups, only three were statistically significant. The evidence of differences between genders was similarly weak; only five scales out of 60 showed a statistically significant difference when comparing genders. Analysis of the qualitative data, however, suggested both monotonic generational shifts as well as generational blips in sound-symbolic associations. Of particular interest is the possible influence of pop culture, fashions, and fads, and society's shifting focus from broadcast to narrowcast media. The implications of this research are relevant for both theory (empirical evidence for iconicity in language) and application (e.g., devising brand names that communicate particular attributes to specific demographics).

Twenty-seven subjects, ranging in age from sixty-four to eighty-three years of age (54 ears) were ultimately chosen as subjects. A young adult group, ranging in age from eighteen to thirty years of age, with normal audiometric hearing levels served as controls. Reflex threshold levels were obtained using 500 Hz., 1000 Hz., and 2000 Hz. pure tones and noise stimuli. Assessment of hearing loss was calculated on the difference between measures to ascertain hearing loss category and slope of loss according to a formula developed by Jerger (1974). The following conclusions were made on the basis of data collected in this investigation: The SPAR test was significant in assessing hearing sensitivity levels among the sample of geriatric subjects. The SPAR test was not statistically significant in assessing slope of loss in this sample of geriatric subjects. Reflex thresholds were consistently higher for aging than for a sample of young adults with normal hearing. This was true even among elderly subjects with average pure tone thresholds in the normal range. A significant portion of this carefully screened older adult sample displayed abnormal middle-ear function (as measured by tympanometry) in the absence of conventional audiometric indications of this. A significant portion of this older adult sample provided audiometric evidence of middle-ear pathology.

  Citation × Citation Citation Abstract Copy Title: Performance of adolescent autistic males on the Michigan picture language inventory Author: Kline, Marcia Sharril Year: 1975 The purpose of this study was to compare the expressive and comprehensive language structure skills of a selected sample of normal males and adolescent autistic males, using the Michigan Picture Language Inventory (MPLI) as the investigating instrument in order to determine if a statistically significant difference existed between the two groups. The autistic and normal subjects were matched for mental age scores within plus or minus two months as measured by the Peabody Picture Vocabulary Test (PPVT), Form B. Seven autistic male and seven normal male subjects were selected from the greater Portland metropolitan area to be included in this study. Variables controlled were chronological ages of the autistic males and the mental age scores of the normal subjects. The autistic males were matched for mental age scores as measured by the PPVT (Form B). The results of this study revealed no statistically significant differences between the performance of the autistic and normal subjects relative to the overall expression and comprehension language structure skills. An analysis of the nine word classes indicated that the autistic subjects performed significantly better than the normals on the expressive personal pronouns and the expressive adjectives. In addition, a statistically significant difference was found between the experimental and control subjects on the comprehension of singular and plural nouns with the autistic males performing better. The findings of this investigation indicate that most of the autistic subjects obtained scores which were relatively close to their matched normals; however it should be noted that there was a considerable chronological age difference between the autistics and their matched normals. The “intact auditory memory” and the familiarity with this type of testing procedure may account for the lack of statistically significant difference in overall expression and comprehension scores. The poorer performance of the autistics on pronoun items is in agreement with many researchers who have studied autistic language and stated that the autistic child may lack the rule for correct pronoun assignments and may “echo” what is heard. The better performance of the autistic subjects on the comprehension of singular and plural nouns, as well as the poorer performance on personal pronouns and adjectives could possibly be explained by the proficient use of concrete versus abstract language.

Year: 2017 Understanding survival of precocial chicks in the period immediately following hatching has important conservation implications because population growth is often sensitive to post-hatching survival. We studied federally threatened Western Snowy Plover (Charadrius nivosus nivosus) broods at the northern limit of their range in coastal Oregon (n ¼ 1,157) and Washington (n ¼ 84) from 1991 to 2011 in an attempt to understand seasonal, annual, and spatial patterns of chick survival. In Oregon, plover chick survival increased with age, varied between sites, and was greater at sites with predator management. The mean probability of surviving from hatch to fledging at 28 days of age in Oregon was 0.57 (95% CI: 0.50, 0.63). In Washington, where predator management was not employed, we conducted separate analyses using individually banded and unbanded chicks and results indicated that survival generally increased with chick age. The mean estimated probability of surviving from hatch to fledging at 28 days of age in Washington was 0.27 (95% CI: 0.20, 0.35) for individually banded chicks when perfect detection was assumed. This probability increased to 0.67 (95% CI: 0.41, 0.83) when we analyzed unbanded chicks and included detection probability. Our findings confirm the importance of considering age effects in the survival of Snowy Plover chicks and raise questions about the validity of assuming perfect detection of plover chicks during brood checks. This work also highlights the benefit of predator management on chick survival.

In Oregon, plover chick survival increased with age, varied between sites, and was greater at sites with predator management. The mean probability of surviving from hatch to fledging at 28 days of age in Oregon was 0.57 (95% CI: 0.50, 0.63). In Washington, where predator management was not employed, we conducted separate analyses using individually banded and unbanded chicks and results indicated that survival generally increased with chick age. The mean estimated probability of surviving from hatch to fledging at 28 days of age in Washington was 0.27 (95% CI: 0.20, 0.35) for individually banded chicks when perfect detection was assumed. This probability increased to 0.67 (95% CI: 0.41, 0.83) when we analyzed unbanded chicks and included detection probability. Our findings confirm the importance of considering age effects in the survival of Snowy Plover chicks and raise questions about the validity of assuming perfect detection of plover chicks during brood checks. This work also highlights the benefit of predator management on chick survival. Close

  Citation × Citation Citation Abstract Copy Title: The Effects of Frequency of Social Interaction, Social Cohesion, Age, and the Built Environment on Walking Author: Luhr, Gretchen Allison Year: 2016 The purpose of this dissertation was to explore, through a social ecological framework, the multifaceted effects of the neighborhood environment by investigating how dimensions of both the built environment and the neighborhood social context may interact to influence walking. Aesthetics, land use mix, crime, and pedestrian infrastructure were considered with respect to built environment walkability, and the neighborhood social context was conceptualized using measures of both social cohesion and social interaction with neighbors. This research used data from an Environmental Protection Agency (EPA)-funded study of 748 adults (18 years of age and older) residing in the Lents neighborhood in Portland, Oregon. Through a series of both multiple linear and logistic regression models, the analyses examined the specific pathways by which social interaction with neighbors, social cohesion, and age influenced the relationship between the built environment and walking behavior. Results suggest that both social interaction and social cohesion but not age moderate the effects of the built environment on walking. There was evidence of mediation, as well, for both social interaction and social cohesion. The implications of these findings for future research and policy are discussed.

  Citation × Citation Citation Abstract Copy Title: Migrant Remittances, Population Ageing and Intergenerational Family Obligations in Sri Lanka Author: Gamburd, Michele Ruth Year: 2015 As Sri Lanka’s population ages, its migrant women face a difficult choice: should they work abroad to remit money to provision their families, or should they stay at home to look after elderly kin? Although numerous studies have explored migration’s effects on children, fewer works focus on issues of elder care. This essay presents contextualizing information on transnational migration from Sri Lanka and the rapid ageing that is transforming the country’s population structure from a pyramid with many youth and few elders into a column. Using qualitative ethnographic data gathered from a labour-sending village in southern Sri Lanka, this anthropological essay considers social priorities around remittances and intergenerational family obligations for care work. Villagers make decisions about allocating able-bodied family members’ labour based on key concepts of filial duty, combined with an analysis of a family’s financial and social resources and the vulnerabilities of its members based on their gender and age. Critiquing assumptions about elders’ lack of economic activity, the essay notes their key role in facilitating labour migration. The data reveal the importance of gender roles, educational achievements, and generational shifts in evaluating emerging practices. In the future, intergenerational family obligations to mutual care will persist despite population aging. But as extended families shrink and care work grows more demanding, choices between elder care and migrant remittances will become more challenging.

Two facilities were selected in each of the aforementioned counties and researchers from our team surveyed the pedestrian environmental features of the surrounding area within a quarter-mile radius of the each facility. The survey data from each site was then distributed among two groups for qualitative and quantitative analysis. Quantitative analysis consisted of a compiling process that took the measures of quantifiable features (e.g. number of sidewalk breaks, abandoned lots, etc.) gathered in the field and standardized them in a single database, allowing an objective, cross-county comparison of the frequency of pedestrian environmental qualities identified as being indicative of age-friendliness. Qualitative analysis involved the distillation of recurring themes and observations reported by surveyors as they gave their impressions of the areas they visited, which were then used to interpret and appraise the accuracy of marketing materials issued by the target facilities. Both investigations were then contextualized by a separate group tasked with reviewing existing scholarship and impressions of academics working in geriatrics and other pertinent fields. Ultimately this examination also sought to identify the exact dimensions and characteristics of an age- friendly community, as well. Taken together, the research done in this project has lead us conclude that each county will have unique obstacles to overcome in pursuit of greater age friendliness yet they will need to act cohesively and cooperatively in order to do so. This will involve paying closer attention to how integrated the senior population is in the wider social sphere of their communities as well as working to ensure that crucial resources remain accessible to them wherever they may live.

  Citation × Citation Citation Abstract Copy Title: Studies on the distribution and habitat of Demodex folliculorum Author: Gimbol, Michael James Year: 1970 The present study was undertaken to determine the incidence of infestation with Demodex folliculorum, a skin mite parasitizing man, and to investigate those factors which influence its occurrence. These factors were the personal hygiene, sex, age and skin condition of the human host. A detailed view of the habitat of this parasite is also included so that the controversy surrounding its role as a possible pathogen or vector of disease could be explored in light of the current knowledge. A number of sites of infestation were sampled by a number of different techniques. The primary sample site was the nasal area of the face which was examined by slit lamp magnification after chemical application to partially expose the mites. A secondary site involved the eyelash follicles from which the lashes were epilated and examined for mites under the microscope. The 441 subjects examined in the nasal area were tabulated by age, sex and skin condition and the incidence of infestation was computed for each of five age groups. There was a definite increase in incidence of Demodex with the advancing age of the host and the normal and oily skin conditions appeared to be much more involved than the dry skin condition. A similar increase in incidence with advancing age was apparent in the 143 subjects whose eyelashes were examined. The results from both areas exhibited a statistical correlation between the age and skin condition of the human host and the presence of the mites. The explanation of the increase in incidence with the advancing age of the human host is based on the development and secretory rate of the sebaceous glands of the human host. Past studies have shown that Demodex lives in and around the sebaceous glands of the skin and feeds on sebaceous material and cellular debris. The face appears to be the habitat of optimum occurrence which corresponds to the distribution of sebaceous follicles and glands whose size and rate of secretion are greater that those over most of the body. The role of Demodex in the formation of ingrown hairs on the neck is discussed as a possible, new clinical entity. The influence of the host’s personal hygienic habits on demodectic infestation remains rather obscure. Although the accumulation of sebaceous material would tend to favor the maintenance of mites, the reservoirs of the sebaceous follicles of the face in which the mites are found are not affected by normal soap and water cleansing. Inhabitation of the eyelash follicles may be enhanced by ineffective cleansing, but more study is needed to determine the validity of this contention. The finding of selective sites of infestation on the human host led to speculation on the possibility of physiological races of Demodex. Although it is difficult to determine the validity of reports by earlier workers, there appears to be a decreasing trend in the incidence of Demodex folliculorum since its discovery over a century ago.

The sample was selected by a two- stage cluster sampling taken from the Southeast catchment area of metropolitan Portland, Oregon. From this sample of 787individuals, the survey was conducted by trained interviewers, using a questionnaire and personal interview. The data used in this research project were then extracted from the larger survey, and computed to determine the relationship of age, income and education to willingness to care for foster children. The data were extracted on the basis of the chosen variables of income, age and education and five questions relating specifically to willingness to care for foster children. As had been anticipated, the findings showed that the general population is not willing to care for foster children. However, certain significant findings were related to willingness to care for foster children. A significant relationship was found between income and willingness to care for foster children in that those respondents with incomes between $4,000-$20,000 expressed the most willingness to care for foster children while there was significant underrepresentation in both the highest and lowest income groupings to express a willingness to care for foster children with an almost lineal relationship of decreasing age with increasing willingness to care for foster children. There is no significant relationship, it was found, between education of the respondent and willingness to care for foster children. There is a lineal relationship of increasing willingness to care for foster children with increasing age of the foster child. Of those individuals expressing a willingness to care for foster children, there is no significant decrease in willingness because of physical disability, minor emotional problems or mental retardation. The results of this study have certain implication for recruitment and selection of foster parents. The findings indicate the need for further research to explore why more individuals in the population do not express a willingness to care for foster children, how such an interest can be encouraged and what criteria can be used in recruitment and selection.

Year: 2014 Although scale-up of antiretroviral therapy (ART) since 2005 has contributed to a decline of about 30% in the global annual number of human immunodeficiency (HIV)–related deaths and declines in global HIV incidence, estimated annual HIV-related deaths among adolescents have increased by about 50%, and estimated adolescent HIV incidence has been relatively stable. In 2012, an estimated 2,500 (40%) of all 6,300 daily new HIV infections occurred among persons aged 15–24 years. Difficulty enrolling adolescents and young adults in ART and high rates of loss to follow-up (LTFU) after ART initiation might be contributing to mortality and HIV incidence in this age group, but data are limited. Age-related differences in enrollment characteristics and outcomes were analyzed among 16,421 patients aged ≥15 years starting ART in seven African countries (Côte d’Ivoire, Nigeria, Swaziland, Mozambique, Zambia, Uganda, and Tanzania) during 2004–2012. Patient characteristics and outcomes were compared across three age groups: adolescents and young adults (15–24 years), middle-aged adults (25–49 years), and older adults (≥50 years). Compared with older adults, adolescents and young adults had higher LTFU rates in all seven countries, reaching statistical significance in three countries (Côte d’Ivoire, Mozambique, and Tanzania) in both crude and multivariable analyses. The higher risk for LTFU among adolescent and young adult ART enrollees, compared with older adults, increases their risk for death and increases the risk they will transmit HIV to seronegative sex partners. Effective interventions to reduce LTFU for adolescent and young adult ART enrollees could help reduce mortality and lower HIV incidence in this age group.

Although careful evaluations might be expected from conscientious raters, little is known about whether they might show more or less bias towards certain age groups. Therefore, in our study using a time-lagged design, we investigated the effects of rater conscientiousness on the performance evaluations of younger and older actual co-worker (N = 242). We found that raters who were more conscientious provided higher ratings for older workers than for younger workers on task performance and organizational citizenship behaviours. Specifically, we tested the model of mediated moderation, in which the relation between rater conscientiousness and ratee age predicts ratee-perceived conscientiousness, which in turn predicts performance ratings. The model was significant for older ratees, but not for younger ratees. We discuss our results in terms of the “similar to me” effects and implications for organizational practices.

  Citation × Citation Citation Abstract Copy Title: Relating Age, Decision Authority, Job Satisfaction, and Mental Health: A Study of Construction Workers Author: Zaniboni, Sara, Truxillo, Donald M., Rineer, Jennifer R., Bodner, Todd E. Year: 2016 Job autonomy is a critical job characteristic in the construction industry, with lower levels of autonomy compared to the general working population. Moreover, there is a paucity of work on individual difference moderators, such as age, considering the effect of job autonomy in important outcomes, such as job satisfaction and mental health. The purpose of the present study was to test a model of moderated-mediation, in which the interaction between decision authority (i.e., a type of autonomy) and age affects job satisfaction, which in turn affects mental health. The model tested is significant, and as expected, decision authority increased the satisfaction of older construction workers more than their younger colleagues, which in turn increased their mental health. We discuss our results in terms of selective optimization and compensation theory and implications for organizational practices.

  Citation × Citation Citation Abstract Copy Title: The biogeography of Oregon white oak (Quercus garryana) in central Oregon Author: Voeks, Robert Allen Year: 1981 The study proceeded as follows: The distribution of Q. garryana was mapped through field reconnaissance. Annual rings from fifteen trees were counted in order to establish age versus trunk diameter ratios. This greatly simplified the dating of trees. Transects were then run through individual groves to determine population age structures. These age structures, along with Q. garryana's distribution patterns, were graphically compared with historic temperature, precipitation, and growing season data. The effect of livestock grazing on oak reproduction was examined. Potential vagility of the species was evaluated by estimating the potential for acorn dispersion by airfall, streams, vertebrates, and the human (aboriginal) population. Finally, pollen evidence was scrutinized in conjunction with acorn dispersal rates in order to determine the longer term history of Q. garryana in this portion cf its range.

  Citation × Citation Citation Abstract Copy Title: Addressing the Needs of Nicaraguan Older Adults Living on the Edge: A University-community Partnership in International Service-learning Author: Neal, Margaret, Cannon, Melissa, DeLaTorre, Alan, Bolkan, Cory R., Wernher, Iris, Nolan, Elisabeth, Lopez Norori, Milton, Largaespada-Fredersdorff, Carmen, Brown Wilson, Keren Year: 2016 Nicaragua is a very low-income country entering a period of rapid aging with limited geriatric training for health care professionals. To help build capacity and to enhance student learning, a short-term international service-learning program was implemented in 2004 in partnership with the Jessie F. Richardson Foundation and Nicaraguan community stakeholders. Graduate and undergraduate students at Portland State University complete coursework for one term in the United States then travel to Nicaragua for about two weeks to participate in educational, research, and service activities, primarily in group homes for older Nicaraguans. Students learn about global aging, gerontology, community development, service learning, and Nicaraguan history and culture, then apply their gerontology-related knowledge by training direct care staff, older adults and their family members, and students. The authors describe the impetus for and evolution of the program, students’ evaluation of the program, faculty observations on program benefits and challenges, lessons learned, and future plans.
