  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.

  Citation × Citation Citation Abstract Copy Title: Age Discrimination: Potential for Adverse Impact and Differential Prediction Related to Age Author: Fisher, Gwenith G., Truxillo, Donald M., Finkelstein, Lisa M., Wallace, Lauren E. Year: 2017 The proportion of workers in their 50s, 60s, and 70s is larger than ever before. Current workforce trends indicate global increases in retirement ages and that many individuals are working until later ages than in decades past, and older people are applying for jobs and at later ages. Research to date on age discrimination in selection has focused primarily on disparate treatment or intentional discrimination. However, based on accumulated knowledge about age-related changes in cognitive and physical abilities as well as changes in personality and work motivation across the life course, we suggest that more attention be paid to the possibility of age-based subgroup differences on selection procedures, manifested as adverse impact and differential prediction. We provide recommendations to guide future human resource management research and practice.

  Citation × Citation Citation Abstract Copy Title: Does temperature preference change in aging flies? Author: Giebultowicz, T., Chow, E., Chase, Teresa We set out to see if a biomarker of aging in could be found in temperance preference since it was found previously to be a predictable circadian rhythm in young flies. Since flies live 70 days it can be said that a day in the life of a fly is like a year in the life of a human. This is important because in our lab we use flies as a model organism for studying aging as to then apply to our understanding of human health and longevity. Currently most labs use over all lifespan as their biomarker of aging, but we need something that can be seen throughout the lifespan, not just at the end of it. We are always on the lookout for ways to see how aging effects the different conditions and genetic mutations we use. First we chose both wild types and genetic mutations to test for variation in results. We aged these flies at different intervals so as to have different ages to compare together. We further put these flies in alternating light-dark conditions to test together at different time points along the circadian 24 hour clock. The flies were tested in an apparatus that had a hot and cold side, with room temperature estimated in the middle along a temperature gradient that was established. There were 4 channels that separated the different groups of 50 individuals which labeled by their time of time, age, gender and genotype. After 30 minutes, a picture was taken to determine each of their temperature preference. No fly was retested and instead many bio repeats were used to establish a trend. Each fly was given a xy coordinate which a formula and computer program assigned a temperature to each. This data was averaged using statistical test and used to plot graphs of how the rhythm of temperature preference changed from young and old, and compared to the previously reported data.

Aquatic animals possess surprising similarities to humans in reproductive signaling that are simplified or elaborated for life underwater, making them useful for studying reproductive control. In this thesis, killifish and sea anemones are used as models for reproductive function and aging. The aging model Nothobranchius (killifish) was used to investigate circadian rhythms and clock gene expression in reproductive tissues, and effects of the anti-aging compound resveratrol (RSV) were examined to elucidate the role of clock genes in fertility. Weak connections were found between gonadal clock gene expression and age, and RSV altered expression over time and shifted rhythmic patterns in old fish, suggesting that it may modulate circadian rhythms with age. Additionally, to understand the physiological mechanisms behind coral spawning for conservation and elucidate hormonal evolution, functions of the cnidarian leucine-rich repeat-containing G protein-coupled receptor LGRA2 were investigated in the model sea anemone Aiptasia pallida. LGRA2 was expressed near gonadal regions of sexually developed sea anemones, activated by gonadotropins, and modulated by estrogen, indicating that it is involved in regulating reproduction similarly to its mammalian homologs luteinizing hormone receptor and follicle stimulating hormone receptor. These projects together provide a One Health view of reproductive signaling and aging.

  Citation × Citation Citation Abstract Copy Title: The effects of population age on trade Author: Peterson, Zack T. This paper empirically examines the effects of population aging on international trade using a cross-country panel data set for a select group of 22 OECD countries. Other recent studies have examined the effects of population age on other economic variables such as growth, savings, and investment but none till now have considered age related effects on international trade. I use a simple linear empirical model to capture any age related effects on trade along with two different model specifications in this paper; one is a simple OLS and the other is a fixed effects linear trend adjusted OLS specification. The estimated results are then adjusted for heteroskedasticity and autocorrelation via the use of the Newey-West HAC estimator to account for problems common to cross-county panel data sets. I conclude that there is indeed, a positive and statistically significant (though not very robust relationship) between a country's population age and its export to GDP ratio. There are no statistically significant effects on other total trade, trade balance or import variables. Title: The effects of population age on trade Author: Peterson, Zack T.

Strong self-regulation in early childhood is a key predictor of academic and social success from elementary school through college (McClelland et al., 2012). This study analyzed the influence of the age of the child’s parent on the child’s self-regulation as measured by the HTKS (Head-Toes-Knees-Shoulders) measure. Relations between children’s self-regulation scores and their parent’s age were initially examined and then were tested again after controlling for family income and child age. Higher child self-regulation was significantly related to having older parents. However, this correlation lost significance after family income (Head Start status) and child age were controlled. These results suggest that although parent age and child self-regulation are significantly related, family income and child age are stronger predictors of children’s self-regulation.
