  Citation × Citation Citation Abstract Copy Title: Dismantling the Gate, Crossing the Threshold: The Promise of Producerly Paratexts in Building an Innovative, Responsive, and Representative Book Industry Author: Athey, Dory Year: 2016 Aisha Saeed was the first to use the hashtag that would fuel what was (and continues to be) arguably the first digital campaign to speak loudly and directly to publishers and booksellers about the mis-and underrepresentation of nonwhite, differently abled, and queer populations in young adult and children’s literature. Though Saeed’s original tweet received only eleven retweets and seven likes, two years later, the #WeNeedDiverseBooks hashtag is now just a piece of the larger organization that generated more than 333,000 dollars in 2014 (its first year as an organization) and continues to promote large-scale programming in schools, organize festivals, award grants, and develop partnerships with organizations and companies from all sides of the YA and children’s book industry––from publishers to librarians to booksellers. Today, the organization functions as a persistent knock on the gatekeepers’ door, demanding entry through the gate and responsiveness from the keepers. The reach of We Need Diverse Books is huge, its message loud, and it’s difficult to know where and how to categorize this new type of influence on writing and publishing. How do digital communities and conversations -- organized by hashtags and hosted on social networking and micro-blogging sites -- shape and inform how and what we read and publish? Still dominated by white, able bodied, and cisgender faces, brains, and experiences (see Lee & Low Books recently released results of the Diversity Baseline Survey), the publishing industry today is challenged to the next steps. What are they? How can publishers leverage a new and rapidly evolving media environment to stay accountable to readers and audiences? The following examination posits that these emergent, participatory digital environs might be productively considered paratexts, that is, the pieces of a book that surround and extend it, that “present…and make it present…to assure its presence in the world.”5 Taking literary critic Gérard Genette’s original concept of paratext and introducing it to media theorist John Fiske's concept of "the producerly text," we arrive at what I call the "producerly paratext," which not only presents and makes present the book, but also invites outside parties to participate in that presentation. Forging spaces for that participation is the way forward for the book industry and its inhabitants who are striving, and often stumbling, to keep up with ever more rapid technological change, meet a more and more elusive bottom line, and build a more responsive and representative industry. This exploration will take three turns. The first is a twofold examination that defines the theoretical framework of the producerly paratext and then brings it into conversation with book history, keeping a keen eye toward the capacity of emerging technology to enable paratexts that are sites of resistance and reformulation. The second is a compendium of examples of paratexts that bring that examination to bear in the present moment of media and the book industry. Bringing the We Need Diverse Books campaign’s use of networked, digital tools into conversation with contemporary conceptualizations of paratext yields a dynamic vision of a publishing industry poised to actively become more innovative, responsive, and representative. The third is a blueprint for producerly paratext production: a consideration how the publishing industry might move forward on this particular track, work with audiences to understand paratexts, and build new producerly ones that both hold publishers accountable and function as spaces of resistance and reformulation––paratexts that continue to dismantle the gate and let readers cross the threshold.

  Citation × Citation Citation Abstract Copy Title: Morphological and cytological studies on Arceuthobium (Viscaceae) in relationship to host phloem with studies on the healthy phloem in Pinus sabiniana (Pinaceae) Author: Alosi, Margaret Carol Year: 1980 Anatomical and developmental tissue relationships between Arceuthobium spp. endophytic tissues and host vascular tissues were examined by light and transmission electron microscopes. The host-parasite pairs studied were Psudotsuga menziesii/A. douglasii, Tsuga heterophylla/A. tsugense, Pinus sabiniana/A. occidentale, and P. lambertiana/A. californicum. The morphological form and growth characteristics of A. douglasii in different aged host tissues was found to be coordinated with growth and maturation of the host. It is proposed that morphological forms of Arceuthobium endophytic tissue be categorized as (1) primary, (2) diffuse-secondary, or (3) localized-secondary in order to semantically clarify the relationship of endophytic morphology with primary or secondary growth stages of host tissue. In localized-secondary endophytic forms, the parasite integrates with host rays to form multiseriate infected rays. At both the light and electron microscope level, parasite cells can usually be identified by their distinctive chromocentric nuclei and abundant lipid bodies or lipid ghosts. Sinker cells of Arceuthobium have unusual plastids which resemble etioplasts and which do not store starch. Sinker cells have distinctive mitochondria with unusually large nucleoid areas. They have abundant endoplasmic reticulum. Wall/plasmalemma specializations increase the membrane surface area in relation to cell volume in sinker cells. The walls of host and parasite are fused at the middle lamella common to both organisms and the organisms share a common apoplast. Pit-like regions in the fused walls of the host/parasite interface were commonly seen in light microscope studies, although such interspecific pitting is seen less than intraspecific pitting. It was determined that, whereas intraspecific pits are traversed by complete plasmodesmata, interspecific pits had no plasmatic channels, or, only half plasmodesmata on the host side of the pit. In one case a half plasmodesmata was seen on the Arceuthobium side of the host/parasite interface. On the basis of the electron microscope studies of the host/parasite interface it appears that plasmatic connections between host and parasite do not normally occur. Because of this plasmatic isolation it can be concluded that nutrient acquisition does not involve direct flow of nutrients via interspecific symplastic bridges. Therefore, photosynthate, normally housed within phloem cells, must be leaked into the common apoplast of both host and parasite before becoming available for absorption into the parasite symplast. Since host and parasite lack symplastic continuity but share a common apoplast, apoplastically-mobile herbicides should be tested for their ability to accumulate in parasite tissues. Cytopathological effects on the host cells were relatively mild although a significant increase in the ratio of radial to axillary vasculature was noted in infected tissue. Other modifications included a tendency for increased numbers of specialized phloem parenchyma (Strasburger cells) in infected rays. No apparent anomalies were observed in conjunction with host sieve cell structure and development. The structure and ontogeny of healthy P. sabiniana phloem was also studied. It was found that the sieve element reticulum (SER) of mature sieve cells is derived from plastids during the maturation of the sieve cell. After maturation some of the SER membranes seem to disassociate into individual 60 (ANGSTROM) fibrils. These fibrils then reassociate and appear to be condensed into paracrystalline bodies which, in turn, participate in the generation of new membranes in the mature sieve cell. Because of their plastid origin, the SER membranes may have energy transducing and ionic pump capabilities that commonly are associated with plastid membranes. Such specialized functions of SER may contribute to the translocating capacities of sieve cells.

  Citation × Citation Citation Abstract Copy Title: A Study of Oxygen Precipitation in Heavily Doped Silicon Author: Graupner, Robert Kurt Year: 1989 Gettering of impurities with oxygen precipitates is widely used during the fabrication of semiconductors to improve the performance and yield of the devices. Since the effectiveness of the gettering process is largely dependent on the initial interstitial oxygen concentration, accurate measurements of this parameter are of considerable importance. Measurements of interstitial oxygen following thermal cycles are required for development of semiconductor fabrication processes and for research into the mechanisms of oxygen precipitate nucleation and growth. Efforts by industrial associations have led to the development of standard procedures for the measurement of interstitial oxygen in wafers. However practical oxygen measurements often do not satisfy the requirements of such standard procedures. An additional difficulty arises when the silicon wafer has a low resitivity (high dopant concentration). In such cases the infrared light used for the measurement is severely attenuated by the electrons of holes introduced by the dopant. Since such wafers are the substrates used for the production of widely used epitaxial wafers, this measurement problem is economically important. Alternative methods such as Secondary Ion Mass Spectroscopy or Gas Fusion Analysis have been developed to measure oxygen in these cases. However, neither of these methods is capable of distinguishing interstitial oxygen from precipitated oxygen as required for precipitation studies. In addition to the commercial interest in heavily doped silicon substrates, they are also of interest for research into the role of point defects in nucleation and precipitation processes. Despite considerable research effort, there is still disagreement concerning the type of point defect and its role in semiconductor processes. Studies of changes in the interstitial oxygen concentration of heavily doped and lightly doped silicon wafers could help clarify the role of point defects in oxygen nucleation and precipitation processes. This could lead to more effective control and use of oxygen precipitation for gettering. One of the principal purposes of this thesis is the extension of the infrared interstitial oxygen measurement technique to situations outside the measurement capacities of the standard technique. These situations include silicon slices exhibiting interfering precipitate absorption bands and heavily doped n-type silicon wafers. A new method is presented for correcting for the effect of multiple reflections in silicon wafers with optically rough surfaces. The technique for the measurement of interstitial oxygen in heavily doped n-type wafers is then used to perform a comparative study of oxygen precipitation in heavily antimony doped (.035 ohm-cm) silicon and lightly doped p-type silicon. A model is presented to quantitatively explain the observed suppression of defect formation in heavily doped n-type wafers.

  Citation × Citation Citation Abstract Copy Title: Primary Care and Mental Health Integration in Coordinated Care Organizations Author: Baker, Robin Lynn Year: 2017 The prevalence of untreated and undertreated mental health concerns and the comorbidity of chronic conditions and mental illness has led to greater calls for the integration of primary care and mental health. In 2012, the Oregon Health Authority authorized 16 Coordinated Care Organizations (CCO) to partner with their local communities to better coordinate physical, behavioral, and dental health care for Medicaid recipients. One part of this larger effort to increase coordination is the integration of primary care and mental health services in both primary care and community mental health settings. The underlying assumption of CCOs is that organizations have the capacity to fundamentally change how health care is organized, delivered, and financed in ways that lead to improved access, quality of care, and health outcomes. Using the Rainbow Model of Integrated Care (RMIC), this study examined the factors that impact organizational efforts to facilitate the integration of primary care and mental health through interviews with executive and senior staff from three CCOs. The RMIC focuses attention on the different levels at which integration processes may occur as well as acknowledges the role that both functional and normative enablers of integration can play in facilitating integration processes within as well as across levels. The following research question was explored: What key factors in Oregon's health care system impede or facilitate the ability of Coordinated Care Organizations to encourage the integration of primary care and mental health? Using a case study approach, this study drew upon qualitative methods to examine and identify the factors throughout the system, organizational, professional, and clinic levels that support CCO efforts to facilitate the integration of primary care and mental health. Fourteen primary interviews were conducted with executive and senior staff. In addition, eleven secondary interviews from a NIDA funded project as well as twenty-four key CCO documents from three CCOs were also included in this study. The RMIC was successful in differentiating extent of CCO integration of primary care and mental health. Findings demonstrate that normative and functional enablers of integration were most prevalent at the system and organization level for integrating mental health into primary care for these three CCOs. However, there was variation in CCO involvement in the development of functional and normative enablers of integration at the professional and clinic levels. Normative and functional enablers of integration were limited at all of the RMIC levels for integrating primary care into community mental health settings across all three CCOs. The Patient-Centered Primary Care Home model provided CCOs with an opportunity to develop functional and normative enablers of integration for integrating mental health in primary care settings. The lack of a fully developed model for integrating primary care services in community mental health settings serves as a barrier for reverse integration. An additional barrier is the instability of community mental health as compared to primary care; contributing factors include historically low wages and increased administrative burden. System wide conversations about where people are best served (i.e., primary care or community mental health) has yet to occur; yet these conversations may be critical for facilitating cross-collaboration and referral processes. Finally, work is needed to create and validate measures of integration for both primary care and community mental health settings. Overall findings confirm that integrating primary care and mental health is complex but that organizations can play an important role by ensuring the development of normative and functional enablers of integration at all levels of the system.

  Citation × Citation Citation Abstract Copy Title: Decision Model for Selection of Technologies to Reduce IT Operations Energy Cost in a Mid Size Firm Author: DeLay, Robert, Honnappa, Lokesh, Chiamsiri, Vorakarn, Soysa, Dinesh, Cho, Yonghee Year: 2010 Most businesses today rely on IT systems in order to not only enhance their productivity of business processes but also increase their successes relative to the company strategies. Due to decreasing costs of hardware and software, companies are increasingly implementing new systems to solve business problems in a cost effective fashion. This has led to the proliferation of hardware systems within many companies. Perhaps those most affected are the mid-range companies, like the one in this study, that require sophisticated systems but oftentimes lack sufficient IT staff and budget to meet the strategic ambitions of the company. In this context, power consumption has become a consideration that must be included in IT decisions. For example, IEEE Spectrum projects that within five years (i.e., by 2015), the cost of power for data centers will surpass the cost of the equipment [1]. This study focuses on the technology purchasing decisions of a mid-sized firm (500 employees) that increase the energy efficiency of its computing systems while meeting its business objectives. For example, if company growth requires implementation of a more robust and up-to-date customer tracking system and includes hiring ten new employees, what course should be followed to ensure a reduction in energy consumption as well as the achievement of company business goals? Should the company purchase a couple of additional servers with limited capacity for growth or should the company replace 20 aging rack servers with six state-of-the-art servers for consolidation and the hosting of virtual machines? And should the company supply the new employees with new CRT monitors or recycle some that have been in storage? There are several alternatives that the firm can use to achieve its goals. This paper evaluates four technologies for their impact on the reduction of energy consumption by company’s computing systems: server virtualization, desktop virtualization, replacement of existing CRT monitors and PC power management. Based on the four technologies, we have developed a decision model for identifying the alternative the firm should invest in for improving the energy efficiency of their IT systems. The decision model is based on experts’ opinions by assessing several factors of each technology. The next section addresses how we developed this decision model using decision theory and experts’ judgments.

In 2009, Oregonians spent more than $14 billion on energy consumption. Oregon has been a leader in conservation energy, in the development of renewable energy and in growth of green jobs. Promoting a diversity of renewable energy generating resources in Oregon is good energy policy for a state that has an electricity system heavily dependent on hydropower and increasingly dependent on fossil fuels. Oregon is already making use of renewable technologies including hydro, wind, direct use of geothermal, biomass, and solar. By building on these achievements, Oregon thrives to continue to be a leader on renewable energy policy and aims to meet a large fraction of its energy needs with new renewables by the year 2025. Governor Kulonguski says “We can make Oregon the national leader in renewable energy and renewable product manufacturing. Development of renewable energy will lessen our reliance on fossil, protect Oregon’s clean air and create jobs.”[2] Some of the benefits of renewable energy include risk mitigation of the fluctuations in prices and availability of fossil fuels towards a more sustainable source. Economic development and job creation though locally established power plants. Environmental benefits from using abundantly available natural sources that causes far lesser impact on the environment. Objective of this paper is to propose an economic portfolio model for sustainable energy generation in the State of Oregon by year 2020. We are considering Biomass, Hydroelectric, Solar, Wind and Geothermal energy sources. We also project Oregon’s future supply and generation requirements in terms of costs and plant capacity to fulfill their demand for energy though in-state renewable energy sources.

  Citation × Citation Citation Abstract Copy Title: An Evaluation of Moderating Influences of Employee Proactive Personality: Empowerment and Political Skill Author: Ford, Deborah Kaylee Year: 2011 An action-orientation within the workplace is often sought out by organizations as a source for competitive advantage. Organizational leaders are increasingly reliant on independently driven employees that will take action without being instructed to do so. Toward this effort, proactive personality has become increasingly popular within the literature as a personality trait associated with an employee's propensity to take charge of situations and demonstrate initiative to make a positive impact. In identifying potential variables that will moderate the effects of proactive personality, a highly relevant construct is empowerment. Proactive personality is thought of as a trait, whereas empowerment can be thought of as the contextual counterpart. In this study, I research both psychological empowerment as an employee interpretation of organizational conditions, such as feelings of self-efficacy, control, and flexibility for action (Arnold, Arad, Rhoades, & Drasgow, 2000) and structural empowerment as the influence of situational workplace context (Kanter, 1977). Despite the theoretical overlap between proactive personality and empowerment, very little has been done to integrate or investigate these variables together to evaluate their relative influences on important outcomes. Given that limited concentration has been focused on boundary conditions of proactive personality, employee political skill is hypothesized as a moderator that will encourage the attainment of important organizational outcomes (i.e., job task performance, job satisfaction) and minimize negative outcomes (i.e., occupational stress and strain) from proactive personality and empowerment. This study is a more complete investigation of proactive personality that not only provides a meaningful theoretical examination, but also informs applied practice. Despite a number of theoretical links between proactive personality and empowerment, the two constructs have been investigated in isolation from one another. Therefore, the relationship between empowerment and political skill is largely unknown. It is unclear whether empowerment and political skill are both necessary to realize optimal results or whether being high on both leads to exponentially better outcomes. This study included 252 nurses from union organizations in Oregon, Florida, and Missouri that registered and were invited to participate (53%). They were surveyed across two points in time, 176 participated at Time 1 and Time 2 and 76 participated in only Time 1. Results did not show support for my hypotheses that improvements would be observed for those high on any two research variables: proactive personality, empowerment, and political skill. However, results consistently support a compensatory model. In general, task performance, perceived effectiveness, and satisfaction with quality of care improved when nurses were high on either proactive personality or empowerment (either structural or psychological). Those high on either proactive personality or political skill had higher levels of task performance and satisfaction with quality of care. Similarly, those high on either structural empowerment or political skill had higher levels of task performance and satisfaction with quality of care. Only when a nurse was low on both variables in the model did they show reduced benefits. Several clear practical solutions are readily apparent based on study results. Given that empowerment can be manipulated within an organizational culture and proactive personality can be integrated with selection systems, the results are important for organizational leaders and organizational development consultants. Similarly, this research adds greatly to the literature on political skill, an area that is relatively new. By examining the moderating influence of political skill, this adds to the theoretical advancement of the three constructs while also informing practitioners regarding potential selection, training, and organizational design. Political skill has been seen as an attribute with the capacity to change over time with training, experience, and mentoring (Ferris, Perrewé, Anthony, & Gilmore, 2000). Therefore, the practical implications for organizations are clearly evident. Further, given that both proactive personality and empowerment have received limited evaluation into their boundary conditions, an evaluation of potential moderators helps advance into the understanding of the processes related to action within the workplace.

Viral metagenomics offers a potential means of establishing a more comprehensive view of virus diversity and evolution, as vast amounts of new sequence data becomes available for comparative analysis.Metagenomic DNA from virus-sized particles (smaller than 0.2 microns in diameter) was isolated from approximately 20 liters of sediment obtained from Boiling Springs Lake (BSL) and sequenced. BSL is a large, acidic hot-spring (with a pH of 2.2, and temperatures ranging from 50°C to 96°C) located in Lassen Volcanic National Park, USA. BSL supports a purely microbial ecosystem comprised largely of Archaea and Bacteria, however, the lower temperature regions permit the growth of acid- and thermo-tolerant Eukarya. This distinctive feature of the BSL microbial ecosystem ensures that virus types infecting all domains of life will be present. The metagenomic sequence data was used to characterize the types of viruses present within the microbial ecosystem, to ascertain the extent of genetic diversity and novelty comprising the BSL virus assemblage, and to explore the genomic and structural modalities of virus evolution.Metagenomic surveys of natural virus assemblages, including the survey of BSL, have revealed that the diversity within the virosphere far exceeds what has currently been determined through the detailed study of viruses that are relevant to human health and agriculture. The number of as-yet-uncharacterized virus protein families present in the BSL assemblage was estimated by clustering analysis. Genomic context analysis of the predicted viral protein sequences in the BSL dataset indicates that most of the putative uncharacterized proteins are endemic or unique to BSL, and are largely harbored by known virus types. A comparative metagenomic analysis approach identified a set of conserved, yet uncharacterized BSL protein sequences that are commonly found in other similar and dissimilar environments.New sequence data from metagenomic surveys of natural virus assemblages was also used to better characterize and define known virus protein families, as some of the viruses found in the BSL environment represent distant relatives of well-characterized isolates. By comparing viral genes and protein sequences from these highly divergent species, it is possible to better understand the dynamics of adaptation and evolution in the virosphere. Additionally, as structures of virus proteins continue to be experimentally determined by X-ray crystallography and cryo-electron microscopy, a merger of structural and metagenomic sequence data allows the opportunity to observe the structural dynamics underlying virus protein evolution.Capsid (structural) proteins from two distinct Microviridae strains; a globally ubiquitous and highly sequence-diverse virus family, were identified in, and isolated from the BSL metagenomic DNA sample. These BSL capsid protein sequences, along with several other homologous sequences derived from metagenomic surveys and laboratory isolates, were mapped to the solved structure of a closely related capsid protein from the Spiroplasma phage-4 microvirus. Patterns of amino acid sequence conservation, unveiled by structure-based homology modeling analysis, revealed that the protein sequences within this family exhibit a remarkable level of plasticity, while remaining structurally and functionally congruent.Lateral gene transfer is thought to have had a significant impact on the genomic evolution and adaptation of virus families. Genomic context analysis was also utilized to identify interviral gene transfer within the BSL virus assemblage. An ostensibly rare interviral gene transfer event, having transpired between single-stranded RNA and DNA virus types, was detected in the BSL metagenome. Similar genomes were subsequently detected in other ecosystems around the globe. The discovery of this new virus genome dramatically underscores the scope and importance of genetic mobility and genomic mosaicism as major forces driving the evolution of viruses.The analyses conducted herein demonstrate the many ways in which viral metagenomic sequence data may be utilized to not only evaluate the composition of a natural virus assemblage, but to discover new viral genes, and to better understand the dynamics of both genomic and structural evolution within the virosphere.

  Citation × Citation Citation Abstract Copy Title: The Effect of Temperature on Phenotypes of the Invasive European Green Crab: Physiologic Mechanisms that Facilitate Invasion Success Author: Kelley, Amanda Year: 2013 Invasion physiology is an emerging field that endeavors to understand the influence of physiological traits on the establishment of non-native species in novel environments. The invasive European green crab,Carcinus maenas, is one of the world's most successful aquatic invaders, and is currently distributed across temperate marine ecosystems globally. The work presented here explored the thermal physiology of this species, and has highlighted several physiological traits that have likely influenced establishment success. Intraspecific comparisons of crabs sampled from the northern and southern edges of their recipient, or invaded range on the west coast of North America have identified both organismal and cellular physiological difference with respect to upper and lower thermal tolerances. Crabs sampled from British Columbia, Canada (BC) had a significantly lower mean upper thermal tolerance threshold and heat shock protein synthesis, Hsp70, compared to their warm acclimated conspecifics sampled from California (CA). These differential physiologic responses may be rooted in the disparate natural thermal habitats that each population occupies within their respective environments. The ability of this species to extend its current range limits was also investigated. Range expansion to the south has been limited, and is likely restricted by this species lack of adaptation to warmer temperatures. Because range expansion has been chiefly northward, characterizing this species' response to cold stress can identify whether colder temperatures poleward may limit further range expansion. Cold tolerance capacity was determined in the laboratory, and crabs sampled from Vancouver Island, British Columbia were able to withstand the over-wintering thermal regime that occurs in Sitka, Alaska, a site that is currently beyond the range limits of this species. Furthermore, intraspecific assessments found that the cold acclimated BC population exposed to cold shock significantly down regulated protein levels of cyclin D1, cell cycle modulator. Distinct differences in carapace width (CW) were detected along the thermal gradient present in the green crabs' range. This variation in body size was utilized to the test the temperature size rule hypothesis for ectotherms. Simply stated, the temperature size rule is the tendency for ectotherms to develop slower but mature to a larger body sizes at cooler temperatures. The results supported this hypothesis as crabs sampled from the warm portion of the range were found to be smaller than crabs sampled from the colder portion of the range. This pattern was detected along the native range as well. Differences in body size have the potential to influence the scope of invasion; larger individuals are generally more fecund and longer lived, which can increase both the intensity and frequency of larval dispersal that could further propel range expansion. The physiologic properties that the green crab possesses which may influence invasion success were examined using peer-reviewed literature with the aim of determining if these physiological traits confer invasion success across taxa. This analysis tested four hypotheses: 1) Broad geographic temperature tolerances (thermal width) confer a higher upper thermal tolerance threshold when comparing invasive and native species. 2) The upper thermal extreme experienced in nature is correlated with upper thermal tolerance threshold. 3) Protein chaperone expression, a cellular mechanism underlying thermal tolerance threshold, is greater in invasive organisms than in native ones. 4) Acclimation to higher temperatures can promote a greater range of thermal tolerance for invasives compared to natives. These preliminary results generally support the four stated hypotheses, and provide a solid foundation for further studies to explore and identify physiologic traits that facilitate invasion success. Overall, these studies investigated the thermal physiology ofCarcinus maenasfrom an invasive metapopulation and have brought about significant advances in our understanding of what physiologic traits correlate to invasion success in this species. In addition, the data presented here can aid resource managers in identifying habitats, based on thermal tolerance measurements that fit the criteria for invasion. Understanding how invasive organisms vary with respect to thermal tolerance can aid our understanding the patterns and processes of species invasions.
