About Paternal Voices In Adoption Narratives, Fu-Jen Chen

CLCWeb: Comparative Literature and Culture

In his article "About Paternal Voices in Adoption Narratives" Fu-jen Chen examines the emerging voices of fathers in adoption discourse. Breaking the reticence and challenging the stereotypical profile of birth fathers and the father overall, birth fathers in narratives resort to essentialism or victimhood, a cultural imagination in adoption discourse. Further, Chen examines adoption narratives by adoptive fathers arguing that their reluctance to call for a father-to-father relationship — either rivalry or alliance — indicates a sign of disavowal of both subjective splitness and the structural deadlock. Chen argues that in paternal adoption narratives writing does not emerge as a …

Conservative Evolution, Sustainability, And Culture, Gábor Náray-Szabó

CLCWeb: Comparative Literature and Culture

In his article "Conservative Evolution, Sustainability, and Culture" Gábor Náray-Szabó argues that evolution is conservative in the sense that throughout the history of the universe old constructs like elementary particles, amino acids, and living cells remained conserved while the world evolved/evolves in complexity. A similar process can be observed in cultural evolution as components of society and culture continue to evolve. Considering the increasing pressure on natural resources by material consumption, a close alliance between past, present, and future generations is unavoidable and thus Náray-Szabó posits that concepts of conservative evolution and sustainability are related. However, in order to avoid …

GEOTRACES is an international study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs), designed by marine geochemists to accelerate TEI research under a global program. Combining ocean sections, process studies, data synthesis, and modeling, GEOTRACES will identify and quantify the processes that supply TEIs at ocean boundaries as well as the physical and biological processes that redistribute TEIs within and between ocean basins. Constraining processes that remove TEIs from the ocean will enable complete mass budgets to be generated. Anticipated beneficiaries of GEOTRACES products include scientists studying the sustained health of marine ecosystems and their sensitivity …

Recombinant Human Follicle Stimulating Hormone And Growth Factors Improve The Meiotic And Developmental Competence Of Cat Oocytes, Theerawat Tharasanit, Chommanart Thongkittidilok, Thanida Sananmuang, Mongkol Techakumphu

The Thai Journal of Veterinary Medicine

In vitro embryo production has proven as potential tool for understanding factors involving developmental biology of embryos. This study aimed at examining the effects of recombinant human follicle stimulating hormone (rhFSH) on meiotic resumption and also on developmental competence of cat oocytes. Experiment 1 studied mRNA expression of luteinizing hormone (LH), follicle stimulating hormone (FSH), epidermal growth factor (EGF) and insulin like growth factor-1 (IGF-1) receptors (R) in cumulus cells. mRNA expression of LH receptor in cumulus cells after oocyte maturation was additionally examined. Experiment 2 examined the effect of different rhFSH concentrations (0.01, 0.05, 0.1 and 1 IU/ml) on …

Muscle Tension Induced After Learning Enhances Long-Term Narrative And Visual Memory In Healthy Older Adults, Kristy A. Nielson, Laura L. Wulff, Timothy J. Arentsen

Psychology Faculty Research and Publications

Arousing events are better remembered than mundane events. Indeed, manipulation of arousal, such as by muscle tension, can influence memory even when it occurs shortly after learning. Indeed, our founding study showed this approach can raise delayed memory performance in older adults to a level comparable to that of unaided young adults. Yet, systematic studies, especially those investigating different modalities or types of memory, have not been done. This study investigated the effects of a brief bout of isometric exercise via handgrip on narrative and visuospatial episodic memory in healthy elders. Forty-seven participants completed the Logical Memory subtest of the …

Applicability Of Latent Dirichlet Allocation To Multi-Disk Search, George E. Noel, Gilbert L. Peterson

Faculty Publications

Digital forensics practitioners face a continual increase in the volume of data they must analyze, which exacerbates the problem of finding relevant information in a noisy domain. Current technologies make use of keyword based search to isolate relevant documents and minimize false positives with respect to investigative goals. Unfortunately, selecting appropriate keywords is a complex and challenging task. Latent Dirichlet Allocation (LDA) offers a possible way to relax keyword selection by returning topically similar documents. This research compares regular expression search techniques and LDA using the Real Data Corpus (RDC). The RDC, a set of over 2400 disks from real …

A Course-Based Research Experience: How Benefits Change With Increased Investment In Instructional Time, Aparna Sreenivasan

Biology, Agriculture and Chemistry Faculty Publications and Presentations

There is widespread agreement that science, technology, engineering, and mathematics programs should provide undergraduates with research experience. Practical issues and limited resources, however, make this a challenge. We have developed a bioinformatics project that provides a course-based research experience for students at a diverse group of schools and offers the opportunity to tailor this experience to local curriculum and institution-specific student needs. We assessed both attitude and knowledge gains, looking for insights into how students respond given this wide range of curricular and institutional variables. While different approaches all appear to result in learning gains, we find that a significant …

The Genetic Drift Inventory: A Tool For Measuring What Advanced Undergraduates Have Mastered About Genetic Drift, Rebecca M. Price, Tessa C. Andrews, Teresa L. Mcelhinny, Louise S. Mead, Joel K. Abraham, Anna Thanukos, Kathryn E. Perez

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures upper-division students’ understanding of this concept. We used an iterative approach that included extensive interviews and field tests involving 1723 students across five different undergraduate campuses. The GeDI consists of 22 agree–disagree statements that assess four key concepts and six misconceptions. Student scores ranged from 4/22 to 22/22. Statements …

Environmental Correlates Of Assemblages Of Fishes In The Tilostoc River Of Central Mexico, Juan Manuel Rivas-González, Felipe De Jesús Rodríguez-Romero, María De Lourdes Ruiz-Gómez, Diego Alfonso Viveros-Guardado, Christopher M. Taylor

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Ordination, correlation, and regression analyses were used to identify trophic and taxonomic distributional patterns of fishes in the Tilostoc River (located west of Valle de Bravo Lake in the Middle Balsas Basin, central Mexico) and associations of these patterns with environmental variables. Nonmetric multidimensional scaling analysis indicated that trophic and taxonomic assemblages corresponded similarly to measured environmental gradients, especially elevation and velocity of currents. We also compared the trophic structure of assemblages of fishes of the Tilostoc River to that of Terreros Creek, a temperate system of similar size and species richness but with a taxonomically different group of species. …

Classifying Lower Extremity Muscle Fatigue During Walking Using Machine Learning And Inertial Sensors, Jian Zhang, Thurmon Lockhart, Rahul Soangra

Physical Therapy Faculty Articles and Research

Fatigue in lower extremity musculature is associated with decline in postural stability, motor performance and alters normal walking patterns in human subjects. Automated recognition of lower extremity muscle fatigue condition may be advantageous in early detection of fall and injury risks. Supervised machine learning methods such as Support Vector Machines (SVM) have been previously used for classifying healthy and pathological gait patterns and also for separating old and young gait patterns. In this study we explore the classification potential of SVM in recognition of gait patterns utilizing an inertial measurement unit associated with lower extremity muscular fatigue. Both kinematic and …

From The Inside Out, And Through., Dominique Ovalle

The Transdisciplinary STEAM+ Journal

These photographs describe “Science” born of consumerism, hijacked by me, economically disenfranchised, or rather—temporarily embarrassed, artist. I was putzing around Malibu—my old college stomping ground, looking for free food; maybe a sample of some gourmet $5 chocolate, and all I got were these photographs.

My artwork is a result of the exploration of materials through process. The sculptures I make are the solutions to problems of how to combine materials, and create structure and form that I am able to build and transport on my own.

The Quantified Self, Behind The Cover Art, Leslie Love Stone

The Transdisciplinary STEAM+ Journal

We lead quantified lives. The information we send and receive through our computers, CD players, and smart phones is coded in ones and zeroes. We exist as numerical accounts, license numbers, and login IDs. Anyone who has ever waited on hold for a live customer service representative understands the desire to be treated like a person, not a number. We each want acceptance for our inherent peculiarities and consideration for our circumstance—conditions we believe extrinsic to numbers.

Preserving The Historic Garden Suburb: Case Studies From London And New York, Jeffrey A. Kroessler

Suburban Sustainability

The garden city or garden suburb was a response to the social and environmental ills of cities at the turn of the twentieth century. Letchworth Garden City, Hampstead Garden Suburb, and Welwyn Garden City were built outside London in the early 1900s, and each remains a highly desirable place of residence today. From the start, each was tightly regulated, and remains so a century later. By protecting the appearance and enhancing property values, the strict application of historic preservation principles contribute to the long-term sustainability of each place. Similar garden suburbs were built in the borough of Queens in New …

The Medical Sociologists' Contribution To The Interdisciplinary Geriatric Assessment Unit: A Sociology "With" Medicine, Jeffrey Michael Clair

Sociological Practice

Observations are drawn from field experience to explicate the role of the medical sociologist within geriatric clinical practice—a case presentation of a sociology "with" medicine. A sociology "with" medicine is presented as promoting the institutionalization of medical sociology as a special field within, yet independent of, medicine. The aim is to promote initiatives which generate and lest social theory while expanding collaboration with medical clinicians, researchers, and educators to maximize the application of social scientific data to patient care. The goals of specialized geriatric practice are then described. Next, the substantive functions and activities of the medical sociologist in a …

Everyday Lives Of The Elderly: A Dimensional Analysis, David Kowalewski, Steven Peterson

Sociological Practice

Considerable dissension surrounds the number and composition of the domains comprising the daily lives of the elderly. The present study employs an array of biological, economic, political, social, and psychological data obtained from a house-to-house survey of elderly citizens to derive a mapping of dimensionality. Factor analysis of the data isolated eight domains: Poor Health, Disengagement, Self-Sufficiency, Female Aging, Meaningful Employment, Political Faith, Self-Starting, and Stoicism. External validation supported the factor solution and highlighted the impact of dietary and economic deficits on the problems of the aged.
