Winter Feeding Strategies: Implications Of Corn Supplementation On Gestating Beef Cows, Amelia R. Tanner

Animal Sciences

Overwintered, gestating beef cows fed low-quality forage are at risk of nutrient restriction which can lead to compromised growth and poor carcass quality in their offspring. In many species, poor maternal nutrition also results in reduced uteroplacental hemodynamics and fetal growth. To better understand how different nutritional paradigms influence the beef cow, our lab has examined the impacts of nutrient restriction and diet composition on uterine hemodynamics. Previous research suggests that dietary intake or protein supplementation alone does not increase uterine blood flow. The current study examined the effects of dietary starch supplementation and our findings indicate that increasing starch …

Busy Intersections: A Framework For Revitalization, George Tucker Childs

Applied Linguistics Faculty Publications and Presentations

This paper reports on the applicability of a pedagogical model for use in West Africa drawn from adult literacy practices in the United States. It proposes bridging the gap between linguists, teachers, and community organizers, and building on the ethnographic skills of language documenters. One increasingly important goal of language documentation has been “creating and mobilizing documentation in support of pedagogy” (Nathan and Fang 2009:132) or even as a “social movement” (Dobrin and Berson 2011). A documentary perspective is here synthesized with an adult literacy one, fitted to the context of West Africa, to offer some guidelines for revitalization efforts.

Towards An Intellectual History Of Evolutionary Economics: Competition And Struggle Versus Cooperation And Mutual Aid, John B. Hall, Svetlana Kirdina-Chandler

Economics Faculty Publications and Presentations

Our inquiry considers the origins of Evolutionary Economics by reintroducing a debate that took place in Russia in the 19th and early 20th century. Responses to Charles Darwin’s The origin of Species are considered, especially critiques stressing Darwin’s emphasis upon competition and struggle in natural selection, that can be traced directly to Thomas Robert Malthus. Considering challenging contributions made by several Russian scholars, we place special emphasis upon Peter Kropotkin’s focus on cooperation and “mutual aid” in natural selection and evolution. We then speculate upon the commonality found in the evolutionary views advanced by Kropotkin and his American contemporary, Thorstein …

Occurrence And Phenology Of Polistine Wasps (Hymenoptera: Vespidae) In Southern Louisiana, Scott Nacko

LSU Master's Theses

Phylogenetic studies suggest that historically all paper wasps (Vespidae: Polistinae) in North America have tropical origins. However, paper wasps have adapted to thrive in temperate conditions. Subtropical and temperate climates allow for a study of adaptive traits which can be retained or lost within populations, and ultimately help elucidate the process of social wasp evolution. Additionally, species occurrence patterns can help us to understand partitioning and resource use within populations. We investigated the occurrence and phenology of each Polistine species found at four sites in southern Louisiana around Baton Rouge, and also examined the occurrence and behavior of a closely …

Ethnic Audiences In A Fragmented Media Era: Ethnic Audiences' Selective Exposure To Likeminded Media, Mingxiao Sui

LSU Doctoral Dissertations

The conventional wisdom that U.S. and ethnic media have distinctive effects on ethnic populations’ assimilation into the American society inspires two closely related questions: (1) how do English- and ethnic-language media differ in news content?, and (2) to what extent is ethnic audiences’ preference for English- versus ethnic-language media systematically biased such that they seek to use media congenial to their most salient ethnic identity? The first question is expected to provide insights into what ethnic audiences learn about the U.S. and their country of origin from distinct news outlets, and to explain whether and how U.S. and ethnic media …

Organizational Supports Used By Private Child And Family Serving Agencies To Facilitate Evidence Use: A Mixed Methods Study Protocol, Emmeline Chuang, Crystal Collins-Camargo, Bowen Mcbeath

School of Social Work Faculty Publications and Presentations

Background: Challenges to evidence use are well documented. Less well understood are the formal supports—e.g., technical infrastructure, inter-organizational relationships—organizations may put in place to help overcome these challenges. This study will identify supports for evidence use currently used by private child and family serving agencies delivering publicly funded behavioral health and/or human services; examine contextual, organizational, and managerial factors associated with use of such supports; and determine how identified supports affect evidence use by staff at multiple levels of the organization. Methods: We will use a sequential explanatory mixed methods design, with study activities occurring in two sequential phases: In …

Student-Perceived Quality Of Motivational Interviewing Training: A Factor-Analytic Study, Douglas Smith, Melinda Hohman, Stéphanie Wahab, Trevor Manthey

School of Social Work Faculty Publications and Presentations

Objective: This study developed and tested a student-report measure of motivational interviewing (MI) teaching quality called the Evaluation of Motivational Interviewing Teaching (EMIT) scale.

Method: Social work students (N = 297) receiving course content on motivational interviewing completed the EMIT, and exploratory factor analysis investigated whether theory-based dimensions of teaching emerged as EMIT subscales, including: interactivity/skill building, MI content coverage, modeling MI during teaching, trainee autonomy violation, and encouraging ongoing training in MI.

Results: Two subscales emerged representing MIconsistent (28 items, α = .92) and MI-inconsistent teaching practices (7 items, α = .73).

Conclusions: Although more …

Assessing State Efforts To Integrate Transportation, Land Use And Climate, Rebecca Lewis, Robert Zako

TREC Final Reports

Climate change is increasingly recognized as a threat to life on earth. “Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. Limiting climate change would require substantial and sustained reductions in greenhouse gas emissions” (International Panel on Climate Change, 2014, 8).

The transportation sector accounts for almost one-third of all greenhouse gas emissions (GHG) in the United States. Reducing GHG from transportation rests on the “three-legged stool” of improving vehicle efficiency, reducing the carbon content of fuels …

Cyberpdx: A Camp For Broadening Participation In Cybersecurity, Wu-Chang Feng, Robert Liebman, Lois Delcambre, Michael Mooradian Lupro, Tim Sheard, Scott Britell, Gerald W. Recktenwald

University Studies Faculty Publications and Presentations

With society’s increasing dependence on technology infrastructure, the importance of securing the computers, networks, data, and algorithms that run our digital and physical lives is becoming critical. To equip the next generation of citizens for the challenges ahead, an effort is underway to introduce security content early in a student’s academic career. It is important that these efforts broaden participation and increase diversity in the field. While many camps and curricula focus on introducing technical content and skills related to cybersecurity, such approaches can prematurely limit how students view career opportunities in the field, potentially limiting those who ultimately pursue …

Changing The Rules: A Guide For Youth And Young Adults With Mental Health Conditions Who Want To Change Policy, Nancy Koroloff, Barbara J. Friesen, Nicholas Buekea

School of Social Work Faculty Publications and Presentations

This guide provides information about policy and policy change in mental health and other human services for young adult groups who want to be

directly involved in policy change activities. Some of the many ways that young people can be involved in policy work include serving on advisory committees that consider areas where policy change is needed, participating on groups convened to review contract language about youth-related issues or serving on groups charged with developing rules and regulations to support recent policy change. A number of manuals or handbooks address these important roles, although few of them are specifically focused …

Oregon Guide To Health Care Partnerships: For Community-Based Organizations And Advocates Supporting Survivors Of Domestic Violence In Health Care Settings, Sarah H. Keefe, Christine Heyen, Anna Rockhill, Ericka Kimball

School of Social Work Faculty Publications and Presentations

Safer Futures is a practice and partnership model that benefits survivors of intimate partner violence. This model demonstrates how community-based, non-clinical domestic and sexual violence (D/SV) intervention advocates can better serve survivors of intimate partner violence (IPV) in partnership with health care providers. Such partnerships strengthen services for survivors of IPV in various health care settings including, but not limited to, public health departments, Federally Qualified Health Centers, primary care clinics, and hospitals.

Partnerships between advocates and health care providers improve IPV survivors’ access to health care, advocacy services, resources and support. The model works best when a health care …

To Badge Or Not To Badge? From “Yes” To “Never Again”, Emily Ford

Library Faculty and Staff Publications and Presentations

This opinion essay does not present badging best practices or a discussion of badging procedures. Rather, it presents my personal, theoretical views as to why I will not use badges again. Reflecting over the past three years, I have realized that our use of badges re-created and reinforced traditional powers structures in the classroom. I now view badges as a symptom of a systemic and insidious problem in higher education: neoliberalism.

The Distribution Of Talker Variability Impacts Infants’ Word Learning, Carolyn Quam, Sara Knight, Louann Gerken

Speech and Hearing Sciences Faculty Publications and Presentations

Infants struggle to apply earlier-demonstrated sound-discrimination abilities to later word learning, attending to non-constrastive acoustic dimensions (e.g., Hay et al., 2015), and not always to contrastive dimensions (e.g., Stager & Werker, 1997). One hint about the nature of infants’ difficulties comes from the observation that input from multiple talkers can improve word learning (Rost & McMurray, 2009). This may be because, when a single talker says both of the to-be-learned words, consistent talker’s-voice characteristics make the acoustics of the two words more overlapping (Apfelbaum & McMurray, 2011). Here, we test that notion. We taught 14-month-old infants two similar-sounding words in …

The Intersection Between Masculinity And Health Among Rural Immigrant Latino Men, Jason Daniel-Ulloa, Christina J. Sun, Scott D. Rhodes

OHSU-PSU School of Public Health Faculty Publications and Presentations

Latino men experience health disparities in STI/HIV, diabetes, hypertension, and cancer. Gender roles likely play a role in risk behaviors and outcomes; however, there has been little focus on masculinity in Latino men. We conducted 20 semi-structured interviews with Latino men living in North Carolina. The interviews, conducted by a trained bilingual/bicultural Latino male, prompted discussion around work, family, and stress. Four themes were identified: masculine roles of being a family provider and protector, sources of stress, family responsibility and interconnectedness to health, and coping mechanism. For Latino men, masculinity may have both positive and negative influences on health. For …

Rubrics As A Foundation For Assessing Student Competencies: One Public Administration Program’S Creative Exercise, Billie Sandberg, Kevin Kecskes

Public Administration Faculty Publications and Presentations

Since implementation of the Network of Schools of Public Policy, Affairs, and Administration (NASPAA) standards for accreditation in 2009, public administration programs have been developing programmatic competencies that reflect NASPAA’s universal standards. Likewise, myriad efforts have analyzed data related to student and program progress toward achievement of these competencies. This article adds to that conversation by recounting the approach to assessing competencies used in the Department of Public Administration at Portland State University. There, newly developed rubrics reflect each of the department’s 10 competencies to examine whether students are acquiring the desired knowledge and skills. This article discusses the development …

Changing The Rules: A Guide For Youth And Young Adults With Mental Health Conditions Who Want To Change Policy, Nancy Koroloff, Barbara J. Friesen, Nicholas Buekea

Regional Research Institute for Human Services

To some people, “policy” seems like a mysterious and perhaps boring topic, compared to the busyness and intensity of everyday life. However, a growing number of youth- and young adult-led groups have shown how policy issues can influence their choices and their lives in critical ways, and that they can have substantial influence on policy. Policies may be general, and apply to all people in society (e.g., traffic laws), or they may specifically focus on particular groups of people, such as people with a mental health condition or criminal record (e.g., policies about housing or employment). Organizations such as Youth …

Building A Paradise? On The Quest For The Optimal Human Habitat, Anu Besson

Contemporary Aesthetics (Journal Archive)

Do humans have a natural habitat? If yes, is it the original habitat of early hominids or the most optimal environment for today’s humans? Are these two the same thing and, if not, what does ‘optimal habitat’ mean? I examine the concept of the optimal habitat from four viewpoints: 1) paradise; 2) urban design based on environmental psychology; 3) favorite places; and 4) environment as an invitation for action. I conclude that an optimal habitat is not a collection of more or less fixed elements but an environment that can be experienced as a beneficial feedback loop based on and …

Experience, Knowledge, And Appreciation In The Implicit Aesthetics Of Weather Lore, Mădălina Diaconu

Contemporary Aesthetics (Journal Archive)

[1] Weather sayings are empirical rules for the prediction of weather and have been studied, so far, only by paremiologists and meteorologists. The author argues that they also present interest for environmental aesthetics, and that their aesthetic dimension is not confined to their stylistic qualities and versified form but is mainly based on the experience that underlies them. The analyses of weather lore in English, French, and German emphasize that this pre-modern, expert knowledge produced and still can bring enjoyment and, conversely, that the sources of this aesthetic enjoyment are to a large extent cognitive, even if not scientific by …

On The Front: Aesthetics Vs. Popular Arts And Mass Culture - Ii, Ken-Ichi Sasaki

Contemporary Aesthetics (Journal Archive)

The popular arts and mass culture represent our environment. The flood of their products reduces high art to minority status. This situation leads us to reconsider the privileged status of high art and the role of aesthetics as its theory, which is my main focus here. I take up three different cultural eras: early modern times, when the notions of art and aesthetics as a philosophical discipline were founded; our own day as the time of mass culture; and, lastly, the popular culture in the Edo period in Japan, the seventeenth to the mid-nineteenth centuries, which reflected different choices.

The Aesthetics Of Conversation: Dewey And Davidson, Kalle Puolakka

Contemporary Aesthetics (Journal Archive)

Conversation is one of the most mundane events of human life, yet the conversations we have can vary a lot. Some proceed only with great effort, while others engage us thoroughly. Drawing on Dewey’s aesthetics, this paper argues that the movement and rhythm of conversations can make them into genuine candidates for an aesthetic status. The key term of the paper is interaction. For Dewey, all experience, aesthetic experience included, is constituted by an interaction between humans and their environment. In his later philosophy of language, which is critical of conventionalist explanations of language, Davidson, in turn, offers a very …

Cardiometabolic Risk Factors, Metabolic Syndrome And Pre-Diabetes In Adolescents In The Sierra Region Of Ecuador, Sharon L. Casapulla, Cheryl A. Howe, Gabriela Rosero Mora, Darlene Berryman, Mario J. Grijalva, Edgar W. Rojas, Jay H. Shubrook

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Background: Excess weight (overweight and obesity) is the major modifiable risk factor for type 2 diabetes mellitus (T2DM) and other non-communicable diseases. However, excess weight may not be as predictive of diabetes risk as once thought. While excess weight and other obesity-related non-communicable diseases are of growing concern in low-middle income countries in Latin America, there is limited research on risk factors associated with T2DM in adolescents. This study investigated prevalence of overweight, obesity, prediabetes, diabetes and metabolic syndrome in adolescents in Ecuador.

Methods: A cross-sectional study was conducted with 433 adolescents from two schools in a small …

Meta Analysis Of Human Alzgene Database: Benefits And Limitations Of Using C. Elegans For The Study Of Alzheimer's Disease And Co-Morbid Conditions, Behrad Vahdati Nia, Christine Kang, Michelle G. Tran, Deborah Lee, Shin Murakami

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Human genome-wide association studies (GWAS) and linkage studies have identified 695 genes associated with Alzheimer's disease (AD), the vast majority of which are associated with late-onset AD. Although orthologs of these AD genes have been studied in several model species, orthologs in the nematode, Caenorhabditis elegans, remain incompletely identified, with orthologs to only 17 AD-related genes identified in the C. elegans database, WormBase. Therefore, we performed a comprehensive search for additional C. elegans orthologs of AD genes using well-established programs, including OrthoList, which utilizes four ontology prediction programs. We also validated 680 of the AD genes as a unique …

Visualizing Morphogenesis With The Processing Programming Language, Avik Patel, Amar Bains, Richard Millet, Tamira Elul

Faculty Publications & Research of the TUC College of Osteopathic Medicine

We used Processing, a visual artists’ programming language developed at MIT Media Lab, to simulate cellular mechanisms of morphogenesis – the generation of form and shape in embryonic tissues. Based on observations of in vivo time-lapse image sequences, we created animations of neural cell motility responsible for elongating the spinal cord, and of optic axon branching dynamics that establish primary visual connectivity. These visual models underscore the significance of the computational decomposition of cellular dynamics underlying morphogenesis.
