The Place Of Crossbred Lambs In Australian Lamb Production, David L. Hopkins, Suzanne I. Mortimer, Jessica S. Richards

IGC Proceedings (1997-2023)

The Australian sheep industry, particularly the lamb meat sector has undergone a major change in focus, such that consumer requirements are a paramount determinant for production and processing developments. This change has been facilitated by the use of cross breeding production systems where the benefits of heterosis are captured and the implementation of a performance recording system amongst initially, breeders of terminal sires. This sector of the industry has strongly embraced genetic selection using objectively measured traits and this is one of the contributors to the superior growth rate of crossbred progeny over pure bred progeny. A crossbreeding system does …

Characterizing Feeds And Feed Availability In Sud-Kivu Province, Dr Congo, Samy B. Bacigale, Birthe K. Paul, Fabrice L. Muhimuzi, Neville Mapenzi, Michael Peters, Brigitte L. Maass

IGC Proceedings (1997-2023)

Animal husbandry in the Sud-Kivu province of the Democratic Republic of the Congo (DRC) is gradually moving towards stall feeding, due to demographic pressure (Battistin et al. 2009) and scarcity of collectable forages (DSRP-RDC 2005). Therefore, feed is considered one of the main constraints faced by livestock production, especially in the dry season (Katunga et al. 2009; Maass et al. 2012). Unaffordable, fluctuating prices and inaccessibility of feed concentrates and the lack of improved forages adapted to marginal conditions, making them non-competitive with food crops, further exacerbate the livestock feeding situation. This study within the African Food …

Global Impacts From Improved Tropical Forages: A Meta-Analysis Revealing Overlooked Benefits And Costs, Evolving Values And New Priorities, Douglas S. White, Michael Peters, Peter Horne

IGC Proceedings (1997-2023)

The wider use and improved performance of planted tropical forages can substantially change social, economic and environmental landscapes. By reviewing impact-related studies published in the past two decades, this paper shows how evolving development priorities have influenced the types of impacts being documented. A meta-analysis was used to examine 98 studies according to: (1) breadth of reported effects, as related to development goals of social equity, economic growth and environmental sustainability; (2) extent of effects, ranging from intermediate to longer-term impacts; and (3) measurement precision (identification, description and quantification). Impacts have been assessed for fewer than half of the documented …

Introducing Phonetic Information To Speaker Embedding For Speaker Verification, Yi Liu, Liang He, Michael T. Johnson

Electrical and Computer Engineering Faculty Publications

Phonetic information is one of the most essential components of a speech signal, playing an important role for many speech processing tasks. However, it is difficult to integrate phonetic information into speaker verification systems since it occurs primarily at the frame level while speaker characteristics typically reside at the segment level. In deep neural network-based speaker verification, existing methods only apply phonetic information to the frame-wise trained speaker embeddings. To improve this weakness, this paper proposes phonetic adaptation and hybrid multi-task learning and further combines these into c-vector and simplified c-vector architectures. Experiments on National Institute of Standards and Technology …

Family Conflict Observations And Outcomes Among Adopted School-Age Children With Lesbian, Gay, And Heterosexual Parents, Rachel H. Farr, Samuel T. Bruun, Kyle A. Simon

Psychology Faculty Publications

Children’s externalizing problems are associated with family conflict among children and their biological parents, yet these linkages have remained unexamined among adoptive or lesbian and gay parent families. Investigating family processes facilitative of adjustment among adoptees, who face unique developmental challenges, is warranted. This multimethod study of 96 (26 lesbian, 29 gay, 41 heterosexual parent) adoptive families examined observations of adoptive family conflict and associations with child adjustment and feelings about adoption (children’s M_age = 8 years). The sample was recruited from 5 private, domestic infant adoption agencies across the United States. Parents and children reported about children’s externalizing …

Affect And Manhattan’S West Side Piers, Ricardo J. Millhouse

disClosure: A Journal of Social Theory

Derek P. McCormack (2010) argues, "Affect, is like an atmosphere: it might not be visible, but at any given point it might be sensed ... Emotion, in turn, can be understood as the sociocultural expression of this felt intensity" (643). This paper puts McCormack (2010) and Ben Anderson (2009) into conversation to think through the ways in which atmosphere in relation to affective and emotive life has been conceptualized. I center the affective atmospheres that happen with queer bodies that make New York's west side piers queerly affective. I use "queer bodies" to signal the dis-identification with heteronormativity or binaristic …

Volume 28: Affect, Robby Hardesty, Alina Hechler

disClosure: A Journal of Social Theory

The 2018-19 Editorial Collective is pleased to present the 28th volume of disClosure: A Journal of Social Theory. Our inspiration for this odd bundle of pages is rooted in the aesthetic of the self-printed zine. While we regret that we couldn't sneak into Miller Hall in the middle of the night to guerrilla-copy the entire issue on a late-80s black-and-white Xerox, we are proud to say that each page of this volume was assembled entirely by hand. Every page is bordered or backgrounded by collages: these are pages that peel and flake, assembled from bits and pieces cut up …

Feminist Friendship As An Affective Engagement Through The Arts: A Decolonial And Posthuman Becoming-With Rebeca Lane's Alma Mestiza, Miguel Ángel Blanco Martínez, Paola Mendoza Téllez-Girón

disClosure: A Journal of Social Theory

This paper considers friendship as an affective terrain of feminist alliance among subjects that belong to territories with a colonial record responding to the colonial/modern gender system (Lugones 2007) through the arts. Friendship is here conceptualized as an engagement of feminist solidarity unfolding within theoretical and practical models of change and resistance against the logics of cultural imperialism (Lugones and Spelman 1983). Turning friendship into a polyphonic feminist reaction, this work is conducted by acknowledging the need to foster dialogues where different authorial voices and feminist positionalities meet, reflect, and speak. The paper settles the encounter between its authors in …

Feel-Sad Tv: Sadness Pornography In Contemporary Serials, Blake K. Beaver

disClosure: A Journal of Social Theory

This article develops a theory of sadness pornographies in contemporary feel-sad television. Under the sad porn category, the essay explores a key sub-genre in contemporary serial dramas: trauma porn. The article is anchored in an affective analysis of two contemporary serials: Amazon's Transparent and NBC's This Is Us, both of which center multigenerational, familial trauma. Through a combined Berlantian and Spinozist optic, the essay attends to various episodes from the two serials to illuminate the phenomenon of trauma porn in current feel-sad media. In this reading, the essay considers how Spinoza's understandings of the temporality of affect relate to the …

Recovery After The Rupture: Linking Colonial Histories Of Displacement With Affective Objects And Memories, Aarzoo Singh

disClosure: A Journal of Social Theory

The notion of home and belonging, specifically in the context of South Asian postcolonial diasporas, is connected to past traumas of colonization and displacement. This paper addresses how trauma, displacement, and colonialism can be understood through and with material culture, and how familial objects and items emit and/ or carry within them, emotional narratives. I turn to the affective currency that emit and are transferred on and down from objects, by diasporic subjects, to access the possible reclamation of otherwise silenced narratives within colonial and postcolonial histories. By following the events of the Partition of India in 1947 as a …

Dispatches From Queer Potluck: [Extra]Ordinary Affects As A Project Of Belonging, Greg Niedt

disClosure: A Journal of Social Theory

This essay takes an approach that is part autobiography, part meditation on theory, in order to engage with the tension between "ordinary affects" (Stewart 2007) and the queer extraordinary. Drawing on my own experiences as part of an intentional community in Philadelphia, I consider what it means for me to experience affect in queer space. How does that manifest in the body, and the world in turn? How do these experiences fit into a larger desire for kinship and belonging? My purpose here is not to make broad claims about what affect is (or is not), but to provide a …

International R D & E Investment: Revitalising The Skill Base In Grassland Research And Practice, Ralph Von Kaufmann

IGC Proceedings (1997-2023)

Grasslands make up about 40.5% of the world’s land surface, and almost everywhere they make vital contributions to food supplies, livelihoods, watersheds, conservation of biodiversity and to ameliorating climate change through carbon sequestration. However, grasslands are under-represented in discussions on food security and livelihoods. Despite large investments in building human capacity, improving production systems and in research, grasslands are continuing to degrade and there is no let-up in sight for the consequent strife, famines and conflicts among the pastoral and other communities that depend on them. This review of grassland issues identified many critical skills that are lacking but it …

Feeding The World In 2050: Trade-Offs, Synergies And Tough Choices For The Livestock Sector, Jimmy Smith, Shirley Tarawali, Delia Grace, Keith Sones

IGC Proceedings (1997-2023)

Feeding the World in 2050 is a major challenge at the forefront of the global development agenda. The importance of agriculture in addressing this challenge has re-emerged in recent years as food security issues are considered in a more holistic manner. The role of livestock as part of the solution is, however, often not considered. This article presents a brief overview of the global food security challenge, and considers the increased focus on holistic food systems. It contends that animal agriculture is relevant to this complex, multifaceted and dynamic global challenge. However, if livestock-based solutions are to become a reality …

Interpreting Average Effect Sizes: Never A Center Without A Spread, Thomas R. Guskey

Educational, School, and Counseling Psychology Faculty Publications

School leaders today are making important decisions regarding education innovations based on published average effect sizes, even though few understand exactly how effect sizes are calculated or what they mean. This article explains how average effect sizes are determined in meta-analyses and the importance of including measures of variability with any average effect size. By considering the variation in effect sizes among studies of the same innovation, education leaders can make better decisions about innovations and greatly increase the likelihood of achieving optimal results from implementation.

General Education Learning Outcomes And Demographic Correlates In University Students In Hong Kong, Lu Yu, Daniel T. L. Shek, Xiaoqin Zhu

Pediatrics Faculty Publications

Although there are studies showing that higher education would benefit university students, empirical research that comprehensively assesses student general education learning outcomes and related demographic correlates based on longitudinal data is minimal, especially in the Chinese context. To address the research gaps, the present study was conducted to investigate learning outcomes amongst university students in one university in Hong Kong based on a four-year longitudinal design (N = 460). Four dimensions of student general education learning outcomes were measured, including effective reasoning and problem solving, leadership, moral character, and integration of learning. Results suggested a U-shaped pattern of student …

Hospital Closures And Short-Run Change In Ambulance Call Times, Sookti Chaudhary, Alison F. Davis, Kenneth R. Troske, Suzanne Troske

Rural & Underserved Health Research Center Publications

We measure one aspect of how access to emergency care through ambulance services changes for patients when a hospital closes. We empirically estimate the time needed to transport a patient to an emergency department in an ambulance in the period immediately after the hospital closes. We find urban patients in zip codes where a hospital closes have a small change in transportation time, where rural patients average an estimated 15.7 additional minutes – a 46% increase compared to the year before the closure. This increase is primarily the result of an almost 100 percent increase in the time it takes …

Turning Doctoral Students Into Faculty In Gerontological Social Work: The AgeSw Experience, Nancy Kusmaul, Stephanie P. Wladkowski, Sally Hageman, Allison Gibson, Rebecca L. Mauldin, Jennifer C. Greenfield, Noelle L. Fields

Social Work Faculty Publications

Developing faculty interested in aging may help social work meet the needs of our growing aging population. However, doctoral students need a variety of supports to complete PhDs and become gerontological social work faculty. This study explored one program’s role in supporting the development of social work doctoral students to faculty in gerontology. An e-mail invitation was sent to all former participants (2010–2016 cohorts) of the Association for Gerontology Education in Social Work (AGESW) Pre-Dissertation Fellows Program (PDFP). The 38-question online survey consisted of Likert-type scales, multiple answers, and one open-ended question per section about the program’s impacts on …

Trouble In The Tails? What We Know About Earnings Nonresponse 30 Years After Lillard, Smith, And Welch, Christopher R. Bollinger, Barry T. Hirsch, Charles M. Hokayem, James P. Ziliak

Economics Faculty Publications

Earnings nonresponse in household surveys is widespread, yet there is limited knowledge of how nonresponse biases earnings measures. We examine the consequences of nonresponse on earnings gaps and inequality using Current Population Survey individual records linked to administrative earnings data. The common assumption that earnings are missing at random is rejected. Nonresponse across the earnings distribution is U-shaped, highest in the left and right tails. Inequality measures differ between household and administrative data due in part to nonresponse. Nonresponse biases earnings differentials by race, gender, and education, particularly in the tails. Flexible copula-based models can account for nonrandom nonresponse.

Image Anaysis For Predicting Body Weight In Humans, Jeffrey S. Barrett, Chee Ng

Pharmaceutical Sciences Faculty Patents

Systems and methods for determining body weight predictions and human conditions are disclosed. A body weight may be predicted by capturing at least one image of a human, and determining, from the image, a body weight prediction of the human by processing the at least one image with a data processor. The body weight prediction may further be based on an age-based weight factor. A model such as a neural network model may be used to predict body weight.

Multiple Sclerosis Outcomes After Cancer Immunotherapy, Catherine R. Garcia, Rani Jayswal, Val R. Adams, Lowell B. Anthony, John L. Villano

Markey Cancer Center Faculty Publications

INTRODUCTION: Neurological immune-related adverse events are a rare but potentially deadly complication after immune checkpoint inhibitor (ICI) treatment. As multiple sclerosis (MS) is an immune-mediated disease, it is unknown how ICI treatment may affect outcomes.

METHODS: We analyzed the United States Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database for pembrolizumab, atezolizumab, nivolumab, ipilimumab, avelumab, and durvalumab 2 years prior their FDA approval until December 31, 2017, to include all cases with confirmed diagnosis/relapse of MS. We also included cases reported in the literature and a patient from our institution.

RESULTS: We identified 14 cases of MS …

Best Practice Recommendations For Replicating Experiments In Public Administration, Richard M. Walker, Gene A. Brewer, M. Jin Lee, Nicolai Petrovsky, Arjen Van Witteloostuijn

Public Policy and Administration Faculty Publications

Replication is an important mechanism through which broad lessons for theory and practice can be drawn in the applied interdisciplinary social science field of public administration. We suggest a common replication framework for public administration that is illustrated by experimental work in the field. Drawing on knowledge from other disciplines, together with our experience in replicating several experiments on topics such as decision making, organizational rules, and government–citizen relationships, we provide an overview of the replication process. We then distill this knowledge into seven decision points that offer a clear set of best practices on how to design and implement …

The Importance Of Shared Language In Rural Behavioral Health Interventions: An Exploratory Linguistic Analysis, Michele Staton, Jennifer Cramer, Robert Walker, Claire Snell-Rood, Athena Kheibari

Behavioral Science Faculty Publications

A focus on the use of shared language to enhance congruence in interventionist-client dialogue is missing from traditional research on evidence-based practices and rural behavioral health. This study incorporates qualitative interactional sociolinguistics, which includes discourse analysis (typically written or audio recordings of face-to-face encounters with 11 clients and a study interventionist), to describe those speech patterns in a broad sense (dialect), as well as more specific use of communicative strategies to increase parity in the interaction between a rural interventionist delivering an evidence-based practice in the context of a research study with rural women opioid users in a non-therapeutic context. …

BACKGROUND: Hospitalization-associated functional decline is a common problem for older adults, but it is unclear how hospitalizations affect physical performance measures such as gait speed. We sought to determine hospitalization-associated change in gait speed and likelihood of new limitations in mobility and activities of daily living (ADLs).

METHODS: We used longitudinal data over 5 years from the Health, Aging and Body Composition Study, a prospective cohort of black and white community-dwelling men and women, aged 70-79 years, who had no limitations in mobility (difficulty walking 1/4 mile or climbing 10 steps) or ADLs (transferring, bathing, dressing, and eating) at baseline. …
