Critically Examining The Experiences Of Queer People Of Color In Culturally-Based Sororities And Fraternities, Antonio Duran, Crystal Eufemia Garcia, Hannah Lee Reyes

Department of Educational Administration: Faculty Publications

Guided by Queer of Color critique as a theoretical framework, this research project investigated the experiences of Queer People of Color in culturally-based sororities and fraternities (CBSFs). Engaging in a secondary analysis of two critical narrative inquiry studies (one focused on Queer Men of Color and the other on Queer Women of Color), we examined how systems of power and oppression manifested across CBSFs. In addition, we interrogated how Queer People of Color practiced agency when faced with oppressive settings. Findings revealed the politics of disclosure given anti-Black histories and religious origins of organizations, the different ways organizations regulated gender …

Owning Educational Change In Korean Schools: Three Driving Forces Behind Sustainable Change (Excerpt), International Education News, Taeyeon Kim, Minseok Yang, Sunbin Lim

Department of Educational Administration: Faculty Publications

“Can the innovative educational changes imposed by the pandemic be sus-tained for the long-term?” That’s the question that Taeyeon Kim, Minseok Yang, and Sunbin Lim ask in the third commentary in a series launched by Corrie Stone-Johnson and the Journal of Educational Change. This question builds on the first commentary in that series by Yong Zhao and Jim Watterston – “The changes we need post-Covid” and the sec-ond “What can change in schools after the pandemic?” by Thomas Hatch. This week’s post provides an excerpt from the third commentary, highlight-ing they key lessons and implications from the pandemic experiences of …

Owning Educational Change In Korean Schools: Three Driving Forces Behind Sustainable Change, Taeyeon Kim, Minseok Yang, Sunbin Lim

Department of Educational Administration: Faculty Publications

In this essay, we discuss how the COVID-19 pandemic drove key changes in schooling and what forces can sustain these changes. Responding to the argument that COVID-19-driven changes may not be sustainable, this essay offers a counter narrative from the Korean context, in which educators re-visited existing school systems and re-constructed policies and teaching practices to fill the educational vacuum caused by the pandemic. This essay specifically builds on interviews conducted with Korean educators throughout the 2020 school year during COVID-19. First, we discuss ownership of educational change as reflected in educators’ narratives. We then explore three driving forces behind …

Social Connectedness And Negative Affect Uniquely Explain Individual Differences In Response To Emotional Ambiguity, Maital Neta, Rebecca L. Brock

Department of Mechanical and Materials Engineering: Faculty Publications

Negativity bias is not only central to mood and anxiety disorders, but can powerfully impact our decision-making across domains (e.g., financial, medical, social). This project builds on previous work examining negativity bias using dual-valence ambiguity. Specifically, although some facial expressions have a relatively clear negative (angry) or positive valence (happy), surprised expressions are interpreted negatively by some and positively by others, providing insight into one’s valence bias. Here, we examine putative sources of variability that distinguish individuals with a more negative versus positive valence bias using structural equation modeling. Our model reveals that one’s propensity toward negativity (operationalized as temperamental …

Vision, Challenges And Opportunities For A Plant Cell Atlas, Plant Cell Atlas Consortium, Suryatapa Ghosh Jha, Marc Libault, David W. Ehrhardt, Seung Y. Rhee, 32 Other Scientists

Department of Agronomy and Horticulture: Faculty Publications

With growing populations and pressing environmental problems, future economies will be increasingly plant-based. Now is the time to reimagine plant science as a critical component of fundamental science, agriculture, environmental stewardship, energy, technology and healthcare. This effort requires a conceptual and technological framework to identify and map all cell types, and to comprehensively annotate the localization and organization of molecules at cellular and tissue levels. This framework, called the Plant Cell Atlas (PCA), will be critical for understanding and engineering plant development, physiology and environmental responses. A workshop was convened to discuss the purpose and utility of such an initiative, …

Current Market Rates For Scholarly Publishing Services, Alexander Grossman, Björn Brembs

Copyright, Fair Use, Scholarly Communication, etc.

For decades, the supra-inflation increase of subscription prices for scholarly journals has concerned scholarly institutions. After years of fruitless efforts to solve this “serials crisis”, open access has been proposed as the latest potential solution. However, the prices for open access publishing are also high and are rising well beyond inflation. What has been missing from the public discussion so far is a quantitative approach to determine the actual costs of efficiently publishing a scholarly article using state-of-the-art technologies, such that informed decisions can be made as to appropriate price levels. Here we provide a granular, step-by-step calculation of the …

Understanding Tolerance For An Invasive Species: An Investigation Of Hunter Acceptance Capacity For Wild Pigs (Sus Scrofa) In Texas, Hailey E. Mclean, Tara L. Teel, Alan Bright, Lauren M. Jaebker, John M. Tomecek, Maureen G. Frank, Rachael L. Connally, Stephanie A. Shwiff, Keith M. Carlisle

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive species and their establishment in new areas have significant impacts on the ecological, economic, and social well-being of our planet. Wild pigs (Sus scrofa) are one of the world’s most formidable invasive species, particularly in the United States. They cause significant damage to agriculture and ecosystems, and can transmit diseases to livestock, wildlife, and people. There is an inherent social dimension to the issue of wild pigs due in part to the fact that people hunt them. Hunting contributes to both the control and spread of this species. The objectives of this study were to: 1) determine hunters’ overall …

Landscape Use By Fishers (Pekania Pennanti): Core Areas Differ In Habitat Than The Entire Home Range, Jennifer R. Kordosky, Eric M. Gese, Craig M. Thompson, Patricia A. Terletzky, Kathryn L. Purcell, Jon D. Schneiderman

United States Department of Agriculture Wildlife Services: Staff Publications

Home ranges have long been studied in animal ecology. Core areas may be used at a greater proportion than the rest of the home range, implying the core contains dependable resources. The Pacific fisher (Pekania pennanti (Erxleben, 1777)) is a rare mesocarnivore occupying a small area in the Sierra Nevada Mountains, California, USA. Once statewide, fishers declined in the 1900s due to trapping, habitat fragmentation, and development. Recently, drought induced by climate change may be affecting this population. We examined space use of fishers in their core versus their home range for levels of anthropogenic modifications (housing density, road density, …

The Consequences Of Predators Without Prey, Mitchell A. Parsons, Thomas M. Newsome, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Rapid and ongoing environmental change is leading to scenarios where marine and terrestrial predators are persisting without prey, either by scavenging or using anthropogenic foods. Despite investigations into the effects of predator presence or absence on prey behavior and ecology, little research has assessed the effect of prey absence on predators. Here, we synthesize research on scavenging and the use of anthropogenic resources by marine and terrestrial predators; hypothesize how the use of these resources may change predator behavior with respect to their social structure, space use, life history, and individual behavioral traits; and illustrate how these changes are likely …

Social Identity And Acceptability Of Wild Pig (Sus Scrofa) Control Actions: A Case Study Of Texas Hunters, Lauren Jaebker, Tara L. Teel, Alan D. Bright, Hailey E. Mclean, John M. Tomeček, Maureen G. Frank, Rachael L. Connally, Stephanie A. Shwiff, Keith M. Carlisle

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) pose significant challenges to wildlife managers. This research explored Texas hunters’ acceptability of wild pig control actions, and whether acceptability varied according to hunters’ affiliation with four different categories of natural resource organizations as an indicator of social identity. Results of a survey (n = 37,317) revealed that most hunters were accepting of all control actions except toxicants and non-lethal deterrents. Mean acceptability scores for each action differed significantly across the four affiliation categories, but effect sizes were minimal. Hunters affiliated with agricultural organizations were the most accepting of control actions, while hunters with …

Social Media As A Window Into Human-Wildlife Interactions And Zoonotic Disease Risk: An Examination Of Wild Pig Hunting Videos On Youtube, Hailey E. Mclean, Lauren M. Jaebker, Aaron M. Anderson, Tara L. Teel, Alan D. Bright, Stephanie A. Shwiff, Keith M. Carlisle

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) damage agriculture and the environment, as well as transmit diseases to animals and people. Hunters are particularly vulnerable to zoonotic disease risks when harvesting wild pigs. Management agencies have endeavored to inform the public about disease risks associated with wild pigs and best practices for mitigating such risks. However, the extent that this guidance has reached hunters and influenced their practices is unclear. We approached this topic through an analysis of wild pig hunting videos on YouTube. We found evidence of relatively few behaviors and communications regarding disease risks and best practices for personal …

Relative Acceptance Of Brodifacoum Pellets And Soft Bait Sachets By Polynesian Rats (Rattus Exulans) On Wake Atoll, Peter J. Kappes, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

Removing invasive rats from island ecosystems using rodenticides has proven conservation benefits and is an important management tool for conserving and restoring island ecosystems. However, rodenticide-based eradications can fail if not all rats consume enough bait to result in lethal toxicosis. A recent post-operational review of a failed attempt to eradicate rats from Wake Atoll suggested that some individuals may not have ingested a lethal dose of rodenticide due to potential dietary and/or sensory preferences developed via regular access to anthropogenic food sources. These food sources may be higher in fats and oils, possessing different sensory properties (e.g., softer, chewier, …

Differing Alterations Of Odor Volatiles Among Pathogenic Stimuli, Patrick Millet, Talia Martin, Maryanne Opiekun, Gary K. Beauchamp, Bruce A. Kimball

United States Department of Agriculture Wildlife Services: Staff Publications

Alterations of the volatile metabolome (the collection of volatiles present in secretions and other emanations) that occur in response to inflammation can be detected by conspecifics and chemometric analyses. Using a model system where mouse urinary metabolites are altered by treatment with lipopolysaccharide (found in the outer cell membrane of gram-negative bacteria), we hypothesized that alteration of body odor volatiles will vary according to the pathogen responsible for inducing the inflammation. We tested this hypothesis by treating mice with different immunogens that engage different immune signaling pathways. Results suggest that alterations of body odor volatiles resulting from inflammation do contain …

Reference Checks, Tara Myers, Megan Paul

Umbrella Summaries

What are reference checks?

Reference checks are hiring tools, typically used as one of the last steps in the hiring process. “A reference check generally involves contacting applicants’ former employers, supervisors, coworkers, and educators to verify previous employment and to obtain information about the individual’s knowledge, skills, abilities and character” (Society for Human Resource Management, 2020, p. 1). For example, potential employers use this as an opportunity to get additional information about applicants’ job performance, communication, time management, teamwork, professionalism; honesty; and attention to detail (Hendricks, Rupayana, Puchalski, & Robie, 2018). The questions used on reference checks depend on the …

Brain Α-Tocopherol Concentration Is Inversely Associated With Neurofibrillary Tangle Counts In Brain Regions Affected In Earlier Braak Stages: A Cross-Sectional Finding In The Oldest Old, J. Tanprasertsuk, T.M. Scott, M.A. Johnson, L.W. Poon, P.T. Nelson, A. Davey, J.L. Woodard, R. Vishwanathan, A.K. Barbey, K. Barger, X.-D. Wang, E.J. Johnson

Department of Nutrition and Health Sciences: Faculty Publications

Objectives: Higher vitamin E status has been associated with lower risk of Alzheimer’s disease (AD). However, evidence of the association of vitamin E concentration in neural tissue with AD pathologies is limited. Design: The cross-sectional relationship between the human brain concentrations of α- and γ-tocopherol and the severity of AD pathologies – neurofibrillary tangle (NFT) and neuritic plaque (NP) – was investigated. Setting & Participants: Brains from 43 centenarians (≥ 98 years at death) enrolled in the Phase III of the Georgia Centenarian Study were collected at autopsy. Measurements: Brain α- and γ-tocopherol concentrations (previously reported) …

Building Capacity To Effectively Share And Use Data, Robert Blagg

Other QIC-WD Products

In child welfare, the need to utilize meaningful data to ensure that the services provided are effective in supporting children and families represents a continuing challenge. There is a large volume of data from sources that are internal and external to child welfare agencies; and it increases almost exponentially on a regular basis. It is difficult for leaders and practitioners to quickly and meaningfully synthesize, make use of, and share new information with colleagues who need it to make sound decisions. Even when data is transformed into knowledge, challenges remain around the preferred method of ensuring information reaches the individuals …

Occupational Commitment, Megan Paul, Anita Barbee

Umbrella Summaries

What is occupational commitment?

Occupational commitment refers to the extent to which employees are committed to their line of work (Meyer, Allen, & Smith, 1993). Over the past 40 years, various researchers also labeled the construct as career commitment or as professional commitment, but the term occupation is intended to convey that the concept (a) does not apply to a more general concept of a career, which may involve different occupations over time and (b) applies to both professional and non-professional occupations (Meyer et al., 1993). Occupational commitment is one of many forms of work-related commitment. Some of the other, …

More Research Is Needed On The Impact Of Workplace Violence, Bullying And Sexual Harassment In Child Welfare, Anita Barbee

Other QIC-WD Products

Many employees working in social services are exposed to workplace violence (described in Andersen, et al., 2018) and bullying (discussed in Whitaker, 2012). The workplace violence paper showed not only that up to three-fourths of social workers are exposed to violence at work, but that organizational structures and dynamics set the stage for violence to occur. Settings where staff lacked role clarity and predictability, and where emotional demands, role conflict, and work family conflict were high, also were associated with more threats and violence among employees and by clients. These findings, in addition to studies on bullying, seem to point …

Food System Resilience In Nigeria: Farmers Perspective, Azariah Lawal

School of Natural Resources: Dissertations, Theses, and Student Research

Disturbances are inherent in every socio-ecological system (SES). However, the spate and scope of upheavals in contemporary SES has increased dramatically in recent years. Agricultural systems are perhaps the most impacted when disasters occur because different aspects of agricultural production are directly affected. The burgeoning farmers-Fulani herdsmen conflict in West Africa is a manifestation of these challenges. When faced with events like these, contemporary food systems are faced with two options: collapse or transform. It is essential to have resilient agricultural systems because these systems lie at the nexus of resolving emerging global issues.

Nigeria is an important country in …

A Qualitative Study Exploring Attachment Through The Context Of Indian Boarding Schools, Melissa D. Olson (Zephier)

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This is a qualitative phenomenological exploration looking at how Indian boarding schools impacted Indigenous families and indicators of how their attachment was affected. Thirty-one semi-structured interviews were conducted with 18 individuals who attended Indian boarding schools and 13 descendants of those who attended these schools. The interviews were conducted on a Northern Plains reservation where approval was obtained from that tribal college and the University of Nebraska-Lincoln. Results indicate knowledge sharers in both groups, individuals who attended boarding schools and those who descended from these individuals experienced critical impacts to their ability to form intergenerational attachments with subsequent generations due …

Open Access: “Information Wants To Be Free”?, Richard Poynder

Copyright, Fair Use, Scholarly Communication, etc.

The main points made in this document:

- Internet mantras like information wants to be free misled OA advocates about what is possible in an online world. Amongst other things, these mantras led to the mistaken belief that publishing would be very much cheaper on the internet.

- BOAI was intended to achieve three things: to resolve the longstanding problems of affordability, accessibility, and equity that have long dogged scholarly communication.

- It now seems unlikely that the affordability and equity problems will be resolved, which will impact disproportionately negatively on those in the Global South. And if the geopolitical …

Influence Of Convenience, Time-Savings, Price, And Product Variety On Amazon Prime Members And Non-Prime Shoppers’ Online Apparel Purchase Intention, Md Rashaduzzaman

Department of Textiles, Merchandising and Fashion Design: Dissertations, Theses, and Student Research

The number of internet users and online shoppers in the United States has grown at an incredible rate over the past few decades. Greater convenience and availability of a wide assortment of apparel products at a cheaper price made online shopping very enticing to consumers. Amazon.com (Amazon) gained unprecedented popularity among consumers with its Amazon Prime program. Amazon’s retail revolutions changed consumer’s way of shopping and expectations. Both online and physical store retailers are facing tremendous pressure to fulfill that level of expectation. Thus, it is essential for retailers clearly understand the shopping expectations and preferences of Amazon Prime members …

Reyes, Sahra H. Ali, Kimberly Gocchi Carrasco, Patrick Habecker, Kristen Houska, Virginia Chaidez, Jordan Soliz, Julie A. Tippens, Kathryn Holland, Lisa M. Pytlikzillig, Kali Patterson, Kirk Dombrowski

Department of Communication Studies: Faculty Publications

Community-based participatory research (CBPR) has been shown to improve health and social well-being by including diverse, marginalized community voices within academic–community partnerships. Although CBPR has gained in popularity, an explicit examination and evaluation of communication processes and outcomes throughout an entire CBPR project is lacking. Here, we analyze interviews with 10 stakeholders (i.e. 4 academic and 6 community partners) about their experiences in a three-phase, mixed-methods project exploring Hispanic and Somali community members’ perceptions of healthcare needs and access in a rural U.S. community. Results reflect that CBPR endeavors include communication challenges, successes, and ongoing tensions not simply between the …

Most of these tests are not available in any package. Thus, doex is easy to use for researchers in multidisciplinary studies. In this study, an extensive Monte-Carlo simulation study is conducted to investigate the performance of the the tests for equality of normal distributed group means …

Packet Delivery: An Investigation Of Educational Video Games For Computer Science Education, Robert Lafferty

School of Computing: Dissertations, Theses, and Student Research

The field of educational video games has rapidly grown since the 1970s, mostly producing video games to teach core education concepts such as mathematics, natural science, and English. Recently, various research groups have developed educational games to address elective topics such as finance and health. Educational video games often target grade school audiences and rarely target high school students, college students, or adults. Computer science topics are not a common theme among educational video games; the games that address Computer Science topics teach computer fundamentals, such as typing or basic programming, to young audiences.

Packet Delivery, an educational video …

Effects Of Career Courses On Career Self-Efficacy And Outcome Expectations, Celeste Spier

Department of Educational Administration: Dissertations, Theses, and Student Research

The purpose of this study was to examine two required career courses to determine if they produced an increase in career self-efficacy and outcome expectations, and which components of the learning theory from Social Cognitive Career Theory have the strongest influence. Participants were undergraduate business students at a midsized, Midwestern university enrolled in two required career courses and a comparison group of students not yet enrolled in the courses. Students took four measures (i.e., Career Exploration and Decisional Self-Efficacy Scale, Career Search Self-Efficacy Scale, Career Expectations Survey Scale, and Career Exploration and Decision Learning Experiences Scale) at two points in …

The Role Of Faculty In Fostering Psychosocial Wellbeing Among University Students, Kelley Wick

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The transition to college represents a major life event, and successfully navigating this shift has implications for students’ psychosocial wellbeing. While there is ample support for the idea that social relationships can facilitate student wellbeing during the transition to college, there is limited understanding of the unique role faculty may play in supporting students. The aim of this study was to determine the relation of faculty support to student wellbeing and self-efficacy, independent of peer support and student level of stress. Additionally, the primary questions were to examine whether self-efficacy mediated the relation of faculty support to student wellbeing, and …

Relationship Between Personal Distress And Aggression Is Moderated By Nucleus Accumbens Volume, Yuan Ta Poh

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Studies into the relationship between empathy and aggression has found that the effect is weak (Vachon et al., 2014). This weak relationship is observed through aspects of empathy interacting with aspects of aggression in different ways depending on the types of empathy and aggression being measured. The present study utilized neuroimaging approach to examine the relationship among empathy, aggression and nucleus accumbens (NAc) volume. Forty nine college students underwent magnetic resonance imaging scans and completed the Interpersonal Reactivity Index as well as the Reactive-Proactive Questionnaire. Using FreeSurfer, bilateral NAc volumes were obtained for statistical analysis. Hierarchal regression analyses were utilized …
