Using Data In The Classroom To Drive Instructional Design And Delivery, L E. Eberman, J P. Young
Clinical Practice in Athletic Training
Introduction: Roughly half of ATP program directors include education on transgender health care in their programs, and even fewer report having the competence to do so. However, professional-level accreditation standards (56, 57, and DEI 2) require that programs have faculty with contemporary expertise to educate students on these outcomes. Current research suggests a comprehensive transgender and sexual health curriculum, including safe-zone training, traditional lecture, lab, and project-based instruction, was partially effective at changing students’ attitudes toward transgender patients but did not improve sexual health care delivery during a standardized patient encounter. The purpose of this project was to evaluate the …

Traveling The Pathway To A Culturally Competent Health Care Provider: Incorporating Study Abroad Into Your Curriculum, A L. Johnston Green, C J. Heffner
Clinical Practice in Athletic Training
Introduction: As athletic training employment settings expand and diversify, so does the patient population with whom these healthcare providers interact. This growth furthers the need to ensure that students enrolled in an athletic training program (ATP) accredited by the Commission on Accreditation of Athletic Training Education (CAATE) are educated to provide culturally competent care. Culturally competent care is provided when decisions made diminish the inequalities that may be present in a system based upon a patient’s individual circumstances. Implementing cultural competency education may be integrated into athletic training education in various manners as necessitated by each institution’s unique circumstances. Programs …

Exploring The Work-Related Quality Of Life Of Athletic Trainers In Physician Practice, N T. Anderson, K E. Games, J P. Young, M J. Rivera, L E. Eberman
Clinical Practice in Athletic Training
Introduction/Context: The National Athletic Trainers’ Association (NATA) identified the vitality of the athletic training profession as a research priority, which includes exploring solutions to improve work-life balance. There is a common perception that athletic trainers (AT) working in the physician practice setting have lower work-life conflict and increased job satisfaction, but no data to support this belief. Work-Related Quality of Life (WRQoL) has been studied in some healthcare settings but has not been studied in any athletic training clinical practice setting. Therefore, the purpose of this study is to investigate the WRQoL of athletic trainers in physician practice. Methods: A …
How Do Athletic Trainers Impact Patient Health Literacy?: A Critically Appraised Topic, T Bouchard
How Do Athletic Trainers Impact Patient Health Literacy?: A Critically Appraised Topic, T Bouchard
Clinical Practice in Athletic Training
Introduction/Context: Health Literacy is defined as “the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.” An estimated 80 million Americans are estimated to have low levels of health literacy. Low health literacy has been linked to poor patient outcomes and decreased usage of health services. Athletic trainers are multiskilled medical professionals recognized by the American Medical Association, trained in, among other things, wellness promotion and education, injury prevention and rehabilitation, and primary care. Although athletic trainers have traditionally been employed in collegiate/elite sports, many are …

Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Animal Sentience
Carolyn Ristau’s trilogy provides a comprehensive account of Donald Griffin’s life and work, with the third volume focusing on cognitive ethology. This commentary focuses primarily on my own interactions with Don, particularly during my sabbatical at Rockefeller University when his campaign for cognitive ethology was gaining momentum. I recount my research on reptile behavior and cognition, my collaboration with Don and others at RU, and my role in advancing his ideas while contextualizing them within 19th-century comparative psychology. I also discuss developments in cognitive ethology, including critical anthropomorphism, the challenges of integrating subjective experience into behavioral science, and Griffin’s lasting …

Other Perspectives On Animals, Their Sentience And Cognition, Joyce M. D'Silva Mrs
Animal Sentience
For those of us who work to achieve legal recognition that animals are sentient beings, and should in many cases be allotted personhood, Donald Griffin is indeed an inspiration and a true game-changer. He put paid to the narrow behaviourist interpretation of animals’ lives promoted by Skinner et al. He became a real heir to Darwin’s belief in animal emotions. He enabled campaigners for animal welfare and indeed animal rights to quote his work as a distinguished scientist to give gravitas to their calls for legal recognition and protection of animals.

An Individuals-Oriented Approach To Conservation, Kristy M. Ferraro
Animal Sentience
Individual cognitive and emotional differences in personality among animals, along with differences in their behavioral traits, are increasingly important in conservation efforts. It is not only more effective but more ethical to take both collective and individual perspectives into account in both research and practice.
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
Animal Sentience
For many animal species, the ability to adapt to coexistence with the human species and to the environmental changes that humans cause is a biological imperative. This adaptive capacity varies not only between species, but within species. Studying individual differences in animals’ behavioral, cognitive and physiological adaptability is important for integrating ethology and conservation. Findings about animal cognitive capacities, including learning, need to be applied in conservation—but humans need to be educated about ethology, coexistence and conservation too.

Position statement: The International Society of Sports Nutrition (ISSN) provides an objective and critical review of the use of a ketogenic diet in healthy exercising adults, with a focus on exercise performance and body composition. However, this review does not address the use of exogenous ketone supplements. The following points summarize the position of the ISSN: 1. A ketogenic diet induces a state of nutritional ketosis, which is generally defined as serum ketone levels above 0.5 mM. While many factors can impact what amount of daily carbohydrate intake will result in these levels, a broad guideline is a daily dietary …

Protein supplementation often refers to increasing the intake of this particular macronutrient through dietary supplements in the form of powders, ready-to-drink shakes, and bars. The primary purpose of protein supplementation is to augment dietary protein intake, aiding individuals in meeting their protein requirements, especially when it may be challenging to do so through regular food (i.e. chicken, beef, fish, pork, etc.) sources alone. A large body of evidence shows that protein has an important role in exercising and sedentary individuals. A PubMed search of “protein and exercise performance” reveals thousands of publications. Despite the considerable volume of evidence, it is …

Evaluation Of The Impact Of Urban Stream Syndrome On Macroinvertebrate Functional Feeding Diversity And Organic Matter Processing In Streams, Helena Loucas
Longwood Senior Thesis Proposal
The relationship between macroinvertebrate functional diversity and environmental processes is connected in streams. Aquatic macroinvertebrates are specialized feeders, falling into five functional feeding groups which affect processes such as the decomposition of organic matter. Urbanization causes the degradation of streams in a process is known as the Urban Stream Syndrome, and can result in increased concentrations of contaminants, altered stream morphology, and reduced taxonomic richness. The reduction of taxonomic richness increases the abundance of tolerant species, altering functional feeding groups, which will affect ecosystem processes within the stream. My proposed study seeks to determine the effects of urbanization on ecosystem …

Aborted Confidentiality, Stacey A. Tovino
Faculty Articles
As the number of abortion-restricting laws continues to grow in the wake of the Supreme Court’s ruling in Dobbs v. Jackson Women’s Health Organization, law enforcement officers are increasingly interested in obtaining and using reproductive health information for law enforcement purposes. Although physicians and other covered entities generally are required to keep protected health information (PHI) confidential under the Health Insurance Portability and Accountability Act Privacy Rule, a number of regulatory exceptions historically have permitted covered entities to disclose PHI for civil, criminal, and administrative investigations and proceedings. On April 26, 2024, the Department of Health and Human Services …

Background
We estimated the predictive value of rectal (bacterial sexually transmitted infection [bSTI]) pathogen detection for future HIV seroconversion among young adult sexual and gender minorities (YSGMs) assigned male at birth (AMAB).
Methods
Data were collected between March 2018 and August 2022 from RADAR, a longitudinal cohort study of YSGMs AMAB living in the Chicago metropolitan area (n = 1022). Rates of rectal bSTIs and the proportion of self-reported rectal bSTI symptoms are reported. We examined whether the presence of rectal bSTIs predicted HIV seroconversion using generalized estimating equations (GEEs).
Results
Participants tested reactive for rectal Mycoplasma genitalium (MGen), Neisseria …

Statistics Used In The Nebraska Beef Reports And Their Purpose, University Of Nebraska-Lincoln
Nebraska Beef Cattle Reports
The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore he/she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description of …

Effect Of Biochar On Enteric Methane Production And Cattle Performance, Hanna Cronk, Holly Heil, Rebecca Mcdermott, Mitch Norman, Galen E. Erickson, Andrea Watson
Nebraska Beef Cattle Reports
Methane is a more potent greenhouse gas than carbon dioxide. Because ruminant animals, including cattle, emit methane, strategies are actively being sought to reduce these emissions. Pistachio shell-sourced biochar was included at 0.5% of a finishing cattle diet to determine effects on methane emissions and cattle performance. Eight pens of cattle were rotated through a 2-chambered emissions barn to analyze methane and carbon dioxide produced by the cattle. Biochar tended to increase methane emissions on a g/d basis with no effect on methane emissions as g/lb of feed intake and no differences in carbon dioxide emissions. There were no differences …

Impact Of Strip-Grazing Stockpiled Annual/Cover Crop Forages On Carrying Capacity And Animal Performance, Shelby L. Davies-Jenkins, Abigail Sartin, Devin Jakub, Zac Carlson, Erin Laborie, Jack Arterburn, Ben Beckman, Brad Schnick, M. E. Drewnoski
Nebraska Beef Cattle Reports
Annual forages/cover crops can be used to fill the fall/winter grazing gap, and strip grazing may increase carrying capacity by reducing trampling losses of the forage. The current experiment utilized a series of on-farm experiments across two growing seasons to compare continuous and strip grazing of various summer planted cover crops. Strip grazing increased carrying capacity by an average of 47 ± 15% and gain per acre by 44 ± 5% compared to continuous grazing although significant variability in the amount of increase was observed. This variability can likely be attributed to forage type (quality), frequency of moves, and forage …

Infrequent supplementation saves labor and may reduce animal performance, but recent research with reduced fat distillers grains has provided inconsistent results. This experiment evaluated the effects of daily and three times a week supplementation of dried distillers grains on yearling steer performance grazing smooth bromegrass pastures from May to August. Daily supplemented steers received 5.6 pounds of dry matter per steer of dried distillers grains with solubles 7 days/week. The three times a week supplemented steers received 13.0 pounds of dry matter per steer of dried distillers grains with solubles three days/week (Monday, Wednesday, Friday). A control treatment received no …

Effect Of Methionine Supplementation During Late Gestation In Beef Females, Landon F. Tadich, Jim R. Teichert, Kathryn J. Hanford, Jacki A. Musgrave, Rich N. Funston
Nebraska Beef Cattle Reports
Some amino acids are known to be essential to cattle and effect protein availability to the animal, especially during gestation when nutrient requirements are higher. Methionine is found to be one of the most limiting in low quality forage diets. Two 3-yr studies were performed to evaluate the impact of methionine supplementation during late gestation on intake, body weight, average daily gain, and subsequent calf performance in primiparous and multiparous females. In exp 1, 120 artificially inseminated pregnancy heifers were placed in a Calan gate feeding system (n=40/yr) and assigned 1 of 3 treatments during late gestation and fed ad …

Biomedical Sciences
Genome-to-phenome research in agriculture aims to improve crops through in silico predictions. Genome-wide association study (GWAS) is potent in identifying genomic loci that underlie important traits. As a statistical method, increasing the sample quantity, data quality, or diversity of the GWAS dataset positively impacts GWAS power. For more precise breeding, concrete candidate genes with exact functional variants must be discovered. Many post-GWAS methods have been developed to narrow down the associated genomic regions and, ideally, to predict candidate genes and causative mutations (CMs). Historical natural selection and breeding-related artificial selection both act to change the frequencies of different alleles of …
Cultivating Access: The Benefits And Challenges Of Using Community Land Trusts To Preserve Farmland And Support Farmers., Meghan Daly
Graduate Student Theses, Dissertations, & Professional Papers
Agricultural land protected by community land trusts (CLTs) is more likely to remain in active production due to the CLT’s ability to enforce land use practices and select tenants committed to farming. While land tenure approaches vary among CLTs, protected agricultural lands typically utilize long-term leases with affordable rents (Ela and Rosenberg, 2020). Such leasing arrangements enable farmers to access land at prices unaffected by escalating land values (Schwartz et al., 2013). The CLT model not only safeguards farmland but also promotes active agricultural production, thereby ensuring local food supply and providing economic opportunities for farmers.
Despite the promising potential …

Changing climate, vegetation, and fire exclusion are altering and homogenizing fire-regime attributes compared to historic conditions. Fire-regime changes are commonly quantified using departure metrics, which are often based on measures of central tendency (i.e. changes in the mean). These metrics can mischaracterize complex changes to the distributional characteristics of fire-regime attributes. Here we develop a fire-regime departure metric that quantifies nonparametric distributional changes to fire-regime attributes over time. We use this metric to compare fire frequency and severity between historical (~1600-1880) and contemporary (1880- 2021) time periods in western US forests. Our analysis revealed that 89% of Western US forests …
