During the last half-century, the distribution of golden jackals (Canis aureus) has rapidly increased throughout Europe. Today, golden jackals are thriving in human-dominated landscapes across Southeastern and Central Europe. Most studies on golden jackals have focused on large-scale distribution patterns; to date, little is known about the species’ fine-scale spatial ecology. In this study, we analyzed the movement behavior, space-use and resource selection of six golden jackals fitted with GPS-GSM collars in two study areas in Hungary and Serbia. Two of the jackals were a breeding pair. We found that home range size averaged 11.2 km² (90% …

Effects Of Translocation On Survival Of Nuisance Bears, Javan Bauder, D. Ruid, N. M. Roberts, B. Kohn, M. L. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

Effective mitigation of human–wildlife conflict should aim to reduce conflicts while also minimizing wildlife mortality. Translocation is often used to mitigate human–wildlife conflict but translocated individuals may have reduced survival, which could negatively affect population growth and social acceptance of translocation as a management tool. Yet, non-translocated nuisance individuals may also have low survival due to inherent risks associated with nuisance behavior. We used a 38-year dataset of 1233 marked and translocated nuisance American black bears (Ursus americanus) as a model system with which to evaluate the impacts of translocation on nuisance bear survival. We used multi-state mark-recapture models to …

Threading The Needle: How Humans Influence Predator–Prey Spatiotemporal Interactions In A Multiple-Predator System, Asia Murphy, Duane R. Diefenbach, Mark Ternent, Matt Lovallo, David Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Perceived predation risk and the resulting antipredator behaviour varies across space, time and predator identity. Communities with multiple predators that interact and differ in their use of space, time of activity and hunting mode create a complex landscape for prey to avoid predation. Anthropogenic presence and disturbance have the potential to shift interactions among predators and prey and the where and when encounters occur. We examined how white-tailed deer Odocoileus virginianus fawn spatiotemporal antipredator behaviour differed along an anthropogenic disturbance gradient that had black bears Ursus americanus, coyotes Canis latrans, bobcats Lynx rufus and humans present. We quantified (a) spatial …

Understanding And Assessing Construct Validity Of The Social Provisions Scale: Implications For Youth Development, Sarah Osmane, Mark Brennan, Patrick Dolan

Journal of Youth Development

Confirmatory factor analysis using structural equation modeling was used to measure the construct validity of the increasingly utilized social provisions scale. This scale was used to measure social support sources and types among a sample of 421 youth from 4 Pennsylvania schools. The youth were surveyed to determine their levels of social support and the relationship of social support to community and youth development capacities. Research findings indicated an acceptable model fit indices for the sources of the social support model. A lower fit for the types of social support was found. Overall, the analysis further verified the reliability and …

Gauging Informal Stem Youth Program Impact: A Conceptual Framework And A Measurement Instrument, Robert Tai, Ji Hoon Ryoo, Claire Mitchell, Xiaoqing Kong

Journal of Youth Development

STEM education programs are often formulated with a "hands-on activities" focus across a wide array of topics from robotics to rockets to ecology. Traditionally, the impact of these programs is based on surveys of youth on program-specific experiences or the youths’ interest and impressions of science in general. In this manuscript, we offer a new approach to analyzing science programming design and youth participant impact. The conceptual framework discussed here concentrates on the organization and analysis of common learning activities and instructional strategies. We establish instrument validity and reliability through an analysis of validity threats and pilot study results. We …

Cultivating Youth Affinity For College Within The Context Of Campus-Based Summer Camps, Barry Garst, Ryan Gagnon, Thomas Clanton, Jay Woodward

Journal of Youth Development

College and university-based (CUB) summer camps are a prominent pre-collegiate experience targeting middle and high school adolescents, which research suggests may enhance college aspirations and preparedness, develop academic knowledge and skills, and influence future career choices. This study examines factors that predict the relation between affinity for college, program engagement and support, college major selection, and social–emotional outcomes stemming from youth involvement in a CUB camp based on data collected from 641 middle and high school-aged youth who completed an online questionnaire on the last day of the CUB camp. The findings validated a 4-factor model comprised of college brand …

Silence Is Not An Option: Oral History Of Race In Youth Development Through The Words Of Esteemed Black Scholars, Keshia Harris, Corliss Outley

Journal of Youth Development

The study of race has been silenced in many areas of science including youth development research. We present this commentary in response to an invitation to address the impact of racism on the field of youth development for the Journal of Youth Development. Through oral history narratives, the paper synthesizes an antiracist agenda from the perspectives of 6 Black scholars: Tabbye Chavous, Michael Cunningham, Davido Dupree, Leoandra Onnie Rogers, Stephanie Rowley, and Robert Sellers. The narratives depict each scholar’s perspective on race research that informs youth-serving programs and the study of race in research of children and adolescents, particularly Black …

Pharmaceutical Potential Of Laboratory Grown Cultures Of Blue-Green Algae: A Comprehensive Review And Future Possibilities, Ritu Chauhan, Abhishek Chauhan, Ashutosh Tripathi, Anuj Ranjan, Subhash C. Chauhan, Tanu Jindal

School of Medicine Publications

COVID-19 pandemic has taught the world researchers the urgent need for new sources and novel pharmaceuticals not only for existing diseases but also for both seasonal epidemics and future pandemics. Pharmaceutical drug discoveries for the past fifty years depended deeply on the procedure of empirical transmission of a huge number of pure bioactive compounds to provide new leads. The screening of extracts or isolating compounds is a common way to discover novel biologically active molecules. Most of the valuable Blue-Green algal metabolites are concentrated in their biomass. For existence in nature, Blue-Green algae (BGA) secrete and contain various organic substances …

Replicability In Empirical Legal Research, Jason M. Chin, Kathryn Zeiler

Faculty Scholarship

As part of a broader methodological reform movement, scientists are increasingly interested in improving the replicability of their research. Replicability allows others to perform replications to explore potential errors and statistical issues that might call the original results into question. Little attention, however, has been paid to the state of replicability in the field of empirical legal research (ELR). Quality is especially important in this field because empirical legal researchers produce work that is regularly relied upon by courts and other legal bodies. In this review article, we summarize the current state of ELR relative to the broader movement towards …

Resolution Of Two Steps In Botulinum Neurotoxin Serotype A1 Light Chain Localization To The Intracellular Plasma Membrane, Alexander Gardner, William H. Tepp, Marite Bradshaw, Joseph T. Barbieri, Sabine Pellett

College of Nursing Faculty Research and Publications

Botulinum neurotoxin serotype A (BoNT/A) is the most potent protein toxin to humans. BoNT/A light chain (LC/A) cleavage of the membrane-bound SNAP-25 has been well-characterized, but how LC/A traffics to the plasma membrane to target SNAP-25 is unknown. Of the eight BoNT/A subtypes (A1–A8), LC/A3 has a unique short duration of action and low potency that correlate to the intracellular steady state of LC/A, where LC/A1 is associated with the plasma membrane and LC/A3 is present in the cytosol. Steady-state and live imaging of LC/A3-A1 chimeras identified a two-step process where the LC/A N terminus bound intracellular vesicles, which facilitated …

A Visual Tour Of Carbon Export By Sinking Particles, Colleen A. Durkin, Ken O. Buesseler, Ivona Cetinić, Margaret L. Estapa, Roger P. Kelly, Melissa Omand

Graduate School of Oceanography Faculty Publications

To better quantify the ocean's biological carbon pump, we resolved the diversity of sinking particles that transport carbon into the ocean's interior, their contribution to carbon export, and their attenuation with depth. Sinking particles collected in sediment trap gel layers from four distinct ocean ecosystems were imaged, measured, and classified. The size and identity of particles was used to model their contribution to particulate organic carbon (POC) flux. Measured POC fluxes were reasonably predicted by particle images. Nine particle types were identified, and most of the compositional variability was driven by the relative contribution of aggregates, long cylindrical fecal pellets, …

Gender Deviants: Subverting Regulatory Power In Medical Institutions, Ursa Nuffer-Rodriguez Mx.

University Honors Theses

Medical and psychiatric institutions have a long history of regulating and pathologizing the bodies of non-normative individuals. The harmful normativity of these institutions is particularly salient for trans* people pursuing gender-affirming medical care, as popular media representations of trans* identity reinforce narratives of certainty and aspirations towards cisgender standards of corporeality which rarely map onto authentic narratives of trans*ness. For the gender deviant subject, who conceives of hirself beyond these hegemonic notions of identity, navigating these institutions often requires a false projection of identity that fits the standard narrative, simply as a means to an end. In doing so, the …

Plastic-Eating Microbes: A New Potential Solution To Waste Mitigation?, Megan Forbes

University Honors Theses

Plastic waste is problematic for marine and terrestrial ecosystems due to the mass production of polyethylene terephthalate (PET) single use plastics. What is unclear is a well-thought-out solution to solve pollution problems that will not further damage the environment. Throughout this literature review, I will investigate the role microbes play in plastic degradation, and if plastic eating microbes are an effective solution to the plastic pollution problem. Polyethylene terephthalate (PET) is the chemical name for polyester. It is a clear, strong, and lightweight plastic that is typically used for food and beverage packaging, and other single-use purposes. The most well …

Effects Of Hormone Replacement Therapy (Hrt) On Gene Expression In The Amyloid Processing Pathway Of Ovariectomized Rhesus Macaque Females Under An Obesogenic Diet, Megan Ball

University Honors Theses

Estrogens rapidly decline at the onset of menopause, putting women at higher risk of osteoporosis, obesity, and neurodegenerative diseases, including Alzheimer’s disease (AD). Estradiol hormone therapies (HT) have been suggested to limit these negative effects on women, with controversial findings as to their effectiveness. A study at OHSU recently found differentially expressed genes (DEGs) using RNAseq between ovariectomized/hysterectomized (OvH) old (range = 19.4–23.2 years) female rhesus macaques on HT and those on a placebo on chronic western style diet (WSD). The DEGs identified in the amyloid processing pathway of the amygdala were selected for validation using RT-qPCR because β-amyloid peptide …

Rice is a staple food and primary source of calories for much of the world. However, rice can be a dietary source of toxic metal(loid)s to humans, and its cultivation creates atmospheric greenhouse gas emissions and requires high water use. Because rice production consumes a significant amount of natural resources and is a large part of the global agricultural economy, increasing its sustainability could have substantial societal benefits. There are opportunities for more sustainable field production through a combination of silicon (Si) management and conservation irrigation practices. As a Si-rich soil amendment, rice husks can limit arsenic and cadmium uptake, …

Cats Teach Stats: An Interactive Module To Help Reduce Anxiety When Learning Statistics In Biology, Suann Yang, Jenny Hazlehurst, Darcy A. A. Taniguchi

Biology

Tools that teach quantitative skills and foster positive student attitudes toward these skills are important in biology curricula. Math and statistics anxiety is common and can interfere with student learning in biology courses. We describe a new framework for alleviating this anxiety. In our module, students watch a cute internet cat video, which inspires them to ask scientific questions about animal behavior and collect, analyze, and interpret data. We developed two freely available interactive tools to implement our module. We successfully implemented these tools with undergraduate students at two institutions. Based on this experience, we provide ideas for extension along …

Purpose: Rare genetic variants in KDR, encoding the vascular endothelial growth factor receptor 2 (VEGFR2), have been reported in patients with tetralogy of Fallot (TOF). However, their role in disease causality and pathogenesis remains unclear.

Methods: We conducted exome sequencing in a familial case of TOF and large-scale genetic studies, including burden testing, in >1,500 patients with TOF. We studied gene-targeted mice and conducted cell-based assays to explore the role of KDR genetic variation in the etiology of TOF.

Results: Exome sequencing in a family with two siblings affected by TOF revealed biallelic missense variants in KDR. Studies in knock-in …

Analysis Of Tri-Lineage Collagen Reporter Mice Growth Plates Through Light Sheet Microscopy, Olivia Ferrigno

Holster Scholar Projects

The growth plate is an active area of cartilage in the long bones of children. Its main function is to enable limb lengthening, but is a relatively weak structure that is prone to fractures and injuries. These injuries can have severe long term ramifications, as they can create premature bone fusion, also known as a bony bridge, that causes stunted or crooked growth. Dr. Liisa Kuhn’s Lab has developed an accurate, reproducible animal model that mimics this same growth plate behavior and can be used to further analyze the growth plate structure, healing process, and new treatments. This animal model …

The Citation Of Unpublished Cases In The Wake Of Covid-19, Michael L. Smith

Chapman Law Review

California’s Rules of Court prohibit the citation of unpublished state court opinions. Courts and litigants, however, may still cite unpublished federal opinions and rulings and unpublished opinions from other states’ courts. This may result in problems, such as limiting courts’ and parties’ authorities to a skewed sample set, and the covert importation of inapplicable, stricter federal court pleading standards in state court cases.

COVID-19 was a stress-test that brought the problems with California’s citation rules into focus. The pandemic led to a flood of claims for pandemic-related business interruptions by insured business owners against their insurance companies. While state courts …

Articles, Book Chapters, & Popular Press

There are several nature-based adaptation options available to coastal nations. In this paper, we offer a brief overview of these options and then focus on mangroves to consider how laws and policies can support nature-based solutions and thereby contribute to more effective overall adaptation efforts. We first outline the concept of adaptation and its variants, thereby setting the context for this study. We then briefly explore the science relating to nature-based adaptation. We analyze the international legal regime in place to protect mangrove ecosystems. Finally, we discuss the merits, the challenges, and strategies developed to surmount some of the challenges …

Soliton Based All-Optical Data Processing In Waveguides, Amaria Javed

Dissertations

The growing demand for higher data processing speed and capacity motivates the replacement of the current electronic data processing by optical data processing in analogy with the successful replacement of electronic data communication by optical data communication. In a quest to achieve comprehensive optical data processing we aim at using solitons in waveguide arrays to perform all-optical data processing operations. Solitons are special nonlinear waves appreciated for their ability to conserve their shape and velocity before and after scattering. They are observed naturally in diverse fields of science, namely, nonlinear physics, mathematics, hydrodynamics, biophysics, and quantum field theory, etc. with …

Disability Without Documentation, Katherine A. Macfarlane

Fordham Law Review

Disability exists regardless of whether a doctor has confirmed its existence. Yet in the American workplace, employees are not disabled, or entitled to reasonable accommodations, until a doctor says so. This Article challenges the assumption that requests for reasonable accommodations must be supported by medical proof of disability. It proposes an accommodation process that accepts individuals’ assessments of their disabilities and defers to their accommodation preferences. A documentation-free model is not alien to employment law. In evaluating religious accommodations, employers—and courts—take a hands-off approach to employees’ representations that their religious beliefs are sincere. Disability deserves the same deference. This Article …

Aixfood'21: 3rd Workshop On Aixfood, Ricardo Guerrero, Michael Spranger, Shuqiang Jiang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Food and cooking analysis present exciting research and application challenges for modern AI systems, particularly in the context of multimodal data such as images or video. A meal that appears in a food image is a product of a complex progression of cooking stages, often described in the accompanying textual recipe form. In the cooking process, individual ingredients change their physical properties, become combined with other food components, all to produce a final, yet highly variable, appearance of the meal. Recognizing food items or meals on a plate from images or videos, their physical properties such as the amount, nutritional …
