Puppy Dog Eyes: Begging For Treats And The Regulation Of Dog Breeding, Abigail Barford

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

In this note, Abigail Barford explores the lack of regulation over dog breeding in Kentucky, particularly the harms caused by puppy mills and backyard breeders. Barford explains that loopholes in the Animal Welfare Act and Kentucky’s absence of state-level protections contribute to dog overpopulation, inhumane conditions, environmental damage, and financial burdens on taxpayers. Barford argues for Kentucky to adopt strong breeding regulations modeled on Pennsylvania’s laws and its own equine breeding system. She proposes statewide legislation to license breeders, enforce humane standards of care, and regulate small-scale breeding to curb overpopulation and protect animal welfare.

We Know The Odds Aren't Ever In Our Favor: Toward An Understanding Of White Privilege Deprivation Amongst Black Individuals And The Initial Validation Of The White Privilege Deprivation Scale, Jennifer Burris

Theses and Dissertations--Educational, School, and Counseling Psychology

Social science scholarship acknowledges that disparities affecting Black people in the United States are rooted in historical race-based oppression (Black & Stone, 2005; Borell, Barnes, & McCreanor, 2018; Harrell, 2000; Mills, 1997). Yet little is understood about the ways Black people psychologically experience being denied the social privileges conferred upon Whites (i.e., White privilege). The belief that White privilege exists, along with the perceptions that Black people as a group are systematically deprived of benefits conferred upon Whites, could expose Black people to negative psychological and psychosocial experiences. As such, White privilege deprivation (the belief one is denied the social …

Examining The Psychometric Properties Of The Classroom Whiteness Scale (Claws) Through Rasch Partial Credit Analysis, Jaylene T. Patterson

Theses and Dissertations--Educational, School, and Counseling Psychology

This pilot study examines how whiteness manifests in K-12 classrooms by developing and evaluating the Classroom Whiteness Scale (ClaWS), an instrument designed to assess in-service teachers’ salience and engagement with whiteness-informed practices. ClaWS consists of 21 items across two subscales: one measuring the salience of whiteness-related beliefs in teachers’ pedagogical decisions and the other capturing the frequency of these practices in classroom settings. Rooted in critical whiteness studies, the scale operationalizes key dimensions of whiteness, including ethnocentric monoculturalism, white standardization, white silence, right to comfort, white saviorism, and colorblind racial ideology.

Using Rasch Partial Credit Model (RPCM) analysis, this study …

“A Safe Place”: Exploring Black Couples’ Perceptions Of Black Love And Relationship Coping In The Context Of Their Lived Experiences With Racism, Melinda Murdock

Theses and Dissertations--Family Sciences

Historically, Black couples have not been studied within the context of their lived experiences as it relates to the effects of racism on relationship health. Only in the last decade have relationship scholars begun to consistently link racism-related stressors to relationship processes and outcomes. Despite the growing literature, recent studies are primarily quantitative in method and rely on samples, theoretical models, and measures that predominantly represent White couples’ experiences. It remains unclear how Black couples’ perceptions of love and relationship coping lead to resilient outcomes despite the negative effects of racism.

Therefore, the goal of the present study is to …

Voltage And Var Control And Real-Time Digital Simulator-Based Protection System Testing For Power Distribution Systems, Gaurav Yadav

Theses and Dissertations--Electrical and Computer Engineering

Rising power demand calls for electric distribution systems to manage peak load. One option is reducing feeder voltage, which lowers voltage-dependent load demand and may also reduce energy usage. The technique, known as Conservation Voltage Reduction (CVR), may operate independently or within a volt/var control system. This dissertation examines CVR factor calculation using measurements collected at the substation, and proposes a curve-fitting and artificial neural network method to estimate active power losses using input active power, reactive power, and substation voltage. As utilities integrate more inverter-based resources (IBRs) to support increasing demand, rapid voltage fluctuations arise due to the intermittent …

Ex Vivo Single-Molecule Analysis Of Ryanodine Receptor 2 Assembly In Cardiac And Neuronal Tissue, Qianye Yin, Christopher I. Richards

Chemistry Faculty Publications

Understanding receptor assembly is critical for elucidating the mechanisms underlying their function and regulation in physiological processes. While traditional in vitro single-molecule studies rely on isolating proteins from heterologous expression systems, they often fail to capture the in vivo physiological complexity involved in the organization and assembly of cell surface proteins. This protocol employs Total Internal Reflection Fluorescence Microscopy (TIRFM) to study GFP-tagged Ryanodine Receptor 2 (RyR2) molecules encapsulated within nanoscale vesicles. These vesicles, generated from organs rapidly extracted from the animal, effectively provide a snapshot of the receptor's assembly state at the time of extraction, enabling detailed analysis of …

New Insights Into The Ovulatory Process In The Human Ovary, Misung Jo, Mats Brännström, James W. Akins, Thomas E. Curry

UK CARES Faculty Publications

BACKGROUND: Successful ovulation is essential for natural conception and fertility. Defects in the ovulatory process are associated with various conditions of infertility or subfertility in women. However, our understanding of the intra-ovarian biochemical mechanisms underlying this process in women has lagged compared to our understanding of animal models. This has been largely due to the limited availability of human ovarian samples that can be used to examine changes across the ovulatory period and delineate the underlying cellular/molecular mechanisms in women. Despite this challenge, steady progress has been made to improve our knowledge of the ovulatory process in women by: (i) …
