Domestic Violence Against Men: Their Report Decision Making Process, Ngozi Aleke

Electronic Theses and Dissertations

Little or nothing is really known about a man’s victimization in a domestic violence situation. Generally domestic violence is viewed from the lens of a women with the typical idea that women are the victim while men, the perpetrators of violence. Overtime, this societal perception is beginning to subside as researchers have proven that men are also victims of domestic violence (Straus, Gelles, & Steinmetz,1980). Despite this revelation, not much is known about male victimization as most men prefer not to report their victimization. This study seeks to examine the reasons for not reporting victimization and the effect of this …

A Psychometric Analysis Of The Comprehensive School Survey (Css) Middle School Student Version., Stephen Leach

Electronic Theses and Dissertations

School climate is increasingly recognized by scholars and policymakers as a crucial factor associated with students’ educational experiences. Hence, practitioners endeavor to equitably measure and improve school climate to promote favorable student academic and behavior outcomes. Unfortunately, school climate research is fragmented, and a research-practice gap exists in best scale development and validity testing practices. The result is a proliferation of practitioner-developed school climate measures lacking solid theory-grounding and evidence to support intended score interpretations and uses. In response, Whitehouse et al. (2021) proposed a validity testing framework for practitioner-developed instruments aimed at supporting culturally responsive school climate measurement. Their …

Stigma Described By Attempt Survivors With Diverse Gender And Sexual Identities In Their Suicide Stories: A Hermeneutic Phenomenological Dissertation., Sara Williams

Electronic Theses and Dissertations

Suicide is a profoundly impactful issue across societies. Gender and sexually diverse (GSD) populations exhibit rates of suicidal ideation and behavior far greater than those of cisgender heterosexual populations. Stigma impacts health outcomes among GSD populations through stress exposure and response processes. Compound stigma is experienced when individuals occupy positions in multiple stigmatized identity groups and can have multiplicative effects on adverse outcomes. Further, opportunities for positive social support and resilience building may be limited due to the narrow convergence of stigmatized identity groups. Stigma among GSD suicide attempt survivors (GSDAS) is an important phenomenon to explore in order to …

'Bleeding-In-The-World': A Qualitative Study Of Self-Cutting And Blood, Sadie Mohler

Electronic Theses and Dissertations

This dissertation is an existential, phenomenological study of the role and meaning of blood in self-cutting. Using in-depth, open-ended interviews with participants who self-cut, the author gathered data on the multisensorial experience of blood and bleeding in self-cutting. Data analysis was organized around the lifeworld existentials of corporeality, temporality, spatiality, communication, and relationality. The impact of blood and bleeding across each lifeworld dimension emphasized highly relevant, and previously unstudied, aspects of the lived experience of self-cutting. The six themes identified and explored are (a) blood as an animate abject; (b) bleeding and control; (c) bleeding is a process and the …

Rendering Documentary Portraiture: An Interrogation Of Archival Discourse Through A Critical Exploration Of Nineteenth Century Stage Actress Charlotte Cushman’S Material Memory, Skyler Sunday

Electronic Theses and Dissertations

Visual depictions of nineteenth century stage actress Charlotte Cushman, such as photographs, engravings, and painted portraits assist researchers in re-envisioning her both as an actress and as a person, but what do her remaining archival possessions further reveal to researchers about her memory? How do different objects operate as portraits that allow the researcher to tap into and remember specific moments and memory? How does the effort to preserve memory take different forms? This project argues that, when viewing the archive through its stored objects, our collective notion of portraiture can be expanded and used to interrogate existing methods of …

My first aim investigated between species differences by studying the bioactive properties of salamander skin peptides against Bsal and the related pathogen, B. dendrobatidis (Bd). Skin peptides were collected from five salamander species, used for in vitro assays, and analyzed by RP-HPLC. While skin peptides from one …

Ethical Oversight Of Roles & Relationships In Treatment & Research In Advanced Disease States, Alexa Vercelli

Electronic Theses and Dissertations

There is often ethical analysis focusing solely on the care of the patient by the physician or on the protection of the research participant by the clinical investigator, but those two are often overlapping. By paralleling the analysis of treatment and research, it emphasizes the specific ethical approaches necessary for individuals facing advanced diseases states in the separate roles of being a patient or participant. It also gives guidance to the complexity of the ethics surrounding medical professionals who float between the roles of treating physicians and clinical investigators. As individuals with advanced disease states are considered a vulnerable population …

Novel Signal Sequences And Fusion Partners For Paratransgenesis In Asaia, Christina Grogan

Electronic Theses and Dissertations

Mosquitoes transmit many pathogens that cause human disease. One such disease, malaria, is caused by parasites in the genus Plasmodium, infecting over 200 million people and killing over 600,000 per year. Current strategies to control vector-transmitted diseases are increasingly undermined by mosquito and pathogen resistance. Research has turned to additional and novel methods of control, such as altering the microbiota of the vectors. In this method, called paratransgenesis, symbiotic bacteria are genetically modified to affect the mosquito’s phenotype by engineering them to deliver antiplasmodial molecules into the midgut to kill parasites. These molecules must be released by the …
