Introducing "Visual Bibliographies" As A Novel Tool For Communicating Complexity: A Knowledge Translation Case Study From Aboriginal And Torres Strait Islander Primary Health Care Research, Kathleen P. Conte, Alison Laycock, Jodie Bailie, Veronica Matthews, Ross Bailie

Homelessness Research & Action Collaborative Publications and Presentations

Background

Effective knowledge translation ensures health care research has desired impacts – this is particularly important for Indigenous communities who have historically not benefited from research about and on them. Yet much knowledge translation in Indigenous contexts continues without community partnerships and disregards Indigenous values, languages and knowledge-sharing practices. Visual approaches can be engaging knowledge translation strategies that align with Indigenous knowledge translation traditions and amplify Indigenous perspectives. In this paper, we introduce a new tool we have coined a “Visual Bibliography” for knowledge generation and translation, developed within a large-scale, participatory research collaboration in Aboriginal and Torres Strait Islander …

Review Of Bootstrap Applications, Joshua Russell

Electronic Theses and Dissertations Archive

We investigate the bootstrap methodology and current applications. The bootstrap is a non-parametric resampling method that has universal applicability thanks to the statistical concepts of weak convergence, the law of large numbers, and the central limit theorem. Modern applications of bootstrap methodology have demonstrated time and time again that it is computationally efficient and robust. The earliest days of the bootstrap saw it validated by generating statistics, confidence intervals, and hypothesis tests. It is important to note the universal application and efficiency of the bootstrap, especially when researchers are tempted to utilize the more financially and computationally expensive techniques of …

The Educational Leadership Trajectories Of Black Gay Males: A Narrative Inquiry, Abidemi Omowale Kayode

Student Theses and Dissertations

This qualitative study examines the educational leadership trajectories of Black gay men (BGM) working in K-12 public schools. These BGM navigate identity-centered marginalization from school systems. Their leadership development is shaped by structural barriers, exclusive frameworks, and cultural expectations whether visible or invisible. This study addresses the scant literature in educational leadership around intersecting racial and sexual identities, and how this omission contributes to exclusionary and discriminatory trauma for BGM. These inequities are supported by heteronormative adult cultures, interpersonal dynamics, and policy. The consequences of these inequities are both political and professional as well as psychologically harmful and deeply personal. …

Perceptions Of Mentoring Relationships And Novice Teacher Self-Efficacy And Attrition, Renee Dunwoody

Student Theses and Dissertations

A study of over 400 new Level 1 licensed teachers in New Mexico found that mentorship relationships directly correlate to a teacher's self-efficacy and their likelihood of leaving the profession. The study surveyed traditionally trained and alternative licensure teachers employed in New Mexico and in their first 3 years of teaching. The results revealed that teachers who had high-quality relationships with their mentors, as scored on the Leader- Member Exchange 7 Questionnaire, had a stronger belief in their own self-efficacy and were less likely to consider leaving the teaching profession. In contrast, teachers who rated their mentors highly on the …
