Currere As Contemporary Art: Weaving Creative Research, Purposeful Vulnerability, And Poetic Expression To Nurture Teacher Self-Knowledge, Kimberley D'Adamo

Kimberley D'Adamo: Art, Curriculum, Publications, and Other Scholarly Works

Statement, first paragraph:

Pinar’s currere process offers educators supports for engaging in honest self-reflection to develop liberatory practices and tools to facilitate purposeful vulnerability. Currere scaffolds a transformative journey, enabling educators to explore their educational past, interpret it in their current context, and use those personal and pedagogical insights to envision alternative educational futures. In many ways, currere is about identifying and developing one’s own authentic voice, which appeals to me as both an educator and artist.

From Mind Only To Buddha Only: Shakya Chokden’S Interpretation Of Tathāgatagarbha In Tantric Philosophy And Practice, Yaroslav Komarovski

Department of Classics and Religious Studies: Faculty Publications

Shakya Chokden’s approach consists of reducing all phenomena to mind and its appearances, and then negating dualistic minds as illusory and nonexistent and establishing the non-dual jñāna transcending them as the only phenomenon existent in reality—the primordial tathāgatagarbha with all buddha-qualities complete. For him, this interpretation of tathāgatagarbha is indispensable for tantric contemplative practice and for explaining how and why that practice works. The initial identification of tathāgatagarbha as the primordially existent jñāna endowed with buddha-qualities serves as the foundation for conceptually envisioning deities of the ultimate body-maṇḍala and eventually, when enough clarity is achieved, directly perceiving them by jñāna …

Supervisor Integrity Empowers Employees To Advocate For Diversity In Problematic Climates, Timothy G. Kundro, Brett H. Neely Jr., Cindy P. Muir (Zapata)

Department of Management: Faculty Publications

Supervisors struggle to encourage employees to engage in diversity advocacy—key behaviors that help promote more equitable workplaces. Research hints that one reason for this struggle may be that employees lack the empowerment to engage in such behaviors. Drawing on perspectives that conceptualize diversity advocacy as a moral and virtuous behavior, we integrate research on leadership and empowerment to suggest that supervisor integrity can empower observers to engage in diversity advocacy. In exploring boundary conditions, we draw on performance models to counterintuitively suggest that this effect is strongest when employees perceive a negative diversity climate, as employees see the greatest need …

Methodologizing Transnationality: Relational Writing As Collective Inquiry, Sun Young Lee, Minhye Son, Taeyeon Kim, Jin Kyeong Jung, Soo Bin Jang

Department of Educational Administration: Faculty Publications

How can we take transnationality as a space of in-betweenness to generate new possibilities, moving beyond geographically bounded spans between countries? This article presents five authors’ collective inquiry on transnational positionalities, which we practiced through the relational, transformative, and reflective writing of the self in a community space. We staged the collaborative writing into two processes: the emergent process of thematic writing and the relay writing. Interweaving “I” and “we” voices that cannot be captured through categorical thinking, our collaborative quest resists normative identity politics, proposing writing as a method of collective inquiry for the nuanced understanding of the transnationality …

Navigating Emotional Discomfort In Developing Equity-Driven School Leaders: A Conceptual-Pedagogical Framework, Taeyeon Kim, James Wright

Department of Educational Administration: Faculty Publications

Abstract

Background: Given that K–12 schools necessitate leaders who can advance equity and justice, preparation programs in higher education institutions have prioritized the development of eq-uity-oriented school leaders. However, there has been relatively limited exploration of peda-gogical approaches that equip educational leaders to navigate adverse emotional responses and utilize their discomforting emotions as a source of transformation toward equity-oriented principles. When negative emotions are suppressed and/or unexplored within leadership de-velopment programs, adult learners will likely miss crucial opportunities for personal growth and transformative change.

Purpose: This theoretical article aims to enhance and expand existing scholarship on the ped-agogies …

Medical Expenditures And The Measurement Of Poverty In The United States, Luke Petach, David Wyant

Faculty Scholarship

Using data from the Medical Expenditure Panel Survey (MEPS) we estimate the fraction of the US population that is health poor. A person is health poor if their income prior to paying health insurance premiums and out-of-pocket healthcare costs is above the poverty line, but their income net-of-premiums and out-of-pocket healthcare costs is below the poverty line. Because resources used to finance health insurance premiums and out-of-pocket costs are (A) lexicographically preferred and (B) cannot be used to maintain an individual’s standard of living, they should be excluded from official poverty estimates. Approximately 1% to 2% of the US population …

A Proposal For The Use Of A Fixed Low-Energy Selective Laser Trabeculoplasty For Open Angle Glaucoma, Zachary Sacks, L. Jay Katz, Gus Gazzard, Sarah H. Van Tassel, Eytan Z. Blumenthal, Fabian S. Lerner, Augusto Azuara-Blanco, Gregory John Roy Spooner, Yoram Solberg, Thomas Samuelson, Michael Belkin

Wills Eye Hospital Papers

Selective laser trabeculoplasty (SLT) has been in routine clinical use for over 20 years with millions of patients successfully treated and a low rate of clinically significant complications. The procedure requires the clinician to manually position the laser beam on the trabecular meshwork using a gonioscopy lens and to titrate the SLT laser energy based on the amount of pigmentation in the angle, as well as the observation of small bubbles produced by the laser effect. We propose that SLT energy titration is unnecessary either to achieve intraocular pressure (IOP) reduction or to minimize potential side effects. Ample evidence to …
