The Effects Of Learning Environment Resources And Psycap On Student Burnout And Outcomes, Elisandra Rodriguez Moreno

Dissertations

This study examined links between learning environmental resources (i.e., social support and feedback environment), burnout, and student outcomes (i.e., satisfaction and academic performance) among 198 graduate healthcare students. The study also investigated whether Psychological Capital (PsyCap) moderated these relationships. Social support and feedback did not predict overall burnout, but both were significantly linked to the burnout dimensions, specifically: emotional exhaustion, depersonalization, and academic efficacy. PsyCap did not moderate most relationships, yet it was consistently associated with lower levels of burnout and higher satisfaction. One exception emerged—for social support and depersonalization, PsyCap served as a compensatory resource, where students with lower …

Universal Basic Income (UBI), a specific and actionable policy of government redistribution, is a promising method of economic inequality …

The Social Aesthetics Of Recognition, Italo Alves

Dissertations

The history of social philosophy is a history of suspicion toward the aesthetic (1). However, since we apprehend social reality fundamentally through its aesthetic appearances, an account is needed of how “the aesthetic” must enter the social-philosophical discourse, particularly in reconstructive models of social critique. I call this account “social aesthetics.” Social aesthetics illuminates how certain social experiences generate normative claims even in the lack of discursive articulation. (2) I argue that the philosophy of recognition, concerned with this relationship between social experience and normative claim-making, contains an unacknowledged aesthetic dimension, which I uncover through a critical reading of Axel …

The Beloved Disciple In Performance, Eric Christian Zito

Dissertations

This project aims to reconsider the Fourth Gospel’s Beloved Disciple from the standpoint of biblical performance criticism, an approach that takes seriously the likelihood that most first-century audiences would have encountered the Fourth Gospel by means of performance rather than private reading. The dissertation considers: 1) what difference the medium makes in a first-century reception of John’s Gospel, and 2) how early audiences would have been shaped by the discipleship model portrayed by the unnamed Beloved Disciple in a performance setting. Against the current of mainstream scholarship, I argue that the Beloved Disciple is a developing character who epitomizes Johannine …

Forgive As We Are Forgiven: Reframing A Trinitarian Model Of Forgiveness In A Post-Genocide Rwanda, Deogratias Mbonyumugenzi

Dissertations

This dissertation seeks to develop a theological model of forgiveness rooted in a relational conception of the Trinity. The central argument of this dissertation is that the model of forgiveness practiced in post-genocide Rwanda and the forgiveness modeled by Jesus, and testified to in the New Testament and developed in the Christian tradition, are good, but not sufficient to address the kind of trauma and human disrepair, as well as the devastation of communities, inflicted by genocide. Rather, a theology of forgiveness modeled on a relational conception of the Trinity and its practical implications for a Trinitarian ecclesiology and anthropology …
