Rab35 Centered Membrane Trafficking Pathway Directs Apical Constriction During Drosophila Gastrulation, Hui Miao
Electronic Theses and Dissertations
Force generation in epithelial tissues is often pulsatile, with actomyosin networks generating high-tension contractile forces at the cell cortex before cyclically disassembling. This pulsed nature of cytoskeletal forces implies that there must be cellular processes to extract unidirectional changes that drive processive transformations in cell shape. During Drosophila melanogastergastrulation, the invagination of the prospective mesoderm is driven by the pulsed constriction of apical surfaces. Here, we address the mechanisms by which the irreversibility of pulsed events is achieved while also permitting uniform epithelial behaviors to emerge. We use MSD-based analyses to identify contractile steps and find that when a …
Game Changing Leadership: Developing A Student Athlete Leadership Identity Development Model, Sally Gates Parish
Game Changing Leadership: Developing A Student Athlete Leadership Identity Development Model, Sally Gates Parish
Electronic Theses and Dissertations
There are several theoretical models and approaches to define the leadership identity development of college students, however, none of these models adequately frame the specific leadership identity development of collegiate student athletes. The purpose of this grounded theory study is to develop a leadership model to address this gap by explaining the leadership values and behaviors unique to student athletes and to understand if their leadership experiences occur in a staged, scaffolded way. The research questions guiding this study are: What are the staged, scaffolded leadership identity development experiences of collegiate student athletes? What are the common leadership values and …
