A black Prometheus among the gods: illuminating African American literary tradition in Sam Greenlee\u27s The Spook Who Sat by the Door
Get PDFIn his hard-hitting novel The Spook Who Sat by the Door Sam Greenlee aims to help his target African American audience to succeed and thrive as their true selves with the novel functioning as a guide to resisting the ever-present physical and spiritual threat faced daily. On the one hand the novel functions as a manual for civil uprising, but underneath that surface, Greenlee argues that true African American resistance comes through nurturing self-determination, self-love, and self-esteem. This project also argues that Spook ought to be located closer to the center of the African American literary canon and provides comparisons to widely read and valued African American literature. This project argues for the canonization of The Spook Who Sat by the Door. This project claims that Greenlee views self-determination as a path to resistance and success for African Americans
The cell adhesion molecule Fasciclin2 regulates brush border length and organization in Drosophila renal tubules
Get PDFMulticellular organisms rely on cell adhesion molecules to coordinate cell–cell interactions, and to provide navigational cues during tissue formation. In Drosophila, Fasciclin 2 (Fas2) has been intensively studied due to its role in nervous system development and maintenance; yet, Fas2 is most abundantly expressed in the adult renal (Malpighian) tubule rather than in neuronal tissues. The role Fas2 serves in this epithelium is unknown. Here we show that Fas2 is essential to brush border maintenance in renal tubules of Drosophila. Fas2 is dynamically expressed during tubule morphogenesis, localizing to the brush border whenever the tissue is transport competent. Genetic manipulations of Fas2 expression levels impact on both microvilli length and organization, which in turn dramatically affect stimulated rates of fluid secretion by the tissue. Consequently, we demonstrate a radically different role for this well-known cell adhesion molecule, and propose that Fas2-mediated intermicrovillar homophilic adhesion complexes help stabilize the brush border
Employee perceived effect of leadership training: comparing public and private organizations
Get PDFThis study reports on the effectiveness of a year-long field experiment involving training in transformational and transactional leadership in the public and private sectors. Using before and after training assessments by employees of several hundred Danish leaders, the analysis shows that transformational leadership training is associated with increases in behaviors linked to both transformational leadership and the use of verbal rewards, but only for public sector organizations. There is no impact in private sector organizations. Transactional leadership training appears to be equally effective in stimulating the use of pecuniary rewards in both public and private organizations
