Structural Holes and Simmelian Ties: Exploring Social Capital, Task Interdependence, and Individual Effectiveness

In contrast, Coleman (1990) and Simmel (1950) have suggested that network closure, exemplified by large numbers of Simmelian ties, enables actors to develop trust, cohesiveness, and norms which contribute to effe… more

Symmetrical Features of Nikolai Medtner's Language: The Grzovaya Sonata, Opus 53 No. 2

One of Medtner's thumbprints, symmetrical contrary voice-le… more

Techniques of Sensual Perception: The Creation of Emotional Pathways

Thus, understanding how to design an art form to contain strong sensual attributes may increase the possibility of an aesthetic experience. Since aesthetics is an experience of sensations perceived when in contact with a creative form in any artistic discipline, it is necessary for an artist to understand the na… more

Animals-as-Trope in the Selected Fiction of Zora Neale Hurston, Alice Walker, and Toni Morrison

Description: In this dissertation, I show how 20th century African-American women writers such as Zora Neale Hurston, Alice Walker, and Toni Morrison utilize animals-as-trope in order to illustrate the writers' humanity and literary vision. In the texts that I have selected, I have found that animals-as-trope functions in two important ways: the first function of animal as trope is a pragmatic one, which serves to express the humanity of African Americans; and the second function of animal tropes in African… more
