A Cross-Sectional Age Comparison of the Self-System Between Younger and Older Adults

Description: One of the most perplexing problems in the psychology of aging is whether there are characteristic changes in aspects of personality over the life course. This study attempts to address issues relating to changes in the self-system believed to take place as individuals grow older. Of particular interest is what age differences exist in the four components of the objective self described by Atchley (1982): the ideal self, self-concept, self-esteem, and self-evaluation. In order to examine the di… more

The Eulerian Functions of Cyclic Groups, Dihedral Groups, and P-Groups

Description: In 1935, Philip Hall developed a formula for finding the number of ways of generating the group of symmetries of the icosahedron from a given number of its elements. In doing so, he defined a generalized Eulerian function. This thesis uses Hall's generalized Eulerian function to calculate generalized Eulerian functions for specific groups, namely: cyclic groups, dihedral groups, and p- groups.

The Stress Protein Response of Pimephales promelas to Copper

Description: Organisms synthesize stress proteins in response to a variety of stressors. The 68/70-kDa proteins (synonymous to the 72/73-kDa proteins) have shown to be the most promising stress proteins, and have been proposed as a biomarker of general organismal stress. The 68/70-kDa proteins were used in an antigen/antibody based approach to determine the duration of the stress protein response of Pimephales promelas following an acute exposure to copper sulphate.

Billy and Me and Other Stories

Description: The thesis begins with an introductory chapter that explains the problems that short story theorists encounter when they try to define the short story genre. Part of the problem results from the lack of a definition of the short story in the Aristotelian sense. A looser, less traditional definition of literary genres helps solve some of the problem. Six short stories follow the introduction. "Billy and Me," "Queen of Hearts," "The Whiskey Man," and "Psychedelic Trash Cans" are representative of… more

Rorschach Assessment of Object Relations Development in Sexually Abused Children

Description: Sexual abuse of children has profound negative effects on psychological development. This study examined the effects of sexual abuse on object relations functioning by using the Mutuality of Autonomy Scale (MAS, Urist, 1977) to score Rorschach protocols of 63 abused children and 60 non-abused clinical controls. The hypothesis that abused children would have less developed object relations than their non-abused counterparts was not supported. Neither was the hypothesis that children who experien… more

The Feminist Trollope: Hero(in)es in The Warden and Barchester Towers

Description: Although Anthony Trollope has traditionally been considered an anti-feminist author, studies within the past decade have shown that Trollope's later novels show support for female power and sympathy for Victorian women who were dissatisfied with their narrow roles in society. A feminist reading of two of his earliest novels, The Warden and Barchester Towers, shows that Trollope's feminism is not limited to his later works. In The Warden, Trollope acclaims female power and "woman's logic" throug… more
