An investigation of the relationships between job characteristics, satisfaction, and team commitment as influenced by organization-based self-esteem within a team-based environment

Description: Team-based management is a popular contemporary method of redesigning jobs in order to more effectively utilize the human potential of employees. The use of such management techniques should result in increased satisfaction and team commitment; however, many research studies have failed to demonstrate increases in affective outcomes on the part of the employee. The research question examined in this study is, "What specific job dimensions and situational factors result in higher levels of satis… more

An analysis of the Sonata for Trumpet and Piano by Peter Maxwell Davies, identifying the use of historical forms, and the implications for performance.

Description: The Sonata for Trumpet and Piano by Peter Maxwell Davies is one of his earliest works, and a notoriously difficult work to perform. While using serialism and other twentieth-century compositional techniques, this work also uses older historical forms, including sonata-allegro and sonata-rondo forms. An analysis of the work is presented, identifying the older historical forms, and considerations for performers when making decisions on how to perform the work are provided.

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

Description: Organizational development and change (ODC) is a broad field because change occurs in all organizations, occurs at multiple organizational levels, consists of numerous interventions, and can impact multiple outcomes. Many ODC efforts attempt to examine the effectiveness of their initiatives, yet fail to account for the quality, or rigor of their methods. The purpose of this paper is to examine how methodological rigor and intervention implementation quality impact ODC outcomes. The results ind… more

Generic Algebras and Kazhdan-Lusztig Theory for Monomial Groups

Description: The Iwahori-Hecke algebras of Coxeter groups play a central role in the study of representations of semisimple Lie-type groups. An important tool is the combinatorial approach to representations of Iwahori-Hecke algebras introduced by Kazhdan and Lusztig in 1979. In this dissertation, I discuss a generalization of the Iwahori-Hecke algebra of the symmetric group that is instead based on the complex reflection group G(r,1,n). Using the analogues of Kazhdan and Lusztig's R-polynomials, I show th… more

Stretched Out on Her Grave: Pathological Attitudes Toward Death in British Fiction 1788-1909

Description: Nineteenth-century British fiction is often dismissed as necrophillic or obsessed with death. While the label of necrophilia is an apt description of the fetishistic representations of dead women prevalent at the end of the century, it is too narrow to fit literature produced earlier in the century. This is not to say that abnormal attitudes toward death are only a feature of the late nineteenth century. In fact, pathological attitudes toward death abound in the literature, but the relationship… more

Stretched Out On Her Grave: The Evolution of a Perversion

Description: The word "necrophilia" brings a particular definition readily to mind – that of an act of sexual intercourse with a corpse, probably a female corpse at that. But the definition of the word did not always have this connotation; quite literally the word means "love of the dead," or "a morbid attraction to death." An examination of nineteenth-century literature reveals a gradual change in relationships between the living and the dead, culminating in the sexualized representation of corpses at the … more

Evaluation of virulence in wild type and pyrimidine auxotrophs of Pseudomonas aeruginosa using the eukaryotic model system Caenorhabditis elegans.

Description: The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial… more

The Apologist Tradition: A Transitional Period in Southern Proslavery Thought, 1831-1845

Description: Early antebellum defenders of slavery acknowledged that slavery created problems for southern society. They contended, however, that slave society was better and more natural than other forms of social organization. Thomas R. Dew, William Harper, and James Henry Hammond each expressed a social philosophy in which slavery had a crucial role in preserving social order. They argued from the basis of social organicism, the idea that society should have an elite that controlled the masses. For all t… more
