Young stars are surrounded by massive, rotating disks of dust and gas, which supply a reservoir of material that may be incorporated into planets or accreted onto the central star. In this dissertation, I use high angular resolution observations at a range of wavelengths to understand the structure, ubiquity, and evolutionary timescales of protoplanetary disks. First, I describe a study of Class I protostars, objects believed to be at an evolutionary stage between collapsing spherical clouds and fully-assembled young stars surrounded by protoplanetary disks. I use a Monte Carlo ra...

This dissertation proposes a computational technique for automated "invention" of conceptual schemes of thermal systems. The input provided to the automated problem solver is a description of the streams entering and leaving the system. The output is a network of elementary processes: compression, expansion, heating, cooling, and chemical processes. The problem solver seeks a network that is feasible, and offers an optimal (or at least favorable) combination of energy and capital costs. The synthesis process is modeled as a heuristic search conducted in a state-space of all possible design ver...

This thesis is an interdisciplinary study of the conflicts and tensions in the role of NHS complaints managers. The thesis sets out to explore the contradictions inherent in the role of complaints managers and the ways complaints managers deal with these contradictions. The interdisciplinary theoretical underpinning of the research is informed by conceptualizations of the complaints manager in the specific socio-legal sense of ‘complaints handler’/ third-party dispute handler;’ a broader public administration framework, of ‘administrator’/ bureaucrat, and finally a wide-ranging sociologica...

Software developer turnover can have disastrous effects on an organization due to the loss of business process knowledge, as well as acquired technical skills. Annual rates of turnover in information technology (IT) departments have been estimated at 20% or more with the cost of replacing technology workers ranging from 1.5 to 2.5 times annual salaries. This study purposely focused only on software developers as opposed to IT employees in general due to the critical nature of their work. The factors leading to turnover intention in this field are poorly understood; therefore, this study was d...

The primary objective of this study is to determine whether practicing personnelists and research scholars agree on what constitutes an effective performance appraisal system in public safety organization. If Personnel managers at public safety organization possess knowledge of the characteristics of effective performance appraisal system in public safety organizations, they are more likely to design and/or advocate performance appraisal system in public safety organizations that include these important attributes. In addition, the research is an opportunity for the academic community to learn...

Genetically modified foods present numerous ethical, environmental, health and legal challenges. This report synthesizes information from many websites, scientific journals, newspapers and books that discuss the controversy surrounding genetically modified foods. The author has attempted to show that although the future applications of agrobiotechnology appear promising, the ways in which it is currently being used and regulated should be evaluated with a healthy degree of skepticism.

This cross-cultural content analysis (which merged traditional content analysis method with semiotic concepts) compared advertising in the United States (a highly individualistic and low-context culture) and India (a highly collectivist and high-context culture). The study examined the characteristics, differences and similarities in advertising strategies and expressions. A stratified random sample of advertisements for consumer products was selected from nationally circulated news magazines and business magazines of each country between January 1993 and December 1994 (Time and Business W...

The Yasukuni Shrine -- Japan's national memorial enshrining the spirits of Japanesesoldiers killed in domestic and foreign wars -- occupies a peculiar chapter in Japanese history. Originally designed as a sanctuary to house the spirits of those who died in overthrowing the Tokugawa Regime, Yasukuni was nurtured by the state and then the military into a powerful religious and iconographic center to promote Japanese ultranationalism. Following the close of World War II, the Shrine became the subject of intense politico-religious debates as the Japanese, with the assistance of the internati...

Ever since Charles Darwin published The Origin of Species in 1859, genetic evolutionary theory has increasingly served as the foundation for fields that deal with organisms that arose by natural selection. This thesis argues that economic theory should integrate with Darwinian theory through the creation of a "genetic evolutionary economics". The promise of genetic evolutionary economics is a better understanding of human nature and, consequently, a more accurate and comprehensive economic science. Economic theory rests on a set of assumptions about human nature. These economic...

"Liberal order and software-agents" - long-established ideas and modern technology are bridged. The impulse for undertaking this effort comes from the observation that it becomes difficult for computer science alone to create order for and within machines. The growing complexity of computer systems, open networks like the Internet, and the increasingly social role of software entities push the traditional quest for total global control out of reach. Economic theory of social order offers extensive experience with such conditions, so that it can complement and guide research in computer science...
