Privatize Or Self-Operate: Decision-Making In Campus Services Management, Jeffrey Shelton Pittman

Theses and Dissertations in Urban Services - Urban Education

In the past colleges operated as communities in which teaching and almost every other aspect of campus life were managed by a campus entity. This is particularly true in the area of campus support services. In recent years, there has been a significant shift in the way campus services are provided. Increasingly, college and university administrators evaluate the benefits and potential problems of privatizing or outsourcing various service units. Currently, such services as bookstores, food preparation/service operations, and physical plant departments have been the primary services chosen for privatization.

This study examines the decision-making process governing the choice between privatization …

Experimental Investigation Of Elemental Incorporation In The Otoliths Of Larval And Juvenile Fish: Implications For Use As Environmental Recorders, Gretchen Bath Martin

Biological Sciences Theses & Dissertations

Innovative techniques for discerning fish stocks, identifying nursery habitats, locating spawning sites, tracing larval transport pathways, and quantifying the degree of population connectivity are required to meet the goals of sustainable management of marine capture fisheries. One of the most promising techniques is the use of elemental signatures in fish otoliths (ear stones), which record valuable life history data and serve as the link between fish and their environment. To validate the assumption that otolith elemental composition is a function of water elemental concentrations, and to address the possible effects of external variables such as temperature and salinity, the composition …

Boussinesq Model And The Relative Trough Froude Number (Rtfn) For Wave Breaking, Takashi Okamoto

Civil & Environmental Engineering Theses & Dissertations

The relative trough Froude number (RTFN) theory is a new phase-resolving type, wave breaking trigger model introduced by Utku (1999) and Utku and Basco (2002). Based on the moving hydraulic jump concept, this model provides a better implementation of wave breaking in terms of hydrodynamics. Development of computer resources permits the use of the phase-resolving type, Boussinesq wave models in nearshore areas. The Boussinesq equation, however, does not include the physics of wave breaking, so that an additional mechanism is required to initiate wave breaking in the model. The main objective of this study is to develop a new wave …
