Graduate Theses and Dissertations

During their life, humans are exposed to numerous substances that are naturally present in the environment or that are the result of man made processes, including heavy metals, persistent organic pollutants, pesticides and veterinary drugs. Some of these substances can leave residues in food products and possibly expose consumers to their potential toxic effects. To address these problems extensive regulatory efforts are devoted to prevent, detect and control these substances from reaching the food supply. However, given the vast diversity of food products that requires monitoring and the immense diversity of potential chemical contaminants, the need for an efficient and …

Campus Recreation Program Involvement, Athletic Identity, Transitional Loss And Life Satisfaction In Former High School Athletes, Katie E. Helms

Graduate Theses and Dissertations

Sports participation can result in strong associations with the athlete role for participants. While strong athletic identity can have positive implications, it can also create vulnerability to emotional difficulty following exit from sport (Brewer, 1993). Exit from sport is inevitable, resulting from a wide range of sources such as injury, aging, de-selection, or not qualifying to participate at a certain skill level. Despite a large proportion of high school students who play sports, there is little opportunity for continuation at the college level. This discrepancy often results in significant transitional loss resulting from exhausted athletic eligibility. The current study examines …

Changes In The Proliferation Of The Subventricular Zone Neural Stem Cell Pool Throughout Aging In The Murine Brain, Olayinka Edwards

Honors Scholar Theses

Previous studies regarding subventricular zone (SVZ) neural stem cells (NSCs) have either observed global changes in the SVZ niche containing NSCs or an impure NSC population. By imaging wholemount preparations of mouse brains and staining with molecular markers specific for proliferating NSC nuclei, the study was able to give a more accurate depiction of the SVZ NSC population than its predecessors. This study will quantify the percentage of proliferating NSCs at various ages of adult murine brain development in order to elucidate a possible correlation between NSC division kinetics and the declining neurogenic output witnessed with aging.

An Examination Of Chronic Pain Coping Strategies And Health Locus Of Control Among Prison Inmates, Joseph M. Mitrovich

All-Inclusive List of Electronic Theses and Dissertations

The present study evaluated the types of coping strategies for chronic pain implemented by 88 inmates, and the degree to which these inmates possessed an internal versus external locus of control. Based on the findings of previous research, it was expected that inmates would report utilizing passive coping strategies more often than active coping strategies, and that passive strategies would be associated with poorer adjustment to pain in terms of depression, pain intensity, and pain interference with daily activities. It was also expected that inmates would report higher levels of external locus of control beliefs than internal locus of control …

Razian Authority And Its Implications For Legal Ethics, W. Bradley Wendel

Cornell Law Faculty Publications

The question considered in the session was whether the concern of legal ethics is the morality of law, the morality of clients, or the morality of lawyers. The response I have been pursuing, in my book and elsewhere, is that all of these moral concerns are tied together in the lawyer’s role. The morality of law, clients, and lawyers are interrelated, but the political perspective is primary. The law serves a political purpose, of making public life possible despite first-order moral pluralism. When people disagree, either at the level of moral principles or over the facts that bear on the …

Fort Stanwix: Untenable, Or The Key To Defending The Mohawk Valley?, Joshua Ross Nare

Masters Theses

Due to the Select Supply System of 1780, New York was waiting on the coming grain harvest from the Mohawk and Schoharie Valleys, in order to provide its quota of provisions to Washington's army and the several forts in the state, including Fort Stanwix. Throughout the war, many officers and officials, held the common belief that the Mohawk Valley and its rich croplands could be defended as long as Fort Stanwix held. In May, August, and October of 1780, the Governor of Canada, Sir Frederick Haldimand, ordered raids on the Mohawk and Schoharie Valleys, which destroyed the harvests, preventing New …

The Role Of Peroxidase In The Defense Response Of Buffalograss To Chinch Bugs, Anh Hoang

Department of Entomology: Dissertations, Theses, and Student Research

In recent years, buffalograss, Buchloë dactyloides (Nuttall) Engelmann has gained popularity as a turfgrass because of its low maintenance requirement, drought tolerance, and limited pests and diseases. Within the last decade, however, the western chinch bug Blissus occiduus Barber has emerged as important pest of buffalograss. Considerable progress has been made toward identifying buffalograsses with resistance to the western chinch bug and understanding the mechanisms of the resistance. It has been hypothesized that chinch bug-resistant buffalograsses can effectively detoxify the elevated levels of Reactive Oxygen Species (ROS) through enhanced activity of ROS-scavenging enzymes, while ROS accumulates in the susceptible plants …

The Multilevel, Multicultural, And Multi-Temporal Ecosocial Framework Of Population Health : How Neighborhoods, Culture, And History Impact Health Outcomes And Produce Health Disparities, Lawrence Tarves Brown

Theses and Dissertations (ETD)

According to findings in the field of genetics, it has now been established that the impact of race on health is mostly a function of a people's lived experience, not their genetic make-up. Due to this, the role of race in the study of health outcomes and health disparities has traditionally been specified improperly in statistical models due to confounding with ethnicity. Additionally, the role of geography or the impact of neighborhoods on health is often not specified properly.

Thus, the author proposes a multilevel, multicultural, and multi-temporal ecosocial framework that explains the impact of neighborhoods on health and the …

Development And Evaluation Of Paclitaxel-Loaded Liposomal Formulations For Targeted Drug Delivery To Breast Cancer, Vinayagam Kannan

Theses and Dissertations (ETD)

The objective of this work was to develop and evaluate paclitaxel-loaded liposomal formulations for targeted drug delivery to breast cancer. The liposomal formulation was optimized to maximize drug loading and physical stability. Cholesterol and saturated lipid content showed a negative influence on paclitaxel loading. Short-term stability studies showed that optimum drug-lipid ratio is necessary for adequate physical stability. Biodistribution studies in mouse xenografts bearing MDA-MB-231 breast cancer using near infrared fluorescence imaging showed that the accumulation of tumor vasculature targeted long-circulating liposomes (LCL) in the tumor was significantly less than non-targeted LCL at 48 h. The accumulation of these liposomes …

Technology Capacity Development Through Oss Implementation: The Case Of Public Higher Education Institutions In Ethiopia, Nigussie Tadesse Mengesha

The African Journal of Information Systems

The Open Source Software (OSS) literature gives little attention to the study and practice of domain specific end-user OSS implementation in general and in the public sector of developing countries (DCs) in particular. This paper, however, investigates the trajectories of two OSS-based information systems (IS) implementation projects in a developing country (DC) context with the aim to uncover the practice-based learning and resource sharing evident among locally situated and globally dispersed developers and users. The result of the interpretative case study research shows that the OSS philosophy and practice of software development, implementation and ownership, facilitates for the emergence of …

Administrative Law, Martin M. Wilson, Jennifer A. Blackburn

Mercer Law Review

Even in tough economic times, the work of administrative agencies seems to continue with particularly robust growth at the state level. The number of contested agency cases seems to be rising, even those involving the most trivial details. Although the idea of more government is not fashionable in most corridors, higher levels of activity by existing governmental agencies will be the norm until the state's economic picture achieves measurable improvement.

This Article is a survey of cases from the Georgia Supreme Court and Georgia Court of Appeals from June 1, 2009 through May 31, 2010. The cases chosen for review …
