Water, sanitation and hygiene for the prevention of diarrhoea

Background Ever since John Snow’s intervention on the Broad St pump, the effect of water quality, hygiene and sanitation in preventing diarrhoea deaths has always been debated. The evidence identified in previous reviews is of variable quality, and mostly relates to morbidity rather than mortality

The Evolution of International Sovereignty Norms and the Process of State-Level Norm Internalization

This thesis seeks to address both the evolution of international sovereignty norms and the process of state-level internalization of these norms by working across international relations theories. It poses the following, two-part, research question: have international legal sovereignty norms evolved, and if so, by what process have states internalized new sovereignty norms on the domestic level? It hypothesizes that traditional constructs of Westphalian sovereignty have evolved into a new sovereignty-modern norm, which is characterized by the emergence of positive rights in international law. It further hypothesizes that international norms frame domestic level cost-benefit analysis on the state level, which leads to domestic level internalization or rejection of these new norms in domestic law. It tests this theory through the use of a comparative case methodology, which encompasses two series of quantitative content analysis and a series of textual analysis of state-level cost-benefit decision-making. It concludes with a discussion of the implications of the findings of this study

Composite imaging techniques

A method for determining light source locations from specularity is discussed. The method was tested experimentally to show that the technique is viable for real world applications

Cost effectiveness analysis of prostate cancer treatments.

Medical care costs are escalating rapidly in the United States and confusion concerning optimal treatment protocol's contributes to the waste of medical resources. In this project an analysis of prostate cancer treatments was performed. This analysis was accomplished by examining each treatment alternative in terms of its complications, cost and effectiveness -- by cancer stage. In localized prostate cancer, radiotherapy and prostatectomy are more cost effective than other treatments. After prostate cancer has metastasized, hormone therapy is the most cost effective option
