The Marshall Islands, a small island developing nation, has a significant solid waste problem. The atoll environment of the Majuro, the capital of the Marshall Islands, is one of scarce land and overpopulation. Increasing Western influences has been a major factor in this solid waste problem. This problem has created health issues and is an impediment to the development of a tourism industry, which is essential to the development of economic opportunities. Responsibility for solid waste management in Majuro is divided between several governmental and non-governmental agencies. This system is dysfunctional as there is little or no cooperation between the agencies. Although many consultants have developed recommendations, no action has been taken. Developing an action plan to consolidate solid waste management under one authority is important to solving of this solid waste problem. This project proposes legislation creating a solid waste management authority that will have the power to regulate all aspects of solid waste and help implement education and awareness to the people of the Marshall Islands.

The waste of plastic beverage bottles creates environmental problems and takes up a large volume of landfill space. The high rate of consumption of plastics in the State of Florida is challenging the disposal capacity of waste authorities. The lack of the reverse vending machines in the State of Florida, including applicable scientific or technical literature represented an opportunity for this research to discuss the applicability of this equipment as a potential solution for the management of the plastic waste in Florida. With this research document, I will propose a recycling system for plastic bottles made with PET based on the implementation of reverse vending machines, stressing the importance of the creation of policies that promote recycling and public participation.

Water quantity and quality issues worldwide are causing nations to consider alternate sources for drinking water. Desalination and other membrane processes for treatment of seawater and brackish inland waters have been in use for the past quarter century and are growing in use worldwide. These treatment processes create a highly concentrated waste stream in which the principal constituents are dissolved solids. This report provides an overview of desalination methods and the methods available to dispose of this waste stream. Innovative technologies being studied for possible future use are also discussed.

The purpose of this investigation was to determine if the way patients are informed of the diagnosis of multiple sclerosis (MS) affects their feelings about themselves as people with MS. Building on illness narrative, I hoped to examine how patients “storied” their experience of being informed of the diagnosis of MS and whether this “storying” had a lasting impact on their self-concept. The alternative would be that no connection exists between how a neurologist informs a patient of the diagnosis and how a person makes sense of their diagnosis and life with MS. Due to study limitations (e.g., small sample size, threat of response bias), the results are unclear about whether the way in which the news is broken has a lasting effect on patients' perceptions. However, review of the literature and patient responses indicate that there is a need for psychological intervention when patients are diagnosed with MS.

Coastal erosion is an important and constant issue facing coastal areas all over the world today. The rate of coastal development over the years has increased, in turn requiring that action be taken to protect structures from the threat of erosion. A review of the causes of coastal erosion and the methods implemented to control it was conducted in order to determine the best course of action in response to coastal erosion issues. The potential positive and negative economic and environmental impacts are key concerns in determining whether or not to restore an eroding beach and which erosion control method(s) to implement. Results focus on providing a comparison of these concerns as well as recommendations for addressing coastal erosion issues.

Subsistence in Alaska is currently being impacted by naturally occurring factors such as global warming, species migration shifts, and the declination of fishery and wildlife populations. Not only are external factors pressuring the debate, management strategies from the dual management operation appear to have failed. The current national focus has been centered on federal policy changes regarding subsistence. This project extends the federal subsistence review process into the state management of subsistence and provides practical solutions for enhancing both policy programs.
