Amphibious Architecture: Living With A Rising Bay, Heather Christine Anderson

Master's Theses

Over the past century, sea level has risen nearly eight inches along the California coast and climate scientists suggest substantial increases in sea level as a significant impact of climate change over the coming century. This project explores the concept of creating a sustainable living environment for seaside residents in Redwood City as an alternative to permanent construction on land in the event of a substantial rise in sea level.

This project will generate a flood-resilient design solution that is capable of rising and falling with the water. In order to ensure the well-being of the inhabitants, I will analyze …

Analysis Of Environmentally Friendly Marking Ink For Military Equipment And Electronics, Liang Li

Master's Theses

Recent advancements in corrosion-resistance coating technology has reduce the use of environmentally harmful compounds such as Hexavalent Chromium by replacing Hexavalent Chromium in primers and topcoat. However, marking inks were neglected in the process. Products such as Enthone 50 series are still widely used, which contain compounds such as lead, hexavalent chromium, bisphenol A (BPA), Cadmium Sulfide, and more. Excluding catalyst compositions in Enthone, the chemicals in the ink alone contained three reproductive toxicant and numerous carcinogens. Therefore, it was essential to search and validate the performance of potential marking ink that would meet the standards in military applications.

Adapting The Job Demand/Control Model To A Team Level, Clark Calabrese

Master's Theses

A better understanding of sources of stress within a teamwork context might be gained by applying the Job Demands/Control Model of stress (Karasek and Theorell, 1990) to teams as the unit of analysis rather than only to individuals as it is conventionally done. Team performance is frequently treated as a shared team-level outcome; it seems reasonable to assume that shared team characteristics are likely to have effects on stress as well. In particular, teams are unique in their requirement for coordination between team members. Therefore, the present study proposes an adapted Team Job Demands/Control Model of team-level stress phenomena in …

Protist Facilitated Transport In An Artificial Soil Micromodel, Rebecca L. Rubinstein

Master's Theses

The soil microhabitat contains a complex network of microbial, biochemical, and physical interactions, all of which have very important implications for remediation technologies as well as agriculture. As a result, observing and quantifying this environment has been of recurring interest to scientists and engineers, but by nature many of these processes are difficult if not impossible to observe in situ. To that end, we have developed techniques utilizing soil-structured microfluidic devices for direct observation of soil microbial processes. Specifically, natural soil protists were observed moving through fabricated artificial soil networks, and their impact on the spatial and temporal distribution …

Aiding And Abetting: The Illegality Of Morocco's Nationalist Expansion Into Western Sahara And Their Support From The United States, Rachid H. Yousfi

Master's Theses

This paper will address the illegality of Morocco’s nationalist annexation of Western Sahara and how the United States plays the accommodating role through the selling of arms, economic aid, and diplomatic support. Considered as Africa’s last colony, the Saharawi people have not experienced the basic human right to self-determination and the right for independence. These rights are continued to be withheld for the sake of Moroccan nationalism and their “rightful and ethnic” claims to the territory, disregarding the International Court of Justice (ICJ)’s advisory opinion ruling in favor of Saharawi self-determination. It explores the chronology of the Saharawi population from …

The Economic Impact Of Wheelchairs For The Disabled In Ethiopia, Justin L. Grider

Master's Theses

Abstract: How do wheelchairs impact income and the possible channels of employment status and time allocation for the physically disabled? In order to improve opportunities for people with disability, it is imperative to know the effect that a wheelchair has on the lives of the disabled. Estimates from 261 participants across Addis Ababa, Ethiopia were taken to estimate a wheelchair’s impact across numerous time, economic and distance variables. I demonstrate how nearest neighbor covariate matching methods can be used to estimate how wheelchair beneficiaries would have fared had they not been given a wheelchair. Results show that current wheelchair users …

Heterogeneous Effects Of Commodity Price Shocks On Inflation Rates. Evidence From A Panel Study., Odbayar Batmunkh

Master's Theses

Do commodity price shocks have heterogeneous effect on countries based on their export and import profiles? I address this question through a panel study of 142 countries using Export and Import Indexes aimed at differentiating the retail pass-through and fiscal balance channel of transmission of Commodity Price shocks on inflation. The results show that an increase in the Export Index leads to a decrease in contemporary inflation while an increase in the Import Index leads to an increase in inflation in the next year. Average causal mediating effect of the Export Index on Inflation through the Fiscal Balance was shown …

Typhoons And Lower Birth Weight In The Philippines, Sarah Morrow

Master's Theses

Do typhoons impact birth weights of infants exposed to a typhoon while in utero? This research exploits the exogeneity and randomness of typhoons in the Philippines to estimate the impact of typhoon exposure as determined by wind speed on birth weights. Using four waves of the Demographic and Health Survey (DHS) data from the Philippines combined with temperature, precipitation, and rainfall data from the Philippines, I can empirically estimate the impact of a 1 m/s increase in wind speed on birth weights. I find that for certain subgroups of the population, specifically children born to mothers with primary education or …

Impact Of Mobile Money Usage On Microenterprise Evidence From Zambia, Laura I. Frederick

Master's Theses

Mobile money payment systems have spread rapidly around the world in the last decade. Given developing countries are powered by informal economies that traditionally have had limited access to information technologies, mobile payment system infrastructure has the potential to transform the way microenterprises conduct business. Through a pilot study in Livingstone, Zambia, I examine the effect of mobile money usage on microenterprise profits. I employ an instrumental variable strategy using the type of mobile operator as the instrument to address the selection bias in adoption, as mobile money services are available to everyone. In this urban context, I find initial …

How Is Sectoral Fdi Affecting Firms’ Performance In Mozambique?, Nilza A. Abdurramane

Master's Theses

I study the effect of sectoral FDI on firms’ performance in Mozambique from 2007 to 2010 through productivity and efficiency functions, using comprehensive firm level data. Although foreign ownership has a positive effect on firms’ productivity, my results show that in general, sectoral FDI has a negative and statistically significant effect on Mozambican firms’ productivity. The findings of this study are similar to previous studies that argued that positive foreign spillovers were not automatic. Using a stochastic frontier model, to measure efficiency, I find that in general foreign firms tend to be more efficient than domestic firms. However, using this …

Learning Together: A Case Study Of A Cooperative School’S Approach To Education, Ariana M. Ali

Master's Theses

This thesis is based on an in-depth case study of one cooperative pre-preschool and preschool in San Francisco. Qualitative research methods, such as observation and one-on-one interviews, were used to study the structure, culture, and community at the school. Cooperative schools have not been well researched or documented in academic literature and this study hoped to shed some light on this model of school organization. The parent-initiated and community-oriented nature of cooperative schools make them stand out as unique among the large, bureaucratically-run schools and daycares typically found in the United States. The results of this study highlighted four themes …

Directional Selective Neurons In Awake Lgn: Response Properties And Modulation By Brain State, Xiaojuan Hei

Master's Theses

Directionally selective (DS) neurons are found in the retina and lateral geniculate nucleus (LGN) of rabbits and rodents. In rabbits, LGN DS cells project to primary visual cortex. Here, we compare visual response properties of LGN DS neurons with those of layer 4 simple cells, most of which show strong direction/orientation selectivity. The response properties of these populations differed dramatically, suggesting that DS cells may not contribute significantly to the synthesis of simple receptive fields: (a) whereas the F1/F0 ratios of LGN DS cells are strongly nonlinear, those of simple cells are strongly linear, (b) whereas LGN DS cells have …

Matrilineal Asset Inheritance, Female Bargaining Power, And Household Welfare In Malawi, Nicholas T. Garcia

Master's Theses

Matrilineal inheritance practices in Malawi exogenously determine female land holdings at the time of marriage, allowing for the identification of the effect of increased female bargaining power on household consumption decisions. I use the matrilineal ethnicity of the head of household as an instrument for the share of total household land inherited by the female head or male head’s wife. I find that child’s height-for-age decreases with female assets, and evidence suggesting increased consumption from households’ own production. Since the food basket from own consumption is high in carbs but not nutritious, long-term child health suffers despite receiving more resources …

Can Community Water Projects Combat Child Diarrhea? Results From The Solomon Islands, Thomas G. Sackman

Master's Theses

There is a vast amount of existing literature that has empirically scrutinized whether or not community water projects have the ability to mitigate diarrheal disease. A strong and persistent belief thinks that community water projects do have the means, however, over the decades empirical work commonly finds this to simply not be true. This study expands the research question to the Solomon Islands. The research tests the hypothesis using a differences-in-differences identification strategy by utilizing the government’s staggered timing rollout of community water subprojects with whether or not a village received a community water subproject to test for a program …

The study uses a total of 36 variables on structural, environmental and neighborhood attributes from the 2010-2011 survey data on income, expenditures and living conditions for the Rwandan urban households. With the use of the semi-log form of the hedonic price model and the survey data, factors of urban properties are determined and quantitative estimates of the Willingness-to-pay for environmental amenities are determined. The analysis of …

Impact Of Typhoons On Children's Human Capital Investments In Filipino Households, Kate Zitelli

Master's Theses

Typhoons are a unique type of natural disaster affecting both developing and developed countries, causing both short and long-term destruction. Typhoons are random both in intensity and frequency, making them difficult to predict their strength and when they will strike. With global climate change, typhoons are expected to increase in both frequency and magnitude, making it important to understand their impacts. This study uses DHS data from the Philippines and a unique Filipino typhoon data set covering they years 1989-2008 to explore how typhoons affect household allocation of basic human capital investments, such as breastfeeding duration. Using OLS estimation and …

Effects Of Post-Race Nutritional Intervention On Delayed-Onset Muscle Soreness And Return To Activity In Ironman Triathletes, Jun Hashiwaki

Master's Theses

The purpose of this study is to examine the effect of a post-race nutritional intervention on DOMS and ability of triathletes to return to activity. Thirty-six triathletes participated in this study. Subjects were randomly assigned to either an intervention or control group by finish time. The intervention group received recovery shakes (540 kcal, 90g carbohydrate, 40g protein, 16g fat) both 1-hour and 3-hours post-race. DOMS was measured with a 100mm-visual analogue scale (VAS) and 11-point global rating of change (GRC) in standing position (static) and sitting-to-standing motion (active). DOMS was evaluated at 11 time points (pre-race, 1h, 3h, 12h post-race, …

Early Life Rainfall And Later Life Human Capital Outcomes In Bangladesh, Thomas Dreesen

Master's Theses

How does early life rainfall impact later life human capital outcomes in Bangladesh? This paper examines the effect of exogenous rainfall shocks that occur during individuals early-life on later life health, wealth and education outcomes of Bangladeshi women born between 1952-1988. I link historical rainfall for each woman’s birth year and Demographic and Health Survey (DHS) cluster of birth with current outcomes from the 1999/2000, 2004 and 2007 survey rounds of the DHS. This study finds that rural women with 20% higher than mean rainfall in their year and cluster of birth are on average 0.24 cm taller and score …

Attitudes And Beliefs Regarding The Collection Of Race, Ethnicity And Primary Language Information In Healthcare Settings, Roberto A. Henry

Master's Theses

Public health researchers, practitioners and policy makers are increasingly trying to uncover, quantify and address health disparities, which are differences in health outcomes among population subgroups (Nepaul et al., 2007). Health disparities are understood to be the consequences of differences in care, the health services infrastructure, and information systems available to persons by virtue of their gender, race, ethnicity, education level, etc. (U.S. Department of Health and Human Services, 2011; Institute of Medicine, 2009). In the United States, we commonly study health disparities occurring across racial and ethnic groups, requiring the collection of race, ethnicity and language data in order …

Wmost Case Study For Uconn’S Storrs Campus To Optimize Water Purchases From Connecticut Water Company, Joseph D. Albani

Master's Theses

The University of Connecticut currently provides potable water to its Storrs campus and Mansfield from groundwater pumps in the Willimantic and Fenton River Wellfields capable of producing 1.48 MGD and 0.8442 MGD, respectively. In 2005, sections of the Fenton River ran dry as a result of low flows and overuse. Since that time, the University has undertaken successful efforts to understand and manage its water resources. The wellfields’ supply is currently inadequate for the 15% margin of safety for peak monthly demands. Additionally, UConn is planning expansions bringing 6,500 more students to campus, with the facilities to accommodate them. UConn …

Women’S Empowerment And Community-Driven Development: Evidence From The Solomon Islands, Erin M. Steffen

Master's Theses

The study evaluates the impact to-date of a community-driven development (CDD) program on women’s empowerment in the Solomon Islands. Originally launched in 2008, the CDD program is known as the Rural Development Program (RDP). The RDP aims to foster employment and income growth by focusing on participatory development, demand-responsive provisions of government services, and the creation of a supportive economic environment for small-scale rural development. The RDP process mandates female involvement, which manifests predominately in the selection of community infrastructure projects and by participation in a RDP subcommittee known as the Sub-Implementation Committee (SIC). Members of the SIC are in …

Treating Wastes With Microbial Fuel Cells(Mfcs) And Microbial Electrolysis Cells(Mecs), Yan Li

Master's Theses

Two typical oxidized-status metals (Fe (III) and Cr (VI)) were studied as electron acceptors on cathodes in single chamber microbial fuel cells (SCMFCs) to explore novel sustainable technology for metal treatment in wastewater. The batch-mode tests indicated that the voltages of SCMFCs steadily increased with Fe(III) concentrations (10mg L-1, 30mg L-1, and 50mg L-1) and Cr (VI) concentrations (1mg L-1, 3mg L-1, and 10mg L-1). The maximum power density and current density reached at 658.34mW m-2 and 0.46mA cm-2 at 50mg L-1 of Fe(III), and reached at 419.31mW m-2 and 0.27mA cm-2 at 10 mg L-1 Cr (VI). The conversion …

Bimodal Approach Using Spectroscopy And Digitial Imaging To Assist Otitis Media Diagnosis, Kaitlyn M. Longo

Master's Theses

Otitis Media is defined as inflammation of the middle ear region associated with middle ear fluid. This condition typically follows an upper respiratory infection, is commonly misdiagnosed by physicians and can potentially lead to the inappropriate use of antimicrobial agents. ^[1] This thesis describes the design of a novel medical device that utilized spectroscopy and digital imaging to provide physicians with a unique representation of the middle ear. Published literature has been reviewed to assess the different approaches that researchers have studied to improve the diagnosis of otitis media, where, for example, research conducted by Thorton et al. and Boppart …
