Forest Regeneration On The Osa Peninsula, Costa Rica, Manette E. Sandor

Master's Theses

Woody species diversity of secondary forest has the potential to converge with that found in old growth forest. This study is the first to examine multiple aspects of species and reproductive trait diversity, and their relationship to each other, across a successional chronosequence. Species richness and species diversity increases with increasing age of forest. Diaspore size and diversity as well as fruit size generally increased with increasing age of forest, but fruit size diversity did not. Abundance of animal-dispersed species increased whereas wind-dispersed species decreased in abundance over succession. Insect-pollinated individuals were most abundant overall. Diaspore diversity, pollination diversity, and …

Condition-Dependent Risk Assessment Of Large-Scale Grid-Tied Photovoltaic Power Systems, Sherwin Li

Master's Theses

This thesis reviews the methods for evaluating the reliability of large PV systems and techniques for quantifying the impacts of PV interconnection on distribution system reliability. In addition, a comparative study is performed to evaluate the seasonal condition-dependent risk performance of central-inverter and string-inverter grid-tied PV power systems. Major contributions include: 1) risk analysis of seasonal impacts for string and centralized PV systems. Seasonal sensitivities of PV system risks to system structures, temperature variation, solar insolation, and capacitor equivalent series resistance are analyzed; and 2) the incorporation of the effect of operational conditions and the aging failure model into the …

Game Theory Approach To Transportation Network Vulnerability Measurement, Qixing Wang

Master's Theses

The vulnerability of a transportation network is strongly correlated with the ability of the network to withstand shocks and disruptions. A robust network with strategic redundancy allows for the redistribution or reassignment of traffic without unduly compromising system performance. As such, high-volume edges with limited alternative paths represent system vulnerabilities – a feature of transportation networks that has been exploited in the past to identify critical components. In this thesis, a mixed-strategy, two opponents, non-zero sum, combinatorial game theoretical framework are presented for measuring network vulnerability. Two solution approaches (Shortest Path Algorithm with Entropy function (SPE) & User Equilibrium Assignment …

Detection Of Genomic Inversion From Single End Read, Pankaj Ghimire

Master's Theses

Structural Variations (SVs) are genomic rearrangements that include both copy-number variants,such as insertion,deletions, duplications and balanced variants like inversion and translocations. These SVs are getting more attentions for research and investigation because of their role on human phenotype, genetic diseases and genomic rearrangements. Evolution of Next-generation Sequencing has provided golden opportunities to investigate these variants and make their wider and clear spectrum in human genome. This investigation includes identification of type of SVs and their breakpoints at base pair level. For their effective identification and breakpoint resolution, many techniques are devised mainly based on paired end read. With relatively low …

A Finite Difference Implementation Of Phase Field Theory, Nicholas W. Oren

Master's Theses

Computationally handling cracks generally results in numerically unstable results. Specifically handling the infinite stresses at the crack tip as well as the abrupt change from virgin material to failed material creates numerical instabilities. This project seeks to determine if phase field physics theory, particularly the physics based modification developed by B. N. Cassenti, can be appropriately applied to cracks. Phase field theory introduces an additional state variable, the phase of the material. The phase represents the level of failure (by cracking), and diffuses the failure along a crack by specified equations. The modification, based on a variational principle, was tested …

Investigation Of In-Situ Immobilization Of Contaminated Sediments Using Alginate Gels For The Reduction Of Ecological Risk, Michael V. Podany Mr.

Master's Theses

Remediation methods for contaminated sediments include dredging, treatment and disposal and sediment isolation through capping. These methods are costly and adversely impact local ecosystems, in some cases causing major disturbances to the sediment bed and water column. A new remediation technique is proposed for slowly biodegradable contaminants using alginate hydrogels as a binding agent of sediment. The rational is that sediment particles bound in alginate hydrogel are less likely to be resuspended and the treatment is less disruptive than capping. Here we show addition of alginate increased the shear strength of sediment comprised of defined particle sizes. The increase in …

Weather-Based Damage Prediction Models For Electric Distribution Networks, David W. Wanik

Master's Theses

From thunderstorms to hurricanes, electric distribution networks are subject to a wide range of warm weather storm events. Tropical Storm Irene (2011) and Hurricane Sandy (2012) are two events in recent memory that disrupted over half of The Connecticut Light and Power Company’s (CL&P) service territory, which left some customers without power for up to eleven days. This research study investigates a damage prediction framework for both thunderstorms and hurricanes that combines two generalized linear models to probabilistically determine the occurrence and extent of damages, known as trouble spots, to the overhead power distribution network. The models are inputted with …

A Depolymerization Based Model Of Neuron Growth Cone Shape And Motility, Neerajha Nagarajan

Master's Theses

Cell migration is a ubiquitous process underlying critical biological mechanisms like wound healing, cancer metastasis and even neuron growth cone motility. It is a critical process for the living organisms as it ensures proper functioning of the system, for example, crawling fibroblasts endure closure of wounds during wound healing. Here we focus our interest on neuron growth cones, a sensory and motile organelle present at the tip of extending neurites, like the axons, in neurons. These are responsible for neuron pathfinding onto specific targets and synapses, in responses to various guidance cues. Interestingly, the motility of the growth cones is …

Effects Of Neonatal Hypoxic Ischemic Brain Injury On Spatial Working Memory, Amanda L. Smith

Master's Theses

Children born prematurely or at very low birth weight (VLBW) have an increased risk for hypoxic ischemic brain injury (HI). HI refers to a lack of adequate blood and oxygen flow in the brain. HI can also occur in the term infant due to birth complications such as prolonged labor, placental dysfunction, or cord prolapse. In both populations (though exact patterns of neuropathology vary) brain damage is likely to occur in the form of decreased hippocampal and cortical volume, and enlargement of the ventricles (Kesler et al., 2004, Nagy et al., 2009). Resulting neuropathology can in turn lead to cognitive …

Analysis Of The Enzymatic Decomposition Of Barley Starch To Simple Carbohydrates, Mark Mathiew Williams

Master's Theses

The decomposition of barley starch plays a fundamental role in the final quality of fermented beverages in the brewing industry. The process of mashing involves steeping milled barley in water to stimulate the enzymatic decomposition of starch into simple carbohydrates. The temperature of the water significantly impacts the activity of the enzymes and in turn the resulting concentrations of sugar products. A kinetic model accurately predicting the types and quantities of sugars formed as a function of mash temperature would serve as a tool to tailor sugar profiles and optimize mashing procedures for a desired product.

Sixty minutes mashes were …

Role Of Tonic Protein Kinase A On Sk2 Channel Expression, Krithika Abiraman

Master's Theses

Small conductance calcium-activated potassium channels (SK) play a fundamental role in synaptic transmission, plasticity, learning and memory (Hammond, 2006; Faber, 2008; Lin et al., 2008) . A very recent study successfully combined single molecule atomic force microscopy (AFM) and toxin pharmacology to quantitatively map SK channels in living neurons (Maciaszek et al., 2012). In addition to localizing native SK channels, this study also showed that SK channel distribution is dynamic with a decrease in SK channel surface expression upon addition of forskolin (FSK), a protein kinase A (PKA) activator. This finding raised further questions about the mechanism through which FSK …

Women's Mobilization In Latin America: A Case Study Of Venezuela, Brianna Russell

Master's Theses

Abstract

I examine the following elements in regards to women’s mobilization in Latin America and Venezuela from the late 1950s to the present: (a) the influence of the state and economy on times when women mobilized (b) class division within the movement (c) women’s demands during different time periods (d) the ways in which women were successful in working towards gender equality. This thesis reviews the literature on women’s mobilization in Latin America during the second half of the twentieth century. I find that women mobilized across class lines with the masses to end dictatorships. Women demobilized during transitions to …

Between Facebook And Boas: Kichwa Indigenous Identity In Alto Napo And Challenges To Multiculturalism In Ecuador, Anna Maria Fernandez-Marti

Master's Theses

This qualitative study examines contemporary Kichwa indigenous identity formation in the Alto Napo region of Ecuador through Bourdieu’s concept of symbolic capital. Following an extended-case method, I analyze the articulation of indigenousness (as an idealized expression of tradition) vis-à-vis the power relationships of the actors involved in such process. A combination between participant observation, daily field notes and twelve tape-recorded interviews during a two-month research allowed me to deconstruct essentialist portrayals and stereotypes of Kichwa indigenous peoples in Alto Napo, and confirm that their identity is hybrid, multiple and shifting. A comparative analysis between urban and rural social dynamics in …

I employed content analysis to analyze the major features of 427 news reports about the economic interaction between the two countries. The research focused on the key media frames in the two sets of news media, the factors that shaped these media frames, and the real meanings behind those reports. The study found both similarities and differences. The two sets of media showed significant differences in their reporting of news and events about economic issues in terms of the selection of topics, and the discourse …

A Practical Scale For Multi-Faceted Organizational Health Climate Assessment, Zandra M. Zweber

Master's Theses

The current study sought to develop a practical scale to measure workplace health climate in a way that has not previously been conceptualized – as a three-faceted approach from the employee perspective serving as an indicator of a healthy organization. The goal was to create a short, useable yet comprehensive scale that could translate into practical use by organizations and occupational health professionals planning workplace interventions. To accomplish this, the proposed multi-faceted organizational health climate scale (MOHCA) assesses three-facets which match up with three organizational levels: 1) organization 2) supervisor and 3) workgroup. Ten items were developed and tested on …

Cultural Traditions And The Reproductive Health Of Somali Refugees And Immigrants, Nancy S. Deyo

Master's Theses

Millions of Somalis began fleeing their country in 1991 to escape the civil war. The largest Diaspora of Somali refugees in the United States currently reside in Minnesota. Utilizing a qualitative research approach, four focus groups with 25 Somali women, two focus groups with 12 Somali men, one focus group with Somali religious leaders and seven in-depth interviews with American healthcare professionals were conducted in Minneapolis to help develop culturally sensitive reproductive health programs for Somali mothers. Twenty key distinctions between Somali cultural traditions and Western medicine were identified. For many Somali women, prenatal care is a new concept. There …

Constrains On Freedom Of Expression In Turkey: The Effects Of Article 301, Armine Sargsyan

Master's Theses

Concerns over human rights violations in Turkey by the European Union (EU) have hindered the Republic of Turkey’s accession to the EU. Freedom of expression has been denied through a number of laws since the creation of the Republic in 1923. This thesis presents how and why speech has been constrained in Turkey, and it provides an argument that Ottoman history has a direct impact on the country’s politics today. It also examines the implications of legislation that has been applied to silence individuals addressing controversial issues in public. In particular, Article 301 of the Turkish Penal Code has been …

Why Eu Work-Family Reconciliation Policies Fail In Italy: A Feminist Legal Analysis, Chrystal Orozco

Master's Theses

Following the establishment of the European Parental Leave Directive (96/34/EC), the female employment rate in Italy is still ranked the third lowest in the European Union (EU) and Italian women continue to do twice as much household work as Italian men. Parents, especially women, struggle to find a balance between professional work and their family lives in a society that encourages the traditional gendered roles of the housewife and the breadwinner. The following study is a theoretical analysis of the Parental Leave Directive and the potential domestic influences that may prevent Italy from progressing socially towards gender equality. This study …

Countering Youth Incarceration: Community Strategies In New Orleans And Cape Town, Ariel Marshall

Master's Theses

This research project looks at community-level remedial strategies addressing high youth incarceration and recidivism rates in the cities of Cape Town and New Orleans. Working within a theoretical framework of structural violence, I argue that the dominant discourse of Criminal Justice is based in punitive and retributive methodologies that have severe and long term implications for the psychological and social well being of detained youth, as well as the communities to which they return after imprisonment. My aim was to take a ‘bottom-up’ approach and examine the community-based projects in the two cities, which are developing counter-hegemonic knowledge and practices …

Iran In U.S. Corporate And Regional Media: A Content Analysis Of The New York Times, The Washington Post, Rooz Online, Al Jazeera And Iran Review, Justin Hyde

Master's Theses

There has been an increase in tension between the United States government and the Islamic Republic of Iran over the past decade. A number of events including the US- led invasions of Iraq and Afghanistan and the expansion of Iran’s nuclear program have strained this fragile relationship. The U.S. and its allies contend that Iran’s nuclear program is intended for arms proliferation while the Islamic Republic of Iran states it is for domestic power and research. Much of this conflict has played out in news media, which have a vital role to provide information, analysis and opportunities for dialogue as …

Oil, Power, And Discourse: How Chevron Evaded Its Dues To The Indigenous Communities Of The Ecuadorian Amazon, Kine Norland

Master's Theses

Abstract

The principal objectives of this thesis were to shed lights on the backside of oil and to question the great power of big corporations. I researched why Chevron refused to acknowledge its legal obligation to remedy the complex problems it has caused in the Ecuadorian Rainforest. The catastrophes the indigenous communities have been facing are about to change as a result of grass root mobilization against Chevron. By the use of observations, discourse analysis of the media, and the use of theories from Michel Foucault, I was able to explain how Chevron has managed to escape from the terrible …

The Lavender Tide: Lgbtq Activism In Neoliberal Argentina, Andrew Shaffer

Master's Theses

Beginning with the legalization of same-sex marriage in 2010 and following up with the passage of the gender identity law of 2012, Argentina has quickly catapulted itself to the forefront of LGBTQ (lesbian, gay, bisexual, trans*, queer) rights in the world. This study sets out to answer a simple question: how did these vast legal changes come about in a country whose LGBTQ citizens are still met with hostility and discrimination? In order to answer this question I look at the ways LGBTQ activists have argued for the civil rights that they have achieved, and measure their success by analyzing …

A Tale Of Two Superpowers: Nigeria And China Relations, Faouziatou Aboudou Kabassi

Master's Theses

The study discusses the historical development of the Sino-Nigerian bilateral relations. The paper provides a detailed view of china's FDI in Nigeria and the diverse challenges faced by the oil rich country to develop its own economy through NEEDS as a result of china's economic power. China’s partnership with Nigeria is ideally for economic growth but practically poisonous to Nigeria’s development goals as China is solely pursuing its own interest and diverting its partner from working toward its NEEDS goal. A deep investigation of the relations should be reviewed for both countries. This will be needed to produce vital economic …

The Odious Debt System, Andrew Hanauer

Master's Theses

Over the past forty years, African countries have accumulated enormous quantities of external debt. Today, this debt is heavily burdensome; money spent on debt service is money that cannot be invested into infrastructure development, health, education, or other areas that might benefit the large number of Africans who live in poverty. Calls for debt forgiveness have led western institutions to forgive a portion of this debt, but have not addressed the question of whether or not this debt is legitimate in the first place.

Similarly, academic proposals for the classification and subsequent repudiation or forgiveness of so-called "odious debt" have …
