Development Of A Human Lung Cancer Cytochrome C-Gfp Reporter Cell Line To Study Anti-Cancer Drug Responses In Apoptosis Pathways, Sidra A Piracha

Dissertations and Theses

"Currently chemotherapy and radiotherapy are the most popular methods for cancer treatments after surgery, but lack of specificity and are thus toxic to the healthy human cells. Studies have shown that targeted therapies have been linked to activation of apoptosis signal pathways (cascade of caspases) in cancer cells including intrinsic and extrinsic pathways. One of the major pathways leading to caspase activation involves the release of cytochrome-c from mitochondria. However, in some tumor cells this pathway is inactivated due to the mutation of mitochondria membrane stabilizing proteins (e.g. Bcl-2, Bcl-xL). Therefore, the overall objective of this proposal was to understand …

Effects Of Mild Heating On The Osteogenic Differentiation Of Human Mesenchymal Stem Cells During Inflammation, Kristifor Sunderic

Dissertations and Theses

"Current surgical procedures to treat osteoarthritis have varying degrees of success, but carry inherent risks and a finite life expectancy. A more permanent solution is a treatment that regenerates biologically viable tissue that integrates with the patient and retains functionality. For maximal effectiveness, such a treatment should also repair bone loss known to occur in osteoarthritis and attenuate chronic inflammation that can obstruct healing. Mesenchymal stem cells have great potential to be used as part of a novel therapy for bone and cartilage regeneration. They are a highly regulated, self-renewing population of cells with potent mechanisms to avoid allogeneic rejection, …

Removal Of Antibiotics From Contaminated Waters Using Natural Zeolite, Booyoung Lee

Dissertations and Theses

The occurrence of residual antibiotics in the environment has been a worldwide issue, and there is a need to develop methods for antibiotics removal from contaminated water. In this thesis work, the sorption of four antibiotics, namely chlortetracycline (CTC), oxytetracycline (OTC), ofloxacin (OFL), and enrofloxacin (ENR), on natural zeolite was investigated. The impact of pH and natural organic matter (NOM) on the sorption process was examined, and the maximum sorption capacity was calculated using the Langmuir-Freundlich sorption model. The results showed that at a neutral pH the maximum sorption capacity for the antibiotics was up to 8 mg/g. The sorption …

Why Oil Production Has A Negative Impact On Socioeconomic Development In Chad?, Annicette Kessely

Dissertations and Theses

"Oil production in Chad is considered one of the most important Sub-Saharan investments in Africa. In 2000, the World Bank agreed to finance oil production under the condition that oil revenues would be invested in socioeconomic development projects. Furthermore, the World Bank emphasized that oil revenues should be used in a transparent and accountable matter.1 Oil production started in Chad in 2003 and brought billions of dollars to the government. Nevertheless, the Chadian population continues to live in extreme poverty. The purpose of this paper is to evaluate the impact of oil production on socioeconomic development. It will demonstrate that …

Object Detection And Recognition For Visually Impaired People, Shuihua Wang

Dissertations and Theses

"Object detection plays a very important role in many applications such as image retrieval, surveillance, robot navigation, wayfinding, etc. In this thesis, we propose different approaches to detect indoor signage, stairs and pedestrians. In the first chapter we introduce some related work in this field. In the second chapter, we introduced a new method to detect the indoor signage to help blind people find their destination in unfamiliar environments. Our method first extracts the attended areas by using a saliency map. Then the signage is detected in the attended areas by using bipartite graph matching. The proposed method can handle …

The Post-Conflict Reconciliation Process; Truth Commissions, Tomoe Nakagawa

Dissertations and Theses

"Since the end of the Cold War, our world has seen an increase in intra-state conflict and the emergence of the notion of state accountability for the treatment of their citizens. Furthermore, sovereign states increasingly see that it is in their interest to apply the rule of law and human rights norms beyond their borders. While peace building efforts have been achieved through criminal prosecutions, truth commissions, reparation programs, and vetting, a truth commission, in particular, has been progressively used in the past decade as one aspect of transitional justice measures. This increase in use illustrates its popularity in handling …

Minority Rights In Europe; The Roma Population As A Case Study, Michael Brooks

Dissertations and Theses

"This thesis undertakes an in-depth analysis of the minority rights of Roma populations living within the European Union. The Roma people face economic, social and political discrimination that permeates both government institutions and society in general and has prevented this minority group from integrating into the workings of society. This issue is important because the Roma lack a positive identity both of themselves and from other groups, which deprives the state of an important source of productivity. This is due in part from their own actions based on chosen isolation to some degree, and also because some Roma have become …

Does Democratic Peace Theory Apply To Small Powers? A Case Study Of Turkey And Israel, Robert Lattin

Dissertations and Theses

This thesis hypothesizes that shared democratic values and institutional constraints, proposed as explanations by Democratic Peace Theory (DPT), should in theory prevent small powers from engaging in physical conflict. However, because these democracies are small and developing, these constraints may not influence outcomes in the same way as they do in larger and more developed powers. To test this hypothesis, a dyadic case study was conducted of the relationship between Turkey and Israel. Specific focus was given to two related events, both of which could have resulted in a physical conflict between the two countries: the May 2010 Flotilla incident …

Iran; A Nuclear Super Power? Understanding Nuclear Ambitions, Lindsey Sera

Dissertations and Theses

"Iran is a nation in flux, with a history of political strife and revolution. The everchanging political atmosphere in the nation has made Iran an unpredictable political actor. It is a nation coping with a new governing system, just a few decades out from a revolution from the reign of the Shah of Iran. The fall of reformism has left the nation politically isolated from the international community. Iran is a nation on the brink of nuclear weapon capabilities and with strained relations there is little comfort in sight for an amicable solution. The conservatives of today's Iran seek independence …

The Security & Development Nexus, Manizha Sayar

Dissertations and Theses

In the 21st century the need for conflict and post-conflict reconstruction efforts have increased since a number of conflicts in Asia, Africa and Eastern Europe necessitated the building of newly-democratized states while aiming to achieve security and promoting development. The difficulties that arise when helping to reconstruct states that have failed or those approaching a “failed state” status is that they are neither stable nor have a secure environment which prevent the opportunity for economic development, despite reconstruction efforts. These are the most difficult of situations due to the interconnectedness and direct correlation of the two significant criterions for established …

Exploration Of The Endothermic And Exothermic Reactions Of Calcium Oxide And Magnesium Oxide And Design Of A Vessel For A Thermochemical Heat Storage System, Jorge Pulido

Dissertations and Theses

A high temperature Thermal Energy Storage (TES) system has been investigated for use in solar thermal power plants or in vehicles to preheat the engine and/or the cabin in cold weather. The idea is to store surplus thermal energy and then release it on demand to heat a working fluid. The stored heat can be used to generate electricity after sunset or to meet the peak loads. These would lead to an improvement in energy efficiency, reductions in energy imports from foreign sources and total energy-related emissions. The basic operating principle involved in the TES system is a thermochemical reaction …

The Impact Of Internet On Economic Growth In Bangladesh, Mohammed Meah

Dissertations and Theses

"The purpose of this paper is two fold. The first goal is to reveal that an increase in the number of Internet users has a positive effect on economic growth within a nation. Based on this causality, the next objective is to demonstrate that less developed countries, specifically Bangladesh is in the best position to increase investment in the Internet to experience economic growth. Finally, the implications of Internet penetration on various economic sectors in Bangladesh are discussed. Panel data for 244 countries from the World Bank from 1990-2011 is used to carry out the experiment for the first goal. …

Poor And Marginalized Women Active In The Public Arena During Nepal's Peace-Building Process After Maoist Insurgency, Rakshya Pandey Shrestha

Dissertations and Theses

In Nepal, a country where more than half of the population is female, the society is blatantly patriarchal, and the social system is based on caste, class, ethnicity and gender discrimination. It cannot be denied that the violent Maoist insurgency led to socioeconomic and political deterioration in the country. The decade- long violent conflict killed an estimated figure of more than 13,000 people and has displaced even more. Currently, the country is in the process of transformation and peace-building and is moving towards adjusting the past discrepancies to address root causes of the insurgency. However, the Maoist insurgency also brought …

Diffuse Optical Imaging Using Decomposition Methods, Binlin Wu, M. Alrubaiee, W. Cai, M. Xu, S. K. Gayen

Publications and Research

Diffuse optical imaging (DOI) for detecting and locating targets in a highly scattering turbid medium is treated as a blind source separation (BSS) problem. Three matrix decomposition methods, independent component analysis (ICA), principal component analysis (PCA), and nonnegative matrix factorization (NMF) were used to study the DOI problem. The efficacy of resulting approaches was evaluated and compared using simulated and experimental data. Samples used in the experiments included Intralipid-10% or Intralipid-20% suspension in water as the medium with absorptive or scattering targets embedded.

Oh Canada, Your Home On Native Land: Settlement, Development, And Conflict In Southern Ontario, Shana Siegel

Dissertations, Theses, and Capstone Projects

On February 28, 2006, members of the Haudenosaunee Six Nations reserve in southern Ontario physically occupied and halted construction on a housing development bordering their reserve. The Haudenosaunee claimed that the site was part of a larger tract of land that they had never surrendered, and they vowed to remain on the land as long as necessary prevent the planned development from taking place. When police had still not removed the Haudenosaunee protesters almost two months later, some 2,000-3,000 local non-Native residents began voicing their frustration and anger in regular anti-protest rallies. On some occasions, these rallies escalated to the …

Facebook: Shifting Privacy, Identity, And Power Online, Rachel Verni

Dissertations, Theses, and Capstone Projects

Due to staggering technological shifts in recent decades, the Internet has become a routine fixture in everyday life. The popularity of social networking sites, in particular, raises myriad questions regarding identity construction and social interaction. It is also unclear how these practices are related to perceptions of privacy. This dissertation examines how traditional notions of privacy compare, and apply, to privacy on the Internet and considers how issues of power are (re)created in online spaces. By focusing on identity enactment strategies and social connectivity practices, this work sheds light on the ways in which individuals define privacy and choose to …

Global Wreckage And Consumer Illusions: Responses To The Human Effects Of Economic Globalization In Sub-Saharan African Francophone Novels And Films, 1973-2006, Sara C. Hanaburgh

Dissertations, Theses, and Capstone Projects

My study examines a group of nine novels and films set in Ivory Coast, Mali, Senegal, Cameroon and Gabon written and produced between 1973 and 2006 in which "the West" and its international finance network are depicted as the fundamental contemporary world power that wields a destructive dominance over African countries. These forms of control are in many ways similar, yet distinct, from the projects of European imperialism. I analyze consumerism as a major feature of globalization, and discuss the linkage of globalization and the consumer society by looking at various theoretical models, in particular that which Jean Baudrillard conceptualized …

Effects Of Video-Based Peer Modeling On The Question Asking, Reading Motivation And Text Comprehension Of Struggling Adolescent Readers, Kallen E. Tsikalas

Dissertations, Theses, and Capstone Projects

Struggling adolescent readers are distinct from others in two important ways: (1) They are adolescents; and (2) they have a history of struggle with reading.

Good pedagogy prescribes that effective programs "meet students where they are." For middle-school students, this means meeting them in adolescence. Adolescents are more concerned with social norms and more susceptible to peer influence than younger children. Additionally, the fact that these youth are still struggling after years of reading instruction suggests that their motivation to persist at reading is likely to have suffered. To fully support and engage such adolescents, reading programs must leverage social …

Social Aspects Of Developing And Sustaining Voluntarily Reduced Consumption Activity In New York City, Kirsten B. Firminger

Dissertations, Theses, and Capstone Projects

This dissertation examines the social aspects of voluntarily reduced consumption activity using the principles of cultural historical activity theory. Voluntarily buying less is viewed as ongoing interactive social process that is initiated and sustained as individuals engage with their surroundings. Data was collected from 320 online survey respondents living in the New York City Metro area, followed by a purposeful sampling of 24 participants for in-person, follow up interviews. Interviews revealed the social contextual influences on initiating voluntarily reduced consumption activity. For example, family experiences, personal life changes, and historical events played a role in individuals' choice to voluntarily buy …

The Creeks, Beaches, And Bay Of The Jamaica Bay Estuary: The Importance Of Place In Cultivating Relationships To Nature, Kristen L. Van Hooreweghe

Dissertations, Theses, and Capstone Projects

It is often assumed that people living in urban areas lack connections to the natural world and are the source of environmental problems. This assumption, however, is an oversimplification of urban life. Employing an eco-ethnography, with participant observations, qualitative interviews, and an environmental history, this study examines New York City's Jamaica Bay estuary and surrounding neighborhoods to understand how residents cultivate their relationships to nature in a dense urban setting. Many residents near Jamaica Bay have developed a strong connection to place that is rooted in their regular, embodied experiences living, working, playing, and praying on the Jamaica Bay estuary. …

The Museum Of Modern Art's "What Is Modern?" Series, 1938-1969, Jennifer Tobias

Dissertations, Theses, and Capstone Projects

Between 1938 and 1969, the Museum of Modern Art (MoMA) poses the question of What Is Modern? (WIM) in a series of books, traveling exhibitions, and a symposium. This dissertation argues for the WIM project as a sustained if minimally effective effort to influence popular American perceptions of modern art, architecture, and design, at the same time embodying tensions inherent to the museum and its notions of that modernism.

MoMA is an unquestionable influence on modern art history. WIM is a significant component of this influence, yet scholarship on the series is minimal. Hiding in plain sight, the series offers …

Strategic Citizenship: Dual Marginalization And Organized Transnational Political Mobilization Among Ecuadorian And Dominican Migrants, Howard Caro-Lopez

Dissertations, Theses, and Capstone Projects

What factors define transnational political participation and citizenship for contemporary migrants? This dissertation focused on how and why migrant activists from Ecuador and the Dominican Republic pursued political engagement, how their home country governments influenced migrants‘ political activities, and how migrant organizations shaped their transnational activities. The study found that transnational political participation among these two populations was driven by a dual marginalization narrative, where migrants draw from their personal experiences to conclude that they are marginalized in both the U.S. and in their countries of origin based on their status as migrants. Ecuadorian and Dominican political organization leaders use …
