Development Of A Model Of Participation Of Community-Based, Discretionary Activities By People Who Use Wheelchairs, Anita Perr

Dissertations, Theses, and Capstone Projects

This cross-sectional research analyzed an existing data set of 302 wheelchair users to identify the psychosocial predictors of participation in community-based, discretionary activities. Two defining elements of participation were studied: the extent of participation and satisfaction with participation. Descriptive analyses of the participants' demographic information and portions of four assessments were completed first. Regression analyses were then used to systematically eliminate potential covariates until the significant psychosocial covariates of the extent of and satisfaction with participation were identified. Perceived control over one's life and perceived reintegration to social function were found to predict the extent of participation. Perceived control also …

Roles Of Igh Intronic Enhancer Eμ In Clonal Selection At The Pre-B To Immature B Cell Transition And In The Elimination Of Autoreactive B Cells, Cheng Peng

Dissertations, Theses, and Capstone Projects

The immunoglobulin heavy chain locus (Igh ) intronic enhancer, Eμ, enhances transcription of recombined Igh genes. We have previously shown that in mice with an Eμ-deficient Igh allele (V _H δ^a ), Igμ is expressed at half of the wild-type levels in pre-B cells. We also described an Eμ-dependent "check-point", operating at the pre-B to immature B cell transition, for heavy chain allelic exclusion. We now show that deletion of Eμ results in a smaller immature B cell compartment, and the pre-BCR/BCR signaling is diminished in pre-B cells as a result of the reduced Igμ levels, making it …

Long-Term Warming And The Size And Phenology Of Long Island Sound Plankton, Edward Rice

Dissertations, Theses, and Capstone Projects

In coastal ecosystems with decades of eutrophication and other anthropogenic stressors, the impact of climate change on planktonic communities can be difficult to detect. A time-series of monthly surface water temperatures in the Central Basin of Long Island Sound (LIS) from the late 1940s until 2012 indicates a warming rate of 0.03°C per year, with recent summer temperatures increasing most consistently. During this warming trend, the proportion of chlorophyll produced by smaller phytoplankton and flagellates appears to be higher during warmer summer and fall months, enabling an increase in annual chlorophyll despite static nutrient levels. The phenology of phytoplankton and …

Quantitative Evaluation Of Microglial Activation And Vascularization In Suicide, Tatiana Pavlovna Schnieder

Dissertations, Theses, and Capstone Projects

Accumulated evidence points to immunological factors in psychiatric disorders. In a variety of chronic neurological disorders, exacerbation is associated with inflammation and a loss of integrity of the blood-brain barrier. Microglia, the principal brain immunological cells in the healthy state, respond to changes in the internal environment of the brain through a sequence of activated states. This study compared microglial phenotypes in the white matter of autopsy brains from 11 suicide victims and 25 subjects who died involuntarily. Both groups included cases with and without major psychiatric disorders, which were determined by PA interviews. Cases were matched for sex, age, …

Lipid Dependence In Ras-Driven Tumors, Darin Salloum

Dissertations, Theses, and Capstone Projects

Over past decade, metabolic alterations in cancer cells have received a substantial amount of interest. It had been established that cancer cells undergo a significant amount of metabolic alterations, and some of these alterations are similar to those in normal highly proliferative cells. However, it is becoming more apparent that many of the metabolic alterations are specific to particular oncogenic signaling pathways. Although altered metabolic machinery makes cancer cells more efficient at promoting growth when nutrients are supplied at the sufficient amounts, the dependency of cancer cells on particular metabolic reprogramming deems cancer cells susceptible to disruptions within metabolic network. …

Maniera Devota/Mano Donnesca: Women, Virtue And Visual Imagery During The Counter-Reformation In The Papal States, 1575-1675, Patricia Rocco

Dissertations, Theses, and Capstone Projects

The history of women's participation in religious movements during the Early Modern period in Europe has long been less commented upon in modern scholarship than that of their male counterparts. This project will enlarge our understanding of the participation of women in the visual program of the Counter-Reformation in the Papal State of Bologna. The study focuses on Bologna since the city had an unprecedented large group of active women artists as well as being a crucial site of Catholic reform. Knowledge of Bologna's women is still incomplete; therefore this dissertation is structured as a series of interlinked case studies, …

Existence: An Unholy Trinity. An Account Of Indeterminate Existence, Salas Sanchez-Bennasar

Dissertations, Theses, and Capstone Projects

What is it for something to exist? This dissertation provides an answer to this question by giving a philosophical theory of existence in which the concept of existence in understood as a complex tri-partite notion. The account of existence defended here is arrived at by taking into consideration past philosophical theories of existence, the everyday and scientific uses of the notion, and also philosophical considerations about the nature of reality.

There are three conditions that are central to existence: spatiotemporality, mind-independence, and being a member of the quantificational domain of a true and complete scientific description about the world. To …

Lean, Green, And Lifetime Maximizing Sensor Deployment On A Barrier, Peter Michael Terlecky

Dissertations, Theses, and Capstone Projects

Mobile sensors are located on a barrier represented by a line segment, and each sensor has a single energy source that can be used for both moving and sensing. Sensors may move once to their desired destinations and then coverage/communication is commenced. The sensors are collectively required to cover the barrier or in the communication scenario set up a chain of communication from endpoint to endpoint. A sensor consumes energy in movement in proportion to distance traveled, and it expends energy per time unit for sensing in direct proportion to its radius raised to a constant exponent.

The first focus …

Automated Learner Classification Through Interface Event Stream And Summary Statistics Analysis, Edgar E. Troudt

Dissertations, Theses, and Capstone Projects

Reading comprehension is predominately measured through multiple choice examinations. Yet, as we will discuss in this thesis, such exams are often criticized for their inaccuracies. With the advent of "big data" and the rise of ITS (Intelligent Tutoring Systems), increasing focus will be placed on finding dynamic, automated ways of measuring students' aptitude and progress.

This work takes the first step towards automated learner classification based on the application of graphic organizers. We address the following specific problem experimentally: How effectively can we measure task comprehension via human translation of written text into a visual representation on a computer? Can …

The charge transport property of the organic active layer is one of the key factors to the electronic or optoelectronic performance of devices. Research projects presented in this thesis focused on improving charge carrier mobility of organic charge …

A Cross-Boundary People: The Commercial Activities, Social Networks, And Travel Writings Of Japanese And Taiwanese Sekimin In The Shantou Treaty Port (1895-1937), Lin-Yi Tseng

Dissertations, Theses, and Capstone Projects

This dissertation explores Japanese imperial history in East Asia and focuses on a group of "cross-boundary people"--Taiwanese sekimin (Taiwanese who registered as Japanese subjects) and Japanese--who went to the treaty port of Shantou in southern China during the period between 1895 and 1937. The starting time point (i.e., 1895) corresponds to the signing of the Treaty of Shimonoseki, by which Japan acquired Taiwan as a colony and informal privileges in Chinese treaty ports. The ending time point (i.e., 1937) corresponds to the decline that Shantou's Japanese community experienced owing to the outbreak of the Second Sino-Japanese War on July 7, …

Affective Language And Attitudes Toward Public Policy, Rachel A. Wolitzky

Dissertations, Theses, and Capstone Projects

This dissertation project focused on affective and unconscious processes involved in the evaluation of public policy. It follows recent scholarship in political psychology showing how the response to political messages depends greatly on what values and emotions are evoked. Of particular focus has been the notable discrepancy between the conscious way people construe their political judgments and the unconscious operations that more truly account for their views and actions. Motivated by a neuroscientific and psychoanalytic model of the mind and brain that recognizes both the pre-eminence of unconscious (implicit) processing and the primacy of affect in mind (brain) activity, this …

A Parametrization-Based Surface Reconstruction System For Triangular Mesh Simplification With Application To Large Scale Scenes, Adriana Wise

Dissertations, Theses, and Capstone Projects

The laser scanner is nowadays widely used to capture the geometry of art, animation maquettes, or large architectural, industrial, and land form models. It thus poses specific problems depending on the model scale. This thesis provides a solution for simplification of triangulated data and for surface reconstruction of large data sets, where feature edges provide an obvious segmentation structure. It also explores a new method for model segmentation, with the goal of applying multiresolution techniques to data sets characterized by curvy areas and the lack of clear demarcation features. The preliminary stage of surface segmentation, which takes as input single …

Not By Accident: How Egyptian Civil Society Successfully Launched A Revolution, Helen-Margaret Nasser

Dissertations, Theses, and Capstone Projects

This thesis examines the role of civil society in Egypt and argues that it was central to the success of the 2011 revolution that ended in the ouster of President Hosni Mubarak. I will discuss the development of civil society under Mubarak and demonstrate its strength. In understanding civil society in Egypt, this thesis will discuss the strengths of groups such as associations, Islamist movements, women's groups, labor activism, and youth movements. I also demonstrate that it is important to understand the precedents established that shaped the state's stance towards civil society. As such, this thesis will also discuss the …

From Backlash To Mobilization: Muslim American Prayer Spaces In Post-9/11 New York, George E. Melissinos

Dissertations, Theses, and Capstone Projects

This paper argues that Muslim Americans mobilized against the threat of backlash post-9/11 through the creation of new prayer spaces and maintenance of prayer spaces already in existence before the terrorist attacks. I suggest that the successful mobilization of prayer spaces continues to provide a mechanism of support and unity against backlash for Muslim Americans in New York City since the events of September 11, 2001. I also explore how ineffective mobilization efforts, such as demonstrated by the Park51 project, fail to protect the Muslim American community against backlash.

Chemistry Of 6-Monobrominated Indigo, Mbi, Hiroko Ajiki

Dissertations, Theses, and Capstone Projects

6-monobrominated indigo, MBI, is a component of a historically important and the most expensive colorant, Tyrian Purple.

The colorant is remarkably stable under the sun, in the air and after extensive washing with water. The color is still vivid after thousands of years. Even though it has such a high stability, MBI and Tyrian Purple have color changes from purple to blue upon temperature changes. This color change has been known for long to certain people, but the mechanism of the color change was unknown.

Tyrian Purple also has recently attracted interests for applications towards semiconducting material due to its …

The Neurodevelopment Of Basic Sensory Processing And Integration In Autism Spectrum Disorder, Alice Brown Brandwein

Dissertations, Theses, and Capstone Projects

This thesis presents three studies that together explore the neurophysiological basis for the sensory processing and integration abnormalities that have been observed in autism spectrum disorder (ASD) since the disorder was first described over half a century ago. In designing these studies we seek to fill a hole that currently exists in the research community‟s knowledge of the neurodevelopment of basic multisensory integration -- both in children with autism and as well as in those with typical development. The first study applied event related potentials (ERPs) and behavioral measures of multisensory integration to a large group of healthy participants ranging …

Emotional Expression And Perception In Three Ethnic Groups: Is There An In-Group Advantage?, Ella Björt Teague

Dissertations, Theses, and Capstone Projects

The extent to which emotional recognition is universal or culturally determined has far-ranging implications for the success of cross-cultural communication. Although strong evidence supporting the universality of emotion recognition across differing cultures has accumulated, there is also mounting support for an in-group advantage (Elfenbein & Ambady, 2002a), defined as the ease by which individuals recognize emotions displayed by members of their in-group group compared to out-group members. Due to mixed results from studies focusing on ethnic groups residing within the same country, the current study investigated the in-group advantage among Black American (BAm), Chinese American (CAm), and White American (WAm) …

Scheduling And Resource Allocation In Wireless Sensor Networks, Yosef Alayev

Dissertations, Theses, and Capstone Projects

In computer science and telecommunications, wireless sensor networks are an active research area. Each sensor in a wireless sensor network has some pre-defined or on demand tasks such as collecting or disseminating data. Network resources, such as broadcast channels, number of sensors, power, battery life, etc., are limited. Hence, a schedule is required to optimally allocate network resources so as to maximize some profit or minimize some cost. This thesis focuses on scheduling problems in the wireless sensor networks environment. In particular, we study three scheduling problems in the wireless sensor networks: broadcast scheduling, sensor scheduling for area monitoring, and …

The Music And Multiple Identities Of Kurdish Alevis From Turkey In Germany, Ozan Aksoy

Dissertations, Theses, and Capstone Projects

This dissertation investigates the experiences of Kurdish Alevis, currently living in Germany, who trace their background to locations within the boundaries of the Republic of Turkey. I argue that music has been a particularly important mode through which Kurdish Alevis in Germany have articulated collective histories and have fashioned narratives of belonging and multiple and sometimes contradictory identities. The subjects of my research are immigrants and refugees who are ethnically Kurdish and whose religion is Alevi, an Anatolian religion whose relations to both Sunni and Shi'a Islam are historically controversial. They speak Turkish along with Kurdish, in most cases are …

Computational Insights Into The Oxygen Evolving Complex Of Photosystem Ιι, Muhamed Amin

Dissertations, Theses, and Capstone Projects

The Oxygen Evolving Complex (OEC) of Photosystem II (PSII) is a unique Mn4O5Ca2+ cluster that catalyzes the photoactivated water splitting reaction. The OEC is a model system for bio-inspired artificial systems to use solar energy to pull electrons from water to produce fuel. The OEC goes through a cycle of 5 S states storing 4 holes, via electron transfer to P680+, the primary electron donor in PSII to generate a high valence S4 state that oxidizes water. The key questions are what controls the order of oxidation and deprotonation of the OEC complex and how does the PSII protein modulate …

Supraspinal And Spinal Mechanisms Of Morphine-Induced Hyperalgesia, Caroline A. Arout

Dissertations, Theses, and Capstone Projects

Morphine is the most prominent pharmacological treatment for moderate to severe pain in both acute and chronic paradigms. However, morphine notoriously elicits a paradoxical state of increased pain sensitivity known as hyperalgesia that complicates its use in clinical application. Research over the past three decades has reported that morphine-induced hyperalgesia is dose- and sex-dependent, and likely involves the synchronous activity of several neural networks beyond the opioid system. Whereas systemic, supraspinal, and spinal administration of morphine all cause hyperalgesia that is differentially reversible by N-methyl-D-aspartate receptor (NMDAR) antagonists or melanocortin-1 receptor (MC1R) antagonists, it is unknown as to whether or …

Sovereign Debt And Tax Collection Dynamics In Argentina, Kyle Royal Bauser

Dissertations, Theses, and Capstone Projects

This manuscript examines how the dynamic macroeconomic effects from shocks to taxes and inflation differ between the United States and Argentina. On the fiscal side, wages, private capital, and consumption tax cuts have long-run revenue growth effects (in both countries) that mitigate initial tax receipt losses. These growth effects, however, are larger in Argentina - a country where both the consumption tax rate and sensitivity to wage changes are higher. Specifically, Chapter 2 finds that growth from a U.S. capital tax cut pays for roughly 60% of the initial static loss, whereas the corresponding effect in Argentina is 80%. On …

Diaspora As Development Actors: A Source Of Human And Social Capital For Local Development In Turkey, Meryem Senay Ataselim

Dissertations, Theses, and Capstone Projects

This dissertation provides an analysis of Turkish-American diaspora philanthropy - done through social and human capital transfers - and its role in impacting local development in Turkey. The study offers the consideration of a new kind of diaspora philanthropy, namely innovative philanthropy, which channels ideas, skills and experiences that have the potential to impact social change in local communities through social and human capital transfers.

The dissertation presents and analyzes two cases that have been supported by the Turkish-American diaspora. Case studies show that even though diaspora philanthropy towards Turkey is still relatively new and small in financial terms, there …

The Effects Of Fiscal Policy On Savings And Investment, Andrew A. Bossie

Dissertations, Theses, and Capstone Projects

This dissertation contains three essays exploring the effect of fiscal policy shocks on savings and lending behavior of the private economy. Two essays focus on World War II and one essay focuses on the entire postwar period. Essay I looks at the response of monetary policy to fiscal policy shocks and the effect of fiscal policy on the private sector's balance sheet over a period that covers 1954 and 2007. I find a minimal response of the Federal Reserve to fiscal policy shocks. I also find the the main response of the private sector to fiscal policy shocks manifests itself …

Conformational Features Of The Human U2-U6 Snrna Complex, Ravichandra Bachu

Dissertations, Theses, and Capstone Projects

The splicing of precursor messenger (pre-m) RNA, during which noncoding intervening sequences are excised and flanking coding regions ligated, is an integral reaction of gene expression. In eukaryotes, it is carried out by a dynamic RNA-protein complex called the spliceosome, in which five small nuclear (sn) RNA components are actively involved in recognition and chemical aspects of the process. A complex formed between U2 and U6 snRNAs is implicated in the chemistry of pre-mRNA splicing. The catalytic activity of the U2-U6 snRNA complex is dependent on the presence of Mg2+ ions, and the complex has been shown to have several …

Candida Albicans Als5p Amyloid In Host-Microbe Interactions: A Ceanorhabditis Elegans Study, Michael Bois

Dissertations, Theses, and Capstone Projects

Candida albicans, a dimorphic fungus and an opportunistic pathogen, possesses a myriad of adherence factors including members of the agglutinin-like sequence (Als) family of mannoproteins. The adhesin Als5p mediates adhesion to many substrates, and is upregulated during commensal interactions, but is downregulated during active C. albicans infections[1]. An amyloid forming core sequence at residues 325-331 has been shown to be important for Als5p function, because a single amino acid substitution at position 326 (V326N) greatly reduces Als5p-mediated adherence[2]. We evaluated the role of Als5p in host-microbe interactions, using Caenorhabditis elegans as a host model and feeding them Saccharomyces cerevisiae expressing …

Financial Reporting Differences And Debt Contracting, Anna B. Brown

Dissertations, Theses, and Capstone Projects

I examine the relationship between contracting parties' familiarity with one another's accounting information and the terms and structure of debt contracts. I use the differences in generally accepted accounting principles (GAAP) among contracting parties domiciled in different countries as a proxy for how familiar a lending bank will be with a borrower's accounting information. I find that a larger difference between the GAAP of the lender and the GAAP of the borrower is associated with a higher credit spread and higher fees. I also find that a larger difference between the GAAP of the lender and the GAAP of the …

Collective Memory, Women's Identity And The Church, Jo Ana Elise Brown

Dissertations, Theses, and Capstone Projects

Christianity, Judaism and Islam share a deliberative subjugation of women through ideologies, hierarchical structures and performative practices that effectively relegate women to an inferior position. The Christian tradition has one of the longest-standing and most consistent iconographies with regard to the characterization and status of women in society. The Christian church is prototypical of a religious institution iterating an ideology of women's inferiority through various mechanisms that lodge and preserve it in societal collective memory. This study examines three mechanisms used by the Church to preserve collective memory about women's inferior status in society: doctrine, liturgical practices and visual images …
