A Climatology Of Central American Gyres, Philippe Pierre Papin
A Climatology Of Central American Gyres, Philippe Pierre Papin
Legacy Theses & Dissertations (2009 - 2024)
Central American gyres (CAGs) are large, low-level, cyclonic circulations that are observed over Central America during the tropical cyclone (TC) season. CAGs often occur in conjunction with TCs, and can result in torrential rainfall over portions of Central America, the Caribbean Islands, and eastern United States. The lack of prior research on CAGs, their apparent links to TC activity, and their association with high- impact weather motivates this study.
Monitoring Ligand-Induced Nucleic Acid Conformational Changes Using Ion Mobility Spectrometry-Mass Spectrometry, Bill Kenneth Redick
Monitoring Ligand-Induced Nucleic Acid Conformational Changes Using Ion Mobility Spectrometry-Mass Spectrometry, Bill Kenneth Redick
Legacy Theses & Dissertations (2009 - 2024)
Three-dimensional structures of biopolymers frequently dictate the biological role those molecules play. As such, investigation into structure of nucleic acids can provide important information pertaining to how those nucleic acids work. Many nucleic acid species, especially single-stranded RNA, fold into unique structures that allow them to function properly. Metals, and other cationic species, are often bound to the nucleic acid to make folding into the proper structure more favorable by neutralizing the negative charge on the nucleic acid imparted by the phosphate group. This investigation explores tertiary structure of nucleic acids that have been folded in the presence of ligands …
The Peer Environment, Body Dissatisfaction, And Disordered Eating, Erin Elizabeth Reilly
The Peer Environment, Body Dissatisfaction, And Disordered Eating, Erin Elizabeth Reilly
Legacy Theses & Dissertations (2009 - 2024)
Body dissatisfaction has long been implicated as an important etiological factor in the development and maintenance of disordered eating; however, despite the high rates of body dissatisfaction observed within the general population, only a small fraction of individuals develop clinical levels of eating pathology. The current study endeavors to test whether variables related to the peer context may be helpful in better predicting when body dissatisfaction may lead to eating disordered behavior. Undergraduates (N = 500, 63.6% female) completed various questionnaires related to body dissatisfaction, disordered eating, and the peer environment. Results indicated that various types of peer commentary were …

Lithic Analysis Of The Becker Site : Continued Reevaluation Of The Culture-Historic Approach, Christopher Joseph Sobik
Lithic Analysis Of The Becker Site : Continued Reevaluation Of The Culture-Historic Approach, Christopher Joseph Sobik
Legacy Theses & Dissertations (2009 - 2024)
The Becker Site was originally interpreted as a River Phase, Late Archaic central base camp. While excavations at the site yielded numerous Normanskill projectile points, the diagnostic artifact for this phase, several rounds of radiocarbon testing yielded dates firmly in the Woodland Period. A literature review of the history of the use of the culture historic approach in New York State Archaeology, as well as several modern critiques on the same subject was undertaken with the goal of interpreting the site free of its constraints. A lithic analysis of both the formal tools and lithic debitage was undertaken in order …
Power Law Models Of Stock Indices, Mankit Tse
Power Law Models Of Stock Indices, Mankit Tse
Legacy Theses & Dissertations (2009 - 2024)
Viewing the stock market as a self-organized system, Sornette and Johansen introduced physics-based models to study the dynamics of stock market crashes from the perspective of complex systems. This involved modeling stock market Indices using a mathematical power law exhibiting log-periodicity as the system approaches a market crash, which acts like a critical point in a thermodynamic system. In this dissertation, I aim to investigate stock indices to determine whether or not they exhibit log-periodic oscillations, according to the models proposed by Sornette, as they approach a crash. In addition to analyzing stock market crashes in the frequency domain using …
Toward Explaining The Gap : How A Particular View Of Explanation Underwrites The Explanatory Gap, Kimberly Van Orman
Toward Explaining The Gap : How A Particular View Of Explanation Underwrites The Explanatory Gap, Kimberly Van Orman
Legacy Theses & Dissertations (2009 - 2024)
In my dissertation, I consider a common argument for the existence of an unbridgeable explanatory gap between materialism and conscious experience which purports to show that we can determine a priori that conscious experience cannot possibly be explained by a materialist theory. The claim is: no matter what we might yet learn about the brain (or the world), we know enough right now about materialism and explanation to know that an explanation of conscious experience is beyond our reach. I argue that three well-known examples of this position (Jaegwon Kim, David Chalmers, and Joseph Levine) rely on a very narrow …
Factors Influencing The Adjustment Of International Students Enrolled At Public Higher Education Institutions In New York State : An Examination Of Between Group Differences, Jay B. Deitchman
Legacy Theses & Dissertations (2009 - 2024)
This study examines the factors that influence the academic and social adjustment of international students at public higher education institutions in New York State, within both the City University of New York (CUNY) and State University of New York (SUNY) systems. The Achieved Sample was comprised of 503 participants. Five aspects of adjustment to student life were examined: (1) cultural and practical matters; (2) academic expectations; (3) second language communication; (4) near-community and social life; and (5) personal and psychological nature. The Post-Secondary International Student Experience Inventory (PSISEI), an on-line survey instrument developed for this study, was used to gauge …
The Collision Of Political And Legal Time : Foreign Affairs And The Court's Transformation Of Executive Authority, Kimberley Liané Fletcher
The Collision Of Political And Legal Time : Foreign Affairs And The Court's Transformation Of Executive Authority, Kimberley Liané Fletcher
Legacy Theses & Dissertations (2009 - 2024)
A dynamic institutional relationship exists between the United States executive branch and the United States Supreme Court. This dissertation examines how the Court affects constitutional and political development by taking a leading role in interpreting presidential decision-making in the area of foreign affairs since 1936. Examining key cases and controversies in foreign policymaking, primarily in the twentieth and twenty-first centuries, this dissertation highlights the patterns of intercurrences and the mutual construction process that takes place at the juncture of legal and political time. In so doing, it is more than evident that the Court not only sanctions the claims made …
Unpacking The Impact Of Democracy On Terrorism, Issares Lertangtam
Unpacking The Impact Of Democracy On Terrorism, Issares Lertangtam
Legacy Theses & Dissertations (2009 - 2024)
While policy makers assert that democracy can reduce terrorism, academics have produced differing theories explaining the relationship between the two. One theory suggests that democracy discourages terrorism because citizens in democracy can express grievances through electoral process resulting in their less incentive to resort to violence. Another theory argues that democracy encourages terrorism because its enabling environment reduces the cost of terrorist activities. Still another contends that democracy increases terrorism because political contestation in democracy induces some groups to use violence to outbid for their cause. Other strands exist including one suggesting no relationship between democracy and terrorism. These controversial …
Mechanisms Of Age-Related Inflammation And Cancer : The Synergistic Effect Of Oxidants And Calcium, Donald A. Mccarthy
Mechanisms Of Age-Related Inflammation And Cancer : The Synergistic Effect Of Oxidants And Calcium, Donald A. Mccarthy
Legacy Theses & Dissertations (2009 - 2024)
The accumulation of senescent cells during the process of aging has been implicated as causal in numerous age-related pathologies. Senescent cells adopt a secretory phenotype consisting of many factors including matrix remodeling enzymes, growth factors, cytokines, and chemokines. Their secretory nature is the primary reason that they are associated with disease, but it remains unclear why they become so inflammatory. Using primary human fibroblasts cultured to senescence, we mechanistically determined why senescent cells are such potent inducers of inflammation. Our findings indicate that the early production of the cytokine Interleukin 1-α (IL-1α) is central to this transition. We found that …
An Implantable Device For Manipulation Of The In Vivo Tumor Microenvironment, James K. Williams
An Implantable Device For Manipulation Of The In Vivo Tumor Microenvironment, James K. Williams
Legacy Theses & Dissertations (2009 - 2024)
In the past decade, it has become increasingly recognized that interactions between cancer cells and the tumor microenvironment (TME) regulate metastasis. One such interaction is the paracrine loop between macrophages and cancer cells which drives metastatic invasion in mammary tumors. Tumor associated macrophages release epidermal growth factor (EGF), a chemoattractant which induces the migration of cancer cells toward the blood vessels. The cancer cells reciprocate by releasing a macrophage chemoattractant, colony-stimulating factor 1 (CSF-1), resulting in the co-migration of both cell types and subsequent intravasation. In this work, a new technology has been developed for studying the mechanisms by which …
The Effects Of Harsh Parenting And Interparental Aggression Experienced In Youth On The Sympathetic Nervous System, Samantha Aldea Barry
The Effects Of Harsh Parenting And Interparental Aggression Experienced In Youth On The Sympathetic Nervous System, Samantha Aldea Barry
Legacy Theses & Dissertations (2009 - 2024)
The present study examines the link between aggression experienced during childhood and/or adolescence and indicators of the sympathetic nervous system (SNS) during adulthood. Participants completed self-report questionnaires regarding interparental aggression and harsh parenting exposure during childhood and adolescence (155 adults; mean age = 19.0 years old; 76.1% Caucasian/white; 53.5% female). SNS activation was measured by resting skin conductance level (SCL). Results of this study indicate a sex-specific and time-specific pattern of the effects of aggression on SNS activity. Among males, exposure to more harsh parenting in addition to more interparental aggression during childhood is associated with lower resting SCL. Among …

Information Structure, Agreement And Disagreement In English And French Asynchronous Online Discussion, Patrick Rodrigue Belibi Enama
Legacy Theses & Dissertations (2009 - 2024)
This paper compares and contrasts the ways online discussion participants of French and English language expression realize common ground, agree and disagree on newspaper blogs on politics. For that purpose, a corpus of 365 replies among which 177 in French and 188 in English were collected from Le Monde.fr and nytimes.com, the world's two most popular newspaper websites of French and English expression. Kecskes & Zhang's (2009) socio-cognitive approach was used as theoretical framework to analyze common ground. The findings revealed that pragmatic competence, which was put to use depending on the context of situation, was more widely used than …
The Role Of Distress Tolerance And Expectancies In Women's Alcohol Consumption, Cathryn Glanton Holzhauer
The Role Of Distress Tolerance And Expectancies In Women's Alcohol Consumption, Cathryn Glanton Holzhauer
Legacy Theses & Dissertations (2009 - 2024)
The current study explored risk factors for alcohol misuse in women. Past research suggests that negative emotions and stress responsivity may be causally related to alcohol use in women. Based on negative reinforcement models of alcohol use, it was hypothesized that low levels of behavioral distress tolerance (behavioral DT; defined as the ability to persist in goal-directed behavior in the face of psychological distress) may put women at greater risk of alcohol misuse particularly in the context of positive expectancies about the tension-reducing qualities of alcohol. Additionally, the study explored physiological underpinnings of behavioral distress tolerance, and particularly how skin …
The Mediating Effect Of Self-Awareness In The Relations Of Self-Compassion And Training Variables To Therapist Self-Efficacy, I-Ching Grace Hung
The Mediating Effect Of Self-Awareness In The Relations Of Self-Compassion And Training Variables To Therapist Self-Efficacy, I-Ching Grace Hung
Legacy Theses & Dissertations (2009 - 2024)
Therapist self-awareness is widely regarded by educators and clinicians as an essential factor that allows psychotherapists to treat clients effectively (Ridley, Mollen, & Kelly, 2011b). Accordingly, a central goal of therapist training is to increase self-awareness, which is believed to lead to important training outcomes, such as stronger trainee self-efficacy in clinical abilities (e.g., Barnes, 2004; Daniel, Roysircar, Abeles, & Boyd, 2004). Despite this common belief, there is a scarcity of theory and research on the role of self-awareness in affecting therapist training outcomes (Pieterse, Lee, Ritmeester, & Collins, 2013). Using a Social Cognitive Model of Counselor Training (SCMCT; Larson, …
Northeast Cool-Season Cyclones Associated With Significant Upper-Level Easterly Wind Anomalies, Adrian Mitchell
Northeast Cool-Season Cyclones Associated With Significant Upper-Level Easterly Wind Anomalies, Adrian Mitchell
Legacy Theses & Dissertations (2009 - 2024)
A subset of Northeast U.S. cool-season cyclones is associated with upper-level easterly flow and, occasionally, well-defined easterly jet streaks. These events occur approximately once per year and may be associated with retrograding surface cyclones and precipitation caused by northerly warm-air advection, leading to forecast challenges. The deepest extratropical cyclone that affected the Northeast U.S. during the 2009-2010 cool-season was associated with an upper-level easterly jet streak, and produced a record snowfall total of 85 cm in Burlington, Vermont. Orographic precipitation enhancement in this case resulted from an interaction of the low-level flow with the complex topography of northern Vermont. This …
Effective Entity Resolution Methodology For Improving Data Quality And Reliability Of Service-Oriented Applications, Ewa Musial
Legacy Theses & Dissertations (2009 - 2024)
This dissertation proposes new paradigms for improving the testing, reliability of service-oriented applications as well as the quality of data. Since it is difficult to track information flowing through the multiple tiers of an application, testing service-oriented systems can be very challenging. We present a methodology for testing service-oriented applications that takes into account all the components, including services, external services, and data components. The results of our experiments demonstrate that this approach greatly improves the effectiveness of testing service-oriented applications.
Mechanisms Of Dna Synthesis And Fidelity By Y-Family Translesion And C-Family Replicative Polymerases, Purba Mukherjee
Mechanisms Of Dna Synthesis And Fidelity By Y-Family Translesion And C-Family Replicative Polymerases, Purba Mukherjee
Legacy Theses & Dissertations (2009 - 2024)
Since the discovery of the DNA polymerase by Arthur Kornberg nearly 60 years ago, there have been great advances in understanding the involvement of polymerases in replication and repair. Years of genetic, biochemical and structural studies have lead to the classification of DNA-dependent DNA polymerases into six families: A, B, C, D, X and Y. In this work, I have focussed on two different families, C and Y. Hence this work is divided into two parts. Part one discusses the studies on Y-family polymerases. All Y-family polymerases are involved in replicating past DNA lesions. The ability to tolerate unnatural nucleotides …
Momentum And Spin In Entropic Quantum Dynamics, Shahid Nawaz
Momentum And Spin In Entropic Quantum Dynamics, Shahid Nawaz
Legacy Theses & Dissertations (2009 - 2024)
We study quantum theory as an example of entropic inference. Our goal is to remove conceptual difficulties that arise in quantum mechanics. Since probability is a common feature of quantum theory and of any inference problem, we briefly introduce probability theory and the entropic methods to update probabilities when new information becomes available. Nelson's stochastic mechanics and Caticha's derivation of quantum theory are discussed in the subsequent chapters. Our first goal is to understand momentum and angular momentum within an entropic dynamics framework and to derive the corresponding uncertainty relations. In this framework momentum is an epistemic concept -- it …
Condom Use Among Married Women In India, Claire Arielle Nicolas
Condom Use Among Married Women In India, Claire Arielle Nicolas
Legacy Theses & Dissertations (2009 - 2024)
Recent research on HIV/AIDS in India has not focused on married women, although married women have shown increasing rates of infection. This study examines how condom use among married women varies by regional and residential location, and further examines how the variation may be explained by a set of potential mediators. My theories used in this study are Urbanization, Information-Motivation-Behavioral Model, and Gender Theory to capture how society and location may not only provide women with the necessary education about HIV/AIDS prevention, but also motivate them to put that knowledge to use. Using the Demographic and Health Survey for India …

Adult Learners Of English Interacting With Native Speaker Teachers And Non-Native Speaker Teachers : Exploring Differences In Students' Language Use, Melody Hallenbeck Nadeau
Legacy Theses & Dissertations (2009 - 2024)
This mixed-methods study examined the lived experience of adult English Language Learners (ELLs) in classrooms led by native speaking teachers, compared with their experience in classrooms led by non-native teachers. The socio-cognitive approach to language and emergent common ground framed the development of the English classroom as a Community of Practice, in which students produced varying levels of complex, formulaic, metaphorically dense speech.
Analysis Of Mass Fragmentation Patterns Using Dart-Ms And Gcms For Drugs Of Abuse, Teresa Anne O'Neill
Analysis Of Mass Fragmentation Patterns Using Dart-Ms And Gcms For Drugs Of Abuse, Teresa Anne O'Neill
Legacy Theses & Dissertations (2009 - 2024)
Drugs of abuse have been a major problem for law enforcement departments. The structures of the drugs, as well as the ever changing trends in abuse, make it difficult and time consuming to analyze using modern techniques such as GC-MS. DART-MS is a rapid technique that requires no pre-treatment or re-concentration to analyze a sample. Samples of amphetamines, cathinones and cannabinoids were analyzed using DART-MS and GC-MS in order to provide fragment patterns that would make it easier to identify an unknown drug. Using DART-MS, isomers can be differentiated as well as identified rapidly, which is an advantage over GC-MS. …

The Effects Of Lobbying Expenditures On Firm Profitability, Laurie Okinaga
The Effects Of Lobbying Expenditures On Firm Profitability, Laurie Okinaga
Legacy Theses & Dissertations (2009 - 2024)
The effect of lobbying expenditures on firm profitability has been frequently examined but prior research has yielded inconclusive and contradictory findings. This study examines the effect of annual lobbying expenditures by Fortune 500 firms from 1998 to 2011 on Return on Equity (ROE) and Return on Assets (ROA), controlling for the effects of firm, time, industry, and market profitability. The analysis finds no evidence of a relationship between lobbying expenditures and ROA and a weak, negative relationship between lobbying expenditures and ROE. The seemingly contradictory negative relationship between lobbying and ROE may be due to the tendency for large firms …
El Wavering Imaginativo Y La Conciencia Imaginante En Los Cuentos De Marvel Moreno Y Angela Carter, Alejandra Olarte
El Wavering Imaginativo Y La Conciencia Imaginante En Los Cuentos De Marvel Moreno Y Angela Carter, Alejandra Olarte
Legacy Theses & Dissertations (2009 - 2024)
In this dissertation, I explore the short stories of Colombian writer Marvel Moreno and English writer Angela Carter. I propose that the authors' works share a dual conceptualization of the notion of imagination -- imaginative wavering and imagining consciousness. These conceptualizations constitute interpretative frameworks to comparatively examine textual strategies and themes within the authors' works of fiction. A fundamental characteristic of both imaginative wavering and imagining consciousness is movement. With the former, movement implies a constant oscillation between intradiegetic reality and rational thinking, as exposed in the stories. With the latter, movement entails the act of grasping the reality that …
Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne
Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne
Legacy Theses & Dissertations (2009 - 2024)
Recurrent hypoglycemia (RH) occurs with the over administration of insulin resulting in severe hypoglycemia on a repetitive basis. This occurs most commonly among Type I Diabetics who rely on exogenous insulin replacement for management of their disease; however it is becoming increasingly common among Type II Diabetics. Although cognitive deficits are reported during hypoglycemia, the period following restoration of euglycemia has been denoted by improved hippocampally-mediated short-term and working memory in humans and rodents, respectively. RH is also associated with an altered glucocorticoid secretion profile in response to hypoglycemia. In vitro and in vivo approaches were utilized with the goal …
Household Economies : The Production And Consumption Of Plumbate At Miguel AlemáN, The Conquista Campesina Complex And The PiñUela Complex, Marx Navarro-Castillo
Household Economies : The Production And Consumption Of Plumbate At Miguel AlemáN, The Conquista Campesina Complex And The PiñUela Complex, Marx Navarro-Castillo
Legacy Theses & Dissertations (2009 - 2024)
The Soconusco region of Chiapas, Mexico, where the sites of Miguel Alemán, the Conquista Campesina Complex (Conq-18) and the Piñuela Complex (PIN) are located, has been an object of study by archaeologists since the beginning of the nineteenth century. My project focused at this locale is concerned with craft production as related to the organization and the development of hierarchical social relations and how this relationship is reflected through diverse indexes. Although Plumbate ceramics are my principal source of information, I studied other ceramic types as well.
Expanding Applications Of The Nano Intravital Device As A Platform For Exploring Tumor Microenvironments, Michael Padgen
Expanding Applications Of The Nano Intravital Device As A Platform For Exploring Tumor Microenvironments, Michael Padgen
Legacy Theses & Dissertations (2009 - 2024)
The tumor microenvironment has been demonstrated to be a key determinant in the progression of cancer. Unfortunately, the mechanisms behind the different microenvironments (cytokine gradients, hypoxia, hypoglycemia, etc) have not been fully elucidated. Identifying these mechanisms can lead to targeted, individualized therapy to prevent metastasis. The Nano Intravital Device (NANIVID) is a microfabricated, implantable device designed to initiate specific microenvironments in vivo so that the time course of the effects can be observed. With both spatial and temporal control over the induced environments, the affected regions of the tumor can be compared to the rest of the tumor. The NANIVID …
Regulation Of Ty1 Retrovirus-Like Transposon Rna Localization And Translation, Ryan Joseph Palumbo
Regulation Of Ty1 Retrovirus-Like Transposon Rna Localization And Translation, Ryan Joseph Palumbo
Legacy Theses & Dissertations (2009 - 2024)
Replication of the Ty1 retrovirus-like transposon of the yeast Saccharomyces cerevisiae is stringently regulated to reduce the frequency of deleterious retrotransposition events. However, under stress conditions, Ty1 retrotransposition can lead to adaptive genomic alterations. To characterize host regulation of Ty1 retrotransposition, I analyzed ribosome profiling data and showed that Ty1 RNA is efficiently translated. Moreover, the ribosome biogenesis factors BUD21, DBP7, HCR1, LOC1, MRT4, and PUF6 are required for optimal expression of the Ty1 protein Gag.
