Quantification And Control Of Inhomogeneity In Wurtzite (Gan)1-X(Zno)X Semiconductors For Visible Light Absorption, Alexandra Audrey Reinert Dec 2014

Quantification And Control Of Inhomogeneity In Wurtzite (Gan)1-X(Zno)X Semiconductors For Visible Light Absorption, Alexandra Audrey Reinert

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Semiconductors must absorb energy from solar photons and subsequently transport photogenerated electrons and holes to surfaces in order to drive the H2 and O2 formation half-reactions of solar water splitting. The hexagonal wurtzite (GaN)1-x(ZnO)x semiconductor solid solution has produced promising results for visible light solar water splitting, but has yet to achieve an efficiency high enough for practical applications, and the origin of the efficiency limit remains unknown. In this work, a detailed investigation of the average and local structure of these materials has been conducted in order to gain insights into how to improve water splitting efficiencies. Our analysis …

Biophysical Insights Into The Initiation And Inhibition Of Amyloid Formation By Islet Amyloid Polypeptide, Hui Wang Dec 2014

Biophysical Insights Into The Initiation And Inhibition Of Amyloid Formation By Islet Amyloid Polypeptide, Hui Wang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Amyloid formation, the aggregation of normally soluble proteins or polypeptides into highly ordered beta-sheet structures, is a characteristic feature of many human diseases including Alzheimer's disease, Parkinson's disease and type 2 diabetes. I centered my research on islet amyloid polypeptide (IAPP), a neuroendocrine hormone that forms fibrillar amyloid deposits in the extracellular space of the pancreatic islets of Langerhans in type 2 diabetes. Although whether IAPP amyloid formation is a cause or consequence of the disease is controversial, the aggregation process has been shown to induce beta-cell apoptosis and reduce beta-cell mass, which is a hallmark feature of type 2 …

Development And Application Of Chiral Biphenol-Based Diphosphinite Ligands To Pd-Catalyzed Asymmetric Allylic Substitution Reactions, Yang Zang Dec 2014

Development And Application Of Chiral Biphenol-Based Diphosphinite Ligands To Pd-Catalyzed Asymmetric Allylic Substitution Reactions, Yang Zang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In the past decade, libraries of chiral biphenol-based phosphite, phosphoramidite, and diphosphinite ligands have been designed and developed in our laboratory. These ligands are easy to prepare and fine-tunable through modification of the groups at the 3,3'-positions and the substituents attached to the phosphorous atoms. Therefore, our chiral ligand system is suitable for new and specific asymmetric reactions to follow the rapid progress in modern synthetic organic chemistry, e.g. | the asymmetric allylic substitution reactions. As an exploration of the scope of the applications of our chiral ligands, we studied the Pd-catalyzed asymmetric allylic etherification in the most critical step …

The Role Of Parental Involvement In The Social Development Of Children With Autism Spectrum Disorders, Emile Mulder Dec 2014

The Role Of Parental Involvement In The Social Development Of Children With Autism Spectrum Disorders, Emile Mulder

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Autism spectrum disorders (ASD) are characterized by deficits in social interaction. Research with ASD children has dramatically underrepresented fathers, who have only recently been considered as targets for parenting interventions and research. Parenting research with typically developing (TD) children has found that parental involvement (of mothers and fathers) is associated with child social development. Extending such findings to the ASD field is important as social development is a primary concern within this population. The present study sought to do so through an internet questionnaire targeting mothers and fathers. Specifically, this study examined associations between mother involvement, father involvement and their …

The Influences Of Interparental Conflict And Parenting On Children's Social Competence, Nadia Samad Dec 2014

The Influences Of Interparental Conflict And Parenting On Children's Social Competence, Nadia Samad

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Young children's social competence has profound effects on developmental outcomes (Diener & Kim, 2004). It has been well-established that children's home environments (i.e. | parenting, interparental conflict) are related to children's later social competence (O'Connor, Jenkins, Hewitt, DeFries, & Plomin, 2001; Parke et al. | 2001). A structural model was proposed that posited children's social information processing as a mechanism through which interparental conflict and parenting predict children's social competence. To test the proposed model, 397 families with at least one child between the ages of four and eight participated in the present study. The proposed model was analyzed and …

Evidence For Genetic Contributions To Neurobehavioral Traits: Trait Fear/Fearlessness, Behavioral Inhibition, And The Late Positive Potential, Anna Ef Weinberg Dec 2014

Evidence For Genetic Contributions To Neurobehavioral Traits: Trait Fear/Fearlessness, Behavioral Inhibition, And The Late Positive Potential, Anna Ef Weinberg

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Psychiatric disorders are the most common and costly forms of disease and injury worldwide. Despite this, our ability to accurately identify and treat these disorders is limited, due in part to deficient understanding of the underlying mechanisms of dysfunction. The current study aimed to identify genetically-influenced neurobehavioral traits--individual differences evident in both self-report and neural response--that might help improve classification and treatment of mental disorders. Results from event-related potential (ERP) components sensitive to emotional content demonstrated that a) neural processing of emotional content is heritable, b) the heritable traits of heightened trait fear and behavioral disinhibition are associated with unique …

Piratical Designations: Power And Possibility In Representations Of Piracy, Michael D. High Dec 2014

Piratical Designations: Power And Possibility In Representations Of Piracy, Michael D. High

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This dissertation analyzes how designations and representations of piracy define, police, and challenge legitimate production and circulation. From antiquity through the present, the labeling of others as pirates has excluded the less powerful from the authorized distribution of tangible and intangible property. Such discursive exclusion not only defines piracy but also creates it, distinguishing it from other, sanctioned forms of appropriation. This exclusion generates political, legal, and cultural subjectivity, thereby allowing so-called pirates to affect the very discourses and processes from which they are excluded. The first chapter traces the term piracy from its linguistic origin in Ancient Greece to …

Representations Of Gender In Young Adult (Ya) Literature, 1960-2010, Maria I. Cipriani Dec 2014

Representations Of Gender In Young Adult (Ya) Literature, 1960-2010, Maria I. Cipriani

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This dissertation focuses the lens of queer studies and trauma studies on YA literature published in the United States between 1960 and 2010 to demonstrate that authors embed cultural messages in YA texts. Those messages for YA readers intend to model behavior considered appropriate and teach about normative sex and gender roles. Individuals between the ages of 10 and 20 comprise YA readership, and the means of teaching these readers cultural norms include imagery and cautionary tales. The content of the literature inculcates views of acceptable behaviors with respect to sexuality and gender roles and generally conflates sex and gender. …

Performance-Optimized Detection, Tracking And Modeling Of Physical Phenomena In Distributed Sensing Environments, Anurag Umbarkar Dec 2014

Performance-Optimized Detection, Tracking And Modeling Of Physical Phenomena In Distributed Sensing Environments, Anurag Umbarkar

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Cyber Physical Systems (CPS) are distributed systems-of-systems that perform reliable data acquisition in order to build efficient data models. Data models are mathematical expressions that describe the attributes of the observed environments. These models can be used for monitoring, tracking and predicting the dynamics of the physical phenomena. Also, data models aid in formulating decision-making procedures under resource constraints. Data model construction in CPS is challenging because the dynamics of physical environments are hard to track in real-time through a distributed sensing network with limited bandwidth and local memory. Therefore, the limited resources must be optimally utilized to boost performance …

Thermal Emission Spectral Characterization Of Sandstones And Mudstones, Michael Terrance Thorpe Dec 2014

Thermal Emission Spectral Characterization Of Sandstones And Mudstones, Michael Terrance Thorpe

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Thermal emission spectroscopy was used to determine the mineralogy of sandstone and mudstone rocks as part of an investigation of linear spectral mixing between sedimentary constituent phases. With widespread occurrences of sedimentary surfaces on Mars, the critical examination of sedimentary rocks spectral behavior provides a basis for interpreting the environment controlling the mineralogical history of this planet. Unmixing algorithms for thermal infrared rock spectra have previously proven to be a viable technique, with accuracies better than ~17 vol %. However, sedimentary rocks, with natural variation of composition, compaction, and grain size, have yet to be critically examined. In this work, …

Unmasking The Nation: Disputing Of National Myths In The Work Of Cristina García | Unmasking The Nation: Disputing Of National Myths In The Work Of Cristina Garcã­A, Jaimee Lyn Christinat

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This thesis examines the ways in which Dreaming in Cuban, Monkey Hunting and A Handbook to Luck, three novels by Cristina Garcia, contradict and deconstruct popular national myths. In each novel, characters move between nations at key moments in each nation's history. Tracking these individuals' movements within a larger geopolitical framework allows for a new understanding of subaltern migration patterns. In each chapter, a specific aspect of movement is studied illustrating ways in which subaltern people are motivated and/or coerced to move from one nation or another, how their story becomes coopted by the larger national myth and where their …

Millennium Accidents, Breaking Narratives In Pedro Almodã³Var And Alejandro Gonzã¡Lez Iã±Ã¡Rritu | Millennium Accidents, Breaking Narratives In Pedro Almodóvar And Alejandro González Iñárritu, Anna S Shilova

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Millennium Accidents is an attempt to show the relation between the shattered, fragmented and decentralizing nature of contemporary, globalized reality and the texts it produces. In my research I aim to reveal the changes in the building and development of a story as a narrative and cognitive phenomenon. Economic globalization and the high-tech revolution have led to a modification of our mental, emotional and social functioning, converting the whole world into a huge network. Consequently, narrative-- be it verbal or iconic--shows the same metamorphosis as it generates multiple plots, neglects temporal and spatial conventions, and moves beyond national identities. Six …

Consuming Modernity: Photography In Pre-Colonial Korea, 1876-1910, Heejeong Sohn Dec 2014

Consuming Modernity: Photography In Pre-Colonial Korea, 1876-1910, Heejeong Sohn

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Postcolonial studies have successfully unveiled the cultural, social, and political networks of imperial and colonial representations embedded in visual documents of the non-Western world. Within this context, the early photography of Korea has been presented as a cultural force imposed on Koreans in relation to colonialism and Orientalism. This dissertation rethinks the representational politics of early photography during the pre-colonial period of 1876 to 1910 by problematizing the master narratives and suggesting alternative ways to interpret this historical material. Through analyzing the historical contexts of photographic materials and practices, this dissertation argues that photography, as a device of cultural expression, …

The Dp Category And Serbian Nominal Structure, Ivana Laterza Dec 2014

The Dp Category And Serbian Nominal Structure, Ivana Laterza

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This thesis investigates nominal structure in Serbian, focusing on the issue of DP paramaterization. Since the introduction of DP as a syntactic category in the late 1980s (Fukui and Speas (1986), Abney (1987)), various investigators have questioned its universality on the basis of " article-less" languages, such as Japanese and Serbian. Two proposals have emerged. The Universal DP-Hypothesis holds that all languages project DP (Progovac (1998), Rappaport (2001), Basic (2004), Cinque (2005), i.a.). The Parameterized DP-Hypothesis claims that languages without (definite) articles do not project DP (Fukui (1986), Corver (1992), Zlatic (1997), Boskovic (2005), Despic (2011), i.a.). The second view …

Mathematical Modeling Of G-Protein-Coupled Receptor Signaling Pathways, Tao Jiang Dec 2014

Mathematical Modeling Of G-Protein-Coupled Receptor Signaling Pathways, Tao Jiang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

G-protein-coupled receptor (GPCR) signaling plays an important role in converting extracellular stimuli into cellular responses. Many biological functions are regulated by GPCR signaling, and nearly 40\% of current pharmaceuticals target GPCRs. In this work, mathematical modeling is used to investigate the initial steps of GPCR signaling with two major aims: 1) to understand the causes for non-canonical signaling behaviors; 2) to understand how signaling specificity is reacted to in the individual reactions of the pathway. The classic ternary complex model describing the interaction between a single ligand, receptor and G-protein served as our basic model for the initial investigation. Dose …

Software Tools For Stochastic Simulations Of Turbulence, Ryan Kaufman Dec 2014

Software Tools For Stochastic Simulations Of Turbulence, Ryan Kaufman

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

We present two software tools useful for the analysis of mesh based physics application data, and specifically for turbulent mixing simulations. Each has a broader, but separate scope, as we describe. Both features play a key role as we push computational science to its limits and thus the present work contributes to the frontier of research. The first tool is Wstar, a weak* comparison tool, which addresses the stochastic nature of turbulent flow. The goal is to compare underresolved turbulent data in convergence, parameter dependence, or validation studies. This is achieved by separating space-time data from state data (e.g. density, …

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Estuarine organisms are experiencing many stressors related to climate change at an accelerated pace when compared to the open ocean. The co-occurrence of acidification and hypoxia has been observed during warmer months when many fish species spawn in temperate estuaries. Concurrently, estuarine systems can experience extreme temperatures during summer and dynamic levels of plankton. This study assessed the tolerance of early life stage estuarine fish to the co-occurrence of acidification with hypoxia, elevated temperatures, and varying levels of planktonic prey. Time to hatch, hatching rates, survival, and growth were quantified for larval Menidia beryllina, Menidia menidia, and Cyprinodon variegatus exposed …

Population Dynamics Of Juvenile Atlantic Sturgeon, Acipenser Oxyrinchus Oxyrinchus, Within The Northwest Atlantic Ocean, Keith Joseph Dunton Dec 2014

Population Dynamics Of Juvenile Atlantic Sturgeon, Acipenser Oxyrinchus Oxyrinchus, Within The Northwest Atlantic Ocean, Keith Joseph Dunton

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The Atlantic sturgeon, Acipenser oxyrinchus, an anadromous long-lived fish has experienced substantial population declines leading to its recent listing under the Endangered Species Act. While this fish occupies and requires both riverine and marine habitats, a lack of knowledge regarding marine distribution/habitat use is hindering conservation measures directed at restoring depleted populations. Currently, concerns exist that Atlantic sturgeon populations are being hindered by incidental captures along their migrations routes within the near shore coastal fisheries. In order to best manage human activities in a way that populations may recover fully, it is necessary to understand the association between Atlantic sturgeon …
