The Other Half Of The Protein Folding Equation Characterization Of The Protein Denatured State Ensemble (Dse): The Case Of C-Terminal Domain Of The Ribosomal Protein L9 (Ctl9), Bowu Luan

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

Studies on the unfolded state of proteins are important for understanding the mechanism of protein folding. The protein unfolded state or protein denatured state ensemble (DSE) is the starting point for protein folding. It provides a thermodynamic reference state for protein stability, and it can be targeted by rational protein design. Studies of the properties of DSEs can also reveal the factors that impact protein misfolding and modulate the tendency for protein aggregation in vitro and in vivo, and amyloid formation. The 92-residue C-terminal domain of ribosomal protein L9 (CTL9) is used as a model to study protein DSEs. This …

Synthesis Of Structurally Diverse Major Groove Dna Interstrand Crosslinks, Shivam Mukherjee Dec 2014

Synthesis Of Structurally Diverse Major Groove Dna Interstrand Crosslinks, Shivam Mukherjee

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

DNA Interstrand Cross-links (ICLs) are extremely cytotoxic lesions caused by a variety of endogenous and exogenous agents. ICLs prevent the separation of two DNA strands and hence block essential cellular functions such as DNA transcription and replication. ICL causing agents are widely used in cancer chemotherapy and the removal of ICLs is associated with the resistance to anticancer agents. Despite the clinical importance of ICLs, the details of the pathways by which these lesions are repaired remain poorly understood. This dissertation focuses on the synthesis of structurally diverse major groove DNA ICLs that induce different degrees of distortion into the …

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

Block copolymers consist of two or more homopolymer units linked by a covalent bond. They have attracted great research interest because they can microphase separate to form highly ordered nanostructures. The well-defined nanoscale metal-polymer hybrid materials can be formed through self-assembly and phase separation of alkyne-functional polymers with metal species that can react with the alkyne groups, which may have potential applications for memory storage, energy storage, and biomedical equipment. The focus of this thesis is the synthesis of polystyrene-block-poly(4-(phenylethynyl)styrene) (PS-b-PPES) diblock copolymers as precursors for cobalt-containing materials. Polystyrene-block-poly(4-(phenylethynyl)styrene) (PS-b-PPES) diblock copolymers were synthesized at a variety of PS/PPES ratios …

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 …

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 …

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 …

Performance Optimization In Large-Scale 802.11n Wireless Local Area Networks, Dawei Gong

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

Recently, wireless local area networks (WLANs) have become an indispensable part of our daily life. To enhance the rate, range and reliability of WLANs, the IEEE 802.11n standard has introduced several new technologies, such as multiple input multiple output (MIMO), channel bonding and frame aggregation. However, the performance of WLANs is often unsatisfactory. In this dissertation, we study performance optimization in large-scale 802.11n WLANs, aiming at improving network throughput, reducing transmission failures, and enhancing the reliability and efficiency of link-layer multicast. In WLANs, clients need to associate with an access point (AP) to access the network. An AP and its …

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 …

A Study Modeling Secure Base Parenting Cognitions, Sandra Skinner Dec 2014

A Study Modeling Secure Base Parenting Cognitions, Sandra Skinner

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

Secure attachment is associated with a host of positive outcomes including higher levels of prosocial behavior and self-efficacy, better stress regulation, and a lower incidence of psychopathology. Secure base support and sensitive caregiving interactions are predictive of secure attachment. Interventions designed to promote sensitive caregiving have had success in both improving parental behaviors and in increasing levels of attachment security. These interventions are, however, too time consuming and resource intensive to be rolled out to the general population. This study sought to determine if a brief and easy to deliver intervention could be successful in enhancing secure base cognitions in …

Family Education, Occupation, And Chronic Illness: Social Class And The Lives Of Hemodialysis Patients, Paul Eric Bugyi Dec 2014

Family Education, Occupation, And Chronic Illness: Social Class And The Lives Of Hemodialysis Patients, Paul Eric Bugyi

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

A vast amount of evidence exists showing a relationship between socioeconomic status (SES) and health. Regardless of how outcomes are measured (self-reported health, incidence of disease, mortality rates and others), income, educational attainment, and occupation are key predictors. How SES matters for health outcomes has been a major question asked by researchers during the past 25 years. Many sociologists argue that the resources that come along with high socioeconomic status - money, power, prestige, beneficial social connections, knowledge, and skills - explains the SES/health gradient. This research project assesses whether or not those resources were important to individuals in dealing …

Gender, Power, And Inequality: An Examination Of The Causes And Consequences Of Queer Intimate Partner Violence, Bethany Marie Coston Dec 2014

Gender, Power, And Inequality: An Examination Of The Causes And Consequences Of Queer Intimate Partner Violence, Bethany Marie Coston

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

Violence is a not a new social phenomenon--at least, in the sense that violence has occurred throughout history between individuals, within communities, and practiced by institutions. But mainstream sociological studies of violence are all too often studies of men's violence. This project is an attempt to challenge critically the specter of heteronormativity that haunts the theories and praxis of intimate partner violence (IPV). Under this preexisting framework, studies have focused on men's violence against woman and used patriarchy as an explanation (i.e. the unequal distribution of gendered power, with men benefiting). However, I want to know if gender is still …

Seeking Common Ground In The Abortion Regulation Debate, Jessica Arden Ettinger Dec 2014

Seeking Common Ground In The Abortion Regulation Debate, Jessica Arden Ettinger

Notre Dame Law Review

This Note argues that requiring abortion clinics to adhere to the same standards as ambulatory surgical centers is unconstitutional, at least in the context of those clinics that provide only medication abortion, because it unduly burdens a woman’s right to choose whether to obtain an abortion. Although there may be a rational basis to require abortion clinics offering surgical abortion procedures to meet surgical facility standards, no such basis attends the imposition of those requirements on clinics that provide nonsurgical services. Given the number of clinics that continue to close in the face of this new regulatory legislation—which significantly reduces …

Amending Equal Time: Explaining Institutional Change In American Communication Policy, Tim P. Vos, Seth Ashley Dec 2014

Amending Equal Time: Explaining Institutional Change In American Communication Policy, Tim P. Vos, Seth Ashley

Communication Faculty Publications and Presentations

This study explains the history of a 1959 amendment to the 1934 Communications Act through the lens of historical institutionalism. The amendment created broad exemptions for newscasts, documentaries, interviews, and news events, triggering the equal time provision for candidates for public office. While this study offers a variety of new empirical details, the chief goal is explanation based on an examination of historical mechanisms—path dependence, critical junctures, agglomeration, asymmetries of power, reinforcement of expectations, and temporal sequencing—that shaped the policy options leading up to the amendment.

Growth And Biomass Accumulation Of Komatsuna Greens As Affected By Nutrient Solution Electrical Conductivity, Leah P. Malvar Dec 2014

Growth And Biomass Accumulation Of Komatsuna Greens As Affected By Nutrient Solution Electrical Conductivity, Leah P. Malvar

Horticulture Undergraduate Honors Theses

The affects of different nutrient concentrations on komatsuna (Brassica rapa var. perviridis 'Komatsuna') grown in a nutrient film technique (NFT) hydroponic system were observed. Nutrient concentrations, measured by electrical conductivity (E.C.) in mS/cm, influenced plant height, leaf area, and plant fresh weight. The lowest measurements for each of these parameters were observed at the lowest E.C. of 1.0. mS/cm. As E.C. was increased from 1.0 to 1.2 mS/cm, measurements for shoot fresh weight and shoot height trended higher. Total leaf area increased as the E.C. was increased from 1.0 to 1.4 mS/cm, decreased as the E.C. was increased up to …
