A Structural Model Of Taxation And Unemployment Insurance On Search Dynamics, Yoo Bin Kim

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

The thesis studies the effects of taxation and Unemployment Insurance program on the labor market search and employment dynamics of high school graduates in the U.S. We develop a dynamic life-cycle model of job search with institutional features of taxes and UI benefits, and examine the interaction between them to derive the effects on the optimization problem of single agents; labor force participation decisions, consumption, asset accumulation, labor status transitions, welfare, and the reservation wage. Knowing the effect of taxation and unemployment benefit is twofold and theoretically ambiguous, we estimate the model using a sub-sample of the National Longitudinal Survey …

Existence Of Undominated Subgame Perfect Equilibrium In Extensive Form Games, Ceren Yilmaz

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

There are games for which all subgame perfect equilibria are such that some (or all) players use weakly dominated strategies. Surely this is undesirable as it diminishes the credibility of equilibria. It is implausible to expect a player to play a weakly dominated strategy just because it is an 'equilibrium strategy'. We focus on the class of finite extensive form games with complete and perfect information and show that in this class of games there exists an undominated subgame perfect equilibrium; a subgame perfect equilibrium in which no player uses a weakly dominated strategy. The results also provide insight as …

The Impact Of The Responsiveness Of Monetary Policy On The Housing Market, Lin Zhang

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

Taylor (2007) claims that a not too responsive monetary policy was responsible for the housing boom between 2001 and 2005 and the subsequent financial crisis because it results in the low interest rate during 2002-2004. Using a reduced form model, he shows that the economic situation would have been improved if a more responsive monetary policy had been implemented. In this paper, we set up a two-sector New Keynesian DSGE model, estimated using Bayesian techniques, to evaluate Taylor's hypotheses. First, we did identify a less responsive monetary policy after 2000. Our results partially support Taylor's hypothesis, that a more responsive …

Multi Agent Systems For Cooperative Tracking, Jonathan Patrick Beaudeau

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

This dissertation is a culmination of research in several parallel, yet related avenues dealing with statistical estimation in the context of dynamic state tracking. The main contribution of the thesis is to provide a novel scalable framework for tracking of a high-dimensional target state using a distributed and cooperative network of agents. This framework is incorporated into a specific application consisting of a multiple target tracking (MTT) environment, with each agent employing a number of mobile received-signal-strength (RSS) sensors capable of collecting measurements revealing localized information regarding the target state environment. The dimensionality of this problem, which is the dominating …

On The Design Of High Performance Data Center Networks, Zhiyang Guo

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

Massive modern data centers consisting of tens of thousands of servers have emerged to form the backbone of a variety of powerful distributed computing frameworks, in which efficient communication is often required among huge data sets stored in tens of thousands of servers across a data center. This renders the performance of the data center network (DCN) essential to the successful operation of a data center. This dissertation focuses on several important issues in the design space of high performance data center networks. First, we present a systematic study on optical packet switch, which is a key component in next …

Reconfigurable Architecture For Mixed Processing Elements With Buffer Based Representation, Sumit Suresh Tiwari

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

Modern reconfigurable logic devices are often multi-core and multi-processor architectures with complex intra-processor logic. To fully utilize the raw power of these devices is an arduous task; mapping design data-flows to such devices in a way that will maximize their performance involves careful consideration of a number of parameters, and is the subject of a good amount of research. This thesis presents a novel design, which uses the technique of buffer-based dataflow, a representation technique for realizing data-centric applications in reconfigurable platforms, to map complex logic systems with multiple processing elements to a reconfigurable target architecture having multi-core processors or …

Signature Search And Computing Cost Optimization In Distributed Load Networks, Zhongwen Ying

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

A signature is a data pattern of interest in a large data file or set of large data files. Such signatures that need to be found arise in applications such as DNA sequence analysis, network intrusion detection, biometrics, large scientific experiments, speech recognition and sensor networks. Related to this is string matching. More specifically we envision a problem where long linear data files (i.e flat files) contain multiple signatures that are to be found using a multiplicity of processors (parallel processor). This paper evaluates the performance of finding signatures in files residing in the nodes of parallel processors configured as …

A Novel Analysis Method For Parallel Processing, Zhemin Zhang

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

Though the divisible load scheduling problem has been studied for over two decades, the optimal solution for this problem can be obtained only in a few network topologies by the approach proposed in [6], which recursively equates multiple processing nodes in the network to a super processing node. The limitation of this equivalent approach lies in the fact that a node is required to finishing receiving load from its neighboring nodes simultaneously under this approach, such that linear equations can be established for all nodes in the network. However, the requirement is satisfied in very few network topologies. In this …

A Teacher's Response To Response, Karen Larson Buechner

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

This study is an examination of instructional practices teachers implement during the drafting and revision process and contends that armed with knowledge of how a student responds emotionally and intellectually to these comments, a teacher can have a lasting impact on a writer's development. To that end, it is critical for the teacher to possess deep knowledge of response protocols and conferencing techniques in order for students to generate and refine their ideas. Areas of investigation include the relationship between response methods and writing improvement, the type and mode of comments that facilitate improvement, measurement of the effect of response …

Improvising In The Writing Classroom: How Improvisational Acting Transforms Invention In Social And Collaborative Contexts, Lauren Esposito

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

When mapped onto writing classrooms, improvisational acting provides students with an emphasis on communal ways of knowing that are not restricted to print alone. Improvisational theater promotes the use of multiple literacies, such as kinesthetic, visual, spatial, and aural intelligences, which supplement conventional print-based strategies in writing instruction. Through speaking, listening, and moving, students collectively produce a text--an improvised performance--that stems from the spontaneous interactions and multiple perspectives of an ensemble. In " Improvising in the Writing Classroom: How Improvisational Acting Transforms Invention in Social and Collaborative Contexts," I argue that employing improv techniques and principles in writing pedagogies advances …

A Necessary Death In King Lear, Hyewon Jin

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

This paper looks at King Lear and its tragic ending. Shakespeare's King Lear is based on various accounts, but interestingly he changes from the happy endings of his sources into his own tragic ending by putting Lear and Cordelia to death. This tragic ending has been criticized, but no one could be certain why Shakespeare ends his play in the way he does, especially why he makes Cordelia die. As a result, many critics tried to discover why Cordelia dies in the end. This paper will analyze the various criticisms on Cordelia's death, and show the opposing views of critics' …

Canonical Forest, Yu-Chuan Chen

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

In this dissertation, we propose a new classification ensemble method named Canonical Forest. This new ensemble method uses canonical linear discriminant analysis (CLDA) and bootstrap resampling method to create more accurate and diverse classifiers in an ensemble. Although CLDA is commonly used for dimension reduction, we note here CLDA serves as a linear transformation tool rather than a dimension reduction tool. Since CLDA will find the transformed space that separates the classes farther in distribution, classifiers built on this space will be more accurate than those on the original space. To further diversify the classifiers in an ensemble, CLDA is …

A Current Model For High School Writing Centers, Kimberly Anne Towers

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

Academics across the country seem to agree that there is value in the existence of Writing Centers at the University level, but very few exist at the secondary level. Recent test scores demonstrate that more adequate writing instruction needs to be provided to High School students, and this thesis asserts that a Writing Center can answer this call to action. Through an analysis of the founding of a Writing Center in a High School on Long Island, New York, the author displays the strengths as well as shortcomings of inserting a Writing Center into such an environment. She provides a …

" The Vortex Of Enthusiasm" : Religion And The Making Of American Literature, Lawrence Zellner

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

This dissertation explores how the concept of religious enthusiasm shaped American literature and culture from the Revolution through the Civil War. It traces a new narrative of the relation between literature, religion, and public life in this crucial moment of national formation, as languages and narratives of enthusiasm proliferated across a variety of sites and discourses. The ongoing confrontation between the legacy of Enlightenment and a culture being transformed by the experience of revolution and religious revivalism demanded reconsideration of previous conceptions of normative religious experience and the construction of civil society. In the writings of Charles Brockden Brown, Ralph …

Genetic Contributions To Susceptibility And Resistance To Learned Helplessness, Craig Scott Garafola

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

Depression is a disease with a complex etiology that is only beginning to be studied from a genetic perspective. A selectively bred line of rats, susceptible to the learned helplessness model of depression, presents an opportunity to search for genes affecting either the depressive symptoms or the predisposition towards developing the disease. A microarray revealed a small set of genes with altered expression in the hippocampus of the congenitally helpless rats. We selected one of these genes, a member of the γ -protocadherin family, for further study to determine the basis for the change in expression. Helpless animals demonstrated an …

L-Asparaginase Ii Produced By S. Typhimurium Inhibits T Cell Responses Through Hydrolysis Of L-Asparagine And Suppression Of Metabolic Reprogramming, Annmarie Torres

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

Salmonella enterica serovar Typhimurium (S. Typhimurium) are pathogenic bacteria that suppress T cell responses to avoid clearance by the immune system, yet the mechanisms that mediate this immunosuppression remain largely unknown. Our laboratory previously showed that L-Asparaginase II produced by S. Typhimurium inhibits T cell responses and mediates virulence. The goal of my dissertation research was to determine the mechanism by which L-Asparaginase II produced by S. Typhimurium inhibits T cell responses. As described in my dissertation, I have found that L-Asparaginase II of S. Typhimurium exhibits L-asparagine hydrolysis activity and that this activity is required for the inhibition of …

Observability-In-Depth: An Essential Complement To The Defense-In-Depth Safety Strategy In The Nuclear Industry, Francesca Favaro, Joseph Saleh

Faculty Publications

Defense-in-depth is a fundamental safety principle for the design and operation of nuclear power plants. Despite its general appeal, defense-in-depth is not without its drawbacks, which include its potential for concealing the occurrence of hazardous states in a system, and more generally rendering the latter more opaque for its operators and managers, thus resulting in safety blind spots. This in turn translates into a shrinking of the time window available for operators to identify an unfolding hazardous condition or situation and intervene to abate it. To prevent this drawback from materializing, we propose in this work a novel safety principle …

Thermal Stress And Predation Risk Trigger Distinct Transcriptomic Responses In The Intertidal Snail Nucella Lapillus, Nathaniel D. Chu, Luke P. Miller, Stefan T. Kaluziak, Geoffrey C. Trussell, Steven V. Vollmer

Faculty Publications, Biological Sciences

Thermal stress and predation risk have profound effects on rocky shore organisms, triggering changes in their feeding behaviour, morphology and metabolism. Studies of thermal stress have shown that underpinning such changes in several intertidal species are specific shifts in gene and protein expression (e.g. upregulation of heat-shock proteins). But relatively few studies have examined genetic responses to predation risk. Here, we use next-generation RNA sequencing (RNA-seq) to examine the transcriptomic (mRNA) response of the snail Nucella lapillus to thermal stress and predation risk. We found that like other intertidal species, N. lapillus displays a pronounced genetic response to thermal stress …

Climate Change Enhances The Negative Effects Of Predation Risk On An Intermediate Consumer, Luke P. Miller, Catherine M. Matassa, Geoffrey C. Trussell

Faculty Publications, Biological Sciences

Predators are a major source of stress in natural systems because their prey must balance the benefits of feeding with the risk of being eaten. Although this 'fear' of being eaten often drives the organization and dynamics of many natural systems, we know little about how such risk effects will be altered by climate change. Here, we examined the interactive consequences of predator avoidance and projected climate warming in a three-level rocky intertidal food chain. We found that both predation risk and increased air and sea temperatures suppressed the foraging of prey in the middle trophic level, suggesting that warming …

Nutrition-Related Conditions Among Children Of Migrant And Seasonal Farmworkers In The United States: Causes And Solutions, Rebecca Halvorson

Food Science and Nutrition

The purpose of this literature review is to determine the prevalence of nutrition-related conditions among children of migrant and seasonal farmworkers (MSFW) compared to national averages, as well as effectiveness of strategies for minimizing any health discrepancies. MSFW live under harsh conditions, engage in long hours of physically demanding labor, and receive insufficient income. Compounding demographic characteristics create insurmountable barriers to quality health care and nutrition education resulting in disproportionately unhealthy children within the MSFW population as compared to the greater US population. The prevalence of overweight, obesity, diabetes mellitus, cardiovascular disease, and numerous infections is higher among MSFW children. …

Flow Compressibility Effects Around An Open-Wheel Racing Car, J. Keogh, G. Doig, S. Diasinos

Aerospace Engineering

A numerical investigation has been conducted into the influence of flow compressibility effects around an open-wheeled racing car. A geometry was created to comply with 2012 F1 regulations. Incompressible and compressible CFD simulations were compared-firstly with models which maintained Reynolds number as Mach number increased, and secondly allowing Mach number and Reynolds number to increase together as they would on track. Results demonstrated significant changes to predicted aerodynamic performance even below Mach 0·15. While the full car coefficients differed by a few percent, individual components (particularly the rear wheels and the floor/ diffuser area) showed discrepancies of over 10% at …

On The Interaction Of A Racing Car Front Wing And Exposed Wheel, S. Diasinos, G. Doig, T.J. Barber

Aerospace Engineering

A numerical investigation of generic open-wheel racing car wing and wheel geometry has been conducted, using original sub-scale experimental data for validation. It was determined that there are three main interactions that may occur, identifiable by the path that the main and secondary wing vortices take around the wheel. Interaction ‘A’ occurs when the main and secondary wing vortices both travel outboard of the wheel; interaction ‘B’ is obtained when only the main wing vortex passes inboard of the wheel; while interaction ‘C’ sees both wing vortices travel inboard of the wheel. The different interactions are achieved when geometric changes …

The Relationship Between Tort Reform And Medical Utilization, Kevin T. Kavanagh, Lindsay Calderon, Daniel Saman

Biological Sciences Faculty and Staff Research

NTRODUCTION: The hidden cost of defensive medicine has been cited by policymakers as a significant driving force in the increase of our nation's health-care costs. If this hypothesis is correct, one would expect that states with higher levels of tort reform will have a decrease in Medicare utilization and that medical utilization will decrease after tort reform is enacted.

METHODS: State-level reimbursement data for years 1999 to 2010 (the last year available) was obtained from the Dartmouth Atlas of Health Care. Medical tort rankings for the 50 states were obtained from the Pacific Research Institute (PRI) and correlated with state …

Meiotic Checkpoint Activation Promotes Anaphase Promoting Complex/Cyclosome Substrate Specificity And Ume6/Sin3/Rpd3-Independent Reduction In Emg Expression, Rebecca Lewandowski

Graduate School of Biomedical Sciences Theses and Dissertations

Complex differentiation pathways, such as yeast meiosis and sporulation, are initiated in response to cell type and external stimuli and are driven by changes in tightly regulated and temporally expressed transcriptional programs. These programs are monitored by checkpoint mechanisms that couple meiotic progression to transcriptional activity to ensure each stage is successfully completed prior to progression into the next phase. This work investigated transcriptional regulation controlling meiotic progression when cells sense an insult to genetic integrity. These studies revealed that the early meiotic gene (EMG) repressor Ume6p is degraded during meiotic checkpoint activation triggered by the deoxyribonucleotide reductase inhibitor and …

Employee's Participation: A Critical Success Factor For Justice Perception, Wai Kwan (Elaine) Lau

Accounting Faculty Research

The present study proposed and tested a model that examines the relationship between leadership style, employee’s participation, and justice perceptions. The paper extended the literature of the justice by connecting three major research areas (leadership style, employee’s participation, and organizational justice), and examined the influences of leadership style and employee’s participation in shaping employee’s perception of justice. Results indicated that transactional, transformational, and dynamic leadership have positive impact on distributive, procedural, and interactional justice. Moreover, the effect of leadership style on organizational justice was indirect through employee’s participation. This study synthesized previous leadership studies and argued that leadership style can …

More Evidence For Efficient Markets, Steven D. Dolvin

All Chapters

The market's performance this year has surpassed that of most professional money managers. In fact, this is the worst (relative) year in three decades for professionals (see post here, The Reformed Broker). The level of competition and the high level of fees prevent meaningful outperformance. The result -- a large influx of capital into index funds.
