Occupy Mall Street? How The Court Conditioned Public Space Where People Go, Anthony Maniscalco

Dissertations, Theses, and Capstone Projects

This thesis explores the tension between practicable space and property rights. That tension has frequently animated legal contests over political expression in privately owned, publicly accessible marketplaces in the United States. Do American marketplaces function as marketplaces of ideas? Should they? In order to examine those questions, I survey the Supreme Court's considerations of expressive activity on public and commercial property, in particular, shopping centers. I begin by developing indications of public space, as well as noting the challenges for civic inclusion within the modern political sphere. Next, I survey historical practices of public space within (Western) marketplaces. Those practices …

In And Out Of Uniform: The Transition Of Iraq And Afghanistan War Veterans Into Higher Education, Vienna Messina

Dissertations, Theses, and Capstone Projects

IN AND OUT OF UNIFORM:

THE TRANSITION OF IRAQ AND AFGHANISTAN WAR VETERANS INTO HIGHER EDUCATION

by

Vienna Messina

Advisor: Professor Colette Daiute

With the exit of US combat troops from Iraq in 2011 and the subsequent drawdown of forces in Afghanistan, much public attention became focused on the reintegration of veterans of these wars into all aspects of civilian life. Record numbers of returning veterans enrolled in higher education. Abramson (2012) reported that, since 2009, when the Post-9/11 GI Bill became effective, more than 860,000 Iraq and Afghanistan veterans had used its generous provisions for further education and projected …

Nature's Goodness: An Aristotelian Account, Nathan K. Metzger

Dissertations, Theses, and Capstone Projects

Neo-Aristotelians have made major headway in moral theory, and it is now commonplace to find philosophers defending the reality of goodness through a teleological analysis of human being. Whatever the merits of this approach, it has suffered from a lack of a sustained defense of its pre-modern metaphysical panorama: the Aristotelian conception of the human good gets traction only if its decidedly pre-modern and `robust' philosophy of nature is defensible in its own right. In this dissertation, I aim to give a partial breakdown of the particular sort of metaphysical project that the Aristotelian moral theorist assumes, but does not …

Reliability-Based Progressive Collapse And Redundancy Analysis Of Bridge Systems, Feng Miao

Dissertations, Theses, and Capstone Projects

Highway bridges like most structural systems are usually designed on a member by member basis and little consideration is provided to the effect of a local failure on system safety. There are concerns that some systems optimized to meet code-specified member design criteria may not provide sufficient levels of structural redundancy to withstand a possible local failure. In fact, a local failure of one structural element may result in the failure of another element creating a chain reaction that might progress throughout the whole structure or a major portion of it leading to a catastrophic collapse. Several recent catastrophic structural …

Why Should One Reproduce? The Rationality And Morality Of Human Reproduction, Lantz Fleming Miller

Dissertations, Theses, and Capstone Projects

Human reproduction has long been assumed to be an act of the blind force of nature, to which humans were subject, like the weather. However, with recent concerns about the environmental impact of human population, particularly resource depletion, human reproduction has come to be seen as a moral issue. That is, in general, it may be moral or immoral for people to continue propagating their species. The past decade's philosophical discussions of the question have yielded varying results. This dissertation takes on the issue in a broader moral perspective and asks not only whether it is moral to reproduce but …

Conditional Discriminative Functions Of Meaningful Stimuli And Enhanced Equivalence Class Formation, Roxana I. Nedelcu

Dissertations, Theses, and Capstone Projects

Two experiments explored how the formation of two 3-node, 5- member equivalence classes by college students was influenced by the prior acquisition of conditional discriminative functions by one of the abstract stimuli, designated as C, in the class. In Experiment 1, participants in the GR-0, GR-1, and GR-5 groups attempted to form classes after mastering 0, 1 or 5 conditional relations between C and abstract stimuli that were not included in the to-be-formed classes. Participants in the GR-many group attempted to form classes that contained four abstract stimuli and one meaningful, familiar picture that served as the C stimulus. In …

Intracellular Mechanisms Associated With Cocaine Induced Conditioned Place Preference, Stephanie K. Nygard

Dissertations, Theses, and Capstone Projects

The aim of this dissertation was to investigate the intracellular responses associated with the acquisition and expression of cocaine-context associations. ERK (extracellular regulated kinase), CREB (cAMP responsive element binding protein), FosB and deltaFosB proteins were of particular interest due to their involvement in cocaine reward and in synaptic plasticity underlying learning and memory. We used the conditioned place preference (CPP) paradigm, which employs a Pavlovian conditioning procedure to establish an association between a drug-paired environment and the drug's rewarding effects, to study the role of these signaling pathways in cocaine-context associations. N-methyl-D-aspartate receptor (NMDAR) antagonism prior to cocaine administration during …

On The Role Of Neuronal Oscillations In Auditory Cortical Processing, Monica Noelle O'Connell

Dissertations, Theses, and Capstone Projects

Although it has been over 100 years since William James stated that "everyone knows what attention is", its underlying neural mechanisms are still being debated today. The goal of this research was to describe the physiological mechanisms of auditory attention using direct electrophysiological recordings in macaque primary auditory cortex (A1). A major focus of my research was on the role ongoing neuronal oscillations play in attentional modulation of auditory responses in A1.

For all studies, laminar profiles of synaptic activity, (indexed by current source density analysis) and concomitant firing patterns in local neurons (multiunit activity) were acquired simultaneously via linear …

Colloidal Quantum Dot Based Photonic Circuits And Devices, Nicky E. Okoye

Dissertations, Theses, and Capstone Projects

Colloidal quantum dots have desirable optical properties which can be exploited to realize a variety of photonic devices and functionalities. However, colloidal dots have not had a pervasive utility in photonic devices because of the absence of patterning methods. The electronic chip industry is highly successful due to the well-established lithographic procedures. In this thesis we borrow ideas from the semiconductor industry to develop lithographic techniques that can be used to pattern colloidal quantum dots while ensuring that the optical properties of the quantum dots are not affected by the process. In this thesis we have developed colloidal quantum dot …

The Meaning, Experience, And Value Of 'Common Space' For Women And Children In Urban Poor Settlements In India, Anupama Reddy Nallari

Dissertations, Theses, and Capstone Projects

Housing and basic services in urban poor settlements have been the focus of bi-lateral agencies, national governments as well as NGOs and CBOs. However, little attention has been paid to understanding the value of "common spaces" in these settlements, or in the planning and design of "common spaces" in upgraded or redeveloped settlements. Common spaces include communal areas like childcare and play facilities, religious and cultural establishments, shops, physical infrastructure like roads and sanitation, and informal spaces like courtyards, steps, lanes, and corridors where women perform daily chores and interact and children play. This dissertation focuses on understanding the significance …

Teachers At Work: Factors Influencing Satisfaction, Retention And The Professional Well-Being Of Elementary And Secondary Educators, Patrick Edward O'Reilly

Dissertations, Theses, and Capstone Projects

The purpose of this study has been to explore the question of how factors in the work lives of teachers influence their experience of workplace satisfaction, and how satisfaction influences retention in the teaching profession. This study had three specific goals: (1) to examine whether five specified factors that teachers' encounter as workers influence their professional satisfaction, (2) to explore whether teacher satisfaction influences retention in the profession and (3) to determine whether school level taught plays a role in degrees of satisfaction a teacher experiences.

Data was collected over a period of five months, using a survey administered to …

Melodic Function And Modal Process In Gregorian Chant, Richard Porterfield

Dissertations, Theses, and Capstone Projects

This study proposes a theory and method of analysis for voice leading in the melody of Gregorian chant. It draws on historical theories and practices, particularly those of the cantus tradition which 1) pre-dates the imposition on Western ecclesiastical chant of scale theories based in the Ancient Greek science of harmonics, 2) observes and predicts actual melodic behavior, and 3) remains basic to pedagogy through the centuries. Central to cantus-tradition doctrine is the investment of melodic tones with structural functions which articulate modes as melodic archetypes; idiomelic antiphons are analyzed according to five melodic functions derived from formulaic psalmody …

Engaging Bad Governments: Resource Groups And Patterns Of Engagement In Bangladesh, Nayma Qayum

Dissertations, Theses, and Capstone Projects

Bangladesh's governments have pursued an aid-based neoliberal development agenda since the 1980s, which has allowed new resources and non-governmental organizations (NGOs) to permeate rural society. These NGOs operate programs through resource groups, small groups of impoverished women who gather at the village or ward levels. This dissertation argues that resource groups have built new citizen-state relationships and enabled new forms of engagement between citizens and their governments. These new transactional relationships are governed simultaneously by informal institutions of accountability and informal institutions of exchange; the former allow actors to reinforce formal rules when badly-performing institutions deviate from them, and the …

Comparative Modeling And Functional Characterization Of Two Enzymes Of The Cyclooxygenase Pathway In Drosophila Melanogaster, Yan Qi

Dissertations, Theses, and Capstone Projects

Eicosanoids are biologically active molecules oxygenated from twenty carbon polyunsaturated fatty acids. Natural eicosanoids exert potent biological effects in humans, and a great deal of pharmaceutical research has led to the discovery of compounds for selective inhibition of specific enzymes in eicosanoid biosynthesis. Coupled with different receptors, eicosanoids mediate various physiological and pathophysiological processes, including fever generation, pain response, vasoconstriction, vasodilation, platelet aggregation, platelet declumping, body temperature maintenance and sleep-wake cycle regulation. In mammals, the eicosanoid biosynthesis has three pathways: the cyclooxygenase (COX) pathway, the lipoxygenase (LOX) pathway and the epoxygenase pathway. The COX pathway synthesizes prostanoids, which are important …

Women's Experiences Of Privacy, Publicness And Place In Mediated Space, Nelida Quintero

Dissertations, Theses, and Capstone Projects

This mixed-method study explored the experiences and understandings of the notions of privacy, publicness and place in mediated space among women who use the internet daily. Mediated space is experienced at the intersection of mass media, including the internet, and the physical environment. In this two-phased study, fourteen women were interviewed and sixty-one completed an online survey. Participants were asked about the physical places they preferred and the activities they undertook, whether for paid work, domestic work or entertainment, such as sending e-mails and gathering information, posting or reading posts on social network sites, shopping, banking, web browsing, watching TV …

"A New Way Of Doing Politics": The Movement Against Cafta In Costa Rica, Jeremy Rayner

Dissertations, Theses, and Capstone Projects

In October of 2007, Costa Ricans voted in a referendum to ratify a Free Trade Agreement with the United States (DR-CAFTA, or CAFTA). The first referendum in their nation's history--and the first referendum ever held on a Free Trade Agreement--marked the culmination of a cycle of contention over liberalization that transformed practices and expectations of politics in a country often considered an exemplar of representative democracy. In this dissertation I provide an account of the opposition to CAFTA (the NO), based on two years of ethnographic research with the Patriotic Committees (Comites Patrioticos), the decentralized, grassroots network at the heart …

Becoming Transnational Citizens: The Liberian Diaspora's Civic Engagement In The United States And In Homeland Peacebuilding, Janet Elizabeth Reilly

Dissertations, Theses, and Capstone Projects

This study examines the relationship between civic participation in homeland peacebuilding and immigrants' political incorporation and integration in their local communities in the United States. It explores the impact of state (U.S. and Liberia) policies and local context on individuals' civic participation locally and in transnational activities. The study demonstrates the mechanisms through which state policies and local context influence Liberians' political participation in the United States and their transnational citizenship, defined as full legal membership and civic participation. The relationship between civic engagement in the United States and in transnational activities is not an adversarial one. Engagement with the …

Neurophysiological Bases Of Frequency Discrimination In Children With Auditory Processing Disorder Or Specific Language Impairment, Christine Rota-Donahue

Dissertations, Theses, and Capstone Projects

The purpose of this study was to determine if 10-12 year old children with Auditory Processing Disorder (APD) or Specific Language Impairment (SLI) could discriminate three different frequency changes behaviorally and electrophysiologically. Behavioral frequency discrimination and event-related potentials were examined using a 1000Hz pure tone base frequency. Typically developing children and children with APD or SLI differed in in their detection of frequency changes: behavioral results were below chance level and the MMN amplitude was smaller in the impaired population. Slight differences between children with APD and children with SLI were also found that might shed light on the controversy …

Metabolic Checkpoints In Cancer Cell Cycle, Mahesh Saqcena

Dissertations, Theses, and Capstone Projects

Growth factors (GFs) as well as nutrient sufficiency regulate cell division in metazoans. The vast majority of mutations that contribute to cancer are in genes that regulate progression through the G1 phase of the cell cycle. A key regulatory site in G1 is the growth factor-dependent Restriction Point (R), where cells get permissive signals to divide. In the absence of GF instructions, cells enter the quiescent G0 state. Despite fundamental differences between GF signaling and nutrient sensing, they both have been confusingly referred to as R and therefore by definition considered to be a singular event in G1. Autonomy from …

Gauge/ Gravity Correspondence, Bulk Locality And Quantum Black Holes, Debajyoti Sarkar

Dissertations, Theses, and Capstone Projects

The aim of this dissertation is threefold. We begin by the study of two parallel ideal cosmic strings in the presence of non-minimal scalar fields and spin- 1 gauge fields. We show that the contributions of the non-minimal term on the interaction energy between the strings are similar to that of the gauge field for a particular value of non-minimal coupling parameter. In this context we clarify some of the issues that arise when comparing the renormalization of black hole entropy and entanglement entropy using the replica trick.

In the second part of the dissertation we study the process of …

Neuroimmune Crosstalk: A Role For Neuropeptide Y In Inflammatory Bowel Disease, Henry H. Ruiz

Dissertations, Theses, and Capstone Projects

Neuropeptide Y (NPY) is a 36-amino acid peptide widely expressed in the central and peripheral nervous systems. In addition to other cells, NPY is also synthesized and co-released from sympathetic nerve fibers functioning as a potent sympathetic neuromodulator. NPY has been implicated in playing important roles in the regulation of energy balance, appetite, anxiety, vascular tone, and immune cell functioning. In addition, immune cells of both the innate and adaptive immune systems express functional NPY receptors. Some immune cells can produce and secrete NPY, and genetic alteration of these receptors results in altered immune cell functioning. Its direct association with …

Measuring The Transmission Matrix For Microwave Radiation Propagating Through Random Waveguides: Fundamentals And Applications, Zhou Shi

Dissertations, Theses, and Capstone Projects

This thesis describes the measurement and analysis of the transmission matrix (TM) for microwave radiation propagating through multichannel random waveguides in the crossover to Anderson localization. Eigenvalues of the transmission matrix and the associated eigenchannels are obtained via a singular value decomposition of the TM. The sum of the transmission eigenvalues yields the transmittance T, which is the classical analog of the dimensionless conductance g. The dimensionless conductance g is the electronic conductance in units of the quantum conductance, G/(e^2/h).

For diffusive waves g>1, approximately g transmission eigenchannels contribute appreciably to the transmittance T. In …

Reviving Enlightenment In The Age Of Nationalism: The Historical And Political Thought Of Hans Kohn In America, Brian Matthew Smollett

Dissertations, Theses, and Capstone Projects

This dissertation critically engages the thought of Hans Kohn (1891-1971). One of the most prominent theorists of nationalism in the twentieth century, Kohn has primarily been studied as an anti-statist Zionist thinker and as the originator of a Western-Civic/Eastern-Ethnic "dichotomy" of national development. This work takes a different approach by analyzing the matrix of tension between particularism and universalism in his mature, American thought. I argue that Kohn, especially in response to the crisis of fascism, used history to search for a balance within this perennial tension. His historical analyses, very much tied to his time and context, led him …

We Work, We Eat Together: Anti-Authoritarian Mutual Aid Politics In New York City, 2004-2013, David Spataro

Dissertations, Theses, and Capstone Projects

New York City's neoliberal restructuring has fundamentally transformed the city's labor market and privatized many important aspects of a once robust municipal welfare system. In this research I examine one radical response to these changes: anti-authoritarian mutual aid groups that blend Do-It-Yourself (DIY) culture with direct action politics. These are projects where activists attempt to build strong communities of resistance by organizing collective forms of social reproduction. I find that these projects are a threat to neoliberal urbanization because they reorganize reproduction beyond the household scale while simultaneously criticizing the social relations of capitalism as the root of household insecurity. …

Adolescents' And Young Adults' Moral Thinking In Typical Everyday-Life Moral Dilemmas, Yoko Takagi

Dissertations, Theses, and Capstone Projects

This research examined adolescents' and young adults' practical moral judgments, specifically their unique moral thinking in two interpersonal moral dilemmas. The basic philosophical frameworks (deontological and consequentialist principles) were employed as tools for psychological analysis. In Study 1, 42 preliminary groups of adolescents and young adults (14-16 years and 18-21 years) provided moral dilemmas that they had experienced during a past year. Among 42 dilemmas, two dilemmas (the homework and the video dilemmas), including different types of conflicting moral issues, were selected as materials for Study 2. In Study 2, 234 participants (76 aged 14-16, 90 aged 18-19, and 68 …

Common Knowledge: The Epistemology Of American Realism, Mark Sussman

Dissertations, Theses, and Capstone Projects

My dissertation, Common Knowledge: The Epistemology of American Realism, focuses on realist fiction (primarily the novel) at the end of the nineteenth century. Its motivating claim is that the central descriptive and thematic imperative of realism--to depict life "as it is" rather than in some idealized form--emerged in response to crises in the status of knowledge that resulted from an attempt by writers and readers to come to a common understanding of the relationship between private experience and an increasingly fragmented social world. While William Dean Howells's definition of realism as a form of writing that displays "fidelity to experience …

Xenakis In America, Charles Wolcott Turner

Dissertations, Theses, and Capstone Projects

Iannis Xenakis had a long-standing interest in the U.S., but given the five years he spent here, little has been written about his experiences. This study attempts, through archival research and interviews, to document Xenakis’ time in the United States. Its subject is his relationship to American cultural institutions, and in what lured Xenakis here for musical composition and research.

The narrative treats the period from Copland’s invitation to Tanglewood in 1963, through Xenakis’ 1972 investment by France as a state-supported artist. While he visited the U.S. many times thereafter, he no longer sought long-term engagement with U.S. institutions, but …

Exploring The Role Of Perceived Religiosity On Daily Life, Coping, And Parenting For Jewish Parents Of Children With Autism, Frances Rebecca Victory

Dissertations, Theses, and Capstone Projects

This two-part study (a) explores the multi-dimensional aspects of religious and psychosocial experience of Jewish mothers and fathers with and without a child with autism; and (b) uses a multi-method design to examine the influence of perceived religious beliefs, ritual practices, and community context on daily life, parenting, and coping processes for these parents. The first study included 20 fathers and 34 mothers of typically developing children. Participants were affiliated with Reform, Conservative, and Modern Orthodox Judaism. They completed three online q-sorts and five open-ended questions. The three q-sorts focused on the perceptions of religious beliefs, ritual practices, and community …

The Effect Of Malintent On Visual Attention, David Brian Wallace

Dissertations, Theses, and Capstone Projects

Malintent is a relatively unexplored phenomenon, despite the practical and theoretical interest in its detection. The four studies presented here, informed by the Guilty Knowledge Test and Guided Search model of visual attention, illustrate how eye tracking can (and cannot) be utilized to detect malicious intent. Malintent, induced in two different mock crime paradigms (murder; theft), boosted the frequency and duration of fixations that fell upon objects relevant to their task. The size of the malintent effect ranged from moderate (fixation duration) to large (fixation frequency). The increased visual attention given to task-relevant objects was not unique to malintent; benign …

An Experimental Investigation Into The Mechanisms Of Bacterial Evolution, Zhenmao Wan

Dissertations, Theses, and Capstone Projects

This thesis studies the two fundamental mechanisms of bacterial evolution — horizontal gene transfer and spontaneous mutation, in the bacterium Escherichia coli through novel experimental assays and mathematical simulations. First, I will develop a growth assay utilizing the quantitative polymerase chain reaction (qPCR) to provide real-time enumeration of genetic marker abundance within bacterial populations. Second, I will focus on horizontal gene transfer in E. coli occurring through a process called conjugation. By fitting the qPCR data to a resource limited, logistic growth model, I will obtain estimated values of several key parameters governing the dynamics of DNA transfer through conjugation …
