Pittsburgh's Response To Deindustrialization: Renaissance, Renewal And Recovery, 1946-1999, Mariel P. Isaacson

Dissertations, Theses, and Capstone Projects

Pittsburgh was able to gradually ease its transition into a post-industrial economy in the second half of the twentieth century because of an elite-driven planning movement known as the Pittsburgh Renaissance. The Renaissance first addressed the physical failings of the city and sought state legislation that would support further urban redevelopment immediately following World War II. While the physical improvements were underway, Renaissance organizers began working with the University of Pittsburgh to upgrade Pitt's educational and recreational facilities so that it would become an engine for the city's future economic growth. City support for improved facilities, especially those pertaining to …

"We Are Refugees In Our Own Homeland": Land Dispossession And Resettlement Challenges In Post-Conflict Teso, Uganda, Matt Kandel

Dissertations, Theses, and Capstone Projects

This dissertation is based off of fieldwork that I conducted in post-conflict Teso region in northeastern Uganda from 2012-2013. It focuses primarily on land dispossession and challenges to resettlement. Conflicts over land intensified in the early 1990s, coinciding with the early stages of resettlement in southern Teso after a period of regional civil war and large-scale cattle rustling. In contrast to the large-scale "land grabs" in Sub-Saharan African that have occurred since the 2007-08 global commodities crisis, land expropriations occur mainly on a small-scale in Teso. I argue that there are a number of drivers to land dispossession in the …

An Equine-Facilitated Prison-Based Program: Human-Horse Relations And Effects On Inmate Emotions And Behaviors, Keren Bachi

Dissertations, Theses, and Capstone Projects

Policy makers and correctional authorities are seeking ways to enhance effectiveness of incarceration and reduce recidivism. Equine-facilitated prison-based vocational programs aim to rehabilitate inmates. Informed by the theories of attachment and desistance, this study evaluates the emotional and behavioral effects of such an intervention utilizing a quasi-experimental methodological triangulation design.

Recidivism and disciplinary misconduct are examined by clinical data-mining of institutional records. Propensity Score Matching, binary and multinomial logistic regressions are applied in a discrete-time event history analysis. Semi-structured interviews revealing the subjective experiences of participants are analyzed via the Listening Guide methodology. Quantitative questionnaires, exploring attachment and closeness to …

Studies In Volatility, Nazli Sila Alan

Dissertations, Theses, and Capstone Projects

This dissertation consists of five chapters that focus on the price discovery role of equity markets and examine the evolution of intraday stock price volatility as a key measure of market quality. Using six differentiated measures of intraday volatility (that mostly focus on the opening half-hour of trading), all common stocks listed at three stock exchanges with varying levels of fragmentation are analyzed: NYSE and NASDAQ stocks over the period 1993-2012, and Istanbul Stock Exchange (ISE) stocks over the period 2000-2011.

The results on the evolution of intraday volatility presented in Chapters 2 and 3 indicate the following: In 1993, …

Examining The Association Of Medication Complexity With Health-Related Quality Of Life In Older Adults Receiving Community-Based Long Term Services And Supports, Claudia Ann Beck

Dissertations, Theses, and Capstone Projects

While the complexity of a medication regimen is a concern for all individuals, it is of significant concern for community-dwelling older adults who often require multiple medications to treat chronic health problems. Health related quality of life (HRQoL) has been identified as a key quality outcome measure when assessing care of older adults, particularly those with long-term care needs. Although the use of multiple medications has been widely explored in the literature, there is a paucity of data regarding the combination of several medication-related factors (number of active medications, therapeutic drug class, and medication regimen complexity) and HRQoL in older …

Women In Foreclosure: Social Reproduction & Mortgage Strain In The Subprime Era, Amy Baker

Dissertations, Theses, and Capstone Projects

Advisor: Professor Mimi Abramovitz

This research captures the experiences of 31 single female homeowners with risky lending markets and mortgage foreclosure in the city of Philadelphia. In-depth, semi-structured interviewing was employed to build knowledge about single women's experiences with seeking a loan, buying a home, entering default and attempting to stall foreclosure. Thematic analysis of the data demonstrated that risky lending and foreclosure did not mark the onset of financial instability among study participants. Instead, it functioned as a tipping point for single women unable to access upward mobility and asset accrual throughout the lifespan. Women's status as the strongest …

Cologne Carnival's "Alternative" Stunksitzung: Carnivalization? Meta-Carnival? Or Bakhtinian Restoration?, Erik Abbott

Dissertations, Theses, and Capstone Projects

In the 1820s, Carnival in Cologne, Germany, underwent a series of reforms, ostensibly to bring the festival back to the people. Among the traditions that developed was the Sitzung, a theatrical variety-show event, with music, comic speeches and sketches, dance troupes, and various additional Carnival-related entertainments. The shows, and Carnival itself were, and largely have been since that time, mostly overseen by a Festival Committee and the official Carnival Societies it recognizes.

In 1984, a group of mostly students decided to create their own version of a Sitzung, an alternative version, the Stunksitzung. From three inaugural performances, it has grown …

The Influence Of Pseudo-Relatives On Attachment Preferences In Spanish, David Branco-Moreno

Dissertations, Theses, and Capstone Projects

This paper presents the results from an off-line experiment on the extent to which the availability of pseudo-relatives modulates attachment preferences in Spanish. Participants were presented with sentences in which different syntactic and semantic factors had been manipulated to allow for either both a pseudo-relative (PR) and a relative-clause (RC) reading or a RC reading only. All the experimental items included two potential antecedents with which the constituents of interest could be associated. The experimental items can be divided into four groups: group 1 consists of stimuli allowing for a double reading in direct object position, and groups 2, 3 …

Bureaupathology And Organizational Fraud Prevention: Case Studies Of Fraud Hotlines, Chelsea Ann Binns

Dissertations, Theses, and Capstone Projects

This dissertation examined the effect of organizational bureaucracy on fraud hotline performance. Fraud hotlines are used to receive anonymous fraud tips from employees in all sectors to prevent and detect fraud. This work contributes to the research on fraud hotlines, which today is very light. This work also examined individual hotline performance against organization theory, which is absent in the literature. The literature also doesn't include studies using social media data to determine organizational climate. This work contributes to that literature by providing a collective case study examination of the fraud hotlines in six organizations. Their hotline performance was examined …

Dynamics And Manipulation Of Nanomagnets, Liufei Cai

Dissertations, Theses, and Capstone Projects

This thesis presents my work on the spin dynamics of nanomagnets and investigates the possibility of manipulating nanomagnets by various means. Most of the work has been published\cite{LC-PRB2010, LC-PRB2012, LC-PRB2013, LC-EPL2014}. Some has been submitted for publication\cite{LC-arxiv2014}. The structure of this thesis is as follows.

In Chapter 1, I present the theory of manipulation of a nanomagnet by rotating ac fields whose frequency is time dependent. Theory has been developed that maps the problem onto Landau-Zener problem. For the linear frequency sweep the switching phase diagrams are obtained on the amplitude of the ac field and the frequency sweep rate. …

A Parent At War And The "Invisible Wounds" They Carry Home: Ptsd In Military Veterans And A Review Of Psychosocial Family System Challenges, Melina Sofia Calle

Dissertations, Theses, and Capstone Projects

Operation Enduring Freedom and Operation Iraqi Freedom have created a new generation of military veterans and military families, many of which must manage and cope with psychosocial challenges such as posttraumatic stress, depression, anxiety, and alcohol abuse induced by the psychological trauma(s) faced during war. Risk factors, buffering factors, and war zone stressors influencing the development of PTSD following military-related trauma will be reviewed. As many of these affected veterans return to living with spouses and children, these psychosocial issues show to bring forth tension, stress, and friction to the family system. This thesis explores the literature of family system …

The Vastness Of Small Spaces: Self-Portraits Of The Artist As A Child Enclosed, Matthew John Burgess

Dissertations, Theses, and Capstone Projects

A tent of bed sheets, a furniture fort, a corner of the closet surrounded by chosen objects--the child finds or fashions these spaces and within them daydreaming begins. What do small spaces signify for the child, and why do scenes of enclosure emerge in autobiographical self-portraits of the artist? Sigmund Freud's theory that the literary vocation can be traced to childhood experiences is at the heart of this project, especially his observation that "the child at play behaves like a writer, in that he creates a world of his own, or rather, re-arranges the things of this world in a …

Temporal Information Extraction And Knowledge Base Population, Taylor Cassidy

Dissertations, Theses, and Capstone Projects

Temporal Information Extraction (TIE) from text plays an important role in many Natural Language Processing and Database applications. Many features of the world are time-dependent, and rich temporal knowledge is required for a more complete and precise understanding of the world. In this thesis we address aspects of two core tasks in TIE. First, we provide a new corpus of labeled temporal relations between events and temporal expressions, dense enough to facilitate a change in research directions from relation classification to identification, and present a system designed to address corresponding new challenges. Second, we implement a novel approach for the …

The Role Of Water In The Rise, Prominence, And Decline Of Nabataean Petra, Dennis Cummins

Dissertations, Theses, and Capstone Projects

This paper evaluates the rise of Nabataean Petra, its prominence, and eventual decline. The predominant context is effective water management as a pivotal driving factor in the growth of the Nabataean kingdom, which fostered an environment in which its famous incense trade could develop. Rising incense demand was the catalyst for growth from the first century BC through the first century AD; in AD 106 when Rome annexed the Nabataean kingdom, Petra began its gradual decline. In AD 363 an earthquake destroyed much of the city, and Petra did not return to its earlier prominence. From the outset, water played …

Structure And Function In Bacteriophage Phi6, James Carpino

Dissertations, Theses, and Capstone Projects

The present study of bacteriophage Phi6 has been preceded by a great number of exploratory studies of its structure and function, and these studies have formed a basis for Phi6's development into a model organism. In this study, two aspects of the model organism have been examined. 1. There are several uncharacterized and presumed untranslated regions (UTRs) in Phi6's 13.3 kilobase-pair dsRNA genome. I examined the impact of specific modification to the 3' UTR of the small segment of bacteriophage Phi6. I determined that modification to the purported UTR of the small segment resulted in severe fitness costs, supporting a …

Yang-Mills Theories As Deformations Of Massive Integrable Models, Axel Cortes Cubero

Dissertations, Theses, and Capstone Projects

Yang Mills theory in 2+1 dimensions can be expressed as an array of coupled (1+1)-dimensional principal chiral sigma models. The SU(N) principal chiral sigma model in 1+1 dimensions is integrable, asymptotically free and has massive excitations. We calculate all the form factors and two- point correlation functions of the Noether current and energy-momentum tensor, in

't Hooft's large-N limit (some form factors can be found even at finite N). We use these new form factors to calculate physical quantities in (2+1)-dimensional Yang-Mills theory, generalizing previous SU(2) by P. Orland to SU(N). The anisotropic gauge theory is related to standard isotropic …

(Remember) The Future: The Preemptive Governance Of Memory In The Age Of Mass Catastrophe, Kimberly J. Cunningham

Dissertations, Theses, and Capstone Projects

This study is a critical engagement with the preemptive turn in post-biopolitical governance in psychotherapies to treat traumatic memory and its related clinical diagnosis, post traumatic stress disorder (PTSD), in the wake of the mass disasters of the 21st century. Emerging in the post-911 era of increased anticipatory action in the governance of populations and also, increasingly ubiquitous and large scale threat such as global recession, climate change, and terrorism/war, traumatic memory of these events is framed increasingly as a population-level contagion to be addressed by anticipatory action. A study of trends in emerging and favored psychotherapies for trauma post-911 …

Recruitment Of The Ribosomal 40s Subunit To The 3'Untranslated Region Of A Viral Mrna, Via The Eif4 Complex, Facilitates Cap-Independent Translation, Sohani Das Sharma

Dissertations, Theses, and Capstone Projects

Translation of uncapped plant viral RNAs can be facilitated by either an internal ribosomal entry site (IRES) in the 5' untranslated region (UTR) or a cap-independent translation element (CITE) in the 3' UTR. Barley yellow dwarf virus (BYDV) mRNA, which lacks both cap and poly(A) tail, has a translation element (3'BTE) in its 3' UTR that is essential for efficient translation initiation at the 5'-proximal AUG. This mechanism requires binding of the eukaryotic initiation factor 4G (eIF4G) subunit of the heterodimer eIF4F to the 3'BTE and base pairing between the 3'BTE and the 5' UTR. Here we investigate how this …

The Sound Patterns Of Camuno: Description And Explanation In Evolutionary Phonology, Michela Cresci

Dissertations, Theses, and Capstone Projects

This dissertation presents a linguistic study of the sound patterns of Camuno framed within Evolutionary Phonology (Blevins, 2004, 2006, to appear). Camuno is a variety of Eastern Lombard, a Romance language of northern Italy, spoken in Valcamonica. Camuno is not a local variety of Italian, but a sister of Italian, a local divergent development of the Latin originally spoken in Italy (Maiden & Perry, 1997, p. 2). It is an oral language with no writing system, and it is endangered. The language is understudied (Bonfadini, 1995, p. 26), and this thesis appears to be the first detailed study of Camuno …

Comparative Phylogeography, Phylogenetics, And Population Genomics Of East African Montane Small Mammals, Terrence Constant Demos

Dissertations, Theses, and Capstone Projects

The Eastern Afromontane region of Africa is characterized by striking levels of endemism and species richness which rank it as a global biodiversity hotspot for diverse plants and animals including mammals, but has been poorly sampled and little studied to date. Using mtDNA and multi-locus nDNA sequence data, genome-wide RAD-Seq SNP data, and morphological data, I identify major cryptic biogeographic patterns within and between 11 co-distributed small mammal species/species groups across the Eastern Afromontane region. I focus on two endemic montane small mammal species complexes, Hylomyscus mice and Sylvisorex shrews, co-distributed across the Albertine Rift (AR) and Kenya Highlands (KH) …

Multimodal Emotion Perception In Borderline Personality Disorder, Virginia Fineran

Dissertations, Theses, and Capstone Projects

Borderline personality disorder (BPD) is a chronic disorder characterized by pervasive difficulties in the emotion regulation system. While it is clear that individuals with BPD frequently exhibit intense emotional reactions, lack abilities to effectively manage such emotions, and often engage in serious maladaptive behaviors as a consequence of intense emotions, many aspects of the process by which this sequence occurs are not well understood. One crucial aspect of emotion regulation is the processing and perception of cues from the environment. To date, processing of emotional cues in individuals with BPD has been understudied. Therefore, the purpose of this paper is …

Enhancing Self-Monitoring And Self-Reflection Through A Self-Regulatory Skills Intervention Embedded In A Middle School Mathematics Curriculum, Gregory Digiacomo

Dissertations, Theses, and Capstone Projects

The purpose of this study was to investigate the effects of a self-regulatory strategy intervention designed to improve participants' calibration accuracy, self-regulatory skills, and math achievement. Monitoring and self-reflection processes were the main focus of this intervention as they are key processes in many well-validated models of self-regulated learning and have been found to impact academic achievement and overall self-regulatory skill (Bol et al., 2010; Dunlosky & Rawson, 2011; Hacker et al., 2008; Nietfeld et al., 2005). The participants were 30 sixth and seventh grade students who were learning about probability as part of their normal math curriculum during the …

Does End Of Life Terminology Influence Decisional Conflict In Surrogate Decision Makers?, Dawn Fairlie

Dissertations, Theses, and Capstone Projects

This study investigated the relationship between end of life terminologies and decisional conflict in surrogate decision makers using a convenience sample of 234 adults age 50 and older at active adult communities, and senior centers in New Jersey. Participants were randomized into two groups, and each received a vignette that was personalized. The vignettes varied only in the use of the words "Do Not Resuscitate (DNR)" and "Allow Natural Death (AND)". The Decisional Conflict Scale (DCS) was administered.

There was no difference in total DCS score based on AND and DNR versions. However, AND respondents perceived their decision as a …

Role Of The Polyadenylation Factor Cstf-50 In Regulating The Brca1/Bard1 E3 Ubiquitin (Ub) Ligase Activity, Danae Fonseca

Dissertations, Theses, and Capstone Projects

The cellular response to DNA damage is an intricate mechanism that involves the interplay among several pathways. The studies presented in this dissertation focus on the determination and characterization of the role of mRNA processing factor CstF-50 and escort protein p97 in the regulation of the BRCA1/BARD1 E3 ubiquitin (Ub) ligase activity during the DNA damage response (DDR).

As part of the studies presented in Chapter II, I determined that the polyadenylation factor CstF plays a direct role in DDR, specifically in transcription-coupled repair (TCR), and that it localizes with RNA polymerase II (RNAP II) and BARD1 to sites of …

Huu-Fa Thesis Dat?: A Syntactic Analysis Of Possessive Jamaican Creole Possessive Wh-Elements, Toni Ashlie Foster

Dissertations, Theses, and Capstone Projects

This thesis discusses the differences between the Jamaican Creole expressions huu-fa and fi-huu. Jamaican Creole is a language that was born from a combination of the lexifier language English and the substrate language Twi, therefore it is reasonable to check whether the features of JC were derived from these languages. The distribution of huu-fa and fi-huu resembles the distribution of English whose. Fi-huu and huu-fa are WH-elements that show possession, similar to the English word whose. They are made of a WH-pronoun and a form of the preposition fi "for". Both terms differ in internal structure, and distribution. The difference …

Saudi Aramco And The Politics Of Cultural Heritage, Anahid Hanounik Huth

Dissertations, Theses, and Capstone Projects

Culture Heritage in recent decades has become a catch word within world discourse. It is increasingly receiving generous attention in both money and time form private and public sectors on preservation policy. The application of so-called preservation and restoration projects, the alleged care for Cultural Heritage, has become a motive and battle cry of UNESCO, World Bank, private companies, banks, NGOs, European Council, and Western governments' foreign policy. This leads us to ask what is behind this increasing attention, and whether we should see it as Christina Luke 2013 suggested in her article--is Heritage increasingly being seen as a soft …

The Knowing Body: Participatory Artistic-Embodied Methodologies For Re-Imagining Adolescence, Madeline Fox

Dissertations, Theses, and Capstone Projects

Braiding critical youth studies, social science methodologies, participatory action research, performance studies, and art, this dissertation investigates how we can produce knowledge collectively toward reimagining adolescence. Polling for Justice was a multi-generational participatory action research project that took place between 2008 and 2011. Polling for Justice was interested in understanding young people's lived experiences at the intersections of education, criminal justice, and public health in New York City. The study centered on a city-wide survey and a series of data-driven focus groups. The Polling for Justice research collective used participatory artistic-embodied methodologies to make sense of, and later perform, the …

Homeostasis-Driven Responses To Consumer Sensations, Rhonda Hadi

Dissertations, Theses, and Capstone Projects

This research examines the effect of experienced physical temperature on an individual's decision-making process. Reliance on emotions can function as a warming process and reliance on cognitions can function as a cooling process, hence individuals are nonconsciously induced to alter their decision-making style according to their thermoregulatory objectives. My first two studies support a thermoregulatory account by demonstrating that the mere use of cognitive versus affective processing leads to both self-reported and objective changes in body temperature, and that the adoption of a compensatory pathway can indeed aid in providing temperature-related comfort. My last three studies demonstrate that individuals adopt …

Internalizing Disorders In Early Childhood: Professional Development Framework For Teachers, Danielle Guttman

Dissertations, Theses, and Capstone Projects

Recent research indicates that internalizing disorders such as depression, anxiety, and posttraumatic stress disorder (PTSD) manifest in young children. Since early childhood teachers spend a substantial portion of their day with young children, it is important to examine their beliefs and behaviors surrounding these disorders. The role of the school psychologist has come to include providing support for educators such as presenting up-to-date research through professional development (PD). The current investigation implemented an intervention designed to compare different forms of PD seminars ("Information" and "Strategies") designed to increase teachers' awareness of internalizing disorders in early childhood. Ninety-nine participants comprised the …

Place Connections: A Study Of The Dynamics And Planning Process Of Remigration In Trinidadians And Tobagonians, Lystra Huggins

Dissertations, Theses, and Capstone Projects

The purpose of this dissertation is to study migration and remigration of Trinidadians and Tobagonians as it relates to the meaning, experiences, and attachment these individuals have with the different places they have lived. The research questions focus specifically on remigrants who have the choice to return to Trinidad and Tobago or not after long-term residence abroad and why they make the decision to return. Interviews and surveys were used to understand the roles of place identity, place attachment, and place dependence in choosing whether or not to remigrate to Trinidad and Tobago. Participants were asked about their understanding of …
