Crater Detection Via Genetic Search Methods To Reduce Image Features, Joseph Paul Cohen

Graduate Masters Theses

Recent approaches to crater detection have been inspired by face detection's use of gray-scale texture features. Using gray-scale texture features for supervised machine learning crater detection algorithms provides better classification of craters in planetary images than previous methods. When using Haar features it is typical to generate thousands of numerical values from each candidate crater image. This magnitude of image features to extract and consider can spell disaster when the application is an entire planetary surface. One solution is to reduce the number of features extracted and considered in order to increase accuracy as well as speed. Feature subset selection …

Racism And Anxiety In A Black American Sample: The Role Of Mediators And A Brief Mindfulness Manipulation, Jessica Rose Graham

Graduate Doctoral Dissertations

It is important to determine factors that may exacerbate the negative effects of experiences of racism on anxiety, as well as factors that might buffer racism's negative impact on anxiety in Black American samples. To examine these factors, we conducted two related studies. In study 1, 119 Black American individuals completed the Schedule of Racist Events, the five factor mindfulness questionnaire, the anxiety control questionnaire (assessing perceptions of control), the self-hatred subscale of the cross racial identity scale, and the depression anxiety and stress Scale. As hypothesized, frequency of racist experiences over the past week was significantly positively associated with …

Producing Space: Block-By-Block Change In A Gentrifying Neighborhood, Jen Douglas

Graduate Doctoral Dissertations

Gentrification of urban neighborhoods is part of an ongoing restructuring of the city, linked to the emerging occupational structure of the service economy and the remaking of built environments that were created for a production economy. It is the name given to processes in which commodification and reinvestment accompany the in-migration of professional and managerial workers, often displacing prior residents and giving altered spatial form to inequality.

This dissertation is a case study of gentrification in Hyde and Jackson Squares, part of Boston's Jamaica Plain neighborhood. The emergence of gentrification pressures and their uneven distribution within the area is documented …

The Association Between Elementary Teacher Licensure Test Scores And Student Growth In Mathematics: An Analysis Of Massachusetts Mtel And Mcas Tests, Life Legeros

Graduate Doctoral Dissertations

This quasi-experimental value-added study provided evidence for the predictive validity of the Massachusetts MTEL General Curriculum Mathematics Subtest by finding an association between the licensure test results of 130 teachers and the growth of their 2640 grade 4 and 5 students. The study took advantage of a natural experiment that arose due to a policy change made by the Massachusetts Department of Elementary and Secondary Education (MADESE) in response to the initial administration of a new highly rigorous math-specific licensure subtest for elementary and special education teachers in March, 2008. The emergency amendment allowed test takers to conditionally pass the …

Reconceptualizing Cultural Competence: White Placeling De-/Reterritorialization Within Teacher Education, Melissa Winchell

Graduate Doctoral Dissertations

This ethnography reconceptualizes the paradigm of cultural competence used within the literature on teacher education to describe the multicultural learning of White teacher candidates. Within the cultural competence framework, White learning is problematic, dichotomously defined, and fixed. The binary of competence/incompetence established by this paradigm has recently been questioned within the literature as deficit-based and in conflict with postmodern, critical theories of learning and teaching espoused by multicultural education espouses. This study of the researcher's multicultural education class at a private, religious, four-year undergraduate college on the East Coast of the United States used co-constructed pedagogical practices--including a co-constructed community …

Germs, Pigs And Silver: King Philip's War And The Deconstruction Of The Middle Ground In New England, Benjamin M. Roine

Graduate Masters Theses

Early in the seventeenth century Algonquians peoples of southern New England and English colonists built a middle ground which benefitted both groups. Trade, the existence of competition from Dutch and French colonies and powerful Algonquian tribes maintained this middle ground. However, as trade items, such as beaver pelts and wampum became rare or lost value and continued English immigration to New England weakened Dutch claims to the area, the middle ground began to crumble. As English-style farms and livestock changed the ecology of New England and the colonists sought to assert their will, Algonquians lost the ability to live as …

The Effects Of Nesting Environment On Neonatal Hypoxic-Ischemic Injury, Laura Grace Rollins

Graduate Masters Theses

Term neonates with hypoxic-ischemic (HI) injury are at risk for devastating neurological sequelae. The objective of this study is to determine if altering the early environment for maternal care-taking impacts the immediate and long-term sequelae of HI offspring. The Rice-Vannucci model was used to induce HI in postnatal day (PND) 7 Long-Evans pups. Litters were assigned to a closed nest (CN) or normal standard housing (SH) condition. Neurobehavioral development, cognitive ability, and stress response were assessed to establish any benefits of the CN condition. Finally, postmortem brain tissue was analyzed for morphometric markers of injury.

Studying Soil Moisture And Land-To-Water Carbon Export In Urbanized Coastal Areas Using Remotely Sensed Data And A Regional Hydro-Ecological Model, Yun Yang

Graduate Doctoral Dissertations

The main objective of this research was to study the flux of dissolved organic carbon (DOC) from a terrestrial urbanized watershed to an estuarine system using a process-based regional hydro-ecological model and remotely sensed data.

While DOC is an important component of the global carbon cycle, the link of the variations in terrestrial carbon storage is still poorly understood. Soil moisture is a key factor that influences the amount of available water for vegetation growth and the decomposition rate of organic matter in the soil and thus contributes to the amount of DOC in the soil at the land-water boundary. …

Microfinance: A Tool For Financial Access, Poverty Alleviation Or Gender Empowerment ? - Empirical Findings From Pakistan, Ghazal Mir Zulfiqar

Graduate Doctoral Dissertations

In just 30 years microfinance has transformed from a credit-based rural development scheme that has claimed to reduce poverty and empower poor women, to a $70 billion financial industry. In the process, the traditional NGO-led model has given way to commercialized institutions, resulting in an increased emphasis on profitmaking. This has also led to confusion in the sector around its mission: is it to alleviate poverty and empower poor women or simply to provide the "unbanked" with access to formal sources of finance? This research considers the main debates in microfinance with regard to its mission and presents empirical evidence …

Maternal Self-Efficacy And Perceived Stigma Among Mothers Of Children With Asd, Adhd, And Typically Developing Children, Sara D. Rosenblum-Fishman

Graduate Doctoral Dissertations

Maternal self-efficacy (a mother's beliefs about her parenting competence) is an important area of mothers' wellbeing and overall family functioning. This study examined environmental factors that are related maternal self-efficacy among mothers of children with autism spectrum disorder (ASD group), mothers of children with Attention-Deficit/Hyperactivity Disorder (ADHD group), and mothers of typically developing children (Typical group). Environmental factors included (a) messages of criticism or blame about one's parenting competence (parenting-related perceived stigma), (b) child problem behaviors, (c) maternal stress, and (d) social support. One hundred eighty mothers of school-age children living in the United States completed the measures on-line. Results …

How Ending Gender Violence In India Improves The Nation's International Reputation And Tourism Industry: A Case For Nationalism, Sharon Nambudripad Schiffer

Graduate Masters Theses

As nations have become far more interconnected by means of globalization in the 21st century, the issues that affect one nation often have affects upon others. As India is a nation with a population of more than 1.2 billion, the issues that affect the nation also affect others. As an assault in Delhi, India made international news on December 16, 2012, the international community has become more aware of the incidents of gender-based violence that exist within the country. The ramifications of the international community's knowledge of the assault included a drastic decrease in both its international reputation and its …

The Syntax Of The Arabic Determiner Phrase, Mohamed Cheikh Beina

Master's Theses and Doctoral Dissertations

The goal of this thesis is to analyze the syntactic structure of the Arabic determiner phrase (DP) within the confines of Chomsky's minimalist program. Attention is drawn to a number of the misconceptions many linguists have about this constituent. Some of the issues that linguists overlook include the existence of an indefinite article as well as a possessive determiner that heads the genitive phrase. A new analysis of agreement within DP is presented, as well as an argument against the construct state analysis and analyses of other related issues.

Hip-Hop, Medellín And Social Change, Veronica Henao Posada

Master's Theses

This study explores the ways in which the Hip-hop movement is producing social change in Medellín, Colombia. Looking specifically at a Hip-hop school called Cuatro Elementos Skuela, which exists autonomously and with very little state support in the Medellín neighborhood of Aranjuez, I argue that young people are contributing to the reconstruction of the city’s social, cultural and economic fabric. I start by explaining the historical context of Medellín, describing the different sets of conflicts that unleashed high levels of violence and caused the fragmentation of the social, cultural and economic fabric. Moreover, I review the role of the …

Private Flashbulb Memories: The Case Of Coming Out Memories, Gabrielle Weber

Undergraduate Honors Thesis Collection

Participants (N = 83) from Butler University and communities in Indianapolis, IN answered a three part questionnaire regarding their experience revealing their homosexual identity to their parents that included: a narrative, a set of probe questions, and a short demographic section. The narrative and probed recall data were scored in a similar fashion to flashbulb memory narratives with canonical features. The memory of revealing homosexuality to parents displayed flashbulb-like qualities. We found that those most confident in their probed recall answers were those with moderate arousal and few recounts. Also, those reporting moderate affect and fewer recounts had better memory …

Techniques For The Visualization Of Positional Geospatial Uncertainty, Brent A. Barré

University of New Orleans Theses and Dissertations

Geospatial data almost always contains some amount of uncertainty due to inaccuracies in its acquisition and transformation. While the data is commonly visualized (e.g. on digital maps), there are unanswered needs for visualizing uncertainty along with it. Most research on effectively doing this addresses uncertainty in data values at geospatial positions, e.g. water depth, human population, or land-cover classification. Uncertainty in the data’s geospatial positions themselves (positional uncertainty) has not been previously focused on in this regard. In this thesis, techniques were created for visualizing positional uncertainty using World Vector Shoreline as an example dataset. The techniques consist of a …

The focus of this thesis was to develop vocabulary materials to supplement those already in use for emergent literate Burundian refugees preparing for the U.S. Citizenship Test. These learners study in conjunction with the International Rescue Committee in Salt Lake City, Utah, and with volunteer tutors who help them study. The flashcards and supporting activities were designed to better enable tutors to teach learners highly-dense vocabulary items, as well as to provide vocabulary scaffolding support for both learners and tutors and to increase depth of vocabulary knowledge with the target vocabulary. The U.S. Citizenship Test Vocabulary Flashcards and Vocabulary Support …

Effects Of A Cross-Age Peer Tutoring Program On Reading Performance Of Hispanic Title I Second And Third Grade Students, Ana Isabel Rodriguez

Theses and Dissertations

Hispanic students are falling behind their peers in reading fluency and are struggling to close the gap. This study examined the reading fluency influence on 73 Hispanic second and third grade students while receiving reading fluency support from middle school Hispanic tutors. These students were compared to Hispanic second and third grade students not receiving tutoring reading support. All students were assessed before the tutors gave reading support, mid-year and after the reading support finished using a school district fluency measurement. Findings found that students made rapid growth in reading fluency from the beginning of the tutoring support to mid-year. …

The Association Between Hostile Attribution Bias, Social Intelligence, And Relational Aggression In Detained Boys, Gregory M. Fassnacht

University of New Orleans Theses and Dissertations

Research on factors that contribute to the forms and functions of aggression (reactive, proactive, relational, and overt) is important for informing intervention efforts with aggressive youth. Previous research shows that aggressive youth often have cognitive and social deficits associated with their aggressive behavior. For example, aggressive youth may exhibit deficits in social variables such as social intelligence (i.e., the understanding of behaviors of people and ability to predict outcomes of situations). Hypothetically, this lack of social intelligence may be related to how youth interpret social situations, and could conceivably lead to hostile attributional bias, or the tendency to interpret ambiguous …

Six Sigma, Firm Performance And Returns Predictability In Emerging Real Estate Market, Bora Ozkan

This dissertation consists of two essays. First essay investigates Fortune 500 companies that implemented Six Sigma. Since the 1980s, industrial organizations have adopted practices such as Six Sigma to maintain and enhance competitiveness. The purpose of this study is to look at the long run stock price and the operating performance of Fortune 500 companies that were identified to have implemented Six Sigma compared to the overall market performance as well as the performance of industry and size matched firms. Even though our sample firms improved several variables after implementing Six Sigma, their operating performances were not quite close to …

Big Five Personality Traits, Pathological Personality Traits, And Psychological Dysregulation: Predicting Aggression And Antisocial Behaviors In Detained Adolescents, Katherine S. L. Lau

University of New Orleans Theses and Dissertations

This study tested the utility of three different models of personality, namely the social and personality model, the pathological personality traits model, and the psychological dysregulation model, in predicting overt aggression, relational aggression, and delinquency in a sample of detained boys (ages 12 to 18; M age = 15.31; SD = 1.16). Results indicated that the three personality approaches demonstrated different unique associations with aggression and delinquency. The psychological dysregulation approach, composed of behavioral dysregulation, emotional dysregulation, and cognitive dysregulation, emerged as the overall best predictor of overt aggression, relational aggression, and delinquency. After controlling for the Big Five personality …

The Impact Of The Affordable Care Act On The Safety-Net. A Focus On Two Community-Based Clinics Serving Latin@ Immigrants In The Greater New Orleans Region, Rosa Herrin

University of New Orleans Theses and Dissertations

.

Latin@ immigrants face many obstacles to affordable healthcare that push them to disproportionately rely on the primary safety-net for their healthcare needs. This system is mostly funded with public monies that will be significantly reduced when Affordable Care Act is fully implemented. Since undocumented Latin@ immigrants are prohibited from accessing federally funded healthcare, they will be left out of the health care reform. This thesis examines two community-based clinics in the Greater New Orleans area that serve this population, and have developed linguistically and culturally appropriate programs that address its needs. The New Orleans Faith Health Alliance and Common-Ground …

Anxiety Sensitivity And Its Association With Parenting Behaviors, Rebecca Graham

University of New Orleans Theses and Dissertations

The aim of this study was to examine the association between parent and child anxiety sensitivity in the context of parenting behaviors, specifically by testing parenting behaviors as moderators or mediators of the association between parent and child anxiety sensitivity. Past research implies that parent anxiety sensitivity may be more related to child anxiety sensitivity (moderation) in girls and in the context of certain parenting. Alternatively, parenting behaviors may better account for the association (mediate) between parent and child anxiety sensitivity. To test the hypotheses 191 families (n = 255 youth aged 6-17 and their parents) completed measures of …

Hurricane-Exposed Youth And Psychological Distress: An Examination Of The Role Of Social Support, Donice M. Banks

University of New Orleans Theses and Dissertations

Hurricane exposure places youth at risk for psychological distress such as symptoms of Posttraumatic Stress Disorder (PTSD), anxiety, and depression, while social support may contribute to resilience following disasters. This study examined associations among family and peer social support, level of hurricane exposure, and psychological distress using both a large single-time assessment sample (N = 1098) and a longitudinal sample followed over a six-month period (n = 192). Higher levels of hurricane exposure were related to lower levels of social support from family and peers as well as to higher levels of psychological distress. Higher levels of family …

A Multi-Gene By Environment Perspective Of Adhd Symptomatology In Young Children, Amber L. Allison

University of New Orleans Theses and Dissertations

Attention deficit hyperactivity disorder (ADHD) is a heritable disorder, which has detrimental effects on childhood development and is associated with maladaptive functioning in adulthood. Despite this, we are far from an understanding of the etiology and possible trajectories of ADHD, possibly due to investigations focusing on the contribution of single genes. In fact, single genes are likely not influential enough to alter behavior, but the additive effect of many genes may predispose an individual toward certain behaviors. Further, environmental input can activate or suppress genetic expression, thereby leading to vast individual differences in both normative behavior and psychopathological illness, including …

Coupling Of The Hpa And Hpg Axes, Andrew Dismukes

University of New Orleans Theses and Dissertations

The Hypothalamic-Pituitary-Adrenal (HPA) and –Gonadal (HPG) axes have been considered mutually inhibitory; however, emerging evidence supports the proposition that this might not necessarily be the case. This idea is termed “coupling,” in which the HPA-HPG axis are mutually activated or deactivated. Coupling is examined across three data sets with different time-courses of stress exposure, and results demonstrate HPA-HPG co-activation occurs. Furthermore, stress exposure influences this relationship. The discussion shows how it is physiologically possible to have positive coupling or co-activation between these axes according to complex regulatory feedback systems and overlapping neural structures. Findings are interpreted developmentally, because adolescence may …

Assessing Risk In Adolescent Offenders: A Comparison Of Risk Profiles Versus Summed Risk Factors, Katherine A. Gottlieb

University of New Orleans Theses and Dissertations

Research supports interventions for high-risk juvenile offenders to reduce recidivism. Methods for assessing delinquent risk vary, however. Aggregate risk scores (i.e. number of risk factors) and specific risk profiles (i.e. types of risk factors) are both empirically supported techniques. This study compared aggregate scores versus profiles for predicting measures of criminal severity among detained adolescents (n=292). Twenty-four risk factors from the Structured Assessment of Violence Risk in Youth (SAVRY) were summed to calculate aggregate scores. Using latent class analysis (LCA), profiles were identified based on scores from the following theoretically important SAVRY risk factors: Risk Taking/Impulsivity, Anger Management …

Hostile Attributional Bias In Aggression And Anxiety: The Role Of Perceived Provocateur Motivation, Melissa M. Kunimatsu

University of New Orleans Theses and Dissertations

Although internalizing and externalizing problems are often considered in isolation from one another, the frequently co-occur in individuals leading to unique behavior profiles. The current study examined the associations between the forms, functions, and subtypes of aggression, anxiety, hostile attributional bias (HAB), and perceived (proactive or reactive) provocateur motivation in a sample of youth (mean age = 13.84 years, 51% male, 37.5% Caucasian). Results indicated that only reactive relational aggression significantly predicted anxiety, while relational and reactive aggression did not. HAB was not significantly associated with either anxiety or any type of aggression. Perceived proactive provocateur motivation was significantly associated …

The Streets Are Talking: The Aesthetics Of Gentrification In Two Downriver New Orleans Neighborhoods, Tara E. Foster

University of New Orleans Theses and Dissertations

Since the 1970s, when neoliberal policies and changing consumer patterns began remaking cities, scholars have conducted research about gentrification. In New Orleans, these studies have helped explain the demographic and economic shifts in some neighborhoods. However, there has been limited focus on the built environment aspects of gentrification in New Orleans, specifically the interpretation of the external aesthetic shifts in streetscapes as part of the gentrification process. This thesis examines the relationship between these aesthetics, primarily graffiti and street art, and the gentrification process, as perceived by various stakeholders in two New Orleans neighborhoods: St. Roch and Bywater. Using empirical, …

Sistas On The Move: An Ethnographic Case Study Of Health And Friendship In Urban Space Among Black Women In New Orleans, Valerie A. Mcmillan

University of New Orleans Theses and Dissertations

Abstract

Black women are disproportionately affected by adverse health conditions, such as obesity and heart disease. For example, more black women currently die from complications associated with diabetes, obesity and high blood pressure than any other ethnic group in the United States (Gourdine 2011). There are however, increasing numbers of everyday black women who defy these statistics and are positive role models for all women. One such group of women is the New Orleans chapter of Sistas On The Move (SOTM), an all-female running group that emphasizes the importance of black women’s health and builds community around physical activity. Through …

The Effects Of Chronic Simvastatin Treatment On The Expression Of Behavioral Symptoms In A Transgenic Mouse Model Of Huntington’S Disease, Ashley Whitmarsh

University of New Orleans Theses and Dissertations

Huntington’s disease (HD) is a heritable, neurodegenerative disorder characterized by motor, cognitive, and psychiatric disturbances. An unstable CAG expansion within the gene normally encoding for the Huntingtin protein is responsible. The expanded mutant form of Huntingtin and the putative protein co-factor Rhes interact and cause cell death within the striatum. We hypothesized chronic treatment with simvastatin, a cholesterol lowering drug, would disrupt the biosynthetical pathway which gives both Rhes and its target cells binding sites and render Rhes inactive. Healthy and HD mice were treated with simvastatin or a vehicle. Animals’ motor behavior was assessed with three separate tests over …
