Research suggests that adult attachment is associated with various social roles, such as parenting, with insecure attachment patterns corresponding to lower levels of parenting competence. An increasing amount of research suggests that attachment patterns and social roles are interwoven with gender role beliefs. With family systems theory as an overarching framework, the current study extends the literature by examining dyadic associations between these variables in a sample of 61 cohabitating couples with at least one child under of the age of 18 in the home. Participants included opposite-sex and same-sex romantic partners who were recruited using online snowball sampling processes. The actor-partner interdependence model was used to assess the mutual influences between romantic partners in the parental dyads, specifically focusing on attachment patterns, parenting competence, and the moderating effect of individual gender role-beliefs and incongruence between the two partners' gender role beliefs in the co-parenting relationship. Results indicated both actor and partner attachment anxiety and avoidance were negatively correlated with parenting competence; gender roles beliefs moderated that association with egalitarian gender role beliefs buffering the negative effects of partners' high attachment avoidance or anxiety. Additionally, results indicated that gender role belief incongruence between partners also moderated the relationship between attachment …

The current study employed both a variable- and person-centered approach to analyze data taken from a large sample of U.S. adults (N = 602, 59% males). For the former, structural equation modeling was utilized to empirically articulate the links between the four facets of psychopathy (interpersonal, affective, lifestyle, antisocial) and the six facets of ethnocentrism. For the person-centered approach, descriptive discriminant analysis was used to assess for differences in psychopathic trait profiles between those elevated or low in ethnocentric attitudes. Consistent with expectations, the affective dimension positively predicted denigration of out-group members whereas the lifestyle domain negatively predicted all facets of ethnocentrism. Unexpectedly, the antisocial facet positively predicted group cohesion and devotion towards one's ethnic in-group. Additionally, those elevated in ethnocentrism had higher interpersonal and affective scores and lower lifestyle scores relative to those low in ethnocentric attitudes. Results are discussed in the context of risk assessment for hate-based violence and the overlap in the nomological network of psychopathy and prejudicial attitudes.

This person-centered analytic approach identifies homogeneous offender subtypes in terms of psychopathic trait profiles and facilitates examination of correlates that may be linked with specific subtypes. Prosody is an external correlate that contains a wealth of information relevant to disruptions in cognition and affect and may offer novel insight into different psychopathic subtypes. The current study examined prosodic output in a male offender sample (n = 469) within the context of the clinical Psychopathy Checklist – Revised interview (PCL-R; Hare, 2003). Audio recorded speech samples were drawn from offender responses to affectively-charged PCL-R interview questions representing differing levels of valence and arousal. Generally consistent with previous literature, LPA results indicated that a four-class solution yielded the best model fit for the allocation of individual cases to subtypes with high overall classification accuracy (85%). Results of external validation analyses using mixed effects multivariate analysis of variance revealed significant two- and three-way interactions (psychopathy subtype x valence x arousal) for both speech production and variability indices that helped differentiate the subtypes. Overall, the current study suggests that meaningful differences exist in terms of prosodic output within psychopathic offender subtypes, which may be related to dysfunction in underlying affective processes. Implications of these …

Based on a step-wedge randomized control trial (intervention n = 136; comparison n = 137), this study investigated the impact of a peer mentor intervention for youth living with HIV aged 15-24 years in Ndola, Zambia. Using piecewise hierarchical linear modeling (HLM), change in internalized stigma predicted change in mindfulness, and mindfulness was a significant predictor of better self-reported adherence to antiretroviral therapy (ART) across both intervention groups. Intervention group membership did not predict rate of change in mindfulness, but predicted a reduction in internalized stigma and an increase in self-reported ART adherence. Following the peer mentor intervention, internalized stigma was significantly lower in the intervention group than the comparison group. Findings highlight the need to develop and implement interventions specific to adolescents living with HIV with a biopsychosocial approach that attends to both the physical and psychological needs specific to adolescents. Our findings support the inclusion of mindfulness-based components in interventions targeting ART adherence for adolescents living with HIV.

The current study of 151 college men explored weight-related factors that contribute to depressive symptoms among undergraduate men using structural equation modeling (SEM). Results of SEM supported the hypothesis that perceived negative messages about one's body and body dissatisfaction were significant mediators of the relationship between BMI and depressive symptoms. Moreover, social connectedness and academic self-concept were significant moderators of the relationship between body dissatisfaction and depressive symptoms. Although self-esteem was not a significant moderator, it was significantly related to body dissatisfaction, despite the men's magnitude of perceived body pressures. These findings inform therapeutic work with college men, signifying the importance of improving the quality of their relationships in family and social systems to reduce both depressive symptoms and body dissatisfaction. Furthermore, advocacy programming to counter body related pressure from media, societal systems, and other people would likely benefit college men struggling with body dissatisfaction and depressive symptoms.

Forensic researchers and practitioners continue to face challenges when attempting to differentiate deceptive response styles, notably when comparing malingering and factitious disorder. However, due to the great disparities in research available, forensic examiners may not be adequately informed for considering factitious presentations as a competing hypothesis to malingering. De-emphasis of factitious disorders may also be attributed to the lack of empirical research and poor conceptual understanding of the disorder. Velsor and Rogers conducted a thorough review of various factitious motivations, drawing a parallel to Rogers' explanatory models of malingering. Due to the need for a systematic measure of FPPs, the Inventory of Self and Interpersonal Problems (I-SIP) was developed, largely based on the explanatory models of FPP. The current study employed a construct validity approach to the I-SIP to examine its convergent and discriminant validity in a sample of 80 inpatients from a private psychiatric hospital. Providing strong evidence of construct validity of the I-SIP, dramatic differences emerged between malingered and factitious presentations with extremely large effect sizes (ds = 1.09 – 3.62). In particular, results indicated strong support for the nurturance explanatory model of FPPs, as over-investment in treatment providers was an especially strong discriminator (d = 3.62). Moreover, …

Using a strong invariance structural equation modeling approach, the current study explored the role of parental styles, along with age and IQ, on the expression of psychopathic personality facets in a large (N = 734) male sample of Hispanic and non-Hispanic offenders. Multiple group confirmatory factor analyses revealed evidence of strong invariance across ethnic groups for the psychopathy and parenting scales (CFI = .95; RMSEA .03). Person-centered analyses examining psychopathic versus non-psychopathic cases demonstrated that the former reported greater levels of dysfunctional parenting, particularly abuse. Structural equation modeling results highlighted differential relationships between the variables of interest as a function of race/ethnicity.

Positive affect, which has been broken down into four lower-level facets (i.e., joviality, attentiveness, self-assurance, serenity), has demonstrated numerous ties to physical and mental health. The experience of positive affect can be regulated by emotion regulation strategies. However, few studies have assessed their relationship, and no studies have examined the relationship using the lower level facets of positive affect. The link between positive affect and emotion regulation may be of particular importance for individuals at increased risk for bipolar disorder, as both are disrupted in individuals with the condition. The aim of the present study was to examine the relationship between positive affect and emotion regulation while also exploring whether risk for bipolar disorder moderated their relationship. Undergraduates (N = 155) completed measures of emotion regulation, affect, and bipolar disorder risk at baseline. Using ecological momentary assessment (EMA), participants completed surveys 3 times a day for 7 days. Hierarchical linear models were estimated and revealed significant effects between certain baseline emotion regulation tendencies (experiential avoidance/ psychological inflexibility, rumination, behavioral social avoidance) and daily positive affect facets as well as between daily emotion regulation use (i.e., reappraisal, acceptance, reflection, savoring, mindfulness social support, suppression, rumination, procrastination) and daily positive affect facets. …

The purpose of this study is to analyze the first movements of Sergei Bortkiewicz's two piano sonatas and compare them with works by other composers that may have served as compositional models. More specifically, the intention is to examine the role of the subdominant key in the recapitulation and trace possible inspirations and influences from the Classical and Romantic styles, including Mozart, Beethoven, and Schubert. The dissertation employs Schenkerian analysis to elucidate the structure of Bortkiewicz's movements. In addition, the first movement of Mozart's Piano Sonata K. 545, Beethoven's Coriolan Overture, and the first movement of Schubert's "Trout" Quintet in A, D. 667, are examined in order to illuminate the similarities and differences between the use of the subdominant recapitulation by these composers and Bortkiewicz.

This study investigated novice science and mathematics teachers' beliefs about planning and implementation of project-based instruction. Data for this qualitative study included two focus groups and a questionnaire. Items in the questionnaire were designed using preliminary findings from the analysis of the two focus groups, and from predefined items from the National Survey of Project Based Learning and High School Reform. The questionnaire was administered to 138 novice secondary mathematics and science teachers certified in their respective content areas. The respondent rate was 70% (n = 96). Of the 96 respondents only 28 participants utilized project-based instruction. Data analysis revealed that the 28 participants held two specific beliefs about project-based instruction. First, participants believed that the implementation and enactment of PBL: (a) made student learning more personalized by specifically meeting the individual interests or needs of students; (b) promoted students' international or cross-cultural understanding; (c) promoted students' civic engagement and contributions to the community or world; and (d) impacted high-achieving students ability levels. Second, participants believed that the implementation and enactment of PBL: (a) made teaching and learning more varied, challenging, or fun; (b) taught skills beyond academic content; and (c) taught academic content knowledge and skills more effectively. These …

The Dallas-Fort Worth International (DFW) Airport is located in a densely urbanized area with one of the fastest-growing populations in the U.S.A. The airport property includes a large tract of "protected" riparian forest that is unique to the urban surroundings. This dissertation explores variables that influence the benthic macroinvertebrate community structure found in urbanized prairie streams that were initially assessed by the University of North Texas (UNT) Benthic Ecology Lab during four, non-consecutive biomonitoring studies (2004, 2005, 2008, and 2014) funded by the DFW Airport. Additionally, land use analysis was performed using 5-meter resolution satellite imagery and eCognition to characterize the imperviousness of the study area watersheds at multiple scales. Overall, flow conditions and imperviousness at the watershed scale explained the most variability in the benthic stream community. Chironomidae taxa made up 20-50% of stream communities and outperformed all other taxa groups in discriminating between sites of similar flows and urban impairments. This finding highlights the need for genus level identifications of the chironomid family, especially as the dominant taxa in urban prairie streams. Over the course of these biomonitoring survey events, normal flow conditions and flows associated with supra-seasonal drought were experienced. Prevailing drought conditions of 2014 did not …

A collection of poems with a preface.

The implementation of professional learning communities (PLCs) has led to systemwide reform within school districts and campuses regarding how campus leaders support the teachers' collaborative work and continued professional learning. Current research emphasizes the importance of campus administrators cultivating an environment where PLCs can flourish and ensuring that PLC teams have the resources to work effectively. However, campus administrators simply putting these supports in place does not make them effective. This study sought to explore campus leader and teacher perceptions of administrator actions that support PLCs for teachers in core-content subjects at two suburban north Texas high schools. An explanatory sequential mixed methods research design was utilized, and three data collections tools were used: an electronic survey, interviews with campus administrators and teachers, and the analysis of campus and PLC artifacts. Survey data indicated that participating teachers had an overall positive perception of the current campus practices which support PLC teams. Teacher interview data revealed that teachers preferred that campus administrators take a neutral role in PLC team meetings, that administrators ensure PLC teams are meeting the established campus PLC expectations, and that administrators observe the team, listen, and ask questions to help the team. Campus administrators viewed their actions …

In urban environments, ozone air pollution, poses significant risks to respiratory health. Fixed site monitoring is the primary method of measuring ozone concentrations for health advisories and pollutant reduction, but the spatial scale may not reflect the current population distribution or its future growth. Moreover, formal methods for the placement of ozone monitoring sites within populations potentially omit important spatial criteria, producing monitoring locations that could unintentionally underestimate the exposure burden. Although air pollution affects all people, the combination of underlying health, socioeconomic and demographic factors exacerbate the impact for socially vulnerable population groups. A need exists for assessing the spatial representativeness and data gaps of existing pollution sensor networks and to evaluate future placement strategies of additional sensors. This research also seeks to understand how air pollution monitor placement strategies may neglect social vulnerabilities and therefore, potentially underestimate exposure burdens in vulnerable populations.

How do religions and nationalism interact in secular democracies? With its history of nationalism based on religious ideologies, and the subsequent forced separation of state and religion, Japan provides a valuable case to examine how religion and nationalism interact and affect the politics of a secular state. The purpose of this dissertation is to understand and synthesize the divide within the literature regarding the idea that Shinto is fundamentally nationalist in nature. Due to Shinto's historical ties to Japanese nationalism, it is clear that religion and nationalism played a role in Japanese politics in the past. However, with Japan's transition to democracy and the constitutional provision of the separation between religion and state, religion's effect on nationalism in Japan has become blurred contemporarily. In order to explore these relationships between Shinto, nationalism, and Japanese politics, I investigate how political groups and religious organizations influence nationalist sentiment in political institutions and public opinion in Japan using the Japanese Value Orientations survey and an original dataset. I find that even though the evidence is mounting against the accuracy around the idea of State Shinto and the fundamentally nationalist nature of Shinto, the narrative persists. The existence of nationalist circles perpetuates these narratives, …

This thesis includes three separate research projects focusing on computer vision principles and deep learning pattern recognition problems. Chapter 3 entails color quantization applications using traditional Kmeans clustering techniques and random selection of color techniques within the red, green, blue (RGB) color space to maintain a high-quality image while significantly reducing image file size. Chapter 4 consists of a handwriting character recognition algorithm using backpropagation to classify 70,000 handwritten values from US Census Bureau employees and high school students. Chapter 5 proposes a novel classification technique for 109,446 unique heartbeat samples to identify areas of interest and assist medical professionals in diagnosing heart problems.

In the past couple of decades, the zebrafish has been widely used to study hemostatic disorders. In this study, we generated a CRISPR/Cas9 mediated zebrafish mutant that contains a 55-nucleotide insertion in exon 29 of the von Willebrand factor (vwf) gene. The mutants had impaired ristocetin-mediated agglutination of whole blood, prolonged PTT and more bleeding in the lateral incision compared to wild-type fish. The bleeding phenotype observed here is similar to the phenotype observed in vwf knockout mice and patients with von Willebrand disease (VWD). The mutant model developed here can thus be used for exploring the role of Vwf in angiogenesis and for developing gene therapy. The deficiency of VWF causes VWD and the etiology remains unknown in 30% of Type 1 VWD cases. Previous studies have identified that the ABO blood group and ST3GAL4 (glycosyltransferases) are involved in the regulation of VWF levels. Since VWF is heavily glycosylated, we hypothesized that other glycosyltransferases may also be involved in regulating VWF. We performed a knockdown screen of 234 glycosyltransferase genes and identified 14 genes that altered Vwf levels. The sequencing of these genes in Type 1 VWD patients could help identify novel mutations to decipher the molecular basis for …

The structure and geometry of subspaces of a given Banach space is among the most fundamental questions in Functional Analysis. In 1961, Kadec and Pelczyński pioneered a field of study by analyzing the structures of subspaces and basic sequences in L_p[0,1] under a naturally occurring restriction of p, 2 < p <\infty. They proved that any infinite-dimensional subspace X\subset L_p[0,1] for 2<p<\infty must either be isomorphic to l_2 and complemented in L_p or must contain a complemented subspace which is isomorphic to l_p. Many works since have studied the relationships between the sides of this dichotomy, chiefly by weakening hypotheses on side of the equation to gain stronger assumptions on the other. In this way, Johnson and Odell were able to show in 1974 that if X contains no further subspace which is isomorphic to l_2, then it must embed into l_p. Kalton and Werner further strengthened this result in 1993 by showing that such an embedding must be almost isometric. We start by analyzing the tools and definitions originally introduced in 1961 and define a natural extension to these methods. By analyzing this extension, we provide a constructive and streamlined reproving of Kalton and Werner's theorem: Let X be …

The following thesis proposes solutions to problems in two main areas of focus, computer vision and machine learning. Chapter 2 utilizes traditional computer vision methods implemented in a novel manner to successfully identify overlays contained in broadcast footage. The remaining chapters explore machine learning algorithms and apply them in various manners to big data, multi-channel image data, and ECG data. L1 and L2 principal component analysis (PCA) algorithms are implemented and tested against each other in Python, providing a metric for future implementations. Selected algorithms from this set are then applied in conjunction with other methods to solve three distinct problems. The first problem is that of big data error detection, where PCA is effectively paired with statistical signal processing methods to create a weighted controlled algorithm. Problem 2 is an implementation of image fusion built to detect and remove noise from multispectral satellite imagery, that performs at a high level. The final problem examines ECG medical data classification. PCA is integrated into a neural network solution that achieves a small performance degradation while requiring less then 20% of the full data size.

In this dissertation, I examine the Sonoran Desert trilogy by Kathleen Alcalá through the lens of post-oppositional theory as developed by AnaLouise Keating. Moving beyond the use of post-oppositional theory to analyze non-fiction works, I apply this theory instead to the fiction of Kathleen Alcalá—whose work appears in such anthologies as The Norton Anthology of Latino Literature. Alcalá, though well published, is underrepresented in contemporary literary criticism, as can be seen by the only eight entries under her name in the MLA International Bibliography. Therefore, I have chosen her most significant fiction work, her trilogy about the Sonoran Desert, as the perfect text upon which to map post-oppositional theory. Through analysis of her three novels, I show that her work is an ideal example of post-oppositionality in action and that her characters act as post-oppositional revolutionaries and prophets within the pages of the text. The first chapter outlines the parameters of the project. In Chapter 2, I argue that post-oppositionality can be seen in Alcalá through gender bending, looking at the characters of Membrillo and Manzana, Corey, and Rosalinda. In Chapter 3, I argue that the characters of Estela, La Señorita, and Magdalena are enacting post-oppositionality through their transcendence of …

The dissertation examines factors influencing nonprofit organizations' contribution to collaborative governance for climate change adaptation and nonprofit roles in the collaboration. Why an organization collaborates with others has long been a concern of scholars. However, in a majority of empirical studies, collaboration has been considered as a dichotomous concept. To fill the gap, this study considers organizations' contribution to collaboration, i.e., collaboration level in terms of power, joint activities, human resource, funding, and information sharing. To understand contribution of nonprofits to collaboration for climate change adaptation, this research employs the institutional collective action framework suggesting that organizations work together when expected benefits are greater than collaborative risks. Survey data from 101 nonprofit private organizations (beyoungri mingan danche) in South Korea, which are legally defined in the Assistance for Nonprofit, Nongovernmental Organizations Act, are analyzed. Finding is that government funding and social relationship are strongly associated with nonprofit contribution to collaboration, highlighting that the financial stability of nonprofit organizations and mutual trust among entities based on routine interaction are critical motives for nonprofit collaboration. Finding also reveals that Korean nonprofits mainly play a role as social capital creators in climate change adaptation. The finding also highlights that Sang Bu Sang Jo …

Half of the students who begin college do not complete a degree or certificate. The odds of completing a degree are decreased if a student has a low socio-economic status (SES), is the first in a family to attend college (first-generation), attends multiple institutions, stops out multiple times, reduces credit loads over time, performs poorly in major-specific coursework, has competing family obligations, and experiences financial difficulties. Stopping out of college does not always indicate that a student is no longer interested in pursuing an education; it can be an indication of a barrier or several barriers faced. Institutions can benefit themselves and students by utilizing person-centered statistical methods to re-engage students they have lost, particularly those near the end of their degree plan. Using demographic, academic, and financial variables, this study applied latent class analysis (LCA) to explore subgroups of seniors who have stopped out of a public four-year Tier One research intuition before graduating with a four-year degree. The findings indicated a six-class model was the best fitting model. Similar to previous research, academic and financial variables were key determinants of the latent classes. This paper demonstrates how the results of an LCA can assist institutions in the decisions …
