Structural And Cognitive Correlates Of Body Mass Index In Healthy Older Adults, Jacob Bolzenius

Dissertations

Obesity, commonly measured with body mass index (BMI), is associated with numerous deleterious health conditions and may be a modifier of age-related alterations in brain integrity. Research suggests that white matter integrity observed using diffusion tensor imaging (DTI) is altered with high BMI, but the integrity of specific tracts remains poorly understood. Additionally, no studies have examined fractional anisotropy (FA) of tract integrity in conjunction with neuropsychological evaluation with elevated BMI among older adults. It was hypothesized that elevated BMI would be independently associated with lower white matter integrity and cognitive performance. It was also hypothesized that age and BMI …

The Relation Of Anxiety, Depression, And Stress To Binge Eating Behavior, Diane L. Rosenbaum

Dissertations

Binge eating is an impairing and prevalent problem. Theories of binge eating suggest negative affect is of primary importance in the development and maintenance of binge eating behavior. To date, investigations of binge eating have often examined depression, however relatively little is known about other psychological factors. The current study aimed to extend the literature by examining several psychological factors in relation to binge eating behavior. Specifically, the relation between binge eating behavior and three psychological factors, depression, anxiety and stress, were examined. Data were collected via online surveys from a community sample of men and women of diverse backgrounds. …

Organizational Interventions For Restoring Justice In The Workplace, Wanyi Ma Lai

Dissertations

This study examined the impact of organizational interventions in the aftermath of a workplace injustice. Using restorative justice theory, I explored how four different interventions may differentially impact a victim’s levels of forgiveness, reconciliation, revenge motivation, and avoidance motivation. It was found that not acknowledging an injustice had taken place could lead to increased revenge motivation or avoidance behaviors, which could be potentially counterproductive in a work environment. On the other hand, results indicated that an important element of minimizing undesirable responses and increasing the potential for positive responses could be extending a sincere apology for the transgression. Forgiveness was …

An Evaluation Of Various Safmeds Procedures, Shawn Patrick Quigley

Dissertations

Lindsley developed Say-All-Fast-Minute-Every-Day-Shuffled, or SAFMEDS, in the late 1970’s to enhance the typical use of flashcards (Graf & Auman, 2005). The acronym was developed specifically to guide the learner’s behavior when using flashcards. A review of SAFMEDS research indicates it has been utilized with children, college students and older adults with and without disabilities. The literature also indicates the SAFMEDS procedures used are not well documented or have multiple variations limiting practitioners’ ability to know what procedure to use and when. Furthermore, future SAFMEDS research is hampered by variations in the independent variable (i.e., SAFMEDS). The purpose of this study …

Testing A Model Of Maladaptive Perfectionism And Depression Symptoms: The Roles Of Emotional Disclosure, Emotion Regulation Strategies, Adult Attachment, And Shame, Angela M. Garrison

Dissertations

Previous research has supported a link between maladaptive perfectionism and higher levels of depression symptoms. However, researchers have not yet investigated the ways in which emotion regulation processes may mediate this relationship. Therefore, the primary purpose of this study was to evaluate emotional disclosure, emotional avoidance, and rumination as mediators of the relation between maladaptive perfectionism and depression symptoms. Additionally, this study also investigated the role that insecure attachment orientations play in the relationship between maladaptive perfectionism and use of particular emotion regulation strategies. Further, the role of shame in the emotion regulation processes of individuals with higher levels of …

Beyond Biracial: The Complexity Of Identity Construction For Women With One Black And One White Parent, Roxanne Kymaani

Dissertations

In the United States, the post-Civil Rights Movement era changed forever the social perceptions about race and the self-perceptions of people who are born with mixed racial origin. Choosing to identify as mixed race in America inevitably leads to a racial cross-examination linked to America’s continued struggle with its racial heritage and the enduring legacy of a dominant discourse.

This dissertation focuses on the lived experience of women with one Black and one White parent. While subject to labels such as Black and White, Black, mulatto, biracial, mixed, or other, the central question is what do these women wish to …

Exploring Job Stress Among Drug Court Personnel, Ragan Andrew Downey

Dissertations

In the field of criminal justice, much research has been devoted to exploring job stress among corrections staff, police officers, and individuals working in legal professions. Additionally, there is an abundance of research regarding drug courts and their impact on the justice system. There is, however, a stark absence of research concerning job stress among drug court personnel. This study was designed to fill that gap in the existing literature by examining the perceptions of drug court personnel regarding job stress, job satisfaction, and other relevant factors identified in the literature. Results of bivariate and multivariate analyses indicated that drug …

The Influence Of Bystanders In Subsequent Bullying Behavior, Jenny Lane Morris

Dissertations

Aggression that is targeted towards an individual or a group of individuals who is at a disadvantage to respond is known by several terms in the literature, including bullying, harassment, and mobbing. There has been much interest in this sort of targeted aggression among school-aged children and, therefore, a large body of literature on the topic exists. In adult populations, especially in workplace environments, much research has focused on the respective roles of the victim and bully in this adverse social dynamic, with less information available on the role of the bystander, which has emerged as an important part of …

Divorce And Forgiveness: A Comparison Between Genders, Alison Kathleen Johnson

Dissertations

Divorce has become more commonplace throughout time. This study was conducted to determine if there were any differences between genders concerning forgiveness of their ex-spouses. Four instruments including the Enright Forgiveness Inventory, Fisher Divorce Assessment, Learning Activities Survey, and structured qualitative interviews were used to determine the differences specifically with regard to how men and women forgive and at what rate they forgive.

The sample included divorced adults employed by the Mississippi Department of Mental Health and graduate students in the Department of Educational Studies and Research at a local university. A total of 31 completed surveys were returned, and …

Who Will Defy Authority? Personality Features And Destructive Obedience In The Milgram Paradigm, Ashton Caroline Southard

Dissertations

The present study examined the potential role of individual differences in personality in the likelihood of engaging in destructive obedience to authority within a modified version of the Stanley Milgram paradigm (Milgram, 1963, 1974). Personality features examined included the Big Five dimensions of agreeableness, openness, neuroticism, conscientiousness, and extraversion, and the dimensions of the Dark Triad, which consist of narcissism, psychopathy, and Machiavellianism (Paulhus & Williams, 2002). Participants were 39 undergraduates enrolled in introductory psychology classes who participated in exchange for partial fulfillment of a research requirement. Data were collected in two phases. Phase 1 consisted of online completion of …

The Romance Of Leadership: Construct Clarification And Its Relationship With Reactions To Organizational Change, Cari Lois Rottman

Dissertations

Leadership involves the dyadic relationship between a leader and his or her followers. As such, the thoughts and attitudes of followers are an integral part of this relationship. Romance of leadership (ROL) is the degree to which followers believe that leadership “is the premiere force in the scheme of organizational events or occurrences” (Felfe, 2005; Meindl & Ehrilich, 1987). The current research examined ROL by looking at 1) the dimensionality and construct validity of ROL, 2) the difference between explicit and implicit measurement of ROL, and 3) the relationship between ROL and evaluations of leader effectiveness in a changing environment. …

Use Of Task Clarification, Feedback, And Recognition To Increase Desired Behaviors Within An Organization’S Permit To Work System - Analysis Of Data Previously Collected As An Organizational Consultant, Tarek Abousaleh

Dissertations

The term ‘culture’ can be used to describe both a ‘social culture’ and a ‘work culture’. A social culture can be defined behaviorally as a pattern of overt and covert behaviors that are consequated by the verbal community and the contingency specifying rules that facilitate behavior independent of any first hand experience. It is this community that defines which behaviors are reinforced, extinguished, or punished. Similarly, a work culture can be defined as a pattern of overt and covert behaviors that are consequated by the work community (leadership, employees, self, etc.) and the contingency specifying rules that facilitate behavior/performance independent …

Examining The Operant Function Of Feedback: Evaluation Of The Temporal Location Of Feedback, Elian Aljadeff-Abergel

Dissertations

Despite the common use of feedback in most training settings, it is not yet clear what behavioral function feedback serves. Most researchers consider feedback to function as a consequence and advocate for its immediate delivery in the form of “on the spot” supervision or after-session conferencing. The literature suggests that when compared, “on the spot” supervision is found more effective than after session conferencing. In spite these findings, most supervisors are still implementing after-session conferencing. This is probably due to the limited feasibility of performing “on the spot” supervision when supervising teachers implementing whole class or small group instruction. One …

Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen

Dissertations

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …

A Longitudinal Look At Electronic Mentoring Relationships, Lyndsey Marie Havill

Dissertations

Current advancements in information technology are increasingly impacting work relationships. Rapid technological changes have significant implications specifically for workplace mentoring because they may offer faster and more economical ways of building relationships. However, the e-mentoring literature is still evolving, and the extent to which e-mentoring parallels face-to-face mentoring is unknown. The purpose of this study was to investigate the development of mentoring functions over time and how the development varies depending on the amount and type of computer mediated communication. While career-support was greater at initial points in the relationship, psychosocial-support increased at a greater velocity for mentors. Bandwidth and …

Attitudes And Beliefs Of Seventh-Day Adventists Concerning Psychology, Counseling, And Mental Health Issues, Kristy Koeppe

Dissertations

Problem. As in the mainstream population, Adventists are dealing with a variety of mental health issues, and there has been no empirical research which explored their attitudes and beliefs concerning psychology, counseling, and mental health issues.

Method. A survey was used to collect data on beliefs about psychology, attitudes towards counseling, beliefs about mental health issues, and beliefs about medical care from a sample of 317 Adventist adults from the Illinois Conference. Data were also analyzed to understand the relationship between the independent variables—gender, utilization of psychological services, the Seventh-day Adventist’s degree of knowledge about the writings of Ellen G. …

Dissertations

Problem and Purpose

The U.S. Army has changed radically in the 68 years since World War II ended, from uniforms to vehicles, from weaponry to organizational changes. While still the Army, its workforce has changed greatly in gender, ethnic, and age composition. John Bruce, Jr. saw many of these changes during his 69-year career as both soldier and executive. How this leader responded to the changes in the U.S. Army over nearly seven decades was the problem I explored. The purpose of the study was to describe how 94-year-old John Bruce, senior executive at the U.S. Army’s Tank-automotive and Armaments …

Factors That Relate To Registered Nurses' Readiness For Interprofessional Learning In The Context Of Continuing Professional Development, Collette Williams

Dissertations

Today’s health-care professionals practice in a highly technological, multidisciplinary environment. In order to provide safe, effective, and high-quality patient care, collaboration is required among all professionals. Traditionally each profession has operated independently in regard to continued professional development. The purpose of this study was to assess practicing registered nurses’ readiness toward interprofessional learning in order to align learning with current practice.

Method. An ex post facto study design was used to gather data to examine if there is a relationship between variables of demographics and readiness for interprofessional learning. The Readiness for Interprofessional Learning Scale (RIPLS) assesses the readiness for …

Dissertations

Problem and Purpose

Innovative solutions in national defense are needed to respond to national security threats in our uncertain environment. Leader attitudes and behaviors have a substantial impact on innovation. Unfortunately we did not completely understand the effect of leader attitudes and behaviors on innovation and the team dynamics that lead to innovation, especially in the military. The purpose of this study was to determine how leadership attitudes and behaviors contribute to product innovation within the U.S. Navy and how leadership emerges within this complex adaptive system of innovation.

Method

The research was a qualitative design based on a multiple …

Effects Of Cultural Awareness Training In Conjunction With An Established Bullying Prevention Program, Megan Kallie Polanin

Dissertations

While many school bullying prevention programs have been designed to thwart school bullying perpetration, victimization, and physical aggression, empirical support is limited. To date, few researchers have addressed bullying within the context of children's cultural systems, and cultural awareness training has not yet been utilized as a mechanism to decrease bullying behaviors in the context of school bullying prevention programs.

This study examined the utility of incorporating multicultural training aimed at reducing prejudice within the context of school bullying prevention programming efforts within a diverse educational setting. This researcher hypothesized that the addition of meaningful culture curriculum would further reduce …

Impact Of First Disclosure Experience And Internalized Stigma On Disclosure Patterns In The Hiv+ Community, Mary Elizabeth Talbot

Dissertations

The present study examined possible antecedent factors that contribute to the type of discloser (HIV status) one becomes as well as the relation between discloser type, social support, and CD4 count. This study builds off previous research by Stutterheim et al. (2011) that examined differences between disclosure groups on a variety of variables, but the study did not examine variables that may contribute to the type of discloser a person becomes. The present study examined two variables that previous research suggests may influence the type of discloser (relative non-discloser, selective discloser, full discloser) a person becomes, first-disclosure experience, and internalized …

The Hidden Costs Of Success: A Mixed Methods Approach To Examining Achievement Pressures In Affluent Youth, Lea Ventura Travers

Dissertations

Within the last ten years, researchers have begun to recognize that youth from affluent backgrounds report elevated adjustment problems (Csikszentmihalyi & Schneider 2001; Luthar & Lantendresse 2005a), yet contributing factors have rarely been investigated. The present study explored various parenting variables and their influence on adolescents from affluent communities, including two parent-focused parenting variables (i.e., parental perfectionism and parent life satisfaction) and three adolescent-focused parenting variables (i.e., perceived parental pressure, parents' future goals for their children, and parental involvement in their children's lives). Using a mixed methods approach (i.e., quantitative and qualitative data), both linear and curvilinear relations between parenting …

Predicting Emotion Regulation In Early Childhood: The Impact Of Maternal Well-Being, Infant Crying, And Dyadic Mutuality, Tiffany Burkhardt

Dissertations

Learning adaptive emotion regulation skills in early childhood has been identified as fundamental to social competence, academic success, and psychological well-being. Because children learn to regulate their emotions through interactions with their caregivers, dyadic mutuality between the mother and infant may influence child emotion regulation capacity more than maternal behavior alone. To better understand the impact of maternal well-being and infant crying on the development of emotion regulation, parenting stress, maternal self-efficacy, maternal depression, and infant crying were examined with dyadic mutuality in the parent-child interaction to predict emotion regulation capacity.

A racially and socioeconomically diverse community sample of 149 …

Remember The Good Times: Does Savoring A Previous Intergroup Interaction Increase Whites' Positive Intergroup Emotions And Willingness To Develop Future Intergroup Friendships?, Patrick R. Harrison

Dissertations

Although racial prejudice remains a prevalent social phenomenon, research has demonstrated that positive contact - most notably intergroup friendship - predicts decreased prejudice. Whites, however, may be hesitant to develop intergroup friendships because they experience negative emotions like anxiety when faced with the prospect of interacting with outgroup members (i.e., Blacks). Past research has countered this obstacle by relying on manipulations that reframe how individuals feel about intergroup interactions to increase willingness to engage with outgroup members. Building on this framework, I tested whether savoring a previous intergroup interaction could increase friendship willingness by increasing positive intergroup emotions (Study 1) …

Expertise, Democratic Values, And Tolerance, Erika D. Price

Dissertations

Political tolerance (the willingness to extend civil liberties to disliked groups) has been disturbingly low among the American public since measurement of tolerance began in the 1950's. The few voters who do exhibit tolerant attitudes tend to be people who know a great deal about politics (i.e. people high in "political expertise"). Researchers have theorized many explanations for why political experts are more tolerant on average; for example, experts may place more value on the legal and normative `rules' of democracy (i.e. "democratic norms"), which guarantee free speech, or they may consider democratic norms to be more important than non-experts …

The Affective Consequences Of Expressing Moral Convictions, Lisa Diana Sandberg

Dissertations

This project examined the affective consequences of expressing moral convictions to an opposing majority. It was predicted that moral conviction would function as a buffer to the common negative emotions that occur when speaking out against majority opinion (e.g., fear; Asch, 1956; Berns, et al., 2005). It was also hypothesized that moral conviction would enhance positive feelings among those who speak out (e.g., pride). Two studies were conducting using two different research paradigms. Study 1 used a normative influence paradigm modeled after Hornsey, Smith, and Begg (2007). Participants' opinions and strength of moral conviction about the target issue (torture of …

The Effects Of Racial Identity On African American Youths' Psychosocial Adjustment: A Conceptualization Of The Literature And Meta-Analytic Review, Corinn Elmore

Dissertations

There is a general assumption of the positive effect of racial identity on the psychosocial adjustment of African-American youth. Despite this assertion, research findings for racial identity are unclear. The disparate measures of racial identity were organized into a cohesive framework with eight categories. Using this conceptual framework, a meta-analytic review was conducted on the effects the components of racial identity on African-American adolescents' psychosocial adjustment. There were 58 independent samples from 34 published journal articles and 14 unpublished papers (dissertations) including a total of 14,209 youth included in the study. Results of study highlight the importance of racial pride …

Sorority Women & Eating Pathology: Communities Of Unhealthy Body Standards?, Ashley Marie Rolnik

Dissertations

The present study examines disordered eating, sorority social norms regarding the body and thinness, personal values regarding the body and thinness, body dissatisfaction, thin ideal internalization, fat talk, negative affect, and positive affect among sorority and non-sorority women. The aims of this study are to discern the underlying factor structures of the sorority/group social norms questionnaires and the personal values regarding the body and thinness questionnaire, investigate disordered eating among sorority and non-sorority women over time, and further examine the impact of social norms on sorority women's body and eating attitudes and behaviors. The results of this research illustrated three …

Closing The "Revolving Door": Identifying Predictors Of Time To Rehospitalization In A Sample Of Psychiatric Inpatient Youth, Alison Merri Stoner

Dissertations

Previously a long-term mental health treatment option, inpatient psychiatric care is now an acute service for brief crisis stabilization and psychiatric reconstitution. Although lengths of stay have declined, rehospitalization rates have risen, calling into question the effectiveness of inpatient treatment and the extent to which inpatient and post-discharge, community-based services are working together to promote community tenure for youth. The present study had three aims: (1) evaluate the utility of the Child and Adolescent Needs and Strengths (CANS; Lyons, 1999) as an outcome assessment and decision support tool for youth inpatient hospitalization, (2) confirm a social ecological theory-informed factor structure …

Vascular Risk, Functional Connectivity, And Episodic Memory In Older Adults, Elizabeth Regina Tuminello Hartman

Dissertations

Resting-state functional magnetic resonance imaging and functional connectivity (FC) analyses are used to explore functional brain networks underlying a diverse array of abilities. Functional networks are composed of regions throughout the brain whose activity is closely linked to form a coherent network. One functional network, the "default mode network" (DMN), is thought to subserve self-referential thought and autobiographical memory. DMN regions include the ventromedial prefrontal cortex, inferior parietal lobe, hippocampus, and the primary "hub" of this network, the posterior cingulate cortex (PCC). For reasons yet unknown, DMN FC declines in aging, which is associated with memory impairment. Vascular risk may …
