The Resiliency Of Highly Mobile Military Children: Implications For Military And Education Leadership, Kim D. Hunt

Dissertations

The life of a highly mobile child brings educational and social challenges. Highly mobile children who move at least four to five times during their PK-12 grade years generally experience greater difficulty in their social interactions and education than children with a more stable living experience. One specific group of highly mobile children, military children, face these challenges and more, due somewhat to the unique culture of the military. Military children are called upon to move across state lines and/or international borders and typically face multiple school absences and stress related to deployments of their active duty parent(s). There is …

Is Self-Interest At The Root Of Political Behavior? An Examination Of The Effects Of Dark Personality And Demographics On Political Beliefs And Actions, Nathan A. S. Frishberg

Dissertations

Prediction of political behavior is of interest to scientists in the fields of psychology, sociology, and politics, as well as to the lay public. Previous research has connected personality to broad political leanings, but little if any published research has examined how personality relates to voting behavior. The current study built on earlier work by examining the connections among the Dark Triad of personality (psychopathy, narcissism, and Machiavellianism), demographics, specific political beliefs, and political behaviors. We hypothesized that dark personality would relate to political beliefs such that those higher on the Dark Triad would show stronger support for policies that …

The Role Of Multiple Dimensions Of Organized Activity Participation, Impulsivity, And Parental Monitoring On Externalizing Behavior Among Low-Income, Urban Adolescents., Amy Governale

Dissertations

Because the majority of teenage deaths are not due to illness, but instead attributed to risk behaviors, it is pertinent to determine under what circumstances adolescents are likely to injure themselves or others. One well-studied protective factor of adolescent externalizing behaviors is participation in organized activities. Unfortunately, the majority of research involving adolescents’ engagement in organized activities examines single dimensions of participation (intensity, duration, and breadth) at a time, within samples of middle-class, Caucasian youth. Few studies have examined how multiple dimensions of participation in organized activities, including how uninterrupted engagement in organized activities from school year to summer months, …

Best Practices In Global Mental Health: An Exploratory Study Of Recommendations For Psychologists, Kimberly Hook

Dissertations

This qualitative study aimed to provide best practice recommendations for psychologists who work within the field of global mental health. Global mental health seeks to improve mental health treatment equity on a worldwide scale, through mechanisms such as task shifting, advocacy on a governmental/community/systems level, and through capacity building. Global mental health is a growing field, and there have been calls for increased engagement in these efforts from the psychological community. Nevertheless, few recommendations are in place regarding how to practically move towards these goals in an ethical, culturally-relevant manner, though other related disciplines, such as psychiatry and public health, …

Antidepressant-Associated Sexual Dysfunction In Patients With Depression: A Meta-Analysis Of Sexual Functioning Data Collected Via Prospective Questionnaire, Paula Jacobsen

Dissertations

Sexual functioning is associated with symptoms of depression, which occurs at rates much higher than that in the general population. Treatment of depression and remission of depressive symptoms can improve sexual functioning; however, antidepressants and other medications may cause or worsen sexual functioning. Assessment of sexual dysfunction in the past has predominantly relied on the patient spontaneously reporting problems with sexual functioning to their physician or other medical professional. Due to the sensitive nature of the topic, patient reporting is typically low and does not reflect the actual prevalence of sexual dysfunction. This research assessed the rate and level of …

Application Of Synthetic Informative Minority Over-Sampling (Simo) Algorithm Leveraging Support Vector Machine (Svm) On Small Datasets With Class Imbalance, Akshatha Fakkeriah Kallappanamatt

Dissertations

Developing predictive models for classification problems considering imbalanced datasets is one of the basic difficulties in data mining and decision-analytics. A classifier’s performance will decline dramatically when applied to an imbalanced dataset. Standard classifiers such as logistic regression, Support Vector Machine (SVM) are appropriate for balanced training sets whereas provides suboptimal classification results when used on unbalanced dataset. Performance metric with prediction accuracy encourages a bias towards the majority class, while the rare instances remain unknown though the model contributes a high overall precision. There are chances where minority instances might be treated as noise and vice versa. (Haixiang et …

Classification Using Association Rules, Colin Kane

Dissertations

This research investigates the use of an unsupervised learning technique, association rules, to make class predictions. The use of association rules to make class predictions is a growing area of focus within data mining research. The research to date has focused predominately on balanced datasets or synthetized imbalanced datasets. There have been concerns raised that the algorithms using association rules to make classifications do not perform well on imbalanced datasets.

Identifying Cross-Country Key Drivers Of Social Entrepreneurial Activity, Cris Bravo

Dissertations

Governmental and philanthropic efforts alone are not sufficient to eradicate poverty. The world needs new frameworks that enable sustainable development by integrating the economic, social and environmental dimensions, and social entrepreneurship is of great interest because it has the capacity for facilitating societal change by fostering innovative ways to address social inequality, unemployment, and climate change. Precisely because social entrepreneurship lays at the intersection of the business and nonprofit worlds, it is a complex phenomenon, and there are many unknowns regarding how the convergence of these dimensions can be understood and managed at cross-national levels.

To investigate this phenomenon, this …

Dissertations

Purpose

The purpose of this study was to determine if the 6 personality Types, as measured by Grossarth-Maticek and Eysenck’s (1990) Short Interpersonal Reactions Inventory (SIRI), were present in a sample of cancer and cancer-free individuals and to examine if the Type 1 personality category (cancer-prone personality) could significantly differentiate cancer from cancer-free subjects. Using an ex post facto research design and a sample of 648 English speaking adults selected from North America, overall findings from a confirmatory factor analysis suggested that contrary to results from some prior studies which validated the 6-personality factor structure of the SIRI, the six …

The Roles Of Hpa Axis Activity And Attentional Bias In The Development Of Anxiety Symptoms In Low-Income Mexican-Origin Children, Stephanie Brewer

Dissertations

The overarching goal of this research is to increase understanding of the development of anxiety in children of low-income Mexican-origin immigrants. Mexican-origin children display disproportionately high rates of mental disorders such as anxiety, as they face many chronic stressors related to poverty and immigration. A likely mediator of this process is HPA axis activity, causing a buildup of cortisol in the body in response to chronic stress. There is a large amount of evidence indicating that HPA axis activity is a mechanism through which accumulated poverty-related stress causes mental illness, but this mediator has not been examined in relation to …

Trauma-Focused Cognitive Behavioral Therapy With A Teacher Component: Outcomes Examined In A School Setting, Kelly Marie Holmes

Dissertations

Trauma exposure among youth is common and can result in long-term social-emotional, behavioral, and academic problems (Finkelhor, Turner, Hamby, & Ormrod, 2011; Kronenberg et al., 2010). Fortunately, there are interventions that can ameliorate these problems. In particular, trauma-focused, interventions are effective in reducing trauma related symptomatology and problems among youth (Cary & McMillen, 2012). Trauma exposure among youth is common and can result in long-term social-emotional, behavioral, and academic problems (Finkelhor, Turner, Hamby, & Ormrod, 2011). Additionally, most youth receive mental health services in schools (Green et al., 2013). Fortunately, there are school-based, trauma-focused interventions that have been found to …

Cultural Assets And Racial Discrimination: A Person-Based Exploration Of Culturally Relevant Coping With African American Male Adolescents, Emma-Lorraine Baaba Bart-Plange

Dissertations

African-American youth from economically-disadvantaged, urban families and communities are disproportionately exposed to stressful life conditions, including racial discrimination, placing them at increased risk for mental health problems (Gonzales & Kim, 1997; Grant et al., 2000). Though exposure to racial discrimination can span a lifetime, examining youths’ encounters with discrimination during adolescence allows us to better understand how they affect development during a critical period in which they are developing racial/ethnic identity and increasing their use of reasoning. Coping research with African American youth has found evidence for racial discrimination predicting use of culturally-relevant coping strategies (Gaylord-Harden & Cunningham, 2009) and …

Entre Dos Tierras: Between Two Lands: Stories Of Latinx Immigrant Students In Us Public High Schools, Yahaira Diaz

Dissertations

The election of the 45th president of the United States has increased a sense of anxiety, fear, and xenophobia for many in our country. The divisive campaign and current discussion of policy is demeaning towards LGBT communities, people with disabilities, women, and ethnic minorities, specifically the immigrant population. The nation’s current preoccupation with and much deserved attention towards a comprehensive immigration reform and the continuance of immigration into the United States has impacted the rise of anti-Hispanic hate crimes and xenophobia (Shihadeh & Barranco, 2013; Stacey, Carbone-Lopez, & Rosenfeld, 2011; Yakushko, 2009). Educators report an increase in hostility against immigrants …

Social Scientists' Conceptualization And Implementation Of Research Ethics And Integrity, Heather A. Pease

Dissertations

The purpose of the current study is to identify core themes, values, and principles through which social scientists conceptualize and implement research ethics and integrity. Periods of rapid growth and interest in research ethics and integrity often coincide with significant scientific discoveries (e.g., mapping of the human genome) or scientific misconduct (e.g., Tuskegee studies). Even though research policies are being developed, they are done in a manner which does not maximize the opportunities to regulate ethics and integrity within social science research. The laws and programs aimed at mitigating acts of misconduct were originally intended for biomedical sciences, yet they …

Socio-Ecological Moderating Factors In The Grit-Academic Achievement Relationship, Keeshawna Brooks

Dissertations

There has been a recent focus in research on a concept that centers on an individual’s ability to be persistent in the pursuit of their goals. This concept, referred to as grit, is an addition to the conversation about noncognitive measures that show promise to positively affect student academic performance. However, with the salient focus on the individual qualities that contribute to student success, it is important to avoid looking at these student qualities in isolation from the socio-ecological milieu (Ysseldyke, Lekwa, Klingbeil, & Cormier, 2012). Situating individual student qualities within Bronfenbrenner’s socio-ecological framework can be particularly helpful when seeking …

Protocol For Energy Efficient Cluster Head Election For Collaborative Cluster Head Elections., David Otu

Dissertations

In wireless sensor networks (WSNs) , energy is a major constrain.Energy efficient network protocols is required to maintain reliable sensing of the sensing field . WSNs that use LEACH protocol, have node in a cluster periodically take trials to become cluster - head,such that the nodes in the cluster becomes cluster - head evenly. Nodes with greater transmission distance to the base station in the cluster dies out faster because it performs more work in transmitting data when it is cluster-head. The distance-based algorithm presented in this project, ensures that work is allocated to the nodes in the cluster more …

Can Threshold-Based Sensor Alerts Be Analysed To Detect Faults In A District Heating Network?, Liam Cantwell

Dissertations

Older IoT “smart sensors” create system alerts from threshold rules on reading values. These simple thresholds are not very flexible to changes in the network. Due to the large number of false positives generated, these alerts are often ignored by network operators. Current state-of-the-art analytical models typically create alerts using raw sensor readings as the primary input. However, as greater numbers of sensors are being deployed, the growth in the number of readings that must be processed becomes problematic. The number of analytic models deployed to each of these systems is also increasing as analysis is broadened. This study aims …
