Effects Of D-Galactose Treatment And Moderate Exercise On Spatial Memory In Rats, Amanda R. Austin

Dissertations

Cognitive decline is a process frequently associated with aging. Physical exercise appears to counteract cognitive decline, specifically spatial abilities, and decreases the effects of reactive oxygen species (ROS) associated with aging. In addition, brain derived neurotrophic factor (BDNF) and glial derived neurotrophic factor (GDNF) are well recognized as chemical mediators of the neurophysiological benefits of exercise.

In order to study the impact of exercise on spatial memory and neurotrophic factors, this study utilized an animal model of accelerated aging involving chronic d-galactose administration. Specifically, previous research indicates daily injections of d-galactose for 6-10 weeks may increase ROS in mice and …

An Evaluation Of Social Capital's Effect On Depression Among Adolescents, Ezechukwu Awgu

Dissertations

Mental illness has been described as a “global burden of disease,” and depression accounts for a large part of the burden (Aslund, Starrin, Nilsson, 2010). In 2009, 35.7 percent of the adolescent population in the United States who reported past-year symptoms of a major depressive episode, for example, feelings of sadness, discouragement, loss of feelings of self-worth, and loss of interest in social activities, also used illicit drugs including marijuana, inhalants, hallucinogens, cocaine, heroin, and prescription-type psychotherapeutics for non-medical purposes (SAMHSA, 2009, APA, 1994). Additionally, substance abuse due to alcoholism was among the major causes of death for adolescents aged …

Identifying In-School Predictors Of Postsecondary Success For Students With Hearing Impairments, Jennifer Lynn Coyle

Dissertations

Students with hearing impairments are historically a low incidence disability group. Gaps in knowledge of evidence-based practices for implementing transition education and services for this population is limited, primarily as a function of the size of the population; they have not received much attention from the educational research community. Students with hearing impairments often experience more successful outcomes in postsecondary education and employment than other disability groups, but less than those without a disability; however, we know little of the specific educational experiences associated with such success. In contrast, a body of work on predictors of post-school success for students …

Rule-Based Precise Localization Services In Mobile Environments, Mohammed Elbes

Dissertations

In recent years there has been great interest in the positioning of people and assets in indoor and outdoor environments. Many systems were constructed to accomplish this. The application of these systems depends on the environment and the precision required for localization. The Global Positioning System (GPS) cannot be used for a precise indoor localization due to the attenuation and scattering of the signals. For indoor environments, other technologies like Wireless LAN, laser, camera images and motion sensors are used in precise localization. GPS can be used in outdoor environments but if localization accuracy is a critical requirement, other technologies …

Equine-Assisted Psychotherapy: A Descriptive Study, Erica Jex Gergely

Dissertations

The current study seeks to examine the program operations and treatment practices of individuals and organizations providing equine-assisted therapy services nationwide. Currently, there are several hundred programs across the United States that utilize equine-assisted therapy to treat common mental health problems in children, adolescents, and adults. Not all equine therapy programs function under the same theoretical model and therefore do not deliver treatment services using equivalent principles or techniques. In addition, program policies, procedures, and ethical guidelines of each provider vary. To date, there exists a paucity of research regarding equine-assisted therapy including both qualitative and quantitative data.

The present …

Using Box-Jenkins Modeling Techniques To Forecast Future Disease Burden And Identify Disease Aberrations In Public Health Surveillance Report, Larry C. Garrett

Dissertations

The analysis of public health surveillance data to identify departures from historical patterns of disease is required to facilitate the timely identification of potential outbreaks. Using the Box-Jenkins forecasting model, this study examines the potential to predict future disease burden based upon the historical record within local public health jurisdictions. Box-Jenkins forecasting was developed as a direct result of forecast problems in the business, economic, and control-engineering applications, yet it has not been systematically examined for use with public heath surveillance data.

Box-Jenkins forecast models are constructed by stratifying 84,029 disease reports from the State of Utah by year (n …

Experiences Of Suburban And Rural High School Principals Who Have Attained Longevity In The Position: A Qualitative Study, Peggy A. Mathis

Dissertations

Today’s school leaders face many challenges. There is a renewed need to look at principal’s job satisfaction and longevity given recent trends in burnout, increased accountability, and a shortage of qualified candidates. There are conflicting demands on high school principals’ time and capacity. These leaders still have the traditional responsibilities of ensuring a safe environment, managing a budget, and maintaining discipline. Higher expectations for student success have brought with them an increase in school program expectations (DiPaola & Tschannen-Moran, 2003).

The job of the principal has changed throughout the years (DiPaola & Tschannen-Moran, 2003; White-Smith & White, 2009). The shift …

Examining The Role Of Research Mentoring In Predicting Research Self-Efficacy Among Minority Professional Psychology Doctoral Students, Donald Edward Knight

Dissertations

The involvement of racial/ethnic minority doctoral students in the conduct of psychological research is of significance in meeting the mental health challenges of an increasingly diverse US population.

Traditional And Market-Based Financial Intermediaries: Three Essays Examining Their Risk Behavior, Delisting Behavior, And Reactions To Economic Policy Uncertainty, Marc S. Schaffer

Dissertations

In the wake of our country’s greatest financial crisis since the Great Depression, the need to better understand the risks and behaviors associated with financial intermediaries has become apparent. In particular, the literature distinguishes between traditional or depository-based financial intermediaries and their market-based or non-depository counterparts. This dissertation focuses on understanding the behavioral differences across these two groups by examining their equity-based risk differences, their stock market delisting differences, and lastly how these firms react to economic policy uncertainty.

The first essay uses an equity-based approach to quantify the average firm-level risk that is associated with these intermediary groups. While …

This study examines the transfer of electronic waste (e-waste) from core to peripheral nations, specifically coastal nations in Africa. The theoretical perspective marries green criminology with world systems theory in examining the ways in which marginalized populations bear the burden of hazardous waste disposal across the globe. The study is comparative, looking at legislation in the United States as well as international legislation and enforcement, and also employs case study methodology, contrasting e-waste disposal in Nigeria and Ghana. The final intent of this research is to determine whether or not the violation of national and/or international legislation regarding the transfer …

Female Head Athletic Trainers In Ncaa Division I (Ia Football) Athletics: How They Made It To The Top, Joanne Gorant

Dissertations

The profession of athletic training has opened its doors to women, who now slightly outnumber men in the profession (Shingles, 2001; WATC, 1997, 2005). Unfortunately, this representation does not carry over into positions of high rank. The purpose of this qualitative study was to examine the lived experiences of female head athletic trainers in NCAA Division I (IA football) institutions to focus on the issues of barriers to advancement and their ability to overcome them.

Using Hakim’s “preference theory” as a lens, this interpretive qualitative investigation utilized semi-structured, open-ended interviews to learn how participants advanced in the field of athletic …

The Relationship Between Teacher Classroom Practices And 21st Century Students' Academic Dishonesty At The Secondary Level, Marguerite Beth Bellipanni

Dissertations

With the rise in the number of high schools students admitting to academic dishonesty on national surveys, educators must examine what is happening in the classroom to determine a cause for this increase. Past research has shown that students cheat for a variety of reasons. Much of it has shown that students are able to neutralize their cheating to external reasons such blaming the teacher, competition for good grades, or not understanding the task at hand. The literature has also revealed that students cheat because they feel that there is no enforcement of consequences for academic dishonesty.

The purpose of …

Mortality Salience And Worldview Defense, Toni Brooke Merkey

Dissertations

Research generated from Terror Management Theory has demonstrated that reminding participants of their eventual death increases self-esteem striving and worldview defense (Pyszczynski, Greenberg, Solomon, Arndt, & Schimel, 2004). The hypothesis in the present study is that individuals higher in emotion dysregulation will engage in higher levels of worldview defense than those lower in emotion dysregulation. This hypothesis was based on the assumption that individuals high in emotion dysregulation will have a greater need to regulate their emotions by engaging in worldview defense after being asked to think about their own death than will non-emotionally dysregulated individuals. To test this hypothesis, …

The Use Of Time-Out With Escape Extinction To Reduce Noncompliance Maintained By Escape Or Attention, Shelly Renee Benshoof

Dissertations

The present study examined the effectiveness of Time-Out with Escape Extinction (TO-EE) to reduce escape-maintained noncompliance and attention-maintained noncompliance through the use of four contingency reversal designs in a clinical setting. Four parent-child dyads served as participants. Screening procedures identified four children with low levels of compliance to first time issued, parent instructions. Functional analysis procedures identified two children who exhibited escape-maintained noncompliance and two children who exhibited attention-maintained noncompliance to serve as participants. Parents were trained in the implementation of screening, functional analysis, baseline, TO-EE, and contingency reversal procedures. Results indicated that TO-EE is effective at establishing compliance levels …

Further Validation Of The Child Routines Questionnaire: Child Self Report, Christina Binder Stabler

Dissertations

There has been a lack of empirical studies on the impact of child routines on adjustment. A series of instruments, the Child Routines Questionnaires (CRQ) and the Adolescent Routines Questionnaires, were developed to assess routines in childhood. Recently, a self-report version of the CRQ was developed for children aged eight to 12. Initial validity estimates of the CRQ were weak, which may have been a result of cross-informant variance stemming from parent and child reports. The primary purpose of this study is to reevaluate the factorial and construct validity of the self-report CRQ with use of a single informant. The …

To identify these factors, the researcher relied on the qualitative approach of Grounded Theory as a guide to evaluate the results of the study. Nineteen students attending a traditional high school, a digital academy, or an adult education program were randomly selected from a pool of selected students who met the criteria for participation in the study. The selected students were interviewed by the researcher with questions focusing on …

"Sí Se Puede" Latino Students Can Succeed In School: A Success Case Method Study, Manuel J. Brenes

Dissertations

In public schools about one fourth of the students identify themselves as Latinos or of Hispanic origin. Unfortunately of those Latino children who began at the elementary level, only 40% of them will graduate from high school and about 11% of high school graduates will go on to postsecondary school. In order to improve these numbers, educators and policymakers cannot ignore the needs of this marginalized population.

This study focused on protective and risk factors that influence Latino student’s academic success and continuation into postsecondary school. This study furthermore explored how the Success Case Method (SCM), an evaluation technique used …
