Measures were assessed the summer prior to kindergarten, within two weeks, and after a month of the transition to kindergarten. The study revealed that the transition to kindergarten was associated with changes in sleep and dietary intake. Endocrine function remained stable as children transitioned to kindergarten. On average, Nap and Non-Nap Groups equally lost total sleep time as they transitioned to kindergarten. However, the …

Bullying And Gender: The Social/Emotional, Psychological, And Physical Effects On Middle School Students In South Mississippi, Cassundra Peyton-Brown

Dissertations

Bullying is a great concern in schools today. When bullying occurs, it hinders school success and academic performance. During the late 1980s and 1990s, school violence was prevalent in middle school characterized by events such as the Columbine shooting. This forced both students and school personnel to deal with school shootings, gang activities and other violent acts. According to subsequent investigations, some of these incidents occurred because students were bullied and teased. This supports the maxim that students can only be successful academically in a safe and orderly environment.

The first interest of this study was to assess the effects …

Increasing Readiness To Change Anger: A Motivational Group Intervention, Gregory Lee Futral

Dissertations

The conceptualization and treatment of problematic anger has received increased attention in the literature in recent years. Among the challenges in working with persons experiencing anger-related difficulties, barriers in forming the therapeutic alliance (Tafrate & Kassinove, 2003), resistance behaviors (DiGiuseppe, 1995), and/or low motivation to change (DiGiuseppe & Tafrate, 2007) have been commonly identified as having the potential to derail the treatment process. Strategies developed to increase treatment motivation and readiness to change, such as those found in the literature on the transtheoretical model (TTM; Prochaska & DiClemente, 1982) and motivational interviewing (MI; Miller & Rollnick, 2002), have been proposed …

If And To What Extent Spirituality Impacts The Leadership Practices Of Four African American Superintendents, Christopher James Williams Sr.

Dissertations

Public school superintendents have one of the most challenging, demanding, and visible positions in American society. They provide educational leadership in approximately 15,499 school districts across the United States. Their visibility is marked by the fact that the majority of leadership positions are held by non-minority individuals (American Association of School Administrators, 1992). The underrepresentation of minorities in public school leadership positions on a national level has been thoroughly documented over the years, and the limited representation of African Americans in top positions of public school administration is glaring (AASA, 1992, 1983; Jones & Montenegro, 1988, 1985; Montenegro, 1993). The …

Differentiating Classes From Dimensions Under Unfavorable Data Conditions: Monte Carlo Comparisons Of Taxometric And Latent Variable Mixture Models, Anthony Olufemi Ahmed

Dissertations

Taxometric and latent variable mixture models can aid in (1) determining whether the source of population heterogeneity, a latent variable, θ, is best explain by a dimensional (one-class) or taxonic (two-class) model and (2) distinguishing between constructs continuously distributed and those that are Bernoulli distributed at the latent level. Although these models have gained widespread use in psychology research, few have been systematically evaluated to determine the robustness of their results when statistical assumptions are violated (e.g., severe skew, unequal mixing proportions, etc.). The current study examined the performance of Meehl’s taxometric procedures and two latent variable mixture models: a …

Tongueless: Representation Of The Mentally Disabled And The Novel, Brent Walter Cline

Dissertations

This study examines the representation of the mentally disabled in the novel for two related outcomes. The first is to prove that the representation of the mentally disabled is not merely a subset of the representation of the disabled in general. This is intended less as a political statement as it is a literary one. Acknowledging and building off the work of writers in disability studies such as David Mitchell, Sharon Snyder, and Tobin Siebers who concentrate on the body of the disabled, this study shows that attempts to represent the mentally disabled are fundamentally different than those who are …

Lgb-Affirmative Therapists' Use Of Developmental Models Of Lgb-Identity In Therapy. A Phenomenological Investigation, Victoria E. Cane

Dissertations

Socially sanctioned hostility toward sexual minority persons continues to be a reality in the United States and worldwide. Therapists working with sexual minorities have responsibility to provide non-pathologizing, affirmative therapy to these clients. A central aspect of affirmative therapy is therapists' recognition and understanding of sexual orientation (SO) identity and developmental models of sexual minority identity have a played a vital role in promoting this understanding. Although such models have been central to the practice and training of affirmative therapy, therapists' applied use of the models has not been empirically investigated. For this phenomenological study, nine affirmative therapists were interviewed …

Gold Nanoparticle - Modified Zinc Oxide Nanoparticles As Novel Photocatalytic Materials, Nayane Udawatte

The Nature Of The O-2/O-5 Cooperative Effect And Its Role In Chemical Glycosylation, Laurel Kathryn Mydock

Dissertations

Since carbohydrates were first discovered, understanding the structure, reactivity, and function of these bioorganic compounds has remained of great priority. However, as the appreciation for the biological roles of carbohydrates intensifies, a growing demand for efficient and scalable methods towards the synthesis of these challenging molecules has become even more imperative. While modern synthetic techniques have allowed us to readily achieve most glycosidic linkages, it is the inability to effectively predict and control the stereoselectivity of the glycosylation reaction that has remained the synthetic hurdle. Herein, much effort has been placed in the investigation of “mixed-patterned” glycosyl donors as they …

The goal of this dissertation – A Guide to Drug Dealing – is to move scientists toward a deeper conceptual and theoretical understanding of illicit drug markets. What behaviors are experienced in the course of drug dealing? Why do some customers get a better price than others? What are the circumstances that result in retaliation? Why do some victimized drug dealers respond with peaceful social control rather than violence? What leads to the termination of drug dealing? When does the law handle drug market conflict? In short, this is a guide to drug dealing that – chapter by chapter – …

Educating For The Knowledge Age: A Collective Case Study Of Teachers’ Beliefs In A Problem Based Learning Environment, Amy Marie Ruffus Doerr

Dissertations

There is a growing trend in the business literature; education is not preparing students for the Knowledge Age. The literature further states the foundation of a successful Knowledge Economy and the production of its knowledge workers is education. Considering that the school system is a foundation for learning, it is a startling revelation that education reform has not focused more explicitly on knowledge work. If we expect to be successful in the Knowledge Age, a new conception of knowledge and learning is necessary, and will aid in the development of new knowledge workers. This further necessitates a more in depth …

Constitutive Modeling Of Glassy Memory Polymers, Mahesh Khanolkar

Dissertations

The aim of this research is to develop constitutive models for non-linear materials. Here, issues related for developing constitutive model for glassy shape memory polymers are addressed in detail. Shape memory polymers are novel material that can be easily formed into complex shapes, retaining memory of their original shape even after undergoing large deformations. The temporary shape is stable and return to the original shape is triggered by a suitable mechanism such heating the polymer above a transition temperature. Glassy shape memory polymers are called glassy because the temporary shape is fixed by the formation of a glassy solid, while …

Modeling With Bivariate Geometric Distributions, Jing Li

Dissertations

This dissertation studied systems with several components which were subject to different types of failures. Systems with two components having frequency counts in the domain of positive integers, and the survival time of each component following geometric or mixture geometric distribution can be classified into this category. Examples of such systems include twin engines of an airplane and the paired organs in a human body. It was found that such a system, using conditional arguments, can be characterized as multivariate geometric distributions. It was proved that these characterizations of the geometric models can be achieved using conditional probabilities, conditional failure …

Experiences Of Pregnancy, Childbirth And Post-Partem Period In Urban And Suburban Immigrant Pakistani Women, Rubab I. Qureshi

Dissertations

A body of research suggests that immigrants arrive in the U.S. in good health, a healthy immigrant effect. As immigrants acculturate and absorb dominant cultural norms (measured by proxy variables such as language preference, employment, smoking and alcohol consumption), their health status deteriorates. There is a need to understand how immigrants adapt to a changed social and cultural environment and how this may influence health.

A study of pregnancy, childbirth and the postpartum period in immigrant Pakistani women living in New Jersey explored the interface of culture, immigration and health. The study employed a three pronged approach. Census data were …

Individuals Differences In Exploratory Behavior Of Prairie Voles, Microtus Ochrogaster, Danielle N. Lee

Dissertations

Individual differences in behavior are significant because they serve as the substrate for natural selection. Within the Behavioral Syndromes framework, researchers study individual differences in behavior of animals. Behavioral Syndromes are defined as correlations between behaviors in different environmental contexts or testing situations. In this study, I examined the effects of litter size and sex ratio, familial relationships, and age and sex on exploratory behavior of prairie voles, Microtus ochrogaster. Exploratory behavior, defined as spontaneous behavioral responses to unfamiliar stimuli, was examined in three novel situations: an open-field with novel objects, a two-way novel choice apparatus, and a complex maze. …

Effect Of Anions On The Iron Release Pathways Of Human Serum Transferrin, Rashmi Subhash Chander Sharma

Dissertations

Transferrin, the serum iron transport protein in humans, is used to transport 30-40 mg of iron per day through blood. The accessibility of transferrin makes it an attractive target for iron cheating therapeutic agents used in the treatment of iron overload. There is an ongoing search for ligands which can accelerate the rate of iron release, as the currently approved drug DFO has a very slow rate for iron removal. Previous studies have shown that anions can accelerate the rate of iron release. Studies on the effect of anions on the rates of iron release from C-terminal monoferric transferrin at …

"It's No Secret": The Experiences Of Eight Lesbian Public School Administrators With District Personnel, Students And Their Parents, Kelly Marie Grigsby

Dissertations

“…These questions are always hard to answer because when you’re living gay, you don’t know which decisions you’re making because you’re gay or because you’re living” (Adrian 596 – 598). The purpose of this phenomenological study was to explore the ways lesbian school administrators in K-12 public schools answer questions about their sexuality from students and their parents and how their feelings, experiences and this partial or potential closet affect their leadership. I completed a series of three in depth interviews with eight European American school administrators that identify as lesbian. I begin by sharing a snapshot of the participants’ …
