Parameter Importance Of An Analytical Model For Transport In The Vadose Zone, Tanner Hans Bushnell

Theses and Dissertations

The American Society of Testing and Materials (ASTM) has established a three tier risk-based corrective action (RBCA) program for cleaning up petroleum release sites, which is supported by the Environmental Protection Agency. RBCA programs make the cleanup of spill sites more efficient by requiring additional site information only when a more accurate risk assessment is needed. For spill sites that do not pass the first tier general assessment, a Tier 2 evaluation involving site specific information and screening level models to assess the potential risk must be conducted. Screening level models generally require site specific input parameters. To increase efficiency …

Predicting Group Performance Using Cohesion And Social Network Density: A Comparative Analysis, Frederick W. Peterson

Theses and Dissertations

Group performance has been an important topic as evidenced by an extensive literature review that has supports a positive relationship between group cohesion and performance. Social network researchers have also found similar relationships between cohesion and group performance using social network density as a proxy for cohesion. The traditional cohesion construct is measured using an attitudinal instrument that relies on member perceptions that are aggregated at the group level. The density construct, on the other hand, is based on social network relations which are based on behaviors and actual member interactions and relationships. Considering these differences, although both cohesion measures …

The Effects Of Social Network Centrality On Group Satisfaction, Peter M. Choi

Theses and Dissertations

The purpose of this research was to identify how various social network centralities affect a person’s satisfaction level. Simple degree centrality has been utilized to specify an individual’s location in a network by measuring the number of direct links with other members in the organization (Brass & Burkhardt, 1992, 1993). This study examines how location in friendship, task, and avoidance networks affect an individual’s satisfaction with the group. To determine the relationship between social network centrality and work group satisfaction, a longitudinal field study was conducted on 440 active duty enlisted military members in a leadership development training course. While …

Mapping Change Management: A Co-Citation Analysis, Brian R. Low

Theses and Dissertations

Today's organizations are continually undergoing changes to make improvements in their efficiency and effectiveness. The ability of organizations to effectively implement and sustain successful change, however, has been limited, with most change initiatives failing to attain the desired success. To counter this trend, researchers across several disciplines have worked to provide practitioners better insight into how to facilitate change within their organizations. This research has resulted in many theories as to what constitutes change and how best to implement it, but it lacks a unifying theory that encompasses all aspects of change research. This effort takes a step toward a …

The Chaos Of Katrina: A Nonlinear Analysis Of Federal Logistics Support During Hurricane Katrina Relief Operations, Gerald W. Morris Jr.

Theses and Dissertations

This thesis presents a case study of federal logistics support during Hurricane Katrina disaster relief operations. Data from federal contracts covering the first 10 weeks of Katrina are used to measure federal logistics activity. The study investigates whether chaos theory, part of complexity science, can extract information from Katrina contracting data to help managers make better logistics decisions during disaster relief operations. The study uses three analytical techniques: embedding, fitting the data to a logistic equation, and plotting the limit-cycle. Embedding and fitting a logistic equation to the data were used to test for deterministic chaos. The logistic equation and …

Examining Clandestine Social Networks For The Presence Of Non-Random Structure, Joshua S. Seder

Theses and Dissertations

This thesis develops a tractable, statistically sound hypothesis testing framework for the detection, characterization, and estimation of non-random structure in clandestine social networks. Network structure is studied via an observed adjacency matrix, which is assumed to be subject to sampling variability. The vertex set of the network is partitioned into k mutually exclusive and collectively exhaustive subsets, based on available exogenous nodal attribute information. The proposed hypothesis testing framework is employed to statistically quantify a given partition's relativity in explaining the variability in the observed adjacency matrix relative to what can be explained by chance. As a result, valuable insight …

The Tragic Consequences Of Societal And Cultural Memory: William Shakespeare And Arthur Miller, Leslie A. Werden

Theses and Dissertations

This dissertation argues that tragedy occurs not to a great man or a common man, but to the family left behind to confront the societal and cultural implications of the manipulated memories they have inherited. Using Chris Hedge's book War is a Force that Gives Us Meaning, I investigate how storytelling and legacy are passed along to family members who have been affected by war. Shakespeare's Titus Andronicus and Miller's All My Sons suddenly seem very similar: both plays have fathers who lost sons, which is tragic in itself. The deeper psychological tragedy occurs, however, as the fathers, in order …

Campus Racial Climate As Perceived By Undergraduate American Indian Students Attending The University Of North Dakota, Cynthia A. Lindquist Mala

Theses and Dissertations

Enriched and enhanced learning environments are created by a diverse campus population that allows for an increased understanding, acceptance, and/or tolerance of cultures different from one's own. Higher education institutions are in unique positions to address the teaching and learning of diversity by creating environments that allow for positive interactions among all people. Campus racial climate has been identified as a critical factor in the success and/or failure of minority students. Of the 42,500 college students in North Dakota, approximately 4,200 are minority students. The American Indian population in North Dakota is approximately 5% of the state's population and about …

An Analysis Of The Subjective Socioeconomic Scale Among Hispanic Immigrants And Caucasians, Mathew Glen Bowden

Theses and Dissertations

Subjective socioeconomic status (SES) has previously been shown to be correlated with a large number of health measures. In this study, the subjective SES measure is modified and translated to measure childhood SES. The subjective SES scale is examined in a participant's hometown, community, and nation. Both an immigrant Hispanic and a Caucasian sample were studied (31 Hispanic males; 42 Hispanic females; 38 Caucasian males, 40 Caucasians females). Childhood SES was the most significant predictor of self-reported health in both sample groups.

Implicit Affinity Networks, Matthew Scott Smith

Theses and Dissertations

Although they clearly exist, affinities among individuals are not all easily identified. Yet, they offer unique opportunities to discover new social networks, strengthen ties among individuals, and provide recommendations. We propose the idea of Implicit Affinity Networks (IANs) to build, visualize, and track affinities among groups of individuals. IANs are simple, interactive graphical representations that users may navigate to uncover interesting patterns. This thesis describes a system supporting the construction of IANs and evaluates it in the context of family history and online communities.

Is Marriage Education Effective? A Meta-Analytic Review Of Marriage Education Programs, Elizabeth Brinton Fawcett

Theses and Dissertations

In the past few decades, several meta-analytic studies have attempted to answer the question: Is marriage education effective (Carroll & Doherty, 2003; Halford, Markman, Kline & Stanley, 2003; Reardon-Anderson, Stagner, Macomber, & Murray, 2004)? However, previous meta-analytic studies have been somewhat limited in their conclusions because they have reviewed a narrow portion of the marriage education spectrum (e.g. premarital education only, Carroll & Doherty, 2003), because they focused only on one particular program (e.g, Couples Communication, Butler & Wampler, 1999), because they failed to differentiate marital therapy from marital education programs (Reardon-Anderson et al., 2005), or because they excluded much …

Sociocultural Strain Theory, Amy L. Proctor

Theses and Dissertations

In reaction to criticisms of existing strain theories, Agnew (1992) developed General Strain Theory, and in doing so moved toward micro-level conceptions of strain. A return to the cultural concepts found in traditional strain theories may provide a more complete examination of delinquency/criminality, as it would incorporate the influence that culture has on rates of delinquency/criminality among certain groups in American society. This thesis adds to the knowledge base of criminological thought through the creation of a new strain theory. Sociocultural Strain Theory (SST) may provide a better explanation of delinquency/criminality, particularly among racial/ethnic minorities, by taking into consideration cultural …

Determinants Of College Students' Opinions Towards Felon Voting Rights: An Exploratory Study, Edwards Brenda Cherie Dawson

Theses and Dissertations

The disenfranchisement of felons follows a long American tradition of selectively granting the most coveted democratic tradition - voting. As a collateral "civil" consequence to criminal conviction that is legally deemed as non-penal, felon voting prohibitions have been used as an exclusionary tool for certain otherwise eligible voting populations. Current research finds that African-Americans individually and collectively may experience diminished voting power due to felon voting laws (Uggen & Manza, 2002; Manza & Uggen, 2004; King & Mauer, 2004). The purpose of this research is to examine opinions toward felon voting prohibitions in a state that has one of the …

Alternative School Administrators And Teachers Perception Of Effective School Correlates In The Organizational Culture And Operation Of Alternative Schools, C.W. Gardenhire

Theses and Dissertations

The purpose of the study was to examine whether alternative schools incorporate effective school correlates in their organizational culture and operation as these same elements are typically identified in the traditional effective school research. A quantitative descriptive study method was selected to conduct the study. The sample consisted of administrators and teachers actively involved in alternative schools. Further the sample was geographically located in the Mid-South, specifically Arkansas, East Texas, Northern Louisiana, North West Mississippi, and Western Tennessee. The study concluded that effective school correlates — clear school mission, frequent monitoring of students, and instructional leadership — were perceived to …

Characteristics And Offending Patterns Of Juvenile Female Sex Offenders, Antonela Tomic

Theses and Dissertations

Although there has been an increasing interest in juvenile female sex offenders, existing research is limited. This thesis examines the demographic characteristics of juvenile female sex offenders, their victims, and their offense characteristics using a national sample of 172 juvenile female sex offenders who were arrested for sex offenses in 2001. The typical offender was a 14-year-old white female and was arrested for forcible fondling. The majority of the victims were white females who knew their offenders. Most of the offenses were committed at a residence. The use of force, as well as use of alcohol and/or drugs at the …

Vocational Rehabilitation Of Clients With Brain Injury: An Investigation Of Racial Disparity Within The Rehabilitation Services Administration (Rsa) 911 Database, Stephanie A. Kolakowsky-Hayner

Theses and Dissertations

Finding and maintaining employment is an ongoing problem for persons with disabilities, especially those with brain injuries. State vocational rehabilitation agencies are the primary authority responsible for providing employment-related services for individuals with disabilities throughout the United States. Little effort has been committed to identifying disparities in health and rehabilitation services provided to Americans with disabilities, particularly those with brain injuries. The purpose of this investigation was to utilize Aday and Andersen's Framework for the Study of Access to examine racial disparity within the Rehabilitation Services Administration 911 Database, and thus the vocational rehabilitation system, among clients with brain injury. …

The Effects Of Concerted Cultivation On Academic Achievement, Jeremy Brandon Redford

Theses and Dissertations

Anne Lareau (2003) argues that parents' child-rearing practices have a profound effect on academic and later occupational success for children, even holding constant such important factors as gender, race and school effects. She says that social class impacts these child-rearing practices and that middle-class families use a specific type of practice called concerted cultivation. Concerted cultivation involves parents organizing children's daily activities, using reasoning skills in talking with children, and teaching them how to interact with the institutions around them. Using the National Education Longitudinal Study (NELS) of 1988, the current study tests the theoretical validity of concerted cultivation. Results …

The population of the United States is increasingly gaining weight each year.Americans are heavier than they have ever been. African American women are at the forefront of this pandemic. This study addresses the higher prevalence of overweight and obesity among African American women in comparison to White women. Behavioral, psychological, and social known contributors to overweight and obesity using the National Health Interview Survey, 2001 dataset were examined in this study. The research concluded that even when controlling for vigorous exercise, education, income, depression, emotional support, smoking, health coverage, and age, race is the most important predictor of body mass …

"Shut It Down, Open It Up": A History Of The New Left At The University Of Virginia, Charlottesville, Thomas M. Hanna

Theses and Dissertations

This thesis is a history of social and political activism in Charlottesville during the 1960s focusing on new left student organizing at the University of Virginia. It is a work of social history that establishes a community that has been generally ignored in traditional histories of the new left as one of the most influential centers of new left activism in the South and asserts that this prominence was due to years of activism by local liberals, civil rights advocates, and students during the city's unique experiences on the front lines of the southern desegregation, civil rights, and anti-war struggles. …

Constraints On Breastfeeding Choices For Low Income Mothers, Carol Grace Hurst

Theses and Dissertations

The choice to breastfeed a baby is a woman's concern with impact reaching beyond each individual mother and child to longer term health and mental health outcomes for society. The U.S. government has made increasing breastfeeding rates one of its major public health goals for 2010. Breastfeeding is a health disparity issue with mothers who are poor, young, less educated or Black less likely to breastfeed. This project examined impacts of sexual perceptions of breastfeeding, social support, and work on breastfeeding choices made by a sample of low income mothers. A cross-sectional survey design was employed to examine potential barriers …

Roles And Attitudes Of Males And Females In The Anarchist Punk Community, Donna M. Manion

Theses and Dissertations

Sexism is a widespread social problem that exists throughout the world today. It persists within the dominant culture, as well as in various subcultures, including the punk subculture (Daugherty 2002; Leblanc 1999; McRobbie 1991; Rosenberg and Garofalo 1998). Nijole Benokraitis and Joe Feagin's (1995) theory of sexism posits that subtle sexism is the unequal and harmful treatment of women that is typically less visible than blatant sex discrimination. This particular type of sexism may often go unnoticed, as society has internalized subtle sexist behaviors. Empirical research on subtle sexism has been conducted in various settings, such as the employment, academic, …

Pedagogical Fusion, David Maurice White

Theses and Dissertations

During the five semesters that I have been at VCU I have learned a great deal from the courses that I have been enrolled in but I have learned the most through my experiences as a Teaching Assistant. These experiences have been so valuable because of the wide range of subject areas in which I have been involved and the diverse instructors that I have assisted. Although I hesitate to use the word "problem" I feel that there is a tendency in teacher training for a student to latch onto one professor and model their teaching practices after that one …

A Life In Words, Thoughts, Ideas, Images And Movement, Randy Houston Mercer

Theses and Dissertations

I know it is my core, my purest nature to incessantly question myself and everything around me; as we pertain to the universe. As Robert Wilson suggests "I will always ask 'What is it?' before telling you what it is." My goal is to present you with some tools with which to approach your craft, your life, your uncertainties. And though I may not always be the best example, I still wish to encourage all that read this or spend time with me to see this craft/business and indeed your life as a great, happy adventure; guided by love. Because …
