Ranging Patterns And Habitat Utilization Of Northern River Otters, Lontra Canadensis, In Missouri: Implications For The Conservation Of A Reintroduced Species, Deborah Dorothy Boege-Tobin

Dissertations

I studied the spacing patterns and habitat utilization by reintroduced northern river otters, Lontra canadensis, at two sites in Missouri because previous studies of otters indicate, plasticity of a species social structure will likely be due to the tactics employed in acquiring resources in any given area. Seven hypotheses were tested by employing radio-tracking, habitat assessment and geographic information system approaches: (1) home range (HR) and core area (CA) size differ by sex; (2) HR and CA size differ in breeding vs. non-breeding seasons; (3) percent range overlap differs by sex; (4) habitat utilization, as indicated by latrine use, …

An Examination Of The Psychometric Properties Of The Spiritual Well-Being Scale In A Sample Of African American Women, Mary Catherine Dugan

Dissertations

This dissertation is an investigation of the psychometric properties of the Spiritual Well-Being Scale (SWBS) (Paloutzian & Ellison) using a sample of African American women recruited from the community. The purpose was to determine the appropriateness of using the SWBS with a sample not included in the earlier norming studies (Ledbetter et al., 1991). The sample consisted of 168 African American women who were parents or guardians of youth attending middle school in a Midwestern urban area. The women completed a survey including demographic information, parent scales, and the SWBS. Construct validity of the SWBS was examined by conducting a …

Student Experiences During The 1954-1955 Merger Of Harris And Stowe Teachers Colleges, Kenneth Allen Wetstein

Dissertations

This project is a historiography of the merger of Harris and Stowe Teachers Colleges following the Brown v. Board of Education U.S. 483 (USSC 1954) Supreme Court decision. In September 1954, these two racially segregated teachers colleges, both operated by the St. Louis Board of Education, were merged on the Harris Teachers College campus.

This study also involved the collection of data archived …

The Effect Of Socioeconomic Status On Year-To-Year Persistence Of First-Generation And Continuing Generation Students At Two-Year And Four-Year Institutions: Developing A Conceptual Model, Jim S. Settle

Dissertations

Estimating the persistence of first-time students from the first year to the second year of college is a growing social and financial concern for postsecondary education. Studying how socioeconomic status affects year-to-year persistence may help to identify and assist those students who had socioeconomic profiles most likely to indicate challenges to year-to-year persistence.

This study used data from the Beginning Postsecondary Students Longitudinal Study (BPS:96/98). BPS is a nationally representative survey designed to provide additional information about the patterns of educational attainment and persistence for a subset of the more than 51,000 students included in the NPSAS:96 survey. This study …

Hacks, Cracks, And Crime: An Examination Of The Subculture And Social Organization Of Computer Hackers, Thomas Jeffrey Holt

Dissertations

This dissertation examines both the subculture and social organization practices of computer hackers. The concept of normative orders (Herbert, 1998: 347) is used to explore hacker subculture in different contexts. To assess hacker social organization, I use Best and Luckenbill¿s (1994) framework of organizational sophistication as well as measures from Decker et al. (1998). The relationships between subculture, social organization, and behavior are explored as well. I collected three qualitative data sets to explore these issues, including posts from six on-line hacker discussion forums, in-depth interviews with active hackers, and field observations at the Defcon 12 hacker convention. These data …

Exploration Of Ideal Body Image Among African-American Women, Shannon Denise Nickens

Dissertations

Body image dissatisfaction is a pervasive problem, most notably among women, that is neither well understood nor well defined. Inconsistent and overly narrow definitions of body image make it difficult to draw conclusions regarding the degree and type of dissatisfaction across cultural and/or various ethnic groups. Thus far, research has largely focused on size, shape, and weight concerns, ignoring physical features that may be salient to women belonging to non-Caucasian ethnic groups. This study explored African-American (AA) preferences for weight, waist-to-hip ratio (WHR), and salient physical appearance attributes, as well as their identification with the ¿thin¿ ideal, racial identity salience, …

How High School Science-Related Experiences Influenced Career Persistence, Andrew Dwight Shaw

Dissertations

The events of 9/11 brought into focus two ongoing trends that were present before this tragedy and have continued since: 1) The United States needs more scientists if it is to ensure its freedoms and maintain its economy. 2) The number of scientists in the ¿pipeline¿ is declining because of the diminished presence of foreign scientists (they are wanted in their own countries), the under-representation of minorities and women, and the reduced numbers of students able and willing to take on the scholastic rigors necessary for a science or engineering degree. Though much has been written about improving science education, …

The researcher was a participant observer within the context of the Science, Technology & Culture: Empowering Learners (STC) program, an after-school and school-based collaboration focused upon integrating science, technology and culture. Electronic communication provided a vehicle for dialogue between youth in St. Louis, Missouri, USA and a South African Township. Study findings include documentation of the marginalizing effects of poverty …

When The Past Meets The Present: Economic And Business Development Of Hungary And Russia From Communism To Market, Zinaida Karapetyan

Dissertations

The study analyzes the continuity in economic and business development in Hungary and Russia from command economy to market. It consists of two parts.

The first part presents an overview of historical development of the planned economic system in Russia and Hungary with the emphasis on two issues ¿ how the system came about and what kind of reforms had been introduced prior to its collapse. The first issue is addressed to demonstrate that the communist regime in either country was not simply imposed on it by some ideologically driven group, in the case of Russia, or by the Soviet …

An Analysis Of Rhythm Systems In The United States: Their Development And Frequency Of Use By Teachers, Students, And Authors; And Relation To Perceived Learning Preferences, Paul Charles Varley

Dissertations

One of the issues facing music educators is the way in which they teach students to read rhythms accurately. Using the current educational philosophy of differentiation, or teaching a student by appealing to their preferred learning style, as a backdrop, the researcher proposed that music educators tend to teach rhythms using a limited number of systems, thereby failing to utilize many of the available systems.

The researcher examined the published rhythm systems dating back to the early nineteenth century, surveyed band students in grades 7-12 concerning their preferences in learning rhythms and their learning styles, surveyed music teachers concerning their …

The researcher proposes that within the context of multi-cultural American music, Alice Parker's unique approach to music making and how it is manifested within her choral compositions, arrangements, and teaching techniques is a significant and valuable area of study for music educators and students. Further, it is beneficial to administrators and the general public, as well.

Within the literature review, Alice Parker's unique and effective approach to music making is related to the need for a philosophy of music, educational …

The Role Of Embeddedness Factors In Predicting The Paths Of The Unfolding Model Of Voluntary Turnover, Lynn R. Kalnbach

Dissertations

A great deal of research has been conducted to determine the relationship between the job satisfaction of employees and the likelihood of their leaving or intending to leave an organization. However, research addressing other reasons why employees may leave their organizations has been lacking. Lee and Mitchell (1994) created the unfolding model of turnover to better define and classify the process employees go through in making decisions to leave their organizations. This model suggests that many people decide to leave their jobs/organizations for reasons other than job dissatisfaction.

In a separate stream of research, Lee and Mitchell and their colleagues …

The Role Of Puf3 Protein Interactions In The Regulation Of Mrna Decay In Yeast Saccharomyces Cerevisiae, Shervin Sean Houshmandi

Dissertations

The regulation of messenger RNA (mRNA) metabolism is an important step in proper gene expression. In many eukaryotic organisms this regulation can be mediated by a group of highly conserved RNA-binding proteins known as the Puf family of proteins. The yeast Saccharomyces cerevisiae has several proteins that belong to this family. One of the yeast Puf proteins, Puf3p, binds and regulates the COX17 mRNA, which codes for a protein involved in mitochondrial copper transport. Specifically, Puf3p stimulates the decay of COX17 mRNA. However, the precise mechanism of Puf3p binding and decay regulation is yet unknown. The goal of this research …

The Interactive Roles Of Gender And Ethnicity In African-American Women's Mental Health, Dianna Nadine Moses-Nunley

Dissertations

Abstract For African-American women, female gender and African-American (AA) ethnicity combine to create experiences of discrimination, discrimination related stress, and mental health issues that are not encountered by individuals who occupy only one of these status variables. Gender and ethnicity also influence socioeconomic status, an additional variable affecting the experiences and issues that AA women uniquely encounter. The first goal of this study was to examine the ways in which the combined social statuses of gender and ethnicity influence the discriminatory experiences and mental health of AA women. The second goal was to determine the ways in which AA women¿s …
