The Establishment of Norms for Two Selected Tennis Skills Tests at North Texas State University

Description: The purposes of this study were 1) to establish validity and reliability for a modified service test, 2) to determine male and female norms for the service test, and 3) to establish norms for the Kemp-Vincent Rally Test. Subjects were 677 students enrolled in beginning and intermediate tennis classes at North Texas State University, Denton, Texas. Data were analyzed by the two-way analysis of variance to establish reliability. Norms were established by converting raw scores to normalized standard T-scores. Conclusions of the investigation were 1) the modified service test is valid and reliable, and 2) there is a need for separate male and female norms when the skill is governed by strength.

Estimated Extent and Fate of Chlorinated Solvent Contamination in the Soil of the Naval Air Station, Dallas, Texas

Description: This thesis estimates the spatial extent of chlorinated solvent contamination of the soil at the Naval Air Station, Dallas, then estimates the fate and transport of these contaminants, over time, using the Soil Transport and Fate database and the Vadose-Zone Interactive Processes (VIP) modeling software. Geostatistical analysis identifies two areas with serious chlorinated solvent contamination. Fate and transport modeling estimates that this contamination will degrade and disperse from the soil phase to below regulatory limits within one year, although there is a risk of groundwater contamination. Contaminants are estimated to persist in the water and air phases of the soil. Further sampling is recommended to confirm the results of this study.

Estimating Buruli Ulcer Prevalence in Southwestern Ghana

Description: Mycobacterium ulcerans is sweeping across sub-Saharan Africa, but little is known about the mode of transmission and its natural reservoirs. Since the only effective treatment is excision of the infection and surrounding tissue, early diagnosis and treatment is the only way to reduce the havoc associated with Buruli ulcer. Using data from a national case search survey conducted in Ghana during 2000 and suspected risk factors this study tests the hypothesized factors and probes the challenges of developing a spatial epidemiological regression model to explain Buruli ulcer prevalence in the southwestern region of Ghana representing 42 districts. Results suggest that prevalence is directly related to the degree of land cover classified as soil, elevation differential, and percent rural population of the area.

Estimation of Air Emissions During Production Phase from Active Oil and Gas Wells in the Barnett Shale Basin: 2010-2013

Description: The Barnett shale basin, the largest onshore gas field in the state of Texas, mainly produces natural gas. The basin’s oil and gas productions have dramatically increased over the past two decades with the enhancement via shale fracturing (fracking) technology. However, recent studies suggest that air emissions from shale fracking have significantly contributed to the growing air pollution problem in North Texas. In this study, air emissions from the Barnett shale basin during the production phase of the oil and gas activities (once the product is collected from the wells) are quantified. Oil and gas production data were acquired from the Texas Railroad Commission for the baseline years of 2010 through 2013. Methodology from prior studies on shale basins approved by the Texas Commission on Environmental Quality was employed in this study and the emission inventories from the production phase sources were quantified. Accordingly, the counties with the most gas operations in the basin, Tarrant, Johnson, Denton and Wise, were found to be the highest emitters of air pollutants. Tarrant County was responsible for the highest emitted NOx (42,566 tons) and CO (17,698 tons) in the basin, while Montague County released the maximum VOC emissions (87,601 tons) during the study period. Amongst the concerned emitted pollutants, VOC was the largest emitted pollutant during the study period (417,804 tons), followed by NOx (126,691 tons) and CO (47,884 tons). Significant Sources of air emissions include: storage tanks, wellhead compressor engines, and pneumatic devices. Storage tanks and pneumatic devices contributed to about 62% and 28% of the total VOC emissions, respectively. Whereas, wellhead compressor engines are primarily responsible for about 97% of the total NOx emissions. Finally, in Tarrant, Wise and Denton counties, the emissions increased during the study period due to increase in the oil and gas production, while Johnson County’s emission ...

Estimation of Aircraft Emissions for the Corpus Christi International Airport, Corpus Christi, Texas

Description: Commercial aviation is a vital part of the United States economy. It generates over $1 trillion annually, which is more than 5% of the U.S. GDP, and produces approximately 10 million jobs. Every year there is an increase in commercial air traffic. This is attributed to expanding trade between states and other countries, which requires larger amounts of cargo aircraft in operation, and also catering to the growing number of middle and upper class passengers who travel for business and pleasure purposes. A rise in commercial aviation leads to the use of more aviation fuel on a monthly and annual basis. This in turn leads to escalated levels of combustion by-products from jet and turbofan engines into the atmosphere. The negative effects of these by-products range from producing poor air quality and consequent health hazards to contributing to global warming. This study is aimed at assessing the impacts of aircraft emissions on the local air quality in Corpus Christi using the Emissions and Dispersion Modeling System. Flight data for the study was obtained from the Department of Transportation's Research and Innovative Technology Administration. Analyses of the emissions were compared on monthly, annual, engine type and airline provider bases. Climatic, economic and anthropogenic factors were identified in the analyses.

Ethical Decision Making in the Indian Mediascape: Reporters and Their Stories

Description: Hundreds of reporters gather and interpret news for four English-language newspapers in India's second-largest urban area Kolkata, West Bengal's state capital, which is home to over 4 million people. Journalists from The Statesman, The Telegraph-Kolkata, The Hindustan Times and The Times of India discuss how they collect their stories in Bengali, Hindi, Urdu, and many other languages and write them in English targeting a small but emerging middle-class audience. Whether these articles focus on people-centric urban planning, armed vigilantes in community disputes, dowry death cases, or celebrity culture, all of the reporting involves cultural and ethical challenges. Using semi-structured interviewing and qualitative theme analysis, this study explores how gender, class, and religion affect the decision-making practices of 21 journalists working in Kolkata.

Ethical Reasoning Among Baccalaureate Female Nursing Students

Description: The focus for this study was ethical reasoning among baccalaureate female nursing students. This descriptive and correlational study examined the ethical reasoning of freshmen and senior students at a large southwestern university for women. The research instrument used was the Defining Issues Test developed by Rest. The senior nursing students differed significantly (p < ,05) from the freshmen nursing students in ethical reasoning. However, nursing majors did not differ significantly from the non-nursing majors. A multiple regression analysis was performed that identified two factors associated with ethical reasoning (viz., age and GPA), The correlation coefficients were r= .377 for age and P_ score and r= .315 for GPA and P score. Older students were found to be significantly more advanced in ethical reasoning than were younger students. Students with higher GPAs used principled reasoning significantly more often than did students with lower GPAs. Of interest are the findings related to demographic characteristics, ethnicity, and religious preference. The sample was predominantly white, but a significant difference in use of principled reasoning between whites and non-whites was found. In the sample, whites used ethical reasoning more often than did non-whites. The students in the sample who labeled themselves as Baptists were significantly different from Traditional Christians (Methodists, Episcopalians, Presbyterians, Lutherans, and members of the Church of Christ) and Other Christians (all others, excluding Baptists, Catholics, and the Traditional Christians). The Baptist group used principled reasoning less often than did the other two groups of Christians. The Catholics were not significantly different from the Baptist, Traditional Christian, or Other Christian groups. The results are ambiguous and may reflect only a conservative philosophy or a conservative theological ideology rather than cognitive processing.

Ethics in Technical Communication: Historical Context for the Human Radiation Experiments

Description: To illustrate the intersection of ethical language and ethical frameworks within technical communication, this dissertation analyzes the history and documentation of the human radiation experiments of the 1940s through the 1970s. Research propositions included clarifying the link between medical documentation and technical communication by reviewing the literature that links the two disciplines from the ancient period to the present; establishing an appropriate historiography for the human radiation experiments by providing a context of the military, political, medical, and rhetorical milieu of the 1940s to the 1970s; closely examining and analyzing actual human radiation experiment documentation, including proposals, letters, memos, and consent forms, looking for established rhetorical constructions that indicate a document adheres to or diverts from specific ethical frameworks; and suggesting the importance of the human radiation documents for studying ethics in technical communication. Close rhetorical analysis of the documents included with this project reveals consistent patterns of metadiscourse, passive and nominal writing styles, and other rhetorical constructions, including negative language, redundancies, hedges, and intensifiers, that could lead a reader to misunderstand the writer's original ethical purpose. Ultimately this project finds that technical communicators cannot classify language itself as ethical or unethical; the language is simply the framework with which the experimenters construct their arguments and communicate their work. Technical communicators can, however, consider the ethical nature of behavior according to specific ethical frameworks and determine whether language contributes to the behavior.

Ethics Naturally: An Environmental Ethic Based on Naturalness

Description: In this thesis I attempt to base an environmental ethic on a quality called naturalness. I examine it in terms of quantification, namely, as to whether it can quantified? I then apply the concept to specific areas such as restoration and conservation to create an environmental ethic and to show how such an ethic would be beneficial in general, and especially to policy issues concerning the environment. The thesis consists of three chapters: (1) the definition of nature and natural by way of a historical approach; (2) the place of humans in this scheme; and (3) the place of value and the discussion concerning quantification.

Ethics of Teaching: Beliefs and Behaviors of Community College Faculty

Description: This study examines the ethical beliefs and behaviors of full-time community college faculty. Respondents report to what degree they practice sixty-two behaviors as teachers and whether they believe the behaviors to be ethical. Survey participants engaged in few of the behaviors, and only reported two actions as ethical: (1) accepting inexpensive gifts from students and (2) teaching values or ethics. The participants reported diverse responses to questions about behavior of a sexual nature, but most agreed that sexual relationships with students or colleagues at the same, higher or lower rank were unethical. Additional findings relate to the presence of diversity among the faculty, using school resources to publish textbooks and external publications, selling goods to students, and an expansive list of other behaviors. Findings of this study are compared to results from earlier studies that utilized the same or similar survey instrument with teaching faculty. The study has implications for organizational policy and procedure, for faculty training and development, the teaching of ethics or values in the classroom and for future research.

Ethnic Differences in Caregiving Style

Description: This study explored the caregiving styles of 306 grandparents raising grandchild across three ethnic groups (164 European Americans, 65 Latinos, and 77 African Americans). Significant differences were found in caregiving styles between European Americans and African Americans. Caregiver appraisal (burden, satisfaction, and Mastery) was found to be predictive of caregiving style across the entire sample, and differentially by ethnic group. Caregiver style was predictive of grandchild functioning across the entire sample, and differentially by ethnic group. Lastly, caregiver style was found to be predictive of grandparent well-being across the entire sample, and differentially by ethnic group. Implications are discussed in terms of the complex, multidimensional and culturally embedded nature of the caregiving experience and the importance of considering culture for optimal outcomes.

Ethnic Identity : An Examination of Hispanic International Students

Description: I interviewed twenty-four International students from the following countries: Mexico, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Peru, Colombia, Brazil, Puerto Rico and Spain. Hereafter I shall refer to the respondents as Hispanic International students. My primary interest was to learn the way in which Hispanic International students defined themselves in view of ethnic definitions imposed on them by the administrative system in the U.S. First, Hispanic International students defined themselves primarily by their nationality. The second finding dealt with the usage of language. The Hispanic International students spoke Spanish with relatives and friends. They spoke English when a non-Spanish speaker joined the conversation. The third finding was related to the problems and adaptations encountered by Hispanic International students.

Ethnic Identity, Gay Identity and Sexual Sensation Seeking: HIV Risk-taking Predictors Among Men of Color Who Have Sex with Men

Description: This study examined relationships among ethnic identity, gay identity, sexual sensation seeking, and HIV risk-taking behaviors among 302 men of color recruited from gay bars, bathhouses, community agencies, and the 1998 United States Conference on AIDS. The sample included 24% African American, 28% Latino, 25% Asian/ Pacific Islander, 19% Caucasian, 1% American Indian, and 3% other ethnicity. Logistic regression analysis identified sexual sensation seeking, having an undefined gay identity, being in a sexually exclusive relationship, not being HIV seronegative, and length of stay in the country (for those born overseas) as significant predictors of unprotected anal intercourse (insertive and penetrative) among men of color who have sex with men.

Ethnic Identity of Mexican American Children in the Post Industrial Age

Description: Ethnic identity of Mexican American children under the current socio-political climate was studied. Mexican American children were expected to display symptoms of ethnic ambivalence and self-rejection. Using the Kenneth and Mamie Clark (1947) Brown doll/White doll experiment as a model, data were gathered using a mixed model. This approach combed features of experimental designs, survey research, and qualitative methods. Both quantitative and qualitative data were gathered from a purposive sample of 104 children and some of their parents. They were between the ages of 3 to 15, resided in northeastern Texas, and most were White (n=70) or Hispanics (mostly Mexican American) (n=21) the remainder being Asian (n=13). Children self-identified across ethnic lines, and treated play preference, self-identification, and attractiveness separately. Children did not reflect social stereotypes and society's hierarchy. Instead, they portrayed other ethnic groups positively. Current theoretical approaches provided argue that strong ethnic identification and cultural incorporation displayed by the children may be a result of better integration and assimilation; conversely, it may be a product of the “false consciousness” driven by a global market and the culture of individualistic consumerism. An alternative theoretical perspective argues that the apparent cultural incorporation of children was a result of the social cultural evolution of race and ethnic relations in America. Children in this study were merely showing the next stage of the evolution explaining why Mexican American ethnic identity remained strong amidst the current socio-political climate. Implications and suggestions suggest that educators and policy makers should remain vigilant in promoting and facilitating multicultural programs in schools. Parents should play a role in promoting ethnic pride and appreciation of other cultures in order to ensure cultural incorporation. It is important for the social scientist to remain vigilant on the topic and not lose focus under the guise of greater assimilation between minorities ...

Ethnic Minorities and Prohibition in Texas, 1887 to 1919

Description: Historians of the prohibition movement in Texas have assumed that the state's main ethnic minorities-Germans, Mexican Americans and African Americans-strongly opposed restrictions on the production, sale, and transportation of alcoholic beverages. This study focuses on the voting patterns in fifteen counties chosen to represent varying percentages of these ethnic minorities in their populations during three statewide anti-alcohol elections (1997, 1911, and 1919) in an effort to determine exactly the extent of opposition to prohibition on the part of ethnic minorities in Texas. It also examines the actions of the prohibitionists and anti-prohibitionists in courting the vote of ethnic minority groups. This analysis and comparison of election results in fifteen counties confirms overwhelming opposition to prohibition on the part of all three of Texas's ethnic minorities.

Ethnic Politics in New States: Russian and Serbian Minorities After Secession

Description: New states are often born in a volatile environment, in which the survival of the new country is uncertain. While analysis of the nationalizing new governments exists, research focuses mainly on domestic politics. I argue that the treatment of minority that remains in the new states is a function of the interaction of the dual threat posed by the minority itself domestically on one hand and the international threat coming from the mother state to protect its kin abroad on the other hand. Specifically, I argue that there is a curvilinear relationship between domestic and international threat and the extent of discrimination against the politically relevant minority. Most discrimination takes place when domestic and international threats are moderate because in this case there is a balance of power between the government, the minority, and the rump state. With time-series-cross-sectional (TSCS) data analysis this dissertation systematically tests the treatment of Russian and Serbian minorities in all post-Soviet and post-Yugoslav states between 1991 and 2006 and finds statistically significant results for the curvilinear hypothesis. Territorial concentration of the minority and the ratio of national capabilities between the mother and the seceded states prove to be especially important predictors of minority treatment. In addition, with most similar systems (MSS), most different systems (MDS) design methods, and directed case studies I apply the curvilinear hypothesis to the Russian minority in the Baltic States and the Central Asian Republics, and also to the Serb minority in the countries of the former Yugoslavia to present a detailed analysis.

Ethnic Similarity and Rivalry Relations

Description: Research on ethnicity and conflict treats the concept of ethnicity as defining the actors in these conflicts, whereas research on the construction and maintenance of ethnic identity explores why ethnicity unifies individuals into a single social group. What happens when this unifying concept is divided between two enemy countries? How does this situation influence peace settlements over territorial issues, armed conflict, and economic relations between these countries? To answer these questions, I create a continuous measure of ethnic similarity between rivals. I find that ethnic similarity can facilitate cooperation and exacerbate conflictual interactions between rivals, but governments will seek to limit interactions with their rival when the cross border ethnic groups are minorities. In addition, I create categorical predictors of ethnic similarity, which reveal nuances in these relationships. Specifically, rivalries sharing a pan-ethnic identity are more likely to engage in conflict regardless of actual ethnic similarity, and dyads with a majority in one country sharing ethnicity with a minority in another country are less likely to fight once in a state of rivalry. This is because a quid pro quo exists between these rivals where one rival can reduce oppression of the minority in exchange for the other rival not supporting secessions by their co-ethnics. These pairs of rivals also are more likely to attempt peace settlements. Contested nations, which are rivalry-dyads with similar ethnic majorities, are both the most likely of the ethnically similar rival categories to engage in militarized interstate disputes, but also engage in larger amounts of interstate trade.

Ethnically Mixed Individuals: Cultural Homelessness or Multicultural Integration?

Description: Studies addressing racial/ethnic identity development have often overlooked the developmental cultural context. The impact of growing up with contradictory cultures has not been well explored. Immersion in multiple cultures may produce mixed patterns of strengths deficits. This study reviews the literature's currently inconsistent usage of the terms race, ethnicity, and culture; introduces the concept and theoretical framework of Cultural Homelessness; relates CH to multicultural integration; and develops two study-specific measures (included) to examine the construct validity of CH. The sample’s (N = 448, 67% women) racial, ethnic, and cultural mixture was coded back three generations using complex coding criteria. Empirical findings supported the CH-specific pattern of cognitive and social strengths with emotional difficulties: social adaptability and cross-cultural competence but also low self-esteem and shame regarding diff

Ethnocentrism and Perceptual Ambiguity

Description: Social scientists have been concerned for quite some time with the relationship between tolerance of perceptual ambiguity and ethnocentrism. Some investigations have approached the problem by utilizing ambiguous visual designs. It is the purpose of this research to add a new dimension to these studies by employing different types of visual figures and investigating relationships between perception and ethnocentrism.

Ethnogenesis and Captivity: Structuring Transatlantic Difference in the Early Republic, 1776-1823

Description: This study seeks to understand the development of early American ideas of race, religion, and gender as reflected in Indian and Barbary captivity narratives (tales of individuals taken captive by privateers in North Africa) and in plays that take American captives as their subject. Writers of both Indian and Barbary captivity narratives used racial and religious language – references to Indians and North Africans as demonic, physically monstrous, and animal – simultaneously to delineate Native American and North African otherness. The narrative writers reserved particular scorn for the figure of the Renegade – the willful cultural convert who chose to live among the Native Americans or adopt Islam and live among his North African captors. The narratives, too, reflect Early American gendered norms by defining the role of men as heads of household and women’s protectors, and by defining women by their status as dutiful wives and mothers. Furthermore, the narratives carefully treat the figure of the female captive with particular care – resisting implications of captive rape, even while describing graphic scenes of physical torture, and denying the possibility of willful transcultural sexual relationships.
