Protecting Patriarchy: an Historical/Critical Analysis of Promise Keepers, an All-Male Social Movement

Description: The historical survey of social movements in the United States reveals that the movement is a rhetorical ground occupied by groups who have been marginalized by society. Today, however, the distinctions between those who are marginalized and those who are part of the establishment have become difficult to distinguish. This study considers the emergence of Promise Keepers, an all-male social movement, and the rhetorical themes that emerge from the group. This study identifies five rhetorical themes in Promise Keepers. These themes include asserting authority of men in the home and church, the creation of a new male identity, sports and war rhetoric, political rhetoric, and racial reconciliation. The implications of these themes are considered from a critical perspective and areas for future research are provided.

Transcendentalism and Intertextuality in Charles Ives's War Songs of 1917

Description: This thesis examines a collection of three songs, "In Flanders Fields," "He Is There!," and "Tom Sails Away," written by Charles Ives in 1917, from primarily a literary perspective involving Transcendentalism and intertextuality. Ives's aesthetic builds upon the principles of Transcendentalism. I examine these songs using the principles outlined by the nineteenth-century Transcendentalists, and Ives's interpretations of these beliefs. Another characteristic of Ives's music is quotation. "Intertextuality" describes an interdependence of literary texts through quotation. I also examine these songs using the principles of intertextuality and Ives's uses of intertextual elements. Familiarity with the primary sources Ives quotes and the texts they suggest adds new meaning to his works. Transcendentalism and intertextuality create a greater understanding of Ives's conflicting views of the morality of war.

A Comparison of Teachers' Sense of Efficacy of Traditionally and Alternatively Certified First Year Teachers

Description: The purpose of this study was to compare the self-efficacy of two groups of first year teachers working in a large urban school district in North Texas. Twenty-eight of the participants were certified teachers. Ten participants held college degrees unrelated to teaching and were undergoing an alternative certification process. The Teacher Efficacy Scale was administered at the beginning and the end of the school year. Data from this scale was analyzed to determine if there were differences between the regular certification teachers and the alternative certification teachers at the beginning and the end of the school year, and to determine if their sense of efficacy changed over the course of the school year.

Language Contact in the Inner City: the Acquisition of AAVE Features by Bilingual Hispanic Adolescents

Description: Sociolinguists working in Northern urban areas have shown that Hispanics who come in contact with African Americans sometimes acquire features of African American vernacular English (AAVE). However, the acquisition of AAVE features by Hispanics in the South has yet to be documented. Specifically, no one has studied the kind of English that Hispanics in Texas are acquiring. The present study investigates this issue through research in an inner-city area of Dallas: Oak Cliff. During the past twenty-five years, the population of Oak Cliff has changed from a largely African American community to include a substantial number of Hispanics. Though their neighborhoods remain fairly separate, sports and gangs provide an arena for extended contact. This study investigates the extent to which AAVE grammatical features are being acquired by bilingual Hispanic adolescents who hang out with African Americans. The analysis for this paper focuses on the relationship between contact and depth of acquisition of AAVE syntactic constraints on the use the copula (is/are, be). Preliminary results show that be+V+ing as an habitual form has been incorporated into the grammar of these subjects, suggesting fundamental changes towards an AAVE grammatical system.

Investigating the Delivery of Therapeutic Recreation Services on the Internet: a Pilot Study Using Leisure Education for the Prevention of Alcohol Abuse

Description: This pilot study, grounded in social learning theory, demonstrated that leisure education services can be delivered on the Internet. Participants (n=40) successfully accessed the Web page program and responded to instruments and surveys. The treatment group (n=16) effectively completed four leisure education sessions on-line. Confidentiality, privacy, and anonymity issues were controlled. Responses were monitored and feedback provided as to the complexity of the program and comprehension of the participants. The leisure education program had no significant effect on posttest measures of alcohol expectancies and leisure motivations. Mean changes frompretest to posttest may indicate trends. The small n and convenience sample may have introduced many extraneous variables. Professional implications include compliance issues (57% experimental mortality rate), technology-related anxiety, and limited professional competency to work in this environment. Future research which examines the provision of leisure education and other components of therapeutic recreation service on-line is warranted.

Protection or Equality? : A Feminist Analysis of Protective Labor Legislation in UAW v. Johnson Controls, Inc.

Description: This study provides a feminist analysis of protective labor legislation in the Supreme Court case of UAW v. Johnson Controls, Inc. History of protection rhetoric and precedented cases leading up to UAW are provided. Using a feminist analysis, this study argues that the victory for women's labor rights in UAW is short lived, and the cycle of protection rhetoric continues with new pro-business agendas replacing traditional justifications for "protecting" women in the work place. The implications of this and other findings are discussed.

An Assessment of College Students' Attitudes and Empathy toward Rape

Description: The purpose of this study was to assess rape attitudes and empathy levels of students at a university in North Texas. The Attitudes Toward Rape questionnaire and the Rape Empathy Scale were administered to 387 undergraduate students. Dependent variables were attitudes and empathy and independent variables were prior knowledge or experience as a rape victim, having female siblings, gender, marital status, and age. Significance was found between rape-intolerant attitudes and both prior experience as a victim (p < .001), and gender (p < .001). Significance was also found between empathy and experience as a rape victim (p < .035) and gender (p < .032).

Stoichiometry and Deposition Temperature Dependence of the Microstructural and Electrical Properties of Barium Strontium Titanate Thin Films

Description: Barium Strontium Titanate (BST) was deposited on Pt/ZrO2 / SiO2/Si substrates using liquid source metal organic chemical vapor deposition. A stoichiometry series was deposited with various GrII/Ti ratios (0.658 to 1.022) and a temperature series was deposited at 550 to 700°C. The thin films were characterized using transmission electron microscopy. Both series of samples contained cubic perovskite BST and an amorphous phase. The grain size increased and the volume fraction of amorphous phase decreased with increasing deposition temperature. The electrical and microstructural properties improved as the GrII/Ti ratio approached 1 and deteriorated beyond 1. This research demonstrates that BST thin films are a strong candidate for future MOS transistor gate insulator applications.

Development and Validation of a Two Factor Model of Adult Career Orientation

Description: Subjects in this study were 5,523 respondents from a survey which was sent to households throughout the United States. The purpose of this study was to examine two basic components of career orientation: career indecision and career insight. Correlational analyses found relationships between career indecision and average job tenure, industry leaving intentions, industry staying intentions, and job satisfaction. Correlational analyses found relationships between career insight, industry staying intentions and job satisfaction. Multiple regression analyses were run using both career indecision and career insight as independent variables found that they had useful levels of incremental validity in predicting industry leaving intentions and job satisfaction. Potential uses of the two-dimensional career indecision - career insight model are discussed.

Development and Application of an Assessment Protocol for Watershed Based Biomonitoring

Description: With numerous bioassessment methodologies available, a regional protocol needs to be developed to ensure that results are comparable. A regional assessment protocol was developed that includes collecting five benthic macroinvertebrate samples, identifying organisms to genus, and calculating the following metrics: Number of Taxa, Total Number of Individuals, Simpson's Diversity Index, Shannon's Diversity Index, Percent Contribution of Dominant Taxa, Hilsenhoffs Biotic Index, and Percent Contribution of Dipterans. Once the protocol was developed, it was used to assess the Bayou Chico tributaries and watershed. All three tributaries had been significantly impacted by human activity as had the watershed as a whole. This study indicates that a regional protocol could be developed and is appropriate for biomonitoring at the watershed scale.

An Examination of the Criterion-Related Validity of a Developmental Assessment Center

Description: The purpose of this study was to investigate the criterion-related validity of an assessment center's competency dimension ratings, exercise ratings, and standardized test scores. Numerous studies have clearly demonstrated assessment centers display substantial evidence of content and criterion-related validity. However, the inability of assessment centers to display construct-related validity has caused a great deal of concern among researchers. The suggestions of these researchers are addressed through a more detailed examination of the criterion-related validity of an assessment center. Despite a number of methodological issues, two competency dimensions and two components stand out as viable predictors of the criteria used in this study. Examination of individual and incremental validity coefficients reveals the Strategic Focus and Attracting and Developing Talent competency dimensions, the In-Basket exercise, and the Watson-Glaser scaled score consistently predict the criteria used in this study. The implications of these results for future research are discussed.

Non-Academic Institutional Variables Related to Degree Completion of Non-Traditional Age Undergraduate Students

Description: A study was conducted at The University of Texas at Arlington to obtain measurements of non-traditional age undergraduate students using the Mattering Scales for Adult Students in Higher Education (MHE). The MHE is designed to assess the perceptions of adult students on how much they matter to the institution they are attending. The study also sought to determine if "mattering" and other selected nonacademic variables associated with the university environment are perceived by nontraditional age students to effect their likelihood of completing their baccalaureate degree. Of the five subscales surveyed by the MHE, significant statistical differences were found to exist in the Administration, Interaction With Peers, Multiple Roles, and Faculty subscales denoting an interaction between gender and minority status. Significant statistical differences were also found by gender on the Advising subscale and by minority status on the Faculty subscale.

Technology Infusion in Career Services at U.S. Institutions of Higher Education in the Southwest

Description: The purpose of this study was to examine the use of computer and communications technologies at four-year public/private college and university career centers that are members of the Southwest Association of Colleges and Employers (SWACE). The findings of this study reveal that (a) all career centers are now using computer and telecommunications technologies for at least one office function; (b) small institutions do not use technologies as much as large institutions because they have fewer financial resources, less technical support from institutions, fewer personnel, and they also need time to learn to use technologies effectively; (c) public career centers are more willing to explore new technologies but private career centers mostly adopt and implement proven technologies; (d) career education does not utilize technologies as much as career counseling or job placement functions; (e) lack of financial resources and lack of technical support are major barriers to a technological infusion; and (f) technologies, including electronic student databases, computerized presentations with the network connection, and OCR scanners, will be needed in the near future.

Juan Bautista Maino's Adoration of the Shepherds: An Analysis of Iconography, Iconology, and Style

Description: This thesis investigates the iconography, iconology, and style of Juan Bautista Maino s Adoration of the Shepherds (1615-1620) located at the Meadows Museum, Dallas, Texas. The study begins with an overview of general information on Maino and his works. Chapter 2 explores the evolution of the Adoration of the Shepherds depiction in art, while examining social and political factors which may have influenced Maino's iconographical choices. Chapter 3 is a comparative analysis of the Meadows Adoration of the Shepherds to two other Adoration of the Shepherds by Maino, revealing a stylistic progression and presenting an argument for the dates the Meadows painting was rendered. Chapter 4 reviews the findings and suggests further study on this and other paintings by Maino.

Plane Curves, Convex Curves, and Their Deformation Via the Heat Equation

Description: We study the effects of a deformation via the heat equation on closed, plane curves. We begin with an overview of the theory of curves in R3. In particular, we develop the Frenet-Serret equations for any curve parametrized by arc length. This chapter is followed by an examination of curves in R2, and the resultant adjustment of the Frenet-Serret equations. We then prove the rotation index for closed, plane curves is an integer and for simple, closed, plane curves is ±1. We show that a curve is convex if and only if the curvature does not change sign, and we prove the Isoperimetric Inequality, which gives a bound on the area of a closed curve with fixed length. Finally, we study the deformation of plane curves developed by M. Gage and R. S. Hamilton. We observe that convex curves under deformation remain convex, and simple curves remain simple.

Characterization of Aspartate Transcarbamoylase and Dihydroorotase in Moraxella Catarrhalis

Description: Bacterial aspartate transcarbamoylases (ATCase's) are divided into three classes that correspond to taxonomic relationships within the bacteria. The opportunistic pathogen Moraxeila catarrhalis has undergone several reclassifications based on traditional microbiological criteria. The previously uncharacterized ATCase from M. catarrhalis was purified to homogeneity and its chemical properties characterized. The ATCase from M. catarrhalis is a class C ATCase with an apparent molecular mass of 480-520 kDa. The M. catarrhalis ATCase is a dodecomer composed of six 35 kDa polypeptides and six 45 kDa polypeptides. The enzyme has an unusually high pH optimum of greater than pH 10. The enzyme exhibited hyperbolic kinetic with a Km for aspartate of 2 mM. A single, separate 78 kDa dihydroorotase from M. catarrhalis was identified and it was not associated with ATCase. These data support the reclassification of M. catarrhalis out of the Neisseriaceae family.

Re-examining the Battle of the Bulge : Assessing the Role of Strategic Intelligence and Coalition Warfare Against the 1944 Wehrmacht

Description: The 1944 German Ardennes offensive failed. It was overly ambitious, built on erroneous assumptions, insufficiently supported by logistics, and depended on the weather for success. Yet, the offensive achieved more than it should have given the strength and combat experience of the Allied armies in Europe. Previous attempts to explain the limited success of the German offensive have emphasized the failure of Allied strategic intelligence - Ultra. Intelligence is an accurate, but incomplete explanation for initial German success in the Ardennes. Three conditions allowed the Wehrmacht, approaching its manpower and logistical end, to crush the US First Army. First, coalition warfare so weakened the First Army that it became vulnerable to attack. Second, the Allies failed to develop a unified intelligence network capable of assessing the information that indicated the timing and target of the German attack. Finally, a well-executed German security and deception plan surprised the Allies. The well-executed German offensive manipulated both Allied intelligence and the Anglo-American coalition.

Primitive Substitutive Numbers are Closed under Rational Multiplication

Description: Lehr (1991) proved that, if M(q, r) denotes the set of real numbers whose expansion in base-r is q-automatic i.e., is recognized by an automaton A = (Aq, Ar, ao, δ, φ) (or is the image under a letter to letter morphism of a fixed point of a substitution of constant length q) then M(q, r) is closed under addition and rational multiplication. Similarly if we let M(r) denote the set of real numbers α whose base-r digit expansion is ultimately primitive substitutive, i.e., contains a tail which is the image (under a letter to letter morphism) of a fixed point of a primitive substitution then in an attempt to generalize Lehr's result we show that the set M(r) is closed under multiplication by rational numbers. We also show that M(r) is not closed under addition.
