I investigate why gendered images of Hatshepsut influenced androgynous images of Nefertiti in New Kingdom Egypt and how Nefertiti and Akhenaten used their images in the promotion of their monotheistic religion; through a contextual, stylistic and feminist examination of the images. Hatshepsut cultivated images of herself to legitimize her rule in relation to canonical kings before her. Similarly, Nefertiti represented herself as a figure indiscernible from Akhenaten, creating an image of female co-rulership. Although the visual representations of both Hatshepsut and Nefertiti differ, the concepts behind each are analogous. They both manipulated androgyny to create images displaying powerful women equal in status to male Egyptian kings.

An understanding of the potential roles as lipid mediators of a family of bioactive metabolites called N-acylethanolamines (NAEs) depends on their accurate identification and quantification. The levels of 18C unsaturated NAEs (e.g. NAE18:2, NAE 18:3, etc.) in wild-type seeds (about 2000 ng/g fw) generally decreased by about 80% during germination and post-germinative growth. In addition, results suggest NAE-degradative fatty acid amide hydrolase (FAAH) expression does not play a major role in normal NAE metabolism as previously thought. Seedlings germinated and grown in the presence of abscisic acid (ABA), an endogenous plant hormone, exhibited growth arrest and secondary dormancy, similar to the treatment of seedlings with exogenous N­lauroylethanolamine (NAE12:0). ABA-mediated growth arrest was associated with higher levels of unsaturated NAEs. Overall, these results are consistent with the concept that NAE metabolism is activated during seed germination and suggest that the reduction in unsaturated NAE levels is under strict temporal control and may be a requirement for normal seed germination and post-germinative growth.

The concepts of well-being and life satisfaction are explored in this study of the experiences and psychological traits of highly-gifted students who have been radically accelerated into an early-college-entrance program. The study was conducted after participation in the early-college-entrance program. The primary focus of the study is on personal well-being and life satisfaction including the variables of subjective well-being, efficacy, and the dispositional traits of cheerfulness, seriousness, and bad mood. These variables are gathered as the initial phase of a longitudinal study of the early-college entrants' personal and professional experiences, their life satisfaction, and dispositions. The subjects for this study were participants in the Texas Academy of Math and Science (TAMS). TAMS is a state run early-college-entrance program at the University of North Texas in Denton.

This study examines occupational aspiration and choice of traditional first-time college students utilizing longitudinal data from the Cooperative Institutional Research Program (CIRP). Focus is given to beliefs about the importance of family and money in relation to selection of an occupation that is classified as sex-typed. Change from one occupational category to another is also considered. The dissonance between students' beliefs about the importance of family and money as associated with their sex-typed occupational choice is explored. Understanding students' occupational plans that subsequently determine future prestige, wealth, and status is vital to higher educational professionals who facilitate students in their career selection and major. Therefore, environmental factors of satisfaction with career counseling and academic advising are examined. The U.S. Census Equal Employment Opportunity (EEO) data is applied in the classification of sex-typed occupations. Race and ethnicity is investigated to determine if the same gender patterns exist among cultural groups with regards to their occupational selection. The results indicate that students' occupational aspirations were influenced by their belief regarding the importance of family or money. In addition, their beliefs regarding family and money changed after four years of college with family increasing in importance. Strong beliefs that were, either concordant or …

Objective: Differences between biologic and non-biologic parents' acceptance and use of ordinary corporal punishment and use of explaining/reasoning as a disciplinary tool are examined from a sociobiological theoretical perspective. Method: Cross tabulations are used on data from a national survey conducted by the Gallup Organization in 1995. Results: Contrary to predictions, differences between biologic and non-biologic parents' acceptance of ordinary corporal punishment and the use of explaining/reasoning are not statistically significant. In addition, biologic parents are found to use ordinary corporal punishment significantly more often than non-biologic parents. Conclusions: The sociobiological theoretical perspective likely underestimates the influence of culture and social structure on parent-child interactions.

For rare book collections, a considerable challenge is involved in evaluating collection materials in terms of their inherent value, which includes the textual and intangible information the materials provide for the collection's users. Preservation management in rare book collections is a complex and costly process. As digitization and other technological advances in surrogate technology have provided new forms representation, new dilemmas in weighing the rare book's inherently valuable characteristics against the possibly lesser financial costs of surrogates have arisen. No model has been in wide use to guide preservation management decisions. An initial iteration of such a model is developed, based on a Delphi-like iterative questioning of a group of experts in the field of rare books. The results are used to synthesize a preservation management framework for rare book collections, and a small-scale test of the framework has been completed through two independent analyses of five rare books in a functioning collection. Utilizing a standardized template for making preservation decisions offers a variety of benefits. Preservation decisions may include prioritizing action upon the authentic objects, or developing and maintaining surrogates in lieu of retaining costly original collection materials. The framework constructed in this study provides a method for reducing …

The primary purpose of this study was to test the theory of experiential learning by measuring to what extent work experience predicts the work ethic characteristics of students in baccalaureate nursing programs at three regional universities in Texas, including Midwestern State University in Wichita Falls, Tarleton State University in Stephenville, and West Texas A&M University in Canyon. Work experience is the amount full-time or part-time on-the-job experience. Work ethic attributes are referred to as considerate, ambitious, dependable, and cooperative. Results generated in this study failed to reject the null hypotheses, which means that work experience, does not provide evidence of the ability to predict the development of work ethic characteristics in baccalaureate nursing students who participated in this research study. Knowledge generated in this study provided alternative directions for future research with respect to the relationship between work experiences and work ethic characteristics in nursing students. Such research may be useful to nursing educators and trainers in the design and delivery phases of the educational process for nurses.

This mixed design study surveyed members of the National Association of Student Personnel Administrators (NASPA) to determine the baseline for wellness among student affairs administrators and within the profession. In addition to describing the wellness levels of the administrators and comparing them to the wellness of the general population, the study explored how wellness is represented within the student affairs profession, as reflected in the literature and practice. Student affairs administrators' wellness was assessed utilizing the Five Factor Wel Wellness Inventory (Myers & Sweeney, 2004). Collectively, the administrators posted "well" scores on the six factors utilized in the study and scored higher than the norms reported for the 5F-Wel general population. However, there was a broad range of actual scores across individuals indicating that not everyone can be considered to be maintaining a well-balanced lifestyle. The administrators' wellness was not affected by their length of time in the student affairs profession but was negatively associated with the number of hours they worked per week. The administrators possessed a holistic view of wellness and could articulate the behaviors and conditions associated with achieving, and failing to achieve, balance. However, reported engagement in certain wellness behaviors (e.g., physical activity and healthy eating) …

Language can sometimes be an impediment in communication. Whether we are talking about people who speak different languages, students who are learning a new language, or people with language disorders, the understanding of linguistic representations in a given language requires a certain amount of knowledge that not everybody has. In this thesis, we propose "translation through pictures" as a means for conveying simple pieces of information across language barriers, and describe a system that can automatically generate pictorial representations for simple sentences. Comparative experiments conducted on visual and linguistic representations of information show that a considerable amount of understanding can be achieved through pictorial descriptions, with results within a comparable range of those obtained with current machine translation techniques. Moreover, a user study conducted around the pictorial translation system reveals that users found the system to generally produce correct word/image associations, and rate the system as interactive and intelligent.

The effects of two positive reinforcement procedures were evaluated to increase contact with, proximity to, and acceptance of new foods in a young child with autism. During baseline, two groups of six food items were presented. One group was intervened on. The first condition involved a changing criterion contingency and social attention as a consequence. The second involved a shaping contingency and access to videos as a consequence. The types of contact emitted, the amount of time spent contacting the food, and two affect topographies were measured. The second procedure resulted in increased duration and variety of contact, and increases of both affect topographies. Results are discussed in the context of food selectivity in autism, programming goals, and balancing intervention efficacy and restrictiveness.

In recent years, the accounting profession has faced increased scrutiny because of scandals involving management fraud (e.g., Enron, WorldCom). In response, Statement on Auditing Standards (SAS) #99 has expanded auditors' responsibility for detecting fraud, requiring auditors to gather significantly more information in their assessment of fraud. In addition, the Public Company Accounting Oversight Board (PCAOB) will focus on fraud detection through their inspections of registered accounting firms. In light of the increased emphasis on auditors' responsibility for detecting fraud, public accounting firms face the challenge of improving their fraud detection process, including their assessment of management fraud risk. Decision aids are one way for auditors to improve their assessment of management fraud risk. In fact, several studies from the decision aid literature suggest that aids are useful tools for a variety of tasks, including fraud risk assessment. At the same time, another stream of the decision aid reliance literature, which looks at people's willingness to rely on decision aids, suggests that individuals tend to be reluctant to accept the output given by an aid. Thus, the primary focus of this paper is on uncovering factors that would encourage one to voluntarily use and rely upon a decision aid. Toward that …

This study describes the experiences of doctoral students in education at Historically Black Colleges and Universities (HBCUs). The study focused only on the 14 HBCUs that offer doctoral degrees in education. Twelve of the 14 eligible institutions agreed to participate in the study. A total of 47 doctoral students who were in their third year of study or close to completion participated in the study. These doctoral students completed a survey that was utilized in a national study of doctoral students at predominately white institutions and Ivy League institutions conducted by Golde and Dore in 2001. The purpose of this study was to determine if doctoral students in education at HBCUs are receiving a quality education and if they are being adequately prepared for their careers. This study offers 368 findings from which the doctoral experience in education at HBCUs can be comprehensively evaluated. It was determined that doctoral students in education at HBCUs do receive a quality education and are being effectively prepared for their careers.

Abstract This dissertation investigates authentication techniques in some emerging areas. Specifically, authentication schemes have been proposed that are well-suited for embedded systems, and privacy-respecting pay Web sites. With embedded systems, a person could own several devices which are capable of communication and interaction, but these devices use embedded processors whose computational capabilities are limited as compared to desktop computers. Examples of this scenario include entertainment devices or appliances owned by a consumer, multiple control and sensor systems in an automobile or airplane, and environmental controls in a building. An efficient public key cryptosystem has been devised, which provides a complete solution to an embedded system, including protocols for authentication, authenticated key exchange, encryption, and revocation. The new construction is especially suitable for the devices with constrained computing capabilities and resources. Compared with other available authentication schemes, such as X.509, identity-based encryption, etc, the new construction provides unique features such as simplicity, efficiency, forward secrecy, and an efficient re-keying mechanism. In the application scenario for a pay Web site, users may be sensitive about their privacy, and do not wish their behaviors to be tracked by Web sites. Thus, an anonymous authentication scheme is desirable in this case. That is, a …

In response to a growing teacher shortage, increasing numbers of secondary teachers are prepared through streamlined certification programs. For this reason, assessing candidates' content area knowledge gained from institutions of higher education across the United States is an important program admission factor as candidates must demonstrate content area knowledge by passing a Texas content area certification test (TExES). This study examines content knowledge for candidates enrolled in an online post­-baccalaureate program from September 1, 2002 through April 30, 2005. Academic transcript analysis and grades 8-­12 subject tests of the TExES were used as a proxy for subject matter knowledge for a sample of individuals seeking initial teacher certification in a post­-baccalaureate teacher certification at the University of North Texas. Descriptive data,linear regression, and logistic regression analyses were used to draw conclusions about the content area knowledge of the individuals in the sample. Scores on the TExES were used to determine the relationships between the content area knowledge of initial certification students and the number of content area courses completed, the grade point averages, and time elapsed between the completion of the last content area course and the student's initial attempt on the TExES. Results differed by the content area of …

The purpose of this research was to manipulate the component of confidence found in Keller's ARCS model to enhance the confidence and performance of undergraduate students enrolled in an online course at a Texas university using SAM 2003 software delivery. This study also tested whether the aforementioned confidence tactics had any unintentional effect on the remaining attention, relevance, and satisfaction subscales of the ARCS model as well as on learners' overall motivation for the class and the instructional materials. This study was conducted over a 5.5-week period with an initial sample of 81 total students. Two quantitative surveys were used to measure confidence and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). The results indicated that the treatment group showed statistically greater gains than the control group in terms of learner confidence on the CIS but not the IMMS. In terms of performance, the treatment group outperformed the control group on all of the individual posttest measures and on the overall aggregate mean performance score. The results showed no statistically significant difference on the attention subsection of the ARCS model. However, statistically significant differences were noted for the relevance and satisfaction subscales of …

This study compared strategy use and beliefs about language learning, and the relationship between beliefs and use reported by 428 monolingual Korean and 420 bilingual Korean-Chinese university students. This study also examined the influence of background variables (e.g., gender, self-rated English proficiency, and academic major) on learners' beliefs and strategy use. Data was collected using three questionnaires, the Strategy Inventory for Language Learning (SILL), the Beliefs about Language Learning Inventory (BALLI), and the Individual Background Questionnaire (IBQ). Data were analyzed using descriptive analyses, principal-component analyses, factor analyses, Pearson r correlation analyses, multivariate analysis of variance (MANOVA), and the Scheffé post-hoc test. Monolinguals reported using compensation strategies most, followed by cognitive, metacognitive, memory, social/practical practice, and affective strategies. Bilinguals preferred to use cognitive strategies most, followed by metacognitive and affective, compensation, memory, social, and independent practice strategies. Students from both groups reported low use of social and memory strategies. Despite a less favorable formal English education environment in the Korean-Chinese community and fewer English learning experiences, bilingual Korean-Chinese reported higher use of learning strategies, which indicates bilinguals' superior language learning abilities. Students from both groups had strong instrumental motivation for learning English. Bilinguals held stronger beliefs about the importance of formal …

Research has linked rape victim-blaming attitudes (VBAs) with gender role stereotyping, negative peer attitudes towards women, and acceptance of interpersonal violence. The current study analyzed longitudinal questionnaire data of college men (n=166) from White and Smith's (2001) study of college student victimization. Results indicate that VBAs can be conceptualized as either overt or covert, and that the covert VBA was more strongly correlated with alcohol use, sexualized peer attitudes, traditional gender stereotypes, need for sexual dominance, and perpetration of dating aggression. The covert VBA was also correlated with rape proclivity one year later, and partially mediated relationships between earlier variables and later rape proclivity. Additionally, endorsement of chivalry moderated the relationship between traditional gender stereotypes and the covert VBA, casting new perspective on the role of chivalry. Overall, results demonstrate the importance of targeting subtle expressions of VBAs in educational programs, and the need for longitudinal studies on rape attitude development.

This study examined differences in scoring patterns among those diagnosed with Alzheimer's dementia and vascular dementia on the clock-drawing test. Archival clock drawing data was retrieved on 279 patients presenting at a county hospital-based memory clinic. Analysis of drawings was based on frequency of qualitative errors, as well as an overall quantitative score. Mean comparisons found those patients with Alzheimer's dementia to perform worse on both quantitative and qualitative scoring measures. However, Pearson's chi-squared test revealed a significantly higher rate of spacing errors among subjects with vascular dementia. Such lends support to my hypothesis that impaired executive functioning in vascular dementia patients would lead to poor qualitative performance. Logistic regression found significant predictive ability for the qualitative criteria in diagnosis (χ2 = 25.49, p < .001), particularly the rate of omission (z = 8.96, p = .003) and addition errors (z = 7.58, p = .006). Such findings hold important implications for the use of qualitative criteria in cognitive screening assessments.

Tree diameter data from 29 years of observations in six permanent plots was used to calculate the growth rate parameter of the FACET gap model for 39 species in the Imataca forests in Venezuela. The compound topographic index was used as a measure of differential soil water conditions and was calculated using geographic information systems. Growth rate values and topographic conditions typical of hill and valley were input to FACET to simulate dynamics at the species level and by ecological and functional groups. Species shade-tolerance led to expected successional patterns. Drought-tolerant/saturation-intolerant species grew in the hills whereas drought-intolerant/saturation-tolerant species occurred in the valleys. The results help to understand forest composition in the future and provide guidance to forest management practices.

The Texas high school class of 2005 faced a defining test that had no precedent in Texas and little nationally. Social studies testing is a relatively new addition to the world of high stakes testing currently impacting United States high schools. Although other diploma dependent areas of mandated testing have some testing history and, therefore, related paradigms for curriculum and instructional assistance, the area of social studies largely lacks that perspective. Texas Education agency provided specific school grant monies and training for the purpose of preparation for the social studies exams. This quasi-experimental study examines the scores to learn whether or not any statistically significant differences in social studies scores would exist between the schools that participated in the TEKS/Tools Training Program and the schools that did not participate in the TEKS/Tools Training Program. The two primary at-risk groups in Texas, Hispanic and low SES, were analyzed for statistically significant differences in scores. Independent t tests and ANCOVA were used to analyze the score differences between program schools and non-program schools. Results relate to individual school staffing and implementation. The at-risk groups remained flat in score gains whether they were part of the program schools or not. Results relate to …

Opto-electronic semiconductor technology continues to grow at an accelerated pace, as the industry seeks to perfect devices such as light emitting diodes for purposes of optical processing and communication. A strive for greater efficiency with shrinking device dimensions, continually pushes the technology from both a design and materials aspect. Nanosystems such a quantum dots, also face new material engineering challenges as they enter the realm of quantum mechanics, with each system and material having markedly different electronic properties. Traditionally, the semiconductor industry has focused on materials such Group II-VI and III-V compounds as the basis material for future opto-electronic needs. Unfortunately, these material systems can be expensive and have difficulties integrating into current Si-based technology. The industry is reluctant to leave silicon due in part to silicon's high quality oxide, and the enormous amount of research invested into silicon based circuit fabrication. Although recently materials such as GaN are starting to dominate the electro-optical industry since a Si-based substitute has not been found. The purpose of the dissertation was to examine several promising systems that could be easily integrated into current Si-based technology and also be produced using simple inexpensive fabrication techniques such ion implantation. The development of optically active …

This study provides a detailed description of revenue and expenditure patterns of the United States community college by state and by institutional type (rural-, suburban-serving, and urban-serving) for each five-year period from 1980-81 to 2000-01. The Katsinas, Lacey, and Hardy classification schema for community colleges is used to analyze data from the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS) and Higher Education General Information Surveys (HEGIS). Further analysis clusters states into the following groupings: states with/without substantial local funding, large "mega-states" versus all other states (employing the methodology developed by Grapevine at Illinois State University), and the structure of state coordination (as developed by Tollefson and others in their studies of state community college systems). The analysis showed wide differences in the various funding patterns for community colleges as related to revenue streams. As late as 1980-91, 16 states contributed 60% or more of the total budgets for their community colleges; by 2000-01, no state did so. By college type, rural-serving community colleges saw the greatest net negative change in their operating budget margins, from 3.2% to 0.4%, although it should be noted that every one of the community college types also experienced a significant decline …

The purpose of this study was to determine if any statistically significant difference exists between the self-efficacy scores of student teachers who began their college experience at the community college level and student teachers who began their education at the university level. The study was used to determine whether or not the type of initial college experience impacted the first two years of college study, in relation to the development of a sense of self-efficacy at the end of the program of study. Self-efficacy data were gathered from beginning student teachers at two comparative institutions. The participants were enrolled in the colleges of education at two large metropolitan universities. One university was located in southern Texas and the other was located in north central Texas. The Teachers' Sense of Efficacy Scale was the instrument used, as well as a researcher-made questionnaire that collected demographic data. In addition to pattern of education, other independent variables included age, gender, ethnicity, certification level sought by the participant, and the number of contact hours spent by the participant in early field experiences in K-12 classrooms. A multiple regression analysis indicated no statistically significant difference in the composite score of the Teachers' Sense of Efficacy …

In a time of laissez-faire government, monopolistic businesses and political debauchery, William Andrews Clark played a significant role in the developing West, achieving financial success rivaling Jay Gould, George Hearst, Andrew Carnegie, and J. P. Morgan. Clark built railroads, ranches, factories, utilities, and developed timber and water resources, and was internationally known as a capitalist, philanthropist and art collector. Nonetheless, Clark is unjustly remembered for his bitter twelve-year political battle with copper baron Marcus Daly that culminated in a scandalous senatorial election in January 1899. The subsequent investigation was a judicial travesty based on personal hatred and illicit tactics. Clark's political career had national implications and lasting consequences. His enemies shaped his legacy, and for one hundred years historians have unquestioningly accepted it.
