Images of a Gendered Kingship: Visual Representations of Hatshepsut and Her Influence on Images of Nefertiti (open access)

Images of a Gendered Kingship: Visual Representations of Hatshepsut and Her Influence on Images of Nefertiti

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.

Style and the Art of Chaim Soutine: Ethnicity, Nationalism and Geography in the Critical Reception and Historiography

Access: Use of this item is restricted to the UNT Community
This thesis argues that art criticism published during Soutine's lifetime emphasizes ethnicity, nationalism and geography in discussions of the artist's style. These critical discussions have influenced the historiography of Soutine published after his death, resulting in a continued emphasis on style that includes references to ethnicity. Ethnicity, nationalism and geography are identified in the critical reception and historiography by noting references, both specific and implied, to Jewishness, French art, and foreign status (among others). These references are analyzed in terms of existing scholarship that addresses concepts of ethnicity and nationalism, and with consideration to how the critical reception has impacted the historiography.

N-Acylethanolamine (NAE) Profiles Change During Arabidopsis Thaliana Seed Germination and Seedling Growth (open access)

N-Acylethanolamine (NAE) Profiles Change During Arabidopsis Thaliana Seed Germination and Seedling Growth

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.

Well-Being of Gifted Students Following Participation in an Early-College-Entrance Program (open access)

Well-Being of Gifted Students Following Participation in an Early-College-Entrance Program

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.

Longitudinal Study of the Impact of Performance Appraisals in Organizations

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to determine the effectiveness of and the subjects' overall satisfaction with the implementation of an internally created performance appraisal system. The system was implemented at a major technology consulting firm in the US. The subjects of this study were manager level employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of managers' responses to six key questions in the Career Development category were analyzed. Managers' perceptions of their contribution to the firm, their understanding of what career paths are available to them, their understanding of the requirements for promotion, as well as their overall satisfaction with the implementation of the performance appraisal system were captured by this survey. Trend analysis indicates that managers at the firm perceived their career path knowledge improved and their understanding of promotion criteria improved as a result of the implementation. Overall satisfaction with the implementation did not improve enough to site confidence in managers' perceptions for the period immediately after the implementation; managers' responses to the actual implementation were disagreeable to neutral. Managers did not feel their impact on the organization improved as …

Acceptance and use of corporal punishment among parents of biologic and non-biologic children. (open access)

Acceptance and use of corporal punishment among parents of biologic and non-biologic children.

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.

The Flora and Fauna in Eighteenth-Century Colonial Mexican Casta Paintings

Access: Use of this item is restricted to the UNT Community
The primary objective of this thesis is to identify patterns of appearance among the flora and fauna of selected eighteenth-century New Spanish casta paintings. The objectives of the thesis are to determine what types of flora and fauna are present within selected casta paintings, whether the flora and fauna's provenance is Spanish or Mexican and whether there are any potential associations of particular flora and fauna with the races being depicted in the same composition. I focus my flora and fauna research on three sets of casta paintings produced between 1750 and 1800: Miguel Cabrera's 1763 series, José Joaquín Magón's 1770 casta paintings, and Andrés de Islas' 1774 sequence. Although the paintings fall into the same genre and within a period of a little over a decade, they nevertheless offer different visions of New Spain's natural bounty and include objects designed to satisfy Europe's interest in the exotic.

Depression, Activities of Daily Living, and Retirement

Access: Use of this item is restricted to the UNT Community
Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better …

Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification

Access: Use of this item is restricted to the UNT Community
The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate while SR weight was, on average, underreported by 4.77 lbs. Because of these errors in SR height and weight, accuracy of classification into the FITNESSGRAM® HFZ was compromised. Consequently, it is important that researchers ascertain actual values of height and weight when measuring adolescents rather than use those from self-reports.

Supercritical Silylation and Stability of Silyl Groups

Access: Use of this item is restricted to the UNT Community
Methylsilsesquioxane (MSQ) and organosilicate glass (OSG) are the materials under this study because they exhibit the dielectric constant values necessary for future IC technology requirements. Obtaining a low-k dielectric value is critical for the IC industry in order to cope time delay and cross talking issues. These materials exhibit attractive dielectric value, but there are problems replacing conventional SiO2, because of their chemical, mechanical and electrical instability after plasma processing. Several techniques have been suggested to mitigate process damage but supercritical silylation offers a rapid single repair step solution to this problem. Different ash and etch damaged samples were employed in this study to optimize an effective method to repair the low-k dielectric material and seal the surface pores via supercritical fluid processing with various trialkylchlorosilanes. Fourier transform infrared spectroscopy (FTIR), contact angle, capacitance- voltage measurements, and x-ray photoemission spectroscopy, dynamic secondary ion mass spectroscopy (DSIMS), characterized the films. The hydrophobicity and dielectric constant after exposure to elevated temperatures and ambient conditions were monitored and shown to be stable. The samples were treated with a series of silylating agents of the form R3-Si-Cl where R is an alkyl groups (e.g. ethyl, propyl, isopropyl). Reactivity with the surface hydroxyls was inversely …

A morphological study of the avian (Gallus domesticus) ductus arteriosi during hatching.

Access: Use of this item is restricted to the UNT Community
The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences between the proximal and distal portions of the DA with regard to lumen occlusion, endothelial cells, smooth muscle and elastin. Endothelial cell proliferation begins to occur as early as external pipping, with the lumen almost completely occluded by the 3rd day of post-hatching life. Expression of vascular endothelial growth factor (VEGF) increases in avian endothelial cells during hatching. I provide a morphological timeline of changes in the DA as the chicken develops from embryo to hatchling.

Towards Communicating Simple Sentence using Pictorial Representations (open access)

Towards Communicating Simple Sentence using Pictorial Representations

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.

Increasing contact with, proximity to, and acceptance of new foods in a young child with autism. (open access)

Increasing contact with, proximity to, and acceptance of new foods in a young child with autism.

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.

A Longitudinal Study of Rape Attitude Correlates among College Men (open access)

A Longitudinal Study of Rape Attitude Correlates among College Men

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.

Using Reinforcement Learning in Partial Order Plan Space

Access: Use of this item is restricted to the UNT Community
Partial order planning is an important approach that solves planning problems without completely specifying the orderings between the actions in the plan. This property provides greater flexibility in executing plans; hence making the partial order planners a preferred choice over other planning methodologies. However, in order to find partially ordered plans, partial order planners perform a search in plan space rather than in space of world states and an uninformed search in plan space leads to poor efficiency. In this thesis, I discuss applying a reinforcement learning method, called First-visit Monte Carlo method, to partial order planning in order to design agents which do not need any training data or heuristics but are still able to make informed decisions in plan space based on experience. Communicating effectively with the agent is crucial in reinforcement learning. I address how this task was accomplished in plan space and the results from an evaluation of a blocks world test bed.

Language and the Art of Writing

Access: Use of this item is restricted to the UNT Community
I start writing by conjuring up an image in my mind. Sometimes it will be something that I have thought about for a while, sometimes it will be something that I sit around attempting to create. Either way, it is simply the idea that I need in order to get started. People will say, "Just sit down and write" which I can do, but it does not mean I will end up anywhere worthwhile. In my writing I need a focus. I need an idea or just one image to get me writing and I can base an entire story off of that one image. I think the reason this works for me is because in my mind it is an illustration and always something that is vibrant and unique. I want the image to stand out and to mean something because I feel that it comes to me for a specific reason, I just have to piece it all together and let the characters and plot unfold for themselves. People often say this, that the characters end up running the story. I think this is true, but in my case my stories are not so driven by character or …

Differential Scoring Patterns on the Clock Drawing Test: a Comparison of Vascular Dementia and Alzheimer's Dementia. (open access)

Differential Scoring Patterns on the Clock Drawing Test: a Comparison of Vascular Dementia and Alzheimer's Dementia.

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.

FACET Simulation in the Imataca Forest Reserve, Venezuela: Permanent Plot Data and Spatial Analysis (open access)

FACET Simulation in the Imataca Forest Reserve, Venezuela: Permanent Plot Data and Spatial Analysis

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.

An unjust legacy: A critical study of the political campaigns of William Andrews Clark, 1888-1901. (open access)

An unjust legacy: A critical study of the political campaigns of William Andrews Clark, 1888-1901.

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.

Individual Perceptions of a Proposed Pressure to be Positive in America (open access)

Individual Perceptions of a Proposed Pressure to be Positive in America

Positive psychology has become influential in research and practice. However, some have criticized positive psychologists who focus solely on the virtues of being positive. A tyrannical pressure to be positive may potentially exist in positive psychology, as well as mainstream United States culture. The following study explored perceptions of this theory using focus groups of individuals who differed in coping style, social desirability, and depression. Results suggest that individuals are affected by social pressures to be positive, and the expression of both positive and negative emotions is determined by social pressures, rules, context, and consequences. Although emotional expression, especially negativity, is contraindicated in several social contexts, there are also social, psychological, and physical benefits to all types of emotional expression.

Sounding sacred: Interpreting musical and poetic trances. (open access)

Sounding sacred: Interpreting musical and poetic trances.

This essay investigates the relationship between trance and various musical and poetic expressions that accompany trance when it is interpreted as sacred. In other words, the aim of this investigation is to interpret how experiences of the entrancing power of the sacred come to expression with the sounds of music and poetry. I articulate such an interpretation through the following four sections: I) a discussion of the basic phenomenological and hermeneutic problems of interpreting what other people experience as sacred phenomena, II) an account of the hermeneutic context within which modern Western discourse interprets trance as madness that perverts the rational limits of the self, III) an interpretation of the expressions of trance that appear in the poetry of William Blake, and IV) an interpretation of expressions of trance that appear in the music of Afro-Atlantic religions (including Vodu in West Africa, Santería in Cuba, and Candomblé in Brazil).

Family dynamics and students' characteristics as predictors of undergraduate college student adjustment. (open access)

Family dynamics and students' characteristics as predictors of undergraduate college student adjustment.

The problem addressed is to ascertain how selected factors impacted the adjustment of undergraduate university students. Undergraduate university students (n=382) from the University of North Texas completed measures of basic student information, perceived level of family support and level of parental attachment, and perceived level of college student adjustment. Parental Attachment and Family Support were found to positively correlate to the level of adjustment to college. Analyses of these data reveal a statistically significant difference in student adjustment to college when comparing the participants by age, university classification, and living arrangement. Further analysis reveals that there is a statistically significant difference between gender, race, students' marital status, and parents' marital status when measuring the outcome of perceived family support. Perceived level of parental attachment differs significantly when comparing students by their race, marital status, and their parents' marital status.
