A study of on-line use and perceived effectiveness of compliance-gaining in health-related banner advertisements for senior citizens.
This research investigated banner ads on the World Wide Web, specifically the types of messages used in those ads and the effectiveness of the ads as seen by their intended audience. The focus was on health-related banner advertisements targeting senior citizens. The study first sought to determine the frequency of appearance of those ads when classified into categories of compliance-gaining tactics provided by research scholars. Second, the study explored the relative perceived effectiveness among those categories. Two graduate students from a Central Texas university sorted text messages into predetermined compliance-gaining categories. Chi square tests looked for significant differences in the frequencies of banner ads in each category. Forty-five senior citizens from the Central Texas area completed surveys regarding the perceived effectiveness of a randomly ordered, randomly selected set of categorized banner ads. A repeated measures test attempted to determine whether some compliance-gaining strategies used in health-related banner ads were perceived as more effective than others. The hypothesis stated that there would be differences in frequencies of compliance-gaining strategies used among the compliance-gaining categories in health-related banner ads for senior citizens. The hypothesis was supported. The research question asked if some categories of compliance-gaining strategies used in health-related banner ads were …

Radio frequency propagation differences through various transmissive materials.
The purpose of this research was to determine which of the commonly used wireless telecommunication site concealment materials has the least effect on signal potency. The tested materials were Tuff Span® fiberglass panels manufactured by Enduro Composite Systems, Lexan® XL-1 polycarbonate plastic manufactured by GE Corporation and Styrofoam polystyrene board manufactured by The Dow Chemical Company. Testing was conducted in a double electrically isolated copper mesh screen room at the University of North Texas Engineering Technology Building in Denton, Texas. Analysis of the data found no differences exist between the radio frequency transmissiveness of these products at broadband personal communication service frequencies. However, differences in the signal do exist with regards to the angle of incidence between the material and the transmitting antenna.

Ecology of Chironomids Associated with Myriophyllum Spicatum L. and Heteranthera Dubia Macm
Macroinvertebrate communities inhabiting an exotic, Myriophyllum spicatum, and a native, Heteranthera dubia macrophyte were studied from March 1999 to June 2000 in experimental ponds. Although macrophyte architecture explained some variation in macroinvertebrate abundance between the two macrophytes, most variation was explained by the sampling months. Total number of macroinvertebrates was found to be positively correlated with epiphyton biomass which differed significantly between the two plant types and among sampling months. Taxa richness did not vary between the two plant types. Chironomid larvae were the most abundant organisms and dominated by Apedilum elachistus on both plant communities. Annual production of five chironomid species was estimated by the size-frequency method. Production estimates (P) in g dry wt m-2 yr-1 of plant surface area for the predator Tanypodinae larvae were: Larsia decolarata, P= 0.77 and 0.67, Labrundinia virescens, P= 0.59 and 0.35 on M. spicatum and H. dubia, respectively. Larvae of Cricotopus sylvestris and Psectrocladius vernalis were collected from M. spicatum from March to mid-June. Production of C. sylvestris was found to be 0.46 g dry wt m-2, whereas it was 0.07 g dry wt m-2 for P. vernalis for this period. Apedilum elachistus exhibited the highest productivity: 9.9 g dry wt m-2 …

Redefining Beauty
In an effort to continue the conceptual and aesthetic growth started in graduate school, I have produced a body of work dealing with the relation between the fragmentation of the figure and the self-perception of beauty. I produced twelve prints that have been exhibited at Cora Stafford Gallery. I have analyzed the body of work conceptually and formally and chose to discuss six pieces in a problem- in lieu-of-thesis. My work and book references informed the content of the paper. I divided it into three chapters; Introduction, Description of the Work, and the Conclusion. Within the body of the paper the paragraphs are sectioned into descriptions, methodology and intent of the six pieces. I went into detail of the process and content and addressed the questions posted in the Statement of Problem.

London, Ankara, and Geneva: Anglo-Turkish Relations, The Establishment of the Turkish Borders, and the League of Nations, 1919-1939
Access:
Use of this item is restricted to the UNT Community
This dissertation asserts the British primacy in the deliberations of the League of Nations Council between the two world wars of the twentieth century. It maintains that it was British imperial policy rather than any other consideration that ultimately carried the day in these deliberations. Given, as examples of this paramountcy, are the discussions around the finalization of the borders of the new republic of Turkey, which was created following the collapse of the Ottoman Empire at the end of the First World War. These discussions focused on three areas, the Mosul Vilayet or the Turco-Iraqi frontier, the Maritza Delta, or the Turco-Greek frontier, and the Sanjak of Alexandretta or the Turco-Syrian frontier.

Family Rituals and Deviant Behavior
Many researchers have sought to identify the antecedents of deviant behavior. The purpose of this study was to explore whether family rituals might contribute to social control, and thereby reduce deviant behavior. Walter Reckless' containment theory provided the theoretical framework for the study. This theory suggests that both inner and outer containment variables control social behavior. It was proposed that meaningful family rituals would contribute to the development of inner and outer containment, and therefore, reduce the number of deviant behaviors committed by the respondents. In this study, the inner containment variable was self-esteem, and the outer containment variables were participation in conforming activities with family members both inside and outside the home, and participation in extracurricular activities. Two hundred and seven incarcerated respondents and 217 college students responded to three survey instruments, the Family Rituals Questionnaire, the Culture Free Self-Esteem Inventory, and a Family Information Inventory. Findings indicated that the college students reported experiencing more meaningful family rituals than the incarcerated respondents. Results indicate that the two groups differed significantly on all of the major variables. However, meaningful family rituals had little association with self-esteem, and self-esteem had no relationship with deviant behavior. Meaningful family rituals did account for …

A Physiological Age-Grading System for Female Hydrellia pakistanae Deonier (Diptera: Ephydridae)
Access:
Use of this item is restricted to the UNT Community
Conflicting opinions about the effectiveness of H. pakistanae as a biological control agent for hydrilla prompt researchers to find a method for assessing the fly's success. Developing a physiological age-grading system for the fly using ovarian morphology to detect changes in reproductive activity is useful for evaluating reproductive status of the fly in field populations. Changes in the appearance of follicular relics in ovaries with oviposition provide a reliable method to estimate fecundity. Characteristics of follicular relics were used to develop a system with eight physiological age classes, three nulliparous and five parous. Changes that occur in the fat body were used to assist in classification of nulliparous females or those with low egg counts.

Access:
Use of this item is restricted to the UNT Community
Neuringer, Deiss, and Olson (2000) was replicated and extended to determine the effect of variability contingencies on task acquisition for twelve 7-9 year old children. Subjects first learned to press a computer's shift keys with increasing response variation. Each subject was then exposed to one of three experimental conditions during which they received a point for target responses. Variability condition subjects received additional points on a variable interval schedule for nontarget responses occurring less than 3% of the time. The any condition subjects received additional points on a variable interval schedule for any nontarget response. Control subjects received points only for target responses. All variability condition and two control subjects learned the target response. All any condition subjects and two control subjects did not.

Intrinsic Religious Orientation and Mental Health in Later Life
This dissertation research project was conducted to investigate religion as a coping resource in later life. The major proposition of the study was that intrinsic religious orientation is positively associated with mental health in late life. A forty three-item questionnaire was distributed to residents of four independent retirement communities resulting in a sixty-six percent return rate. The convenience sample of 214 individuals, with a mean age of 81.94 years, consisted of 156 female and 58 male respondents. Intrinsic religious orientation was held as the independent variable, while mental health was the dependent variable. Stress vulnerability characteristics were held as control variables including age, gender, education, stressful life events, marital status, perceived social support, and physical health. The zero order correlation between the independent and dependent variables was r = .128, sig. = .034 (1 tailed). When all control variables were entered, the relationship between intrinsic religious orientation and mental remained, r = .116, sig. = 046 (1 tailed). Regression analysis produced three predictors of mental health for females: stressful life events, age, and intrinsic religious orientation. Intrinsic religious orientation did not significantly change the relationship between stressful life events and mental health. A highly narrow variability in the sample limited …

Investigations of Thermochemistry and the Kinetics of H Atom Radical Reactions
Access:
Use of this item is restricted to the UNT Community
The thermochemistry of several species, and the kinetics of various H atom radical reactions relevant to atmospheric and combustion chemistry were investigated using ab initio theoretical techniques and the flash photolysis / resonance fluorescence technique. Using ab initio quantum mechanical calculations up to the G3 level of theory, the C-H bond strengths of several alkanes were calculated. The bond strengths were calculated using two working reactions. From the results, it is apparent that the bond strengths decrease as methyl groups are added to the central carbon. The results are in good agreement with recent experimental halogenation kinetic studies. Hydrogen bond strengths with sulfur and oxygen were studied via CCSD(T) theory, together with extrapolation to the complete basis set limit. The results for the bond dissociation energies (ground state at 0 K, units: kJ mol-1) are: S-H = 349.9, S-D = 354.7, HS-H = 376.2, DS-D = 383.4, and HO-H = 492.6. These data compare well with experimental literature. The rate constants for the isotopic reactions of H + H2S, D + H2S, H + D2S, and D + D2S are studied at the QCISD(T)/6-311+G(3df,2p) level of theory. The contributions of the exchange reaction versus abstraction are examined through transition state …

Wisdom and Law: Political Thought in Shakespeare's Comedies
Access:
Use of this item is restricted to the UNT Community
In this study of A Midsummer Night's Dream, The Merchant of Venice, and Measure for Measure I argue that the surface plots of these comedies point us to a philosophic understanding seldom discussed in either contemporary public discourse or in Shakespearean scholarship. The comedies usually involve questions arising from the conflict between the enforcement of law (whether just or not) and the private longings (whether noble or base) of citizens whose yearnings for happiness tend to be sub- or even supra-political. No regime, it appears, is able to respond to the whole variety of circumstances that it may be called upon to judge. Even the best written laws meet with occasional exceptions and these ulterior instances must be judged by something other than a legal code. When these extra-legal instances do arise, political communities become aware of their reliance on a kind of political judgment that is usually unnoticed in the day-to-day affairs of public life. Further, it is evident that the characters who are able to exercise this political judgment, are the very characters whose presence averts a potentially tragic situation and makes a comedy possible. By presenting examples of how moral and political problems are dealt with by …

Automatic Software Test Data Generation
Access:
Use of this item is restricted to the UNT Community
In software testing, it is often desirable to find test inputs that exercise specific program features. Finding these inputs manually, is extremely time consuming, especially, when the software being tested is complex. Therefore, there have been numerous attempts automate this process. Random test data generation consists of generating test inputs at random, in the hope that they will exercise the desired software features. Often the desired inputs must satisfy complex constraints, and this makes a random approach seem unlikely to succeed. In contrast, combinatorial optimization techniques, such as those using genetic algorithms, are meant to solve difficult problems involving simultaneous satisfaction of many constraints.

Nature By Design

Organic forms representing nature, but not particular species, are combined with elements signifying attitudes toward the natural world with an emphasis on North American culture. The viewer is encouraged to consider human effects on the environment. Aquarium Night Light and Trophy both refer to the human tendency for commercial exploitation coupled with the creation of nature images we sometimes seem to prefer over the reality of the natural world. Reliquary metaphorically connects traditional religious connotations associated with saints' relics to both a biblical injunction to use anything we needed from the natural world and our contemporary belief that exposure to nature can have beneficial effects on human mental, spiritual, and physical health.

Discovering the Parameters of a Successful Piece: While Developing a Body of Work that Represents My Passion for Clay and My Enthusiasm for Life
Access:
Use of this item is restricted to the UNT Community
Chapter I describes the purpose of the project, which was to develop a body of work that exhibits all that I am at this point in time. The questions I presented to myself were the following: 1. A successful piece is defined by what parameters? 2. What visual qualities indicate my passion for clay and my enthusiasm for life? Chapter II lists and explains the five parameters of a successful piece, which are composition, firing, mark making, color contrast, and movement. Furthermore there is an explanation on how these parameters visually display my passion for clay and my enthusiasm for life. Chapter III is a summary concluding that by discovering my five parameters of a successful piece I now understand the elements that I am searching for in my work. My work will grow from this understanding as long as I have the same passion for clay and enthusiasm for life.
