Prior to the development of interactive television, schools that were either geographically isolated or financially restricted were often unable to provide courses that may have been essential for students. Interactive television has helped such school districts provide appropriate courses for their students. Because student self-efficacy is a significant indicator of student success, the relationship between distance learning and students' self-efficacy requires research. The problem of the study was to examine the impact of site location in a distance learning environment on student self-efficacy in Spanish instruction. The participants in this study were junior high school students enrolled in distance-learning Spanish classes at two junior high schools in a north central Texas independent school district. All of the students were taught by the same instructor. The age range of the students was from 11 to 14 years of age, and all students were in either the seventh or the eighth grade. Students took a modified version of the Motivated Strategies for Learning Questionnaire at the end of each treatment. Using the counterbalanced design, each subject was matched to themselves. T-tests for nonindependent samples were used to compare the two treatments. The findings indicate that there is no significant difference in the …

This study explored the relationship between cheating among university students and their cognitive developmental levels, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating. The purposes of this study were to investigate: (1) The relationships between academic dishonesty and each of the following overall independent variables: cognitive development, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating, and (2) the reasons behind college student academic cheating behaviors. The study used data from anonymous, self-report surveys administered to undergraduate students in-class and at supplemental sessions. Student participation was voluntary. The study was correlational. The five hypotheses were: (1) Self-concept is significantly and negatively related to academic dishonesty; (2) Cognitive development is significantly and negatively related to academic dishonesty; (3) Attitude toward cheating is significantly and negatively related to academic dishonesty; (4) The use of neutralization techniques is significantly and positively related to academic dishonesty; (5) Cognitive development, self-concept, and attitude toward cheating will make significant contributions to the regression model for the dependent variables of academic dishonesty. The data supported the first, third, and fourth hypotheses. However, the second and fifth hypotheses were supported under certain conditions. The roles of cognitive …

This dissertation research explored the capabilities of neuronal networks grown on substrate integrated microelectrode arrays in vitro to be applied to toxicological research and lipid signaling. Chapter 1 details the effects of chlorine on neuronal network spontaneous electrical activity and pharmacological sensitivity. This study demonstrates that neuronal networks can maintain baseline spontaneous activity, and respond normally to pharmacological manipulations in the present of three times the chlorine present in drinking water. The findings suggest that neuronal networks may be used as biological sensors to monitor the quality of water and the presence of novel toxicants that cannot be detected by conventional sensors. Chapter 2 details the neuromodulatory effects of N-acylethanolamides (NAEs) on the spontaneous electrical activity of neuronal networks. NAEs are a group of lipids that can mimic the effects of marijuana and can be derived from a variety of plant sources including soy lecithin. The most prominent NAEs in soy lecithin, palmitoylethanolamide (PEA) and linoleoylethanolamide (LEA), were tested individually and were found to significantly inhibit neuronal spiking and bursting activity. These effects were potentiated by a mixture of NAEs as found in a HPLC enriched fraction from soy lecithin. Cannabinoid receptor-1 (CB1-R) antagonists and other cannabinoid pathway modulators indicated …

Engelbert Humperdinck (1854-1921), who was considered a Wagnerian due to to his past work in Bayreuth and the Wagnerian traits of his Hänsel und Gretel, seems to have believed that to define himself as a composer, he had to engage somehow with that designation, whether through orthodox Wagner imitation or an assertion of his independence from Wagner's musical legacy. The latter kind of engagement can be seen in Humperdinck's Königskinder (1897), in which he developed a new kind of declamatory notation within the context of melodrama, thus fulfilling Wagnerian ideals as well as progressing beyond them. The effectiveness of Humperdinck's effort is seen in the ensuing critical reception, in which the realities of being heard as a Wagnerian composer are clarified.

Claremont Connections is a collection of fictional short stories about the relationships between the generations of women in one family and their friends.

Research on the adoption of innovation is largely limited to factors affecting immediate change with few studies focusing on enduring or lasting change. The purpose of the study was to examine the personality characteristics of cognitive playfulness, innovativeness, and essentialness beliefs in educators who were able to make an enduring change in pedagogy based on the use of technology in the curriculum within their assigned classroom settings. The study utilized teachers from 33 school districts and one private school in Texas who were first-year participants in the Intel® Teach to the Future program. The research design focused on how cognitive playfulness, innovativeness, and essentialness beliefs relate to a sustained high level of information technology use in the classroom. The research questions were: 1) Are individuals who are highly playful more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who are less playful? 2) Are individuals who are highly innovative more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who are less innovative? 3) Are individuals who believe information technology use is critical and indispensable to their …

The Pecan Creek Waste Reclamation Plant in Denton, Texas, an activated sludge WWTP, was sampled monthly for ten months to determine seasonal and site variation in concentrations of triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol), an antibacterial additive. SNK separation after the highly significant ANOVA on ranked data were: summer = fall > winter = spring and influent > downstream = effluent = wetland inflow > wetland outflow (a=0.05). After the plant converted to ultraviolet disinfection, measurements were made before and after the UV basin to determine if significant amounts of triclosan were converted to dioxin. Percent loss at each of the treatment steps was determined. Concentrations of triclosan in the downstream site were below the published NOEC for the most sensitive species.

The pilot study used in this thesis examined the attitudes and perceptions of a small group of students at the University of North Texas. The participants in this pilot study (n=22) were administered an online music file sharing survey, a Defining Issues Test (DIT), and participated in a small focus group. This thesis also outlined the history and progression of online music piracy in the United States, and addressed four research questions which aimed to determine why individuals choose to engage in the file sharing of copyrighted music online.

Assessing offenders' risk of future violent behavior continues to be an important yet controversial role of forensic psychologists. A key debate is the relative effectiveness of assessment methods. Specifically, actuarial methods (see Quinsey et al., 1998 for a review) have been compared and contrasted to clinical and structured clinical methods (see e.g. Hart, 1998; Webster et al., 1997). Proponents of each approach argue for its superiority, yet validity studies have made few formal comparisons. In advancing the available research, the present study examines systematically the type of forensic case (i.e., sexual violence versus nonsexual violence) and type of assessment method (i.e., actuarial, structured clinical, and unstructured clinical). As observed by Borum, Otto, and Golding (1993), forensic decision making can also be influenced by the presence of certain extraneous clinical data. To address these issues, psychologists and doctoral students attending the American Psychology Law Society conference were asked to make several ratings regarding the likelihood of future sexual and nonsexual violence based on data derived from actual defendants with known outcomes. Using a mixed factorial design, each of these assessment methods were investigated for its influence on decision-makers regarding likelihood of future violence and sexually violent predator commitments. Finally, the potentially …

Crazy People, a collection of short stories, presents characters and their various psychological crutches. The preface explores the concept of negative space as it applies to short fiction, manifesting itself in the form of open-ended endings, miscommunication between characters, rhetorical questions, and allusions to unspecified characters. The preface seeks to differentiate "good" space from "bad" space by citing examples from the author's own work, as well as the works of Raymond Carver, Dan Chaon, and Stanley Fish.

The purpose of this study was to describe the implementation, structure, content and outcome of an art-centered unit developed for 5th grade students. This unit was designed to be an example/model of specific tools and procedures that teachers can use in the art and general classroom to promote critical cultural consciousness, which is the ability to analyze both the covert and overt elements of a culture with the purpose of developing a holistic viewpoint that values the cultural heritages of self and others. The participants selected for this study were all the students in three 5th grade classes. The art-centered unit focused on three artists-Romare Bearden, Elizabeth Catlett and Charles White-under the theme "Respect and Homage." The research methods used in this investigation were qualitative. This study was written in a style that described the research design with its origins, organization and implementation. The implementation of the curricular unit developed for this study took place in the art and general classroom. Of particular interest in this study was the framework and structure of the art-centered unit, designed around two specific strategies utilized to promote critical cultural consciousness. One strategy in this unit was the identification of art-related or art-centered micro-cultures …

Researchers have studied adolescent bullying behavior since the 1970s, however, today's technological advances have opened the door to a new form of abuse. Teens can no longer escape the wrath of their bullies once they have left the school grounds, because bullies are following them home. Cyberbullying is a new phenomenon in which bullies use computer-mediated communication (CMC) to torment their victims. This research project focused on uncovering some of the mysteries surrounding this new means of bullying. A grounded theory analysis of stories written by victims revealed cyberbullies often use synchronous chat tools, e-mail, web sites, and cell phone text messages to reach their victims. Data analysis also revealed victims use of contextualization, descriptions of their bullying episodes, and discussions of their responses and outcomes to characterize their experiences. Interestingly, the researcher found victims of cyberbullying generally were also victims off face-to-face bullying as well.

Informed by the methodology utilized in Peter Williams's Houses of God: Region, Religion, and Architecture in the United States (1997), the thesis examines Mark Lemmon's Gothic Revival design for the Highland Park Presbyterian Church (1941) with special attention to the denomination and social class of the congregation and the architectural style of the church. Beginning with the notion that Lemmon's church is more complex than an expression of the Southern cultural region defined by Williams, the thesis presents the opportunity to examine the church in the context of the unique cultural region of the city of Dallas. Church archival material supports the argument that the congregation deliberately sought to identify with both the forms and ideology of the late nineteenth-century Gothic Revival in the northeastern United States, a result of the influence of Dallas's cultural region.

This qualitative study examined whether a connection exists between children with emotional disorders consumption of traditional entertainment media and their subsequent vegative/anti-social classroom behavior. Research participants included six first-grade children diagnosed with an emotional disorder and their teacher. They were interviewed using a semi-structured approach. The students were observed in the natural setting of their classroom for a total of twenty-four hours, over a four-day period. Transcripts and classroom observations were analyzed, looking for connections between behavior and consumption of traditional entertainment media. Findings from this study concluded that these students used traditional entertainment media as a method of temporally escaping from the environment of their respective households.

Wear is an important phenomenon that occurs in all the polymer applications in one form or the other. However, important links between materials properties and wear remain illusive. Thus optimization of material properties requires proper understanding of polymer properties. Studies to date have typically lacked systematic approach to all polymers and wear test developed are specific to some polymer classes. In this thesis, different classes of polymers are selected and an attempt is made to use multiple scratch test to define wear and to create a universal test procedure that can be employed to most of the polymers. In each of the materials studied, the scratch penetration depth s reaches a constant value after certain number of scratches depending upon the polymer and its properties. Variations in test parameters like load and speed are also studied in detail to understand the behavior of polymers and under different conditions. Apart from polystyrene, all the other polymers studied under multiple scratch test reached asymptotes at different scratch numbers.

The present study contributes to the widening body of spirituality research by conceptualizing it as a state-trait construct. A new measure of spirituality, the State-Trait Spirituality Inventory (STSI), was created and validated according to psychometric methods of test construction. In its current form, the STSI contains seven state spirituality items and six trait spirituality items. A thorough review of the literature identified common themes in spirituality definitions and assisted in developing definitions of trait and state spirituality. Internal consistency for the trait scale was .88 and for the state scale, .68. Good test-retest reliability was found with coefficients of .84 for trait spirituality and .81 for state spirituality. Results from a preliminary undergraduate sample as well as from the validation sample yielded a two-factor solution. In general, items determined by expert panels as trait items loaded on one factor and items deemed to be state items loaded on the second factor. Multitrait multimethod analysis yielded mixed findings for convergent, divergent, and concurrent validity for the spirituality and religiosity traits. Methods consisted of paper-and-pencil cognitive and behavioral measures. Cognitive measures were more likely to support convergent/divergent validity than were behavioral measures. A major emphasis in the study was to determine whether …

Recent commercial developments have created a need for alternative materials and methods for imparting oil/grease resistance to paper and/or paperboard used in packaging. The performance of a novel grease resistant functional coating comprised of polyvinyl alcohol (PVA), sodium tetraborate pentahydrate (borate) and acetonedicarboxylic acid (ACDA) and the application of said coating by means of flexographic press is presented herein. Application criteria is developed, testing procedures described, and performance assessment of the developed coating materials are made. SEM images along with contact angle data suggest that coating performance is probably attributable to decreased mean pore size in conjunction with a slightly increased surface contact angle facilitated by crosslinking of PVA molecules by both borate ions and ACDA.

Examined in this hermeneutic phenomenological study is a transformation in the researcher's choral music teaching in which students' abilities to construct self emerged organically from interactions, or dialogues, that took place among and between the students, the teacher, and the music being studied. To allow for such interaction to emerge organically and meaningfully, students and teacher both shared in the power needed to construct a classroom environment in which the localized issues of the classroom and the specific contexts of students' lived histories were maintained and encouraged. This process of interaction, based upon dialogue among and between equal agents in the classroom, is described in the study as dialogic interactionism. In order to examine the concept of dialogic interactionism, three constructs upon which dialogic interactionism is based were developed and philosophically analyzed. They include the construction of self through the construction of self-knowledge; the localized reference system of the classroom, and the issue of power. Each construct is considered within the context of extant writings both in general education and music education philosophy. Following the analysis, a theoretical description of the dialogic interactive choral classroom is given as well a description of how such ideas might be realized in practice. …

Parents' perceptions of their child's behavior may differ for mothers and fathers. Differences in parental perception may also be apparent in cases of special needs adoptive families with high demands of their child for time, interventions and attention. This paper examines the differences in mother-child and father-child interactions, child behavior as reported by mothers, and fathers and changes in both after participation in an intervention program. Results suggest notable differences between mothers' and fathers' parent-child interaction scores and reports of child behavior. In addition, interaction scores and behavior reports showed some correlations. Finally, there seemed to be notable differences in the trends for the Child Behavior Checklist compared to the two attachment measures (Randolph Attachment Disorder Questionnaire and Beech Brook Attachment Disorder Checklist). Several possible explanations for mother and father differences are discussed.

"Distance" and Other Stories is a collection of four short stories and a novella that explore the themes of isolation and personal revelation. The dissertation opens with a preface which describes my background as a writer and the forces that shape my work, including science fiction, technology and the internet, cultural marginalization, and Joseph Campbell's hero's motif.

This dissertation argues that the four writers named above use the grotesque to illustrate the increasingly peculiar consequences of the assault of modernity on traditional Southern culture. The basic conflict between the views of Bakhtin and Kayser provides the foundation for defining the grotesque herein, and Geoffrey Harpham's concept of "margins" helps to define interior and exterior areas for the discussion. Chapter 1 lays a foundation for why the South is different from other regions of America, emphasizing the influences of Anglo-Saxon culture and traditions brought to these shores by the English gentlemen who settled the earliest tidewater colonies as well as the later influx of Scots-Irish immigrants (the Celtic-Southern thesis) who settled the Piedmont and mountain regions. This chapter also notes that part of the South's peculiarity derives from the cultural conflicts inherent between these two groups. Chapters 2 through 5 analyze selected short fiction from each of these respective authors and offer readings that explain how the grotesque relates to the drastic social changes taking place over the half-century represented by these authors. Chapter 6 offers an evaluation of how and why such traditions might be preserved. The overall argument suggests that traditional Southern culture grows out of …

Countries with rich natural resource endowments suffer from lower economic growth and various other ills. This work tests whether the resource curse also extends to the quality of regulation and the level of corruption. A theoretical framework is developed that informs the specification of interactive random effects models. A cross-national panel data set is used to estimate these models. Due to multicollinearity, only an effect of metals and ores exports on corruption can be discerned. Marginal effects computations show that whether nature corrupts or not crucially depends on a country's institutions. A broad tax base and high levels of education appear to serve as inoculations for countries against the side-effects of mineral wealth.

This research addressed two main issues that have become evident in studies of interstate cooperation. The first issue has to do with the relationship between cooperation and conflict. Can they be represented on a single, uni-dimensional continuum, or are they better represented by two theoretically and empirically separable dimensions? Granger causality tests were able to clarify the nature of cooperative events. The second issue is related to factors that might facilitate or discourage cooperation with other countries as a foreign policy tool. Factors used to explain cooperation and conflict include domestic variables, which have not been fully accounted for in previous empirical analyses. It is hypothesized that economic variables, such as inflation rates, GDP, and manufacturing production indices affect the likelihood of cooperative event occurrences. The effect of political dynamics, such as electoral cycles, support rates and national capability status, can also affect the possibility of cooperative foreign policies. The domestic factors in panel data was tested with Feasible Generalized Least Square (FGLS) in order to take care of heteroscedasticity and autocorrelations in residuals. The individual case analysis used linear time series analysis.
