Layered Double Hydroxides: Synthesis, Characterization, and Interaction of Mg-Al Systems with Intercalated Tetracyanonickelate(II)
The square-planar tetracyanonickelate(II) anion was intercalated into 2:1 and 3:1 Mg-Al layered double hydroxide systems (LDHs). In the 2:1 material, the anion holds itself at an angle of about 30° to the layers, whereas in the 3:1 material it lies more or less parallel to the layers. This is confirmed by orientation effects in the infrared spectra of the intercalated materials and by X-ray diffraction (XRD) data. The measured basal spacings for the intercalated LDH hosts are approximately 11 Å for the 2:1 and approximately 8 Å for the 3:1. The IR of the 2:1 material shows a slight splitting in the ν(CN) peak, which is suppressed in that compound's oriented IR spectrum, indicating that at least some of the intercalated anion's polarization is along the z-axis. This effect is not seen in the 3:1 material. A comparison between chloride LDHs and nitrate LDHs was made with respect to intercalation of tetracyanonickelate(II) anions. Both XRD data and atomic absorption spectroscopy (AAS) data of the LDH tetracyanonickelates confirms that there are no significant differences between the products from the two types of starting materials. The presence of a weak ν(NO) peak in the IR spectra of those samples made from nitrate …

Needs of familial caregivers of cancer patients across the advanced cancer disease trajectory.
Familial caregivers are providing increasing amounts of care to advanced cancer patients. Increased understanding of caregivers' needs is vital in providing necessary support to lessen caregiver burden and comorbidity. This study examines particular information needs across a variety of specific events in the advanced cancer disease trajectory. A cross-sectional sample of 107 familial caregivers (24 current and 83 bereaved) of people with advanced cancer completed a needs assessment survey along with a measure of health information-seeking behavior. Analyses extend current research by including more specific disease-related events along the advanced cancer trajectory through bereavement. In all information categories, endorsement of wanted information differed across broad stages of Cancer Progression, Treatment, End of Life, and Post-Patient Death. For all information categories, except Dying and Spirituality, greatest information was wanted at the Cancer Progression stage. Information need also differed across specific events within broad stages. The categories of Disease/Medical and Relating to the Patient were the most endorsed at events involving patient care. Spirituality was least endorsed. At patient death, Caregiver Well-being has the highest endorsement. For events thereafter, information on Caregiver Well-being, Spirituality, Future Outlook, and Family and Close Others was most endorsed. Information needs did not differ based on age …

Samuel Richardson's Revisions to Pamela (1740, 1801)
The edition of Pamela a person reads will affect his or her perception of Pamela's ascent into aristocratic society. Richardson's revisions to the fourteenth edition of Pamela, published posthumously in 1801, change Pamela's character from the 1740 first edition in such a way as to make her social climb more believable to readers outside the novel and to "readers" inside the novel. Pamela alters her language, her actions, and her role in the household by the end of the first edition; in the fourteenth edition, however, she changes in little more than her title. Pamela might begin as a novel that threatens the fabric of class hierarchies, but it ends-both within the plot and externally throughout its many editions-as a novel that stabilizes and strengthens social norms.

Towards European Integration: Do the European Union and Its Members Abide by the Same Principles?
In the last few decades the European Union (EU) and its members have emphasized the importance of human rights and the need to improve human rights conditions in Third World countries. In this research project, I attempted to find out whether the European Union and its members practice what they preach by giving precedence to countries that respect human rights through their Official Development Assistance (ODA) program. Furthermore, I tried to analyze whether European integration occurs at the foreign policy level through aid allocation. Based on the literatures on political conditionality and on the relationship between human rights and foreign aid allocation, I expected that all EU members promote principles of good governance by rewarding countries that protect the human rights of their citizens. I conducted a cross-sectional time-series selection model over all recipients of ODA for each of the twelve members for which I have data, the European Commission, and the aggregate EU disbursements from 1979 to 1998.

Maladaptive appraisals and intrusive thoughts associated with obsessive compulsive disorder: A semiidiographic approach.
This project investigated the metacognitive strategies used to appraise obsessive thoughts employed by individuals with different anxiety symptoms. Two hundred eighty-seven undergraduate students completed two repertory grids and three anxiety scales. The repertory grids respectively examined the appraisal process of intrusive thoughts both from the perspective of the rater and the rater's imagined average person. Variables quantified from the rep grid related to the construal process of raters' own intrusions, failed to demonstrate robust differences between OCD, non-OCD anxious, and non-anxious individuals. However, it appears that anxious individuals, not just those with OCD, use metacognitive strategies to suppress rigid constructions under perceived social evaluation. Future studies may wish to use related grid variables to explore the relation between obsessions and social anxiety.

Impact of Texas Counselors' Network on students: A preliminary study.
This study assessed the impact of the Texas Counselors' Network (TCN) on students of counselors who attended TCN workshops. TCN is a professional organization created in 1996 for the professional development of counselors. TCN impacts primary and secondary school students by providing counselors with selected skills to assist them in helping students. In theory, TCN thus impacts these students by improving overall skills of participating counselors. This study assessed the progress of students before and after implementation of TCN. Students' progress was considered in four areas: Texas Accountability Assessment Scores (TAAS), attendance rates, dropout rates, and high school student enrollment in technical programs. The current study compared student performance in the above four areas during a two to three year period prior to the establishment of TCN, with the initial six years of TCN existence. This study examined data attained through the Texas Educational Agency (TEA) Website using their Academic Excellence Indicator System (AEIS) for four regional TCN groups. The study used a paired t-test to compare the performance of students before versus after counselor participation in network workshops. The findings indicated that overall, counselor participation in TCN could have a significant effect on student performance. In fact, eight tests …

Microfarms
This study describes the role of rural women and their importance in the success of microfarm projects. Microfarm cultivators can increase their income levels through trade of agricultural products. By adopting self-sustaining methods, the cultivator saves money and does not need to rely as much on goods and services from outside resources to increase food production efficiencies in microfarms. This goal can be reached in part through careful planning and construction of the microfarm facility. In addition, in developing phases of the microfarm, the external resources may possibly be a mechanism to increase expansion and knowledge. Microfarms are an important option for the third world countries and poor people worldwide.

Internet Use Among African American College Students: Psychosocial Correlates of the Digital Divide
An exploratory study was conducted examining Internet usage among African-American college students. The study examined both psychosocial correlates, including technological anxiety and racial identity as well as socioeconomic measures, as they impacted Internet usage. Additionally, three distinct measures of Internet usage, thin access, thick access and the Internet Connectedness Index (ICI), were used as criterion variables in three separate multiple regression analysis (MRA) models. The results of the study found differences in predictive validity based on the criterion variable used, with the ICI accounting for the greatest amount of variance (54%). Racial identity, in terms of internal beliefs and feelings about being African American and internalization of Afrocentric values in a political context were found to be predictive of Internet usage as measured by the ICI.

Development and Psychometric Validation of the State-Trait Spirituality Inventory
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 …

The Naturalist
The Naturalist is a collection of poems with a critical preface. In this preface, titled "'Death is the mother of beauty': The Contemporary Elegy and the Search for the Dead," I examine contemporary alterations and manifestations of the traditional genre of elegy. I explore the idea that the contemporary mourner is aware of the need to search for meaning despite living in a world without a centrally believed mythology. This search exposes the mourner's need to remain connected to the dead and, by proxy, to grace. I conclude that the contemporary elegy, through metaphorical figuration, personal memory, and traditional symbolism, simultaneously employs and denies the traditional elegiac conventions of apotheosis and resurrection by reconceiving them as methods not of achieving transcendence but of embracing desire with an acceptance of the inability to transcend. The poems of The Naturalist are a collection of elegies that reflect many of the ideas brought forth in the preface.

Crazy People
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.

Multiple-Respondent Anecdotal Assessments for Behavior Disorders: An Analysis of Interrater Agreement and Correspondence With Functional Analysis Outcomes
An analysis of interrater agreement across multiple respondents on anecdotal assessments and correspondence between functional analysis outcomes was completed. Experiment I evaluated overall agreement among multiple respondents (direct-care staff) on the hypothesized function of each residents (28 adults with mental retardation) problematic behavior using the Motivational Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST). Results of the questionnaires indicated that respondents agreed on the function of the problematic behavior for 10 of the 28 residents. Experiment II examined whether, for selected cases in which 4 out of 5 respondents agreed on the function of the problematic behavior, correspondence occurred between functional analyses and anecdotal assessments outcomes. Two of the 6 functional analyses did not evoke the problematic behavior. However, 4 functional analyses did produce corresponding outcomes suggesting that, when the functional analyses produced interpretable data, the results of the functional analyses corresponded with those of the anecdotal assessments.

Social Support, Depression, and Cardiovascular Disease in Married, Middle-Aged/Older Adults
This study examined the relationship between physical health, social support, and depression in a married, middle-aged/older adult sample in which at least one partner has heart disease. The data was obtained from a national longitudinal study the Health and Retirement Survey (HRS) and is composed of selected respondents and their spouses. The HRS Wave 1 data that was used for these analyses was collected in 1992 and 1993. This study tested a stress buffer model predicting the relationship between physical health, social support, and depression. For study inclusion, participants must have been diagnosed with cardiovascular disease and received treatment in the last year. A heart disease construct was developed by calculating the level of disease by the number of conditions and medical treatments received within the last year. A second health category for other chronic health conditions included diabetes, arthritis, cancer, and chronic pain. These constructs were combined into a total disease construct, which provided a broad measure of health problems typical of an older adult population. Social support was determined by respondents' satisfaction with friends, neighbors, family, their marriage, and enjoyable time spent with their spouse. Social support was subdivided into two constructs separating spousal support from social support …

Symphonic Fantasia Han-Kook Oui Ja-Yeon (Nature in Korea): Score and Critical Commentary
The Symphonic Fantasia Han-Kook oui Ja-Yeon (Nature in Korea ) is a single-movement orchestral piece, which is divided into 5 characteristic sections - each section has programmatic subtitles (Rocks, River, Sea, Wind, and Mountain) and its own idée fixe motive. The degree of texture (homophonic/polyphonic), dynamics (strong/weak), density (thick/thin), velocity (fast/slow), and orchestration (emphasizing various sections of the orchestra) is determined by depiction of the subtitles. The critical commentary of the Symphonic Fantasia Han-Kook oui Ja-Yeon (Nature in Korea ) includes a discussion of form, pitch content (melodic and harmonic), and texture of the piece. The commentary also includes a discussion of the use of programmatic subtitles (Rocks, River, Sea, Wind, and Mountain) and depiction of these concepts in the orchestration of the work. A comparison with other orchestral works is added for explanation and support of the composer's concept. Some of the other composers who are discussed in this paper include Richard Strauss (Alpine Symphony), Gustav Holst (The Planets), Frank Bridge (The Sea), Aaron Copland (Billy the Kid), and Joseph Klein (Pathways: Interior Shadows).

Appellate Recruitment Patterns in the Higher British Judiciary: 1850 - 1990
This study seeks to advance the understanding of appellate promotion in the senior judiciary of Great Britain . It describes the population and attributes of judges who served in the British High Courts, Court of Appeal, and Appellate Committee of the House of Lords (i.e., Law Lords) from 1850 to 1990. It specifically builds upon the work of C. Neal Tate and tests his model of appellate recruitment on a larger and augmented database. The study determines that family status, previously asserted as having a large effect on recruitment to the appellate courts, is not as important as previously believed. It concludes that merit effects, professional norms, and institutional constraints offer equally satisfactory or better explanations of appellate recruitment patterns.

Reconstructing Convention: Ensemble Forms in the Operas of Jules Massenet
Over the last quarter-century, scholars have taken a unified approach in discussing form in Italian and French opera of the nineteenth century. This approach centers around the four-part aria and duet form begun by Bellini, codified by Rossini, modified by Verdi, and dissolved by Puccini. A similar trajectory can be seen in French opera in the works of Meyerbeer, Gounod, and Massenet; however, only Meyerbeer and Gounod have received significant critical attention. This is in part due to Massenet's reception as a "composer for the people," a title ill fitting and ripe for reconsideration. This dissertation will examine duet forms in Massenet's oeuvre and will focus on the gradual change in style manifest in his twenty-five operas. Massenet's output can be divided into three distinct periods delineated by his approach to form. Representative works from each period will show how he inherited, interpreted, thwarted, and ultimately rewrote the standard formal conventions of his time and in doing so, created a dramaturgical approach to opera that unified the formerly separate number-based elements. Massenet's longevity and popular appeal make him the quintessential French opera composer of the fin de siècle and the natural choice for examining reconstructed conventions.

Selected Lute Music from Paris, Rés. Vmd. Ms. 27 from the Bibliothèque Nationale: Reconstruction, Edition, and Commentary
Access:
Use of this item is restricted to the UNT Community
Paris . Rés. Vmd. Ms. 27, known as Tl.1, or the Thibault Manuscript, is one of the earliest extant sources of lute music, containing twenty-four solos and eighty-six accompaniments for vocal compositions. The manuscript was copied in Italian lute tablature lacking rhythm signs, which makes it inaccessible for modern performance. Each selection contains a full score of the four-part vocal concordance, and the reconstructed lute part in both the original notation and keyboard transcription. The introductory study elaborates upon the creation dates for Tl.1 (ca. 1502-1512) through its relationship with the sources of the time and with the older unwritten tradition of Italian secular music that is apparent in the formal treatment of the music.

Travel is now the largest online business-to-consumer product in the United States. Online hotel bookings are the second largest segment of online travel. Leisure travelers online spending will increase dramatically from 2002 to 2007. However, a majority of hospitality companies do not currently take advantage of the Internet as the cheapest and most efficient distribution medium. The purpose of this study examined leisure travelers' demographic and psychographic characteristics, online booking and travel frequency that influence travelers' desired hotel Website features and functions. The results found out that demographics (gender, occupation, and ethnicity), and psychographics (travel benefit sought), number of leisure travel trips per year, and number of online hotel bookings per year have impact on hotel Website attribute preferences.

Peptide-based hidden Markov model for peptide fingerprint mapping.
Access:
Use of this item is restricted to the UNT Community
Peptide mass fingerprinting (PMF) was the first automated method for protein identification in proteomics, and it remains in common usage today because of its simplicity and the low equipment costs for generating fingerprints. However, one of the problems with PMF is its limited specificity and sensitivity in protein identification. Here I present a method that shows potential to significantly enhance the accuracy of peptide mass fingerprinting, using a machine learning approach based on a hidden Markov model (HMM). This method is applied to improve differentiation of real protein matches from those that occur by chance. The system was trained using 300 examples of combined real and false-positive protein identification results, and 10-fold cross-validation applied to assess model discrimination. The model can achieve 93% accuracy in distinguishing correct and real protein identification results versus false-positive matches. The receiver operating characteristic (ROC) curve area for the best model was 0.833.

Police Officer Burnout: An Examination of Officer Stress, the Policing Subculture and the Advantages of Family Counseling
Access:
Use of this item is restricted to the UNT Community
The work of a police officer is stressful and could potentially lead to burnout. As a result, a variety of reactions may occur which include, cynicism, abuse of authority, and in extreme cases suicide. One method which has been proven to be effective in treating officer stress is counseling; however, because of the policing subculture the opportunity to seek counseling has been ignored. In order to successfully manage officer stress, the subculture must be dealt with. Additionally, the officers' family must also be acknowledged as being affected by officer burnout. Counseling services must be made available to the officer's family and through training they can become a source of support instead of an added source of stress to the officer.

The Anatomy of Academic Dishonesty: Cognitive Development, Self-Concept, Neutralization Techniques, and Attitudes Toward Cheating
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 …

An Analysis of Adler's Theory and the Female Criminal
This research paper addressed the following question: Do select case studies conform to Dr. Freda Adler's theory regarding socio-economic influences on female criminal behavior or dispute her theory? My research involved three female criminals: Karla Faye Tucker, Andrea Yates, and Susan Smith. I addressed Adler's theory in detail, other theories, the makeup of the female criminal and various female crimes. This study provided evidence that all three case studies conform to Adler's theory. nIn accordance with Adler's theory, each of these three females committed crimes of accessibility. None of the three individuals sought to commit a premeditated act or to murder unknown victims. They were motivated by emotions arising at a point in time when access/opportunity presented itself.
