An investigation of the relationships between job characteristics, satisfaction, and team commitment as influenced by organization-based self-esteem within a team-based environment

Access: Use of this item is restricted to the UNT Community
Team-based management is a popular contemporary method of redesigning jobs in order to more effectively utilize the human potential of employees. The use of such management techniques should result in increased satisfaction and team commitment; however, many research studies have failed to demonstrate increases in affective outcomes on the part of the employee. The research question examined in this study is, "What specific job dimensions and situational factors result in higher levels of satisfaction and team commitment?" The Job Characteristics Model (Hackman & Oldham, 1975) provided a basis for this study. The model was designed for individual contributors and has not been extensively used in team research. As expected it was found that within a team-based environment higher levels of the five core job dimensions of skill variety, task identity, task significance, autonomy, and job feedback were associated with increased satisfaction and team commitment. Organization-based self-esteem was found to mediate the relationship between the five core job dimensions and the affective outcome variables. Contrary to expectations, however, it was found that consultative team members experienced higher levels of satisfaction and commitment than substantive team members. In addition, consultative team members reported higher levels of two core job dimensions, skill variety …

Emotional Health, Well-Being, And Religion as Quest

Access: Use of this item is restricted to the UNT Community
This study examined the relationship between the religious orientation quest and well-being using the 1998 General Social Survey. In addition to the religious orientation quest the extrinsic and intrinsic religious orientations were also investigated. Analysis of the data indicated that there was a slight negative association between quest and general well-being, while also demonstrating a strong positive association between quest and inner peace. These results underscore the supposition that quest is an orientation that is complex and ultimately deserves further attention.

Iconoclast in the mirror.

Access: Use of this item is restricted to the UNT Community
This work explores identity positions of speakers in modern and contemporary poetry with respect to themes of subjectivity, self-awareness, lyricism, heteroglossia, and social contextualization, from perspectives including Bakhtinian, queer, feminist and postructuralist theories, and Peircian semiotics. Tony Hoagland, W.H. Auden, Adrienne Rich, and the poetic prose of Hélène Cixous provide textual examples of an evolving aesthetic in which the poet's self and world comprise multiple dynamic, open relationships supplanting one in which simple correspondences between signifiers and signifieds define selves isolated from the world. Hypertext and polyamory serve as useful analogies to the semantic eros characteristic of such poetry, including the collection of original poems that the critical portion of this thesis introduces.

A Comparison of Five Robust Regression Methods with Ordinary Least Squares: Relative Efficiency, Bias and Test of the Null Hypothesis

Access: Use of this item is restricted to the UNT Community
A Monte Carlo simulation was used to generate data for a comparison of five robust regression estimation methods with ordinary least squares (OLS) under 36 different outlier data configurations. Two of the robust estimators, Least Absolute Value (LAV) estimation and MM estimation, are commercially available. Three authormodified variations on MM were also included (MM1, MM2, and MM3). Design parameters that were varied include sample size (n=60 and n=180), number of independent predictor variables (2, 3 and 6), outlier density (0%, 5% and 15%) and outlier location (2x,2y s, 8x8y s, 4x,8y s and 8x,4y s). Criteria on which the regression methods were measured are relative efficiency, bias and a test of the null hypothesis. Results indicated that MM2 was the best performing robust estimator on relative efficiency. The best performing estimator on bias was MM1. The best performing regression method on the test of the null hypothesis was MM2. Overall, the MM-type robust regression methods outperformed OLS and LAV on relative efficiency, bias, and the test of the null hypothesis.

Stretched Out on Her Grave: Pathological Attitudes Toward Death in British Fiction 1788-1909

Access: Use of this item is restricted to the UNT Community
Nineteenth-century British fiction is often dismissed as necrophillic or obsessed with death. While the label of necrophilia is an apt description of the fetishistic representations of dead women prevalent at the end of the century, it is too narrow to fit literature produced earlier in the century. This is not to say that abnormal attitudes toward death are only a feature of the late nineteenth century. In fact, pathological attitudes toward death abound in the literature, but the relationship between the deceased and the survivor is not always sexual in nature. Rather, there is a clear shift in attitudes, from the chaste death fantasy, or attraction to the idea of death, prevalent in Gothic works, to the destructive, stagnant mourning visible in mid-century texts, and culminating in the perverse sexualization of dead women at the turn of the century. This literary shift is most likely attributable to the concurrent changes in attitudes toward sex and death. As sex became more acceptable, more public, via the channels of scientific discourse, death became a less acceptable idea. This “denial of death” is a direct reaction to the religious uncertainties brought about by industrialization. As scientists and industrialists uncovered increasing evidence against a …

Stretched Out On Her Grave: The Evolution of a Perversion

Access: Use of this item is restricted to the UNT Community
The word "necrophilia" brings a particular definition readily to mind – that of an act of sexual intercourse with a corpse, probably a female corpse at that. But the definition of the word did not always have this connotation; quite literally the word means "love of the dead," or "a morbid attraction to death." An examination of nineteenth-century literature reveals a gradual change in relationships between the living and the dead, culminating in the sexualized representation of corpses at the close of the century. The works examined for necrophilic content are: Mary Wollstonecraft’s Mary, A Fiction, Mary Shelley’s Frankenstein, Emily Brontë’s Wuthering Heights, and Bram Stoker’s Dracula and The Jewel of Seven Stars.

Barriers Limiting Access to Hospice Care for Elderly African Americans in Amarillo, Texas

Access: Use of this item is restricted to the UNT Community
This study examines barriers limiting access to hospice care for elderly African Americans. Ethnic background plays a critical role in the development of attitudes, beliefs and expectations related to death and issues surrounding hospice care. The purpose of this study was to identify barriers that may limit access to hospice care for African Americans. A questionnaire was administered to 56 elderly African Americans in three religious settings and an African American senior citizens center. The questionnaire was designed to obtain information concerning African Americans' attitudes toward death and dying; religious beliefs; health beliefs; familiarity with hospice and prospective use of hospice. The results of the study indicate a number of barriers in access to hospice care for African Americans including: hospice knowledge barriers; education/outreach barriers; cultural knowledge barriers related to death/dying values; family/social support barriers; hospice organizational/provider barriers; health care organizational/provider barriers; and reimbursement barriers.

Evaluation of virulence in wild type and pyrimidine auxotrophs of Pseudomonas aeruginosa using the eukaryotic model system Caenorhabditis elegans.

Access: Use of this item is restricted to the UNT Community
The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial resistance was also shown to increase. It was hypothesized that starvation induced the DAF pathway, which regulates the transcription of genes involved with the antibacterial defense mechanism. Further research will be conducted to test this theory by performing RNAi experiments for the genes functioning in the antibacterial defense mechanism.

Studies of spin alignment in ferrocenylsilane compounds and in regiospecific oxidation reactions of 1,9-dimethylpentacyclo [5.4.0.02,6.03,10.05,9]undecane-8,11-dione.

Access: Use of this item is restricted to the UNT Community
Part I. The syntheses of a series of stable ferrocenylsilane compounds and their corresponding polyradical cations are reported. Electron spin properties of these molecules were investigated by cyclic voltammetry, ESR, and magnetic susceptibility measurements. All the compounds presented, showed significant electronic communication (>100 mV) between the redox centers by CV. Part II. Baeyer-Villiger oxidation of (1,9-dimethyl-PCU-8,11-dione) was performed using m-chloroperoxybenzoic acid in 1:2 molar ratios. The product obtained was the corresponding dilactone 113. The structure of the reaction products was established unequivocally via single crystal X-ray diffraction methods. The reaction of the 1,9-dimethyl-PCU-8,11-dione with 1:1 molar ratio of m-chloroperoxybenzoic acid produced again the dilactone 113, and not the expected monolactone 114. Ceric ammonium nitrate (CAN) promoted oxidation reaction of 1,9-dimethyl-PCU-8,11-dione afforded a mixture of dimethylated lactones, which indicated unique reaction mechanism pathways. These individual isomers, 115 and 116, have been isolated from these mixtures via column chromatography by using silica gel as adsorbent followed by fractional recrystallization of individual chromatography fractions. Structures of these pure products have been established unequivocally by application of single crystal X-ray crystallographic methods.

Ethics in Technical Communication: Historical Context for the Human Radiation Experiments

Access: Use of this item is restricted to the UNT Community
To illustrate the intersection of ethical language and ethical frameworks within technical communication, this dissertation analyzes the history and documentation of the human radiation experiments of the 1940s through the 1970s. Research propositions included clarifying the link between medical documentation and technical communication by reviewing the literature that links the two disciplines from the ancient period to the present; establishing an appropriate historiography for the human radiation experiments by providing a context of the military, political, medical, and rhetorical milieu of the 1940s to the 1970s; closely examining and analyzing actual human radiation experiment documentation, including proposals, letters, memos, and consent forms, looking for established rhetorical constructions that indicate a document adheres to or diverts from specific ethical frameworks; and suggesting the importance of the human radiation documents for studying ethics in technical communication. Close rhetorical analysis of the documents included with this project reveals consistent patterns of metadiscourse, passive and nominal writing styles, and other rhetorical constructions, including negative language, redundancies, hedges, and intensifiers, that could lead a reader to misunderstand the writer's original ethical purpose. Ultimately this project finds that technical communicators cannot classify language itself as ethical or unethical; the language is simply the framework with which …

The Developmental Physiology of the Zebrafish: Influence of Environment and Cardiovascular Attributes

Access: Use of this item is restricted to the UNT Community
Temperature effects on the development of the zebrafish embryos and larvae and adults were examined. It was found that the earlier in development a temperature change was performed on an embryo, the more significant the change in survival and/or subsequent development. Thus, viable temperature ranges for zebrafish widened significantly as development proceeded. Adults reared and bred at 25oC produced embryos that were significantly more successful at the lower range of rearing temperatures compared to embryos produced from adults reared at 28oC. The majority of this study focused on the physiological effects of swim training during development in the zebrafish. The earlier in development the zebrafish larvae were trained, the greater the mortality. Trained free swimming larvae had a significantly higher routine oxygen consumption after 11 days of training, and a higher mass specific routine metabolic rate after 8 and 11 days of training. Trained free swimming larvae consumed significantly less oxygen during swimming and were more efficient at locomotion, compared to control larvae. Training enhanced survival during exposure to extreme hypoxia in all age groups. Performance aspects of training were investigated in attempt to quantify training effects and in most cases, trained fish performed significantly better than controls. As blood …

Access: Use of this item is restricted to the UNT Community
Non-profits are increasing in size and scope to meet social needs that are unmet by the government. Declining financial support, government regulations, and increasing competition force non-profits to become more professional and efficient. Non-profits increasingly engage in commercial activities, joint ventures with for-profits, and employ business techniques such as business planning and marketing. An extensive body of research examines issues related to non-profit performance that supplies a framework for business planning. Business planning may help non-profits to sustain competitive advantages and long-term financial stability. This paper examines the challenges of writing a business plan for non-profits concluding with a sample business plan that takes into consideration advantages, risks, and limitations of non-profits.

Organizational development: A comparison of individual and organizational level change.

Access: Use of this item is restricted to the UNT Community
Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.

The Effect of Increased Collaboration Among the Library Media Specialist and School Personnel on Perceptions of the Roles and Responsibilities of the Library Media Specialist

Access: Use of this item is restricted to the UNT Community
This study measured and explored changes in perceptions of the roles and responsibilities of the library media specialist when the level of collaboration increased. Seven library media specialists targeted four members of their educational communities with whom to increase collaborative activities. Before and after the collaboration began, the library media specialists, the teachers with whom they chose to collaborate, other members from the same educational community, and a control group that did not participate in increased collaboration were given a roles and responsibilities rank-order form. This form was used to measure changes in perceptions regarding the importance of the three roles and selected responsibilities related to the three roles before and after the collaborative experience. The library media specialists and the targeted teachers also kept reflection logs to record factors that enhanced collaboration, factors that inhibited collaboration, and any changes in their teaching style as a result of the collaborative experience. Results indicate that the participating library media specialists themselves experienced the most change. Role identification remains a problem as library media specialists seek to become teaching partners with classroom teachers yet still must keep the library media center aligned with school and district goals and move toward making it …

Weapons of Mass Deception: Opacity and the Israeli Nuclear Program

Access: Use of this item is restricted to the UNT Community
Access to nuclear technology and growing concern over the spread of nuclear weapons triggered an international debate in the 1960s that led to the creation of the Nonproliferation Treaty. Ratified in 1970, NPT was designed to prevent the horizontal spread of nuclear weapons and limit destructive uses of nuclear energy. At the same time, it also normalized the arsenals of existing nuclear states and encouraged exchanges of nuclear information, technology, and materials for peaceful purposes. Nonproliferation policy relies on a theory of the development process that identifies a nuclear frontier to locate evidence of nuclear capabilities. Absent from the proliferation model, however, are cases of covert nuclear weapons programs. For almost 50 years, it has been generally accepted that Israel is a nuclear weapon state, yet Israeli officials have never confirmed nor denied the possession of nuclear weapons. Israel has not signed NPT and has not appeared to conduct a nuclear test, in effect absolving the nuclear program's main reactor from international inspections. Uncertainty surrounding the Israeli program stems from a tradition of deliberate secrecy and deception that constitutes a national policy of opacity. This study argues that opacity has armed Israel with the privilege of nuclear immunity, exempting its …

Hyperspectral and Multispectral Image Analysis for Vegetation Study in the Greenbelt Corridor near Denton, Texas

Access: Use of this item is restricted to the UNT Community
In this research, hyperspectral and multispectral images were utilized for vegetation studies in the greenbelt corridor near Denton. EO-1 Hyperion was the hyperspectral image and Landsat Thematic Mapper (TM) was the multispectral image used for this research. In the first part of the research, both the images were classified for land cover mapping (after necessary atmospheric correction and geometric registration) using supervised classification method with maximum likelihood algorithm and accuracy of the classification was also assessed for comparison. Hyperspectral image was preprocessed for classification through principal component analysis (PCA), segmented principal component analysis and minimum noise fraction (MNF) transform. Three different images were achieved after these pre-processing of the hyperspectral image. Therefore, a total of four images were classified and assessed the accuracy. In the second part, a more precise and improved land cover study was done on hyperspectral image using linear spectral unmixing method. Finally, several vegetation constituents like chlorophyll a, chlorophyll b, caroteoids were distinguished from the hyperspectral image using feature-oriented principal component analysis (FOPCA) method and which component dominates which type of land cover particularly vegetation were correlated.

his study compared auditory behavioral and physiological measures among three subject groups: 1) Normal control subjects, 2) subjects who were on a prescribed SSRI for depression, and 3) subjects who were prescribed an SSRI for depression, but were not medicated at the time of testing. Test measures included: Standard audiological tests (audiometry and tympanometry), electrophysiological procedures for analysis of auditory- evoked brainstem and late responses, and standardized behavioral speech tests (SCAN-A, SSI, and the low predictability sentence list of the R-SPIN). Analysis of results indicated a statistically significant increase of group mean amplitude of the ABR peak V, from 15dBnSL to 55dBnSL, in the non-medicated group compared to controls. Also, the non-medicated group scored significantly less favorably than controls on the most challenging listening condition (-20 MCR) of the SSI, in the left ear. Although other test measures indicated consistent differences between these two groups, they were not, however, significant.

Images of women shopping in the art of Kenneth Hayes Miller and Reginald Marsh, ca 1920-1930.

Access: Use of this item is restricted to the UNT Community
This thesis examines images of women shopping in the art of Kenneth Hayes Miller and Reginald Marsh during the 1920s and 1930s. New York City's Fourteenth Street served Kenneth Hayes Miller and Reginald Marsh, respectively, as a location generating the inspiration to study and visually represent its contemporaneity. Of particular interest to this thesis are relationships between developments in shopping and the images of women shopping in and around Fourteenth Street that populate the paintings of Miller and Marsh. Although, as Ellen Todd Wiley has shown, the emerging notion of the New Woman helped to shape female identity at this time, what remains unstudied are dimensions that geographically specific, historical developments in shopping contributed to the construction of female identity which, this thesis argues, Marsh and Miller related to, by locating in, the department store and bargain store.

Distance Education in the Preparation of Special Education Personnel: An Examination of Videoconferencing and Web-based Instruction

Access: Use of this item is restricted to the UNT Community
This study examined the effectiveness of employing videoconferencing and Web-based instruction in the preparation of special education personnel. Due to the acute shortage of special education personnel, it was anticipated that the use of videoconferencing and online instruction would provide a convenient way for students to attend class without having to travel to the actual location of the educational site. Further, it was believed that this initiative would result in higher student enrollment in special education teacher certification programs, consequently leading to an increase of personnel in the field. Moreover, the increase in personnel would enhance the ability of educational institutions to address the dismal academic, social, and behavioral outcomes of students with disabilities. Information for the study was collected from surveys that investigated how students perceived the use of videoconferencing and web-based instruction in the preparation of special education personnel. Ninety-four graduate students responded to the videoconferencing surveys while 88 responded to the Web-based instruction surveys. Six respondents were randomly selected to participate in face-to-face interviews designed to investigate the effectiveness of both approaches. Findings indicated that videoconferencing and Web-based instruction are convenient ways for students to attend class although videoconferencing sites may not be conveniently located to all …
