Levels of Psychological Health Related to the Cattell Sixteen Personality Factor Test
The purpose of the present study is to develop an operationally defined standard of psychological health which will be proposed as: 1) one of the goals of psychotherapy; 2) a device for aiding in the evaluation of psychotherapy, and 3) a tool for screening those individuals in the general population who are in need of counseling in order to maintain their mental health. digital.library.unt.edu/ark:/67531/metadc130504/
Levels of Questioning Used by Student Teachers and its Effect on Pupil Achievement and Critical Thinking Ability
The purposes of this study were: 1. To determine the effect of levels of questioning used on secondary public school students in social studies, as measured by (a) their achievement scores, and (b) their critical thinking ability; 2. To determine the effect of feedback to student teachers on their patterns of asking convergent and divergent questions, as measured by coding frequencies of each type on an Observation Schedule and Record form? 3. To draw conclusions from the findings--and develop implications concerning levels of questioning used by teachers and the use of feedback from college supervisors to student teachers. digital.library.unt.edu/ark:/67531/metadc164567/
Levels of resourcefulness and motivation as they relate to sales force success: An examination of correlates using the hope theory.
This study sought to determine whether a relationship existed between individual salesperson's levels of goal-directed cognition and motivation and their professional success as determined by the percentage of sales goals achieved. Salespersons represented two companies with national sales forces: one from the financial services industry and one from the apparel manufacturing industry. Both groups of salespeople were responsible for complex selling tasks. The skill sets for these professionals included high levels of communication skills, extensive product knowledge, and competitive market knowledge. Survey research, both paper and pencil and online, was conducted using the Hope Scale developed by C. R. Snyder and associates (1991). Hope is defined as a two-dimensional construct of goal-directed thinking: resourcefulness, thoughtful planning to overcome obstacles to goals, and motivation, cognition to sustain momentum toward goal achievement. Theoretically, upon assessing salespersons' Hope scores, organizations would be better prepared to assist those with low Hope Scale Scores (HSS) in one of the two areas. Those with low resourcefulness scores could be trained in cognitive techniques to overcome obstacles to goal achievement. Those with low motivational scores would be identified for further analysis, from a developmental perspective, to better determine what personally initiates and sustains motivation to attain their goals (Snyder, 1991). This study affirmed two of three parts of the hope theory with regard to salespeople. High Hope scores showed significant correlations with high goal achievement, as did one of the subset scores, motivation. The resourcefulness subset score did not correlate significantly with high goal achievement, and also produced low reliability scores. digital.library.unt.edu/ark:/67531/metadc3323/
The Lexicographer's Daughter: A Memoir
Access: Use of this item is restricted to the UNT Community.
This creative nonfiction dissertation is a memoir of the author's search for the somewhat mysterious hidden past of her father, the lexicographer Charles J. Lovell, who died in 1960, when the author was nine. Her father's early death left the author with many unanswered questions about his past and his family and so she undertakes a search to answer, if possible, some of those questions. Her search takes her to Portland, Maine; New Bedford, Massachusetts; and Pasadena, California, where she tries to discover the facts and uncover the forces that shaped her father's life. Along the way, she realizes how profoundly his death affected and shaped her own life, contributing to the theme of loss that pervades the memoir. In addition, she begins to realize how much her mother, Dixie Hefley Lovell, whose significance she previously overlooked, shaped her life. Ultimately, she comes to understand and accept that some of her questions are unanswerable. digital.library.unt.edu/ark:/67531/metadc68004/

Osgood to measure the meaning of various concepts. digital.library.unt.edu/ark:/67531/metadc131052/
Libertines Real and Fictional in Rochester, Shadwell, Wycherley, and Boswell
Libertines Real and Fictional in Rochester, Shadwell, Wycherley, and Boswell examines the Restoration and eighteenth-century libertine figure as it appears in John Wilmot, Second Earl of Rochester's Satyr against Mankind, "The Maim'd Debauchee," and "Upon His Drinking a Bowl," Thomas Shadwell's The Libertine, William Wycherley's The Country Wife, and James Boswell's London Journal, 1762-1763. I argue that the limitations and self-contradictions of standard definitions of libertinism and the ways in which libertine protagonists and libertinism in general function as critiques of libertinism. Moreover, libertine protagonists and poetic personae reinterpret libertinism to accommodate their personal agendas and in doing so, satirize the idea of libertinism itself and identify the problematization of "libertinism" as a category of gender and social identity. That is, these libertines misinterpret-often deliberately-Hobbes to justify their opposition and refusal to obey social institutions-e.g., eventually marrying and engaging in a monogamous relationship with one's wife-as well as their endorsement of obedience to nature or sense, which can include embracing a libertine lifestyle in which one engages in sexual encounters with multiple partners, refuses marriage, and questions the existence of God or at least distrusts any sort of organized religion. Since any attempts to define the word "libertinism"-or at least any attempts to provide a standard definition of the word-are tenuous at best, it is equally tenuous to suggest that any libertines conform to conventional or standard libertinism. In fact, the literary and "real life" libertines in this study not only fail to conform to such definitions of libertinism, but also reinterpret libertinism. While all these libertines do possess similar characteristics-namely affluence, insatiable sexual appetites, and a rebellion against institutional authorities (the Church, reason, government, family, and marriage)-they often misinterpret libertinism, reason, and Hobbesian philosophy. Furthermore, they all choose different, unique ways to oppose patriarchal, social authorities. These aberrant ways of rebelling against social institutions and their redefinitions of libertinism, I argue, make them self-satirists and self-conscious critics of libertinism as a concept. digital.library.unt.edu/ark:/67531/metadc6051/
Librarians' Attitudes Toward Computers, Desktop Publishing Systems and Expert Systems
In the discipline of librarianship there is very little existing research from which conclusions regarding attitudes toward computers and related technology can be drawn. Furthermore, there is no significant data available which indicates that attitudes differ between various groups or types of librarians. It is reasonable to assume that librarians' attitudes toward computers vary. This study examines a group of academic librarians and a group of public librarians and tests for significant differences in their respective attitudes toward computers, desktop publishing systems and expert systems. digital.library.unt.edu/ark:/67531/metadc277903/
Licensed Professional Counselors’ Attitudes Toward People with Schizophrenia: Predictors of Interest in Providing Interventions
For individuals with schizophrenia and their caregivers, psychosocial interventions have been shown to significantly improve recovery and reduce relapse rates. Although this population is underserved and stigmatized, counselors have been excluded from most research into attitudes toward and interventions for these families. Using a stratified random sample survey design, researchers explored the relationships between participating U.S. Licensed Professional Counselors’ attitudes towards, recovery beliefs regarding, familiarity with, desire for social distance from, and interest in providing services to individuals with schizophrenia and their caregivers. Most of the 111 participants (11.1% response rate) identified themselves as female (83.8%) and Caucasian (86.5%). A few participants described themselves as Hispanic (6.3%) or Black or African-American (5.4%). Respondents ranged in age in years from 20’s to 60’s with the largest group in their 40’s. Descriptive statistics indicated that the majority of LPC participants reported low to moderate stigmatizing attitudes, strong beliefs in recovery, and moderate to high interest in providing interventions for people with schizophrenia and their caregivers. Furthermore, almost half of participating LPCs reported already working with individuals with schizophrenia. Bivariate correlations and hierarchical regressions indicated that high interest in providing interventions for this population was significantly correlated (p < .01) with high frequency of already working with the population (large effect), low desire for social distance (medium effect), high desire to help socially (medium effect), and strong beliefs in recovery (small effect). The results support including LPCs in all areas pertaining to interventions, research, and recovery for people with schizophrenia and their caregivers. digital.library.unt.edu/ark:/67531/metadc149610/

Life history and case building behaviors of Phylloicus ornatus (Banks)(Trichoptera: Calamoceratidae) In two spring fed tributaries in the central Edwards Plateau bioregion of Texas
Access: Use of this item is restricted to the UNT Community.
The life history and case-making behaviors of Phylloicus ornatus from two springfed first order streams in the Edwards Plateau Bioregion of Texas were studied from January 1998 to November 1999. Field larval, pupal and adult samples and laboratory rearings indicated a multivoltine cycle. First instars differ from late instars in number of labral setae and in having a unique spur-like claw on each lateral hump. Larval development was asynchronous with second through fifth instars and pupae present most months. First instars were present April through July, October and November. Case making of first instar and case reconstruction of later instars extracted from their cases was documented by videophotography. digital.library.unt.edu/ark:/67531/metadc2555/
The Life History and Contributions to the Ecology of Camelobaetidius variabilis Wiersema 1998 (Ephemeroptera: Baetidae) in Honey Creek, Oklahoma
A study of the life history and ecology of Camelobaetidius variabilis was conducted in Honey Creek, OK from February 2003-April 2004. Nymph development was assessed using changes in external morphology. Laboratory reared nymphs were used to calculate number of degree days to complete development (772 degree days at 20.8° C ±.38° C), which was used to determine voltinism. Field collected nymph microhabitat distribution was used in assessing microhabitat distribution. Nymphal thermoregulation was assessed during the winter and spring by comparing nymphal numbers present in shaded and un-shaded habitats. Camelobaetidius variabilis nymphs showed preference for algal microhabitats during the spring and leaf packs in the winter. Nymphs inhabited leaf packs to increase metabolic rate during the winter. Increased temperatures aid in development of nymphs. Camelobaetidius variabilis exhibited a multivoltine life cycle with six overlapping generations. digital.library.unt.edu/ark:/67531/metadc4944/

Life History and Secondary Production of Caenis latipennis Banks (Ephemeroptera: Caenidae) in Honey Creek, Oklahoma
A study of the life history and secondary production of Caenis latipennis, a caenid mayfly, was conducted on Honey Creek, OK. from August 1999 through September 2000. The first instar nymph was described. Nymphs were separated into five development classes. Laboratory egg and nymph development rates, emergence, fecundity, voltinism, and secondary production were analyzed. C. latipennis eggs and nymphs take 132 and 1709 degree days to develop. C. latipennis had an extended emergence with five peaks. Females emerged, molted, mated, and oviposited in an estimated 37 minutes. Mean fecundity was 888.4 ± 291.9 eggs per individual (range 239 -1576). C. latipennis exhibited a multivoltine life cycle with four overlapping generations. Secondary production was 6,052.57 mg/m2/yr. digital.library.unt.edu/ark:/67531/metadc2863/
Life History And Secondary Production Of Cheumatopsyche Lasia Ross (Trichoptera: Hydropsychidae) With Respect To A Wastewater Treatment Facility In A North Texas Urban Stream
This study represents the first shift in multivoltine life history of Cheumatopsyche species from a wastewater treatment plant (WWTP) in North America. Populations of C. lasia were examined upstream and downstream of the Denton’s Pecan Creek WWTP August 2009 through November 2010. C. lasia is multivoltine in Pecan Creek with three cohorts observed upstream of the WWTP and four possible cohorts downstream. A fourth generation was possible downstream as thermal inputs from WWTP effluent resulted in elevated water temperatures that allowed larval development to progress through the winter producing a cohort ready to emerge in spring. Production of C. lasia was 5 times greater downstream of the WWTP with secondary production estimates of 1.3 g m-2 yr-1 and 4.88- 6.51 g m-2 yr-1, respectively. Differences in abundance were due to increased habitat availability downstream of the WWTP in addition to continuous stream flow from inputs of wastewater effluent. Results also suggest that C. lasia is important for energy transfer in semiarid urban prairie streams and may serve as a potential conduit for the transfer of energy along with emergent contaminants to terrestrial ecosystems. These finding highlight the need for more quantitative accounts of population dynamics (voltinism, development rates, secondary production, and P/B) of aquatic insect species to fully understand the ecology and energy dynamics of urban systems. digital.library.unt.edu/ark:/67531/metadc103372/
Life History of Mayatrichia ponta Ross (Trichoptera: Hydroptilidae) in Honey Creek, Turner Falls Park, Oklahoma
The life history and ontogenetic microhabitat change of Mayatrichia ponta Ross were investigated in Honey Creek, Turner Falls Park, Murray Co., Oklahoma, U.S.A. from August 1994 to August 1995. The shape of larval cases changed from a small cone to a cylinder. M. ponta had an asynchronous multivoltine life history with considerable cohort and generation overlap; five generations were estimated. The development rate was reduced in winter. The winter generations of M. ponta had wider head capsule widths (136-165 μm) than summer generations (121-145 μm). The sex ratio of adults was 1.43 ♂ : 1 ♀. Fecundity ranged from 46 to 150 eggs/female. Fifth instar larvae and pupae aggregated on the bottom side of substrates. Early instars were distributed evenly on all sides of substrates. General patterns of ontogenetic microhabitat shift in aquatic insects are categorized as flow mediated, flow independent, and population interactions and other resources mediated. digital.library.unt.edu/ark:/67531/metadc278261/
Life in the Early Mining Camps of Colorado
The story of the advancing American frontier has unending interest. Perhaps one of the most colorful and unusual frontier developments was that of the mining frontier in the Rocky Mountains of Colorado. During the years following the discovery of gold in 1858 and the early 1880's occurred an almost unprecedented evolution from a primitive pioneer society to complex industrial development. digital.library.unt.edu/ark:/67531/metadc130398/
Life of the Enlisted Soldier on the Western Frontier, 1815-1845
In contrast to the relatively rapid changes occurring in the modern American army, the period between the end of the War of 1812 and the beginning of the Mexican War offers a definite period for a study of military life when reform came slowly. During the period of study, leaders made few attempts to reform the general structure of the military institution as a social system. On the other hand, many changes can be discerned which improved weaponry and equipment, tactics, supply and administrative procedures, moral guidance, recreational facilities, and pay. digital.library.unt.edu/ark:/67531/metadc278351/
Life without Parole for Juvenile Offenders: Questions of Legality and Adolescent Culpability
Life without parole for juvenile offenders is a controversial issue across the globe. Recently, the United States stands alone as the only country in the world that allows juvenile offenders to be sentenced to life time confinement without the possibility of parole. Furthermore, the U.S. has seen an increase in juvenile waivers and blended sentences, which has resulted in harsher penalties for juvenile offenders who have committed serious and violent crimes. This analysis examines scientific evidence that shows juveniles are different from adults in terms of brain development, rational decision making abilities, and maturity levels. These findings have questioned the reasoning behind imposing adult punishment on adolescent behavior. This analysis also presents the legal arguments suggesting that juvenile life without parole is unconstitutional and violates the Eighth and Fourteenth Amendments. Arguments for and against life sentences were also presented. This study concludes with a discussion of policy implications, whether the U.S. Supreme Court should abolish juvenile life without parole sentencing practices and explores the possible future direction of juvenile sentencing in the United States. digital.library.unt.edu/ark:/67531/metadc31530/

Light, Bright, and Out of Sight: Hollywood’s Representation of the Tragic Mulatto
The purpose of this research is to examine the longevity of the stereotype of the tragic mulatto in American film history. Specifically, my research focuses on the portrayals and perceptions of biracial actresses. Media informs, entertains, and influences how we, and especially youth, self-identify and interact with others. This research focuses on the portrayal of biracial actresses throughout film history. It is also important in its investigation of the perpetuation of the one-drop rule. In this research, I will examine if historical stereotypes of tragic mulatto are apparent in contemporary Hollywood film. The methodologies used in this research include a content analysis of films with biracial actresses and an online survey of respondents’ perceptions of four actresses. Statistical techniques used for analysis include ordinary least square regression and multinomial logistic regression. Findings suggest that the tragic mulatto stereotype is not blatant in contemporary Hollywood film, but issues of colorism may be apparent. digital.library.unt.edu/ark:/67531/metadc407836/
The Light, for Two Narrators and Chamber Ensemble
The Light is a twenty-four minute composition for two narrators and chamber orchestra. The two narrators perform the roles of the Apostle John and Moses. After an overview of the piece and a brief history of pieces incorporating narrators, the essay focuses on my compositional process, describing how orchestration, drama, motive, and structure work together in the piece. The Light is organized as a series of five related scenes. In the first scene, God creates light. In the second scene, God places Adam and Eve into the Garden of Eden to tend it, allowing them to eat from any tree except the tree of the knowledge of good and evil. The serpent appears, Adam and Eve succumb to his evil influence, and God banishes them from the Garden of Eden. Many generations have passed when Scene Three begins. Moses relates a story from Israel's journey in the wilderness after leaving Egypt. The people had become frustrated with Moses and with God. When God sent serpents among them as punishment, they appealed to Moses to pray for them. God's answer was for Moses to make a bronze serpent and place it on a pole. Whoever looked at the serpent would live. In Scene Four, John relates his vision of final redemption. New Jerusalem descends from heaven, with the River of Life and the Tree of Life ready to bring healing to the nations. Sadly, some people are not welcomed into the city, and the drama pauses to give respectful consideration to their fate. Finally, the fifth scene celebrates the eternal victory over sin, death, and the serpent of Eden. As I composed The Light, I had in mind the dramatic profile, the general motivic progression and the fundamental structural progression. However, most of the intricate interrelationships among orchestration, drama, motive, and structure were the result of informed intuition. Throughout the piece, each of these four elements interacts with the others, sometimes influencing and sometimes responding to them. My hope is that these subtle tensions propel the composition forward toward its ultimate resolution. digital.library.unt.edu/ark:/67531/metadc4220/

Light Spectra Distributions in Temperate Conifer-Forest Canopy Gaps, Oregon and in Tropical Cloud-Forest Canopy, Venezuela
Light spectra distributions were measured in two different montane forests: temperate and tropical. Spectral light measurements were made in different sized canopy gaps in the conifer forest at H. J. Andrews Experimental Forest in Oregon, USA. Researchers at Oregon State University created these gaps of 20 m, 30 m, and 50 m in diameter. In the tropical cloud forest, spectral light measurements were made in two plots that were permanently established at La Mucuy Parque Nacional in Venezuela, in collaboration with researchers at Universidad de Los Andes. In both studies, spectra and distributions of physiologically active light were analyzed: red, far-red, R/FR ratio, and blue light. digital.library.unt.edu/ark:/67531/metadc279052/

Limiting Disability Post-Brain Injury Through a Physical Activity Centered Education Program
Brain injury (i.e., traumatic brain injury, stroke) is a considerable public health issue due to complicated outcomes of the injury, increasing incidence, and high costs linked with medical treatment. Rehabilitation centers are challenged to help individuals manage the resultant associated conditions and prevent secondary and chronic conditions. Research has shown that health promotion programs (HPP) that incorporate education about physical activity (PA) are one mode of rehabilitation that can improve the health of individuals with disabilities. However, PA is not included in the rehabilitation program for individuals with a brain injury, indicating a gap in the services provided. Consequently, the purpose of this study was to create and implement a physical activity centered education (PACE) program within an outpatient rehabilitation program. PACE consisted of an 8-week (16 session) program which aimed to (1) increase PA self-efficacy, (2) increase intention to change PA behaviors, (3) increase amount of PA completed regularly, and (4) promote positive rehabilitation outcomes. Based on previous research it was hypothesized that participation in PACE would result in (1) increased PA self-efficacy, (2) forward progression in intention to change PA behaviors, (3) increased amount of PA completed, and (4) improved rehabilitation outcomes (i.e., abilities, adjustment, participation). The PACE program resulted in an average increase of 16.1% in participants’ PA self-efficacy (effect size [ES] = 0.41), an increase from three of nine participants at pre-test to six of nine participants at post-test reporting to be in a stage of change in which they are most likely to be successful in regular PA participation (i.e., action or maintenance), and a comparable improvement in MPAI-4 scores (rehabilitation outcomes) after discharge to a rehabilitation program without a PA education component. In conclusion, the PACE program can improve PA self-efficacy, intention to change PA behaviors, and short-term rehabilitation outcomes. digital.library.unt.edu/ark:/67531/metadc84224/

Lind, James Meyer the Trumpet Concertos of Anthony Plog: a Performer’s Guide
Anthony Plog (b. 1947) has contributed several notable works for brass instruments. He is known for writing extremely technically challenging works that contain angular melodies, fast rhythms and a large degree of chromaticism. Though his music is difficult, it also conveys intense emotions. His music for trumpet, specifically Concerto no. 1 for Trumpet, Brass Ensemble and Percussion and Concerto no. 2 for Trumpet and Orchestra, represents a zenith in his compositional development. This dissertation examines Concerto no. 1 and Concerto no. 2 from a performer’s perspective to better understand the stylistic characteristics and challenges encountered in his music. Each concerto is examined in terms of rhythmic structure, intervallic structure, thematic material, motivic material and form. digital.library.unt.edu/ark:/67531/metadc149631/

Linear, Nonlinear Optical and Transport Properties of Quantum Wells Composed of Short Period Strained InAs/GaAs Superlattices
In this work, ordered all-binary short-period strained InAs/GaAs superlattice quantum wells were studied as an alternative to strained ternary alloy InGaAs/GaAs quantum wells. InGaAs quantum wells QWs have been of great interest in recent years due to the great potential applications of these materials in future generations of electronic and optoelectronic devices. The all binary structures are expected to have all the advantages of their ternary counterparts, plus several additional benefits related to growth, to the elimination of alloy disorder scattering and to the presence of a higher average indium content. digital.library.unt.edu/ark:/67531/metadc278855/

Linearity and monotonicity of a 10-bit, 125 MHz, segmented current steering digital to analog converter
The purpose of this research is to determine the linearity and monotonicity of the THS5651IDW digital to analog converter (DAC), a prototype of the future Texas Instruments TLV5651, 10-bit, 125 MHz communication DAC. Testing was conducted at the Texas Instruments facility on Forest Lane, Dallas, Texas. Texas Instruments provided test equipment, software and laboratory space to obtain test data. Analysis of the data found the DAC to be monotonic since the magnitude of the differential nonlinearity (DNL) was less than ± 1 least significant bit (LSB) and the integral nonlinearity (INL) was less than ± 0.5 LSB. The study also showed that the DAC has primarily negative DNL although the DNL is well within the desired specification. digital.library.unt.edu/ark:/67531/metadc2541/

Pseudomonas fluorescens NCIMB 11764 (Pf11764) is uniquely able to grow on the poison cyanide as its sole nitrogen source. It does so by converting cyanide oxidatively to carbon dioxide and ammonia, the latter being assimilated into cellular molecules. This requires a complex enzymatic machinery that includes nitrilase and oxygenase enzymes the nature of which are not well understood. In the course of a proteomics analysis aimed at achieving a better understanding of the proteins that may be required for cyanide degradation by Pf11764, an unknown protein of 17.8 kDa was detected in cells exposed to cyanide. Analysis of this protein by ESI-coupled mass spectrometry and bioinformatics searches gave evidence of strong homology with a protein (Hyp1) of unknown function (hypothetical) present in the bacterium Photorhabdus luminescens subsp. laumondii TTO1 (locus plu_1232). A search of available microbial genomes revealed a number of Hyp1 orthologs the genes of which are found in a conserved gene cluster known as Nit1C. Independent studies revealed that in addition to Hyp1, Pf11764 possesses a gene (nit) specifying a nitrilase enzyme whose closest homologue is a nitrilase found in Nit1C gene clusters (77% amino acid identity). DNA sequence analysis has further revealed that indeed, hyp1Pf11764 and nitPf11764 are contained in a cluster that includes also a gene specifying an oxygenase. Given the possible connection of Nit1C-endoded nitrilase and oxygenase enzymes to enzymatic cyanide degradation, there is strong reason for thinking that the genes specifying these enzymes contribute to bacterial growth on cyanide in those bacteria containing the Nit1C cluster. Because the biological function of the Hyp1 protein is currently unknown, it was cloned and the protein expressed in E. coli so that its properties could further be explored. Unfortunately, the expression of the protein in an insoluble form complicated these analyses. However, at least two lines of evidence suggest a possible role as a regulator of gene expression. First, over-expression of the protein was accompanied by the parallel elevation of the putative vector-encoded b-lactamase, implying that Hyp1Pf11764 can affect the expression of other genes. Second, a comparison of the amino acid sequence of select peptide fragments of Hyp1Pf11764, by conducting searches for homology with proteins in the existing nonredundant protein database, consistently revealed motifs in common with those present in bacterial response regulators that are part of two-component signal transduction systems widely distributed in bacteria. digital.library.unt.edu/ark:/67531/metadc10993/
Linkage of Business and Manufacturing Strategies as a Determinant of Enterprise Performance: an Empirical Study in the Textile Industry
The main question in this study was: do business units that exhibit a "linkage" or "fit" between their business strategy and manufacturing strategy variables, outperform competitors who lack such a fit? This exploratory research focused on two business strategies: cost leadership and differentiation. Based on existing literature, twenty-four hypotheses concerning the relationship between business strategy and selected manufacturing strategy variables were developed. The manufacturing executives of eighty-eight broadwoven cotton fabric mills (SIC 2211) were surveyed using a qualitative questionnaire. Two sets of comparisons were made between the manufacturing strategy variables of the sampled firms: first, high vs. low performers pursuing cost leadership strategy; and second, high vs. low performers focusing on differentiation strategy. Within each set of comparisons, high performers reported linkage between their business strategies and selected manufacturing strategy variables. This study re-affirms the importance of linking business strategy with manufacturing strategy variables as a forceful weapon for overcoming competition. digital.library.unt.edu/ark:/67531/metadc278687/
Linkages between the Texas Supreme Court and Public Opinion
This investigation sought to identify linkages between the Texas Supreme Court and public opinion through 1) a matching of written decisions with scientifically conducted public opinion polls; 2) direct mention of public opinion and its synonyms in Texas justices' decisions; 3) comparison of these mentions over time; and 4) comparison of 10 personal attributes of justices with matched decisions. The study moved the unit of analysis from the U.S. Supreme Court to the state court level by using classification schemes and attribute models previously applied to the U.S. Supreme Court. It determined that linkages exist between the Texas Supreme Court's written decisions and public opinion from 1978 to July 1994. digital.library.unt.edu/ark:/67531/metadc278024/
Links among perceived service quality, patient satisfaction and behavioral intentions in the urgent care industry: Empirical evidence from college students.
Patient perceptions of health care quality are critical to a health care service provider's long-term success because of the significant influence perceptions have on customer satisfaction and consequently organization financial performance. Patient satisfaction affects not only the outcome of the health care process such as patient compliance with physician advice and treatment, but also patient retention and favorable word-of-mouth. Accordingly, it is a critical strategy for health care organizations to provide quality service and address patient satisfaction. The urgent care (UC) industry is an integral part of the health care system in the United States that has been experiencing a rapid growth. UC provides a wide range of medical services for a large group of patients and now serves an increasing population. UC is becoming popular because of the convenient locations, extended hours, walk-in policy, short waiting times, and accessibility. A closer examination of the current health care research, however, indicates that there is a paucity of research on urgent care providers. Confronted with the emergence of the urgent care industry and the increasing demand for urgent care, it is necessary to understand how patients perceive urgent care providers and what influences patient satisfaction and retention. This dissertation addresses four areas relevant to the above mentioned issues: (1) development of an instrument to measure perceived service quality in the urgent care industry; (2) identification of the determinants of patient satisfaction and behavioral intentions; (3) empirical examination of the relationships among perceived service quality, patient satisfaction and behavioral intentions; and (4) comparison of the perceived service quality across several primary urgent care providers, such as urgent care centers, hospital emergency departments, and primary care physicians' offices. To validate this new instrument and examine the hypothesized relationships proposed in this study, an electronic web based survey was designed and administered to college students. Both exploratory and confirmatory factor analysis were employed to assess the reliability and validity of the developed instrument. The contextualized relationships were evaluated using structural equation modeling. The results of this research could potentially contribute to urgent care management and quality improvement. digital.library.unt.edu/ark:/67531/metadc11014/
Lipids and Phospholipase Activity of Vibrio Cholerae
One purpose of this investigation is to determine the fatty acid and lipid content of typical Vibrio cholerae cells. The comparison of cholera lipid constituents with those of closely-related bacteria might be of taxonomic value. Furthermore, chemical characterization of the cholera vibrio could provide useful criteria for identification of these disease-producing microorganisms. digital.library.unt.edu/ark:/67531/metadc279194/
Lipodystrophy, Body Image and Depression in Hiv Positive Black Women
Human immunodeficiency virus (HIV) seropositive men on highly active antiretroviral therapy treatment (HAART) who experience lipodystrophy syndrome (LD), a side effect of HAART, rate themselves as more depressed than those who did not experience LD(Crane et al., 2008). Furthermore, men who rated their LD symptoms as more severe also scored higher on depression measures than men who experienced less severe symptoms. It is unknown these findings can be generalized to other groups of HIV positive individuals. The current study seeks to fill this gap in the literature by exploring the associations between LD, body image, and depressive symptoms in an archival sample of HIV positive Black women. This study aims to describe the body changes associated with HAART in a Black female sample and explore the relationships between LD, body image, depression, and quality of life. Findings supported past research indicating a correlation between depression and poor body image but did not indicate that body image quality of life moderated the relationship between perceived body changes and depression. Results expanded on the literature by indicating that perceived body changes may be more distressing to Black women with HIV than objective changes. Lastly, findings suggested that Black women may have inaccurate perceptions of their own body changes. These findings are particularly informative for healthcare workers who treat HIV+ women. It is imperative that they consider clients’ self-report as well as clinical symptoms. digital.library.unt.edu/ark:/67531/metadc500152/
