Emergency Physician Communication Style and Career Satisfaction: Is There a Correlation?
The correlation between social style and career satisfaction among emergency physicians was investigated. An e-mail survey was sent to a random sample of 1,000 members of the American College of Emergency Physicians in practice for at least three years; 707 had valid e-mail addresses. A twenty-item behavioral style survey instrument and a five-item career satisfaction scale were used. The study incorporated prenotification and reminder e-mails. Valid responses were obtained from 329 physicians (46.5%). No correlation was shown between social style and career satisfaction. Problems with both survey instruments were discovered. Survey respondents were unhappy with their careers, with an average satisfaction of 4.03, 1 being very satisfied, 5 very dissatisfied. Areas for future study include redoing the study using different survey instruments. digital.library.unt.edu/ark:/67531/metadc3330/
Ensuring Authenticity and Integrity of Critical Information Using XML Digital Signatures
Access: Use of this item is restricted to the UNT Community.
It has been noticed in the past five years that the Internet use has been troubled by the lack of sufficient security and a legal framework to enable electronic commerce to flourish. Despite these shortcomings, governments, businesses and individuals are using the Internet more often as an inexpensive and ubiquitous means to disseminate and obtain information, goods and services. The Internet is insecure -- potentially millions of people have access, and "hackers" can intercept anything traveling over the wire. There is no way to make it a secure environment; it is, after all, a public network, hence the availability and affordability. In order for it to serve our purposes as a vehicle for legally binding transactions, efforts must be directed at securing the message itself, as opposed to the transport mechanism. Digital signatures have been evolved in the recent years as the best tool for ensuring the authenticity and integrity of critical information in the so called "paperless office". A model using XML digital signatures is developed and the level of security provided by this model in the real world scenario is outlined. digital.library.unt.edu/ark:/67531/metadc3282/
Eplucher Les Oignons (Peeling the Onions)
My creative intent is to connect with viewers at an emotional level. My chosen metaphor is “Peeling the Onion.” The implication of the metaphor is that understanding is achieved after one looks below the surface and views the underlying “layers.” The challenge is to find images that are personally interesting and also connect with the viewer. At times the creative process proceeds in linear manner and at other times it seems to take on a life of its own. During my search for a balance between the literal and ambiguous, I explored the circle, the spiral and the sphere. Printmaking offers unique opportunities to produce evocative imagery. Drawing is the basic tool I employ to define form and my use of printmaking processes allows for evolving the image over time. The immediacy and spontaneity of my drawings is combined with a methodical approach to image development. Exploring the spiral, sphere, circles and the metaphor “Peeling the Onion” has provided me a means of giving a form to my concepts and hopefully a connection with the viewer. digital.library.unt.edu/ark:/67531/metadc3301/
An Evaluation of the Effects of a Pay for Performance Plan on Productivity of Employees of a Professional Services Firm
This study examined the effects of a productivity-indexed pay for performance plan in a professional services firm. The new plan was implemented after productivity decreased under an existing plan. Performance of staff and senior level accountants was analyzed across three departments under a three-year baseline and a two-year intervention period. Several measures of productivity indicated that the intervention was effective in improving production, especially for employees with full annual workloads. Percentage of salaries earned in incentives was comparable for both the baseline and intervention periods. Possible explanations for trends in the data, weaknesses in the plan, and implications for future research are also discussed. digital.library.unt.edu/ark:/67531/metadc3322/
An Examination of American Sideshow Banners as Folk Art, ca. 1920-1960
This thesis redresses the lack of scholarly attention paid to painted circus banners produced in the United States during the first half of the twentieth century by exploring the extent to which American folk art painting scholarship, methodologies, and objects can be used to articulate the meaning and significance of banner painting. This study expands the disciplinary treatment of banner painting by introducing domesticated art as a means of representing non-academic art produced in the U.S. The thesis also presents a model for exploring banner painting after identifying traditional American folk art painting methodologies, which fail to investigate banner painting style, format, and artistic training associated with banner work. digital.library.unt.edu/ark:/67531/metadc3302/
The Exploration of Surface and Texture on the Inside and Outside of My Sculpture
After generating work for many years in an intuitive, “truth to materials” mindset my intent was to explore the interior possibilities of my sculptural forms and relate these if possible, to the exterior. Alongside this exploration of the interior I introduced surface texture and color onto both interior/exterior surfaces. In some cases the work had undergone a change, which lent new meaning and provided new relationships to exist between the interior/exterior of my sculpture. Not all of the work was satisfactory to me, though I feel there were many positive results from work that may not have been successful. I found that the integration of the interior/exterior dialogue into my existing work provided new meaning allowing new relationships within the work that had not existed previously. digital.library.unt.edu/ark:/67531/metadc3339/
Faculty Practice Among Commission of Collegiate Nursing Education Accredited Nursing Schools
This descriptive survey study investigated the value of faculty practice among Commission of Collegiate Nurse Education (CCNE) Accredited Nursing Schools. The sample included all CCNE accredited schools that offered a Masters degree. Subjects from the 66 schools in the sample the dean and three Nurse Practitioner faculty who are teaching a clinical course. Response rate was 51% for the deans and 35% for the faculty. The opinions of deans were compared to the opinions of faculty on the views of faculty practice as research and the incorporation of faculty practice in the tenure and merit review system. The results showed faculty and deans differed on the value of faculty practice as research. However, only 6.5 % of statistically significance difference was contributable to whether the response was from a dean of a faculty. There was no significant difference to the inclusion of faculty practice in the tenure and merit review system. Boyer's expanded definition of research was used as a theoretical background. Deans viewed faculty practice more important as compared to the traditional faculty expectation of research than faculty did. The operational definition of faculty practice was that it required scholarly outcomes from the practice. Deans were more willing than faculty to acknowledge there were scholarly measurable outcomes to evaluate faculty practice than faculty were. The greatest difference in opinion of outcomes was the deans were more willing to accept clinically focused articles as an outcome than faculty were. Faculty were asked how the money from faculty practice was distributed. Faculty overwhelmingly reported that money generated from faculty practice most often goes to the individual faculty member. Suggested areas for future research involve investigation of the role of tenure committees in tenure decisions relating to research and faculty practice. digital.library.unt.edu/ark:/67531/metadc3317/
Gender, Identity, and Influence: Hong Kong Martial Arts Films
This project is an examination of the Hong Kong film industry, focusing on the years leading up to the handover of Hong Kong to communist China. The influence of classical Chinese culture on gender representation in martial arts films is examined in order to formulate an understanding of how these films use gender issues to negotiate a sense of cultural identity in the face of unprecedented political change. In particular, the films of Hong Kong action stars Michelle Yeoh and Brigitte Lin are studied within a feminist and cultural studies framework for indications of identity formation through the highlighting of gender issues. digital.library.unt.edu/ark:/67531/metadc3354/
Germinal Ideas and Processes within plies (2002): A Chamber Work for Eleven Players
The piece is a twenty minute work discoursing the integration and eventual dissolution of two separate musical strands. The pitch material of each strand is determined from synthetic scales whose intervalic content duplicates at the following intervals: Perfect 12th, Diminished 12th, Minor 9th, Perfect 8ve, and Major 7th. A proportional means of temporal compression is generated through the use of the factor, 11/15 (e.g. Event 2 is 11/15 the duration of Event 1). Various elements of jazz music informed the construction of plies, including the instrumentation of the ensemble and the means by which the performers interact throughout the piece. Internal cueing and performer decisions are meant to eliminate the need of a conductor in favor of increased interpretive freedom by the performers. digital.library.unt.edu/ark:/67531/metadc3309/
Greek texts and English translations of the Bible: a comparison and contrast of the Textus Receptus Greek New Testament of the sixteenth century and the Alexandrian text of Westcott and Hort (nineteenth century) and Aland and Metzger (twentieth century) concerning variant texts that pertain to the orthodox Christology of the Council of Nicea, A.D. 325.
The argument of this paper is that certain salient passages in the New Testament concerning Christology, as it was defined in the Nicene creed in A.D. 325, reflect such orthodoxy better in the Textus Receptus Greek texts and the English translations made from them than do the Alexandrian texts. Arian theology, which was condemned as heretical at Nicea, is examined. Patristic quotations, historical texts, and arguments of the scholars are cited and traced, along with a comparison of Christological verses. digital.library.unt.edu/ark:/67531/metadc3315/

Furthermore, this study will also examine Anglo-Tejano interaction and Anglo American intentions toward Texas. It will also outline how Anglo Americans made determine efforts to wrest Texas away from Spain and México. Finally, the thesis examines Tejano cultural perseverance whose indelible imprint still resonates today. digital.library.unt.edu/ark:/67531/metadc3345/
Group activity therapy with learning disabled preadolescents exhibiting behavior problems.
This study was designed to determine the effectiveness of group activity therapy as a school based intervention with fourth and fifth grade preadolescents with learning disabilities experiencing behavior problems. The group activity therapy intervention followed humanistic principles and was designed to address the cognitive and social emotional needs of this population. The preadolescents were provided a variety of developmental appropriate materials and activities to encourage self expression and group interaction. The 24 volunteer preadolescents were randomly assigned to the experimental group (n=12) and to the control group (n=12). The treatment group preadolescents were divided into groups of three and participated in group activity therapy one hour per week for 12 weeks. The participants were assigned to groups according to individual needs and personality traits. The control group received no treatment during the study. Pre and post test data were collected from parents using the Child Behavior Checklist (CBC) and the Behavior Assessment Scale for Children (BASC). Analysis of Covariate (ANCOVA) was utilized to determine statistical significance between the treatment group and the control group on the post-test means for each hypothesis. In each case, the post-test specified in each hypothesis was used as the dependent variable and the pre-test as the covariate. Specifically, the preadolescents in the treatment group showed statistically significant decreases in total behavior problems on the BASC (p=.05) and decreases in internalizing problems on both the BASC and CBC (p=.03, p=.05, respectively). While not statistically significant, positive trends were noted on the CBC total behavior scale (p=.08) and on the CBC externalizing scale (p=.09). In addition, Cohen's d effect size was calculated for each hypothesis and post hoc analysis of the subscales to determine practical significance of the treatment on the experimental group when compared to the control group. A large treatment effect size was found on the BASC (d=.91) and CBC (d=.82) total behavior problems scales and on the BASC (d=1.03) and CBC (d=.90) internalizing problems scales. A moderate to large treatment effect size (d=.78) was found on the CBC externalizing problems scale and a medium treatment effect size (d=.53) was found on the BASC externalizing problems scale. Qualitative data was also examined to determine clinical significance of the intervention. This study determined that group activity therapy is an effective intervention for preadolescents diagnosed with a learning disability. digital.library.unt.edu/ark:/67531/metadc3326/

Imitating Nature
Through my art I seek to communicate the continuing cycle of change that unites all life forms. I had to find methods of presentation and surface that would enhance my sculptural statements that I had begun to address. Utilizing salt, wood and low temperature sagger firing, resulted in softer, more natural appearing surfaces. These surfaces complimented and completed the organic forms with which I was working. The problems encountered in presentation were rectified by alternately contrasting the surfaces of the presentation with the surfaces of the pieces, while utilizing forms that echoed the natural forms of the pieces. The opposite approach also worked well, using natural presentation materials to create a sense of unity, and geometric bases for contrast. These methods resulted in an increased sense of energy, unity and completion in the work presented. digital.library.unt.edu/ark:/67531/metadc3340/
The impact of drug testing on secondary school students.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study determined whether use of student random drug testing provided an effective means to reduce drug usage by secondary school students. The participants included 50,214 7th through 12th grade students in 12 selected public schools. All school districts participated in the Texas School Survey of Substance Use in 1994, 1996, 1998, and 2000. The six districts in the experimental group used drug testing as a method of reducing drug usage among students. The six districts in the control group did not use drug testing. Although athletes and students involved in extracurricular activities remain the focus of random dug testing, this research focused on an entire school population to determine whether drug testing only a select group of students reduced reported drug usage in the entire school. Two questions guided the research: First, does the use of random drug testing have an impact on student drug usage? Second, does the year of implementation of random drug testing have an impact on students' self-reported drug usage? The findings for each research question were categorized according to nine illegal drugs. The researcher used a one-way repeated measures factorial design. The data were analyzed via the univariate (split-plot) 2 x 4 analysis of variance (ANOVA), with the data from four periodic surveys (1994, 1996, 1998, & 2000) as a within-subject factor and the treatment group (participation in drug testing or control/no drug testing) as a between-subjects factor. The results of the study showed there was no statistically significant difference between the experimental group of school districts that used random drug testing and the control group of school districts that did not use random drug testing. In addition, the study showed there was no statistically significant difference in drug usage between the students in districts who began random drug testing in different years (i.e. 1994, 1996, 1998, & 2000). digital.library.unt.edu/ark:/67531/metadc3281/
Implementation of Back Up Host in TCP/IP
Access: Use of this item is restricted to the UNT Community.
This problem in lieu thesis is considering a TCP client H1 making a connection to distant server S and is downloading a file. In the midst of the downloading, if H1 crashes, the TCP connection from H1 to S is lost. In the future, if H1 restarts, the TCP connection from H1 to S will be reestablished and the file will be downloaded again. This cannot happen until host H1 restarts. Now consider a situation where there is a standby host H2 for the host H1. H1 and H2 monitor the health of each other by heartbeat messages (like SCTP). If H2 detects the failure of H1, then H2 takes over. This implies that all resources assigned to H1 are now reassigned or taken over by H2. The host H1 and H2 transmit data between each other when any one of it crashed. Throughout the data transmission process, heart beat chunk is exchanged between the hosts when one of the host crashes. In particular, the IP addresses that were originally assigned to H1 are assigned to H2. In this scenario, movement of the TCP connection between H1 and S to a connection between H2 and S without disrupting the TCP connection is achieved. Distant server S is not aware of any changes going on at the clients. digital.library.unt.edu/ark:/67531/metadc3288/
The Influence Of Jazz On Timbre In Selected Compositions For Solo Trombone
A significant body of solo literature for the trombone has been written in the last fifty years that draws as much from the jazz tradition as from that of European classical music. While much attention has been paid to these works' use of characteristic jazz rhythms, harmonies and melodic inflections, there has been little focus on timbre, the musical element that perhaps most readily distinguishes jazz from other styles of Western music. This paper focuses on the important role jazz timbres should play in a performer's interpretation of those works that are significantly influenced by jazz. It includes explorations of the significant differences in concepts of timbre between European classical music and jazz, some of the ways in which these timbral differences are produced, and methods by which performers can develop the skills necessary to produce these varied timbres. Particular attention is paid to the importance of timbre to idiomatically appropriate performances of two significant works from the solo trombone repertoire, Robert Suderburg's Night Set (Chamber Music III) and Richard Peaslee's Arrows of Time. digital.library.unt.edu/ark:/67531/metadc3361/
The influence of klezmer on twentieth-century solo and chamber concert music for clarinet: with three recitals of selected works of Manevich, Debussy, Horovitz, Milhaud, Martino, Mozart and others.
The secular music of the Eastern European Jews is known today as klezmer. Klezmer was the traditional instrumental celebratory music of Yiddish-speaking Ashkenazi Jews who eventually populated the Pale of Settlement, which encompassed modern-day Poland, Lithuania, Ukraine, Belarus and Romania. Due to the rise of oppression and expulsion, many klezmer musicians or klezmorim immigrated to the United States between 1880 and the early 1920s. These musicians found work in klezmer bands and orchestras as well as Yiddish radio and theater. Some of the most influential klezmorim were clarinetists Naftule Brandwein and Dave Tarras who helped develop an American klezmer style. While the American style flourished, the popularity of pure klezmer began to diminish. As American-born Jews began to prefer the new sounds of big band and jazz, klezmer was considered old-fashioned and was in danger of becoming a lost art form. During the early 1970s, a reawakening study of klezmer developed. Henry Sapoznik, Lev Liberman and Andy Statman were instrumental in creating a klezmer revival in the United States. At the same time, Argentinean-born Israeli clarinetist Giora Feidman was popularizing klezmer in Europe. Klezmer had again become popular and the revival's impact on the concert hall was inevitable. Even though klezmer has existed for centuries, composers have only recently included klezmer elements in their concert works. Characteristic modes (Freygish and Misheberakh), forms (freylekhs and doinas), instrumentation, and rhythms all contribute to create a unique style. Three musical works for clarinet are examined in the dissertation: Simeon Bellison's Four Hebrew Melodies in form of a suite, Simon Sargon's KlezMuzik and David Schiff's Divertimento from Gimpel the Fool. Although the compositions reveal different approaches to the elements, the klezmer influence is evident in each of them. An appendix of clarinet klezmer influenced concert works is included. digital.library.unt.edu/ark:/67531/metadc3355/
Integrating life cycle analysis and the ecological footprint calculator to foster sustainable behaviors
Access: Use of this item is restricted to the UNT Community.
Many tools have been developed to assess global, national or regional sustainable development policies. However, as governments develop sustainable policies, individuals must also feel empowered to affect their personal impact on the planet. This thesis integrates three sustainability concepts that lend themselves to individual sustainability: The natural step, life cycle assessment, and the ecological footprint. TNS serves to provide the meaning and substance toward sustainable development. LCA helps provide the framework for assessing sustainability. The EF calculator determines the driving components and measures the qualitative decisions made through TNS and LCA. From the analysis of the household footprint calculator a simplified footprint calculator was developed to assist individuals and communities in setting benchmarks and goals as they move away from over-consumption and towards a sustainable lifestyle. digital.library.unt.edu/ark:/67531/metadc3294/
Intrinsic Religious Orientation and Mental Health in Later Life
This dissertation research project was conducted to investigate religion as a coping resource in later life. The major proposition of the study was that intrinsic religious orientation is positively associated with mental health in late life. A forty three-item questionnaire was distributed to residents of four independent retirement communities resulting in a sixty-six percent return rate. The convenience sample of 214 individuals, with a mean age of 81.94 years, consisted of 156 female and 58 male respondents. Intrinsic religious orientation was held as the independent variable, while mental health was the dependent variable. Stress vulnerability characteristics were held as control variables including age, gender, education, stressful life events, marital status, perceived social support, and physical health. The zero order correlation between the independent and dependent variables was r = .128, sig. = .034 (1 tailed). When all control variables were entered, the relationship between intrinsic religious orientation and mental remained, r = .116, sig. = 046 (1 tailed). Regression analysis produced three predictors of mental health for females: stressful life events, age, and intrinsic religious orientation. Intrinsic religious orientation did not significantly change the relationship between stressful life events and mental health. A highly narrow variability in the sample limited stronger results. Findings indicate the importance of further investigation into religion as a coping resource, especially among older females. digital.library.unt.edu/ark:/67531/metadc3274/
An Investigation into Motivations of Instructors Teaching Business and Technical Internet-Based Courses at Two-Year Colleges
This research was conducted to determine why two-year community college instructors teach over the Internet. By understanding why these instructors teach over the Internet, colleges can recruit more instructors to teach using the Web thus allowing colleges to offer more Internet courses. They can also use the information to keep the instructors who are currently teaching over the Internet satisfied, and motivate them to continue to teach. To gather this information, a questionnaire was created and evaluated for reliability and validity during a pilot study. It was then sent to those instructors who taught over the Internet, and had their e-mails available on their campus Website. A 30.5% response rate (N=100) was achieved. The survey was divided into two sections, a demographics section and a Likert scale dealing with motivation. The Likert scale had six choices ranging from strongly agree to strongly disagree and 31 statements. The demographic data were reported and summarized. The Likert items were examined using factor analysis techniques, and a number of components were discovered. Eight components, made up of the 31 variables from the Likert scale were found using the factor analysis. The eight components in order are labeled: Technical and Computer Challenges, School Promotion, Student Preferences, Personal Benefits, Receiving Computerized Assistance, Growth and Knowledge, Textbook Company Assistance, and Pay. digital.library.unt.edu/ark:/67531/metadc3307/
Investigation of Lead Hydrolytic Polymerization and Interactions with Organic Ligands in the Soil/Sediment-Water Environment
The objective of this research was to investigate lead speciation in the soil/sediment-water environment and to better understand how the species affect lead mobility under different environmental conditions. The research involved both field soil and sediment samples as well as standard lead solutions. Field samples were fully characterized and extracted by aqueous and organic solvents. The results were compared and evaluated with the metal speciation model, MINTEQA2. Hydrolytic polymerization and organic complexation studies were conducted with standard lead solutions under controlled experimental conditions. Results of the field samples showed that pH, dissolved cations, ionic strength, dissolved organic matter, and nature of the soil/sediment matrix play major roles in the distribution and mobility of lead (Pb) from contaminated sites. In the aqueous equilibration experiment, the magnitude of Pb2+ solubilization was in the order of pH4>pH7>pH9. The results were in good agreement with MINTEQA2 predictions. An important finding of the research is the detection of Pb polymerization species under controlled experimental conditions. At pH 5.22, Pb polymeric species were formed at rate of 0.03 per day. The role of Pb complexation with organic matter was evaluated in both field and standard samples. Different methodologies showed three types of organically bound Pb. A very small fraction of Pb, in the ppb range, was extractable from the contaminated soil by polar organic solvents. Sequential extractions show that 16.6±1.4 % of the Pb is organically complexed. Complexation of Pb with fulvic acid provided new information on the extent of Pb association with soluble organic matter. The overall results of this research have provided new and useful information regarding Pb speciation in environmental samples. The results, in several instances, have provided verification of MINTEQA2 model's prediction. They also revealed areas of disagreement between the models prediction and the experimental results. A positive note regarding the experimental work done in the research is the verification of the mass balance in all the repeated experiments. digital.library.unt.edu/ark:/67531/metadc3314/
Investigations of Thermochemistry and the Kinetics of H Atom Radical Reactions
Access: Use of this item is restricted to the UNT Community.
The thermochemistry of several species, and the kinetics of various H atom radical reactions relevant to atmospheric and combustion chemistry were investigated using ab initio theoretical techniques and the flash photolysis / resonance fluorescence technique. Using ab initio quantum mechanical calculations up to the G3 level of theory, the C-H bond strengths of several alkanes were calculated. The bond strengths were calculated using two working reactions. From the results, it is apparent that the bond strengths decrease as methyl groups are added to the central carbon. The results are in good agreement with recent experimental halogenation kinetic studies. Hydrogen bond strengths with sulfur and oxygen were studied via CCSD(T) theory, together with extrapolation to the complete basis set limit. The results for the bond dissociation energies (ground state at 0 K, units: kJ mol-1) are: S-H = 349.9, S-D = 354.7, HS-H = 376.2, DS-D = 383.4, and HO-H = 492.6. These data compare well with experimental literature. The rate constants for the isotopic reactions of H + H2S, D + H2S, H + D2S, and D + D2S are studied at the QCISD(T)/6-311+G(3df,2p) level of theory. The contributions of the exchange reaction versus abstraction are examined through transition state theory. The energy of NS was computed via CCSD(T) theory, together with extrapolation to the complete basis set limit. The results were employed with three working reactions to find ΔfH0(NS) = 277.3 ± 2 kJ mol-1 and ΔfH298(NS) = 278.0 ± 2 kJ mol-1. This thermochemistry is consistent with, but much more precise than, earlier literature values. A kinetic study of the reaction of H + CH2CCl2 was conducted over the temperature range of 298 - 680 K. The reaction was found to be pressure dependent and results of the rate constants and their interpretation via unimolecular rate theory are presented. digital.library.unt.edu/ark:/67531/metadc3275/
Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.
This thesis contributes to modeling the dynamics of forest community response to environmental gradients and disturbances over a mountain landscape. A gap model (FACET) was parameterized for species of various forest types (Tabonuco, Colorado, Dwarf and Palm), for many terrain conditions and was modified and extended to include species response to excess soil moisture and hurricanes. Landscape cover types were defined by dominance of species of each forest type and canopy height. Parameters of the landscape model (MOSAIC) were calculated from multiple runs of FACET. These runs were determined by combining terrain variables (elevation and soil) and hurricane risk. MOSAIC runs were analyzed for distribution patterns. Geographic Information Systems software was used to process terrain variables, hurricane risk and MOSAIC model output. digital.library.unt.edu/ark:/67531/metadc3362/
Layered Double Hydroxides: Morphology, Interlayer Anion, and the Origins of Life
Access: Use of this item is restricted to the UNT Community.
The preparation of layered double hydroxides via co-precipitation of a divalent/trivalent metal solution against a base results in 1 mm LDH particles with a disorganized metal lattice. Research was performed to address these morphological issues using techniques such as Ostwald ripening and precipitation via aluminate. Another interesting issue in layered double hydroxide materials is the uptake and orientation of anions into the interlayer. Questions about iron cyanide interlayer anions have been posed. Fourier transform infared spectroscopy and powder x-ray diffraction have been used to investigate these topics. It was found that factors such as orientation, anion charge, and anion structure depended on the divalent/trivalent metal ratio of the hydroxide layer and reactivity time. The cyanide self-addition reaction is an important reaction of classical prebiotic chemistry. This reaction has been shown to give rise to amino acids, purines and pyrimidines. At cyanide concentrations similar to that expected on the early earth, hydrolysis to formamide rather than self-addition occurs. One theory to alleviate this side reaction is the use of minerals or clays that are thought to concentrate and catalyze prebiotics of interest. Layered double hydroxides have been studied as a catalyst for this reaction. digital.library.unt.edu/ark:/67531/metadc3286/
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/
Metaphors, Myths, and Archetypes: Equal Paradigmatic Functions in Human Cognition?
Access: Use of this item is restricted to the UNT Community.
The overview of contributions to metaphor theory in Chapters 1 and 2, examined in reference to recent scholarship, suggests that the current theory of metaphor derives from long-standing traditions that regard metaphor as a crucial process of cognition. This overview calls to attention the necessity of a closer inspection of previous theories of metaphor. Chapter 3 takes initial steps in synthesizing views of domains of inquiry into cognitive processes of the human mind. It draws from cognitive models developed in linguistics and anthropology, taking into account hypotheses put forth by psychologists like Jung. It sets the stage for an analysis that intends to further understanding of how the East-West dichotomy guides, influences, and expresses cognitive processes. Although linguist George Lakoff denies the existence of a connection between metaphors, myths, and archetypes, Chapter 3 illustrates the possibility of a relationship among these phenomena. By synthesizing theoretical approaches, Chapter 3 initiates the development of a model suitable for the analysis of the East-West dichotomy as exercised in Chapter 4. As purely emergent from bodily experience, however, neither the concept of the East nor the concept of the West can be understood completely. There exist cultural experiences that may, depending on historical and social context, override bodily experience inclined to favor the East over the West because of the respective connotations of place of birth of the sun and place of death of the sun. This kind of overriding cultural meaning is based on the “typical, frequently recurring and widely shared interpretations of some object, abstract entity, or event evoked in people as a result of similar experiences. To call these meanings ‘cultural meanings' is to imply that a different interpretation is evoked in people with different characteristic experiences. As such, various interpretations of the East-West image-schema exist simultaneously in mutually exclusive or competing forms, as the analysis of Gatsby and the reversal of the values of East and West in the context of colonizing and counter-colonizing attitudes suggests. digital.library.unt.edu/ark:/67531/metadc3284/
A model for developing and disseminating multimedia materials for teacher educators.
The purpose of this study was to develop a model that would enhance the development, dissemination, and adoption of educational multimedia materials. The grounded theory definition of open coding was used to analyze data collected from the 3-year Technology Leadership Web Library Project at the University of North Texas. Weekly meeting minutes, email communication, reports, notes, questionnaires, and surveys were examined to determine major factors involved in the process of product development and dissemination. From the analysis of this study, five major factors in product development and dissemination were identified. These factors were leadership, team dynamics, expert advisors, feedback, and consumers. The synthesis of the factors led to the development of the PROMOTE (process revolving around ongoing management of team and evaluative feedback) model. The PROMOTE model is based on the establishment of a system that includes leadership, development team, and expert advisors at its center. The system is tied together with well-established feedback loops for stages of evaluation. The PROMOTE model is iterative and uses consumer feedback to generate new products. The PROMOTE model differs from other product development and evaluation models both in the focus of the process and the nature of the evaluation feedback. digital.library.unt.edu/ark:/67531/metadc3342/
Music student teaching in Texas: A Delphi study of issues in the new millennium.
The preparation of prospective music educators is a very complex undertaking that culminates with the student teaching practicum. However, the music student teaching experience may have less predictable expectations and results than the curriculum that precedes the event. The two-fold purpose of this study was (a) to investigate the music student teaching practicum in the State of Texas in an effort to establish current levels of success as perceived by the music educators involved in the process and (b) to identify any potentially problematic areas which might be in need of attention or revision. Thirty-six music educators (12 university supervisors, 12 cooperating teachers and 12 student teachers) who were recently involved in the music student teaching practicum in Texas were chosen as the sample in this two-round Delphi study. The first round Delphi survey, based on related literature, achieved consensus on 79% of the 108 item responses, and 15 of the 22 unresolved items reached consensus in round two of the Delphi process. The 34 sample members who completed the study ranked a final item in the second Delphi round concerning suggestions for the improvement of student teaching. The respondents showed a very high opinion of the music student teaching practicum. However, the cooperating teachers' responses were often lower, hence the recommendation that collaborative efforts between universities and public schools be strengthened. Recommendations for improvement were also made advocating: (a) adequate rehearsal time to be afforded the student teacher, (b) expectations to be clearly defined and articulated, (c) classroom management, measurement and media, and content area reading classes to be taught by music faculty, (d) videotaping to be used in the teacher-training and student teaching process, and (e) the length of the student teaching practicum to be extended. Five additional recommendations for improvement were made in areas deemed less urgent. digital.library.unt.edu/ark:/67531/metadc3356/
Nature By Design
Access: Use of this item is restricted to the UNT Community.
Organic forms representing nature, but not particular species, are combined with elements signifying attitudes toward the natural world with an emphasis on North American culture. The viewer is encouraged to consider human effects on the environment. Aquarium Night Light and Trophy both refer to the human tendency for commercial exploitation coupled with the creation of nature images we sometimes seem to prefer over the reality of the natural world. Reliquary metaphorically connects traditional religious connotations associated with saints' relics to both a biblical injunction to use anything we needed from the natural world and our contemporary belief that exposure to nature can have beneficial effects on human mental, spiritual, and physical health. digital.library.unt.edu/ark:/67531/metadc3278/
NMR Study of n-Propyllithium Aggregates
A variable temperature 1H, 13C, and 6Li NMR study of n-propyl-6Li-lithium showed five different aggregates, similar to that in the literature as (RLi)n, n= 6, 8, 9, 9, 9. There were also a number of additional new species, identified as lithium hydride containing aggregates. Unexpectedly, a series of 13C{1H} 1-D NMR experiments with selective 6Li decoupling showed evidence for 13C-6Li spin-spin coupling between the previously reported (RLi)n aggregates and various hydride species. digital.library.unt.edu/ark:/67531/metadc3350/
Partisanship and Judicial Decision Making in U.S. Courts of Appeal
Partisanship is found in voter and Congressional behavior. Members of the federal judiciary should behave similarly. I utilize cases involving the Republican and Democratic parties from 1966 to 1997 and examine the voting behavior of federal Courts of Appeal judges. I utilize both cross tabulations and a Logit regression model to determine the likelihood appellate judges will vote for their own party and against the opposition. digital.library.unt.edu/ark:/67531/metadc3329/
Perceptions of Preservice Educators, Inservice Educators, and Professional Development Personnel Regarding Effective Methods for Learning Technology Integration Skills
This study examined educators' preferences for learning technology integration skills in order to provide the education community with justifiable data concerning the need for educator training alternatives. A survey was distributed to compare preservice educators, inservice educators, and professional development personnel's perceived effectiveness of eight training methods (N=759). The four research questions examined were: Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills? (2) Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills when categorized by age? (3) Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills when categorized by total hours of instruction? (4) Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills when categorized by locus of control? All groups were measured for similarities and differences in preferences on credit classes, workshops, open computer labs, technology personnel support, peer support, online help, printed documentation, and trial and error. In addition, those training preferences were cross-referenced with age, training hours, and the locus of control personality factor. MANOVAs and post-hoc analyses were performed for each major research question as well as trends in the data were examined. This study indicated that the most effective training methods were technical support, peer support, and credit courses. The least effective training methods were online help, printed documentation, workshops, and computer labs. Age, amount of training hours, and locus of control score did not provide as much information as did educator type when predicting training preference. Based on the findings of this study, it is recommended that educator training programs be revamped to include the methods that the educators themselves have affirmed as effective for learning technology integration skills. This assures that teachers are prepared to integrate technology into the curriculum and students are prepared for a technological society. digital.library.unt.edu/ark:/67531/metadc3316/
Performance Evaluation of MPLS on Quality of Service in Voice Over IP (VoIP) Networks
Access: Use of this item is restricted to the UNT Community.
The transmission of voice data over Internet Protocol (IP) networks is rapidly gaining acceptance in the field of networking. The major voice transmissions in the IP networks are involved in Internet telephony, which is also known as IP telephony or Voice Over IP (VoIP). VoIP is undergoing many enhancements to provide the end users with same quality as in the public switched telephone networks (PSTN). These enhancements are mostly required in quality of service (QoS) for the transmission of voice data over the IP networks. As with recent developments in the networking field, various protocols came into market to provide the QoS in IP networks - of them, multi protocol label switching (MPLS) is the most reliable and upcoming protocol for working on QoS. The problem of the thesis is to develop an IP-based virtual network, with end hosts and routers, implement MPLS on the network, and analyze its QoS for voice data transmission. digital.library.unt.edu/ark:/67531/metadc3293/
A Physiological Age-Grading System for Female Hydrellia pakistanae Deonier (Diptera: Ephydridae)
Access: Use of this item is restricted to the UNT Community.
Conflicting opinions about the effectiveness of H. pakistanae as a biological control agent for hydrilla prompt researchers to find a method for assessing the fly's success. Developing a physiological age-grading system for the fly using ovarian morphology to detect changes in reproductive activity is useful for evaluating reproductive status of the fly in field populations. Changes in the appearance of follicular relics in ovaries with oviposition provide a reliable method to estimate fecundity. Characteristics of follicular relics were used to develop a system with eight physiological age classes, three nulliparous and five parous. Changes that occur in the fat body were used to assist in classification of nulliparous females or those with low egg counts. digital.library.unt.edu/ark:/67531/metadc3280/
Preconceived Notions of Scale Relationships
I proposed in my paper to use juxtaposition of unexpected scale in my sculpture, with the expectation that it would create an unexpected tension that is visually stimulating to the viewer. I achieved this by creating disharmony in scale between an object that is perceived as miniature and an object that is perceived as gigantic within each sculpture. I then asked three questions of these sculptures: Was I able to alter the viewer's preconceived notions of the miniature and the gigantic through the manipulation of the size relationship between two objects within each sculpture? Which of these preconceived notions of the miniature or the gigantic became dominant as the main focal point in each sculpture? Did this intentional use of disharmony in scale stimulate enough of my interest to continue investigating this idea? I wrote about three sculptures that had been made for this project. The first was Manifest Destiny, a seven and a half foot tall bronze piece depicting an oil drill with a platform in the shape of the state of Texas. On the platform a gigantic bronze figure rides a miniature bronze donkey across the platform. The second bronze sculpture I wrote about was Gulliver in Suburbia; standing seven and a half feet it depicts a large bronze figure trapped within a miniature ship that stands on stilts. The last piece a wrote about was I've Outgrown This One House Town, a seven foot three inch tall bronze sculpture which depicts the frame of a house with a frame chair and bed inside. On top of the house a bronze figure sits on the roof as if it were riding a horse. I judged all three pieces to be successful and they answered all of the questions affirmatively. digital.library.unt.edu/ark:/67531/metadc3331/
A Quality of Service Aware Protocol for Power Conservation in Wireless Ad Hoc and Mobile Networks
Access: Use of this item is restricted to the UNT Community.
Power consumption is an important issue for mobile computers since they rely on the short life of batteries. Conservation techniques are commonly used in hardware design of such systems but network interface is a significant consumer of power, which needs considerable research to be devoted towards designing a low-power design network protocol stack. Due to the dynamic nature of wireless networks, adaptations are necessary to achieve energy efficiency and a reasonable quality of service. This paper presents the application of energy-efficient techniques to each layer in the network protocol stack and a feedback is provided depending on the performance of this new design. And also a comparison of two existing MAC protocols is done showing a better suitability of E2MAC for higher power conservation. Multimedia applications can achieve an optimal performance if they are aware of the characteristics of the wireless link. Relying on the underlying operating system software and communication protocols to hide the anomalies of wireless channel needs efficient energy consumption methodology and fair quality of service like E2MAC. This report also focuses on some of the various concerns of energy efficiency in wireless communication and also looks into the definition of seven layers as defined by International Standards Organization. digital.library.unt.edu/ark:/67531/metadc3289/
Radio frequency propagation differences through various transmissive materials.
The purpose of this research was to determine which of the commonly used wireless telecommunication site concealment materials has the least effect on signal potency. The tested materials were Tuff Span® fiberglass panels manufactured by Enduro Composite Systems, Lexan® XL-1 polycarbonate plastic manufactured by GE Corporation and Styrofoam™ polystyrene board manufactured by The Dow Chemical Company. Testing was conducted in a double electrically isolated copper mesh screen room at the University of North Texas Engineering Technology Building in Denton, Texas. Analysis of the data found no differences exist between the radio frequency transmissiveness of these products at broadband personal communication service frequencies. However, differences in the signal do exist with regards to the angle of incidence between the material and the transmitting antenna. digital.library.unt.edu/ark:/67531/metadc5801/
Ranges of consideration: crossing the fields of ecology, philosophy and science studies.
Access: Use of this item is restricted to the UNT Community.
Environmental issues are often complex with many different constituents operating according to a broad range of communication techniques. In order to foster negotiations, different perspectives need to be articulated in lucid ways sensitive to various viewpoints and circumstances. In my thesis I investigate how certain approaches to environmental discourse effect dialogue and negotiation. My first two chapters focus on environmental problems surrounding rangeland ecology along the U.S./Mexico border; whereas the last two chapters explore more theoretical conflicts concerning the philosophy of nature. Throughout the thesis I show the significance of nonhumans (prairie dogs, cattle, biological assessment sheets, environmental laws, etc.) in the human community. Only by considering the roles of nonhumans do we broaden and enrich the conversation between ourselves concerning environmental issues. digital.library.unt.edu/ark:/67531/metadc3292/
Rasa: Serenity, Valor, Love
The focus of this thesis is the conveyance of moods through clothes, the communication of feelings through fashion. The thesis illustrates how clothes speak, and the tools used to communicate a visual message. Three moods are used as examples: Serenity, Valor and Love. The thesis presents the author's design ability, creative personality, cultural background and technical skills. Sources of data range from personal experience to books on Cultural Studies, armor and mask making, Indian/ Asian dance and theatre, fabric design, fabric manipulation and websites on related topics. The chapters discuss background information of the author and the topic of research, and present each ensemble created to support the thesis. Through design details and photographs of the nine ensembles, the thesis demonstrates different techniques of achieving visual communication through clothes. digital.library.unt.edu/ark:/67531/metadc3347/
Reflections of Revolution: Le Figaro, Le Monde, and Public Opinion in France during the Algerian Conflict (1954-1962)
This thesis is an examination of the printed media in France (1955-1963), as represented by two mainstream newspapers: Le Monde (left-centrist) and Le Figaro (right-centrist). Using these newspapers, as well as Gallup polls recorded at the time, this study explores correlations of what was reported in newspapers and how French public opinion evolved during the course of the war. These two major sources of information are shown to have given contradictory information, thus accounting for some of the paradoxes found in public opinion polls. Specifically, the paradoxes analyzed in the study concern the Front de Libération Nationale (FLN) and the Pieds-Noirs (the European population of North Africa). digital.library.unt.edu/ark:/67531/metadc3360/
The relationship between training in learning style adaptation and successful completion of entry-level community college classes.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to determine if there was a relationship between training in learning style adaptation and successful completion of community college courses. The rationale for conducting this study was based on the need for students to learn how to adapt their learning style in order to more effectively learn in any situation. It is also important that community colleges implement strategies that assist in student retention. The learning styles of entry-level community college students were measured using Kolb's Learning Style Inventory Version 3. Students enrolled in entry-level college courses at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was no statistically significant difference in the relationship between students receiving training in learning styles adaptation and successful completion of entry-level college courses, and that students who attended a learning styles training session and those who did not attend a learning styles training session had an equal chance of succeeding in entry-level community college courses. Findings also indicated that students with Accommodating and Assimilating learning styles are less likely to successfully complete an entry-level college course than are students with Diverging or Converging learning styles, yet students with Diverging and Converging learning styles might withdraw from a course rather than risk being unsuccessful. Finally, findings indicated that students who are dissatisfied with the college course and with the instructor of the college course withdraw from college courses. digital.library.unt.edu/ark:/67531/metadc3291/
The relationship of personality traits to depression in a geriatric population.
In later life, adverse life events, disability, health problems, inadequate social support, and personality traits hypothesized to be important risk factors for depression. Sample included 35 older (65-84) physical rehabilitation patients in a large metropolitan hospital. Statistical analysis included Pearson Product Moment correlations and multiple regression results. Perceived physical health, instrumental ADLs, life satisfaction, extraversion, and conscientiousness are inversely related to depressive symptom severity; neuroticism is positively related to depressive symptom severity. Regression models predicted depressive symptom severity, PANAS negative effect and PANAS positive affect. Neuroticism, insrumental ADLs, and age are significant predictors of depressive symptom severity; neuroticism and age are signficant predictors of PANAS negative affect, while extraversion is a significant predictor of PANAS positive affect. Personality factors, level of functioning, and age are important factors relating to mood. Limitations of this study include: small sample size with special characteristics (high level of SES); incomplete personal and family history of psychiatric problems; and lack of clinical comparison sample. digital.library.unt.edu/ark:/67531/metadc3298/
Removal of selected water disinfection byproducts, and MTBE in batch and continuous flow systems using alternative sorbents.
Access: Use of this item is restricted to the UNT Community.
A study was conducted to evaluate the sorption characteristics of six disinfection byproducts (DBPs) on four sorbents. To investigate sorption of volatile organic compounds (VOCs), specially designed experimental batch and continuous flow modules were developed. The investigated compounds included: chloroform, 1,2-dichloroethane (DCE), trichloroethylene (TCE), bromodichloromethane (BDCM), methyl tertiary butyl ether (MTBE), bromate and bromide ions. Sorbents used included light weight aggregate (LWA), an inorganic porous material with unique surface characteristics, Amberlite® XAD-16, a weakly basic anion exchange resin, Amberjet®, a strongly basic anion exchange resin, and granular activated carbon (GAC). Batch experiments were conducted on spiked Milli-Q® and lake water matrices. Results indicate considerable sorption of TCE (68.9%), slight sorption of bromate ions (19%) and no appreciable sorption for the other test compounds on LWA. The sorption of TCE increased to 75.3% in experiments utilizing smaller LWA particle size. LWA could be a viable medium for removal of TCE from contaminated surface or groundwater sites. Amberlite® was found unsuitable for use due to its physical characteristics, and its inability to efficiently remove any of the test compounds. Amberjet® showed an excellent ability to remove the inorganic anions (>99%), and BDCM (96.9%) from aqueous solutions but with considerable elevation of pH. Continuous flow experiments evaluated GAC and Amberjet® with spiked Milli-Q® and tap water matrices. The tested organic compounds were sorbed in the order of their hydrophobicity. Slight elevation of pH was observed during continuous flow experiments, making Amberjet® a viable option for removal of BDCM, bromate and bromide ions from water. The continuous flow experiments showed that GAC is an excellent medium for removal of the tested VOCs and bromate ion. Each of the test compounds showed different breakthrough and saturation points. The unique design of the continuous flow apparatus used in the study proved to be highly beneficial to assess removal of volatile organic compounds from aqueous solutions. digital.library.unt.edu/ark:/67531/metadc3285/
A Security Model for Mobile Agents using X.509 Proxy Certificates
Mobile agent technology presents an attractive alternative to the client-server paradigm for several network and real-time applications. However, for most applications, the lack of a viable agent security model has limited the adoption of the agent paradigm. This thesis presents a security model for mobile agents based on a security infrastructure for Computational Grids, and specifically, on X.509 Proxy Certificates. Proxy Certificates serve as credentials for Grid applications, and their primary purpose is temporary delegation of authority. Exploiting the similarity between Grid applications and mobile agent applications, this thesis motivates the use of Proxy Certificates as credentials for mobile agents. A new extension for Proxy Certificates is proposed in order to make them suited to mobile agent applications, and mechanisms are presented for agent-to-host authentication, restriction of agent privileges, and secure delegation of authority during spawning of new agents. Finally, the implementation of the proposed security mechanisms as modules within a multi-lingual and modular agent infrastructure, the Distributed Agent Delivery System, is discussed. digital.library.unt.edu/ark:/67531/metadc3320/
The Segmentation Process and its Influence on Structure in the Malheur Me Bat Masses of Obrecht and Josquin
This study examines in detail the various aspects of the segmentation process as applied by Obrecht and Josquin to the chanson Malheur me bat, especially the effect of this process on the structure of each composer's respective mass. Although musical aspects such as cadences and mode have varying degrees of influence on the structure of these two masses, the primary influence is the establishment of proportional relationships that occur as a result of the segmentation process. Sources of previous music research frequently point out that Obrecht's Mass utilizes both the Phrygian and Aeolian modes, while in Josquin's Mass the Phrygian mode is the firmly established mode throughout. Since segments in Obrecht's Mass are usually not connected to one another, strong cadences frequently occur at the end of the segments throughout. On the other hand, since the segments in Josquin's Mass are usually connected to one another, weak internal cadences frequently occur throughout, with strong cadences reserved for the end of sections. digital.library.unt.edu/ark:/67531/metadc3337/
Server load balancing.
Access: Use of this item is restricted to the UNT Community.
Server load balancing technology has obtained much attention as much business proceeded towards e-commerce. The idea behind is to have set of clustered servers that share the load as against a single server to achieve better performance and throughput. In this problem in lieu of thesis, I propose and evaluate an implementation of a prototype scalable server. The prototype consists of a load-balanced cluster of hosts that collectively accept and service TCP connections. The host IP addresses are advertised using the Round Robin DNS technique, allowing any host to receive requests from any client. Once a client attempts to establish a TCP connection with one of the hosts, a decision is made as to whether or not the connection should be redirected to a different host namely, the host with the lowest number of established connections. This problem in lieu of thesis outlines the history of load balancing, various options available today and finally approach for implementing the prototype and the corresponding findings. digital.library.unt.edu/ark:/67531/metadc3283/
Social and Economic Characteristics Related to the Immediate College Transition of Recent High School Graduates: A Study of Southwest Region TRIO Participants' College Continuation
The purpose of this study was to determine whether: 1) Southwest Region TRIO high school students between the years 1991 - 2001 continued to college immediately after high school at rates significantly different than similar population students on national and state levels; and 2) immediate college continuation for this group was a function of social and economic characteristics including race, gender, parental education, and home-care environment. The sample included 414 TRIO program participants from Texas, Oklahoma, New Mexico, Louisiana, and Arkansas. Data on the 414 participants were gathered using an existing database containing demographic and post-secondary enrollment information on study participants. The findings of this study reveal Southwest Region TRIO students during this ten-year period continued to college immediately after high school at rates not significantly different than the national low-income population of students. Results indicate that when compared to all students in the five-state southwest region, the majority low-income, first-generation TRIO population continued to college at rates not significantly different than all-income students in the region. Findings of this study also revealed select social and economic characteristics were not predictors of immediate college continuation for this group. Finally, the study showed out-of-home care environment students continued to college at significantly higher rates than in-home care Southwest Region TRIO students. digital.library.unt.edu/ark:/67531/metadc3353/
Speaking up-speaking out: What does it take to prepare early childhood professionals to advocate for children and families?
The early childhood profession regards advocacy as a professional and ethical responsibility yet little is known about advocacy instructional practices in teacher education programs. This study surveyed selected early childhood teacher educators who currently prepare undergraduate preservice professionals in two- and four-year institutions throughout the United States to identify and evaluate the existing advocacy training practices in preservice education. The study was designed to: (a) determine what leaders in the field of early childhood believe constitutes appropriate advocacy training for preprofessionals, (b) describe the advocacy activities of teacher educators, (c) determine if there is a difference in the advocacy instructional practices of two- and four-year institutions, and (d) recommend a model for advocacy in preprofessional programs. The participants included 607 teacher educators who responded to a mailed questionnaire and 14 leaders of early childhood professional organizations who participated in telephone interviews. Participants represented 48 states and all geographic regions of the United States. Results indicate that teacher educators and leaders believe advocacy instruction is important in preparation programs. The most frequently included advocacy activities are professionalism and understanding the professional role. Advocacy skills and strategies focused on public policy were included the least. Findings show that teacher educators participate in a variety of advocacy activities although few participate in public policy activities. No statistically significant differences were found between two- and four-year institutions in advocacy instructional practices. Based on study data, the researcher developed the Brunson Model for Advocacy Instruction in order to provide the profession with a consistent and sequenced approach to advocacy instruction. Recommendations for future research include: investigation of effective strategies for teaching advocacy; a study of the developmental nature of advocacy; and a study of the Brunson Model for Advocacy Instruction to determine the model's effectiveness in preparing professionals who will have the ability to speak up and speak out for children and families. digital.library.unt.edu/ark:/67531/metadc3357/
