A major concern many counselor trainees face when preparing to see their first couple-client is that of confidence because they have had little to no experience in interacting in a professional capacity with couples. Many beginning counselors experience anxiety, which can inhibit their effectiveness with clients (Scanlon & Baille, 1994). Introducing counselor trainees to a relatively non-threatening interaction with couples might reduce the initial anxiety that characterizes the neophyte counselor venturing into new clinical territory. The interaction may also enhance feelings of warmth and closeness of the couples. John Gottman's Oral History Interview (Gottman, 1999) was the protocol used in the interaction between trainee and couple. An instrument developed for this study to measure couple counseling confidence, the State Trait Anxiety Inventory (Spielberger, 1983), and the Personal Assessment of Intimacy in Relationships (Schaefer & Olson, 1981) were used to assess levels of counselor confidence, counselor anxiety, and couple intimacy, respectively. The confidence instrument and State-Trait Anxiety Inventory were administered to 37 students who were enrolled in four graduate level introductory couple counseling classes and who interviewed couples, as well as to 34 counselor-trainees who were enrolled in five graduate level counseling courses other than couple counseling and who did not …

This thesis surveys a variety of songs and arias for high soprano which feature the nightingale; examines the musical elements that symbolize, refer to, or imitate the nightingale; and compares these musical elements with transcriptions of the nightingale's song. The first chapter reviews the symbolic development of the nightingale and its role in poetry and literature. The interior chapters address a selection of musical compositions that feature the nightingale and its song. The final chapter establishes a relationship between the sound of the actual sound of the nightingale and the musical gestures created by composers to imitate the nightingale.

This study examined the effects of response restriction (blocking and protective equipment) on subsequent durations of self-injury with two female participants with developmental disabilities. First, a functional analysis was conducted with each participant to identify potential maintaining variables of the self-injury. Second, access to the response was systematically restricted in a multiple schedule restriction paradigm. A baseline extended alone was conducted without the restriction component in place as a control condition. For one participant the results suggested that response restriction may have increased subsequent durations of responding once the restriction element was removed. For a second participant responding did not appear to be affected by the restriction component.

Guided by the life course perspective, this study examined the frequency of caregiving provided by older adults to kin and non-kin. A telephone survey produced a random sample of adults 60 years of age and older, which was predominantly White, with higher income and education levels (n = 278). Bivariate and multivariate analyses tested the impact of demographic characteristics and other variables, conceptualized as physical, human, and social capital, on the frequency of caregiving. Gender, age, health, limitations, education, income, household composition, social contact, and reciprocity were analyzed in multinomial logistic regressions. Caregiving was defined as care provided to sick or disabled persons, with frequency of providing care classified as often, sometimes, and never. The majority of older adults provided at least some care to others over a one-year period, with almost one-third doing so often and only one-quarter never doing so. Most provided care to more than one person, with over one-quarter providing care to multiple friends only. Age failed to predict caregiving involvement when physical and social capital variables were considered. The odds of often providing care are higher for women, although gender did not predict those who never provided care. Having at least some college only significantly …

This thesis is an examination of "paranoid conspiracy" films, a film noir subgenre that emerged in mainstream American cinema in the early 1970s and turns on vast, shadowy conspiracies located within U.S. "power structures" (government agencies, the military, the media) and directed against the American public. Specifically, it focuses on the emergence of these films in the 1970s, their almost complete disappearance during the Reagan presidency, and subsequent reemergence in the early 1990s. Placing representative texts in the context of U.S. political and social reality of the last three decades, it analyzes the relationship between the conspiracy theory genre, the "crisis of confidence" in the American society, and the process of formation of American national identity.

The Pink Papers is a collection of three short stories and a novel in progress consisting of four chapters. Each piece is a work of original fiction. The preface addresses the female writer and the female voice in fiction. "Broken Clock" and "Pink Paper" are the stories of two girls coping with endometriosis. "Normal Capacity" looks at the loss of a dream through the eyes of a first-year law student. The novel in progress, titled Blanchard, OK, is set in a rural farming town in Oklahoma. The novel tells the stories of 24-year-old Robin, her Aunt Paula, and Paula's boyfriend, Sam.

James Sellars has established himself as one of America's foremost composers whose eclectic style reveals a wealth of influences. His artistic combination of various traditional and avant-garde techniques, along with his sensitive and expert craftsmanship has earned him an important position in contemporary American music. Sellars' compositional styles have encompassed neo-Romanticism, in his early days, through post-serialism and Dada to an eclectic, post-Romantic style utilizing popular elements including electro-acoustic techniques. His extensive catalog of over 150 compositions includes works for orchestra, opera, chorus, dance, chamber, voices with ensemble, solo voice, piano, instrumental solos, band, and media. Sellars' compositions for piano solo span a 38-year period and total 17 works, the most important of which are his six one-movement sonatas, which represent, according to Sellars, "a journey from modernism to post-modernism." Their value lies in their eclectic stylistic approaches, artistic nd technical challenges, and pianistic effectiveness. The first three sonatas, incorporating post-serial elements, fall into a modernist stylistic stance while numbers four through six, in postmodern style, contrast one another drastically. Sonata Brasileira, recalls the broad sweeping gestures of the Romantic period; Sonata V reveals the influence of the absurdist Dada movement; and the last sonata Patterns on a Field, blends …

The purpose of this study was to identify perceived barriers to faculty participation in distance education courses in a 4-year university. The literature review was divided into four general areas, each of which may act as a barrier to faculty participation; training, administrators, rewards/compensation, and faculty characteristics/demographics. The research population consisted of 570 faculty and 59 administrators from the eight UNT schools/colleges. Dr. Kristin Betts developed the survey instrument in 1998 for similar research conducted at the George Washington University. Analysis of the collected data revealed that there was no statistically significant relationship found between faculty characteristics and faculty participation in distance education. Faculty participants and administrators disagreed on which factors, from a list of 34 items, had motivated faculty to participate in distance education. Nonparticipants and administrators disagreed on which of the factors, if not available, would be barriers to faculty participation in distance education. Participants and nonparticipants disagreed regarding the level to which selected rewards and compensations had motivated faculty to participate, and the lack of which would inhibit faculty participation in distance education. Finally, 71% of the participants had participated or planned to participate in distance education training compared to only 33% of the nonparticipants. It is …

A mobile ad hoc network (MANET) is a collection of mobile platforms or nodes that come together to form a network capable of communicating with each other, without the help of a central controller. To avail the maximum potential of a MANET, it is of great importance to devise a routing scheme, which will optimize upon the performance of a MANET, given the high rate of random mobility of the nodes. In a MANET individual nodes perform the routing functions like route discovery, route maintenance and delivery of packets from one node to the other. Existing routing protocols flood the network with broadcasts of route discovery messages, while attempting to establish a route. This characteristic is instrumental in deteriorating the performance of a MANET, as resource overhead triggered by broadcasts is directly proportional to the size of the network. Bounded-dynamic source routing (B-DSR), is proposed to curb this multitude of superfluous broadcasts, thus enabling to reserve valuable resources like bandwidth and battery power. B-DSR establishes a bounded region in the network, only within which, transmissions of route discovery messages are processed and validated for establishing a route. All route discovery messages reaching outside of this bounded region are dropped, thus …

This study investigates the correlation between students' learning styles, computer competency and student satisfaction in Web-based distance learning. Three hundred and one graduate students participated in the current study during the Summer and Fall semesters of 2002 at the University of North Texas. Participants took the courses 100% online and came to the campus only once for software training. Computer competency and student satisfaction were measured using the Computer Skill and Use Assessment and the Student Satisfaction Survey questionnaires. Kolb's Learning Style Inventory measured students' learning styles. The study concludes that there is a significant difference among the different learning styles with respect to student satisfaction level when the subjects differ with regard to computer competency. For accommodating amd diverging styles, a higher level of computer competency results in a higher level of student satisfaction. But for converging and assimilating styles, a higher level of computer competency suggests a lower level of student satisfaction. A significant correlation was found between computer competency and student satisfaction level within Web-based courses for accommodating styles and no significant results were found in the other learning styles.

The primary goal of this thesis is to provide a comparative analysis of the institutional and organizational mechanisms designed to monitor and control political corruption at the national level. The paper will provide comparisons of these arraignments and control systems across three nations. The thesis will identify differences across countries in terms of organizational and institutional political corruption control mechanisms, and use the CPI index to suggest and identify those control mechanisms that appear to be present in nations with low CPI measurements. Finally, the thesis will conclude with the discussion concerning the future prospects for controlling political corruption in Turkey based on the comparative analysis described above.

Critics and audiences alike have neglected the idea of Wilde as a precursor to Beckett. But I contend that a closer look at each writer's aesthetic and philosophic tendencies-for instance, their interest in the fluid nature of self, their understanding of identity as a performance, and their belief in language as both a way in and a way out of stagnancy -will connect them in surprising and highly significant ways. This thesis will focus on the ways in which Wilde prefigures Beckett as a dramatist. Indeed, many of the themes that Beckett, free from the constraints of a censor and from the societal restrictions of Victorian England, unabashedly details in his drama are to be found residing obscurely in Wilde. Understanding Beckett's major dramatic themes and motifs therefore yields new strategies for reading Wilde.

Secure communication is the primary challenge in today's information network. In this project an efficient secret key agreement protocol is described and analyzed along with the other existing protocols. We focus primarily on Leighton and Micali's secret-key agreement without the use of public-key encryption techniques. The Leighton-Micali protocol is extremely efficient when implemented in software and has significant advantages over existing systems like Kerberos. In this method the secret keys are agreed upon using a trusted third party known as the trusted agent. The trusted agent generates the keys and writes them to a public directory before it goes offline. The communicating entities can retrieve the keys either from the online trusted agent or from the public directory service and agree upon a symmetric-key without any public-key procedures. The principal advantage of this method is that the user verifies the authenticity of the trusted agent before using the keys generated by it. The Leighton-Micali scheme is not vulnerable to the present day attacks like fabrication, modification or denial of service etc. The Leighton-Micali protocol can be employed in real-time systems like smart cards. In addition to the security properties and the simplicity of the protocol, our experiments show that in …

This project in lieu of thesis identifies successful methods of fundraising utilized by a sampling of three secondary theater arts programs from North Texas. Programs were evaluated on their ability to fund their programs and provide a quality arts education for their students. Guidelines for fundraising were developed that allow secondary theater programs to flourish without placing an additional burden on already overextended tax system. Findings were framed in a Marxist socio-economic context, seeking to find some relation between supply-side economics and the failure of certain communities to offer quality arts programs. Marxist philosophy, emphasizing the values of community and shared wealth, served to frame findings in the context of arts programs serving and enhancing their own communities.

As the United States faces a critical teacher shortage, it is important to examine all factors that may contribute to the revolving door of teacher attrition. This study explored the climate of elementary schools to determine if there was a correlation between teacher attrition and school organizational climate. Three basic research questions were addressed: 1) Is there a relationship between school organizational climate and teacher attrition? 2) Is a change in campus leadership related to school organizational climate? 3) Is there a relationship between a change in campus leadership and teacher attrition? Thirty-seven elementary schools were examined in terms of their individual teacher attrition rates and their climate survey scores. The data utilized in this study came from one school district's climate survey and teacher attrition rates for the 2000-2001 school year. The findings of this study indicate that factors of organizational climate may predict teacher attrition rates. Specifically, instructiona support may be related to teacher attrition. Major components of instructional support include principal behaviors, respect for teaching and learning, and communication with administrators. Teacher attrition was not related to principal experience. Also, principal experience was not related to factors of school organizational climate.

An extremely facile and novel method called spontaneous deposition, to deposit noble metal nanoparticles on a most stable form of carbon (C) i.e. diamond is presented. Nanometer sized particles of such metals as platinum (Pt), palladium (Pd), gold (Au), copper (Cu) and silver (Ag) could be deposited on boron-doped (B-doped) polycrystalline diamond films grown on silicon (Si) substrates, by simply immersing the diamond/Si sample in hydrofluoric acid (HF) solution containing ions of the corresponding metal. The electrons for the reduction of metal ions came from the Si back substrate. The diamond/Si interfacial ohmic contact was of paramount importance to the observation of the spontaneous deposition process. The metal/diamond (M/C) surfaces were investigated using Raman spectroscopy, scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS) and x-ray diffractometry (XRD). The morphology (i.e. size and distribution) of metal nanoparticles deposits could be controlled by adjusting the metal ion concentration, HF concentration and deposition time. XRD data indicate the presence of textured and strained crystal lattices of Pd for different Pd/C morphologies, which seem to influence the electrocatalytic oxidation of formaldehyde (HCHO). The sensitivity of electrocatalytic reactions to surface crystal structure implies that M/C could be fabricated for specific electrocatalytic applications. The research also …

The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other avenues of register development. If registers are laryngeally derived, there should be another way of register unification, which directly addresses the coordination of the laryngeal muscles. In support of this argument, this thesis investigates the teaching practices of a group of twentieth-century American voice teachers, who rely on intensity manipulation as the primary means for enhancing the register adjustments. Intensity exercises such as the messa di voce has long been practiced in historical pedagogy, but it is not until now that voice science confirmed its significance in register coordination.

I have used computer simulations to investigate the behavior of polymeric materials at the molecular level. The simulations were performed using the molecular dynamics method with Lennard-Jones potentials defining the interactions between particles in the system. Significant effort was put into the creation of realistic materials on the computer. For this purpose, an algorithm was developed based on the step-wise polymerization process. The resulting computer-generated materials (CGMs) exhibit several features of real materials, such as molecular weight distribution and presence of chain entanglements. The effect of the addition of a liquid crystalline (LC) phase to the flexible matrix was also studied. The concentration and distribution of the second phase (2P) were found to influence the mechanical and tribological properties of the CGMs. The size of the 2P agglomerates was found to have negligible influence on the properties within the studied range. Moreover, although the 2P reinforcement increases the modulus, it favors crack formation and propagation. Regions of high LC concentration exhibit high probability of becoming part of the crack propagation path. Simulations of the tensile deformation under a uniaxial force have shown that the molecular deformation mechanisms developing in the material depend on several variables, such as the magnitude of …

Three cage-functionalized polyoxacrown ethers (9, 10 and 12) and four novel cage-functionalized polyoxamonoazacrown ethers (18, 20, 25 and 29) that contain 3,5-disubstituted-4-oxahexacyclo[5.4.0.02,6.03,10.05,9.08,11]dodecane ("oxahexacyclic") moiety have been synthesized and their respective alkali metal picrate extraction profiles along with that of three analogues 13, 14 and 21 have been obtained. The observed avidities and selectivities of the host molecules toward complexation and transport of alkali metal picrates can be related to the size and shape of their respective macrocyclic cavity and the number of donor atoms. The effect of N-alkyl substitution on the complexation properties of azacrown ethers has been studied. The avidity of N-Et azacrown ethers toward complexation with alkali metal cations is generally higher than that of the corresponding non-N-alkylated hosts. However, the presence of an N-Et group appears to have a negligible effect upon their relative selectivities in their regards. The effect of pH on extraction process was studied; it was thereby determined that the alkali metal picrate extraction experiments are best performed at high pH (ca. 11-12).

On-road remote sensing has the ability to operate in real-time, and under real world conditions, making it an ideal candidate for detecting gross polluters on major freeways and thoroughfares. In this study, remote sensing was employed to detect carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxide (NO). On-road remote sensing data taken from measurements performed in six states, (Arizona, California, Colorado, Illinois, Texas, and Utah) were cleaned and analyzed. Data mining and exploration were first undertaken in order to search for relationships among variables such as make, year, engine type, vehicle weight, and location. Descriptive statistics were obtained for the three pollutants of interest. The data were found to have non-normal distributions. Applied transformations were ineffective, and nonparametric tests were applied. Due to the extremely large sample size of the dataset (508,617 records), nonparametric tests resulted in "p" values that demonstrated "significance." The general linear model was selected due to its ability to handle data with non-normal distributions. The general linear model was run on each pollutant with output producing descriptive statistics, profile plots, between-subjects effects, and estimated marginal means. Due to insufficient data within certain cells, results were not obtained for gross vehicle weight and engine type. The "year" …

Intimate partner violence is endemic in the United States. According to the American Medical Association (1992), one-fifth to one-third of women will sustain violence from a partner or ex-partner in their lifetime. The relevant literature was organized by ICD-9-CM categories. This study examined the health consequences of partner abuse in a sample of community women using a sample consisting of 564 women in three ethnic groups. Because prior research has failed to account for variations by type of abuse on health consequences, this study assessed psychological abuse, violence and sexual aggression by women's partners. To determine whether or not different types of abuse had an effect on women's health, hierarchical regression analyses were conducted. The regression equations were calculated for women within each ethnic group to facilitate identification of similarities and differences and to control for ethnic differences in risk for specific diseases. The results were consistent with past research on health consequences of abuse and extended the prior literature by showing that psychological abuse had a pervasive effect on health conditions, distress and use of health care resources. Additionally, ethnic differences emerged. As expected, ethnicity appeared to function as a moderator. Clinical implications and recommendations are made for future …

This research examined the reasons for participation in continuing professional education (CPE) and the predictive relationship of those motivational reasons to the perceived leadership effectiveness of first-line supervisors. For this study, 105 first-line supervisors were surveyed from four electric utility companies. Input was also collected from each supervisor's subordinate employees. Using the five motivational reasons for participation, collected via the Participation Reasons Scale and the effectiveness score collected using the Leader Behavior Analysis II®, regression techniques were used to asses the data. The five participation reasons of the PRS were regressed individually against the effectiveness scores to determine the extent to which leader effectiveness could be predicted by the participation reasons. In each case, the null hypothesis failed to be rejected. Regression of the five PRS reasons collectively on leader effectiveness also failed to reject the null, producing a p value of .800 and an R2 value of .023. An "all possible subsets" regression was conducted to determine whether a smaller subset of the five predictor variables might improve the predictive value of the participation reasons. No subset improved the predictive value. This study concludes that motivation to participate in CPE does not predict leader effectiveness. Thus, training organizations do …

Many children in the United States cannot read on level by fourth grade. Traditionally, teachers have delayed reading instruction until first grade. However, involving children sooner in literary activities may provide skills needed to enable them to read on grade level. The purpose for this study was to determine the extent to which daily writing in kindergarten influences the development of invented spelling and learning to read. Five teachers modeled writing with 78 kindergarten children who wrote every day or almost every day for 20 weeks. There were 51 children in an experimental group, and 27 in a control group who were given a pretest and a posttest using the Observation Study (Clay, 1993). Results from a mixed model ANOVA indicated a significant difference between the control group and the experimental group on the Dictation Task F (1, 76) = 11.76, P≤ .001 and the Writing Test F (1, 76) = 4.33, P≤ .01. Results from a z-Test of dependent proportions indicated there were significant differences in the reading levels of the control group from the pretest to the posttest (z = 7.51, P ≥ .05) because (z = 7.51, Zcv = 1.96). The experimental group results from pretest to …

The presence of deposits leading to corrosion of the steam generator (SG) systems is a major contributor to operation and maintenance cost of pressurized water reactor (PWR) plants. Formation and transport of corrosion products formed due to the presence of impurities, metallic oxides and cations in the secondary side of the SG units result in formation of deposits. This research deals with the characterization of deposit samples collected from the two SG units (unit 1 and unit 2) at Comanche Peak Steam Electric Station (CPSES). X-ray diffraction (XRD), Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) techniques have been used for studying the compositional and structural properties of iron oxides formed in the secondary side of unit 1 and unit 2. Magnetite (Fe3O4) was found to be predominant in samples from unit 1 and maghemite (g-Fe2O3) was found to be the dominant phase in case of unit 2. An attempt has been made to customize FTIR technique for analyzing different iron oxide phases present in the deposits of PWR-SG systems.
