This study evaluated 227 students attending 12 classes of the Apprentice Medical Services Specialist Resident Course. Six classes containing a total of 109 students took the Block One Tests in the traditional paper and pencil form. Another six classes containing a total of 118 students took the same Block One Tests on computers. A confidence level of .99 and level of signifi­cance of .01 was established. An independent samples t-test was conducted on the sample. Additionally, a one-way analysis of variance was performed between the classes administered the Block One Tests on computers. Several other frequencies and comparisons of Block One Test scores and other variables were accomplished. The variables examined included test versions, shifts, student age, student source, and education levels. The study found no significant difference between test administration modes. This study concluded that computer-administering tests identical to those typically administered in the traditional paper and pencil manner had no significant effect on achievement. It is important to note, however, that the conclusion may only be valid if the computer-administered test contains exactly the same test items, in the same order and format, with the same layout, structure, and choices as the traditional paper and pencil test. In …

This research study investigated the effectiveness of child-centered group play therapy with children experiencing adjustment difficulties. Specifically, this study determined the effectiveness of child-centered group play therapy in: (a) improving self-concept, (b) reducing externalizing, internalizing, and overall behavior problems, (c) enhancing emotional and behavioral adjustment to the school environment, and (d) increasing self-control of kindergarten children experiencing adjustment difficulties. Also investigated were child-centered group play therapy effects on reducing parenting stress of the parents of kindergarten children experiencing adjustment difficulties. The experimental group consisted of 15 kindergarten children who received one 40-minute child-centered group play therapy session per week, for twelve weeks. Group facilitators were play therapists who were doctoral students at the University of North Texas. The control group consisted of the 14 kindergarten students that had been assigned to the control group in Baggerly's (1999) study. Before the group play therapy sessions began and after termination of the sessions: the researchers administered the Joseph Pre-School and Primary Self-Concept Screening Test; parents completed the Child Behavior Checklist-Parent Report, Self-Control Rating Scale, Filial Problem Checklist, and Parenting Stress Index; and teachers completed the Child Behavior Checklist-Teacher Report, Early Childhood Behavior Scale, and Self-Control Rating Scale. Although the general results of …

By 2007, one half of higher education students are expected to enroll in distributed learning courses. Higher education institutions need to attract students searching the Internet for courses and need to provide students with enough information to select courses. Internet resource discovery tools are readily available, however, users have difficulty selecting relevant resources. In part this is due to the lack of a standard for representation of Internet resources. An emerging solution is metadata. In the educational domain, the IEEE Learning Technology Standards Committee (LTSC) has specified a Learning Object Metadata (LOM) standard. This exploratory study (a) determined criteria students think are important for selecting higher education courses, (b) discovered relationships between these criteria and students' demographic characteristics, educational status, and Internet experience, and (c) evaluated these criteria vis-à-vis the IEEE LTSC LOM standard. Web-based questionnaires (N=209) measured (a) the criteria students think are important in the selection of higher education courses and (b) three factors that might influence students' selections. Respondents were principally female (66%), employed full time (57%), and located in the U.S. (89%). The chi square goodness-of-fit test determined 40 criteria students think are important and exploratory factor analysis determined five common factors among the top 21 …

Rituals are an integral part of society. The focus of research on rituals has been shifting to highlight the effect rituals may produce on individual resilience and ability to function. This study examined the relationships between participation in family rituals and several conceptually related facets of the human experience, including religiosity, openness to experience, and anxiety. Participants responded to questions on an assessment instrument (Family Ritual Questionnaire) designed to measure participation in a broad variety of identified family rituals; they were grouped according to responses on that questionnaire, and the resulting groups were compared on their responses to questionnaires addressing religiosity (Religious Background and Behavior Questionnaire), openness to experience (Revised NEO Personality Inventory Openness to Experiences scale), and anxiety (State-Trait Anxiety Inventory). The four-group classification system did not produce significant differences on measures of religiosity, openness to experience, or trait anxiety. Nor were there any significant differences noted when the groups were examined on the basis of the demographic characteristics of age, gender, separation time from family of origin, or academic status. The demographic descriptive which was associated with specific group differences related to adult composition of family of origin: participants described the adults present in their families of origin, …

Signal transduction via the phosphoinositide (PI) second messenger system has key roles in the development and plasticity of the neocortex. The present study localized PI responses to individual cortical layers in slices of developing rat somatosensory cortex. The acetylcholine agonist carbachol and the glutamate agonist trans-1-amino-1,3-cyclopentanedicarboxylic acid (ACPD) were used to stimulate PI turnover. The PI responses were compared to the distribution of the corresponding PI-linked receptors in order to investigate the regional ontogeny of PI coupling to receptors in relation to neural development. The method for assessing PI turnover was modified from Hwang et al. (1990). This method images the PI response autoradiographically through the localizaton of [3H]cytidine that has been incorporated into the membrane-bound intermediate, cytidine diphosphate diacylglycerol. In each age group (postnatal days 4-30), carbachol resulted in more overall labeling than ACPD. For both agonists, the response peaked on postnatal day 10 (P10) and was lowest in the oldest age group. The laminar distribution of the carbachol PI response from P4-P16 corresponded fairly well with the laminar distribution of [3H]quinuclidinyl benzilate binding (Fuchs, 1995). However, in the subplate layer the carbachol response was strong while receptor binding was minimal. The carbachol response decreased after postnatal day 10, …

This dissertation discusses the impact David Lefkowitz and his ministry had on Dallas during the years of his ministry (1920-1949) at Temple Emanu-El in Dallas Texas, and the years following his death in 1955. The focus is on his involvement in civic activities, although his pastoral activities are also discussed. Sources include interviews with family members, friends and acquaintances, newspaper articles, journals, internet sources, unpublished theses and dissertations about Dallas and related subjects, minutes of the Temple's Board of Directors' meetings, minutes of the Central Conference of American Rabbis, minutes of the Board of Directors' Meetings of the Dallas Jewish Welfare Federation, the Temple Emanu-El Bulletins, and selected sermons, speeches and letters of David Lefkowitz. David Lefkowitz was an important figure in the history of Dallas. He taught, by precept and example, that Jews could participate fully in the civic life of Dallas. Because of his teachings, Jews made a positive difference in the development of Dallas. He has left a lasting impression on Dallas, and through his ministry and hard work, he made Dallas a better place for all its citizens.

Change is best carried out by individual teachers, and, thus, identifying and resolving teachers’ concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers’ reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers’ concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals’ peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis …

The purpose of this study was to examine the effectiveness of a technology-enhanced unit on slope in algebra. The technology used in the study was the Topological Panorama Camera (Topocam). The research questions explored the learning and transfer of knowledge about slope and the engagement level of students during Topocam learning activities. The Topocam is a computer-controlled camera that moves on a modular track while it scans a scene through a vertical slit. Students can program the speed of the camera and frequency of pictures. They then witness the results of time and motion in the image created by the camera. Data for this study were collected from a pretest/posttest, as well as from observations of indicators of engaged learning. The research population consisted of 46 students from three classes of Algebra I students. Three classroom teachers each taught a unit on slope, while a fourth teacher conducted the activities with the Topocam for all the classes. The classroom activities focused on the concept of slope as a rate of change utilizing coordinate grids. The Topocam activities involved students in collaboratively making and testing predictions about slope. The findings of the study indicate that student learning did occur with this …

Energy distribution measurements of sputtered neutral particles contribute to the general knowledge of sputtering, a common technique for surface analysis. In this work emphasis was placed on the measurement of energy distribution of sputtered neutral atoms from different depths. The liquid Ga-In eutectic alloy as a sample target for this study was ideal due to an extreme concentration ratio gradient between the top two monolayers. In pursuing this study, the method of sputter-initiated resonance ionization spectroscopy (SIRIS) was utilized. SIRIS employs a pulsed ion beam to initiate sputtering and tunable dye lasers for resonance ionization. Observation of the energy distribution was achieved with a position-sensitive detector. The principle behind the detector's energy resolution is time of flight (TOF) spectroscopy. For this specific detector, programmed time intervals between the sputtering pulse at the target and the ionizing laser pulse provided information leading to the energy distribution of the secondary neutral particles. This experiment contributes data for energy distributions of sputtered neutral particles to the experimental database, required by theoretical models and computer simulations for the sputtering phenomenon.

The purpose of this qualitative multi-case study was to explore the nature of the impact that a tutoring program, which featured preservice teachers as tutors, had on participating fifth grade at-risk students’ literacy behaviors in the classroom.The researcher served in the role of passive participant observer during the scheduled language arts period three days per week in the participating students’ classroom for a period of twenty-three weeks. Field notes were made in the classroom and coded, and audio tapes were recorded and transcribed of the tutoring sessions. Formal and informal interviews with the teacher, tutors, and participating students were conducted, transcribed, and coded. Lesson plans and reflections developed and written by the tutors were gathered and coded. Observations indicated that there were four types of reading required on a daily basis in the classroom. Assigned readings made by the teacher included narrative and expository texts. Pleasure readings were materials chosen by the students, but at certain times were teacher initiated and at other times, student initiated. The four types of reading found in the classroom were mirrored by the tutoring sessions. Students observed in the classroom could be divided into two types and four categories. Those with positive attitudes were …

The principal investigator (PI) for this study surveyed 207 American School Counselor Association (ASCA) members on their attitudes toward utilizing trained counseling paraprofessionals in school counseling. The PI also examined the relationship between participants’ attitudes and their subjective reports of the counselor-student ratios in their schools, the amount of work time they spent providing direct counseling services to students, and the extent to which their districts experienced a school counselor shortage. The participants’ mean reported counselor-student ratio (1:464.63) significantly exceeded ASCA recommendations of 1:250. Elementary counselors reported the highest counselor-student ratios while high school counselors reported the lowest. Furthermore the PI found a significant linear trend for counselor-student ratios to decrease as school level increased. The participants’ reported mean percentage of time involved in direct counseling services (61.48%) fell significantly below the ASCA recommended 70%. Elementary counselors reported the highest amount of time involved in direct counseling services while high school counselors reported the lowest. The PI also found a significant linear trend for percentages of time involved in direct services to decrease as school level increased. Over one-fourth of the participants indicated school counselor shortages existed in their districts. A majority of participants supported utilizing counseling paraprofessionals in their …

With the advent of increased juvenile delinquency in our nation, the need for prevention and rehabilitation is paramount. Juvenile delinquent acts are becoming more serious and violent with offenders perpetrating at younger ages. Analysis suggests an increase in juvenile crime in the near future (Stone, 2000). Pinpointing the cause of delinquency is an arduous task because of the many contributing factors (e.g., impulsivity, aggression, low intellect, poor family attachment, drug, and alcohol abuse). By changing the emotional deficits found in beginning delinquency, the likelihood of developing delinquent behavior may be impeded. Research indicates that adolescents who commit crimes are lacking in empathy (e.g., Aleksic, 1975; Cohen & Strayer, 1996; Ellis, 1982; Gibbs, 1987; Marcus & Gray, 1998), thus, promoting empathy may be an avenue for prevention and rehabilitation. This study examined the levels of empathy of adjudicated youth in four juvenile correctional facilities in Texas. Using the Interpersonal Reactivity Index (IRI), empathy levels of 170 youth were examined. Youth in the study demonstrated low levels of empathy. The study found that empathy levels of adjudicated youth were differentiated by incarcerating facility, IQ, type of offense, disability status, and phase level of a re-socialization training program. Age was not found to …

This thesis presents algorithms to utilize the wireless bandwidth efficiently and at the same time meet the quality of service (QoS) requirements of the users. In the proposed algorithms we present an adaptive frame structure based upon the airlink frame loss probability and control the admission of call requests into the system based upon the load on the system and the QoS requirements of the incoming call requests. The performance of the proposed algorithms is studied by developing analytical formulations and simulation experiments. Finally we present an admission control algorithm which uses an adaptive delay computation algorithm to compute the queuing delay for each class of traffic and adapts the service rate and the reliability in the estimates based upon the deviation in the expected and obtained performance. We study the performance of the call admission control algorithm by simulation experiments. Simulation results for the adaptive frame structure algorithm show an improvement in the number of users in the system but there is a drop in the system throughput. In spite of the lower throughput the adaptive frame structure algorithm has fewer QoS delay violations. The adaptive call admission control algorithm adapts the call dropping probability of different classes of …

This study examines the impact of issues of loss on adolescents. It was hypothesized that adolescents who experienced incidents of loss which were not adequately supported or processed to the point of resolution are much more likely to exhibit more angry and defiant behaviors than those who did not have such life experiences. Three instruments were used to identify loss and related impact. The first is the Interview Process, designed to identify issues of loss and screen for problematic behavior. This tool is used to qualify the participant for the study, and to designate which study group the participant will be assigned. The Family Constellation Exercise is an experiential assessment tool that exemplifies how emotionally close or distant the participant feels in relation to his or her nuclear family members. The Minnesota Multiphasic Personality Assessment - Adolescent version (MMPI-A) is used to identify behaviors and thought patterns associated with anger and defiance.The study was able to conclude that there is a strong potential for unresolved loss to negatively impact an adolescent. The study also discovered that many teenagers who do not exhibit angry or defiant behaviors have also experienced loss, yet do not act out anger. Suggestions are made as …

The dissertation consists of two parts: (1) the essay and (2) the composition. The essay elucidates the composer's creative process of the orchestral works, The Heidegger Collection. The Heidegger Collection has five movements. The titles of each movement are derived from the key philosophical concepts from Heidegger's most significant writing, Being and Time: (1) State-of-Mind, (2) Idle-Talk, (3) Moment-of-Vision, (4) Dread, and (5) Being-towards-the-End. The essay discusses the meanings of the five concepts, and explains how I express my reaction to Heidegger's thinking through music composition. The essay also discusses the essential musical language of The Heidegger Collection, such as interval cycles, polyrhythmic patterns, algorithmic elements, portamento effects, chaos theory, and oriental influence.

The purposes of this study were to determine the initial impact of the Oklahoma Library Media Improvement Grants on Oklahoma school library media programs; assess whether the Oklahoma Library Media Improvement Grants continue to contribute to Oklahoma school learning communities; and examine possible relationships between school library media programs and student academic success. It also seeks to document the history of the Oklahoma Library Media Improvement Program 1978 - 1994 and increase awareness of its influence upon the Oklahoma school library media programs. Methods of data collection included: examining Oklahoma Library Media Improvement Program archival materials; sending a survey to 1703 school principals in Oklahoma; and interviewing Oklahoma Library Media Improvement Program participants. Data collection took place over a one year period. Data analyses were conducted in three primary phases: descriptive statistics and frequencies were disaggregated to examine mean scores as they related to money spent on school library media programs; opinions of school library media programs; and possible relationships between school library media programs and student academic achievement. Analysis of variance was used in the second phase of data analysis to determine if any variation between means was significant as related to Oklahoma Library Improvement Grants, time spent in …

This study was design to determine the efficacy of intensive individual play therapy as a method of intervention for children diagnosed with insulin-dependent diabetes mellitus. The purpose of this study was designed to study the effectiveness of an intensive play therapy intervention in: a) reducing symptoms of childhood depression in children with IDDM; b) reducing symptoms of anxiety in children with IDDM; c) reducing the overall behavior difficulties in children with IDDM; d) increasing healthy adjustment in children with IDDM; e) increasing diabetic's children's adherence to their diabetic regime; and f) impacting these emotional and behavioral symptoms over time. The 15 children in the experimental group received 12, daily play therapy sessions while attending a summer camp for children with diabetes. The control group, consisting of 15 children who attended the diabetic summer camp, received no play therapy. Children and parents in both groups completed pretest, post-test and three-month follow-up data, consisting of: the Children's Depression Inventory, the Revised Children's Manifest Anxiety Scale, the Filial Problems Checklist and the Diabetes Adaptation Scale. Analysis of covariance revealed that the children in the experimental group significantly improved their adaptation to their diabetes following intensive play therapy as reflected by the Diabetes Adaptation …

The construct of psychopathy holds promise as a discriminating variable in the classification and explanation of childhood antisocial behavior. The new generation of psychopathy measures, designed to measure this construct in adolescent populations, must meet acceptable standards of reliability and validity prior to the clinical application of the construct with adolescent offenders. The purpose of this study is to examine the construct and predictive validity of adolescent psychopathy as measured by the PCL:YV, PSD, SALE, and SRP-II. Data from two samples of detained adolescent offenders (short-term and long-term detention) are utilized to investigate construct validity via MTMM. In addition, external validity indices including institutional violations (fighting, seclusions, and treatment refusals) and community supervision (probation contacts, drug testing, and re-arrests) are operationalized and measured in order to examine the predictive validity of adolescent psychopathy. Results of construct validity offer modest support for the two-factor model of psychopathy. For external validity, Factor 2 accounted for greater variance in the prediction of institutional infractions and subsequent placements in a secure facility; however, its overall predictive validity was low. The results suggest that the current measures assess psychopathic traits and behaviors which may be stable in adults but are likely to be normative and …

Earth Ascending is a composition in three movements scored for female voice, electroacoustic music, and video. Composed in the Year 2000, Earth Ascending lasts approximately sixteen minutes and was created specifically for live performance in which all three elements combine to create a sonic and visual environment. As such, no single element has greater importance than any other, with each of the three performing forces assuming a foreground role at various times throughout the work. Earth Ascending is defined by a single poem written by contemporary female British poets Jeni Counzyn, Jehanne Mehta, and Cynthia Fuller. The movements are named according to the title of each poem: Earth-Body, Light-Body; Wringcliff Beach; and Pool. The movements are separated in performance by five seconds of silence and black on the video screen. The paper accompanying the score of Earth Ascending is divided into five chapters, each discussing in detail an element central to the composition itself. The Introduction presents background information, general ideas, and approaches undertaken when creating the work. Chapters 1 through 3 investigate in detail the content of the electroacoustic music, voice, and video. Chapter 4 discusses scoring techniques, revealing approaches and methods undertaken to solve issues relating to notation …

Leadership has been studied as an essential component for success in business, government, and military environments. However, the optimal style of leadership in university settings remains unclear. Transformational leadership style has been proposed as efficient for universities, however some experts have argued that transformational leadership is actually counterproductive at academic institutions. Increasing public scrutiny of university leaders has also raised the question of presidential leadership style. One manifestation of this scrutiny is the U.S. News & World Report (USNWR) annual college ranking. To resolve the uncertainty regarding effective leadership style the present study was designed to address the following research questions: 1. Is there any relationship between a top tier ranking in the USNWR and a particular leadership style? 2. Is there agreement among top administrators at the ranked institutions regarding the style of leadership exhibited by their university president? The proposed study answers these questions through the analysis of data gathered utilizing the Multifactor Leadership Questionnaire. The survey instrument was sent to three top administrators at the top 50 ranked national universities according to USNWR. A score was derived which provided a quantitative assessment of transformational, transactional or laissez-faire leadership styles. In addition, a satisfaction score was determined. The …

This study examines pre-service teachers' attitudes toward language diversity and linguistically diverse students. Two hundred seventy-one teacher education students were surveyed to determine relative effects of demographic, mediating variables and psychosocial variables on language attitude as measured by the Language Attitudes of Teachers Scale (LATS). Independent variables include gender, age, race/ethnicity, teacher certification sought, region, psychological insecurity, cognitive sophistication, and helpfulness viewpoint. Research questions are established and methodology is outlined. A review of related literature places the study in the context of research with a broad interdisciplinary perspective and then links the study to other research relevant to the field of education. The findings of the study indicate that gender, race/ethnicity, teacher certification sought, political ideology, psychological insecurity, and cognitive sophistication contribute significantly to the variation found in attitude toward language diversity. The paper concludes with analyses and discussions of the significant variables and suggestions for application in teacher preparation.

Criteria for the confinement of plasmas consisting of a positive and negative component in Penning type traps with nested electric potential wells are presented. Computational techniques for the self-consistent calculation of potential and plasma density distributions are developed. Analyses are presented of the use of nested well Penning traps for several applications. The analyses include: calculations of timescales relevant to the applications, e.g. reaction, confinement and relaxation timescales, self-consistent computations, and consideration of other physical phenomenon important to the applications. Possible applications of a nested well penning trap include production of high charge state ions, studies of high charge state ions, and production of antihydrogen. In addition the properties of a modified Penning trap consisting of an electric potential well applied along a radial magnetic field are explored.

This study investigated enrollment management practices found in higher education. The research identified enrollment management and retention practices described in the higher education literature. These suggested practices were incorporated into a sixty-six question survey that was distributed to a random sample of colleges and universities taken from the 1999 US News and World Report of college rankings. The survey data were used to identify which of the suggested enrollment management practices were of greatest utility. First, the sixty-six items were grouped into 14 categories of enrollment management strategies. Second, the institutional responses for each category were averaged and then correlated with each institution's graduation rate. Finally, each institution's "yes" responses for the entire survey were totaled and correlated with each institution's graduation rate. This study developed a list of the 26 most frequently used enrollment management practices in higher education, and as well, identified the 10 least used enrollment management practices. Given the results of this study graduation rate is not a sufficient criterion to assess enrollment management practices at a college or university. Enrollment management strategies contribute to many institutional and student outcomes; thus, multiple indicators are required to accurately evaluate enrollment management practices.

The purpose of this research study was to examine the effectiveness of training for college work study students who participated in an America Reads program, which was designed to help at-risk children struggling with reading. Two groups participated in this research study. One group of college tutors had minimal training in reading strategies at the beginning of the study and the other group of college tutors had continuous training and feedback throughout the study. The research study sought to answer the following questions: 1) Will training for college student tutors in the area of reading, more specifically in the strategies and skills, help improve their comprehension and vocabulary? And 2) Will training for college student tutors in the area of reading, more specifically in strategies and skills, significantly improve the comprehension and vocabulary scores of the children being tutored? This was a quasi-experimental research design, used to examine the effectiveness of training college students participating in the America Reads program. The tutors were pre-and post-tested, measuring both their vocabulary and comprehension knowledge at the beginning and the end of the study. The children being tutored were also pre- and post-tested, measuring both their vocabulary and comprehension knowledge at the beginning …
