The Developmental Stages of Concern of Teachers Toward the Implementation of the Information Technology Curriculum in Kuwait
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 …

Attitudes Toward Computer Use and Gender Differences Among Kuwaiti Sixth-Grade Students
Because computer use become more and more important in the educational environment, the attitudes of students toward computer may play an important role in their learning success. This study investigated the attitudes toward computers and gender differences of sixth-grade Kuwaiti students and examined the relationships between students attitudes toward computers and school, motivation/persistence, study habits, empathy, creative tendencies, and achievement in the Informatics field. The Computer Attitude Questionnaire (CAQ), translated from the English into Arabic Language for this study, was originally developed by Knezek and Miyashita for the Texas Center for Educational Technology (University of North Texas). The CAQ was administered to a random cluster sample of 10 public middle schools: (5 boys and 5 girls schools), with a total of 562 students, (265 boys and 297 girls), in the State of Kuwait during the academic year 1999-2000. The pilot test was conducted to calculate the reliability with Cronbachs alpha = .87 for the CAQ Arabic version. This study found positive attitudes toward computer use (mean = 3.31 on 4-point Likert-scale); however, girls had significantly more positive attitudes toward computers (mean = 3.36) than did boys (mean = 3.26). It also found statistically significant correlations between attitudes toward computers and …

An Experimental Investigation on the Effects of Web-Based Instruction/Training on Cognitive and Psychomotor Learning
The purpose of this study was to investigate the effects of web-based instruction (WBI) on cognitive and psychomotor learning. The subjects of the study received two types of instructional methods, WBI (experimental group) and traditional classroom instruction (control group). Each group received 30 minutes of instruction on "Soldering a Circuit Board." The researcher chose this content subject because it involved both cognitive and psychomotor objectives, which suited the purpose of this study. It was hypothesized that there would be no significant difference between the two methods of instruction, and also that there would be no significant interaction effects between methods of instruction and gender. Forty-six subjects from a population of students enrolled in summer classes offered by the Applied Technology, Training and Development (ATTD) program at the University of North Texas voluntarily participated in this study. Random assignment of subjects was applied in this study. A subject matter expert delivered the content for both the experimental and control groups. To measure cognitive variable, a 10 item, multiple-choice test was administered immediately after instruction. To measure the psychomotor variable, a 15-item checklist was utilized by trained judges to evaluate learners performances while soldering. The 2 x 2 factorial model with interaction …

Attitudes of American School Counselor Association Members toward Utilizing Paraprofessionals in School Counseling
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 …

The Nature of the Impact of a Reading Tutoring Program on Participating Students in the Classroom: A Qualitative Study
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 …

An Evaluation of Student Learning and Engagement in a Technology-Enhanced Algebra Unit on Slope
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 of Sputtered Neutral Atoms from a Multilayer Target
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.

An Examination of Factors Related to the Cognitive and Affective Empathy Levels of Adjudicated Youth
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 …

The Paradox of the Christian Poet: George Herbert's Problematics
The thesis examines the paradoxes in Herbert's poetry and attributes the many contradictions and vacillations within The Temple to Herbert's own "spiritual conflicts" as a Christian poet. The thesis explores the poems as interconnected expressions of Herbert's dual nature as Christian-Poet. The thesis discusses over sixty of Herbert's poems, concentrating on close readings and intratextual connections. Chapter One reviews critical approaches to Herbert's poetry and outlines the study. Chapter Two examines Herbert's life and the expression of his struggles in poetry. Chapter Three discusses Herbert's poetry itself and comments on the deceptively simplistic style. Chapter Four explores the conflict between the worlds of the Christian and the poet. Chapter Five concludes that, more than merely an artistic exercise or catechistic tool, Herbert's poetry accurately records the duality of the poet's spiritual journey.

Personality Type Preferences of Juvenile Delinquents
The purpose of this study was to identify and explore personality characteristics of juvenile delinquents, to compare those characteristics with those of the general population, and determine if there are significant differences, as measured by the Myers-Briggs Type Indicator (MBTI), between the personality characteristics of juvenile delinquents and the general population. Juvenile delinquents who were adjudicated into a Texas Youth Commission facility in North Texas were subjects for this study. Participants included 186 males who ranged in age from 14 years to 20 years. Statistical analyses were performed for each of the research questions. When comparing MBTI scores of juvenile delinquents to the general population, significant differences were found on the dichotomous scales, temperaments, function pairs, and types. All type preferences are represented within the juvenile delinquent population. The MBTI can be useful in responding to the education and rehabilitation needs of juvenile delinquents. Knowledge of personality type can help caregivers meet the needs of juvenile delinquents. Understanding personality type preference can serve to provide a deeper understanding of the behaviors that lead to adjudication of juvenile delinquents. A discovery of the types of adolescents who are adjudicated could lead to preventive measures, early detection, and early intervention for students …

Robert Boyle and the Significance of Skill and Experience in Seventeenth-Century Natural Philosophy
The purpose of this study is to examine how English natural philosophers of the seventeenth centuryin particular, Robert Boyle (1627-1691) considered and assessed the personal traits of skill and experience and the significance of these characteristics to the practice of seventeenth-century science. Boyle's writings reveal that skill and experience impacted various aspects of his seventeenth-century experimental natural philosophy, including the credibility assessment of tradesmen and eyewitnesses to natural phenomena, the contingencies involved in the making of experiments, and Boyle's statements about the requisite skills of experimental philosophy in contrast to other traditions. Subtopics explored include the popularization of science and Boyle's expectations concerning the future improvement of natural philosophy.

Enrollment Management in Higher Education: From Theory to Practice
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.

Wilderness Women: Embodiment in Nature
Virginia Woolf makes clear in her book A Room of One's Own that "[A] woman must have money and a room of her own if she is to write…." This statement extends to all endeavors by women, including sport. The gap between men and women's sports is not bridged by monetary compensation. The domination of women exists in conceptual ideals and how those are expressed through our roles in this world. I use Val Plumwood's ecological feminist theory to expose the blatant masculinity imposed upon sport. I shall argue that sport is an arena of constant struggle over basic social conceptions of men and women. My endeavor is to implore traditionally masculine territory, and show sport as the domain of no single gender, but a field of simplicity and cooperation.

Who is Helping Our Children? Development of a Model for the Training of Tutors for America Reads
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 …

Measurement of Adolescent Psychopathy: Construct and Predictive Validity in Two Samples of Juvenile Offenders
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 …

Nested Well Plasma Traps
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.

A Gobber Tooth, A Hairy Lip, A Squint Eye: Concepts of the Witch and the Body in Early Modern Europe
This thesis discusses early modern European perceptions of body and soul in association with the increasing stringency of civilized behaviour and state formation in an effort to provide motivation for the increased severity of the witch hunts of that time. Both secondary and primary sources have been used, in particular the contemporary demonologies by such authors as Bodin, and Kramer and Sprenger. The thesis is divided into five chapters, including an Introduction and Conclusion. The body of the thesis focuses on religious, scientific, and secular beliefs (Ch. 2), appearance and characteristics of witches (Ch. 3), and the activities and behaviours/actions of witches, (Ch. 4). This study concentrates on the similarities found across Europe, and, as the majority of witches persecuted were female, my thesis emphasizes women as victims of the witch hunts.

Strategic Alliance Between a Bed & Breakfast Inn and a Restaurateur: Impact on Net Income of the Bed & Breakfast Inn
This study was conducted to investigate the impact of restaurant facilities, belonging to a B&B and leased to a professional restaurateur, upon the revenue of the B&B. This study assessed the physical demands placed on the B&B operator by an on-premises restaurant. Lack of sufficient data precluded proving the premise that an on-premises restaurant leased to a restaurateur would increase the income of the B&B without placing undue physical demands on the B&B operator. However, many contributing factors support the importance of a B&B having an on-premises restaurant that is leased to a professional restaurateur.

Family Rituals and Resilience: Relationship Among Measures of Religiosity, Openness to Experience, and Trait Anxiety
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, …

Examples and Applications of Infinite Iterated Function Systems
The aim of this work is the study of infinite conformal iterated function systems. More specifically, we investigate some properties of a limit set J associated to such system, its Hausdorff and packing measure and Hausdorff dimension. We provide necessary and sufficient conditions for such systems to be bi-Lipschitz equivalent. We use the concept of scaling functions to obtain some result about 1-dimensional systems. We discuss particular examples of infinite iterated function systems derived from complex continued fraction expansions with restricted entries. Each system is obtained from an infinite number of contractions. We show that under certain conditions the limit sets of such systems possess zero Hausdorff measure and positive finite packing measure. We include an algorithm for an approximation of the Hausdorff dimension of limit sets. One numerical result is presented. In this thesis we also explore the concept of positively recurrent function. We use iterated function systems to construct a natural, wide class of such functions that have strong ergodic properties.

Carbachol- and ACPD-Induced Phosphoinositide Responses in the Developing Rat Neocortex
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, …

The Effects of a Feedback Package on the Facial Orientation of a Young Girl with Autism During Restricted and Free Operant Conditions
A multiple baseline design across activities and people was used to assess the effectiveness of a feedback package on the facial orientation of a young girl with autism. During baseline, observations indicated low rates of facial orientation and high rates of gaze avoidance during conversation (restricted operant) and play (free operant) conditions. After treatment, facial orientation rates increased and gaze avoidance rates decreased to levels similar to typically-developing peers and maintained at one month follow up. These results suggest that the feedback package was effective in producing durable facial orientation across different environments and people. Possible interpretations, strengths, and limitations are discussed.
