The spallation of aluminum, chromium, and iron oxide scales is a chronic problem that critically impacts technological applications like aerospace, power plant operation, catalysis, petrochemical industry, and the fabrication of composite materials. The presence of interfacial impurities, mainly sulfur, has been reported to accelerate spallation, thereby promoting the high-temperature corrosion of metals and alloys. The precise mechanism for sulfur-induced destruction of oxides, however, is ambiguous. The objective of the present research is to elucidate the microscopic mechanism for the high-temperature corrosion of aluminum alloys in the presence of sulfur. Auger electron spectroscopy (AES), low energy electron diffraction (LEED), and scanning tunneling microscopy (STM) studies were conducted under ultrahigh vacuum (UHV) conditions on oxidized sulfur-free and sulfur-modified Al/Fe and Ni3Al(111). Evaporative deposition of aluminum onto a sulfur-covered iron surface results in the insertion of aluminum between the sulfur adlayer and the substrate, producing an Fe-Al-S interface. Aluminum oxidation at 300 K is retarded in the presence of sulfur. Oxide destabilization, and the formation of metallic aluminum are observed at temperatures > 600 K when sulfur is located at the Al2O3-Fe interface, while the sulfur-free interface is stable up to 900 K. In contrast, the thermal stability (up to at least 1100 …

This research study investigated the effectiveness of a child-centered play therapy intervention conducted by trained high school students on the behavior of preschool and kindergarten children with adjustment difficulties. Specifically, this research determined if play sessions conducted by high school students trained in child-centered play therapy skills and procedures facilitated change in the children's behaviors. The experimental group children (N=14) each received 20 weekly individual play sessions from a high school student enrolled in a Peer Assistance and Leadership class. The high school students were randomly paired with a referred child. The high school students completed 7 one-hour training sessions in child-centered play therapy procedures and skills prior to beginning the weekly, supervised play sessions. The control group (N=12) received no treatment during the study. Pre and post data were collected from parents who completed the Child Behavior Checklist (CBCL) and teachers who completed the Early Childhood Behavior Scale (ECBS). Multivariate analyses of variance of gained scored revealed statistical significance in 2 of the 4 hypotheses. Specifically, the children in the experimental group showed significant decreases in internalizing behaviors (p = .025) and total behaviors (p = .025) on the CBCL. Although not in the statistically significant range, positive trends …

Benefits for soldiers follow the formation of ancient and present day armies raised for the purpose of extending the national or state will. Veterans' benefits for defenders of the U.S. emerged during the American colonial period. College benefits began after WWII with the GI Bill of Rights. This study examines the variations in purpose for nationally established educational benefits for veterans and the singular value to the veterans of these 5educational benefits. The study begins with an overview of the history of veterans' benefits. Primary emphasis is then placed on the educational portion of the World War II Servicemen's Readjustment Act and the current educational benefit, the Montgomery GI Bill. As the purpose of awarding educational benefits changed from World War II to the latest U.S. war, the Gulf War of 1990-1991, the economic value to the individual veteran also changed. The WWII GI Bill featured an educational provision intended to keep returning veterans out of the changing economy whereas current GI Bills is intended as a recruiting incentive for an all-volunteer force. Correspondingly, the economic value to the individual veteran has changed. Data supporting this study were extracted from historical documents in primary and secondary scholarly studies and writings, …

This study examined how current family counseling/therapy programs train students to work with families with young children and made recommendations for training in this area based on recommendations of child and family therapy experts and the research and clinical literature. These recommendations explored what knowledge and skills all students should acquire versus students who want to specialize with this population. Changes to accreditation standards were also proposed as well as a description of resources to support changes in program curricula. Current training was measured by examining curricula from master's level marriage and family counseling/therapy programs accredited by the Commission on Accreditation for Marriage and Family Therapy Education (COAMFTE) and the Council for Accreditation of Counseling and Related Education Programs (CACREP) and master's level social work programs with a family-related concentration accredited by the Council on Social Work Education Commission on Accreditation (CSWE), the accreditation standards from these three organizations, course syllabi from the COAMFTE and CACREP programs, and surveys of COAMFTE and CACREP program directors (60% response rate). Recommendations for training were obtained through a qualitative analysis of quotations from the literature concerning training and through interviews of child and family therapy experts (65% response rate). The results revealed the …

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 …

The research of Stice et al. (1994) and Stice and Shaw (1994) proposed several mechanisms that may mediate the adverse effects of media exposure to the thin ideal including internalization of the thin-ideal, negative affect, and body dissatisfaction. The purpose of this study was to extend initial research of Stice and Shaw (1994) by incorporating two forms of media (e.g., TV and Magazines) to assess the effects of exposure to the media portrayal of ideal body shape on women's mood, body satisfaction, and internalization of societal values concerning attractiveness. The relation of these variables to bulimic symptomatology was examined. The current study improved upon Stice and Shaw's study (1994) by matching participants' scores on BMI, level of negative affect, and level of body satisfaction before random assignment to the experimental conditions. Female undergraduates aged 18 to 25 years participated in premeasure (N = 198) and post measure (N = 164) conditions. Results from repeated mulitvariate analysis indicated media exposure to ideal-body images demonstrated no significant changes in women's affect, body satisfaction or endorsement of the thin ideal. Indirect support for the sociocultural theory of eating disorders was provided by multiple regression analyses that demonstrated lower levels of satisfaction with size …

This study investigated relationships among hardiness, stress, and coping strategies among mid-level nurse managers in hospitals. Coping strategies were hypothesized to be positively related to stress. In addition, hardiness and its components were hypothesized to be positively related to stress and coping strategies. Demographics were hypothesized to be unrelated to stress, hardiness, and coping strategies. Both hardiness and coping strategies were hypothesized to be predictors of stress. Pearson correlation coefficients, multiple regression, and linear regression were used in data analysis. Stress was associated with specific coping strategies viz., confrontation, selfcontrolling, accepting responsibility, and escape-avoidance. High hardiness, particularly commitment and challenge, was associated with low levels of stress and with problemfocused coping strategies. By contrast, low hardiness was associated with high stress and use of emotion-focused strategies. Significant demographics, when compared to study variables, included age, experience, time with supervisors, number of direct reports, highest degrees obtained, and formal or informal higher education in management. Young nurse managers who were less experienced in nursing and management, and who had fewer direct reports, reported the highest stress levels among nurse managers. High hardiness, particularly commitment, was a strong predictor of low levels of stress; use of escape-avoidance was a significant predictor of …

The objective of this research project was to evaluate the effectiveness of the M.Div. program of Alliance Bible Seminary, Hong Kong. The research was designed for evaluation based solely upon the perceptions of the participant (graduate). The research identified and described the graduates enrolled, assessed perceived career development and attainment, and measured the degree of satisfaction experienced by the graduates who have matriculated from the degree program. A questionnaire was mailed to obtain the necessary data from the graduates of the M.Div. program of Alliance Bible Seminary. The questionnaire which was used was adapted from a previously used one used in the study of graduate educational programs. It has been tested in two other previous studies and was deemed effective. In order to verify its effectiveness in the Eastern context, a pilot test was conducted before the formal research, and the adapted questionnaire was found effective. Responses to the questionnaire were coded and the SPSS system was used to analyze the data. Tables and figures were constructed showing frequencies and significant differences where they occurred. Generally, the graduates at Alliance Bible Seminary were very satisfied with their educational experiences. Both males and females indicated that they would choose the same …

This study employed a pretest/posttest control group design to investigate the achievement of second grade Hispanic students from a predominantly low socio-economic school in a large metropolitan city. The thirty Hispanic students with the lowest scores on the Gates MacGinitie Reading Test were randomly assigned to the experimental group (n =15) or the control group (n=15). The treatment consisted of 16, 30-minute sessions of play intervention--2 times per week for 8 weeks. The providers of play therapy were school personnel trained in the principles of child-centered play therapy including tracking, reflecting feelings, and setting limits. Instruments were administered to all subjects prior to the 8 week treatment period and in the two-week period following treatment and included the GMRT, the Joseph Pre-School Primary Self-Concept Test (JPPSCST) and the Child Behavior Checklist Teacher Report Form (CBCTRF). Statistical analyses included a (t-test; 2 tail; p > .05), discriminant analysis, and cross validation. The results indicated that children who received play therapy did not achieve notably higher mean scores in reading. However, play therapy did improve the experimental group's self-concept scores and their internal behavior scores, though not significantly. All differences between the experimental and the control groups were within 1 point except …

Organizations have had difficulty managing the performance of their knowledge work teams. Many of these troubles have been linked to antiquated or inadequate performance management systems along with a scarcity of empirical research on this important human resource initiative. These problems are magnified when managing the performance of research and development teams because greater ambiguity and uncertainty exists in these environments, while projects are unique and continually evolving. In addition, performance management in R&D has only recently been accepted as important while individuals in these settings are often resistant to teams. This study represented the first step in the process of understanding relationships between performance management practices and perceptions of performance in R&D work teams. Participants were 132 R&D team leaders representing 20 organizations that agreed to complete a survey via the Internet. The survey instrument was designed to examine the relationships between performance measurement, feedback, and reward processes utilized by teams in relation to measures of customer satisfaction, psychological and team effectiveness, and resource utilization and development. The most important level of performance measurement occurred at the business unit level followed next by the individual level while team level measurement was unrelated to team performance. A simple measurement system …

Mass media such as television, video players, video games, compact disks, and the computers are commonplace in current American culture. For English as a Second Language children, television may be the only source of English in the home serving as models of grammar, syntax, story structure. An investigation was made using English as a Second Language (ESL) kindergarteners, the classroom writing center, participant-observation, teacher as researcher, and case study methodology to investigate the following questions: Do ESL kindergarten children use media in their writing? If so, how do they use media in their writing? Upon examination of the data, it was found that all these ESL children did use media in the writing process. The function and form of the media references varied from child to child. Media was a cultural context for the childrenÕs social interactions. Oral language (with and without media references) not only informed the writing for some, but also served: to initiate, participate in, and sustain social relationships with peers. Findings indicated that two case study subjects used social dialogue as a separate operation from the production of a written story. Language informed the writing but it also had a socialization function in addition to what …

Learning communities have emerged as an efficient and effective paradigm for improving undergraduate education, especially for entering freshmen. The academy has become increasingly interested in learning outcomes and student retention, especially as they are related to the assessment of various approaches to educating the whole student. Learning community pedagogy has developed through rigorous research. However, little is known about the impact of this pedagogy upon college students' cognitive development and writing aptitude. Cognitive development theory has been most significantly influenced by the work of William G. Perry, Jr. Though no theory exists which would address the stages of writing development in university students, many composition theorists suggest a correlation between cognitive development and writing aptitude. This study measured cognitive development and writing aptitude in learning community students and non-learning community students, matching them for SAT scores, high school grade point averages, gender, and ethnicity. The research questions of interest were: 1) How does participation in a learning community affect students' cognitive development; and 2) How does participation in a learning community affect students' writing aptitude? The participants were pre- and post-assessed for cognitive development, using the Measure of Intellectual Development (MID). Additionally, participants were preand post-assessed for writing aptitude, using …

In the opinion of the alumni, Doctor of Ministry programs at Dallas Theological Seminary has its strengths. The overall opinion of the D.Min. …

The overall purpose of this study was to examine how Certified Public Accountants (CPAs) perceive the potential use of assurance services to assess quality in accounting education programs. Survey questionnaires were mailed to a random sample of 250 CPAs in the north central Texas area. The questionnaire was designed to obtain demographic information and information relating to the respondents' perceptions of quality assessment of accounting education programs. An analysis of the results of this study suggest the following: CPAs consider (1) certain established criteria, such as SAT scores and faculty-to-student ratios, as effective measures for assessing quality attributes in accounting education programs and (2) traditional measures currently used for quality assessment in accounting education programs as only moderately effective by CPAs. CPAs are apparently seeking increased involvement with accounting education quality assessment and formulation of educational standards. They view the potential application of assurance services to accounting education quality as a way to offer a wider range of services to the public. CPAs perceive assurance services as a type of quality assessment that can be used to complement, but not replace, some of the more effective traditional methods, and as a way of enhancing the quality assessment process for accounting …

This study was designed to investigate the effectiveness of a filial therapy training model with high school students enrolled in a Peer Assistance Leadership (PAL) program. Specifically, this study was designed to determine the effectiveness of filial therapy in: (1) increasing observed empathic behavior with children, (2) increasing acceptance toward children, (3) increasing the ability to allow children self-direction, and (4) increasing the level of involvement with children. Additionally, this study was designed to determine the effectiveness of filial therapy in facilitating healthy parenting attitudes of nonparenting adolescents. A research question was presented to determine if a relationship exists between empathy, acceptance, involvement and allowing children self-direction and other factors considered to be healthy parenting attitudes. An Analysis of Covariance on post-test scores revealed significant findings in the high school students ability to demonstrate empathy towards children, allowing the child self direction, communication of acceptance, and involvement as measured by the Measurement of Empathy in Adult-Child Interactions (MEACI). An Analysis of Covariance on post-test scores revealed no significant changes in parenting attitudes as measured by Adult- Adolescent Parenting Inventory (AAPI-2). A Bivariate Correlation revealed a statistically significant correlation between the Empathy, Acceptance, Allowing the Child Self-Direction and Involvement scales on …

Grandparent-Grandchild Attachment as a Predictor of Psychological Adjustment among Youth from Divorced Families

This study identified the practices and procedures of instruction that is being implemented by group counseling instructors at CACREP-accredited institutions. A survey questionnaire developed by the researcher was used to gather data from 160 CACREP-accredited counseling units across the United States. The survey was designed to collect input from group instructors on how the didactic, practicum, and experiential components of the master's level group course are being implemented. Three assumptions were made in conducting this study: 1.) The majority of master's level group instructors will report that they use a didactic component in preparing students to become effective group leaders, 2.) The majority of master's level group instructors will report that they use an experiential component in preparing students to become effective group leaders, and 3.) The majority of master's level group instructors will report that they use a practicum component in preparing students to become effective group leaders. The survey questionnaire and, consequently, the results were divided into the respective sections of didactic, experiential, and practicum. The results indicated that each of these components were utilized in the instruction of master's level group courses.

This study investigated the conflict management styles of chief student affairs officers in 4-year public institutions of higher education in the Southern Association of Colleges and Schools. The data for the study were collected using Hall's Conflict Management Survey. The sample for the study consisted of 25 chief student affairs officers. The purpose of the study was to identify the conflict management style preferences of chief student affairs officers. The other variables studied to ascertain if they had an impact on the style preferences were age, gender, number of years of experience as a chief student affairs officer, ethnicity, and the size (enrollment) of their employing institution. The study found statistically significant associations (p<.05) between ethnicity and conflict management style, specifically the synergistic and win-lose styles, and between the synergistic style and age. The association between ethnicity and conflict management style could be attributed to the fact that the Caucasian group of chief student affairs officers comprised 66.7 % of the synergistic styles and 100 % of the win-lose styles. The association between the synergistic style and age could be due to the fact that the majority of the chief student affairs officers had a synergistic style, and of that …

This study was designed to examine two questions. First, does increasing Myers-Briggs Type similarity correlate with improved performance by counselor supervisor/supervisee dyads? Second, is the Communication Style Adjustment Index superior to the cognitive style scale matching procedure as a method of quantifying MBTI similarity in dyads? Sixty-eight supervisor/supervisee dyads were recruited from University of North Texas Counselor Education Master's level practicum classes. Supervisee class rankings and supervisor performance ratings were correlated with the dyads' MBTI similarity as measured by the Communication Style Adjustment Index and the cognitive style matching procedure. While none of the hypotheses were supported it was noted that there was interaction approaching significance between dyadic similarity using the Communication Style Adjustment Index and supervisor performance ratings.

This study examines the ethical beliefs and behaviors of full-time community college faculty. Respondents report to what degree they practice sixty-two behaviors as teachers and whether they believe the behaviors to be ethical. Survey participants engaged in few of the behaviors, and only reported two actions as ethical: (1) accepting inexpensive gifts from students and (2) teaching values or ethics. The participants reported diverse responses to questions about behavior of a sexual nature, but most agreed that sexual relationships with students or colleagues at the same, higher or lower rank were unethical. Additional findings relate to the presence of diversity among the faculty, using school resources to publish textbooks and external publications, selling goods to students, and an expansive list of other behaviors. Findings of this study are compared to results from earlier studies that utilized the same or similar survey instrument with teaching faculty. The study has implications for organizational policy and procedure, for faculty training and development, the teaching of ethics or values in the classroom and for future research.

This study used case studies to examine the leadership frames of female presidents of four-year, public and private, coeducational research institutions both from the Intensive and Extensive Carnegie classifications within the United States. The population (N=30) surveyed was sent the Leadership Orientation Questionnaire (Self) developed from the previous research conducted by Lee Bolman and Terrance Deal. The Bolman and Deal leadership frame theory condensed existing organizational theories into a four-frame perspective consisting of a structural, human resource, political, and symbolic frame. Bolman and Deal theorized that the ability to use more than one frame is considered to be critical to the success of leaders and intensify that leader's capacity for making decisions and taking effective actions. The Leadership Orientation Questionnaire (Self) contains five sections that include rating scales for personal demographics, the four frames, eight leadership dimensions, and management and leadership effectiveness. The research questions sought to identify the demographic characteristics and academic histories of the survey participants and the associations between these variables, the leadership frames represented among the survey participants, and how many, and which, of the four frames the survey participants use collectively. This study allowed its participants to examine their perceptions of their own leadership frames …

The purpose of this study was to determine the effectiveness of Filial Therapy training in increasing teachers of deaf and hard of hearing preschool students': 1) empathic responsiveness with their students; 2) communication of acceptance to their students; 3) allowance of self-direction by their students. A second purpose was to determine the effectiveness of Filial Therapy training in reducing experimental group students': 1) overall behavior problems; 2) internalizing behaviors; and 3) externalizing behavior problems. Filial Therapy is a didactic/dynamic modality used by play therapists to train parents and teachers to be therapeutic agents with their children and students. Teachers are taught primary child-centered play therapy skills for use with their own students in weekly play sessions with their students. Teachers learn to create a special environment that enhances and strengthens the teacher-student emotional bond by means of which both teacher and child are assisted in personal growth and change. The experimental group (N=24) consisted of 12 teachers, who participated in 11 weekly Filial Therapy training sessions (22 total instructional hours) during the fall semester at the preschool of a center for communications disorders, and 12 students chosen by the teachers as their student of focus. Teachers and students met once …

This study assessed the quality of graduate professional training in Christian education at Dallas Theological Seminary (DTS) in terms of the perceptions of program alumni. The subjects of the investigation were 780 alumni who graduated from DTS between 1984 and 2000. The Christian Education program was assessed utilizing Daniel Stufflebeam's CIPP model and alumni data collected from a survey instrument. A response rate of 65% (N=504) was achieved. The research procedure employed a non-experimental design methodology for the quantitative component and open-ended questions for the qualitative component. Most results were statistically significant at the .05 alpha level utilizing chi-square goodness-of-fit tests.

The primary focus of this study was to discover the depth of involvement with fundraising by student affairs professionals in Texas. It sought to determine the predominance of chief student affairs officers trained in development and the types of training that they received. Cooperation between student affairs divisions and development offices was also studied and whether there was a correlation between a cooperative relationship and the number of successful fundraising goals. This study includes a review of related literature on student affairs fundraising, a description of the methodology, results of the survey, conclusions, implications, and recommendations that may assist in future decision-making concerning future involvement in fundraising. The surveys were mailed to 149 four-year (public and private) institutions and two-year public institutions in Texas. The senior staff members of both the student affairs office and development office were asked to complete a survey. There was a 60.7% return rate consisting of responses from 72 development offices and 95 student affairs offices for a total of 167 usable responses. The study found that 59% of the student affairs officers had some formal training and/or on the job training. Involvement in fundraising was reported by 62.1% of the chief student affairs officers. …
