Subsidy ("Vanity") Publishing Among American College and University Faculty

Subsidy ("Vanity") Publishing Among American College and University Faculty

Date: May 1991
Creator: Alahmad, Husam I. (Husam Ibrahim)
Description: The problem of this study was subsidy ("vanity") publishing among college and university faculty. The purpose of the study was to estimate the extent to which postsecondary faculty use subsidy presses for the publication of their scholarly writings and the professional reasons for which academicians choose these presses to publish their works, viz., tenure, promotion, or salary increase. An additional purpose was to compare the subsidy publication experiences of faculty according to the types of institutions which employ them. The study involved 11 national subsidy publishers and 1,124 subsidy-published authors throughout the United States. Subsidy-published authors were identified occupationally as faculty by their appearance in the 1990 edition of The National Faculty Directory. The subjects in this study consisted of (a) faculty members listed in The National Faculty Directory. 1990 who are (b) known to have used subsidy presses for publishing their writings. A major finding of the study was that the proportion of vanity-published authors who are college and university faculty was small. Twenty-seven percent of the faculty whose books had been published by subsidy presses indicated that they had written and published in order to earn salary increases. Another 23% indicated that they had their books published to ...

Reactions and Learning as Predictors of Job Performance in a United States Air Force Technical Training Program

Date: December 1999
Creator: Boyd, Steven W.
Description: This study is based on Kirkpatrick's (1996) four level evaluation model. The study assessed the correlation between and among three levels of data that resulted from evaluation processes used in the U.S. Air Force technical training. The three levels of evaluation included trainee reaction (Level 1), test scores (Level 2), and job performance (Level 3). Level 1 data was obtained from the results of a 20 item survey that employed a 5-point Likert scale rating. Written test scores were used for Level 2 data. The Level 3 data was collected from supervisors of new graduates using a 5-point Likert scale survey. The study was conducted on an existing database of Air Force technical training graduates. The subjects were trainees that graduated since the process of collecting and storing Levels 1 and 2 data in computerized database began. All subjects for this study graduated between March 1997 and January 1999. A total of 188 graduates from five Air Force specialties were included. Thirty-four cases were from a single course in the aircrew protection specialty area; 12 were from a single course in the munitions and weapons specialty area; and 142 were from three separate courses in the manned aerospace maintenance specialty ...

A Cost-Benefit Analysis of the Implementation of Texas House Bill 72 in Selected Texas Public School Districts

Date: May 1990
Creator: Bradford, Ronald W. (Ronald Wayne)
Description: This study was conducted to analyze the effect of implementation of Texas House Bill 72 on budgets of selected Texas public school districts and to ascertain educational benefits to students derived from implementation of the bill as perceived by superintendents. Questionnaires were sent to superintendents of the Region 10 Education Service Center to determine perceived educational benefits to students. A demographic data sheet provided information for classifying respondents by educational experience, superintendent experience, and district enrollment classifications. Sixty-two districts responded. Official public school budget data for each district were analyzed for fiscal years 1983 through 1986 as were data from the questionnaire. Overall statistical information was gleaned through CONDESCRIPTIVE. Mean total expenditures, mean total tax rate, and state fiscal aid data were compiled, tabulated, and reported for each enrollment classification and entire sample. In addition, a t-test between the difference of two independent means at a probability level of .05 was applied. The two independent means were the averages of data for the two years prior to and after implementation of the law for expenditures, tax rates, and state fiscal contributions. Data comparing local and state expenditures were compiled, tabulated, and reported for each group to compare local and state ...

Parent Adaptive Doll Play with Children Experiencing Parental Separation/Divorce

Parent Adaptive Doll Play with Children Experiencing Parental Separation/Divorce

Date: December 1990
Creator: Brennan, Carol A. (Carol Ann)
Description: Parent Adaptive Doll Play, a technique in an early stage of development, is designed for use by parents in assisting their young children to cope with the stresses of parental separation/divorce. The effects of technique implementation by parents of three- through six-year-old children were investigated. Data was collected before and after parents received training and implemented the technique over an eight-week period. Parents completed the Child Behavior Rating Scale, Burks' Behavior Rating Scales, the Parenting Stress Index, and the Parental Attitude Scale. Twenty-two parents, reporting marital separation through separation and/or divorce, within 18 months prior to the beginning of the study, and reporting more than 50 percent physical custody of a three- through six-year-old child qualified for participation. Twelve children were experimental subjects and ten were control subjects. To determine differences between groups, a one-way analysis of covariance was performed on each post test variable. Positive differences were calculated in several areas of child behavior by parents of subjects in the experimental group. No significant differences between groups were found in any area of child behavior. The score which most closely approached significance, however, was found in the Burks' Behavior Rating Scale area of poor anger control.

Academic, Behavioral, and Social Competency Characteristics of Non-Handicapped, Learning Disabled, and Emotionally/Behaviorally Disordered Adjudicated Juveniles

Academic, Behavioral, and Social Competency Characteristics of Non-Handicapped, Learning Disabled, and Emotionally/Behaviorally Disordered Adjudicated Juveniles

Date: August 1990
Creator: Campbell, Robert E. (Robert Eugene)
Description: The juvenile justice system is society's response to juvenile misconduct. In spite of numerous federal, state, and local programs, the problem of juvenile delinquency persists. An increasing number of juveniles are being taken into custody and placed in institutional settings. Although juvenile delinquents share a number of common general characteristics (e.g., sex, minority, lower socioeconomic status, a history of school failure), they are not a homogeneous group. Effective educational interventions with delinquent juveniles can meet their unique academic, vocational, and social skills deficits. Handicapped juveniles are disproportionately represented among juvenile correctional facility populations. The identification of handicapped juveniles among delinquent populations is compounded as they share many of the same general characteristics. Federal statutes require individualized educational programs for all handicapped juveniles. This research investigated academic, behavioral, and social competencies of non-handicapped and handicapped adjudicated youth. Specifically, this investigation assessed measures of academic performance, classroom behavior, self-esteem, and social behavior. ANOVA indicated statistically significant differences between non-handicapped, learning disabled, and emotionally/behaviorally disordered adjudicated juveniles in reading achievement, mathematics achievement, and teacher generated measures of classroom behavior.

The Relationship of Self-Concept and Study Habits of At-Risk Students as Measured by the Piers-Harris Children's Self-Concept Scale and the Survey of Study Habits and Attitudes

Date: August 1990
Creator: Carpenter, Robert M. (Robert Marshall)
Description: The purpose of this study was to determine the relationship between self-concept and study habits among different subgroups of 9th grade at-risk students. The study included the administration of two independent measures: The Piers-Harris Self-Concept Scale and the Survey of Study Habits and Attitudes. Other data were self-reported by the students. The five subgroups selected in this study were: (1) male and female, (2) white and non-white, (3) socioeconomic groups determined by eligibi1ity in the Free/Reduced Lunch Program, (4) retained and non-retained students, and (5) participants and non-participants in school activities. Raw scores from the self-concept scale and study habits survey were converted into percentile scores. A correlation coefficient was calculated for each subgroup. The significance of the two correlation coefficients was tested using Fisher's Zr transformation. Of the five hypotheses tested at the .05 level, all were rejected. Major findings of the study verify other research regarding characteristics of at-risk students. Also, more than half of the subjects had deficient study habits but only a small percentage (19,5V#) had signif icant ly low self-concept scores. In addition, at-risk students who participate in school activities had higher self-concept scores and study habits scores than non-participating at-risk students. It was concluded ...

A Study of the Influences Upon Pre-Service Teachers' Pre-Planning, Lesson Planning, and Bases for Interactive Decision Making During Lesson Implementation

Date: May 1990
Creator: Chang, Tony Hong-Jee
Description: The primary objective of this study was to describe the influences upon pre-service elementary teachers' preplanning, lesson planning, and bases for interactive decision making during their lesson implementation. Six female volunteer pre-service elementary teachers from the teacher preparation program at the University of North Texas planned and taught three separate lessons in one of the following content areas-social studies, language arts, mathematics, science, and safety, at six different schools in the north Texas area. Each element of the lesson plans (18 total) was classified for analysis. Following the presentation of each lesson, the pre-service teachers were asked to use the repertory-grid technique to sort out five decisions from a series of lesson-implementation decisions which had been observed and recorded by the investigator. Then the six pre-service teachers were interviewed by the investigator using the stimulated recall technique. During the interview, each decision was discussed with the pre-service teachers, who responded to seven structural questions that probed their concerns, attitude, type of concerns, and number of concerns. The six pre-service elementary teachers possessed some ability to direct students in their classroom learning using activities and instructional knowledge. This enabled them to notice individual student performance and that of students in the ...

Development of a Discouragement Scale for Adults with Normative Data for Gay Males

Development of a Discouragement Scale for Adults with Normative Data for Gay Males

Date: December 1996
Creator: Chernin, Jeffrey N.
Description: According to Alfred Adler, founder of Individual Psychology, a feeling of inferiority is in some degree common to all people. People who are unable to overcome these inferiority feelings by striving for cooperation may become discouraged. Although there are three scales to measure social interest, no scales measuring discouragement for adults was found. Additionally, Adler held basic assumptions regarding homosexuality, and the findings suggest that the assumptions should be reexamined. The purpose of this study was twofold. First, three University of North Texas candidates developed a discouragement scale for adults 18 years of age and older, known as the Discouragement Scale for Adults (DSA). Discouragement was examined relative to the five life tasks. Second, this candidate normed the instrument for the scores of gay male subjects and compared it to the scores of the other subject groups. Since the emphasis was on developing the instrument and norming it for various subject groups, no hypothesis was developed. Data was collected on three subject groups, known as the general norm subjects, the discouraged subjects, and the gay male subjects. Analyses were performed on the scores. Among the analyses, it was found that gay male subjects were slightly more discouraged than the general ...

A Comparative Analysis of the Effects of Video-Based versus Live Presentation Staff Development on Teachers' Cognitive Learning and Attitudes

Date: December 1995
Creator: Cox, Alan R. (Alan Ray)
Description: The problem of this study was the identification of effective and efficient means of providing quality staff development for reading instruction within a school-district setting. The study investigated the comparative effectiveness of two staff development delivery systems measured by 1) a cognitive test of a school district's reading program and 2) an affective measure of teacher attitudes toward staff development. The sample was drawn from the teacher population of a large urban school district. The 46 subjects were elementary school teachers in grades K-5 randomly divided into two groups: Group A (videotape with a trained on-site facilitator) and Group B (face-to-face live presenter). Participants in the study received training using "The Fort Worth Reading Program," a staff development program designed by the researcher. In addition to the presentation of content information, which is the central component, the program features small group discussions, off-line activities, and question and answer periods. Both groups received the same treatment with the following exception. A central component to the Group A training was the presentation of content information in a videotape format. Group B did not view the videotape, but received the same information via live presenter. Two instruments developed by the researcher were used ...

An Ethnographic Study of the Use of Puppetry with a Children's Group

An Ethnographic Study of the Use of Puppetry with a Children's Group

Date: August 1990
Creator: Deniger, Marcy M. (Marcy Marble)
Description: This study utilized an ethnographic methodology to examine and describe the various aspects and processes occurring in a children's group as the members created their own puppets and accompanying puppet plays. Individual and interactive behavior patterns were isolated and analyzed as a means of gaining an in depth understanding of the puppetry process. The puppetry process, in turn, was viewed in terms of information it provided regarding the individual members and the group process. The facilitative and non-facilitative aspects of the procedure were delineated. The adult leader met with a group of six boys, in grades four and five, for 12 one-hour sessions in which they made puppets and then created puppet plays around issues that they had articulated as problems. The group sessions were videotaped and transcribed. The transcriptions were coded in an effort to extensively analyze the puppetry process and the group process, and the ways in which the two processes interacted. An independent observer/rater was utilized in order to provide some validity for the researcher's reported results. The puppet-making task appeared to offer an opportunity for individuals to begin to come together in a common, but individual task. Characteristic styles and individual personality dynamics were evidenced. General ...

Development of an Expert System to Teach Diagnostic Skills

Date: August 1990
Creator: Elieson, S. Willard (Sanfred Willard)
Description: The primary purpose of the study was to develop an expert system that could C D perform medical diagnoses In selected problem areas, and C2) provide diagnostic Insights to assist medical students In their training. An expert system Is a computer-based set of procedures and algorithms that can solve problems In a given domain. Two research questions were proposed. The first was "Given a problem space defined by a matrix of diseases and symptoms, can a computer-based model be derived that will consistently perform accurate and efficient diagnoses of cases within that problem area?" The second question was "If the techniques derived from the model are taught to a medical student, is there a subsequent improvement of diagnostic skill?" An expert system was developed which met the objectives of the study. It was able to diagnose cases in the two problem areas studied with an accuracy of 94-95%. Furthermore, it was able to perform those diagnoses in a very efficient manner, often using no more than the theoretical minimum number of steps. The expert system employed three phases: rapid search by discrimination, confirmation by pattern matching against prototypes, and elimination of some candidates (impossible states) by making use of negative ...

The Influence of the First Amendment on Academic Freedom

The Influence of the First Amendment on Academic Freedom

Date: May 1990
Creator: Ferdon, Douglas Robert, 1945-
Description: Academic freedom has gone through three distinct eras yet each era overlaps a great deal with the one following it. The first era was the bureaucratic. It was exemplified by the negotiations between administrators and professors in the 1920s. The American Association of University Professors and the American Association of Colleges began cooperating and a hierarchical structure emerged, with the tenured professor at the top of the faculty. The second era was the political era and it was mainly a result of loyalty oaths, which began after the first World War and then escalated again during the 1930s when communism became a major concern. The political era then gave way to the legal era when the first academic freedom cases went to the United States Supreme Court in the 1950s. The first cases were the result of political pressures that became legal pressures. Most of the early court cases were based on communism. The legal era has produced changes. There are now more rights; for students and teachers of all levels, including pre-college levels, are guaranteed some academic freedom rights. However, the First Amendment and academic freedom are not synonymous because a professor usually cannot win a case based solely ...

Date: August 1990
Creator: Gardner, Kent Lee
Description: This study examined the academic achievement of national social fraternity pledges compared to non-fraternity students at the University of Texas at Arlington. It was done to determine whether significant differences existed between the grade point averages of pledges of social fraternities and those of students who did not pledge a social fraternity, and to determine whether significant differences existed among fraternities when compared with each other with respect to academic achievement. This study was meant to provide a research design that could be used by other colleges and universities with fraternities to conduct the same comparison of academic performance. In the fall semester of 1989, 164 pledges were selected as the population for the study to be matched with non-fraternity students based on Scholastic Aptitude Test (SAT) scores, age, sex, classification, academic major, and number of hours attempted. A T-test of like groups was performed on the entire population with no significant difference found at the .05 level between all the fraternity pledges and all the matched pairs. A T-test of like groups was performed on the pledges from each separate organization and there was a significant difference among three of the fraternities. Two of the fraternities had significantly higher ...

Date: August 1990
Creator: Goldstein, Roberta Eisman
Description: This study examined the effects of Systematic Training for Effective Parenting (STEP) on affection, communication, and relationship between elderly parents and their assisting adult children. Twenty-eight pairs of parents and children were randomly assigned to treatment or control groups. Subjects took Quinn's Family Life Questionnaire as pre-, post-, and follow-up tests. Parents and children in the treatment groups attended a four-session STEP workshop. No significant differences were found on the 2 x 2 analysis of variance for repeated measures for the parents or adult children. Quinn's affection and relationship variables approached significance for the parents over time. His variable affection approached significance for the children over time, irrespective of group. Agreement approached significance for children in the treatment group. The results for the parents regarding affection suggest that the study may have emphasized their feelings of trust. Although the data for relationship approached significance, it was negative, indicating that parents in the treatment group may have reduced their interaction with their assisting children perhaps because they were learning new communication skills. The data for the children regarding affection approached significance, but it was negative, suggesting they felt free to question their feelings about themselves and their parents. The results for ...

Perceptions of the Sudanese Professional Working in Saudi Arabia on Migration and Economic Development of the Sudan

Date: March 1990
Creator: Hamid, Adil A. (Adil Abdelaziz)
Description: The brain drain emerged as a phenomenon in the Sudan in the early 1970's when a change in the political system was followed by a change in the economic situation. The oil price increases created a dynamic process that led to attractive employment conditions in the petroleum producing countries such as Saudi Arabia and to depressed economic conditions in the developing countries like the Sudan. The purposes of the study are to (a) obtain information on the Sudanese professionals working in Saudi Arabia, (b) determine what major factors influence their migration, and (c) to develop policy recommendations on the flow of migration from the Sudan. The population of this study were Sudanese professionals living in Saudi Arabia. Data were generated through surveying a sample of 300 subjects selected randomly from the defined population. A survey questionnaire based on the research questions was developed for this study. Data from 263 respondents were analyzed. The findings of the study suggest that the majority of the Sudanese professionals working in Saudi Arabia are male, between 30 to 40 years of age. They have many years of experience and a high level of qualifications. The factors that led to their migration are: (a) high ...

A Monte Carlo Study of the Robustness and Power Associated with Selected Tests of Variance Equality when Distributions are Non-Normal and Dissimilar in Form

Date: August 1990
Creator: Hardy, James C. (James Clifford)
Description: When selecting a method for testing variance equality, a researcher should select a method which is robust to distribution non-normality and dissimilarity. The method should also possess sufficient power to ascertain departures from the equal variance hypothesis. This Monte Carlo study examined the robustness and power of five tests of variance equality under specific conditions. The tests examined included one procedure proposed by O'Brien (1978), two by O'Brien (1979), and two by Conover, Johnson, and Johnson (1981). Specific conditions included assorted combinations of the following factors: k=2 and k=3 groups, normal and non-normal distributional forms, similar and dissimilar distributional forms, and equal and unequal sample sizes. Under the k=2 group condition, a total of 180 combinations were examined. A total of 54 combinations were examined under the k=3 group condition. The Type I error rates and statistical power estimates were based upon 1000 replications in each combination examined. Results of this study suggest that when sample sizes are relatively large, all five procedures are robust to distribution non-normality and dissimilarity, as well as being sufficiently powerful.
