The primary purpose of this study was to determine the marketing strategies for attracting students who have nonreligious vocational goals (NRVG) that are employed by Bible colleges that are either accredited or candidates for accreditation of the American Association of Bible Colleges (AABC). Primary subpurposes were to determine the AABC's interest in marketing themselves.to NRVG; practice of educational marketing strategies toward NRVG; career planning programs and placement services available to NRVG; approaching employers with placement services for NRVG; making available seminars, placement services, and alumni networking for NRVG; and difference in marketing to NRVG according to a colleges' denomination, size, three year growth pattern, and estimated percentage of NRVG. An overview of the literature pertaining to educational marketing and marketing for a liberal arts education was given. The population chosen for this study was the accredited (87) and candidate for accreditation (15) Bible colleges of the AABC (102). Eighty (78.4%) colleges actually responded. The design of this study was survey research using a mailed questionnaire as the principal source of data collection. The statistics utilized were parametric (e.g., one-way analysis of variance and t test) and nonparametric (e.g., chi square). The results of the study indicated that AABC colleges were …

Using a case study approach, this investigation focused on the decision-making processes involved in developing budgets in two Texas school districts following a tax limitation, or rollback, election. Factors influencing the decision-making processes included the rollback election's outcome in each district, the participants, the perceptions participants held of themselves, the perceptions participants held of others in the district and community, the decisions made, and the factors influencing participants' decisions. Two Texas school districts were selected as subjects of this study which used qualitative data collection methods. In one school district, the rollback election passed. In the other, it failed. Data collection included observations of school board meetings and budget workshops. Structured interviews of school board members and administrators, pro- and antirollback proponents, and newspaper editors were conducted. Questions focused on the budgetary decision-making processes before and after the rollback elections. They also solicited information fromsubjects regarding rollback elections, the factors precipitating the rollback elections and the impact of the rollback election campaign upon each school district. Document analyses were triangulated with the observations and interviews to identify the factors influencing the budgetary decision-making process. Following the rollback elections, school officials in both districts adopted a conservative approach to budgetary decision-making. …

I have conducted detailed experimental and theoretical studies of the nonlinear optical properties of semiconductor materials useful for optical limiting. I have constructed optical limiters utilizing two-photon absorption along with photogenerated carrier defocusing as well as the bound electronic nonlinearity using the semiconducting material ZnSe. I have optimized the focusing geometry to achieve a large dynamic range while maintaining a low limiting energy for the device. The ZnSe monolithic optical limiter has achieved a limiting energy as low as 13 nJ (corresponding to 300W peak power) and a dynamic range as large as 105 at 532 nm using psec pulses. Theoretical analysis showed that the ZnSe device has a broad-band response covering the wavelength range from 550 nm to 800 nm. Moreover, I found that existing theoretical models (e.g. the Auston model and the band-resonant model using Boltzmann statistics) adequately describe the photo-generated carriers refractive nonlinearity in ZnSe. Material nonlinear optical parameters, such as the two-photon absorption coefficient β_2=5.5cm/GW, the refraction per unit carrier density σ_n=-0.8∗10^-21cm^3 and the bound electronic refraction n_2=-4∗10^-11esu, have been measured via time-integrated beam distortion experiments in the near field. A numerical code has been written to simulate the beam distortion in order to extract the …

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 …

The present longitudinal study examined the effects and interactions of several variables thought to affect adjustment to conjugal bereavement. Questionnaires were administered to 147 conjugally bereaved subjects and to 46 persons bereaved of close relatives other than spouse. Independent variables included experienced competence (self-esteem, locus of control, coping self-efficacy, and prior coping strategies), impact of loss (anticipation and preventabillty of loss, centrality of relationship and life change), and perceived resources. All of the independent variables were found to be important predictors of adjustment in conjugal bereavement. However, hypothesized interactions among variables were generally not found. Experimental variables were better predictors of adjustment in conjugal bereavement than were demographic variables. Contrary to prediction, widowed subjects tended to become more lonely and showed increased bereavement adjustment difficulties over a six month period of time. However, post hoc analysis suggested that levels of adjustment do not decline over the long term in widowhood. The present study supports a view of widowhood as a multidimensional event, characterized by seemingly contradictory feelings, experiences, and behaviors.

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 …

The main purpose of the study is to describe the developmental story of one of the larger university cooperative education programs in the United States to provide the evidence of outcomes and to utilize selected elements of the program in other colleges and universities. The study utilizes historical methodology with a descriptive approach to investigate and analyze the program's establishment, its development of staffing, organization, students, employers, funding, and its evaluation by using primary and secondary sources, annual reports, federal grant request proposals, evaluation reports, and the on-campus newspaper. The information for this study was also gathered through personal interviews with previous and present staff members of the program. The study shows that the program was established in the dean of students' office, but in order to get more support from the faculty, the program was moved to the academic affairs office. As a result of the academic support by the faculty, the program expanded. The findings show that the federal grant, Title VIII, contributed significantly to the initiation and growth of the program. The investigator observes that the director's leadership and the staff members' commitment to the program were two of the most important factors in the continued growth …

This study was a comparison of the perceptions of administrators and faculty members regarding the actual and expected role of selected components of a faculty development plan at Srinakharinwirot University-Phitsanulok, Thailand. The study also investigated whether the demographic classifications of administrators and faculty members were related to their perceptions regarding the actual and expected role of selected components of a faculty development plan. Forty-one administrators and sixty full-time faculty members completed the survey instrument. Statistical tests used to summarize and analyze the data included mean, standard deviation, t test, chi-square, and correlation ratio. The results and findings of this study showed that (a) there were no major differences between administrators and faculty members related to their perceptions of a faculty development plan; (b) faculty members perceptions of the actual and expected role of selected components of a faculty development plan were consistent to a greater degree than were the perceptions of administrators; (c) significant differences between the perceptions of administrators regarding the actual and expected role of selected components of a faculty development plan were found for only one item: study leaves; (d) there were significant differences between the perceptions of administrators and faculty members regarding the actual role of …

She broadened the depth of adult education as an advocate of knowing oneself and acting responsibly in the context of democratic responsibility.

The role for the transition team leader (TTL) has not been formalized at the state level in Texas. The purpose of this study was to determine the current perceptions of the public school superintendents in Texas for the roles, responsibilities, and functions of the TTL. The framework of the survey questionnaire was based on eight categories of expertise for the TTL derived from a review of the literature and from professional experience in preparing handicapped individuals for the world of work. The findings are listed as desirable and undesirable characteristics for the role or job description of the TTL. The desirable characteristics for the role of TTL were viewed as: (a) having experience with handicapped populations, (b) having skills to supervise others, (c) being a liaison between agencies, (d) making program adjustments as needed, (e) providing training, (f) knowing how to explain the transition program to staff, (g) being a liaison with parents, (h) being a liaison with community employers, (i) knowing pertinent regulations, (j) knowing the characteristics for each of the handicapping conditions, and (k) knowing the options and barriers to transportation for handicapped individuals in the community. The least desirable characteristics identified with the role of the TTL …

This study concerns the relationship between student evaluation of instruction and student achievement in the field of management at the community college level. Purposes of the study were to determine the subjective student evaluation of instructor performance in introductory classes of management, student achievement in the class upon completion of the course, and the relationship between the student evaluation of instructor performance and student achievement in knowledge of the course. The population studied was all 10 sections of the Principles of Management course taught by 8 instructors at Del Mar College in Corpus Christi, Texas during the fall semester of 1988. A pretest-posttest design was used to determine student achievement scores. The College Board provided sufficient copies of two versions of the College Level Examination Program (CLEP) tests for Introduction to Management for the pretest and posttest. A special statistical technique using multiple regression was used to calculate an achievement score for each student that was adjusted for entry level knowledge. Student evaluations of instructor performance were paired with the achievement scores and grades students received from the instructor. Additional confidential demographic data was obtained about the students and the instructors. Major findings of the study concluded there is no …

Recent studies suggest that synthesis of the Colony-stimulating factor (CSF) is a well regulated process. However, the molecular mechanisms of the signal transduction of the various inducers of CSF such as monokines and lymphokines are not well understood. Using Interleukin 1 (IL-1) stimulation of CSF-1 in the MIA PaCa-2 cell line as a model system, the involvement of G-protein has been studied. The IL-1 induction of CSF-1 synthesis can be inhibited by both Pertussis toxin and Cholera toxin, which are known to modify the Gᵢ and Gₛ proteins respectively, thus activating adenylate cyclase to release more cAMP. The toxin inactivation can be prevented by inhibitors of the ADP-ribosylation such as, benzamide and MBAMG. Addition of dibutyryl-cAMP inhibits the IL-1 induced CSF production. Both Theophylline and Forskolin which increase cAMP by inhibiting phosphodiesterase and stimulating adenylate cyclase respectively, also inhibit CSF-1 production. Results from these studies have shown that cAMP level inversely regulates the biosynthesis of CSF-1. Preincubation of MIA PaCa-2 cells with IL-1 and 5'- guanylylimidodiphosphate (GppNHp) prevents the inhibitory effect of pertussis toxin on CSF-1 production. These data are consistent with the hypothesis that IL-1 binds to its receptor and couples to Gᵢ∝ resulting in the inhibition of adenylate …

The problem of this study was the identification of selected characteristics of Minnie Stevens Piper Professors. Purposes of the study were: (a) to determine characteristics of Minnie Stevens Piper Professors, and (b) to determine whether these professors possess characteristics which typify outstanding college teachers as described by the Selection Research, Incorporated College Teacher Perceiver interview. Forty subjects, 20 from community colleges and 20 from senior colleges, were randomly selected from the 1978 through 1988 lists of Piper Professors. Fifteen community college and 11 senior college professors agreed to participate by being interviewed with the College Teacher Perceiver. This interview identified 13 characteristics, or themes, of excellent college teachers.

The Adolescent Discouragement Indicator (ADI) was developed to assess the Adlerian construct of discouragement. The 75-item ADI contains five subscales corresponding to the five life tasks specified in Individual Psychology and is specifically designed to pinpoint the area and degree of adolescent discouragement. Item selection was based on ratings by five prominent Adlerians and item correlation with subscale scores. Age and sex norms for the ADI were established on 225 females and 299 males 12 to 18 years of age. Findings indicate that female adolescents are less discouraged than male adolescents on all scales except the love scale and both sexes reported the least amount of discouragment on the love scale. The only significant difference among the age groups is between the 13-year-olds and the 15, 16, and 17-year-olds on the love scale. An internal consistency coefficient of .95, a 2-week test-retest coefficient of .89, and a 4-week test-retest coefficient of .92 indicates that the ADI is a reliable instrument. Negative and significant (p < .001) correlations between the ADI and Social Interest Index (Greever, Tseng, & Friedland, 1973) and between the ADI and the Social Interest Scale (Crandall, 1975) contribute to construct validity and support Adler's belief that discouragement …

The purpose of this study was to test assumptions made about characteristics of nontheatrical film and video works that were thought to contribute to the frequency with which the works were purchased. This study proposed and tested three variables for which relationships to the sales success of nontheatrical film and video works were hypothesized, as well as four variables about which no hypotheses were forwarded. Nineteen film and video distribution organizations contributed unit sales data for the period 1982-1987 on 151 works copyrighted between 1982 and 1984. These data were analyzed for relationships between sales totals and 1) curricular significance of the works' subjects, 2) relevance to general reading interest in the works' subjects, 3) intensity of competition faced by the works, 4) the works' Dewey classifications as compared to the composition of typical K-12 school library book collections, 5) the series or non-series status of the works, 6) the media format(s) in which the works were available for purchase and 7) the sources of the works' production financing. Analyses of correlation and association were performed and no significant relationships were found between sales and curricular significance of the works' subjects, or their relevance to general reading interest. Some evidence …

The purpose of this study is to investigate the perceptions of managers in Kuwait (both Kuwaiti and non- Kuwaiti) on the effects of multinational corporations (MNCs) in Kuwait and whether these effects were beneficial. The problem motivating this study is the effects that MNCs have on the social, cultural, political, legal, economic, business, and technological environments of their host countries, especially in developing nations. This study is based on a survey of the perceptions of 1,344 managers in Kuwait on the role of MNCs in changes in Kuwait. A review of the literature on MNCs and their relationships with their host countries is provided. This review focuses on four major environmental dimensions (Social-Cultural, Political-Legal, Business-Economic, and Technological) that are affected by MNCs. The factor analysis performed for this study supports this classification of the dimensions in the environment. An English questionnaire was developed from the list of major items in each of these dimensions. An Arabic version was developed using a "double-translation method." Both the English and Arabic versions of the questionnaire were pilot tested. The instrument proved to be reliable and valid. The study utilizes a 2 x 3 block design, categorizing subjects by nationality (Kuwaiti, other Arab, others) …

This study tested theoretical propositions concerning agenda-setting by minority political groups in the United States to see if they had the scope to be applicable to American Indian tribes or if there were alternative explanations for how this group places its agenda items on the formal agenda and resolves them. Indian tribes were chosen as the case study because they are of significantly different legal and political status than other minority groups upon which much of the previous research has been done. The study showed that many of the theoretical propositions regarding agenda-setting by minority groups were explanatory for agenda-setting by Indian tribes. The analyses seemed to demonstrate that Indian tribes use a closed policy subsystem to place tribal agenda items on the formal agenda. The analyses demonstrated that most tribal agenda items resolved by Congress involve no major policy changes but rather incremental changes in existing policies. The analyses also demonstrated that most federal court decisions involving Indian tribes have no broad impact or significance to all Indian tribes. The analyses showed that both Congress and the federal courts significantly influence the tribal agenda but the relationship between the courts and Congress in agenda-setting in this area of policy …

Effective utilization of instructional technology can provide a valuable method for the delivery of a school program, and enable a teacher to individualize according to student needs. Implementation of such a program is costly and requires careful planning and adequate staff development for school personnel. This study examined the degree of commitment by Texas school districts to the use of the latest technologies in their efforts to revolutionize education. Quantitative data were collected by using a survey that included five informational areas: (1) school district background, (2) funding for budget, (3) staff, (4) technology hardware, and (5) staff development. The study included 137 school districts representing the 5 University Interscholastic League (UIL) classifications (A through AAAAA). The survey was mailed to the school superintendents requesting that the persons most familiar with instructional technology be responsible for completing the questionnaires. Analysis of data examined the relationship between UIL classification and the amount of money expended on instructional technology. Correlation coefficients were determined between teachers receiving training in the use of technology and total personnel assigned to technology positions. Coefficients were calculated between a district providing a plan fortechnology and employment of a coordinator for instructional technology. Significance was established at the …

I, Blavatsky is a one-act opera based on the life of Helena Petrovna Blavatsky, a nineteenth-century Russian princess and co-founder of a religious organization called the Theosophical Society. The libretto, by the composer, involves a cast of three principal soloists and minor roles for six more singers who are also participants in a small chorus. The text format features free verse alternating with regular, rhymed strophes. Accompaniment is provided by a piano. Melodic structure combines some nineteenth-century Romantic idioms with twentieth-century style. Most of the melodic and harmonic material was intuitively composed to express the text. Rhythmic and stylistic contrasts are accomplished in the representation of the extensive travels of the main character. Stage directions involve a stylized set, several scenes requiring minimal set changes, magical effects to represent that facet of Blavatsky's life, and onstage costume changes for several characters. Approximate duration is one hour.

Eighty-seven single custodial fathers were surveyed to test the validity of previously developed typologies and/or construct a more empirically valid framework with implications for adjustment to the role. Mendes1 (1975) aggressive seekers, conciliatory seekers, conciliatory assenters, and aggressive assenters were compared to O'Brien's (1980) hostile seekers, conciliatory negotiators, and passive acceptors. In addition to demographic variables, relationship to ex-wife and child, and reasons for becoming single and obtaining custody, several personality variables were included along with measures of adjustment. One year follow-up measures of adjustment were collected to evaluate implications of typologies in adjustment. Two nearly equal groups were established in a Q type factor analysis of continuous data. Factor loadings of individual cases suggest a continuum of the two types of single fathers, rather than two distinct groups. Group differences were evaluated in a series of MANOVA and Chisquare analyses. Analysis included six factor scores from a supplemental R factor analysis of selected variables. Type I fathers are characterized as older, more passive, selfreflective, and aloof in interpersonal relationships. They are somewhat less oriented toward a relationship with their children and had felt satisfied with their wives* care of them. Alternatively, Type II fathers are younger, active, assured (not …

In the present study, an anger management treatment program was compared to a pseudo-social skills training program (self-help group) and waiting list control group to determine its effectiveness in reducing irritable/angry behavior in head injured subjects. Subjects consisted of 28 adults with previous head injury trauma who had difficulty with excessive irritability and anger. Subjects averaged 35.4 years of age and had an average of 8.9 years post head injury. Treatment consisted of 10 group sessions over a five week period. Anger management training was designed to teach subjects self management skills aimed at reducing the frequency of angry acting out behavior. Training methods included role playing, relaxation training, assertiveness training and cognitive restructuring. The pseudo-social skills training group was a self-help group designed to encourage discussion of irritability problems without teaching specific coping techniques. To assure some degree of homogeneity in cognitive abilities among subjects, minimum eligibility scores were required on five subtests of the Wechsler Adult Intelligence Scale - Revised and the Peabody Picture Vocabulary Test. Dependent measures were pre and posttreatment scores obtained from five categories of the Katz Adjustment Scale - Relative form: belligerence, negativity, general psychopathology, social obstreperousness, and social role functioning. In addition, pre …
