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 …

This dissertation has compiled information about statewide bibliographic databases, their format, their cost, the number of titles and records, how they are being used, what kinds of libraries are using such databases in each state, and the effectiveness of those databases. General information about twenty-eight states' bibliographic databases is included in this dissertation. The users of thirteen states responded to a questionnaire, surveying the effectiveness of the statewide database in their state. The costs to the individual states varies from zero, where all costs are covered by local funds or Library Services and Construction Act fund, up to 4.4 million dollars. Usage of interlibrary loan increase is detailed and explained. There has never been an evaluation of the effectiveness of a statewide bibliographic database. This is a descriptive study of statewide bibliographic databases. No other such study appears in library and information sciences indexes.

A transition model (MOSAIC) is used to describe forest dynamics at the landscape scale. The model uses a semi-Markov framework by considering transition probabilities and Erlang distributed holding times in each transition. Parameters for the transition model are derived from a gap model (ZELIG). This procedure ensures conceptual consistency of the landscape model with the fine scale ecological detail represented by the forest gap model. Spatial heterogeneity in the transition model is driven by maps of terrain with characteristics contained in a Geographic Information System (GIS) database. The results of the transition model simulations, percent cover forest type maps, are exported to grid-maps in the GIS. These cover type maps can be classified and used to describe forest dynamics using landscape statistics metrics. The linkage model-GIS enhances the transition model spatial analytical capabilities. A parameterization algorithm was developed that takes as input gap model tracer files which contain the percent occupation of each cover type through time. As output, the algorithm produces a file that contains the parameter values needed for MOSAIC for each one of the possible transitions. Parameters for the holding time distribution were found by calculating an empirical estimate of the cumulative probability function and using a …

This study addresses the ways and means a conductor may approach two major twentieth century works written specifically for percussion ensemble. Performance techniques and decisions on aesthetics made by the conductor in dealing with such items as timbre, balance, pitch levels, and pitch relationships are also considered.

The purpose of this study was to examine the impact of (a) respondent age, (b) age and gender of perpetrator and victim, and (c) history of experienced violence on perceptions of elder abuse. Two-hundred and one (N = 201) middle-aged adults and 422 college students were assessed. Measures included adaptations of the Severity of Violence Against Women Scale and Elder Abuse Attitudes and Behavioral Intentions Scale-Revised. Middle-aged respondents viewed psychological behaviors more harshly than young. Middle-aged females and young males were less tolerant of middle-aged perpetrators. While past performance of elder abuse was predictive of future elder abuse, history of childhood abuse was not. Exploratory analyses examined middle-aged respondents' judgments of abusive behaviors and perceptions based on age of perpetrator. Middle-aged and young adults' willingness to respond to dimensions of quality, severity, and reportability were also examined.

The purpose of this study was to explore relationships between and among the degree of mistrust black students hold towards Whites, the students' preferences for race of counselor, and the discussion of problems that are sexual in nature. Participants consisted of 60 black females and 51 black males recruited from a university population. All subjects completed the Terrell and Terrell Cultural Mistrust Inventory, Fischer-Turner Attitudes Toward Seeking Professional Psychological Help Scale, Corrigan and Schmidt Counselor Rating Form - Short Form, Tinsley Expectations About Counseling Inventory, and the Thermometer Method Form developed specifically for this project. A multiple regression model was used to explore the hypotheses of this study. The criterion variables consisted of scores on the Expectations About Counseling Form and Counselor Rating Form. Analyses revealed that the most significant predictors of counseling expectations were race of counselor and participant gender. Black students who were asked to assume \ they would see a black counselor had more favorable expectations about counseling than those black students asked to assume they would see a white counselor. Female participants had more favorable expectations about counseling than male participants. Results also indicated that the most significant predictors of counselor ratings were race of counselor …

The purpose of this study was to examine the effects of music training on electroencephalographic (EEG) coherence of preschool children. EEG coherence is a measurement of brain wave activity that reflects anatomical and neurophysiological parameters and functional connectivity between areas of the brain. Participants were 4- to 6-year-old children divided into two groups: one received music training for 20 minutes twice a week for 10 weeks while the other group served as controls. Nineteen channels of EEG data were collected from each child pre- and post-training. Data were collected from three conditions: eyes-open resting, listening to music, and performing the Object Assembly subtest of the Weschler Preschool and Primary Scale of Intelligence - Revised (1989). The hypothesis was that the music training group would show increased EEG coherence as compared to controls. The EEG data was reduced into seven bandwidths and analyzed separately for each condition. Multiple ANCOVAs were used to factor out pre-test variability and to maximize connectivity changes between the two groups. The dependent measures were the post-QEEG electrode pairs and the covariates were the pre-QEEG electrode pairs. Results indicated the eyes-open and listening to music conditions showed more significant changes between the groups than the Object Assembly …

Free radicals, elemental and van der Waals clusters and transition state species for bimolecular chemical reactions are investigated using anion photoelectron spectroscopy. Several low-lying electronic states of ozone have been identified via photoelectron spectroscopy of O{sub 3}{sup {minus}}. A characterization of these states is important to models for atmospheric ozone reaction kinetics. The fluoroformyloxyl radical, FCO{sub 2}, has been investigated, providing vibrational frequencies and energies for two electronic states. The technique has also been employed to make the first direct observation and characterization of the NNO{sub 2} molecule. Several electronic states are observed for this species which is believed to play a role as a reactive intermediate in the N + NO{sub 2} reaction. The experimental results for all three of these radicals are supplemented by ab initio investigations of their molecular properties. The clusters investigations include studies of elemental carbon clusters (C{sub 2}{sup {minus}} {minus} C{sub 11}{sup {minus}}), and van der Waals clusters (X{sup {minus}}(CO{sub 2}){sub n}, X = I, Br, Cl; n {le} 13 and I{sup {minus}} (N{sub 2}O){sub n=1--11}). Primarily linear clusters are observed for the smaller carbon clusters, while the spectra of the larger clusters contain contribution from cyclic anion photodetachment. Very interesting ion-solvent interactions are …

The thesis advances the name of Raphael Santi, the High Renaissance artist, to be included among the famous and highly esteemed Humanists of the Renaissance period. While the artistic creativity of the Renaissance is widely recognized, the creators have traditionally been viewed as mere craftsmen. In the case of Raphael Santi, his skills as a painter have proven to be a timeless medium for the immortalizing of the elevated thinking and turbulent challenges of the time period. His interests outside of painting, including archaeology and architecture, also offer strong testimony of his Humanist background and pursuits.

This study examined a segment of the homeless population who participated in a jobs training program. The research investigated the effect of socioeconomic status, self-esteem, and locus of control on the clients in getting and keeping jobs. The training was a comprehensive 36-day treatment dealing with three major areas: (a) how to get a job, (b) how to keep a job, and (c) how to develop life-coping skills. A quasi-experimental research design was used for testing by t-tests, two-by-two repeated-measured anova, chi-square tests, and regression analysis. The findings showed that high socioeconomic status clients demonstrated higher self-esteem and internal locus of control than low socioeconomic status clients at the start of the treatment. The treatment had a significant effect on both groups with an increase in self-esteem and internal locus of control and a decrease in both external locus of control dimensions of powerful others and chance. The treatment had a greater effect on the low socioeconomic status clients than on the high socioeconomic status clients on increases in self-esteem and locus of control—internal. Both groups were successful in finding jobs, with 79% for high socioeconomic status clients and 74% for low socioeconomic status clients having jobs at the end …

Under investigation in this study was the effect of ASE certification of automotive technician training programs and other selected factors on ASE test outcome and job placement rate. This research ponders whether the time and money invested in certifying technician training programs is returning desired improvements in this automobile manufacturer's dealer service staff. The study focussed on technicians employed at Chrysler dealerships around the United States. The 2 samples totalling 387 males between the ages of 22 and 30 were drawn from 1,007 graduates of automotive technician training programs. Technicians that completed a formal training program beyond the high school level certified by the National Institute for Automotive Service Excellence (ASE) were compared to others whose training was not certified by ASE. Comparisons were made on the basis of ASE Automobile Technician Test scores and on the length of time from training program completion to employment. This research sought to identify the significance of association between three main predictors - the status of training program ASE certification, work experience and year of training program completion - and the most desirable levels of ASE test outcome (at or above 90% on the ASE test) and job placement rate (immediately following completion …

There are conflicting data in the literature regarding the effects of mirror exposure on subjective body-image evaluation. Much of the objective self-awareness research by Duval and Wicklund concluded that the presence of a mirror leads people to evaluate themselves negatively, while other studies have reported contrary findings. The primary purpose of this study was to determine the effects of mirror confrontation on individuals' body image ratings. Subjects were 88 childless, female university students. Using the Eating Disorders Inventory-Body Dissatisfaction subscale (BDS) as a screener, subjects were assigned to either a High Satisfaction group or a Low Satisfaction group. The subjects then completed the Multidimensional Body-Self Relations Questionnaire (MBSRQ) in either a Mirror or No Mirror condition. Results suggest that the presence of the mirror had no measurable effect on the subjects' ratings of themselves on the MBSRQ. There was a main effect for satisfaction level, and no interaction was found between the satisfaction level and the mirror condition. Possible explanations for these findings are offered.

The present study used the Psychoanalytic Rorschach Profile (PRP) to assess differences in personality organization in violent and nonviolent juvenile offenders.

This thesis investigates, analyzes, and discusses Picasso's imagery in the cultural context of the nineteenth-century Spanish tradition of flamenco. Two published photographs featuring the elderly artist with the gypsy guitarist Manitas de Plata initiated the study, and led me to the conclusion that selected works by Picasso were influenced psychologically, thematically, and formally by his youth which was spent in the Andalusian province of Malaga and later in Barcelona. Picasso's early artistic education occurred at precisely the same time and place as The Golden Age of Flamenco in Spain, a cultural phenomenon that profoundly affected both his life and art.

The purpose of this study was to examine the degree to which several psychological and personality variables relate to anorexic and bulimic symptomatology in female undergraduates. Past research investigating the relationship between such variables and eating disorders has been contradictory for several reasons, including lack of theoretical bases, discrepant criteria, or combination of anorexia and bulimia nervosa. Recent investigators have concluded that it is important to examine subdiagnostic levels of eating pathology, especially within a college population. Thus, the present investigation used a female undergraduate sample in determining the extent to which several psychological factors--obsessiveness, dependency, over-controlled hostility, assertiveness, perceived control, and self-esteem--account for anorexic and bulimic symptomatology. Regression analyses revealed that anorexic symptoms were best explained by obsessiveness and then two measures of dependency, emotional reliance on another and autonomy. Bulimic symptoms were related most strongly to lack of social self-confidence (a dependency measure) and obsessiveness. Clinical implications and directions for future research are addressed.

Today many selling organizations are reexamining and revising their philosophy for managing salespeople because of increase costs of hiring and maintaining a sales force. More than everm management is looking for ways to assist salespeople in becoming more productive and effective faster. One avenue for enhancing salespersons' performance is through improved sales training practices. improved sales training practices should help salespeople view training, and how sales training transcends to the job environment. Considering the need for greater understanding concerning salespeople's perceptions of sales training and assuming the influence of those perceptions on job performance and other outcomes, this study develops and executes an analysis of several proposed relationships among personal characteristics, job related characteristics, perceived training needs, sales training variables, and related outcomes. The program of research identifies and evaluates salespeople's attitudes toward sales training and specifies influences of those training perceptions on salesperson' behaviors and general attitudes. As well, a relationship between salespeople's transfer of training materials, their use, and individual performance are evaluated.

A sample of 203 grandparents, 103 of whom were surrogate parents for their grandchildren, were assessed to construct a model of their psychological functioning. Four measures of psychological functioning (i.e., well-being, satisfaction with grandparenting, meaning of grandparenthood, and perceived relationships with grandchildren) were evaluated. Path analysis of data suggested that the resumption of the parental role negatively impacted all measures except the meaning of grandparenthood. Data also suggested a sense of isolation among those raising grandchildren, as well as a sense of role confusion. These factors may have been exacerbated by behavior difficulties of many grandchildren as a result of family conflict preceding the loss of their parents, and by a lack of parenting skills of grandparents who assumed parental responsibilities. These results reinforce other work that found a preference for fulfilling voluntary, nonparental relationships with grandchildren among grandparents.

Attitudes toward mental illness and the willingness to seek psychological treatment for their children among ethnic minority group parents were investigated. Participants consisted of black, Hispanic, Native American and Asian parents. All parents were given the Terrell and Terrell Cultural Mistrust Inventory, Cohen and Struening Opinions About Mental Illness Scale, Reid-Gundlach Social Services Satisfaction Scale, Fischer-Turner Attitudes Toward Seeking Professional Help Scale, and Ahluwalia Parents' Psychological Help-Seeking Inventory. A multiple regression model was used to explore the purpose of this study. Parental mistrust level, ethnicity, education, income level, and opinions about mental illness served as predictor variables. The criterion variables consisted of scores on the Social Services Satisfaction Scale and Attitudes Toward Seeking Professional Psychological Help Scale. The results indicated that the most significant predictor of psychological help-seeking was parental cultural mistrust level. Parents with higher cultural mistrust levels were less likely to seek help. Education was also predictive of black and Native American parents' help-seeking attitude and willingness to seek psychological help for their children. Black and Native Americans with lower levels of education were less willing to seek treatment for their children than members of those ethnic groups with higher levels of education. Ethnicity was also related to …

This purpose of this research study was to identify key differences that distinguish stepfamilies from intact families with regard to individual members' perceptions of family environment and family functioning. Additionally, an initial look at how membership in a stepfamily impacts the young children's perceptions of interpersonal family functioning is offered.

The purpose of this thesis is to analyze the use of alchemy within the work of Rebecca Horn, to elucidate its presence in her work, and to illuminate its purpose as a personal philosophy and as a creative tool. The use of alchemy within Horn's work occurs as a process of revelation and transformation. Alchemy is revealed as a spiritual philosophy and as an interpretative system through the changes that occur in Horn's oeuvre. Throughout Horn's career, alchemy has developed into an interpretive system, a type of spiritual and cosmic perspective, that allows the artist to study, access, and meld diverse realities (sacred and profane) and diverse social systems (religious and scientific) into a more holistic and spiritually infused reality for herself and society-at-large. The purpose of her work is to help reinvest contemporary life with a spiritual presence by offering a model and a means of bringing the sacred into the profane.

The nucleotide sequence for the pDKl TOL plasmid region encoding toluate-1,2-dioxygenase (Xy1XYZ, TO) was determined. TO is the first enzyme in the meta-cleavage operon, responsible for the conversion of toluates and benzoates to their carboxy-substituted diols. DNA sequence analysis revealed the presence of three open reading frames (ORF). The three ORFs correspond to xylX (1353 bp), xylY (486 bp) and xylZ (1008 bp), encoding predicted protein products of 51370 Da, 19368 Da and 36256 Da, respectively.

In this study, the unique style of percussion writing in the chamber works of George Crumb, written between 1960 and 1980, is examined. The principal aspects examined within this study include: the extended instrumental techniques, the use of percussion within the musical imagery, soloistic treatment, compositional and notational procedures, and specific performance problems pertaining to the chamber work Songs, Drones, and Refrains of Death.

The present study investigated the influence of a brief, intensive biofeedback-assisted imagery training regimen on psychological, physiological and neuroendocrinological measures of pain and stress in injury related chronic pain patients. The subjects were 36 patients (myelography examcandidates) who were assigned to the imagery or wait-list control group by order of referral presentation and to formulate equivalent groups.

The charge state dependence of M-shell x-ray production cross sections of 67HO bombarded by 2-12 MeV carbon ions with and without K-vacancies are reported. The experiment was performed using an NEC 9SDH-2 tandem accelerator at the Ion Beam Modification and Analysis Laboratory of the University of North Texas. The high charge state carbon ions were produced by a post-accelerator stripping gas cell. Ultra-clean holmium targets were used in ion-atom collision to generate M-shell x rays at energies from 1.05 to 1.58 keV. The x-ray measurements were made with a windowless Si(Li) x-ray detector that was calibrated using radiative sources, particle induced x-ray emission (PIXE), and the atomic field bremsstrahlung (AFB) techniques.
