Psychopathic criminals commit more crimes, are more prone to recidivism, and more likely to engage in violent crimes and other aggressive behavior than nonpsychopathic criminals. Less is known about forensic patients, both with and without psychopathy, and their aggression. In the current study, patients in a maximum security hospital were examined with respect to their psychopathy and its predictive value on institutional management and dangerousness. In this regard, the Psychopathy Checklist (PCL) and the Psychopathy Checklist - Revised (PCL-R) have proven to be valid and reliable measures of psychopathy. The present study was an attempt to establish predictive validity for a new version: the Psychopathy Checklist Screening Version (PCLSV). As such, this study examined the PCL-SV's relationship to (a) diagnoses of Antisocial Personality Disorder according to DSM-III-R criteria and (b) the Personality Assessment Inventory (PAI) Aggression, Drug Problems, and Antisocial Features scales. The influence of major Axis I disorders on the assessment of psychopathy with the PCLSV was also examined. Participants were 150 male forensic psychiatric patients at Vernon State Hospital who were committed for various reasons: incompetence to stand trial, initial evaluation and treatment after having been found not guilty by reason of insanity, and manifest dangerousness.

Alfred Lord Tennyson's The Princess: A Medley has posed interpretative difficulties for readers since its 1847 debut. Critics, editors, and artists contemporary with Tennyson as well as in this century have puzzled over the poem's stance on the issue of the so-called Woman Question. Treating Tennyson as the first reader of the poem yields an understanding of the title character, Princess Ida, as an ambassador of Tennyson's optimistic and evolutionary views of human development and links his work to that of visionary educators of nineteenth-century England. Later artists, however, produced adaptations of the poem that twisted its hopefulness into satirical commentary, reduced its complexities to ease the task of reading, and put it to work in various causes, many ranged against the improvement of women's condition. In particular, a series of editions carried The Princess into various nations, classrooms, and homes, promoting interpretations that often obscure Tennyson's cautious optimism.

The need for a high-quality workforce to meet increased competition in the world economy has increased the need for competent vocational administrators in public 2-year postsecondary institutions. Researchers have agreed that vocational education is in a state of metamorphosis and must change to meet its challenges in the coming century. At the same time, more women are seeking and obtaining vocational administrative positions. Several studies have been done to identify the competencies needed by vocational administrators to perform their duties, but there has been little research on the actual ability to perform the administrative tasks identified by these studies. Two main purposes of this study are: (a) to determine the perceived level of administrative competencies possessed by women administrators in vocational education at the community college level in Texas; (b) to determine the adequacy of the preservice training received by these administrators to perform their administrative functions. Of the 175 women administrators randomly selected to participate in the study, 71% completed the Administrator Task Inventory. In addition to the descriptive statistics, two multiple regression analyses were tested. First, principal component analysis was used to reduce the number of dependent variables from 11 to 2, after which two multiple regression analyses …

Researchers suggest that value congruence in superior-subordinate dyads results in positive outcomes for an organization (Kemelgor, 1980; Meglino, Ravlin, & Adkins, 1989; 1990; Parkington & Schneider, 1979; Senger, 1971; Weeks, Chonko, Kahle, 1989). Further, evidence is presented which suggests that commitment at the organizational level is achieved, in part, through value congruence at the individual level of analysis. Analysis at the individual level reflects the effect of shared values on interpersonal relations. Work value congruence in a dyad enhances the development of a high quality dyadic relationship. The subordinate in such a relationship perceives being allowed more participation in decision making, more positive work experiences, and less role stress (Turban & Jones, 1988). These items have been found to be predictor variables of commitment from Steer's (1977) framework of antecedents. In this study, a research model was proposed which suggests that work value congruence in the subordinate-superior dyad leads to organizational commitment through its effect on subordinate perceptions of role stress characteristics, participation, and work experiences. The model integrates the organizational aspects of the Steer's (1977) framework for organizational commitment with the interpersonal effect of work value congruence. A field study design using a sample of 96 subordinate-superior dyads at …

This study described and explored perceptions of the context and behaviors of seven 4-year-old children whose parents attended a parenting education program. The problem was to explore a group of 9 volunteer parents' perceptions of their parenting styles and perceptions of their 4-year-old children at home while the parents participated in, and completed, a minimum of 4 out of 6 Active Parenting Today parenting education classes. Volunteer parents were recruited during public school registration for prekindergarten. In addition, perceptions of 4 teachers and 4 classroom educational aides in regard to behaviors of the 4-year-old children whose parents participated in and completed the Active Parenting Today program were explored.

The thesis is a traditional piano quintet in the manner of Bartok, incorporating compositional techniques such as golden ratio and using folk materials. Special effects on strings are limited for easy conversion to wind instruments. The piece is about 15 minutes long.

This research investigated whether the buyer-seller interorganizational relationship (IOR) differed between a firm and two classes of customers. The first class used electronic data interchange (EDI) with the firm and the second class used the traditional paper-based purchasing system. IOR characteristics included reputation, skill, direct power, indirect power, reciprocity, and efficiency.

This was a qualitative study designed to document the historical process which brought about a performance-centered accountability (or results-based) system in educator preparation in Texas as reflected in the documents of the first 17 institutions approved under the new approval process for educator preparation. The study will also serve as a historical record which used the change process in political systems to analyze the adoption of the Accountability System for Educator Preparation (ASEP). Additionally, the study provided a thorough review of the literature on Michael Fullan's Change Process Model and David Easton's Political Systems Model.

This study extends a research stream calling for further research regarding pricing and accounting feedback. Marketing executives rely heavily on accounting information for pricing decisions, yet criticize accounting feedback usefulness. To address this criticism, this research integrates the cognitive psychology and accounting literature addressing feedback effectiveness with pricing research in the marketing discipline. The research extends the scope of previous accounting feedback studies by using a control group and comparing two proxies of subject task knowledge; years of pricing experience and a measure of the cognitive structure of pricing knowledge. In addition, this research manipulates task complexity by using two different accounting systems. These systems vary in the number of cost pools used in allocating overhead, resulting in differentially projected cost and profit information. A total of 60 subjects participated in a computer laboratory experiment. These subjects were non-accountants with varying amounts of pricing knowledge. Subjects were randomly assigned to six experimental groups which varied by feedback type (no accounting feedback, outcome feedback only, or a combination of outcome and task properties feedback) and task complexity (high or low number of overhead cost pools). The subjects attempted to (1) maximize profits for a product during 15 rounds of pricing decisions, …

This study traced the development of the Equity 2000 Program in the Fort Worth Independent School District from its inception in 1990 to its sixth and final year as an exemplary program for equal access to higher education for minority and underserved youth. Program components included mathematics, counseling, staff development, academic enrichment activities, parent education and higher education linkages. Both primary and secondary sources were evaluated from the perspectives of internal and external criticism. The following conclusions were reached: 1) District policy must change if minority students are going to access algebra and geometry. 2) The lack of involvement of other curriculum areas created primarily a mathematics inservice program. 3) Required inservice was necessary to provide improved and more effective campus and district results. 4) The precollege guidance and counseling component needed integration with the mathematics component. 5) Lack of principals' involvement in the early development of the program contributed to uneven administrative support. 6) There was no definitive strategy for parental inclusion. 7) Funding sources were inadequate to fully implement all parts of the program. 8) There was limited participation of local institutions of higher education. 9) There was a lack of an ongoing, structured evaluation process to document …

In order to explain presidential decisions to use force, a model is developed that incorporates three distinct decision-making environments. The results indicate the president is responsive not only to domestic and international environments, but also to the resource evaluation environment. The evidence here demonstrates that while these two environments are important the president can't use force arbitrarily; rather, his evaluation of resources available for the use of force can limit his ability to engage the military during crisis situations.

It has been widely believed that modernity is a byproduct of a nuclear family system, a highly urbanized society, and a secular way of life. As such, developing countries are characterized as modern insofar as their social and cultural structures are able to correspond to these criteria. To examine the validity of these propositions, data on two randomly-selected generations--daughters and mothers in the United Arab Emirates--were generated.

Recent research in juvenile justice has focussed on identifying precursors of delinquency, which are referred to as "risk factors." These are biological or psychosocial conditions that increase the probability of an individual developing problem behaviors. Delinquency prevention and intervention programs are adopting a risk-focussed approach which attempts to reduce targeted youth's exposure to risk factors. Limited attention has been paid to investigating whether commonly accepted risk factors are equally relevant across various subtypes of juvenile offenders. Two subgroups of offenders deserving of special attention by virtue of their extremely high prevalence rates in the juvenile justice system are those with emotional/behavioral disorders (EBD) and those with learning disabilities (LD). The purpose of this study was to determine the relevance of specific individually-, family-, and school-based risk factors for delinquency across three specific groups of juvenile offenders: (a) those with EBD, (b) those with LD, and (c) those who did not qualify as disabled under the definition of disability used in the Individuals with Disabilities Education Act (IDEA). Individual risk factors that were measured included aggressive/acting-out behaviors, irresponsible/inattentive behaviors, fearful/anxious behaviors, social withdrawn behaviors, age at first arrest and history of substance use. School-based risk factors examined were students' reading and …

Gas phase kinetics and thermochemistry of several halogenated species relevant to atmospheric, combustion and plasma chemistry were studied using experimental and ab initio theoretical techniques.

The primary question addressed was, "What effect does educational attainment and acquired knowledge of ageing have on negative ageism?" Subsidiary questions are, "What effect does; age, sex, and positive/negative experiences with aged individuals, have on ageism?"

This study analyzes the effect of three different high school scheduling options on the delivery of biology instruction, on student achievement, and on student perceptions of their instructional activities. Participants were biology students and teachers from twelve high schools in a north Texas urban school district of 76,000. Block classes had 11 to 18 percent less instructional time than traditional classes. Texas Biology I End-of-Course Examination achievement results for 3,195 students along with student and teacher surveys provided information on instructional activities, attitudes, and individualization. Using an analysis of variance at a j i< .01 the following results were found; student achievement was significantly different for each of the scheduled comparisons groups, test score means were not statistically significant between the scheduled comparison groups for different ethnic groups, economically disadvantaged students, and magnet students. No significant differences were found between the science learning activity index for each of the scheduled groups. Student response data when disaggregrated and reaggregrated into program groups found a statistically significant higher index of science activity at a p. < .01 for magnet students when compared to both the regular and honor students. Regular program students had a significantly higher index of individualization than honors program …

This was a quantitative study designed to determine the role orientation and role behavior of school resource officers in public secondary schools in a metropolitan area of central Texas. The perception of role orientation and role behavior was assessed by two relevant groups: secondary school principals and school resource officers. Each group's perception of role orientation and role behavior was compared to determine if role conflict was an inhibiting factor in the job performance of the recently created school resource officer position. This instrument relied heavily on the work of James Telb who conducted a 1982 study involving the role perceptions of public safety officers in public institutions of higher learning as viewed by senior patrol officers and campus judicial officers. A questionnaire was distributed to both groups to assess perceptions of role orientation of school resource officers as either service oriented or law enforcement oriented. A statistically significant difference in role orientation was identified between groups on two factors: maintenance of traditional police values and police discretionary powers and handling of behavioral scenarios.

The present study compared the academic stress levels of 450 college sophomore students at a public university and a public two-year college. This investigation also explored the levels of academic stress by institutional type, age, gender, and ethnicity. Data were obtained from having the subjects complete the Academic Stress Scale, a questionnaire which lists thirty five stress items found in the college classroom. Analysis of variance and t-tests were used to analyze the data. There were 225 subjects each in the community college group and the university group. The university group had a statistically significant higher mean stress score than the community college group. 294 traditional age (23 and younger) and 156 nontraditional age (24 and over) subjects stress levels were compared. It was found that the traditional age college student group experienced a statistically significant higher academic stress level in both academic settings. Group means were compared between the stress scores of 245 female and 205 male subjects. At both the community college and university levels, the female group had a statistically significant higher level of academic stress. The academic stress levels were also compared according to ethnicity. The minority group consisted of 104 subjects and 346 subjects comprised …

David Mamet is best known as a playwright, but he also has a thriving film career, both as screenwriter and as director. He has taken very seriously each of these roles, formulating theories that, he suggests, account for the creative choices he makes. Though Mamet sometimes contradicts himself, as when he suggests that viewers should have the satisfaction of constructing their own meaning of a work, but at the same time is devoted to montage, which works by juxtaposing images that lead to a single interpretation, he clearly sees the story as a critical avenue into the spectator's unconscious, where he hopes it will resonate with a truth that speaks directly to the individual. His films House of Games, Things Change, and Homicide clearly reflect his ideas on the best ways of conveying a story on film. In House of Games, Mamet draws on Bruno Bettelheim's theories to construct a fairy tale designed to act on adult viewers in the same way that fairy tales act on the child. In Things Change, he creates a fable that explores issues of friendship and honor within the milieu of the gangster genre. And in Homicide, Mamet uses the expectations viewers bring to …

Dental amalgams have been used for centuries as major restorative materials for decaying teeth. Amalgams are prepared by mixing alloy particles which contain Ag, Sn, and Cu as the major constituent elements with liquid Hg. The study of microstructure is essential in understanding the setting reactions and improving the properties of amalgams. Until the work reported in this dissertation, optical microscopy (OM), scanning electron microscopy (SEM), and x-ray diffractometry (XRD) were used commonly to analyze amalgam microstructures. No previous systematic transmission electron microscopy (TEM) study has been performed due to sample preparation difficulties and composite structure of dental amalgams. The goal of this research was to carry out detailed microstructural and compositional studies of dental amalgams. This was accomplished using the enhanced spatial resolution of the TEM and its associated microanalytical techniques, namely, scanning transmission electron microscopy (STEM), x-ray energy dispersive spectroscopy (XEDS) and micro-microdiffraction (μμD). A new method was developed for thinning amalgam samples to electron transparency using the "wedge technique." Velvalloy, a low-Cu amalgam, and Tytin, a high-Cu amalgam, were the two amalgams characterized. Velvalloy is composed of a Ag₂Hg₃ (γ₁)/HgSn₇₋₉ (γ₂) matrix surrounding unreacted Ag₃Sn (γ) particles. In addition, hitherto uncharacterized reaction layers between Ag₃Sn(γ)/Ag₂Hg₃ (γ₂) and …

This study was designed to assess the difference in litigation between two courts: one mandating For Kids' Sake, a psycho-educational seminar for divorcing parents, and the other not so mandating. The level of difficulty of children's adjustment to divorce has been positively correlated with parental hostility. More hostile parents would have more contested cases, interim motions, and relitigations. This research compared final dispositions, interim motions, and relitigation between parents in two courts in Collin County, Texas. The treatment group was from the 219th District Court which mandated all divorcing parents with minor children to attend the For Kids' Sake Seminar and the control group was from the 199th District Court which did not so mandate. Archival data was collected from a computer generated list for the Total group data to assess final dispositions and directly from District Clerk files for the In-Depth group data to assess interim motions and relitigation. The Total group was comprised of 679 research subjects with 330 cases in the treatment group and 349 cases in the control group. The In-Depth group consisted of 182 cases from both courts with 84 cases in the treatment group and 98 cases in the control group. Chi square analysis …

This research grows out of an interest in what scholars commonly call the wisdom tradition of the ancient near east. This tradition or movement involved groups of thinkers and writers, known collectively as scribes, who were concerned in a philosophical way with the problems of living, and with principles of living well. Such communities are known to have flourished in Egypt, the various kingdoms of Mesopotamia, and western Asia, from at least the middle of the third millennium B.C. These scribal communities are also known to have sponsored schools, intended primarily for training in statecraft and the professions, but also for training in the scribal profession per se. The documentary and historical record indicates that such schools provided education from the most rudimentary level of literacy and writing to the most advanced levels of scribal scholarship. These advanced levels of training were functionally equivalent to what is nowadays known as higher education; and the ideals, the philosophy, which guided this enterprise found expression in a corpus of literature bearing the name "wisdom." The problem for this dissertation is whether or not there was in ancient Israel, specifically in the Solomonic era (10th century, B.C.), such an advanced scribal school associated …

The aim of this study was to identify the characteristics of non-traditional female students and their perceived reasons for university studies.
