The present study was designed to assess both the construct of psychopathy in a female jail sample as well as the quality of the measures that have been employed to assess this personality style. Utilizing the multitrait-multimethod matrix proposed by Campbell and Fiske (1959), the construct of psychopathy was measured via three instruments: (a) the Antisocial Scale of the Personality Assessment Inventory, (b) the Psychopathy Checklist - Revised, and (c) the Antisocial Scale of the Personality Disorder Examination. In addition, the predictive validity of each of these measures of psychopathy was evaluated to determine their ability to predict institutional violence and non-compliance. The results revealed significant convergence and divergence across the three instruments supporting the construct of psychopathy in a female jail sample. In addition, the measures of psychopathy demonstrated moderate predictive validity.

This thesis examines the quantum dynamics of electrons in periodic semiconductor superlattices in the presence of electric fields, especially uniform static fields. Chapter 1 is an introduction to this vast and active field of research, with an analysis and suggested solutions to the fundamental theoretical difficulties. Chapter 2 is a detailed historical review of relevant theories, and Chapter 3 is a historical review of experiments. Chapter 4 is devoted to the time-independent quantum mechanical study of the electric-field-induced changes in the transmission properties of ballistic electrons, using the transfer matrix method. In Chapter 5, a new time-dependent quantum mechanical model free from the fundamental theoretical difficulties is introduced, with its validity tested at various limiting cases. A simplified method for calculating field-free bands of various potential models is designed. In Chapter 6, the general features of "Shifting Periodicity", a distinctive feature of this new model, is discussed, and a "Bloch-Floquet Theorem" is rigorously proven. Numerical evidences for the existence of Wannier-Stark-Ladders are presented, and the conditions for its experimental observability is also discussed. In Chapter 7, an analytical solution is found for Bloch Oscillations and Wannier-Stark-Ladders at low electric fields. In Chapter 8, a new quantum mechanical interpretation for Bloch …

I interviewed twenty-four International students from the following countries: Mexico, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Peru, Colombia, Brazil, Puerto Rico and Spain. Hereafter I shall refer to the respondents as Hispanic International students. My primary interest was to learn the way in which Hispanic International students defined themselves in view of ethnic definitions imposed on them by the administrative system in the U.S. First, Hispanic International students defined themselves primarily by their nationality. The second finding dealt with the usage of language. The Hispanic International students spoke Spanish with relatives and friends. They spoke English when a non-Spanish speaker joined the conversation. The third finding was related to the problems and adaptations encountered by Hispanic International students.

This study investigated the effects of personality characteristics on emergent leadership in small group settings. Two instruments were used to assess personality factors: The BASIS-A and the California Personality Inventory (CPI). A sociometric tool was developed to elicit leader ranking of female group members. The BASIS-A, was used to test for Taking Charge and Wanting Recognition lifestyles in women who emerged as leaders. The CPI was used to assess female emergent leaders for Dominance and Leadership Potential. The two instruments and a sociometric form were distributed to 115 female graduate counselor-in-training students the last week of their group counseling experience. This survey resulted in 55 respondents (N=55) from eleven discussion groups. It was expected that women who had the highest averaged leader rank would demonstrate higher test scores in Dominance, Leadership Potential, Taking Charge, and Wanting Recognition than women who received a lower averaged leader rank. It was also thought that these four test factors would be highly related. If so, a case would be made to use the BASIS-A as an emergent leader assessment tool because it is consistently based in one psychological theory. No significant effect was found between the highest leader rank and three of the test …

The effects of short term exposure (5 minutes) to EEFs at relatively high dosages (10, 25, 39, kV/m) on the electrical activity in rat pineal glands was studied. Daytime and nighttime recordings were taken from an implanted microelectrode in the gland. The data show that (1) both the activity and frequency were enhanced when the animals were exposed to EEFs at 39 kV/m continuously and discontinuously; (2) the later condition yielded a sustained increase (36%) whereas the former a brief (10 sec) increase. This enhancement was statistically significant under both conditions (day and night). The effects observed were thought to be due to membrane alterations either in the pineal gland itself or in the neural inputs to the gland.

The problem of this study was to determine the change in public support which would occur due to a public school district's going through a strategic planning process and then the implementation of specific action plans. The purpose of the study was to demonstrate that the public support necessary to assure adequate funding for the district's programs could be gained by involving the community in a broad-based planning effort and by demonstrating a concerted effort to implement the actions required by the plan.

Applied sport psychology consultation is a relatively new phenomenon with limited empirical underpinnings. The purpose of the study was to evaluate three applied sport psychology consultant personal and professional characteristics within Strong's social influence model that have been suggested to impact consultants' effectiveness in working directly with athletes and their performance problems. The three consultant characteristics were academic training, past athletic experience, and interpersonal skill. Division I female athletes (N = 187) read written preconsultation information and watched a 10- minute vignette between a consultant and an athlete. Participants completed the Counselor Rating Form-Short (CRFS), the Sport Psychology Consultant Evaluation Form (CEF), and questions concerning willingness to work with the consultant. The data from the dependent measures were analyzed by a 2 (level of consultant academic training) X 2 (level of consultant past athletic experience) X 2 (level of consultant interpersonal skill) MANOVA. Results indicated that applied sport psychology consultants' academic training and past athletic experience had only limited influence on the participants' perceptions about the consultants. The Division I female athletes unambiguously rated consultants with positive interpersonal skills more favorably on all dependent measures regardless of the consultants' level of academic training or past athletic experience. Directions for future …

Six novels of Martin Amis--The Rachel Papers, Dead Babies, Success, Money: A Suicide Note, London Fields, and The Information--are analyzed to determine to what extent they uphold moral standards traditional in Western society, particularly the categories of virtue that have descended from Aristotle and Aquinas. Thus the novels are analyzed in relation to what they show about the three theological virtues of faith, hope, and love, the cardinal virtues of prudence, temperance, courage, and justice, and the intellectual virtues of knowledge, art, skill, and understanding. Nearly all of these virtues turn out to be important in varying degrees. Faith and hope are mocked, and courage is given incidental attention. The other virtues, however, are strongly upheld, including prudence and temperance, and particularly love, justice, and the intellectual virtues. In the earlier novels, the protagonists understand love between adults egoistically, only as romance or sexual passion, with emphasis not on the welfare of the other but on getting what one wants. The need for parental love is upheld, however, with a clear understanding that its lack produces danger for the children and for society. The protagonists pity the weak, but have little understanding of love as self-sacrifice. Ego-based justice predominates as …

This study describes young writers' conferences in school districts in the state of Texas. The study proposed: (a) to describe the characteristics of young writers' conferences; (b) to determine how young writers' conferences were created and implemented; (c) to identify the purpose of writing conferences; (d) to identify the population served; (e) to describe the unique contribution of conferences; (e) to determine the perceived value of conferences to school district personnel. A 26 item survey was developed and distributed to 133 Texas school districts. One hundred percent of the districts responded to the survey or telephone interview Data was collected from the ten districts that provided young writers' conferences for young writers during the 1994-95 school year. Eighty percent of the school administrators surveyed rated their program as very beneficial for young writers. Twenty percent rated their program at the second highest rating, or beneficial. All of the districts reported that as a result of the workshop, writing has become more important in the districts. In addition, the majority of the districts reported that parents are more aware of the importance of writing and that teacher attitudes toward writing have improved as a result of participation in the workshop Districts …

The purpose of this dissertation is to develop a theory that helps explain the conditions under which firms select certain project evaluation techniques. This study uses contingency theory to analyze the impact of environmental uncertainty on the choice of project evaluation techniques. In addition to a direct measure of uncertainty, several dimensions of uncertainty are included in this study. These dimensions of uncertainty include control structure, method of financing, foreign assets, method of growth, and product domination. This study also analyzes the use of project evaluation, management science and risk management techniques in US firms over time and in UK firms over time in order to compare to prior research. A comparison of firms in the two countries are also provided. The primary method of data collection was a survey instrument. Data were also collected from annual reports and various other public sources. The variables that appear significant in the choice of project evaluation technique in US firms are environmental uncertainty, control structure, method of financing, foreign assets, and product domination. The variable that appear significant in the choice of project evaluation technique in UK firms is method of financing. US firms favor discounted cash flow techniques although this study …

The primary purpose of this study was to identify and secure perceptions of what personal and institutional factors influenced and attracted adult students to enroll in four year institutions in Oklahoma. The secondary purpose was to compare student responses by institution. The more notable findings include: (1) dominant personal factors as to why adult students in this study returned to college were reportedly to improve/advance themselves, especially as it relates to their career; (2) flexible class scheduling was reported to be the most important institutional function for recruiting adult students, with academic quality and institutional costs of education next in importance; (3) almost 90% of respondents reported being under 45 years of age; (4) almost 85% reported commuting fewer than 50 miles to class; (5) approximately 90% reported enrolling each fall and spring (6) approximately twice as many respondents who returned to college reported they did so because it was more important to them to complete an unfinished degree than to begin a degree. Conclusions drawn from this study are as follows: (1) adult students appear to be unlikely to enroll in classes meeting more than three times a week; (2) adult students in Oklahoma may no longer be described …

This study analyzes the apologies presented by Intel Corporation as a response to the Pentium™ microprocessor controversy. Dr. Andrew Grove's November 27,1994, Internet posting to the comp.sys.intel usegroup and Intel's December 20,1994, press release are analyzed using the methods of genre criticism. Further, a situational analysis is presented of the exigence and the audience. The exigence is represented by the relationship of society to technology while the audience is Internet users. This analysis attempts to demonstrate how situational factors constrain discourse related to technological flaws.

The purpose of this investigation was to describe the behavior of effective teachers working within the context of an effective school. The study focused on both the content and techniques of instruction utilized by the teachers. In addition, the research examined teacher behaviors that were external to the classroom setting, including teacher-to-teacher relationships, teacher-to-parent relationships, and teacher-to-principal relationships. A qualitative research design was selected for this study. The site was an inner city elementary campus. Data were collected from eleven K-3 teachers using participant observation and interviews over a seven-month period. Documents were also used as a source of data. The analysis of data was ongoing and cyclical based on the constant comparative method. The final analysis of data resulted in nine themes based on recurring patterns of teacher behavior. The findings suggest that a caring school culture plays an important role in a school's success and the effectiveness of its teachers. Furthermore, there does not appear to be a universal description that fits all effective teachers. Instead, effective teachers in an effective school function as autonomous decision makers in their classrooms, choosing the curriculum and techniques that work best for them and their students. They tend to focus on …

The problem of this study was to determine the difference in attitude and anxieties toward the teaching profession of beginning teachers entering public education in Texas who have been through a semester-long intern program as opposed to those who have gone through a traditional eight-week student teaching program. Purposes of the study were to provide assessment data for planning and delivering preservice training experiences to prospective teachers, to compare similarities and differences in the attitudes of prospective teachers who have been through the intern program with those who have been in traditional student teaching, and to provide useful information to colleges and universities concerning the effectiveness of their teacher education programs. The targeted study groups were 22 fall semester interns and a comparison group of 27 fall semester traditional student teachers. All participants were seeking secondary certification. The study was conducted in the fall of 1994. The groups were matched according to gender, chronological age, race designation, grade-point-average, and level of family income. In summary, the findings of this study indicate that only two of the six research questions proved to be statistically significant. It is interesting to note, however, that individually a significant percentage of both of the groups …

This dissertation provides an explanation of how André Malraux, a man of great influence on twentieth century European culture, developed his political ideology, first as an anticolonial social reformer in the 1920s, then as an antifascist militant in the 1930s. Almost all of the previous studies of Malraux have focused on his literary life, and most of them are rife with errors. This dissertation focuses on the facts of his life, rather than on a fanciful recreation from his fiction. The major sources consulted are government documents, such as police reports and dispatches, the newspapers that Malraux founded with Paul Monin, other Indochinese and Parisian newspapers, and Malraux's speeches and interviews. Other sources include the memoirs of Clara Malraux, as well as other memoirs and reminiscences from people who knew Andre Malraux during the 1920s and the 1930s. The dissertation begins with a survey of Malraux's early years, followed by a detailed account of his experiences in Indochina. Then there is a survey of the period from 1926 to 1933, when Malraux won renown as a novelist and as a man with special insight into Asian affairs. The dissertation then focuses on Malraux's career as a militant antifascist during the …

The film is about three young Korean-American adults who have adapted to American society while retaining certain aspects of Korean culture in their lives. To expose their intermingled behaviors and concepts, the film combines the observational format of a documentary with an information style employing family photos, home movie recordings, and interviews with the three subjects and their families. An accompanying production report describes the research process, pre-production, production, and post-production.

An examination of the compositional style, subject matter, and use of technology as found in Thea Musgrave's 1987 composition Narcissus for solo flute and digital delay. Includes a short history of Musgrave's formal training, an overview of her creative output, and a discussion of the evolution of her compositional style from her studies with Boulanger in Paris to the present with special emphasis on her dramatic-abstract concept and her forays into post-modernism. Provides insight into Musgrave's choice of mythological text, the literary basis of the Narcissus legend, and its impact on Western thought. Identification of principal motifs, discussion of harmonic implications, melodic language, and optional intermedia effects; and explanation of the electronic effects used within the work. Detailed analysis of the motifs, their electronic manipulations, and how they represent aurally the characters of the Narcissus myth. Listing of Musgrave's works with flute or piccolo in a primary role, details of her transcription of Narcissus for solo clarinet, and diagrams of digital delay controls and stage setting follow as appendices.

The purpose of this study was to determine the effectiveness of filial therapy in: (a) increasing Chinese parents' empathic behavior with their children; (b) increasing Chinese parents' attitude of acceptance toward their children; and (c) reducing Chinese parents' stress related to parenting. The experimental group, consisting of 18 Chinese parents, received 10 weekly 2-hour filial therapy training sessions and conducted a weekly 3 0-minute play session with one of their children. The control group, consisting of 16 Chinese parents, received no treatment during the ten weeks. All the parents were videotaped playing with their child before and after the training as a means of measuring change in empathic behavior. The two written self-report instruments completed for pretesting and posttesting purposes were the Porter Parental Acceptance Scale and the Parenting Stress Index. Analyses of Covariance revealed that the Chinese parents in the experimental group had significant changes in all 12 hypotheses, including (a) a significant increase in their level of empathic interactions with their children; (b) a significant increase in their attitude of acceptance toward their children; and (c) a significant reduction in their level of stress related to parenting. This study supports filial therapy as an effective intervention for Chinese …

This study was designed to determine if impingement and entrainment by cooling water intake at the Comanche Peak Steam Electric Station have an adverse impact upon the Squaw Creek Reservoir fish population. The yearly impingement of fish was estimated to be 262,994 of 14 species. The threadfin shad (Dorosoma petenense) accounted for 96% of this total. Entrainment of eggs and larvae for a five month period was estimated to be 15,989,987 and 42,448,794 respectively. Two fish population studies were performed on Squaw Creek Reservoir to help assess impact. It was determined that the losses due to impingement and entrainment have no adverse impact upon the fish population of Squaw Creek Reservoir.

This study investigates the impact of multimedia on the effectiveness of information scanning. Information scanning is the act of seeking and receiving a wide variety of special information to develop a thorough understanding of the organization and the environment. The application domain of this study is Executive Support Systems. The experimental task is to identify potential threats and opportunities, a strategic information-scanning activity, based on the information stored in three ESS prototypes. Forty subjects from four organizations participated in the experiment. A random assignment process allocated them into three groups. The control group used the text-based ESS. The first experimental group used the visual multimedia ESS. The second experimental group used the audiovisual multimedia ESS. The experiment was carried out on the sites of the participating organizations. The investigator measured the effectiveness of information scanning based on the number of threats and opportunities each subject identifies. A close-ended questionnaire measured subjects' retention of information. The results of this study support the cognitive-fit theory. The findings indicate that multimedia is not an appropriate presentation format for analytical tasks. Subjects who use text-based ESS identify significantly more threats and opportunities than subjects who use audiovisual multimedia ESS. The cognitive style of subjects …

Ways in which educational structures can initiate and facilitate older learners' self-directed learning projects are described in this study. The research was guided by questions related to the ways that educational organizations can facilitate the learning process for older learners. This study involved two distinct phases of research. In the first phase, a survey was administered to approximately 100 older learners at four organizations for senior citizens; the four organizations were Hillcrest Center for 55+, Golden Learning Opportunities and Workshop, Tulsa Senior Services, and Retired Senior Volunteer Program. The survey enabled the researcher to identify the 10 most frequented sites for gathering information related to the learning projects of senior citizens in Tulsa, Oklahoma. The survey respondents were volunteer participants from classes, social occasions, and other learning opportunities offered by the organizations. The survey produced three sites where older learners pursued learning activities. Phase two involved ethnographic techniques in order to identify and describe at each three sites specific educational structures that facilitated older learners' self-directed learning projects. The descriptions from each of the identified sites involved three data-collection techniques. The data-collection techniques used included interviews, observation, and artifact collection. The focus of this phase was to describe the educational …

Numerical methods are usually necessary in solving Hamiltonian systems since there is often no closed-form solution. By utilizing a general property of Hamiltonians, namely the symplectic property, all of the qualities of the system may be preserved for indefinitely long integration times because all of the integral (Poincare) invariants are conserved. This allows for more reliable results and frequently leads to significantly shorter execution times as compared to conventional methods. The resonant triad Hamiltonian with one degree of freedom will be focused upon for most of the numerical tests because of its difficult nature and, moreover, analytical results exist whereby useful comparisons can be made.

A total of 192 largemouth bass were caught at Lake Ray Roberts, Texas (1995) to investigate five controversial bass angling techniques relative to hooking mortality. The bait types were Texas-rigged scented and non-scented plastic worms, Carolina-rigged scented and non-scented plastic worms, and live golden shiners. Overall hooking mortality was 21.87% and mortality was dependent upon bait type. Highest mortality resulted from the Texas-rigged scented lures, while the lowest mortality was generated by live golden shiners. A creel survey indicated that few anglers were having success with the investigated baits. Factors that had a confirmed effect on hooking mortality were hooking location and water temperature. Hooking mortality was not excessive compared to other similar studies.
