The purpose of the present study was to ascertain if environmentally sensitive patients would demonstrate different memory deficit patterns than psychiatric patients on objectively measurable memory tasks. One-hundred sixteen patients were surveyed; 56 environmentally sensitive patients were compared to 60 psychiatric patients. All subjects were administered a Wechsler Adult Intelligence Scale-Revised screen, the Wechsler Memory Scale-Revised and the Harrell-Butler Comprehensive Neurocognitive Screen after history of head injury was ruled out. Results indicate a significantly different pattern of memory dysfunction between the environmental patients and the psychiatric patients, indicating two different etiologies. A screening device derived from the coefficients from a Canonical Analysis is proposed to distinguish between the two populations in the absence of blood serum levels of environmental toxins or poisons. The detrimental effects of misdiagnosis and the beneficial effects of accurate diagnosis of environmental illness are discussed.

This study describes the language behaviors and social strategies of English as Second Language (ESL) and English as Primary Language (EPL) pre-kindergarten students during cooperative Computer Assisted Instruction (CAI) experiences. Thirty-three pre-kindergarten subjects ages four to five years, were videotaped at two personal computers during self-selected center time. The sources of data for this descriptive study were a parent computer survey, videotapes, a subject interview derived from the Young Children's Computer Inventory, and written records.

A continuous convex function on an open interval of the real line is differentiable everywhere except on a countable subset of its domain. There has been interest in the problem of characterizing those Banach spaces where the continuous functions exhibit similar differentiability properties. In this paper we show that if a Banach space E has property (H*) and B_E• is weak* sequentially compact, then E is an Asplund space. In the case where the space is weakly compactly generated, it is shown that property (H*) is equivalent for the space to admit an equivalent Frechet differentiable norm. Moreover, we define the SH* spaces, show that every SH* space is an Asplund space, and show that every weakly sequentially complete SH* space is reflexive. Also, we study the relation between property (H*) and the asymptotic norming property (ANP). By a slight modification of the ANP we define the ANP*, and show that if the dual of a Banach spaces has the ANP*-I then the space admits an equivalent Fréchet differentiability norm, and that the ANP*-II is equivalent to the space having property (H*) and the closed unit ball of the dual is weak* sequentially compact. Also, we show that in the …

Rolando Hinojosa's Klail Citv Death Trip Series purports to give a picture of life in the Texas Rio Grande Valley from roughly the 1930s to the present. Much of Hinojosa's attention is directed toward the tensions that characterize relations between the mexicano and Anglo cultures. Hinojosa's novel sequence in large part documents the ever-increasing acculturation and assimilation of the mexicano into Anglo society.

The simplicity and ease of use of the Rasch procedure is a decided advantage. The test user needs only two numbers: the frequency of persons who answered each item correctly and the Rasch-calibrated item difficulty, usually a part of an existing item bank. Norms can be computed quickly for any specific group of interest. In addition, once the selected items from the calibrated bank are normed, any test, built from the item bank, is automatically norm-referenced. Thus, it was concluded that the Rasch quick norm procedure is a meaningful alternative to traditional classical true score norming for test users who desire normative data.

The influence of parental marital status and parental conflict on the separation-individuation process of college students was investigated in the present study. Past studies have suggested that parental divorce and parental conflict accelerate separation. However, no studies have measured more than one dimension of separation-individuation. In this study the process of separation-individuation was operationalized as involving three dimensions: psychological separation from parents (Psychological Separation Inventory); emotional attachments to parents and peers (Inventory of Parent and Peer Attachment); and the development of an identity (Extended Objective Measure of Ego Identity Status). The sample consisted of 120 male and 120 female undergraduates between the ages of 18 and 22, one-half with parents who were married and one-half with parents who had divorced in the last five years. Subjects completed self-report measures of parental conflict, psychological separation, attachment to parents and to peers, and identity status. Predictions that parental conflict would affect students in intact families differently than their peers with divorced parents were not supported. Instead, parental divorce and conflict were found to have different effects on the components of the separation-individuation process. Subjects reporting higher parental conflict levels described more independent functioning, more negative feelings toward parents, less attachment to parents …

O-Acetylserine Sulfhydrylase (OASS) is a pyridoxal phosphate enzyme that catalyzes the reaction of O-acetyl-Lserine with sulfide to give L-cysteine. OASS is present as two isoforms, designated -A and -B. The kinetic mechanism of OASS-A is well known and there is also much known concerning the acid-base chemistry of the enzyme. However, little is known concerning the location of the rate determining steps, the sequencing of chemical steps that occur at the active site, or the nature of the rate determining transition states. The studies performed to help elucidate these aspects of the OASS-A mechanism included determination of the thermodynamics of both half reactions, along with studies utilizing substrate analogs of OAS halting the reaction at specific points along the reaction pathway allowing the identification of reaction intermediates. The free energy change of the first half reaction was shown to be -5.7 Kcal/mole while the second half reaction was shown to be, for all intents and purposes, irreversible. Intermediates along the reaction pathway that have been previously identified include the internal Schiff base and the a-aminoacrylate. The external Schiff base was identified using the analogs cysteine, alanine, and glycine while the geminal diamine was identified using the analog serine. Formation of …

During World War II the composer Kurt Weill was in America writing for the Broadway stage. On August 27, 1943, he became an American citizen and was eager to volunteer his talent to the American war effort. Among his many wartime musical contributions are fourteen songs, all with war-related texts, which can be divided into three distinct groups: the American propaganda songs (8), the German propaganda songs (2), and the Walt Whitman songs (4). It is the purpose of this paper to present a comparative analysis of a representative group of these war songs (two from each group) in order to illustrate Weill's musical versatility. The American propaganda songs were written in a purely popular song style; sung by Broadway actors; directed toward an American audience; with texts by the Broadway lyricist Oscar Hammerstein II and the Hollywood movie executive Howard Dietz. The German propaganda songs were written in a cabaret song style; sung in German by Weill's wife, Lotte Lenya; directed toward a German audience behind enemy lines; with texts by the German playwright Bertolt Brecht and the German cabaret writer Walter Mehring. The Four Walt Whitman Songs were written in a classical art song style; sung by classically …

Four aspects of the dynamics of continuous-time dynamical systems are studied in this work. The relationship between the Lyapunov exponents of the original system and the Lyapunov exponents of induced Poincare maps is examined. The behavior of these Poincare maps as discriminators of chaos from noise is explored, and the possible Poissonian statistics generated at rarely visited surfaces are studied.

A primary purpose of the study was to articulate the significance of these compositions to the twentieth century repertoire, with special attention given to Dies Natalis, recognized as an outstanding contribution to English music literature. Overviews and specific analyses, with pertinent performance applications and background data, fulfill this purpose and provide information of merit for the programming and performance of Finzi's songs for high male voice.

In this dissertation the results of Jerrum and Sinclair on the conductance of Markov chains are used to prove that almost all generalized Steinhaus graphs are rapidly mixing and an algorithm for the uniform generation of 2 - (4k + 1,4,1) cyclic Mendelsohn designs is developed.

This study concerns the leadership behavior of the deans of students in the four public universities of Kenya and their constituent colleges. Both the real and ideal versions of the Leader Behavior Description Questionnaire and the demographic questionnaire developed under the auspices of faculty advisors were used to collect data from 10 deans of students, 55 student affairs staff members, and 130 student leaders--who constituted the sample of 195 who responded from the chosen population. Data were analyzed using a series of one-way analyses of variance utilizing the f test of statistical difference. Fisher's least significant difference test, a multiple comparison procedure, was utilized to make all pairwise comparisons which were detected by the ANOVA to differ significantly from one-another among the respective mean ratings of the three groups surveyed. Twelve hypotheses were developed and tested, and the major findings included: There were significant differences among the perceptions of the deans of students, student affairs staff members, and student leaders regarding the real and ideal leadership behavior of the deans of students concerning initiating structure and consideration--the two leadership dimensions surveyed on the questionnaire.

This study was designed to determine the effectiveness of filial therapy as a method of intervention for single parents and their children.

The purposes of this study were (a) to examine whether social support decreases as the person with HIV disease progresses from asymptomatic HIV to symptomatic AIDS and (b) to examine the extent to which general well-being might be mediated through a religious and/or spiritual support system.

The primary purpose of this study was to find the content and form of movies which conform to the taste of the majority of Thai audiences and, at the same time, are universal enough to attract international audiences. Because film is an extension of other art forms, this required extensive research into the roots of Thai performing arts.

The purpose of this study was to ascertain the image of the University of North Texas as perceived by the University Administration and Board of Regents, Texas Higher Education Coordinating Baord and selected Legislators, and the Boards of Directors of the Metroplex area Chambers of Commerce. The significance of the study was to contribute knowledge that could be used to construct a more direct and cost effective marketing plan.

The purpose of this study was to determine the accuracy of advertised reports by computer software companies claiming to improve critical thinking skills.

The purpose of this study was to analyze and compare the values, beliefs, and ideas in school reading textbooks (Readers) in Taiwan and in Texas. It intended to examine the social control function of school Readers, with which a culture deliberately molds its young generation. This study employed primarily qualitative methods. The collection of data used the technique of content analysis, student surveys, and teacher expert panel discussions. The analysis of data followed a constant comparative approach. The themes shared by the two sets of Readers included family, friends, humans and living creatures, political ideals, reading/writing, appreciation of nature, science, indomitable spirit, turning danger into safety, setting goals, education, desirable and undesirable qualities or behaviors. Despite the similarities of these themes, the substance or focus of them may vary. The themes unique to the Texas Readers were content knowledge, cultural diversity, dilemma and choice, observations about people, words, tomorrow's technology, winning, and general truth. The themes unique to the Taiwan Readers included life philosophy, learning, necessary difficulties, sensitivity, and military strategies. The theme occurring most frequently in both sets of Readers was the desirable qualities or behaviors. The values advocated in the Taiwan Readers were idealistic and had a society-centered …

This research investigated the chemistries and mechanisms involved in lead-cement systems through the study of a larger number of lead compounds.

In this study, 78 kindergarten and first-grade children were interviewed about their writing to identify indicators of self-assessment. Writing samples for each participant were saved over a three month period, then compared and discussed by the child. Results indicated that these young children did engage in self:-assessment behaviors. The classroom teachers were asked to place the participants in their classes along a writing continuum known as a Writing Band. Graphs were presented to show the writing levels of the children by classroom. In addition, each classroom was surveyed to document events which promote literacy development within the framework of an integrated curriculum. Writing samples for each child were collected and kept in a portfolio. Participants were interviewed regarding the contents of the portfolio. Children in two of the kindergarten classes were interviewed using 5 samples collected over a 2 1/2 month time period, and all other participants were interviewed using 6 writing samples collected over a 3 month period. Findings indicated that not only did these young children recognize growth in their writing, but they also assessed that growth based on outward, physical features of their writing. The writing ability of each child at the beginning of the study did …

The regulation of short chain fatty acid metabolism has been examined. Metabolism of acetoacetate, and short chain fatty acids such as butyrate and valerate, is predicated upon the expression of genes of the ato operon. Acetoacetate induces expression of a CoA transferase (encoded by the atoDA genes) and expression of a thiolase (encoded by the atoB gene). Metabolism of saturated short chain fatty acids requires the activities of the transferase and thiolase and enzymes of 6-oxidation as well. Spontaneous mutant strains were isolated that were either constitutive or that were inducible by valerate or butyrate instead of acetoacetate.

This study focuses on clarifying the relationships among decentralization, privatization, and economic development in developing countries.

The study inquires into the dynamic relationship between Protestantism and culture in The Faerie Oueene. The American Protestant theologian Reinhold Niebuhr makes penetrating analyses of the relationship between man's cultural potentials and the insights of Protestant Christianity which greatly illuminate how Spenser searches for a comprehensive religious, ethical, political, and social vision for the Christian community of Protestant England. But Spenser maintains the tension between culture and Christianity to the end, refusing to offer a merely coherent system of principles based on the doctrine of Christianity.
