The purpose of this study was to examine and compare individuals that had survived a single incidence trauma, the Luby's massacre in Killeen, Texas. Participants answered questions regarding various facets of social support following the trauma, and were also screened for a diagnosis of PTSD. Participants' level of symptoms, specifically depression, anxiety, and phobic anxiety was measured over time with the SCL-90-R. The results of this study indicate that, while women initially experience a higher level of depression and phobic anxiety, there is no gender difference in rate of symptom change over time. This study also found that women were significantly higher than men on desirability, utilization and usefulness of social support. Of the target symptoms, however, only depression correlated with any facet of social support, specifically, desirability. Finally, this study questioned whether individuals would share more similarities with others based on gender or diagnosis. It is suggested by the current data that diagnosis is the better indicator of similarity.

The purpose of this study was to describe the criteria that students reported using when selecting writing samples for an assessment portfolio. Specifically, the study involved content analysis of student responses to five prompts which asked the students to give selection criteria for writing samples in language arts portfolios prepared for assessment. The population consisted of twelve eighth grade students in three urban middle schools. The students were in classes that were participating in the New Standards Portfolio Assessment Field Trial. In addition to the responses to prompts, students also submitted writing samples to be scored using New Standards rubrics. The writing samples were evaluated to determine if the students successfully selected pieces of their writing to provide evidence of standards attainment. Through the analysis of the student responses to the prompts, two categories of selection criteria were noted. Public standards were the standards that corresponded with the criteria that were presented to the students through their use of New Standards performance standards, portfolio exhibit requirements, and entry slips. Personal standards were criteria that did not correspond to the published criteria presented to the students. Ten sub-categories were identified. These ten sub-categories became the instrument for analysis and tabulation of …

This research grew from concerns relative to the mathematical performance of Spanish-speaking limited English proficient (LEP) public school students. This investigation studied the effects of the sheltered mathematics class on eighth-grade Spanish-speaking LEP students with regard to mathematical achievement, attitudes toward mathematics, the dropout rate, and the number of math credits earned in high school. The enrollment of a sheltered mathematics class was limited to LEP students. The purpose was to compare Spanish-speaking LEP students enrolled in sheltered mathematics classes with Spanish-speaking LEP students enrolled in regular mathematics classes. The research hypotheses were that achievement, mathematical attitudes, the dropout rate, and high school math credits earned would favor enrollment in sheltered mathematics classes. The data for achievement, dropout information, and mathematics course work completed were drawn from student records in the school district data bank. A mathematics attitude survey was given to a sample from the 1995-96 eighth-grade advanced level Spanish-speaking LEP students. The research hypotheses were not accepted. All of the populations did show an academic deficit. However, they did have more positive attitudes than negative attitudes toward mathematics. To improve achievement, staying in school, and a higher rate of inclusion in mathematics related careers the following recommendations were …

In the present quasi-experimental study, the relationships among individual executive characteristics, top management group processes, the business environment, and organizational performance for the gas and computer industries were investigated. Data were collected through a questionnaire using several published instruments measuring work locus of control, self-monitoring, group innovation/improvement, collaboration, and task management, environmental uncertainty, and perceptions of organizational performance. Return on assets data and sales data for several years were obtained from a business database. A total of 204 executives, 135 from the gas industry and 69 from the computer industry, returned completed questionnaires. Group processes were positively correlated with the average return on assets over three years. In addition, based on regression analyses, group processes predicted the average return on assets over three years. Work locus of control was positively correlated with group processes. However, none of the hypothesized moderator relationships were supported due to collinearity difficulties with one of the measures. Also, there were no differences between the gas and computer industries with regard to the uncertainty of the business environment.

Aspartate transcarbamoylase (ATCase) was purified from 16 selected bacterial species including existing Pseudomonas species and former species reassigned to new genera. An enormous diversity was seen among the 16 enzymes with each class of ATCase being represented. The smallest class, class C, with a catalytically active homotrimer, at 100 kDa, was found in Bacillus and other Gram positive bacteria. In this report, the ATCases from the Gram negatives, Shewanella putrefaciens and Stenotrophomonas maltophilia were added to class C membership. The enteric bacteria typify class B ATCases at 310 kDa, with a dodecameric structure composed of two catalytic trimers coupled to three regulatory dimers. A key feature of class B ATCases is the dissociability of the holoenzyme into regulatory and catalytic subunits which were enzymatically active. In this report, the ATCase from Pseudomonas indigofera was added to class B ATCases. The largest class, at 480 kDa, class A, contains the fluorescent Pseudomonas including most members of the 16S rRNA homology group I. Two polypeptides are produced from overlapping pyrBC' genes. The former, pyrB, encodes a 34 kDa catalytic polypeptide while pyrC' encodes a 45 kDa dihydroorotase-like polypeptide. Two non active trimers are made from six 34 kDa chains which are cemented …

The Hamiltonian of a stably stratified incompressible fluid in an internal water wave in a deep ocean is constructed. Studying the ocean internal wave field with its full dynamics is formidable (or unsolvable) so we consider a test-wave Hamiltonian to study the dynamical and statistical properties of the internal water wave field in a deep ocean. Chaos is present in the internal test-wave dynamics using actual coupling coefficients. Moreover, there exists a certain separatrix net that fills the phase space and is covered by a thin stochastic layer for a two-triad pure resonant interaction. The stochastic web implies the existence of diffusion of the Arnold type for the minimum dimension of a non-integrable autonomous system. For non-resonant case, stochastic layer is formed where the separatrix from KAM theory is disrupted. However, the stochasticity does not increase monotonically with increasing energy. Also, the problem of relaxation process is studied via microscopic Hamiltonian model of the test-wave interacting nonlinearly with ambient waves. Using the Mori projection technique, the projected trajectory of the test-wave is transformed to a form which corresponds to a generalized Langevin equation. The mean action of the test-wave grows ballistically for a short time regime, and quenches back to …

The problems with which this study was concerned were threefold: (a) to design a computer-based graphics presentation on the topics of functions and graphing, (b) to develop the presentation, and (c) to determine the instructional effectiveness of this computer-based graphics instruction. The computerized presentation was written in Authorware for the Macintosh computer. The population of this study consisted of three intermediate algebra classes at Collin County Community College (n = 51). A standardized examination, the Descriptive Tests of Mathematics Skills for Functions and Graphs, was used for pretest and posttest purposes. Means were calculated on these scores and compared using a t-test for correlated means. The level of significance was set at .01. The results of the data analysis indicated: 1. There was a significant difference between the pretest and posttest performance after exposure to the computer-based graphics presentation. 2. There was no significant gender difference between the pretest and posttest performance after exposure to the computer-based graphics presentation. 3. There was no significant difference between the pretest and posttest performance of the traditional and nontraditional age students after exposure to the computer-based graphics presentation. Females had a lower posttest score than the mean male posttest score, but an analysis …

Margaret Oliphant's fiction has generated some interest in recent years, but her prose essays have been ignored. Critics contend her essays are unimportant and dismiss Oliphant as a hack writer who had little sympathy with her sex. These charges are untrue, however, because many influences complicated Oliphant's writings on the Woman Question. She suffered recurring financial difficulties and gender discrimination, she lacked formal education, and most of her work was published by Blackwood's, a conservative, male-oriented periodical edited by a close personal friend. Readers who are aware of these influences find Oliphant's earliest three essays about the Woman Question especially provocative because in them Oliphant explored the dichotomy between the perceived and the real lives of women. Oliphant refined her opinions each time she wrote on the Woman Question, and a more coherent, more clearly feminist, perspective emerges in each succeeding article. In "The Laws Concerning Women," despite Oliphant's apparent position, pre-feminist markers suggest that she is tentative about feminist ideas rather than negative towards them. "The Condition of Women" offers even more prefeminist markers, Oliphant's ostensible support of the patriarchal status quo notwithstanding. In "The Great Unrepresented," an article cited by some as proof that Oliphant was against women's …

In this study, effects of facial self-reflection and complexity of self on physiological responses were investigated. Skin conductance levels were measured during baseline and neutral conditions, then under a self-focusing condition provided by mirror reflection of the face. Subjects completed measures of self-complexity, depressive affect, self-esteem, anxiety and body image satisfaction. Eye tracking data was collected during the mirror condition. Results showed a significant effect of mirror self-reflection on physiological reactivity as measured by differences between mirror and baseline mean responses. Pre-test depressive affect was correlated with low self-esteem but not with self-complexity. Self-complexity was negatively correlated with orientation to physical appearance and positively correlated with greater differences between baseline and mirror mean reactivity. Self-complexity and depressive affect did not significantly predict physiological reactivity, although a trend was found for the influence of each variable. Post-hoc analyses showed significant group differences for both self-complexity and depressive affect on physiological reactivity, although the influence of self-complexity was in the unexpected direction. Results of this study are consistent with general findings that negative self-esteem, anxiety and depression are strongly correlated. In addition, a strong correlation was found between negative self-esteem and dissociative symptoms. Exploratory analyses of eye tracking data found no significant …

This qualitative study investigated parents' awareness of and involvement in their prekindergarten child's literacy development. In addition, the feasibility of parents using a home literacy portfolio for the purpose of exchanging literacy information with teachers at a parent/teacher conference was examined. Participants included six parent/child dyads, who qualified for a Texas public school prekindergarten program by meeting the requirements for either free or reduced lunches or for the English-as-a-Second Language program. Research tools included audiotaped interviews with parents and with teachers; observations at parent/child workshop sessions, which were also videotaped; and work samples, including a home literacy portfolio from each child. Findings indicate that parents are involved in their children's literacy development. Also, at home, children participate in both open-ended literacy activities and drill-oriented literacy activities, with most of the activities falling into the open-ended category. According to the findings, all of the parents were more aware of their child's literacy achievements after attending the parent/child workshop and developing a home literacy portfolio. In addition, the home literacy portfolio proved to be a useful tool for sharing information at parent/teacher conferences. Parents and teachers exchanged literacy information at the parent/teacher conference. In the process of explaining the portfolios, the parents …

The treatment of alcoholism has had a unique historical development in the United States. This study provides a chronology of how the problem of alcoholism was defined and handled during various time periods in United States history. The process that evolved resulted in an abstinence based, comprehensive, multidisciplinary approach to the treatment of alcoholism as a primary disease based on the principles of Alcoholics Anonymous. This treatment modality, that developed outside of established medicine, is currently used by the majority of treatment providers. Seven individuals who have been actively involved in alcoholism treatment were interviewed. In addition to archival research, biographies and autobiographies were examined to gain a broad perspective. Because alcoholism is both a collective and an individual problem an effort was made to include a microsociological frame of reference within a broad sociological view. Alcoholism, or inebriety, was first perceived as a legal and moral problem. By the end of the 19th century, inebriety was recognized as an illness differing from mental illness, and separate asylums were established for its treatment. Alcoholism is currently accepted and treated as a primary disease by the majority of social institutions, but the legal and moral implications remain. National Prohibition in the …

The experimental studies of this work were done using a microwave cavity spectrometer, Escherichia coli (E-coli) bacteria, and other peripheral equipment. The experiment consists of two steps. First, a general survey of frequencies from 8 GHz to 12 GHz was made. Second, a detailed experiment for specific frequencies selected from the first survey were further studied. Interesting frequency dependent results, such as unusually higher growing or killing rates of E-coli at some frequencies, were found. It is also concluded that some results are genetic, that is, the 2nd, and 3rd subcultures showed the same growing status as the 1st cultures.

The purpose of this study was to investigate the story retelling abilities of preschool children who have experienced storybook reading and storybook reenactment bilingually, in English and Spanish, and preschool children who have experienced storybook reading and storybook reenactment in English only. This is a clinical case study employing both quantitative and qualitative measures comparing four treatment groups. Three evaluation instruments were developed by the researcher and used for posttesting; a story comprehension test, a story retelling guidesheet/scoresheet, and a storybook literacy response evaluation. In addition, participant observation and teacher interviews were used to gather qualitative data regarding learning center extensions of the target text and teacher beliefs and practices about the use of storybooks. The findings from this study show that scores for children who experienced storybook reading and storybook reenactment were significantly better on both the story retelling and story comprehension measures. In addition, a larger proportion of children who experienced storybook reading and reenactment were found to perform at the second level of literacy response on the Levels of Literacy evaluation. No differences were found in relationship to the language used on any of the dependent measures. Findings fromqualitative data showed that children were involved in limited …

The purpose of this study was to determine the pitch and intensity level characteristics found in the vibrati of preferred oboe players whose vibrato was ranked by a panel of experts. The investigation also sought to discover factors that distinguish the preferred oboe vibrato from vibrato that is less preferred.

Accurate, early diagnosis of Alzheimer's Disease is becoming increasingly important in light of its growing prevalence among the expanding older-aged adult population. Due to its ability to assess multiple domains of cognitive functioning and provide a profile of impairment rather than a simple global score, the Neurobehavioral Cognitive Status Examination (NCSE) is suggested to better assess such patterns of cognitive deficit for the purpose of diagnosis. The performance of the NCSE was compared with that of the Mini-Mental State Examination (MMSE) for diagnostic sensitivity in a sample of patients diagnosed as having probable Alzheimer's Disease. The strength of correlation between severity of cognitive impairment on these tests and report of behavior problems on the Memory and Behavior Problems Checklist (MBPC) was also explored, as was performance on the NCSE and report of behavior problems using the MBPC in predicting Single Photon Emission Computed Tomography (SPECT) scan results. The NCSE was found to exhibit greater sensitivity to physician diagnosis of probable Alzheimer's Disease relative to two versions (Serial 7's or WORLD) of the MMSE (.90, .77 and .68, respectively). While both measures were found to correlate significantly with the report of behavior problems, only a moderate proportion (NCSE = .22 and …

One of the most useful and best known goodness of fit test is the Kolmogorov one-sample test. The assumptions for the Kolmogorov (one-sample test) test are: 1. A random sample; 2. A continuous random variable; 3. F(x) is a completely specified hypothesized cumulative distribution function. The Kolmogorov one-sample test has a wide range of applications. Knowing the effect fromusing the test when an assumption is not met is of practical importance. The purpose of this research is to analyze the robustness of the Kolmogorov one-sample test to sampling from a finite discrete distribution. The standard tables for the Kolmogorov test are derived based on sampling from a theoretical continuous distribution. As such, the theoretical distribution is infinite. The standard tables do not include a method or adjustment factor to estimate the effect on table values for statistical experiments where the sample stems from a finite discrete distribution without replacement. This research provides an extension of the Kolmogorov test when the hypothesized distribution function is finite and discrete, and the sampling distribution is based on sampling without replacement. An investigative study has been conducted to explore possible tendencies and relationships in the distribution of Dn when sampling with and without replacement …

The purpose of this study was to explore heterosexual bias in the diagnosis and treatment of gay males. Two hundred-fifty (134 males and 116 females) mental health professionals from the Division of Psychotherapy (29) of the American Psychological Association participated in the study. Participants were randomly assigned to one of two case history conditions, which presented a 35-year-old male seeking therapy. Both conditions were equivalent with regards to the presenting problem (i.e., diagnostic symptoms) with the exception of his significant other (i.e., gay vs. non-gay condition). Potential bias was measured through a diagnostic rating Likert scale and a treatment plan questionnaire. Other independent variables that could potentially have an effect on diagnostic ratings were explored, such as gender, year of graduation, and theoretical orientation of the respondents. Results of the statistical analyses failed to confirm evidence of heterosexual bias. Implications for further research and training are discussed.

The purpose of this study was to investigate the effects of self-management strategies as a means of reducing off-task and disruptive behaviors of elementary school children identified as emotionally disturbed or behavior disordered (E/BD). This study provided a practical approach for classroom teachers to implement self-management strategies in classes that include children identified as having E/BD. Five elementary school children who were formally evaluated and enrolled in a special education classroom for students with E/BD were selected to participate in the study. The study also examined the effects of the self-management procedures when targeted behaviors were monitored by peers. Four resource students from the regular education class served as peer monitors. An ABAB reversal design was used to assess the effectiveness of the self-management strategy in the special education classroom. A behavior rating scale was used at the beginning of the study to develop a baseline of student behavior and during the final phase of the intervention to measure progress. The data indicated that the self-management strategies decreased the levels off-task and disruptive behaviors for all participating students. The findings of this study substantiates previous research that suggests self-management techniques help student to manage their own behaviors.

This study examined the relationship between perceptions of intellectual functioning and measures of cognitive abilities, personality variables and sociodemographic information. One hundred and fifty-two older community residing adults were asked to define their perception of intelligence by completing a questionnaire that asked the extent to which a variety of tasks are: functionally important, contribute to feelings of intellectual vitality and are the object of worry or concern. They also estimated their skill at performing each task. The hypothesis that cognitive abilities would best predict perceptions of cognitive functioning was moderately supported. Personality variables, specifically anxiety, were more predictive of the meaning variables than abilities.

Within the last decade, continuous quality improvement (CQI) has been embraced by higher education management. An important component of the quality philosophy is to institute training for everyone: faculty, administrators, staff and students—in order to achieve a cultural transformation. The purpose of this study was to identify and describe the implementation characteristics of CQI training programs and to determine whether or not and to what degree relationships exist between these characteristics and training program effectiveness, as perceived by selected individuals at two- and four-year colleges in the United States. A survey instrument was designed to elicit the perceptions of both the chief administrators and those quality professionals who are charged with the training process as they relate to specific implementation characteristics such as training content needed to convey the appropriate philosophy, program implementation processes, and the perceived effectiveness of the respondents' quality training program. A 21-item questionnaire was used to gather the data from a sample of 524 individuals at two- and four-year colleges in the United States. The dependent variables in the study related to items addressing program effectiveness based on four types of program evaluation, and the independent variables related to specific implementation characteristics. Spearman correlation matrices were …

In this study, a comparison was made between the various levels of group cognitive complexity and its relationship to task performance and task satisfaction. The goal of this research is to answer the general question, "Should decision-making groups consist of individuals who are similar in the way they differentiate and/or integrate various stimuli in order to increase performance and satisfaction?" The preceding research problem was analyzed in a laboratory setting using a 2 X 2 factorial design blocked on the variable, cognitive complexity. The Repertory Grid was used to measure the cognitive complexity of 228 student subjects. These subjects were stratified into groups of three based on their cognitive complexity score on the Repertory Grid (Kelly, 1955). Each group was treated randomly with one of two levels of task complexity (complex or not complex). Moreover, the groups received an imposedgroup structure that incorporated centralized or decentralized decision-making. Results indicated that groups consisting of cognitively complex members outperformed groups consisting of noncomplex members. No support was obtained for the two-way interaction between group cognitive complexity and either task complexity or group structure. Support was obtained for the interaction between task complexity and group structure on both task satisfaction measures. The highest …

Proponents of special education early childhood interventions programs have promoted the assumptions that these programs: (a) will have a positive effect on the long-term outcomes of preschool children with disabilities; (b) will result in some children no longer requiring special education services throughout their elementary school years; and (c) will facilitate the need for fewer services for those students who do remain in special education programs throughout their education. The purpose of this follow-up study is to identify and describe the placement decisions and the changes of exceptionality classification for children identified as special education early childhood students over the course of six follow-up years. This study (a) identifies 108 children from rural and urban school settings who were enrolled in Early Childhood Special Education (ECSE) programs in 1990-91, (b) documents their categorical label and educational placement six years later, and (c) then determines the differences in the number of hours rural and urban students receive special education and/or related services in 1996-97.

Written in the tradition of the classic spy novels of Ian Fleming and the detective novels of Raymond Chandler, The Agolmirth Conspiracy represents the return to the thriller of its traditional elements of romanticism, humanism, fast-moving action, and taut suspense, and a move away from its cynicism and dehumanization as currently practiced by authors such as John Le Carre' and Tom Clancy. Stanford Torrance, an ex-cop raised on "old-fashioned" notions of uncompromising good and naked evil and largely ignorant of computer systems and high-tech ordinance, finds himself lost in a "modern" world of shadowy operatives, hidden agendas, and numerous double-crosses. He is nevertheless able to triumph over that world when he puts his own honor, his own dignity, and his very life on the line, proving to himself and to his adversaries that such things can still make things easier to see amid today's swirling moral fog.

The just-in-time purchasing literature resoundingly endorses long-term, cooperative buyer-supplier relationships. Significant anecdotal and descriptive evidence indicates that such relationships are rare in practice, raising questions as to the performance consequences of this gulf between theory and practice. Using an accepted theoretical model of the buyer-supplier relationship, transaction cost economics, this study examined the purchasing performance implications of the nature of the buyer-supplier relationship under just-in-time exchange. The focal purpose of the study was to examine the performance consequences of crafting long-term, cooperative relationships. The research design employed was a cross-sectional field study, involving a static-group comparison, implemented through the use of a mail survey. A dual-stage cluster sample of eight hundred purchasing managers and professionals employed in the two digit Standard Industrial Classification (SIC) Code 36, Electronic and Other Electrical Equipment and Components, was provided by the National Association of Purchasing Management (NAPM). The questionnaire was pretested and the substantive validity of the measurement scales assessed. Scales were purified via correlational and reliability analyses. Criterion-related and construct validity were established via correlational, exploratory factor, and confirmatory factor analyses. The three hypotheses of the study, involving extant tests of the association between the nature of the buyer-supplier relationship and purchasing performance …
