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

In this study, computer human interaction factors are examined as a possible source of information to aid in the operation and management of local area computer networks. Users' perceptions of computer performance and response time are evaluated in relation to specific modifications in the information organization of a file server in a local area network configuration running in Novell 3.11.

A prototype Compton scatter camera for imaging gamma rays has been built and tested. This camera addresses unique aspects of gamma-ray imaging at nuclear industrial sites, including gamma-ray energies in the 0.5 to 3.0 MeV range and polychromatic fields. Analytic models of camera efficiency, resolution and contaminating events are developed. The response of the camera bears strong similarity to emission computed tomography devices used in nuclear medicine. A direct Fourier based algorithm is developed to reconstruct two-dimensional images of measured gamma-ray fields. Iterative ART and MLE algorithms are also investigated. The point response of the camera to gamma rays of energies from 0.5 to 2.8 MeV is measured and compared to the analytic models. The direct reconstruction algorithm is at least ten times more efficient than the iterative algorithms are also investigated. The point response of the camera to gamma rays energies from 0.5 to 2.8 MeV is measured and compared to the analytic models. The direct reconstruction algorithm is at least ten times more efficient than the iterative algorithms and produces images that are, in general, of the same quality. Measured images of several phantoms are shown. Important results include angular resolutions as low as 4.4{degrees}, reproduction of phantom …

This qualitative study examined the characteristics of the mother-child relationship of adult survivors of childhood sexual abuse at the time of the abuse. The study consisted of data from the McMaster Family Assessment Device (FAD), the Family of Origin Scale (FOS), and a set of structured interview questions designed by the researcher. Autonomy/intimacy concepts from the FOS examined constructs of clarity of expression, responsibility, respect, openness, acceptance of loss and separation, expression of a wide range of feelings, conflict resolution, mood and tone, and empathy.

The purpose of this study was to determine if task type, task complexity, and search mechanism would have a significant affect on task performance. The problem motivating this study is the potential for systems online help designers to construct systems that can improve the performance of computer users when they need help.

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

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

A number of protein kinases have been shown to undergo autophosphorylation, but few have demonstrated a coordinate increase or decrease in enzymatic activity as a result. Described here is a novel S6 kinase isolated from human placenta which autoactivates through autophosphorylation in vitro. This S6/H4 kinase, purified in an inactive state, was shown to be a protein of Mr of 60,000 as estimated by SDS-PAGE and could catalyze the phosphorylation of the synthetic peptide S6-21, the histone H4, and myelin basic protein. Mild digestion of the inactive S6/H4 kinase with trypsin was necessary, but not sufficient, to activate the kinase fully

This empirical study is aimed at understanding the patterns of relationships among the organization structure of self-managed work teams in terms of three sets of constructs: 1. organization-based self-esteem; 2. consequent behaviors of intrinsic work motivation, general job satisfaction, organization citizenship, and organization commitment; and 3. performance. The primary significance of this study is that it adds to the pool of empirical knowledge in the field of self-managed work team research. The significance of this study to practicing managers is that it can help them make better-informed decisions on the use of the self-managed work team structure. This study was a sample survey composed of five standardized questionnaires using a five-point Likert-type scale, open-ended questions, and demographic questions. Unstructured interviews supplemented the structured survey and for means of triangulation of results. The variables were analyzed using regression analysis for the purpose of path analysis. The site was a manufacturing plant structured around self-managed work teams. The population was full-time, first-line production employees.

Information systems research tends to ignore individual differences in users. This laboratory experiment sought to illuminate contributions of decision-makers' cognitive processes to decision outcome as reflected in four hypothesis sets: the impact of imagery preference and presentation format upon (HI) recall accuracy and upon hemispheric activation during (H2) encoding and (H3) recall, and (H4) to examine the relationship between hemispheric activation differences and accuracy differences. Point-value (specific values) and intraset-pattern (relationships between values) recall were considered. Thirty MBA students, grouped by imagery preference (cognitive style) as favoring verbal (textual) or visual (graphical) information presentation, performed computer-based recall tasks using tabular and graphical formats in a repeated measures design. Hemispheric activation (cognitive process) was assessed using ratios of EEG activity in six frequency bands captured from six pairs of homologous electrode sites during encoding and recall.

This study examines the relationship between sonnet form and musical form in Benjamin Britten's sonnet cycles with a view toward identifying the musico-poetic form how the musical form interprets the poetry. Several issues come to the fore: 1) articulation of the large-scale divisions of the poetic form in the music; 2) potential of the musical setting to make connections between lines of the text ; 3) potential of the musical setting to follow or imitate the thought processes of the poem; and 4) placement of the departure and return.

This study examined international education programs in Texas 4-year colleges and universities to determine how they compare to models found in the literature. A second purpose of the study was to compare Texas 4-year colleges and universities with out-of state benchmark institutions with a history of international education programs for over a decade. Areas examined in the study were: (a) administration of international education; (b) instructional activities of international education; (c) international student support services; and (d) outreach both in the community and abroad.

The purpose of this study was to investigate the ability of trained musicians and musically untrained college students to discriminate music instrument timbre as a function of duration. Specific factors investigated were the thresholds for timbre discrimination as a function of duration, musical ensemble participation as training, and the relative discrimination abilities of vocalists and instrumentalists. Under the conditions of this study, it can be concluded that the threshold for timbre discrimination as a function of duration is at or below 20 ms. Even though trained musicians tended to discriminate timbre better than musically untrained college students, musicians cannot discriminate timbre significantly better then those subjects who have not participated in musical ensembles. Additionally, instrumentalists tended to discriminate timbre better than vocalists, but the discrimination is not significantly different. Recommendations for further research include suggestions for a timbre discrimination measurement tool that takes into consideration the multidimensionality of timbre and the relationship of timbre discrimination to timbre source, duration, pitch, and loudness.

The purpose of this study was to investigate the effects of Project SAIL, a program designed to increase student achievement through interdisciplinary learning, upon the achievement, attendance, and attitude toward school of the ninth grade students who participated in it. The study also identified its benefits and liabilities from the perspective of teachers and students.

This research study was designed to investigate whether authentic assessment in written language is a valid assessment tool for students with and without learning disabilities. Teacher judgements were used to evaluate students' authentic writing assessments gathered from the classroom. Students' report card grades, authentic writing assessments, and two standardized writing assessments, the Test of Written Language- Revised and Written Language Assessment, were correlated to provide evidence of the validity of authentic assessment practices in written language.

The problem of this study was to develop a model for the administration of auxiliary enterprises in Texas higher education as a cooperative effort of administrators and input from other sources. The purposes were to determine which administrators currently have the responsibility for the management of auxiliary services, to evaluate the correlation between the type of administrator and the concern for fiscal and student needs, to identify problems and opportunities for useful administration, and to develop a model integrating the strengths of each administrator and the implementation of new ideas to improve auxiliary enterprise management. A survey instrument consisting of three types of questions was mailed to both Vice Presidents of Fiscal Affairs and Student Affairs at all 26 four-year public institutions in Texas. Part I questions were informational, designed to determine who administers auxiliary services. Part II consisted of 20 questions on a Likert scale to obtain both opinions on the theories of the research, and specialized knowledge of the administrators. Part III was free response to solicit ideas from the administrators for the construction of the model. Paired t-tests were performed to determine knowledge strengths of the administrators. All other information was presented in frequency tables or narrative …

The purpose of this study is to examine historically the presidential administration of John Christopher Stevens at Abilene Christian University from 1969 to 1981. During this time the institution grew in enrollment, faculty, facilities, endowment, and quality of educational opportunity. Limited to selected experiences and accomplishments, this dissertation examines Stevens' personal and administrative characteristics through interviews with him and those who worked with him. Materials were also used from Stevens' Presidential Archives in the Callie Faye Milliken Special Collections of the Herman and Margaret Brown Library at Abilene Christian University.

A body of works titled 'capriccio' have existed for over four hundred years. Most of these works are characterized by a composers abandonment of expected stylistic norms. Guided only by the fanciful whim of the composer, a capriccio exhibits extreme contrasts in the various parameters of a musical composition including melody, harmony, counterpoint, mood and texture. The composition embedded in these compositional parameters as its point of departure and development.

Low oxygen tolerances of ten fishes were estimated using an original nitrogen cascade design, and reciprocally transformed to express responses as ventilated volume necessary to satisfy minimal oxygen demand (L·mg O2^-1). Values ranged from 0.52 to 5.64 L·mg^-1 and were partitioned into three statistically distinct groups. Eight stream fishes showed moderately high tolerances reflecting metabolic adaptations associated with stream intermittency. Juvenile longear sunfish and two mollies comprised the second group. High tolerance of hypoxia may allow juvenile sunfish to avoid predation, and mollies to survive harsh environmental oxygen regimens. The sheepshead minnow was the most tolerant species of low oxygen, of those examined, explaining its presence in severely hypoxic environments.

The purposes of this study are (1) to identify the major policy issues being addressed by state agencies responsible for coordinating and regulating higher education; (2) to develop a classification system through inductive "clustering" that will aid in the analysis and synthesis of the major policy issues facing state coordinating boards for higher education; (3) to classify these policy issues; (4) to compare the goals and strategies of the various states; (5) to propose a list of significant policy issues that institutions and state agencies of higher education may face through the 1990s and into the 21st century.

The frequency dependence and temperature dependence of the complex dielectric constant of water is of great interest. The temperature dependence of the physical properties of water given in the literature, specific heat, thermal conductivity, electric conductivity, pH, etc. are compared to the a. c. (microwave) and d. c. conductivity of water with a variety of concentration of different substances such as HC1, NaCl, HaS04, etc. When each of these properties is plotted versus inverse absolute temperature, it can be seen that each sample shows "transition temperatures". In this work, Slater's perturbation equations for a resonant microwave cavity were used to analyze the experimental results for the microwave data.

This study examined the influences of a variety of verbal and non-verbal strategies on the language acquisition of six fourth grade ESL students in a discipline-based art education classroom. The art teacher/researcher spoke only English, and the students spoke Spanish almost exclusively. The art instruction occurred during eighteen 30 minute sessions, over a period of five months. The program involved the whole language approach, collaborative/cooperative learning, and the study of art concepts through verbal and graphic symbol cue cards and images of art works. Data were amassed from transcripts of video recordings, student and teacher interviews, and reflective notes. This study showed highly successful results with student growth in language acquisition and comprehension of art concepts.

In my dissertation I assert that Wilbur's poetry is not so much an attempt to balance spiritual and physical realities as an attempt to mine the richness that exists in the boundary between the two worlds. I also examine and comment on his poetry that exists in the space created by other apocalyptic interstices as well.

An activity for principal improvement that has not received much attention is the structured management effectiveness profile. The concept is to provide the principal and a group of teachers at that campus with an opportunity for assessment of the principal's management and leadership skills. A comparison between the two provides the principal with information on their perceived management strengths and weaknesses. One such profile, available through the American Association of School Administrators is the Educational Administrator Effectiveness Profile (EAEP). The EAEP was originally given to 66 principals in Tarrant County, Texas. This study reports the results of reassessment of 40 of those principals after a five year period.
