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.

Free radicals, elemental and van der Waals clusters and transition state species for bimolecular chemical reactions are investigated using anion photoelectron spectroscopy. Several low-lying electronic states of ozone have been identified via photoelectron spectroscopy of O{sub 3}{sup {minus}}. A characterization of these states is important to models for atmospheric ozone reaction kinetics. The fluoroformyloxyl radical, FCO{sub 2}, has been investigated, providing vibrational frequencies and energies for two electronic states. The technique has also been employed to make the first direct observation and characterization of the NNO{sub 2} molecule. Several electronic states are observed for this species which is believed to play a role as a reactive intermediate in the N + NO{sub 2} reaction. The experimental results for all three of these radicals are supplemented by ab initio investigations of their molecular properties. The clusters investigations include studies of elemental carbon clusters (C{sub 2}{sup {minus}} {minus} C{sub 11}{sup {minus}}), and van der Waals clusters (X{sup {minus}}(CO{sub 2}){sub n}, X = I, Br, Cl; n {le} 13 and I{sup {minus}} (N{sub 2}O){sub n=1--11}). Primarily linear clusters are observed for the smaller carbon clusters, while the spectra of the larger clusters contain contribution from cyclic anion photodetachment. Very interesting ion-solvent interactions are …

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 …

Focus of the study is C acceptor doping of GaAs, since C diffusion coefficient is at least one order of magnitude lower than that of other common p-type dopants in GaAs. C ion implantation results in a concentration of free holes in the valence band < 10% of that of the implanted C atoms for doses > 10{sup 14}/cm{sup 2}. Rutherford backscattering, electrical measurements, Raman spectroscopy, and Fourier transform infrared spectroscopy were amonth the techniques used. Ga co-implantation increased the C activation in two steps: first, the additional radiation damage creates vacant As sites that the implanted C can occupy, and second, it maintains the stoichiometry of the implanted layer, reducing the number of compensating native defects. In InP, the behavior of C was different from that in GaAs. C acts as n-type dopant in the In site; however, its incorporation by implantation was difficult to control; experiments using P co-implants were inconsistent. The lattice position of inactive C in GaAs in implanted and epitaxial layers is discussed; evidence for formation of C precipitates in GaAs and InP was found. Correlation of the results with literature on C doping in III-V semiconductors led to a phenomenological description of C in …

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 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.

The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.

Certain measures of aerobic power have been shown to have a high relationship with endurance performance. Critical power (CP) has also been shown to be well correlated to endurance performance, but few studies have evaluated its use in a competitive scenario. In this study, cardiorespiratory-metabolic measures were evaluated in 13 highly trained cyclists to determine their relationship to performance in a 17 km time trial. Critical power, determined from the nonlinear power-time model, was also evaluated to determine its relationship to performance in a 17 km time trial. Results indicate that the traditional indicators of V02max and ventilatory anaerobic threshold were well correlated to TT performance (r=-0.86, r=-0.79, respectively). The principal finding from this study was that performance in a bicycle time trial is related to CP at least as well as to cardiorespirator-ymetabolic measures. In fact, the results fromthis study suggest that the relationship between performance and CP is stronger (r=-0.89). Use of the critical power concept is attractive because testing requires only a cycle ergometer and a stopwatch to estimate a parameter of aerobic fitness.

The purpose of this study was to determine whether kindergarten children possess the ability to recognize, match, and discuss lines and line qualities. Using graphics and art reproductions, three matching tasks were constructed which examined young children's awareness of the line qualities of length, width, straightness, direction, movement, and uniformity. Graphics and art reproductions were also used to construct two tracing tasks employed to examine young children's awareness of actual and implied lines. The tasks were administered to 69 kindergarten students from four elementary schools in a public school district in the north central Texas area.

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.

Red Dresses for Funerals contains a scholarly preface concerning the nature of factuality versus credibility in the writing of fiction. Four original short stories are included in this thesis. "A Night With Lawrence Welk" explores the relationship between a patient and student intern psychologist. "Red Dresses for Funerals" is about a wedding that plays a significant role in a variety of the characters' lives. "Trace Elements" is the only story involving young children. "Trace Elements" explores the beginning of understanding of some of the grimmer aspects of reality. "Expectations, Great and Otherwise" addresses the issue of denial. These stories are linked by their setting, a small town in Texas.

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.

This study investigated the effects of verbal and graphic feedback alone and in combination with praise on the data-recording behavior of 12 direct care trainers (DCTs) who recorded their reinforcer deliveries as they interacted with mentally retarded clients. An additional variable examined was the effect of time of delivering feedback on subsequent data-recording behavior. Feedback was delivered by the experimenter. Correspondence checks were conducted and a three-phase multiple condition experimental design was used. All feedback conditions produced an observable difference in DCT data-recording behavior. Time of delivery of feedback also appeared to have an effect on the amount of data recorded by DCTs.

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.

Many granular materials, including sedimentary rocks and soils, contain clay particles in the pores, grain contacts, or matrix. The amount and location of the clays and fluids can influence the mechanical and hydraulic properties of the granular material. This research investigated the mechanical effects of clay at grain-to-grain contacts in the presence of different fluids. Laboratory seismic wave propagation tests were conducted at ultrasonic frequencies using spherical glass beads coated with Montmorillonite clay (SWy-1) onto which different fluids were adsorbed. For all bead samples, seismic velocity increased and attenuation decreased as the contact stiffnesses increased with increasing stress demonstrating that grain contacts control seismic transmission in poorly consolidated and unconsolidated granular material. Coating the beads with clay added stiffness and introduced viscosity to the mechanical contact properties that increased the velocity and attenuation of the propagating seismic wave. Clay-fluid interactions were studied by allowing the clay coating to absorb water, ethyl alcohol, and hexadecane. Increasing water amounts initially increased seismic attenuation due to clay swelling at the contacts. Attenuation decreased for higher water amounts where the clay exceeded the plastic limit and was forced from the contact areas into the surrounding open pore space during sample consolidation. This work investigates …
