The Analysis of Fire Debris Using Nuclear Magnetic Resonance Spectroscopy (open access)

The Analysis of Fire Debris Using Nuclear Magnetic Resonance Spectroscopy

This paper describes a new technique for analyzing fire debris using nuclear magnetic resonance (NMR) spectroscopy. Petroleum distillates, which are commonly used accelerants, were weathered, burned, and steamdistilled. These, as well as virgin samples of the accelerants, were analyzed by gas chromatography and nuclear magnetic resonance spectroscopy. In addition, solvent studies and detectibility limit studies were conducted. The use of NMR is described as a valuable adjunct to the existing methods of analysis.

Application of a Vibrotactile Aid in Improvement of Speech Production in Deaf Children (open access)

Application of a Vibrotactile Aid in Improvement of Speech Production in Deaf Children

The SRA-10 is a tactile instrument which provides hearing impaired subjects with acoustic transforms that can be easily discriminated on the skin. Whether or not the SRA-10 is an effective means of training speech-language skills in profoundly hearing impaired subjects was the focus of this investigation. Two profoundly hearing impaired subjects were trained on phonetic reception/production tasks and on discrimination of multisyllabic words. Each subject served as his own control, wearing the SRA-10 for 14, 30 minute sessions, and a Bioacoustics 70-B auditory training unit for the same period of time. Results indicated a greater correct performance gain function with the SRA-10 than with the 70-B, suggesting that speech perception/production training using the SRA-10 or similar device would be superior to training using acoustic amplification.

The Artist's Book as an Alternative to the Gallery Installation (open access)

The Artist's Book as an Alternative to the Gallery Installation

I examined and evaluated three sets of gallery installations and related handmade books. The following questions were considered foremost: 1) Visually, how different from and how similar to the gallery installations are the books? 2) What verbal elements are adapted from the installations to the books? 3) How does the difference in format (that is, the books) alter or affect the content and meaning of the installations?

Attitudes and Integration: A Survey of Selected Texas Camp Directors (open access)

Attitudes and Integration: A Survey of Selected Texas Camp Directors

This investigation dealt with the relationships between three main variables: (1) a camp director's prior experience with handicapped individuals and in the field of recreation; (2) a camp director's attitudes toward handicapped persons and their integration into regular camp settings; and (3) a camp director's perception of barriers to integration. The study was carried out via a mail-out questionnaire to 149 Texas camp directors. A return rate of 51% was achieved (66 returned surveys). Questionnaires were scored, and the data were punched on computer cards for analysis. The analysis indicated high reliability of the attitude and barrier scales. Results of the correlational analyses indicated a significant relationship (p = .0001) between a camp director's attitudes and his/her perception of barriers to integration.

Attitudes Toward Shopping for Apparel and Apparel Shopping Behavior of a Selected Group of Working Women (open access)

Attitudes Toward Shopping for Apparel and Apparel Shopping Behavior of a Selected Group of Working Women

The purposes of this study were to investigate attitudes toward apparel shopping and apparel shopping behavior of a selected group of working women in the Dallas, Texas, area. The study also examined relationships of occupation, education, age and marital status to apparel shopping attitudes and behavior. The study concluded that working women enjoy shopping for apparel but do encounter certain frustrations. Working women shop for apparel every few weeks or more and most often purchase apparel in department stores. The majority use charge accounts and often purchase apparel at reduced prices. Chi square analysis revealed few significant relationships between attitudes toward apparel shopping and apparel shopping behavior and the demographic variables of occupation, education, age and marital status.

Brain Dysfunction Indication on the Bender-Gestalt Test: a Validation of the Embree/Butler Scoring System (open access)

Brain Dysfunction Indication on the Bender-Gestalt Test: a Validation of the Embree/Butler Scoring System

The Embree/Butler scoring system served as criterion for ascertaining brain dysfunction on the protocols of 100 subjects--50 had been diagnosed by health professionals as having brain dysfunction, and 50 had been diagnosed as having no brain dysfunction. In comparing the hospital's diagnoses with those of the Embree/Butler method, the data strongly supported the hypothesis that the Embree/Butler scoring system did effectively discriminate (chi square of 77.99 < .01) between those with organic brain syndrome (or cerebral dysfunction) and those with psychiatric classification. A point-biserial correlation was used to distinguish the relationship between diagnosis and the score. A cutoff score of above 14 produced the least false-negative or false-positive evaluations.

Changes in Racial Attitudes as a Function of Personality Characteristics and Exposure to a Competent Black (open access)

Changes in Racial Attitudes as a Function of Personality Characteristics and Exposure to a Competent Black

The present study examined whether a relationship exists between level of rigidity and prejudicial attitudes and whether prejudiced attitudes could be modified as a function of exposure to a competent black model. It was predicted that individuals with a high level of rigidity would display more racial prejudice than low-rigid individuals and that individuals with a low level of rigidity would demonstrate less prejudice than high-rigid individuals after exposure to a competent model. After exposure to a competent model, a significant main effect for rigidity was found which indicated that low-rigid individuals became less prejudiced than high-rigid individuals,

The Chilean Experience, 1970-1981 (open access)

The Chilean Experience, 1970-1981

The election of a coalition of socialists and communists in 1970 and three years later, the assumption of a military government have led to much controversy around the world. This study attempts to analyze the economic conditions prevailing in Chile from 1970 to 1981. It examines the gradual deterioration of the nation's economy under the Unidad Popular government and the recovery that has taken place with the Junta Militar de Gobierno. The implementation of a market system in 1973 has been effective in bringing the nation out of economic chaos. The balance of payments is under control, inflation has been reduced, and since 1977 the nation's GNP has had an average annual growth of 7.7 per cent.

Combining Electroformed Copper and Raku (open access)

Combining Electroformed Copper and Raku

A major emphasis in my graduate studies in ceramics at North Texas State University has been on the production of raku wall pieces. Raku appealed to me for its unusual metallic glaze effects and the accidental qualities of the glazes and clay bodies due to the smoking reduction that takes place after the piece is removed from the kiln. During this same period I was also interested in and experimenting with the use of electroforming as a method of jewelry making. Again, the accidental qualities of this process were appealing. It was during these experiments, especially those involving non-conductive surfaces, that i frist considered applying the process to large ceramic pieces. The stoneware pieces were limited in size since they were to be developed into pieces of jewelry.

A Comparison of the Editorial Practices of Religious Magazines with Editorial Practices Described in Magazine Textbooks (open access)

A Comparison of the Editorial Practices of Religious Magazines with Editorial Practices Described in Magazine Textbooks

This study sought to determine the demographics of the managing editors of the 111 religious magazines listed in the 1981 edition of Writer's Market and the similarity of those magazines' editorial practices to editorial practices described in magazine textbooks. The sixty-four managing editors who answered the questionnaire tended to be college-educated, to say their chief motivation for working on a religious magazine was serving God and man and to be satisfied with their work. Twenty-five per cent of the managing editors in the study had undergraduate majors or master's degrees in journalism. The magazines' self-reported editorial practices in such areas as copy handling, proofreading, layout and design were similar to those described in magazine textbooks.

A Comparison of United States Network Television News Coverage of Sub-Sahara Africa Before and After the 1975-76 Angola Conflict (open access)

A Comparison of United States Network Television News Coverage of Sub-Sahara Africa Before and After the 1975-76 Angola Conflict

The proposition that American network television news coverage of sub-Sahara Africa increased substantially after the 1975-76 Angola conflict is examined in this study of the responsiveness of television to changing news values at the international level. News coverage for two thirty-month periods before and after the Angola conflict is compared using data derived from the Television News Index and Abstracts. The study finds that network news coverage of sub-Sahara Africa increased from 0.36 per cent of total news time before the Angola conflict to 4.46 per cent after, indicating that network news coverage is a reflection of the intensity of United States government activity at the international level.

Compositions in Clay and Rhythm

I constructed ceramic/mixed media instruments, recorded rhythmic music composed for and played on my instruments, and prepared a slide presentation portraying my daily rituals a studio artist. I describe in this paper the process involved in creating this environment and give an interpretation of the work by answering the following questions. 1. What were the rituals that were essential to the creation of my work? 2. In what ways did the use of the different visual and audio media work together to create a unified environment? 3. In what ways was the total experience of the different media a more direct and fulfilling expression of my goals as an artist, or are these goals better fulfilled when working in one media?

A Computer Assisted Micro-Dye Uptake Interferon Assay System

A new rapid computer assisted micro-titer plate interferon assay system was developed and characterized for use in high capacity clinical and research applications. The biological aspect of the assay was a modification of the assay methods of Finter, Armstrong and McManus. It was an application of spectrophotometric quantification of the reduction of viral cytopathic effect (CPE) as reflected by neutral red dye uptake by viable cells. A computer program was developed for the extrapolation of raw data to reference interferon units.

A Description of Progress in Expressive Language and Literacy of Four Young Children Learning English as a Second Language (open access)

A Description of Progress in Expressive Language and Literacy of Four Young Children Learning English as a Second Language

Four young children who were learning English as a second language were observed during their participation in an English Language Development class in a school in the North Texas area. Demographic data and checklists were used to describe progress in expressive language and the key vocabulary approach to beginning literacy as adapted by Trietsch and Monk. Data from the interviews with the classroom teachers of the subjects and anecdotal records were used to describe the interaction of the subjects with other English-speaking children and adults. Comparisons were made between progress in writing the key vocabulary and progress in expressive language and between progress in writing the key vocabulary and the progress of interaction with other English-speaking children and adults. The subjects progressed in literacy in English as a second language while learning English as a second language.

Determination of Biotransformation and Biodegradation Rate Constants for Naphthalene, Lindane and Phenol (open access)

Determination of Biotransformation and Biodegradation Rate Constants for Naphthalene, Lindane and Phenol

Biotransformation and biodegradation rate constants were determined for naphthalene, lindane, and phenol in water samples from three different sources. Rate constants produced from monitoring disappearance of the parent chemical (biotransformation) were compared to those obtained from mineralization of the chemical (ultimate biodegradation) by ¹⁴CO₂ evolution as well as acidification of the residual ¹⁴C-labeled compound (primary biodegradation). Rate constants were statistically different for the three chemicals. The water source affected the rate constants. When biomass measurements of the waters were considered and second-order rate constants were derived, there was no statistical evidence that this parameter gave a reliable rate constant statistic that could be useful in predicting the fate of any of naphthalene, lindane, and phenol in these waters.

The Determination of Uptake and Depuration Rate Kinetics and Bioconcentration Factor of Naphthalene and Lindane in Bluegill Sunfish, Lepomis macrochirus (open access)

The Determination of Uptake and Depuration Rate Kinetics and Bioconcentration Factor of Naphthalene and Lindane in Bluegill Sunfish, Lepomis macrochirus

Bluegill were exposed to 3 and 30 pg/L lindane and 20 and 200 pg/L naphthalene to determine uptake rate constants, K1 depuration rate constants, K2, and bioconcentration factors, BCF. Correlations were determined between lipid normalized and non-lipid normalized BCFs, and between observed Kl, K2 and BCFs and predicted values. The K1 values for both chemicals and concentrations were similar. The K2 values were different (1.04 day~1, 0.46 day 1). Naphthalene was more rapid. BCFs for lindane (315) and naphthalene (98) were different. Lipid normalized BCFs for naphthalene were more variable than non-lipid normalized BCFs. The reverse was observed for lindane BCFs. Predicted K1, K2 , and BCFs were in agreement with observed values.

Development and Evaluation of a Behaviorally Anchored Rating Scale as a Measure of Secretarial and Clerical Performance (open access)

Development and Evaluation of a Behaviorally Anchored Rating Scale as a Measure of Secretarial and Clerical Performance

Empirical findings on Behaviorally Anchored Rating Scales (BARS) have been mixed, despite early researchers' claims that BARS were superior to trait ratings and in reliability and resistance to leniency, central tendency, and halo. The study presented compared a BARS format to an independently derived trait scale as measures of secretarial and clerical performance. Though the BARS showed slightly inflated mean ratings, the instruments showed nearly identical variability. Neither demonstrated sufficient resistance to halo. Thus, despite their intuitive appeal and the rigors involved in format development, it did not appear in this instance that BARS were an efficient and psychometrically superior alternative to the traditional trait rating format.

Dmitri Shostakovich and the Fugues of Op. 87: A Bach Bicentennial Tribute (open access)

Dmitri Shostakovich and the Fugues of Op. 87: A Bach Bicentennial Tribute

In 1950-51, for the bicentennial of the death of J. S. Bach, Dmitri Shostakovich wrote his collection of Twenty-four Preludes and Fugues, Op. 87. This thesis is a study of the fugal technique of Shostakovich as observed in Op. 87, in light of the fugal style of Bach as observed in The Well-Tempered Clavier, Volume One. Individual analyses of each of the twenty-four Shostakovich pieces yield the conclusion that Op. 87 is an emulation of Bachian fugal methods as observed in The Well-Tempered Clavier, Volume One.
