Development and evaluation of a behaviorally anchored rating scale as a measure of secretarial and clerical performance

Description: 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.

Synthesis of aziridine analogues of pyrethroids

Description: Rules which correlate structure and insecticidal activity of pyrethroids have evolved over the last thirty years from the results obtained in the testing of various synthetic pyrethroids. The major portion of these rules have dealt either with the development of new alcohol moieties or variations in the unsaturated side chain of the cyclopropane ring. There has been very little work done concerning modifications of the cyclopropane ring. This study was initiated to discover the affect of substituting an aziridin ring for the cyclopropane ring found in pyrethroids.

Effects of interviewer's impersonal and personal self-disclosures on somatic symptom verbalizations of psychiatric outpatients

Description: A literature review indicated that psychopathological symptomology must be considered within the social context of the patient. Recent research has suggested that the psychopathological symptoms of the psychotic patient function on a covert level of communication as a strategy to control the threat of interpersonal intimacy. The present investigation similarly examined the interpersonal function of another class of patient symptomology, somatic symptoms.

High pressure HC1 conversion of cellulose to glucose

Description: The production of ethanol from glucose by means of fermentation represents a potential long-range alternative to oil for use as a transportation fuel. Today's rising oil prices and the dwindling world supply of oil have made other fuels, such as ethanol, attractive alternatives. It has been shown that automobiles can operate, with minor alterations, on a 10% ethanol-gasoline mixture popularly known as gasohol. Wood has long been known as a potential source of glucose. Glucose may be obtained from wood following acid hydrolysis. In this research, it was found that saturating wood particles with HCl gas under pressure was an effective pretreatment before subjecting the wood to dilute acid hydrolysis. The pretreatment is necessary because of the tight lattice structure of cellulose, which inhibits dilute acid hydrolysis. HCl gas makes the cellulose more susceptible to hydrolysis and the glucose yield is doubled when dilute acid hydrolysis is preceded by HCl saturation at high pressure. The saturation was most effectively performed in a fluidized bed reactor, with pure HCl gas fluidizing equal volumes of ground wood and inert particles. The fluidized bed effectively dissipated the large amount of heat released upon HCl absorption into the wood. Batch reaction times of one hour at 314.7 p.s.i.a. gave glucose yields of 80% and xylose yields of 95% after dilute acid hydrolysis. A non-catalytic gas-solid reaction model, with gas diffusing through the solid limiting the reaction rate, was found to describe the HCl-wood reaction in the fluidized bed. HCl was found to form a stable adduct with the lignin residue in the wood, in a ratio of 3.33 moles per mole of lignin monomer. This resulted in a loss of 0.1453 lb. of HCl per pound of wood. The adduct was broken upon the addition of water. A process design and economic evaluation for ...

Population Dynamics of Macrobenthos in a Regulated Stream 1970-71 and 1978

Description: Stability of the macrobenthic community in a regulated section of the Brazos River, Texas, was evaluated. Physicochemical data and information on spatial distribution of macrobenthos were collected. Populations of two invertebrate species, Isonychia sicca and Neoperla clymene, had been greatly reduced since 1970-71 and I. sicca had been practically eliminated from this section of the Brazos. Three other insect populations, Choroterpes mexicanus, Cheumatopsche campyla and Cheumatopsyche lasia, had more than doubled their numbers since the 1970-71 study. A physicochemical gradient existed in this regulated section of the Brazos but it appeared to have changed little in comparison of earlier chemical data. A gradation of the macrobenthic community was evident as distance from the dam increased,

Rheumatoid Arthritis: A Follow-Up Assessment of Physical Functioning Abilities After Treatment in a Comprehensive Environmental Control Unit

Description: Two instruments were developed and administered to fifteen female and three male rheumatoid arthritics (mean age 44) previously hospitalized for allergy treatment by ecological methods. The Physical Functioning Ability Scale assessed functional capacity according to common daily activities, and the Rehabilitation Questionnaire surveyed adjustment problems subjects encountered after hospital discharge. ANOVA was performed on the functionality scale comparing dimensions of dependence, pain, and difficulty with categorical activities of mobility, work, and personal care, Significant F values (p(.05) were obtained for interaction and dimensions, but not for categories. Functional independence from human/mechanical assistance was particularly noted. Recommendation for future research concerns replicating this study using a control group of rheumatoid arthritics treated by traditional medical approaches.

Skin Pigmentation Influencing Perception of Mexican-Americans

Description: Subjects were 101 Mexican-American adults (53 females, 48 males), age range 17-72, and most often were in the blue-collar job level. Instructions were that (a) 18 pairs of slides would be shown; (b) each slide would be projected for 15 seconds; (c) each of the two models was to be judged on intelligence, attractiveness, friendliness, happiness, and success; and (d) the rating scale would be marked corresponding to the left or right slide. Results indicated the lighter-skinned models were judged more favorably than the darker ones on all five dimensions. To the extent this study sheds light on an important cultural value, it is hoped the treatment of Mexican-Americans in therapy will be facilitated and improved.

Student Attitudes Toward Reading Following Computer-Assisted Reading Instruction

Description: The problem investigated in this study was whether students who received computer-assisted reading instruction would display positive attitudes toward reading six or more months after the instruction was completed. A Likert attitude scale was administered to thirteen pre-adolescent and adolescent subjects to assess their attitudes toward reading six or more months after they had received computer-assisted instruction (CAI). In addition, a questionnaire was administered to the subjects' parents to determine their perception of the subjects' attitudes toward reading. Data obtained from the Likert scale indicated that the subjects' attitudes toward reading were neutral. An analysis of responses to the parent questionnaire revealed that the students' attitudes toward school-related reading were positive as a result of CAI. This study concluded that CAI had no apparent positive impact on the subjects' attitudes toward recreational reading.

A Survey of Selected Chinese Students in the United States to Determine How They Receive Hometown News

Description: The problem of this study was to determine how Chinese students obtain news from home. The study was conducted in Dallas, Fort Worth, and Denton, with 182 respondents from six universities. The study determined that Chinese students obtained Chinese news from Chinese newspapers circulating in the United States. The longer Chinese students remained in the United States, the fewer letters they received from home and the fewer newspapers and clippings their family and friends sent them. The conclusion of the study was that Chinese students read Chinese newspapers because they wish to maintain ties with their hometown and culture. Students stated that Hong Kong local news was their primary item in reading Chinese newspapers.

An Historical Analysis of the Macquarie Broadcasting Service Pty. Ltd., Sydney, Australia, 1938-1958

Description: Australia's dual system of broadcasting has provided national and commercial radio services to Australians in both urban and remote areas. Networks were formed to serve these areas, but advertising agencies tended to dominate smaller commercial networks on behalf of their clients. Most of these failed. The Macquarie Broadcasting Service Pty. Ltd. (MBS) network began in 1938 and offered network programming and sales representation to stations affiliating with them. Its subsidiary, Artransa Pty. Ltd., also produced and syndicated programs and provided sales representation both nationally and internationally. This study concludes that MBS' contribution to Australian commercial broadcasting was the development of networking and that it had the greater listenership of any commercial network in this time period.

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

Description: 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.

The Regulation of HMG-CoA Reductase by Enzyme-Lipid Interactions

Description: The temperature-dependent catalytic activity of rat liver 3-hydroxy-3 -methylglutaryl coenzyme A reductase (HMG-CoA reductase) displays the nonlinear Arrhenius behavior characteristic of many membrane-bound enzymes. A two-conformer equilibrium model has been developed to characterize this behavior. In the model, HMG-CoA reductase undergoes a conformational change from a low specific activity to a high specific activity form. This conformation change is apparently driven by a temperature-dependent phase transition of the membrane lipids. It has been found that this model accurately describes the data from diets including rat chow, low-fat, high-carbohydrate, and diets supplemented with fat, cholesterol or cholestyramine. The effects characterized by the model are consistent with the regulation of HMG-CoA reductase by enzyme-lipid interactions.

Police Attitudes Toward Rape

Description: Research has demonstrated that the general public accepts many rape myths and that rape attitudes are strongly connected to other deeply held and pervasive attitudes. However, it has not been clear whether police officers reflected similar attitudes. This research attempted to ascertain if police share the same antecedents of rape myth acceptance as the general public. Using officers from two police departments, it was demonstrated that attidudes regarding sex role stereotyping, sexual conservatism, acceptance of interpersonal violence, and adversarial sexual beliefs were significantly correlated with acceptance of rape myths. However, police were more pro-victim (p < .01) in their attitudes as compared to the general public. Officers who received specialized rape-related training were not significantly different in rape attitudes from those officers who had not received training.

The Effect of Ozonation in Reducing Trihalomethane Formation Potential

Description: Trihalomethanes such as chloroform, dichlorobromomethane, dibromochloromethane, and bromoform are formed when natural water is chlorinated in water treatment. This investigation explores the use of ozone to remove organic precursors from natural water, thus decreasing trihalomethane formation potential. The data suggest a mechanism involving formation of secondary precursors after prolonged contact with ozone, suggesting that trihalomethane precursors may be minimized by using low doses of ozone and short contact time.

A Study of the Public Relations Structures and Activities at Selected Dallas Hotels

Description: The study was designed to identify the public relations structures at eight Dallas hotels, their functions and activities, and if public relations effectiveness is evaluated. Findings were based on sixteen interviews with senior management and public relations coordinators. The study concluded that public relations programs are structured by either separate public relations department, public relations activities combined with other department, or an external agency. The public relations functions range from image-building to participation in sales and marketing with primary responsibility of promotion and publicity dominated by economic considerations. One weakness is the lack of formal research methods to discern public opinion. There is a lack of understanding by hotel management of the potential and scope of public relations programs.

Robert Grosseteste as Mentor to William of Shoreham

Description: The problem scrutinized in this thesis is the relationship between Robert Grosseteste, mentioned in the colophon of William of Shoreham's "Song to Mary," and the author of said poem. The influence of Grosseteste on William of Shoreham appears to be extensive. Many similarities of organization, diction, and, especially, imagery, exist in the works of both men. The images of the windowpane, the mirror, and Mary as a castle are found in more than one instance in both Grosseteste's Chasteau d'Amour and in several of Shoreham's poems. Moreover, the borrowed imagery in Shoreham's poetry is unquestionably superior to any other in his works. It is the conclusion of this thesis that Robert Grosseteste was a considerable influence on the works of William of Shoreham.

Validity Scale Elevation in Factor Analysis of the MMPI-168

Description: In a statistical comparison of orthogonal normalized varimax factor analytic solutions for the MMPI-168 including and excluding invalid protocols of psychiatric inpatients, at least one factor reflection was observed. Factors identified were Psychotic Distortion (Absence of Distress), Somaticism, Depression, Extroversion, Masculinity-Femininity, and Low Morale. Factors obtained, and representative clinical scales, were consistent with those obtained by others in investigations of both abbreviated and standard MMPI forms. Statistical comparison of factors identified by the two analyses indicated congruence. Possible sources of factor distortion were discussed.
