Mechanism of the Adenosine 3',5'-Monophosphate Dependent Protein Kinase

Mechanism of the Adenosine 3',5'-Monophosphate Dependent Protein Kinase

Date: May 1988
Creator: Kong, Cheng-Te
Description: Isotope partitioning experiments were carried out with the adenosine 3',5'-monophosphate-dependent protein kinase catalytic subunit (cAPK) from bovine hearts to obtain information on the order of addition of reactants and the relative rates of reactant release from enzyme compared to the catalytic step(s). A value of 100% trapping for both ErMgATP-[γ-32P] and E:3H-Serpeptide at low Mgf indicates that MgATP and Serpeptide dissociate slowly from the enzyme compared to the catalytic step(s). The K_Serpeptide for MgATP trapping is 17 μM, while the K_MgATP for Serpeptide trapping is 0.58 mM. The latter data indicate that the off-rate for MgATP from the E:MgATP complex is 14 s^-1 while that for Serpeptide from the E: Serpeptide complex is 64 s^-1. At high Mg^, 100% trapping is obtained for the E:MgATP-[γ-32P] complex but only 40% is obtained for the E:Serpeptide complex. Thus, the off-rate for Serpeptide from the E:MgATP:Serpeptide complex becomes significant at high Mg_f. Data suggest a random mechanism in which MgATP is sticky. The V for the cAPK reaction increases 1.5-1.7 fold in the presence of the R_II in the presence of saturating cAMP at a stoichiometry of R:C of 1:1. No change is obtained with the type-I complex under these conditions. At higher ...

A Study of the Relationships between Employee Stock Ownership Plans and Corporate Performance

A Study of the Relationships between Employee Stock Ownership Plans and Corporate Performance

Date: May 1988
Creator: Robinson, Robert K. (Robert Kirkland)
Description: This work collected four years of financial data from an employee-owned firm and a traditionally-owned firm from the same industry. The data were then organized to provide measures of three dimensions of corporate performance: (1) employee turnover, (2) productivity, and (3) profitability. Based upon a review of the literature, employee stock ownership plans (ESOP) are reported to enhance corporate performance after their adoption. Additionally, ESOPs are purported to perform better than traditionally-owned companies. This dissertation developed hypotheses to ascertain whether or not the particular ESOP used in this study conformed to these expectations. The first set of three hypotheses was tested using multiple regression techniques to determine if the ESOP experienced a reduction in turnover, an improvement in productivity, and an increase in profitability following its conversion to employee-ownership. The results of the regressions found that there was no incremental significance. There was no improvement noted in the performance of the ESOP firm. Another component of this investigation was to determine whether improvements in corporate performance were temporary or permanent phenomena. This portion of the research was rendered superfluous when no improvements were available for analysis. The final question that was examined was whether the ESOP would demonstrate better performance ...

Piano Music of Native Chinese Composers, with Particular Focus on the Piano Works Since 1950: a Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, L.v. Beethoven, S. Prokofiev, F. Chopin, R. Schumann, J. Brahms, M. Ravel, and A. Skryabin

Piano Music of Native Chinese Composers, with Particular Focus on the Piano Works Since 1950: a Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, L.v. Beethoven, S. Prokofiev, F. Chopin, R. Schumann, J. Brahms, M. Ravel, and A. Skryabin

Date: May 1988
Creator: Yang, Shu-mei
Description: This documents aims at the identification of the sources of influence upon the styles of selected 20th century Chinese composers. Personal influences are reflected as well as those general influences specific to the different stylistic periods discussed. Most important, however, is the description of the methods by which these composers employ contemporary compositional devices to project musical gestures that are uniquely Chinese: elements of culture which are fundamentally programmatic and intimately related to the lives of the Chinese people. The introduction of Western music and musical instruments to China in the early 17th century and cultural exchanges with Japan served to gradually westernize the musical environment and training. The establishment of decidedly Western schools was accomplished at the beginning of this century, with the founding of Peking University and Shanghai National Conservatory. Music theory was taught, as well as history and composition, but with an emphasis on the practices of the 18th and 19th centuries. Compositions from this period reflect Western techniques from these eras, with some use of the pentatonic scale. In the 1930's, nationalism arose, a mirroring of the 19th-century European nationalistic trends. This philosophical conception has remained essentially unchanged to the present, as composers have aimed to ...

Characteristics of Development Directors in Charitable Homes for the Aged

Characteristics of Development Directors in Charitable Homes for the Aged

Date: May 1988
Creator: Wuenschel, Douglas F. (Douglas Ferdinand)
Description: This study concerns the characteristics of fund development directors employed in selected homes for the aged. The first purpose of this study is to develop a profile of job functions, through task analysis, among development directors in charitable homes for the aged. The second purpose of this study is to develop a profile of personal characteristics of development directors of charitable homes for the aged based on the following characteristics: age, sex, educational background, experience outside development, membership in community organizations and amount of specific training in fund development. One instrument was used to gather data for the study. It was distributed to a population of 29 development directors in charitable homes for the aged in Arkansas, Louisiana, Oklahoma, New Mexico, and Texas. This population was predetermined by an initial survey form sent to 193 chief executive officers in the five states mentioned above. Twenty-nine reported formalized programs employing a full-time person with at least a part-time involvement in fund development activities. Of the twenty-nine development directors surveyed, fifteen usable instruments were received (52 percent). A program was used for the survey that included crosstabulation of social characteristics, success in fund raising, length of time in position and educational preparation. ...

Factors Related to Travel Mode Choices in the Dallas-Fort Worth Metropolitan Area

Factors Related to Travel Mode Choices in the Dallas-Fort Worth Metropolitan Area

Date: May 1988
Creator: Karimpour, Abdolmehdi
Description: This study examined the factors related to travel mode choices in the Dallas-Fort Worth Metropolitan Area. Changes in population, life style and economy of the Dallas-Fort Worth region over the last few decades demand a careful re-examination of travel demand tools and methods. The purpose of the study was to provide an understanding of transportation modal choice in the region. Those demographic variables best predicting the choices were identified. The Home Interview Survey, a set of disaggregate data from the 19 84 North Central Texas Council of Governments (NCTCOG) Regional Travel Survey, was analyzed using logistic regression. The major findings of the research indicate that about 97 percent of the travelers in the study area used private cars and 3 percent used public transit. Household income and cars-vans were significant explanatory variables. The impact of household income and number of car-vans available upon an individual's decision for travel mode choice were very important. The number of car-vans available in the household, and age of respondents were significant predictors in travel mode. Household members with incomes of $30,000 to $39,000 and those with incomes of at least $50,000 tended to use more private cars than did other income groups. Also, household ...

Home Literacy Environment and Experiences: A Description of Asian American Homes and Recommended Intervention

Home Literacy Environment and Experiences: A Description of Asian American Homes and Recommended Intervention

Date: August 1988
Creator: Lewis, Junko Yokota
Description: The purpose of this study was to describe the home literacy environments and literacy experiences of a select group of Asian American children, and to recommend an intervention program based on the findings. The target population was the families which sent their children to a Saturday Asian language and culture school while sending them to public schools during the week, because of their expressed interest in literacy and the probability of their being the group to most likely benefit from intervention. The Home Literacy Environment and Literacy Experiences survey was initially sent out and results tallied and quantified. Upon placing the returned surveys into groups of "high," "middle," and "low" home literacy environment and literacy experiences, a sample of five "high" and five "low" families was selected for further study. Home visits, interviews, field notes, collection of artifacts and other methods of data collection provided a clearer picture of the state of the home literacy environment and literacy experiences of the families studied. Families rated as having "high" home literacy environment and experiences were found to have a larger number of literacy-related materials and higher frequency of literacy-related activities. Bilingualism and education were perceived as being important. The families also ...

Cognitive Indices of Criminal Thought: Criminals Versus Non-Criminals

Cognitive Indices of Criminal Thought: Criminals Versus Non-Criminals

Date: August 1988
Creator: Krusen, Richard Montgomery, 1954-
Description: The ability of several psychometric instruments to differentiate between criminal and non-criminal subjects was investigated. The subjects in the study consisted of fifty male individuals between the ages of 18 and 55, half of which had been convicted of one crime and half of which had no history of criminal activity. The tests administered consisted of the Psychopathic Deviation Scale from the Minnesota Multiphasic Personality Inventory (MMPI), the Psychopathic Deviation Scale of the Clinical Analysis Questionnaire, and two tests designed by the author. The author's tests consisted of the Test of Criminal Cognitions which evaluated antisocial thought patterns and cognitive flexibility, and the Social Semantics Test which assessed individual role definitions. The Test of Criminal Cognitions was administered as a part of a structured interview, and all other scales were administered in a paper and pencil format. The results indicated that the Psychopathic Deviation Scale of the MMPI, and a portion of both the Test of Criminal Cognitions and the Social Semantics Scales differentiated between the groups at the .05 level or better. These findings indicated that criminals tend to be significantly less flexible in their thought and tend to view others in a much more narcissistic manner than non-criminals. ...

History of Counseling Services in Hong Kong

History of Counseling Services in Hong Kong

Date: August 1988
Creator: Leung, Timothy Tin-ming
Description: The purpose of this study was to trace the development of the counseling movement in Hong Kong from its beginning to the present and to examine future directions confronting those who work in the counseling field in Hong Kong. Originating from social unrest in 1966 and 1967, the counseling movement began as an attempt to meet the society's developmental needs of self-expression and direction. Although not a formal program, the first known counseling service in Hong Kong was offered by Ben Fong in 1967 at the Yang Memorial Social Service Center. In 1969 the Hong Kong Federation of Youth Groups established the first formal counseling service in Hong Kong. Institutions of higher education and foreigners played a major role in the development of early counseling services in Hong Kong. In 197 0, Peter Whyte, an Australian, organized a counseling service at the University Hong Kong. In 1971, Ken Locke, an American, established a counseling service at the Hong Kong Baptist College. Counseling services grew rapidly in the early 1970s, and a 1975 survey identified fifty-five agencies which reported providing counseling services. In the mid-1970s, helping professionals were struggling with the issue of "What is counseling?" A significant developmental step was ...

A Comparison of Three Item Selection Methods in Criterion-Referenced Tests

A Comparison of Three Item Selection Methods in Criterion-Referenced Tests

Date: August 1988
Creator: Lin, Hui-Fen
Description: This study compared three methods of selecting the best discriminating test items and the resultant test reliability of mastery/nonmastery classifications. These three methods were (a) the agreement approach, (b) the phi coefficient approach, and (c) the random selection approach. Test responses from 1,836 students on a 50-item physical science test were used, from which 90 distinct data sets were generated for analysis. These 90 data sets contained 10 replications of the combination of three different sample sizes (75, 150, and 300) and three different numbers of test items (15, 25, and 35). The results of this study indicated that the agreement approach was an appropriate method to be used for selecting criterion-referenced test items at the classroom level, while the phi coefficient approach was an appropriate method to be used at the district and/or state levels. The random selection method did not have similar characteristics in selecting test items and produced the lowest reliabilities, when compared with the agreement and the phi coefficient approaches.

Hostile Environment: A Discriminant Model of the Perceptions of Working Women

Hostile Environment: A Discriminant Model of the Perceptions of Working Women

Date: August 1988
Creator: Kirk, Delaney, J.
Description: This study examines the problem of operationally defining "hostile environment" sexual harassment, ruled a type of disparate treatment actionable under Title VII of the Civil Rights Act by the United States Supreme Court on June 19, 1986. Although the Equal Employment Opportunity Commission defines a hostile environment as an "intimidating, hostile, or offensive work environment," there is no consensus as to what is "offensive" behavior. An extensive review of the literature yielded various attempts to define and ascertain the magnitude of sexual harassment, but the fact that the actual percentages varied indicates that this is a difficult issue to measure. As perception by the victim is the key, this study surveyed 125 working women from all over the United States to determine their perceptions of behaviors that constitute sexual harassment. Discriminant analysis was then used to correctly classify 95% of the women according to their perceptions of having experienced sexual harassment. Using tests for proportions, three hypotheses were found significant. Women who have been sexually harassed are more likely to view sexual harassment as a major problem. Older men are more likely to have their behavior perceived as sexual harassment. In addition, women who have experienced acts such as staring, ...
