A Comparison of Academic Achievement of Boys and Girls from Full-Day and Half-Day Kindergartens

A Comparison of Academic Achievement of Boys and Girls from Full-Day and Half-Day Kindergartens

Date: December 1987
Creator: Tabb, Juanita K. (Juanita Kay)
Description: The purpose of this study was to determine whether any differences in academic achievement existed between full-day and half-day kindergarten students at the end of their kindergarten and first-grade school years. Two public schools considered comparable in size, philosophy, and socioeconomic levels of a large school district in Texas participated in the study. One of the schools provided a full-day kindergarten program; the other school provided a half-day kindergarten program. Kindergarten students from each of the two schools were match-paired according to birthday and sex. The total sample size was fifty students. All students were tested in December, 1985, with the Metropolitan Achievement Test. Preprimer Level, and in May, 1986, the end of the kindergarten year, with the Primer Level of the Metropolitan Achievement Test. The Metropolitan Achievement Test. Primary I Level, was additionally administered to the subjects in April, 1987, at the end of their first-grade school year. During each testing period, the subjects were administered the Reading, Language, and Math subtests of the Metropolitan Achievement Test. The following supplemental data also were gathered on the students: The Metropolitan Readiness Test II scores and the TEAMS test scores. The data obtained from the testing batteries were statistically analyzed using ...

Alcohol Use among the Elderly in Edmonton, Alberta: a Multivariate Analysis

Alcohol Use among the Elderly in Edmonton, Alberta: a Multivariate Analysis

Date: May 1989
Creator: Watson, Jack Borden
Description: A model of social stressor variables, social integration variables and demographic control variables was tested to assess their impact on alcohol use among the elderly. A secondary analysis of a survey on alcohol use among the elderly in Edmonton, Alberta, Canada, was conducted to test the major hypotheses of the study. Contingency table analysis, using gamma and partial gamma as correlation coefficients, was utilized in the data analysis. The first hypothesis, in regard to the positive relationship of social stressors with alcohol use, was confirmed. The best predictors of alcohol use among the social stressor variables were usual occupation, length of retirement, annual income, and subjective health status. The second hypothesis, that the social integration variables would be negatively related to alcohol use, received only moderate support. The results of the analysis indicated that six of the ten social integration variables were negatively related to alcohol use. Only three of these variables, retirement status, religious participation, and marital status, were statistically significant. Hypothesis three also was not confirmed. The introduction of the social integration variables did not substantially decrease the strength of the relationship between social stressors and alcohol use. Gender and age were also introduced as control variables for ...

Group Counseling as an Intervention in Anger Expression and Depression in Older Adults

Group Counseling as an Intervention in Anger Expression and Depression in Older Adults

Date: December 1988
Creator: Johnson, Wanda Y. (Wanda Yates)
Description: Depression is believed to be the most prevalent mental dysfunction among older adults, and depression and anger are frequently linked in theory and in therapy. This study was undertaken to determine whether participation in group counseling sessions would increase awareness and expression of anger and decrease depression levels in women aged 65 and older. Treatment group members were compared to a matching control group. Both groups completed the Anger Self Report Questionnaire and the Beck Depression Inventory. Comparison of the ASR subscale scores, Awareness of Anger, Expression of Anger, Guilt, Condemnation of Anger, and Mistrust, revealed no significant differences between the treatment and control groups. However, the treatment group scored significantly higher on the BDI than did the control group. Analysis of variance of the ASR and the BDI, and the variables upon which the treatment and control groups were matched revealed some significant differences, and comparison of the women in this study with the two groups upon whom the ASR was validated showed this study's older women scored significantly lower than the validation groups on the ASR. The author concluded that six sessions is not long enough to effect change in either anger awareness or expression in older women, ...

The Local Economic Impact of Alternative State Budget Reductions for Selected Texas Community Colleges

The Local Economic Impact of Alternative State Budget Reductions for Selected Texas Community Colleges

Date: May 1988
Creator: Saleh, Abdelrahim
Description: The purpose of this study was to determine the local economic impact of alternative state budget reductions for Texas community colleges by investigating the income losses to the Metropolitan Statistical Areas (MSAs) if state appropriations were reduced by 10, 15, and 20 percent. The objective of this study was achieved through an economic analysis of the local economy of selected MSAs and by computing the income size which was generated by selected colleges. Eight community colleges located in eight MSAs participated by answering mailed questionnaires. The model of Direct Economic Impact was applied to describe the colleges' economic impact. The model was composed of college expenditures, employee expenditures, student expenditures, and the economic multiplier. The study revealed that the selected community colleges were responsible for creating new jobs and increasing the income of the local economies. These eight colleges were responsible for increasing the income of the local economies by $294,945,560 and for creating 5,129 jobs. Reduction in state appropriations to the selected community colleges will reduce the income they produce. A state appropriation cut of 10 percent will result in a loss to the local economy of $6,153,951. A 15 percent reduction in state appropriations will cause the local ...

Molecular Dynamics in the Liquid Phase by FT-NMR, FT-IR and Laser Raman Lineshape Analysis

Molecular Dynamics in the Liquid Phase by FT-NMR, FT-IR and Laser Raman Lineshape Analysis

Date: August 1988
Creator: Chen, Fu-Tseng Andy
Description: Nuclear magnetic resonance (NMR) provides a convenient probe for the study of molecular reorientation in liquids because nuclear spin-lattice relaxation times are dependent upon the details of molecular motion. The combined application of Raman and Infrared (IR) lineshape analysis can furnish more complete information to characterize the anisotropic rotation of molecules. Presented here are the studies of NMR relaxation times, together with Raman/IR Mneshape analysis of the solvent and temperature dependence of rotational diffusion in 1,3,5-tribromobenzene and 1,3,5-trifluorobenzene. In these experiments, it was found that the rotational diffusion constants calculated from Perrin's stick model were two to three times smaller than the measured values of D, and D,,. Similarly, rotational diffusion constants predicted by the Hu-Zwanzig slip model were too large by a factor of 2. Application of the newer Hynes-Kapral-Weinberg model furnished rotational diffusion constants that were in reasonable agreement with the experimental results. The vibrational peak frequencies and relaxation times of the isotropic Raman spectra of the Ď…1 modes of CD2Br2 and CHBr3 were studied in solution. The frequency shifts in non-interactive solvents were explained well on the basis of solution variations in the dispersion energy. In Lewis bases, the displacements were in some, but not all, cases ...

An Analysis of Smoothing of Proved Oil and Gas Reserve Quantities and an Analysis of Bias and Variability in Revisions of Previous Estimates of Proved Oil and Gas Reserve Quantities

An Analysis of Smoothing of Proved Oil and Gas Reserve Quantities and an Analysis of Bias and Variability in Revisions of Previous Estimates of Proved Oil and Gas Reserve Quantities

Date: August 1988
Creator: Campbell, Alan D.
Description: The purpose of this study is to determine whether oil and gas producing companies smooth their ending reserve quantities. Smoothing is defined as a reduction in variance in the trend of ending reserve quantities over time compared to the trend of ending reserve quantities less the hypothesized smoothing variable over time. This study focuses on two variables that are most susceptible to manipulation—revisions of previous estimates and additions. This study also examines whether revisions are positively or negatively biased and the variability of the revisions. The sample consists of 70 companies chosen from oil & Gas Reserve Disclosures: 1980-1984 Survey of 400 Public Companies by Arthur Andersen and Company. For each company, ending reserve quantities for the years 1978-1984 were regressed over time, and the standard deviation of the estimate (SDE) was calculated. Then the ending reserve quantities less the hypothesized smoothing variable were regressed over time, and the SDE was calculated. A linear model and a semi-logarithmic model were used. A smoothing ratio (SR) was determined by dividing the SDE of reserves less the hypothesized smoothing variable by the SDE of ending reserve quantities. An SR greater than one indicates smoothing, and an SR less than one indicates that ...

The Relative Value and Importance of Perceived Benefits of Active Foundations of Public Community Colleges in the United States

The Relative Value and Importance of Perceived Benefits of Active Foundations of Public Community Colleges in the United States

Date: August 1988
Creator: Henry, Elizabeth H. (Elizabeth Henderson)
Description: The problem of this study was the relative value and importance of perceived benefits of active foundations of public community colleges. The purposes were to identify a list of benefits; determine the importance of these benefits as perceived by presidents and foundation executive directors; assess the degree to which the level of importance of the benefits was affected by college or foundation demographics or foundation executive director characteristics; and to determine if presidents and foundation executive directors differ in their perceptions of the importance of the benefits. Survey instruments were mailed to presidents and foundation executive directors of colleges determined to have active foundations. Both instruments contained seven categories listing potential benefits to the community colleges of an active foundation. The foundation executive directors' instruments also requested college and foundation demographic data. Respondents were asked to rate the benefits according to their level of importance. Analysis of variance tests were performed to determine whether the categories of benefits were affected by any of the demographic data, when a level of significance emerged, a Scheffe' test was performed to determine the source of significance. Major findings were that the most important single benefit to the community colleges of active foundations is ...

Information Content of Managerial Decisions, Change in Risk, and Complimentary Signals: Evidence on New Bond Issue, Exchange Offer, and Dividend Payments

Information Content of Managerial Decisions, Change in Risk, and Complimentary Signals: Evidence on New Bond Issue, Exchange Offer, and Dividend Payments

Date: August 1988
Creator: Iqbal, Zahid
Description: The effect of a change in capital structure on the risk and return of common stockholders is investigated. Also, the information content of dividends when a firm goes for new outside financing is examined. Data used in the study are collected from the Moody's Bond Survey, the Prentice Hall's Capital Adjustments, the Wall Street Journal Index, and the Center for Research in Security Prices Tape. The study uses an event study methodology. The risk (beta) of common stock before an issuance of debt securities is compared with the risk after the issue. The stock market reaction to the issuance of new debt securities is measured using after-the-event risk. The information content of dividend announcement before a new debt issue is compared to that of after the issue. The findings show that debt issue reduces stock holders' risk if the issuer is a dividend paying company. Also, debt securities issued through an exchange offer increase stockholders' wealth. Finally, issuance of new debt does not affect the information content of dividends.

The American University of Beirut and Its Educational Activities in Lebanon, 1920-1967

The American University of Beirut and Its Educational Activities in Lebanon, 1920-1967

Date: May 1988
Creator: Sayah, Edward
Description: The purpose of this study was to trace the historical development of the American University of Beirut and its educational contributions in Lebanon and the Middle East from 1920 to 1967. Through their activities in the Levant in the early nineteenth century, the American missionaries virtually laid the foundations of the Syrian Protestant College, later known as the American University of Beirut. Though religion was the cornerstone in the founding of the University, under the pressure of the local environment, its secular character was to be substituted for the religious one. The establishment of the University in 1866 marked the beginning of the system of higher education in the Arab world. As the first established institution of higher learning, the University played a significant role in raising the level of literacy throughout the region. Despite the difficult times that the University faced throughout its history, it survived and continued its dedicated mission to serve the people of Lebanon and the entire area. For the University, the first 50 years under Ottoman rule was a period of surviving and maintaining its existence. With the freedom it came to enjoy during the French Mandate and later during independence, the University moved into ...

Toward a Theory of Consumer Attitudes Regarding Products of Foreign Origin: a Multiattitude Expectancy-Value Approach

Toward a Theory of Consumer Attitudes Regarding Products of Foreign Origin: a Multiattitude Expectancy-Value Approach

Date: May 1988
Creator: Landeck, Michael
Description: This dissertation focuses generally on consumer behavior, and particularly on consumer attitudes toward products of foreign origin for the purpose of developing a theory that will assist in explaining and predicting this phenomenon. Existing research in the area of country of origin effects upon consumer attitudes toward foreign-made products demonstrates significant methodological limitations such as single cue approaches., The major objective of this dissertation is to contribute to the development of a theory based upon the expectancy-value attitude concept to better explain and predict consumer attitudes toward products of foreign origin. To achieve this objective, the research attempts to overcome the limitations identified in attitude research and specific methodological deficiencies in research focusing on attitudes toward products of foreign origin by: 1. utilizing the expectancy-value approach; 2. basing operationalization of the attitude concepts on Likert-like scales and subjective conditional probabilities; 3. measuring the operationalized attitudes both directly and indirectly via beliefs and evaluations; 4. simultaneously including multiple extrinsic cues; 5. including pictorial cues in the questionnaire; and 6. performing and reporting validity and reliability tests. The general model developed in this research, representing the theory of attitudes toward products of foreign origin is the Foreign Product Attitude Model (FPAM). This ...
