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

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, and more time is needed to establish group cohesiveness in older populations than that generally thought to be needed for younger populations. Replication of the study with men and women, and replication of Khe study using a longitudinal design is recommended in order to determine whether awareness and expression of anger change with age, or whether differences between older and younger populations are due to historical and environmental influences.

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

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 economy to lose $9,230,943. A 20 percent reduction in state appropriations will reduce the local economic income by $12,307,920.

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

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 υ1 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 greater than predicted. On the other hand, it was found that the vibrational relaxation times of the C-H/C-D modes decreased dramatically in all Lewis base solvents. Therefore, it was concluded that relaxation times of the υ1 modes, rather than frequency shifts, furnish a more reliable measure of hydrogen bonding interactions of halomethanes in solution.

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

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 smoothing did not occur. The mean percentage revision and a t-test were used to test for positive or negative bias in the revisions. The mean absolute percentage revision was used to assess the relative variability of revisions. The number of companies classified as smoothers of oil reserves was statistically significant for the semi-logarithmic model but not for the linear model. Under both models the number of companies classified as smoothers of gas reserves was statistically significant. Few companies had mean percentage revisions that were significantly different from zero. The majority of companies had mean absolute revisions of under ten percent.

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

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 the provision of student scholarships. The "Public Relations/Political Influence" role of the active foundation is the most important category of benefits. The more fund-raising activities held and the greater the amount of contributions, the more positively community college administrators felt about the role of their active foundations in terms of external relations. Highly experienced foundation executive directors were more positive about the importance of the public relations role of their active foundations than were their inexperienced counterparts. The major conclusion of this study was that community colleges benefit from having active foundations, both monetarily and through the role of the ...

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

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

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 a period of advancing and expanding. By the 1960s the University had become a prestigious institution and captured the support of most people and governments in the area. The study's six chapters describe the historical setting of Lebanon and the origins of its religious groups, the historical background of the American University of Beirut, the educational activities of the University during the French Mandate, and its educational activities under independent Lebanon. The thesis showed that the University had a significant role in the education of the Lebanese and the peoples of the area, and that it has significantly contributed to ...

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

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 dissertation will concentrate on an extracted part of the total model, namely the relationships between the informational stimuli cues and the attitudinal response. The informational extrinsic informational cues include the country of origin, the brand name, the store image and an involvement covariate. By concentrating on the above relationships it is hoped that this study will contribute to a better understanding of the direct effects of the informational stimuli upon the attitude toward a product of foreign origin. The country of origin effect and the other extrinsic cues (brand name and store image) were found to have significant effects on ...

Operators on Continuous Function Spaces and Weak Precompactness

Description: If T:C(H,X)-->Y is a bounded linear operator then there exists a unique weakly regular finitely additive set function m:-->L(X,Y**) so that T(f) = ∫Hfdm. In this paper, bounded linear operators on C(H,X) are studied in terms the measure given by this representation theorem. The first chapter provides a brief history of representation theorems of these classes of operators. In the second chapter the represenation theorem used in the remainder of the paper is presented. If T is a weakly compact operator on C(H,X) with representing measure m, then m(A) is a weakly compact operator for every Borel set A. Furthermore, m is strongly bounded. Analogous statements may be made for many interesting classes of operators. In chapter III, two classes of operators, weakly precompact and QSP, are studied. Examples are provided to show that if T is weakly precompact (QSP) then m(A) need not be weakly precompact (QSP), for every Borel set A. In addition, it will be shown that weakly precompact and GSP operators need not have strongly bounded representing measures. Sufficient conditions are provided which guarantee that a weakly precompact (QSP) operator has weakly precompact (QSP) values. A sufficient condition for a weakly precomact operator to be strongly bounded is given. In chapter IV, weakly precompact subsets of L1(μ,X) are examined. For a Banach space X whose dual has the Radon-Nikodym property, it is shown that the weakly precompact subsets of L1(μ,X) are exactly the uniformly integrable subsets of L1(μ,X). Furthermore, it is shown that this characterization does not hold in Banach spaces X for which X* does not have the weak Radon-Nikodym property.

The Effects of Cognitive Style and Socialization Background on Patterns of Behavior: Integrating Individual Differences (Using the MBTI) with Meadian Socialization Theory

Description: The general purpose of this study is to examine the effects of socialization background and cognitive style on individuals' patterns of behavior. The more specific purpose is to integrate the individual differences factor using the Myers-Briggs Type Indicator with Meadian Theory of Socialization in order to explore the ways in which a group of incarcerated individuals with prior felony and misdemeanor convictions and a group of college students are different regarding their different socialization background and cognitive styles. Data for this study were collected from a university and a county jail in Texas. During the process of data collection, two questionnaires consisting of 117 items were used to measure individual characteristics and elements of socialization background. This study is organized into four different chapters. Chapter I involves a detailed review of related literature, the purpose of the study, stated hypotheses, significance of the study, and limitations. Chapter II discusses methodological procedures and Chapter III presents the findings of the study. The last chapter includes a detailed conclusion and practical implications of the study. The findings in this study indicated that the group of incarcerated individuals and the group of college students are significantly different in terms of their different individual characteristics and socialization backgrounds. However, it was found that socialization background has the most significant effects on patterns of behavior among the two groups under study. It was concluded that while accepting the crucial importance of socialization factors, specific psychological characteristics of people also need to be integrated into sociological studies concerning human behavior for the better understanding of different groups and individuals in society.

Professional Commitment, Organizational Commitment, and Organizational-Professional Conflict in the Internal Audit Function Model: Development and Test

Description: This dissertation is a descriptive, exploratory examination of professional commitment, organizational commitment, and conflict between those commitments in the internal audit profession. That conflict has been suggested in prior studies as the source of dysfunctional outcomes such as increased role stress, high turnover, decreased job satisfaction, and the exercise of improper judgment leading to audit failures. The descriptive aspect of this study deals with the development of a more comprehensive structural model of the factors and relationships involved in commitment and conflict than has been developed by previous research dealing with accountants. The exploratory aspect deals with the testing and refinement of the developed model utilizing the internal audit profession as the field of examination. The model developed in this study is derived from the synthesis of factors suggested by role theory, the concept of side bets, the cosmopolitan-local construct, and the concept of commitment as a process. This research utilizes a questionnaire administered to 205 practicing internal auditors in order to test 30 hypothesized relationships. Path analysis is used to determine the significant direct relationships between variables with a process of theory trimming being conducted in order to produce more parsimonious structural models. Indirect relationships between significant variables are identified and their redundant or suppressive nature determined. Explanations of these suppressive or redundant relationships are provided based on the theoretical considerations identified above. Such a determination and explanation of the redundant and suppressive indirect relationships involved in the commitment-conflict relationship has not been accomplished in earlier studies of the subject. Although the procedures used here do not support causal conclusions, the findings of this study indirectly provide evidence that conflict between the two commitments in the internal audit area is not to be considered inherent. The findings also suggest a possible undesirable relationship between organizational formalization and professional commitment.

Determinants of Small Firm Performance: the Importance of Selected Managerial Personality Traits, Perceived Environmental Uncertainty, Scanning Activities, and Managerial Goal Setting Activities

Description: Much of the previous research on organizational performance deals with the larger businesses. As such, the owner/managers of small firms and researchers interested in small businesses have had to work with planning models which were not formulated with small businesses in mind. Therefore, the general purpose of this study is to help correct this deficiency and add to the body of knowledge concerning the contributions specific factors make toward increasing the performance of small firms. Specifically, selected managerial personality traits, managerial perceived environmental uncertainty, managerial scanning habits, and managerial goal setting activities are utilized to develop three models. The three models are used to determine the relationship the factors have to each other and the contribution the variables make toward the performance of the firm. The firms included in this study are located in a South Central metropolitan area. The firms have between 2 and 100 employees, sales of less than 3 million dollars, and have been in operation 2 years or longer. This study utilizes regression analysis and path analysis to determine the effects the factors have on each other and their contribution to the firm's performance. The Statistical Package for the Social Sciences (SPSSx) is utilized to run the regression analysis. An Analysis of Linear Structural Relationships by the Method of Maximum Likelihood (LISREL) is utilized for the path analysis. Using path analysis, the third model demonstrates a total coefficient of determination for structural equations of 0.09. However, only two of the four factors have a t value of 2.0 or greater. The study also indicates the personality trait of dogmatism is inversely related to managerial scanning -.349 p <.01. Perceived environmental uncertainty is negatively correlated to performance at -.215 p <.05. None of the remaining factors demonstrated significant relationship to the firm's performance.

Pre-Impoundment Estimations of Nutrient Loading to Ray Roberts Lake and Prediction of Post-Inundation Trophic Status

Description: Excessive nutrient loading of natural and artificial lakes has led, in some systems, to plethoric algal and aquatic macrophyte growth which can result in aesthetic degradation and undesirable tastes and odors. It would be advantageous to have some indication of the potential trophic status of a reservoir before it is filled. An objective of this study was to assess the water quality and nutrient loading potential of the tributaries entering Ray Roberts Lake, a large reservoir located in north central Texas. Samples from a maximum of thirteen sites were collected on the Elm Fork, Trinity River, Isle duBois Creek, and five additional tributaries. Data were also collected during six storms, from atmospheric deposition collectors, and from soil-water microcosms. The relationship between watershed landuse and mean water nutrient concentrations was evaluated. Significant differences will exist between the two major arms of Ray Roberts Lake: Elm Fork, Trinity River and Isle duBois Creek. While the majority of the annual phosphorus and nitrogen load entering both tributaries is coming from overland flow, the proportion is higher in Isle duBois Creek. Point sources in the Elm Fork contribute a larger percentage of the bioavailable phosphorus, which is significantly greater than in Isle duBois Creek. The water quality of Isle duBois Creek, especially nitrogen, is affected to a greater degree by the landuses in its watershed. Predictive regression models made accurate estimations of stream nutrient concentrations in Isle duBois Creek. The entire reservoir, upon reaching equilibrium conditions, will be classified as a eutrophic lake. The Trinity arm, with a higher phosphorus load, will display a higher trophic status. The Isle duBois arm has a lower phosphorus load which will give it a lower trophic status. The long hydraulic residence time of the two arms of the reservoir will remove nutrients upstream of the main body, ...

Microwave Spectra of ¹³C Isotopic Species of Methyl Cyanide in the Ground, v₈=1 and v₈=2 Vibrational States

Description: The problem of the quadrupole interaction occurring in a vibrating-rotating C₃v symmetric top molecule has been studied in detail. The quadrupole interaction has been treated as another perturbation term to a general frequency expression accounting for the vibrating-rotating interaction of the molecule so that a complete frequency formula is obtained for both interactions, and from which hyperfine spectral components are predicted and measured. The hyperfine transitions in the ground, and v₈=1 and v₈=2 excited vibrational states of the ¹³C isotopes of methyl cyanide have been investigated in the frequency range 17-72 GHz, primarily in the low J transitions (0≤J≤3). The study of the ground state of isotope i3CH3i3CN, and the v₈=1, v₈=2 excited vibrational states for all the isotopes have been conducted here for the first time. A substantial perturbation has been discovered and discussed at the ΔJ=3→4 transitions within the Kl=1 sets in the v₈=1 mode for isotopes ¹³CH₃CN and CH₃¹³CN. A total of 716 hyperfine transitions have been assigned from measurements, only 7 of which have been measured previously. A total of 84 molecular constants have been reported; 70 of these constants are derived for the first time from microwave data.

Strategic Human Resources Planning in American Industrial and Service Companies

Description: This study investigated the current practices of strategic human resources planning (SHRP) at large industrial and service companies in the United States and compared these practices with Walker's Four Stages of Human Resources planning model. The data for this study were collected from 130 industrial companies and 117 service companies listed in Fortune directories of the largest 500 industrial and largest 500 service companies in the United States. The study investigated also the impact of internal and external environmental factors on these companies' practices of SHRP. MANOVA, Factor Analysis, and Percentile Analysis were used as prime statistical methods in this study. Environmental factors studied were found to explain 78 per cent of the variances among large American companies. No significant difference was found between industrial and service companies in their SHRP practices. Significant improvements have taken place in large United States business corporations' practices of SHRP since the introduction of Walker's model (1974). These improvements took place in human resources information systems, forecasting human resource needs, human resource planning and development, and evaluation of SHRP projects, but the improvements were unbalanced. The improvements in corporate-centered SHRP activities were greater than the improvements in employee-centered SHRP activities. The reasons for unbalanced developments were explained and future directions were predicted. The findings of this study were compared to the findings of many recent studies in SHRP fields and future directions of the developments of SHRP were discussed. The conclusions of this study suggested that United States corporations are in need of balanced development in both employee-centered and corporate-centered SHRP. American companies are in need of advanced models to shape their practice in SHRP fields. Walker's model has been evaluated as the best available model. The study showed that mediumsized companies in the United States will benefit from SHRP and that they are ...

Life Histories Behavior and Space Partitioning in Selected Species of Western North American Plecoptera

Description: Five species of stoneflies (Zapada haysi, Plumiperla diversa, Taenionema pacificum, Isoperla petersoni, Arcynopteryx compacta) from the North Slope and Interior of Alaska were examined for seasonal patterns of emergence of adults and growth of nymphs. Generally growth was retarded during the winter in this region, and all species except I. petersoni completed growth prior to January. The life cycles of six stonefly species (Prostoia besametsa, Triznaka signata, Sweltsa coloradensis. Isoperla fulva, Skwala parallela, Claassenia sabulosa) are described from northern New Mexico. In this region growth was generally less retarded during the winter than in Alaska; P. besametsa completed all nymphal growth during late fall and winter. Drumming behavior of a Colorado population of Pteronarcella badia was described using an evolutionary framework to explain the maintenance of signal variation in this species. Laboratory experiments were used to explore the effect of intraspecific and interspecific interactions on spatial partitioning in P. badia and Claassenia sabulosa. P. badia exhibited clumping and distributed itself as the surface area of substrate in low densities; however, in the presence of C. sabulosa its distribution was random and different from available surface area. A field study was used to examine spatial partitioning by three New Mexico stonefly species (I_. fulva, P. besametsa, T. signata) and to ascertain patterns of microdistribution relating to several abiotic and biotic factors. Generally, there was an interaction of the measured abiotic parameters (current, water temperature, time) with nymphal size. Additionally, void space and sample volume were successfully used to compare biotic densities among leaf and mineral substrates, which were higher in leaf packs than in mineral substrates.

Bulimia: a Phenomenological Approach

Description: This study used a qualitative/phenomenological research methodology to examine the perspective of five bulimic subjects about their lives in order to understand the bulimic individual's point of view and develop a clearer picture of the world of the bulimic. This approach involved three interviews for each of the five subjects totalling 22 1/2 hours. The three interviews dealt with the subjects' past and present experiences and their ideas about the future. The qualitative/phenomenological methodology created an in-depth view of each subject's relationship to the beginning of her bulimia and its subsequent development. During the period when the interviews were being transcribed, patterns and concepts emerged and were examined. Nine categories were developed from this data reflecting some of the characteristics of a bulimic's personality. Six research questions were formulated and then answered by evaluating them in the light of the nine categories as well as data and descriptions from the interviews. No one single category was found to be uniquely dominant, but rather the categories tended to appear in a cluster-like fashion depending on the individual personality of the bulimic. The data of this study revealed a distinction between the personality and the behavior of the bulimic. A form with a Likert-like response was developed by the researcher and given out to 11 raters in order to evaluate the presence or non-presence of the categories in selected passages. On the basis of the findings of this study, with its limited subject pool, certain recommendations are presented for the reader that might perhaps be of some use in understanding bulimia.

An Assessment of Occupational Investigation Courses in Texas in Relationship to Mainstreamed Handicapped Students Served

Description: The purpose of the study was to determine if occupational investigation teachers and vocational administrators held similar or differing attitudes toward the occupational investigation courses in relation to the mainstreamed handicapped students they served. The following conclusions were warranted from the findings of the analyses of the data. Findings derived from multiple T tests indicate that occupational investigation teachers perceive all survey item statements concerning Admission, Review, and Dismissal (ARD) meetings and the content of Individual Education Programs (IEPs) as occurring to a significantly lesser degree than do vocational administrators. There is no significant discrepancy in their perceptions toward the current practices of occupational investigation teacher training, student assessment, classroom accessibility, course content, or special education assistance described in the survey items. The results of the multiple T tests indicate that there are no significant differences between the attitudes and perceptions of occupational investigation teachers and vocational administrators in Texas toward the future of any of the conditions reflected in the survey items. Teachers and administrators agree that all of the current conditions reflected by the items should be promoted to a higher degree in the future. The results of the multiple T tests indicate a high degree of significance in the disparity between teachers and administrators with regard to their attitudes toward the amount of change and the degree of improvement in the conditions in the survey item statements reflecting ARD committee meetings and the uses of IEPs. However, no significant disparity was found between their perceptions of the difference between the current practice and the optimum condition for items illustrating teacher training, classroom accessibility, course content, student assessment, or special education assistance.

Relationship among Mosby's Assess Test Scores, Academic Performance, and Demographic Factors and Associate Degree Nursing Graduates' NCLEX Scores

Description: This ex post facto study sought to examine: the efficacy of Mosby's Assess Test as a valid predictor of NCLEX (National Council of State Boards of Nursing Licensure Examination) scores; significant correlations among semester averages, semester tests failed, Nelson Denny Reading Test scores, and NCLEX scores; and differences in NCLEX outcomes in relation to ethnicity, age, and prior practical nursing licensure for 558 associate degree nursing graduates who wrote the NCLEX in 1983 and 1984. Significant positive relationships were found among Mosby scores, Nelson Denny scores, semester averages, and NCLEX scores. A significant negative relationship was found between number of semester tests failed and NCLEX scores. The mean NCLEX score of older graduates was higher than the mean NCLEX score of younger graduates. LPN graduates had a higher mean NCLEX score than non-LPN graduates. White graduates' mean NCLEX score was greater than the average score for black graduates. Combined predictor variables which yielded the best estimate of the criterion variable (NCLEX scores) for all graduates included mean semester average, Mosby scores, age above thirty-three, and Nelson Denny scores, respectively. The most important predictor of black graduates' NCLEX success was prior practical nursing licensure. Other significant predictors for black graduates' NCLEX success were mean semester average, Mosby scores, mean number of semester tests failed, age above thirty-three, and Nelson Denny scores, respectively. Mean semester average, mean score of the Mosby test, mean number of semester tests failed, and age above thirty-three were the most significant predictors of white graduates' NCLEX success. Older graduates had a higher mean Mosby score, a higher mean semester average, and failed fewer semester tests than younger graduates. The study results will be of interest to nurse educators and counselors who are concerned with curricular revision, student counseling, and remediation procedures as these relate to enhancement of ...

Facial Expression Decoding Deficits Among Psychiatric Patients: Attention, Encoding, and Processing

Description: Psychiatric patients, particularly schizophrenics, tend to be less accurate decoders of facial expressions than normals. The involvement of three basic information processing stages in this deficit was investigated: attention; encoding; and processing. Psychiatric inpatients, classified by diagnosis and severity of pathology, and nonpatient controls were administered seven facial cue decoding tasks. Orientation of attention was assessed through rate of diversion of gaze from the stimuli. Encoding was assessed using simple tasks, requiring one contrast of two facial stimuli and selection from two response alternatives. Processing was assessed using a more complex task, requiring several contrasts between stimulus faces and selection from numerous response alternatives. Residualized error scores were used to statistically control for effects of attention on task performance. Processing task performance was evaluated using ANCOVA to control for effects of encoding. Schizophrenics were characterized by generalized information processing deficit while affective disorder subjects evidenced impairment only in attending. Attention impairments in both groups were related to severity of psychopathology. Problems in encoding and processing were related only to a schizophrenic diagnosis. Their decoding deficits appeared attributable to general visuospatial discrimination impairment rather than repression-sensitization defenses or the affective connotation of cues. Adequacy of interpersonal functioning was associated with measures of attending and processing but not encoding. The measures of encoding, however, may have lacked adequate discriminating power due to low difficulty.

An Empirical Study of the Causes of Military Coups and the Consequences of Military Rule in the Third World: 1960-1985

Description: This study analyzed the causes of military coups and the consequences of military rule in the Third World during the 1960-1985 period. Using a coup d" etat score, including both successful and unsuccessful coups, as a dependent variable and collecting data for 109 developing nations from the World Handbook of Political and Social Indicators, The New York Times Index, and public documents, sixteen hypotheses derived from the literature on the causes of military coups were tested by both simple and multiple regression models for the Third World as a whole, as well as for four regions (Sub-Saharan Africa, Asia, Latin America, and the Middle East and North Africa) and in two time periods (1960-1970 and 1971-1985). Similarly, three models of military rule (progressive, Huntington's, and revisionist models) were analyzed to assess the consequences of military rule. The results of the study concerning the causes of military coups suggest four conclusions. First, three independent variables (social mobilization, cultural homogeneity, and dominant ethnic groups in the society) have stabilizing consequences. Second, six independent variables (previous coup experience, social mobilization divided by political institutionalization, length of national independence, economic deterioration, internal war, and military dominance) have destabilizing consequences. Third, multiple regression models for each region are very useful; most models explain more than 50% of the variance in military coups. Fourth, the time period covered is an important factor affecting explanations of the causes of military coups. In the analysis of the consequences of military rule, this study found that military governments did not differ significally from civilian governments in terms of economic, education, health, and social performances. However, the study found that military rule decreased political and civil rights. Its findings are thus very consistent with the best of the literature.

Factors Related to Mississippi School Library Media Centers in Multitype Cooperation

Description: The main purpose of this study was to identify the major obstacles to cooperation as perceived by school library media specialists in the state of Mississippi and to determine if members of the Coastal Mississippi Library Cooperative (CMLC) believe that there are fewer obstacles to cooperation than do non-members. The secondary purpose was to evaluate the CMLC to some extent to determine if success was achieved through organization when defined by the variables, planning, governance, funding, communication, administration, and evaluation. The population of the study was all of the librarians (academic, public, school, and special) in the six-county area which comprises the CMLC, and a random sample of public school librarians throughout the remainder of the state. All of the school librarians were sent a questionnaire that requested their responses to statements of barriers to cooperation. All of the librarians in the CMLC region were sent a questionnaire to obtain their perceptions of participation in the CMLC. Pour librarians, members of the CMLC, were Interviewed to obtain information on the organizational factors of the CMLC. Data received from school library media specialists were submitted to various statistical tests. The Chi-Square statistic was used on the demographic portion of the questionnaire, which revealed that four of the variables and the dependent variable, membership in the CMLC, were significantly different. A t-test performed on the barriers to cooperation section produced no significant differences between the member and non-member responses. The perceptions of participation in the CMLC data revealed that there were differences among the four library systems (academic, public, school, and special) involved, but most of the respondents considered the CMLC to be successful. Data from the interview also revealed that the CMLC was successful in its organization. Due to the overall low response to the survey, the stated hypotheses could not ...
