Characteristics of Development Directors in Charitable Homes for the Aged
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. …

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

Kinetic and Chemical Mechanism of Pyrophosphate-Dependent Phosphofructokinase
Data obtained from isotope exchange at equilibrium, exchange of inorganic phosphate against forward reaction flux, and positional isotope exchange of 18O from the (βγ-bridge position of pyrophosphate to a (β-nonbridge position all indicate that the pyrophosphate-dependent phosphofructokinase from Propionibacterium freudenreichii has a rapid equilibrium random kinetic mechanism. All exchange reactions are strongly inhibited at high concentrations of the fructose 6-phosphate/Pi and MgPPi/Pi substrate-product pairs and weakly inhibited at high concentrations of the MgPPi/fructose 1,6-bisphosphate pair suggesting three dead-end complexes, E:F6P:Pi, E:MgPPi:Pi, and E:FBP:MgPPi. Neither back-exchange by [32p] nor positional isotope exchange of 18O-bridge-labeled pyrophosphate was observed under any conditions, suggesting that either the chemical interconversion step or a step prior to it limits the overall rate of the reaction. Reduction of the pyridoxal 5'-phosphate-inactivated enzyme with NaB[3H]4 indicates that about 7 lysines are modified in free enzyme and fructose 1,6-bisphosphate protects 2 of these from modification. The pH dependence of the enzyme-reactant dissociation constants suggests that the phosphates of fructose 6-phosphate, fructose 1,6-bisphosphate, inorganic phosphate, and Mg-pyrophosphate must be completely ionized and that lysines are present in the vicinity of the 1- and 6-phosphates of the sugar phosphate and bisphosphates probably directly coordinated to these phosphates. The pH dependence of …

Perceptions of Decision-Makers of the Future Role of the Texas Higher Education Coordinating Board in the Funding Process for Public Senior Colleges and Universities
This study compares the perceptions of presidents and academic and fiscal vice presidents of Texas public senior colleges and universities and with those of (appointed) members of the Texas Coordinating Board. A survey instrument was developed, based upon appropriate coordinating board functions discussed in the literature review, A five-point scale was used to measure intensity or agreement or disagreement. Responses were subjected to one way analysis of variance to determine differences between administrators and board members. Differences significant at the .05 level are reported. Administrators and board members differed significantly on all statements related to centralized control versus internal autonomy. Board members endorsed a greater variety of roles and a higher level of activity for the board than did administrators, although members were not expansionistic. Administrators indicated diverse opinions regarding the board's role. Responses related to formula funding were similar. Board members believed that requests to the legislature for higher education funding needs should be presented in terms of a statewide system; administrators indicated uncertainty. Both agreed on the increasing importance of long-range planning in formula development, but administrators were unsure whether such planning would help provide stability and realistic expectations in funding. Both groups endorsed a greater role for …

Appraiser Accuracy Utilizing the Texas Teacher Appraisal System: A Demographic Analysis
The purpose of this study was to determine if there are personal and demographic characteristics which can predict the most accurate teacher appraisers. The demographics were limited to the following: campus-level job assignment, employing district size, sex, race, number of years of experience as an administrator, previous level of teaching experience, and curriculum area taught by the appraiser. The 622 subjects were school administrators trained to utilize the Texas Teacher Appraisal System. The data were analyzed using multiple linear regression. Where an independent variable was significant (.05), a follow-up ANOVA and Tukey's multiple comparison were employed. Based on the findings of this study the following conclusions were drawn: 1. A summary data set indicated there was little evidence that any of the demographic variables was a significant predictor of accuracy in the evaluation process. 2. Six different data sets indicated that varying instructional settings and methodologies can influence evaluator accuracy. The campus assignment, years of experience, content area taught, race, and sex of the appraisers were all identified in at least one of the exercise sets as having significance. Except for sex and race, none of the variables was found to be significant when the overall prediction equation with all …

A Study to Determine the Relationship of Versatile Behavior to Individual Demographics, Job Characteristics, Organizational Climate Performance Feedback and Job Satisfaction
The behavioral characteristics of leaders have been subjects of study for centuries. The scope of these studies has grown to encompass task analysis, follower needs and situational requirements. Current leadership theories consistently recognize the need for a successful leader to adjust behavior to meet the needs of the task, followers and situation. The problem of this research is to define this ability to modify one's behavior, measure it and test its relationship to demographic and job characteristics. The purpose of this study is to evaluate the correlation of individuals" ability to modify their behavior to job function, hierarchy, climate, feedback, satisfaction and their demographic characteristics. The hypotheses held that high ability to modify behavior would correlate positively with job characteristics, climate, feedback and satisfaction and show no correlation to individual demographics. Data were collected through the administration of three research instruments to 138 managers of three business firms. The instruments were the Participant Data Form providing job and demographic characteristics, Descriptive Adjective Questionnaire measuring an individual ability to modify behavior, and Climate and Satisfaction Evaluation Index measuring climate, feedback and satisfaction. Perason's correlation coefficients were calculated to identify possible relationship between the manager's ability to modify behavior, called versatility, and …

Personality and Behavioral Correlates of Autonomic Imbalance
Individual differences in autonomic nervous system responsiveness have been linked to a variety of physical disorders and personality and behavioral tendencies. The present study attempted to correlate specific personality characteristics hypothesized to be associated with either sympathetic or parasympathetic dominance based on the work of M. A. Wenger. The Clinical Analysis Questionnaire Personality Inventory, a physical disorders questionnaire, a self-report stress measure, and seven psychophysiologic tests were administered to 60 undergraduate students in an introductory psychology class at North Texas State University. The results provided limited support for the hypotheses. A skewed population with 50 of the 60 subjects achieving scores indicative of sympathetic dominance occurred. Statistical comparison (t-tests) of the CAQ personality traits, and clinical factor scores of these 50 subjects labeled sympathetic dominant with CAQ norms for college students revealed means on five personality traits and three clinical factors were significantly different for the sympathetic dominant group at the .05 or greater level of significance. These findings were interpreted as limited support for Wenger's work and for the positions of Acker and Kagan that individuals with more reactive sympathetic nervous systems tend to have difficulty binding anxiety, poor emotional controls and outlets, ambivalence about interpersonal relationships, and a …

The Determinants of Off-Balance-Sheet Hedging in the Value-Maximizing Firm: an Empirical Analysis
The observed use (and indeed tremendous growth in volume) of forward contracts, futures, options, and swaps as hedges against interest rate risk, foreign exchange risk, and commodity price risk indicates that hedging does add value to the firm. The purpose this research was to empirically examine the value of off-balance-sheet hedging. The benefits of off-balance-sheet hedging were found to accrue from reducing (1) taxes, (2) expected financial distress costs, and (3) agency costs. Taxes. Hedging reduces the firm's tax liability by reducing the variability in taxable income. The value of hedging to the firm is a positive function of the convexity of the tax function and the variability of taxable income. Expected Financial Distress Costs. The value of hedging is a positive function of the degree to which hedging reduces the probability of financial distress and the costs of financial distress. Agency Cost. Due to the fact that bondholders and some managers hold fixed claims while shareholders hold variable claims, shareholders desire more risky projects than do bondholders or managers. Hedging reduces this conflict by allowing shareholders to undertake higher risk projects while protecting the holders of fixed claims. Firms can achieve the same benefits of hedging by using alternative …

A Tagmemic Analysis of Coherence in the Writing of Descriptive Texts by College Students
For this study an attempt was made to bridge the disciplines of linguistics and composition in order to examine factors contributing to textual coherence. Pairs of descriptive texts written by fifty college students were examined in order to identify the factors which differentiate quality and topic. Students were asked to compose a descriptive paragraph on the topic of fall. They were then encouraged to use their five senses, given leaves, and asked to compose a paragraph describing the leaves. The pairs of texts thus elicited were evaluated for preference by readers. The ANOVA revealed a significant difference (p=.001) between the two topics with fall texts preferred over the more specific leaves texts. Results suggest that encouraging students to use their five senses does not improve their writing. It may be more important to move through various levels of abstraction than to merely focus on sensory detail. The texts were also scored holistically by two trained evaluators. Results of this grading were used to choose five high- and five low-coherence texts on each of the two topics. These 20 texts were then analyzed in terms of the tagmemic referential hierarchy. A MANOVA was done to examine the dependent variables of Slot …

The Characteristics and Properties of the Threshold and Squared-Error Criterion-Referenced Agreement Indices
Educators who use criterion-referenced measurement to ascertain the current level of performance of an examinee in order that the examinee may be classified as either a master or a nonmaster need to know the accuracy and consistency of their decisions regarding assignment of mastery states. This study examined the sampling distribution characteristics of two reliability indices that use the squared-error agreement function: Livingston's k^2(X,Tx) and Brennan and Kane's M(C). The sampling distribution characteristics of five indices that use the threshold agreement function were also examined: Subkoviak's Pc. Huynh's p and k. and Swaminathan's p and k. These seven methods of calculating reliability were also compared under varying conditions of sample size, test length, and criterion or cutoff score. Computer-generated data provided randomly parallel test forms for N = 2000 cases. From this, 1000 samples were drawn, with replacement, and each of the seven reliability indices was calculated. Descriptive statistics were collected for each sample set and examined for distribution characteristics. In addition, the mean value for each index was compared to the population parameter value of consistent mastery/nonmastery classifications. The results indicated that the sampling distribution characteristics of all seven reliability indices approach normal characteristics with increased sample size. The …

Government and Private Funding of Nonprofit Visual Arts Organizations in the State of Texas: An Analysis
The problem addressed in this study is the administrative process and criteria used by nonprofit visual arts organizations in the State of Texas in acquiring government and private funding. The purposes of the study were to examine the organization and administrative process of the nonprofit visual arts organization, to determine the criteria utilized by government and private funding sources for distribution of funds to nonprofit visual arts organizations, and to examine the process used by nonprofit visual arts organizations when acquiring funds from government and private sources. The data were obtained by means of a descriptive survey questionnaire which was mailed to 336 selected nonprofit visual arts organizations in the State of Texas. These organizations represent the following six areas of visual art: foundations, galleries, museums, associations, photography, and schools. From these areas the population was further refined to include only museums and associations, which represent the extreme diversity of administrative processes used. The resulting subpopulation was comprised of forty-six organizations which had filed for grants from the Texas Commission on the Arts within the past three years. Thirty research questions were answered from the results of the questionnaire. Research questions one, and three through thirty were analyzed and presented …

History of Counseling Services in Hong Kong
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 …

An Empirical Study on the Use of Promotion in Hospitals
The role of marketing and marketing communication in hospitals has grown in the last decade. The need for hospitals to make careful decisions about their marketing communication efforts is mandated, given the changes taking place in the hospital industry. The purpose of this dissertation was to conduct empirical research to determine whether for-profit and non-profit hospitals perceive and utilize promotion as a marketing strategy element. The two steps taken included: identifying important factors considered by hospital administrators and marketing staff in the development of communication messages designed for patients, hospital staff and medical staff; and testing the factors developed and studying the attitudes of hospital personnel toward promotion using a national sample of hospitals. In phase 1, focus group interviews were conducted in a surrogate for-profit hospital and a surrogate non-profit hospital. In phase 2, an original mail questionnaire was used to collect data from a sample of 80 hospitals. A total of 38 hospitals participated, providing 114 usable responses. Test statistics included content analysis, Chi-Square, Pearson correlation coefficient and Analysis of Variance. The results of the focus group study indicated the practice of marketing in hospitals is in its early growth stages and marketing is viewed as nothing more …

Client-Therapist Interaction and Perceived Therapeutic Outcome
This study sought to determine the therapeutic effectiveness of client-therapist dyads in a residential treatment center for emotionally disturbed adolescents. The theories of George Kelly's personal construct psychology were utilized in assessing the dyadic relationship. The four elements investigated were organizational similarity, understanding, organizational congruency and predominant selves. The sample consisted of 140 dyads comprised of 10 adolescent boys and girls and 14 therapeutic staff of a residential treatment center in the southwest United States. Responses to Kelly's Role Construct Repertory Test were compared to four relational factors—parental/respect, identity, problem-solving, and sexual/affection—and two rating scales of client-therapist preference and ratings of therapeutic effectiveness. Contrary to expectations, as content similarity among dyads composed of clients and staff increased, there was not an increase in functional aspects of the therapy relationship. Possible mitigating factors may have been level of client disturbance and/or methodological issues relating to how organizational similarity was determined. Dyadic understanding was not found to be related to perceptions of the therapy relationship. This may be a function of adolescent of adolescent clients' need for independence and resistance to adult understanding and control. Therapy dyads with a moderate level of lateral or vertical organizational congruence were not found to be …

Religious Resurgence and Religious Terrorism: a Study of the Actions of the Shiʹa Sectarian Movements in Lebanon
The purpose for undertaking this case study of the Shi'a in Lebanon is threefold. First, as a hypothesis-generating case study, its objective is to formulate relevant hypotheses about religious resurgence and religious terrorism. This study achieves this objective by formulating 14 general and nine special hypotheses, and testing and confirming the latter. Second, the purpose of this study is also to explore the trajectory of the Lebanese Shi'a's sectarian mobilization. This exploration permits the conceptualization of geocultural immobility and its effect upon a religious minority. It deduces that the Lebanese Shiga's geo-cultural immobility is directly related to their active religious resurgence. The third purpose is to study the changes in the objectives and tactics of a religious minority, that of the Muslim Shi'a in Lebanon. This research is able, via its primary and secondary data, to show a relationship between the Lebanese Shiga's religious resurgence and their use of religious terrorism. This study introduces the concept of geo-cultural immobility. A minority's geo-cultural immobility is identified as an imposed low geographic mobility within a nation with low cultural pluralism. It establishes the Lebanese Shi'a's geo-cultural immobility, to which it attributes their religious resurgence. This Lebanese Shi'a religious resurgence is proven in …

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
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 …

An Empirical Investigation of the Structural Form and Measurement Validity of the Hill Inventory
This research began with the Hill Inventory. Cognitive style preference variables were classified as one of following four types: Theoretical Codes, Qualitative Codes, Social-Cultural Codes or Reasoning Modalities. A consumer behavior perspective was then used to form an alternative structure for the Hill Inventory variables. The following three constructs were proposed: Evaluation Codes, Perceptual Codes, and Reasoning Modalities. The purpose of this research was to assess the structural form and measurement validity of the Hill Inventory. Specific steps taken to accomplish this objective included: developing confirmatory factor and structural equation models; using the LISREL software package to analyze the model specifications; and assessing the validity of the questions used to measure the variables. A descriptive research design was used to compare the model specifications. The research instrument consisted of eight statements for each of twenty-eight variables for a total of 224 questions. Five-point response choices were described by the words: often, sometimes, unsure, rarely, or never. The sample consisted of 285 student subjects in marketing classes at a large university. Data analysis began by comparing the distributions of the data to a normal case. Parameter estimates, root mean square residuals and squared multiple correlations then were obtained using the LISREL …

Play Therapy Behavior of Maladjusted and Adjusted Children
The diagnostic value of children's play was investigated. The question explored was "Can maladjusted children be discriminated from adjusted children through observation of their play therapy behavior?" The play of 15 maladjusted and 15 adjusted children 5 to 10 years of age was compared during an initial 36-minute play therapy session. Three scales of the Play Therapy Observational Instrument (PTOI)—emotional discomfort, social inadequacy, and use of fantasy-- were used to rate the children's play. The children in the maladjusted group were referred by their parents for counseling and their teachers reported the children had exhibited one or more problem behaviors indicative of emotional disturbance. The children in the adjusted group were recommended by their teachers as exhibiting none of the problem behaviors and their parents did not believe their children needed counseling. Discriminant function equations predicted correct group membership for 23 of the 30 children during the second 12-minute time segment and for the entire play session. The analysis showed the play behaviors on the emotional discomfort scale of the PTOI items discriminated maladjusted and adjusted children. During the second and third 12-minute time segments and when all three time segments were combined, maladjusted children's play expressed significantly more dysphoric …

Relationship Adjustment in Marriage as Influenced by Psychological Temperament and Family-of-Origin Socialization Experiences
This research examined the influence of psychological temperament and family-of-origin socialization influences on relationship adjustment in marriage. The major goals were to determine: (a) if there was a relationship between the temperament of one mate in the marriage and the temperament of his or her spouse, and (b) if there was a relationship between the marital adjustment scores of a mate relative to either personal temperament or that of his or her spouse. A secondary purpose was to determine if certain family-of-origin socialization experiences influenced adjustment in marriage. One hundred seventy-nine couples (H = 358) completed three test instruments including the Myers-Briggs Type Indicator (Myers, 1962), Dyadic Adjustment Scale (Spanier, 1976), and the Socialization Background Questionnaire (Church, unpublished), along with a demographic questionnaire. The subjects, volunteers from 12 churches in a large metropolitan area, had mean ages of 35.3 and 33.6 years for husbands and wives, respectively, and had been married for an average of 10.1 years. Five hypotheses and two research questions were tested at the .05 level of significance. The results gathered did not support the hypothesis that there was a relationship between temperament type and mate selection. Similarly, no support was evidenced for any specific relationship between …

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

The Historical Development and Future of the National Technological University
The National Technological University (NTU), a consortium of more than twenty American engineering schools, broadcasts courses produced at member institutions to professional engineers at corporate sites across the country. It is a nonprofit institution.begun in fall 1984 with headquarters in Fort Collins, Colorado, which offers only course work leading to the Master of Science degree in various branches of technology, or applied science. Students must be sponsored by their corporate employers who pay their tuition. This is the first systematic examination of the instructional process at an educational institution created in response to the demands of the governmental and corporate sectors' technological needs. This study includes an attempt to explore the effectiveness of that instructional process and the use of computers in distance education at NTU and implications for institutions of the future. This study focuses on distance education, corporate education, national universities and nontraditional institutions and the extent to which NTO exemplifies each of these concepts. It covers the organizational structure and methods of operation of NTU, and offers opinions of students, faculty, and other personnel associated with the institution as reflected by surveys, interviews, and the media.

Pre-Impoundment Estimations of Nutrient Loading to Ray Roberts Lake and Prediction of Post-Inundation Trophic Status
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 Analysis of Patient Status Following Substance Abuse Treatment and Utilization of Medical Care
Subjects were 2,950 patients who had previously received inpatient treatment for substance abuse at 40 treatment centers in 13 states and were followed up by the Chemical Abuse/Addiction Treatment Outcome Registry (CATOR) via telephone during the 2 years immediately following their treatment. All subjects were contacted every 6 months and asked a series of questions regarding their relapse status, medical utilization, illnesses, injuries, and arrests. Patient status was based on 3 categories: (1) abstinence from any abuse of a chemical, (2) brief relapse of less than 3 months abuse of any chemical, or (3) total relapse of longer than 3 months of any chemical. Findings showed that abstainers had fewer days in the hospital for emotional problems and detoxification. Abstainers also had fewer visits to the hospital for emergency reasons. Males in the brief relapse category had a greater number of injuries than abstainers or total relapsers. Regarding arrests and automobile accidents, no difference was discovered. However, regarding Drunk While Driving (DWI) arrests, abstainers had fewer arrests.

Strategic Human Resources Planning in American Industrial and Service Companies
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 …
