In this article, the authors present a case example of a Chinese American lesbian woman who seeks counseling for career decision making. The client's career issues stem from cultural issues that have created a dichotomy in her life. Using an ecological model, the authors dissect the case, propose interventions, and identify potential problems that may arise. 相似文献

This paper describes the theoretical foundations, empirical findings, and practical and philosophical implications of the Boston Area Diary Study (BADS), a study of the caring behavior of 44 participants over one calendar year. In particular, the paper presents an identification theory of care and discusses how it shaped the conceptualization, collection, and analysis of the data in a year-long diary study of daily voluntary assistance. The findings from the BADS (1) theoretically confirm the identification theory of care; (2) methodologically capture how individuals perceive and carry out caring behavior as a unity; and (3rpar; empirically document the existence of a moral citizenship in America that is substantially more vigorous than is implied by the usual indicators of civic and political citizenship. 相似文献

Ken C. Winters Ph.D. Randy D. Stinchfield Ph.D. Jayne Fulkerson M.A. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1993,9(1):63-84
The development and initial psychometric properties of an adolescent gambling problem severity measure are described. The scale, based on a revision of the South Oaks Gambling Screen (Lesieur & Blume, 1987), was administered to 1,101 older (ages 15 to 18) Minnesota adolescents as part of a state-wide gambling survey. Study results indicated that the scale had moderate internal consistency reliability and was significantly related to alternate measures of problem severity for male subjects. Because the rate and severity of gambling among females was very low, the psychometric adequacy of the scale for females is not known at this time. The implications of study findings to the conceptual understanding of adolescent gambling problem severity as well as study limitations and future research needs, are discussed.Support for the study was provided by the Minnesota Department of Human Services and the Center for Addiction Studies, University of Minnesota, Duluth. The authors gratefully acknowledge the assistance from Robert Blum, Linda Harris, Durand Jacobs, J. Laundergan, Alan Mathiason, Brenda Miller, James Schaefer, school officials from the participating high schools, and interviewers who assisted with the telephone survey. 相似文献

The issue of work place hazards that may threaten the health of an unborn child has long been problematic for women, business decision-makers, and lawmakers. The desire to protect the developing foetus must be balanced against a woman's legal right to get and keep the job of her choice. The issue has never been easy to resolve, as this historical analysis shows. An overview of the potential effects of work place hazards on reproductive health is presented. Relevant fair employment laws are summarized, and a brief history of court cases and employer practices is provided. It is argued that ultimately, foetal protection policies had little or nothing to do with protection of foetuses. They may have had more to do with protecting the employer from potential liability and with perceptions of women's status in the work place than with protecting the next generation. Finally, suggestions for future research are presented. 相似文献

Enabling a Powerful Marine and Offshore Decision-Support Solution Through Bayesian Network Technique 总被引:1,自引:1,他引:0
A powerful practical solution is by far the most desired output when making decisions under the realm of uncertainty on any safety-critical marine or offshore units and their systems. With data and information typically being obtained incrementally, adopting Bayesian network (BN) is shown to realistically deal with the random uncertainties while at the same time making risk assessments easier to build and to check. A well-matched methodology is proposed to formalize the reasoning in which the focal mechanism of inference processing relies on the sound Bayes's rule/theorem that permits the logic. Expanding one or more influencing nodal parameters with decision and utility node(s) also yields an influence diagram (ID). BN and ID feasibility is shown in a marine evacuation scenario and that of authorized vessels to floating, production, storage, and offloading collision, developed via a commercial computer tool. Sensitivity analysis and validation of the produced results are also presented. 相似文献

Testing regression lack of fit without replication: a tutorial around Minitab's XLOF procedures 总被引:1,自引:1,他引:0
A. J. Lawrance 《Journal of applied statistics》1994,21(6):541-548
The tutorial is concerned with two types of test for the general lack of fit of a linear regression model, as found in the Minitab software package, and which do not require replicated observations. They aim to identify non-specified curvature and interaction in predictors, by comparing fits over the predictor region divided into two parts. Minitab's regression subcommand XLOF which gives the tests is only briefly documented in the manual and, unlike virtually all other statistical procedures in the software, it is not standard and cannot be readily found in textbooks. The two types of test are described here; they concern the predictors one-at-a-time and the predictors all-at-once. An example of their use is given. A suite of macros is available which reproduces the results of the XLOF tests in much more detail than is given by the XLOF subcommand. 相似文献

This paper presents an algorithm for the construction of optimal or near optimal change-over designs for arbitrary numbers of treatments, periods and units. Previous research on optimality has been either theoretical or has resulted in limited tabulations of small optimal designs. The algorithm consists of a number of steps:first find an optimal direct treatment effects design, ignoring residual effects, and then optimise this class of designs with respect to residual effects. Poor designs are avoided by judicious application of the (M, S)-optimality criterion, and modifications of it, to appropriate matrices. The performance of the algorithm is illustrated by examples. 相似文献

This study examines the effect of unionization, right-to-work laws, and participation of women in the labor force on income
inequality. Two distinct models are developed using 1970 and 1980 census data on the 50 states in the U.S. First, an income
inequality model is specified as a beta distribution of the second kind to estimate Gini measures of income inequality. Second,
these Gini estimates are used in a simultaneous equations model. The 1970 results indicate that higher unionization rates
decreased inequality while right-to-work laws increased inequality. In 1980, the measure of inequality was lower in states
with higher female labor force participation.
We thank an unknown referee and the editor for comments and criticisms that greatly improved the paper. The usual caveat applies. 相似文献

Sources of drug information among adolescent students 总被引:1,自引:0,他引:1
E Mirzaee P M Kingery B E Pruitt G Heuberger R S Hurley 《Journal of drug education》1991,21(2):95-106
A sample of 1023 eighth and tenth grade students in small to medium-sized central Texas school districts was assessed to determine the amount of information they receive from ten sources about six categories of drugs. The amount of information males reported receiving about each drug category was significantly greater than what females reported, and the amount of information that eighth graders reported receiving about each drug category was significantly greater than what tenth graders reported. Television was the primary source of drug information for all categories of drugs except inhalants, for which friends and television were equally important sources. Parents and printed media (magazines or newspapers) were of secondary importance, followed by friends and teachers. Adolescents were less likely to receive drug-related information from experience, siblings, church, doctors, and police. The reliance on the mass media for drug information in smaller school districts is a pattern which has been previously observed in larger urban districts. This consistency suggests that mass media approaches to drug education are likely to be as effective in rural areas and smaller towns as they are among urban adolescents. Implications for television programming are discussed. 相似文献
