This article presents findings from the first phase of a research program on the management of long-range planning systems. The initial focus is on behavioral problems encountered by those using planning systems and solutions for dealing with them. Both the problems and solutions were identified by chief planning officers during a university sponsored workshop. Some observations are offered about the way in which managerial thought processes affect the potential for resolving complex behavioral problems in organizations.  相似文献

Turnover turned over: an expanded and positive perspective   总被引:4,自引:0,他引:4  
The negative impact of turnover is well documented in the literature. This paper examines turnover with a unique, positive focus. Turnover is reviewed, not only from the standpoint of the organizational theorist, but with economic, sociological, and psychological/social psychological perspectives. Often ignored benefits of turnover are noted.  相似文献

This paper analyses the effect on the weighted average cost of capital of lags between the times of raising debt and equity finance. It shows the results of such lags when associated with differing levels of gearing and differing costs of debt and equity.  相似文献

The problem of keeping abreast of relevant competitive developments for strategic purposes is common to many organizations. In this article the authors describe a system which they have developed and which is currently in operation which they believe can prove beneficial in meeting this need. They believe that their system provides competitive data in a useful form. Also it ensures that information, and not data, are processed and provided for planners and managers to support their decision-making.  相似文献

Expectancy theory has been criticized for its omission of normative, habitual, and other motivational elements. This paper describes the sources and features of an integrative motivational model from the field of preventive health care that combines expectancy/valence factors with habitual, normative, and conative motivational elements. The model is viewed as having implications for work motivation as well.  相似文献

Abstract

Confidence sets, p values, maximum likelihood estimates, and other results of non-Bayesian statistical methods may be adjusted to favor sampling distributions that are simple compared to others in the parametric family. The adjustments are derived from a prior likelihood function previously used to adjust posterior distributions.  相似文献

Pivotal partings: Forced termination with a sexually abused boy   总被引:1,自引:1,他引:1  
The termination phase of therapy is an integral part of the treatment process engendering its own unique set of dynamics. However, the potential eruption of new material dislodged by the trauma of the impending loss may in some cases require a reassessment of discharge goals and consequent alteration of treatment modality. The likelihood of new material surfacing at this critical juncture is perhaps highest among the caseloads of therapist trainees, wherein the termination date is forced by the time-limited nature of the learning contract. In the following article, supervisor and trainee detail the process of therapeutic shift from a dynamic to a crisis-oriented modality in the case of a young boy whose central trauma emerged during termination.  相似文献

This study explores the determinants of labor supply patterns among Latinas in the USA. We use recent microeconomic data from the Panel Study on Income Dynamics/Latino National Political Survey (PSID-LNPS) to estimate models of labor force participation, wages, and hours worked for a sample of Cuban, Mexican, and Puerto Rican women. We estimate the same models for Anglo and Black women in order to explore ethnic differences in the impact of characteristics affecting both the reservation and the market wage. We find that differences exist in the return to characteristics, such as education, but that there are also substantial differences in the levels of those characteristics across ethnic groups. The low wage rates and labor market activity of Latinas relative to Anglo and Black women are thus likely to be the combined result of lower investments in human capital and larger family size, the greater negative impact of macroeconomic conditions, and a stronger responsiveness to wages. Among Latinas, we find that there are differences in labor market outcomes between national origin and nativity groups. We also find that age at arrival and years in the USA play a role in labor supply, and that this is particularly true for Puerto Rican women.  相似文献

Employer use of employee drugscreening procedures is widespread in the U.S. A state-by-state analysis of statutory law applicable to the drug testing issue is combined with state and industry data to isolate how drug testing laws affect workplace injury rates. Based on our data, injury rates are not statistically related to the state’s legal environment.  相似文献

The 1995 wave of the Add Health study is used to investigate the relative influence of parent gender and residence on patterns of parental involvement with adolescents. Adolescent reports (N =17,330) of shared activities, shared communication, and relationship quality with both biological parents are utilized. A multidimensional scaling analysis reveals that parent gender explains most of the variance in parent‐adolescent involvement, with residential status playing a secondary yet a fundamental role in accounting for these patterns. Resident mothers who do not live with adolescents’ biological fathers engage in the broadest range of activities with their children. Unpartnered resident fathers display patterns of parenting that are as similar to mothers as they are to other fathers.  相似文献
