The flexible leadership theory explains how top executives and other leaders can influence the financial performance of a business organization. Three key determinants of financial performance are efficiency, adaptation, and human capital. A wide range of leadership behaviors, management programs, structural forms, and external initiatives can be used to influence these performance determinants. Management programs and systems are usually more effective when they are mutually compatible and appropriate for the situation. Effective performance requires a cooperative effort by the multiple leaders in an organization, and they must be flexible and adaptive as the situation changes. The theory provides a way to integrate findings from several different and largely separate literatures. 相似文献

Prior research shows that stock price responds favorably to managerial incentive schemes which lower costs and stimulate growth.
This article analyzes the consequence for shareholders of introducing profit sharing in unionized firms. Positive abnormal
returns were associated with the announcement of collective agreements incorporating risk-sharing components, especially when
the firm was experiencing preexisting financial distress. The realized gains generally exceeded that which could be attributed
to strike activity or negotiated wage reductions. However, there was no indication that profit sharing decreased the perceived
risk of investing in the firm. 相似文献

Drifting into dealing: Becoming a cocaine seller 总被引:1,自引:1,他引:0
This paper describes a study of eight ex-cocaine sellers located via chain referral from eight different levels of sales. To be eligible for the study respondents must have sold cocaine steadily for at least a year and have stopped selling for at least six months. The authors describe modes and levels of entree into cocaine sales, and the subtle transformation of identity that occurs when a person moves from a user to a dealer. The interviews suggest that entry into social worlds of cocaine sales is a fluid process akin to Matza's notion of drift (1964). Five basic ways in which people begin to sell cocaine are identified. The first is to become a go-between, a seller who starts out buying only for friends and only later envisions the profit possibilities. The second mode is to become a stash dealer, a person who sells small amounts in order to better afford their own cocaine use. The third style, the connoisseur, is characterized by the user's desire to buy high quality drugs through wholesale purchases. The fourth mode of entree may be called apprenticeship, trainee-style relationships where the novitiate lives with an established seller, learns the ropes, shares the dope, and eventually takes over all or part of the experienced dealer's business. Finally, there is product line expansion, wherein dealers start outselling other drugs, usually marijuana, and move into cocaine sales when it becomes available.The research reported herein was funded by a grant from the National Institute of Justice (#7-0363-9-CA-IJ)), Bernard A. Gropper, Ph.D., Program Manager, Drugs, Alcohol and Crime Programs, Center for Crime Control Research. The views expressed herein are those of the authors alone. The authors are grateful to the anonymous reviewers ofQualitative Sociology for helpful comments. 相似文献

This research was conducted to determine the prevalence of and variables associated with “burnout” among employees at state residential facilities serving the developmentally disabled. Fourteen heterogeneous facilities from 11 states participated. The sample consisted of 256 top level administrators, 244 direct care professionals, and 224 direct care workers. Subjects from the latter two categories were randomly selected. The results indicated that 15% of the sample were experiencing attitudinal, emotional, and physical exhaustion. Personal variables found to relate significantly to burnout were age, sex, and marital status. Four facility variables showed a significant relationship to burnout: turnover, decision levels, number of directors within the past five years, and fringe benefits. Work related variables showed significant correlations with burnout in 42 of 45 incidences, but none of them were substantial. The findings tend to support the idiosyncratic nature of stress at work which decreases the likelihood of finding a few variables which act as “common causes” of burnout. Results also suggest that the most dedicated, competent, and productive staff members are perhaps the most vulnerable to burnout. 相似文献

Objective. We examine volunteering to support the relief effort after the bombing of the Murrah Federal Building. We address two issues: (1) how widespread was volunteering and what forms did it take, and (2) does Wilson and Musick’s (1997a) “integrated theory of volunteer work” help to explain variation in volunteering in this disaster situation? Methods. We use data from the 1996 Oklahoma City Survey (OKC Survey). The 1996 OKC Survey is based on a random sample of the adult population of Oklahoma City and was administered 10 months after the bombing. Results. Nearly 75 percent of the sample respondents volunteered to support the relief effort in at least one way; giving money and donating nonprofessional goods or services were the two most prevalent volunteer activities. Socioeconomic status, knowing someone killed or injured in the bombing, belonging to voluntary organizations before the bombing, and being affiliated with a religious denomination were predictors of volunteering, depending on the type of volunteer activity considered. Conclusions. The magnitude of volunteering after the Murrah Building bombing was in line with volunteer efforts after other disasters. The integrated theory of volunteer work is a useful framework for studying volunteering after disasters. 相似文献

Summary. We develop Bayesian techniques for modelling the evolution of entire distributions over time and apply them to the distribution of team performance in Major League baseball for the period 1901–2000. Such models offer insight into many key issues (e.g. competitive balance) in a way that regression-based models cannot. The models involve discretizing the distribution and then modelling the evolution of the bins over time through transition probability matrices. We allow for these matrices to vary over time and across teams. We find that, with one exception, the transition probability matrices (and, hence, competitive balance) have been remarkably constant across time and over teams. The one exception is the Yankees, who have outperformed all other teams. 相似文献
