A laboratory experiment examined the effects of applying decision support system (DSS) technology to decision making in ill-structured problem environments under varying information conditions. Marketing executives participated in the experiment which investigated the effects of DSS availability, DSS training, and data availability on dependent variables that included: (1) the number of alternatives considered by a subject during decision making, (2) the period of time spent by a subject to complete the decision-making process, (3) the subject's perceived confidence in the decisions he or she had made, (4) the amount of data considered by a subject's during decision making, (5) the individual subject's decision processing, and (6) the subject's performance overall. Our results indicate that all three factors significantly affect the number of alternatives considered by subjects during the decision-making process. We therefore suggest that DSS training be coordinated with decision training in order to realize the potential of DSSs as described in the DSS literature. 相似文献

Using data from a survey of union members, we explore how an amalgamation of two Swedish unions affects membership participation.
The research literature on the topic is mostly anecdotal and speculative, suggesting that mergers might have detrimental effects
on membership participation because they create large unions with centralized governance and administration. But in this study,
we do not find a broad-based decline in membership participation measured before and after merger as well as in relation to
a comparison union that did not merge. These results are discussed in terms of the national context of union mergers in Sweden
and the ways that mergers are negotiated, presented, and implemented to preserve membership participation.
An earlier version of this paper was presented at the Third International Conference on Emerging Union Structures: Reshaping
Labour Market Institutions, Canberra, Australia in December 1997. The data collection for this project was supported by funds
from the National Institute for Working Life in Stockholm. 相似文献

This article describes a group‐based intervention for adolescents specifically designed to improve motivation to change sexually abusive behaviour. The intervention is intended to be used as a single module within a comprehensive treatment programme based on cognitive behavioural and relapse prevention principles. It utilizes the Prochaska and DiClemente ( 1983 , 1986 ) model of the stages of change and Morrison's ( 1998 ) seven steps in contemplating change. We have combined these two models to produce ‘11 Steps of Motivation and Action in Changing Sexually Abusive Behaviour’. These 11 steps form the foundation of the intervention. In this paper we describe how we use the 11 steps, with accompanying illustrative vignettes and question cards describing juvenile sexual abusers at various points along the continuum of change, in order to promote the acceptance of responsibility for abusive behaviour and the development of skills to prevent reoffending. Examples of the vignettes are provided, along with a discussion of how they can be used to motivate change, develop healthy group norms in treatment and set individual goals for clients. Finally, we highlight the possibility of future applications of this intervention with male adult abusers, adolescent and adult female abusers, parents groups, significant other groups, individual clients and children with sexually aggressive behaviour.

Abstract Objective: This study examined the prevalence of mental health disorders and their clinical correlates in a university sample of lesbian, gay, bisexual, and queer (LGBQ) students. Participants: College students at a large public university. Methods: An anonymous, voluntary survey was distributed via random e-mail generation to university students during April and May of 2011. LGBQ students were compared with their heterosexual counterparts on psychological and physical status as well as academic performance. Results: LGBQ students reported worse depressive symptoms, higher levels of perceived stress, considered themselves less attractive, and were more likely to be overweight. LGBQ students were significantly more likely to report histories of affective, substance use, and certain anxiety disorders as well as compulsive sexual behavior and compulsive buying. Conclusions: The higher rates of many psychiatric conditions among LGBQ students underscore the need for universities to provide LGBQ students a nonjudgmental environment to discuss sexual orientation and health issues. 相似文献

This paper develops a new class of measures of mobility as an equalizer of longer-term incomes—a concept different from other
notions such as mobility as time-independence, positional movement, share movement, income flux, and directional income movement.
A number of properties are specified leading to a class of indices, one easily-implementable member of which is applied to
data for the USA and France. Using this index, income mobility is found to have equalized longer-term earnings among US men
in the 1970s but not in the 1980s or 1990s. In France, though, income mobility was equalizing throughout, and it has attained
its maximum in the most recent period. 相似文献

This paper examines the effect of country-specific institutional constructs on the relationship between ownership concentration
and performance for firms in the eight Continental European countries of Austria, Belgium, Germany, Spain, France, Italy,
the Netherlands and Portugal. Using data from publicly-traded firms owned by other companies (i.e., blocks), measures of the
quality of investor and creditor protection and the effectiveness of legal institutions are applied. Employing a hierarchical
moderated multiple regression analysis, differential validity is established for the relationship between ownership concentration
and performance as measured by return on shareholders’ funds. This differential effect comes from creditor protection regimes
and is consistent with a relational corporate governance model based on debt finance and concentrated ownership. 相似文献
