Strategic decision-making processes influence firm-level outcomes. Using the theory of upper echelons, this study investigates how diversity in directors’ skills, knowledge, and industry experience influence board decision-making processes that may impact overall strategic decision-making processes. Such diversity has been commonly accepted to be a ‘double-edged sword’—enhancing comprehensiveness but hindering the speed of decision-making. On the contrary, we used an existing large survey database to show that directors’ diverse educational background, functional background, and industry experience (job-related diversity) have a positive effect on comprehensiveness as well as the speed of board decision-making. In addition, our results indicate that board processes (directors’ use of their knowledge and skills) play an important role by transmitting the positive effects of diversity. The study is in a tradition of exploring how boards may influence firms’ strategic decision-making processes. Our findings provide additional arguments for adding job-related diversity to boards of directors.  相似文献

This research focuses on the project structure used by coopetitors to achieve common innovation projects. Scholars have recently identified an original but complex project structure that they call the Coopetitive Project Team (CPT). However, other project structures can also be implemented by coopetitors to achieve innovation. Therefore, we address the following question: for which types of innovation projects is CPT appropriate? We argue that coopetitors need to use CPT for high-risk and high-cost projects when the aim is to develop radical innovation. CPT allows coopetitors not only to develop innovation capabilities through close resource and knowledge sharing but also to manage the risk of opportunism. Conversely, coopetitors should use another project structure, Separated Project Teams (SPTs), for low-cost and low-risk projects when the aim is to develop incremental innovation. The SPT design allows coopetitors both to achieve the goal of the project and to minimize the risk of opportunism. To confirm our assumptions, we studied the project portfolios of Airbus and Thales, two firms in the space satellite industry. Our findings confirm that coopetitors should implement CPTs to handle innovation projects that are costly, risky and highly innovative. CPTs permit the sharing of knowledge and the management of high opportunism risk, both of which are necessary to achieve radical innovation. Conversely, coopetitors rely on SPTs for low-cost projects that require a low degree of knowledge sharing, thus avoiding the risk of opportunism in achieving their incremental innovation objectives.  相似文献

Existing studies with East Asian samples have reported inconsistent findings on the association between parental psychological control and academic performance in children and adolescents. A moderation effect is present, when the magnitude or direction of the association between two variables significantly changes with another variable called a moderator. This study explored moderators for the association between maternal psychological control and academic performance. A total of 338 Chinese secondary school students aged 14–20completed self-report measures of perceived maternal psychological control, academic performance, and attitudes toward filial piety. Structural equation modeling suggested that adolescent age moderated the association of interest: the influence of perceived maternal psychological control on academic performance significantly varied between middle adolescents aged 14–17 and late adolescents aged 18–20. Based on the findings, this study offers a possible rationale for the inconsistent findings in studies with East Asian samples and proposes that parenting effect should be assessed developmentally.  相似文献

In many countries where gambling is legalised, there has been a strong public policy focus on the need for strategies to reduce gambling related harm. These have often included policies requiring staff in gambling venues to identify and/or assist people who might be experiencing gambling-related harm. To facilitate this process, researchers have developed visible behavioural indicators that might be used to profile potentially problematic gambling. Few of these studies have, however, examined whether such indicators or ‘warning signs’ might differ between men and women. In this study, we describe the results of an analysis of data drawn from 1185 fortnightly gamblers that included 338 problem gamblers as classified by the Problem Gambling Severity Index. Indicators of problem gambling were similar between males and females with a few key exceptions. Indicators reflecting emotional distress were more commonly reported by females with gambling problems, whereas problem gambling males were more likely to display aggressive behaviour towards gambling devices and others in the venue. Amongst males, signs of emotional distress as well as attempts to conceal their presence in venues from others most strongly differentiated between problem and non-problem gamblers. Amongst females, signs of anger, a decline in grooming and those attempts to access credit were the most distinguishing indicators. These findings have implications for the refinement of identification policies and practices.  相似文献

National policy initiatives to encourage entrepreneurial behaviour are often developed with limited knowledge of the contextual constraints and causal factors. In this paper, we adopt a social realist approach, generally associated with critical realism, as a framework for analysing levels of entrepreneurial behaviour. The trigger for our study is the apparent anomaly of low levels of German entrepreneurship. We apply the morphogenetic framework of the sociologist Margaret Archer to Germany and then compare this to the United States. We conclude that particular so-called situational logics at the intersection of structure and culture constitute mechanisms which provide strategic direction for the decisions of potential entrepreneurs. We argue that a social realist stance based upon Archer’s sociology provides a practical grounding for research and policy development.  相似文献

Despite the tremendous research studying the factors that influence employees’ well-being, the effect of what happens when leisure time is spent with colleagues remains yet unexamined. Building on the Conversation of Resource Theory, we propose that leisure time spent with colleagues could be understood as a resource, especially for those individuals who have few friends at their workplace. In a cross-sectional design, 136 university employees provided information about the number of friends they have at work, the amount of leisure time spent with befriended colleagues, and their life satisfaction. Results suggest that a larger network of friends at work is positively associated with life satisfaction. Furthermore, the effect of the number of friends at work on life satisfaction is moderated by the amount of leisure time spent with befriended colleagues. Employees who have few friends at work report more life satisfaction, if they spend more leisure time with befriended colleagues, whereas such an effect was not found for employees with a large friend network at work. These results are placed into the context of current discussions about work-life-blending.  相似文献

Objectives: To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru. Methods: Following ethnographic mapping of sex work venues, the authors revisited randomly selected venues to survey MSWs, TSWs and their clients. Results: MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs. Conclusion: Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention.  相似文献

ABSTRACT

Lesbian, gay, bisexual, and transgender (LGBT) service members have made profound contributions to the U.S. military despite serving under anti-LGBT military policies. Little is known about their everyday acts of strength and resistance, which is vital information for developing strengths-based services. This article utilizes a queer theory framework to (a) discuss LGBT military contributions and anti-LGBT military policies, (b) explore three LGBT-specific military minority stressors, and (c) identify four strategies of strength and resistance used to manage an anti-LGBT military environment. Clinical suggestions are proposed for integrating military and LGBT identities and designing interventions that blend military and LGBT cultures.  相似文献
