The purpose of this case study was to identify the negotiation strategies employed by an epileptic amateur musician engaged in serious leisure to overcome leisure constraints. Data were collected by semi-structured interview, observation and informal interaction. Results revealed that the subject employed various cognitive (i.e. anticipating benefits, weighing pros and cons, immediate resolving, accepting costs and pragmatism about performance) and behavioural (i.e. planning/event management, scaling back participation and communication and cooperation) negotiation strategies. While strategies were employed to overcome constraints, participation was also facilitated by individual beliefs and interpersonal relationships. Results also suggested that negotiation strategies are interconnected, and that perceived stigma did not influence participation in serious leisure.  相似文献

The governance of smart city networks emerges as a new research area intersecting smart governance and public networks studies. This work aims to contribute to the literature on smart cities governance by studying councillor's governance in complex networks and on network performance. To carry out this analysis, the Spanish Network of Smart Cities (RECI), one of the first of its kind and an international reference for city networks, is reviewed as a case study, with the main objective of establishing a theory on its global innovation capacity and operations, together with the local level spurring influenced on its members. A PEST (Political, Economic, Social and Technological) analysis was carried out in order to assess the impact of the smart city network both at local, national and international level. This research was completed with a consultation carried out among some of RECI's municipalities. The analysis of the results shows how RECI can be considered an example of a well organised network with quantifiable savings for its members, capable of configuring future policies in local administration, necessarily related to efficiency, digitalization and citizen-centricity and with key topics to build the future. The study also suggests recommendations oriented to potential improvements that smart city networks could undertake.  相似文献

Research Summary: Research exploring investor reactions to sustainability has substantial empirical limitations, which we address with a large‐scale longitudinal financial event study of the first global sustainability index, DJSI World. We examine investor reactions to firms from 27 countries over 17 years that are added, deleted, or continue on the index. We find that once relevant controls and comparisons to observationally equivalent firms beyond the index are included, DJSI events have only limited significance and/or materiality. Nonetheless, investors' valuation of sustainability around the world has evolved over time, involving diminishing reactions to U.S. firms and increasing benefits, particularly of continuation on the index, over time. The study highlights the importance of careful analysis and longitudinal global samples in making inferences about the financial effects of social performance. Managerial Summary: The debate about how investors perceive corporate social responsibility (CSR) predates Milton Friedman's famous statement that the only social responsibility of business is to increase profits. Although extensive research has studied whether sustainability contributes to financial performance, we have yet to understand whether investors believe it pays off. This financial event study of reactions to the addition, continuation, and deletion from DJSI World, the first global sustainability index, shows that investors care little about DJSI announcements. Nonetheless, there is some evidence that global assessments of sustainability are converging and that investors may increasingly be valuing continuation on the DJSI, suggesting that firms may gain at least limited benefits from reliable sustainability activities.  相似文献

Do shareholders gain when managers disperse corporate resources through activities classified as corporate social responsibility (CSR)? Strategy scholars have recently developed a theoretical model that links such activities to shareholder value when a firm suffers a negative event; we test key portions of this theory of the ‘insurance‐like’ property of CSR activity. We posit that such activity leads to positive attributions from stakeholders, who then temper their negative judgments and sanctions toward firms because of this goodwill. We extend the risk management model by theorizing that some types of CSR activities will be more likely to create goodwill and offer insurance‐like protection than other types. We delineate several firm and event specific characteristics that we expect to influence the link between CSR activities and an insurance effect. We then test our model using an event study of 178 negative legal/regulatory actions against firms throughout the 11 years from 1993–2003. We find that participation in institutional CSR activities—those aimed at a firm's secondary stakeholders or society at large—provides an ‘insurance‐like’ benefit, while participation in technical CSRs—those activities targeting a firm's trading partners—yields no such benefits. We conclude by considering the implications of our findings for future theorizing and research into the economic value of CSR engagement. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献
