This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job‐related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees’ exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization.  相似文献

In a homogeneous‐good duopoly game with a home and a foreign firm, which compete on prices, it has been shown that the optimal way to assist the domestic industry is by a production subsidy. The argument here is that the subsidy is used to keep potential competitive pressure on the foreign firm. This paper analyzes under which conditions this threat of entry of a subsidized home firm is credible. It is shown that in markets where the firms move before the government, a subsidy is not credible and dominated by a tariff in terms of welfare.  相似文献

In applications of expected utility analysis, researchers are confronted with a choice among several utility functional forms. Subjective utility values and probability distributions for price and yield were elicited from Sri Lankan producers of minor export crops. Exponential quadratic and cubic utility functions were estimated. The choice of functional form was found to affect both the classification of risk attitudes and the prediction of harvesting strategy. The exponential function was the best predictor of harvesting strategy because it was the best predictor of mature harvesting. All three functions were equally poor predictors of premature harvesting.  相似文献

Let X (r, n, m, k), 1 r n, denote generalized order statistics based on an absolutely continuous distribution function F. We characterize all distribution functions F for which the following linearity of regression holds E(X(r+l,n,m,k) | X(r,n,m,k))=aX(r,n,m,k)+b.We show that only exponential, Pareto and power distributions satisfy this equation. Using this result one can obtain characterizations of exponential, Pareto and power distributions in terms of sequential order statistics, Pfeifers records and progressive type II censored order statistics.

Customer cocreation during the innovation process has recently been suggested to be a major source for firms' competitive advantage. Hereby, customers actively engage in a firm's innovation process and take over innovation activities traditionally performed by a firm's employees. Despite its suggested importance, previous research has revealed contradictory findings regarding its impact, the nature of involved customers, and the channels of communication that enable cocreation. To provide a more fine‐grained picture, customer cocreated knowledge is first delineated into its key value dimensions of relevance, novelty, and costs, and then their impact on various innovation outcomes is investigated. Next, the study examines the antecedent role of customer determinants; that is, lead user characteristics and customer–firm closeness, on these knowledge value dimensions. Finally, we explore how these effects are moderated by the type of communication channel used. An empirical validation of the conceptual model is performed by means of survey data from 126 customer cocreation projects. The data analysis indicates that customer cocreation is most successful for the creation of highly relevant but moderately novel knowledge. Cocreation with customers who are closely related to the innovating firm results in more highly relevant knowledge at a low cost. Yet, cocreation with lead users produces novel and relevant knowledge. These effects are contingent on the richness and reach of the communication channels enabling cocreation. Overall, the findings shed light on opportunities and limitations of customer cocreation for innovation and reconcile determinants originating in relationship marketing and innovation management. At the same time, managers obtain recommendations for selecting customers and communication channels to enhance the success of their customer cocreation initiatives.  相似文献

Growing dissatisfaction with the prevailing dispersed urban form and its generalized reliance on the automobile has resulted in the formulation of planning models seeking to substitute dispersed development with recentralization. A survey of 301 planning documents with a metropolitan focus, originating from the 58 US and Canadian urban regions with a population exceeding one million, reveals widespread support for urban recentralization. But interviews with 55 planners, involved in the preparation of these plans and/or the implementation of their proposals, highlight actual and foreseen barriers to the implementation of recentralization strategies. The article interprets the popularity of recentralization in planning documents as the outcome of planners' attempts to reconcile their commitment to sustainable development with societal factors affecting planning possibilities. Still, we anticipate serious problems in achieving large‐scale recentralization due to urban development path dependencies emanating from the prevailing urban form and dynamics, institutional structures, and from the limited urban transformative potential afforded by neoliberalism.  相似文献
