The existence of a shared understanding about a collaborative work process among all involved actors is one prerequisite for its successful implementation. The development of a shared understanding is facilitated when the actors make explicit their individual views and create externalizations that can be used as subjects of discourse. Instruments supporting externalization and discourse about collaborative work need to provide adequate forms of representation and guide actors in implementing these reflection and alignment processes. Appropriate guidance can facilitate the construction of a shared understanding for actors not accustomed to such processes. This paper introduces a methodology that offers structural and procedural guidance by adopting diagrammatical conceptual modeling techniques. This methodology has been evaluated extensively in a multiple case study. A combination of interaction analysis of the modeling process and ex-post assessment of the actors’ perceptions has been used to evaluate the adequacy of the proposed methodology with respect to the pursued objectives. The results confirm that the modeling methodology and the proposed guidance measures appropriately support the process of constructing a shared understanding about collaborative work processes.  相似文献

In recent decades, knowledge spillovers have taken the helm as the driving force of growth in cities. The ease of communicating ideas and the sheer density of large urban areas have made this a plausible explanation for continued growth of employment and population in cities. However, there is little consensus on the nature of the optimal conditions for stimulating knowledge spillovers. This paper identifies these optimal conditions by exploring the relative importance of industry specialization, diversity and competition across all industries and all metropolitan areas from 1970 to 2011 in the U.S. Long-term employment growth in cities is found to be driven by industry diversity combined with a high level of competition. This combination fosters the greatest amount of cross-industry fertilization of ideas and knowledge spillovers.  相似文献

This paper investigates the effects of trade finance shocks on real exports by using novel data on two bank-intermediated instruments of trade finance in Korea: foreign trade loans extended by commercial banks and documentary bills purchased by them. Using a vector autoregression (VAR) model, the results show that a negative shock to both instruments adversely affects exports, particularly the exports of small and medium-sized enterprises (SMEs). The trade financing condition explains as much as 10–14 % of the variation in exports, which is comparable to the estimates in previous studies. Noteworthy is that the effects of trade finance on SME exports vary upon whether it is pre- or post-shipment financing.  相似文献

Individual emotions are essential driving forces in strategic decision-making. Nevertheless, the current state of research on emotions and their effects on strategic decision-making is fragmented and inconsistent. Therefore, this paper presents a narrative literature review that aims to bring some structure into current research and to advance an agenda for a future research on emotions in the strategic decision-making context. Based on cognitive appraisal theory and affective events theory this review focuses on organizational and individual antecedents for the development of emotions in the strategic decision-making context as well as on the effects of emotions on the strategic decision-making process. The paper concludes with a conceptual framework that summarizes the findings of this review and indicates possible directions for future research.  相似文献

This study explores social enterprises’ strategies for addressing mission drift. Relying on an inductive comparative case study of two Italian social enterprises, we show how stakeholder engagement combined with social accounting can successfully support a social venture to re-balance its positioning between wealth generation and social value creation. Indeed, stakeholder engagement helps the internal actors of a social enterprise to rationalize and embody pro-social values previously abandoned, while social accounting reinforces this embodiment process by showing the reintroduced social commitment of the social enterprise to external audiences. Conversely, strategies focused only on social accounting and without significant engagement of external stakeholders prove to be unsuccessful in counterbalancing mission drift because they fail to activate the necessary process of internal re-introduction and operationalization of pro-social values and objectives.  相似文献

This paper investigates the effects of institutional changes within the UK housing market in recent decades using structural break tests and time-varying parameter models. This approach is motivated by models of institutional change drawn from the political science literature which focus on the existence of both fast-moving and slow-moving institutional changes and the interactions between them as drivers of the dynamics of asset prices. As a methodological contribution, we use several time-varying parameter models for the first time in investigations of institutional change. Our findings support the existence of both structural breaks and continuous variance in parameters. This contributes to our understanding of the housing market in two respects. Firstly, the dates of structural breaks appear to better match unexpected market shocks rather than remarkable political events, and this supports prior institutional theory. Secondly, assessment of the effect of slow-moving institutional changes shows that people’s biased expectations rather than the economic fundamentals have increasingly played an important role in driving housing prices in the short run although fundamentals continue to drive house prices to converge to their long-run equilibrium.  相似文献
