This article explores the management challenges of emerging new business fields by using a network perspective. We are interested in the extent to which individual firms, by mobilizing cooperative networks of actors, can influence the emergence of radically new business fields. A framework describing the environment and the phases of emergence is proposed. Then the activities within each phase are discussed. Finally, we identify and examine the company-level capabilities involved in the management of these core activities. The study contributes to the management of new business fields.  相似文献

We develop a model that relates self-control to cooperation patterns in social dilemmas, and we test the model in a laboratory public goods experiment. As predicted, we find a robust association between stronger self-control and higher levels of cooperation, and the association is at its strongest when the decision maker’s risk aversion is low and the cooperation levels of others high. We interpret the pattern as evidence for the notion that individuals may experience an impulse to act in self-interest—and that cooperative behavior benefits from self-control. Free-riders differ from other contributor types only in their tendency not to have identified a self-control conflict in the first place.  相似文献

The complexity and advanced nature of modern biotechnology, and its extensive implications for society regarding prosperity, risk and ethics, make a view of the future that is comprehensible and transparent to society desirable. The objective of this feasibility study was to investigate methodologies for strategic planning and regulatory decision-making in technologies involving genetically modified (GM) crops. The planning and regulatory decisions of both the biotechnology industry and public authorities are considered. In the study, knowledge and opinion about a well-defined problem complex are systematically brought together in the consultation of a larger number of stakeholders and experts representing as many major perspectives as possible. On the basis of a test case on the development of a GM-ryegrass, this paper suggests a methodological approach to the uncertainties faced by the biotech industry and public authorities when GM crops are commercialized. The method used was a technology foresight (TF) framework, using a life cycle inventory (LCI) to define the problem complex, a stakeholder panel to identify drivers (of change) that influence the direction of future developments, and weighted stakeholder questionnaires to prioritize these drivers. Once quantified, the weighted stakeholder opinion generated a clear criterion for prioritizing drivers that were judged to be important in the future development of a GM-ryegrass but whose precise impact was uncertain. The four drivers prioritized were: being the first to market the GM-ryegrass, an efficient network on biomolecular know-how, public dialogue and participation in regulation procedures and utility value.  相似文献

Interest rate futures are basic securities and at the same time highly liquid traded objects. Despite this observation, most models of the term structure of interest rate assume forward rates as primary elements. The processes of futures prices are therefore endogenously determined in these models. In addition, in these models hedging strategies are based on forward and/or spot contracts and only to a limited extent on futures contracts. Inspired by the market model approach of forward rates by Miltersen, Sandmann, and Sondermann (J Finance 52(1); 409–430, 1997), the starting point of this paper is a model of futures prices. Using, as the input to the model, the prices of futures on interest related assets new no-arbitrage restrictions on the volatility structure are derived. Moreover, these restrictions turn out to prevent an application of a market model based on futures prices.  相似文献

Aquaculture presents a radically different way of producing fish that aims to transcend the limitations of capture fisheries but that in turn creates new forms of agrarian and ecological transformations. Using the case of Laguna Lake, the paper probes how aquaculture production and corresponding agrarian transformations are inextricably tied to dynamics in capture fisheries in multiple ways. It emphasizes the fundamentally ecological nature of the relations between aquaculture and capture fisheries through a discussion of three interrelated features of agrarian change: commodity widening through the production of a commodity frontier, aquaculture producer strategies of working with materiality of biophysical nature, and the attendant consequences of these processes for agrarian configurations. By examining the appropriation of nature in commodity frontiers and situating relations between aquaculture and capture fisheries as historical‐geographical moments in commodity widening and deepening, the paper highlights the centrality of nature in agrarian change.  相似文献

The objective of this study was to discover potential ways to enhance debriefing so that more can be learned from the experience of extreme events. In order to reach this aim, we explored how personnel in the Explosive Ordnance Disposal team from the Norwegian Armed Forces experienced debriefing after an extreme event. That event was a terror attack on the Norwegian island of Utøya on 22 July, 2011, in which 69 people were killed and 66 were wounded. An Explosive Ordnance Disposal team was sent to the island to search for and disarm potential bombs. We explored how personnel in the team experienced their debriefing after this event. Reports of interviewees' experiences identified two relevant dimensions: content (technical and personal) and form (formal and informal), leading to the development of four categories. The main learning points were that although personnel experienced room to share technical issues during debriefing and hence learn from the situation, there were fewer opportunities to share personal issues, and this seemed to limit the debriefing as a learning process.  相似文献
