Resource‐based scholars have focused on the properties of resources and the isolating mechanisms that sustain their rents in the face of competition. Unfortunately, they have devoted far less attention to the sources of vulnerability of many of these resources. We argue that, paradoxically, sources of rent such as isolating mechanisms often have a dark side that renders resources more vulnerable. We highlight three categories of challenges to managing resource vulnerability—protecting them from erosion, coping with their ambiguity, and preserving their required alignment—and identify sources of vulnerability within each. We address these via three primary functions of curatorship: preservation, connoisseurship, and orchestration, respectively. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

The nonparametric approach Data Envelopment Analysis is used in order to measure individual technical inefficiency. Different models are evaluated using a 1991 FADN data set of French pig farms. Organic nitrogen is considered as a byproduct of animal breeding. Used as plant nutrient, organic manure becomes an input in crop production which is pollutant when excessive amounts enter surface and groundwater. In the latter case, the usual hypothesis of strong disposability of organic nitrogen is refuted because the elimination of pollution is costly. In this paper, we introduce a hypothesis of weak disposability of organic nitrogen and compare the technical efficiency measures obtained with and without this assumption. Then, using the duality between the restricted cost function and the input-output distance function and following Färe and Primont (1995), we derive a shadow price of organic nitrogen which can be compared to the unit cost of different existing manure treatments. 相似文献

High-value export-oriented agriculture is today considered as a means of integrating smallholders into the world economy. This paper examines the geographic and organisational changes that have taken place in the fresh pineapple sector over the past 50 years. We begin with a historical analysis of the changes in leadership among producer countries, namely the dethroning of Côte d’Ivoire by Costa Rica. We show that this geographical shift has been accompanied by massive organisational changes: the pineapple sector is increasingly driven by large downstream actors who derive their power from the ability to impose their definition of quality to the whole chain, and from economies of scale and scope. Although varietal innovation plays a key role throughout the period, commercial and logistical innovation are of increasing strategic importance. However, because of the constraints imposed by the concerned supply chains, small farmers risk being excluded or marginalized. 相似文献

Visitor monitoring along roads and hiking trails: How to determine usage levels in tourist sites 总被引:1,自引:0,他引:1
Best-practice visitor-monitoring techniques are crucial for the assessment of tourism-related impacts in natural areas of high conservation value. In such studies, ecosystem variables are typically compared between high and low usage tourist sites. We assessed visitor use at 80 sites in the Flinders Ranges gorges and compared 11 visitor variables for their potential to differentiate usage levels between sites either exposed to vehicle or hiker traffic. We show that the efficiency with which a visitor variable represents usage levels depends on the access mode to gorges, with the number of passing visitors best suited for monitoring of usage levels in gorges permitting hiker access only, and variables describing camping usage best suited for gorges permitting vehicle access.Further, the distinct advantages and disadvantages of four visitor-monitoring techniques were examined; namely, the direct monitoring of visitor use by staff observers, the assessment of proxy variables from which past and present use can be inferred, GPS tracking of visitors and the survey of visitors by an interview-based questionnaire. We recommend GPS tracking because of the reliability and detail of data and the many sites per day that can be sampled. Due to a strong, positive correlation, the campground size and the number of fireplaces may be recorded in proxy of the camper numbers to increase time-efficiency and robustness of measures against short-term fluctuations in usage. Survey data gathered in relation to specific site-use were tempered by the memory of visitors and their ability to describe or reference the visited sites on a map. Visitor surveys were therefore useful only as a supplementary method for differentiating usage levels on a coarser spatial scale. 相似文献

While prior research has extensively studied nutrition labeling use and consumer errors of judgment in the nutrition evaluation process, less attention has been paid to the consumer motivations that simplify the reading of on‐pack nutrition information. To address this gap, this study examines how food consumption goals affect consumer reading of this information. On the basis of a qualitative study, eight food consumption goals have been identified and classified into four types of motivations which impact reading behaviors: “Food Optimization,” “Food Regulation,” “Food Gratification,” and “Food as Mere Necessity.” From this typology, we derive eight on‐pack nutrition information reading heuristics as well as specific inference biases resulting from these simplifying reading strategies. This research also provides guidelines for policymakers so that nutritional messages given to consumers will be more targeted in order to promote better reading of on‐pack nutrition information at the point of sales. 相似文献

The relational approach is often presented as a strategy to retain customers, but it may also be an appropriate approach to encourage customers to complain, as a review of literature shows. Using information contained in complaints and giving the right answers (distributive, procedural and interactional) to such complaints is essential. Relational marketing may also be used to induce customers (but not all of them) to complain about the attributes of certain products/services. This article focuses on these issues and should stimulate further research in this new field. 相似文献

In light of the vertical disintegration of the global aerospace industry, this paper reports on a study that was commissioned by Industry Canada to evaluate whether Canadian aerospace firms have been able to develop the new set of manufacturing and managerial capabilities required to compete in the global aerospace supply chain. A strategic management framework was used to assess the fit between the key success factors of the external environment and the resources and capabilities of the firms studied. The results indicate that although smaller aerospace firms seem to possess technological and engineering skills that are vital strengths in the aerospace industry, better marketing efforts would enable them to enlarge their client base and intensify their participation in the global aerospace supply chain. 相似文献
