The risk of non‐indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways. We tested the hypothesis that increased imports of fresh produce from new sources outside the European Union could increase the risks of non‐indigenous insect pests. We use a bio‐economic model approach in which the number of species arrivals is a function of the volume of imports, whereas the volume of imports itself is a function of gross domestic product, relative import prices and seasonality. The study has identified clear trends, which show import volumes of fresh produce and species detections increasing from new supply sources. If this trend continues in the future, then the UK inspection agency should expect to confront species from new suppliers in much greater numbers, given that import volumes of fresh produce are income elastic.  相似文献

从目前我国的立法实践来看,构建刑事被害人救助体系是十分必要的,在这个体系中,仅靠被害人自助和求助于被告人补偿目前还很不现实,需要首先在补偿对象及条件、补偿金来源、补偿机构的设置、补偿启动机构及方式等方面建立完善的国家补偿制度,同时完善社会援助机制,这是解决目前被害人不利处境的主要途径。此外,还需完善我国的刑事附带民事诉讼制度,使我国的刑事被害人救助制度更加完善。  相似文献

The authors examine the performance impact of formal market information processes. Specifically, a theoretical model is developed that hypothesizes that formal processes for market information acquisition and utilization have direct and positive main effects on new venture success and is then tested using a sample of 222 new ventures located in China. Findings indicate that new venture success is positively correlated with the use of formal processes for market information acquisition and use. Moreover, the relative importance of formal processes to the acquisition and use of market information depends on whether the new venture serves an emerging or established market. In particular, the impact of formal processes for information acquisition is higher among new ventures that serve emerging markets. In contrast, the impact of formal processes for information use is higher among new ventures that serve established markets. We present managerial implications of our results. For example, a new venture with a strong market orientation can respond quickly to emerging marketplace needs, and can even seize the advantage from incumbents. If it is in an emerging market, however, the new venture management team should strive to excel at information acquisition; in an established market, it is important for the management team to excel at information utilization.  相似文献

Summary

An analysis of the property requirements of modern industries such as those in the electronics, pharmaceutical and chemical fields, based on detailed interviewing of over 70 companies, is presented. The factors influencing locational choice are considered, as are the specific features of notional industrial schemes. The key points which emerged from the study include: there is no single type of property suitable for all knowledge‐based companies although generally they can be accommodated in existing premises. Location is the most important factor with relatively little importance attached to the particular building scheme. Locational importance derives largely from the need to be close to a highly skilled labour pool. Close proximity to academic centres is only important to a small number of knowledge‐based companies and is not as significant as has been claimed. Flexibility is important in a variety of ways, in terms of space utilization, expansion capabilities and lease structuring.  相似文献

Under what conditions does a collective strategy exist among organizational members? Where should a scholar look for one? To offer one way to start solving these puzzles I propose a view of organizational strategy as a language game that governs the use of strategy labels at the level of the organization. Organizational strategy exhibits a division of linguistic labour, where responsibility for key concepts is assigned to particular individuals or organizational functions. Such linguistic experts oversee the proper use and maintenance of strategy language. The language‐based view helps to understand linkages between institutional, network, organizational, and micro level views on strategy. It also problematizes widely held intuitions regarding the relationship between strategy and organizational outcomes.  相似文献

Predictive analytics is impacting many diverse areas, ranging from baseball and epidemiology to forecasting and customer relationship management. Manufacturers, retailers, software companies, and consultants are creatively discovering new applications of big data using predictive analytics in supply chain management and logistics. In practice, predictive analytics is generally atheoretical; however, we develop a 2 × 2 model to explain the role of predictive analytics in the theory development process. This 2 × 2 model shows that in our discipline we have traditionally taken one path to theory development, but that predictive analytics can be a salient component of a comprehensive theory development process. The model points to a number of research questions that need to be addressed by our research community. These questions are not just highly relevant to the academic community but also in urgent need of answers to help practitioners execute the right strategies with greater precision and efficiency. We also discuss how one disruptive trend, the maker movement, changes the nature of who the producers are in the supply chain, making big data even more valuable. As we engage in higher levels of dialogue we will be able to make meaningful progress addressing these vital research topics.  相似文献

Abstract

Assessing the economic impact of a tourism event on a host economy often involves the estimation of average event tourist spending per trip/night. As event and destination marketers become more selective with their promotions, targeting prospective high-value tourists, it is important for them to know the spending characteristics of different types of visitors so that resources can be allocated to reach and influence event tourists who will most benefit the host economy. This study's findings of visitors to the 1999 Albuquerque International Balloon Fiesta reveal that tourists from communities nearer the host economy typically spend fewer net dollars than those from greater distances. First time event visitors spend considerably more than repeat visitors who have “been there, done that” and may not feel the need to do “that” again.  相似文献
