Previous foot‐and‐mouth disease (FMD) outbreaks and simulation‐based analyses suggest substantial payoffs from detecting an incursion early. However, no economic measures for early detection have been analysed in an optimising framework. We investigate the use of bulk milk testing (BMT) for active surveillance against an FMD incursion in Australia. We find that BMT can be justified, but only when the FMD entry probability is sufficiently high or the cost of BMT is low. However, BMT is well suited for post‐outbreak surveillance, to shorten the length of time and size of an epidemic and to facilitate an earlier return to market.  相似文献

During many manmade and natural crises such as terrorist threats, floods, hazardous chemical and gas leaks, emergency personnel need to estimate the time in which people can evacuate from the affected urban area. Knowing an estimated evacuation time for a given crisis, emergency personnel can plan and prepare accordingly with the understanding that the actual evacuation time will take longer. Given the urban area to be evacuated, street widths exiting the area's perimeter, the area's population density, average vehicle occupancy, transport mode share and crawl speed, an estimation of traffic evacuation time can be derived. Peak-hour traffic data collected at three, midblock, Mumbai sites of varying geometric features and traffic composition were used in calibrating a model that estimates peak-hour traffic flow rates. Model validation revealed a correlation coefficient of +0.98 between observed and predicted peak-hour flow rates. A methodology is developed that estimates traffic evacuation time using the model.  相似文献

During the past decade, a number of interactive technologies, including the Internet, have fundamentally transformed how retailers compete in the marketplace. In a similar vein, emerging interactive technologies can be expected to significantly alter the retailing landscape through their impact on retailing strategy and operations. Furthermore, it is conceivable that certain emerging interactive technologies will be perceived by some retailers as enablers (tools to more effectively compete in the marketplace) and by other retailers as disruptors of the present ways of doing business. Interactive technologies can either be generic, a technology that is readily available from an information technology (IT) vendor and is widely adopted by retailers, or proprietary. An interactive technology that is proprietary can enable a firm to generate economic rents from the innovation for an extended duration of time. Investing in a generic interactive technology, however, may be perceived as a cost of doing business for a retailer, and not a potential source of sustainable competitive advantage. However, a retailer's complementary resource endowments may enable the retailer to more effectively leverage a generic technology relative to its competitors and thereby achieve a sustainable competitive advantage. In this paper, we review the related literature, develop a process model delineating the mechanisms by which an interactive technology can affect and necessitate changes in retailers' strategies and identify directions for future research.  相似文献

We generalize Merton’s asset valuation approach to systems of multiple financial firms where cross‐ownership of equities and liabilities is present. The liabilities, which may include debts and derivatives, can be of differing seniority. We derive equations for the prices of equities and recovery claims under no‐arbitrage. An existence result and a uniqueness result are proven. Examples and an algorithm for the simultaneous calculation of all no‐arbitrage prices are provided. A result on capital structure irrelevance for groups of firms regarding externally held claims is discussed, as well as financial leverage and systemic risk caused by cross‐ownership.  相似文献

Custom-built     
Mass customization has rapidly moved from an abstract theory to a practical source of competitive advantage. Fabrizio Salvador has been studying the companies that have bolstered their business by tapping into the idiosyncratic needs of customers. Tom Brown reports on his latest thinking.  相似文献

This paper is based on research carried out in an EU Framework project, concerning the better integration of mobility management (MM) with land use planning. The objective of the paper is to analyse how, and how far, policies in this field of action can transfer from one member state to another, and to compare this to the theory of policy transfer put forward by Dolowitz and Marsh (2000), using their theory as an analytical framework, but also informing that theory. After providing a definition of this form of integration, the paper explains how far MM and land use planning are currently integrated in the EU member and other states covered in the research (Sweden, Germany, Spain, Lithuania, Poland, Slovenia, Switzerland, the UK, as well as Ireland and the Netherlands). It then presents the results of planning simulation workshops in five of these countries, where a group of planning professionals from each state considered real development sites and how MM could be integrated with the development. It shows that there is scope for transfer but concludes that barriers such as language, differing planning traditions, and the problem of transferring a new policy idea within a country will limit the scope of policy transfer significantly. Nonetheless, it sees a role for EU projects of this nature in encouraging initial consideration of new policy ideas.  相似文献

Although business ethics has a long history as a core theme within the realm of strategic management it has not received considerable attention in top strategy journals until recently. In this paper, we assess the state of business ethics research published over a 5-year period (2006–2010) in Strategic Management Journal to ascertain whether there has been an increase in business ethics research published in the top strategy outlet. The results of our content analysis reveal that ethics research in SMJ is indeed on the rise yet this research stream is still underrepresented with only 5.8 % of all articles published over the five-year period having an ethics theme. Moreover, the link between Corporate Social Performance and Financial Performance was identified as the top theme during the review period.  相似文献
