Although there is a growing body of research on social media, only few studies have considered organic products. Therefore, this study mapped the diffusion path of the social media resources for organic products in Mexico and South Korea through Twitter and compared the contents of tweets about organic products in terms of their semantic and hyperlink networks using webometric methods. The results indicate that for organic products, Koreans sent tweets much more frequently than Mexicans. Mexican tweets focused on basic food products in street markets, whereas Korean tweets highlighted promotions and firms, revealing the corporatist structure of its economy. In both cases, the findings support Twitter as a useful tool for Word-of-Mouth Communication on the online environment, among product consumers, and between consumers and enterprises.  相似文献

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

Since the invention of the European Patent System, national patent systems have continued to co-exist, although they did lose appeal. How have the different national systems been affected in view of their characteristics? In order to answer this question a constant-market-share (CMS) analysis is carried out. While on a theoretical level, the different elements adding to the appeal of each patent system are discussed, the CMS-analysis reveals the importance of country size in that the national systems of smaller countries lose.  相似文献

E-commerce is increasingly influencing business operations, as a major supportive medium for different strategies or as a strategy on its own. This paper seeks to identify impacts from concomitant changes on the development of cities. To this purpose, emerging time-based strategies are analysed in manufacturing and customer-services strategies are analysed in the services sector. The focus of the study is on proximity needs and what these needs imply for elimination of physical segments from value chains and insertion of virtual segments into these chains. The findings are then linked with trends for agglomeration or spread of urban activity. The conclusion is that the future of cities is far from clear. Trends for agglomeration go hand in hand with trends for spread on different spatial levels. In addition, there are huge knowledge gaps. The paper concludes with suggestions for further research to fill these gaps.  相似文献

To address agility in public administration, we have developed a knowledge acquisition infrastructure for legal knowledge, based on an implementation‐oriented conceptualization of the legal system. Our objective is to reframe legal knowledge as a knowledge source in a design‐oriented task ontology, building on insights from the CommonKADS methodology for intelligent system design. The main result is to make case law and legal expert knowledge of critical incidents in organizations, two diagnostic knowledge sources underutilized in modern management and engineering, more accessible as a resource for design of agile organizational structures and intelligent systems.

In this article, we define a new construct for urban economic and investment analysis, which revisits the conventional wisdom that investment in real estate development is riskier than investment in stabilized property assets. This new construct, referred as a “development asset value index” (DAVI), is a value index for newly developed properties (only) in a given geographical property market. It tracks longitudinal changes in the highest and best use (HBU) value of locations, and it reveals developer and landowner behavior taking advantage of the optionality inherent in land ownership. In particular, the DAVI reflects developers' use of flexibility in the exercise of the call option to (re)develop the property to any legal use and density. We empirically estimate a DAVI for commercial property (i.e., central locations) and compare it with a corresponding traditional transaction‐price‐based property asset price index (PAPI) corrected for depreciation. We believe that the difference primarily reflects the realized value of flexibility in land development. We find that the DAVIs display greater value growth and are smoother over time and less cyclical than their corresponding PAPIs for the same locations. This suggests that developers successfully use flexibility, and that development may be riskier than stabilized property investment due primarily only to leverage effects (construction costs). Practical implications are also discussed.  相似文献
