Information professionals performing business activity related investigative analysis must routinely associate data from a diverse range of Web based general-interest business and financial information sources. XBRL has become an integral part of the financial data landscape. At the same time, Open Data initiatives have contributed relevant financial, economic, and business data to the pool of publicly available information on the Web but the use of XBRL in combination with Open Data remains at an early state of realisation. In this paper we argue that Linked Data technology, created for Web scale information integration, can accommodate XBRL data and make it easier to combine it with open datasets. This can provide the foundations for a global data ecosystem of interlinked and interoperable financial and business information with the potential to leverage XBRL beyond its current regulatory and disclosure role. We outline the uses of Linked Data technologies to facilitate XBRL consumption in conjunction with non-XBRL Open Data, report on current activities and highlight remaining challenges in terms of information consolidation faced by both XBRL and Web technologies. 相似文献

This article focuses on the effectiveness of banner advertisements.Drawing from theory on functional versus expressive products and wear in versus wear out it argues that product type and time are important factors in World Wide Web (WWW) advertising. The results from a large empirical study are reported and show that responses to banner advertisements differ between functional and expressive products and over time. Functional product banner advertisements have higher initial click-throughs that quickly deteriorate and they have no effect through advertisement impressions. Expressive products need time to wear in as both click-through rates and positive brand attitudes from advertisement impressions increase with repeated exposures. These differences in consumer response are conceptualized as thinking and feeling on the WWW,thereby providing important implications for advertisers. 相似文献

Biofortified staple foods are currently being developed to reduce problems of micronutrient malnutrition among the poor. This partly involves use of genetic modification. Yet, relatively little is known about consumer acceptance of such second‐generation genetically modified (GM) foods in developing countries. Here, we analyse consumer attitudes towards provitamin A GM cassava in the north‐east of Brazil. Based on stated preference data, mean willingness to pay is estimated at 60–70% above market prices for traditional cassava. This is higher than the results from similar studies in developed countries, which is plausible given that micronutrient malnutrition is more severe in developing countries. GM foods with enhanced nutritive attributes seem to be well received by poor consumers. However, the results also suggest that acceptance would be still higher if provitamin A were introduced to cassava through conventional breeding. Some policy implications are discussed. 相似文献

We consider a model of directed search where the sellers are allowed to post mechanisms with entry fees. Regardless of the number of buyers and sellers, the sellers are able to extract all the surplus of the buyers by introducing entry fees and making price schedules positively sloped in the number of buyers arriving to their shops. This is in contrast to results that are achieved for large markets under the assumption that sellers cannot influence the utility of any particular buyer (market utility assumption), in which case buyers obtain strictly positive rents. If there is a bound on the prices or on the entry fees that can be charged, then the equilibrium with full rent extraction does not exist any more, and the market utility assumption is restored for large markets. 相似文献

If one is interested in managing fraud, one must measure the fraud rate to be able to assess the degree of the problem and the effectiveness of the fraud management technique. This article offers a robust new method for estimating fraud rate, PRIDIT‐FRE (PRIDIT‐based Fraud Rate Estimation), developed based on PRIDIT, an unsupervised fraud detection method to assess individual claim fraud suspiciousness. PRIDIT‐FRE presents the first nonparametric unsupervised estimator of the actual rate of fraud in a population of claims, robust to the bias contained in an audited sample (arising from the quality or individual hubris of an auditor or investigator, or the natural data‐gathering process through claims adjusting). PRIDIT‐FRE exploits the internal consistency of fraud predictors and makes use of a small audited sample or an unaudited sample only. Using two insurance fraud data sets with different characteristics, we illustrate the effectiveness of PRIDIT‐FRE and examine its robustness in varying scenarios. 相似文献

Seasonal employment is important in the service industries. Having motivated and satisfied employees is fundamental when front-line employees play a key role for the customers' perceived service quality. Seasonal work differs from permanent employment in many aspects and if managed properly, this could be a competitive advantage and contribute to the success of an organization. This study focuses on seasonal employees' intention to return and to do more than expected at work as well as the relationships between certain motivational factors and job satisfaction. A survey was carried out at four ski resorts with 477 respondents. Correlation and regression analyses indicate that job satisfaction influences the intention to return but does not have a strong influence on organizational citizenship behaviour (i.e. doing more than expected at work). The results improve our understanding of seasonal workers' motivation and behaviour. The concluding part discusses managerial implications. 相似文献

This paper examines the linkages between US and Latin American stock markets during the 1995–2002 period using recently developed cointegration techniques that allow for structural shifts in the long-run relationship. Results suggest that when conventional cointegration tests are applied, a long-run relationship is found only in the cases of Brazil and Mexico for the Dow Jones (DJ) index, and in the case of Brazil for the Standard and Poor's 500 (SP500) index. In contrast, if the possibility of structural breaks is introduced, strong evidence is found in favour of such a relationship between the Argentine, Chilean and Venezuelan indices and the DJ index after the 1998 financial turmoil, and between the Brazilian and Mexican indices and the DJ index before such turbulence, while some marginal cointegration is detected between the Mexican and DJ indices from February 1998. Additionally, evidence is found of a cointegrating relationship between the Argentine, Chilean and Mexican indices and the SP500 index from August 1998, April 1999 and October 1999, respectively, and between the Brazilian and the SP500 indices before November 1997, as well as some marginal cointegration between the Mexican and SP500 indices before October 1999. The results suggest that the gains from international diversification for investors with long holding periods is limited. 相似文献

SUMMARY Store brands, when moving upscale, inevitably relinquish their value for money appeal and therefore require some quality dimension to compete. This article is proposing that the promise of “generous” use-by dates as a surrogate for quality could be considered as a positioning plank to promote store brands as alternatives to manufactured brands. Logit analysis is employed to explain shoppers' perceptions and responses to use-by dates, of products that they regularly buy, and of alternative products that they have never bought before if the use-by dates of their regular items are perceived to be too short. 相似文献

The neoclassical concept of the market is built on a number of assumptions that lead one to view it as a type of ether, devoid of any institutional content. In opposition to this point of view, this article proposes an alternative characterization of markets based on the fundamental principles of institutional and post‐Keynesian economics. After reviewing the main features that characterize the behavior of economic agents, we analyze the set of interrelations between these agents within markets and the role of institutions in the regulation of these interrelations. Finally, we discuss some of the consequences generated by the institutional dimensions of markets with regard to their origins and evolution, the justification for their existence, or the evaluation of their results. 相似文献
