  • Recently introduced by the major credit card associations as replacements for the decommissioned SET and 3DSET protocols, the new payment models, 3DSecure and UCAF/SPA, have been designed to provide online merchants with a solution to an existing problem in online credit card transactions - the lack of an effective and efficient means of authenticating cardholders. The expected benefits arising from this added level of security from the merchant′s perspective are increased consumer confidence, significant reduction in the levels of fraud and charge backs and "liability shift". Using data gleaned from preliminary interviews, discussion forums and promotional material, we present a critical analysis of the potential barriers and facilitators that will impact on the widespread traction of these programs in the marketplace in the coming years.

  • In ubiquitous computing environment such as ubiquitous marketplace (u-market), there is a need of providing context-based personalization service while considering the nomadic user preference and corresponding requirements. To do so, the recommendation systems should deal with the tremendous amount of context data. Hence, the purpose of this paper is to propose a novel recommendation method which provides the products-group list of the customers in u-market based on the shopping intention and preferences. We have developed FREPIRS(FREquent Purchased Item-sets Recommendation Service), which makes recommendation listof product-group, not individual product. Collaborative filtering and apriori algorithm are adopted in FREPIRS to build product-group.

  • This article is concerned with choice-based conjoint analysis versus rating-based and ranking-based conjoint analysis. Choice-based conjoint analysis has a definite advantage in that the respondent's task of choosing the most preferred profile from several competing profiles adequately mimics consumer marketplace behavior. It is crucial to design the choice sets appropriate for the choice-based conjoint. Thus, this article suggests a new method to design the choice sets that are well-balanced. It augments the balanced incomplete block design and then obtains the dual design of the result to accommodate various numbers of profiles. In consequence, the choice sets designed by the new method have the desirable characteristics that each profile is presented to the same number of respondents, and pairs of any two distinct profiles occur together in the same number of choice sets. The balancing of the design increases the efficiency of the conjoint analysis. In addition, the pair-comparison scheme can improve the quality of data through the identification of contradictory responses.

  • The underlying success of logistics depends on the flow of data and information for effective management. Over the last 30 years, we have seen the power of microprocessors double about every 18months. This continuing trend means that computers will become considerably smaller, cheaper, and more abundant; indeed, they are becoming ubiquitous and are even finding their way into everyday objects, resulting in the creation of smart things. In the long term, ubiquitous technologies will take on great economic significance. Industrial products will become smart because of their integrated information processing capacity, or take on an electronic identity that can be queried remotely, or be equipped with sensors for detecting their environment, enabling the development of innovative products and totally new services. The global marketplace runs on logistics, security, speed, agility and flexibility..In this paper we report that pairing these traditional logistics functions with RFID technology can be a huge value-driver for companies. This winning combination yields increased logistics management effectiveness and more efficient visibility into the supply chain management.

  • Due to the low usage level of traditional financial services in many developing countries, Fintech services that often substitute for such traditional services with greater convenience have great potential in these markets. However, there have thus far been relatively few attempts to examine Fintech adoption in developing countries. As financial services are a highly sensitive industry in terms of government regulation and consumer trust, it is critical for policymakers to understand how to foster a healthy Fintech marketplace in developing country environments. In this paper, we review the scholarly literature on Fintech adoption with respect to three stakeholder groups: customers, service providers, and policymakers. Adding with practitioner-oriented documentation relating to Fintech adoption in Vietnam, we derive propositions for Fintech adoption research in Vietnam and similar developing countries. We collect these propositions as a framework that suggests avenues for future research.

  • The objectives of this research are to test the utility of semiparametric geographically weighted regression (SGWR, a spatial analysis method) in the small-scale urban sample, and to understand the geographic patterns of provision and pricing of sharing economy based accommodations in the tourist city. This paper focused on how network distance to heritage site, to casino, residential unit prices and other five attribute categories determine Airbnb price in Macau SAR, China. Findings show that SGWR models outperformed OLS models. Moreover, comparing with heritage sites, casinos are the stronger factors to drive up Airbnb (including hostels) rooms' provision and their prices; and residential unit prices are not related with the Airbnb price in the attraction clusters in Macau. This research showed a little example for the applications of SGWR in the small city, and for the analysis of online marketplace data as new urban study material. Practically, this study provides some scientific evidence for hosts, guests, urban planners, and policymakers' decision making in Macau.

  • This study investigates which variables most effectively influence the positioning strategy of a brand. In addition, we test the connection between the positioning strategy of the brand and loyalty. Finally, we explore how brand experience effects the relationship between brand position and brand loyalty. To this end, this study employs the street-intercept method to collect data on consumers' perception of home appliances in Japan and conducts structural equation modeling analysis to test our hypotheses. Specifically, we find that assessments of product, service, and image have a significant impact on a brand's position which, in turn, drives brand loyalty. In addition, brand experience seems to moderate the relationship between service and brand positioning effectiveness. We also find that price promotions negatively affect brand loyalty. The research provides a consumer-centered, experiential view of how firms can develop strategies to more effectively position brands and increase loyalty among their customers. These results help both academics and practitioners to better understand how consumers assess a brand's position in the marketplace.

  • 본 연구는 공간정보의 협력적 활용을 위한 커뮤니티 지원 프로그램인 미국 NSDI의 CAP(Cooperative Agreements Program)을 대상으로 공간정보 커뮤니티 활성화 방안과 그 효과에 대해 살펴보았다. 커뮤니티 지원을 위해 CAP에 채택된 20여개 카테고리의 변화 추세와 10년간 지원된 350여개의 사례를 살펴본 바, 지원 카테고리는 NSDI가 2004년 'Future Directions Initiative'를 발표한 시점을 기준으로 메타데이터 중심의 표준화 보급 부문 위주에서 파트너십 강화와 연계하여 NSDI의 모든 구성요소를 CAP 프로그램의 지원 카테고리로 적용하는 변화가 이루어졌다. CAP의 역할과 관련해서는 커뮤니티를 NSDI의 확장성과 지속성의 핵심요소로 파악하고 공간정보 사용자 역할만이 아닌 공급자로서의 역할을 강화하기 위한 실행방안으로 CAP을 활용하였다. CAP의 효과로는 커뮤니티 활성화에 따라 수요자가 다양화되어 공간정보시장 내 수요를 확대하고 비즈니스 부문이 활성화되는 등의 공간정보시장 구조의 개선에 긍정적 역할을 한 것으로 나타났다.

  • Information scientists need not to answer whether future libraries will be a digital library or not, but to answer how they are structured and served effectively to users currently. 'The library with walls' or 'the library as place' need to be existed in the future, but 'digital library without the wall' or 'virtual library' will need to be studied continuously. This study has tried to reveal the existing problems of digital libraries and their future environment after considering the ambiguous concepts of various types of electronic libraries and their efforts for library automation, and the changed information retrieval circumstances during the last 30 to 40 years through a qualitative document study. As a result, the major findings and suggestions are prepared. The library of the future will be a part of local and national cooperative systems, be filled with the intelligent use of old and new technologies, and be able to su n.0, pport both a place with extensive collections and convenient, easy, & free access to remote intellectual resources. Also, the information storage and retrieval (ISAR) to the future library system would easily provide users with any types of data retrieval system by anybody rather than by an expert or a specialist, so called 'A&E retrieval' in the coming 21th century. It will be highly possible that the future society changes to the information marketplace whose data may be recognized as an intangible assets.
