Efficient algorithms to detect pricing inconsistency for customizable products

For assemble‐to‐order manufacturers, the production is an assembly of predefined items. Products from these manufacturers are usually sold to customers directly, instead of through resellers. When these manufacturers adopt electronic commerce for their businesses, they explicitly publish the prices for their products in their electronic commerce web sites, and allow customers to make on‐line purchases based on the prices and the customized configurations. It is critical for the manufacturers to ensure that the same type of products has the same price, no matter how a customer does the customization. Unfortunately, pricing inconsistency exists in some electronic commerce web sites due to various reasons. In this paper, we present the problem to be solved at first. Then, we define two types of pricing inconsistency. Finally, we propose efficient algorithms to solve the problem based on reasonable assumptions.

Thematic Modules in an Asynchronous Learning Network: A Scandinavian Perspective on the Design of Introductory Courses

This paper discusses an educational philosophy and proposes a framework for structuring introductory courses in higher education. The philosophy is rooted in a Scandinavian tradition of social settings. Two elements are central in the philosophy: First, the notion of a thematic module (TM) which is a unit for studying a limited subject matter or topic. Second, asynchronous learning networks (ALN), which is the use of computer mediated communication for time and place independent collaborative learning. To evaluate the philosophy, a course, "Introduction to Informatics," was designed and offered to forty-three business administration majors. Three central assumptions of the philosophy guided the design and evaluation of the course. First, thematic modules are appropriate for structuring an introductory course, second, asynchronous learning network is a viable environment to enhance thematic modules, and third, TM in ALN is a suitable approach for educators who wish to engage students and fellow educators in constructive and collaborative learning activities. To investigate the assumptions, both qualitative and quantitative data were collected and analyzed. The quantitative data gathered are very limited, but give indication for further research. The paper ends with a tentative framework for design of introductory courses using TM and ALN.     

Attention,indifference, dislike,action: Web advertising involving users

Since advertising banners in Web pages usually do not relate to the users' interests, banners are often rejected. Much effort has been spent on trying to adapt banners to users. While the usual approach is to try to accomplish that by gathering data about the user, we propose a different approach. Using user‐configurable advertising profiles and direct feedback we give full control to the users themselves. This approach is currently being implemented and evaluated in the context of an Internet TV program guide.

Protocols for automated negotiations with buyer anonymity and seller reputations

In many Internet commerce applications buyers can easily achieve anonymity, limiting what a seller can learn about any buyer individually. However, because sellers need to keep a fixed web address, buyers can probe them repeatedly or pool their information about sellers with the information obtained by other buyers; hence, sellers' strategies become public knowledge. Under assumptions of buyer anonymity, publicly‐known seller strategies, and no negotiation transaction costs for buyers, we find that take‐it‐or‐leave‐it offers will yield at least as much seller profit as any attempt at price discrimination could yield. As we relax those assumptions, however, we find that sellers, and in some cases buyers as well, may benefit from a more general bargaining protocol.

The Relative Importance of Various Promotional Elements in Different Industrial Purchase Situations

Most advertisers perceive the views of economists on advertising as generally negative. This study attempts to determine how the role of advertising in the economic system is treated in basic economic textbooks. The assumption is that the materials presented in these introductory texts are reflective of the discipline's fundamental commonalities. The results derived from conducting a content analysis of non value laden issues indicate that most authors provide readers a balanced treatment of advertising. However, when assessed in terms of comprehensiveness and completeness, the majority of the surveyed texts fall short. These results hold out a number of implications for advertisers and economists alike and present several opportunities for further research.     

An overview of Web 2.0 social capital: a cross-cultural approach

This is an introductory paper for this Special Issue on Web 2.0 Social Capital. We present a general discussion of motivations for and barriers to applying an Enterprise 2.0 approach. Focus then shifts to the specific fields of knowledge sharing and e-commerce. The article continues with an examination of social capital 2.0 issues. Discussion centers on the employee’s perspective of using Web 2.0 applications and on the adoption of corporate Web 2.0 tools for collaboration. Finally, the paper presents a brief background for each of the topics covered in the five articles selected for this special issue on Web 2.0 social capital.     

Groups Formation and Operations in the Web 2.0 Environment and Social Networks

The Internet and the Web are evolving to a platform for collaboration, sharing, innovation and user-created content—the so-called Web 2.0 environment. This environment includes social and business networks, and it is influencing what people do on the Web and intranets, individually and in groups. This paper describes the Web 2.0 environment, its tools, applications, characteristics. It also describes various types of online groups, especially social networks, and how they operate in the Web 2.0 environment. Of special interest is the way organization members communicate and collaborate mainly via wikis and blogs. In addition, the paper includes a proposed triad relational model (Technology–People–Community) of social/work life on the Internet. Particularly, social/work groups are becoming sustainable because of the incentives for participants to connect and network with other users. A discussion of group dynamics that is based on the human needs for trust, support, and sharing, regardless if the setting is a physical or virtual one, follows. Finally, future research directions are outlined.

Real‐estate agent ethics: Selected findings from two Norwegian studies

The article discusses selected findings from two Norwegian studies among real‐estate agents and real‐estate students, and their relevance for real‐estate education in professional ethics. The survey data‐set indicates that the industry morality of real‐estate agents is more peer‐group oriented, less individualistic and more intersubjective than in other comparable Norwegian industries. The qualitative material shows how respondents perceive and discuss three professional role conflict scenarios in a rule‐ or consequence‐focused pattern. The findings are followed by several suggestions relating to conflict handling approaches and professional ethics training among future and present real‐estate agents.     

Negotiating Technology Implementation: An Empirical Investigation of a Website Introduction

Negotiated implementation is suggested as a cogent approach to meeting user and implementer needs, and thus, to increasing technology implementation. Negotiated implementation is expected to have its effect through three wellknown dimensions: ease of use, usefulness, and commitment. The efficacy of negotiated implementation is tested in the context of a universitybased field study of World Wide Web site use. Empirical support is found for the negotiated implementation approach. Implications and future research related to both theory and application are provided.     

Self‐Financing Trading Strategies for Sliding, Rolling‐Horizon, and Consol Bonds

The time evolution of a sliding bond is studied in discrete‐ and continuous‐time setups. By definition, a sliding bond represents the price process of a discount bond with a fixed time to maturity. Examples of measure‐valued trading strategies (introduced by Bj"ork et al. 1997a, 1997b) which are based on the price process of a sliding bond are discussed. In particular, a self‐financing strategy that involves holding at any time one unit of a sliding bond is examined (the wealth process of this strategy is referred to as the rolling‐horizon bond). In contrast to the sliding bond, which does not represent a tradable security, the rolling‐horizon bond (or the rolling‐consol bond) may play the role of a fixed‐income security with infinite lifespan in portfolio management problems.     

模块化组织模式的构建与运作——基于海尔"市场链"再造案例的研究

The concept of modularity can be applied not only to complex product system design, but also to business system interpretation and design. However, the amount of literature on modular organization is much less than that on product modularity. Based upon a case study on Haier’s reengineered business-process system after the “market-chain” reform, this paper examines the course of its process decomposition to form a prototype of modular organization, and further analyzes the evolution of the three key factors in the design rules, which make the independent modules interact with others to form a complex system. The study shows that a system will gain strategic flexibility when more business units in service supplying and product manufacturing are treated as modules of the firm. Meanwhile, a system will become more complex when the number and variety of modules increase, which in turn induces the evolution in the process of the modular organization’s decomposition and integration.

Clement Henry and Rodney Wilson have assembled twelve essaysabout Islamic finance—six about thematic issues and sixabout case studies of Sudan, Kuwait, Jordan, Turkey, Tunisia,and Egypt—plus an introduction and conclusion. Henry and Wilson’s introductory chapter is an excellentsummary of the phenomenon of Islamic banks, including theirorigins, size, and banking practices. The banks largely datefrom the mid-1970s. Purist Islamic economists thought Islamicbanking should be based on profit sharing, in which the depositor’sfunds are     

Trends in ethics and styles of leadership in India

Leadership styles vary across the vast Indian sub‐continent and are in a state of flux and change. The norms are influenced by ancient mythology and by imprints of world‐wide movements of political liberalism, socialism and economic globalization. But through all these styles, one discerns basic values which are universal and can be intuitively grasped by multi‐national managers. The paper describes the various sources of leadership understandings in India and relates them to Western traditions, notably to Aristotle's 'virtue ethics'.     

Relationship marketing: Back to basics?

Relationship marketing, however defined, has received considerable attention recently. To its advocates, relational exchange between buyer and seller represents a paradigm shift away from the traditional focus on individual transactional exchanges. Critics of relationship marketing argue that the concept is poorly defined and is merely a new way of describing what businesses have been doing for a long time.

This paper recognizes that the need to develop long‐term relationships between an organization and its customers is becoming greater. It is however questioned whether marketing educators are providing students with the abilities to take a mature approach to relationship marketing issues, in line with the changing nature of employers' business. Suggestions for introducing relationship marketing to the undergraduate syllabus are made at a number of levels, from an additional module for an introductory “principles of marketing course” to a multi‐disciplinary degree majoring in relationship marketing.     

Using the training reactions questionnaire to analyze the reactions of university students undergoing career‐related training in Jordan: a prospective human resource development approach

The primary purpose of the present study was to validate Morgan and Casper's training reactions questionnaire (TRQ) for use in Jordan. The study also investigated the reactions of university students to career‐related training programs. Another purpose of the study was to determine the impact of certain aspects of training programs on the overall satisfaction of university students with the quality of the programs. The validated TRQ was administered to a purposive sample of 304 participants who completed at least two training programs. Results showed that the TRQ is valid for use in Jordan. Results also indicated that participants exhibited high levels of satisfaction with all aspects of the training programs completed. Further, based on regression analyses, results indicated that utility of training had the highest explained variance followed by course materials and course structure. Finally, the study provided a number of practical and theoretical implications for the field of study.     

Case Study of Customer Relationship Management (CRM) in the On-Line Affluent Financial Services Market

ABSTRACT

In the current period of constrained economic conditions, this study initiates an analysis of customer relationship management (CRM) on the Web sites of financial service businesses. Customer relationship management is a critical differential that enables competitive edge for businesses focused on the affluent customer market. Though investment in marketing, sales and service innovation is limited under existing conditions, the analysis of the study on large financial businesses indicates that the businesses enable higher commerce, content and context, but lower and generally inadequate communication, community, connection and customization design on their Web sites. The analysis, conducted as an assignment by adult graduate students in an information systems course, contributes important insight into the competitive dynamics of customer relationship management for Web empowered financial service businesses striving to service the demanding affluent market. This study furnishes an expanded framework to research customer relationship management of financial service businesses competing in the paradigm of the Web.     

The Politics of Resisting and Reforming Systematic Extortion by Tax Auditors-inspectors

The problem this paper addresses is network based, systematic tax extortion. Four key extortion system elements are considered which expose corruption links between political, administrative and judicial bodies. Based on action‐learning theory, a number of intervention methods for resisting and reforming systematic tax extortion are considered. The strengths and limitations of the methods are considered in the context of a number of case studies. Since the problem of tax extortion is more network based and systematic than it is isolated and individual, any successful method of intervention must target network processes rather than isolated individual behaviours. What appears particularly promising is a social movement‐based combination and sequence of methods that includes dialogue among reformers about system‐level problems, win‐win alliances with instrumental allies, and win‐lose methods against selected opponents to extortion reform.
