Generating a causal model of supply chain collaboration using the fuzzy DEMATEL technique

Supply chain collaboration is usually adopted by manufacturers as a strategic measure to increase overall supply chain performance. However, such collaborations arguably have the highest failure record of the various supply chain management practices that are currently being applied. Part of the problem has been the uncertain external environment, an overreliance on technology, and lack of trust among partners. Based on Transaction Cost Economics (TCE) and Relational Exchange Theory (RET), it is clear that environment, asset specificity, and trust are key determinants for the success of collaborations among firms. However, the fuzziness of the interdependency among these determinants and their influences on supply chain collaborative processes still remains unknown. This study thus focuses on Taiwanese manufacturing firms as an example case, and empirically probes the relationships among these dimensions and their effects on these processes. To accommodate the vagueness of human opinions, the fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) technique is applied to examine this issue, and to produce a causal relations map. This study also provides a discussion and insights for supply chain practitioners.     

Determinants of the future level of use of electronic marketplaces: The case of Canadian firms

Based on the literature dealing with the diffusion of innovation and with information systems, and building on the emerging concepts in electronic commerce (e-commerce), this paper aims at assessing the influence of various factors on firms’ future level of use of electronic marketplaces (e-marketplaces). This theoretical model is tested on data collected from 1,200 senior managers in Canadian firms. Findings indicate that a firm’s past experience in e-commerce, as well as the factors relating to its business relationships ultimately affect its future use of e-marketplaces. Results of TOBIT regressions also show that the complexity of sophisticated e-commerce implementations is negatively correlated with the future level of use of e-marketplaces, and that consultants and other experts play an essential role in encouraging and facilitating the use of this new type of electronic platform. Finally, our survey data demonstrate that the relative influence of some determinants differs according to the firms’ size.

The role of intermediaries in electronic marketplaces: developing a contingency model

Abstract. Early research in electronic markets seemed to suggest that e‐ commerce transactions would result in decreased costs for buyers and sellers alike, and would therefore ultimately lead to the elimination of intermediaries from electronic value chains. However, a careful analysis of the structure and functions of electronic marketplaces reveals a different picture. Intermediaries provide many value‐adding functions that cannot be easily substituted or ‘internalized’ through direct supplier–buyer dealings, and hence mediating parties may continue to play a significant role in the e‐commerce world. In this paper we provide an analysis of the potential roles of intermediaries in electronic markets and we articulate a number of hypotheses for the future of intermediation in such markets. Three main scenarios are discussed: the disintermediation scenario, in which market dynamics will favour direct buyer–seller transactions; the reintermediation scenario, in which traditional intermediaries will be forced to differentiate themselves and re‐emerge in the electronic marketplace; and the cybermediation scenario, in which wholly new markets for intermediaries will be created. The analysis suggests that the likelihood of each scenario dominating a given market is primarily dependent on the exact functions that intermediaries play in each case. A detailed discussion of such functions is presented in the paper, together with an analysis of likely outcomes in the form of a contingency model for intermediation in electronic markets.     

The application of Web ATMs in e-payment industry: A case study

Today’s highly competitive marketplace is forcing the retail banking industry to optimize every possible revenue-generating opportunity. New electronic channels are replacing the more traditional ones. Web ATMs system represents one of the recent developments in financial service distribution.Through a real-life case study, this article explains how much more advantage can be achieved by enhancing Web ATMs with the latest Web-enablement technology, and examines the key benefits that can accrue from the deployment of integrated circuit (IC) card and smart card reader on Web ATMs. Last but not the least, it is expected that this article could provide strategic thinking with some apocalypses of Web 2.0 to steer the banking system for achievable changes in a direction that is consistent with the needs and expectations of a population, especially in C2C business model.     

Trustworthiness in electronic commerce: the role of privacy, security, and site attributes

While the growth of business-to-consumer electronic commerce seems phenomenal in recent years, several studies suggest that a large number of individuals using the Internet have serious privacy concerns, and that winning public trust is the primary hurdle to continued growth in e-commerce. This research investigated the relative importance, when purchasing goods and services over the Web, of four common trust indices (i.e. (1) third party privacy seals, (2) privacy statements, (3) third party security seals, and (4) security features). The results indicate consumers valued security features significantly more than the three other trust indices. We also investigated the relationship between these trust indices and the consumer's perceptions of a marketer's trustworthiness. The findings indicate that consumers' ratings of trustworthiness of Web merchants did not parallel experts' evaluation of sites' use of the trust indices. This study also examined the extent to which consumers are willing to provide private information to electronic and land merchants. The results revealed that when making the decision to provide private information, consumers rely on their perceptions of trustworthiness irrespective of whether the merchant is electronic only or land and electronic. Finally, we investigated the relative importance of three types of Web attributes: security, privacy and pleasure features (convenience, ease of use, cosmetics). Privacy and security features were of lesser importance than pleasure features when considering consumers' intention to purchase. A discussion of the implications of these results and an agenda for future research are provided.     

An analysis of privacy signals on the World Wide Web: Past, present and future

Electronic commerce is now an established, vital part of the world economy. However, this economic sector is currently endangered by consumers’ well-founded concern for the privacy of their information. Recent surveys indicate that this concern is beginning to alter consumers’ spending habits. The World Wide Web Consortium is well aware of these concerns, and has produced the Platform for Privacy Preferences Protocol as a mechanism to help consumers protect their online privacy. This mechanism relies on the use of machine-readable privacy policies, posted on a website, and interpreted by a client-side browser extension. However, recent surveys indicate that adoption of this technology is stagnating on the server side, and work on an updated version of the Platform has been halted. We use signaling theory as a framework to model the likely future evolution of the Platform, in an effort to gauge whether it will flourish or wither as a technology. We find that signaling theory predicts the collapse of the Platform for Privacy Preferences Protocol. However, we also find theoretical and empirical grounds to predict that government intervention can drive adoption of the Platform on the server side, which may in turn bootstrap user adoption of this technology.     

The adoption and diffusion of e-commerce in developing countries: The case of an NGO in Jordan

The case study in this research involves a nongovernmental organization (NGO) in Jordan in the Middle East, which attempted to utilize electronic commerce (EC) to streamline its business processes and information flow to businesses in Jordan and to other international businesses interested in the Jordanian market. The NGO managed to achieve these tasks expeditiously, and its EC initiative assisted in adding an effective digital parallel to existing systems and processes in this NGO. The NGO is directly involved in the e-government initiative empowered by H.M. King Abdullah II. At this end, with this royal support, the NGO successfully adopted EC. During the adoption and implementation process, the organization encountered numerous difficulties, as detailed in this research. However, the full success of EC was hampered by other factors. Initially, other governmental entities related indirectly to this NGO were not EC-ready. Second, although Web site utilization was growing in this NGO, most member merchants were reluctant to switch to the online arena and to abandon traditional practices in obtaining information and resources from this NGO. However, the NGO is aware of these concerns and envisages resolving such hurdles in its medium- to long-term projections. © 2007 Wiley Periodicals, Inc.     

Gratifications and social network service usage: The mediating role of online experience

This paper incorporates dual theories from communication research (uses and gratifications) and psychology research (online flow) to examine consumer behavior in the use of social network services. In particular, the study proposes that consumers’ online experience of interaction and arousal serves as the mediator of the relationship between social motivations and use behaviors. The empirical results indicate that arousal fully mediates the relationship between social gratifications and problematic social network service use. Furthermore, both interaction and arousal are partial mediators of the relationship between social gratifications and the intention to revisit social networking websites.     

The choice of governance mode in ICT alliances: A property rights approach

We employed a property rights approach to formulate a set of hypotheses explaining the choice between equity and non-equity alliances in the Information and Communication Technology industry. The firm's need to control knowledge exchange and the resulting innovation makes property rights an important concern permeating partners’ strategic behavior. We showed that equity alliances were preferred, when partners kept a competitive relationship and followed a diversification strategy. However, non-equity alliances were preferred, when partners exhibited high resource complementarity. Finally, our research indicated that, when alliances targeted innovation development, prior ties between partners positively affected the choice of equity alliances.     

The new neighbourhood in the internet era: network communities serving local communities

The past two decades have witnessed many attempts to transform online communities in new neighbourhoods of the Internet era. In particular, one of the most interesting applications of Internet Technologies in this field have been ‘network communities’, that differ from online communities because they refer to a specific territory and, for this reason, serve as a social catalyst for the corresponding territorial community. Network communities, as virtual neighbourhoods, have the purpose of allowing a better understanding of physical ones, contributing to the creation and the proliferation of services most suited to the needs of residents. For this reason, municipalities and local governments should consider the opportunity to exploit network communities as useful tools for local community management. Following this lead, this article analyses a real case study and highlights the existence of a positive correlation between a constructive utilisation of a network community by its members, their sense of community and the degree of their involvement in local problems.     

Evolution of railway network flexibility: The Spanish broad gauge case

The length of the Spanish broad gauge network has decreased in the 1956–2006 period. When looking at different railway maps through this period, it seems that the network is offering fewer and fewer alternatives when a line is cut, that is, the network is becoming less and less flexible. The goal of this article is to prove that the flexibility of the Spanish broad gauge network has decreased substantially in the 1956–2006 period. We have considered the network as a graph (ignoring traditional railway quality indicators such as commercial speed, number of tracks, electrifications, signaling, …) and we have chosen two simple indicators as accurate in this sense: the number of cycles (cycles provide an alternative to reach a station if there is a problem in one line) and the number of stations of intermediate degree. To achieve this, we have developed a piece of software that is an ad hoc extension of Maple’s networks package.     

Design of a multimode beamforming network based on the scattering matrix analysis

The investigation of the multimode beamforming network (BFN) has been developed from its scattering matrix (S-matrix) analysis. A substrate integrated waveguide (SIW) BFN is designed and fabricated on a single Rogers 5880 substrate. This device is not only marked by features of conventional BFN, such as Butler matrix, but also has additional benefits, e.g. more compact configuration and higher radiation efficiency. Measured and simulated results based on the proposed structure are in a good agreement, which indicates that this novel type of BFN has good characteristics and presents an excellent candidate in the development of intelligent microwave and millimeter-wave multibeam antenna systems.

Examining the role of perceived value in virtual communities continuance: its antecedents and the influence of experience

Although perceived value has long been recognised as an influential means of affecting continuance intention in information systems (IS), little attention has been devoted to explore its antecedents, which constitutes an important research issue. This study, building on prior literature on continued usage in IS as well as the resource-based view, proposed a model to address this gap. Our model suggests that perceived value, a major driving force for members’ satisfaction and continuance intention, is affected by four kinds of resources embedded in virtual communities, which are relationship resources, technology infrastructure, knowledge resources and human resources. To provide additional insights on the pivotal role of perceived value, we also postulate that experience moderates the link between perceived value and its antecedents. Data collected from 235 members of a professional virtual community provide strong support for the research model. It was found that perceived value exerts a great effect on both satisfaction and continuance intention. In addition, when different levels of experience are taken into consideration, relationship resources, knowledge resources and human resources were found to be more salient to high-experience members, whereas technology infrastructure was found to be more salient to low-experience members. Finally, this study discusses the implications of these findings and offers direction for future research.     

Using interpretive structural modeling and fuzzy analytical process to identify and prioritize the interactive barriers of e-commerce implementation

The main purpose of this study is to present a novel and useful application of a specific analytical technique to indicate the interactions and calculate the ranking of the barriers of electronic commerce (EC) in the Iran Khodro industrial group, a leading Iranian automotive company, using the combination of two techniques: interpretive structural modeling (ISM) and the fuzzy analytical network process (FANP). Based on an in-depth review of the relevant literature and interviews with managers and experts from the company, thirteen barriers and challenges to the implementation of e-commerce were determined and categorized into four main factors: technical, organizational, individual, and environmental. In the following step, the ISM technique is applied to construct a structural graph and identify inherent interactions among these barriers. The FANP is then used to quantify the relationships and weigh the significance of these barriers. The results obtained from the proposed model reveal that a “lack of awareness regarding the benefits and nature of electronic commerce” is the most important barrier to the implementation of e-commerce. This type of modeling approach can be extremely valuable for companies that wish to focus their efforts and resources on removing the most important barriers and challenges toward the successful implementation of EC.     

Trust, power and interorganizational information systems: the case of the electronic trading community TransLease

This paper focuses on Cap Gemini’s electronic commerce system, TransLease. TransLease is an interorganizational information system (IOS), which facilitates electronic commerce between motor vehicle leasing and repair companies. During our investigation, the system was used by approximately 1000 repair agents working for seven of the UK’s leading vehicle leasing and contract hire companies. This system was originally developed by AT&T and acquired by Cap Gemini in July 1998. At the time of acquisition, the system was seen as being of high strategic value, although it was also seen as underperforming. This paper reports the results of an action research project, which formed one element of the process by which Cap Gemini investigated the former problem. In the paper, TransLease is described as a complex electronic community, dependent upon the existence of symbiotic relationships. As such, the problems that the system users and developers experienced can be attributed to factors that impeded the mutual benefit accruing from participation in the system. The efficacy of the terms of exchange and the degree to which participants mutually benefit through electronic interaction is determined by the complex interplay of a number of relational and organizational factors. The research therefore illustrates the importance of the ‘soft’ organizational issues in IOS management and development, and suggests a conceptual model of the factors relevant in this case. At the time of this study, TransLease was still in the early stages of its life cycle, having only been available in the marketplace for approximately 18 months. During this time, through recognizing the complex problems and issues detailed in this paper, Cap Gemini accordingly redressed the way in which the system was managed and maintained. TransLease is now seen as having matured into a highly successful example of an IOS – a view reflected by its position as market leader in the industry. As this paper will show, the key to improving the existing service has been the emphasis Cap Gemini now places on managing the ‘soft’ aspects of the electronic community.     

An assessment of the use of Transaction Cost Theory in information technology outsourcing

Transaction Cost Theory (TCT) has been widely used in information technology outsourcing (ITO) research to explain and predict outsourcing decisions and outsourcing-related outcomes. This research, however, has led to mixed and unexpected results in terms of the effects of transaction attributes on outsourcing decisions and outcomes. This study assesses the empirical literature employing TCT-based ITO models in terms of its faithfulness to the precepts of TCT, and argues that one possible explanation for the mixed results is that the extant models do not capture all the essential elements of TCT. First, there are core TCT constructs that the extant models do not take into account; second, the linkages among constructs that the IT outsourcing models have hypothesized are not always in line with TCT precepts; and third, the normative nature of the theory is not always captured by the extant models. This paper, therefore, aims to provide one possible answer to the question: “Why have the appropriations made of TCT to study IT outsourcing produced mixed results?”     

The analytic network process for managing inter-enterprise collaboration: A case study in a collaborative enterprise network

In the last years, collaboration among enterprises has gained attention in the business environment as a means to remain competitive. Enterprises that are collaborating look for improving their performance but, in real assessments, they often do not establish efficient frameworks to structure and manage the enterprise association/inter-enterprise performance. In addition, there are many factors that act as barriers to effective collaboration and have to be also properly managed as they impact on the inter-enterprise performance. This paper provides a methodology based on the analytic network process (ANP) to identify and measure, under an integrated approach, both factors and inter-enterprise performance considering their reciprocal impact. With this innovative approach, enterprises will obtain significant information for the decision-making process regarding which are the factors and inter-enterprise performance elements that generate a higher impact and therefore have a high priority within the specific collaborative relationship. Thus, enterprises can focus their efforts on improving those most important factors and performance elements, and consequently, enhancing their competitiveness.     

Consumer's decision to shop online: The moderating role of positive informational social influence

While much of the current literature tends to focus on the direct effect of social influence on consumer online shopping behavior, our study drew heavily on social influence theory and argued for an alternative theory focusing on the moderating role of social influence. In particular, we explored how positive messages in online discussion forums may affect consumers’ decisions to shop online. We used a laboratory experiment in which the treatment group was required to read positive messages about online shopping experience in an online discussion forum. Positive social influence was found to reinforce the relationship between beliefs about and attitude toward online shopping, as well as the relationship between attitude and intention to shop. We believe our alternative theory provides new insight into the complex processes through which social influence is brought to bear on consumers’ online shopping decisions. Implications of our work are discussed.     

Social network analysis of a gamified e-learning course: Small-world phenomenon and network metrics as predictors of academic performance

Social networks and gamification are having an important and growing role in education. Social networks provide unknown communication and connection possibilities while games have the potential to engage students. This paper analyzes the structure of the social network resulting from a gamified social undergraduate course as well as the influence that student's position has on learning achievement. In a semester long experiment, a social networking site was delivered to students providing gamified activities and enabling social interaction and collaboration. Social network analysis was used to build the network graph and to compute four measures of the overall network and nine measures for each participant. Individual measures were then assessed as predictors of students' achievement using three different methods: correlation, principal component analysis and multiple linear regressions. The resulting social network has 167 actors and 2505 links, and it can be characterized as a small-world. All analyses agreed on the potential of structural metrics as predictors of learning achievement but they differ in the measures considered as significant. A moderate correlation was found between most centrality measures and learning achievement.
