Prior to conducting business via the Web, business partners agree on the business processes they are able to support. In ebXML, the choreography of these business processes is described as an instance of the so‐called business process specification schema (BPSS). For execution purposes the BPSS must be defined in the exact business context of the partnership. Reference models for B2B processes developed by standard organizations usually span over multiple business contexts to avoid a multitude of similar processes. In this paper we present how business collaboration models following the UN/CEFACT Modeling Methodology (UMM) are expressed in ebXML BPSS. To allow a mapping from multi‐context business collaboration models to a context‐specific choreography in ebXML BPSS we extend UMM to capture constraints for different business contexts

There is a growing demand worldwide for the adoption of Learning management systems (LMS) by academic institutions to support e-Learning platform. Yet limited research has been conducted to investigate the factors affecting its usage, particularly by university instructors. To fill this research void, the expectation-confirmation model (ECM) was used as the core framework for analysis, while additional critical independent factors related to organizational, technological and individual characteristics were added to find a better model to understand university instructors’ continuance intention to use Blackboard system as a popular LMS.

Sample data were gathered from 158 university instructors at a university in the United Arab Emirates (UAE) who volunteered to participate in this study. Structural equation modeling technique was used to verify the causal relationships between the constructs.

Perceived usefulness (PU) affected satisfaction of Blackboard system. Both PU and satisfaction affected instructors’ continuance intentions to use Blackboard system. User-interface design affected both PU and satisfaction. Technical support influenced perceived usefulness. Training influenced perceived usefulness, but it had no influence on satisfaction. Computer self-efficacy had no influence on perceived usefulness.

Based on the ECM, this study contributes significantly to the limited body of research on capturing the influence of organizational, technological and individual motivators to explain university instructors’ continuance intention to use LMS.

This paper aims to improve the recommendations performance for cold-start users and controversial items. Collaborative filtering (CF) generates recommendations on the basis of similarity between users. It uses the opinions of similar users to generate the recommendation for an active user. As a similarity model or a neighbor selection function is the key element for effectiveness of CF, many variations of CF are proposed. However, these methods are not very effective, especially for users who provide few ratings (i.e. cold-start users).

A new user similarity model is proposed that focuses on improving recommendations performance for cold-start users and controversial items. To show the validity of the authors’ similarity model, they conducted some experiments and showed the effectiveness of this model in calculating similarity values between users even when only few ratings are available. In addition, the authors applied their user similarity model to a recommender system and analyzed its results.

Experiments on two real-world data sets are implemented and compared with some other CF techniques. The results show that the authors’ approach outperforms previous CF techniques in coverage metric while preserves accuracy for cold-start users and controversial items.

In the proposed approach, the conditions in which CF is unable to generate accurate recommendations are addressed. These conditions affect CF performance adversely, especially in the cold-start users’ condition. The authors show that their similarity model overcomes CF weaknesses effectively and improve its performance even in the cold users’ condition.

No matter where you look there seem to be news stories, journal articles, and television and radio programmes about e‐commerce. Indeed, this has now moved on from e‐commerce to e‐business and more recently to m‐commerce. There are a lot of websites covering e‐business /e‐commerce and I have tried to trawl through these sites and pick out some of the best that are available.

To examine supply chain competences necessary to efficiently and/or effectively succeed in aftermarket support.

Using the aerospace industry as a context, this paper provides a brief overview of aftermarket support practices and trends and discusses the broader implications for aftermarket supply chain managers.

There are multiple approaches to aftermarket support. Which approach should be used depends on key variables including: technology, need for visibility and/or traceability, and need for collaborative product commerce.

This paper is a general review. Future research should examine resources necessary in individual industries, other forms of relationships, and the influence of new technologies.

In many industries, there are significant opportunities for incremental profit in aftermarket support. Collaborative product commerce, alliances, a number of new technologies (e.g. web commerce), and security needs may play critical roles in determining whether or not a company's aftermarket support practices will be profitable. Firms without competences in these areas should seek help from trusted partners to fill competence gaps.

This paper explores an often ignored but significant line of business – aftermarket support. Lessons demonstrated in this paper may be used in a number of industries that rely on aftermarket support for incremental profit.

With the Internet, companies can access a broader range of trading partners and exchange detailed information more quickly and more cheaply than ever before.

This paper seeks to examine how auditors sought to establish their trustworthiness as trust providers on the internet; a vision which has remained largely unrealized. The investigation focuses on the WebTrust assurance project, launched by the North American accounting institutes to reinvigorate the alleged declining market for the expertise of external auditors.

An in‐depth longitudinal case study drew on a social theory of trust to examine the complexity of relations upon which trustworthiness of professional claims is predicated and investigate how commercialism has influenced the development of WebTrust.

Analysis illustrates the critical role that experts have in professionalization processes in trusting (or not) their own systems of expertise. Also, face‐to‐face relationships continue to play a key role in establishing the trustworthiness of professionals and their systems of expertise – even in the cyberspace domain.

It is argued that the WebTrust case and other commercialistic ventures sustained in accountancy provide a persuasive argument against the benefits of the free‐market logic in professional domains. Professional associations should be more vigorous in defending professionalism.

The research indicates that élite bodies of the profession, including professional associations, conceived of WebTrust mainly through a commercialistic lens – which is particularly revealing of the mindset that seemed to characterize a number of experienced professional accountants across North America shortly before the collapse of Andersen. The WebTrust saga illustrates how the profession has strayed from its ideals, or myths, of service ethic towards more focused efforts in developing “innovative” services based on a commercialistic logic.

B2B e‐hubs have been studied by IS researchers for close to a decade, and supply chain integration is a critical topic for supply chain management. However, the interface of the two topic areas has not received adequate attention from both researchers and practitioners. This paper aims to examine the impact of B2B e‐hubs on supply chain integration, with particular emphasis on information integration, B2B e‐hub architecture, and enabling technologies.

General system theory (GST) provides the theoretical framework. The main approach is theoretical analysis of information integration and development of e‐hub architecture. The paper discusses how information integration can be achieved through B2B e‐hubs and explores extensible markup language e‐hub architecture and technologies.

GST could provide the theoretical framework of integration, whereas information integration is the foundation of broader supply chain integration. E‐hubs open up communication and enlarge networking opportunities and thus tremendously affect information integration. By analyzing B2B e‐hubs, this paper explores the mechanism of information integration and points out managerial and technical limitations. Although there are many challenges, e‐hubs create value by aggregating and matching buyers and sellers, creating marketplace liquidity, and reducing transaction costs. E‐hubs could be a crucial solution to supply chain integration.

The paper uses GST as the theoretical foundation to analyze information integration in supply chain operations. The paper explores how e‐hubs can support supply chain integration, examines the design and development of B2B e‐hub architecture, and compares some enabling technologies. The research provides an understanding of how data interchange solutions can be implemented in supply chain operations.

This study aims to examine e-commerce within UK small and medium sized enterprises (SMEs). More specifically, it seeks to explore associations between e-commerce and internal and external antecedents including trading behaviour, owner/manager characteristics, innovation, public sector involvement, business advice and finance sources.

An 8,500+ sample derived from the 2008 UK Federation of Small Businesses survey was utilised. An OLS regression equation was generated where the percentage of sales made using e-commerce constituted the dependent variable. Independent variables were constructed for several sets of factors including innovation, business advice and sources of finance, as well as a range of owner and SME typology variables.

The results suggest that e-commerce is more strongly apparent in SMEs started from scratch and where they were involved in basic or high knowledge services or the tourist trade. SMEs undertaking e-commerce were also associated with innovation in the form of copyright, as well as public procurement with local authorities and the university sector. Specific business advice in the form of capacity, family and suppliers was also associated with e-commerce trading.

These results have implications for SMEs and public sector stakeholders. SMEs must recognise the importance of several potential antecedents such as intellectual property rights, specific business advice and finance to encourage e-commerce. Moreover, it was apparent that certain SME characteristics, namely locality and trading behaviour, were associated with effective e-commerce.

This study will be of value to academia, SMEs and key public sector stakeholders in the formulation of policy for ICT development.
