People with severe motor disabilities have extreme access difficulties with all kinds of web services especially when they want not only to surf the web, but also write some text, e.g., to participate in an e-activity. Several problems arise when using traditional scanning systems, such as the low text entry rate, the time consuming task of learning the scan matrix layout, or simply, the poor visibility of the web page due to the large surface needed to display the complete scan matrix on the screen. We propose a reduced virtual keyboard based on scanning with only one switch as input device. The scan matrix consists of only three cells, so ambiguity is present due to the assignment of 26 characters to the three keys. Word-level and character-level disambiguation modes are explored using a mathematical model, and the text entry rates for an expert user were 15.9 and 10.3 words per minute respectively, using a scan period of 0.5 seconds. This keyboard could be embedded into a web page using a Java applet, JavaScript code or a Flash application, or be programmed as an independent application. Full article

The rapid growth of data communications networks in recent years has led to enormous development in electronic commerce. Internet banking and trading are two important applications that execute financial transaction from anywhere in the world. This enables banks and merchants to simplify their financial transaction process as well as to provide customer friendly service 24-hours a day. On one hand the cost of manpower and infrastructure comes down drastically and on the other hand the cost of transportation, third party royalty and securing customer information is increased. Electronic micro-payment is one of the most important research topics in electronic commerce, particularly, low-cost online payment scenarios and offline payments in rural areas. In this paper, we discuss some of the important micro-payment schemes, observe their merits and limitations, and then propose an improved micro-payment scheme. We discuss two basic micro-payment schemes, which use the public/private key concept and then we review another scheme that uses the concept of hash chain. We observe certain limitations in these and related schemes, which motivate us to extend one of the attractive schemes, namely, the Hwang and Sung’ scheme [8], towards more efficient, retaining all other features intact without compromising the security strength of the scheme. We compare the improved scheme with others and show that the improved scheme provides better security and efficiency, which enables the scheme viable for real-world applications, in particular, in resource-constrained environments such as mobile payment through handheld devices or customer’s chip card for debit/credit transaction through point of sale terminal.

In order to support the execution of collaborative business processes, trading partners have to exchange electronic business documents. Since each partner has its own systems and culture, they could use different terms and metadata structures to represent their data, even when referring to the same domain of interest. Then, an appropriate approach for defining the semantics of these documents is required to achieve semantic interoperability. To this aim, a number of approaches have been proposed based on the use of a single domain ontology. These approaches imply the imposition of a global meaning of terms, which are used to represent the entities of a domain. This goes in opposition to one of the aims of trading partners, which is to participate in collaborative business processes without losing their autonomy and privacy. In this scenario, it is necessary to define a framework for allowing trading partners to exchange information without imposing a global meaning of it. In this paper, a novel approach is proposed in order to define the semantics of the electronic business documents interchanged between trading partners in a collaborative relationship. This approach is based on the idea of making some domain features, which are generally implicit, explicit in the domain ontologies. An application example of this approach is also presented.

Any e-organization, whether it is commercial or governmental, requires a knowledge management support in order to achieve optimal performance. Many of the technologies that serve the operations of such organizations can also support knowledge management to facilitate efficient knowledge sharing and reuse. Thus, eorganizations should be at the forefront in the use of knowledge management. This paper examines systems of knowledge management used in large organizations. The limitations of traditional organizational schemes are examined, including the tie to the traditional pre-digital knowledge unit, the multi-page document. An action research approach is taken towards the question of how we improve upon traditional approaches using the technology available in conjunction with approaches arising from organizational research. A new framework is described where knowledge is packaged into objects and classified by organizational performance roles and goals. A prototype implementation of the framework was developed in order to test its feasibility. Evaluation of the prototype suggests that the system could result in a more intuitive organizational framework that enables workers to obtain appropriate knowledge support in a timely manner without the need for extensive search, and also facilitates greater reuse and sharing of knowledge.

The paradigm of service-oriented computing (SOC) has emerged as an approach to provide flexibility and agility, not just in systems development but also in business process management. This modular approach to defining business flows as technology independent services has gained unanimous popularity among end-users and technology vendors alike. Although there is a significant amount of ongoing research on the potential of service oriented architectures (SOAs), there is a paucity of research literature on the factors affecting the adoption of service-oriented computing in practice. This paper reviews the current state of the technology, identifies the factors influencing the decision to adopt service-oriented computing as an enterprise strategy and discusses the associated research literature, and concludes with a suggested research agenda and conceptual framework for investigating the use of service-oriented computing in practice.

Structural changes and increasing market dynamics in the health care sector intensify the hospitals’ needs for cost-savings and process optimization. The adoption of new information and communication technology (ICT) is thereby seen as opportunity to improve not only efficiency and effectiveness but also the quality of health services. As costs for drugs continuously increase, especially hospital pharmacies will be in need of acquiring expertise and technology in order to enhance the sourcing processes. The diffusion of e-procurement is however slow in this area. To investigate why hospital pharmacies only have a modest adoption rate of eprocurement, case studies of three distinct Swiss hospitals with differing organizational structure and automation degrees are presented. It will be shown that technological as well as organizational change is needed in order to efficiently use e-procurement in future. Full article

The likelihood that one organization can pressure the e-business adoption practices of other organizations depends on two conditions: there must be sufficient power difference between the organizations; and the ebusiness process benefit must be sensitive to the number of adopters. Given these two conditions, the powerful organization can use their power advantage to control adopter numbers through urging or suppressing adoption by others. Examples from practice are provided, a theoretical framework capturing the three dimensional nature of e-business adoption influence is developed, and Game Theory is used to explore the range of possible outcomes when pressure to adopt is brought to bear between organizations of unequal power.

In the turbulent world of e-commerce, companies can only survive by continuously reinventing their business models. However, because most studies look at business models as snapshots in time, there is little insight into how changing market-related, technological and regulatory conditions generally drive revisions in business models. In this paper, we examine which types of external drivers are strongest in forcing business models to change throughout their life cycle. To do so, we study 45 longitudinal case descriptions on business model dynamics of (networks of) organizations in various industries. The results of this survey indicate that technological and market-related forces are the most important drivers of business model dynamics, while regulation plays only a minor role. In particular for start-ups, the effect of technological and market-related drivers is the strongest in the early stages of a new business model, while the effects are moderate over time for established, large companies. Our results provide clues to practitioners on what external factors to take into account in different stages of business model design and redesign. Full article
