Abstract: Due to a rising interest in empirical ‘respect’ research but at the same time a somewhat fuzzy use of the term and its semantically close neighbors, we introduce a conceptual framework. The framework draws on existing philosophical traditions and empirical psychological works alike. It is pointed out that respect, acceptance, and tolerance are all attitudes of a subject towards an object which are not aligned on one dimension, but are concerned with quite different issues. Moreover, we propose that research needs to differentiate between two very different kinds of respect. Whereas appraisal respect, acceptance, and tolerance are attitudinal reflections of a subject’s decisions on certain issues (i.e., on influence, membership, and presence), recognition respect is proposed to be an overarching processing mode, i.e., a general attitude on how to confront others.

Abstract: The consumer electronics industry is a $240 billion global industry with a small number of highly competitive global players. We describe many of the risks associated with any global supply chain in this industry. As illustration, we also list steps that Samsung Electronics and its subsidiary, Samsung Electronics UK, have taken to mitigate these risks. Our description of the risks and illustration of mitigation efforts provides the backdrop to identify areas of future research.

Abstract: Purpose – Service‐oriented architecture (SOA) is an architecture paradigm targeting integration of applications within and across enterprise boundaries. It has gathered research and industry acceptance and has given an enormous impetus to the business process management technology. Web service (WS) technology is one implementation of the SOA paradigm. It enables seamless integration of new and legacy applications through a stack of standardized composable specifications. WS orchestration is facilitated by the Business Process Execution Language which provides a recursive service composition model. While the programming model the WS technology provides is very flexible, a major deficiency is the need to discover services implementing a particular abstract interface, whereas functional similarities of services are disregarded. The Semantic Web Service technologies, like Web Service Modelling Ontology (WSMO) and Web Ontology Language for Services have been developed with the purpose of eliminating these deficiencies by enabling service discovery based on functional and non‐functional properties. The paper aims to focus on these issues.Design/methodology/approach – This paper presents a list of requirements that business processes impose on SOA applications. It analyzes the support that WSMO/Web Service Model eXecution environment (WSMX) provides to address these requirements and compares it with the support enabled by the WS specification stack.Findings – The paper identifies major flaws in the WSMO model and its reference implementation with respect to business process support.Originality/value – The paper recommends possible solutions for eliminating the lack of needed features on behalf of WSMO/WSMX. It presents in detail how to enable asynchronous stateful communication among WSMO WS and partner‐based WS discovery by extending the WSMO model. Additionally, it extends the API of the reference implementation to facilitate the execution of services communicating asynchronously.

Abstract: Previous empirical research on order of entry effects shows strong evidence for the existence of a first-mover advantage. Conventional strategic recommendations are therefore based on the assumption that pioneering is preferable in order to create competitive advantages. However, theoretical work has argued that there are also considerable potential advantages for early movers. But this hypothesis lacks empirical evidence, which is due to the limitations of previous empirical research designs. On the one hand, early movers have not been precisely separated from pioneers and late movers. On the other hand, previous research designs often specified a monotone relationship between order of entry and a success variable. As a consequence, it was not possible to find an inverted u-shaped relationship supporting the early mover advantage hypothesis. In this study, authors propose ways to overcome these limitations. An empirical application to 12 pharmaceutical markets finds a surprising early mover advantage that contrasts with the conventional wisdom in this industry.

Abstract: Although there is a growing amount of theoretical literature, only limited attention has been allocated to empirically determine the relative influence of a broad set of strategic success factors of e-business companies across several industries. We concentrate on the impact of marketing strategies and chosen business models and differentiate between direct and indirect drivers on revenue and profitability in order to estimate the total effect of a certain strategy or business model. Based on a survey of 147 e-businesses from different industries we empirically test, with the help of seemingly unrelated regression models, the relative importance of the various strategy elements. Our estimation results show that business models where the firm profits from transactions (e.g., via fixed access or usage fees) and is able to sell pricy products and services are well suited to reach profitability. The by far most important element of the marketing strategy is the achieved customer satisfaction, which has a significant and strong effect on revenue, but only a moderate direct effect on profitability. Due to our modeling approach we find that the total elasticity of this element of the marketing strategy is driven by the indirect effect from revenue on profitability

Abstract: Service compositions enable users to realize their complex needs as a single request. Despite intensive research, especially in the area of business processes, web services and grids, an open and valid question is still how to manage service compositions in order to satisfy both functional and non-functional requirements as well as adapt to dynamic changes. This article describes an approach towards adaptive management of QoS aware service compositions. This approach integrates well known concepts and techniques and proposes various execution strategies based on dynamic selection and negotiation of services included in a service composition, contracting based on service level agreements, service enactment with flexible support for exception handling, monitoring of service level objectives, and profiling of execution data. An important element of the approach is an open architecture for adaptive service composition management. Its first prototypical implementation has been developed within an EU-funded Adaptive Service Grid project.
