How Can Information Systems Strengthen Virtual Communities? Perspective of Media Richness Theory

Media richness was known as important in designing information and communication technologies (ICTs). However, no studies have examined how the four aspects of media richness could help fuel users’ commitment to virtual communities, indicating a gap. Hence, we use media richness theory and initiate to use its key elements (i.e., message certainty and message unequivocality) to construct a research framework. We collected 1,971 responses from virtual communities in online games and used structural equation modeling for testing the hypotheses. We found that immediate feedback and personal focus are positively related to message certainty and message unequivocality that are further positively related to network convergence and interdependence, thus contributing to commitment to virtual communities. This study is the first formally incorporating and testing the key elements of media richness, i.e., message certainty and message unequivocality, and examining how media richness of information systems could fuel users’ commitment to virtual communities

Forms of organizing: What is new and why?

This paper aims to further our understanding of new forms of organizing by asking and answering two related questions: What is new in forms of organizing? and Why is it so? It starts by examining the main forces that lead to the emergence and diffusion of new organizational arrangements, distinguishing between objective and subjective factors and pointing out the interplay between the two. Elaborating on these two groups of factors, the paper introduces two dimensions ‹flexibility and openness‹ on which a contingency analysis of new forms of organizing and a classification are built. Flexibility is associated with the question «How fast does the organization as a whole have to learn?», while openness is intended to measure the need for knowledge integration and the location of relevant knowledge. Having outlined the main trends in the development of organizational arrangements, the paper looks at some of the implications. The use of information and communication technologies, knowledge management, changes in human resource practices and social contract, and changes in management roles and careers are all seen as consequences of a new quest for openness and flexibility. All these considerations lead to the conclusion that, nowadays, changes in organizational patterns are radical, calling for a paradigm change that will facilitate, in a holistic manner, the adjustments that are needed in order to build and manage these organizations. Like any paradigm change, this requires a change in the mindset of the agents involved, especially the decision-makers.new forms of organizing; new organizational arrangements;

The business model: Theoretical roots, recent developments, and future research

The paper provides a broad and multifaceted review of the received literature on business models, in which we attempt to explore the origin of the construct and to examine the business model concept through multiple disciplinary and subject-matter lenses. The review reveals that scholars do not agree on what a business model is, and that the literature is developing largely in silos, according to the phenomena of interest to the respective researchers. However, we also found some emerging common ground among students of business models. Specifically, i) the business model is emerging as a new unit of analysis; ii) business models emphasize a system-level, holistic approach towards explaining how firms do business; iii) organizational activities play an important role in the various conceptualizations of business models that have been proposed, and iv) business models seek not only to explain the ways in which value is captured but also how it is created. These emerging themes could serve as important catalysts towards a more unified study of business models.Business model; strategy; technology management; innovation; literature review;

Networks, Hierarchies, and Markets: Aggregating Collective Problem Solving in Social Systems

How do decentralized systems collectively solve problems? Here we explore the interplay among three canonical forms of collective organization--markets, networks, and hierarchies--in aggregating decentralized problem solving. We examine these constructs in the context of how the offices of members of Congress individually and collectively wrestle with the Internet, and, in particular, their use of official websites. Each office is simultaneously making decisions about how to utilize their website. These decisions are only partially independent, where offices are looking at each other for lessons, following the same directives from above about what to do with the websites, and confront the same array of potential vendors to produce their website. Here we present the initial results from interviews with 99 Congressional offices and related survey of 100 offices about their decisions regarding how to use official Member websites. Strikingly, we find that there are relatively few efforts by offices to evaluate what constituents want or like on their websites. Further, we find that diffusion occurs at the "tip of the iceberg": offices often look at each others' websites (which are publicly visible), but rarely talk to each other about their experiences or how they manage what is on their websites (which are not publicly visible). We also find that there are important market drivers of what is on websites, with the emergence of a small industry of companies seeking to serve the 440 Members. Hierarchical influences--through the House and through the party conferences--also constrain and subsidize certain practices.

Comparative Regionalism - A New Research Agenda

After the end of the Cold War, students of International Relations observed an expansion of inter-state activities at the regional level. Regional and sub-regional groupings appeared to gain momentum as the way in which countries cooperate and should cooperate to pursue peace, stability, wealth and social justice. The surge and resurgence of regionalism has triggered the proliferation of concepts and approaches. The focus of this paper will be on processes and structures of state-led regionalism driven by the delegation of policies and political authority to regional institutions. Based on this understanding of regionalism, the existing literature will be reviewed with regard to three general questions. These questions do not only require research across regions but also allow developing a common research agenda to accumulate knowledge generated about specific regions. First, what are the outcomes of regionalism? How can we describe and compare the results of the delegation of policies and political authority? Second, what are the drivers of regionalism? Why do some governments choose to delegate policies and political authority while others do not? Finally, what are the internal effects of regionalism? How does the delegation of policies and political authority impact back on the domestic structures of the states involved?regional development; Europeanization; Europeanization

Internet Predictions

Theorizing Regionalism: Cooperation, Integration, and Governance

Introduction: The end of the Cold War saw a surge in regionalism. While the number of preferential trading agreements (PTA) exploded (Mansfield and Pevehouse 2013), long-standing regional organizations, such as the Association of Southeast Asian Nations (ASEAN) or the Economic Community of West African States (ECOWAS), experienced the delegation of more political authority and policy competencies in the past two decades (Börzel 2013). These two trends of more and deeper regionalism, respectively, are often attributed to processes of diffusion or interdependent decision-making. Regional cooperation and integration spread across time and space once the constraints of geopolitics had ceased to exist (Risse in this volume)

A text categorisation tool for open source communities based on semantic analysis

Open source software (OSS) projects are supported by communities interacting through software repositories and mailing lists. Thousands of contributors participate in the development of the projects although they rarely meet each other. The result is a huge archived repository with thousands of questions, answers and contributions usually difficult to explore. We propose a tool based on semantic analysis for both performing an automatic knowledge discovery and a categorisation of the content of mailing lists repositories. Semantic analysis is a practical method for extracting and inferring relations of words in passages of discourse, producing measures of relations among words or passages that are well correlated with semantic similarity. The objective of this article is two-fold: (1) to develop a text categorisation tool based on indexing terms and semantic annotation, and (2) to apply the developed tool to extract the main dimensions related to knowledge sharing activities in virtual communities. Debian Linux ports to embedded processors are used as a case study to accomplish the proposed double objectiv
