An Extended Model of Knowledge-Flow Dynamics

The modern enterprise depends upon timely and effective flows of knowledge through its organizations for success. But knowledge is not evenly distributed through the enterprise, and a dearth of information systems is available to enable such timely and effective flows. Further, the few theoretical knowledge-flow models available have not yet been developed to a point where they can effectively inform the design of information systems and business processes to support knowledge flow in the enterprise. A survey of current practice shows that such system and process design is accomplished principally by trial and error, one of the least effective approaches known. The research described in this article builds upon and extends current theory about knowledge flow. It focuses in particular on investigating flow dynamics to inform the design of information systems and business processes to enhance the flow of knowledge through the enterprise. Leveraging the good understanding of flows in other domains, we strive to extend theory that can lead to devices of considerable utility in the enterprise knowledge domain. The result is a four-dimensional, dynamic model that can be used to classify and visualize a diversity of knowledge-flow patterns through the enterprise. These patterns can, in turn, be analyzed to inform the design of useful information systems and business processes. The implications of this dynamic model are explored and a number of hypotheses are generated to motivate and guide future research into the phenomenology of knowledge flow

Improving content management - a semantic approach

Public administration institutions - as well as citizens and businesses - have to meet challenges of the constantly changing business and legal environment. The complexity and quantity of information to be faced with by these actors is increasing at an alarming rate. Research and development projects must turn to the development of innovative, modern technologies which enable citizens and businesses to access, understand and apply complex information easily. Ontology-based content management systems can contribute to the improvement of quality and effectiveness of significant processes, requiring the application of complex information, within the public administration or in a corporation. Compared to traditional content management systems, these systems can support further functions, such as semantic enabled search, explication of relations between documents, drafting of new documents, and version management, as well. Ontologies, in addition to the definition of concepts, support the most detailed and complete exploration of semantic relations between the concepts of a given domain

Collaborative explicit plasticity framework: a conceptual scheme for the generation of plastic and group-aware user interfaces

The advent of new advances in mobile computing has changed the manner we do our daily work, even enabling us to perform collaborative activities. However, current groupware approaches do not offer an integrating and efficient solution that jointly tackles the flexibility and heterogeneity inherent to mobility as well as the awareness aspects intrinsic to collaborative environments. Issues related to the diversity of contexts of use are collected under the term plasticity. A great amount of tools have emerged offering a solution to some of these issues, although always focused on individual scenarios. We are working on reusing and specializing some already existing plasticity tools to the groupware design. The aim is to offer the benefits from plasticity and awareness jointly, trying to reach a real collaboration and a deeper understanding of multi-environment groupware scenarios. In particular, this paper presents a conceptual framework aimed at being a reference for the generation of plastic User Interfaces for collaborative environments in a systematic and comprehensive way. Starting from a previous conceptual framework for individual environments, inspired on the model-based approach, we introduce specific components and considerations related to groupware

Connecting for a Social Good: A Multi-level Analysis of a Nascent Online Community

Online communities (OCs) such as Wikipedia have the potential to transform our global society and economy. Building and sustaining OCs, however, appears to be rather complex. Indeed, most OCs fail early on. The extant OC literature cannot fully explain this phenomenon. This thesis is thus motivated by the increasing importance of OCs and the unsolved complexities regarding building and sustaining them. In particular, it aims to answer the research question of how nascent OCs evolve and what the influences are on this evolution. To this end, it examines a longitudinal 34-months long case study of AshokaHub, a nascent global OC of social entrepreneurs, combining interview data with qualitative and quantitative data from the AshokaHub platform. Despite favourable conditions at AshokaHub’s launch and a re-launch with new functionality and curation strategies, user contributions remained limited. Drawing on the OC and social entrepreneurship literatures as well as the theories of affordances, technological frames of reference and groupware adoption, this thesis develops a multi-level model to address the research question. This model theorizes the evolution of nascent OCs and the influence of context and materiality on this evolution. It highlights that OC evolution happens as users across different social worlds within the OC continuously adopt and change their ways of using it. It also highlights that, on an individual user level, this OC evolution happens in a recursive process of framing, affordance perception and affordance actualisation that influences and is influenced by the material characteristics of the OC’s technological platform and is shaped by the OC’s context. This thesis thus contributes to the OC literature by providing insight into how nascent OCs evolve and what influences this evolution. In addition, it contributes to affordance theory by introducing the concept of a collaborative OC affordances. This concept aims to explain how collaborative affordances emerge and evolve on OCs given the generative nature of their underlying technological platforms. These findings have managerial implications as well. Good practices are identified that can support the successful start of an OC. This is complemented with a discussion on how to be situationally aware of the unpredictable evolution of an OC after its start
