Factors Affecting Knowledge Sharing in Virtual Learning Teams (VLTs) in Distance Education

This study asserts that knowledge sharing (a component of knowledge management) in distance education virtual learning teams (VLTs) is important for successful collaborative learning and that various factors characterizing person and environment can impact VLT members\u27 knowledge sharing behavior. Factors under the category of person are VLT members\u27 competencies for working on VLTs, and their learning goal orientation and performance goal orientation. Factors under VLT environment are social presence in the VLT, the VLT learning community, satisfaction with the VLT, task type, and instructor strategies. Knowledge sharing is defined as a behavior in which VLT members impart their expertise, insight, or understanding to other members in the VLT or to the entire team, intending for the recipients to have that knowledge in common with themselves, the sharers. The study used Bandura\u27s (1986) model of triadic reciprocal causation as a theoretical framework. The model is suitable for this research because it considers relationships between person, environment, and behavior. First, the study identified variables that are directly related to knowledge sharing. Next, the study validated those constructs. After the constructs had been validated, they were entered into a knowledge sharing measurement model. The study empirically tested a measurement model with five latent variables, taking into account the measurement error. Next, the study cross-validated the model with multiple groups drawn from the same sample. The sample consisted of data from 1,374 participants matriculated in graduate and undergraduate programs at an online university. The data were analyzed using split sample methodology, multiple regression analysis, and structural equation modeling techniques (factor analysis and latent variable structural equation modeling- SEM). The study\u27s findings suggest that there is a direct predictive relationship between knowledge sharing and competencies for working on VLTs, learning environment, social presence, task type, and mediating relationships for learning community, social presence, and task type in the knowledge sharing model. This study contributes to research, theory, and practice. It concludes by presenting a knowledge sharing model that can be reevaluated with distance education student populations at various kinds of distance education institutions

An Approach for Supporting Ad-hoc Modifications in Distributed Workflow Management Systems

Supporting enterprise-wide or even cross-organizational business processes is a characteristic challenge for any workflow management system (WfMS). Scalability at the presence of high loads as well as the capability to dynamically modify running workflow (WF) instances (e.g., to cope with exceptional situations) are essential requirements in this context. Should the latter one, in particular, not be met, the WfMS will not have the necessary flexibility to cover the wide range of process-oriented applications deployed in many organizations. Scalability and flexibility have, for the most part, been treated separately in the relevant literature thus far. Even though they are basic needs for a WfMS, the requirements related with them are totally different. To achieve satisfactory scalability, on the one hand, the system needs to be designed such that a workflow instance can be controlled by several WF servers that are as independent from each other as possible. Yet dynamic WF modifications, on the other hand, necessitate a (logical) central control instance which knows the current and global state of a WF instance. For the first time, this paper presents methods which allow ad-hoc modifications (e.g., to insert, delete, or shift steps) to be performed in a distributed WfMS; i.e., in a WfMS with partitioned WF execution graphs and distributed WF control. It is especially noteworthy that the system succeeds in realizing the full functionality as given in the central case while, at the same time, achieving extremely favorable behavior with respect to communication costs

Proceedings of the 2012 Workshop on Ambient Intelligence Infrastructures (WAmIi)

This is a technical report including the papers presented at the Workshop on Ambient Intelligence Infrastructures (WAmIi) that took place in conjunction with the International Joint Conference on Ambient Intelligence (AmI) in Pisa, Italy on November 13, 2012. The motivation for organizing the workshop was the wish to learn from past experience on Ambient Intelligence systems, and in particular, on the lessons learned on the system architecture of such systems. A significant number of European projects and other research have been performed, often with the goal of developing AmI technology to showcase AmI scenarios. We believe that for AmI to become further successfully accepted the system architecture is essential

A virtual-community-centric model for coordination in the South African public sector

Organizations face challenges constantly owing to limited resources. As such, to take advantage of new opportunities and to mitigate possible risks they look for new ways to collaborate, by sharing knowledge and competencies. Coordination among partners is critical in order to achieve success. The segmented South African public sector is no different. Driven by the desire to ensure proper service delivery in this sector, various government bodies and service providers play different roles towards the attainment of common goals. This is easier said than done, given the complexity of the distributed nature of the environment. Heterogeneity, autonomy, and the increasing need to collaborate provoke the need to develop an integrative and dynamic coordination support service system in the SA public sector. Thus, the research looks to theories/concepts and existing coordination practices to ground the process of development. To inform the design of the proposed artefact the research employs an interdisciplinary approach championed by coordination theory to review coordination-related theories and concepts. The effort accounts for coordination constructs that characterize and transform the problem and solution spaces. Thus, requirements are explicit towards identifying coordination breakdowns and their resolution. Furthermore, how coordination in a distributed environment is supported in practice is considered from a socio-technical perspective in an effort to account holistically for coordination support. Examining existing solutions identified shortcomings that, if addressed, can help to improve the solutions for coordination, which are often rigidly and narrowly defined. The research argues that introducing a mediating technological artefact conceived from a virtual community and service lenses can serve as a solution to the problem. By adopting a design-science research paradigm, the research develops a model as a primary artefact to support coordination from a collaboration standpoint. The suggestions from theory and practice and the unique case requirement identified through a novel case analysis framework form the basis of the model design. The proposed model support operation calls for an architecture which employs a design pattern that divides a complex whole into smaller, simpler parts, with the aim of reducing the system complexity. Four fundamental functions of the supporting architecture are introduced and discussed as they would support the operation and activities of the proposed collaboration lifecycle model geared towards streamlining coordination in a distributed environment. As part of the model development knowledge contributions are made in several ways. Firstly, an analytical instrument is presented that can be used by an enterprise architect or business analyst to study the coordination status quo of a collaborative activity in a distributed environment. Secondly, a lifecycle model is presented as meta-process model with activities that are geared towards streamlining the coordination of dynamic collaborative activities or projects. Thirdly, an architecture that will enable the technical virtual community-centric, context-aware environment that hosts the process-based operations is offered. Finally, the validation tool that represents the applied contribution to the research that promises possible adaptation for similar circumstances is presented. The artefacts contribute towards a design theory in IS research for the development and improvement of coordination support services in a distributed environment such as the South African public sector

E-government and digital inclusion

LEFIS organized a meeting in July 2007 in Jaca (Spain) to discuss the status and the perspectives of e-Government especially applied to the legal aspects of society. As it is known the potential benefits of e-Government are numerous and they include greater efficiency, improved public services, enhanced engagement with citizens. Yet progress has been relatively slow, particularly when compared with other sectors such as e-Commerce. From the presentations of some experiences focused in particular on digital divide, e-Participation, form of government, role of citizens, planning methodology in proposing solutions for citizens, the book highlights some problems and solutions to help overcome barriers
