Facilitating Collaboration
2017
This article explores the potential synergy between computer-supported collaborative learning (CSCL) and collaboration engineering (CE). Both areas pursue the goal of understanding how to manage interactions in collaborative groups to achieve shared understanding, reduce process losses, and improve performance. By analyzing the research in the two areas, the authors identify several topics where exchange of research findings would be of mutual benefit. For example, research on CE can inform collaboration script research on reducing learners' cognitive load, providing sufficient guidance on the use of tools, and specifying the instructor role during the collaborative learning process. Simila…
Uncertainties and Risks in the Implementation of an E-Learning Information Systems Project in a Higher-Learning Environment: Viewpoints from Estonia
2005
This paper investigates the sorts of risks and uncertainties inherent in implementing an e-learning information systems project in Estonia. The study uses a variation of the Delphi study in eliciting the risk factors or items from experienced top management professionals within the organisation. The main objective of the study is to identify the uncertainties or risks in the implementation of the systems, using the viewpoint of Estonia, which is an emerging economy. The findings of the work indicate that wrong development strategy, staff volatility, change in top management and lack of funding are amongst the top risk factors in implementing e-learning in Estonia. On the other hand, risks …
Raising Energy Saving Awareness Through Educational Software
2013
A study that I have conducted on a sample of 395 children aged 6 to 12, from both the urban and the rural environments, shows that an increasing number of them use computer related technologies. Today there are an increasing number of web sites that inform the user of different ways to save energy and to reduce energy consumption because it is only natural that the modern information society would go online to research such topics. The development of an educational application that is focused on teaching the children about energy saving is represented on a timeline. We conducted a study in which a number of 29 children, aged between 8 and 10, use this educational application and a questionn…
Coauthorship and institutional collaborations on cost-effectiveness analyses: a systematic network analysis
2012
BackgroundCost-Effectiveness Analysis (CEA) has been promoted as an important research methodology for determining the efficiency of healthcare technology and guiding medical decision-making. Our aim was to characterize the collaborative patterns of CEA conducted over the past two decades in Spain.Methods and findingsA systematic analysis was carried out with the information obtained through an updated comprehensive literature review and from reports of health technology assessment agencies. We identified CEAs with outcomes expressed as a time-based summary measure of population health (e.g. quality-adjusted life-years or disability-adjusted life-years), conducted in Spain and published bet…
The requisite match between internal resources and network ties to cope with knowledge scarcity
2020
PurposeThis paper aims to investigate the internationalization strategies of small and medium enterprises (SMEs), focusing on the interaction between network ties and “soft” internal resources at the foundation of knowledge management (KM). Specifically, it identifies the firms’ internal capabilities that affect KM strategies, and their collective influence on the degree of internationalization; verifies the influence of network ties on the internationalization process itself; and develops a conceptual “preliminary theoretical framework of SME internationalization capabilities and networks.”Design/methodology/approachThe primary research and analysis are based on a proportional stratified s…
Socio-technical innovation in community-based tourism organizations: A proposal for local development
2021
Abstract Socio-technical innovation is based on new patterns of interaction involving a set of new behaviors that have been legitimized in a given context. The approach of socio-technical innovation complements a purely technological innovation focus. However, studies of how to address social and environmental challenges under this approach are scarce. The aim of this paper is to identify the technical and social structures that underpin the socio-technical innovation system of community-based tourism organizations (CBTOs). This paper offers an in-depth case study of a specific type of collective property known as an “ejido”. Through this case study, the paper highlights the aspects that ha…
Using Social Networks to Enhance Customer Relationship Management
2013
International audience; In recent years, the Web has evolved into an exchange platform. Customer Relationship Management (CRM) must follow this evolution and connect CRM tools to social networks in order to place companies in the center of all the exchanges. We propose, in this article, a community detection approach that identi fies clusters of customers of a company using their explicit and implicit behaviour. Our contribution is the definition of a composite pro le that integrates various informations gathered from di erent applications, such as the information system of the company, the existing CRM, or Twitter. We de ne a similarity measure, between a user and a tag, that takes into ac…
Value networks in cloud computing
2011
PurposeThe purpose of this paper is to examine value networks in cloud computing. It demonstrates the kinds of value offered by such networks to firms within a given network, and considers how and why the network may change over time.Design/methodology/approachThe paper reports on a longitudinal case study, including a total of seven semi‐structured open‐ended interviews, conducted with five informants from the case firm.FindingsIt was found that cooperation in value networks provides not merely financial benefits, but also knowledge, among other intangible benefits. Value networks should be evaluated as a whole, since there may be indirect connections – i.e. the value comes not directly fr…
Towards a network-based view of effective entrepreneurial ecosystems
2021
AbstractWe conceptualize entrepreneurial ecosystems as fundamentally reliant on networks and explore how and under what conditions inter-organizational networks lead an entrepreneurial ecosystem to form and evolve. It is widely accepted that entrepreneurial ecosystems possess a variety of symbiotic relationships. Research has focused considerable efforts in refining the structure and content of resources found within these networked relationships. However, merely focusing on actor-level characterizations dilutes the notion that social relationships change and are complex. There has been little conceptual treatment of the behavioral and governance factors that underpin how quality interactio…
FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images
2019
Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…
