Abstract: Although consultants have long placed the use of research information at the centre of their activity, the extent that physicians use this information tends to vary widely. Despite this study and its recommendations, there is still a gap between the functions of a manager and the use of the associated information, while the decision-making procedures vary according to the organization in which they work. The cost of IT remains the largest barrier, while some current IT solutions are not user friendly and out-of-date, particularly for public hospitals in Greece. The knowledge management is concerned not only with the facts and figures of production, but also with the know-how of staff. The information needs protocol should not be referred only to those who comply with formal computer-based information systems, but also to those who take into account other informal information and its flow within the organization. In a field such as medicine, where out-of-date information may be positively dangerous, doctors make heavy use of journals and several texts from the web. The decision-making process is a complex approach, particularly in human diagnostic and therapeutic applications. Therefore, it is very important to set priorities in the sector of health information management and promote education and training on information and communication technology (ICT).
Abstract: This paper builds on the results of a 3-year long European project, the main aim of which was to deeply and sustainably transform teaching and learning practice in primary and secondary schools and higher education, by introducing Do it Yourself (DIY) philosophy in order to expand digital competence and foster students’ agency and collaborative learning. Three universities and three primary and secondary schools have been involved in a Collaborative Action Research (CAR) process in order to analyse their current institutional context and perceive needs, strengths and weaknesses; to undertake professional development activities and the design of DIYLabs; implement DIYLabs in the selected courses; and reflect upon ways of improving the institution’s performance. This paper offers a global vision of the research and implementation processes and the results achieved, from the perspective of the socio-economic dimensions involved in a project aiming to make a difference in teaching and learning to meet the challenges of a society highly permeated by digital technology (DT).
Abstract: There seems to be an inherent tension between wiki affordances—open boundaries, unconstrained editing, and transparency—and traditional knowledge management (KM) routines used in firms. The objective of this study is to investigate how users respond to these tensions during adoption of wiki technology at the workplace. The theoretical lens of sociomateriality highlights the manner in which routines and materiality (namely, technology) relate to one another, providing a useful conceptualization for our investigation. In particular, we adopt Leonardi’s theory of human and material imbrication, which stresses the importance of a worker’s past experiences with technology in determining his future adoption decisions. Extending Leonardi’s conceptualization, we suggest that out-of-work experiences are also influential. Namely, we argue that attitudes towards Wikipedia influence one’s response to wiki deployment in the workplace. Using an online survey containing four open-ended questions, we assessed the perceptions of employees towards wiki deployment. Results from our qualitative analysis of 1032 responses reveal five approaches users take in responding to the tensions between wiki affordances and existing KM routines, highlighting the effect of users’ dispositions towards Wikipedia. Our findings inform the sociomateriality literature and shed light on the challenges faced by organizations trying to adopt social media tools.
Abstract: Adoption of social media systems (SMS), proprietary microblogging platforms in particular, for the purposes of information sharing has been increasingly on the rise among corporations. While Twitter is the preferred microblogging tool by the general public, there is scant research to address its viability as a conduit to facilitate knowledge creation among corporate users. As a result, this conceptual paper explores seven crucial Twitter features and derives to seven propositions that demonstrate how microblogging can enable knowledge creation among employees within shared knowledge domain.
Abstract: A social circle is a category of strong social relationships, such as families, classmates and good friends and so on. The information diffusion among members of online social circles is frequent and credible. The research of users’ online social circles has become popular in recent years. Many scholars propose methods for detecting users’ online social circles. On the other hand, the social meanings and the tags of a social circle are also important for the analysis of a social circle. However, little work involves the tags discovery of social circles. This paper proposes an algorithm for social circle tag detection by multiple linear regression. The model solves the data sparse problem of tags in social circles and successfully combines different categories of features in social circles. We also redmap the concept of the social circle into "reference circles" of an academic paper. We evaluate our method in datasets of both Facebook and Microsoft Academic Search, and prove that it is more effective than other relevant methods.
Abstract: In a Mobile Wireless Sensor Mesh Network (MWSMN), based on the IEEE 802.15.4 standard, low power consumption is vitally important since the network devices are mostly battery driven. This is especially true for devices dependent on small form factors, such as those used in wireless sensor network. This paper proposes four new approaches to reduce the Back-Off Time in ZigBee standard in order to minimize the collisions caused by transmission between neighbouring nodes within the mesh network. The four alternate algorithms for the Back-Off Time calculation are compared to the ZigBee standard Back-Off Time algorithm regarding their energy needs using the simulation suite OPNET Modeler. To study the behaviour of the parameters of all algorithms in all scenarios, the statistical Analysis of Variance (ANOVA) has been used and it shows that the null hypotheses are rejected except for one case. The results show that the two passive algorithms Tabu Search and Simulated Annealing search techniques are suitable for battery-driven, energy-sensible networks. The Ant Colony Optimization (ACO) approaches increase throughput and reduce the packet loss but cost more in terms of energy due to the implementation of additional control packets. To the best of the authors’ knowledge, this is the first approach for MWSMN that uses the Swarm Intelligence technique and the search solution algorithm for the Back-Off Time optimization.
