    Abstract-The design of efficient information dissemination mechanism is a challenging problem in large-scale network with respect to the number of messages and termination time. In this paper, advertisement and searching -the two basic ingredients of information dissemination -are investigated and certain criteria are proposed with respect to the correctness, promptness and fairness of the approach. Based on the complementarity of both advertisement and searching, the aforementioned criteria can be satisfied under certain conditions, which form the baseline of design principles for efficient information dissemination, as analytically -also using numerical results -is investigated here

    Mobile Computing in Digital Ecosystems: Design Issues and Challenges

    Full text link
    In this paper we argue that the set of wireless, mobile devices (e.g., portable telephones, tablet PCs, GPS navigators, media players) commonly used by human users enables the construction of what we term a digital ecosystem, i.e., an ecosystem constructed out of so-called digital organisms (see below), that can foster the development of novel distributed services. In this context, a human user equipped with his/her own mobile devices, can be though of as a digital organism (DO), a subsystem characterized by a set of peculiar features and resources it can offer to the rest of the ecosystem for use from its peer DOs. The internal organization of the DO must address issues of management of its own resources, including power consumption. Inside the DO and among DOs, peer-to-peer interaction mechanisms can be conveniently deployed to favor resource sharing and data dissemination. Throughout this paper, we show that most of the solutions and technologies needed to construct a digital ecosystem are already available. What is still missing is a framework (i.e., mechanisms, protocols, services) that can support effectively the integration and cooperation of these technologies. In addition, in the following we show that that framework can be implemented as a middleware subsystem that enables novel and ubiquitous forms of computation and communication. Finally, in order to illustrate the effectiveness of our approach, we introduce some experimental results we have obtained from preliminary implementations of (parts of) that subsystem.Comment: Proceedings of the 7th International wireless Communications and Mobile Computing conference (IWCMC-2011), Emergency Management: Communication and Computing Platforms Worksho

    Horizontal Violence Effect on Nurse Retention

    Get PDF
    Horizontal violence is known by a variety of terms such as lateral violence, bullying, and incivility. Christie and Jones (2014) describe lateral violence as a problem in nursing where a behavior is demonstrated through harmful actions that occur between nurses. Studies have revealed how horizontal violence affects nurse retention. Horizontal violence is a relevant issue in the healthcare community, yet often goes undiscussed. Walrafen (2012) explains that an outcome of horizontal violence in nursing is directly proportional to a decrease in retention of nurses. Sherman (2012) proclaimed that nurses who are subjected to horizontal violence have low self-esteem, depression, excessive sick leave, and poor morale. As Wilson (2011) identified nurses, who witness or experience horizontal violence have an increased desire to leave the organization where the bullying takes place. Horizontal violence is a pervasive source of occupational stress with physical, psychological, and organizational consequences (Hauge, et al, 2010). Roy (2007) describes this as an unkind, discourteous manner in which nurses relate to their colleagues. As nurses seek to perform their daily tasks, other co-workers may embarrass them for their lack of knowledge, tease them as they participate in informal cliques, or demean them for their technique (Bakker, 2012). Creating excuses, taunting, and refusing to share information, nursing education or knowledge are examples of horizontal violence (Ball, 1996)

    Sensitivity analysis in a scoping review on police accountability : assessing the feasibility of reporting criteria in mixed studies reviews

    Get PDF
    In this paper, we report on the findings of a sensitivity analysis that was carried out within a previously conducted scoping review, hoping to contribute to the ongoing debate about how to assess the quality of research in mixed methods reviews. Previous sensitivity analyses mainly concluded that the exclusion of inadequately reported or lower quality studies did not have a significant effect on the results of the synthesis. In this study, we conducted a sensitivity analysis on the basis of reporting criteria with the aims of analysing its impact on the synthesis results and assessing its feasibility. Contrary to some previous studies, our analysis showed that the exclusion of inadequately reported studies had an impact on the results of the thematic synthesis. Initially, we also sought to propose a refinement of reporting criteria based on the literature and our own experiences. In this way, we aimed to facilitate the assessment of reporting criteria and enhance its consistency. However, based on the results of our sensitivity analysis, we opted not to make such a refinement since many publications included in this analysis did not sufficiently report on the methodology. As such, a refinement would not be useful considering that researchers would be unable to assess these (sub-)criteria

    Overview and Analysis of Practices with Open Educational Resources in Adult Education in Europe

    OER4Adults aimed to provide an overview of Open Educational Practices in adult learning in Europe, identifying enablers and barriers to successful implementation of practices with OER. The project was conducted in 2012-2013 by a team from the Caledonian Academy, Glasgow Caledonian University, funded by The Institute for Prospective Technological Studies (IPTS). The project drew on data from four main sources: • OER4Adults inventory of over 150 OER initiatives relevant to adult learning in Europe • Responses from the leaders of 36 OER initiatives to a detailed SWOT survey • Responses from 89 lifelong learners and adult educators to a short poll • The Vision Papers on Open Education 2030: Lifelong Learning published by IPTS Interpretation was informed by interviews with OER and adult education experts, discussion at the IPTS Foresight Workshop on Open Education and Lifelong Learning 2030, and evaluation of the UKOER programme. Analysis revealed 6 tensions that drive developing practices around OER in adult learning as well 6 summary recommendations for the further development of such practices

    Training Competences in Industrial Risk Prevention with Lego® Serious Play®: A Case Study

    Get PDF
    This paper proposes the use of the Lego® Serious Play® (LSP) methodology as a facilitating tool for the introduction of competences for Industrial Risk Prevention by engineering students from the industrial branch (electrical, electronic, mechanical and technological engineering), presenting the results obtained in the Universities of Cadiz and Seville in the academic years 2017–2019. Current Spanish legislation does not reserve any special legal attribution, nor does it require specific competence in occupational risk prevention for the regulated profession of a technical industrial engineer (Order CIN 351:2009), and only does so in a generic way for that of an industrial engineer (Order CIN 311:2009). However, these universities consider the training in occupational health and safety for these future graduates as an essential objective in order to develop them for their careers in the industry. The approach is based on a series of challenges proposed (risk assessments, safety inspections, accident investigations and fire protection measures, among others), thanks to the use of “gamification” dynamics with Lego® Serious Play®. In order to carry the training out, a set of specific variables (industrial sector, legal and regulatory framework, business organization and production system), and transversal ones (leadership, teamwork, critical thinking and communication), are incorporated. Through group models, it is possible to identify dangerous situations, establish causes, share and discuss alternative proposals and analyze the economic, environmental and organizational impact of the technical solutions studied, as well as take the appropriate decisions, in a creative, stimulating, inclusive and innovative context. In this way, the theoretical knowledge which is acquired is applied to improve safety and health at work and foster the prevention of occupational risks, promoting the commitment, effort, motivation and proactive participation of the student teams.Spanish Ministry of Science, Innovation and Universities / European Social Fund: Ramón y Cajal contract (RYC-2017-22222
