Virtual Architecture: Designing and Directing Curriculum-Based Telecomputing

Is it worth it, all this Internet stuff? Worth the time and energy it takes? Worth it because your students will learn more? Worth it because you\u27ll be a better teacher? The answer to these questions-yes and no-can be found in this readable, conversational, practical, and slyly revolutionary work. The author proposes that integrating computer-mediated technology into your classroom is well worth it if accomplished in a way that helps new and worthwhile things happen there. And then she shows you how to do just that. You\u27ll begin building with a flexible framework-clear, strong, and simple activity structures-that becomes your foundation for designing and implementing powerful curriculum-based telecomputing projects. Don\u27t expect a project directory, general reference, or manual. This is a book you\u27ll read from start to finish and be glad you did. It\u27s worth it

Holographic MIMO Communications: Theoretical Foundations, Enabling Technologies, and Future Directions

Future wireless systems are envisioned to create an endogenously holography-capable, intelligent, and programmable radio propagation environment, that will offer unprecedented capabilities for high spectral and energy efficiency, low latency, and massive connectivity. A potential and promising technology for supporting the expected extreme requirements of the sixth-generation (6G) communication systems is the concept of the holographic multiple-input multiple-output (HMIMO), which will actualize holographic radios with reasonable power consumption and fabrication cost. The HMIMO is facilitated by ultra-thin, extremely large, and nearly continuous surfaces that incorporate reconfigurable and sub-wavelength-spaced antennas and/or metamaterials. Such surfaces comprising dense electromagnetic (EM) excited elements are capable of recording and manipulating impinging fields with utmost flexibility and precision, as well as with reduced cost and power consumption, thereby shaping arbitrary-intended EM waves with high energy efficiency. The powerful EM processing capability of HMIMO opens up the possibility of wireless communications of holographic imaging level, paving the way for signal processing techniques realized in the EM-domain, possibly in conjunction with their digital-domain counterparts. However, in spite of the significant potential, the studies on HMIMO communications are still at an initial stage, its fundamental limits remain to be unveiled, and a certain number of critical technical challenges need to be addressed. In this survey, we present a comprehensive overview of the latest advances in the HMIMO communications paradigm, with a special focus on their physical aspects, their theoretical foundations, as well as the enabling technologies for HMIMO systems. We also compare the HMIMO with existing multi-antenna technologies, especially the massive MIMO, present various...Comment: double column, 58 page

Exploring knowledge broker influences on sharing and use of evidence for health policy and practice in low- and middle-income countries

Little is known about how intermediaries called knowledge brokers work in low- and middle-income countries to help move evidence into policy and practice to improve health outcomes. The aim of this PhD research project was to understand how knowledge brokers spread and mobilize evidence in multiple countries and regions in the context of an internationally funded global health program. It used case studies, interviews, and surveys of nearly 600 health professionals in more than 65 countries. Findings show knowledge brokers participating in the studies worked in multiple roles in healthcare systems and used their professional networks to help policymakers, healthcare providers, and others adapt evidence for use in the local context. They exhibited attributes such as a “can-do” spirit to overcome challenges in implementing evidence. Knowledge brokers were influenced in selecting evidence by having an opportunity to share it during their professional duties, how well the evidence fit their professional role, successes in using the evidence in similar contexts, and how well it fit the healthcare decision-making culture of the country. Initiatives to increase evidence uptake should consider strengthening the use of knowledge brokers in health organizations and building their capacity to work across countries and regions

Knowledge retention model for institutions of higher learning : a case of Kenya Methodist University (KeMU)

Kenya Methodist University (KeMU) is facing challenges like duplication of work due to lack of a central repository for knowledge retention, loss of knowledge through expertise leaving the institution without knowledge being captured and over reliance on a few known subject matter experts as others have not been identified. Utilising the Knowledge Retention Strategy framework, this study sought to assess knowledge retention practices at KeMU, with a view to entrench the culture of sharing knowledge. The ultimate aim of this study was to develop a model for knowledge retention at institutions of higher learning which KeMU could adopt. The study relied on mixed method research (MMR) with qualitative and quantitative data mixed at collection, analysis, discussion and reporting levels. The study triangulated data collection tools which encompassed a questionnaire, interview, observation and review of documents to collect data from 106 respondents and 11 heads of departments respectively. These two groups were purposively selected as they play a key role in knowledge retention at KeMU. The study disclosed a variety of informal knowledge retention practices but formal practices like: documented work processes; training and development for specific job tasks; orientation for general and job specific; knowledge repositories; communities of practice; knowledge retention policies; knowledge recovery initiatives; and human resources processes and practices for knowledge retention were lacking. Considering the value placed on the above list of lacking essential practices for knowledge retention, KeMU is indeed in dire need for a solution to help retain operational relevant knowledge. The study formulated a KR model for institutions of higher learning that would help KeMU leverage its knowledge assets. The study recommends that KeMU should work out a knowledge retention policy on how to implement the best knowledge retention practices. A further study on measuring KM in an academic institution is recommended.Information ScienceM. Inf

Food for Talk: Addressing barriers to communicating agricultural knowledge to subsistence farmers in Timor-Leste.

The International Fund for Agricultural Development has identified barriers to the sharing of knowledge with small farm holders as one of the key obstacles to increased food production in developing countries. The purpose of this research was to examine ways in which these barriers could be overcome in respect of subsistence farmers in Timor-Leste, a significant proportion of whom have low levels of literacy and poor access to conventional mass media channels. The first part of this research was concerned with how communication is best positioned in development projects. The researcher was contracted to draft a communication strategy for the agricultural project Seeds of Life, and to conduct communication training workshops for the project's staff. Neither the strategy nor the workshops were found to change thinking about communication within the project from what is known as the deficit model, which places a premium on communication outputs, to one more attuned to communication impacts. Despite the strategy and the workshops communication staff also continued to be viewed as mere service providers taking instruction from researchers and technical advisers rather than professionals in their own right with particular skills to bring to the challenge of sharing knowledge in the most appropriate ways. A longitudinal study was then undertaken of the interactions between these two groups within Seeds of Life. This consisted of interviews with staff members over a period of four years. This study found that communication staff on the one hand, and research scientists and technical advisers on the other, eventually achieved a more effective working relationship through processes designed to improve their cross-disciplinary communication. The study provides evidence in support of a model of project planning which focuses on how natural science and social science practitioners work together to produce fit-for-purpose communication initiatives rather than models that seek to determine communication approaches and techniques in advance. The research then trialed two ways of communicating with farmers across the language, literacy and educational spectrum in Timor-Leste. The first of these was participatory theatre; the second video animation capable of being shown on laptops, iPads and mobile devices. Both employed forms of entertainment-education to engage audiences with the informational content and both used illustration as the technique for sharing knowledge. These trials demonstrated considerable potential for both techniques to overcome barriers to agricultural science knowledge sharing in Timor-Leste and in similar challenging communication contexts
