Since 2004, educational videoconferences have been held in Brazil for paediatric radiologists in training. The RUTE network has been used, a high-speed national research and education network. Twelve videoconferences were recorded by the Health Channel and transformed into TV programmes, both for conventional broadcast and for access via the Internet. Between October 2007 and December 2009 the Health Channel website registered 2378 hits. Our experience suggests that for successful recording of multipoint videoconferences, four areas are important: (1) a pre-planned script is required, for both physicians and film-makers; (2) particular care is necessary when editing the audiovisual material; (3) the audio and video equipment requires careful adjustment to preserve clinical discussions and the quality of radiology images; (4) to produce a product suitable for both TV sets and computer devices, the master tape needs to be encoded in low resolution digital video formats for Internet media (wmv and rm format for streaming, and compressed zip files for downloading) and MPEG format for DVDs.

National Research and Education Network organizations (NRENs) provide advanced information and communication technology (ICT) services for the academic community of their country. Their focus is often on providing affordable high speed bandwidth amongst their members and to other research networks, but NRENs also provide other advanced services such as electronic repositories, educational environments and supercomputing facilities. Higher Education and Research institutions have to play an active role in the transformation to the “Knowledge Society”. A recent (2010) report of the International Telecommunication Union has identified NRENs as important vehicles in reaching the goals of the World Summit of the Information Society. It is also demonstrated that the Central Asian countries score very low in the Networked Readiness Indices of the World Economic Forum, including areas where strong NRENs could improve the status quo. NRENs therefore have a role that is also important for the nation itself and therefore claims for government support are legitimate. About 62% of the countries of the world already have an NREN and there are four characteristics that are common to these NRENs. In nearly all of the cases the NREN is a not-for-profit organization that not only serves the academic community, but is also owned by the same community. Four out of five Central Asian countries have an active NREN and these NRENs all participate in the EC funded CAREN project that aims to set up a sustainable regional network for the academic communities in the participating countries. Today, the Central Asian Research and Education Network (CAREN) is upgrading the ancient Silk Road to a 21st-century high-speed internet highway for research and educational institutions through the region. Operational since July 2010, CAREN currently interconnects scientists and students from Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan.

For several years, National Park Service scientists, historians, and educators have been working with National Science Foundation-funded High Performance Wireless Research and Education Network (HPWREN) researchers on developing, implementing, and evaluating Live Interactive Virtual Explorations (LIVE) at several sites. The LIVE activities utilize computers with headsets and microphones to link National Park Service sites with an array of audiences. The two case studies in this paper examine the effectiveness of LIVE activities that allow Washington, DC, inner-city youth to explore two hard-to-reach National Park Service sites: Knife River Indian Villages National Historic Site in North Dakota and the Hawaii Volcanoes National Park.

For the past decade, researchers affiliated with the National Science Foundation-funded High Performance Wireless Research and Education Network (HPWREN) have been working with Native American education communities on an array of Internet-enabled activities, including the Live Interactive Virtual Explorations (LIVE) pilot project. One of the communities involved with the pilot LIVE project is the Pala Native American Learning Center, which is located in rural San Diego County, California. This paper discusses five case studies encompassing LIVE activities between Pala tribal community members and field scientists/educators throughout southern California. Using laptops equipped with off-the-shelf accessories and freeware, the five pilot case studies demonstrate the advantages and disadvantages of utilizing the LIVE concept for real-time distance education programs at rural Native American communities.

Objectives: Depression is a risk factor for stroke. There is a knowledge gap on the predictors of prestroke depression in stroke survivors living in low- and middle-income countries (LMICs). We estimated prevalence and predictors of prestroke depression, as well as its association with poststroke depression (PSD) in the largest study of stroke in Africa. Methods: We evaluated information collected as part of the Stroke Investigative Research and Education Network (SIREN) study, a multicentre, case-control study conducted at 15 sites in Ghana and Nigeria. Prestroke depression status was ascertained in stroke survivors using a validated self-report tool, while PSD was assessed using a stroke specific screening tool for depression (“HRQOLISP-E”). Independent associations were investigated using complementary log-log regression and binary logit models. Results: Among 1,977 participants, prestroke depression was found in 141 (7.1%). In multivariate analyses, prestroke depression was significantly associated with tachycardia (OR = 2.22, 95% CI = 1.37-3.56) and low consumption of green leafy vegetables (OR = 1.91, 95% CI = 1.12-3.24). Forty-one (29.1%) of the prestroke depression sub-sample developed PSD. However, prestroke depression was not significantly associated with PSD. Conclusion: The findings should energize before-the-stroke identification and prioritization of limited treatment resources in LMICs to persons with depression who have multiple, additional, risks of stroke.
