Embrapa Technological Information: a bridge between research and society
This paper presents the efforts undertaken by the Brazilian Agricultural Research Corporation regarding Science and Technology information management, through one of its Decentralized Units, Embrapa Technological Information (Scientific and Technological Information Service', SCT). The major aim of SCT is to promote and improve the processes of scientific communication - information that feeds and that results from research activities - and of science and technology dissemination - information that results from research activities and that is directed to the general publi

Knowledge in development aid and healthcare: a comparative analysis
Effective delivery in the fields of development aid and healthcare relies on knowledge and its communication. Institutions, practitioners and the end-users are examined in these two fields as key actors in the production and communication of knowledge. Similarities and differences, and strengths and weaknesses of their approaches to knowledge are compared. Knowledge is shown to be an intrinsically political process in which institutions and practitioners play a critical role in its communication. Establishing a common background is essential to communicate knowledge effectively. The World Bank’s notion that knowledge is a simple commodity should be challenged
A Voice for the Voiceless: Peer-to-peer Mobile Phone Networks for a Community Radio Service
We propose a new application for mobile ad-hoc networks (MANETs) – community radio. We argue how MANETS help overcome important limitations in how community radio is currently operationalized. We identify critical design elements for a MANET based community radio service and propose a broad architecture for the same. We then investigate a most critical issue– the choice of the network wide broadcast protocol for the audio content. We identify desired characteristics of a community radio broadcasting service. We choose and evaluate eight popular broadcasting protocols on these characteristics, to find the protocols most suited for our application.
Rural small firms' website quality in transition and market economies
Purpose
– The purpose of this paper is to investigate website quality in rural firms in four countries, by using Gonzalez and Palacios's Web Assessment Index (WAI). There is an assertion in the literature that quality is lower amongst rural firms than urban firms, and lower amongst small firms than large firms. The disadvantages of lack of access to skills and economic peripherality in rural areas are attributed to this. Concurrently, there is reason to surmise that the websites of firms in transition economies may be higher quality than those in market economies. The paper aims to explore websites in distinct rural regions to investigate if variation occurs.
Design/methodology/approach
– To evaluate website quality the WAI was applied to a sample of 60 rural firms representing 15 each in Scotland, New Zealand, Southern Russia and Hunan Province in China. Analysis of the categorical data was performed using a variety of established methods.
Findings
– The WAI is of use in terms of website quality management. Additionally, comparisons between the quality of websites in the sample of small rural firms with those of large firms in previous studies support the contention that large firms generally have better quality websites. Results also illustrate that there are some differences in website quality between rural small businesses in the different locations. In particular, small rural firms in Hunan Province in China had websites of observable better quality than those elsewhere. The authors conclude that skills, knowledge and infrastructure have a bearing on the sophistication of small firms' websites.
Research limitations/implications
– Implications include that variation in the rural economy by region prevails as the rural economy is not, as often implied, a homogeneous concept.
Practical implications
– There are implications in terms of exploring the effects of regulation, culture and infrastructure on rural small to medium-sized enterprises (SMEs). The internet may indeed contribute to rural economies, but only insofar as it is facilitated by infrastructure and access to skills, and by culture and perceived usefulness by business owners.
Originality/value
– The paper contributes to the understanding of rural entrepreneurship as a heterogeneous concept by comparing practice in four distinct rural regions. It also adds weight to the emerging identification of exogenous factors as being at least as much a factor in determining the use of ICT in rural SMEs as endogenous motivations, skills and resources.

In Vivo Evaluation of the Secure Opportunistic Schemes Middleware using a Delay Tolerant Social Network
Over the past decade, online social networks (OSNs) such as Twitter and
Facebook have thrived and experienced rapid growth to over 1 billion users. A
major evolution would be to leverage the characteristics of OSNs to evaluate
the effectiveness of the many routing schemes developed by the research
community in real-world scenarios. In this paper, we showcase the Secure
Opportunistic Schemes (SOS) middleware which allows different routing schemes
to be easily implemented relieving the burden of security and connection
establishment. The feasibility of creating a delay tolerant social network is
demonstrated by using SOS to power AlleyOop Social, a secure delay tolerant
networking research platform that serves as a real-life mobile social
networking application for iOS devices. SOS and AlleyOop Social allow users to
interact, publish messages, and discover others that share common interests in
an intermittent network using Bluetooth, peer-to-peer WiFi, and infrastructure

Climate Services for Resilient Development (CSRD) Partnership’s work in Latin America
The Climate Services for Resilient Development (CSRD)
Partnership is a private-public collaboration led by USAID,
which aims to increase resilience to climate change in
developing countries through the development and
dissemination of climate services. The partnership
began with initial projects in three countries: Colombia,
Ethiopia, and Bangladesh. The International Center for
Tropical Agriculture (CIAT) was the lead organization for
the Colombian CSRD efforts – which then expanded to
encompass work in the whole Latin American region

Discussing international perspectives on Open Learning in Brazil: educational politics and pedagogical principles
This paper aims to present some of the new tendencies in Open Learning in the context of international online higher education. These tendencies work as a basis for a discussion of the role of e-learning in online higher education in Brazil. The use of open source technologies and the constant search for quality and innovative pedagogies in the teaching and learning process constitute a new trend in international distance education. The main concern nowadays seems to be with ‘quality’ and ‘widening participation’, which result in initiatives such as ‘Open Educational Resources’.
In Brazil, the creation of the Brazilian Open University (UAB) would appear to be consistent with these tendencies. The challenge now is to be able to set up a system that attends to national needs while being open to international tendencies. This paper aims to explore some of these issues, and also to present the most recent freeware technologies used for the purpose of enhancing open learning initiatives
