Digital libraries (DL) have had a tremendous impact on improving the accessibility of scientific and academic publications. In developing countries, they seem to be the great hope, due to the serious existing problems with the traditional publishing and distribution mechanisms and to the potential they have on enabling access to a great panoply of publications. Moreover, accessing digital libraries over mobile devices has the potential of reaching a broader community of users and on helping to bridge the digital divide, since there are very reduced computer and Internet penetration rates in these countries, along with a higher mobile phone usage. For developed countries, accessing digital libraries on the go might also bring important added value. This paper features an analysis of the major issues related to making digital libraries accessible over mobile devices. A specific study on the possibility of using mobile digital libraries in a developing country context is also presented along with a proposal for making DSpace based digital libraries accessible over mobile phones.

Digital libraries (DL) are seen as the hope for developing countries in their struggle to access scientific and academic publications. However, building such libraries in developing countries is a real challenge. These countries usually face several difficulties, such as low computer and Internet penetration rates, poor ICT infrastructure, lack of qualified human resources, lack of financial resources, etc. Thus, it is imperative finding alternative mechanisms of building DL that best fit the specificities of these countries. This paper presents the process used for building a digital library at the University Jean Piaget of Cape Verde, created in a context of scarce access to printed materials and serious difficulties in accessing ICT resources. This paper also presents the challenges, the solutions and the adopted methodological framework.

O aumento da competitividade das empresas caboverdeanas impõe-se sobretudo por causa do momento histórico que particularmente o país atravessa. A graduação para país de rendimento médio, a adesão à Organização Mundial de Comércio e o estatuto de parceria especial com a União Europeia constituem razões de grande vulto para as empresas nacionais e outras que empreendem no mercado caboverdeano, definirem eficazmente e eficientemente os seus processos organizacionais de forma a atingirem patamares de produtividade e performance aos níveis internacionais. A envolvente externa às empresas caboverdeanas tem sido alvo de alterações profundas com a globalização dos mercados e o novo paradigma de economia baseada no conhecimento. Para que as empresas mantenham posições competitivas são muitos os desafios que terão que superar. Inexoravelmente, terão que reorganizar e redefinir os seus processos de negócio e suas estratégias de forma coerente. Os SI/TI constituem o factor potencial de reorganização e modernização, a alavanca de diferenciação competitiva e da concretização de negócios e resultados adicionais. O objectivo deste trabalho é o desenvolvimento e a validação de uma metodologia de enquadramento, análise e avaliação de investimentos em SI/TI. O procedimento proposto é fundamentado pela literatura e nas práticas das empresas cabo-verdianas e visa apoiar as empresas a atingirem estágios de performance e produtividade elevados, decorrentes da utilização optimizada dos recursos oferecidos pelos SI/TI. Porque elevadas somas de recursos financeiros são investidos em Sistemas e Tecnologias de Informação e nem todos os benefícios associados são quantificáveis e dado que os riscos associados são elevados, propõe-se com este trabalho um procedimento metodológico de apoio às empresas. Esta metodologia simplificada de análise de investimentos em Sistemas e Tecnologias da Informação propõe uma abordagem científica, sólida e objectiva de avaliação de investimentos em SI/TI, visando propiciar incremento do valor acrescentado dos produtos e/ou serviços das empresas. Os resultados obtidos a partir das análises quantitativas e qualitativas elaboradas permitem retratar a prática das empresas caboverdeanas no domínio de análise e avaliação de investimentos em SI/TI e gerar inferências importantes sobre o comportamento dos responsáveis empresariais e de SI/TI. The increase in competition by the Capeverdean companies is taking place mainly because of the historic moment the country is going through. The recent nomination of Cape Verde as a medium development country, the adhesion to the WCO (World Commerce Organization) and the special partnership with the European Union are relevant reasons for the national companies and others that operate in the Capeverdean market to define efficiently their organizational processes in order to reach levels of productivity and performance comparable to the international ones. The external component of the Capeverdean companies has been undergoing deep changes with market globalization and with the new economic paradigma based on kowledge. In order to maintain their competitive position there are many challenges to overcome. Surely and steadily, they will have to reorganize and redefine their business processes and strategies in a coherent way. The IS/IT (information systems / information technologies) constitute the potential factor of reorganization and modernization, the boost-lever that will produce competitive diferentiation and concretization of businesses and additional results. The main goal of this work is development and validation of a methology of insertion, analysis and evaluation of investments in the IS/IT. The proposed procedure is fundamented by the literature and practice of the Capeverdian companies, and aims at supporting these companies so that they can reach high stages of performance and productivity due to the correct use of the resources offered by the IS/IT. As high amounts of financial resources are invested in Information Systems and Tehnologies, and because of the fact that not all associated benefits may be quantified, and since the associated risks are high, with this work we propose a methodological procedure to support these companies. This simplified analysis methodology in Information and Technologies Systems proposes a sound and objective scientific approach to evaluate investments in IS/IT aiming at providing an increase of the added value of the products and/or services supplied by these companies. The incoming results from the quantitative and qualitative analyses made will allow portraying the practice of the capeverdean companies in the domain of analysis and evaluation of investments in IS/IT and generating important inferences on the behaviour of the executives and IS/IT.
