The nature of operation of Thin Client computing makes their performance to be affected by both the quality of the network and the terminals. For the past few years, there are few analyses on the performance of Thin Clients that can produce reliable, valid, and up-to-date results collected in a well designed and evaluated experiment based research. This paper analyses the performance of Thin Clients through experiment based research. The approach is to use benchmark application which is designed specifically for measurement of desktop computers by inserting delays in the visual elements of such benchmark application. In this technique, packet's behavior is measured on the network as the application is executed from the server to a Thin Client. The analysis through measurements of the performance shows that the improvement of computer processing power has a lot of performance metrics and comparing the trend with the results collected nearly seven years ago by previous researchers. Moreover, the bandwidth is found to be the main bottleneck for the performance of Thin Clients while the CPU is of less concern. © 2012 IEEE. Source

The success of implementing information and communication technologies for development (ICT4D) requires an informed understanding of the context of application. This helps to inform decision making during identification, planning, and evaluation of ICT projects. In the African context, this is of paramount importance. However, empirical studies regarding ICT4D in Africa are still limited. This study aimed at identifying issues underlying the implementation of ICT4D in Tanzania. Specifically, it focused at identifying key priorities on ICT4D, facilitators, and challenges facing ICT4D implementation in Tanzania. The study also attempts to suggest possible measures to be taken to facilitate the progress of ICT4D for next 10 years. The results show that it is imperative to streamline ICT into the areas of i) Production and service provision ii) government iii) Health iv) Education, v)Business, and vi) the growth of SMEs. This is facilitated by i) Tax relief in ICT equipment, particularly computers and peripherals, ii) availability of low cost ICTs, iii) supportive social infrastructure, and iv) Government commitment. On the other hand, ICT4D in Tanzania is challenged by i) unsupportive connectivity infrastructure, ii) inadequate content quality, iii) unsupportive organisational issues such as policies, laws, and established systems and procedures, and iv) people related issues including inadequate ICT skills, mindset, and awareness. We observe that successful implementation of ICT4D in Tanzania is possible if facilitators can be exploited and challenges addressed. Specific issues that can be addressed are i) improving ICT connectivity, ii) enhancing content quality, iii) addressing leadership and organisational inertia, iv) emphasising on ICT effective strategic planning for ICT, v) enhancing ICT skills, awareness and mindset, and vi) cultivating innovative the culture at organisation level.

This study investigates the causal links between CO2 (carbon dioxide) emissions, energy consumption, economic development and FDI (foreign direct investment) in six Sub Saharan African countries: the Republic of the Congo, the DRC (Democratic Republic of the Congo), Kenya, South Africa, Zambia and Zimbabwe. The results based on an autoregressive distributed lag model imply that the variables move together in the long run (cointegration) in all of the countries. The results also support the environmental Kuznets curve hypothesis in the cases of DRC, Kenya and Zimbabwe. Moreover, FDI appears to increase CO2 emissions in some of the countries, while the opposite impact can be observed in others. The most common unidirectional Granger causality relationships run from the other variables to CO2 emissions, with different variables Granger causing CO2 emissions in different countries, and from GDP (gross domestic product) to FDI. Granger causality running to CO2 emissions appears more likely in the countries where the evidence supports the environmental Kuznets curve hypothesis. Otherwise, the causality relationships vary greatly between the countries, making it impossible to give any universal policy recommendations. © 2014 Elsevier Ltd. Source

In this paper we investigate students' preparedness towards using Social Networks and Internet-enabled mobile devices for learning and propose requirements that need to be met before higher learning institutions can embrace these two technologies for learning. To achieve this we conducted a survey in higher learning institutions in Tanzania. We looked at students' possession of Internet-enabled mobile devices, affordability of the Internet, level of competency and experience in operating mobile devices and using Social Networks. We also assessed time that students spend on social networking sites. In conclusion, the survey reveals that students in higher learning institutions are almost ready in terms of infrastructure, experience, and competence needed for operating mobile devices for learning, hence making these tools appropriate to be used as supplementary pedagogical tools for learning. © 2011 Springer-Verlag.

Although much literature exists on how technology can promote tourism industry, little is known about this phenomenon in developing countries. The existing technologies have not been able to successfully tackle the infrastructural and connectivity problems. To tackle the challenges, the use of low cost and simple technologies is imperative. This paper therefore discusses the role of wireless broadband technologies in promoting tourism industry in Tanzania. It explains how WiMAX, a modern wireless technology, can add a competitive advantage to a tourism industry by giving tourist the ability to stay in-touch with the world whilst enjoying safaris in the most remote areas in the world. This paper is most useful to academician, researchers and stakeholders of tourism industry who looks into ways of promoting e-tourism and e-commerce in developing areas. © 2010 IEEE. Source
