    Hadoop and big data readiness in Africa: a case of Tanzania
    (International Journal for Scientific Research & Development (IJSRD), 2013) Malero, Augustine; Seif, Hassan
    Big data has been referred to as a forefront pillar of any modern analytics application. Together with Hadoop which is open source software, they have emerged to be a solution to the processing of massive generated both structured and unstructured data. With different strategies and initiatives taken by governments and private institutions in the world towards deployment and support of big data analytics and hadoop, Africa cannot be left isolated. In this paper, we assessed the readiness of Africa with a case study of Tanzania in harnessing the power of big data analytics and hadoop as a tool for drawing insights that might help them make crucial decisions. We used a survey in collecting the data using questionnaires. Results reveal that majority of the companies are either not aware of the technologies or still in their infancy stages in using big data analytics and hadoop. We identified that most companies are in either awakening or advancing stages of the big data continuum. This is attributed by challenges such as lack of IT skills to manage big data projects, cost of technology infrastructure, making decision on which data are relevant, lack of skills to analyze the data, lack of business support and deciding on what technology is best compared to others. It has also been found out that most of the companies' IT officers are not aware with the concepts and techniques of big data analytics and hadoop.

    Harnessing the power of mobile phone technology to improve maternal healthcare in Tanzania: Proposed model
    (Foundation of Computer Science (FCS), 2014) Nyamawe, Ally S.; Seif, Hassan
    In the effort to reduce maternal mortality rate, Millennium Development Goal (MDG) 5 was declared globally. Tanzania has no exception on this. Maternal mortality and morbidity is still an enduring challenge in Tanzania. In 2010 the Maternal Mortality Rate (MMR) was recorded at 454/100,000 live births. Despite of the devoted efforts and significant progress that Tanzania has made in reducing MMR, still the situation demands for more improved intervention. One among the contributors of maternal mortality is lack of education to expectant mothers. In this paper, a model with a pivotal role to extend health information accessibility to expectant mothers is proposed. A proposed model is exploiting the potential and power of mobile phones to deliver its services. Existing extended network coverage and expansion of mobile phone usage are the unprecedented advantages that would also be exploited.

    Mobile learning a new wave of learning: a survey among university of Dodoma students
    (Foundation of Computer Science, 2014) Shao, Deo; Seif, Hassan
    Mobile technologies are increasingly becoming an integral part of student’s lives in academia. Devices such as smartphones, tablets, and e-book readers connect users to the world instantly, heightening access to information and enabling interactivity with others. Applications that run on these devices let users not only consume but also discover and produce content. As such, they continue to transform how college students learn, as well as influence their learning preferences, both within and outside the classroom. This study survey the adoption of mobile phones among university students and their attitudes on the uses of cell phones as a venue for learning their class handouts and hunt ground for educational materials. The findings show that 53.3% of students own smart-phones while 41.8% own basic cell-phone (Featured phone). 42.4% of them use their cell phones to search educational reference materials online, 7.3% of them use cell phones to play games, 24.3% use their cell phones to read online news, 33.3% use their cell phones to connect to social networks. Overall these results suggest mobile phone as promising device for delivering learning materials to students.

    The role of ICT in reducing maternal and neonatal mortality rate in Tanzania
    (Foundation of Computer Science (FCS), 2014) Nyamawe, Ally S.; Seif, Hassan
    Tanzania is striving to achieve Millennium Development Goals (MDG) 4 and 5 that call for reducing Neonatal and Maternal Mortality Rate (MNMR) by 2015. In 2010, Neonatal Mortality Rate (NMR) was recorded at 51 per 1,000 live births and Maternal Mortality Rate (MMR) at 454 per 100,000 live births. Despite of the devoted efforts and significant progress, still the mortality rate needs attention and effective intervention to cut it down considerably. The capability and power of Information and Communication Technology (ICT) need to be effectively exploited in revolutionizing health sector in Tanzania. The witnessed expansion of mobile phones usage and extended network coverage presents potential opportunity in enhancing quality of Maternal, Neonatal and Child Health (MNCH) services delivery. This paper explores the role of ICT in reducing MMR and NMR, existing solutions are intensely reviewed to discover what is lacking and provide necessary recommendations.
