As a result, developed and developing countries are continuously making efforts to implement e-Gov projects as they are proven to enhance good governance and improve the delivery of government services to the citizenry. Whereas developed countries such as the Republic of Korea, the United States of America, Singapore, and Denmark have successfully transformed their economies through e-Gov, the story is different for developing countries that have had many failed and unsuccessful e-Gov projects. This paper explores the peculiar critical success factors of e-Governance project initiation in the context of both developed and developing countries, with special emphasis on developing countries, and then proposes a preliminary framework for e-Gov project initiation based on investigated critical success factors. This preliminary framework forms the basis for the development of a framework for benchmarking the overall lifecycle of e-Gov projects in developing countries.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127372724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested the ICT culture variables as well as school location factor in respect to school's digital divide. A survey sample contained 17 regional city schools from three different locations - central city in the region, towns away from the central city, and village schools. The survey instrument was developed with ten ICT culture variables. The variables in the instrument met the Cronbach's Alpha threshold value of α = 0.70. Data was analysed with Descriptive statistics, Hierarchical Cluster analysis, Independent t-test, and Canonical discriminant analysis. We found that school location did not determine the schools DD, nonetheless the schools were digitally divided, -2 clusters were found among schools. This DD was determined by certain ICT culture variables: Teacher's ICT competences and the usage of ICT in Teacher's professional practice were paramount.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121324944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ferreira","doi":"10.1109/ISTAFRICA.2015.7190522","DOIUrl":"https://doi.org/10.1109/ISTAFRICA.2015.7190522","url":null,"abstract":"The combination of using Wi-Fi and ZigBee technologies in an application to monitor cattle has the potential to increase the range of the network when the animal herd is roaming out of range of the sink. This paper investigates combining a Wi-Fi and ZigBee transceiver on the same sensor node to reliably obtain data of mobile cattle in a field. The solution proposed is a hybrid network conjoining the IEEE 802.11b/g and IEEE 802.15.4 protocols. Cattle as herd animals always roam in a herd manner. It has been observed that when the herd moves far away from the sink, the link between the herd and the sink breaks because there is no relay node in the middle. In order to maintain the link between the herd and the sink a heterogeneous network is proposed. The proposed solution extends the range of a ZigBee network used for cattle monitoring by pairing with the IEEE 802.11b/g protocol. In this paper, we implement two protocols IEEE 802.11b/g and 802.15.4/ZigBee in a hybrid network. The nodes have been designed to avoid interference between the two protocols and ensure good coverage of 802.11b/g in the area where the cattle moves. Moreover the design had to be cost effective so it could be useful for small to medium or large commercial farmers who are most susceptible to cattle theft.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128352112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper first includes a Verification & Validation (V&V) method developed for evaluating of Future Internet software components implementation in a multi-sectorial environment. The proposed approach is based on best of breed V&V methodologies characterized by a structured assessment of the software quality at different levels and a reduced set of business indicators able to evaluate the business impact of the integrated solution. All of these are deployed via a configurable V&V Package based on a web interface. Second it includes a methodology for maximising post project impact creating through activity monitoring. The method used is based on impact waves and success tree approaches. Examples are given of practical implementation in the EU FP7, FI-PPP Project FITMAN.

These SMS-based services reach areas where bank branches or auto telling machines would not be feasible thereby enabling financial inclusion among the unbanked and low-income earners. However, the vulnerability of its service delivery platform makes it attractive to fraudsters. Lack of digital forensic readiness (DFR) scheme, specifically designed for BB, to capture and preserve potential evidence for further investigation of fraud remains a challenge in this domain. The availability of digital evidence maximises the potential of an organisation to successfully conduct investigation at a reduced cost. Therefore, branchless banking service providers should consider incorporating digital forensic readiness in their security strategies. In this paper, the authors propose a digital forensic readiness scheme that addresses the problem of fraud in branchless banking.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129876836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the majority of institutions have been adopting these systems without conducting usability evaluations. As a result, users tend to find these systems not easy to use, learn and do not meet their learning objectives. At the moment, there is relatively small and inadequate heuristics that can be used to evaluate LMS taking into account both system features and didactic effectiveness. This study presents a comprehensive heuristics usability that consolidates interface usability, didactic effectiveness and motivation to learn. The heuristics were validated through expert evaluation of the University of Dar es Salaam and Shuledirect systems. The proposed heuristics managed to uncover several usability problems. The findings from this study have shown that the proposed heuristics are appropriate and effective to be used for evaluating LMS deployed in Africa.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124608736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The provision of healthcare services in schools thus responds to the need of children but also increases the efficacy of other investments in child development, ensures better educational outcomes, achieves greater social equity and is a highly cost effective strategy. One such a strategy is South Africa's Integrated School Health Policy, which is a mechanism to improve the general health of school-going children as well as removing health barriers to learning, in order to improve education outcomes. The context in which the policy is implemented, however poses many challenges resulting in school health services not functioning in far-off schools in rural parts of the country of which the shortage of qualified nursing staff, lack of appropriate equipment and the remoteness of schools are contributing factors. In an attempt to find a solution to this problem, research into the use of technology as an alternative way to provide access to school healthcare services, are currently investigated. This paper shares how school nurses in rural Eastern Cape, use mobile devices with specific mobile applications, to improve access to healthcare and health education in schools.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124690674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research was undertaken as a single case study within the Open and Distance Learning (ODL) context in South Africa. Qualitative data was captured through policy document analysis using the Framework for Qualitative Data Analysis. The findings of the study revealed that UNISA has many policies that guide lecturers when providing mobile centric services to students. The policies cross-reference but some gaps were observed on how the institution provides lecturers with mobile technology infrastructure, technical support, emotional support and pedagogic support. Hence, this study proposes some recommendations on how the policy could support lecturers in providing mobile centric services in teaching and learning.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115786299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Majawa","doi":"10.1109/ISTAFRICA.2015.7190528","DOIUrl":"https://doi.org/10.1109/ISTAFRICA.2015.7190528","url":null,"abstract":"This study examined the use of Information and Communication Technologies (ICT) by students at the College of Medicine as a tool for supporting learning. Questionnaires containing both open and closed questions were administered to 65 undergraduate students representing 10% of the total population of students. The students were randomly selected within their departments as strata for the study. Data analysis was undertaken using Microsoft Excel for quantitative data and thematic analysis for qualitative data. The major findings of the study revealed that most students at the College of Medicine realise and appreciate the vital role which ICTs contribute to their academic work when integrated successfully. However, the integration of these technologies is negatively affected by a number of factors including inadequacy of ICT facilities, power/electricity interruption, slow Internet flow, viruses, and limited time for students to access ICT facilities. The findings also showed that among the ICTs that the College of Medicine provides, computer terminals for use and Internet services are highly used by students. The least are e-journals and e-learning. In order for the College to enhance students' competencies with ICTs, the researchers recommended that the College should consider purchasing more ICT resources, extending opening hours for the Internet/ICT labs, acquiring large bandwidth and widening the network coverage throughout the campus including the hostels. The study did not involve the other categories of people that use ICT based resources on the campus such as postgraduate students and members of staff who could have enriched the findings of the study. The study has brought to light the students' concerns regarding the use ICTs at the College, it is hoped that if management of the College decides to implement the recommendations made by the researchers, the integration of ICTs in the students learning activities will be enhanced, thereby maximising usage of ICT based services at the College. The study has revealed unique issues regarding undergraduate students' usage of ICTs at the College of Medicine. For instance, lack of ICT skills is a major problem in other institutions of higher learning in Malawi which is contrary to the findings of this study.","PeriodicalId":208344,"journal":{"name":"2015 IST-Africa Conference","volume":"117 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128391419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
