    The need to introduce technologies in rural areas so as to capacitate communities towards overcoming various socio-economic challenges remains a priority in emerging economies. We rely on the foregoing for the investigation in the Kgautswane community in South Africa, of a range of socio-economic challenges that can be addressed through ICT. Identified challenges are further filtered for the selection of an appropriate intervention based on previous experience in the community. The appropriate challenge forms the basis for the development and deployment of an eProcurement ICT solution for small scale traders in the community with emphasis on the concept of a sociopreneur (socio-economic service provider) for leveraging the socio-economic impact of the solution deployed. The overall process is relied upon to develop a roadmap for ICT solution deployment in rural areas that can serve as a blueprint for undertaking similar interventions in the framework of ICT for development

    Customer profiling has recently gained much recognition in the e-commerce domain because of the benefits it is capable of bringing to online business. Customer profiling has been implemented in various systems development approaches such as in a client-server environment. Recently there has been an increase in the number of organisations adopting and implementing e-commerce systems using service-oriented architecture (SOA) principles. This research set out to determine how a customer profile can be implemented using open source SOA implementation tools, and how SOA-based customer profiles can be utilised to provide appropriate personalisation in an SOA environment. The research further endeavoured to complete a comparative study on customer profile implementation in two different architectures, namely SOA and client-server. An extensive literature review was conducted on SOA, customer profiling and e-commerce systems development. SOA enabling technologies, such as, web services, enterprise service bus (ESB) and open source Sun Java SOA implementation tools, for example, Open ESB, GlassFish application server and Netbeans IDE were analysed. A Java web services-based customer profiling system was prototyped following SOA design principles. An end-user evaluation survey was conducted using eye tracking with a sample of 30 participants. The evaluation was done on two e-commerce systems with the same interface but running on two different customer profile back-ends, SOA and client-server. The results show that participants did not experience significant difference between the two systems, however, eye tracking results showed a significant difference between the two systems. The research concluded that customer profiling using SOA offers more benefits than implementations using other architectures such as client-server. SOA component-based development proved to be easier to manage, develop, integrate and improves interoperability between different technologies. The research brought together necessary techniques and technologies that organisations can use to implement SOA. Using SOA, organisations can integrate and utilise different technologies seamlessly to achieve business goals

    A context-aware model to improve usability of information presented on mobile devices

    Online information access on mobile devices is increasing as a result of the growth in the use of Internet-enabled handheld (or pocket-size) devices. The combined influence of recent enabling technologies such as Web 2.0, mobile app stores and improved wireless networks have driven the increase in online applications that allow users to access various types of information on mobile devices regardless of time and location. Examples of such applications (usually shortened to app) include: social media, such as FacebookTM App and TwitterTM App, banking applications such as (Standard Bank South Africa)TM Mobile Banking App and First National Bank (FNB) BankingTM App, and news application such as news 24TM App and BBCTM News App. Online businesses involved in buying, selling and business transaction processing activities via the Internet have exploited the opportunity to extend electronic commerce (e-commerce) initiatives into mobile commerce (m-commerce). Online businesses that interact with end user customers implement business to consumer (B2C) m-commerce applications that enable customers to access and browse product catalogue information on mobile devices, anytime, anywhere. Customers accessing electronic product catalogue information on a mobile device face a number of challenges such as a long list of products presented on a small screen and a longer information download time. These challenges mainly originate from the limiting and dynamic nature of the mobile apps operating environment, for example, dynamic location, bandwidth fluctuations and, diverse and limited device features, collectively referred to as context. The goal of this research was to design and implement a context-aware model that can be incorporated into an m-commerce application in order to improve the presentation of product catalogue information on m-commerce storefronts. The motivation for selecting product catalogue is prompted by literature which indicates that improved presentation of information in m-commerce (and e-commerce) applications has a positive impact on usability of the websites. Usable m-commerce (and e-commerce) websites improve efficiency in consumer behaviour that impacts sales, profits and business growth. The context-aware model aimed at collecting context information within the user environment and utilising it to determine optimal retrieval and presentation of product catalogue in m-commerce. An integrated logical context sensor and Mathematical algorithms were implemented in the context-aware model. The integrated logical context sensor was responsible for the collection of different types of predetermined context information such as device specification or capabilities, connection bandwidth, location and time of the day as well as the user profile. The algorithms transformed the collected context information into usable formats and enabled optimal retrieval and presentation of product catalogue data on a specific mobile device. Open-source implementation tools were utilised to implement components of the model including: HTML5, PhP, JavaScript and MySQL database. The context-aware model was incorporated into an existing m-commerce application. Two user evaluation studies were conducted during the course of the research. The first evaluation was to evaluate the accuracy of information collected by the context sensor component of the model. This survey was conducted with a sample of 30 users from different countries across the world. In-between the context sensor and main evaluation surveys, a pilot study was conducted with a sample of 19 users with great experience in mobile application development and use from SAP Next Business and Technology, Africa. Finally an overall user evaluation study was conducted with a sample of 30 users from a remote area called Kgautswane in Limpopo Province, South Africa. The results obtained indicate that the context-aware model was able to determine accurate context information in real-time and effectively determine how much product information should be retrieved and how the information should be presented on a mobile device interface. Two main contributions emerged from the research, first the research contributed to the field of mobile Human Computer Interaction. During the research, techniques of evaluating and improving usability of mobile applications were demonstrated. Secondly, the research made a significant contribution to the upcoming field of context-aware computing. The research brought clarity with regard to context-aware computing which is lacking in existing, current research despite the field’s proven impact of improving usability of applications. Researchers can utilise contributions made in this research to develop further techniques and usable context-aware solutions

    The advent of computer-based knowledge management systems has changed the world, especially in the way businesses operate, making them an integral aspect to modern economies and the drivers of success. Studies show that the implementation of computer-based knowledge management systems is challenging, particularly in healthcare institutions. This paper presents a study that was undertaken to identify the causes of challenges encountered when implementing computer-based knowledge management systems in healthcare institutions. A case was used as this study’s research methodology in which three private hospitals based in Johannesburg, South Africa, were utilized. Six participants, two from each private hospital, were purposively selected and interviewed. Researchers collected data in the form of notes and qualitatively analyzed it. The following findings were identified: failure to make organizational culture change to align with computer-based knowledge management systems; no support, commitment and accountability; knowledge gap between medical and knowledge management designers; fast-changing of technology; shortage of skilled human resources; failure to convert tacit and explicit information into systematic knowledge; and failure to comprehend healthcare complexity. The aim of this study is to present a comprehensive synopsis of the causes of challenges encountered when implementing computer-based knowledge management systems in Johannesburg healthcare organizations

    A Context-Aware Model to Improve Usability of Information Display on Smartphone Apps for Emerging Users

    Get PDF
    Smartphones have become a reliable technology for accessing information and services in rural communities. Mobile applications, such as social media and news apps running on smartphones, are no longer exclusively utilised by users in developed communities. Mobile applications are accessed in highly contextualised environments. This paper discusses a context-aware model that was implemented to improve the usability of information presented on smartphone applications for emerging users. User evaluation was conducted within a remote area in South Africa with a sample of users, most of whom did not have prior experience in using computer applications. The results of the evaluation present empirical evidence that the model can improve the usefulness of mobile applications and their adoption in rural areas by emerging users who primarily rely on smartphones for accessing a variety of information sources and services. The findings can be utilised as a blueprint for implementing sustainable mobile interventions for emerging users
