Strategic information systems planning (SISP) is a key issue to IS managers. The SISP approach employed by organizations is very much dependent on the internal and external environment. Recent research points to a gap between the manner in which IS ...

Systematic software reuse is still the most promising strategy for increasing productivity and improving quality in the software industry. Although it is simple in concept, successful software reuse implementation is difficult in practice. A reason put ...

Ant-like agents forage between two points. These agents' probabilistic movements are based on the use of two pheromones; one marking trails towards the goal and another marking trails back to the starting point. Path selection decisions are influenced ...

Vulnerable children in Africa fail to access basic social services and people they need to advance in life because they are not empowered enough to do so and have little information to their benefit. This paper describes the development of SINGA which ...

Designing graphical user interfaces (GUIs) is an arduous task that requires both functional and aesthetic considerations, often relying on documented style guides and design principles. Style guides and principles are mostly prescriptive in terms of ...

The high rate of systems development (SD) failure is often attributed to the complexity of traditional SD methodologies (e.g. Waterfall) and their inability to cope with changes brought about by today's dynamic and evolving business environment. Agile ...

It is within highly integrated technology environments that information security is becoming a focal point for designing, developing and deploying software applications. Ensuring a high level of trust in the security and quality of these applications is ...

The majority of guidelines and principles for design of technology are aimed at products for adults. The limited guidelines available for design of young children's technology do not focus sufficiently on age-related requirements or they offer high-...

One of the most prominent problems that persons with disabilities face in South Africa, is access to relevant disability related information. To address this need the South African National Accessibility Portal (NAP Portal) was developed, that enable ...

A study of 821 South African Internet users was undertaken to assess attitudes towards the personalization of online content, concerns about privacy, and willingness to provide explicit personal information and to allow implicit gathering of web usage ...

High-performance computing systems are important in scientific computing. Clusters of computer systems --- which range greatly in size --- are a common architecture for high-performance computing. Small, dedicated clusters are affordable and cost-...

Powerful mobile computing devices such as smartphones and PDAs are becoming more numerous and affordable. These mobile devices are ideal for tourists needing to search for suitable points-of-interest (POIs) such as restaurants or accommodation. This ...

In this paper we investigate the feasibility of using two different model-checking techniques for solving a number of classical AI planning problems. The ProB model checker, based on mathematical set theory and first-order logic, is specifically ...

Dwesa is a rural town situated in South Africa's Eastern Cape Province. Its residents are plagued with the challenges of poverty, poor access to public services, unemployment and low levels of literacy. A project is currently underway in Dwesa to ...

The pervasiveness of mobile devices has created a substantial market for mobile applications and games that continues to grow extremely rapidly. Consequently, the mobile game industry has firmly asserted itself as a significant industry with major ...

"Grounded Theory" has been employed quite widely in studies of information systems (IS) phenomena. A survey of IS literature reveals conflict in the understanding and use of "grounded theory". The term "grounded theory" is often used as a catch phrase ...

Open source software (OSS) is increasingly becoming an alternative for proprietary software (PS), particularly in the government sector globally. The adoption and implementation of OSS by the government sector is cited as one of the enablers for the ...

Over a decade ago, simply recording a few minutes of CCTV footage required special hardware. Today, with the emergence of new sensors and improved processing hardware, a relatively inexpensive personal computer can process and store video in real-time, ...

Recent studies have indicated an increase in customer profiling techniques used by e-commerce businesses. E-commerce businesses are creating, maintaining and utilising customer profiles to assist in personalisation. Personalisation can help improve ...

Grid computing is often out of reach for the very scientists who need these resources because of the complexity of popular middleware suites. Some effort has gone into abstracting away these complexities using graphical user interfaces, some of which ...

Earlier research into the examination timetabling problem focused on applying different methodologies to generate solutions to the problem. More recently research has been directed at developing hyper-heuristic systems for timetable construction. Hyper-...

There has been a large amount of research into the automatic generation of school timetables. Methodologies such as constraint programming, simulated annealing, Tabu search and genetic algorithms have been applied to the school timetabling problem. ...

The usability of touch-tone Interactive Voice Response (IVR) systems is dismal. Clients would rather speak to a contact centre agent than navigate through the menu structure found in these systems. Contact centres, due to a variety of reasons, most ...

Technology adoption has been studied from a variety of perspectives. Information systems, Sociology and Human-Computer Interaction researchers have come up with various models incorporating factors and phases to predict adoption that, in turn, will lead ...

Increasingly mobile device applications are requiring users to perform text-intensive tasks, such as text messaging, thus creating a demand for more efficient and easier text entry methods. The current diversity of mobile phones come with an equally ...

Large student numbers often drive teaching staff to consider greater degrees of automation of assessment activities. In introductory Computer Science classes - where submitted programs need to repeatedly be compiled, executed and tested -automation is ...

Parallel to the Open Source Software movement, there is an increased demand and need for free, open access to information resources. The Open Access initiative is characterized by two strategies: namely the promotion of self-archiving or, alternatively, ...

e-Government is a global technology transfer taking designs from one context into a different context. This paper finds that the context of design inscribed into e-Government systems in both explicit and implicit ways can produce a mismatch with the ...

Visualising map-based data on mobile devices presents many challenges. Small displays, comparatively slow hardware and awkward interaction techniques all combine to make mobile map-based visualisations difficult to design and often frustrating to use. ...
