Abstract

It is expected that improved connectivity will enable African Tertiary education and research institutions to generate a proportionate amount of intellectual property goods to achieve parity with the rest of the world. Nevertheless this vision can only be attained through intensive collaborative activities. The emergence of large-scale e-infrastructure projects in Africa reflects a trend toward more complex configurations of scientific collaboration. ....

Abstract

Software metrics gives developers and their client and users of Software information about the quality of their Software products. They are employed in taking decisions at various levels of Software Life Cycle (SLC). This paper presents a novel metric for measuring the readability of Software Source Code (SC). Maintenance changes (addition, removal or modification), though, are initially carried out on the Software design artifacts, they are eventually performed on the Software SC as the finished product. Thus this metric is relevant in estimating the readability quality of SCs. The metric is ratio scaled and size independent. Results showed that the metric objectively measures the readability of SC.to alleviate such impacts.

Abstract

Due to demand in online services, universities throughout the world are increasing the content of their Web sites and adding features, such as online applications and e-learning. However, adding online services requires that personal data is kept within computerized systems, thus putting personal private information at risk. Online consumers express concern about the risk of their personal private data and demand to know how organizations will protect their records. It is imperative that firms have mechanisms to guard their data and publish protection information within online privacy policies to mitigate user distrust. However, although industry privacy groups may recommend better protection and some countries may legislate its use; this is not universal in all university sites. This study analyzes 90 universities site throughout the world to determine the use of privacy protection. The results show a lack of use of certain privacy mechanisms. The research suggests methods for improving protection.

Abstract

During the last 20 years ITIL (IT Infrastructure Library) has been evolving with the latest version published in 2007. Incident Management and Problem Management are two main activities of ITIL service operation framework which handles incidents and their root causes respectively. Service Desk systems are software tools that help IT organizations in handling incidents and problems. On the other hand since Knowledge Management emerged, many corporates adopted Knowledge Management. By adding a Knowledge Management structure to the ITIL framework in 2007 the path of utilization Knowledge Management in Service Desk system is smoothed, however, the number of Service Desk systems that have adopted a Knowledge Management structure is few and the adoption is not practical in many cases. In this paper we try to address this issue and focus on Knowledge Management structure utilization in Service Desk systems by integrating Case-based Reasoning and Service Desk structure.

Abstract

Quality and an emphasis on quality are must have ingredients for an organization to be successful. Therefore, in the present environment of fast pace software development, quality plays an essential role when it comes to the long term viability of IT organizations. As a result of continuous quality improvement, IT organizations have defined and implemented various quality processes and software development methodologies in order to achieve a higher quality standard. Currently, one of the most popular software development methodology is known as the Agile Software Development Methodology. Some IT organizations have been successful with the implementation of this new framework, while other IT organizations have experienced less success or complete failure. The purpose of this study is to provide some answers to the following thesis question that has not been answered yet by currently available literature related to Agile Software Development: in what ways does the implementation of Agile Software Development Methodology impacts quality within IT organizations? According to Dybå & Dingsøyr (2008, p.14), Agile Software Development, the innovative “movement”, has a considerable impact on organizations specialized in IT software development, and poses several hurdles that ultimately impact quality within IT organizations. This study takes a look at the impact of Agile Software Development on quality within the organizational, methodical, and cultural framework and provides industry standard recommendations to alleviate such impacts.

A Dark Side of Computing and Information Sciences: Characteristics of Online Groomers

Abstract

The European Online Grooming Project from 2009 to 2011 involved researchers from Norway, Italy, Belgium and the UK. The project had three separate but interlinked phases. The first was a scooping project. The second and third phases involved interviews with convicted online groomers across Europe and dissemination activity respectively. The key features of grooming behavior the study identified do not apply to all groomers in all contacts they have with young people. These features of online grooming include factors that help maintain the behavior such as the online environment, dissonance and offenders perceptions of young people and their behavior. The research also identified salient behaviors in the grooming process such as: scanning the online environment for potential people to contact, the identity adopted by the groomer (be it their own or another); the nature of contact with the young person; the different ways in which the online groomer can intensify the process of grooming and the diverse range of outcomes toward the end of the process. In particular, it is clear from the research that not all episodes of online grooming result in a physical meeting. The first ‘type’ of groomer identified is the distorted attachment offender. Men in this group had offence supportive beliefs that involved seeing contact with the young person as a ‘relationship’. The second type is the adaptable online groomer. This group of men had offence supportive beliefs that involved their own needs and seeing the victim as mature and capable. Finally, the hyper-sexualized group of men was characterized by extensive indecent image collections of children and significant online contact with other sexual offenders or offender groups.

Abstract

Industrial and commercial wastes must be classified at least two times on the way from the owner of the waste to the waste disposal facility in order to ensure that waste handling is in conformity with the law. Wastes classification as dangerous goods is very difficult because they consist of many components with diverse dangerous properties. This paper presents a Web-based expert system we developed for the classification of wastes to overcome this difficulty. It joins the expert system intelligent knowledge and the capability of the Web to put the knowledge of experts anywhere the expert can’t go. The system uses a set of if-then rules to classify waste.
