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.

Keywords	Privacy, privacy policies, consumer trust, universities, higher education, cookies, personal data

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.

Abstract

This paper compares file systems in Ubuntu Linux and FreeBSD and then analyzes the best utilization. The generic file systems, Extended File System (EXT2) of Linux and Fast File System (FFS) of FreeBSD operating systems, are evaluated using benchmark tests. It is proposed that a better file system could be assembled and implemented for improving performance and reducing bottleneck with consideration of modern intricacies.
