Item ICT Definition Implication on ICT Career Choice and Exclusion among Women(2016-05) Muchiri, Michael Njoki; Wabwoba, Franklin; Micheni, Elyjoy MuthoniOne of the most noteworthy challenges in society in the 21st century is sustainable development. The usefulness of ICT has led to an overwhelming demand for electronics such as computers and mobile phones. ICT is vital for poverty reduction and in the growth of sectors such as agriculture, business, health, education etc. Applying ICT to drive any development has its advantages and disadvantages. Therefore, its measurement should be focused on whether the benefits outweigh the pitfalls. The purpose of carrying out this research is because most development initiatives in Africa are being undertaken with the use of ICT. Therefore, this paper surveys the literature on ICT for sustainable development without the digital divide and how ICT can lead to un-sustainability in Africa. Findings indicate that driving sustainable development through ICT initiatives bring much greater benefits than negative consequence.Item ICT for Sustainable Development without Digital Divide in Africa(2020-04-25)One of the most noteworthy challenges in society in the 21st century is sustainable development.

The architecture of most of the ERP is based on the Service Oriented Architecture (SOA) where each module can be called as service. In most of the contract signed between the vendor and the university, payment is tied to the level of implementation. The Question is how to then measure the level of implementation? This paper proposes a metric that could be used in evaluation of the degree of implementation. The metric was derived based on an acceptance test on each of functionality of module as per terms of reference. The result of a test was rated as a Fail, Pass, or Query The result was then coded such that a fail was assigned a zero (0), pass one (1) and query a half (½). From which a metric was derived which measures the level implementation.Item Simplifying the Opaqueness and Dilemma of the Computing Disciplines for the Common Person in Society(2023-12) Mohammed Swaleh Mohammed; Wabwoba, FranklinThe computing fields have grown increasingly influential in modern times, yet their complexities and technical terms can prove problematic for the public to comprehend. This paper proposes to bridge this gap, introducing readers to the five major computing disciplines as per the Association of Computing Machinery (ACM), 2016: computer science, Information System, software engineering, computer engineering, and information technology. An additional more recent discipline which does not fall under the 5 ACM disciplines, Information Communication Technology was also introduced. The paper first examines the evolution of the Computing disciplines from the 1960s. Then the paper briefly discusses each discipline and how the disciplines overlap with each other through using secondary data materials. A section on the new and emerging computing technologies outlines the recognition status by the society. The interdisciplinary nature of the computing disciplines necessitated the need to simplify it. Thus, a table was done which summarized various works of various researchers who had researched on the computing disciplines.Item The Role of ICT in Social Inclusion: A Review of Literature(2023-01) Muchiri, Njoki; Wabwoba, FranklinThe questions we seek to answer in this paper are; Have ICT contributed to enhance social inclusion? Has use of ICT brought new forms of exclusion? And what is the way forward in using ICT for an inclusive society? Desk Top research was used. From the findings, one form of exclusion often leads to another, resulting to a cycle. a spanner and Nut Model was developed to show how Knowing which exclusion to reduce in order to break the cycle is critical in determining the type of ICT and how to apply it in order create an inclusive society.Item Pervasiveness of green ICT awareness amongst Kenyan ICT personnel(2013-01) Wabwoba, Franklin; Wanyembi, Gregory W.; Omuterema, Stanley; Mutua, Stephen MakauThere has been growing concerns about the rising costs of doing business and environmental degradation world over. Green ICT has been proposed to provide solutions to the two issues yet it is not being implemented fully in developing nations like Kenya despite the availability of the technologies of doing it. The study investigated pervasiveness of green ICT awareness amongst the ICT personnel, how they perceive it to be relevant to their organisations and the drivers towards implementation of the same. The study surveyed ICT personnel in four cases using a questionnaire on a seven scale likert scale. The study established that awareness level of green ICT in Kenya is low when compared with developed nations. It also established the green ICT drivers and how ICT personnel perceived it to be relevant to their organisations. The study recommends the raising of green ICT awareness levels through aligning the ICT personnel’s capacities.Item Usability Evaluation of Kenyan Universities Websites for Webometrics Ranking(2022-02) Mukanda, Adeline; Buguah, Samuel M.; Wabwoba, FranklinThe study aimed to evaluate the usability of Kenyan universities websites for webometrics ranking using web analysis tools. The target population for the study was the top five (5) universities in the January 2020 edition of webometrics ranking in Kenya. The study collected, analyzed, and evaluated website usability of the following website attributes: URL structure, Website Age, Uptime, Content Management System, website hosting service provider, Responsiveness, Browser compatibility, Color contrast, Domain Authority, Domain Backlinks, Website traffic, Broken Links, Number of Subdomains, Website Speed, Indexed webpages, Website compression, Search Engine Optimization, Website content utility, Website design and Website Accessibility. After analysis, it was noted that Kenyan universities need to improve on some of the usability criteria used in the study where a score of less than 50% was attained, such as Website compression, website speeds, website subdomain, website indexed pages, website traffic, website backlinks, website colour contrast and website design.Item The Role of Virtualization towards Green Computing and Environmental Sustainability(2017-06) Motochi, Vincent; Samuel Barasa; Owoche, Patrick; Wabwoba, FranklinThe environment has become a key concern by the entire world and global warming is increasingly attracting attention in many conferences. Moreover, energy usage in data centers has become a concern bearing in mind the fact that the more energy is used in data centers, the more it affects the environment with emissions, which eventually cause global warming. This paper studies the role of virtualization towards green computing and environmental sustainability. Server virtualization is emerging as the prominent approach to consolidate applications from multiple applications to one server, with an objective to save energy usage. This research identified the virtualization environments, identified green computing environments, and then established how virtualization could be used to attain environmental sustainability. This paper was developed on an experiment design. The researcher reviewed an empirical experiment to investigate how server virtualization affects the energy usage in physical servers. Through this analysis, the researcher identified a fundamental trade-off between the energy saving from server consolidation and the detrimental effects (e.g., energy overhead and throughput reduction) from server virtualization. This paper found out that a server consumes a substantial amount of energy when idle thus the importance of consolidation. Secondly the energy overhead depends on the type of hypervisor used and the application architecture. Thirdly for a given traffic load, the energy cost can be minimized by launching an optimal number of virtual machines. The analysis and review results show that virtualization brings substantial energy savings, promotes green computing and would be a clear methodology to conserve the environment in the technology world today. Therefore, green computing is a well balanced and sustainable approach towards the achievement of a greener, healthier and safer environment without compromising technological needs of the current and future generations.Item Green ICT Readiness Model for Developing Economies: Case of Kenya(2013) Wabwoba, Franklin; Omuterema, Stanley; Wanyembi, Gregory W.; Omieno, Kelvin KebatiThere has been growing concerns about the rising costs of doing business and environmental degradation world over. Green ICT has been proposed to provide solutions to the two issues yet it is not being implemented fully in developing economies like Kenya. For its implementation, it is critical to establish the level of green ICT readiness of organisations to inform where to start and where to put more emphasis. Over the past few years this has been done using Molla’s G-readiness model. However, this model assumes the basic level of Greadiness to be same for both developed and developing economies to be the same with regard to ICT personnel preparedness. Based on green ICT readiness in Kenya, the relationship between ICT personnel’s gender, age and training with the G-readiness variables as proposed in Molla’s G-readiness model was investigated. The study surveyed ICT personnel in four cases using a questionnaire on a seven scale likert scale. It established that there exists a significant relationship between the ICT personnel related variables and the G-readiness variables. Based on the findings on the relationship, the study extended Molla’s G-readiness model to include a sixth dimension of personnel readiness.Item Evaluating the Role of Information and Communication Technology (ICT) Support towards Processes of Management in Institutions of Higher Learning(2012-07) Ujunju, Michael Okumu; Wanyembi, G.; Wabwoba, FranklinThe role of Information and Communication Technology in achieving organization’s strategic development goals has been an area of constant debate, and as well perceived in different management dimensions. Most universities are therefore employing it (ICT) as a tool for competitive advantage to support the accomplishment of their objectives. Universities are also known to have branches or campuses that need strong and steady strategic plans to facilitate their steady expansion and growth. Besides, production of quality services from the various levels of management in these universities requires quality strategic plans and decisions. In addition, to realize the steady growth and competitive advantage, ICT not only has to be an additive but a critical component towards supporting management processes in the universities. This research sought to determine the role of ICT in supporting management processes in institutions of higher learning in Kenya. The research investigated how the different levels of management used ICT in their management processes and whether the use had any effect on management processes. The research further made recommendations to the universities on better use of ICTs in their management processes. A public university in Kenya was used as a case study in this research.
