The Role of Virtualization towards Green Computing and Environmental Sustainability
(2017-06) Motochi, Vincent; Samuel Barasa; Owoche, Patrick; Wabwoba, Franklin
The 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.
Alternative Risk Scoring Data for Small-Scale Farmers
(2023-01) Otieno, Benjamin; Wabwoba, Franklin; Musumba, George
Small-scale farmers suffer unfairness during credit risk scoring. This arises from the fact that scoring done using
computer machine-learning algorithms has an inherent bias, otherwise called algorithm bias. The data that the small-scale
farmers present is another source of bias. This paper explores these data types to bring out the specific challenges with the data
and how the same can be remedied. The research findings show that of the possible 23 data types lenders ask from farmers, 14
are regarded as important. Out of these 14, 7 are commonly unavailable while the remaining 7 are not, introducing missing
data records. The findings also show that other than the personal/behavioral data that the loan-seeker provides, where the
lender asks for historical or environmental data, there is room for the loan-seeker to provide misleading information. This paper
proposes 14 data types that can improve the quality of credit risk scoring. The study further proposes using the Internet of things
and blockchain to source the environmental and historical data to improve the availability of the missing and outlier challenge
in data.
Information Technology Research in Developing Nations: Major Research Methods and Publication Outlets
(2011-10) WABWOBA, Franklin; IKOHA, Anselimo Peters
The multi-disciplinary nature of Information Technology has brought many methods of research with it. This has left many
Information Technology specialists whose background is from the rigid scientific disciplines in a dilemma. The paper
distinguishes Information Technology research from computer science research. It highlights where emphasis of research
in Information Technology needs to be placed. There has been a general shift in Information Technology from focus being
strictly technological to social, managerial and organizational in nature that have put demand on Information Technology
researcher to acquire knew skills. The paper differentiates the emphasis between Information Technology research and
computer science researcher. Both quantitative and qualitative approaches have become handy in this field of study. The
most common research methods action research, case study, Ethnography, experimentation, Grounded theory, secondary
method, and survey are discussed in this paper clearly giving the applicability. Important consideration and weakness of
each method from the information technology perspective are discussed in this paper. The findings outlets for the field are
also mentioned.
Green ICT Readiness Model for Developing Economies: Case of Kenya
(2013) Wabwoba, Franklin; Omuterema, Stanley; Wanyembi, Gregory W.; Omieno, Kelvin Kebati
There 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.
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, Franklin
The 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.
