Item Effectiveness of albendazole on soil transmitted nematodes among school children-: a case of Kakamega County, Kenya(2019-03-25) Ngonjo, T.W.; Okoyo, Collins; Simiyu, Elses; Kihara, Jimmy; Lelo, Agola Eric; Kabiru, Ephantus; Mwandawiro, CharlesBackground: Recent assessment by WHO on Soil Transmitted Nematodes (STN) point that their morbidity is still high in people mainly in children. A. lumbricoides globally infects 1.2 billion people and T. trichiura 795 million worldwide. Infections with Ancylostoma duodenale and Necator americanus 740 million leading to 135,000 deaths per year. It became necessary to find out the effectiveness of Albendazole on soil transmitted Nematodes among school children- a case of kakamega county, kenya. Methodology: Study respondents were selected fom public primary school children in Kakamega County. A total of 731 and 665 (pre & post) children in 7 primary schools in three sub counties of Kakamega County were recruited in the study. Pre-treatment survey was done in March, 2014 and follow up in September 2014. Fecal samples were examined for the presence of STN . 14 days after treatment using Kato- Katz method. The total number of eggs were expressed as eggs/gm of feaces (epg). Pretreatment prevalence was 43.5% for Ascaris lumbricoides, 1.8% for hookworm and 0.9% for Trichuris trichiura. Results: Mean intensity of hookworm, A. lumbricoides and T. trichiura infections in the pre-and post-surveys were reduced by 1.2%, 98.4% and 100% respectively. Prevalence decreased to 2.3% for Ascaris lumbricoides and 0 % for T. trichiura. Post treatment prevalence of A. lumbricoides and T. trichiura infections were significantly reduced by 94.8% and 100% respectively. A slight increase in hookworm prevalence was observed. However, this increase was not significant (p=0.993). Conclusion: The therapeutic efficacy of Albendazole indicated a good reduction in parasite burden. Albendazole satisfactorily reduced STN infection while for hookworm there was a non-significant increase in prevalence.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 Exploring Resources and Performance Relationships in Commercial Enterprises: An Empirical Perspective(2015-10-07) Ombaka, Beatrice Elesani; Awino, Zachary Bolo; Machuki, Vincent N.; Wainaina, GituroDespite a growing body of literature on firm performance, explaining why firms in the same industry and markets differ in their performance remains a fundamental question within strategic management field. Researchers have attributed differences in firm performance to resources owned by a firm but the results remain fragmented and no consensus has yet emerged. Therefore, the debate is still open and this study sought to contribute to the debate and address extant gaps. This study investigated the influence of organizational resources on performance of insurance companies in Kenya. The study was based on a survey of 46 insurance companies in Kenya. The study reports that both tangible and intangible resources have a statistically significant influence on non-financial performance of insurance companies in Kenya. However, there were mixed findings as regards the individual influence of resources on various firm performance indicators. Intangible resources evidenced statistically not significant results individually but when combined, they had a statistically significant influence on non-financial performance. The reverse was true for tangible resources. Based on the findings, implications of the study and suggestions for further study are presented.Item Exploring Resources and Performance Relationships in Commercial Enterprises: An Empirical Perspective(2015-10-07) Beatrice E., Ombaka; Awino, Zachary Bolo; Machuki, Vincent N.; Wainaina, GituroDespite a growing body of literature on firm performance, explaining why firms in the same industry and markets differ in their performance remains a fundamental question within strategic management field.

It is common to find that morphologically similar cultivars do not bear the same name while cultivars bearing the same name may not be identical morphologically. The aim of this study was to clear the ambiguity that exists in differentiating between the various phenotypes of Lablab. The morphological method is the oldest and considered the first step in description and classification of germplasms. Forty five accessions of Lablab collected from farmers’ fields in Rift Valley, Eastern, Coast and Central regions of Kenya were planted at Kenya Agricultural and Livestock Research Organization, Njoro farm. A descriptor from Asian Vegetable Research Development Center was used as a guide. Results on means separation showed a high level of variability in quantitative traits and a low level of variability in qualitative traits. Eigen vectors derived from principal component analysis indicated that seed yield per plant, number of pods per plant, plant height and days to 90% mature pods contributed highly to total diversity in Lablab. In conclusion, Lablab germplasm grown in Kenya is morphologically diverse in quantitative traits where different genotypes are distinctly dissimilar.Item Research data management challenges in Kenya: the case of private universities in Nairobi County(2019-09) Anduvare, E. M.; Mutula, S. M.This research paper is a spinoff from a Doctoral degree study that was carried out at the University of KwaZulu-Natal between 2017-2019. The aim of the study was to establish the role private university libraries in Nairobi, Kenya play in supporting eResearch and the challenges thereof that librarians and researchers face in the process of managing data. The study employed both qualitative and quantitative epistemological approaches with semi structured interviews and survey questionnaires to collect data from a population consisting of university librarians, faculty members and doctoral students respectively. The population was sampled purposively. The qualitative and quantitative data sets were analysed using SPSS and content analysis respectively. The findings revealed several challenges, which included among others the lack of strategies and policies to guide research data management support, the lack of integrated RDM policies, a research process that was fragmented, and limited ICT policies and infrastructures. The institutionalisation of RDM in the private universities in Kenya is therefore urgent and imperative. The findings have policy, practical and theoretical implications for the effective RDM in Kenyan private universities in order to enhance scientific and scholarly communications. While the focus of the study limits generalisation of the findings, other universities may gain insights on RDM challenges within university settings.Item Relationship between empathy dimension and customer satisfaction in the insurance industry in Kenya(2019-10) Chege, Catherine Njoki; Wanjau, Kenneth Lawrence https://orcid.org/0000-0002-3146-5324; Nkirina, SeverinaThe Insurance industry is essential to the economic course of every nation attaining sustainable growth and prosperity. However, the industry continues to experience a marginal growth of 2.5% compared to the global real term growth of 4%. This study analyzed the relationship between employee empathy and customer satisfaction in the Kenyan insurance industry. The study was guided by the causal research design. The study applied the linear mixed-effect models of structural equation modeling (SEM) considering the multi-level structure of the data collected. The study concluded that a client who perceives empathy from his/ her insurer’s employees is bound to have higher satisfaction than a customer who does not perceive empathy from their insurer. Employee empathy however, does not significantly affect the variations of customer satisfaction between the insurance companies.Item The Impact Of Policy Changes In The Education Sector On The Development Of The Book Publishing Industry In Kenya(Unisa Press, 2009) Mbengei, Bernard; Francis, GallowayThis article explores the impact of policy changes in the education sector on the de-velopment of the book publishing sector in Kenya. The article begins by detailing the current status of the book publishing sector in Kenya. Then the interdependence between the education and book publishing sectors is highlighted. The government policies that have shaped the education system in Kenya are analysed with a view to establishing how they have affected the book publishing sector. An overview of the new school textbook policy that was introduced in 1998 is presented in order to show how it has influenced the textbook production and procurement. Then the introduction of the Free-Primary Education (FPE) is discussed because it is the most recent development in the education sector that has provided tremendous impetus to the development of the book publishing industry in the country. The challenges encountered by the Government of Kenya in implementing the FPE and those faced by the book publishers in producing books for the school market are analysed. Finally, a way forward is proposed in the form of recommendations that can contribute to positive growth and mainstreaming of the school textbook publishing sub-sector in Kenya. A literature review approach isused in which sources that include newspapers, government and institutional websites, journals, books and dissertations have been consulted.Item Effects of blended fertilizers on soil chemical properties of mature tea fields in Kenya(2018-06) Sitienei, Kibet; Kamiri, Hellen W.; Nduru, Gilbert M.; Kamau, David M.Kenya’s tea industry depends predominantly on imported NPK fertilizers to replenish nutrients removed through plucking. In this respect, two blended fertilizers containing NPKS 25:5:5:4+9Ca+2.6Mg and NPKS 23:5:5:4+10Ca+3Mg with trace elements have been produced in the country. However, contribution of the blended fertilizers to optimal tea yields had not been determined. The study aimed to evaluate the optimal levels of the two blended fertilizers on tea grown in the highlands of Kenya. The blended fertilizers were evaluated in two sites, i.e. Timbilil estate in Kericho and Kagochi farm in Nyeri. The trial was laid out in a randomized complete block design with two blended fertilizers and the standard NPK 26:5:5 as a control. The treatments were applied at four fertilizer rates (0-control, 75, 150 and 225 kg N ha-1 yr-1), with three replications. The results showed that application of 225 kg N ha-1 yr-1 blended fertilizer NPKS 25:5:5:4+9Ca+2.6Mg in Timbilil produced mean yield of 2,995 kg Mt ha-1 compared with 3,099 kg Mt ha-1 from the standard NPK. In Kagochi, the highest yield was 1,975 kg Mt ha-1 obtained from the application of the same blended fertilizer NPKS 25:5:5:4+9Ca+2.6Mg at 75 kg N ha-1 yr-1. The highest yields in both sites were obtained during a warm-dry season except in 2015–2016. This study concluded that based on the annual and seasonal yields, the two blended fertilizers and the standard type had the same effectiveness, irrespective of clones and sites. However, the fertilizer rates affected the tea yield.Item EFFECTS OF BLENDED FERTILIZERS ON YIELDS OF MATURE TEA CLONES TRFK 6/8 AND BBK 35 GROWN IN KENYAN HIGHLANDS(2018-08) Sitienei, Kibet; Kamiri, Hellen Wangechi Kamiri; Nduru, Gilbert M.; Kamau, DavidKenya’s tea industry depends predominantly on imported NPK fertilizers to replenish nutrients removed through plucking.
