Cloud SAMS: Cloud computing solution for public schools within South Africa's ‘second economy’

Published Conference ProceedingsCloud computing is coming of age; it involves on-demand access to a shared pool of configurable computing resources. There is an emerging consensus that cloud computing will play a critical role in redressing the digital divide especially in rural areas of Africa. In this paper, we report on a success story to this end; the use of cloud computing in expanding the access of students' records management system to resource-constrained schools in the Free State province of South Africa. This was motivated by the fact that despite the proven tight correlation between availability of data and quality of education, many schools that are considered part of the `second economy' in South Africa continue to operate in uni-direction data flow arrangements that do not provide them with adequate data for critical decision making. We implemented and evaluated a Cloud based School Administration and Management System; hereby called `Cloud SAMS' for these resource-constrained schools in the province (they account for over 80% of all schools). Starting off with 5 schools and later ramping it up to 50, `Cloud SAMS' enables schools to securely and privately share one copy of the system maintained in the cloud; this brings on board several benefits - low cost, faster implementation and resilience to failures

Awareness and Attitude towards Mango Infesting Fruit Flies and Adoption of an IPM Strategy: A Panel Data Analysis in Elgeyo Marakwet, Kenya

This study aimed at understanding farmers’ awareness and attitude towards mango infesting fruit flies, the adoption of an IPM strategy, and the determinants of farmers’ knowledge and perceptions on fruit fly infestation and management. We utilized panel data collected from 608 mango farmers in Elgeyo Marakwet County, Kenya. Descriptive results show that eighty four percent of farmers reported high damage caused by fruit flies. The most common identified fruit fly symptoms were infected fruits that contain maggots and fruits falling off the plant prematurely. Fruit fly traps and orchard sanitation by feeding infested fruits to animals and burying infected mangoes were well-known and adopted IPM strategies among the farmers. The principal component analysis (PCA) was employed to develop the knowledge and perception index that was subsequently used in multiple regression analysis. The regression estimates indicate that farmers’ awareness and attitude towards fruit fly infestation and management is positively associated with gender of the household head, training on IPM, contact with an extension officer, membership to a mango cooperative, and experience of pesticide intoxication, while age of the household head and mango income negatively influenced farmers’ awareness and attitude on fruit fly infestation and management. We emphasize on the role of rural institutions and associations in enhancing farmers’ knowledge and perceptions on fruit fly infestation and management through improved product-specific training, access to farmer cooperatives and extension services on non-pesticide methods of suppressing fruit flies.

Influence of Transformational Leadership on Performance of Housing Cooperative Societies in Nairobi City County, Kenya

Organizational performance is of great concern for it is the notch to which an enterprise attains its objectives in areas such as profitability, operational efficiency, liquidity levels and stakeholders’ satisfaction. Transformational leadership is about influence and this influence from an organization’s context should yield a positive outcome that enables bridge the gap of housing shelter needs in a country. The aim of the study was to determine the influence of human resource competences on performance of housing cooperative societies in Nairobi City County, Kenya. The research is anchored on the transformational leadership model and contingency theory. The study adopted cross-sectional descriptive research                      design. The target population of study was 418 housing co-operative societies in Nairobi City County, Kenya. Data was gathered using structured questionnaire issued to administrative manager or equivalent persons of each housing cooperative society. Data was analysed for both descriptive and inferential statistics and presented using frequency tables and percentages. The study established that there is significant relationship between transformational leadership and performance. This implies that an improvement in transformational leadership contributes significantly towards performance of housing cooperative societies in Nairobi City County Kenya. This demonstrates that delegation of work duties, employee promotion on merit basis, reward for good performance and discussion of performance appraisal results are all geared towards enhancing transformational leadership in housing cooperative societies. Organizations should embrace transformational leadership style since it instils innovativeness among employees hence enabling them to operate competitively in the globalized changing business market.

School Characteristics, Use of Project Method and Learner Achievement in Physics

The purpose of this study was to investigate how school characteristics affect the usage of the PM and the consequent impact on learner achievement in physics (LAP). Data was collected using Students Achievement Tests (SAT) and questionnaire for physics teachers. Stratified Sampling was applied to select 84 schools comprising boys, girls and mixed schools from seven provinces of Kenya. Statistical Package for Social Sciences (SPSS) was used to analyze the data. ANOVA, chi-square and multiple-regression were used to test the hypothesis. The key findings of the study were that PM enhances the learning of physics; Single sex schools performed better than mixed schools; the type of schools in terms of gender, whether day or boarding were not factors in the usage of project method. In view of these research findings, the researchers recommend that the government come up with a policy that enhances the establishment of more single sex schools, enhance resource mobilization for the teaching of physics, review the teacher training component so as to encompass the PM as an alternative teaching strategy, and in-service physics teachers on the role of school characteristics in the study of physics. Key words: Physics; Learner Achievement in Physics (LAP); Project Method PM; School Characteristics (SC)

Factors influencing smallholder farmers’ inputs use in major bean production corridors in Kenya

This study analysed socio-economic determinants for inputs use in major bean corridors in Kenya. It comprised 417 respondents sampled from four major bean corridors. A structured questionnaire was used in data collection. Probit model was used to assess determinants of input use among the bean-farming households. From the results, 74% of respondents were male with a mean age of 48.6 years. The probability of using agricultural inputs increased with education level and income from crop sales. Fertilizer was mainly used in Bomet (73%) and Narok (74%) counties. Eighty-five percent planted recycled seeds. Education level and Income from crops positively influenced inputs use. It was concluded that education level, incomes from sale of crops, livestock and livestock products, and farm income influenced use of inputs. As a recommendation, Capacity building on merits of input use and promotion of public-private partnerships to strengthen input supply system would enhance increased input use by smallholder farmers.Keywords: Bean, inputs, determinants, Keny

Comparison of CO2 capture by ex-situ accelerated carbonation and in in-situ naturally weathered coal fly ash

Natural weathering at coal power plants ash dams occurs via processes such as carbonation, dissolution, co-precipitation and fluid transport mechanisms which are responsible for the long-term chemical, physical and geochemical changes in the ash. Very little information is available on the natural carbon capture potential of wet or dry ash dams. This study investigated the extent of carbon capture in a wet-dumped ash dam and the mineralogical changes promoting CO2 capture, comparing this natural phenomenon with accelerated ex-situ mineral carbonation of fresh fly ash (FA). Significant levels of trace elements of Sr, Ba and Zr were present in both fresh and weathered ash. However Nb, Y, Sr, Th and Ba were found to be enriched in weathered ash compared to fresh ash. Mineralogically, fresh ash is made up of quartz, mullite, hematite, magnetite and lime while weathered and carbonated ashes contained additional phases such as calcite and aragonite. Up to 6.5 wt % CO2 was captured by the fresh FA with a 60% conversion of calcium to CaCO3 via accelerated carbonation (carried out at 2 h, 4Mpa, 90 o C, bulk ash and a S/L ratio of 1). On the other hand 6.8 wt % CO2 was found to have been captured by natural carbonation over a period of 20 years of wet disposed ash. Thus natural carbonation in the ash dumps is significant and may be effective in capturing CO2.Web of Scienc

How does adoption of labor saving agricultural technologies affect intrahousehold resource allocations? The case of push-pull technology in Western Kenya

Considerable research documents why women farmers have lower technology adoption rates than men farmers, but relatively little is known about what happens within a household after technology uptake. This study contributes through an investigation of the intrahousehold distribution of benefits and costs of agricultural technology adoption in western Kenya. Using gender-disaggregated data and an endogenous switching regression approach, we elucidate the causal effects of push pull technology (PPT) adoption on intrahousehold labor and expenditure allocation. Results show that adoption increases household labor allocation for harvesting of maize, the staple crop, but reduces the labor required for other tasks (e.g., ploughing and weeding). In net, the technology is labor saving, with men experiencing a slightly greater workload reduction than women. In terms of expenditure impacts, PPT uptake increases household expenditures on children’s education and consumption goods commonly associated with female preferences. Study findings support wider uptake of PPT to trigger gains in social and economic wellbeing for both men and women farmers. Implications for policy and practice are discussed

ANTIINFLAMMATORY PROPERTIES OF DICHLOROMETHANE: METHANOLIC LEAF EXTRACTS OF CAESALPINIA VOLKENSII AND MAYTENUS OBSCURA IN ANIMAL MODELS

Objective: Inflammation is the reaction to injury of the living tissues. Conventional medication of inflammation is expensive and arguably associated with various severe adverse effects hence the need to develop herbal agents that are effective as alternative. Caesalpinia volkensii and Maytenus obscura are plants that grow in Mbeere County of Eastern region of Kenya. This study was designed to evaluate the anti-inflammatory activity of C. volkensii and M. obscura plants. Methods: Experimental animals were divided in to four groups; normal group, diseased negative control group, diseased reference group and diseased experimental groups. Inflammation was inducted into the mice using carrageenan. The experimental groups were treated with leaf extracts of the plants at concentration of 50 mg/kg, 100 mg/kg and 150 mg/kg. Anti-inflammatory activities in rats were compared with diclofenac (15 mg/kg) as the standard conventional drug. Results: The leaf extracts of C. volkensii reduced the paw edema by between 6.50%-13.42% while the extracts of M. obscura reduced it by between 4.94%-22.36%. Diclofenac reduced the paw edema by between 4.11%-10.47%. Conclusion: The phytochemical screening results showed that the extracts of C. volkensii had flavonoids, steroids and phenolics while the leaf extracts M. obscura had phenolics, terpenoids and saponins. Flavonoids, saponins and phenolics have been associated with anti-inflammatory activities. Therefore, the study has established that the DCM: methanolic leaf extracts of Caesalpinia volkensii and Maytenus obscura are effective in management of inflammation

The role of gender on malaria preventive behaviour among rural households in Kenya

Malaria remains a major health and development challenge in the sub-Saharan African economies including Kenya, yet it can be prevented. Technologies to prevent malaria are available but are not universally adopted by male- and female-headed households. The study thus, examined the role of gender in malaria prevention, examining adoption behaviour between male- and female-headed households in Kenya
