An exploration of women's transformation through distance learning in Kenya.

Thesis (Ph.D.) - University of KwaZulu-Natal, Durban, 2004.This research, An Exploration of Women's Transformation through Distance Learning in Kenya, applied Mezirow's theory of transformative learning to investigate how distance learning impacted on women's views about themselves and their position in society. This was done by examining whether distance learning enables women to acquire new self-perceptions about themselves and leads them to challenge the status quo and take action in order to improve their status in society. Three distance learning programmes were studied: the B.Ed. programme at the Faculty of External Studies at the University of Nairobi, Theological Education by Extension, and the Co-operative College of Kenya. This research was motivated through my own biography, with the purpose of identifying and encouraging distance learning practices that promote women's transformation. The research also hoped to draw attention to the study of women's issues in distance learning, as an area that has not attracted much attention in Kenya and to generate information which can be used to inform the use of distance learning methods in a way that favours women. Biographical methods of research were used. This involved listening to women's learning stories, noting their reasons for coming back to study, the barriers that they encountered as they studied and the coping strategies that they used to overcome the barriers. In addition, other methods were used to supplement the biographical data collected from the women. These included focus group discussions, observation and documentary evidence. The approach to data analysis was based on the use of hermeneutics methods of data interpretation. The themes and concepts that emerged from this process were compared with themes and concepts generated through other methods of data collection. The main findings were that distance learning, though based on alternative forms of provision, does lead to transformation, however, women from the three programmes experienced diverse levels of transformation. The B.Ed.programme with its face-to-face component and women with higher education had greater impact on women's transformation than other programmes. Although the TEE programme had face-to-face interaction, their curriculum, which reinforced the negative gender stereotypes in society and does not lead to recognised certificates, could not allow them to achieve this experience. The Coop programme, without the face-to-face arrangement had the lowest transformative effects on women. On the basis of these findings, it was recommended that more distance learning programmes be designed, with increased use of face-to-face components in order to help women achieve transformation. The findings and the discussions thereof also show that prior level of education had far reaching effects on the levels of transformation that women achieved. This led to the recommendation that women's education should be encouraged and the society should be sensitised about the value of educating women. Distance learning also enabled women to achieve economic empowerment, in terms of promotions, new jobs and increased salaries; however this was only noted in the B.Ed. and Coop programmes. The TEE programme, being a church programme had no economic benefits for its women learners. The women in the TEE programme were not happy with the present arrangement and were, therefore, calling for a review of the programme. The findings also showed that women's transformation is not being fully achieved because of non- supportive facilities and the use of learning materials, which reinforce the negative gender stereotypes in society. Therefore, to make distance learning more accessible to women learners and more transformational, the research recommended changes geared towards the creation of women-friendly facilities and learning materials

Studies on the interaction of Schistosoma mansoni and Leishmania major in experimentally infected Balb/c mice

Schistosoma mansoni and Leishmania major are important tropical human parasites. It is crucial to know the effect of the two infecting man concurrently. Two groups of BALB/c mice were infected with each of the parasites separately; another group was co-infected with both parasites and there was a naïve control. Draining lymph node and spleen cells from mice infected with either of the parasites showed high proliferative responses to their specific parasite antigen. However, crossreactivity occurred between S. mansoni and L.a major. Spleen and Lymph node cells from co-infected group demonstrated high and sustained proliferative responses to schistosome soluble worm antigen preparation and killed Leishmania major antigen, respectively. There was high and sustained IgG levels for both the single and coinfected groups. At 10 weeks post-infection, co-infected mice had significantly larger nodules than mice with L. major infection alone. However, co-infected animals had less severe liver pathology and less enlarged mesenteric lymph nodes than those infected with S. mansoni only. This work shows that co-infection results in two different outcomes: protection against S. mansoni and exacerbated pathogy in L. major. We suggest that cellular responses possibly protect against S. mansoni , while high IgG levels lead to exacerbated L. majorresponse. African Journal of Health Sciences Vol. 14 (1-2) 2007: pp. 80-8

The effect of vaccinating S. mansoni–infected BALB/c mice either before or after treatment

In Schistosoma mansoni endemic areas, there are people with ongoing S. mansoni infection, others have been infected and treated while others have never been infected. What would happen if these different groups of people were vaccinated against S. mansoni? BALB/c mice were divided into five groups: Infected-Treated-Vaccinated; Infected-Vaccinated-Treated; Vaccinated-Treated Control; Challenge Control and Untreated challenge Control. Vaccination (500 20krad irradiated S. mansoni cercariae), Treatment (praziquantel), Infection and Challenge (150 S. mansoni cercariae) were carried out at specified times. Proliferation assay, Enzyme linked immunosorbent assay, gross pathology, histopathology and perfusion were performed. High protection levels were obtained in mice treated after vaccination: Vaccinated-Treated control, 96.5%; Infected-Vaccinated-Treated, 68.9%; and Infected-Treated-Vaccinated, 41%. A good correlation was obtained between proliferative responses and protective levels, implying cellular involvement in protection. Although all protected animals had high IgG levels, there was no strong correlation between the two. Specificity rather than amounts of IgG, seem more important in protection. Praziquantel seemed to boost protective immunity when administered after vaccination. Granuloma development and modulation in the two test groups was similar. It seems better to vaccinate infected patients before treatment, the ideal situation being vaccinating people who have not encountered S. mansoni.

ASSESSMENT OF THE EFFECTS OF BUSINESS ETHICS ON EMPLOYEES’ PERFORMANCE IN AGRICULTURAL FIRMS IN KENYA: A CASE OF GREENLANDS AGRO PRODUCERS LIMITED, NAIROBI

The purpose of the study was to establish the effects of business ethics on employee’s performance. This study was based at Greenlands Agro producers Limited, Nairobi. The objective of the study was to determine the effect of legal responsibilities, organizational loyalties, technical morality and personal responsibilities on employees’ performance in agricultural firms in Kenya. In literature review, the study adopted theories comprising of virtue ethical theory, social learning theory and finally the social exchange theory. In the methodology, the study adopted descriptive research design. The study targeted 48 respondents. There was no sampling; instead, the study adopted census design. The data was collected by use of questionnaires which was administered to respondents. The data was then analyzed by use of percentages and frequency tables. Then the data was presented in tabular and graphical format. The study addressed the need for an organization where people would be treated equally and a situation where every action is judged on a consistent and fair basis. It aims at providing available knowledge on how to initiate and develop appropriate ways of practicing business ethics. The summarized findings were drawn from the study that sought to establish the effect that legal responsibility as part of business ethics had on employee performance. From the findings, it was established that majority of respondents were in support that the company had to familiarize with external issues governing the industry it operates within. The study recommends that the management of Greenlands Agro Producers Limited had a responsibility to ensure that all legal regulations were observed and fully adhered to. Being agricultural firm, it was expected that more efforts were required to ensure that regulations that entailed proper environmental practices are fully followed. The study recommends that management has a responsibility to communicate to employees and enforce some moral sense in order to encourage proper business ethics. Adequate effort should be channeled towards encouraging employees to follow rules and regulations that govern operations within the organization

Influence of Prices on Market Participation Decisions of Indigenous Poultry Farmers in Four Districts of Eastern Province, Kenya

Over 70% of the domesticated birds in Kenya are indigenous chicken (IC) providing meat and table eggs. They are frequently raised through the free range, backyard production system. Small flock sizes are characteristic of this production system and often, sales are mainly at the farmgate. Although IC production possesses enormous potential at livelihood improvement, marketing systems are undefined and variable. The influence of prices on market engagement has frequently been assumed. A study of 68 farmers conducted in Machakos, Kibwezi, Nzaui and Mwala District in 2008 revealed that 70% of all IC sales were conducted at the farmgate while only 19% of the sales were at the local market. This study also investigates the probability of market participation by employing a binary logistic regression model. The results suggests that while farmers complain of poor farm gate prices for indigenous chicken offered by middlemen, low volumes are an important drawback to market participation

Factors influencing Adoption of Irrigation Technologies among Smallholder Farmers in Machakos County, Kenya

The study examined the factors that drive decisions to adopt and use irrigation technologies among smallholder farmers in Machakos County, Kenya.  Data were collected from a sample of 300 smallholder farmers.  Cross-sectional survey design, a multistage sampling procedure and random sampling method were employed. Percentages, means and econometric analysis were used in data analysis. Results showed that, 31.7% of the respondents practiced irrigation. Sex of household head, education, farm size, off-farm income, credit accessed and access to extension services positively influenced adoption of irrigation technologies. Adoption intensity was positively influenced by gender, off-farm income, farming experience, primary occupation and extension services. As a result, it is suggested that while formulating development strategies and programs for smallholder farmers, agricultural extension organizations should give priority to these factors.

Influence of Age of Mice on the Susceptibility to Murine Schistosomiasis Infection

Intensity of human schistosomiasis infection increases with age, a peak being attained at early puberty. Hormones could be involved in the age-related changes in susceptibility to schistosomiasis. Male BALB/c mice were infected with Schistosoma mansoni either before or after puberty and worm numbers, cellular immune responses, hormonal levels and pathology analysed. Pre-puberty infected mice had a significantly higher number of adult worms (p<0.05), more severe granulomas, higher mortality rate and higher proliferative responses as compared to postpuberty infected mice. Levels of the hormones were lower in the pre-puberty infected mice as compared to the post-puberty group early in the infection. Plasma levels of testosterone and luteinizing hormones decreased significantly (p<0.05) in infected mice when compared to controls. Susceptibility to S. mansoni in male BALB/c mice seems to be influenced by levels of testosterone and leutenizing hormone at infection. Albeit, an infection with S. mansoni seems to lower the hormonal levels
