Abstract

This paper reviewed the period between 1975 and 1995 when World Bank funds were used to reactivate the erstwhile moribund extension services in Nigeria. It noted that significant progress had been made in the establishment of an institutional framework for a functional extension service in the country. There were, however, some weak areas that require special attention for the extension services to remain functional and relevant to the needs of a majority of farmers. These areas include the input supply system, the need for a special focus on issues of natural resources management for sustainable land use and the environment. Others are the need for democratization and empowerment of local communities and farmers’ associations, and the harnessing NGO efforts for a wider coverage and sustainability of the extension services. It was concluded that the big challenge in the next decade would be in the areas of securing government commitment and mobilizing local funds for sustaining the service.

Students working part-time while studying for a full-time university degree are commonplace in many Western countries. This paper, however, examines the historically uncommon part-time working activities and career aspirations among Nigerian university students. In particular, how working is perceived to contribute to developing employability skills, and whether it is influenced by their self-efficacy. Survey data from 324 questionnaires were collected from a federal university, although the data analysis used a mixed method. The findings indicate that despite low levels of part-time working generally among students, older, more experienced, higher level and female students place a premium on the skills that part-time work can develop. Moreover, self-efficacy and being female is a significant predictor in understanding part-time work and career aspirations. This study offers originality by focusing on students’ part-time work, the value working provides and its link with career aspirations, within a relatively unexplored context of Nigeria.  相似文献

The response of liver lipid peroxidative and antioxidant defense system of protein undernourished rats to liver regeneration induced by partial hepatectomy was examined in rats. Animals were divided into four groups; A,B,C and D of four animals each. Animals in group A were maintained on 16% casein diet while those in groups B, C and D were placed on low-protein diet (5% casein) for fourteen weeks and fed ad libitum. 72 hours before sacrifice, partial hepatectomy was carried out on animals in group D while animals in group C were sham-operated. The results show that protein undernutrition induced an increase in lipid peroxidation but reduced catalase activity, glutathione level and superoxide dismutase activity when compared with well-nourished rats. Liver regeneration however, resulted in significant increases in lipid peroxidation and catalase activity but significant reductions in glutathione level and superoxide dismutase activity in protein undernutrition rats when compared with their sham-operated counterparts. These results suggest that liver regeneration induced by partial hepatectomy exacerbates lipid peroxidation in protein undernutrition rats and that Catalase plays a major role in the mopping up of reactive oxygen species generated following liver regeneration in partially hepatectomised protein undernutrition rats.  相似文献

This study examines the policies and occurrences of occupational health hazards among library personnel in private universities in the Southwest, Nigeria. A total population of 177 respondents from 15 privately owned universities were used for the study. The research instrument used in the collection of data was a questionnaire. The result of the study shows that most respondents have experienced occupational health hazards. The study also revealed that muscle strain, back aches, eye problems, and respiratory diseases are the most prevalent occupational health hazards experienced by library personnel. The study identified manual handling of library materials, constant exposure of the eyes to computer screens, inhaling of chemicals and dust, as well as long sitting position as the main causes of occupational health hazards among staff. Most respondents indicated that their organizations are not implementing policies on occupational health hazards. Recommendations were made on how to address the various issues raised.  相似文献

Miscarriages, stillbirths, and infant loss are a constant threat to Nigerian women. Little research has sought to understand the cultural silence and taboo that typifies these issues needs and its impact on the women. Drawing on 35 in-depth interviews with Nigerian women, this study explored the sociocultural understanding of perinatal loss among Nigeria women. A thematic analysis of the women’s narratives indicated that cultural norms and practices contribute to disenfranchised grief, which translates into ridicule and blame for women, identity loss, marital instability, and a feeling of despair. The findings point to a need for more empirical research into the grieving processes of diverse populations. Theoretical and practical implications are discussed.  相似文献

The spread of soccer viewing centres (SVCs) in Nigeria is one of the unfolding legacies of global sporting media in Africa. While, providing access to live broadcast of European soccer competitions, SVCs have developed into supplementary social spaces where culturally defined rules of social relations are contested. Using Goffman's notion of performance and Agbalagba in Yoruba normative system, in conjunction with sociological perspective on space, the study explores the context and processes in the transformation of age social relations in Ibadan, South-Western Nigeria. Data were obtained through participant observation, and 23 in-depth interviews with viewing centre owners and soccer fans. Findings depict the SVC as a constructed space, with conflicting meanings, attitudes and practices, which inadvertently fracture and render fluid, the expectations of norms of age social relations. In conclusion, European soccer drives the spread of supplementary social spaces which impact local social structures in critical ways.  相似文献

The effect of caffeine intake on the risk of coronary heart disease was studied. Twenty-one rats used were randomly divided into three experimental groups, the first group served as the control while the second and third groups were administered caffeine orally at doses of 10mg/kg body weight and 20mg/kg body weight respectively for fourteen days. Caffeine, at 10mg/kg body weight, significantly increased (P<0.05) serum LDL- cholesterol concentration and coronary heart disease risk ratio while it significantly reduced (P<0.05) serum triacylglycerol concentration when compared with controls. At 20mg/kg body weight, caffeine significantly increased (P<0.05) coronary heart disease risk ratio while it significantly reduced (P<0.05) serum HDL-cholesterol concentration and serum triacylgycerol concentration when compared with controls. No dose response effect was observed possibly suggestive of a threshold effect. These results suggest that caffeine predisposes consumers of caffeine containing beverages to coronary heart disease.  相似文献
