Production of Electrical Porcelain Insulators from Local Raw Materials: A Review

This paper reviewed the production of electric porcelain insulators utilizing from local raw materials from developing countries. The raw materials used were feldspar, quartz/silica and kaolin. The chemical composition, mineralogy, and thermal properties of the raw materials were characterized using AAS, XRD, and TGA respectively. Different weight percentage combinations of the individual raw materials were investigated by the authors. Most of the results showed relatively acceptable porcelain insulators properties such as low water absorption, porosity, high insulation resistance, dielectric strength and bulk density. The paper showed that electric porcelain insulators with good properties can be produced from available local raw materials in some developing countries using appropriate formulations. However, for production of improved porcelain insulators properties, suggestions were made on the areas for future research

How decentralisation influences the retention of primary health care workers in rural Nigeria

Background: In Nigeria, the shortage of health workers is worst at the primary health care (PHC) level, especially in rural communities. And the responsibility for PHC – usually the only form of formal health service available in rural communities – is shared among the three tiers of government (federal, state, and local governments). In addition, the responsibility for community engagement in PHC is delegated to community health committees. Objective: This study examines how the decentralisation of health system governance influences retention of health workers in rural communities in Nigeria from the perspective of health managers, health workers, and people living in rural communities. Design: The study adopted a qualitative approach, and data were collected using semi-structured in-depth interviews and focus group discussions. The multi-stakeholder data were analysed for themes related to health system decentralisation. Results: The results showed that decentralisation influences the retention of rural health workers in two ways: 1) The salary of PHC workers is often delayed and irregular as a result of delays in transfer of funds from the national to sub-national governments and because one tier of government can blame failure on another tier of government. Further, the primary responsibility for PHC is often left to the weakest tier of government (local governments). And the result is that rural PHC workers are attracted to working at levels of care where salaries are higher and more regular – in secondary care (run by state governments) and tertiary care (run by the federal government), which are also usually in urban areas. 2) Through community health committees, rural communities influence the retention of health workers by working to increase the uptake of PHC services. Community efforts to retain health workers also include providing social, financial, and accommodation support to health workers. To encourage health workers to stay, communities also take the initiative to co-finance and co-manage PHC services in order to ensure that PHC facilities are functional. Conclusions: In Nigeria and other low- and middle-income countries with decentralised health systems, intervention to increase the retention of health workers in rural communities should seek to reform and strengthen governance mechanisms, using both top-down and bottom-up strategies to improve the remuneration and support for health workers in rural communities

Perceptions of patent and proprietary medicine vendors and communities of the tiered accreditation programme for family planning services in Lagos and Kaduna states, Nigeria

This study evaluated the perception of patent and proprietary medicine vendors (PPMVs) of the accreditation programme to improve their capacity to provide family planning (FP) services in Lagos and Kaduna, Nigeria. A cross-sectional mixed-method approach among 224 PPMVs was used to investigate their perception, willingness to pay for and adhere to the programme, its benefits, and the community women’s perception of the value of PPMVs. Chi-square analysis and structural equation modelling (SEM) were used to analyse survey data, while focus group discussions (FGDs) were analysed using the grounded theory. PPMVs were enthusiastic because of the benefits, including increased clientele, revenue, and improved service provision capacity. Approximately 97% of PPMVs found the programme acceptable and were willing to pay, with 56% and 71% willing to pay between N5000-N14900 ($12–36) and N25000-N35000 ($60–87), respectively. A significant relationship between educational attainment, location, and willingness to pay was revealed. Among community women, the fear of side effects, lack of partners’ support, myths and misconceptions, and lack of access to modern contraceptives were factors affecting contraceptive uptake. The capacity of PPMVs to improve FP uptake is promising and can be leveraged to improve health outcomes in communities while strengthening their businesses
