Ill health and agricultural production: Evidence from Kogi State of Nigeria

This study was carried out to analyse the impact of ill health on agricultural outputs in rural areas of Kogi state, central Nigeria. The motivation derives from the fact that rural areas which are strategically important for national food security are more prone to health hazards as a result of the poor nature of health services arising partly from neglect by government. The objectives were to present the socioeconomic characteristics of the rural farm households and identify the prevailing health and agricultural  production nexus in the area. The use of multistage random sampling procedure was employed in the selection of 263 rural households for questionnaire administration in order to elicit relevant data related to their farming enterprises and health. The use of descriptive statistics and  production function analysis were employed. The study revealed that the  average age of the household heads was 46.4 years while the average household size was 6.5 persons. Also, the average farm size was 1.43 ha and the average number of years of formal education was found to be7.4. Furthermore, the study revealed that the most prominent disease conditions affecting farm families were malaria fever, typhoid fever and diarrhea and these led to an average of 8.2 days reduction in time  available for farm work in a farming season. Result from the production function analysis revealed that the elasticities of farm size (0.419), family size (0.099), number of contacts with extension staff (0.018), labour  (0.012) and naira amount of credit accessed (0.25) were positively signed and significant at 1%, 10%, 1%, 5% and 1% respectively; while number of days of farm work lost to ill health was negatively signed (- 0.09) and significant at 5%. Findings suggest that focusing on number of days of farming activities lost to ill health in a household might help elicit a clearer picture of the effect of transient ill health on agricultural production. More research and development effort in the provision of and accessibility to health care in the rural areas in order to reduce the incidence of diseases are recommended. Such efforts should also include the provision of adequate health and environmental education for the rural population as the most common ailments discovered in the study area are actually hygiene and environment related.Key words: Health, labour, rural, farm, outpu

Cancer mortality distribution in South Africa, 1997–2016

IntroductionThe mortality data in South Africa (SA) have not been widely used to estimate the patterns of deaths attributed to cancer over a spectrum of relevant subgroups. There is no research in SA providing patterns and atlases of cancer deaths in age and sex groups per district per year. This study presents age-sex-specific geographical patterns of cancer mortality at the district level in SA and their temporal evolutions from 1997 to 2016.MethodsIndividual mortality level data provided by Statistics South Africa were grouped by three age groups (0–14, 15–64, and 65+), sex (male and female), and aggregated at each of the 52 districts. The proportionate mortality ratios (PMRs) for cancer were calculated per 100 residents. The atlases showing the distribution of cancer mortality were plotted using ArcGIS. Spatial analyses were conducted through Moran's I test.ResultsThere was an increase in PMRs for cancer in the age groups 15–64 and 65+ years from 2006 to 2016. Ranges were 2.83 (95% CI: 2.77–2.89) −4.16 (95% CI: 4.08–4.24) among men aged 15–64 years and 2.99 (95% CI: 2.93–3.06) −5.19 (95% CI: 5.09–5.28) among women in this age group. The PMRs in men and women aged 65+ years were 2.47 (95% CI: 2.42–2.53) −4.06 (95% CI: 3.98–4.14), and 2.33 (95% CI: 2.27–2.38) −4.19 (95% CI: 4.11–4.28). There were considerable geographical variations and similarities in the patterns of cancer mortality. For the age group 15–64 years, the ranges were 1.18 (95% CI: 0.78–1.71) −8.71 (95% CI: 7.18–10.47), p < 0.0001 in men and 1.35 (95% CI: 0.92–1.92) −10.83 (95% CI: 8.84–13.14), p < 0.0001 in women in 2016. There were higher PMRs among women in the Western Cape, Northern Cape, North West, and Gauteng compared to other areas. Similar patterns were also observed among men in these provinces, except in North West and Gauteng.ConclusionThe identification of geographical and temporal distributions of cancer mortality provided evidence of periods and districts with similar and divergent patterns. This will contribute to understanding the past, present, future trends and formulating interventions at a local level

Analysis And Prediction Of Cost And Time Overrun Of Millennium Development Goals (MDGS) Construction Projects In Nigeria.

The paper focuses on the analysis and forecast of cost and time overrun of MDGs construction projects in Nigeria. Twenty five MDGs construction projects from (2006-2009) were critically investigated and time and cost overrun of the project were studied. The Statistical Package for Social Scientists (SPSS) 19.0 version was used to analyse the variables using Paired t-test and simple regression at 95% confidence limits. The analysis was based on the adaptation of requisition method. The validity test on the efficiency of the model was highlighted using the confidence interval to enhance the application of the models. Mathematical models were developed. The findings shows that there is a significant different between the total contract sum, cost overrun, total contract duration, and time overrun for the MDGS projects. The study suggests acute need for government to engage in proactive strategic planning and approaches to keep construction project cost and time within reasonable limit for the actualization of MDGs policy of development and environmental sustainability.   Keywords: Analysis and Prediction, Cost Overrun, Time Overrun, Millennium Development Goals and Construction Projects

Impact of health financing policies in Cambodia: a 20 year experience

Improving financial access to services is an essential part of extending universal health coverage in low resource settings. In Cambodia, high out of pocket spending and low levels of utilisation have impeded the expansion of coverage and improvement in health outcomes. For twenty years a series of health financing policies have focused on mitigating costs to increase access particularly by vulnerable groups. Demand side financing policies including health equity funds, vouchers and community health insurance have been complemented by supply side measures to improve service delivery incentives through contracting. Multiple rounds of the Cambodia Socio-Economic Survey are used to investigate the impact of financing policies on health service utilisation and out of pocket payments both over time using commune panel data from 1997 to 2011 and across groups using individual data from 2004 to 2009. Policy combinations including areas with multiple interventions were examined against controls using difference-in-difference and panel estimation. Widespread roll-out of financing policies combined with user charge formalisation has led to a general reduction in health spending by the poor. Equity funds are associated with a reduction in out of pocket payments although the effect of donor schemes is larger than those financed by government. Vouchers, which are aimed only at reproductive health services, has a more modest impact that is enhanced when combined with other schemes. At the aggregate level changes are less pronounced although there is evidence that policies take a number of years to have substantial effect. Health financing policies and the supportive systems that they require provide a foundation for more radical extension of coverage already envisaged by a proposed social insurance system. A policy challenge is how disparate mechanisms can be integrated to ensure that vulnerable groups remain protected

An Assessment of Environmental Impacts of Building Construction Projects

The environment is threatened severely by so many problems, some of which are caused by the activities of Construction Projects. The global concern to address environmental degradation caused by various developmental actions (construction projects inclusive) is the basis for calls to assess environmental impacts of building construction projects in Nigeria. Data for the study were collated through a questionnaire survey administered to stakeholders of Nigeria’s building construction industry. Data collected were analysed and ranked using Relative Importance Index (RII), result shows impacts listed are above the mid (RII) index of 3.0 suggesting that they significantly impact on the environment thereby causing environmental degradation. The research also reveals major environmental impacts of building construction projects to include environmental pollution, resource depletion and habitat destruction causing Destruction of ecosystem, Desertification, Soil Erosion and increasing Material Wastage. Waste Management, Pollution Control and Ecology Conservation were ranked as the most important environmental protection measures used in controlling building construction environmental impacts. The study therefore suggest that in order to reduce environmental degradation, building construction stakeholders must adopt fully environmental impact assessment document and other regulations relevant for environmental protection. Also, all environmental regulatory agencies and sensitization organizations should continuously sensitize the building construction public on requisite environmental management practice and sanction erring agents.

Assessment of Critical Stakeholders Conflict Factors on Tertiary Educational Trust Fund (TETFund) Building Construction Projects in Southwest Nigeria

Building construction project are complex, unique, and involved the use of multidimensional stakeholders to execute the project from the design stage through construction and completion. This leads to conflict and if not properly managed affects project performance. This study assessed critical stakeholders conflict factors on TETfund building construction projects performance in southwest Nigeria with a view to ameliorating the problems of dispute, non- performance and project abandonment. Qualitative research approach was adopted and a structured questionnaire was administered to three hundred and ninety-four (394) project stakeholders (client’s representative, consultants and contractors). Two hundred and ninety-seven (297) representing (75.38%) were retrieved from the respondents. The data collected was analyzed using both descriptive and inferential statistics. Mean Score (MS) was used to rank the level and effect of Stakeholders conflict on project performance while Kruskal-Wallis, Anova and LSD post hoc test was used to determine the convergence and divergent views of clients, consultants and contractors. The top three causes of conflicts on TETFund building construction projects are discrepancy between measured work and valuation, errors, discrepancies and omissions in contract documents and delay of task dependency activities. The top three effects of stakeholders conflict on project performance are poor quality of work executed, lag in construction programms and abuse of rule of engagement.  It is hereby recommended that discrepancy between measured work and valuation, errors and omissions in contract documents and delay of task dependency activities which are the major causes of conflict should be addressed to improve performance of TETfund building construction projects

Free health care for under-fives, expectant and recent mothers? Evaluating the impact of Sierra Leone's free health care initiative.

This study evaluates the impact of Sierra Leone's 2010 Free Health Care Initiative (FHCI). It uses two nationally representative surveys to identify the impact of the policy on utilisation of maternal care services by pregnant women and recent mothers as well as the impact on curative health care services and out-of-pocket payments for consultation and prescription in children under the age of 5 years. A Regression Discontinuity Design (RDD) is applied in the case of young children and a before-after estimation approach, adjusted for time trends in the case of expectant and recent mothers. Our results suggest that children affected by the FHCI have a lower probability of incurring any health expenditure in public, non-governmental and missionary health facilities. However, a proportion of eligible children are observed to incur some health expenditure in participating facilities with no impact of the policy on the level of out-of-pocket health expenditure. Similarly, no impact is observed with the utilisation of services in these facilities. Utilisation of informal care is observed to be higher among non-eligible children while in expectant and recent mothers, we find substantial but possibly transient increases in the use of key maternal health care services in public facilities following the implementation of the FHCI. The diminishing impact on utilisation mirrors experience in other countries that have implemented free health care initiatives and demonstrates the need for greater domestic and international efforts to ensure that resources are sufficient to meet increasing demand and monitor the long run impact of these policies

Changes in beverage purchases following the announcement and implementation of South Africa's Health Promotion Levy: an observational study

BACKGROUND: In 2016, South Africa announced an intention to levy a tax on sugar-sweetened beverages (SSBs). In 2018, the country implemented an SSB tax of approximately 10%, known as the Health Promotion Levy (HPL). We aimed to assess changes in the purchases of beverages before and after the HPL announcement and implementation. METHODS: We used Kantar Europanel data on monthly household purchases between January, 2014, and March, 2019, among a sample of South African households (n=113 653 household-month observations) from all nine provinces to obtain per-capita sugar, calories, and volume from taxable and non-taxable beverages purchased before and after the HPL announcement and implementation. We describe survey-weighted means for each period, and regression-controlled predictions of outcomes and counterfactuals based on pre-HPL announcement trends, with bootstrapped 95% CIs, and stratify results by socioeconomic status. FINDINGS: Mean sugar from taxable beverage purchases fell from 16·25 g/capita per day (95% CI 15·80-16·70) to 14·26 (13·85-14·67) from the pre-HPL announcement to post-announcement period, and then to 10·63 g/capita per day (10·22-11·04) in the year after implementation. Mean volumes of taxable beverage purchases fell from 518·99 mL/capita per day (506·90-531·08) to 492·16 (481·28-503·04) from pre-announcement to post announcement, and then to 443·39 mL/capita per day (430·10-456·56) after implementation. Across these time periods, there was a small increase in the purchases of non-taxable beverages, from 283·45 mL/capita per day (273·34-293·56) pre-announcement to 312·94 (296·29-329·29) post implementation. When compared with pre-announcement counterfactual trends, reductions in taxable beverage purchase outcomes were significantly larger than the unadjusted survey-weighted observed reductions. Households with lower socioeconomic status purchased larger amounts of taxable beverages in the pre-announcement period than did households with higher socioeconomic status, but demonstrated bigger reductions after the tax was implemented. INTERPRETATION: The announcement and introduction of South Africa's HPL were followed by reductions in the sugar, calories, and volume of beverage purchases.

Mathematics Applications for Agricultural Development: Implications for Agricultural Extension Delivery

This paper recognizes the fact that agriculture has been the mainstay of the nation’s economy as it provides food for the teeming population and raw materials for the industries. The obvious remains that mathematics application for the development of agriculture becomes imperative and worthwhile. The paper therefore focuses on the concepts of mathematics and agricultural development, its requirements as well as some arrays of mathematics applications for agricultural development. Finally, it is suggested that the extension delivery of new technological packages should be participatory and democratic enough to allow farmers avail themselves the opportunities of identifying their needs and problems, prioritizing them, analyzing them, among other commitments.Key words: Mathematics, Application, Agricultural development, Extension deliver
