Industrial Applications of Clay Materials from Ghana - A Review

Clay minerals are phyllosilicate groups naturally found in soils in all parts of the world. They have proven to be among the most essential industrial minerals because of their unique physicochemical properties and versatile applications within a wide range of fields including ceramics, construction, and environmental remediation, biomedical as well as cosmetics. Clay minerals are also primary to the production of other materials such as composite for secondary applications. In Ghana, clay mineral deposits are commonly found in several areas including soil horizons as well as geothermal fields and volcanic deposits, and are formed under certain geological conditions. This review seeks to explore the geographical occurrence and discusses the current uses of various local clay materials in Ghana in order to highlight opportunities for the utilization of these materials for other applications.

Industrial manufacture of sugar-free chocolates - Applicability of alternative sweeteners and carbohydrate polymers as raw materials in product development

Chocolate is dense suspension of solid particles comprising 60-70% sugar and non-fat cocoa solids. Until recently, it was rarely produced as a sugar-free product due to the multi-functional properties of sweetness, bulkiness and textural characteristics that sugar offers to products. Today's consumers are concerned about the high sugar levels, calories and cariogenicity effects in confectionery products, hence increasing popularity of 'light' and 'sugar-free' products. Development of sugar-free chocolates is most challenging since all sugar needs to be replaced. In-depth understanding of the applicability of alternative sweeteners and carbohydrate polymers as ingredients in sugar-free chocolate manufacture would therefore have significant industrial applications. © 2013 Elsevier Ltd.

Industrial policy in Ghana: Its Evolution and Impact

This chapter chronicles the evolution of industry in Ghana over the post-independence era from an inward overprotected ISI strategy of 1960–83 to an outward liberalized strategy during 1984–2000, and since 2001, to the private sector-led accelerated industrial development strategy based on value-addition. Industry in Ghana is mainly dominated by micro and small firms, privately owned and mainly located within urban areas in the form of industrial clusters. Patterns of labour productivity and wages indicate the food processing sub-sector, foreign owned and older firms as the most productive. The emerging policy issues from Ghana’s current industrial policy include how to empower SMEs to expand productive employment and technological capacity within a highly competitive manufacturing sector; how to promote agro-based industrial development to ensure value-addition to manufactures and Ghana’s exports among others.

Industrialisation for structural transformation in Africa: Appropriate roles for the state

The majority of African countries recognise the need for structural transformation. They acknowledged this need very early after attaining independence some five decades ago. Unfortunately, such transformation has eluded them while success has been observed in many parts of East Asia. There are obvious questions to be asked about the different outcomes observed. In trying to find explanations for the different outcomes, the literature shows that a major difference has been the role and capabilities of the state. While the state pursued transformation through industrial policy in a systematic way in many East Asian countries, such a systematic approach has not been observed in most parts of Africa. It is obvious that African countries can learn some principles from East Asia in the pursuit of structural transformation. They can set clear goals for transformation and develop clear strategies for achieving the goals. They can also assign specific roles to institutions and individuals in the implementation of strategies. But most importantly, they must show commitment to industrial policy and stick with the agreed policies, making periodic modifications and adjustments when necessary. In choosing goals for industrial policy, African governments cannot lose sight of current capabilities and endowments. They must be guided by how they want to be positioned in a changing global economy. This is what will drive them to develop specific policies that can make them replace fast-growing East Asian economies, such as China, as they move on to other levels in their transformation. In choosing strategies, African countries need to accept that it is not simply a case of 'government versus market'. Nor is it 'horizontal versus vertical industrial policies'. They will find that 'import-substitution versus export promotion' is no longer a dichotomous issue. Being pragmatic and consistent after making the right choices is the way forward. © The author 2012. Published by Oxford University Press on behalf of the Centre for the Study of African Economies.

Inequalities in access to education and healthcare

The burden of disease is borne by those who suffer as patients but also by society at large, including health service providers. That burden is felt most severely in parts of the world where there is no infrastructure, or foreseeable prospects of any, to change the status quo without external support. Poverty, disease and inequality pervade all the activities of daily living in low-income regions and are inextricably linked. External interventions may not be the most appropriate way to impact on this positively in all circumstances, but targeted programmes to build social capital, within and by countries, are more likely to be sustainable. By these means, basic oral healthcare, underpinned by the primary healthcare approach, can be delivered to more equitably address needs and demands. Education is fundamental to building knowledge-based economies but is often lacking in such regions even at primary and secondary level. Provision of private education at tertiary level may also introduce its own inequities. Access to distance learning and community-based practice opens opportunities and is more likely to encourage graduates to work in similar areas. Recruitment of faculty from minority groups provides role models for students from similar backgrounds but all faculty staff must be involved in supporting and mentoring students from marginalized groups to ensure their retention. The developed world has to act responsibly in two crucial areas: first, not to exacerbate the shortage of skilled educators and healthcare workers in emerging economies by recruiting their staff; second, they must offer educational opportunities at an economic rate. Governments need to lead on developing initiatives to attract, support and retain a competent workforce. © 2008 Blackwell Munksgaard and The American Dental Education Association.

Inequalities in child immunization coverage in Ghana: evidence from a decomposition analysis

Childhood vaccination has been promoted as a global intervention aimed at improving child survival and health, through the reduction of vaccine preventable deaths. However, there exist significant inequalities in achieving universal coverage of child vaccination among and within countries. In this paper, we examine rural-urban inequalities in child immunizations in Ghana. Using data from the recent two waves of the Ghana Demographic and Health Survey, we examine the probability that a child between 12 and 59 months receives the required vaccinations and proceed to decompose the sources of inequalities in the probability of full immunization between rural and urban areas. We find significant child-specific, maternal and household characteristics on a child’s immunization status. The results show that children in rural areas are more likely to complete the required vaccinations. The direction and sources of inequalities in child immunizations have changed between the two survey waves. We find a pro-urban advantage in 2008 arising from differences in observed characteristics whilst a pro-rural advantage emerges in 2014 dominated by the differences in coefficients. Health system development and campaign efforts have focused on rural areas. There is a need to also specifically target vulnerable children in urban areas, to maintain focus on women empowerment and pay attention to children from high socio-economic households in less favourable economic times. © 2018, The Author(s).

Inequalities in child mortality in ten major African cities

Background: The existence of socio-economic inequalities in child mortality is well documented. African cities grow faster than cities in most other regions of the world; and inequalities in African cities are thought to be particularly large. Revealing health-related inequalities is essential in order for governments to be able to act against them. This study aimed to systematically compare inequalities in child mortality across 10 major African cities (Cairo, Lagos, Kinshasa, Luanda, Abidjan, Dar es Salaam, Nairobi, Dakar, Addis Ababa, Accra), and to investigate trends in such inequalities over time.Methods: Data from two rounds of demographic and health surveys (DHS) were used for this study (if available): one from around the year 2000 and one from between 2007 and 2011. Child mortality rates within cities were calculated by population wealth quintiles. Inequality in child mortality was assessed by computing two measures of relative inequality (the rate ratio and the concentration index) and two measures of absolute inequality (the difference and the Erreyger's index).Results: Mean child mortality rates ranged from about 39 deaths per 1,000 live births in Cairo (2008) to about 107 deaths per 1,000 live births in Dar es Salaam (2010). Significant inequalities were found in Kinshasa, Luanda, Abidjan, and Addis Ababa in the most recent survey. The difference between the poorest quintile and the richest quintile was as much as 108 deaths per 1,000 live births (95% confidence interval 55 to 166) in Abidjan in 2011-2012. When comparing inequalities across cities or over time, confidence intervals of all measures almost always overlap. Nevertheless, inequalities appear to have increased in Abidjan, while they appear to have decreased in Cairo, Lagos, Dar es Salaam, Nairobi and Dakar.Conclusions: Considerable inequalities exist in almost all cities but the level of inequalities and their development over time appear to differ across cities. This implies that inequalities are amenable to policy interventions and that it is worth investigating why inequalities are higher in one city than in another. However, larger samples are needed in order to improve the certainty of our results. Currently available data samples from DHS are too small to reliably quantify the level of inequalities within cities. © 2014 Quentin et al.; licensee BioMed Central Ltd.

Inequalities in early marriage, childbearing and sexual debut among adolescents in sub-Saharan Africa

Background: Adolescent sexual and reproductive health (ASRH) is a major public health concern in sub-Saharan Africa (SSA). However, inequalities in ASRH have received less attention than many other public health priority areas, in part due to limited data. In this study, we examine inequalities in key ASRH indicators. Methods: We analyzed national household surveys from 37 countries in SSA, conducted during 1990–2018, to exam ine trends and inequalities in adolescent behaviors related to early marriage, childbearing and sexual debut among adolescents using data from respondents 15–24 years. Survival analyses were conducted on each survey to obtain estimates for the ASRH indicators. Multilevel linear regression modelling was used to obtain estimates for 2000 and 2015 in four subregions of SSA for all indicators, disaggregated by sex, age, household wealth, urban–rural residence and educational status (primary or less versus secondary or higher education). Results: In 2015, 28% of adolescent girls in SSA were married before age 18, declined at an average annual rate of 1.5% during 2000–2015, while 47% of girls gave birth before age 20, declining at 0.6% per year. Child marriage was rare for boys (2.5%). About 54% and 43% of girls and boys, respectively, had their sexual debut before 18. The declines were greater for the indicators of early adolescence (10–14 years). Large diferences in marriage and childbearing were observed between adolescent girls from rural versus urban areas and the poorest versus richest households, with much greater inequalities observed in West and Central Africa where the prevalence was highest. The urban– rural and wealth-related inequalities remained stagnant or widened during 2000–2015, as the decline was relatively slower among rural and the poorest compared to urban and the richest girls. The prevalence of the ASRH indicators did not decline or increase in either education categories. Conclusion: Early marriage, childbearing and sexual debut declined in SSA but the 2015 levels were still high, especially in Central and West Africa, and inequalities persisted or became larger. In particular, rural, less educated and poorest adolescent girls continued to face higher ASRH risks and vulnerabilities. Greater attention to disparities in ASRH is needed for better targeting of interventions and monitoring of progress.

Inernational Non-Governmental Organizations (INGOS) and the Promotion of Children's Right to Quality Education in Ghana: A Case Study of World Vision International, Ghana.

This study focuses essentially on analyzing the extent of collaboration between World-Vision Ghana, the Government of Ghana and schools in ensuring the provision of quality education, as a way of promoting development across the country, with special reference to the Ga-West, Fanteakwa, and Afram Plains Districts. The study is purely qualitative and relies primarily on literature review and interviews for data collection and analyses. The main objective of the study was to assess the role of World Vision educational projects on children in rural communities who are not privileged to receive government support which leads to low literacy and learning in these communities. Major findings from the study reveals that World Vision-Ghana has adopted initiatives cooperation with the government and other relevant stakeholders garnered at ensuring the provision of education in Ghana, with special emphasis on the study area. Paramount among the initiatives are awareness creation, lobbying for effective legislation and policies, assisting in capacity, among others. The study also shows that the impacts such initiatives have had on education in the study area include improvement in grassroot participation in education delivery, improvement in general child literacy across the country, ensure equitable access to good quality, child-friendly free universal basic education, enhancement of teaching skills, and helping in the attainment of the goals and objectives of FCUBE. The study also reveals that the government, in cooperation with World Vision-Ghana have encountered a number of challenges in their quest to ensure the provision and improvement in child education in Ghana. These challenges coupled with economic hardships, lack of political will on the part of the government, among others. Towards this end, the study recommends that the Government of Ghana should continue to collaborate effectively with INGOs such as World Vision, to be able to effectively tackle the educational challenges especially in the provision of child education in Ghana.

Infammatory cytokines as potential biomarkers for early diagnosis of severe malaria in children in Ghana

Background Severe malaria (SM) is a fatal multi-system disease which accounted for an estimated 619,000 deaths in 2021. Less than 30% of children presenting with SM are diagnosed and treated promptly, resulting in increased mortality and neurologic impairments in survivors. Studies have identifed cytokine profles that diferentiate the vari‑ ous clinical manifestations of malaria (severe and uncomplicated). However, the diagnostic capability of these cytokines in diferentiating between the disease states in terms of cut-of values has not yet been determined. Methods The plasma levels of 22 pro-infammatory cytokines (Eotaxin/CCL 11, interferon-gamma (IFN-γ), interleukin (IL)- 2, IL-6, IL-1β, IL-12p40/p70, IL-17A, RANTES, MCP-1, IL-15, IL-5, IL-1RA, IL-2R, IFN-α, IP-10, TNF, MIG, MIP-1α, MIP-1β, IL-7, IL-8 and Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF), and 3 anti-infammatory cytokines (IL-4, IL-13 and IL-10) in patients with SM, uncomplicated malaria (UM) and other febrile conditions, were measured and compared using the Human Cytokine Magnetic 25-Plex Panel. The receiver operating characteristic (ROC) curve analysis was used to determine the diagnostic value of these cytokines. Results The level of the pro-infammatory cytokine, IL-17A, was signifcantly higher in the SM group as compared to the UM group. Levels of the anti-infammatory cytokines however did not difer signifcantly among the SM and UM groups. Only IL-1β and IL-17A showed good diagnostic potential after ROC curve analysis. Conclusion The data show that levels of pro-infammatory cytokines correlate with malaria disease severity. IL-1β and IL-17A showed good diagnostic potentials and can be considered for use in clinical practice to target treatment.

Infant and child health: Evidence from 2003 Ghana demographic and health survey

Review books or articles provide a critical and constructive analysis of existing published literature in a field, through summary, analysis, and comparison, often identifying specific gaps or problems and providing recommendations for future research. These are considered as secondary literature since they generally do not present new data from the author's experimental work. Review articles can be of three types, broadly speaking: literature reviews, systematic reviews, and meta-analyses. It also the researcher to stay abreast of new literature in the field.

Infant and young child feeding practices are associated with childhood anaemia and stunting in sub-Saharan Africa

Background The co-occurrence of anaemia and stunting (CAS) presents acute development and morbidity challenges to children particularly in sub-Saharan Africa (SSA). Evidence on the effect of child feeding recommendations on CAS is scarce. Methods We used data from 22 recent Demographic and Health Surveys in SSA countries to examine the association between caregivers’ implementation of recommendations on infant and young child feeding and the CAS in their 6- to 23-mo-old children. Results Overall, in multiple logistic regression models, child feed index score, high wealth of household, increasing household size, household head with at least secondary school education, improved sanitation of household, an increase in caregiver’s age and caregiver’s with at least secondary education were associated with lower odds of CAS (i.e., AOR: 0.86; 95% CI; 0.84 – 0.88: 0.75; 0.69 – 0.82: 0.98, 0.98 – 0.99: 0.76, 0.70 – 0.83: 0.81, 0.74 – 0.87: 0.87, 0.81 – 0.94: 0.69, 0.62 – 0.77 respectively). Having a diarrhoea in the past 2 weeks and having fever in the past month were associated with higher odds of CAS (AOR:1.1, 95% CI; 1.0 – 1.2: 1.1, 1.0 – 1.2, respectively). Results from the decision tree analysis showed that the educational level of women was the most important predictor of CAS, followed by child feeding score, the level of education of the family head and state of drinking water. Conclusion The results buttress the importance of interventions aimed at improving feeding practices and parental educational as a vehicle to improve children’s nutritional status.
