ABSTRACTIn this issue ofClinical and Vaccine Immunology, Siev and colleagues present an evaluation of antibody responses to four immunodominant proteins ofMycobacterium tuberculosisin patients with HIV-associated pulmonary tuberculosis (TB) in South Africa (M. Siev, D. Wilson, S. Kainth, V. O. Kasprowicz, C. M. Feintuch, E. Jenny-Avital, and J. J. Achkar, 21:791–798, 2014, doi:http://dx.doi.org/10.1128/CVI.00805-13). This commentary discusses the enormous need for simple point-of-care assays for tuberculosis (TB) diagnosis in patients with and without HIV coinfection in high-burden settings and considers the potential role of serological assays and the huge challenges inherent in developing and validating such assays.

Purpose – The purpose of this paper is to expand knowledge about how middle class consumers in Sub-Saharan African markets behave, focusing on the potential role of social networks and the subsequent interactions that take place between these consumers and firms. Design/methodology/approach – A qualitative research method approach comprising personal interviews and observations targeted at consumers and business executives was used covering all four countries. Findings – Key findings include identification of middle of the pyramid (MOP) social networks, their impact on consumer behaviour and nature of consumer and firm interactions that take place as a result of the impact of social networks. Research limitations/implications – The sample size was restricted to 80 consumers in each of the four countries. This might limit generalisability. Practical implications – The study provides managers with insights on the potential role of social networks on marketing to the MOP in Africa. Social implications – The study provides managers with insights on the potential opportunities for corporate social responsibility solutions at the MOP. Originality/value – Research into the middle class in markets other than western advanced economies is a relatively new area of study. The majority of studies on the middle class have focused on North America and Europe ignoring the merging middle class in Africa. Hence, this research expands knowledge by providing basis for exploring new insights on the emerging marketing opportunity within the middle class in Africa.

Purpose The study seeks to examine the role of financial development (FD) in the Feldstein–Horioka (FH) puzzle. The novelty of this study is based on the fact that the measures of FD are expanded to account for the qualitative nature of the financial sector (“better finance”). Design/methodology/approach The study used annual dataset for 37 countries in sub-Saharan Africa (SSA) for the period 1999 through 2010 and relied on the system generalised method of moments (GMM) technique, which takes accounts of endogeneity-related issues. Findings The estimated FH coefficients ranged between 0.419 and 0.720. The qualitative measures of FD have higher FH coefficient relative to the traditional or quantitative measure of FD (“more finance”). Hence, improvement in both the quantity and quality of the financial sector might be helpful in the mobilization, distribution and utilization of savings for investment purposes within these economies. The high FH coefficients obtained suggest that the FH puzzle does not hold in the SSA region. Practical implications Policymakers should formulate and design policies that would seek to ensure the development of the financial sector both in terms of quantity and quality. While taking this into consideration, special attention should be devoted to the qualitative measure of finance. Originality/value The study extends the work of Adeniyi and Egwaikhide (2013) by providing different and, possibly better proxies for FD to capture the efficiency and the qualitative nature of the financial system. This crux of the study serves as the value addition to the literature, as no other study the authors are aware of, has considered the importance of “better finance” indicators in the saving – investment nexus investigation.

PurposeGlobally, women have been recognized as key contributors toward livelihood and poverty eradication, especially in developing countries in sub-Saharan Africa. This is due to their great involvement and participation in micro small and medium enterprises (MSMEs) that create employment and ultimately economic growth and development. Thus, the main purpose of this study is to establish the mediating role of social cohesion in the relationship between microfinance accessibility and survival of women MSMEs in post-war communities in sub-Saharan Africa, especially in Northern Uganda where physical collateral were destroyed by war.Design/methodology/approachThe data for this study were collected using a pre-tested semi-structured questionnaire from 395 women MSMEs who are clients of microfinance institutions in post-war communities in Northern Uganda, which suffered from the 20 years' Lord Resistance Army (LRA) insurgency. The Analysis of Moment Structures (AMOS) software was used to analyze the data and the measurement and structural equation models were constructed to test for the mediating role of social cohesion in the relationship between microfinance accessibility and survival of women MSMEs in post-war communities.FindingsThe results revealed that social cohesion significantly and positively mediate the relationship between microfinance accessibility and survival of women MSMEs in post-war communities in Northern Uganda. The results suggest that the presence of social cohesion as a social collateral promotes microfinance accessibility by 14.6% to boost survival of women MSMEs in post-war communities where physical collateral were destroyed by war amidst lack of property rights among women. Similarly, the results indicated that social cohesion has a significant influence on survival of women MSMEs in post-war communities in Northern Uganda. Moreover, when combined together, the effect of microfinance accessibility and social cohesion exhibit greater contribution towards survival of women MSMEs in post-war communities in Northern Uganda. Indeed, social cohesion provides the social safety net (social protection) through which women can access business loans from microfinance institutions for survival and growth of their businesses.Research limitations/implicationsThis study concentrated mainly on women MSMEs located in post-war communities in developing countries in sub-Saharan Africa with a specific focus on Northern Uganda. Women MSMEs located in other regions in Uganda were not sampled in this study. Besides, the study focused only on the microfinance industry as a major source of business finance. It ignored the other financial institutions like commercial banks that equally provide access to financial services to micro-entrepreneurs.Practical implicationsThe governments in developing countries, especially in sub-Saharan Africa where there have been wars should waive-off the registration and licensing fees for grass-root associations because such social associations may act as social protection tools through which women can borrow from financial institutions like the microfinance institutions. The social groups can provide social collateral to women to replace physical collateral required by microfinance institutions in lending. Similarly, the governments, development agencies, and advocates of post-war reconstruction programs in developing countries where there have been wars, especially in sub-Saharan Africa should initiate the provision of group business loans through the existing social women associations. This may offer social protection in terms of social collateral in the absence of physical collateral required by the microfinance institutions in lending. This may be achieved through partnership with the existing microfinance institutions operating in rural areas in post-war communities in developing countries. Additionally, advocates of post-war recovery programs should work with the existing microfinance institutions to design financial products that suit the economic conditions and situations of the women MSMEs in post-war communities. The financial products should meet the business needs of the women MSMEs taking into consideration their ability to fulfil the terms and conditions of use.Originality/valueThis study revisits the role of microfinance accessibility in stimulating survival of women MSMEs as an engine for economic growth in the presence of social cohesion, especially in post-war communities in sub-Saharan Africa where physical collateral were destroyed by war. It reveals the significant role of social cohesion as a social protection tool and safety net, which contributes to economic outcomes in the absence of physical collateral and property rights among women MSMEs borrowers, especially in post-war communities.

Abstract In the context of the nutrition transition, women in sub-Sahara Africa are a critical target group from a nutrition standpoint, and they experience significant discrimination in food production. Food-based, women-centered strategies are recommended to address nutrient gaps, and to educate and empower women. In this context, local natural resources, such as neglected and underutilized plant species (NUS), may contribute to adding nutritional value, enriching diet diversity, and ensuring nutrition security. The aim of the current narrative review is to investigate the nutritional status of the sub-Saharan African population and the potential role of local agriculture strategies in improving food production and diet diversity and in expanding income-generating activities for women. The nutritional properties of the most important regional NUS are also discussed.

PurposeThis study investigates the role of financial access in moderating the effect of governance on insurance consumption in 42 sub-Saharan African countries using data for the period 2004–2014.Design/methodology/approachTwo life insurance indicators are used, notably: life insurance and non-life insurance. Six governance measurements are also used, namely: political stability, ‘voice and accountability’, government effectiveness, regulation quality, corruption-control and the rule of law. The empirical evidence is based on the Generalised Method of Moments (GMM) and Least Squares Dummy Variable Corrected (LSDVC) estimators.FindingsEstimations from the LSDVC are not significant while the following main findings are established from the GMM. First, financial access promotes life insurance through channels of political stability, ‘voice and accountability’, government effectiveness, the rule of law and corruption-control. Second, financial access also stimulates non-life insurance via governance mechanisms of political stability, ‘voice and accountability’, government effectiveness, regulation quality, the rule of law and corruption-control.Originality/valueThis research complements the sparse literature on insurance promotion in Africa by engaging the hitherto unexplored role of financial access through governance channels.
