Purpose This study aims to investigate the role of information and communication technology (ICT) in modulating the effect of governance on insurance penetration in 42 Sub-Saharan African countries using data for the period 2004-2014. Design/methodology/approach Two insurance indicators are used in the analysis, namely, life insurance and non-life insurance. The three ICT modulating dynamics used include mobile phone penetration, internet penetration and fixed broadband subscriptions. Six governance channels are also considered, namely, political stability, “voice & accountability”, regulation quality, government effectiveness, the rule of law and corruption-control. The empirical evidence is based on generalized method of moments. Findings The following main findings are established. First, mobile phone penetration does not significantly modulate governance channels to positively affect life insurance while it effectively complements “voice & accountability” to induce a positive net effect on non-life insurance. Second, internet penetration complements governance dynamics of political stability, government effectiveness and rule of law to induce positive net effects on life insurance and corruption-control for an overall positive effect on non-life insurance. Third, the relevance of fixed broadband subscriptions in promoting life insurance is apparent via governance channels of regulation quality, government effectiveness and the rule of law while fixed broadband subscriptions do not induce significant overall net effects on non-life insurance though the conditional effects are overwhelmingly significant. Originality/value To the best of the authors’ knowledge, studies on the relevance of ICT in promoting insurance consumption through governance channels are sparse, especially for a region such as Sub-Saharan Africa where insurance penetration is low compared to other regions of the world.

Prior information systems (IS) research has provided valuable insight on technology adoption and use which is critical in deriving the benefits of information technology. These studies have utilized theories such as Technology Acceptance Model, Theory of Reason Action, and Technological determinism model to investigate technology adoption. This study continues in this line of research by evaluating the perspectives of investigating the concept of e-democracy within the framework of the Planned Behavioral Theory an extension to the Theory of Reason Action. The article seeks to explain internet and mobile enhanced citizen’s participation in democracy (e-democracy) base on their inherent (attitude) and environmental (subjective norms and perceived behavioral control) enablers and barriers to participate in e-democracy, and how the internet and wireless technologies can help to address democratic issues in resource poor settings such as the Sub Saharan Africa (SSA). The study takes the perspective of critical realism and thus provides an example of the application of this research paradigm in an empirical study. We investigated this phenomenon by providing a theoretical grounded model that explains e-democracy adoption adapted from the theory of Planned Behavior (TPB) and tested from an empirical examination of constructs using data from randomly selected sub-Saharan African countries. The results render support for the proposed hypotheses, emphasizing the role of human behavior on citizens’ e-democracy adoption.

Abstract Reducing postharvest losses (PHLs) of food crops is a critical component of sustainably increasing agricultural productivity. Many PHL reduction interventions have been tested, but synthesized information to support evidence-based investments and policy is scarce. In this study, PHL reduction interventions for 22 crops across 57 countries in sub-Saharan Africa and South Asia from the 1970s to 2019 were systematically reviewed. Screening of the 12,907 studies identified resulted in a collection of 334 studies, which were used to synthesize the evidence and construct an online open-access database, searchable by crop, country, postharvest activity and intervention type. Storage technology interventions mainly targeting farmers dominated (83% of the studies). Maize was the most studied crop (25%). India had the most studies (32%), while 25 countries had no studies. This analysis indicates an urgent need for a systematic assessment of interventions across the entire value chain over multiple seasons and sites, targeting stakeholders beyond farmers. The lack of studies on training, finance, infrastructure, policy and market interventions highlights the need for interventions beyond technologies or handling practice changes. Additionally, more studies are needed connecting the impact of PHL reductions to social, economic and environmental outcomes related to Sustainable Development Goals. This analysis provides decision makers with data for informed policy formulation and prioritization of investments in PHL reduction.

Purpose – The purpose of this study was to, using a case study research design informed by organizational economics theory, to examine the prospects for micro-insurance in promoting micro-credit in a low-income Anglophone country in sub-Saharan Africa – The Gambia. Two main research questions are addressed: first, what is the most appropriate micro-finance institution (MFI) organizational structure to maximize the economic benefits of micro-insurance? Second, what are the financial management and wider economic benefits of the use of micro-insurance by MFIs? Design/methodology/approach – To address our two research questions, we used a semi-structured interview protocol, informed by the organizational economics literature, to interpret the data collected from our field cases. We believe that these intrinsic qualities of case study methodology are particularly apt in the present study, given the complex and emergent nature of micro-finance and micro-insurance in low-income countries such The Gambia. By focusing on case studies in a single country, we also to some extent help control for variations in business environment that could confound interpretations of field data obtained from different jurisdictions. Findings – The results of our study suggest that the mutual (cooperative) structure of credit unions is likely to be the most cost-efficient and effective organizational form for reducing information asymmetries, agency problems and transaction costs. We also observe that micro-insurance can help reduce the risk of loan defaults, thereby increasing returns on savings and lowering the costs of debt. As such, micro-insurance stimulates the demand–supply of financial intermediation in less developed countries and so helps promote economic development. In addition to contributing new insights, our findings have potentially important commercial and public policy implications. Research limitations/implications – We acknowledge that our research is subject to inherent limitations such as the focus on three interviews in three different types of MFI organization while excluding other structural forms of organization such as government-owned/sponsored organizations. Nonetheless, the organizational characteristics of the cases examined in the present study are representative of most MFIs in developing countries. Given the prevalent hierarchical nature of corporate systems in sub-Saharan Africa, the views of the interviewees are also deemed to reflect those of other board members. Nonetheless, we acknowledge that the conclusions from our research may need to be tempered in line with these inherent limitations with the research approach adopted. Practical implications – The insights obtained from our Gambia-based research could be generalized to developing countries elsewhere in sub-Saharan Africa, and indeed, other parts of the developing world. Consequently, the study could be of interest and relevance to international financiers (e.g. the World Bank), aid agencies, governments and other development organizations. Originality/value – Despite its evident business and development potential, academic management research on micro-insurance, and in particular, its role in supporting micro-finance initiatives, is still very much at an embryonic stage. Our study thus seeks to fill this knowledge gap.

Purpose The technology determinism theory facilitated in assessing the impact of interactive radio and social network sites (SNSs) on development factors such as education, agriculture, health, and governance, by conducting an integrative and comprehensive literature review focusing on African countries. This paper aims to conduct this literature review to provide comprehensive empirical evidence on the impact of interactive radio and SNSs on development in Africa. Design/methodology/approach This study examined articles that were retrieved from online databases including EBSCOhost, Elsevier, Science Direct, SAGE Journals, Springer and Wiley Online Library. The keywords used included interactive radio, radio, development in Africa, SNS, agriculture, education, health, peace and governance. Search phrases were formulated using boolean operators “AND” and “OR.” Findings Study results revealed that interactive radio and SNSs improve knowledge among farmers and allow the dissemination of information on innovative agricultural techniques, which supports the adoption of sustainable practices. Interactive radio promotes political accountability because the strategies provide the voiceless and powerless communities with a platform to express themselves. This paper discovers that the incorporation of SNS with existing multimedia communication facilitates the dissemination of health-related information on illnesses such as Ebola, HIV, hypertension, diabetes and Polio, and interactive radio and SNS promote education among marginalized communities and under-served rural schools. Research limitations/implications The findings on the impact of interactive radio and SNSs do not represent all 54 countries in Africa. Although the studies included in this literature review were conducted in several countries such as South Africa, Nigeria, Somalia, Kenya, Malawi, Ghana, Tanzania, Uganda and Zambia, this limited the generalizability of the findings and recommendations. Also, the other potential limitation is that using the inclusion-exclusion criteria could have resulted in bias when selecting the studies to include in the review. Practical implications The paper might serve as a valuable source of information for students, academics and entrepreneurs where the impact of interactive radio and SNSs on agriculture, education, health and governance, which are core determinants of development in Africa, has been assessed for further case studies in this area. Social implications The use of interactive radio has helped in decreasing health issues caused by a deficiency in vitamin A among children in sub-Saharan Africa. Originality/value The development of sustainable and effective interactive radio programs is dependent on the collaboration of the core stakeholders such as governmental ministries, donor organizations and the mass communication sector. Numerous open sources on technology radio stations are available to employ social media managers to help in the application of knowledge.

At the beginning of the 21st century, the digital revolution has become global. Digitalization has overcome the boundaries of the field of information technology and began to provoke the metamorphosis of sociocultural reality. Gradually, society itself and, as a consequence, social sciences are changing. African studies, despite the fact that digital transformations in the region have been slow, is no exception. New plots and sources started to appear; new practices and methods began to develop and apply. This article is devoted to the evolution of the oral tradition of the Africans and representatives of the global African diaspora in terms of the “digital turn”. It emphasizes the importance of oral history as one of the main directions in the study of the history and culture of Africa, introduces and analyzes the terms of “orature” and “cyberture”. The author focuses on the transformation of the form and content of African narratives in the post-colonial era. The novelty of the research lies in the fact that it is the first time an African podcast is considered as an oral historical digital source. The article provides a brief overview of podcasts created by people from Sub-Saharan and Southern Africa in the 2010s, describes the prerequisites for creating these projects, their thematic field, and analyzes their features. Particular emphasis is placed on issues of representations and interpretations of the cultural and historical experience of Africans and members of the African diaspora. The main dilemmas of placing podcasts into the context of oral history are articulated at the end of the article. The author also concludes that African podcasts are in line with the metamodern discourse.

The International Energy Agency has projected that the total energy demand for electricity in sub-Saharan Africa (SSA) is expected to rise by an average of 4% per year up to 2040. It implies that ~620 million people are living without electricity in SSA. Going with the 2030 vision of the United Nations that electricity should be accessible to all, it is important that new technology and methods are provided. In comparison to other nations worldwide, smart grid (SG) is an emerging technology in SSA. SG is an information technology-enhanced power grid, which provides a two-way communication network between energy producers and customers. Also, it includes renewable energy, smart meters, and smart devices that help to manage energy demands and reduce energy generation costs. However, SG is facing inherent difficulties, such as energy theft, lack of trust, security, and privacy issues. Therefore, this paper proposes a blockchain-based decentralized energy system (BDES) to accelerate rural and urban electrification by improving service delivery while minimizing the cost of generation and addressing historical antipathy and cybersecurity risk within SSA. Additionally, energy insufficiency and fixed pricing schemes may raise concerns in SG, such as the imbalance of order. The paper also introduces a blockchain-based energy trading system, which includes price negotiation and incentive mechanisms to address the imbalance of order. Moreover, existing models for energy planning do not consider the effect of fill rate (FR) and service level (SL). A blockchain levelized cost of energy (BLCOE) is proposed as the least-cost solution that measures the impact of energy reliability on generation cost using FR and SL. Simulation results are presented to show the performance of the proposed model and the least-cost option varies with relative energy generation cost of centralized, decentralized and BDES infrastructure. Case studies of Burkina Faso, Cote d’Ivoire, Gambia, Liberia, Mali, and Senegal illustrate situations that are more suitable for BDES. For other SSA countries, BDES can cost-effectively service a large population and regions. Additionally, BLCOE reduces energy costs by approximately 95% for battery and 75% for the solar modules. The future BLCOE varies across SSA on an average of about 0.049 $/kWh as compared to 0.15 $/kWh of an existing system in the literature.

Purpose—This research discusses emerging trends in financial inclusion, barriers and factors influencing mobile banking as an innovative solution for increasing financial inclusion in sub-Saharan Africa (SSA) with a specific focus on Nigeria. Design/methodology/approach—Using a qualitative meta-synthesis (QMS), an interpretivist research paradigm, authors provide an analytical tool for understanding the subject of inquiry by integrating findings from previous studies and relevant data from the reports of the Central Bank of Nigeria on emerging trends in financial inclusion. Findings—Three major factors emerged as drivers of mobile banking in Nigeria: (a) the ease of using mobile devices for personal banking transactions including prompt information about users’ financial transactions (savings and withdrawals) immediately through SMS (short message service) alert (easy management of my account); (b) the security/safety concerns of theft and cyber fraud; (c) social influence of friends, relatives, policy makers and social trends. Implications—In contextualizing mobile banking in SSA and in Nigeria in particular, this paper contributes to exploring the growth in the use of mobile banking by linking it with the “value in use” (VIU) perspective. This approach of the service dominant logic involves three sub-constructs (experience, personalization, and relationship), which all validate and support the proposed assertion that mobile banking is adopted by users because of utility expectancy (perceived usefulness), effort expectancy (perceived ease of use), and social influence expectancy (opinions of friends/relatives). Originality/value—This research, although qualitative in nature, validates information technology (IT) adoption theories/perspectives and enriches the “value in use” approach.

Purpose Food safety in emerging and developing regions is receiving increased attention from economists, researchers and policymakers. The purpose of this paper is to provide a review of the literature on the economics of food safety in Asia and Sub-Saharan Africa (SSA). Of interest are studies exploring consumer demand and producer behavior regarding food safety. Particular attention is given to areas in need of additional research. The studies’ common implications for future research are discussed. Design/methodology/approach Two English language searches were conducted in the summer of 2013 to identify relevant studies on the economics of food safety, one each in Google Scholar and Web of Science. The authors carefully reviewed the abstracts of these studies for content, and select papers were identified that capture overarching themes found in the literature. Findings are presented by region. Findings Consumers in developing countries will become increasingly aware of food safety issues as urbanization proceeds and incomes continue to rise at robust rates. However, assuring food safety in modernizing food systems involves significant costs, and current incomes in developing SSA are far lower than in Asia. The authors find that overall consumer awareness of food safety problems in SSA is low relative to Asia. Moreover, knowledge of producer behavior and consumer demand for food safety in developing countries is very limited. Research limitations/implications Limitations include a lack of information available on domestic food safety issues and overall knowledge of how food safety affects developing agrifood systems. Originality/value The findings from this review contribute to a better understanding of the economics of food safety in emerging and developing regions.

Purpose The inception of mobile financial services (MFSs) has positively provoked economic growth and productivity, nonetheless, it has pessimistically caused an upward surge in cybersecurity threat. Customers are progressively becoming conscious of some of the threat and several of them now shun away from some suspicious activities over the internet as a form of protection. This study aims to explore the factors that influence users’ to adopt security behaviour. Design/methodology/approach A synthesis of theories – Self-efficacy and technology threat avoidance theories – was used to examine the security behaviour of users of MFSs. Data was gathered from 530 students in Ghana using convenience sampling technique. Data analysis was carried out using descriptive statistics, inferential statistics and structural equation model. Findings Outcome of the investigation indicate that both mastery experience and verbal persuasion have substantial effect on the avoidance motivation of MFSs users. It was, however, found that emotional state and vicarious experience of users do not influence their avoidance motivation. Also, it was established that avoidance motivation is a positive prognosticator of avoidance behaviour. Practical implications Understanding the security behaviour of MFS users will help the operators to outline strategies to sustain the successes achieved. Originality/value Studies on user security behaviour are rare, especially in sub Saharan Africa, thus, this study will contribute to extant literature by adding a new dimension of user security behaviour.

Purpose This paper aims to extend the extant knowledge on virtual teams by examining the challenges of virtual project teams in organisations in Nigeria. Design/methodology/approach Data were collected through semi-structured interviews. Totally, 20 interviews were recorded, transcribed and analysed. Validity and reliability were achieved by first assessing the plausibility in terms of already existing knowledge on some of the virtual project team issues identified by participants. Findings The findings from this study confirmed the growing relevance of virtual project teams in highly competitive global business environments. It emerged that some of the challenges identified in the study had some level of congruence with those previously identified from similar studies from other geographical locations. The findings also suggested that challenges in virtual project teams can be linked to the organisation, the project team and the virtual environment or even a combination of all. Practical implications The present study corroborates the position that managing virtual project teams requires additional efforts to attain their objectives through effective communications and the adoption of appropriate technology. Originality/value The originality of this study lies in its exploration of virtual project team challenges in a sub-Saharan Africa country (Nigeria). By identifying the challenges associated with virtual project teams, stakeholders will be better able to successfully establish and manage virtual project teams better.

In 2011, a collaborative project focused on climate and ecosystem change adaptation and resilience studies in Africa (CECAR-Africa) with Ghana as the focal country, was initiated. The goal was to combine climate change and ecosystem change research, and to use that combination as a basis for building an integrated resilience enhancement strategy as a potential model for semi-arid regions across Sub-Saharan Africa. The Project is being financially supported by the Science and Technology Research Partnership for Sustainable Development (SATREPS), a collaborative programme of the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). CECAR-Africa involves the following leading climate and ecosystems research organizations in Ghana and Japan: The University of Tokyo; Kyoto University; United Nations University Institute for the Advanced Study of Sustainability (UNU-IAS); University of Ghana; Ghana Meteorological Agency; University for Development Studies; and United Nations University Institute for Natural Resources in Africa (UNUINRA). CECAR-Africa has been operating fully since 2012, with a focus on three thematic areas, namely: Forecast and assessment of climate change impact on agro-ecosystems (Agro-ecosystem resilience); Risk assessment of extreme weather hazards and development of adaptive resource management methods (Engineering resilience); and Implementing capacity development programs for local communities and professionals (social institutions-technical capacity development) using the assessment results derived from work on the first two themes. This special issue presents major outcomes of the Project so far. The articles featured used various techniques and methods such as field surveys, questionnaires, focal group discussions, land use and cover change analysis, and climate downscaled modelling to investigate the impacts of climate and ecosystem changes on river flows and agriculture, and to assess the local capacity for coping with floods, droughts and disasters, and for enhancing the resilience of farming communities. We are happy to be able to publish this special issue just in time for an international conference on CECAR-Africa in Tamale, Ghana, on 6-7 August, 2014. It is hoped that the shared research outcomes will facilitate discussions on the project research themes and interactions and exchange of ideas among academics, professionals, and government officials on the way forward for the CECARAfrica Project. We find it only appropriate to conclude by thanking the authors and reviewers of the articles, and by acknowledging, with gratitude, the local knowledge and other bits and pieces of information contributed by the many anonymous farmers and other people of northern Ghana.

Purpose This paper aims to review scientific contributions that are essential to reduce the challenges to food security in Africa through food processing and appropriate storage technologies. Design/methodology/approach Several literature studies on the role of food processing and appropriate storage technologies in ensuring food security and food availability in Africa were critically reviewed. Findings The study revealed that the world faces multiple challenges to food security including under nutrition and overconsumption, rising food prices, population growth, rapid diet transitions, threats to agricultural production, inefficient production practices and supply chains and declining investment in food system research. Many people lack adequate amounts of foods that are rich in the nutrients needed for a healthy and productive life. According to FAO, 1996, chronic undernutrition affects 43 per cent of the Africa’s population or some 215 million people in sub-Saharan Africa. Food security is highly instrumental to the economic growth and sustainability of any country. The use of simple but effective on- and off-farm storage facilities and agro-processing technology should be promoted to add value to products and increase their shelf-life. The Strategic Grain Reserve Scheme should be modernized, strengthened and upgraded to a National Food Reserve Program, which will enable it to handle all staples and essential food products. This will help in attainment of national food security goal. It is also crucial to promote and develop agro-processing in the various African countries for the evolution of virile agro-allied industries and rural micro-enterprises. Research limitations/implications The paper reviewed the role of food processing and appropriate food storage technologies in ensuring food security and availability in Africa. There are insufficient data and information on adoption of new food processing and appropriate storage technologies in Africa. Although, there have been some instances where the introduction of modern techniques has resulted in products rejection by consumers. Practical implications The paper helps in reviewing food situation in Africa and how to make food available for the people and Africa food secured. Social implications This paper revealed strategies that could be used to improve food security and ensuring food availability in Africa. Originality/value This review paper is of value to policymakers, government agencies responsible for food quality control and assurance and consumers to make food available and affordable for the people.

Purpose The purpose of this paper is to consider recent field evidence to analyse what online public services citizens need, explores potential citizen subsidy of these specific services and investigates where resources should be invested in terms of media accessibility. The authors explore these from a citizen-centric affordability perspective within three exemplar developing countries in sub-Saharan Africa. The World Bank and United Nations in particular promote initiatives under the “Information and Communication Technologies for Development” (ICT4D) to stress the relevance of e-Government as a way to ensure development and reduce poverty. The authors adopt a contingency value approach to determine directly reported citizens willingness to pay for digital public services. Hence, our focus is mainly upon an empirical investigation through extensive fieldwork in the context of sub-Sahara Africa. A substantive survey was conducted in the respective cities of Addis Ababa (Ethiopia), Lagos (Nigeria) and Johannesburg (South Africa). The sample of citizens was drawn from each respective Chamber of Commerce database for Ethiopia and South Africa, and for Nigeria a purchased database of businesses, based on stratified random sampling. These were randomly identified from both sectors ensuring all locations were covered with a total sample size of 1,297 respondents. It was found, in particular, that citizens were willing to pay to be able to access digital public services and that amounts of fees they were willing to pay varied depending on what services they wish to access and what devices they use (PCs or mobile phones). Design/methodology/approach The authors adopt a contingency value approach to determine directly reported citizens willingness to pay for digital public services. A survey was conducted in the respective cities of Addis Ababa (Ethiopia), Lagos (Nigeria) and Johannesburg (South Africa). The sample of citizens was drawn from each respective Chamber of Commerce database for Ethiopia and South Africa, and for Nigeria a purchased database of businesses, based on stratified random sampling. These were randomly identified from both sectors ensuring all locations were covered with a total sample size of 1,297 respondents. Findings The findings suggest that by understanding citizen needs, demands and how they can benefit from online public services could drive decisions related to what public services need to be prioritised for economically active citizens, potentially explore citizen subsidy of these specific public services which will have a trickle-down benefit to poorer citizens by reducing the pressures on traditional channels of public service delivery and investigate where resources should be invested in terms of media to access online services. Willingness to pay between the top online public services showed no statistically significant difference among all respondents. Research limitations/implications The research focused on economically active digitally savvy citizens in the major capital cities in each of our selected countries. While these are not representative of the population at large, our intention was to understand what citizen-led government services would look like from the perspective of this group, with an insight into the value they place on these online services and their ability to access them. Technology diffusion starts with the early adopters (Rogers, 2010), and here the authors have focused on those that are likely to be early adopters. Practical implications Poor fiscal capacity, namely, the amount and type of resources a state has at its disposal, not only has an impact on economic wellbeing, but particularly relevant in this case, also has an impact on the quality of government (Baskaran and Bigsten, 2013). Thus, e-government is one way in which developing countries can focus on developing good governance and strengthening civil society to improve the quality of government and motivate citizens to participate in the political process. Social implications The economic performance of African countries has been viewed with pessimism, consistently considered to be the poorest continent (Harrison et al., 2014). Recent studies have empirically shown that new information technologies have contributed to longer term economic growth in African countries and stress the need for government to further invest in developing telecommunications infrastructures and internet access (Donou-Adonsou et al., 2016). However one of the major constraints and challenges for developing countries is the limited fiscal capacity and ability to mobilise fiscal resources to finance the provision of public services, which is essential for economic development (Ali et al., 2015). Originality/value The authors contribute to the World Bank and United Nations initiatives to promote ICT for Development’ (ICT4D) the relevance of e-government as a way to ensure development and reduce poverty. If online services are of no benefit, even if they are more convenient and lower cost, they are unlikely to be used. Accessing digital public services directly addresses the needs of economically active citizens and can also facilitate the steps towards an improved quality of government and interaction with civil society. The study has contributed to an insightful understanding of the value, cost and benefits of citizen-led e-Government in this respect.

Purpose Of breast cancer–related deaths worldwide, 62.1% occur in low- and middle-income countries (LMICs). Mammography, the gold standard for screening, is largely infeasible in limited-resource settings, predominantly because of unavailability. Recent data show a dismal 0 to 12 mammography units per one million women age 50 to 69 years in most of sub-Saharan Africa. Breast ultrasound, which is used in high-resource settings to supplement mammography in certain clinical scenarios, offers a potentially viable alternative for early breast cancer detection in resource-limited areas because it is portable, economical, and a versatile technology. Methods We conducted a review of the literature to assess the potential for ultrasound alone in the detection of breast cancer. PubMed and Scopus queries with terms “breast neoplasms” and “diagnostic imaging” were systematically filtered to n = 33. Inclusion criteria were peer-reviewed studies in human participants, retrospective or prospective reviews, and a reference standard of biopsy/histopathology. Each paper was required to have extractable data with which to calculate true positives, false positives, true negatives, and false negatives. Breast imagers reviewed each paper using QUADAS and reached consensus for inclusion. Results Heterogeneity analyses confirmed a high diversity of all included studies. Pooled weighted analyses of all included studies demonstrated that the sensitivity of ultrasound for the detection of breast cancer ranged from 17% to 100%, with a 69% mean. This is higher than the known reported sensitivity of mammography for breast cancer detection of 67.8%. The specificity of ultrasound ranged from 28% to 100%, with a pooled total specificity of 97%, which is higher than the known specificity of mammography of 75%. In addition, ultrasound performed with superior sensitivity to mammography in the studies performed in LMICs that directly compared ultrasound with mammography (six of 11 studies). In the remaining five studies in LMICs, the sensitivity of ultrasound for breast cancer detection was high and ranged from 62% to 100%. Stratified analyses by age, breast density, presenting symptoms, and high-risk factors maintained the high sensitivities and specificities of ultrasound. Conclusion Sensitivities and specificities of ultrasound are comparable to mammography for the detection of invasive breast cancer. Handheld ultrasound may offer a viable alternative where mammography is not widely available as a primary detection modality for breast cancer.

Purpose The purpose of this paper is to examine how linkages between information and communication technology (ICT) and remittances affect the doing of business. Design/methodology/approach The focus is on a panel of 49 Sub-Saharan African (SSA) countries for the period 2000–2012. The empirical evidence is based on the generalized method of moments. Findings While the authors establish some appealing results in terms of net negative effects on constraints to the doing of business (i.e. time to start a business and time to pay taxes), some positive net effects are also apparent (i.e. number of start-up procedures, time to build a warehouse and time to register a property). The authors also establish ICT penetration thresholds at which the unconditional effect of remittances can be changed from positive to negative, notably: for the number of start-up procedures, an internet level of 9.00 penetration per 100 people is required, while for the time to build a warehouse, a mobile phone penetration level of 32.33 penetration per 100 people is essential. Practical and theoretical implications are discussed. Originality/value To the best of the authors’ knowledge, this is the first study to assess linkages between ICT, remittances and doing business in SSA.

Purpose The purpose of this paper is to investigate factors affecting the adoption of agricultural technologies in Sub-Saharan Africa, specifically the role of credit market inefficiency in adoption of agricultural technologies in the region. Design/methodology/approach Most importantly, the paper applies a 2SLS model on a unique data set on nine agrarian countries from Sub-Saharan Africa’s intensification of food crops agriculture (Afrint) to provide evidence on how credit market inefficiency affects adoption of technologies in the sub region. Findings The study finds that the relationship between credit and technology adoption is one-way causal relation (i.e. credit access leads to technology adoption) as opposed to a two-way relation (i.e. mutual dependent relation). Further, the results indicate that credit market inefficiency can be a major barrier to the adoption of yield enhancing technologies in Sub-Saharan Africa. Further, the study showed mixed results for household variables. The results give credence to studies that highlight the importance of infrastructure and risk control in the adoption of new technologies. Research limitations/implications The study is limited to only nine countries in Sub-Saharan Africa. Thus, the findings and interpretations should be considered as such. Further, there is the need for further research that considers all the region so as to establish whether or not there is a relationship between credit market inefficiencies and technology adoption in the region. Practical implications The policy implication is that microfinance institutions should consider scaling up their credit services to ensure that more households benefit from it, and in so doing technology adoption will be enhanced. Originality/value The main contribution of the study lies in its use of a unique data set from Sub-Saharan Africa’s intensification of food crops agriculture (Afrint) to investigation relationship between credit market inefficiency and technology adoption.

PurposeThe purpose of this study is to examine the impact of economic freedom on four key health indicators (namely, life expectancy, infant mortality rate, under-five mortality rate and neonatal mortality rate) by using a panel dataset of 34 sub-Saharan African countries from 2005 to 2016.Design/methodology/approachThe study obtains data from the World Development Indicators (WDI) of the World Bank and the Fraser Institute. It uses fixed effects regression to estimate the effect of economic freedom on health outcomes and attempts to resolve the endogeneity problems by using two-stage least squares regression (2SLS).FindingsThe results indicate a favourable impact of economic freedom on health outcomes. That is, higher levels of economic freedom reduce mortality rates and increase life expectancy in sub-Saharan Africa. All areas of economic freedom, except government size, have a significant and positive effect on health outcomes.Research limitations/implicationsThis study analyses the effect of economic freedom on health at a broad level. Country-specific studies at a disaggregated level may provide additional information about the impact of economic freedom on health outcomes. Also, this study does not control for some important variables such as education, income inequality and foreign aid due to data constraints.Practical implicationsThe findings suggest that sub-Saharan African countries should focus on enhancing the quality of economic institutions to improve their health outcomes. This may include policy reforms that support a robust legal system, protect property rights, promote free trade and stabilise the macroeconomic environment. In addition, policies that raise urbanisation, increase immunisation and lower the incidence of HIV are likely to produce a substantial improvement in health outcomes.Originality/valueExtant economic freedom-health literature does not focus on endogeneity problems. This study uses instrumental variables regression to deal with endogeneity. Also, this is one of the first attempts to empirically investigate the relationship between economic freedom and health in the case of sub-Saharan Africa.

Relatively little is known about agricultural groundwater use and the agricultural groundwater economy of sub-Saharan Africa. However, available evidence suggests that the region's groundwater resources are substantial and greater in per capita terms than in some of the worlds' largest agricultural groundwater users including India and China. Nonetheless, calculations presented here also indicate that the direct contribution of groundwater to sub-Saharan Africa's agricultural economy is small, both in absolute and relative terms. Plausible explanations for low usage include physical geography, economics and economic policies, and politics. In addition to these real factors, incomplete information almost certainly contributes to an underestimation of agricultural groundwater use. Further, it is likely that “traditional” approaches to groundwater valuation inherently miss some of the key groundwater functions in the sub-Saharan African context, in particular as they relate to livestock production and rainfall variability. While this paper supplies a baseline of information in some respects, much additional research is needed to improve our basic understanding of sub-Saharan Africa's agricultural groundwater use and importance, not only to help researchers and policy makers appreciate the value of the region's groundwater resources but also to provide a meaningful knowledge base on which development plans can be built. That said, the ultimate point of applied research should be to understand both where additional development in sub-Saharan Africa is possible and, equally important, where and why it is not.

PurposeDoes the issuance of Eurobonds carry enough information about favourable domestic conditions to warrant more FDI inflows? In this study, the authors investigate how FDI is responding to the rising levels of Eurobonds in sub-Saharan African (SSA).Design/methodology/approachThe study uses the system GMM model to set up a panel with all 17 SSA countries with Eurobonds. The dataset was transformed into time series, and the VAR model and Granger causality were used to diffuse the doubt of a possible bi-causal relationship between Eurobonds and FDI. Additionally, the authors use the impulse response function to test the behaviour of FDI to a one-time shock to Eurobonds.FindingsThe study reports that Eurobond levels matter in explaining FDI receipts. Specifically, the authors report that the issuance of Eurobonds leads to a favourable increase in FDI inflows. The authors transform our data into time series and use the VAR model and Granger causality test to diffuse the doubt of a possible bi-causal relationship between Eurobonds and FDI. The authors’ findings from this exercise suggest that two lag levels of Eurobond are a good predictor of future FDI flows. More also, the authors use the impulse response function to test the behaviour of FDI to a one-time shock to Eurobonds and report that a one-unit standard deviation shock to Eurobonds will cause FDI to swell up over at least 8 years.Research limitations/implicationsThe study is limited in scope due to data availability. Future studies may consider using countries across the globe that have issued Eurobond to retest the current research objectives.Practical implicationsThe study establishes grounds to suggest that the issuance of Eurobonds carry enough information to foreign investors in deciding on the location of FDI.Originality/valueThe study is uniquely opening a new frontier to the discussion on how one international capital can be used to bait other foreign capital. It also discusses signalling theory at the macro level.

This paper examines the question of what makes choice empowering and critiques prevalent approaches to empowerment focused narrowly on agency as the ability of individuals to make their own free choices and act independently. The implications of a narrow focus on agency are illustrated with the examples of technology choice in agriculture, specifically choices involved in the adoption of improved plant varieties. This example elucidates the limits of individual agency and permits an analysis of how choices may be structured to be either empowering or disempowering, with examples from specific plant breeding cases. In view of the importance given to equitable choice of technology for closing the gender gap in agricultural productivity and sustainability, the paper explores what practical steps can be taken towards a balanced approach to empowerment. An approach to designing a new plant variety by constructing choice differently is illustrated, using information on gender relations. The paper derives lessons from the plant breeding cases to inform other kinds of interventions, so that work on how choices are defined is given as much importance for empowerment as creating the option to choose. Agents who exercise power over rules and resources can either reproduce the status quo or innovate; thus, a balanced approach to empowerment requires careful analysis of the elements of choice.

The article questions the appropriation of existing urban planning and management tools in Sub-Saharan Africa, through a multiple case study: the implementation of a land information system (or simplified cadastre) in three cities in Benin. An ethnographic exploration of the use of the tool is conducted. The first section presents the historical context of the design of land information systems, framed by the urban management paradigm, and unwarranted confidence in new technologies. The second section presents the theoretical framework and the methodology of the research, inspired by public policy analysis and development anthropology. The third section describes findings of the multiple case studies. A vicious circle is highlighted, made up of: lack of political support, obsolescence, and decline of cost-effectiveness. The fourth section discusses the results of the ethnographic inquiry. These are, essentially, the interpretation of the paradoxes, blockages, and conflicts in the implementation of the tool in light of social, political and economic dynamics that take place at the local level, although unexpected by the creators of the tool.

It is a great pleasure to introduce the second volume second issue of our journal into the global community yearning for high-quality, impactful papers. IPJAF continues to seek and provide readers throughout the world with technology supported peer-reviewed scholarly articles on a broad range of established and emergent areas of accounting, finance, business, economics, and social sciences. I am resolute to maintain the high-quality standard of research and publication which is anchored on the exemplary service and dedication of our editorial board, editorial review and the editorial office. This volume 2, issue 2 comprises five manuscripts dealing with financial accounting, taxation, and auditing. The first article entitled “Examining the independent audit committee, managerial ownership, independent board member and audit quality in listed banks” by Dr. Hisar Pangaribuana (Adventist University of Indonesia, Bandung, Indonesia), Dr. Jenny Sihombinga (Adventist University of Indonesia, Bandung, Indonesia), and Dr. Oluwatoyin Muse Johnson Popoola (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) examines the effects of the independent audit committee on the relationship between managerial ownership and independent board member on audit quality in the Indonesian listed banks. The unit of analysis is companies carrying on the banking business and listed on the Indonesian stock exchange (IDX) between the period of 2010 to 2015. This study is explanatory (i.e., causal predictive), and uses the second generation structural equation modelling statistical analysis tools, PLS-SEM and PROCESS Partial Least Square for hypotheses testing. The results show that the independent board member has a significant impact on the independent audit committee and the audit quality. The study reveals that managerial ownership does not influence audit quality. The adoption of the independent audit committee with a long tenure of years can be potentially risky and less creative. As a result, their oversight functions may be in jeopardy, impaired or reduced performances. The research findings reveal no significant indirect effects of the independent audit committee on the relationship between managerial ownership, independent board member and audit quality in the banks listed in IDX. Independent board members need to renew the appointment of the independent audit committee members to improve the quality of the oversight functions undertaken by the audit committee, and hence, enhance audit quality. The authors suggest further research on the ideal level of managerial ownership and number of an independent board member to produce a good audit quality in the Indonesian listed banks. The second article titled “Salaried taxpayers’ internal states and assessment performance under self-assessment system: a quasi-experimental evaluation” by Dr. Noraza Mat Udin (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) takes a look at the first reform that impacts taxpayers, that is, the implementation of self-assessment system (SAS) to replace the old assessment system in 2004. The perception is that SAS had entirely changed the taxpayers’ responsibilities from being assessed by the tax authority to a person who is responsible for assessing own income tax liability. Her study explores the public fora debates on whether taxpayers can perform their responsibilities that were previously handled by trained tax personnel in Malaysia. Her paper reports the findings of a quasi-experimental evaluation of salaried individual taxpayers’ in the early stage of SAS implementation. She argues that a lot needs to be done, notwithstanding SAS had been implemented for more than a decade, the problem of taxpayer performance is continuing due to the dynamic nature of taxation in reality. The data were collected using a quasi-experimental method known as posttest-only no-treatment control group design. The sample comprised post-graduate students, who were actual taxpayers. Among the elements of the taxpayer’s internal states considered in this study, tax knowledge was found to have a significant relationship with assessment performance. Further analysis was conducted which showed that the majority of tax knowledge dimensions had a significant relationship with taxpayer assessment performance. The findings of this study have contributed to the body of knowledge because there is a general dearth of published research, particularly in Malaysia that investigates taxpayer assessment performance especially using an experimental approach. The third article with a caption, “Working capital management and firm performance: lessons learnt during and after the financial crisis of 2007-2008 in Nigeria” by Mr. Sunday Simon (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Dr. Norfaiezah Sawandi (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), and Prof. Dr. Mohamad Ali Abdul-Hamid (Department of Accounting, College of Business Administration, University of Sharjah, United Arab Emirate) examines the relationship between working capital management (WCM) and firm performance during and after the financial crisis of 2007-2008 in Nigeria. The authors argue that the financial crisis could be attributable to the deterioration and ultimate failure of WCM performance that affected many Nigerian firms. During the crisis, lending conditions were deeply affected, and financing operations became challenging for firms. Although research findings on the causes and effects of the crisis on the economy are known, what remains unknown is whether the financial crisis had a significant impact on WCM performance. The differences between the two periods, the crisis period and then after the crisis period, is operationalised through two analyses. The findings indicate that WCM variables have more explanatory power (R2) in the period after the crisis than during the crisis. Also, the results of the Cramer Z-statistic, which examined between sample comparisons of the R2, revealed that the Z-scores are significant, implying that a significant difference existed between the two periods. It suffices to say that WCM was affected during the financial crisis and led to low profitability, whereas, during the after-crisis period, WCM associates with higher profitability. These findings have implications for managers and policymakers because access to financing has become a global problem and adequate WCM management increases a company’s resilience to financial and external shocks. The fourth article entitled “The Influence of Technology Readiness on Information Technology Competencies and Civil Conflict Environment” by Prof. Dr. Kamil Md. Idris (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Associate Prof. Dr. Akilah Abdullah (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Haetham H. Kasem Alkhaffaf (OYA Graduate School of Business, College of Business, Universiti Utara Malaysia), and Al-Hasan Al-Aidaros (Islamic Business School, Universiti Utara Malaysia, Malaysia). Their study confirms prior findings that the Technology Readiness scale can capture the association among technology readiness and technology usage behaviours. The study also expands earlier research by investigating the impact of technology readiness on individual competency among accountants to using IT in a workplace under the intensity of civil conflict in Iraqi environment. The result shows that there is a positive significant relationship between technology readiness and the IT competencies of Iraqi accountants. It implies that the technology readiness regarding willingness, enthusiasm, and motivation of accountants using IT has an impact on their IT competencies. In other words, the higher the readiness of the accountants in making use of technology, the higher their competence in the use of IT. This study contributes to the body of knowledge in terms of theory, method and practice in Iraq especially and developing countries in general. The fifth article titled “Mediating effect of Quality-differentiated Auditor on the relationship between Managerial ownership and Monitoring mechanisms” and authored by Dr. Rachael Oluyemisi Arowolo (Chrisland University, Nigeria), Prof. Dr. Ayoib Che-Ahmad (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Dr. Oluwatoyin Muse Johnson Popoola (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) and Dr. Hisar Pangaribuana (Adventist University of Indonesia, Bandung, Indonesia) examines the relationship between Managerial Ownership (MO) and MMs with quality-differentiated auditors (QDA) as the channel for the relationship. Over the past decade, most studies in corporate governance and audit market emphasised the importance of monitoring mechanisms (MM), especially after the global economic meltdown resulting from the Enron saga. The literature on MM continues growing as many countries especially the Sub-Saharan Africa are still struggling to come out of the effect of the economic meltdown and businesses continues to fail or merge. The study used data from non-financial listed companies in Nigeria providing empirical supports that MO significantly associates with MMs in the right direction. Likewise, QDA also influences the MMs in the right direction suggesting that QDA is necessarily required to enhance adequate MMs. The findings of this study provide support for the association of MO and MMs with the intervention of QDA for solutions to agency problems. Companies should, therefore, motivate the management to own shares within the reasonable range that aligns the interest of the management with that of the shareholders. This paper adds to knowledge especially in Nigeria and Sub-Saharan Africa by examining a mediating effect to depict the relationship between MO and MM, which are not evident in prior studies It is my conviction that in the coming year, the vision of IPJAF to publish high-quality manuscripts in the established and emergent areas of accounting and finance from academic and professional researchers will be sustained and appreciated. As you read throughout this volume 2, issue 2 of IPJAF, I would like to remind you that the success of our journal depends on you, your friends and colleagues as stakeholder through the submission of high-quality articles for review and publication. Once again, I acknowledge with gratitude your continued support as we strive to make IPJAF the most authoritative journal on accounting and finance for the community of academic, professional, industry, society and government.

Purpose This paper aims to examine the long run impact of information and communication technology (ICT) on economic growth in the Sub Saharan African (SSA) region. The direct impact of ICTs use was examined for a 27-year period (1990-2014), before the Millennium Development Goals (MDGs) era (1990-1999) and during the MDGs era (2000-2014). Second and third objectives examined the nonlinear effect of ICT in the economic growth and their threshold values, respectively. The main growth enhancing transmission channels of ICT use were also looked at. Design/methodology/approach The study uses panel method technique of system generalist method of moment. The data period was collected from the years 1990-2014 from 45 SSA countries. The three main proxies of ICT are fixed telephone lines, mobile phone users and internet users per 100 inhabitants. Findings For the direct impact analysis, mobile phone and internet were found to have triggered economic growth. However, for nonlinear effect analysis, mass penetration of ICT proxies seems to slow economic growth. The threshold analysis showed a penetration rate threshold of 4.5 per cent for both mobile phone and internet, and 5 per cent for fixed telephone line before economic growth gets triggered. Finally, the results indicated that, except for financial development, human capital, institutional quality and domestic investment were the main growth enhancing transmission channels of ICTs use in the economy. Practical implications From a policy perspective, results suggest SSA region to open more doors for investment in technology to ensure sustainable development. Such policy has to focus on investment into main transmission channels of ICT, namely, human capital, institutional quality and domestic investment. The policymakers have to ensure that penetration of mobile phone, fixed telephone and internet is met by improvement in human capital, institutional quality and domestic investment. Moreover, to fully use the potential of ICT, improving the financial sector is highly recommended. Originality/value In SSA, studies that address the impact of ICT on economic growth was almost non-existent, especially on its nonlinear effect and main transmission channels. While few studies have examined the direct impact of ICT, this study extended the scope by including the main growth enhancing transmission channels and nonlinear effect of ICT on SSA economies using recent data.

Purpose The purpose of this paper is to empirically examine return and volatility spillovers between oil and the stock markets of Nigeria and South Africa. Design/methodology/approach The authors make use of an innovative new methodology of capturing spillovers, which is different from what many existing studies use. The authors employ the measures of return spillovers and volatility spillovers of Diebold and Yilmaz (2009, 2012), referred to as spillover indexes. The spillover index facilitates an assessment of the net contribution of one market in the information transmission mechanism of another market. Findings The empirical results show bi-directional, but weak interdependence between the South African and Nigerian stock markets returns and oil market returns. The results for volatility spillovers show independence of volatilities between Nigeria stock markets and oil markets, while weak bi-directional spillovers were found between South African equity volatilities and oil volatilities. The time-varying total spillover plots for returns and volatilities are broadly similar and show a trend that has been observed in other studies: an increasing trend during the non-crisis period, a burst in the crisis year, a maintained higher level of transmission afterwards. Originality/value Existing studies examining spillovers between oil and stock markets have largely ignored Sub-Saharan African markets. A common feature of existing studies is that they have been conducted for two groups of countries: either European and US markets; or Gulf Cooperation Council markets Thus, this study fills this gap in the literature by examining return and volatility spillovers between oil and the stock markets of Nigeria and South Africa.

BackgroundThe global health community and funding agencies are currently engaged in ensuring that worthwhile research-based programmes are sustainable. Despite its importance, few studies have analysed the sustainability of global health interventions. In this paper, we aim to explore barriers and facilitators for the wider implementation and sustainability of a mobile health (mHealth) intervention (Supporting LIFE Community Case Management programme) in Malawi, Africa.MethodsBetween January and March 2017, a qualitative approach was used to carry out and analyse 13 in-depth semi-structured interviews with key stakeholders across all levels of healthcare provision in Malawi to explore their perceptions with regards to the implementation and sustainability of the mHealth programme. Data were analysed thematically by two reviewers. ResultsOverall, our analysis found that the programme was successful in achieving its goals. However, there are many challenges to the wider implementation and sustainability of this programme, including the absence of monetary resources, limited visibility outside the healthcare sector, the lack of integration with community-based and nationwide programmes, services and information and communication technologies, and the limited local capacity in relation to the maintenance, further development, and management.ConclusionsFuture developments should be aligned with the strategic goals and interests of the Ministry of Health and engage with national and international stakeholders to develop shared goals and strategies for nationwide scale-up. These developments should also focus on building local capacity by educating trainers and ensuring that training methods and guidelines are appropriately accredited based on national policies. Our findings provide a framework for a variety of stakeholders who are engaged in sustaining mHealth programmes in resource-poor settings and can be used to develop an evidence-based policy for the utilization of technology for healthcare delivery across developing countries.

Over the past few decades, the wealth of Africa has not made African wealthy. There is a voicing that Africa is cursed, whether richly poor or poorly rich. Sub-Saharan Africa is commonplace for political turbulence, as well as humanitarian and economic misery. In such a catastrophic situa-tion, political economics studies have focused on the Resource Curses, Dutch Diseases, and Con-flict Resources in this area. A systematic scientometric analysis of this field would be beneficial but is currently lacking in the academic literature. Using VOSviewer and CiteSpace, this review fills the void by analyzing the 1783 articles published in the WoS SSCI Collection between 1993 and 2020 on the “Resource Curses”, “Dutch Diseases”, and “Conflict Resources”. The author dis-cusses recent papers with disruptive potential, references with the most robust citation explora-tions, and cooperation networks between authors and institutes. Three hotspots were detected: the causes and effects of the Resource curses; the interaction among the Resource Curses, Dutch Diseases, and Conflict Resources; the factors that affect rent collection and regime resilience. While the literature on the “Resource curse” and “Dutch Disease” has been around longer, studies on “Conflict Resources” are picking up quickly. Conflict Resources were characterized by active citation exploration keywords and multiple active co-citation clusters, including possibly groundbreaking articles. There is a massive overlap between the three strings of literature, but each one has its emphasis.

Purpose The purpose of this paper is to critically examine the impact of a growth enhancement support scheme (GESS) on youth development in informal farm entrepreneurship in Nigeria. Its special focus is to investigate the impact of the GESS on rural youths’ adoption of new technologies needed to sustainably increase food security in Nigeria. Design/methodology/approach This paper adopts a survey research technique, aimed at gathering information from a representative sample of the population, as it is essentially cross-sectional, describing and interpreting the current situation. A total of 800 rural youths were sampled across the six geopolitical zones of Nigeria. Findings The result from the use of a bivariate probit model indicates that the GESS has a significant impact on rural youths’ innovations in farming. Practical implications This suggests that information and communication technology could provide new opportunities for making farming more interesting and enterprising for rural young people. Social implications It implies that while old male and female farmers are less likely to adopt the new farming technologies needed to achieve Nigeria’s agricultural transformation agenda (ATA), a younger generation can help introduce new technologies, while also learning from traditional methods. Originality/value This research adds to the literature on informal farm entrepreneurship and rural communities’ debate in developing countries. It concludes that engaging youths in GESS should form the foundation of the ATA in Nigeria, which, in turn, would offer adequate combination of new and traditional solution to address the challenges of food insecurity in Sub-Saharan Africa.

Purpose This paper to examine the relationship between performance expectancy and behavioural intention to use mobile-based communication technologies for agricultural market information dissemination in Uganda. Design/methodology/approach A descriptive field survey method was adopted. A total of 302 commercial farmers and agribusiness traders in Eastern Uganda participated in the study from whom data were collected using self-administered questionnaires. Descriptive statistics, factor analysis, correlation and regression analyses were used in the study. Findings The findings reveal a significant positive relationship between performance expectancy and behavioural intentions to use mobile-based communication technologies for agricultural information access and dissemination. This implies that, commercial farmers’ behavioural intentions to use mobile-based communication technologies for agricultural market information dissemination and access will be influenced if they anticipate mobile-based communication technologies to offer greater performance in their daily transactions. Research limitations/implications This study was conducted in the context of resource constrained countries particularly in sub-Saharan Africa, however reflecting knowledge from other contexts. The study was conducted with a structured questionnaire being the main data collection tool, and this limited the study from collecting views outside the questions asked in the questionnaire. The variables studied could not be analysed for a long time, given that the study was cross-sectional in nature. Practical implications The study provides recommendations on how to further boost farmers’ behavioural intentions to use mobile-based communication technologies for agricultural information dissemination. Policy makers need to ensure that policies are put in place that encourage third party software developers and telecommunication companies to provide software products and solutions that are beneficial to the commercial farmers and can enable them complete their agricultural transactions in time. Social implications The study provides critical literature on the influence of performance expectancy on commercial farmers’ behavioural intentions to use mobile-based communication technologies for agricultural market information access and dissemination in resource constrained settings. Originality/value It is noted that farmers in Uganda are slowly progressing to newer mobile information and communication technology tools for market information access and dissemination; however, little is known as to why there is slow adoption of these mobile technologies for agricultural purposes; yet policy makers need to come up with proper strategies to encourage wide scale use of mobile technologies for agricultural market purposes.

Purpose Focusing on female entrepreneurs operating in a resource-scarce environment, this study aims to draw from the resource-based view to examine the relationship between entrepreneurial competences and firm growth. Design/methodology/approach This study used a cross-sectional research design. Data was collected from 232 women entrepreneurs operating in Kampala’s two biggest markets. The data were analyzed to test the mediation effect of absorptive capacity on the relationship between entrepreneurial competences and firm growth; a Sobel test and bootstrap estimation were analytical approaches that were used. Findings This paper argues that for female entrepreneurs, the venture growth process is not simply dependent on inimitable resources such as competences, as these are first not readily available to female entrepreneurs and second, only provide a temporary competitive advantage. Rather, venture growth also involves the ability to continuously identify and exploit knowledge resources through an absorptive capacity that may be limited by the sociocultural context within which the female entrepreneur operates in sub-Saharan Africa. Originality/value The novelty of this research resides in support for the mediating role of the ability to recognize the value of new information, assimilate it and apply it to commercial ends. This study shows that female entrepreneurs use externally generated knowledge as a mechanism to grow their firms and this is impacted by the sociocultural context within which they operate. The study further improves the understanding of the resource-based view by suggesting that a black box exists in the relationship between resources and performance. It is shown that the possession of one resource facilitates the acquisition of other resources and proposes that the role of resources continuously unfolds as a firm develops.

Considerable research has been conducted in the field of entrepreneurship. However, very few studies have explored the impact of entrepreneurship on the life satisfaction/happiness of individuals. Furthermore, they have yet to analyze the extent to which the impact of entrepreneurship is mediated by national cultures. The present study explores the effect of entrepreneurship on the life satisfaction/happiness of individuals and analyzes the extent to which such impact is mediated by ‘national cultures.’ Resorting to fixed effect panel data techniques, this study was conducted using the 2016 World Values Survey dataset, encompassing 90350 individuals from 60 countries over the 2010–2013 period, combined with information provided by the Global Leadership and Organizational Behavior Effectiveness (GLOBE) Framework on cultural measures. We found that being an entrepreneur increases the chances of happiness across the entire set of countries analyzed. Culture does matter in such relation as the impact of entrepreneurship on happiness varies across the sample, being positive for sub-Saharan Africa and Eastern Europe and negative for the Middle East culture cluster. Governments should implement active policies to foster the emergence of new businesses because new ventures enable countries not only to increase their output per capita, but also to achieve economic development by stimulating well-being and happiness. Nevertheless, this study highlights the danger of ‘blind’ recipes/formulas to promote entrepreneurship without considering the ‘entrepreneurship ecosystem’ and, at a more general level, the countries’ culture.

Global online platforms match firms with service providers around the world, in services ranging from software development to copywriting and graphic design. Unlike in traditional offshore outsourcing, service providers are predominantly one-person microproviders located in emerging-economy countries not necessarily associated with offshoring and often disadvantaged by negative country images. How do these microproviders survive and thrive? We theorize global platforms through transaction cost economics (TCE), arguing that they are a new technology-enabled offshoring institution that emerges in response to cross-border information asymmetries that hitherto prevented microproviders from participating in offshoring markets. To explain how platforms achieve this, we adapt signaling theory to a TCE-based model and test our hypotheses by analyzing 6 months of transaction records from a leading platform. To help interpret the results and generalize them beyond a single platform, we introduce supplementary data from 107 face-to-face interviews with microproviders in Southeast Asia and Sub-Saharan Africa. Individuals choose microprovidership when it provides a better return on their skills and labor than employment at a local (offshoring) firm. The platform acts as a signaling environment that allows microproviders to inform foreign clients of their quality, with platform-generated signals being the most informative signaling type. Platform signaling disproportionately benefits emerging-economy providers, allowing them to partly overcome the effects of negative country images and thus diminishing the importance of home country institutions. Global platforms in other factor and product markets likely promote cross-border microbusiness through similar mechanisms.

This paper aims to portray the overall picture of poverty in the world and mentions the key solution to overcome poverty from a critical perspective. The data and figures were quoted from a number of researchers and organizations in the field of poverty around the world. Simultaneously, the information strengthens the correlations among poverty and lack of education. Only appropriate philosophies of education can improve the country’s socio-economic conditions and contribute to effective solutions to worldwide poverty. In the 21st century, despite the rapid development of science and technology with a series of inventions brought into the world to make life more comfortable, human poverty remains a global problem, especially in developing countries. Poverty, according to Lister (2004), is reflected by the state of “low living standards and/or inability to participate fully in society because of lack of material resources” (p.7). The impact and serious consequences of poverty on multiple aspects of human life have been realized by different organizations and researchers from different contexts (Fraser, 2000; Lister, 2004; Lipman, 2004; Lister, 2008). This paper will indicate some of the concepts and research results on poverty. Figures and causes of poverty, and some solutions from education as a key breaker to poverty will also be discussed. Creating a universal definition of poverty is not simple (Nyasulu, 2010). There are conflicts among different groups of people defining poverty, based on different views and fields. Some writers, according to Nyasulu, tend to connect poverty with social problems, while others focus on political or other causes. However, the reality of poverty needs to be considered from different sides and ways; for that reason, the diversity of definitions assigned to poverty can help form the basis on which interventions are drawn (Ife and Tesoriero, 2006). For instance, in dealing with poverty issues, it is essential to intervene politically; economic intervention is very necessary to any definition of this matter. A political definition necessitates political interventions in dealing with poverty, and economic definitions inevitably lead to economic interventions. Similarly, Księżopolski (1999) uses several models to show the perspectives on poverty as marginal, motivation and socialist. These models look at poverty and solutions from different angles. Socialists, for example, emphasize the responsibilities of social organization. The state manages the micro levels and distributes the shares of national gross resources, at the same time fighting to maintain the narrow gap among classes. In his book, Księżopolski (1999) also emphasizes the changes and new values of charity funds or financial aid from churches or organizations recognized by the Poor Law. Speaking specifically, in the new stages poverty has been recognized differently, and support is also delivered in limited categories related to more specific and visible objectives, with the aim of helping the poor change their own status for sustainable improvement. Three ways of categorizing the poor and locating them in the appropriate places are (1) the powerless, (2) who is willing to work and (3) who is dodging work. Basically, poverty is determined not to belong to any specific cultures or politics; otherwise, it refers to the situation in which people’s earnings cannot support their minimum living standard (Rowntree, 1910). Human living standard is defined in Alfredsson & Eide’s work (1999) as follows: “Everyone has the right to a standard of living adequate for the health and well-being of himself and his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.” (p. 524). In addition, poverty is measured by Global Hunger Index (GHI), which is calculated by the International Food Policy Institute (IFPRI) every year. The GHI measures hunger not only globally, but also by country and region. To have the figures multi-dimensionally, the GHI is based on three indicators: 1. Undernourishment: the proportion of the undernourished as a percentage of the population (reflecting the share of the population with insufficient calorie intake). 2. Child underweight: the proportion of children under age 5 who are underweight (low weight for their age, reflecting wasting, stunted growth or both), which is one indicator of child under-nutrition. 3. Child mortality: the mortality rate of children under 5 (partially reflecting the fatal synergy of inadequate dietary intake and unhealthy environments). Apart from the individual aspects and the above measurement based on nutrition, which help partly imagine poverty, poverty is more complicated, not just being closely related to human physical life but badly affecting spiritual life. According to Jones and Novak (1999 cited in Lister, 2008), poverty not only characterizes the precarious financial situation but also makes people self-deprecating. Poverty turns itself into the roots of shame, guilt, humiliation and resistance. It leads the poor to the end of the road, and they will never call for help except in the worst situations. Education can help people escape poverty or make it worse. In fact, inequality in education has stolen opportunity for fighting poverty from people in many places around the world, in both developed and developing countries (Lipman, 2004). Lipman confirms: “Students need an education that instills a sense of hope and possibility that they can make a difference in their own family, school, and community and in the broader national and global community while it prepare them for multiple life choices.” (p.181) Bradshaw (2005) synthesizes five main causes of poverty: (1) individual deficiencies, (2) cultural belief systems that support subcultures of poverty, (3) economic, political and social distortions or discrimination, (4) geographical disparities and (5) cumulative and cyclical interdependencies. The researcher suggests the most appropriate solution corresponding with each cause. This reflects the diverse causes of poverty; otherwise, poverty easily happens because of social and political issues. From the literature review, it can be said that poverty comes from complex causes and reasons, and is not a problem of any single individual or country. Poverty has brought about serious consequences and needs to be dealt with by many methods and collective effort of many countries and organizations. This paper will focus on representing some alarming figures on poverty, problems of poverty and then the education as a key breaker to poverty. According to a statistics in 2012 on poverty from the United Nations Development Program (UNDP), nearly half the world's population lives below the poverty line, of which is less than $1.25 a day . In a statistics in 2015, of every 1,000 children, 93 do not live to age 5 , and about 448 million babies are stillborn each year . Poverty in the world is happening alarmingly. According to a World Bank study, the risk of poverty continues to increase on a global scale and, of the 2009 slowdown in economic growth, which led to higher prices for fuel and food, further pushed 53 million people into poverty in addition to almost 155 million in 2008. From 1990 to 2009, the average GHI in the world decreased by nearly one-fifth. Many countries had success in solving the problem of child nutrition; however, the mortality rate of children under 5 and the proportion of undernourished people are still high. From 2011 to 2013, the number of hungry people in the world was estimated at 842 million, down 17 percent compared with the period 1990 to 1992, according to a report released by the Food and Agriculture Organization of the United Nations (FAO) titled “The State of Food Insecurity in the World 2013” . Although poverty in some African countries had been improved in this stage, sub-Saharan Africa still maintained an area with high the highest percentage of hungry people in the world. The consequences and big problems resulting from poverty are terrible in the extreme. The following will illustrate the overall picture under the issues of health, unemployment, education and society and politics ➢ Health issues: According a report by Manos Unidas, a non- government organization (NGO) in Spain , poverty kills more than 30,000 children under age 5 worldwide every day, and 11 million children die each year because of poverty. Currently, 42 million people are living with HIV, 39 million of them in developing countries. The Manos Unidas report also shows that 15 million children globally have been orphaned because of AIDS. Scientists predict that by 2020 a number of African countries will have lost a quarter of their population to this disease. Simultaneously, chronic drought and lack of clean water have not only hindered economic development but also caused disastrous consequences of serious diseases across Africa. In fact, only 58 percent of Africans have access to clean water; as a result, the average life expectancy in Africa is the lowest in the world, just 45 years old (Bui, 2010). ➢ Unemployment issues: According to the United Nations, the youth unemployment rate in Africa is the highest in the world: 25.6 percent in the Middle East and North Africa. Unemployment with growth rates of 10 percent a year is one of the key issues causing poverty in African and negatively affecting programs and development plans. Total African debt amounts to $425 billion (Bui, 2010). In addition, joblessness caused by the global economic downturn pushed more than 140 million people in Asia into extreme poverty in 2009, the International Labor Organization (ILO) warned in a report titled The Fallout in Asia, prepared for the High-Level Regional Forum on Responding to the Economic Crisis in Asia and the Pacific, in Manila from Feb. 18 to 20, 2009 . Surprisingly, this situation also happens in developed countries. About 12.5 million people in the United Kingdom (accounting for 20 percent of the population) are living below the poverty line, and in 2005, 35 million people in the United States could not live without charity. At present, 620 million people in Asia are living on less than $1 per day; half of them are in India and China, two countries whose economies are considered to be growing. ➢ Education issues: Going to school is one of the basic needs of human beings, but poor people cannot achieve it. Globally, 130 million children do not attend school, 55 percent of them girls, and 82 million children have lost their childhoods by marrying too soon (Bui, 2010). Similarly, two-thirds of the 759 million illiterate people in total are women. Specifically, the illiteracy rate in Africa keeps increasing, accounting for about 40 percent of the African population at age 15 and over 50 percent of women at age 25. The number of illiterate people in the six countries with the highest number of illiterate people in the world - China, India, Indonesia, Brazil, Bangladesh and Egypt - reached 510 million, accounting for 70 percent of total global illiteracy. ➢ Social and political issues: Poverty leads to a number of social problems and instability in political systems of countries around the world. Actually, 246 million children are underage labors, including 72 million under age 10. Simultaneously, according to an estimate by the United Nations (UN), about 100 million children worldwide are living on the streets. For years, Africa has suffered a chronic refugee problem, with more than 7 million refugees currently and over 200 million people without homes because of a series of internal conflicts and civil wars. Poverty threatens stability and development; it also directly influences human development. Solving the problems caused by poverty takes a lot of time and resources, but afterward they can focus on developing their societies. Poverty has become a global issue with political significance of particular importance. It is a potential cause of political and social instability, even leading to violence and war not only within a country, but also in the whole world. Poverty and injustice together have raised fierce conflicts in international relations; if these conflicts are not satisfactorily resolved by peaceful means, war will inevitably break out. Obviously, poverty plus lack of understanding lead to disastrous consequences such as population growth, depletion of water resources, energy scarcity, pollution, food shortages and serious diseases (especially HIV/AIDS), which are not easy to control; simultaneously, poverty plus injustice will cause international crimes such as terrorism, drug and human trafficking, and money laundering. Among recognizable four issues above which reflected the serious consequences of poverty, the third ones, education, if being prioritized in intervention over other issues in the fighting against poverty is believed to bring more effectiveness in resolving the problems from the roots. In fact, human being with the possibility of being educated resulted from their distinctive linguistic ability makes them differential from other beings species on the earth (Barrow and Woods 2006, p.22). With education, human can be aware and more critical with their situations, they are aimed with abilities to deal with social problems as well as adversity for a better life; however, inequality in education has stolen opportunity for fighting poverty from unprivileged people (Lipman, 2004). An appropriate education can help increase chances for human to deal with all of the issues related to poverty; simultaneously it can narrow the unexpected side-effect of making poverty worse. A number of philosophies from ancient Greek to contemporary era focus on the aspect of education with their own epistemology, for example, idealism of Plato encouraged students to be truth seekers and pragmatism of Dewey enhanced the individual needs of students (Gutex, 1997). Education, more later on, especially critical pedagogy focuses on developing people independently and critically which is essential for poor people to have ability of being aware of what they are facing and then to have equivalent solutions for their problems. In other words, critical pedagogy helps people emancipate themselves and from that they can contribute to transform the situations or society they live in. In this sense, in his most influential work titled “Pedagogy of the Oppressed” (1972), Paulo Freire carried out his critical pedagogy by building up a community network of peasants- the marginalized and unprivileged party in his context, aiming at awakening their awareness about who they are and their roles in society at that time. To do so, he involved the peasants into a problem-posing education which was different from the traditional model of banking education with the technique of dialogue. Dialogue wasn’t just simply for people to learn about each other; but it was for figuring out the same voice; more importantly, for cooperation to build a social network for changing society. The peasants in such an educational community would be relieved from stressfulness and the feeling of being outsiders when all of them could discuss and exchange ideas with each other about the issues from their “praxis”. Praxis which was derived from what people act and linked to some values in their social lives, was defined by Freire as “reflection and action upon the world in order to transform it” (p.50). Critical pedagogy dialogical approach in Pedagogy of the Oppressed of Freire seems to be one of the helpful ways for solving poverty for its close connection to the nature of equality. It doesn’t require any highly intellectual teachers who lead the process; instead, everything happens naturally and the answers are identified by the emancipation of the learners themselves. It can be said that the effectiveness of this pedagogy for people to escape poverty comes from its direct impact on human critical consciousness; from that, learners would be fully aware of their current situations and self- figure out the appropriate solutions for their own. In addition, equality which was one of the essences making learners in critical pedagogy intellectually emancipate was reflected via the work titled “The Ignorant Schoolmaster” by Jacques Rancière (1991). In this work, the teacher and students seemed to be equal in terms of the knowledge. The explicator- teacher Joseph Jacotot employed the interrogative approach which was discovered to be universal because “he taught what he didn’t know”. Obviously, this teacher taught French to Flemish students while he couldn’t speak his students’ language. The ignorance which was not used in the literal sense but a metaphor showed that learners can absolutely realize their capacity for self-emancipation without the traditional teaching of transmission of knowledge from teachers. Regarding this, Rancière (1991, p.17) stated “that every common person might conceive his human dignity, take the measure of his intellectual capacity, and decide how to use it”. This education is so meaningful for poor people by being able to evoking their courageousness to develop themselves when they always try to stay away from the community due the fact that poverty is the roots of shame, guilt, humiliation and resistance (Novak, 1999). The contribution of critical pedagogy to solving poverty by changing the consciousness of people from their immanence is summarized by Freire’s argument in his “Pedagogy of Indignation” as follows: “It is certain that men and women can change the world for the better, can make it less unjust, but they can do so from starting point of concrete reality they “come upon” in their generation. They cannot do it on the basis of reveries, false dreams, or pure illusion”. (p.31) To sum up, education could be an extremely helpful way of solving poverty regarding the possibilities from the applications of studies in critical pedagogy for educational and social issues. Therefore, among the world issues, poverty could be possibly resolved in accordance with the indigenous people’s understanding of their praxis, their actions, cognitive transformation, and the solutions with emancipation in terms of the following keynotes: First, because the poor are powerless, they usually fall into the states of self-deprecation, shame, guilt and humiliation, as previously mentioned. In other words, they usually build a barrier between themselves and society, or they resist changing their status. Therefore, approaching them is not a simple matter; it requires much time and the contributions of psychologists and sociologists in learning about their aspirations, as well as evoking and nurturing the will and capacities of individuals, then providing people with chances to carry out their own potential for overcoming obstacles in life. Second, poverty happens easily in remote areas not endowed with favorable conditions for development. People there haven’t had a lot of access to modern civilization; nor do they earn a lot of money for a better life. Low literacy, together with the lack of healthy forms of entertainment and despair about life without exit, easily lead people into drug addiction, gambling and alcoholism. In other words, the vicious circle of poverty and powerlessness usually leads the poor to a dead end. Above all, they are lonely and need to be listened to, shared with and led to escape from their states. Community meetings for exchanging ideas, communicating and immediate intervening, along with appropriate forms of entertainment, should be held frequently to meet the expectations of the poor, direct them to appropriate jobs and, step by step, change their favorite habits of entertainment. Last but not least, poor people should be encouraged to participate in social forums where they can both raise their voices about their situations and make valuable suggestions for dealing with their poverty. Children from poor families should be completely exempted from school fees to encourage them to go to school, and curriculum should also focus on raising community awareness of poverty issues through extracurricular and volunteer activities, such as meeting and talking with the community, helping poor people with odd jobs, or simply spending time listening to them. Not a matter of any individual country, poverty has become a major problem, a threat to the survival, stability and development of the world and humanity. Globalization has become a bridge linking countries; for that reason, instability in any country can directly and deeply affect the stability of others. The international community has been joining hands to solve poverty; many anti-poverty organizations, including FAO (Food and Agriculture Organization), BecA (the Biosciences eastern and central Africa), UN-REDD (the United Nations Programme on Reducing Emissions from Deforestation and Forest Degradation), BRAC (Building Resources Across Communities), UNDP (United Nations Development Programme), WHO (World Health Organization) and Manos Unidas, operate both regionally and internationally, making some achievements by reducing the number of hungry people, estimated 842 million in the period 1990 to 1992, by 17 percent in 2011- to 2013 . The diverse methods used to deal with poverty have invested billions of dollars in education, health and healing. The Millennium Development Goals set by UNDP put forward eight solutions for addressing issues related to poverty holistically: 1) Eradicate extreme poverty and hunger. 2) Achieve universal primary education. 3) Promote gender equality and empower women. 4) Reduce child mortality. 5) Improve maternal health. 6) Combat HIV/AIDS, malaria and other diseases. 7) Ensure environmental sustainability. 8) Develop a global partnership for development. Although all of the mentioned solutions carried out directly by countries and organizations not only focus on the roots of poverty but break its circle, it is recognized that the solutions do not emphasize the role of the poor themselves which a critical pedagogy does. More than anyone, the poor should have a sense of their poverty so that they can become responsible for their own fate and actively fight poverty instead of waiting for help. It is not different from the cores of critical theory in solving educational and political issues that the poor should be aware and conscious about their situation and reflected context. It is required a critical transformation from their own praxis which would allow them to go through a process of learning, sharing, solving problems, and leading to social movements. This is similar to the method of giving poor people fish hooks rather than giving them fish. The government and people of any country understand better than anyone else clearly the strengths and characteristics of their homelands. It follows that they can efficiently contribute to causing poverty, preventing the return of poverty, and solving consequences of the poverty in their countries by many ways, especially a critical pedagogy; and indirectly narrow the scale of poverty in the world. In a word, the wars against poverty take time, money, energy and human resources, and they are absolutely not simple to end. Again, the poor and the challenged should be educated to be fully aware of their situation to that they can overcome poverty themselves. They need to be respected and receive sharing from the community. All forms of discrimination should be condemned and excluded from human society. When whole communities join hands in solving this universal problem, the endless circle of poverty can be addressed definitely someday. More importantly, every country should be responsible for finding appropriate ways to overcome poverty before receiving supports from other countries as well as the poor self-conscious responsibilities about themselves before receiving supports from the others, but the methods leading them to emancipation for their own transformation and later the social change.

AbstractAfrica’s need to double food production and feed the burgeoning human population, without compromising its natural resource base, has raised the momentum for sustainable agricultural intensification on the continent. Many studies describe agronomic practices that can increase productivity on existing agricultural land without damaging the environment and without increasing the agricultural carbon footprint. However, there is limited information on specific practices with the greatest potential to contribute to sustainable intensification on smallholder farms in sub-Saharan Africa, while simultaneously keeping the carbon footprint low. The objectives of this review were to (1) identify good agronomic practices with potential for contributing to sustainable intensification across sub-Saharan Africa, (2) synthesize available information on benefits and synergies from these technologies, and (3) discuss bottlenecks in their adoption in order to obtain insights that inform the formulation of supportive policies. Agroforestry, cereal-legume intercropping, conservation agriculture, doubled-up legume cropping, fertilizer micro-dosing, planting basins, and push-pull technology were identified as key agronomic innovations widely promoted in sub-Saharan Africa. We show that these innovations can build synergies and increase resource use efficiency while reducing agricultural carbon footprint. We outline the benefits, trade-offs, and limitations of these practices and discuss their potential role in strengthening food sovereignty and climate change adaptation and mitigation.

Abstract Background The burden of non-communicable diseases has been increasing in Sub-Saharan Africa, mainly due to the adoption of behavioral risk factors by the population. At the same time, there has been an exponential growth in the information and communication technologies sector, which has attracted interest in the development of mobile health strategies (mHealth) through the potential use of mobile phones in the management of chronic conditions such as hypertension. Methods It was performed a systematic review of the literature using scientific databases (Cochrane, B On, Science Direct, and Google Scholar). Inclusion criteria included: quantitative and qualitative studies developed between 2010 and 2018 in Sub-Saharan African countries, with adult participants of both sexes, diagnosed with hypertension, with access to mobile phones and attending primary health care or outpatient appointments. Results Five studies were selected for review (four from South Africa and one from Ghana). However, only two studies managed to obtain results which proved that the use of text messages was efficient and accepted during hypertension treatment, as well as it could allow understanding the factors that influence and hinder therapeutic adherence. Those results were supported by information from a randomized trial (use of clinical comparators as evaluation of blood pressure values during a follow-up period of 12 months) and a qualitative study (self-reported changes in the knowledge and health behavior of 15 participants from focus groups and individual interviews). Conclusions There's still a lack of evidence available proving that mHealth can be efficient and feasible in Sub-Saharan Africa. However, it was possible to present a conceptual framework, adapted from the literature, which identifies potential strategies for the use of mHealth in areas of prevention and management of chronic diseases in the region. Key messages Provide guidance to improve research about the adoption of mHealth in low and middle-income countries. Promote the potential of this type of technology as a model for mutual health education.

Sub-Saharan Africa has experienced unprecedented technological advancement, just like several other regions of the world. This improvement in technology lends credence to the proliferation of android mobile phones, laptops computers and the Internet facilities that enhance interaction on the social media which in turn generates momentous alterations in the ways the residents of the region construct their daily lives. From epidemiological perspective as well as the viewpoint of change and development, via these information technologies, rendering health-related care and services to the residents in the remote places of the region and gaining access to vital information that prompts prevention and control of diseases are now feasible unlike before the advancement. Therefore, telemedicine symbolizes a health innovation in the region. In the light of this, this paper systematically reviewed the extent to which telemedicine has gained acceptance among the residents of the region; and the socio-cultural factors and practices that promote and decelerate the general acceptance of telemedicine in the region. To accomplish the objective, the review was done meta-analytically and meta-synthetically to explore recent relevant studies. The paper discovered that reduction in the cost of gaining access to health information, harnessing online health and medical services, are among the benefits derived from telemedicine while fake online information, impoverished network service delivery, financial incapacity, theft, technical faults, underutilization of the technology devices and cyber-crime are among the factors that militate against wide acceptance of telemedicine in the region.

Studies abound on international migration and remittances across the world and studies are particularly not lacking on the subject in Africa. There are however few studies on the moderating roles of information communication technology (ICT) and social media in the relationships among international migration, remittances and relationships in Sub-Saharan Africa. This article examines the dimension of ICT and social media in migration studies. This is an aspect that has often been ignored and overlooked even though ICT and social media have great contributions in the international migration process particularly as migrants and relatives in sending and receiving countries both have the primary experience. Research objectives include: reasons for emigration; information technology/social media used by migrants and their kin as they relate across spaces; and how ICT affects relationships of kin and international migrants. Secondary data were gathered through journals, books, documents and reliable Internet sources. Primary data were gathered in Ibadan, Nigeria in 2018 through 30 in-depth interviews analysed through content analysis. Findings reveal the nature of ICT used by international migrants and their kin and purpose of utilization and the effects of ICT on international migration, remittances and kinship networks. The article presents detailed data, narratives, interpretations and implications of relationships among international migration, ICT/social media and kinship networks. This article argues that ICT/social media is central to international migration decision-making, access of migrants and kin to social forces and factors motivating international migration, and it is very important to how migrants and kin maintain and/or weaken relationships and access to remittances and utilization.

Information and communication technology (ICT) has emerged as a tool that can enhance flexible learning pathways. ICT has the potential to increase equitable access to quality learning, which is essential for skills development. Skills are required in technology-related nonfarm activities so as to improve livelihoods and achieve sustainable rural transformation. However, slow pace of the developing countries to utilize the benefits of the ongoing technological revolution in the North has resulted in the ‘digital divide’. Besides, it is still problematic to implement ICT programmes for educational development. The current and future challenges of providing ICT-based learning desperately call for the reengineering of education to move out of the formal structure of teaching and learning, towards building a more practical and realistic approach. By means of a literature review, this paper examines and discusses why it is important to provide inclusive, quality ICT-based learning, particularly in the rural areas of Asia and sub-Saharan Africa (SSA). It recommends that diverse ICT-based solutions be adopted to promote skills development and training within non-formal and informal settings. More comparative studies are also required to understand the impact of ICT-based learning in rural areas.

Abstract Background The rapid growth of mobile technology has given rise to the development of mobile health (mHealth) applications aimed at treating and preventing a wide range of health conditions. However, evidence on the use of mHealth in high disease burdened settings such as sub-Sharan Africa is not clear. Given this, we systematically mapped evidence on mHealth for disease diagnosis and treatment support by health workers in sub-Saharan Africa. Methods We conducted a scoping review study guided by the Arksey and O’Malley’s framework, Levac et al. recommendations, and Joanna Briggs Institute guidelines. We thoroughly searched the following databases: MEDLINE and CINAHL with full text via EBSCOhost; PubMed; Science Direct and Google Scholar for relevant articles from the inception of mHealth technology to April 2020. Two reviewers independently screened abstracts and full-text articles using the eligibility criteria as reference. This study employed the mixed methods appraisal tool version 2018 to assess the methodological quality of the included studies. Results Out of the 798 articles identified, only 12 published articles presented evidence on the availability and use of mHealth for disease diagnosis and treatment support by health workers in SSA since 2010. Of the 12 studies, four studies were conducted in Kenya; two in Malawi; two in Nigeria; one in South Africa; one in Zimbabwe; one in Mozambique, and one in Lesotho. Out of the 12 studies, one reported the use of mHealth for diseases diagnosis; three reported the use of mHealth to manage HIV; two on the management of HIV/TB; two on the treatment of malaria; one each on the management of hypertension; cervical cancer; and three were not specific on any disease condition. All the 12 included studies underwent methodological quality appraisal with a scored between 70 and 100%. Conclusions The study shows that there is limited research on the availability and use of mHealth by health workers for disease diagnosis and treatment support in sub-Saharan Africa. We, therefore, recommend primary studies focusing on the use of mHealth by health workers for disease diagnosis and treatment support in sub-Saharan Africa.

Abstract Background Cumulative data from several studies suggest that HIV-infected populations have a 2-fold increased cardiovascular risk. Evidence is also pointing to a link between HIV and early vascular changes, including endothelial dysfunction and subclinical atherosclerosis. There is a paucity of data from sub-Saharan Africa (the epicenter of the global HIV burden and a region with a rapidly increasing cardiovascular disease [CVD] incidence); furthermore, the contribution of specific combination ART (c-ART) regimens to HIV-related CVD and early vascular changes remain unclear. Purpose To investigate the association between HIV-infection, c-ART (TDF+FTC+EFV), CVD risk and vascular markers of CVD in an adult cohort in South Africa. Methods Cross-sectional study, participants assigned to 3 groups: HIV-free (HIV−), HIV-infected ART naïve (HIV+/−) and HIV-infected on ART (HIV+/+). Data collection: demographic information, anthropometrics, CVD risk factors, and blood chemistry. Vascular endpoints assessed: brachial artery flow-mediated dilatation (FMD), carotid intima-media thickness (C-IMT) and retinal microvascular calibers. Results Cohort size: n=427 (HIV− n=148; HIV+/− n=69; HIV+/+ n=210), mean age: 39.4 years, 68.9% females. Analysis of cardiovascular risk showed no differences in smoking and alcohol consumption, and blood pressure was unaffected by HIV-status. The untreated HIV group had a high % participants with clinically low HDL-cholesterol levels, whereas c-ART seemed to reduce the prevalence (HIV+/−: 58% vs 31% in HIV− and 26% in HIV+/+; p<0.01). Prevalence of hyper-LDL-cholesterolemia and hypertriglyceridemia were similar. High sensitivity CRP levels were unaffected by HIV-status. Markers of end-organ damage showed renal involvement in the HIV+ groups (median regression of urine albumin-creatinine ratio in HIV+/+ and HIV+/− vs HIV−: Beta±SEM: 0.5±0.3 and 0.8±0.2 in HIV+/+ and HIV+/− respectively, p=0.02; adjusted for age, gender and ethnicity), as well as hepatic injury in the treated group (gamma-GT in HIV+/+ vs HIV−: Beta±SEM: 23.3±4.4, p<0.01, adjustment as above). Multiple regression of vascular markers showed increased FMD in HIV+/+ vs HIV+/− (Beta±SEM: 1.8±0.8, p=0.01; adjusted for age, gender, ethnicity and BMI), and decreased central retinal venular equivalent (CRVE) in HIV+/+ vs HIV+/− (Beta±SEM: −11.9±3.8, p=0.002) and vs HIV− (Beta±SEM: −7.1±3.2, p=0.03), adjustment as above. Carotid IMT was not affected by HIV or treatment status. Conclusions Combination ART consisting of TDF+FTC+EFV conferred vascular protection in HIV-infected participants as shown by improved endothelial function (increased FMD) and smaller CRVE compared to ART naïve counterparts. There was no evidence of subclinical atherosclerosis involvement (C-IMT). The vasculoprotective effects in the treated group were supported by a favourable HDL-cholesterol profile, despite unchanged inflammation (hs-CRP), and evidence of renal and hepatic impairment.

Purpose This paper aims to chronicle perceived corruption cases emanating from poor records management in selected countries in sub-Saharan Africa by examining the nexus between records management and perceived corruption in Africa. Design/methodology/approach Using a content analysis approach, based on auditor’s report and detailed analysis of available literature, this study examines the nexus between records management and perceived corruption in Africa. Findings It observed that government agencies can easily be corrupted by inefficiencies in records management. However, a clear commitment to records management, underpinned by transparency and accountability, ensures that public office holders can be held accountable for their actions. Free and unhampered access to information promotes transparency in the administration of public funds and public participation. Research limitations/implications The study selected only 14 African countries for the study to establish the nexus between corruption and records management. Further studies are needed to cover all the countries in Africa. Practical implications The paper contributes to the ongoing debate that effective records management is crucially important in the prevention of corruption. It does this at a time when most African countries have made commitments towards the 17 goals of the 2030 Sustainable Development goals of the UN. The implementation of these goals can effectively be achieved in an environment where there is an effective records management system to ensure that public officers have access to information in the delivery of their duties. Originality/value The paper is written at a time when most African countries have made commitments towards the 17 goals of the 2030 Sustainable Development goals of the UN.

AbstractThe use of Information and Communication Technology (ICT) in education has been widely advocated as much needed 21st-century skills by governments and policymakers. Nevertheless, several challenges in integrating ICT into the curriculum have been reported in previous research, especially in studies on Sub-Saharan African countries. Focusing on the case of Kenyan public primary schools, this study investigated the availability of ICT facilities; teacher capacity to integrate technology into their lessons; and teacher perceptions towards technology in schools. In particular, the study is premised on the constructivist learning theory and the Technology Acceptance Model. A total of 351 teachers completed an online questionnaire. Teachers perceived that ICT facilities were inadequate in schools, which presented a challenge in the integration of technology during the implementation of the new curriculum. Most of the teachers answered that they received only basic computer literacy training. Although teachers perceived the use of computers as necessary, they faced difficulties integrating technology in their lessons. The effect of age and gender on teacher capacity was also investigated in inferential statistics, specifically with Welch tests and Games-Howell post hoc comparisons. Teachers in their 40s had a higher perception of usefulness than teachers in the 30s. Implications of the study are discussed as well as future research topics.

Abstract Background Interest in mHealth interventions, defined as the use of mobile phones to access healthcare is increasingly becoming popular globally. Given its technology-based applications, university students may be key clients of the mHealth adoption but studies are rare in sub-Saharan Africa. This study provides a snapshot and baseline evidence on knowledge, attitude and use of mHealth among university students in Ghana. Methods Using a self-administered questionnaire, we collected data between April and June 2017 from 963 randomly sampled undergraduate students at the Kwame Nkrumah University of Science and Technology (KNUST). Pearson’s Chi-square (χ2) test assessed the differences between variables whilst logistic regression models estimated the independent predictors of use of mHealth with p < 0.05 as significant. Results Knowledge on mHealth was moderately high. Specifically, more than half of the sample reported awareness of mHealth although the prevalence of use of mHealth stood at 51%. Logistic regressions revealed that mHealth use was positively associated with respondents’ year (second year: OR = 1.704, 95% CI: 1.185–2.452, and third year: OR = 1.528, 95% CI: 1.060–2.202), and monthly income (OR:3.112, 95%CI: 1.180-8.211). However, ethnicity [(OR = 0.761, 95% CI (0.580–0.997)] was negatively associated with the use of mHealth technology. Conclusion Findings suggest that knowledge of mHealth among university students is low. Policy and public health interventions for urgent awareness creation and promotion of use of mHealth as well as its possible integration into the mainstream healthcare system in Ghana are timely.

Abstract Background Anopheles coluzzii and Anopheles arabiensis belong to the Anopheles gambiae complex and are among the major malaria vectors in sub-Saharan Africa. However, chromosome-level reference genome assemblies are still lacking for these medically important mosquito species. Findings In this study, we produced de novo chromosome-level genome assemblies for A. coluzzii and A. arabiensis using the long-read Oxford Nanopore sequencing technology and the Hi-C scaffolding approach. We obtained 273.4 and 256.8 Mb of the total assemblies for A. coluzzii and A. arabiensis, respectively. Each assembly consists of 3 chromosome-scale scaffolds (X, 2, 3), complete mitochondrion, and unordered contigs identified as autosomal pericentromeric DNA, X pericentromeric DNA, and Y sequences. Comparison of these assemblies with the existing assemblies for these species demonstrated that we obtained improved reference-quality genomes. The new assemblies allowed us to identify genomic coordinates for the breakpoint regions of fixed and polymorphic chromosomal inversions in A. coluzzii and A. arabiensis. Conclusion The new chromosome-level assemblies will facilitate functional and population genomic studies in A. coluzzii and A. arabiensis. The presented assembly pipeline will accelerate progress toward creating high-quality genome references for other disease vectors.

Abstract Objectives To share our approach for designing, developing, and deploying the Research Electronic Data Capture (REDCap) Mobile Application, details about its dissemination and support through the REDCap Consortium, and a set of lessons learned and guidance recommendations for others developing mobile platforms to support research in regions or situations with internet scarcity. Materials and Methods We defined minimum viable product requirements centered around Android and iOS platform availability, data capture specifications and project initiation workflow, study data synchronization, and data security. After launch, we added features based on feedback from end-users and REDCap administrators. We prioritized new features based on expected impact, difficulty, and anticipated long-term cost for sustainability. Results We chose Apache Cordova, a combined iOS and Android development framework, based on targeted end-user technology expectations, available programmer resources, and the need to provide solutions for resource-limited settings. The REDCap Mobile Application was launched in 2015, has been enabled at over 800 REDCap Consortium partner organizations, and has supported diverse scientific studies around the world. Discussion Apache Cordova enabled early software releases for both iOS and Android, but required ongoing optimization efforts to improve software responsiveness. Developing a robust and efficient mobile device synchronization architecture was difficult without direct access to global network infrastructures for testing. Research teams in sub-Saharan Africa helped our development team understand and simulate real-world scenarios of intermittent internet connectivity. Conclusion Guidance recommendations based on designing, developing, deploying, and disseminating the REDCap Mobile Application may help other teams looking to develop clinical research informatics applications.
