Yam flour (YMF) is an important staple food in the tropics but its utilization is limited by low nutrient and consumer acceptability. The aim of this paper is to investigate the effect of substituting yam flour with grain amaranth on chemical and sensory properties.

YMF and grain amaranth flour (GAF) were prepared on a dry matter basis; GAF was mixed with YMF at ratio 1:3. All flour samples were subjected to chemical (moisture, protein, fat, ash, crude fibre, carbohydrate and minerals) evaluation and sensory evaluation of the stiff gel was conducted by a ten‐member panel consisting of five adult males and five females.

GAF increased the protein content of YMF significantly at p < 0.05 from 1.8 to 9.63 per cent. There was a decrease in carbohydrate content of YAF when substituted with GAF. There was a significant increase (at p < 0.05) in phosphorus and sodium elements when YMF was substituted with GAF. There was no significant difference in acceptability of gel from grain amaranth and yam flour (GAF–YMF) compared with whole YMF gel on colour, texture, flavour and overall acceptability.

It was apparent that substitution of YMF with GAF improved nutrient composition without affecting the acceptability. This will further improve the nutritional status of people in YMF‐consuming areas.

To deal with the present situation and recover after the COVID-19 pandemic, construction firms are required to recognise the trends in construction supply chain management (CSCM) for the upcoming years and determine the appropriate practices towards the trends for the improvement of construction activities in terms of strategy, tactic and operations. This paper aims to recognise key trends in CSCM and uses these trends as strategic criteria for the evaluation and prioritisation of lean construction (LC) tools at different project phases including design and architectural engineering, planning and control, on-site construction and safety management.

The integrated analytic hierarchy process–Delphi method is used to collect and analyse the data from construction experts to evaluate the importance levels of the CSCM trends and recommend the appropriate tools for LC practices to improve project performances.

Seven key CSCM trends are identified: lean supply chain management (SCM), supply chain (SC) integration, SC standardisation, SC problem-solving, SC information-sharing, SC flexibility and SC sustainability. Based on these trends, a set of prioritised lean tools are suggested for LC practices, in which “virtual design construction” (VDC) and “last planner system” are considered as the central tools. These two LC practices can be integrated with other effective tools to support the strategic, tactical and operational targets in construction supply chain (CSC) projects.

This study gives the managerial implications by developing an application framework of LC practices for CSC projects. The framework promotes “VDC” as a strategic tool for the phase of design and architectural engineering and considers “last planner system” as the central LC practice for the phase of project planning and control. The framework also focuses on the improvement of efficiency in construction operations by taking into account the aspects of on-site collaboration, problem-solving, improvement and safety.

Up to date, there is still a lack of researches in classifying and prioritising the significant LC tools for each project phase to deal with CSC issues in both breadth and depth. Thus, this study is performed to provide construction managers with the awareness of CSCM trends on which they can focus to have strategic criteria for selecting LC practices to improve CSC performances.

This paper investigates the effect of abnormal increase in credit supply on economic growth in Nigeria after controlling for the quality of the legal system, size of central bank asset, banking sector cost efficiency and bank insolvency risk.

The authors employ the generalised method of moments (GMM) regression methodology to estimate the effect of abnormal increase in credit supply on two measures of economic growth in Nigeria.

The abnormal increase in credit supply has a significant effect on economic growth. Abnormal increase in credit supply increases real gross domestic product (GDP) growth. The abnormal increase in credit supply decreases real GDP per capita during the global financial crisis. The abnormal increase in domestic credit to the private sector has a significant positive effect on GDP per capita when there is strong legal system quality in Nigeria. In contrast, the abnormal increase in domestic credit to the private sector has a significant negative effect on real GDP growth when there is strong legal system quality in Nigeria.

The abnormal increase in credit supply is ineffective in increasing GDP per capita during crisis years. Policymakers should be cautious in pressuring financial institutions to release an abnormally large amount of credit into the economy particularly during financial crises. Rather, policymakers should encourage financial institutions to supply credit in a sustained manner – not in an abnormal manner –and in a way that supports growth.

The present study contributes to the literature by analysing the effect of abnormal increase in credit supply on economic growth in a developing country context.

Vernacular and modern architecture have mostly been seen as antitheses, impossible to reconcile, especially in Africa. They appear to belong to different ages, utilize different materials and methods, and encourage or support different lifestyles. This paper aims at seeking points where a merging of principles may be attempted between the two positions.

The study is based on a survey on the traditional architecture of the Yoruba people of West Africa. The decline in popular use of this building tradition and its rejection by design practitioners raises some physical and psychological issues which are examined in this paper. These include: spatial layout, use and quality, ecology and economy, concepts, meaning and perception. The fate of Yoruba traditional built culture depends on a conscious attempt to reconcile it with people's contemporary needs, lifestyles and world views.

Therefore, a brief introduction on the importance of Yoruba architecture and its preservation will be followed by a general definition of its features and characteristics, advantages and disadvantages. Finally, the problems posed by the architecture's modern trends in Yoruba land will be examined. It is hoped that such works may assist in the development of a truly responsive and sustainable architecture for the Yoruba people. The proposed solutions may be applied in other parts of Africa, or in regions with similar cultural or geographical concerns.

Innovation is not just an individual act of learning by a firm or entrepreneur, but anchored within a larger system that enables and draws on the innovation process. Hence there is need to study internal and external factors that influence technological innovation outputs of small and medium enterprises (SMEs). SMEs at four industrial estates in Nigeria were sampled for this study. Several internal factors such as firm size, turnover, age, ownership, and expenditure on innovation activities did not have significant relationships with innovation output, signifying they are not the factors promoting innovation levels. Quality of human resources and interactions with suppliers as an external factor within the national innovation system (NIS) both made significant impact on innovation. Innovative performance of the firms is mainly influenced by demand or market pull factors more than technology push sources. The study recommends increasing interaction and dynamism within the NIS; substantial investment to galvanize industrial and technological capabilities of the firms and their supply chains; and adequate supply of infrastructure and funds to SMEs.

This study delves into the factors that influence the practice of female genital mutilation in West Africa, as well as the health implications. An online cross-sectional study was conducted with the use of electronic questionnaire. The study was targeted at adult females who were between the age of 18 and 50 years old. The Uniform Resource Locator (URL) of the electronic questionnaire was administered on social media platforms (Facebook and WhatsApp) only through convenience and snowball sampling techniques. A sample size of 3,119 adult females participated in the study. Spearman rank correlation (r) was employed to test the hypotheses. Responses were gathered from adult females whom originates from nine West African countries which are Nigeria, Ghana, Mali, Liberia, Benin, Cameroon, Chad, Gambia and Guinea. The study found a strong and positive relationship between culture and the practice of female genital mutilation in West Africa, and there was a weak and positive relationship between religion and education, and the practice of female genital mutilation in West Africa. Despite the health risks, it was revealed that female genital mutilation remained uninterrupted in West Africa. The findings of this study imply that the culture of the people, religious belief system and education are critical factors in efforts to be considered when discouraging the practice of female genital mutilation. Therefore, for healthy living, the practice of female genital mutilation should be discouraged in the study area. Based on the study outcome, recommendations were suggested.

The concept of entrepreneurship is not new. As a concept, it remains elusive, diverse and multi-faceted. Although there is an extensive body of research within the field, there is little consensus on what underpins entrepreneurship, and whether it should remain a distinct domain of study.

This chapter contributes to the literature on entrepreneurship in developing economies. The study seeks to uncover the challenges facing entrepreneurs in a developing economy using the formal retail sector in Nigeria as a case.

Entrepreneurship in the retail sector of a developing economy has not been given significant attention by researchers despite its uniqueness and dynamism. By adopting a qualitative approach involving semi-structured interviews of 51 respondents, the lived experiences of these entrepreneurs were understood. Given the challenges such entrepreneurs face in a developing economy, this study makes a contribution, as the challenges such retail entrepreneurs face namely, challenges within the industry, government policy inconsistencies and corruption, infrastructural deficit and technology deficit were identified. In practice, the findings of this study serve as a useful reference for practitioners and policy-makers of the challenges that need to be addressed for entrepreneurship to flourish in Nigeria.

Incidents of violence perpetrated through digital technology platforms or facilitated by these means have been reported, often in high-income countries. Very little scholarly attention has been given to the nature of technology-facilitated violence and abuse (TFVA) across sub-Saharan Africa (SSA) despite an explosion in the use of various technologies. We conducted a literature review to identify and harmonize available data relating to the types of TFVA taking place in SSA. This was followed by an online survey of young adults through the SHYad.NET forum to understand the nature of TFVA among young adults in SSA. Our literature review revealed various types of TFVA to be happening across SSA, including cyberbullying, cyberstalking, trolling, dating abuse, image-based sexual violence, sextortion, and revenge porn. The results of our online survey revealed that both young men and women experience TFVA, with the most commonly reported TFVA being receiving unwanted sexually explicit images, comments, emails, or text messages. Female respondents more often reported repeated and/or unwanted sexual requests online via email or text message while male respondents more often reported experiencing violent threats. Respondents used various means to cope with TFVA including blocking the abuser or deleting the abused profile on social media.

This paper aims to measure the extent of effects of insurance fraud on the financial performance of insurance companies in Ghana. It also examines the causes and stringent measures that can be used to fight against insurance fraud.

Primary and secondary data obtained from 39 insurers in Ghana are used in this paper. A multiple regression model is used to determine the relationship between financial performance and insurance fraud variables.

The results from the model indicate that statistically insurance fraud has a significant negative effect on the annual return on assets (financial performance) of insurers in Ghana. Also, weak internal controls, poor remuneration of employees, falsified documents, deliberate acts of policyholders to profit from the insurance contract and inadequate training for independent brokers are found to be the major causes of insurance fraud in Ghana. To deter insurance fraud, effective internal fraud policy, rigorous assessment of insurance policies and claims, adequate training for independent brokers on insurance fraud and modern information technology tools are paramount in fighting this menace in Ghana.

These findings are to have substantial impact on the techniques insurance companies will develop to fight insurance fraud and the policies that will be developed by governments and national insurance regulatory bodies to fight this menace.

The main value of this paper is the determination of the key variables that constitute insurance fraud and their impacts on the annual financial performance of insurance companies in Ghana.

Small- and medium-sized enterprises (SMEs) within the construction sector are highly vulnerable to disruptions caused by political and economic decisions or even pandemics. This study evaluated the current operations of selected SMEs providing engineering design and consultancy services against Toyota Production System (TPS) lean tool. The purpose is to juxtapose SME operations and processes with TPS to ascertain the level of their operations conformity to the established TPS lean thinking tool.

This study used a qualitative data collection and analysis approach to evaluate the current processes of participating SMEs against Liker's 14 management principles of TPS. The data collected were analysed using thematic analysis to identify patterns and themes that emerged from the qualitative data.

The analysis revealed that focus on short-term goals, immediate profit and duplication of effort resulting from insufficient collaboration is currently creating waste in participating SMEs' operations. Hence, the implementation of TPS was recommended as a lean tool and a framework based on TPS lean tool was developed for improving the operations of SMEs.

The study is limited to SMEs operating only as consultants providing project planning design within the construction industry. Data collection is limited to qualitative even though observations would improve the outcome of the study.

The study advances contemporary issues in promoting lean implementation in construction sector and developed an improved framework based on the TPS to enhance the performance of SME construction businesses.
