The circular economy business models (CEBMs) provide ways for firms operating in the construction industry to move from a linear to a circular approach. Thus, this study aims to explore CEBM research within the construction sector to show the focus area of studies, highlighting new areas that require attention.

This study adopted a bibliometric approach, using the Scopus database as the data source. The keywords used for paper extraction from the database were “circular economy business” OR “circular business” AND “model” OR “models” AND “construction industry” OR “building industry”. The VOSviewer software was then used to prepare a co-occurrence and co-authorship map based on the bibliographic data gathered.

The study’s findings reveal five research clusters in the construction industry. These clusters include circular construction intelligence, modular business modelling, eco-construction, sustainable construction economics and smart energy-efficient buildings. The two most cited scholars had two publications each, while the top journals are the Journal of Cleaner Production and Sustainable Production and Consumption. This study concludes that there is a need for research within the construction sector to focus on CEBMs’ archetypes and frameworks. This will enable a smooth transition from linear to circular business models in the sector.

The information was gathered from a single database, Scopus; hence, using other databases, including Web of Science, Google Scholar and Dimensions, might produce more articles for examination and, consequently, different findings on the subject under investigation.

These findings would assist researchers in considering the areas mentioned, which are yet to receive attention, and, by extension, enhance economic development while maintaining environmental sustainability.

This paper made a significant contribution to the body of knowledge by identifying scholars and platforms that have been instrumental in advancing CEBM research and highlighting new areas that require attention in the construction sector.

This paper aims to examine the views of the global knowledge management (KM) community on the research area of KM and business performance and identify key future research themes.

An interview study spanning 222 informants in 38 countries was launched to collect data on KM expert views concerning the future research needs of the KM field.

The value contribution of KM requires more research despite experts agreeing on the complexities involved in solving this challenge. Further research areas identified were related to the influence of KM to support business strategy, intellectual capital, decision-making, knowledge sharing, organizational learning, innovation performance, productivity and competitive advantage.

The sample is dominated by European-based KM experts and the self-selecting sampling approach that was used by relying on the networks of each partner could have biased the structure of this sample.

The recognition of the complexity to demonstrate the value contribution of KM could prevent practitioners from using over-simplified approaches and encourage them to use more advanced measurement approaches.

The paper is unique, in that it reports on the views of 222 KM experts from 38 countries representing both academia and practice, on the issue of future research needs in terms of KM and business outcomes. As such it provides valuable guidance for future studies in the KM field and related subjects.

This study aims to assess the accessibility of women to health-care facilities in the rural areas with a view to unties possible recommendation of enhancing its service delivery. It provides an insight into the levels of satisfaction of the services provided by conventional health-care providers in the area where the majority in the developing countries concentrated. The study unravels the reasons for the low patronage of regular health-care facilities to boost unscientific ones by rural women.

The study relies on extensive field work conducted in the study area mainly rural nature. data was sourced by questionnaire, mainly administered on the women in the area and field observation. Data collected were analysed using descriptive statistics.

The paper provides information on the low socio-economic attributes of rural women. It is further showed that medical facilities and personnel were not relatively available and performed in health-care centres to the satisfaction of the users. Poor roads, poor human relation, low quality of services, inadequate medical personnel and drug shortage hindrance to women accessing appropriate health-care facilities in the rural areas. Rural women, therefore, opted for self-medication folk medicine, disguising and spiritual remedies. Health-care facilities suffered poor patronage as a result of these obstacles The study recommended proper overhauling of health-care facilities.

The paper builds a relationship on the reasons for health-care facilities neglect in the rural area in developing countries and revealed unscientific means by which health care needs are realised rural women.

This paper aims to investigate the stability of passive oxide film formed on the surface of 316L stainless steel in 3.5 Wt.% NaCl in the presence of two environmentally non-toxic inhibitors, i.e. leaf extracts of Musa spp. (MS) and Jatropha curcas (JC).

Current transients and potentiodynamic polarization curves were used to explain the stability of the passive film on Current transients and potentiodynamic polarization curves were used to explain the stability of the passive film on 316L stainless steel at both ambient temperature (25 °C) and 70 °C. For the potentiostatic tests, the coupons underwent cathodic stripping to remove the native oxide on their surfaces at −850 mV for 600 s, and a potential of 50 mV was imposed to observe the repassivation for 200 s. For the potentiodynamic tests, the pitting potential measured at 100 μA/cm2, corrosion potential and cathodic current density were obtained for analysis.

The current transients perfectly fitted into the exponential decay curve; i = i_s + i_peak exp(−t/τ), where the decay constant, τ measures the repassivating speed and extent to which the newly formed film heals and stabilizes. The current transients showed that MS and JC help in the repassivating process, especially at 300 ppm and 200 ppm, respectively, both at the lower temperature. The potentiodynamic curves mostly correlated with the current transients except for the hybrid inhibitor. The inhibitors increased the pitting potentials at concentrations that are correlated to their scanning electron micrograph images.

Because they are cheap and environmentally friendly, plant extracts that are proven corrosion inhibitors could be used to aid the formation of passive film on passive alloys in not-so-aggressive environments.

Both MS and JC improve the film stability mostly at intermediate concentrations of 200 and 300 ppm, respectively, at ambient temperature and 70° C.

Using leaf extracts of plants as green inhibitors is considered an environmentally friendly engineering solution.

The leaf extracts are a convenient resource of green inhibitors because their plants are readily available or could be easily naturalized, the processing technique to obtain the extracts is very cheap and the inhibitors are environmentally friendly. In addition, cathodic stripping exposes a relatively larger surface area than that obtained using the most common forms of depassivation; hence, the efficiency of the inhibitor in aiding the formation of the new oxide film to cover the bare surface would be better measured. There is very lean research data on the combined use of green inhibitors and cathodic stripping to study repassivating kinetics of passive alloys.

This study aims to explore the motivation as well as barriers for ethical food consumption behaviour by focussing on the food consumption pattern of young adults in the North East of Scotland. Considering the recent involvement of young adults in environmental activism, consumption behaviour of young adults in the North East of Scotland, an oil-based community, presents essential research interest to understand whether young adults often contemplate the consequences of their lifestyle.

The authors explored the perceptions of ten purposive recruited young adults using semi-structured interviews to understand factors underpinning consumer's decision-making towards ethical food products.

The study reveals three key factors influencing ethical food consumption behaviour among young adults. The findings show that personal health and well-being are the main reasons why consumers engage in ethical food consumption. Also, it is observed that information facilitates decision-making by raising awareness regarding the social, environmental and health consequences of food production and consumption. Further, the findings show that situational attributes, such as product price and product availability, are creating dissonance when engaging in ethical food consumption.

This study contributes to sustainability research and the ongoing debate on consumerism by exploring ethical food consumption behaviour and highlights the need to address situational challenges, such as product price and availability. The study suggests that interventions to address current consumption patterns should also emphasise the social and personal benefits of food consumption rather than the environmental benefits that have been the focus of prior research.

Being a novel public health crisis, the COVID-19 pandemic presented world leaders with difficult options and some serious dilemmas that must somehow be negotiated. Whilst these leaders had limited knowledge about the coronavirus and how the pandemic would potentially evolve, they were still expected to make high-staked judgements amidst a range of uncertainties. The purpose of this paper is to explore the response strategies used by various world leaders from the perspective of crisis leadership within the public health domain.

Secondary data was collected from research papers, policy reports and credible media outlets to examine the construct of crisis leadership within the context of the global pandemic.

The paper identified three cognitive antecedents to the COVID-19 crisis leadership failures, which helped to explain why certain policy decisions were successful and why others were less so. On this basis, a clear dichotomy was drawn between highly rated leaders and their less successful counterparts in relation to the management and governance of the coronavirus pandemic.

The uniqueness of this paper lies in its psycho-political approach, which offered insights into the cognitive undertones that underpin the three leadership failures that emerged from the distinct approaches used by world leaders to prepare for, respond to and recover from the COVID-19 pandemic. The practical recommendations proposed in this paper are hoped to aid better decision-making for leaders faced with the task of managing future public health crises.

The purpose of this paper is to assess the ethnicisation of corruption in Nigeria. This paper examines the role of ethnicity in promoting corruption, the impact of ethnicity on corruption and the challenge it poses for its combat.

The study uses descriptive analysis and evidence-based research.

The paper found evidence that corruption was deeply rooted in various ethnic groups that people Nigeria, and this is the major factor militating against measures to combat it. The findings are relevant for understanding the dynamics of corruption and strategies to combat it.

The paper’s uniqueness is its departure from the overly researched problems, consequences and causes of corruption to a new area of linking ethnicity to the virulent nature of corruption in Nigeria. It shows a number of evidences of ethnic dimension to corruption escalation in the country.

The purpose of this paper is to examine the effects of the implementation of the International Public Sector Accounting Standards (IPSAS) on Nigeria’s financial reporting quality.

The study employed a survey research design to determine the effects of the implementation of the IPSAS on Nigeria’s financial reporting quality. Partial Least Square 3(SmartPLS 3) technique of analysis was applied to achieve the research objective.

The study found that accountability positively and significantly affects the quality of financial reporting in Nigeria. Specifically, IPSAS has improved the level of accountability, which in turn improved Nigeria’s financial reporting quality.

The study only explored two explanatory variables whereas other variables such as transparency, corruption minimization, comparability and faithful representation were not considered in this study. It is, therefore, recommended that further studies could expand the scope to cover some other variables not included in this paper.

IPSAS-Accrual has engendered the Nigerian Government to launch the Asset Tracking and Management Project (ATMProject) in order to easily track its assets for the purpose of accountability. Thus, accountability was discovered in this study to be the most essential factor to enhance the quality of financial reporting using accrual-based IPSAS in Nigeria.

Accountability will impact positively on the lives of Nigerians in relation to the application of public funds to impact on the lives of the masses.

The statistical significance of accountability found in this study, using partial least square technique of data analysis, will further enhance financial integrity in the country.

This chapter theoretically examined coronavirus (COVID-19) and entrepreneurship in Africa. Also, the challenges and opportunities of small and medium enterprises (SMEs) innovation were assessed. The researchers adopted a qualitative method to review secondary data, information from previous kinds of literature including pertinent internet sources and working papers. Similarly, the chapter considered an innovative-based perspective of entrepreneurship and explicates the emerging opportunities created by COVID-19. The chapter also analyzed the COVID-19 and its effect on entrepreneurship in Africa by identifying and discussing existing challenges caused by the pandemic. Furthermore, some information about the nature of COVID-19 and its effects in Africa were adequately evaluated. Gleaned evidence from literature revealed that there is a possibility that the unpremeditated damage to entrepreneurship in Africa as caused by the COVID-19 could be persistent. The chapter also showed that the emergence of the COVID-19 has threatened the survival of businesses especially SMEs, thereby increasing the level of unemployment across the African continent and has generated critical challenges for entrepreneurship development. Finally, the chapter will add to the evolving challenges and opportunities of entrepreneurship in Africa. However, entrepreneurs can build on the strengths of innovative activities to develop a survival mindset, develop financial resilience and adjust business archetypes to the realities of COVID-19 and post-COVID-19 era which in the short and long term can accentuate entrepreneurship development within African continent.

The purpose of this paper is to examine different categories of building project procurement routes based on organisational, contractual, financial and technical issues.

The paper is based on review of literature and conditions of contracts. The UK construction industry serves as a general frame of reference. The Royal Institution of Chartered Surveyors survey of Contracts in Use from 1985 to 2004 is used to probe the share and value of contracts along different procurement routes and across different conditions of contracts in the UK. The logic is that the value and the share of contracts will indicate the behaviour of different procurement routes in the UK construction market while the in‐depth analysis of conditions of contracts will show the gaps and relationships between the general definition/categorisation and contractual context (conditions of contracts) of each of the procurement routes.

The preliminary result of the analysis shows that traditional routes remain the main type of procurement route for the construction project industry sector, within which different management and incentivisation systems are applied for greater efficiency. The conditions of contracts in the UK support this assertion by aligning different procurement routes to different conditions of contracts and additionally specifying different forms of agreements, special provisions and incentivisation in order to increase performance, reduce risks and improve compensation methods.

The study can serve as a learning opportunity for construction project stakeholders internationally, and clients in particular, to differentiate between procurement routes, management‐oriented systems, relational contracting and incentivisation.

The research provides an original assessment of construction procurement which can be used as intervening tool in different levels of private and public procurement strategies.
