Sustainable/Green building materials (SBMs/GBMs) offer a wide range of benefits which cut across the economic, social and environmental dimensions of sustainability. The incorporation of these materials in construction projects in most developing countries is still low owing to some factors. This study assessed the major barriers to the incorporation of SBMs in the delivery of construction projects in developing countries, with Nigeria as a case in point.

The well-structured quantitative questionnaire was used to gather data from the key players in the construction industry, using the snowball sampling method and electronic means of questionnaire administration. Frequencies, percentile, relative importance index, Kruskal–Wallis H test, Kendall's coefficient of concordance and exploratory factor analysis were used to analyse the gathered data.

The study revealed that the major constructs of barriers to SBM adoption in construction projects are: (1) resistance and information barriers (Eigenvalues = 5.237; % of V = 23.806), (2) regulation and funding of R&D (Eigenvalues = 2.741; % of V = 12.457), (3) cost and market barriers (Eigenvalues = 2.223; % of V = 10.105), (4) government incentive and suppliers' availability (Eigenvalues = 1.728; % of V = 7.852) and (5) GB experts and labour barriers (Eigenvalues = 1.307; % of V = 5.942).

This study assessed the view of construction experts in the five states of the south-eastern geo-political zone of Nigeria, particularly as regards the barriers to the incorporation of sustainable building materials in construction projects in the region.

The purpose of this study is to assess the potential benefits of digital technologies (DTs) in bolstering the circular economy (CE) transition in the construction industry, to speed up the attainment of sustainable development objectives.

A detailed literature review was undertaken to identify DTs that could influence CE transition and the benefits of these DTs in the CE transitioning efforts of the construction industry. Based on these, a survey questionnaire was formulated and administered to construction professionals using convenient sampling techniques. With a response rate of 49.42% and data reliability of over 0.800, the gathered data were analysed using frequency and percentage, mean item score, normalisation value, coefficient of variation, Kendall’s coefficient of concordance, analysis of variance and factor analysis.

This study found that the construction experts agreed that building information modelling, blockchain technology, RFID, drone technology and cloud computing are the leading DTs that have the potential to influence and speed up CE transition in construction. Also, six clusters of benefits of DTs in bolstering EC are quicken CE transition, proactive waste management, recycling and zero waste, data management and decision-making, enhance productivity and performance and resource optimisation.

Studies on the integration of DTs in CE transition are scarce and it is even lacking in the Nigerian context. To the best of the authors’ knowledge, this study is the first to assess the role of DTs in CE transitioning in the Nigerian construction industry.

The purpose of this study is to investigate barriers to the adoption of digital technologies (DTs) in the circular economy (CE) transition in the construction industry. The aim is to quantitatively investigate what the barriers to DTs-driven CE are in the Nigerian construction industry.

A review of existing literature identified 32 barriers to DTs-led CE. A well-structured quantitative research questionnaire was developed and administered to construction experts using a convenient sampling technique via hand delivery and Google form. The gathered data were analysed using arrays of both descriptive and inferential statistical methods.

The study revealed that the awareness of the digitalisation of CE is high, but the adoption is low. Five themes of the leading 10 factors responsible for the low adoption of DTs in CE transition in the Nigerian construction industry are (1) finance and demand barrier, (2) data management and information vulnerability, (3) skills shortage and infrastructure challenge, (4) poor government and management support and (5) interoperability and resistance problems.

This study could be helpful to decision-makers and policy formulators, which would provide an avenue for higher adoption of DTs in CE transition in the construction industry, better performance and environmental protection. It also provides a foundation for further research efforts in Nigeria and other developing countries of Africa and beyond.

Studies on the barriers to DT adoption in CE transition are still growing, and this is even non-existent in the Nigerian construction context. This offers a unique insight and original findings by pioneering the identification and assessment of barriers to the digitalisation of CE transition in Nigeria’s construction industry.

This paper aims to present the result of an assessment of the potential effect of building information modelling (BIM) adoption on the reduction of construction waste (CW) from a developing country's perspective. This was done with a view to reducing the waste generated in construction projects particularly at the design and pre-contract stages.

The study adopted a post-positivism philosophical approach, which informed the use of a quantitative research design and a questionnaire as instrument for data collection. The data gathered from construction professionals in the Nigeria construction industry were analysed using an array of statistical tools such as frequency, percentage, Kruskal–Wallis H-test, Kendall's coefficient of concordance, chi-square and exploratory factors analysis.

The study revealed five major groups of factors causing CW at the design and pre-contract stages that can be avoided or minimised through BIM implementation. These are; (1) errors in design and documentation, (2) specification and quality factors, (3) estimating and site condition factors, (4) planning of work factors and (5) procurement related factors.

The findings of the study offer practical insight for industry participants on the need for BIM implementation to reduce CW by identifying the diverse areas responsible for these waste generation.

While there has been significant literature on BIM implementation, contributions on the effect of this technology in reducing waste generation particular at the design and pre-contract stages in developing countries has been almost non-existent. This study strives to fill in this gap by showcasing the major waste generating activities that can be avoided through the use of BIM.

Lack of strict compliance to the principles of total quality management (TQM) by construction organizations has brought about poor quality of the finished building projects. This has been blamed for the incessant structural failure reported in Nigeria. This study appraised TQM implementation in the Nigerian construction industry, with a view to mitigating structural failure rate of construction projects. To achieve this aim, the study aims to assess the practice level of TQM and the factors hindering TQM implementation on construction projects.

The study utilized a well-structured questionnaire and convenient sampling method in the gathering and sampling of data among construction professionals in Imo state, Nigeria. Data analyses were done using, frequency, percentage, mean analytics and Pareto analysis.

The study revealed that major practice of TQM principles with respect to structural failure rate are purchasing: ensuring the procurement of materials of the specified quality standard, ensuring the use of a quality improvement construction process of the organization, site management responsibility: this entails ensuring quality supervision by the project management leadership and monitoring and control of quality during the construction to guarantee firm observance quality standards. Also, the major factors hindering TQM implementation on construction projects are: inadequacy of the necessary machineries, equipment, tools and facilities for the effective execution of work on construction site; breakdown in communication and information exchange between the management and supervisory teams on site; poor attitudes and strategies toward maintenance of equipment, tools and machines; and absence of prompt salary and incentive payment. It was recommended that construction firms must require the suppliers of construction materials to strictly comply with quality specification evidence in quality certification of delivered materials to mitigate structural failure.

This study appraised TQM implementation in the construction industry of Nigeria, with emphasis on Imo state. The study underscores the practice level of TQM and the key factors hindering TQM implementation on construction projects. Following the localized geographical limitation of the study area, a similar research in other part/states of Nigeria or even in other developing countries of African is necessary.

The practices level of TQM and the factors hindering TQM implementation were identified. This will be useful in guiding construction firms, other industry's key stakeholders and regulatory agencies in bringing about a sustainable quality management system for improve profit and value maximization and avoiding incessant structural failure.

This is one of the few studies that have assessed the practice level of TQM and the factors hindering TQM implementation on construction projects in Nigeria. This study took place in Imo state with records of periodic structural failure and building collapse.

The implementation of mobile health (mHealth) in developing countries seems to be stuck in a pattern of successive pilot studies that struggle for mainstream implementation. This study addresses the research question: what existing health-related structures, properties and practices are presented by rural areas of developing countries that might inhibit the implementation of mHealth initiatives?

This study was conducted using a socio-material approach, based on an exploratory case study in West Africa. Interviews and participant observation were used to gather data. A thematic analysis identified important social and material agencies, practices and imbrications which may limit the effectiveness of mHealth apps in the region.

Findings show that, while urban healthcare is highly structured, best practice-led, rural healthcare relies on peer-based knowledge sharing, and community support. This has implications for the enacted materiality of mobile technologies. While urban actors see mHealth as a tool for automation and the enforcement of responsible healthcare best practice, rural actors see mHealth as a tool for greater interconnectivity and independent, decentralised care.

This study has two significant limitations. First, the study focussed on a region where technology-enabled guideline-driven treatment is the main mHealth concern. Second, consistent with the exploratory nature of this study, the qualitative methodology and the single-case design, the study makes no claim to statistical generalisability.

To the authors' knowledge, this is the first study to adopt a socio-material view that considers existing structures and practices that may influence the widespread adoption and assimilation of a new mHealth app. This helps identify contextual challenges that are limiting the potential of mHealth to improve outcomes in rural areas of developing countries.

The modern prison system is not only a necessity to keep the public safe but also a mode of punishment for crimes. The correctional role of prisons is hampered in situations of mental illness, given that mental illness in the prison or correctional setting is a serious security risk. Few studies have given attention to the modifiable factors that may influence the mental health status of prison inmates, especially in developing countries. The purpose of this paper is to investigate emotion regulation (ER), dispositional mindfulness and duration of stay as factors in somatic symptoms among prison inmates.

Participants were 209 prison inmates drawn from a prison in Eastern Nigeria, who completed measures of ER (cognitive reappraisal and expressive suppression), mindfulness and somatization.

Results of a hierarchical multiple regression indicated that cognitive reappraisal predicted somatic complaints but it was only among older prison inmates, while expressive suppression was not a significant predictor of somatic complaints. Dispositional mindfulness was a negative predictor of somatic complaints among younger and older prison inmates. Duration of stay in prison positively predicted somatic complaints among prison inmates in emerging adulthood only (younger inmates), but not among older inmates.

Frequent use of cognitive reappraisal strategy of ER by prisoners may not always be productive in reducing somatic complaints, and the length of time in prison may influence somatic symptoms especially for younger prisoners. The possible benefits of incorporating mindfulness-based therapies in psychosocial interventions to reduce somatic complaints in correctional settings deserves further investigation.

To date, there is limited research on somatic complaints of prisoners in the developing societies, particularly the psychosocial factors that may contribute to mental health problems.

Emphasis of previous research on e-banking has been on factors that influence its adoption or constraints to the adoption or the extent to which customer awareness influences its adoption. This study investigated “Exposure to/usage of e-banking channels: Implications for customer awareness and attitude in Nigeria”. The purpose of this paper is to determine the extent to which consumers’ exposure to and usage of e-banking channels influence their awareness and attitude towards e-banking in Nigeria.

The study used the quantitative research design; specifically, the conclusive research design was used and data collection was done through the survey method. The population of the study consisted of the customers of EcoBank, First bank and Zenith bank in Edo, Kogi and Kwara states of Nigeria. A structured questionnaire was used to elicit the desired data from 480 respondents selected from 30 branches of 3 banks in two states. One sample t test was used to test for significance of the usage of e-banking channels to customers’ awareness and attitude towards e-banking. Subsequently, regression analysis was performed to determine the predictive power of the e-banking channels.

Customers’ exposure to and usage of ATM, internet banking and mobile banking has significant influence on consumers’ attitude towards e-banking in Nigeria. In view of the findings, a modified model of customer usage and attitude towards e-banking in Nigeria is proposed.

The customer’s inability to exercise absolute right on the banking option to use at all times and the non-inclusion of other channels of e-banking whose usage can influence consumers’ awareness and attitude towards e-banking.

The need for financial institutions, especially banks, to expose their customers to e-banking channels to demystify their fears as well as increase their awareness and thus influence their attitude to e-banking.

Exposure of bank customers to e-banking will reduce cash transactions and thus help to significantly reduce social vices associated with physical cash, especially armed robbery.

The work is a departure from previous studies because it is the only one that has emphazised exposure to e-banking as a solution to awareness creation and positive attitude of customers. Its value lies in its potential to make e-banking user friendly in no distance time.

The purpose of this study is to know the various factors librarians consider while selecting open access (OA) journal for publication, and to know the challenges librarians face with OA journal publishing.

Online questionnaire was designed to collect data using SurveyMonkey software from 335 academic librarians in 57 institutions (Universities, Polytechnics and Colleges of Education) in Nigeria.

The findings of the study revealed that majority of the academic librarians are aware of the gold and green publishing routes, while the majority of academic librarians are not aware of the diamond publishing route. The study also revealed that when considering where to publish, reputation and impact factor of journal were rated as very important among the factors that inform their choice of OA. The study further revealed that academic librarians have little or no knowledge about the existence of institutional repositories in their institutions, and only a few actual use institutional repositories and ResearchGate to self-archive their publications. The majority of the academic librarians agreed that author fees (Article Processing Charges) and low impact factor of journal are barriers to publishing in OA journals. Training on OA publishing is recommended for librarians to increase their knowledge and confidence to discuss OA with faculty members in future.

Knowledge of authors’ attitude toward OA publishing models will help OA advocates focus on the factors that are meaningful that are raised in this study.

The study is an original research work that investigated academic librarians’ perception and engagement with OA publishing as they lead the OA campaign in their institutions.

The purpose of this study was to investigate the likely causes of failure of some sections of road pavements in Ajaokuta, Northcentral Nigeria. This was achieved through a geotechnical assessment of subgrade soils in affected areas.

The methods entailed field and laboratory methods and statistical analysis. Subgrade soil samples were retrieved from a depth of 1,000 mm beneath the failed portions using a hang auger. The soils were analyzed for natural moisture content (NMC), Atterberg limit (liquid limit, plastic limit and linear shrinkage), grain size distribution, compaction and California bearing ratio (CBR), respectively.

The results of the geotechnical tests ranged from NMC (12.5%–19.4%), sand (84%–98%), fines (2%–16%), LL (16.0%–32.2%), PL (17%–27.5%), LS (2.7%–6.4%), PI (2.5%–18.4%), maximum dry density (1756 kg/m2–1961 kg/m2), optimum moisture content (13.2%–20.2%), unsoaked CBR (15.5%–30.5%) and soaked CBR (8%–22%), respectively. Pearson’s correlation coefficient performed on the variables showed that some parameters exhibited a strong positive correlation with r2 > 0.5.

Funding was the main limitation.

Comparing the results with Nigerian standards for road construction, and the AASHTO classification scheme, the subgrade soils are competent and possess excellent to good properties. The soils also exhibited very low plasticity, a high percentage of sand, high CBR and low NMC, which implies that it has the strength required for road pavement subgrades. The likely causes of the failures are, therefore, due to the use of poor construction materials, technical incompetence and poor compaction of sub-base materials, respectively.
