Artificial intelligence (AI) has received much attention due to its promethean-like powers to transform the management and delivery of public sector services. Due to the proliferation of research articles in this context, research to date is fragmented into research streams based on different types of AI technologies or a specific government function of the public sector (e.g. health, education). The purpose of this study is to synthesize this literature, identify challenges and opportunities, and offer a research agenda that guides future inquiry.

This paper aggregates this fragmented body of knowledge by conducting a systematic literature review of AI research in public sector organisations in the Chartered Association of Business Schools (CABS)-ranked journals between 2012 and 2023.

The search strategy resulted in the retrieval of 2,870 papers, of which 61 were identified as primary papers relevant to this research. These primary papers are mapped to the ten classifications of the functions of government as classified by the Organisation for Economic Co-operation and Development (OECD), and the reported challenges and benefits aggregated.

This study advances knowledge by providing a state-of-the-art of AI research based the OECD classifications of government functions, reporting of claimed benefits and challenges and providing a research agenda for future research.

In less than a decade to Sustainable Development Goals, the urban solid waste (USW) emanating from households, especially in developing countries, calls for concern. Several policies have been suggested and some implemented, but the challenges facing USW management remain, especially in developing nations. Past studies demonstrated that the fourth industrial revolution (4IR) technologies can be used to improve urban public services. The role of 4IR in mitigating the challenges of USW is yet to receive in-depth research in Nigeria. Thus, the study investigated 4IR role regarding mitigating the challenges facing USW.

Seven cities across Nigeria, including the Federal Capital Territory, were used as the study area to achieve the research objectives via a qualitative research design. Thirty-two semi-structured interviews were conducted from selected regulators, households, legislators, ICT experts, NGOs and waste managers. A thematic approach was adopted to analyse the collated data.

Findings group the USW challenges into five categories. The 4IR technologies can be used to manage USW; thus, they create an opportunity to integrate and promote sustainable clean cities.

This study is confined to the 4IR role concerning mitigating the encumbrances facing USW in Nigeria and proffered feasible policies to enhance a sustainable healthy environment.

Proffered policy solutions will stir policymakers and construction practitioners to think outside the box and offer and better understand how 4IR technologies can be utilised to mitigate those challenges. The outcome will create sustainable clean cities as part of the implication contribution to the body of knowledge.

Evidence from the reviewed literature shows a paucity of literature focussed on 4IR roles in mitigating the encumbrances facing USW in Nigeria. Therefore, this study contributes to the existing research work on 4IR concerning its role in enhancing USW in Nigeria and, by extension, to other developing countries.

The construction industry is unique but with uncertainties. This is because of the operating environment. This intricacy gives rise to several construction risks and is compounded in developing countries’ turbulent times. If not managed, these risks enhanced in turbulent times could negatively impact the Nigerian construction projects’ cost, time, quality, and performance. Hence, this study investigated the perceived encumbrances facing construction risk management techniques and identified measures to promote sustainable-based construction risk management in turbulent times.

The researchers adopted a qualitative approach and achieved saturation with 28 participants. The participants were government policymakers, quantity surveyors in government ministries/agencies/departments, consultant engineers, consultant architects, consultant and contracting quantity surveyors, and construction contractors knowledgeable about construction risk management. The research employed a thematic analysis for the study’s data.

Findings identified turbulent times related to the industry and major techniques for managing construction project risks in the Nigerian construction industry. It revealed lax adoption and implementation of practices. Also, the study identified major encumbrances facing construction risk and proffered initiatives that would promote sustainable-based construction risk management in turbulent times.

This study investigates encumbrances and suggests measures to promote construction project risk management in turbulent times in Nigeria. Also, the study contributes to the literature’s paucity, uncovering perceived encumbrances and evolving organisations’ management styles to imbed sustainable-based risk management practices by qualitative research design method.

The purpose of this study is to investigate the financial well-being and social capital of Indian retirees. The paper investigates the extent of subjective financial well-being, the dependence on debts and the extent of bridging and bonding social capital of retirees with similar retirement pensions to understand the main issues they face.

Semi-structured interviews were conducted with 32 retired government schoolteachers. Two individuals transcribed the interviews after a pilot study, which helped remove repetitive responses. After ensuring the authenticity of the transcripts, the data was analyzed using interpretive phenomenological analysis.

The study's key findings reveal that retirees, armed with a clear understanding of their retirement income, exhibit a sense of financial control. At the same time, the presence of debt and the potential for high healthcare expenses adversely impact their subjective financial well-being. In terms of social capital, retirees predominantly rely on support from close-knit communities of friends and neighbors, as against their children. Additionally, retirees who migrate from their native places encounter challenges in establishing bridging social capital.

This study contributes to the ongoing discourse on financial well-being, specifically within the context of vulnerable groups such as retirees in India, where the absence of a state-supported retirement system adds a distinctive dimension. Against the backdrop of India's traditional societal framework, the research extends the existing literature by delving into the nuanced effects of evolving social dynamics on the social capital of retirees.

Studies show that building information modelling (BIM) technology can improve construction productivity regarding the design, construction and maintenance of a project life cycle in the 21st century. Revit has been identified as a frequently used tool for delivering BIM in the built environment. Studies about BIM technology via Revit are scarce in training middle-level workforce higher education institutions. Thus, this study aims to investigate the relevance of BIM technology and offer measures to promote digitalisation in Nigeria’s built environment polytechnic undergraduates via Revit.

Given the unexplored nature of training the middle-level workforce in Nigeria, 37 semi-structured virtual interviews were conducted across Nigeria, and saturation was achieved. The participants were knowledgeable about construction-related BIM. The researchers used a thematic analysis for the collected data and honed them with secondary sources.

Improved visualisation of design, effective and efficient work productivity, automatic design and quantification, improved database management and collaboration and data storage in the centrally coordinated model, among others, emerged as BIM’s benefits. BIM technology via Revit is challenging, especially in Nigeria’s polytechnic education curriculum. The 24 perceived issues were grouped into government/regulatory agencies-related, polytechnic management-related and polytechnic undergraduate students-related hindrances in Nigeria’s built environment.

This study is limited to BIM implications for Nigeria’s built environment polytechnic undergraduates.

This study contributes to the literature paucity in attempting to uncover perceived issues hindering the implementation of BIM technology via Revit in training Nigeria’s built environment polytechnic undergraduates via a qualitative approach.

The paucity of artisans in some construction trades and the transitioning of the experience of the few for sustainability calls for concern. Mentorship programmes offer a promising mechanism to support construction artisans through those transitions. Mentorship may enhance artisan decent work and economic growth, like increased income for artisans. This is part of Sustainable Development Goal 8 (Goal 8). Hence, this study aims to investigate issues hindering construction artisan skills growth and suggest measures to improve construction artisan skills through mentorship mechanisms to achieve Goal 8.

The study adopted a qualitative approach and collected data via oral interviews with knowledgeable participants. The participants were consultant experts in mentorship and Sustainable Development Goals (SDGs) matters, construction organisation management staffers and construction artisans in the Nigerian construction industry. The study covered Lagos and Abuja and achieved saturation at the 30th interviewee. Also, the research utilised a thematic method to analyse the collated data.

Enhanced knowledge sharing accelerates junior artisans’ learning skills quickly, improving artisans’ performance, ensuring sustainability of the skills learned (knowledge retention), encouraging collaboration, building the next generation of leaders and transitioning of experience to mentees emerged as mentorship’s role in developing construction artisans’ skills. Findings show that mentorship mechanisms to develop construction artisan skills face encumbrances. The perceived 32 encumbrances were re-clustered into mentee, mentor and government-related encumbrances. Also, achieving Goal 8 regarding construction artisans may be threatened if these issues are not checked. Thus, the study recommended measures improving construction artisan skills through mentorship mechanisms to achieve Goal 8.

Identifying the major encumbrances facing construction artisan skills improvement through mentorship would be useful to advocate measures to improve construction artisan’s skills to achieve Goal 8.

Globally, prefabrication in housebuilding has evolved as an innovative approach to attain sustainability and affordability. However, the SC, including non-producers and producers, of prefabricated housebuilding projects is still not perceptually aligned, hindering innovation diffusion. This paper investigates the contemporary industry perspective on PHB for conceptualisation, market share and growth, innovation diffusion and the producer's role in the context of New Zealand.

An exploratory qualitative research design was chosen to learn the perceptual stance of the industry. A semi-structured survey was conducted, followed by interviews with selected supply chain participants, who were producers and non-producers and had relevant experience in the PHB industry.

This study reports the common terminologies used by supply chain members, with justification and explanation. Further, the perceived market share and growth of the PHB industry are obtained and compared with subsequent studies to determine the capability and capacity. The perception of the diffusion of PHB by type is reported to portray the overall trend of the industry. In the last, the role of producers as the suppliers of PHB projects is investigated to establish the stakeholder positional criticality.

This study can help researchers and practitioners gain insight into the PHB industry from a multi-dimensional perspective. This study is a potential first step to formalise the policy, programme, strategies and action plan for the uptake of the PHB in the New Zealand.

PHB diffusion in the supply chain perspective, considering multi-dimensional aspects, has not been considered in previous studies as government agencies produce most of the literature. This academic research establishes the theoretical linkage towards PHB diffusion and reports the current status.

It is largely acknowledged that arbitrating the flow of knowledge can help firms strategically leverage tacit and explicit internal knowledge. However, despite the apparent scholarly and managerial acceptance of the criticality of the flow of knowledge between various stakeholders, the academic understanding of knowledge arbitrage remains coarse-grained. There are practically no empirical insights available to unravel the consequences of firms’ knowledge arbitrage choices regarding rewards and risks. This study aims to identify the risks that emerge as firms channel the flow of knowledge from surplus to deficit areas within organizational boundaries. To this end, the authors investigate several subsumed subprocesses in knowledge arbitrage to map the associated risks.

This study used an exploratory qualitative approach to examine the risks that emerge as firms attempt to support knowledge flows within their organizational boundaries. The data were collected through open-ended essays via an online research platform from 45 full-time employees of firms operating in different sectors. The collected data were analyzed inductively through open, axial and selective coding.

The research findings identified three key subprocesses of knowledge arbitrage: knowledge diffusion, knowledge brokering and knowledge absorption. These subprocesses are susceptible to various risks arising the form of channels, champions, sharers and receivers of knowledge flows. In general, the study showed that a firm’s decision regarding knowledge flows, such as structured or random flows, or the presence or absence of designated coordinators to broker the flow carries specific risks for both sharers and receivers. In particular, while the risks of knowledge hiding, misinformation and disinformation manifest in all three subprocesses, low employee engagement, loss of knowledge and information overload also emerged as key risks in any two of the three subprocesses.

This study offers valuable insights by uncovering the hitherto unexplored risks in intrafirm knowledge arbitrage. Given that knowledge is a crucial organizational tool for driving performance, innovation and competitive advantage, understanding the risks associated with intrafirm arbitrated knowledge flows can help firms anticipate and mitigate the associated adverse consequences. The findings make a novel contribution by offering (a) a comprehensive categorization of the risks associated with knowledge arbitrage rooted in processes, people and structures and (b) a macro overview of knowledge arbitrage risks associated with the processes of knowledge diffusion, knowledge brokering and knowledge absorption.

This paper aims to investigate the heterogeneous effects of macroeconomic and financial factors across various distributions of financial deepening in 22 African countries over the past two decades (2000–2019).

The paper uses a recent method of moments quantile regression, which accounts for the often overlooked heterogeneity effects. The analysis focuses on the banking sector, which is predominant in Africa, using a broad range of macroeconomic and financial indicators.

The findings show that gross domestic product per capita positively and significantly impacts financing deepening with an increasing marginal benefit as depth increases. Trade openness positively and substantially affects only high financial deepening. Real interest rate, real exchange rate and inflations negatively and significantly affect financial deepening, especially at higher than lower levels. Financial stability positively and substantially influences financial deepening with an increasing marginal benefit as the depth increases. Bank lending interest rate, bank lending–deposit rate spread, bank concentration and return on equity negatively and substantially impact higher levels of financial deepening than lower levels.

These findings are crucial to policymakers and development partners, as promoting a favourable financial environment and stable macroeconomic policies based on the heterogeneity of financial depths can increase debt financing in Africa.

To the best of the authors’ knowledge, this paper is one of the first attempts to analyse the heterogeneous effects of macroeconomic and financial determinants on varying levels of financial depth in Africa.

The dynamic nature of the built environment and trending smart construction project complexities demand proactive needs tailored towards architecture, engineering and construction (AEC) education. It is a task for the built environment professionals (BEP) to prepare for the future, including the quantity surveying (QS) profession. Studies are scarce in preparing QS education from Nigeria’s stakeholders’ perspective regarding digital technology. Therefore, this paper aims to investigate how to improve QS education by continually updating curriculum digitalisation to meet the construction industry requirements.

Data were sourced from elite virtual interviews across Nigeria. A total of 40 key stakeholders knowledgeable in QS education, advocating a future template for the advancement of QS education in higher institutions, were engaged, and saturation was achieved.

Findings show that improving QS education through continually updating curriculum digitalisation to meet industry requirements cannot be over-emphasised in the 21st-century-built environment industry. The outcomes of the results led to the conclusion that the current QS education curriculum was not meeting the expectations of other BEP stakeholders. Thus, for competitiveness in the future, the QS education curriculum needs to infuse more related-digital technology modules/courses to assist in the sustainability and relevance of the profession within the BEP.

This paper focussed on improving Nigeria’s QS education using digital technologies via a qualitative approach. Future study is needed via a quantitative approach for broader coverage and validation.

The research revealed the need for designing QS programmes to provide for industry demands with emphasis on digital technologies modules/courses. Nigeria’s QS education stakeholders have been stirred up to embrace the curriculum review and make the profession digitalised and relevant within the BEP. The built environment sector is trending towards digitalisation, and the QS programmes cannot afford to be behind.

This research identified the current gap regarding digitalisation of the curriculum. This study will stir QS educational providers and regulators to improve future programmes via digital technologies. It would encourage the use of digital technologies with the right enabling environment. The outcome would mitigate the gap and improve Nigeria’s QS education in the future.
