Abstract
Purpose
This paper aims to investigate homeownership affordability in Nigeria’s urban housing market to establish the determinants of households’ affordability outcomes, and the nature of their impact.
Design/methodology/approach
The cross-sectional survey design was adopted. Semi-structured questionnaire was used to collect data from a sample of households selected through a stratified random technique across Kaduna State, the study area. The binary logistic regression was used to model the probability of homeownership affordability as a function of specified explanatory variables.
Findings
Household income, savings, construction period and education are determinants of homeownership affordability with positive impact. Conversely, household size, cost of land, building cost inflation, current rental housing expenditures, non-housing expenditures and building cost relative to income are determinants of affordability with negative impact.
Practical implications
The findings have the potential to provide a framework for formulation of policy measures to improve access to homeownership.
Social implications
Delayed access to homeownership places pressure on the rented sector with the potential for rental housing affordability problems. It is a deferment of the actualisation of a strong aspiration which is detrimental to individual and family well-being and stability.
Originality/value
The study extends the housing affordability debate to housing markets operating on informal financing where households build rather than buy their homes, an area hitherto not deeply explored. It provides empirical basis for problem-solving on housing affordability and can be a framework for housing policy reforms in Nigeria.

Abstract
Purpose
What are the psychological requirements for increasing fruit and vegetable intake in young people? Psychological theory suggests behaviour modification is driven by ten experiential and behavioural “processes of change”. However, their role in food choice remains unclear. Some of these mechanisms may be nothing more than a proxy for self‐efficacy, a dominant factor in behaviour change. Thus, the aim of this study is to delineate the importance of processes of change (POCs) in fruit and vegetable intake, over and beyond self‐efficacy.
Design/methodology/approach
The study was based on a questionnaire survey assessing POCs and self‐efficacy in relation to change in fruit and vegetable intake. Participants were 150 university undergraduates.
Findings
MANOVA revealed significant differences in both experiential and behavioural processes across stages of behaviour change. These resources were more copious at advanced stages. Controlling for self‐efficacy via MANCOVA negated stage differences in consciousness raising. Overall, though, the contribution of experiential and behavioural processes in fruit and vegetable uptake transcended differentials in self‐efficacy. The unique or direct contribution of consciousness raising requires further investigation.
Research limitations/implications
The findings may not generalise to an older more ethnically diverse population.
Practical implications
Fruits and vegetables interventions may require a mixture of cognitive, self‐evaluative, and behavioural treatments, over and beyond self‐efficacy enhancements.
Originality/value
Although previous studies have demonstrated the importance of POCs in fruit and vegetable intake this study shows that, at least in young adults, these associations largely transcend self‐efficacy, a key driver in behaviour change.

Abstract
The purpose of this chapter is to investigate the adoption and use of building information modelling (BIM) for residential real estate development in Nigeria (using Lagos as a case study), with a view to providing information towards improving BIM uptake, which could enhance sustainable housing delivery in the country. A quantitative research methodology was adopted involving the use of questionnaire survey to collect primary data. The data were obtained from private real estate developers in Lagos State. The self-administered questionnaire was distributed to all the 72 active real estate developers in the study area, and the response rate was 62.5%. The collected data were analysed using statistical tools such as frequency and percentages, mean rating and chi-square. The results revealed a low level of awareness and usage of the transformative and contemporary BIM technology (6D BIM version) by real estate developers. It was established that the 2D and 3D BIM traditional versions were the most utilised across the phases of real estate development process. It was also found that the level of BIM utilisation has a significant relationship with the age and asset base of the real estate developers. The chapter concludes by advocating increase in the asset base and organisational profile of real estate developers to enhance BIM adoption, especially, the 6D BIM, which could facilitate sustainable real estate development.

Abstract
Purpose
The purpose of this paper is to assess the utility of rationalistic constructs for predicting fruit and vegetable intake in children. It was hypothesised that children's gain‐loss evaluations will predict their stage of uptake irrespective of important additional variables.
Design/methodology/approach
Over 200 pupils from a Derbyshire secondary school completed a cross‐sectional questionnaire assessing stages‐of‐change (precontemplation, contemplation, preparation, action, maintenance), gain‐loss considerations, prior consumption, self‐efficacy, and attitude.
Findings
Discriminant function analysis revealed self‐efficacy, attitude, and previous consumption as significant predictors of group membership for both fruit and vegetable intake. Group centroids indicated clear separation of earlier from later stages, and transitional from other stages. Gain‐loss appraisals failed to predict stage membership. Finally, 63.4 and 59.1 per cent of original grouped cases for vegetable and fruit consumption, respectively, were correctly classified. However, classification accuracy varied across stages.
Research limitations/implications
The sample was predominantly Caucasian and from a suburban area. Thus, the generality of these findings to children from other demographics is unclear.
Practical implications
Interventions promoting fruit/vegetable intake in children may lack efficacy if they emphasise possible outcomes (e.g. benefits) associated with eating these foods. Modifying opinions and suggesting easier ways to increase consumption may achieve better results.
Originality/value
Previous research has demonstrated the importance of gain‐loss considerations in adult's stage of fruit/vegetable intake. The current paper extends this literature to children; it appears rationalistic constructs play a negligible role in children when considered within the context of other variables.

Abstract
Purpose
In this paper, the philosophy of John Rawls, known as “Justice as Fairness,” is discussed. This philosophy examines the responsibilities social actors hold toward their societal organizations. From an Islamic perspective, justice is pivotal in safeguarding collective interests, aligning with Rawls' conviction that just societies nurture happiness and foster well-being across various life aspects. To achieve customer welfare, our viewpoint underscores the importance of justice in reflecting on consumer well-being from both Rawls’ theory and Islamic perspectives.
Design/methodology/approach
We adopt a conceptual approach where secular views of Rawls’ “Theory of Justice” are merged with the Islamic view, resulting in novel insights regarding the hermeneutics involved in the notion of justice and the preservation of consumer well-being.
Findings
Our analysis reveals that John Rawls' “A Theory of Justice” aligns with the Islamic perspective in several respects yet diverges in others, notably in the concepts of pre-creation consciousness and divine guidance. These distinctions are emphasized in our paper.
Originality/value
Our paper presents a perspective on justice founded on the concepts of the “Original Position” and the “Veil of Ignorance.” The commentary explores consumer well-being by integrating Rawls' principles with an analysis that elucidates the role justice plays in enhancing societal welfare.

Abstract
This study examines the improvement of rice production in Nigeria through the government’s policy of the Anchor Borrowers’ Programme (ABP). Rationalized by the production theory, the study utilizes quantitative methods such as surveys. The study investigates the influence of ABP on rice production, with particular emphasis on the experiences of smallholder rice farmers in Ebonyi State, Nigeria. The study employed a cross-sectional survey research approach, and the target population comprised smallholder rice farmers in the state who have benefitted from ABP. The study obtained a representative sample of 400 respondents through stratified random sampling. The study adopts the administration of a structured questionnaire with rice farmers in Ebonyi State, Nigeria, as the primary data collection method. Regression was used to test the hypotheses in SPSS version 23. From the findings, the study reveals the need for the ABP, banks and other lending agencies/programmes to train farmers. It shows that modern farming contributes to rice production in Ebonyi State.

Abstract
Purpose
From the perspective of plant and machinery valuation, this paper aims to assess the factors that constrain accuracy in plant and machinery valuation in the Nigerian context.
Design/methodology/approach
This paper is based on the technical, economic and market infrastructure affecting machinery and equipment valuation in Nigeria and surveyed 150 practicing firms in Lagos to elicit from them what they believe are the major constraints to valuation accuracy.
Findings
The findings reveal that, due to lack of specialization in machinery and equipment valuation, very few valuers have sufficient knowledge content to engage in the exercise. Four significant factors are established to be contributing most to valuation inaccuracy.
Originality/value
This study is the first on inaccuracy in machinery and equipment valuation, and consequently highlights the need to equip Nigerian valuers to face the challenges of the expertise required in this specialized area of valuation.

Abstract
Purpose
This study examined factors influencing the organisational capabilities of the public sector for building information modelling (BIM) implementation in construction projects with a view to enhancing the performance of public sector projects.
Design/methodology/approach
The study adopted a quantitative descriptive analysis that was based on primary data. In total, 198 valid questionnaires obtained from construction professionals within the public sector provided primary quantitative data for the assessment. The respondents provided the responses on the factors which were identified through an in-depth synthesis of literature relating to organisational capabilities of the public sector. Data collected were analysed using descriptive and inferential statistics.
Findings
The findings established that the potential of the public sector to deploy BIM in construction projects is greatly influenced by varying degree of organisational capability attributes with bureaucratic culture (mean score, MS = 3.37), structural complexity (MS = 3.17), lack of skilled and trained staff (MS = 3.12), personnel stability (MS = 3.11), staff cooperation (MS = 3.09) and political constraint (MS = 3.07) ranked highest. Through factor analysis, these and other highly influential factors were grouped into eight components, namely management-related, policy-related, technical-related, attitude-related, work structure-related, work ethic-related, decision-related and feedback-related factors. This grouping reflects the various components of organisational capability attributes which the public sector needs to efficiently develop to benefit from project management paradigm introduced by BIM.
Practical implications
This study provided information for improving specific capability attributes with respect to human and technical resources as well as other soft infrastructure to support BIM implementation on building projects by the public sector client. The study also serves as a guide for understanding BIM implementation by the public sector in similar socio-political and economic contexts.
Originality/value
This assessment indicates various degrees by which the organisational attributes of public sector have influenced the attributes' capability to implement BIM on construction projects. Thus, findings provide information on areas of improvement for better implementation of BIM by the public sector in project delivery.

Abstract
Purpose
The Nigerian construction industry, like in most emerging economies has been slow with technological advances such as building information modeling (BIM). More so, the application of BIM among Nigerian practitioners is rather limited to architects’ usage for schematic design and presentation of drawings. The purpose of this study is to enhance BIM’s uptake, this study explores the drivers for the implementation of BIM within the Nigerian construction industry.
Design/methodology/approach
An interpretivist epistemological design was adapted to extensively manually review and search the literature on BIM implementation drivers. Based on 14 drivers for BIM implementation drivers identified, a survey questionnaire was used to collect data from the Nigerian construction practitioners. The data obtained is then subjected to descriptive, inferential statistics and multivariate techniques such as factor analysis.
Findings
The study, through factor analysis, categorized the 14 drivers to BIM implementation into four principal factors. The factors are construction related-drivers; process digitalization and economic-related drivers; sustainability and efficiency-related drivers; and visualization and productivity-related drivers.
Practical implications
To effectively adopt BIM in the construction industry, it is necessary to identify the BIM implementing drivers, which can act as catalysts of change and, thus leading to sustained adoption of BIM. Therefore, the identified drivers and categorization of principal factors could provide managerial implications for better execution and adoption of BIM, as well as the creation of the required change for the BIM implementation.
Originality/value
The research provides insights into the implementation drivers of BIM in lesser studies in a developing country such as Nigeria. The study further contributes to this research sphere by using factor analysis to customize and contextualize the drivers that were previously identified.

Abstract
Purpose
Building information modelling (BIM) adoption is vital to the productivity and competitive nature of the construction sector. However, BIM adoptions have not been generally embraced by many architecture, engineering and construction (AEC) firms, particularly in developing countries. Moreover, studies that investigate the important drivers to BIM adoptions among construction professionals through quantitative approach are limited. The purpose of this study is to address the aforementioned gap.
Design/methodology/approach
This study involves a literature review, a pilot study and a questionnaire survey. The primary data were carried out using structured questionnaires distributed to four different BIM adopter AEC firms. These comprised architectural firms, facility management firms, quantity surveying firms and structural engineering firms in Lagos, Nigeria. Data obtained were analysed using mean score, standard deviation, Kruskal–Wallis test and factor analysis.
Findings
The study identified 23 drivers to BIM adoption, and the relative importance of the identified drivers was gauged from each selected BIM adopter AEC firm category. The result of the Kruskal–Wallis test showed that there is no statistically significant difference in the perceptions of the four selected AEC firms in the mean ranking of the identified 23 drivers to BIM adoption. The findings from factor analysis categorized the identified drivers into two major factors to include cost and time savings, improved communication, and BIM awareness and government supports.
Practical implications
The study empirically identifies important drivers to BIM adoption that will be useful for construction stakeholders to formulate strategies to adopt the full implementation of BIM in the AEC firms of Nigeria and other developing countries. Also, this study is important as it identifies, analyses and compares the drivers to BIM adoptions from four different AEC firms, thereby providing robust and more reliable findings.
Originality/value
The study findings will provide information to policymakers and construction stakeholders to make policy recommendations that are capable of positively influencing the widespread adoption of BIM in AEC firms in particular and the construction industry at large. This study is important because the studies that comparatively and empirically analyzed BIM drivers in AEC firms are rare, particularly in developing countries. Hence, this study could be used to benchmark future studies in developing countries.
