Abstract
Purpose
The purpose of this paper is to evaluate the adoption of quantitative risk analysis techniques (QRAT) on construction projects in Nigeria with a view to providing better understanding on the state of these techniques.
Design/methodology/approach
Questionnaire survey was employed in gathering data for the study. The paper assessed the level of knowledge, awareness, utilization, success and the factors influencing the adoption of QRAT. The primary data employed were obtained by using multiple-choice questionnaire administered to the selected large construction companies in Nigeria.
Findings
The result of the study revealed a low level adoption of QRAT, and this inhibits Nigerian construction industry from taking full advantage inherent in QRAT. Also, it prevents the analysis of risks peculiar to construction projects. Furthermore, inadequate training and record keeping on risk management were identified as significant factors affecting the adoption/utilization of QRAT on construction projects.
Research limitations/implications
Multiple-choice questionnaires administered to the respondents (architects, quantity surveyors, builders, structural engineers, civil engineers, and mechanical and electrical engineers) were limited to the selected large construction companies in the category D of the Nigerian Federal Tender Board.
Originality/value
This empirical inquiry provided strong evidence on the state of QRAT of construction projects in Nigeria. The findings revealed insightful perspectives to understand construction project QRAT in its entirety. For stakeholders, understanding and addressing the complexity help to improve project planning and implementation.

Abstract
Purpose
The purpose of this paper is to evaluate the adoption of qualitative risk analysis techniques (QRAT) on construction projects in Nigeria with the aim of providing better understanding on the state of these techniques.
Design/methodology/approach
A questionnaire survey and an in‐depth interview were employed in gathering data for the study. The paper assessed the level of knowledge, awareness, utilization success and the factors affecting the utilization of qualitative risk analysis techniques. The primary data employed were obtained by using a multiple‐choice questionnaire administered to the selected large construction firms in Nigeria.
Findings
The result of the study revealed a low level adoption of QRAT, thus preventing the Nigerian construction industry from taking full advantage of QRAT in the analysis of risks inherent in construction projects. Also checklists, flowchart and assumption analysis were the commonly used QRAT in the study area. Furthermore, inadequate training and record keeping on risk management contributed largely to the factors affecting the utilization of QRAT on projects.
Research limitations/implications
Multiple‐choice questionnaires administered to the respondents (architects, quantity surveyors, builders, structural engineers, civil engineers, mechanical and electrical engineers) were limited to the selected large construction firms in the category D of the Nigerian Federal Tender Board.
Practical implications
The construction sector has not taken full advantage of QRAT in the analysis of risks inherent in construction projects. This has been responsible for cost and time overruns usually recorded. Analysing risks will help the stakeholders in assessing degrees of project complexity and better manage the potential risks that might be induced to different levels of construction projects in Nigeria in order to achieve hitch free construction project delivery.
Originality/value
This empirical inquiry provides strong evidence on the state of qualitative risk analysis techniques of construction projects in Nigeria. The findings provide insightful perspectives to understand construction project QRAT in its entirety. For stakeholders, understanding and addressing the complexity help to improve project planning and implementation.

Abstract
The challenges confronting the Nigerian construction industry which led to the adoption of supply chain management (SCM) practice were evaluated in this chapter. It was discovered that the Nigerian construction industry is confronted with fragmentation and poor information management. The stakeholders within the Nigerian construction industry proposed the adoption of SCM to overcome the fragmentation and other shenanigans facing the industry. This chapter revealed that construction supply chain (CSC) practices within the Nigerian construction industry focus on waste elimination by adopting the lean concept. The focus on the lean concept could be attributed to the numerous research related to lean or the enormous waste emanating from the Nigerian construction industry. Regardless of the emphasis on lean, the Nigerian CSC is still confronted with fragmentation and heavy waste generation. Thus, this chapter proposed the adoption of principles and technologies driven by the fourth industrial revolution (4IR) is a paradigm shift for the management of CSC in the country. It was discovered in this chapter that Nigerian construction supply stakeholders had not embraced the technologies and principles of the 4IR. The failure to adopt the technologies driven by the 4IR is attributed to the absence of a CSC model that depicts the management of CSC in alignment with the 4IR. This chapter called for developing a SCM model for the Nigerian construction industry in tandem with the principles and technologies of the 4IR.

Abstract
Purpose
The non-performance of construction projects in meeting the set objectives has continued to draw researchers worldwide. Despite this, little attention is accorded to public tertiary education building projects in Nigeria. Therefore, on this background, this study aims to assess the perceptions of stakeholders on the level of occurrence of risk factors in the public tertiary education building projects (TEBP) to enhance the performance of these projects.
Design/methodology/approach
The study adopted a quantitative method of data collection via a questionnaire survey. In total, 452 questionnaires were administered to the respondents comprising client representatives, consultants (quantity surveyors, architects, services and structural engineers and builders) and the contractor. The respondents were involved in the conception and execution of TEBP across five public tertiary education institutions in Ondo State, Nigeria. Of 452 questionnaires, 279 were retrieved and found suitable for analysis, indicating a 61.73% response rate. The reliability analysis for the research instrument was 0.965 via the Cronbach α test, indicating the high reliability of the instrument used for the data collection. Moreover, the clusters of risk factors also had reliability values that ranged between 0.719 and 0.875.
Findings
The study found inflation, delayed payments in contracts, high competition bids, delay in work progress and occurrence of variations are the most frequently occurring risk factors in public TEBP. By contrast, difficulty to access the site, environmental factors and pollution were found to be low-weighted risks with the least likelihood of occurrence. The results of this study indicated the existence of significant differences in some of the risk factors in terms of the level of risk occurrence in TEBP. The risk factors were eventually clustered into eight major groups for TEBP. The post hoc comparisons using the least significant difference test also indicated differences between the contractors and consultants in the ranking of risks occurrence in TEBP, but no significant differences between clients/contractors and clients/consultants.
Research limitations/implications
The findings in this study are limited to the public TEBP procured via competitive tendering; therefore, the results might not be applicable when other procurement methods are being considered. Besides, the study classified the project participants based on organizations and not on the different ownership status of the projects, such as federal or state government-owned TEBP. However, the literature shows that likelihood of risk occurrence could vary due to the degree of project ownership.
Practical implications
The information provided with respect to the most frequently occurring risk factors would enhance the performance of public TEBP.
Originality/value
This study contributes to the existing body of knowledge on the subject within a previously unexplored context where insights were provided on the most frequently occurring risk factors on the public TEBP.

Abstract
Purpose
Insufficient time allocation for the bidding period occurs, causing drawbacks to both parties, the client and the bidder. Hence, this study aims to evaluate the time allocated for preparing a bid proposal as per the National Competitive Bidding (NCB) in the Sri Lankan context.
Design/methodology/approach
The study has adopted a mixed method approach and expert interviews and document review to detect, analyse and validate the issues, and solutions based on NCB along with the adequacy of the allocated bidding period used as main data collection tools. Both qualitative and quantitative data were analysed through manual content analysis and inferential analysis respectively.
Findings
Overall, 24 local issues with the existing competitive bidding process and solutions for each were identified. Among the 24 local issues, it was unanimously agreed by all interviewees that three specific issues require attention and improvement. These issues are related to the standard and incompleteness of bidding documents, inaccurate BOQ quantities measured by the consultant or the main contractor, and the excessive number of bidding document amendments by the consultant. It was revealed that a maximum of 42 calendar days (6 weeks) is sufficient for the bidding process while a minimum of 21 calendar days (3 weeks) is insufficient.
Originality/value
The findings of this study would be recommended that Information and Communication Technology Agency (ICTA) understand the necessity of revising the NCB reference to the time allocated for the preparation of bids. By recognising the importance of sufficient time allocation for bid preparation, this research serves as a practical guide for authorities involved in policy formulation, aiding them in implementing revisions that align with the dynamic requirements of bidding procedures.

Abstract
Purpose
People with intellectual disabilities (ID) can be vulnerable to developing mental health problems. It has been found that participating in regular exercise can help to improve emotional well-being, both in typically developing people and those with ID. The purpose of this paper is to investigate the experiences of community clients with ID who have engaged in a football training programme, and the perceived impacts on attitudes, mood and behaviour.
Design/methodology/approach
Interviews with seven patients from generic or forensic community ID services were conducted. The transcripts were analysed using interpretative phenomenological analysis.
Findings
Two master themes were identified from the interviews, “Striving” and “Togetherness”.
Originality/value
The most important factors related to taking part in the football programme were the social, emotional and personal growth associated with being part of a team and general enjoyment of being part of something. Although aspects of football knowledge and physical fitness were still evident, their impact seemed to be less significant. The experience of football was overwhelmingly positive.

Abstract
Purpose
One of the targets of sustainable development goal (SDG) 2030 is to reduce maternal mortality ratio to 70 per 100,000 live births and ensure pregnant women attend at least four antenatal visits. In urban Pakistan, it is expected that more women utilize antenatal care (ANC) because urban areas have more resources, higher education and wealthier people. Despite these facilities, the lack of utilization of antenatal care among pregnant women is abysmal—the latest estimate by Pakistan Demographic and Health Survey (PDHS) places the figure at 63%. Therefore, the paper attempts to identify the factors that affect the utilization of ANC in urban areas by using the PDHS 2017–2018.
Design/methodology/approach
The study used cross-tabs to determine the socioeconomic characteristics of women, and used the marginal effects from the probit model to evaluate the significance and relationship between socioeconomic determinants and antenatal visits. Finally, the study used Adam Wagstaff's decomposition analysis to identify the magnitude and main determinants of inequality.
Findings
The marginal effects show that socioeconomic variables such as education, province of residence, birth of a first child, age, education and consulting a doctor predicted the probability of 4+ antenatal visits. The decomposition analysis shows that women who consulted a doctor, belonged to non-poor class, were more educated and older contributed significantly to the inequality of antenatal care utilization in urban areas.
Practical implications
The study calls for increasing the number of doctors, promoting education, increasing awareness related to pregnancy complications and reducing wealth inequality. Moreover, the study also calls for increasing global intervention by implementing programs similar to ending preventable maternal mortality (EPPM) to increase antenatal coverage.
Originality/value
The distinctiveness of the study can be found in the fact that no study has been conducted that analyses the inequality related to the usage of ANC in urban areas of Pakistan.

Abstract
Purpose
Delivering vaccines to the children who need them requires a supply chain that is efficient and effective. In most of the developing countries, however, the unknown and unresolved supply chain issues are causing inefficiencies in distributing vaccines. There is, therefore, a great need in such countries to recognize the issues that cause delays in vaccine delivery. With this purpose, the present study aims to identify and analyze the key issues in the supply chain of basic vaccines required to immunize children in developing countries.
Design/methodology/approach
Based on a field survey of three states of India, in-depth review of relevant literature and experts’ opinions, 25 key issues were recognized as factors of the vaccine supply chain (VSC) and categorized into five main domains. Using integrated interpretive structural modeling and fuzzy analytic network process approaches, the issues have been prioritized to determine their relative importance in the VSC. In addition, a sensitivity analysis has been performed to investigate the priority stability of the issues.
Findings
The results of the analysis show that among the five domains of VSC issues, the economic domain with a weight of 0.4262 is the most important domain, followed by the management (0.2672), operational (0.2222), environmental (0.0532) and social (0.0312).
Research limitations/implications
This study focuses on the prioritization of VSC issues; therefore, the results of the present study can provide direction to the decision-makers of immunization programs of developing countries in driving their efforts and resources on eliminating the most important obstacles to design successful vaccination programs.
Originality/value
To the authors’ knowledge, this paper is first to provide a direction to the decision-makers in identifying and managing important issues through the use of an analytical approach.

Abstract
Purpose
This study aims to explore the link between prevalent risk factors for early childhood diarrhea, including hygiene, feeding, weaning practices and maternal education and the occurrence and severity of early childhood diarrhea in Saudi Arabia.
Design/methodology/approach
A case-control study was conducted, involving 98 mothers from the Eastern Region of Saudi Arabia (51 cases and 47 controls). Data were collected from both hospital and community sources. The collected data were statistically analyzed and depicted using descriptive statistics and frequency tables.
Findings
Demographic data revealed that 60% of mothers were housewives, 75% had normal deliveries and all babies were full term. In the study cohort, 44% of children aged one to two years. Four domains were compared: diarrheal management, hygiene, weaning and feeding practices. Diarrheal management was suboptimal in some cases: 29% increased fluid intake, 10% maintained adequate food intake, 50% sought medical advice, 58% were familiar with oral rehydration solutions and only 37% used them. Hygiene practices were deficient, with 35% using wipes or sanitizers, 64% handwashing before feeding and 52% adhering to the recommended 10-s duration. Controls exhibited better hygiene practices. Weaning practices were generally similar, with no significant differences between the two groups.
Originality/value
To the best of the authors’ knowledge, this is the first study to collectively report on the risk factors linked to early childhood diarrhea in Saudi Arabia. This study yields significant insights, highlighting the crucial role of managing diarrhea, educating mothers and implementing proper household practices in impacting the occurrence and severity of this perilous ailment.
