The purpose of this paper is to determine the prevalence of general and abdominal obesity among adolescents attending independent schools in Qatar.

A school-based cross-sectional study was conducted in November-December 2013 in 23 secondary schools. A total of 1,161 students aged 14 to 19 year olds were randomly selected using a multistage stratified cluster random sampling technique. Body weight, height and waist circumference (WC) were measured using standard protocol. The International Obesity Task Force (IOTF) age- and sex-specific body mass index (BMI) reference were used to define overweight and obesity. Abdominal obesity (AO) was defined by waist to height ratio (WHtR ≥ 0.5) and by sex- and age-specific WC cut-off values.

The prevalence of overweight and obesity among the study population was 20.6 and 20.7%, respectively. The highest rate of overweight and obesity was observed among boys, and the youngest age group. The rate of obesity defined by either WC/or WHtR was higher than that assessed by BMI. The prevalence of AO assessed by WC and WHtR was 48.8 and 46.9%, respectively. The rate of AO was significantly higher (p < 0.05) among boys compared to girls for both assessment criteria. The proportion of adolescents with AO (WHtR ≥ 0.5) according to BMI was 17.3%, 80.8% and 97.1% for adolescents with normal, overweight and obesity had AO, respectively. Being male was significantly associated with higher odds of having both general obesity and AO.

The study revealed a high prevalence of general and abdominal obesity in adolescents in Qatar. Waist measures appear to be an important indicator in identifying adolescents at risk and should be included as screening tools for cardiometabolic risk.

This case captures the experience of the newly hired investigation officer (IO) at the SECP, who crafts a front running case focused on the ethical transgressions by equity trader and KATS operator, at a famous brokerage house named Mir Ali Chaudhary Securities (MAC) Securities and three traders at DICE in Pakistan. The case outlines the whole series of investigation event that took place, from the IO identifying the smoke to all the pieces of puzzle together to form collectively evidence of front running. The case outlines and probes students to think at each stage of investigation as to how to answer the general claims that insider trading should be legalized. All these questions are viewed from the perspective of Pakistan’s regulatory environment.

The authors use a descriptive case study methodology approach.

The investigation trial held Sidney and Aslam guilty, sentencing them to imprisonment and making them pay fine to the Securities Exchange Commission of Pakistan (SECP) worth Rs 5m and Rs 1m, respectively. Likewise, the three equity traders at DICE were sentenced to imprisonment and charged a fine of Rs. 1m each.

On March 21, 2018, Mr Sidney, the equity trader, Mr Aslam, a KATS operator at MAC Securities and three equity traders at DICE Securities (Pvt.) Ltd were convicted under Securities Act (2015) and Court of law. Sidney and Aslam were alleged of tipping off advance confidential information of their clients’ order to the three equity traders at DICE, whereas the three traders at DICE were alleged of trading shares based on the tipped information in their trading account before the MAC clients’ orders were filled.

Cost overruns are an inevitable issue in design and build (D&B) projects. In D&B projects, causes for cost overruns can be managed by adopting appropriate building information modelling (BIM) functions. Because there is a research gap in synergy between the use of BIM for mitigating cost overruns in D&B projects, this study aims to evaluate the adaptability of BIM to manage cost overrun issues in them.

Research objectives were attained through a quantitative research approach adopting the Delphi technique, which consists of three rounds of a questionnaire survey. Through statistical tools, the collected data were analysed.

This research revealed the ten most crucial causes for cost overruns in D&B projects, where continuous changes in designs and drawings are the top causes. Change and revision management and interoperability are the most crucial BIM functions to address the aforementioned cause. Subsequently, 16 enablers, 26 barriers and 19 strategies to implement BIM to manage the identified significant causes of cost overruns were overviewed.

This study addresses the literature gap pertaining to the cost overrun in D&B projects and the application of BIM by studying the causes for cost overrun, suggesting BIM functions to mitigate the above cause. Moreover, this study assessed the probable barriers and enablers for BIM adoption in construction projects from D&B perspective.

Construction is a risky industry. Therefore, organizations are seeking ways towards improving their safety performance. Among these, the integration of technology into health and safety leads to enhanced safety performance. Considering the benefits observed in using technology in safety, this study aims to explore digital technologies' use and potential benefits in construction health and safety.

An extensive bibliometrics analysis was conducted to reveal which technologies are at the forefront of others and how these technologies are used in safety operations. The study used two different databases, Web of Science (WoS) and Scopus, to scan the literature in a systemic way.

The systemic analysis of several studies showed that the digital technologies use in construction are still a niche theme and need more assessment. The study provided that sensors and wireless technology are of utmost importance in terms of construction safety. Moreover, the study revealed that artificial intelligence, machine learning, building information modeling (BIM), sensors and wireless technologies are trending technologies compared to unmanned aerial vehicles, serious games and the Internet of things. On the other hand, the study provided that the technologies are even more effective with integrated use like in the case of BIM and sensors or unmanned aerial vehicles. It was observed that the use of these technologies varies with respect to studies conducted in different countries. The study further revealed that the studies conducted on this topic are mostly published in some selected journals and international collaboration efforts in terms of researching the topic have been observed.

This study provides an extensive analysis of WoS and Scopus databases and an in-depth review of the use of digital technologies in construction safety. The review consists of the most recent studies showing the benefits of using such technologies and showing the usage on a systemic level from which both scientists and practitioners can benefit to devise new strategies in technology usage.

The impact of building information modeling (BIM) on various aspects of project management has attracted much attention in the past decade. However, previous studies have focused on a particular facet of project management (e.g., safety, quality, facility management) and within identified target journals. Despite numerous existing studies, there is limited research on the mainstream research topics, gaps and future research directions on BIM in project management. This study aims to conduct a bibliometric and science mapping review of published articles on BIM in project management and to identify mainstream research topics, research gaps and future research directions in this domain.

A science mapping approach consisting of bibliometric search, scientometric analysis and qualitative discussion was used to analyze 521 journal articles that were retrieved from the Scopus database and related to BIM in project management. In the scientometric analysis, keyword co-occurrence analysis and document analysis were performed. This was followed by a qualitative discussion that seeks to propose a framework summarizing the interconnection between the mainstream research topics, research gaps and future research directions.

Six mainstream research topics were found including (1) BIM-enabled advanced digital technologies, (2) BIM-based reinforcement and enhancement, (3) BIM and project composition, (4) BIM project elements and attributes, (5) BIM-based collaboration and communication and (6) BIM-based information and data. Moreover, this study discussed six research gaps, namely, (1) integration of BIM and other digital technologies, (2) future maturity of BIM applications in project management, (3) application of BIM in project components and processes, (4) role of BIM application in project elements and attributes, (5) impact of collaboration and communication in BIM application and (6) stability of information and data interaction. Furthermore, future research directions were discussed.

The findings and proposed framework contribute to providing a deeper understanding to researchers, policymakers and practitioners in the development of related research and practice in the domain of BIM in project management, thus, promoting digital transformation in project management. Overall, it adds to the global knowledge domain in BIM and promotes the need for digital and data integration, BIM maturity and BIM collaboration.

The purpose of this study is to critically analyze the Financial Compensation Funds being accumulated by Islamic Banks of Bangladesh in credit-based transactions. In this connection, due to the evolved liquidity crisis amidst the COVID-19, industry opinions are observed that suggest including the compensations or the donation funds directly into the bank's income account. But the Sharīʿah does not permit it. Such alternative proposals of using compensation or donation fund during crises are scrutinized under Sharīʿah principles to come to a logical conclusion.

The approach followed in the study is textual and discourse analysis through descriptions of ideal Sharīʿah-compliant methods for handling late payment of credit and comparison with the industry practices.

It is observed that there are conceptual gaps in the industry as is reflected in the Islamic Banking Guideline of Bangladesh. The funds collected from the debtor due to late payment are named as compensation (Ta‘wīḍ) whereas the nature of the transaction is a donation (Tabarru'). The misconception can lead to various Sharīʿah non-compliant activities later with the funds. The proposals brought out in the industry to use such compensation/donation funds during a crisis are a consequence of this. The proposals of using such funds for banks' purposes in any situation are not supported by Sharīʿah principles and are against the Islamic banking philosophy.

The study is very relevant to the current crisis of COVID-19 in the domestic Islamic Banking Industry and also instrumental for the future guidance to stick to the Sharīʿah principles in managing compensation or donation funds by the Islamic Banks.

This study evaluates the knowledge structure of building information modeling (BIM) in green buildings. Buildings are one of the main contributors to carbon emissions, and implementing BIM in green buildings is seen as an indispensable approach to mitigate environmental and climate change issues.

Through a bibliometric analysis, 297 publications retrieved from the Web of Science (WoS) were analyzed to explore their intellectual structure.

Bibliographic coupling analysis produced four clusters on current and emerging trends, while co-word analysis produced four clusters on future BIM and green building trends. Current and emerging trends revolve around BIM adoption in green and existing buildings, life cycle analysis (LCA) and sustainable rating tools. Future trends related to BIM and performance analysis and optimization, the BIM framework for green building design and construction, overcoming barriers and maximizing benefits in BIM adoption.

The implications of this study are relevant to all BIM and green building stakeholders, including developers, engineers, architects, occupants, tenants and the whole community.

This study examines the crucial integration of BIM and green building within the more extensive construction and building field scope.

This study aims at introducing a claim management model based on building information modeling (BIM) for claims that can be visualized in BIM models.

Based on the results of a questionnaire survey, 10 claims were identified as claims that can be visualized in BIM models (named hard claims in this study). Then, a BIM-based claim management model was developed and used in a case study.

A BIM-based claim management model is represented. The claim management process through this model consists of four steps: (1) extracting project information, identifying conditions prone to claim and storing them into a relational database, (2) automatically connecting the database to building information model, (3) simulation of the claims in building information model and (4) final calculations and report.

The proposed model can provide benefits to parties involved in a claim, such as early identification of potential claims, large space for data storage, facilitated claim management processes, information consistency and improved collaboration.

There are a few studies on providing solutions to claim management based on BIM process. Hence, the original contribution of this paper is the attempt to set a link between BIM and claim management processes.

The aim of this research is to determine the impact of a learning organisation (LO) on developing quality improvement practices (QIPs) and to propose knowledge-sharing (KS) as a moderator which is anticipated to support the beneficial effect of a LO on QIP. A further objective is to establish whether training provision raises the abilities of healthcare organisations (HCOs) to attain greater standards of QIP via a LO and KS.

A total of 240 responses, obtained from employees working at private HCOs in Jordan, comprised the valid dataset. Structural equation modeling (SEM) was utilised for data analysis. Multigroup analysis (MGA) was performed to compare the impact of workers who had or had not undergone training.

The findings indicated that QIP was significantly enhanced by LO. HCOs with the objective of converting a KS-moderated LO could attain improved QIP standards, but within the surveyed establishments, this effect was only appreciated at modest degrees. By performing MGA, no variations were identified in the impact of workers.

Managers should place more emphasis on training and learning within HCOs. However, respondents did indicate that their establishments had notable degrees of KS, suggesting a potential strength that could be used positively by the managerial hierarchy.

This study encompasses an original contribution to contemporary scholarship in the field of knowledge management and quality through its examination of the moderating effect of KS on LO and QIP.

Design cost overrun is one of the prominent factor that can impact the sustainable delivery of the project. It can be encountered due to a lack of information flow, design variation, etc. thereby impacting the project budget, waste generation and schedule. An overarching impact of this is witnessed in the sustainability dimensions of the project, mainly in terms of economic and environmental aspects. This work, therefore, aims to assess the implications of a technological process, in the form of building information modelling (BIM), that can smoothen the design process and mitigate the risks, thus impacting the sustainability of the project holistically.

The identified design risks in construction projects from the literature were initially analysed using a fuzzy inference system (FIS). This was followed by the focus group discussion with the project experts to understand the role of BIM in mitigating the project risks and, in turn, fulfilling the sustainability dimensions.

The FIS-based risk assessment found seven risks under the intolerable category for which the BIM functionalities associated with the common data environment (CDE), data storage and exchange and improved project visualization were studied as mitigation approaches. The obtained benefits were then subsequently corroborated with the achievement of three sustainability dimensions.

The conducted study strengthens the argument for the adoption of technological tools in the construction industry as they can serve multifaceted advantages. This has been shown through the use of BIM in risk mitigation, which inherently impacts project sustainability holistically.

The impact of BIM on all three dimensions of sustainability, i.e. social, economic and environmental, through its use in the mitigation of critical risks was one of the important findings. It presented a different picture as opposed to other studies that have mainly been dominated by the use of BIM to achieve environmental sustainability.
