Abstract
Purpose
The purpose of this paper is to evaluate mentoring behaviours in a public medical school in Malaysia and examine factors associated with those mentoring behaviours. The study is important because effective mentoring promotes the personal and professional growth of mentees.
Design/methodology/approach
A cross-sectional study was conducted with a population of 632 medical students. The authors used the Mentor Behaviour Scale (MBS) to measure four domains of mentoring behaviour: mentoring relationship structure, engagement, autonomy support and competency support. The authors evaluated the scoring of these domains as high, moderate or low scores.
Findings
A total of 508 (80.4 per cent) medical students in Years 2–5 participated in this study. Mentoring relationship structure, engagement and competency support were perceived as moderate scores, whereas autonomy support was perceived as a low score. Students in the early phases of study had better attitudes regarding mentoring behaviours. More frequent meetings and longer duration of meetings were significantly associated with better attitudes towards mentoring behaviour.
Originality/value
This paper evaluates contemporary mentoring behaviours in a Malaysian public medical school and contributes to non-western literature on mentoring. These behaviours were reflected in the four domains of the theory-based MBS.

Abstract
The provision of open spaces within a residential development is often seen as unimportant. The Malaysian Government targeted to provide 2 hectares of open space per 1000 population to be achieved as a developed nation status by the year 2020. This vision can be seen as the Government attempt to ensure the sustainability of open spaces in Malaysia. The Federal Department of Town and Country Planning, Peninsular Malaysia (FDTCP) has produced a planning standard guideline to supervise the implementation of the open space policy in Malaysia. According to FDTCP; until December 2009, Malaysia has achieved a percentage of 1.19 hectares of open space per 1000 population. Achieving the standard requires commitment of local authorities to implement the open space policy. However, the adoption of open spaces policy differs among local authorities, from a simplistic general approach of land ratio techniques to an ergonomics method. The paper examines the local allocation practices using 5 different approaches and it argues that implementation of open space by local planning practices requires the knowledge of and understanding by planning profession towards a long term sustainable green objectives.

Abstract
Purpose
The purpose of this paper is to perform a computational fluid dynamics (CFD) simulation that is able to reveal what is happening for the shock wave generated by high speed flow test facility and to develop deeper understanding of all parameters which affect the shock wave velocity profile and pressure and temperature histories inside the facility.
Design/methodology/approach
Two dimensional time accurate Euler solver for shock tube applications was developed to simulate the flow process inside the shock tube. To ensure the ability of the CFD code to capture shocks, rarefaction waves and contact discontinuity and to produce the correct pressure, temperature, density and speed profiles, the code has been validated using two verification approaches. First, the code results have been compared to the Sod's tube problem (exact solution). Second, the code solution is compared with selected experimental measurements for a certain diaphragm pressure ratio.
Findings
Results presented in this paper show that after diaphragm rapture and when the shock did not reflect yet, the flow is symmetry and uniform in y‐direction. As the shock wave reflects from the tube end it will move to the left and interact with the discontinuity surface and the flow no longer symmetry. Results also show that two‐dimensional modeling of the high speed flow test facility is an effective way to obtain facility performance data. Although this paper focused on UNITEN's facility, the CFD code is generic and may be applied to other facilities. The present code showed good capability to provide the x‐t diagram successfully. From this diagram one can determine the useful duration (for this case it is about 10 ms), which is quite comparable compared to other facilities. It can be concluded, based on the agreement with the analytical results, that the numerical formulation for the inviscid part of the solver is valid.
Originality/value
This paper performs a CFD simulation that is able to reveal the shock wave behavior at high speed flow test facility.

This study aims to find out the problems of family Takaful (Islamic Life Insurance) operations in Bangladesh and proposes strategies to overcome the problems.
Abstract
Purpose
This study aims to find out the problems of family Takaful (Islamic Life Insurance) operations in Bangladesh and proposes strategies to overcome the problems.
Design/methodology/approach
Qualitative data were collected through interviews with 32 respondents from two family Takaful operators in Dhaka, Bangladesh.
Findings
The study finds a number of problems of family Takaful which relate to the government, Takaful company and the Shariah board. Lack of governing guidelines for Takaful companies in Bangladesh is causing numerous operational problems of family Takaful. To overcome these obstacles, the government should propose separate Act for Takaful. This requires support from the stakeholders along with Islamic scholars in the country.
Practical implications
It is anticipated that the findings and suggestions of the study will assist the policymakers in improving the situation of family Takaful companies particularly in Bangladesh.
Social implications
If the proposed suggestions are implemented in Takaful companies, the problems facing Takaful will likely be solved and more people will take part in Takaful. This would contribute to developing the country economically, raise Islamic values and foster peace and harmony in the society.
Originality/value
Mainly, this study is based on the primary research that has been conducted in family Takaful companies in Bangladesh.

Abstract
Increasing humanitarian disasters and the need for financial support – specifically within the Organization of Islamic Cooperation (OIC) countries – has forced global humanitarian agencies to consider alternative funding sources. The victims of disaster and those disadvantaged that remain below the poverty line in much of the OIC countries remain concerned about the source of the funding they receive, based on their beliefs. Furthermore, institutions responsible for managing the funding for Sustainable Development Goals (SDGs) targets in their respective countries have also been considering alternative funding. The World Bank and the Islamic Development Bank (IsDB) suggest that the Islamic social finance is largely untapped, with significant potentials for more effective collection and distribution of compulsory alms called zakah and endowments known as waqf within the OIC countries. This chapter assesses the current challenges and opportunities for the Islamic social finance and covers some of the successful cases of the Islamic social finance deployment. The authors review approaches where world-renowned institutions have applied interest-free loans for poverty reduction, banking products for agricultural social financing, the utilization of cross-border social funding for socio-economic development and property management using social finance principles. The authors also assess capital market instruments integrated with the Islamic social finance for managing SDG funding gaps.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

The purpose of this study is three-dimensional flow and heat transfer investigation of water/Al2O3 nanofluid inside a microchannel with different cross-sections in two-phase mode.
Abstract
Purpose
The purpose of this study is three-dimensional flow and heat transfer investigation of water/Al2O3 nanofluid inside a microchannel with different cross-sections in two-phase mode.
Design/methodology/approach
The effect of microchannel walls geometry (trapezoidal, sinusoidal and stepped microchannels) on flow characteristics and also changing circular cross section to trapezoidal cross section in laminar flow at Reynolds numbers of 50, 100, 300 and 600 were investigated. In this study, two-phase water/Al2O3 nanofluid is simulated by the mixture model, and the effect of volume fraction of nanoparticles on performance evaluation criterion (PEC) is studied. The accuracy of obtained results was compared with the experimental and numerical results of other similar papers.
Findings
Results show that in flow at lower Reynolds numbers, sinusoidal walls create a pressure drop in pure water flow which improves heat transfer to obtain PEC < 1. However, in sinusoidal and stepped microchannel with higher Reynolds numbers, PEC > 1. Results showed that the stepped microchannel had higher pressure drop, better thermal performance and higher PEC than other microchannels.
Originality/value
Review of previous studies showed that existing papers have not compared and investigated nanofluid in a two-phase mode in inhomogeneous circular, stepped and sinusoidal cross and trapezoidal cross-sections by considering the effect of changing channel shape, which is the aim of the present paper.

Abstract
Purpose
This study aims to provide an insight into the relationship between design parameters and thermal performance of plate fin heat sinks (PFHSs) incorporating longitudinal vortex generators (VGs) inside a PFHS channel.
Design/methodology/approach
A computational fluid dynamics model of a delta winglet pair VG mounted inside a PFHS geometry is detailed, and the model is validated by comparison with experimental data. The validated model is used to perform a virtual design of experiments study of the heat sink with bottom plate and vertical plate mounted VGs. Data from this study is used to regress a response surface enabling the influence of each of the assessed design variables on thermal performance and flow resistance to be determined.
Findings
The results of this study show that the thermal hydraulic performances of a PFHS with bottom plate mounted VG and vertical plate fin mounted VG are, respectively, 1.12 and 1.17 times higher than the baseline PFHS. Further, the performance variation of the heat sink with VG, relative to delta winglet’s arrangement (common flow up and common flow down), trailing edge gap length and Reynolds number were also evaluated and reported.
Originality/value
For the first time, performance characteristics of delta winglet VGs mounted inside the PFHS are evaluated against different design variables and a polynomial regression model is developed. The developed regression model and computed results can be used to design high performance PFHSs mounted with delta winglet VGs.

Abstract
Purpose
This study aims to determine the effect of health knowledge on nutrition-label use and attitude, and consequently on healthy food choice among Malaysian Muslim consumers.
Design/methodology/approach
This study adopts the positivist, deductive and quantitative approach. A sample consisting of 257 Muslim consumers, at least 15 years old, were selected using systematic street-intercept sampling method. Data collected using a self-administered questionnaire were analysed using descriptive statistics and structural equation modelling (SEM).
Findings
The findings reveal the significant positive effect of health knowledge on nutrition-label use and attitude towards nutrition label, but only attitude towards nutrition label significantly predicts healthy food choice.
Research limitations/implications
Though the findings add to the existing literature, provide useful information on how nutrition label could guide the consumer to make healthier food choices and serve as a reference point that could stimulate and guide future researchers and other relevant parties, this study is limited by several factors that require replication in future research.
Originality/value
This research is perhaps one of the first attempts to consider the role of nutrition label as one of the ways to comply with the Tayyib principle.
