Abstract
Purpose
Miniplate shapes determine the fixation stability to promote best healing and osseointegration process of mandibular fracture. In clinical treatment, the common method used two straight-type miniplate or I-shape miniplate; sometimes this method is not stable enough or limited by the fracture geometry and caused high risk of failure due to screw loosening. This paper aims to investigate a new type of miniplate called V-shape miniplate design as an alternative to the standard straight plate based on total displacement, von Mises stress, stress transfer parameter (STP) and strain energy density transfer parameters (SEDPTs) for two types of bite force condition, which is cutting and chewing condition.
Design/methodology/approach
The 3D fixation models were constructed and the finite element (FE) simulation is based on the two-bite force load that ranges from 50 to 700 N based on cutting and chewing bite force condition using ANSYS Workbench 19.2.
Findings
In result comparison, the maximum loading of the V-shape miniplate can reduce deformation by 5.9%, reduce stress by 0.58% reduce strain by 8.1% in cutting condition while reducing deformation by 6.43%, reduce stress by 15.25%, reduce strain by 10.1% in chewing condition. To assess the stress transfer behavior of miniplates fixations to the mandibular bone, the STP and SEDPT were evaluated at the normal cortex screw and the locking head screw. In the simulation, the locking head screw is vertical to the bone structure while the cortex screw is 95 degrees to the bone structure, as a result, the STP value for locking head screw is 1.0073 while in cortex screw is 0.7408.
Research limitations/implications
Meanwhile, the SEDPT value for locking head screw is 2.7574 and 1.8412 for cortex screw.
Practical implications
Clinically, V-shape miniplate has shown factual data that can be used for prototyping. STP and SEDTP values provide evidence of how fixation stability is better than I-shape miniplate.
Originality/value
In conclusion, the newly designed V-shape miniplate has overall better stability than the standard I-shape miniplate, and the locking head screw has the STP value closer to 1 than the standard cortex screw; it means the locking screw is better in reducing the stress shielding.

Abstract
Purpose
Organizational culture is a determinant for quality improvement. This paper aims to assess organizational culture in a hospital setting, understand its relationship with perceptions about quality of care and identify areas for improvement.
Design/methodology/approach
The paper is based on a cross‐sectional survey in a large clinical department that used two validated questionnaires. The first contained 20 items addressing perceptions of cultural typology (64 respondents). The second one assessed staff views on quality improvement implementation (48 faculty) in three domains: leadership, information and analysis and human resource utilization (employee satisfaction).
Findings
All four cultural types received scoring, from a mean of 17.5 (group), 13.7 (developmental), 31.2 (rational) to 37.2 (hierarchical). The latter was the dominant cultural type. Group (participatory) and developmental (open) culture types had significant positive correlation with optimistic perceptions about leadership (r=0.48 and 0.55 respectively, p<0.00). Hierarchical (bureaucratic) culture was significantly negatively correlated with domains; leadership (r=−0.61, p<0.00), information and analysis (−0.50, p<0.00) and employee satisfaction (r=−0.55, p<0.00). Responses reveal a need for leadership to better utilize suggestions for improving quality of care, strengthening the process of information analysis and encouraging reward and recognition for employees.
Research limitations/implications
It is likely that, by adopting a participatory and open culture, staff views about organizational leadership will improve and employee satisfaction will be enhanced. This finding has implications for quality care implementation in other hospital settings.
Originality/value
The paper bridges an important gap in the literature by addressing the relationship between culture and quality care perceptions in a Pakistani hospital. As such a new and informative perspective is added.

Abstract
Purpose
Buy Muslim’s First campaign started with the primary aim of urging the Muslim community to be more vigilant about halal or Shariah-compliant products, leading to a number of halal-related issues, triggered by the exploitation or misuse of the halal logo in Malaysia. The purpose of this study is to gain an understanding of the purchase intention for Muslim-made products by applying the theory of planned behaviour (TPB). Halal consciousness was integrated as a moderating influence on the purchase intention of Muslim-made products.
Design/methodology/approach
Data collection was performed through a self-administered questionnaire which was distributed through convenience sampling method. Therefore, a useful sample comprising 152 Malay Muslim participants aged over 18 was collected. For hypothesis testing, hierarchical multiple regression analysis was implemented.
Findings
It was found that the participants’ attitudes towards the purchase of Muslim-made products and their perceived behavioural control significantly influenced their purchase intention, but the subjective norm did not impact this intention. Furthermore, halal consciousness moderated the relationships among all the independent and dependent variables. Halal consciousness moderated the relationship between participants’ attitudes towards Muslim-made products and their perceived behavioural control towards the purchase intention; however, this moderation did not occur through the subjective norm and the purchase intention.
Research limitations/implications
As the findings of this study were limited to the Muslim population in Malaysia, it might be difficult to generalize for other nations that have no similarities with the Malaysian Muslim culture.
Practical implications
The findings of this study may support Muslims to implement more effective marketing strategies that attract the target customers to purchase Muslim-made products. Effective promotion may attract potential customers as well.
Originality/value
The halal consciousness among Muslim consumers is important for the moderation and prediction of consumers’ intention to purchase Muslim-made products.

Abstract
Purpose
This paper aims to report the findings of semi‐structured interviews with management, external auditors and audit committee members in Malaysia concerning the role of the audit committee in resolving auditor‐client disagreements.
Design/methodology/approach
An exploratory case study method was applied in seven publicly listed companies in Malaysia. In each company interviews were conducted with an audit committee chair/member, the finance manager/CFO and the external auditor.
Findings
The study finds that, when the issue is very material, the audit committee plays a mediating role as a third‐party intermediary who provides assistance to resolve the dispute. The authority of the committee to act as a mediator comes from its oversight responsibilities, its understanding and awareness of possible issues and the members' accounting and business expertise. Mediation techniques used include controlling the agenda, gathering information, advising and solving problems. With two exceptions, the interviews indicate that the audit committee does not take sides when helping to resolve a dispute. The outcome from the mediation process is generally a compromise solution.
Research limitations/implications
The study is based on 21 interviews undertaken in Malaysia. Hence, the findings may not be generalizable to other cultures and jurisdictions. Further, while a number of mediation techniques used by audit committees are identified, the paper does not examine in‐depth the mediation processes used in resolving disagreements.
Originality/value
The study extends the auditor‐client negotiation literature by examining whether the audit committee plays a mediating role to help resolve disagreements. The findings demonstrate that audit committee effectiveness can extend beyond a pure oversight role to more active involvement in resolving contentious accounting issues.

Abstract
Purpose
The paper aims to examine whether attitude, subjective norm and perceived behavioural control (PBC) would influence the level of acceptance of the benefidonors concept amongst waqf stakeholders. In addition, antecedents to attitude, namely, religiosity, level of knowledge, perception of fairness and self- efficacy, were also examined, resulting in eight hypotheses of the study.
Design/methodology/approach
This research used an online survey questionnaire. Respondents are waqf stakeholders comprising of donors, beneficiaries, waqf managers, activists, volunteers and the community. A total of 198 usable responses were analysed using SmartPLS version 3.0.
Findings
The research model explains 57.5% of the intention to accept the benefidonors concept. Six hypotheses were accepted, which includes attitude, subjective norms and perceived behaviour control to accept the concept; perception of fairness to attitude; and self-efficacy and facilitating resources to PBC.
Research limitations/implications
The study looks at six groups of waqf stakeholders but could not distinctly categorize the stakeholders into groups because of their multiple roles. Future studies can examine each of the different group.
Practical implications
Waqf institutions should improve their efforts to encourage beneficiaries and donors to become benefidonors such as having an online platform and providing training for waqf stakeholders.
Social implications
Benefidonors can help uplift the poverty level of the less privileged, reduce cost of service and thus assist to reduce the gap of income inequality in the community.
Originality/value
To the best of the authors’ knowledge, this is the first empirical study that examines the intention of Waqf stakeholders to accept the benefidonors concept.

Abstract
Purpose
Current evidence indicates that humans and animals are at increased risk of multiple health challenges due to microplastic (MP) profusion. However, mitigation is constrained by inadequate scientific data, further aggravated by the lack of evidence in many African countries. This review therefore synthesized evidence on the current extent of MP pollution in Africa and the analytical techniques for reporting.
Design/methodology/approach
A literature search was undertaken in research databases. Medical subject headings (MeSH) terms and keywords were used in the literature search. The authors found 38 studies from 10 countries that met the inclusion criteria.
Findings
Marine organisms had MPs prevalence ranging from 19% to 100%, whereas sediments and water samples had between 77 and 100%. The most common and dominant polymers included polypropylene and polyethylene.
Practical implications
This review shows that most studies still use methods that are prone to human errors. Therefore, the concentration of MPs is likely underestimated, even though the authors’ prevalence evaluations show MPs are still largely pervasive across multiple environmental matrices. Also, the study reveals significant spatial disparity in MP research across the African continent, showing the need for further research in other African countries.
Originality/value
Even though some reviews have assessed MPs pollution in Africa, they have not evaluated sample prevalence, which is necessary to understand not only concentration but pervasiveness across the continent. Secondly, this study delves deeper into various methods of sampling, extraction and analysis of MPs, as well as limitations and relevant recommendations.
