Abstract

Purpose

The purpose of this paper was to investigate the lubricity of palm biodiesel (PB)–diesel fuel with plastic pyrolysis oil (PPO) and waste cooking biodiesel (WCB).

Design/methodology/approach

Three quaternary fuels were prepared by mechanical stirring. B10 (10% PB in diesel) fuel was blended with 5%, 10% and 15% of both PPO and WCB. The results were compared to B30 (30% PB in diesel) and B10. The lubricity of fuel samples was determined using high-frequency reciprocating rig in accordance with ASTM D6079. The tribological behavior of all fuels was assessed by using scanning electron microscopy on worn steel plates to determine wear scar diameter (WSD) and surface morphology. The reported WSD is the average of the major and minor axis of the wear scar.

Findings

The addition of PPO and WCB to B10 had improved its lubricity while lowering wear and friction coefficients. Among the quaternary fuels, B40 showed the greatest reduction in coefficient of friction and WSD, with 7.63% and 44.5%, respectively, when compared to B10. When compared to B30a, the quaternary fuel mixes (B40, B30b and B20) exhibited significant reduction in WSD by 49.66%, 42.84% and 40.24%, respectively. Among the quaternary fuels, B40 exhibited the best overall lubricating performance, which was supported by surface morphology analysis. The evaluation of B40 indicated a reduced adhesive wear and tribo-oxidation, as well as a smoother metal surface, as compared to B20 and B30b.

Originality/value

Incorporation of PPO and WCB in PB–diesel blend as a quaternary fuel blend in diesel engines has not been reported. Only a few researchers looked into the impact of PPO and WCB on the lubricity of the fuel.

Abstract

Purpose

Every year, hundreds of people have died and thousands have been injured because of insufficient management of well control at oil and gas drilling and production sites. Major causes which have been reported in previous studies included uncontrollable blowouts and failure of blowout preventers because of insufficient safety practices. These onshore and offshore blowout disasters not only harm the work force but also critically affect the environment and marine life. In this research paper, a detailed quantitative survey and qualitative risk assessments (RA) have been carried out for assessing the potentially hazardous activities associated with well control along with their appropriate controls and risk reduction factors and mitigating measures in Middle East and south East Asian countries.

Design/methodology/approach

The sequential explanatory research design has been adopted in this study. Whereas, descriptive statistical approach has been used for the quantitative data analysis of this study. While, in-depth interview approach has been used for qualitative data collection. Similarly, what-if analysis method has been adopted in this study for the identification of effective safety and health risk mitigating factors because it provides in-depth information from health and safety environment experts.

Findings

The cumulative quantitative results based on the response from Saudi Arabian drilling industry have indicated that the well control operation is highly hazardous then Malaysian and Pakistani oil and gas industries. Likewise, findings from what-if analysis approach demonstrate that the drilling crewmembers have repetitively faced life threatening hazards which occur (safety and chemical) during well control onshore and offshore operation because of oil base mud, confined space at site, pinch points and falling during working on blow out preventers. According to the overall result, respondents have highly recommended engineering and administrative hazard controlling factors as most suitable for the elimination of safety and chemical hazards during well control activities.

Practical implications

Besides, the developed methodological framework for the identification of suitable hazard controls can also be effectively used for potential hazards reorganization and identification of suitable hazard controls for other drilling and production industries and regions for accident prevention and safety and health management.

Originality/value

This is a first comparative research study which has been carried out in Malaysian, Saudi Arabian and Pakistani onshore and offshore oil and gas industries for well control health and safety management and reorganization of most effective hazards mitigating factors at drilling sites.

Abstract

Purpose

The swift development of digital platforms and the intricate nature of socialization processes have greatly impacted how young people perceive the legitimacy of the police. This study investigates the influence of different media platforms and methods of socialization in emergencies on the attitudes and beliefs about law enforcement among young individuals. The aim of this review paper is to consolidate existing literature on the influence of various forms of media and social contacts shaping youth attitudes towards the legitimacy of the police, within distinct social and cultural contexts.

Design/methodology/approach

The literature was reviewed narratively, with a focus on major digital bibliographic databases for the purpose of selecting studies. This approach facilitated the examination of overarching concepts across several fields of study in order to develop a thorough comprehension of how media and socialization in emergencies influence young people’s perceptions of the legitimacy of the police. Three major themes were discovered, encompassing the connection of three different theories with the youth perceptions of police legitimacy, impacts from different media sources like news, entertainment and social media and the influence of important socialization agents like family, peers and community.

Findings

The review confirms that the media, regardless of whether it presents good or bad images, has a major impact on the views of youngsters towards the police. It influences their opinions of how trustworthy and legitimate the police are. Modeling and reinforcement, which are key components of social learning, play a crucial role in influencing the impact of media on young people. Community and family connections have significant influence, either strengthening or lessening the effects of media depictions. Although media has the ability to promote understanding and regard for law enforcement, it was also observed that there are challenges associated with the reinforcement of preconceptions and biases.

Practical implications

This research offers fundamental ideas for creating educational and community initiatives that improve positive media depictions of law enforcement and bolster community–police interactions. Additionally, it provides a framework for future studies on media approaches that could facilitate the development of a well-rounded understanding of the legitimacy of law enforcement among young people.

Originality/value

This literature review combines social learning and cognitive theories with empirical research on media to examine the complex and varied effects of media and socialization on how young people perceive the legitimacy of the police. It emphasizes the necessity for a sophisticated comprehension of these connections within the framework of current social dynamics and advancements in technology.

Abstract

Purpose

Throughout the extant studies on Islamic work values, many variations in the concept of Islamic work values were found. This has created some confusions and misunderstandings on what is the core of Islamic work values that is highly emphasized by Islam. The unanimity of Islamic work values is fundamental to Islamic organizations, and businesses in particular, as it indicates ethical, effectiveness and religious reputations of the organizations. This paper aims to identify the core Islamic work values based on Islamic legal texts (the Qur‘an and the Hadith as the two main Islamic sources), the writings of Islamic scholars and then to have experts verify whether or not the identified work values are core Islamic work values.

Design/methodology/approach

The paper used a qualitative approach where Islamic legal texts (the Qur’an and the Hadith) as well as the writing of Islamic scholars were used as a main reference to identify the core Islamic work values. These identified core Islamic work values were later verified by the muftīs. The verification assessment involved six muftīs from Malaysia.

Findings

The final result revealed that 14 core Islamic work values have been verified by the muftīs. These 14 considered core Islamic work values are essential work values of Islam which are important to achieve effective work performance.

Research limitations/implications

The findings presented are useful for managers and employees in Islamic organizations to decide on what Islamic work values that should be given more precedence and to be practised in their organizations.

Originality/value

This is a novel study that combines two approaches, the Islamic legal texts and muftīs verification regarding the work values obtained that can be accepted as the core Islamic work values. Therefore, these findings can be a guide for many future studies in the area of Islamic work values.

Abstract

Purpose

The increasing interest of organizations to innovate and survive in the market, combined with a decreasing level of trust in their leaders, has now led thinkers and researchers to begin exploring beyond traditional leadership theories. The literature indicates that, due to the lack of a strong and explicit moral dimension, positive leadership may be incomplete. The purpose of this study is to understand the creativity mechanism that is fostered by authentic leadership through empowerment and commitment to the supervisor.

Design/methodology/approach

The data of 214 employees were collected from the strategic units (product generation, customer services, marketing and sales) of all five telecoms which are currently operating in Pakistan. The parallel mediation model was used to analyze the hypothesized model.

Findings

Results confirmed that authentic leadership leverages creativity. Mediation results further confirmed that creativity increases when employees feel empowered and are committed to an authentic leader. However, contrast analysis indicated that empowerment has a stronger role in increasing creativity.

Research limitations/implications

Not limited to theoretical debate, the present study emphasized that organizations improve creativity by adopting a management model which delivers moral values along with an efficient, transparent system and empowered culture. Managers should be trained to develop authentic traits so that they can then identify and address critical areas which will serve to nurture creative and innovative behavior in their followers.

Originality/value

Authentic leadership is an emerging concept, yet debate on authentic leadership and creativity is in the establishment phase. The present study highlights that authentic leadership is not simply a consequence of success or the development of a pool of loyal subordinates; rather, empowered leadership at all levels is at the heart of a successful organization.

Abstract

Purpose

Leadership’s dark side has been on the rise, negatively affecting organizations. The phenomenon, however, is not as simple as it seems. Based on social exchange and conservation of resource theories, current research aims to explore the impact of psychological entitlement on despotic leadership, ultimately leading to instigated workplace incivility. Moreover, emotional exhaustion was tested as a mediator and Islamic work ethics as a moderator.

Design/methodology/approach

This study aims to examine the effect of dark side of leadership and for this, the survey approach was used to collect data from 402 bankers from Pakistan’s twin cities (Islamabad and Rawalpindi).

Findings

The results showed that psychological entitlement leads to despotism and despotic leaders become a reason for instigated workplace incivility. Results also showed that emotional exhaustion mediated, and Islamic work ethics moderated the relationship.

Practical implications

Bankers have a demanding job which is further exacerbated by despotic leaders feeling psychologically entitled and instigating employees toward uncivil behaviors as they experience emotional exhaustion. Despotic leaders need to be dealt with to reduce instigated incivility and Islamic work ethics can also aid in improving employee behavior.

Originality/value

Literature available on both antecedents and effects of the leadership’s dark side is limited, and this study strives to contribute by extending the literature available on psychological entitlement, despotic leadership and instigated workplace incivility relationships.
