This study aims to focus on second grade fluid flow over a rotating disk in the presence of chemical reaction. Uniform magnetic field is also taken into account. Because of the smaller magnetic Reynolds number, induced magnetic field is negligible. Heat equation is constructed by considering heat source/sink.

Suitable variables are used to transform nonlinear partial differential equations to ordinary ones. Convergent series solutions are attained by applying homotopy analysis method.

Trends of different parameters on concentration, velocity and temperature are shown graphically. Skin friction coefficient and local Nusselt number are calculated and investigated under the effect of elaborated parameters. An elevation in the value of magnetic field parameter causes collapse in the velocity distributions. Velocity distribution in increasing function of viscoelastic parameter. Temperature and concentration profiles are decreasing functions of viscoelastic parameter. Concentration distribution reduces by increasing the chemical reaction parameter. There is more surface drag force for larger M, while opposite behavior is noted for β.

To the best of the authors’ knowledge, such consideration is yet to be published in the literature.

The changing workplace and the disruption and transformation of business processes brought on by modern technology make it difficult for a firm to maintain its existing plans. A management's ability to succeed is related to sustaining and developing its employees to be innovative workers. The idea is to empower subordinates and share authority with them, which increases efficiency.

In this study, it was anticipated that there is a definite relationship between leadership empowerment and workplace cultures of self-esteem, emotional intelligence and creative thinking. Data were obtained using random sample techniques to confirm the hypothesis. A total of 291 Pakistani private-sector employees were surveyed for this study.

There were positive and substantial links between empowered leadership and creativity, while emotional intelligence and organizational self-esteem have an inverse relationship. For psychological appeal and inventiveness at work, empowerment alone is sufficient. Intellectual stimulus or culture of excessively positive self-esteem may cause numerous limits at work. Hence, management should avoid situations where leaders are predisposed to developing empowering techniques.

This study yields an additional understanding of organizational behavior literature. It was concluded from this study that empowering leaders should avoid using emotional intelligence when scaling up creative strategies. As an alternative, they should develop a culture of self-esteem through emotional intelligence.

Leaders may want to consider demographic values while developing empowerment strategies. It is not recommended to use emotional intelligence and empowerment simultaneously. As a result, this framework suggests a realistic and candid approach that is simple to implement.

Leaders make people aware of the ongoing importance of innovative processes to encourage staff to be creative. Successful leaders may use either empowering culture or leadership empowerment strategies for a more significant appeal. Self-esteem culture may provide a structure of interaction buffer against the other emotions that could counter disruption.

This paper aims to deal with direct torque controller when the five-phase induction motor drive in faulty operation. Precisely, open-phase fault condition is contemplated. Also, the DTC is combined with a speed-adaptive variable-structure observer based on sliding mode observer.

Two novel features are presented. First, the concept of the virtual voltage vector is presented, which eliminates low-frequency harmonic currents and simplifies analysis. Second, speed information is introduced into the selection of the inverter states.

Direct torque control (DTC) is largely used in traditional three-phase drives as a backup to rotor-stator flux-oriented methods. The classic DTC strategy was primarily designed on the base of hysteresis controllers to control two independent variables (speed, torque and flux). Due to the additional degrees of freedom offered by multiphase machine, extensive works have been extended on the ensemble five-phase drives in healthy operation. In addition, the ability to continue the operation in faulty conditions is considering one of the main advantages of multiphase machines. One can find in the literature different approaches treating this subject. The applicability of DTC after the appearing of a fault has not been enclosed in the literature.

Theoretical development is presented in details followed by simulation results using Matlab/Simulink to analyze the performance of the drive, comparing with the behavior during healthy situation.

This study aims to dissect and understand the latent themes of Islamic work ethic (IWE) and explore the driving factors of IWE research.

Structural topic modeling (STM), a sophisticated machine learning technique, was used to analyze a corpus of 205 articles sourced from the Scopus database. These articles cover the 36 years of research on IWE, from 1988 to 2024. Moreover, negative binomial regression was applied to examine the driving factors of IWE research.

The STM analysis unfolds ten topics in conjunction with IWE including individual success, workplace dynamics, organizational work ethics, knowledge management, employee citizenship behavior, financial ethics, job satisfaction, organizational commitment, performance enhancement and leadership. The further STM outputs included word clouds, prevalence proportions, correlation matrix, heatmap, relationship of topics with metadata, topic prominence in the publishing journals and, finally, illustrating trends and future prospects of research on IWE. The results of negative binomial regression reveal that number of authors, article age, journal indexing, authors from multiple countries and number of references are strong drivers of fostering research in IWE, by having significant positive impacts on total citations.

The insights from this study provide valuable guidance for businesses and organizations looking to integrate IWE principles into their operations. By promoting values such as fairness, hard work and ethical behavior, organizations can foster a more inclusive and morally grounded workplace culture. This, in turn, may lead to enhanced employee satisfaction, greater organizational commitment and improved overall performance. Additionally, the emphasis on ethical practices can contribute to broader societal benefits, such as increased trust in business practices and a stronger alignment with social responsibility initiatives.

This is a unique study that explores the latent themes and characteristics of the IWE literature through STM and provides insights on the future research directions. In addition, this study also examines the driving factors of IWE research.

This study aims to examine the relationship between Islamic work ethics (IWE), job embeddedness and knowledge-sharing behaviors. It also tested the mediating effects of job embeddedness and the moderating effects of organizational identification on this relationship.

A total of 396 respondents from Islamic banks in Indonesia participated in this study. Data analyzes for hypothesis testing were conducted using Hayes’ PROCESS macro-based hierarchical regression.

The findings suggest that subscribing to IWEs positively and significantly impacts job embeddedness and knowledge-sharing behaviors. Moreover, job embeddedness was confirmed as a mediator in the relationship between IWEs and knowledge-sharing behavior. Finally, the effects of IWEs on knowledge-sharing behaviors are stronger when employees attain a high level of organizational identification.

By encouraging the adoption of IWEs, organizations can develop job embeddedness and promote knowledge-sharing in the workplace, especially in an Islamic banking context. Therefore, managers should strengthen the mutual understanding among employees regarding IWE principles. They should be consistently applied and disseminated by Islamic banks’ management in the form of a formal code of ethics that applies to all actions within the organization.

This study was conducted to extend the understanding of IWE and its relationship with workplace outcomes in modern organizations. Drawing on the conservation of resources theory, social identity theory and Islamic theology, new insights are provided by explaining the psychological mechanism underlying the relationship between IWEs and knowledge-sharing behaviors while proposing organizational identification as the boundary condition.

This chapter provides a study of how gambling companies use the cultural and social capital of Newcastle United Football Club, in the English Premier League, to establish a connection with the club's fans to promote gambling. Newcastle United had two gambling sponsors during the period of this study, from 2017 to 2020, including a front of shirt sponsor, FUN88, an online gambling brand with a large following in Asia. Data were gathered from a range of sources, including from the social media platform, Twitter, to identify the methods the company used to engage fans and to encourage betting on the outcome of matches. The data from the study were explored thematically to describe the relationship developed between the football club and its principal gambling sponsor in order to drive business for the latter with the club's followers. The findings showed how FUN88 evoked Newcastle United's cultural tradition to promote gambling and generate business globally whilst the club actively promoted their ‘primary partner’ through its media channels. The lure of free match tickets was used to encourage fan engagement. Corporate practices promote the consumption of unhealthy commodities through their marketing whilst consumers (fans) are responsibilised for any harms engendered by their gambling practices. The ubiquity of gambling brands has enabled gambling to become a normalised part of football culture. The findings from this study show how FUN88 has used all elements of the sponsorship assemblage to create an emotional connection whilst engaging with Newcastle United's fans to increase consumption of its products.

This paper aims to explore the director’s work ethics with particular attention given to the Islamic perspectives and prophetic character toward sustaining the performance of the business organizations. As at now, there is a limited code of ethics that can be a guidance for the business organizations and its leaders specifically.

This paper examines and reviews the foundation and prior studies on directors’ work ethics and Islamic work ethics. Then, briefly discuss and present a conceptual review of the directors’ work ethics based on prophetic characters, as well as its application in modern business activities.

Based on Quran and Hadith, this paper proposes that four fundamental moral characters of directors are siddiq (truthfulness), fatanah (intelligent), tabligh (deliver) and amanah (trust).

This paper is conceptual in nature, thus further research needed to empirically test all the characters in actual practices.

The outcome of this paper contributes in way of it can be used and applied by the firm and policymakers to construct a comprehensive code of ethics that based on the Islamic values.

This paper is original as it attempts to suggest the appropriate constructs of directors’ work ethics from the religious studies in the ethics and management literature. These constructs able to increase the integrity and moral behaviors of the directors, which eventually preventing them from a commit in various unethical and malpractices that may obstruct the progress of the country’s economic development and growth.

The theoretical findings serve as a foundation for further research into understanding sulfide-based solid-state electrolytes, ultimately advancing the progress of all-solid-state batteries.

The electronic properties of Li₇P₃S₁₁ are thoroughly explored through first-principles calculations.

This investigation encompasses the intricate atom-dominated valence and conduction bands, spatial charge density distribution and the breakdown of atom and orbital contributions to van Hove singularities. Additionally, the compound’s wide and discrete energy spectra reflect the substantial variations in bond lengths and its highly anisotropic geometric structure. The complex and nonuniform chemical environment indicates the presence of intricate hopping integrals.

This study provides valuable insights into the critical multiorbital hybridizations occurring in the Li-S and P-S chemical bonds. To validate the theoretical predictions, experimental techniques can be employed. By combining theoretical predictions with experimental data, a comprehensive understanding of the geometric and electronic characteristics of Li₇P₃S₁₁ can be achieved.

This study refines theory of social capital by nesting it within a cultural context. More specifically, it aims at describing, explaining, and predicting the role of wasta, a social capital concept, as a moderator in the relationship between employees' ethical idealism and work engagement in Lebanon.

Based on a survey questionnaire translated from English into Arabic, 317 responses were collected from employees in Lebanon. Confirmatory factor analysis and hierarchical regression analysis were employed to test the hypothesized relationships among the examined variables.

Ethical idealism was found to be positively related to work engagement, and wasta was found to moderate the relationship between ethical idealism and work engagement. Work engagement levels of employees who displayed high levels of ethical idealism were less influenced by the negative effect of wasta than work engagement levels of employees who displayed low levels of ethical idealism.

Human resource managers, international negotiators, and global executives in Lebanon may use the findings of this study to update corporate human resources systems, such as employee recruitment and selection, handbooks, orientation, training programs, and performance appraisal, to better address employee attitudes toward the practice of wasta.

The study adds ethical idealism as an antecedent of work engagement, demonstrating the significant impact that wasta, with its positive and negative characteristics, has on the engagement of employees from the Arab world.

The increasing ethical misconduct at job place demands to understand the role of ethics in a wide variety of disciplines. This paper aims to empirically investigate the mediating mechanism of life satisfaction and subjective happiness between Islamic work ethics – innovative work behavior (IWB) and organizational citizenship behavior (OCB).

The sample comprised 296 employees and 58 head of departments (HODs) of top 11 business schools in Pakistan. The data of the study were collected in three waves and from two different sources (faculty members and their HODs) through questionnaire. The statistical technique SEM analysis was applied to inspect the proposed direct and mediating hypotheses.

Taken together, the findings revealed that Islamic work ethics (IWE) improves quality of life and by following IWE at workplace, employees feel pleasure and show satisfaction from life. The results supported the mediating role of both life satisfaction and subjective happiness between IWE-IWB and IWE-OCB.

This study provides practical insight that Islamic business ethics plays an important role at workplace and improves quality of life and individual behavior.

The current research is unique, as it empirically investigates the mechanism quality of life phenomena which connects IWE and individual behavior (innovative and citizenship). The mechanism quality of life is less studied, and therefore this study fills the gap of scant literature.
