This study aims to investigate the feasibility of proposed microgrid (MG) that comprises photovoltaic, wind turbines, battery energy storage and diesel generator to supply a residential building in Grindelwald which is chosen as the test location.

Three operational configurations were used to run the proposed MG. In the first configuration, the electric energy can be vended and procured utterly between the main-grid and MG. In the second configuration, the energy trade was performed within 15 kWh as the maximum allowable limit of energy to purchase and sell. In the third configuration, the system performance in the stand-alone operation mode was investigated. A whale optimization technique is used to determine the optimal size of MG in all proposed configurations. The cost of energy (COE) and other measures are used to evaluate the system performance.

The obtained results revealed that the first configuration is the most beneficial with COE of 0.253$/KWh and reliable 100%. Furthermore, the whale optimization algorithm is sufficiently feasible as compared to other techniques to apply in the applications of MG.

The value of the proposed research is to investigate to what extend the integration between MG and main-grid is beneficial economically and technically. As opposed to previous research studies that have focused predominantly only on the optimal size of MG.

This study aims to investigate the daily performance of the proposed microgrid (MG) that comprises photovoltaic, wind turbines and is connected to the main grid. The load demand is a residential area that includes 20 houses.

The daily operational strategy of the proposed MG allows to vend and procure utterly between the main grid and MG. The smart metre of every consumer provides the supplier with the daily consumption pattern which is amended by demand side management (DSM). The daily operational cost (DOC) CO2 emission and other measures are utilized to evaluate the system performance. A grey wolf optimizer was employed to minimize DOC including the cost of procuring energy from the main grid, the emission cost and the revenue of sold energy to the main grid.

The obtained results of winter and summer days revealed that DSM significantly improved the system performance from the economic and environmental perspectives. With DSM, DOC on winter day was −26.93 ($/kWh) and on summer day, DOC was 10.59 ($/kWh). While without considering DSM, DOC on winter day was −25.42 ($/kWh) and on summer day DOC was 14.95 ($/kWh).

As opposed to previous research that predominantly addressed the long-term operation, the value of the proposed research is to investigate the short-term operation (24-hour) of MG that copes with vital contingencies associated with selling and procuring energy with the main grid considering the environmental cost. Outstandingly, the proposed research engaged the consumers by smart meters to apply demand-sideDSM, while the previous studies largely focused on supply side management.

The purpose of this study is to develop a new whistleblowing scale considering the conventional and Islamic perspectives in combating corruption. Whistleblowing has received great attention because it helps the corruption prevention process by revealing bad practices, improving transparency and ensuring accountability. However, not many scholars have focused on the concept of whistleblowing in the Islamic context.

The study uses a theoretical inquiry design, delving into the literature to thoroughly examine whistleblowing likelihood, Kohlberg’s theory and Maqasid Shariah. Through qualitative content analysis, relevant concepts are scrutinized and synthesized. The integration of Kohlberg’s theory and Maqasid Shariah aims to offer a comprehensive framework for comprehending whistleblowing likelihood, integrating perspectives from both Western and Islamic traditions.

This study has conceptualized the integration of the six stages of Kohlberg and Maqasid Shariah to understand whistleblowing likelihood. The study offers a scale to explain whistleblowing likelihood based on the two theories.

The correlation between Kohlberg and Maqasid Shariah reveals a nuanced relationship between individual moral evolution and Islamic ethical imperatives, in the context of whistleblowing likelihood. As individuals progress through Kohlberg’s stages, aligning with Maqasid Shariah’s emphasis on societal well-being, their inclination to blow the whistle evolves from early considerations of fear and conformity to a commitment to universal ethical principles and justice.

The new scale integrating Kohlberg and Maqasid Shariah aids ethical climates in organizations by assessing employees’ moral development and promoting ethical leadership through tailored training. Aligned with Islamic values, the scale becomes a tool for fostering ethical behavior and organizational culture, emphasizing justice and commitment to higher ethical objectives. Managers must delicately balance justice and community harmony when implementing whistleblowing initiatives to ensure a positive impact on both ethical principles and organizational cohesion.

By integrating the six stages of moral development proposed by Kohlberg, the new scale plays a role in promoting transparency and accountability for sustainable development. Furthermore, its alignment with Maqasid Shariah contributes to addressing corruption and advocating for social justice, making the scale a catalyst for societal well-being that respects cultural and religious values. Ultimately, the scale supports a socially responsible approach, reinforcing ethical behavior and contributing to the broader global agenda for sustainable and just societies.

The new scale integrating Kohlberg and Maqasid Shariah offers an innovative and interdisciplinary approach to assessing whistleblowing likelihood. This fusion provides a nuanced understanding of individuals’ ethical reasoning, aligning universal moral principles with Islamic ethics. The scale not only broadens the conceptual framework for evaluating ethical decision-making but also respects cultural diversity, making it inclusive and applicable across diverse global contexts.

This article seeks to explore the key motivational factors driving Generation Z (Gen Z), within the context of the significant influence of the digital paradigm, employing the Self-Determination Theory (SDT) as a content motivational framework.

Utilizing an abductive methodology, the study combines deductive insights from a systematic literature review on Gen Z’s motivational predictors with inductive findings from a workshop involving six medium and large - scale global manufacturing companies. The synthesis of these results contributes to the creation of a matrix that highlights the relationship between motivational predictors and the psychological needs stemming from intrinsic motivation.

This paper suggests an extension of SDT tailored for Gen Z, identifying six motivational factors—autonomy, competence, relatedness, purpose, flow state, and achievement.

This research emphasizes the need for a modern leadership approach capable of effectively overseeing remote teams, fostering a balanced integration of personal and professional aspects, and nurturing individual purpose. This approach goes beyond fulfilling the basic needs of Maslow’s pyramid to focus on elevating the significance of work, training, and employee engagement to satisfy higher levels of self-actualization and transcendence.

The study delves into the motivations of Gen Z, a demographics that has received limited attention in the existing literature. The integration of the six factors with SDT reflects a synthesis tailored to the distinctive characteristics of Gen Z and aligns with the principles of the PERMA model within positive psychology.

Over the past several decades, instructional leadership has gradually gained increasing currency as a key role of school principals throughout much of the world. This is also the case in Malaysia where educational research, policy and practice have brought the instructional leadership role of the principal front and center. The purpose of this paper is to assess the conceptual models, research methods, and foci of scholars in the study of principal instructional leadership in Malaysia over the past 30 years.

Systematic methods were used to identify all studies conducted in Malaysia that had used the Principal Instructional Management Rating Scale (PIMRS) (Hallinger, 1982/1990/2015) as the data collection instrument. This search yielded a database of 120 studies completed between 1989 and 2016 written in both English and Bahasa Malay. Common data were extracted from the 120 research reports, coded and entered into a MS Excel spreadsheet for analysis. Quantitative methods were employed to analyze modal trends and synthesize patterns in the data across the studies.

The search identified 120 PIMRS studies, 90 percent of which had been conducted since 2005. This represented a surprisingly large corpus of studies. Over 75 percent of the Malaysian studies of principal instructional leadership had been conducted as graduate (master and doctoral) theses, relatively few of which had achieved publication in journals. The authors’ analysis found that most studies had used lower order (i.e. bivariate, direct effects) conceptual models and relied heavily on descriptive and simple correlational statistical tests. The lack of consistent results within the database of studies was attributed largely to limitations in research design and quality.

The 120 PIMRS studies conducted in Malaysia comprise a surprisingly large corpus of research on principal instructional leadership. Indeed, the Malaysian corpus is second only to the USA in terms of the number of PIMRS studies of principal instructional leadership. Nonetheless, limitations in the research models and methods employed in these studies suggest a need for stronger methodological training before Malaysian scholars can achieve the goal of contributing useful knowledge to the local and global knowledge base. Specific recommendations are offered for strengthening the quality of research.

The recent expansion of higher education in Malaysia – like other developing societies – has yielded progress in the scope of research production. However, numerous challenges remain in transforming the potential for useful knowledge production from graduate research into reality.

This is the first review of research on principal leadership conducted in Malaysia. The review follows efforts by scholars to systematically identify the boundaries of knowledge in educational leadership and management within East Asian societies (e.g. China, Singapore, Vietnam, Taiwan and Hong Kong). Moreover, this is the first review of research that examines the use of the PIMRS in a single society.

Several research models have been proposed in the existing literature to understand the intention to use Islamic banking where conventional bank customers are not primarily addressed. Upon measuring the level of Islamic financial literacy (IFL) among the customers of conventional banks in the UAE, the purpose of this paper is to examine the direct and indirect effects of IFL, awareness, cost and benefit, reputation and attitude towards Islamic banking on the intention of potential customers to use Islamic banking.

Using judgmental sampling techniques, questionnaires were distributed to working individuals who did not have accounts with Islamic banks. A total of 350 completed and usable questionnaires were received and used for further analysis. The SmartPLS 3.0 software was used to analyse the data.

The results revealed that the level of IFL was high across the respondents and differed significantly as a function of gender, income level and years of work experience. The findings showed that IFL, awareness, reputation and attitude towards Islamic banking significantly influenced the intention to use Islamic banking, while cost and benefit appear not to. Interestingly, IFL was negatively correlated with the intention to use Islamic banking, but when the attitude towards Islamic banking mediated the relationship between IFL and the intention to use Islamic banking it then became positive.

Future research should consider looking at non-Muslim economies, which might be more vulnerable to IFL. In addition, a comparison between the current customers of Islamic banks and potential customers might be relevant to see whether the IFL of the current customers differs from the new customers.

The implications of the research are twofold. First the study suggests that IFL is crucial for an Islamic bank’s potential new customers. Islamic bank managers should design and focus their policies toward enriching the knowledge of the public about Islamic banks and their products. Second, IFL alone does not lead to a higher level of intention to use Islamic banks unless there is a positive attitude towards such banks.

To the authors’ knowledge, this is one of the first studies to consider the IFL measure used in this paper. Therefore, this study will be the foundation for future research on IFL.

Halal certification is predominantly linked with the product and its production process. However, certifying price, place and promotion (3Ps) has not received enough attention theoretically and empirically. Against this backdrop, this study aims to unravel the halal certification of the marketing mix in Bangladesh’s cosmetics industry.

Fourteen mid and top executives from 12 national, international and multinational cosmetic companies were interviewed from November 2023 to January 2024. The data were analyzed using ATLAS.ti 2024 to showcase content, concept, sentiment, correlation, network and thematic analysis, exploring respondents’ perceptions aligned with Islamic principles.

The respondents held highly negative perceptions about certifying halal pricing, followed by promotion and supply chain or place. The mixed perceptions illustrate that certifying the halal product is easier than certifying the halal price, promotion and place (3Ps). Conditional and positive perceptions can foster halal certification of the entire marketing mix, while negative perceptions seem to be a threat to the halal cosmetics industry.

The findings have implications for academic, managerial and policymaking issues, benefiting halal cosmetics consumers. Based on this empirical study, halal stakeholders can determine the likelihood of certifying the entire marketing mix.

This study proposes certifying the halal status of the marketing mix against the backdrop of the scarcity of theoretical and practical premises.

This paper aims to explore the level of hibah knowledge among Muslims in Kedah and investigate its determinants, consisting of education level, education stream, religiosity, social influence and social media.

This study is quantitative in nature. Questionnaires were distributed to collect data from Muslims in Alor Setar, Kedah. In total, 195 questionnaires were collected and data were analyzed using descriptive analysis, correlation analysis and multiple regression analysis.

The study finds that Muslims in Alor Setar, Kedah have good knowledge of hibah. Further, education stream, religiosity, social influence and social media were identified as significant factors that influence their knowledge of hibah.

The first limitation is its narrow focus in surveying Muslims only in Alor Setar, Kedah. The second limitation is the limited number of determinants used in investigating hibah knowledge among Muslims and the techniques used in analyzing the data. Despite these limitations, the study’s findings provide invaluable insights into the factors influencing hibah knowledge among Muslims in Alor Setar, Kedah.

This study provides insights regarding the significant personal factors and environmental factors to increase Muslims’ knowledge of hibah. The link between the Islamic education stream and hibah knowledge provides a clear indication that Islamic education can curb the economic problems caused by the substantial amounts of frozen and unclaimed assets in Malaysia. A significant relationship between the environmental factors (social influence and social media) and hibah knowledge also implies that the government and private agencies related to Islamic estate planning and management may use these significant determinants as part of the marketing strategy to increase the usage of hibah as an alternative tool for estate planning.

This study contributes to a better understanding of Muslims’ knowledge about hibah. The government and related agencies in Islamic estate planning and management can now gain better insights into Muslims’ level of knowledge about hibah and the factors influencing their knowledge of hibah as an effective tool for Islamic estate planning and management. Hence, more effective strategies can be recommended to enhance the knowledge of Muslims on hibah. The findings of this study should be of value to the government in its effort to address the increasing number of frozen estates in Malaysia.
