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.

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.

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.

This research aims to investigate the factors that can influence Bumiputera contractors’ acceptance of the Contractor’s All Risks (CAR) takāful (Islamic insurance) product using the theory of reasoned action (TRA).

Using the method of quantitative surveys, 414 questionnaires were collected from targeted Bumiputera contractors in Malaysia (grade G1 to grade G7), except in Sabah and Sarawak, that are registered with the Construction Industry Development Board (CIDB) and are also members of Persatuan Kontraktor Melayu Malaysia (PKMM). The data was analysed using the partial least squares structural equation modeling (PLS-SEM) technique.

The findings from the PLS-SEM analysis show that attitude, subjective norm, religiosity and awareness have a positive relationship with Bumiputera contractors’ acceptance of the CAR takāful product. Religiosity appeared to be the most significant factor influencing Bumiputera contractors’ acceptance of the CAR takāful product.

The respondents in this study only comprised Bumiputera contractors in Peninsular Malaysia, excluding those from Sabah and Sarawak. Therefore, it is not possible to generalise the findings to a broader population.

Takāful operators and their sales and marketing departments need to act proactively in promoting the benefits of investing in CAR takāful that follows Sharīʾah (Islamic law) rules and principles. They should create mechanisms to market CAR takāful better, thus accelerating its acceptance rate among contractors.

The paper uses the proposed extended TRA model, which includes the variables of religiosity and awareness in the TRA model. These variables were successfully integrated in the model, and the findings show that they have significantly contributed to the acceptance of the CAR takāful product among Bumiputera contractors.

The purpose of this paper is to examine the impact of corporate governance and ownership structure attributes on firm performance following the revised code on corporate governance in Malaysia. The study presents a longitudinal assessment of the compliance and implications of the revised code on firm performance.

Two data sets consisting of before (2006) and after (2008-2010) the revised code are examined. Drawing from the largest companies listed on Bursa Malaysia (BM), the first data set contains 92 observations in the year 2006 while the second data set comprises of 282 observations drawn from the largest companies listed on BM over a three-year period, from 2008-2010. Both accounting (return on assets and return on equity) and market performance (Tobin’s Q) measures were used to measure firm performance. Multiple and panel data regression analyses were adopted to analyze the data.

The study shows that there were still cases of non-compliance to the basic requirements of the code such as the one-third independent non-executive director (INDs) requirement even after the revised code. While the regression models indicate marginal significance of board size and independent directors before the revised code, the results indicate all corporate governance variables have a significant negative relationship with at least one of the measures of corporate performance. Independent chairperson, however, showed a consistent positive impact on firm performance both before and after the revised code. In addition, ownership structure elements were found to have a negative relationship with either accounting or market performance measures, with institutional ownership showing a consistent negative impact on firm performance. Firm size and leverage, as control variables, were significant in determining corporate performance.

One limitation is the use of separate measures of corporate governance attributes, as opposed to a corporate governance index (CGI). As a result, the study constructs a CGI based on the recommendations of the revised code and proposes for future research use.

Some of the largest companies did not even comply with basic requirements such as the “one-third INDs” mandatory requirement. Hence, the regulators may want to reinforce the requirements of the code and also detail examples of good governance practices. The results, which show a consistent positive relationship between the presence of an independent chairperson and firm performance in both data sets, suggest listed companies to consider appointing an independent chairperson in the corporate leadership. The regulatory authorities may also wish to note this phenomenon when drafting any future corporate governance codes.

This study offers new insights of the implications of regulatory changes on the relationship between corporate governance attributes and firm performance from the perspective of a developing country. The development of a CGI for future research is a novel approach of this study.

This study aims to identify the inputs from zakat administrators and experts needed for more efficient and effective zakat revenue generation.

Face-to-face interviews with zakat executives, administrators and experts are conducted to collect data.

The findings show three components of input required in the zakat transformation: environment, resources and history. The environmental component comprises five sub-components: companies, banks, zakat recipients, individual zakat payers and the legislative, while the resource sub-components comprise tangible and intangible resources. For history, two components, namely, achievements and challenges, need to be taken into account by the zakat administration.

This study’s main implication is that the components proposed in this study can serve as the basis for developing new strategies for improving zakat collection and distribution management to achieve a more efficient and effective level.

This study will be helpful for policymakers, especially zakat authorities, on how to enhance their administration.

The model developed in this study will help the zakat administration to reform and enhance zakat compliance and zakat revenue generation.
