The purpose of this paper is to investigate the structural, electronic and optical properties of pure zinc oxide (ZnO) and transition metal (Tm)-doped ZnO using Tm elements from silver (Ag) and copper (Cu) by a first-principles study based on density functional theory (DFT) as implemented in the pseudo-potential plane wave in CASTEP computer code.

The calculations based on the generalized gradient approximation for Perdew-Burke-Ernzerhof for solids with Hubbard U (GGA-PBEsol+U) were performed by applying Hubbard corrections U_d = 5 eV for Zn 3d state, U_p = 9 eV for O 2p state, U_d = 6 eV for Ag 4d state and U_d = 9.5 eV for Cu 3d state. The crystal structure used in this calculation was hexagonal wurtzite ZnO with a space group of P63mc and supercell 2 × 2 × 2.

The total energy was calculated to determine the best position for Ag and Cu dopants. The band structures and density of states show that Tm-doped ZnO has a lower bandgaps value than pure ZnO because of impurity energy levels from Ag 4d and Cu 3d states. In addition, Ag-doped ZnO exhibits a remarkable enhancement in visible light absorption over pure ZnO and Cu-doped ZnO because of its lower energy region and extended wavelength spectrum.

The results of this paper are important for the basic understanding of the 3d and 4d Tm doping effect ZnO and have a wide range of applications in designing high-efficiency energy harvesting solar cells.

The purpose of this paper is to examine whether Islamic finance could replace or complement the traditional financial system and could guarantee stability in times of crisis.

To achieve the aim, the authors examined both risk-taking and profitability of 94 Islamic banks (IBs) operating in 18 countries observed during the 2006-2013 financial crisis period. A series of bank-specific and other country-specific indicators are combined to explain profitability of IBs as measured by return on assets and return on equity, and risk divided into credit risk measured by impaired loans/gross loans and total equity/net loans, and insolvency risk measured by Z-score. Indeed, a bank is stronger than another if it is stable with a higher capacity to absorb risks, on the one hand, and increased performance on the other.

Using dynamic panel data econometrics (generalized moment method system), the authors estimated five regressions and found the following results: bank capital is found to be the main indicator that contributes to maximizing profitability and stability of IBs and reducing their credit risk. However, the study of liquidity and asset quality determinants often leads to inconclusive results. Nevertheless, they found that Gulf region-operating IBs are more profitable, more solvent and less risky than those operating in the South East Asian region. At the macroeconomic level, the authors could not find a significant relationship between inflation rate and IBs profitability. However, unlike for IBs in Southeast Asia, the authors found that inflation rate improves IBs stability and reduces their credit risk level.

The results of this study have numerous implications for bank management and the different stakeholders (investors, customers). This study identified several factors that may help bank managers to improve their financial outlook by controlling risk level and profitability. These factors could as well help to understand how macroeconomic indicators affect both banking risk and profitability, in particular Islamic banking. Likewise, portfolio managers can use these results to support their decisions to include IBs in their assets portfolios to mitigate potential risk.

This study contributes to the existing literature in two ways. First, this paper provides fresh data and recent information on Islamic banking in Gulf Cooperation Council and South East Asian countries. Second, the obtained results helped us to conclude that the Islamic financial system cannot replace but rather supplements the traditional system. This result may be explained by the fact that Muslims look for Islamic banking products, which conventional banks are not offering.

Green transformation is more than simply a trend; it is a way of life, a set of habits, a field of knowledge and a dedication to resource conservation. Going green is surely a creative and transformative process for both individuals and organizations. This paper aims to “identify,” “analyse” and “categorise” the readiness factors for green transformation process in health care using total interpretive structural modelling (TISM) and neutrosophic-MICMAC.

To address the study objectives, the study used TISM and neutrosophic-MICMAC analysis. To identify the readiness factors, a literature study was conducted, and the factors were face-validated by the healthcare experts. The factors influence on one another were captured by using a scheduled interview with a closed ended questionnaire. The TISM addressed the identification and analysing of factors and the categorization and ranking the readiness factors is addressed by using neutrosophic-MICMAC analysis.

This study identified 11 green transformation process readiness factors for healthcare organizations. The study states that the key factors or driving factors are awareness of green governance principle, environment leadership and management, green gap analysis, information and communication technology and innovation dynamics.

The factor ranking is sensitive to the respondents’ ratings. The study relied on the past literature and experts’ opinion may result in the subjective biases. The complex nature of healthcare ecosystem challenges to capture all the factors. The study focussed on Indian hospitals.

Study significantly impacts the healthcare practitioners, academicians and policymakers by providing critical insights into the readiness factors required for the healthcare green transformation process. The study offers a better understanding of the crucial or key or driving factors that aid in embracing green and sustainable practices.

Identifying a gap in conceptual and theoretical frameworks for green transformation readiness factors in healthcare organizations and in Indian context. The study addresses this gap by aiming to create a thorough theoretical framework and highlighted by its focus on Indian hospitals.

The purpose of this paper is to systematically review and analyse the critical challenges and barriers of e‐government adoption. Such review aims to suggest the salient facts about the issues of successful implementation or adoption of the e‐government services under different circumstances to the researchers.

A total of 78 relevant research papers reviewing and analysing the challenges, barriers, and critical success factors were selected from a set of overall 448 articles on e‐government adoption research. These studies were comprehensively reviewed to examine some of the most significant supply and demand‐side challenges, barriers, and critical success factors explored by different studies in this context.

The findings indicated that technological barriers, lack of security and privacy, lack of trust, lack of resources, digital divide, poor management and infrastructure, lack of awareness, legal barriers, lack of IT infrastructure, and resilience were among some of the most commonly experienced challenges and barriers across the relevant studies. Moreover, it was also found that challenges and barriers associated with supply‐side (i.e. implementation) (C=53) were almost three times to the one applied to the demand‐side (i.e. adoption) (C=18). Furthermore, it was also found that citizen's satisfaction, information accuracy, security, and privacy were some of the critical factors for the success of e‐government initiatives.

This research only reviews the challenges, barriers and critical success factors and leaving apart many other research themes such as impact, digital divide, security, privacy, trust, and risk of e‐government adoption. Moreover, the theoretical and methodological paradigm of this research have not been explored.

This paper presents a comprehensive review of the challenges, barriers, and critical success factors of the e‐government adoption research both with regard to supply as well as demand side. Such review allows us to provide not only a brief account of the issues experienced in the e‐government research, but also prescribes the guidelines for the governments to consider certain facts before successfully implement their e‐government initiatives. Such a comprehensive review of e‐government adoption literature has not been performed earlier.

This study aims to identify and analyze the key barriers that obstruct the effective implementation of Egypt’s e-administration.

Based on a literature review and experts’ opinions, 14 key barriers were identified and classified into dependent, independent and linkage barriers using interpretive structural modeling with the help of MICMAC analysis.

Resistance to change, lack of HR specialized in information and communication technologies and lack of financial support were found to be the most crucial driving barriers to implementing e-administration developments.

To the best of the authors’ knowledge, this study is the first to investigate the barriers to e-administration in Egypt using these methods and is expected to provide useful contributions to help decision-makers better understand e-administration implementation barriers in Egypt.

This paper aims to investigate the dynamic relationship between profit and loss sharing (PLS) financing and banking-specific variables, macroeconomic variables and religiosity in Indonesia.

This study used seven variables, such as PLS financing, Islamic financing rate, risk-sharing deposits, bank size, interest rate, economic growth and level of religiosity. The data used were monthly time series during the 2009–2019 period, and they used the structural vector autoregression method plus ARDL and ECM as a robustness check mechanism.

The results show that in the short term, PLS financing is more influenced by changes in the risk-sharing deposits and bank size variables. Meanwhile, analysis of variance decomposition illustrates that variations in PLS financing are more influenced by the dynamics of PLS financing itself than other variables. This finding also strengthens the characteristics of PLS financing that is immune to the influence of interest rates, and this result can strengthen the implementation of the PLS scheme as an alternative to the monetary channel in the dual banking system in Indonesia.

The immunity of PLS financing to changes in interest rates has implications for the management of Islamic banking risk management. Evaluation must be carried out by increasing the skills of the bankers in response to losses arising from moral hazard and asymmetric information.

This paper used empirical evidence to show the influence of internal and external factors toward PLS financing performance. To the best of the authors’ knowledge, the study on determinants of PLS financing is limited, particularly in the context of Indonesia.

The purpose of this study was to explore the impact of internal and external market orientations on monetary and non-monetary performances of non-conventional Islamic financial institutions. This study further aimed at proposing a conceptual framework, testing it and examining relationships among the variables.

Data for this study were collected from 132 branches of 11 non-conventional financial institutions in Bangladesh using a closed-ended questionnaire. The study considered a structural equation modeling approach for testing the proposed model. A two-step procedure was used for this purpose. First, a measurement model was analyzed through a confirmatory factor analysis; second, the structured model was evaluated to examine relationships between the constructs. Data used in this study confirmed the adequate reliability, convergent and discriminant validity.

The results of the study met the expectations and provided an evidence that both monetary and non-monetary business performances are functions of internal and external market orientations’ efforts. As the results are reported, all three components of internal market orientation, e.g. internal intelligence generation, dissemination and responsiveness, were found to be statistically significant and positively related to monetary and non-monetary performances, except internal intelligence responsiveness with employees’ team spirits. The study also revealed a significant relationship between all three external market orientation components, and business performance, except external intelligence responsiveness, was not found to have a significant relationship with team spirit and customer retention. The results, however, imply that the performance of non-conventional financial institutions is an integrated effort of both internal and external orientations rather than using a single approach.

Findings of this study support the theoretical arguments that non-conventional financial institutions can be successful in attaining all types of performances by initiating and adopting internal and external market-oriented activities. The study further argues the importance of the activities under each market orientation component and suggests non-conventional financial institutions to promote such an initiative if they are to be consistent in their performances.

This paper aims to investigate whether Syariah banks are more financially stable than non-Syariah banks and check the differential impact of explanatory variables in financial health and efficiency in the context of Indonesia.

By using unbalanced panel data from Bankfocus over the period 2011–2018, regression analysis is performed with two response variables representing financial health, ZSCORE for return on average assets, liquid asset to deposit and short-term funding ratio. A number of control variables are used as tools to confirm the hypotheses. To check the robustness of the findings, a model with different specifications has been used.

The results indicate that while Syariah banks present higher insolvency risk (less health) for long-term activity, the opposite is true for short-term activity. Other findings show that Syariah and non-Syariah banks contribute differently to the national system of financial stability owing to varying influential factors on the bank’s health.

This paper presents a comparative analysis between the financial stability of Syariah banks and that of non-Syariah banks in Indonesia by building an empirical framework that allows the author to examine the differential effects of each underlying feature on financial stability in Syariah and non-Syariah banks.

The purpose of this paper is to identify the risks involved in the construction project based on a literature survey (LS), to develop a project risk management (PRM) framework based on Industry 4.0 technologies and to demonstrate the developed framework using Internet of Things (IoT) technology.

A comprehensive LS was carried out to know the different risks involved in the construction project and developed a PRM framework based on Industry 4.0 technologies to increase the effectiveness and efficiency of PRM. Heavy equipment and parameters were identified to demonstrate the developed framework based on IoT technology of Industry 4.0.

This paper demonstrates Industry 4.0 in the various stages of PRM. LS has identified 21 risks for a construction project. The demonstration of the PRM framework has identified the sudden breakdown of equipment and uncertainty of equipment as one of the critical risks associated with heavy equipment of construction project.

The project complexity and features may add a few more risks in PRM.

The PRM framework based on Industry 4.0 technologies will increase the success rate of the project. It will enhance the efficiency and effectiveness of PRM.

The developed framework is helpful for the effective PRM of construction projects. The demonstration of PRM framework using IoT technology provides a logical way to manage risk involved in heavy equipment used in a construction project.

Globally, several studies have shown that hospital building is charged with multiple inherent risks because a large number of users are vulnerable in tragic events. Thus, the need for the fire safety management plan (FSMP) has been proved as an instrument to mitigate fire and related risks in healthcare facilities. In Malaysia, FSMP regarding public healthcare building is yet to be explored in-depth. Therefore, this paper explores the information necessary to develop the FSMP framework for public hospital buildings.

The paper’s objectives were accomplished via a combination of five face-to-face interviews and observations of five selected public hospitals in Pulau Pinang, Malaysia. The five key participants were across the five public hospitals and collated data analysed through thematic analysis with the assistance of MAXQDA 2018.

Findings show that fire safety stakeholders practice system, fire safety action plan and fire risk management were the three main variables that promote fire safety programme and will improve FSMP for Malaysia’s public hospital buildings.

This paper’s data collection is limited to Penang, Malaysia, and a qualitative research approach was used, but this does not deteriorate the strength of the findings. Future studies are needed to consider validating findings from this paper via a quantitative approach.

The suggested framework can be employed by Malaysia’s public hospital authorities as a guideline to mitigate fire hazards in the country’s healthcare facilities.

This paper is encouraging hospital operators and other key stakeholders to improve on their FSMP for healthcare buildings across Malaysia as part of the study implications.
