This study aims to propose a new scheme for designing a high-sensitivity optical biosensor. For this, two agents have been considered: reflection-type micro-resonators, which filter the noise of the pump, and coupled-ring reflectors (CRRs), which are coupled to partial reflecting elements in the bus waveguide to create Fano-resonance. These two agents improve the sensor sensitivity and have low-power optical switching/modulation.

The proposed model is based on the coupling of the CRRs with the Fabry–Pérot cavity. The slope of the Fano-resonance line shape and consequently the sensitivity of the proposed CRRs are higher than those of conventional microring resonators.

The proposed scheme has many characteristics: CRRs have been used to create a higher slope of the Fano-resonance line shape; the sensitivity of the sensor shows improvement on the basis of reflection-type micro-resonators and by the removal of the pump noise; the designed sensor has low-power optical switching/modulation; and the modeling and designing of a novel high-sensitivity resonator is based on coupling the CRRs with the Fabry–Pérot cavity.

The study investigates how consumers' food purchasing habits changed during the Covid-19 pandemic in Italy. The research aims to understand if traditional aspects, health consciousness and environmental concerns have influenced and changed the purchases of food products post-pandemic.

The authors developed a theoretical model to understand whether health consciousness, traditional aspects and environmental concerns affect consumers' purchasing intention. The study collects secondary data to analyse state of the art and investigate consumer behaviour in the agri-food system after the pandemic. Thereafter, a survey was conducted via a convenience random sampling procedure. The data (n = 622) were analysed using the formulated research framework and tested through the structural equation modelling procedure.

The findings reveal that health consciousness and traditional aspects (culinary traditions, ingredients usage from one's territory of origin, products' origin attention) are among the main reasons for purchasing agri-food goods after the pandemic. Instead, environmental concerns negatively affect consumers' purchase intentions.

The study identifies which aspects influenced consumers' purchasing intentions after the Covid-19 pandemic. It also provides insights for food companies and policymakers on the factors to be improved to optimize the agri-food sector following a sustainable perspective and in order to develop effective business strategies.

This study aims to analyse whether Sharia-compliant companies have better sustainability performance, especially in the midst of the COVID-19 pandemic. The pandemic context is worth investigating as there is a concern that companies will reduce their sustainability activities to focus more on economic recovery, thereby leading to lower sustainability performance.

This study uses data from companies listed on Indonesian and Malaysian stock exchanges. These two countries have experienced rapid developments in Islamic finance and possess similar criteria in assigning the Sharia compliance label to a company. The data on sustainability performance and its three dimensions (environmental, social and governance) were gathered from Refinitiv (Thomson Reuters) and analysed using panel data regression.

The results show that Sharia-compliant companies had a higher sustainability performance in all research periods, but not during the COVID-19 pandemic. This implies that the pandemic has not triggered a need for Sharia-compliant companies to improve their sustainability performance. The results can be interpreted that sustainability performance is not only at stake during the COVID-19 pandemic but it can also indicate a “business-as-usual” approach applied by companies regardless of the Sharia-compliant label.

Sustainability performance has been intensively investigated in prior research, but how it is related to the current health crisis and Sharia compliance has been scantily studied and becomes the originality of this research.

The aim of this study is to explore how financial inclusion can impact healthcare access in developing countries using panel data for the period 2004–2022.

To check the impact of financial inclusion on healthcare access, the estimation techniques used are the fixed-effect model (FEM), two-stage least squares (2SLS) and the system generalized method of moments (GMM). The data were collected from different websites such as the World Development Indicators (WDI), the United Nations International Children's Emergency Fund (UNICEF) and the United Nations Educational, Scientific and Cultural Organization (UNESCO).

It is found in the study that financial inclusion has a significant positive effect on healthcare access, and it is also confirmed from previous literature results. The study found that if there are high financial services in the countries, healthcare sectors can be improved by timely facilities, care and funds. Proper development of financial services could be possible by conducting awareness initiatives, financial planning and implementing literacy programs to educate individuals, particularly in rural and underdeveloped areas. According to the results, trade openness and foreign direct investment have a positive impact on healthcare access, while urbanization has negatively influenced healthcare access.

The limitations of this study were restricted to only 29 developing countries. The main reason behind the lack of availability of data insurance data for developing countries was the limitation in generalizing the results.

The government and policymakers must check what are the best financial inclusion programs and policies that can be implemented to improve healthcare access. Previous literature does not show visibly the impact of financial inclusion’s dimensions on healthcare access.

This study presents a pioneering examination of financial inclusion and healthcare in 29 lower- and middle-income countries (developing countries). This study has used a comprehensive financial inclusion index of 29 developing countries to cover the overall impact of financial inclusion on healthcare in these countries.

Green financial technology (FinTech) has received attention for promoting green finance investment and sustainable development. However, how consumer social responsibility and long-term orientation influence the continuance intention of green FinTech users remains unknown in the literature. To fill this gap, consumer social responsibility and long-term orientation are combined with the unified theory of acceptance and use of technology to develop a research model to investigate their moderating effects on the continuance intention of green FinTech users.

A random probability sampling method was adopted, and 377 valid responses were collected to verify the proposed model. Partial least squares structural equation modeling was employed for the data analysis.

Performance expectancy, effort expectancy, social influence and facilitating conditions have significant positive impacts on the continuance intentions of green FinTech users. Surprisingly, consumer social responsibility enhances the effects of performance expectancy and social influence on continuance intention but negatively moderates the effect of facilitating conditions on continuance intention. Moreover, a long-term orientation can increase the impact of facilitating conditions on continuance intention but decrease the impact of performance expectancy on continuance intention.

This paper proposes a research model that reveals how consumer social responsibility and long-term orientation moderate the relationship between the unified theory of acceptance and use of technology (UTAUT) and the continuance intention of green FinTech users to fill a gap in the literature.

This study aims to investigate the factors influencing Indian banks’ choice of green loan disclosure practices. The study analyzes the effect of financial and governance variables to understand the sustainable reporting (through green lending) behavior of Indian banks.

The data on green loan disclosure has been hand-collected from the annual reports using a content analysis approach. Using the data of 26 banks for 12 years (2012–2023), the study uses the panel regression method to control for cross-sectional heterogeneity and generalized methods of the moment to address potential endogeneity issues.

The empirical results depict that larger banks with sufficient risk capital and a strong corporate governance framework demonstrate greater disclosure of green loans. However, growth opportunities and higher market value impedes the reporting of green lending.

The findings of the study will enhance the extant literature on sustainability disclosure by integrating the financial sector companies in the context of an emerging economy. However, future research may include nonbanking finance companies as well.

Banks use societal deposits to invest in productive avenues, and therefore, it is paramount to understand their social and environmental consciousness while evaluating a financing proposal. This research provides a thorough understanding of the sustainable reporting of banks through the lens of green lending.

This research provides unique evidence on the bank-specific determinants of green loan disclosure in an emerging economy context as against the extant literature which primarily focused on sustainable reporting of nonfinancial companies.

The purpose of this paper is to examine the factors that influence Saudi Arabian users’ intentions to continue using fintech payment applications and their satisfaction with these applications.

The unified theory of acceptance and use of technology 2 and DeLone and McLean’s IS success model were integrated to provide a comprehensive framework. A questionnaire was distributed to 401 users of fintech payment applications, and the data collected was analysed using structural equation modelling to test the hypotheses.

The results reveal that factors such as social influence, price value and habit have a positive influence on the continued desire to use fintech payment applications, that the performance expectancy is positively influenced by the level of effort expectancy. Additionally, the quality of the system, service and information provided by the applications has a direct association with user satisfaction, as indicated by the IS Success Model. Moreover, it was observed that customer satisfaction with fintech payment applications positively affects their intention to continue using them.

This study addresses an important gap in the existing literature by examining the factors influencing Saudi Arabian consumers’ intentions to sustain the usage of fintech payment applications. Despite governmental support for the industry, understanding consumer behaviour and satisfaction with these applications remains limited, making this research timely and valuable.

In recent years, Islamic banking (IB) has received a lot of scholarly interest, as seen by the substantial increase in publications on the subject worldwide. The increasing rate of publications on IB indicates that this subject has attracted a substantial amount of scholarly attention. It has also been a prioritized topic for many banking and financial scholars in Bangladesh. This paper aims to conduct a bibliometric analysis to assess the research on IB in Bangladesh.

The method used in this study is a bibliometric analysis of the sample literature collected in January 2022 from the SCOPUS database. The sample size of the study is 120 articles published between 1999 and 2021 which meet the specific selection criteria. To analyze the data, software such as Rstudio (Rshiny), Microsoft Excel and VOSviewer have been used. The analyses were performed in three broad categories: overall performance indicators, citation analysis and cross-dimensional keyword analysis, followed by a brief content analysis that identifies research streams.

This paper shows a notable increase in the number of publications between 2012 and 2021 with Alam M.K. being the highest contributor to this momentum publishing 12 articles. The findings also highlight the most contributing countries, organizations, publications, articles, sources and subjects. Out of 120 articles, this study has identified 14 research streams that have already been investigated by previous authors. The research streams include the growth of IB in Bangladesh; corporate social responsibility; Islamic human resource management; comparative study; customer satisfaction; development issues; efficiency of Islamic banks; green banking; Islami Bank Bangladesh Limited; IB industry; Islamic finance; Islamic microfinance; Shariah governance; and theoretical aspects of IB in Bangladesh. This study further identified future research agenda with specific research questions.

This research is limited to journal articles published in English in Scopus-indexed publications. Further research could include various databases, such as the Web of Science, and increase studied units. While this study focused only on bibliometric analysis and research streams, future studies may center on the systematic review of articles published on specific topics.

Although IB is a rising sector in the financial system of Bangladesh, to the best of the authors’ knowledge, this is the first bibliometric analysis of IB in Bangladesh. The 14 research streams identified in this study also uniquely provide 10 future research agendas with 39 specific research questions.

This paper aims to analyze the scientific trend of research on Islamic banking sustainability (IBS) through a bibliometric study. In particular, the paper extensively investigates all the articles issued through the Scopus database regarding the IBS.

The authors discovered 76 papers that met the function, subject and set requirements by using the phrase IBS. The authors used VOSviewer as an analytical tool and the Scopus website.

IBS publications were found in the period 2005–2022, and the publication trend of IBS research demonstrates that it is growing exponentially after 2018. Malaysia is the leading country in terms of productive authors, universities, number of documents, citations and collaboration research on IBS. The current research trends are summarized into five cluster maps for future research directions: sustainability measurement, sustainability practices, risk and governance, corporate social responsibility (CSR) and IBS theory. The Maqashid al Shariah approach conceptually influences the framework for constructing the dimensions and indicators used to measure the IBS.

The authors retrieved data for their research from the Scopus database; using other databases might result in totally different research patterns with this IBS bibliometric research.

The research encompasses valuable implications for Islamic banking as it offers valuable insights on how to assess the performance of IBS. Particularly, it contributes to identifying the dimensions and indicators needed to measure IBS performance. Furthermore, this research provides strategic initiatives to promote sustainable practices in Islamic banking in terms of green financing taxonomy, services, operations, risk management and governance.

This research is valuable for other scholars as it offers a foundation for the future growth of IBS research, focusing on important sustainability clusters obtained from selected reputable journals. This research is beneficial for regulators in enhancing the roadmap for establishing and enhancing long-term IBS with impacts on socio-economic, environmental and governance.

The study presents a concise review of the bibliometric study in IBS and provides recommendations for future research directions in cluster mapping of themes and subthemes. There is still insufficient research that examines the IBS, in particular, complete insights into the IBS literature review.

This study aims to examine the mediating role of green finance in the relationship between green banking practices and the sustainability performance of banking institutions in developing economies.

The authors performed an empirical investigation by applying the “partial least squares structural equation modeling (PLS-SEM)” based on a representative sample of 414 bank employees working in the National Capital Region, India.

The study’s outcome confirms that employee, top-management, operation and policy related practices substantially influence green finance and banks’ sustainability performance. On the contrary, customer related practices insignificantly influence banks’ sustainability performance. Further, green finance substantially influences the sustainability performance of banking institutions.

This study shed light on green banking practices that can assist in achieving the vision of the “Clean India Mission” of the Indian government. In addition, it encourages policymakers and bank managers to fulfill their social responsibility by engaging employees and customers in cleaner operations to promote banks’ sustainability performance.

This is ground-breaking research that enriches the understanding of green banking practices and green finance by providing a novel theoretical framework concerning the sustainability performance of banking institutions. Theoretically, this paper also broadens the scope of corporate social responsibility literature by applying the resource-based view theory in finance and banking.
