This study aims to investigate the machining performance of CVD-coated carbide tools by considering most crucial machinability aspects: cutting force, tool life, surface roughness and chip morphology in high-speed hard turning of AISI 4340 alloy steel under a sustainable minimum quantity lubrication (MQL) environment.

The purpose of this study is to analyze the performance of coated carbide tools under MQL environment therefore, machining tests were performed in accordance with the Taguchi L9 orthogonal array, accommodating the three crucial machining parameters such as cutting speed (V = 300–400 m/min), feed rate (F = 0.1–0.2 mm/rev) and depth of cut (DOC = 0.2–0.4 mm). The measured or calculated values obtained in each experimental run were validated for normality assumptions before drawing any statistical inferences. Taguchi signal-to-noise (S/N) ratio and analysis of variance methodologies were used to examine the effect of machining variables on the performance outcomes.

The quantitative analysis revealed that the depth of cut exerted the most significant influence on cutting force, with a contributing rate of 60.72%. Cutting speed was identified as the primary variable affecting the tool life, exhibiting a 47.58% contribution, while feed rate had the most dominating impact on surface roughness, with an overall contributing rate of 89.95%. The lowest cutting force (184.55 N) and the longest tool life (7.10 min) were achieved with low machining parameters at V = 300 m/min, F = 0.1 mm/rev, DOC = 0.2 mm. Conversely, the lowest surface roughness (496 nm) was achieved with high cutting speed, low feed rate and moderate depth of cut at V = 400 m/min, F = 0.1 mm/rev and DOC = 0.3 mm. Moreover, the microscopic examination of the chips revealed a serrated shape formation under all machining conditions. However, the degree of serration increased with an incremental raise with cutting speed and feed rate.

The study is limited to study the effect of machining parameters within the stated range of cutting speed, feed rate and depth of cut as well as other parameters.

Practitioners may consider to adopt this machining technique to create more sustainable working environment as well as eliminate the disposal cost of the used metal cutting fluid.

By applying this machining technique, diseases caused by metal cutting fluid to the mechanist will be significantly reduced, therefore creating better lifestyles.

Hard turning is commonly carried out with advanced cutting tools such as ceramics, cubic boron nitride and polycrystalline cubic boron nitride to attain exceptional surface finish. However, the high cost of these tools necessitates exploration of alternative approaches. Therefore, this study investigates the potential of using cost-effective, multilayer-coated carbide tools under MQL conditions to achieve comparable surface quality.

The purpose of this study is to explore how changes in customer deposits influence the banking profits. The banking sector’s growth-promoting role is supported by its ability to perform the essential function of financial intermediation. However, Islamic banks go the extra mile by balancing the wealth of the rich and the poor and distributing risk more evenly. The effective operation of the services industry, including Islamic banks, depends on the active participation of their customers. Customers’ deposits in their accounts with Islamic banks are a crucial funding source. In actuality, two distinct sorts of demanding customers exist. Their expectations of the services provided by Islamic banks are different.

Panel quantile regression is applied using the collected data from Islamic banks’ audited financial statements for the time period from 2001 to 2021.

This study is expected to provide the breakdown of shares of current and saving deposits for Islamic banks, which supports managing liquidity risk. This breakdown will help the policymakers lay down a framework for managing the share of current and saving deposits in their favor.

The study aims to empirically evaluate whether changes in the current and saving account patronization have a role in the liquidity risk. And determine how banks need to manage their deposit structure to manage liquidity.

Previous studies have been nose-dive in providing country-level comparisons of different types of deposits in the context of liquidity risk management.

This study aims to develop a comprehensive sustainability performance index tailored for Takaful operators. It integrates Maqasid Al-Shariah’s principles with key stakeholders’ expectations, ensuring a holistic evaluation of sustainability practices.

The index is formulated through a multi-step process, beginning with a thorough literature review to identify pertinent economic, social, environmental and religious indicators. Using a Multi-Attribute Utility Theory approach, the process incorporates expert consultations, stakeholder workshops and the analytical hierarchy process. The framework amalgamates diverse sustainability attributes, focusing on regulatory compliance, financial performance, customer satisfaction, workplace environment and community engagement. The final index is tested with data from various Takaful operators to validate its reliability and robustness.

The newly developed index effectively captures the multifaceted aspects of sustainability specific to Takaful operators, offering a balanced assessment across economic, social, environmental and religious dimensions. Findings suggest that while Takaful operators excel in community welfare and ethical compliance areas, there are notable gaps in integrating environmental and social governance factors. The index successfully highlights these gaps, providing a structured framework to enhance the sustainability practices of Takaful operators. Initial applications of the index reveal significant variability in sustainability performance among Takaful operators, pointing to areas needing improvement.

The development of the index is limited by the availability and quality of data from Takaful operators. Future research should aim to improve data collection methods and expand the index’s application to a broader range of operators.

Takaful operators can use the index as a transparent and objective tool to evaluate and improve their sustainability practices, facilitating better decision-making and strategic planning towards achieving sustainable development goals.

By incorporating Maqasid Al-Shariah and stakeholder perspectives, the index promotes socially responsible and ethically sound business practices within the Takaful industry, aligning with broader societal values and expectations.

This paper introduces the first comprehensive sustainability performance index specifically designed for Takaful operators, integrating religious principles with conventional sustainability metrics. The index provides substantial value for researchers, practitioners and policymakers dedicated to enhancing sustainability in the Islamic finance sector.

This study aims to examine the Shariah non-compliance (SNC) disclosure index for all 16 Malaysian Islamic banks from 2015 to 2020.

A qualitative research methodology was adopted that included content analysis. The data were gathered from banks’ annual reports from 2015 to 2020. To achieve this, firstly, the disclosure index was developed by examining the disclosure requirements of the regulator and previous studies. The index was then used to measure the level of disclosure index for all these banks.

The overall average SNC disclosure index for the Islamic banks from 2015 to 2020 remained low at 0.57. However, the values were comprised of mandatory and voluntary items. For the former, the SNC disclosure index was quite high at 0.82, but for the voluntary items, the value was 0.40. Progressive improvement can be observed in the disclosure practices of the majority of the Islamic banks between 2015 and 2020; nevertheless, certain banks displayed a deterioration in their disclosure practices.

This study has several limitations, including the index used, the research period and the fact that it was restricted to SNC events.

These findings add value for information users by assuring them of the accountability of Islamic banks in terms of transparency, as well as their effectiveness in managing and mitigating SNC events. Regular monitoring and strong enforcement by the regulator are essential to achieve full compliance with the stipulated requirements.

This study offers a disclosure index for analysing SNC events in depth by segregating the disclosure into mandatory and voluntary items for each Islamic bank and making recommendations for future research. In addition, it provides a broad overview of current trends in SNC and the associated issues, as well as insights for regulators and the public in terms of the transparency levels of Islamic banks in relation to SNC event disclosure.

This study aims to perform a bibliometric and systematic literature review (SLR) to elucidate the current landscape and to propose a framework that defines and explores research strands to guide the formulation of business process management (BPM) strategies anchored in digital innovations.

This study explores distinct capital structure patterns between private and public companies, examining the varying influence of determinants on debt choices contingent upon a firm’s existing debt position.

Employing annual data from 2012 to 2022 for 142 public firms and 660 private firms in a large emerging economy, we use quantile regression within a panel data framework to study the heterogeneous effects of debt determinants, incorporating firm and time random effects.

Our findings indicate that such factors as size and operating margin contribute to higher levels of debt, while investment opportunities reduce the debt level. Further analyses, when accounting for a firm’s likelihood of being publicly traded, reveal that dividend payout and operating margin significantly influence debt levels, exclusively in the presence of high debt proportions. Conversely, investment opportunities emerge as a substantial determinant in all debt scenarios. In addition, we found a strong persistence in the indebtedness of companies, and we conclude that the effect of the determinants of indebtedness is heterogeneous according to the level of debt of companies.

This research provides a comprehensive comparison between private and public firms, not only in terms of debt levels but also in key capital structure determinants, highlighting their significance within the context of varying debt levels.
