Following a crucial COVID-19 pandemic lockdown, the coronavirus has affected every academic institution, particularly libraries and information centres. To address this unprecedented scenario, libraries’ staff has decided to provide their services via digital access while staying close to the users. To predict users’ intention to use digital libraries after COVID-19, the authors combined the technology acceptance model (TAM), the theory of planned behaviour (TPB) and perceived risk.

Data were collected via a paper-based questionnaire using a convenient sampling method which was distributed at two major libraries; Maulana Azad Library, Aligarh Muslim University and Dr Zakir Husain Library, Jamia Millia Islamia in India.

Empirical findings suggested that all the proposed hypotheses were supported, and the integrated model had strong explanation power as the proposed model explained a 74.5% variance in users’ intention to use digital libraries after COVID-19.

This study offers substantial information to librarians, digital libraries, universities, institutes and other stakeholders and sheds light on the potential for a developing nation to transition to an economy with a strong digital infrastructure. The scope of the study is constrained to the users in India only, hence, leading to the possibility that it may be challenging to generalize the findings.

According to the best of the authors’ knowledge, it is one of the few studies to predict users’ intentions for using digital libraries after COVID-19 by applying the integrated model of TPB and TAM in an emerging economy. It helped understand the users’ attitudes towards using the digital services and resources available at the respective libraries. It also contributed considerably to the argument that users have grown accustomed to harnessing digital libraries during the post-COVID-19 period.

The paper answers the following questions: (1) Do firms located in rural areas experience greater problems in accessing financial services? (2) If this is the case, what can these firms do to improve their access to finance?

This paper uses the pooled logistic regression and the data collected by the World Bank's Enterprise Surveys during the period between 2008 and 2018 to answer the aforementioned questions.

The results of this paper show that firms headquartered in rural (urban) areas experience greater (lower) problems in accessing finance than other firms. This paper attributes these findings to higher (lower) levels of information asymmetry and lower (higher) levels of density of banking operations in rural (urban) areas. The results of this paper also show that firms headquartered in rural areas can improve their access to finance by increasing the skill levels of their employees.

This paper highlights the actions that rural firms can undertake to overcome the adverse impact of their geographic location.

Zakat, one of the fundamental pillars of Islam, holds the potential to significantly contribute to fiscal consolidation, particularly in developing nations. However, the national-level potential of Zakat often remains unexplored. This study aims to explore the potential of national-level Zakat and the opportunity to integrate it into the fiscal framework.

This study estimates Zakat’s potential on national financial and economic components. The components include bank deposits, shares and securities, pensions (provident fund), industrial production and trade services, mining resources, Ushr on agro-crops and forestry, Ushr on livestock, Ushr on fishery, gross domestic product (GDP), national budget and national revenue. The study gathers data, ranging from FY2000 to FY2018, on national economic sectors from reliable secondary sources. The net value (NV) of each indicator is calculated as NV = TV − LA, where NV is the wage-adjusted net value after deducting the living adjustment (LA) value from the sectoral total. The proposed LA value, approximately 20%, is suggested to be deducted from the total sectoral value of each sector (excluding specific industries with preadjusted wages), equating to the Nisab value.

It is estimated that the aggregate potential of Zakat in Bangladesh was US$9,749m in FY2018, compared to US$809m in FY2000, revealing the value is 3.77% of GDP and 21% of the national fiscal budget. In FY2018, the service sector was the largest contributor (30%), followed by bank deposits (23%). Pension funds made minimal contributions, whereas shares and bonds, as well as the manufacturing sector, each made a 10% contribution to the estimated Zakat potential. Zakat on agriculture output accounted for 15% of the total. The aggregate potential Zakat in FY2018 was 12% higher than that in FY2000.

The paper highlights a novel contribution through its nuanced analysis of sector-specific Zakat on macrolevel data and its implications within the fiscal framework. The results suggest that Zakat has substantial potential to impact fiscal dynamics, providing valuable insights for policymakers and stakeholders to recognize the national-level Zakat for development plans such as the five-year plan. The study suggests piloting a central and independent national body to study the feasibility of national-level Zakat collection and its utilization in the fiscal budget. It will help the government reduce the burden of external debt and deficit budget and, instead, will promote revenue collection in collaboration with the National Board of Revenue.

The influence of some N‐containing organic compounds such as tetraethanol‐β‐octadecenyl succinylamide (TOSA), morphonil‐β‐hexenyl succinylamide (MHSA), ammonium naphthenyltri‐n‐butyl chloride (ANBC) and 1‐(2,4,6‐trimethylphenyl)‐3‐diethylaminopropanol‐2 (TMAP) as inhibitors for the corrosion of carbonized steel in mineral acid (HCl and H₂SO₄) solutions with different concentrations has been studied by using gravimetrical, electrochemical and polarization corrosion test methods. Observes that all compounds having surface active properties behave as inhibitors of a functional active cathodic type and have an inhibition effect at the first stage of corrosion in both acids, but more effectively in H₂SO₄. Shows that inhibition effect increases with increase of temperature in 0.5N H₂SO₄ solution and decreases with increase of temperature for the higher concentrations of acidic solutions. Shows that TOSA and TMAP compared with MHSA and ANBC enchance protection properties of adsorption layer.

In a globalized environment, small and medium enterprises (SMEs) are facing formidable challenges. Not only do they have to keep up their profitability, but there is also a pressure from various stakeholders to add to their environmental and quality performance .The solution obviously lies in continuously adopting and improving upon lean-green practices in their operations. This work aims at identifying, classifying and building up a duly tested robust ranked-order model of such “enablers”, related to lean-green practices, that puts them (the enablers) in an order of being the most significant to being the least significant further to be accorded the same or similar weight in strategy formulation and implementation stage by Indian SMEs for enhancing their overall organizational performance.

The study identifies 20 enablers (12 lean and 08 green manufacturing enablers) through extensive literature review and experts' opinion survey and classifies them into three main categories. The ranking and significance of each of the main and subcategory enablers is evaluated according to its weight which is determined by the best-worst method (BWM) approach, one of the novel multi-criteria decision-making (MCDM) methods. Further, the results have been drawn after running accuracy check of the rankings (based upon optimal weights) and testing the robustness of the ranked-order model through sensitivity analysis.

The results of this study reveal that out of the three main category enablers, “operational performance enablers (E1)” and “quality performance enablers (E3)” are the most and the least significant enablers, while in the group of 20 subcategory enablers, “Kaizen (E17)” and “environment emission control (E28)” are the most and the least significant subcategory enablers, respectively.

The prioritization model or ranked-order model of the lean-green manufacturing enablers proposed through this study may serve as a standard model to managers to help them decide and allocate their efforts and resources accordingly in managing their operations. This will also help them adopt high-ranking lean-green manufacturing enablers in their firms and benchmark and standardize their existing practices accordingly, leading to greater competitive advantage.

The study identifies various green-lean manufacturing enablers in SMEs, classifies them into three main categories and ranks them using BWM approach. The findings of this study should be extremely relevant to managers, manufacturing engineers and practitioners in Indian SMEs from the perspective of developing deeper appreciation of these enablers as per their relative ranked importance to further formulating an effective and efficient strategy for their implementation resulting in optimal results.

This paper briefly introduces the concept of model selection, reviews recent development in the area of econometric analysis of model selection and addresses some of the crucial issues that are being faced by researchers in their routine research problems. The paper emphasizes on the importance of model selection, particularly the information criteria and penalty functions based model selection procedures which are useful for economists and finance researchers.

The purpose of this paper is to cover some aspects about the disposal and regulatory standard around the world toward hospital effluent discharge, its managements and treatment technologies that are adopted and best suitable nowadays.

Due to large and variety of antibiotics available in the market nowadays it is difficult to control its use, thereby risking the whole ecosystem and its components. The regulation pattern is variable depending upon the various factors in different countries. The permissible limit of these emerging pollutants found in sewage as compared to in hospital effluent streams having active pharmaceutical ingredients is very narrow and is a debatable issue.

The disparity in the available legislation for hospital waste management in different countries makes it difficult to compare pro’s and con’s of methods adopted. Strict laws need to be framed for hospital wastewater management and its treatment, as it contains harmful compounds in higher concentrations resulting in development of resistant genes. The guideline applicable nowadays makes it clear that, specific management guidelines with respect to HWW, but also indicate certain characteristics that can be represented to specify their nature and indicator.

Determination of effluent characteristic for each specialized treatment need to be analyzed for meeting the framed regulatory standards. Up-gradation of existing treatment facilities, adopting new technologies and improving operation, maintained is a viable option. As there are no specific treatment schemes available hence combination and optimization of treatment methods may solve the problem to certain extent.

There is some flexibility also there so that law framework can be modified accordingly. For any health facilities direct discharges into natural water bodies it effluent need to follow national discharge standards. These are quite strict as compared to indirect standards and generally not meet by such facilities. This is quite logical because they are not being monitored or treated by municipal systems.

The law indicates that hospital needed to collect and treat effluent according to the treatment standards. But on other hand the law was made making it consideration about the HWW collection in water bodies.

The best way of management as described, is to treat HWW onsite-dividing into primary, secondary and tertiary. The document also provides details about sludge disposal, possible reuse, including the application of new and innovative treatment technologies for HWW. It also provides guidance for minimum approach for HWW management because developing countries patients do not have proper sanitation facilities.

The link between supply chain agility (SCA) and performance has been tested in previous research with different samples and results. The present paper quantitatively analyses and summarises the impact of SCA on performance found in previous empirical papers and determines the influence of several identified moderators.

Using a meta-analysis approach based on a systematic literature review, a total of 63 empirical papers comprising a sample of 14,469 firms were meta-analysed to consider substantive (type of performance and SCA operationalisation) and extrinsic (economic region and industry) moderators.

Results confirm a significantly large, positive correlation between SCA and performance. None of the analysed moderators has enabled the identification of any significant differences between the SCA and performance correlations by subgroup. However, high heterogeneity in total variance, both in the full sample and the subgroups by moderator, demands further rigorously reported empirical research on this topic with clearly conceptualised variables and frameworks and the use of validated scales.

Several research gaps and best practice recommendations have been indicated to improve future empirical research on this topic.

Practitioners in different economic regions and industries will find consistent evidence of improvements in performance through SCA.

No meta-analysis has been found in previous research to estimate the value of the correlation between SCA and performance and the influence of moderating variables.

The purpose of this paper is to present an analytical justification from statistical view point about why Islam has strictly forbidden interest for the humankind.

It is a theoretical paper that looks into analytical views of justification in order to investigate the motivation of prohibiting interest.

The results of the paper suggest that interest has a great negative impact on the society, economy and morality of human beings. Analysis found some solid reasons which proved that interest has been really an evil system for the humankind and society as a whole for all times in the history of civilizations. On the other hand, from the statistical information given in the paper it was found that interest‐free financial institutions have been very successful in terms of their deposit, investment, foreign exchange business, financial stability and popularity as compared to the interest based financial institutions.

The impact of interest‐free financial institutions in development financing and in establishing sustainability of a welfare community remains a potential problem due to our shortage and/or lack of proper knowledge.

It is, therefore, very important to be aware of the exact stance of Islam on interest first. Then more extensive networking and complementary relations are needed among the financial and socio‐economic development goals in accordance with the tenets of the Islamic Shariah.

The paper shows its originality in substance and makes a unique contribution to the literature on systems and ethics.
