The stringency policy and economic support policy in response to and to address the coronavirus disease 2019 have become a significant concern since the end of 2019. The motivation that led to this study is that, the selection of the stringency policy and the economic support policy appear to have brought about the opposite effects of the environmental costs of carbon dioxide emissions. The study's objective is to examine the contradictory impacts of these stringency and economic support policies on carbon dioxide emissions.

This study applies panel data for the top four countries responsible for carbon dioxide emission, namely China, the United States of America, India and Russia. A fully modified ordinary least squares estimator and dynamic ordinary least squares estimator are employed to determine the long-run parameters.

The results indicate that the effect of reduced carbon dioxide emissions due to a one-unit increase in the stringency policy is greater than the effect of increased carbon dioxide emissions caused by a one-unit increase in the economic support policy. Hence, if the two policies are implemented simultaneously, a positive net effect on environmental costs will be gained.

The study investigates in a general scope, the impact these response policies have on the environment. Future researchers may enhance the research on environmental impact in different sectors due to the implementation of both policies to enrich the analytical perspective.

The results have provided implications for policymakers to emphasize more on stringency-oriented policies while giving economic support to the low-income or unemployed households in order to reduce carbon dioxide emissions.

Despite the foreseen effects of the stringency policy and economic support policy, there has hardly been any studies that have explored empirically the nexus between both policies with carbon dioxide emissions in one empirical model. Furthermore, the paper uses the high-frequency data in determining the contradictory impacts of stringency policy and economic support policy on CO₂ emissions.

The commonly used e-procurement systems still show unsatisfactory implementation outcomes because many organisations are still unable to effectively interpret the initial adoption decision. The e-procurement systems are generally developed at organisational level, but their usage is at individual level, by the employees particularly. This paper examined technology acceptance model’s (TAM) key antecedents, involving e-procurement systems usage by employees in their daily activities. This study aims to examine the impact of factors affecting e-procurement acceptance among users through the mediating role of users’ attitude. The commonly used e-procurement systems still show.

TAM was applied and expanded in this study, in exploring the factors impacting the employees’ e-procurement acceptance. This study used quantitative method, and questionnaires were distributed to 200 users in Jordanian public shareholding firms. The collected data were quantitatively analysed using PLS modelling.

Significant TAM relationships involving e-procurement were affirmed. The expanded TAM in the scrutiny of antecedents showed that content, processing and usability affected perceived usefulness, while perceived convenience did not affect the usefulness factor. Furthermore, it was noticed that perceived ease of use was affected by usability and training, while perceived connectedness was not affected by usability and training.

The results demonstrated the necessity of e-procurement training. Furthermore, at the start of the implementation stage, effective design on system navigation and system usability, and consistent support, could increase use effectiveness and acceptance. Also, expedient information and buyer–supplier product flows should be made available.

Most organizations invest a lot of time and money in installing e-procurement systems to deliver their goods at the right time and at the right price. However, many of these e-procurement systems have failed due to low acceptance among users. Thus, to the best of the authors’ knowledge, this is the first study that used TAM and theory of planned behaviour in examining the effects of perceived convenience, perceived connectedness, content, training, processing and usability factors, in Jordanian firms. Lastly, the focus of this study was on the individual employee’s acceptance, rather than on the organisational-level adoption, as the unit of analysis, to provide insight on how organisations can achieve maximally from e-procurement investments and from other comparable technologies of e-supply chain management.

While an increasing number of investors value socially responsible investment practices, Bitcoin has faced criticism for its carbon footprint resulting from excessive mining power consumption. By examining Bitcoin’s interconnectedness with environmental, social and governance (ESG) equities, this study aims to construct a socially responsible investment strategy for cypto investors.

This study uses wavelet analysis and a time-varying parameter vector autoregressive (TVP-VAR) model to uncover the interdependence between ESG equities and Bitcoin. This study computes the optimal ratio, showing that Bitcoin significantly reduces portfolio risk when combined with green stocks.

The results show that co-movements between green stocks and Bitcoin are low, indicating that they are suitable combinations for portfolio diversification. From an environmental perspective, this investment strategy offers a theoretical solution to mitigate the negative impacts associated with Bitcoin mining. It aims to address the dilemma faced by sustainability-conscious investors, who must navigate the economic payoff of Bitcoin against their commitment to green investment principles.

The findings can provide valuable insights for policymakers seeking to develop strategies that promote sustainable investments among crypto investors.

Research on ethical investment practices in the cryptocurrency market remains in the early stages of development. Ethical investors can benefit from including Bitcoin in their ESG equity portfolios.

This study aims to investigate the practice of bay’ ‘inah contract in personal and home financing products by some Islamic Finance Institutions (IFIs) and examine the differences in the selection of contracts in banking products amongst IFIs mainly involving personal financing. The study will also propose a solution to the problem of differences and simultaneously standardise personal financing contracts in Malaysia.

The methodology of this study is qualitative, in which the data are collected through library research and field studies. The library research is done by examining books of usul al-fiqh (principles of Islamic jurisprudence), mura’aht al-khilaf, maqasid shariah (objectives of Islamic law) articles, statutes and related circulars, while field studies are conducted in an unstructured interview method with some members of Shariah Advisory Council (SAC) and academicians from Bank Negara Malaysia (BNM), IFIs and public university.

The findings show that there is a difference in views amongst SAC members in IFIs on bay’ ‘inah contract that effects the differences in the execution of such contract in banking applications. The study found that the bay’ ‘inah contract was non Shariah (Islamic law) compliant based on Shariah’s arguments and the opinion of the majority of past and present Islamic scholars. The study found that the BNM’s SAC did not allow the bay’ ‘inah contract to be practiced in personal and home financing products. Hence, this study proposes standardisation steps based on differences in the problems studied. The study also suggested that the SAC of BNM make improvements and updates on its solution regarding the bay’ ‘inah contract so that it is not misunderstood especially amongst IFIs.

The study is only looking at one case study, which is the bay’ ‘inah contract practiced by the IFIs in Malaysia.

This study proposes the standardisation of personal financing products practiced by the IFIs. The results of this study can reduce Sharīʿah non-compliance products in the market. The results of this study have gained a deep understanding of the solution of bay’ ‘inah contract made by the SAC of BNM. The findings also reduce the conflict between Shariah scholars locally and internationally and can restore the image of Islamic banking in Malaysia from engaging with controversy products or contracts.

The confidence of the public in Islamic banking is increasing as there is no contractual engagement with serious controversial issues and contracts similar to the concept of riba and hilah (trick) that is prohibited by Islamic law in IFIs.

This study analyses the differences of fatwa (a ruling on the point of Islamic law) about bay’ ‘inah contract decided by some SACs of IFI based on the discipline of usul al-fiqh. The study found that the bay’ ‘inah contract is not allowed by Islamic law. The study has proposed the standardisation of the fatwa differences based on the concept of mura’aht al-khilaf and the concept of standardisation in Islamic finance and to standardise personal financing products amongst IFIs in Malaysia.

This study explores the relationship between age and job satisfaction among Kuwaiti women employees in the Kuwaiti public government sector. The analysis is focused on the responses of the female employees to their own jobs as indicated by their level of job satisfaction. This study differs from previous investigations of job satisfaction in two principle ways: in dealing with the public sector (rather than the more common private in studies of the Middle East), in taking into account demographic variable such as age. The major findings of this research indicate that a much broader approach towards increasing satisfaction than focusing on the job itself is required.

The study evaluates the effects of GVC participation on firm productivity and profitability. Hence this study aims to find evidence whether there is a clear difference between the productivity and profitability effects of simple and complex backward and forward participations for Turkish firms.

The authors employ a firm level data from the Türkiye's both first and second top 500 industrial enterprises from 1993 to 2019. In addition, the authors calculate country-sector level both backward and forward GVC participation indices with their simple and complex sub-indices for each year from 1990 to 2015 from the Full Eora data of the Eora Global Supply Chain Database. The authors estimate the model with OLS and fixed effects. To understand the role of the 2008 global crisis, the authors also undertake estimations for the pre-crisis and post-crisis. The authors also divide the data by R&D intensity of sectors.

While backward GVC participation lowers both labor productivity and profitability growth, forward GVC participation promotes both. Moreover, simple and complex backward participation have similarly negative effects on productivity and profitability growth, simple and complex forward participation have the completely opposite effects though. The authors then provide substantial evidence for the differing effects of participation on productivity and profitability growth between pre-crisis and post-crisis periods. Interestingly, backward participation has a negative impact for both hi-tech and low-tech firms while forward participation boosts the productivity growth only for low-tech firms, probably due to the relatively more upstream position of low-tech firms.

To the best of the knowledge, no previous study has yet examined the profitability effects of GVC for firms. Second, in addition to overall backward and forward GVC participation rates, the authors also calculate and utilize simple and complex GVC measures in the estimations. Third, to reveal whether the global financial crisis leads to a shift in the productivity and profitability effects of GVCs, the authors separately run the regressions for the pre- and post-crisis periods. Fourth, the authors then investigate the argument that hi-tech sectors/firms could benefit more from joining GVCs compared to firms in low-tech technology sectors.

The purpose of this paper is to investigate the global influence of crude and refined oil futures prices on Dow Jones Islamic equity indices (DJIMI) during the recent global financial crisis under structural breaks in the conditional volatility of oil futures prices.

It aims at exploring the long-run and the short-run elasticity and causal relationships using an ARDL bound testing approach and a vector error correction model.

The main findings confirm the presence of long-run relationship for DJIM emerging markets index compared to other global and sub-regional developed indexes. Speed of adjustment to the long-run equilibrium is moderate and the effect of structural breaks, produced from nonlinear volatility model with long memory (LM), is overall not pronounced for that relationship. Short-run causality is bi-directional but long-run Granger causality does not run from refined oil to the DJIMI and crude oil.

The paper demonstrates the implicit extent of international financial integration of Islamic stock markets in light of the global influence of oil prices.

The findings offer some highlights to researchers, portfolio managers and policymakers.

The paper gives an answer to an identified need to test the position of Islamic equity markets as booming Islamic investment and socially responsible investment areas to the global influence of the new soaring path of oil markets. It uses as well bounds testing approach and tests weak and strong causalities under structural breaks. It considers as well LM behavior in oil prices along with the asymmetry property in oil prices.

The research objectives are as follows: to understand the situation of solid waste management in the Makham Tia Subdistrict Administrative Organization, Surat Thani Province, Thailand; identify the patterns in household waste generation and 3Rs behavior (recycle, reuse and reduce waste); and formulate sustainable municipal solid waste management guidelines.

This study aimed to propose the solution by using data analysis and a participatory research approach to set the guidelines for sustainable community waste management in a low-budget area. A survey of household behavior was done with questionnaires. Mixed clustering using the Gower coefficient was performed to assess the categorical socio-demographic variables along with the numeric variables related to the 3Rs behavior. The guidelines for waste management were generated based on the characteristics of the household groups.

The guidelines for waste management were generated based on the characteristics of the household groups. An appropriate practical plan for municipal solid waste management in Makham Tia Subdistrict was proposed in this work.
