Incorporating blockchain into Halal traceability systems is developing in nature; the research aspires to examine the participation intent in blockchain-empowered Halal fashion traceability (BHFT) system via a joint framework that includes diffusion of innovation theory, institutional theory, and Halal-oriented approach. The study uses a simple random sampling method to collect the data from 165 Indonesian Halal fashion manufacturing companies. PLS-SEM is employed to examine the conceptual framework. Findings show that Halal-oriented approach significantly affects institutional pressures, while institutional pressures significantly affects perceived desirability, and perceived desirability significantly affects the participation intent. The companies operating an inclusive Halal-oriented approach will be more aware of the institutional pressures that expect them to partake in a BHFT. The paper enhances the existing literature in Halal supply chains, blockchain, operation management, and information systems via a cohesive framework and empirical insight.

“Curse of dimensionality” has become the major challenge for existing high-sigma yield analysis methods. In this article, we develop a meta-model using Low-Rank Tensor Approximation (LRTA) to substitute expensive SPICE simulation. The polynomial degree of our LRTA model grows linearly with the circuit dimension. This makes it especially promising for high-dimensional circuit problems. Our LRTA meta-model is solved efficiently with a robust greedy algorithm and calibrated iteratively with a bootstrap-assisted adaptive sampling method. We also develop a novel global sensitivity analysis approach to generate a reduced LRTA meta-model which is more compact. It further accelerates the procedure of model calibration and yield estimation. Experiments on memory and analog circuits validate that the proposed LRTA method outperforms other state-of-the-art approaches in terms of accuracy and efficiency.

This study aimed to investigate English as a second language (ESL) undergraduates’ sociocultural perspective of willingness to communicate (WTC) in English inside the classroom in relation to language use outside the classroom. The participants were 440 ESL undergraduates selected through the cluster sampling method from eight universities in Khyber Pakhtunkhwa Province in Pakistan. The data were collected through questionnaires on WTC in English inside the classroom and language use outside the classroom. The findings revealed that the participants’ level of WTC in English was high for most social interactions within the classroom, such as in groups, during activities, with the same gender, and when given preparation time in groups. The findings for language use showed that a mixture of languages, such as Pashto and Urdu, was predominantly used in the family, neighbourhood and friendship, religion, education, and transaction domains. In contrast, English was primarily used in the mass media and social media domains. Moreover, the findings revealed that WTC in English inside the classroom was positively correlated with social media, mass media, transaction and education domains but negatively correlated with the family domain.

The purpose of this study is to find out whether the effect of Market Value Added, Profitability, and Market Value Added on stock price. Sampling in this study is a purposive sampling method. Then the data is tested using multiple regression analysis. The results of the t test showed that the Economic Value Added has a signification value of 0,018 which means smaller than 0,05 and the calculated value of -2.441<t tablel 2.00758 then H1 is accepted. Profitability has a signification value of 0,034 greater than 0,05 and a calculated value of 2.182>t table 2.00758 then H2 is accepted, Market Value Added has significant  value of 0,223 greater than 0,05 and the value of t calculated -1.235<t table 2.00758 then H3 is rejected. The results of the F test showed that Economic Value Added, Profitability, Market Value Added have a calculated F value of 2,933 and sig. 0,042. Because the value F calculated 2.933>F table 2.773 and sig. value 0,042<0,05. It can be concluded that partially Economic Value Added has a significant negative effect on stock price, Profitability has a significant effect on stock price, Market Value Added has no significant effect on stock price and simultaneously Economic Value Added, Profitability, Market Value Added has a significant effect on stock price Keywords: Economic Value Added, Profitabilitas, Market Value Added, Stock Price

The purpose of this research is to provide empirical evidence about the effect of operating cash flow, sales volatility, cash flow volatility, operating cycle, and book tax difference on earnings persistence. The company used in this research is manufacturing company listed in Indonesia Stock Exchange (IDX) from 2016 until 2020. Samples of this research were selected based on the purposive sampling method and resulted in 43 companies, therefore the data used for this research amounting to 215 data. The data obtained from these samples were analyzed using multiple regression method. The result of this research show that operating cycle have influence on earnings persistence. While operating cash flow, sales volatility, cash flow volatility, and book tax difference have no influence on earnings persistence.

This study aims to determine whether there is an effect of Capital Adequacy Ratio (CAR), Non Performing Loan (NPL) on Profitability (ROA) with Efficiency (BOPO) as an Intervening Variable, in conventional commercial banks in Indonesia listed on the Indonesia Stock Exchange period (2016). -2020). Sampling using the purposive sampling method with the criteria that the bank has a complete published report in 2016-2020, and the bank has a non-negative ROA. This study uses data obtained from the bank's Annual Financial Statements issued by the bank in the Financial Services Authority (OJK) Bank Published Financial Statements. The analytical technique used is a statistical test through the Ttest, Ftest, R2, Multiple Regression Test, and Sobel Test using the Sobel Test Calculator for the Significance of Mediation. The results of the analysis on the t test show that CAR has a negative and insignificant effect on ROA, NPL has a negative and insignificant effect on ROA, BOPO has a negative and significant effect on ROA. CAR has a negative and significant effect on BOPO, NPL has no significant effect on BOPO. And the results of the Sobel test showed that BOPO was able to mediate the CAR variable on ROA but was unable to mediate the effect of NPL on ROA. Keywords: CAR; NPL; ROA; BOPO

The current research aims to identify the level of fear of Covid-19 and loneliness among Yemeni students in China, and to determine the relationship between them and whether there are differences in the responses of the research sample according to gender. The research adopted the descriptive approach, and the questionnaire was used as a tool for collecting data from the research sample. The research community consisted of Yemeni students in China who were enrolled in the 2021 academic year, the sample is (301) male and female students who were selected using a simple random sampling method. The results showed that the level of fear of Covid-19 and the degree of loneliness were high. There is a positive relationship between fear of COVID-19 and loneliness. There are differences in fear of Covid-19 according to the gender variable in favor of males, and differences in loneliness in favor of females.
