To provide a finite volume code, based on Cartesian coordinates, for studying combined conductive and radiative heat transfer in three‐dimensional irregular geometries.

In the present study, a three‐dimensional blocked‐off‐region procedure was presented and implemented in a numerical code based on the finite volume method to model combined conductive and radiative heat transfer in complex geometries. This formulation was developed and tested in three‐dimensional complex enclosures with diffuse reflective surfaces and containing gray absorbing‐emitting and isotropically scattering medium. This approach was applied to analyze the effect of the main of thermoradiative parameters on the temperature and flux values for three‐dimensional L‐shaped enclosure.

The proposed isotropic model leads to satisfactory solutions with comparison to reference data, which entitles us to extend it to anisotropic diffusion cases or to non‐gray media. The blocked‐off‐region procedure traits both straight and curvilinear boundaries. For curved or inclined boundaries, a fine or a non‐uniform grid is needed.

This paper offers a simple Cartesian practical technique to study the combined conductive and radiative heat transfer in three‐dimensional complex enclosures with both straight and curvilinear boundaries.

The shift from physical class to online classes in the pandemic COVID-19 situation has posited opportunities as well as challenges for teachers and students. The primary purpose of this research is to investigate challenges faced and benefits availed by the teachers at the tertiary level in universities of Pakistan and Indonesia.

To achieve the purpose a mixed-method approach is employed to answer the three research questions of the present study. The quantitative data is obtained from the responses of 66 teachers, teaching online in Mehran UET Pakistan and 102 teachers from Indonesian university. The personal, technological, and pedagogical challenges were analyzed by descriptive statistics on SPSS. Thus, the independent-samples t-test was run to test for statistically significant differences faced by teachers in both countries.

The findings revealed that there were no statistically significant differences found in personal, and pedagogical challenges faced by both countries' teachers, whereas there is a significant difference in facing technological challenges between Pakistani and Indonesian teachers. The benefits of online teaching were investigated qualitatively by conducting semi-structured interviews with 10 teachers 5 from each country. There are very positive aspects of online teaching revealed in the interviews.

The paper includes implications for the development of Computer Assisted Language Learning, the development of technology integrated courses, and for managing the balance between physical and online classes.

The findings of the study have implications on finding out the solutions of the derived challenges, further it suggests to concentrate on students of public and private universities in Pakistan and Indonesia so that a comparison of challenges faced by teachers and faced by students can be researched and evaluated and it can generate significantly different results.

The implications on the research society and the teachers and designers' communities are very clear in this research because it paves the way forward towards the blending of technology in any way either synchronously/ asynchronously into education, further researches can be done on designing the new concepts, courses, instructional platforms for students and investigate the new dimensions and effects of them.

Findings have value, because two countries' context (developing countries) with respect to the comparison of the challenges and benefits is better understood, it would have different results if had done in the developed countries.

The purpose of this study is to explore how governance mechanisms (internal and external) enhance the performance of the return on asset (ROA), return on equity (ROE), earning per share (EPS) and dividend payout ratios (DP) of the banks of Pakistan. The study incorporates not only the internal factors of governance (board size, out-ratio, annual general meeting, managerial ownership, institutional ownership, block holder stock ownership and financial transparency) but also the external factors (legal infrastructure and protection of minority shareholders, and the market for corporate control).

The sample size of the study consists of 30 banks (public, private and specialized) listed at the Pakistan Stock Exchange (PSE) for the period 2008-2014. The panel data techniques (fixed or random effect model) have been used for the empirical analysis after verification by Hausman (1978) test.

The results revealed that not only do the internal mechanisms of governance enhance the performance of the banking sector of Pakistan but external governance also plays a substantial role in enriching the performance. The findings conclude that for a good governance structure, both internal and external mechanisms are equally important, to accelerate the performance of the banking sector.

Internal and external mechanisms of corporate governance can also be checked by adding some more variables (ownership i.e. foreign, female and family as internal and auditor as external), but they are not added in this work due to data unavailability.

The study contributes to the literature and could be useful for the policy makers who need to force banks to mandate codes of governance through which they can create an efficient board structure and augment the performance. The investments from different forms of ownership can be accelerated if they follow the codes properly.

The study facilitates the bankers in incorporating sound codes of corporate governance to enhance the performance of the banks.

This work is unique as no one has explored the impact of external mechanism of governance on the performance of the banking sector of Pakistan.

The development and commerce of functional foods (FF) is complex, expensive and risky. Besides technological obstacles and legislative aspects, consumer demands also need to be considered. The purpose of this study is to assess the Lebanese consumer’s knowledge, attitudes and acceptance of FF and functional ingredients.

A cross-sectional study recruited a convenience sample of adults living in Mount Lebanon in 2015. An interviewer-based questionnaire assessed socio-demographic factors, medical status, consumption and knowledge of FF and FI ingredients. The data were analyzed using statistical package for social sciences.

Out of 251 respondents, 40.6 and 32.0 per cent were knowledgeable about FF and FI, respectively, and 67.3 per cent consumed them. Calcium (48.0 per cent) and omega-3 (38.6 per cent) were identified as the most important FI. The consumption of FF was mainly owing to their nutritional benefits beyond basic nutrition (44.2 per cent); however, fearing artificial additives and their side effects (33.4 per cent) were reasons for rejecting them. FF knowledge was higher among young (p = 0.005) and single individuals (p = 0.002) and those going to the gym (p = 0.001), whereas willingness to learn about them was only associated with higher education (p < 0.001). Prebiotic yogurt consumption was higher among gym visitors (p = 0.017) and knowers of FF (p < 0.001). The consumption of protein bars and shakes was higher among males and those going to the gym (p < 0.001). The consumption of cereal bars was higher among young individuals, single, with high income, going to the gym and knowledgeable about FF (p < 0.05).

The findings are useful for market orientation, development and successfully negotiating new market opportunities of FF for both food industries and policymakers.

The paper examines the impact of financial statement comparability on cash holding moderated by Environmental Social Governance (ESG) performance.

A panel dataset of all publicly listed Indonesian firms from 2009 to 2022, evaluated with panel data regressions controlled by year and clustered by firms was the method of study. Then, a robustness test using alternative measurements, lagged variables and additional analyses are performed.

The result shows that there is no moderating role of ESG performance on financial statement comparability toward cash holding among Indonesian firms; nonetheless, ESG performance strengthened the capacity of financial statement comparability to lower cash holding significantly for firms with high ESG performance scores and not significant otherwise. This interplay of variables is developed following the Financial Services Authority imposed ESG regulation for publicly listed firms in Indonesia. Further, the analyses reveal that higher ESG performance can help firms achieve high market-based performance and make it easier to obtain external financing, thus lowering the need to hold more cash.

The study highlights the effect of financial statement comparability on cash holding, particularly moderated by ESG performance in a developing country where the agency cost is high and still very rare to be scrutinized. Additionally, the study helps to know the impacts prior and post-ESG regulation imposed in Indonesia.

This paper aims to fill a gap in the literature of marketing communication by exploring the role of different nudges implemented through advertising and personal selling in enhancing purchase intention and sales of mutual funds in Pakistan.

Data collected by 20 semi-structured individual qualitative interviews in Pakistan were subjected to thematic analysis.

This study reveals the way managers apply different nudges in the form of Islamic beliefs and values in advertising and personal selling to enhance purchase intention and sales of mutual fund products among Muslim customers. Nudges that can be used in marketing communication may include religious cues, religious beliefs, religious values, spiritual elements, halal aspects of investment plans, religious icons and symbols, cultural music and images, appropriateness and correctness of sales messages and communicating halal aspects of mutual funds.

The conclusions are based on findings from a relatively small number of respondents from one investment firm, but they offer an empirical basis for future research on the effect of advertising and personal selling on the sales and purchase intention of mutual fund products in an Islamic society.

This study offers practitioners a better understanding of the marketing communication tools likely to influence consumers’ purchase intention of mutual fund products, with positive implications in creating advertising and sales management in Pakistan.

Despite the prevalence of promoting mutual fund products, little research-based analysis has been available to academics or practitioners.

The increased concerns for the environment have led organizations, businesses and nations to act environmentally friendly. This has also pressurized the banking sector to adopt green practices. However, there is a dearth of studies related to green banking (G-banking) adoption practices (GBAP) on banking performance. Hence, by considering the resource-based view theory, this study aims to examine the impact of GBAP on banking performance, i.e. financial, operational and environmental performance.

The data was acquired from banking personnel in Pakistan using a five-point Likert scale questionnaire and a non-probability purposive selection technique. In total, 400 responses were gathered, on which data screening was performed to detect and delete outliers. On a useful sample of 360, partial least square-structural equation modeling was used to validate the hypotheses.

The findings revealed that GBAP positively affects the environmental, operational and financial performance of the banks. The findings further revealed that GBAP largely affects environmental performance followed by operational performance and financial performance, respectively.

The study findings offer various insights to the policymakers and the banking sector to better implement G-banking practices in improving banking performance.

To the best of the authors’ knowledge, this is one of the first studies to look at the effect of GBAP on key performance outcomes, i.e. financial and operational performance. This study also verifies the use of resource-based perspective theory in the context of G-banking.

The purpose of this study are: to study the difference between halal awareness and halal certified awareness, and the relationship between the two variables; to study the differences in knowledge about halal and halal certified, as well as their relationship with halal awareness and halal certified awareness; and to build and test research models regarding factors that affect certified halal awareness.

The target population is Muslims who live in Indonesia and are 18 years old or more. The self-administered survey method is carried out based on a purposive sampling technique. The authors collect data from 428 Muslim respondents in Indonesia through an online survey. This study applies the partial least square–structural equation model to examine causal relationships and test hypotheses.

This study reveals several results: halal awareness is a different concept from halal-certified awareness; knowledge of halal is a different concept from knowledge of halal certificates; awareness is an outcome of knowledge, but knowledge is not an outcome of awareness; halal awareness has a significant effect on halal-certified awareness; knowledge about halal certificates has a significant effect on halal-certified awareness, but knowledge about halal does not have a significant effect; knowledge of halal certificates is not influenced by knowledge of halal and halal awareness; and exposure and religious commitment have a significant role in increasing knowledge and awareness.

Research that explores the difference between halal awareness and halal certified awareness, and Muslim knowledge about halal and halal certified, especially in the context of halal-certified food, is still very limited in the literature provided, if not unavailable. Furthermore, this study also builds and tests research models regarding the factors that affect certified halal awareness, which is limited or may not have been found in the literature.
