This study was conducted to analyze the effects of machining parameters on the specific energy consumption in the computerized numerical control lathe turning operation of a hardened alloy steel roll at low cutting speeds. The aim was to minimize its consumption.

The design matrix was based on three variable factors at three levels. Response surface methodology was used for the analysis of experimental results. Optimization was carried out by using the desirability function and genetic algorithm. A multiple regression model was used for relationship build-up.

According to desirability function, genetic algorithm and multiple regression analysis, optimal machining parameters were cutting speed 40 m/min, feed 0.2 mm/rev and depth of cut 0.50 mm, which resulted in minimal specific energy consumption of 0.78, 0.772 and 0.78 kJ/mm³, respectively. Correlation analysis and multiple regression model found a quadratic relationship between specific energy consumption with power consumption and material removal rate.

In the past, many researchers have developed mathematical models for specific energy consumption, but these models were developed at high cutting speed, and a majority of the models were based on the material removal rate as the independent variable. This research work developed a mathematical model based on the machining parameters as an independent variable at low cutting speeds, for a new type of large-sized hardened alloy steel roll. A multiple regression model was developed to build a quadratic relationship of specific energy consumption with power consumption and material removal rate. This work has a practical application in hot rolling industry.

This research study investigates the factors that influence e-customer satisfaction, e-trust, perceived value and consumers repurchase intention in the context of the B2C e-commerce segment. It investigates the mediation effect of e-customer satisfaction, e-trust and perceived value on repurchase intention. It also examines the moderating role of prior online experience.

Based on the adapted questionnaire, pre-recruited enumerators collected the data from five leading business universities of Karachi. They distributed 425 questionnaires and received 415 questionnaires. The study has used Partial Least Square-Structure Equation Modeling (PLS-SEM) technique for data analysis.

We have tested 20 hypotheses, of which our results do not support five, including two direct, two mediating. Our results support all the direct hypotheses except the following two: (1) delivery service affects e-satisfaction (2) customer services quality effect on trust. We did not find support for the following two mediating hypotheses (1) e-satisfaction mediates delivery services and repurchase intention, (2) service quality mediates customers' service quality and repurchase intention. Our results do not support one moderating relationship. Prior online experience moderates e-perceived value and repurchase intention.

This research provides valuable information to the online retailers of B2C e-commerce, which can help them make strategies based on their consumers' behavior and encourage them to make repeat purchases from online retailing stores. It allows future researchers to replicate the model in cross-cultural studies in different product categories.

We have examined the moderating effect of prior online experience between (e-satisfaction, e-trust and perceived value) on the repurchase intention.

The purpose of this study is to analyze how to improve the satisfaction and loyalty of Badan Penyelenggara Jaminan Sosial Kesehatan (BPJS) health patients in Indonesia based on services in Islamic hospitals, where the service quality was analyzed from a Sharīʿah perspective.

The sample for this study was 470 Muslim patients from BPJS health, 248 from large Islamic hospitals and 232 from small Islamic hospitals in Central Java, Indonesia. Overall, the respondents were from five large hospitals and five small hospitals. The study used eight service quality variables that were modified from the SERVQUAL, PAKSERV and CARTER models. All the variables used indicators of Sharīʿah principles and tested their effects on satisfaction and loyalty.

The results of the study showed that the insurance system has been proven to significantly increase the satisfaction and loyalty of BPJS health patients. This means that the efforts of the Indonesian Government to improve the level of health by establishing BPJS can benefit the community. Satisfaction can also be increased through the variables of reliability, empathy and responsiveness, while the loyalty of BPJS Health patients is strongly influenced by satisfaction. The sincerity variable can increase the satisfaction and loyalty of BPJS health patients in small hospitals, but not in large hospitals. On the other hand, the variable of compliance can increase the satisfaction and loyalty of BPJS health patients in large hospitals, but not in small hospitals.

The insurance system implemented in Indonesia can influence the improvement of satisfaction and loyalty. Also, hospitals that are fair in serving patients and that apply amanah (trust), tabligh (responsiveness) and are fast in handling BPJS health patients’ complaints are important indicators that need attention from BPJS health and hospitals. These indicators can form variables that can increase satisfaction and loyalty.

Marketing scholars have begun to look at negative emotions that young consumers could develop toward brands, such as brand hate. Brand hate has experienced exponential growth during the past decades in the cosmetic industry. In this frame, the purpose of this paper is to identify the weight of each of the five key drivers of brand hate and to analyze if these weights are the same (or not) for drugstore and luxury make-up brands regarding.

To carry on this paper, brand haters in the make-up industry were contacted with the help of cosmetic influencers. Participants of the online questionnaire (N = 162) were existing young makeup consumers. They were divided into drugstore and luxury makeup brand haters by classifying their identified hated brands into either group.

The authors’ results showed, first, that experiential, identity, moral, deficit-value and advertising avoidance all had a positive effect on brand hate, being identity avoidance the strongest one. Second, drugstore and luxury makeup brand haters do not differ, as far as no differences were identified in the strength of each avoidance type on brand hate.

There is a gap in the literature related to the absence of work investigating brand hate in the make-up industry; moreover, studies measure whether brand hate drivers are the same (or not) for luxury brands and drugstore brands that compete in the same arena. In this framework, this research will provide a specific industry context involving young consumer opinions. Research into consumer–brand relationships has been largely focused on the positive forms, while the negative forms are still a relatively newer area of academic interest. Even more, brand hate has been investigated from a multidimensional approach linking proposals from different authors has been tested.

Sustainability is essential to the ongoing operations of banks, though it is much less clear how Islamic corporate governance (ICG) promotes economic sustainability (ES) and thereby prevents bankruptcy. To explore the unexplored, this study aims to examine the efficacy of ICG in preventing bankruptcy and enhancing the ES of Islamic banks operating in Pakistan.

The current study measures ES through Altman's Z-score to analyze the level of the industry's stability and consequently examines the effect of ICG on the ES of Islamic banks in Pakistan for the post-financial-crises period. Using the country-level data, this study utilized a fixed-effect model and two-stage least squares (2SLS) techniques on balanced panel data spanning from 2009 to 2020 to provide empirical evidence.

The empirical results unveiled that board size and meetings have a significant positive influence on the ES while managerial ownership demonstrated an unfavorable effect on ES. Interestingly, the insignificant effect of women directors became significant with the inclusion of controlled variables. Overall, the findings indicate that ICG is an efficient tool for promoting ES in Islamic banks and preventing them from the negative effects of emerging crises.

The findings provide concrete insights for policymakers, regulators and other concerned stakeholders to execute a sturdy corporate governance system that not only oversees the economic, social and ethical aspects but also provides measures to alleviate the impacts of potential risks like the COVID-19 pandemic.

Examining the role of ICG in alleviating bankruptcy risk is an informative and useful endeavor for all social actors.

To the best of the authors’ knowledge, this study is one of the first efforts to provide evidence-based insights on the role of ICG in preventing bankruptcy and offers a potential research direction for ES.

Service quality is an established research area in the services marketing literature and is an integral component in an Islamic economy driven by halal service sectors. Despite its importance and the rapidly changing service environment, there has yet to be a comprehensive study of service quality research across halal industries. The purpose of this study is to systematically review the existing literature on service quality in halal industries to provide a state-of-the-art understanding and identify opportunities in this research area.

Guided by the Scientific Procedures and Rationales for Systematic Literature Reviews (SPAR-4-SLR) protocol and the theories, contexts, characteristics and methods (TCCM) framework, this paper reviews 78 journal articles from the Web of Science database which features service quality as an underpinning theory in the context of halal economies.

Findings indicate that since the first study in 2010, service quality research in halal industries has concentrated on consumers in the Islamic finance sector who are served primarily by human service agents. Most studies are focused on halal industries in Muslim countries. Several papers adopt the SERVQUAL model while others develop more novel service quality scales for halal industries. Culture, technology and faith-related factors are key drivers of halal service quality. While few papers study the antecedents and moderators of service quality in halal industries, religiosity was found to be a significant variable in several papers reviewed.

The global Islamic economy will continue to be driven by halal services. This review will provide managers with an appreciation of service quality across different halal industries. Researchers can use the results of this review to guide future studies and contribute toward the development of this research area.

To the best of the author’s knowledge, this paper is the first to comprehensively map the antecedents, dimensions, outcomes and moderators of service quality across halal industries and provides managers with a strategic understanding of service quality across the halal economy. This study develops a conceptual model and concludes with a research agenda to advance halal service quality research.

The purpose of this study is to identify the factors that were considered important by Muslim BPJS participants of service quality received when using BPJS Health card for hospitalization services.

The sample consisted of 250 respondents that came from five hospitals in Indonesia. The variables used in this study modify SERVQUAL, PAKSERV and CARTER models.

The results of this study indicate that there are ten factors that are considered very important by Muslim BPJS participants for hospitalization service, with the dominant variables of each factor being sincerity/sincerity of employees in serving BPJS participants, the amount of drugs cost borne by BPJS participants, cleanliness in the hospital building, tabligh attitude in serving BPJS participants (wise and right on target), reputation of BPJS doctors in the hospitals, affordability of the hospital location, compliance and accuracy of payment claim/treatment for BPJS patients, BPJS compliance with Islamic principles, the ability of BPJS to reliably deliver promised services and availability of mosque at BPJS referral hospital.

The new factors that have emerged are location access, information and availability of praying facilities. The sincerity and formality factors are considered very important by the Muslim community when using BPJS Health card for hospitalization service.

The purpose of this paper is to investigate the factors affecting anti-consumption behavior of the consumers toward organic food purchase: in particular, how do individual beliefs about trustworthiness of organic foods, normative structure of social pressure and self-efficacy affect individual intentions to make organic food purchases and actual purchasing behavior? To answer this question, a theoretical framework of the theory of planned behavior (TPB) as its foundation has been established. Using measurement scales in order to measure different aspects of trustworthiness, normative structure, self-efficacy, attitude, perceived behavioral control (PBC) and subjective norms, a survey instrument has been developed to examine the several associations implied by the model of TPB.

In doing so, data on a structured questionnaire were collected from various parts of a city based on convenience random sampling procedure. The respondents were interviewed face-to-face to collect information on a structured questionnaire. Data (n=337) were analyzed using a research framework formulated based on the TPB through the structural equation modeling procedure.

The findings of the study indicate that among the seven independent variables of trustworthiness, normative structure, self-efficacy, attitude, subjective norm and PBC, only subjective norm has not been statistically significant to influence organic food purchase behavior.

The result implies that various sociopolitical forces and skewed monthly incomes are inhibiting the consumers (anti-consumption) to increasingly buy the organic food products.

In this regard, government, policy planners, academia as well as media have profound roles to play to encourage people to buy more organic food for their health safety and overall consumer well-being.

This research is based on primary data collected from the respondents of a sub-urban areas of a metropolitan city. The findings will help formulate a sound food policy for ensuring social well-being of the consumers.

The purpose of this paper is to investigate the factors that influence the intention to choose family takaful in Pakistan through using theory of reasoned action (TRA) model. While family takaful is not a new financial solution in the market, the main factors that motivate customers to purchase family takaful remain unexplored. To fill this gap, this paper investigated the impact of attitude (ATT), subjective norm (SBN) with the addition of Halal certification (HCT) to predict the behavioral intention of customers in Pakistan.

The sample data of 250 respondents was drawn for this paper. The respondents were the regular visitors to the Islamic banks in Pakistan and were selected through judgmental sampling. Of 250, total 237 responses were included in the final study, after excluding the inappropriate and missing responses. For the final data, EFA, CFA and SEM were used to test the significance of relationships between the IVs (ATT, SBN and HCT) and DV (BI).

Findings from the SEM analysis suggest that ATT, SBN and HCT have positive significant relationships with BI. SBN appeared to be the most influencing factor that influences the behavioral intention to purchase family takaful.

The paper has practical implications for takaful managers and academics. Bank managers can draw marketing communication policy based on the findings of this paper. While for academics, this paper laid a foundation for future studies by integrating Halal certification in TRA as a predictor to the behavioral intention towards selecting family takaful. The empirical nature of this paper will enhance understanding of the Islamic financial market and its customers specifically.

The findings of the paper also hold significance for managers and policy-makers of Islamic financial institutes. It guides to design the marketing strategies to develop the right attitude of customers, emphasize subjective norms and Halal certification when communicating the family takaful products to customers. As such, brand managers of family takaful may leverage the role of belief in developing the right attitude and then linking it to the family takaful brand. The attitude is rooted in the belief, and for family takaful brands, it potentially be useful to allow it a broader space in the brand strategies. Likewise, subjective norms in terms of choosing family takaful comprises the perceived social pressure of customers feel towards purchasing takaful for families. It highlights the role of social contacts and effect of their behavior and choices over customers. The recommendations and positive feedback customers receive from their social contacts can be instrumental in instilling the sale of family takaful. In the context of Halal certification, the findings of this paper call takaful brand managers’ attention to the significant role Shariah compliance plays for potential customers of family takaful.

The findings of the paper also have significance for managers and policy-makers of Islamic financial institutes. The findings of this paper guide them to develop marketing strategies, develop the right attitude of customers, emphasize subjective norms and Halal certification when communicating the family Takaful products to customers.

Family takaful is relatively a new phenomenon that demands empirical evidence for academics and managers. This is one of the early studies that investigates the determinants of purchase of family takaful through extended TRA model. Therefore, this investigation will serve as a cornerstone to the scant knowledge of family takaful in Pakistan and around the globe.

The purpose of this study is to investigate the impact factors towards the use of mobile banking among the asnaf for efficient zakat payments by using the unified theory of acceptance and use of technology (UTAUT2) model with additional constructs such as religiosity, attitude and trust (initial trust model) in the Malaysian context.

The structural equation modelling is used to analyse the data collected from 470 asnaf in Selangor, Malaysia, using the survey methodology.

This study highlights factors that could influence the asnaf to adopt financial technology (fintech) in order for them to enjoy the benefit of efficient zakat distribution by the zakat institutions.

This study only investigates and contributes added value from the Malaysian context. While it may be similar to other countries that share similar demographic profiles, it might differ for countries that do not have any demographic similarities with Malaysia.

The result of this study highlights the significant factor that practitioners (zakat institutions) in Malaysia could improve fintech adoption and at the same time enhance the efficiency of zakat distribution for the asnaf.

This research is basically addressing Islamic social financing. Thus, this study has social implications to address the society's poverty eradication scheme pertaining to the efficiency of zakat institutions in Malaysia for the speedier zakat payments to the asnaf. However, other emerging issues also arise particularly in using the zakat funds by the zakat institutions. By right whatever expenditure that the institutions use from the zakat funds need to have the consent from the asnaf because of their religious and legal rights. Hence, this new gap found from the findings of this study could be further explored by other researchers in future studies especially focusing on the drive towards more efficient administration by the zakat institutions of Malaysia in particular and other zakat institutions spread over Muslim countries elsewhere.

This study found that the UTAUT2 model is rarely used and adopted in investigating technology acceptance and adoption especially when it is related to religious matters such as zakat. Indeed, the findings of this study could be acknowledged as something of original value and significance, therefore contributes to the body of knowledge in this field.
