There is a strong prerequisite for organizations to analyze customer review behavior to evaluate the competitive business environment. The purpose of this study is to analyze and predict customer reviews of halal restaurants using machine learning (ML) approaches.

The authors collected customer review data from the Yelp website. The authors filtered the reviews of only halal restaurants from the original data set. Following cleaning, the filtered review texts were classified as positive, neutral or negative sentiments, and those sentiments were scored using the AFINN and VADER sentiment algorithms. Also, the current study applies four machine learning methods to classify each review toward halal restaurants into its sentiment class.

The experiment showed that most of the customer reviews toward halal restaurants were positive. The authors also discovered that all of the methods (decision tree, linear support vector machine, logistic regression and random forest classifier) can correctly classify the review text into sentiment class, but logistic regression outperforms the others in terms of accuracy.

The results facilitate halal restaurateurs in identifying customer review behavior.

Sentiment and emotions, according to appraisal theory, form the basis for all interactions, facilitating cognitive functions and supporting prospective customers in making sense of experiences. Emotion theory also describes human affective states that determine motives and actions. The study looks at how potential customers might react to a halal restaurant’s consensus on social media based on reviewers’ opinions of halal restaurants because emotions can be conveyed through reviews.

This study applies machine learning approaches to analyze and predict customer sentiment based on the review texts toward halal restaurants.

The purpose of this paper is to investigate the factors that enable total quality management (TQM) implementation in the readymade garment (RMG) sector of Bangladesh. More specifically, the present study is a supplement of the previous call from research to investigate the TQM-enabling factors from a broader aspect of organizational change.

This study was conducted through an online survey, followed by phone calls. Data were collected using a questionnaire survey with 256 respondents of the Bangladeshi RMG sector. The TQM-enabling factors were divided into five distinct groups, based on strategic or overall changes required within an organization for TQM implementation. A theoretical research model was created to investigate the contingency of various TQM-enabling factors. Structural equation modeling (SEM) was applied to confirm the factor that enabled TQM implementation in the RMG sector of Bangladesh.

The main finding of this study shows that structural, strategic, contextual and human resource-enabling factors are significant to TQM implementation in the Bangladeshi RMG sector.

This study has been completed in single time frame. Therefore, consideration of the time factor is completely ignored in this research. Furthermore, understanding of TQM-enabling factors in this research relied on quantitative findings only. Also, this study was limited to one industry and one geographic region. However, this study could determine whether data triangulation will provide a good perception on enabling factors and the methodology can be extended to other industries and regions.

This study provides a research methodology for other manufacturing industries that are planning to implement TQM in their organization. This research will contribute to the existing literature by examining the contingency of various TQM-enabling factors in the context of the Bangladeshi RMG sector, and it, therefore, provides direction to increase the success rate of TQM implementation. Furthermore, the research methodology can be used in other studies for variation of contextual variables such as size of the industry, developed or underdeveloped country and manufacturing or service industry.

The methodology used in this study can lead the way for other industries in the RMG sector that implements TQM in their organization. Also, this research further contributes to the existing literature by investigating the contingency of various TQM enabling factors in the context of the Bangladeshi RMG sector and developing associated strategies to raise success rate of TQM implementation.

The purpose of this paper is to investigate the relative importance of different total quality management (TQM) implementation barriers in the context of Readymade Garment (RMG) industries in Bangladesh. Present study has developed a hierarchical framework of several TQM barriers to assess their importance. Expert opinions from RMG industries have been taken to evaluate the importance of one barrier over another.

Methodology adopted in this study to find out the rank of different TQM barriers is fuzzy analytic hierarchy process.

The study shows that, according to order, inappropriate planning of TQM implementation program, lack of financial support, lack of employee training, lack of empowerment of employees, lack of sufficient physical resources, etc. are critical barriers and hampering the successful implementation of TQM program in this sector.

This study has both theoretical and practical implications. It has found out strong and weak contribution of different barriers during TQM implementation. Therefore, this finding will strengthen the knowledge of successful implementation of TQM and will further enrich the existing literature in the context of manufacturing industries in developing countries. Moreover, this finding will also help the decision makers in preparing an effective plan for successful implementation of TQM by utilizing limited resources.

Moreover, our results will aid the managers of RMG sector to find the weight of importance of different barriers. Accordingly, they will make a plan to overcome the major TQM barriers which will increase the success rate of TQM implementation. Every Successful program will bring business excellence. These findings could be a guideline for TQM implementation program in developing countries.

Present study possesses some significant values. First, so far our knowledge go, no other study has developed a hierarchical structure of TQM barrier on the basis of overall change needed within the organization for TQM implementation. Second, this study could be a good guideline for TQM implementation program in RMG sector in developing countries.

This article aims to present a methodology applied to the transition between the “as-is” and “to-be” stages of the Business Process Management (BPM) life cycle, supporting its implementation and maintenance for the organizational stability, using techniques from Operations Research and Information and Decision Theories, applied by a gamified system.

The study used Design Science Research, considering the following methodological elements: (1) artifact model, after initial analysis of the organization; (2) problem relevance, incorporating components to the Markov transition matrix and the integer programming model for resource optimization; (3) model evaluation, establishing mechanisms to validate the methodology created; (4) research contributions, showing benefits found; (5) systematic approach, detailing methods used; (6) model's research process, revealing the means for execution; and (7) final presentation of results.

After planning three scenarios for the company, containing zero, one or two implemented processes, the matrix of states in the Markov chain effectively identified the states of greater and lesser transition uncertainty. At the same time, the optimization model guided the organization toward a stable change in its operational and financial areas.

The company's planning capacity has increased, as its managers now have a methodology to promote rational decisions about the development of plans. Before, managers believed that the methodology used was only for large companies. However, this view changed with the results, showing a structured view of the ability to absorb new customers, relocate established ones, increase the comfort level for employees and increase profitability for the company's business.

The study showed that the combination of techniques opens a new perspective to the incorporation of BPM in organizations, allows a smooth change between the current and future state, making it possible to predict the evolution of transition scenarios.

The shipbreaking sector in Bangladesh has spurred extensive academic and policy debates on relations between shipbreaking industries, environmental degradation and the health security of their workers. As shipbreaking is an economically significant industry in Bangladesh, it needs to implement both domestic and global mechanisms for environmental conservation and the protection of the labourers’ health from environmental risks. The purpose of this paper is to primarily explore the environmental and health security issues in shipbreaking activities in Bangladesh. It also identifies the challenges in implementing the rules and regulations for protecting the health of the workers at shipbreaking yards in Bangladesh and preserving the marine environment.

This is a qualitative paper based on secondary materials, including journal articles, books and national and international reports. It critically reviews the existing literature, rules, regulations and policing on shipbreaking with a particular focus on the environment and health security of the workers.

This paper finds that the implementation of the rules and regulations in shipbreaking in Bangladesh is complicated because of weak implementation mechanisms, political and economic interests of the yard owners, lack of coordination among different agencies, lack of adequate training and awareness among the workers and workers’ poor economic condition, which contribute to the degradation of marine and local environments and trigger health hazards among the workers. Therefore, degrading the environment and undermining occupational health and safety regulations have become regular; thus, accidental death and injury to the workers are common in this sector.

This paper is an important study on the issues of workers' health and safety and environmental hazards in the shipyard. It reports how the health security of the workers in shipbreaking yards in Bangladesh is vulnerable, and environmental rules are challenged. Finally, this paper frames some policy implications to safeguard the workers’ health rights and the marine environment.

The aim of this study is to investigate the perceived benefits offered by integrated management system (IMS) in the readymade garments (RMG) sector in Bangladesh and the respective linkage with corporate social responsibility (CSR) to promote sustainable development. This study presents a list of IMS benefits composed of different international management standards according to ISO 9001:2015, ISO 14001:2015, OSHAS 18001: 2007 and SA 8000:2014.

To identify the possible benefits of IMS, a systematic literature review was conducted from 2009 to 2019, namely, in the database of Elsevier, Emerald and John Wiley. A questionnaire survey was developed with the purpose of examining the perceived main benefits of IMS. The questionnaire was e-mailed to 355 representatives of 15 RMG sectors in Bangladesh. A total of 256 complete and useable responses were received, constituting the base of this work. Subsequently, statistical analysis was conducted using SPSS 20 software.

The main findings of the present study show that the most important five benefits of IMS in RMG sector in Bangladesh are better capacity to achieve organization’s objectives, optimum use of various resources, business sustainability, synergies of different management policies and reduction of duplication efforts.

Two major limitations of the study are as follows: first, it is not a longitudinal study; second, IMS benefits were examined in the national sector context. The present study has both theoretical and practical implications. The study presents a comprehensive list of IMS benefits that contribute to the existing literature from a theoretical point of view. On the other hand and from a practical point of view, this study encourages managers to implement IMS in their organizations.

This study helps in understanding the contribution of IMS benefits to cleaner production and CSR in Bangladesh. The focus on the benefits of IMS in the RMG sector in Bangladesh is another significant aspect of this study because it promotes the development of environmental policies linked to CSR with stakeholder engagement, as a driver to sustainable development.

This paper aims to compare and contrast the concept of conventional futures contract from the Islamic law of contract perspectives. The underlying theory and practice of Islamic finance is based on the principles of Islamic law of contract. Although the necessity of derivative instruments such as the case with futures contract is essential for developments in Islamic finance, the permissibility of using these instruments still remains a debatable issue.

The paper discusses arguments for and against using derivative instruments as in futures, for example, in light with the Qur’an and Sunnah (the Prophet’s traditions), as well as the views of classical scholars, jurists and contemporary researchers. Arguments for and against are analysed systematically to derive a logical conclusion.

The study finds that majority scholars consider futures contracts as non-compliant with the Islamic law due to the fact that selling something that does not exist, deferment in the both counter values, gharar or ambiguity and excessive risk taking, pure speculation and sale of one debt for another.

The study focuses narrowly on conventional futures contract. Analysing other financial derivative contracts could be a future research endeavour.

The study has so far found the verdict of impermissibility of conventional futures contract in its current form as has been argued by majority scholars in the premise that they do not comply with the Islamic law. Policymakers and industry practitioners need to take this opinion of majority scholars while developing new Islamic financial derivatives.

To the best of the author's knowledge, the present research is the first attempt so far that explained the validity of conventional futures by analysing arguments of classical and contemporary jurists, scholars and researchers.
