Abstract

Purpose

This study aims to evaluate the amount of entropy generation around the NACA 0012 airfoil. This study takes place in four angles of attack of 0°, 5°, 10° and 16° and turbulent regime. Also, the variation in the amount of generated entropy by the changes in temperature and Mach number is investigated.

Design/methodology/approach

The governing equations are solved using computational fluid dynamics techniques. The continuity, momentum and energy equations and the equations of the SST k-ω turbulence model are solved. The entropy generation at different angles of attack is calculated and compared. The effect of various parameters in the generation of entropy is presented.

Findings

Results show that the major part of the entropy generation is at the tip of the airfoil. Also, increasing the angle of attack will increase the entropy generation. Also, results show that with increasing the temperature of air colliding with the airfoil, the production of entropy decreases.

Originality/value

Entropy generation is investigated in the NACA 0012 airfoil at various angles of attack and turbulent flow using the SST turbulence model. Also, the effects of temperature and Mach number on the entropy generation are investigated.

Abstract

Purpose

The main objective of this study is to consider how to benefit efficiently from the significant potential of humanitarian operations by individuals. For this purpose, this study aims to assess failure factors in humanitarian supply chain operations after the Kermanshah earthquake considering the role of all parties, focusing on individuals who did not wish to work with formal organisations on the whole. In the aftermath of the Kermanshah earthquake, which occurred on 12 November 2017, improvised groups of Iranian civilians from all over the country played an important role in humanitarian supply chain operations as individuals. Although most of these groups sincerely intended to help the affected society, victims could not benefit properly from these significant potential humanitarian actions. On the contrary, these potential actions caused some issues during humanitarian operations, such as blocking roads, inappropriate last-mile distribution, wasting resources and so on.

Design/methodology/approach

This research study considers mixed methods, including an on-site survey, semi-structured interviewing and a questionnaire designed for statistical analyses. The analysis included 140 responses to the questionnaire, semi-structured interviews with 32 affected families, interviews with 5 emergency managers from the Housing Foundation of the Islamic Republic of Iran and on-site survey reports.

Findings

This study presents a framework for humanitarian supply chain management to deal with future disasters in the same area or areas with similar characteristics to the case study. In general, the results of this study demonstrate that the nature of humanitarian supply chain operations makes it impossible to consider that these operations are free of challenges. However, several influential factors, such as training humanitarian actors and integrated management, might considerably increase the efficiency of humanitarian operations by individuals.

Originality/value

This study highlights the influential factors of inappropriate humanitarian operations by individuals, derived from an analysis of the Kermanshah case and literature review. The authors suggest a framework to benefit from the significant potential of individuals with wide-ranging experiences and proficiency, for future cases similar to the case study.

Abstract

Purpose

One of the main challenge when launching new banking services is to overcome resistance to change so as to accelerate market acceptance. This is the case of an Islamic credit card (ICC). Grounded in innovation diffusion theory (IDT) and theory of reasoned action (TRA), this paper aims to study the purposes and empirically tests an integrated model to explore, which factors influence of ICC.

Design/methodology/approach

Partial least squares and structural equation modeling was used to assess the hypotheses. Accordingly, the empirical results, obtained in a sample of 762 bank customers.

Findings

Intentions to use of ICC are mostly determined by relative advantage, compatibility, customer awareness, satisfaction and attitude. The combination of IDT and TRA significantly explain the ICC adoption.

Originality/value

This research has provided a theoretical understanding of the ICC adoption determinants with the intent of promoting a more in-depth understanding of various elements influencing acceptance and usage of this Islamic banking service.

Abstract

Purpose

Mobile banking or m-banking enables consumers to carry out their banking affairs with the help of mobile devices. Mobile-user banking interactions in the context of technology services create opportunities for positive experiences that can nurture trust, foster brand equity and eventually lead to long-term relationship building. The purpose of this paper is to examine the concepts of m-banking customer flow experiences and their role in affecting customer intention in the continued use of m-banking.

Design/methodology/approach

To achieve this main objective, a research model was developed by taking theoretical backgrounds and specific characteristics of m-banking into consideration for testing. The study to test this model was carried out in Iran, a developing country in the Middle East.

Findings

Results of the PLS-SEM analysis of 927 bank customers showed that the flow experience is positively influenced by both hedonic and utilitarian features. While, flow experiences influence trust and brand equity, individual mobility has a stronger effect on the intention to continue the use of m-banking compared with trust, flow experience and brand equity.

Originality/value

The current research provides various useful insights into customer engagement for conducting banking tasks via mobile technologies. Managers and decision makers can take into account the following insights to enhance positive flow experiences and loyalty intention of customers toward m-banking.

Abstract

Purpose

The purpose of this paper was to examine the intention to adopt mobile banking services among Generation Y consumers using the unified theory of acceptance and use of technology Unified Theory of Acceptance and Use of Technology (UTAUT) model.

Design/methodology/approach

The paper investigated responses from a particular sub-group of Generation Y consumers that is college or university students. The final sample collected was 347 cases, representing a response rate of 90.4 per cent. Two sets of analyses were performed: multiple regression analyses testing the extended UTAUT model and a mediated regression analysis testing the intervening effect of performance expectancy (PE) on the relationship between effort expectancy (EE) and behavioural intention.

Findings

Multiple regression analysis revealed PE as the strongest predictor, followed by EE, perceived risk and social influence. The prediction model explained 68.3 per cent of the variance in intention to adopt mobile banking. Mediation analysis supported a partial mediation effect of PE on the relationship between EE and intention to adopt mobile banking.

Research limitations/implications

This study examined respondents’ intention to adopt mobile banking instead of their actual behaviour. Understanding behavioural intention is essential, but it may not accurately represent actual behaviour. In addition, results from this study may not be generalisable to the whole population of Generation Y college or university students due to selection bias and a lack of information concerning the sampling frame.

Practical implications

This research identifies the factors that affect the intention to adopt mobile banking among the Generation Y college or university students. Bank operators can use the findings to improve their marketing strategies and services offered to make them more attractive and competitive to students to speed up the mobile banking adoption rate.

Originality/value

This study is one of the few local studies that introduce a practical model of extended UTAUT by including perceived risk to understand the mobile banking adoption intention among millennial generation.

Abstract

Purpose

In the past three decades, the expansion of Islamic banking has been recognized as one of the most significant financial developments across the world, and to enhance their market share in the highly competitive global banking market, these Islamic banking institutions must continue to be innovative. Credit cards are popularized worldwide; developing countries are also intrinsically motivated to adopt this product for performing financial transactions; however, understanding the factors influencing Islamic credit card (ICC) adoption remains limited, and the ICC still needs to attain adequate market share in the banking sector. Therefore, this study aims to investigate the determinants of ICC in Pakistan.

Design/methodology/approach

For empirical estimation, sample data from 499 respondents, including ICC users and individuals willing to use ICC, is utilized through partial least square structural equation modeling.

Findings

The results show that attitude, compatibility, perceived behavioral control and religiosity are positive, while complexity negatively affects ICC adoption. In contrast, social influence, trust and satisfaction are insignificant determinants of ICC’s intention to use in Pakistan.

Originality/value

As a banking service, ICCs are viewed as a new banking product in Pakistan and have limited scope in the literature. Therefore, this study contributes to the existing literature by providing more integrating policy insights to academians and banking managers on ICC service in Pakistan.

The purpose of this study is to undertake a systematic literature review (SLR) on intellectual capital disclosure (ICD), focusing on its role in fostering competitive advantage.

Abstract

Purpose

The purpose of this study is to undertake a systematic literature review (SLR) on intellectual capital disclosure (ICD), focusing on its role in fostering competitive advantage.

Design/methodology/approach

Following the SLR process, the study identified 84 papers published in high-ranking journals over a 19-year span, providing insights into descriptive outcomes, research limitations and future research directions.

Findings

The results show that ICD research peaked in 2022, with the Journal of Intellectual Capital leading with the highest number of ICD publications. Resource-based theory was found to be the most applied theoretical framework, with developed country-specific research receiving the most attention. The use of small sample size, a lack of longitudinal studies, reliance on a single source of data, unsuitability of control variables and a lack of comparative studies with firms operating in developing countries are the main limitations that have been noted.

Research limitations/implications

This study faces constraints, primarily stemming from the selective keyword utilization and exclusive Scopus database reliance. It omits non-English papers, conference proceedings and books, potentially overlooking relevant insights.

Practical implications

The findings offer valuable insight for researchers, emphasizing the need for research on intellectual capital (IC) across diverse industries. Furthermore, our findings urge regulators to mandate global IC reporting to mitigate information asymmetry, while also prompting managers to enhance IC-related practices and reporting for more stakeholders’ trust.

Originality/value

This study provides a comprehensive overview of over two decades of ICD literature, synthesizing previous studies, identifying gaps and outlining potential directions for scholars and industry professionals in the context of competitiveness.

Abstract

Considering sustainability and resilience together is crucial in food supply chain (FSC) management, as it ensures a balanced approach that meets environmental, economic and social needs while maintaining the system's capacity to withstand disruptions. Towards this, a multi-objective optimisation model is proposed in this study to create an integrated sustainable and resilient FSC. The proposed model employs four objective functions – each representing a dimension of sustainability and one for resilience and utilises an augmented ϵ-constraint method for solving. The findings highlight the interplay between sustainability aspects and resilience, illustrating that overemphasis on any single dimension can adversely affect others. Further, the proposed model is applied to the case of Indian mango pulp supply chain and several inferences are derived. The proposed model would assist decision-makers in making a well-balanced choice based on sustainability and resilience considerations.

Abstract

Purpose

The purpose of this paper is to empirically examine the factors that influence a consumer’s attitude and intention to use mobile wallets using a sample representative of Indian users.

Design/methodology/approach

A multidisciplinary model is proposed, building on the technology acceptance model (TAM) and unified theory of acceptance and use of technology (UTAUT) and other relevant research on factors, which influence technology adoption. A synthesis of review of literature on factors influencing technology adoption besides two focus group discussions (FGD) was used as a design a pilot instrument. A nationwide primary survey was conducted using the questionnaire. Convenience sampling was used to select the respondents. In total, 744 respondents participated in the survey, and 17 hypotheses were formulated and PLS-SEM was used to estimate and test the hypothesized model.

Findings

The results show that factors like perceived ease of use (PEOU), perceived usefulness (PU), trust, security, facilitating conditions and lifestyle compatibility have a significant impact on the consumer attitude and intention to use mobile wallets. Of the proposed 17 hypotheses, 15 were accepted. Ease of use significantly influenced usefulness and trust, whereas PU significantly influenced trust, attitude and intention. Security and trust were found to be play an important role in determining trust.

Research limitations/implications

This study examines the perception of students and working professional from large Indian cities. A larger representative sample encompassing balanced representation from urban and rural India could enhance the scope and widen the application of the results across larger target groups. This study analyzes data at a specific point in time. Considering the rapidly changing rate of adoption of mobile wallets, a longitudinal study could, therefore, be conducted. Furthermore, the possibility of including other antecedents like relative advantage, perceived benefits, personal innovativeness among other factors, which have not been addressed here can be explored. Also, additional research can help examine the role of demographics in adoption of mobile wallets including its moderating effect.

Practical implications

As security and trust emerged as important constructs for acceptance of mobile wallets, there is a need for developing an integrated robust, reliable and secure infrastructure. A joint think tank involving key stakeholders (financial institutions, mobile wallet providers, government, security experts, etc.) should propose guidelines to ensure safe and secure transactions. The findings have managerial implications, which can guide companies offering mobile wallets to enhance usage and adoption of such services.

Originality/value

Mobile wallets have provided newer digital payment avenues to consumers while offering companies and marketers greater opportunities to market their products and services, online. However, not much is reported about the adoption of mobile wallets in India. The study is perhaps the first in India to examine the adoption of mobile wallets using a larger sample in comparison to earlier studies. The study proposes and validates additional constructs, which were not present in the original model.

Abstract

Purpose

Domestic refrigerators could be considered as one of the major potential sources of food-borne diseases, in addition limited data are available regarding the level of contamination of domestic refrigerators in Iran. The purpose of this paper is to detect some of bacterial contamination in domestic refrigerators.

Design/methodology/approach

In total, 104 households were randomly selected from ten health centers in five areas of Tehran, Iran. Visual inspection and temperature evaluation of the households’ refrigerators were done. In addition, the refrigerators were swabbed and analyzed for contaminants using polymerase chain reaction (PCR) method. DNA was isolated and purified by the proposed standard protocol.

Findings

Screening of the domestic refrigerators by PCR method showed that 51.7 percent of the samples were positive for pathogens as follows: L. monocytogenes 41.6 percent, S. aureus 5.5 percent, Salmonella spp 4.6 percent, and E. coli O157:H7 0 percent; consequently, none of mentioned pathogens were detected in 48.3 percent of the refrigerators. Results of the visual inspection indicated that 57 percent of the refrigerators were on desirable, 36.5 percent were acceptable, and 7 percent were weak conditions. Most of the refrigerators about 44 percent had desirable temperatures. There were no significant correlations between the visual inspection scores, temperature and frequency of isolation of specific pathogens in the domestic refrigerators. A significant correlation was observed between contamination and education of parents (p < 0.05).

Originality/value

Determination of the bacterial contamination and evaluating the temperature of domestic refrigerators in Iran can be considered as a novel approach of current study. These findings could be employed in designing and implementing appropriate educational interventions to promote food safety and diminish the risk of food-borne illnesses. Also, obtained results might be applied as introduction for further investigations.
