Winglets play a major role in saving fuel costs because they reduce the lift-induced drag formed at the wingtips. The purpose of this paper is to obtain the best orientation of the winglet for the Office National d’Etudes et de Recherches Aérospatiales (ONERA) M6 wing at Mach number 0.84 in terms of lift to drag ratio.

A computational fluid dynamics analysis of the wing-winglet configuration based on the ONERA M6 airfoil on drag reduction for different attack angles at Mach 0.84 was performed using analysis of systems Fluent. First, the best values of cant and sweep angles in terms of aerodynamic performance were selected by performing simulations. The analysis included cant angle values of 30°, 40°, 45°, 55°, 60°, 70° and 75°, while for the sweep angles 35°, 45°, 55°, 65° and 75° angles were used. The aerodynamic performance was measured in terms of the obtained lift to drag ratios.

The results showed that slight alternations in the winglet configuration can improve aerodynamic performance for various attack angles. The best lift to drag ratio for the winglet was achieved at a cant angle of 30° and a sweep angle of 65°, which caused a 5.33% increase in the lift to drag ratio. The toe-out angle winglets as compared to the toe-in angles caused the lift to drag ratio to increase because of more attached flow at its surface. The maximum value of the lift to drag ratio was obtained with a toe-out angle (−5°) at an angle of attack 3° which was 2.53% greater than the zero-toed angle winglet.

This work is relatively unique because the cant, sweep and toe angles were analyzed altogether and led to a significant reduction in drag as compared to wing without winglet. The wing model was compared with the results provided by National Aeronautics and Space Administration so this validated the simulation for different wing-winglet configurations.

The importance of innovation has attracted growing attention due to the complex and rapidly changing business environment. This study aimed, first, to examine the joint effect of servant and authentic leadership (AUL) styles on employee creativity (EC), second, to examine the direct and mediated effect of servant leadership (SL) on employees' innovative work behaviour (IWB), third, to examine the effect of EC on IWB and finally, to investigate the moderating effect of creative self-efficacy (CSE) on the relationship between AUL and EC.

A quantitative approach was used, and the data were collected from 446 employees in the Qatari public sector. The data were then analysed by employing partial least squares structural equation modelling (PLS-SEM) using SmartPLS software to validate the measures before testing the proposed model.

The results of this study emphasized the strong hypothesized link between EC and IWB. It also endorsed the mediating role of EC between SL and IWB and the moderating role of CSE in the AUL-EC relationship.

The originality of this study comes from various aspects. First, it is unique in separately examining EC and innovation and the link between them. Second, it investigates the joint impact of servant and AUL styles on EC. Third, it explores the mediating role of EC between SL and IWB. Fourth, the moderating effect of CSE on the AUL-EC link also was examined to gain a full understanding of the relation effect. Finally, the value of the current study also comes from the integration of the triangular theory of creativity, SL and AUL theories and self-efficacy theory to explain the proposed model of the study. Moreover, this study serves as a guideline for decision-makers on how to enhance IWB among employees by focusing on leadership programmes and the creative and innovative culture.

This study examines learner readiness and satisfaction with blended learning systems in India’s post-vaccine classrooms, focusing on the relationship between face-to-face (F2F), online learning (OL), and blended learning (BL) indicators and identifying which predictors within these systems most significantly affect learners’ satisfaction (LS).

An online survey was conducted with 451 students from both public and private universities in India. The data were analyzed using factor analysis and confirmatory factor analysis, followed by multiple regression to test the hypotheses.

The findings reveal a significant positive correlation between learners’ satisfaction and online learning and blended learning, with β values of 28.3 and 27.2, bearing a p-value of 0.000. In contrast, face-to-face (F2F) learning was insignificant, with a β value of 0.070 and a p-value of 0.119. These insights underscore the effectiveness of online and blended learning formats in enhancing learner satisfaction in higher education while also suggesting a re-evaluation of the role of traditional F2F learning methods. The research supports the integration of online learning in higher education due to its balanced mix of teacher-led and student-centered instruction, alongside the practical benefits of reduced travel costs and access to independent study resources.

This study provides insights into student perceptions and attitudes towards blended learning in India’s post-vaccine classrooms. It highlights the importance of tailoring blended learning strategies to meet colleges’ and universities’ diverse learning needs and goals in this evolving context. The findings serve as a valuable resource for educators and administrators, aiding in designing effective blended learning frameworks suited explicitly for higher education in India.

While there is extensive literature on F2F, OL, and BL, limited research compares these learning approaches and their impact on learner satisfaction within the Indian higher education context. This study fills this gap by providing valuable insights for shaping educational strategies in India’s post-vaccine classrooms.

Cultural sensitivity is a vital issue in heritage site management, encompassing a profound respect for cultural variety, traditions and values. This delves into the significance of cultural sensitivity in heritage site management, emphasising its function in maintaining cultural authenticity while ensuring a high-quality traveller revel in. Heritage site management necessitates a cautious and respectful method to the maintenance of cultural authenticity. Cultural sensitivity entails recognising the cultural significance of heritage sites, the groups that defend them and the sacred rituals that imbue these sites with ancient and cultural value. Cultural sensitivity is important for heritage site management. It shows how respecting these locations and their communities' cultural legacy is essential to cultural authenticity. By creating a harmonious balance between conservation and a meaningful vacation experience, cultural sensitivity ensures that background sites have a good time and shield their cultural authenticity. This also explores diverse techniques for promoting cultural sensitivity in heritage site management, consisting of network involvement, regulatory frameworks, collaborative partnerships and addressing cultural insensitivity. It emphasises the significance of instructing traffic, setting respectful behaviour codes and engaging with neighbourhood groups to ensure the maintenance of cultural and heritage. Cultural sensitivity serves as a cornerstone in heritage site management, guiding the sensitive dance among retaining cultural authenticity and offering a memorable experience for site visitors. It is a fundamental principle that guarantees heritage sites are reputable, celebrated and preserved in a way that aligns with their cultural importance while fostering a respectful and tasty tourist experience.

This study examines the effect of open-mindedness (OM) and humble behavior on innovation through the mediator role of learning.

A quantitative design was adopted to collect data through a questionnaire-based survey distributed to 400 employees at international oil companies operating in Iraq.

The results indicate a direct positive of learning on innovation. Hence, there is a natural and partial indirect effect of humble behavior on innovation and a full indirect impact of OM on innovation through learning.

The theoretical and practical implication of this study indicates that individual learning on innovation is vital when the workplace environment has a diversity of cultural backgrounds. Moreover, the implications of this study may contribute to determining the weakness of invention in such industries because of the effect of personal characteristics (i.e. OM and humble) on readiness to learn.

In a culturally diverse work environment, the behavior of humble and OM will have a significant impact on the intensity of individual learning, which would increase innovation in the context of the oil industry. Therefore, the essence of originality in this study is to lead the managers to pay attention to the psychological aspects of the workplace environment that require learning and innovation.

This paper aims to investigate the influence of the determinants (pricing, type of structure, Shariah auditing, Shariah risk and Shariah documentation) and the sukuk legitimacy among Islamic financial institutions using a qualitative approach. The paper further explained the significance of the determinants on legitimacy, evaluated the relationship between sukuk characteristics and sukuk legitimacy and examined the moderating effect of Shariah Supervisory Board (SSB) on the relationship.

The study used a purposive sampling technique to select the target respondents required for the survey (semi-structured interview). This technique is applied by selecting members of SSBs among Islamic financial institutions. A total number of ten members are selected as the sample size for the study based on their experience and basic knowledge of Fiqh Al-Mua’malat and its application in Islamic financial institutions.

The findings revealed that the determinants have a significant impact on the sukuk legitimacy, meaning that there is a positive and significant relationship between the determinants and the sukuk legitimacy. In addition, this study indicates the empirical evidence of the moderating effect of SSB on the relationship between the determinants and the sukuk legitimacy.

This study has added to the literature by examining the determinants of sukuk legitimacy while evaluating the moderating effect of SSB on the relationship. Besides, this might add benefits to the numerous Islamic financial institutions relating to the amendment of its regulatory frameworks with the view to pushing the sukuk market investors to move toward asset-backed structure. In addition, the SSB in central banks must also focus its attention regarding the sukuk legitimacy and its application among the various Islamic financial institutions.

This study has added a new discussion to the body of knowledge, i.e. examining the sukuk legitimacy and its relationship with sukuk determinants; hence, an approach that is not widely discussed in the previous studies. Furthermore, conducting such research in the field of Islamic finance provides novelty in the literature among both emerging and developed economies including Malaysia. This is because to the best knowledge of the researchers, there was no empirical study (within the literature) that combined these variables and evaluated their empirical significance. Accordingly, this would enlighten the Islamic Ummah and propel the society’s intensity toward contributing to knowledge and might further provide clarification on the determinants and the sukuk legitimacy to prospective scholars, precisely on the moderating effect of SSB on the relationship between determinants and legitimacy of sukuk.

The purpose of this study is to understand the residents’ perception towards environmental, social, cultural and economic impacts of tourism development in Kashmir.

The research instrument containing 27 items pertaining to six variables is adopted from the literature. A mix-method survey approach is used to solicit residents’ perceptions regarding environmental, social, cultural and economic impacts of the current level of tourism development.
