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 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. A total of 326 useful responses were subjected to descriptive statistics, analysis of variance (ANOVA) and post hoc analysis using SPSS (Version 22.0).

In general, the negative and positive impacts of tourism development are well perceived by the residents. The results indicate that the residents display positive perception regarding economic impacts, however, social and environmental impacts are negatively perceived. Furthermore, barring level of education, the study found no significant difference in the residents’ perception towards tourism impacts (environmental, social, cultural, economic, quality of life and cost of living).

The paper identifies perceived impacts and issues of tourism development thereby, proposing possible mitigating measures. Also, the study identifies the need to develop a comprehensive policy framework addressing the issues related to the resident’s negative feelings towards tourism impacts. Further, the study envisages the need for engaging residents in developing a progressive and participatory planning process for future tourism activities in the area.

The study offers critical social implications for city tourism development. It suggests a community-based approach should be adopted to sensitize residents about the positive benefits of tourism.

The study is a novel attempt concerning residents’ residents perceptual differences towards tourism impacts. Furthermore, this study investigated socio-cultural impacts of tourism under two separate categories for better understanding. in doing so, this study provides finer understanding of perception of residents towards tourism impacts in Indian context. The findings of the study will prove critical for different stakeholders in developing future tourism framework and policies in the region.

This paper introduces the concept of manihah and develops a conceptual framework to address Malaysia's abandoned lands and food security issues.

This is a conceptual paper based on insights from the existing literature and secondary data on food security, abandoned lands and manihah. Based on the prevailing gaps, the study proposes a conceptual framework of the Manihah Agricultural Financing Model to address Malaysia's abandoned land and food security issues.

The proposed model can address abandoned lands and food security issues due to the new incorporation of manihah within Malaysia's agricultural and Islamic financial industries' milieu.

This is a conceptual paper mainly intended to spark a discussion on the potentiality of manihah.

The paper contends that Islamic banks have a crucial role in furthering the socio-economic development agenda under the value-based intermediation (VBI). The paper will also be an excellent introduction to Islamic bank practitioners in understanding manihah's relevance to their daily operation.

This paper introduces manihah as the potential solution to food security issues by utilizing abandoned lands.

The study is interested in knowing “the role of the organizational structure as a mediating variable of the relationship between the information technology and organizational communication”.

The study was conducted in several service companies, and the study adopted the questionnaire as a basic tool for the data collection on the practical side, as 267 opinions were surveyed, in addition to conducting personal interviews, and the normal distribution of data was tested, analyzing, describing and diagnosing study variables, testing correlations and determining direct effects.

Findings show that there is no direct and significant statistical impact of information technology on organizational communications. Whereas there was a positive, direct and statistically significant impact of information technology on the organizational structure. There was also a positive, direct and statistically significant effect of the organizational structure on organizational communication.

This paper is restricted to the role of the organizational structure as a mediating variable of the relationship between the influence of information technology on organizational communication.

As part of the practical implication, the paper suggests the need to increase support and attention to the importance of information technology in service organizations in order to increase coordination and organizational communication and achieve a high ability to explore and exploit ideas.

Apart from the fact that several companies were engaged, the organizational structures of these companies were engaged too to examine the impacts of Information technology (ICT) on organizational communication.

This paper aims to improve the understanding of the institutional pressures that shape the intention to adopt waqf accounting and reporting. The study seeks to answer two research questions as follows: what are the challenges in the adoption of waqf accounting and reporting in waqf institutions; and how do institutional pressures influence the adoption of waqf reporting in Malaysia. Drawing on the work of DiMaggio and Powell and Scott of institutional theory, this paper provides empirical evidence of institutional pressures on the adoption of waqf reporting in Malaysia and the challenges faced in adopting waqf accounting and reporting.

This study uses qualitative research method with an explanatory case study approach. Data are collected through semi-structured interviews with the accountants of State Islamic Religious Council and Customs of Terengganu, an informal conversation with the Deputy Director of Accountant Generals Department of Malaysia and document reviews, mainly the Malaysian Accounting Standard Board Research paper.

The findings show that coercive pressure such as government regulation contributes to challenges in the adoption of waqf accounting and reporting. Normative pressures contribute to challenges in formulating standardised waqf accounting and reporting, whereas mimetic pressure contributes to challenges in the comparability of the waqf accounting and reporting among the state Islamic religious councils in Malaysia. In the efforts towards the standardisation of waqf accounting and reporting practice, a similarity of the process of the standard implementation or the institutional isomorphism of the State Islamic Religious Council in Terengganu is strongly influenced from the result of the mandate of its Board members and Fatwa council members (coercive isomorphism and religion logic) and minor influence from the normative isomorphism (the result of the participants’ education and profession) as well as the result of imitating other State of Islamic Religious Councils (SIRCs) because of the ambiguity of the process or certain practice.

The study contributes to the knowledge by extending institutional theory and the possible role of religion logic in Islamic perspective to organisational behaviour and accounting development in SIRCs. This study is limited to the understanding of the challenges in the adoption of waqf accounting and reporting but could also be applicable to the adoption of other accounting standards or regulations.

This paper offers key implications for research, in improving the understanding of contextual factors and decision to adopt waqf accounting and reporting. The standard setter needs to be aware of the influence of contextual factors that shape decision towards standardisation of accounting and reporting for waqf.

The interplay of institutional pressures and implications of religion logic provides an interesting approach to understanding the waqf institutions’ intention to adopt accounting and reporting for waqf.
