The purpose of this study is to extend the extant literature on the relationship between financial risk tolerance (FRT), awareness of Islamic financial principles (AWIF) and positive financial behaviour (FB) on financial satisfaction (FS) of micro, small and medium enterprise (MSME) owners by principally investigating the mediating effect of access to Islamic financing (AIF) on these relationships.

A quantitative survey method of data collection through a self-administered questionnaire. The sample of 384 MSME owners was selected in which 208 questionnaires were retrieved and analysed using the partial least square structural equation modelling (SEM).

The result shows that the relationships between FRT and AIF as well as FB and AIF are not significant. However, the AWIF–AIF relationship was found to be positively significant. Moreover, only the mediating effect of AIF on the AWIF–FS relationship was established.

The result implies that AIF could strongly influence the FS of MSME owners, and the AWIF–FS relationship is better explained with sufficient AIF. However, AIF could not mediate the relationships between FRT–FS and FB–FS. Therefore, policymakers and MSME owners should emphasize on AWIF and AIF to enhance FS.

This study pioneers the examination of the mediating influence of AIF on FRT, AWIF, FB and FS of MSME owners in a single framework. Despite the importance of MSME owners on economic sustainability, literature on MSME owners' FS is lacking expressly among developing countries, particularly in Nigeria. This study also revealed new theoretical and practical knowledge by illuminating the mediating effect of AIF on AWIF–FS relationship.

This paper argues that cultures with the same climate have similar handicrafts as they have similar cultivation and identical raw materials. This study focuses on how mountainous, coastal and hot regions partaking in similar crafts and cultural heritage use palm leaves and analyses the resulting handicrafts' similarities.

A review of mapping these samples establishes this similarity in the traditional industries of some civilizations' cultural heritage from countries sharing similar climates.

The handwoven crafts using palm leaves were significant patrimonial artifacts in different societies' and communities' cultural heritage. Our studies revealed that climate plays an active role in influencing all aspects of humanity’s life. It affects the construction methods and style, agriculture and lifestyles.

Traditional handwoven palm leaf product models, especially plates and baskets, are studied from South America, Africa, Gulf Countries and Asia.

Additionally, this paper focuses on preserving these treasures as an essential part of interior elements as accessories for most inhabitants of these areas.

Cultural heritage also embraces intangible aspects such as skills passed down through generations within a particular society. The tangible and intangible elements complement each other and contribute to an overall legacy.

Cultural heritage reflects a society’s way of life carried down through the years across lands, items, customs and aesthetic concepts. People are the gatekeepers of society, as they preserve their way of life for future generations to emulate. Tangible artistic and cultural heritage comprises artifacts. It comprises all human evidence and expressions, such as traditional handicrafts, pictures, documents, books and manuscripts.

This paper aims to examine the antecedents of green entrepreneurship intention (GEI) amongst tourism and hospitality higher education students and further explores the effect of green entrepreneurship intention on sustainable development (SD). It also investigates the mediating role of GEI in the relationship between the antecedents of GEI and SD in students' future tasks in tourism and hospitality.

Partial least squares structural equation modeling was used to analyze data collected via an online questionnaire from 970 tourism and hospitality universities' students in Egypt, either undergraduate or postgraduate.

The results show that green entrepreneurship intention is positively affected by attitude, subjective norms, environmental education, risk aversion, self-efficacy and environmental values. The results also revealed that green entrepreneurship intention is a significant driver for sustainable development. Moreover, the findings revealed that GEI mediates the link between the antecedents of GEI and SD.

The results offer highly persuasive insights that may be used to promote GEI and SD among tourism and hospitality students. The effectiveness of GEI in achieving SD will motivate government and educational institutions to develop GEI for university students. This study will assist policymakers in developing a novel strategy, providing a contribution to the green behavior literature in an emerging context.

The field of the green entrepreneur is uncharted and still in its infancy. As a result, further research is needed in the literature to better understand green entrepreneurship intention. Enhancing tourism and hospitality students' green entrepreneurial intentions will help the economy expand sustainably in the future because they are the entrepreneurs of tomorrow. The findings hold important implications for both the research community and tourism education and business management.

This case study is most suitable for a target audience of graduate-level students in leadership and/or change management classes. It will help students to apply a change management model to an existing problem/change and analyze its applicability, recognize different leadership approaches in practice and assess their appropriateness in different contexts and present key findings and ideas in front of an audience.

This case study examines the leadership of Dr. Mahmoud Khattab, CEO of B.TECH, during the turbulent times of the 2011 Egyptian Revolution. B.TECH was founded in 1997 as a subsidiary of the Egyptian home appliances manufacturer Olympic Electric, to enter the retail market. The morning after January 28, 2011, the “Friday of Rage,” Khattab found the company’s stores looted and seized, and the employees panicked. The company leader was pressured to decide the next steps quickly. Everything was condensed into a dilemma of whether to keep the stores open but potentially risk employee trust and safety as well as the company’s assets – or close them but lose revenue, the ability to pay workers and the company’s market leader position. Students should also identify and reflect on the elements of leadership that contributed to a business success in a turbulent political environment. This case study highlights critical leadership and management decisions during an unexpected crisis that threatened the company’s operations and diversification efforts. Khattab acted almost instinctively, using the interpersonal and creative skills he had acquired while running a family business in his native Egypt and while occupying various leadership roles.

This case study is particularly suitable for classes on change management and leadership for university students at the graduate level.

This study investigated the effect of green marketing mix on consumer repurchase intention in Ghana. The study focusses on the interaction effect of green knowledge on green marketing mix and consumer repurchase in Ghana.

A quantitative approach to research was employed. In all, 371 participants were chosen using the purposive sampling technique. Data analysis was conducted using the SPSS software.

The findings showed that green price, green place and green promotion had a positive significant effect on repurchase intention. However, green product insignificantly influenced repurchase intention. The findings further showed that green knowledge moderated the relationship between green price and green place, on repurchase intention. Green knowledge was not found to moderate the relationship between green product, green promotion and repurchase intention.

The study advances our knowledge on green marketing mix, green knowledge and repurchase intention within the beverage sector. It reveals the positive implication of green marketing mix on a firm’s customers using the marketing mix theory.

This paper aims at explore the intervening role of servant leadership in tourism businesses' outcomes, in the context of travel agencies. Drawing on servant leadership theory, the authors develop a multimediation model exploring the relationships between servant leadership and person–job fit, work–life balance, work engagement, innovative work behavior and job crafting.

Using SmartPLS3, data collected from 942 travel agencies operating in Egypt, a questionnaire was used to obtain data on how travel agency employees envisage their organization’s adoption of servant leadership, person–job fit, job crafting, work–life balance, work engagement and innovative work behavior.

The authors show that servant leadership correlates positively with person–job fit, work–life balance, work engagement, innovative work behavior and job crafting, while job crafting correlates positively with work–life balance, work engagement and innovative work behaviors. The partial mediating roles of both job crafting and person–job fit in the link between servant leadership and work–life balance, and the partial mediating role of work engagement in the link between servant leadership and innovative work behaviors.

Up to date, research on the effects of servant leadership on person–job fit, job crafting, work–life balance, work engagement and innovative work behavior has been inadequate. In terms of contextual applicability, an empirical investigation of the relationship between these factors in travel agencies is not available. By empirically examining these relationships in the context of Egyptian travel agencies, the current study has bridged a gap in the tourism and hospitality literature, human resources management and organizational behavior literature.

本文旨在探讨仆人式领导在旅行社背景下对旅游企业成果的干预作用。借鉴仆人式领导理论, 我们开发了一个多重中介模型, 探索仆人式领导与人-工作契合度、工作-生活平衡、工作投入、创新工作行为和工作重塑之间的关系。

使用 SmartPLS3, 从在埃及运营的 942 家旅行社收集的数据, 使用问卷调查获取有关旅行社员工如何设想他们的组织采用仆人式领导、人-工作匹配、工作重塑、工作与生活平衡、工作参与和和 创新工作行为。

我们表明, 仆人式领导与人-工作契合度、工作-生活平衡、工作投入、创新工作行为和工作重塑呈正相关, 而工作重塑与工作-生活平衡、工作投入和创新工作行为呈正相关。工作重塑和个人-工作在仆人式领导与工作-生活平衡之间的联系中起部分中介作用, 工作投入在仆人式领导与创新工作行为之间的联系中起部分中介作用。

该研究进行了一些开创性的检查。迄今为止, 关于仆人式领导对人-工作契合度、工作重塑、工作-生活平衡、工作投入和创新工作行为的影响的研究还不够充分。就情境适用性而言, 尚无对旅行社中这些因素之间关系的实证研究。通过在埃及旅行社的背景下对这些关系进行实证检验, 当前的研究弥合了旅游和酒店文献、人力资源管理和组织行为文献中的空白。

El objetivo de este artículo es explorar el papel que desempeña el liderazgo de servicio en los resultados de las empresas turísticas, en el contexto de las agencias de viajes. Basándonos en la teoría del liderazgo de servicio, desarrollamos un modelo de mediación múltiple que explora las relaciones entre el liderazgo de servicio y la adecuación de la persona al trabajo, el equilibrio entre el trabajo y la vida personal, el compromiso laboral, el comportamiento laboral innovador y el diseño proactivo del puesto de trabajo.

Con SmartPLS3 se analizaron datos recopilados de 942 agencias de viajes que operan en Egipto mediante un cuestionario con el que se obtuvo información sobre cómo los empleados de agencias de viajes prevén que su organización adopte el liderazgo de servicio, el ajuste persona-trabajo, el diseño proactivo del puesto de trabajo, el equilibrio entre el trabajo y la vida personal, el compromiso laboral y el comportamiento laboral innovador.

Mostramos que el liderazgo de servicio se correlaciona positivamente con el ajuste persona-trabajo, el equilibrio entre el trabajo y la vida personal, el compromiso laboral, el comportamiento laboral innovador y el diseño proactivo del puesto de trabajo, mientras que el diseño del puesto de trabajo se correlaciona positivamente con el equilibrio entre la vida laboral y personal, el compromiso laboral y los comportamientos laborales innovadores. Mostramos también el papel mediador parcial del diseño proactivo del puesto de trabajo y del ajuste persona-trabajo, en el vínculo entre el liderazgo de servicio y el equilibrio entre el trabajo y la vida personal, asi como el papel mediador parcial del compromiso laboral en el vínculo entre el liderazgo de servicio y los comportamientos laborales innovadores.

Hasta la fecha, la investigación sobre los efectos del liderazgo de servicio en la adecuación de la persona al trabajo, el diseño proactivo del puesto de trabajo, el equilibrio entre el trabajo y la vida personal, el compromiso laboral y el comportamiento laboral innovador ha sido insuficiente. En términos de aplicabilidad contextual, no se disponía de una investigación empírica de la relación entre estos factores en las agencias de viajes. Al examinar empíricamente estas relaciones en el contexto de las agencias de viajes egipcias, el presente estudio cubre un vacío en la literatura sobre turismo y hostelería, gestión de recursos humanos y comportamiento organizacional.

The shift in consumer focus towards green marketing mix elements is not a unique thing. Especially in recent times, most organizations are trying to implement green marketing strategies in order to influence customers as well as to reduce the negative impacts of environmental footprints. However, in recent times service marketing requires thorough implementation of a Green Marketing Mix as evidenced by Asian countries. However, research also claims that the use of a traditional green marketing mix is not a guarantee of success in the long run and therefore has been criticized by several researchers and scholars. Hence, there is a need to follow the Green-SIVA (Solution, Information, Access, and Value) concept in order to create a long-lasting impact on consumer buying and to discuss the application of tools in a more comprehensive manner. Although the linkage of Green-SIVA marketing might provide a new way to develop an effective marketing mix strategy for services. Hence, this chapter has been written purposely to discuss GMM elements with reference to the service industry of Pakistan and tries to develop an association with green-SIVA marketing practices in order to optimize service marketing practices.

One of the challenges encountered in the design of guided projectiles is their prohibitive cost. To diminish it, an appropriate avenue many researchers have explored is the use of the non-actuator method for guiding the projectile to the target. In this method, biologically inspired by the flying concept of the single-winged seed, for instance, that of maple and ash trees, the projectile undergoes a helical motion to scan the region and meet the target in the descent phase. Indeed, the projectile is a decelerator device based on the autorotation flight while it attempts to resemble the seed’s motion using two wings of different spans. There exists a wealth of studies on the stability of the decelerators (e.g. the mono-wing, samara and pararotor), but all of them have assumed the body (exclusive of the wing) to be symmetric and paid no particular attention to the scanning quality of the region. In practice, however, the non-actuator-guided projectiles are asymmetric owing to the presence of detection sensors. This paper aims to present an analytical solution for stability analysis of asymmetric decelerators and apprise the effects of design parameters to improve the scanning quality.

The approach of this study is to develop a theoretical model consisting of Euler equations and apply a set of non-dimensionalized equations to reduce the number of involved parameters. The obtained governing equations are readily applicable to other decelerator devices, such as the mono-wing, samara and pararotor.

The results show that the stability of the body can be preserved under certain conditions. Moreover, pertinent conclusions are outlined on the sensitivity of flight behavior to the variation of design parameters.

The analytical solution and sensitivity analysis presented here can efficiently reduce the design cost of the asymmetric decelerator.

This paper aims to examine the extent to which these reforms address the limitations of Saudi Arabia’s previous investment framework. Long viewed as a hostile environment in which to do business, the Saudi Government has enacted a broad sweep of measures aimed at restoring investor confidence in central aspects of the country’s evolving private law framework.

This paper offers a timely assessment of the raft of foreign investment reforms, both legislative and regulatory, that have been introduced in Saudi Arabia over the last decade.

The paper will proceed by outlining the perceived failings of the old investment regime before going on to reforms.

It will consider the remaining obstacles to the flow of foreign investment in Saudi Arabia in the context of the dual forces that have historically defined the Kingdom’s ambivalent investment law regime.
