This study aims to investigate the relationship between the spread of extremist thoughts and the weak economic and social factors surrounding it. There are higher chances of better understanding of this relationship on Egypt’s borders more than its center. Achieving development and stability leads to creating a preventive environment to extremist thoughts existence and spread, in addition to preventing its transformation into terrorism.

The study depends on an analytical methodology to examine the validity of the research hypothesis through two basic steps. The first step depends on describing the geographical, demographical, economic, social, political and security aspects of North Sinai. The second step is a prospective approach to build a strategy that helps in achieving development and accordingly a comprehensive confront for the opportunities of extremist thought spreading in North Sinai.

The study concludes that Egypt is well aware of the dimensions of encountering extremist thoughts and has adopted a comprehensive approach in achieving this. It has already started the paces of this confrontation in general, with some specificity in North Sinai Governorate that observed lately increased activities by extremists and terrorist groups. The proposed strategy is a set of policies that can help the country achieve its goals against extremism and terrorism.

The study covers a time frame that starts from 2014, which is considered the beginning of a new phase for the Egyptian state. The study relies on the field of strategic studies and it focuses on North Sinai Governorate.

The study has a scientific importance because it presents a proposal for a comprehensive strategy to encounter extremist thoughts, which adds value to the literature of the study of extremism. The current study makes its contributions in some directions, such as reviewing the contents of this extremist thought or the juristic comment on it, the impacts of the spread of extremist thoughts, the role of the official media in disseminating extremist thoughts or standing up to it. In terms of application, the study presents a proposal with many policies in various fields to counter extremist ideology. These proposals are implementable in North Sinai Governorate as well as other frontier governorates.

Waqf (Islamic endowment) in the form of cash is important to address the problem of developing idle waqf lands. Although there are various existing models of cash waqf, there is still a need for innovative cash waqf models. This paper aims to offer an alternative mode of financing for developing idle waqf lands using the concepts of cooperatives and waqf.

The present study first evaluates relevant literature on financing issues faced by waqf institutions in developing idle waqf lands as well as existing models of cash waqf. Based on the prevailing gap in cash waqf models, the study proposes a hybrid model of cooperative-waqf to finance idle waqf lands in Malaysia.

The proposed model is unique owing to the new dimension of membership being embedded into the waqf project. It considers donors as members of the waqf project, which is funded through the cash waqf collected, and thus, donors are given the privilege to receive benefits from the commercialised projects that are developed on the waqf lands. The existing models of cash waqf use traditional methods in which donors merely contribute cash waqf without any awareness of how the contributions are utilised. Usually, this problem occurs due to the lack of reciprocal communication between cash waqf donors and waqf institutions.

The present study examines the case of waqf land development in the context of Malaysia only. Secondly, the paper does not contain any empirical analysis, and the development of the paper is based on existing literature that discusses various models of cash waqf practised in Muslim-majority and -minority countries. Future research can conduct surveys of donors and other stakeholders on the practicality of the model.

It is expected that the proposed cooperative-waqf model will be able to create a synchronised relationship between cash waqf donors and waqf institutions and hence boost participation in developing waqf lands.

The present study adds to the existing literature in the area of waqf and cash waqf models, especially the application of this instrument in the context of Malaysia. It also offers a new hybrid model to the State Islamic Religious Councils (SIRCs) – Malaysia’s sole trustee of waqf assets management – such that the implementation of the proposed model could boost the collection of cash waqf in developing commercial projects on idle waqf lands.

The purpose of this paper is to draw a map of the general features of epistemological and critical concerns in contemporary Islamic philosophy. This study will not be confined to the domain of academic philosophy or to those who are professionals in the field of philosophy.

The paper adopted the critical rational approach in dealing with contemporary Islamic philosophy in the Arab world. The scope will include scholars from different fields of epistemology who tried to present a “vision” of the attitude that should be adopted in facing the challenges of the age and the problems of the nation on the epistemological level or the political, economic and social levels.

There is a need for a philosophy of action and progress rather than a philosophy that is based on abstract ideas and theories and of words/rhetoric. The ethics required to accomplish this ought to identify the attributes of the citizen who can reach self-actualization through legitimate means based on a progress agenda with theoretical and philosophical foundations.

Because a critical rational approach can be dealt with from different perspectives, this paper will adopt the classification of the principal intellectual trends: the reformist, secular and liberal.

This paper covers a long time span to determine whether the philosophical projects have been effective.

This paper, which criticizes the philosophic projects that are theoretically unsound and that do not address real social problems (like poverty), argues the need for a philosophy of progress and action. This will lead to devising an agenda that addresses the challenges the society is facing and to finding alternative and creative solutions resulting in development.

This paper aims to analyze the Egyptian revolution as an anti-systemic movement. It illustrates how Egypt’s position in the world-economy has affected its political economy orientation and led to the marginalization of critical masses, who launched the revolution.

The paper follows Wallerstein’s world-system analysis focusing on the anti-systemic movement concept. The paper analyzes the Egyptian case based on Annales school’s longue durée concept, which is a perspective to study developments of social relations historically.

The Egyptian revolution was not only against the autocratic regime but also against the power structure resulting from the neoliberal economic policies, introduced as a response to the capitalism crisis. It represented the voice of the forgotten. The revolution was one of the anti-systemic movements resisting the manifestations of the capitalist world-economy.

This paper aims at proving that the Egyptian revolution was an anti-systemic movement; which will continue to spread as a rejection to the world-system and to aspire a more democratic and egalitarian world. The current COVID-19 pandemic is exacerbating the crisis of the world-system.

This paper explores the effect of perceived service quality, trust, perceived value and perceived cost on patient satisfaction and loyalty as well as exploring the moderating role of the sociodemographic factors.

The data were gathered from 462 patients via a structured questionnaire, while structural equation modeling was utilized for the analysis.

Results indicated that trust, perceived value and patient satisfaction have important roles in shaping the patient loyalty, while patient satisfaction was found to fully mediate the patient’s perceived service quality. Loyalty relationship was also found to partially mediate the trust–loyalty relationship. Nonetheless, the patient’s satisfaction–loyalty relationship was found to be only moderated by the age factor.

Implications are provided to the Egyptian private hospitals in order for them to formulate improvement plans as well as set higher standards of conduct.

This original research is the first one, up to the researcher knowledge, that explores the drivers of patient satisfaction in the private hospitals in Egypt.

This study aims at investigating the extent of SysTrust’s framework (principles and criteria) as an internal control approach for assuring the reliability of accounting information system (AIS) were being implemented in Jordanian business organizations.

The study is based on primary data collected through a structured questionnaire from 239 out of 328 shareholdings companies. The survey units were the shareholding companies in Jordan, and the single key respondents approach was adopted. The extents of SysTrust principles were also measured. Previously validated instruments were used where required. The data were analysed using t-test and ANOVA.

The results indicated that the extent of SysTrust being implemented could be considered to be moderate at this stage. This implies that there are some variations among business organizations in terms of their level of implementing of SysTrust principles and criteria. The results also showed that the extent of SysTrust principles being implemented was varied among business organizations based on their business sector. However, there were not found varied due to their size of business and a length of time in business (experience).

This study is only conducted in Jordan as a developing country. Although Jordan is a valid indicator of prevalent factors in the wider MENA region and developing countries, the lack of external validity of this research means that any generalization of the research findings should be made with caution. Future research can be orientated to other national and cultural settings and compared with the results of this study.

The study provides evidence of the need for management to recognize the importance of the implementation of SysTrust principles and criteria as an internal control for assuring the reliability of AIS within their organizations and be aware which of these principles are appropriate to their size and industry sector.

The findings would be valuable for academic researchers, managers and professional accounting to acquire a better undemanding of the current status of the implementation of the SysTrust principles (i.e., availability, security, integrity processing, confidentiality, and privacy) as an internal control method for assuring the reliability of AIS by testing the phenomenon in Jordan as a developing country.

The purpose of this study is to unearth the factors that influence tourists’ revisit intention. The proposed model of the study is grounded on using the theory of planned behaviour (TPB) and extending it with additional variables, i.e. satisfaction, destination image, perceived risk, service quality and perceived value.

This study adopted a cross-sectional approach to collect data. The data were collected by conducting a field survey questionnaire on 330 respondents and were analysed using partial least squares version 3.2.9.

The results show that perceived behavioural control, perceived value, destination image and satisfaction significantly affect visitors’ revisit intention. The influence of perceived value, perceived service quality and destination image on satisfaction is also confirmed. On the other hand, satisfaction is found to be a significant mediator between perceived service quality, destination image and perceived value.

The extended TPB model that includes perceived service quality, perceived value, perceived risk and satisfaction provided a model with a theoretical basis to explain tourist revisit intentions to a tourist destination.

El objetivo principal del estudio es descubrir los factores que influyen en la intención de revisita de los turistas. El modelo propuesto para el estudio se basa en el uso de la teoría del comportamiento planificado y se amplía con variables como la satisfacción, la imagen del destino, el riesgo percibido, la calidad del servicio y el valor percibido.

Este estudio adoptó un enfoque transversal para la recogida de datos. Los datos se recopilaron mediante un cuestionario de campo en el que participaron 330 encuestados. Los datos se analizaron utilizando la versión 3.2.9 de PLS.

Los resultados muestran que el control conductual percibido, el valor percibido, la imagen del destino y la satisfacción afectan significativamente a la intención de revisita. También se confirma la influencia del valor percibido, la calidad de servicio percibida y la imagen del destino sobre la satisfacción. Por otra parte, la satisfacción resulta ser un mediador significativo entre la calidad de servicio percibida, la imagen del destino y el valor percibido.

El modelo TPB ampliado que incluye la calidad de servicio percibida, el valor percibido, el riesgo percibido y la satisfacción proporcionó un modelo con una base teórica para explicar las intenciones de revisita de los turistas a un destino turístico.

This study aims to examine the moderator effect of religiosity on the relationship between halal brand awareness and habit towards purchasing decisions of halal products.

The quantitative method is used in this study. Descriptive and statistical (multiple and moderated regression) analyses are employed to test the hypothesis according to the research model. The data is collected using a cross-sectional design from 197 respondents consisting of business owners in North Sumatera, Indonesia.

It is found that both halal brand awareness and habit have a positive and significant effect on the purchasing decision of halal products. Meanwhile, religiosity significantly acts as a moderating variable in the relationship between awareness and purchasing decisions, as well as habit and purchasing decisions.

This study revealed the important factor of religiosity as a moderating factor in purchase decisions of halal products. The government may need to collaborate with Islamic educational institutions to raise awareness of the halal concept and product awareness. It is assumed that individuals who know about the Islamic religion will have a higher degree of awareness of halal products compared to individuals with limited knowledge of Islam; thus, providers of Islamic education play a crucial role in raising the level of awareness of halal products. Schools may serve as catalysts for the dissemination of knowledge of halal products.

Developing halal product markets can be done by enhancing the religiosity level of consumers, one of them through attending formal or informal religious classes.

The aim was not to perform a systematic review but firstly to search in PubMed, Science Direct, Scopus and Web of Science databases on the papers published in the last five years using tools for reviewing the statement of preferred information item for systematic reviews without focusing on a randomized analysis and secondly to perform a bibliometric analysis on the properties of films and coatings added of tocopherol for food packaging.

On January 24, 2022, information was sought on the properties of films and coatings added of tocopherol for use as food packaging published in PubMed, Science Direct, Scopus and Web of Science databases. Further analysis was performed using bibliometric indicators with the VOSviewer tool.

The searches returned 33 studies concerning the properties of films and coatings added of tocopherol for food packaging, which were analyzed together for a better understanding of the results.
