Self‐service food stores are a new emerging form of retail technology in Saudi Arabia. By focusing on relevant institutional, planning and operational dimensions, this exploratory study describes and analyses the process by which this form of food retailing was adopted. Data were collected from 96 stores located in three metropolitan areas of the Kingdom, and the results suggest that the sudden proliferation of these stores during the past decade was characterised by the lack of rational planning, short‐term decision making orientation, and limited concern for promotional activities. The analysis of the 62 study variables indicated that differences in store size exerted limited influence on store marketing activities and had a moderate effect on store planning and institutional dimensions.

This paper aims to review the critical challenges and factors influencing the successful adoption of electronic learning (e-learning) systems in higher educational institutions before and during the current propagation of the coronavirus disease 2019 (COVID-19) pandemic.

This study undertook a literature review concerning the in-depth revision of previous studies published in 2020 and 2021. A total of 100 out of 170 selected research papers were adopted to identify and recognise the factors restricting the application of e-learning systems.

The findings determine and illuminate the most challenging factors that impact the successful application of online learning, particularly during the wide propagation of the COVID-19 pandemic. The review of the literature provides evidence that technological, organisational and behavioural issues constitute significant drivers that frontier the facilitation of the e-learning process in higher educational institutions.

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 examine a research model that links knowledge sharing enablers, processes and outcome dimensions in law enforcement in the United Arab Emirates (UAE). It attempts to examine the impact of knowledge self-efficacy and top management support on knowledge donating and collecting. It also attempts to examine the effect of these two aspects of knowledge sharing on firm innovation capability.

This study used a quantitative approach, with data collected by questionnaire from 685 police officers in a law enforcement agency in the UAE.

Knowledge self-efficacy and top management support have a positive impact on knowledge donating and collecting. Only knowledge collecting, however, had a positive effect on firm innovation capability.

The study has significant academic and practical implications. It supports a previous research model that links enablers, processes and outcomes of knowledge sharing, and confirms them in the context of law enforcement in the UAE. It could also help law enforcement agencies to promote a knowledge sharing culture to support innovation in the UAE.

The research model is likely to be particularly valuable in knowledge-intensive organizations such as the law enforcement sector. Knowledge sharing is often overlooked by organizations in the UAE because there has to date been little research in this field.

The concept of e-learning is essential in employee education since it provides different ways to develop employees' knowledge, skills and attitudes using modern technologies. E-learning has been overgrowing in employee education because learning can be held anytime and anywhere. In order to succeed in implementing e-learning and benefiting from its capacities, and avoiding potential threats in the country, it is necessary to address the factors affecting its success. This paper aims to test the role of internet of Things (IoT)-based systems, cloud-based services, virtual classes, evaluation tools, attitude, content management and creativity on the success of employees' e-learning programs based on a framework.

E-learning systems receive ever-increasing attention in academia, business and public administration. With the development of e-learning, employee education has also benefited from its capacities in various fields. To succeed in implementing e-learning and benefiting from its capacities, and avoiding potential threats in the country, it is necessary to address its success. The proposing of Information and Communications Technology (ICT)-based technologies such as the IoT, cloud, etc., in e-learning, can help transform education. Therefore, this paper aims to test the role of IoT-based systems, cloud-based services, virtual classes, evaluation tools, attitude, content management and creativity on the success of employees' e-learning programs based on a framework. The research model and the data collected from the questionnaires have been analyzed via Smart PLS 3.2. This study has utilized the SEM to evaluate the causal model's reliability and validity based on measurement. According to the literature in this study, a framework has been proposed that examines the impact of IoT-based systems, cloud-based services, virtual classes, evaluation tools, attitude, content management and creativity on employees' learning programs' success.

The results have shown that IoT-based systems, cloud-based services, virtual classes and evaluation tools are four significant factors affecting attitude, content management and creativity. The results have also shown that attitude, content management and creativity are three significant factors affecting employees' learning programs' success. The factors above are considered critical in explaining the success of employees' e-learning programs, but, as far as we know, there has been no study in which all these factors were demonstrated together.

From a practical viewpoint, the statistical outcomes support the important role of the following factors: IoT-based systems, cloud-based services, virtual classes, evaluation tools, attitude, content management and creativity. Henceforth, aspects relating to these factors got the attention of any organization to develop e-learning processes.

This research will contribute to the literature related to employees' e-learning programs' success by integrating all the mentioned variables. As far as we know, it is the first study to test these variables in Iran.

The purpose of this article is to investigate on changes of the microbial load and the chemical and physical properties of date fruits stored for 6 months under two different temperatures.

A composite sample of 100 kg date fruits from the Khalas variety, season 2019, was collected from the local market in Al Ahsa Province, Saudi Arabia, packaged in 1 kg lots, stored at room and refrigerator temperatures and the microbial contamination and the chemical and physical properties monitored over a period of six months of storage. Total bacteria, lactic acid bacteria, Enterobacteriaceae, yeasts and molds were counted and representatives of yeast and mold contaminants were identified using morphological, physiological and molecular typing techniques. Changes in the color and texture of the samples were also monitored during storage.

The yeasts detected were two strains of each of Lachancea thermotolerans and Rhodosporidiobolus fluvialis and one strain of Cystofilobasidium lacus-mascardii. For molds, one strain of each of Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum and Aspergillus caespitosus have been detected. No significant growth of these microorganisms was observed, but enough load persisted during storage that makes the samples not meeting the microbiological standards. There were significant changes in the color and texture of the fruits during storage.

These findings add important information that can help producers and processors to improve quality and promote marketing of date fruits, especially to international markets.

The purpose of this paper is to examine the impact of leadership and rewards on the contribution to knowledge sharing in public organizations of the United Arab Emirates (UAE).

Data were collected from 154 employees from various organizational units of a law enforcement organization in the UAE, and structural equation modeling was used to test the proposed hypotheses.

Leadership inspiration was found to be positively effective in enhancing the contribution of knowledge sharing in terms of solving problems, increasing opportunity and improving the productivity of the workforce. Furthermore, it was found that the reward system had no impact on the contribution to knowledge sharing.

The method of data collection focused on the employees who were attending a training workshop in the department. This survey raises concerns related to non-response bias and common method bias, which describes the measurement error that is compounded by the sociability of the respondents who wanted to provide positive answers.

This research focuses on the implementation of certain practices related to knowledge sharing in public organizations. The model was constructed to assess the impact of leadership and rewards on the contribution to knowledge sharing through knowledge sharing practices as a mediation. The study is a modest attempt to assist the organizational leaders to embark on the right steps to foster knowledge sharing behavior among employees.

The study contributes to the literature on knowledge sharing, particularly on the relationship between leadership inspiration, rewards and contribution to knowledge sharing in the law enforcement organizations in the UAE.

In the construction industry, cash flow issues can impact both contractors and owners. Although finance-based scheduling (FBS) models were developed to control contractors’ cash flow, researchers completely disregarded cash flow management for owners’ portfolios. Therefore, FBS is once again introduced in this study from the perspective of the owners of portfolios.

For the FBS problem of portfolio owners (FBS-PO), a mixed integer linear program (MILP) model is developed. The purpose is to ensure that owners’ cash inflows are greater than cash outflows while minimizing the sum of weighted extensions of the projects in portfolios. Owing to the difficulties encountered in solving the proposed MILP model, genetic algorithm (GA) and particle swarm optimization (PSO) meta-heuristics are used. To ensure the feasibility of the solutions, a special serial schedule generation heuristic was developed in conjunction with the random key method for chromosome representation.

The GA produced higher-quality solutions compared to PSO, though it required more processing time. The GA has proven to be a far better choice than the MILP exact solver for bigger portfolios. Additionally, there is a linear correlation between the number of activities in portfolios and the amount of computational time required for the GA to converge.

This paper introduces the new research domain of FBS from the owners’ perspective (FBS-PO). In order to establish the FBS-PO as a stand-alone domain, a critical review of the FBS studies in the literature was conducted. In addition, the goals, characteristics, implementation and challenges of the FBS heuristics are benchmarked against those of the special serial schedule generation heuristic developed for the FBS-PO problem.

The purpose of this paper is to attempt to introduce a new approach to User's Informational‐Based Readiness (UIBR) for investigating the acceptance of marketing innovations such as Internet Banking (IB) services.

The UIBR construct involves four dimensions that it is proposed influence the potential adopters' intention to adopt IB. The study employed the quantitative method where convenience sampling and self‐administrated survey questionnaires were sent to 1,000 bank account holders in Yemen.

The findings reveal that both intention and attitude are positively related to all variables of interest and are significantly related to all investigated variables. Furthermore, the multiple regression findings moderately supported that all alternative hypotheses of interest and their sub‐hypotheses are accepted, regarding both the individual's intention and attitude towards the adoption of IB.

This study does not examine the formal relationship between Intention and Attitude and the sample size could have been larger.

The results strengthen the study's argument that the four UIBR dimensions significantly affect a person's intention and attitude towards IB‐use.

Previous studies that sought innovation adoption did not give much concern to the UIBR. This study makes a valuable contribution in the field of marketing by implementing the four UIBR components in the management area as a tool to evaluate the performance and marketing strategy of firms, and also to evaluate to what extent consumers are ready to accept the products or the services introduced.

This study aims to analyze the impact of Arab Revolution on the Arabian Gulf security by applying on Yemeni Revolution. This can be achieved by analyzing the threat of Arab Spring Revolutions to the national security of the Gulf Cooperation Council (GCC) countries after the breakout of demonstrations and protests in some of the member states. In addition to its analysis of threat of the Regional Security of the Gulf as a result of Yemeni Revolution and Civil War and Iranian intervention to support Houthis within light of regional anarchy and security competition according to the Neorealism and how the GCC Countries face such threats.

The study depended on the historical methodology to track the developments of some events related to the Gulf Security and crisis in Yemen. Moreover, it used the analytical approach to analyze the impact of Arab Revolutions and Yemeni Civil War on the Arab Gulf Security. In addition, it depended on the realistic approach to explain the security state at the national and regional level of the Arab Gulf countries within light of regional anarchy, security competition and Iranian support to Houthis “Non-State Actors” (Kenneth Waltz), as well as the offensive realism (John Mearsheimer).

The Arab Revolutions had an effect on the national security of GCC countries according to the Neorealism due to the breakout of demonstrations and protests in Saudi Arabia, Kuwait and Sultanate of Oman which reached to the degree of threatening the existence of the state as in Bahrain. The Gulf Regional Security is influenced by Revolution and Civil War in Yemen as a result of that Iranian support to Houthis within light of security competition between Iran and Saudi Arabia, leading to the threat of the Arabian Gulf Security as Yemen is the southern gate to the GCC Countries and having joint borders with Saudi Arabia and Sultanate of Oman. Moreover, the GCC countries dealt with that threat individually, such as, performing internal reforms, or collectively through using military force, such as Bahrain and Yemen (Offensive Realism).

This study is an introduction to explain the Arab Spring Revolutions, conflict in Yemen and its threat to the Arab Gulf Security according to the Neorealism based on that the GCC countries sought to keep its existence and sovereignty in confrontation to the demonstrations and internal protests and to keep the regional security in confrontation to the threats of neighboring countries such as the Civil War in Yemen and the Iranian Support to Houthis in light of the regional anarchy.
