This study delves into the critical issue of banks' stability and profitability, which are crucial elements for fostering economic growth and preserving depositor confidence. Specifically, we scrutinize the impact of geopolitical risks on the profitability and solvency of banks operating in emerging economies across the Middle East and Africa.

Employing a two-step Generalized Method of Moments (GMM) approach, we analyze a comprehensive dataset comprising 125 banks spanning 13 emerging economies in the Middle East and Africa, covering the period from 2003 to 2019.

Our study reveals a significant sensitivity of Middle Eastern banks to geopolitical risks, wherein effective anticipation or adaptation to these risks positively influences bank performance. Conversely, the impact of geopolitical risk on African banking profitability appears inconclusive and statistically insignificant. These nuanced findings underscore the complex interplay between geopolitical dynamics and financial performance in diverse regional contexts, with implications for policymakers and industry stakeholders.

Our findings underscore the need for nuanced policy responses and risk management strategies tailored to the unique challenges posed by geopolitical dynamics in emerging markets. Furthermore, they highlight the importance of continued research efforts to deepen our understanding of these complex interactions and inform more effective decision-making in the financial sector.

Amidst growing recognition of the importance of geopolitical risks in financial markets, empirical studies exploring their precise impact on bank performance remain scarce. This study fills this gap by offering a pioneering investigation into the influence of geopolitical risks on bank profitability and solvency, using advanced econometric techniques and a substantial, diverse sample of banks in emerging economies across the Middle East and Africa.

The purpose of this paper is the investigation of a new coordinated switching strategy to improve the transient performance of a fuel cell (FC)- supercapacitor (SC) electric vehicle. The proposed switching strategy protects FCs from large currents drawn during abrupt power variations. Furthermore, it compensates the poor FC transient response and suppresses the transient ripples occurring during power source switching instants.

Coordinated power source switching is achieved using three different transition functions. Vehicle model is fractioned into computational and console subsystems for its simulation using real time (RT) LAB simulator. Blocs containing coordination switching strategy, power sources models and their power electronics interface are placed in the computational subsystem that will be executed, in RT, on one of real time laboratory simulator central processing unit cores.

Coordination switching strategy resulted in reducing transient power ripples by 90% and direct current (DC) bus voltage fluctuations by 50%. Switching through transition functions compensated the difference between FC and SC transient responses responsible for transient power ripples. Among the three proposed transition functions, linear transition function resulted in the best transient performances.

The proposed coordinated switching strategy allows the control of the switching period duration. Furthermore, it enables the choice of adequate transition functions that fit the dynamics of power sources undergoing transition. Also, the proposed switching technique is simple and does not require the knowledge of system parameters or the complex control models.

This study aims to propose a national frame of reference for the accreditation of engineering programs (EPs) in Tunisia. It uses as a benchmark the structure used by the world’s leading accreditation systems such as the Accreditation Board for Engineering and Technology (ABET) and Commission des Titres d’Ingénieur. It provides a comprehensive framework for academic institutions to evaluate the performance of their programs. In addition, it suggests the procedures, steps and timeline for the application process and defines the required documents that should be submitted.

The study analyzes the standards applied by well-established accreditation agencies such as ABET, Commission Titre Ingenieur and European Accredited Engineer, studies the perceptions of academicians who participated in six workshops and uses the results of surveys and interviews to characterize their opinions about accreditation. A sample population of 146 faculty members, experts and policymakers from 23 different higher education institutions in Tunisia, who had participated in the workshops mentioned above, was solicited to participate in the survey. The opinions of 51 respondents who responded to the survey were analyzed. This methodology led to the establishment of a proposed national frame of reference for accreditation of EPs.

Analysis reveals that the Ministry of Higher Education and Scientific Research (MHESR) provides authorization (“habilitation”) to institutions allowing them to offer their educational program. However, it is inaccurate to consider this procedure as accreditation because it is more of a licensure process. In addition, the MHESR grants the “habilitation” to those institutions that successfully apply. The National Authority for Assessment, quality assurance and accreditation Instance Nationale de l’Evaluation, de l’Assurance Qualité et de l’Accréditation (IEAQA) is not involved in this process, which makes the latter’s role trivial.

This frame of reference will help the MHESR to evaluate the EPs based on a comprehensive analysis of well-established accreditation systems, to improve its “habilitation” process by splitting it into two parts as per international practice, namely, licensure and accreditation and to make the existence and role of the IEAQA much clearer.

This study is the foremost study to propose a comprehensive frame of reference for accrediting EPs in Tunisia.

The purpose of this paper is to introduce a novel intensity-modulated fiber optic sensor for real-time intrusion detection using a fiber-optic microbend sensor and an optical time-domain reflectometer (OTDR).

The proposed system is tested using different scenarios using person/car as intruders. Experiments are conducted in the lab and in the field. In the beginning, the OTDR trace is obtained and recorded as a reference signal without intrusion events. The second step is to capture the OTDR trace with intrusion events in one or multiple sectors. This measured signal is then compared to the reference signal and processed by matrix laboratory to determine the intruded sector. Information of the intrusion is displayed on an interactive screen implemented by Visual basic. The deformer is designed and implemented using SOLIDWORKS three-dimensional computer aided design Software.

The system is tested for intrusions by performing two experiments. The first experiment is performed for both persons (>50 kg) in the lab and cars in an open field with a car moving at 60 km/h using two optical fiber sectors of lengths 200 and 500 m. For test purposes, the deformer length used in the experiment is 2 m. The used signal processing technique in the first experiment has some limitations and its accuracy is 70% after measuring and recording 100 observations. To overcome these limitations, a second experiment with another technique of signal processing is performed.

The system can perfectly display consecutive intrusions of the sectors, but in case of simultaneous intrusions of different sectors, which is difficult to take place in real situations, there will be the ambiguity of the number of intruders and the intruded sector. This will be addressed in future work. Suitable and stable laser power is required to get a suitable level of backscattered power. Optimization of the deformer is required to enhance the sensitivity and reliability of the sensor.

The proposed work enables us to benefit from the ease of implementation and the reduced cost of the intensity-modulated fiber optic sensors because it overcomes the constraints that prevent using the intensity-modulated fiber optic sensors for intrusion detection.

The proposed system is the first time long-range intensity-modulated fiber optic sensor for intrusion detection.

The purpose of this paper is to determine the need of Islamic Accounting Standards – a review of the literature – for Islamic financial institutions (IFIs).

The basis of the paper was stakeholder theory to analyse the need of accounting standards and to design the conceptual framework as evidenced from Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI). The evidence reviewed suggests the need for Islamic accounting standards to fill the gap in accounting practice among Islamic financial institutions.

The AAOIFI accounting standards serve as a guideline that may reflect the unique characteristics of IFIs and become a useful tool to meet the various needs of IFIs. Currently, one of the major challenges facing IFIs lies in the preparation of the financial statements under different accounting standards and which may lead to problems of comparability, reliability and compliance level measurement. This has resulted in a heated debate among scholars which has hitherto translated to the evolving existing literature surrounding the interpretation of the level of compliance with the Islamic accounting standards. The paper concludes with various recommendations for future research, the most important of which is the need for future studies on how AAOIFI accounting standards can be made mandatory in all Muslim countries.

This paper contributes towards a better understanding and acceptability of the need of Islamic Accounting Standards.

This study aims to test the role of the state of occupation, represented in Israel, as one of the most significant challenges, which faces the Jordanian water security. Where Israel expands in its policy and ideology everyday its hydro-hegemony over the Jordanian waters. Hence, its acts result in negative consequences on the Jordanian water and food security, which in turn affects the Jordanian national security as a whole.

This study relied on the following two approached to tackle its problem: first: descriptive approach: the descriptive approach depends on defining the apparent features and describing their nature and the type of the relationship between its variables. It aims to achieving a better and deeper understanding on the situation of its future policies and measures. And research uses the system analysis approach to handle the subject matter. Given the influence of water on the development, Jordan, as an organic or a political and social state, takes into account the reasons and causes of development. Jordan turns into an active political state, with water as an influencing factor on it. This premise represents the core of the system analysis approach.

The research concluded that the Israeli theft of the Jordanian waters is the main factor in the Jordanian water crisis. If Jordan had received its usurped water rights by Israel, it could have been able to solve its water issue represented in the increasing deficit in its water balance. Therefore, the Israeli hydro-hegemony on the Jordanian water resources caused the imbalance in its water security and, in turn, caused the development process to falter in general.

The value of the research lies in the fact that it addresses the most important reasons behind the water crisis in Jordan, represented in the Israeli control over the Jordanian water resources and the research shows that the amount of water stolen by Israel is enough to solve the water crisis in Jordan.
