Does Corporate Governance Constrain Earnings Management in an Unstable Economic and Political Environment?

The purpose of this research is to examine the effects of corporate governance structures on earnings management behavior in a weakly governed and politically unstable environment. A panel of data from 35 non-bank companies listed on the Palestine Exchange between 2012 and 2019 was employed. A fixed effects regression model was used to examine the impact of certain board characteristics (board size, board meetings, and audit committee formation) and ownership structures (institutional ownership, foreign ownership, and ownership concentration) on earnings management in the volatile and risky political and economic environment of Palestine. The findings indicate that corporate governance and ownership systems in Palestine appear to be ineffective in constraining earnings management practices. None of the board attributes appear to constrain earnings management practices. However, there is weak evidence to show that ownership concentration has some effect in curbing earnings manipulation. The findings of this study are expected to increase awareness among Palestinian regulators, investors, and other policymakers regarding the role of boards of directors and institutional and foreign shareholders in monitoring Palestinian listed companies to enhance corporate governance and the quality of financial reporting

STRESS TESTING MQTT SERVER FOR PRIVATE IOT NETWORKS

The rapid development of the Internet of Things (IoT) and the wide area of application rise the IoT concept to be the future of the internet. Indeed, IoT environment has a special nature with a lot of constraints in term of resource consumption. Moreover, the data exchanged between things and the internet is big data. In order to achieve efficiency in IoT communication, many technologies and new protocols based on these technologies have been developed. This paper aims to study the performance of Message Queuing Telemetry Transport (MQTT) by implementing this protocol on test-bed network infrastructure and analyzing the performance properties such as delay jitter, packet loss and throughput for real time and non-real time scenarios. Finally, future research issues in MQTT protocol are suggested

Micro search engine for IoT: an IoT search engine prototype for private networks

Background: The Internet of Things (IoT) has been heralded as the “next big thing” waiting to be realized. IoT revolves around increased machine-to-machine communication and it encompasses various embedded sensorsand actuators that assist users in monitoring and controlling objects remotely in many fields and applications. Methods: IoT's special characteristics introduce challenges in the field of retrieval technology. These challenges constitute of real-time data retrieval with the huge amount of data that can be produced from the sensors. This paper explains the design concepts used to develop a search engine for IoT to tackle these issues. The developed search engine appears to be promising. The performance of the network proved very powerful under normal conditions, however, it could not sustain heavy load under the stress test due to the restricted build of the Z1 motes. Results: The searching capability proved to be quite strong in terms of searching speed and acceptable results; however more tests need to be implemented especially in terms of parallel searching. The GUI is simple and produces multiple features, but lacks interactivity. The security aspect ensures the security of the database with the partial prevention of SQL injection attacks. Conclusion: However, more security measures are required to protect against eavesdropping and unauthentic clients

Evaluation of Analgesic Activity of Papaver libanoticum

Papaver libanoticum is an endemic plant to Lebanese region (family Papaveraceae) that has not been investigated before. The present study aimed to explore the analgesic activity of dried ethanolic extract of Papaver libanoticum (PLE) using tail flick, hot plate, and acetic acid induced writhing models in mice. The involvement of opioid receptors in the analgesic mechanism was investigated using naloxone antagonism. Results demonstrated that PLE exhibited a potent dose dependent analgesic activity in all tested models for analgesia. The analgesic effect involved activation of opioid receptors in the central nervous system, where both spinal and supraspinal components might be involved. The time course for analgesia revealed maximum activity after three hours in both tail flick and hot plate methods, which was prolonged to 24 hours. Metabolites of PLE could be responsible for activation of opioid receptors. The EC50 of PLE was 79 and 50 mg/kg in tail flick and hot plate tests, respectively. The total coverage of analgesia by PLE was double that of morphine in both tests. In conclusion, PLE proved to have opioid agonistic activity with a novel feature of slow and prolonged effect. The present study could add a potential tool in the armaments of opioid drugs as a natural potent analgesic and for treatment of opioid withdrawal syndrome

The impact of cultural healthcare practices on Children’s health in the United Arab Emirates: a qualitative study of traditional remedies and implications

AimThis qualitative study investigates the impact of cultural practices on children’s health in the United Arab Emirates (UAE) by examining the use of traditional remedies and home treatments by mothers.MethodsTwenty-five participants, all mothers who had employed traditional treatments or home remedies for their children during periods of illness, were included in the study. The participants represented a diverse range of educational backgrounds, from school diploma holders to university degree graduates, with ages spanning from 20 to 50 years. Hailing from different Arabic countries and cultural subgroups, the majority of participating mothers were from the UAE.ResultsThrough in-depth interviews, three major themes emerged from the participants’ experiences. Firstly, a strong connection between culture, religion, and healthcare practices was evident. Many mothers opted for cultural remedies as their first line of defense against illnesses due to the practices’ strong foundations in their cultural heritage. Herbal remedies, Quranic healing, and other traditional methods were perceived to be both effective and spiritually comforting, reinforcing participants’ sense of cultural identity. Secondly, participants highlighted unintended consequences of relying solely on traditional treatments. Some instances were reported where the use of ineffective remedies resulted in delays in seeking appropriate medical care for their children, potentially compromising their health. Additionally, certain misconceptions regarding the safety and efficacy of traditional remedies were identified, emphasizing the need for evidence-based healthcare education.ConclusionThis qualitative study sheds light on the intricate interplay between culture, traditional remedies, and children’s health in the UAE. The incorporation of diverse participants from various Arabic countries and cultural subgroups enriches the study’s applicability to broader Arabic cultures. By recognizing the significance of cultural healthcare practices and striking a balance with evidence-based care, healthcare providers can create a more inclusive and effective healthcare environment for children in the UAE. Future research should explore diverse samples and develop targeted interventions to further advance cultural awareness and understanding in healthcare practices
