Effects of home quarantine during COVID-19 lockdown on physical activity and dietary habits of adults in Saudi Arabia
Public health endorsements during the present COVID-19 pandemic has led the governments of largely affected countries to imply policies that restrict social mobility to slow COVID-19 spread. The study aimed to explore the effects of COVID-19 home quarantine on lifestyle and health behavior of Saudi residents. An online survey in Saudi Arabia was launched from May 11 to June 6, 2020. The survey was designed by multidisciplinary scientists and academics uploaded and shared through the Google platform in Arabic and English languages. Questions presented related to responses \"before\" and \"during\" COVID-19 home quarantine. A total of 1965 respondents participated and were included in the analysis [921 (47.0%) males and 1044 (53.0%) females]. Non-Saudis were more likely to increase their physical activity during quarantine [odds ratio (95% confidence interval 1.41 (1.11-1.79); p < 0.005]. Prevalence of participants walking daily for more than 4 times per week significantly decreased during pandemic (before vs during, 30.5% vs 29.1%) which was in parallel to the significant increase in the prevalence of participants who did not perform daily walking during the quarantine (21% vs 22.9%; p < 0.001). The prevalence of participants who often consume snacks between meals increased during quarantine (27.4% vs 29.4%, p < 0.001), while the prevalence of participants who never consumed fresh fruits and vegetables significantly increased during home quarantine (2.4% vs 3.7%; p = 0.019). The lockdown imposed in Saudi Arabia modestly but significantly impacted physical activity and dietary behaviors of several citizens and residents in an unhealthy way. Interventions to alleviate these acute adverse lifestyle behaviors during pandemic should be formulated.

Automatic recognition of handwritten Arabic characters: a comprehensive review
The paper is a comprehensive review of the current research trends in the area of Arabic language especially state-of-the-art approaches to highlight the current status of diverse research aspects of that area to facilitate the adaption and extension of previous systems into new applications and systems. The Arabic language has deep, widespread and unexplored scope to research although the tremendous effort and researches that had been done previously. Modern state-of-the-art methods and approaches with fewer errors are required according to the high speed of hardware and technology development. The focus of this article will be on the offline Arabic handwritten text recognition as it is one of the most important topics in the Arabic scope. The main objective of this paper is critically analyzing the current researches to identify the problem areas and challenges faced by the previous researchers. This identification is intended to provide many recommendations for future advances in the area. It also compares and contrasts technical challenges, methods and the performances of handwritten text recognition previous researches works. It summarizes the critical problems and enumerates issues that should be considered when addressing these tasks. It also shows some of the Arabic datasets that can be used as inputs and benchmarks for training, testing and comparisons. Finally, it provides a fundamental comparison and discussion of some of the remaining open problems and trends in that field.

How Islamic Business Ethics Impact Women Entrepreneurs: Insights from Four Arab Middle Eastern Countries
This study explores how Islamic business ethics and values impact the way in which Muslim women entrepreneurs conduct their business in the Arab world. Guided by institutional theory as a theoretical framework and social constructionism as a philosophical stance, this study uses a qualitative, interview-based methodology. Capitalizing on in-depth, face-to-face interviews with Muslim Arab women entrepreneurs across four countries in the Arab Middle East region, the results portray how Islamic work values and ethics are embedded in the entrepreneurial activities of these Arab women. The results also illustrate how Muslim women entrepreneurs seek well-being (falah) in their life and excellence (itqan) in their work while running their businesses. The Muslim women entrepreneurs adhered to the Islamic work-related values of good and hard work (amal salih), honesty and truthfulness (sidik and amanah), fairness and justice (haqq and adl), and benevolence (ihsaan) and perceived them as instrumental to the survival and success of their enterprises. The agency of the Muslim Arab women allowed them to construct and navigate their entrepreneurial careers away from the traditional, doctrinaire interpretations of Islam. This study, therefore, contributes to theory development on the interrelationship between gender and business ethics within entrepreneurial contexts and in relation to Muslim values. It also contributes to studies on entrepreneurship and business ethics by showing how Arab women practice entrepreneurship and project their faith in their enterprises. The implications of the study for academics, multinational corporations, and globalization are numerous and important for understanding how business is conducted in Islamic countries.

Southward shift of precipitation extremes over south Asia: Evidences from CORDEX data
Analysis of observed Indian Summer Monsoon precipitation reveals more increase in extreme precipitation (in terms of its magnitude) over south India compared to north and central India during 1971-2017 (base period: 1930-1970). In the future, analysis of precipitation from the Coordinated Regional Downscaling Experiment indicates a southward shift of precipitation extremes over South Asia. For instance, the Arabian Sea, south India, Myanmar, Thailand, and Malaysia are expected to have the maximum increase (~18.5 mm/day for RCP8.5 scenario) in mean extreme precipitation (average precipitation for the days with more than 99
percentile of daily precipitation). However, north and central India and Tibetan Plateau show relatively less increase (~2.7 mm/day for RCP8.5 scenario). Analysis of air temperature at 850 mb and precipitable water (RCP4.5 and RCP8.5) indicates an intensification of Indian Ocean Dipole in future, which will enhance the monsoon throughout India. Moisture flux and convergence analysis (at 850 mb) show a future change of the direction of south-west monsoon winds towards the east over the Indian Ocean. These changes will intensify the observed contrast in extreme precipitation between south and north India, and cause more extreme precipitation events in the countries like Myanmar, Thailand, Malaysia, etc.
