Four Levels

This study analyzes the content of 12th-grade mathematics textbooks and workbooks, based on their inclusion of mathematical discourse components. The mathematics textbooks and workbooks were used in a Saudi Arabian school, where students are transitioning from secondary education to university. The results revealed that Saudi Arabian school textbooks and workbooks did not appropriately include discourse components or discourse skills to help facilitate mathematical learning among students. Furthermore, these textbooks did not exceed level two of the four levels of inclusion. As a result, the inclusion was insufficient in helping students meaningfully understand mathematical concepts, become active students, and develop successful community leadership. This implies that mathematics textbooks and workbooks should be revised to include mathematical discourse so that this inclusion is more student directed than teacher directed.

This paper concerns a probable shipwreck cargo of Aqaba amphorae, which was discovered during the second season of the survey project along the Saudi Arabian coast, initiated by nautical archaeologists of Philipps-University Marburg and conducted in cooperation with members of the Saudi Commission for Tourism and Heritage in autumn 2013. Seafaring and sea trade was, according to the few ancient sources and modern research activities, a hazardous endeavor in antiquity. Transport containers like the Aqaba Amphorae played a major role in sea trade, a significant number of which have been detected on various sites along the Red Sea coast and its hinterland. The chronological classification as well as the application is far from complete, and recent archaeometrical investigations help to clarify the logistical aspects of manufacturing and distribution of Aqaba amphorae. Finding a number of remains of Aqaba amphorae at a supposed shipwreck site close to Jeddah delivers new insight into the maritime routes and activities along the western coast of Saudi Arabia. The documentary material currently available is the baseline for further research in the field of maritime archaeology as it pertains to trade in the Red Sea.

Construction Accidents

Introduction: Research indicate that construction site accidents are a global concern, and rates are rapidly increasing. In developing countries such as Saudi Arabia, safety issues are frequently ignored, and little is known about their causes. Objectives: This study aimed to shed light on factors causing accidents in Saudi Arabian construction companies. Methods: An online detailed survey, using Google Form, of accident features was distributed randomly to potential employees in 35 construction companies in Saudi Arabia, where one of the top administrators or safety officers were required to respond to the survey. It was conducted from 1st June to 31st August, 2013. The safety practices and perceptions of accident causes were assessed. Results: The response rate was 63%. Over half of the surveyed organizations encountered all of the selected accident types. While 19 (86%) of the construction companies maintained the equipment regularly, 15 (68%) had regular maintenance staff and 13 (59%) inspected the equipment before use. Although 18 (82%) of the workers were supplied with personal protective equipment (PPE), only 12 (55%) emphasized its use and offered site orientation for new employees.  In the last part of the survey, respondents were requested to rate 25 factors affecting safety performance at the construction sites on a scale of 1 to 5, with 5 being the most important. The three most important factors of poor safety performance were the firm's top leaders, a lack of training, and the reckless operation of equipment. Conclusion: Changing attitudes of surrounding safety culture have the potential to significantly improve safety outcomes in the Saudi Arabian construction industry. Two Saudi Arabian corporations, Saudi Aramco and Saudi Chevron Petrochemical provide a positive model for increasing construction safety in the country, but there is a paucity of industry-level data. Further scholarly attention is strongly indicated.

Crocus Sativus L

Saffron (Crocus sativus L) has been widely used for many therapeutic purposes such as a pain reliever, inflammation cure due to the highly bioactive compounds, and antioxidant activities. The effect of boiling time (5, 10, and 15 min) was investigated on the bioactive compounds of saffron samples from different origins (Spain, Saudi Arabia, and Afghanistan). Depending on the origin of the saffron sample, the extraction time showed a different effect on their total polyphenol content (TPC). The highest TPC was noted in saffron from Spain boiled for 10 min (45.01 mg GAE/g DW), followed by the sample from Saudi Arabia (44.03 mg GAE/g DW) and Afghanistan (43.54 mg GAE/g DW) boiled for 15 min, respectively. The Spanish saffron extracted for 10 min significantly (p < 0.05) exhibited the highest total flavonoid content (TFC) (12.26 mg CE/g DW), while the Saudi saffron extracted for 5 min (6.06 mg CE/g DW) showed the lowest range among all the samples. There were no significant differences among the reducing power of Saudi Arabian saffron extracted for 10 min, and Spanish saffron extracted for 5 and 15 min, respectively. The reducing power of saffron samples echoed the results of the TPC and TFC. 1,2-DHB (dihydroxy benzene), chlorogenic acid, caffeic acid are increased upon the increase of boiling time in Saudi Arabian saffron samples. In a word, 10 min and 15 min boiling times achieved the best extraction for Spanish saffron followed by Saudi and Afghani saffron samples, respectively.

Abstract: This study explores married couples’ perception of the effects of using social media on marital relationships in Saudi Arabian society. The study discusses the growing use of social media, the common applications used, the reasons why married couples use social media, and the potential marital problems caused by the excessive use of social media. These issues are explored through the viewpoints of married couples living in Saudi Arabia. An online-based questionnaire was used to collect data, and the data sample comprised 1,226 married Saudi citizens; 55.7% male and 44.3% female. The data was analyzed using SPSS. The results show that the use of social media is common among married couples in Saudi Arabia, and that the majority use social media excessively. WhatsApp, Twitter, Instagram, and Snapchat are the most common applications used. The study also finds that married couples use social media for a number of different purposes, including communicating with family and friends, keeping up to date with celebrity and social media influencers’ news, as well as sharing photos and videos with others. Finally, spouses think that their partner’s excessive use of social media can cause marital problems, including the feelings of jealousy, the neglect of family responsibilities, the weakening of interpersonal communication, and the feelings of mistrust. Keywords: Social Media, Excessive Use of Social Media, and Marital Problems.

Key Factor

The role that language plays in the teaching and learning of mathematics is at the forefront of current literature in mathematics education. In this paper, I give particular attention to the manner in which teachers and students engage in the exploration of mathematical concepts and procedures with the goal of revealing how language impacts students’ learning. Through a series of examples of language commonly used in the mathematics classroom, I address specific issues pertaining to language used to describe mathematical processes, to read and interpret notation, and to define mathematical terms. Considering that communication is a key factor in the building of understanding, it is hoped that these examples will motivate teachers to examine and to adapt their own practices in order to cultivate productive and meaningful mathematical discourse in their classrooms.

Abstract Saudi Arabia has been seriously affected by COVID-19 across various administrative areas. Not only the prominent cities but also upcoming future cities and small townships were affected. This research aims at an analysis of COVID-19 data published by the Ministry of Health of Saudi Arabia to understand effects of broader administrative areas and neighborhoods and its interaction on spread of the epidemic. This research applies a generalized linear model (3 X 3) of administrative areas (major, middle sized and others) and neighborhoods (large, medium sized, and others) on COVID-19 infected cases classifying on a monthly basis from March to November, 2020. A total of 213 neighborhoods of various categories have been affected in the country with variousfrequencies and changes, based on local demographics. More than the broader administrative areas smaller neighborhoods receive significance and thus the interaction of variables in producing the number of cases: giving lessons for policies, programs and plans of development.

The Impact

The study concerns forecasting the number of soldiers in the Saudi Arabian army based on information obtained from the website: https://data.worldbank.org (The World Bank, 9.03.2020). The research began with a comparative analysis of the number of soldiers in the armies of Saudi Arabia and Russia. The idea for a comparative analysis of the number of armies of Saudi Arabia and the Russian Federation arises from Russian policy in the region of the Middle East countries, including the impact on world oil prices. The comparative analysis showed the similarities and differences in the dynamics of changes in the number of both armies dynamically. Subsequently, the primary time series data analysis on the number of Saudi Arabian troops was performed. The study selected methods for predicting raw data: Holt’s exponential smoothing and Klein’s model for the future. The next stage of the research was forecasting and the analysis and evaluation of the obtained forecasts. Klein’s model was the best forecasting model. The forecast of the number of soldiers in the Saudi Arabian army for 2020 is 251454, and for 2021, it has increased to 251006. The study ends with a summary and conclusions.
