Item Restricted The Impact of Oil Price Changes on Stock Markets and Firms’ Financial Performance: Evidence from Saudi Arabia and the UAE(Saudi Digital Library, 2025) Alharbi, Mohammad; Azevedo, AlcinoThis study looks at how oil price changes affect stock markets in the Gulf and the financial performance of Saudi firms. Oil still plays a major role in these economies, and shifts in global prices often appear quickly in local markets. The research focuses on the Tadawul All Share Index (TASI) in Saudi Arabia, the Abu Dhabi Securities Exchange (ADX) in the UAE, and company outcomes measured through Return on Assets (ROA). The aim is to see how far oil price swings matter for daily market returns and firm-level results, and whether the impact is stronger in oil-related industries than in more diversified ones. The dataset covers 2009–2024. It includes daily returns for TASI and ADX, which are matched against Brent oil prices, while firm-level regressions test the effect on profitability. The analysis applies Ordinary Least Squares (OLS) and panel regressions with both fixed and random effects. Outliers are reduced through winsorisation, and industry dummies are used to capture sector differences. The findings show that TASI is more responsive to oil price changes than ADX. At the company level, firms linked closely to oil are more sensitive, while diversified firms are less affected. GDP growth has only a smaller role. Overall, the evidence highlights the ongoing reliance of Gulf markets on oil and underlines the importance of economic diversification.17 0Item Restricted Investigating the importance of technological advancements in logistics and supply chain management and how they help meet global sustainability Goals(Logistics and Supply Chain Management, 2024) Alharbi, Mohammad; Hwang, Ki-SoonLogistics management and Supply chain management are the terms associated with supply chain management, which involves activities such as planning, sourcing, generating, and delivering goods and services. Logistics, on the other hand, involves emphasising the track of processes so that the right products are at the right place at the right time. Along with these processes, technological advancements play significant roles in terms of productivity, efficiency and attainment of sustainable goals. In this context, this research study aims to explore the investigation of technological advancements such as artificial intelligence (AI), blockchain technology (BCT), internet of things (IoT), automation and robotics in supply chain and logistics along with meeting the sustainability goals. Therefore, this research will fill the gap in the prevailing literature on technological advancements and carbon reduction by including a specific study of the automotive manufacturing sectors. In terms of methodology, a questionnaire survey was conducted through structured closed-ended questions including the sixty-four participants as stakeholders of the supply chains and logistics. The key findings or results reveal the information or understanding that, technological advancements optimise inventory management and also help in reducing waste for sectors like manufacturing in the Automotive industries. Along with this, technical development improves the productivity of supply chain management as well as logistics by accomplishing global sustainability objectives and reducing carbon emissions in the manufacturing sector. In this research study, the different obstacles to adopting sustainable logistics technology are also explored by promoting the application of renewable energy and green logistics in different sectors. One of the significant limitations of this research study is that it does not involve all aspects of green technology and green technologies can be a good option for future research study. The conclusion as well as recommendations drawn in the present studies, are expected to offer a significant insight for supply chain management and logistics to get a competitive advantage in terms of attaining sustainable execution with the usage of logical advancement.40 0Item Restricted The treatment of fraction concepts in primary mathematics textbooks in Saudi Arabia and Japan(2023-11-23) Alharbi, Mohammad; Tasara, InnocentAs a result of identifying the potential reasons between Saudi students' achievement and their Japanese peers (According to TIMSS results), this research sought to identify the causes by examining primary mathematics textbooks in the two countries on fractions. The content analysis findings indicate that the Saudi textbook introduced fractions in the first grade, while the Japanese textbook introduced them in the second grade. In addition, both textbooks introduced fractions through area models. However, the Saudi textbook focused on area models to develop an understanding of fractions as numbers, while the Japanese textbook focused on the length models, specifically the number line. Another result is that the Saudi textbook recognised fractions by identifying the already partitioned parts, while the Japanese textbook relied on partitioning the whole into parts. In addition, the Japanese textbook emphasised that fractions are composed of unit fractions. Moreover, the Japanese textbook emphasised developing students' understanding of proper fractions, improper fractions, and mixed numbers, while the Saudi textbook emphasised developing students' understanding of proper fractions.56 0
