The increasing prevalence of exploratory factor analysis (EFA) applications in scholarly literature reflects its popularity and the convenience of computer-assisted analysis. With advancements in computer hardware and software, the complexity and variations of EFA analysis have also grown. Despite the availability of sophisticated computer programming, the appropriate utilization of EFA necessitates users to make informed judgments. Additionally, users are responsible for searching and identifying suitable statistical software to accommodate their data and analysis requirements. This review aims to enhance understanding of the EFA technique and summarize the analysis options available for EFA in R packages. A total of 50 packages were examined in this study. Specifically, the review focuses on (1) diagnostic functions, (2) factor extraction, (3) factor retention, (4) factor rotation, and (5) complex data and technique features provided by these packages. The review summarizes the avail.....

This study delves into the integration of Project-Based Learning (PBL) and Computational Thinking (CT) to enhance 21st century learning. Through a Narrative Literature Review (NLR), pivotal strategies for effective implementation are identified. These include fostering collaborative pedagogy, employing visualization tools, embracing diverse inquiry approaches, providing scaffolding, integrating local materials, and incorporating framework elements. The findings highlight the significance of comprehensive frameworks and underscore areas for further research to enrich teaching practices. By adapting the PRISMA framework and reviewing relevant articles from 2017 to 2022, this study offers valuable insights for educators aiming to integrate PBL-CT successfully into their teaching methodologies. It emphasizes the need for constructivist and collaborative approaches to learning, along with the utilization of visualization tools to aid comprehension. Moreover, diverse inquiry approaches coupl.....

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Principal Editor. After a thorough investigation, the Editor has concluded that the review process for this article was compromised. The acceptance was based on information from at least two reviewer reports that were submitted from email accounts provided to the journal as suggested reviewers during the submission of the article. Although purportedly real reviewer accounts, the Editor has concluded that these were not of appropriate, independent reviewers. This manipulation of the peer-review process represents a clear violation of the fundamentals of peer review, our publishing policies, and publishing ethics standards. Apologies are offered to the reviewers whose identities were assumed and to the readers of the journal that this deception was not detected during the submission process...

Mobile apps for sign language are a fascinating area of research that merits a lot of attention. These apps are widely used due to their affordability and usability. Nevertheless, the quality of these apps needs to be evaluated if they are to have a significant influence. The outcomes of app quality assessment can also stimulate app development efforts and improvements to their functionality and accuracy. Therefore, to gain more in depth understanding, four academic databases (Science Direct, IEEE, Association for Computing Machinery, and Web of Science) were searched as part of a systematic literature review. The review highlighted that sign language apps require further development to support users in achieving the greatest possible usage and learning experience. We present a solution framework based on a quality assessment criterion for sign language mobile apps that could be adopted by academics and developers. Alternative identification, criteria, and development are the three pri.....

The analysis of the constituents of the leaves of Tradescantia spathacea yielded one new phenolic compound, named 3,6-di-tert-butyl-5-ethylphenol (1), along with four known compounds consisting of 1,1′-oxybis(2,4-di-tert-butylbenzene), β-sitosterol, β-sitosterone, and stigmasterol. All the structures were depicted using different spectroscopic methods such as NMR, IR, UV, and MS. Compounds 2–5 were reported for the first time to be isolated from T. spathacea leaves. The antioxidant activities of the compounds were tested using a DPPH free radical scavenging assay. Compound 1 showed potent antioxidant activities, while other compounds showed no significant antioxidant properties. © Springer Science+Business Media, LLC, part of Springer Nature 2024...

The agarwood tree is a type of tree that thrives in tropical rainforests and has been utilized and commercialized globally since long ago. Agarwood is widely used in producing perfumes, medicines, and cosmetics. This plant is widely found in Malaysia, Bangladesh, Indonesia, Myanmar, Thailand, Cambodia, Vietnam, Brunei, China, Sri Lanka, Nepal, Laos, Bhutan, India, the Philippines, Singapore, and Papua New Guinea. Malaysia's agarwood industry is also seen as having high potential and demand domestically and globally. Most of the studies conducted regarding agarwood have focused on foreign countries, while the agarwood industry in Malaysia is also growing positively and thriving. The present literature review also focused mostly on the aspect of agarwood farming. More research is still needed to clarify what factors contribute to the growth of the agarwood industry in Malaysia. Thus, understanding of these factors is worth exploring. A qualitative study through a multiple case study appr.....
