Linking components of social media usage to psychological distress: integrating the situational theory of problem-solving and social capital theory
No full textDespite extensive research on psychological distress, studies that examine how social media usage impacts psychological distress are notably missing. This study employs the lenses of the situational theory of problem-solving and social capital theory to examine the relationship between social media usage and psychological distress. Our hypotheses propose that social media activities play a mediating role in the relationship between social media usage and psychological distress, while media skepticism and interpersonal injustice act as moderating factors. A structured questionnaire was developed and distributed to social media users in five major Chinese cities: Shenzhen, Guangzhou, Dongguan, Zhuhai, and Shantou. Non-probability convenience sampling and a two-wave research design were employed to collect data from 866 social media users. The results indicated a positive association between social media usage and psychological distress. Notably, social media activities were a positively significant mediator of this relationship. However, the moderating effect of media skepticism was non-significant, while interpersonal injustice reduces the impact of social media usage on psychological distress. The relationship between constraint recognition and psychological distress was not significant. These findings lead to practical insights for efficiently controlling social media participation and online behaviors, while also considering how interpersonal unfairness and other factors influence users' emotional distress levels
A comprehensive review on the processing, composition, and safety of fermented rice products and advanced methods for improving its quality
No full textIn many countries, rice, which contains numerous nutrients, is a primary staple food consumed by more than half of the world's population. Fermenting rice efficiently enhances its nutrient bioavailability and promotes better health benefits. Many cultures favor fermented rice for both its health advantages and its appealing sensory qualities. It is rich in microflora and functions as a probiotic, thus improving immunity and digestive health. This review includes information from all accessible library databases (i.e., Google Scholar, Web of Science, Scopus, ScienceDirect, and PubMed Central), including books and online databases from 1994 to 2024. Various aspects related to fermented rice including the fermentation process, microbial and sensory properties, physicochemical and biochemical changes in fermented rice products, safety risks, concern about fermented rice products, halal issues, safety regulations, quantitative risk assessment, Hazard Analysis Critical Control Point (HACCP) system, basic good manufacturing and hygiene practices, and metabolomics aspects are discussed. Additionally, this review can benefit the researchers as well as food sectors involved in the commercialization of fermented rice by providing fundamental insights into fermentation processes and guidance for generating high-quality products without compromising customer safety and health

Full text linkEnhancing physical education through blended learning: Impact on student self-efficacy and performance
Full text linkThis study evaluates how blended learning influences student outcomes in physical education through self-efficacy and performance assessments. A mixed-methods approach was used for data collection, combining quantitative pre-and post-intervention assessments of student performance (measuring changes in fitness, skills, and academic outcomes) with qualitative interviews to gather insights on student perceptions of self-efficacy and blended learning experiences. A control group was established to compare the effects of traditional physical education methods with blended learning. Ten students were randomly selected from the student population to participate in this study. Statistical techniques were employed to compare and correlate pre-and post-intervention results with qualitative data to gain a comprehensive understanding of how outcomes are influenced by blended learning. This study aims to add empirical knowledge on incorporating blended learning into physical education and its practical applications. It offers recommendations for educators and policymakers on effectively using blended learning strategies to optimize student self-efficacy in physical education settings
A systematic review of machine learning and deep learning techniques for anomaly detection in data mining
No full textThe growing use of the internet has increased the threat of cyberattacks. Anomaly detection systems are vital for protecting networks by spotting irregular activities. Various studies investigated anomaly detection techniques without a systematic approach. So far, the existing reviews mainly concerned time series and data streaming methods almost neglected the growing interest in graph-based data mining techniques which are vital in social networks, finance, and IoT domains. Following PRISMA guidelines, this systematic review examines anomaly detection methods applied to time series, data streaming, and graph-based data from 2018 to 2023. A total of 34 papers were selected from four key databases ScienceDirect, Scopus, Web of Science, and IEEE. In addition, this review addressed several issues with existing techniques including low scalability, explainability, and interpretability for real-time anomaly detection systems. In modern applications where data structures are complex, and processing requirements are high these traditional techniques are insufficient for real-time data processing. Finally, our study demanded more advanced, complex methods to address these evolving challenges

Analyzing mood structures in the Quranic stories of Nuh: a comparative study of Quranic translations
Full text linkTo properly translate rhetorical questions, the paper addresses how to preserve and analyze thematic structures in translations of religious texts. It mainly concentrates on how translators understand and communicate the interpersonal mood structures found in the Quranic Nuh stories in the Quranic translations by Abdullah Yusuf Ali and by Muhammad Taqi-ud-Din Al-Hilali and Muhammad Muhsin Khan. Nuh's stories were chosen mainly because they provide a rich tapestry of divine pronouncements, pleas, and rhetorical inquiries and highlight how clear mood rules conversations, aiming at explaining the impact of translation choices on mood distribution and potential interpretive nuances. Employing the Systemic Functional Linguistics (SFL) framework, the study analyzes the distribution of declarative, imperative, and interrogative moods within the Nuh stories across both translations. The analysis revealed a consistent dominance of the declarative mood across the two translations, reflecting the narrative's primary focus on conveying information and pronouncements. However, significant variations emerge in the usage of imperative and interrogative moods. The study identifies translator-specific tendencies, highlighting how confident choices amplify or subdue the urgency of commands or the intensity of rhetorical questions. Furthermore, the findings show that linguistic variations exist across languages regarding how declarative is constructed. Findings also articulated the diverse subtypes that help realize emerging declarations within different translation approaches. Moreover, Nuh's stories show high imperative usage by reflecting the guidance-oriented themes. Conversely, the blend of declarative, imperatives, and interrogatives at the particular stage of Nuh's spreading Allah’s message hints at a dynamic interplay of information, instruction, and rhetorical questioning

Adaptive reactive power control for voltage rise mitigation on distribution network with high photovoltaic penetration
No full textThis research addresses the challenge of voltage rise on low voltage distribution networks with high photovoltaic penetration. The proliferation of distributed generators, particularly small-scale PV systems, has raised concerns about voltage stability and power quality in these networks. Existing reactive power control techniques, such as fixed power factor and voltage-based methods (Q(V)), have limitations in effectively mitigating voltage rise while considering load variations and network sensitivity. To overcome these limitations, an adaptive reactive power control technique is proposed in this research. The technique combines both PV active power injection and network voltage considerations in real-time to dynamically adjust reactive power output. Unlike traditional methods, which directly link reactive power reference to PV active power or voltage, the adaptive technique calculates the change in reactive power reference (ΔQ) based on both factors. This dynamic approach enables more responsive and accurate voltage regulation. The effectiveness of the adaptive technique is demonstrated through MATLAB simulations on a representative low voltage distribution network. The results show that the adaptive technique outperforms existing methods, providing better voltage regulation and reduced losses. The technique's adaptability to different scenarios and variations is also highlighted. However, it is noted that the adaptive technique may have a slightly slower response time compared to existing methods due to its dynamic nature
