Social Media, Gender and Politics: Public Perception of Female Politicians through the Facebook
Authors: Ogunmusire Adebisi
Published: July 2024

Social Media is a dynamic form of communication platform that gives rapid feedback to messages posted/sent to targeted receivers. However, as much as there seems to be a fairly remarkable acceptance of females in politics, there is still an assumption that responses gotten on their social media platforms particularly are biased and unbalanced compared with that of their male counterpart. This work (a short field communication) evaluates the perception of messages received by or posted on the social media platforms of female politicians by the Nigerian citizens, based on responses and reactions to the social media updates and posts of these female politicians, using Facebook, as a case study. With the use of content analysis, the accounts of four selected female presidential candidates were purposively selected and analysed using Pew Institute data). The results revealed the suspected imbalance but noted an increase the citizens’ awareness of the effects of gender prejudice. It however avers that this could change with time because of the noticeable people’s sensitivity to effects of the imbalance. The study concludes that the dynamic nature of the social media goes a long way in influencing the sensitivity to the female gender.
On bayesian bonus-malus premium under linex loss function with applications
Authors: Imene Ouchen , Ahmed Sadoun , Farouk Metiri , Riad Remita Mohamed
Published: July 2024

The majority of bonus-malus systems (BMS) determine the premium for each policyholder solely based on their claim frequency. Adopting this method would be unjust. A driver who files a claim for small damage cannot be subjected to the same penalties as a driver responsible for a claim involving significant damage. To achieve a balance in the portfolio between good and bad drivers, a new portion of the premium is computed as a compromise. To do this, the claim severity is created and assessed to provide a fair premium. The consideration was determined by taking into account both the quantity and magnitude of the claims. This work assumes that the frequency of claims follows a Poisson-Akash distribution, but the severity of claims follows a newly proposed distribution known as the Inverse-Gamma Lindley distribution. The bonus-malus premiums were computed using the Bayesian approach for both the frequency and severity of claims. The premium is computed using the asymmetric Linex loss function for both the frequency and severity of claims in the bonus-malus system. Illustrative instances utilizing an actual dataset for the application of BMS are presented, showcasing the use of claim frequency alone and the combination of claim frequency and claim severity. The R software is employed for these demonstrations. We concluded this paper with a discussion comparing the premiums obtained in each case.

This study was carried out to screen the antifungal activity against Colletotrichum acutatum, Colletotrichum dematium, and Colletotrichum coccodes. Bacterial isolate GP-P8 from pepper soil was found to be effective against the tested pathogens with an average inhibition rate of 70.7% in in vitro dual culture assays. 16S rRNA gene sequencing analysis result showed that the effective bacterial isolate as Bacillus siamensis. Biochemical characterization of GP-P8 was also performed. According to the results, protease and cellulose, siderophore production, phosphate solubilization, starch hydrolysis, and indole-3-acetic acid production were shown by the GP-P8. Using specific primers, genes involved in the production of antibiotics, such as iturin, fengycin, difficidin, bacilysin, bacillibactin, surfactin, macrolactin, and bacillaene were also detected in B. siamensis GP-P8. Identification and analysis of volatile organic compounds through solid phase microextraction/gas chromatography-mass spectrometry (SPME/GC-MS) revealed that acetoin and 2,3-butanediol were produced by isolate GP-P8. In vivo tests showed that GP-P8 significantly reduced the anthracnose disease caused by C. acutatum, and enhanced the growth of pepper plant. Reverse transcription polymerase chain reaction analysis of pepper fruits revealed that GP-P8 treated pepper plants showed increased expression of immune genes such as CaPR1, CaPR4, CaNPR1, CaMAPK4, CaJA2, and CaERF53. These results strongly suggest that GP-P8 could be a promising biocontrol agent against pepper anthracnose disease and possibly a pepper plant growth-promoting agent.

The Application of Schema Theory in English Reading
Authors: Wang Xuanqi
Published: July 2024

English reading has always been an important part of English learning. However, many non-English major Chinese students do not pay attention to the cultivation of reading ability, but only passively learn with the goal of exams. At the same time, due to cultural differences, many difficulties arise in the process of English reading teaching. The development of schema theory provides language researchers with a good idea for studying reading behavior, and it also provides guidance for the teaching process of English reading for Chinese university students. Therefore, this paper uses a literature analysis method to study how schema theory works in English reading in different teaching methods, hoping to provide more teaching ideas for teachers. The study shows that currently, mind mapping and information technology teaching can effectively improve college students' English reading ability. In the teaching process, students use mind mapping to grasp different formal schemas and conduct top-down reading based on the mind maps they draw. At the same time, new media teaching and mobile learning also expand students' content schemas, promoting systematic learning of language knowledge for students.

Masculinity and Homosociality in Western Cinema: Taking Close (2022) as a Case Study
Authors: Liang Yaoya
Published: July 2024

Masculinity and homosociality in Western cinema undergo continuous evolution, transitioning from the construction of traditional ideals to contemporary, more diverse expressions, thereby presenting challenges and deconstructions. To contribute to the theorization of masculinity and homosociality in Western films, this study examines Lukas Dhont's Close to analyze how masculinity and homosociality are represented and negotiated to reproduce gender structures and heteronormative ideologies, and offer implications for future film presentations. Employing textual and formal analyses, along with relevant theories of masculinity and homosociality, this paper identifies different forms of masculinities embodied in hierarchical and horizontal homosociality. In doing so, this paper finds that homosociality provides space for some masculinities to assert and solidify their dominance while relegating others to subordinated or marginalized positions. The dynamic shifts in masculinity also correspondingly affect homosocial dynamics. Further exploration is warranted in presenting and constructing positive narratives surrounding non-hegemonic masculinity and horizontal homosociality, so that a diverse, anti-homophobic, and gender equality-supporting masculinity on screen may have the potential to achieve hegemony.
The Influence of Family Relationships on Adolescent Generalized Anxiety Disorder
Authors: Zhang Hongyi
Published: July 2024

This comprehensive review synthesizes a wide array of studies investigating the intricate relationship between family dynamics and adolescent Generalized Anxiety Disorder (GAD) using a literature review approach. Briefly analyzed and summarized the relationship between Generalized Anxiety Disorder and theories such as social learning theory, psychodynamic theory, and Bronfenbrenners ecological systems theory. The consensus across numerous investigations suggests a substantial impact of family relationships on the prevalence and manifestation of GAD among adolescents. Notably, findings consistently underscore the significance of parent-adolescent interactions and the quality of inter-parental relationships in shaping adolescent anxiety levels. However, most studies employ cross-sectional designs, limiting the establishment of conclusive long-term causal links. Also, prevalent self-report evaluations for anxiety disorders among adolescents pose limitations, lacking comprehensive, objective assessments that may affect research outcomes. Addressing these limitations in future studies is critical to comprehensively elucidate the nuanced relationship between adolescent GAD and family dynamics.

Authors: Fan Zhongsheng , Li Tianrui , Zhao Fanhua
Published: July 2024

In summary, this literature review has offered a comprehensive exploration of the origins and evolution of medieval religious orders. We've traced the pioneering efforts of figures such as the Desert Fathers and Irish monks, who embarked on radical ascetic experiments. From these early efforts, coenobitic rules emerged, providing structured frameworks for religious life. Notably, the Rule of Benedict played a pivotal role in balancing prayer, labor, study, and moderation. The advent of mendicant orders marked a revival of religious fervor through their commitment to poverty, mobility, and dynamic preaching. The rapid expansion of religious orders was made possible by elite patronage, facilitating their spread across Europe. These orders left indelible marks on education, politics, and culture, shaping medieval life. Religious figures assumed prominent roles as counselors to rulers, influential doctrinal shapers, and builders of educational institutions. By synthesizing scholarship, this review illuminates the multifaceted journey of medieval religious orders, from their humble beginnings to their profound impact on European civilization. It underscores their significance and lays the groundwork for further research on their enduring roles.

The emissions of greenhouse gases caused by the car industry are a substantial contributor to the problem that is the escalation of global warming into a serious crisis. In order to find a solution to this issue, it is essential to enhance the efficiency with which automobiles burn fuel. This goal can be accomplished by replacing heavier components of cars with those made of lighter materials while preserving the same level of safety. This paper discusses some new materials that can be used in vehicles instead of traditional steel, such as high-strength steel, aluminum alloys, magnesium alloys, and carbon fibre. It also determines the most suitable new lightweight materials to be applied to car bodies by comparing the mechanical properties of the various new materials, specifically the strength-to-density ratios of the various new materials. Based on the findings of the study, which compared the ratios of the materials' strengths to their densities, carbon fibre was shown to have superior qualities to those of other materials.
Application of artificial SEI layers for lithium metal battery anodes
Authors: Tan Jinqi
Published: July 2024

Unpredictable lithium dendrite growth on the metal anode and repeated destruction and creation of the solid electrolyte interphase (SEI) layer result in hidden risks and low Coulombic efficiencies (CEs). Researchers have found that designing a high-quality SEI layer can prevent the growth of dendrite. However, designing and forming a high-quality SEI layer is still a problem. Making trade-off between capacity reduction caused by the SEI layer and better cycle stability significantly limits the general performance of lithium metal batteries. In this research, characteristics of SEI layers and some significant advancements made in SEI formation are outlined. Some designs for the SEI layers on the lithium metal anodes include designing hybrid polymer SEI layers, producing synthetic SEI layers. By controlling the behaviours of Li ions throughout the stripping and depositing processes, the capacity and stability of Li metal anodes may be improved. Finally, some case studies of the applying of SEI in lithium metal battery systems are introduced.

Authors: Zhou Jiachen
Published: July 2024

With global temperatures on the rise, the trend of glacial melting is becoming increasingly evident. This study focuses on the northeastern region of Greenland as the research subject, utilizing remote sensing technology and geographic information technology to study glacial dynamics. Initially, the research processes Landsat 8 data using QGIS to classify the widespread snow and ice cover, facilitating the observation and analysis of its temporal variations. The study then narrows its focus to Terre de Lambert for further analysis. Subsequently, using satellite data from Sentinel-1 and employing SNAP, the research conducts an in-depth analysis of glacier flow speed in specific regions. Through intricate computational models and algorithms, precise glacier flow direction and speed maps are generated. By combining historical data, the study compares and analyzes the glacier flow speed between 2018 and from June 20th to July 14th, 2023. Results indicate that the glacier flow speed in 2023 during the same time frame was faster. Throughout the research process, limitations in current data acquisition and processing methods were identified. Thus, the paper suggests improvements to data acquisition and processing tools to enhance the efficiency of glacier flow speed studies. Theres a fervent hope for the emergence of more convenient, streamlined, and customizable temporal dimension tools for glacier flow speed data in the future. The research findings aim to draw global citizens attention to the issue of glacial melting and inspire collective actions to protect our planet.
