Size dependent compositional variations for the ordered L12-structure gamma prime (γ′) precipitates in the commercial Ni-based superalloy RR1000 have been investigated using scanning transmission electron microscope (STEM) imaging combined with energy-dispersive X-ray (EDX) spectroscopy. To address the problem of quantitative compositional determination for nanoscale particles within a metal matrix we have applied a novel electrochemical method to extract individual precipitates. The use of a high-efficiency EDX detector enabled compositional measurements to be obtained for particles with diameters as small as 20 nm with acquisition times of the order of a few minutes. We have studied compositional variations across the different size families of γ′ precipitates within a microstructure generated by slow cooling. Our results demonstrate the importance of kinetic factors for determining the precipitates compositions. In particular, we provide new evidence for the role of aluminium antisite atoms on the low-temperature growth kinetics of fine scale γ′ precipitates. Our findings provide valuable structural data towards improving the accuracy of predicting the microstructural evolution in Ni-based superalloys.

The emissions of car brakes are a type of emission which is yet slightly evoked but which might be of major public concern soon. Few studies on the subject are available today, which moreover lacks methodological consensus. An international comparison of the results for example from brake benches is still impossible. The present scientific communication aims to show the requirements needed to design an experiment to measure brake emission; and more specifically using a pin-on-disc system.; Les particules émises par le freinage automobile constituent un type d'émission peu évoqué à ce jour bien qu’il risque d’émerger prochainement. Peu d’études traitant du sujet sont disponibles, un sujet qui par ailleurs ne fait l’objet d’aucun consensus méthodologique permettant une comparaison internationale des résultats obtenus par exemple des bancs de freinage. La présente communication vise donc à exposer les différents critères à définir lors de la mise en place d’un système de mesure des émissions dues au freinage ; et notamment sur un système pion-disque.

Social Sciences - Abstract
Based on the job demands-resources model, the mechanism and boundary conditions of leader-member exchange social comparison on employee innovative behaviors were tested with self-efficacy and role load as mediating variables and error management climate as moderating variables. Based on the empirical analysis of 452 questionnaire data collected in two stages, it is found that self-efficacy and role load play a partial mediating role in the relationship between leader-member exchange social comparison and employee innovative behavior. Error management climate positively moderates the relationship between leader-member exchange social comparison and self-efficacy, and positively moderates the mediating role of self-efficacy in the relationship between leader-member exchange social comparison and employee innovative behavior. Error management climate negatively moderates the relationship between leader-member exchange social comparison and role load, and negatively moderates the mediating role of role load in the relationship between leader-member exchange social comparison and employee innovative behavior.

Environmental sciences ,GE1-350 - Abstract
China’s rapid economic development is accompanied by severe environmental problems. Chinese government has taken some measures to improve environmental conditions and protect diverse ecosystems, but these problems still exist. Science and technology are the main measures to improve the ecological environment, but the impact of ecological literature on the environment cannot be underestimated. As a medium for expressing opinions and emotions, ecological literature has become an important way to reflect the social environment, which has attracted widespread attention from ecological and environmental scholars and social people. Therefore, this article aims to explore the power of ecological narratives in ecological literary works and how this narrative affects people’s awareness and social behavior of ecological and environmental. Taking China as an example, this article analyzes the ecological narrative elements, the influence of readers, the influence of social public opinion, and the influence of the Chinese government’s environmental policies in many ecological literary works in China. Finally, it was discovered that ecological literature, as a literary form, shows the power to transcend time and space, profoundly affects the environmental awareness of contemporary society, and lays a solid foundation for the improvement of the ecological environment.

Environmental sciences ,GE1-350 - Abstract
In this paper, the influencing factors of environmental population capacity are categorized into three types: strict constraints, elastic constraints and non-constraints, and the systematic relationship among the three types of factors is explored, from single-factor environmental population capacity model to multifactor environmental population capacity model, and finally to obtain the regional environmental population capacity model. In this paper, we choose to take Hainan Island in China and the island of Ireland, which have similar natural conditions (area, population, etc.), as examples to measure the environmental population capacity based on the island. From the perspective of environmental capacity, this paper explores how to make the global distribution of population settlements more in line with the distribution of environment and resources, and then puts forward more effective and reliable suggestions for the coordinated development of population and economic and social resources and environment.

Microbiology ,QR1-502 ,Physiology ,QP1-981 ,Zoology ,QL1-991 - Abstract
Glutamic acid is widely recognized as safe and has various applications in the medical and food industries. This study demonstrated its significant inhibition of tyrosinase, acting as a mixed-type inhibitor according to enzymatic kinetic analysis. Fluorescence spectroscopy analysis and investigation of tyrosinase activity under different pH confirmed that glutamic acid induced changes in the protein structure of tyrosinase, leading to its reduced activity through acidification and binding effects. Additionally, glutamic acid was found to inhibit L-DOPA auto-oxidation, thereby preventing further formation of dopachrome. The IC50 values for glutamic acid inhibiting tyrosinase activity and L-DOPA auto-oxidation were detected to be 4.69 mM and 0.72 mM, respectively. Glutamic acid had a better inhibitory effect on L-DOPA autooxidation than tyrosinase activity. The L-DOPA auto-oxidation process can also lead to the formation of melanin, and its inhibition by glutamic acid further supported its potential in controlling melanin synthesis. Moreover, glutamic acid demonstrated a dose-dependent decrease in melanin production in B16 cells while maintaining cell viability. Western blot analysis revealed decreased protein expression of TYR and TRP-1, both of which are involved in melanin production, with increasing concentrations of glutamic acid. Molecular docking analysis suggested a potential mechanism involving the disruption of copper binding sites on tyrosinase. These findings underscore the potential of glutamic acid as a promising agent for controlling melanin production and associated disorders.

Social Sciences - Abstract
As a traditional Japanese literary concept, the concept of “mono no aware” gradually forms an aesthetic consciousness deeply rooted in Japanese culture through the interpretation and enrichment of local literature, poetry, film and television. This aesthetic consciousness is a series of melancholic and melancholic emotions that the aesthetic subject experiences towards the aesthetic object, as well as a pessimistic feeling towards the fleeting moments of life and the impermanence of time. It resonates with emotions, and this emotional expression is introverted and implicit. Even though there are waves in the heart, the surface is only a frown, revealing a faint emotion. This article is based on the analysis of Makoto Shinkai's animated films, and explores the common aesthetic ideas and realistic meaning. the conclusion is as follows: Makoto Shinkai combines traditional aesthetic ideas with modern computer technology to form a more delicate and resonant new unconscious aesthetic. This aesthetic is presented layer by layer through a series of life oriented themed animated films such as “regret”, “love”, and “distance”. It can better touch people's inner softness, comprehend the true essence of life, and awaken people's hope and motivation for life.

Environmental sciences ,GE1-350 - Abstract
In this paper, based on the panel data of China's carbon dioxide emissions, economic and energy development from 2000 to 2022, per capita GDP and carbon emissions are used as analysis indicators.The environmental Kuznets theory serves as the basis for an analysis of the correlation between economic progress and carbon dioxide emissions.The findings indicate that China's GDP and carbon emissions increased between 2000 and 2022. From 7,912 yuan in 2000 to 85,698 yuan in 2022, the per capita GDP grew by over ten times. Although per capita carbon emissions generally increased, they declined between 2014 and 2017, It might be connected to the nation's strong initiatives to support green development and the restructuring of the energy structure.For specific explanations,please refer to 4.1 Temporal evolution characteristics of carbon emissions and GDP. China is still in a transitional phase when it comes to environmental preservation and economic development, as seen by the N-shaped curve connecting the country's carbon dioxide emissions and economic growth rate. Based on this theory, the Tapio decoupling theory provides an understanding of the decoupling relationship between carbon emissions and economic growth based on carbon accounting. The irrational use of coal, oil, natural gas and other fossil fuels as the main energy has caused a series of environmental problems and seriously restricted economic development. Therefore, Stronger innovation and promotion of low-carbon and green technologies are required, as is the reduction of carbon emissions from the industrial structure and method of economic progress.

Currently, gaseous molecular contaminants (acetic acid) is one of the main factors that cause defects in semiconductors and wafers, reduce product yields in high-tech process plants. Propylene Glycol Monomethyl Ethyl Ether Acetate (PGMEA) is a versatile solvent with many applications. Solvents used in the solder mask process in the manufacture of printed circuit boards (PCBs). The diluent in photoresist and edge bead removers used in semiconductor and wafer fabrication is PGMEA, which forms acetate contaminants through an acid-catalyzed hydrolysis reaction. The concentration standard of acetic acid pollutants in clean rooms is 1ppb.In order to protect the expensive optical components, the acetic acid generated by PGMEA needs to be controlled.For this purpose, the activated carbon filter in the intake filter prevents acetic acid from contaminating the components and corroding the material. In this study, we used the commercially available activated carbon fabricated filter to adsorption of acetic acid. The effect of adsorption under different face velocity (0.03/0.06/0.09 m/s) and initial acetic acid concentrations (4/6/8/10 ppm) were measured according to the principle of ASHRAE 145.1standard. The experimental data are also evaluated for adsorption performance, adsorption capacity, kinetic model of acetic acid adsorption process, and isothermal model of acetic acid adsorption process.The results of the acetic acid adsorption experiment show that MM3000 activated carbon has the highest adsorption capacity and the longest adsorption saturation time than KPL activated carbon. The higher the inlet acetic acid concentration at a fixed wind speed, the shorter the saturation time and the higher the adsorption capacity; the faster the wind speed at a fixed acetic acid concentration, the shorter the saturation time and the higher the adsorption capacity.The Langmuir (R2) of the MM3000 sample is higher than the Freundlich’s coefficient of determination (R2), which indicates that the adsorption phenomenon of the MM3000 sample is more suitable to be described by the Langmuir isothermal adsorption mode, which is the adsorption of a single molecular layer on a homogeneous surface. The Freundlich R2 of the KPL sample is higher than the Langmuir’s coefficient of determination (R2), which means that the adsorption phenomenon of this KPL sample is more suitable to be described by the Freundlich isothermal adsorption mode, and it is a case of adsorption of multiple layers on an inhomogeneous surface. The adsorption of MM3000 activated carbon and KPL activated carbon is more suitable to be described by the proposed second-order adsorption kinetic model, which is a phenomenon of chemisorption.

The United Nations points out that extreme climate events are frequent and widespread in the 21st century and have become a global security issue. Artificial intelligence and machine learning have attracted much attention in environmental applications. This study aims at applying machine learning (ML) to rice disaster prediction, and uses SPSS to analyze environmental impact factors. After model training and evaluation, four models are provided, among which short-term prediction results show high accuracy on a single event, which are suitable for water damage, cold damage, and plant diseases and insect pests respectively. In terms of longterm prediction, using future meteorological prediction values to predict potential rice losses is better, especially within a specific time period. Ultimately, relevant units such as the Council of Agriculture or the AgriFood and Food Administration can choose a suitable model based on different purposes (short-term or long-term forecasting).

At present, the alkylbenzene insulation oil for submarine cables of 220kV and above in China relies on imports, which poses high maintenance costs and supply interruption risks. Nano modified insulating oil has excellent electrical properties and broad application prospects in power systems. Therefore, nano SiO2 modified insulating oil was prepared, and the effects of APTES modified and unmodified nano SiO2 on the viscosity, breakdown voltage, and dielectric loss factor of the insulating oil were compared. The results showed that the viscosity of alkylbenzene insulating oil did not change significantly after the addition of nanoparticles, which met the operating standards for submarine cable oil; The breakdown voltage of the modified nano insulating oil has significantly increased, with a breakdown voltage of 0.12g/L being the highest. The breakdown voltage of the unmodified nano insulating oil has significantly decreased. The dielectric loss factors of modified and unmodified nano insulating oils do not vary significantly. This article provides theoretical and practical references for the domestic substitution research of submarine cable insulation oil.

Oil-filled submarine cables have come to dominate the reliable delivery of electrical power today, but oil leakage still remain a challenge. This work focuses on the exploring of spill behavior of dodecylbenzene (DDB) after leakage and the detection of DDB. Static and dynamic spill model were established to study the spreading and migration behavior of underwater DDB. In still water, the spilled oil droplets can quickly reach the uniform floating speed of 0.13 m s-1 with no significant change under different oil spill rates. DDB can be dispersed as small droplets in seawater, which the diameter of DDB droplets increased from 60 nm to 200 nm with the increase of the concentration from 10 ppm to 1000 ppm. This study suggests a research basis for finding the leakage point of submarine cables, and explores the way for detection of DDB.

Environmental sciences ,GE1-350 - Abstract
The nitrify-based technology has already been regarded as an economical and efficient strategy to remove nitrogen. This study investigated different oxytetracycline (OTC) concentrations inhibited the nitrifying process of an aerobic wastewater treatment system in short-term shocks. The stability of ammonia nitrogen removal had declined trend and demonstrated nitrite accumulation when the concentration of oxytetracycline was 0,1,2,5,10,20mg/L, respectively. And the ammonia oxidation reaction time decreased from 240 min to 120 min. Mixed liquid suspended solids (MLSS) decreased by 50.69%, 48.53%, 74.28%, 65.03%, and 72.97%, respectively. Compared to control OTC (0 mg/L), S-PN decreased from 2.256 mg·gVSS-1 to 0.016 mg·gVSS-1, 0.294 mg·gVSS-1, 0.094 mg·gVSS-1, 0.649 mg·gVSS-1, 0.349 mg·gVSS-1. Total EPS decreased from 7.795 mg·gVSS-1 by 17.00%, 32.91%, 45.09%, 43.04%, and 29.57%, respectively. High-throughput sequencing analyses showed that Proteobacteria and Bacteroidetes were the most phylum. The relative abundance of Nitrospira decreased as the OTC concentration increased, while that of Comamonas increased.

Environmental sciences ,GE1-350 - Abstract
At the beginning of the 21st century, due to the re-proposal of the United States space exploration program, heat pipe reactors once again received widespread attention from researchers. With their long lifespan, high energy density, and inherent safety features, they exhibit promising prospects for application in space nuclear reactors, land-based mobile nuclear power sources, and deep-sea unmanned equipment exploration. Consequently, they represent an ideal novel energy source for unmanned underwater vehicles (UUVs). This article selected the SUBOFF submarine model as a basis to calculate UUVs’ navigation resistance at various speeds using the 1+k method. By comparing the converted UUVs navigation power demand with that of traditional batteries and heat pipe stacks’ output power, it was concluded that heat pipe reactors offer superior power supply and endurance capabilities. Subsequently, based on the structural characteristics of the heat pipe stack, this study summarized battery advantages and characteristics while also addressing construction and development aspects of heat pipe stack energy systems. Furthermore, the key technologies that need to be overcome in the application of heat pipe stacks in UUVs are introduced. Through the formula of heat transfer limit of heat pipe, the factors that limit the heat transfer performance of heat pipe are analyzed, and the positive correlation among the number of heat pipe, heat transfer limit and heat transfer power was obtained. Finally, the challenges faced by the future application of heat pipe stacks in UUVs were pointed out.

The self-construction of the sustainable development guarantee system for international cooperation and exchange in vocational colleges is an activity that draws on the advanced experience of domestic and foreign vocational colleges, combines reality with the school situation, and localizes and innovates international experience. Each country has its own national conditions, and each vocational college has its own specific situation. International experience cannot be blindly copied, and all universities cannot operate in a homogeneous manner according to a single model, let alone turn internationalization into Westernization. The prerequisite for maintaining vitality through internationalization is localization. Vocational colleges selectively absorb good concepts, ideas, and practices from foreign education, integrate their own characteristics and culture, extract methods and models suitable for national conditions and school conditions, and transform and innovate them. They compile normative institutional documents for implementation, thereby promoting the integration of internationalization and localization.

Environmental sciences ,GE1-350 - Abstract
In order to improve the efficiency of traffic flow and reduce the delay of arterial intersections, a coordinated signal control method based on numerical solution is proposed. Firstly, considering the factors such as the shortest green time and saturation of a single intersection, the intersection delay model is established. Secondly, the traffic capacity of the trunk line is improved by optimizing the public cycle and the green ratio of each intersection. Finally, an optimization model with minimum delay as the optimization objective is constructed, and the signal coordination of arterial intersections is realized by taking Yancheng City as an example. The results show that the coordinated control model of adjacent intersections based on the numerical method can reduce the average vehicle delay of two-way vehicles, achieve the purpose of green wave coordinated control of road sections, and improve the road traffic capacity.

Environmental sciences ,GE1-350 - Abstract
Facing rapid growth in air cargo demand within the global supply chain and limitations of traditional storage location allocation methods, this study proposes an intelligent optimization strategy for storage location allocation. The strategy considers key factors like flight schedules, cargo collection and delivery data, cargo terminal topology, and in-and-out paths. It intelligently allocates each cargo batch to the most suitable location, assigning more flights' cargo to locations near the exit, thereby reducing cargo handling distance and offloading time, and enhancing operational efficiency and cargo handling capacity in the air freight sector. The algorithm, based on the latest optimization theories and techniques, seeks optimal solutions under various constraints. The model and algorithm’s effectiveness is validated through simulation experiments using actual flight data. The results indicate that, compared to traditional strategies, the optimized strategy reduces response time by 62%.

Music, often heralded as the universal language, wields an unparalleled power to bridge gaps, transcend borders, and knit together the mosaic of global cultures. It manifests in a kaleidoscope of forms, each echoing the unique cultural heartbeat of its origin, painting a rich tapestry of human society with its melodious strokes. This paper sets out to explore the enthralling diversity of musical traditions that span the globe, delving into the complex relationship between music, culture, and the fabric of society. From the ethe-real strains of classical Indian ragas, steeped in centuries of spiritual tradition and philosophical depth, to the pulsating beats of African drumming, acting as the vibrant pulse of community life and social gatherings, we uncover the deep-seated influence of music. Music serves not only as a reflection of cultural identity and societal values but also as a pivotal force in shaping them. It mirrors the historical, social, and spiritual narratives of its people, while also acting as a catalyst for social cohesion and identity formation. Through communal singing, dancing, and the shared experience of music-making, it forges strong bonds among individuals, knitting them into a cohesive social fabric. The exploration of music’s varied traditions across the world reveals its role as a cultural lodestar, guiding societies through the currents of time and change. By tracing the intricate interplay of music with cultural and societal dynamics, we gain profound insights into its role as a potent force in shaping the essence of our collective human experience. Music, in its myriad forms, not only entertains but also educates, inspires, and unites, highlighting its indispensable place in the mosaic of human culture. Through this journey across the musical landscapes of the world, we appreciate the universal language of music in all its diversity, understanding its capacity to embody the shared emotions, experiences, and aspirations of humanity.

Environmental sciences ,GE1-350 - Abstract
Vertical greening is one of the effective measures to improve the microclimate and air quality of high-density urban street canyons, and its impact on the thermal environment is closely related to the street canyon morphology. In this paper, based on the characteristics of high-density urban street canyons in the context of Shenzhen City, 12 sets of cases (two orientations, two aspect ratios, and three height-to-width ratios) were simulated and designed using ENVI-met software to study the effects of vertical greening on the thermal environment of buildings under different street canyon morphologies, and to summarize the impact of vertical greening on the microclimate of different street canyons. The results of the study show that the orientation of the street canyon is the most influential factor in the thermal efficiency of vertical greening under the street canyon geometry with the same amount of greening and that the vertical greening effect of east-west oriented street canyons is generally better than that of north-south oriented street canyons in terms of cooling, humidification, and improvement of thermal comfort at the walking level.

Environmental sciences ,GE1-350 - Abstract
A micro-organic Rankine cycle (ORC) system utilizing R134a as the working fluid and a scroll expander has been developed. In this study, the effects of superheat degree on system performance were investigated by varying the evaporation temperature and refrigerant mass flow rate. The heat sources used in the ORC system were three different temperatures: 85℃, 95℃, and 105℃. The results indicate that the refrigerant mass flow rate increases with the rise in evaporation pressure, while superheat degree decreases. Moreover, higher superheat degrees led to a reduction in the system power generation. The trend of net efficiency demonstrates that when superheat degree increases, the net efficiency first rises to a peak before declining. At heat source temperatures of 85℃, 95℃, and 105℃, the peak net efficiencies are 4.86%, 5.56%, and 5.87%, respectively, with corresponding superheat degrees of 25.72K, 36.16K, and 38.15K.

Social Sciences - Abstract
With the growing digital economy and the impact of the Covid-19 pandemic in the past two years, video games have become the mainstream entertainment for general public. Some game companies have chosen acquisitions over the past few years to expand their market share and enhance their competitiveness, but acquisitions come with many risks. This paper analyses the strategic intentions and risks of Microsoft’s acquisition of Activision Blizzard, and puts forward forward-looking suggestions based on the concept of metacomes. It is believed that the meta-universe is the core of the future of the game industry, and Microsoft’s acquisition of Activision Blizzard helps it occupy a strategic commanding height in the meta-universe field, but it needs to pay attention to antitrust risks and cultural integration problems. To this end, it can be suggested that Microsoft should strengthen cultural management and regulatory responsibility, open platform cooperation, and strengthen meta-cosmic technology research and innovation.

Social Sciences - Abstract
The Russo-Ukraine war has drawn attention worldwide. Previous studies have revealed how the conflict affected global patterns and international interactions. This article refined the scope of the study by focusing on the agenda-setting and attribute agenda-setting that media in mainland China and Taiwan Province of China set when reporting the Russo-Ukraine war. A total of 471 of the People’s Daily and the Liberty Times’ news were examined by the LDA model to categorize their agendas and key words of the attribute agenda-setting. The study found that both parties set four agendas: diagnose causes, economic consequences, international relationship and remedy. Mainland China additionally added nationalization agenda. The huge differences in attribute agenda-setting between the two sides were a reflection of the divergent political objectives of the two parties in mainland China and Taiwan province. The results suggested that the Russo-Ukrainian war was revealed by a multiparty convergence of media and government agendas, and neither medium paid heed to the public agenda in their reportage.

Social Sciences - Abstract
With the wide application of advanced technologies including AI which with high precision and automation level, financial technology has shown a progressive trend, and quantitative trading strategies have bright prospect. Based on China’s A-share market, this study constructs a quantitative strategy for stock selection by combining the industry rotation effect with a multi-factor model considering investor sentiment. Firstly, the strategy screens the target industries according to the rotation factor calculated by PER, and then determine the stocks by the multi-factor model formed by the factors after effective test. In this study, the effectiveness of the strategy is verified through six constructed back-test portfolios from both sides. According to the analysis, the return of the strategy considering the rotation effect and investor sentiment is higher than the market. The comparison of the impact of the rotation factor and the emotional factor shows that the change of macro and middle environment has a greater impact on stock prices than the micro level. Up to now, there are few stock selection strategies considering both rotation effect and investor sentiment. These results attempt to supplement this aspect and enrich the field of asset pricing.

International audience; Les breathers sont communément utilisés en physique pour examiner des problèmes d'ondes modulées et instables. Pour le cas des ondes de surface, c'est un modèle intéressant pour expliquer un des mécanisme d'apparition des vagues scélérates. Les breathers sont solutions de l'équation non linéaire de Schrödinger. Les solutions de cette équation peuvent être stables ou instables en fonction du paramètre kh lié à la profondeur et au nombre d'onde. Si kh est inférieur à un seuil égal à 1.363, la solution est stable. Donc le domaine d'application des breathers est de ce fait limité aux grandes profondeurs. Cependant, on peut se demander qu'elle est l'évolution de ces trains de vagues quand ils rentrent dans la zone côtière. Pour répondre à cette question, une série d'expériences a été réalisée au Tainan Hydraulics Laboratory (THL) à Taiwan. Summary Breathers are commonly used in physics to deal with modulated and instable wave train problems. For the free surface wave, it is an interesting model to explain one mechanism of the appearance of rogue waves. Breathers are analytical solutions of the nonlinear Schrödinger equation. The solutions of this equation can be stable or unstable according to the parameter kh which depends on the wave number and the water depth. If kh is lower than a threshold equal to 1.363, the solution is stable. Therefore, the applicability domain of the breather is limited to deep water. However, one may ask, what the evolution of these wave trains is when they enter in the coastal zone. To answer this question, an experimental campaign were conducted at the Tainan Hydraulics Laboratory (THL) à Taiwan.

Unlike the dominant but simplified view of previous scholarship that Chrysostom stands in opposition to Roman property law, his attitude towards Roman law concerning property ownership is quite complicated. Insisting on the belief that things are created for common use and God is the ultimate owner of the world, Chrysostom denies various modes of property acquisition approved by Roman law (inheritance, thesauri inventio, and specificatio ) to be righteous, but when clarifying the limited and inferior human right over things in comparison with that of God, he never hesitates to use the Roman legal terms χρῆσις and δεσποτεία. Moreover, based on the conviction that the worldly economic order derives from divine providence, he confines his enumeration of the things shared in common mainly to the Res communes and Res publicae or Res universitatis under Roman law and persuades his audience to help those in need with the wealth temporarily under their stewardship. As a rhetorical strategy, Chrysostom’s use and manipulation of Roman legal language and thought aimed to promote almsgiving

Social Sciences - Abstract
At present, the effectiveness of English writing teaching for junior English majors is not satisfactory, with a lack of interactivity in the classroom, inflexible teaching methods, a deficiency of targeted teaching for students’ problems, and insufficient emphasis on writing training. The main reasons for these problems are that teachers have failed to conduct the student-centered English writing teaching model, emphasizing one-way output, ignoring students’ writing problems, and resulting in the shortage of writing training. In this regard, teachers need to transform the teacher-centered English writing teaching model, consider students’ actual problems, establish common writing goals, construct online teaching resources for English writing course, and apply multi-modal writing teaching methods to boost the effectiveness of English writing teaching.
