Authors: Li Jiayi
Published: September 2024

With the continuous advancement of global information integration, traditional cultural exchanges between countries are getting deeper and deeper. And the arrival of the new media era, as well as the rapid development of short videos, has brought a new way for cultural cross-border communication, and more and more people learn about the cultures of different countries through the way of new media. New media has the advantages of wide audience range, strong interactivity and fast transmission speed, so it can make an important contribution to cross-border cultural communication. This paper explores the influencing factors of cross-border communication effect of Chinese traditional culture based on regression analysis, in order to provide a faster and more efficient way for cross-border communication of Chinese traditional culture. It is found that content theme, copy duration, title duration, video duration, release time, and copy language affect the horizontal, vertical, and interactive communication of videos to different degrees. Therefore, in the cross-border communication of traditional culture, short video creators want to get better communication effect, they should control the length of the video release and the length of the title, try to compress the length under the condition of complete content and use short and concise title to attract readers to browse, and secondly, due to the time difference of each country and the difference of the language, they should reasonably arrange the release time and the language of copy according to the fans and the audience, and finally, for the copy writing, they should try to be full of details and write a copy in the best possible way. Finally, the copy should be as detailed as possible, so that the users can have a deeper understanding of the charm of Chinese traditional culture.

Authors: Wang Keqiong
Published: September 2024

The modern German philosopher Altu Schopenhauer's philosophy mainly took root and germinated from the Indian Buddhist thoughts of Plato and Kant, and his philosophical thoughts were mainly condensed in his work The World as Will and Appearance. As the first book to understand Schopenhauer, the book is mainly divided into four parts: the world as the appearance of the beginning, the world as the will, the world as the representation, the world as the will. This article is mainly to organize some of the author's feelings after reading the book. Because of the limitation of his own knowledge and Schopenhauer's works tend to be academic obscure, if there is any deficiency, thank the teacher for his criticism and correction.
The Effects of High and Low Context Perception on Second Language Acquirers
Authors: You Jiaxin
Published: September 2024

There is a difference between high-context and low-context cultures, which will bring difficulties to cross-cultural communication, and the study of the difference between high-context and low-context cultures is bound to have important guiding significance for cross-cultural communication and foreign language learning. With the acceleration of globalisation, people have come into contact with the cultures of countries with different contexts and have been subjected to culture shock to a certain extent. In this paper, we start from the comparison between high-context and low-context cultures to explore the cultural conflicts brought about by different contexts and the acceptance of specific behavioural contents under the influence of different linguistic environments (Chinese and English).By analysing the deep philosophical, ethical, and linguistic backgrounds that give rise to conflicts, ways and principles of conducting successful intercultural communication are drawn out.
Spatial Narrative and Identity Constructions in As I Lay Dying
Authors: Zeng Yue
Published: September 2024

As I Lay Dying is a masterpiece by the Southern American writer Faulkner, telling the story of the Bundren family's journey to the town of Jefferson to bury Mistress Addie. Upon its publication, the novel attracted scholarly attention. The novel's characterisation, religious themes and artistic techniques all constitute hotspots of scholarly attention. In contrast, the academia has not paid enough attention to the social factors behind the novel, and the research is not deep enough. In the author's view, My Time to Die not only reproduces the poor life of farmers, but also touches on the game and identity construction between the urban and rural spaces in the American South. In the process of trying to integrate into the town space, the pressures and restrictions experienced by the Bundren family reflect the structural domination of the town over the countryside. The shift of multiple perspectives even breaks the coherence of the narrative, presenting the Bundren family as a fragmented and conflicted underprivileged group, and demonstrating the existential dilemma of rural people in the process of urbanisation. With the in-depth study of narrative space, Long Diyong's theory of spatial narrative provides a new perspective for interpreting As I Lay Dying. Based on this theory, interpreting the spatial elements in the novel in terms of story space, formal space and psychological space can analyze the fate of the characters in greater depth, analyze the character traits, and allow readers to feel the author's writing charm.

This paper analyzes the concept of "reproduction" as a starting point for analyzing Althusser's interpretation of Marx's theory of social formations and describes the theory of the state he constructed on this basis. Althusser's complete and rich theory of the state is an important development of the Marxist theory of the state.
Capabilities and Challenges of Local Governments in Responding to Emergencies
Authors: Shen Jun
Published: September 2024

China is now facing social structure transformation and social structure upgrading, more and more social problems are becoming more and more prominent, so there are more and more public emergencies, and the demand for the government's governance capacity is also higher and higher, and the importance of the local government's ability to cope with emergencies should not be ignored. Emergencies, such as traffic accidents, public health, extreme weather events, etc., often bring huge property losses and casualties to the society, seriously affecting economic development and social security. Under such circumstances, local governments, as the most direct and grass-roots government units, their ability to respond to emergencies is directly related to the control of disasters, the efficiency of rescue and the speed of post-disaster recovery. The study of local government's ability to respond to public emergencies is of great significance in enhancing the credibility of the government and maintaining social harmony and stability. In order to better improve the response capacity of local governments in dealing with public emergencies, this article starts from the theories of public management, and discusses the causes, mechanisms and effects of public emergencies in depth. In addition, the article also points out some challenges faced by local governments in coping with emergencies. Firstly, the early warning mechanism is imperfect, which makes local governments unable to predict and prevent the occurrence of similar events in advance. Secondly, there are insufficient rescue resources, especially in large-scale emergencies, and local governments need more rescue forces and resources to cope with them. Moreover, the lack of public participation is also a problem, which requires local governments to strengthen publicity, education and mobilization to improve the public's awareness of emergency response and self-rescue and mutual-rescue capabilities. Through the in-depth analysis of the collapse of the Jiamusi City Gymnasium, this paper points out the shortcomings of the local government in dealing with public emergencies, so as to provide new ideas for the local government governance, in order to better enhance the government's governance capacity and credibility, and to build a harmonious and stable social environment.
Influence of CO2⁃enhanced Recycled Coarse Aggregate on Durability of Concrete
Authors: Liu Zijian
Published: September 2024

Recycling discarded concrete into recycled aggregates is a very environmentally friendly construction waste disposal method. However, recycled aggregates have performance defects such as low strength and high permeability. The use of carbon dioxide (CO2) mineralization to regenerate aggregates can effectively solve this problem, while also effectively sequestering carbon. However, the durability of concrete made using CO2 mineralized recycled aggregates instead of natural aggregates still needs further research. This article summarizes and analyzes the current research on the durability of CO2 enhanced recycled aggregate concrete, and finds that most of the current research focuses on its chloride ion permeability, while research on its carbonation durability is extremely rare. Therefore, this article analyzes the adverse factors of CO2 mineralized recycled aggregate concrete in terms of carbonation durability and provides suggestions for further research.

Authors: Mao Hanwei , Wang Peng , Zhou Liming , Zhu Zhiren , Ren Xiangmeng
Published: September 2024

In a foggy environment, due to the significant decrease in visibility, the target image captured by the vehicle camera becomes blurred and the information is incomplete, which exacerbates the problem of misdetection and omission in the process of target detection, and poses a serious challenge to driving safety and navigation accuracy. In this regard, a foggy target detection algorithm based on improved YOLOv8 is proposed. First, by introducing a bidirectional feature pyramid BiFPN structure in the backbone network, the algorithm is able to better capture target detection features through bidirectional connections. Secondly, the Shuffle Attention mechanism is added to the neck network to enhance the diversity of the input sequences by randomly disrupting and grouping them, thus improving the performance of the self-attention mechanism, and thus improving the detection accuracy of the network model. The experimental results show that the average accuracy of the improved model on the RTTS dataset is increased by 1.3% mAP@0.5 and 1.2% by mAP@0.5:0.95. In summary, the improved model YOLO_BIS can show good performance when dealing with target detection tasks in foggy scenarios.

Authors: He Shudong
Published: September 2024

In order to clarify the influencing factors and variation rules of gas emission in the excavation face, the 4301-working face of the East Well of Sihe Mine was taken as the research object. Through laboratory experiments, the influence characteristics of coal structure and gas content on gas emission rate were analyzed. Furthermore, the COMSOL Multiphysics numerical simulation software was used to investigate the influence of gas pressure, excavation speed, and soft layer thickness on the gas emission rate of the excavation face. The research results show that the gas emission rate is not only affected by the coal structure and gas content, but also by gas pressure, excavation speed, and soft layer thickness. The amount of gas emission is positively correlated with gas pressure, and the higher the gas pressure, the greater the amount of gas emission. The gas emission rate increases linearly with the excavation speed, and the influence of soft layer thickness on the gas emission rate increases with the increase of excavation speed.

Authors: Liu Zhengting , Li Yunyi
Published: September 2024

Starting from Herbert Marcuse's theory of labour and emancipation, this study critically discusses the dialectical impact of telework on emerging urban proletarian university graduates through ideological analysis and factual case studies. The paper reveals that the apparent advantages of telework in terms of flexibility and autonomy actually obscure the ideological control of technological rationality and the mechanisms of modern capitalist exploitation. The discussion uncovers the unfavourable employment environment of inexperienced new graduates facing career instability, extended labour hours and intrusive surveillance in the context of telework. And it further reveals the importance of promoting social justice to ensure that new graduates can truly achieve labour liberation.

YETİŞKİN BİREYLERDE HEDONİK AÇLIK VE OBEZİTEYLE İLİŞKİSİ
Authors: SEY İKBAL , GÜLER ELİF
Published: September 2024

Beslenme, insan yaşamında temel ihtiyaçların başında gelen kompleks bir davranıştır. Besinler, vücut için enerji kaynağı olmasının yanında birçok birey için
fizyolojik gereksinimleri karşılamaktan daha fazlası haline gelmiştir. Açlık, yiyecek arama davranışlarını uyandıran çoklu motivasyon süreçlerini kapsayan
karmaşık bir durum olarak tanımlanmaktadır. Açlık, homeostatik ve hedonik sistem olmak üzere iki sistemle düzenlenmektedir. Homeostatik ve hedonik
sistemler birbirleriyle daima etkileşim halindedir. Açlık hissiyle birlikte yemek yenilmesi ve doygunluğun hissedilmesiyle yemek yemenin bitirilmesi, enerji
dengesini sağlayan homeostatik sistemler tarafından düzenlenmektedir. Hedonik beslenme ise metabolik ihtiyaç yokluğunda, ödüllendirici, bilişsel ve
duygusal faktörlerle alakalı besinden zevk alma beklentisiyle besin alımını ifade etmektedir. Hedonik açlığın dünya çapında obezitenin hızla artmasında
önemli bir etken olduğu varsayılmaktadır. Obezitede aşırı tüketim ya homeostatik sistemde yemek yemeyi engelleyemeyen bazı bozukluklardan ya da
besinin hedonik yönlerine aşırı tepki verilmesine bağlı olabilmektedir. Hedonik açlık nedeniyle, beslenme sırasında enerji açısından yoğun, şeker oranı
yüksek, kolay ulaşılabilen, büyük porsiyonlarda ve lezzetli seçenekler tercih edilmesi obezojenik bir ortam oluşturmaktadır. Obezitedeki yaygınlığın yüksek
olması ve ağırlık kaybının zorluğu obezojenik ortama atfedilmektedir. Obezojenik yaşam tarzını etkileyen hedonik açlığın ortaya çıktığı an saptanması daha
doğru sonuç vermesi açısından önem taşımaktadır. Hedonik açlığın oluşumunda; bireysel farklılıklar, besinlerin ödül olarak kullanılması, aşırı besin tüketme
isteği, benlik saygısı, dürtüsellik gibi faktörler etkili olabilmektedir. Nöral sistemler ve hormonlar, hedonik olarak uyarılmış besin alımının düzenlenmesinde
rol oynamaktadır. Bunun yanında Dopamin reseptör polimorfizmlerinin de hedonik açlıktaki bireysel farklılıkların değerlendirilmesinden sorumlu olduğu
belirtilmiştir.

A streamlined approach to scale adaptation: Enhancing validity and feasibility in educational measurement
Authors: Du Yiran
Published: September 2024

In educational research, the adaptation of measurement scales to different contexts is necessary but often lacks thorough validation, leading to unreliable and invalid results that compromise research integrity and the effectiveness of educational policies. In this paper, I highlight these issues and advocate for elevated research standards and rigorous validation processes. I propose a practical validation approach that balances feasibility and rigor, including initial content validity checks, pilot testing with small samples, simplified statistical validation, and cross-validation when possible. While practical, this method has limitations, such as potential biases and incomplete psychometric assessments. Despite these, it enhances the reliability and validity of adapted scales, contributing to more robust and trustworthy educational research. By prioritizing meticulous validation, I believe researchers can uphold their ethical responsibilities and advance educational practices and policies grounded in robust evidence.

The results revealed the following: Among the heavy metals, copper (Cu) had the highest concentration across all 40 batches of safflower samples, with mercury (Hg) and lead (Pb) also being relatively high. Safflower samples from Yunnan had significantly higher Hg levels compared to those from other provinces. The levels of Pb and Cu among samples from different provinces were generally not significantly different, while arsenic (As) and cadmium (Cd) levels were either low or undetectable. Among the major elements, potassium (K) had the highest concentration, phosphorus (P) and magnesium (Mg) were lower, and sodium (Na) had the lowest concentration. Safflower samples from Gansu had significantly higher Na and Mg concentrations, and samples from Yunnan and Xinjiang had higher P levels compared to those from other provinces. Safflower samples from Yunnan had significantly lower K levels compared to samples from other provinces, and there were no significant differences in K levels among samples from the other provinces. In the case of essential trace elements, iron (Fe) and boron (B) were relatively high, while nickel (Ni) was the lowest. Safflower samples from Xinjiang and Gansu had higher chromium (Cr) levels, and samples from Gansu had the highest levels of manganese (Mn), Fe, Ni, and strontium (Sr), while samples from Anhui had the highest levels of Zn and B. Conversely, samples from Jiangsu had the lowest levels of Cr, Mn, Fe, and Ni; Gansu samples had the lowest Zn levels; and Yunnan samples had the lowest Sr and B levels. Principal component analysis and cluster analysis showed that safflower samples from the same province tended to cluster together. Specifically, samples from Anhui and Jiangsu clustered closely, samples from Gansu and Xinjiang were relatively close, and samples from Yunnan were more distanced from those of other provinces. This study established a rapid and accurate method for determining the inorganic element content in safflower, and the results indicated notable differences in inorganic element content among safflower samples from different origins.

Inorganic elements play a crucial role in both nutrition and health safety. Analyzing these elements in food helps assess its nutritional value, prevent the consumption of toxic or harmful substances, and understand the extent of contamination to identify and control pollution sources. Additionally, it aids in the production and development of fortified foods, enhances food processing technologies, and improves overall food quality. Therefore, monitoring and detecting inorganic elements during food production is essential. This paper reviews the main methods and characteristics of inorganic element analysis in food, both domestically and internationally, highlighting trends in analytical techniques, including traditional chemical and physical methods, as well as recent advances in nanotechnology and biotechnology. It also summarizes the practical applications of these analytical methods in recent years.
Natural and synthetic cavitands: Challenges in chemistry and pharmaceutical technology
Authors: Martín Carmona María Antonia
Published: September 2024

Supramolecular chemistry involves non-covalent interactions and specific molecular recognition of molecules/analytes by host molecules or supramolecules. These events are present in synthesis, catalysis, chiral separations, design of sensors, cell signaling processes and drug transport by carriers. The typical behavior of supramolecules is derived from their ability to build well-structured self-assembled and self-organized entities. Cavitands are a particular group of supramolecules possessing a cavity capable to include a variety of compounds thanks to host-guest non-covalent interactions developed among cavitands and analytes. Some typical cavitands are crown ethers, calixarenes, cucurbiturils, porphyrins and cyclodextrins. The two latter families are natural product cavitands that are generally considered models for molecular recognition of cations and organic and inorganic guest molecules, being attractive host molecules from the sustainability point of view. The natural cyclodextrins (α, β and γ-cd) are obtained with reasonable cost by enzymatic treatment of starch under adequate temperature conditions. They are profusely used in pharmaceutical, food and cosmetic industries due to their very low toxicity and side effects. This review is focused on the relevance andapplications of cyclodextrins in pharmaceuticaltechnology for their ability to increase solubility and stabilize drug molecules, thereby enhancing their bioavailability. The association of cyclodextrins with diverse nanostructured materials, i.e., carbon nanotubes, magnetic nanoparticles, silica and molecularly imprinted polymers, allows to synergize the properties of cyclodextrins and these nanostructured materials to reach highly specific molecular recognition of analytes. The exploitation of these benefits for analytical sample pre-treatment and chiral chromatographic separations are described. The use of cyclodextrins as mobile phases additives in hplc provides interesting results for green and sustainable chromatographic separations. Polymers incorporating cyclodextrins show exceptional adsorption properties for retaining toxic compounds and persistent organic pollutants from soils and water samples, allowing satisfactory recoveries of these environmental samples according to the stockholm convection principles.

In this study, water-soluble copper-doped carbon nanodots (Cu-CDs) with high fluorescence quantum yield were synthesized using a one-step hydrothermal process with citric acid and ethylenediamine as precursors and copper sulfate as the dopant. A novel fluorescence-based method for detecting anthrax biomarkers was developed, leveraging the strong chelation of 2,6-pyridinedicarboxylic acid (DPA) with the carbon nanodots. Under optimal conditions, the fluorescence quenching rate of Cu-CDs with DPA exhibited excellent linearity in the concentration ranges of 5–100 nmol/L (r² = 0.9941) and 150–400 nmol/L (r² = 0.9976), with a detection limit of 2.3 nmol/L. The method's low cost, high specificity, sensitivity, and simplicity suggest promising potential for anthrax biomarker detection.
