Self-employed Work in Northeast China County Regions: From Traditional Workers to Store Owners

Jing Ning — 2024-06-07

Northeast China has experienced economic and industrial transformation, especially in the county regions. More and more self-employers are arising in the Northeast County regions. After the reform and marketization, the stable working space once constructed by the national capital quickly lost its advantage and disappeared. Now there is nearly no industry in most counties of Northeast China, so laid-off workers who stay there are widely forced to employ themselves in self-owned businesses. They are using small family capital to create new working spaces in the store, and at the same time create new ways of working and social relationships. The new working and living spaces are highly embedded into each other, which means an integration of store and family. Their daily life, family, and social relations are all closely connected with working. They are also continuously reproducing a stable structure of working and living by intergenerational succession.

Comparative Analysis of Chloroplast Genome Variation and Evolutionary Analysis of the Endangered Species Dendrobium flexicaule and its Relative Species

Le Wang — 2024-06-13

Globally, the genus Dendrobium (Family: Orchidaceae) exhibits widespread distribution, predominantly occupying the tropical and subtropical areas of Asia. Although the chloroplast genomes (cpDNAs) of certain Dendrobium species have been documented, the evolutionary relationships among these species remain largely unexplored. In this pioneering investigation, a comprehensive analysis of the complete cpDNAs from Dendrobium species is presented, including Dendrobium flexicaule along with three closely related taxa (D. nobile, D. officinale, and D. huoshanense). The size of the novel complete cpDNAs ranged from 150,529 to 152,588 bp, and their cpDNA structure exhibits a unique quadrifoliate structure reminiscent of female quadrivalents, including large single copy, small single copy (SSC), and inverted repeat regions. A total of 175 simple sequence repeats were identified in the D. flexicaule cpDNA. A few pseudogenes of the NA(D)H dehydrogenase-like (NDH) genes were found in the annotated cpDNAs of the four Dendrobium species. Within the shared pseudogenes ndhF and ndhG, ndhF frequently undergoes mutations. Additionally, the phylogenetic analysis showed that D. flexicaule and D. scoriarum were close sister species. The research findings provide crucial genetic information for the molecular phylogenetic system of D. flexicaule.

A Study on Nyonya Food Culture from the Perspective of Cross-Cultural Adaptation Theory

Jiejing Tang — 2024-06-07

Nyonya food culture is a unique blend of Chinese and Malay culinary traditions. Drawing from John Berry’s cross-cultural adaptation theory, this paper delves into the formation, development, and dissemination characteristics of Nyonya cuisine. The analysis reveals that the Chinese immigrants in Malacca primarily adopted an integration strategy during their cross-cultural adaptation, which is evident in the localization of food ingredients, cooking techniques, taste preferences, and dining etiquette. As a symbol of food culture, Nyonya cuisine has played a crucial role in helping the Nyonya ethnic group establish their identity in Southeast Asia, where diverse ethnic groups coexist. Furthermore, as a product of cross-cultural exchange, Nyonya food’s inherent adaptability and integration have made it an essential medium for fostering intercultural communication and understanding.

Study on the Area of Waiting Space in the Old Area of a Tertiary Hospital Based on AnyLogic Simulation

Jing He — 2024-06-07

The waiting space is the place where patients stay the longest during the entire medical treatment process, and the adequacy of its spatial area to the number of waiting patients has a significant impact on the treatment experience. Due to the continuous expansion of the medical scale and the increasing outpatient volume, congestion in the waiting areas of the old area of tertiary hospitals in Guangzhou is common, seriously reducing patients’ medical experience. Therefore, it is necessary to determine the optimal waiting area space in the old area based on the number of consultation rooms and evaluate the current situation of the waiting area to optimize the waiting area reasonably. Taking the Third Affiliated Hospital of Sun Yat-sen University as an example, this study determines the daily outpatient volume of departments under specific consultation room numbers, uses AnyLogic to simulate the medical treatment process of patients, outputs the change in the number of patients in the first waiting area. Based on the mean and peak number of waiting patients during peak hours, the study calculates the areas required for “generally adequate” and “specially adequate” waiting space respectively. These are then compared with the current area to evaluate the adequacy of the current waiting space.

The results of FTIR and SEM analysis showed that the sand chaff was involved in the agglomeration process of sand, and the sand and the chaff were well combined, with a better spatial network structure and surface morphology. Therefore, it is a great prospect to explore the reuse of solid waste of fungal bran in desert afforestation.

The Effect of Herding Behavior on the Efficiency of Pedestrian Evacuation in Subway Stations

Yushun Bao — 2024-06-07

In the emergency evacuation of pedestrians in subway stations, most people do not know the correct evacuation routes and methods, and tend to follow others blindly, resulting in herding behavior. To study the process of pedestrian evacuation with herding behavior in subway stations, a cellular automata pedestrian evacuation model is established to simulate the pedestrian evacuation with herding behavior in subway stations, and the effects of the weight coefficients of the parameters in the model on the overall evacuation time and the distribution of people’s positions are investigated to quantify the effects of herding on the efficiency of the pedestrian evacuation and the movement behavior. The simulation results show that moderate (k_C < 40) crowd behavior can play a beneficial role in reducing reaction time and guiding the direction of evacuation; on the contrary, excessive crowd behavior (k_C > 40) will lead to an increase in evacuation time and a decrease in evacuation efficiency. The conclusions presented in this paper can help to improve the efficiency of pedestrian evacuation in emergencies and provide a theoretical basis and practical guidance for the management of safety evacuation in subway stations.

Civil Diplomacy and Civil Society Breaking the Traditional Diplomatic Model: A Case Study of Civil Organizations and Civil Diplomacy in Chinese Society

Zhuanghong Tong — 2024-06-07

Civil society organizations and Civil Diplomacy are some of the important research contents of diplomacy, as well as the emerging diplomatic groups and organizations in the post-epidemic era. Broadly speaking, civil society organizations refer to social intermediary organizations other than government parties, enterprises, and institutions. The development of China’s civil diplomacy is a multi-dimensional and multi-level process, that plays an important role in China’s diplomatic system, and its development not only reflects the changes in China’s relations with the world but also the transformation of China’s foreign policy and the construction of great power diplomacy with Chinese characteristics. In the past, national and international organizations that participated in diplomatic activities in the image of the state did not have the figures of civil organizations. After the epidemic, more and more civil organizations express their political positions and values through the power of public opinion and the media to indirectly change the pattern of the international community, and use their power to enhance the soft power of official diplomacy, which has become an indispensable voice and force in today’s international community. Here, this paper will take Chinese civil diplomacy and civil society as examples to analyze the reasons, impacts, and prospects of the development of civil diplomacy in international governance.

Cultural Communication and Cross-Cultural Communication in Script Translation

Chunmeng Zuo — 2024-06-07

As a kind of cross-cultural communication, translation is the information exchange between two different cultures. In cross-cultural translation, the translator should try to match the translated language and the translated language culture. The translator should not only pay attention to the meaning of the original text, but also pay attention to the cultural connotation of the target language, and achieve the organic combination of the two. To achieve this purpose, translators must take the source language as the starting point, and comprehensively restore the vocabulary, the sentence pattern, the structure, the emotion, and the way of thinking of the source language. When translating the original text, the cultural information contained in the source language should be integrated with the translation according to the characteristics of the translated language environment and the audience. From the perspective of the translation of the drama script, this paper discusses cultural exchange and cross-cultural exchange, hoping to be helpful to the peers.

Jessica Sosa Carpio — 2024-06-07

Both education and its quality supply are closely linked to employability and labour productivity. The present study aimed to analyze the contribution of the level of teacher qualification on the employability variable in African economies, for the period 2016–2020. Regarding the methodology, a quantitative analysis of the data was conducted through the Generalized Method of Moments in Differences, two stages and with standard error correction. Based on the results, it was possible to determine the existence of a negative, inverse and significant relationship between the degree of qualification of teachers on the unemployment rate; therefore, it could be concluded that a higher level of qualification of teachers has a direct contribution on the increase in the levels of employability for the African business sector. Through the results of Hansen’s Test (P-value = 0.540), the validity of the model’s specificity in terms of instrument utilization was tested. Based on the first (P-value = 0.009) and second order (P-value = 0.148) autocorrelation tests, the validity of the consistency of the Generalized Method of Moments econometric estimators in differences, two stages and with corrected standard errors was tested.

Application of Spray Coating in the Fabrication of Free Standing Nanocellulose Films and Barrier Coating on the Paper Substrates

Kirubanandan Shanmugam — 2024-06-11

Spray coating is a novel concept for fabricating free-standing film and producing barrier coating on paper substrates. The spraying gives comparable efficacy with vacuum filtration in terms of operation time, film quality, and process intensification approach. The smooth films created by spraying nanocellulose onto the polished impermeable surface could serve as a platform for a variety of sustainable functional devices. Finally, the application of spray-coating barriers and nanocellulose films on paper substrates is the focus of the spray-coating concept designed to create smooth nanocellulose films. One of the most important factors that affect the performance of different cellulose-based functional materials is the smoothness of nanocellulose film coated with sprays in the production of flexible and printed electronics. The uses of nanocellulose film as a high-performance barrier material and the possible replacement of synthetic plastic packaging are expanded by spray coatings. The process of creating a nanocellulose film using spray coating takes less than a minute. Compared to vacuum filtering, this method offers excellent speed potential for nanocellulose films. The wet layer of spray coating takes more than 24 hours to dry in a controlled laboratory environment, using air drying. Future research projects will improve the drying process of wet films. The film spray process serves as a proof of concept, and the quality of the film produced by this method contrasts with vacuum filtration. Studying spray coating wet film drying outside the scope of this research is not part of the scope of this study, and additional research is needed in this area. The shiny film that is created by spraying nanocellulose on the impermeable polished surface can serve as a platform for various sustainable functional devices.

Interpreting the Symbolism of “Flowers” in Sons and Lovers by David Herbert Lawrence

Xuanxuan Zhong — 2024-06-07

David Herbert Lawrence is one of the major writers of 20th-century English literature. His representative works include Sons and Lovers, The Rainbow, and Women in Love, which cover different fields such as novels, poems, essays, and dramas. He is known for his depiction of human emotions, sexuality, and social issues. His novel Sons and Lovers uses symbolism skillfully and intensely, in which darkness, coal mine, sunset, the moon, flowers, and so on are imagery. The use of this imagery profoundly reveals the complex emotions and feelings of the characters, thus better interpreting the various psychological activities deep inside the characters as well as the complex relationships between the characters. This paper contains two parts. The first part discusses the functions of symbolism in this novel, including four aspects: enriching the meaning, revealing the characters in depth, intensifying the emotional experience, and focusing on the theme. The second part focuses on the three aspects of the symbolism represented by the “flowers”, namely, the “flower” as a symbol of family, the “flower” as a symbol of freedom, and the “flower” as a symbol of growth and change. Through these interpretations, this study hopes to interpret the main idea of the novel in a deeper way and to enable readers to have a better understanding of the characters, the plot, the relationship between the characters, and the use of symbolism in the novel.
