Authors: Li Yunzi , Shi Zheng
Published: February 2024

International students are a bridge between Chinese and foreign cultures, but they still face multiple dilemmas in Chinese cultural communication due to different cultural backgrounds and values. In this paper, we utilize the subsumption sorting algorithm to sort the amount of cultural communication of international students’ exchanges, which is dynamically switched by a combination of two methods: back-block forward interpolation and header exchange. The D-S monopolistic competition model is used to construct the theoretical model of international student exchange that affects China’s international cultural communication power. The CES utility function is used to construct China’s international cultural communication network, which calculates the total amount of communication culture of cross-cultural exchanges between international students. In the end, an analysis of 85 international student samples revealed a correlation between international student exchanges and China’s international cultural communication. The results show that the correlation coefficient between international student exchanges and China’s international cultural communication is 0.305 p > 0.05, indicating that international student exchanges have a positive promotion effect on China’s international cultural communication. This study examines the general law of international cultural communication, which is crucial in promoting Chinese culture worldwide.

Research on the Protection and Dissemination of Intangible Cultural Heritage with Regional Cultural Characteristics in Shaanxi under the Background of Big Data
Authors: Wang Xinglu
Published: February 2024

Cultural heritage is a response to the characteristics of a society and deserves to be protected and passed on to future generations, but there is still a lack of knowledge and skills related to it in the methodology of digital preservation of intangible cultural heritage. This paper aims to digitally preserve intangible cultural heritage in Shaanxi by utilizing methods such as feature point description, image edge detection, and visual feature extraction. The scale space expression algorithm is applied to keep the feature point scale of the intangible cultural heritage unchanged, and the scale space of the image is obtained by convolving the Gaussian convolution kernel with the image. The Sobel operator is employed to evaluate the significance of pixels in the non-heritage image to identify the edge effect of the image. Focusing on analyzing the digitization types of Shaanxi’s non-legacy, we explored the role of images in the protection of non-legacy and formulated the dissemination path of Internet+Non-legacy for the current situation of Shaanxi’s non-legacy. The results show that among the 12 NHs in Shaanxi, the number of textual materials is the largest, accounting for 43.33% of all digital materials, followed by the proportion of images at 33.33%, and the current digitization of NHs needs the supplementation of audiovisual materials the most, with audiovisual materials accounting for only 23.33%. The value of images for the protection of non-heritage cultural heritage reflects the non-heritage characteristics intuitively, and the range of Shaanxi non-heritage image dissemination index is in the range of 21-89 interval, and with the change of time, people pay more and more attention to Shaanxi non-heritage.

Authors: Kang Heyan , Kim Kiesu
Published: February 2024

With the rapid development of Internet media in recent years, the main position of IP promotion and dissemination of urban regional culture has shifted from traditional media to new media mainly based on mobile Internet. This paper takes the viewpoint evolution model as a research tool, decides the best choice for decision-making based on the quality value of the main evidence, and adjusts its viewpoint using Bayes’ rule. The analysis includes both positive and negative perspectives on the issue of promoting regional cultural communication in second and third-tier cities through IP promotion and integrated media. Finally, we discuss the mechanism of the communication of the regional culture of second and third-tier cities through the integrated media and analyze the influence of the integrated media communication effect on the regional culture of second- and third-tier cities through the Bayesian model of improving the evolution of viewpoints. The results show that in the process of evolution, the group of people who agree with the positive view is 0.483, while the group of people who hold the negative view is only 0.223. In addition, ‘Culture X’s’ enhancement through the melting media has resulted in a nearly 1.8 million increase in the number of cultural program broadcasts on the entire network. The best way to combine the advantages of both is to promote regional culture in second and third-tier cities through integrated media, as suggested by this. This study has the potential to provide an optimization strategy for promoting and disseminating regional culture in second and third-tier cities, which has significant strategic value.

Published: February 2024

We examine how generations X, Y, and Z might react to market-moving events over short- and long-term horizons to maintain an optimal balance among risk, return, and investor preferences. To analyze various portfolio variants, we use data on selected global assets and several types of economic and non-economic events for 2000-2021H1, applying the mean-variance optimization procedure. According to our results, in optimal portfolios, fixed-income assets dominate and are the main driver of portfolio adjustments. Portfolios with short-term horizons with less risk-averse investors and those for generation Z are the most reactive to analyzed types of events. None of the eventsper secreates an extraordinary opportunity to increase returns. However, expansionary monetary policy generates the greatest potential for incremental returns. Our findings provide practical implications for investors on how to adjust their portfolios in response to significant market events.

Published: February 2024

Integration in association – critical reflections on a project.
This article discusses integration as a process rather than as a result or as a system of distribution, and takes its cue from Lave & Wenger’s concepts of “situated learning” and “legitimate peripheral participation”. By using integration as a process related concept the article analyzes both the intentions of an integration project as well as its consequences. The intention of the project was to simplify the integration of new members of the Swedish society by funnelling them into existing associations and clubs of their own choice in order to open up the considerable amount of social net works connections to these associations and clubs through their members. By becoming members of Swedish associations and clubs newcomers would also become aware of the importance of representation in Swedish society. The authors too see this result as an important step in the process of integration from a legitimate peripheral position towards the ever changing centre, e.g. integration as a result of various situated learning.

Published: February 2024

The aim of the present article is to describe how the local environment affects people and how people can have an impact on their local environment. Using the sports movement as an example, the article discusses the importance of getting citizens to participate and to play an active role in decision processes concerning physical planning for the local environment. How we design our outdoor environments largely determines how our children develop in terms of their motor coordination and self-image, and thereby also their mental status, concentration ability, and academic aptitude as well as our children’s resources for engaging in one or several athletic activities that promote life-long amusement, good health and well-being. For young people, the opportunity to spontaneously use their local environment is a basic need, one that has received too little attention in city planning, e.g. fill in projects. Politicians are sensitive to public expressions of opinion. If it unites its power, the sport clubs and sport federations should be able to ensure high quality play environments for children and spaces for spontaneous sports activities for youth. The new trend towards private-public-partnership means a great deal of negotiations between the developer and the city leadership in which citizens have no access. It takes place behind closed doors and the child perspective is often forgotten. The sport clubs and sport federations have a chance to take the initiative here by formulating goals for children’s and young people’s motor, social and cognitive development and by pushing its own proposals for developing the local community.

Computational Analysis and Regression Laws for Nozzle Erosion Prediction in Hybrid Rockets
Authors: Rotondi Marco , Migliorino Mario Tindaro , Bianchi Daniele , Kamps Landon , Nagata Harunori
Published: February 2024

The erosion of the nozzle throat can represent one of the major limitations against the future widespread use of hybrid rocket engines (HREs) in the space industry. In fact, nozzle erosion in HREs can be more severe and harder to predict than in solid rockets due to the higher concentration of oxidizing species in the combustion products and to mixture ratio shifts and/or throttling. Therefore, an accurate understanding of the erosion phenomenon is of fundamental importance for the technological advancement of HREs. This work is focused on the investigation of graphite nozzle erosion in HREs burning high-density polyethylene with two different oxidizers, oxygen and nitrous oxide. First, the results of a computational fluid dynamics parametric analysis are used to derive closed-form regression laws for the rapid estimation of nozzle throat erosion and wall temperature depending on chamber pressure and mixture ratio. Then, a one-dimensional transient heat conduction solver is loosely coupled with the aforementioned regression laws, allowing to reconstruct the transient heating process within the solid. The obtained numerical results are validated against experimental data. Finally, the effect of gas-phase reactions on the heterogeneous reactions occurring at the nozzle surface is highlighted when moving from fuel-rich to oxidizer-rich conditions.
Application of Linear Mixed-Effect Modeling for the Analysis of Human-in-the-Loop Simulation Experiments

Published: February 2024

A real-time human-in-the-loop (HITL) simulation is a crucial validation activity in the life cycle of air traffic management operational concept development. When planning HITL simulations, however, researchers face a series of experimental design constraints that often limit the application of advanced statistical data analyses. Linear mixed-effects modeling (LMEM) is a multiple regression analysis technique that is comparatively flexible in considering the covariance present in repeated measures data. This paper aims to make LMEM better known to applied researchers in the field of aviation research, particularly those applying HITL. For this purpose, the building steps of LMEM, the output, and model-fit tests are explained based on data obtained from an Airbus 320 flight simulation study that examined the impact of two different wake separation schemes on either a final approach or a departure path on the pilots’ perceived severity of a wake-vortex impact. The experimental setup involved six experimental factors that were not fully crossed, had an unbalanced number of repeats per pilot, and contained missing data. This prevented the use of the more traditional repeated measures analysis of variance. The LMEM was able to handle this and could explicitly test the study hypotheses with statistical confidence.
Free Vibration of a Panel Supported by a Shear Compliant Two-Flexure Hinge
Authors: Yasara Dharmadasa B. , Mejia-Ariza Juan , Sauder Jonathan , Focardi Paolo , Case Bradford Samuel , Arya Manan , López Jiménez Francisco
Published: February 2024

Elastically deformable hinges or deployable booms commonly follow architectures with face-skin layers only, cutting out the core to facilitate folding. This significantly reduces the shear stiffness of the hinge, which might reduce the first resonance frequency of the structure. We rationalize the free vibration of the system and the interplay between shearing and bending deformation by deriving an analytical formulation using Timoshenko’s beam theory. The framework is derived for a general beam and applied to a case of two flexures of arbitrary geometry with no core. Investigating the specific geometry of flat flexures reveals the existence of two nondimensional length ratios that capture the interplay between inertia, bending stiffness, and shear stiffness of the hinge. Our model explains the dependence of the frequency on the parameters of the system, as well as the dimensions that determine the transition between bending- and shear-dominated vibration modes. Comparison with finite element simulations shows that our analytic framework is able to predict the first natural frequency with less than 1% error. Additionally, an experimental validation was carried out using steel flexures and acrylic panels, showing good agreement with the predictions.

Published: February 2024

The fact that there are continued public reports of abuse and violence against women and young girls in South Africa, and elsewhere in the global village, is enough to underline that gender-based violence (GBV) is profoundly entrenched in social and human settings. Considering this, it stands to reason to recurrently contest this challenge relying on isiXhosa literature, among other mechanisms. In fact, violence against women and young girls has been regarded by several scholars, government and non-governmental organisations, and community members as an international crisis. On account of this, this article critiques how self-defence and battered woman syndrome (BWS) are reproduced in a selected isiXhosa short story titled “Umfazi Akayongqongqo” (A woman is not a punching bag). This short story is recognised herein as a primary source of data, while African feminist theory is applied to uncover the complexities pertaining to self-defence and BWS as they emerge as a direct consequence of prolonged incidents of GBV. The findings and discussions indicate that prolonged occurrences of abuse and violence towards women and young girls have the potential to lead to situations where victims of GBV cannot tolerate it any longer, hence resulting in retaliation, self-defence and BWS. While there are contrasting views concerning self-defence and BWS, particularly within the legal frameworks, this article underlines the necessity to strike a balance between these important social, cultural, and political issues in a bid to reasonably solve the conundrum—GBV. The concluding remarks present possible future scholarly discourses that may be considered in an attempt to address this challenge. For instance, it would be prudent to consider ways to decolonise isiXhosa literary scholarship, focusing on re-evaluating traditional canons, challenging Eurocentric voices and promoting indigenous African knowledge systems (IAKS). By the same token, it would be perceptive to examine how isiXhosa literature mirrors and responds to the legacies of colonialism, including matters related to identity, language, and cultural representation.

Entrepreneurship initiatives have undeniable effects on national economies. States and governments produce various strategies and policies to increase the contribution of entrepreneurship to the country's economy. Entrepreneurship levels of countries are determined by various organizations. Country entrepreneurship scores and rankings are regularly published by the “Global entrepreneurship monitor (GEM)”. Countries, on the other hand, understand their current level of entrepreneurship according to these reports. In this research, it is aimed to determine the entrepreneurial activity efficiency levels (EAE) of the countries with the data obtained from the GEM 2021 reports and to cluster them according to their activity levels. In this context, forty-two country data of five indicators presented in the 2021 GEM report were used. The research was carried out in two stages. In the first stage, four output-oriented data envelopment (DEA) models were created and the EAE were determined. In the second stage, the clustering of countries according to their EAEs was carried out by hierarchical clustering analysis. According to the research findings, 21 countries were at full efficiency in the DEA-1 model, 22 countries were at full efficiency in the DEA-2 model, and 18 countries were at full efficiency in the DEA-3 and DEA-4 models. In the hierarchical clustering analysis, the countries are clustered in three groups. Twenty-two countries were included in Cluster-1, seven countries in Cluster-2, and thirteen countries in Cluster-3. Cluster-1, Cluster-2 and Cluster-3 were characterized as high, middle, and low efficiency levels, respectively. As a result of the research, suggestions were made to countries to improve their entrepreneurial activities.

Background Problems: The precision of serves in volleyball plays a crucial role in shaping the outcome of a match, potentially altering the game's dynamics, scoring points, and elevating the overall team performance. Research Objectives: This study was conducted to assess the impact of targeted overhand serve drill exercises on overhand serve accuracy. Methods: This study employed a quasi-experimental approach, utilizing a one-group pretest-posttest design, with 30 volleyball extracurricular participants engaging in targeted overhand service drill exercises over 6 weeks. Data were collected using the AAHPER overhand serve accuracy test, followed by analysis through a paired-sample t-test to assess the effectiveness of the training and determine if there were any differences in outcomes between the two groups, with a significance level set at 5%. Before conducting parametric tests, data normality is examined using the Shapiro-Wilk test, and homogeneity is assessed using Levene's test. Findings and Results: In summary, the finding of this study showed that targeted overhand serve drill exercises have a positive effect on enhancing the accuracy of overhand serves in volleyball extracurricular participants. Conclusion: In addition, this intervention can be a valuable training method and reference for designing training programs aims at improving overhand serve accuracy in volleyball matches. Future research should implement stricter controls throughout the experimental process.
