Investigating the relationship between goal orientation, self-efficacy, positive emotionality, and affective engagement among Chinese students.

This study delved into the complex interplay between self-efficacy, achievement goals, positive emotions, and affective engagement among university students in China. To achieve this, a stratified random sampling technique was employed, resulting in a sample of 391 students from four geographically distinct universities across China. The data collection relied on self-reported questionnaires that measured academic self-efficacy, goal orientation (specifically focusing on mastery versus performance goals), positive emotions, and various aspects of affective engagement, including enjoyment, satisfaction, and interest in learning.

Analysis on the spatiotemporal pattern and driving force of the spatial deviation index of grain and economy in counties in China.

Studying the spatial relationship and driving forces between grain production and economic development in China can assist in the coordinated development of economic growth and grain production in both China and other developing countries. Based on panel data from 2000 to 2019 covering 2018 county-level units in China, this study comprehensively investigated the spatial distribution, spatial differences, dynamic evolution of distribution, and driving factors of China's county-level spatial deviation index of grain and economy (SDIGE) using methods such as the standard deviation ellipse method, the three-stage nested decomposition of Theil index, kernel density estimation, and geographically weighted regression (GWR) model. The results show that (1) from 2000 to 2019, China's SDIGE showed a development trend of "up-down-up," and the highest SDIGE was in the northeast region, the lowest in the east region, and the spatial pattern of "high in the northeast-low in the east coast" was increasingly prominent.

An investigation into academic burnout, enjoyment and engagement in EFL learning among Chinese junior high school students.

With the booming of Positive Psychology, a growing scholarly interest has emerged in language learners' psychological well-being. However, limited research has been conducted on the emotions of Chinese EFL learners. Therefore, this study aimed to quantitatively examine the burnout, enjoyment, and engagement levels among 387 junior high school EFL learners.

Research on the design of panoramic virtual learning environment screen elements.

Panoramic video and virtual reality technologies create learning environments that provide learners with an "immersive" experience. In recent years, panoramic video design to create immersive learning environments, in particular, has become an increasingly popular topic in teacher education and educational research. However, few studies have explored the elements of panoramic virtual learning environment screens regarding the design of learning environments.

Digital marketing program design based on abnormal consumer behavior data classification and improved homomorphic encryption algorithm.

This article endeavors to delve into the conceptualization of a digital marketing framework grounded in consumer data and homomorphic encryption. The methodology entails employing GridSearch to harmonize and store the leaf nodes acquired post-training of the CatBoost model. These leaf node data subsequently serve as inputs for the radial basis function (RBF) layer, facilitating the mapping of leaf nodes into the hidden layer space.

ARIAS: An AR-based interactive advertising system.

In this paper, we present an interactive advertising system based on augmented reality(AR) called ARIAS, which is manipulated with gestures for displaying advertising videos. Two-dimensional markers are defined in the system. The system captures the frame data through the camera in real time, uses OpenCV library to identify the predefined markers, and calculates the pose of markers captured by the camera.

Optimal Decision-Making of Closed-Loop Supply Chains in E-Commerce Platform Considering Sales Cooperations under Environmental Effects and WEEE Regulations.

Nowadays, to achieve carbon neutrality, e-commerce platforms participate in the sales and recycling of electrical and electronic products in consideration of waste electrical and electronic equipment (WEEE) regulations and environmental effects. This study builds a Stackelberg game model for an e-commerce closed-loop supply chain (ECLSC) under different sales cooperation modes between a manufacturer of electrical and electronic products and an e-commerce platform. Reverse induction is used to obtain the optimal decision-making and profit of the ECLSC under three sales cooperation modes, considering the influence of environmental effects on optimal decision and objective functions.

The Seismic Performance of New Self-Centering Beam-Column Joints of Conventional Island Main Buildings in Nuclear Power Plants.

In order to improve the deformation energy consumption and self-centering ability of reinforced concrete (RC) frame beam-column joints for main buildings of conventional islands in nuclear power plants, a new type of self-centering joint equipped with super-elastic shape memory alloy (SMA) bars and a steel plate as kernel components in the core area of the joint is proposed in this study. Four 1/5-scale frame joints were designed and manufactured, including two contrast joints (a normal reinforced concrete joint and a concrete joint that replaces steel bars with SMA bars) and two new model joints with different SMA reinforcement ratios. Subsequently, the residual deformation, energy dissipation capacity, stiffness degradation and self-centering performance of the novel frame joints were studied through a low-frequency cyclic loading test.
