    Abstract "As China has undergone rapid urbanization and population aging in the past few decades, improving the welfare of older people in rural areas has become an ever more pressing issue. This title is the first book-length work to examine the influence of urbanization on the mental health of China's older population outside the city. Incorporating the theoretical framework of social ecology, the author analyzes the socio-cultural factors that have exerted an impact on participants' mental health, such as their personal life course transition, changes to family living arrangements and community restructuring. Moreover, he introduces several elderly mental health intervention models in China, while evaluating the policy initiatives that have developed based on China's local resource sufficiency, cultural customs, and older people's needs. The research findings not only facilitate a deeper understanding of China's welfare policy making, but also offers a useful reference for countries that are experiencing similar urbanization and population aging and that wish to formulate better social policies. Students and scholars of social policy, welfare, and gerontology will find this title to be essential reading"--

    Abstract Acidizing operation is normally applied in low permeability reservoirs, but if the acid system is not utilized properly, it will cause sensitive damage to the reservoir. As for the Sanjianfang Formation of the sandstone reservoir in the Shanshan oilfield, the problems existing in acidizing are especially serious. For these problems, the basic characteristics, sensitivity characteristics, and damage mechanisms were obtained by means of X-ray diffraction (XRD) analysis and scanning electron microscopy. Meanwhile, gas porosity and permeability were measured, and reservoir sensitivity characteristics were evaluated. The results showed that the reservoir rocks are mainly feldspar lithic sandstone and the clay minerals are mainly kaolinite and montmorillonite, which belong to the high clay mineral reservoir. It is an unsaturated reservoir with normal formation pressure that has low porosity and ultra-low permeability, heavy crude oil, and low porosity. The reservoir is highly stress sensitive, moderately weak velocity sensitive, alkali sensitive, water sensitive, salt sensitive, and weak acid sensitive. Based on these results, a multinanoscale stimulating liquid system was developed in the laboratory, and field application of this fluid system combined with mud acid was carried out. The combination system of multinanoscale highly efficient stimulation fluid and mud acid can meet the optimal dissolution rate of rock during the acidizing process and can increase the permeability of the targeted reservoir by 2.68 times, with a remarkable field application effect. The research results can provide a scientific basis for acidizing and stimulation of ultralow permeability sandstone reservoir.

    Abstract Taking the data of 30 provinces (excluding Hong Kong, Macao, and Taiwan regions and Tibet) at the provincial level from 2010 to 2019 as the research object, this paper analyzes the current situation and characteristics of China's agricultural modernization and response to carbon emissions. Agricultural modernization is decomposed into production modernization, management modernization, and ecological modernization. This study uses the spatial Dobbin model to demonstrate the impact of agricultural modernization on carbon emissions and analyzes the impact of agricultural modernization on carbon emissions in the East. The direct effect and spatial spillover effect of the three western regions are to different degrees. The results show that agricultural carbon emissions are spatially dependent. The development of agricultural modernization and transportation of neighboring provinces and cities will have an impact on agricultural carbon emissions in this region. Therefore, under the background of rural revitalization and low-carbon agriculture, this paper further analyzes the impact of agricultural modernization on the spatial distribution of carbon emissions in the eastern, central, and western regions. Recommendations are proposed with a view to giving better play to the process of agricultural modernization.

    Abstract With a 10 years development, chiral spirocyclic phosphoric acids (SPAs) have attracted a substantial amount of attention from the synthetic organic chemistry community. This kind of small molecule organic catalysts has some advantages like easy to obtain, no transition metal and wide application range. Because of avoiding the use of toxic substances which are limited in the process of drug synthesis, a large number of studies pay attention to the key structures (such as indole, carbozole.) containing pharmacological active components in natural products. And most of them get a excellent result in yields (more than 80% yield) and enantioselectivities (more than 90% ee). These studies can provide new pathways to nature products.

    Abstract Accurately detecting student behavior in classroom videos can aid in analyzing their classroom performance and improving teaching effectiveness. However, the current accuracy rate in behavior detection is low. To address this challenge, we propose the Student Classroom Behavior Detection method, based on improved YOLOv7. First, we created the Student Classroom Behavior dataset (SCB-Dataset), which includes 18.4k labels and 4.2k images, covering three behaviors: hand raising, reading, and writing. To improve detection accuracy in crowded scenes, we integrated the biformer attention module and Wise-IoU into the YOLOv7 network. Finally, experiments were conducted on the SCB-Dataset, and the model achieved an mAP@0.5 of 79%, resulting in a 1.8% improvement over previous results. The SCB-Dataset and code are available for download at: https://github.com/Whiffe/SCB-dataset.

    Abstract The use of deep learning methods for automatic detection of students' classroom behavior is a promising approach to analyze their class performance and enhance teaching effectiveness. However, the lack of publicly available datasets on student behavior poses a challenge for researchers in this field. To address this issue, we propose a Student Classroom Behavior dataset (SCB-dataset) that reflects real-life scenarios. Our dataset includes 11,248 labels and 4,003 images, with a focus on hand-raising behavior. We evaluated the dataset using the YOLOv7 algorithm, achieving a mean average precision (map) of up to 85.3%. We believe that our dataset can serve as a robust foundation for future research in the field of student behavior detection and promote further advancements in this area.Our SCB-dataset can be downloaded from: https://github.com/Whiffe/SCB-dataset

    Abstract Accurately detecting student behavior from classroom videos is beneficial for analyzing their classroom status and improving teaching efficiency. However, low accuracy in student classroom behavior detection is a prevalent issue. To address this issue, we propose a Spatio-Temporal Attention-Based Method for Detecting Student Classroom Behaviors (BDSTA). Firstly, the SlowFast network is used to generate motion and environmental information feature maps from the video. Then, the spatio-temporal attention module is applied to the feature maps, including information aggregation, compression and stimulation processes. Subsequently, attention maps in the time, channel and space dimensions are obtained, and multi-label behavior classification is performed based on these attention maps. To solve the long-tail data problem that exists in student classroom behavior datasets, we use an improved focal loss function to assign more weight to the tail class data during training. Experimental results are conducted on a self-made student classroom behavior dataset named STSCB. Compared with the SlowFast model, the average accuracy of student behavior classification detection improves by 8.94\% using BDSTA.

    Abstract: Awe is a profound, self-transcendent emotion. To illuminate its origin, four preregistered studies examined how U.S. 4- to 9-year-old children perceive awe-inspiring stimuli (N = 444, 55% female, 58% White, tested in 2020-2023). Awe-inspiring expansive ... ...

    Abstract Awe is a profound, self-transcendent emotion. To illuminate its origin, four preregistered studies examined how U.S. 4- to 9-year-old children perceive awe-inspiring stimuli (N = 444, 55% female, 58% White, tested in 2020-2023). Awe-inspiring expansive nature (Study 1) and natural disaster scenes (Study 2) evoked perceived vastness, motivation to explore, and awareness of the unknown more than everyday scenes did (d ranging 0.32-1.76). Compared to expansive social stimuli, expansive nature stimuli more positively affected children's sense of self (Study 3). Diverse awe-inspiring scenes (vast nature, natural disasters, and slow-motion objects) all elicited awe and higher learning motivation than everyday scenes did (Study 4). These findings suggest that children appreciate awe-inspiring visual experiences, illuminating the origins and nature of awe as a self-transcendent experience.
