    Abstract This article draws on Bayat’s discussions of the “quiet encroachment” and “social nonmovement” to explore the intertwined relationships between mundane lives, public culture, and spatial orders. It takes the collective singing practices in public parks in the city of Guangzhou in South China as a case study, and at the center of analysis are senior urban residents who have experienced double marginalization under the new political economy and the new spatial order in public spaces. I show that collective singing in parks, which is a cultivated practice acting upon a body’s habitus shaped by the political culture, has contributed to rebuild the social life of the senior citizens after layoffs. While such an embodied practice has been re-appropriated by the government and officials to capitalize on the authority of political culture to further their ends, such re-appropriation also empowers the choral participants to pursue happiness in their familiar ways and legitimize their claims on public spaces that are increasingly coded with a middle-class civility. I argue that the analytical lens offered by “social nonmovement” helps shift attention from agency to action. By focusing on how effects of state-orchestrated governing strategies have been made complicated by ordinary people’s “quiet encroachment”, this article shows that the exercise and effects of power shall be analyzed as a dynamic process with a spatial and temporal dimension. The exploration of the layers of social, political and visceral experiences between individual citizens and the social-political space can effectively help us diagnose how power works and morphs.

    A Simultaneous Equation Approach

    2021  Volume 7673

    Abstract Purpose: This study investigates the bidirectional relationship between body weight and depression for both males and females in the U.S. Methods: Data are drawn from the 2019 Behavioral Risk Factor Surveillance System (BRFSS), and a simultaneous ordered probability system is estimated with maximum likelihood estimation (MLE) to accommodate the two-way causality between depression and body weight categories. The variable of depression is measured by individuals’ past depressive records and current mental health status. Results: Depression and body weight are found to affect each other positively for both males and females on average. In a randomized population, the results of average treatment effects suggest significant body weight differences between depressed and non-depressed individuals. Age and other sociodemographic factors affect body weight differently between genders and between the people with depression and those without. Conclusion: The positive bidirectional relationship between body weight and depression is found. The effect of depression on body weight is significant among both males and females in a randomized population, and females who experience depression are most likely to be obese and less likely to have normal weight compared to females without depression. The risks of overweight and obesity are high among people who are less educated or unable, who have poor health statuses, and who had high blood pressure.

    Abstract Effect size is a statistical concept which measures the strength of the relationship between two variables. Effect size has basic properties such as measurement unit independence, sample size independence, and monotonicity. In particular, unlike statistical significance test, effect size is not influenced by sample size. Effect size avoids various problems in statistical significance tests. It is one of the important contents in constructing new statistics. In present study, various effect sizes were mathematically described and a free desktop calculator for effect sizes was presented.

    Abstract The t-test theory has laid the foundation of modern statistics and it is one of the main contents of statistics. This theory can be found in all statistics textbooks and is at the core of almost all applied statistics courses. At the same time, almost all statistical software or tools have t-test content, such as Matlab, SAS, SPSS, R, etc. However, t-test theory has been widely criticized in recent years due to its theoretical flaws and misuse. The t-test is only used for the problems of normal distribution population with small sample size. Even so, its sample size cannot be too small due to problems such as t-transformation distortion. In terms of significance test, the t-test has the general defects of statistical significance tests, coupled with the inherent fallacies of confidence intervals, and the peculiar uncertainty problems of t-intervals, make the t-test methodology obviously insufficient. The t-test theory is faced with the retaining or discarding decision in statistics, and some statisticians have advocated and abolished the t-test theory from statistics textbooks. As a statistical significance test, the solutions of t-tests include using Bayesian methods, performing meta-analyses, using effect sizes, stressing statistical validity, using nonparametric statistics, using good experimental and sampling designs and determining appropriate sample size, the network methods are used instead of the reductionist method to obtain and analyze the data, and the statistical conclusions are combined with the mechanism analysis to draw scientific inferences, etc. As a t-interval uncertainty problem, its solutions include using the Bayesian credible interval method, using the Bootstrap credible interval method, inferring directly from the central limit theorem, using the unified theory of uncertainty, etc.

    Abstract To explore the influence of campus public space characteristics on students’ emotions, we investigated the association mechanism between public space characteristics and students’ emotions concerning the distribution of students’ emotions in public spaces. The present study used photographs of facial expressions taken over two consecutive weeks as a source of data regarding the students’ affective reactions. The collected facial expression images were analyzed using facial expression recognition. Values were assigned to the expression data, combined with geographic coordinates to create an emotion map of the campus public space using GIS software. Then, spatial feature data via emotion marker points were collected. We used smart wearable devices to combine the ECG data with spatial characteristics and took SDNN and RMSSD as ECG indicators to assess mood changes. We analyzed the correlation between these spatial features and heart rate variability and developed regression models for the ECG data. The findings show that sky visibility, space D/H, green visibility, skyline change index, and boundary permeability can engage students’ positive emotions in a meaningful way. On the other hand, paving visibility and road linearity tends to induce negative emotions in students’ minds.

    Abstract IntroductionIn sports competitions, using energy-saving and emission-reduction measures is an important means to achieve the carbon neutrality goal.MethodsIn this paper, we propose an attention mechanism-based convolutional neural network (CNN) combined with the gated recurrent unit (GRU) for carbon neutral energy saving and emission reduction prediction model in sports competitions, CNN is a feedforward neural network whose input is a two-dimensional matrix. The main feature of CNN is that it can handle multi-channel input data, and the use of GRU can make the model structure simple and largely reduce The use of GRU can make the model structure simple, which largely reduces the hardware computational power and time cost and also better solves the long dependency problem in RNN networks. CNN-GRU extracts the data for features and then optimized by the attention mechanism.ResultsThe model collects real-time carbon emissions data from sports events, including game times, lighting usage, air conditioning emissions and other carbon emissions data, and uses deep learning algorithms to predict and compare carbon emissions from sports competition.DiscussionIn identifying energy saving and emission reduction measures conducive to the realization of the goal of carbon neutral sports events, the model has a certain reference value for realizing energy saving and emission reduction in sports competitions under carbon neutrality goals.

    Abstract Teachers' online professional development (PD) has been valued as a crucial and effective way to promote teaching competencies. Forming a professional learning community has been recognized as a means to promote effective PD. Within this realm of research, the Community of Inquiry (CoI) framework was deemed as a collaborative-constructivist process model that describes successful online learning experiences. The CoI has been associated with many psychological and educational variables, such as learning achievement and self-efficacy. This study leveraged on the CoI framework to assess teachers' online professional learning quality and explored its relationship with their self-efficacy and online professional learning achievement. A total of 456 teacher participants from Chinese middle schools participated in our study. A suite of questionnaires (the Community of Inquiry Questionnaire, the Teacher Efficacy Scale, and the Perceived Online Learning Achievement Scale) was distributed. Linear regression, PROCESS Macro mediation, and moderation analyses were run on the data to answer the research questions. Results revealed a significant relationship between teachers’ online learning quality and their self-efficacy and learning achievement. The mediating roles of self-efficacy and learning achievement were confirmed. The moderating role of time spent on receiving online professional learning was also recognized. Implications and future directions were discussed.

    Abstract In the realm of pharmaceutical advancement, the transformative prowess of nanotechnology shines through its precision-targeted drug delivery and amplified therapeutic effects. This paper ventures into the realm of radiolabeling techniques for unraveling the intricate choreography of drug kinetics within the bloodstream which encompass the delicate stages of absorption, distribution, metabolism, and excretion. Through the magical lens of the radiolabel, a real-time spectacle unfolds, providing invaluable insights into the safety and efficacy of nanomedicine interventions. Amid the labyrinthine complexities of drug-organism interactions and the lack of universal protocols for nanomedicine preparation, radiolabeling technology has emerged as a guiding constellation. The paper systematically assesses the methods commonly employed for pharmacokinetic studies, delves into the manifold advantages and techniques of radiolabel methods within the nanomedicine landscape, closely examines their application across a spectrum of pharmacokinetic studies and thoughtfully addresses the challenges they may pose. Embark on this illuminating odyssey—a journey that peers into the microcosm of nanomedicine, deciphering its dynamic interplay within the bloodstream through the luminary insights of radiolabeled tracing techniques.
