摘要:
Physical activity performed in a natural environment, especially among green spaces, is associated with mental health benefits. Yet few studies have explored the separable influences of visual perception on the effects of green exercise. The present study assessed the extent to which two components of visual perception (form and color) contributed to mental health benefits by separating the form and color characteristics of an image of a green tree. In total, 76 healthy college students (18–24 years of age) engaged in incremental cycling exercise at a moderate intensity while viewing an image in front of them on a large screen. Participants were randomly assigned to one of four groups in which the image they viewed was a green tree, an achromatic tree, a formless color green, or a formless achromatic color. Before and after cycling (test time), participants’ selective attention, mood state, and self-esteem were assessed using the Perception and Attention Function battery and the Chinese versions of the Profile of Mood States scale and the Rosenberg Self-Esteem Scale, respectively. Significant interactions detected between test time and form perception indicated that scores in total mood disturbance decreased and scores in the esteem subscale and self-esteem scale increased after cycling while viewing trees. A significant interaction between test time and color perception indicated that anger decreased in the two green color conditions. A significant interaction of color perception by form perception by test time was associated with a significant decrease in response times on the attention task after cycling among participants who viewed the green tree. Our findings are important for interpreting mechanisms underlying characteristics attributable to environmental benefits and revealed that single (color or form) or combined (color and form) visual perception improved the mental health benefits of exercise. These findings may also inform the design and planning of urban green spaces to maximize green exercise effects.
摘要:
Development in science, technology, engineering, and mathematics (STEM) is widely emphasized worldwide. In the past decades, China has become the largest rising economy with a strong forward momentum in STEM advancement and education, which has profoundly impacted the global economy. This study investigates the current trends in STEM career aspirations among Chinese adolescents, who will soon become the future workforce. The results indicate a significant increase of students' STEM aspirations in comparison to the 2015 PISA outcomes. Further investigation suggests that the rapid change can be attributed to the recent transitions in world politics which have shifted from collaboration to exclusive competition. Insights gained from this study call for a change of mindset to recognize that in the STEM economy, collaboration is the most powerful form of competition.

摘要:
Following preventive behaviors is a key measure to protect people from infectious diseases. Protection motivation theory (PMT) suggests that perceived risk motivates individuals to take protective measures. The COVID-19 pandemic has posed unprecedented stress to the public, and changes in perceived risk may be more pronounced among college students than among other groups due to the related campus lockdown. With 1,119 college students recruited as research subjects, a quantitative research was conducted in Wuhan, China, to deduce the relationship between the perceived risk and preventive behavior of college students, as well as between the mediation effect of individual affect and the moderating effect of physical exercise. The results showed that the preventive behavior of college students was significantly affected by perceived risk, and both positive affect and negative affect played a mediating role between perceived risk and preventive behavior. Specifically, positive affect aided the relationship between perceived risk and preventive behavior, negative affect was detrimental to their relationship, and the mediation effect of positive affect is significantly higher than that of negative affect. Furthermore, physical exercise played a moderating role in the mediation effects of positive affect and negative affect. Therefore, appropriate measures should be taken to strengthen Chinese college students' perceived risk and provide them with corresponding guidance. The importance of physical exercise should also be emphasized to help college students with low perceived risk reduce negative affect, increase positive affect, and promote their preventive behavior.
摘要:
Previous studies have implied that physical activity profoundly influences interpersonal adaptation. However, this effect and its mechanisms have not been directly verified, especially for adolescents. This study examines the association between physical activity and interpersonal adaptation in adolescents through self-esteem and psychological resilience after the coronavirus disease 2019 (COVID-19) pandemic. Participants included 542 Chinese adolescents (aged 13-18 years; 242 boys and 300 girls). Adolescents in China anonymously completed a series of questionnaires, including the PARS-3 Scale of PE Activity Grade (PARS-3), the Self-esteem Scale (SES), the Resilience Scale for Adolescents (RSCA), and the Interpersonal Adaptation Scale. The results showed that physical activity positively correlated with self-esteem, psychological resilience, and interpersonal adaptation. Additionally, self-esteem and psychological resilience serially mediated the impact of physical activity on interpersonal adaptation. The findings highlight the positive impact of physical activity on adolescent interpersonal adaptation by strengthening positive psychological resources in the post-pandemic era.

摘要:
Abstract: Regarding the association between sleep and napping duration and mental health in young and older adults, some studies indicated a positive association, while others indicated a negative, or no, association between them. Moreover, collegiate student athletes have different mental health stressors, such as training pressure, improving sports performance, and relationships with coaches. Therefore, sleep is important for athletes. Whether sleep duration is related to their mental health is unclear. Thus, this study aimed to examine the association between nighttime sleep duration, daytime napping duration, and mental health among collegiate student athletees. This cross-sectional study included 700 college athletes. Sleep and daytime napping durations were assessed using a self-reported questionnaire. The Zung Self-rating Depression Scale and Generalized Anxiety Disorder-7 assessed mental health. A multivariate logistic regression analysis was conducted to examine the adjusted association between sleep duration and mental health. In this study, the odds ratios for depression and anxiety symptoms were significantly higher for short sleep duration (<7 h). Additionally, a significant positive association was found between daytime napping duration and the prevalence of depression. This study indicates that short nighttime sleep and long daytime napping duration may be risk factors for collegiate student athletes’ mental health, having important implications for educators and coaches.

摘要:
National security has become a significant force in the current state. In war, a strategy is the basic unit of defense in any country. There are many concerns about these personnel fighters' fitness using smart sensors to be familiar with GPS (Global Positioning System). Used to solve and log in range, of GPS bearer can get to know well without any problems. The worker at the base station will give an association using a single worker telecommunication system. Each cavalry has a GSMC (Global System Mobile Communications) module for the base station during injury and disaster, and its recognition applies. During the war that put forward the concept of component, soldiers are now a GPS lighthouse-like soldier's updated state. As the discovery progressed, images were taken to monitor the human body's physiological boundaries from various wearable senses. Such physiological and biomedical sensor centers can use the Body Sensor Network (BSN), close to or inside the human body, for periodic welfare surveys. Will design a series of efforts to establish a framework for field studies of relentless welfare fighters, including BSNs. Talk about the basics of this joint venture application. Propose an application that affects the initial model characterization and source boundary of the framework. A high mental quality employee should have an average product volume (P <0.05) of 66% higher than the average of low mental quality players. The ‘administrative law enforcement’ for military veterans are between real arrangements in different areas.

摘要:
Which statistical features distinguish a meaningful text (possibly written in an unknown system) from a meaningless set of symbols? Here we answer this question by comparing features of the first half of a text to its second half. This comparison can uncover hidden effects, because the halves have the same values of many parameters (style, genre, etc). We found that the first half has more different words and more rare words than the second half. Also, words in the first half are distributed less homogeneously over the text. These differences hold for the significant majority of several hundred relatively short texts we studied. Differences disappear after a random permutation of words that destroys the linear structure of the text. The differences reveal a temporal asymmetry in meaningful texts, which is confirmed by showing that texts are much better compressible in their natural way (i.e. along the narrative) than in the word-inverted form. We conjecture that these results connect the semantic organization of a text (defined by the flow of its narrative) to its statistical features.

摘要:
Research on chronic traumatic encephalopathy (CTE) has increased over the past two decades. However, few studies have statistically analyzed these publications. In this work, we conducted a bibliometric analysis of studies on CTE to track research trends and highlight current research hotspots. Relevant original articles were obtained from the Web of Science Core Collection database between 1999 and 2019. CiteSpace and VOSviewer software were used to perform analysis and visualization of scientific productivity and emerging trends. Our results show that the publications related to CTE dramatically increased from four publications in 1999 to 160 publications in 2019. The United States dominated this field with 732 publications (75.934%), followed by Canada with 88 publications (9.129%). Most of related publications were published in the journals with a focus on molecular biology, immunology, neurology, sports and ophthalmology, as represented by the dual-map overlay. A total of 11 major clusters were explored based on the reference co-citation analysis. In addition, three predominant research topics were summarized by clustering high-frequency keywords: epidemiological, clinical and pathological studies. The research frontiers were the diagnosis of diseases using new neuroimaging techniques, and the investigation of the molecular mechanism of tau aggregation. This study provides researchers with valuable guidance in the selection of research topics.

摘要:
This study applied self-determination theory to examine Chinese college women motivational profiles and their association with physical activity involvement, health-related quality of life, and physical fitness. 292 Chinese college women completed questionnaires assessing relevant psychological constructs and physical activity involvement. Their physical fitness was measured based on the China National Fitness Test Program including body shape, pulmonary function, and body fitness. A two-step cluster analysis determined the profiles that resulted from the interactions among motivation variables reflecting the degree of self-determination. Four distinct clusters of college women were identified: low self-determination/high control, low combination, high combination, and high self-determination/low control. There were significant differences among the clusters in physical activity involvement (p < .01, eta(2) = .11), health-related quality of life (p < .01, eta(2) = .18), and physical fitness (p < .01, eta(2) = .04). Findings support the importance of developing self-determination in Chinese college women' physical activity, fitness and health-related quality of life.
摘要:
This study builds an evaluation model of national fossil-energy carbon footprints based on regional average net primary productivity calculated by weighted method and evaluates the carbon footprint of fossil fuel energy consist of oil, natural gas and coal for 64 major carbon emitters, on the basis of regional net primary productivity data of various land types and national fossil fuel energy consumption data. The variation of national total and per capita fossil-energy carbon footprints is analyzed and compared, and global overall changes of nonuniform distribution of national fossil-energy carbon footprints are analyzed via application of the gravity model, which provides a methodology to present the trend of overall changes of a certain attribute in the non-uniform geographical distribution problem. The target years for calculation and analysis of fossil-energy carbon footprints are from 1997 to 2016. The results show that the majority of developed countries present decrease while most of developing countries present increase both in the total and per capita fossil-energy carbon footprint during the twenty years, and serious polarization is found in the rankings of the twenty-year average of both total and per capita fossil-energy carbon footprint, with the maximum value being respectively 486 and 583 times of the minimum value. And both the global total and per capita fossil-energy carbon footprint barycenter, which are introduced according to the gravity model, generally move toward southeast during 1997 -2016 with different change range, proving an uneven growth of the fossil-energy carbon footprints worldwide. And the global distribution of fossil-energy carbon footprints has become more nonuniform in value. Several policy recommendations are proposed on the aspects of carbon emission reduction and promotion of carbon absorption from productive lands, and all the countries are emphasized with equal responsibility of carbon footprint reduction.

摘要:
Several recent studies revealed that physical activity programs that focus on fundamental motor skills could enhance both motor and social performance. The purpose of this pilot was to explore whether the social impairment of Autistic Spectrum Disorders (ASD) moderated the motor outcomes of a physical activity program. Nine children with ASD attended a 2-week program that adopted the Classroom Pivotal Response Teaching. Significant improvements on motor skills were found in all participants. Furthermore, children with more social impairment demonstrated greater motor improvement in comparison to those with less social problems. Findings suggest the importance of social factors on the outcomes of physical activity programs and the interplays between social and motor domains in ASD interventions.
摘要:
Financial networks have become extremely useful in characterizing the structures of complex financial systems. Meanwhile, the time evolution property of the stock markets can be described by temporal networks. We utilize the temporal network framework to characterize the time-evolving correlation-based networks of stock markets. The market instability can be detected by the evolution of the topology structure of the financial networks. We then employ the temporal centrality as a portfolio selection tool. Those portfolios, which are composed of peripheral stocks with low temporal centrality scores, have consistently better performance under different portfolio optimization frameworks, suggesting that the temporal centrality measure can be used as new portfolio optimization and risk management tool. Our results reveal the importance of the temporal attributes of the stock markets, which should be taken serious consideration in real life applications. (C) 2018 Elsevier B.V. All rights reserved.
