Abstract： Humans are a social species that are constantly involved in complex relationships, reacting to the actions of others, and intentionally or unintentionally changing our own behavior. Personality traits reflect the behavioral pattern of an individual's response to the environment, which also includes social behavior. In addition, the brain is also an important factor when discussing social networks. The brain provides biological mechanisms for human behavior, while social networks provide external triggers for these behaviors. Linking personality traits and brain activity to social networks can help us better understand the structure of group relationships, improve our understanding of individual human beings, and help us better predict individual social behaviors and find the rules of information transmission in interpersonal relationships. From the perspective of a network, we collected nine social networks from 94 undergraduate students in the same grade according to their different social needs. We used the graph theory and resting-state functional magnetic resonance imaging to explore the influence of personality traits on social networks based on individual popularity and closeness between individuals and the relationship between the similarity of brain resting-state functional connectivity and social distance between individuals. Specifically, regression analysis was carried out, with personality traits as the independent variables and the different degrees of social networks as the dependent variables. Then, a correlation analysis was performed for the social distance and similarity of personality traits. Finally, the correlation between the similarity of the brain networks and social distance was calculated. The results showed that (1) individuals with high conscientiousness were more popular in social networks requiring "trust" traits, while individuals with high agreeableness were more popular in social networks requiring "fun" traits. These findings showed that in the same group, there are different social networks according to social needs, and the popularity of individuals in different social networks is not similar as it will be affected by the corresponding personality traits; (2) In the social networks requiring "shared interests & values, " personality similarity and social distance between individuals were significantly negatively correlated. Personality similarity promotes interpersonal communication between individuals, which may be realized through interpersonal attraction induced by the similarity of values and interests; (3) In the same social network, there is a significantly negative correlation between similarities in functional connections (FCs) and social distance among individuals, and these FCs are mainly concentrated in the fronto-parietal task control network and the dorsal attention network. The similarity of resting brain FCs among individuals may promote interpersonal communication, possibly due to the similarity of individuals in cognitive control and environmental processing bias, which increases the interpersonal attraction and shortening the social distance between individuals. The results revealed the influence of personality traits on the structure of different social networks, the relationship between personality trait similarity among individuals, and the similarity between resting brain networks and social distance, which has important implications for understanding the structure of social networks, the formation rules, and the information transmission rules among them. In addition, this study discussed the relationship between the similarity of resting-state FC and social distance, providing new evidence for studies on brain synchronization in interpersonal communication and brain imaging evidence for the study of the relationship between the similarity of personality traits and social distance.#social networks, personality traits, resting-state functional connectivity

Abstract： Meta-analysis is a crucial tool for accumulating evidence in basic and applied research. In the open science era, meta-analysis becomes an important way for integrating open data from different sources. Meanwhile, because of the great researchers’ degree introduced by multiple-step and multiple-choices in each step of meta-analysis, the openness and transparency are crucial for reproducing results of meta-analysis. To (1) understand the transparency and openness of meta-analysis reports published in Chinese journals and (2) improve the transparency and openness of future meta-analysis by Chinese researchers, we developed a Chinese version of checklist for meta-analysis, which was based on the Preferred Reporting Items for Systematic Review and Meta-Analysis protocols (PRISMA) and the principle of openness and transparency, and then surveyed the methods and results of 68 meta-analysis papers in mainstream Chinese psychological journals in last five years. Our results revealed that openness and transparency of Chinese meta-analysis reports need to be improved, especially in the following aspects: the date/time and limitation of literature search, the details of screening and data collection, the flow chart of article screening, the details of effect size transformation, and the evaluation of individual research bias. The checklist we present, which lists almost all aspects that an open meta-analysis should include, can be used as a guide for future meta-analysis.

Abstract：传统光学天象厅因为节目制作难度大，成本高昂，功能扩展困难等缺点逐渐被功能强大的数字天象厅取代。随着天文教育和科普的深入推广，国内对数字天象厅的需求越来越大。数字天象厅的核心是球幕投影技术。针对球幕投影技术存在的一些技术问题，如自动化程度不高，需要人工干预等，提出了面向中小型球幕天象厅易于实现的多投影自动拼接方案。对方案中的几何校正、亮度校正、颜色校正等核心功能进行了详细的论述。该方案便于操作，易于实现，对中小型球幕有良好表现，对大型球幕也有借鉴意义。
