Abstract： Returnees usually face problems of re-adaptation when returning to their home country after living abroad for a period of time. One of the significant issues is the reverse culture shock. This latter may have severe consequential impacts on returnee’s mental health, emotional stress, interpersonal relationships and sociocultural adaptation. Our current work sorts out the psychological and behavioral consequences of the reverse cultural shock, and analyzes the conceptual framework and its underlying mental processes. It is our hope that this work would provide scientific evidence and empirical support to better inform the government and higher education institutions regarding policy making. "

Abstract：磁场是太阳爆发活动的根本驱动力，高精度实时偏振测量是实现磁场测量的常用方法。然而常用的波片式测量方法需要进行多次测量，且存在机械旋转结构，易导致仪器抖动，降低测量精度；波片旋转或切入切出也会导致测量时间较长。目前，基于DKDP晶体和波片的太阳大气偏振测量周期较长，实时性不高，无法应用于快速变化的太阳活动磁场探测。基于以上背景，本论文提出了一种基于双DKDP晶体原理的太阳大气实时偏振探测技术，采用两片快轴方向不同的DKDP晶体，通过外加不同电压进行快速相位延迟变化，实现对入射太阳光的偏振调制，获取太阳大气偏振斯托克斯矢量。相较于传统旋转波片与DKDP晶体相结合的方法，本论文提出方法可将单次偏振调制速率从数秒提升到毫秒级，极大地提升了太阳磁场测量实时性。仿真分析结果表明：本文提出方法测量精度达到2×〖10〗^(-3)，单波长点测量时间分辨率提升了20倍以上，可以实现对太阳磁场偏振信息的实时精确测量。

Abstract：为了研究乌海市沿黄河两岸沙丘风沙流结构差异与冰面风沙特征，开展以黄河西岸-黄河冰面-黄河东岸为路径的风沙观测实验，通过对比分析黄河两岸沙丘风沙流结构、沙尘粒度特征，为黄河沙尘防控问题提供理论依据。研究表明： 两岸沙丘总输沙率均随着高度增加而减小，东岸输沙率垂直拟合优度较西岸差，风沙流比西岸更容易达到非饱和状态。 黄河冰面裂缝滞留沙尘粒径大于0.19 mm，较小颗粒则输移到东岸，东岸沙丘受矿采区粉尘影响，极细砂粒（0.05~0.1 mm）含量增加，极细砂平均含量东岸<西岸，沙尘平均粒径东岸<西岸。 沿黄河两岸沙丘与冰面沙尘的粒度参数峰度均为宽峰态，沙物质来源相似。

Abstract： Researchers paid more attention to the role of leadership negative behavior. Recently, researchers have begun to concern the effect of leaders’ emotions on employees in organizations. In the organization, employees are highly dependent on leaders and are more susceptible to leaders’ emotions. Emotion As Social Information (EASI) describes interpersonal effects of emotions on behavior in the interpersonal interactions. Emotional expressions affect observers’ behavior by triggering their inferential processes and/or affective reactions. The predictive strength of these two processes depends on observer’s information processing and social-relational factors. Based on this, we proposed that leader’s negative emotional displays triggers employees’ negative emotional experiences and reduce their work engagement. Motivational orientation theory states that employees process positive or negative stimuli that closely related to their jobs. Thereby these stimuli triggers employees’ goal orientation including of mastery goal orientation, performance-avoid goal orientation, performance-prove goal orientation. Based on this, we proposed that leader’s negative emotional displays have negative impacts on employee’s mastery goal orientation and performance-prove goal orientation, a positive impact on employee’s avoid goal orientation. Based on previous studies, we proposed that employee's goal orientation further predicts his or her work engagement. In summary, we proposed that goal orientation mediate the relationship between leader’s negative emotional displays and employee’s work engagement. Leader’s negative emotional displays, employee’s goal orientation and work engagement have state-like properties, varying in different environment. Thus, this study used Empirical Sampling Method (ESM) to explore the relationships between them. Within 5 work days, employees evaluated their leader’s negative emotional displays and goal orientation of themselves at 10:30 am; at 16:00, and the leaders evaluated their employee's work engagement. At last, we got 496 matching questionnaires of 109 employees and 24 leaders. The survey started from Monday to Friday, all the leaders distributed the numbered paper questionnaire to the employees, and the researchers collected it back after half an hour. They checked them and exclude the unqualified questionnaire which chose totally same options. We examined leader’s negative emotional displays and goal orientation at both interindividual(between-person level) and intraindividual (within-person) levels. To find the relationships between leader’s negative emotional displays, goal orientation and work engagement at between –person level and within-person level. This study reached the following conclusions: At within-person level, (1) Leader’s negative emotional displays in the morning have significant negative effects on employee’s mastery goal orientation and performance-prove goal orientation, while it has significant positive effect on performance-avoid goal orientation. And mastery goal orientation and performance-prove goal orientation have significant positive effects on employees’ work engagement, while performance-avoid goal orientation has a significant positive effect on it. Moreover, mastery goal orientation, performance-avoid goal orientation and performance-prove goal orientation play mediating roles between leader’s negative emotional displays and employees’ work engagement. At between-person level，(2) Leader’s negative emotional displays have significant negative effects on mastery goal orientation and performance-prove goal orientation, while it has a significant positive effect on performance avoid orientation in the afternoon. And mastery goal orientation and performance-prove goal orientation have significant positive effects on employees’ work engagement, while performance-avoid goal orientation hasn’t a significant positive effect on it.. Moreover mastery goal orientation and performance-prove goal orientation play mediating roles between leader’s negative emotional displays and employee engagement. The result showed that the relationships “leader’s negative emotional displays – avoid goal orientation – work engagement” at the between-person level differ significantly from the respective relationships at the within person level. This suggested that processes are emergent. Through collecting day-level data by empirical sampling method and using multi-layer model, this study found that: First, the “emergence” effect or environmental effect. The relationship of state performance-avoid goal orientation emerged only at the within-person level of analysis. Second, leader’s negative emotional displays is an independent concept rather than a clue embedded in some kind of leader’s behavior in this study. We get more comprehensive understanding of the impact of leader’s negative emotional displays on employees’ goal motivation and work engagement. Through goal orientation, leader negative still plays affect on employees’ work engagement. Third, this study showed the impact of leadership emotions on employees from an interactive perspective. These results of this study have important management implications for managerial settings. They call our attention to improve the awareness of leader’s negative emotion management. When leaders interact with employees, leaders need to be aware that their emotions have a significant impact on employees’ goal orientation and work engagement especially when they want to decrease the performance-avoid goal orientation in the daily work.

Abstract： In sensor network topology environment with uneven node distribution, running the DV-Hop localization algorithm often causes large errors of hop value. Considering the problem above, this paper proposed an improved localization algorithm named ILDV-Hop. Firstly, for the whole network, this algorithm calculated an effective hop size based on difference of actual and estimated distance between reference nodes. Then, with adding a correction value to the hops between unknown nodes and reference nodes, it also used the received signal strength indicator (RSSI) value to correct the distance of a single hop. Finally, the Levenberg–Marquardt algorithm was applied to estimate an optimize position for each sensor. Simulation results indicate that, compared with the DV-Hop algorithm and the DV-Hop algorithm based on Quasi-Newton, the ILDV-Hop algorithm has reduced the errors by about 23% and 10% respectively, and the localization performance has increased visibly.
