Abstract： Trust is the basis of successful human-robot interaction. However, humans do not always hold the appropriate level of trust in human-robot interaction, sometimes they may also fall into pitfalls: the trust bias, which contains both over-trust and under-trust. Trust bias can harm the human-robot interaction and so trust calibration is necessary. Trust calibration is often achieved through two ways: trust dampening and trust promoting. Trust dampening focuses on how to reduce the high level of trust in robots, while trust promoting focuses on how to improve the low level of trust in robots. For future directions, we suggest further optimize the measurement of methods. Besides, we also need to clarify the cognitive process and explore more boundary conditions. Finally, in order to boost human-robot collaboration, researchers are encouraged to explore personalized and specialized trust calibration strategies based on individual differences and further clarify the various reasons why trust bias occurs.

Abstract： Fast radio bursts (FRBs) are extra-galactic origin milli-second duration bright radio bursts. Theoretically, FRBs may produce optical counterparts with durations from milliseconds to hours. The FRB optical counterparts may be detectable in future large field telescopes in China, including the China Space Station Survey Space Telescope (CSST), the 2.5-meter Large Field Survey Telescope (WFST) of the University of Science and Technology of China (USTC), and the Purple Mountain Observatory (PMO), and Earth 2.0 (ET). The fast radio burst optical counterparts are grouped into millisecond time-scale optical counterparts, hourly time-scale optical counterparts, and optical afterglow for our study. The first two can be generated by the high-energy extension of FRBs or the radio radiation of fast radio bursts and the inverse Compton scattering of high-energy electrons. The event rates highly depend on the optical-radio flux ratio $\eta_{\rm \nu}$. For millisecond duration optical counterparts, the detection rate of WFST, CSST, and ET can reach hundreds per year in an ideal case. If $\eta_{\rm \nu} \sim 10^{-3}$, the corresponding annual detection rates of WFST and CSST are in the order of 1, and the annual detection rate of ET is 19.5. For the hourly optical counterparts, ideally, the age of the supernova remnant is 5 years, $\eta_{\nu}$ is about 10$^{-6}$, and the annual detection rates are above 100. The X-ray counterpart of FRB 200428 indicates that FRBs may produce relativistic outflow, which will interact with the interstellar medium to produce optical afterglows. Combined with the standard afterglow model, the detectability of optical afterglow is explored with a simulation of fast radio bursts following the redshift and energy distribution from the literature. With a total energy-radio energy ratio similar to FRB 200428, $\zeta=10^5$, the estimated annual detection rates of CSST, WFST, and ET are 1.3, 1.0, and 67, respectively.

Abstract： Collective narcissism is the group-level equivalent of individual narcissism and is currently defined as the belief that one's own group is exceptional and entitled to privileged treatment but it is not sufficiently recognized by others. Current research findings show that it has relatively strong explanatory power for intergroup hostility, because collective narcissists are hypersensitive to threats to their in-group image, status, or identity, and are prone to overestimate threats and suspect out-groups; and that lacking sense of self-worth and personal control is one important source of collective narcissism. After reviewing the past research on collective narcissism, combined with latest progress in the field of individual narcissism, this paper proposes several important questions that remain to be investigated in the field of collective narcissism. First, does collective narcissism necessarily entail vulnerability? Currently, collective narcissism tends to be understood as collective self-esteem that is contingent on admiration and recognition from others. This suggests that collective narcissists are generally conceived to be fragile internally, in that it is because of the vulnerability implicit in their own beliefs—or in other words, their own lack of confidence in their in-group's exceptional image—that they are prone to demand external affirmation or recognition. However, vulnerability may not be a necessary attribute of collective narcissism because there may be collective narcissism that is not fragile, just as there may be individual narcissism that is not fragile. Therefore, researchers may consider appropriately narrowing the connotation of collective narcissism to expand its denotation so as to explore more diverse forms of collective narcissism, such as collective narcissism with and without vulnerability. Second, is the structure of collective narcissism one-dimensional? If not, what dimensions does it have? Although the most widely used collective narcissism scale has a one-dimensional structure, recent studies have developed and validated collective narcissism scales with a multidimensional structure. These studies are preliminary, however, and only suggest it is necessary to carry out multidimensional exploration. As for the exact structure of collective narcissism, further exploration is needed. And future research should not only explore the dimensions of collective narcissism, but also explore the sub-dimensions of both of vulnerable collective narcissism and grandiose collective narcissism. Third, are the consequences of collective narcissism always negative? The vast majority of current research has focused on revealing the negative effects of collective narcissism, and very few studies have directly examined and found positive effects of collective narcissism. However, according to E. Fromm's classical theoretical view, collective narcissism may also have its benign forms within certain limits, just as individual narcissism may also have an adaptive side. Therefore, future research should explore the effects of collective narcissism from a more complete theoretical perspective, and especially, examine more the positive effects of collective narcissism. Finally, does collective narcissism stem simply from frustrated individual needs? Although studies in recent years have begun to investigate the causes of collective narcissism, these studies largely focus on individual motivational factors and fail to examine them together with factors such as cognitions and sociocultural contexts. Future research may draw on ideas from theories such as system justification theory, social identity theory, and self-categorization theory to explore a more complete explanation for the phenomenon of collective narcissism. In summary, after more than a decade of research, there are still many theoretically meaningful questions in the field of collective narcissism that deserve further exploration. And in today's world, such exploration also has profound practical significance, and it may bring a wealth of insights into how to deal with the struggles of various social groups for recognition.

Abstract：
Collective narcissism is the group-level equivalent of individual narcissism and is currently defined as the belief that one’s own group is exceptional and entitled to privileged treatment but it is not sufficiently recognized by others. Current research findings show that it has relatively strong explanatory power for intergroup hostility, because collective narcissists are hypersensitive to threats to their in-group image, status, or identity, and are prone to overestimate threats and suspect out-groups; and that lacking sense of self-worth and personal control is one important source of collective narcissism. Although collective narcissism is preconceived in current research as fragile and negative, its attributes are not necessarily so. Thus, future studies on it should first clarify its concept and structure; then, continue to explore its negative and positive consequences, its multiple causes and interventions; and in the meantime, advance cross-cultural research.

Abstract： To improve the efficiency of automatic container port equipment. This paper proposes a new container import and export technology, namely yard - yard crane - AGV partner - AGV - quay crane. On the basis of considering the buffer capacity limit, an AGV scheduling mixed integer programming model with time window constraint was built. A heuristic algorithm was designed to solve the AGV partner’s time window and the model was solved by PSO algorithm , and presents a corresponding scheduling optimization scheme. The experiment results show that the setting of the AGV partner can effectively improve the coordination between AGV and yard crane and reduce the waiting time between the equipment. When the AGV partner capacity is certain , the waiting time of the yard crane decreases with the increase of AGV.
