The spatial and temporal distribution of tunnel failure is very complex due to geologic heterogeneity and variability in both mining processes and tunnel arrangement in deep metal mines. In this paper, the quantitative risk assessment for deep tunnel failure was performed using a normal cloud model at the Ashele copper mine, China. This was completed by considering the evaluation indexes of geological condition, mining process, and microseismic data. A weighted distribution of evaluation indexes was determined by implementation of an entropy weight method to reveal the primary parameters controlling tunnel failure. Additionally, the damage levels of the tunnel were quantitatively assigned by computing the degree of membership that different damage levels had, based on the expectation normalization method. The methods of maximum membership principle, comprehensive evaluation value, and fuzzy entropy were considered to determine the tunnel damage levels and risk of occurrence. The application of this method at the Ashele copper mine demonstrates that it meets the requirement of risk assessment for deep tunnel failure and can provide a basis for large-scale regional tunnel failure control in deep metal mines.

Psychology has a pervasive but shallow engagement with Confucian philosophy, mainly referencing its popular form as a part of Chinese tradition. This special issue takes a more systematic view of Confucianism as comprehensive philosophy. Drawing from New Confucianism, it is argued that the signal contribution of Confucianism to psychology as human (rather than natural) science is an ontology of the moral mind (heaven and humanity in union). This holistic ontology makes the cultivation of benevolence (仁) a lifelong mission for Confucianists. Practices of self-cultivation are exemplified by a case study of Zeng Guofan, a Qing Dynasty official and scholar, who combined academics, calligraphy, meditation, diary writing and self-reflection to refine his character, nurture and educate his family, and be of service to society. Second, Confucianism’s traditional lack of interest in epistemology is addressed through the complementary (dialectical) principle of ‘one principle, many manifestations’, where methods of Western science can be incorporated into the investigation of practices such as brush calligraphy that are shown to have beneficial effects on mental and physical health. Confucianism can also be treated as an object of scientific inquiry: We find that even among highly educated Chinese people, understanding of Confucianism today is mostly fragmented and abstract. Confucian Psychology can be summarised as a psychology of aspirations for bettering the condition of humanity through character development and greater awareness of the situation to realise the endowment of moral mind. Finally, there are deep connections between Confucian and Indian psychology—both involve height psychology, a psychology of aspirations and for spiritual transformation.

What perceptions do group participants have about silent observers, what transferences are involved, what function can the listeners have for the group? In an anonymous survey and evaluation based on content analysis, almost all participants reported positive, and two thirds also negative impressions and perceptions. Observers were perceived as being familiar or supportive and as threatening or constraining to an approximately equal extent. There was no outright demonization or perception of a divide between the group leader(s) and the observers, as described in the older literature. Group participants also appear to perceive observers as representatives of their own superego, which are ‘silenced’.
