Ecological aesthetic education takes the holistic ecological view as the philosophical basis, advocating appreciating nature and caring about life with an aesthetic attitude, realizing the coexistence of man and nature, and promoting the harmonious development of man and society. In view of this, the current school ecological aesthetic education should deepen the integration of large and small ecological aesthetic education discipline system construction, improve the comprehensive quality of ecological aesthetic education teachers, combine social aesthetic education to enrich ecological aesthetic education extracurricular practice, and train new people for the construction of Chinese modern ecological civilization.

Institutional thinking, a concept that underscores the importance of internal perspectives and the enduring purposes of institutions, plays a critical role in maintaining societal stability and ethical governance. This paper explores the dual nature of institutional thinking, highlighting its positive aspects and inherent dangers. Through an examination of economic, political, and philosophical forces, the paper identifies modern challenges that undermine long-term commitments and ethical values within institutions. By drawing on historical and contemporary examples, including slavery, Nazism, and discriminatory practices, the discussion provides a comprehensive understanding of how institutional thinking can both promote human well-being and perpetuate systemic issues. The paper concludes by emphasizing the need to reaffirm institutional values, promote long-term thinking, and balance individual rights with collective responsibilities to harness the positive aspects of institutional thinking while mitigating its risks.

Clustering technics, like k-means and its extended version, fuzzy c-means clustering (FCM) are useful tools for identifying typical behaviours based on various attitudes and responses to well-formulated questionnaires, such as among forensic populations. As more or less standard questionnaires for analyzing aggressive attitudes do exist in the literature, the application of these clustering methods seems to be rather straightforward. Especially, fuzzy clustering may lead to new recognitions, as human behaviour and communication are full of uncertainties, which often do not have a probabilistic nature. In this paper, the cluster analysis of a closed forensic (inmate) population will be presented. The goal of this study was by applying fuzzy c-means clustering to facilitate the wider possibilities of analysis of aggressive behaviour which is treated as a heterogeneous construct resulting in two main phenotypes, premeditated and impulsive aggression. Understanding motives of aggression helps reconstruct possible events, sequences of events and scenarios related to a certain crime, and ultimately, to prevent further crimes from happening.
