The scandium effect in multicomponent alloys
Despite its excellent elemental properties, lightweight nature and good alloying potential, scandium has received relatively little attention in the manufacturing community. The abundance of scandium in the Earth's crust is quite high. It is more abundant than silver, cobalt, lead and tin. But, because scandium is so well dispersed in the lithosphere, it is notoriously difficult to extract in commercial quantities – hence low market availability and high cost. Scandium metallurgy is still a largely unexplored field – but progress is being made. This review aims to summarise advances in scandium metallurgical research over the last decade. The use of scandium as a conventional minor addition to alloys, largely in structural applications, is described. Also, more futuristic functional applications are discussed where details of crystal structures and peculiar symmetries are often of major importance. This review also includes data obtained from more obscure sources (especially Russian publications) which are much less accessible to the wider community. It is clear that more fundamental research is required to elevate the status of scandium from a laboratory-based curiosity to a mainstream alloying element. This is largely uncharted territory. There is much to be discovered
Features of сreativity in social interaction among convicts who have committed self-serving and aggressively violent crimes
The article presents the results of an empirical study of the features of creativity in social interaction on a sample of male convicts serving sentences in a penal colony (N = 18, convicted of fraud and selfish violence, and N = 20 convicted of aggressively violent crimes). The relationship between the fluency indicators in situations of positive and negative connotations (revenge for damage and lies in romantic relationships) with personal values (the Sh.Shwartz questionnaire), aggression (the Bassa-Perry questionnaire), temperament characteristics (K.Cluninger's questionnaire), behavior (Questionnaire of M.Ranko et al.). Corporations of convicts found correlations of fluency in situations with negative connotation with hostility and anger, while in aggressively violent criminals the refusal of revenge is mediated by the highest values of social focus. The results show that creativity in social interaction in situations with negative and positive connotations is not a single construct: it should be differentiated according to the antisocial and prosocial orientation. The limitations of the study are indicated and directions for further research are suggested
