The issues of molding products from polymer materials and composites using additive technologies (ADT), which are one of the modern trends in the technology of processing polymer materials and composites into products with complex geometry of various standard sizes, are considered. It is shown that the creation of ADT is a complex scientifi c and technical task. The data on TOTAL-Z LLC, the Russian manufacturer of 3D-printers, and model range of printers are presented. The role of RTU MIREA’s Department of Chemistry and Technology of Plastics and Polymer Composites Processing, together with TOTAL-Z LLC, in the organization of the first educational and scientific center for additive polymer technologies, training and development of additive technologies is shown.

Abstract Grassroots digital fabrication workshops (such as FabLabs), and associated technologies (such as 3D printers), are attracting increasing attention as a potential source for addressing a variety of social and environmental challenges. Through an analysis of an in-depth case study on FabLabs, this paper aims to provide insights into the practices emerging in these workshops and realities of the relationship between its members and technologies that are currently under-researched. It does this by drawing upon the domestication literature that concerns itself with how people use, adapt and reject technologies and integrate them into their life. The paper examines the significance of the interactions between people and technologies in FabLabs and offers concluding reflections on the role of these relationships within broader social and environmental changes.

Radically shifting personal experience of the visual image from virtual worlds like Second Life, from flat screens, cinema, and paper to physical forms, subverts the predominance of the digital realm. Living on the surface of the screen minimizes the tactility of materials and the resonance of memory and meaning embodied in objects. Digital 3D cinema, 3D television, and 3D cameras are precursors at the threshold of transforming digital into physical. The image flexes from screen to object with 3D printers and CNC machines. In the medical profession, computer 3D images from CT scans are transformed to remotely controlled, physical surgeries. Recently thinking experiments use brain activity to remotely control robotic arms. Vehicles for physicalizing the image from paper, screen, and from one’s imagination and thinking in the brain, manifest three-dimensional, palpable, sensory, tactile, objectified experiences. How will this phenomena transform modes of digital communication, physical interactions, and production on both the global and the personal scales? How will the material role of the computer prescribe new creative activities, new modes of artistic expression?

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.

Abstract The authors do the field of cultural evolution a service by exploring the role of non-social cognition in human cumulative technological culture, truly neglected in comparison with socio-cognitive abilities frequently assumed to be the primary drivers. Some specifics of their delineation of the critical factors are problematic, however. I highlight recent chimpanzee–human comparative findings that should help refine such analyses.

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.
