Abstract During natural vision, our brains are constantly exposed to complex, but regularly structured environments. Real-world scenes are defined by typical part–whole relationships, where the meaning of the whole scene emerges from configurations of localized information present in individual parts of the scene. Such typical part–whole relationships suggest that information from individual scene parts is not processed independently, but that there are mutual influences between the parts and the whole during scene analysis. Here, we review recent research that used a straightforward, but effective approach to study such mutual influences: By dissecting scenes into multiple arbitrary pieces, these studies provide new insights into how the processing of whole scenes is shaped by their constituent parts and, conversely, how the processing of individual parts is determined by their role within the whole scene. We highlight three facets of this research: First, we discuss studies demonstrating that the spatial configuration of multiple scene parts has a profound impact on the neural processing of the whole scene. Second, we review work showing that cortical responses to individual scene parts are shaped by the context in which these parts typically appear within the environment. Third, we discuss studies demonstrating that missing scene parts are interpolated from the surrounding scene context. Bridging these findings, we argue that efficient scene processing relies on an active use of the scene's part–whole structure, where the visual brain matches scene inputs with internal models of what the world should look like.

Real-world scenes are defined by typical part-whole relationships, where the meaning of the whole scene emerges from configurations of localized information present in individual parts of the scene.

Here, we review recent research that used a straightforward, but effective approach to study such mutual influences: by dissecting scenes into multiple arbitrary pieces, these studies provide new insights into how the processing of whole scenes is shaped by their consistent parts and, conversely, how the processing of individual parts is determined by their role within the whole scene.

Even before they really existed, I deeply believed that virtual worlds would have a profound impact on the real world, ultimately affecting the lives of people worldwide, in much the same way that the World Wide Web itself has brought about a dramatic transformation in how we communicate. Now that Second Life—and more broadly, virtual worlds—have become at least "worthy of criticism,” I am all the more convinced that this will prove to be true. We will soon see virtual worlds expand from millions of active users to billions.

The socio-environmental challenges the world faces are ‘swamps’: situations that are messy, complex, and uncertain. The aim of this paper is to help disciplinary scientists navigate these swamps. To achieve this, the paper evaluates an integrative framework designed for researching complex real-world problems, the Integration and Implementation Science (i2S) framework. As a pilot study, we examine seven inter and transdisciplinary agri-environmental case studies against the concepts presented in the i2S framework, and we hypothesise that considering concepts in the i2S framework during the planning and delivery of agri-environmental research will increase the usefulness of the research for next users. We found that for the types of complex, real-world research done in the case studies, increasing attention to the i2S dimensions correlated with increased usefulness for the end users. We conclude that using the i2S framework could provide handrails for researchers, to help them navigate the swamps when engaging with the complexity of socio-environmental problems.

Claude Pichois claims that Baudelaire’s debt towards Fourier is limited to the notion of universal analogy. There is, however, another aspect of Fourier’s thought, one that had a profound impact on Les Fleurs du mal: the denunciation of universal evil. In this respect, the poet draws on Fourierist vocabulary to express his own vision of the world. This article provides examples of lexical borrowings by the poet who, disillusioned by the failure of the dreams of the Fourierist school, uses the word sin to stigmatize “the reign of evil” under which, according to Fourier, his contemporaries were living.

The article discusses in detail the essence and meaning of ritual as a social action. The study of the nature of this phenomenon involves, first of all, the study of various approaches to the definition of the concept of "ritual" and related phenomena. Analyzing the existing definitions, the author comes to the conclusion that "ritual" is a certain set of actions that have symbolic meaning. The symbolism of the ritual is manifested in its connecting role with the world of the sacred, sacred. The article emphasizes that in the consciousness of a person in a traditional society, the sacred world is present in the real world through ritual. As an archaic form of culture, ritual was also a way of regulating and maintaining collective life. The ritual served as a means of integrating and maintaining the integrity of the human community, giving it stability. Therefore, the article focuses on the social functions of the ritual in both public and individual life.

The present communication is primarily nomenclaturial–classical taxonomy is only touched in a side note on a diagnosis. It uses technical terminology coined by Alain Dubois, who is interested in the study of the concepts and theory of biological nomenclature (i.e. the “objective connection between the real world of populations of organisms and the world of language” (Dubois & Ohler 1997)), and who discusses the current ‘International Code for Zoological Nomenclature’ [hereafter just called ‘the Code’] in great detail. The terms are explained where necessary–but see also the glossaries in Dubois et al. (2019) and the works by A. Dubois cited below.

Trying to interpret oneself and the other in the world, the traditional Man has established a real world and an otherworld. Specific herbal and animal attributes were ascribed to particular people who allegedly had the power to communicate between worldliness and transcendence. Also some human characteristics were linked with herbal and animal mediators. These attributes were folklorized as miraculous powers. Such supernatural beings from South Slavic traditional conceptionsof the world have been largely associated with the pre-Christian deities and their degradations, based on the observed real attributes of the vegetal and animal species. The interdisciplinary comparative way of treating South Slavic folklore real-unreal motifs through time and space in this article is its ethnological, animalistic and anthropological contribution.
