One of the unique insights provided by the growing number of fully sequenced genomes is the pervasiveness of gene duplication and gene loss. Indeed, several metrics now suggest that rates of gene birth and death per gene are only 10–40% lower than nucleotide substitutions per site, and that per nucleotide, the consequent lineage‐specific expansion and contraction of gene families may play at least as large a role in adaptation as changes in orthologous sequences. While gene family evolution is pervasive, it (...) may be especially important in our own evolution since it appears that the “revolving door” of gene duplication and loss has undergone multiple accelerations in the lineage leading to humans. In this paper, we review current understanding of gene family evolution including: methods for inferring copy number change, evidence for adaptive expansion and adaptive contraction of gene families, the origins of new families and deaths of previously established ones, and finally we conclude with a perspective on challenges and promising directions for future research.

The ability to create and perceive art has long been understood as an exceptional human trait, which should differentiate us from the rest of the organisms or robots. However, with the uprising of cognitive sciences and information stemming from them, as well as the evolutionary biology, even the human being began to be understood as an organism following the evolutionarily and culturally obtained algorithms and evaluation processes. Even fragile and multidimensional phenomena like beauty, aesthetic experience or the good have lately (...) been analyzed using computational aesthetics, neuroaesthetics, and neuroethics, suggesting that the entire aesthetics, art or ethics can be understood as a result of a certain algorithmic data analysis. In the following article, I will attempt to think about the concept of computational aesthetics and the possibilities, benefits and shortcomings of artificial intelligence in the creation, as well as in perception and evaluation of artworks. I will introduce multiple models of artistic work based on AI, quality/originality evaluating computer programs, as well as mechanisms of its perception. In the end, I will attempt to present the basic aesthetic problems stemming from the development of AI and its usage in the field of art. (shrink)

The study explores the etymological and semantic challenges associated with the term beauty. The authors highlight that beauty is among the most vague and multifaceted concepts. As a result, its users often grasp completely different aspects/dimensions of it. After addressing etymological differences and conducting a conceptual analysis of its synonyms, the authors present empirical findings and a model outlining the semantic space of the term beauty. In the second part of the study, the authors shed light on the reasons behind (...) the use of this ambiguous term, particularly focusing on its evolutionary and existential significance. The conclusion of the study draws attention to the fact that, despite the vagueness of the concept, beauty continues to play a key role in our lives, reflecting our need to share it, and portraying the human being as homo aestheticus.

Introduction for Reframing Beauty: Body, Environment, Art, the thematic issue of ESPES. The Slovak Journal of Aesthetics.

Interaction between adults and infants by nature constitutes a strong powerasymmetry relationship. Based on the assumption that communicative practices with infants are inseparably intertwined with broader cultural ideologies of good child care, this paper will contrast how parents in two distinct socio-cultural communities deal with power asymmetry in interactions with 3-months old infants. The study consists of a microanalysis of videotaped free play mother-infant interactions from 20 middle class families in Muenster, Germany and 20 traditional farming Nso families in Kikaikelaki, (...) Cameroon. Analysis followed a discursive psychology approach. The focus of analysis is on how mothers handle and negotiate power-distance in these interactions and what discursive strategies they draw on. Mothers in both groups used various forms of directives and control strategies. The Muenster mothers, however, mainly used mitigated directives that can be seen as strategies to reduce the competence gap between mother and child, while the Nso mothers mainly used upgraded directives to stress the hierarchical discrepancy between mother and child. The different strategies are discussed in light of the prevailing broader cultural ideologies and the normative orientations that they reflect. Finally, the findings are discussed with regard to possible developmental consequences of these distinct cultural practices for the child. Keywords: power-asymmetry; mother-infant interaction; discursive psychology; culture; Nso farmers; Muenster middle class families. (shrink)

The article presented here thematizes Heidegger’s view of affectivity, experience and passions in the context of his reading of Nietzsche’s philosophy. Following the basic plan of Heidegger’s analysis of moods (especially fear and anxiety) in Being and Time, the author attempts to show us what Heidegger’s phenomenology of affectivity would have enabled us to see in the phenomenon of anger if Heidegger had elaborated it. The author analyzes anger as a social and moral emotion through the prism of what “angry” (...) phenomena have in common; what we perceive when we are angry; and what it is for us that anger is even about. In conclusion, anger is presented as something existential that not only uncovers existence itself, but above all the relationship of our will to phenomena that are not acceptable to us. (shrink)

There is a constructive method to define a structure of simple k-cyclic Post algebra of order p, L p,κ, on a given finite field F, and conversely. There exists an interpretation Ф₁ of the variety V generated by L p,κ into the variety V) generated by F and an interpretation Ф₂ of V) into V such that Ф₂Ф₁ = B for every B ϵ V and Ф₁₂ = R for every R ϵ V). In this paper we show how we (...) can solve an algebraic system of equations over an arbitrary cyclic Post algebra of order p, p prime, using the above interpretation, Gröbner bases and algorithms programmed in Maple.
