    Neuroaesthetics and the psychology of aesthetics
    (Baywood Publishing, 2009)
    As the term neuroaesthetics already denotes, cognitive neuroscientists have rediscovered the traditional discipline of empirical aesthetics. Over the past years, more and more researchers have begun to employ neuroscientific tools in the psychological study of aesthetic processing, or started to direct research in functional (cognitive) neuroscience toward the study of aesthetic processing. This chapter will trace how their endeavors are largely rooted in the classical, pragmatically dualistic approach of psychophysics. Here, objective measures of neural activity are correlated with reports of individual, subjective experience. This chapter will briefly review work showing that aesthetic processing, the evaluation or production of beauty, ugliness, prettiness, harmony, elegance, shapeliness, or charm, is governed by a host of factors such as stimulus symmetry, complexity, novelty, familiarity, artistic style, appeal to social status, and individual preferences. Cultures differ in what is considered beautiful and within cultures, people differ. Moreover, the degree of agreement between individuals differs between content domains. Therefore, aesthetic processing can be usefully considered from an evolutionary, historical, cultural, educational, cognitive, (neuro)biological, individual, personality, emotional, and situational perspective, and probably many more. Hence, it has been argued that human aesthetics, as a whole, is best approached from a number of different perspectives at several different levels of analysis. This chapter also reviews a framework of seven such vantage points for today's Psychology of Aesthetics (Jacobsen, 2006). (PsycINFO Database Record (c) 2016 APA, all rights reserved)

    Subjective appraisal of music
    (Wiley-Blackwell, 2009-07-24)
    Brattico, Elvira
    ;
    In the neurosciences of music, a consensus on the nature of affective states during music listening has not been reached. What is undeniable is that subjective affective states can be triggered by various and even opposite musical events. Here we review the few recent studies on the neural determinants of subjective affective processes of music, contrasted with early automatic neural processes linked to the objective universal properties of music. In particular, we focus on the evaluative judgments of music by subjects according to its aesthetic and structural values, on music‐specific emotions felt by listeners, and on conscious liking. We then discuss and seek to stimulate further research on the interplay between the emotional attributes of music and the subjective cognitive, psychological, and biographic factors, such as personality traits and cognitive strategies of listening. We finally draw the neuroscientist's attention to the sociocultural context as a relevant variable to study when considering music as an aesthetic domain.

    Electrophysiology
    (Oxford University Press, 2020-07-09) ;
    Klein, Stina
    One important method that can be applied for gaining an understanding of the implementation of aesthetics in the brain is that of electrophysiology. Cognitive electrophysiology, in particular, allows the identification of components in a mental processing architecture. The present chapter reviews findings in the neurocognitive psychology of aesthetics, or neuroaesthetics, that have been obtained with the method of event-related brain potentials (ERPs), as derived from the human electroencephalogram (EEG). The cognitive-perceptual bases, as well as affective sub-stages of aesthetic processing have been investigated, and those are described here. The ERP method allows for the identification of mental processing modes in cognitive and aesthetic processing. It also provides an assessment of the mental chronometry of cognitive and affective stages in aesthetic appreciation. As the work described here shows, distinct processes in the brain are engaged in aesthetic judgments.

    Einen Ansatz zur Unterstützung manueller Tätigkeiten stellen Exoskelette dar. Durch den Einsatz dieser Systeme lassen sich verschiedene biomechanische sowie arbeitsphysiologische Effekte erzielen. Verschiedene Faktoren haben hierauf Einfluss. In Studien mit einem Unterstützungssystem „Lucy“ hat sich gezeigt, dass mit physischer Unterstützung eine subjektive und quantitative Entlastung erzielt sowie die Konzentrationsleistung gesteigert werden kann.

    Galois Theory and Hilbert Irreducibility Theorem

    In this dissertation, we are studying abstract algebra; mostly, our focus is on studying Galois theory in depth, and then we will study the proof of our main theorem, "Hilbert Irreducibility Theorem," which states that given any irreducible polynomial g (t_1, t_2,...., t_n, x) over the rational numbers, there are an infinite number of rational n-tuples (a_1, a_2,...., a_n) such that f (a_1, a_2,..., a_n, x) is irreducible over the rational numbers. I have omitted the basics of abstract algebra, such as group, ring, and field theory, and motivated the reader to read a basic book to learn these topics. I have presumed that the reader knows linear algebra. I started my dissertation with an introduction to group characters and then extended our discussion to Galois extension and normal extension to provide the basis for studying the Fundamental Theorem of Galois Theory. Then, we fixed our focus on Kummer Extensions and Cyclotomic Extensions. To end our discussion of Galois' theory, we studied solvable groups. Then some complex analysis theorems have been stated, which we will use in our proof of Hilbert's irreducibility theorem. A whole chapter has been dedicated to studying lemmas to prove our theorem, and then in the last chapter, we have proved our theorem.

    China and the limits of hypothetical hegemony
    (Taylor & Francis, 2024-02-29)
    How is China’s rise leaving its mark on the practices, norms and institutions of international politics? In their article, “China and the Logic of Illiberal Hegemony”, Darren J. Lim and G. John Ikenberry offer a provocative answer to this question. Lim and Ikenberry set out to identify “the logic and practices of an ideal-type order that most closely suits China’s preferences.” They distil three organizational principles or logics that could characterize a potential Chinese model of international order: the logic of difference, the logic of win-win, and the logic of partnerships. The authors argue that while such logics may not be illiberal per se, by attracting autocratic state followers and being based on pragmatic interstate bargaining rather than formal institutions, they may generate illiberal outcomes over time. If this argumentation holds, it raises considerable doubt about the sustainability of liberal international order in the face of China’s continued rise.

    A traditional two-section watch bill (6 hours on / 6 hours off, starting at midnight – “6/6”) and a two-section watch bill better adapted to the human circadian rhythm (watches of 7, 5, 5, and 7 hours duration, starting at 3 a.m. – “7-5-5-7”) were trialed on two vessels of the German Navy with 67 study participants in a crossover design. Questionnaires were used to assess subjective sleepiness (ESS, KSS) and subjective fatigue (FSS). The psychomotor vigilance task (PVT) was self-administered with wearable devices before and after each watch. Over the course of seven days at sea, PVT performance worsened significantly with the 6/6, but not with the 7-5-5-7 watch bill. In the 6/6 watch bill, number of participants with excessive sleepiness and high levels of fatigue was higher than in the 7-5-5-7 watch bill although not at a statistically significant level. Marked differences between watch bills in crew performance started to emerge after 6 days.

    Hey CLIP, can you capture semantics in brand names?

    Congruence between brand names and other flagships of a brand are important tools to effectively communicate to, and set the right expectations in consumers. In this study, we explore congruence of brand features as a problem that could potentially be evaluated by computational models trained on cross-modal stimuli such as CLIP. As a by-product we explore to what extent these models capture sound symbolic associations in our stimuli set, and analyse the relationship between (sub-) lexical information and shape dimensions in brand logos. Instead of human participants, we employ CLIP- and BERT-based computational models to make decisions about similarity between a multitude of brand names, brand descriptions and brand logos. We show that our results support proposals of statistical co-occurrence as an underlying mechanism of sound symbolic associations, and argue that CLIP can be carefully used as a tool for maneuvering through naming and logo design decisions.
