Assessment of physical strength from gait: data from the Maasai of Tanzania
In industrialized societies, male gait provides information about physical strength. Male physical strength may be used by men and women to assess the fighting ability of rivals and the quality of potential mates, respectively. Women more than men discriminate between strong and weak walkers when assessing gait attractiveness. We presented videos of British men’s gait—pre-categorized into strong and weak walkers—to male and female members (n 1⁄4 100) of the traditional Maasai in northern Tanzania in Africa. Maasai men and women judged the gaits of physically strong men less attractive than those of weak men and judged strong walkers to be weaker than weak walkers. These findings counter results from industrialized societies where participants accurately assessed strength from gait, thus arguing against a universal perception of physical strength from gait information.
The article concerns R. Wollheim’s theory of twofoldness, the one of the most acclaimed analytical theories of pictorial representation. Wohhleim has pointed to the structural distinction of seeing pictures from seeing objects and situations face-to-face, thus proposing the theory of seeing-in and twofoldness. This conception presupposes the split, simultaneous seeing of the picture’s object and material surface. Considering the basic influences, features and shortcomings of Wollheim’s theory, author specifies the question of to what extent the scope of this theory is limited to artistic pictures. Alongside with this theory’s reconstruction and critique, the article provides its interpretation based on spatially-oriented definitions of twofoldness (B. Nanay, J. Kulvicki) coupled with the actualization of the distinction between representational content of a picture and its figurative content. The first one includes all spatial relations that can be seen in it, the second one – all that can be seen in it and described by non-abstract concepts. Wollheim reframed to apply this distinction to his notion on twofoldness. But it gives the possibility to bring out the convincing definition of twofoldness as the simultaneous visual experience of pictorial surface (i.e., some material object in viewer’s egocentric space) and of representational content (i.e., semantically active spatial relations which one sees in the picture). This interpretation may be considered a useful instrument for non-reductionist description of pictorial experience and pictures’ ontological duality, hence it is devoid of Wollheim’s psychologism while maintaining his focus on visuality. Moreover, it provides some opportunities for applying Wollheim’s theory beyond the contexts of analytical philosophy of pictures, thus connecting it to the problems of phenomenological and hermeneutic theories of image.
This paper discusses design process as a creative activity along with conceptual correlations of the semiotics developed by Charles Sanders Peirce. The central aim of this paper is to examine one of the most important concepts in Peirce’s theory related to design praxis: the concept of abduction. Abduction is the driving force behind creation and a way of producing new ideas. Peirce’s original concept is fundamental in order to maintain constant commitment to innovation required by design. To transmit messages in a creative way it is more efficient to intensely work with associations by similarity in order to obtain signs rich in information and analogies. Design communicates by all its constituent elements: shape, function, colour, material, technique, technology, etc. Therefore, signs of design share peculiar values of artistic signs as well as those of communicative ones. The associated information is as much aesthetic (shape) as it is semantic (content). The appropriation of Peircean concepts contributes to the understanding of the creative process, which in turn is crucial for understanding new possibilities by means of design.
Recent events in Ukraine and Russia and the subsequent incorporation of Crimea into the Russian state, with the support of some circles of inhabitants of the peninsula, have shown that the desire of people to belong to the Western part of Europe should not automatically be assumed. Discussing different perceptions of the Ukrainian-Russian war in neighbouring countries, this book offers an analysis of the conflicts and issues connected with the shifting of the border regions of Russia and Ukraine to show how ’material’ and ’psychological’ borders are never completely stable ideas. The contributors – historians, sociologists, anthropologists and political scientists from across Europe – use an interdisciplinary and comparative approach to explore the different national and transnational perceptions of a possible future role for Russia.
Plato’s interest in vision and the visual is multifaceted, and complex. Visual words and images are frequent in the dialogues along with many direct and indirect discussions of physiological, intellectual, and social vision. The increased emphasis in recent scholarship on the importance of visuality in Plato is a part of a ‘scopic turn,’ the effect of which was to ground interpretations of the history of western European philosophy and metaphysics in its entirety in certain optical premises.
This paper deals with the perception of English language teaching profession at a secondary school level by university students who specialize in languages. Survey results demonstrate that though respondents find English teaching content appealing, the perceptions of unattractive low pay and high workload stop them from choosing a teaching career. Also, students are uninformed about labor conditions for school teachers. Internal motivation such as personal qualities and preferences is the primary incentive to choose English language teaching profession.
Many environmental stimuli present a quasi-rhythmic structure at different timescales that the brain needs to decompose and integrate. Cortical oscillations have been proposed as instruments of sensory de-multiplexing, i.e., the parallel processing of different frequency streams in sensory signals. Yet their causal role in such a process has never been demonstrated. Here, we used a neural microcircuit model to address whether coupled theta–gamma oscillations, as observed in human auditory cortex, could underpin the multiscale sensory analysis of speech. We show that, in continuous speech, theta oscillations can flexibly track the syllabic rhythm and temporally organize the phoneme-level response of gamma neurons into a code that enables syllable identification. The tracking of slow speech fluctuations by theta oscillations, and its coupling to gamma-spiking activity both appeared as critical features for accurate speech encoding. These results demonstrate that cortical oscillations can be a key instrument of speech de-multiplexing, parsing, and encoding.
This collection of essays was published in a form of a catalogue for one of the propgrams screened at the Yamagata International Documentary Film Fstival in October 2019. The program entitled "The Creative Treatment of Grierson in Wartime Japan" was co-organized by the Yamagata International Documentary Film Festival and the National Film Archive of Japan and presented a broad variety of wartime Japanese documentaries as well as British and Soviet films that have influenced them. The collection of essays explores the development of wartime Japanese documentary cinema from variety of historical and theoretical perspectives.
Hypoxia of trophoblast cells is an important regulator of normal development of the placenta. However, some pathological states associated with hypoxia, e.g. preeclampsia, impair the functions of placental cells. Oxyquinoline derivative inhibits HIF-prolyl hydroxylase by stabilizing HIF-1 transcription complex, thus modeling cell response to hypoxia. In human choriocarcinoma cells BeWo b30 (trophoblast model), oxyquinoline increased the expression of a core hypoxia response genes along with up-regulation of NOS3, PDK1, and BNIP3 genes and down-regulation of the PPARGC1B gene. These changes in the expression profile attest to activation of the metabolic cell reprogramming mechanisms aimed at reducing oxygen consumption by enabling the switch from aerobic to anaerobic glucose metabolism and the respective decrease in number of mitochondria. The possibility of practical use of the therapeutic properties of oxyquinoline derivatives is discussed.
