Human Coder

We analysed a set of uninstructed pedestrian trajectories automatically tracked in a public area, and we asked a human coder to assess their group relationships. For those pedestrians who belong to the groups, we asked the coder to identify their apparent purpose of visit to the tracking area and apparent gender. We studied the quantitative dependence of the group dynamics on such properties in the case of triads (three people groups) and compared them to the two pedestrian group case (dyads), studied in a previous work. We found that the group velocity strongly depends on relation and gender for both triads and dyads, while the influence of these properties on spatial structure of groups is less clear in the triadic case. We discussed the relevance of these results to the modelling of pedestrian and crowd dynamics, and examined the possibility of the future works on this subject.

Group Relationships

Abstract Triadic awareness, or knowledge of the relationships between others, is essential to navigating many complex social interactions. While some animals maintain relationships with former group members post-dispersal, recognizing cross-group relationships between others may be more cognitively challenging than simply recognizing relationships between members of a single group because there is typically much less opportunity to observe interactions between individuals that do not live together. We presented acorn woodpeckers (Melanerpes formicivorus), a highly social species, with playback stimuli consisting of a simulated chorus between two different individuals, a behavior that only occurs naturally between social affiliates. Subjects were expected to respond less rapidly if they perceived the callers as having an affiliative relationship. Females responded more rapidly to a pair of callers that never co-occurred in the same social group, and responded less rapidly to callers that were members of the same social group at the time of the experiment and to callers that last lived in the same group before the subject had hatched. This suggests that female acorn woodpeckers can infer the existence of relationships between conspecifics that live in separate groups by observing them interact after the conspecifics in question no longer live in the same group as each other. This study provides experimental evidence that nonhuman animals may recognize relationships between third parties that no longer live together and emphasizes the potential importance of social knowledge about distant social affiliates.

AbstractThe poloidal eigenmode of the geodesic acoustic mode (GAM) is studied in the limit of high safety factor. In this limit, the poloidal gyroradius cannot be treated as a perturbation or as an expansion parameter. Analytical expressions for the poloidal structure of the GAM potential, the radial wavenumber dependence of the frequency, the phase velocity, and the group velocity are obtained. The spatial structure of the poloidal eigenmode including the higher-order gyroradius effect is revealed theoretically.

The Given

The article is devoted to the consideration of the features of the verbalization of the concept HAIR in the English language. The purpose of the work is to examine the structure of the English concept HAIR as a fragment of the English-language picture of the world of the English-speaking society. The main attention is focused on the analysis of the language embodiment of the given concept in the naïve and professional varients of the picture of the world. The English concept HAIR is a fragment of the conceptual picture of the world, which is reflected in the language picture of the world, namely in its three fragments, verbalized by the constituents of the lexical-semantic groups, distinguished according to the somatic feature. They are head hair, facial hair, body hair. The analysis of the language and speech material showed that the structure of the English concept HAIR in the naive picture of the world is a three-component formation, which consists of a core, a nuclear zone and a periphery. The core includes such conceptual features as somatic and gender. The nuclear zone includes objective and various associative conceptual features, namely: age, thinness, protection, beauty, strength / success, value. The periphery of the concept consists of socially-identifying functions - professional, religious and social-group. The core of the concept HAIR in the professional picture of the world includes such conceptual features as somatic, gender, structure and development. The nuclear zone includes objective conceptual features, namely: health, age, protection. The periphery of the concept consists of professional, religious, and social-group social-identifying functions. Thus the periphery of the given concept in the two variants of the picture of the world is identical. The prospects for further research are seen in the consideration of the mentioned aspects of verbalization on the material of English artistic speech as well as professional discourse.
