To the question of restoring symbol sequences encoding noisy periodic functions

In business informatics, one of the research subjects is the analysis of data on processes in applied subject areas; here problems of qualitative analysis arise. Such problems arise, for example, in the qualitative study of log files of business processes, in the analysis and prediction of time series and other processes of a different nature. Quite often, to represent information about the processes under study, the methods of qualitative analysis use symbolic coding, which makes it possible to remove unnecessary detailing of numerical descriptions. The relevance of this study is due to the fact that when working with the raw data, researchers often face the presence of noise and distortions of the data, which significantly complicates the solution of the problems of qualitative analysis. When working with symbolic representations of the processes under study, which quite often have a periodic nature, we observe noise of deletion, insertion and replacement of symbols, which complicate the solution of the problem of revealing and analyzing the periodicity. This article deals with the problem of recovering periodic symbolic sequences obtained by coding from samples of continuous periodic functions and distorted by noise of insertion, replacement and deletion of symbols. Trigonometric functions are considered as a specific example of synthetic time series data. To encode trigonometric functions, alphabets of various cardinalities are used. The article presents an experimental study of the dependence of the quality characteristics of the method of period and a periodically repeating fragment recovery, previously proposed by the authors and improved in this study. For alphabets of different cardinalities at fixed sampling intervals, the fraction of sequences with a satisfactorily reconstructed period and the relative error in determining the period are given. The quality of reconstruction of a periodically repeating fragment is estimated by the edit distance from the reconstructed periodic sequence to the original sequence distorted by noise.

How perception and attention participate in reading skill?

Reading creates accessibility to the outer world information and is an integral skill for academic achievement. It involves visual perception, reasoning at symbolic level (text reading) and phonological processing. But does perception, visuospatial processing at pre-symbolic level affect reading skill? To understand and untangle the mechanism fifty children with reading problem (developmental dyslexia, DDC) and twentyfive age-matched typical readers (healthy controls, HC) participated. In DDC, the variable-performance of non-symbolic visual search (pictorial-level) was associated with bilateral brain activity (functional MRI) of ventral stream (inferior occipital and fusiform) and greater involvement of frontal-prefrontal regions, suggesting the modified dorsal route-gating for figure-ground filtering. Performance variability in picture-concept reasoning (71.9% and significant group mean difference) and visuospatial-organization (51.3%) of DDC children indicate attentional or executive differences at nonsymbolic level. In symbolic discrimination performance, no significant difference observed for single alphabet or number (digit) reading but significant differences at word level for visual and phonological performance (considering orthographic differences), attributes to distractor-inhibition problems. Nonsymbolic to symbolic coding/decoding speed and writing error (copying) differences are suggestive of execution variability rather than motor coordination in DDC. In HC, the top-down dorsal route gating and hypoactivity induced in right frontal-anterior cingulate cortices, play a major role in reading by allocating spatial attention and inhibiting distractors. It has been elaborated in the &neurobiological model&

Development of Infrastructure and Changes in the Social Space of Kharkiv at the Turn of the 19th – 20th Centuries

The article explored the impact of urban infrastructure on the social space of Kharkov in the late 19th – early 20th centuries. Kharkiv municipality began to implement large-scale infrastructure projects that contributed to solving urgent sanitary-epidemiological and social problems from the 1870s. The first significant technological component of the infrastructure was water supply. Telephone communications, electric lighting, sewage, horse and electric trams started to function in Kharkiv at that time. Networks of medical, educational and cultural institutions were widely developed. The publication clarified the role of certain actors in the creation and maintenance of infrastructure elements. In particular, thanks to Kharkiv municipality declared the basics of collective safety, occupational health, social ecology and formed communicative relations of infrastructure institutions with consumers. Attention is also focused on the role of Kharkiv philanthropic organizations and expert groups, which contributed to the awareness of citizens of such an ethical principle as social responsibility. In the article considered changes in the material substrate of the social space of Kharkiv. It is noted that although the center of the city was the zone of “prestige”, however, the localization of the components of the city infrastructure gradually expanded, which became one of the important features of the modernization of the social space of the city. Networks of hospitals and educational institutions covered remote Kharkiv areas. Public transport and stationary trading establishments become part of the everyday practices of residents of the city's environs. It is concluded that the development of infrastructure not only changed the physical appearance of the city, but also transformed social practices and the symbolic coding of social space.

BASIC PRINCIPLES FOR CREATING AN EFFECTIVE VISUAL MESSAGE

The article is devoted to the definition of the basic principles of creating a visual message, the adherence to which contributes to the effectiveness of its influence on the target audience. In the context of Russia's hybrid war against Ukraine, counter-terrorism issues are more urgent than ever. In light of world research in psychology, the effectiveness of perceiving information depends, in particular, on the dominant channel of perception (audio, visual, kinesthetic). However, the results of a number of psychological experiments in the field of visual perception have shown that it is better to understand, memorize and reproduce the information we receive through our visual channels. Modern research of social problems leads to understanding - the world has become visual. Man of our time is under constant influence of visual content. So reporting to the consciousness of the necessary information effectively through this channel. Thus, the very visual message is an effective tool for counterpropaganda and for informing the population in the interests of the Armed Forces of Ukraine. The result of the research is based on the study of the peculiarities of the visual perception of information about the world and, related to this, the possibilities of using two-dimensional space in the interests of creating products of psychological influence. In addition, an analysis was conducted of the psychological effect of color on the human subconscious, the emotiogenic structure of color combinations, the psychological effects of symbolic coding of information, general rules of composition, examples of successful graphic marketing. In forming practical recommendations for the implementation of the proposed principles, general publishing approaches to the creation of printed visual products, the technological features of different types of media, the effectiveness of distribution channels for products of psychological influence and the results of the analysis of the target audience were taken into account.

Prescribing the behavior of Weil–Petersson geodesics in the moduli space of Riemann surfaces

We study Weil–Petersson (WP) geodesics with narrow end invariant and develop techniques to control length-functions and twist parameters along them and prescribe their itinerary in the moduli space of Riemann surfaces. This class of geodesics is rich enough to provide for examples of closed WP geodesics in the thin part of the moduli space, as well as divergent WP geodesic rays with minimal filling ending lamination. Some ingredients of independent interest are the following: A strength version of Wolpert's Geodesic Limit Theorem proved in Sec. 4. The stability of hierarchy resolution paths between narrow pairs of partial markings or laminations in the pants graph proved in Sec. 5. A kind of symbolic coding for laminations in terms of subsurface coefficients presented in Sec. 7.

Durkheim, Development and the Devil: A Cultural Sociology of Community Conflict

Durkheim’s The Elementary Forms of Religious Life provides a theory of the eminently social processes by which people, places, times and things come to be seen as sacred or profane. He demonstrates how the sacred is a locus of collectivization essential to the formation of the solidaristic bonds that characterize a moral community. Recent work in cultural sociology suggests that the mobilization of the binary discourse of civil society—the sacred/profane—is key to democratic deliberation in the public sphere (Alexander 2006). Drawing on participant observation, local media resources, and printed and online materials, this paper examines the deployment of this binary discourse in a conflict around the rezoning of agricultural land in rural Nova Scotia (2009-2011). Substantively, this case demonstrates how the symbolic coding of rural/agricultural space as sacred played a significant role in the rejection of the proposed rezoning. At a theoretical level, this paper reaffirms that the Durkheimian vision of the symbolic power of the sacred remains a core cultural resource in social organization and political mobilization, and a vital conceptual resource in sociological analysis.
