Speech Portrait at the Russian Language Lesson in the 8th Grade of Secondary School

Characterization of a person through their speech in the cognitive, social, psychological and cultural terms is one of the important trends in modern linguistics. The scope of research includes descrip­tive texts about linguists. The attention to speech analysis is associated with the problem of the students' poor ability to analyze details and to create a speech portrait of a person. The purpose of this study is to analyze the materials of the 8th grade Russian language textbook which acquaint pupils with the concepts of "speech portrait" and "characterization of a person" and form the students' skills of analysis and charac­terization. The author of the article compares different points of view of Russian scholars on the concepts of "linguistic personality" and "speech portrait". The article provides an overview of exercises that form the analytic skills of personal characterization. The author recommends conducting a comprehensive analysis of the personality of a scholar based on the texts given in the textbook.В статье на материале учебника рассматривается формирование у обу­чающихся навыков составления характеристики личности

Recent developments in time-of-flight PET

While the first time-of-flight (TOF)-positron emission tomography (PET) systems were already built in the early 1980s, limited clinical studies were acquired on these scanners. PET was still a research tool, and the available TOF-PET systems were experimental. Due to a combination of low stopping power and limited spatial resolution (caused by limited light output of the scintillators), these systems could not compete with bismuth germanate (BGO)-based PET scanners. Developments on TOF system were limited for about a decade but started again around 2000. The combination of fast photomultipliers, scintillators with high density, modern electronics, and faster computing power for image reconstruction have made it possible to introduce this principle in clinical TOF-PET systems. This paper reviews recent developments in system design, image reconstruction, corrections, and the potential in new applications for TOF-PET. After explaining the basic principles of time-of-flight, the difficulties in detector technology and electronics to obtain a good and stable timing resolution are shortly explained. The available clinical systems and prototypes under development are described in detail. The development of this type of PET scanner also requires modified image reconstruction with accurate modeling and correction methods. The additional dimension introduced by the time difference motivates a shift from sinogram- to listmode-based reconstruction. This reconstruction is however rather slow and therefore rebinning techniques specific for TOF data have been proposed. The main motivation for TOF-PET remains the large potential for image quality improvement and more accurate quantification for a given number of counts. The gain is related to the ratio of object size and spatial extent of the TOF kernel and is therefore particularly relevant for heavy patients, where image quality degrades significantly due to increased attenuation (low counts) and high scatter fractions. The original calculations for the gain were based on analytical methods. Recent publications for iterative reconstruction have shown that it is difficult to quantify TOF gain into one factor. The gain depends on the measured distribution, the location within the object, and the count rate. In a clinical situation, the gain can be used to either increase the standardized uptake value (SUV) or reduce the image acquisition time or administered dose. The localized nature of the TOF kernel makes it possible to utilize local tomography reconstruction or to separate emission from transmission data. The introduction of TOF also improves the joint estimation of transmission and emission images from emission data only. TOF is also interesting for new applications of PET-like isotopes with low branching ratio for positron fraction. The local nature also reduces the need for fine angular sampling, which makes TOF interesting for limited angle situations like breast PET and online dose imaging in proton or hadron therapy. The aim of this review is to introduce the reader in an educational way into the topic of TOF-PET and to give an overview of the benefits and new opportunities in using this additional information

Image of Presenter of Political Talk Show: on Problem of Gender Peculiarities

The study is done within actual direction of modern science - the gender linguistics. The article is devoted to the question of the communicative image of the TV presenters of political talk-show Vladimir Solovyov and Olga Skabeyeva. The results of a comparative analysis of the components of the public image of each media person are presented: appearance, communicative behavior, speech manners. It is shown that Solovyov and Skabeyeva have a bright, catchy, wistful image, and their similarities - leading position, business style in clothes, gestures system, categoricalness - are determined by the program format. It is proved that at the same time, communicative images of the presenters have a specific gender identity: Vladimir Solovyov’s image corresponds to stereotypical idea of a real man, while Olga Skabeyeva’s image combines both typically female (modesty, elegance, parity) and male characteristics (rationality, rigidity, hardness). Special attention is given to verbal behaviour that detects the individual characteristics of each media person. Vladimir Solovyov’s manner of speech can be characterized as assertive, poly-stylistic, management one. The authors argue that the dominant for this presenter is a strategy of self-presentation, while the main intention can be defined as the retention of communicative leadership. The general speech style of Olga Skabeyeva can be described as aggressive, but the presenter purely uses female methods of mitigating the conflict. It is proved that the communicative style of the presenter is not free from gender peculiarities of the personality

Instruments of Innovation Security

This paper sets out a scientific debate on the phenomenon of innovation security and regional innovation security in particular. Authors suggest that innovation security should be considered as an independent type of regional security, along with economic, environmental, political, etc. security types. It is assumed that innovation security is one of the key imperatives of regional development along with the sustainability, competitiveness, and innovativeness. Article rests upon the analysis of the mechanisms and tools within the innovation policies of the highly innovative countries of the Baltic region – Denmark, Finland, Germany, Norway, and Sweden, which demonstrate an ‘unintended' application experience of the regional innovation security provision. The study underlines the most influential factors affecting the institutional framework of an innovation security establishment process. Paper concludes with a set of policy recommendations on regional innovation security in the context of contemporary socio-economic trends. Keywords: innovation security, innovation policy, innovation potential, region, Baltic region, BSR, Germany, Nordic countries, Russia, international cooperation JEL Classifications: D83; D85; F52; O3

In systemic sclerosis, anxiety and depression assessed by hospital anxiety depression scale are independently associated with disability and psychological factors.

Background. Anxious and depressive symptoms are frequent in Systemic Sclerosis (SSc). Our objective is to assess their prevalence and association with district and global disability and psychological variables. Methods. 119 SSc patients were assessed by Hospital Anxiety Depression Scale (HADS). Clinical depression and anxiety were defined for HADS score cutoff ≥8. Patients were assessed for psychological symptoms (RSES, COPE-NIV), hand (HAMIS, CHFDS, fist closure, and hand opening) and face disability (MHISS, mouth opening), global disability, and fatigue (HAQ, FACIT). Results. Both depression and anxiety in SSc are 36%. Depressive patients with comorbid anxiety have higher HADS-D score than patients with depression only (). HADS-A and -D are positively correlated with global disability, hands and mouth disability, fatigue, self-esteem and avoidance coping strategy, and, only HADS-A, also with social support (). By multiple regression, HADS-D is independently associated with FACIT-F (), RSES (), and MHISS total score (), together explaining 50% of variance. HADS-A is independently associated with RSES (), COPE-NIV SA (), COPE-NIV SS (), FACIT-F (), and MHISS mouth opening (), explaining 41% of variance. Conclusions. In SSc depression and anxiety correlate to local and global disabilities and psychological characteristics. Depressive patients with comorbid anxiety have higher level of depressive symptoms
