BACKGROUND: No studies so far have investigated the effectiveness of the short-term intervention on the capacity of the ISP during throwing motion in baseball player with throwing disorder. OBJECTIVE: To investigate the effectiveness of short-term intervention on ISP during throwing motion and of physical examination in baseball player with throwing disorder. METHODS: Twenty-seven male baseball players with throwing disorder were hospitalized for 1 week and received physical therapy for 1 hour a day. In the pre- and post-hospitalized period, participants were evaluated using physical examinations (Hara test) and ISP and posterior deltoid muscle activity during throwing motion. RESULTS: The ISP during the late-cocking phase and follow-through phase at the time of hospital discharge were significantly greater than that at the hospital admission ([Formula: see text] 0.05). The effect sizes revealed large effects for follow through phase ([Formula: see text]0.60). The positive rate of the Hara test decreased significantly in all examination items except scapula-spine distance, subacromial impingement test, and hyper-external rotation test. CONCLUSIONS: The ISP in throwing motion is important to the stability of the glenohumeral joint during follow-through phase. Our results indicated that the improvements in the physical examination reflected favorably on the ISP during the throwing motion.
Temporal gene expression changes after acute and delayed ventral root avulsion-reimplantation
Authors: Günther Mattias , Sköld Mattias K. 
Published: October 2019

Background: In a model of injured spinal motor neurons where the avulsed spinal nerve is surgically reimplanted, useful regrowth of the injured nerve follows, both in animal experiments and clinical cases. This has led to surgical reimplantation strategies with subsequent partial functional motoric recovery. Still, the ideal time point for successful regeneration after reimplantation and the specific genetic profile of this time point is not known. Objective: To explore the temporal gene expression of the whole genome in the ventral spinal cord after reimplantation at different time points after avulsion. Methods: Totally 18 adult rats were subjected to avulsion of the left L5 root only (N = 3), avulsion followed by acute spinal reimplantation (N = 3), avulsion followed by 24 h (N = 3) or 48 h (N = 3) delayed reimplantation. Animals were allowed to survive 24 h after their respective surgery whereafter the ventral quadrant of the spinal cord at the operated side was harvested, processed for and analysed with Affymetrix Rat Gene ST 1.0 array followed by statistical analysis of gene expression patterns Results: Specific gene expression patterns were found at different time points after avulsion and reimplantation. Over all, early reimplantation seemed to diminish inflammatory response and support gene regulation related to neuronal activity compared to avulsion only or delayed reimplantation. In addition did gene activity after avulsion-reimplantation correspond to regeneration-associated genes typical for regeneration in the peripheral nervous system. Conclusions: Our study reveal that genetic profiling after this kind of injury is possible, that specific and distinct expression patterns can be found with early reimplantation being favourable over late and that regenerative activity in this kind of injury bears hallmark typical for peripheral nerve regeneration. These findings can be useful in elucidating specific genetic expression typical for successful nerve regeneration, hopefully not only in this specific model but in the nervous system in general.
Different data futures: An experiment in citizen data
Authors: Ruppert Evelyn 
Published: October 2019

Big data and citizens are inseparable: from smartphones, meters, fridges and cars to internet platforms, the data of most digital technologies is the data of citizens. In addition to raising political and ethical issues of privacy, confidentiality and data protection, the repurposing of big data calls for rethinking relations to citizens in the production of official statistics if they are to be trusted. I argue for relations that involve co-producing data – or ‘citizen data’ – where citizens are engaged in statistical production, from the design of a data production platform to the interpretation and analysis of data. While raising issues such as data quality, I suggest that in a time of ‘alternative facts’, what constitutes legitimate knowledge and expertise are major political sites of contention and struggle and require going beyond defending existing practices towards inventing new ones. In this light, the future of official statistics not only depends on inventing new data sources and methods but also mobilizing the possibilities of digital technologies to establish new relations with citizens.
WAYS TO REDUCE THE RISK OF OCCURRENCE OF ENVIRONMENTAL ORIGIN EMERGENCY SITUATIONS IN AREAS OF ANTHROPOGENIC IMPACT AT COAL MINES
Authors: Karabyn V. 
Published: October 2019

The description of the topic and problems of the object. The factors of environmental danger that can lead to emergency situations in areas of technogenic impact of mining enterprises in the Lviv-Volyn coal basin are analyzed.
The purpose of the article is to justify the feasibility of the measures to minimize the spread of pollutants from mine dumps by the arrangement of geochemical barriers.
The results of the research. The microelement composition of the dumps rocks of some mines in the coal basin have been examined. The rocks of mine waste heaps Chervonograd in compareness with the clark for clays and mudstone rocks of waste heaps concentrate Cobalt, Lead, Magnesium, Yitrium, Cuprum, Itterbium and Beryllium; Nadiia – Gallium, Manhan, Plumbum, Stanum, Itterbium, Cuprum; Stepova – Titanium and Tsirconium; Mezhyrichanska – Molybdenum and Plumbum. By the principal component methodparagenetic associations of trace elements and environmental parameters, which gave the opportunity to predict the ways and forms the main components of migration of trace element contamination are dedicated. In particular, for the rocks of mine waste heaps at Stepova such paragenetic associations are allocated: 1) the thickness of the bulk layer, the swiftness of slope, the ash content of rocks, the concentration of Sn, Cr, Zn and mudstones; thecontent of coal, pyrite, siderite, siltstone, Co, Ni, Mo, Cu, geomorphological characteristics, radioactivity of rocks; 2) the concentration of Pb, Ti, Cu, Sr, mudstone and rocks; 3) the contents of Mn and P. For the rocks of mine Mezhyrichanska are shown the association: 1) content of V, Y, Yb, Co, Ti, P, Cr, Ni, Be, Mn, Cu, Ba, Sn, Sc, Zn, Ga, Sr, Zr, ash content of rocks 2) the content of Mo, distribution of coal, not burnt rocks and pyrite. For the environment protection from pollution the most optimal methods are based on acceleration of the natural transformation of pollutants in the secure or their targeted concentrations in some limited areas with an area of the lithosphere, which are declared. To reduce the level of environmental risk and minimize the occurrence of emergency, on the territory of the Lviv-Volyn coal basin, the arrangement of artificial geochemical barriers on the way of pollutants from coal mine waste dumps to water have been proved for the first time.
From the Proverbs to Modern Media. Formation of People Identity Through Education of Language Stereotypes of Neighbors
Authors: Jacewicz I. 
Published: October 2019

Introduction. The paper deals with the phenomenon of language as a marker of people's identity, which is formed by building boundaries and describing relationships, primarily between neighbors. The aim of the research work is to analyze the forms of expression of journalists in the media.Methodology and sources. The report examines materials from the main release of the News of the first Polish television channel, concerning the two neighbors of the Poles, that is, the Germans and Russians. The collected material covers the period of November 16, 2015, that is, from the day of the inauguration of the new Polish government (which has a completely different approach to Poland’s foreign affairs than its predecessors) until December 31, 2016. Created and described on the basis of the collected material stereotypes of German and Russian in modern Poland will be compared with the stereotypes of these two peoples, familiar to Poles by proverbs, which were found in the explanatory dictionaries of the Polish language, as well as in other dictionaries of proverbs and sayings. The linguistic analysis of the text, the socio-psychological-linguistic foundations of the formation of auto-and heterostereotypes, mass-media discourse and its impact on recipients were used as the theoretical basis for the arguments presented in the paper.Results and discussion. In Polish dictionaries, and dictionaries of Proverbs and sayings it was found 38 Proverbs Russian Proverbs and 107 of the Germans. It was analyzed how many of them are positive and how many negative traits of Russians and Germans. As for the Russian, positive traits can be found in only 6 of 38 Proverbs (15.7 percent). There are 18 positive of 107 sayings about Germans in Polish sources (16.8 percent). Specified number of Proverbs shows that the poles hand down from generation to generation a negative image of their neighbors. On the basis of material collected from "News" channel images of Russians and Germans were made up as well. During the period under review, any positive information about Russia and Russian has not appeared. As for the Germans, it is also dominated by a negative image, and, if to speak about positive things, they are never left without comment, which contains a warning.Conclusion. Heterostereotypes play an active role in fostering the way of thinking of contemporaries and, one can assume, representatives of the next generations, since popular wisdom and historical experience are passed on from generation to generation in each country. Heterostereotypes often become reality themselves, are inherited and acquire new symbolic meanings, and are updated depending on the political situation. A comparison of the heterostereotypes of Russian and German in Polish proverbs, the oldest of which were found in a dictionary published in 1830, with modern heterostereotypes from the main release of “News” proves that the description of the phenomenon of stereotypes in each new historical era is an important scientific problem.
Consequences of IT Transformations
Authors: Gutorovich O. V. , Gutorovich V. N. 
Published: October 2019

Introduction. The driving force of the modern society development is information technology transformations. They determined the beginning of qualitative transformations of not only the world order, but also many essential features of the state. Because of this, the study of changes in the sphere of political power and government, as well as the class structure of society, acquires special significance.Methodology and sources. The conclusions presented in this paper are based on the methodology of analytical and critical generalization in the field of social philosophy, as well as special theories and approaches, among which should be noted the neoinstitutional approach, the theories of the post-industrial and network society.Results and discussion. The introduction of digital technology is stacked for the state in two ways. The state receives not only new mechanisms for monitoring, accounting, control, pressure, and verification of the population, but also a high degree of citizen involvement in the state governing process. The consequence of a high degree of activity of civil structures may be the decentralization of state power and the redistribution of powers. A significant danger to the state is the network governing structure that requires all its participants to connect to the information channels. Having taken root in the governing environment, the network principle will come into conflict with the traditional chain of command, which will inevitably lead to the dispersion of its functions and blur the old governing schemes. There are the formation and further confrontation of two classes, which can be conventionally called the "higher" and "lower" classes in the logic of the development of the modern information society. Thus, in the course of the study, the problem of the transformation of the state institution in the conditions of information technology transformations was analyzed, and the issue of the formation of a new class structure was also raised.Conclusion. The age of information technology does not just create a new society, but it determines its essence, structure, basic characteristics, determines and sets parameters of its development.
