In the last two decades, S and N critical loads have been used as indicators of ecosystem sustainability to soil acidification. The effect of acidification on the soil in forest ecosystems and their further development was the subject of numerous studies, based on which several mathematical models were developed. This paper presents the results of the analysis of acidification processes in brown podzolic soil on granodiorites in the stands of spruce and spruce and fir in the area of NP 'Kopaonik'. Critical loads of sulphur and nitrogen in these soils are presented using VSD model.

Let α be a limit ordinal with the property that any “recursive” function whose domain is a proper initial segment of α has its range bounded by α. α is then called admissible (in a sense to be made precise later) and a recursion theory can be developed on it (α-recursion theory) by providing the generalized notions of α-recursively enumerable, α-recursive and α-finite. Takeuti [12] was the first to study recursive functions of ordinals, the subject owing its further development to Kripke [7], Platek [8], Kreisel [6], and Sacks [9].Infinitary logic on the other hand (i.e., the study of languages which allow expressions of infinite length) was quite extensively studied by Scott [11], Tarski, Kreisel, Karp [5] and others. Kreisel suggested in the late '50's that these languages (even which allows countable expressions but only finite quantification) were too large and that one should only allow expressions which are, in some generalized sense, finite. This made the application of generalized recursion theory to the logic of infinitary languages appear natural. In 1967 Barwise [1] was the first to present a complete formalization of the restriction of to an admissible fragment (A a countable admissible set) and to prove that completeness and compactness hold for it. [2] is an excellent reference for a detailed exposition of admissible languages.

The subject of this research is the forecast or prediction of color. The Russian science does not feature work dedicated to such aspect; however, foreign sources approached prediction of color from various perspectives, most often viewing the color trends as an inseparable part of fashion. The goal of this work consists in determination of the place and time of conception of the color forecasts, historical analysis of evolution of this phenomenon, and assumptions on further development of this direction. Territorially, the epicenters of development of color forecasts are determined in Europe (France and England), in America (the United States), in Asia (Japan). The author describes the peculiarities of color predictions in each country – at certain stages one or another county was ahead or behind; whit the advent of the Internet, everything moves to online format and becomes more dynamic. The article follows the forecast of color since its emergence, highlighting all stages of its development and establishment. The chronological framework of its development stages stretches from the early XVIII century until modernity. From the earliest to more recent, these stages include the color cards, mediators and agents (between factories, textile workers and customers, and stores), trade fairs and expositions, online services and websites. It is determined that with the course of time, the methods and instruments for predicting color were being accumulated and used together; the new colors were added, while the already existing did not lose their relevance. Despite the development of technologies, a final word in forecasting color trends belongs to a human, based on experience and intuition.

The interdisciplinary character of the science of language causes great difficulties in bibliographic support in this field. The object of bibliographing in linguistics is not only literature on the language, but also a variety of linguistic resources, which represent a special object to study a branch of linguistics - lexicography. Bibliography of linguistics is the least studied field by specialists among humanitarian bibliographic complexes. The paper first studied the array of domestic bibliographic sources for more than 150 years; the most significant of them are shown. The subject of research is national bibliographic resources in the linguistics field. The objective is to characterize the historical development of the linguistic bibliography in Russia. To achieve this goal we had to solve a number of tasks: identify existing sources for ongoing historical research; to trace the history of forming bibliographic sources, bibliography of bibliographies of linguistics; to form and analyze the body of bibliographic materials; to characterize the problematic areas in the bibliographic software of linguistics. Using the bibliometric analysis it was studied an array of bibliographic products published between 1860 and 2013, the dynamics of bibliographic resources formation was determined, the degree of bibliographic support of some topics and issues in linguistic science and prior directions of their development were revealed. The main results of the study should be considered: 1. The nuclear of fundamental indices on general and applied linguistics is singled out in analyzed literature sources covering the period 1918-1977, as well as in Slavic linguistics for 1825-1981. The complex of current and retrospective bibliographic products was formed and replenished in the country in 1963-1988. 2. The largest share of bibliographic sources in linguistics is presented by book and article bibliography (over 70%), many of which remain bibliographically unrecorded and unused. 3. The following subject areas of linguistics are considered to be bibliographically supported: inter-linguistics, culture of speech and language norms, lexicography, linguistic geography, linguistics regional geography, onomastics. 4. An obvious need to continue the index or database of bibliographic aids in the field of linguistics over the past 50 years is marked. 5. Further development of the linguistics bibliography is impossible to imagine without creating an electronic guide on the bibliographic resources of linguistics, which would reflect the diversity of bibliographical resources and provide their rich information potential for professionals and remote users

Interactive Virtual Math (IVM) is a visualization tool to support secondary school students’ learning of graphs by dynamic events. In the prototype version students construct a graph and try to improve it themselves and with the feedback of the tool. In a small-scale experiment, which involved four classes at secondary and tertiary education and their mathematics teachers we investigated how the students used the tool in the classroom. In this study we focus on the students learning experience and the results are expected to provide knowledge and directions for further development of the tool. The corpus data consists of self-reported questionnaires and lessons observations. One main finding is that students, at different school levels, find the tool useful to construct or improve graphical representations and it can help to get a better understanding of the subject. The tool features that helped students most were the self-construction of the graphs and to get feedback about their own graph at the end. Other findings are that the students can work independently with the tool and we know more about the tool features that are attractive or need to be improved.

AbstractMisinformation in social media is an actual and contested policy problem given its outreach and the variety of stakeholders involved. In particular, increased social media use makes the spread of misinformation almost universal. Here we demonstrate a framework for evaluating tools for detecting misinformation using a preference elicitation approach, as well as an integrated decision analytic process for evaluating desirable features of systems for combatting misinformation. The framework was tested in three countries (Austria, Greece, and Sweden) with three groups of stakeholders (policymakers, journalists, and citizens). Multi-criteria decision analysis was the methodological basis for the research. The results showed that participants prioritised information regarding the actors behind the distribution of misinformation and tracing the life cycle of misinformative posts. Another important criterion was whether someone intended to delude others, which shows a preference for trust, accountability, and quality in, for instance, journalism. Also, how misinformation travels is important. However, all criteria that involved active contributions to dealing with misinformation were ranked low in importance, which shows that participants may not have felt personally involved enough in the subject or situation. The results also show differences in preferences for tools that are influenced by cultural background and that might be considered in the further development of tools.

The subject of this research is the death penalty as a mandatory punishment for the most serious crimes in the United States, Asia and the Caribbean and corresponding constitutional problems. The author analyses foreign courts’ judgments and foreign researchers’ points of view. The author considers the influence of the jurisprudence of the US Supreme Court on the countries with similar legal systems, the importance of legal thought in other countries for further development of law-enforcement practice in a particular region and the globalized world. The author analyzes inconsistent position of Singapore, as well as the indecisiveness of the government of Malaysia, because until recently these two countries were fervent supporters of the mandatory death penalty in the Commonwealth. The author supports the global trend towards the abolition of the mandatory death penalty and the fact that the “Asian values” are not an insurmountable barrier to achieve this goal.

Museums are a constantly developing segment of cultural tourism. Poland is in line with current trends in museums, expanding its offer and adapting it to the requirements of the world of contemporary image culture and multisensory experiences, which is increasingly dominated by technology. The authors of the paper undertook to recognise the specificity of military museums, by conducting a survey of approximately a third of all such institutions in Poland. Due to the subject-matter of their exhibitions, military museums create a broad field of research both in terms of aesthetics and museum practice, as well as the issues of shaping and maintaining collective memory and the identity of the nation. They form a special mirror in which the country’s ideas and aspirations are reflected more often than any real characteristics. In reference to contemporary trends in museums, the article aims to place Polish military museums between locality and universality, education and entertainment, stability and dynamism, knowledge and experience. The results obtained allowed the authors to distinguish three groups of military museums in Poland, as well as indicate conditions conducive to the further development of such attractions in the country.

This article is dedicated to examination of the traditional structure of the Russian institute of mediation and its possible transformations in light of the provisions of the new draft law “On Settlement of the Disputes Trough Mediation in the Russian Federation". Based on the principle of historicism and systemic analysis, the authors consider the established structure of the Institute, and highlight the three stages in development: latent, euphoria and stagnation. It is assumed that such peculiarities of development are substantiated by its implementation “from the top”. The current state of the institute of mediation, despite the fact that it remains at the “initial” level of development, can be characterizes as a years-long stagnation. Therefore, the draft of the new Federal Law on Mediation, developed by the Ministry of Justice, which in case of enactment significantly changes the structure and functional concept of mediation, became the subject of intense discussion within the professional community, since the intended radical reform is planned to be implemented “from the top”, without consideration of the opinion of professional community and interested stakeholders. Having analyzed separate elements of the institute of mediation and changes therein, the authors came to the following conclusions. One of the three key reasons for the established situation in the area of mediation is the low level of professional qualifications of mediators; incompetence of mediators impedes conducting mass mediation and further development of the institute of mediation. The second reason consists in incompetence and disunity of the professional community of mediators, absence of an authoritative body nationwide. The third reason lies in discrepancy of the development of two vectors of mediation — traditional and academic as a special trend in reconstructive approach. The presented analysis allows reassessing the current state and potential of the Russian Institute of mediation, as well as forecasting further ways of its development.

The virgin forests of the Ukrainian Carpathians are unique ecosystems in which preserved natural, protected, recreational, historical and cultural objects. That is why a comprehensive study of the forest ecosystems of the Ukrainian Carpathians is needed in order to preserve these unique treasures of our country. The Ukrainian Carpathians are characterized in ecological, educational and scientific-cognitive aspects, as a significant number of objects and monuments of nature, history, architecture and culture are concentrated here. In the region under study, there is a well-developed network of nature reserve fund, the objects of which are basic for the organization of tourist activity. The importance of virgin forests as an ecological-educational and scientific-cognitive object of the Ukrainian Carpathians is revealed. The purpose of the research was to study the forests of the Ukrainian Carpathians, as an object of ecological, educational and cognitive perception. The object of the research was the forest ecosystems within the conservation areas of the Ukrainian Carpathians. The subject of the study was the consideration of forest ecosystems as an ecological-educational and scientific-cognitive object. To achieve this goal, the following tasks were set: to give a complete definition of the term “primaeval” forests and their varieties; to identify, establish distribution areas and forest areas in the Ukrainian Carpathians; to analyze their ecological-educational and scientific-cognitive functions. It is revealed that the centres of distribution of forest ecosystems in the Ukrainian Carpathians are nature conservation areas, namely: Carpathian Biosphere Reserve, Carpathian National Park, Uzhansky, Synevyr Verkhovyna, Cheremosky, Hutsulshchyna, Vyzhnytsya, Zacharovanyi Krai. It is stated that ecological-educational and scientific-cognitive objects in the region are natural undisturbed by the anthropogenic activity of the place. The best network of ecological-educational and scientific-educational trails is set up in the Carpathian Biosphere Reserve. The most popular are the eco-routes “To Goverla Mountain from Lazeshchyna”, “Kevelsky Forests to Petros”, “Beech Forests of Velyka Ugolka”, “To Sokolino Berdo”. It is revealed that the ecological-educational and scientific-cognitive potential of the forests of the Ukrainian Carpathians is special. The primaeval forests are widespread in the Ukrainian Carpathians, and their area is about 50 thousand hectares, and much of it requires identification. Forests have a special status in Ukraine and are strictly protected in nature reserves and perform ecological-educational and scientific-cognitive functions, since within them preserved natural, intact, virgin objects and also represent the cultural heritage of the region. Key words: Ukrainian Carpathians, virgin forests, quasi-virgin forests, ancient forests, ecological-educational and scientific-cognitive objects.

Введение: Вопрос о дальнейшем совершенствовании базисной терапии иммунной тромбоцитопении (ИТП) по-прежнему широко обсуждается специалистами и является предметом оживленных дискуссий. Цель исследования: оценить эффективность высокогорной климатотерапии при хронической ИТП у детей за 5-летний период наблюдения после ежегодного лечения на высокогорной базе. Материалы и методы: В исследование включено 22 ребенка с хронической ИТП в возрасте от 3 до 14 лет, средний возраст — 6,30 ± 1,02 года, длительность заболевания 2-8 лет. Для лечения детей поднимали на высокогорную базу. Продолжительность лечения в высокогорье составляла 40 дней. Результаты: Из 22 детей, получивших 5 курсов высокогорной климатотерапии, у двоих наблюдали полную ремиссию в виде увеличения тромбоцитов более 100×109/л без кровоточивости. Объективный ответ в виде двукратного увеличения числа тромбоцитов, но менее 100×109/л без кровоточивости установлен у 18 детей, отсутствие эффекта было зарегистрировано у 2 детей. Заключение: Повторные курсы высокогорной климатотерапии способствуют улучшению клинической картины, существенному повышению числа тромбоцитов в периферической крови и достижению ремиссии при ИТП у детей. Background: Further development of basic treatment of immune thrombocytopenia (ITP) is still widely discussed by specialists and is the subject of lively discussions. Objectives: to assess the effi ciency of high-altitude climatotherapy in children with chronic ITP for a 5-year follow-up period after annual treatment at high-altitude base. Patients/Methods: The study included 22 children with chronic ITP from 3 to 14 years, the average age was 6.30 ± 1.02 years, and disease duration was 3-8 years. Children were raised to high-altitude base. Treatment duration was 40 days. Results: 22 children received 5 courses of high-altitude climatotherapy. Complete remission was observed in 2 patients with increasing of platelets more than 100×109/L without bleeding. In 18 children an objective response was found in the form of twofold increasing of platelets number, but less than 100×109/L without bleeding; no effect was recorded in 2 children. Conclusions: Repeated courses of high-altitude climatotherapy improve clinical characteristics, significantly increase the number of platelets in the peripheral blood and contribute to remission in children with ITP.
