The relevance of the researched problem is based on the need for working out an effective strategic management mechanism of sustainable development of enterprises, caused by current state of the global economy, which is characterized by high degree of instability. The aim of the article is to develop theoretical and methodological ideas of formation of the effective strategic management mechanism of sustainable development of enterprise. The leading approach of the research is the expert analysis, which allows to estimate the existing contradictions, to correlate the processes happening in the economy, and to reveal the tendencies promoting creation of conditions for sustainable development of enterprises. The results of the research: the features of strategic management of sustainable development of enterprises are revealed, setting of specific strategic aims and objectives are considered, identification of functional authority of realizers, methodological tools of implementation of this process, and also indication of specific subjects, realizing strategic managerial functions, and objects, on which managerial influence is reffered to. The practical relevance consists in improvement of the strategic management mechanism of sustainable development of enterprises, which is based on specification and expansion of definitions of strategic management of sustainable development, formation of the structure and ways of strategic managerial influence, increase in efficiency of procedures of the analysis of processes of sustainable development of enterprises. © 2016 Sherstneva, Vishnyakova and Chuchkalova

Organization of professional mobile practice for students - Future social educators

The relevance of the investigated problem is due to the increasing social tension in society and the state, associated with the active manifestation of anti-social phenomena and the need for prompt resolution of these problems through the involvement of professional mobile social educators. The purpose of the article is to develop a new concept in the organization and carrying out practices that promote the professional development of a new generation of social educators with such developed personal and professional qualities as professional mobility. The leading study method of this problem is the system that allows to integrate the scientific, theoretical and practical components of the implementation process of this new concept. The article describes the concept of the organization and conducting professional mobile practice, which is also graphically depicted as the structural-functional model of the development of professional mobility in the future social educators, consisting of interconnected target, informative, technological, control and evaluation components. Article can be useful for organizers of practical training of professional educational institutions. © 2016 Iskhakov et al

The Harish-Chandra isomorphism for reductive symmetric superpairs

We consider symmetric pairs of Lie superalgebras which are strongly reductive and of even type, and introduce a graded Harish-Chandra homomorphism. We prove that its image is a certain explicit filtered subalgebra of the Weyl invariants on a Cartan subspace whose associated graded is the image of Chevalley's restriction map on symmetric invariants. This generalises results of Harish-Chandra and V. Kac, M. Gorelik.Comment: 43 pages; v2: substantially improved versio

The economic efficiency of european football clubs - Data Envelopment Analysis (DEA) approach

The relevance of this paper lies in the fact that football business has grown significantly in the past 20 years and football clubs have become large companies, which in an effort to be profitable and successful on the field need to improve the efficiency of their business. The aim of this article is to measure economic efficiency of 48 big European football clubs and assess the relationship between efficiency and different financial and sportive indicators (variables). To measure efficiency, we used both widely used Data Envelopment Analysis (DEA) method and its extensions: DEA Super-efficiency and DEA Cross-efficiency models. The results showed that these methods can successively be applied to football clubs’ efficiency measurement and the analysis of the them can help to explain why some clubs are efficient or inefficient and which factors affects the efficiency. This paper will be interesting football clubs’ managers, football analytics, economists and other people interested in football business because we combine in it the most interesting ideas and methods about football clubs’ efficiency measurement. © 2016 Pyatunin et al

ОСОБЕННОСТИ КОМПЬЮТЕРНОЙ ТОМОГРАФИИ ТРУПА: ПРОБЛЕМА ИНТЕРПРЕТАЦИИ СПЕЦИФИЧЕСКИХ И НЕСПЕЦИФИЧЕСКИХ АРТЕФАКТОВ

The literature review analyzes studies on postmortem CT as an alternative to the conventional autopsy in forensic examination of the bodies of an adults. The main objective of the review is to give a brief analysis of the characteristics of post-mortem CT imaging, which do not face the clinical radiologists in their practice. The analysis comes up with 72 literature sources. The basic Internet resources were used during preparation of the study: Scientific Electronic Library (elibrary), SciVerse (ScienceDirect), Scopus, PubMed, and Discover. The review includes articles which discuss both the advantages and limitations of CT in the posthumous forensic examination of the bodies of an adults, and especially post-mortem CT imaging the most common pathological processes and artefacts. Conclusions. Early and late postmortem changes, such as rigor, autolysis, putrefaction and others largely change the normal pattern in CT imaging clinical radiologists are used to. In particular, the interpretation of CT images of the corpse must consider common specific and non-specific artefacts which result from: agonal changes (alteration in anatomical appearance, decomposition); autolysis, putrefaction; regurgitation of gastro-intestinal contents, aspiration; lividity and hypostasis; postmortem blood clotting; resuscitation effects; postmortem handling/autopsy technique; insect activity; and many others. These artefacts are not pathological findings, and should always be taken into account when interpreting the postmortem CT images.В обзоре литературы проанализированы исследования по проблеме посмертной компьютерной томографии (ПМКТ) в качестве альтернативы традиционному вскрытию в судебно-медицинской экспертизе трупов взрослых лиц. Основная цель обзора - дать краткий анализ особенностей посмертной КТ-визуализации, с которыми не сталкиваются клинические рентгенологи в своей практической деятельности. Представлен анализ 77 источников литературы. При подготовке обзора были использованы основные интернет-ресурсы: научная электронная библиотека (elibrary), SciVerse (ScienceDirect), Scopus, PubMed и Discover. В обзор включены статьи, в которых обсуждались как преимущества, так и ограничения ПМКТ в судебно-медицинской экспертизе трупов взрослых лиц, а также особенности посмертной КТ-визуализации наиболее часто встречающихся патологических процессов и артефактов. Выявлено, что ранние и поздние трупные изменения, такие как окоченение, аутолиз, гнилостные и другие посмертные процессы, в значительной степени меняют «норму» при КТ-визуализации к которой привыкли клинические рентгенологи. В частности, при интерпретации КТ-изображений трупа следует учитывать часто встречающиеся специфические и неспецифические артефакты, к которым приводят: свертки и седиментация крови в полостях сердца и крупных сосудах, посмертная аспирация содержимого желудка в воздухоносные пути, эзофаго- и гастромаляция, трупные пятна и гипостазы во внутренних органах, уплотнение стенок аорты, расширение правых отделов сердца, нарушение дифференцировки между серым и белым веществом головного мозга, гнилостные газы в сосудах, органах и тканях, и многие другие. Указанные артефакты не являются патологическими находками и должны быть обязательно учтены при интерпретации посмертных КТ-изображений

The gene normalization task in BioCreative III

BACKGROUND: We report the Gene Normalization (GN) challenge in BioCreative III where participating teams were asked to return a ranked list of identifiers of the genes detected in full-text articles. For training, 32 fully and 500 partially annotated articles were prepared. A total of 507 articles were selected as the test set. Due to the high annotation cost, it was not feasible to obtain gold-standard human annotations for all test articles. Instead, we developed an Expectation Maximization (EM) algorithm approach for choosing a small number of test articles for manual annotation that were most capable of differentiating team performance. Moreover, the same algorithm was subsequently used for inferring ground truth based solely on team submissions. We report team performance on both gold standard and inferred ground truth using a newly proposed metric called Threshold Average Precision (TAP-k). RESULTS: We received a total of 37 runs from 14 different teams for the task. When evaluated using the gold-standard annotations of the 50 articles, the highest TAP-k scores were 0.3297 (k=5), 0.3538 (k=10), and 0.3535 (k=20), respectively. Higher TAP-k scores of 0.4916 (k=5, 10, 20) were observed when evaluated using the inferred ground truth over the full test set. When combining team results using machine learning, the best composite system achieved TAP-k scores of 0.3707 (k=5), 0.4311 (k=10), and 0.4477 (k=20) on the gold standard, representing improvements of 12.4%, 21.8%, and 26.6% over the best team results, respectively. CONCLUSIONS: By using full text and being species non-specific, the GN task in BioCreative III has moved closer to a real literature curation task than similar tasks in the past and presents additional challenges for the text mining community, as revealed in the overall team results. By evaluating teams using the gold standard, we show that the EM algorithm allows team submissions to be differentiated while keeping the manual annotation effort feasible. Using the inferred ground truth we show measures of comparative performance between teams. Finally, by comparing team rankings on gold standard vs. inferred ground truth, we further demonstrate that the inferred ground truth is as effective as the gold standard for detecting good team performance

COMPLEX RADIOLOGICAL DIAGNOSIS OF COMPLICATED WILMS' TUMOR

Wilms' tumor is the most common primary malignant renal tumor. It is paradigm for comprehensive treatment of malignant solid tumors in children. Typically, children with this disorder are initially seen with abdominal distention, palpable masses or due to fever of unknown origin. Atypical tumor symptoms can be caused by complications, making it difficult to diagnose the disease. We present three clinical cases of Wilms' tumor in young children. Emergency multidetector computed tomography and magnetic resonance imaging provided the surgeon with sufficient information to perform an urgent radical resection
