Subject. This article deals with the issues relating to improving integrated reporting in terms of dovetailing strategic objectives with capital changes. Objectives. The article aims to develop a system of indicators for disclosure of capital types in integrated reporting of electricity generating companies, as well as recommendations aimed at implementing the fundamental concepts and guiding principles of integrated reporting. Methods. For the study, we used the methods of analysis and synthesis, comparison, generalization, and abstraction. As a case study, we conduct a comparative analysis of the disclosure of six types of capital by the largest electricity generating companies, namely PAO Inter RAO, AO Rosenergoatom and PAO RusHydro. Results. The article formulates proposals for disclosure of capital information to address such a lack of accountability as a contradiction to the principle of coherence. It proposes a system of indicators (core and additional) for disclosure of six types of capital by electricity generating companies. Conclusions. A significant reporting problem is the lack of correlation between key strategic objectives and capital changes. The formulated recommendations for disclosure of capital information can help solve this problem, and increase the attractiveness of the integrated report for capital providers.

Abstract Synthesis has become ubiquitous in ecology. Despite its widespread application to a broad range of research topics, it remains unclear how synthesis has affected the discipline. Using a case study of publications (n = 2304) from the National Center for Ecological Analysis and Synthesis compared with papers with similar keywords from the Web of Science (n = 320,000), we address several questions about the comparative impact of synthesis, the role of synthesis in driving key research themes, and whether synthesis is focused on different topics than is the broader ecological literature. We found much higher citation rates for synthesis papers overall (fivefold more) and within eleven key topic themes (e.g., species richness, biodiversity, climate change, global change). Synthesis papers often played key roles in driving, redirecting, or resolving core questions and exhibited much greater cross-theme connectivity. Together, these results indicate that synthesis in science has played a crucial role in accelerating and advancing ecological knowledge.

An alternative method to analyze a class of nonlinear systems in a bond graph approach is proposed. It is well known that the analysis and synthesis of nonlinear systems is not a simple task. Hence, a first step can be to linearize this nonlinear system on an operation point. A methodology to obtain linearization for consecutive points along a trajectory in the physical domain is proposed. This type of linearization determines a group of linearized systems, which is an approximation close enough to original nonlinear dynamic and in this paper is called dynamic linearization. Dynamic linearization through a lemma and a procedure is established. Therefore, linearized bond graph models can be considered symmetric with respect to nonlinear system models. The proposed methodology is applied to a DC motor as a case study. In order to show the effectiveness of the dynamic linearization, simulation results are shown.

Abstract A fatal accident occurred when a right angle gear box on an auger elevator disintegrated freeing the outboard end of a rotating PTO shaft. The tractor, acting as a stationary power source, flailed the PTO shaft which then struck and killed a farmer. No similar occurrences have been reported for the nearly 2000 similar units which have been used for over a decade. This paper studies a number of fundamental failure modes in order to determine which failure modes created the accident. Systematic analysis showed that the accident was caused by unusual misuse of the product. Known safety control concepts do not preclude this unforeseeable event.

This paper investigates adjectival agreement in a group of Middle Welsh native prose texts and a sample of translations from around the end of the Middle Welsh period and the beginning of the Early Modern period. It presents a new methodology, employing tagged historical corpora allowing for consistent linguistic comparison. The adjectival agreement case study tests a hypothesis regarding position and function of adjectives in Middle Welsh, as well as specific semantic groups of adjectives, such as colours or related modifiers. The systematic analysis using an annotated corpus reveals that there are interesting differences between native and translated texts, as well as between individual texts. However, zooming in on our adjectival agreement case study, we conclude that these differences do not correspond to many of our hypotheses or assumptions about how certain texts group together. In particular, no clear split into native and translated texts emerged between the texts in our corpus. This paper thus shows interesting results for both (historical) linguists, especially those working on agreement, and scholars of medieval Celtic philology and translation texts.

Currently, there are many points of view on management of physiological labor, in particular, it concerns the intrapartum position of a woman. Tactics of modern obstetrics should ensure the safety of motherhood, which in future ensures the prosperity of the state. One of the alternative methods of delivery is the vertical position of a woman in the intrapartum period. It is impossible to describe the whole range of possible positions of a woman in the intrapartum period, the common ones being: lying position (lateral, reclining, lithotomy, Trendelenburg’s, etc.) or upright position (sitting, using a chair for childbirth, standing, squatting, standing on the knees, etc.). Opinions about how the vertical position of a mother in the intrapartum period affects the outcome of childbirth are quite ambiguous. The conclusions of various authors on that matter often contradict each other.The aim of the research was to study the role of vertical delivery in reducing the frequency of obstetric and perinatal complications.Materials: publications of foreign and domestic authors within the period from 1989 to 2017.Methods: systematic analysis and synthesis of literature data.Conclusion: Despite a significant number of studies, it is not possible to determine the universality of the vertical position in childbirth, therefore, the selection of patients for the management of vertical childbirth should be approached carefully. In the presence of pregnancy complications, preference should be given to the classic version of the position in childbirth. In women who have a low risk of perinatal complications, an upright position can be a worthy alternative. To prevent the development of bleeding in the III stage of labor and the early postpartum period, a woman should take a horizontal position after the birth of the fetus. This condition must also be observed when examining the birth canal. Thus, the rational tactics of conducting childbirth is to determine the optimal combination of vertical and horizontal positions at different periods of the childbirth process, taking into account the convenience for the woman in labor.

The aim of the article. Based on a comprehensive analysis of archives, published documents, and materials, as well as current historical studies, the phenomenon of mass child homelessness in Ukraine during the Holodomor-Genocide which organized by the Russian communist regime in 1932–1933s is highlighted. The aim of the article is to analyze the activities of state authorities and their commissions in assisting homeless children in the process of overcoming this tragic social phenomenon. The research methodology is based on a combination of general scientific (analysis and synthesis), special and historical (problem-chronological, historical-systematic) methods and principles of scientificity and historicism. The scientific novelty of the study lies in the fact that the author first attempted a systematic analysis of the mass child homelessness and death caused by the authorities for the first time in the history of Ukraine during the Holodomor-Genocide. Conclusions. We can state that almost all of the activities of state authorities to overcome mass starvation and homelessness of children and adolescents during the Holodomor-Genocide of 1932–1933s consisted in overcoming street homelessness as a social phenomenon by removing children from the streets, placing them in unsuitable premises due to a lack of residential care facilities, returning them to families or placing them under collective and individual foster care. Such measures only partially served to improve the situation of a tiny proportion of children, but could not address the issue fundamentally, since it was not a primary concern of the Stalin’s regime itself. After all, the main reason for the growth of homelessness was the mass starvation of the Ukrainian peasants caused by his anti-human policy of liquidating the Ukrainian peasantry through mass repression and terror and plundering food by the so-called “dekulakization”, which implied the physical destruction of the peasant and his descendants and further enslavement of those who remained, and driving them into collective farms.
