Abstract Advances in computer power, new forecasting challenges, and new diagnostic techniques have brought about changes in the way atmospheric development and vertical motion are diagnosed in an operational setting. Many of these changes, such as improved model skill, model resolution, and ensemble forecasting, have arguably been detrimental to the ability of forecasters to understand and respond to the evolving atmosphere. The use of nondivergent wind in place of geostrophic wind would be a step in the right direction, but the advantages of potential vorticity suggest that its widespread adoption as a diagnostic tool on the west side of the Atlantic is overdue. Ertel potential vorticity (PV), when scaled to be compatible with pseudopotential vorticity, is generally similar to pseudopotential vorticity, so forecasters accustomed to quasigeostrophic reasoning through the height tendency equation can transfer some of their intuition into the Ertel-PV framework. Indeed, many of the differences between pseudopotential vorticity and Ertel potential vorticity are consequences of the choice of definition of quasigeostrophic PV and are not fundamental to the quasigeostrophic system. Thus, at its core, PV thinking is consistent with commonly used quasigeostrophic diagnostic techniques.

AbstractBackground: Disagreement currently exists regarding the definition of aortic dextroposition. It is suggested that the term be used interchangeably with aortic overriding, along with suggestions that the aortic valve overrides in the normal heart. The dextroposed aorta, however, does not always override the crest of the muscular ventricular septum. It is incorrect to argue that the normal aortic valve overrides. It is the cavity of the right aortic valvar sinus, rather than the valvar orifice, that sits above the muscular septum when the septum itself is intact. Therefore, to circumvent these difficulties, those using the term “dextroposition” find it necessary to distinguish “true” as opposed to “false” categories. The problems arise because “dextroposition” is remarkably ill-suited as an alternative term for aortic valvar overriding.Methods and Results:In this review, combining developmental, morphologic, and clinical data, we show how aortic overriding is best considered on the basis of biventricular connection of the aortic root in the setting of deficient ventricular septation. When analysed in this manner, it becomes an easy matter to distinguish between one-to-one and double outlet ventriculo-arterial connections. Appreciation of these features emphasises the different spatial alignments of interventricular communications as opposed to the plane of deficient ventricular septation. The concept of overriding is applicable not only to biventricular connection of the aortic root, but also the pulmonary and common arterial roots.Conclusions:The diagnostic techniques now available to the paediatric cardiologist illustrate the features of arterial valvar overriding with exquisite accuracy, informing the discussions now required for optimal decision making.

This monograph reveals the conservative essence of the Black Hundred movement and its ideology aimed at the protection of Christian and national traditions in Russia in 1905-1917. This task is solved on the basis of an analysis of the origins, foundations of the theoretical constructs and programs of the extreme right monarchist parties in comparison with the system of views of Russian nationalists. The subjects for consideration are a set of basic ideological principles, postulates and provisions of ideologies of the Black Hundred organizations; the Orthodox religious foundations of the right monarchist ideology; conservative bases of political problematics and the problem of "Russia – the West"; approaches to the definition of nation (nationality); Imperial and national perspectives; the role and place of the Russian people; attitudes to pogroms and terrorist methods of struggle. The research proposes a system of criteria for the identification of party and personal affiliation to the Black Hundred spectrum in Russia the early 20th century, allowing a clear border to be drawn with nationalist (including fascist) parties. The urgency for this research has been caused by a poor development in the historiography. Intended for historians, sociologists, political scientists.

The article is devoted to the 250th anniversary of the Ukrainian rebellion, known as the «Koliivshchyna». The most significant burst of this uprising took place in the late 60’s of the XVIII century. The reason for the dissatisfaction of the people was the merciless exploitation of the Ukrainian peasantry by the Polish invaders. The Polish exploitation was carried out on the basis of social origin, nationality and religious confession. The most significant events connected with the above rebellion took place in Uman and its surroundings in 1768. The fight of the rebels was tough and bloody, obviously this particular feature of the rebellion called «Koliivshchyna» (from the word «koloty» – to thrust). The author of the article notes that for 250 years, separating us from the apogee of the rebellion, the accumulation of primary historical materials had to be completed, on the basis of which historians would have to determine the way of interpretation and to conduct a moral and legal evaluation of the events associated with the uprising. But we must admit that this is not the case. The reasons for this situation are sought by the author in an inadequate application of the Western historians’ achievements.The author takes into account the spirit of the uncertainty of positions in the way of treating the events associated with the rebellion in many publications of contemporary media, and this gives the right to conclude that there exists a problem of unity in the way of interpreting the purpose of the uprising and the actions of the rebels. The author sees the reason for this situation in the fact that Ukrainian historical experts in the historical studies of the above mentioned events connected with the «Koliivshchyna» rebellion, do not sufficiently apply the intellectual achievements of the historic school «New Historians», well known in the West (this school is also called the «Annales» school, the founders the schools are Mark Bloch and Lucien Febvre). The researchers also ignore the contemporary critique of the paradigms of Leopold von Ranke «Objectivist School». The achievements of famous Western epistemologists, such as Allan Megill, also fail to achieve optimum effect. The author points out the advantages of the «New Historians» School in constructing the results of historical research, but, on the background of the advantages and achievements of Western historians, the author of the proposed article proves the benefits of studies of Ukrainian historians.The widespread use in Western historical research the works of the New Historians School supporters has had a significant positive impact on the development of the historical science of these countries. The application of the scientific development of the supporters of this school (the school «New Historians» arose in 1929) was the reason for a qualitative step in the process of historical research in the West. In Ukraine, the widespread use in studies related to historical science subjects such as oral history, history of concepts, bottom history, visual history and many other related subjects of great popularity have not yet gained popularity, although some successes can already be seen.In the article the author provides the achievements of Ukrainian historian, professor Vasyl Shevchuk, which he gained during the study of the history of Ukrainian statehood, as an example of the successful development of the latest approaches to the study of Ukrainian history. V. Shevchuk in the early 90’s of the twentieth century became the founder of the definition of the statehood characteristics, which become apparent after the first victories of the rebels. According to V. Shevchuk, there are eight such characteristics. The process of acquiring statehood characteristics during the uprising usually occurs in the process of achievement by the rebels the success in the fight against the oppressors. So, the expansion of the tools of the study of the Ukrainian history related to historical subjects, such as that introduced by the school «New Historians», will definitely expand the possibilities for interpreting the events that took place during the uprising in 1768. At the very least, the use of the latest methods of studying the history of Ukraine gives such an opportunity to the researcher.New methods of studying the history of Ukraine, successfully used by the Ukrainian historians, will surely lead to an understanding and tolerant attitude to the fact that the history of Ukraine will not be perceived by Ukrainian in the same way as by a Pole or Russian, or anyone else with a distinct national identity. National systems of traditions, customs, peculiarities of the mentality and many other factors are the obstacle that will never let the Pope and the German or the Pole and Ukrainian perceive the truth of the story with the same emotions. The text of the article proved the existence of a problem of interpretation of the purpose and issues of the «Koliivshchyna» rebellion. The solution to this problem will take place in any case. To do this, you only need to perceive historical events with a sense of mutual respect and avoid single-ended estimates and uncompromising attitude.

The relevance of the interpretation of constitutional and legal guarantees of the right to vote is mediated by isolated scientific research in this area, as well as the lack of a universal approach to legal guarantees. In this regard, the purpose of the article is to argue and disclose the author’s definitive aspect of the claimed guarantees. In the work, the author named and characterized the normative (based exclusively on legal means) with the perspective of a branch of legal and technical; regulatory and institutional (combines the formal aspect with the activities of authorized entities) and associated legal (including a set of legal and other aspects) approaches to the definition of legal guarantees. Based on the second approach, as well as combining the guarantees of the right to vote directly guarantees of the subjective right itself and guarantees of its implementation, the author offers a definition of constitutional and legal guarantees of the right to vote.

In the red list of threatened species of Pará State, in Brazil, the salamander Bolitoglossa paraensis was listed as vulnerable. Initially the species was considered a synonym with Bolitoglossa altamazonica, but was recently revalidated. This note discusses the validity of the specimens from the west of the Brazilian Amazon identified as B. paraensis. It is also discussed the categorization of the species as vulnerable, and the records of the species was mapped in the Endemism area Belém. In order to establish a Private Natural Reserve (RPPN), a herpetological survey was carried out in different landscape units of the Nova Amafrutas, in Benevides (Pará), and the records of B. paraensis were mapped in these landscape units. By comparing the abundances recorded by Crump (1971) and those results of the present study, suggested that this species is tolerant to antropic “capoeira” forest (old fallows) next to undisturbed forest. More molecular phylogeographic studies are needed in order to establish a stable the taxonomy status for B. paraensis, and also the definition of its real endemic status in the Center of Endemism of Belém.

The article is devoted to issues of ensuring transparency and ac- countability of authorities in the conditions of participatory democracy (democ- racy of participation). It is argued that the public should be guaranteed not only the right for access to information but also the prerequisites for expanding its par- ticipation in state governance. These prerequisites include: the adoption of clearly measurable macroeconomic and social goals and the provision of control of the processes of their compliance with the government by citizens of the country; ex- tension of the circle of subjects of legislative initiative due to realization of such rights by citizens and their groups; legislative definition of the forms of citizens’ participation in making publicly significant decisions, design of relevant orders and procedures, in particular participation in local referendum; outlining methods and procedures for taking into account social thought when making socially im- portant decisions. The need to disclose information about resources that are used by authorities to realize the goals is proved as well as key performance indicators that can be monitored by every citizen; the efforts made by governments of coun- tries to achieve these goals. It was noted that transparency in the conditions of representative democracy in its worst forms in a society where ignorance of the thought of society and its individual members is ignored does not in fact fulfill its main task — to establish an effective dialogue between the authorities and so- ciety. There is a distortion of the essence of transparency: instead of being heard, society is being asked to be informed — and passively accept the facts presented as due. In fact, transparency and accountability in this case are not instruments for the achievement of democracy in public administration, but by the form of a tacit agreement between the subjects of power and people, where the latter passes the participation of an “informed observer”.

AbstractNot every speech act can be a lie. A good definition of lying should be able to draw the right distinctions between speech acts (like promises, assertions, and oaths) that can be lies and speech acts (like commands, suggestions, or assumptions) that under no circumstances are lies. This paper shows that no extant account of lying is able to draw the required distinctions. It argues that a definition of lying based on the notion of ‘assertoric commitment’ can succeed where other accounts have failed. Assertoric commitment is analysed in terms of two normative components: ‘accountability’ and ‘discursive responsibility’. The resulting definition of lying draws all the desired distinctions, providing an intensionally adequate analysis of the concept of lying.
