ASTROMETRIC RESEARCH IN UKRAINE AT THE XIX – BEGINNING OF XX CENTURIES

The paper presents the stages of development of astrometric research at the Ukrainian observatories in the ХIХ – beginning of ХХ century. They are related to the establishment of university astronomical observatories in Kyiv (1845), Odessa (1871), Kharkiv (1888). Mykolaiv Naval observatory was founded in 1821 for navigation needs with assistance of Admiral A.S. Greig. The absolute catalogs compiled at the Pulkovo and Mykolaiv Observatories made a significant contribution to the international work of compilation of a FK3 system. Special attention is paid to the scientific activity of the oldest observatory at the territory of Ukraine – the Astronomical observatory of L’viv University (1771). Researches at this observatory were mainly concerned with the field of geodesy and meteorology. Despite the short first period of scientific activity (near 10 years), it gave impetus to some famous scientists. At the last decades of ХIХ century observatory of the L’viv University renewed their activity in astrometry, solar physics, and astrophysics. Southern departments of Pulkovo observatory in Odessa (1899) and Mykolaiv (1912) played an important role in extension of Pulkovo absolute catalogues to the southern hemisphere. Systematic observations of the Sun conducted at these departments contributed to the more precise determination of the position of vernal equinox. In ХIХ century Ukrainian observatories participated in the international programs, such as AGK (Astronomischer Gesellschaft Katalog), the photographic catalog “Carte du Ciel” (France). Among the actual observational programs were surveys of zodiacal stars (M.P.Ditchenko in Kyiv), near-pole stars (V.I.Fabritius, R.P.Fogel, M.P.Ditchenko in Kyiv, L.O.Struve and K.N.Kuz'menko in Kharkiv, I.O.Djukov, L.F.Cherniev in Odessa). In the frame of observations of Bonner Durchmusterung (BD) and its southern continuation, organized by the German Astronomical Society, observations of the equatorial zone were provided by I.E. Kortazzi at Mykolaiv observatory, B.V.Novopashenny at the Astronomical Observatory of Odessa University in 1930s years. Needs of astrophotography lead to the creation of the “Сatalog of the faint stars” project. In 1932 at the First Astrometric Conference in Leningrad, the Pulkovo astronomers Gerasimovich B.P and Dniprovsky M.I. suggested the idea of using eхtragalactic nebulae as the reference objects for determination of the absolute motion of the stars. Among the tasks to be solved at the project was compilation of a general catalogue (KSZ) and a fundamental catalog of faint stars (FKSZ). It was planned to involve all the meridian instruments of the USSR as well as foreign ones, especially in the southern hemisphere. The idea of orientation of the KSZ coordinates system related to the observations of small planets was suggested by B.V.Numerov. Astronomers of Mykolaiv Astronomical Observatory participated in the international part of this project (AGK3R-catalogue). The Poltava gravimetric observatory was founded by A.Ya.Orlov in 1926 to construct a gravity map of the territory of Ukraine and to establish astrometric research, earth tides, and Latitude Service with zenith-telescopes. The main research fields of the Main Astronomical Observatory of the NAS of Ukraine, founded by A.Ya.Orlov in 1944, were related to the positional and photographic astrometry during the first decade of its work. We defined three “genealogical scientific trees” of astrometric schools. Two of them were formed under the leadership of outstanding personalities of the XX century: Prof. Alexander Ya. Orlov (the founder and first director of the Observatory, 1944–1948, 1950–1951), who moved to Kyiv from Poltava, and Prof. Avenir A.Yakovkin (director of the Observatory in 1952–1959), who moved to Kyiv from Kazan. The third genealogical tree has grown from the Pulkovo astronomical school. Formation of main directions of scientific researches and its transformation are also discussed. Keywords: astrometric research, positional astrometry, photographic astrometry, fundamental astrometry.

Fragmentations with self-similar branching speeds

We consider fragmentation processes with values in the space of marked partitions of $\mathbb{N}$, i.e. partitions where each block is decorated with a nonnegative real number. Assuming that the marks on distinct blocks evolve as independent positive self-similar Markov processes and determine the speed at which their blocks fragment, we get a natural generalization of the self-similar fragmentations of Bertoin (Ann. Inst. H. Poincaré Prob. Statist.38, 2002). Our main result is the characterization of these generalized fragmentation processes: a Lévy–Khinchin representation is obtained, using techniques from positive self-similar Markov processes and from classical fragmentation processes. We then give sufficient conditions for their absorption in finite time to a frozen state, and for the genealogical tree of the process to have finite total length.

Familial hyperinsulinaemic hypoglycaemia with epileptic syndrome, cognitive impairment and detected mutation of the ABCC 8 (SUR1) gene: a case report

Hyperinsulinaemic hypoglycaemia (HH) occurs as a consequence of unregulated insulin secretion from pancreatic beta cells. It is the most common cause of severe and prolonged hypoglycemia in newborns. HH is a major risk factor for brain damage and subsequent neurological disability, which is why the identification, rapid diagnosis, and timely treatment of patients with HH are essential for the prevention of brain damage. The present case gives a brief description of a patient with congenital HH with an established mutation in the ABCC8 gene encoding the SUR1 subunit of the K-ATP channel. The genealogical tree, the clinical picture, the diagnostic cascade, the neurological consequences and their development in dynamics are considered, with special emphasis on the epileptic syndrome and mental status. Advances in molecular genetics, radiological imaging techniques, conservative treatment, or laparoscopic surgery may completely change the clinical approach to children with severe congenital forms of HH.

Diez, Meyer-Lübke, and Co. The Founding of Romance Linguistics

The study of Romance linguistics was born in the 19th-century German university, and like all linguistics of that era it is historical in nature. With respect to Indo-European and Germanic linguistics, a difference was immediately apparent: Unlike Indo-European and Common Germanic, Latin’s attestation is extensive in duration, as well as rich and varied: Romance linguists can thus make use of reconstruction as well as documentation. Friedrich Diez, author of the first historical grammar and first etymological dictionary on Romance languages, founded Romance linguistics. His studies singlehandedly constructed the foundations of the discipline. His teaching soon spread not only across German-speaking countries, but also into France and Italy. Subsequently, the most significant contributions came from two scholars trained in the Indo-European field: the German linguist Hugo Schuchardt, whose doctoral thesis studied with sharp theoretical awareness the passage from Latin to the Romance languages, and the Italian Graziadio Isaia Ascoli, who showed how the Romance panorama could be extraordinarily enriched by the analysis of nonstandard varieties. The discipline thus developed fully and radiated out. Great issues came to be debated: models of linguistic change (genealogical tree, wave), the possibility of distinguishing dialect groups, the relative weight of phonology, and semantics in lexical reconstruction. New disciplines such as linguistic geography were born, and new instruments like the linguistic atlas were forged. Romance linguistics thus became the avant-garde of general linguistics. Meanwhile, a new synthesis of the discipline had been created by a Swiss scholar, Wilhelm Meyer-Lübke, who published a historical grammar and an etymological dictionary of the Romance languages.

“They Don't Represent Us!”: From the Crisis of the Organic Intellectuals of 1978 to the Exhumation of Buried Imaginaries

Based on the notion of événement (event), elaborated by the French philosopher Alain Badiou, this essay aims to offer a definition of the 15M movement as an event. According to Badiou, the event has the capacity to perforate established knowledge and to transform the codes of communication. The event destabilizes the regime of truth to the extent that what was assumed to be obvious now appears as unstable, and, consequently, the need arises to explore and construct other discourses capable of naming the new situation. In this essay, I locate two moments of the event: the political moment and the theoretical moment; the first is the time of the revolution, while the second is devoted to the study and theorization of this revolution. I argue that the radical effects of the event can be registered in the second moment. In the theoretical moment, there is a crisis of the organic intellectuals of the Regime of ’78, and the empty space they leave behind may begin to be occupied by other voices that were previously barely heard. In the same way, during the theoretical moment, the revolution without a genealogical tree that was the 15M, which was not inscribed in a revolutionary continuity, begins to seek its roots in discourses of the past that were silenced or forgotten, or that simply did not have a framework that would give them back their conditions of legibility.

Academic Performing Traditions of Chilean Guitar Art

The relevance of the article lies in the systematization of the phenomena of the Chilean academic guitar art, the study of the national origins of the performing school, its principles, achievements, transcultural processes and their mutual influences, which led to the popularization of the instrument on the Latin American continent. The purpose of the article is to create an overview panorama of the development of the academic traditions of Chilean guitar performance, to identify trends in the formation and genealogy of successive ties between generations of soloists. The methodology includes methods of historical, systemic, as well as comparative analysis (for contextual consideration of the creative activities of famous performers, the formation of a national guitar school, the detection of successive ties between different generations of musicians, the study of the influence of the Spanish academic tradition, Latin American everyday practice of playing and the specifics of playing music on ancient guitar-like instruments of the Baroque era). Results and conclusions. The cultural and historical panorama of the formation and development of the Chilean academic guitar school of the 20th— early 21st centuries is investigated. The principles and main vectors of the pedagogical activity of its key representatives — Liliana Perez Corey, Luis Lopez, Oscar Ohlsen are characterized. A “genealogical tree” of creative contacts and successive ties between guitarists of different generations has been built. It is concluded that the academic traditions of the Chilean guitar music of the 20th century were formed in the general direction of the development of transcultural phenomena. The performing discourse developed in a complementary way: under the influence of the most famous Spanish classical guitar school that dominates the world (F. Tarrega, A. Segovia, E. Pujol); in the conditions of indirect interaction with the Latin American everyday practice of playing (Argentinean, Uruguayan, Chilean) and the experience of playing music on ancient authentic European instruments (lute, vihuela, baroque guitar). It is noted that as a result of the intensification of creative exchange in the institutional, concert, and festival spheres, at the end of the twentieth century, a representative generation of virtuosos and teachers of classical guitar arose in Chilean culture. Chilean guitarists, no matter in which of the spheres their personal interests were fixed — European old, classical-romantic, modern music or Latin American popular, folklore tradition — put forward the creativity of their compatriots and contemporaries to the leading positions. The appearance of a large number of albums of Chilean guitar music performed by J. A. Escobar, J. Contreras, M. Valdebenito, J. A. Sanchez, L. Orlandini, E. Espinoza, E. Salazar, D. Castro is evidence of close and effective cooperation between virtuosos and domestic composers.

Exact simulation of the genealogical tree for a stationary branching population and application to the asymptotics of its total length

We consider a model of a stationary population with random size given by a continuous-state branching process with immigration with a quadratic branching mechanism. We give an exact elementary simulation procedure for the genealogical tree of n individuals randomly chosen among the extant population at a given time. Then we prove the convergence of the renormalized total length of this genealogical tree as n goes to infinity; see also Pfaffelhuber, Wakolbinger and Weisshaupt (2011) in the context of a constant-size population. The limit appears already in Bi and Delmas (2016) but with a different approximation of the full genealogical tree. The proof is based on the ancestral process of the extant population at a fixed time, which was defined by Aldous and Popovic (2005) in the critical case.

PRACTICAL USE OF ARCHIVAL DOCUMENTS WITHIN GENEALOGICAL RESEARCH IN UKRAINE

The purpose of the article is to analyze the features of the practical use of archival documents in the process of genealogical research in Ukraine. The methodology used general scientific methods such as analysis and generalization. A descriptive method was also used, which allowed revealing this issue in more detail. The scientific novelty of the presented work consists in expanding ideas about the practical use of archival documents in the process of genealogical research in relation to the study of the genealogy of a kind and the creation of a genealogical tree. Conclusions. Genealogy today is a separate interdisciplinary field, which is a special way reflects the historicism of the social consciousness of famous people of today, their place in the social structure of society. In modern conditions of increasing interest in the genealogy of the genus, the analysis of the peculiarities of the search for genealogical information is not only theoretical but also practical. Therefore, the essential goal of the functioning of archives – the use of retrospective documentary information – is fully realized. Along with documentary sources (certificates, acts, metric books, wills, church descriptions, etc.) narrative (descriptive) archival sources are important in the process of genealogical research. Genealogical resource, which is accumulated in the archives of Ukraine, is divided into two large groups: 1) pedigrees in any form (family tree, family table, family list, etc.); 2) other types of sources that contain important information about a person, his life and environment (documents of state and public institutions that have a mass character and determine family ties between people, church metric books, census documents, etc.). Archival documents, both official and private, play the most important role in the accumulation of reliable genealogical information about a particular genus or family chronicles. Key words: genealogical research, archive, archival documents, genealogical information, archival institutions, parish registers (metrics books), census records.

Pervasive Fetishism

We all have the propensity to materialize our elusive sense of belonging to others. We are pervasive social fetishists, creating placeholders of our social alliances by making them more tangible for self and for others. In all social groups, there is indeed a pervasive propensity to objectify alliances, transforming them into something more fathomable and collectively shared, something that has visibility like a flag, a totem, a genealogical tree, a uniform, or etiquette or mannerisms like gang idiosyncratic tags or gestures. It is the transformative process of alliances into something physical that everybody can refer to in an animist and fetishist way. “Thinging” and associated fetishisms are major reinforcing mechanisms of social clustering, stereotyping, and other social categorizing processes. At a social and, ultimately, ethical level, it also pertains to how we tend to construe others as groups. It captures the way we perceive elusive essence as tangible characteristics, justifying the clustering of individuals into groups, a process that reinforces and is the source of stereotypes and shortcut moral reasoning.
