The origins of the teaching accounting in russian universities: lecturer and researcher Stepan Usov (1797 – 1859)
No full textThe authors of the paper explore the life and professional activity of Stepan Mikhailovich Usov (1797-1859), as well as his views on the theory and practical implementation of new accounting techniques in agriculture. Usov was a talented researcher, an expert in agricultural sciences, political economy, history, and the publisher and editor of a number of Russian magazines. He worked hard all his life to disseminate knowledge about progressive technologies of agronomy and farm bookkeeping. Usov became one of the first lecturers in accounting, which he taught at St. Petersburg University in 1836 and this is in the focus of the study. Based on the Actor–network theory of Bruno Latour (ANT), the authors contribute to the previous literature within biographical studies and accounting education by identifying Usov’s role in the development of Russian accounting as a mediator in the network of educational institutions, which transformed accounting into a university discipline

Interacciones tensivas : bolsabarismos de Mikhail Usov
No full textEn este ensayo definimos las prácticas como cursos de interacción encarnados corporalmente y acomodados estratégicamente. A partir de los presupuestos semióticos de esa defi nición abordamos una práctica cómica muy original e inédita ante la que solo queda acuñar una palabra también inédita («bolsabarismos»). No solo nos vemos obligados a forzar el lenguaje, debemos también afrontar un debate teórico en torno a un conjunto de categorías que dan forma al recorrido generativo del plano de la expresión y encontrar pistas metodológicas para emprender el análisis de ese caso concreto. Comprobamos que las interacciones tensivas atraviesan todo ese recorrido: funcionan en las escenas constitutivas de las prácticas integrando signos, textos y objetos, pero también acomodando estratégicamente las prácticas entre ellas e incluso desplegando formas de vida.</p
Increment of the collective pinning energy in Na1 − xCa x Fe2As2 single crystals with random point defects introduced by proton irradiation
No full textWe study the influence of random point defects introduced by 3 MeV proton irradiation (doses 1 × 1016 and 2 × 1016 cm2) on the vortex dynamics of Na x Ca1 − xFe2As2 (x = 0.5 and x = 0.75) single crystals. Our results indicate that the irradiation produces an enhancement of the critical current density and a reduction of the creep rate in vortex relaxation. The plateau in the temperature dependence of vortex creep rate initially present in as-grown single crystals disappears after irradiation. This fact can be associated with a large increment of the collective pinning energy (from <100 to 350–400 K). On the other hand, Maley analysis indicates that after irradiation both samples present a glassy exponent μ close to the one expected in the so-called large bundle regime (μ ≈ 7/9) for random point defects.Fil: Haberkorn, Nestor Fabian.

Structural characterisation and Kerr magnetometry of Fe/Mo(110) epitaxial system
No full textTHESIS 7579This thesis describes the investigation of the growth and magnetic properties of ultrathin
Fe films on the Mo(110) surface. The surface magneto optical Kerr effect (SMOKE)
setup was designed and built by author and used in conjunction with the surface
characterisation techniques to study magnetic anisotropy and magnetic phase transition in
Fe/Mo(110) films. The emphasis is made on correlation between magnetic properties and
film morphology
ETHICS OF LIABILITY K.-O.APELY IN THE LANDSCAPES OF CONTRACTUALISM
No full textThe purpose is to analyse comprehensively the work of the famous German philosopher K-O. Apel through the light of the urgent needs for a comprehensive study of modern contractualism and the development of new variants of philosophical anthropology. In this context to reveal April’s thesis that the main background for the possibility of understanding between people is the ideal communicative community and its attempts to discourse ethics, new, practical content. Methodology. In order to make a sequential analysis of the basic components and principles of ethical responsibility in K-O. Apel’s view of counteractualism the author uses genealogical, hermeneutic and comparative methods that allow to reconstruct Apel’s philosophy as the ethics of global responsibility and solidarity of communicative interaction under the conditions of global environmental and social crisis and the urgent need of vital combination of social contract idea, fairness and responsibility. Scientific novelty. The purpose of the article is clearly defined and productive methodological principles consistently enabled the author to find out that Apel perceives the source of social agreement in rational desire of each participant to obey voluntarily the relevant rules and procedures. And a true freedom and responsibility are based on the correlation of the rights and duties; respect them, which is more significant for the enforcement of their conventional or forced recognition. It is also investigated the attempt of K.-O. Apel to enable such an agreement and understanding between people, which would take into account the following important human virtues and aspirations, respect, justice and solidarity. And above all they are important as being the social and existential foundations for a new philosophical and anthropological discourse. It is consistently proved that in the context of substantial interest of justification was established the algorithms of universal values of modern philosophical anthropology, which will become the core of Apel’s responsible person. Excluding the ethical component of this or that agreement, the essence of democratic behaviour changes to rational behaviour of the participants and to the law validity of agreements belongs only the effectiveness in achieving the best interests of their members. It was reconstructed the memories of K.-O. Apel and Y. Habermas about the need and methodological importance of significance of epistemological (or methodological) solipsism of modern philosophy and its replacement by the concepts of "understanding", "agreement", "communication" within which even a single person can know and understand the world. Conclusions. An important feature of the latest philosophical theories, which include communication philosophy of K.-O. Apel is their organic belonging to the realm of discussion about the search of moral foundations of modern society where basic ethical guidelines and values must leave and eventually leave the sphere of private life, indicating that real attempts to overcome the fragmentation and dispersion of responsibility of the individual. It was exactly K.-O. Apel who stresses that collective irresponsibility should be replaced by collective responsibility
High-temperature change of the creep rate in YBa 2Cu 3O 7-δ films with different pinning landscapes
No full textMagnetic relaxation measurements in YBa 2Cu 3O 7-δ (YBCO) films at intermediate and high temperatures show that the collective vortex creep based on the elastic motion of the vortex lattice has a crossover to fast creep that significantly reduces the superconducting critical current density (J c). This crossover occurs at temperatures much lower than the irreversibility field line. We study the influence of different kinds of crystalline defects, such as nanorods, twin boundaries, and nanoparticles, on the high-temperature vortex phase diagram of YBCO films. We found that the magnetization relaxation data is a fundamental tool to understand the pinning at high temperatures. The results indicate that high J c values are directly associated with small creep rates. Based on the analysis of the depinning temperature in films with columnar defects, our results indicate that the size of the defects is the relevant parameter that determines thermal depinning at high temperatures. Also, the extension of the collective creep regime depends on the density of the pinning centers.Fil: Haberkorn, Nestor Fabian. Consejo Nacional de Investigaciones Científicas y Técnicas.
