Доктрина методів тлумачення норм права, сформована в практиці Суду ЄС

The doctrinal approaches to the definition of methods and principles of interpretation of legal norms applied by the Court of Justice of the EU are analyzed. The traditional and special methods of interpretation inherent in integration justice are singled out. The dynamics of changes in the approaches to the interpretation of legal norms in the decisions of the Court of Justice of the EU after the signing of the Lisbon Treaty is described. Scientific approaches to defining the concept of interpretation of legal norms contained in domestic sources are analyzed. Foreign sources on the methods of interpretation of the law by the Court of Justice of the EU have been studied. The article analyzes several European publications written at different times before the signing of the Lisbon Treaty and established, which primarily draws attention to authors who have subjected the theological method of interpretation, and very few sources that influence the justification of methods or principles of their application by the Court. It can be concluded that the tendency of European scholars to emphasize the importance of the theological method of interpretation was related to their views on the constitutional nature of the Treaties and legal considerations about the need to adopt the EU Constitution. Such conclusions correlate with the limited jurisdiction of the Court of Justice, as before the signing of the Lisbon Treaty not all provisions of secondary legislation were interpretable (in particular, visas, asylum, immigration and other policies related to the movement of persons). on the constitutionality of the Treaties, although their form and content have become even more similar to constitutional acts, without losing a clear functional statement of provisions. Since then, the case law of the Court of Justice has been characterized by a variety of methods of interpretation, and European doctrine by publications that have re-substantiated the system of methods and paid more attention to their detailed analysis, making each of these methods autonomous and collectively interchangeable.Анализируются доктринальные подходы по вопросам определения методов и принципов толкования норм права, которые применяются Судом ЕС.

Managerial innovations in methodology of solving export-import activity problems and ensuring international corporations business excellence

The purpose of the research is to develop a new methodological basis for identifying, analyzing and solving problems of international corporations export-import activities and to ground the directions for ensuring their business excellence. The approach originality provides introduction of a conceptual model that aims to eliminate the negative symptoms of international corporations export-import activities based on the results of comprehensive market research, effectiveness of export-import activities and calculation of the integrated indicator of business excellence. The leading corporations of Slovakia and India in the production of bi-axially oriented polypropylene (BOPP) films were the primary basis for this study. The results of the research showed the need to implement a system of managerial innovation for reasoning the directions of ensuring international corporations business excellence. This is achieved because of using logically formalized methods and provides the improvement of organizational and structural interaction of management entities in the process of solving export-import activity problems. Important factors for ensuring business excellence are also the optimization of export and import costs, as well as an increase in export revenue for Slovak companies, and an increase in market share and cost optimization for Indian companies. The practical value of the obtained results is to develop a set of managerial innovations that can improve the efficiency of export-import activities and improve international corporations business

Fabrication and Characterization of Modulation-Doped ZnSe/(Zn,Cd)Se (110) Quantum Wells: A New System for Spin Coherence Studies

We describe the growth of modulation-doped ZnSe/(Zn,Cd)Se quantum wells on (110) GaAs substrates. Unlike the well-known protocol for the epitaxy of ZnSe-based quantum structures on (001) GaAs, we find that the fabrication of quantum well structures on (110) GaAs requires significantly different growth conditions and sample architecture. We use magnetotransport measurements to confirm the formation of a two-dimensional electron gas in these samples, and then measure transverse electron spin relaxation times using time-resolved Faraday rotation. In contrast to expectations based upon known spin relaxation mechanisms, we find surprisingly little difference between the spin lifetimes in these (110)-oriented samples in comparison with (100)-oriented control samples.Comment: To appear in Journal of Superconductivity (Proceedings of 3rd Conference on Physics and Applications of Spin-dependent Phenomena in Semiconductors

СТРАТЕГІЇ ПОДОЛАННЯ СТРЕСУ ТА ПЕРФЕКЦІОНІЗМ

Дезадаптивні стани, що порушують можливості адаптації до умов соціального середовища, виникають унаслідок комплексу взаємодії психологічних та соціальних факторів, які формують переживання стресу. Індивідуальні стилі подолання стресу, здатність до побудови інтегративної поведінки, зумовлюють ступінь стійкості до психічного стресу, ефективність навчання та міжособистісних взаємодій, стан здоров’я та якість життя студента, відповідно успішність у майбутній професійній діяльності. Набір копінг-стратегій студентів ВНМЗ характеризувався переважно як адаптивний: достовірно переважали особи з домінуючою адаптивною стратегією вирішення проблем, другою за частотоюбула умовно адаптивна стратегія пошуку соціальної підтримки, дезадаптивна стратегію уникнення застосовували як домінуючу найменша кількість студентів

Structural and biophysical analysis of nuclease protein antibiotics

© 2016 The Author(s); published by Portland Press Limited on behalf of the Biochemical Society. Protein antibiotics (bacteriocins) are a large and diverse family of multidomain toxins that kill specific Gram-negative bacteria during intraspecies competition for resources. Our understanding of the mechanism of import of such potent toxins has increased significantly in recent years, especially with the reporting of several structures of bacteriocin domains. Less well understood is the structural biochemistry of intact bacteriocins and how these compare across bacterial species. Here, we focus on endonuclease (DNase) bacteriocins that target the genomes of Escherichia coli and Pseudomonas aeruginosa, known as E-Type colicins and S-Type pyocins, respectively, bound to their specific immunity (Im) proteins. First, we report the 3.2 Å structure of the DNase colicin ColE9 in complex with its ultra-high affinity Im protein, Im9. In contrast with Im3, which when bound to the ribonuclease domain of the homologous colicin ColE3 makes contact with the translocation (T) domain of the toxin, we find that Im9 makes no such contact and only interactions with the ColE9 cytotoxic domain are observed. Second, we report small-Angle X-ray scattering data for two S-Type DNase pyocins, S2 and AP41, into which are fitted recently determined X-ray structures for isolated domains. We find that DNase pyocins and colicins are both highly elongated molecules, even though the order of their constituent domains differs. We discuss the implications of these architectural similarities and differences in the context of the translocation mechanism of protein antibiotics through the cell envelope of Gram-negative bacteria
