Causal Approach

The causal perturbation theory is an axiomatic perturbative theory of the S-matrix. This formalism has as its essence the following axioms: causality, Lorentz invariance and asymptotic conditions. Any other property must be showed via the inductive method order-by-order and, of course, it depends on the particular physical model. In this work we shall study the normalizability of the generalized quantum electrodynamics in the framework of the causal approach. Furthermore, we analyze the implication of the gauge invariance onto the model and obtain the respective Ward–Takahashi–Fradkin identities.

Warfare may be understood as violent social encounter with the Other, and has in this sense occurred from the first hominid societies until today. Ample evidence of war-related violence exists across time and space: skeletal traumata, material culture, weapons, war-related ritual finds, fighting technologies, fortifications, and martial iconographies. The archaeology of war is a late ‘discovery’ of the mid 1990s, but advances have recently been made in understanding the scale and roles of warfare in pre- and protohistory and how warfare and warriorhood relate to society, culture, evolution and human biology. This chapter ventures into this discursive field from a theoretical and archaeological point of view while reflecting upon the effectiveness and role of war as a prime mover in history. It is argued that war was often present but never truly endemic, and that war essentially is a matter of culture.

The way mathematics instruction accommodates the large technological changes sweeping society will profoundly affect the ability of young people to adjust to everyday life situations and perform efficiently in the skilled professions of the future. In particular, continued thoughtful attention must be given to the role of microcomputers in all aspects of the teaching of mathematics. Many significant issues in this area will need to be discussed and important decisions made in the months ahead. We need to set high expectations in these discussions and the decisions that follow from them. Settling for what can be done easily or selling short the talents of our students or our colleagues will be a mistake.

The discovery of x-rays, one of the most beautiful experiments ever carried out, generates numerous controversies and these, in turn, can trigger a series of counterproductive information regarding not only the History of Science but also the teaching  activity. The aim of this article is to resolve these controversies concerning what ocurred and highlight the important role of the German physicist Wilhelm Conrad Röntgen, highlighting not only his genius but, especially in this case in particular, his condition of second-order observer. It is not uncommon to find information in various media refering to this discovery under the claim that it was the result of a fortuitous event, and this denotes a profound lack of knowledge about the facts or a disrespect for the renowned discoverer. Such allegations about the event depreciate the extraordinary discovery that impacts humanity, from the deed  to the present. Thus, through a brief historical reconstruction, it was tried to present here what had happened judiciously. With this respect, the brilliant scientist is given the status of a second-rate observer, from the philosophical point of view. This condition resonates with the diachronic aspect of the History of Science, according to the perspective presented here, and it is also supported by the time taken by the discoverer from the beginning of his research until the end of it. Keywords: X-Ray.

O presente artigo tem como objetivo dirimir tais polêmicas com respeito ao ocorrido e destacar o importante papel do físico alemão Wilhelm Conrad Röntgen, destacando não só sua genialidade, mas sobretudo, neste caso em particular, a sua condição de observador de segunda ordem. Não é raro encontrar em diversos meios de comunicação informações com respeito a referida descoberta sob a alegação de que a mesma fora fruto de um caso fortuito e isso denota profundo desconhecimento sobre os fatos, ou então, desrespeito com o renomado descobridor. Tais alegações sobre o sucedido depreciam a descoberta extraordinária que impacta a humanidade, desde o feito até a atualidade. Assim, através de breve reconstrução histórica, buscou-se aqui apresentar o ocorrido criteriosamente. Com este respeito passa-se a atribuir ao brilhante cientista a condição de observador de segunda ordem, do ponto de vista filosófico. Tal condição encontra ressonância no aspecto diacrônico da História da Ciência, segundo a perspectiva aqui apresentada e está amparada, também, pelo tempo empreendido pelo descobridor desde o início de sua pesquisa até a finalização da mesma. Palavras-chave: Raios-x.

Эволюция - это естественный исторический процесс развития, совершенствования, в том числе и основных государственных законов. Порядок пересмотра и внесения поправок - это процесс, который предусмотрен и происходит при конституционном становлении любого государства. Статья посвящена изучению характера некоторых поправок, внесенных в Конституцию Российской Федерации с недавнего времени. Кроме того, в статье проанализирована роль Конституции Российской Федерации как основного законодательного акта в стране, раскрыты основные принципы, изложенные в Конституции РФ и имеющие значение для внесенных поправок. Авторы отмечают, что внесение поправок в Конституцию РФ затронуло только содержание с третьей по восьмую главы, поскольку внесение изменений в первую, вторую и девятую главы Конституции РФ невозможно и влечет принятие новой Конституции страной. Тем не менее актуальность даже некоторых корректоров в основополагающем законодательном акте Российской Федерации обусловлена взаимосвязью всех положений Конституции, и после изменения хотя бы одной нормы Конституции неизбежно следуют некоторые поправки в иных нормах этого же акта. Далее авторы анализируют внесенные поправки относительно отображения в Конституции титульной нации. До недавнего времени данное положение отсутствовало, в отличие от положений конституций некоторых зарубежных государств, приводимых авторами в исследовании. Кроме того, отмечаются некоторые изменения преамбулы, которые нашли свое отражения в ст. 67 Конституции РФ, а также особенности установления идеологии на территории Российской Федерации. Относительно последнего авторы справедливо указывают, что, несмотря на запрет установления идеологии в стране, согласно внесенным поправкам в Конституцию РФ Российская Федерация должна придерживаться концепции патриотизма. В статье приводится точка зрения о нарушении порядка принятия поправок в Конституцию РФ, а также негативные последствия данного нарушения. В заключение авторы указывают, что, несмотря на особенности внесения поправок в Конституцию РФ, они тем не менее были реализованы, хотя и не решили существующих проблем в Российской Федерации. Evolution is a natural historical process of development, improvement, including the basic state laws. The procedure for revision and amendment is a process that is provided for and occurs during the constitutional formation of any state. The article is devoted to the study of the nature of some amendments made to the Constitution of the Russian Federation recently. In addition, the article analyzes the role of the Constitution of the Russian Federation as the main legislative act in the country, analyzes and reveals the basic principles set out in the Constitution of the Russian Federation and are relevant for the amendments made. In the study, the author correctly notes that the amendments to the Constitution of the Russian Federation affected only the content of the third to eighth chapters, since the introduction of amendments to the first, second and ninth chapters of the Constitution of the Russian Federation is impossible and entails the adoption of a new Constitution by the country. Nevertheless, the relevance of even some correctors in the main legislative act of the Russian Federation is conditioned by the interrelation of all the provisions of the constitution with each other and the change of at least one norm of the Constitution is inevitable by some amendments to other norms of the same act. Further, the author analyzes the amendments made regarding the inclusion of the titular nation in the Constitution, since this provision was absent until recently. This, in turn, cannot be said about some foreign countries, the provisions of whose Constitutions the author cites in the study. In addition, the author notes some changes in the preamble, which are reflected in Article 67 of the Constitution of the Russian Federation, as well as features of the establishment of ideology on the territory of the Russian Federation. Regarding the latter, the author rightly points out that despite the ban on the establishment of ideology in the country, according to the amendments to the Constitution of the Russian Federation, the Russian Federation should adhere to the concept of patriotism. The article presents the point of view about the violation of the procedure for adopting amendments to the Constitution of the Russian Federation, as well as the negative consequences of this violation. In conclusion, the author points out that despite the peculiarities of the amendments to the Constitution of the Russian Federation, they were nevertheless implemented, although they did not solve the existing problems in the Russian Federation.

The electron self-energy (self-mass) is calculated on the basis of the model of quantum field theory with maximal mass M, developed by V. G. Kadyshevsky et al. within the pseudo-Hermitian quantum electrodynamics in the second order of the perturbation theory. In theory, there is the natural cut-off of large transmitted momentum in intermediate states because of presence of the universal mass M. As a result, the electron self-mass is finite and depends on the transmitted maximum momentum [Formula: see text]. Two interpretations of the obtained results are possible at defined M and A. The first interpretation allows confirming quantitatively the old concept of elementary particle mass sources defined by interaction of particles with self-gauge fields. The second interpretation results in the possibility not to renormalize the mass (at least in the second order of perturbation theory) owing to the zero mass operator ∑(p).

My paper examines Derrida's attempts to resist, on the one hand, what he thought of as the increasing international hegemony of American English as the technolanguage of communication, and, on the other hand, forms of linguistic nationalism, when using the resources of the French language to deploy the syntagma: démocratie à venir. It does this by investigating what happens when claims about democracy are made in such a way as to be singularly idiomatic – made from a cosmopolitan point of view that takes into account, rather than vitiates à la Kant, the singular poeticity of idioms. It contrasts Derrida's analysis of the relationship between the national, democracy and idiomaticity with Tocqueville's nationalistic claims; examining, in particular, the issue of how language supposedly binds people together, the role of singularity and generality in thinking about idioms, the divide between originary and techno-scientific idioms, and Derrida's practice of writing in plus d'une langue. It also outlines how, paradoxically, it is a form of idiomaticity and not linguistic instrumentality that disrupts the logic of appropriation, the logic inscribed in the neighbouring, though different, conceptual values of idion, proprius and le propre.

Recent advances made in the understading of the Ramond-Neveu-Schwarz formulation of superstring perturbation theory are reviewed. The role of chiral splitting, in terms of which a consistent GSO projected formula is obtained to all loop orders, is explained. Equivalence of the manifestly convariant Polyakov amplitudes with the manifestly unitary light-cone amplitudes is shown, thus establishing unitarity of the covariant approach and Lorentz invariance of the light-cone approach. Some implications for string theory and quantum gravity are pointed out.

The issue of choosing the commune executive body is important both from a democratic, and a social point of view. In the theoretical-practical article, an attempt was made to: − cataloging the most important legal acts and other regulations focused on local government elections (from the perspective of choosing the commune executive body); − indication of changes in the electoral law made in 2018 that are the background to the practical part of the article − defining the role of local government as the organizer of local government elections among other entities involved in the preparation and conduct of the elections. In addition, using the example of the city of Dąbrowa Górnicza, organizations of local government elections were presented from the point of view of the selection of the commune executive body (in particular, its organizational aspect against the results)
