We reinterpret the Faddeev–Popov gauge-fixing procedure of Yang–Mills theories as the definition of a topological quantum field theory for gauge group elements depending on a background connection. This has the advantage of relating topological gauge-fixing ambiguities to the global breaking of a supersymmetry. The global zero modes of the Faddeev–Popov ghosts are handled in the context of an equivariant cohomology without breaking translational invariance. The gauge-fixing involves constant fields which play the role of moduli and modify the behavior of Green functions at subasymptotic scales. At the one loop level physical implications from these power corrections are gauge invariant.

Meta Analyses

The determination of the post-mortal interval (PMI) is an extremely discussed topic in the literature and of deep forensic interest, for which various types of methods have been proposed. The aim of the manuscript is to provide a review of the studies on the post-mortem DNA degradation used for estimating PMI. This review has been performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the PRISMA Guidelines. Several analytical techniques have been proposed to analyse the post-mortem DNA degradation in order to use it to estimate the PMI. Studies focused mainly on animal models and on particular tissues. The results have been mixed: while on the one hand literature data in this field have confirmed that in the post-mortem several degradation processes involve nucleic acids, on the other hand some fundamental aspects are still little explored: the influence of ante and post-mortem factors on DNA degradation, the feasibility and applicability of a multiparametric mathematical model that takes into account DNA degradation and the definition of one or more target organs in order to standardize the results on human cases under standard conditions.

This article discusses the possibilities of using the innovative technology “inverted lesson” in combination with teaching in cooperation when teaching a second language at a university. The search for new technologies for training is due to the growing role of self-education in the concept of general cultural competencies of a modern specialist. Therefore, modern pedagogical technologies help students develop self-study skills. The advantages of the technology under study are found in an increase in the time for individual and independent work with students, in the ability to provide additional general cultural knowledge in parallel with the study of a certain thematic section on the one hand, as well as in the inclusion of students in active cognitive activity, the development of their independence on the other. The article shows the main approaches to the definition of the “inverted lesson” technology, gives its advantages and disadvantages, technical difficulties encountered in the implementation of the technology and, finally, the positive effect that can be achieved by using the “inverted lesson” technology in the classroom to study the second language among university students

Common Frame Of Reference

This article examines the emergence of organizational dynamics in the context of fluid organizational phenomena. To do so, three organizational dynamics are studied: (1) identity, (2) actorhood, and (3) interconnected instances of decision-making. To study how these three organizational dynamics take shape in the context of fluid organizational phenomena, I rely on the events-based approach and a case study of makers operating in a makerspace in the Paris region. The results show, on the one hand, that the collective of makers enacts a structure of past, present, and future events that participates in the definition of a common frame of reference and, on the other hand, that this common frame of reference plays a role in the emergence of organizational dynamics. On the basis of this result, my main contribution is to show the role of the eventalization – that is, the definition, configuration and narration by the actors of past, present, and future events – in the definition of organizational dynamics in fluid organizational phenomena. This article contributes on the one hand to the literature on fluid organizational phenomena, and on the other hand to the literature on makers working in makerspaces.

Abstract Hans Joas (born 1948) has repeatedly criticized Peter L. Berger (1929–2017) for placing religious experiences in the cognitive realm, where it runs the risk of being “contaminated” by secularization and pluralism. Instead, Joas has proposed to locate religious experiences in the “deeper layers” of the human person, where it is protected against mere cognitive reductionism and against contamination by secularization and pluralism. Despite his critique, Joas follows a similar path of Berger, as he explains the phenomenon of religion from an inductive point of view that originates in the experiential realm. This article demonstrates how Joas’ approach operates on a similar methodology like the one of Berger and ultimately results in similar theoretical conclusions despite their differing theoretical foundations. Moreover, this article illuminates an implicit methodological similarity between Joas and Berger that, on the one hand, differs from one of the taken-for-granted methodologies in the discipline of sociology (of religion), and, on the other hand, strongly influences the disposition of religious institutions in their definition of religion.

Communicative Activity

The article deals with the linguistic study of discourse which is based on the material of «Dia- ries» by O. Gonchar. In the focus of this research, diary entries are established as the projection and reflection of the linguistic personality of the writer. The process of keeping a diary is considered as the communicative value of text writing. Therefore, the entries reflect the results and characteristics of Gonchar’s communicative activity. The reflection of the word appears as a writer’s artistic work that absorbs the philosophy of his time, his aspiration and cultural experience. Moreover, the linguistic reading of the diary discourse reveals the axiсological perception of the reality, verbalized in the word. As noted by I. Sirko, in the Ukrainian linguistic culture only in the second half of the 20th century – at the beginning of the XXI century dia- ries became a form of personal expression. Due to the philological achievements, it is known that diary and diary activity form the discourse. If to quote the definition of discourse by N. Arutyunova, then discourse is a text immersed in life. Ac- cording to Y. Stepanov, the phenomenon of discourse is the proof of the thesis «Language is the home of the spirit» and, to some extent, the thesis «Language is the home of being». So keeping a diary is a kind of communicative activity. The concept of the diary accurately reflects the specifics of its keeping – a kind of activity that is implemented every day. Linguistic study of the diary’s discourse involves a variety of approaches, including 1) modeling of diary activity, 2) the selection of typical cases of diary writing and the main tendencies characterizing diary texts; 3) description and characterization of diary texts in the unity of language, psycholinguistic, cultural, extra-linguistic circumstances, which influenced the subject and led to creativity. In the diary discourse, we can trace the activities of the author in the role of «figure», the role of «chronicler», the role of «carrier of the psychological state», the role of «the one who writes». This is due to the wide possibilities of the diary. Naturally, in each case, these roles are individual. For example, O. Gonchar realizes himself in several different roles, which is reflected in the numerous entries. He includes all the information, such as drafts of letters, scenes of works, heard jokes or stories, interesting facts, personal or other observations, thoughts which the author consid- ered to be deserving for certain reasons to save. O. Gonchar is endowed with a degree of freedom in his communicative activity. He is free not only in the choice of lexical and syntactical means but also in the choice of topics (events) for a diary entry, as well as in measures of detail, describing a particular event. Thus, a diary is the prism of the vision of the writer’s world, the history of his experience and the formation of the author as a person. In addition, it is important to notice that the records often cover the entire life of the author, which allows us to trace the evolution of the linguistic personality, reconstruct the content of its worldview. In this way, diaries provide informational and communicative values, appear as a projection of the linguistic personality of the writer and reflection of the author’s language.

Semiotics, the age-old investigation of signs, is still striving for acknowledgement as a scientific (and academic) discipline. Though the ‘linguistic turn’ in the philosophical disciplines seemed to be followed by a ‘semiotic turn’ in many sciences during the 1970s, efforts were not crowned by great success. When seen from a certain distance, a definition of semiotics as a discipline can only be obtained from its history. Research into the sources of the human pre-occupation with signs, and with concepts or conceptions of signs, is really desirable and even necessary when a field of considerable scientific interest at the brink of being awarded the rank of a discipline runs the risk of getting lost between the unificationism of the Morris-type and the elegance of pseudo-mathematical empty classificationism (such as demonstrated in the late Max Bense's Stuttgart School) on the one side, and profitable exploitation of the sign's popularized design qualities on the other.

Gribov Copies

We analyze the Gribov problem for SU (N) and U (N) Yang–Mills fields on d-dimensional tori, d = 2, 3, …. We give an improved version of the axial gauge condition and find an infinite, discrete group [Formula: see text] where r = N − 1 and N for G = SU (N) and U (N) respectively, containing all gauge transformations compatible with that condition. This residual gauge group [Formula: see text] provides all Gribov copies for nondegenerate configurations in d = 2 and for those of them for which all winding numbers of the Wilson–Polyakov loop in one direction vanish in d ≥ 3. This shows that the space of gauge orbits is an orbifold. We derive this result both in the Lagrangian and in the Hamiltonian framework.

The infrared behavior of Yang–Mills theory at finite temperature provides access to the role of confinement. In this review recent results on this topic from lattice calculations and especially Dyson–Schwinger studies are discussed. These indicate persistence of a residual confinement even in the high-temperature phase. The confinement mechanism is very similar to the one in the vacuum for the chromomagnetic sector. In the chromoelectric sector screening occurs at the soft scale g2T, although not leading to a perturbative behavior.

Background Field Method

By making use of the background field method, we derive a novel reformulation of the Yang–Mills theory which was proposed recently by the author to derive quark confinement in QCD. This reformulation identifies the Yang–Mills theory with a deformation of a topological quantum field theory. The relevant background is given by the topologically nontrivial field configuration, especially, the topological soliton which can be identified with the magnetic monopole current in four dimensions. We argue that the gauge fixing term becomes dynamical and that the gluon mass generation takes place by a spontaneous breakdown of the hidden supersymmetry caused by the dimensional reduction. We also propose a numerical simulation to confirm the validity of the scheme we have proposed. Finally we point out that the gauge fixing part may have a geometric meaning from the viewpoint of global topology where the magnetic monopole solution represents the critical point of a Morse function in the space of field configurations.
