THE REGION IMBALANCES AND THEIR ROLE IN PROMOTING THE REGIONAL MARKETING DEVELOPMENT
Authors: KUZMYNCHUK Nataliia , KUTSENKO Tetiana
Published: July 2021

The purpose of the article is to investigate the features of regional development disparities in terms of increasing asymmetric processes in the context of the implementation of regional marketing tasks aimed at increasing the attractiveness of territories. It is substantiated that in order to regulate asymmetric processes in the regions, one should consider the region as a quasi-state and, accordingly, to create mechanisms for regulating regional development on the complex combination basis of strategic planning, financial and investment regulation, marketing advancement proposed in the strategy of regional development of ideas and approaches to their implementation. It is emphasized that the mechanism of regional development regulation, formed on this basis, ensures the achievement of the regional policy goals in the context of regional marketing. It is established that the disproportionality of the regions’ development is based on the unevenness of natural resources, human and production potential, as well as the lack of spatial development and placement of productive forces. Increasing disproportionality creates risks and threats not only to the economic unity of the state, but also causes a deterioration of the situation in the socio-economic sphere in the regions of the country.

A set of measures is proposed to prevent the unevenness development into a real threat of disruption of the consolidated economic space, which will allow to focus attention on perspective directions of the region development on the basis of using marketing methods and tools for promotion of territories. Since marketing (marketing tools) is an important component of regional governance, along with socio-economic and financial management, it can be used as an element of effective planning for the economic development of a region in order to improve it, in particular in the context of regular support for entrepreneurial activity in order to achieve a positive image. Prospects for further research are to develop a mechanism for eliminating the disproportionality of regional development based on the principles of regional marketing.
FORECASTING THE EXPORT POTENTIAL OF UKRAINIAN GRAIN INDUSTRY ENTERPRISES, TAKING INTO ACCOUNT THE LEVEL OF DEVELOPMENT OF DOMESTIC SELECTION
Authors: CHERNIAVSKYI Ivan
Published: July 2021

The scientific article is devoted to the problem of forecasting the grain production volume and enterprise export potential of the Ukrainian grain industry (taking into account the development level of domestic breeding) for the medium term under 3 alternative scenarios. Grain sowing area was forecasted by 2023 using an adaptive forecasting model. The results of the conducted research show that by 2023 the area of corn sowing will increase to 4922 thousand hectares. The corn yield forecast for 2023 has been developed, which shows that the yield level will increase substantially. So, if in 2017 the yield of this crop was 61 hwt / ha, then on average in 2023 it will be 76.6 hwt / ha. It is established that yield is one of the main factors for increasing the volume of grain production. The forecast suggests that on average, corn grain exports from Ukraine tend to grow in the future, namely that it will grow by 11.8 % in 2023 compared to the 2018/2019 marketing year and amount to 30835 thousand tons. Under the optimistic scenario, corn production in the year 2023 will be 42536 thousand tons, which is 54.4 % more than in the 2018/2019 marketing year. The results of the study show that in the future (by 2023), the volumes of maize seeds use will increase – on average they will increase by 8 %, and by the optimistic forecast – by 25 % compared to the 2018/2019 marketing year and will amount to 585 thousand tons.

The analysis shows that in 2019 there was a rapid development of both world and Ukrainian breeding. Thus, analyzing the varieties of the main grain crops, it should be noted that in the analyzed period the number of registered varieties suitable for distribution in Ukraine increased by 11.7 times, including the domestic ones – 10.5 times. Accordingly, maize grew 21.8 times and 14.4 times, respectively. It is worth noting a fairly high proportion of domestic wheat varieties, whose share is 72 %. What cannot be said for other crops, in particular, the share of domestic varieties is only 47 %.

In the medium to long term, Ukraine can increase its seed exports by a dozen times. Opportunities for capacity-building of seed plants are steadily increasing every year. Large seed companies, such as “Pioneer”, “Monsanto”, “Syngenta”, “Moisadur”, “Euralis Semens” and domestic “Mais”, “Eridon”, “Selena”, “Eurostandard”, have potential to attract foreign investments to bring Ukraine to the forefront in sales of cereal seeds (wheat, barley, oats, rye and corn) and oilseeds (sunflower, soybean, mustard and rapeseed).

Authors: SELIKHOV Sergii
Published: July 2021

The cost of modern innovative methods in winemaking requires finding ways to optimize the use of enterprise resources and reduce production costs. Another effective way is to introduce process innovation.

The purpose of the article is to substantiate the feasibility of implementing managerial innovations in wineries and to determine the algorithm for assessing the readiness of the environment for their implementation.

The directions of introduction of managerial innovations are considered. The types of managerial innovations in the field of personnel management are presented: recruiting, personnel audit and personnel coaching. The experience of foreign countries in the managerial innovations implementation is considered. Aspects of the analysis of the need for managerial innovations implementation are identified: as a tool and as a consequence. The introduction features of product and technical and technological innovations are determined. The definition of the concept of «organizational lag» has been given, which reflects the implementation of industrial innovations in the old management structures and methods, which reduces both their efficiency and the enterprise as a whole. The role of communication process in the enterprise management system is considered. The algorithm of communication aspects estimation of managerial innovations implementation at the enterprises by organizational, information, technological, social and psychological subsystems is presented. The role of the organizational management structure and the information subsystem in providing effective communications is presented. The role of the human factor in the communication process is defined. Using the developed algorithm will allow to identify bottlenecks in the communication process and to determine ways of overcoming them.

Depending on the problems identified, their depth, importance and urgency, various measures may be taken to improve the enterprise communication system and approaches to regulating staff work: economic stimulation, adjustment of the social and psychological climate in the team, conflict resolution, professional development and training in terms of preparing staff for innovative changes etc.

UNCONDITIONAL BASIC INCOME AS A TOOL FOR IMPROVEMENT OF THE SOCIAL SECURITY SYSTEM
Authors: PUSНAK Yaroslav , MARCHENKO Olha
Published: July 2021

Introduction. In connection of the exacerbation of the global problem of poverty and property inequality, the crisis of existing social welfare systems, the attention of scholars and practitioners is focused on finding new tools for social protection of the population. As a consequence, scientific research and practical experiments on the introduction of unconditional basic income in the world are being updated.

The purpose of the article is to substantiate and determine the prerequisites for improvement of the social security system of the population based on the concept of basic income in Ukraine.

Results. The relevance of the study of the preconditions, advantages, potential results and problems of introduction of unconditional basic income in Ukraine are substantiated. The authors consider the theoretical grounds for the expediency of its application in our country to compensate citizens for lost access to natural resources in an oligarchic-clan economy.

An ability and sources of financing of unconditional basic income in Ukraine are analyzed. It is proposed to improve the taxation system (introduce a progressive income tax rate scale) and fiscal instruments (in particular in the area of natural resource rentals) for this purpose. The prerequisites for the introduction of basic income are defined: a high level of civic awareness and economic consciousness of the population, a stable and effective tax system, the deduction of income and property.

Based on the analysis of the social structure of the population of Ukraine, its citizens’ self-assessment of their incomes, the assumption is made about the inefficiency of basic income as a stimulator of human capital development in the direction of entrepreneurship and creativity in the short term after its introduction. It is suggested that basic income in Ukrainian realities can have a positive effect on solving problems such as labor emigration, demographic situation, decline of the Ukrainian village, which requires appropriate social experiments.

Conclusions. As a result, it is concluded that the use of unconditional basic income in Ukraine in combination with other social transfers is feasible under the conditions of: reforming the system of taxation and payments for the use of natural resources; legalization of shadow income; raising social standards to an objective level of satisfaction of human physiological and spiritual needs; strengthening the control over the efficiency of use of budgetary funds; stimulating investment in human capital; infrastructure improvements; raising the standard of living of the poorest population groups.

Authors: Nasibova Olha
Published: July 2021

Introduction. The economic recession and the growing number of poor people, including the able-bodied, have opened up a complex of contradictions and exacerbated the internal dysfunctions of the social protection system, a mandatory element of which is state social standards and guaran-tees. Social guarantees determine the degree of state responsibility to its citizens and provide a certain standard of living for all segments of the population. An effective and efficient system of social guarantees, as well as its proper financial support will increase the welfare of citizens.

The purpose of scientific research is to determine the mechanism of formation and implementation of state social standards and guarantees, analysis of their financial support.

Methodology. In the course of research system, structural methods, and also methods of comparison, the analysis and synthesis, induction and deduction have been used.

Results. The article considers the economic essence and legal regulation of state social guarantees. The problematic issues of formation and implementation of state social guarantees are singled out and analyzed. The dynamics of state social guarantees for 2000-2019 is given. Peculiarities of determining the size of the subsistence minimum as an important parameter of the state policy of social and economic development are investigated. The role of the minimum wage and its relationship with the subsistence level has been identified. The sources of financial support of social guarantees are characterized. The main directions of improving the mechanism of state guarantees realization of social development are determined.

Conclusions. In the process of harmonizing the population’s consumption of the set of vital goods between the state and society, the system foundations of state social standards and guarantees are laid, which are formed depending on the level of economic development, historical traditions, types of socio-economic system, gross domestic product redistribution model. Insufficient effectiveness of the implementation mechanism of state standards and guarantees of social development is caused by limited financial security, as well as existing problems of substantive characteristics of basic concepts, the solution of which will streamline the terms used and improve the quality of state social standards and guarantees. To ensure the effective use of the subsistence level, it is necessary to constantly revise the structure of standards for calculating its components, update sets of goods and services taking into account the current living conditions of all categories of the population, adjust the ratio of food, non-food goods and services according to real cost indicators, taking into account the needs of normal human reproduction, the dynamics of change in the average family size for the relevant period.

MANAGING PUBLIC PROCUREMENT APPEALS
Authors: SLOBODIANYK Anna , REZNIK Nadiya
Published: July 2021

Introduction. The main purpose of the public procurement system is determined by the need to ensure efficient use of budget funds in the development of competition, transparency and openness of the procurement process organization.

The purpose of the research is to conduct the process analysis of contesting the public procurement procedure by tenderers.

Results. The authors argue that evaluating the dispute resolution effectiveness between the complainant and the customer on the basis of the balance of rights, interests, and objectives of the procurement law is, in practice, an extremely difficult issue that must be resolved in each individual case. The specifics of determining the procurement subject by the customer are highlighted in such a way as to preserve the right to choose the product that suits him best and not to buy the cheapest existing product on the market, such as paper according to certain parameters of density and level of linen. But if the customer has already defined in the tender documentation technical and the qualitative characteristics of the procurement subject, he has no right to further deviate from them when selecting the winner. It is proved that the appeal procedure is created specifically to ensure a quick and professional settlement of conflicts between the participant or potential participant of the procurement procedure and the customer regarding the actions of the customer, which violate the right of such participant in the procurement procedure and the conclusion of the contract with the customer. Attention is drawn to the appeal terms of the tender documentation claim being challenged and the possible addition of justification for the need to amend the conditions of the tender documentation with the opportunity to give additional evidence.

Conclusions. From the moment of the procurement contract conclusion between the state customer and the successful tenderer, classic private legal relations emerge, and consequently, after the conclusion of the procurement contract for public funds, which is the final stage of the procurement procedures, civil rights and obligations arise between the parties, and consequently civil rights and obligations arise to appeal the procurement procedure.

A total of 88% had radiological alterations upon admission (two patients had an X-ray within normality) and 29% had elevated procalcitonin. Mortality in our series was 12%. Conclusions. It could be reasonable to consider the start of antimicrobial therapy in those cases in which there is a moderate or high suspicion of bacterial coinfection, being essential the early suspension of antibiotic treatment if it is not confirmed
A Note on Restricted Online Ramsey Numbers of Matchings
Authors: Dvořák Vojtěch
Published: July 2021

Consider the following game between Builder and Painter. We take some families of graphs $\mathcal{G}_{1},\ldots,\mathcal{G}_t$ and an integer $n$ such that $n \geq R(\mathcal{G}_1,\ldots,\mathcal{G}_t)$. In each turn, Builder picks an edge of initially uncoloured $K_n$ and Painter colours that edge with some colour $i \in \left\{ 1,\ldots,t \right\}$ of her choice. The game ends when a graph $G_i$ in colour $i $ for some $G_i \in \mathcal{G}_i$ and some $i$ is created. The restricted online Ramsey number $\tilde{R}(\mathcal{G}_{1},\ldots,\mathcal{G}_t;n)$ is the minimum number of turns that Builder needs to guarantee the game to end.

In a recent paper, Briggs and Cox studied the restricted online Ramsey numbers of matchings and determined a general upper bound for them. They proved that for $n=3r-1=R_2(r K_2)$ we have $\tilde{R}_{2}(r K_2;n) \leq n-1$ and asked whether this was tight. In this short note, we provide a general lower bound for these Ramsey numbers. As a corollary, we answer this question of Briggs and Cox, and confirm that for $n=3r-1$ we have $\tilde{R}_{2}(r K_2;n) = n-1$. We also show that for $n'=4r-2=R_3(r K_2)$ we have $\tilde{R}_{3}(r K_2;n') = 5r-4$.

Authors: Rakoyomamonjy Paul M. , Andriantsoa Sandrataniaina R.
Published: July 2021

We examine the enumeration of certain Motzkin objects according to the numbers of crossings and nestings. With respect to continued fractions, we compute and express the distributions of the statistics of the numbers of crossings and nestings over three sets, namely the set of $4321$-avoiding involutions, the set of $3412$-avoiding involutions, and the set of $(321,3\bar{1}42)$-avoiding permutations. To get our results, we exploit the bijection of Biane restricted to the sets of $4321$- and $3412$-avoiding involutions which was characterized by Barnabei et al. and the bijection between $(321,3\bar{1}42)$-avoiding permutations and Motzkin paths, presented by Chen et al.. Furthermore, we manipulate the obtained continued fractions to get the recursion formulas for the polynomial distributions of crossings and nestings, and it follows that the results involve two new $q$-Motzkin numbers.

Implementation of Energy Management in the Industrial Sectors
Authors: Beermann Carina
Published: July 2021

Global climate change, scarce energy resources and the increase in energy consumption make action urgently necessary. For everyday life, suggestions and legal regulations have been cre-ated to deal with the scarcity of resources and sustainability. In industry, guidelines and laws regulate the handling of resources such as electrical energy. Controlled energy policy and "voluntary" reduction of energy demand, especially in energy-intensive companies, play a de-cisive role and offer the approach for a possible resolution of this tension through the applica-tion of an energy management system. In order to achieve the goal of efficient energy man-agement, a constant individual review of the systems have to take place, for example with the help of the Plan-Do-Check-Act cycle at short intervals, in order to offer continuous. This pa-per examines whether the implementation of measures through standards, directives and regu-lations is sufficient to achieve the timely energy policy goals. Furthermore, it needs to be clari-fied whether energy management itself needs to be more in focus.

Published: July 2021

In clinical practice, body temperature is an acclaimed indicator for diagnosis and treatments amongst other follow - ups. This work studied the temperature distribution in deep-seated tissues using Penne’s bio-heat equation (PBE). The analytical solution of the PBE was formulated using the separation of variable technique. The resulting solution gives an expression for tissue temperature in organs that are located inside the body. This revealed that the tissue temperature is subject to changes in tissue thickness, the distance of tissue from the skin surface and other thermal properties of tissues under consideration.

data supplemented by archival data from Gaia eDR3 and Pan-STARRS. The stellar memberships are determined using a statistical method based on Gaia eDR3 kinematic data, and we found 204 members in SAI 44 while only 74 members are identified in SAI 45. The average distances to SAI 44 and SAI 45 are calculated to be 3670 ± 184 and 1668 ± 47 pc. The logarithmic age of the clusters are determined to be 8.82 ± 0.10 and 9.07 ± 0.10 yr for SAI 44 and SAI 45, respectively. The color–magnitude diagram of SAI 45 hosts an extended main-sequence turnoff (eMSTO). The apparent age spread is found to be similar to the apparent age spread predicted on the basis of the age spread and cluster age relation predicted by rotation models. This indicates that eMSTO is a stellar evolution rather than star formation phenomenon in SAI 45. We conclude that eMSTO in SAI 45 is mainly caused by the different rotation rates of stars as the SYCLIST synthetic population with different rotation rates was able to reproduce the observed eMSTO, and stars in the red part of the eMSTO were preferentially concentrated in the inner region, which again hints at different rotations being the reason for the extension in the upper MS. This finding supports the theory attributing the origin of eMSTO to the different rotations of eMSTO stars. The mass function slopes are obtained as −2.24 ± 0.66 and −2.58 ± 3.20 in the mass rages 2.426–0.990

The Sandwich Mode for Vertical Shear Instability in Protoplanetary Disks
Authors: Pfeil Thomas , Klahr Hubert
Published: July 2021

Turbulence has a profound impact on the evolution of gas and dust in protoplanetary disks (PPDs), from driving the collisions and the diffusion of dust grains, to the concentration of pebbles in giant vortices, thus, facilitating planetesimal formation. The vertical shear instability (VSI) is a hydrodynamic mechanism, operating in PPDs if the local rate of thermal relaxation is high enough. Previous studies of the VSI have, however, relied on the assumption of constant cooling rates, or neglected the finite coupling time between the gas particles and the dust grains. Here, we present the results of hydrodynamic simulations of PPDs with the PLUTO code that include a more realistic thermal relaxation prescription, which enables us to study the VSI in the optically thick and optically thin parts of the disk under consideration of the thermal dust-gas coupling. We show the VSI to cause turbulence even in the optically thick inner regions of PPDs in our two- and three-dimensional simulations. The collisional decoupling of dust and gas particles in the upper atmosphere and the correspondingly inefficient thermal relaxation rates lead to the damping of the VSI turbulence. Long-lived anticyclonic vortices form in our three-dimensional simulation. These structures emerge from the turbulence in the VSI-active layer, persist over hundreds of orbits and extend vertically over the whole extent of the turbulent region. We conclude that the VSI leads to turbulence and the formation of long-lived dust traps within ±3 pressure scale heights distance from the disk midplane.
Monte Carlo Investigation of the Ratios of Short-lived Radioactive Isotopes in the Interstellar Medium
Authors: Yagüe López Andrés , Côté Benoit , Lugaro Maria
Published: July 2021

Short-lived radioactive nuclei (SLR) with mean lives below ∼100 Myr provide us with unique insights into current galactic nucleosynthetic events, as well as events that contributed to the material of our solar system more that 4.6 Gyr ago. Here we present a statistical analysis of the ratios of these radioactive nuclei at the time of the early solar system (ESS) using both analytical derivations and Monte Carlo methods. We aim to understand the interplay between the production frequency and the mean lives of these isotopes, and its impact on their theoretically predicted ratios in the interstellar medium. We find that when the ratio of two SRLs, instead of the ratios of each single SLR relative to its stable or long-lived isotope, is considered, not only are the uncertainties related to the galactic chemical evolution of the stable isotope completely eliminated, but the statistical uncertainties are also much lower. We identify four ratios, 247Cm/129I, 107Pd/182Hf, 97Tc/98Tc, and 53Mn/97Tc, that have the potential to provide us with new insights into the r-, s-, and p-process nucleosynthesis at the time of the formation of the Sun, and need to be studied using variable stellar yields. Additionally, the latter two ratios need to be better determined in the ESS to allow us to fully exploit them to investigate the galactic sites of the p process.
Influence of the Bounds of the Hyperparameters on the Reconstruction of the Hubble Constant with the Gaussian Process

The cosmological model-independent method known as the Gaussian process (GP) has been widely used in the reconstruction of the Hubble constant H
0, and the hyperparameters inside GP influence the reconstructed result derived from GP. Different hyperparameters inside GP are used in the constraint of H
0 derived from GP with observational Hubble parameter H(z) data, and the influence of the hyperparameters inside GP on the reconstruction of H
0 with GP is discussed. The discussion about the hyperparameters inside GP and the forecasts for future data show that the consideration of the lower and upper bounds on the GP’s hyperparameters are necessary in order to get an extrapolated result of H
0 from GP reliably and robustly.
Le travail proto-therapeutique chez l’enfant
Authors: Merle Anaïs , Béraud Paul
Published: July 2021

L’enjeu élaboratif de l’expérience de la maladie en phase aiguë est fondamentale pour l’être en transition qu’est l’enfant. Pour lui permettre de symboliser ce qui n’est pas symbolisable en l’état , le clinicien est amené à soutenir une fonction « transitionnelle ». Ce travail psychique par paliers est initié à partir du proto-thérapeutique. Cet article propose de décrire la qualité de ce travail psychique réalisé en institution onco-pédiatrique qui participerait au maintien de l’activité symbolisante ainsi que de la prévention de la qualité et de l’intensité des effets d’un après-coup de l’événement à valence traumatique.
Voyage clinique au cœur de l’espace transitionnel
Authors: Michaux Danielle
Published: July 2021

En clinique infantile, l’intrication des troubles précoces dans la dynamique développementale et la multiplicité des modalités d’expression de l’enfant, du corps somatique au langage verbal, obligent le thérapeute à s’ajuster à de multiples transitions internes à la thérapie. Pour ce faire, les principes analytiques de la clinique présentée ici s’actualisent au sein d’un dispositif de psychomotricité relationnelle (Pratique Aucouturier). La partie théorique revient sur le paradigme de l’objet transitionnel de D.W.Winnicott, et sur les multiples formes intermédiaires de symbolisations, corporelles, primaires et secondaires. Celles-ci serviront de repères dans l’évolution thérapeutique. La partie clinique illustre ce « voyage dans l’espace transitionnel » auquel nous invitent les thérapies de deux enfants souffrant d’un trouble sévère du développement précoce. Des moments clés de leur évolution sont décrits.

In this paper, we investigate the following tropical climate model with fractional diffusion

   \begin{document}$ \begin{eqnarray} \left\{\begin{array}{ll} u_t+u\cdot\nabla u+\nabla p+\Lambda^{2\alpha}u+{\rm div}(v\otimes v) = 0,\\[1ex] v_t+u\cdot\nabla v+\nabla\theta+\Lambda^{2\beta}v+v\cdot\nabla u = 0,\\[1ex] \theta_t+u\cdot\nabla\theta+\Lambda^{2\gamma}\theta+{\rm div} v = 0,\\[1ex] {\rm div} u = 0,\\[1ex] ( u, v, \theta)(x,0) = ( u_0, v_0, \theta_0), \end{array} \right. \end{eqnarray} $\end{document}

where $ (u_0, v_0, \theta_0) \in H^s(R^n) $ with $ s\geq 1, n\geq 3 $ and $ {\rm div} u_0 = 0 $. When the nonnegative constants $ \alpha, \beta $ and $ \gamma $ satisfy $ \alpha\geq\frac{1}{2}+\frac{n}{4}, \ \alpha+\beta\geq 1+\frac{n}{2}, \ \alpha+\gamma\geq1+\frac{n}{2} $, by using the energy methods, we obtain the global existence and uniqueness of solution for the system. In the special case $ \theta = 0 $, we could obtain the global solution provide that $ \alpha\geq\frac{1}{2}+\frac{n}{4}, \alpha+\beta\geq1+\frac{n}{2} $ and $ (u_0, v_0)\in H^s(s\geq1) $, which generalizes the existing result.
Syncrétisme, purification et mission en Amérique latine

Le séminaire de cette année comportait, en principe, deux segments distincts. D’abord, une série de conférences sur le rôle de la sexualité dans la religion « populaire » latino‑américaine. Ensuite, un panorama du champ religieux indigène à Manaus (Amazonie brésilienne) basé sur mon enquête de terrain de l’été 2019.La pandémie de Covid-19 a considérablement réduit ce plan initial, ainsi que les nombreuses suspensions provoquées au préalable par la longue grève des transports publics à Paris.

Religions de l’Inde : études shivaïtes
Authors: Törzsök Judit
Published: July 2021

Nous avons proposé cette année d’offrir une initiation au śivaïsme, destinée principalement aux étudiants de master, à travers la lecture d’un texte du śivaïsme non dualiste du Cachemire, datant de la fin du xe ou du début du xie siècle : le Pratyabhijñāhṛdaya ou « Cœur de la reconnaissance » de Kṣemarāja. Pour notre conférence, nous avons divisé les deux heures en deux parties indépendantes, comme précédemment. Ainsi avons‑nous continué notre présentation du rituel du Siddhayogeśvarī-mata (« Enseignement des yoginī perfectionnées/puissantes », viie siècle environ) et la lecture du texte mythologique cachemirien du Haracaritacintāmaṇi (« Joyau magique de la geste de Śiva » du début du xiiie siècle).
Initiation à l’écriture ptolémaïque et lecture de textes des temples d’époque ptolémaïque et romaine :les légendes fonctionnelles de porte
Authors: Leroux Nicolas
Published: July 2021

Le premier cours a été consacré à une rapide présentation théorique de la spécificité de l’écriture hiéroglyphique de l’époque ptolémaïque. Nous avons ensuite travaillé le reste de l’année sur un corpus propre aux temples d’époque gréco-romaine : les légendes fonctionnelles de porte. Ce corpus présente en effet l’intérêt d’être constitué de textes relativement courts et d’un niveau de difficulté très variable : certains sont très élémentaires, d’autres beaucoup plus complexes.
Littérature, religion et idéologie :Mythes et modèles de récit sur les origines et les fonctions de la royauté et des savoirs dans les traditions cunéiformes
Authors: Masetti-Rouault Maria Grazia
Published: July 2021

Après avoir étudié l’épopée babylonienne de la création, l’Enuma Elish, suivant la même perspective de l’interprétation, au cours des séminaires de cette année nous avons lu et analysé deux textes littéraires mésopotamiens importants, qui discutent le premier de l’origine même de la royauté, et, le second, de la fonction et des pouvoirs de la connaissance, ainsi que de sa transmission, dans le cadre de la religion et de la culture cunéiformes du deuxième et du premier millénaire av. n. è. Il s’agit respectivement de la « légende d’Etana » et du « mythe d’Adapa », qui représentent sans doute des traditions parallèles, ou même alternatives, au discours et à l’idéologie développés, au cours du temps, par les inscriptions royales et par la littérature religieuse et rituelle.
La « fabrique » des puissances divines en pays grec : les noms, les corps, les pouvoirs
Authors: Pironti Gabriella
Published: July 2021

La représentation du divin dans les polythéismes antiques n’est pas réductible au seul anthropomorphisme, comme on le croit encore trop souvent, et nécessite d’être repensée à nouveaux frais. Sa stratégie s’articule en plusieurs registres (linguistique, narratif, cultuel, rituel, iconographique), chacun avec ses particularités expressives, qui répondent de manière variable et adaptée à une question fondamentale : comment faire de l’autre avec du même. Les recherches en cours interrogent ainsi sous l’angle de la pluralité et du relationnel les morphismes divers qui caractérisent la manière dont les Grecs ont « fabriqué » leurs dieux et/ou traduit en « artefacts » des puissances divines. Les noms, les corps et les pouvoirs qui leur sont attribués entretiennent un dialogue constant avec un savoir traditionnel, tout en se déclinant et se précisant en fonction de contextes spécifiques.

Histoire et doctrines du christianisme latin(Antiquité tardive)
Authors: Perrin Michel-Yves
Published: July 2021

Quelques récentes invitations à participer à des colloques où le directeur d’études a proposé des communications fondées sur des sources hagiographiques l’ont conduit à reprendre un dossier sur lequel il avait eu l’occasion de travailler naguère pour un mémoire de membre de l’École française de Rome. Le bollandiste Hippolyte Delehaye (1859‑1941) proposa de dénommer « légendier romain » « une collection uniquement composée des passions des saints martyrisés à Rome ou dans le prochain voisinage, et ensevelis dans les cimetières suburbains. Si nous ajoutons cette condition que les passions aient été rédigées à Rome même, nous obtenons un recueil homogène, qui se prête fort bien à une étude d’ensemble, et qui certes mérite le nom de légendier romain ».

Les activités de recherche et d’enseignement de l’année 2019‑2020 ont fait l’objet d’une mise en œuvre contrastée. Alors que le premier semestre s’est déroulé de façon habituelle, ce qui a permis aux étudiants et auditeurs de travailler autour du corpus textuel prévu au programme, le second semestre, qui a essentiellement correspondu à la période du premier confinement décrété en raison de la crise sanitaire du covid‑19, a fait l’objet d’une « réinvention » complète, non seulement des modalités d’enseignement, mais aussi des contenus.
