This article reflects the results of a study on the selection of promising lactobacilli antagonistic to Campilobacter jejuni, a strain that is the most common and more pathogenic for humans, carried out as part of a project to scientifically substantiate the use of new technologies in poultry feeding using special probiotic strains that increase productivity and obtaining poultry products of improved quality with the properties of functional food products. During the study, strains of lactic acid bacteria were obtained. The cultivation of strains of Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus fermentum, Lactobacillus reuteri, Lactobacillus plantarum, Lactobacillus plantarum was carried out on liquid and agarized nutrient media MRS at 370С for 24 hours. In vitro antagonistic studies were performed using the two-way antagonistic method on a wide range of indicator crops. Since there is evidence of a specific mechanism for the manifestation of the antagonistic activity of lactobacilli to gram-negative and gram-positive bacteria, we used test strains of both groups of bacteria. The antagonistic activity of the studied cultures against pathogenic and opportunistic bacteria was determined by the zone of growth inhibition of indicator strains around the colonies of individual strains of lactobacilli and their consortium (in mm). Priority clinical isolates isolated from birds with intestinal infections were used as indicator cultures: Proteus vulgaris, Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Campylobacter jejuni and Campylobacter jejuni ATCC strains 33560. During the study, most bacterial strains of the genus Lactobacillus were highly antagonistic its activity against indicator strains. The most sensitive to the inhibitory effect of lactobacilli were E. coli, Campylobacter jejuni, S. typhimurium and P. vulgaris. The research results showed that the strain L. plantarum ATCC 8014 exhibits a more pronounced antagonistic activity than other strains of lactobacilli.

Software-Defined Networking (SDN) is an evolving algorithm which is depended upon the computer network transformation. In SDN, Bandwidth Utilization is a critical aspect to enhance network performance. To obtain the accessible bandwidth for the Mobile Broadband over SDN and in sequence enhance the accessible Mobile Broadband is the main objective. A significant characteristic is ABW (ABW), having a robust influence on a wide range of applications. However, this metric is very complex to estimate using traditional or conventional methodologies. The Traditional Bandwidth Estimation Technique has limited accuracy along with huge convergence time. The Estimation Time cannot be predicted as it depends on the existence of appropriate traffic produced through any third-party applications. 50% of Systematic Errors are not uncommon. In order to overcome the above-mentioned issues, in this paper, a novel approach is introduced for the estimation of ABW over SDN using three different scenarios. In which, SFC constraint shortest distance algorithm is employed for solving the classical max-flow issue that occurs in multiple scenarios while evaluating the ABW. The experiment result is carried out using Mininet testbed for network emulation and Floodlight as an SDN controller. Some of the interesting cases are considered, and the ABW is measured for the proposed software-defined network and compared with the existing traditional network and existing software-defined network.

This paper presents an adaptive PI based two control strategies of Dynamic Hysteresis Torque Band (DHTB) for improving flux regulation at low speed and zero speed in lookup table based Direct Torque Control (DTC) of an Induction Machine (IM). This is achieved by varying the band value of torque dynamically but it is limited with flux error range. With the conventional HTB based DTC, at low and zero speed, the regulation of flux will not be good. To overcome this drawback, a small alteration in the structure is done, i.e., DTHB, thus retaining the simplicity of DTC algorithm. The performance is verified by varying the speed at low values. At low speeds of IM, the flux regulation and the speed is improved with adaptive PI controller based DHTB-II compared to DTC with DHTB-I and DHTB-II.

In this thesis, an innovative idea of watermarking technique is proposed based on Gram Schmidt orthogonalization. This technique can provide robust and improved imperceptible images for safeguarding the copyrights. Implanting process in this watermarking system uses certain recurrence locales of DCT to such an extent that inclusion of watermark bits causes the least picture contortion. In this way, the Gram-Schmidt orthogonalization is resolved to insert the watermark in the original picture for obtaining excellent picture quality. During the amendment of watermark into the bits having the specific frequency of the picture, bits involved in watermarking are not straightforwardly embedded into the recurrence coefficient; preferably, there is need to adjust the specific coefficients of the picture that depends on certain principles that builds the watermarking picture. The frequencies which are inserted are controlled by utilizing changed entropy discovering substantial excess territories. Moreover, the watermark is mixed before inserting to give an extra security. So as to confirm the proposed procedure, our strategy is tried. The trial results demonstrate that our procedure accomplishes higher imperceptibility and strength than the existing techniques. The watermark extraction gives more expected results to picture quality after various variety of attacks.

Kontekstualisasi Filsafat Politik al-Fârâbî dalam Pemikiran Politik Modern
Authors: Muthhar Moh. Asy’ari
Published: November 2019

The article describes that in light of al-Madînah al-Fâḍilah, al-Fârâbî idealized the relationship between state and its citizens based on ethical values. This is in order to create a society who recognize the truth and enforce it in the form of cooperation with the state to build mutual prosperity. According to al-Fârâbî, society is a pivotal element of the creation of state. Within nation-state realm, the members of society must positively demonstrate their contribution based on their respective capability. Al-Fârâbî called, in addition, for the existence of freedom (al-ḥurriyah) for all people. The task of a state leader is to provide his members guidance to justly stride on right path in accordance with religious doctrines and to prevent them from going astray from the initial objective of state creation, i.e. triumphing happiness within the world and the hereafter. Al-Fârâbî’s political thought has great influence in the next development of the modern democracy. The article indicates that al-Fârâbî’s concept of freedom has been subsequently reinterpreted by the next Muslim scholars emphasizing that the concept of freedom he deemed is not a borderless freedom.
Fiqh Prioritas sebagai Instrumen Ijtihâd Maqâṣidî Perspektif Yûsuf al-Qarâḍawî dan Urgensinya di Era Kontemporer
Authors: Jauhari Nashrun
Published: November 2019

The article attempts to analyze Fiqh of Priority as an instrument of ijtihâd maqâṣidî from Yûsuf al-Qarâḍawî’s perspective and its significance within the contemporary era. The position of the Fiqh of Priority within the study of Islamic law is a part of the conceptual developments of ijtihâd which is based on maqâṣid al-sharî‘ah and has been oriented into Fiqh of Daʻwah. The Fiqh of Priority along with its principles can be functioned as a reference in stipulation of the Islamic law (ijtihâd al-ah}kâm). This is because the Fiqh of Priority is built on the priority values revealed in al-Qur’ân and mentioned in H{adîth as well as based on the concept of tadarruj al-ah}kâm (gradation of stipulation of the Islamic law) during the Prophet Muhammad’s lifetime. Epistemo-logical framework of the Fiqh of Priority consists of three main principles, i.e. the principles of gradation in the Islamic law (al-fiqh bi marâtib al-a‘mâl), the principles of attitude towards the reality of law (fiqh al-wâqi‘ li al-ah}kâm), and the principles of dealing with contradiction between arguments or reasoning between the stipulation of law and social reality

Authors: Markina Iryna Anatoliivna , MARCHYSHYNETS Serhii Mykolaiovych
Published: November 2019

Introduction. The main catalyst for effective transformations in the industrial sector of the economy is innovation and investment policy, which aims to increase the potential, namely the capacity of the manufacturing sector of the Ukrainian economy. The innovation and investment potential closely reflect the objectively existing possibility of socio-economic development of the human system.
The purpose of the article is to clarify the basic principles and approaches that reflect the innovation and investment potential and the essence of innovation and investment development.
Results. The state ideology in the field of innovation and investment policy is considered. A generalization of the concept of “development” of the philosophical point of view is presented. The decisive role of development in understanding the essence of everything is proved. The vector of development in terms of its regressive or progressive manifestation is considered. It is determined that the stages of development are the stages of system change, which include: appearance, upward stage of development, maximal development or maturity, regressive changes or downward stage, disintegration and death. The tendency of differentiation in socio-economic systems is determined. The essence of “becoming” as a stage in the system development is considered. The essence of the system's maturity is revealed. External and internal sources of system development are considered. On the basis of the theoretical generalization, the key properties of the concept of “development” are given: it acts as a form of constant movement forward from simple to complex form; the degree of development is determined by the influence of external and internal factors; the way of development of the system is determined by its basic motives, the degree of recognition by the system of objectively existing reality; development is possible if it’s provided by the quantitative parameters of the end goal; the form of its implementation is cyclical or spiral; analysis of development must be carried out in two directions of research: in the material and spiritual worlds. The definition of “innovation” is given. The essence of scientific and technological progress as a basis of economic development is considered and the vision of leading scientists-economists on this phenomenon is presented. Quantitative estimates of the impact of innovative GDP growth are provided. The quantitative contribution of various factors of economic growth of a market economy is given.

Giant Planet Occurrence within 0.2 au of Low-luminosity Red Giant Branch Stars with K2
Authors: Grunblatt Samuel K. , Huber Daniel , Gaidos Eric , Hon Marc , Zinn Joel C. , Stello Dennis
Published: November 2019

Every Sun-like star will eventually evolve into a red giant, a transition which can profoundly affect the evolution of a surrounding planetary system. The timescale of dynamical planet evolution and orbital decay has important implications for planetary habitability, as well as post-main-sequence star and planet interaction, evolution, and internal structure. Here, we investigate these effects by estimating planet occurrence around 2476 low-luminosity red giant branch (LLRGB) stars observed by the NASA K2 mission. We measure stellar masses and radii using asteroseismology, with median random uncertainties of 3.7% in mass and 2.2% in radius. We compare this planet population to the known population of planets around dwarf Sun-like stars, accounting for detection efficiency differences between the stellar populations. We find that 0.49% ± 0.28% of LLRGB stars host planets larger than Jupiter with orbital periods less than 10 days, tentatively higher than main-sequence stars hosting similar planets (0.15% ± 0.06%). Our results suggest that the effects of stellar evolution on the occurrence of close-in planets larger than Jupiter are not significant until stars have begun ascending substantially up the red giant branch (≳5–6 R
⊙).

Published: November 2019

Using data from the MOSFIRE Deep Evolution Field (MOSDEF) survey, we present a census of active galactic nucleus (AGN)–driven ionized outflows in a sample of 159 AGNs at 1.4 ≤ z ≤ 3.8. The sample spans AGN bolometric luminosities of 1044–47 erg s−1 and includes both quiescent and star-forming galaxies extending across 3 orders of magnitude in stellar mass. We identify and characterize outflows from the Hβ, [O iii], Hα, and [N ii] emission line spectra. We detect outflows in 17% of the AGNs, seven times more often than in a mass-matched sample of inactive galaxies in MOSDEF. The outflows are fast and galaxy-wide, with velocities of ∼400–3500 km s

and spatial extents of 0.3–11.0 kpc. The incidence of outflows among AGNs is independent of the stellar mass of the host galaxy, with outflows detected in both star-forming and quiescent galaxies. This suggests that outflows exist across different phases in galaxy evolution. We investigate relations between outflow kinematic, spatial, and energetic properties and both AGN and host galaxy properties. Our results show that AGN-driven outflows are widespread in galaxies along the star-forming main sequence. The mass-loading factors of the outflows are typically 0.1–1 and increase with AGN luminosity, capable of exceeding unity at

. In these more luminous sources, the ionized outflow alone is likely sufficient to regulate star formation and, when combined with outflowing neutral and molecular gas, may be able to quench star formation in their host galaxies.
UVIT Open Cluster Study. II. Detection of Extremely Low Mass White Dwarfs and Post–Mass Transfer Binaries in M67
Authors: Jadhav Vikrant V. , Sindhu N. , Subramaniam Annapurni
Published: November 2019

A detailed study of the UV-bright stars in the old open star cluster M67 is presented based on the far-UV observations using the Ultra Violet Imaging Telescope (UVIT) on ASTROSAT. The UV and UV–optical color–magnitude diagrams (CMDs), along with overlaid isochrones, are presented for the member stars, which include blue straggler stars (BSSs), triple systems, white dwarfs (WDs), and spectroscopic binaries. The CMDs suggest the presence of excess UV flux in many members, which could be extrinsic or intrinsic to them. We construct multiwavelength spectral energy distributions (SEDs) using photometric data from the UVIT, Gaia DR2, Two Micron All Sky Survey, and Wide-Field Infrared Survey Explorer surveys, along with optical photometry. We fitted model SEDs to seven WDs and find that four of them have mass >0.5 M
⊙ and cooling age of less than 200 Myr, thus demanding BSS progenitors. SED fits to 23 stars detect extremely low mass (ELM) WD companions to WOCS2007, WOCS6006, and WOCS2002 and a low-mass WD to WOCS3001, which suggest these to be post–mass transfer (MT) systems. Twelve sources with possible WD companions need further confirmation. Nine sources have X-ray and excess UV flux, possibly arising out of stellar activity. This study demonstrates that UV observations are key to detecting and characterizing the ELM WDs in nondegenerate systems, which are ideal test beds to explore the formation pathways of these peculiar WDs. The increasing detection of post-MT systems among BSSs and main-sequence stars suggests a strong MT pathway and stellar interactions in M67.

Balzac et l’Angleterre : une amitié armée ?
Authors: Farrant Tim
Published: November 2019

Balzac et l’Angleterre : sujet bizarre mais incontournable, qui s’attache à un pays, et un peuple, qui est à la fois un grand absent dans la vie de Balzac et une grande présence dans son œuvre. Cet article sert de lever de rideau pour les actes spectaculaires qui suivent, eux-mêmes traces d’une rencontre heureuse à Oxford au printemps 2018 et reflets fidèles des multiples incarnations et conceptions de Balzac en Angleterre et de l’Angleterre dans Balzac. Évoquant dans un premier temps les personnages anglais de Balzac et sa réception britannique contemporaine, il se penche ensuite sur les premières traductions, à l’occasion américaines, parfois malheureuses, avant de se tourner vers l’essor de la critique savante à partir du début du vingtième siècle. Cette entente désormais plus que cordiale influe toujours sur notre époque, non seulement dans le domaine universitaire, mais aussi dans les plus hautes sphères de l’intelligence et de la politique. Car la revendication première de Balzac, présente dans ses lectures précoces de philosophes, se traduit par le biais d’un florilège de penseurs et de romanciers britanniques dont le premier est un trouvère écossais et son rival un homme de théâtre mondial. Scott et Shakespeare forment et informent l’œuvre de Balzac, mais aussi l’appréciation britannique de cette œuvre : c’est à l’aune de ces colosses qu’on mesurera Balzac et qu’on lui taillera une place souveraine dans la mythologie littéraire britannique et cosmopolite. Si la fortune et la réputation critique de Balzac à son époque n’étaient pas toujours des plus heureuses, ces dissonances sont l’écho de la discordance entre des réactions conservatrices, s’inspirant d’une morale traditionaliste, et l’admiration d’une élite de romanciers et d’artistes qui sera de plus en plus dominante et qui portera le nom et la création de Balzac par le biais de l’anglais dans la critique et dans la traduction, aussi bien que le français, partout dans le monde. Ses émissaires se nomment Collins, Wilde ou James, mais les reflets sont symétriques : en témoigne le rôle de l’étude littérature anglaise de Taine dans les écrits de Stephen sur Scott et Balzac, ou le courrier Trans-Manche d’un Mortimer ou d’un Anthony Powell. Cette danse de la vie humaine n’est pas près de finir, Balzac et l’Angleterre se contemplant des deux côtés du détroit dans une appréciation plus vive et mutuelle.
Le mystère des lords balzaciens
Authors: Baron Anne-Marie
Published: November 2019

De Lord R’hoone à Lord Grenville ou Lord Dudley, les lords balzaciens, qu’ils soient pseudonymes ou personnages, sont des êtres fictifs dont on a renoncé à chercher les modèles. Ce qui nous importe, c’est le rôle qu’ils jouent, leur fonction dans l’économie narrative et leur origine dans l’écriture de La Comédie humaine . Sont-ils des espèces sociales, des puissances politiques, des personnages allégoriques, des utilités narratives ou des images paternelles que le romancier débutant dénonce et dans lesquelles il se projette ? Entre génétique, stratégie romanesque, exploration des fantasmes et herméneutique romanesque, tel est le questionnement qui fait l’objet de cet article.
Balzac et l’Angleterre. Du commerce de l’opium et du thé
Authors: Bui Véronique
Published: November 2019

Quelque vingt ans avant Hugo, Balzac, par voie de presse, dénonce les exactions de l’Angleterre en Chine. En 1842, dans son compte rendu de l’album illustré de Borget, La Chine et les Chinois , le romancier prend position pour les Chinois contre les Anglais dans le conflit de la première guerre de l’opium. Il s’insurge devant l’immoralité du commerce du thé en échange d’une substance mortifère et le laissez-faire du gouvernement français. Toutefois, cet engagement relève moins d’une réelle sinophilie que de la volonté de préserver intacte l’image fantasmatique de la puissante Chine, Empire du Milieu, dirigé par un autocrate à l’instar de cet autre empire oriental dont le thé est la boisson quotidienne : l’empire russe. La diatribe de Balzac contre l’expansionnisme anglais du commerce de l’opium et du thé sert tout à la fois son rêve de Chine et son désir de défendre les intérêts de la grande Russie.
Les produits importés d’Angleterre : traçabilité d’une « idée heureuse »
Authors: Gautier Jean-Jacques
Published: November 2019

Aborder, dans son entier, l’œuvre de Balzac sous l’angle des produits importés anglais permet, certes d’une façon fortuite et malgré leur laconisme, d’enrichir les niveaux de lecture où ils apparaissent comme éléments d’un étranger omniprésent. L’exploitation persistante de certains d’entre eux les constitue en accessoires, qui structurent l’intrigue quand ils ne sont pas repères temporels. Les occurrences uniques soulignent toute la valeur de l’anglophilie, et par contraste, l’apport des produits exploités en chaîne littéraire formant, selon des modules déclinés, les caractéristiques d’une altérité souvent féminine. Importés d’une terra incognita d’outre-Manche, ces produits sont soumis à la libre alchimie créatrice de l’écrivain, car disposés et agglomérés selon une perspective qui peut se qualifier, selon l’expression balzacienne, d’« idée heureuse », selon ce système d’appropriation et de restitution, propre, génétiquement parlant, à Balzac.
Balzac et le roman gothique anglais
Authors: Sprenger Scott
Published: November 2019

Cet article tente de démontrer que l’intérêt précoce de Balzac pour la littérature gothique britannique a façonné sa philosophie de la subjectivité post-révolutionnaire. Tandis que la conscience républicaine – développée et promue par Victor Cousin – était fondée sur un principe de volonté rationnelle, la tradition gothique britannique considérait la conscience comme divisée intérieurement et animée par des sentiments et désirs catholiques déplacés. Nous trouvons des traces de ce modèle gothique de la conscience divisée dans La Comédie humaine , qui explique les comportements mystérieux de ses personnages et anticipe de manière étonnante une branche de la philosophie anglo-américaine du xxi e  siècle appelée « post-séculière ».
Le Nabab anglais de Balzac
Authors: Paine Jonathan , Ploix Cedric
Published: November 2019

À l’apogée mélodramatique de Splendeurs et misères des courtisanes de Balzac, le lecteur trouve l’un des épisodes les plus curieux du roman : la métamorphose de Peyrade, policier, père de famille et âme pervertie, en pastiche d’un Nabab anglais. Cet article soutient que l’épisode en question marque un tournant décisif, non seulement dans l’intrigue de Splendeurs et misères , mais également dans le rapport qu’entretient Balzac avec ses lecteurs. L’excès mélodramatique dont il se sert dans cet épisode lui permet à la fois de rivaliser avec Sue et de parodier la soumission de ce dernier au sensationnel. En amenant les lecteurs aux limites de la vraisemblance, parfois en mettant leur crédulité à rude épreuve, Balzac, en ce début de l’ère du roman-feuilleton, s’essaye à explorer divers ressorts de la fiction en prose. Cet article pose le Nabab de Peyrade comme le symbole des excès auxquels la presse anglaise s’était adonnée depuis l’avènement du journalisme populaire, et comme une figure toute trouvée pour les lecteurs toujours plus avides d’intensité dans le sensationnel.
Les éditions anglaises de Balzac. 1850-1900
Authors: Rapoport Michel
Published: November 2019

Si, de son vivant, quelques textes de Balzac sont publiés dans des revues britanniques, c’est surtout à partir des années 1860 que se multiplient les éditions anglaises de ses œuvres. Ce sont d’abord quelques romans et nouvelles qui sont traduits. Mais à la fin du siècle, trois intégrales de La Comédie humaine apparaissent sur le marché britannique, éditées par de grandes maisons, Dent, Macmillan, Caxton. Les deux dernières publient en fait des traductions en provenance des États-Unis. Seule l’édition Dent, publiée sous la direction de l’universitaire balzacien Saintsbury et traduite par Ellen Marriage, Clara Bell, la seule traductrice professionnelle, et Rachel S. Scott, est anglaise. Pendant longtemps, il y eut une grande méfiance à l’égard de Balzac de la part d’une critique qui voyait en lui un auteur obscène, immoral. Il faut attendre les années 1890 et l’édition Dent pour que cet auteur, jugé difficile à traduire, soit enfin accessible et reconnu par la critique.
« La catastrophe de Balzac » : le génie, l’échec et l’image de Balzac chez Henry James
Authors: Paraschas Sotirios
Published: November 2019

L’un des portraits de Balzac le plus souvent dessiné par ses critiques contemporains et ultérieurs est celui d’un génie qui échoue. Dans la présente étude, je montre que ce portrait, repris par Henry James dans les cinq essais qu’il consacra à l’auteur de La Comédie humaine de 1875 à 1913 (ainsi que, de façon indirecte, dans son conte La Madone de l’avenir , paru en 1873), est tiré du Chef-d’œuvre inconnu et moulé sur le personnage de Frenhofer. Les liens entre Le Chef-d’œuvre inconnu et l’image de Balzac chez James sont préfigurés, voire préparés, dans nombre d’ouvrages critiques et biographiques portant sur Balzac, dont au moins deux étaient bien connus de James, à savoir l’essai de Taine sur Balzac (1858) et les souvenirs de Léon Gozlan, Balzac en pantoufles (1856) et Balzac chez lui (1862) (réunis en 1886 dans Balzac intime ).
Dissonances et consonances des traductions de « La Cousine Bette » en anglais
Authors: Aubin Marie-Christine
Published: November 2019

Patrick O’Neill présente dans ses ouvrages Polyglot Joyce (2005) et Kafka Translated (2014) une théorie séduisante qui donne à chaque nouvelle traduction d’une œuvre ou d’un auteur un rôle d’extension du texte original et de ses interprétations, lesquels constituent un macrotexte polyphonique multiforme et multilingue qui inclut tout autant les dissonances (interprétations erronées, traductions fautives) que les consonances (interprétations neuves et convaincantes, traductions judicieuses). À partir de quelques exemples tirés des traductions/adaptations de La Cousine Bette en anglais, nous tâcherons de distinguer ces consonances et ces dissonances et, ce faisant, nous nous demanderons quel rôle celles-ci jouent dans le macrotexte balzacien.
Balzac – Chadenat – Cendrars : « strange encounters »
Authors: Vanoncini André
Published: November 2019

Malgré leurs places bien distinctes dans l’évolution historique et littéraire, Balzac et Cendrars partagent de nombreux intérêts. Ainsi leur vision de l’Angleterre révèle, dans une large mesure, une approche typiquement continentale des relations franco-britanniques. Et pourtant, Cendrars, qui développe son œuvre plus d’un demi-siècle après son prédécesseur, traite la problématique en adoptant une perspective nouvelle, marquée par son époque. Il l’inscrit notamment dans un cadre plus large de façon à en dialectiser d’importants aspects.
La radio et le texte refondu
Authors: Watts Andrew
Published: November 2019

L’histoire des adaptations de l’œuvre de Balzac est longue et palpitante. En Grande-Bretagne, des versions radio de textes de Balzac ont souvent figuré dans les productions de pièces radiophoniques de la BBC, avec des adaptations de La Cousine Bette (2000), La Rabouilleuse (2008) et Eugénie Grandet (2014). Vu l’intérêt récurrent de la BBC pour La Comédie humaine , on doit également à cette station l’une des adaptations radiophoniques les plus innovantes et inhabituelles jamais réalisées de l’œuvre de Balzac, à savoir The Wild Ass’s Skin Reloaded (2011), une réinvention de La Peau de chagrin , écrite par Adrian Penketh et mise en scène par Toby Swift. Comme le soutient cet article, la pièce radiophonique de Penketh s’impose comme un drame intrigant qui nous invite à considérer l’adaptation comme un processus de circulation dans lequel le texte d’origine gagne en valeur et en résonance par sa refonte dans un contexte culturel différent.
Albert Savarus : « cet obscur objet du désir »
Authors: Lacombe Anne
Published: November 2019

Dans la première partie de notre étude ( L’Année balzacienne 2018 ), nous interrogions les modalités d’une présence problématique d’un héros entrevu et comme frappé d’impuissance jusqu’à son effacement final et symbolique. Il nous faut à présent explorer les enjeux de cette dissolution à l’aune des tensions significatives entre le monde sublimé de la Suisse et de l’Italie, patrie de l’Idéal et l’âpre Province du Réel bisontin qui affectent le personnage et les figures féminines qui lui sont attachées. Les rapports de ces personnages à ces mondes opposés, tant en termes d’appartenance que sous l’angle du désir, offrent, dans leur complexité et leur ambivalence – parallélismes, croisement, inversions – de riches interprétations.
Éthiques et handicaps
Authors: Salbreux Roger
Published: November 2019

L’éthique et la morale constituent-elles des notions identiques ou différentes ? La situation de handicap majore-t-elle les problèmes éthiques, en produit-elle davantage ou ne fait-elle que grossir les questionnements éthiques de tout un chacun ? Le changement de statut de la personne handicapée dans la société a-t-il modifié le regard de cette dernière sur cette condition particulière et par conséquent l’éthique des conduites à l’égard de ces personnes ? À l’aide de quelques situations cliniques empruntées à la fœtologie, à la réanimation néonatale, à l’annonce du handicap, à l’éducation thérapeutique et aux heurs et malheurs de l’inclusion, l’auteur s’efforce de montrer la complexité de ce problème.
