Objective. Novel inflammatory indices are a potential substitute for traditional markers which their correlation and clinical application in different autoimmune diseases are still in question. In this study, we evaluated the association of platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and systemic immune-inflammation index (SII) with systemic lupus erythematosus (SLE) activity. Methods. We included 103 SLE patients in our study, compared to a matched pair of 103 healthy individuals. A blood sample was drawn to measure SII, PLR, NLR, C-reactive protein, erythrocyte sedimentation rate, autoantibodies, and complement levels. Independent sample t-test, chi-square, and Mann-Whitney U test were implemented for variables as appropriate. Linear regression was used to evaluate the factors that predict SLE activity. Results. Our study revealed that NLR, PLR, and SII between SLE patients and the control group were significantly different. SII and NLR were correlated with renal manifestations of SLE. PLR was correlated with SLEDAI, and an independent factor of SLE activity after adjusting for multiple factors, but not NLR and SII. Conclusion. We demonstrated that only PLR was an independent predictor of SLE activity. This may suggest that NLR and SII are more nonspecific inflammatory markers, compared to PLR being prognostic of SLE activity.

Plant compounds such flavonoids, terpenoids, polyphenols, enzymes, and alkaloids are used as reducing agents in eco-friendly titanium dioxide nanoparticle manufacturing. In the current investigation, titanium oxide was converted into titanium dioxide nanoparticles with the application of a lemon extract. Amazingly, the process was also cheap, eco-friendly, and easy to implement. Seeing the white fluid change to a pale yellowish white allowed us to visually confirm that the nanoparticles had been successfully created. Transmission electron microscopy (TEM) and ultraviolet-visible spectroscopy were employed for further characterization. Nanoparticles of titanium dioxide were measured to be between 30 and 45 nm in size. In the DPPH assay, a titanium dioxide nanoparticle concentration of 50 L was shown to be optimal for antioxidant activity. The results of the bovine serum albumin denaturation experiment validated the green produced nanoparticles' dose-dependent anti-inflammatory effect. Consequently, the green synthetic titanium dioxide nanoparticles have great potential as an anti-inflammatory and antioxidant in future medicinal applications.

Published: January 2024

INTRODUCTION. More than 36 million people die from NCDs each year (63 % of deaths worldwide), of which 14 million people die prematurely, that is, before the age of 70 years, the majority could be prevented through the organization of continuity and consistency in the organization of health care. In 2021, based on the experience of developed countries of the world, a standard form of the «Algorithm» for patient care in an outpatient setting after hospital treatment was developed (including stages of observation, periods of clinical examination and mechanisms for organizing rehabilitation services, including diet, exercise therapy and sanatorium-based treatment). A study was conducted among patients diagnosed with coronary heart disease regarding the organization of continuity and consistency of rehabilitation services after inpatient treatment in conditions outpatient clinics in the Yakkasaray district of Tashkent.
AIM. To study the practice of applying the organization of continuity and consistency in the provision of medical care for NCDs in Uzbekistan.
MATERIALS AND METHODS. The materials were the results of a study of patients diagnosed with coronary heart disease in 2021 — 537 patients and in 2022 — 596 patients in the Yakkasaray district of Tashkent. Retrospective, analytical research methods were used for the analysis.
RESULTS. In 2021, a total of 537 patients diagnosed with coronary heart disease received inpatient treatment in family clinics of the Yakkasaray district, and only 195 (36 %) brought discharge summaries, 195 (100 %) patients were taken for treatment as prescribed by doctors at outpatient clinics — control, 173 (88 %) 10 (5 %) underwent ECG and EchoCG, respectively, and 12 (6 %) patients were sent to sanatorium treatment. In 2022, in family clinics of the Yakkasaray district, a total of 596 patients received inpatient treatment, of which 535 (89 %) brought a discharge summary of inpatient treatment, 535 (100 %) patients were taken for D-control as prescribed by doctors from outpatient clinics, 535 (100 %) active patronage was established with an explanation of proper nutrition, physical activity, physiotherapeutic treatment, and 84 (16 %) patients were sent to sanatorium treatment.
CONCLUSION. Continuity and consistency are important in improving the quality of medical care, so healthcare organizers need to introduce new methods and improve existing approaches to improve the relationship between inpatient and outpatient clinics.

Authors: Zidan Mohamed S. , Elsayed Marwa M. , Ismail Azza F. , Ahmed Sandra M. , Obaya Hany E.
Published: January 2024

INTRODUCTION. Post-stroke dysphagia is reported in 30–50 % of stroke population. It increases mortality rate and leads to serious complications such as expiratory muscle affection which is a major cause of defective swallowing and ineffective airway protection. Expiratory muscle strength training (EMST) and functional electrical stimulation (FES) are recommended techniques to improve expiratory muscles performance.
AIM. To compare the effect of EMST to that of FES on pulmonary and swallowing functions in acute stroke patients.
MATERIAL AND METHODS. Seventy-two patients with post-stroke dysphagia were divided into two groups. Both groups received traditional dysphagia treatment. In addition, the first group received EMST and the second received neck and abdominal FES. Pulmonary functions were measured before and after in form of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio and peak expiratory flow (PEF), and arterial blood gases (ABG) while the Gugging Swallowing Scale (GUSS) was used as an indicator of swallowing function results of both groups were compared after one month of treatment.
RESULTS. The post-treatment GUSS, FVC, FEV1 and PEF of the EMST group showed more significant increase compared to the FES group (p 0.05) with no significant differences in FEV1/FVC (p 0.05). Regarding ABG, there was more significant decrease in PaCO2 and HCO3 of EMST group compared to FES group (p 0.01).
CONCLUSION. EMST was more effective than FES when it comes to improving expiratory and swallowing functions in patients with post-stroke dysphagia.
Skeletal Muscle Apoptosis: a Debated Issue Now Well Resolved in Favor of the Padua School of Skeletal Muscle. A Review
Authors: Carraro Ugo
Published: January 2024

In my research I have often found myself on the wrong side of the flow of international beliefs. I have generally been wrong and wasted my time and resources and my co-workers, but, sometimes, we have been on the right side. Such was the case with the role of apoptosis, also known as the programmed cell death, in biology and pathology of skeletal muscle tissue. Indeed, our original and pioneering findings have led to a change of direction in this research area. This role had been dismissed by the leading myologists, but using electron microscopy and molecular analyzes we demonstrated that accepted markers of apoptosis were present in mouse skeletal muscles two days after one night of voluntary running (up to 5 km during the first night). In a few years we have extended this fundamental observation to other experimental models in vivo and in vitro and in human cases of muscular dystrophies. In this paper I will give an overview of how the story began, but I must emphasize that Marzena Podhorska-Okolow and Marco Sandri deserve the highest praise for their most notable roles in the beginning and after, the roles and services that are still notable today.

Muito além das facções: uma agenda de pesquisas sobre ilegalismos, violência e Estado na Amazônia
Authors: Candotti Fabio Magalhães , Melo Flávia
Published: January 2024

Desde 2017, após um massacre em uma unidade prisional, a presença de facções criminosas na Amazônia tornou-se objeto de interesse nacional, alimentado, nos anos seguintes, por outros eventos e pesquisas que aproximaram segurança pública, defesa nacional, proteção social e meio ambiente. Este ensaio problematiza esse interesse em dois movimentos, sustentado por pesquisas realizadas desde a década passada no estado do Amazonas. O primeiro oferece uma crítica à maneira colonialista como as violências locais são pensadas por discursos exógenos à região, sobretudo ao diagnóstico da “ausência de Estado” e da “expansão das facções”. Em seguida, apresentamos um conjunto de problemas de pesquisa que guiam nossos trabalhos, a respeito dos mercados ilegais, das formas de presença de estado e das violências que incidem sobre corpos e populações indígenas, negras e periféricas. Ao fim, defendemos a necessidade de investimentos em pesquisa sobre esses temas na região e a importância de uma produção de conhecimentos aliançada a movimentos sociais.

„Állampolgárság 30”, avagy a magyar állampolgárságról szóló törvény elmúlt három évtizede
Authors: Mágó Barbara
Published: January 2024

Aim: Act LV of 1993 on Hungarian Citizenship celebrates the 30th anniversary of its entry into force. The purpose of this study is to pay tribute to the past three decades of the law and to describe the path leading to the adoption of the current law and the main changes that have taken place since then. The author also attempts to examine changes in citizenship law in the present days.Methodology: In presenting the path leading to the adoption of the current Citizenship Act, the author also drew on the work of the preparatory legislative process, and in describing the legislation and the changes that have taken place in the meantime, he has not only drawn on the available literature but also recorded his own professional experience, and after examining international citizenship jurisprudence, he has formulated innovative ideas.Findings: The new and modern legislation, reflecting the reality of a democratic, constitutional state and the rule of law, has fundamentally changed most of the legal procedures for citizenship. Its main values were the abolition of the deprivation of citizenship, the completion of the necessary moral reparation through the institution of acquiring citizenship by declaration, and the rational reorganisation of the naturalisation system based on international models. The most significant and comprehensive changes were made following the decision to adopt the so-called simplified naturalisation procedure, which in 2011 made the conditions for naturalisation significantly more favourable for descendents of former Hungarian nationals. The legislation, which has been amended several times with minor changes and is thirty years old this year, has therefore weathered the storms of time. Nevertheless, it is necessary to bear in mind that, in the context of migration and related social processes in the world, especially in Europe, with regard to certain persons with a migration background who may pose a risk to national security. The role and system of citizenship law is changing across the continent, or rather moving in a sanctioning direction.Value: The study praises the timelessness of the basic principles of Act LV of 1993 on Hungarian Citizenship, while at the same time presenting the main changes in the law over the past thirty years. It also aims to draw attention to international trends in which the challenges posed by migration can be addressed at the level of citizenship law.

Aim: The aim of the study is to present a solution, currently operating as a group of experts, with the mission to support the activities of customs professionals at the EU’s eastern and south-eastern external land borders. The experts group provide support in the areas of risk management, customs controls, equipment and procurement, training on different topics, performance measurement and evaluation, and cooperation with other border services. The relevance of the expert group is further enhanced by the fact that it is occasionally mentioned in publications analysing the reform package of the Customs Union.Methodology: In addition to the analysis of the relevant literature, the secondary research has examined EU documents related to the creation of the expert group or its activities during the project periods. The comparative analysis included other organisations providing training in the field of law enforcement whose activities are in many cases similar, for example in terms of the subjects of training or the countries involved.Findings: The research has shown that there are several organisations in the field of law enforcement training which, although they have similarities, also have differences in terms of the subjects covered, the professions involved and the countries in which they operate. It is rather the cooperation and joint thinking between the different organisations that leads to results.Value: The value of the research lies in the customs approach, which is evident throughout the study, the gap filling nature of the article and the comparison with other organisations involved in law enforcement training.

Aim: One of the biggest challenges people face today is the development of an effective and efficient defence capability against cyber attacks. Nowadays, this is not only an expectation at the public level, but also a real need at the corporate and private user level. In this study, the author primarily wishes to draw attention to the global trends of new types of threats in the 21st century, the most vulnerable sectors, as well as to the development possibilities of the cyber security capabilities of domestic hazardous plants.Methodology: The author has conducted a qualitative research method using primary and secondary data to identify current trends and attack vectors of threats in cyberspace at global and regional levels. In addition, the author has also conducted empirical research using primary data to determine the development possibilities of the management/safety management systems of plants dealing with hazardous substances, as well as to build the resilience of the electronic information systems of these plants against cyber threats.Findings: The number of cyber-attacks have continued to grow over the last few decades, and industrial companies have become the main targets of these new types of attacks. In order for Hungary to develop an effective defence capability, especially in the case of industrial actors, it is important to create the cyber defence capability of plants dealing with hazardous materials under the supervision of the disaster management, industrial safety authority.Value: Taking stock of the possibilities of developing the security management system of domestic hazardous materials plants to protect against 21st century threats. This scientific work intends to provide more detailed information on the addition and feasibility of the management system with information security aspects.
Procedural dilemmas of cybercrimes involving illegal content dissemination in cross-border situations
Authors: Sorbán Kinga
Published: January 2024

Aim: The main purpose of this study is to provide a comprehensive overview of the procedural dimensions of the investigation of cybercrimes having an international element. In this context, it highlights the difficulties that can slow down and, in extreme cases, even prevent effective enforcement in two major areas: jurisdiction and mutual legal assistance.Methodology: As the study primarily focuses on legislative approaches, it brings together and comparatively analyses the main EU and international legal sources that regulate cooperation between countries in the field of cybercrime.Findings: Especially in the area of mutual legal assistance, the European Union is actively legislating, and the principle of indirectness, i.e., the possibility for the competent authorities to directly contact intermediary service providers established in another Member State, is increasingly gaining prominence. On one hand, this can speed up procedures, but on the other hand, it entails the risk that the numerous instruments overlap, weakening the effectiveness of enforcement.Value: As some of the legislative procedures are still underway, further research is needed to see how Member States will be able to apply the new instruments in practice.
Structuralism and Deconstruction in Biblical Scholarship: Annotated Bibliographies
Authors: Frimpong Ernest Jnr , Kuwornu-Adjaottor Jonathan Edward Tetteh
Published: January 2024

Academic referencing, though very significant in scholarship, has not been an easy task for both students and researchers, especially when one is restricted to following a particular referencing style either as instructed by one’s educational institution or by a publishing house through which one seeks a publication. In biblical scholarship, the philosophies of structuralism and deconstruction are very significant, especially as much as textual translation and interpretation are concerned. Several proponents have shared their scholarly views on how they individually appreciate these philosophical concepts. In an attempt to unravel some of such works without neglecting the authors and their central discussions, this paper employed a methodology through the construction of annotated bibliographies of such works. Findings indicated that while structuralism mainly studies the meaning of a text independently of its history and culture, deconstruction considers the world of the audience in line with the author’s intention and how that intention could be relevant to the new audience, taking into account the history of the text and the culture of the audience. Also, some of the key proponents of structuralism and its philosophical development include de Saussure, Levi-Strauss, Sasková and Titchener. Key proponents of deconstruction include Derrida, Norris, Ekem, Kuwornu-Adjaottor, Mugambi, and Nida. Significantly, with a maximum word count of 150 words and not less than 50 words, readers would understand key information contained in the sampled works of the authors through the annotations.

On the Transition from Efficient to Inefficient Line Driving in Irradiated Flows
Authors: Dannen Randall , Proga Daniel , Waters Tim , Dyda Sergei
Published: January 2024

Observations of ionized outflows from active galactic nuclei (AGNs) provide evidence of energy and momentum transfer from the AGN radiation to the plasma. The AGN radiation is very energetic. Therefore, at distances of parsec scale, where gravity is relatively weak, energy transfer alone can lead to outflow. Much closer to the black hole, gravity dominates thermal energy and the gas is in the so-called “cold” regime. Only magnetic or radiation forces can lead to outflow. However, it is unclear when the radiation force is efficient in overcoming gravity because of its dependence on the spectral energy distribution (SED) of the radiation and opacity. In this work, we survey the parameter space of radiation forces due to spectral lines resulting from blackbody SEDs with temperatures ranging from ∼104 to 106 K. The objective was to identify the radiation temperature above which line driving becomes inefficient. We find that the temperature ≲4 × 105 K marks such a transition. We also self-consistently calculate heating and cooling balance to estimate gas temperature and identify the transition where thermal driving becomes comparable to line driving. We summarize hydrodynamical simulations of radial outflows to illustrate how wind properties change during the transition from line to thermal driving and their dependence on outflow parameters and SED.

We fit the UV/optical lightcurves of the Seyfert 1 galaxy Mrk 817 to produce maps of the accretion disk temperature fluctuations δ
T resolved in time and radius. The δ
T maps are dominated by coherent radial structures that move slowly (v ≪ c) inward and outward, which conflicts with the idea that disk variability is driven only by reverberation. Instead, these slow-moving temperature fluctuations are likely due to variability intrinsic to the disk. We test how modifying the input lightcurves by smoothing and subtracting them changes the resulting δ
T maps and find that most of the temperature fluctuations exist over relatively long timescales (hundreds of days). We show how detrending active galactic nucleus (AGN) lightcurves can be used to separate the flux variations driven by the slow-moving temperature fluctuations from those driven by reverberation. We also simulate contamination of the continuum emission from the disk by continuum emission from the broad-line region (BLR), which is expected to have spectral features localized in wavelength, such as the Balmer break contaminating the U band. We find that a disk with a smooth temperature profile cannot produce a signal localized in wavelength and that any BLR contamination should appear as residuals in our model lightcurves. Given the observed residuals, we estimate that only ∼20% of the variable flux in the U and u lightcurves can be due to BLR contamination. Finally, we discus how these maps not only describe the data but can make predictions about other aspects of AGN variability.
A New Population of Mid-infrared-selected Tidal Disruption Events: Implications for Tidal Disruption Event Rates and Host Galaxy Properties

Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments; hence, we recently performed a systematic search of NEOWISE mid-IR data for nearby, obscured TDEs within roughly 200 Mpc. We identified 18 TDE candidates in galactic nuclei, using difference imaging to uncover nuclear variability among significant host galaxy emission. These candidates were selected based on the following IR light-curve properties: (1) L
W2 ≳ 1042 erg s−1 at peak; (2) fast rise, followed by a slow, monotonic decline; (3) no significant prior variability; and (4) no evidence for active galactic nucleus (AGN) activity in Wide-field Infrared Survey Explorer (WISE) colors. The majority of these sources showed no variable optical counterpart, suggesting that optical surveys indeed miss numerous obscured TDEs. Using narrow-line ionization levels and variability arguments, we identified six sources as possible underlying AGN, yielding a total of 12 TDEs in our gold sample. This gold sample yields a lower limit on the IR-selected TDE rate of (2.0 ± 0.3) × 10−5 galaxy−1 yr−1 ((1.3 ± 0.2) × 10−7 Mpc−3 yr−1), which is comparable to optical and X-ray TDE rates. The IR-selected TDE host galaxies do not show a green valley overdensity nor as a preference for quiescent, Balmer strong galaxies, which are both overrepresented in optical and X-ray TDE samples. This IR-selected sample represents a new population of dusty TDEs that have historically been missed by optical and X-ray surveys and helps alleviate tensions between observed and theoretical TDE rates and the so-called missing energy problem.
Exploiting Machine Learning and Disequilibrium in Galaxy Clusters to Obtain a Mass Profile
Authors: Henriksen Mark J. , Panda Prajwal
Published: January 2024

We use 3D k-means clustering to characterize galaxy substructure in the A2146 cluster of galaxies (z = 0.2343). This method objectively characterizes the cluster’s substructure using projected position and velocity data for 67 galaxies within a 2.305 Mpc circular region centered on the cluster's optical center. The optimal number of substructures is found to be four. Four distinct substructures with rms velocity typical of galaxy groups or low-mass subclusters, when compared to cosmological simulations of galaxy cluster formation, suggest that A2146 is in the early stages of formation. We utilize this disequilibrium, which is so prevalent in galaxy clusters at all redshifts, to construct a radial mass distribution. Substructures are bound but not virialized. This method is in contrast to previous kinematical analyses, which have assumed virialization, and ignored the ubiquitous clumping of galaxies. The best-fitting radial mass profile is much less centrally concentrated than the well-known Navarro–Frenk–White profile, indicating that the dark-matter-dominated mass distribution is flatter pre-equilibrium, becoming more centrally peaked in equilibrium through the merging of the substructure.

Dimorphos was the target of the Double Asteroid Redirection Test (DART) mission. This paper summarizes the properties of an updated shape model of Dimorphos, describes the differences between the updated shape model and an earlier version published by Daly, Ernst, Barnouin et al. (doi:10.1038/s41586-023-05810-5), summarizes the data products associated with this model, and explains where the products can be accessed. The updated shape model benefited from improved methods of incorporating limb information, which will accelerate future shape modeling efforts for other objects with limited imaging data. The updated shape model is similar to the earlier model but slightly smaller (−2.8% change in volume) than the previous Dimorphos global shape model, and the updated shape is slightly more elongated. The additional analysis reported here supports an oblate preimpact shape for Dimorphos. This result indicates that the postimpact elongation of Dimorphos derived from ground-based observations is evidence for a large crater or global reshaping of the asteroid due to the DART impact. The updated global shape model of Dimorphos, as well as the earlier version, will be available in the Planetary Data System Small Bodies Node and through the public Small Body Mapping Tool.
Research on the relationship between ESG disclosure quality and stock liquidity of Chinese listed companies
Authors: Cao Xinda , Mei Tianshen , Li Shenglan
Published: January 2024

In this article, we aim to verify the relationship between ESG disclosure quality and stock liquidity of listed companies and to provide a detailed analysis of its mechanisms. Based on the theories of information asymmetry, signal transmission, reputation, and stakeholder, we summarize and analyze the theoretical and logical framework of how ESG information disclosure can impact stock liquidity. Following the fixed effect (considering individual, year, and industry), panel model was applied to empirically test the relationship between ESG disclosure score and stock liquidity with data ranging from 2012 to 2021. The research findings indicate that improving the quality of ESG disclosure by companies can significantly enhance the level of stock liquidity. Furthermore, we analyze and verify through mechanism tests that ESG disclosure can influence stock liquidity by increasing analyst attention and media coverage (information effect) and enhancing reputation (reputation effect). From a theoretical perspective, the paper enriches the research related to the economic impact of ESG information disclosure and factors affecting stock liquidity. Also, we validate theories connected to information and reputation. From a practical perspective, the research has specific reference value for policymakers, enterprise managers, and investors.
Do not Blame Bellman: It Is Koopmans' Fault
Authors: Bloise Gaetano , Le Van Cuong , Vailakis Yiannis
Published: January 2024

We provide a unified approach to stochastic dynamic programming with recursive utility based on an elementary application of Tarski's fixed point theorem. We establish that the exclusive source of multiple values is the presence of multiple recursive utilities consistent with the given aggregator, each yielding a legitimate value of the recursive program. We also present sufficient conditions ensuring a unique value of the recursive program in some circumstances. Overall, acknowledging the unavoidable failure of uniqueness in general, we argue that the greatest fixed point of the Bellman operator should have a privileged position.
Des façades neuves aux formes anciennes : Bruxelles et le plan urbanistique « Îlot Sacré » de 1960
Authors: Scholz Dominik
Published: January 2024

Sur décision du conseil communal, la Ville de Bruxelles retrouva un aspect résolument historique à partir de 1960. De nombreux immeubles privés situés dans le centre historique se parèrent de façades en style ancien. Cette époque, connue comme destructrice envers la vieille ville, a paradoxalement mené à un renforcement de son caractère historique — un phénomène peu connu jusqu’ici. S’agit-il de l’expression particulièrement précoce d’une critique du progrès qui se manifestera ailleurs en Europe à partir des années 1970 ? Le présent article jette un nouveau regard sur l’urbanisme bruxellois. En analysant les acteurs et les discours, il s’interroge sur les raisons qui ont mené à la construction d’un nouveau centre-ville historique dans les années 1950 à 1970. L’article montre que ces raisons résident non pas dans le patriotisme local des mandataires communaux, mais dans une synergie complexe entre la politique urbanistique officielle, les protestations de la société civile et le désir d’épanouissement au niveau socio-économique.
New facades in the old style: Brussels and the “Îlot Sacré” urban plan of 1960

Promenades dans une bibliothèque : usages et représentations stendhaliens de l’objet-livre en voyage
Authors: Strèque Apolline
Published: January 2024

L’article situe l’usage stendhalien du livre relativement à l’évolution des écritures et des pratiques viatiques au tournant du xixe siècle. Dans les récits de voyage de Stendhal le livre ne constitue pas seulement une entité culturelle désincarnée mais il est avant tout envisagé dans sa matérialité, en tant qu’objet, qu’il s’agisse de ceux qu’emporte le visiteur dans ses malles, de ceux qu’il peut admirer dans les bibliothèques ou encore de celui qu’il compose à destination de futurs voyageurs. L’une des spécificités du voyage stendhalien réside donc dans la dimension concrète qu’y prend la bibliothèque et dans cet intérêt accordé au livre en tant qu’objet amené à suivre le voyageur dans ses déplacements.
Les éditions illustrées du Rouge et le Noir au xixe siècle : trois lectures de l’œuvre
Authors: Chaisemartin Amélie de
Published: January 2024

Cet article étudie les lectures du Rouge et le Noir proposées par les trois éditions illustrées de l’œuvre au xixe siècle : l’édition originale par Levavasseur en 1830, l’édition de Barba dans les « Romans populaires illustrés » en 1854 et l’édition de Conquet en 1884. L’agencement et la composition des illustrations de chacune des éditions mettent en effet en avant une interprétation différente de l’œuvre. L’article souligne les liens entre ces interprétations successives et l’évolution de la réception critique du roman au cours du siècle.
L’imaginaire violent du livre
Authors: Lammers Philipp
Published: January 2024

L’article analyse l’imaginaire du livre au sein des contributions de Stendhal à la presse anglaise et montre qu’elles sont nourries par les fantasmes anthropomorphiques et révolutionnaires. Y surgit notamment l’image d’un « livre-héros », dont la puissance est néanmoins mise en question par la commercialisation du marché du livre ainsi que par la presse de l’époque. Se tournant ensuite vers l’œuvre romanesque de Stendhal, l’article postule qu’un imaginaire du livre est présent au sein du Rouge et le Noir et que le roman intègre lui-même une réflexion métalittéraire sur son esthétique.
Fins de phrase chez Stendhal et Rossini : latence et désir
Authors: Fleury Pierre , Rault Julien
Published: January 2024

En convoquant simultanément musique et littérature, cet article souhaite interroger la phrase de Stendhal à l’aune de ce qui se joue à la clôture en termes de ponctuation, de rythme, de cadence. Que se passe-t-il entre les phrases de Stendhal du point de vue de l’achèvement et de l’accomplissement ? Comment penser la question de la latence et du désir ? Dispositif de suspension et administration du virage phrastique sont étudiés dans deux dispositifs a priori opposés, celui littéraire d’Armance (désir frustré) et celui musical de Rossini (désir récompensé), afin de sonder ce qui pourrait constituer l’un des piliers de l’imaginaire phrastique stendhalien.
Des destins croisés ?
Authors: Bertrand Gilles
Published: January 2024

L’intensité des relations entre Paris et Milan de 1800 à 1842 atteste d’une fascination réciproque. Les séjours de voyageurs aux buts variés s’ajoutent à ceux des administrateurs napoléoniens puis des patriotes du Risorgimento. Après que se fut construite à la fin du xviiie siècle une image de Milan comme « Paris de l’Italie », l’attrait de Paris perdura auprès des Milanais exilés sous les monarchies censitaires. Mais la nature intime et durable du lien entre les deux villes ne saurait se comprendre sans tenir compte du rôle de personnalités d’exception telles que Fauriel, Manzoni, Stendhal, Balzac, Clara Maffei ou Cristina di Belgiojoso.
Stendhal à l’école de Beccaria
Authors: Brumelot Tom
Published: January 2024

Cet article mesure la dette philosophique et stylistique de Stendhal envers Beccaria et les Lumi milanesi. Il se penche sur la lecture des Ricerche intorno alla natura dello stile par le jeune Beyle et ses échos. Il examine ensuite les éloges de la philosophie lombarde disséminés dans les diverses versions de Rome, Naples et Florence. En vantant le style et l’intention réformatrice de cette « haute philosophie » milanaise, Stendhal est moins partial et superficiel qu’en apparence. Enfin, le portrait par Beccaria du « style de bonhomie » est une source du ton bonhomme que se donne Stendhal et de sa construction d’une « bonhomie milanaise ».
L’ombra di Napoleone
Authors: Albergoni Gianluca
Published: January 2024

L’article se propose de creuser la question des rapports entre Stendhal et la rédaction de la revue milanaise Il Conciliatore, véritable organe du romantisme en 1818-1819. Par-delà de multiples affinités de goût en matière littéraire, c’est notamment le rapport avec l’héritage de Bonaparte qui occupe une place centrale : il se met en place une véritable tension, entre proximité et conflit, autour de la rédaction de la Vie de Napoléon et de la discussion concernant les Considérations de Mme de Staël.
Milan, l’autre patrie ?
Authors: Corredor Marie-Rose
Published: January 2024

Stendhal the “cosmopolitan” chose to call himself a Milanese: how to reconcile this cosmopolitanism inherited from the Enlightenment with the new demands of the “patriotism” born of the Revolution and Empire, and the changing geography of the mind (M. Crepon)? The importance attached to languages in general, and to the mother tongue in particular, in the European Romantic context encouraged Stendhal to be a “linguist in Milan”. But his infatuation with the Milanese language was not enough to define a sense of belonging, a “home away from home” (B. Cassin), while the French Revolution and the French language remained his reference point.
