Background and objectives. Myasthenia gravis (MG) is a chronic autoimmune disease characterized by muscle weakness. Muscle weakness leads to impairment of daily activities and leads to psychiatric symptoms, including depression. The lack of exercise methods in MG patients is a problem in rehabilitation. This study evaluates the effect of an 8-week low-intensity aerobic exercise program on Myasthenia Gravis Composite (MGC) and Beck Depression Inventory (BDI) scores in MG patients. Materials and methods. This is a randomized controlled trial conducted from May to June 2023. Twenty subjects were randomly divided into treatment group and control group. The treatment group received low-intensity aerobic exercise with cycle ergometer 3 sessions per week for 8 weeks. Both groups were informed about lifestyle changes and effective breathing exercises. MGC and BDI scores were measured and compared before and after intervention. Results. In the treatment group, MGC and BDI scores was significantly decreased with strong effect size after 8 weeks (5.4 ± 2.32 to 2.4 ± 1.84, p = 0.001, Cohen’s D = 1.57; and 10.4 ± 2.88 to 5.9 ± 2.77, p = 0.001, Cohen’s D = 1.86). In the control group, MGC and BDI scores were not significantly different (5.4 ± 2.68 to 6.0 ± 2.49, p = 0.193, Cohen’s D = 0.44; and 10.4 ± 1.71 to 9.6 ± 1.65, p = 0.247, Cohen’s D = 0.39). The MGC score strongly correlated with the BDI score (r = 0.50). Conclusion. 8 weeks of low-intensity aerobic exercise with cycling ergometer reduces disease severity and depression severity in myasthenia gravis.

Published: April 2024

There is a very bleak outlook on cyber security due to the rapid expansion of the Internet and the ever-changing terrain of cyber-attacks. This paper explores the field of intrusion detection through network analysis, with a particular emphasis on applying machine learning (ML) and deep learning (DL) approaches. For every ML/DL technique, a thorough tutorial overview is given together with a review of pertinent research publications. These studies were read, indexed, and summarised according to their thermal or temporal correlations with great care. The paper also provides information on frequently used network datasets in this field, which is relevant given the critical role that data plays in ML/DL techniques. It also discusses the difficulties in using ML/DL for cyber security and provides insightful recommendations for future lines of inquiry. Interestingly, the KDD data set shows up as a reputable industry standard for intrusion detection methods. A lot of work is being done to improve intrusion detection techniques, and both training and evaluating the detection model's quality depend equally on the quality of the data. The KDD data collection is thoroughly analysed in this research, with a special emphasis on four different attribute classes: Basic, Content, Traffic, and Host. We use the Modified Random Forest (MRF) technique to classify these properties.

Psychological research has proven that music can reduce stress, improve mood, and help release “happy” chemicals like oxytocin, serotonin, and dopamine. It's no surprise that music has always been a popular tool in clinics and in the treatment of many ailments, so as people facing mental health issues continue to wander around the world, coping with mental illness is more important than ever. Although music recommendations already exist, they do not have all the scheduling algorithms that take into account the user's needs. Considering that it is undeniable that most people listen to music on a regular basis, music has also been shown to reduce stress, pain, and blood pressure while improving cognition, memory, and sleep quality. The most comprehensive and practical product that sorts all the good music. Our goal is to improve the emotional state of the user by creating a positive feeling based on the recommended music called "Viby".

Published: April 2024

The digital revolution presents Small and Medium Enterprises with potential and danger in the dynamic world of modern business. However, several substantial obstacles are in the way of digitalization, making it difficult to move forward. This study sets out to discover and remove these hurdles to fully realize the potential of digital transformation for small and medium-sized enterprises (SMEs). It looks through the Analytical Hierarchy Process (AHP) prism. Our research identifies five types of barriers, each presenting different hurdles for digitalization: organizational, technological and infrastructure, legal, social-cultural, and strategic. We investigate several options in response, such as government regulations, technology acquisition, management support, cybersecurity, and training. Using the AHP methodology, we give each alternative a normalized value and find that management support is the most critical, closely followed by cybersecurity, government regulations, training, and technology acquisition. With these discernments, SMEs can deliberately arrange their endeavours to eliminate obstacles, clearing the path for triumphant digital transformation and sustained expansion.

Categories of Lagrangian Correspondences in Super Hilbert Spaces and Fermionic Functorial Field Theory
Authors:   Universit&, Ludewig Matthias ,   #228,   t Regensburg, Germany
Published: April 2024

In this paper, we study Lagrangian correspondences between Hilbert spaces. A main focus is the question when the composition of two Lagrangian correspondences is again Lagrangian. Our answer leads in particular to a well-defined composition law in a category of Lagrangian correspondences respecting given polarizations of the Hilbert spaces involved. As an application, we construct a functorial field theory on geometric spin manifolds with values in this category of Lagrangian correspondences, which can be viewed as a formal Wick rotation of the theory associated to a free fermionic particle in a curved spacetime.
The Relationships between Emission Geometry and Jitter Noise in Millisecond Pulsars
Authors: Yuen R.
Published: April 2024

The relationships between several parameters of an emission geometry and jitter noise in 17 millisecond pulsars (MSPs) are investigated. By assuming the jitter noise is due only to a pulse variation in phase, the former can be modeled as changes in the plasma flow rate leading to variation in the measured pulse arrival time relative to the predicted time. In the model for pulsar magnetospheres with multiple emission states, the plasma flow is associated with the emission states, and a change in the emission state corresponds to a change in the plasma flow causing variation in the pulse arrival time. These can be specified in an emission geometry defined by the obliquity and viewing angles, measured from the rotation axis to the magnetic axis and to the line of sight, respectively. We calculate the maximum change in the emission state based on the reported jitter noise for each of the MSPs. Using the results, we show that the MSPs possess relatively large obliquity angles, which is consistent with observation, and the jitter noise exhibits dependency on frequency. We find that the jitter noise in our sample displays an exponential decay as a function that combines the obliquity angle and the rotation period, revealing the correlation among the three parameters. This suggests that the magnitude of the jitter noise is likely specific to an MSP. We discuss how jitter noise may be related to the evolution of an MSP.
CGOLS V: Disk-wide Stellar Feedback and Observational Implications of the Cholla Galactic Wind Model
Authors: Schneider Evan E. , Mao S. Alwin
Published: April 2024

We present the fifth simulation in the Cholla Galactic OutfLow Simulation (CGOLS) project—a set of isolated starburst galaxy simulations modeled over large scales (10 kpc) at uniformly high resolution (Δx ≈ 5 pc). Supernova feedback in this simulation is implemented as a disk-wide distribution of clusters, and we assess the impact of this geometry on several features of the resulting outflow, including the radial profiles of various phases; mass, momentum, and energy outflow rates; covering fraction of cool gas; mock absorption-line spectra; and X-ray surface brightness. In general, we find that the outflow generated by this model is cooler, slower, and contains more mass in the cool phase than a more centrally concentrated outflow driven by a similar number of supernovae. In addition, the energy loading factors in the hot phase are an order of magnitude lower, indicating much larger losses due to radiative cooling in the outflow. However, coupling between the hot and cool phases is more efficient than in the nuclear burst case, with almost 50% of the total outflowing energy flux carried by the cool phase at a radial distance of 5 kpc. These physical differences have corresponding signatures in observable quantities: the covering fraction of cool gas is much larger, and there is greater evidence of absorption in low and intermediate ionization energy lines. Taken together, our simulations indicate that centrally concentrated starbursts are more effective at driving hot, low-density outflows that will expand far into the halo, while galaxy-wide bursts may be more effective at removing cool gas from the disk.

Investigating Protostellar Accretion is a Cycle 1 JWST program using the NIRSpec+MIRI integral field units to obtain 2.9–28 μm spectral cubes of five young protostars with luminosities of 0.2–10,000 L
⊙ in their primary accretion phase. This paper introduces the NIRSpec 2.9–5.3 μm data of the inner 840–9000 au with spatial resolutions from 28 to 300 au. The spectra show rising continuum emission; deep ice absorption; emission from H2, H i, and [Fe ii]; and the CO fundamental series in emission and absorption. Maps of the continuum emission show scattered light cavities for all five protostars. In the cavities, collimated jets are detected in [Fe ii] for the four <320 L
⊙ protostars, two of which are additionally traced in Brα. Knots of [Fe ii] emission are detected toward the most luminous protostar, and knots of [Fe ii] emission with dynamical times of <30 yr are found in the jets of the others. While only one jet is traced in H2, knots of H2 and CO are detected in the jets of four protostars. H2 is seen extending through the cavities, showing that they are filled by warm molecular gas. Bright H2 emission is seen along the walls of a single cavity, while in three cavities narrow shells of H2 emission are found, one of which has an [Fe ii] knot at its apex. These data show cavities containing collimated jets traced in atomic/ionic gas surrounded by warm molecular gas in a wide-angle wind and/or gas accelerated by bow shocks in the jets.

Published: April 2024

Sun-as-a-star spectroscopic characteristics of solar flares can be used as a benchmark for the detection and analysis of stellar flares. Here, we study the Sun-as-a-star properties of an X1.0 solar flare, using high-resolution spectroscopic data obtained by the Chinese Hα Solar Explorer (CHASE). A noise reduction algorithm based on discrete Fourier transformation is first employed to enhance the signal-to-noise ratio of the space-integral Hα spectrum, with a focus on its typical characteristics. For the flare of interest, we find that the average Hα profile displays a strong emission at the line center and an obvious line broadening. It also presents a clear red asymmetry, corresponding to a redshift velocity of around 50 km s−1 that slightly decreases with time, consistent with previous results. Furthermore, we study how the size of the space-integral region affects the characteristics of the flare's Sun-as-a-star Hα profile. It is found that although the redshift velocity calculated from the Hα profile remains unchanged, the detectability of the characteristics weakens as the space-integral region becomes larger. An upper limit on the size of the target region where the red asymmetry is detectable is estimated. It is also found that the intensity in Hα profiles, measured by the equivalent widths of the spectra, are significantly underestimated if the Hα spectra are further averaged in the time domain.
Naked Forward Shock Seen in the TeV Afterglow Data of GRB 221009A
Authors: Khangulyan Dmitry , Aharonian Felix , Taylor Andrew M.
Published: April 2024

We explore the implications of the light curve of the early TeV gamma-ray afterglow of GRB 221009A reported by the LHAASO Collaboration. We show that the reported offset of the reference time, T
*, allows the determination of the activation time of the main jet component, which occurs approximately 200 s after the Gamma-ray Burst Monitor (GBM) trigger time and closely precedes the moment at which GBM was saturated. We find that while the LHAASO data do not exclude the homogeneous circumburst medium scenario, the progenitor wind scenario looks preferable, finding excellent agreement with the expected size of the stellar bubble. We conclude that the initial growth of the light curve is dominated by processes internal to the jet or by gamma-gamma attenuation on the photons emitted during the prompt phase. Namely, either the activation of the acceleration process or the decrease of internal gamma-gamma absorption can naturally explain the initial rapid flux increase. The subsequent slow flux growth phase observed up to T
* + 18 s can be related to the process of particle accumulation in the production region. The duration of this phase allows an almost parameter-independent determination of the jet’s initial Lorentz factor, Γ0 ≈ 600, and magnetic field strength,

Stellar Black Holes Can “Stretch” Supermassive Black Hole Accretion Disks
Authors: Zhou Shuying , Sun Mouyuan , Liu Tong , Wang Jian-Min , Wang Jun-Xian , Xue Yongquan
Published: April 2024

Stellar black holes (sBHs) are widely believed to exist in the accretion disks of active galactic nuclei (AGNs). Previous studies often focus on the transient emission produced by embedded sBHs. Here, we explore the possible observational consequences of an AGN accretion disk that contains a population of accreting sBHs. Embedded accreting sBHs change the effective temperature distribution of the AGN accretion disk by heating gas in the outer regions. Two possible observational consequences are presented. First, the spectral energy distribution has a turnover feature at ∼4700 Å when the supermassive black hole mass is ∼108
M
⊙, which can help explain the observed shallow spectral shape at wavelengths >5000 Å for the Sloan Digital Sky Survey quasar composite spectrum. Second, the half-light radius of a given relatively long wavelength is significantly larger than for an AGN disk without sBHs, which can be tested by microlensing observations. With appropriate sBH distributions, the model can be reconciled with quasar microlensing disk sizes. We propose that the half-light radius–wavelength relation can be utilized to investigate the distributions of embedded sBHs in AGN accretion disks.
Generation of Low-inclination, Neptune-crossing Trans-Neptunian Objects by Planet Nine
Authors: Batygin Konstantin , Morbidelli Alessandro , Brown Michael E. , Nesvorný David
Published: April 2024

The solar system’s distant reaches exhibit a wealth of anomalous dynamical structure, hinting at the presence of a yet-undetected, massive trans-Neptunian body—Planet Nine (P9). Previous analyses have shown how orbital evolution induced by this object can explain the origins of a broad assortment of exotic orbits, ranging from those characterized by high perihelia to those with extreme inclinations. In this work, we shift the focus toward a more conventional class of TNOs and consider the observed census of long-period, nearly planar, Neptune-crossing objects as a hitherto-unexplored probe of the P9 hypothesis. To this end, we carry out comprehensive N-body simulations that self-consistently model gravitational perturbations from all giant planets, the Galactic tide, as well as passing stars, stemming from initial conditions that account for the primordial giant planet migration and Sun's early evolution within a star cluster. Accounting for observational biases, our results reveal that the orbital architecture of this group of objects aligns closely with the predictions of the P9-inclusive model. In stark contrast, the P9-free scenario is statistically rejected at a ∼5σ confidence level. Accordingly, this work introduces a new line of evidence supporting the existence of P9 and further delineates a series of observational predictions poised for near-term resolution.
UP-Home: A Self-Adaptive Solution for Smart Home Security
Authors: Silva Josival , Rosa Nelson , Aires Fernando
Published: April 2024

Smart home devices are vulnerable to attacks that put their users’ security at risk. Vulnerabilities are discovered very frequently and can expose these devices through unsecured services. Meanwhile, the lack of standardisation in upgrade methods makes smart homes a potentially vulnerable environment. Furthermore, many manufacturers release their products and then abandon them, refusing to support security updates. As a result, security updates are needed to deal with the emergence of new attacks. There are several proposals to promote security in smart homes. However, there are rare solutions where changes for security purposes occur with little or no human intervention. This paper presents UP-Home, a self-adaptive solution that manages the security of smart homes. UP-Home aims to ensure that smart home devices meet the security requirements set by industry standards. The solution can continually identify and mitigate smart home security vulnerabilities. With autonomous computing techniques, UP-Home seeks to ensure the self-protection of devices and, consequently, the entire smart home. With the UP-Home evalu-ation, it was possible to notice significant improvements in the security of the smart home without any human intervention.
Antigone versus Œdipe : l’incidence politique du désir
Authors: Assoun Paul-Laurent
Published: April 2024

Antigone et la politique : cette question touche au lien entre pouvoir et ordre symbolique. La famille incestueuse d’Œdipe est le lieu tragique d’une lignée royale. Prise dans l’âpreté du conflit intra-familial et politique, elle rappelle implacablement la Loi à laquelle elle s’offre en sacrifice. Le fameux diagnostic de Lacan sur l’héroïne de la Loi du désir s’éclaire de sa dissidence, qui montre l’aporie avec les lois de la Cité. Porte-voix féminin du symbolique, elle éclaire a contrario le politique, entre semblant et réel. Le dialogue entre Créon et Antigone campe de façon immémoriale, parce que chronique, l’aporie entre gestion et Loi, qui ramène aussi bien aux moments tragiques du politique. Désir politique versus « politique du désir ».

Cet article analyse les ressorts de ­­l’absence ­­d’engagement des locataires dans les dispositifs participatifs proposés par les bailleurs sociaux dans des quartiers ­­d’habitat social de la banlieue parisienne. Il soutient ­­l’hypothèse que les explications centrées sur les dispositions sociales individuelles sont loin ­­d’être suffisantes pour rendre compte de la ­­non-­­participation dans les grands ensembles de logements sociaux. Il propose de déplacer la focale sur les caractéristiques de ­­l’offre participative ­­elle-­­même, et révèle que la mise en marché de ­­l’intermédiation entre bailleurs et locataires, avec tout ce ­­qu’elle implique en termes de recherche ­­d’économies, de standardisation des procédures et ­­d’impersonnalisation des relations, affaiblit considérablement la mobilisation des personnes logées.
Refuser de militer : les logiques du « mésengagement » au sein du mouvement Reclaim The City au Cap (Afrique du Sud)
Authors: De Barros Margaux
Published: April 2024

Cette contribution examine la mise en retrait des activités politiques ­­d’une partie des personnes habitant un bâtiment public occupé par un mouvement social au Cap. Pour les leaders de ce mouvement, Reclaim The City (RTC), seule une occupation intense est en mesure ­­d’infléchir la position de la municipalité quant à la fin des expulsions et à la production de logements sociaux au ­­centre-­­ville. Néanmoins, en dépit de règles de vie contraignantes et ­­d’un fort contrôle social, une partie des occupants et occupantes refusent de se joindre aux activités militantes. ­­J’examine ce repli, que je qualifie de « mésengagement », qui transgresse les normes ­­d’engagement fixées par les leaders de RTC. ­­L’importance de la sphère privée, mais aussi la défiance à ­­l’égard de ces leaders et le rejet du contrôle social, sont autant de motifs qui contribuent à éloigner les occupants et occupantes des espaces de militantisme.
Le débat public ­­n’a pas eu lieu. Ressorts et effets du ­­non-­­recours à la participation des collectifs et élu·es en Toscane
Authors: O’Miel Julien
Published: April 2024

L’article porte sur la politique publique de participation de la région Toscane. Il ­­s’intéresse à ­­l’instauration ­­d’un dispositif de débat public régional sur les grands projets ­­d’infrastructures susceptible ­­d’être activé par les élu·es du territoire et certains collectifs mobilisés. Partant du constat du ­­non-­­recours à ce dispositif, ­­l’article en analyse les ressorts tant du point de vue des élu·es que des militant·es. Il cherche par ailleurs à comprendre comment les acteurs et actrices de ­­l’action publique régionale participative font du ­­non-­­recours à la politique un problème et la façon dont ­­s’impose ­­l’automaticité du débat comme solution. ­­L’article interroge plus généralement la façon dont se (re)configure ­­l’action publique participative dans un contexte de concurrence territoriale entre collectivités.

Le nombre de décès aux très grands âges a considérablement augmenté dans les deux dernières décennies. Le décompte exact de ces décès que documente la base de données internationale sur la longévité n’est établi qu’après un processus strict de validation de l’âge. Ce sont essentiellement des femmes qui atteignent ces grands âges. Les supercentenaires (110 ans ou plus) sont surreprésentés aux Antilles.
France : « Vingt ans et des cellules cancéreuses »
Authors: Méchin Nathalie
Published: April 2024

l’article présente le parcours d’une jeune femme, arrivée en thérapie sur le conseil du chirurgien qui a diagnostiqué des cellules cancéreuses. Il s’agit de mettre en lumière l’articulation entre le fonctionnement pathologique d’une famille apparemment « normale », père éducateur sportif, mère institutrice, et l’itinéraire douloureux d’une jeune femme, étudiante en réussite scolaire. Dans un premier temps l’analyse porte sur les symptômes, somatisations, conduites addictives, et les processus cliniques mis en jeu, répétitions des traumatismes, troubles narcissiques de l’identité. Dans un deuxième temps, la réflexion aborde l’oscillation entre les impasses et les solutions mises en œuvre par la patiente.

la Centrafrique a connu plus de deux décennies de conflits armés récurrents dont le dernier est le plus long et le plus dévastateur. Nous avons réalisé à Cotonou pendant 8 mois en 2017 une enquête prospective, transversale à visée descriptive et analytique pour déterminer la prévalence du trouble stress post traumatique chez les migrants centrafricains résidant dans cette ville. L’étude a consisté en un entretien clinique avec chaque sujet recruté de façon systématique selon les critères d’inclusion prédéfinis. Les données recueillies ont été colligées sur une fiche individuelle anonyme préétablie comportant les variables sociodémographiques et cliniques ainsi que le score de l’échelle d’hétéro évaluation de la dépression de HAMILTON (HAMD-21). Des 215 sujets des deux sexes inclus dans l’étude, il y avait 138 femmes et 77 hommes (sex ratio F/H = 1,79). Toutes les catégories socio professionnelles ont été concernées. Toutes les familles enquêtées étaient de type monoparental avec en moyenne 04 enfants à charge. Le voyage par avion entre Bangui et Cotonou par vol direct a été le parcours migratoire le plus utilisé (41,40 %). Les pertes et violences subies étaient les principales raisons de l’exil (40 %). Le trouble stress post traumatique a été retrouvé chez 112 sujets (81 femmes et 31 hommes), soit une prévalence de 52,09 %. Cette pathologie a été présente chez 58,70 % des femmes enquêtées et 40,26 % des hommes ( ; p=0). Parmi les facteurs associés au trouble stress post traumatique, il y avait les événements traumatisants antérieurs (conflits armés précédents), les pertes et violences subies et le sexe féminin. Les principales comorbidités psychiatriques que nous avons recensées étaient les états dépressifs majeurs chez 95 (44,10 %) ou mineurs chez 24 (11,80 %). Tous les sujets concernés par la dépression majeure avaient présenté le TSPT, soit 84,87 % des TSPT. Les symptômes obsessionnels compulsifs étaient légers chez 86 enquêtés. L’anxiété psychique avait été retrouvée chez 15 migrants, l’anxiété somatique chez 25. Il y avait 27 consommateurs d’alcool et 49 usagers d’autres substances psycho actives (cannabis & psychotropes). Aucun symptôme d’état psychotique n’avait été relevé chez les enquêtés. Nous avions entrepris une prise en charge médico-psycho-sociale pour accompagner certains de ces migrants dans la difficile situation qui était la leur.
Togo : Le traumatisme parental face au handicap mental de l’enfant, au Togo
Authors: Sogoyou Bêkeyi Iyé , Tchablé Boussanlègue , Nébié Beli Alexis
Published: April 2024

les parents, devant un enfant ne possédant pas tout l’équipement requis par la norme, se sentiront attaqués dans leurs capacités parentales et dans leur intimité en tant que parents à répondre aux besoins de l’enfant. Ils voient leurs repères affectifs et éducatifs bouleversés. Le but de cette recherche est de rechercher le lien qui existe entre le type du handicap et le traumatisme parental. Pour ce faire, nous avons utilisé la méthodologie mixte pour la collecte des données. L’enquête a été réalisée donc sur un échantillon de 101 parents d’enfants handicapés mentaux ayant inscrit leurs enfants à l’Institut Médico psycho Pédagogique (IMPP) l’ENVOL. Les parents ont été soumis au questionnaire TraumaQ. Les résultats obtenus révèlent que l’infirmité motrice cérébrale est le type de handicap qui crée un degré élevé de traumatisme et qu’il existe un lien entre le degré de traumatisme et le rand de l’enfant dans la fratrie.
Niger : Évaluation de la dépendance iatrogène à la Codéine et au Tramadol chez les drépanocytaires
Authors: Douma Maiga Djibo , Mahamane Gambo Ibrahim
Published: April 2024

l’objectif de l’étude était principalement d’évaluer avec les critères du DSMIV la dépendance à la Codéine et au Tramadol des patients suivis pour hémoglobinopathie au Centre National de Référence de la drépanocytose (CNRD) et secondairement de déterminer des facteurs de risque de dépendance. Il s’agissait d’une enquête, auprès d’un échantillon de patients suivis pour hémoglobinopathie au CNRD. Les résultats indiquaient, une prévalence de la dépendance à la Codéine et au Tramadol à 5,8 % et comme facteurs de risque : une inadéquation selon la norme de l’OMS entre la prescription d’un antalgique de palier II (Codéine ou Tramadol) et le niveau de la douleur telle que ressentie par le patient, une provenance et une dispensation non formelles de ces produits.
Côte d’Ivoire : Autonomie, soutien social au travail et stress professionnel des salariés abidjanais
Authors: Kadjo Aka , Yao René Yao , Yeo Elisabeth
Published: April 2024

cette étude vise à analyser l’effet de l’autonomie et du soutien social au travail sur le stress professionnel des salariés abidjanais. Pour ce faire, un questionnaire à été administré à un échantillon de 80 salariés d’une entreprise. Le traitement statistique des données recueillies par le « t » du student, indique d’une part que les salariés ayant une autonomie faible au travail sont plus stressés que leurs collègues qui ont une autonomie élevée. D’autre part, les salariés qui perçoivent un soutien social élevé au travail sont moins stressés que ceux ayant un soutien social faible. Ces résultats ont été interprétés à la lumière de la théorie demande-contrôle-support social de Karasek et théorell (1990).
Le rêve de la bouchère : du désir au discours
Authors: Lapinalie Bernard
Published: April 2024

À partir du rêve d’une hystérique analysante de Freud dit « le rêve de la bouchère », nous verrons que le désir inconscient est le moteur du rêve et que ça fait du rêve « la voie royale » de l’inconscient freudien. Mais nous verrons que c’est Lacan qui va donner la logique et la solution à ce que Freud a rencontré comme limite à cette voie de l’interprétation du désir qu’il a appelée « l’ombilic du rêve ». Lacan va montrer que cet ombilic est structural parce que « le désir, dans sa fonction inconsciente, est le désir de l’Autre ». Enfin nous verrons comment il pourra faire de l’hystérie un « discours » et même un modèle du lien social par la parole qu’il appellera « discours ».
Rêves… de passe

Ce texte montre que le rêve ne peut pas attester de la passe à l’analyste. Pas de rêve de passe qui puisse faire conclusion, seulement des rêves de transfert antinomiques du réveil.
Le mot « désir » et ses diverses occurrences
Authors: Gorog Jean-Jacques
Published: April 2024

Le mot « désir » est un mot de la langue et si Lacan en fait un concept il maintient tout au long les équivoques que le désir entraîne avec lui, du désir sexuel au désir de l’analyste en passant par le désir inconscient et bien d’autres. C’est ainsi qu’une grande variété de sens contribue à épaissir le mystère du désir, jusqu’au fait qu’il ne peut prendre sa valeur qu’après-coup, qu’on ne peut savoir que ce qu’était le désir quand il n’est plus.

Clinique psychanalytique : problématique éthique
Authors: Terral François
Published: April 2024

Sous ce titre « Clinique analytique : problématique éthique », et à partir d’un commentaire des dernières leçons du Séminaire VII de Lacan, L’éthique de la psychanalyse , il s’agit de montrer en quoi c’est avant tout le désir, celui de l’analyste et celui de l’analysant, qui décide de l’engagement, de l’effectuation et de l’issue d’une l’analyse. C’est aussi l’occasion d’interroger la question de l’orientation du clinicien dès lors qu’elle se réfère à la psychanalyse.
Plus jeunes donc plus verts ?
Authors: Peugny Camille
Published: April 2024

Les jeunes sont souvent décrits comme étant particulièrement sensibles aux enjeux climatiques. Cet article teste empiriquement cette hypothèse en distinguant deux dimensions des attitudes à l’égard de l’environnement : un « environnementalisme faible » qui renvoie à la prise de conscience des enjeux environnementaux, et un « environnementalisme fort » qui consiste à donner la priorité aux questions environnementales aux dépens des impératifs économiques. Dans les deux cas, le niveau de sensibilité environnementale des jeunes de moins de 30 ans ne diffère pas significativement de celui observé parmi les autres classes d’âge, même si les déterminants de cette préoccupation environnementale varient partiellement en fonction de l’âge.
