Published: October 2020

Introduction: Anomalous Coronary arteries is a well-known congenital entity with variable effects. The majority of such patients are asymptomatic but some can have adverse effects like ischemia and arrhythmia. Its association with Sudden Cardiac Death in young is established.

Objective: To determine the frequency of   ACA on MDCT in patients referred for coronary artery disease assessment and to determine the origin, course, and morphological variable of SCD of ACA on MDCT.

Materials and Methods: The study was done in the Department of Cardiovascular Imaging at the Punjab Institute of Cardiology. A retrospective data of patients undergoing CTA for CAD between a  period of Jan 2009 and Dec 2017 were analyzed for the presence of  Anomalous Coronary Artery (ACA). All patients having anomalous origin from opposite coronary cusp and its course were included. The patients with myocardial bridging and coronary artery fistula were excluded.

Results: Total patients analyzed with MDCT for CAD and graft assessment between Jan 2009 and December 2017 were 8028. Fifty-three patients were excluded because of poor image quality. Among these ACA were found in 166 (2.08%). Gender distributions were 126 (75.9%) males and 40 (24.09%) females, the mean age in years was 49.31 ± 13.23. The most common ACA was Right coronary artery 83 followed by Left Circumflex 44 (26.50%), Left Anterior Descending Artery 22 (13.25%), and Left Main Stem 17 (10.24%) respectively. Fifty-three (31.92%) patients had previously unknown ACA and were found to have ACA on MDCT and 82 (49.39%) patients were referred following ICA for the confirmation of ACA. The Inter-arterial course was predominant in RCA and Left Coronary Artery 97% and 77% respectively. A retro artic course was predominant (100%) in LCx. Seven patients had associated cyanotic heart disease with ACA. Two patients(one LAD and one RCA) had origin from the Main Pulmonary artery.

Conclusion: MDCT is the imaging modality of choice for the evaluation of ACA. It can identify the origin of ACA from opposite coronary cusp and defines the malignant course of ACA for the potential risk of sudden cardiac death.
“Después del maltrato infantil… una vida continúa”. Relatos de vida acerca de los cuidadores de crianza y las experiencias de acoger a un infante maltratado
Authors: Santiago García Sara
Published: October 2020

En el presente artículo doy a conocer la experiencia de cuáles son algunas de las situaciones vivenciales por las que atravesaron los cuidadores de crianza al aceptar cuidar a un niño que se encontró en situación de abandono y maltrato, producto de la investigación cualitativa que se llevó a cabo en el año 2010 en un estudio de casos. Para iniciar con este cometido iniciaré con una pregunta, a saber ¿cómo cuidan a un niño/niña lactante maltratado algunas personas que decidieron recibirlo en su núcleo familiar, después de que éste ha sido dado de alta de una institución de salud? El acercamiento sobre este tema es poco conocido en el ámbito social y de salud en México. Es por esta relación de saberes en los contextos social, salud, psico-emocional e histórico familiar del saber de la importancia, la pertinencia y la preocupación de conocer esta realidad infantil. Hasta en años recientes la disciplina de enfermería se incorporó y formó parte del trabajo interdisciplinario y multidisciplinario de investigación en salud en situaciones de maltrato infantil e inició por cuestionar y preocuparse por este tipo de situaciones, generando algunos puntos de importancia que deben ser tratados más ampliamente sobre las formas en que las familias acogedoras brindan protección temporal del los menores maltratados.

Published: October 2020

El lavado de manos con agua y jabón es una de las maneras más efectivas y económicas para prevenir las enfermedades infecciosas, nosocomiales y mejorar la seguridad del paciente. La prevalencia de morbilidad por gastroenteritis e infecciones respiratorias en los niños son la principal causa de demanda en la consulta externa y de hospitalización; éstas enfermedades se pueden prevenir con tan solo lavarse las manos con agua y jabón. Así mismo Serguey Kolesnikov reportaron que las epidemias descendieron notablemente tras la aparición del jabón. En mayo de 2007, la Organización Mundial de la Salud publicó el documento “Nueve soluciones para la seguridad del paciente”, con el propósito de reducir los daños relacionados con la atención sanitaria que afectan a millones de pacientes en todo el mundo. Dentro de las “Nueve soluciones para la seguridad del paciente” se planteó como novena solución, mejorar la higiene de las manos para prevenir las infecciones asociadas en la atención de la salud. Por su lado, la Organización Mundial de la Salud calculó, que si médicos y enfermeras se lavaran las manos regularmente durante su jornada de trabajo, se evitarían en todo el mundo 1.4 millones de casos de infecciones adquiridas en hospitales y otros centros sanitarios por día, por lo que es necesario seguir exhortando a la población, así como al personal de salud, a conocer la técnica del lavado de manos, porque con esta labor conjunta se podría prevenir muchas enfermedades, infecciones y salvar muchas vidas.

Published: October 2020

El objeto de esta investigación fue identificar el factor de impacto de la Revista Enfermería Universitaria de la ENEO en el año 2011, como parte de la evaluación interna de la revista. Marco teórico: El factor de impacto de las revistas es el índice bibliométrico más utilizado para evaluar el número de citas que reciben en promedio y los trabajos publicados en una determinada revista. El hecho de publicar en revistas de alto factor de impacto se considera, en muchos contextos, un criterio de calidad en sí mismo, pues se asume que un artículo publicado en determinada revista es probable que reciba el mismo número de citas que el promedio de la revista. Metodología: Es un estudio bibliométrico, de corte cuantitativo, no experimental, longitudinal, retrospectivo, descriptivo y diagnóstico. La población de estudio la constituyen 47 artículos originales y de revisión, publicados en la revista en los años 2009 y 2010. Se utilizan métodos cuantitativos para estudiar la citación y métodos cualitativos para realizar el análisis del factor de impacto. La técnica de recolección de datos se realizó mediante una revisión manual de todos los artículos publicados, estandarizando el método de revisión de la revista. Resultados: En los tres años estudiados, se publicaron 13 números de la revista con 34 artículos de investigación y 13 de revisión, dando un total de 47 artículos con ocho citas entre 2009 y 2010, lo que da un factor de impacto de 0.1702 para 2011. Conclusiones: El factor de impacto de la revista ha ido en incremento, lo que implica que está siendo emisora y receptora de citas en las investigaciones publicadas al 2011. Sin embargo, es necesario incrementar el factor de impacto de la Revista Enfermería Universitaria, lo que redundará en la calidad y la importancia de los grupos de investigación que en ella publican.

Authors: Wake Tilahun B. , Amedie Wassihun Y.
Published: October 2020

The purpose of this research is to design disc cutter for cutting poly propylene random co-polymer (PPR) and high density polypropylene (HDP) extrudates. Analytical methods and software including like Catia and ANSYS are used to design the tool and analyze the effect of load on the cutter. In designing the disc Cutter, using the digital logic method of material selection, the optimum material, carbon steel 19573 with the least cost, locally obtainable, manufacturable and with hardness 63.42HRC is selected. The desired optimum combination of hardness and toughness of the cutter is obtained using hardening temperature 10200C, tempering temperature 2000C, and tempering time 120min which finally gives a hardness value of 63.42HRC. The strength and quality of cut edge are tested by cutting hard plastic PPR pipe with maximum thickness of 12.9mm. By the same setup of the cutter used in the factory the prototype disc cutter serves and its failure rate improves from cutting 150 to 250 PPR pipe pieces which was recognized by the industry. The research results can be used to design the cutter disk and fabricate a cutter with enough strength to cut different thickness of PPR pipes without breakage, reducing unwanted additional cost.

This study used a qualitative research method with a phenomenological approach to describe the values of Sufism in counseling students with risky sexual behavior. Data collection was carried out by observation, interviews, questionnaires and documentation. The results showed 1) the dynamics of students with risky sex behavior was explained by the subject's data in general, the level of religiosity was low. This is a problem faced in adolescence, namely the transition period which makes adolescent emotions less stable; 2) Sufism values in counseling are a concept of scientific counseling services that are required to be more humanistic, empirical and functional (appreciation of Islamic teachings). This counseling discusses and discusses how to build the morale of the people. Sufism counseling method begins with a futuwwah framework by applying the ascetic attitude towards the world of macrocosm and microcosm (human).

Investigating Machine Learning Approaches for Bitcoin Ransomware Payment Detection Systems
Authors: Jadhav Kirat
Published: October 2020

Cryptocurrencies have revolutionized the process of trading in the digital world. Roughly one decade since the induction of the first bitcoin block, thousands of cryptocurrencies have been introduced. The anonymity offered by the cryptocurrencies also attracted the perpetuators of cybercrime. This paper attempts to examine the different machine learning approaches for efficiently identifying ransomware payments made to the operators using bitcoin transactions. Machine learning models may be developed based on patterns differentiating such cybercrime operations from normal bitcoin transactions in order to identify and report attacks. The machine learning approaches are evaluated on bitcoin ransomware dataset. Experimental results show that Gradient Boosting and XGBoost algorithms achieved better detection rate with respect to precision, recall and F-measure rates when compared with k-Nearest Neighbor, Random Forest, Naïve Bayes and Multilayer Perceptron approaches

The nondetection of companion stars in SN Ia progenitor systems lends support to the notion of double-degenerate systems and explosions triggered by the merging of two white dwarfs. This very asymmetric process should lead to a conspicuous polarimetric signature. By contrast, observations consistently find very low continuum polarization as the signatures from the explosion process largely dominate over the pre-explosion configuration within several days. Critical information about the interaction of the ejecta with a companion and any circumstellar matter is encoded in the early polarization spectra. In this study, we obtain spectropolarimetry of SN 2018gv with the ESO Very Large Telescope at −13.6 days relative to the B-band maximum light, or ∼5 days after the estimated explosion—the earliest spectropolarimetric observations to date of any SN Ia. These early observations still show a low continuum polarization (≲0.2%) and moderate line polarization (0.30% ± 0.04% for the prominent Si ii
λ6355 feature and 0.85% ± 0.04% for the high-velocity Ca component). The high degree of spherical symmetry implied by the low-line and continuum polarization at this early epoch is consistent with explosion models of delayed detonations and is inconsistent with the merger-induced explosion scenario. The dense UV and optical photometry and optical spectroscopy within the first ∼100 days after the maximum light indicate that SN 2018gv is a normal SN Ia with similar spectrophotometric behavior to SN 2011fe.
Hyper Suprime-Cam Low Surface Brightness Galaxies. II. A Hubble Space Telescope Study of the Globular Cluster Systems of Ultradiffuse Galaxies in Groups*

Published: October 2020

We increase the sample of ultradiffuse galaxies (UDGs) in lower-density environments with characterized globular cluster (GC) populations using new Hubble Space Telescope observations of nine UDGs in group environments. While the bulk of our UDGs have GC abundances consistent with normal dwarf galaxies, two of these UDGs have excess GC populations. These two UDGs both have GC luminosity functions consistent with higher surface brightness galaxies and cluster UDGs. We then combine our nine objects with previous studies to create a catalog of UDGs with analyzed GC populations that spans a uniquely diverse range of environments. We use this catalog to examine broader trends in the GC populations of low stellar mass galaxies. The highest GC abundances are found in cluster UDGs, but whether cluster UDGs are actually more extreme requires the study of many more UDGs in groups. We find a possible positive correlation between GC abundance and stellar mass, and between GC abundance and galaxy size at fixed stellar mass. However, we see no significant relation between stellar mass and galaxy size, over our limited stellar mass range. We consider possible origins of the correlation between GC abundance and galaxy size, including the possibility that these two galaxy properties are both dependent on the galaxy dark matter halo, or that they are related through baryonic processes like internal feedback.

Published: October 2020

In the era of large surveys, yielding thousands of galaxy clusters, efficient mass proxies at all scales are necessary in order to fully utilize clusters as cosmological probes. At the cores of strong lensing clusters, the Einstein radius can be turned into a mass estimate. This efficient method has been routinely used in literature, in lieu of detailed mass models; however, its scatter, assumed to be, has not yet been quantified. Here, we assess this method by testing it against ray-traced images of cluster-scale halos from the Outer RimN-body cosmological simulation. We measure a scatter of 13.9% and a positive bias of 8.8% in, with no systematic correlation with total cluster mass, concentration, or lens or source redshifts. We find that increased deviation from spherical symmetry increases the scatter; conversely, where the lens produces arcs that cover a large fraction of its Einstein circle, both the scatter and the bias decrease. While spectroscopic redshifts of the lensed sources are critical for accurate magnifications and time delays, we show that for the purpose of estimating the total enclosed mass, the scatter introduced by source redshift uncertainty is negligible compared to other sources of error. Finally, we derive and apply an empirical correction that eliminates the bias, and reduces the scatter to 10.1% without introducing new correlations with mass, redshifts, or concentration. Our analysis provides the first quantitative assessment of the uncertainties in, and enables its effective use as a core mass estimator of strong lensing galaxy clusters.

In this paper, we report new results of spectroscopic observations of γ-ray blazar S5 0716+714 from 2019 September to 2020 March with the 2.4 m optical telescope at Lijiang Observatory of Yunnan Observatories. The median cadence of observations is ∼1 day. During the second observation period (Epoch2), the observational data reveal an extremely bright state and a bluer-when-brighter (BWB) chromatism. The BWB trend of Epoch2 differs significantly from that of the first observation period (Epoch1). A significantly brightness-dependent BWB chromatism emerges in the total data of Epoch1 and Epoch2. The BWB trend becomes weaker toward the brighter states, and likely becomes saturated at the highest state. Based on a log-parabolic function, a power law of synchrotron peak flux and frequency ν
p, and a power law of the curvature of synchrotron spectrum and its ν
p, simulation well reproduces the brightness-dependent BWB trend of S5 0716+714. The BWB trend is seemingly controlled by the shift of ν
p with respect to the observational window, and effectively may be dominated by the variations of electron average energy and magnetic field in the emitting region.
A Comprehensive Study on the Variation Phenomena of AO 0235+164
Authors: Wang Yi-Fan , Jiang Yun-Guo
Published: October 2020

The variation mechanism of blazars is a long-standing open question. Observations of polarization can provide us with more information to constrain models. In this work, we collect long-term multiwavelength data on AO 0235+164, and analyse the correlations between them by using the local cross-correlation function. We find that both γ-ray and the optical V-band light curves are correlated with the radio light curve beyond the 3σ significance level. The regions emitting the γ-ray and optical radiation coincide within errors, and are located

pc upstream of the core region of 15 GHz, which is beyond the broad-line region. The color index shows the redder-when-brighter trend in the low flux state, but turns to the bluer-when-brighter trend in the high flux state, while the γ-ray spectral index always shows the softer-when-brighter trend. We propose that such complex variation trends can be explained by the increasing jet component with two constant components. The optical polarization degree (PD) flares and optical flux flares are not synchronous. It seems that one flux peak is sandwiched by two PD peaks, which have inverse rotation trajectories in the qu plane. The helical jet model can schematically show these characteristics of polarization with fine-tuned parameters. The change in viewing angle is suggested to be the primary variable that leads to all these variations, although other possibilities such as the shock-in-jet model or the hadronic model are not excluded completely.
Systematically Measuring Ultradiffuse Galaxies in H i: Results from the Pilot Survey
Authors: Karunakaran Ananthan , Spekkens Kristine , Zaritsky Dennis , Donnerstein Richard L. , Kadowaki Jennifer , Dey Arjun
Published: October 2020

We present neutral hydrogen (H i) observations using the Robert C. Byrd Green Bank Telescope (GBT) of 70 optically detected UDG candidates in the Coma region from the Systematically Measuring Ultra-Diffuse Galaxies survey (SMUDGes). We detect H i in 18 targets, confirming nine to be gas-rich UDGs and the remainder to be foreground dwarfs. None of our H i-detected UDGs are Coma Cluster members and all but one are in low-density environments. The H i-detected UDGs are bluer and have more irregular morphologies than the redder, smoother candidates not detected in H i, with the combination of optical color and morphology being a better predictor of gas richness than either parameter alone. There is little visual difference between the gas-rich UDGs and the foreground dwarfs in the SMUDGes imaging, and distances are needed to distinguish between them. We find that the gas richnesses of our H i-confirmed UDGs and those from other samples scale with their effective radii in two stellar mass bins, possibly providing clues to their formation. We attempt to place our UDGs on the baryonic Tully–Fisher relation (BTFR) using optical ellipticities and turbulence-corrected H i line widths to estimate rotation velocities, but the potential systematics associated with fitting smooth Sérsic profiles to clumpy, low-inclination disks of low surface brightness precludes a meaningful analysis of potential BTFR offsets. These observations are a pilot for a large campaign now under way at the GBT to use the H i properties of gas-rich UDGs to quantitatively constrain how these galaxies form and evolve.
GW190814's Secondary Component with Mass 2.50–2.67 M⊙ as a Superfast Pulsar
Authors: Zhang Nai-Bo , Li Bao-An
Published: October 2020

We use Stergioulas’s RNS code for investigating fast pulsars with equations of state (EOSs) on the causality surface (where the speed of sound is equal to that of light) of the high-density EOS parameter space satisfying all known constraints from both nuclear physics and astrophysics. We show that one possible explanation for GW190814's secondary component, which has mass 2.50–2.67 M
⊙, is that it is a superfast pulsar spinning faster than 971 Hz, about 42% below its Kepler frequency. If confirmed, it would be the fastest pulsar with the highest mass yet observed. There is a large and physically allowed EOS parameter space below the causality surface where pulsars heavier than 2.50 M
⊙ are supported if they can rotate even faster with critical frequencies that depend strongly on the high-density behavior of nuclear symmetry energy.

Compressive plasma turbulence is investigated at sub-ion scales in the solar wind using both the Fast Plasma Investigation (FPI) instrument on the Magnetospheric MultiScale mission (MMS), as well as using calibrated spacecraft potential data from the Spin Plane Double Probe (SDP) instrument. The data from FPI allow the sub-ion scale region (f
sc ≳ 1 Hz) to be investigated before the instrumental noise becomes significant at a spacecraft frame frequency of f
sc ≈ 3 Hz. Whereas the calibrated spacecraft potential allows a measurement up to f
sc ≈ 40 Hz. In this work, we give a detailed description of density estimation in the solar wind using the spacecraft potential measurement from the SDP instrument on MMS. Several intervals of solar wind plasma have been processed using the methodology described and are made available. One of the intervals is investigated in more detail and the power spectral density of the compressive fluctuations is measured from the inertial range to the sub-ion range. The morphology of the density spectra can be explained by either a cascade of Alfvén waves and slow waves at large scales and kinetic Alfvén waves at sub-ion scales or more generally by the Hall effect. Using electric field measurements, the two hypotheses are discussed.

PHOEBE 2 is a Python package for modeling the observables of eclipsing star systems, but until now it has focused entirely on the forward model—that is, generating a synthetic model given fixed values of a large number of parameters describing the system and the observations. The inverse problem, obtaining orbital and stellar parameters given observational data, is more complicated and computationally expensive as it requires generating a large set of forward models to determine which set of parameters and uncertainties best represents the available observational data. The process of determining the best solution and also of obtaining reliable and robust uncertainties on those parameters often requires the use of multiple algorithms, including both optimizers and samplers. Furthermore, the forward model of PHOEBE has been designed to be as physically robust as possible, but it is computationally expensive compared to other codes. It is useful, therefore, to use whichever code is most efficient given the reasonable assumptions for a specific system, but learning the intricacies of multiple codes presents a barrier to doing this in practice. Here we present release 2.3 of PHOEBE (publicly available from http://phoebe-project.org), which introduces a general framework for defining and handling distributions on parameters and utilizing multiple different estimation, optimization, and sampling algorithms. The presented framework supports multiple forward models, including the robust model built into PHOEBE itself.

The XMM-RM project was designed to provide X-ray coverage of the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) field. Forty-one XMM-Newton exposures, placed surrounding the Chandra AEGIS field, were taken, covering an area of 6.13 deg2 and reaching a nominal exposure depth of ∼15 ks. We present an X-ray catalog of 3553 sources detected in these data, using a PSF-fitting algorithm and a sample selection threshold that produces a ∼5% fraction of spurious sources. In addition to the PSF-fitting likelihood, we calculate a second source reliability measure based on Poisson theory using source and background counts within an aperture. Using the Poissonian likelihood, we select a subsample with a high purity and find that it has number count profiles similar to previous X-ray surveys. The Bayesian method “NWAY” was employed to identify counterparts of the X-ray sources from the optical Legacy and the IR unWISE catalogs, using a two-dimensional unWISE magnitude–color prior created from optical/IR counterparts of Chandra X-ray sources. A significant number of the optical/IR counterparts correspond to sources with low detection likelihoods, proving the value of retaining the low-likelihood detections in the catalog. A total of 932 of the XMM-RM sources are covered by SDSS spectroscopic observations, where 89% of them are classified as active galactic nuclei, and 71% of these active galactic nuclei are in the SDSS-RM quasar catalog. Among the SDSS-RM quasars, 80% are detectable at the depth of the XMM observations.
Fast and Easy Access to Central European Biodiversity Data with BIOfid

Published: October 2020

The storage of data in public repositories such as the Global Biodiversity Information Facility (GBIF) or the National Center for Biotechnology Information (NCBI) is nowadays stipulated in the policies of many publishers in order to facilitate data replication or proliferation. Species occurrence records contained in legacy printed literature are no exception to this. The extent of their digital and machine-readable availability, however, is still far from matching the existing data volume (Thessen and Parr 2014). But precisely these data are becoming more and more relevant to the investigation of ongoing loss of biodiversity. In order to extract species occurrence records at a larger scale from available publications, one has to apply specialised text mining tools. However, such tools are in short supply especially for scientific literature in the German language.

The Specialised Information Service Biodiversity Research*1 BIOfid (Koch et al. 2017) aims at reducing this desideratum, inter alia, by preparing a searchable text corpus semantically enriched by a new kind of multi-label annotation. For this purpose, we feed manual annotations into automatic, machine-learning annotators. This mixture of automatic and manual methods is needed, because BIOfid approaches a new application area with respect to language (mainly German of the 19th century), text type (biological reports), and linguistic focus (technical and everyday language).

We will present current results of the performance of BIOfid’s semantic search engine and the application of independent natural language processing (NLP) tools. Most of these are freely available online, such as TextImager (Hemati et al. 2016). We will show how TextImager is tied into the BIOfid pipeline and how it is made scalable (e.g. extendible by further modules) and usable on different systems (docker containers).

Further, we will provide a short introduction to generating machine-learning training data using TextAnnotator (Abrami et al. 2019) for multi-label annotation. Annotation reproducibility can be assessed by the implementation of inter-annotator agreement methods (Abrami et al. 2020). Beyond taxon recognition and entity linking, we place particular emphasis on location and time information. For this purpose, our annotation tag-set combines general categories and biology-specific categories (including taxonomic names) with location and time ontologies. The application of the annotation categories is regimented by annotation guidelines (Lücking et al. 2020). Within the next years, our work deliverable will be a semantically accessible and data-extractable text corpus of around two million pages. In this way, BIOfid is creating a new valuable resource that expands our knowledge of biodiversity and its determinants.
What Can You Do with a TaxonWorks API?

Published: October 2020

TaxonWorks is a web-based workbench facilitating curation of a broad cross-section of biodiversity informatics concepts. Its development is currently led by the Species File Group. TaxonWorks has a large, JSON serving, application programming interface (API). This API is slowly being exposed for external use. The API is documented at https://api.taxonworks.org. Here we highlight some existing key features of the API focusing on the TaxonWorks concepts of People, Sources, Collection Objects, Taxon Names, and Downloads and provide a brief roadmap for upcoming additions. Highlights include the ability for data curators to produce shareable bibliographies, DarwinCore Archives (DwC-A), and Catalogue of Life-formatted datasets, access their nomenclature as autocompletes and via many filter facets, share Person metadata including numerous identifier types, and perform basic Geo-JSON and simple DwC-A parameter-based filtering on Collection Objects. As examples of what can be done with the API, we provide several visualizations that are straightforward to implement by those with basic R, Python, Javascript, or Ruby programming skills.
Un tourment
Authors: Chabert Catherine
Published: October 2020

L’auteur propose une réflexion théorique et clinique sur l’homosexualité à l’entrée dans l’âge adulte. À partir de la psychothérapie d’une jeune femme de vingt ans, sont explorés les destins du transfert homosexuel et de sa latéralisation en termes de choix d’objet et d’identification. Entre le complexe d’Œdipe au féminin et l’élaboration d’un deuil de l’enfance, les enjeux narcissiques et sexuels du masochisme et de la mélancolie se déploient au sein d’un processus marqué par la violence pulsionnelle et son devenir.
John D. Caputo. De la théologie comme herméneutique radicale
Authors: Gengembre Sébastien
Published: October 2020

Considérant l’œuvre théologique de John D. Caputo, Sébastien Gengembre s’enquiert de la façon dont son herméneutique inspirée de la déconstruction affecte, en particulier au regard de la croix, ce que l’on met d’ordinaire sous le nom de « Dieu ». C’est d’abord la puissance de Dieu qui se trouve mise en cause, au profit d’une force faible . C’est aussi l’être de Dieu qui s’efface au bénéfice d’un événement , de l’appel qui résonne sous le nom de Dieu. Mais c’est ce nom même qui est enfin trop fort, sans que cela empêche Caputo de faire émerger une théologie originale, dont les frontières avec la déconstruction tendent à se brouiller.
La Tradition sans l’exclusion. Richard Simon, Bossuet et le socinianisme face aux critères de l’authenticité
Authors: Tambrun Brigitte
Published: October 2020

Au xvii e  siècle, Richard Simon reproche à l’Église catholique romaine de ne pas avoir suivi, en ce qui concerne la Tradition, la règle de Vincent de Lérins qui interdit toute innovation doctrinale. En adoptant des opinions particulières à Augustin, l’Église aurait dévié de la Tradition constante des anciens Pères. Mais qui suivre lorsque deux partis opposés d’égale importance trouvent chacun des arguments dans l’Écriture et la Tradition ancienne ? Brigitte Tambrun montre que contrairement à ce que soutient Bossuet, Richard Simon n’est pas, sur les questions trinitaires, un allié des sociniens, mais qu’il tend plutôt à promouvoir une Tradition indifférenciée, sans exclusion.

La fonction du désir dans l’illusion des sosies
Authors: de Mijolla-Mellor Sophie
Published: October 2020

Les phénomènes relatifs à l’inquiétante étrangeté, au double, à l’illusion des sosies, à l’impression de déjà-vu-déjà vécu se situent à mi-chemin entre la description clinique d’un symptôme et la quête d’une modalité de pensée et de sentir qui irait au-delà du conscient. Ce texte resitue la spécificité de l’approche psychanalytique dans des phénomènes bien repérés par la neurologie, laquelle n’est pas pour autant à même de les traiter ni de comprendre pourquoi ils peuvent disparaître spontanément.
Mortifications du souffle de la voix
Authors: Christaki Angélique
Published: October 2020

Cet article porte sur l’étude du syndrome « stéréotypie » de Paul Guiraud. Les éléments cliniques du tableau de ce syndrome « Palilalie, Écholalie, Mutisme et Amimie » trouvent leur source dans la mortification concomitante du corps, du verbe et de la voix. Il s’agit d’une mortification qui peut toucher jusqu’aux réflexes moteurs du vivant et s’avérer donc, potentiellement mortelle. En rapport de ces destins mortels Paul Guiraud observe une atteinte du rythme relative aux activités mentales et corporelles chez ces patients. Au-delà de la valeur syndromale de ce tableau clinique, nous allons interroger la portée métapsychologique de cette singulière arythmie, que l’intuition clinique de ce psychiatre organiciste introduit, à propos des formes les plus sévères de la psychopathologie des psychoses et, notamment celles de l’amimie et du mutisme aphone.
Marie des Vallées (1590-1656), des hallucinations démonologiques à la mystique
Authors: Vautier Stéphane
Published: October 2020

Marie des Vallées est l’une des figures du mysticisme français du XVII e siècle. Son long parcours de plusieurs années dans les hallucinations démonologiques et l’inscription de ces troubles dans un discours mystique ont fasciné Jean Eude, le fondateur des Eudistes, qui en fit l’égérie de la nouvelle communauté. L’intérêt de ce parcours de vie est d’examiner la façon dont un trouble psychique se trouve valorisé dans une société et comment cette valorisation permet à Marie de se reconstruire.
