Acute small bowel obstruction (ASBO) continues to be one of the most difficult problems of emergency abdominal surgery.
Materials and methods. The results of treatment of 123 patients aged 18–80 years with ASBO were evaluated. Patients were divided into two groups: 1st - with a positive result (survivors, n = 101), 2nd — with an unfavourable result (non-survivors, n = 22).
Results. All these patients underwent emergency surgery: the adhesive disease was the main cause in 101 (82.1 %) patients with ASBO, small bowel obstruction in gallstones was in 2 (1.6 %) and volvulus was the cause in 20 (16.3 %) ) patients. Small bowel ischemia developed in 49 (39.8 %) patients: reversible in 21 (42.9 %) and irreversible in 28 (57.1 %) patients; generalized peritonitis was present in 24 (19.5 %) patients, in 18 (75 %) of them abdominal sepsis was presented according to the criteria of Sepsis-3. After the operation, 22 patients (17.9 %) died, which were analyzed: in the early stages (first 72 hours), seventeen patients (77.3 %) and others (22.7 %) - from the third to the seventh day of the postoperative period. Studies have shown that only three laboratory parameters (blood leukocytes, lactate and C-reactive protein) and one instrumental (involving the mesentery of the small intestine, free fluid in the abdomen during CT) with a probability of 80 % or more were significantly associated with strangulated ASBO, as well as six indicators with the same probability were associated with early mortality after surgery. In both groups, the main operation in 95 (77.2 %) patients was adhesiolysis, transnasal tube of the small intestine and drainage of the abdominal cavity. The choice of access for surgery (laparoscopy or laparotomy) (P = 0.000), as well as the duration of surgery (P = 0.038), affected the results of the treatment in patients under analysis, although the types of operations performed did not significantly affect the results in these groups patients (P = 1.000). Immediate results in patients depended on the development of intra-abdominal complications after surgery (P = 0.024) and the need for early re-operation (P = 0.006). The development of postoperative complications, such as cardiovascular dysfunction (P = 0.000) and respiratory dysfunction (P = 0.000), also affected the treatment outcomes in these patients.
Conclusion. It was confirmed that three laboratories and one instrumental parameter were indicated of strangulated ASBO before surgery and the six parameters studied were predictors of early mortality before surgery with a probability of 80 % or more.

An Electric-field-driven Global Coronal Magnetohydrodynamics Simulation Model Using Helioseismic and Magnetic Imager Vector-magnetic-field Synoptic Map Data
Authors: Hayashi Keiji , Wu Chin-Chun , Liou Kan 
Published: May 2022

Abstract
We present the simulation methodology and results of our new data-driven global coronal magnetohydrodynamics (MHD) simulation model. In this model, the solar-surface electric field is first calculated such that the curl will satisfy both the induction equation and the given temporal variations of the solar-surface magnetic field. We use the synoptic maps of the Helioseismic and Magnetic Imager three-component vector-magnetic-field data to specify the solar-surface magnetic-field vector for a period from Carrington Rotations (CRs) 2106 to 2110. A set of whole-Sun three-component electric-field maps are obtained for each CR transition interval of about 27.3 days. Using the inverted electric field as the driving variable, our new global coronal MHD model, with the angular resolution of π/64, can trace the evolution of the three-dimensional coronal magnetic field that matches the specified time-dependent solar-surface magnetic-field maps and simultaneously satisfies the divergence-free condition. A set of additional boundary treatments are introduced to control the contribution of the horizontal components of the magnetic field at the weak-field regions. The strength of the solar-surface magnetic field is limited to 20 Gauss for the sake of computational stability in this study. With these numerical treatments, the nonpotential coronal features, such as twisted loop structures, and their eruptive outward motions are obtained. This present model, capable of introducing three-component solar-surface magnetic-field observation data to coronal MHD simulations, is our first step toward a better model framework for the solar corona and hence solar wind.
Starduster: A Multiwavelength SED Model Based on Radiative Transfer Simulations and Deep Learning
Authors: Qiu Yisheng , Kang Xi 
Published: May 2022

Abstract
We present starduster, a supervised deep-learning model that predicts the multiwavelength spectral energy distribution (SED) from galaxy geometry parameters and star formation history by emulating dust radiative transfer simulations. The model is composed of three specifically designed neural networks, which take into account the features of dust attenuation and emission. We utilize the skirt radiative transfer simulation to produce data for the training data of neural networks. Each neural network can be trained using ∼4000–5000 samples. Compared with the direct results of the skirt simulation, our deep-learning model produces ∼0.005 mag and ∼0.1–0.2 mag errors for dust attenuation and emission, respectively. As an application, we fit our model to the observed SEDs of IC 4225 and NGC 5166. Our model can reproduce the observations and provide reasonable measurements of the inclination angle and stellar mass. However, some predicted geometry parameters are different from an image-fitting study. Our analysis implies that including a constraint at (rest-frame) ∼40 μm could alleviate the degeneracy in the parameter space for both IC 4225 and NGC 5166, leading to broadly consistent results with the image-fitting predictions. Our SED code is publicly available and can be applied to both SED fitting and SED modeling of galaxies from semianalytic models.
A Flexible Method for Estimating Luminosity Functions via Kernel Density Estimation. II. Generalization and Python Implementation

Published: May 2022

Abstract
We propose a generalization of our previous kernel density estimation (KDE) method for estimating luminosity functions (LFs). This new upgrade further extends the application scope of our KDE method, making it a very flexible approach that is suitable to deal with most bivariate LF calculation problems. From the mathematical point of view, usually the LF calculation can be abstracted as a density estimation problem in the bounded domain of

. We use the transformation-reflection KDE method (

) to solve the problem, and introduce an approximate method (

) based on one-dimensional KDE to deal with the small sample size case. In practical applications, the different versions of LF estimators can be flexibly chosen according to the Kolmogorov–Smirnov test criterion. Based on 200 simulated samples, we find that for both cases of dividing or not dividing redshift bins, especially for the latter, our method performs significantly better than the traditional binning method

. Moreover, with the increase of sample size n, our LF estimator converges to the true LF remarkably faster than

. To implement our method, we have developed a public, open-source Python toolkit, called kdeLF. With the support of kdeLF, our KDE method is expected to be a competitive alternative to existing nonparametric estimators, due to its high accuracy and excellent stability. kdeLF is available online at GitHub with further extensive documentation available.
Rhetoric of parliamentary disinformation on Twitter
Authors: Campos-Domínguez Eva , Esteve-Del-Valle Marc , Renedo-Farpón Cristina 
Published: May 2022

Democracy is based on individuals’ ability to give their opinions freely. To do this, they must have access to a multitude of reliable information sources, and this greatly depends on the characteristics of their media environments. Today, one of the main issues individuals face is the significant amount of disinformation circulating through social networks. This study focuses on parliamentary disinformation. It examines how parliamentarians contribute to generating information disorder in the digital public space. Through an exploratory content analysis ? a descriptive content analysis of 2,307 messages posted on Twitter accounts of parliamentary spokespeople and representatives of the main list of each political party in the Spanish Lower House of Parliament ? we explore disinformation rhetoric. The results allow us to conclude that, while the volume of messages shared by parliamentarians on issues susceptible to disinformation is relatively low (14% of tweets), both the themes of the tweets (COVID-19, sex-based violence, migrants or LGBTI), as well as their tone and argumentative and discursive lines, contribute to generating distrust through institutional criticism or their peers. The study deepens current knowledge of the disinformation generated by political elites, key agents of the construction of polarising narratives.
La democracia se basa en la capacidad de los individuos para generar libremente sus opiniones. Para hacerlo, necesitan tener acceso a una pluralidad de fuentes y contenidos veraces de información, y este acceso depende, en gran medida, de las características de sus entornos mediáticos. Uno de los principales problemas de la sociedad actual es el elevado volumen de desinformación que circula a través de las redes sociales. Este trabajo se centra en la desinformación parlamentaria. Observa si y cómo los parlamentarios contribuyen a generar desorden informativo en el espacio público digital. Mediante un análisis exploratorio del contenido de 2.307 mensajes publicados en Twitter por portavoces parlamentarios y representantes de la lista principal de cada grupo en el Congreso de los Diputados en España, se estudian las retóricas de desinformación. Los resultados permiten concluir que, si bien el volumen de mensajes de desinformación es relativamente bajo (14% de los tweets), tanto las temáticas (COVID-19, violencia de género, migrantes o colectivo LGTBI), como el tono y las líneas discursivas de los tweets conforman pautas que contribuyen al desorden informativo, generando desconfianza en las instituciones y entre los propios representantes parlamentarios. El estudio ahonda en el conocimiento de la desinformación generada por las élites políticas, sujetos clave en la gestación de narrativas polarizadoras.
The life of COVID-19 mask memes: A diachronic study of the pandemic memescape
Authors: Dynel Marta 
Published: May 2022

Taking as its point of departure a fine-tuned definition of an Internet meme (vis-à-vis a memetic construct), this paper reports the findings of the first diachronic study of memes, the focus being on mask memes on the vast COVID-19 mask memescape evolving in the wake of the pandemic, relative to the changing socio-political situation. The study capitalises on a diachronic corpus of user-tagged COVID-19 mask memes (posted online from January 2020 to January 2021) collected from Google through a Python script. Based on a grounded-theory approach, ten memetic categories (clustered into four groups) are extracted and examined through a multimodal discourse analytic lens. The diachronic quantitative analysis shows that the memetic constructs, inspired by the current socio-political situation/events and facilitated by the socio-political context (e.g. going into lockdown), seem to persist, albeit with varied intensity, for the best part of the year, with many individual memes going viral. Memes’ and memetic constructs’ long lifespan is indicative of users’ primary goal, which is to share interesting and/or humorous (not always newly minted or relevant) items for the sake of fun, regardless of the memes’ nature (i.e. autotelic humour for its own sake or users’ commentaries on the surrounding reality).
Tomando como punto de partida una definición precisa de un meme de Internet (frente a un constructo memético), este artículo pretende compartir los resultados obtenidos del primer estudio diacrónico sobre memes, centrado específicamente en los memes de mascarillas en el amplio panorama de memes surgido a raíz de la pandemia del COVID-19, asociado a la cambiante situación sociopolítica. El estudio utiliza un corpus diacrónico de memes con mascarillas para el COVID-19 etiquetados por usuarios (publicados en Internet desde enero de 2020 hasta enero de 2021) extraídos de Google mediante un script de Python. Sobre la base de un enfoque de teoría fundamentada, se extraen y examinan diez categorías meméticas (divididas en cuatro grupos) a través de una lente analítica de discurso multimodal. El análisis cuantitativo diacrónico muestra que los constructos meméticos, inspirados por la situación/acontecimientos sociopolíticos actuales y facilitados por el contexto sociopolítico (por ejemplo, el confinamiento), parecen persistir, aunque con intensidad variada, durante la mayor parte del año, lo que permitió que muchos memes se volvieran virales. La longevidad de los memes y los constructos meméticos es indicativa del objetivo principal de los usuarios, que es compartir elementos interesantes y/o humorísticos (no siempre nuevos o relevantes) por diversión, independientemente de la naturaleza de los memes (es decir, humor autotélico por sí mismo o comentarios de los usuarios sobre la realidad circundante).
Virtual reality with distractors to overcome public speaking anxiety in university students
Authors: Rodero Emma , Larrea Olatz 
Published: May 2022

The ability to communicate effectively is a crucial aspect of education. For college students, learning how to speak in public is essential for their academic and professional future. However, many students report fear of speaking in public, the so-called Public Speaking Anxiety (PSA). This study aims to implement a training program using Virtual Reality (VR) with distractors to reduce the college students' anxiety. Anxiety was measured with two methods: electrodermal activity and self-report. We also analyze gender differences. There were an experimental and a control group. Both groups had to deliver the same speech twice: pre-test (before training); and post-test (after the training program) while participants’ electrodermal activity was measured. Only the experimental group was trained with VR. Students also completed the Public Speaking Anxiety Scale and a survey to examine their experience. The results showed that the VR training reduced the anxiety levels significantly in the experimental group, but there were no significant differences in the control group. The data also revealed a higher level of anxiety in male than in female students. Finally, participants reported a positive impression of the VR training. These results showed the effectiveness of Virtual Reality software with distractors to reduce public speaking anxiety.
La capacidad de comunicarse de manera eficaz es un aspecto fundamental en la educación. Para los estudiantes universitarios, aprender a hablar en público es esencial para su futuro académico y profesional. Sin embargo, muchos estudiantes manifiestan tener miedo a hablar en público, lo que se conoce como ansiedad a hablar en público (PSA en inglés). Este estudio tiene como objetivo implementar un programa de capacitación utilizando Realidad Virtual (RV) con distractores para reducir la ansiedad de los estudiantes universitarios medida con actividad electrodérmica y métodos autoinformados. Para ello se utilizó un grupo experimental y otro de control. Ambos grupos tuvieron que pronunciar el mismo discurso dos veces: prueba pretest (antes del entrenamiento) y postest (después del entrenamiento) mientras se midió la actividad electrodérmica. Solo el grupo experimental fue entrenado con RV. Los estudiantes también completaron una escala de ansiedad al hablar en público y una encuesta para examinar su experiencia. Los resultados mostraron que el entrenamiento con RV redujo significativamente los niveles de ansiedad en el grupo experimental y no hubo diferencias significativas en el grupo de control. Los datos también revelaron un mayor nivel de ansiedad en los estudiantes varones que en las mujeres. Finalmente, los participantes reportaron una impresión positiva del entrenamiento con RV. Estos resultados muestran la efectividad del entrenamiento de RV con distractores para reducir la ansiedad al hablar en público.
Ce qui guide Vladimir Poutine

Published: May 2022

L’invasion de l’Ukraine par l’armée russe a été décidée par le président de la Fédération de Russie, Vladimir Poutine. Cette décision, dont on peine à voir la rationalité, invite à s’interroger sur le personnage, ce qui guide son action, sa vision du monde, ses référents idéologiques et aussi la fascination qu’il a pu exercer en dehors de la Russie. La dimension religieuse – la référence à l’orthodoxie – ne doit pas non plus être ignorée.

Les prises de position du patriarche de Moscou à propos de l’invasion de l’Ukraine ont suscité de nombreuses réactions. Il est important de déchiffrer leur imaginaire sous-jacent, qui s’appuie sur la notion de « monde russe ». On peine à voir les différences avec la position de courants religieux plus nationalistes, proches du pouvoir politique.

La perspective d’une intervention chirurgicale de réassignation de genre à l’adolescence : trancher ou pas ?
Authors: Périer Antoine , Marcelli Daniel 
Published: May 2022

La dysphorie de genre étant de plus en plus présente dans nos consultations, les demandes d’aide médicale à la réassignation de genre, hormonale et/ou chirurgicale, vont probablement croître. Si l’identité de genre, le choix d’objet sexuel, ne relèvent pas uniquement et exclusivement d’un processus physiologique prédéterminé, conserver, pour chaque être humain, sa liberté de choix impose d’en accepter la condition, à savoir le doute, si pénible et douloureux soit-il. Dans une perspective de soin, il nous apparaît important d’être attentif à la manière dont l’adolescent envisage les diverses actions à entreprendre et la possible douleur à affronter. La tension entre « souffrance psychique/douleur corporelle », source ou non d’hésitation, peut être un paradigme utile à aborder dans l’échange avec l’adolescent/te en désir de transition.
Les représentations du TDAH dans la littérature jeunesse
Authors: Savalle Isaline , Lemoine Lise , Schneider Benoît , Besançon Maud 
Published: May 2022

Le TDAH est un trouble neurodéveloppemental entraînant inattention, impulsivité et hyperactivité (APA, 2013 ; Kutuk & al., 2018), ayant des répercussions cognitives (Castellanos & Tannock, 2002 ; Sodian & al., 2003) et affectives. Les enfants concernés peuvent donc présenter des difficultés de régulation émotionnelle (Hoza, 2007) ce qui peut avoir un impact sur leur scolarisation. La littérature jeunesse permet d’aborder les représentations sur le handicap et d’ouvrir au dialogue afin de favoriser l’empathie des élèves typiques (Bland, 2013). Une analyse de contenu a été réalisée sur un corpus de 21 ouvrages jeunesse francophones sur le TDAH par la voie d’entrée des symptômes du TDAH (via le DSM-5) et de la scolarisation de l’enfant héros et nous l’avons comparé à une analyse d’un corpus anglophone. Les résultats montrent que les ouvrages abordent de façon adaptée les conséquences du TDAH pour les héros telles que leur hyperactivité et inattention, et que les histoires qui se déroulent dans le cadre scolaire mettent en scène des pairs et enseignants aux comportements clivés. Ce choix de scénario peut permettre aux enfants lecteurs de se positionner en prenant le parti des enfants moqués et en s’identifiant au groupe des défenseurs. Des différences apparaissent entre le corpus francophone et anglophone, notamment dans l’explication du trouble. Ces ouvrages présentent un intérêt certain pour sensibiliser les élèves au TDAH et ainsi favoriser le vivre ensemble.
De l’utilité d’un modèle d’‘Organisation Fondée sur le Savoir’ pour l’étude des pratiques d’exploitation du savoir
Authors: Charfi Alya 
Published: May 2022

Depuis l’émergence de la « Knowledge Based View », nombre de publications scientifiques portent sur les facteurs favorisant l’exploitation du savoir dans les entreprises. Mais peu d’entre elles traitent du design organisationnel dans sa globalité. Cet article présente un modèle d’Organisation Fondée sur le Savoir qui comprend cinq caractéristiques : management stratégique du savoir ; aplatissement de la structure verticale, processus de type projet, activité de veille et infrastructure technologique dédiée. Une étude de cas permet d’attester de l’utilité managériale du modèle pour le repérage et l’amélioration de pratiques en faveur de l’exploitation du savoir.
La dissonance cognitive des managers intermédiaires dans un contexte de lean management : quel apport du modèle des exigences-ressources ?
Authors: Aït Razouk Abdelwahab , Quemener Yann 
Published: May 2022

Afin de mieux comprendre les dispositions organisationnelles susceptibles de favoriser la réduction du coût psychologique du lean pour les managers intermédiaires (MI), nous avons associé le concept de dissonance cognitive au modèle « exigences-ressources » de Demerouti et al. (2001). Notre approche théorique est confrontée à un large échantillon de managers tiré de l’enquête REPONSE 2017. Les résultats de notre recherche montrent qu’il existe un nombre de pratiques « ressources » associées négativement à la dissonance des MI. Celles-ci permettent de modérer l’effet du lean sur l’inconfort psychologique des MI.
