Actualmente las infecciones asociadas a la atención en salud representan un gran desafío en el ámbito intrahospitalario. La Organización Mundial de la Salud reconoce que es un problema de salud pública a nivel global, porque la incidencia es alta, teniendo un índice de mortalidad elevado. Se considera que millones de pacientes se ven afectados cada año por este tipo de infecciones, los costos sanitarios son directamente proporcional ya que su valor aumenta, porque los pacientes requieren antibioticoterapia, y en algunos casos será necesario el uso de soporte vital por lo que la hospitalización será prolongada.

El riesgo de adquirir infecciones dependerá del nivel de complejidad del hospital o centro médico, pero también depende de la calidad y normas de antisepsia del mismo. Se considera que en hospitales cuya complejidad sea de segundo o tercer nivel de atención, tendrán tasas altas de IAAS por las intervenciones o procedimientos que requieren los pacientes, que en muchos casos la hospitalización en dichos centros tiene una duración de varias semanas.

Cada paciente tiene características individuales, por lo que los microorganismos patógenos se comportan diferentes de acuerdo al patrón de sensibilidad del individuo o de la resistencia a los antibióticos.

La conducta del personal de salud es un factor bastante importante para contraer las infecciones adquiridas en un hospital, influyen desde medidas básicas como el lavado de manos, medidas de contención primaria, esterilización del instrumental, los equipos y en general, el ambiente hospitalario. Todos estos factores influyen en la transmisión de infecciones.
Observational Analysis and Numerical Modeling of the Solar Wind Fluctuation Spectra during Intervals of Plasma Instability
Authors: Markovskii S. A. , Vasquez Bernard J.
Published: December 2022

We perform a statistical analysis of observed magnetic spectra in the solar wind at 1 au with localized power elevations above the level of the ambient turbulent fluctuations. We show that the elevations are seen only when the intensity of the ambient fluctuations is sufficiently low. Assuming that the spectral elevations are caused by thermal-ion instabilities, this suggests that on average the effect of the solar wind background is strong enough to suppress the instability or obscure it or both. We then carry out nonlinear numerical simulations with particle ions and an electron fluid to model a thermal-ion instability coexisting with an ambient turbulence. The parameters of the simulation are taken from a known solar wind interval where an instability was assumed to exist based on the linear theory and a bi-Maxwellian fit of the observed distribution with core and secondary-beam protons. The numerical model closely matches the position of the observed spectral elevation in the wavenumber space. This confirms that the thermal-ion instability is responsible for the elevation. At the same time, the magnitude of the elevation turns out to be smaller than in the real solar wind. When higher intensity of the turbulence is used in the simulation, which is typical of solar wind in general, the power elevation is no longer seen. This is in agreement with the reduced observability of the elevations at higher intensities. However, the simulations show that the turbulence does not simply obscure the instability but also lowers its saturation level.

Published: December 2022

W51A is the most active star formation region of the giant H ii region W51. It harbors the two massive protoclusters W51e and W51 IRS2, which are very rare in the Galaxy. We aim to identify the newborn massive stars and ultracompact H ii regions to derive its distance and age. We performed Integral Field Unit observations with NIFS+ALTAIR of nine targets in the W51A subregion. The distance modulus was obtained using the spectral classification in the K band and a reddening law appropriate to the inner Galactic plane. We derived the distance and the spectral types for five of the targets, ranging from O8 to O9.5, similar to those derived from radio continuum data, except for two sources to which we assigned a somewhat later spectral type. We included another seven objects with precise spectral classification from other works, which allowed us to better constrain the distance estimate. Our spectrophotometric distance d = 4.80 ± 1.27 kpc is in good agreement with those derived from the Galactic rotation model and trigonometric parallaxes, placing the region near the tangent point of the Sagittarius arm. We conclude that the stars studied in this work have an age spread of 1.5–4 Myr, substantially older than thought to date.

Published: December 2022

Early afterglow observations of gamma-ray bursts (GRBs) are valuable for exploring the properties of their jets and ambient medium. We report our photometric and spectroscopic observations of GRB 210104A and discuss its jet properties with multiwavelength data. Our spectroscopic observation reveals several absorption features and a tentative redshift of 0.46 is identified. A bright optical flare that has a peak brightness of R = 13 mag at 112 ± 7 s was observed in the R band during 67 ∼ 165 s post the GRB trigger. The flux of the R-band afterglow decays with a slope of α
O = − 0.91 ± 0.03 at t > 650 s. The early X-ray afterglow lightcurve is a smooth bump, and it decays with a slope of α
X = −1.18 ± 0.01 at late epoch. Our joint spectral fit to the optical-X-ray afterglows during (1.1–1.3) × 104 s yields a photon index ΓO,X = −1.82 ± 0.04. The derived host galaxy extinction is A

R
= 0.87. Attributing the early optical flare to the reverse-shock (RS) emission and the late optical-X-ray emission to the forward shock emission, the optical and X-ray lightcurves at t < 3 × 104 s can be well fit adopting a Markov Chain Monte Carlo algorithm. Comparing the properties of GRB 210104A with other GRBs that have detection of bright RS emission, we show that its jet is mildly magnetized (R
B = 28), with high radiation efficiency (77%), is subenergetic (E
k,iso = 4.5 × 1051 erg), and moderately relativistic (Γ0 ∼ 35) in a density medium (n
0 ∼ 417 cm−3). It follows the tight L

γ,iso–E
p,z–Γ0 relation as with typical GRBs.
Recurrent Narrow Quasiperiodic Fast-propagating Wave Trains Excited by the Intermittent Energy Release in the Accompanying Solar Flare

Published: December 2022

About the driven mechanisms of the quasiperiodic fast-propagating (QFP) wave trains, there exist two dominant competing physical explanations: they are associated with the flaring energy release or attributed to the waveguide dispersion. Employing Solar Dynamics Observatory/Atmospheric Imaging Assembly 171 Å images, we investigated a series of QFP wave trains composed of multiple wave fronts propagating along a loop system during the accompanying flare on 2011 November 11. The wave trains showed a high correlation in start times with the energy release of the accompanying flare. Measurements show that the wave trains’ phase speed is almost consistent with its group speed with a value of about 1000 km s−1, indicating that the wave trains should not be considered dispersed waves. The period of the wave trains was the same as that of the oscillatory signal in X-ray emissions released by the flare. Thus we propose that the QFP wave trains were most likely triggered by the flare rather than by dispersion. We investigated the seismological application with the QFP waves and then obtained that the magnetic field strength of the waveguide was about 10 G. Meanwhile, we also estimated that the energy flux of the wave trains was about 1.2 × 105 erg cm−2 s−1.

We present Gemini-NIFS, Very Large Telescope-SINFONI, and Keck-OSIRIS observations of near-IR [Fe ii] emission that are associated with well-studied jets from three active T Tauri stars—RW Aur A, RY Tau, and DG Tau—taken from 2012 to 2021. We primarily cover the redshifted jet from RW Aur A and the blueshifted jets from RY Tau and DG Tau, in order to investigate long-term time variabilities that are potentially related to the activities of mass accretion and/or the stellar magnetic fields. All of these jets consist of several moving knots, with tangential velocities of 70–240 km s−1, which were ejected from the star with different velocities and at irregular time intervals. Via comparisons with the literature, we identify significant differences in the tangential velocities between 1985–2008 and 2008–2021 for the DG Tau jet. The sizes of the individual knots appear to increase with time, and, in turn, their peak brightnesses in the 1.644 μm emission decreased by up to a factor of ∼30 during the epochs of our observations. The variety of decay timescales measured in the [Fe ii] 1.644 μm emission could be attributed to different preshock conditions should the moving knots be unresolved shocks. However, our data do not exclude the possibility that these knots are due to nonuniform density/temperature distributions with another heating mechanism, or, in some cases, due to stationary shocks without proper motions. Spatially resolved observations of these knots with significantly higher angular resolutions will be necessary to better understand their physical nature.
Pulsar-candidate Selection Using a Generative Adversarial Network and ResNeXt

Published: December 2022

Pulsar research has been a hot topic in the area of astronomy since they were first discovered. Pulsar discovery is fundamental for pulsar research. While pulsars are now visible across the electromagnetic spectrum, pulsar searches with modern radio telescopes are most promising. As the performance of astronomical instruments improves, the number of pulsar candidates detected by modern radio telescopes grows at an exponential rate. The application of artificial intelligence to the field of pulsar-candidate identification can automatically and efficiently address the identification problem with enormous amounts of data. However, there are still significant challenges in enhancing the accuracy of deep-learning-based pulsar-candidate identification. These problems result primarily from the fact that real pulsar data is scarce: the number of candidates that can be successfully identified as real pulsars (positive samples) is much smaller than those candidates that turn out to not be pulsars but instead radio-frequency interference or noise (negative samples). This makes it difficult to train a machine-learning model that can accurately select those candidates that are real pulsars. Therefore a novel pulsar-candidate identification framework is proposed that combines a deep convolutional generative adversarial neural network (DCGAN) and a deep aggregation residual network (ResNeXt). To overcome sample imbalance, the DCGAN is utilized to generate images that approximate real pulsars, while observed and generated candidates are employed together to train the pulsar-candidate identification model ResNeXt. Experiments on the HTRU Medlat data set back up the framework’s performance. The precision, recall, and F1-score of the framework are 100%.
On the Injection Scale of the Turbulence in the Partially Ionized Very Local Interstellar Medium
Authors: Xu 徐 Siyao 思遥 , Li 李 Hui 晖
Published: December 2022

The cascade of magnetohydrodynamic (MHD) turbulence is subject to ion–neutral collisional damping and neutral viscous damping in the partially ionized interstellar medium. By examining the damping effects in the warm and partially ionized local interstellar medium, we find that the interstellar turbulence is damped by neutral viscosity at ∼261 au and cannot account for the turbulent magnetic fluctuations detected by Voyager 1 and 2. The MHD turbulence measured by Voyager in the very local interstellar medium (VLISM) should be locally injected in the regime where ions are decoupled from neutrals for its cascade to survive the damping effects. With the imposed ion–neutral decoupling condition and the strong turbulence condition for the observed Kolmogorov magnetic energy spectrum, we find that the turbulence in the VLISM is sub-Alfvénic, and its largest possible injection scale is ∼194 au.

Authors: Aurellia Natasha , Susilaningsih Neni , Prabowo Erik , Muniroh Muflihatul , Budiono Bernadus Parish
Published: December 2022

BACKGROUND: Chronic inflammation and excessive oxidative stress are the main mechanisms causing liver fibrosis. It releases anti-inflammatory cytokines, namely, interleukin 6 (IL-6), nitric oxide, and malondialdehyde (MDA). Curcumin acts as an anti-inflammatory, antioxidant, and antifibrotic. AIM: This study is aimed to analyze differences in IL-6 expression and MDA levels in (Deutschland, Denken, and Yoken) DDY mice with liver fibrosis after common bile duct ligation between the curcumin-treated and control groups. METHODS: This research is an experimental study with a post-test-only control group design. Seventy-five male DDY mice 20–30g were used in this study (n = 5). Mice were randomly divided into five groups, each consisting of 15 mice. The first group healthy control (HC) was the HC group given phosphate-buffered saline (PBS) solution and did not perform the CBDL. The second group negative control (NC) was a NC group given PBS solution and completed the CBDL. The third group positive control (PC) was a PC group given oral ursodeoxycholic acid (UDCA) and performed CBDL. The fourth group (P1) was assigned oral curcumin and performed the CBDL. The fifth group (P2) was given oral curcumin and UDCA and performed the CBDL. Seven, fourteen, and 21 days after ligation, liver samples were taken to examine IL-6 expression and MDA levels. RESULTS: There was a significant difference between the NC and PC groups (p = 0.00), NC and P1 (p = 0.00), NC with P2 (p = 0.00), PC with P1 (p = 0.04), PC with P2 (p = 0.04), on day 21 between the NC and PC groups (p = 0.00), NC with P1 (p = 0.00), and PC with P2 (p = 0.00). Statistical analysis of the comparison of MDA levels on days 7 and 14 found no significant difference. On day 21, there was a substantial difference between the NC group and P1 (p = 0.02). CONCLUSION: This study concluded that curcumin effectively reduced IL-6 expression and MDA levels in liver fibrosis.

Authors: Ali Ibrahim Emad Mohammed Nabiel , El-Shazli Mostafa A. , Kandeel Ahmed , Nabil Ahmed
Published: December 2022

BACKGROUND: Gastric emptying (GE) is one of the common post-operative complications after pancreaticoduodenectomy (PD). Multiple factors have been involved in this complication. Dynamic studies such as GE scintigraphy (GES) have informed us about changes in the behavior of the stomach before and after the operation.

AIM: The objective of this study is a short-term scintigraphic evaluation of GE in post-PD patients for solid food before (baseline) and after the operation for 30 days.

METHODS: Between April 2016 and September 2019, 30 patients who underwent PD were investigated for the effect on GE of solids. GE scan GES was performed for the evaluation of solids in GE on pre-operative and post-operative day 30. The operative time, blood loss, the specimens’ pathology and resection margins, the interpretation of the GES study, and finally the hospital course data were all gathered and subjected to statistical analysis.

RESULTS: Nineteen patients developed delayed GE (DGE) while four developed rapid GE or dumping. The type of pancreatic reconstruction affected the GE dynamics. DGE was evident in all cases with pancreaticogastrostomy (PG), while it was observed only in 4 patients of 15 with pancreaticojejunostomy (PJ). Seven cases developed a post-operative pancreatic fistula (POPF), 3 after PG versus 4 after PJ, and were all successfully managed conservatively.

CONCLUSION: The reconstruction method of the remnant pancreas could affect the dynamics of GE. The DGE to solids was witnessed more in cases reconstructed by PG and less in cases with PJ. Post-operative complications associated, such as POPF, are factors associated with DGE.
Perioperative Analgesic Efficiency of Ultrasound-Guided Quadratus Lumborum Block versus Epidural Analgesia in Bladder Cancer Patients Undergoing Radical Cystectomy
Authors: Bakeer Ahmed , Abdelhamid Khaled , Nabil Dina , Rawi Mohamed
Published: December 2022

Background and Aim: Multimodal analgesia is currently used for perioperative pain management after Radical cystectomy (RC). This study aimed to compare quadratus lumborum block (QLB) and thoracic epidural block (TEA) in patients subjected to RC.
Methods: This prospective randomized controlled study included 34 patients with bladder cancer subjected to RC under general anesthesia, divided into two groups. The Quadratus Group (n=17) underwent bilateral ultrasound-guided continuous QLB, and the Epidural Group (n=17) underwent continuous TEA. The primary outcome was pain intensity measured by VAS score, and the secondary outcomes were total morphine consumption during the first 48 hours after surgery, postoperative nausea score, and patient satisfaction.
Results: There were no differences between the two groups in postoperative VAS scores starting immediately after surgery up to 48 hours. Reduction of VAS score after QLB was delayed compared to that after TEA. The two groups had a comparable number of patients requesting rescue analgesia (p = 0.271) and total postoperative morphine consumption (p = 0.976) in the remaining patients. The nausea score was significantly lower in the Quadratus Group than in the Epidural Group (p = 0.020). There was no significant difference between the two groups in the satisfaction score (p=0.612). Few mild complications were detected in the two studied groups.
Conclusion: QLB and TEA are safe and effective in managing postoperative pain after radical cystectomy with similar analgesic profiles. QLB was more effective in reducing postoperative nausea and vomiting.

Published: December 2022

Background: Osteopoikilosis is a rare benign osteosclerotic dysplasia and occurs in 1/50,000 people. Osteopoikilosis is inherited in an autosomal dominant and associated with several clinical manifestations. Currently, there is no agreement on diagnosing osteopoikilosis.  In this case report, we describe a 24-year-old female patient complaining of a lump and pain in the sole of the right foot. 
Case presentation: A 24 years female complained of a painful lump on the right pedis for one year. On physical examination of the right foot found a painful lump with firm boundaries, no sign of inflammation or trauma, and 1 cm x 0,5 cm x 0,5 cm in size. We perform a radiographic examination including bone survey and found multiple homogenous sclerotic lesions were spread over almost all visualized bony structures with oval to round in shape, varied in size, and well-defined borders. The laboratory examination shows normal results. Based on the findings described above, we diagnosed the patient with osteopoikilosis. The patient was provided with analgesics as therapy and periodic observation.
Conclusion: Osteopoikilosis is a rare case and is generally found incidentally on radiographic examination. The combination of history taking, clinical manifestations, and typical radiographic findings is sufficient to establish the diagnosis. This can prevent unnecessary examinations or invasive procedures.

Early Seizures during Stroke
Authors: Naydenov Christiyan , Mancheva Velina , Manchev Lachezar , Yordanova Antoaneta
Published: December 2022

INTRODUCTION: The connections between seizures and stroke, their characteristics and features are barely developed and also very important for the outcome. The diagnostic problem leads to ineffective treatment due to difficult selection of patients who are subject to prevention with antiepileptic drugs (AEDs) on one hand. On the other hand, is impossible to exam every stroke patient by EEG. We need an algorithm for screening indicated patients and conducting the EEG. After that we can include properly AED as a prevention. Their low frequency makes them time consuming to study.
AIM: To conduct an epidemiological study of early epileptic seizures at the acute stroke phase and to derive principles for screening, diagnosis and behavior for prevention.
CONTINGENT AND DESIGN: To achieve the goal we`ve researched retrospective patients, totally amounting to 656.
RESULTS AND DISCUSSION: The factors identified so far in the genesis of seizures such as age, type and location of cerebrovascular accident and proximity to the cortex do not act alone, but in combination with undiscovered ones.
CONCLUSIONS: There are no clear criteria to outline the rules for the AED prophylactic in patients with cerebrovascular disease (CVD). The most important indicator is the systematic assessment of the risk of seizures in the course of the disease. Patients at high risk of triggering seizures and developing epilepsy in CVDs are suitable for EEG examinations with a view to timely diagnosis and treatment.
Interleukin 6, Ferritin Levels, and Glasgow Prognostic Score in Solid Cancer
Authors: Rotty Linda , Padang Mersy , Hendratta Cecilia , Haroen Harlinda , Lasut Pearla
Published: December 2022

BACKGROUND: Several pro-inflammatory cytokines have been shown to regulate cancer cell growth and contribute to cancer promotion and progression. Interleukin 6 (IL-6) regulates almost all the hallmarks of cancer such as inhibition of apoptosis, proliferation, angiogenesis, and invasiveness and is also known to regulate cell metabolism. The associated increase in serum ferritin is most likely induced by the inflammatory state. In several studies, IL-6 and ferritin have a significant role in the development and clinical outcome in solid cancer and the Glasgow Prognostic Score (GPS) is widely used as a prognostic score in solid cancer. It is currently unclear whether levels of IL-6 and ferritin correlate with GPS in solid cancer patients.

AIM: The aim of this study is to determine the correlation between IL-6 and ferritin levels with the GPS in solid cancer patients.

METHODS: This study was an analytical observational study with a cross-sectional study approach to examine the relationship between IL-6 and ferritin levels with GPS in solid cancer patients. The sampling method was carried out by consecutive sampling. The total number of samples used in the study was 32 solid cancer subjects who had just been diagnosed. IL-6 was examined by kit enzyme-linked immunosorbent assay and ferritin using immunochemiluminescent method at certified laboratory in Manado city, Indonesia. The GPS is based on the results of the patient’s C-reactive protein and albumin levels were also examined at certified laboratory in Manado city, Indonesia. Data analysis was done using SPSS version 22.

RESULTS: There were 32 patients with solid cancer who are newly diagnosed and have not undergone chemotherapy. Out of 32 patients, 17 are men (53.13%) and 15 are women (46.87%). The median age of the subject was 52.5 (33–69) years. There was a significant relationship between IL-6 levels and GPS (p = 0.011; OR 16.67 95% CI 1.617–171.783). There was no significant relationship between ferritin levels and GPS (p = 0.148; OR 5.429 95% CI 0.807–36.506). There was a statistically significant relationship between IL-6 levels and ferritin (r = 0.554; p = 0.001).

CONCLUSION: There was a significant correlation between IL-6 and GPS and there was a significant correlation between IL-6 and ferritin in solid cancer patients. IL-6 levels can be used to assess the risk of prognosis in solid cancer patients and help provide an idea of what kind of treatment will be given to patients, and can help to determine the plan treatment at the end of the life of cancer patients.

Published: December 2022

BACKGROUND: Pregnant women are one of the populations that are susceptible to coronavirus disease 2019 (COVID-19) infection due to physiological changes during pregnancy that is an adaptive response to pregnancy such as diaphragmatic elevation, increased oxygen consumption, and airway mucosal edema which can also make pregnant women more intolerant of hypoxia. In addition to being vulnerable, COVID-19 in pregnant women may have a different clinical course from the general population.

AIM: This study aims to determine the demographic and clinical characteristics in pregnancy with COVID-19 at Prof. Dr. I.G.N.G. Ngoerah Hospital, Bali, Indonesia.

METHODS: This study was a cross-sectional descriptive study using secondary data derived from patient medical records and carried out in the delivery room and medical record installation at Prof. Dr. I.G.N.G. Ngoerah Hospital, Bali, Indonesia, for the period of April 1, 2020–March 31, 2021.

RESULTS: Of the 275 patients, most were in the age range of 26–30 years (46.55%), in the third trimester (81.45%), and patients came alone (54.18%). Most of the patients came without symptoms with reactive rapid antibody results (60.97%). Of the 197 patients who delivered, 84.77% had CS and 66.55% without oxygen therapy. About 69.69% of patients experienced complications and the mortality rate was 1.09%. The highest birth weight was >2500 g by 76.8%, with the good neonatal outcome (82.92%) and negative swab results (89.45%). Inflammatory markers tend to increase as symptoms increase. Neutrophil-to-lymphocyte ratio, procalcitonin, and ferritin were markedly increased from moderate symptoms to severe-critical symptoms. The same was true for ferritin levels, where there was a sharp rise in significant symptoms. Meanwhile, procalcitonin levels have started to increase quite strikingly from moderate symptoms to the highest in severe symptoms.

CONCLUSION: It is hoped that this demographic and clinical picture would further our understanding of COVID-19 and help us develop methods to lessen the disease’s severity and spread to enhance maternal and newborn outcomes.

Authors: Kareem Rafiq Salih , Baram Aram
Published: December 2022

Background: Bronchoscopy is an invasive procedure that has been used for a long time for diagnostic and therapeutic purposes. Objective: To assess the degree of satisfaction, duration, and level of cooperativeness among patients undergoing flexible fiberoptic bronchoscopy. Methods: The A quasi-experimental study was carried out on 128 flexible bronchoscopy patients that were equally divided into control and study groups. The program was applied only to the study group, and all procedure steps were discussed with patients by video records. The anxiety level score, patient satisfaction, and duration of the procedure were assessed in both groups. Results: The highest age range of patients was 61-90 years, with 38 patients from the study group (59.4%) and 44 from the control group (68.8%). Also, in both groups, most patients were illiterate, non-smokers, from nonduty areas, not city center residents, and had more than one associated comorbidity. The hospital anxiety scale was highly significant in the study group (p=0.0001), and the patient's satisfaction rate in the same group was significant (p=0.001). The procedure duration was significantly shorter in the study group (1.381 minutes) than in the control group. Conclusions: Patients with a better knowledge of the bronchoscopy procedure were more comfortable with the process, and the procedure duration was significantly shorter. Moreover, the process results in minimizing the levels of anxiety and improving the tolerability of the patients.

Published: December 2022

A new species,Diplostephium paposanumS.T.Ibáñez & Muñoz-Schick,sp. nov., is described for Chile, extending the southern distribution of the genus. Its position within the genus was confirmed by morphological and molecular data, discussed here. The new species was found in a coastal environment, new to the genus, and is geographically far removed from the other Chilean species, which are from the Andes. The formation where it occurs, known as lomas, acts as a biodiversity refuge in hyperarid environments. The presence ofD. paposanumin this environment contributes to the evidence of a floristic connection between the Atacama Desert and the Neotropical Andes.

Monika Grütters, une politique de la mémoire
Authors: Vernerey-Laplace Denise
Published: December 2022

L’engagement politique de Monika Grütters (Münster, 1962) accompagne l’histoire allemande des restitutions d’œuvres spoliées aux familles juives sous le régime nazi. Membre de la CDU, proche de Angela Merkel – l’une catholique, l’autre protestante –, vice-présidente de la Commission Culture et Média de 2009 à 2013, elle est déléguée fédérale à la culture et aux médias jusqu’en 2021. C’est grâce à l’engagement de Monika Grütters que l’Allemagne a écrit sa « politique de la mémoire » dans les faits. Certes, depuis le départ des Alliés, le pays s’est doté de structures juridiques (Loi Brüg, 1957) et administratives (Treuhandverwaltung für Kulturgut, TVK, 1952-1962). Mais, dans les faits, elles n’ont eu qu’une portée limitée ; à la fermeture de la TVK en 1962, 20 000 œuvres sont encore « orphelines ». La politique de restitution ne s’affirme réellement en Allemagne qu’à partir de 1990. Après les accords de Washington en 1998, l’activité de la Commission Limbach se cantonne encore à une pure médiation. Mais, lors de l’Affaire Gurlitt en 2010, la ministre procède à quelques restitutions retentissantes, celle du Portrait de Thomas Couture, entre autres. En 2020, elle prend parti et restitue trois tableaux aux ayants-droits de l’avocat juif Armand-Isaac Dorville. Dès 2013, elle inscrit cette même volonté à l’égard des demandes de restitution d’œuvres illicitement acquises dans un contexte colonial. En Europe, l’Allemagne a été pionnière dans la restitution des bronzes du Bénin.
La vie, la mort — la variété
Authors: Cheval Olivier
Published: December 2022

Nous avons découvert Olivier Cheval dans les pages de Lundi Matin , où il a écrit sur le chemsex et le pass sanitaire, et de l’excellente revue de cinéma Débordements , où ses réflexions sur la cinéphilie sont tressées d’anecdotes personnelles et de scènes d’amitié. Nous nous sommes dit que ce jeune homme avait du talent et que décidemment les personnes qui s’intéressent au cinéma étaient souvent plus à l’aise pour écrire en partant de leurs vies. À notre invitation ouverte, il a répondu avec un texte qui met le doigt sur des épiphanies sentimentales et confuses, qui apparaissent d’abord comme ses histoires à lui, mais qui ont aussi été les nôtres à l’écoute des mêmes chansons de variet’ — un répertoire qu’il nous fallait bien aborder tôt ou tard dans ces pages, au-delà du seul cas de Céline Dion (voir Audimat 3). Il y a dans ce texte toute la magie de l’exercice de l’essai, qui rend soudain évidente et partageable une expérience qui paraissait jusqu’alors irrémédiablement nébuleuse et subjective.
Stock Price Crash Risk, Managerial Ownership, and Cost of Debt
Authors: Depoers Florence , Guizani Assil , Lakhal Faten
Published: December 2022

L’objectif de cet article est d’étudier l’effet du risque de chute du cours d’action sur le coût d’endettement des sociétés françaises cotées. Sur un échantillon de 221 entreprises, nous constatons que les chutes de cours augmentent le coût d’endettement, ce qui suggère que les créanciers considèrent ces chutes comme un facteur important du risque de crédit. Cet effet est plus prononcé en présence d’un risque systématique élevé et en présence d’une forte asymétrie d’information. Nous montrons également que l’effet des chutes du cours sur le coût de l’endettement est plus faible dans les entreprises dirigées par leur propriétaire et dans les entreprises familiales. Ces résultats sont conformes à la thèse de l’alignement des intérêts entre les dirigeants et les créanciers. En outre, la relation personnelle que les dirigeants-propriétaires et la famille propriétaire peuvent établir avec les créanciers à travers leurs réseaux sociaux peut aider l’entreprise à obtenir des ressources financières à moindre coût.
L’année 1521 en chansons
Authors: Vissière Laurent
Published: December 2022

Les soldats français au début du xvi e  siècle chantaient beaucoup, mais leurs chants, qui se sont mal conservés, n’ont guère suscité l’intérêt des chercheurs. On conserve cependant pour l’année 1521 un corpus documentaire cohérent d’une douzaine de chansons, dont six sur le seul siège de Mézières et trois sur celui d’Hesdin. Chantés « sur l’air de », ces textes offrent un extraordinaire aperçu de la vie quotidienne et du ressenti des soldats en campagne, mais aussi d’une culture populaire toujours difficile à appréhender.
Polyphonie et théâtralité à travers les deux chansons de Guyard parues chez Attaingnant en 1534
Authors: Duchamp Jean
Published: December 2022

Nombreux sont les compositeurs de la Renaissance n’ayant laissé pour toute trace que quelques chansons. C’est le cas de Guiard dont cet article présente les deux chansons éditées chez Attaingnant en 1534. Toutes deux sont singulièrement dialoguées. L’une est une chanson à danser perpétuant un thème ancestral dans une mise en polyphonie qui annonce le style « voix de ville ». L’autre est un tableau descriptif narrant les retrouvailles et le banquet d’une joyeuse équipe de musiciens. La scène, entièrement dialoguée repose sur un centon liturgique citant des introïts finement agencés en fonction de l’action. Ces deux pièces, aussi allègres que singulières marquent donc la proximité de la chanson française avec le théâtre profane
L’art du chant de Jacques Mauduit : l’apport du témoignage de Marin Mersenne
Authors: Gominet-Brun Julien
Published: December 2022

Le musicien Jacques Mauduit participa à l’Académie de Baïf et composa des pièces inspirées par les théories du vers mesuré. Beaucoup de partitions sont perdues, d’autres ont été conservées dans les traités de Marin Mersenne. Cet article retrace l’apport du témoignage de Mersenne sur l’art de Mauduit : ses œuvres et leur esthétique, le dialogue entre le chant et la poésie.
Improved salp swarm algorithm based on gravitational search and multi-leader search strategies
Authors: Zhang Xuncai , Liu Guanhe , Zhao Kai , Niu Ying
Published: December 2022

The salp swarm algorithm (SSA) will converge prematurely and fall into local optimum when solving complex high-dimensional multimodal optimization tasks. This paper proposes an improved SSA (GMLSSA) based on gravitational search and multi-swarm search strategies. In the gravitational search strategy, using multiple salp individuals to guide the location update of search agents can get rid of the limitation of individual guidance and improve the exploration ability of the algorithm. In the multi-swarm leader strategy, the original population is divided into several independent subgroups to increase population diversity and avoid falling into local optimization. In the experiment, 20 benchmark functions (including the well-known CEC 2014 function) were used to test the performance of the proposed GMLSSA in different dimensions, and the results were compared with the most advanced search algorithm and SSA variants. The experimental results are evaluated through four different analysis methods: numerical, stability, high-dimensional performance, and statistics. These results conclude that GMLSSA has better solution quality, convergence accuracy, and stability. In addition, GMLSSA is used to solve the tension/compression spring design problem (TCSD). The proposed GMLSSA is superior to other competitors in terms of solution quality, convergence accuracy, and stability.
Banquetes, reputación y obligación social en el Egipto romano: notas sobre las invitaciones a fiestas en los papiros
Authors: De Frutos García Alba
Published: December 2022

El objetivo de este trabajo es analizar el corpus de invitaciones a fiestas en papiro dentro del contexto de las dinámicas sociales de la comensalía en el Egipto romano. A partir del concepto de «hospitalidad comensal» acuñado por Dietler, este trabajo explora el papel desempeñado por los diferentes miembros de las comunidades de comensales en los banquetes, así como las implicaciones de invitar y ser invitado a una fiesta. El objetivo último del trabajo es tratar de determinar en qué medida la celebración de fiestas, la circulación de las correspondientes invitaciones y la participación en dichas fiestas pueden ponerse en relación con un intento por parte de anfitriones e invitados de obtener y acumular prestigio y reputación dentro del grupo.
Nihil addo, ducas licet. La addictio del iudicatus en una atelana de Novio (fr. 115 Ribbeck3 = 110 Frassinetti)
Authors: Hernández Pérez Ricardo , Valiño Arcos Alejandro
Published: December 2022

El fragmento atelánico en cuestión, cuyo contexto es la representación escénica de la addictio de un deudor insolvente a su acreedor conforme a la legis actio per manus iniectionem, es analizado en relación con otras fuentes de significación jurídica que atestiguan la supervivencia de este procedimiento de ejecución personal en el s. I a. C., así como con otros pasajes de la comedia latina —pertenecientes al propio Novio y a Plauto— en los que dicha situación jurídica es utilizada como recurso cómico. La frase nihil addo es intencionadamente ambigua porque puede entenderse como «no digo nada más» pero también como «no pago una suma mayor», bien porque el personaje que la pronuncia haya supuesto equivocadamente que se trata de una subasta con pacto de in diem addictio, bien porque no esté dispuesto a intervenir como uindex del deudor para sustraerlo de la addictio.

Using Support Networks as a Predictor of Success for STEM Degrees: Preliminary Results Detailing a Selection Process for Test Subjects Engaged in a Longitudinal Study of Low Socio-Economic Status American Undergraduate Students

This study follows the selection process for participants in a National Science Foundation S-STEM grant program for low socio-economic students. State land grant institution were created to provide states with technical universities for mid- to lower-class citizens, but they have generally failed to deliver successful instruction to residential, low-socioeconomic status, underrepresented minority students. There is a need for more research on additional predictors to assess the potential of non-traditional students in the admissions process. The primary research question in this work is whether students from low-SES backgrounds possessing lower incoming metrics can still have success earning a STEM degree with the help of a web of support adults. This metrics-based selection process was generated from a five-year study of underrepresented minority (URM) students who had previously succeeded in earning an engineering degree, even though they were not originally admitted into engineering. The selection process also asked students to identify the members of their support network, how they used this support to succeed in life, and culminated in an on-campus interview. The high school metrics for these students were found to be significantly lower than their engineering peers, but the average number of anchor/mentors that were identified was 6.2. These 21 students are currently performing well and will be compared against other residential students for retention, performance, and graduation through their time at the institution.
Tobias Stimmer : scènes de meurtre, de combat et de bataille illustrant le Flavius Josèphe paru chez Theodosius Rihel à Strasbourg en 1574
Authors: Kintz Pierre
Published: December 2022

L’invention de l’imprimerie et le développement de la Réforme au XVIe siècle ont permis la multiplication des versions de la Bible, souvent agrémentées d’illustrations sous formes de gravures insérées dans le texte. Ces « Figures de la Bible » connaissent un succès croissant et ont permis à des artistes du monde rhénan d’acquérir une notoriété, dans la lignée d’Albrecht Dürer. À Strasbourg, Tobias Stimmer (1539-1584) a illustré une version allemande des Antiquités Judaïques et de la Guerre des Juifs contre Rome de Flavius Josèphe, historien romain d’origine juive (14 éditions ont paru chez Theodosius Rihel à Bâle à partir de 1574). Il a réalisé les illustrations d’un recueil de scènes bibliques (Neue künstliche Figuren Biblischer Historien en 1576). Les éditions de ces textes étaient très en vogue dans les cours européennes et dans les familles bourgeoises.Le thème des scènes de meurtre, combat et bataille est récurrent dans les illustrations de l’histoire biblique. Ces épisodes sont ainsi répartis dans la version du Flavius Josèphe illustrée par Stimmer et décrites dans l’article : scènes de meurtre (4 illustrations), scènes de combat (2 illustrations), scènes de batailles (10 illustrations) dans l’édition de 1603 de la BNUS.Tobias Stimmer s’inscrit dans les courants religieux et culturels de son époque, considéré comme un représentant particulièrement significatif d’un maniérisme du Rhin supérieur.
Une visite royale : la dernière dauphine, Marie-Thérèse Charlotte de France à Strasbourg (14-16 septembre 1828)
Authors: Mensch Matthieu
Published: December 2022

Lors du retour au pouvoir de la dynastie des Bourbons, en 1814, il lui semble important de repartir à la conquête symbolique de son royaume. L’ensemble des membres de la famille royale est mobilisé et sillonne les routes de France.L’Alsace n’est pourtant pas visitée avant 1828 mais elle est doublement honorée. Un premier voyage dans toute la province est organisé pour le roi Charles X et son fils, le dauphin Louis-Antoine, puis un second, pour la dauphine Marie-Thérèse Charlotte. Fille de Louis XVI, rescapée du Temple, la princesse, bien qu’âgée de cinquante ans, continue de susciter la compassion et reste un des membres les mieux connus de la famille royale. Pour la première fois, Strasbourg accueille une princesse Bourbon de naissance, future reine de France, en voyage officiel. Cette cérémonie importante du rituel monarchique médiéval et moderne est ici repensée et adaptée pour des objectifs politiques nouveaux au service de la monarchie restaurée.La dauphine, comme agent de la propagande royaliste, cherche à gagner une région peu encline aux Bourbons, en proposant une visite plus sensible, complément nécessaire à celle plus virile des Princes.
