Abstract
We present stellar rotation rates derived from Transiting Exoplanet Survey Satellite (TESS) light curves for stars in Upper Centaurus–Lupus (UCL; ∼136 pc, ∼16 Myr) and Lower Centaurus–Crux (LCC; ∼115 pc, ∼17 Myr). We find spot-modulated periods (P) for ∼90% of members. The range of light-curve and periodogram shapes echoes that found for other clusters with K2, but fewer multiperiod stars may be an indication of the different noise characteristics of TESS, or a result of the source selection methods here. The distribution of P as a function of color as a proxy for mass fits nicely in between that for both older and younger clusters observed by K2, with fast rotators being found among both the highest and lowest masses probed here, and a well-organized distribution of M-star rotation rates. About 13% of the stars have an infrared excess, suggesting a circumstellar disk; this is well matched to expectations, given the age of the stars. There is an obvious pileup of disked M stars at P ∼ 2 days, and the pileup may move to shorter P as the mass decreases. There is also a strong concentration of disk-free M stars at P ∼ 2 days, hinting that perhaps these stars have recently freed themselves from their disks. Exploring the rotation rates of stars in UCL/LCC has the potential to help us understand the beginning of the end of the influence of disks on rotation, and the timescale on which stars respond to unlocking.

Abstract
The radio galaxy M87 is the central dominant galaxy of the Virgo Cluster. Very high-energy (VHE, ≳0.1 TeV) emission from M87 has been detected by imaging air Cherenkov telescopes. Recently, marginal evidence for VHE long-term emission has also been observed by the High Altitude Water Cherenkov Observatory, a gamma-ray and cosmic-ray detector array located in Puebla, Mexico. The mechanism that produces VHE emission in M87 remains unclear. This emission originates in its prominent jet, which has been spatially resolved from radio to X-rays. In this paper, we construct a spectral energy distribution from radio to gamma rays that is representative of the nonflaring activity of the source, and in order to explain the observed emission, we fit it with a lepto-hadronic emission model. We found that this model is able to explain nonflaring VHE emission of M87 as well as an orphan flare reported in 2005.

Abstract
Parker Solar Probe (PSP) has shown that the solar wind in the inner heliosphere is characterized by the quasi omnipresence of magnetic switchbacks (“switchback” hereinafter), local backward bends of magnetic field lines. Switchbacks also tend to come in patches, with a large-scale modulation that appears to have a spatial scale size comparable to supergranulation on the Sun. Here we inspect data from the first 10 encounters of PSP focusing on different time intervals when clear switchback patches were observed by PSP. We show that the switchbacks modulation, on a timescale of several hours, seems to be independent of whether PSP is near perihelion, when it rapidly traverses large swaths of longitude remaining at the same heliocentric distance, or near the radial-scan part of its orbit, when PSP hovers over the same longitude on the Sun while rapidly moving radially inwards or outwards. This implies that switchback patches must also have an intrinsically temporal modulation most probably originating at the Sun. Between two consecutive patches, the magnetic field is usually very quiescent with weak fluctuations. We compare various parameters between the quiescent intervals and the switchback intervals. The results show that the quiescent intervals are typically less Alfvénic than switchback intervals, and the magnetic power spectrum is usually shallower in quiescent intervals. We propose that the temporal modulation of switchback patches may be related to the “breathing” of emerging flux that appears in images as the formation of “bubbles” below prominences in the Hinode/SOT observations.
Le poste de la guerre d’Indochine : l’échec de la pacification
Authors: Cadeau Ivan 
Published: August 2022

La guerre d’Indochine est marquée de représentations quelque peu faussées. Dans ces dernières, la place occupée par les troupes d’élite – légionnaires et parachutistes, principalement – apparaît prépondérante, tout comme les opérations auxquelles elles ont participé, la bataille de Diên Biên Phu en premier lieu. Pourtant, ces grands engagements restent relativement rares et il est possible d’affirmer que la guerre d’Indochine a d’abord été une guerre de postes. Utilisé de manière générique, le mot « poste » renvoie cependant à des réalités bien différentes. Rien de commun, en effet, entre la tour de garde et le poste accueillant une garnison d’une centaine d’hommes, ou entre le « poste kilométrique » et le blockhaus de la ligne de Lattre. Pourtant, chacune de ces fortifications participe de la politique de pacification mise en place par le commandement français. Celle-ci, contrairement à la pacification pratiquée au temps de la période coloniale (par les généraux Gallieni et Pennequin) s’avère un échec. Du fait de la prise en main et de l’encadrement idéologique des populations par le Viêt-Minh, celles-ci échappent progressivement à l’influence des Français.
De la pacification à la contre-insurrection, la recherche d’une méthode : Cambodge, 1946-1953
Authors: Maloux Thierry 
Published: August 2022

Cet article propose une réflexion sur les méthodes de « pacification » utilisées sur le théâtre cambodgien pendant la guerre d’Indochine. Il s’inscrit dans le champ des études menées sur la guerre « au milieu des populations », en examinant la singularité des approches khmère, vietnamienne et française. Il décrit la succession des expériences entreprises pour contrôler les populations en se concentrant sur la méthode du regroupement, de l’organisation de l’auto-défense et de l’action de propagande. Il tente de démontrer l’importance de la complémentarité des facteurs politiques et militaires et ses conséquences en termes d’action psychologique. Ainsi, les expériences du théâtre cambodgien inspireront les principes de la doctrine française de guerre contre-insurrectionnelle.
1952 : une lueur d’espoir sur le front de la pacification en Indochine
Authors: Le Page Jean-Marc 
Published: August 2022

En 1952 le corps expéditionnaire français en Extrême-Orient se trouve dans une impasse. Le Nord-Vietnam subit les coups des éléments vietminh infiltrés dans le Delta. La politique de pacification mise en œuvre jusque-là ne permet pas aux Franco-Vietnamiens de reprendre la main. Dans ce contexte le général de Linarès, commandant les troupes du Tonkin, met en œuvre un nouveau plan de pacification qui conjugue des opérations militaires à une action administrative et politique menée par les autorités vietnamiennes. Les innovations sont nombreuses ; GAMO, milices, bataillons légers… En même temps les forces françaises mettent en place un bureau de guerre psychologique et des organismes de liaisons avec les autorités vietnamiennes. Elles entament un nouveau cycle dans lequel la France n’est plus au centre du jeu politique mais laisse la place au gouvernement vietnamien.
Le même nous . Identité et réminiscence chez Condillac
Authors: Frigo Alberto 
Published: August 2022

Dans l’ Essai sur l’origine des connaissances humaines , Condillac propose une doctrine de la réminiscence fort originale, mais qui n’est pas dépourvue de difficultés. Pour rendre raison de ces difficultés, il convient de revenir sur les sources des thèses de Condillac, et notamment sur ses sources cartésiennes, qui doublent l’influence bien connue de l’ Essay de Locke. On verra ainsi que l’analyse condillacienne de la réminiscence constitue un jalon essentiel dans la postérité du cogito cartésien, et cela notamment à propos de la double interrogation sur l’ unité et l’ identité du moi qui caractérise la réception du cogito à partir de la fin du xvii e siècle.
La triada configuración-interacción-emergencia: una mirada compleja a los procesos de aprendizaje en el aula de Matemáticas
Authors: Hernández-Zavaleta Jesús Enrique , Carrasco Henriquez Eduardo Andrés , Carrión Velázquez Vicente 
Published: August 2022

El aula de Matemáticas es altamente compleja, organizada en múltiples niveles y con múltiples limitaciones. Dados los retos metodológicos para su investigación, este artículo propone a la triada configuración-interacción-emergencia como una aproximación compleja, sistémica y dinámica al aula. Sus bases teóricas están en las investigaciones de los procesos colectivos permeados por los estudios sobre la cognición humana de Maturana y Varela (1984). Esta investigación cualitativa identificó producciones textuales relacionadas con aspectos de la triada en dos experiencias de aprendizaje: (1) un taller sobre incertidumbre educativa con docentes de Matemáticas y (2) un estudio con estudiantes, de noveno y décimo grados, estudiando el péndulo doble. Los resultados mostraron a la triada como una categoría de análisis que favorece una aproximación sistémica del aula. Concluimos que la triada permite focalizar una mirada que no separa, sino que comprende el carácter sistémico y evolutivo de los procesos de aprendizaje en el aula de Matemáticas.
Mexica conquests, Castilian conquests: Castilian and native textual structures in the historical section of the Codex Mendoza
Authors: Gorobets Martins Eduardo Henrique 
Published: August 2022

After the conquest of Mexico-Tenochtitlan, the Mexica elites had to rethink their political role in the new society, which included rewriting their histories. One of the first colonial manuscripts containing Mexica histories was the Codex Mendoza, a document produced in 1541 by Mexica upon a request of Viceroy Antonio de Mendoza. The purpose of this article is to analyze the Codex Mendoza’s first section and highlight how the genre of European chronicles was used to structure the alphabetic texts, which are interspersed with the pictorial texts of native origin. It is argued here that the pictorial texts were reduced to illustrations for the Castilian alphabetic texts which, in turn, describe a set of information very similar to what is found in Castilian chronicles. The arrangement of the Codex Mendoza’s history and its Castilian texts demonstrate that native peoples’ pre-Hispanic submission to the Mexica have been projected forward in time, aiming at forming part of the Castilian domains appropriated after the conquest of Mexico-Tenochtitlan and the creation of the Viceroyalty of New Spain.Keywords: Mexica; codices; chronicle.

Dans les coulisses de l’affaire Calas
Authors: Bost Hubert 
Published: August 2022

Rendue célèbre par l’action de Voltaire, l’affaire Calas a aussi mobilisé deux hommes de lettres protestants dont l’action mérite d’être mieux connue. L’écrivain La Beaumelle, qui réside à Toulouse au moment où Marc-Antoine Calas est retrouvé mort (13 octobre 1761), rédige dans un premier temps plusieurs textes : La Calomnie confondue attribuée au pasteur Paul Rabaut, mais aussi les Observations pour le sieur Jean Calas signées Duroux. Après la condamnation à mort de Jean Calas pour le prétendu meurtre de son fils (9 mars 1762), il dresse un Mémoire « au Roy » où, après avoir rappelé les faits, il énumère douze motifs de nullité de l’instruction menée par le capitoul David de Beaudrigue : or la teneur de ce mémoire communiqué aux défenseurs de la mémoire de Jean Calas – notamment Voltaire et Court de Gébelin – inspirera leurs propres écrits. Enfin, au moment de la réhabilitation de Calas (1765), La Beaumelle tente de convaincre Anne-Rose Cabibel-Calas d’attaquer non seulement David de Beaudrigue et les capitouls, mais aussi la chambre criminelle du parlement de Toulouse. Quant à Court de Gébelin, c’est depuis Lausanne qu’il s’intéresse à l’affaire Calas. En 1762 il est d’abord consterné par l’exécution de son ancien étudiant François Rochette, puis ému par les malheurs de Pierre-Paul Sirven, accusé comme Calas d’avoir assassiné son enfant et qu’il se préoccupe d’accueillir sur les rives du Léman. Ses Toulousaines sont un recueil de lettres fictives dans lesquelles il entrelace le récit des trois affaires Rochette, Calas et Sirven en vue de démontrer le fanatisme antiprotestant de la capitale du Haut-Languedoc. Quoique traversées par un incontestable souci militant, elles n’en manifestent pas moins un réel souci d’objectivité dans le récit des affaires, pour lesquelles Court de Gébelin s’est efforcé de recueillir des témoignages les plus fidèles possibles. Pour des raisons de sécurité personnelle et par souci d’efficacité, La Beaumelle devait rester dans l’anonymat. Quant à Court de Gébelin, il publia bien ses Toulousaines mais leur diffusion fut freinée par l’hostilité des comités de Lausanne et de Genève puis par Voltaire qui préparait son Traité sur la tolérance. Bien qu’ils n’aient pas eu l’écho attendu, les écrits de ces deux hommes de lettres méritent d’être étudiés et peuvent être considérés comme des contributions significatives du protestantisme français de la seconde moitié du XVIIIe siècle. On se prend à imaginer ce qu’aurait été le destin de ce protestantisme si d’autres choix tactiques avaient été faits par ceux qui, en France ou au Refuge, prétendaient alors décider de ce qui lui convenait.
Medios virtuales para el trabajo colaborativo entre docentes: una revisión sistemática
Authors: Romero Torres Emiliano Ladislao , Andrade Díaz Elba María , Oblitas Pauccar Rosemary , Pacheco Saavedra Ana 
Published: August 2022

La presente revisión sistemática aborda el tema del trabajo colaborativo que los docentes han desarrollado empleando medios virtuales durante los últimos cinco años. El objetivo de la investigación fue analizar la evolución de la práctica docente gracias a los aprendizajes logrados por la interacción con sus pares en entornos virtuales. Para ello, se revisaron 54 artículos de cinco bases de datos: Scopus, Scielo, Alicia, Dialnet y Redalyc considerando los procedimientos metodológicos y el empleo de los operadores booleanos . Se concluye que como consecuencia del confinamiento, la práctica docente ha mejorado en los últimos años, como producto de la aplicación de las herramientas digitales necesarias en los entornos virtuales y debido a las facilidades que brindan los recursos informáticos. El aprendizaje colaborativo se ha fortalecido a través de las redes formales que se encuentran las constituidas por instituciones educativas, que pueden desarrollarse a través de plataformas dedicadas como Moodle o Gsuite, pero también mediante varias redes sociales como Facebook, WhatsApp, YouTube, o una mixtura de esta. Además, es fundamental priorizar la capacitación permanente del docente ante esta nueva necesidad para adaptarse al contexto de enseñanza-aprendizaje virtual.

The phenomenon of industrial development of Islamic Banking in Indonesia after the Act No. 10 of 1998 concerning Amendment to Law No. 7 of 1992 took place with so rapidly. This happens because in the era of the Law No. 1998 banking law development policies using dual banking system (dual banking system), the permissibility of conventional commercial banksprovider the service with the first form of Islamic Sharia (UUS). Provision of services easier by the existence of sharia office channeling concept (use of conventional commercial banks in servicing transactions with Islamic Laws, provided that the bank in question has had Sharia or abbreviated by the term UUS) as introduced in the Bank Indonesia Regulation (PBI) Amandement No. 8/3/PBI/2006 Operations Conventional Commercial Banks to Commercial Banks Conducting Business Based on Sharia Principles and Office Opening Bank Conducting Business Based on Sharia Principles by Conventional Commercial Banks as amended by Regulation No. 9/7 / PBI/2007. The core of the office channeling is that it allows a conventionalbank or conventional bank branches providing Islamic services without the need to first establishUUS but simply provides a special unit in the office of the bank in the form of a counter question.
