Análisis de los estereotipos de género a través de los refranes en El saber del pueblo (1890)
Authors: Martín Cuadrado Carmen 
Published: June 2024

La disciplina paremiológica, fruto de su carácter popular y generacional, ha sido una de las encargadas de divulgar y difundir pensamientos discriminatorios hacia las mujeres a través del lenguaje verbal, lo que ha dado lugar a estereotipos de género muy marcados. El objetivo del presente trabajo no es otro que analizar algunos ejemplos de paremias como la mujer y la pera, la que calla es buena; mula que hace bien y mujer que parla latín, nunca hicieron buen fin o dolor de mujer muerta dura hasta la puerta, que reflejan los roles que se han vinculado al universo femenino y que tienen cabida en las obras lexicográficas publicadas. A través del análisis de El saber del pueblo de Eduardo Orbaneja y Majada, repertorio publicado en el siglo XIX, se presentarán actitudes sexistas en las paremias.

Development and Validation of a Systematized Liquid Chromatographic Method for Estimation of Roflumilast in Tablets and in Presence of its Degradation Products
Authors: Panda Sagar Suman , Bera Ravi Kumar Venkata Varaha 
Published: June 2024

Background: Roflumilast (ROF) is an antiasthmatic drug used frequently for treating chronic obstructive pulmonary disease (COPD). The various reported methods developed with a non-systematised traditional workframe for routine estimation of ROF in formulations indicated the demand for developing a systematised new method.
Objective: In the present study, an attempt was made to develop a new validated liquid chromatographic method with federal flexibilities and stability-indicating potential.
Method: A time-efficient, rapid, and systematised quality by design (QbD) approach was developed to avail regulatory flexibilities with assured performance. Defining the analytical target profile (ATP) and associated critical analytical attributes (CAAs) helped control the method’s performance. Methanol proportion, flow rate, pH, and detection wavelength were the four identified critical method variables (CMVs) that were further studied for robustness investigation. Moreover, the control strategies for CMVs were defined as per method intent. Chromatography constituted methanol: water (pH 3.5 maintained by orthophosphoric acid) (90:10% v/v) as the mobile phase, flowing at 1.2 ml/min on a ShimPack GWS C18 column. The photodiode array (PDA) detector provided the best results at 250 nm.
Results: ROF was eluted at a retention time of 3.1 min with acceptable system suitability values. Validation studies postulated method acceptability and suitability. Results for parameters viz. linearity (0.5–160 µg/ml), accuracy (> 98%), and precision (< 1%) advocated method reliability. ROF was susceptible to applied acidic and alkaline stress, requiring adequate preventive measures during formulation development.
Conclusion: Overall, this method worked well for figuring out ROF even when there were product additives and possible degradation products present, showing that it can be used on a regular basis.

The activities of the Social Security Department of the Pskov city Administration during the years of occupation (1941-1944).
Authors: Khrishkevich Tatiana 
Published: June 2024

The article examines the social practices of the civil occupation authorities of the city of Pskov in 1941-1944. The article analyzes the reasons for the provision of social assistance, its varieties, and size. Assistance was entrusted to the social department of the Pskov City Administration, which compiled survey reports, visiting the housing of the poor and disabled. Among the measures were bread and fuel cards, as well as the provision of housing and medical care. The publication is based on documents located in the State Archive of the Pskov region. The activities of the social security department of the Pskov city Administration during the years of occupation are reviewed on the basis of archive materials, the funds of which also contain data from the trade and financial departments of Pskov dealing with payments to the population. The residents who remained in the city did not represent an exceptionally able-bodied community. They were often disabled people, children and women who, for various reasons, could not evacuate. They were unable to work either for health reasons, or because of their age, or because their specialty turned out to be unclaimed by the occupiers. As a result, the author comes to the conclusion about the limited and unsatisfactory amount of social support for residents of occupied Pskov. Social support, although organized by the city administration department, was in practice coordinated with the German commandant&apos;s office, which was the source of genuine power. The funds allocated by the department were so insignificant that they did not allow them to live even for a week. The prices of groceries in stores and on the market were incredibly high. Cash flows to the department were also extremely limited. Survival in occupied Pskov, as in any Nazi-occupied city, turned into a fierce struggle for life. By the time of liberation, less than a thousand people remained in the city from the pre-war more than 60 thousand people.
The Place of the Military Revolutionary Organizations of the Estonian Region in the Process of Approving the Authorities of the Soviets During the Period of the Russian Revolution
Authors: Egorov Igor 
Published: June 2024

The dramatic events of the great Russian revolution of 1917, which to a certain extent became the catalyst for major global changes, are one of the turning points of world history that led to the onset of the modern era. The historical upheaval caused by these events influenced the change in many vectors of further development both directly of our country and of the world community as a whole. At the same time, modern domestic historiography often forgets or underestimates the prominent role that Estonian military-revolutionary organizations played in establishing this power at the very beginning of its formation. Meanwhile, the leadership of the Bolshevik Party reasonably considered Estonia as one of the most important bridgeheads of the political coup prepared in October 1917.
In this regard, it is important to take into account not only the geographical position, but also the socio-economic and military-strategic importance of the Estonian region for the entire North-West of Russia. On the eve of the 1917 revolution, the Estland province was one of the largest industrial centers of the Russian Empire. At this time, a kind of agglomeration developed between Revel (modern Tallinn) and Petrograd (St. Petersburg), or more precisely conurbation (from Latin con – «together» and urbs – «city»), which included a network of industrial zones, ports, arsenals, military bases, etc. In the conditions of the long First World War, it was also one of the most important bases of the Baltic Fleet and the closest rear area for the troops of the Northern Front, which covered Petrograd from the Kaiser army. On October 23, 1917, revolutionary troops and detachments of the Red Guard captured railway stations, mail, telegraph and other strategic objects in Revel. Commissars of the Estonian Military Commissars were sent to military units, ships and institutions. Thus, the control of the pro-Soviet forces in Tallinn was established even after the beginning of the armed uprising in Petrograd (October 24-25, 1917) and, in fact, was a dress rehearsal for the latter.
Thus, the Estonian Military Revolutionary Committee, even a day before the start of the open speech of the Bolsheviks to seize key positions in Petrograd, took control of all the strategically important points of Revel, put revolutionary military units and the fleet on alert. As a result of these actions, Estonian military-revolutionary organizations blocked the path of counter-revolutionary units trying to move in the direction of Petrograd. Without achieving all of their original goals, Estonian military revolutionary organizations made a notable contribution to the Bolshevik power-building in the earliest days of Soviet power in Russia, when its position here was still extremely unsustainable.
The Images of Sacred Trees in Ancient Egyptian Fairy Tales
Authors: Mironova Alexandra 
Published: June 2024

The paper examines the semantics of trees described in the ancient Egyptian fairy tales “Tale of Two Brothers” and in the “Story of Sinuhe”. The purpose of the study is to identify the semantics of trees in these fairy tales, their relationship with the religious ideas of the Egyptians and specifies of ideas about the calendar cycle displayed in these texts. The author traces literary parallels between the images of fairy-tale trees and the motifs of the “Book of the Dead”, which tells about the posthumous life of the soul of the deceased in the Netherworld.

The study reveals that in the “Tale of Two Brothers”, the cedar and two persea trees are correlated with the Osiris and solar cults. The persea trees represent the rays of the sun, Osiris and the deceased as the blessed spirit Akh. The cedar inflorescence located at the top of the tree is also associated with the image of the sun. It was found that in this fairy tale, the description of tree life and the hero’s repeated birth reflect the change of calendar cycles from the flood season to the harvest season, from the period of visibility of celestial bodies and plants to the period of their invisibility. The sycamore, mentioned in the “Story of Sinuhe”, is the sacred tree of Hathor, Isis and Nut and appears as a symbol of the heaven with which these goddesses were associated.

L’histoire du chemin de fer au Cameroun. Entre défis internes et enjeux géopolitiques
Authors: Manceau Elodie , Antoniazzi Federico 
Published: July 2024

Le développement du chemin de fer au Cameroun s’inscrit au cœur de nombreux enjeux multiscalaires. À l’échelle du continent africain, la lutte d’influence entre la Chine, l’Europe et les États-Unis implique de nouveaux choix d’investissement. À l’échelle régionale, la présence de Boko Haram dans l’extrême nord et la crise anglophone dans l’ouest du Cameroun influent sur le développement du réseau ferroviaire et l’accessibilité des territoires. Au niveau national, le chemin de fer, puissant levier d’unification au lendemain de l’indépendance, demeure essentiel en tant qu’outil politique, social et économique, en dépit de la concurrence du mode routier et d’une architecture institutionnelle et contractuelle critiquée par les pouvoirs et l’opinion publique. Ce cadre général complexe interroge par conséquent les acteurs mobilisés et les choix techniques pour la réalisation du réseau, hérité de l’époque coloniale. Le modèle de gouvernance, instauré voire imposé par les bailleurs de fonds et les actionnaires privés, répond-il au principe d’une gestion économique efficace en faveur des intérêts socio-économiques des territoires traversés et des populations desservies ? Cet article apporte une réponse à cette question, en analysant le rôle des bailleurs des fonds dans les logiques géopolitiques actuelles, au regard de la nouvelle politique chinoise des routes de la soie (Belt and Road Initiative), ainsi que de la politique européenne Global Gateway , en faveur du développement des corridors de transport en Afrique.
De L’Histoire véritable au boulet de Jules Verne : une histoire science-fictionnelle des paradigmes astronomiques
Authors: Blanquet Estelle , Picholle Éric 
Published: June 2024

La légende dorée de l’astronomie moderne réduit souvent son histoire à deux moments marquants : la « révolution copernicienne » et le défi de Galilée à l’obscurantisme présumé de l’Église. Inévitablement, son histoire réelle s’avère plus riche et plus subtile, en interaction permanente avec l’imaginaire scientifique de son temps. Nous proposons de la relire à la lumière de l’histoire de la science-fiction, d’examiner de quelle manière celle-ci a pu contribuer à déstabiliser les paradigmes astronomiques du passé et de tenter d’identifier quelques enjeux didactiques associés à ces changements conceptuels. Les auteurs de SF, adeptes du pas de côté, offrent en effet à qui sait les repérer des situations facilitant l’identification par les élèves de choix liés à des simplifications paradigmatiques jamais questionnés ; à charge alors à l’enseignant de construire un dispositif leur permettant de mieux les comprendre pour dépasser les arguments d’autorité et mieux accepter les changements de paradigmes proposés. Nous identifierons dans un premier temps, de façon non exhaustive, des œuvres de SF classiques et d’autres qui le sont moins dont le potentiel de déstabilisation des paradigmes astronomiques peut être exploitable en classe. Nous montrerons par ailleurs comment des processus similaires sont à l’œuvre dans des images de science fiction, comme « La Terre encadrée » de Manchu et illustrerons alors par quelques exemples de séquences en démarche d’investigation la façon dont ces œuvres peuvent être utilisée dans le cas des paradigmes astronomiques.
