modas a escala colectiva: Walter Benjamin y las figuras de la mujer en la ciudad moderna
Authors: Goldwaser Nathalie
Published: December 2023

Este artículo abreva fundamentalmente en el Konvolut B [Moda] perteneciente al Libro de los Pasajes (Das Passagen-Werk) escrito entre 1927 y 1940 y publicado póstumamente. Allí se revela uno de los fenómenos de la cadena infernal de la modernidad y del capitalismo: la moda.Lejos de ser una noción vinculada a la indumentaria, al ornamento o al adorno, a la mujer o las mujeres, Benjamin logró que la moda sea desmitificada revelando sus características internas: la de estar vinculada con el pasado, con la tradición para introducir una innovación que al cabo caducará con el fin de que renazca, como el continuum de la historia, en una nueva moda. Si la moda se introduce a través de la ciudad, ¿qué papel jugó esta y qué vinculaciones se dan en torno a las figuras de la mujer en este Konvolut? Nos proponemos desentrañar esa articulación que haría del escrito del filósofo alemán una revelación por demás sugestiva: la de encontrar en la moda una barrera que levantan las clases altas para distinguirse de las bajas tal como Haussmann lo hizo en la ciudad de París para limitar el accionar de las barricadas.
Lo imposible es imposible hasta que lo haces posible
Authors: Sigüenza Reyes Francisco Javier
Published: December 2023

Hace veinte años se publicó en México el ensayo de Walter Benjamin, La obra de arte en su época de reproductibilidad técnica, traducido por Andrés Echeverría Weikert y con un texto introductorio de Bolívar Echeverría, titulado “Arte y utopía” (Editorial Ítaca, México, 2003). Aprovechando la visita de Andrés a la Ciudad de México, quien reside actualmente en Quito, tuvimos la oportunidad de conversar con él sobre algunas cuestiones en torno a las dificultades que implicó la traducción del texto de Benjamin, la importancia de la labor traductiva y de la relevancia de las reflexiones de Benjamin sobre la técnica para nuestro presente.
posthumano en clave ética
Authors: Farrán Roque
Published: December 2023

En este ensayo deseo retomar ciertas ideas básicas del Posthumanismo para mostrar la necesidad de leerlo en clave ética, entendida ésta como una práctica de sí que exige realizar ejercicios de lectura, meditación y escritura, a partir de reconsiderar nuestra tradición de pensamiento y recuperar la relación inmanente con la naturaleza de la cual formamos parte. Considero que aun es posible practicar la filosofía como un saber racional que hace cuerpo y permite afrontar la muerte personal e incluso la extinción total. Que el mejor antídoto contra la desesperación sigue siendo un uso de los saberes que pueda interpelar a las transformaciones políticas necesarias para vivir mejor en un medio cada vez peor.

The blanching process is used to prevent the action of enzymes that cause the loss of taste, color and texture of vegetables and fruits. Blanching also removes some surface dirt and inactivates microorganisms, brightens the color, softens and helps to slow down the loss of vitamins. In the present studies, attention is focused on the selection of optimal regimes for the process of blanching vegetables, in which peroxidase activity is suppressed, while vitamin C and β-carotene are preserved. To determine the optimal blanching modes for different durations, the following were used: steam treatment of the sample, treatment with hot water at a temperature of 950C, and blanching with microwave radiation. As a result of the research, it was found that blanching the studied samples with steam for 120 seconds and microwave treatment for 90 seconds for carrots and 60 seconds for pumpkin are more gentle processing methods compared to boiling, and it is these methods that should be used for further research. The results showed that microwave treatment was the most effective in terms of peroxidase inactivation compared to steam and hot water. Boiling as a blanching method is undesirable, since with this method, when the maximum inactivation of peroxidase is reached, there is an increased destruction of vitamin C and β-carotene.

The article considers the improvement of methods for testing the color fastness of textile materials with the replacement of the visual method with an objective colorimetric evaluation method. A new method for testing the color fastness of textile materials is proposed. The analysis of domestic and foreign standards that establish the calculation and establishment of color fastness standards for cotton fabrics and their comparison with the norms of international and domestic standards was carried out. It is shown that the development of methods for instrumental determination of color fastness to friction, which is an alternative to the method of visual assessment of the color fastness of any textile material on a gray scale, is currently an urgent and promising scientific and technical task. A new method for testing the color fastness of textile materials is proposed. The overall color difference (ΔE) between the test sample of the color fastness test material and the original sample was measured. For both samples, the over-all color difference was determined in the CIEL*a*b* system, the values of which are converted into equivalent points on a gray scale. The score in terms of the value of ΔE was calculated on a computer using the Ecsel environment and displaying the calculation results on the display screen.

Extraction was carried out on a semiautomatic Soxhlet apparatus using ethanol and water as a solvent. The objectives of this study were to identify the available phenolic compounds of the pericarp of a milky walnut by the extraction method, and in the future the resulting extract is planned to be used as a food additive to enrich the missing food elements. The optimal extraction modes were also identified, in which the most complete extraction of phenolic compounds is observed. As a result, it wаs fоund thаt thе grinding indеx оf thе wаlnut pеriсаrp directly affects the yield of phenolic compounds, and according to the results of the study, the pericarp, crushed to 300 μm, gave the maximum yield of phenolic compounds. The optimization results showed that when extracting with 90% ethanol, the extraction time was 150 minutes, while the yield of phenolic compounds was the highest, also when extracting with the extractant "ethanol + water" in a ratio of 80/20, the extraction time was 120 minutes, with this was the maximum yield of the extract. Walnut pericarp extract has been shown to have high antioxidant activity compared to synthetic antioxidants such as BHT, BHA and TBHQ.

Authors: Aldiyeva A. B. , Khamitova D. D.
Published: December 2023

Strawberry berries are a valuable product rich in vitamins, anthocyanins, and polyphenolic compounds that have antioxidant effects on human health. However, due to the deterioration and seasonal availability, the issue of their long-term storage is highly relevant. Freeze-drying, a modern preservation method, preserves their properties during storage. Since the drying process can affect the appearance, nutrient content, and antioxidant activity of berries, the purpose of this study was to investigate the effects of freeze-drying parameters on the content of anthocyanins and polyphenols in Albion variety strawberries. The heating temperatures of the freeze-drying were 35°C, 40°C, 45°C, and 50°C, and the sublimation process times were 18, 20, and 22 hours. Optimal conditions were found: a shelf temperature of 45°C and 18 hours of drying. These conditions preserved both the strawberries' initial qualities and their high anthocyanin content, with only an 8.4% decrease. Similarly, polyphenol content decreased by 3.9%, while the strawberries maintained strong antioxidant activity.

Published: December 2023

The demand for natural and functional food products is constantly increasing, driving the research on new ingredients and technologies to enhance the quality and safety of meat products. This literature review focuses on the application of new functional ingredients and traceability of meat products to ensure their quality. The study examines the surface treatment of meat with bioactive substances such as dihydroquercetin from Larix sibirica Ledeb, rosemary extract (Rosmarinus officinalis), and distilled rose petal extract (Rosa damescena Mill.). Additionally, the inclusion of functional ingredients such as dried goji berries (Lycium barbarum) and pumpkin (Cucurbita moschata) in meat matrices is discussed. The research highlights the potential benefits of these functional ingredients in inhibiting lipid oxidation, preserving color, and improving the taste qualities of meat products. The inclusion of natural antioxidants and bioactive compounds derived from plants presents a promising alternative to synthetic additives. Furthermore, the reduction of potentially harmful substances, such as nitrites, in meat products is achieved through the inclusion of functional ingredients. To ensure the quality and safety of these functionally processed meat products, a traceability system is proposed. This system includes documentation of ingredient origin, production processes, and packaging information. Implementing a traceability system enables the tracking of product movement and distribution throughout the supply chain, thereby confirming the positive effects of the ingredients and ensuring consumer trust. The aim of this article is to integrate new functional ingredients and implement a traceability system to enhance the quality, safety, and acceptability of meat products by consumers. These approaches align with the growing demand for natural and high-quality food products, opening opportunities for innovation in the meat industry. Funding information: The materials were prepared within the framework of the "Zhas Galym" project within the scientific and technical program AP15473123 "Digitalization of the traceability system of meat products to improve the quality of semi-smoked sausages during long-term storage" of the budget program 217 "Development of Science" subprogram 102 "Grant financing of scientific research" of the Ministry of Science and Higher Education of the Republic of Kazakhstan for 2022-2024.

Os evangélicos e as paisagens do medo
Authors: Carvalho Caê
Published: December 2023

Apresenta-se a constituição do bairro do Engenho Velho da Federação (Salvador-BA) pelo prisma da paisagem do medo para os evangélicos da Igreja Universal. A pretensão é mostrar, à luz da experiência religiosa, da experiência do sacro segundo o referido credo, como se molda a própria percepção do bairro como um espaço topofóbico e de sua paisagem como aterrorizante para o grupo em pauta. Nesta tarefa, será necessário explorarmos a religião enquanto forma simbólica, uma vez que, a partir da veste religiosa, a assumpção do credo estrutura um modo de atuação e de compreensão do mundo. E são justamente tais representações, aliadas à constituição material e simbólica do lugar, interpretando essa própria constituição, que a paisagem do medo se conforma.

Published: December 2023

This article aims to present a study on the insertion of advertising practices in digital games, this being within the servers of the game Grand Theft Auto Roleplay (called GTA RP), an illegitimate modification of the game Grand Theft Auto V by the developer Rockstar Games. It is worth mentioning that GTA RP is nothing more than a base platform for GTA V, which supports a large number of players simultaneously and allows partial customizations in the game map, in which the brands that we will discuss used this resource to carry out activations at the along the Cidade Alta server, this being a kind of functional city in satire of the real world. In addition, more than identifying the brands in the game, the study seeks to verify the ad formats and their possible impacts on the player's perception of such brands presented within this universe. In short, it is understood that digital games have been an important media channel in our society, capable of reaching new consumer niches, in which brands were able to visualize in their structure countless possibilities for the insertion of advertising messages.

Published: December 2023

In Zambia, the situation of women in positions of power remains a sensitive and controversial issue. Women are mostly subjected to preconceptions that place them in challenging situations. This study sought to explore the experiences of women in management positions, and to examine the hindrances that these women leaders encounter. Using a qualitative strategy, thirty five women in school management positions were purposefully sampled from the research field comprised of seven secondary schools located in Lusaka District. Questionnaires, interview guide and focus group discussions were utilized as tools to gather data. Findings revealed that women administrators have hidden talents and competencies, as they perform in an ethical manner using different leadership styles. Yet, as showed in the results, women administrators experience a number of challenges and hurdles that stand in their pathways or occur when performing their leadership roles. The current study advocates for getting rid of unnecessary and harmful prejudices that prevent women from arise in order to allow them to express their inner potential. Besides, this study suggests more women should come on board and share their experiences in management positions so that other women who may wish to join them have some ideas of where to start from. Therefore, is a need to empower women not only by bridging the gap that exists between men and women,

Published: December 2023

Este artículo reflexiona sobre los dilemas que atravesaron países como Ecuador y México durante la pandemia de COVID-19. En un escenario en donde era confuso saber el proceso de contagio y qué se debía hacer con los cuerpos enfermos y con los cuerpos muertos debido al virus, los rumores contribuyeron a crear pánico e inseguridad en los individuos que conforman una comunidad. Más aún cuando se reportaban “cadáveres abandonados en las calles”. Además, se expone, a partir de los datos recolectados, las formas en las que el estado generó un discurso en donde el cuerpo enfermo y muerto fueron los cuerpos de los que se sospecha, los “enemigos públicos” de la ciudadanía. Además, reflexiona sobre el papel crucial del cuerpo para entender el ritual funerario y las diversas formas de cómo enfrentaron algunos pacientes y familiares la enfermedad y la muerte en aquel contexto carente de certezas.
Adsorption of hexavalent chromium from aqueous solution onto corn cobs – activated carbon
Authors: BOZBEYOGLU Pınar , GÜNDOĞDU Ali
Published: December 2023

This study evaluated the performance of a new activated carbon (CCs-AC) produced from corn cobs by boric acid activation for the effective removal of hexavalent chromium, a heavy metal with high potential to pollute the environment, from wastewater. For this purpose, with the help of parameters such as solution pH, contact time, initial Cr(VI) concentration, CCs-AC dose, desorption and temperature, the removal of Cr(VI) ions from aqueous solution by adsorption on CCs-AC was investigated from equilibrium, kinetic and thermodynamic point of view. As a result of the experiments, it was determined that the optimum solution pH was 2.0, the contact time was 4 hours, and the desorption solution was 3.0 M NaOH. From the kinetic data, it was determined that the adsorption was compatible with the pseudo-second order kinetic model and the maximum Cr(VI) adsorption capacity (123.7 mg/g) obtained from the Langmuir isotherm model showed that CCs-AC was of competitive quality with the literature. From the thermodynamic data, the positive ΔH value indicates that the adsorption is endothermic and the value of 12.00 kj/mol indicates that the adsorption is rather chemically driven. The negative ΔG value indicates that the process proceeds spontaneously with an increase in temperature, while the ΔS value indicates an increase in the amount of unused energy.

O presente trabalho vem relatar os grandes problemas enfrentado pelo Brasil muito antigo no sistema carcerário que é a superlotação das celas, o domínio do sistema por facções criminosas, bem como a insalubridade, a proliferação de epidemias e o consumo de drogas nas unidades, esses são uns dos muitos problemas que o brasil enfrenta para ressocializar um detento que será entregue a sociedade sem ter entendido qual foi o intuito de cumprir a pena e terá uma grande probabilidade de retornar a uma penitenciária, pois o devido papel da prisão do detento não foi cumprida de forma devida gerando um caos para o estado e para o detento que não ressocializado. A pesquisa investiga o impacto da superlotação nas condições de vida dos presos e na reintegração, destacando a necessidade de uma abordagem mais preventiva do Direito Penal e investimentos em programas de reabilitação. As dificuldades na ressocialização são obstáculos reais e complexos. A falta de investimento em programas de capacitação profissional e educação dentro das prisões, combinada com a estigmatização social, cria desafios significativos para a reintegração dos detentos na sociedade. Para superar essas dificuldades, é imperativo investir em educação, capacitação profissional, assistência pós-penalidade e conscientização pública.

OS EFEITOS DO USO IRRACIONAL DOS ANTIBIOTICOS
Authors: Puresa Thaylane de Souza , Carvalho Fabiano Lacerda
Published: December 2023

O uso irracional de antibióticos tem efeitos nocivos à saúde e à sociedade. Primeiro, leva ao surgimento de bactérias resistentes a esses medicamentos, dificultando o tratamento da doença. Além disso, o uso desnecessário de antibióticos pode levar a efeitos colaterais adversos, como alergias e distúrbios gastrointestinais. A autoadministração de antibióticos também é um problema, pois muitas pessoas os utilizam sem a devida prescrição médica, isso pode levar ao agravamento das infecções e ao desperdício de recursos médicos, e um dos principais fatores para que as bactérias desenvolvam resistência é o uso contínuo de antimicrobianos sem orientação profissional, levando a altos níveis de resistência aos medicamentos. Medidas como a sensibilização do público, a educação dos profissionais de saúde e a implementação de políticas de controle são fundamentais para combater o uso irracional de antibióticos e manter a eficácia destes medicamentos tão importantes mantendo assim o controle dos impactos do uso errôneo desse medicamento em  nosso organismo.

Mesoscale permeability variations estimated from natural airflows in the decorated Cosquer Cave (SE France)
Authors: Pellet Hugo , Arfib Bruno , Henry Pierre , Touron Stéphanie , Gassier Ghislain
Published: December 2023

Abstract. Conservation of decorated caves is highly dependent on airflows in the karst network and through the surrounding host rock. Airflows are driven by pressure gradient and influenced by the shape of the karst conduits and the permeability of the carbonate rock massif. The Cosquer cave is an Upper Paleolithic decorated cave, half drowned in a coastal karst, where conservation is also dependent on the cave’s pools connected to the sea. Hydroclimatic data, such as air pressure and temperature and water level inside and outside the cave have been measured for several years to identify the main processes governing the water level variations, the airflows and the air renewal. Data show an unusual behavior for a karst: the karst air pressure is nearly always higher than the atmospheric pressure. As a result, the water level in the cave is below the sea level. The daily variations of the sea tide provide an assessment of the cave volume above the pools water level. Although the cave air is confined by the rock and the seawater, there are also external air inflows during short pressurization events. Moreover, the carbonate rocks effective permeability to air at the massif scale is inferred from the cave air pressure decrease over the summer season, by applying Darcy’s law in a partially-saturated medium. Six years of data show that permeability varies from year to year, and according to the cumulated rainfalls during the spring and summer. The driest years are correlated with a higher permeability, a faster air pressure decrease in the cave and a faster rise of the pools water level. In the future, in the context of climate change, a perturbation of the rock permeability is then expected in the near surface caves, which will impact airflows in decorated caves and may alter their fragile hydroclimatic stability.

Abstract. Climate change is a global challenge with multiple far-reaching consequences, including the intensification and increased frequency of many extreme weather events. In response to this pressing issue, we present ClimaMeter, a platform designed to assess and contextualise extreme weather events relative to climate change. The platform offers near real-time insights into the dynamics of extreme events, serving as a resource for researchers, policymakers, and being a science dissemination tool for the general public. ClimaMeter currently analyses heatwaves, cold spells, heavy precipitation and windstorms. This paper elucidates the methodology, data sources, and analytical techniques on which ClimaMeter relies, providing a comprehensive overview of its scientific foundation. To illustrate Climameter, we provide four examples, the December 2022 North American Winter Storm, the August 2023 Guangdong – Hong Kong Flood, the late 2023 French Heatwave and the July 2023 windstorm Poly. They underscore the role of ClimaMeter in fostering a deeper understanding of the complex interactions between climate change and extreme weather, with the hope of ultimately contributing to informed decision-making and climate resilience.
Climate and ablation observations from automatic ablation and weather stations at A. P. Olsen Ice Cap transect, NE Greenland, May 2008 through May 2022

Published: December 2023

Abstract. The negative surface mass balance of glaciers and ice caps under a warming climate impacts local ecosystems, influencing the volume and timing of water flow in local catchments, while also contributing to global sea level rise. Peripheral glaciers distinct to the Greenland ice sheet respond faster to climate change than the main ice sheet. Accurate assessment of surface mass balance depends on in-situ observations of near-surface climate and ice ablation, but very few in-situ observations of near-surface climate and ice ablation are freely available for Greenland’s peripheral glaciers. The transect of three automated weather and ablation stations on the peripheral A. P. Olsen ice cap in northeast Greenland is an example of this much needed data. The transect has been monitored since 2008, and in 2022 the old weather and ablation stations were replaced by a new standardized setup. In order to ensure comparable data quality from the old and new monitoring station setups, it was necessary to re-evaluate the data collected between 2008 and 2022. This paper presents the fully reprocessed near-surface climate and ablation data from the A. P. Olsen ice cap transect from 2008 to 2022, with a focus on data quality and the usability for ice ablation process studies. The usability and some quality issues are exemplified by using the data in an energy balance melt model for two different years. We showed that the inherent uncertainties of the data resulted in an accurate reproduction of ice ablation for just one of the two years. A transect of three automatic ablation and weather stations of this length is unique for Greenland’s peripheral glaciers and it has a broad scale of usage from input to climate reanalysis to detailed surface ablation studies. The dataset can be downloaded here: https://doi.org/10.22008/FK2/X9X9GN (Larsen and Citterio, 2023). Future refinements will be uploaded as new versions and the continuation of the transect time series are available via https://doi.org/10.22008/FK2/IW73UU (How et al., 2022).
Minimal variance-based outlier detection method using forward search model error in a leveling network
Authors: Durdağ Utkan Mustafa
Published: December 2023

Abstract. Conventional and robust methods are based on the additive bias model, which may cause type-I and type-II errors. However, outliers can be regarded as additional unknown parameters in the Gauss-Markov Model. It is based on modeling the outliers as unknown parameters, considering as many combinations as possible outliers selected from the observation set. In addition, this method is expected to be more effective than conventional methods as it is based on the principle of minimal variance and removes dependency in iterations. The primary purpose of this study is to seek the novel outlier detection approach efficiency in the geodetic networks. The efficiency of the proposed model was measured and compared with the robust and conventional methods by the Mean Success Rate (MSR) indicator for different types and magnitudes of outliers. Thereby, this approach enhances the MSR by almost 40–45 % compared to the Baarda and Danish (with the variance unknown case) method for multiple outliers (i.e., 1<m<4). Besides, the Forward Search of Model Error (FSME) is 20–30 % more successful than the others in the low controllability observations of the leveling network.
AN IMPROVED IMAGE REGISTRATION ALGORITHM FOR THERMAL INFRARED AND PANCHROMATIC IMAGE BASED ON GEOMETRIC STRUCTURAL PROPERTIES
Authors: Xie J. , Lv X. , Chu C. , Liu R. , Mo F. , Li B. , Wang C.
Published: December 2023

Abstract. In order to improve the image registration accuracy of heterogeneous remote sensing images with large radiation differences, an improved image registration algorithm for thermal infrared and panchromatic images is proposed. This method uses the phase consistency of intensity and direction to construct a geometric structure feature descriptor called the Histogram of Oriented Phase Congruency (HOPC) for image registration. It employs the Curvature Scale Space (CSS) corner detection to concentrate and extract feature points in contour areas, and defines a similarity metric (called HOPCn) based on the Euclidean distance between the descriptors for high-precision heterogeneous images registration. Five sets of panchromatic and thermal infrared images were selected for verification. The results show that the improved algorithm can match the homonymy points around the image contour, and the Correct Matching Rate (CMR) is improved by 2.7% and the Root Mean Square Error (RMSE) is improved by 3.7% compared to the original algorithm. This proves that the proposed method has good robustness under conditions of large radiation differences.

Abstract. Time-of-Flight (ToF) cameras have gained prominence in robotics, augmented reality, and gesture recognition due to their costeffective direct measurement of 3D environments. However, their outdoor applications remain limited, mainly due to challenges like sunlight interference. Through systematic testing under challenging outdoor conditions, we aim to assess the suitability of ToF cameras, specifically Azure Kinect and Pmd Monstar, in smart city contexts and contribute to the state-of-the-art and future trends of 3D sensing technology. Our experiments focus on three high-reflectivity cases: license plates, reflective road marking paint on cement and asphalt boards, and traffic cones. Results indicated that Azure Kinect offered a longer measurement range but was more susceptible to flying pixels. Pmd Monstar provided more stable depth measurements and was less sensitive to flying pixels. Differences in performance were attributed to their modulation frequencies and the distinct approaches to handling low-confidence points. By addressing the identified limitations and challenges, researchers and engineers can enhance ToF camera capabilities, ultimately improving their performance and expanding their applicability in outdoor transportation, autonomous driving, and other related smart city fields.

Abstract. This paper presents an investigation into the interoperability of 3D building energy data management, delivery, processing, and visualization via web clients using Open Geospatial Consortium – Application Programming Interface (OGC API) standard-based data models and web interfaces. Specifically, the OGC API – 3D GeoVolumes enable access to 3D city model geometries and semantics on the web, the OGC API – Features support the 2D version of the same geospatial data, the OGC API – Processes are used for CityGML analytics and building energy computation with the SimStadt urban simulation software and the OGC SensorThings API is utilized to manage related spatiotemporal or time-series datasets. The efficacy of this approach has been demonstrated in the OGC Testbed 18 Innovation Program, which highlighted the capacity of OGC API web services to synchronize building energy data and computation results between client and server for the case study of Helsinki, Finland, and Montreal, Canada. The advantages of using OGC API services for 3D building energy data interoperability are discussed, and it is suggested that the use of OGC API be promoted to the general public as well as extended to other domains and on a larger scale in future research.

La invasión de Ucrania tiene un impacto desigual en el Norte de África y Oriente Medio (MENA). Lógicamente, el escenario donde se desarrollan las operaciones militares está sufriendo directamente las consecuencias de una agresión ilegal, al margen por completo del Derecho internacional público, que en ningún caso autoriza una agresión de estas características. El resto del continente europeo también se ve afectado por las consecuencias de la agresión rusa observando con inquietud los efectos políticos, económicos y humanitarios de una guerra que se desarrolla al otro lado de su frontera. Otros Estados del mundo observan desde la lejanía y con la decisión de condenar la agresión o posicionarse en una neutralidad ambigua. Los menos —Siria, Bielorrusia, Malí, Eritrea, Nicaragua y Corea del Norte— apoyan la agresión de Rusia.
Russia after the Euromaidan Foreign Policy Limitations amid Clashing Geostrategies of Territorial Expansion and Eurasian Integration
Authors: Pardo Sauvegeot Eric
Published: December 2023

Tras el Euromaidán, Rusia respondió con una intervención militar en territorio ucraniano. Esta revisión del status dio un giro más brutal en febrero de 2022. Las razones del revisionismo de Rusia encajan en el debate sobre el creciente distanciamiento entre la Federación Rusa y Occidente, junto con una renovación de la caracterización clásica de Rusia como un Estado “imperialista” empeñado en restaurar el poder de la ex Unión Soviética centrado en Moscú. Aunque la caracterización amplia de Rusia como “imperialista” capta hábilmente su brutal negación de la soberanía de Ucrania, todavía combina diferentes vectores geográficos y períodos históricos. Este artículo contribuye a los debates en curso empleando los conceptos de “perspectivas geoestratégicas” de William Walters (es decir, marcha, frontera colonial y limes) y los modelos geopolíticos westfalianos e imperiales de Christopher S. Browning y Pertti Joenniemi. Este marco resume, por un lado, la compleja compatibilidad de los procesos de revisionismo territorial y, por el otro, la integración regional de la ex Unión Soviética centrada en Rusia. En última instancia, el objetivo es analizar la política fronteriza de Rusia posterior al Euromaidán, abordando tanto la revisión de las fronteras de Ucrania como la integración regional a través de la Unión Económica Euroasiática durante el statu quo que duró hasta 2022. El panorama resultante muestra que el modelo geopolítico westfaliano de la Federación Rusa de expansión del limes contradice el modelo geopolítico imperial basado en la creación de fronteras coloniales. El refuerzo incremental del modelo westfaliano desde febrero de 2022 plantea la interesante pregunta de cómo afectará esto a la geopolítica imperial con respecto a otros países de la ex Unión Soviética.

This qualitative study was designed to explore the manifestation of post-partum depression in men. There are growing number of fathers who undergo through this condition and are not self-aware because lack of recognition to this concept. This study found how men tend to experience this phenomenon and how it affects their lifestyle by using phenomenological approach. Purposive sampling was used to approach the sample. A sample of 15 participants were reached out through purposive sampling approached to screen out the symptoms of post-partum depression among men by using a screening tool of Edinburgh Postnatal Depression Scale (EPDS). Nine participants out of 15 were found to have post-partum depressive symptoms. Only 7 out of 9 participant’s data was taken in main study after reaching at saturation point from semi-structured interview. Collected responses were transcribed and themes were generated through reflective thematic analysis (Saldana, 2021; Barun & Clarck, 2019). From the analysis, four major themes were generated from the study; sense of un-involvement, chaotic experiences, transitional phase and partner induced post-partum depression. These themes were divided into sub-themes that thoroughly discussed the demonstration of this phenomenon in men. The study was intended to instill a great sense of awareness among the public about the phenomenon of post-partum depression in fathers that tends to exist.
Gênero, "raça" e educação: em defesa de uma abordagem decolonial do currículo escolar e das práticas pedagógicas
Authors: Prado Vagner Matias do , Faria Cássio Rodrigues
Published: December 2023

O discurso falocêntrico ainda é muito vivo na sociedade brasileira. Essa vividez é um dos reflexos dos processos históricos, sociais e culturais, em que os diferentes corpos se encontram, regulados em uma matriz de poder masculina/heterossexual/reprodutiva/branca/cristã que produz desigualdades. Dessa forma, este artigo tem como objetivo problematizar as relações entre currículo escolar, gênero e a partir da perspectiva decolonial. Para isso, e inspirados no método ensaístico, analisamos os estudos de autores e autoras que relacionam o currículo, a colonialidade do poder e a construção do gênero como produção de uma sociedade que reitera valores excludentes. Entendemos que as práticas escolares precisam contextualizar a realidade que vivenciamos e, sobretudo, tensionar processos histórico, social e cultural que constroem e regulam as diferentes subjetividades. Apontamos como caminho a decolonização do currículo escolar e o investimento em discussões que interseccionem a categoria de análise social com os marcadores de diferenças de classe e sexualidade.

Published: December 2023

The article presents results of investigation of plasters (mono-layered, inhomogeneous and irregularly pigmented) and clays found during archaeological excavations in the Gluhite Kamani Site in the Eastern Rhodopes, Bulgaria. The applicated methods in this study are: optical, physical and experimental. According to the established natural mineral and rock inclusions, the studied plasters show a similar composition. The samples of clay from the central sector of the archaeological site are with different physical features and similar composition. The conducted experimental firing of these clays and the established composition of the plasters, allows us to assume that the same was used for construction of buildings and for plaster, uncovered in parts of the archeological site.
Impact of climate change on the extreme weather hazards and natural disasters in Bulgaria
Authors: Nikolova Mariyana
Published: December 2023

The question of whether the climate of Bulgaria is changing and in what direction is not yet fully understood and this gives rise to various hypotheses and analyzes, which are often a reason for heated discussions between scientists with different expertise. However, there is agreement between the scientists that the increase in the frequency and intensity of meteorological and climate extremes and the natural disasters provoked by them are related to climate change. The possible effects of climate and meteorological extreems on the risk of adverse events and natural disasters in Bulgaria have been studied by different authors for different periods of observation. There are also many open access data that we have used for analysis purposes in this paper. The article aims to interpret the results of various studies on the changes in the behavior of major climatic and meteorological elements and extremes in Bulgaria in recent decades in the context of existing scenarios and indicators of climate change in the latter. The results show that there are already changes in the indicators for the territory of our country and that Bulgaria will be significantly affected by the global warming to the end of this century. This impact will in most cases be unfavorable both for the country’s economy and for the people’s health and the state of ecosystems, and will contribute to increasing the risk of natural disasters.
