Fecal gelatinase does not predict mortality in patients with alcohol-associated hepatitis
Authors: Yang Yongqiang , Hartmann Phillipp , Schnabl Bernd
Published: October 2024

Alcohol-associated liver disease is highly prevalent worldwide, with alcohol-associated hepatitis as a severe form characterized by substantial morbidity, mortality, and economic burden. Gut bacterial dysbiosis has been linked to progression of alcohol-associated hepatitis. Fecal cytolysin secreted by the pathobiont Enterococcus faecalis (E. faecalis) is associated with increased mortality in patients with alcohol-associated hepatitis. Although gelatinase is considered a virulence factor in E. faecalis, its prevalence and impact on alcohol-associated hepatitis patient outcomes remains unclear. In this study, 20 out of 65 (30.8%) patients with alcohol-associated hepatitis tested positive for gelatinase in their stool. There were no significant differences in 30-day and 90-day mortality between gelatinase-positive and gelatinase-negative patients (p=0.97 and p=0.48, respectively). Fecal gelatinase had a low discriminative ability for 30-day mortality (area under the curve [AUC] 0.50 vs fibrosis-4 Index (FIB-4) 0.75) and 90-day mortality compared with other established liver disease markers (AUC 0.57 vs FIB-4 0.79 or ‘age, serum bilirubin, INR, and serum creatinine’ (ABIC) score 0.78). Furthermore, fecal gelatinase was not an important feature for 30-day or 90-day mortality per random forest analysis. Finally, gelatinase-positive patients with alcohol-associated hepatitis did not exhibit more severe liver disease compared with gelatinase-negative patients. In conclusion, fecal gelatinase does not predict mortality or disease severity in patients with alcohol-associated hepatitis from our cohort.

Oversight of Government Spending on Combating Covid-19
Authors: Pires Victor Marcel Pereira , Lima Rafael Sousa , Souza Paulo Vitor Souza de
Published: October 2024

The research aims to analyze the federal government's expenditures in 2020 and 2021 related to combating the COVID-19 pandemic in search of fraud indicators. This period was characterized by a sudden increase in public spending, accompanied by less stringent procurement processes. The Newcomb-Benford Law describes the frequency of leading digits in datasets and is presented as an effective tool for identifying anomalies and fraud in financial records, being widely explored in various fields, particularly in audits and accounting. A comparison was made between the observed and expected frequencies for the first, second, and first two digits of the committed values, segregated by year or procurement method. The analysis was conducted through graphs and statistical tests to verify the adherence of distributions to the Newcomb-Benford Law. Commitments made in 2020 showed better adherence than those in 2021, suggesting a higher probability of manipulations or fraud in the second year of the pandemic. Additionally, expenditures resulting from bidding processes were more compliant when compared to non-bid expenditures, confirming the perception that there is a higher likelihood of manipulation or fraud in non-bid spending. The research reveals indications that can be interpreted as warnings for oversight and control bodies, with the proposed approach serving as a mechanism for auditing government expenditures, assisting in the selection of samples that require detailed analysis by auditors and investigator.
Corporate use of the X social media platform and analyst forecasting
Authors: Giordani Mikaéli da Silva , Klann Roberto Carlos
Published: October 2024

This study aimed to investigate whether the corporate use of X (formerly Twitter) for disseminating financial information, as well as likes, comments, and retweets related to this information, can improve analysts' forecasting accuracy. The dissemination of information on X signals additional evidence for stakeholders in the organization, such as analysts. Multiple linear regression was employed, with robust standard errors. The analysis consisted of 2,548 observations from the period of 2013 to 2019. The results demonstrate that analysts' forecast error is maximized according to the reactions to the posts. Likes, comments, and retweets from the previous quarter influence the accuracy of analysts' forecasts in the current quarter. A possible explanation for this result may lie in the fact that companies publish excessively optimistic information. This leads to an optimistic reaction from users, consequently inducing analysts to err. Further analysis examined the interaction between profitable companies during the period and the variables from X. The results of the interaction between the variables and the companies' profits indicated that profitable companies that tweet demonstrate a greater forecast error from analysts compared to profitable companies that do not tweet. The research highlighted that social media can be an important channel for companies to disseminate financial information. Furthermore, the interaction between companies and stakeholders, or among stakeholders themselves on X, facilitates communication, information circulation, and enables feedback—factors that, together, influence stakeholders in the company, such as analysts.

Prácticas de sí en la formación de maestros. Un estado del arte sobre subjetividad política en educación
Authors: González Ulloa Elkin Orlando , Gómez Velásquez Sol Natalia (QEPD)
Published: October 2024

Este artículo es parte de los productos de investigación del estudio denominado “Prácticas de sí en la formación de maestros. Configuración de la subjetividad política en clave de educación corporal”, el cual tuvo lugar durante el dos mil veintidós (2022) con el apoyo de la Universidad de los Llanos y se enmarca en la tesis doctoral adscrita al Doctorado en Educación de la Universidad de Antioquia (Colombia). Su objetivo, aunque se centra en la generación de conocimiento acerca de los modos de formación que configuran la subjetividad política del maestro, apunta en lo fundamental a una revisión literaria basada en tres momentos (preoperatorio, heurístico y hermenéutico). Los hallazgos más relevantes del proceso de tejeduría documental permiten darcuenta de trayectorias y tendencias teórico-metodológicas alrededor de la subjetividad política y su relación con la educación como un problema de estudio que cada vez ocupa más espacio y atención en la formación de maestros.
Dispositivos didácticos como espacios de formación decolonial para estudiantes de media académica: una aproximación desde la clase de Educación Religiosa
Authors: Benjumea-Loaiza Cetty Carlos
Published: October 2024

La Educación Religiosa, históricamente ha sido concebida como un saber escolar de carácter hegemónico y alienante que ha oprimido a los jóvenes en su dimensión religiosa por lo que, este artículo describe un camino de descolonización de dicho saber a partir de los planteamientos presentados por los educandos al interior del aula. Apoyándose en la doble hermenéutica, través de la cartografía social-pedagógica, grupos focales, didactobiografías y el análisis de contenido, se configuró un dispositivo didáctico que intersecó las representaciones sociales de los educandos con los metalenguajes propios de la Educación Religiosa, el cual fue dinamizado en un centro educativo privado de carácter confesional de la ciudad de Montería. Lo anterior generó unasituación didáctica en la que se trascendieron los aprendizajes de carácter confesional, dando lugar al estudio del fenómeno religioso en sentido estricto, su relación con la espiritualidad, el diálogo interreligioso y la relación religión-sociedad. En este sentido, se evidenció que el maestro y los educandos construyeron un espacio de reconocimiento que trascendió la confesionalidad, planteando una dinámica de deconstrucción de los discursos dominantes, permitiendo la configuración de la identidad religiosa de cada uno de ellos, que a su vez posibilitó la oportunidad establecer diálogos desde la libertad religiosa y la construcción de subjetividades que cuestionaron la realidad inmediata y mediata desde los diferentes discursos que se problematizaron a través del dispositivo didáctico.
La transformation de l'expérience dans le récit médical
Authors: MERMINOD Gilles
Published: October 2024

Comment les récits transforment-ils l’expérience personnelle ? Et en quoi cette transformation contribue-t-elle à favoriser l’exercice de l’autonomie ou à la limiter ? Voilà deux questions centrales pour qui souhaite employer les récits en contexte médical. Pour y répondre, la contribution s’appuie sur les acquis de la narratologie et de l’analyse du discours, exemplifiant son propos par une étude de cas, le récit autobiographique d’une transplantation d’organes. En synthèse, les récits peuvent donner aux personnes auxquelles ils s’adressent les moyens d’exercer leur capacité de choix en matière de santé, leur suggérant des modèles d’action et de pensée. Néanmoins, la mise en récit de l’expérience peut aussi conduire à imposer certaines visions du monde et à dénier la légitimité de certaines positions, mettant en péril l’exercice même de l’autonomie. Pour éviter de tels écueils, la contribution invite à porter attention aux dynamiques relationnelles construites par les récits et propose un schéma d’évaluation en six questions soutenant la réflexion éthique.
Paradoxes de l’autonomie et de la vulnérabilité dans la prise en charge des mineurs non accompagnés
Authors: MEISEL Pierre
Published: October 2024

Autonomie et vulnérabilité constituent aujourd’hui un véritable continuum anthropologique sur lequel chaque individu peut être situé. Si jusqu’à la seconde moitié du XXe siècle ce continuum était disjonctif, c’est-à-dire situant clairement l’individu sur un des deux pôles, il semble aujourd’hui de plus en plus conjonctif : l’individu autonome recèle dorénavant une part de vulnérabilité et symétriquement, l’individu vulnérable possède un capacitaire qui peut le mener vers l’autonomie. Mais loin d’une société du care, l’étude d’un service d’accueil de mineurs non accompagnés révèle que tant l’autonomie que la vulnérabilité semblent refusées à ces jeunes exilés. Si ce constat pourrait alors remettre en cause l’hypothèse d’une nouvelle donne anthropologique, il semble au contraire qu’il puisse être la traduction d’une des formes possibles de ce nouveau régime conjonctif. Etant devenu impossible de n’être situé que du côté de la vulnérabilité ou de celui de l’autonomie, l’individu serait ainsi sans cesse renvoyé d’un pôle à l’autre, nécessairement dans un entre-deux.
Crise de l’homme et quête du sens
Authors: DIENG Ngor
Published: October 2024

Chronologiquement, Les Lumières d’abord, la mondialisation ensuite, avaient promis un monde plus rayonnant et installé dans la « paix perpétuelle » et le progrès réel, à tous les niveaux de la vie. Que reste-t-il de cette promesse ? Notre humanité est traversée par des crises, à la fois ontologique, axiologique et intellectuelle. Les sciences humaines, sous le coup de la crise, cherchent une réponse à la quête du sens de notre existence. En philosophie autant qu’en sociologie, le sens de l’humain est en question. Après la faillite de la pensée occidentale moderne, dans sa tentative de solution, la pensée africaine est-elle en mesure de ré-enchanter le monde ? Les cosmogonies bambara et peulh développent, en ce sens, des conceptions de la personne où l’homme demeure un « être total ». Celui-ci doit prendre en charge toutes les dimensions de son être pour espérer ainsi trouver l’équilibre puis normaliser ses relations à autrui et à son environnement.

Argumentação erística nas interações digitais
Authors: De Azevedo Isabel Cristina Michelan , Gonçalves-Segundo Paulo Roberto , Piris Eduardo Lopes
Published: October 2024

Este artigo visa a analisar dois tipos de interações argumentativas erísticas realizadas na rede social YouTube da CNN Brasil: a interação entre debatedores e mediadores do Debate 360 e a interação entre os comentários dos usuários da rede social sobre o mesmo debate. Apoia-se nos aportes teóricos de Plantin (2008) sobre a perspectiva interacional da argumentação, de Amossy (2018) sobre a argumentação polêmica, de Walton (1998) sobre o diálogo erístico e de Culpeper (2011) e Blitvich (2010) sobre a impolidez na interação. O corpus constitui-se de doze intervenções argumentativas do debate e uma cadeia de nove comentários, caracterizados pelo diálogo de teor erístico. A análise do corpus focaliza (1) a interação entre dois especialistas sobre o tema controverso do uso da hidroxicloroquina em pacientes de covid-19, mediados por dois jornalistas e (2) a interação entre usuários da rede em reação à argumentação dos médicos. O estudo demarca quais características da modalidade polêmica estão presentes nos dois tipos de interação, especifica as marcas do diálogo erístico e indica como os atos de impolidez associam-se à argumentação. Os resultados permitem compreender o funcionamento da interação argumentativa erística no ambiente digital e como o processo de formação de bolhas ideológicas potencializa as oportunidades de confronto de posição.
Exploring Science Teachers' Use of Personification Stories
Authors:   , Kadhim Emily , Kiosoglous Cameron
Published: October 2024

The purpose of this convergent parallel mixed methods study was to explore the use of personification stories as an instructional strategy by high school science teachers to inform the creation of a new model for personification storytelling to support science instruction. There are a limited number of models available to science instructors to teach science using personification stories. However, there are multiple highly cited instructional models that outline how science teachers should teach using analogies. This study explained that personification stories are narrative analogies, demonstrating the importance of gleaning from the analogy literature what can best be applied to the instructional strategy of personification storytelling. The research questions that guided the study were: 1. Which instructional strategies do high school science teachers use to help students effectively learn scientific concepts? Is there a significant difference between science teachers who have been using personification storytelling as a strategy for teaching science and which science subject-matter is their primary area of expertise? 2. What are high school science teachers' perspectives on the use of personification stories in the classroom? Does the perception that personification storytelling is a good science teaching strategy significantly differ by sex assigned at birth of the science teacher? Does science teacher interest in trying to use personification storytelling to teach abstract scientific concepts significantly differ by the type of school where the teacher is employed? 3. What factors support the design and implementation of personification storytelling as an instructional strategy in the high school science classroom? To answer these questions, 99 current high school science teachers who had a minimum of one year of U.S. high school science teaching experience completed a Qualtrics online questionnaire entitled High School Science Teachers' Awareness, Use, and Perspectives on Personification Storytelling (TAUPPS). The study results revealed data previously unknown in the literature regarding high school science teachers' perspectives on personification stories as well as insight that can inform the creation of a new model for personification storytelling.

Panorama empresarial y oportunidades para el ecosistema emprendedor en la amazonía colombiana
Authors: Echeverry Isabela , Giles Álvarez Laura , Stagno Daniel , Zuluaga Sergio
Published: October 2024

La Región Amazónica Colombiana (RAC) es una zona del país crucial para el ecosistema, sociedad y economía del país. Pese a esto, la región generó apenas 1% del PIB de Colombia en 2022. Esto se debe, en parte, a los desafíos que enfrenta el ecosistema empresarial de la región. Este estudio caracteriza el ecosistema emprendedor del RAC, analiza las oportunidades de desarrollo y propone acciones de política pública y diálogo. Promover el desarrollo inclusivo y sostenible requiere fortalecer el ecosistema emprendedor, mejorar las habilidades, el acceso a los mercados y la competitividad. El diálogo entre los sectores público y privado y las medidas de política serán, por tanto, esenciales para crear un entorno propicio para el crecimiento y el desarrollo.
Atención a la conflictividad minera en América Latina y el Caribe: una guía para la acción
Authors: Irazábal Briceño Irene , Nunes da Cunha Natascha
Published: October 2024

La minería es un pilar fundamental para el desarrollo económico de América Latina y el Caribe, especialmente en el contexto de la transición energética global, que ha incrementado la demanda de minerales clave como cobre, litio, niquel, hierro y bauxita, entre otros. Al mismo tiempo, la minería ha sido históricamente una fuente de conflictos sociales que involucran a múltiples actores. Para que la minería contribuya plenamente al desarrollo sostenible debe ser moderna, innovadora, inclusiva y responsable tanto social como ambientalmente. A pesar de los numerosos e importantes esfuerzos por implementar estándares sociales y ambientales que den cuenta de los desafios y las oportunidades que enfrenta la actividad, las tensiones y resistencias hacia la minería persisten. En ese sentido, la gestión de la conflictividad asociada a la minería es crucial para asegurar que la extracción de estos recursos minerales beneficie tanto a las comunidades locales como a los objetivos globales de sostenibilidad. Este documento analiza las dinámicas complejas de los conflictos mineros, los costos asociados para actores privados y públicos y la necesidad de estrategias proactivas, basada en un abordaje sistémico, para transformar los conflictos en oportunidades de desarrollo. Además ofrece una guía para que los responsables de políticas integren la gestión de la conflictividad en la planificación de largo plazo en las regiones ricas en recursos minerales.
A New Method for Feeding Laboratory-Reared Aedes aegypti (Diptera: Culicidae) Adult Females1
Authors: Morales-Hernández Filemón , Rodríguez-Maciel J. Concepción , Pardo-Melgarejo Saul , Ramírez-Becerril Valeria , Meraz-Maldonado Nora , Aguilar-Garzón Bismarck
Published: October 2024

The mosquito Aedes aegypti (L.) (Diptera: Culicidae) transmits arboviruses including the causative agent for yellow fever and threatens human health in tropical and subtropical areas. To reduce the incidence of infection, a variety of tactics is being developed to keep the population density of this vector mosquito as low as possible. Laboratory research directed to this end requires maintaining laboratory colonies of the insect, which, in this case, requires providing immobilized live animals to A. aegypti adult females for a source of blood for production of viable eggs. Using live animals for this procedure is costly, time consuming, and requires rearing mammalian species in the laboratoy. This study evaluated the impact of supplying the adult females with blood from a domestic pig (Sus scrofa domestica L.) mixed with an anticoagulant (7 ml of heparin per liter of blood) on the oviposition rate of A. aegypti. Feeding A. aegypti females with pig blood obtained from a slaughter facility and mixed with heparin produced more eggs (6,994 ± 168) than those allowed to feed on a living hamster as a source of blood (5,483 ± 171). Thus, this methodology is more efficient and economical than the current use of live animals to feed females of A. aegypti.
El ciego de nacimiento: un análisis narrativo de Jn 9
Authors: Vanegas Gerardo , Ramírez Daza Andrea , Rodríguez Diaz Dina Elizabeth
Published: October 2024

Los autores estudian a partir del análisis narrativo Jn 9, un texto que ha sido poco tratado en su totalidad como historia narrada. El artículo está dividido en tres secciones. La primera, más extensa, se ocupa del estudio narrativo del texto. El estudio ofrece una visión amplia de la narrativa, una lectura sincrónica del texto tal como ha llegado hasta nosotros, una lectura que sugiere algunas ideas que pueden pasar desapercibidas para el lector que considera el texto basándose en métodos diacrónicos legítimos. La segunda sección complementa el estudio narrativo con una aproximación teológica de la historia, y la última sección es una lectura hermenéutica que muestra cómo grupos de reclusos relacionan el texto con su situación personal.

Published: October 2024

En la medicina tradicional mexicana, diferentes hierbas son utilizadas por su potencial efecto antidiabético. Este estudio tuvo como objetivo investigar los mecanismos subyacentes a los efectos antihiperglucémicos de I. sonorae, C. limetta y B. media. Los extractos acuosos de estas hierbas demostraron una consistente reducción en los niveles postprandiales de glucosa en sangre durante una prueba de tolerancia oral al almidón. Destacando que, los extractos de B. media e I. sonorae mostraron un efecto inhibitorio significativo in vitro contra la actividad de alfa-amilasa (20.5 y 25.4 %, respectivamente), mientras que B. media aumentó 4.0 veces la internalización de glucosa en adipocitos, lo cual fue relacionado con la sobreexpresión de genes claves involucrados en la cascada de señalización de la insulina incluyendo Glut4, Irs1 y Pi3k (2.9, 2.6 y 3.2 veces, respectivamente). Además, el análisis multivariado resaltó que el ácido hidroxibenzoico hexódio y el ácido feruloilquínico fueron asociado con la actividad inhibitoria de alfa-amilasa, mientras que 17 polifenoles fueron asociados con la actividad mimética a la insulina. Estos hallazgos proponen la aplicación potencial de estas hierbas en el desarrollo de bebidas funcionales con prometedoras propiedades antidiabéticas.

Published: October 2024

The article examines the effectiveness of the gradient descent and Newton methods for optimizing the parameters of  ensembles of complex signals. Algorithms have been developed and implemented that increase the accuracy of setting  parameters and ensure reasonable optimization of spectral, temporal and statistical characteristics of signals. The effectiveness of the application of the methods was confirmed experimentally on the example of reducing the error and  increasing the level of immunity. The obtained results substantiate the improvement of the parameters of complex signals,  which proves the efficiency of use for wireless telecommunication systems in order to ensure stable and reliable operation in  conditions of dynamic changes in the environment and a high level of interference.The article compares the mathematical methods of optimization, namely the gradient method and Newton's method,  proposes mathematical models and constructs algorithms that empirically prove the effectiveness of the application of the  studied mathematical methods in the specified scientific area - for optimizing the parameters of ensembles of complex signals. Scientific works [1-6, 9, 12] present algorithms based on the gradient method and Newton's method, but they do not consider  in detail the comparative analysis of the effectiveness of these methods for optimizing the parameters of ensembles of  complex signals for implementation in various scientific and practical tasks. The effectiveness of the algorithms proposed in the article was confirmed experimentally, which made it possible to reduce  the error and improve the characteristics of ensembles of complex signals.As a result of the experiments using the methods of gradient descent and Newton, a significant reduction of the error and an improvement of the stability of the signals were achieved. Newton's method reduced the error from 0.1 to 0.0027, justifying  the high accuracy of setting the signal  parameters. The gradient descent method provided a stable reduction of the gradient  norm from 12.75 to less than 1.23, effectively reducing the interference level, i.e. increasing the interference immunity.
“Um depósito de agonia”: assistência aos tuberculosos na Santa Casa de Misericórdia da Paraíba (1906-1942)
Authors: Araújo Rafael Nóbrega , Miranda Carlos Alberto Cunha
Published: October 2024

O presente artigo analisa as condições da assistência médica prestada aos tuberculosos pela Santa Casa de Misericórdia da Paraíba (SCMPB), mais especificamente no Hospital Sant’Anna, que durante a primeira metade do século XX recolheu os tísicos indigentes que procuravam aquela instituição. Embora um dos compromissos da Irmandade da Misericórdia fosse o de “tratar os doentes”, os Relatórios de Provedoria alegavam que assistir os tuberculosos não era obrigação da Pia Instituição. Argumentamos que essa recusa se dava em virtude de alegadas questões econômicas por parte da SCMPB, uma vez que a tuberculose por ser uma doença crônica e, para a época, incurável, e pela maioria dos enfermos serem desvalidos e indigentes, sua manutenção concorria para um custo supostamente muito elevado para a Santa Casa. A análise da documentação compulsada apontou para a absoluta precariedade das condições higiênicas em que esses sujeitos históricos – os tuberculosos pobres – eram assistidos pela Santa Casa.
Catolicismo de massas e política no Brasil: 1930-1934
Authors: Aquino Maurício de
Published: October 2024

Este artigo apresenta uma análise da construção do catolicismo de massas e de suas repercussões políticas no Brasil, de 1930 a 1934, desde uma perspectiva da “nova história política”. O trabalho de interpretação e reconstrução histórica desse período acerca das relações entre religião e política foi orientado pela tese segundo a qual a Igreja Católica reinventou o seu lugar político na ordem republicana ao mesmo tempo em que o Estado republicano em crise, nos primeiros anos do governo de Getúlio Vargas, buscou na aproximação com a instituição eclesiástica uma de suas bases de legitimação, além de um repertório de estratégias de mobilização controlada do povo, que, por outro lado, implicou na incorporação de proposições católicas no texto constitucional de 1934.
Hematobiochemical Changes, Immunological Response and Immune Gene Expression in Nile Tilapia (Oreochrom niloticus) Experimentally Infected with Shewanella putrefaciens
Authors: Philominal P. , Uma A. , Ahilan B. , Jayakumar N.
Published: October 2024

Background: In this work, hematobiochemical changes, immunological responses, and histopathological changes in Nile tilapia (Oreochromis niloticus) experimentally infected with Shewanella putrefaciens were studied. Methods: O. niloticus was experimentally infected with S. putrefaciens (4SK/SRLFDA/19) at a concentration of 1.508×106CFU/ml per fish. Gross symptoms, namely hemorrhage on the body surface, skin discoloration, slow or nervous behavior, shallow necrotizing ulcers on the skin, fin erosions and abdominal distension were observed 5 to 6 days after infection. Fish were anesthetized and blood samples were collected at 0, 2, 4, 7, 10, 14, 20 and 27 days after the experimental infection to assess the hematobiochemical and immunological responses. For haematobiochemical responses, tests that included hemoglobin (Hb), leukocyte count (Lc), erythrocyte, hematocrite (Ht), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), cholesterol (CHO), glucose (GLU) and triglyceride were assessed. Result: Values of hematocrit, hemoglobin, albumin, globulin, erythrocyte, MCHC, cholesterol and triglyceride were significantly (p less than 0.05) decreased. Lc, MCV, MCH, and glucose values were significantly (p less than 0.05) increased. Respiratory burst activity (RBA) and serum total protein values were significantly (p less than 0.05) decreased. Relative expression of immune gene toll like receptor 4 (TLR4), stress genes heat shock proteins 70, 90 (HSP70, HSP90), oxidative stress gene glutathione S-transferases (GST) and inflammatory gene interleukin 6 (IL6) was significantly higher in experimentally infected fishes compared to control.

L’état de dégradation des forêts est une préoccupation mondiale particulièrement pour l’Afrique. De ce fait, plusieurs forêts classées sont de plus en plus menacées d’extinction dont les causes sont anthropiques et climatiques. L’étude a évalué la dynamique du couvert végétal et ses implications sur le stock de carbone aérien et la diversité ligneuse de la Forêt Classée de Tiogo au Burkina Faso. Une analyse d’images Landsat des années 1990, 1999, 2009 et 2019, et des données socioéconomiques et d’inventaire forestier ont été combinées dans différentes unités d’occupation des terres : savane arborée, savane arbustive, forêt galerie et cultures pluviales et territoires agroforestiers. Entre 1990 et 2019, 47 % de la superficie des savanes arborées a été perdue au profit des savanes arbustives et des cultures pluviales et territoires agroforestiers. Les feux de brousse, la coupe du bois et l’activité agricole constituent les principaux facteurs de dégradation. Les valeurs de la diversité ligneuse de la savane arborée (2,14 ± 0,31) et de la savane arbustive (1,92 ± 0,43) étaient plus élevées que celles des cultures pluviales et territoires agroforestiers (1,31 ± 0,62) et de la forêt galerie (0,63 ± 0,41). La forêt galerie avait le plus important potentiel de stock de carbone aérien (35,5 tC/ha), suivi de la savane arborée (7,1 tC/ha), puis de de la savane arbustive (2,5 tC/ha) et des cultures pluviales et territoires agroforestiers (1,7 tC/ha). Les changements d’unités d’occupation des terres dans la Forêt Classée de Tiogo ont induit entre 1990 et 2019, une réduction de 41 % du potentiel du stock de carbone aérien. Il en ressort le besoin de promouvoir des alternatives pour les moyens de subsistance et l’énergie pour les ménages, et le renforcement des initiatives de sensibilisation.

This paper presents an experimental approach to studies of the sorption and diffusion properties of wood. Five timber species - three African tropical hardwoods, Padauk, Okoume and Iroko, and two temperate softwoods, Silver fir and Douglas fir - were studied in adsorption mode. Specimens with 10- and 20-mm longitudinal (L) and transverse (RT) thickness were waterproofed on their sides to force diffusion in those directions. After kiln drying the specimens were hung with nylon wires under cover in a home-made box in which salt solutions provided constant relative humidity (RH), and conditioned at 43, 55, 75, 84 and 97% RH in successive steps. Temperature was maintained between 20 and 24°C. During the equilibration steps the samples were periodically weighed without altering the environmental conditions imposed, by hanging the nylon wire to a spring gauge through a small hole in the box cover. The sorption isotherm properties and diffusion parameters were obtained using an inverse method based on optimization of a 1D finite difference model. The parameters obtained show a decreasing correlation between diffusion coefficient and density, as observed by several authors in the literature. They also illustrate the impact of extractives on the sorption isotherm parameters. These results show that tropical species with high density or many extractives behave very differently to European softwoods, which impedes the application of Eurocode 5 equilibrium standards for these species.

Economic Relations of Russia with “Unfriendly” and “Friendly” Countries in 1995–2020: Analysis of OECD Intercountry Input–Output Tables
Authors: Parkhimenka Ul .
Published: October 2024

The paper analyzes the dynamics of Russia’s structural economic relations with countries of the “unfriendly” and “friendly” (including “neutral”) spectrum in 1995–2020 according to data from intercountry input-output tables prepared by the OECD in 2023. The analysis focuses purely on “input” connections that involve the supply of imported intermediate production goods and final investment goods necessary for the production process at Russian enterprises. It is shown that import intensity of Russian final goods was not very high across industries (the remarkable exclusion is production of motor vehicles, trailers and semi-trailers), though input-output tables do not allow us to understand the quality and criticality of imports of industrial goods. In addition, the non-stop growth in the share of “friendly” countries is absolutely obvious. However, despite the steady decline in imports (by value added) from “unfriendly” countries in relation to imports from “friendly” countries, by 2021 the first category continued to remain prevalent in many cases, especially in machine building. The steady increase in the share of added value of “friendly” countries in the output of Russian products is apparently the result of such world processes as globalization, the rapid growth of the Chinese economy and other large developing countries, as well as the deindustrialization of Western economies. In the case of investment (capital) goods, for which Russia’s share was initially quite small, it seems that not only the global factors discussed above were at work, but also some targeted efforts of government at import substitution. It seems obvious that Russia currently faces a problem of restructuring its external economic connections and must adapt to changing global processes, maintaining a constructive approach to participation in the cross-country division of the production process, and taking into account geopolitical realities, develop new models of cooperation and integration.
“Green” Deal of Biden Administration: Ambitions and Realities
Authors: Dmitriev S.
Published: October 2024

The ambitious “green” industrial policy program promoted by the Biden administration is designed to consolidate the US claims to its leading role in shaping the global climate change agenda. The package of legislative acts approved by the White House provides for unprecedented allocations to address priorities for decarbonizing the American economy. Pumping up targeted manufacturing industries with federal subsidies and tax incentives has generally had a positive impact on economic growth, employment, labor productivity and innovation activity. After the adoption of the Inflation Reduction Act of 2022 (IRA), the process of transforming alternative energy into the fastest growing and relatively affordable source of electricity attractive for private investment accelerated. Large-scale investments of public and private funds in renewable energy sources, electric transport and batteries have stimulated the use of national resources. At the same time, the task set by the White House to achieve sole global leadership and weaken the dependence of national industry on supplies of raw materials, components and finished products from “unfriendly” countries still looks elusive. The most significant obstacle to meeting Washington’s overstated ambitions in terms of increasing the chances of American companies competing with China is the continuing lag in building up the production base of “green” energy. The US dependence on supplies of the “green triad” – solar panels, lithium-ion batteries and electric vehicles remains high. Washington’s aggressive protectionist actions have failed to prevent Chinese companies from developing alternative energy sources, as well as the new energy vehicle industry (NEVs). The confrontation with China distracts the material resources of the United States from the tasks related to the implementation of the “new green deal”, creates obstacles to the scaling of “green” technologies. If the Biden administration or his successor as US president act even more aggressively, it will make it more difficult to achieve Washington’s climate goals, may involve some US allies in a “subsidy war” and may even serve as a trigger for a new escalation of international tensions.
Conflict in Ukraine and Strategic Transformation of U.S. Arctic Policy: the Logic of “Historical Chance”
Authors: Magomedov A. , Shaparov A.
Published: October 2024

The article explores nuances of strategic transformation of the American Arctic policy after the beginning of the Russian-Ukrainian conflict. Russia’s Special military operation (SMO) in Ukraine has taken competition in the Arctic region to a new level. The paper introduces a new term “post-February” Arctic to describe the dramatic changes in the polar region after the beginning of the Ukrainian events on February 24, 2022. It shows that these events were almost unanimously perceived by Western analysts and public politicians as a “moment of strategic opportunity” to revise the international political situation in the Far North. The Russian-Ukrainian conflict critically changed the U.S. Arctic policy. The conceptual framework, within which the problems of “post-February” American polar policy are investigated, is the “offshore balancing” theory. The launch of the Russian SMO in Ukraine has led to strengthening the anti-Russian orientation of the U.S. Arctic policy. Facing a long military confrontation, Washington is trying to increase pressure in such areas critical to Russia as the Far North. However, the “post-February” U.S. Arctic policy is not so much the realization of political maximalism, but rather a reanimation and adjustment of Washington’s ambitions in accordance with the opportunities that emerged after February 24, 2022. The authors prove that despite loud calls to punish Russia for starting the Special military operation in Ukraine, the American response in this direction is restrained. The anti-Russian Arctic initiatives by various American public policy actors have a delayed rather than urgent effect. A quite moderate polar policy of the United States is explained by the fact that Washington is well aware of the limits of its capabilities in the Arctic. Its behavior throughout the current Russian-Ukrainian conflict illustrates the essence of the “offshore balancing” policy like nothing else.
