Effect of Excessive Environmental Heat Load on Digestibility, Energy Balance, and Urea Recycling in the Mediterranean (Member) Goat
Authors: Mualem Raed , Cohen Coral , Farraj Rania Hussein , abuelheija Aya , Shance Shir
Published: November 2023

This study investigates the energy and nitrogen economy of the Mediterranean goat across diverse environmental conditions, emphasizing the influence of heat stress and shelter on animal productivity. Environmental factors such as water availability, food quality, and heat stress affect the animal's capacity to convert indigestible plant components into digestible food and sustain energy balance. In particular, heat stress causes a significant decrease in the goat's food by 27.49% and by 34.85% in alfalfa hay and wheat straw respectively, leading to a loss of body mass, even when offered high-quality food such as alfalfa hay. However, when sheltered from direct sunlight, the goat can maintain an energy balance on any diet, a significant decrease in body mass was recorded, with a reduction of 10.59% for alfalfa hay and 17.79 ± 3.0% for wheat straw. Heat stress also impairs the goat's ability to maintain a balanced nitrogen economy, reducing nitrogen loss through excretion during heat load conditions and high-protein food digestion. The study found that the average urea recycling rate in goats kept in a shelter was 36%, which was significantly higher than the rate observed in goats exposed to heat stress, which was only 19.6%. Moreover, the amount of recycled urea was also higher in the shelter at 91% compared to 69.9% in the reflected heat stress recorded when the goats were maintained on a diet of wheat straw. As the goat cannot reduce its metabolic rate, a negative energy balance occurs, resulting in body mass loss. The quality of food and heat stress are critical determinants of the goat's food consumption, with high heat load reducing appetite. This study concludes that sheltered conditions, providing protection from direct sunlight, are necessary to sustain productivity and maintain a stable body mass on any diet. Furthermore, maintaining a balanced nitrogen balance can be challenging for animals consuming low-protein food, particularly under suboptimal feeding conditions. The study's findings have implications for the broader issue of global warming, as rising temperatures could increase heat stress and reduce food consumption and productivity in animals, with potentially negative consequences for agriculture and food security. Therefore, protecting animals from heat stress through adequate shelter and management practices is essential to mitigate the negative impacts of global warming on animal productivity, Animal husbandry, and human livelihoods.

Introduction: An open or exposed fracture is a fracture that has communication with the external environment through a skin wound. Usually these types of severe fractures require treatment by the orthopedic and plastic surgery team to address both bone and soft tissue injuries.
Objective: to detail current information related to open fractures, description, epidemiology, evaluation, classification, treatment and complications.
Methodology: a total of 33 articles were analyzed in this review, including review and original articles, as well as clinical cases, of which 20 bibliographies were used because the other articles were not relevant to this study. The sources of information were PubMed, Google Scholar and Cochrane; the terms used to search for information in Spanish, Portuguese and English were: exposed fractures, open fractures, acute trauma, compartment syndrome, vascular injury, debridement.
Results: the general average age of onset is 45.5 years, the incidence decreases in men and increases in women with age. Automobile accidents are the most common cause of open fractures of the lower limbs, accounting for approximately 34.1% of these injuries. The highest incidence of open fractures in males is between 15 and 19 years, the highest incidence in females is between 80 and 89 years.
Conclusions: Knowledge of the management of open fractures is of vital importance, due to the fact that this type of fracture presents a high risk of infections, as well as other types of complications. The initial approach to the injured individual with an open fracture should be based on the principles of Advanced Trauma Life Support (ATLS). Clinical and imaging evaluation is important in this type of fracture, as well as recognizing the value of the classification systems that play a critical role when treating surgically. Irrigation and debridement remain the gold standards for proper wound management. The most important point in the treatment of an open fracture is proper lavage and debridement.
KEY WORDS: trauma, open fractures, bone exposure, treatment.

Authors: Medina López José Rubén
Published: November 2023

La Reserva Natural Laguna de Tiscapa, se ubica en el centro de la ciudad de Managua, a dos kilómetros de la costa del Lago Xolotlán. Este cuerpo de agua ha sido impactado principalmente por acciones antrópicas que iniciaron en 1980 con el ingreso de agua residual doméstica y residuos sólidos (García Espinoza, 2020). Este estudio determinó el estado trófico de la laguna Tiscapa con base en la transparencia, clorofila-a y el fósforo total bajo las metodologías del Índice de Estado Trófico de Carlson (TSI) modificado por Aizaki y el modelo del Comité de Eutrofización de Cooperación Económica y Desarrollo (OCDE) utilizando muestreos de calidad de agua correspondientes a los meses de abril, junio, agosto, octubre y diciembre de 2022. Se simuló el estado futuro de la laguna en 30 años utilizando las ecuaciones de Vollenweider con el índice OCDE permitiendo ver el comportamiento de fósforo total y clorofila-a. Como resultado se obtuvo que la laguna se encuentra en un estado hipereutrófico - eutrófico, lo que se traduce en una alta presencia de nutrientes que afecta el oxígeno disponible en la laguna y la proliferación de algas que afectan la calidad el agua. En la simulación con aportes continuos y no continuos, la laguna se mantiene en un estado hipereutrófico. La simulación del escenario ideal con condiciones naturales reflejó un estado oligotrófico-ultra-oligotrófico. El estudio concluye la necesidad urgente de abordar el exceso de nutrientes y tomar medidas para restaurar y preservar la calidad de este importante recurso hídrico de Nicaragua.
Using sustainability indicators for analysis of sustainable consumption and production in the food supply chain
Authors: Senyk Yurii
Published: November 2023

Delivery of food products is one of the critical points in the manufacturing of products, especially for perishable products. In addition, it is necessary to consider the delivery schedule and additional environmental load due to the need to maintain the storage temperature conditions. It has been proven that the main factors of sustainability related to local products are determined by the desire of consumers to support the local producer, the sale of higher-quality products of local production, and the efficiency of logistics management and sale of goods. Methods to analyze the sustainability of food product transportation are considered. It is emphasized that very few studies have been conducted on analyzing the logistics of the delivery of dairy raw materials and products in countries with a weak economy, especially for enterprises of local importance whose vehicle fleet is represented by outdated equipment. That is why the study of the sustainability of logistics delivery chains was conducted based on the data of two dairy enterprises. The work presents in mathematical terms an integrated model for calculating the sustainability of logistics chains, which consists of four groups of criteria: resources, climate, economic efficiency, and impact on society. The company was evaluated according to the specified criteria by a group of independent experts in dairy technology using the Delphi method to ensure the objectivity of the obtained data. The calculation of fuel costs and CO2 emissions into the atmosphere per kilogram of food products in the transportation logistics chain was carried out. This approach will ensure the objectivity of assessing the negative impact on the environment because of the use of petroleum products, the increase of greenhouse gases, and air pollution in general. The concepts of "local food" and "food miles" are tools of the protectionist policy of restoring local agriculture and alternative sources of food production. The results obtained in the work confirm the need to use individual criteria in LCA for an objective assessment of the sustainability of logistics transportation and its impact on the environment.
Keywords: "food mile", food products, environment, sustainability indicators, temperature regimes.

Published: November 2023

The aquaculture sector continues to be an essential source of food, revenue, nutrition, and a means of subsistence for numerous people globally. Intensive aquaculture in a confined region induces environmental stress in farmed fish, which indirectly increases their vulnerability to many diseases. Aeromonas hydrophila, Pseudomonas aeruginosa, and Vibrio harveyi are the causative bacterial pathogens for septicemia, the most prevalent and commonly seen illness. Disease outbreaks result in a rise in mortality or a decrease in the quality of the meat, consequently inflicting substantial economic losses to carp production. In contrast, the continual use of antibiotics for infection management has contributed to the proliferation of drug-resistant bacteria in aquatic environments. In this context, marine actinobacteria are emerging as possible sources of new secondary metabolites to combat the problem. Actinobacteria are undoubtedly the most prolific producers of secondary metabolites, and they comprise several commercially and biotechnologically significant species. In this investigation, marine actinobacteria were isolated and evaluated for their antibacterial effectiveness against septicemia pathogens. Effective strains were identified as Nocardiopsis sp., Streptomyces sp., and Pseudonocardia sp. Candidate strains culture filtrates were treated with acetone to precipitate complete proteins. The antibacterial and anti-quorum sensing properties of the crude protein against A. hydrophila MTCC 1739 and P. aeruginosa MTCC 9425 were also examined using the agar well diffusion method. In addition, in vivo investigations of the low molecular weight fraction on Labeorohita demonstrated the fraction's efficacy in reducing septicemia infection. After the 8th day of bathing, fish were found to have recovered.

Published: November 2023

Performance of manufacturing firms has been highly influenced by macro environmental factors ranging from political instability and socio-economic factors. As a result, knowledge management has increasingly become crucial in reducing the impact on both internal and external factors. The study aimed to determine the relationship between knowledge management capacity building and productivity of sugar companies in Kenya. The study assessed the moderating effect of transformational leadership on the relationship between capacity building and the productivity of sugar companies. This was anchored on the theory of change which explains the need for knowledge management in managing business dynamic external environment. The study adopted a positivist research philosophy and correlational research designs. Questionnaires were administered in a census survey to 218 managers working in 8 sugar companies in Kenya. Mean and standard deviation was utilized with frequencies as descriptive statistics. A simple regression was adopted to establish the relationship between knowledge management capacity building and productivity of firms. The finding revealed that the sugar firms shared knowledge, however, there was need to improve knowledge management system, knowledge retrieval and knowledge acquisition. There was significant relationship between innovative capacity building and productivity. The study concludes that there was statistically significant relationship between knowledge management capacity building and organization productivity. It is recommended that there is a need to improve the knowledge management system and policies to enhance productivity of organizations

Through this community service activity, training will be given on procedures for developing brown sugar products and the online marketing process through e-commerce. Product development is carried out by providing training to the public about processing liquid brown sugar so that the brown sugar they market is not only in simple form, but the product can be further developed and will have an impact on higher selling value (economic value). With a high selling value, it will have an impact on brown sugar sales revenue which will increase. Furthermore, after providing training on how to manage liquid brown sugar until it reaches the stage of packaging the product properly so that the liquid brown sugar is ready to be marketed. After product development, they will also be taught about online marketing strategies through various social media applications such as Facebook and Instagram. Apart from that, there is also online marketing in one of the number one online shop applications in Indonesia, namely the Shopee application. In this way, it is hoped that the brown sugar products they produce will not only be marketed on a local scale but will be able to compete on the national scale market.

Published: November 2023

Measuring resistances at the nanoscale has attracted recent attention for developing microelectronic components, memory devices, molecular electronics, and two-dimensional materials. Despite the decisive contribution of scanning probe microscopy in imaging resistance and current variations, measurements have remained restricted to qualitative comparisons. Reference resistance calibration samples are key to advancing the research-to-manufacturing process of nanoscale devices and materials through calibrated, reliable, and comparable measurements. No such calibration reference samples have been proposed so far. In this work, we demonstrate the development of a multi-resistance reference sample for calibrating resistance measurements in conductive probe atomic force microscopy (C-AFM) covering the range from 100 Ω to 100 GΩ. We present a comprehensive protocol for in situ calibration of the whole measurement circuit encompassing the tip, the current sensing device, and the system controller. Furthermore, we show that our developed resistance reference enables the calibration of C-AFM with a combined relative uncertainty (given at one standard deviation) lower than 2.5% over an extended range from 10 kΩ to 100 GΩ and lower than 1% for a reduced range from 1 MΩ to 50 GΩ. Our findings break through the long-standing bottleneck in C-AFM measurements, providing a universal means for adopting calibrated resistance measurements at the nanoscale in the industrial and academic research and development sectors.

Authors: Pérez Hernández Valetín , Hernández Guzmán Mario
Published: November 2023

La diversidad de microorganismos en el suelo es elevada y su identificación mediante el uso de técnicas tradicionales de cultivo resulta inadecuada y limitada para un elevado porcentaje de los mismos. En la actualidad se cuentan con tecnologías de secuenciamiento masivo del ADN que ha permitido, junto a otras técnicas y herramientas, incluyendo la bioinfomática, la identificación de microrganismos sin necesidad del uso de medios de cultivos. Sin embargo, la secuenciación masiva ha generado enormes cantidades de información que requiere ser analizada y por ende demanda un esfuerzo computacional considerable. Existen diversos programas bioinformáticos, basados en uno o varios lenguajes de programación, para el análisis molecular in silico de secuencias de ADN, e.g., MOTHUR, QIIME1, DADA2 y QIIME2. De estos, QIIME2, por sus siglas en inglés “Quantitative insights into microbial ecology”, es una herramienta frecuentemente empleada para el analisis datos de secuenciamiento de marcadores moleculares o genes funcionales, e.g., 16S rRNA, 18S rRNA, ITS, COI, entre otros. Dada la importancia de éstas, y de la necesidad de acceso a este conocimiento en lenguaje español, en esta revisión se describe y detalla el flujo de trabajo para el análisis de secuencias del gen 16S rRNA provenientes de muestras ambientales empleando QIIME2.

Sanat, bir duygu veya düşüncenin en güzel en estetik haliyle görsel ve işitsel bir maddede vücut bulmuş halidir. Aslında sanatın ne olduğuna dair tarih öncesi çağlardan günümüze kadar çeşitli cevaplar aranmıştır. İlk insanların mağara duvarlarına çizdikleri şekil ve sembollerde onların iç dünyalarının birer yansıması olarak sanatın ilk izlerini taşımıştır. İnsanlığın geçirdiği evrimlerle, yaşama biçimleri, hayata bakışları, sanat biçimlerini ve sanata olan bakışlarını da değiştirirken her dönemde ve her toplumda, farklı görünümlerde daima ortaya çıkmıştır. Aslında insanlar, yaşamlarından bir kesitini veya günlük bir olayı aktarırken bir şekilde başka insanlarla da iletişim kurmuşlardır. Bu sayede, duygu ve düşüncelerini yaptıklarını başkalarına aktarırken, oluşturdukları obje resim ve semboller de bir köprü vazifesi görmüş her çalışma da zaman içerisinde birer iletişim aracına dönüşmüştür. Tarihte insanın temel ihtiyaçlarını giderme çabalarıyla kendini anlatma istekleri de giderek bir estetik kimlik kazanmış ve sanatı doğurmuştur. Sonrada iletişimle yaygınlaşmış, kuşaktan kuşağa da aktarılarak günümüze kadar gelmiştir. İnsanoğlunun yaşamını zevkli kılma amacıyla çaldığı enstrümanı, çizdiği resim, sesi, sözü ile bedenin dilini estetik yetkinliğe ulaştırarak sanata dönüştürürken doğa ve kendisiyle iletişimini, etkileşimini de zenginleştirmiştir. Böylece sanat ve iletişimin, birbirini var etme sürecinde de yaşamsal bir ilişkisi (semiyotik) söz konusu olmuştur. Bu araştırma ile, ekspresyonist tarzda çalışmalar üreten sanatçı Necmettin Özlü’nün eserlerinin teknik ve estetik özellikleri bakımından incelenip değerlendirilmesi amaçlanmaktadır.

Aim: to assess the effectiveness of PAH-specific therapy, including selexipag, based on data from a comprehensive examination and assessment of oxygen transport function in patients with IPAH using Raman spectroscopy.

Materials and methods. The study was performed on fourteen (n=14) patients diagnosed with IPAH who were on combination PAH-specific therapy, including selexipag. The diagnosis was established in accordance with the algorithm proposed in the Russian guidelines for the diagnosis and treatment of PAH (2020). A comparative analysis of clinical and hemodynamic parameters, including an assessment of hemoglobin conformation using Raman spectroscopy, was performed in all participants.

Results. The use of Selexipag as part of a combined PAH-specific therapy caused significant changes in the conformation of Hb including a decrease in the probability of a “dome-shaped” heme conformation due to changes in the group vibrations of heme pyrrole groups (I1375/I1172) and stretching vibrations of vinyl groups (I1580/I1550), as well as an increase globin density.

Conclusion. The use of the prostacyclin receptor agonist selexipag as part of a combination PAH-specific therapy for patients with IPH was associated with improvement in clinical, functional and molecular parameters (taking into account the assessment of oxygen transport function and hemoglobin conformation by Raman spectroscopy).

The Dark Energy Spectroscopic Instrument (DESI) survey is a spectroscopic survey of tens of millions of galaxies at 0 < z < 3.5 covering 14,000 sq. deg. of the sky. In its first 1.1 yr of survey operations, it has observed more than 14 million galaxies and 4 million stars. We describe the processes that govern DESI’s observations of the 15,000 fields composing the survey. This includes the planning of each night’s observations in the afternoon; automatic selection of fields to observe during the night; real-time assessment of field completeness on the basis of observing conditions during each exposure; reduction, redshifting, and quality assurance of each field of targets in the morning following observation; and updates to the list of future targets to observe on the basis of these results. We also compare the performance of the survey with historical expectations and find good agreement. Simulations of the weather and of DESI observations using the real field-selection algorithm show good agreement with the actual observations. After accounting for major unplanned shutdowns, the dark time survey is progressing about 7% faster than forecast, which is good agreement given approximations made in the simulations.
Environmental Impacts on the Rest-frame UV Size and Morphology of Star-forming Galaxies at z ∼ 2
Authors: Naufal Abdurrahman , Koyama Yusei , Shimakawa Rhythm , Kodama Tadayuki
Published: November 2023

We report the measurement of rest-frame UV size and morphology of Hα-emission-selected star-forming galaxies (HAEs) in four protoclusters at z ∼ 2 (PKS 1138-262, USS 1558-003, PHz G237.0+42.5, and CC 2.2) using archival Hubble Space Telescope Advanced Camera Survey (HST/ACS) F814W data. We compare the measurement of 122 HAEs in protoclusters detected by HST/ACS to a coeval comparison field sample of 436 HAEs. We find the size distributions of protocluster and field HAEs are similar with a typical half-light radius of ∼2.5 kpc. At fixed stellar mass, there is no significant difference between HAEs in the protocluster and in the field, which is also supported by stacking analyses. This result suggests that the environment does not significantly affect the size of galaxies during the star-forming phase at this epoch. Based on the Sérsic index and nonparametric morphologies, HAE morphologies in both environments at z ∼ 2 in rest-frame UV are consistent with disk-like star-forming galaxies, although we also find 29% ± 4% HAEs showing disturbed morphologies. The fraction of disturbed galaxies is higher in the protocluster environment, with 39% ± 8% protocluster HAEs showing disturbed morphologies, compared to 26% ± 4% in the comparison field. The apparent disturbed morphologies are correlated with higher star formation activity and may be caused by either in situ giant clumps or mergers.

We present uniformly measured stellar metallicities of 463 stars in 13 Milky Way (MW) ultra-faint dwarf galaxies (UFDs; M

V
= −7.1 to −0.8) using narrowband CaHK (F395N) imaging taken with the Hubble Space Telescope. This represents the largest homogeneous set of stellar metallicities in UFDs, increasing the number of metallicities in these 13 galaxies by a factor of 5 and doubling the number of metallicities in all known MW UFDs. We provide the first well-populated MDFs for all galaxies in this sample, with 〈[Fe/H]〉 ranging from −3.0 to −2.0 dex, and σ
[Fe/H] ranging from 0.3–0.7 dex. We find a nearly constant [Fe/H]∼ −2.6 over 3 decades in luminosity (∼102–105
L
⊙), suggesting that the mass–metallicity relationship does not hold for such faint systems. We find a larger fraction (24%) of extremely metal-poor ([Fe/H]< −3) stars across our sample compared to the literature (14%), but note that uncertainties in our most metal-poor measurements make this an upper limit. We find 19% of stars in our UFD sample to be metal-rich ([Fe/H] > −2), consistent with the sum of literature spectroscopic studies. MW UFDs are known to be predominantly >13 Gyr old, meaning that all stars in our sample are truly ancient, unlike metal-poor stars in the MW, which have a range of possible ages. Our UFD metallicities are not well matched to known streams in the MW, providing further evidence that known MW substructures are not related to UFDs. We include a catalog of our stars to encourage community follow-up studies, including priority targets for ELT-era observations.

Les études récentes sur le développement ont montré l’importance des capacités précoces de communication sociales du nouveau-né humain, et leur caractère fonctionnel dès la naissance. La capacité de participer activement au dialogue social est la principale des nombreuses compétences du bébé qui attendent d’être mises en œuvre au sein des interactions précoces avec les parents. Cependant la mise en jeu au meilleur niveau, et le démarrage subséquent du développement intersubjectif peuvent être gênés par des causes liées aux parents, dépression post natale en particulier, ou liées au bébé, prématurité et ou retard de croissance. Le but de cette étude pilote est de confirmer l’âge de début du premier sourire social, de donner une évaluation du taux de plaisir partagé, à 2 et 3 mois postpartum, à comparer avec ceux de la littérature et de confirmer les corrélations entre Plaisir partagé, retrait relationnel évalué avec l’échelle M-ADBB, et le poids de naissance et l’âge gestationnel, ainsi qu’avec l’évaluation du tempérament du bébé par l’échelle IBQ, dans sa validation en français, et enfin avec le sexe. Un second objectif est de tester la faisabilité en routine de la proposition à faire aux parents de participer à une situation de face à face avec leur bébé, pendant 5 minutes pour chaque parent, enregistrée en vidéo, qui permet de faciliter les échanges positifs en face à face. Cette étude prépare une recherche longitudinale plus large sur le développement intersubjectif et ses troubles, reprenant les prémices de la recherche PREAUT de dépistage précoce de l’autisme, avec la recherche d’algorithmes de cotations du plaisir partagé et du retrait relationnel, dans la perspective de mettre au point des applications permettant aux professionnels de coter en routine des éléments importants du développement intersubjectif premier sourire social, plaisir Partagé, comportement de retrait relationnel du bébé, capacité d’accordage affectif, et prédictivité de ces éléments sur le devenir ultérieur en termes de troubles du neurodéveloppement. Le but final de l’étude étant de montrer les effets préventifs de la guidance interactive développementale précoce, entre 1 et 3 mois, centrée sur l’augmentation du plaisir partagé sur le développement intersubjectif, le développement psychomoteur et le développement cognitif.

La quête de sens au travail face à la pénibilité
Authors: Karam-Leder Nina
Published: November 2023

La question du sens au travail permet d’apporter un éclairage sur l’ambivalence actuelle du rapport au travail : plutôt que de voir dans les tensions du marché du travail le signe d’une perte de centralité du travail, il convient davantage d’y voir l’expression d’une attention plus grande à sa portée sociale mais aussi à son organisation. À ce titre, la question du sens du travail engage celle de son organisation concrète, de la pénibilité et de la santé au travail.
Figeage, empêchement, procuration
Authors: Lemieux Cyril
Published: November 2023

Qu’est-ce que l’inactivité professionnelle fait à la politisation ? À partir du cas des retraités, des chômeurs et précaires et des « femmes au foyer », le sociologue Cyril Lemieux montre que le fait d’être sans emploi tend à occasionner, pour les personnes concernées, une politisation figée, empêchée ou vécue par procuration. Mais ces obstacles à une citoyenneté politique active ne signifient pas pour autant une dépolitisation. C’est ce qui plaide, plus encore que pour l’idée de « droit au travail », pour celle d’un « droit social universel à l’intégration professionnelle », seul à même de libérer au sein de la société le potentiel de politisation des personnes dites « inactives ».
Hiérarchies au travail sur les plateaux de tournage
Authors: Rot Gwenaële
Published: November 2023

À l’heure où l’on parle de « libérer l’entreprise » en s’émancipant du modèle bureaucratique et où il est de bon ton d’interroger la légitimité de la hiérarchie en insistant sur son inadaptation par rapport aux exigences de changement et d’innovation, que peut nous apprendre le cinéma comme espace professionnel caractérisé, depuis sa naissance, par une très forte flexibilité ? La fragilité des positions dans un système où il faut en permanence surmonter des difficultés et où la réputation professionnelle conditionne l’employabilité, conduit à accepter, plus que dans bien d’autres milieux professionnels encadrés par des règles bureaucratiques protectrices, des formes de violence sociale.
La « fonction-Dante » dans la philosophie. Une note à propos de Georg Simmel
Authors: Robiglio Andrea A.
Published: November 2023

Résumé – Cette note vise à mettre en évidence une « fonction Dante » dans l’œuvre du philosophe allemand Georg Simmel (1858-1918). L’intérêt précoce de Simmel pour les écrits et la pensée de Dante Alighieri est bien documenté. Dante a accompagné Simmel depuis le début de sa carrière (en 1884, il a publié une étude consacrée à « La psychologie de Dante ») jusqu’à ses écrits de maturité. Bien que cet aspect n’ait pas encore été approfondi par les chercheurs, il est possible de montrer la présence d’une inspiration singulière et durable qui, née de la méditation de l’œuvre de Dante, aurait conduit le penseur allemand à approfondir des éléments essentiels de sa propre vision philosophique.
L’ordinaire de la famine
Authors: Chanlat-Bernard Eléonore
Published: November 2023

En puisant dans les sources de la pratique administrative coloniale britannique, cet article interroge la différenciation des corps dans le cadre des interactions que produit la famine entre administrateurs et administrés au Bengale au xix e  siècle. La crise que la famine impose aux corps trouble les rituels coloniaux d’interaction. Mais les interactions avec les corps affamés, tout en multipliant les opportunités de les examiner de près, contribuent aussi à normaliser la famine.
Mise en scène de soi d’un chef en situation coloniale (Togo allemand, 1887-1914)
Authors: Gozo Kodzo
Published: November 2023

L’article étudie les procédés d’accueil et de présentation de soi de Gidi-Gidi, un commerçant éwé, dans ses interactions avec des explorateurs et administrateurs allemands qui l’ont rencontré avant et pendant la mise en place de l’administration impériale allemande au Togo, qu’il a contribué à installer dans une des régions stratégiques du Togo entre 1887 et 1914. Face aux Allemands avec lesquels il coopère, il se présente comme un membre de l’élite locale et un « évolué ». L’article analyse ses techniques corporelles et leur impact autant sur les interactions que sur son parcours personnel pendant l’ère impériale allemande. Il étudie les ressorts des relations, notamment ce qu’elles disent des différences corporelles ressenties.
Care et corps dans les relations de domesticité au Kenya et en Rhodésie du Sud (années 1920-1940)
Authors: Surun Isabelle
Published: November 2023

Les employés domestiques présents dans tous les foyers des colons et des coloniaux sont placés au plus près de l’intimité familiale, mais ils sont toujours ramenés à une différence qui structure la domination coloniale. Ils assument des tâches qui touchent aux fonctions corporelles de leurs maîtres, mais leur corps constitue à la fois un marqueur de la différence, un lieu et un vecteur de transformation sociale et culturelle par l’inculcation de règles d’hygiène et de pratiques domestiques définies selon les normes européennes. Cette tension entre proximité et mise à distance fait de la domesticité coloniale un observatoire privilégié d’une domination inscrite dans la différence des corps. Cet article propose une « description dense » des interactions ordinaires entre maîtresses de maison européennes et serviteurs africains dans le quotidien de la vie domestique. Il s’appuie sur le vaste corpus des écrits de Karen Blixen et Doris Lessing, ainsi que sur le témoignage de l’ancien cuisinier de Karen Blixen, Kamante Gatura.
Pascal aux limites de la philosophie : permanences et reconfigurations d’une figure philosophique
Authors: Barancy Félix
Published: November 2023

Pascal semble toujours s’être tenu dans les marges de l’historiographie philosophique. Cette situation tient d’abord à la méfiance explicite qu’il nourrit à l’égard des « philosophes ». Mais elle s’explique aussi par l’influence d’un acteur décisif dans l’institutionnalisation de la discipline : Victor Cousin. Pour le montrer, nous étudions les effets produits sur le long terme par la construction d’une « figure philosophique » qui articule, sous le nom de Pascal, des textes et un contenu philosophique spécifique, en se focalisant sur sa réception chez Havet, Brunschvicg et Heidegger. Un tel retour historique permet de mettre en évidence des points aveugles dans notre interprétation de ce que peut être la philosophie de Pascal, voire dans notre conception de ce qui constitue l’en dehors de la philosophie en général. Il offre en outre un éclairage original sur les opérations de sélection qui ont présidé à la constitution de ce que nous appelons notre « modernité » philosophique.
Le tabac chauffé est-il un outil de réduction des risques ?
Authors: Thomas Daniel
Published: November 2023

Le tabac chauffé (TC), nouveau produit du tabac, est présenté par l’industrie du tabac comme une alternative efficace et sûre à la cigarette. Même si les quantités de composés nocifs pour la santé émises par le TC sont inférieures à celles trouvées dans la fumée de cigarette, cette diminution d’exposition ne peut être assimilée à une réduction des risques. Aucune étude n’a apporté la preuve que le passage de la cigarette au TC réduisait le risque des maladies liées au tabac. Le TC ne peut pas être considéré comme un produit de sevrage de la cigarette et a même été conçu comme un produit pour entrer dans la consommation de tabac ou y revenir. Pour faire la promotion de ce produit, l’industrie du tabac exploite essentiellement le concept de réduction des risques et, à ce titre, essaie dans sa communication commerciale de créer la confusion entre le TC et la cigarette électronique alors que ces deux produits n’ont rien à voir. Cette promotion s’appuie, d’une part, sur les données d’études internes contradictoires avec celles d’études indépendantes, d’autre part, de façon illégale, sur les réseaux sociaux et une communication en contradiction avec les avis des autorités de régulation. Le TC est un nouveau leurre de l’industrie du tabac, destiné à assurer le maintien de ses profits dans un monde qui s’éloigne de la cigarette « traditionnelle ». Il doit être formellement déconseillé, tant aux non-fumeurs qu’aux fumeurs.

The increasing demand for free-range poultry products has led to a surge in their availability in the market, prompting a potential decline in premium prices associated with these products. This shift places considerable pressure on upstream costs in chicken production. A comprehensive under-standing of its impact on the environment is essential to ensure the success of commercial and industrial free-range chicken production. However, there exists a significant knowledge gap concerning the emission and concentrations of volatile organic compounds (VOCs) from organic-free range chicken, and their environmental implications have yet to be understood. We aim to address this critical knowledge gap by elucidating the role of VOC emissions in chicken production and assessing their impact on human and animal health, as well as environmental challenges. Understanding the implications of VOC emissions is essential for promoting sustainable and responsible free-range chicken farming practices. By identifying the sources of VOC emissions and their impacts, stakeholders can implement appropriate measures to optimize air quality and enhance the well-being of chickens and workers. Ultimately, this review highlights the role of VOCs in animal production, providing valuable insights for improving the efficiency, environmental sustainability and welfare aspects of free-range chicken farming.
L’intersection entre orientation sexuelle et religion à la frontière de la protection internationale
Authors: Ferrari Daniele
Published: November 2023

L’article propose une réflexion sur la relation entre religion et orientation sexuelle dans le statut de réfugié des personnes lesbiennes, gays et bisexuelles (LGB). Cette relation est analysée à travers le concept novateur de persécution intersectionnelle suivant quatre étapes : l’intersectionnalité en tant que méthodologie, les facteurs de l’intersection, les causes de l’intersection et les effets de l’intersection. Partant d’une lecture intersectionnelle des documents du Haut-Commissariat pour les réfugiés des Nations unies, notre réflexion mobilise l’intersectionnalité dans la perspective d’une méthodologie utile à développer une meilleure garantie de la protection internationale des personnes LGB, sans renoncer à mettre en évidence les difficultés liées à l’application de ce concept.
