La blonde d’à côté : Sophie Daumier
Authors: François-Denève Corinne
Published: December 2024

Abstract: Au Père-Lachaise, la tombe de Sophie Daumier attire des visiteurs qui parlent d’elle comme « la femme de Guy Bedos, qui faisait des sketchs avec lui ». En effet, Sophie Daumier (1934–2004) a été entre 1965 et 1977 la femme et la partenaire de Guy Bedos : de leur duo sont demeurés célèbres des sketches (parfois écrits par Jean-Loup Dabadie) comme « les vacances à Marrakech », « la drague » ou « la rupture ». Daumier, jeune, blonde, « sexy », semble y être cantonnée au rôle décoratif de faire-valoir tête-à-claques d’une performance qui reprend tous les clichés genrés de l’époque. La lecture des mémoires amers de Sophie Daumier (Parle à mon cœur, ma tête est malade, 1979) déroule toutefois une toute autre histoire – celle d’une femme née dans les années trente, dans une famille quelque peu dysfonctionnelle, qui fait tôt l’expérience de la violence domestique ; qui devient « fille-mère » à 20 ans, et tente de vivre de la danse, puis de la comédie, pour triompher au cinéma, mais aussi au théâtre, dans des pièces de Marcel Achard ou de Jean Anouilh. Autrice de spectacles pour femmes, jamais joués, faute de producteurs, de chansons douces-amères, souvent metteuse en scène costumière et régisseuse des spectacles de Bedos, Sophie Daumier est une femme humoriste piquante et douée, sensible aux combats féminins du temps, mais finalement invisibilisée. Le présent article voudrait revenir sur la trajectoire méconnue de celle qui ne fut pas seulement « la partenaire de ».
Optimization of crystal length in a pulse-pumped up-conversion single-photon detector for decoding femtosecond time-bin qubits

Published: December 2024

In advancing ultrafast quantum communication and computing, it is crucial to develop precise time-resolved measurement techniques for single-photon pulses. However, the measurement of photonic qubits, especially time-bin qubits, is limited by the temporal resolution of single-photon detectors, typically around tens of picoseconds. In this study, we developed a pulse-pumped up-conversion single-photon detector (UCSPD) using periodically poled Mg-doped stoichiometric lithium tantalate (PPMg: SLT) crystals of varying lengths to optimize femtosecond up-conversion. We evaluated the UCSPD’s efficiency and temporal resolution using a convolution model that accounts for group delay in nonlinear crystals. Our results demonstrate that the model calculations enable the accurate prediction of the crystal length dependence of temporal resolution and up-conversion efficiency without fitting parameters. The UCSPD achieved 415 fs resolution and 10.1 % efficiency with a 2 mm crystal, enabling successful characterization of time-bin qubits with 800 fs pulse intervals.

In einer zunehmend herausfordernden Geschäftsumgebung besteht für kleine und mittlere Business-to-Business Unternehmen die Herausforderung, ihre Geschäftsprozesse und die unternehmensweiten Anwendungssysteme entsprechend der Technologielandschaft anzupassen, um konkurrenzfähig zu bleiben. Der zielgerichtete Einsatz von Künstlicher Intelligenz birgt das Potenzial für Effizienzsteigerung und Unterstützung in verschiedenen Geschäftsbereichen, darunter auch Marketing und Vertrieb. Trotz der zunehmenden Bedeutung von Künstlicher Intelligenz bleibt der Einsatz in kleinen und mittleren Unternehmen oft zögerlich. Das Ziel dieser Studie ist die Herleitung eines ganzheitlichen Ansatzes für eine mit KI-Werkzeugen unterstützte Customer Journey. Diese Arbeit untersucht dafür speziell den potenziellen Einsatz von Künstlicher Intelligenz in der Kundenkommunikation von kleinen und mittleren Unternehmen im produzierenden B2B-Sektor. Basierend auf zehn leitfadenorientierten qualitativen Interviews mit Praktikern aus produzierenden B2B-KMU werden deren spezifische Herausforderungen in der Kundenkommunikation identifiziert und der Einsatz von KI als potenzielle Lösung geprüft. Die Ergebnisse zeigen, dass der Einsatz von KI in der Kundenkommunikation produzierender B2B-KMU Potenzial birgt, um bestehende Herausforderungen zu mindern, wobei die Einsatzmöglichkeiten je nach Datenverfügbarkeit variieren. Die vorliegende Arbeit trägt dazu bei, produzierenden B2B-KMU aufzuzeigen, wie sie Künstliche Intelligenz einsetzen können, um ihre Herausforderungen zu bewältigen und die Kundenkommunikation zu optimieren.
Deep learning analysis of fMRI data for predicting Alzheimer’s Disease: A focus on convolutional neural networks and model interpretability
Authors: Zhou Xiao , Kedia Sanchita , Meng Ran , Gerstein Mark
Published: December 2024

The early detection of Alzheimer’s Disease (AD) is thought to be important for effective intervention and management. Here, we explore deep learning methods for the early detection of AD. We consider both genetic risk factors and functional magnetic resonance imaging (fMRI) data. However, we found that the genetic factors do not notably enhance the AD prediction by imaging. Thus, we focus on building an effective imaging-only model. In particular, we utilize data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI), employing a 3D Convolutional Neural Network (CNN) to analyze fMRI scans. Despite the limitations posed by our dataset (small size and imbalanced nature), our CNN model demonstrates accuracy levels reaching 92.8% and an ROC of 0.95. Our research highlights the complexities inherent in integrating multimodal medical datasets. It also demonstrates the potential of deep learning in medical imaging for AD prediction.
Painting’s correspondence
Authors: Fortnum Rebecca , Chorpening Kelly
Published: December 2024

How might a painter or a painting correspond? In this dialogue, artists Rebecca Fortnum and Kelly Chorpening explore the ambiguity of the word correspondence as a creative method in painting. They examine the word as a set of equivalences or affinities, forged through the act of painting, as well as painting as a form of address. They evoke Charles Baudelaire’s poem ‘Correspondences’ (1857) and its many translations as a starting point to explore how things and ideas co-respond. Their discussion thinks through the relation between touch and sight within the painting process and how gestures or marks represent spatial dimensions and materialities. Debating ideas of mediation and copying suggested by the notion of correspondence, they propose that the term may be useful in allowing painters to forge multiple and varied connections and explore coincidences with and through their subject. Painting is positioned as a form of co-response that happens across time, allowing the painter to form correlations between past and present.

Sobre la reciprocidad de naturaleza y cultura. La Cognición 4E y su perspectiva arqueológica en el paisaje
Authors: Muñoz Herrera Antonio
Published: December 2024

En el ámbito arqueológico, una de las ultimas fronteras de conocimiento se ha situado en el entendimiento de la mente antigua a través de sus restos materiales. En las últimas décadas, aprovechando las innovaciones técnicas y epistemológicas, se ha abierto un nuevo abanico de posibilidades para este tipo de estudios. La llamada arqueología cognitiva nace para resolver el problema paradigmático entre naturaleza y cultura y para intentar estudiar los procesos cognitivos de las sociedades pasadas en la creación y desarrollo cultural que se dio en ellas. El presente estudio pretende poner en valor dicha especialidad arqueológica, haciendo un repaso de su historiografía y poniendo de relevancia uno de los campos de estudio de esta especialidad que es la llamada cognición 4E. Por último, proponemos la inclusión del paisaje como un elemento fundamental de estudio dentro de esta especialidad, por su influencia y rol en el desarrollo cultural, como han demostrado estudios muy recientes. Una aproximación donde las barreras entre ciencias exactas y sociales debe romperse para obtener un mejor entendimiento de la cultura como totalidad.
Selective breeding and taxonomy of laccate Ganoderma species originating from Finland
Authors:   University of Eastern Finland, Faculty of Science, Forestry and Technology, School of Forest Sciences, Cortina-Escribano Marta
Published: December 2024

Ganoderma lucidum has been widely cultivated worldwide due to its bioactive compounds. Agricultural and forestry by-products have been used as growth substrate for the cultivation of G. lucidum. In Finland, there are high volumes of wood biomass by-products that could be used for the cultivation of this fungal species. A laccate Ganoderma species resembling G. lucidum occurs naturally in Finnish forests, but there is lack of information on the wild population. To cultivate Finnish strains of G. lucidum, it is essential to study the variability of the wild populations of the species and select the most appropriate for the industrial use. In this dissertation, the phenotypic variation, the cultivation practices, the β-glucan content, and the phylogeny of laccate Ganoderma originating from Finland have been explored. The growing conditions were adjusted, and the suitability of the strains, supplements, and substrates tested. Finnish strains of G. lucidum were successfully cultivated using wood by-products as substrate. A cold shock treatment of the colonized substrate was needed to trigger the formation of fruiting bodies. Substrates based on Populus tremula and Betula sp. sawdust and wood chips increased the probability of fruiting, fruiting body yield, and β-glucan content of G. lucidum. Substrate based on Pinus sylvestris wood was not suitable for mushroom production, but the fermentation by G. lucidum decreased the lignin content of pine wood, which could be a potential pretreatment for pulping industries. Phenotypic variability of the strains was noted based on mycelial growth, mycelium and fruiting body morphology, fruiting body yield, and their ability to produce β-glucan. Despite the phenotypic variation observed within the Finnish G. lucidum populations, the Finnish isolates presented nearly identical gene regions based on multiple gene regions and grouped together in the phylogenetic trees generated. The Finnish strains of laccate Ganoderma were confirmed to represent a single species according to the phylogenetic analysis. More specimens and molecular data are needed to clarify the classification of laccate Ganoderma from Finland.
Can Immersive Storytelling Lead Us Through the Wilderness of Climate Chaos? Maybe. But We've Got Some Bushwhacking to Do.
Authors: Snyder Michael
Published: December 2024

Modern immersive storytelling technologies, such as virtual and mixed reality, present an exciting opportunity to expand awareness and grow empathy around pressing issues like climate change, species loss, and habitat destruction. But does â€œthe ultimate empathy machineâ€, as Chris Milk dubbed virtual reality in his recent TED talk, truly possess the power to lead us through the wilderness of climate chaos and into a brighter future? Here we examine how an overfocus on sensory stimuli and the removal of the centrality and primacy of the external storyteller in immersive spaces may be undermining its transformative power as a storytelling medium. To recapture the potential of immersive storytelling as a tool for social impact, we turn to lessons learned from wilderness therapy, a practice steeped in seeking a balance between guided and self-directed learning in uncharted space. In summary, we conclude that if we want our immersive stories to be more than visually stimulating parlor tricks, we will need to embrace embodied, communally engaged methodologies that are multi-modal and embedded with trusted guides who can lead audiences through the wilderness of experience to vistas of new understanding.
Derecho a la educación superior: acceso, regulación y discriminación en las fuerzas armadas chilenas
Authors: Díaz Bravo Enrique
Published: December 2024

El Legislador orgánico chileno proyectó la educación como un proceso, con una finalidad determinada, la que se debe alcanzar dentro de un marco de mínimos democráticos al servicio de los intereses generales, con pleno reconocimiento de los derechos y garantías de las minorías. La Ley General de Educación fijó el contenido del derecho a la educación y amplió su alcance democrático a un conjunto de principios y valores que se centran en la función social de la educación. En ese entramado normativo se encuadra la formación de los miembros de las Fuerzas Armadas, respecto de las que el ordenamiento jurídico considera que, para alcanzar el cumplimiento de sus funciones propias se dispone la existencia de una serie de establecimientos de educación superior que preparan a sus miembros. En este trabajo se analizan críticamente los requisitos de ingreso a las Escuelas de las Fuerzas Armadas y la afectación al principio de igualdad que algunos de dichos requisitos provocan, contrariando los principios de igualdad y no discriminación, en especial los requisitos de estado civil y ausencia de cargas familiares.
Resoluciones sobre prácticas monopólicas y concentraciones: marco legal y práctica
Authors: Saldaña Pérez Juan Manuel
Published: December 2024

En este trabajo se analiza, desde una perspectiva teórica y práctica, el marco jurídico que regula la competencia económica en México: la autoridad resolutora, es decir la Comisión Federal de Competencia Económica (la Comisión) sus resoluciones, sanciones, medios de impugnación, conflictos competenciales con el Instituto Federal de Telecomunicaciones y Radiodifusión (el Instituto) y demás problemática que implica la existencia de dos autoridades en la materia. En particular se analizan tres figuras anticompetitivas reguladas en la legislación mexicana, las prácticas monopólicas absolutas, las prácticas monopólicas relativas y las concentraciones. Es compleja la materia de competencia económica y escasa la literatura al respecto, por lo que en el presente ensayo, a efecto de alcanzar una mejor comprensión, se estudian algunos casos resueltos por la Comisión, relativos a estas tres figuras anticompetitivas, en donde participaron agentes económicos tanto del sector público (funcionarios) como del sector privado (empresarios), destacando la relevancia de los asuntos en que se vulneran derechos humanos relativos a la salud y la alimentación.

Published: December 2024

Pantai Tirang menerima aliran nutrien dari Sungai Silandak yang hulunya berada di kawasan perumahan, tambak, pariwisata, dan aktivitas antropogenik. Hal tersebut menghasilkan limbah maupun nutrien salah satunya silikat. Silikat adalah nutrien yang dapat meningkatkan produktivitas primer suatu perairan yang ditandai dengan meningkatnya klorofil-a. Dinamika arus berpengaruh terhadap persebaran nutrien secara horizontal sesuai dengan pergerakan massa air.  Penelitian ini bertujuan untuk memetakan sebaran horizontal dan menentukan tingkat hubungan dari konsentrasi silikat dan klorofil-a. Metode penelitian yaitu kuantitatif dengan analisis deskriptif. Penelitian dilakukan pada bulan September 2022 dengan metode purposive sampling untuk pengambilan sampel. Analisis konsentrasi silikat menggunakan metode molybdosilicate, konsentrasi klorofil-a menggunakan metode spektrofotometri dan analisis hubungan keduanya dengan korelasi pearson. Hasil dari penelitian menunjukkan nilai konsentrasi silikat berkisar antara 0,3337 – 1,0836 µM dan konsentrasi klorofil-a berkisar antara 0,7147- 118,1891 mg/m3. Hasil uji korelasi menunjukkan signifikansi positif (P < 0,001; r = 0,989; R2 = 0,978) dan memiliki hubungan sangat kuat. Sementara itu, tinggi rendahnya konsentrasi silikat dan klorofil-a tidak dipengaruhi oleh arus melainkan dipengaruhi oleh sumber masukan di muara sungai.

Published: December 2024

Kenaikan permukaan air laut merupakan ancaman serius di kawasan pesisir, khususnya di kota-kota pelabuhan seperti Jakarta, Semarang, dan Surabaya yang terletak di Laut Jawa. Penelitian ini bertujuan untuk menganalisis interaksi antara anomali tinggi muka air laut dari data satelit Altimetri AVISO, suhu permukaan laut, dan faktor oseanografi serta atmosfer lainnya. Peningkatan suhu permukaan laut akibat variasi iklim berkontribusi pada ekspansi termal air laut, yang pada gilirannya meningkatkan rata-rata tinggi muka air laut. Dinamika perairan yang menyebabkan anomali tinggi muka air laut secara spasial, dipengaruhi oleh pola musim dan fenomena seperti ekman transport, teramati berperan penting dalam redistribusi suhu permukaan air laut. Puncak anomali tinggi muka air laut terjadi pada bulan Mei, dengan tinggi anomali mencapai +0,2 m, yang bersamaan dengan suhu air laut sebesar 32°C dan transport ekman ke arah selatan. Sehingga, secara spasial anomali tinggi muka air lebih tinggi di pantai utara Pulau Jawa. Hasil analisis menunjukkan bahwa anomali tinggi muka air laut berkorelasi positif dengan suhu permukaan laut. Melalui analisis Principal Component Analysis (PCA), ditemukan bahwa dua komponen utama (F1 dan F2) menyumbang total 78,47% dari variabilitas data, dengan F1 menjelaskan 58,86% dan F2 menjelaskan 19,61%. Hubungan antara suhu permukaan laut dan anomali tinggi muka air laut tercermin pada vektor yang lebih panjang, menunjukkan pengaruh signifikan kedua variabel ini terhadap dinamika laut. Temuan penelitian ini memberikan wawasan penting untuk pengelolaan sumber daya kelautan dan strategi penanggulangan dampak variasi iklim yang lebih efektif di wilayah pesisir.

The study’s objective was to estimate the association among various linear body measurements and body weights of adult Kacang goats. The data was obtained from 209 heads of adult Kacang Goat, compressed 78 bucks and 131 ewes. The morphological evaluation was performed by measuring body weight (BW), body length (BL), chest depth (CD), chest girth (CG), chest width (CW), and withers height (WH). Factor PROCEDURE was performed to estimate the principal component. The result of factor analysis was used to determine the independent variable for linear regression analysis. BW has a favorable correlation with CG, BL, CD, CW, and WH for bucks and ewes. PC 1 accounts for 55.62% of the variation in bucks, while PC 2 accounts for an additional 18.34%. PC 1 accounts for just 0.45% of the overall variation in ewes, whereas PC 2 accounts for 0.24%. The R-squared (R2) values for bucks and ewes in the regression equation with CG as the independent variable are 0.32 and 0.41, respectively. For both bucks and ewes, the regression equation with CW as the independent variable had a higher R2 of 0.52 and 0.20, respectively. For bucks and ewes, the regression equation'sR2 values are 0.54 and 0.44, respectively, with combined CG and CW acting as independent variables. This integrated approach to analyzing body measurements in Kacang Goats provides a robust foundation for making informed decisions in goat farming.

Published: December 2024

Chaetodon octofasciatus is a species of fish in the Chaetodontidae family, commonly known as an indicator fish in the reef ecosystem as the frequency of its appearance in the wild can interfere with the state of the coral reef ecosystem in the waters. Panjang Island is located in Jepara, Central Java, Indonesia, in which one method of coral reef ecosystem rehabilitation in a a form of Artificial Patch Reef (APR) has been implemented. This study aims to investigate the levels of C. octofasciatus predation on corals in the APR and Natural reef of Panjang Island. We used the LIT (Line Intercept Transect) to measure the density of coral reefs at both locations. The abundance of C. octofasciatus was calculated using the Belt Transect method, while selectivity and bite ratio was observed and counted every 5 minutes. The results shows that C. octofasciatus from natural reefs have the highest predation rate (185 bites/5 min) and mostly eat the coral with lifeform massive while the ones from APR shows 144 bites/5 min and mostly eat the coral with lifeform Acropora branching. This selectivity could be due to the availability of corals in both areas. While massive corals were highly available in the natural reefs, branchich corals esp. Acropora is mostly planted in the APR. A more diverse coral lifeform in the natural reef also showed the type of corals that are less selected by C. octofasciatus such as submassive corals and Acropora tabulate, as well as corals with the foliose life form.

Published: December 2024

The coastal waters of Teluk Awur, Jepara are affected by human activities such as aquaculture, tourism, agriculture, and settlements. The number of human activities on land will contribute to high suspended solids (TSS) entering coastal waters by run-off. The high TSS in coastal areas will affect the entry of light intensity, disrupting the photosynthesis process and ecosystem. This study compares TSS values based on Landsat images using several TSS algorithms such as Wirasatriya, Budhiman, Ajiperwata, and Parwati algorithms and the algorithm resulting from the July 2023 field data calibration against red reflectance. The algorithm's performance from calibration has a smaller error value with RMSE = 8.51, MAPE = 25.77%, and Bias = 7.52. TSS estimation from Landsat 8 satellite imagery has a range of values of 30.56 - 62.55 mg/L (average 35.60 mg/L), while field measurements of TSS values are 22.40 - 64.52 mg/L (average 32.69 mg/L). This research will be valuable information for using the right Landsat-8 algorithm for temporal and sustainable TSS monitoring. It can be used in abrasion monitoring and management in the Teluk Awur coastal waters of Jepara.

Published: December 2024

The primary issue at the Gracilaria verrucosa seaweed cultivator is the low productivity associated with current cultivation methods. Analyzing cell number and agar content provides valuable insights into seaweed cultivation productivity, growth activity, nutrient absorption, and chemical composition. This research aims to examine how variations in planting distance affect the cell number and agar content of Gracilaria verrucosa. The research was conducted at the Maranak Experimental Pond Installation, Brackish Water Aquaculture Fisheries Research Institute, located in Marannu Village, Lau District, Maros Regency. Analysis of cell numbers and agar content was performed at the Fisheries Research Institute Laboratory of the Brackish Water Aquaculture Center from June to July 2024. Utilizing a completely randomized quantitative experimental design with four treatments and three repetitions, the research included: Treatment A (planting distance 20 cm), Treatment B (30 cm), Treatment C (40 cm), and Treatment D (50 cm). The results indicated that planting distance significantly impacts cell number, with the 50 cm distance yielding the highest average cell count of 213.00 ± 9.64. Similarly, planting distance affects agar content, with the 50 cm distance producing the highest agar content of 27.31%. Therefore, a planting distance of 50 cm is identified as the most effective, resulting in both the highest number of cells and agar content.

Published: December 2024

Mangroves are plants that live in muddy substrates, muddy sand, sand to tidal areas. These plants have important roles for marine organisms, carbon sequestration, as shoreline protectors from waves or erosion and sediment filters before entering the sea. The influence of human activity in the form of conversion of mangrove land to other forms or caused by natural disasters is a dangerous threat to the mangrove ecosystem. The magnitude of mangrove cover change is an important component so information is needed on changes in the spatial and temporal distribution of mangrove cover. This study aims to temporally analyze mangrove cover using high-resolution satellite imagery on the West Coast of Bangkalan Regency. This research uses secondary data in the form of Planetscope high-resolution satellite images from 2018 - 2023. The data will be processed to determine changes in mangrove area using Fv (Fractional Vegetation Cover). Calculation of the Fv (Fractional Vegetation Cover) value is done from the results of the minimum and maximum values of NDVI (Normalized Difference Vegetation Index). The results showed that there was a change in mangrove cover which was initially included in the FVC (Full Vegetation Coverage) class in 2022 with an area of 41.12 Ha to the HVC (High Vegetation Coverage) class with an area of 84.82 Ha in 2020. At the Arosbaya location, the highest Fv value occurred in 2019 with an area of 206.48 Ha. Reduction of mangrove area occurred in Sepulu and Arosbaya sub-districts due to land use change and sedimentation.

The northern coast of Central Java is a strategic development area, but it has the potential for high wave disasters. Planning activities and mitigating maritime disaster risks requires an understanding of wave characteristics. This study analyzes wave characteristics in the northern waters of Central Java using the Wavewatch III numerical model. Significant wave height and wave direction were averaged from 2014 to 2023. The results showed that wave conditions in the northern waters of Central Java tend to be higher in December, January, February, July, August, and September. Meanwhile wave conditions tend to be lower in March, April, May, June, October, and November.

Aim. To determine the prevalence and risk factors of emotional burnout among medical workers of a neurosurgery center.
Materials and methods. In 2022–2024, a prospective study of the medical staff involved in emergency care for patients with acute ischemic stroke, in particular mechanical thrombectomy, was conducted at the Center for X-ray Endovascular Neurosurgery of Kyiv City Clinical Hospital No. 1. The mean age of the sample was 32.2 ± 5.8 years. The sex structure was: 40 (80.0 %) men and 10 (20.0 %) women. The clinical-psychopathological, psychodiagnostic and statistical methods were used. The psychodiagnostic method was implemented by using the Maslach Burnout Inventory (MBI, C. Maslach et al., 1997).
Results. It has been determined that such a criterion as the sex of neurosurgery center medical staff did not affect the severity of any component of emotional burnout (p > 0.05). Statistically significant differences in the prevalence of high rates of emotional burnout components have been found between groups of medical staff with different specializations. Namely, it has been revealed that working in the center as a neurosurgeon was significantly associated with high rates of such components as “Emotional exhaustion” (p = 0.04) and “Depersonalization” (p = 0.006). A direct correlation has also been established between the total work experience, length of service at the neurosurgery center and the number of working hours per month with the intensity of emotional burnout manifestations in the selected contingent of individuals.
Conclusions. The prevalence of emotional burnout among medical staff of the neurosurgery center has been established for various components of this phenomenon: “Emotional exhaustion” – 52.0 %, “Depersonalization” – 40.0 %, “Reduction of personal achievements” – 50.0 %, indicating a high level of stress and negatively affecting the mental health of the selected contingent. The risk for developing emotional burnout among the medical staff rises with increasing workload, length of service and work experience at the center. An absolute risk factor for emotional burnout is a neurosurgical practice. The development of psychotherapeutic measures aimed at overcoming the manifestations of emotional burnout in medical workers and increasing their resilience to stressful working conditions of the neurosurgery center is promising.

Aim: to investigate the content of eNOS in the blood serum of patients with coronavirus disease (COVID-19) with pneumonia in association with hemostatic parameters and to determine its prognostic value in assessing the risk of oxygen dependence and death.
Material and methods. There were 123 patients with COVID-19 with pneumonia under observation. All patients were examined and treated in accordance with the Order of the Ministry of Health of Ukraine No. 722 dated 28.03.2020. The eNOS content in the patients’ serum was determined by enzyme-linked immunosorbent assay.
Results. It was found that the content of eNOS in the blood serum of patients with COVID-19 with pneumonia at the time of hospitalization was 9.0 [7.0; 12.0] days lower (p < 0.001) than in healthy subjects. The development of oxygen dependence in patients with COVID-19 with pneumonia was accompanied by worsening of endothelial dysfunction and procoagulant changes, which was confirmed by a decrease in the content of eNOS in the blood serum (p < 0.001), an increase in the level of fibrinogen (p < 0.05) and D-dimer (p < 0.05). The threshold level of eNOS in the blood serum ≤327.09 pg/ml (AUC = 0.861, p < 0.001) was predictive of the onset of oxygen dependence. In patients with COVID-19 with pneumonia who subsequently died, at the time of hospitalization, eNOS levels were lower (p < 0.001) than in patients who recovered, which was combined with a higher level of D-dimer (p < 0.05) and its more frequent increase (p = 0.04) compared with patients who recovered. The eNOS content in the blood serum of patients with COVID-19 with pneumonia was correlated (p < 0.05) not only with the lethal outcome of the disease, but also with the formation of thrombotic complications, which occurred more often in patients with COVID-19 with pneumonia in the event of an adverse outcome (p = 0.0001). The threshold level of eNOS in the blood serum ≤201.75 pg/ml (AUC = 0.892, p < 0.001) was indicative of a high probability of death.
Conclusion. The eNOS content in the blood serum of patients with COVID-19 pneumonia at the time of hospitalization is lower (p < 0.001) than in healthy individuals, and the degree of its decrease depends on the severity of the disease, the development of oxygen dependence and the subsequent outcome of this disease. Limiting levels of eNOS in the blood serum of patients with COVID-19 pneumonia, which are important for predicting the risk of developing oxygen dependence and fatal outcome of the disease, have been established.
Putting on Sarah’s Skin: Victim Identity in the Abrahamic Stories and Beyond
Authors: Koci Katerina
Published: December 2024

This article explores the complex identities of Sarah and Hagar within the Abrahamic narratives, focusing on themes of victimhood and perpetration. It challenges feminist biblical interpretations that portray Sarah solely as a victim of patriarchal structures or postcolonial interpretations that see Sarah solely as a perpetrator, arguing instead for a nuanced understanding that recognizes her role as both a victim and an oppressor. The article highlights the unique as well as shared struggles of Sarah and Hagar against patriarchy, suggesting that their relationship is emblematic of broader issues of race, class, and gender dynamics. The analysis incorporates illustrations from the literature, urging a re-evaluation of Sarah's character in the light of contemporary discussions on oppression and complicity. By examining the narratives through the lens of cohabiting women, the article illustrates the complexities of their interactions and the implications for modern feminist discourse. Ultimately, it aims to liberate Sarah from her archetypal role, presenting her as a figure whose experiences resonate with the struggles of diverse individuals today, fostering a deeper understanding of victimhood, and promoting a non-violent response to systemic oppression.

Este artigo tem como objetivo analisar a profissão docente em escolas rurais nos munícipios de Rio Claro-SP e Uberlândia-MG entre 1950 a 1980. Para responder à questão de como ocorreu a formação das professoras, como ingressaram nas escolas rurais e quais práticas desenvolveram, utilizamos como fonte de pesquisa entrevistas com onze professoras e a legislação que regulamentou a profissão em ambos os estados. Concluímos que, a despeito das particularidades em sua formação e no ingresso na carreira, tanto as professoras leigas quanto as certificadas tinham que transpor as fragilidades da escola instalada em meio rural para ministrarem as suas aulas.

Fighting famine in the pages of the black press: newspaper O Exemplo (Porto Alegre, 1917-1919) O objetivo deste texto é abordar como a imprensa negra no Pós-abolição, especificamente o jornal O Exemplo de Porto Alegre, tratou a carestia de vida sentida pela população da cidade entre os anos de 1917 e 1919, bem como quais as estratégias de enfrentamento para o problema foram propostas pelo mesmo. Parto do entendimento de que as diferentes formas de organização negra na Primeira República foram essenciais para o alcance de direitos básicos para o conjunto da classe trabalhadora ao longo do século XX. Procuro, também, contribuir para os estudos que articulam a história social do trabalho, da Primeira República e o campo de estudos sobre o Pós-abolição no Brasil.Palavras-chave: Pós-abolição. Imprensa negra. Primeira República. Carestia. Abstract: This paper aims to approach how the black press in the post-abolition period, specifically Porto Alegre’s “O Exemplo” journal, addressed the cost of living felt by the population of the city between the years of 1917 and 1919, as well as which strategies were proposed by this communication vehicle to face that problem. Here, I start with the understanding that the different forms of black organization in the First Republic were essential for the achievement of basic rights by the whole working class throughout the 20th century. I also seek to contribute for studies which articulate the social History of work, History of the First Republic and the field of post-abolition studies in Brazil.Keywords: Post-abolition.

Workers and repression in the post-abolition in Alegrete/RS Tomando como fonte as documentações hospitalares e da cadeia municipal, no artigo pretendemos analisar os mundos do trabalho no município de Alegrete, interior do Rio Grande do Sul, e perceber quais as ligações entre trabalhadores pobres e, em especial, negros, com a política de repressão e tentativa de ordenamento social que tentava se colocar no início do período republicano. As fontes oferecem ricas informações sobre diversos sujeitos que passaram pelas duas instituições, a de saúde e a policial. Além disso, através de matérias publicadas em jornais locais, que eram transcritas por periódicos de diversas cidades do país, a pesquisa ainda mostra as transformações naquele município, onde viviam as e os trabalhadores em questão. Em suma, o que se evidencia é uma ligação entre trabalho e repressão, o que diz muito sobre um dos problemas históricos que configura o pós-Abolição no Brasil.Palavras-chave: Alegrete; Repressão; Pós-Abolição; Trabalhadores; Abstract: Taking as source hospital and municipal jail documents, in this article we intend to analyze the worlds of work in the city of Alegrete, interior of Rio Grande do Sul, and to understand the connections between poor workers and, in particular, blacks, with the policy of repression and effort to social ordering that was attempted at the beginning of the republican period. The sources offer rich information about several subjects who passed through the two institutions, the hospital and the jail. In addition, through articles published in local newspapers, which were transcribed by periodicals from several cities in the country, the research still shows the transformations in that municipality, where the workers in question lived. In short, what is evident is a link between work and repression, which says a lot about one of the historical problems that configures post-abolition in Brazil.Keywords: Alegrete; Repression; Post-Abolition; Workers;
