Measuring Optical Extinction toward Young Stellar Objects Using Diffuse Interstellar Bands
Authors: Carvalho Adolfo S. , Hillenbrand Lynne A.
Published: December 2022

Line-of-sight extinction estimates of well-studied young T Tauri and Herbig Ae/Be stars are based on many different measurements and analysis methods. This has resulted in wide scatter among the published A

V
values for the same star. In this work, we discuss the challenges in measuring extinction to actively accreting and especially outbursting young stellar objects (YSOs). We then explore a method not previously applied to young stars utilizing diffuse interstellar bands (DIBs). In early-type stars, narrow correlations exist between the DIB equivalent widths and the column density of interstellar material, and therefore the line-of-sight extinction. Here, we measure the equivalent widths of the 5780 and 6614 Å DIB features in a sample of actively accreting YSOs, and apply a DIB-reddening calibration to estimate reddening and subsequently extinction. Our calibration is newly derived from a composite of available literature data and fully accounts for the scatter in these measurements. We also compare the DIBs-inferred optical line-of-sight extinction values with previous extinction estimates for our sample stars.

Published: December 2022

Solar flares, especially the M- and X-class flares, are often associated with coronal mass ejections. They are the most important sources of space weather effects, which can severely impact the near-Earth environment. Thus it is essential to forecast flares (especially the M- and X-class ones) to mitigate their destructive and hazardous consequences. Here, we introduce several statistical and machine-learning approaches to the prediction of an active region’s (AR) flare index (FI) that quantifies the flare productivity of an AR by taking into account the number of different class flares within a certain time interval. Specifically, our sample includes 563 ARs that appeared on the solar disk from 2010 May to 2017 December. The 25 magnetic parameters, provided by the Space-weather HMI Active Region Patches (SHARP) from the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory, characterize coronal magnetic energy stored in ARs by proxy and are used as the predictors. We investigate the relationship between these SHARP parameters and the FI of ARs with a machine-learning algorithm (spline regression) and the resampling method (Synthetic Minority Oversampling Technique for Regression with Gaussian Noise). Based on the established relationship, we are able to predict the value of FIs for a given AR within the next 1 day period. Compared with other four popular machine-learning algorithms, our methods improve the accuracy of FI prediction, especially for a large FI. In addition, we sort the importance of SHARP parameters by the Borda count method calculated from the ranks that are rendered by nine different machine-learning methods.
A New Era of Intracluster Light Studies with JWST
Authors: Montes Mireia , Trujillo Ignacio
Published: December 2022

Still largely unexplored, the diffuse light in clusters of galaxies traces the past and ongoing buildup of these massive structures. Here we present the first comprehensive study of the intracluster light (ICL) of the cluster SMACS J0723.3–7327 (z = 0.39) using the JWST Early Release Observations. These deep and high spatial resolution images allow the study of the ICL with a high signal-to-noise ratio up to a radial distance of ∼400 kpc, twice as far with respect to previous HST studies of intermediate-redshift clusters. This opens up the possibility of exploring the rich mixture of processes that are building the ICL. We find that the inner parts of this cluster (R < 100 kpc) are built through a major merger, while the outer parts (R > 100 kpc) are mainly produced by the tidal stripping of Milky Way–like satellites. We also find that the slope of the stellar mass density radial profile of the ICL of this cluster (α
3D = −2.47 ± 0.13) closely follows the predicted dark matter halo slope (α
3D,DM = −2.6 to −2), supporting the idea that both components have a similar shape and thus the potential of using the ICL as a tracer of the dark matter distribution in clusters of galaxies. Future JWST studies of the ICL are set to revolutionize our understanding of cluster formation and will be crucial to improve the gravitational lensing mass maps of these structures and thus accurately characterize the properties of the first galaxies.

Wide Field Slitless Spectroscopy (WFSS) provides a powerful tool for detecting strong line emission in star-forming galaxies (SFGs) without the need for target preselection. As part of the GLASS-JWST Early Release Science (ERS) program, we leverage the near-infrared wavelength capabilities of NIRISS (1–2.2 μm) to observe rest-optical emission lines out to z ∼ 3.4, to a depth and with a spatial resolution higher than ever before (Hα to z < 2.4; [O iii]+Hβ to z < 3.4). In this Letter we constrain the rest-frame [O III]λ5007 equivalent width (EW) distribution for a sample of 76 1 < z < 3.4 SFGs in the A2744 Hubble Frontier Field and determine an abundance fraction of extreme emission line galaxies with EW > 750Å in our sample to be 12%. We determine a strong correlation between the measured Hβ and [O III]λ5007 EWs, supporting that the high [O III]λ5007 EW objects require massive stars in young stellar populations to generate the high-energy photons needed to doubly ionize oxygen. We extracted spectra for objects up to 2 mag fainter in the near-infrared than previous WFSS studies with the Hubble Space Telescope. Thus, this work clearly highlights the potential of JWST/NIRISS to provide high-quality WFSS data sets in crowded cluster environments.
Oocyte Donation: Three Perspectives
Authors: Chalova Leila , Lokshin Vyacheslav , Kiyan Vladimir , Turdaliyeva Botagoz , Zhybanisheva Karlygash , Kinzhibayev Arman
Published: December 2022

Background: A number of important problems remain unresolved in the field of assisted reproductive technologies (ART) using germ cells from a single donor. This study aimed to assess attitudes about the use of sex gamete donation in ART in different social groups including medical workers, oocyte recipients, and oocyte donors.
Methods: To achieve this goal, we surveyed 286 participants from seven countries. Of them, 190 were medical workers from ART clinics (respondents from seven countries), 45 were oocyte recipients (Kazakhstan), and 51 were oocyte donors (Kazakhstan).
Results: A survey of the three groups showed that issues related to donor health were most common in the donor selection process based on patient and doctor distrust of the health care system. The main motive for oocyte donation was financial compensation, which draws attention to the social disadvantage of the donor population. Medical workers with more than 5 years of work experience (79.7%) supported the use of programs tracking donor sex gametes and limiting the use of oocyte donors.
Conclusions: The willingness and consent of the surveyed medical workers and oocyte recipients to use the donor material and create a unified registry of donor sex gametes demonstrates the importance of this issue.

Published: December 2022

Cost information can help to improve the quality of medical care budgeting, and it can also improve the efficient allocation of resources and patient outcomes. The objective of this study was to estimate the inpatient unit cost of healthcare services in a secondary hospital in Saudi Arabia. A cross-sectional retrospective approach was applied to categorize the inpatients discharged from the hospital from January to December 2018. A top-down costing method for cost estimation was used. We found that the overhead cost center holds 40.17% of the total hospital cost, and intermediate and final care cost centers consumed 25.50% and 34.33%, respectively. Among inpatients wards, the Surgical ward had the highest operational cost (39.27%). Human resources consumed the hospital's highest resources (75%) on salaries. The hospital's cost structure was not remarkable and needs revolutionary changes to adopt the new payment mechanism envisioned in the 2030 Saudi vision.
Factors Related to Family Health Behavior in Samosir District: A Mix-Methods Study
Authors: Pakpahan Martina , Ayubi Dian
Published: December 2022

BACKGROUND: Non-communicable and communicable diseases remain a problem in Indonesia, where both are closely related to unhealthy behavior. Family health behavior affects the health status of the family and community.
AIM: The study aims to examine the factors related to family health behavior in the Samosir district.
METHODS: This study used a mixed-method approach with an explanatory sequential design. The respondents were 187 families who were selected through multi-stage random sampling. In-depth interviews were conducted with six informants: Samosir Health Department staff, Community Health Center staff, and religious or community leaders. The study was conducted in ten villages across three sub-districts. The instrument passed the validity and reliability tests and met triangulation. The Ethics Committee of the Faculty of Public Health, Universitas Indonesia has approved ethical clearance. Univariate and multivariate analysis with logistic regression (CI 95%) were used for quantitative data, while content analysis was used for qualitative data.
RESULTS: In Samosir District, family health behavior (consisting of eating vegetables and fruits, not smoking at home, washing hands with soap and water, and using clean water) was low (12.8 %). Attitudes, income, and the availability and affordability of health care facilities all have a significant correlation with family health behavior, according to multivariate analysis. In content analysis, attitudes, economy, community characteristics, infrastructure, and access were discovered to be related to family health behavior.
CONCLUSIONS: Health promotion strategies such as health education, community empowerment, and cross-sectoral collaboration must be thoroughly implemented to address the factors related to family health behavior because they can increase family health behavior through family empowerment.

BACKGROUND: COVID-19 peritraumatic distress index (CPDI) self-report questionnaire was designed to measure peritraumatic psychological distress in a pandemic emergency.

AIM: The aim of the study was the validation of Bulgarian COVID-19 peritraumatic distress index (CPDI) questionnaire and its application to measure psychological distress level in Bulgarian population.

METHODS: The study was conducted among 42 adults from February 2022 to March 2022. The average age of respondents participating in the validation of COVID-19 peritraumatic distress index (CPDI) questionnaire is 40.88 ± 13.309, women being predominant - 71.4% (n = 30), as well as individuals with higher education- 69% (n = 29). Following the preliminary instruction, all participants filled out the online Bulgarian version of the questionnaire anonymously 2 times within a period of 2 weeks. Data were analyzed using descriptive statistic, the Wilcoxon signed-rank test, Cronbach’s alpha, and Corrected Item-Total Correlation.

RESULTS: The CPDI instrument was linguistically validated according to a standard procedure (8) and cross-culturally adapted (9) into Bulgarian in several stages. The overall Cronbach’s alpha for the Peritraumatic Distress Index (CPDI) questionnaire is 0.940. Almost all corrected item-total correlations exceeded the accepted cut off of 0.30 indicating each item was related to the overall scale except for Q5 “I feel sympathetic to COVID-19 patients and their families.”

CONCLUSION: The Bulgarian version of the questionnaire reveals good reliability and cross-cultural validity and can be applied widely for measuring the prevalence of psychological suffering and distress in the pandemic emergency.

Authors: Hémar Éric
Published: December 2022

Si la logistique est devenue partie intégrante des enjeux économiques à venir sur de nombreux secteurs d’activité, son concept reste néanmoins mal connu. L’auteur souligne que, malgré d’indéniables atouts (foncier, emplois, infrastructures), la France accuse dans ce domaine un retard de compétitivité par rapport à ses voisins européens. Faire face à ces défis revient à devoir articuler les démarches suivantes : mettre en œuvre la transition énergétique, revisiter le schéma d’aménagement logistique et lutter contre une réglementation cumulative et contraignante.
La structuration des hinterlands portuaires - l’exemple de l’axe Seine
Authors: Sanjuan Pascal
Published: December 2022

La vallée de la Seine relie Paris à la mer par le grand port fluviomaritime HAROPA, issu de la fusion, en 2021, des ports du Havre, de Rouen et de Paris. Pour regagner des parts de marchés sur Anvers et Rotterdam, HAROPA doit développer l’espace terrestre qu’il approvisionne et dont il tire ses ressources, appelé hinterland. La structuration de son hinterland repose sur la qualité de la logistique et des infrastructures de transport pour charger, décharger et acheminer les marchandises. Elle tient aussi à sa capacité à accueillir des services et des activités génératrices de flux de marchandises. La structuration de l’hinterland d’HAROPA est également une politique publique partenariale majeure en vallée de la Seine, conduite par l’État, les collectivités territoriales et les gestionnaires publics d’infrastructures de transports. Elle vise à améliorer les infrastructures portuaires, fluviales et ferroviaires pour connecter la vallée de la Seine à des bassins d’activités de plus en plus éloignés. Elle vise également à implanter de nouvelles activités dans les zones portuaires. Les actions conduites résultent d’une stratégie partagée et soutenue par des moyens financiers significatifs, inscrits dans un contrat de plan interrégional conclu entre l’État et les régions Île-de-France et Normandie.

Santé publique France : un opérateur du ministère de la santé au service de l’État pour apporter la réponse logistique la plus adaptée aux besoins
Authors: Costaglioli Stéphane , Debeuret Christine
Published: December 2022

Santé publique France gère pour le compte de l’État les stocks stratégiques. Le schéma de stockage et de distribution initialement basé sur une plateforme nationale et des plateformes zonales, permettant une livraison rapide en tout point du territoire, est adapté en continu pour répondre aux besoins engendrés par les différentes alertes et crises sanitaires. La pandémie due à la Covid-19 a conduit à gérer une gamme de produits plus diversifiée et des volumes plus conséquents imposant une augmentation des capacités de stockage et de distribution. Les schémas de distribution ont également été impactés par les conditions de conservation des vaccins contre la Covid-19 et ont connu des évolutions permanentes pour élargir l’offre de vaccination et répondre aux attentes des professionnels de santé.

Une séparation impossible ? La passion amoureuse à l’adolescence
Authors: Bernateau Isée
Published: December 2022

À partir du cas d’une patiente vivant une passion amoureuse à l’adolescence, il s’agit de réfléchir sur les aléas et les entraves du processus de séparation à l’adolescence. L’investissement passionnel de l’objet apparaît comme une tentative de déplacement du lien aux objets œdipiens mais aussi comme une recherche de fusion symbiotique venant lutter contre les menaces de perte d’objet. Le lien passionnel cherche à réparer les carences dans le lien précoce à l’objet maternel mais la répétition est à l’œuvre, ramenant les angoisses de séparation caractéristiques d’un lien à l’objet insuffisamment contenant et sécurisant.

Seuls mais tous ensemble : ces mondes virtuels qui nous rapprochent et nous séparent
Authors: Blocquaux Stéphane
Published: December 2022

Omniprésents dans la plupart des foyers français, les écrans connectés modifient en profondeur les rapports interfamiliaux. S’il ne s’agit pas de remettre en question leurs qualités éducatives ou leur potentiel de divertissement, nous questionnerons le paradoxe inhérent à leur mode opératoire distancié comme source potentielle de séparation entre les membres d’un même foyer. Car si la connectivité numérique est souvent présentée, surtout par les industries qui la portent, comme un vecteur de renforcement des liens entre les humains, ne favoriseraient-elle pas, dans le même temps, une forme de « proximité fictive » en ce qui concerne les liens interfamiliaux ? Ne risque-t-elle pas de nuire aux nécessaires contacts physiques et à toutes les formes de communication non verbales présentes dans des médiations plus traditionnelles et plus directes ? Aussi, nous préconiserons autant un usage modéré des outils digitaux que l’urgente intensification de la prise en charge, au plus haut niveau politique, des questions liées à l’éducation au virtuel.
Polykystoses hépatiques
Authors: Bresson Hadni Solange
Published: December 2022

Les polykystoses hépatiques (PKH) regroupent différentes entités caractérisées par la présence dans le foie de plusieurs formations liquidiennes, au minimum 10, de type séreux, limitées par une assise unicellulaire de cellules cuboïdes ou cylindriques, analogue à l’épithélium biliaire mais ne communiquant pas avec les voies biliaires. L’architecture de l’arbre biliaire est ici préservée. On distingue les hamartomes biliaires ou complexes de Von Meyenburg qui correspondent à une malformation congénitale de la plaque ductale. Les trois autres affections sont des maladies génétiques affectant les canaux biliaires de taille moyenne. Il s’agit de la polykystose hépato- rénale (PKHR) autosomique récessive, affection pédiatrique et de deux affections se révélant à l’âge adulte, la polykystose hépato-rénale autosomique dominante (PKHRAD) et de la polykystose hépatique isolée (PKHI). Cette mise au point, principalement consacrée aux deux polykystoses génétiques de l’adulte, s’appuie sur les récentes recommandations de l’association européenne pour l’étude du foie (EASL) [1].

Objectif : Déterminer l’efficacité d’un programme structuré de gestion du stress avec la sophrologie Caycédienne sur les symptômes d’anxiété et de dépression chez les employés. Méthode : Étude prospective semi-contrôlée (N=224). Échelles psychométriques : Échelle d’anxiété et de dépression en milieu hospitalier (HAD) ; Inventaire d’état d’anxiété du Spielberger (STAI). Résultats : L’analyse intergroupes était statistiquement significative pour les échelles HAD et STAI-État (p<0,05) en faveur de la sophrologie. L’analyse intragroupe (N=207) a montré des diminutions significatives des sous-échelles HAD (p<0,001, TE=0,95 et 0,92) et STAI (p<0,001 ; TE=1,12 et 1,01). Les sous-groupes HAD- Anxiété (≤ 7 ;≥ 8≤ 10,≥ 11) ont montré des tailles d’effet plus fortes pour HAD-Anxiété et STAI lorsque les niveaux d’anxiété de base étaient plus élevés (TE=0,36 à 2,22). Les sous-groupes HAD -dépression (≤ 7 ; ≥ 8≤ 10, ≥ 11) ont montré des tailles d’effet plus fortes lorsque les niveaux de dépression de base étaient plus élevés (TE=0,83 à 3,51). Les résultats étaient indépendants du sexe et de l’âge. Aucun changement n’a été constaté pour le groupe contrôle (N=17). Conclusion : Un programme structuré de gestion du stress basé sur la sophrologie caycédienne est efficace pour réduire les symptômes d’anxiété et de dépression chez des groupes d’employés.
Souvarine et les spectres. La revue Le Contrat social (1957-1968)
Authors: Bordes François
Published: December 2022

De 1957 à 1968, Boris Souvarine dirigea et anima Le Contrat social. Revue historique et critique des faits et des idées. Cette importante publication constitua en France durant la Guerre froide l’un des relais de la soviétologie anglo-saxonne (Leonard Schapiro, Richard Pipes, Robert Conquest) et de la critique philosophique du totalitarisme soviétique (Raymond Aron, Kostas Papaïoannou, Karl Wittfogel). Cet article propose une anatomie de cette revue en présentant ses origines, les principaux thèmes abordés, les auteurs et collaborateurs « piliers » de la revue. Enfin, il étudie tout particulièrement la place de la critique du marxisme dans cette publication qui se donnait pour but de faire apparaître au grand jour la nature totalitaire d’un régime masqué sous le nom de communisme.
L’analyse des pratiques professionnelles, lieu symptôme de la conflictualité infiltrée dans le concept de « bonne distance »
Authors: Cauletin Michèle
Published: December 2022

La place qui a été donnée à l’analyse des pratiques professionnelle dans l’histoire des formations et dans l’évolution des référentiels d’intervention du champ social peut être considérée comme un des marqueurs de la plus ou moins grande prise en compte des facteurs subjectifs présents dans les relations d’aide. En repartant de la définition de ces espaces d’analyse des pratiques ou de supervision dans la construction des métiers historiques du social, en visitant quelques-unes des influences théoriques qui les ont nourris puis des cadres institutionnels qui les ont soutenus ou refusés, il s’agira de montrer combien la notion de « bonne distance » a pu se retrouver prise dans des représentations contrastées voire antagonistes.
Integrated review of the nexus between toxic elements in the environment and human health
Authors: Nieder Rolf , Benbi Dinesh K.
Published: December 2022

Emerging pollutants in the environment due to economic development have become a global challenge for environmental and human health management. Potentially toxic elements (PTEs), a major group of pollutants, have been detected in soil, air, water and food crops. Humans are exposed to PTEs through soil ingestion, consumption of water, uptake of food crop products originating from polluted fields, breathing of dust and fumes, and direct contact of the skin with contaminated soil and water. The dose absorbed by humans, the exposure route and the duration (i.e., acute or chronic) determine the toxicity of PTEs. Poisoning by PTEs can lead to excessive damage to health as a consequence of oxidative stress produced by the formation of free radicals and, as a consequence, to various disorders. The toxicity of certain organs includes neurotoxicity, nephrotoxicity, hepatotoxicity, skin toxicity, and cardiovascular toxicity. In the treatment of PTE toxicity, synthetic chelating agents and symptomatic supportive procedures have been conventionally used. In addition, there are new insights concerning natural products which may be a powerful option to treat several adverse consequences. Health policy implications need to include monitoring air, water, soil, food products, and individuals at risk, as well as environmental manipulation of soil, water, and sewage. The overall goal of this review is to present an integrated view of human exposure, risk assessment, clinical effects, as well as therapy, including new treatment options, related to highly toxic PTEs.
Inequality and income dynamics in Germany
Authors: Drechsel-Grau Moritz , Peichl Andreas , Schmid Kai D. , Schmieder Johannes F. , Walz Hannes , Wolter Stefanie
Published: December 2022

We provide a comprehensive analysis of income inequality and income dynamics for Germany over the last two decades. Combining personal income tax and social security data allows us—for the first time—to offer a complete picture of the distribution of annual earnings in Germany. We find that cross‐sectional inequality rose until 2009 for men and women. After the Great Recession, inequality continued to rise at a slower rate for men and fell slightly for women due to compression at the lower tail. We further document substantial gender differences in average earnings and inequality over the life cycle. While for men earnings rise and inequality falls as they grow older, many women reduce working hours when starting a family such that average earnings fall and inequality increases. Men's earnings changes are on average smaller than women's but are substantially more affected by the business cycle. During the Great Recession, men's earnings losses become magnified and gains are attenuated. Apart from recession years, earnings changes are significantly right‐skewed reflecting the good overall state of the German labor market and increasing labor supply. In the second part of the paper, we study the distribution of total income including incomes of self‐employed, business owners, and landlords. We find that total inequality increased significantly more than earnings inequality. Regarding income dynamics, entrepreneurs' income changes are more dispersed, less skewed, less leptokurtic, and less dependent on average past income than workers' income changes. Finally, we find that top income earners have become less likely to fall out of the top 1 and 0.1%.
Global trends in income inequality and income dynamics: New insights from GRID
Authors: Guvenen Fatih , Pistaferri Luigi , Violante Giovanni L.
Published: December 2022

The Global Repository of Income Dynamics (GRID) is a new open‐access, cross‐country database that contains a wide range of micro statistics on income inequality, dynamics, and mobility. It has four key characteristics: it is built on micro panel data drawn from administrative records; it fully exploits the longitudinal dimension of the underlying data sets; it offers granular descriptions of income inequality and income dynamics for finely defined subpopulations; and it is designed from the ground up with the goals of harmonization and cross‐country comparability. This paper introduces the database and presents a set of global trends in income inequality and income dynamics across the 13 countries that are currently in GRID. Our results are based on the statistics created for GRID by the 13 country teams who also contributed to this special issue with individual articles.
Producción y almacenaje de cereales en el noreste peninsular en época ibérica: algunos aspectos metodológicos y problemas de interpretación
Authors: González Vázquez Mateo
Published: December 2022

Las formas específicas que asume la producción y almacenaje de cereales son fundamentales en cualquier intento de definir la naturaleza de los sistemas agrarios y las dinámicas de cambio socioeconómico en las sociedades antiguas. En un área geográfica formada principalmente por la depresión litoral y las llanuras prelitorales de Cataluña, junto con el Languedoc occidental, las fosas de almacenaje o silos constituyen una de las estructuras arqueológicas más frecuentes de la Edad del Hierro. Su identificación responde a una mejor comprensión de las formas de ocupación y explotación del territorio, conocimiento que se ha beneficiado de la combinación de investigación científica y arqueología de urgencia en las últimas décadas. Este avance nos ha permitido obtener una imagen más completa y precisa de las estrategias de gestión y almacenamiento de los excedentes agrícolas, especialmente las relacionadas con los llamados “campos de silos”. La interpretación de la evidencia acumulada se basa principalmente en ciertos argumentos: una mayor complejidad social, un aumento de la producción agrícola (vinculada al desarrollo tecnológico) y la sedentarización. En este artículo, sugerimos la importancia de otros factores para comprender la expansión de las formas de almacenaje en silos desde una perspectiva transcultural y poscolonial, al mismo tiempo que señalamos algunos de los fundamentos epistemológicos y teóricos de las propuestas tradicionales: una lectura interesada por parte de agrónomos modernos de las fuentes antiguas. Primero, mostramos cómo este precedente ha influido en algunas de nuestras propias concepciones del almacenamiento en silos, particularmente en la mayoría de los estudios arqueológicos que se han centrado en la condición hermética de los silos, equiparando el almacenaje subterráneo con el almacenamiento en general. Partiendo de estas premisas, consideramos el papel del almacenaje en silos como un factor clave para comprender las estructuras económicas y la organización del paisaje de determinadas regiones ibéricas desde la Edad del Hierro hasta la colonización romana. Al mismo tiempo, analizamos la plausibilidad de las interpretaciones actuales sobre el significado social y económico de la prevalencia de este sistema de almacenaje en las sociedades ibéricas del noreste peninsular.

Problèmes de la musique moderne
Authors: Schlœzer Boris de , Scriabine Marine
Published: December 2022

Avec Problèmes de la musique moderne, les PUR poursuivent leur publication des œuvres de Boris de Schloezer (1881-1969), un des philosophes de la musique les plus importants du xxe siècle. Ce livre a été coécrit avec la musicologue Marina Scriabine (1911-1998), fille du compositeur russe Alexandre Scriabine (1872-1915) et nièce de Boris de Schloezer. Il s’agit du dernier livre théorique de Schloezer, et du seul qu’il ait écrit en collaboration. L’idée centrale du livre est que, depuis le Moyen Âge, les musiciens n’ont cessé d’accroître leur emprise sur leur matériau, le son. La fabrication du son par les appareils électroacoustiques est le tournant décisif de cette évolution ; la composition électronique est analysée comme l’accomplissement du désir de « maîtrise du son » déjà présent dans les musiques dodécaphonique puis sérielle. Paru en 1959, ce livre anticipe à bien des égards le sens général des transformations de la musique depuis un demi-siècle. « S’il faisait jusqu’à présent de la musique avec des sons, le musicien fait maintenant des sons avec de la musique » : par cette formule paradoxale, B. de Schloezer et M. Scriabine expriment la véritable révolution artistique et esthétique qu’ont connue, que connaissent encore, nombre des musiques d’aujourd’hui. La présente réédition contient la Postface écrite par Iannis Xenakis pour la réimpression du livre en 1977. Outre une introduction, cette réédition comporte également quatre articles importants de Boris de Schloezer.
Il était une fois le barrio El Libertador. De la construction de la maison à la formalisation d’un quartier précaire à Saint-Domingue (République dominicaine)
Authors: Sosa Valdez Darysleida
Published: December 2022

L’histoire des quartiers informels peut se lire à travers celle de la construction et la rénovation des maisons qui les composent. En retraçant les étapes de construction des habitations, cet article rend intelligible le processus de densification, de consolidation et de formalisation du barrio El Libertador, à Saint-Domingue, en République dominicaine. Trois récits, récoltés lors d’une enquête ethnographique menée entre 2016 et 2018 et traduits graphiquement permettent de comprendre les temporalités, les stratégies des habitants, les réseaux d’entraide et l’incidence des politiques urbaines sur l’histoire du barrio. L’analyse montre des changements structurels en termes physiques (espace construit) et sociaux qui se traduisent progressivement par l’homogénéisation et l’enfermement des modes d’habitat.
Au croisement des temporalités et des processus post-catastrophe : Canaan et le camp Corail
Authors: Lenoir Astrid
Published: December 2022

En Haïti, à la suite du séisme du 12 janvier 2010, un territoire peu habité au nord de Port-au-Prince a été retenu pour la construction du camp Corail. Constitué de deux secteurs, ce camp de logements provisoires a permis la relocalisation d’environ 10 000 personnes. Tout autour, la zone de Canaan s’est très vite constituée comme un véritable quartier d’habitations, par l’établissement spontané de dizaines de milliers de personnes. Rassemblées sur un même territoire, nous nous intéresserons à la manière dont se sont constituées ces deux entités (le camp Corail et Canaan) à travers l’analyse de l’action des différents acteurs, des pratiques, des discours et des représentations.
Residential Landscapes Sponsored by Companhia União Fabril (CUF) in Barreiro (1945-1972). Promotion of Multi-Family Working-Class Housing in Post-WWII Portugal
Authors: Milheiro Ana Vaz , Cardim João
Published: December 2022

This article deals with the promotion of housing for the working class in Portugal after World War II. The starting point of the research is the strategies followed by Companhia União Fabril (CUF) — a major Portuguese chemical company — between 1945 and 1972 in Barreiro, a town on the southern bank of the Tagus River, where the company had been gradually establishing its main factory grounds since the beginning of the twentieth century. The article argues that the publication of Law no. 2092 of April 9th 1958, which called upon welfare institutions to provide answers to the housing problem, was a fundamental step in the transformation of the Portuguese urban, suburban and rural environment, with massive consequences that historiography has yet to fully address.The article identifies the workers’ neighborhoods built by the company on factory grounds (1908-1946), comparing them to those that were later built on suburban farms (1951-1956), destined not only for the traditional working class, but also a growing middle-class that was emerging among the company’s staff. It then describes the operations that were carried out after the publication of the aforementioned law, between 1958 and 1967, and its repercussions up until the eve of the 1974 April Revolution. This law is essentially seen as positive, and had significant results in fighting the housing shortage issues of the time. However, we argue that it also shifted the housing provision responsibilities from private actors — in this case CUF — to public ones, leading to a fragmented urban landscape where the changes over the course of history — in terms of legislation, urban planning, architecture and social fabric — can be witnessed firsthand.
A Hybrid Learning Particle Swarm Optimization With Fuzzy Logic for Sentiment Classification Problems
Authors: Wang Jiyuan , Wang Kaiyue , Yan Xiangfang , Wang Chanjuan
Published: December 2022

Methods based on deep learning have great utility in the current field of sentiment classification. To better optimize the setting of hyper-parameters in deep learning, a hybrid learning particle swarm optimization with fuzzy logic (HLPSO-FL) is proposed in this paper. Hybrid learning strategies are divided into mainstream learning strategies and random learning strategies. The mainstream learning strategy is to define the mainstream particles in the cluster and build a scale-free network through the mainstream particles. The random learning strategy makes full use of historical information and speeds up the convergence of the algorithm. Furthermore, fuzzy logic is used to control algorithm parameters to balance algorithm exploration and exploration performance. HLPSO-FL has completed comparison experiments on benchmark functions and real sentiment classification problems respectively. The experimental results show that HLPSO-FL can effectively complete the hyperparameter optimization of sentiment classification problem in deep learning and has strong convergence.
Day surgery urolithiasis management: efficacy and safety of ureteroscopy and laser lithotripsy in a district general hospital setting
Authors: Balagobi B. , Butterworth W. , Lunawat R.
Published: December 2022

Introduction: Incidence of urolithiasis is rising worldwide and increasingly Ureteroscopy (URS) coupled with laser fragmentation is being used safely within the day surgery setting for ureteral and renal stone management. This study is to explore whether URS guided lithotripsy could be delivered effectively as a day surgery procedure.
Method: Retrospective analysis of 118 day surgery patients who underwent URS guided laser lithotripsy for ureteric and renal calculi between November 2017 and April 2019. All patients underwent ureteric stenting during acute admission prior to the URS guided lithotripsy. Outcomes were compared against European Association of Urology (EAU) guidelines on the best clinical practice in use of URS in urolithiasis.
Results: Of the 118 patients who underwent URS and laser fragmentation, mean age was 54 years with 2:1 male:female ratio. 56% were ureteric (67% upper, 8% middle and 25% distal ureter), 44% renal stones. Mean stone size was 9.7mm, with 58% ‹1cm, 38% 1-2cm and 4% ›2cm. 90.6% of patients following URS guided stone fragmentation were stone-free. The complication rate was 8.5% (n = 10), Clavien-dindo 3 in 4 patients and Clavien-dindo 4 in 1 patient.
Conclusion: This study demonstrated that URS guided stone fragmentation can safely deliver high stone free and low complication rates within day surgery setting.

Introduction and Objectives: Microwave ablation (MWA) is an emerging treatment modality for hepatocellular carcinoma (HCC) and other liver tumours. We aimed to assess the immediate success and complications of MWA in a cohort of patients.
Method: Patients were assessed retrospectively, using an intervieweradministered questionnaire and a follow-up CECT/MRI at 6-weeks.
Result: 55 patients underwent MWA from October 2021-May 2022, at Colombo-North Teaching Hospital, Ragama, Sri Lanka, and selected private hospitals( Durdans Hospital, Colombo, Nawaloka Hospital, Colombo, Lanka Hospital, Colombo).
The median age was 64 (40-82) years, with a male preponderance (n=45, 81.1%). The indication was HCC in 54 (98.1%) and metastatic tumour in one (1.8%). The median tumour size was 28 (10-80) mm. Segment VII was the commonest site to be involved (n=18, 34.6%). The majority (n=40, 72.7%) was a single lesion. No participant underwent the procedure twice. The mean post-procedural hospital stay was 12 hours (95%CI=11.4-12.5, SD=2.0).
In the 6-week follow-up, 2 recurrences (3.6%) and single death (1.8%) with no relation to the procedure, were reported. Another 2 (3.6%) denied the follow-up. Complete ablation was reported in 46 patients (83.7%), comparable to the rates in literature (95-97%), with only 7 patients (12.7%) having residual tumours. No major complications were reported. 9 patients (16.4%) developed 'Post ablation syndrome', not as common as in literature (34%). They presented with abdominal pain (7.3%), vomiting (7.3%), and fever (3.6%).
Conclusion: MWA is a successful and safe treatment option for primary liver tumours in Sri Lanka, with ablation rates comparable to the western world.
Prevalence, patterns, and risk factors of retinopathy of prematurity in a tertiary care multispecialty hospital in North Karnataka
Authors: Bhat Vishalakshi , Patil Shankargouda H. , Ashwini S.
Published: December 2022

Purpose:

The purpose of this study was to study the patterns, prevalence, and risk factors which contribute to the development of retinopathy of prematurity (ROP) in a tertiary care multispecialty hospital.

Materials and Methods:

This was a retrospective study from April 2019 to March 2021. All the infants screened at our hospital for ROP as per the Government of India “Rashtriya Bal Swasthya Karyakram” guidelines were included. Baseline characteristics, systemic risk factors, and ocular findings including ROP stages and zones involved were noted in the designated pro forma. Statistical analysis was done using SPSS version 25 software.

Results:

Of the 604 eyes of 302 infants screened, 27.8% had ROP. The mean gestational age (GA) and birth weight were 32+5 ± 2+1 weeks and 1.46 ± 0.39 kg, respectively. Among the 160 eyes with ROP, 44 eyes (27.5%) had Stage I ROP in Zone I, 57 eyes (35.6%) had Stage II ROP in Zone II, 17 eyes had Stage III (10.7%) ROP in Zone I and Zone II, and 42 eyes (26.25%) had aggressive posterior ROP (APROP). None had Stage IV or V ROP. GA <34 weeks, presence of blood transfusion, apnea, intraventricular hemorrhage (IVH), anemia, respiratory distress syndrome (RDS), and presence of two or more risk factors were positively associated with the development of ROP.

Conclusion:

The rate of ROP in our hospital is comparable to previously published data. A high rate of APROP was noted among the eyes developing ROP. Low GA and the presence of apnea, IVH, anemia, and RDS were associated with an increased chance of developing ROP.
Analysis of intrathecal clonidine as an adjuvant in the subarachnoid block on post-operative analgesia and safety profile in obstetric surgeries
Authors: Sujeer Swati , Kadni Reena Ravindra , Raja Leeberk , Zachariah Varghese K. , Pushpavathi Priya
Published: December 2022

Background:

Clonidine has long been considered an 'off-label' medication for use in obstetrics. Different doses of clonidine are studied and it is found that higher doses are associated with sedation and haemodynamic instability. Hence, we analysed a mini dose of intrathecal clonidine of 30 μg for its impact primarily on post-operative analgesia and secondarily on the quality of spinal anaesthesia, haemodynamics, sedation and neonatal outcomes in caesarean sections.

Methods:

One hundred participants were randomised them to receive the interventions. Group B received 11 mg of 0.5% hyperbaric bupivacaine (2.2 mL) and Group C received 10 mg of 0.5% hyperbaric bupivacaine with 30 μg of clonidine (2.2 mL). Motor, sensory and haemodynamic characteristics with time to rescue analgesics were observed in both the groups and analysed using univariate analysis.

Results:

Time to rescue analgesics (P < 0.001), visual analogue scores in the post-operative period and time to grade 0 Bromage (P = 0.002) were statistically significant in Group C. Time to T6 dermatomal level and time to grade 4 Bromage were similar in both the groups. Apgar scores were comparable and no adverse events were noted in both the groups.

Conclusions:

A low dose of intrathecal clonidine (30 μg) can prolong the duration of post-operative analgesia in caesarean section with comfortable maternal sedation and good neonatal outcome without significant complications.

Be careful before you exert: A case of renal hypouricaemia – Exercise-induced acute kidney injury
Authors: Khan Mohammed Fahad , Bhat Nithin , Hande Manjunath
Published: December 2022

A 21-year-old male came with complaints of abdominal pain, vomiting for 1 day following exertion in a 3000 m race. Routine laboratory investigations revealed deranged creatinine. However, serum uric acid (UA) levels were relatively normal. The patient was adequately hydrated, and input and output was monitored. His renal function tests were monitored daily and creatinine gradually normalised. The 24 h UA levels were done which was relatively normal, but the fractional excretion of UA was 220%. The patient gave a history of similar episode 3 years back which showed similar raised creatinine levels and normal UA. A diagnosis of idiopathic renal hypouricaemia precipitating exercise-induced acute kidney injury was made. The patient has been advised to avoid excessive exercise and asked to come for follow-up once yearly.
