In Islam, visiting graves reflects and reminds us of death and life in the Barzakh. The cemeteries must be adequately cared for and maintained since they play a significant role in the community as an important location for remembering and lamenting. However, remembering or finding the specific grave can sometimes be challenging. Thus, this project aims to develop a mobile application in which users can track their loved one’s grave to help them locate, save, and share the grave’s location by utilising the GPS sensors on the mobile phone. It is easier for them to track their loved ones and build a community for the Muslim cemetery community. The objectives of this project are to identify user requirements and to design and develop Pusara Finder – Muslim Grave Finder Mobile Application. This project uses the Android platform, and the mobile application has been developed using Visual Studio or Android Studio. There is a novelty of this project in which Pusara Finder is anl app designed to simplify the process of locating and navigating to Muslim graves in Shah Alam. This apps offers a seamless and intuitive experience, making it easier to pay tribute to the loved ones. The user also can access the complete database of Muslim graves with ease. The target user of this project was Muslim Public Users or people who want to find their specific grave. The methodology used for this project will be the Mobile Application Development Life Cycle (MADLC) Model. This project, however, has been developed up until the testing phase only. The project has been developed, and it’s in a prototype. In order to develop the mobile application, Flutter and Firebase has been implemented in this project. There were 11 users who had been involved in testing the usability of the mobile application by using System Usability Scale method with the score of 76.59 which in adjective rating is good.

Published: October 2024

Electronic and electrical waste (E-waste) has been identified as the fastest-growing waste stream in the world. In Malaysia, forecasts indicate that it will soon reach 24.5 million units of e-waste by the year 2025. Today, higher learning institutions also contribute to the rapidly growing threat of e-waste. Besides mobile phones, the usage of Information and Communication Technology (ICT) equipment at universities keeps increasing and contributes to the increased quantity of e-waste, while the handling and disposal methods of e-waste still need to be improved. The purpose of this paper is to examine the current e-waste management system as well as to investigate the critical challenges constraining e-waste management at public universities in Malaysia. By using a qualitative approach, a number of interview sessions have been conducted with the responsible departments at six established public universities in Malaysia. It has been found that currently only e-waste generated from used electric and electronic equipment (EEE) which have been declared as university assets are being managed by the responsible departments at the six universities. All six universities are using the standard process of handling their e-waste since every single process needs to comply with the requirements of the Ministry of Finance (MOF). This remains the main constraint to flexibility or improvement of the current system. The universities are also facing some challenges, among others, lack of awareness and knowledge on how to properly handle e-waste among university citizens, no clear sustainable policy at the university, lack of facilities within the university compound to support the proper practice of e-waste disposal as well as lack of education and related training provided to the campus citizens. This paper also provides some recommendations for the improvement of e-waste management towards sustainability and offers an agenda for future research.

Addressing Power Efficiency and Stability in SRAM: A 4x4 Cell Array Design with Enhanced Power Gating
Authors: Krishnakant Rai Santosh , Sahu Chandrahas
Published: October 2024

In order to lower power consumption and leakage currents during active operation, the suggested SRAM architecture with power gating design trims the source voltage across the SRAM cell, ranging from 50 to 150 mV. Power gating based on sectors is utilized, using a self-biasing approach where the gate terminal and source of a PMOS transistor act as a diode, controlling the virtual ground. However, three challenges arise with this method in nanometer technology: the additional self- biasing transistor (SBT) occupies 5% more space, the source voltage adjustment mechanisms are not effectively implemented, and the increase in virtual ground voltage leads to bias temperature instability. To implement this design, a 4x4 SRAM cell array is constructed, consisting of 4 rows and 4 columns of 10T SRAM cells. A decoder addresses these cells, and each row represents half a byte, with control circuitry managing input and output data. Additionally, the outputs of individual cells in each column are combined using a 4-bit OR, producing a single data output point. This architecture effectively reduces power consumption while maintaining operational efficiency, making it suitable for nanometer-scale SRAM designs.
Case Study- Ovarian Cyst
Authors: Priyadarshini P.
Published: October 2024

Fluid-filled sacs or pockets within or on the surface of an ovary are known as ovarian cysts. On either side of the uterus, women have two ovaries, each roughly the size and shape of an almond. Throughout the reproductive years, ova, or eggs, are released monthly in cycles after developing and maturing in the ovaries. Ovarian cysts affect a lot of women at some point. The majority of ovarian cysts are benign and cause little to no discomfort. Without therapy, the majority vanishes in a few of months. On the other hand, ovarian cysts, particularly those that have burst, might present with severe symptoms. Get routine pelvic exams and be aware of the symptoms that may indicate a potentially dangerous issue to safeguard your health.
Ending Sexual and Gender-Based Violence Against Women in the Tamale Metropolis: The Role of Religion
Authors: Fusheini Sanatu , Gedzi Victor Selorme , Owusu Ernest
Published: October 2024

This study examined the complex role religion plays in both promoting and ending sexual and gender-based violence against women in the Tamale Metropolis of Ghana. While major religious traditions emphasize equality and non-violence, certain interpretations of religious texts and cultural traditions have enabled patriarchal norms that subjugate women. Qualitative data from interviews with 18 respondents across Christian, Muslim, and traditional African religious communities revealed ongoing oppressive practices like forced marriage and early marriage of young girls, divorce, physical abuse such as wife battering, sexual abuse, and victim-blaming. However, religious institutions are increasingly initiating efforts to combat this violence through advocacy, education, counselling services, and partnerships with civil society groups. While these initiatives exist, significant challenges remain in transforming deeply entrenched sociocultural norms that enable violence against women. These initiatives demonstrate how religious institutions can leverage their moral authority to transform sociocultural norms enabling violence against women. The study highlights the need for sustained engagement with religious communities, reinterpretation of doctrine promoting gender equality, and collaborative efforts across sectors to eliminate this pervasive human rights issue. Harnessing the influential role of religion through a progressive, rights-based approach is crucial for addressing sexual and gender-based violence in the Tamale Metropolis and similar contexts. By delving into this intricate dynamic within the context of the Tamale Metropolis in Ghana, the study contributes to a deeper understanding of how religious beliefs, interpretations, and institutions can either perpetuate or combat this form of violence.

We present the atmospheric characterization of the substellar companion HD 19467 B as part of the pioneering James Webb Space Telescope Guaranteed Time Observer program to obtain moderate resolution spectra (R ∼ 2700, 3–5 μm) of a high-contrast companion with the NIRSpec integral field unit (IFU). HD 19467 B is an old, ∼9 Gyr, companion to a solar-type star with multiple measured dynamical masses. The spectra show detections of CO, CO2, CH4, and H2O. We forward model the spectra using Markov Chain Monte Carlo methods and atmospheric model grids to constrain the effective temperature and surface gravity. We then use NEWERA-PHOENIX grids to constrain nonequilibrium chemistry parameterized by K

Superfast rotators (SFRs) are small solar system objects that rotate faster than generally possible for a cohesionless rubble pile. Their rotational characteristics allow us to make inferences about their interior structure and composition. Here, we present the methods and results from a preliminary search for SFRs in the DECam Ecliptic Exploration Project (DEEP) data set. We find three SFRs from a sample of 686 main-belt asteroids, implying an occurrence rate of

%—a higher incidence rate than has been measured by previous studies. We suggest that this high occurrence rate is due to the small sub-kilometer size regime to which DEEP has access: the objects searched here were as small as ∼500 m. We compute the minimum required cohesive strength for each of these SFRs and discuss the implications of these strengths in the context of likely evolution mechanisms. We find that all three of these SFRs require strengths that are more than that of weak regolith but consistent with many cohesive asteroid strengths reported in the literature. Across the full DEEP data set, we have identified ∼70,000 Main-Belt Asteroids and expect ∼300 SFRs—a result that will be assessed in a future paper.
Characterization of the Western Pictor A Hotspot in Hard X-Rays with NuSTAR
Authors: Shaik Aamil , Meyer Eileen T. , Reddy Karthik , Laha Sibasish , Georganopoulos Markos
Published: October 2024

The origin of X-ray emission from the resolved kiloparsec-scale jets and hotspots of many active galactic nuclei remains uncertain, particularly where the X-ray emission is separate from the radio-optical synchrotron component. Possible explanations include synchrotron emission from a second electron population and external Compton or synchrotron self-Compton processes—alternatives which imply very different physical conditions within the jet. Until recently, X-ray studies of resolved jets and hotspots have been restricted to below ∼10 keV, often showing a hard spectral index indicating a spectral peak beyond this energy range. Here we present NuSTAR observations of the nearby powerful radio galaxy Pictor A, in which we clearly detect the western hotspot at approximately 4′ from the host galaxy, the most significant detection of hotspot emission above 10 keV to date. The NuSTAR spectrum is best fit by a single power law of index Γ = 2.03 ± 0.04; an exponential cutoff gives a 1σ lower limit on the cutoff energy of 40.7 keV. We confirm previous findings of variations in the soft X-ray flux detected by Chandra over the 2000 to 2015 period, at a significance of 6.5σ. This rises to >8σ in the common 3–8 keV band using the combined 22 yr span of Chandra and NuSTAR observations. The variability of the western Pictor A hotspot strongly confirms the previously argued synchrotron nature of the X-ray emission for the hotspot, while the lower bound to the spectral cutoff energy implies electron energies in the hotspot reach up to at least a few TeV.

We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of the binary Class 0 protostellar system BHR 71 IRS1 and IRS2 as part of the Early Planet Formation in Embedded Disks (eDisk) ALMA Large Program. We describe the 12CO (J = 2–1), 13CO (J = 2–1), C18O (J = 2–1), H2CO (J = 32,1–22,0), and SiO (J = 5–4) molecular lines along with the 1.3 mm continuum at high spatial resolution (∼0.″08 or ∼5 au). Dust continuum emission is detected toward BHR 71 IRS1 and IRS2, with a central compact component and extended continuum emission. The compact components are smooth and show no sign of substructures such as spirals, rings, or gaps. However, there is a brightness asymmetry along the minor axis of the presumed disk in IRS1, possibly indicative of an inclined geometrically and optically thick disk-like component. Using a position–velocity diagram analysis of the C18O line, clear Keplerian motions were not detected toward either source. If Keplerian rotationally supported disks are present, they are likely deeply embedded in their envelope. However, we can set upper limits of the central protostellar mass of 0.46 M
⊙ and 0.26 M
⊙ for BHR 71 IRS1 and BHR 71 IRS2, respectively. Outflows traced by 12CO and SiO are detected in both sources. The outflows can be divided into two components, a wide-angle outflow and a jet. In IRS1, the jet exhibits a double helical structure, reflecting the removal of angular momentum from the system. In IRS2, the jet is very collimated and shows a chain of knots, suggesting episodic accretion events.
Cosmic-Ray Feedback on Bistable Interstellar Medium Turbulence
Authors: Habegger Roark , Ho Ka Wai , Yuen Ka Ho , Zweibel Ellen G.
Published: October 2024

While cosmic rays (E ≳ 1 GeV) are well coupled to a galaxy’s interstellar medium (ISM) at scales of L > 100 pc, adjusting stratification and driving outflows, their impact on small scales is less clear. Based on calculations of the cosmic-ray diffusion coefficient from observations of the grammage in the Milky Way, cosmic rays have little time to dynamically impact the ISM on those small scales. Using numerical simulations, we explore how more complex cosmic-ray transport could allow cosmic rays to couple to the ISM on small scales. We create a two-zone model of cosmic-ray transport, with the cosmic-ray diffusion coefficient set at the estimated Milky Way value in cold gas but smaller in warm gas. We compare this model to simulations with a constant diffusion coefficient. Quicker diffusion through cold gas allows more cold gas to form compared to a simulation with a constant, small diffusion coefficient. However, slower diffusion in warm gas allows cosmic rays to take energy from the turbulent cascade anisotropically. This cosmic-ray energization comes at the expense of turbulent energy which would otherwise be lost during radiative cooling. Finally, we show our two-zone model is capable of matching observational estimates of the grammage for some transport paths through the simulation.

We present a detailed model atmosphere analysis of massive white dwarfs with M > 0.9 M
⊙ and T
eff ≥ 11,000 K in the Montreal White Dwarf Database 100 pc sample and the Pan-STARRS footprint. We obtained follow-up optical spectroscopy of 109 objects with no previous spectral classification in the literature. Our spectroscopic follow-up is now complete for all 204 objects in the sample. We find 118 normal DA white dwarfs, including 45 massive DAs near the ZZ Ceti instability strip. There are no normal massive DBs: the six DBs in the sample are strongly magnetic and/or rapidly rotating. There are 20 massive DQ white dwarfs in our sample, and all are found in the crystallization sequence. In addition, 66 targets are magnetic (32% of the sample). We use magnetic white dwarf atmosphere models to constrain the field strength and geometry using offset dipole models. We also use magnetism, kinematics, and rotation measurements to constrain the fraction of merger remnant candidates among this population. The merger fraction of this sample increases from 25% for 0.9–1 M

Previous works have demonstrated that 5%–9% of high-mass white dwarfs stop cooling for ∼8 Gyr due to the 22Ne distillation process, which leads to an overdensity of Q-branch stars in the solar neighborhood. We demonstrate that the overabundance of the merger remnant candidates in our sample is likely due to the same process.
Observational Test of f(Q) Gravity with Weak Gravitational Lensing
Authors: Wang Qingqing , Ren Xin , Cai Yi-Fu , Luo Wentao , Saridakis Emmanuel N.
Published: October 2024

In this article we confront a class of f(Q) gravity models with observational data of galaxy–galaxy lensing. Specifically, we consider f(Q) gravity models containing a small quadratic correction when compared with general relativity (GR), and quantify this correction by a model parameter, α. To derive the observational constraints, we start by extracting spherically symmetric solutions, which correspond to deviations from the Schwarzschild solution that depends on the model parameters in a twofold way, i.e., a renormalized mass and a new term proportional to r
−2. Then, we calculate the effective lensing potential, the deflection angle, the shear component, and the effective excess surface density profile. After that, we employ a group catalog and a shape catalog from the Sloan Digital Sky Survey Data Release 7 for the lens and source samples, respectively. Moreover, we handle the off-center radius as a free parameter and constrain it using a Markov Chain Monte Carlo method. Concerning the deviation parameter from GR we derive

Our results indicate that the f(Q) corrections alongside the off-center effect yield a scenario that is slightly favored.
The Role of Meridional Flow in the Generation of Solar/Stellar Magnetic Fields and Cycles
Authors: Vashishth Vindya , Karak Bidya Binay
Published: October 2024

Meridional flow is crucial in generating the solar poloidal magnetic field by facilitating poleward transport of the field from decayed bipolar magnetic regions (BMRs). As the meridional circulation changes with the stellar rotation rate, the properties of stellar magnetic cycles are expected to be influenced by this flow. In this study, we explore the role of meridional flow in generating magnetic fields in the Sun and Sun-like stars using the STABLE (surface flux transport and Babcock–Leighton) dynamo model. We find that a moderate meridional flow increases the polar field by efficiently driving the trailing polarity flux toward the pole, while a strong flow tends to transport both polarities of BMRs poleward, potentially reducing the polar field. Our findings are in perfect agreement with what one can expect from the surface flux transport model. Similarly, the toroidal field initially increases with moderate flow speeds and then decreases beyond a certain value. This trend is due to the competitive effects of shearing and diffusion. Furthermore, our study highlights the impact of meridional flow on the strength and duration of stellar cycles. By including the meridional flow from a mean-field hydrodynamics model in STABLE, we show that the magnetic field strength initially increases with the stellar rotation rate and then declines in rapidly rotating stars, offering an explanation of the observed variation of stellar magnetic field with rotation rate.

Published: October 2024

The Amazon biome is home to the largest tropical forest on the planet and has the greatest global biodiversity on Earth. Despite this, several less charismatic taxonomic groups, such as amphibians, lack comprehensive studies on their species richness and spatial distribution in the Amazon Region. In this study, we investigated: i) patterns of richness and endemism of Amazonian amphibians across geopolitical and biogeographic divisions, ii) similarities between different Amazonian bioregions, iii) temporal trends in amphibian sampling, iv) conservation status of amphibians according to assessments of the IUCN and v) the importance of diverse data sources in building a robust database of amphibian occurrences. We aggregated data from four different sources: publicly accessible platforms, peer-reviewed articles, grey literature and fieldwork inventories spanning 15 years (2007–2021), ultimately compiling 160,643 records of 947 species across 7,418 sampled sites. The greatest diversity of species was found in Peru, Brazil and Ecuador, with notable amphibian diversity and endemism in regions such as the western basins and the Tapajós River Basin in the central-southern Amazon. Geographical analysis of species diversity revealed four distinct groups defined by latitudinal (the Amazon River) and longitudinal (the Juruá, Madeira and Tapajós Rivers) gradients, with low species similarity (< 40%), particularly in the basins of north-western Amazonia. Amphibian sampling in the Amazon has intensified since the 1950s with the establishment of important research centres such as INPA and the GOELD Museum in the Brazilian Amazon. Approximately 18% of Amazonian amphibian species face extinction risk, according to IUCN assessments, highlighting the need for comprehensive data sources to understand and conserve species in this megadiverse region. Our findings suggest that river systems likely influence Amazonian amphibian species composition due to biogeographic history, emphasising the need for robust taxonomic and spatial databases. This study, therefore, contributes a valuable large-scale dataset for Amazonian amphibians, guiding future research and strategies for amphibian conservation.

The male of L. soboutii is described for the first time. Diagnostic drawings of preserved specimens and first photos of several preserved and alive species are provided along with the detailed collecting data.
Status inequality and status hierarchies
Authors: Accominotti Fabien
Published: October 2024

Le statut – la valeur accordée aux individus par autrui – est une dimension fondamentale de la stratification sociale. Il existe cependant une ambiguïté quant à ce que les sociologues entendent par différences de statut : s’agit-il de différences dans la quantité globale d’estime que les individus reçoivent d’autrui, ou dans la manière dont ils répartissent leur estime entre divers autres ? À partir de cette distinction, cet article propose d’organiser la recherche récente sur le statut en deux grandes approches : la première étudie l’inégalité de statut, ou l’inégalité dans la somme d’estime ou de respect que différents acteurs reçoivent des autres ; la seconde étudie les hiérarchies de statut, ou les relations de supériorité, d’égalité, et d’infériorité de valeur que chacun perçoit entre les autres. Passant en revue des travaux sur les hiérarchies raciales, professionnelles, de genre, ou sur la dynamique des petits groupes, je montre que l’inégalité de statut est un phénomène structurel dont on cherche généralement à expliquer l’intensité, tandis que les hiérarchies de statut sont des schémas culturels dont on peut examiner le contenu, la forme, le caractère plus ou moins partagé, et les modes d’acquisition, qu’il s’agisse de hiérarchies spécifiques ou d’un œil hiérarchique plus générique porté sur le monde social.

De quelles façons les faire parler sur des sujets parfois difficiles ou traumatiques tout en essayant de protéger leur estime de soi ? Comment articuler les exigences de transparence avec l’impératif de confidentialité ? La méthode de l’enquête par entretiens suscite des réflexions éthiques spécifiques que l’article met en évidence, enrichissant ainsi les réflexions sur l’éthique en pratique.
Haro sur le Sud : la nouvelle direction de l’UAW tente d’engranger les fruits de sa victoire contractuelle de 2023
Authors: Sauviat Catherine
Published: October 2024

Après sa victoire obtenue lors du renouvellement de la convention collective des Big Three de l’automobile, l’UAW a décidé de s’engager dans une vaste campagne de syndicalisation des constructeurs étrangers, installés dans le Sud des États-Unis, un quasi-désert syndical. Cette offensive s’est jusqu’à présent soldée par une victoire chez Volkswagen suivie par une défaite chez Mercedes-Benz. L’enjeu de la syndicalisation du Sud étasunien est vital pour le syndicat de l’automobile. Toutefois, l’enquête en cours diligentée par le contrôleur indépendant nommé suite à la corruption avérée de certains de ses plus hauts dirigeants pourrait avoir des conséquences dommageables pour le syndicat et son nouveau président, Shawn Fain.
Représentations sociales des enseignants sur la scolarisation des enfants en situation de handicap au Burundi

Published: October 2024

Cet article s’attache à comprendre les représentations sociales des enseignants des écoles ordinaires à propos de la scolarisation des enfants en situation de handicap. Nous sommes partis de cette question : comment les enseignants des écoles ordinaires se représentent-ils la scolarisation des ESH dans le milieu éducatif burundais ? L’étude a été menée auprès de 138 enseignants ordinaires dont 53,6 % de femmes. Les données collectées par questionnaire ont été traitées sous SPSS. Les résultats montrent que les enseignants sans formation ni expérience expriment des représentations défavorables à l’accueil des enfants en situation de handicap dans le milieu ordinaire. La majorité d’entre eux expriment des représentations discriminatoires qui les conduisent à considérer la déficience mentale, la déficience visuelle, le polyhandicap ainsi que la déficience auditive comme des catégories de handicap à exclure du milieu ordinaire.
Apprendre à enseigner. Un défi pour l’enseignement et la recherche
Authors: Maccario Daniela
Published: October 2024

L’article présente le parcours et quelques résultats relatifs à un dispositif innovant de formation des futurs enseignants de l’école primaire dans le domaine de la gestion de la classe, incluant la gestion, vidéo-documentation et vidéo-analyse d’une leçon en situation naturelle. L’analyse des schémas d’interaction récurrents énoncés par les étudiants dans des fiches d’auto-analyse laisse supposer que le dispositif formatif adopté peut favoriser l’appropriation phénoménologique et opérationnelle de schémas d’interaction didactique potentiellement inclusifs ; néanmoins, une analyse externe des vidéos montre qu’il y a des zones diffuses d’exigence formative à surveiller qui méritent un approfondissement ultérieur et une base plus large de connaissances empirique.
Une tentative de mise en œuvre d’un dispositif inclusif dans le second degré
Authors: Le Bec Marie
Published: October 2024

Ce témoignage décrit un projet engagé, entre 2020 et 2023, par une professeure de français en collège, qui, confrontée à la difficulté d’enseigner dans une classe de 6 e du fait d’une dizaine d’élèves dont les difficultés d’apprentissage perturbaient l’avancée du groupe entier, s’est interrogée sur les moyens de surmonter le sentiment de désarroi et d’impuissance qu’elle éprouvait dans cette situation. Orientée par l’inspectrice vers la lecture de Boimare et dirigée par son chef d’établissement vers le laboratoire LACES de l’université de Bordeaux, elle obtient à la fois le soutien de l’unité de recherche et celui de la Cellule académique recherche développement innovation et expérimentation (Cardie) du rectorat de Bordeaux pour créer l’atelier intitulé Conversons ! Ce dispositif, initialement animé par six enseignants, est destiné à accompagner des enfants en vulnérabilité scolaire dans le but de restaurer leur estime de soi en les réconciliant avec leur capacité de s’engager dans les apprentissages. Le moyen choisi est le développement des compétences psycho-sociales en petits groupes de cinq à dix élèves. Cette tentative de promouvoir une forme de mobilité institutionnelle d’inspiration inclusive au sein d’un collège, dont l’effet est de déplacer l’ordre établi des prérogatives professionnelles des enseignants, se heurte aux rigidités normatives et organisationnelles du collège. La prégnance de l’enseignement disciplinaire et de l’évaluation chiffrée relègue au second plan la prévention du décrochage et le bien-être des élèves. La possibilité offerte aux professeurs engagés dans de nouvelles formes de rencontres avec leurs élèves, ailleurs que dans la classe entière, est finalement abandonnée au regard des contraintes d’emploi du temps et du coût en heures supplémentaires.
Expérience scolaire des élèves déficients moteurs en milieu inclusif
Authors: Akiki Joumana
Published: October 2024

Notre recherche porte sur l’expérience scolaire de 13 élèves porteurs d’une déficience motrice, âgés de 6 à 16 ans et scolarisés dans une école inclusive. Le test du dessin de l’école a servi de médiateur favorisant la parole et l’expression verbale. L’école dessinée montre un environnement physique, sans présence humaine. L’analyse de contenu des entretiens révèle des perceptions à la fois positives et négatives de cette expérience scolaire. L’école n’est pas perçue comme différente de toute autre école. Les relations aux pairs sont abordées par les participants sous deux aspects ambivalents : harcèlement et rejet, d’une part, amitiés, entraide et soutien, de l’autre. La dimension sociale semble constituer un élément de base au niveau des représentations de l’école chez les élèves déficients moteurs.
Discriminations à l’embauche des Ultramarins : un testing en outre-mer et dans l’Hexagone
Authors: Chareyron Sylvain , Anne Denis , L’Horty Yannick , Peyrière Rebecca
Published: October 2024

Cette étude exploite le premier test de discrimination réalisé dans les départements français d’outre-mer. L’article mesure l’ampleur des discriminations dans l’accès à l’emploi pour les personnes d’origine ultramarine et simultanément pour celles qui résident dans un quartier prioritaire de la politique de la ville. En mai 2021, trois candidats fictifs ont candidaté pour des postes de serveur auprès de 921 restaurants sur quatre territoires, en Guadeloupe, en Martinique, à La Réunion et à Paris. Globalement, nous n’observons pas de discrimination significative selon une adresse dans un quartier prioritaire. En revanche, les candidats d’origine ultramarine sont discriminés par rapport au candidat d’origine métropolitaine. La discrimination n’est pas spécifique à l’Hexagone et apparaît également dans les départements d’outre-mer.
Analyse du lien entre mixité du genre ou de l’âge et productivité des entreprises aux Antilles
Authors: Salibekyan-Rosain Zinaïda , Bilionière Maurice , Louis Jean , Mathouraparsad Sébastien
Published: October 2024

Le marché du travail antillais s’est profondément modifié en deux décennies, avec une présence accrue des femmes et des seniors. Pour la première fois aux Antilles françaises, nous avons mobilisé les données FARE-DADS (2014-2015) avec l’objectif d’analyser le lien entre mixité de genre ou de l’âge et productivité des entreprises. À partir de trois approches de la diversité, nous avons pu montrer que la mixité en termes de genre ou d’âge est associée à une meilleure productivité du travail. Néanmoins, les résultats sectoriels pour la mixité en termes d’âge sont plus mitigés. Ceci peut s’expliquer par le manque de complémentarité des compétences observé parmi les seniors sur ces petits territoires.
Reni y España: a propósito de dos exposiciones recientes
Authors: Navarrete Prieto Benito
Published: October 2024

Las exposiciones dedicadas a Guido Reni en el Städel Museum de Frankfort y el Museo del Prado han brindado la ocasión de revisar la producción del pintor boloñés con aproximaciones diferenciadas y complementarias. Este artículo analiza críticamente la segunda y presenta la versión del Santiago el Mayor conservada en el museo del Prado como una copia debida a Francisco de Zurbarán estudiando el original de Reni hoy en el Museo de Houston cuando se encontraba en la Cartuja de las Cuevas de Sevilla integrando el apostolado del panteón familiar que el III duque de Alcalá había encargado a diferentes pintores italianos.

A agenesia pulmonar unilateral é uma anomalia rara que pode passar despercebida, na ausência de intercorrências clínicas durante a vida do paciente, podendo ser inicialmente mal diagnosticada e confundida com outras patologias. A associação desta malformação com outras ipsilaterais resulta em um quadro ainda mais raro, com poucas descrições na literatura
