Analisis Framing Kompas. Com Dan Tempo.Co Pada Pemberitaan All Eyes On Papua Periode 31 Mei-22 Juni 2024
Authors: Resti Rahmawati  , Ilham Gemiharto  , Samson CMS
Published: February 2025

The All Eyes on Papua movement has shocked the Indonesian people, because it turns out that there is an important problem behind the movement. This problem is the seizure of the customary forests of the Awyu and Moi tribes in Papua which will be turned into oil palm plantations. This research analyzes the framing of Kompas.com and Tempo.co online media regarding the issue of “All Eyes on Papua” in the period from 31 May to 22 June 2024. Using a qualitative method, this research explores how the two media framed the issue through analyzing relevant articles. The results show that Kompas.com emphasized humanitarian aspects and environmental impacts, while Tempo.co focused more on criticism of government policies and protection of indigenous peoples' rights. Kompas.com defined All Eyes on Papua, as an environmental and development issue, while Tempo.co tends to see it as a political and humanitarian issue. Kompas.com sees the cause of this problem as the government's lack of attention to balance and the rights of indigenous peoples, while Temp.co considers that this happened because the government issued a feasibility permit without FPIC. The moral consideration given by Kompas.com is that the government should respect the rights of the community and return their land, while Tempo.co considers that the government does not respect the rights of indigenous peoples. The problem solving offered by Kompas.com is that the government involves indigenous peoples and is processing the return of customary land, while Tempo.co that the government should change policies that can protect customary forests. This research recommends that the media be more diverse in presenting perspectives and providing space for indigenous voices in the news.

Published: February 2025

Unplanned purchase decisions triggered by the fear of missing out on fashion is an actual phenomenon that takes place massively among young people. This study aims to explore the influence of FoMO on Gen Z's consumptive behavior. FoMO is defined as the fear of missing out on a pleasurable experience, which can drive individuals to engage in buying viral products to avoid feeling left behind or isolated from popular trends. Through a qualitative approach with a descriptive analysis method, the results of this study's analysis show that FoMO has a significant influence on Gen Z's consumptive behavior as an important entity of viral product buyers on social media. The government has considered Gen Z (through the growth of the e-commerce and marketplace) as an important entity in supporting marketers and entrepreneurs to utilize FoMO as an important variable that influences Gen Z's impulse purchase decisions. For this reason, a more in-depth study of the relationship between FoMO and Gen Z's consumptive behavior can be an entry point to increase the effectiveness of viral product marketing in the current digital era.

Which rocky exoplanets have atmospheres? This presumably simple question is the first that must be answered to understand the prevalence of nearby habitable planets. A mere 6.9 pc from Earth, LTT 1445A is the closest transiting M dwarf system, and its largest known planet, at 1.31 R⊕ and 424 K, is one of the most promising targets in which to search for an atmosphere. We use Hubble Space Telescope/Wide Field Camera 3 transmission spectroscopy with the G280 and G141 grisms to study the spectrum of LTT 1445Ab between 0.2 and 1.65 μm. In doing so, we uncover an ultraviolet (UV) flare on the neighboring star LTT 1445C that is completely invisible at optical wavelengths; we report one of the first simultaneous near-UV/optical spectra of an M dwarf flare. The planet spectrum is consistent with a flat line (with median transit depth uncertainties of 128 and 52 ppm for the G280 and G141 observations, respectively), though the infrared (IR) portion displays potential features that could be explained by known opacity sources such as HCN. Some atmospheric retrievals weakly favor (∼2σ) an atmosphere, but it remains challenging to discern between stellar contamination, an atmosphere, and a featureless spectrum at this time. We do, however, confidently rule out ≤100× solar metallicity atmospheres. Although stellar contamination retrievals cannot fit the IR features well, the overall spectrum is consistent with stellar contamination from hot or cold spots. Based on the UV/optical data, we place limits on the extent of stellar variability expected in the near-IR (30–40 ppm), which will be critical for future James Webb Space Telescope observations.

Published: February 2025

In the era of a data-driven landscape, the development of an efficient and interpretable method has become a pivotal tool for robustly identifying memberships of clusters. We present a novel cluster finder approach called forest fire clustering (FFC). FFC combines iterative label propagation with parallel Monte Carlo simulation to achieve internal validation of clustering results. We use a Gaia DR3 catalog comprising 322 random objects with distinct heliocentric distances from approximately 0 to 5 kpc, along with one ultrafaint dwarf galaxy Bootes I (∼63 kpc), as our validation sample. We compare the performance of FFC with that of DBSCAN and HDBSCAN on this data set by configuring them into the same processing pipeline for identifying star members. Our results indicate that FFC outperforms the two others in terms of the quality of clusters, particularly for clusters located at distances greater than 2 kpc. Additionally, FFC demonstrates robust performance and efficiency. Based on the high-quality clusters derived from FFC, we provide a detailed analysis of cluster properties. We determine various cluster parameters, including age, mass, [Fe/H], distance modulus, reddening, and binary fraction. Furthermore, dynamic properties are reliably estimated through the fitting of radial density profiles and theoretical models. This study suggests that FFC is a suitable tool for identifying reliable memberships of stellar systems, highlighting the discovery of more distant clusters and enabling the identification of high-quality clusters to accurately uncover cluster properties.
A Search for Radio Millisecond Pulsar Companions around Extremely Low-mass White Dwarfs with Ellipsoidal Variability
Authors: Huang W. J. , Tam Pak-Hin Thomas , Ren L. L. , Lin J. M.
Published: February 2025

Extremely low-mass (ELM) white dwarfs (WDs) are helium-core WDs with masses less than 0.3 M
⊙. Short-period ELM WD binaries that exhibit ellipsoidal variations may harbor heavier companions, either massive WDs or millisecond pulsars (MSPs). In this study, we selected ∼12,000 ELM WDs or their candidates, and searched for ellipsoidal-like lightcurves with orbital periods shorter than 1 day, by using the public data from Zwicky Transient Facility. Finally, 23 such systems were found, with 17 being newly discovered. We selected nine high-priority targets likely to evolve from the Roche lobe overflow channel and estimated their companion masses from the extracted ellipsoidal variation amplitude. Among them, four targets have companion masses exceeding 1 M
⊙. We performed a search for radio pulsations from six of these targets by using Five-hundred-meter Aperture Spherical radio Telescope. However, no convincing radio pulse signals were found, resulting in upper limits for the radio flux at around 8 μJy. Given the nondetection of radio pulsations from a total of 11 similar systems, the fraction of ellipsoidal ELM WDs around MSPs is estimated to be below 15

We present Atacama Large Millimeter/submillimeter Array Band 6 (1.3 mm) observations of dense cores in three massive molecular clouds within the central molecular zone (CMZ) of the Milky Way, including the Dust Ridge cloud e, Sgr C, and the 20 km s−1 cloud, at a spatial resolution of 2000 au. Among the 834 cores identified from the 1.3 mm continuum, we constrain temperatures and linewidths of 253 cores using local thermodynamic equilibrium methods to fit the H2CO and/or CH3CN spectra. We determine their masses using the 1.3 mm dust continuum and derived temperatures, and then evaluate their virial parameters using the H2CO and/or CH3CN linewidths and construct the core mass functions (CMFs). We find that the contribution of external pressure is crucial for the virial equilibrium of the dense cores in the three clouds, which contrasts with the environment in the Galactic disk where dense cores are already bound, even without the contribution of external pressure. With our new temperature estimates we also find that the CMFs show a Salpeter-like slope in the high-mass (≳3–6 M
⊙) end, a change from previous works. Combined with the possible top-heavy initial mass functions (IMFs) in the CMZ, our result suggests that gas accretion and further fragmentation may play important roles in transforming the CMF to the IMF.

The observation of the kilonova AT2017gfo and investigations of its light curves and spectra confirmed that neutron star mergers are sites of r-process nucleosynthesis. However, the identification of elements responsible for the spectral features is still challenging, particularly at the near-infrared wavelengths. In this study, we systematically searched for all possible near-infrared transitions of heavy elements using experimentally calibrated energy levels. Our analysis reveals that most candidate elements with strong absorption lines are lanthanides (Z = 57–71) and actinides (Z = 89–103). This is due to their complex structures leading to many low-lying energy levels, which results in strong transitions in the near-infrared range. N. Domoto et al. (2022) have shown that La iii and Ce iii can explain the absorption features at λ ∼ 12000–15000 Å. While our results confirm that these two elements show strong infrared features, we additionally identify Gd iii as the next most promising species. Due to its unique atomic structure involving the half-filled 4f and the outer 5d orbitals, Gd iii has one of the lowest-lying energy levels, between which relatively strong transitions occur. We also find absorption lines caused by Gd iii in the near-infrared spectrum of a chemically peculiar star HR 465, which supports their emergence in kilonova spectra. By performing radiative transfer simulations, we confirm that Gd iii lines affect the feature at ∼12000 Å previously attributed to La iii. Future space-based time-series observations of kilonova spectra will allow the identification of Gd iii lines.

Published: February 2025

The Aeos project introduces a series of high-resolution cosmological simulations that model star-by-star chemical enrichment and galaxy formation in the early Universe, achieving 1 pc resolution. These simulations capture the complexities of galaxy evolution within the first ~300 Myr by modeling individual stars and their feedback processes. By incorporating chemical yields from individual stars, Aeos generates galaxies with diverse stellar chemical abundances, linking them to hierarchical galaxy formation and early nucleosynthetic events. These simulations underscore the importance of chemical abundance patterns in ancient stars as vital probes of early nucleosynthesis, star formation histories, and galaxy formation. We examine the metallicity floors of various elements resulting from Population III enrichment, providing best-fit values for eight different metals (e.g., [O/H] = −4.0) to guide simulations without Population III models. Additionally, we identify galaxies that begin star formation with Population II after external enrichment and investigate the frequency of carbon-enhanced metal-poor stars at varying metallicities. The Aeos simulations offer detailed insights into the relationship between star formation, feedback, and chemical enrichment. Future work will extend these simulations to later epochs to interpret the diverse stellar populations of the Milky Way and its satellites.
Little Red Dots: Rapidly Growing Black Holes Reddened by Extended Dusty Flows
Authors: Li Zhengrong , Inayoshi Kohei , Chen Kejian , Ichikawa Kohei , Ho Luis C.
Published: February 2025

The James Webb Space Telescope (JWST) observations have revolutionized extragalactic research, particularly with the discovery of little red dots (LRDs), which have been discovered as a population of dust-reddened broad-line active galactic nuclei (AGNs). Their unique V-shaped spectral feature, characterized by a red optical continuum and a UV excess in the rest frame, challenges us to discern the relative contributions of the galaxy and AGN. We study a spectral energy distribution (SED) model for LRDs from rest-frame UV to infrared bands. We hypothesize that the incident radiation from an AGN, characterized by a typical SED, is embedded in an extended dusty medium with an extinction law similar to those seen in dense regions such as Orion Nebula or certain AGN environments. The UV−optical spectrum is described by dust-attenuated AGN emission, featuring a red optical continuum at λ > 4000 Å and a flat UV spectral shape established through a gray extinction curve at λ < 3000 Å, due to the absence of small-size grains. There is no need for additional stellar emission or AGN scattered light. In the infrared, the SED is shaped by an extended dust and gas distribution (γ < 1; ρ ∝ r
−γ
) with characteristic gas densities of ≃10–103 cm−3, which allows relatively cool dust temperatures to dominate the radiation. As a result, these dust structures shift the emission energy peak from near-infrared to mid-infrared bands in the rest frame; for sources at z ~ 4–7, the corresponding wavelengths shift from the JWST/MIRI to Herschel range. This model, unlike the typical AGN hot torus models, can produce an infrared SED flattening that is consistent with LRD observations through JWST MIRI. Such a density structure can arise from the coexistence of inflows and outflows during the early assembly of galactic nuclei. This might be the reason why LRDs emerge preferentially in the high-redshift Universe younger than 1 billion years.

We provide the total fluxes of our sample using aperture photometry for point-source objects and a 2D Gaussian fitting for objects with extended host galaxy emission, which was used to estimate the unresolved nuclear component. Most galaxies in our sample are pointlike sources; however, four sources (Centaurus A, Circinus, NGC 1068, and NGC 4388) show extended emission in all wavelengths. The 30–40 μm extended emission in NGC 4388 is coincident with the narrow-line region at PA ~ 50°, while the dusty extension at longer wavelengths arises from the host galaxy at PA ~ 90°. Our new observations allow us to construct the best-sampled parsec-scales (spectral energy distributions, SEDs) available between 30 and 500 μm for a sample of nearby AGN. We estimate that the average peak wavelength of the nuclear SEDs is ~40 μm in νF

M giants, with their distinctive properties such as high luminosity, serve as excellent indicators for mapping the structure of the Milky Way. The distance to distant M giants can be determined by using the color–magnitude relation (CMR), which is derived from color–magnitude diagrams of specific systems in previous studies. In this work, we aimed to achieve more accurate distance determination for M giants by focusing on open clusters (OCs) with a large number of member stars and thus improve the CMR. For the first time, we compiled a census of OCs harboring M giants using Gaia Data Release 3 (DR3) and Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data Release 9. We identified 58 M giants associated with 43 OCs and obtained their astrometric and photometric parameters from Gaia DR3. Using the distances of these OCs, we derived the CMR for M giants as a linear correlation, expressed as

. This linear relation proved superior to the empirical distance relation in characterizing the CMR of M giants. The photometric distances of M giants derived from the CMR are consistent with the parallax distances from Gaia and known spectroscopic distances, with median deviations of 1.5% and 2.3%, respectively. Using the distances of M giants derived from the CMR, we computed their radial velocity (V

), azimuthal velocity (V

), and vertical velocity (V

Published: February 2025

In land-scarce Singapore where fresh water is a critical resource, Trichoptera communities can serve as a biomonitoring tool yet are poorly known. This study seeks to address this gap by establishing a preliminary understanding of trichopteran diversity and distribution in Singapore’s freshwater streams. From October 2023–January 2024, 11 stream sites across forested nature reserves (n = 5), buffer parks (n = 4), and urban areas (n = 2) were surveyed for trichopteran larvae. Only eight sites (four in forest streams, four in buffer streams) yielded Trichoptera, totalling 107 larval specimens comprising six families (Calamoceratidae, Ecnomidae, Hydropsychidae, Leptoceridae, Odontoceridae, and Polycentropodidae). Leptoceridae were most abundant, while Ecnomidae was the rarest, and Hydropsychidae were the most widely distributed. In this study, Trichoptera were absent from the urban streams, which had greater depth and total dissolved solids, but similar Trichoptera assemblages and environmental parameters were recorded in both forest and buffer streams. Although differences between the latter two stream types were not statistically significant, buffer streams had the highest abundance and taxonomic richness. Comparison with past literature also reveals differences in recorded Trichoptera diversity, thus this study presents an updated record for Trichoptera in Singapore’s streams. These findings further add to a baseline for future biomonitoring, research, and informing long-term freshwater conservation efforts in Singapore.
Woody flora of the Prof. Dr. Karl Arens Reserve, Corumbataí, São Paulo, Brazil
Authors: Santos Lilian , de Moraes Pedro Luís
Published: February 2025

This study was conducted in the Prof. Dr. Karl Arens Reserve, Corumbataí, São Paulo. The area is a Cerrado fragment, with no records of fire since 1962 and is characterised by the predominance of Cerradão phytophysiognomy. Although several studies have been conducted in the Reserve, there was no testimony material for some species in the Herbarium Rioclarense (HRCB), nor a list of vouchers for any taxon in the main publications. Thus, the objective of this work was to undertake a floristic survey of the woody species in the Reserve, based on herbarium specimens and fieldwork.

The survey in HRCB recorded 510 exsiccatae belonging to 160 species and 44 families. We also conducted 24 fieldwork expeditions between 2019 and 2021 and recorded 118 species in 39 families. In total, 193 woody species were recorded for the Reserve in Corumbataí. Species such as Copaifera langsdorffii and Myrcia neoclusiifolia had already been cited for the area, but there was no testimony material in the herbarium. Machaerium nyctitans and Alchornea glandulosa are examples of new records for the Reserve. Fabaceae, Asteraceae, Myrtaceae, Melastomataceae and Rubiaceae were the families with the greatest species diversity.
Competitive interactions for food resources between invasive Ponto-Caspian gobies and their native competitors in the context of global warming
Authors: Kłosiński Piotr , Kobak Jarosław , Kakareko Tomasz
Published: February 2025

Climate warming can modify the process of biological invasions by affecting the outcomes of competition between alien species and their native counterparts in invaded environments. Inland freshwaters are particularly vulnerable to the intensification of such phenomena due to the accumulation of invaders, including thermophilic species that may benefit from warming. We intended to check whether an elevated summer temperature (25 vs. 17 °C) affects the abilities of the Ponto-Caspian gobies to compete for food. These fish are considered temperature-tolerant, highly invasive freshwater fish in Europe. In laboratory experiments, we tested single- and two-species pairs of juvenile specimens of two goby species and their native counterparts from the same ecological guild (the racer goby Babka gymnotrachelus versus European bullhead Cottus gobio, and monkey goby Neogobius fluviatilis versus native gudgeon Gobio gobio). The fish competed for food (live chironomidae larvae provided at rates below satiation) for 1 hour at night. We analysed behaviours associated with direct interactions (aggression acts) and foraging activity (time to enter the feeder and the time spent in the feeder). We found that although the gobies did not show higher aggression than the natives, they more actively accessed food compared to the latter, irrespective of temperature. Our results suggest that, in the wild, the invasive fish have a competitive advantage over the native ones due to better resource allocation (gaining food without incurring the costs of aggression) and will maintain this advantage as water warming continues.
La Grande Guerra de Monicelli, rupture de la représentation de la Première Guerre mondiale dans le cinéma italien
Authors: Pillosio Raphaël
Published: February 2025

Les représentations cinématographiques de la Première Guerre mondiale par le cinéma italien ont connu une évolution constante marquée par la vie politique du pays. D’une quasi-absence des écrans sous un régime fasciste qui exalte pourtant les anciens combattants et leurs valeurs patriotiques, la Première Guerre mondiale revient en force dans le cinéma populaire italien dans les années 1945-1950 pour ﬁgurer l’unité d’un pays qui s’est déchiré durant la Seconde Guerre mondiale. Il faudra attendre La Grande Guerra de Mario Monicelli en 1959 pour en proposer une comédie distanciée, quand Francesco Rosi dix ans plus tard en livrera une version imprégnée de marxisme : la Première Guerre mondiale est une guerre de classes.
La place des femmes dans l’enseignement technique agricole en France, XIX e –XX e siècle

Published: February 2025

Au sein de l’enseignement professionnel de l’agriculture, placé sous la tutelle du ministère de l’Agriculture, qui se met progressivement en place à compter de 1848, les femmes sont absentes jusqu’en 1886, date de la fondation de la première école professionnelle agricole spécialement destinée aux ﬁlles : l’École pratique de laiterie de Coëtlogon. Ce n’est que dans les premières années du xx e siècle, qu’on voit se développer deux types d’enseignement : l’enseignement postscolaire agricole et l’enseignement saisonnier, où les ﬁlles trouvent leur place avec l’enseignement agricole ménager, et l’enseignement postscolaire ménager. Pour la première fois, la loi du 2 août 1918 donne, à côté de celle des écoles destinées aux jeunes gens, la liste des établissements « dispensant un enseignement professionnel ou technique de l’agriculture » destiné aux jeunes ﬁlles et organisé en trois niveaux. La loi du 2 août 1960 prévoit une élévation générale des niveaux de formation, mais l’enseignement féminin reste toujours sanctionné par des diplômes spéciﬁques. Avec les lois Rocard (1984), de nouvelles missions sont assignées à l’enseignement agricole, mais ce n’est que très progressivement que les différences s’estompent entre les formations ouvertes aux jeunes gens et celles ouvertes aux jeunes ﬁlles. Le pourcentage des jeunes ﬁlles augmente dans l’enseignement supérieur, mais leur devenir professionnel n’est pas toujours au sein de l’exploitation proprement dite.
L’enseignement technique rural au féminin L’exemple de quelques écoles ménagères agricoles privées du Doubs (années 1900-1960)
Authors: Divoux-Bonvalot Adeline , Knittel Fabien
Published: February 2025

Les études historiques concernant les établissements d’enseignement privés confessionnels féminins sont peu nombreuses même si quelques travaux récents commencent à combler cette lacune historiographique. Ce constat est encore plus vrai lorsqu’on prend en compte les écoles ménagères agricoles confessionnelles. Or, l’enseignement féminin privé correspond à un observatoire intéressant pour une étude renouvelée des enseignements techniques et professionnels. Cependant, toute approche globale est encore prématurée, aussi avons-nous choisi de développer une étude de cas consacrée aux écoles ménagères agricoles privées du département du Doubs, depuis les premières créations au début des années 1900 jusqu’aux transformations des années 1960. Notre étude montre les conditions dans lesquelles les écoles d’enseignement technique féminines privées ont été créées et comment elles ont eu des difficultés pour s’inscrire dans la durée. Elle enrichit aussi notre connaissance de l’offre scolaire pour les ﬁlles en milieu rural en même temps qu’elle renseigne plus largement sur la place des femmes dans les campagnes.
Les étudiantes-ingénieurs de l’UTBM (1985 – 2016) : entre épiclérat, transmission maternelle et modernité
Authors: Heyberger Laurent
Published: February 2025

Cet article décrit et analyse la féminisation de la population étudiante de l’Université de Technologie de Belfort-Montbéliard (N = 15 189), de sa création (1985) à 2016, en la situant dans le paysage français des écoles d’ingénieurs et dans le débat académique sur les causes de la sur-sélection des ﬁlles (modèle paternel, modèle maternel, autre modèle explicatif). Numériquement, l’épiclérat est le plus influent, mais le modèle maternel semble davantage déterminer le choix des ﬁlles en dépit de faibles effectifs, dans une population étudiante qui – caractéristique moderne – se distingue de celles des autres écoles par une relative indifférenciation ﬁlles/garçons des modèles parentaux.

Il s’appuie sur un corpus de 79 parcours professionnels de lobbyistes consultants polonais et tchèques ayant une expérience préalable dans le secteur public. Ces parcours attirent l’attention sur deux contraintes structurelles en particulier pour les trajectoires des lobbyistes – le rôle clé joué par les pratiques de patronage partisan par rapport à l’appareil étatique et aux entreprises publiques, et le niveau élevé d’internationalisation des économies nationales, qui fait des entreprises multinationales les clients dominants sur le marché du lobbying. En outre, le pourcentage élevé d’individus qui restent dans le lobbying au cours de la période observée (2000-2023) suggère que ce dernier représente un moyen de rester « près de la politique », dont il est relativement difficile de s’échapper, étant donné les facteurs structurels qui rendent les retours vers la sphère publique à la fois difficiles et peu attrayants.
Quand les revolving doors freinent la réforme européenne sur la transparence des transactions financières
Authors: Vassalos Yiorgos
Published: February 2025

Cet article tente d’évaluer le poids des revolving doors dans l’évolution des politiques publiques. Il étudie le cas de la réforme européenne du régime de transparence des transactions financières suite à la crise de 2008. Il retrace la procédure législative spécifique de cette réforme, à partir des notes des réunions entre agents publics et représentants d’intérêts. Il s’appuie également sur une base de données biographiques des agents impliqués et sur des entretiens avec certains d’entre eux. Ainsi, il met au jour l’existence de liens entre les trajectoires de carrières des agents publics impliqués et le résultat de leurs travaux législatifs.
De l’hémicycle européen à la représentation d’intérêts : des circulations public-privé circonscrites mais des coopérations à bas bruit
Authors: Michon Sébastien , Beauvallet Willy , Robert Cécile
Published: February 2025

Les revolving doors , entendues ici comme la reconversion d’anciens eurodéputés dans des métiers liés au lobbying, ont fait l’objet d’une attention médiatique et politique croissante ces vingt dernières années sans qu’il soit encore facile d’en objectiver le poids, les formes concrètes et les facteurs. Dans cette perspective, l’article exploite une double enquête : des données statistiques sur les devenirs post-mandat (dont le lobbying) d’une population d’élus – la délégation française au Parlement européen – croisées avec des entretiens conduits auprès d’anciens députés et de recruteurs potentiels dans les cabinets et grandes entreprises. On observe d’abord que l’occupation de postes de lobbyistes à temps plein après le mandat est un phénomène statistiquement marginal. L’enquête qualitative permet ensuite d’identifier une série d’explications renvoyant aux frontières professionnelles, y compris dans un espace européen réputé plus flou et plus plastique, entre institution politique et organisations privées/commerciales. L’article montre enfin que, pour autant, de telles trajectoires existent, auxquelles s’ajoutent, surtout, des formes diverses de collaborations avec les structures de représentation d’intérêt dont on s’attache à identifier quels députés y sont plus disposés, et quelles compétences ils y engagent.
Satisfaction des patients hospitalisés lors du premier confinement :
Authors: Cazeneuve Hervé , Capgras Jean-Baptiste , Pascal Christophe , Michel Philippe
Published: February 2025

Dans le cadre du projet COPING (Covid pandemic institutional management), cet article se propose d’étudier les éventuelles variations des perceptions des patients hospitalisés pendant l’épidémie de Covid-19. Pour ce faire, une comparaison entre les périodes confinées et non confinées a été menée à partir des résultats de l’enquête e-Satis disponibles dans les quatre centres hospitaliers universitaires (CHU) de la région Auvergne-Rhône-Alpes (Hospices civils de Lyon, CHU Grenoble-Alpes, CHU de Saint-Étienne, CHU de Clermont-Ferrand). Ce travail permet de constater qu’il existe peu de différences importantes entre les périodes, certaines statistiquement significatives en raison de la puissance de l’étude. Les patients de ces CHU ont vécu pendant l’ensemble de la période une expérience assez similaire à celle des années « non-Covid-19 ». Néanmoins, la période « Covid-19 » est marquée par une contradiction. D’un côté, on observe un renforcement global de la vision positive de l’hôpital et des soignants, ce qui se reflète dans les appréciations portées sur les éléments matériels (des repas et des chambres plus confortables) et immatériels (soins, accueil). De l’autre côté, la baisse de satisfaction concernant les visites et les variations observées tout au long de la période interrogent sur la manière dont des catégories de patients ont appréhendé ces transformations.
Qualité et sécurité des soins : une approche alternative
Authors: Laurent Marius
Published: February 2025

La revue Risques & Qualité publiera progressivement sur son site, à compter de juillet 2022, une série de réflexions et de propositions de l’auteur, dont ce texte constitue l’introduction. Qu’il soit médecin, soignant, ingénieur ou administratif, gestionnaire des risques ou simplement curieux, le lecteur pourra ainsi approfondir ou découvrir les fondamentaux de la sécurité, des théories qui la sous-tendent aux méthodes les plus couramment appliquées, et réfléchir aux progrès possibles face à un univers hospitalier de plus en plus complexe, au sein d’une société qui tolère de moins en moins les mauvaises surprises.
Diminution significative de chutes en établissements pour personnes âgées : retour d’expérience en Belgique
Authors: Istas Laure , Barbier Sophie , Willain Johanne , Pieret Véronique , Schoonvaere Quentin
Published: February 2025

Se basant sur le modèle de l’amélioration et ses trois questions (Que tentons-nous d’accomplir ? Comment saurons-nous si un changement est bien une amélioration ? Quel[s] changement[s] pouvons-nous opérer pour obtenir une amélioration ?), la Plateforme pour l’amélioration continue de la qualité des soins et de la sécurité des patients (Paqs) a accompagné, entre décembre 2020 et mai 2022, les équipes de deux établissements pour personnes âgées belges dans l’application de ce modèle et l’utilisation du run chart. La Séniorie de Longtain et la Résidence Bois du Manil ont ainsi pu suivre dans le temps le nombre de chutes mensuel, mettre en place des actions d’amélioration et observer une diminution statistiquement significative de respectivement 31% et 60%.
Anesthésie et environnement : récupération et recyclage des vapeurs halogénées
Authors: François-Talpaert Camille , Si Serir Djedjiga , Véron François , Sfez Michel , Muret Jane
Published: February 2025

Les gaz anesthésiques, en particulier le desflurane et le sévoflurane, sont des gaz à effet de serre à fort impact sur la pollution atmosphérique. Des dispositifs de récupération et de retraitement commencent à apparaître sur le marché, permettant leur réutilisation dans certains pays (Autriche, Allemagne, mais pas en France). En France, seul le système Contrafluran TM de Baxter/Zeosys Medical est disponible. Ce système permet le recyclage des deux gaz anesthésiques et des composants de la cartouche à des coûts de fonctionnement inférieurs au mode actuel de simple élimination. L’installation de ce système nécessite une contractualisation entre le fournisseur, le fabricant des respirateurs et l’établissement de santé, avec l’appui technique du service biomédical de ce dernier. Son utilisation nécessite une adaptation des pratiques, notamment quant à l’utilisation d’isoflurane et de protoxyde d’azote. Il reste à préciser le rendement effectif du système, tant en termes de récupération des gaz anesthésiques que de réduction de l’effet de serre et d’économie. Un effort industriel et réglementaire à l’échelle européenne est nécessaire, notamment pour pouvoir réutiliser les gaz récupérés et traités à cette fin.
Factor Structure of the Brief Pain Inventory-Short Form in African American Older Adults With Osteoarthritis
Authors: Wu Jianli , Horgas Ann L. , Booker Staja Q.
Published: February 2025

Purpose

To evaluate the factor structure of the Brief Pain Inventory-Short Form (BPI-SF) and measurement invariance across two age groups for African American (AA) older adults with osteoarthritis (OA).

Method

Participants were AA older adults aged 50 to 94 years with self-reported OA and chronic pain (
N
= 110). Cross-sectional data from the BPI-SF were obtained from all participants, and confirmatory factor analysis (CFA) was used to evaluate the factor structure. Measurement invariance across young-old (aged 50 to 69 years) and old-old (aged 70 to 94 years) participants was examined at configural, full metric, and full scalar levels.

Results

CFA revealed that a three-factor model (i.e., pain intensity, activity interference, and affective interference) demonstrated the best fit (χ
2
/df = 1.595, comparative fit index [CFI] = 0.949, root-mean-square error of approximation = 0.074). The change of CFI between configural and metric invariance was below the cutoff point of 0.01, supporting full metric (i.e., factor loadings) invariance across the two age groups. However, full scalar (i.e., item intercepts) invariance was not demonstrated.

Conclusion

Results support a three-factor structure of the BPI-SF, which is consistent across two age groups for AA older adults with OA. This study provides evidence that the BPI-SF can reliably measure pain intensity and two distinct dimensions of pain interference in this population. [

Dispositif de formation à visée émancipatrice et transformative
Authors: Rinaldi Anne-Marie , Wozniak Floriane , Yvain-Prébiski Sonia
Published: February 2025

Cette contribution présente la dimension formative d’une recherche participative née d’une demande d’accompagnement d’un collectif d’enseignants. Après avoir énoncé des principes qui, selon nous, permettent d’envisager une transformation praxéologique et heuristique des pratiques professionnelles, nous exposons notre méthodologie. Nos résultats témoignent de l’intérêt des analyses collectives et de la production d’une ressource structurante et organisatrice par les participants pour assurer la réussite d’une formation émancipatrice qui amène dix enseignants à prendre des décisions et définir des compromis collectifs pour co-construire une progression sur le cycle 2 autour de la soustraction.
Former à la communication à travers les interactions entre pairs : la recherche-action comme contribution à l’amélioration du climat scolaire
Authors: Brito Olivier , Laheyne Cédric
Published: February 2025

Cet article présente la mise en œuvre d’une recherche-action au sein d’une école élémentaire située dans un quartier populaire de l’Ouest parisien. Face à l’émergence de phénomènes de violence à l’intérieur et à l’extérieur de l’école, les membres de la communauté éducative ont identifié des problèmes relationnels ayant pour effet une dégradation du climat scolaire. Dans cette optique, l’article expose les résultats de la recherche-action visant à développer une formation à la communication, au profit des relations école-famille. Il décrit comment les interactions développées au sein d’activités collectives peuvent influencer les dynamiques interpersonnelles et ainsi contribuer à l’amélioration du climat scolaire.
Enjeux épistémologiques et éthiques d’une recherche-action participative dans le développement professionnel d’enseignants d’anglais en CAP
Authors: Tortochot Éric , Olympio Noémie , Hache Caroline
Published: February 2025

Dans le lycée professionnel, en France, le CAP est un diplôme qui peine à mobiliser de nombreux élèves et même les enseignants, notamment en enseignement général. Une recherche-action participative qui vise à la conception collaborative d’une évaluation diagnostique, avec des enseignants d’anglais en formation, peut-elle aider à les remobiliser et à quel prix ? L’enjeu épistémologique, et éthique à la fois, est double : la production de savoirs adaptés autour d’un objet frontière peu consensuel qu’est l’évaluation ; les effets de ces savoirs sur les communautés de pratique impliquées dans le projet.
Une recherche-action participative à l’épreuve des communautés de pratiques en éducation

Published: February 2025

Cet article traite des interactions dans la construction de savoirs au sein d’une recherche-action participative visant l’appropriation d’une technologie numérique en éducation. Cette co-construction est étudiée à travers l’action professionnelle individuelle et collective comme mode légitime de connaissance et de professionnalité. Les savoirs produits sont mixtes car issus de formations « sur le tas » à la frontière entre la communauté enseignante et celle des chercheurs, en amont de formations formelles. Ils reposent sur un partage de connaissances technologiques, pédagogiques et didactiques issues de la pratique interdisciplinaire dans et entre les deux communautés.
