Echo Worlds and Mole-Thinking: Imagining the Nocturnal Sensorium in Nineteenth- and Twentieth-Century Scientific Investigations
Authors: FLACK ANDREW , WOULD ALICE
Published: December 2024

In this article we track the relationship between transforming ways of engaging with animal Otherness in the context of Western scientific writing from the mid-eighteenth through to the early twenty-first century. Specifically, we engage with studies of dark-adapted sensoria. There are few species which seem to have presented such a challenge to the Western, post-enlightenment capacity to imagine Otherness, than those which dwell in darkness. Indeed, naturalists became increasingly confident across the course of the period that variable combinations of technologies and experiments enabled some degree of access to the sensory depths of the animal body. Animals’ fleshy forms, and sensory systems, were conceptualised as bodies of potential knowledge. However, these investigations into animal sensing were highly contextual and reveal as much about the human animal – and its imagined place in the wider world – as they do the animals under study.
Effect of rolling texture on bearing capacity of aircraft repair patches and replaced panels
Authors: Karuskevych Mykhailo , Ignatovych Sergiy , Maslak Tetiana , Karuskevych Oleg
Published: December 2024

The article combines issues related to biaxial fatigue loading, corrections for equivalent stress calculations, and the practical application of new knowledge regarding biaxial fatigue in the aviation industry. It considers the possibility and expediency of taking into account the anisotropy of metals’ mechanical characteristics in aircraft repair procedures, such as patching and replacing damaged skin panels. The biaxial loading of the skin is shown to be a significant factor that should be considered in the aircraft skin repair process. It is shown that while well-known Huber-Mises formula works well for isotropic materials, the fuselage skin made of anisotropic alloys requires corrections to the Huber-Mises method. For aircraft parts subjected to biaxial loading, the assessment of equivalent uniaxial stresses can be done by introducing the crystallographic factor into the Huber-Mises formula. This is achieved by transforming the biaxial stress components of fuselage loading due to pressurization and bending into the resolved stresses in the activated crystallographic slip systems of the dominant texture.
Real-time Pulse Search and Positioning Method for Baseband Data Based on Matched Filtering

Published: December 2024

Fast radio bursts (FRBs) are the most intense radio explosions known, yet their origins remain a significant astrophysical mystery. High-time-resolution pulse searching has opened new avenues for studying narrow and faint pulses, promising substantial improvements in pulse detection efficiency and accuracy and potentially leading to significant scientific discoveries. However, the increase in time resolution results in exponential data volume growth, presenting considerable challenges for data processing. The real-time processing of vast amounts of data and the rapid detection of FRB pulse signals have become bottlenecks in high-time-resolution pulse search research. To address these challenges, we propose a real-time pulse search and positioning method for baseband data based on matched filtering. This method performs preliminary pulse searching and positioning within the baseband data, enabling the selection of effective data segments for subsequent dedispersion and analysis, thereby significantly reducing the data-processing burden. Compared to traditional coherent dedispersion methods, our approach exhibits superior performance in both pulse detection efficiency and dispersion tolerance. Utilizing GPU parallel acceleration, the method can process baseband data streams with 1 ns time resolution in real time, facilitating the detection of narrower and fainter pulse signals. Analysis of 1 ns time-resolution baseband data from FRB 121102 not only successfully identifies all known pulses, but also reveals three new pulses, demonstrating the feasibility and effectiveness of our method.
Convective Mixing in Gas Giant Planets with Primordial Composition Gradients
Authors: Knierim Henrik , Helled Ravit
Published: December 2024

Linking atmospheric measurements to the bulk planetary composition and ultimately the planetary origin is a key objective in planetary science. In this work, we identify the cases in which the atmospheric composition represents the bulk composition. We simulate the evolution of giant planets considering a wide range of planetary masses (0.3–2 M
J), initial entropies (

), and primordial heavy-element profiles. We find that convective mixing is most efficient at early times (ages ≲107 yr) and that primordial composition gradients can be eroded. In several cases, however, the atmospheric composition can differ widely from the planetary bulk composition, with the exact outcome depending on the details. We show that the efficiency of convection is primarily controlled by the underlying entropy profile: For low primordial entropies of

, convective mixing can be inhibited and composition gradients can persist over billions of years. The scaling of mixing efficiency with mass is governed by the primordial entropy. For the same primordial entropy, low-mass planets mix more efficiently than high-mass planets. If the primordial internal entropy would increase with mass, however, this trend could reverse. We also present a new analytical model that predicts convective mixing under the existence of composition (and entropy) gradients. Our results emphasize the complexity in the interpretation of atmospheric abundance measurements and show the great need to better understand the planetary formation process as it plays a key role in determining the planetary evolution and final structure.

Published: December 2024

Continuum reverberation mapping (CRM) of active galactic nuclei (AGN) monitors multiwavelength variability signatures to constrain accretion disk structure and supermassive black hole (SMBH) properties. The upcoming Vera Rubin Observatory’s Legacy Survey of Space and Time will survey tens of millions of AGN over the next decade, with thousands of AGN monitored with almost daily cadence in the deep drilling fields. However, existing CRM methodologies often require long computation time and are not designed to handle such large amounts of data. In this paper, we present a fast and flexible inference framework for CRM using simulation-based inference (SBI) with deep learning to estimate SMBH properties from AGN light curves. We use a long short-term memory summary network to reduce the high dimensionality of the light curve data and then use a neural density estimator to estimate the posterior of SMBH parameters. Using simulated light curves, we find SBI can produce more accurate SMBH parameter estimation with 103–105 times speed up in inference efficiency compared to traditional methods. The SBI framework is particularly suitable for wide-field CRM surveys as the light curves will have identical observing patterns, which can be incorporated into the SBI simulation. We explore the performance of our SBI model on light curves with irregular-sampled, realistic observing cadence and alternative variability characteristics to demonstrate the flexibility and limitation of the SBI framework.

Published: December 2024

The microphysics of the intracluster medium (ICM) in galaxy clusters is still poorly understood. Observational evidence suggests that the effective viscosity is suppressed by plasma instabilities that reduce the mean free path of particles. Measuring the effective viscosity of the ICM is crucial to understanding the processes that govern its physics on small scales. The trails of ionized interstellar medium left behind by the so-called jellyfish galaxies can trace the turbulent motions of the surrounding ICM and constrain its local viscosity. We present the results of a systematic analysis of the velocity structure function (VSF) of the Hα line for ten galaxies from the GASP sample. The VSFs show a sublinear power-law scaling below 10 kpc that may result from turbulent cascading and extends to 1 kpc, which is below the supposed ICM dissipation scales of tens of kpc expected in a fluid described by Coulomb collisions. Our result constrains the local ICM viscosity to be 0.3%–25% of the expected Spitzer value. Our findings demonstrate that either the ICM particles have a smaller mean free path than expected in a regime defined by Coulomb collisions or that we are probing effects due to collisionless physics in the ICM turbulence.

Published: December 2024

A quantitative spectroscopic study of blue supergiant stars in the Hubble constant anchor galaxy NGC 4258 is presented. The non-LTE analysis of Keck I telescope LRIS spectra yields a central logarithmic metallicity (in units of the solar value) of [Z] = −0.05 ± 0.05 and a very shallow gradient of −(0.09 ± 0.11) r/r
25 with respect to galactocentric distance in units of the isophotal radius. Good agreement with the mass–metallicity relationship of star-forming galaxies based on stellar absorption line studies is found. A comparison with H ii region oxygen abundances obtained from the analysis of strong emission lines shows reasonable agreement when the M. Pettini & B. E. J. Pagel calibration is used, while the D. Zaritsky et al. calibration yields values that are 0.2–0.3 dex larger. These results allow us to put the metallicity calibration of the Cepheid period–luminosity relation in this anchor galaxy on a purely stellar basis. Interstellar reddening and extinction are determined using Hubble Space Telescope and JWST photometry. Based on extinction-corrected magnitudes, combined with the stellar effective temperatures and gravities we determine, we use the flux-weighted gravity–luminosity relationship to estimate an independent spectroscopic distance. We obtain a distance modulus m − M = 29.38 ± 0.12 mag, in agreement with the geometrical distance derived from the analysis of the water maser orbits in the galaxy’s central circumnuclear disk.
Spectro-temporal Evolution of 4U 1702-429 Using AstroSat-NICER
Authors: Chattopadhyay Suchismito , Misra Ranjeev , Mandal Soma , Garg Akash , Pandey Sanjay K.
Published: December 2024

We present the broadband spectral and timing properties of the atoll source 4U 1702-429 using two observations of AstroSat with the second one having simultaneous NICER data. For both observations, the spectra can be represented by a Comptonizing medium with a blackbody seed photon source that can be identified with the surface of the neutron star. A disk emission along with a distant reflection is also required for both spectra. For the first observation, the coronal temperature (∼7 keV) is smaller than the second (∼13 keV), and the disk is truncated at a larger radius, ∼150 km, compared to the second, ∼25 km, for an assumed distance of 7 kpc. A kHz quasiperiodic oscillation (QPO) at ∼800 Hz is detected in the first and is absent in the second observation. Modeling the energy-dependent rms and time lag of the kHz QPO reveals a corona size of ≤30 km. A similar model can explain the energy dependence of the broadband noise at ∼10 Hz for the second observation. The results suggest that kHz QPOs are associated with a compact corona surrounding the neutron star and may occur when the disk is truncated at large distances. We emphasize the need for more wide-band observations of the source to confirm these results.
Biodiversity monitoring with intelligent sensors: An integrated pipeline for mitigating animal-vehicle collisions

Published: December 2024

Transports of people and goods contribute to the ongoing 6th mass extinction of species. They impact species viability by reducing the availability of suitable habitat, by limiting connectivity between suitable patches, and by increasing direct mortality due to collisions with vehicles. Not only does it represent a threat for some species conservation capabilities, but animal vehicle collisions (AVC) is also a threat for human safety and security in transport and has a massive cost for transport infrastructure (TI) managers and users. Using the opportunities offered by the increasing number of sensors embedded into TI and the development of their digital twins, we developed a framework aiming at managing AVC by mapping the collision risk between trains and ungulates (roe deer and wild boar) thanks to the deployment of a camera trap network. The proposed framework uses population dynamic simulations to identify collision hotspots and assist with the design of sensors deployment. Once sensors are deployed, the data collected, here photos, are processed through deep learning to detect and identify species at the TI vicinity. Then, the processed data are fed to an abundance model able to map species relative abundance around the TI as a proxy of the collision risk. We implement the framework on an actual section of railway in south-western France benefiting from a mitigation and monitoring strategy. The implementation thus highlighted the technical and fundamental requirements to effectively mainstream biodiversity concerns in the TI digital twins. This would contribute to the AVC management in autonomous vehicles thanks to connected TI.

Published: December 2024

Objective

Immune checkpoint inhibitors (ICIs) have revolutionized cancer outcomes but are limited by immune-related adverse events (irAEs), including rheumatic irAEs (Rh-irAEs). Aging is associated with increased inflammation, referred to as "inflammaging." In this study, we explore the effect of age on severity, frequency, and treatment of Rh-irAEs.

Methods

Adults with new Rh-irAEs after ICI exposure are followed prospectively across 10 Canadian sites as part of the Canadian Research Group of Rheumatology in Immuno-Oncology (CanRIO) prospective cohort. In this study of patients seen between January 2020 and March 2023, we compare the severity of Rh-irAEs and number of irAEs between patients aged ≥ 65 years and < 65 years and explore potential epidemiologic, treatment-related, and phenotypic differences between the older and younger patients.

Results

A total of 139 patients with de novo Rh-irAEs were included, 58 in the younger (aged < 65 yrs) and 81 in the older (aged ≥ 65 yrs) group. There were no significant differences in severity of Rh-irAEs (P= 0.84) or number of irAEs (P= 0.21), although there was a nonsignificant trend toward more younger patients than older patients with ≥ 3 irAEs (24% vs 14%). Types of treatment for Rh-irAEs were similar between the groups. ICI continuation did not differ. Within the ICI-related inflammatory arthritis subgroup, there was also no significant difference in the incidence of severe Rh-irAEs (P= 0.51).

Conclusion

Similar numbers of overall irAEs and severity of Rh-irAEs were observed between older vs younger patients who developed Rh-irAEs after treatment with ICI therapy, suggesting that inflammaging does not play a significant role in Rh-irAEs. Larger studies are needed to explore potential differences in patient phenotypes.
Stock volatility as an anomalous diffusion process
Authors: Arévalo Rubén V. , Conejero J. Alberto , Garibo-i-Orts Òscar , Peris Alfred
Published: December 2024

Anomalous diffusion (AD) describes transport phenomena where the mean-square displacement (MSD) of a particle does not scale linearly with time, deviating from classical diffusion. This behavior, often linked to non-equilibrium phenomena, sheds light on the underlying mechanisms in various systems, including biological and financial domains.

Integrating insights from anomalous diffusion into financial analysis could significantly improve our understanding of market behaviors, similar to their impacts on biological systems. In financial markets, accurately estimating asset volatility—whether historical or implied—is vital for investors.

We introduce a novel methodology to estimate the volatility of stocks and similar assets, combining anomalous diffusion principles with machine learning. Our architecture combines convolutional and recurrent neural networks (bidirectional long short-term memory units). Our model computes the diffusion exponent of a financial time series to measure its volatility and it categorizes market movements into five diffusion models: annealed transit time motion (ATTM), continuous time random walk (CTRW), fractional Brownian motion (FBM), Lévy walk (LW), and scaled Brownian motion (SBM).

Our findings suggest that the diffusion exponent derived from anomalous diffusion processes provides insightful and novel perspectives on stock market volatility. By differentiating between subdiffusion, superdiffusion, and normal diffusion, our methodology offers a more nuanced understanding of market dynamics than traditional volatility metrics.
The TikTok Addiction Scale: Development and validation
Authors: Galanis Petros , Katsiroumpa Aglaia , Moisoglou Ioannis , Konstantakopoulou Olympia
Published: December 2024

Background

There is an absence of valid and specific psychometric tools to assess TikTok addiction. Considering that the use of TikTok is increasing rapidly and the fact that TikTok addiction may be a different form of social media addiction, there is an urge for a valid tool to measure TikTok addiction.

Objective

To develop and validate a tool to measure TikTok addiction.

Methods

First, we performed an extensive literature review to create a pool of items to measure TikTok addiction. Then, we employed a panel of experts from different backgrounds to examine the content validity of the initial set of items. We examined face validity by performing cognitive interviews with TikTok users and calculating the item-level face validity index. Our study population included 429 adults who have been TikTok users for at least the last 12 months. We employed exploratory and confirmatory factor analysis to examine the construct validity of the TikTok Addiction Scale (TTAS). We examined the concurrent validity by using the Bergen Social Media Addiction Scale (BSMAS), the Patient Health Questionnaire-4 (PHQ-4), and the Big Five Inventory-10 (BFI-10). We used Cronbach's alpha, McDonald's Omega, Cohen's kappa, and intraclass correlation coefficient to examine reliability.

Results

We found that the TTAS is a six-factor 15-item scale with robust psychometric properties. Factor analysis revealed a six-factor structure, (1) salience, (2) mood modification, (3) tolerance, (4) withdrawal symptoms, (5) conflict, and (6) relapse, which accounted for 80.70% of the total variance. The concurrent validity of the TTAS was excellent since we found significant correlations between TTAS and BSMAS, PHQ-4, and BFI-10. Cronbach's alpha and McDonald's Omega for the TTAS were 0.911 and 0.914, respectively.

Conclusion

The TTAS appears to be a short, easy-to-use, and valid scale to measure TikTok addiction. Considering the limitations of our study, we recommend the translation and validation of the TTAS in other languages and populations to further examine the validity of the scale.
Reciprocal space mapping of ZnMgY face-centred icosahedral quasicrystals
Authors: Karpus Vytautas , Tumėnas Saulius , Juršėnas Remigijus , Birch Jens , Eriksson Fredrik
Published: December 2024

The reciprocal lattice of face-centred icosahedral ZnMgY quasicrystals was investigated using X-ray diffractometry. A large-scale planar cut of the reciprocal ZnMgY lattice was recorded making use of a PIXcel area detector. The θ-2θ scans along the C5, C3 and C2 symmetry axes revealed numerous diffraction peaks with a large dynamical range of about 106. Low structure-factor diffraction peaks, corresponding to large complementary reciprocal lattice vectors g┴ up to g┴a = 24 (where a is the quasilattice constant), were observed, indicating a high structural quality of ZnMgY quasicrystals. A static linear phason strain was detected in one of the five investigated ZnMgY samples.

Autoformation et numérique : pratiques des enseignants pendant et après la crise du covid-19 en France
Authors: Martineaud Théo
Published: December 2024

Cet article présente une analyse des pratiques d’autoformation des enseignants de l’école élémentaire confrontés au confinement. La fermeture des écoles en France a astreint élèves et enseignants à s’engager dans une « éducation à distance d’urgence » (Bozkurt et al. 2020). Les recherches menées pendant cette période ont analysé les formes d’ingénieries pédagogiques des enseignants (Peraya et Peltier, 2020), la problématique des activités scolaires à domicile (Solari Landa et al., 2023), ou encore les inégalités d’accès aux équipements numériques (Boudokhane-Lima et al., 2021) et les disparités d’usages numériques dans l’enseignement (Michel et Pierrot, 2022). Toutefois, l’autoformation des enseignants aux et avec les techniques numériques reste peu abordée. Partant de définitions issues des sciences de l’éducation et de la formation, mais avec un regard infocommunicationnel, nous analysons les formes qu’ont pu prendre les pratiques d’autoformation des enseignants aux et avec ces techniques via deux séries d’entretiens semi-dirigés réalisés avec des professeurs des écoles et des directeurs en 2021 (n =72) et 2022 (n =46). Cette analyse met en lumière les pratiques d’autoformation hétérogènes des enseignants avec les techniques numériques, de la « débrouille » habituelle à l’urgence du confinement, se formant seuls ou avec leurs pairs pour répondre à leurs besoins et ceux des élèves.
Ludisme et allusion dans l’étymologie poétique latine
Authors: Margelidon Cécile
Published: December 2024

Le jeu étymologique latin, malgré des études de plus en plus nombreuses, a reçu peu de tentatives de définition qui prennent en compte à la fois la singularité de l’étymologie antique et les modalités ludiques mises en œuvre par les poètes. Si les échos sonores et les paronymies sont à la base de certains rapprochements étymologiques antiques, il est important d’avoir une approche poétique du procédé à partir de la manière dont l’origine des mots permet de faire allusion à d’autres récits et de jouer avec les connaissances du lecteur. En quoi l’origine des mots constitue-t-elle alors l’un des moyens dont disposent les poètes latins pour jouer avec les connaissances littéraires, philologiques et antiquaires de leurs lecteurs ? Comment peut-elle entrer dans un processus de connivence avec le lecteur ? Quels sont les traits caractéristiques du ludisme étymologique dans la poésie latine ?
Finding Relatedness: pathways for detecting textual relatedness in the medieval scholastic corpus
Authors: Witt Jeffrey C.
Published: December 2024

Pour montrer l’importance de préparer d’abord les éditions historiques sous forme de données textuelles, tout en laissant la présentation (que ce soit sous forme imprimée ou sur le Web) comme une tâche secondaire en aval, cet article identifie les résultats bénéfiques pour la recherche qui peuvent être obtenus grâce à l’analyse informatique lorsqu’un tel corpus de données textuelles est à portée de main. En mettant l’accent sur la profonde intertextualité caractéristique du corpus scolastique médiéval, il passe en revue trois méthodes distinctes pour détecter différentes formes de relation textuelle au sein du corpus : les intersections de n-grammes, les “document embeddings” et la convolution. Dans chaque cas, une attention particulière est accordée à la façon dont la disponibilité d'un “knowledge graph” spécifique à un domaine nous aide à la fois à préparer correctement le corpus pour l'analyse et à visualiser les résultats de manière à améliorer la recherche. Ces résultats incluent l’observation des tendances dans les pratiques de citation dans différents genres et sous-genres du corpus, le regroupement automatique des questions par similarité et la détection d’une réutilisation textuelle soutenue et non citée.

La ligne de signal
Authors: Ripoll Simon
Published: December 2024

Ce texte est une enquête expérimentale sur une méthode parapsychologique de canalisation des perceptions extrasensorielles, appelée remote viewing (vison à distance), initialement conçue et employée par les services de renseignement américains dans les années 1970 et 1980. Le texte s’ouvre sur une vignette historique qui déplie quelques archives déclassifiées, suivies d’une description pragmatique des opérations du remote viewing. L’auteur expose ensuite un usage direct de cette pratique, en faisant le récit du tournage de son film The Signal Line (67 min, 2024). Le film comme le texte considèrent le remote viewing autant comme un sujet que comme un outil — de narration, de description, de spéculation.

“Entre la máquina y yo” : el rol de la experiencia profesional en contextos en transformación debido a la automatización y sus contribuciones a la reflexión sobre el futuro del trabajo
Authors: Silva Daniel
Published: December 2024

Esta tesis se desarrolló en un momento en que se intensifica la formulación de modelos de trabajo “del futuro”, decretando la necesidad de hacer una “ruptura”, a través de la tecnología, con los actuales modos de trabajar. La investigación buscó introducir otro punto de vista en el debate : el de la actividad, el de quienes viven las transformaciones en contextos concretos. Mediante la realización de dos estudios, uno en el contexto del diseño de futuros vehículos automatizados y otro en la industria del corcho, la tesis pretendió ilustrar el modo en que la experiencia revela criterios que pueden orientar el (re)diseño de las situaciones de trabajo. El primer estudio demuestra cómo el diseño de vehículos automatizados exige tener en cuenta cuestiones que van más allá de una dimensión tecnológica. A su vez, el segundo estudio muestra cómo los modos de producción automatizados “viven” del patrimonio transpersonal de cada entorno profesional, pero no sin coste para la preservación de sí mismo y para la sostenibilidad de los saberes. Estos resultados incitan a reflexionar sobre la renovación de los desafíos éticos, epistemológicos y políticos en la actuación de los psicólogos del trabajo.
« Conquérir la galère. » Espace public et discipline de l’intime chez des femmes sans papiers en Île-de-France
Authors: Le Bars Joanne
Published: December 2024

La violence du dispositif disciplinaire engendrée par la non-détention d’un titre de séjour participe d’une révolution subjective pour les femmes sans papiers et met en tension la sécurité affective et la souveraineté décisionnelle. Elle les contraint à de nouvelles pratiques et conduites dans l’espace public. Le politique vient ici profondément bouleverser le for intérieur et peut avoir des incidences biographiques extrêmes. Par et dans l’espace public se dessinent les traits d’une discipline de l’intimité ou un ordre affectif. Le gouvernement par la peur, la « mise à la rue » et la « mise en mobilité forcée » font partie de ces dispositifs spatiaux qui conduisent à la destruction des liens affectifs et matérialisent la séparation et l’exclusion. L’illégalisation façonne et refaçonne les hiérarchies raciales mais aussi de genre et de classe. La confrontation à une position objective et subjective dévaluée leur enjoint de tenir une féminité respectable dans l’espace public. Elle conduit à une lutte quotidienne où les inégalités sociales, économiques, émotionnelles ainsi que les dispositions genrées et la socialisation raciale se lisent dans les corps et leurs stratégies pour faire face. Mais les tactiques collectives mises en œuvre par ces migrantes dans l’espace public illustrent aussi combien les formes spatialisées des rapports de domination peuvent parfois laisser des interstices de subjectivation et dès lors constituer des exemples d’échecs de ces dispositifs disciplinaires.
Genre, espace et dynamique de la révolution tunisienne : le cas des mobilisations de rue du centre-ville de la capitale
Authors: Kréfa Abir
Published: December 2024

En prenant pour objet les mobilisations de rue du centre-ville de Tunis au cours des première et seconde situations révolutionnaires, l’article croise les analyses féministes avec des classiques de la science politique et qui ont jusqu’ici peu dialogué. Ce croisement conduit à revisiter des concepts et des outils majeurs de la science politique, comme le risque et le protagonisme. L’article montre que les agencements spatiaux genrés en conjoncture révolutionnaire se situent à la fois dans la continuité et en rupture avec ceux qui sont en conjoncture ordinaire, que les ruptures et leur ampleur dépendent du risque et de sa variation. Tout en demeurant structurées par le genre, les situations révolutionnaires s’accompagnent d’une renégociation des frontières genrées spatiales et symboliques, cependant sous certaines conditions : il importe de prendre en compte la dynamique de la révolution.
Saisir les dynamiques de minorisation sociale dans les espaces publics verts des quartiers populaires urbains en France, depuis le point de vue du jardinier municipal
Authors: Koerner Elsa
Published: December 2024

Enquêter sur les représentations qu’ont les jardiniers municipaux des usages de l’espace public suivant une perspective de genre révèle la complexité de l’imbrication des relations de pouvoir et des hiérarchisations sociales. En mobilisant la théorie de la minorisation sociale proposée par Colette Guillaumin, cet article montre comment les espaces publics des quartiers populaires sont considérés comme un lieu où se lisent et se disent les inégalités de genre. Au croisement de processus d’altérisation culturelle, de hiérarchisation spatiale et institutionnelle et des rapports de propriété comme de production, les prescriptions de genre sont perpétuées au risque d’une féminisation de l’espace qui maintiendrait la stigmatisation des hommes des groupes minorisés socialement. La centralité du registre moral dans le discours des jardinier∙es rend compte des rapports de cohabitation dans les jardins publics entre différentes fractions des classes populaires.
Masters of Places: Music and Territory in Makadade (Atauro, East Timor)
Authors: Rappoport Dana
Published: December 2024

On the island of Atauro, certain musical forms are deeply connected to space, which the Adadi conceive of in six primary directions. Each direction is governed by opun (ʻownersʼ, ʻmastersʼ). Specific melodies, rhythms, vocal calls, and instruments, distinguish neighboring territorial zones. This musical polarisation, evident in both discourse and musical content, highlights the importance of the east-west axis, which structures the Adadi territory. Each direction is associated with distinct values, expressed through sound, particularly via complementary instruments that correspond to the eastern and western mountain ranges. The music is part of a system of spatial oppositions relating to place, revealing a hierarchical representation of space and the dynamics of territorial occupation by rival groups.
Heterogeneidad de diagnósticos y diagnósticos de la heterogeneidad. La infancia débil en el sistema educativo argentino, 1900-1910
Authors: Leandri Ricardo González , Finocchio Silvia
Published: December 2024

El artículo analiza el proceso de construcción de sentidos en torno a las no- ciones de diagnóstico y discapacidad en el marco del sistema educativo argentino en la primera década del siglo XX. Para ello indaga en una publicación periódica, El Monitor de la Educación Común, órgano oficial del Consejo Nacional de Educación. Allí reconstruye el pasaje del despertar de cierta sensibilidad por la infancia a principios de siglo a la febril búsqueda de diagnósticos y clasificaciones de la infancia débil en los últimos años de esa década. Lo caracteriza como un proceso plagado de dudas y vacilaciones orientado a detectar problemas asociados a la heterogeneidad infantil para transformar el funcio- namiento del sistema y lograr cumplir con sus objetivos de abarcar al conjunto social.
Trajetórias triunfais idealizadas: Hermann Blumenau e o mito fundador da Colônia Blumenau no sul do Brasil
Authors: Ferreira Cristina
Published: December 2024

Ao discutir a idealização da Colônia Blumenau na historiografia sobre a imigração no Brasil, questiono a legitimação de uma memória histórica de cunho oficial, sustentada por grandes personagens, com o intuito de desconstruir mitos heroicos na história da imigração no Vale do Itajaí. O artigo analisa as relações entre imigração e escravidão, conectando as concepções de Hermann Blumenau como viajante e agente de colonização germânica. A metodologia de pesquisa dialoga com elementos da micro-história, com a análise das peculiaridades locais para ressaltar as diferenças entre o particular (Vale do Itajaí) e o geral (Brasil) nos estudos sobre as trajetórias e a imigração no Brasil, mediante a recusa aos parâmetros e descrições encarceradas na coerência de ideias e percepções. O destaque recai sobre o estudo das divergências e conflitos do cotidiano da imigração, para evitar o mero reducionismo aos simples esquemas de oposição e ressaltar a inter-relação entre Hermann Blumenau e as determinações sociais múltiplas de composição do real em sua atuação.
Nas Laranjeiras: a viagem de Krishnamurti e Maritain ao Brasil e os conceitos de território e ritornello (1935-1936)
Authors: Peixoto Renato Amado
Published: December 2024

Em 1935 e 1936, duas das maiores figuras do mundo religioso visitaram o Brasil, a Argentina e o Uruguai: o místico hindu Jiddu Krishnamurti, que havia sido apontado pela Sociedade Teosófica como o “Instrutor do Mundo”, mas que abandonara essa organização para divulgar uma mensagem de congraçamento, autoconhecimento e libertação pessoal; e o filósofo Jacques Maritain, o principal advogado no catolicismo do pluralismo religioso, do diálogo com a sociedade, da defesa da liberdade e da democracia. A aproximação entre os dois pensamentos não passou despercebida aos radicais: ambos sofreram ferozes críticas e perseguições por parte dos reacionários e fascistas católicos nos jornais, revistas, e nas ruas das cidades por onde passaram. Ainda hoje o espiritualismo de Krishnamurti e o pensamento maritainiano são apontados como embuste ou heresia por aqueles católicos; porém, as críticas desses grupos, aparentemente hegemônicos no catolicismo, foram combatidas de imediato e as ideias conciliadoras acabaram prevalecendo na década seguinte. Buscando compreender a convergência do pensamento maritainiano com os insumos de Krishnamurti e a aceitação inesperada dessas posições no Brasil, procuramos analisar correspondências, periódicos e outras fontes por meio dos insumos de Gilles Deleuze e Félix Guattari, com ênfase nos conceitos de território e ritornello, que procuramos reaproximar das concepções originais desses intelectuais. Entendemos que as passagens de Krishnamurti e Maritain instituíram a fertilização cruzada entre a teosofia e o catolicismo, acarretando, semeando possibilidade de inserção do catolicismo brasileiro no pluralismo, na democracia e na convivência ampla com outras religiões e as diversas ideologias políticas.
Legados do pós-Abolição: historiografia, invisibilidade e o associativismo negro em Laguna/SC

Published: December 2024

Neste artigo, analisa-se como as populações afrodescendentes foram apagadas da história da cidade de Laguna e do Estado de Santa Catarina, bem como os territórios negros criados em um momento de reconfiguração urbana. Por meio de análise da historiografia catarinense e de jornais, percebeu-se que esses dois processos estão atrelados, sendo partes de projetos políticos de modernização do Estado. Desta forma, primeiro serão apresentados o munícipio de Laguna e suas configurações urbanas na virada do século, depois um debate sobre a historiografia de Santa Catarina e o processo de invisibilização das populações afrodescendentes e, por fim, os territórios negros dessa cidade.
Asociaciones civiles, prácticas asociativas y formación de ciudadanía en el periodo de expansión del Estado chileno (1857-1899)
Authors: Baeza Andres
Published: December 2024

El artículo aborda la compleja interrelación entre el proceso de construcción del Estado chileno y el fortalecimiento de lo que podría llamarse “sociedad civil” a través de la proliferación de asociaciones civiles de diversa índole. El período que abarca va desde 1857, cuando entra en vigencia el Código Civil que comienza a regular la constitución de este tipo de organizaciones, hasta 1899. Son aproximadamente cuatro décadas que nos permiten analizar el auge de la constitución de asociaciones civiles cuyo objetivo era cumplir con diferentes fines. Argumentamos que este proceso está interrelacionado y mutuamente influenciado por la expansión del Estado y ambos se cruzan a través de la configuración de un nuevo concepto de ciudadanía, fomentado por las prácticas internas de estas asociaciones.
De volta ao “para uso futuro”?
Authors: Santhiago Ricardo
Published: December 2024

O presente artigo propõe uma reflexão acerca dos desafios metodológicos apresentados e enfrentados pela pesquisa em história oral a partir da eclosão da pandemia de Covid-19 e da situação de isolamento físico por ela ensejada. Conceitua e focaliza as ações de “documentação urgente” do presente, argumentando que elas constituem não um gesto de descontinuidade em relação às tradições de pesquisa em história oral, nem um retorno à ambição documentarista que marca o próprio surgimento da prática de história oral – mas uma prática que se baseia na combinação de propostas metodológicas e proposições teóricas plurais desenvolvidas a partir do uso do método. O artigo assume, por fim, a construção de comunidades narrativas e a visibilização de experiências de sujeitos e grupos em situações de vulnerabilidade como compromissos públicos que se apresentam como imperativos para pesquisadores no e do presente, para os quais a tecnologia se apresenta como desafiadora aliada.

Published: December 2024

To determine the sealing system of arc-spraying aluminum coating for steel structures in high humidity and harsh environments, electrochemical impedance spectroscopy (EIS) was used to study the corrosion resistance and matrix protection of three arc-sprayed aluminum /organic composite coatings in 3.5% NaCl solution. The results indicated that during the 660-day soaking experiment, the coating capacitance of the epoxy-sealing paint system was consistently lower than that of the phosphating primer system and the nano-sealing primer system. The coating resistance showed a decreasing-increasing-decreasing trend but remained above the level of 105 Ω· cm2, and it was higher than the other two systems. The coating reaction resistance remained above 107 Ω· cm2 throughout the entire experimental period, and in the later stage of the experiment, it was 2-3 orders of magnitude higher than the other two systems. It showed that the epoxy sealer system has better shielding performance and corrosion resistance. The protective process of arc-spraying composite coating on the substrate can be divided into four stages: water penetration of organic sealing coating, contact of aluminum coating with medium, formation of shielding layer by corrosion products of aluminum coating, and penetration of corrosion products of aluminum coating to seal pores of organic sealing coating.

With the development of radar-detecting technology, stealth technology is important for military weapons and equipment. As a typical structural stealth material, wave absorption honeycomb has a wide range of application prospects and research value. The light and high absorption wave absorption honeycomb that uses electromagnetic-modified aramid paper as a raw material has the advantages of light density and good absorption performance, making it suitable for the lightweight requirements of the new equipment. Here, the electromagnetic-modified aramid was the raw material of the honeycomb. The hexagon honeycomb and overexpanded honeycomb were prepared. We also analyzed the influence of the cell shapes on the honeycomb properties. The results showed that cell shapes had little effect on the plane compression and shear performance of L. The overexpanded honeycomb’s L and W shear performance was basically the same. The hexagon and overexpanded honeycomb have good electromagnetic wave absorption performance in 1 GHz ~ 18 GHz frequency band.
The Impact of Surface Treatment Processes on the Fatigue Life of Fasteners

Published: December 2024

Titanium alloy fasteners are extensively used in advanced fields such as aerospace due to their corrosion resistance, high-temperature endurance, low density, and high strength-to-weight ratio. In practical applications, fatigue failure is the primary failure mode for these fasteners. Besides the operational environment, the manufacturing process, especially surface treatment techniques, plays a crucial role in affecting the fatigue life of titanium alloy fasteners. This paper examines the impact of three surface treatment processes-rolled fillet, pulsed anodization, and molybdenum disulfide coating－on the fatigue life of titanium alloy fasteners through orthogonal experiments. The study finds that both rolled fillet and molybdenum disulfide coating significantly influence the fatigue life. This effect is associated with residual stresses, where compressive residual stress initially increases with rolling pressure but subsequently decreases, and reduces as the thickness of the molybdenum disulfide lubricating film rises.
