M dwarfs are ubiquitous in our Galaxy, and the rate at which they host stellar companions, and the properties of these companions, provide a window into the formation and evolution of the star(s), and of any planets that they may host. The Pervasive Overview of “Kompanions” of Every M dwarf in Our Neighborhood (POKEMON) speckle survey of nearby M dwarfs is volume limited from M0V through M9V out to 15 pc, with additional targets at larger distances. In total, 1125 stars were observed, and 455 of these are within the volume-limited, 15 pc sample of M-dwarf primaries. When we combine the speckle observations with known companions from the literature, we find that the stellar multiplicity rate of M dwarfs within 15 pc is 23.5% ± 2.0%, and that the companion rate is 28.8% ± 2.1%. We also find that the projected separation distribution for multiples that are known to host planets peaks at 198 au, while the distribution for multiples that are not yet known to host planets peaks at 5.57 au. This result suggests that the presence of close-in stellar companions inhibits the formation of M-dwarf planetary systems, similar to what has been found for FGK stars.

TOI-677 b is part of an emerging class of “tidally detached” gas giants (a/R
⋆ ≳ 11) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet formation, which must account for the excitation of high eccentricities without large changes in the orbital inclination. In this work, we present a new Rossiter–McLaughlin measurement of the tidally detached warm Jupiter TOI-677 b, obtained using high-precision radial velocity observations with Magellan’s Planet Finder Spectrograph (PFS). Combined with previously published observations from the Very Large Telescope’s ESPRESSO spectrograph, we derive one of the most precisely constrained sky-projected spin–orbit angle measurements to date for an exoplanet. The combined fit offers a refined set of self-consistent parameters, including a low sky-projected stellar obliquity of

, which further constrain the puzzling architecture of this system. We examine several potential scenarios that may have produced the current TOI-677 orbital configuration, ultimately concluding that TOI-677 b most likely had its eccentricity excited through disk–planet interactions. This system adds to a growing population of aligned warm Jupiters on eccentric orbits around hot (T
eff > 6100 K) stars.
Double-decker Pair of Flux Ropes Formed by Two Successive Tether-cutting Eruptions

Published: March 2024

Double-decker filaments and their eruptions have been widely observed in recent years, but their physical formation mechanism is still unclear. Using high spatiotemporal resolution, multi-wavelength observations taken by the New Vacuum Solar Telescope and the Solar Dynamics Observatory, we show the formation of a double-decker pair of flux rope system by two successive tether-cutting eruptions in a bipolar active region. Due to the combined effect of photospheric shearing and convergence motions around the active region’s polarity inversion line (PIL), the arms of two overlapping inverse-S-shaped short filaments reconnected at their intersection, which created a simultaneous upward-moving magnetic flux rope (MFR) and a downward-moving post-flare-loop (PFL) system striding the PIL. Meanwhile, four bright flare ribbons appeared at the footpoints of the newly formed MFR and the PFL. As the MFR rose, two elongated flare ribbons connected by a relatively larger PFL appeared on either side of the PIL. After a few minutes, another MFR formed in the same way at the same location and then erupted in the same direction as the first one. Detailed observational results suggest that the eruption of the first MFR might experienced a short pause before its successful eruption, while the second MFR was a failed eruption. This implies that the two newly formed MFRs might reach a new equilibrium at relatively higher heights for a while, which can be regarded as a transient double-decker flux rope system. The observations can well be explained by the tether-cutting model, and we propose that two successive confined tether-cutting eruptions can naturally produce a double-decker flux rope system, especially when the background coronal magnetic field has a saddle-like distribution of magnetic decay index profile in height.
Kerr-scalaron Metric and Astronomical Consequences near the Galactic Center Black Hole
Authors: Paul Debojit , Bhattacharjee Pranjali , Kalita Sanjeev
Published: March 2024

Astronomical tests of spacetime metric and gravitation theory near the Galactic center (GC) black hole, Sgr A*, have gained momentum with the observations of compact stellar orbits near the black hole and measurement of the black hole shadow. Deviation from the Kerr metric is a potential signature of modified gravity theory. In this work, we use the Newman–Janis algorithm to construct an axially symmetric and asymptotically flat metric in f(R) scalaron gravity theory. We call it the Kerr-scalaron metric. To study the astronomical consequences of the new metric, we use the compact stellar orbits and the black hole shadow. We use the observed size of the emission ring of the GC black hole shadow for estimating the deviation of the new metric from general relativity. It has been found that scalarons with masses within 10−17–10−16 eV are compatible with the observed emission ring size for a black hole spin of χ = 0.9. The Schwarzschild limit of the pericenter shift is estimated for compact stellar orbits near the black hole. General relativistic pericenter shift in wider orbits, including S stars such as S4716 and S2, has been reproduced with these scalarons. The parameter f
SP measuring the deviation from Schwarzschild pericenter shift has been found to be f
SP = 1.00–1.04 within stellar orbits with semimajor axes of 45–100 au. Scalarons have the capability to dominate Schwarzschild precession for orbits with semimajor axes much smaller than 45 au. Lense–Thirring (LT) precession with the new metric is estimated for the compact orbits. The massive scalarons produce LT precession with magnitude (12.25–24.5) μas yr−1 in the orbit of S2. The LT precession timescale is within 0.1% of the age of the S stars.
Optimizing NILC Extractions of the Thermal Sunyaev–Zel’Dovich Effect with Deep Learning
Authors: Pratt Cameron T. , Qu Zhijie , Bregman Joel N. , Miller Christopher J.
Published: March 2024

All-sky maps of the thermal Sunyaev–Zel’dovich effect (SZ) tend to suffer from systematic features arising from the component-separation techniques used to extract the signal. In this work, we investigate one of these methods, known as needlet internal linear combination (NILC), and test its performance on simulated data. We show that NILC estimates are strongly affected by the choice of the spatial localization parameter (Γ), which controls a bias-variance trade-off. Typically, NILC extractions assume a fixed value of Γ over the entire sky, but we show there exists an optimal Γ that depends on the SZ signal strength and local contamination properties. Then we calculate the NILC solutions for multiple values of Γ and feed the results into a neural network to predict the SZ signal. This extraction method, which we call Deep-NILC, is tested against a set of validation data, including recovered radial profiles of resolved systems. Our main result is that Deep-NILC offers significant improvements over choosing fixed values of Γ.

Star formation quenching is one of the key processes that shape the evolution of galaxies. In this study, we investigate the changes in molecular gas and star formation properties as galaxies transit from the star-forming main sequence to the passive regime. Our analysis reveals that as galaxies move away from the main sequence toward the green valley the radial profile of specific star formation rate surface density (ΣsSFR) is suppressed compared with main-sequence galaxies out to a galactocentric radius of 1.5 R
e(∼7 kpc for our sample). By combining radial profiles of gas fraction (f
gas) and star formation efficiency (SFE), we can discern the underlying mechanism that determines ΣsSFR at different galactocentric radii. Analysis of relative contributions of f
gas and SFE to ΣsSFR uncovers a diverse range of quenching modes. Star formation in approximately half of our quenching galaxies is primarily driven by a single mode (i.e., either f
gas or SFE), or a combination of both. A collective analysis of all galaxies reveals that the reduction in star formation within the central regions (R < 0.5 R
e) is primarily attributable to a decrease in SFE. Conversely, in the disk regions (R > 0.5 R
e), both f
gas and SFE contribute to the suppression of star formation. Our findings suggest that multiple quenching mechanisms may be at play in our sample galaxies, and even within a single galaxy. We also compare our observational outcomes with those from galaxy simulations and discuss the implications of our data.
Unveiling ancient diversity of long-tailed wasps (Hymenoptera: Megalyridae): new taxa from Cretaceous Kachin and Taimyr ambers and their phylogenetic affinities

Published: March 2024

The Megalyridae are a small family of parasitoid wasps comprising eight extant genera (71 species) and six extinct genera (13 species). Here, we report eight new species from Late Cretaceous Kachin (Myanmar) and Taimyr (Russia) ambers; the family is recorded for the first time from the latter. †Cretolyra noijebumensisgen. et sp. nov., †Cretolyra shawigen. et sp. nov., †Genkyhag innebulagen. et sp. nov., †Megacoxa chandrahrasagen. et sp. nov., †Megacoxa janzenigen. et sp. nov., and †Megacoxa synchrotrongen. et sp. nov., are described from late Albian – early Cenomanian Kachin amber; †Kamyristi exfrigoregen. et sp. nov. and †Kamyristi yantardakhensisgen. et sp. nov. from Taimyr amber (Baikura, late Albian – early Cenomanian Ognevka Formation and Yantardakh, Santonian Kheta Formation, respectively). Phylogenetic analyses of the family are presented and the classification of the Megalyridae is revised accordingly. A new tribe, †Megalavinitrib. nov., is erected to accommodate †Cretolyragen. nov., †Genkyhaggen. nov., †Megacoxagen. nov. together with †Megalava Perrichot, 2009; †Megalavinitrib. nov. is characterized by the vein M fully pigmented and veins Rs+M and M+Cu aligned, the crenulate mesometapectal sulcus, and the pronotal spiracle not posteriorly surrounded by cuticle. This spiracular condition was previously only observed in †Megazar Perrichot, 2009, thus the subfamily †Megazarinae Perrichot, 2009 stat. nov. is proposed for the clade (†Megalavini + †Megazar), as sister to the remaining Megalyridae. The latter is defined as the Megalyrinae, with †Kamyristigen. nov. being retrieved as sister to all other genera except Rigel Shaw, 1987 under parsimony analyses. To align phylogeny with classification, three new tribes are erected (†Kamyristinitrib. nov., †Megallicinitrib. nov., and †Valaainitrib. nov.) and the †Cretodinapsini is synonymized under Megalyrini. A grouping [Rigel + Megalyridia] is supported under Bayesian analyses, which is the only specific conflict with the parsimony analyses, suggesting some degree of caution with respect to the internal relationships of the Megalyrinae. Finally, a revised key to the Megalyridae genera is provided.
Unravelling the mishmash: A new phylogeny for the family Empheriidae (Psocodea, Trogiomorpha) with a new genus and species from Cretaceous Charentese amber
Authors: Álvarez-Parra Sergio , Nel André , Perrichot Vincent , Jouault Corentin
Published: March 2024

The order Psocodea, including barklice, booklice, and parasitic lice, is diverse and widely distributed since the Cretaceous. That is particularly the case for the speciose extinct family Empheriidae (Psocodea, Trogiomorpha, Atropetae), recently fused with the ‘Archaeatropidae’. Understanding the evolution of barklice is dependent in part on studying this family, as its representatives have been found from the Early Cretaceous to the Eocene, surviving the K/Pg extinction event. The phylogenetic relationships of Empheriidae in relation to other families, such as Lepidopsocidae or Psoquillidae, have been extensively debated. However, distinguishing diagnostic characters for the Empheriidae has proven challenging. In this study, we describe the new empheriid Santonipsocus mimeticusgen. et sp. nov. from Cretaceous Charentese amber (France). It is the third empheriid species found in this locality. The new genus is compared with the other genera in the family, and Proprionoglaris guyoti and Proprionoglaris axioperierga are revised based on the type material and new specimens. We explore the phylogeny of Empheriidae, both the relationships with other families and the inner relationships between the genera, through maximum parsimony analysis and Bayesian inference analysis. Our results suggest that Empheriidae may represent a paraphyletic evolutionary grade to the rest of Atropetae. The phylogenetic relationships between genera align with the biogeography of the family and support previous hypotheses. In addition, we discuss the possible biology of the members of the family, shedding light on the evolutionary history of Empheriidae.
Development of a field diagnostic tool for Schistosoma mansoni Praziquantel resistant markers in selected endemic communities
Authors: Acquah Maame Ekua , Aboagye Frank , Ashong Yvonne , Mosi Lydia
Published: March 2024

Schistosomiasis is a neglected tropical disease that affects more than 200 million people and 45% of infections have been shown to occur in school-aged children. A large percentage of the disease burden lies in Africa. In 2012, the WHO outlined a roadmap for the elimination of schistosomiasis by 2020; however, this was not achieved. Treatment for schistosomiasis is by the use of Praziquantel, a drug in use for over 30 years and there is a concern for emerging drug resistance. There are several species of the genus Schistosoma causing infection in humans. For this study, Schistosoma mansoni which causes intestinal schistosomiasis will be investigated. There are reports of lowering cure rates and suboptimal response to praziquantel following several cycles of mass drug administration (MDA). Praziquantel resistance has also been reported in some countries and laboratory-bred schistosome experiments. To address the concerns of resistance, this study aims to employ a two-part approach to assess the prevalence of S. mansoni. praziquantel resistance amongst school-aged children in schistosomiasis endemic communities in Ghana and develop a diagnostic tool to aid in field assessment of infections. To achieve this, the study will attempt to answer the following research questions: 1. Is there developing S. mansoni praziquantel resistance in communities that have undergone several mass drug administrations? 2. Is there an interplay between intermediate host exposure to praziquantel and the development of praziquantel drug resistance in the definitive host?
Une soirée Zoom avec La Femme de ma vie . Quand le théâtre confiné se joue en ligne et en direct

Alors qu’en 2020, les Français·es se sont vu·es imposer des périodes de confinement durant la crise sanitaire liée à l’épidémie de la Covid-19, de nouvelles modalités de consommation de la culture sont passées, entre autres, par une refonctionnalisation des médias. Des innovations culturelles ont pu naître en ligne, comme la mise en place du site https://www.directautheatre.com/ par l’acteur Robert Plagnol à l’origine de la création de la pièce La Femme de ma vie d’Andrew Payne, qu’il a jouée en direct sur Zoom. Nous étudions la manière dont le dispositif en ligne reconfigure à la fois l’épiphanie d’une pièce de théâtre, mais aussi le périmètre de l’expérience spectatorielle circonscrit par les agencements formels déployés. Nous nous appuyons sur l’analyse de deux représentations en décembre 2020 et mars 2021, éclairée par un entretien avec l’acteur à l’initiative du site, ainsi que des propos issus d’un focus group et de trois entretiens semi-directifs menés avec des spectateur ·rices ayant eux-mêmes et ellesmêmes pris leur billet.
La justice constitutionnelle à l’épreuve du renseignement : le Conseil constitutionnel est-il le gardien du « trésor des droits de l’Homme » ?
Authors: Veron Noémie
Published: March 2024

Depuis l’adoption de la loi du 24 juillet 2015, le Conseil constitutionnel s’est saisi de la question de la protection constitutionnelle des droits fondamentaux lorsqu’ils doivent être conciliés avec le renseignement en forgeant une politique jurisprudentielle singulière. Jusqu’ici, il s’est intéressé à l’ensemble des moyens octroyés aux services ainsi qu’aux contrôles auxquels ils sont assujettis. Il a fait le choix d’un contrôle global en s’assurant de l’existence de garanties minimales à des restrictions maximales des droits et libertés. Les effets anesthésiants du renseignement sont évidents : le Conseil constitutionnel opte pour un contrôle de proportionnalité réduit à son paroxysme. Les censures sont peu nombreuses, et ne concernent que des dispositions législatives n’ayant prévu aucunes contreparties à l’action du renseignement ou des dispositions techniques et résiduelles au regard des pouvoirs conférés aux services.
Reining in Pegasus: The Oversight of the Spanish Intelligence Service in the Catalangate
Authors: Díaz-Fernández Antonio M.
Published: March 2024

The Pegasus spyware case, revealed in July 2021, also impacted Spanish politics when a report produced by Citizen Lab denounced that Catalan independentists had been surveilled using this software. The scandal — known as Catalangate — highlighted the need for a thorough audit of these surveillance capacities in the hands of the Spanish intelligence service. Using Catalangate as a case study, this article analyses whether Spanish mechanisms for controlling the surveillance capacities of the National Intelligence Centre (CNI) have followed the procedures established in Spanish legislation. Our conclusion is that the Spanish control system worked effectively. When the Parliamentary committee was unable to fulfill its duties, another actor within the democratic system, the Ombudsman, filled that gap. Secondly, the article analyses if Spanish control mechanism meets the more recent standards of case law from the European Court of Human Rights (ECHR), and the Court of Justice of the European Union (CJEU). This case law emphasises the importance of procedural guarantees for legitimising both bulk and targeted surveillance procedures, showing the need for potential improvements in Spanish regulations.

Surveiller une aire marine protégée : pratiques, logiques et processus de coercition au Sénégal
Authors: Diallo Mariama
Published: March 2024

L’étude de la surveillance des aires protégées au Sénégal est une entrée pertinente pour appréhender les pratiques coercitives des éco-gardes, leur travail de police et les processus à travers lesquels ils s’imposent en tant qu’acteurs du maintien de l’ordre. Elle ouvre une perspective d’analyse des postures et des pratiques des éco-gardes quand ils sont au travail et en interaction avec les citoyens. La surveillance permet d’observer comment, en présence et en marge de l’État, un système de régulation local se produit et se reproduit au quotidien. En dépit de leur reconnaissance officielle, qui est presque un sujet tabou au Sénégal, les éco-gardes font au quotidien un travail de police maritime qui, pendant longtemps, était une chasse gardée de l’État. Explorer leurs pratiques par le bas permet ainsi de comprendre les processus et les mécanismes à travers lesquels s’opèrent les pratiques coercitives des éco-gardes et leur insertion dans des dynamiques plus larges de gouvernementalité à l’aune des réformes du champ de la conservation et de la décentralisation au Sénégal.
Quelques réflexions à propos de fins d’analyses chez des patients narcissiques
Authors: Haber Maurice
Published: March 2024

L’article est centré sur les particularités des fins d’analyses de trois patients narcissiques. Leur brusque détermination à interrompre l’analyse est attribuée à un double impératif : le refus de renoncer à un idéal associé à l’économie narcissique et la difficulté de montrer et de vivre dans la relation analytique les progrès et les changements dus à l’analyse. Ces analysants évitent les vécus de deuil, son élaboration anticipatrice sans qu’il soit pour autant possible d’affirmer qu’aucun travail de deuil n’ait été accompli. L’analyste a constaté dans son contre-transfert la reconnaissance du souhait d’autonomie de ces patients, leur départ n’étant pas seulement ressenti comme une fuite. Ce vécu a induit une attitude contre transférentielle en relation avec la conviction intime que, par leur démarche, ces analysants traduisaient, parmi d’autres déterminismes, le désir d’être reconnus au plus primitif d’eux-mêmes comme sujets originaux capables d’autonomie.
Ratio d’équité salariale et démocratie actionnariale au Canada

Published: March 2024

Cette étude examine la rhétorique des entreprises canadiennes ciblées par des actionnaires activistes pour convaincre l’ensemble des actionnaires de voter contre les projets de résolution déposés par des actionnaires minoritaires. Ces projets exigent la divulgation du ratio d’équité salariale au sein de leur entreprise. Les analyses réalisées sur une population de 39 résolutions soumises entre les années 2008 et 2020 inclusivement, montrent que les entreprises conseillent à leurs actionnaires lors de l’assemblée générale de voter contre ces projets de résolution en utilisant des stratégies rhétoriques de légitimation. Cette rhétorique semble prise en compte par l’assemblée générale puisque les votes « en faveur » de ces projets de résolution atteignent en moyenne seulement 7 %.

Published: March 2024

Cet article étudie la pertinence de la pyramide de Visser (2006) pour appréhender les pratiques de Responsabilité Sociale de l’Entreprise des Firmes MultiNationales (FMNs) opérant à Madagascar. Les données ont été collectées de 2017 à 2020 à l’aide de huit entretiens semi-directifs de responsables RSE de FMNs ainsi que 38 documents internes et 49 documents externes. Nos données montrent que dans l’environnement malgache, les engagements philanthropiques ainsi que les responsabilités économiques sont considérés comme les composantes prioritaires de la RSE. Les responsabilités éthiques et juridiques y sont des composantes perçues comme secondaires. Nous proposons ainsi une variante du modèle de Visser plus appropriée pour le territoire malgache. Notre étude montre ainsi comment les FMNs peuvent optimiser leur implantation ainsi que leur contribution au développement de Madagascar. Nous discutons enfin les résultats, les contributions, les limites ainsi que les perspectives associées à notre étude.
À la recherche d’un droit à l’éducation à une alimentation saine et durable dans le cadre européen
Authors: Nivard Carole
Published: March 2024

L’action européenne en faveur d’une alimentation plus saine s’est traduite par l’émergence d’un droit à l’information des consommateurs accompagné de son corollaire, le droit à l’éducation alimentaire. L’idée est en effet d’armer le consommateur pour l’orienter vers des choix conscients et éclairés. Cette action est-elle suffisante au regard des nombreux facteurs et enjeux affectant la consommation alimentaire ? L’alimentation présente des dimensions multiples : bien au-delà d’assurer au consommateur des nutriments sains, elle relève d’un débat culturel, citoyen et démocratique sur la justice sociale dans nos sociétés et la durabilité de nos systèmes alimentaires. À cet égard, l’article s’interroge sur l’intérêt qui résulterait d’un changement de paradigme au travers d’une appréhension de l’éducation alimentaire en termes de droit de l’homme. Une telle consécration pourrait engager à une action plus exigeante et effective des organisations européennes et donc, de leurs États membres, quant au respect d’un tel droit.

La théorie du complot est une figure dominante de nos sociétés contemporaines. Toute menace, toute atteinte à l’ordre moral, tout vecteur de la modernisation de la société ont systématiquement été perçus par l’opinion réactionnaire, depuis la Révolution française, comme les effets d’une puissance occulte qu’il s’agissait de diaboliser. La franc-maçonnerie fut particulièrement visée de ce point de vue.

Sous forme de roman policier, José Cardoso Pires écrit une métafiction historiographique dans laquelle il refait l’enquête sur un crime qui a eu lieu dans la région de Lisbonne en 1960. Mais plus que de découvrir s’il s’est agi d’une conspiration politique ou d’un complot au sein d’un groupe d’activistes contre le régime salazariste, il s’agit ici de faire œuvre de mémoire et de réflexion sur des faits passés qui peuvent avoir une incidence sur le présent et le futur des sociétés confrontées à l’hypocrisie des pouvoirs.
A mathematical model with control strategies for marijuana smoking prevention
Authors: Ullah Atta , Sakidin Hamzah , Shah Kamal , Hamed Yaman , Abdeljawad Thabet
Published: March 2024

Our goal of this study is to prevent marijuana smoking in the human population. In this manuscript, an updated mathematical model was established by incorporating two additional compartments: The hospitalized class and the prisoner's class. The updated model was validated, and it was shown to be novel compared to the non-user, experimental, recreational, and addicted (NERA) users' model. This distinction was crucial as it was challenging to prevent marijuana usage without these realistic classes. The entire population was split into six primary groups, including these new classes: non-users, experimental, recreational, addicted, hospitalized, and prisoners' class. Additionally, control techniques for marijuana prevention in the population were addressed with the aid of sensitivity analysis. The important point at which we may have determined the preliminary transmission rate of marijuana smoking was the basic reproductive number $ {\mathbb{R}}_{0} $. Utilizing MATLAB, the Runge-Kutta method of order four was employed for the numerical simulation of the updated model to investigate the impact of control measures on marijuana smoking prevention.
Le chant comme outil d’incitation à l’action collective : le cas du mouvement social guyanais de mars-avril 2017
Authors: Hidair-Krivsky Isabelle
Published: March 2024

Le discours manifestant est étudié à travers l’analyse des énoncés spécifiques que sont les chants entendus lors du mouvement social guyanais de mars-avril 2017. Nous qualifions ce dernier de majeur pour deux raisons : tout d’abord, du point de vue de son ampleur et de sa durée, puisqu’il a bloqué l’ensemble du territoire durant cinq semaines ; et ensuite, par sa visibilité médiatique, puisqu’il a été relayé par la presse nationale et internationale. En retenant le contexte de communication qu’est la manifestation, les dimensions sociale, historique et politique sont privilégiées afin de cerner le fonctionnement du chant revendicatif et de l’envisager comme outil d’incitation à l’action collective. Nous interrogeons trois chansons qui ont servi de support à des revendications sociales sur fond de tensions économiques, politiques et identitaires.
Métiers d’ingénierie pédagogique en charge du numérique face au défi de la digitalisation de formation au sein des organismes privés

Loin d’être anecdotique, l’expressivité singulière de l’album suscite notre intérêt. Il nous semble que c’est aux fondements mêmes de son identité, au cœur de ses compositions artistiques, que se joue l’enjeu d’une rencontre esthétique avec l’oïkos (notre maison). L’expérience de nature de l’enfant s’est aujourd’hui largement appauvrie : nous n’avons peut-être jamais eu autant besoin d’histoires qui puissent agir comme de puissantes écoformations.
Imagining Indigenous Consent and Indigenous Right to Resist in Colonial Latin America
Authors: Herzog Tamar
Published: March 2024

This text examines Portuguese and Spanish documentation to show that Iberians invoked a variety of ways by which the indigenous inhabitants of the Americas could consent to their presence and domination. According to these sources, indigenous consent could be explicit or implicit, and it could be free or coerced, with each one of these situations giving rise to a distinct assessment of indigenous right to resist. By observing developments both in the colonies and in Europe, and by surveying both legal doctrine and practice, this article asks: how did Iberians structure and use consent, and what could it do for them? Why and how did they insist on consent when there was little to no possibility to refuse? This article is part of the special theme section on Consenting to Early Modern Empires, guest-edited by Sonia Tycko.
Pour une démarche de conception orientée milieux
Authors: Simoncini Nicolas , Triclot Mathieu , Noûs Camille
Published: March 2024

Cet article revient sur une démarche de conception orientée par la notion de milieux techniques. Nous présentons les dynamiques temporelles communes à deux projets technologiques dans lesquels nous sommes intervenus, les décrivant à travers l’échec de phases d’abstraction et de concrétisation initiales, en reprenant le vocabulaire simondonien. Les difficultés rencontrées, à la fois dans le développement technique et dans la résistance des utilisateurs présumés, conduisent à une bascule du regard : d’une conception centrée sur le dispositif à une autre centrée sur la relation transformatrice entre le dispositif et son milieu. Nous mettons en avant trois aspects de cette transformation : un changement d’échelle, passant d’un regard centré sur le dispositif à l’exigence de « repeupler les milieux », en découvrant de nouveaux acteurs susceptibles d’entrer en relation avec la technique ; un changement d’ontologie, mettant l’accent sur la manière dont les relations transforment leurs termes et dont les techniques reconfigurent les activités ; et, enfin, l’adoption d’une posture normative, à la croisée entre les normes éthiques dont se réclament les projets, l’éthique concrète des acteurs de terrain et l’exigence de concevoir de « bons milieux ».

Confraternities and Confreres Promoting Gastronomic Identity and Local Products
Authors: Fernandes Gonçalo Poeta , Costa Adriano Azevedo , Cerveira Rui
Published: March 2024

Considering gastronomy as a source of expression of local culture, its use in tourism can contribute to enhancing and adding value to the destination, as well as encourage the pride of the local community, stimulating its production and consumption, and its dissemination outside the region. Bucho Raiano is a gastronomic product of identity and representativeness for the inland border region of Portugal (Riba Côa), for which its confraternity seeks the dissemination, the promotion of its consumption, and enhancement as a cultural resource. Gastronomic cofraternities play an important role in disseminating, promoting, and defending the agri-food products and quality gastronomy of a particular region, maintaining the historical legacy of the customs and respective peoples or regions, and contributing to the cultural and tourism valorisation of the territories to increase the tourists. Thus, this research aims to contextualize the Confraria do Bucho Raiano as a case study, its strategies and contributions to the promotion and enhancement of this gastronomic product.

Published: March 2024

The São Francisco Valley, in the northeastern semi-arid region of Brazil, has attracted national and international wineries due to investments in research and technology, resulting in unusual growth in cities in the northeastern backlands. With 300 days of sunshine per year, it has developed irrigated agriculture, with grapes as the main product, allowing for up to two and a half harvests per year. The government and entrepreneurs are preparing for tourism, focusing on wine production. A study is analyzing the actions of social actors in wine tourism, using a qualitative and bibliographic approach, as well as visits to municipalities and wineries. Wine tourism is seen as a strategy to develop destinations and integrate micro-regions, promoting combined attractions and integration between rural areas and society in general. The results will provide theoretical and practical considerations for viticulture and tourism.

Sustainable Food Waste Utilization in the Context of the Indian Hospitality Industry
Authors: Singh Sujay Vikram , Singh Kuldeep , Kumar Nishant
Published: March 2024

This abstract investigates how contemporary sustainability programs affect sustainable food consumption, food waste management, waste reduction, circular supply networks, and ecologically beneficial behaviors. Given growing environmental concerns, traditional food production and consumption must be entirely rethought. Sustainable food consumption emphasizes circular supply chain models and eco-friendly approaches to reduce waste. These activities aim to reduce food's life cycle's environmental impact. From source to consumption, waste reduction is essential. These solutions promote circularity and resource responsibility. Adopting a closed-loop supply chain ensures food waste is reused or recycled, reducing the food industry's environmental impact. Composting and waste-to-energy solutions boost the industry's environmental responsibility. Sustainable food consumption, waste management, waste reduction, circular supply chains, and green practices can help stakeholders create a more resilient and environmentally friendly food system.

Personalized medicine leverages patient-specific biological data to tailor prevention, diagnosis, and treatment. Biomarkers are critical for enabling this precision approach. However, biomarker development faces challenges in discovery, validation, and robust modelling, often requiring extensive labelled data. Machine learning (ML) methods like few-shot and zero-shot learning offer potential solutions by enabling model generalization from limited examples. This chapter provides comprehensive exploration of biomarker types and applications and how few-shot and zero-shot techniques could enhance biomarker prediction tasks. Few-shot learning shows promise for biomarker discovery and validation by transferring knowledge from established biomarkers. Zero-shot learning provides opportunities to detect novel biomarker candidates unconstrained by predefined labels. While nascent, few-shot and zero-shot learning present intriguing paradigms for more efficient biomarker modelling, which could accelerate progress towards personalized medicine.
