El reciente Premio Princesa de Asturias de Comunicación y Humanidades ha recaído en Studio Ghibli “por haber transformado excepcionalmente la creatividad en conocimiento y comunicación”.

El galardón sirve para recordar algo que muchos espectadores ya sabían desde hace años: que sus películas no son solo historias bonitas, sino una forma distinta de mirar el mundo. A lo largo de décadas, el estudio de animación japonés ha creado un imaginario propio que ha marcado a varias generaciones, no tanto por lo que cuenta sino por cómo lo cuenta.

La fantasía como herramienta

La obra de Hayao Miyazaki, director, cofundador de Ghibli y probablemente su nombre más conocido, es una manera de hacer cine donde la fantasía no es evasión, sino una herramienta para entender mejor la realidad. Sus historias funcionan con una lógica más abierta, más intuitiva. No hace falta entenderlo todo para sentir que ese mundo es real. Una de las claves de ese estilo está en cómo construyen sus mundos.

En Mi vecino Totoro, por ejemplo, la historia de una familia que, en el Japón de la posguerra, comienza a interactuar con una criatura, nadie explica qué o quién es Totoro ni de dónde viene. El personaje es tan ambiguo como real. Aparece, y lo aceptamos, bien sea una deidad sintoísta o una imaginación infantil. Forma parte del paisaje igual que los árboles y la casa familiar. Lo mismo sucede en El viaje de Chihiro, donde la protagonista, en medio de una mudanza, entra en un mundo lleno de normas extrañas que nunca se explican del todo. Y, sin embargo, lo aceptamos. Hay cosas que van más allá de la lógica.

La magia en Studio Ghibli tampoco funciona como en otras historias. No es un poder para dominar o vencer, sino una forma de relacionarse. En El castillo ambulante, la fortaleza móvil del título, en su inexplicable funcionamiento, sirve de representación física de la inestabilidad emocional y agente transformador de su dueño. En La princesa Mononoke o Nausicaä del Valle del Viento, lo fantástico está profundamente conectado con la naturaleza. Los dioses, los espíritus o los ecosistemas no son decorado: son el centro del conflicto.

Las películas del estudio hablan, una y otra vez, de la relación entre los seres humanos y su entorno. Pero lo hacen sin sermones. No hay discursos directos ni moralejas evidentes. Lo que hay es aprendizaje, personajes que se equivocan, que dudan, que intentan entender.

Por eso es tan importante el tipo de protagonistas que aparecen en estas historias. Muchas veces son niñas o jóvenes en proceso de crecimiento, como Chihiro o las hermanas Satsuki y Mei de Mi vecino Totoro. No son heroínas clásicas que salvan el mundo, sino personas que aprenden a habitarlo. Su fuerza no está en vencer, sino en comprender, en cuidar, en establecer vínculos.

Esa idea conecta con otra de las características más reconocibles del estudio: la importancia de lo cotidiano. En las películas de Ghibli, cocinar, limpiar, trabajar o viajar tienen tanto peso como cualquier elemento fantástico. No son momentos de transición, sino parte esencial de la historia. Gracias a eso, la magia no aparece como algo lejano. Está en los pequeños gestos, en los silencios, en la forma en que los personajes se relacionan con su entorno. Lo extraordinario no rompe lo cotidiano: convive con él.

El papel de los recuerdos

Pero no se puede hablar de Ghibli sin mencionar también la figura del director Isao Takahata, otro de los cofundadores, que aportaba una mirada muy distinta.

Si Miyazaki explora la realidad a través de la fantasía, Takahata se acercaba más a ella a través de los recuerdos y de la consciencia del pasado. Y lo hacía sin suavizarla. En La tumba de las luciérnagas, la Segunda Guerra Mundial se muestra sin épica ni heroicidad. Es una experiencia dura, cotidiana, que golpea especialmente a los más vulnerables. No hay victimismo, pero tampoco consuelo fácil; solo una mirada honesta sobre lo que la violencia provoca.

Esa sensibilidad aparece también en Recuerdos del ayer, donde Takahata convierte la memoria en el verdadero centro de la narración. La película no necesita grandes conflictos: le basta con observar cómo los recuerdos de la infancia moldean la identidad adulta de Taeko, su protagonista. Algo parecido ocurre en El cuento de la princesa Kaguya, quizá su obra más poética y estéticamente única, donde la belleza de la vida coexiste con la pérdida y la imposibilidad de detener el paso del tiempo.

Películas que no se acaban

Esa convivencia entre lo fantástico y lo realista es lo que hace de Studio Ghibli algo único. No es solo un estudio de animación, sino un espacio donde distintas formas de entender el mundo dialogan entre sí.

En el caso de Miyazaki, su cine transmite una sensación de calma que a veces puede engañar. Sus películas son tranquilas, incluso luminosas, pero no necesariamente optimistas. En ellas hay conflictos que no se resuelven del todo, heridas que no desaparecen, como si fuesen un comentario directo a la realidad. Y, sin embargo, ahí está su fuerza. No ofrecen respuestas cerradas, sino formas de mirar, de estar en el mundo. Por eso, con el paso del tiempo, esos filmes no se agotan: siguen acompañando a quienes las ven porque dejan espacio para volver a ellas, para entenderlas de otra manera.

El reconocimiento a Studio Ghibli no premia solo una colección de películas inolvidables. Reconoce una forma de contar historias que apuesta por la sensibilidad, la empatía y la capacidad de asombro. En un momento en el que todo parece necesitar explicación, sus mundos nos recuerdan algo más simple e importante: que a veces basta con aprender a mirar.

La lamprea aún vive en el Guadalquivir

Source: The Conversation – (in Spanish) – By Miguel Clavero Pineda, Científico titular CSIC, Estación Biológica de Doñana (EBD-CSIC)

La lamprea marina (Petromyzon marinus) se encuentra en declive en España, donde se considera una especie en peligro crítico de extinción. La situación es especialmente preocupante en los ríos sureños, en los que ha sido registrada muy pocas veces en las últimas décadas, hasta el punto de que prácticamente se la consideraba extinta en el río Guadalquivir. Hasta ahora.

Acabamos de capturar una lamprea adulta de casi un metro de longitud en la Rivera de Huelva, uno de los principales afluentes del Bajo Guadalquivir (posteriormente, fue liberada). El hallazgo pone de manifiesto la importancia de los pocos tramos fluviales que aún conservan la conexión con el mar, fundamentales para estos animales. También pone el foco sobre la necesidad de mejorar nuestro conocimiento sobre peces migradores, uno de los grupos de animales más amenazados en España y en todo el mundo.

Malos tiempos para ser un pez migrador

Los peces anádromos nacen en los ríos y tienen un periodo de crecimiento en el mar, por lo que necesitan moverse libremente entre ambos ambientes. Son particularmente sensibles a la fragmentación de ríos por la construcción de barreras (como presas y azudes), ya que el bloqueo de las rutas migratorias hace que pierdan el acceso a las zonas de reproducción.

En el Guadalquivir, la presa de Alcalá del Río, a pocos kilómetros aguas arriba de Sevilla y en funcionamiento desde 1931, hizo que la mayor parte de la cuenca perdiese la conexión con el mar. La peor parte de los impactos generados se la llevaron peces migradores como el sollo (Acipenser sturio), al que hoy llamamos esturión, y el sábalo (Alosa alosa).

En la década de 1970 la lamprea ya se consideraba una especie rara en el Bajo Guadalquivir. Los registros posteriores se cuentan con los dedos de la mano, el último de ellos en 2014.

Sin embargo, vecinos de Guillena, localidad situada a orillas de la Rivera de Huelva, nos contaron que en torno a 1980 podían pescarse muchas lampreas. Es por tanto probable que la escasez de registros de lamprea se deba, al menos en parte, a la falta de cultura culinaria asociada a la especie en el sur de España. De hecho, nos dijeron que las lampreas se solían coger por el simple gusto de la captura, porque “ese pez tan raro” no lo comían.

En el Bajo Guadiana sí existe una explotación comercial de la lamprea debido a su gran valor en la gastronomía portuguesa. Es por esto que, desde hace años, se dedican importantes esfuerzos a su estudio y monitorización, algo que no se hace en el Guadalquivir. Además, estas pesquerías dirigidas a la especie dan lugar a capturas más frecuentes y trazables.

Aún así, la lamprea también se ha convertido en un animal extraordinariamente escaso en el Bajo Guadiana, hasta el punto de que los pescadores portugueses se quejan de que ya casi no vale la pena salir a pescarla.

Un ciclo complejo

La vida de la lamprea sigue un ciclo fascinante. Los individuos reproductores, como el capturado en la Rivera de Huelva, remontan los ríos buscando lugares apropiados para el desove. Hacen nidos en zonas de arena, en los que eliminan las piedras, moviéndolas con su boca en forma de ventosa.

De las puestas nacen larvas que, rápidamente, se entierran en sedimentos arenosos, donde viven filtrando agua para alimentarse. Cuando acaba esa fase filtradora, que puede durar más de cinco años, las larvas sufren una metamorfosis durante la que, por primera vez, desarrollan ojos funcionales, una boca succionadora repleta de dientes córneos y una lengua raspadora.

Estas lampreas juveniles abandonan la arena y viajan al mar. Allí se alimentan como parásitos de otros peces, a los que se aferran con la ventosa que forma su boca. En el Mediterráneo se les ha visto alimentándose de peces tan grandes como el pez luna (Mola mola) o la manta de espina (Mobula mobular).

Después de entre dos y tres años de vida en el mar, las lampreas dejan de comer y emprenden su regreso a los ríos para reproducirse.

La reproducción de la lamprea nunca se ha descrito en la cuenca del Guadalquivir, pero el tramo en el que ahora la hemos detectado podría tener las condiciones necesarias para albergarla, por sus grandes lechos de arena y aguas permanentes. De hecho, puede haber sido un lugar tradicional de reproducción, pero nadie ha estudiado esta posibilidad. Lo que sí es evidente es que en toda la cuenca del Guadalquivir quedan pocos lugares, si es que queda alguno, tan adecuados para la reproducción de la especie.

Un tramo excepcional y amenazado

El tramo de la Rivera de Huelva que queda aguas abajo del embalse del Gergal, del que se toma el agua que abastece al área metropolitana de Sevilla, es excepcional por ser el principal ecosistema fluvial de la cuenca del Guadalquivir que aún mantiene contacto directo con el estuario y, a través de él, con el mar.

En ese tramo coexisten anguilas, llegadas del mar, y lisas (llamadas albures en la zona), que se mueven entre este, el estuario y el río, con especies típicamente fluviales como el barbo, el camarón de río y hasta tres especies de náyades –grandes y muy amenazadas almejas de agua dulce–.

Este es seguramente el tramo más importante en toda la cuenca del Guadalquivir para la conservación de los peces y otra fauna acuática. Pero las figuras de protección de ríos, como las Reservas Naturales Fluviales, suelen establecerse en zonas de montaña, protegiendo tramos de río de aguas limpias y bien oxigenadas, que recorren bonitos paisajes con pocos impactos. Pero eso no implica que sean los más importantes para la conservación de la biodiversidad.

A pesar de sus indudables valores, el tramo bajo de la Rivera de Huelva enfrenta numerosas amenazas, entre las que destacan una nutrida representación de especies invasoras. Una especialmente preocupante es el siluro (Silurus glanis), capaz de comerse los elementos más valiosos de esta zona, como la anguila y, ahora lo sabemos, la lamprea.

La porción de la Rivera de Huelva que queda accesible a los peces migradores podría no ser suficiente para garantizar su conservación o favorecer su recuperación en la cuenca del Guadalquivir. Lo que vemos hoy es un residuo ínfimo de lo que debía ser una frecuente y abundante presencia en ríos y arroyos, un escenario que ha desaparecido de la memoria colectiva.

El descubrimiento de la lamprea en el Guadalquivir es una buena noticia. Sería todavía mejor si empezáramos a recuperar para los peces migradores parte de la enorme cantidad de hábitat que les hemos quitado.

En la cuenca del Guadalquivir sería fundamental eliminar las barreras que forman las presas de Alcalá del Río y Cantillana, estructuras antiguas, pequeñas, con una exigua producción eléctrica, pero con un impacto gigantesco. Sin esas barreras, el tramo bajo de la Rivera de Huelva no sería tan excepcional y daríamos una oportunidad a varias especies de peces que están a punto de desaparecer, de los ríos y de nuestra memoria.

Donald Trump’s chaotic mess: When U.S. power serves the ‘sultan,’ global rules erode

Source: The Conversation – Canada – By Christopher Collins, Fellow, Geopolitics, Cascade Institute, Royal Roads University

Historically, the United States hasn’t always been easy to deal with, but it was consistent. Even countries that disagreed with American policies knew there was a logic underlying its actions, and this predictability gave the country some credibility.

But now, under U.S. President Donald Trump’s second administration, American foreign policy has become haphazard and contradictory, driven by a leader who believes his ability to exercise power around the world is constrained only by his own morality.

This is new and, for observers around the world, perplexing. As Canadian Prime Minister Mark Carney recently said: “Washington has changed. There is almost nothing normal now in the United States.”

Trump maelstrom

Some, like U.S. Vice President JD Vance, are labouring to erect a retroactive, pseudo-intellectual scaffolding around this chaotic mess, seeking to frame it as a coherent doctrine. But it’s become increasingly clear there’s no grand plan, just a Trumpian maelstrom of impulsive reactions, extractive transactions and personal grudges that shift with the news cycle.

To understand this political dysfunction, a German thinker from more than 100 years ago, Max Weber, offers a helpful guide.

Most famous today for his theory of “the Protestant work ethic,” Weber’s writing also explored the concept of “patrimonialism.”

This is a system of governance in which a ruler treats the state as personal property, governs by whim and uses the state’s resources to reward cronies and enrich family. Drawing largely on his understanding of the Ottoman Empire, Weber called the most extreme form of this system “sultanism.”

Reading Weber today, it seems the best description of how the U.S. engages the wider world could be termed “sultanism with American characteristics.”

Loyalty over experience

Consider Iran. Following the start of Operation Epic Fury, the Trump administration cycled through so many conflicting war aims that CNN was able to assemble a montage of the contradictions.

Senior administration officials worked feverishly to build a strategy around the operation, but it soon became clear that this “war of choice” was started based on little more than the president’s whim.

Weber’s framework extends to the people around Trump. In sultanistic systems, staff are selected based on loyalty, not merit, and serve the ruler, not the state.

As Weber wrote, this leads to “an administration and a military force which are purely personal instruments of the master.”

We see this pattern vividly illustrated by the Trump administration’s approach to staffing senior roles, including those leading high-stakes diplomatic negotiations.

Look at Steve Witkoff, a real estate developer and longtime Trump friend with no foreign policy experience, who has served as the administration’s lead envoy on some of the most sensitive negotiations in the world.

Or Jared Kushner, the president’s son-in-law, who, despite having no background in foreign policy, was entrusted with key roles in Middle East diplomacy, while his investment firm pursues deals with the same Gulf states he is negotiating with on behalf of his country.

Serving the sultan

These are not appointments that a merit-based system would produce. But right now in America, officials serve the sultan, not the republic, which is why their speeches are regularly given for an “audience of one.”

Furthermore, in seeking the sultan’s favour, appointees regularly debase themselves on television, such as when Kevin Warsh, Trump’s pick to be the next head of the Federal Reserve, refused to admit Trump lost the 2020 election.

This sultanistic pattern of rewarding loyalty and punishing defiance is expanding. Federal disaster relief, long treated as a non-partisan obligation of the government, has become a stark illustration of this logic.

Since the start of his second term, Trump has approved just 23 per cent of disaster funding requests from blue states, compared to 89 per cent for red states. In some cases, the conditionality for disaster aid has been made explicit: for example, in 2025, as fires ravaged Los Angeles, Trump threatened to withhold aid unless California enacted voter ID laws — a condition with no relationship to disaster recovery.

This fear of punishment also helps explain why, fearing for their businesses, many media companies are bowing to “the court of King Trump.”

‘Orgy of corruption’

Finally, Weber’s framework sheds light on what may be the most defining feature of the Trump administration: a blurring of the lines between public office and private enrichment. Under sultanism, the distinction between the ruler’s personal wealth and the state’s treasury is, at best, notional.

Trump and his team have governed accordingly, with perhaps the most egregious example being hundreds of millions of dollars of insider trading around the Iran war. In a healthy democracy, this “orgy of corruption” would be investigated and prosecuted. But in a patrimonial system this is simply how things work: the state exists to serve the ruler and his inner circle.

This is what the world must now manage. A sultanistic system does not respond to appeals to shared values or long-standing agreements. It responds to leverage, personal relationships with the ruler and transactional incentives.

Policymakers and business leaders increasingly understand they are dealing with a court that rewards fealty and punishes defiance. That’s why the Swiss gave Trump a gold bar in exchange for lower tariffs, and why the Qataris gave him a “palace in the sky.”

In 2026, appeals to shared democratic values or common national interests are pointless; bring the sultan something he wants or face punishment. Weber helps explain why.

Dissuasion algorithmique, rétention : l’IA fait-elle passer la cybersécurité à une nouvelle ère ?

Source: The Conversation – France in French (2) – By Christine Abdalla Mikhaeil, Assistant professor in information systems, IÉSEG School of Management

L’entreprise états-unienne Anthropic, spécialisée en intelligence artificielle générative, a pris début avril la décision de geler la diffusion publique de l’un de ses modèles récents, baptisé « Mythos ».

Selon un communiqué de la société, cette décision découle d’une puissance de calcul et d’une capacité de raisonnement jugées trop « offensives ». Anthropic a choisi de ne partager son modèle qu’avec une coalition de géants technologiques (Apple, Amazon Web Services, Cisco, Google, Microsoft, etc.) dans le cadre du projet Glasswing. Le but annoncé est d’utiliser Claude Mythos Preview pour détecter des vulnérabilités dites « zero-day » (c’est-à-dire inconnues et n’ayant aucun correctif connu) et sécuriser proactivement les logiciels critiques… avant que des acteurs malveillants n’exploitent ces failles.


Les grands modèles de langage savent déjà coder depuis quelques années, mais la presse spécialisée documente désormais un saut plus préoccupant. Des systèmes d’intelligence artificielle (IA) peuvent identifier des vulnérabilités réelles dans des logiciels critiques. Les autorités, comme l’Agence nationale de la sécurité des systèmes d’information (Anssi), soulignent la capacité des systèmes d’IA à automatiser les attaques.

Les enjeux de la diffusion massive de tels modèles, Mythos compris, dépassent largement le cadre technique. Une cyberattaque d’envergure, automatisée par une IA, pourrait paralyser des systèmes financiers ou logistiques en quelques secondes, avec un coût de remédiation se chiffrant en milliards d’euros. Les enjeux sont aussi sociétaux et de santé, puisque nos hôpitaux, nos réseaux énergétiques et les autres systèmes critiques reposent sur des couches logicielles souvent anciennes, vulnérables à des « attaques de zero-day » désormais générées à la chaîne.

Dans ce contexte, des IA ultraperformantes, comme Mythos, peuvent-elles contribuer à une forme de « dissuasion algorithmique » ? Celle-ci repose sur un principe simple : détecter et neutraliser ses propres vulnérabilités critiques plus vite que n’importe quel attaquant humain ou automatisé – y compris lors d’une attaque – si rapidement que l’attaque en devient inutile ou trop coûteuse.

La rétention de ce modèle par une ou des entreprises privées états-uniennes rouvre également la question de la souveraineté numérique à l’échelle mondiale.

Les systèmes d’IA facilitent les cyberattaques

Historiquement, la cybersécurité repose sur une asymétrie fondamentale : l’attaquant n’a besoin de trouver qu’une seule faille de sécurité, tandis que le défenseur doit toutes les combler dans une forme de course contre la montre.

L’intégration de systèmes d’IA renforce les capacités des attaquants, en premier lieu parce qu’un modèle comme Mythos peut scanner des millions de lignes de code en quelques minutes, là où un humain passait des semaines à analyser le code source d’un logiciel pour y déceler une erreur de mémoire. C’est ce que l’on appelle l’« automatisation de la reconnaissance ».

De plus, l’IA permet le phishing de haute précision, c’est-à-dire des messages frauduleux (le phishing classique) mais plus crédibles, sans fautes d’orthographe, dans n’importe quelle langue et ultrapersonnalisés pour tromper l’utilisateur. L’Anssi alerte d’ailleurs sur l’usage de l’IA générative pour briser les barrières linguistiques et psychologiques traditionnelles qui rend les « pare-feux humains » – c’est-à-dire la vigilance et l’esprit critique des lecteurs – de plus en plus obsolètes.

Enfin, des malwares peuvent désormais réécrire leur propre code en temps réel pour échapper à la détection « par signature ». Cette méthode classique des antivirus consiste à identifier un virus par son « empreinte » (un code déjà connu et répertorié). En changeant constamment de forme (exploitation polymorphe), le malware devient invisible pour ces outils traditionnels.

L’IA pour la cyberdéfense

En miroir, l’IA améliore aussi les capacités de cyberdéfense, grâce à des analyses causales, qui permettent de modéliser les relations entre événements, ainsi qu’en accélérant l’identification d’anomalies par une surveillance automatisée et la priorisation de leurs corrections. Ainsi, un système d’analyse IA a permis en janvier de découvrir 12 failles de sécurité dans OpenSSL, un logiciel essentiel à la protection des communications internet mondiales.

Mythos semble également déjà participer à cette automatisation, et Firefox affirme déjà avoir identifié et réparé 271 vulnérabilités grâce à ce logiciel, ce qui suggère que Mythos excelle effectivement dans la détection de vulnérabilités lorsqu’il a accès au code source.

En revanche, rien ne prouve pour l’instant que Mythos puisse, sans accès au code source et sans intervention humaine, compromettre de manière autonome n’importe quel logiciel fermé.

De plus, des analyses suggèrent que des capacités comparables seraient déjà reproductibles à partir de modèles publics, remettant en cause l’efficacité de cette rétention. Ainsi, Mythos ressemble aujourd’hui davantage à un analyste de sécurité surpuissant, capable d’identifier des failles et de proposer des pistes d’exploitation, qu’à une entité autonome de cyberattaque universelle.

Ce qui inquiète vraiment, ce n’est pas seulement que Mythos sache mieux coder ou mieux tester du code : c’est qu’il semble abaisser le coût, le temps et le niveau d’expertise nécessaires pour découvrir et enchaîner des failles, donc potentiellement accélérer aussi bien la défense que l’attaque.

Vers un nouvel équilibre de la « dissuasion algorithmique » ?

Dans ce contexte, la notion de « dissuasion algorithmique » (algorithmic deterrence en anglais) émerge. Elle peut être comprise par analogie avec la dissuasion nucléaire : il ne s’agirait plus seulement de se protéger, mais de posséder une capacité de réponse et de détection si rapide que l’attaque en devient inutile ou trop coûteuse.

Contrairement au domaine nucléaire, la dissuasion algorithmique repose sur le renforcement des mécanismes défensifs (plutôt que de réponse) : détection accélérée des intrusions, analyse des causes et simulation d’attaques pour boucher les failles avant qu’elles ne soient exploitées.

Avant l’ère de l’IA, la dissuasion algorithmique était plus limitée : les équipes de sécurité réalisaient des tests d’intrusion, une méthode d’évaluation de la sécurité qui repose sur la simulation de cyberattaques, pour identifier les ports ouverts et failles connues, pour enclencher leur correction.

Aujourd’hui, on l’a vu, l’IA peut renforcer les mécanismes défensifs et donc la dissuasion. Mais, dans le meilleur des cas, une IA de défense permet de réduire le coût de la protection et d’augmenter la probabilité qu’un attaquant soit repéré ou neutralisé avant d’atteindre son objectif.

La dissuasion algorithmique reste donc fragile. Même à l’ère de l’IA, elle dépend beaucoup des pratiques des acteurs opérationnels (agences de cybersécurité, armées, entreprises), de la qualité et de la modernité des systèmes hérités qu’ils doivent protéger et intégrer, des stratégies nationales et militaires mises en œuvre par les États ainsi que des dispositifs de gouvernance qui définissent les règles, les responsabilités et les mécanismes de contrôle de l’IA.

Le dilemme de la rétention d’outils de dissuasion : sécurité contre transparence

Ne pas rendre disponibles au grand public certains modèles peut sembler responsable, car cela évite de publier des capacités offensives qui seraient immédiatement détournées. Mais cette rétention concentre le pouvoir technologique entre quelques mains et réduit la transparence scientifique.

Le débat rejoint ici celui du cadre l’AI Act européen, qui impose déjà des obligations de transparence, de traçabilité et de documentation pour les modèles d’IA d’usage général, tout en cherchant à concilier innovation, sécurité et protection des secrets industriels.

L’opacité des modèles d’IA limite leur auditabilité, entrave le développement de contre-mesures appropriées et concentre le pouvoir technique entre quelques acteurs principalement américains, au détriment de la recherche ouverte et de la gouvernance démocratique. Cette critique s’inscrit dans une littérature académique plus large montrant que l’opacité des systèmes d’intelligence artificielle compromet leur reproductibilité, leur auditabilité et, in fine, leur valeur scientifique.

Motown’s Black women songwriters and producers were the invisible architects behind the pop music juggernaut

Source: The Conversation – USA (2) – By Margena A. Christian, Emeritus professor, University of Illinois Chicago

Sylvia Moy was a trailblazing Motown songwriter. L. Busacca/WireImage for Songwriter’s Hall of Fame

During the 1960s, in a country divided by racial strife, the music of Berry Gordy Jr.’s Motown Records helped bring people together.

Motown was noted for star performers like Mary Wells, The Miracles, The Supremes, The Temptations, Martha Reeves and the Vandellas, Marvin Gaye and Stevie Wonder. But, behind the scenes, a talented group of lesser known women were driving the hits in Hitsville U.S.A.

I’m a scholar of popular culture and author of the biography “It’s No Wonder: The Life and Times of Motown’s Legendary Songwriter Sylvia Moy.” Researching my book inspired me to find other women who contributed to the Detroit label’s era of chart dominance and helped change the music industry, despite going largely unrecognized for their efforts.

I listened to Motown growing up, but it wasn’t until 2021, while sitting at home during the pandemic, that I discovered Moy’s history as the lyricist for Stevie Wonder and how she helped revive his early career.

Because Moy died in 2017, I wasn’t able to speak with her for the book. Instead I researched her life by reading countless interviews she gave, along with talking to her former colleagues at Motown, family and ethnomusicologists, who are scholars that study music through the lens of culture.

Architect of the early sound

When Gordy was organizing his company, Janie Bradford was one of the original five founding members who arrived in 1958. She was the label’s first secretary and its first female songwriter after co-writing, with Gordy, the song “Money (That’s What I Want).” That song was released on Tamla Records in 1959 and performed by Barrett Strong. When Motown was incorporated the following year, the song became the label’s first hit record on the R&B chart and Billboard Hot 100.

Later, Bradford co-wrote “Contract on Love” for Wonder and “Too Busy Thinking About My Baby,” first recorded by The Temptations and later, Marvin Gaye. Bradford, who later became Motown’s director of writer’s relations, teamed up with pianist Richard “Popcorn” Wylie in the early 1960s to form Janard, a small production company.

Bradford’s collection of poetry is what captured Gordy’s attention, so he encouraged her to be a songwriter. Her witty lyrics told stories about situations that most anyone could relate to – namely, money and love – blended with up-tempo, thumping beats.

Laying the foundation as a producer

Another key figure who paved the way with the Motown sound was Raynoma Gordy Singleton, who was married to Berry Gordy Jr. from 1960 to 1964. She organized Motown during its beginnings by completing the necessary paperwork to incorporate the business. Known as “Miss Ray” to some and “Mother Motown” to others, she located the legendary house at 2648 West Grand Boulevard that became the Motown headquarters and, decades later, the Motown Museum.

In her role as the label’s first executive vice president, she established a tape library. A piano virtuoso and singer, the Cass Technical High School graduate wrote that she was able to play all string and wind instruments. As a result, she became the company’s first female arranger and producer by putting together its first backup vocal group, the Rayber Voices, in 1958.

“Producing records was where the action was controlled – and where the money was to be made,” she wrote in her memoir, “The Untold Story: Berry, Me, and Motown,” which aimed to reclaim her place in the Motown echelon.

During the 1960s, women weren’t considered producers because of broader biases and norms in the male-dominated music industry. Even so, Miss Ray got credit for producing Jimmy Ruffin’s song “Don’t Feel Sorry for Me” in 1961.

Earning a producer’s credit was a sign of legitimacy. Most producers received a songwriting credit and determined who received credit in the liner notes for their contribution to the recording.

While women mostly worked in administrative roles at Motown, there still weren’t any female full-time, in-house songwriters and producers. Like the rest of the music industry back then, Motown’s internal structure was patriarchal with those positions.

The first certified female songwriter and producer

Yet this imbalanced gender dynamic at Motown didn’t stop Sylvia Moy.

There hadn’t been any women producers behind significant, popular songs at Motown until Moy arrived, according to interviews I conducted for her biography.

Motown was at its peak in 1964. Demand for new songs was intense. When the label’s executives realized how skillfully the two audition songs Moy performed were composed, they decided that her future was in songwriting instead of singing.

Discovered by William “Mickey” Stevenson and Marvin Gaye, Moy was hired as the first female in-house songwriter, competing with eminent colleagues like Smokey Robinson, Norman Whitfield and the songwriting trio Holland-Dozier-Holland who wrote 10 of the Supremes’ chart-topping singles. Moy made more history in 1965 after co-writing and co-producing Stevie Wonder’s “Uptight (Everything’s Alright).”

While she received the songwriting credit and helped revive the teenaged Wonder’s career, Moy wasn’t given the producer’s credit, unlike her two male counterparts, Stevenson and Henry “Hank” Cosby.

A lack of recognition stymied Moy’s career opportunities. If a songwriter or producer wasn’t credited, their value could not be validated or established, which made it harder for them to find work at other record labels.

According to my research, Moy revealed that she never got producer credit for any of her work while at Motown. This is why her legacy was buried for so long.

Other tunes she wrote for Wonder were “I Was Made to Love Her,” “My Cherie Amour” and “With A Child’s Heart,” co-written with Vicki Basemore. Moy also wrote Marvin Gaye and Kim Weston’s “It Takes Two” and The Isley Brothers’ “This Old Heart of Mine (Is Weak For You).” Though songwriter Eddie Holland told me he gave her a co-writing credit for “This Old Heart of Mine,” Moy’s name was not listed on the record, only Holland-Dozier-Holland.

Interviews I conducted with Moy’s family members and research from an ethnomusicologist suggest she was even an uncredited co-writer for Wonder’s “Signed, Sealed, Delivered (I’m Yours),” his first song as a solo producer, and The Temptations’ “Ain’t Too Proud to Beg.”

However, Holland denied this claim in an interview with me, though he also admitted that the song’s late co-writer and producer, Norman Whitfield, presented him with the lyrics, and he wasn’t sure where they came from.

Full credit along with creative control

In 1968, Valerie Simpson became Motown’s first female songwriter to also receive a producer credit. This possibly happened because her songwriting partner was her husband, Nickolas Ashford.

Other famous female songwriters like Carole King, Ellie Greenwich and Cynthia Weil also had a prominent husband in the music industry. Sylvia Moy did not, which made what she did unprecedented.

Simpson told Billboard in 2023 that the credit was difficult to attain because so few women were producers back then. It finally happened with the Tammi Terrell and Marvin Gaye song “Ain’t Nothing Like The Real Thing,” with Simpson getting credit for co-writing, co-producing and performing background vocals along with Ashford.

This was their third hit tune by Terrell and Gaye, who also recorded “Ain’t No Mountain High Enough” and “Your Precious Love,” in 1967. The following year, they had another hit with “You’re All I Need to Get By,” which Ashford and Simpson also co-wrote, co-produced and did background vocals on.

‘Ain’t Nothing Like the Real Thing’ was performed by Marvin Gaye and Tammi Terrell. Valerie Simpson co-wrote and co-produced the song along with her husband, Nickolas Ashford.

Simpson became the first Black woman to be inducted into the Songwriters Hall of Fame in 2002. Moy became the second in 2006.

Though female songwriters and producers continue the fight for inclusion in the recording studio, the doors were opened by the tenacious women of Motown. It is because of them that future generations of female creatives know what is possible.

Lower East Side street named for ‘King of Comics’ Jack Kirby, a nod to one of the countless kids of immigrants who shaped the genre

The gesture may lack the explosive drama of a rooftop fight or the tension of a car chase, but on May 11, 2026, a street sign honoring a legendary comics creator will be unveiled in Manhattan’s Lower East Side.

After a lobbying effort by comics expert Roy Schwartz, the New York City Council in December 2025 approved the naming of a block of Essex Street between Delancey and Rivington streets in honor of Jack Kirby.

Kirby, born Jacob Kurtzberg in 1917 to Jewish immigrants, spent roughly the first 40 years of his life in New York, aside from a stint serving in the military during World War II. Before enlisting, he’d already embarked on a career as a comics artist. He went on to become a key figure during the medium’s golden age, a period that most scholars and fans agree began with the creation of Superman in 1938 and ended with the implementation of the Comics Code Authority in 1956, which heavily restricted content until enforcement weakened in the 1970s.

Though you may not have heard of Kirby, you’d have to deliberately avoid pop culture to miss his most influential creations: Captain America, the Fantastic Four, X-Men, Thor, Hulk, Iron Man and Black Panther.

For my part, however, as a scholar of American Jewish immigration history – and as a lifelong comic book fan – I hold a place of reverence for the man known as the “King of Comics.”

Jewish American history, immigration history, the history of New York City and the origins of the comics industry are inextricably linked. New York played a starring role in the golden age of comics. And like Kirby, many of the genre’s most famous artists were Jewish.

Jewish immigrants put pen and ink to paper

Comics found a wide audience in New York City during their early years in the late 19th and early 20th centuries, from early newspaper strips like “The Yellow Kid” and “Abie the Agent” to later ones like “Little Orphan Annie.”

As World War II drew to a close in the summer of 1945, there was a citywide newspaper delivery strike, leaving many New Yorkers desperate for news and entertainment – so much so that Mayor Fiorello LaGuardia took it upon himself to read the Sunday comic strips over the radio, performing them with characteristic vigor and enthusiasm.

Among the first publications that would today be recognizable as “comic books” were compilations of these early newspaper strips, assembled by newsprint salesman and Jewish New Yorker Max Gaines. Gaines, born Maxwell Ginzburg, compiled various comic strips into neatly packaged, inexpensive entertainment for the masses, helping pioneer the saddle-stitched comic book – thin, stapled magazines that would become the primary format for superhero stories.

As the superhero genre took off in the late 1930s, other publishers emerged from Jewish New York. Harry Donenfeld and Jack Leibowitz, in partnership with Malcolm Wheeler-Nicholson, created Detective Comics and Action Comics, which helped establish the company later known as DC Comics.

In addition to early publishers, many pioneering comics artists were raised in New York City as the children of Jewish immigrants, including Marvel Universe architect Stan Lee and his brother, Larry Lieber; Will Eisner, creator of “The Spirit” and co-creator of “Sheena: Queen of the Jungle”; and Al Jaffee, a longtime contributor to Mad Magazine.

An ode to the Lower East Side

In Jack Kirby’s comics, the city shines through.

The Fantastic Four – the superhero squad that Kirby created with Stan Lee – operates out of midtown Manhattan’s fictional Baxter Building, which Kirby modeled after the city’s mid-century skyscrapers.

Kirby also based the character of Ben Grimm – The Thing – on himself, mining his own life to write Grimm’s backstory. Grimm’s home is on the fictional Yancy Street, a tribute to Kirby’s own working-class upbringing on the Lower East Side’s Delancey Street. The thoroughfare is rich with Jewish history and in close proximity to iconic businesses like Katz’s Deli and Russ and Daughters.

Another of Kirby’s most iconic characters was Steve Rogers – Captain America – which he co-created with Joe Simon.

A poor orphan from Brooklyn, Rogers attempts to enlist in the U.S. Army to fight the Axis powers during World War II, but is rejected as unfit for duty. He is later recruited into Project Rebirth, where he is transformed into a super-soldier after being injected with a serum designed to maximize human physical and mental abilities.

Captain America attracted legions of fans among American youth, many of whom saw themselves in the superhero. Though Rogers is Christian, his story of transformation from weakling to hero certainly spoke to young Jewish boys and men, who were often inaccurately portrayed in the media and press as intellectually superior but physically inferior.

Captain America, though fictional, is already recognized as a part of New York City history, and has a statue in Brooklyn, which was unveiled in 2016 with the inscription “I’m just a kid from Brooklyn.”

The city as a muse

Even comics created by artists outside New York City – like Ohio natives and Superman co-creators Jerry Siegel and Joe Shuster – are, by virtue of their content, still in many ways New York comics.

The glittering Metropolis in “Superman” is widely understood as a stand-in for New York; for example, in the April 1950 issue of Action Comics, the Statue of Liberty is said to appear in “Metropolis Harbor.”

If Metropolis is the bright, shining, optimistic view of the city, then Gotham, the home of Batman, reprises the city through a grittier lens.

Writer Washington Irving had first described New York as Gotham in the early 1800s. But by the time Batman came on the scene, the term had become less common in everyday speech, and DC Comics repurposed the name for the fictional Gotham City. Beyond the name, Gotham City’s architecture, bridges, boroughs and neighborhoods are an homage to New York.

By officially recognizing Jack Kirby, the city adds the artist to a distinguished roster of politicians, community activists and celebrities honored with street names.

Jack Kirby Way celebrates a legendary comics artist while also acknowledging the immigrant creators who helped shape the genre. It’s a fitting tribute: As much as the comics industry is indebted to the city, the city is indebted to the comics industry.

The American Revolution’s triumphant story of democracy and freedom overlooks loyalists who paid a steep price for allegiance to Britain

Source: The Conversation – USA – By Kimberly Nath, Dean of the School of Arts and Humanities, San Juan College

The announcement of the Declaration of Independence on July 4, 1776, in Philadelphia. Hulton Archive via Getty Images

On the eve of the American Revolution, Matthias Aspden made a decision that would change the trajectory of his life. A wealthy merchant from Philadelphia, Aspden carefully prepared to leave his home in March 1776 as rumors of revolution circulated. He drafted a will and appointed trusted friends to manage his property while he traveled to England.

As a loyalist, someone who wanted to remain loyal to the crown and the British empire, Aspden believed the war would be brief. Historians estimate that at the beginning of the war as many as one-third of all American colonists identified as loyalists. Aspden believed his departure would be temporary. Order, he assumed, would soon be restored, and he would permanently return within a few years.

But that wasn’t the case.

The American Revolution is often told as a triumphant story of democracy and freedom. But this narrative leaves out a significant group: the loyalist men and women who remained faithful to Britain and, as a result, lost their homes, property and sometimes their sense of belonging.

As a historian of the American Revolution who studies Philadelphia loyalists, I believe Aspden’s story offers a glimpse into an overlooked experience of the war.

A wealthy Philly merchant exiled in England

Born and raised in Philadelphia, Aspden was not a marginal figure. He was a Quaker merchant with extensive property holdings, including a home on Water Street, in what is now the Old City neighborhood, and land in Chester County outside Philadelphia.

When he left in 1776, he abandoned nearly everything he owned, believing he would return. As others celebrated independence that summer, Aspden quietly slipped away to London.

In England, reality set in. Exile was not just physical; it was deeply social and emotional. In Philadelphia, Aspden had been established. In London, he was one of tens of thousands of displaced loyalists trying to rebuild a life. He gravitated toward communities of fellow exiles. These networks offered some stability, but they could not replace what he had left behind.

Aspden’s letters to friends and family from this period reveal a man caught between hope and anxiety. He followed news from Philadelphia obsessively, requesting newspapers and updates from friends and business contacts. At one point, he described himself as “an idle man until I can return to America.” His words suggest both longing and uncertainty, as if his life were on pause.

By 1780, that uncertainty turned into fear.

A ‘traitor’ trying to come back home

Aspden began hearing about laws in Pennsylvania aimed at confiscating loyalist property. These laws required individuals accused of treason to appear in court and defend themselves. Aspden, still in England, could not do so. As a result, he was tried in absentia, declared a traitor and subjected to the state’s harshest penalties.

The consequences were devastating. In 1782, Aspden learned that all of his property had been confiscated and would be sold to aid the patriots in the American Revolution. An official commissioner of confiscation seized his Philadelphia home and wharf, which were worth thousands of pounds, along with his land in Chester County. Aspden, facing financial ruin, decided to return to Philadelphia to defend his name and his property.

In 1785, after nearly a decade abroad and with the war over, he crossed the Atlantic, hoping the new United States would restore his property under the terms of the peace treaty with Britain. Instead, he was met with rejection.

Pennsylvania officials informed him that individuals in his position were not protected. He had no legal claim to his property and, more shockingly, no rights as a citizen. While the peace treaty prevented further confiscation of loyalist property, his property was not restored.

The message was clear: Philadelphia was no longer his home.

One last trip to Philadelphia

Aspden left again, traveling through New Jersey and New York before securing passage back to England. Reflecting on his departure, he wrote of the pain of being forced from his “native country.” His brief return confirmed what he had feared. He had no home.

In the years that followed, Aspden sought compensation wherever he could. The American government offered nothing, so he turned to Britain. The Loyalist Claims Commission, established to reimburse those who had lost property during the war, eventually awarded him just over 1,100 pounds, a fraction of his estimated losses.

Aspden made one final visit to America in the early 1790s. By then, he had received a legal pardon and could travel without fear of arrest. But he still could not recover his property or successfully pursue compensation in American courts. Once again, he left – this time for good.

Heirs recover his fortune

Aspden died in England in 1824, having spent nearly 50 years in exile from the city he always considered home.

Decades after his death, his heirs pursued a legal claim in the United States against Pennsylvania, arguing that his estate had been unjustly seized. After years of litigation, the court ruled in their favor in 1848, awarding them over a half-million dollars – approximately US$20 million today. It was a remarkable reversal, but Aspden never saw justice.

His life raises difficult questions about loyalty, identity and belonging. Aspden did not see himself as disloyal to Philadelphia. To him, loyalty to the British Crown and loyalty to home were not opposites.

His story reminds us that the Revolution was not just a fight for independence. It was also a civil conflict that divided communities and reshaped lives. For every celebrated patriot, there were loyalists like Aspden and others who lost so much during the American Revolution.

Online hate groups sustain their messages by repeating powerful stories or routinely adding new allegations

Source: The Conversation – USA – By Yu-Ru Lin, Professor of Computing and Information, University of Pittsburgh

Studying the types of messages hate groups spew online helps researchers understand the groups’ persistence. Westend61/Westend61 via Getty Images

Hate communities often flourish online for years, raising the question of how they persist. My research team has found that powerful stories keep members of a hate group galvanized, either by repeating the story over and over or by constantly adding fresh accusations and interpretations to it.

I’m a computational social scientist who studies social and political networks. My colleagues and I uncovered these trends by examining 10 years of posts, reactions and participation patterns in Facebook groups that shared antisemitic and Islamophobic content. Our findings have been accepted at the 2026 International Conference on Web and Social Media.

First, we measured who was posting and how that related to engagement on a site. Groups in which a small number of people produced most of the content tended to attract more reactions and responses. Then we looked at subjects the group members discussed – religion, immigration, geopolitics – and the kinds of stories members told about those topics, such as describing an entire group of people as criminals or warning that certain types of people are secretly taking over a country’s way of life.

When we put these pieces together, we discovered some clear patterns. Messages posted by a few very active people were strongly associated with higher site engagement in the form of likes and shares in the near term. And repetition – espousing the same ideas again and again – was an effective tactic. We also found that when many users kept adding fresh accusations, conspiracy theories and explanations, a group tended to persist. Very uniform content that used the same framing led to less engagement over time.

Different communities seemed to be drawn to different messaging patterns. In Islamophobic groups, the most prolific posters tended to repeat a narrow, consistent set of messages. Often these were religiously framed posts that portrayed Muslims as morally condemned. In antisemitic groups, the most engaged members were more likely to impart a mix of narratives, from tales of victimization to conspiracy theories about public figures.

Why it matters

Our findings suggest that hate communities can sustain themselves in various ways, so efforts to moderate them should consider these variations. If a few voices drive the conversation, removing them could quiet the noise. If new stories constantly appear from many contributors, harmful ideas may survive even if a few key online accounts are taken down. Hate networks can persist even after social media platforms ban specific groups or accounts.

It is also important to understand how stories can make prejudice feel justified and emotionally compelling. Extremist stories may claim that a group is under attack, that outsiders are dangerous or subhuman, or that violence is the only way to stay safe. Groups seen as outsiders – such as immigrants – are common targets, and they may be described as an “invasion” that threatens the nation.

What other research is being done

Researchers are finding that extremist ideas are now spreading through looser networks where many voices contribute and messaging can vary widely. That could affect whether engagement in the future still depends on consistent repetition or novelty. Some investigators are also scrutinizing how harmful language, conspiracy theories and propaganda evolve over time.

What’s next

Another important direction is tracking how hate narratives are spread by public figures and influencers, how the narratives move between online platforms, and how they surface in offline groups and efforts to organize supporters, all of which can normalize harmful ideas. My group is starting to study how this amplification works: who shares which narratives and why, which kinds of people become bridges across different online platforms, and how those roles shape which messages spread.

The Research Brief is a short take on interesting academic work.

Canada is kicking its US booze habit as trade tensions persist

Source: The Conversation – USA (2) – By Andrew Muhammad, Professor of Agricultural and Resource Economics, University of Tennessee

One of the most visible ways that Canada responded to President Donald Trump’s tariffs was by sharply restricting U.S. alcohol sales. AP Photo/Jill Colvin

Almost a year and a half after President Donald Trump began slapping tariffs on nearly all U.S. trading partners, Canada’s pushback has reordered the economic relationship between Ottawa and Washington.

Canadians are pulling back on U.S. travel, boycotting U.S. goods and protesting in droves – further galvanized by Trump’s call for Canada to become the 51st U.S. state.

But the example of one sector in particular, U.S. alcohol, shows how quickly access to an important market can disappear – and how difficult it can be to regain.

From 2022 through 2024, Canada accounted for roughly 35% of U.S. wine exports, more than 15% of U.S. beer exports and as much as 13% of U.S. distilled spirits exports. Within just one year of Trump returning to office, Canada’s imports of U.S. alcohol cumulatively have plunged over 70%, thanks to a mix of both tariff and nontariff retaliatory measures.

It’s a sharp reversal from Canada’s traditional role as a top foreign destination for American beer, wine and spirits. That relationship reflected both long‑standing consumer preferences as well as geographic proximity and largely tariff‑free access through agreements like the North American Free Trade Agreement and its successor, the United States-Mexico-Canada Agreement.

As an agricultural economist working on trade issues related to alcohol, I see Canada’s alcohol sector as a textbook example of how market access for politically exposed goods can quickly unravel. And for American beer, wine and spirits producers – and for the farmers who grow the barley, grapes and corn that go into these products – the recent experience highlights how trade disputes often hit food products hardest. If a trade ban becomes entrenched, it opens a way for consumers to develop a taste for domestic as well as other foreign alternatives.

The Trump tariff shock

Before Trump’s tariffs and talk of Canada as the 51st U.S. state, U.S. alcohol occupied substantial shelf space in major alcohol-consuming provinces such as Ontario, British Columbia and Québec. In 2024, these exports to Canada constituted more than 20% of Canada’s alcohol imports, totaling US$744 million. For most U.S. producers, Canada served not only as a key export destination but as a stable and relatively low‑risk entry point into international markets.

That changed in February 2025, when Trump, citing a national security emergency, imposed 25% tariffs on Canada and Mexico. Those tariffs – which were overturned by the Supreme Court in February 2026 – marked the first time that law was used to authorize broad tariffs.

Canada responded by slapping retaliatory tariffs of 25% on roughly $30 billion of U.S. goods and signaling it would significantly expand countermeasures if tensions persisted. It also enacted nontariff countermeasures, most notably by letting provincial liquor authorities remove U.S. beer, wine and spirits from store shelves. These tools, which fall within Canada’s system of shared federal and provincial powers, sharply restricted market access for American producers.

Immediately after Trump’s announcement, eight of Canada’s 10 provinces imposed partial or full bans on U.S. alcohol imports by instructing their liquor boards to stop importing and selling U.S. alcohol altogether. In many cases, American products were physically removed from store shelves and online platforms – sometimes with instructions to target imports from U.S. “red” states that had supported Trump.

U.S. wine exports were hit hardest, plunging from $460 million to just $103 million, while distilled spirits fell from $238 million to $89 million and beer exports from $47 million to $17 million. Collectively, these declines slashed total U.S. alcohol exports to Canada from $744 million to $208 million, wiping out $536 million in trade.

The spat quickly became testy. The alcohol boycott is one of the reasons Trump and White House officials have called Canada “mean and nasty to deal with,” in the words of U.S. Ambassador to Canada Pete Hoekstra.

The trade war’s latest turn

Those provincial restrictions remained in place even after the two countries reached a partial deal exempting about half of USMCA‑compliant goods from ongoing tariffs in summer 2025, leading Canada to scale back some retaliatory levies. However, the de facto trade bans on U.S. alcohol remain in place.

Alcohol resurfaced again recently as a flash point, when the top U.S. trade official, Jamieson Greer, said in April 2026 that existing U.S. levies on Canadian industrial goods would stay in place and might even be toughened until Canada walked back its alcohol restrictions. That threat a drew sharp retort from Canadian Prime Minister Mark Carney.

Meanwhile, the trade dispute hasn’t prompted Canadians to drink less alcohol overall. Instead, their consumption has largely shifted to other countries, especially for wine. United Nations trade data shows that in 2024, American wine accounted for 21% of all imported wine in Canada before dropping to only 5% in 2025. That year, imports from major wine exporting countries not only increased but roughly offset the decline in imports from the U.S. For distilled spirits, the U.S. slipped from 24% in 2024 to only 10% in 2025, while beer has dropped from 13% to 5%. At the same time, Canadian imports of beer, wine, and spirits from other countries increased by 9%, 15%, and 7%, respectively.

“What’s different this time is that people aren’t just swapping one bottle, they’re rethinking the whole bar,” said Craig Peters, CEO of Canada’s Barnburner Whiskey, in an interview with the online magazine VinePair. “Traditionally, those rail spots were locked up by big U.S. brands for decades. Now, we’re seeing bars, especially independents, completely reset and go Canadian across the board.”

Dogs display many traits of great leaders − here are 5 breeds that can be your leadership role models

Source: The Conversation – USA (2) – By Aditya Simha, Professor of Management, University of Wisconsin-Whitewater

Watching how dogs approach life can provide lessons for leaders. meaghanbrowning/RooM via Getty Images

I have been a dog lover ever since I was a kid and have spent years learning about the temperaments and histories of different dog breeds, as well as famous dogs and their adventures. I have attended a variety of dog shows to meet various breeds and talk with their owners, and I’ve also lived with several dogs – including a dachshund, otterhound, German shepherd, Indian spitz and Labrador retriever – over the course of my life.

Beyond my canine concerns, I’m a professor of management who loves teaching courses and conducting research on leadership. So, it was a no-brainer for me to combine my two interests to write a book, “Learning Leadership from Dogs.” Various dog breeds embody distinct traits and behaviors that we humans can emulate to become better leaders.

Here are five qualities dogs model that any leader, at work or in life, can learn from.

Joie de vivre

Happy-go-lucky hounds have an abundance of joie de vivre, a French phrase that refers to a cheerful and exuberant enjoyment of life. My own otterhound, Fiona, amply embodied this trait. A simple walk in the woods or hike on the beach was all she ever wanted.

This kind of optimism and cheerfulness can make leaders more empathetic and pleasant to work with, partly because psychology research finds that positive moods increase helping, generosity and interpersonal understanding. Those are key ingredients of empathy.

Followers feel and perform better when led by good-natured, enthusiastic leaders who look on the bright side. A leader’s joie de vivre can be passed on to the team. Scholars of positive leadership call this process emotional contagion – how a mood or emotional tone can spread through a group.

Courage

Who wants to follow a timid leader, right? Most people want a leader who is brave and who walks the talk – someone who’s courageous enough to do the right thing under all circumstances, not just when it’s convenient to do so.

While there are many dog breeds that embody courage, I want to single out the Dutch shepherd. Smaller than the German shepherd and the Belgian Malinois, the Dutch shepherd is used in police and military work because of its athleticism, trainability and strong work ethic. Just like how Dutch shepherds run toward danger to protect others, courageous leaders take risks for their values and to support their team.

Intelligence

Leaders must not only know about their domain, they also need to be able to understand which of their followers needs to be treated or led differently. Both emotional and cognitive intelligence are essential for effective leadership and have positive consequences for their followers’ attitudes and performance.

I point to the border collie as a dog that exemplifies both forms of intelligence. The border collie not only knows how to herd sheep, but also which sheep to herd with patience and which sheep need a bit more sharpness.

This intelligence is something that needs to be guided and channeled. Border collies left without enough work or stimulation are famous for finding their own “jobs,” such as herding the human children, chasing shadows or inventing new mischief around the house.

Without proper direction, even brilliance can become counterproductive – another lesson leaders can keep in mind when managing their own flocks.

Kindness

Kindness is one quality that is sadly not given the amount of attention it merits in the world of management, even though it can shape whether followers feel respected, trusted and willing to contribute.

Displaying kindness is a canine specialty. The dog breed that comes to mind for me here is the Newfoundland. First bred in Canada and known as a fine water rescue dog, these gentle giants are supremely kind to everyone and display a benevolent, protective nature.

Leaders similarly need to be kind to their followers, even if a team member has failed at a task. A kind response does not mean ignoring mistakes; it means correcting them in a way that preserves dignity, making followers more likely to learn, speak up and try again. Together those patterns facilitate work environments that promote what researchers call psychological safety: a shared belief that people can ask questions, admit mistakes and raise concerns without fear of embarrassment, rejection or punishment.

Resilience

Resilience is not just toughness; it is the ability to recover from setbacks, adapt under pressure and keep moving forward when things don’t go as planned. Leaders rely on it during crises, failed projects, public criticism or periods of organizational change, all moments when uncertainty is high and confidence can falter.

Any leader can look to the Rhodesian ridgeback as a resilience role model. This breed hails from South Africa and was originally used to assist in lion hunting – an activity fraught with peril and with high prospects of failure. Rhodesian ridgebacks are dauntless dogs, always ready to try another dangerous hunt even in the wake of repeated failures.

Like these dogs, leaders often must confront perilous tasks with a high likelihood of failure, and they must be ready to bounce forward so they can eventually seize success. Without resilience, leaders may panic, withdraw or become overly reactive, especially during a crisis. When that happens, uncertainty spreads, confidence erodes and teams are less likely to stay focused or move forward effectively.

Dogs are the most popular choice of pet in the United States and worldwide. You probably don’t need to look far to find some furry friends who can inspire you with their admirable characteristics. Dogs may never author a leadership book, but they live out leadership lessons in courage, kindness and joy every day.
