Les toilettes peuvent rendre les routes africaines plus sûres, selon cette nouvelle étude

Voyager sur les routes africaines comporte de nombreux défis. La principale difficulté consiste à arriver à destination en toute sécurité. Le continent est l’une des régions du monde les plus touchées par des accidents de la route. Le nombre de morts de l’Afrique sur les routes représente un quart des victimes dans le monde, alors que le continent compte moins de 4 % du parc automobile mondial.

La situation en Afrique subsaharienne est particulièrement grave. Les accidents de la route touchent cette région plus que toute autre au monde. Son taux de mortalité routière de 27 pour 100 000 habitants est trois fois plus élevé que la moyenne européenne de 9 et bien supérieur à la moyenne mondiale de 18.

Il y a ensuite le problème des infrastructures routières en Afrique. Malgré la récente augmentation des investissements dans le développement routier, la qualité des routes dans de nombreux pays africains est généralement médiocre. Ce constat a été confirmé par des recherches, des enquêtes du Forum économique mondial et le classement international de la qualité des routes du Fonds monétaire international.

Les accidents et les mauvaises routes ne sont pas les seuls éléments qui peuvent rendre les déplacements moins agréables. Le manque de toilettes en est un autre. Lorsque l’envie de faire ses besoins presse, on se retrouve dans une situation compliquée. Les autorités prévoient rarement des toilettes adéquates, sûres et propres pour les voyageurs.

En 2020, un avocat qui défend l’intérêt public, Adrian Kamotho Njenga, a poursuivi en justice avec succès certaines autorités au Kenya. Il les a obligées à mettre des toilettes à la disposition des voyageurs.

Ce problème n’est pas propre à l’Afrique. Des défis similaires existent aux États-Unis et au Royaume-Uni.

La différence est que dans ces pays, des chercheurs étudient la question et produisent des connaissances pour sensibiliser et faire évoluer les choses.

Je suis chercheur senior en gouvernance de la mobilité à l’Unité d’études sur les transports de l’université d’Oxford. Mes recherches portent notamment sur l’accès aux toilettes dans les systèmes de mobilité. Dans un article récent, j’ai attiré l’attention sur les avantages des toilettes en matière de sécurité routière.

Je soutiens que l’amélioration de l’accès convenable des conducteurs aux toilettes peut avoir des avantages en matière de sécurité routière comparables à ceux de l’application des lois contre la conduite en état d’ivresse ou la fatigue au volant.

J’ai effectué des recherches dans des bases de données universitaires telles que Scopus et examiné plusieurs articles. J’ai constaté que l’amélioration de l’accès aux toilettes pour les conducteurs était rarement étudiée en tant que stratégie de sécurité routière en Afrique. Or, elle peut renforcer la sécurité routière en réduisant la distraction des conducteurs et d’autres pratiques de conduite dangereuses qui conduisent à des accidents de la route.

Les pertes liées aux accidents de la route en Afrique sont immenses. Il n’y a pas si longtemps, l’Union africaine déplorait qu’elles représentent environ 2 % du PIB annuel de ses États membres. Pour y remédier, il faudra une approche intégrant des solutions diverses, y compris des mesures innovantes, telles que faciliter l’accès aux toilettes pour les conducteurs sur la route.

Les avantages des toilettes pour la sécurité routière

Conduire alors que l’on a envie d’aller aux toilettes peut être une expérience éprouvante et une source importante de distraction. Cela peut rendre les conducteurs dangereux pour eux-mêmes et les autres usagers en détournant leur attention de la route et des conditions de circulation. Une urgence de se soulager peut affecter leur jugement et leur capacité à réagir face à des situations dangereuses.

La distraction et l’urgence peuvent rendre le conducteur impatient et l’inciter à rouler trop vite, à suivre de trop près les véhicules devant lui ou à tenter des manœuvres imprudentes pour se rendre à l’endroit le plus proche où il pourra se soulager.

Des recherches ont montré que les personnes qui ne peuvent pas uriner lorsque leur vessie est pleine souffrent d’une altération cognitive ou d’une baisse de concentration équivalente à celle d’une personne restée éveillée pendant 24 heures.

La détérioration cognitive associée à l’envie extrême d’uriner équivaut également à un taux d’alcoolémie de 0,05 %. Cela équivaut ou dépasse les limites de taux d’alcoolémie imposées aux conducteurs en Tunisie (0,05 %), au Soudan et en Mauritanie (0 %), au Maroc (0,02 %), au Mali (0,03 %), à Madagascar (0,04 %) et d’autres pays africains.

Tout cela suggère que conduire en ayant envie d’aller aux toilettes est aussi dangereux que conduire en état d’ivresse ou en état de fatigue. Cela implique également que l’amélioration de l’accès aux toilettes peut avoir des effets bénéfiques sur la sécurité routière comparables à ceux de l’application des lois contre la conduite en état d’ivresse ou en état de fatigue.

Les toilettes devraient être intégrées dans les projets d’aménagement routier et les systèmes de mobilité.

Il est temps d’investir dans l’accès aux toilettes dans les systèmes de mobilité

Pour commencer, les gouvernements du continent peuvent construire davantage de toilettes publiques. L’Afrique est l’une des régions les plus touchées par le manque de toilettes dans le monde. Selon l’Organisation mondiale de la santé, quelque 779 millions de personnes sur le continent n’ont pas accès de manière convenable à des toilettes adéquates, sûres et propres. La construction de toilettes publiques supplémentaires peut contribuer à lutter contre la pénurie générale de toilettes sur le continent, ainsi que dans le contexte de la mobilité.

Il est réjouissant de constater qu’au Ghana, par exemple, des promoteurs privés investissent dans des aires de repos le long des autoroutes. Ces infrastructures sociales de transport routier permettent aux voyageurs de se détendre, d’accéder à des biens et services et de socialiser pendant leur pause. Elles sont souvent équipées de toilettes payantes. Les gouvernements peuvent explorer des moyens de soutenir ces initiatives privées afin qu’elles se développent et deviennent plus abordables.

Cependant, les aires de repos sont souvent situées en périphérie. La plupart des conducteurs et autres usagers de la route circulent en ville. Lorsqu’ils ont besoin d’aller aux toilettes pendant leurs déplacements, certains conducteurs et autres voyageurs en milieu urbain sont susceptibles d’utiliser les toilettes disponibles dans les stations-service, les hôtels, les restaurants, les banques, les cafés, les salons de coiffure et autres établissements situés en ville.

On ne sait pas grand-chose sur leur coût, leur sécurité, leur propreté et leur emplacement, ni sur la gêne que peuvent ressentir ceux qui les utilisent. Les chercheurs devront étudier ces questions et partager leurs conclusions avec le public.

Lorsque davantage de personnes seront sensibilisées à ces questions, il pourrait y avoir un changement de mentalité pour exiger et soutenir un meilleur accès aux toilettes dans le cadre de la politique de mobilité.

Pourquoi en France les start-ups dirigées par des femmes lèvent en moyenne 2,5 fois moins de fonds que celles dirigées par des hommes ?

Le financement d’une entreprise n’est pas qu’une affaire d’argent. C’est une relation, une danse à deux où chaque partenaire projette des stéréotypes. Une étude donne la parole à des entrepreneures qui portent elles-mêmes ces représentations.


En France, les start-ups fondées par des femmes lèvent en moyenne 2,5 fois moins de fonds que celles fondées par des hommes. Ce constat illustre à quel point le financement reste l’un des principaux enjeux liés de l’entrepreneuriat féminin, parfois décrit comme un second plafond de verre. Il faut déjà s’imposer comme entrepreneuse, puis encore franchir la barrière de l’accès aux capitaux.

Jusqu’ici, c’est l’offre de financement qui a été principalement étudié : combien d’argent est disponible, comment fonctionnent les banques et les fonds ? Mais pour obtenir un financement, il faut d’abord… en faire la demande. Sur ce point, la recherche est encore rare.

C’est précisément ce que nous avons exploré dans notre étude publiée dans la Revue internationale PME, à travers 29 entretiens narratifs avec des entrepreneures. Leurs récits montrent que la demande de financement est avant tout une relation : une danse à deux entre entrepreneuse et financeurs, imprégnée d’attentes, de craintes et de stéréotypes.

La finance pensée comme un univers masculin

Dans cette danse, l’investisseur est spontanément imaginé comme un homme : « Quand je pense à un investisseur, je pense automatiquement à un homme » raconte une entrepreneure. Cela leur confère une légitimité « naturelle », rationnels, ambitieux, cartésiens.

Certaines entrepreneures y voient même un atout : « Je pense que les hommes investisseurs seraient plus à même de nous pousser dans nos retranchements pour faire avancer notre projet », estime l’une. Mais cette admiration s’accompagne souvent d’un malaise.

Plusieurs redoutent un regard condescendant ou un manque de crédibilité : « Si je demande un financement à un homme, j’aurais tendance à penser qu’il estime que j’ai moins de revenus », observe une autre. D’autres évoquent un sentiment de domination, voire le risque d’abus : « Je ne suis pas une friandise. Avec une femme au moins, on ne risque pas d’attouchement », insiste une fondatrice.

Les investisseuses, trop bienveillantes ?

Quand la partenaire de danse est une investisseuse, le pas change. Elle est souvent perçue comme plus accessible et plus à l’écoute « Je pense que les femmes seraient plus bienveillantes avec moi » estime une entrepreneure. Pour certaines, elles incarnent même un modèle inspirant.

On pourrait croire que les entrepreneures se tournent plus facilement vers des investisseuses. Mais la réalité est plus ambivalente. Certaines redoutent un excès de bienveillance, perçu comme un manque d’exigence :

« C’est très cliché, mais j’aurais peur qu’avec un trop-plein de bienveillance, on ne me “pousse” pas assez. J’ai l’impression qu’entre hommes, on fait plus d’argent, on pousse plus ».

D’autres craignent au contraire une rivalité ou un jugement plus sévère : « On a un peu plus de pression face à une femme, car c’est soit de la compassion, soit du mépris… » explique une autre.

« Pas prévu de faire des enfants ensemble »

Face à ces représentations contrastées, les entrepreneures apprennent à choisir leurs partenaires de danse.

Certaines privilégient les investisseuses pour des projets destinés à un public féminin, ou dans des situations particulières comme une grossesse perçue comme mieux acceptée par une femme. D’autres préfèrent des investisseurs masculins, jugés plus crédibles ou plus susceptibles de « pousser » leur projet.

Pour la première fois, une étude révèle ce qui se passe dans le cerveau d’un entrepreneur


Notons que toutes ne se laissent pas enfermer dans ce jeu de projections :

« Pour mon financement, je cherche des investisseurs qui font écho à mes valeurs profondes. Fille ou garçon, nous n’avons pas prévu de faire des enfants ensemble donc ce n’est pas un problème » raconte une fondatrice.

Une danse à deux traversée de stéréotypes

Ces témoignages rappellent que le financement entrepreneurial n’est pas qu’une affaire de capitaux ou de business plans. C’est une relation, une danse à deux, où chaque partenaire projette des stéréotypes.

Nos résultats montrent que les entrepreneures elles-mêmes portent et mobilisent des représentations. Voir les hommes comme plus rationnels, ou les femmes comme plus bienveillantes, influe sur la façon dont elles valorisent une relation de financement, et parfois sur leur capacité à s’y engager.

Améliorer l’accès au financement ne peut pas se limiter à féminiser les instances d’investissement. Il faut aussi comprendre comment ces imaginaires se construisent et orientent les relations. Car finalement, lever des fonds, ce n’est pas seulement obtenir un chèque. C’est accepter de danser, et la danse n’a de sens que si les deux partenaires trouvent l’accord.

Pentagon investigation of Sen. Mark Kelly revives Cold War persecution of Americans with supposedly disloyal views

In an unprecedented step, the Department of Defense announced online on Nov. 24, 2025, that it was reviewing statements by U.S. Sen. Mark Kelly, a Democrat, who is a retired Navy captain, decorated combat veteran and former NASA astronaut.

Kelly and five other members of Congress with military or intelligence backgrounds told members of the armed forces “You can refuse illegal orders” in a video released on Nov. 18, reiterating oaths that members of the military and the intelligence community swear to uphold and defend the Constitution. The legislators said they acted in response to concerns expressed by troops currently serving on active duty.

President Donald Trump called the video “seditious behavior, punishable by death.”

Retired senior officers like Kelly can be recalled to duty at any time, which would make it possible for the Pentagon to put Kelly on trial under the Uniform Code of Military Justice, although the Defense Department announcement did not specify possible charges. Defense Secretary Pete Hegseth wrote online that “Kelly’s conduct brings discredit upon the armed forces and will be addressed appropriately.”

This threat to punish Kelly is just the latest move by the Trump administration against perceived enemies at home. By branding critics and opponents as disloyal, traitorous or worse, Trump and his supporters are resurrecting a playbook that hearkens back to Sen. Joseph McCarthy’s crusade against people he portrayed as domestic threats to the U.S. in the 1950s.

As a historian who studies national security and the Cold War era, I know that McCarthyism wrought devastating social and cultural harm across our nation. In my view, repeating what I believe constitutes social and political fratricide could be just as harmful today, perhaps even more so.

Targeting homegrown enemies

In the late 1940s and early 1950s, many Americans believed the United States was a nation under siege. Despite their victory in World War II, Americans saw a dangerous world confronting them.

The communist-run Soviet Union held Eastern Europe in an iron grip. In 1949, Mao Zedong’s communist troops triumphed in the bloody Chinese civil war. One year later, the Korean peninsula descended into full-scale conflict, raising the prospect of World War III – a frightening possibility in the atomic era.

Anti-communist zealots in the U.S., most notably Wisconsin Republican Sen. McCarthy, argued that treasonous Americans were weakening the nation at home. During a February 1950 speech in Wheeling, West Virginia, McCarthy asserted that “the traitorous actions of those who have been treated so well by this nation” were undermining the United States during its “final, all-out battle” against communism.

When communist forces toppled China’s government, critics such as political activist Freda Utley lambasted President Harry Truman’s administration for what they cast as its timidity, blundering and, worse, “treason in high places.” Conflating foreign and domestic threats, McCarthy claimed without evidence that homegrown enemies “within our borders have been more responsible for the success of communism abroad than Soviet Russia.”

From 1950 through 1954, Sen. Joseph McCarthy, a Wisconsin Republican, used his role as chair of two powerful Senate committees to identify and accuse people he thought were Communist sympathizers. Many of those accused lost their jobs even when there was little or no evidence to support the accusations.

As ostensible proof, the senator pointed to American lives being lost in Korea and argued that it was possible to “fully fight a war abroad and at the same time … dispose of the traitorous filth and the Red vermin which have accumulated at home.”

Political opponents might disparage McCarthy for his “dishonest and cowardly use of fractional fact and innuendo,” but the Wisconsinite knew how to play to the press. Time and again, McCarthy would bombastically lash out against his critics as he did with columnist Drew Pearson, calling him “an unprincipled liar,” “a fake” and the owner of a “twisted perverted mentality.”

While McCarthy focused on allegedly disloyal government officials and media journalists, other self-pronounced protectors of the nation sought to warn naive members of the public. Defense Department pamphlets like “Know Your Communist Enemy” alerted Americans against being duped by Communist Party members skilled in deception and manipulation.

Virulent anti-communists denounced what they viewed as inherent weaknesses of postwar American society, with a clearly political bent. Republicans asserted that cowardly, effeminate liberals were weakening the nation’s defense by minimizing threats both home and abroad.

Censure and worse

In such an anxiety-ridden environment, “red-baiting” – discrediting political opponents by linking them to communism – spread across the country, leaving a trail of wrecked lives. From teachers to public officials, anyone deemed un-American by McCarthyites faced public censure, loss of employment or even imprisonment.

Under the 1940 Smith Act, which criminalized promoting the overthrow of the U.S. government, hundreds of Americans were prosecuted during the Cold War simply for having been members of the Communist Party of the United States. The act also authorized the “deportation of aliens,” reflecting fears that communist ideas had seeped into nearly all facets of American society.

The 1950 Internal Security Act, widely known as the McCarran Act, further emphasized existential threats from within. “Disloyal aliens,” a term the law left purposefully vague, could have their citizenship revoked. Communist Party members were required to register with the government, a step that made them susceptible to prosecution under the Smith Act.

Immigrants could be detained or deported if the president declared an “internal security emergency.” Advocates called this policy “preventive detention,” while critics derided the act as a “Concentration Camp Law,” in the words of historian Masumi Izumi.

Scapegoating outsiders

The scaremongering wasn’t just about people’s political views: Vulnerable groups, such as gay people, were also targeted. McCarthy warned of links between “communists and queers,” asserting that “sexual perverts” had infested the U.S. government, especially the State Department, and posed “dangerous security risks.” Closeted gay or lesbian employees, the argument went, were vulnerable to blackmail by foreign governments.

Fearmongering also took on a decidedly racist tone. South Carolina Governor George Bell Timmerman, Jr., for instance, argued in 1957 that enforcing “Negro voting rights” would promote the “cause of communism.”

Three years later, a comic book titled “The Red Iceberg” insinuated that communists were exploiting the “tragic plight” of Black families and that the NAACP, a leading U.S. civil rights advocacy group, had been infiltrated by the Kremlin. Conservatives like Arizona Sen. Barry Goldwater criticized the growing practice of using federal power to enforce civil rights, calling it communist-style social engineering.

In an interview on Oct. 13, 2024, then-candidate Donald Trump described Democratic Party rivals as ‘the enemy from within’ and suggested using the armed forces against ‘radical left lunatics’ on Election Day.

A new McCarthyism

While it’s never simple to draw neat historical parallels from past eras to the present, it appears McCarthy-like actions are recurring widely today. During the Red Scare, the focus was on alleged communists. Today, the focus is on straightforward dissent. Critics, both past and present, of President Donald Trump’s actions and policies are being targeted.

At the national level, Trump has called for using military force against “the enemy from within.” On Sept. 30, 2025, Trump told hundreds of generals and admirals who had been called to Quantico, Virginia, from posts around the world that the National Guard should view America’s “dangerous cities as training grounds.”

The Trump administration is making expansive use of the McCarran Act to crack down on immigrants in U.S. cities. White House adviser Stephen Miller has proposed suspending the constitutionally protected writ of habeas corpus, which entitles prisoners to challenge their detentions in court, in order to deport “illegal aliens,” alleging that the U.S. is “under invasion.”

In my home state of Texas, political fearmongering has taken on an equally McCarthyesque tone, with the Legislature directing the State Board of Education to adopt mandatory instruction on “atrocities attributable to communist regimes.”

Perhaps it is unsurprising, then, that right-wing activist Laura Loomer has unapologetically called for “making McCarthy great again.”

Disagreement is democratic

The history of McCarthyism shows where this kind of action can lead. Charging political opponents with treason and calling the media an “enemy of the people,” all without evidence, undercuts democratic principles.

These actions cast certain groups as different and dehumanize them. Portraying political rivals as existential threats, simply for disagreeing with their fellow citizens or political leaders, promotes forced consensus. This diminishes debate and can lead to bad policies.

Americans live in an insecure world today, but as I see it, demonizing enemies won’t make the United States a safer place. Instead, it only will lead to the kind of harm that was brought to pass by the very worst tendencies of McCarthyism.

A database could help revive the Arapaho language before its last speakers are gone

Source: The Conversation – USA – By Andrew Cowell, Professor of Linguistics, University of Colorado Boulder

There are fewer than 100 speakers of the Arapaho language today. Mark Makela/GettyImages

I was hired at the University of Colorado Boulder in 1995 as a language professor. I relocated from Hawaii, where I had learned the Hawaiian language.

When I arrived in Colorado, I decided I needed to learn about the Indigenous language of the Boulder and Denver area, Arapaho. The Arapaho people had occupied the area for many years until they were forced to leave in the 1860s.

I first visited the Northern Arapaho people on the Wind River Reservation in Wyoming in 1999. At that time, there were hundreds of speakers of the Arapaho language.

Today, there are less than 100, and all are over the age of 70.

The Arapaho people in Wyoming and Colorado believe their language can still survive, and so do I. That’s why I am working to combine decades of language documentation with new technological approaches in order to help revive the language.

Loss of Native languages

Many Native American languages currently have few Native speakers, and the speakers are typically the oldest members of the community. The languages of the Wichita and Kansa people, for example, are among many that are no longer spoken at all.

Native American languages have been in decline in the face of Euro-American pressure for centuries.

On the Great Plains, this decline accelerated after World War II when Native soldiers came home after seeing prosperity off the reservation.

Arapaho elders tell me that bilingual parents decided to speak only English to their children to improve their chances of success in life. They were certain the tribal languages would come “later.”

But “later” didn’t happen. Boarding schools had already been suppressing the language, and now economic improvements brought cars, radios and televisions to Wind River, further promoting the use of English. Without language exposure in the home, children were not able to acquire good speaking abilities.

A documentary from Rocky Mountain PBS about Native American people who lost their language as children.

Today, however, tribal communities around the country increasingly want to maintain or reacquire their languages. Efforts to do this have been going on for several decades, with some successes, such as the Mohawk language of New York and Canada, Cherokee in Oklahoma and North Carolina and the Blackfoot language of northern Montana.

In most places however, numbers of Native speakers continue to decline, while learning among younger speakers progresses slowly.

Uses of data for curriculum

My early work focused on documenting the Arapaho language. Past linguists working with Native languages typically focused on traditional storytelling, as well as audio-recorded data. But my interest in anthropology led me to focus on conversation and everyday interaction. I also recorded on video to capture social settings, gestures and sign language. And to better understand the role of the language in daily use, I worked to become a good speaker myself.

I have compiled my documentation into a database that contains over 100,000 sentences of natural Arapaho speech. All of this has been transcribed, translated into English and accompanied by detailed linguistic analysis.

The database is further supported by an online learning site and an online dictionary of around 25,000 entries. They are among the largest such resources for an Indigenous language, though resources do exist for other languages, such as Yurok.

From documentation to curriculum

In response to the Arapaho people’s goal of language revitalization, my own work has shifted from documentation to assisting teachers, students and curriculum developers. The database turns out to have great value in this area.

Adult learners can watch the videos along with the Arapaho transcriptions or English translations, or both, and review the detailed grammatical analysis.

However, it is quite difficult for young learners to immediately benefit from listening to natural discourse. That’s why carefully graded curricula are crucial. Unlike for commonly taught languages such as French or Spanish, materials for most Native American languages are just being developed.

Arapaho can be challenging to learn because its structure is quite different from English. Many small chunks of meaning are combined to produce long, complex words. For example, an English speaker can start with “happy” and produce “un-happi-ness.” Arapaho speakers typically add three, four or even five prefixes, and multiple suffixes as well. A speaker can say the word “niibeetwonwoteekoohunoo” – which has six separate meaningful chunks. This translates to English, “I want to go and drive to town.”

There is little value in memorizing such complex words, just as English learners don’t memorize entire sentences. Instead, Arapaho learners need to understand the separate parts, and how they combine.

Previous efforts have succeeded in teaching children to speak basic Arapaho. The challenge now is to keep improving their Arapaho language abilities, using a graded curriculum that continues through all school levels.

The database can identify and label the individual chunks of words, and assign meanings to each chunk. A beginner’s dictionary of 1,300 entries has been created by calculating the overall frequency of base words in the 100,000 sentences, and then selecting only the most common ones.

The list has been broken down further to produce target vocabulary for each grade level. Smaller chunks of prefixes and suffixes are also measured, and sequential grammar-learning goals can be produced based on frequency and complexity.

A draft Arapaho learning sequence has been created, with 44 stages. It is now possible for the first time to produce a full, progressive language curriculum for Arapaho. The next step is to develop more curricular materials and train teachers to use them.

The sequence of 44 stages is now being introduced at Wyoming Indian Elementary School, the first school on the Wind River Reservation to pioneer dual-language classrooms.

Limitations of technology

Technology is not a magic bullet, however. Only Native people can save their languages, by choosing to learn and speak them.

Because artificial intelligence works using large language models, it needs billions of words of discourse to be trained effectively in a language. No Indigenous language has nearly that amount of data, so the capacity of AI to address Native language endangerment is limited. Moreover, many Indigenous communities are wary of AI due to concerns over data sovereignty and cultural property rights.

My own old-fashioned experience as a learner and teacher has proved crucial. I can see where difficulties lie for learners, and how to fine-tune computational measurements and predictions. I’ve learned that success in helping revitalize Native languages depends on researchers building long-term relationships with Native peoples and, ideally, speaking Native languages. Only then can new technologies be applied most productively.

How food assistance programs can feed families and nourish their dignity

Source: The Conversation – USA (3) – By Joslyn Brenton, Assistant Professor of Sociology, Ithaca College

The 2025 government shutdown drew widespread attention to how many Americans struggle to get enough food. For 43 days, the more than 42 million Americans who receive Supplemental Nutrition Assistance Program benefits had to find other ways to stock their cupboards.

When asked how she felt about her benefits being suspended, one woman in West Virginia told a New York Times reporter, “We’re angry. Because we do count!”

Her sentiment reflects an often underappreciated fact about food. Food is not just a matter of survival. What and how you eat is also a symbol of your social status. Being unable to reliably feed your family healthy and nutritious foods in a way that aligns with your values can feel undignified. It can make people feel unseen and less important than others.

As researchers who study food inequality, nutrition and food justice, we have spent decades surveying and interviewing Americans about how they eat. We have witnessed firsthand how food assistance does help people meet their basic needs, but how it can also be stigmatizing and diminish their sense of dignity.

We have also studied alternatives to typical charitable food programs that, despite good intentions, tend to induce shame. We have learned that it is possible to help people put food on the table while preserving their dignity.

Dignity and food assistance

Addressing the root causes of food insecurity – what happens when people lack steady access to the food they need for a nutritious diet that’s in keeping with their preferences – is a persistent problem in the United States.

Thus, the demand for SNAP benefits, which help Americans buy groceries, other government nutrition programs, and food banks and food pantries rarely declines much – even when the economy is strong. Yet relying on food assistance programs does not tend to support a healthy diet and can take a toll on mental health.

As interviewers and clinicians, we have heard mothers describe the shame they feel when SNAP benefits do not cover the entire grocery bill. We have witnessed the frustration that comes with walking down a food pantry aisle lined with signs instructing hungry people to “take only 1 item!”

“The stuff looks like almost trash, but they give it to you,” one woman we interviewed said of her experience with food pantries and the like.

These kinds of stories are not uncommon. Charitable food programs receive leftover items from grocery stores, donations from community food drives and local businesses, and sometimes surplus from local farms. Food is often damaged in transport or from being handled too many times. A review of the research found that many people who use food pantries described the food as unhealthy, moldy or inedible. Being given unhealthy and unappealing food in a time of need is a double burden.

While free food may fill the stomach, it does not satisfy the desire to feel fully human and worthy of nourishment.

People who visit food banks have told researchers that they have come to expect low-quality food and few choices. When food aid is provided that way, it can leave the people it is supposed to help feeling powerless and ashamed.

These indignities are compounded by the fact that people who visit food banks and food pantries routinely face suspicion and surveillance around what they buy and how they eat, intensifying the stress associated with food insecurity.

In our research, we saw cashiers hovering over mothers using SNAP EBT cards in the self-checkout line. Politicians routinely suggest that SNAP is corrupt, contributing to nationwide perceptions that people who rely on this program are unfairly gaming the system. One study found that more than two-thirds of the Americans people who get food assistance have been the target of hostile comments and interactions from strangers at the grocery store.

Minimizing stigma

Several studies have shown that food programs do not need to sacrifice dignity to offer help. Programs that offer opportunities for people with lower incomes to receive and give back are important.

In Canada, bulk-buying food cooperatives did just that. Food assistance programs confer dignity when they make people feel good. People seeking help feel more satisfied after visiting food pantries that keep convenient hours or offer fresh produce.

SNAP has also tried to promote client dignity by ensuring that benefits are accepted in major grocery stores and distributing the funds to debit cards, allowing people to look and feel like everyday shoppers.

Yet despite these efforts social stigma persists. People who are enrolled in the SNAP program are still routinely devalued and judged for being poor in a society that assigns social value and worth based on one’s position on the economic ladder.

Cultivating dignity in food assistance

Minimizing stigma improves food assistance. Intentionally cultivating food dignity may be the next step.

Our assessment of a nationwide meal kit program demonstrated how dignity can be cultivated when food assistance programs consider the nutritional, emotional, aesthetic and cultural dimensions of food and eating.

In 2021, we conducted 116 interviews with participants of a meal kit program called Pass the Love. The program was free and anyone could enroll, no questions asked. The meal kits contained the necessary food and recipes to make three vegetarian meals a week, such as sesame coconut noodle salad or carrot coconut dal with rice. The program ran for four consecutive weeks.

When we interviewed participants about their experiences during and after the program, we learned that while they were thankful for the free food, what mattered more was the high quality, how it was packaged and how it conveyed care and respect.

Most participants had incomes at or well below the poverty line. They described what we came to call a “high dignity food experience,” meaning that it generated positive feelings and a sense of worth.

Opening the nicely packaged meal kit boxes each week felt like “Christmas,” to some people and a “gift” to others. Many found the “thought and care” that went into the program remarkable. Offering high-quality food to make nutritious, complete meals symbolized that low-income or food-insecure people deserve to eat well and feel good.

Our research, like similar studies that others have conducted, shows that treating food as a basic human right requires more than just giving people something to eat. It means ensuring unconditional access to the culturally appropriate fresh and nutritious food people need to thrive not just physically, but psychologically and socially.

What makes a true Santa is inside – and comes with the red suit

When you picture Santa Claus, a white, bearded, overweight and jolly man who dashes around delivering gifts to children during the Christmas season probably comes to mind. Yet, not everyone who dons the red suit fits this stereotype.

That’s what Bethany Cockburn, Borbala Csillag and I learned when we teamed up to study professional Santas. For our study, we looked into how these professional Santas were able to “be” Santa, even if they didn’t fully fit the image.

As we explained in a forthcoming article in the Academy of Management Journal, many who do this work don’t see it as just a job – it’s a calling. For some professional Santas, it’s especially important that they look and feel like Santa to experience that sense of purpose in their work.

We surveyed 849 professional Santas who live across the U.S. and interviewed 53 of them, collecting data between 2018 and 2021. We identified three types of professional Santas: prototypical (64%), semi-prototypical (23%) and nonprototypical (13%).

Prototypical Santas look the part. They are white and overweight, have real beards and express confidence that they are the right fit.

Semi-prototypical Santas looked the part, too, but felt like they weren’t quite suitable for a range of reasons. They might be introverted or use a fake beard.

Nonprototypical Santas had characteristics at odds with the stereotype. They might be nonwhite, female or gay, or have a physical disability.

Whereas prototypical Santas could easily slide into the Santa role, the process was more complex for the others.

Semi-prototypical Santas did things like come up with stories they’d tell themselves or share with children to explain away their fake beards. Nonprototypical Santas had values aligned with the Santa image, such as being peaceful, loving and kind. But they still made a big effort to look like what people expect when they visit a Santa.

“Should it be a difference if you’re a Jewish Santa Claus or a Catholic Santa Claus?” asked an atheist professional Santa we called “Santa Aquila.” “No. You’re Santa Claus. What do you do? You’re not even supposed to preach anything.”

Another Santa whom we called “Santa Lynx” hid that she was female in part by flattening her chest.

Why it matters

While anyone can take a turn being their neighborhood potluck’s Santa, the one you meet at the mall probably attended some combination of Santa schools, webinars and training.

For instance, the Charles W. Howard Santa Claus School was founded in 1937 and conducts an annual Santa training each year. National networks also exist, such as the Fraternal Order of Real Bearded Santas, which says it has 1,000 members, – and the IBRBS, formerly known as the International Brotherhood of Real Bearded Santas, offering meetups and professional support.

There are also local organizations, such as the Lone Star Santas network in Texas.

Although most professional Santas are paid for their work, many do this voluntarily.

It’s not uncommon for there to be some sort of expectation around who should have a particular occupation. Pilots tend to be male, most schoolteachers are female, and salespeople are often seen as extroverted.

But that doesn’t mean that women can’t be pilots, men can’t be teachers or that introverts can’t work in sales.

What’s next

I’m now looking at how broader institutional environments, current events and social movements can shape how people experience their callings and find meaning at work.

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

Lions have two types of roar – new research

Source: The Conversation – UK – By Jonathan Growcott, PhD student in Environmental Intelligence, University of Exeter

The roar of an African lion is one of the most iconic sounds of the animal kingdom. However, my new research suggests it should actually be separated into two distinct vocalisations: the full-throated roar, and an “intermediary roar” with a flatter, less varied sound. Making this distinction could have important implications for lions’ conservation.

The total population of wild lions in Africa is estimated to be between 22,000 and 25,000, but this number is half what it was 25 years ago. The main drivers of this decline are habitat loss and fragmentation, reduction in prey, and conflict with local people. According to the International Union for Conservation of Nature red list, lions are now vulnerable to extinction.

My colleagues and I investigated roaring in lions to get better at distinguishing between their different vocalisations. But our findings may make it easier to monitor lions’ numbers, which in turn would make it easier to protect them.

You might think you know a lion’s roar from the clip used by MGM at the start of all its films – but that isn’t quite right. It’s actually a tiger’s roar dubbed on top of this famous piece of cinema. Compared with a lion, a tiger’s roar is often raspier and higher-pitched.

In fact, male and female lions produce what scientists call a “roaring bout”. Each begins with a series of soft moans, followed by a subsection of intermediary and full-throated roars, which finally subside into a repetition of grunts.

There is no set length of time a roaring bout will last (though most are between 30 and 45 seconds), and the number of vocalisations within each subsection does not keep to a strict formula.

The roaring bout is important behaviour. Not only does it signal to other lions in their pride where they are, but to unfriendly lions, bouts can be used to advertise territorial boundaries.

The loudest, most complex component of a lion’s roaring bout is the full-throated roar, which is an individually identifiable sound. Each lion’s full-throated roar is as specific to the individual as the pattern of spots are to a leopard (and as my 2024 paper found, their roar too).

Population density estimates are a key metric for identifying priority areas for conservation. If individual lions can be identified by their full-throated roars, then researchers could use this to count them.

However, picking out the full-throated roars from other vocalisations within a roaring bout is tricky. Even for those with expert ears, it is a subjective process which is prone to human bias.

The reason becomes clearer when you look at a spectrogram of a lion’s roaring bout – a visual representation of its sounds using an x-axis of time (seconds) and y-axis of frequency (hertz). The full-throated roar at the start of the mid-section of the bout rarely looks or sounds the same as the roar that occurs right before the grunts kick in. Which made me wonder: should these different roars be classified the same?

My colleagues and I leaned on AI to help us analyse our roar recordings. Perhaps this could help solve the issue of subjectivity, we thought, and classify lion vocalisations automatically, creating a tool so that other researchers always know which roar is right for counting lions.

We used supervised machine learning to classify the vocalisations which occur in a lion’s roaring bout into three call types: full-throated roars, grunts, and our newly identified intermediary roar.

From the spectrogram, we could see that the full-throated roar is loud, complex and arcs in pitch. The intermediary roar was a flatter sound with less variation – and it always followed the full-throated roars. Grunts were shorter and even more compact.

Using simple acoustic parameters – the duration of each vocalisation and its maximum frequency – we could then identify each call type with an accuracy of 95.4%. As the full-throated roars are unique to each individual lion, we wanted to test whether our AI analysis of full-throated roars was better at distinguishing between different lions than human hearing.

We found we could identify individual lions at an accuracy of 94.3% – an improvement of 2.2% over when human-selected full-throated roars were used. Using this technique for identifying full-throated roars could hopefully lead to more accurate population density estimates of lions.

It is exciting to discover the language of lions is more complex than previously thought. However, it is unclear what the communicative differences of the two roar types may be.

Scientists have long believed that lion roars may convey information relating to pride size, age and identity – but without Dr Doolittle to translate the meaning of moans, grunts and roars, this is still guesswork.

Therefore, it may take some time before “lion” appears as an option on Duolingo. For now, we should just celebrate the fact that AI can help us to discover more about wild phenomena as iconic as a lion’s roar.

Any peace deal in Ukraine must be just and fair – the plan proposed by the US and Russia was neither

Source: The Conversation – UK – By Selbi Durdiyeva, Visiting Scholar, Nottingham Law School, Nottingham Trent University

Details of a new peace plan for Ukraine are emerging after officials from the US, Ukraine and its European allies met in Geneva on November 23. They discussed the 28-point plan presented by Russia and the US the previous week, which has been widely criticised as requiring concessions from Kyiv that critics said would be tantamount to surrender.

These two plans, which represent the contrasting positions approved by Ukraine and Russia, are now being discussed in Abu Dhabi by officials from the US, Russia and Ukraine.

The plan which emerged from Geneva is reportedly based on a European counter-proposal to the US-Russia plan that had been developed in Miami by US envoy Steve Witkoff and Kirill Dmitriev, head of Russia’s sovereign wealth fund.

Full details of the Geneva plan have yet to be published. But reports suggest that unlike the US-Russian plan, it leaves open the door to Nato membership, removes restrictions on the size of Ukraine’s post-war army, and removes a proposal for an amnesty for war crimes committed since Russia’s invasion in February 2022.

The most contentious issues, including any territory to be ceded by Kyiv and Ukraine’s future Nato membership – something that Russia strongly opposes – will be decided by the Ukrainian president, Volodymyr Zelensky, and his US counterpart, Donald Trump. Ukraine is calling for a meeting between Trump and Zelensky within days to iron out the remaining issues.

It’s no surprise that neither Ukraine nor its allies in Europe were happy with the the US-Russia deal developed by Witkoff and Dmitriev. Apart from looking more like a plan for Kyiv’s capitulation than a credible pathway to peace, it presents some serious problems – both legal and moral.

Territorial concessions

The 28-point US-Russia proposal suggests Ukraine should concede parts of Ukraine’s internationally recognised territory including Crimea, Donetsk and Luhansk, which would then become internationally recognised as part of Russia. It also calls for the frontlines to be frozen in Kherson and Zaporizhzhia, with “de facto recognition” along the current line of contact between the two armies.

This would legitimise acquisition of territory by means of force and aggression, and hence would be in contravention of obligations under Article 2(4) of the UN Charter, which prohibits the “the threat or use of force against the territorial integrity or political independence of any state”.

The illegality of Russia’s invasion in 2022 was underlined in June 2025 when the Council of Europe established a special tribunal to prosecute senior political and military leadership “for the crime of aggression against Ukraine”.

If the territorial concessions detailed in the US-Russia plan were to be adopted, they would hinder effective investigation and prosecution of any such crimes of aggression – and thus set a dangerous precedent for future conflicts.

Impunity and accountability

The US-Russia plan’s proposed blanket amnesty for war crimes also contradicts international law. The law governing conduct of hostilities – and public international law in general – imposes an obligation for states to investigate, prosecute and punish war crimes.

While international law does not outlaw amnesties in pursuit of reconciliation, for the establishment of truth or to prevent war recurring, these should not interfere with a state’s obligation to investigate and prosecute international crimes. So, blanket amnesties are incompatible with this requirement.

The scale of documented violations in Ukraine over nearly four years makes the idea of an amnesty especially troubling. The Ukrainian authorities, with support from civil society, have documented more than 183,000 alleged war crimes since 2022.

The International Criminal Court has issued arrest warrants for senior Russian figures including Russia’s president, Vladimir Putin. National prosecutors in Europe are pursuing cases under universal jurisdiction.

Granting amnesty would nullify these investigations. It would signal that even the gravest crimes can go unpunished as a result of political deal-making.

The principles of transitional justice place victims at the centre of any post-conflict processes. They are entitled, under international law, to truth, justice and reparations. But the US-Russia plan does not outline any role for victims. Instead, it effectively deprives them of their right to pursue justice.

Research suggests that peace agreements without mechanisms to ensure accountability all too often end up with further outbreaks of violence. The pursuit of justice, which can include – but should not be limited to – criminal prosecutions, can be slow, costly and imperfect. But it tends to strengthen the rule of law and provide some form of remedy to the victims.

The US-Russia plan’s clause limiting the size of Ukraine’s post-conflict armed forces to 600,000 personnel is also controversial.

It is common to see measures such as demobilisation and disarmament in non-international armed conflicts. This was part of the settlement in peace negotiation processes for Colombia’s lengthy civil war in 2016. But applying them to a state which is the victim of aggression in an international armed conflict reverses the logic of accountability.

Ukraine is the state under attack. Limiting its defence capability while the aggressor retains its forces undermines both security and justice.

A fragile ‘peace’

Critics have described the US-Russia plan as “a gift to Putin”, as it aligns with the Kremlin’s longstanding demands while disregarding Ukraine’s legal rights. It would transform the future of millions of Ukrainians into a bargaining chip for great-power politics.

However, it appears that Kyiv’s European allies recognise this danger. The negotiations now underway in Abu Dhabi will be vital – as will any meeting between Trump and Zelensky to agree the framework of a new deal which fairly represents Kyiv’s position.

A genuine and just peace agreement must reflect the system of international law which, for 80 years, has sought to prevent the sort of aggression that Russia has unleashed on Ukraine. The 28-point plan presented by the US and Russia clearly failed to meet that test.

It is now up to Ukraine and its allies to ensure that any plan which does go forward rests on justice, accountability and the rights of victims – not on concessions to an aggressor.

Golden retriever and human behaviour may be linked by the same genes – new research

Source: The Conversation – UK – By Daniel Mills, Professor of Veterinary Behavioural Medicine, University of Lincoln

PeopleImages/Shutterstock

Humans have probably shared their homes with dogs ever since they first settled. So it could be argued that there is no such thing as “human society” without including animals as part of it. Our long shared history with dogs has even be described as a form of co-evolution.

And a new study my colleagues at Cambridge and I published shows golden retrievers and humans seem to share a genetic basis for at least some behaviour.

Dogs show many adaptations that might help them live and co-operate with people. Ancient humans may even have been selected dogs’ ancestors for an ability to eat a more human diet than wolves. At a psychological level there are many adaptations that aid communication between the two species, like an ability to follow human gestures such as pointing, that exceeds that of our closest relatives, chimpanzees.

Dogs also appear to be exceptionally skilled at responding appropriately to human emotion. But it is not all one sided. Humans seem to show an intuitive understanding of the nature of dogs’ vocalisations.

Nowadays, our relationship includes sharing the hustle and bustle that is so often a feature of modern living. So it is not surprising that there is an exceptionally high prevalence of stress-related problems arising in dogs, especially in countries like the US.

This has led researchers to question to what extent we might share mental health problems too. Recently there have been several claims about the potential for an autism-like syndrome in dogs. In March 2025, a similar genetic marker was identified for some of the social problems related to autism.

Our study has taken this genetic search to another level. My team and I analysed the genetic code and behaviour of 1,300 golden retrievers, looking for genes associated with their behavioural traits. “Equivalent” genes in humans, inherited from the same evolutionary ancestor, were then identified.

They also identified the genes’ associations with a range of human intelligence, mental health and emotional processes. I specialise in studying and managing companion animal emotions at the University of Lincoln, and so I worked with the team to explore the psychobiological basis to these traits.

We identified 12 genes where there seemed to be a connection between dogs and humans that related to similar psychological functioning. Some of these were closely aligned in terms of the emotional responses they produced, for example responses related to non-social anxiety. However, in other cases the link was perhaps less obvious.

But we formed hypotheses that may explain the association. When we did this, we found logical reasons to support the similarities we saw in the genetic associations in humans and golden retrievers.

For example, the canine gene ADD2 was associated with fear of strangers, but in humans was related to depression. A key characteristic of depression in people is social withdrawal, so we suspect there may be a common genetic link, which manifests in dogs (who are generally hypersocial) as stranger anxiety.

Other potential associations were with human conditions that involved complex cognitive processes, like self reflection, which are not thought to occur in dogs. However, as we looked more deeply into the range of human associations we could identify potential reasons for even some of these associations.

For example, trainability in dogs tended to be linked to genes in humans that are connected to not only intelligence but also sensitivity about being wrong. As far as we know, dogs cannot project themselves and their circumstances in the abstract ways people can, but they can certainly vary in their sensitivity to unpleasant experiences. so this might form the basis of the common genetic root between the two species.

The results provide a great basis for future studies in comparative and evolutionary psychiatry. As, Eleanor Raffan, a vet and assistant professor of physiology who led the Cambridge side of this research, said: “The findings are really striking – they provide strong evidence that humans and golden retrievers have shared genetic roots for their behaviour. The genes we identified frequently influence emotional states and behaviour in both species.”

There are, of course, differences in the ways that humans and dogs experience their
emotions. A lot of human emotion is tied up in complex thought processes. However, that does not undermine the importance of related conditions that might reflect mental health or suffering.

Enoch Alex, the first author of the report and a PhD candidate in the department of physiology, development, and neuroscience, summed this up: “These results show that genetics govern behaviour, making some dogs predisposed to finding the world stressful. If their life experiences compound this, they might act in ways we interpret as bad behaviour, when really they’re distressed”.

Although it might be tempting to sometimes dismiss academic work on dogs as somewhat frivolous, in this new work, there are hints at an important new role for dogs in our shared society: as natural models of mental health issues.

The demands of young people went unfulfilled by the UN climate summit – mostly

Source: The Conversation – UK – By Susan Ann Samuel, PhD Candidate, School of Politics and International Studies, University of Leeds

At the UN climate conference Cop30 in Belém, Brazil, I asked some young climate activists and negotiators about their hopes, expectations and demands. Despite their positivity and the push for action from climate movements, Indigenous people and civil society, a lack of consensus on key issues was palpable.

Following overnight negotiations on November 21-22, the Brazilian presidency unveiled an outcome decision referred to as the “global mutirão” (collective efforts). But experts agree that the outlined climate action is insufficient.

I attended this years’ Cop as an advisor to the international Youth Negotiators Academy — a programme offering training to negotiators under the age of 35. My experience at Belém informs my PhD research into how social movements are influencing climate conferences. Here are some of the expectations of the young people I met at Cop30.

Brazilian student Ana Bertazzo Lemos, 23, attended Cop30 calling for obligations to cut fossil fuel emissions and the integration of ecological action into everyday life. But the final Cop30 text had no mention of fossil fuels.

Without a roadmap to transition away from fossil fuels, the Brazilian presidency said it will move forward outside the UN process. Accordingly, the first International Conference for the Phase-out of Fossil Fuels will be held in Colombia in April 2026.

Equality for Indigenous people

Matthaeus Menezes Assef, 29, from Guarujá, Brazil, is the student representative of the UN Framework Convention on Climate Change (UNFCCC) taskforce at the University of Leeds. I talked to Menezes and Guarany Osório, a Brazilian professor of sustainability, about their common goals.

Menezes is concerned for Brazil’s domestic political vision. He says Brazil needs to deal with deforestation and oil extraction in the Amazon, while evolving as a climate leader. He was happy that Cop30 brought 3,000 Indigenous people to Belém, with many receiving blue badges for direct access to negotiations. However, a roadmap to deforestation did not materialise at Cop30.

Protection for Amazonia

Jhulielson Conceição, 22, and Nathália Vasques, 24, were volunteers at Cop30, providing essential information and guidance to delegates. “Without us they’ll be lost,” Vasques told me. She sees Cop30’s location as crucial because Belém is on the frontline of climate change.

Vasques hoped that first-hand experience for delegates would translate into stronger commitments and greater protection for Amazonia, but this hasn’t happened yet. Both Conceição and Vasques wanted to see more recognition for youth voices at future Cops — but this shouldn’t just be tokenistic. Young people require decision-making power.

Stronger climate law

Emily Zinkula, 25, a law student from Stanford University, focused on whether legal mechanisms can create accountability for climate action. She tracks whether negotiations incorporate the recent advisory opinions on climate obligations, particularly by the International Court of Justice. An advisory opinion is a legal interpretation that’s not legally binding, provided by a high-level court or tribunal in response to a specific question of law.

Zinkula spoke at a side event alongside Jojo Mehta, co-founder of the campaign organisation Stop Ecocide International. Zinkula argued that the advisory opinion can help civil societies gain momentum around recognising ecocide (large-scale destruction of nature by human actions) as an international crime.

Having researched climate laws, I share her vision for accountability and justice – but the negotiations don’t yet reflect that.

A healthy just transition

Nova Tebbe, 28, a postdoctoral researcher from the Global Climate and Health Alliance and UNFCCC constituency member, called for the introduction of “indicators for adaptation” – the rules, metrics and standards needed for adaptation projects.

Tebbe demanded adaptation finance from developed to developing countries as per the Paris climate agreement. She emphasised that human health should be central to climate negotiations, and hoped for a just transition mechanism that moves from policy to implementation.

Tebbe also wanted the second global stocktake (a five-yearly assessment of the world’s progress toward the goals of the Paris agreement, due in 2028) to be more inclusive, with civil society input. She told me how the Belém conference’s positive atmosphere and push for quick decisions seemed unusual compared with other climate summits she had attended.

However, the final outcomes of Cop30 did not offer reassurance on most of her hopes. A new just transition mechanism was adopted, but without any map, money or manual.

This mechanism is a strategy to guarantee that the global shift towards a green economy is equitable and safeguards the rights of all people. There were discussions about doubling adaptation finance by 2025 and tripling it by 2035 – but whether the adaptation indicators include priorities for health is yet to be seen.

Young climate activists can’t deny that climate negotiations are complex, driven by political agendas and national interests. But my time in Belém has reinforced something essential: young people can play an instrumental role in and around the negotiations. Unfortunately, those demands don’t always translate into actual outcomes.
