Maladies auto-immunes et microbiote intestinale sont liés 2721

On a maintenant la certitude que des maladies auto-immunes peuvent être causées par le microbiote. On a identifié les similarités entre des métabolismes produits par des bactéries et des métabolismes qui sont des molécules humaines classiques, et qui pourraient tromper le système immunitaire et déclencher des maladies auto-immunes. Une étude américaine publié en 2018 a en particulier renforcé cette certidude en établissant un lien clair entre les maladies auto-immunes et une bactérie intestinale dénommée « Enterococcus gallinarum ». Celle-ci favorise le développement de réactions inflammatoires chez la souris comme chez l’homme. Au-delà des perspectives d’une action thérapeutique efficace contre ces bactéries, cette nouvelle démontre bien, une fois de plus, que l’être humain est un écosystème complexe composé de cellules humaines et de micro-organismes où la frontière entre l’individu, le soi, et son environnement proche et intime, le non-soi, est impossible à séparer. Le corps humain se protège des agressions extérieures (provenant de bactéries, virus, champignons…) grâce à un système de défense organisée, le système immunitaire. Ce dernier est susceptible de se dérégler de plusieurs façons. Il peut soit : - s’affaiblir et ne plus résister aux bactéries et aux virus, c’est l’immunodéficience ; - donner une réponse excessive contre des substances provenant de l’environnement (pollens, produits chimiques, médicaments…), c’est l’allergie ; - considérer notre propre organisme comme un ennemi et l’attaquer dans un processus que l’on pourrait qualifier de « suicide physiologique » ou d’auto-destruction, ce sont les maladies auto-immunes (comme la polyarthrite rhumatoïde, le psoriasis, la sclérose en plaque, la myasthénie la maladie de Basedow – hyperthyroïdie -, le diabète de type 1, la spondylarthrite, la maladie cœliaque ou intolérance au gluten, la maladie de Crohn …) LES RACINES DU MAL DANS L'INTESTIN ? Des chercheurs de l’Université de Yale, aux Etats Unis, se sont intéressés à une bactérie intestinale, Enterococcus gallinarum, qui a pour particularité de pouvoir migrer de l'intestin vers des ganglions lymphatiques, le foie ou la rate. Ils ont découvert que lorsque l’Enterococcus gallinarum se trouvait à l’extérieur de l’intestin de souris prédisposées à des maladies auto-immunes, il provoquait une inflammation et surtout stimulait la production d’auto-anticorps – des molécules biologiques – qui s’attaquent à nos cellules. Les chercheurs ont observés aussi les mêmes effets de cette bactérie sur des cellules humaines in vitro. Bien plus, la présence de cette bactérie a été mise en évidence dans le foie de personnes souffrant d’une maladie auto-immune, mais pas chez des personnes en bonne santé. DES PERSPECTIVES THERAPEUTIQUES CONTRE LES MALADIES AUTO-IMMUNES ? D'autres expériences ont montré ensuite qu’il était possible de supprimer la réaction nocive auto-immunitaire chez la souris avec un antibiotique (vancomycine) ou un vaccin ciblant E. gallinarum. Les deux thérapeutiques arrêtent la croissance de la bactérie dans les tissus et réduisent l’activité auto-immune. Ces traitements ouvre des perspectives dans la résolution des maladies auto-immunes selon les auteurs de cette étude : la mise au point chez l’humain d’un vaccin spécifique contre la bactérie E. gallinarum pourrait améliorer la vie des patients atteints d'une maladie auto-immune, en particulier dans deux maladies rares, le lupus et l'hépatite auto-immune. La vaccination contre d'autres bactéries étudiées dans cette recherche n'a pas eu par contre d’effets positifs. Il faut souligner que cette implication de bactéries intestinales dans les maladies auto-immunes est soupçonnée déjà depuis un certain nombre d’années sans qu’on arrive à en comprendre encore le mécanisme exact. Ainsi, les inflammations de la polyarthrite rhumatoïde précoce sont associées à un profil altéré de la colonisation microbienne de l’intestin. Plus largement, l’helicobacter pylori (une bactérie commune dans l’estomac), dont on sait déjà qu’elle est directement impliquée dans la survenue de cancers, aurait un lien avec de nombreuses pathologies auto-immunes. On considère d’ailleurs qu'aujourd'hui au Maroc, par exemple, une personne sur deux est porteuse de cet agent infectieux et que 10 % d'entre elles développeront des infections gastriques sérieuses comme les ulcères ou les gastrites chroniques. Des relations de cause à effet sont bien établies aussi entre certains streptocoques, (des bacilles présents fréquemment notamment dans la bouche et les intestins) et le rhumatisme articulaire : à partir d’une simple angine non traitée, des attaques auto-immunes vont survenir, pouvant toucher le cœur, les articulations, le système nerveux central ou la peau, avec de graves conséquences potentielles au niveau des valves cardiaques ou du système nerveux central. LE MICROBIOTE UN CENTRE DE GRAVITE DE L’ORGANISME Notre microbiote intestinal contribue donc au fonctionnement de notre organisme. L’homme n’héberge pas seulement un mais plusieurs microbiotes (cutané, des voies oro-pharyngées, vaginal …) exerçant aussi ce rôle primordial. Le microbiote intestinal est l’ensemble de la microflore résidant dans l’intestin. Le nombre de bactéries est de 100 000 milliards de bactérie, soit 10 fois le nombre de cellules de l’organisme ! Il comporte environ 100 fois plus de gènes que le génome humain. Chaque individu possède un microbiote qui lui est propre : il s’agit d’une vraie carte d’identité biologique. Ce dispositif a des fonctions capitales de protection contre la colonisation par d'autres bactéries, de production de molécules antibactériennes, d'aide à la maturation du système immunitaire et d’induction de la réponse immunitaire.

What is the most expensive liquid on Earth? 5782

Anas Bedraoui, 2 y.
Imagine a liquid so precious that just a small droplet could be worth more than a diamond. This isn’t a scene from a science fiction story; it’s reality, and the liquid is scorpion venom. Scorpion venom is potentially the most expensive liquid on Earth, with prices soaring to millions of dollars for just one gallon. But what makes it so incredibly valuable? Scorpions, those small, often feared creatures, carry in their tails a venom used for defense and hunting. Extracting this venom is a meticulous and often hazardous task. Specialists must carefully ‘milk’ the scorpions, a process that involves stimulating the scorpions to release their venom, which is then collected drop by drop. This labor-intensive method, combined with the venom’s scarcity, drives its high cost. But the price tag is not just due to the danger and difficulty of extraction. The real treasure of scorpion venom lies in its composition and potential to revolutionize medicine. Scorpion venom is a cocktail of numerous compounds, including peptides and proteins, each with specific effects. For instance, chlorotoxin, found in the venom of the deathstalker scorpion (Leiurus quinquestriatus), shows promise in targeting cancer cells, making it a beacon of hope for new cancer treatments. Another component, called scorpine, has been studied for its antimicrobial properties and its potential to combat malaria. Researchers are intrigued by how these compounds can lead to breakthroughs in drug development. Imagine a new kind of painkiller derived from scorpion venom that could offer relief without the side effects of current medications, or innovative treatments capable of combating autoimmune diseases and even halting the spread of cancer. These are not just hopeful speculations but real possibilities being explored in labs around the world. The process of transforming venom into medicine is complex and involves identifying and isolating the active components, understanding their mechanisms of action, and then synthesizing them in forms suitable for medical use. Despite the challenges, the potential health benefits drive scientists and pharmaceutical companies to invest in this research. This intricate dance of danger, rarity, and medical promise makes scorpion venom more than just an expensive liquid; it’s a symbol of the incredible potential hidden in nature, awaiting discovery. In a world where answers to some of our biggest health challenges might be found in the most unexpected places, scorpion venom stands as a testament to the wonders of the natural world and human ingenuity’s boundless curiosity.

Athletics got off to a flying start at the 13th All-Africa Games, and the Games took on a whole new dimension as the level of athletics in Africa is so much higher than in other sports. There will certainly be plenty of Olympic medallists among the participants in Paris next summer. Despite the hot and humid weather in Accra at this time of year, the quality of the track and the perfect organisation of the competitions enabled promising performances to be achieved in almost all the events from the very first day of the qualifiers, with many Games records, continental records and even more national records. First day results: It start with an ethiopian win in the women 5.000m: U20 Medina Eisa won women 5000 m in 15:04.32 (third best ever time at Games) over teammates Birtukan Molla 15:05.32 PB and Melknat Wudu 15:07.04. Fourth best Kenyan steeple WR holder Beatrice Chepkoech 15:13.71. In men steeple Samuel Firewu also from Ethiopia won the gold with a time of 8:24.30 ahead of Kenyans Amos Serem 8:25.77 and Simon Kiprop 8:26.19. South African Victor Hogan dominated in discus with 62.56. From prelims to note fastest 100 m men semifinal 10.15 (-0.1) by Cameroon´s Emmanuel Eseme. In women 100 m semfinal Gina Bass from Gambia 11.35 (-0.8). 400 m first round had Cheikh Tidiane Diouf from Senegal as fastest with 45.64. Eritrean Fithawi Zaid clocked in 800 m prelims national record 1:45.90. Senegal´s Louis Francois Mendy topped 110 m hurdles first round with 13.54 (-1.2). In women 400 m heats fastest Esther Joseph from Nigeria 51.81 with World champion over 800 m Mary Moraa winning her heat 52.18. World Indoor champion Tsige Duguma was the fastest in women 800 m opening round 2:02.08.

Digital: The perfect undying art 6085

Tariq Daouda, 2 y.
Great paintings deteriorate, great statues erode, fall and break, great literature is forgotten and it's subtleties lost as languages for ever evolve and disappear. But now we have a new kind of art. A type of art that in theory cannot die, it transcends space and time and can remain pristine for ever and ever. That is digital art. Digital art is pure information. Therefore it can be copied for ever and ever, exactly reproduced for later generations. Digital art cannot erode, cannot break, it is immortal. Thus is the power of bits, so simple zeros and ones and yet so awesome. Through modern AI and Large Language Models we can now store the subtleties of languages in an abstract vectorial space, also pure information, that can be copied ad infinitum without loss of information. Let's think about the future, a future so deep that we can barely see it's horizon. In that future, with that technology we can resurrect languages. However the languages resurrected will be the ones we speak today. We have a technology that allows us to store reliably and copy indefinitely that technology is called the *Blockchain*. The most reliable and resilient ledger we have today. We have almost everything we need to preserve what we cherish. Let's think of a deep future.

Beyond Good and Evil 5688

EL MONO MAS GRANDE, 2 y.
He smelled it before he could see it. A beast so ugly it only vaguely resembled a man. Hairy, disproportionate, caked with dirt and angry. In everything following it's emotions. In everything following it's passion. Never as second thought. The beast was strong physically and yet so weak. In it's eyes, the ape saw fear. A fear so deep it drowns worlds. A deep seated anxiety shaking the roots of being. -"Confusion", said the biggest ape. -"That one knows not good'", answered the crow. Wisest among the birds. -"Take me to the second one", said the biggest ape. Now before him stood the most beautiful man. He was perfect in every way, perfect in proportions, perfect in intellect, perfect in movement. He was surrounded by beauty. Around him beauty blossomed. Everything was made perfect by his hands, and yet it decays. Around him everything was dying. Oh so slowly, but oh so certainly. At his feet, blood. -"That one knows good", said the crow. -"Take me to the third one", said the biggest ape. There sat a man, eyes closed with a faint smile on his lips. As hard as he looked, the ape couldn't make up the limits of his body. His body was translucent light, filled with every changing colors. In him he saw the beast, in him he saw the most perfect man. And all the intermediary steps. There he sits for ever, and ever. Eternal. -"That one knows no good nor evil", said the crow. -"Yes" Thus spake Apathustra.

Picture this: you’re at a barbecue, and instead of the usual chat about sports or the weather, someone drops into the conversation that they work with snake venom and AI. It might sound like they’re pulling your leg, but actually, they’re on to something groundbreaking. Welcome to the Future: Where AI Meets Venom Toxinology and venomics aren’t just cool words to impress your friends; they’re fields where scientists study toxins and venoms from creatures like snakes and spiders. Now, mix in some AI, and you’ve got a dynamic duo that’s changing the game. With AI’s smart algorithms, researchers can sift through massive amounts of data to uncover secrets about venom that could lead to medical breakthroughs. It’s like having a detective with a magnifying glass, except this one’s scouring genetic codes instead of crime scenes. Why We Should Care Venoms are nature’s way of saying, “Don’t mess with me.” But beyond their bite or sting, they’re packed with potential for new medicines. Understanding venom better can help us find new ways to treat diseases, from blood disorders to chronic pain. And AI is the super-efficient helper making these discoveries at lightning speed. The Nitty-Gritty: How AI Works Its Magic Imagine AI as the Sherlock Holmes of science, able to analyze venom components, predict their effects, and uncover new ones that could be game-changers in medicine. For instance, if there’s a venom that can thin blood without harmful side effects, AI can help pinpoint how to use it for people at risk of blood clots. Or if another venom targets pain receptors in a unique way, AI could help in crafting painkillers that don’t come with the baggage of current drugs. From the Lab to Real Life There are some standout AI tools like TOXIFY and Deep-STP that are making waves in venom research. These tools can figure out which parts of venom are worth a closer look for drug development. It’s like having a filter that only lets through the most promising candidates for new medicines. Looking Ahead With AI’s touch, the potential for venom in medicine is just starting to unfold. We’re talking about new treatments for everything from heart disease to chronic pain, and as AI tech advances, who knows what else we’ll find? The Fine Print As exciting as this all sounds, there are hurdles. Getting the right data is crucial because AI is only as good as the information it’s given. Plus, we need to consider the ethical side of things, ensuring our curiosity doesn’t harm the creatures we study or the environments they live in. In Summary: It’s a Big Deal The combo of AI and venom research is turning heads for a reason. It’s not just about finding the next big thing in medicine; it’s about opening doors to treatments we’ve hardly imagined. And it’s a reminder that even the most feared creatures can offer something invaluable to humanity. So, the next time someone mentions using snake venom in research, you’ll know it’s not just fascinating — it could very well be the future of medicine, with AI leading the way. And that’s something worth talking about, whether you’re at a barbecue or anywhere else. Reference: Bedraoui A, Suntravat M, El Mejjad S, Enezari S, Oukkache N, Sanchez EE, et al.

Augmented Reality (AR) has been identified by educational scientists as a technology with significant potential to improve emotional and cognitive learning outcomes. However, very few papers highlighted the technical process of creating AR applications reserved for education. The following paper proposes a method and framework for how to set up an AR application to teach primary school children the basic forms and shapes of atoms, molecules, and DNA. This framework uses the Unity 3D game engine (GE) with Vuforia SDK (Software Development Kit) packages combined with phone devices or tablets to create an interactive App for AR environments, to enhance the student’s vision and understanding of basic chemistry models. We also point out some difficulties in practice. As for those difficulties mentioned, a series of solutions plus further development orientation are put forth.

Decoding Performance: The Brain of Professional Soccer Players and Stress 5651

Simo Idrissi, 2 y.

3.4 min read.
In a hypothetical narrative, considering two soccer players, each playing for a different team. Player A is part of a team with an average performance, having lost 18 games, tied 6, and won 4. Player B, on the other hand, plays for a team with a lower performance record, having lost 19 games, tied 8, and won just 1. Both players had to play 4 more games, and both teams need to win all four or risk being relegated to a lower level. The coaches of both teams have prepared overview and analysis slideshows for the players to study, enabling each player to grasp the tactics and individual performance of their opponents. These opponents exhibit high performance both tactically and physically. The characteristics of the three top teams are high speed, accurate indirect play, and individual techniques. Furthermore, the news certainly portrays these three teams as heroes that can conquer any challenge. The game statistics reveal that the three top teams have won 22 games, and the standings difference is only 1 point at the top of the list. Now, Players A and B must think, perhaps even overthink, about how to enhance their performance to counter these formidable opponents. Picture these two players in a different game location standing in line, waiting for the referee to lead them onto the pitch. In this moment, Players A and B, each in a different location and game, experience their body’s primal response, orchestrated by a fascinating interplay between three key brain regions: the amygdala, hypothalamus, and cortex. The amygdala acts like a fire alarm, but for challenges, not just threats. It constantly scans situations based on past experiences. When it detects a tough opponent, like a highly skilled soccer team, it triggers a response to prepare you for the challenge. It receives sensory information from the eyes, ears, and other senses. In response to detecting a high-pressure situation, like playing against the top three opponents, the amygdala triggers a rapid response based on past experiences. This initial response is quick and prioritizes preparing the player for action, without the deep analysis that the cortex can provide. Over time, the amygdala has established a rapid response system that plays a vital role in survival. This system helps players react instinctively in complex situations like facing top competitors. The amygdala then transmits the data to the hypothalamus, the brain's control center. Acting like a dispatcher, the hypothalamus mobilizes various bodily systems for action. It triggers a cascade of physiological changes, including increased heart rate, sweating, or heightened muscle tension, all designed to enhance performance in the face of a challenge. Additionally, the hypothalamus can also stimulate the release of hormones from other glands that can influence mental state, such as increased alertness and focus, further preparing the player for the high-pressure situation. A key hormone involved is adrenaline (epinephrine), released by the adrenal glands in response to signals from the hypothalamus. Adrenaline prepares the body for action by increasing heart rate, sweating, and muscle tension. Beyond Adrenaline and Cortisol: The presence of adrenaline in the bloodstream triggers a cascade of hormonal responses: Cortisol: As mentioned earlier, adrenaline stimulates the hypothalamus to release cortisol from the adrenal cortex. Cortisol plays a vital role in managing stress by increasing blood sugar for energy, suppressing non-essential functions like digestion, and contributing to heightened alertness. Sex Hormones: In males, short-term stress might lead to a temporary increase in testosterone levels, providing a burst of energy mobilization. However, chronic stress can have the opposite effect, causing a decrease in testosterone levels. Females might experience changes in estrogen and progesterone levels as well, depending on the situation. Antidiuretic Hormone (ADH): This hormone, released from the pituitary gland in response to signals from the hypothalamus, helps conserve water by reducing urine production during stressful situations. Overall Impact: This complex interplay of hormones, initiated by the amygdala and orchestrated by the hypothalamus, prepares the player both physically and mentally to face the challenge. But here's where things get interesting. The amygdala's initial alarm might be loud, but it doesn't have the final say. The player's prefrontal cortex (PFC), the brain's reasoning center, steps in to analyze the information it receives from the amygdala. This analysis considers past experiences and memories, the context of the situation (such as assessing the opponent's potential to outperform them) and evaluates potential solutions to maintain composure and prevent self-esteem from taking a hit. Here's where individual differences become crucial. Player A, with their well-developed emotional intelligence, might interpret these thoughts and manage their behavior differently from Player B, who might struggle to express their true emotional state. Based on this analysis, the PFC can now interpret the information received from the amygdala, considering the player's knowledge and experience (intelligence can be a broad term). If the PFC judges the competition as manageable pressure, it can signal the hypothalamus to downregulate the fight-or-flight response, effectively calming the amygdala's initial alarm. This communication process can trigger self-talk that might translate into an affirmation like: Give it my all and avoid mistakes. However, if the cortex recognizes a high-pressure situation (such as facing one of the top three teams, known for their excellent performance and currently in top form), it may not be able to completely suppress the amygdala’s alarm response. This could lead to players experiencing intense pressure, resulting in a decrease in innovation and organization during the game. They might even feel an overwhelming need to surmount these challenges, which could further intensify their reactions. The good news is that this system is adaptable. By repeatedly encountering situations that were initially perceived as high-pressure but ultimately safe (like playing against opponents similar to the top three teams who they were able to defend against), the amygdala and cortex can learn and adapt. These experiences weaken the initial fear response, making players less likely to react impulsively in similar situations in the future. These experiences weaken the initial fear response, making players feel less random to react in similar situations in the future. This is why exposure therapy (training sessions) can be effective in managing high performance, especially at elite or professional levels. Simo Idrissi

AI+Health: An Undelivered Promise 5998

Tariq Daouda, 2 y.
AI is everywhere, or so would it seems, but the promises made for Drug Discovery and Medicine are still yet to be fulfilled. AI seems to always spring from a Promethean impulse. The goal of creating a life beyond life, doing the work of gods by creating a new life form as Prometheus created humanity. From Techne to independent life, a life that looks life us. Something most people refer to as AGI today. This is the biggest blind spot of AI development. The big successes of AI are in a certain way always in the same domains: - Image Processing - Natural Language Processing The reason is simple, we are above all visual, talking animals. Our Umwelt, the world we inhabit is mostly a world of images and language, every human is an expert in these two fields. Interestingly, most humans are not as sound aware as they are visually aware. Very few people can separate the different tracks in a music piece, let alone identify certain frequencies or hear delicate compressions and distortions. We are not so good with sound, and it shows in the relatively less ground breaking AI tools available for sound processing. The same phenomenon explains why AI struggles to achieve in very complex domains such as Biology and Chemistry. At it's core, modern AI is nothing more than a powerful general way to automatically guess relevant mathematical functions describing a phenomenon from collected data. What statisticians call a *Model*. From this great power derives the domain chief illusion: because the tool is general, therefore the wielder of that tool can apply it to any domain. Experience shows that this thinking is flawed. Every AI model is framed between two thing: its dataset (input) and its desired output as represented by the loss function. What is important, what is good, what is bad, how should the dataset be curated, how should the model be adjusted. For all these questions and more, you need a deep knowledge of the domain, of the assumptions of the domain, of the technicalities of the domain, of the limitations that are inherent to data collection in that domain. Domain knowledge is paramount, because AI algorithms are always guided by the researchers and engineers. This I know from experience, having spent about 17 years closely working with biologists. Pairing AI specialists with domain specialist with little knowledge of AI also rarely delivers. A strategy that has been tested time and time again in the last 10 years. Communication is hard and slow, most is lost in translation. The best solution is to have AI experts that are also experts in the applied domain, or domain experts that are also AI experts. Therefore the current discrepancies we see in AI performances across domains, could be layed at the feet of universities, and there siloed structures. Universities are organized in independent departments that teach independently. AI is taught at the Computer Science department, biology at the Biochemistry department. These two rarely meet in any substantial manner. It was true went I was a student, it is still true today. This is one of the things we are changing at the Faculty of Medical Science of the University Mohammed VI Polytechnic. Students in Medicine and Pharmacy have to go through a serious AI and Data science class over a few years. They learn to code, they learn the mathematical concepts of AI, they learn to gather their own datasets, to derive their hypothesizes, and build, train and evaluate their own models using pyTorch. The goal being to produce a new generation of scientists that are intimate with their domain as well as with modern AI. One that can consistently deliver the promises of AI for Medicine and Drug Discovery.

What Happens If You Swallow Snake Venom? 5438

Imagine you're hanging out with friends, and someone randomly asks, "Would swallowing snake venom kill you?" It sounds like the start of a dare or a myth you'd want to debunk right away. Snake venom is nature's own brew of toxic substances designed for defense and catching dinner. It's filled with proteins and enzymes that can cause serious trouble if they get directly into your blood, affecting everything from your nerves to your circulatory system. But here's where it gets interesting: the method of venom entering your body makes a huge difference. And when it comes to swallowing venom, the story takes an unexpected turn. Swallowing snake venom? It might not be as deadly as you think. Our digestive system is pretty robust, breaking down proteins and peptides, which are the main components of venom. Essentially, if venom ends up in your stomach, your body starts to digest it like any other protein-rich food. However, it's not an open invitation to start a venom-tasting club. The real risk comes if there are any cuts or sores in your mouth or throat that could give venom a fast pass into your bloodstream. That's when the situation could turn dangerous. Venom's power is unleashed when it bypasses the digestive system, entering directly through a bite. This direct route to your bloodstream means venom can quickly get to work, potentially leading to severe, even life-threatening, reactions. Interestingly, the medical world sees snake venom not just as a danger but as a source of potential breakthroughs. Scientists study venom's components to develop treatments for conditions that are currently hard to manage. It's a classic example of how something potentially deadly can be turned into a lifesaver. Back to the original question: swallowing snake venom isn't something to put on your bucket list, but it's unlikely to be lethal due to the protective role of your digestive system. The real concern is venom entering directly into your bloodstream, whether through an existing wound in your mouth or a snake bite.

Mustapha Guiliz: The door ajar... 5898

Aziz Daouda, 2 y.
"In writing this book, I aspire to a more humane form of justice, one that ensures equality between citizens, but also the right to fulfil oneself." This sentence, full of meaning and questions, is by Si Mustapha Guiliz. It is taken from the article that the newspaper "L'économiste" devoted on 3 January 2024 to the presentation of the book "les hommes de la nuit" published by Orion, whose founding president is none other than Si Abdelhak Najib. The article is followed by an edifying interview with Si Mustapha Guiliz, the author of the book. This is an author whom Bluwr readers and members have had the privilege of meeting and, above all, appreciating through his article "Education through values", which appeared in Bluwr few weeks ago. Si Mustapha GUILIZ is a teacher and writer who has already written "Le Monde d'Brahim" and "Au pays des sources". Contrary to the title of the book, which might suggest that the author is a dull, even embittered character, Si Mustapha is a pleasant person, with a youthful smile that is pleasant, fulfilled, indulgent and tender. When you come into contact with him, you realise just how far removed he is from the subjects he covers. This detachment, which is both intelligent and not at all indifferent, allows him to go into the depths of things with the objectivity that is both necessary and required. Having had an hour-long discussion with Si Mustapha one fine morning last November, I was able to gauge and appreciate his detachment and depth of philosophical analysis. "The men in my book are men with a capital M, who have made the best of life in the dark," he says. In fact, for Si Mustapha, all men deserve a name with a capital M, and not just the characters in his inspired fiction. In a world of injustice, he dreams of justice. In a world where women suffer, he dreams of ideal conditions for them all. In a world of abused power, he dreams of moderation and balanced power. In a world of despair, he dreams of fulfilment. Is he an idealist from another planet, the one on which he sails to bring his characters to life? He is the only one to know ... In any case, this sentence "Through the writing of this book, I aspire to a more humane form of justice, one that aims to ensure equality between citizens, but also the right to fulfil oneself" fits his character perfectly. We need so many people like him to reveal our reality to us, but also to open the door to hope and to urge us to break it down. I'm writing these lines to congratulate Si Mustapha, whose book is a perfect start to this new year of service to the community, and to express my pride in knowing him and publishing articles with him on Bluwr, in the hope of reading him again soon on the platform.

El Salvador: The most important country you barely hear about 6077

Tariq Daouda, 2 y.
El Salvador has a significant diaspora, so much that money coming from the US is a major source of income. **Not so long ago you would have been pressed to find a Salvadorian who wanted to go back to El Salvador. Now things seems to be changing.** El Salavador, used to have one of the highest homicide rates in the Americas, now it looks relatively safe. El Salvador showed an interesting strategy. First boost the economy before handling the crime situation. Crime is indeed a part of GDP, albeit a hard one to quantify. Since it is an economic activity, it participates in exchanges and provides people with activities that supports them and their families. Drastically reducing crime has the effect of creating *'unemployed criminals'* people with a skillset that's hard to sell in a traditional economy. El Salvador probably did take a hit to its GDP, but that was compensated by the increase in economic activity and investments. Bitcoin was a big part of that. Bitcoin got a lot of bad press as a technology only used by criminals, or a crazy investment for crazy speculators. These takes failed to understand the technology and it's potential. What Bitcoin offers is a decentralized, fast and secure payment system for free. El Salvador doesn't have to maintain it, regulate it, or even monitor it. All very costly activities that a small country can do without. Bitcoin is a mathematically secure way of payment. In a country where road infrastructures are challenging, Bitcoin offers people in remote areas the possibility to pay their bills without travelling for hours. In a country that was unsafe, Bitcoin offered people the possibility to go out without the fear of being robbed. It also attracted a kind of investors that would go nowhere else. And even if these investment can appear small, for a country like El Salvador it's a big change. The Salvadorian experiment in a freer economy, crypto-friendly and smaller government, in a time of increasing inflation, has a lot of people watching. In a continent that leaned left for so long, this is a big change. My opinion is that there would be no Javier Millier hadn't there been a Nayib Bukele before. Argentina has been a bastion of the left for decades. If the libertarian policies of Millier succeed in bettering the lives of Argentinians, we might be on the brink of a major cultural shift in the Americas and then the world. Argentina is a far bigger country than El Salvador, with far more people watching.

A CROOKED TALE 6006

Pat01Butcher, 2 y.

2.9 min read.
This is a story about barbarians who destroyed an unusual and much loved pub in the west midlands of England. I wrote this tale some months ago for my website, www.globerunner.blog. Recent news suggest that the barbarians, as my article suggests are going to be forced to rebuild The Crooked House! Locals of a demolished pub near where I was born can take heart from the story of a demolished pub near where I live now - one which was ordered to be rebuilt ‘brick-by-brick’. Judging by calls and emails I’ve had from folks who know that I’m a Black Country boy, the news of the recent burning and demolition of the Glynne Arms, aka the Crooked House near Dudley in the English west midlands must have gone around the world. I was born a mile or so away from what we locals knew as the Siden (side-on?) House, and as our local gang of kids grew up in the 1950s and 60s, the pub was a regular curiosity for us to view as we roamed the countryside around the disused pit workings that had contributed to the Crooked House’s subsidence. Later on, I'd often run past it on one of my training stints on the disused railway track which overlooked it. My father had been born even nearer to the pub, and as I grew into drinking age, it would be on our itinerary for an occasional pint, and the traditional rolling of a ball-bearing seemingly ‘uphill’ on the bar or the window sills. It was also a must-see for anyone visiting the area. Now living in north-west London, the last time I was there was four years years ago, showing the place off to some French visitors who’d come to the family home to celebrate my mother’s 100th birthday. The story of the pub’s demise last weekend has been across the national news for days. Originally built as a farmhouse in the late 18th century, it had been a pub since the 1830s. Despite a campaign to preserve it as such, it was sold two weeks ago, apparently to be repurposed. The building then burned down last weekend in circumstances that the neighbourhood websites have universally described as SUSPICIOUS. The fire service arrived to find its way blocked by mounds of earth on the access road. The delays in getting high pressure fire hoses close enough to the blaze meant that the building had already been gutted by the time that fire was extinguished. Then, to pile anguish onto injury for the locals, bull-dozers were brought in the next day, to reduce the place to rubble. Drinkers, devotees and dignitaries across the West Midlands are up in arms, demanding explanation and restoration. They might take heart from the tale of the Carlton Tavern in Maida Vale, a couple of miles from where I live now. In 2015, the Carlton, which had been rebuilt as a pub in 1921, was bought by a company who turned out to be developers. An immediate application from them to build flats was turned down by Westminster Council; and alert locals sought a Grade II listing from Historic England, to prevent further threat to the pub. But two days before the listing was to be awarded, the new bosses gave staff a day off, allegedly for stock-taking, and avoiding the inconvenience of a fire in a residential area, the bulldozers were drafted in and reduced the pub to a shell within a few hours. Cue mayhem! But, as the Guardian reported two years ago on its reopening, ‘… the Carlton’s story did not follow the usual plot, where the developer presents the fait accompli to the local authority and pays a fine before pressing ahead with the redevelopment and counting their profits.’ Over 5000 locals, including councillors had mobilised to set up a campaign entitled Rebuild The Carlton Tavern. They pressured Westminster Council, not noted for its public spirit, and not only did the council turn down the developers’ further application for flats, they ordered the company to rebuild the Carlton ‘brick by brick’. That was a pleasant surprise for James Watson, the pub protection adviser for the Campaign for Pubs, who advised the Carlton group. “I never imagined that I would see a planning inspector order a developer to put back what he’d just knocked down, to look exactly as it was. I thought the developer would get a slap on the wrist, a £6,000 fine. But I was flabbergasted – and it has set an incredibly useful precedent. Other planning inspectors will remember it, and so will developers”. With hundreds of locals descending on the site of the former Crooked House in the last two days to bemoan and complain of its passing (and to take away a souvenir brick), pressure is only going to grow around the Black Country and West Midlands for something to be done about the wanton destruction of such an unusual historic landmark.  Roger Lees, the leader of South Staffordshire council has already confirmed it is investigating planning breaches, and the over-zealous destruction of the property, which his body had not authorised. Council and aggrieved locals could do worse than study the case of the resurrected Carlton Tavern. Could the Crooked House yet rise from the ashes?

Track and Field, the most representative sport on the African continent 5821

Aziz Daouda, 2 y.

3.6 min read.
4 months ago I published this article in French. Today, as I'm getting ready to leave for Accra for the All African Games, I thought it would be a good idea to republish it, this time in English. It's a reminder of the dynamism of African athletics and its place on the continent and the world stage. I am here using an old wording: instead of Athletics i used Track and Field as title...A kind of nostalgia of the old days. XXXXXXXXXXXXXXXXXXXXXXX One of Africa's most dynamic sporting bodies is the Confederation of African Athletics. This dynamism is obviously the result of the fact that it manages the continent's most representative sport, but it also comes from its component parts, which are of course the national federations, of which the CAA is simply an offshoot. Its role is to encourage, channel and coordinate efforts to develop athletics on the continent. Athletics is the sport that has won, is winning and will continue to win the most titles and glories for the continent for a long time to come. To this end, the CAA, under the leadership of its President Hamad Kalkaba Malboum, has made great efforts to develop the sport. It has succeeded in setting up an initial ten-year strategic plan, the objectives of which have almost all been achieved: in particular, revitalizing the most precarious national federations and developing youth sport by introducing regional and continental competitions for U18s. This plan was aimed at popularization and more quantitative aspects: number of countries and athletes taking part in African competitions, number of African countries and athletes taking part in world competitions. The 2nd plan, launched in 2019, also covers a ten-year period and aims to consolidate and strengthen the gains made by moving a little closer to the quality of the activity as a whole, by reducing the disparities between members and regions. Aware of the importance of scientific aspects for the development of athletics, the CAA has based a large part of its strategy on collaboration with universities in each of its member countries: for the training of executives and for research and development in governance and management. If Africa accounts for more than 35% of world athletics, it is because it also has close relations with the world body, which is done in perfect harmony. There are, of course, points of disagreement that the two parties are trying to overcome to ensure perfect complementarity. World Athletics has delegated a number of prerogatives to the CAA, including development. This policy of decentralization is working rather well, to the satisfaction of both parties. The CAA's other major partner is ANOCA (Association of National Olympic and Sports Committees), with which we are in the process of establishing a close working relationship. ANOCA is the IOC's arm on the continent. This body, which has a major impact on sporting activity on the continent, particularly since it took over responsibility for the All-Africa Games, has entrusted the task of developing sport in Africa to M Hamad Kalkaba Malboum, President of the CAA. The athletics development model thus inspires all sports in Africa. A great deal of cooperation has also been undertaken with the African Union, which is linked to the CAA by a very important agreement with multiple objectives. Of course, the AAC will not succeed without collaboration with its members, their respective governments and the respective NOCs. Funding remains the major challenge. It is difficult to put forward figures as it is impossible to compile all the money spent or invested in athletics. We have the involvement of local authorities, governments and the NOCs, as well as what is certainly a very significant contribution from individuals and civil society through associations and clubs. If today athletics is practiced in all 54 African countries and all of them take part in continental competitions, it is because this is accompanied by substantial budgets. But more is still needed. Paradoxically, there are some countries, without naming them, that invest more than 10 million dollars a year in the running of their athletics federation and hundreds of millions in infrastructure. Others don't spend more than 20 or 30 thousand USD. This is understandable, given the GDP of some countries and the lack of interest shown by some governments in athletics, even though it is the most basic of sports. Funding is made difficult in many countries by the weakness of the economic fabric, characterized by monopolies, low levels of consumption and the stranglehold of certain multinationals, which make no effort to promote local development and are far from supporting the development of young people through sport. CAA has placed youth development at the heart of its strategy. It has made this its exclusive mission. It believes that the development of athletics on the continent must be centered on the athlete. Based on this philosophy, management training is a key lever. Young people need to be supervised by competent managers. As a result, it now has eight centers whose mission is to train managers as well as athletes. These are known as AADC: African Athletics Development Centers. And it's working so well that new centers are being planned. A center has just been launched in Abidjan in 2023 and another is about to be launched in Praia, Cape Verde, for Portuguese-speaking countries. This is how CAA, its partners and member federations are responding to the pressing need for development, by bringing its actions closer to the beneficiaries. The CAA has also signed agreements with federations in "wealthy" African countries to ensure that their infrastructures and know-how benefit the "less wealthy". In particular, it has signed an agreement with the Royal Moroccan Federation and with those of Ethiopia and South Africa. The CAA has also set up training units in more than one country. These are groups of talented youngsters who train under the guidance of qualified coaches appointed by the CAA. All financed by the CAA. The aim is to improve standards in the continent's least developed events and to help countries that are having difficulty setting up a good athlete training system. The CAA believes that African athletes should have the opportunity to compete on the continent, and has thus ensured the continuity of a competition system that Covid has unfortunately disrupted. In addition to the African championships in three age categories in cross-country and athletics, the CAA organizes an African Tour of one-day meetings in three categories Gold, Silver and Bronze, in addition to the Diamond League in Rabat, the Kip Keino Classic in Nairobi and the Botswana Golden in Gaborone.

Abdou Cherif left, carried by his voice towards the heavens. 6607

I was driving back from Fez, when the radio channel which kept me company announced the sudden, dramatic, incomprehensible, unexpected, rapid, devastating and sad disappearance of Abdou Cherif. I adored, I adore and will adore until the end of my days this virtuoso whom I never had the chance to meet but whom television and YouTube subsequently made me discover and love. I, who adore Abdelhalim Hafed or Hafez and the beautiful Egyptian songs, find in him a certain continuity of the "belle époque"; that of the sublime musical drop; the one where lyricists like composers, conductors and performers surpassed themselves to offer the Arab public and not only the best of music. Inspired sometimes by deeply rooted popular arts, sometimes by musical tunes from elsewhere, even going so far as to explore Argentina Tango, they have bequeathed us a unique musical heritage whose richness we do not yet fully appreciate. Listening to Abdou Cherif performing Gabar or habibaha, we are caught in a whirlwind of magic by his captivating voice, strong, soft, expressive. The sound is crystal and the diction clear. Abdou sublimates this kind of song to make you forget the original… And then big surprise, one evening, at the Olympia in Cairo, he doubtfully gently announced that he was going to venture into singing "La Boheme". Charles Aznavour would have loved this moment so much. It was a triumph. And it's not over, Abdou will try the impossible and no one is bound to do the impossible, one evening in Casablanca he will amaze, surprise, by revisiting one of the standards of Moroccan Malhoum: Ghita. Who would have thought that one day this inveterate faithful of Abdelhalim would knock on the door of Lhaj Driss Benali Al malki and make him stand up in his two centuries old tomb. I am convinced that where he is, Driss Benali is smiling with satisfaction. No one has ever interpreted Ghita like Abdou Cherif, not even the great master Driss Toulali. This is the man who leaves us today forever, leaving us his voice, his smile, his elegance, his sensitivity and his audacity to stand up in large concert halls and take his fans on a journey beyond time. . When I arrived home, I stood in a corner, took my phone and started listening to endless extracts of his interpretations, spending more time on some where he had been at the height of his art, such as Rahila, composed by another of Moroccan music: Abdesalam Amer and performed by another beautiful voice that of the crooner Mohamed ElHayani. He also left early. A way of the deceased Abdou Cherif from a distance and to pray for the peace of his soul. I hesitated before offering you any of his interpretations: all of them are as perfect and beautiful as each other. Finally I said to myself why not Bohemia. You have a link down here. We belong to God and to him we return. Rest in peace Abdou.

I have been to more scientific conferences than I can count. From to smallest to the biggest like NeuRIPS (even back when it was still called NIPS). Of all these events AMLD Africa is my favorite, by far. I first met the team two years ago when they organized the first in-person edition of the conference at the University Mohammed VI Polytechnic. I was immediately charmed by the warmth and professionalism, ambition and fearlessness of the team. So much that I joined the organization. AMLD Africa is unique on every aspect. By its focus on Africa, by its scope and ambition, by its incredibly dynamic, young, passionate, honest and resourceful team, all volunteers. It is hard to believe that this year in Nairobi was only the second in-person edition. AMLD Africa does the impossible without even realizing it. It has an old school vibe of collegiality, community and most importantly **__fun__** that is so lacking in most conferences today. All without compromising on the quality of the science. It offers one of the best windows into everything AI and Machine learning happening in Africa. Africa is a continent on the rise. But a very hard continent to navigate because of information bottlenecks. Traveling across Africa is not easy (it took me 28H from Nairobi to Casablanca), there are language barierers separating the continent into different linguistic regions (French, English, Portuguese being the main ones). And just the fact that all too often we do not look to Africa for solutions. AMLD Africa is solving all that, by bringing everybody together for a few days in one of the best environments I got to experience. Thank you AMLD Africa.

GenZ: The Fiscally Aware Generation 6738

Tariq, 2 y.
I am sitting at Paul's cafe at the airport en route to Nairobi via Cairo for Applied Machine Learning Days (AMLD) Africa (a wonderful conference, more on that later). **In front of me 4 young males, early 20s, they speak loudly in french as they eat the burgers and fries they bought at another restaurant.** They talk about money. "You have no idea how much money I lose to taxes", says one of them. "40 to 50%! It's a lot of money, I would make so much more without it". He sees taxes not as a net necessary good, as most have been trained to see it, but as any other cost. Interesting, that's not the type of conversations you would expect from someone that young. It's not the first time I hear this type of conversation from GenZs. Why are GenZs becoming more fiscally aware than previous generations? I think it comes down to two factors: - Inflation - The entrepreneurial culture Inflation has hit everybody, for obvious reasons. However one constant with inflation is that it hits the poorest hardest. Young people tend to have less money. But that's not enough to raise awareness about a subject that most consider beyond boring. This brings us to the next point: *The entrepreneurial culture*. As a millennial I witnessed it's burgeoning and blossoming. It started timidly with a few books and blogs, then massive blogs, then best sellers, then YouTube videos and finally podcasts. Not so long ago being an entrepreneur was considered an unwise life choice. Successful people go to work for established companies. Such was common wisdom. However, as the 2008 recession hit and people started to look for more revenue streams, they also discovered the concept that having one's business can also mean more freedom and better financial security. There is however a big difference between the Millennial Entrepreneur and the GenZ Entrepreneur. The Millennial was still uneasy with the idea of making money and as such would speak about *"making a positive impact in the world"*, the GenZ is not burden in this way. You can see the shift in YouTube ads, today it's all bout how much you will make if you buy this or that business course. So whatever online business they start, being it drop shipping or whatever, they tend do it in a money aware way. Starting an online business is a hard, the competition is fierce. Naturally, they try to invest their hard earned money wisely. When the tax bill comes, they see it as it is: an unexpected cost that does not necessarily translate to a better life quality. Nothing is free in this incarnation. Some are not even shy about relocating to fiscally advantageous locations like Dubai and making videos about it. This could be the end of the blissful fiscally unaware generations.

Understanding the Complex Adoption Behavior of Augmented Reality in Education Based on Complexity Theory: a Fuzzy Set Qualitative Comparative Analysis (fsQCA) 6080

Augmented reality (AR) is one of the recent technological innovations that will shape the future of the education sector. However, it remains unknown how AR potential may impact the behavioral intention (BI) of using AR in education. Based on the Unified Theory of Acceptance and Use of Technology (UTAUT) and the technology acceptance model (TAM), this article empirically considers how such features impact user behavior. Utilizing survey data of 100 students, we perform fuzzy set qualitative comparative analyses (fsQCA) to derive patterns of factors that influence BI to use AR in education. The outcomes of the fsQCA demonstrate that high BI to use AR in education is achievable in many different ways.The current paper argues that students' BI to use AR in education is triggered by a combination of different aspects present in these supports. In order to address the factors that enable AR usage intentions in education, the paper presents a conceptual model, relying primarily on the UTAUT and TAM theories. This study investigated how these two theories shape intentions to use AR in education. The findings of the fsQCA analyses demonstrate the existence of multiple solutions to influence users' BI to adopt AR in education. The outcomes underline the significance of targeting certain combinations of factors to enhance student engagement. The most major limitation was the issue of causal ambiguity. Even though we employed the fsQCA as an adequate methodological tool for analyzing causal complexity, we could not justify causality. Furthermore, other methods can be used in future studies to obtain more detailed results.

whey protein 6407

Part 1 Whey protein has been widely used in untrained subjects [1] or in power trained athletes to increase muscle mass and to improve strength and physical performance [2-4]. However, there are relatively few studies examining the effects of whey protein supplementation on body composition and performance in well-trained endurance athletes [5, 6] and the results are sometimes conflicting. For example, Huang et al. [5] reported increased distance run in 12-min running test associated with an increase in whole body muscle mass, with no difference in performance in the placebo group; they also found decreases in “liver” enzymes, LDH, and creatine kinase (muscle damage markers) after 5-weeks of 33.5 g/day whey protein supplementation in endurance track runners. However, Roberson et al. [6] found increased lean mass, a tendency of mitochondrial capacity to be improved, but without significant improvement in physical performance after the ingestion of 25 g whey protein (post-exercise and pre-sleep) during 10 weeks in endurance runners. The inconsistent results of the effects of whey protein supplementation on endurance exercise performance and the associated post-exercise recovery parameters are in part related to some methodological differences such as the duration of supplementation, the amount, type, and timing of protein intake, and the training status of the subject. According to Phillips & van Loon [7], endurance athletes need more protein than the current recommendation of 0.8 g/kg/day for normal subjects, in order to achieve training adaptations and improve performance [7, 8]. The position statement of the International Society of Sports Nutrition (ISSN) stated that protein supplementation may help to offset muscle damage during and following exercise and promote muscle recovery in athletes [9]. The rationale for the increased protein intake for endurance athletes is that their training volume is typically greater than for powerful athletes, i.e. about 6 days per week so as to attain adequate training distance per week. Further, endurance athletes often use a mixed training approach incorporating eccentric exercises, plyometrics and obstacle courses; these training regimens often induce muscle catabolism as well as resulting in muscle damage [10, 11]. Muscle protein catabolism during exercise is not desirable as the amino acids lost in this process are required to support post-exercise and training adaptations. Also, excessive muscle damage with associated inflammation and requirement for muscle repair slows muscle recovery and impairs subsequent performance [12].

The 19th edition of Athletics World Indoors in Glasgow presentation... 6071

A few days before the World Indoor Athletics Championships, EME News, a specialized agency, presented the competition with the main protagonists athletes, event by event. Obviously the favorites are the athletes who dominated the winter season but obviously there will be surprise grabs like every edition. Having been present at numerous editions of these championships, myself, believe me it is well worth the detour. The championships are scheduled for March 1 and 2, 2024...two days of intense competition. Here is the full text as published by EME News. +++++++++++++++++++++++++++ The 19th edition of World Indoors will be for first time in Glasgow, but for third in the UK. Despite beeing it an Olympic Year several stars of the sport will participate (Lyles, Duplantis, Holloway, Bol, Warholm). It is the equaled earliest date in the history of the event, also 2018 Birmingham edition was held on March 1-4. In total 651 athletes (331 women and 320 men) are entered slightly less than in Belgrade 2022 (680, 372 men and 308 women). Now it is 133 countries, two years ago it was 137. Record numbers are 705 athletes at World Indoors 1997 in Paris (but without technical events direct finals) and 171 countries at World Indoors 2012 in Istanbul. In total 13 reigning individual world champions and seven individual gold medallists from the Tokyo Olympics are among the entries. From Belgrade 2022 title defenders only missing are two men Marcell Jacobs (60 m), Damian Warner (heptathlon), but also 6 women Mujinga Kambundji (60 m), Shaunae Miller-Uibo (400 m), Ajee Wilson (800 m), Ivana Vuleta (long jump), Yulimar Rojas (triple jump) and Auriol Dongmo (shot put). Gudaf Tsegay who won the 1500 m two years ago runs the 3000 m this time. Not invited as in Belgrade Russian and Belarus athletes, all technical events are held as finals. Evenings sessions on Saturday and Sunday are practically sold out. New Mondo track was installed, legendary David Rudisha is the ambassador. There’s good prize money, too, for places 1-6: $40 000-20 000-10 000-8000-6000-4000, plus a $50,000 bonus for a world record. Event by event short previews Men 60 m: Will Coleman´s fast start be enough to beat Lyles? Blake and Omanyala for bronze. 400 m: Two questionmarks, what is the shape of Warholm and Richards, both coming without any racing experience this winter. Then it is very open. 800 m: This year fastest Tecuceanu and Crestan. Hoppel has its experience, Masalela was winning on the circuit and Garcia is the defender. 1500 m: Nader is unbeaten this eason, Kessler comes with fast time, Nordas is World medalist. And Ethiopians. 3000 m: This is the highlight. Nuguse vs Kerr is the talk, but Barega and Wale have better times. 60mH: Holloway against the clock, 60 indoor wins in a row. Big fight for other medals (Cunningham, Joseph, French, Simonelli, Szymanski). HJ: Woo ruled during the season, Kerr comes from Down Under. PV: Mondo in his own World, can he produce again a global mark at championships? Obiena vs Nilsen and Kendricks for the remainder of the podium. LJ: Tentoglou by all books. Furlani ready for surprise. TJ: Zango should manage, then wide open. SP: Crouser question is how far. Fabbri, Walsh, Campbell for silver and bronze. Romani only one competition. Hep: Ehammer gave this priority over long jump, Skotheim the other contender, Mullings did not compete since end of January. 4x400 m: US always strong, but remember what happened in Belgrade. Belgium, Netherlands and Czech with current quality there. Women 60 m: Alfred vs Swoboda, top fight for gold. Hobbs and Dosso for bronze. 400 m: In case Femke and Lieke from the same coaching group will not be 1-2, we would say it was a surprise. 800 m: Alemu has the best time, but Reekie the spectators support. Or space for surprise name on top? 1500 m: This could be unique situation will full Ethiopian podium. 3000 m: Tsegay in her own class, Muir with crowd for silver, but Hull, St. Pierre, Meshesha not light opposition. 60mH: Charlton vs European force (Visser, Skrzyszowska). HJ: Mahuchikh vs Olyslagers, how high they can go? PV: Caudery, McCartney, Murto, Newman against US duo Moon and Morris. LJ: Davis looks like a clear choice, after her several contenders for two medals. TJ: 2 Cubans vs 2 US, and in between LaFond with Peleteiro. SP: Jackson vs Mitton for gold, is Schilder still in shape? Pen: Vicente should be the name, defender Vidts competed only individually this winter. 4x400 m: Netherlands followed by US followed by Jamaica or Poland or Britain. Czech dark horse.

Part 1 The 6th African Crosscountry Championships took place in Hammamet, Tunisia on Sunday February 25, 2024. Only 9 nations took part in these resumption championships after the interruption due to covid. If the number of participants was not significant, however, the quality was there with the participation of the great African and world cross-country nations. The golf course was simply extraordinarily beautiful. The number of natural obstacles and the variety of the course made this edition one of the best in African cross country if not the best one ever. Even the sometimes very strong wind could not prevent the athletes from giving their best, as demonstrated by the quality of the results. It must be said also, that the perfect organization of the Tunisian federation and the warm welcome, had a lot to do with this great success. xxxxxxxxxxxxxxxxxxxxx Individual results xxxxxxxxxxxxxxxxxxxxx 10 km Male BIP Name Nat.

Life is in the blood. 6625

EL MONO MAS GRANDE, 2 y.
Dark was the night. **Cold was the ground, and wet.** One stormy night, the biggest ape took refuge from the lashes of the rain beneath a magnificent oak tree. *"Magnificent"* thought the biggest ape as he gazed the upon the branches stretching far and wide. The night was cold, some cold drops still found their way to his back. But right here, sitting on the biggest root, the biggest ape was at peace. All he had to do is wait. Two men appeared from each side of the road. One from the east, the other form the west. "Can I join?", said the main from the east. "May I sit?", said the man from the west. *Yes*, nodded the biggest ape. The men sat. The man from the east opened a small wooden box revealing exquisitely made little figurines. He bowed down an started to pray. The other man took a book out of his bag. A red book with a shining blue sword on the cover. And started to read. When the first man had finished, the second one said: "I see you are religious man." - "I am, I see you do not believe in the gods." Answered he, pointing at the book. - "I do not. I believe in the power of reason. Man has no need for supersistitions." - "Reason is limited. How can you speak thus, have you never made a mistake in your life." - "Have your gods answered all your prayers." Both men remained silent as they looked at each other. - "What say you, ape?" Said the man from the east. Looking at the figurines in the man's box, he answered, his deep voice echoing the rumbles of the skies: *"They have eyes, yet they do not see. They have hands, yet they do not make. They have mouths yet do not speak."* Then turning towards the others man's book, he paused. *"Your sword has two edges, yet it does not cut."* *"Life is the blood"*, said the biggest as he was making his leave. *Life is in the blood.* Thus spake Apathustra.

The Impact of Big Five Personality Traits on Augmented Reality Acceptance Behavior: An Investigation in the Tourism Field 6411

Dr. EL Mostafa Bourhim, 2 y.
Along with the rapid development of the Internet and mobile devices, the integration of augmented reality (AR) in the tourism sector has become very popular. Utilizing the Big five model (BFM) as the theoretical framework, the study examines the role of personality in influencing the behavioral intention (BI) to use mobile augmented reality in the tourism sector (MART). The study further investigates the role of personal innovativeness (PIV) in determining tourists’ behavioral intentions to use MART. Quantitative research was carried out to test the conceptual model. This paper strengthened the analysis by implementing PLS-SEM method using data collected from 374 participants. The study results demonstrated that openness to experience (OPN) is a strong predictor of MART use. In addition, agreeableness (AGR), conscientiousness (CONs), extraversion (EX), neuroticism (NR), and personal innovativeness (PIV) have all significant and positive impacts on behavioral intention (BI) to use MART. The present research purpose was to investigate the BFM variables with regards to MART use. The research also examined the contribution of PIV in explaining the BI to use MART. By employing PLS-SEM to tackle the primary study question. The current work makes a significant advance in MART use research. Empirically, the findings achieved are consistent with the BFM. Based on the outcomes of this research, all relationships have been assessed as being statistically relevant. Moreover, PIV positively influences the use of MART. The BI to use MART was positively impacted by AGR (H1: β = 0.128), CON (H2: β = 0.108), EX (H3: β = 0.124), NR (H4: β = 0.322), and OPN (H5: β = 0.169). This implies that users are expected to exhibit a strong BI to use MART when they are agreeable, conscious, extroverted, neurotic, and open to experiences. Additionally, the outcomes of the present paper also significantly upheld the association between PIV and the BI to use MART. Path analysis was found to be significant and positive (H6: β = 0.156); the result states that innovative tourists will intend to use MART. The important limitations are a higher risk of overlooking ‘real’ correlations and sensitivity to the scaling of the descriptor variables.

Extended reality (XR) is becoming a growing technology used by athletes, trainers, and other sports professionals. Despite the rapid growth of XR, its application in sports remains largely unexplored. This study is designed to identify and prioritize factors affecting the implementation of XR in Moroccan sports science institutes. To achieve this, the study employs the A’WOT methodology, a hybrid multi-criteria decision method combining the Strengths, Weaknesses, Opportunities, and Threats (SWOT) technique with the Analytic Hierarchy Process (AHP). Through expert group discussions, the study identifies and categorizes the factors affecting XR implementation into SWOT groups. Subsequently, the AHP methodology is employed to determine the relative importance of each factor by conducting interviews with a panel of sports and XR experts. The study’s findings, obtained through the A’WOT methodology, establish a ranking of the fundamental factors for successful XR implementation in Moroccan sports science institutes. The findings suggested that a strategic approach for implementing XR technology in Morocco needs to be driven principally by a combined approach based on the SWOT opportunities and strengths groups. The present study investigates the benefits, challenges and opportunities of XR technology in Moroccan sports science institutes based on the SWOT-AHP framework. The strengths and opportunities ratings based on XR The Moroccan Association perspectives are positively inter-preferred for XR technology. Thus, based on this research, the framework provided can be interpreted as a roadmap for supporting the development of the strategic implementation of XR technology in Moroccan sport science institutes, while providing more credible information for decision-makers in the overall process. An in-depth analysis of the findings enables us to conclude that the strategic implementation of XR technology in Moroccan sports science institutes has to be driven principally by the opportunities factors that could assist in overcoming the identified main weaknesses and threats, along with maximizing the strengths. Following these guidelines, decision-makers are expected to initiate a range of activities in order to establish the right external environment in which opportunities can be fully exploited to tackle the principal weaknesses and threats revealed by the analysis. This research provides strong evidence for XR deployment in the sense that it reflects the views of XR The Moroccan Association practitioners and researchers on XR technology.

[Short Stories #3] Awaiting You 6718

Tima EL, 2 y.
Royal Gambit is an annual event organized by the Cogitaria realm to select its new king. The game involves a chess match between two participants: the candidate and the reigning king. The coveted prize is a tiger mask crown, symbolizing royal authority. The victor ascends to the throne as the new king, while the defeated succumbs to their demise. For over decades, the throne of Cogitaria has remained unchallenged, as fear of the perilous stakes in the Royal Gambit game dissuades potential contenders. Each year, the reigning king eagerly awaits a challenger, yet no brave soul steps forward to partake in the high-stakes game, leaving the kingdom in a prolonged state of suspense. However, amidst this prolonged era of unchallenged rule, an exception emerged during one of the annual Cogitaria festivals dedicated to selecting the new king through the Royal Gambit. A stranger, passing through the realm, caught wind of the festivities that had lingered for more than a week, awaiting a candidate brave enough to face the reigning monarch. Intrigued by the mysterious allure of the event, the stranger decided to step into the fray. As the chessboard opened after decades of dormancy, each piece took its rightful place, setting the stage for the Royal Gambit to commence. The chess pieces clicked and clacked, echoing the strategic dance that would ultimately decide the kingdom's destiny. With a masterful stroke, the stranger executed a climactic checkmate, the chess pieces freezing in place as the kingdom held its breath.

The Death of Liberalism: Nature and the Steppe 5973

Liberalism has failed. The liberal paradigm, which began during the Enlightenment, is collapsing. We are at the end of a great civilizational cycle. Another dark age is upon us. But out of this dark age will emerge afresh the doctrine of nature, and new barbarians to revitalize the West and direct it towards a new destiny. The fundamental failure of liberalism is that it does not address the problem of nature, and it moreover conceals it with the idea of natural rights, when no such thing exists. Failing to recognize the fundamental laws of nature and concealing them with idealistic human laws of convention is one of the most fatal errors a civilization can make, and may in fact be why all civilizations fall. The Greeks devoted much of their philosophy to the relationship between Physis, nature, and Nomos, law. Yet the idea of nature, the discovery of nature, is quite rare throughout human history. In Selective Breeding and the Birth of Philosophy, Costin Alamariu argues that the idea of nature emerges out of a “refinement, abstraction, or radicalization of the aristocratic way of life and of the principle that underlies aristocratic life and the aristocratic worldview.” He writes, “When the idea of nature merged, it did so in opposition to convention or ‘custom.’ Cows graze, wolves hunt by nature; but different tribes of people deal differently with the dead—cremation, burial, etc.—by custom or convention. It is a notion distinctly similar to our ‘nature versus nurture’ or ‘nature versus culture’ or ‘nature versus social construct.’ The question of what was ‘by nature’ or ‘by convention’ animated much of Greek intellectual life, and had important political meaning, for example, with the aristocratic party generally favoring the side of nature and the democratic party generally favoring the side of convention. In the first chapter I try to explain how a rudimentary idea of nature could have emerged out of the ‘primitive’ or ‘prehistoric’ mind, out of the mind as ruled exclusively by ancestral convention or custom.” He later continues, “The answer is that it could not. The moment us discovery of nature—which is the precondition of both philosophy and science—is the preserve of one very unusual people, the ancient Greeks, and, long thereafter, those parts of Europe where Hellenistic civilization was promoted, first by Rome, and later in a considerably modified form in Christianity and various Christian states that had inherited some of the roman institutions.” The idea of nature emerged in the late stages of Athenian aristocracy, as a response to the aristocracies many critics; as a solidification and abstraction of the aristocratic worldview. But we then must ask the origins of the aristocratic worldview. As we have talked about at length on this channel, the first aristocracies were formed out of nomadic, pastoralist peoples conquering sedentary farmer populations and imposing their hierarchies and worldview upon them. This means that the aristocratic worldview, and the first seeds of the idea of nature, was born among pastoralists peoples. The sedentary, tribal life of the farmer is ruled by convention and custom, and he is therefore unable to separate what behaviors he has inherited through custom or religion and which through biology and nature. However, a nomadic people would have been able to observe a great many peoples and their differing way of life, allowing them to see the behaviors which remain consistent across the species and formulate a rudimentary idea of ‘human nature.’ Further, the harsh conditions of the nomadic way of life, which relied on the breeding of strong herds, and later, the domestication and breeding of horses, would have made ideas of heredity and breeding, of nature and biology, especially important. Darwin’s natural selection would have been self-evident: only the strong—the fittest specimens—survive the harsh life on the steppe. And sexual selection would have been just as evident: if the fittest specimens are bred, they will improve the quality of the herd over time and even lead to behavior alterations, like the domestication of horses.

People have always aspired to freedom and prosperity. They always wanted to live from their work. Their pleasure is to see their offspring play, learn and prosper. People have always wanted peace as a way of life. Living in peace…a whole concept, a chimera. Alas It has never been completely like this. Except for brief, precious and rare moments that history could not remember. These moments remain exceptional, they were brief, even ephemeral. People have always sought to not be exploited by anyone, all the while they tend to exploit others. Sometimes, unfortunately, by dehumanizing with immeasurable cruelty. A history of exploitation while giving yourself a clear conscience. In fact, peoples are groups of humans with common traits. People are formed over time and coalesce around common interests. To defend himself and his interests, man can only live in community among a people. Man aspires to freedom and peace; humans say they have values but humanity does not care. The course of history unfortunately demonstrates this. Humanity imagined a way to aspire to this freedom to live in harmony: Involve everyone in the decision and give man the impression that he is part of his destiny. Nothing better than a word with Greek etymology to make it serious and credible: Democracy. This sounds very good. Yes, Democracy is there in principle to free us and make our voices heard. To realize our desires and respond to our need to live in peace. To live together. To respect others in their human dimension. To limit ourselves to our rights without encroaching on those of others. Democracy is a sort of safeguard for each and every one. At least that is how it was perhaps imagined and designed. It allows us, in theory, to express ourselves, defend and assert our rights from the most basic to the most sophisticated. Democracy is sold to us as the one and only model for the prosperity of people and their moral and material well-being. Now democracy is playing a dirty trick on us: handing over with tied hands the most mediocre among us, the most ferocious, the hungriest, the most bloodthirsty; to those who rejoice when graves are dug, when blood flows, when a child cries or a woman cries. Downside... I was born in a moment of peace, one of the few, just a few years after a cruel war started by Europeans. At the beginning they killed each other. They will then involve poor Africans as cannon fodder. Absolute cruelty for years. Millions of innocent people thrown underground. The break will be short. Without wasting time, humanity will experience the Korean War, that of Vietnam, that of Iraq, that of the Falklands, lots of squabbles in Africa and so on...The instigators and authors are always the same. Each time it's good versus evil...Each time democracy is involved, rightly or wrongly. The democratic world against the other...A democratic world which defines itself in absolute, total, integral contentment, with double standards as the only alternative of "reasoning" and "judgment" too; eliminating all others from the good square at will. Each time, genocide, each time cruelty, each time dehumanization. Each time faced with the helplessness of the man who only wants to live in peace. As for whether humanity ever existed. Will it exist one day... You understand, I don't want to talk about Palestine, the wound is still fresh and the criminals are still alive. Aziz Daouda

Style is the man 6531

The particular imprint of exceptional humans has marked history, if not made history. Georges-Louis Leclerc de Buffon, French naturalist and mathematician and member of the Académie Française, undoubtedly marked by the rigor of the exact sciences, stated in his reception speech: ‘Style is the man himself’. Even if Buffon only spoke of literature and science, style thus becomes an objective constant of each of those who mark history with a particular legacy. Foreshadowing what the Crown Prince would grow to be when King, the late His Majesty Hassan II of Morocco will take up the notion of style, precisely quoting Buffon. He said in a notorious interview : ‘Style is the man’. No one wanted to announce that the reign of His Majesty King Mohammed VI of Morocco was going to be different from his own, although in the logical continuity of history. Today the trend is to confuse style with a more modern notion of ephemerality: the look. If the look, which will summarize an outfit, a haircut, colors, is circumstantial and therefore contingent on the moment, style is a constant of the person and accompanies him throughout his life. Style will experience an evolution but in a logical continuum. If style ends up being validated and confirmed by history’s objective appreciation, the look is not necessarily in symbiosis with style. The look is tainted by subjectivity. It depends on each person’s perception, image and imagination. It is marked by the appreciation we have of the person we meet in a particular circumstance, a particular environment. The look is a subjective composition which can be modeled simply through a photograph which falls into your hands, a video viewed on a train or on a plane, so many images that forcefully invite themselves into the intimacy of the onlooker by forcing the screen from a phone or a tablet, through advertisements and social media. The look can go so far as to contrast with the style. It is the subjective assessment that we make of the person being scrutinized; and will be even more biased if it is accompanied by a comment even if it is the antipode of objectivity. A film actor can thus be stuck by his look and his acting, the personality traits of a character, when all he has done is succeed in restoring them to us for the duration of a film. The look is appreciated as long as it coincides with the image we have of the person at the very moment of meeting. It depends on the success of the approach and the reaction of the person encountered. It is conditioned by the circumstances of this encounter, the degree of surprise and the emotional level it arouses. The first glance will be decisive here. The look generates admiration: everyone will form an idea of the person they meet based on their own appreciation, their emotions and their state of mind at the moment. The degree of sympathy expressed or shared can thus lead to idolatry. The style commands respect and generates love and appreciation. It is a constant that evolves slowly, surely, and becomes significant. It is assessed on rather objective and verified criteria. Style is indelible and is linked to action through art and manner. Style leaves a mark forever. It is this imprint that allows us to judge and define its contours. History is judge of style. Aziz Daouda
