triggered

If Ukraine promoted the use of drones, Iran has triggered the Terminator algorithm. And that was already a problem in science fiction

by

In the gulf war 1991, the international coalition took more than a month to launch some 100,000 airstrikes after weeks of planning. Three decades later, the ability to process military information has changed radically: satellites, sensors and drones generate amounts of data that no human team could analyze alone. In this new technological environment, the true battlefield is no longer just the air or the land, but the speed at which information is interpreted. From the drone to the algorithm. Recent wars had already anticipated a profound transformation of modern combat, but the conflict with Iran seems to have crossed a different technological frontier. If the war in ukraine popularized the massive use of drones as a dominant tool from the battlefield, the campaign against Iran has introduced a logical even more radical: integration artificial intelligence at the very heart of military decisions. In fact, the initial attacks showed an intensity difficult to imagine just a few years ago, with hundreds of targets hit in a matter of hours and thousands in a few days. That speed was not only the result of greater firepower, but also of the use of capable systems of analyzing enormous volumes of data and transforming that information into almost instantaneous attack plans. Understanding the “kill chain”. I remembered this morning the financial times that traditional war, the so-called chain of destruction (from identifying a target to launching the attack) was a long and bureaucratic process. Intelligence officers analyzed information, wrote reports, commanders evaluated options and finally the coup was authorized. A process that could take hours or even days. The incorporation of AI is reducing that cycle drastically. We are talking about platforms that integrate data from satellites, drones, sensors and intercepted communications that are capable of generating lists of targets, prioritizing them and suggesting the appropriate weapon in a matter of seconds. The result is extreme and disturbing compression of the kill chain: What once required prolonged deliberation now becomes an almost instantaneous sequence. The digital brain of the battlefield. Behind this acceleration are data analysis systems that act as a true operational “brain.” These platforms combine geospatial intelligence, machine learning and advanced language models to interpret information and propose military actions. Its most disruptive capacity is that it no longer only summarizes data, but can reason step by stepevaluate alternatives and generate tactical recommendations. This allows military commanders to process volumes of information that are impossible to handle manually and multiply the number of operational decisions made in the same period of time. In practice, algorithms are allowing select and execute objectives at a scale and speed that were previously unthinkable. Bomb faster than thought. The result of this transformation is a war that begins to move at a rapid speed. higher than human pace. Artificial intelligence can now analyze information, detect patterns and propose attacks faster than a team of analysts could even formulate the right questions. Some experts describe This phenomenon as a form of “compressed decision,” in which planning is reduced to such short windows of time that human managers can barely review what the machine has already processed. In this context, another disturbing idea: that destruction can precede the human reflection process itself, that is, first comes the recommendation generated by the algorithm and then the formal approval of the person who must execute it. And there, there is no doubt, we can have a problem of colossal dimensions. The human dilemma in algorithmic warfare. Because this technological acceleration is generating a growing debate about the real role of humans in military decision-making. Although the armed forces they insist As final control remains in the hands of people, the time available to evaluate system recommendations is increasingly reduced. Some analysts fear that this will lead to a form of “cognitive download”one in which military leaders end up automatically trusting the decisions generated by algorithms. Other countries like China itself observe this evolution with concern and warn of the risk that automated systems end up directly influencing life or death decisions on the battlefield, associating the scenario with the closest thing to the “Terminator algorithm” due to the unequivocal way in which all paths approach James Cameron’s fantastic proposal. A new accelerated war. If you will also, what is emerging is not just a new military technology, but rather a new time of the war. AI makes it possible to process information on a massive scale, identify targets more quickly, and execute attacks with unprecedented simultaneity. This means that military campaigns can develop at a pace that overflows the models traditional planning. From this perspective, war no longer advances solely at the pace of logistics or firepower, but at the pace of algorithms capable of interpreting the battlefield in real time. And in this unprecedented scenario, strategic advantage could increasingly depend on who is able to think (or calculate) faster than the adversary. Although neither of them be human.

The United Kingdom has always been a country of pets, but fear has triggered a dangerous demand: dogs ready to attack

by

The proverb says that the dog is man’s best friend. In United Kingdom more and more people He believes he can be something more: his best protector. At least that is the feeling conveyed by dog ​​training companies, which have found a curious increase in demand thanks to the visibility that networks and networks are giving them. celebrities. They are not cheap, they carry many more responsibilities than a ‘conventional’ pet and they operate within a complex legal framework, but that does not prevent the fact that on the other side of the English Channel it is increasingly easier to come across dogs ready to jump at the command of their owners. There are those who prediction even that personal defense dogs are a billion-dollar market that is rapidly expanding in the United Kingdom. What has happened? That the training of defense dogs is becoming an increasingly profitable business in the United Kingdom. We know it thanks to Guardianwhich a few days ago published an extensive report in which he explains that this type of pets, ready to obey the orders of their owners and defend them with hooves and teeth (in the most literal sense of the expression) if necessary, is experiencing considerable growth. There are not many statistics or official data that corroborate the trend (Guardian does not provide them at least), but of course the message from the sector is clear. “Demand has increased, without a doubt,” confirms Alaster Bly, founder of K9 Guarda company specializing in “highly trained security guard dogs.” There are even trainers who offer special courses to train pets that people already have in their homes. Has demand increased that much? A quick search Google shows a good number of British companies and blogs dedicated to the same thing: selling or informing about defense dogs. And that’s not the only clue. There are even market reports that assure that it is a business in full expansion. A recent study published by AdAstra Solution estimated the size of the British protection dog market at 1.2 billion dollars in 2024. Its forecast is that in just a decade it will rise to 2.5 billion, with a growth rate CAGR of 9.2%. The key is not only that these pets arouse more interest, but that they are expanding their demand base. What does that mean? That dogs trained to serve as bodyguards seem to be ‘becoming popular’ in the United Kingdom. They are far from being a mass phenomenon, but something has changed: they are no longer a ‘whim’ of the wealthiest families or professionals in the security field. According to confirm Guardian After interviewing professionals in the sector, the panorama is changing little by little, as demand increases. Bly acknowledges that the majority of his clients are still wealthy people, but he has also seen growing interest from families who are not wealthy and simply want to “invest in security.” The reasons for this change? There are two that seem key. The first is concern about crime. Although official statistics can be contradictoryStatista tables reflect that the number of violent crimes against people recorded by the police in England and Wales have increased in recent decades. And clearly. In fact, although they have decreased in recent years, they continue to remain well above the snow levels of the beginning of the 21st century. Are there more reasons? Yes. The networks. British reporter Elle Hunt remember that the increase in demand has gone hand in hand with greater media exposure of this type of dogs through various means. One is celebrities. In recent years, personalities such as Rochelle and Marvin Humes, Molly-Mae Hague, Katie Price, J.Terry…actors, singers, footballers and television personalities with well-identifiable faces in the United Kingdom. In the sector, there are those who remember that the increase in demand coincides with greater visibility through Instagram or TikTok of defense dog exhibitions and competitions. Schuzthunda canine agility sport. And how much do they cost? Much more than a ‘conventional’ dog. A trained dog requires considerable work that, sometimes, begins even before the dog is born. Bly works, for example, with hybrids of German and Belgian shepherds, a “very specific genetic mix” that allows it to adapt to its function. Hence they are not cheap. They cost (at least) £32,000. However, price is only one of the factors that the owner must take into account. ¿Is there anything else? Yes. Another factor, even more important, is the care and responsibility that comes with having a dog specially trained for defense. Guardian remember that these personal protection dogs have a complex legal framework, since they are not under the Guard Dogs Law, which does regulate animals in charge of protecting premises or professionals. “They receive the same treatment as any other dog,” explains a criminal lawyer. The problem is that standard home insurance policies can leave them out of your coverage. An important factor in a country that has seen how in recent years attacks increased of dogs recorded by the police.

While industrial production collapses in the European Union, in Switzerland is triggered. And it is an energy issue

by

In the midst of the European energy storm, Switzerland seems to live in a bubble of prosperity. In a recent publicationthe geopolitical analyst Velina Tchakarova showed how the Swiss industry continues to grow in front of the European Union. And the data does not deceive anyone: in the first quarter of this year the industrial production of the Helvetic increased 8.5% year -on -yearwhile in Germany recorded last June A 1.9%collapse, the worst data in years. The contrast is even more evident in the long term: since 2011, Swiss industrial production It has grown almost 40%in front of the German stagnation. The Swiss road. True to its neutrality, but knowing how to position itself, the Swiss industry is dominated by sectors of high added value and low relative energy consumption, like pharmaceuticals and biotechnology. But here is the most revealing: that low energy consumption is not only efficiency, but also outsourcing (a sophisticated strategy of Green offshoring). An EBP consultant study for the Federal Environmental Office (BAFU) shows that two thirds of the environmental footprint of Switzerland They are generated outside their borders. The report Umwelt Schweiz 2022 Confirm this pattern: the country reduces its internal impact at the expense of moving it abroad. There are different examples that illustrate it well: the Roche company announced in May A new biopharmaceutical plant in Shanghai, the Lonza company operating in Guangzhou Or, the most striking case, Siegfried managing a global network with headquarters in different countries that allows you to distribute phases of the chain outside the Helvetic territory. Together, these movements illustrate how the Swiss industrial “miracle” retains the added value at home while displacing the most polluting and expensive part abroad. To this is added an electrical system less vulnerable to gas: the Hydroelectricity and the nuclear They represent a good part of their mix. The Labyrinth of the EU. At this time you are going through an industrial decline: Eurostat reported that in June the production fell 1.0% in the EU as a whole and 1.3% in the eurozone. The setback It was coming last yearwhen the manufacturing volume was 2% lower than in 2022. And Ing Think analysts They warn that European industrial production It remains 5% below two years ago, a prolonged stagnation signal. To this fall is added a perfect storm: high energy costsCO₂ and an internal debate about its energy model. France, With a reactor -based systemleads the block that defends nuclear energy as a backbone of the transition. Spain and Portugal, with solar and wind abundance, demand otherwise: more interconnections and networks To take advantage of renewable surplus. In addition, it is added The tireless search by the EU of looking for another output to stock up that it is not Russia in terms of gas. While Switzerland transfers its heaviest loads to Asia, Europe is enclosed in its own rules, paying CO₂ rights that further increase its energy intensive industries. Switzerland outsourizes, Europe internalizes. Switzerland harvest added value, Europe assumes added costs. The awkward contrast. Here the paradox emerges. Switzerland exhibits an expansion industry, favorable environmental statistics and a more stable electricity supply. Everything seems to indicate that it has found the perfect formula to prosper in the midst of European chaos. For its part, the European Union is paying the price If pioneer: its factories face much higher energy costs, their energy intensive industries lose competitiveness and their governments carry the pressure of meet strict climatic objectives. But Swiss success relies on a small print. The report itself Umwelt Schweiz 2022 He admits that two thirds of the country’s environmental footprint are generated outside their borders. That is, Switzerland retains at home the added value of its pharmaceutical and technological industry, while the energy cost and pollution are transferred to other places. That apparently virtuous model implies a strategic risk: to depend on global supply chains and expose themselves to political vulnerabilities in Asia. In climatic terms, the question is inevitable: are global emissions really reduced when Switzerland “is cleaned” at the cost of others getting more? Or, in other words, isn’t its industrial miracle with another way to outsource the environmental invoice? Forecasts On paper, Switzerland seems greener and more prosperous. But the true story is told in the chimneys of China and in the closed factories of Germany. The Helvetic miracle works, to a large extent, because the energy and climatic invoice is paid by others. While industrial production collapses in the European Union, in Switzerland is triggered. However, that balance, sustained in global chains and in others, could be broken when geopolitics tightens. The real unknown is not how much the Swiss miracle can last, but who is willing to pay his invoice.

Russia’s order has triggered anxiety in Europe. Germany and France are already preparing for the worst: 1,000 injured per day

by

To the incursions of Russia in the European airspace that took place last week In Poland, Romania and Estoniaanother in Denmark has joined with chaotic consequences for airlines. NATO has raised the voice while Moscow seems to test the allied cohesion in the Baltic. In the background: a series of movements that indicate two things: anxiety has shot in Europe, and some begin to prepare for a war scenario. Denmark does not give credit. Denmark has described As an “unprecedented attack” the incursions of drones that have forced to close the airports of Copenhagen and Oslo for hours, leaving tens of thousands of stranded passengers, in an episode that encompasses the wave of aerial rapes and drones attacks in past days To Poland, Romania and Estonia. The aircraft appeared from multiple directions, alternating lights and then disappearing, and the Danish authorities attribute them to “a capable operator”, while the Kremlin denies it. Prime Minister Mette Frederiksen He talked about The “more serious” aggression against a critical infrastructure of Denmark and did not rule out any hypotheses, opinion supported by leaders such as Ukrainian President Zelenski and by EU spokesmen, who see a pattern of reckless actions by Russia. NATO celebrated meetings Under article 4condemned the violations and stressed that Rwill effort capabilities and deterrenceand some officials already contemplate the possibility of more forceful responses (even demolition) if these provocations are repeated. France and preparations. In France, the controversy has exploded after a Publication of Le Canard Enchaînéwhich revealed a letter sent in July by the Minister of Health, Catherine Vautrin, in which she asked French health agencies to prepare for a possible “major commitment” In March 2026. The document urged hospitals to be ready to serve several thousand soldiers during periods that could extend 10 to 180 dayswhich included both French and foreign troops. The news, despite proceeding from a satirical environment, generated accusations that Emmanuel Macron would be secretly planning the country to the war against Russia. The extreme right, represented by the Eurodiputa Thierry Mariani, It went further suggesting that a conflict would allow to suspend the presidential elections of 2027. The official clarification. The Ministry of Health He did not deny authenticity of the letter, but he clarified his goal: it was a Preventive Planning Faced with possible risks and threats that could affect the hospital system, including the arrival of a large number of victims of an international conflict. The measure, according to the Ministerial Crisis Center, sought to guarantee the capacity of the civil health system to absorb a massive flow of military patients in case France, as a member of NATO and ally of Ukraine, was indirectly involved in a war set. It was not, therefore, a war plan per sebut an exercise in advance of contingencies. Germany and preparations. It happens that Germany It has begun To explicitly plan how to face an eventual large -scale conflict between NATO and Russia, the scene that many alliance analysts place Around 2029. Reuters explained That the calculation that marks this preparation is as sober as disturbing: up to 1,000 soldiers Germans wounded per day may require medical care in case of an open confrontation, a figure that the inspector general of Health, Ralf Hoffmann, qualifies as realistic based on the intensity of the fighting and the units involved. Ukraine lessons. The war in Ukraine has radically changed the nature of the injuries. If the bullet wounds predominated before, today the panorama is dominated by the devastating drones effectsMERODERE AND EXPLOSIVE MORMERS, which generate amputations, burns and multiple trauma. Hoffmann Underline That the “death corridor” of ten kilometers on each side of the Ukrainian front, plagued by hostile UAVs, shows how immediate medical evacuations have become almost impossible: injured should often be stabilized for hours under constant fire before being able to be transferred. How to evacuate. With this horizon, Berlin is studying Expand your abilities of flexible medical transport, inspired by the Ukrainian experience with hospital trains. It is considered to incorporate trains, buses and a greater number of sanitary aircraft, with the aim of guaranteeing staggered evacuations: initial attention in the front, intermediate stabilization and final transfer to hospitals within the German territory. This medical logistics chain demands a robust, decentralized and capable system under air and electronic threat. The plan contemplates that the injured receive definitive care especially in civil hospitals, with an estimated volume of 15,000 reserved beds within a national total capacity of 440,000. The coordination between the military medical service and the civil health system will be essential, and the medical body of the Armed Forces, currently 15,000 troops, must be extended significantly to face the magnitude of the challenge. The Kremlin and article 5. Explained the Financial Times That all this climate of extreme anxiety in Europe possibly responds to a Moscow tactic: to demonstrate that the NATO collective defense clause, Article 5it lacks real value. A hesitant response to a provocation could open the door to Russia trying to “break down” small European states without facing the block as a whole. Scenarios such as a land incursion under the pretext of protecting Russian minorities in Baltic countries are part of the recurring fears of military planners. To do this, Moscow has uncertainty that surrounds Washingtonwhose contribution represents about 40 % of the military capacities of the Alliance in Europe. The unknowns Trump. The American factor is decisive. With units of Himars Artillery And tanks already deployed in the Baltic, the military presence is significant, but the key question is what Donald Trump would do in case of open aggression. Distrust is mutual: in Washington some see the Baltic as excessively ideological and aggressive against Moscow, while in Tallin the vote of the United States is remembered with Russia in the UN as An alert signal. The president’s volatility adds an unpredictable element: as well as surprising authorizing Attacks to IranI could react unexpectedly in a crisis in Eastern Europe. Between fear and dependence.

Uranium centrifuges have triggered war between Israel and Iran. Without them it is impossible to have the atomic bomb

by

Uranium centrifugers monopolize a good part of global attention since it began The last episode of the conflict between Israel and Iran on June 13. The government led by Benjamín Netanyahu has set as a fundamental objective dismantle the Iranian nuclear program that presumably seeks to develop the necessary technology to Manufacture atomic bombs. And to achieve it Israel and the US have bombarded The facilities in which Iran was carrying out the enrichment of uranium, such as the plants of Fordo, Isfahán and Natanz. According to Israel and the US, these Iranian nuclear facilities housed several hundred uranium centrifugers. It can even that several thousand of these machines. Its role in the nuclear program not only of Iran, but in that of any country with the ability to manufacture nuclear weapons, is to enrich 90%uranium. Otherwise it is not possible to use it to produce atomic fission pumps o Thermonuclear devices that combine fission and nuclear fusion. However, in these last pumps uranium is only used in the fission stage, which acts as a detonator of the nuclear fusion. In this last reaction two isotopes of hydrogen intervene: the deuterium and the tritium. Uranium-235 is the true protagonist of this story To precisely understand what is the purpose of uranium centrifuges it is necessary that we previously investigate in two isotopes of this chemical element Metallic, heavy and radioactive. Uranium is present in nature in very low concentrations, normally in rocks, land and water. Hence, its obtaining is expensive and its complex treatment, since it requires chemical processes capable of separating it from the other elements and impurities with which it usually lives. It has 92 protons and many other electrons orbiting around the nucleus, and the latter incorporates, in addition to the protons, between 142 and 146 neutrons. It is important that we remember that the nucleus of an atom is usually constituted by a certain number of protons and neutrons (although not always: the protio, the isotope of the most abundant hydrogen, has a single proton and no neutron in its nucleus), as well as by some electrons that orbit around it. The fact that the number of neutrons of the uranium nucleus may varyas we have just seen, it indicates that there are several isotopes of this chemical element, which are nothing other than atoms with the same number of protons and electrons, but different number of neutrons. In fission reactors and nuclear weapons it is used as uranium-235 fuel The reason why in the fission reactors and nuclear weapons is used as an uranium-235 fuel, and not another isotope of this element or any other chemical element, it consists that by bombarding its nucleus with a neutron (a process that is known as induced fission) the uranium-235 is transformed into uranium-236, which is a more unstable element. This simply means that Uranium-236 cannot remain long in its current state, so it is divided into two nuclei, one from Bario-144 and another of Crypton-89, and also emits two or three neutrons. And here comes the really interesting: the sum of the masses of the Bario-144 and Crypton-89 nuclei is slightly lower than the Uranium-236 nucleus from which they come (“disappears” around 0.1% of the original mass). Where has the mass we lack? Only one can be left: has been transformed into energy. Formula e = m c²probably the most popular in the history of physics, relates mass and energy, and what it says is simply that a certain amount of mass equals a specific amount of energy, even if the dough is at rest. In fact, the equivalence between mass and energy, proposed by Albert Einstein In 1905, he tells us something more important. The C of the formula represents the speed of light in a vacuum, which, as we all intuit, is a very large number (299,792,458 m/s). In addition, it is squared, which means that even a very, very small mass, such as the portion of the nucleus of an atom, although it is at rest contains a large amount of energy. This is what we know as resting energy. If the mass is in motion its total energy is greater than its resting energy. And, if we observe the equivalence between mass and energy, it is easy to realize that the mass of a body in motion too is greater than its resting massa phenomenon that It introduces us fully into relativistic physics. In any case, the energy we obtain by merging or fissting atomic nuclei comes from the force that keeps them together: Strong nuclear interaction. Understanding with some precision the relationship between mass and energy is important because it helps us understand how it is possible that a mass as small as that of an atom allows us to obtain such a large amount of energy. In any case, the nuclear fission process does not end here. And it is that each of the neutrons that we have obtained as a result of the disintegration of the Uranium-236 nucleus in the Bario-144 and Crypton-89 nuclei can interact with other physically nuclei, causing a chain reaction. However, not all neutrons emitted during the disintegration of the Uranium-236 nucleus will interact with a physirable nucleus. But they don’t need to do it all. It is enough that only one of those neutrons achieves it to obtain a stable number of fissures, and, therefore, a controlled reaction, which is the objective of the reactors of the nuclear power plants. Centrifugators serve to increase uranium-235 concentration The most abundant uranium isotope in nature is uranium-238. In fact, it represents approximately 99.3% of the total uranium. The problem is that this isotope is not physically. The uranium enrichment process seeks to increase the proportion of uranium-235, which, as we have seen, is physically, within the total mass of uranium. However, this last isotope is very scarce in nature. So much that only represents 0.7% of natural uranium. The nuclear reactors of the power plants require … Read more

With the electric consumption triggered by the air conditioning, Singapore has had an idea: buildings that “sweat”

by

Fresh news: it’s hot. A lotand it doesn’t look like This summer is going to give us a break. Bet on Fans or by him air-conditioning It is a solution, but there is a problem: temperatures will continue to increase and Electricity consumed by air conditioning devices It is a problem. Urgently Find passive solutionsand Singapore may have found the key thanks to a new painting. Your secret? Makes buildings “sweat.” Short. In 2022, air conditioning represented 7% of world electricity consumption. The estimate It is that, by 2050, that electrical consumption triggers up to 20%. In order to cool buildings, there are already researchers who are experiencing with heat dissipation solutions to create fresher environments without the need for air conditioning, such as The nanomaterials or a Botijo ​​technology nut rotation. Although we are seeing how to make the air conditioners are more efficient. But there is an easier solution that could be applied to already built buildings: a layer of paint. The Insulating paint It already exists, with examples Like the ultrabrabas developed by the University of Purdue that reflects Up to 98% of the light to maintain surfaces up to 7ºC fresher than other solutions, even under direct sunlight. Now, in Singapore they have developed a painting that mimics the sweating for which we regulate our temperature. Buildings that “sweat”. As we read in Sciencenewsa group of researchers from the Technological University of Nanyang is the responsible of a painting baptized as CCP-30 and what has special is not a color, but its operation. It is developed based on cement and combines three cooling strategies: radiative, reflection and evaporative (the latter, the one that uses our skin). And it works like an organism that sweats. The porous structure of the paint can retain up to 30% of its weight in water, which slowly releases the environment. It’s like the function of air conditioning dehumidificationbut passively. By absorbing water and dissipating heat, the released steam is cooler, contributing to cool the environment. SUV. If the sensation can be similar to that produced with ultrabrabic paint, why invest resources in replicating something that already exists? The main reason is that this ultra -ABANCA painting that reflects heat does not work at all well in Wet environmentssuch as Singapore itself, but also in Thailand and other areas where the moisture percentage is important. This reflected light is trapped by water vapor in the environment, and in large cities the creation of heat spotlights is encouraged. Come on, which contributes to embarrassment. The new porous painting, when not working by reflecting light and heat, does not have this problem and allows the buildings to be correctly isolated, fulfilling that passive cooling function. Promising. To hold their arguments, the researchers painted three houses with different types of paintings. One with a common white paint, another with a commercial painting that only uses radiative cooling and another with its new “sweat” painting. After two years exposed to the sun, rain and humidity of Singapore, while the first two became yellowish, the new formula continued with its white color. That is important not so much for aesthetics, but to continue being efficient reflecting the light. In addition, being prepared to absorb moisture, it does not crack, being another advantage. On the other hand, the house painted with CCP-30 reflected between 88% and 92% of sunlight even when it was wet, and emitted 95% of the heat it absorbed. Tandem with air conditioning. CCP-30 is designed to cover the outside of buildings, not homes or interior areas, acting as a first shield to combat heat. According to the area, the use of air-conditioning It will continue to be necessary to endure high temperatures, but researchers claim that a house covered with its new painting meant between 30% and 40% less use of air conditioning. It does not stop turning the building into a botijo. In the end, as we said, the use of paintings against heat is nothing new, but renewed formulas can help not only to refresh interiors, but to eliminate those urban heat spotlights in cities with a high percentage of moisture, calls “Heat islands”And the good thing about being a painting and not something that require a new construction It can be applied to existing structures without complex reform. I only ask that this type of painting arrives soon, but it is nice to know that passive ways of refrigerating households are being investigated, such as the Cement developed by the Public University of Navarra.

In the US they have realized that Covid has had an unexpected effect on its restaurants: it has triggered its production

by

The Covid has not sat badly at the US bars. At least if we talk about productivity levels. Even though pandemic He hit with viciousness to the hospitality of half the world (including the Spanish), He sank the billing From the sector and condemned not a few businesses at the close, American premises reached during the health crisis a level of labor productivity by 15% greater than they had before COVID, a notable increase that has not been diluted. The explanation is very simple: express visits. The Covid heritage. That the pandemic was devastating for the hospitality and forced to close Many businesses It is clear. However, however, a group of researchers from Chicago and New York universities asked a question that goes a little further: Did Covid-19 influence the productivity of the premises? And if so, in what sense? Is that effect still maintained? Their conclusions were reflected in A study that has just published the National Bureau of Economic Resarch (NBER) with a quite eloquent title and that gives a clue to which direction its findings point to: ‘The curious increase in productivity in US restaurants’. A percentage: 15%. The team of economists has not only found that effectively the performance of restaurants seemed to increase during the years of the health crisis. Has even encrypted that increase, as they need in The conclusions Of its report: “We verify that, after being practically constant for almost 30 years, real work productivity in restaurants increased more than 15% during the Covid-19 Pandemia.” The data is interesting because it does not only reflect a specific and past reality, related to the worst years of the Coronavirus. After sliding that percentage (15%) the researchers clarify that this turn has not yet diluted its effect. “This increase has been maintained even when many conditions have returned to prepondondemic levels.” And what was the reason? Clarified and calculated the increase in productivity, the following doubt was obvious: what was the reason? What did he answer? To answer all these issues, experts examined about 100,000 restaurants distributed by the US, focusing on aspects such as sales or the number of consumers attended by each employee. They also had access to information about visits thanks to mobile phones. The sample is wide, but presents certain characteristics that should be taken into account. To start the experts set in a very specific business profile, the Limited service hospitality (LSR), the one in which the interaction between the staff and the client is minimized, as in many premises of Fast food. The study in fact that focused on three subcategories: restaurants in the style of Taco Bell or McDonald´s, buffets and coffee shops such as Starbucks. For the sample to be wide, they covered more than 600 brands. Why this choice? The study It clarifies that the LSRs represent about 45% of the employment and sales of the sector in the US already throughout the last decades its productivity has evolved in a “very similar” way to the whole of the restoration sector. In addition, limited services offered an extra advantage: economists have complete information on their visits. Combing (thousands of) data. With all that information about the table, economists began drawing conclusions. And the first were striking. “Microdatos reveal significant growth in productivity, already measured in sales per employee or even in a more basic/physical average of the total number of customers per employee,” he says The study Published by Nber, which also rules out that this rebound can be explained by economies of scale, a greater weight of the sector or changes in demand. The experts also found that if the employees sold more it was not because they spent more time in their positions. When they were proven that the average weekly hours worked between July 2022 and June 2024 was 25.1 hours, “the same”, they clarify, that from 2006 to 2008. “In fact the current hours per worker are actually a bit below the pre-covid average from 2018 to 2019”. What is the cause? The rhythm. Or rather, the duration of visits. The researchers appreciated “significant descents in the amount of time” that customers spent in restaurants, with an increase especially pronounced in the group of consumers that remained in the premises 10 or even less minutes. That phenomenon was found during the pandemic years and did not seem to dissipate once the health crisis has been overcome. “The average permanence time of customers decreased and most of the reduction was due to the increase in the percentage of visits that lasted less than 10 minutes,” says the study. Your reading It is therefore clear: the increase in the performance of the restaurants “is strongly correlated” with the reduction of the time that customers pass in business, especially with express visits, which do not reach the quarter of an hour. Beyond the minutes. The data of the minutes clarified part of the mystery about the increase in performance (shorter visits translate into the possibility of attending a greater number of customers without increasing the templates), but letting another equally important question be bumping: why? Why was that increase in fleeting visits, 10 or even less minutes?
