China has concentrated thousands of fishing boats off Japan, and its idea is not to fish

The East China Sea is one of the more sensitive scenarios of the strategic balance in Asia for decades. territorial disputes, historical rivalries and the growing weight of new powers have turned these waters into a space where every movement is observed with a magnifying glass. There, apparently minor gestures usually fit into dynamic much deeperand China has just made a move. The diplomatic fuse. Japan’s detention of a chinese fishing boat within its exclusive economic zone, about 170 kilometers from Nagasaki, has rekindled a relationship already deteriorated between Tokyo and Beijing, with a certain island as a backdrop. He captain’s arrestafter refusing an inspection, occurs in a context of growing dispute marked by Japanese statements on Taiwan and the subsequent Chinese warnings its citizens to avoid traveling to Japan. Therefore, it is not an isolated episode, but rather the visible spark of a maritime tension that had been building for weeks. Images from space. AIS system data and the images by satellite show unprecedented concentrations of up to 2,000 fishing boats Chinese aligned near the median line between the two countries in the East China Sea. The formations, hundreds of kilometers long and with vessels separated by less than 500 meters, remained more than 24 hours in static positions despite adverse weather conditions. In other words, China was concentrating thousands of fishing boats off Japan, and its idea is not exactly to fish. The maritime militia and the “gray zone”. They counted on Nikkei that the vast majority of these fishing vessels are part of the so-called chinese maritime militiaa civil network that cooperates with the State and the Army in operations that do not reach the threshold of armed conflict. A priori, this strategy allows pressure to be exerted without formally deploying naval forces, thus making a direct response difficult. In other words, as we count A few weeks ago, what was presented as economic activity could become a test of maritime control or even the interruption of trade routes in the first island chain. Taiwan as a backdrop. Impossible to ignore it. The maneuvers coincide with statements by the Japanese government warning that a crisis in the Taiwan Strait would be an existential threat for Japan. Beijing, for its part, considers the island part of its territory and does not rule out the use of forcewhile Tokyo reinforces its deterrent posture. In this context, each movement in the East China Sea takes on a meaning that goes beyond fishing and is integrated into the regional strategic calculation. A pattern of sustained pressure. Furthermore, the activity is not limited to civil fleets. I remembered the Guardian that the Chinese coast guard has broken presence records around to the Senkaku Islandsalso known as Diaoyu in China, and has released images of patrols in disputed waters for the first time. Plus: the Liaoning aircraft carrier has expanded its radius of operations near Okinawa, while Beijing advances infrastructure on its side of the maritime median line. More than boats, an essay. Analysts interpret these concentrations like exercises of mobilization and coordination within the civil-military fusion plan promoted by Beijing. There is no doubt, the capacity of gather thousands of boats civilians at a strategic point in a short time sends a fairly clear message about the possibility of, for example, saturating maritime spaces without openly resorting to force. In this way, the pulse is no longer so much or only bilateral, but rather a warning to the entire region: China is perfecting tools to shape the balance of the Indo-Pacific, and it is doing so without firing a single shot.

Science has discovered what is the best time of day to be more concentrated and T0mar better decisions: at noon

As with the muscles, the brain offers its best version the more rested it is. For that reason, the experts recommend Identify the most productivity hours According to the chronotype of each person to carry out the most demanding activities and tasks at that time and have a better cognitive performance. Recent studies have revealed that fatigue affects remarkably when it comes to being more productive and even in decision making. Understanding this relationship helps to better plan schedules and improve performance. An example: Jeff Bezos never program meetings Beyond five in the afternoon Because doing so would imply raising the risk of making erroneous decisions. The moment of higher performance: noon. A study carried out by researchers from the universities of Messina and Bologna (Italy) analyzed more than 104,000 oral exams and found clear patterns at the time of the day when the students had more likely to approvehighlighting a peak that was not related to the difficulty of the exam but to the time in which the exam was taken. The researchers found that the global approved rate was 57%. However, the chart of probabilities to approve drew a bell shape, reaching its maximum point in the hours near noon, especially between 11:00 and 1:00 p.m. In comparison, the approved rates were remarkably lower early in the morning (between 8:00 and 9:00 hours) and the first hour of the afternoon (between 3:00 p.m. and 4:00 p.m.) without finding outstanding differences between those two moments. Without realizing it, we lose capabilities. To rule out that the downturn registered by the students at noon is conditioned by Knowledge of the subject of the examThe researchers also studied the behavior of teachers. The results of both groups led to the same conclusion: both students and evaluators experienced changes in their mental state and fatigue levels in the same time strip. This could contribute to the afternoon of the approval rate in exams is lower, since both the evaluator and the examinee are more fatigued and the teachers become more irascible and intolerant due to tiredness. If it’s 16:00, you’re guilty. The same conclusions arrived A group of researchers of the University of Columbia and the Ben Gurion University of the Neguev on the importance of the schedule in which judicial sentences and the increase in the severity of judicial decisions are issued. The investigators analyzed the behavior of several judges during the day and found that the favorable sentences to the defendants reached their peak as the pause to eat was approaching, reaching up to 70%. However, as the early hours of the afternoon progressed and the judges approached the next recess, this percentage progressively decreased to almost 0% by increasing the hardness of the sentences imposed. The “Baba” after the meal. This pattern suggests that our brain works best in mid -morning, and maintains that performance until eating. The explanation is found in the combination of biological factors such as Circadian rhythmswhich regulates energy and alert states during the day releasing more or less melatonin to the body to induce sleep state or activate alert and attention mechanisms. Researchers hypothesize that cognitive function continues This time curve naturallyimproving until noon and decreasing after eating, which coincides with the feeling of support after food. After lunch, there is a small increase in melatonin that can cause drowsiness and lower performance. Revitalizing naps. According to The published by Harvard Health Publishinga short nap after eating can improve the concentration and alert state if it lasts between 10 and 30 minutes. According to research in this regard, this type of naps increase the alert by more than 50% and competition by more than 30% compared to those who do not. However, the duration is key, and sleep more than the account It can be counterproductive. The study analyzed the behavior of Mediterranean adults and observed that making a short nap of less than 30 minutes is associated with a lower probability of high blood pressure (21%), while long naps (more than 30 minutes) are linked to the highest metabolic and cardiovascular risk (41%), as well as the higher perimeter of waist and blood glucose. Therefore, a brief nap after food, contributes to energy and maintaining mental acuity in the afternoon.

The good news for Russia is that the earthquake occurred in a remote area. The bad is that he concentrated his nuclear submarines

Yesterday we woke up with the news of A historical earthquake In an area of the planet that you had not heard in life. Makes sense, Kamchatka It is located at the easiest end of the Russian Eastern Eastern region, such an inhospitable place that has a “good” side of history: we had to tell human casualties in Russia. However, and due precisely to its geographical situation, that is where Moscow keeps part of Its nuclear arsenal. The epicenter of Russian underwater power. Yes, the Magnitude 8.8 earthquake who shook Kamchatka’s peninsula, one of the more powerful registered In modern history, he has put one of Russia’s most sensitive military facilities under the international focus: the naval bases of Avacha Bay. The movement, which generated tsunami waves in the Pacific and coincided with the eruption of the klyuchevskaya sopka volcanothere was only 100 kilometers from the heart of Russian nuclear deterrent power in the Far East. Although the Moscow authorities assure that There are no fatalities No serious damage, doubts revolve around the real state of Rybachiy, the main base of Russian strategic submarinesand from the Naval Complex of Petropavlovsk-Kamchatsky. Rybachiy: the bastion of nuclear deterrence. The Rybachiy base It houses the backbone of the underwater strategic fleet of Russia in the Pacific Ocean: The SSBN of the Borei and Borei-A classsuccessors of Ancient Deltacapable of carrying intercontinental ballistic missiles with nuclear heads. This installation, complemented by shipyards and missile load springs, represents a Central Piece of the Triad Russian nuclear, designed to guarantee the ability to retaliate in case of global conflict. In the area they also operate advanced attack submarines, like Yasen-M (indicated by the United States as one of the main threats under water), in addition to Oscar units and other submersibles of nuclear or conventional propulsion. The vulnerability of these assets in the face of extreme natural phenomena now generates serious unknowns. The Belgorod factor and the possesson weapon. To uncertainty is added the fact that Russia plans to move to Mysterious K-329 Belgorod To this same base. This submarine, the longest in the world, is a deep version Modified of the Oscar II class conceived to transport intercontinental nuclear torpedoes Poseidona strategic system also baptized as Status-6, designed to mock defenses and generate radioactive tsunamis. In addition, Belgorod is designed for underwater intelligence missions and undercover operations. The mere possibility that it would be in Avacha Bay during the earthquake The strategic interest of the natural catastrophe. Immediate technical risks and facilities. At the moment there is no clear evidence of damage to infrastructure or docked units. Bay’s own geography could have acted As a natural shield against the impact of the waves. However, they pointed out the Twz analysts that even minor variations of the sea level can cause critical problems: from submarines, violently hitting their ties (incidents known as Allision) until the entry of water in open gates or in ships subjected to maintenance. The robustness of the facilities, built with the hypothesis of an attack Nuclear in mind, reinforces the thesis that the damage has been limited, but does not completely eliminate uncertainty. The problem of concentrating a point. Beyond the punctual situation, the earthquake It exposes a structural dilemma: the risk of concentrating a substantial part of the Russian nuclear deterrence in a confined geographical enclave. The Avacha Baywith its shipyards, arsenals and strategic units, it constitutes a critical objective both from the military and natural point of view. The threat of an enemy attack was planned in design of the bases, but not that of a seismic phenomenon of historical magnitudescapable of questioning the safety of a key piece of the Russian nuclear triad. Strategic implications. In the background, the episode demonstrates how the stability of the world nuclear arsenal can depend on unpredictable natural factors. A single earthquake, in Second issueyou can compromise operability of strategic submarines whose function is to ensure the balance of nuclear terror. The fact that Kamchatka combines geological vulnerabilities With military assets In addition, the fragility inherent in global deterrence systems reveals. The international community, and especially the rival nuclear powers, will carefully observe the reports that emerge from Moscow, aware that nature, unlike strategic calculations, is impossible to deter.

82% are concentrated in just five regions

In full Tourism expansion international and with housing turned into the Great broken down With the head of the Spaniards, the government wants to cut short of short stay rents. To achieve it A few months ago presented its system of Single window and “registration number”, A new formula with which he intends to guarantee that those who rent their houses to tourists (even rooms) or through seasonal contracts do so complying with the laws of the sector. Now, with the new system of registration already advanced, the ministry has The first data. And they give us an interesting clue about the regions of Spain (surprisingly few) that suffer the most of the holiday rental pressure. What happened? That the government is putting the new system with which it intends to order the short -term rentals. A few days ago the Ministry of Housing and Urban Agenda (Mivau) revealed that since January 2, it has received more than 215,400 applications from owners interested in obtaining a “rental registration number” for its properties, the tuition that since July 1 they need to announce and operate on platforms such as Booking or Airbnb. Something more than half of those requests (134,300) arrived at the Ministry last month, which explains that not all are at the same point. According to the governmentthere are 94,200 that have already been activated definitively and 102,700 that have provisional green light, so you must still receive the guarantee of the College of Registrars. Another 18,500 have run worse luck and were revoked. Sum and follow requests. Although the system has just activated an idea of ​​the amount of short stay rents operating in the country. On Monday, a week after the balance of Mivau, Idealista published Updated figures that raise the total requests to more than 260,000, which shows that the drip of requests remains at a good pace. Moreover, the platform appointment A manager of the College of Registrars who estimates that at the end of June the 30,000 daily applications were reached, a rhythm that would now be around 10.00 or 15,000. Idealist Share Another interesting fact: To date, 22,000 homemade requests have been denied that have run out of the registration number that allows them to operate on the main digital platforms. The reason? Many incurred in the same three errors: their homes lacked license, they did not have the endorsement of the community of owners or can only be dedicated to residential use. For rent or season. Before following it is important to understand that not all owners request a registration number for the same. There are those who do it to rent their houses to tourists (the majority) and those who want to opt for the market of the season leasewhich is the one who demand, for example, the storms, researchers, students, athletes … in general any person who needs a house in which to stay a few months. The first case represents 78.9% of the requests until July. The second, 21.1%. Although these are different casuistics, both are considered “short -lived rentals” that from now on operate with the single digital window and a registration number that must be visible on the platforms. The objective, Underline Minister Isabel Rodríguez, is “to end the illegal tourist floors that expel families from their neighborhoods” and to use temporary rental to mock the law. What the data reveals. The figures Published by the Rodríguez department are interesting for another reason: they give us an interesting clue about the regions of the country most pressured by the short stay rentals, especially holidays. Of all the applications activated definitively at the end of June for tourist leases, the majority (82.22%) are concentrated in five regions: Andalusia, Balearic Islands, the Canary Islands, Catalonia and the Valencian C.. If we talk about provisional authorizations, that half dozen regions agglutinates 69.22% of permits. “This assumes that more than three out of four requests for registration numbers for tourist rental are concentrated in these five autonomous communities,” Clarify The Ministry of Housing. That 82% do not mean that the five communities agglutinate eight out of ten tourist rentals, but eight out of ten applications processed and approved today (the final photography can still vary). Still it is revealing. Can you get off in detail? Yeah. Mivau requires that at least at the end of June it was possible to identify Hot points in each of those five communities. In the case of Andalusia, which accumulated 49,397 requests, the vast majority (27,936) of Malaga. In the Canary Islands highlight Gran Canaria and Tenerife, which brought respectively 16,7100 and 13,300 applications of the 30,000 of the archipelago. Ministry data shows a similar trend in Catalonia or the Valencian Community. The bulk of the requests part of the provinces of Costa. Barcelona processed 9,500, Tarragona 6,600 and Girona 9,500, which between the three total 92% of the total. In C. Valenciana (21,900 applications in total), 14,500 left Alicante, 2,900 of Castellón and about 4,500 of Valencia.

The consumption of amphetamines in Spain is concentrated in an autonomous community. And we know it with a “single” trick

The surveys are very useful for “taking the pulse” to the population, but they can also lie (or at least fool) in many ways. Not this is not a cooking thing and how its results are interpreted: sometimes the lack of truth comes from the basis, and asking for some issues can be very delicate. And a great example of this is found in illegal substances, such as drugs. OEDA report. He last report prepared by the Spanish Observatory of Drugs and Addictions (OEDA) and the Government Delegation for the National Drug Plan He investigated not only social perceptions about the drug use of Spaniards, but also in their consumption habits. One of the most striking results was the “differential clear” in the pattern of amphetamine consumption: and the report found that the consumption of this substance was concentrated in an autonomous community: Euskadi. Estimates on the consumption of this substance in the Basque Autonomous Community far exceed the state average and records in the regions treated in the report. According to these calculations, the consumption of SPEED (name with which reference is also made to this substance) oscillates, according to areas Between 700 and 2,100 milligrams A day for every 1,000 inhabitants, while in the rest of the areas of study the average estimated consumption was 24 mg/(day 1,000 inhabitants). Not as easy as it seems. Estimating the consumption of this and other substances can be complicated. In the case of illegal drugs, its illicit nature makes the task of investigating its consumption complicated through simple surveys. To this we must add the social perception of drugs as taboo, something that also applies to legal substances such as alcohol and tobacco. So how are scientists save the scientists studying these substances? OEDA reports They consult the population to know their perception of this type of substance (both legal and illegal). However, to know drug use habits follow another strategy: search in waste. Sewage. Specifically, in wastewater. Our body discards these substances or their metabolites (the compounds derived from the medicalization of a compound) through the urine, which implies that the tests end up in our wastewater and from there in the water treatment plants. The equipment responsible for the analysis took water samples in a series of purifying stations sewage (WWTP) distributed in various autonomous communities, 28 in total. The samples were taken over a week (usually in spring) in the years between 2021 and 2023. In some of the stations additional samples were taken in the second half of the year. Different habits. None of the substances analyzed presented a pattern of consumption as centered as the case of amphetamines, although in the case of cannabis, for example, some trends with the Catalan stations and the Canarian station can be interviewed indicating the areas of greatest consumption. On average, a consumption of 13 g/(day 1,000) of THC (tetrahydrocannabidiol) was estimated. The study of wastewater also gives us information about legal substances such as alcohol and nicotine. The median reading of the national WWTP ethanol showed an estimated consumption of 7.6 l/(day 1,000 inhabitants). In the case of nicotine on the other hand, the global median indicated a consumption of 1,641 mg/(day 1,000 inhabitants). Not only Spain. This type of analysis based on wastewater is not exclusive to Spain. At European level we can also find similar studies. Another recent study Performed by the European Union Drugs Agency (EUDA) analyzed consumption patterns in European countries and observed that Spain (as well as the Netherlands) showed a relatively high consumption of substances such as cocaine, MDMA, THC or ketamine. Of course, in this case, the study analyzed less water treatment stations: six located in different parts of the Mediterranean coast and one more in Galicia. The concentration of stations in the Mediterranean and absence of samples in other highly populated areas such as Madrid implies a serious limitation in this study if we want to extrapolate its results to the whole.
