　　Recently, the China delegation attending the 74th UN General Assembly formally submitted four documents to the UN. Among them, the Report on Global Big Data Supporting Sustainable Development Goals compiled by China Academy of Sciences shows China’s exploration and practice of using global big data technology to support the implementation of the 2030 sustainable development agenda and policy decisions.

　　With the rapid development of science and technology, the blue planet of the earth is becoming more and more "transparent" in the fine network woven with big data. Recently, China Academy of Sciences officially released "Report on Global Big Data Supporting Sustainable Development Goals" (referred to as "Report"). What’s the mystery in the report? Please follow the Economic Daily reporter to find out.

　　Focus on new methods and accumulate new data

　　In 2015, 193 Member States of the United Nations adopted "Changing Our World: Agenda for Sustainable Development in 2030", and countries around the world actively implemented the Sustainable Development Goals (SDGs) in the increasingly severe global problems.

　　However, Guo Huadong, head of the Earth Big Data Science Project and academician of China Academy of Sciences, admitted that the monitoring of the implementation process of SDGs is facing arduous challenges. Among them, the serious shortage of indicator data is one of the main challenges in monitoring SDGs: the imperfect and inconsistent data statistical system and the lack of indicator system are the key reasons for the lack of data and low quality. Therefore, it is still a difficult problem to ensure data reliability and scientifically establish SDGs evaluation index system.

　　Guo Huadong showed a set of data to reporters: among the 17 sustainable development goals, 169 specific goals and more than 230 indicators of the sustainable development agenda in 2030, only 45% were assessed with methods and data, 39% were assessed with methods and data, and 16% were assessed without methods and data. "It is the most urgent task for the United Nations to achieve a breakthrough in the evaluation of indicators with methods, no data, no methods and no data."

　　"The evaluation of indicators mainly depends on the investigation of statistical departments in various countries. However, the traditional means of statistical investigation is insufficient in the timeliness, spatial resolution and cost of indicator evaluation, which has been widely recognized around the world." Chen Xiang, a researcher at the Institute of Aerospace Information, China Academy of Sciences, told reporters that some countries are rich in agricultural resources, but because of the lack of methods to evaluate the agricultural situation, they have no food to eat. For example, mango trees in Mozambique are all over the country, but the mango resources are still unclear and have not been effectively utilized.

　　In this regard, Chinese scientists have stepped forward and aimed at "Earth Big Data" to carry out scientific research. "As an important aspect of scientific and technological innovation, big data is bringing new research methods and means to scientific research, which is expected to promote the emergence of a new research paradigm." Guo Huadong said that Earth Big Data is massive, multi-source, heterogeneous, multi-temporal, multi-dimensional, highly coupled, non-stationary and unstructured, and is becoming a new key to understanding the Earth, a new engine for knowledge discovery and a new means of decision support.

　　On January 1, 2018, China Academy of Sciences officially launched the Class A strategic pilot science and technology project "Earth Big Data Science Project", which is dedicated to building a platform for sharing big data and cloud services covering resources, environment, biology, ecology and other fields, and promoting technological innovation in the field of earth big data and major breakthroughs and scientific discoveries in earth system science. The Report on Global Big Data Supporting Sustainable Development Goals is the result of more than one year of special implementation.

　　Guo Huadong introduced that the Report selected a number of typical cases for in-depth study by focusing on specific goals such as zero hunger, clean drinking water and sanitation facilities, sustainable cities and communities, underwater organisms and terrestrial organisms, and the data analysis results presented can provide useful reference for other countries to implement the 2030 Agenda and provide China’s solutions for solving more global and regional sustainable development problems.

　　Typical case interpretation of scientific basis

　　Earlier, IUCN lowered the endangered level of our national treasure giant panda from "endangered" to "vulnerable" according to its own evaluation criteria. Where did the basis for this judgment come from? Is the giant panda really safe?

　　In this issue of the Report, the answer is given. According to the Report, from 1976 to 2013, the population of giant pandas increased, but the habitat since 2001 was smaller and more fragmented than when giant pandas were listed as endangered species in 1988. "Therefore, it is unreasonable to reduce the endangered level of giant pandas simply on the basis of population size. The assessment of endangered category needs to integrate both population and habitat factors in order to carry out protection more objectively." Guo Huadong said.

　　For example, where is the best place for friends to enjoy public transport services conveniently and quickly? In terms of sustainable cities and communities, the Report points out that citizens in Macao, Hong Kong, Shanghai and Beijing have the most convenient access to public transport, and the proportion of public space in Beijing is the highest in the country. The average proportion of people in all provinces in China who can use public transport conveniently is 64.28%, among which the eastern region is generally higher than the central and western regions and the southern provinces are generally higher than the northern provinces. From the scale of prefecture-level cities, the proportion of people who can easily use public transportation in densely populated cities is generally higher than that in sparsely populated cities.

　　In terms of clean drinking water and sanitation facilities, the Report shows that the surface water quality in China improved slightly in 2017 compared with that in 2016, and the surface water quality in the western region was generally better than that in the eastern region, with the surface water quality in Xinjiang and Tibet being the best. After years of continuous treatment, the quality of surface water in China has been significantly improved, but some eastern provinces and cities still need to further improve their treatment level.

　　In this way, 12 research cases about China are presented in this issue of the Report. In addition, the project also carried out in-depth research on data and methods for the global urbanization process, glacier degradation in high Asia, and national water resources situation in Africa and Central Asia.

　　For example, the impact of global atmospheric carbon dioxide concentration on climate change should be assessed to strengthen education and publicity on climate change mitigation, adaptation, impact reduction and early warning. "We can see that the annual increase of global atmospheric carbon dioxide concentration mainly comes from man-made emissions. The occurrence of extreme climate has also enhanced carbon dioxide emissions in some terrestrial ecological areas, leading to an increase in interannual incremental fluctuations. " In this regard, Guo Huadong suggested that while controlling man-made carbon dioxide emissions, we should also scientifically repair and manage sensitive terrestrial ecosystems to reduce the impact of extreme climate on ecosystems.

　　Guo Huadong told reporters that the SDGs assessment progress shown in the Report provides a solid scientific basis for supporting UN agencies to promote sustainable development-related cooperation in the future, and supporting countries related to the Belt and Road Initiative to build a more perfect sustainable development target assessment system.

　　March towards the goal of sustainable development

　　Practice has proved that earth big data, as a new scientific methodology, has great application value and can provide monitoring and evaluation services for sustainable development goals in China and the vast number of developing countries and regions.

　　Guo Huadong said that the sustainable development goals of the United Nations and China’s national development strategy are mutually supportive. This issue of the Report is a scientific and technological innovation platform for China to serve the sustainable development goals of the United Nations, a concrete contribution to the realization of the sustainable development goals by using big earth data, and a realistic case in which China implements a technology promotion mechanism to promote the realization of the sustainable development goals, including data methods, which can be popularized in other countries.

　　The "Earth Big Data Science Project" project takes a longer view. Guo Huadong bluntly said that the ultimate goal of the project is to build an international earth big data science center. These include: launching CASEarth small satellites to improve data acquisition capabilities; Build a basic platform for earth big data cloud services and improve data processing capabilities; Build a digital geoscience platform to improve decision support ability; Monitoring and evaluation of SDGs indicators in global, regional, national and typical regions will be realized around the Belt and Road Initiative and beautiful China.

　　"Special projects can constantly give full play to their own characteristics and advantages, take the technology promotion mechanism as the purpose, invest in high-quality and precise scientific and technological strength, and achieve innovation in many aspects such as data sources, methodologies, implementation cases and decision support for sustainable development goals, and provide more reliable data basis and new research theories and methods for major issues related to sustainable development goals." Guo Huadong said.

　　Promoting the implementation of the 2030 Agenda for Sustainable Development has become the core task in the field of global development. "More and more countries, regions, organizations and enterprises are participating in it and working together to promote the UN’s sustainable development goals." Zhang Yaping, vice president of China Academy of Sciences, said that in the future, the special project of "Earth Big Data Science Project" will continue to carry out research on sustainable development goals, deepen cooperation inside and outside the institute, at home and abroad, strengthen the integration of relevant research results, and strive for more scientific and technological workers to join in and make greater contributions to the UN Agenda 2030.

Bucks "revenge" succeeded. Figure CFP

From being eliminated by 1-4 to completing the "sweeping" by 4-0, the Bucks completed their revenge on the Heat in the most extreme way.

On May 30, Beijing time, the NBA playoffs continued to be fiercely fought. In a group of matchups in the East, the Bucks defeated the Heat 120-103 and completed the "sweep" with a big score of 4-0, becoming the first team to advance in this year’s playoffs. Bucks’ core "letter brother" scored 20 points, 12 rebounds and 15 assists in 36 minutes, helping the team create history.

In another game, the Blazers beat the Nuggets 115-95, making the total score 2-2. Lillard didn’t feel good, but the team’s new aid Powell completed the "redemption" and scored 29 points, tying the personal playoff scoring record.

In addition, the top 40 is about to start, but there is bad news from the national football team. According to domestic media reports, the national football striker Fernando was accidentally injured in training and had to be out of action for at least three weeks, which means that the "scooter" basically missed all four games in the top 40 stage.

The first round of 2020/2021NBA playoffs G4: Milwaukee Bucks vs Miami Heat. People’s visual map

With "sweeping" revenge, the Bucks advanced to the second round of the playoffs.

In fact, at the end of this season’s NBA regular season, when the Bucks encounter the Heat again, the outlook of these two teams has been very different from last year. Most people think that the bucks can advance to the next round, but they didn’t expect that the bucks would use this "extreme" way to complete their revenge on the Heat.

On May 30th, in the fourth game of this round, the Bucks finally defeated their opponents by 120-103. In all four games, the Bucks ended in great victories, and finally became the first team to advance in the eight-group matchup in the playoffs with a total score of 4-0.

In the playoffs last season, when the Bucks were about to be eliminated, the helpless "letter brother" sitting on the bench left that classic expression, but now, his state is completely different. In the farewell game to the Heat, Brother Alphabet played for 36 minutes, made 8 of 18 shots, and scored 20 points, 12 rebounds and 15 assists.

This is the first "triple-double" of "Brother Alphabet" in his playoff career, and he has also become the fifth player in the history of the league to get "20+12+15" in a single playoff game.

On the other hand, Butler, the core of the Heat, changed from the strength of last season to the weakness of this season. In the last game, Butler played for 38 minutes, made 4 of 15 shots, made 0 of 2 three-pointers, and scored 12 points, 10 rebounds and 10 assists. Although he also got the "triple double", Butler’s efficiency was only -18.

According to statistics, Butler averaged 14.5 points, 7.5 rebounds and 7 assists in this series, with a shooting percentage of only 29%, a three-point shooting percentage of 26% and a positive and negative value of only -21.

The core state of the team is not good, so it is naturally difficult for the whole heat to find the state. An interesting detail is that Haslem, the team’s meritorious veteran, stormed off the bench during a timeout and then gave a passionate speech to the players, but he still couldn’t change the fate of being swept away.

This defeat also made the Heat the third team in NBA history to be swept out by a net win of more than 60 points.

The first round of 2020/2021NBA playoffs G4: Denver Nuggets vs Portland Trailblazers. People’s visual map

The Nuggets lost by 20 points, and the Blazers tied the score.

When the bucks "swept" the old rival Heat, the Nuggets became more and more entangled with their old rivals.

On May 30th, in another NBA playoff, Portland Trailblazers at home beat Denver Nuggets 115-95, making the total score of this series 2-2.

In this game, Jokic, the core of Nuggets, was in an average state, making only 7 of 18 shots and 1 of 4 three-pointers with only 16 points and 9 rebounds. Even more worrying data is that Jokic’s personal positive and negative values are as low as -32.

Personal positive and negative values of -32 also set a new low in Jokic’s NBA career (regular season+playoffs). In the 27 minutes he was present, the Nuggets lost by 32 points to the Blazers, and in the 21 minutes he was absent, the Nuggets won by 12 points.

"We were beaten up, which was embarrassing." Nuggets player JaMychal Green said after the game. The team coach Malone said frankly, "We didn’t play hard enough tonight. I can’t believe we’re really talking about playing hard in the playoffs. This (playing hard in the playoffs) should be taken for granted. "

In contrast, the Trailblazers are indeed the better side in this game in terms of desire to win and on-the-spot performance.

In fact, Lillard, the star of the Blazers, didn’t play well either. He made 1 of 10 shots in this game, but the Blazers still won 20 points. The key is that when the star of the Blazers was depressed, other players could stand up-five players in the Blazers scored in double figures, Powell scored 29 points, mccollum scored 21 points, nurkic scored 17 points, and Anthony scored 12 points when he came off the bench.

"When the game goes like this, I just try to adjust. I can’t vote correctly, but I won’t force my hand when I see that others feel good. " Lillard talked about his performance after the game and praised his teammates. "From the beginning, Norman (Powell) found his state, and then CJ (mccollum) also hit the ball. In the restricted area, nurkic can also complete the end. "

Fernando. People’s visual data map

　Fernando has a strain or needs to rest for 3 weeks, and missed the top 40.

On May 30th, the national football team will play Guam in the preliminaries. At the pre-match press conference, the national football coach Li Tie confirmed that Fernando could not play due to injury.

"Because there was a temporary accident two days before the pre-match training, Fernando suffered a little injury and went to the hospital for an examination. From my point of view, he will definitely not be able to play this game and will not be included in the 20-person list. We will see if he can play the next game according to the doctor’s diagnosis and judgment."

Li Tie said at the press conference that whether he can play in the following games will depend on his recovery. However, according to the latest report of Beijing Youth Daily, Fernando was injured before. Usually, he has to rest for at least three weeks, which means that Xiaomoto has basically missed all four national football games in the top 40 stage.

It is worth mentioning that in the top 40, Lei Wu returned from Spain, and naturalized player Fernando was selected for the first time, which obviously improved the strength of the national football front line. However, Fernando’s injury will have a little impact on the employment of the first game of the national football team.

Li Tie said: "Now, for us, playing Guam is more like an encounter, and the opponent has not played any games. We just do our best and play what we have trained on the court and what we have accumulated over the past year."

2021 Belgrade Open Men’s Singles Final: Djokovic won the championship. People’s visual map

Deyo lost four serves and still won.

On May 29th, Beijing time, the 2021 ATP250 Belgrade Open came to an end. Djokovic, the top seed of the tournament, lost four serves, but eventually defeated Morquin, a qualifier, 6-4/6-3 in straight sets, and won the men’s singles championship in Belgrade for the third time after 2009 and 2011.

At the same time, he also raised the number of singles champions on the individual tour to 83, ranking fifth in the overall list of history.

In the first game, both sides broke each other’s serve as soon as they came up. In the middle stage, the break-breaking war continued. Finally, Djokovic won the first set 6-4 by relying on the advantage of keeping one game more. In the second set, the game returned to the normal track, and Djokovic only lost one serve point in his first three serves.

In the 6th game, Deyo took the lead in breaking Morquin’s serve in the tug-of-war, but then his own serve was not saved, and Morquin immediately broke it back. Fortunately, in the eighth game, Djokovic once again seized the opportunity to successfully break again, and kept his serve steady in the ninth game, thus winning the next game with 6-3, and then beating Morquin with a big score of 2-0 to win the second championship of the season to welcome the arrival of the French Open.

Deyo also became the sixth player to win two singles titles on the ATP Tour this season after Bachelard Shvili, Hulkaqi, Nadal, Sisyphas and Zvilev Jr.

At the same time, this is also the 16th clay championship won by the Serbian King in his career.

Summer middle school football match.

"Haigang-SAIC" Cup Xinmin Evening News Summer Middle School Football Competition started in five major divisions.

On May 29th, 2021, the 36th "Harbor-SAIC" Cup Xinmin Evening News Summer Middle School Football Match kicked off. The event launched a brand-new slogan-dream the future, set sail new.

It is reported that this year’s evening paper cup will create two concepts: "the most competition areas and the richest’ new’ ideas". This year, evening paper cup actively responded to the national strategy of integrated development of the Yangtze River Delta, and went out of Shanghai for the first time to build a platform for youth football competition in Shanghai, Jiangsu, Zhejiang and Anhui, and to build three major competition areas: Huangshan in Anhui, Taizhou in Zhejiang and Suzhou in Jiangsu.

Under the guidance of Shanghai’s social responsibility to help Xinjiang, this year, evening paper cup will give full play to its public welfare attributes, open up the Kashgar Division in Xinjiang, and bring football happiness to local teenagers with green dreams.

It is worth mentioning that at the evening paper cup finals in August this year, the organizing committee will invite the champion team of the Shanghai Division to compete with the champion teams of the other four divisions in the "Harbour-SAIC Cup Xinmin Evening News Summer Middle School Football Tournament", which will start a wonderful showdown between the champion teams and help the high-level youth in China learn football skills.

Wu Lei, a striker of China’s national team and now playing for Spanish in La Liga, has served as the ambassador of Xinmin evening paper cup for two consecutive years, and had a live exchange of skills with Shanghai football teenagers. This year, the tournament welcomed Oscar, the captain of Shanghai Harbour Football Club and a famous star, and he officially became the image ambassador of this tournament.

During the competition, Oscar will come to the edge of the competition to interact with the participating students. At the same time, Li Shenglong, a seaport player, and Abram Khan, respectively, served as a dream assistant in the Shanghai Division and a public welfare ambassador for public welfare action in Xinjiang.

In addition, the long-awaited mascot "Yan Xiaoxin" officially appeared. "Yan Xiaoxin" is inspired by the slogan of the organizer Xinmin Evening News Agency "Flying into the homes of ordinary people". Since this tournament, this cute swallow will witness and accompany the growth of generations of football teenagers.

In order to do a good job in the vaccination work in Covid-19 of the whole army, further popularize the vaccination knowledge, and ensure that the vaccination work of the whole army is scientific, rigorous, safe and standardized, and vigorously and orderly and effectively promoted, recently, the reporter interviewed experts related to the joint prevention and control mechanism of the army in response to public health emergencies.

Reporter: What is Covid-19 vaccine and what kinds are there at present?

Expert: Covid-19 vaccine, called novel coronavirus preventive vaccine, is an innovative vaccine to prevent and control diseases caused by Covid-19 infection. Domestic Covid-19 vaccine research and development technologies are mainly divided into five types, namely: inactivated vaccine, adenovirus vector vaccine, attenuated influenza virus vector vaccine, recombinant protein vaccine and nucleic acid vaccine. Up to now, there are four kinds of vaccines in China, such as inactivated vaccines from Sinopharm Group Co., Ltd. "Zhongsheng Wuhan" and "Zhongsheng Beijing", inactivated vaccines from Beijing Kexing Zhongwei Biotechnology Co., Ltd. and adenovirus vector vaccine developed by Academy of Military Sciences and Kangxinuo Company, which have been approved for conditional listing. The recombinant protein vaccine jointly developed by Institute of Microbiology of China Academy of Sciences and Anhui Zhifeilong Kema Company agreed to be used urgently after evaluation and demonstration.

Reporter: Is it necessary for the general population to get novel coronavirus vaccine?

Expert: novel coronavirus is a new virus, and almost everyone is susceptible to novel coronavirus, so it is very necessary to get vaccinated. As a group that needs to perform all kinds of tasks at any time, military personnel should be vaccinated except for contraindications.

Reporter: What are the main features of recombinant novel coronavirus vaccine (adenovirus vector) compared with other COVID-19 vaccines approved by China?

Expert: At present, COVID-19 inactivated vaccine needs to be vaccinated twice in the whole process, and it is recommended that the interval between two doses should not be less than 28 days. Those who need to complete the whole process of COVID-19 inactivated vaccine as soon as possible because of going abroad or working in high-risk areas can be vaccinated twice with COVID-19 inactivated vaccine at the shortest interval specified in the vaccine instructions; The recombinant protein vaccine jointly developed by Institute of Microbiology, China Academy of Sciences and Anhui Zhifeilong Kema Company needs to be inoculated three times. Inoculation is to make the antibody reach a certain level to resist the disease. Generally speaking, inactivated vaccines need to be vaccinated many times, and the immunity should be strengthened regularly to achieve sufficient antibody titer in the body. The first vaccination usually does not provide protection, and the protective immune response usually occurs after the second dose of vaccination.

Recombinant novel coronavirus vaccine (adenovirus vector) only needs to be inoculated with one dose, which can produce cellular immunity and humoral immunity after 14 days of inoculation, providing double protection for human body. It is the only single-dose COVID-19 vaccine approved for use in China.

Reporter: What is the principle of adenovirus vector technology?

Expert: human adenovirus type 5 (Ad5) is a common respiratory virus. After being modified, Ad5 will not replicate in human body. Insert the gene encoding Covid-19 spike protein (S protein) into Ad5 vector, which is equivalent to rocket and S protein gene is equivalent to satellite. The vector carries the S protein gene into human cells to synthesize Covid-19 S protein, and S protein is used as antigen to stimulate the immune response of the body. Only Covid-19’s S protein enters the human body, and there are no other Covid-19 components.

Reporter: What is the protective effect of recombinant novel coronavirus vaccine (adenovirus vector) and its protective effect on Covid-19 mutant?

Expert: At present, the data of global phase III clinical trials show that after 14 days of single injection of recombinant novel coronavirus vaccine (adenovirus vector), the protective effect on severe COVID-19 is 95.5%, and the overall protective effect on all symptoms of COVID-19 is 68.8%. The results of neutralizing antibody cross experiment showed that the vaccine had protective effect on Covid-19 mutant.

Reporter: How safe is the vaccine in Covid-19?

Expert: Covid-19 vaccines, like other vaccines, have a series of safeguards for quality and safety management, and there are clear requirements in the process of vaccine research and development and production. Vaccines must undergo strict animal experiments and clinical research before they are registered, and a strict batch issuance system should be implemented before they are used. Therefore, the vaccines approved by the state for marketing are all safe and effective to meet the qualified standards.

The recombinant novel coronavirus vaccine (adenovirus vector) was approved for conditional marketing in National Medical Products Administration based on the results of Phase III clinical trials conducted by more than 40,000 people in five foreign countries, and the vaccine was safe. Up to now, hundreds of thousands of people have been vaccinated, and no serious adverse reactions related to vaccination have been found.

Reporter: What are the main adverse reactions that may occur after the recombinant novel coronavirus vaccine (adenovirus vector) is inoculated?

Expert: Like any other vaccine, there may be some common adverse reactions after inoculation with recombinant novel coronavirus vaccine (adenovirus vector). After summarizing all the adverse reactions collected in the clinical trials of phase I, II and III vaccines and in emergency use, the common adverse reactions at the inoculation site are pain, swelling, itching, erythema and induration. Common systemic adverse reactions include fever, headache, fatigue, myalgia, lethargy, nausea and diarrhea. The severity of adverse reactions observed in this series of clinical trials is mainly Grade 1 (mild), and the incidence of adverse reactions of Grade 3 and above is 7.40%. For those with fever, antipyretic drugs can be taken, and other common adverse reactions generally do not need special treatment, and usually can be relieved within 48 hours. If the symptoms are serious or you can’t judge the severity by yourself, you should seek medical advice in time.

Reporter: Who are the people who are not allowed to vaccinate in Covid-19?

Expert: Vaccination contraindications for vaccines in Covid-19 must be strictly observed in Covid-19’s vaccine instructions. Usually, people who are seriously allergic to vaccines or any ingredients in vaccines are contraindicated. For patients with fever, acute diseases and acute authors of chronic diseases, they generally belong to the object of suspension of vaccination.

Reporter: Can people in allergic period be vaccinated with recombinant novel coronavirus vaccine (adenovirus vector)?

Expert: Allergy is an important factor for doctors to consider when vaccinating. People who are allergic to vaccines or vaccine ingredients and have had allergic reactions to vaccination in the past are not suitable for vaccination; People with other serious allergic history (such as asthma, severe eczema, etc.) are not recommended to be vaccinated; For allergic people with pollen allergy, nasal congestion, runny nose or slight rash, it is recommended to stagger the allergic period, and the mild symptoms can be vaccinated according to the doctor’s advice.

Reporter: Can cancer patients and people with chronic diseases be vaccinated with recombinant novel coronavirus vaccine (adenovirus vector)?

Expert: People with nervous system diseases and immune system diseases are not suitable for vaccination. Basic patients such as diabetes and hypertension that can be controlled by drugs can be vaccinated during the stable period. For cancer patients, it is necessary to consult oncologists and determine whether they can be vaccinated according to the drug use.

Reporter: What are the precautions before and after Covid-19 vaccination?

Expert: Before vaccination, the vaccination doctor will ask about the health status, please tell the relevant information truthfully; After the inoculation is completed, it is necessary to keep on-site observation for 30 minutes, keep the injection site dry on the day of inoculation, pay attention to personal hygiene and arrange rest properly; Avoid contact with previously known allergens and common allergens within one week after inoculation, and try not to drink alcohol, eat spicy food or seafood. It is recommended to have a light diet and drink plenty of water.

Reporter: If there are serious adverse reactions after vaccination with Covid-19 vaccine, how should I report and handle them?

Expert: According to past experience, acute adverse reactions after vaccination usually appear within 30 minutes after vaccination. Please keep under observation as required and inform the doctor at the vaccination site in time. If there are serious adverse reactions after leaving the inoculation site, you should seek medical treatment in time and report to the doctor at the inoculation site.

Reporter: How long is the immune persistence of Covid-19 vaccine? Is it necessary to strengthen immunization?

Expert: At present, the immunization program of recombinant novel coronavirus vaccine (adenovirus vector) is one dose, and the observation of immune persistence after single dose vaccination is still in progress. The current data prove that it is effective within at least 6 months. Previously, the vaccine research and development team observed the immune persistence of Ebola vaccine using the same adenovirus vector technology and found that it still had a high antibody level after two years of inoculation.

Reporter: Can recombinant novel coronavirus vaccine (adenovirus vector) and inactivated COVID-19 vaccine be used together?

Expert: At present, there is no relevant information about alternative vaccination and combined application. Please refer to the national policy guidance and COVID-19 vaccine instructions.

Reporter: Will nasopharyngeal swab test positive for nucleic acid after inoculation with recombinant novel coronavirus vaccine (adenovirus vector)?

Expert: No. The nucleic acid test is Covid-19 gene, and the current vaccine will not cause COVID-19, nor will it make Covid-19 nucleic acid test positive because of vaccination.

Reporter: Can Covid-19 vaccine be inoculated with other vaccines such as HPV vaccine, influenza vaccine and rabies vaccine?

Expert: It is not recommended to vaccinate with other vaccines at the same time. It is recommended to vaccinate with other vaccines at least 2 weeks apart to minimize unexpected interaction, and at the same time, it is necessary to closely observe the reaction after vaccination.

Reporter: Is it necessary to vaccinate people who have had COVID-19 or who have no symptoms?

Expert: The existing research data show that it is rare to get reinfected in Covid-19 within 6 months after infection. Previous COVID-19 virus-infected people (patients or asymptomatic infected people) can receive one dose after 6 months on the basis of full notification.

Reporter: Do I still need to wear a mask after Covid-19 vaccination?

Expert: Before the population immune barrier is established, even if some people are vaccinated, everyone’s awareness of prevention and control and prevention measures cannot be relaxed. On the one hand, the success rate of vaccine immunization is not 100%, and a small number of vaccinated people may get sick during the epidemic period, which is related to the characteristics of the vaccine itself and the personal physique of the recipients; On the other hand, in the absence of an immune barrier, Covid-19 is still easy to spread.

Reporter: Do you need to check the antibody production? How to check the antibody? If it is negative, do you need to replant?

Expert: It is not recommended to check antibodies. The production of specific antibodies in human body is generally obtained by natural infection or vaccination. It is suggested that anyone who meets the vaccination conditions should be vaccinated as long as they are not clearly infected with Covid-19 or have suffered from COVID-19, and there is no need to test antibodies before and after vaccination.

Reporter: Do you still need to do nucleic acid testing after Covid-19 vaccination?

Expert: Vaccination can reduce the risk of infection to a certain extent, but the protective effect of any vaccine can not reach 100%. If necessary, we should still cooperate with relevant departments to carry out nucleic acid testing.

Phoenix Network Technology News (Author/Jia Nan) On November 17th, the Qualcomm Snapdragon Summit held in Hawaii entered the second day. Following the release of the second generation Snapdragon 8 mobile platform yesterday, today’s content will mainly focus on terminal platforms other than smart phones. For the augmented reality (AR) platform, Qualcomm launched the first generation AR2 platform in Snapdragon, and the next generation CPU core Oryon in Qualcomm.

As a part of Qualcomm’s augmented reality product, the first generation Snapdragon AR2 was manufactured by 4nm process, and adopted multi-chip distributed processing architecture and customized IP modules, including an AR processor, an AR coprocessor and a connection platform. On the basis that the space occupied by the main processor is reduced by 40% compared with the previous first-generation Snapdragon XR2 platform, the AR performance of the first-generation Snapdragon AR2 is improved by 2.5 times, while the power consumption is reduced by 50%, and the power consumption of AR glasses is allowed to be less than 1W.

At the same time, through this platform, AR devices can classify data: delay-sensitive content such as games and videos will be directly sent to head-mounted devices for processing, while other more complex data requirements will be handed over to compatible devices such as smartphones and PCs equipped with Opteron processors.

As an AR processor, the first generation Snapdragon AR2 supports up to nine concurrent cameras for user and environment understanding. At the same time, the perceptual performance of its hardware acceleration engine, AI accelerator and re-projection engine has also been improved. The AR coprocessor included in the platform can support eye tracking and iris authentication for visual focus rendering by aggregating camera and sensor data.

In terms of connectivity, the first generation of Snapdragon AR2 platform integrates the FastConnect 7800 connection system of Qualcomm and supports the connection of Wi-Fi 7. Officials say that it can reduce the time between AR glasses and mobile phones or host terminals to less than 2 milliseconds.

In addition to the first generation Snapdragon AR2 platform, Qualcomm also released the second generation Qualcomm S5 audio platform and the second generation Qualcomm S3 audio platform. Both of them support the Snapdragon Sound high unobstructed listening technology, and are optimized for the second generation Snapdragon 8 mobile platform, supporting dynamic spatial audio, lossless music streaming, 48ms low delay, LE Audio and the third generation Qualcomm adaptive active noise reduction technology.

In addition, Qualcomm also announced its next-generation CPU core in Snapdragon platform-ORYON, which is expected to be delivered in 2023.

Rationally arrange a number of biomass power generation projects, build waste incineration power generation facilities with high environmental protection standards, and build biogas utilization projects in combination with landfill sites, livestock and poultry farms and wastewater treatment facilities.

　　4. Improve the quality of industrial fuels. Strictly control the sulfur ash content of coal, control the sulfur content of coal in thermal power plants below 0.7%, control the sulfur content of coal in industrial boilers and kilns below 0.6%, and control the sulfur content of fuel below 0.8%. Improve the proportion of coal preparation in coal consumption. It is forbidden to import inferior coal with high ash content and high sulfur content, and the import of high sulfur petroleum coke is restricted. Apply and popularize clean coal utilization technology.

　　5. Strengthen the management of high-pollution fuel no-burn zone. From 2014, the built-up areas of national environmental protection model cities and the urban built-up areas in the Pearl River Delta region should be designated as high-pollution fuel no-burn areas, and the areas of other cities should reach more than 60% of the urban built-up areas; Before the end of 2017, all urban built-up areas in the province should be designated as high-pollution fuel no-burn zones, and the scope of no-burn zones should be gradually extended to the suburbs. It is forbidden to burn raw (loose) coal, washed coal, coal water slurry, honeycomb coal, coke, charcoal, coal gangue, slime, coal tar, heavy oil, residual oil and combustible waste in the no-burn zone. It is forbidden to directly burn highly polluting fuels such as biomass, diesel, kerosene, artificial gas and other fuels with excessive pollutant content, and it is forbidden to build, modify or expand combustion facilities such as boilers, kilns and heat conduction oil furnace that burn highly polluting fuels.

　　(9) Strengthen environmental law enforcement and improve the efficiency of environmental supervision.

　　1. Strengthen regulatory capacity building. Improve the provincial, city, county, township (street) four-level environmental supervision system, strengthen the construction of environmental monitoring team, and enhance the ability of environmental supervision. By the end of 2014, we will complete the task of building a vehicle emission supervision platform at the provincial and municipal levels. Strengthen the supervisory monitoring of pollution sources, include boilers with more than 20 tons of steam and volatile organic compounds emitting enterprises in typical industries into the scope of supervisory monitoring, and implement online monitoring of volatile organic compounds in key enterprises on a pilot basis.

　　2. Strengthen supervision and inspection. The environmental air quality indicators of all localities are incorporated into the evaluation index system of environmental protection. According to the assessment requirements of the state for air pollution prevention and control, the progress of work in all localities is regularly supervised and made public. Interview accountability for areas where work responsibilities are not implemented, project progress is lagging behind, and ambient air quality is unqualified.

　　3. Strictly punish environmental violations. Improve on-site inspections, cross-enforcement, joint enforcement, spot checks and other environmental law enforcement methods, strengthen law enforcement linkage and information sharing between environmental protection departments and relevant departments, and improve the cooperation mechanism for investigating and handling environmental violations. Highlight the key points of supervision, supervise and supervise key environmental issues in various places, and vigorously rectify air pollution. Resolutely ban unlicensed enterprises such as small refineries and small boilers, and focus on cracking down on behaviors such as excessive emissions of heavily polluting enterprises, irregular management of construction dust, and production and sales of unqualified oil products. Explore the evaluation of enterprise environmental credit and improve the construction of environmental credit system.

　　4. Improve the convergence mechanism of law enforcement. Strictly implement the Interpretation of the Supreme People’s Court and the Supreme People’s Procuratorate on Several Issues Concerning the Application of Laws in Handling Criminal Cases of Environmental Pollution (Fa Shi [2013] No.15), establish a law enforcement linkage mechanism between environmental protection departments and public security departments, improve the transfer, acceptance and filing of criminal cases of environmental pollution, and the consultation and supervision system for major cases, increase the comprehensive punishment for major environmental crimes according to law, severely punish illegal and criminal acts of environmental pollution, and further enhance the deterrent force of environmental law enforcement.

　　Third, safeguard measures

　　(ten) improve the coordination and early warning emergency mechanism.

　　1. Improve the coordination mechanism for prevention and control. Further improve the work mechanism of joint prevention and control of air pollution in the province and the regional cooperation mechanism of Guangdong, Hong Kong and Macao, hold regular meetings on air pollution prevention and control in the province, coordinate and solve major environmental problems and cross-city air pollution disputes, and guide all localities and relevant departments to establish unified air pollution prevention and control policies. All localities should establish a consultation and cooperation mechanism for joint prevention and control of air pollution with unified planning, unified monitoring, unified supervision, unified evaluation and unified coordination. Cities in the Pearl River Delta region should strengthen coordination and linkage to solve outstanding problems such as fine particles and ozone. All relevant departments should work together to fully support the prevention and control of air pollution according to their respective responsibilities.

　　2. Improve the monitoring and early warning system. Improve the province’s atmospheric environmental monitoring network, and all state-controlled atmospheric monitoring stations in cities above prefecture level will carry out monitoring as required. Environmental protection and meteorological departments should strengthen cooperation, establish and improve the monitoring and early warning system of heavy air pollution, and jointly promote air quality forecasting. Conduct early warning drills for heavy pollution weather on a regular basis, and complete the construction tasks of monitoring and early warning systems for heavy air pollution in the provinces, the Pearl River Delta region and Guangzhou before the end of 2014, and other cities in the Pearl River Delta region will complete the construction tasks of monitoring and early warning systems for heavy air pollution before the end of 2015.

　　3. Improve the emergency response mechanism. The provincial environmental protection department should take the lead in formulating and organizing the implementation of the emergency plan for heavy air pollution in the Pearl River Delta region as soon as possible, and announce it to the public in a timely manner. In order to go public at all levels, it is necessary to formulate emergency plans for heavy air pollution in the region, clarify the responsible subjects, organizations, job responsibilities, early warning and response procedures, safeguard measures, etc., and announce them to the public in a timely manner. Local governments should incorporate the emergency treatment of heavy air pollution into the emergency management system of local emergencies and implement the responsibility system of the main person in charge. Establish and improve the regional air pollution prediction and early warning mechanism of monitoring and forecasting-expert consultation-reporting for approval-response implementation. When heavy pollution weather is predicted, local governments should take emergency response measures in time and organize all relevant parties to carry out their work as required.

　　(eleven) improve the local regulations and technical standards system.

　　1. Improve laws and regulations. Revise the Measures for the Administration of Pollutant Discharge Permit in Guangdong Province in a timely manner, accelerate the formulation of the Regulations on the Prevention and Control of Air Pollution in Guangdong Province, improve the systems of total control, pollutant discharge permit, emergency warning and accountability, realize the organic connection between administrative law enforcement and criminal justice, and improve the compensation system for environmental pollution damage according to the principle of "whoever pollutes is responsible and pays more for more emissions".

　　2. Improve the standard system. Strengthen the preparation and revision of local standards in Guangdong Province, speed up the revision of the emission limit standards of atmospheric pollutants in Guangdong Province, formulate the limit standards of harmful substances in low-sulfur loose coal and products, coatings, inks and other products, clarify the emission standards of atmospheric pollutants for biomass briquettes and the emission standards of volatile organic compounds in key industries, establish the emission accounting system of volatile organic compounds in key industries, and strengthen the hard constraints of energy consumption and safety standards.

　　3. Strengthen technical support. Strengthen the basic research on haze, ozone formation mechanism, source analysis, migration law, etc., and carry out the study on the exposure-response relationship between air pollution and population health. Support the construction of Guangdong National Key Laboratory of Environmental Protection and encourage environmental protection enterprises to build engineering technology research and development centers and engineering research centers (laboratories). Actively develop products and equipment for desulfurization and denitrification, high-efficiency dust removal, volatile organic compounds control, diesel engine (vehicle) emission purification, environmental monitoring, etc., and popularize a number of advanced and practical technologies to solve regional compound air pollution problems.

　　(12) Improve environmental and economic policies.

　　1. Improve the price system of resources and environment. Give full play to the leverage of resource prices and guide enterprises to produce green and consume green in society. Study and formulate differentiated and stepped resource price policies, and implement electricity price support policies for existing thermal power units that have adopted new technologies to transform dust removal facilities. Implement the policy of high quality and good price for oil products, and encourage oil refining enterprises to accelerate the pace of upgrading oil products.

　　2. Increase fiscal and taxation support. At the provincial and local levels, the funds for pollution prevention and control are listed as a whole, and the forms of "replacing compensation with awards", "promoting prevention with awards" and "promoting governance with awards" are adopted to support the prevention and control of air pollution. We will fully implement the preferential fiscal and taxation policies for contracted energy management, and actively explore the integrated franchise mode of investment, construction and operation of pollution control facilities. We will improve the support policies for the collection and emission reduction of sewage charges, and gradually levy sewage charges for volatile organic compounds, dust from construction sites, gas stations and operating catering fumes.

　　3. Innovative environmental protection financial policies. Establish green credit, green securities and environmental pollution liability insurance systems, incorporate corporate environmental information into the bank credit information system, and strictly restrict environmentally illegal enterprises from obtaining loans or listing financing. Accelerate the pilot work of paid use and trading of emission rights and carbon emission rights such as sulfur dioxide.

　　(13) Improve the participation mechanism of the whole society.

　　1. Timely disclosure of environmental information. Since 2014, the provincial environmental protection department will regularly publish the air quality status and ranking of cities at or above the local level every month, and all state-controlled and provincial-controlled air quality monitoring stations in the province will release air quality information to the public in real time. All localities should establish a compulsory disclosure system for environmental information of enterprises in heavily polluting industries, promptly and proactively publish information such as environmental impact assessment approval of new projects, sewage charges, supervision and law enforcement penalties, pollutant discharge of key enterprises, operation of pollution control facilities, and regularly publish environmental credit rating results of key pollution sources.

　　2. Mobilize the whole people to participate. Actively carry out various forms of publicity, education and training, popularize scientific knowledge of air pollution prevention and control, advocate civilized, economical and green consumption patterns and living habits, and improve the enthusiasm of the public to participate in atmospheric environmental protection. Encourage the public to supervise and report air pollution by opening a hotline for reporting and hiring special supervisors for air pollution prevention and control, and support environmental protection social organizations and environmental protection volunteers to carry out social supervision activities.

　　Municipal governments at or above the local level shall, in accordance with this action plan, pay close attention to formulating specific implementation plans for the region, decompose and implement tasks, and submit the progress of air pollution prevention and control work in the previous year to the provincial government before March 31 each year.

Original Zhiyuan Xin Zhiyuan Xin

Zhiyuan Xin reports.

Editor: editorial department

[Introduction to Zhiyuan Xin] Grok of xAI opened its source as scheduled after seven days! Open the code behind Grok and let Musk slap his face at OpenAI. There are 8 MOEs with 314 billion parameters, and the weight structure is fully open. As soon as the project is launched, it has already snapped up 6k stars on GitHub.

When it comes to doing it, Grok of Musk xAI is really open source as scheduled!

Just now, xAI officially released the weight and architecture of the 314 billion parameter hybrid expert model Grok-1.

With a parameter of 314 billion, Grok-1 has become the largest open source LLM so far, four times that of Llama 2.

At present, xAI has not disclosed more information about Grok-1.

The information released by official website is as follows-

-The basic model is trained on a large amount of text data and has not been fine-tuned for any specific task.

The MoE of the-314B parameter has a weight of 25% that is active on a given token.

-In October, 2023, xAI started training from scratch using a custom training stack based on JAX and Rust.

Once online GitHub, Grok snapped up 6k stars and 586 Fork.

Project address: https://github.com/xai-org/grok-1.

Musk did not forget to ridicule OpenAI, "Tell us more about the" open "part of OpenAI …"

The new york Times commented that the original code behind the open source Gork is an upgrade of the future battle that the richest man in the world controls AI.

Will open source make technology safer or will it make it more abusive?

Musk, an "open source supporter", set an example and got involved in this heated debate in the AI community, and gave the answer with actions.

Xiao Zha also commented on Grok just now. "It didn’t really impress people. There are too many parameters of 314 billion. You need a bunch of H100, but I have already bought it."

A magnetic chain, the world’s first largest model open source.

This time, xAI open source Grok-1 is licensed by Apache-2.0, so users can freely use, modify and distribute the software.

The repository contains JAX sample code for loading and running the Grok-1 open source weight model.

Users need to download checkpoint, put the ckpt-0 directory in checkpoint, and then run the following code to test:

pip install -r requirements.txtpython run.py

This script will load the checkpoint and the samples in the model on the test input.

Because the model is large and the parameters reach 314B, a computer with enough GPU memory is needed to test the model with sample code.

Moreover, because the implementation efficiency of MoE layer in this repository is not high, this implementation is chosen to avoid the need to customize the kernel to verify the correctness of the model.

Through the Torrent client and the following magnetic link, you can download the weights.

magnet:? xt=urn:btih:5f96d43576e3d386c9ba65b883210a393b68210e&tr=https%3A%2F%2Facademictorrents.com%2Fannounce.php& tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce

More details

Andrew Kean Gao, a Stanford researcher, browsed model.py and introduced more information about the architecture of Grok. There are no additional clauses for the 314 billion parameters.

8 mixed experts (2 active experts), 860B active parameters. It uses rotation embedding instead of fixed position embedding.

-tokenizer vocabulary: 131,072 (similar to GPT-4) is equivalent to 2 17.

-Embedded size: 6144(48*128)

-Transformer layer: 64 (each layer has a decoding layer: multi-head attention block and density block)

-Key size: 128

Multi-head attention module: there are 48 query headers and 8 key values.

Dense block (dense feedforward block):

-Width factor: 8

-The hidden layer size is 32768.

Each token selects 2 out of 8 experts.

The embedding size of the rotation position is 6144, which is meaningful, and it is the same as the input embedding size of the model.

-Context length: 8192 token

-Accuracy: bf16

Finally, attach a summary map.

Netizen: Open source battle is coming.

The AI community is already boiling!

The technical community points out that the highlight of Grok is the use of GeGLU and normalization method in the forward feedback layer, and the use of interesting sandwich norm technique.

Even OpenAI employees have expressed their strong interest in Grok.

Jim Fan, a senior scientist in NVIDIA, said, "The largest open source model in history was trained by a world-class team and released through the magnetic chain Apache 2.0.

314B parameter, mixed expert model (8 experts and 2 active). Even the active parameter scale (86B) exceeds the largest Llama model. I can’t wait to see the benchmark results and what kind of applications people can build with it. "

Sebastian Raschka, an AI researcher, said that Grok is more open-source than other open-source modular models that usually have restrictions on use. However, it is less open source than Pythia, Bloom and Olmo, which provide training code and reproducible data sets.

Boris Dayma, the founder of Craiyon, analyzed the code of Grok-1 in detail.

Netizen indigo said that in order to "understand the universe", it seems that the xAI team deliberately set the parameter as "pi 314B", which is the largest open source model at present. It is expected that Llama 3 will join Grok’s open source battle in June this year.

After Grok opened the source, a big wave of fine-tuning is coming.

The first generation Grok has surpassed Llama-2-70B.

In November, 2023, xAI launched its first generation of big language model, Grok, and formally joined the big model war.

At that time, Grok used Twitter as part of the "Premium+" subscription service, with a monthly fee of $16.

XAI said that Grok’s design was inspired by The Hitchhiker’s Guide to the Galaxy, which can answer almost all questions and help people pursue understanding and knowledge regardless of background or political stance.

Grok’s original version, Grok-0, had 33 billion parameters, and then xAI introduced Grok-1, which was improved several times to support the Grok chat robot on X.

According to the data released by xAI, in a series of benchmark tests such as GSM8K, HumanEval and MMLU, Grok-1 outperformed LLMA-2-70b and GPT-3.5, although it was far from GPT-4.

At that time, Grok was not only able to handle the user content generated in real time on the X platform, but also had a little sense of humor, which injected a little vitality into the simple AI.

While providing information about the latest hot events (whether political or sports), it can also be clever and even occasionally sarcastic.

Why did Musk choose open source?

After mocking OpenAI as "CloseAI" several times, Musk really chose to open his own big model.

Of course, there must be commercial considerations behind this.

As a market leader, OpenAI has no reason to open source the model code behind ChatGPT.

Now, by releasing Grok’s code, Musk firmly rooted himself in the latter camp. This decision may make his xAI surpass Meta and Mistral AI.

Llama’s open source has brought many benefits to Meta, and almost made Xiaozha climb out of the quagmire of the meta-universe.

Mistral AI, which is just a small start-up, is also famous for its open source strategy and is recognized by the industry as "OpenAI in Europe".

The open source version may encourage developers and potential customers to adopt their own models more quickly, which actually plays a marketing role.

The feedback and improvement from the developer community on the open source version of Grok may also help xAI to speed up the development of new versions, which can choose to open source or keep exclusive rights.

For example, like Mistral, it promises to continue to release open source versions while retaining the most advanced models for paying customers.

Musk has always been a supporter of open source technology. Even Tesla has opened the source code of some parts of the car, and his social media platform X has published some algorithms for content ranking.

"There is still work to be done, but this platform is by far the most transparent, truth-oriented and not a high threshold platform," Musk said today in response to comments on the open source X recommendation algorithm.

Although OpenAI is still far ahead in the AI field, the war between open source and closed source is far from over.

Should the AI model be open source? Some people think that this powerful technology must be protected from intruders, while others insist that the advantages of open source absolutely outweigh the disadvantages.

As a market leader, OpenAI has no reason to open source the model code behind ChatGPT.

Now, by releasing Grok’s code, Musk firmly rooted himself in the latter camp.

This decision may enable his xAI to finally surpass Meta and Mistral AI.

The "Little Book-turning Party" is a sub-column of the "Book-turning Party" in The Paper: reading the knowledge in books in a well-documented way.

In the hit drama Ode to Joy, almost all the protagonists use Apple phones, except Qiu Yingying, who seems to have a replacement Android phone. We don’t know whether Apple also paid the advertising fee for this play, but it’s not surprising if there are a group of people around you who are using Apple phones, and everyone may encounter one or two "fruit fans" who are obsessed with Apple products and act as "free salesmen".

Martin Lindstrom of marketing guru said in his "brand brainwashing" that "fruit powder" is actually similar to Christians.

His exact words are as follows:

As we all know, no brand can become a cult-like, almost religious worship brand like Apple (in fact, in an experiment I did for my last book, when I studied the brains of Apple fans with functional magnetic resonance imaging, I found that their brain activities are similar to those of Christians), and peer pressure is the core of many Apple strategies. One of the strategies is "early recruitment", in other words, it is to sell it to children aged 13-17. This marketing activity is so effective that about 46% of the children of this age now own an iPod, and the product that children talk about most among themselves is the iPod, and a questionnaire survey shows that 82% of all high school students with portable music players use the iPod.

Once these children entered the university, Apple began to openly "recruit", hired college students to become "Apple campus representatives" and turned the whole university bookstore into a mini-Apple store. One job advertisement said, "This is a great opportunity to be an Apple spokesperson and have some fun." The job description includes hosting workshops, organizing activities, and establishing good relations with students, faculty and students’ parents. The most important thing is, "You will cooperate with the Apple team to implement marketing projects on campus, including promoting sales and raising the awareness of Apple products … We need a leader who can inspire peers and cooperate with student organizations."

This copy is very clever: who doesn’t want to think of himself as a leader, a trendsetter and a person who can inspire his peers? I would like to add that if you often go to the movies, you may think that people all over the world use Apple products-this is a victory that combines product implantation and peer pressure. In 2009, almost half of Hollywood movies-about 46%-featured Apple or Apple products. Although it is generally believed that this behavior does not involve money transactions, there is no better way to expose advertisements and brands.

Well-documented:

Martin thinks that Apple has obviously taken advantage of people’s psychology: it succumbs to some potential "peer pressure", that is, people want what others want. And the more obvious the needs of others are, the more we want what they have. According to Martin, this is what advertisers and marketers have known for a long time.

Black Friday and "11.11" snapping up may also take advantage of this psychology:

This fear of’ if someone else takes it, we will miss it’ drives fanatics to queue up at 4 am, just to get the latest iPad2 or a pair of UGG wool boots with rare colors, and this is why a bargain hunter was trampled to death outside Wal-Mart on Long Island on a black Friday a few years ago. If you bid for goods on eBay, you are likely to fall victim to this trap unconsciously. If there is only one product (for example, there is only one penguin tea set in the world), then the fear that’ others may easily get a set of mugs with orange beaks’ will drive people to raise the bid price exponentially-and pay a price far beyond the value of the product.

Martin thinks that the bestseller list also takes advantage of "peer pressure":

To know how much strangers’ preferences and purchases affect our decisions, just look at the leaderboard phenomenon. Imagine you walk into a large chain bookstore as big as a football field. Faced with a large number of choices, it is still quite risky to spend $27.99 on a novel or memoir that you later find hard to read. But wait, what’s on the independent shelf on your right? This week’s "Best-selling List of The New York Times", including fiction and non-fiction, has more than 20 books in total. Subconsciously, you think, "If so many people buy this book, it must be a good book", and then you think, "If so many people are reading this book, won’t it be out of date if I don’t read it?" Now, you not only avoid the pain of going through four floors and not knowing how to start, but also get the recognition of your peers who buy books. This is not a happy coincidence in the publishing industry. In fact, although publishers want you to believe the contents of the list, the main reason why the best-selling list existed at first was not only to track sales, but also to make us think that these books were "pre-approved"—in other words, if we didn’t read the books that everyone else was reading, we would be ill-educated, unable to keep up with the trend, and would be excluded from the national language theory.

Well-documented:

More interestingly, Martin found that even if consumers are "used", they still think that their buying behavior is rational:

Of course, we don’t always realize that the perceived popularity of goods affects our preferences. Recently, I asked 10 female fans in louis vuitton in a focus group: "Why do you like this brand so much?" Everyone mentioned the quality of zippers, leather and brand immortality. I am doubtful about that. So we scanned the brains of these 10 women with functional magnetic resonance imaging. Every time we show them pictures of louis vuitton products, the "Brodmann area 10" in the brain will be lit up, which will be activated when people see something they think is "cool". These women rationalize their buying behavior and tell themselves that they like this brand because of its high quality, but their brains know that they actually make choices because they are’ cool’. Even the brain can’t stand the fact that we are excluded, which seems to indicate that whether it is "hot" songs, "that" gifts or "trendy" designer handbags, what we finally buy has nothing to do with what we want, but more of what we think we should.

But the most interesting thing is that Martin found that even marketers themselves will fall into this trap:

For example, the planner of every advertising company I know (in most European advertising companies, this position is to do consumer research) has a beautiful Moleskine leather notebook. This was not sent when they joined the company; It has become an unwritten rule that every planner of an advertising company must own one and use it. If you don’t, it means that you are isolated and not an insider.

Book shadow:
