Introduction | It may also be related to the fortune of China Zhijia.

How many days does an entrepreneur need from crying to laughing? For Xia Yiping, CEO of Extreme Vietnam, 13 days.

First, the sales of Extreme Yue 01 made him cry.

Before the Chengdu Auto Show on August 28, Xia Yiping burst into tears in the interview: "I sold more than 200 units in January and more than 100 units in February, and I feel very uncomfortable myself."

His reflection is that there are some "anti-human designs" in Extreme Yue 01 that have aroused users’ dissatisfaction, such as half steering wheel, screen shifting and key steering. Anyone with a discerning eye will know at a glance that this is based on Tesla’s design.

Xia Yiping believes that there is no problem with these designs themselves. The problem is that there is very little system power and fame of Tesla, so it is difficult to be accepted by the public. This reflection is correct.

Che Jujun also expressed similar concerns when he test-drove Extreme Yue 01 in November 2023. The accompanying public relations partner naturally explained: Is Huan’s new Model 3 designed in this way?

Che Jujun said seriously: There are some things that Tesla can do, but other brands may not be able to do.

It seems that it took more than half a year to finally understand this truth.

Summer tears, do not rule out the composition of flow. But half a month later, in the Capital Gymnasium, when the second car, 07, went on the market, his joy and heroism should be true.

Because in the past August, the sales volume of Extreme Vietnam 01 suddenly rose to 2,147 vehicles, equivalent to 10 times that at the beginning of the year. This sales volume is not good for mature car companies, but it can be said that it has come back to life for the extremely faltering start, "now it is a step from the beginning."

The reason or as Xia Yiping said, he has never lost the trust and support of shareholders.

For Apollo Zhijia, behind it is Baidu’s 150 billion investment in 10 years; For the SEA architecture, Geely has invested 20 billion yuan in five years. Both software and hardware are top resources in the industry. The more temporarily sleepy, it may just take time. Therefore, even when only 147 sets were sold every month, Li Yanhong and Li Shufu didn’t publicly criticize Xia Yiping as Zhou Hongyi publicly criticized Zhang Yong.

On the other hand, the ultimate innovation really takes time to be accepted by the market.

Extremely, the manual operating parts in the car are made extremely simple, in order to meet the era of fully automatic driving that will be realized soon. If the car is mainly driven by machines, why do you need so many physical keys? This is a bottom logic of extreme transcendence.

Che Jujun has some reservations. Last November, I tried the pure visual intelligent driving of the ultra-01, and it did have many advantages. There were not many manual takeover times in the whole trip. But it is a few takeovers that are full of risks. For example, on the Jiamin viaduct, we walked in the rightmost lane, and the lane ahead was suddenly interrupted due to road construction. The pure vision system did not perceive the change of the end and the sign of the isolation pier, and continued to go straight at a constant speed, so it could only be manually intervened.

On August 28th, at the pre-sale meeting of Extreme Yue 07, Xia Yiping announced that Extreme Yue 07 will be equipped with ASD for the first time. It is also announced that Extreme Vietnam is the first electric vehicle brand in the world to apply the L4-class self-driving model.

The full name of ASD is: Apollo Self Driving, Apollo Autopilot. That is to say, machine driving is the mainstay. This name, and Tesla’s FSD(Full Self Driving) fully automatic driving, has the same effect. Xia Yiping made no secret of his ambition to mark Tesla: from beginning to end, we wanted to have a fight with Tesla.

He further declared that ASD knows more about China road than Tesla FSD because he was born in China and grew up in China.

Will the renamed ASD be a qualitative improvement over the extremely smart driving one year ago?

This year, Baidu’s smart driving has indeed undergone many changes. For example, unmanned taxis powered by Apollo have been put into operation in several cities in China, especially in Wuhan, which caused a sensation as soon as it appeared. People even worry that this advanced intelligent driving will rob the network car and taxi drivers of their jobs.

The data shows that Apollo’s "Radish Run" unmanned taxi has completed a total of 6 million travel services, and its autonomous driving operation scale ranks first in the world.

In terms of computing power, Apollo cloud computing power has exceeded 5.5 EFlops. Based on this, Extreme Yue can carry out AI cluster training to realize rapid iteration of intelligent driving model, and the cycle can even be as short as weeks.

This is an advantage of Baidu’s deep cultivation of autonomous driving for ten years, and it is also an advantage of China’s huge market and rich scenes. At the same time, it is probably one of the reasons why Xia Yiping was able to smile when he went public in Extreme Vietnam 07.

Second, the prospect of extreme auto-driving made him laugh.

On the evening of September 10th, the Capital Gymnasium ushered in its first new car launch conference-Extreme Yue 07. This is a medium-sized and large-sized pure electric car, and it is the second car under the banner of Extreme Vietnam, with a limited-time preferential price of 199,900.

There are many bright spots in Extreme Yue 07, such as design. But Xia Yiping passed by, and then went straight to the point: two days later, he will drive the Super Yue 07 with ASD to challenge the non-standard pontoon bridge.

Sure enough, on September 12th, Xia Yiping sat in an extremely cross 07, opened the ASD and passed a pool in Maling Mountain, xinyi city. It is worth noting that the pontoon bridge on the pool is temporary, and it is not on the map at all. This move wants to prove that the pure vision scheme can achieve high-order intelligent driving without lidar and high-precision map.

The test project of crossing the pontoon bridge was carried out five times, including night working conditions. Xia Yiping’s conclusion is that one pass is accidental, and five safe passes are inevitable. We are full of confidence in ASD’s intelligent driving.

Therefore, he dared to shout out at the press conference two days ago: "Extreme Yue 07 is the most intelligent car on the planet". Of course, in order to avoid regulatory risks, what is printed on the screen is: _ _ _ _ smart car on the planet.

Then, Xia Yiping introduced some highlights on the hardware of Extreme Yue 07.

▲ Image source: Cheju.com

▎ Extreme design. I wonder if its designer is Virgo? In order to make the front of the Extreme Yue 07 longer and look more like a rear-drive performance car, its A-pillar moved back by 65 mm.. The price is 300 million yuan.

You know, it only sold 7,000 cars in total. Even if a car earns 20,000 with a gross profit of 10%, the total gross profit is only 140 million. It feels like the boss worked hard to support his family, and all the wages he earned were taken away by his parents and doubled, and he turned to do plastic surgery for his second child. Fortunately, the face value of Extreme Yue 07 is really handsome.

▎ Extreme performance. Based on Geely SEA architecture, equipped with 800V dual motors, the total power is 530kW, the peak torque is 653N·m, the maximum speed is 230km/h, and the acceleration of 100 kilometers is 3.5 seconds, which is 0.4 seconds faster than the basic version of 911.

By the way, the performance of the Extreme Yue 07 dual-motor version is almost the same as that of the Lectra Z10, but the speed is slightly lower.

▎ Extreme endurance. Extremely over 07 three models, equipped with three kinds of batteries. The low-grade lithium iron phosphate battery is 71.4 degrees, which comes from honeycomb energy; The middle distribution is 100-degree ternary lithium battery, which comes from Times Geely; High match is 93.4-degree ternary lithium battery, from Contemporary Amperex Technology Co., Limited Kirin battery.

The CLTC life of three batteries is very easy to remember: 660km, 880km and 770km.

The most cost-effective is the middle match, which can have a battery life of 880km as long as it is 219,900. The concept is that from Shanghai to Beijing, only one charge is enough.

In order to prove the strength of the battery, Zeng Yuqun was also invited to the scene at the press conference of Extreme Yue 07.

▎ Extreme security. Gao Huan, CTO of Contemporary Amperex Technology Co., Limited, came to the stage to explain the battery technology. He gave a landmark conclusion: At present, the battery failure rate in Contemporary Amperex Technology Co., Limited has been reduced to 1/100 million, which is equivalent to the change from PPM to PPB, which is three orders of magnitude lower, or the safety has been improved by 1000 times.

The Kirin battery carried by the ultra-Yue 07 High-Match uses Contemporary Amperex Technology Co., Limited’s original double-large-surface water-cooling technology, aviation-grade thermal insulation pad and specially controlled non-diffusion technology, and a bulletproof coating is sprayed on the bottom of the battery pack, which improves the waterproof, wear-resistant and impact-resistant capabilities. It is said that if you wrap eggs with it, it will not break when you fall from more than ten floors.

The live video shows that when the Kirin battery pack was shot, bullet holes only appeared on the outermost side of the bottom guard plate, and the bottom guard plate itself was not penetrated, and the bullet finally got stuck in the bulletproof coating. Stand still for 2 hours, without fire or smoke.

▎ Extreme energy consumption. Permanent magnet synchronous motor adopts 800V silicon carbide technology, uses the thinnest silicon steel sheet and X-pin winding in the world, and the comprehensive efficiency of electric drive is as high as 92%. This makes the minimum power consumption only 12.4 degrees/100 kilometers.

According to Xia Yiping, the BMW 5 Series costs more than one yuan to run a kilometer, and it costs only 3.7 cents to run a kilometer over the 07. The premise is to use home-filled piles to charge at night. Take Shanghai as an example. After 22: 00, the electricity charge is 0.33 yuan/kWh, and it takes 33 yuan to charge 100 kWh. If you run 880km, it is only 3.7 cents.

The problem is that CLTC’s battery life of 880km does not mean that it can actually run so much. According to the spring and autumn period, you can run 700km, which is 4.7 points/km. Not bad either.

▎ Extreme energy supplement. Also thanks to the 800V high-voltage system, the battery charging rate of Extreme Yue 07 reached 5C, and the charging time of 10%-80% was only 10 minutes. In the same charging method, it takes 10.5 minutes for the second-generation BRICS battery of Krypton 007 and 15 minutes for the first-generation BRICS battery of Lectra Z10.

Xia Yiping also gave a specific value: charging for 10 minutes can increase the battery life by 600km, which is equivalent to one kilometer per second. Che Jujun thinks that this premise is to use V3 super fast pile filling. Take krypton V3 pile as an example, its peak power is 800kW and its maximum current is 800 A.. To get close to this kind of power, there are probably only the latest charging piles of Wei Xiaoli and Hua Xiaote, and the power of most charging piles on the market is about 100kW.

Che Jujun measured the charging efficiency of the high-speed service area this summer. Taking Yinhe E8 as an example, charging 260km in 15 minutes is the peak level, and the median is 200km. Some overcharging stations in urban areas are even lower, about 140km.

Despite some praise and ideal working conditions, the product strength of Extreme Yue 07 is still quite powerful. Even when Che Jujun watched the Z10 in a Linke store, the sales said: It’s not Xiaomi SU7 that can compete with Linke Z10, but extremely Yue 07.

It should be a kind of recognition to be praised by competitors behind their friends. No wonder Xia Yiping smiles more naturally.

When other car companies are still discussing whether to cooperate with Huawei to drive intelligently and whether to hand over their souls, Extreme Yue was born with a first-line soul, a first-line body, and a first-line face value: Baidu provided Apollo with intelligent driving, Geely provided the vast structure of SEA, and spent 300 million yuan on plastic surgery to properly build a Gao Fushuai.

The key is to worship Tesla as a teacher and concentrate on pure visual intelligent driving.

I feel that Extreme Yue 07 has filled all the buff that China car companies can think of. If it is not sold well again, it is not surprising that Xia Yiping is crying. A variable, still time. FSD’s entry into China is imminent. Before catfish enter the pond, the native fish must practice their internal skills, otherwise it will not look good if they are really eaten in a mess. At this time, the polar cross 07 may become a leading fish. It can only be done well, otherwise there will be fewer opportunities for so many drivers in Wuhan to reduce.

As for the sales volume, the news is that 5000 vehicles were ordered within 48 hours of listing. It can’t be compared with the 88,000 vehicles in 24 hours of Xiaomi SU7, or even the 5,000 vehicles in 24 hours of Lexus Z10, but it is very good for a new brand that once sold more than 100 vehicles a month.

The big deal is that Baidu will do it again, and let radish run and purchase a batch of extremely fast.

　　Not long ago, statistics released by the National Bureau of Statistics showed that the total national grain output in 2021 was 1,365.7 billion Jin, an increase of 26.7 billion Jin over the previous year, with an increase of 2.0%. The annual grain output reached a new high and remained above 1.3 trillion Jin for seven consecutive years. The harvest in the first year of the "14th Five-Year Plan" was hard-won. According to the data of the third national land survey released in 2021, China’s cultivated land area is 1,917.9 million mu, but the quality of cultivated land is generally not high, of which 1/3 belongs to high-standard farmland, and 2/3 is low-yield farmland that depends on the weather. Therefore, ensuring food security is an eternal topic. Biological breeding technology is an important support for developing modern seed industry and solving food security problems.

　　New focus of international science and technology competition

　　Biological breeding is a process of cultivating new biological varieties by using the methods and principles of genetics, cell biology, modern bioengineering technology, transgenic, gene editing, whole genome selection and synthetic biology. Biological breeding technology embodies the latest achievements and applications of contemporary biological science research. Since the 20th century, biological breeding technology has gone through three leaps, namely, the "first green revolution" in 1950s, the hybrid rice technology in 1970s, and the molecular breeding stage since 1990s. Today, biological breeding has taken another big step forward, and advanced countries in the world have entered the era of intelligent design breeding based on biological big data technology from molecular breeding.

　　At present, seizing the commanding heights of biological breeding technology and its industrial development has become a major strategic choice for all countries in the world to enhance the core competitiveness of agricultural industry. The application of genetically modified crops has been accelerated, which has promoted the transformation of agricultural production mode. Especially since the commercial planting of transgenic crops in 1996, the variety of crops has expanded from 4 kinds of corn, soybean, cotton and rape to 32 kinds of potatoes, alfalfa, eggplant, sugarcane and apples. The planting area increased from 25.5 million mu to 2.86 billion mu, an increase of 112 times. The number of planting countries has increased from 6 to 29, and another 42 countries have approved the import application. The number of countries that have commercialized genetically modified crops in the world has reached 71.

　　In 2019, 74% of soybeans, 31% of corn, 79% of cotton and 27% of rapeseed in the world’s major crop planting area are genetically modified varieties, and 99% are insect-resistant and herbicide-tolerant. It is precisely because of the application of insect-resistant and herbicide-resistant traits that the competitiveness of genetically modified crops such as corn and soybeans in terms of cost, price and quality has been improved, and the trade share of genetically modified agricultural products in the international agricultural products market has been greatly improved. In 2019, the global soybean and corn trade accounted for 95% and 70% respectively.

　　In recent years, with the completion of genome sequencing of many important species, genomics research has developed rapidly, and countries and multinational companies all over the world have stepped up their efforts to carry out basic research on gene function in order to compete for relevant intellectual property rights. In addition, the deep integration of transgenic technology with gene editing, synthetic biology and whole genome selection technology has promoted the development of biological breeding in the direction of systematization and integration of exogenous gene transfer, endogenous gene editing, metabolic pathway reconstruction and even artificial design and synthesis.

　　The development of technology has also promoted the upgrading iteration of biological breeding products. Taking transgenic products as an example, it has expanded from single insect resistance and herbicide tolerance to complex traits. New transgenic crops are resistant to many pests and herbicides, and some of them also have drought resistance, improved quality, high yield and high efficiency. At present, more than 70 kinds of gene editing products, such as high oleic acid soybean, disease-resistant rape and blue ear disease-resistant pig, have been launched all over the world.

　　Included in the strategic plan of China’s major scientific and technological development

　　In the international scientific and technological competition of biological breeding, China has actually begun to lay out its layout very early. As early as the middle and late 1980s, the National High-tech Research and Development Plan (863 Plan) included functional gene cloning, transgenic operation and breeding technology of new varieties of genetically modified organisms. The national key basic research and development plan (973 plan) also gives key support to the safety evaluation and risk control of genetically modified organisms; In 1999, the Ministry of Science and Technology and the Ministry of Finance jointly launched the "National Special Project on Research and Industrialization of Genetically Modified Plants". In 2006, the Central Committee of the Communist Party of China and the State Council approved the Outline of the National Medium-and Long-term Scientific and Technological Development Plan (2006-2020), which listed the cultivation of new varieties of genetically modified organisms as one of the 16 major national science and technology projects. In 2008, the major transgenic project was officially launched, with the goal of obtaining a number of functional genes with independent intellectual property rights and important application value, cultivating a number of new varieties of major transgenic animals and plants with resistance to pests and diseases, stress resistance, high quality, high yield and high efficiency, and improving the overall level of research and industrialization of agricultural genetically modified organisms.

　　In 2009, the No.1 Document of the Central Committee called for speeding up the major scientific and technological projects for the cultivation of new varieties of genetically modified organisms, integrating scientific research resources, intensifying research and development, cultivating a number of new varieties of genetically modified organisms with disease resistance, stress resistance, high yield, high quality and high efficiency as soon as possible, and promoting industrialization; In the same year, the State Council issued "Several Policies for Accelerating the Development of Bio-industry", which clearly stated that it was necessary to speed up the cultivation of bio-industry into a pillar industry in the high-tech field and a national strategic emerging industry. In 2010, the No.1 Document of the Central Committee requested to continue to implement the major scientific and technological projects for cultivating new varieties of genetically modified organisms, pay close attention to the development of functional genes and new varieties of organisms with important application value and independent intellectual property rights, and promote the industrialization of new varieties of genetically modified organisms on the basis of scientific evaluation and legal management.

　　In 2015, the No.1 Document of the Central Committee called for strengthening the research, safety management and scientific popularization of agricultural genetically modified organisms. In 2016, the No.1 Document of the Central Committee requested to strengthen the research and development and supervision of agricultural genetically modified technology and promote it carefully on the basis of ensuring safety. In 2020, the No.1 Document of the Central Committee called for strengthening agricultural biotechnology research and development. China’s "Fourteenth Five-Year Plan" proposes to implement a number of forward-looking and strategic national major scientific and technological projects aimed at frontier fields such as artificial intelligence, quantum information, integrated circuits, life and health, brain science, biological breeding, aerospace science and technology, and deep sea, which means that the development of biological breeding has risen to the height of national strategy.

　　In 2021, the No.1 Document of the Central Committee once again stressed that it is necessary to respect science, strictly supervise and promote the industrialized application of biological breeding in an orderly manner. The 20th meeting of the Central Committee for Comprehensively Deepening Reform held in the same year also emphasized that the seeds are the foundation of agricultural modernization, so it is necessary to promote the national seed industry, raise the safety of seed sources to a strategic height related to national security, and concentrate on solving problems, filling shortcomings, strengthening advantages and controlling risks, so as to realize the self-reliance and self-reliance of seed industry science and technology and the independent control of seed sources.

　　Realize the national seed industry’s scientific and technological self-reliance

　　Up to now, biological breeding has been included in one of the major strategic directions of China’s scientific and technological development, and has formed an innovative pattern of independent genes, independent technologies and independent varieties, and has bred more than 70,000 main crop varieties, which basically meets the needs of agricultural production.

　　On the one hand, the industrial application of transgenic insect-resistant cotton and disease-resistant papaya in China has achieved remarkable results, especially with the support of major transgenic projects, 197 new varieties of insect-resistant cotton have been bred, with a cumulative promotion of 510 million mu, a reduction of 650,000 tons of pesticides and a cumulative increase of 65 billion yuan.

　　On the other hand, China’s genetically modified soybeans and corn have been industrialized, and four insect-resistant and herbicide-tolerant genetically modified corn have obtained production and application safety certificates. Insect-resistant transgenic maize new strain has an insect-resistant effect of more than 95%, which effectively reduces pesticide consumption and aflatoxin pollution. Three herbicide-resistant transgenic soybeans in China have obtained safety certificates for production and application, and the cultivated new strains can reduce the cost of manual weeding by more than 30 yuan/mu and increase the yield by more than 5% compared with the control varieties.

　　In addition, China’s genetically modified rice, wheat and other products have formed a certain reserve. The research and development of insect-resistant rice is leading in the world, and it has obtained the safety certificate of production and application and the import license of the United States. The insect-resistant effect of this rice is over 95%, the pesticide consumption can be reduced by over 60%, and the yield is increased by over 10% compared with the control rice. The water use efficiency of the new drought-resistant and water-saving transgenic wheat strain is improved by more than 10%, which can greatly reduce irrigation water and effectively alleviate the problem of water shortage.

　　The Research Achievements of Patent Navigation in Biological Breeding Industry released by China National Intellectual Property Administration Intellectual Property Development Research Center shows that at present, the number of patent applications for biological breeding in China ranks first in the world, and the number of patent applications for molecular marker breeding has surpassed that of the United States, making it the country with the largest number of applications. However, on the whole, there is still a big gap between China’s biological breeding and developed countries such as the United States and Europe, and it is still possible to be "stuck".

　　Wan Jianmin, an academician of China Academy of Engineering and vice president of China Academy of Agricultural Sciences, said that there is an era gap between China’s biological breeding and foreign advanced level. Some foreign scientists have divided the breeding development into four eras, namely, the era of farmers’ selection, the era of phenotypic selection, the era of molecular breeding, and the era of big data intelligent design breeding. The world-class seed industry has moved towards the 4.0 era of design breeding, while the seed industry in China is still in the process of moving towards the era of molecular breeding.

　　He said that biological breeding is the core of seed industry innovation. Building a modern biological breeding innovation system, strengthening the deep excavation of germplasm resources, breaking through the key technologies of cutting-edge breeding, cultivating strategic new varieties, and realizing self-reliance and self-reliance of seed industry science and technology are the key to solving the "seed source" and winning the seed industry’s turnaround, and the fundamental guarantee for firmly grasping the initiative of food security.

　　Li Jiayang, an academician of China Academy of Sciences and a researcher at the Institute of Genetics and Development of China Academy of Sciences, believes that the future development direction of agriculture is high and stable yield, high-quality nutrition, high efficiency and safety, and agricultural industrialization. China’s agricultural modernization has reached a new stage of accelerating the transformation of development mode, and we must rely more on science and technology to achieve innovation drive, and continuously provide a strong driving force for agricultural development transformation and upgrading, quality improvement and efficiency improvement. Biological breeding is a very important aspect to ensure national food security in the future. In the future, we will further apply biological breeding technology to cultivate more high-yield, high-quality, stress-resistant and efficient seeds through propagating Silicon Valley in the south, so as to ensure national food security and make everyone eat well, eat well and eat healthily.

This is the "Guide to the Core Literature of Social Media Research"

001 articles

Starting today, we hope to do an interesting and important thing: to sort out the core literature of social media research and try to draw an academic map for this field.

Today, the 001st paper of this project is pushed, and it is also the most cited paper in social media research: Social Website: Definition, History and Academic Map.

Boyd, D.M., & Ellison, N.B. (2007). Social Network Sites: Definition, History, and Scholarship. Journal of Computer ‐ Mediated Communication, 13 (1), 210-230. (Cited: 18601)

The question we want to answer is:

★ In this paper, how do Boyd and Ellision define social networking sites?

★ What does this definition inspire the research of social networking sites?

★ What amendments have been made to this definition in the follow-up study?

Of course, in addition to reading, if you are interested in this plan and want to "blend in" together, please read the project plan at the end of the push and contact us.

In the history of social networking sites, 2007 is worth remembering. At the end of this year, Read/WriteWeb, a well-known Internet technology review blog, decided to award the IT company of the year award to Facebook, not Google. The reason is that Facebook broke the closed system of traditional social networking sites and allowed users to obtain plug-ins from third-party companies in the site. In other words, since then, Facebook has raised its "connection" potential to a new level and become an open co-writing space.

In 2007, beyond the commercial horizon, social networking sites, as academic research objects, also ushered in its landmark works, and the key word was still "connection". If we look back in 2007, a lot of academic research on social networking sites has been accumulated in the field of humanities and social sciences, but the dialogue between them is still incomplete and needs to be integrated urgently. Therefore, the Journal of Computer Aided Communication (JCMC) published a special issue on social networking sites in 2007, and invited two scholars, danah boyd and Nicole Ellison, to write an opening article. In this opening article, two scholars discussed the definition, history and academic map of social networking sites. Among them, their definition of social networking sites has been widely cited by subsequent studies and has become a classic work in the field of social networking sites.

Here we need to briefly explain from three levels why "definition" is important for social networking sites. First, the definition represents the boundary of research. Tampering with raymond carver’s words means what we are talking about when we are talking about social networking sites. Second, the definition focuses on the research field of vision. In our definition, we distinguish social networking sites from other types of websites, and the difference is likely to be the focus of follow-up research. Third, the evolution of definition also reflects the changes of technology. Social networking sites are essentially evolving with technological updates. In the following, we will focus on the definition of social networking sites in this paper and the revision of this definition in subsequent research.

In boyd and Ellison’s review, as of 2007, social networking sites have experienced three stages of development. Sixdegree.com, established in 1997, is regarded as the starting point of social networking site. However, perhaps because it was too ahead of the times, the site announced that it would stop operating in 2001. 2003 witnessed the second stage of the development of social networking sites. Many social networking sites have mushroomed and gradually become mainstream. One of the representative websites is MySpace, which we are familiar with. Then, in the third stage, the appearance of Facebook expanded the influence of social networking sites to a global scale. So, can we sort out a common clue for these different social networking sites? What are the similarities between them, which can be summarized under the same noun?

In this paper, the two authors define social networking sites as follows:

"We define social networking sites as an Internet-based service. It allows individuals (1) to establish a public or semi-public personal homepage in a closed system; (2) establish a connection with other users and present a list of contacts on the personal homepage; And (3) viewing and shuttling through the list of connections established by oneself and others in the system. The nature and naming of these links may vary from website to website. "

Next, we will briefly interpret these three characteristics:

1. Home page

The first keyword in the definition of social networking sites is the home page. Personal homepage is the pillar of social media and the basic unit and node of social networking sites, which is one of the most important differences between social networking sites, instant messaging tools and BBS. According to boyd and Ellison, the magic of personal homepage is that it allows users to "type themselves into being". For example, users need to fill in a series of questions on their personal homepage, such as head portrait, age, residence, interests, and a series of "about me" information. This process is self-sketching. Therefore, it is not difficult to understand why the research on self-construction and impression management in social networking sites has been launched since the 1990s and has become one of the core concepts of the research.

Step 2 connect

The second keyword in the definition of social networking sites is connection. The author thinks that the uniqueness of social networking sites is not that they allow individuals to meet strangers, but that they allow users to show their social networks. This is another important difference between social networking sites and instant messaging tools. What excites researchers is that this relationship has different names in different social media-Weibo calls it "fans", Twitter calls it "followers" and Facebook calls it "friends". So, what is the relationship between people in social networking sites? More interestingly, when social networking sites use the title "friend", how will the meaning of the word "friend" change quietly?

Step 3 shuttle

The third keyword in the definition of social networking sites is traverse. This word has at least two dimensions. First, people can shuttle through their friends lists and check their friends’ messages at any time, so they can establish their own relationship network; Secondly, people can often check who their friends have. Recall that when Sixdegree.com used the metaphor of "six dimensions" in naming, he actually expressed the value of the second layer of shuttle. Similarly, one of the visions of Tinder, a dating software, is to firmly believe that people with common friends are more likely to become friends. If we continue along this line of thought, we will surely meet Caroline Haythornthwaite’s classic research on "latent ties" in 2005. Of course, from another perspective, when you are shuttling with other people’s homepages, you are also being shuttled by others. This also explains why privacy and visibility will become an important clue in the research of social networking sites.

Since its publication, the paper I introduced to you has been cited by tens of thousands of follow-up studies, most of which focus on its definition of social networking sites. However, if we stand in today’s coordinates and look back at this definition more than ten years ago, we may feel some old traces of the times. With the evolution of technology, have these three keywords changed? After all, definition can only be responsible for defining "being", but not for predicting "becoming".

In 2013, boyd and Ellison joined forces again to update the three characteristics of this definition, which are briefly described as follows for your reference:

(1) The importance of personal homepage has been greatly reduced, and social networking sites have changed from homepage-oriented socialization to behavior-oriented socialization. Even if the homepage still exists, it is no longer a static self-description, but a dynamic combination of different types of status updates.

(2) Friend list no longer only describes the circle of friends of users, but more importantly, it shows a social graph of users through algorithms.

(3) Social networking sites provide more possibilities for shuttle. Users used to only use social networking sites to establish and maintain their own relationship circle, so shuttle is closed in nature. With the continuous introduction of new functions, this closeness has been constantly broken. For example, hashtags allow people to jump out of their circle of friends and meet strangers at a more public level.

Accordingly, boyd and Ellison also gave a new definition of social networking site:

Social networking site is a networked communication platform, in which participants (1) have a unique and identifiable personal homepage, which includes the content provided by users themselves, the content provided by other users, and the data content at the system level (2) can publicly display their social relationships and be browsed and shuttled by others (3) can consume, produce and/or interact with the content stream provided by contacts in the site.

This change in technology and culture can also be reflected in the purport of researchers, such as algorithms and privacy, tag community and other research topics have gradually emerged and highlighted. Of course, even if the definitions provided by boyd and Ellison are updated, it has been seven years since this article was written. What changes have taken place in the characteristics of social networking sites? What surprises can these changes provide for our research and thinking?

From this point of view, American scholar Jeff Pooley is right, and communication research is destined to be a humble undertaking, because the continuous updating and iteration of technology will make us push a stone up the mountain like Sisyphus in Greek mythology, and then see it roll back again and again until forever.

Note: It should be noted that the two authors used "Social Network Site" instead of Social Media. If we make a diachronic analysis of the researcher’s choice of "wording", we will find the characteristics of the times. Between 2003 and 2008, the word "social networking site" was used twice as much as "social media" in research papers. However, from 2009 to 2014, this relationship was reversed, and social media has largely replaced the term "social networking site". Social media is the result of the continuous expansion of technology developers. Compared with social networking sites, it has a wider extension, or social networking sites have now condescended to become a subset of social media. See McCay-Peet & Quan-Haase, 2017.

Wang Tai, deputy director of the Highway Bureau of the Ministry of Transport, revealed at the promotion meeting of the national electronic toll collection (ETC) networking work held on the 9 th that before the end of this year, 14 provinces and cities such as Beijing will realize system networking operation; By the end of 2015, all provinces, autonomous regions and municipalities in China will basically realize the system networking operation.

"One to five", the economic and environmental benefits of electronic non-stop toll lanes are outstanding.

ETC system, also known as electronic toll collection system, is the most advanced road and bridge toll collection method in the world, and it is an effective way to solve the congestion of highway toll stations and improve traffic efficiency. The capacity of one electronic toll lane is equivalent to that of five manual toll lanes, and the average time for vehicles to pass through the toll booth has been reduced from 14 seconds to 3 seconds, which has shortened the time by nearly 80%. Through this technology, it can also save fuel consumption and reduce pollutant emissions.

In addition, through the implementation of regional networking, it also provides a guarantee for the rapid passage of expressways for regional integration. Since the electronic toll collection system was opened in 2010, the average annual growth rate of the transaction volume of the inter-provincial electronic toll collection system in Beijing, Tianjin and Hebei has remained at around 60%, and the average annual growth rate in the Yangtze River Delta region is close to 90%.

After the exploration in recent years, the scale of the construction, popularization and application of electronic toll collection system in China has increased rapidly. Up to now, more than 7,100 dedicated lanes have been built nationwide, with more than 11 million development users.

Next year, the number of users will reach 20 million, and the main toll station will achieve full coverage.

However, the system promotion also faces many difficulties. Including the need to install electronic tags and purchase stored-value cards before using special lanes, the need to recharge at special points or banks, the slow progress of inter-provincial settlement, the implementation of superimposed charges for some routes and the imbalance of input-output ratio, which led to the lack of enthusiasm of investors.

In this regard, Feng Zhenglin, Vice Minister of the Ministry of Transport, introduced that the Ministry of Transport requested to build a national online clearing and settlement platform and formulate networking operation rules to jointly ensure that the national online clearing and settlement is fair, transparent, safe and efficient.

According to the plan, the nationwide networking work will be divided into two steps: before the end of 2014, 14 provinces and cities including Beijing, Tianjin, Hebei and Shanxi will be networked. By the end of 2015, a nationwide networked operation management mechanism will be established; The utilization rate of passenger cars is not less than 25%, and the utilization rate of non-cash payment reaches 20%; The system coverage rate of the main toll station reaches 100%; Customer service outlets cover county (district) level administrative regions; The number of users in the national system has reached 20 million; Realize the nationwide networking operation of military vehicles and armed police vehicles.

In addition, by the end of 2015, China will initially establish a national toll road networking data service system. By then, road network management departments at all levels will be able to deeply explore the potential value of vehicle operation information, strengthen statistical analysis of data, and provide decision support for road network operation management and government industry supervision.

　　Beijing, May 9 (Reporter Zhang Ni) Recently, the nine-valent cervical cancer vaccine (HPV vaccine) was approved for listing in China, bringing good news to many women. HPV vaccine is the first vaccine in the world to include cancer as an indication. However, for many domestic people, this vaccine is still new, and the popularity of related knowledge is still limited.

　　How to vaccinate? How to choose the vaccine type that suits you? What preparations need to be made before vaccination? A few days ago, the reporter from Zhongxin. com interviewed Zhao Yun, deputy chief physician of gynecology department of Peking University People’s Hospital, on a series of issues of public concern.

　　— — What is the relationship between HPV virus and cervical cancer?

　　HPV is the abbreviation of the English name of "human papillomavirus". There are many members in the HPV family, and a few of them are closely related to malignant tumors, so they are called high-risk HPV. From the statistics of large population samples, 99% of cervical cancer is caused by infection with this kind of virus.

　　The main route of transmission of HPV virus is through sexual contact, and mucosal contact can also be transmitted.

　　When there is no sexual exposure, the probability of this virus infection is almost zero, but the probability of HPV infection in women who have sex is very high. About 70% to 80% of women may have been infected with this virus, especially when they are sexually active (usually before the age of 30), which is the peak of infection.

　　However, many infections are transient infections. With the increase of age, these viruses will be cleared away, and only a small number (10-15%) are in a state of persistent infection, which is the high-risk group of cervical precancerous lesions and cervical cancer.

　　— — What is the difference between bivalent, tetravalent and nonavalent vaccines?

　　At present, there are three kinds of HPV vaccines listed in the world: bivalent, tetravalent and nonavalent.

　　A bivalent vaccine can prevent infections caused by HPV16 and HPV18 viruses. International research data show that more than 70% of cervical cancer is caused by these two viruses.

　　The tetravalent vaccine can prevent the infection of HPV6, 11, 16 and 18 viruses. Although HPV6 and HPV11 are not high-risk HPV viruses of cervical cancer, they can cause condyloma of lower genital tract.

　　Nine-valent vaccine is aimed at nine subtypes of HPV6, 11, 16, 18, 31, 33, 45, 52 and 58. Studies show that nine-valent vaccine can prevent 90% of cervical cancer.

　　It should be pointed out that HPV vaccine can not prevent cervical cancer 100%, even after vaccination, cervical cancer screening should be carried out regularly.

　　— — What is the difference between the three vaccination ages?

　　In terms of vaccination age, the approved vaccination age in China is: bivalent vaccine is suitable for women aged 9-25, tetravalent vaccine is suitable for women aged 20-45, and ninevalent vaccine is suitable for women aged 16-26.

　　The division of age groups is determined based on the results of clinical experiments of different age groups in China. HPV vaccine is a preventive vaccine. At present, no results show that it has the effect of preventing diseases for people who have been infected with HPV virus contained in the vaccine. Therefore, population vaccination before sexual exposure has the best health economic effect.

　　In the position paper updated by WHO in May 2017, it is suggested that women aged 9-14 who have not had sex should be the main target population, and women over the age of 15 should be the secondary target population.

　　— — Is the applicable age of nine-valent vaccine in Hong Kong 9-45 years old?

　　The instructions for the nine-valent vaccine in Hong Kong are applicable to 9-45 years old. However, there is no clinical data on the effectiveness of using HPV nine-valent vaccine in people over 26 years old.

　　Hong Kong’s approval of the application for the elderly is mainly based on the effectiveness of the tetravalent vaccine for the elderly population. The nine-valent vaccine and the tetravalent vaccine are immune-bridged, so the application range is 9-45 years old.

　　— — Is it still useful to vaccinate married and fertile women?

　　Some married and fertile women have not been infected by the virus, or have not been infected by the HPV subtype contained in the vaccine. At this time, vaccination is also effective.

　　— — How many times does the vaccine need to be vaccinated?

　　The bivalent, tetravalent and nonavalent vaccines all need to be injected in three times and completed within six months.

　　Among them, bivalent vaccine is recommended to be inoculated in October, January and June, with a total of 3 doses. The second dose can be inoculated 1-2.5 months after the first dose, and the third dose can be completed 5-12 months after the first dose.

　　Four-valent and nine-valent vaccines are recommended to be vaccinated in October, February and June, with a total of three doses. The interval between the first dose and the second dose should be at least one month, and the interval between the second dose and the third dose should be at least three months. All three doses should be completed within one year.

　　— — Is it still necessary to vaccinate with nine valence after vaccination with four valence?

　　At present, there is not enough evidence to prove that it will be more beneficial to vaccinate another series after completing one series of vaccines.

　　From the clinician’s point of view, women who have been vaccinated with one of bivalent, tetravalent and nonavalent vaccines and completed all injections can prevent more than 70% of cervical cancer. Another HPV vaccine injection is not recommended.

　　The instructions for the nine-valent vaccine mentioned that after the third dose of tetravalent HPV vaccine was inoculated, the nine-valent vaccine was injected at least 12 months apart.

　　— — How long is the vaccine valid?

　　Bivalent and tetravalent vaccines have been on the market for more than ten years. At present, the research data show that the antibody level of the vaccinated population is still at a high level, and there is no evidence that it is necessary to strengthen vaccination.

　　The nine-valent vaccine was launched in 2014. Studies on people aged 9-15 and 16-26 showed that serum antibodies remained positive in the fifth year after vaccination. At present, there is no evidence of the need for intensive vaccination.

　　— — What tests should I do before vaccination?

　　No special examination is needed before vaccination. However, in my personal opinion, people who have been sexually exposed and have never been screened for cervical cancer before should be screened. The purpose of screening is to know whether they have cervical lesions.

　　— — Which groups are not suitable for vaccination?

　　People who are allergic to the active ingredients used in the vaccine or any dressing adjuvant should be prohibited from using it. People who have had hypersensitivity after injecting HPV vaccine should not be vaccinated again.

　　In addition, women who are pregnant and pregnant are not recommended to be vaccinated now. Although a large number of practices that have been put on the market have proved that there is no data showing that the vaccine will affect the growth and development of embryos, pregnancy preparation and pregnancy are special periods, so it is not recommended for such people to be vaccinated immediately.

　　— — What are the side effects of the vaccine?

　　At present, the safety of the vaccine is still very good. Vaccination of this kind of vaccine is the same as other vaccines. The common systemic adverse reactions are mainly headache, fever, nausea and dizziness, and the local adverse reactions are mainly pain, swelling, erythema and itching.

　　— — Can men be vaccinated?

　　At present, all vaccines approved in China are used by women to prevent cervical cancer.

　　In foreign countries, tetravalent vaccines approved by some countries can be used for male vaccination. Male vaccination can also prevent precancerous lesions of some reproductive organs, condyloma and so on.

　　In addition, male vaccination is beneficial to the emergence of group immune effect, which reduces the overall infection rate of HPV virus in the population.

　　— — What are the precautions for preventing cervical cancer?

　　To prevent cervical cancer, in addition to vaccination, regular screening should be conducted, especially for women who have had sexual exposure.

　　For healthy people under the age of 30, it is suggested that only cell screening should be carried out. If the screening result is negative, it can be checked again after 3 years. For healthy people over 30 years old, it is recommended to carry out cell screening and HPV virus examination. If the results are double negative, they can be examined again after 5 years.

　　Early sexual exposure, many sexual partners, active sexual behavior and unclean sexual behavior are all high risk factors for cervical cancer, so condoms are recommended for safe sex. In addition, developing a healthy lifestyle is also beneficial to the prevention of diseases.

　　BEIJING, July 15 (Xinhua) On July 14, the 8th Global Bulk Grain and Oil Industry Summit kicked off in Chengdu, Sichuan. Major large-scale bulk grain and oil producers, processors, traders, industry associations, scientific research institutions and machinery and equipment manufacturers from many countries and regions around the world attended the meeting. The global bulk grain and oil industry summit was hosted by the China Chamber of Commerce for Import and Export of Food, Livestock and Animals. Domestic and foreign bulk grain and oil experts gave special speeches and various forms of discussions and exchanges on the supply and demand situation of the world grain and oil market, food hygiene and safety, product marketing and related new technology issues.

　　Bian Zhenhu, president of China Chamber of Commerce for Import and Export of Food, Livestock and Animals, said that China’s continuous opening-up has contributed a lot of positive energy to the global economic recovery. He said, "Despite the downward pressure on economic development, the trade of bulk grain and oil products between China and the international community has risen and fallen, fast and slow, but it is undeniable that China is the most reliable driving force and kinetic energy for the demand for grain and oil products in large economies." Bian Zhenhu believes that China’s domestic consumer market has huge capacity, great potential and considerable prospects, which will be beneficial to the development of various forms of cooperation in the grain and oil field for a long time. He expressed full confidence in the large-scale grain and oil cooperation in the global field.

　　As one of the partners of this summit, the Sustainable Palm Oil Roundtable Initiative (RSPO) attaches great importance to the role and position of China’s sustainable palm oil import and export in promoting the transformation of the global palm oil market, and is committed to promoting RSPO-certified sustainable palm oil to become the industry norm in China. Darrel Webber, CEO of RSPO, said that RSPO currently has more than 2,900 members worldwide, and all members are committed to producing, purchasing and trading palm oil in a sustainable way. China is the second largest palm oil importer and the third largest palm oil consumer in the world. Darrel Webber revealed, "RSPO and China Chamber of Commerce for Import and Export of Food, Livestock and Animals are jointly working out a report, which can let you know the consumption situation of palm oil in China and provide you with necessary information and help." It is reported that "China Sustainable Palm Oil Supply Chain Forum-RSPO China Forum" was held in Chengdu on July 13th, which introduced the development of RSPO in China and its expectation for the future sustainable palm oil, and actively advocated the development of sustainable palm oil in China through multi-party cooperation.

Recently, a group of real car drawings of FAW-Volkswagen’s brand-new Magotan were exposed on the Internet, which is officially called the brand-new Magotan B9. It is reported that it will be officially unveiled at the Beijing Auto Show, which opened on April 25th.

From the appearance, the new Magotan B9 adopts a brand-new popular family design style. The front grille with narrow banners is connected with the headlights on both sides, which further widens the visual width of the front of the car. There is a penetrating chrome-plated decorative strip in the middle of the grille. The Volkswagen LOGO in the middle can be lit, and there is also a penetrating light belt on the side of the LOGO. In addition, the decorative strip and diversion groove at the lower part of the front of the car have to admit that the front face of the new Magotan B9 does have a sense of technology and sports. No small improvement.

For the car side, the new Magotan B9 has a body size of 4990 mm /1854 mm /1487 mm and a wheelbase of 2871 mm, which is still a very standard medium-sized car. The waistline from the front of the car to the rear of the car is matched with a brand-new two-color large-size wheel hub, which really ensures the sense of movement on its side. As for the rear of the car, the penetrating taillights are the biggest highlight, which enhances the layering and also ensures the fashion sense of the rear.

In terms of interior, the new Magotan B9 also adopts a typical Volkswagen brand design style, but it has improved its sense of technology. Its car is equipped with three screens, a full LCD instrument panel, a large-size central control screen and a co-pilot entertainment screen, which is also adopted for the first time on Magotan models. And in the aspect of multimedia system, it will also adopt the brand-new system of Volkswagen. In addition, there is another change: the new Magotan B9 is designed with a shield, which leaves more storage space in the center console.

In the power part, according to the previous application information, the new Magotan B9 will be equipped with a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. The maximum power of the 1.5-liter turbocharged engine is 118 kW, and the maximum power of the 2.0-liter turbocharged engine is 162 kW.
