Write in front

At present, in order to thoroughly implement the strategy of strengthening the army with talents in the new era, promote the comprehensive transformation and upgrading of military personnel’s ability and quality, structural layout, development and management, and forge high-quality and professional new-type military personnel with both ability and political integrity, we must persistently use the supreme leader’s Socialism with Chinese characteristics Thought in the new era, especially the supreme leader’s thought of strengthening the army, to cultivate people, to deepen reform and solve problems in reform, to crack contradictions in development with innovative development, and to promote the development of military education in a high-quality direction with effective measures.

Strengthen the strength of "unification" and give full play to the comprehensive educational function of the trinity new military talent training system

Constructing a new pattern of trinity talent training is a milestone for our military education to enter a new era and a high-quality development track. It needs to be optimized and improved in deepening practice, improving quality and increasing efficiency.

Understand the operating mechanism of the new military personnel training system. Focusing on the cultivation of high-quality and professional talents, military academy education as the main channel focuses on solid foundation, military training practice focuses on transformation and application in large classrooms, and military vocational education is a big platform focusing on filling gaps and expanding. It is necessary to focus on giving full play to their respective strengths, establish and improve a mechanism of integration, complementarity and linkage based on unified personnel training objectives, quality standards and resource management, and jointly support military personnel training to achieve high-level operational goals.

Give priority to the development of military academy education. Strengthening the army first strengthens the school, and college education plays a fundamental, leading and overall role in army building. It is necessary to carry forward our army’s fine tradition of running schools and educating people, aim at the goal of building first-class military academies and training first-class military talents, strengthen the unique functions of colleges and universities, such as cultivating and reserving talents, innovating theories and developing technologies, leading the transformation of combat training and testing combat capability, and truly implement the priority development strategy of colleges and universities with rigid measures, so as to make colleges and universities a well-deserved "locomotive" for the construction of our army’s combat effectiveness.

Strengthen military training, practice and cultivate talents. Military training practice is an important link in the talent training chain, a key step to accelerate the development of officers and men, and an ideal examination room to test the actual ability of war talents in peacetime. It is necessary to guide officers and men to base themselves on their post responsibilities, flexibly transform and apply the thinking concept, theoretical knowledge and basic ability learned in colleges and universities in the practice of training and preparing for war, improve their ability and quality in the practical task tempering, and lay a solid ladder for the career development of officers and men.

Comprehensively promote military vocational education. Military vocational education has irreplaceable strategic value for officers and men to update their knowledge, keep up with the times, be competent for their posts and enhance their abilities, and is an important support for building a learning-oriented military camp in the new era. It is necessary to focus on fighting, focusing on posts, focusing on urgent needs and focusing on the frontier to carry out post re-education and retraining for officers and men, strengthen motivation and policy drive, standardize post self-learning activities such as improving performance ability, preparatory training for college education, vocational qualification certification and skill appraisal training, upgrading on-the-job academic qualifications, and improving scientific and technological literacy, and accelerate the construction of a pattern of officers and men learning from time to time, learning everywhere, learning for everyone, and lifelong learning.

Highlight the standard of "specialization" and improve the ability and level of military education to prepare for war.

The basis of the actual combat capability of the army is specialization, and the core of the military professionalism level is specialization. With the increasing complexity of the technical composition and knowledge-intensive degree of the army, it poses a greater challenge to the professionalism of all kinds of military talents, which requires that military education must put specialization construction in a more important position.

Firmly establish the concept of running a school professionally. Clearly establish the school-running idea of creating characteristics by specialization, emphasizing quality by specialization and seeking development by specialization, insist on taking professional ability as the core factor to evaluate the quality of personnel training, take professional characteristics as the key index to measure the level of education and training institutions, adopt classified construction, classified management, make overall arrangements and differentiate the resources of colleges and training institutions, and strive to make each educational entity unique in its respective professional fields.

Build a strong professional discipline system. Focus on the needs of preparing for war, twist the main training task of training units, comprehensively use the methods of changing birds in cages and substantive integration, inherit the inherent genes of traditional dominant disciplines, vigorously strengthen the supporting disciplines for preparing for war, vigorously cultivate new fields and new quality disciplines, deepen the transformation of traditional disciplines "military+"and "intelligence+",promote the intensive allocation and utilization of specialized educational resources, and continuously improve the advanced and sophisticated level of disciplines.

Forging professional teachers. In strict accordance with the professional standards, teachers’ qualifications for admission and the selection of college presidents are set, so as to attract the best talents from the military and local areas to run schools, and strive to build a teaching staff with high professional level and always full of vitality.

Strengthen professional evaluation and supervision. Give full play to the "baton" function of education evaluation and the "corrector" function of education supervision, evaluate the quality of teaching, construction and education with the advantage of specialization as the core index, take the implementation of professional construction planning plan and the implementation of laws and regulations as the focus of education supervision, and strongly guide military education to accelerate the connotative development based on specialization.

Focus on the traction of "war" and promote the transformation and upgrading of military education with the innovation of talent training mode

Military education is born of war and built for war. We must always focus on actual combat, focus on winning and cultivating talents, and integrate military theory innovation, high-tech breakthrough, future war design and talent cultivation, so that the cultivated talents can always stay ahead of the war and opponents.

Improve the mechanism for selecting students. In the future, intelligent warfare has high requirements for military talents’ cognitive ability, learning ability and innovation ability. The selection of cadets of growth officers should highlight the investigation and screening of intelligence level and military professional potential, and attract outstanding talents in a larger space and scope. In accordance with the selection criteria for senior and middle-level officers, trainees in post education should choose the best among them and enter the school to receive systematic training, and at the same time complete the task of continuing education for all other personnel through military vocational education.

Optimize the talent training system. Adapt to the new requirements of the changes of war, science and technology and opponents on the ability and quality of officers and men, and dynamically optimize the generation mechanism of talent training needs. According to the basic standards of national higher education and the objectives and specifications of military education and training at all levels, and following the law and characteristics of the growth of different professional talents in the arms and services, the training methods of various talents are designed differently.

Innovate the teaching mode in an all-round way. Strengthen actual combat teaching by emphasizing competence, and achieve the docking of course content and post standards, teaching process and combat process, and training organization and battlefield requirements in post education; Strengthen individualized teaching and encourage students to fully demonstrate their originality under the constraints of common norms; Using information technology to develop new forms of teaching, to meet the characteristics of different types of training, and to create the best learning plan and teaching process suitable for everyone.

Create a smart education environment. Adhering to the student-centered concept, we will carry out the pilot project of digital construction of military education, create a simulated confrontation teaching environment with real experience, intelligent driving and iterative upgrading by using virtual reality technology, and build a military wisdom education platform to support the transformation of military education.

Promote the depth of "connection" and take the road of joint education and open education.

Military education should be oriented to the world’s military frontier, to the important needs of national security, and to the modernization of national defense and the army. It is impossible to do it behind closed doors, and we must persist in opening up and educating people.

Get through the talent training link. It is necessary to strengthen the seamless connection of education and training at all levels, design the talent training framework in an integrated way, determine the training objectives and specifications by classification and stratification, focus on the orientation of different colleges and universities, intensively allocate educational resources, and explore the construction of a talent training pattern that integrates college education with on-the-job education, academic education with on-the-job education, junior high school and senior high school command education, meets the practical needs and pre-sets training smoothly.

Adhere to the direction of the United Education Association. Strengthen the combination of theory and practice between colleges and universities and the army, focus on fundamentally solving the problem of "acclimatization", hand over the "last mile" of training officers to the army, and explore the mechanism of graduation only after passing the post practice; In order to make up for the congenital deficiency of educational practice ability in colleges and universities, we try to entrust some practical courses such as command, management and group training to army commanders, entrust comprehensive training tasks and large-scale weapons and equipment teaching to designated troops, and promote the efficient use of practical teaching and training resources through accurate planning.

Shaping the pattern of integrated education. Strengthen the introduction and sharing of local high-quality educational resources, build a collaborative innovation platform through military and civilian cooperation, and promote the joint training of high-end talents on a larger scale and at a higher level; We should extensively tap and utilize the high-value resources of talents, information and security in local colleges and universities to improve the overall efficiency of military education.

The average monthly income of migrant workers last year was 3072 yuan, and the starting salary exceeded that of college students.

  On April 28th, China Construction Third Bureau and Third Company organized a commendation activity for outstanding migrant workers as "builders and descendants of Luban" in Wuhan. People’s Daily reporter Cheng Yuanzhou photo

  "The starting salary of migrant workers exceeds that of college students", "The wages of migrant workers are rising too fast, and enterprises are under great pressure" … … This statement has appeared frequently in the past two years. What is the salary status of migrant workers? How fast is it rising? Ministry of Human Resources and Social Security Labor and Wage Research Institute has provided an exclusive report on migrant workers’ salary for this newspaper.

  Compared with urban workers, it is still low.

  How fast did the wages of migrant workers increase during the Twelfth Five-Year Plan period? The project report shows that in 2015, the last year of the Twelfth Five-Year Plan, the average monthly income of migrant workers was 3,072 yuan, while in 2010, the last year of the Eleventh Five-Year Plan, the average monthly income of migrant workers was 1,690 yuan, with an average annual increase of 12.7%.

  Among them, the average monthly income of migrant workers in 2011 was 2,049 yuan, a year-on-year increase of 21.2%. Such a high growth rate attracted special attention. In the following years, the wage increase of migrant workers tended to be stable. In 2012, the average monthly income of migrant workers was 2,290 yuan, up 11.8% year-on-year; In 2013, the average monthly income of migrant workers was 2,609 yuan, an increase of 13.9%; In 2014, the average monthly income of migrant workers was 2,864 yuan, a year-on-year increase of 9.8%; In 2015, it increased by 7.2% year on year.

  Generally speaking, in the past few years, the wages of migrant workers have achieved rapid growth. However, the report also pointed out that due to the low base, the salary level of migrant workers is still low compared with that of urban workers, which basically remains at around 60%. Looking at the absolute amount, the gap between the wages of migrant workers and the average wages of urban workers has not narrowed. In 2011, the annual wage gap between them was 17,864 yuan, and in 2014 it reached 21,971 yuan.

  Regionally, in the early period of the Twelfth Five-Year Plan, the income growth rate of migrant workers in the central and western regions was higher than that in the eastern region, and the income gap between the eastern and central and western regions gradually narrowed. From the employment location of migrant workers, the income level and increase of migrant workers in big cities are significantly higher than those in medium and small cities. This can also explain why migrant workers flock to big cities.

  To some extent, the rapid rise is "compensatory growth"

  The average annual growth rate of migrant workers’ income is 12.7%, far exceeding the GDP growth during the Twelfth Five-Year Plan period. How to improve the salary of migrant workers quickly? According to the analysis of the report, there are three main factors.

  First, China’s sustained economic development is the main factor of migrant workers’ salary growth. During the "Twelfth Five-Year Plan" period, although China’s economy has been affected by the international environment and its speed has slowed down, it is still the fastest growing country among the major economies in the world. In the same period, employment remained stable. For five consecutive years, the number of new jobs in cities and towns remained above 12 million, and the registered unemployment rate in cities and towns remained at 4.1%. This provides support for the continuous increase in the wages of migrant workers.

  Second, the improvement of the minimum wage standard creates favorable conditions for the salary growth of migrant workers. During the Twelfth Five-Year Plan period, the average annual increase of the minimum wage reached 13.1%. By 2015, the highest standard in Shenzhen has reached 2030 yuan, and the highest level of minimum wage in all provinces, autonomous regions and municipalities has exceeded 1100 yuan. Most migrant workers are at the low end of the labor market, and their salary level is greatly affected by the minimum wage. During the Twelfth Five-Year Plan period, the adjustment of the minimum wage has a wide range and a fast frequency, which has played an important role in the salary growth of migrant workers.

  Third, the education level and training of migrant workers themselves have been continuously improved, which has promoted the improvement of migrant workers’ salary level to some extent. In recent years, China has implemented a series of vocational skills upgrading plans for migrant workers. By the end of the Twelfth Five-Year Plan, the proportion of migrant workers who have received training has continued to increase, accounting for more than 35%.

  In addition, the rapid increase in the salary level of migrant workers since the "Twelfth Five-Year Plan" is also a reasonable return to the abnormal phenomenon of long-term low salary of migrant workers. The wages of migrant workers have been hovering at a low level before 2008. In the Pearl River Delta and other places, the average monthly wages of migrant workers have only increased in 68 yuan in the past 10 years. According to the report, the rapid increase in the wages of migrant workers in the past few years is a "compensatory increase" to some extent, and it is also an objective reflection of the reality that the relationship between supply and demand in China’s labor market is undergoing profound changes and the cost of living in cities is rising rapidly.

  Labor supply and demand determine that wages still have room to rise.

  At present, there are still many unsatisfactory places in the salary of migrant workers.

  The phenomenon of wage arrears for migrant workers has not been fundamentally solved. The construction industry is still a frequent place where wages of migrant workers are owed. What needs to be paid attention to is that the amount of wage arrears has increased a lot in recent years. In addition, migrant workers work long hours and work overtime seriously. During the "Twelfth Five-Year Plan" period, the average annual employment time of migrant workers is about 10 months, the average monthly employment time is more than 25 days, and the average daily employment time is about 8.8 hours. The number of migrant workers who work more than 44 hours per week stipulated in the Labor Law has been as high as 85%, and many migrant workers are forced to work overtime "voluntarily".

  Some people believe that with the slowdown of economic growth, the time when the wages of workers, including migrant workers, are growing at a high speed is gone forever. What will happen to the wage growth of migrant workers in the future? According to the report of the Institute of Wages of the Ministry of Human Resources and Social Security, the wages of migrant workers in China still have a large room for improvement.

  On the one hand, China’s economy will continue to grow at a certain speed, and the labor market will continue to release a considerable number of jobs. However, after years of large-scale and continuous transfer, China’s agricultural labor force has shown a trend of increasing the total amount and decreasing the growth rate. The rural labor force has changed from unlimited supply to limited supply, and it has moved towards equal supply and demand. This change in supply and demand will directly affect the wage income of migrant workers. On the other hand, China’s labor wage cost is still significantly lower than that of developed countries and some developing countries. Although it is higher than that of some neighboring countries in recent years, the labor productivity has increased rapidly in the same period and still has considerable advantages. Considering that the average monthly wage of migrant workers is only about 60% of the average monthly wage of urban workers, the project report predicts that the wage level of migrant workers will continue to increase in a certain proportion in the next few years, which is expected to reach about 10%.

Nine, football dribbling

(1) Site setting and equipment specifications

The field is set on the flat ground in the middle of the track and field or on an independent football field. The surface is natural or artificial lawn (not smooth hard ground), and the fields are independent from each other to avoid mutual interference during the examination. The setting requirements are as follows:

It is 30 meters long and 10 meters wide, and obvious marking lines are set around the site. Sign poles are set up 5 meters before the starting line. The distance between the sign poles and the side lines on both sides is 5 meters, with a total of 5 poles, and the distance between the poles is 5 meters. One meter in the middle of the starting line is the departure area for candidates. The setting method is as shown in the figure:

The height of the marker post is not less than 1.2m, the size of the test ball is No.5 football (its weight is 396~453g, and its circumference is 680~710mm), and the air pressure in the ball meets the requirements of football competition rules.

(2) Test methods

The guide will take the candidates to the examination venue in groups for identity confirmation (photo of the handheld education examination card is compared with my appearance) and check-in. After hearing the number, candidates will transport the ball to the starting area behind the starting line and make preparations for departure. After giving the order, the examinee dribbles forward and winds the pole in turn; After the ball passes the last post, the examinee touches the ball at least once and dribbles through the finish line; When both the man and the ball have crossed the finish line, the timing stops. Each person tested twice and recorded good results.

Record the test results in seconds, accurate to 1 decimal place (0. 1 second), and enter L when the second decimal place is not "0".

When the exam is fouled, the score will be invalid; Those who have fouled twice without results can only have one more chance; Those who still violate the rules will get 0 points for this score.

After hearing the number, the examinee enters the test area and throws the ball in place. After the first ball cushion is successful, the timer starts, and the individual continuously cushions the ball with both hands, requiring the correct hand shape, accurate hitting position and the specified height.

Each test should last no more than 1 minute. Each person takes the test twice, and records the better one.

If the cushion ball does not exceed the time limit, the ball lands or commits a foul, and the test is over; In case of overtime, the test will automatically end after the specified time. The height of the boys’ cushion ball (from the ground to the bottom of the ball) is not less than 2.24 meters, and the girls are not less than 2.00 meters. Only when the method is correct and the height meets the requirements can the cushion ball be counted. Count the number of cushion balls.

When the candidates take the exam, the ball touches the marker, and the consequences are borne by the candidates; In case of foul behavior, when the test is over, the number of cushion balls shall be based on the number recorded by instruments and equipment at the time of foul.

Old Houses and Old Houses in Chinese: Japanese Renovation Plan

Recently, MUJI held an event called "Joy City" on the 3rd floor of Shanghai.Compact Life in China"The exhibition. The objects on display include modular cabinets of Muji, and daily groceries such as acrylic storage boxes, and the three "homes" that attract the most attention — — They are all decorated and arranged by muji products from the inside out.

These "homes" are actually the result of the transformation of three ordinary homes in Shanghai by the MUJI team. Each home has experienced a change from "dirty, chaotic and poor" to neat, simple and comfortable. These changes were recorded as short videos by time-lapse photography and played circularly at the exhibition site. In addition, the finished products were restored to the scene at 1: 1.

Previously, MUJI had done similar renovations and exhibitions in Japan, Taiwan, China and Hongkong, with the aim of promoting its modular furniture through the concept of "Compact Life" — — But aside from this, the exhibition still gives a lot of inspiration about home design, especially the renovation of old houses.

"This clean and bright Japanese style, compared with the previous renovation of the husband’s room, really makes people have the desire to modify their own homes." Just finished visiting.Compact Life in ChinaThe audience of the exhibition, Chi Cheng, told the interface reporter.

When it comes to the renovation of old houses, many people may think of a variety show called Dream Renovator. More than a year ago, this program caused a heated discussion by virtue of the strong contrast before and after the house renovation and various dramatic conflicts and turning points during the renovation process. Among them, the episode of Shuhei Aoyama, a Japanese architect, transforming Beijing quadrangles was the most popular.

The reason is: firstly, the program group crowned this quadrangle transformed by Shuhei Aoyama with the title of "the smallest school district in history", which increased the audience’s expectation for the transformation, and also made the contrast between the transformed "Japanese-style residence" and the quadrangle before the transformation stronger; On the other hand, Shuhei Aoyama’s Japanese identity also makes the whole case more concerned.

"I like his style very much. I wish he were not Japanese." The netizen "dreams point to the south" said in a reply to the related post of "Dream Renovator" in Baidu Post Bar. This represents a voice: Japanese people working in China, especially those projects such as rebuilding old houses in China, will be more or less affected by some negative feelings from China people towards Japan.

But more often, Japanese designers are very popular in the market of renovation and renovation of old buildings in China — — A little search on the Internet will reveal that it is no exaggeration to describe the condition of Japanese designers’ renovation of old houses in China by "getting together".

In addition to Shuhei Aoyama and the MUJI team, world-renowned architects Kengo Kuma and Fujimoto Shosuke were invited to renovate the old quadrangle in Beijing. One of them made a Zen teahouse, and the other rebuilt the Beijing Humanities and Art Center. You may have heard of a Japanese architectural firm called odd, which renovated six or seven hutong houses in one breath in Beijing. In another program of Dream Renovater, Japanese designer Ben Shi’s attempt to renovate a husband’s house in Shanghai is estimated to have impressed many people.

These cases have one thing in common, that is, the area of the space to be renovated is not large, and it can even be said that it is cramped, crowded and messy. I don’t need to go into details about those quadrangles and hutongs. Most of the time, a room of more than ten square meters or even smaller has to accommodate at least five people and their sundries. Similarly, MUJI has also selected old houses built in the 1990s in Shanghai, with an area of about 40 to 50 square meters.

"Houses with renovation needs generally have the problem of small area, which is the same in Shanghai and Hong Kong, including Tokyo." Gu Benzhan, director of the planning and design office of MUJI’s life and groceries department, told the interface news, "Metropolis is a place where people gather. After more people gather, the natural living space and the area that can be effectively used will become smaller and smaller."

Therefore, the advantages of Japanese designers are highlighted here. In an interview with Tencent Home, Shuhei Aoyama once said that many Chinese believe that Japanese designers are better at renovation because they "think that Japanese designers can make good use of small space and design better details".

In recent ten years, the aging problem in Japan has become increasingly serious, the population has been decreasing, and there are more and more empty houses, which has prompted architects and designers to shift their attention from building new houses to transforming old ones. A good example is the group land reconstruction project of MUJI in cooperation with Japanese urban institution UR. At that time, Muji’s team of designers transformed a group of "low-rent houses" that were gradually vacant in Japan after World War II into rental houses that met the preferences of young people, making those old houses that were supposed to be eliminated by the times have the meaning of existence again.

In fact, not only architects and designers, but also Japanese people have a lot of experience on how to make effective use of small space. This is largely because Japan has a small land and a large population, and it is popular to live alone. The family size is usually small, so the area of its own house is usually small. However, after experiencing the consumption era in 1980s and 1990s, Japanese people generally have a lot of things at home, which need to be accommodated — — This is why there are all kinds of strange but brain-opening storage techniques and storage tools for sale in Japan.

The process of urbanization and aging in Japan is earlier than that in China. What Japan faced in the past two or three decades is exactly what China is experiencing now.

Since 2000, the urban commercial housing in China has been growing by spurt, which makes the old husbands’ houses that were built and distributed in a unified way and the quadrangles and foreign buildings that have been passed down instantly become anachronistic, and they no longer meet the requirements of the times in terms of apartment type and community facilities. At the same time, the continuous relocation of industrial facilities to the suburbs has also left a large number of almost abandoned old buildings in the city — — Many of these buildings have been demolished, while the remaining buildings, especially those with historical significance or cultural heritage value, are waiting for renovation.

There has been a wave of transformation in the construction industry. Ma Yansong and many other buildings have tried to rebuild the hutong houses in Beijing. In the past two years, Beijing Design Week has been actively carrying out activities around the protection and reconstruction of traditional buildings such as old factories and quadrangles. Naturally, Japanese architects living in China have also caught up with this fashion, and their advantage is the skills and experience accumulated in their hometown.

"There are a large number of old houses with cultural and historical background all over China. After a period of newly developed construction, everyone returned to pay attention to the transformation of old houses, and reappearing the splendor of old buildings is the normal national development order. " Kooo architects Xiao Yan Shen and Xiao Yan Ayaka also told the interface news.

Xiao Yan Shen and Xiao Yan Ayaka recently completed a homestay renovation project in Yuhang District, Hangzhou, Zhejiang. They transformed a multi-storey residential building with China rural characteristics into a water town hotel with white walls and black tiles, making the building return to the appearance of an "ancient house" that is more compatible with the surrounding environment surrounded by green mountains and trees, but does not lose the sense of modern design.

Converting old houses into commercial public buildings is a common means to protect and reuse traditional buildings. The transformation of the whole tourist area of some blocks in Kyoto, Japan is typical. Many places in China have made similar attempts. For example, tourist areas such as Wuzhen and Xitang in Zhejiang, private restaurants in Beijing Hutong and Shanghai Alley, and creative parks in factories such as 798 and 751.

However, similar transformation can easily only stay in the building itself, protecting the formal tradition. Kyoto actually provides a more referential idea, because in addition to retaining the appearance of traditional Japanese-style buildings, the lifestyle and state of Kyoto residents can also be continued and preserved during the transformation process. This state of coexistence and interaction between people and buildings is the most attractive place in Kyoto.

"I think it is wrong to do only formal transformation. I hope that architectural transformation can preserve life itself." Shuhei Aoyama said, "And according to the demand, there are still more houses that need to be rebuilt, because many houses in China are mass-produced when they are designed, without considering the preferences of personal life. Now more and more people want to consider themselves, but they can’t find the right person."

Whether for public use or private residence, the rising demand for housing renovation in China provides more opportunities for Japanese architects and designers who are not dominant in their hometown. However, in comparison, the renovation of residential buildings like Muji and Shuhei Aoyama’s Dream Renovater needs to keep its practical use in life, and it faces greater difficulties, but the impact of the harvest is not as good as that of public projects, so there are not many people who really undertake this kind of civil housing renovation cases in their lives.

The house is for residential purposes, and the renovation will directly affect the lives of the residents, so (designers and teams) have little freedom to play. "Gu Benzhan said that this is the most difficult place in the whole Compact Life transformation.

Shuhei Aoyama’s experience in The Dreamer is the best example of this sentence of Gu Benzhan — — He first had a long and repeated communication with the owner in the program, and fully listened to the needs of the owner. In addition, because the reconstructed house is located in the quadrangle, and there are many public spaces, he also needs to communicate with his neighbors for many rounds. For example, the procedures such as opening the door and opening the window need the consent of the neighbors. However, after the renovation, the design results were still "destroyed", because the owners and neighbors still chose to use the new space in the way of "grounding gas" before the renovation.

This result is actually unexpected. In the face of the owners who have no storage habits before, the transformation of designers with "storage" as the core can only be a wishful effort in the long run. This will be a common phenomenon in China. From this perspective, Japanese designers who are good at making better use of small space through accommodation may not really meet the needs of a large part of China owners. And it is hard to say that such a transformation is good. Several Japanese designers interviewed by us all said that it is desirable to respect the lifestyle of the owners and not impose the wishes of the designers.

Many times, Japanese architects and designers will encounter obstacles from social development and ideological differences.

"Japan did not have the Internet as it does now in the early years of economic development. Therefore, I think that China’s rapid development was influenced by overseas more than that of Japan at that time. At present, the concept of Party A we contact is a very international concept. " The little couple said.

The most obvious manifestation of "internationalization" is that Chinese’s perception of "permanence" may be closer to that of western countries. In the west, a permanent building refers to a stone house that will never be demolished. What it looks like when it is built determines what it looks like later. Chinese’s pursuit of architectural renovation and indoor renovation all want to follow a pattern, just like whether in quadrangles or water towns, when it comes to public renovation of traditional buildings, he always wants to refer to a pattern of filming costume dramas.

This makes Japanese architects and designers who advocate the goal of "permanence" through continuous renovation and reconstruction somewhat uncomfortable.

"Doing the past is not a tradition, but doing what is needed now is to create a tradition, and tradition is not a copy of the past," Shuhei Aoyama explained by taking the work of Japanese temple workers as an example. "Ise Shrine is one of the most important shrines in Japan. There are two plots in the courtyard. The house on the left ground was demolished and rebuilt, so the right one was used. Twenty years later, the right one was demolished, and then the left one was used. In this way, workers can learn at the age of 18, operate at the age of 38, take the lead at the age of 58, and participate in the rebirth of a building three or four times in their lives. Such workers also have continuity. "

For Japanese or other countries’ designers, it is not a difficult problem to transform the building itself. What is difficult is how to keep the original advantages and integrate them into the thinking of China residents.

360 Zhou Hongyi fired again: GPT 6-8 will have a sense of autonomy. Let’s measure right and wrong.

Recently, Zhou Hongyi of 360 said."GPT6 to GPT8 artificial intelligence will generate consciousness and become a new species.In the future, the artificial intelligence big language model may realize self-evolution, automatic system updating and self-upgrading, or exponential evolution ability, and human beings will face unpredictable security challenges. "

Zhou Hongyi, as a "master of tuyeres", has to get involved in almost every tuyere. What he said is somewhat credible, and it is necessary to make a big question mark.

Moreover, Zhou Hongyi only gave a prediction, but did not give his own reasons and reasoning logic.

As a media that focuses on the depth of the industry, we should not stay on the slogan of the headline party, but analyze the problem from a deeper level.

Will GPT grow into a general artificial intelligence model? If so, how long will this process take? Next, we try to discuss this disturbing problem together.

To answer this question, we need to "tear down" a big model like GPT and see what is inside it and how it works.

"Unpack" the black box of the big model

Large model refers to a neural network model with a very large number of parameters, which is usually used to deal with complex natural language processing, image recognition, speech recognition and other tasks. The core elements of the large model are mainly neural network, layer, neuron and parameters.

Data ape mapping

neural network

Neural network is a machine learning algorithm, which is inspired by the nervous system of human brain. It consists of multiple layers, each layer contains multiple neurons, and the connections between layers form a neural network. Each neuron receives the input from the neuron in the upper layer, calculates the output according to its input, and then passes it on to the next layer.

floor

Layer is a part of neural network, which is composed of multiple neurons. Each layer can be configured with different parameters such as activation function and optimizer. Usually, each layer will transform the input and then pass the output to the next layer. Common layers include fully connected layer, convolution layer, pooling layer, etc. The basis for dividing different types of layers is mainly the type of data processed, the internal structure of layers, the functions of layers, etc. For example, the fully connected layer is the simplest and most commonly used layer in neural networks. Its core function is to connect all neurons in the upper layer with all neurons in this layer. This connection allows the neural network to learn the complex nonlinear relationship of input data. Fully connected layer is usually used for image classification, speech recognition, natural language processing and other tasks; Convolution layer is the core layer of Convolution Neural Network (CNN), which is used to process data with spatial structure, such as images. Its core function is to perform convolution operation on the input data through a set of learnable convolution kernels to extract the features of the input data. The internal structure of convolution layer includes several convolution kernels and a bias term, and the output of convolution layer is usually input into pooling layer.

neuron

Neurons are the basic units in neural networks,Its main function is to receive signals from neurons in the input layer or the previous layer and generate output signals. The inputs of neurons are transmitted through a set of weighted connections and are weighted and summed in neurons. Then, this sum is input into the activation function for nonlinear transformation to produce the output of neurons.

The core of neuron is activation function, which is the core component of neuron processing input signal. Neurons receive input signals, sum them with weights, and then input them into the activation function for nonlinear transformation.The function of activation function is to introduce nonlinear factors into neurons, so that neurons can learn nonlinear models, thus improving the expression ability of models.

parameter

Parameters refer to variables in the neural network, which will be updated with the training of the neural network.Each neuron has a weight vector and an offset term, which are usually called parameters.The values of these parameters will be updated by the optimizer during training to make the output of the neural network as close as possible to the expected output.

To sum up, neurons are components of layers, and layers are components of neural networks. Parameters are stored in neurons, and each neuron has a set of parameters (weights and offsets). During the training process, the optimizer will update these parameters to make the output of the neural network as close as possible to the expected output.

So, how do neural networks, layers, neurons and parameters work systematically?

Next, we take the training process of GPT-4 as an example to illustrate the cooperation process of different elements in the training process of large model, specifically:

1) Firstly, all parameters of GPT-4 model are randomly initialized, including the weight and deviation of each neuron in the neural network.

2) Prepare data sets, which can be marked texts, such as articles, novels, papers, social media posts, etc. Before training, data must be preprocessed and cleaned up, such as deleting special characters, stop words and other irrelevant information.

3) Training data will be divided into several small batches, usually each batch contains hundreds to thousands of text samples. Input each batch into GPT-4 model, and the model will calculate the output according to the current parameters, that is, predict the probability distribution of the next word.

4) Calculate the loss function of the model, which can reflect the performance of the model on the training set. In the case of language model, cross entropy is usually used as the loss function.

5) Calculate the gradient of parameters according to the backpropagation algorithm, and the gradient reflects the change rate of the loss function of the model at a certain point. Then use the optimizer to update the parameters of the model to reduce the loss function.

6) Repeat steps 3-5 until the performance of the model reaches the expectation or the training time is exhausted.

Kind of like the human brain.

From the above analysis, we can see that the big model is trying to simulate the working mechanism of the human brain. In fact, at present, human beings are the only intelligent creatures. If a large model is as intelligent as human beings, "bionic" is the best way.

Next, let’s briefly sort out the structure and working mechanism of the human brain, and then compare the structure and working mechanism of the big model with that of the human brain.

Let’s first look at the structure of the human brain.

The human brain is a neural network system composed of tens of billions of neurons, and neurons are the basic units of neural networks. Each neuron is connected with each other by synapses, which are the basic channels for transmitting information between neurons.

The core function of neurons is to receive, process and transmit information.A neuron usually consists of three parts: cell body, dendrite and axon.Neurons receive signals from other neurons and transmit them to the cell body through dendrites. The cell body processes these signals and generates output signals, which are transmitted to other neurons through axons.

The connection between neurons is usually realized through synapses. Synapses are divided into chemical synapses and electrical synapses. Chemical synapses transmit signals through neurotransmitters, while electrical synapses transmit information directly through electrical signals.

The human brain is composed of a large number of neurons and synapses, which are connected together according to specific laws to form different neural circuits and neural networks. These neural circuits and neural networks work together to complete various complex cognitive, perceptual, emotional and behavioral activities of the human body.

Through the above analysis, we can make an analogy between the human brain and various elements of the big model, as shown in the following table:

The layer in the big model can be compared with the cortex in the human brain.The layer of the large model is composed of several neurons, each neuron receives the output of the previous layer as input, and calculates it through the activation function to produce the output of this layer. The cerebral cortex is a complex network composed of neurons and synapses, in which each neuron also receives the output of other neurons as input, and transmits and processes information at synapses through chemical signals.

Neurons in the large model can be compared with neurons in the human brain.They are the basic computing units in the network, which receive input signals and process them through activation functions to generate output signals. Neurons in the human brain are the basic computing units in organisms. They connect with other neurons through synapses, receive chemical signals from other neurons, and generate output signals through electrical signals.

The parameters of the large model can be compared with the synaptic weights in the human brain, which determine the intensity and mode of information transmission between neurons. Synaptic weights in the human brain also play a similar role, which determines the connection strength between neurons and the signal transmission mode at synapses.

Quantitative comparison between large model and human brain

The above is only from a qualitative point of view, to understand the big model, the working mechanism of the human brain, and to make an analogy to their core elements.

Quantitative change leads to qualitative change, even if it is similar in structure, but the difference in quantity often leads to great difference.

Next, let’s compare the big model with the human brain from a quantitative point of view.

The following are the approximate values of the total number of neural layers and parameters of GPT-1 to GPT-3.5 models (the number of neurons is not disclosed, and GPT-4 does not disclose relevant data):

Then, let’s look at the number of neurons and synapses in the human brain. In order to make the results more referential, besides humans, we also selected monkeys, dolphins, cats and ants. The specific results are as follows:

From the above analysis, we know that the neurons of the large model can be classified as human neurons, and the parameters of the large model can be classified as synapses of the human brain. But unfortunately, the big models in the industry rarely disclose the number of neurons, but generally disclose the size of parameters. Therefore, we compare the parameter scale of GPT series large models with the synaptic scale of human, monkey, dolphin and cat brains:

From the above table, it can be seen that the "intelligence" level of GPT-3.5 has fallen within the intelligence range of monkeys, which is 285.7-2857 times worse than that of human beings.

On the other hand, from the evolution speed of GPT itself, the parameter scale can be increased by two orders of magnitude in the first two iterations, but after GPT-3, the speed of parameter scale increase is greatly reduced. Assuming that the parameter scale of GPT will increase by five times in each iteration, after five iterations (the fifth power of five is 3125), that is, GPT-9, its "intelligence level" may catch up with human beings.

Of course, the above inference is only a simple model, and there is an assumption that the intelligence level is positively related to the size of synapses (parameters). But whether this hypothesis can be established needs a big question mark.

Compared with synapses, neurons are a better indicator of intelligence. Judging from the current situation, the information processing ability of the activation function of the large model is far weaker than that of human brain neurons. The activation function of large model neurons is relatively simple. For example, the neurons of Sigmoid activation function have a smooth S-shaped curve in the output range, which can realize tasks such as binary classification, and the neurons of ReLU activation function have nonlinear modified linear properties. Relatively speaking,The neuron of the human brain is a biological cell, and its information processing ability is definitely far beyond a simple mathematical function. Therefore, even if the number of neurons in the large model catches up with the level of the human brain and reaches hundreds of billions (the corresponding parameter scale exceeds 1000 trillion), its intelligence level cannot be compared with that of the human brain.

In addition, the neural network of the large model can be compared with the neural network of the human brain, but their implementation methods are completely different. The neural network of large model simulates the connection and information transmission between neurons through mathematical model, while the neural network of human brain is a complex structure composed of neurons, synapses and other biological elements. In addition,The connections between neurons in the neural network of human brain are very complicated, and they can freely establish, dismantle and adjust the connections, while the neural network of large model is set in advance.

At present, human beings are still relatively "safe". But let’s not forget,The size of neurons in the human brain is almost constant, while the size of neurons and parameters in the large model is increasing exponentially.According to this trend, it may be only a matter of time before the intelligence level of large models catches up with human beings.

Hinton, a great god in the field of artificial intelligence, said, "The development of general artificial intelligence is much faster than people think. Until recently, I thought it would take about 20-50 years for us to realize universal artificial intelligence. Now, the realization of general artificial intelligence may take 20 years or less. "

In the face of general artificial intelligence or even super artificial intelligence, human psychology is complex. On the one hand, it is hoped that there will be more intelligent systems to help mankind complete more work and liberate productive forces; On the other hand, I am afraid to open Pandora’s box and release a monster more terrible than nuclear weapons.

I hope that even if we create a "god", it will be a god full of love, not a god who regards human beings as ants!

Text: A misty rain/data ape

The back of the shopping receipt is stamped with the "exemption" seal, so can the supermarket really be exempted?

  Is it stamped?

  The relevant person in charge of the supermarket said that there are many professional counterfeiters recently, and their counterfeiting is not formal, but the goods are switched and stolen. In order to avoid the situation that the professional counterfeiters can’t define the goods by changing the package, so when paying the bill at the cashier, the receipt is stamped.

  Any tips?

  The reporter noticed that the cashier didn’t give any tips before stamping the receipt, and the stamp on the back of the receipt was "Xinhua Store confirmed that the goods had not passed the shelf life when shopping". The cashier stamped each customer’s shopping receipt, and the customers hardly noticed it.

  Is there something fishy?

  The lawyer said that the act of stamping the small ticket is that the supermarket pushes the responsibility to the consumer, which unduly increases the responsibility of the consumer. If consumers buy goods for a long time, it is difficult to prove, and the stamped receipt is more conducive to the supermarket to prove that they have not sold expired goods.

  When buying goods in the supermarket, have you ever noticed the cashier’s receipt handed over by the cashier and the goods? On July 13th, Mr. Zhou, a citizen who often shops in Renrenle Supermarket (Xinhua Store) and has the habit of keeping shopping receipts, suddenly found that there was a little more on the receipts than before.

  It turned out that after shopping in the supermarket, the cashier stamped a seal on Mr. Zhou’s cashier’s receipt, "It was confirmed that the goods had not passed the shelf life when shopping." Mr. Zhou believed that the supermarket did not make a public notice of this requirement beforehand, which was a voluntary exemption and actually harmed the legitimate rights and interests of consumers.

  In this regard, the relevant person in charge of the supermarket explained that the move was mainly to prevent professional counterfeiters from bringing expired food that does not belong to the supermarket into the supermarket in the form of "package transfer".

  Customer query

  Stamping is a unilateral exemption for supermarkets.

  On July 13th, after shopping in Renrenle Supermarket (Xinhua Store), Mr. Zhou, a citizen of Chengdu, accidentally found a red seal on the back of the shopping receipt with the words "It was confirmed that the goods had not passed the shelf life when shopping". Mr. Zhou told Chengdu Business Daily-Red Star News reporter that he is a frequent visitor to this Renren Le supermarket, and he usually has the habit of keeping shopping receipts. This time, he found "different" behind the receipts.

  In order to verify whether the store acted unilaterally or other Renrenle supermarkets had this provision, on July 15th, Mr. Zhou bought goods at Renrenle Supermarket (Qianfeng Store). This time, the back of the shopping receipt was not stamped. On the same day, Mr. Zhou came to Renrenle Supermarket (Xinhua Store) again. This time, he noticed that when checking out at the cashier, the cashier stamped the back of the printed receipt.

  In this regard, Mr. Zhou believes that the supermarket has not made relevant public announcements to inform consumers before, which belongs to the unilateral exemption of the supermarket, which actually damages the consumers’ right to know and the rights to legally defend their rights.

  Journalist visit

  There is no hint before stamping.

  On July 16th, a reporter from Chengdu Business Daily-Red Star came to Renrenle Supermarket (Xinhua Store) and found a seal with a red background on each checkout counter. After other consumers settled the bill, the cashier stamped the receipt. No consumer objected to this behavior, and some even didn’t take the receipt away.

  The reporter bought a drink as a consumer. When checking out, the reporter noticed that the cashier didn’t give any hint before stamping the receipt. The stamp on the back of the receipt was "Xinhua Store confirmed that the goods had not passed the shelf life when shopping". The reporter saw at the scene that the cashier had stamped each customer’s shopping receipt, and the customers were almost unaware of it.

  Later, the reporter visited other stores of Renren Le Supermarket, but did not find the act of stamping the back of the shopping receipt.

  Supermarket response

  Prevent professional counterfeiters from cheating.

  "Mainly to prevent professional counterfeiting, there is nothing for other (customers)." The relevant person in charge of the customer service department of Renrenle Supermarket (Xinhua Store) explained that because there are so many professional counterfeiters in the supermarket recently, their counterfeiting is not formal, but the goods are switched and stolen. In order to avoid the situation that the professional counterfeiters can’t define the goods because they switch packages, so when paying the bill at the checkout counter, they stamp the receipt and take it back after the goods are sold, saying that it has expired. The supermarket is not responsible. "We also have a reminder on the radio, which is broadcast once every half hour, so that everyone can pay attention to the shelf life and collect shopping receipts." The person in charge said that the supermarket has fulfilled its obligation to inform.

  Subsequently, Mr. Tan, the person in charge of Renrenle Supermarket in Chengdu, contacted the reporter and explained that a warm reminder was posted in the eye-catching position of the supermarket: "This mall refuses to sell expired goods, please tell the employees of this mall if you find it", which is also to provide customers with quality goods. The act of stamping the official seal is to confirm with the customer (check the shelf life of the goods) and also to consider the safety and health of the customer. At the same time, it is also a kind of protection for both parties to confirm with consumers whether the goods have expired because of the behavior of professional counterfeiters "switching packages".

  Mr. Tan also said that everyone in the city has this initiative, which started three months ago. However, the reporter suggested that the visit found that only Xinhua Store used the stamp method, and the other party asked which supermarkets needed to assess the service quality.

  Lawyer’s statement

  Stamping is an act of shirking responsibility.

  Liu Xiu, a lawyer of Taihetai Law Firm, believes that supermarkets have a substantive obligation to review whether the goods they sell have passed the shelf life, and consumers have no obligation to review and confirm. (The act of stamping the receipt) is that the supermarket pushes the responsibility to consumers, which unduly increases the responsibility of consumers. Consumers usually don’t pay attention to the tips on the product receipt. If consumers find that the product has expired after returning home, even if they stamp it, they can’t be exempted from the responsibility of the supermarket.

  Xing Lianchao, a lawyer of Sichuan and Law Firm, believes that supermarkets should stamp the cashier’s receipt with the seal of "Confirmed that the shelf life has not expired", so both parties should confirm the goods sold on the spot before checkout to avoid disputes in the future. If there is no confirmation behavior, it will be wrong for the operator to stamp it directly.

  Generally speaking, by comparing the shopping receipt and date of purchase with the shelf life of the goods, we can find out whether the goods have expired after purchase. If it is said that consumers spend too long buying goods, it is difficult to prove, and a small receipt with a seal is more conducive to the supermarket to prove that they have not sold expired goods, and consumers need to prove.

It is expected that the return flow of visiting relatives, the flow of working in the south, the flow of students and the flow of working in the north will be staggered in turn.

In Spring Festival travel rush this year, the station has set up green channels for verification and security inspection at each entrance, and emergency passengers who arrive 15 minutes before driving will be given priority security inspection by volunteers.

In addition, the station organizes party member, youth commandos and volunteers to provide service guidance in key parts such as the waiting room, ticket office and service desk to ensure the safety of passengers’ travel and the waiting order.

To this end, the station has successively opened manual ticket sales windows, expanded online and self-service ticket sales channels, and provided convenient ticket purchase services for passengers.

"During the peak passenger flow period, we will also temporarily adjust the departure area of some line buses to realize the orderly diversion of passengers and ease the operating pressure of the ticket office, waiting room and parking space." You Wu said that the station will dynamically allocate capacity through reasonable arrangement of flights to ensure that passengers queue less, get tickets, take cars and get home.

The airport sets up a special check-in counter for urgent and special passengers.

On January 13th, the reporter saw in T3A Terminal of Chongqing Jiangbei International Airport that three staff members wearing beige coats and ribbons were helping the check-in passengers. Their ribbons are printed with the words "urgent passengers, let me help you".

Let historical documents "live" on campus. This ideological and political course is very informative.

Recently, the investigation team of folk historical documents from the School of Economics of Tianjin Normal University entered the Tianjin Tourism Foreign Affairs Vocational High School in Jinnan District, and brought the ideological and political practice class with the theme of "protecting memory and inheriting civilization" to the students of four classes.

In the class, the members of the investigation team showed the folk literature excavated from more than 130 villages in Beijing, Tianjin and Hebei over the years, including the bridge-building tablets in Daoguang period of Qing Dynasty, the commercial account books in Guangxu period, and the land contracts in the Republic of China. Members walked into the middle of the students and explained the story of rescuing these documents and the history behind them. Zhang Zhihe, a teacher led by the investigation team, said: "We hope that through the integrated ideological and political courses, including some exhibitions and community presentations, the folk historical documents we have studied can be’ alive’, and we can truly and practically come to our classmates and the masses, so that everyone can feel the history and culture together and inherit the history and culture." ?

Walking into the high school classroom with a wooden box of folk literature and materials, turning academic achievements into vivid teaching materials, this ideological and political lesson is both interesting and "informative". Student Yang Yaqi said: "This ideological and political course has a strong sense of participation. Through the teachers’ explanations, I not only felt the thickness of history, but also felt the temperature contained in it."

The integrated ideological and political course not only broadens students’ horizons, but also encourages the sharing of resources between schools and the reference of teaching methods. An Zhiquan, secretary of the Party Committee of Tianjin Tourism Foreign Affairs Vocational High School, said that he would actively explore and make use of inter-school cooperation to enhance the charm of the ideological and political class, guide students to understand the feelings of home and country from traditional culture, and establish a correct outlook on life and values.
