Many problems with the ankle are related to wearing shoes. What should we pay attention to when choosing shoes？

　　Health is an inevitable requirement to promote people’s all-round development, and it is also the common pursuit of the broad masses of the people. At present, with the continuous improvement of people’s health awareness, more and more people realize the importance of sports and actively participate in various sports. However, in the process of exercise, many people have done some damage to their bodies due to lack of knowledge and blind pursuit of exercise. This edition invites experts to explain the injuries that are easily overlooked in life.

　　As the saying goes, "A journey of a thousand miles begins with a single step", and ankle health is the foundation of human standing and sports. However, about a quarter of the people in the world are suffering from ankle diseases to varying degrees. However, due to the hidden symptoms of foot diseases, it is easy to be ignored and delay treatment, thus affecting the quality of life.

　　1. Most ankle diseases are acquired.

　　Bipedal is called the second heart of human body, which is very important to human body.

　　Although the ankle is only a small part of our whole body in terms of volume, and the area of joint contact is much smaller than that of knee joint or hip joint, the ankle bears the weight of our whole body, which will inevitably lead to higher local pressure of joints than other joints, and it is more prone to injury.

　　Foot and ankle is an extremely complex structure, including foot and ankle, and foot is divided into three parts: forefoot, middle foot and hind foot. A small ankle part, the bones alone involve tibia, fibula, and tarsal bones 7, metatarsal bones 5 and toe bones 14, a total of 28. It’s more complicated in terms of joints. Besides the ankle joints (tibiofibular joint, tibiofibular joint and talofibular joint) that we all know, there are tarsal joints such as talocalcaneal joint, talocalcaneal joint, calcaneal roll, cuneiform joint, cuneiform roll and cuneiform roll, tarsometatarsal joint, metatarsal joint, metatarsophalangeal joint and interphalangeal joint. From the research field, it includes ankle trauma, podiatry and orthopedics. It should be emphasized that apart from congenital factors, such as congenital clubfoot and flatfoot, most ankle diseases are acquired, such as ankle ligament injury and heel pain.

　　Due to the extremely complex structure of the ankle, many kinds of diseases in each part, and the strength of our whole body in daily life, these factors make our ankle more prone to problems, and the ankle problem is more difficult to treat. Excessive exercise and trauma can cause various ankle diseases, especially ankle sprain, which accounts for 40% of sports injuries. It can be seen that ankle disease is a big problem, and what is most closely related to people, but most easily overlooked, is how to wear shoes.

　　2. Many problems with ankles are related to wearing shoes.

　　Speaking of it, people have been wearing shoes since they learned to walk. Can’t they choose shoes? In fact, most people may not know that many problems with ankles are related to wearing shoes.

　　Bad shoes not only easily cause ligament damage, but also easily lead to many diseases in the ankle. A typical example is that many women who love beauty often wear high heels to cause foot pain. Different heel heights will lead to different forces on the forefoot when walking. The higher the heel, the greater the pressure on the forefoot and the worse the stability when walking, which will cause forefoot pain. At the same time, most of the high-heeled shoes are pointed leather shoes, and when they are worn, they squeeze into the big toe, which is easy to cause the big toe to valgus, which in turn causes the lateral arch of the forefoot of the second to fifth toes to sink, further causing forefoot pain. Overloading the forefoot for a long time will also cause some foot diseases or appearance changes, such as metatarsalgia and Morton’s disease, which are related to wearing high heels for a long time. In addition, the heel of high-heeled shoes is generally thin, which will reduce the stability of the back of the ankle when worn, so it is easy to cause ankle sprain. Therefore, in life, if female friends like to wear high heels very much, it is suggested to choose a high-heeled shoe with low heels and a slightly wider forefoot design. It would be better if we can strengthen the muscle strength of the calf, which will help to increase the stability of walking in high heels.

　　3. What should I pay attention to when choosing shoes?

　　● You can’t have only one pair of sports shoes. What kind of sports shoes should you wear?

　　Although we all know that we should wear sports shoes when exercising. However, it needs to be reminded that no sports shoes can be suitable for all sports. For example, basketball shoes for playing basketball require a thicker sole, a flatter overall, and a higher upper at the back to prevent sprains and slips. Football shoes running on the grass require more flexible ankle movements and lower uppers. The ground where tennis is played is usually hard, which requires shoes to have anti-slip cushioning effect. Jogging, on the other hand, requires slightly lighter jogging shoes with shock-absorbing air cushions. People who exercise regularly must prepare shoes for the corresponding sports.

　　● It is necessary to cut the shoes properly, not to cut the shoes properly.

　　Everyone looks different, and the 28 bones of the ankle are naturally different. It can be said that billions of us can’t find the same feet. To a large extent, the arch of the foot is high and low, and the feet are wide, narrow and fat, all of which need special attention when choosing shoes. For example, people with flat feet have poor cushioning when walking with load, and their feet will hurt when walking too much, so try to choose shoes with raised arch pads. Some people have wide toes, or have eversion, so they should choose loose toes, otherwise it will cause wear between toes, and long-term walking will cause pain. In addition, people with heavy weight should choose elastic shoes when choosing shoes to reduce the impact of walking on the soles of their feet.

　　● Older people choose shoes not as soft as possible.

　　With the increase of age, the fascia and ligament of the ankle will also age, and the bones and joints will also undergo degenerative changes. Compared with young people, the ankles of the elderly are more vulnerable to injury, and the speed of recovery after injury will be much slower than that of young people. Therefore, the elderly should pay more attention to the choice of shoes. A common misconception is that the elderly like to wear soft-soled cloth shoes, and feel that the softer the better. In fact, too soft soles can’t give enough support to the soles of the feet, and at the same time, too soft shoes can’t provide good elastic cushioning, which will increase the damage to the soles of the feet. Old people should choose shoes with sufficient cushioning and good elasticity. The part of the insole that directly contacts the foot surface is also required to be relatively soft and fully fit to the sole of the foot. In addition, if the blood circulation of the soles of the feet of the elderly is poor, they should choose looser shoes. The requirement is not only that there is no squeezing and grinding of the feet when trying on, but also that there is no grinding of the feet when the feet are slightly swollen.

　　● Good-looking and expensive shoes are not necessarily suitable shoes.

　　In modern society, shoes are not only a tool to protect the body from cold, but also an aesthetic requirement and even a symbol of identity. Some shoes are worth several thousand yuan or even ten thousand yuan. However, it needs to be reminded that no matter how beautiful shoes are, you can’t have them if they are not suitable for your feet. Just as many women will find that wearing high heels can cause foot pain, sometimes, expensive shoes are not necessarily suitable shoes. For example, for patients with lateral ankle ligament injury, it is recommended to wear some high-top shoes. This is because a higher upper can provide stability to the ankle joint and reduce the occurrence of sprained ankle. For patients with hallux valgus, when choosing shoes, we should try to reduce the pressure on the forefoot and try to avoid wearing high heels. Similarly, women who often sprain their ankles should wear less high heels, especially those with extremely high heels. Because when wearing high heels, our ankles are in a "plantar flexion" position, which is relatively loose, and thin high heels are not easy to stabilize, which will increase the chance of spraining our ankles.

　　● Don’t wait for the soles to wear out before changing shoes.

　　Although we advocate hard work and simplicity, from the point of view of protecting ankles, don’t wait for the soles to wear out before changing shoes. From the above, I believe everyone already knows that everyone’s feet are different. A pair of suitable shoes needs to have a high fit with your feet. When the sole of a pair of shoes is worn thin, the shape of the shoes changes accordingly. At this time, these shoes are no longer suitable for you and need to be replaced. In life, we often find that a pair of shoes are always worn in a certain part. For example, sometimes, the inside of the heel is worn thin, and other places are fine. In this case, many people are reluctant to change their shoes. But in fact, in layman’s terms, it is this worn-out sole that replaces our feet to bear the damage caused by walking. If it is not replaced in time, it will be our feet that will be damaged next.

　　● Foot pain must not be tolerated, and timely medical treatment is the key.

　　Ankle is a complex structure, and everything can’t be done just by choosing the right shoes. Once there is pain in the foot, you should see an ankle specialist in time. What needs to be understood is that many diseases of the ankle need surgical treatment, and there are still many diseases of the ankle that need standardized rehabilitation training, so I hope everyone will not be careless, so as not to delay the treatment and bring serious consequences.

Decode the ＂end-to-end＂ concept that everyone is talking about, and easily play with the new trend of automotive technology.

Since the launch of the end-to-end intelligent driving system "FSD V12 beta" in the United States in August 2023, end-to-end has become the hottest topic in the automobile industry. With the follow-up of Huawei, Tucki, Weilai, Ideality and other enterprises, almost every domestic manufacturer will spend a lot of space in the press conference to publicize how powerful their end-to-end is. Regardless of marketing methods, what does "end-to-end" mean? What does it mean for intelligent driving? Today we will explain this question to you!

Before the end-to-end intelligent driving system was mass-produced, every intelligent driving system adopted a modular scheme. Simply put, modular intelligent driving is an assembly line, which mainly includes four processes: perception, prediction, planning and control. First of all, the task of the sensing part is to process the data of sensors such as radar and camera of the vehicle, and then analyze the specific position and road trajectory of the objects around the vehicle, and distinguish whether they are pedestrians, bicycles, cars or trucks.

Then, the perception module will transmit the above information to the prediction module, and the prediction module will analyze the next movement state of the surrounding traffic participants according to the above information, such as whether the surrounding vehicles will turn, go straight or stop next. After further analysis, the prediction module will provide one or more driving paths and vehicle speeds that the vehicle can refer to next.

Then the prediction module sends the road driving scheme of the vehicle to the planning module, and the planning module will decide what the vehicle should do next according to the information such as the vehicle’s own state and navigation. After the planning module confirms the driving path and speed, it will transmit the command to the control module, and then the control module will calculate and operate the steering wheel, brake and throttle of the vehicle. A seemingly simple intelligent driving function is realized through the above steps.

From the above introduction, it is not difficult to see that modular intelligent driving decomposes simple driving behavior into multiple steps, and the logic of each step is in perfect harmony. In the eyes of car companies and suppliers, modular intelligent driving itself is a very good solution, because different teams can be responsible for the corresponding modules and give full play to the advantages of division of labor and cooperation, thus rapidly changing intelligent driving from concept to mass production.

Secondly, modular intelligent driving has a set of system framework with clear functions and responsibilities, so when the intelligent driving system finds bugs in use, car companies and suppliers can immediately find the specific reasons for the bugs and quickly fix them through OTA. For example, if the vehicle brakes wrongly when driving at high speed, then through data analysis, the vehicle enterprise can know whether the fault is due to the wrong data of the sensing module or the wrong judgment given by the forecasting and planning module.

Although modular intelligent driving is convenient for mass production and BUG repair, it needs to learn a lot of traffic rules and driving experience if it wants to control vehicles like people, and all this depends on engineers to define the rules in advance, that is, to turn traffic rules and driving experience into lines of software code. But can engineers write code to cover all the driving scenes in reality? Of course it’s impossible! On this issue, there is a classic case in the industry. If you drive a vehicle on a narrow road full of cars on both sides, a balloon suddenly floats on one side of the road, then the general logic will think that there may be children jumping out on one side of the road, so the vehicle should brake immediately. However, the same scene is placed on the high speed. If the intelligent driving system still controls the vehicle by braking immediately, it is likely to turn into a rear-end collision. In other words, if engineers don’t define the rules in advance for this kind of driving scene, such as the system doesn’t brake after the balloon is detected at high speed, then the intelligent driving system will have safety risks when it encounters similar scenes.

According to Xpeng Motors, a relatively stable mass production intelligent driving system has about 100,000 rules. And if the intelligent driving system is to be close to the same level as people, it needs to manually write about 1 billion rules. For software engineering development, this is almost impossible. Because of this, we can see that the traditional intelligent driving system will make more or less mistakes in daily use, so that drivers have to intervene.

For the above reasons, car companies that focus on autonomous driving have been trying to solve the problem that traditional intelligent driving needs preset rules, so there is an end-to-end approach. The so-called end-to-end, in fact, is to make all the traditional sub-modules of perception-prediction-planning-control neural network, that is, to replace the traditional algorithms and manually written rules with advanced algorithm models.

Therefore, the end-to-end workflow is quite different from the traditional modular workflow. The traditional modular work sequence is perception-prediction-planning-control in turn, while the end-to-end sequence is sensor data (radar, camera)-neural network-driving parameters (steering wheel, throttle, brake), that is to say, the traditional perception, prediction, planning and control modules are all completed by neural network.

As can be seen from the workflow, the core technology in end-to-end is neural network, and the technology most closely related to neural network is AI. In the past two years, AI has shown great performance in the fields of voice, text, pictures and video, and everyone should have realized it. When the neural network is applied to the car, it means that people can constantly train the intelligent driving system, so that it can learn to adapt to more complex driving environment.

Therefore, at the functional level, the biggest change from end to end is that the system has the ability of autonomous learning, which is a function that traditional modular intelligent driving does not have.In this way, when dealing with all kinds of unexpected real driving scenes, end-to-end can calculate the appropriate rules through neural network, without having to manually write the rules in advance, which also provides a solution for intelligent driving to deal with endless driving scenes in reality.For example, the Tesla FSD V11 version, which didn’t have end-to-end function before, has written more than 300,000 lines of code, while the end-to-end FSD V12 version has directly reduced more than 300,000 lines of code to 2,000 lines, but the performance of FSD V12 is closer to human drivers than V11.

fromIn theory, end-to-end is indeed a very ideal technology, but in practice, end-to-end is not so reliable. This is because people’s understanding of neural networks is still not clear enough at this stage, so people also call neural networks "black boxes". As shown in the above figure, in the white box state, we are very aware of the logical causal relationship between system input/output, but when the input information passes through the black box, people can’t explain why the input information becomes the output information.

For example, when there is an obvious logical error in the intelligent driving system, the vehicle manufacturer can quickly find out which module the problem is, and then manually write a new rule. But in the end-to-end system, car companies do not know which parameter or structure in the complex neural network has problems.

For this reason, the end-to-end intelligent driving system based on neural network can sometimes give reasonable rules in very complicated scenes, but sometimes it will make very low-level mistakes, such as not being able to distinguish traffic lights, so some people describe it as "the upper limit is very high and the lower limit is very low". Considering that there are some risks in the end-to-end application, the end-to-end intelligent driving system introduced by Huawei and Tucki does not rely entirely on autonomous learning, and their end-to-end systems still have many manually written rules to cover the intelligent driving system.

From the perspective of technology development trend, end-to-end is definitely the direction of high-level intelligent driving in the future. However, because people’s understanding of neural networks is not thorough enough, the end-to-end performance of various companies at this stage still has a certain gap with the ideal level. In addition, compared with the existing modular intelligent driving system, whether the end-to-end neural network algorithm model is smart or not depends heavily on massive real data for training. Only after massive data training, the neural network can be transformed from a small model to a usable large model, which means that high-order intelligent driving requires huge computing power and data input in the development stage, thus invisibly raising the threshold of intelligent driving. Because of this, some car owners will feedback that their cars are not as good as they used to be after upgrading to end-to-end intelligent driving. This is the painful period of big model training. Considering that there are great differences in end-to-end training among different brands in reality, this means that the performance gap of different brands of intelligent driving systems may be gradually widened in the future.

Six departments： new teachers in colleges and universities can only take up their posts if they pass the examination of teachers’ morality and style.

　　　　　 BEIJING, Jan. 27 (Xinhua) According to the website of the Ministry of Education, recently, the Ministry of Education and the Central Organization Department issued the Guiding Opinions on Strengthening the Construction and Reform of College Teachers in the New Era (hereinafter referred to as the Guiding Opinions). The Guiding Opinions put forward that in order to strengthen the implementation of the evaluation of teachers’ morality, new teachers in colleges and universities must receive special training on teachers’ morality and style before taking up their posts, and only after reaching a certain number of hours and passing the examination can they obtain the qualifications of teachers in colleges and universities and take up their posts to teach.

　　In order to thoroughly implement the Opinions on Comprehensively Deepening the Reform of Teaching Staff Construction in the New Era and the Overall Plan for Deepening the Reform of Education Evaluation in the New Era issued by the Central Committee of the Communist Party of China and the State Council, and strengthen the reform of teaching staff construction in colleges and universities in the new era, the following guiding opinions are put forward:

　　First, accurately grasp the requirements of the times for the reform of teaching staff construction in colleges and universities, and implement the fundamental task of cultivating people by virtue. The goal and task is that through a series of reform measures, the development support system for college teachers is more perfect, the management evaluation system is more scientific, the treatment guarantee mechanism is more perfect, and the governance system and governance capacity of teachers are modernized.

Improve teachers’ theoretical learning system, and comprehensively improve teachers’ ideological and political quality and moral education ability. Strengthen the ideological and political construction of private colleges and universities, and equip and strengthen the ideological and political work team of private colleges and universities.

　　Cultivate and carry forward noble teachers’ morality. Normalization will promote the cultivation of teachers’ morality, and all kinds of teachers’ morality norms will be included in the compulsory content of pre-job training for new teachers and full-time training for in-service teachers. Innovate the way of teachers’ morality education, and stimulate teachers’ endogenous motivation to cultivate teachers’ morality through example leading, situational experience, practical education and teacher-student interaction. Strengthen the "Four History" education of college teachers, standardize the requirements of class hours, and achieve full coverage of all staff in a certain period. Build a good base of teachers’ morality and build a curriculum system of teachers’ morality education. Strengthen teachers’ commendation and improve the teacher honor system. Colleges and universities can hold teachers’ induction and retirement ceremonies, and set up teaching-oriented awards to encourage teachers to concentrate on educating people. Encourage social organizations and individuals to contribute funds to reward teachers. Support local and universities to establish excellent teachers’ libraries, tap typical examples, and strengthen publicity and inspiration. Continue to launch film and television literary works with distinctive themes and showing the style of the teacher era.

　　Strengthen the implementation of teacher’s ethics evaluation. Take teachers’ morality and style as the primary requirement and the first standard in teacher recruitment and introduction, professional title evaluation, post employment, tutor selection, evaluation and reward, employment period assessment, project declaration, etc., strictly assess teachers’ morality, and pay attention to the use of teachers’ morality assessment results. New teachers in colleges and universities must receive special training on teachers’ morality and style before taking up their posts, and only after reaching a certain number of hours and passing the examination can they obtain the qualifications of teachers in colleges and universities and take up their posts to teach. Effectively implement the main responsibility and take the construction of teachers’ morality and style as an important part of the annual assessment of the leading bodies in colleges and universities. Implement the "Ten Codes of Professional Conduct for College Teachers in the New Era" and seriously investigate and deal with the problem of teachers’ moral anomie according to the law and regulations. Establish and improve the exposure mechanism of teachers’ morality violations, and play a warning and shocking role. Relying on the national criminal information database established by political and legal organs, we will establish a system of employment restriction in the education industry.

　　The third is to build a platform for the development of teachers in colleges and universities, and strive to improve teachers’ professional quality and ability.

　　Improve the teacher development system in colleges and universities. Colleges and universities should improve the teacher development system, improve the teacher development training system, security system, incentive system and supervision system, and create a benign environment conducive to the sustainable development of teachers. Actively respond to the challenge of new science and technology to personnel training and improve teachers’ ability to improve teaching by using information technology. Encourage and support college teachers to visit and study at home and abroad and participate in international exchanges and cooperation. Continue to implement the demonstration training project for young teachers in colleges and universities and the construction project of teaching innovation team for higher vocational teachers. Explore the management of teachers’ training credits, and incorporate training credits into teachers’ assessment.

　　Consolidate the development support service system for college teachers. Coordinate the responsibilities of teacher training, career development consultation, education and teaching guidance, academic development, and learning resource services, build a platform such as a strong teacher development center, and improve the teacher development organization system. Colleges and universities should strengthen the development of teachers and the professionalization of personnel, increase the investment in personnel, funds, venues and other resources for teacher development, and promote the construction of demonstration teacher development centers at all levels. Encourage universities and large and medium-sized enterprises and institutions to build teacher training bases, support the exchange and integration of professional teachers in colleges and universities and talent teams in industry enterprises, and enhance teachers’ practical ability and innovation ability. Give play to the exemplary role of famous teachers and teaching achievement awards.

　　The fourth is to improve the management system of teachers in modern universities and stimulate the innovative vitality of teachers.

　　Improve the employment mechanism of college teachers. Fully implement the autonomy of employing people in colleges and universities, and the relevant government departments do not uniformly organize the employment examination for college personnel, simplifying the entry procedures. In accordance with the relevant provisions of the state and the actual needs of running a school, colleges and universities independently formulate the employment conditions of teachers and recruit teachers openly. The graduation institution, study experience abroad, study methods, papers and patents shall not be taken as restrictive conditions. Strictly control the selection and employment of college teachers, and implement the dual inspection of ideological and political quality and professional ability. Establish a system linking the pre-job training of new teachers with the qualifications of college teachers. Broaden the channels for selecting and employing people, and increase efforts to attract outstanding talents from domestic and foreign industrial enterprises and professional organizations. According to the requirements, complete and optimize the team of teachers and counselors of ideological and political courses in colleges and universities. Explore the employment experience and social practice experience of industrial enterprises as important conditions for hiring professional teachers in vocational colleges. To study and introduce measures for the appointment and management of foreign teachers and standardize the management of foreign teachers.

　　Speed up the reform of post management of college teachers. Actively explore the implementation of the total staff management in colleges and universities. Colleges and universities adopt diversified employment methods according to law to employ people flexibly, make good use of compilation resources, give priority to ensuring the demand of teaching and scientific research, and tilt towards key disciplines, characteristic disciplines and important management positions. Reasonably set the proportion of post structure of teaching staff and strengthen the construction of staff. We will further promote the post employment reform, implement the post tenure system management, further explore the management methods such as the combination of quasi-employment and long-term employment, and implement and improve the employment mechanism that can be promoted and demoted, and can enter and exit.

　　Strengthen the management of teachers’ education and teaching in colleges and universities. Improve the teaching quality evaluation system, multi-dimensional evaluation of teaching norms, teaching operation, classroom teaching effect, teaching reform and research, teaching awards and other teaching achievements. Strengthen the proportion of teaching achievements and the effectiveness of teaching and educating people in performance distribution, job title evaluation and employment, and post promotion assessment, and take a certain amount of undergraduate (specialized) teaching as a necessary condition for the promotion of teachers’ titles. Taking professors as the basic system, colleges and universities should make it clear that professors should undertake the minimum class hours requirements for college students, and those who fail to meet the requirements will be given unqualified annual or employment assessment.

　　Promote the reform of the professional title system of college teachers. Study and introduce the guiding opinions on the reform of the professional title system of college teachers, and delegate the right of professional title evaluation directly to colleges and universities, which will independently evaluate and appoint them according to their posts. Improve the evaluation criteria for teachers’ professional titles, set evaluation indicators according to different disciplines and different post characteristics, and determine evaluation methods. The study experience abroad, the number of patents and the index requirements for indexing, inclusion and citation of papers are not restrictive conditions. Improve the evaluation mechanism of peer experts and carry out the evaluation of representative achievements. Explore the introduction of contribution evaluation mechanism for teachers who undertake national defense and key core technology research tasks. Improve the process of professional title evaluation, and continue to do a good job in the supervision of professional title evaluation of college teachers.

　　Deepen the reform of the evaluation system for college teachers. Highlight quality orientation, pay attention to evaluating teachers according to their ability, performance and contribution, resolutely reverse the tendency of neglecting teaching and educating people, and overcome the disadvantages of focusing on papers, hats, titles, academic qualifications and awards. Standardize the use of indexes related to papers such as SCI in colleges and universities, avoid the absoluteness in the use of citation data such as SCI, SSCI, A&HCI and CSSCI, resolutely abandon "judging papers by journals" and get rid of "SCI first" in papers. Reasonably set the evaluation cycle and explore long-term evaluation. Pay attention to the combination of individual evaluation and team evaluation. Establish a hierarchical feedback mechanism for assessment results. Establish a linkage mechanism of college evaluation, undergraduate teaching evaluation, subject evaluation and teacher evaluation policies, and optimize and adjust the evaluation indicators that restrict and influence the implementation of teacher evaluation policies.

　　Establish and improve the management system of part-time teachers and part-time teachers. On the premise of performing their duties on campus and not affecting their own jobs, college teachers may, with the consent of the school, take part-time jobs that are closely related to their own disciplines and can give full play to their professional abilities. Localities and universities should establish and improve the management system of teachers’ part-time jobs, standardize teachers’ reasonable part-time jobs, and resolutely punish teachers’ part-time chaos. Encourage colleges and universities to hire off-campus experts and scholars as part-time teachers, improve the management measures for part-time teachers, standardize the selection and employment procedures, clarify the standards, responsibilities, rights and work requirements of part-time teachers, and ensure that part-time teachers have high professional ethics, professional ability and educational level.

　　The fifth is to effectively protect the treatment of college teachers and attract stable first-class talents to teach.

　　Promote the reform of salary system in colleges and universities. Implement the income distribution policy oriented to increasing knowledge value, expand the autonomy of salary distribution in colleges and universities, and explore the establishment of a salary system that conforms to the characteristics of colleges and universities. We will explore the establishment of a system for investigating and comparing the salary level in colleges and universities, improve the mechanism for determining and increasing the salary level in colleges and universities, reasonably determine the salary income level of college teachers on the basis of ensuring the normal adjustment of the basic salary level, and increase the inclination to colleges and universities with high-level talents and heavy teaching and scientific research tasks. The cash reward for the transformation of post scientific and technological achievements obtained by college teachers according to law is included in the total performance salary of the unit in that year, but it is not limited by the total amount and is not included in the total base. Implement policies and regulations such as salary and income distribution incentives for high-level talents, part-time and part-time salary, and starting a business after leaving the post. Encourage universities to set up professorships funded by third parties.

　　Improve the incentive mechanism of internal income distribution in colleges and universities. To implement the autonomy of internal distribution in colleges and universities, colleges and universities should improve the internal income distribution mechanism and performance appraisal methods in combination with the actual situation, and tilt towards teachers who are rooted in the front line of teaching and have outstanding achievements, teachers who have undertaken urgent and dangerous tasks and made outstanding contributions, and teachers who are engaged in basic frontier research, national defense science and technology and other fields. Take part in teaching and research activities, write textbook cases, undertake the task of proposition invigilation, and guide students in graduation design, employment, innovation and entrepreneurship, social practice, student associations, competitions and performances, etc. into the workload. Encourage excellent teachers to undertake the teaching work of continuing education, and bring the relevant workload into the performance appraisal system. Do not directly link the quantitative indicators of scientific research such as the number of papers, patents, projects and project funds with performance salary distribution and rewards, and give full play to the incentive-oriented role of income distribution policy.

　　The sixth is to optimize and improve the talent management service system and cultivate a group of high-level innovative talents.

　　Optimize the talent introduction and education system. Strengthen the strategic orientation of serving the country, strengthen the top-level design of the talent system, give full play to the leading role of major national talent projects, strive to build a high-level innovation team, and cultivate a group of scientists, discipline leaders and young academic talents with international influence. Standardize the introduction of talents, strictly control politics and ethics, and achieve "every citation must be judged." Strengthen the construction of talents in philosophy and social sciences and high-end think tanks in colleges and universities, and gather and train a group of famous teachers in philosophy and social sciences. Adhere to the correct orientation of talent flow, encourage colleges and universities to establish industry self-discipline mechanism and talent flow consultation and communication mechanism, and give play to the role of talent work alliance in colleges and universities. Resolutely put an end to the illegal introduction of talents, and those who leave relevant units and posts within the support period without the consent of the competent department of talent planning will be disqualified from the title of talents and corresponding support.

　　Scientific and rational use of talents. Give full play to the role of talent strategic resources, adhere to the correct orientation of talent use, promote the reform of talent evaluation mechanism by classification, promote the return of all kinds of talent "hats" and talent titles to honor and academic essence, avoid repeated support of similar talent plans, select people according to their posts, and determine their salaries according to their posts, and do not take talent titles as restrictive conditions for undertaking scientific research projects, job titles, appraising awards and degree points. Create an academic environment that encourages innovation and tolerates failure, and leave enough exploration time and trial and error space for talents to carry out research. Strict management of talents after employment, strengthen the assessment of contract performance and role play. Strengthen the care and service for talents, and effectively solve their practical difficulties in work and life.

　　Seventh, fully support the growth of young teachers and cultivate a new force in higher education.

　　Strengthen the training support for young teachers. Encourage colleges and universities to expand the number of postdoctoral recruits and take postdoctoral staff as an important source of supplementary teachers. Establish a diversified supplementary mechanism for young teachers to attract overseas students and foreign outstanding young talents. Encourage young teachers to work in enterprises and institutions and visit high-level universities and research institutes at home and abroad.

Purchase tax subsidy blessing, can I buy the minimum XC90？

Easy car original The purchase tax halving policy that just came out of Taiwan a while ago has undoubtedly brought the slightly deserted car market back to its original temperature. Except for some luxury brand models, almost all fuel models have ushered in their "festivals". And for those models whose price or displacement exceeds the standard, it is not just staring at them. Shortly after the policy was introduced, Volvo launched the preferential information of official subsidy of 50% purchase tax for its medium and large SUV XC90, which also further enhanced the preferential range of this car. After all, at present, the end point preferential price of the minimum model B5 Deluxe Edition 5 seats is only 508,900 yuan. All of this is crazy for the price of nearly one million yuan in the early stage of this generation of XC90. But don’t be too happy, let’s see if this lowest XC90 is worth buying.

The exterior is worthy of the identity of Volvo’s flagship SUV

What’s more interesting is that although the price span of the XC90 series has reached 143,000 yuan, it is difficult to distinguish between high and low-end models only from the appearance. Therefore, the low-end models can be said to be a little cheap here. The iconic front of the car must be very familiar to everyone. The waterfall-style front grille and Thor’s hammer LED daytime running lights are all familiar flavors and familiar formulas. And configurations like adaptive far and near light and fog lights can only be owned by top models.

The XC90 is positioned in the medium and large SUV, with a length, width and height of 4953x1958x1776mm and a wheelbase length of 2984mm, which is on the same level as the size and is slightly smaller. However, in this individual-level luxury brand SUV, the price of the XC90 B5 deluxe version of 5 seats is only 508,900 yuan, which is obviously more cost-effective. In addition, the low-end model has no difference in the side design from the high-end version, and is equipped with a 4-door keyless entry function.

The rear of the vehicle has a unique design style of Volvo, and the Viking-style taillights are always the most outstanding part of the rear of the XC90. In addition, there are not many details on the rear of the car, but it highlights the design concept of Volvo, a Nordic brand that pursues simplicity. The exhaust of the vehicle is also concealed. The rear tailgate of the low-end version also has the function of induction electric, and the difference between the entire rear and the high-end version is only reflected in the logo.

Interior configuration pays attention to practical and comfortable

The interior design of the 5-seat XC90 B5 Deluxe Edition still reflects the strength of a large SUV of a luxury brand. Although its dashboard uses a large area of slush molding process, the addition of light-colored wood grain trim still greatly enhances the texture of the interior. At the same time, the leather package added to the door interior version also makes the interior feel luxurious at the appropriate level.

The steering wheel in the car is wrapped in leather, but the whole series is manually adjusted, and the steering wheel heating can only be obtained by the whole series. The B5 Deluxe Edition 5 seats are equipped with a 12.3-inch full LCD meter, and this part of the quality is not lost because of its low-end model status.

The size of the central control screen in the car is 9 inches, which is consistent with the high-end models. It adopts an embedded design to ensure the integrity of the entire center console. The operating interface of the car system is simple and practical, including navigation, basic voice operation, and vehicle to everything functions. Compared with some multi-functional car systems currently on the market, it pursues practicality and convenience. In addition, Apple CarPlay mobile phone interconnection function has also been equipped.

As far as the configuration of the car is concerned, the XC90 B5 Deluxe Edition 5-seat does not have much luxury to speak of. It is equipped with a large panoramic sunroof, which can be seen in many models today. In addition, configurations such as automatic parking, reversing images, keyless start, automatic anti-glare inner rearview mirrors, etc. are some of the more conventional configurations. However, referring to the high-end models of the XC90, except for the rear manual sunshade and the rear independent air conditioner, they are not much different in the car configuration. Configurations such as wireless charging of the front mobile phone, 360 ° panoramic image, and 19-speaker Baohua Weijian audio are only available on the top model. So it seems that the 5-seat configuration of the B5 Deluxe Edition is not too shabby in the entire XC90 car series.

The car seats are wrapped in leather, and the texture is indeed much better than that of ordinary brand models. The front seats each have a total of 10-way electric adjustment function, and are also equipped with seat heating, the main driver’s seat and seat memory configuration. Since the vehicle adopts a 5-seat layout, the second row of seats cannot be adjusted front and rear like the 7-seat model.

The storage space in the car is still very ample, and like some storage compartments in the central passage area, it can be covered by a sliding cover when not in use, preserving the integrity of the design. There are two USB/Type-C ports at the front and rear of the vehicle, and after the second row of seats is reclined, the car can get a very flat space and has a deep longitudinal dimension.

B5 power fully meets daily needs

The whole series is equipped with a 2.0T engine with a 48V light hybrid power system, and the B5 deluxe version has a single supercharged intake mode for 5 seats, so it has a certain weakening in power data compared with the B6 version. However, its maximum power of 184kW and the maximum torque of 350N · m are enough to make the XC90 meet the needs of daily cars. It is matched with an 8AT gearbox. The shift ball head adopts an ordinary design, and only the top model is equipped with a crystal-style ball head. The most intuitive feeling brought by the intervention of the 48V light hybrid system is that the vehicle can only feel very slight vibration when starting and stopping, and the quality is excellent.

The chassis of the vehicle adopts the independent suspension of the front double fork arm type and the rear multi-link type, and the main components of the suspension are made of aluminum alloy. Most XC90 models still use the configuration of coil spring and shock absorber, only the top model uses air spring, and has height and soft and hard adjustment functions.

Although it is the lowest model, but in the driving auxiliary features, XC90 B5 Deluxe Edition 5 seats or should be fully matched, the vehicle is equipped with full speed adaptive cruise, and lane keeping, lane departure warning, active braking and other functions can greatly reduce the driving intensity and improve safety during driving.

editorial reviewAlthough the number of second-child and third-child families is increasing, it is undeniable that the 5-seat model still has its solid market. After all, for most people, a 5-seat SUV is still the best choice. Therefore, as the only 5-seat model configuration of the XC90 series, the competitiveness of the B5 Deluxe Edition 5-seat is not inferior to several other 7-seat configurations. At the same time, its cheaper price makes it more competitive. In addition, users who buy the XC90 from June 1 to June 30, 2022 can enjoy the purchase tax subsidy policy provided by the manufacturer, and the first owner can also have the right to free maintenance for life, which is really exciting.

According to the Easy Car App, Volvo Asia Pacific has sold a total of 114,505 vehicles in the past year, ranking 40th among all joint venture and autonomous car brands.

＂Instant Electronic Music＂ Zhang Yixing asked Feng Timo, and Shang Wenjie’s first gift was impeccable

"Instant Electronic Music"

This Saturday at 8 pm, produced by Tencent Video, Penguin Film and Television and Canxing Productions jointly created China’s first electronic music producer competition show "Instant Electronic Music" will broadcast the second episode. After the first episode of the program aired, topics such as "antifungal agent in the world" and "essential for staying up late to do homework" gradually heated up the public’s enthusiasm for electronic music. In this program, Feng Timo, who has been controversial after the program was exposed, was actually asked by Zhang Yixing at the scene? Not strong enough, "acting like a spoiled child" to get together, and the electronic music girl wearing "laser leather pants" gave Zhang Yixing a headache on the spot! Big Zhang Wei invited the producer to "reverse election" one after another, and the collision between the manager and the producer continued to escalate! More "breakout" highlights are about to be staged in the program.

Frequently encountered group Zhang Yixing fell into "choice difficulties", and Feng Timo’s ethereal interpretation of "Empty City" was questioned

Although Zhang Yixing has become more mature and stable in the music field in recent years with his own continuous efforts, it is obvious that after the professional and shocking surprise appearance of the electronic music producer in the first episode, in the second "Breakout Battle", his choice is increasingly difficult to "give up". In this episode, Zhang Yixing, who frequently encounters the producer combination, focuses on the recommendation standard of "1 + 1 means more possibilities", and therefore falls into "choice difficulties". In the show, Zhang Yixing "encountered" the "girls power" combination wearing leather pants, which made him in a dilemma between "coquetry" and "strength". What happened at the scene?

In addition, another gunpowder-smelling "collision" was Feng Timo, who has caused heated discussions among netizens before. With her sweet and lovely singing style, she is familiar to the public, and her previous music works have also achieved good results on major platforms. Recently, Feng Timo has begun to experiment with electronic music style, and the song "Glass Sugar" once made netizens take a different look at her transformation. However, on the stage of this program, Feng Timo sang "Empty City" ethereal on the spot, but it aroused doubts from many producers present, and they even "forcibly deducted the question". Zhang Yixing, who is not vague about the music, is even more "confused" Feng Timo, and gave a "just passable" evaluation. How will Feng Timo, who is controversial on and off the screen, resolve the embarrassment? All doubts will be solved this Saturday.

"Instant Electronic Music"

Da Zhangwei rarely invites producers to "reverse election", and the follow-up competition system of the show continues to be exposed

After the first episode of Shang Wenjie met Dani’s invitation to cooperate, Da Zhang Wei also directly threw out an "olive branch" in this episode, inviting several producers one after another to "counter-select" himself in the subsequent program. The operation of the two managers also made the follow-up competition system gradually clear. From "selected" to "selected", the roles of the manager and the producer "God’s perspective" were exchanged, and the follow-up points were looking forward to.

At the scene, what kind of performance made Da Zhang Wei couldn’t help but admire: "Truly moving music that can make people forget the’principle ‘" and praise the other party as "Tao Yuanming of the electronic sound"? What kind of wonderful, let him say bluntly, "I didn’t have much expectations, but after watching the performance, it was really a surprise"? The increasingly compact "breakout battle" continued to inspire the enthusiasm of the host. The concept of "feat" that the program has been promoting has gradually emerged through actual presentation, and more unexpected highlights are being staged!

Strict Shang Wenjie’s first gift is "impeccable", hard core "spice combination" electronic sound "soft landing"

In the second episode, the 18-year-old "Salt and Pepper Pineapple" played Launchpad with the light show. Many people were so cool by the young boy, but the host, Shang Wenjie, was completely unmoved.

However, when the "spice combination" that "shook" the stage came on stage, the hard-core European and American voices collided with Fan Xiaoxuan’s sweet and lazy "Your Sweet", and the "soft landing" and powerful performance instantly ignited the quiet and less talkative host Shang Wenjie, who couldn’t help but say "I like it very much, I like it very much"! Shang Wenjie, who has a unique understanding of music, encountered "musical confidant", and she was not hesitant to praise the atmosphere of the show, which made her give a "impeccable" high praise for the first time… The second episode of the show was full of surprises!

Electronic music is a kind of music that allows people to let go of all rules and troubles and immerse themselves in it. The second episode of the program "Ready for Broadcasting" was faced with multi-directional questions. How did Feng Timo respond. Da Zhang Wei invited "counter-selection" one after another on the spot. What kind of performance made him frequently burst "golden sentences"? What kind of wonderful performance made Shang Wenjie, who is strict about music, comment "impeccable"? The enthusiasm of the host and producer for electronic music continues to "heat up", and more exciting, so stay tuned for this Saturday night at 8 o’clock Tencent video "Instant Electronic Music"!

Media survey： Over 80% of netizens support the management of network anchors (Figure)

　　On the 12th, the Ministry of Culture announced the 25th list of illegal Internet cultural activities, and nearly 17,000 network anchors were investigated. The number of illegal network anchors is so huge that it once again reflects the problems in the field of webcasting. From stars to ordinary people, more and more people join the ranks of network anchors. In order to attract more viewers, some network anchors even have no bottom line hype and show off pornography.

　　According to a survey, over 80% of netizens support relevant state departments to guide and manage network anchors. Among them, 48.08% of the respondents think that the live broadcast of eating and sleeping by network anchors is "vulgar and unintelligible". Some public opinion analysts pointed out that network anchors may usher in a big reshuffle in the second half of this year.

　　Some parents worry that their children will be affected.

　　In January of this year, a pair of male and female anchors on the betta platform conducted pornographic live broadcasts, so the vulgarization of network anchors became the focus of public opinion. Weibo, a police officer including Jiangsu Cyber Police, criticized this phenomenon by name and pointed out that two anchors had been suspected of breaking the law.

　　The survival of network anchors depends on the audience’s "reward" in the live broadcast. In order to attract more viewers, network anchors often go sideways, or speculate through verbal and physical cues, or live broadcast of boring behaviors such as eating and sleeping. This kind of soft pornography has brought high popularity and rich income, and network anchors have become more and more "willful".

　　But public opinion has been quite worried about this. By searching for "webcast" through Baidu Index, in terms of crowd division, 12% of followers are teenagers under the age of 19. A parent in Guangzhou once told reporters: "Now students have a mobile phone, and they are really worried that their children will see the bad content of the anchor and have an impact on him."

　　Some time ago, the "Men’s Subway Live Event" in Guangzhou was also criticized by public opinion, not only because the behavior of two men eating and drinking in the subway seriously disturbed public order, but also because their vulgar and "out of place" performance openly publicized a bad social habit. The voice of public opinion for rectifying the webcast platform is also getting higher and higher.

　　The anchor is basically recognized but needs supervision.

　　A few days ago, Questionnaires.com launched a survey about network anchors. The survey results show that over 70% of the respondents have some knowledge of the profession of network anchor, which shows that webcasting has become a phenomenon and is known to most people.

　　However, when asked, "What do you think of the overnight fame of network anchors?", 31.73% of the respondents thought it was a reflection of social impetuous psychology. Some media have reported that the high income of webcasting can reach hundreds of thousands of yuan a month, and the anchor of game commentary can even get an annual salary of 10 million yuan. Under the temptation of interests, many network anchors flock to it.

　　When asked, "What do you think of the influence of network anchor on the public and society?", half of the respondents still recognized the joy brought by anchor. Among them, 14.42% of the respondents think that webcasting broadens their horizons, and even 7.69% of the respondents think that webcasting has established people’s confidence and encouraged the diversified development of humanity and culture. It can be seen that network anchors are basically recognized, but they need supervision.

　　In "Do you think it is necessary for relevant state departments to guide and manage the webcast industry?" In one question, a total of 82.69% of the respondents chose necessary. In addition, 65.38% of the respondents said that network anchors should spread positive energy.

　　The network anchor had high hopes, and his versatility and good sense of camera are all pushing the development of the emerging industry of webcasting. Network anchors have gradually grown into an industry group, and "prohibition" is obviously not the best way.

　　It is true that the cultural department cannot always audit and supervise every network anchor, but it can combine with other relevant departments to introduce corresponding punishment measures to shock the warning. At the same time, the live broadcast platform should fulfill its main responsibility, with sufficient content audit inspectors and strict technical monitoring measures, so as to find, track and identify in time and shut down illegal performances in time. As an anchor, you are also responsible for the live content. In this regard, some experts suggest that real-name registration system measures such as identity authentication should be implemented for network anchors, so that the source can be traced and the responsibility can be investigated.

What should some operators do if they start to reduce the frequency of 2G networks and still use 2G mobile phones？

　　BEIJING, April 18 (Reporter Wu Tao) Recently, it was reported that China Unicom would close its 2G network. China Unicom issued an announcement in response, and is promoting the frequency reduction of 2G networks in an orderly manner. What is frequency reduction in 2G networks? Will it affect consumers and why?

　　Multi-operators start network frequency reduction

　　For the frequency reduction of 2G networks, the reporter consulted the three major operators respectively. China Unicom said,The frequency reduction of 2G network can’t be called closing 2G network, because users are still on 2G network, but there is a process of frequency reduction and slimming step by step..

　　Some insiders who don’t want to be named said that the gradual frequency reduction of 2G is actually the gradual withdrawal of 2G from the network, and the complete disappearance of 2G base stations means that 2G is completely withdrawn from the network; At present, the three major operators are still in a state where 2G, 3G and 4G networks coexist.

　　According to an insider of China Mobile,China Mobile has no plans to quit the network for 2G at present.. As of press time, China Telecom has no reply.

　　However, Fu Liang, an independent telecom analyst, revealed in an interview with Zhongxin.com that in fact, all three major operators are doing network frequency reduction work, and China Unicom is still the latest; Among them, China Mobile is doing 3G network frequency reduction.

　　Will consumers be affected?

　　According to the data released by China Unicom, by the end of February, there were 289 million users in China Unicom, including 187 million 4G users. It is reported that China Unicom’s 2G users account for about 2% of its total users, which means that China Unicom has more than 500 million 2G users.

　　Will these users be affected by the frequency reduction of 2G networks? China Unicom said that it willTake various preferential measures, such as replacing mobile phone cards for free, giving away experience traffic, and offering preferential purchase, to assist existing 2G customers to upgrade to 4G networks.In this process, the existing 2G customer service will not be affected.

　　Xiang Ligang, an expert in communication industry, believes that the frequency reduction of the 2G network of China Unicom is not affected by the vast majority of consumers.

　　Fu Liang believes that it is impossible for 2G users to have no impact at all. It can only be said that it is less affected. After frequency reduction, 2G network coverage may be insufficient in some places, "butFrequency reduction does not mean that the 2G network cannot be used, because there are still 2G base stations.. "

　　The reporter noted that, despite the current 4G era, 2G or 3G networks still play a role. Some users said in an interview with Zhongxin.com, "I still feel that the existence of 2G networks is better becauseIn some places, there is no 4G network coverage. When passing through these places, the mobile phone will automatically switch to 3G or 2G networks, and there is still a process of connecting when using it, or it will be disconnected."

　　Data Map: There are more and more 4G users. The picture shows Shenyang citizens using the 4G network to surf the Internet for free on the bus. China News Agency issued by Haiyang Photo

　　Why do you want network frequency reduction?

　　Since there are still users, why do you want to reduce the frequency of 2G networks?

　　Fu Liang said that it turned out that2G network occupies some frequency bands, and some frequency bands are scarce, which can be said to be valuable resources. After reuse, it can be used in 4G network construction., which is conducive to improving network quality and network wide-area coverage.

　　China Unicom also indicated that the bandwidth resources will be used for higher 4G networks and deployment.

　　"In addition, with the decrease of 2G and 3G users, its network capacity is more and more surplus, and its base station and other facilities are increasingly uneconomical to invest in operation and maintenance, which is another reason." Fu Liang said.

　　This is true. According to the latest data from the Ministry of Industry and Information Technology, as of the end of February, the number of mobile phone users of the three major operators reached 1.44 billion, of which the total number of 4G users reached 1.03 billion, and 4G users accounted for 71.6% of mobile phone users.

　　However, the data of the Ministry of Industry and Information Technology also showed that as of the end of February,The total number of mobile broadband users (namely 3G and 4G users) reached 1.17 billion. This means that there are still 270 million 2G users, which is still a huge number..

　　In view of this, Fu Liang believes that it is impossible for the three major operators to shut down the 2G network at once. Network frequency reduction is a gradual process, and 2G users do not have to worry too much.

　　"It should also be pointed out that if the equipment used by 2G users supports WCDMA, even if China Unicom shuts down the 2G network, it will still have no impact on them." Fu Liang said. (End)
