Teacher recruitment examination questions leaked? The discipline inspection and supervision department has been involved in the investigation!

  Cctv newsOn June 23rd, a contract teacher recruitment examination was held in Dongxihu District, Wuhan City, Hubei Province, with more than 3,000 participants. However, after the examination, some candidates reported that the examination questions were similar to a forecast paper on the market in a large area. What happened?

 

  On June 28th, the reporter found the Education Bureau of Dongxihu District, Wuhan City, which organized the recruitment examination on the same test paper.

  Li Xingtong, Deputy Director of Education Bureau of Dongxihu District, WuhanThis is the test paper of our written test, and this is the so-called sprint prediction test in a training institution. You see, the first question of our written test is exactly the same as the first question in it (the prediction paper), from the first question to the later part of this to the 40 questions, and the whole order is made according to this.

  According to the examinee’s reflection, the score of 100-point test questions and similar test questions will reach 60 points.

  candidate for an entrance examinationEveryone is saying that there are 40 questions on that topic that are exactly the same as the forecast paper of an institution, and the ABCD order of the questions and even the answers has not changed.

  Invalid test results, re-test the organization

  On June 26th, the government of Dongxihu District issued a notice on its official website, announcing that the exam results on June 23rd were invalid, and will organize a retake on July 7th.

  Li Xingtong, Deputy Director of Education Bureau of Dongxihu District, WuhanFor those candidates who don’t want to take the second exam, we will refund all their registration fees. For those candidates who are not from Wuhan, we will reimburse 200 yuan for the first day or the same day’s accommodation. For those candidates who need to take transportation, we will actually reimburse their transportation expenses.

  It is understood that in the first recruitment examination, the Dongxihu District Education Bureau was entrusted by Party A to a third party, that is, the state-owned enterprise under the Wuhan Human Resources and Social Security Bureau to organize relevant recruitment work, including questions. There is such a large area of similarity. What is the problem?

  Li Xingtong, Deputy Director of Education Bureau of Dongxihu District, WuhanAlthough we entrusted a third party to carry out this examination in strict accordance with the relevant procedures, our education department is the administrative department after all. We are not considerate in our work and lack of supervision. I once again express my deep apologies to our candidates.

Zhang lei, head of Zhiyong Accountability Office in Dongxihu District, Wuhan.

  Zhang lei, Head of the Accountability Office of Dongxihu District, Wuhan:We have combined the preliminary evidence and locked the relevant responsible departments. In the next step, we will intensify the investigation. Once we find any violation of discipline and discipline, we will seriously pursue the responsibility and accountability, and will never tolerate it.

  In view of the re-examination, relevant departments have made corresponding rectification measures.

  Liu Xiangdong, Deputy Inspector of Wuhan Ministry of Human Resources and Social SecurityEspecially in the process of making questions and propositions, we should come up with corresponding systems to prevent such phenomena from happening again in the future.

  It is understood that the local discipline inspection and supervision department has been involved in the investigation and initiated the corresponding accountability procedures. We will also continue to pay attention.

Blizzard continues! Snowfall in the north stopped for 5 days, and rain and snow in the south continued until New Year’s Eve.

This round of freezing rain and snow is experiencing the strongest period. In the past 24 hours, Jianghuai area has become the core area of heavy snowfall in this process, with heavy snowstorms in central and eastern Hubei, southern Anhui and central and northern Jiangsu, and heavy snowstorms in some areas.

This round of freezing rain and snow is going through the strongest period. In the past 24 hours, the Jianghuai area has become the core area of heavy snowfall in this process. Heavy snowstorms have generally appeared in central and eastern Hubei, southern Anhui and central and northern Jiangsu, and heavy snowstorms have occurred in some areas.

The snow along the middle and lower reaches of the Yangtze River is "black" …

This rain and snow process is not only strong, but also extremely complicated mixed precipitation. Rain, snow, ice particles, freezing rain, thunder … all of them! For example, in Yichang, Hubei Province, rain was observed at 23: 00 on the 2 nd, and it turned to snow at around 4: 00 on the 3 rd. At the same time, thunder and snow were also detected.

In addition, the snowfall in Hefei, Anhui Province from 08: 00 to 14: 00 today was 8.5 mm, which almost caught up with the magnitude of the 24-hour standard blizzard (10 mm). There was also freezing rain, and the power line accumulated ice of 28 mm.

Due to the low temperature, the efficiency of snow accumulation in Anhui, Henan and other places is high, and the accumulated snow in many places has exceeded 10 cm. According to the actual situation of snow this afternoon, the depth of snow in Guoyang, Lixin, Yingshang, Bengbu, Funan, Jieshou, Fuyang, Wuhe and Mingguang in northern Anhui is 13 cm, 13 cm, 12 cm, 12 cm, 11 cm, 11 cm, and the snow is enough to have no ankles.

There will be heavy snowfall in Hubei, Anhui and other places from tonight to noon tomorrow. It is estimated that from 20: 00 on February 3 to 20: 00 on February 4, there will be heavy blizzards in parts of southern Henan, most of Hubei, central and northern Anhui, western Jiangsu, northern Hunan, eastern Chongqing and northeastern Guizhou, among which there will be heavy blizzards (20-24 mm) in parts of northeastern Hubei and central Anhui. The depth of newly added snow in the above areas is 3 ~ 10 cm, and the local area can reach about 20 cm.

From night to tomorrow, there will be freezing rain in parts of central Anhui, southern and eastern Hubei, most of Hunan, central and eastern Guizhou and southeastern Chongqing. The accumulated freezing rainfall can reach 1 ~ 6 mm, and the local area is about 10 mm.

In terms of specific cities, the snowfall from Wuhan to Hefei will continue to increase in the early morning of tomorrow, and there will still be blizzards and local blizzards; It will also be snowing heavily in Nanjing tomorrow. In addition, Jingmen, Jingzhou, Yichang and other places in Hubei will have heavy snow tonight; There will be freezing rain at Yueyang and Xiangtan stations in Hunan.

In the next two days, Guizhou, Hunan, Hubei and Anhui will become the areas with the most concentrated freezing rain and heavy snowfall. Among them, there may be both freezing rain and snowfall in the northwest of Hunan, eastern Hubei and central Anhui, which has a great impact.

Affected by rain and snow, most of the traffic in the central and eastern regions will be affected, such as Shanghai-Chongqing, Shanghai-Shaanxi, Fuyin, Beijing-Hong Kong-Macao and other expressways, which will have a long section affected by blizzard and freezing rain. It is best for returnees to avoid the period with the strongest rain and snow, pay attention to the latest road traffic information, plan their trips reasonably and drive safely.

After the 5th, the snowfall in the northern region will shrink sharply and basically end on the 6th. However, due to the active warm and humid air flow in the south, a large range of rain and snow weather in the south will last until New Year’s Eve.

It is estimated that until the 8th, there will be a large range of moderate to heavy rain and local heavy rain in the south of the Yangtze River and northern South China, and the accumulated rainfall is large. The accumulated rainfall in Hunan, Jiangxi and Guangdong can reach more than 100mm, which is much higher. Especially in Hunan and Guizhou, there will still be mixed rain and snow.

The continuous large-scale rain and snow will also cause a "heavy blow" to the temperature in the central and eastern regions. Especially in Anhui, Hunan, Henan, Jiangsu, Hubei and other places with a wide range of rain and snow and lasting time, the highest temperature in many places will be more than 6 C lower than normal, and the local temperature will be about 10 C! In the next four or five days, the highest temperature in many cities, including Zhengzhou, Hefei, Wuhan, Nanjing and Changsha, is only about 0℃. With the rainy and snowy weather, the body will feel very wet and cold.

It is expected that before the Spring Festival, most areas in the south will continue to be in a state of low temperature and wet cold, and it is necessary to wait for the New Year to get warmer.

How did the whistle and brilliant colors of fireworks come about?

When Xiao Bian was very young, he liked to run to the balcony to watch fireworks every New Year. After a bang, a bright and colorful fireworks burst into the distant sky, gorgeous and beautiful.
All kinds of fireworks @Wikipedia
Therefore, Xiao Bian, who was young and ignorant at that time, couldn’t help wondering … Why did a small box on the ground look like that after being ignited? How on earth are fireworks designed and made in order to show such a brilliant effect?
The picture comes from the Internet.
There are many kinds of fireworks, and the fireworks seen in general TV programs, that is, the kind that flies to the sky with a bang and then explodes, are a special kind of fireworks called fireworks.
Fireworks @Wikipedia
Fireworks bloom can be roughly divided into two stages. The first stage is the launch of the fireworks bomb: with a bang, something on the ground flew into the sky. The second stage is probably the burst of fireworks, and a firework exploded in the sky. What happened in these two stages respectively?
The internal structure of a certain kind of fireworks is probably like this [1].
Fireworks structure @pyrouniverse.com
Hit the fireworks into the sky
When we lit the fuse (fast fuse), the fuse gave the friends time to evacuate and delayed the explosion. When the fuse burns to the propellant, ignite the propellant. Propellant is generally black powder discovered by the ancient alchemist in China. After the fireworks are lit, the sound of "bang" is the explosion of this thing. The main components of black powder are sulfur, charcoal and potassium nitrate, and the reaction formula of explosion is complicated. A typical chemical reaction equation looks like this (familiar with one sulfur, two nitrates and three carbons):
This explosion reaction produces a lot of heat and high-temperature gas, which is similar to the principle of rocket launch. The high-temperature gas produces huge thrust and pushes the shell into the sky. In the process of flying high into the air, we often hear the whistling sound, which is a sound effect of fireworks. It comes from a special thermal-acoustic coupling combustion-pulsating combustion.
Pulsating combustion
Pulsating combustion is a special unstable combustion process, and the parameters such as temperature, pressure and airflow speed in the combustion zone will fluctuate periodically with time. In the process of industrial application of pulsating combustion, there will be a lot of noise radiated from the tail pipe of the burner [2]. This technology involves many nonlinear processes of thermo-acoustic coupling, large amplitude acoustic wave effect and so on, which is very complicated, so there is no relevant theory at present [3].
But the fact that there is no relevant theory doesn’t mean that we are not here or can’t use it.
People engaged in fireworks production already know that in order to make fireworks produce this whistling sound, it is necessary to use a special kind of combustion product-flute agent. Oxidizers (potassium perchlorate and potassium chlorate) and flute agents (mainly derivatives of benzene) are mixed and packed into paper or plastic tubes, and pulsating combustion will occur after ignition, resulting in crisp flute sound [4].
@ References [4]
This pulsating combustion causes thousands of violent vibrations of air every second, releasing high-frequency sound waves. Therefore, the combustion chamber loaded with flute agent and oxidant acts as a propeller, and at the same time, it also emits a sharp whistle-like sound.
In addition to the fireworks launched, there is also a famous fireworks with sound. Xiaobian’s hometown likes to call him a monkey, which is this thing:
@bilibili-av8389766
The ingredients of the propellant used in this kind of thing are potassium perchlorate and potassium hydrogen phthalate. And this potassium hydrogen phthalate, as can be seen from the above table, is also a flute agent (although the sound frequency emitted by combustion is unstable, it still produces a sound pressure of 100dB).
Burst out a firework.
After the propellant is detonated, the delay lead is ignited and the time is started. By the time the shell flies to high altitude and needs to be ignited, the delay lead is almost burned out. So the explosive was detonated and the stars were blown all over the sky. The figure of the fireworks explosion depends on the position of the stars in the shell. If the medicine makes the fireworks explode into a specific shape, it is necessary to design the arrangement of the stars in the fireworks subtly [5].
What the hell is this star? It is the most crucial and mysterious part of the whole fireworks display ~
Its main components are magnesium powder, potassium perchlorate and metal salt or metal powder [6].
Star Composition @ Paperclip-How to Make Explosive Fireworks
After the star is ignited, magnesium powder as reducing agent and potassium perchlorate as oxidizing agent burn violently, giving off a lot of light and heat (but not gas) and becoming the shining things in the fireworks.
But how did the colors of fireworks come from? This involves an important phenomenon related to physics and chemistry-flame reaction.
flame reaction
Simple metals or their compounds will evaporate into individual particles at extremely high temperature, and only individual particles can exhibit flame reaction. (There is no flame reaction in bulk solid samples, because the luminescence of bulk materials is mainly related to the movement of electrons in the materials, and there are various electrons in different movement states in bulk solid samples, so the spectrum of light emitted by bulk materials is very wide and does not present a relatively single color [7]). However, the free metal simple substance or metal ion in the flame will be excited to an excited state with higher energy at high temperature.
However, the excited atom at higher energy is unstable, and it will always transition to the most stable ground state with the lowest energy. In this process, the photon energy (hν) emitted by the atom is exactly equal to the energy difference between the excited state (energy E2) and the ground state (energy E1).
@Wikipedia
The wavelength of photons emitted in this way does not depend on the temperature of the evaporated metal particles, but only on the energy difference between the two energy levels where the transition occurs, and this energy difference is only related to the kind of atoms.
Therefore, different metal ions will have different colors. In this way, we can use various metals and metal compounds to produce various colors.
The metals or metal compounds in the stars, heated by the huge heat released by the burning of magnesium and potassium perchlorate, emit their own light through the flame reaction.
The color of flame reaction [8]
tag
It’s been more than a dozen Spring Festival from a silly child who knows nothing to today’s Xiaobian. Looking at the manuscript, I can’t help but think of myself skipping in front of fireworks more than ten years ago. Time flies, the sun and the moon fly. Although it is more and more difficult to see the fireworks bloom, their physical and chemical principles are becoming more and more clear.
Anyway, it’s the Spring Festival. While enjoying the beautiful and gorgeous fireworks, don’t miss the same beautiful and gorgeous physical and chemical principles behind the fireworks ~
Ps: Places where fireworks and firecrackers are prohibited should strictly abide by the regulations.

Overseas investors increase the allocation of China stock market-international institutions cast a "vote of confidence" in China market.

  Recently, a number of international investment institutions, including Morgan Stanley and Goldman Sachs, have been "singing more" on the China stock market, and many institutions have even taken out "real money and silver" to buy more China assets.

  Experts said that with the implementation of a series of steady growth measures in China and the accelerated optimization of epidemic prevention and control measures, the expectation of China’s economic stabilization and rebound has become clearer, attracting international institutions to re-examine the allocation value of China’s assets. In the future, under the background of China’s deepening the high-level institutional opening-up of the capital market, the efforts of international institutions to "buy in buy buy" are worth looking forward to.

  Institutional upward adjustment expectations

  Recently, a number of overseas investment institutions have increased their allocation to the China stock market.

  On December 4th, Morgan Stanley upgraded the China stock market from "standard" to "over-allocation", and it is predicted that the MSCI China Index will rise by 14% by the end of 2023. Wang Ying, chief equity strategist of Morgan Stanley China, said that the evaluation framework shows that the prevention and control measures of China epidemic are continuously optimized, the real estate market is stabilized, and the regulatory adjustment is in the final stage, so the stock risk premium may be improved, so the target price for the entire China market is raised, and there is a greater chance of revaluation by 2023.

  Coincidentally, on November 30, Goldman Sachs also said that it would also give a proposal of "high allocation" for A-share investment in 2023, and it is expected that the valuation of A-shares will rebound significantly. Liu Jinjin, chief China equity strategist of Goldman Sachs, said that under the expectation that the macro-control is intensified and the GDP growth rate is expected to pick up, we are optimistic about the performance of China stocks listed at home and abroad.

  Bank of America’s strategy team believes that China’s domestic stocks are bound to rise due to the excess savings of China residents and the continuous optimization of epidemic prevention policies. Rui Dalio, the founder of Bridgewater, believes that some valuable assets can be found in the China market at present. China is the second largest economy in the world, and investors can improve their diversification by investing in China.

  The support of international institutions is not groundless. Recently, the overseas listed China ETF, China Stock Exchange and offshore RMB exchange rate all ushered in a wave of solid rise, which enhanced the confidence of foreign institutions to invest in China. For example, since November, the net value of iShares MSCI China ETF with a scale of over $7 billion has increased by over 30%; NASDAQ Jinlong China Index rose by more than 40% in November, the largest monthly increase since records began in 2003. The RMB exchange rate has also recently gone out of a strong upward trend. On the morning of December 5, the offshore RMB exchange rate against the US dollar rose to 6.9813, the highest since mid-September.

  "At present, some major economies continue to tighten monetary policy, the risk of economic recession has intensified, and market return expectations have weakened. In contrast, China has a stable economic development and clear investment logic. " Li Zhan, chief economist of China Merchants Fund Research Department, analyzed that China’s economy is changing from high-speed growth to high-quality development, and there are a lot of investment opportunities in the process of industrial upgrading and consumption upgrading in various industries. At the same time, China recovered quickly from the impact of the epidemic, and its economy rebounded significantly in the third quarter, and its position in the global industrial chain was rising day by day. In addition, China’s financial opening to the outside world has been continuously promoted, and the channels for foreign investors to participate in the domestic financial market have been continuously optimized, attracting the attention of more and more international investors.

  The attractiveness of A shares has increased.

  In addition to high-profile "singing more" China assets, foreign investors also took out "real money and silver" and continued to substantially increase their positions in A shares. As of December 6, the net purchase of northbound funds in 30 days exceeded 75 billion yuan, and the net purchase in the past 10 days reached 42.8 billion yuan.

  Looking forward to 2023, the market expects that the pace of foreign investment "buying in buy buy" will continue to accelerate. "In 2022, nearly 70% of the financing amount in the A-share market comes from science and technology innovation board and the Growth Enterprise Market, which fully reflects the support of the capital market for technological innovation enterprises and emerging industries." Sun Jin, a partner of PricewaterhouseCoopers China Comprehensive Business Services Department, said that in 2023, with the steady progress of the comprehensive registration system reform and the introduction of more measures to support scientific and technological innovation, the international attractiveness of the A-share market will be further enhanced.

  As for the investment industry, the strategy team of Goldman Sachs believes that with the implementation of policies and measures to stabilize growth and the continuous optimization of epidemic prevention and control measures, the unemployment rate in China will drop, labor income will improve, consumer confidence will be restored, and consumer services, medical equipment and service sectors will rebound strongly, especially in tourism, catering, entertainment and aviation industries.

  "Next, the geopolitical situation will enter a relatively calm stage, and the equity cost and equity risk premium will gradually decline, which will help investors reinvest in the China stock market. The consumer sector is the beneficiary of economic opening up. We further increase our exposure to this sector and continue to suggest increasing the allocation of offshore China stocks. " Wang Ying said.

  In order to better attract foreign investment into the China market, Tian Lihui, president of the Institute of Financial Development of Nankai University, believes that it is necessary to persist in promoting the high-level institutional opening-up of the capital market and make overall plans for development and security. It is necessary to continue to expand the interconnection quota, continuously increase the variety of international products, gradually liberalize the restrictions on foreign-funded shares of financial institutions, and continue to promote the internationalization of the RMB. At the same time, the capital market should be opened to the outside world with gates, there should be room for trading rules, and market supervision should be real-time and prudent to prevent foreign hot money speculation and prevent the spread of foreign financial risks.

  Fang Xinghai, vice chairman of China Securities Regulatory Commission, also said recently that high-quality overseas capital market institutions are welcome to invest and exhibit in China. In the future, we will further improve the institutional framework for opening up the capital market, accelerate the implementation of various opening-up measures, and attract and gather more outstanding international institutions and talents to participate in China’s capital market. We will continue to improve relevant institutional arrangements, further facilitate cross-border investment by domestic and foreign investors, and better support cross-border financing development of enterprises.

  Competing for exhibition industry in China

  Since the beginning of this year, the policy dividends to further improve the convenience of foreign investment in China’s assets have been released intensively, giving foreign institutions a "reassurance" to enter the China market.

  On April 26th, the CSRC issued the Opinions on Accelerating the High-quality Development of Public Offering of Fund Industry, proposing to support high-quality overseas financial institutions with long-term investment will to set up fund management companies or expand the shareholding ratio. On November 18th, the People’s Bank of China and the foreign exchange bureau jointly issued the Regulations on Fund Management of Foreign Institutional Investors’ Investment in China Bond Market, which improved and clarified the requirements for fund management of foreign institutional investors’ investment in China Bond Market.

  The convenience of foreign-funded institutions’ exhibition industry in China has been continuously improved, and the business scope and regulatory requirements have achieved national treatment. At present, more than 10 foreign-controlled or wholly-owned securities fund futures companies, such as JPMorgan Chase, Goldman Sachs, Nomura and UBS, have been successively approved, and foreign banks such as Standard Chartered Bank have obtained fund custody qualifications in subsidiaries in China. Foreign private equity funds such as Qiaoshui and BlackRock have successively set up 38 wholly-owned subsidiaries.

  On November 25th, Lubomai Fund announced that it had obtained the Public Offering of Fund business license issued by China Securities Regulatory Commission, becoming the second wholly foreign-owned fund management company newly established in China to conduct Public Offering of Fund business. Lubomai Fund said that the continuous opening of the financial market and the increasingly perfect business environment ruled by law have further enhanced Lubomai’s confidence and hope to further integrate into the development of China’s capital market in the future.

  A number of foreign-funded institutions have started to exhibit in China. At the end of October, ICBC Wealth Management of Goldman Sachs, which was approved to open in June this year, launched the first wealth management product "Shengxin Junzhi Private Bank Enjoy Quantitative Equity Wealth Management Product Phase 1", with a maximum fundraising scale of 5 billion copies. Goldman Sachs ICBC Wealth Management previously said that after the deep correction in the previous period, the value of A shares is becoming prominent, and there is a large room for long-term holding.

  As the first wholly foreign-owned public offering, BlackRock Fund has issued three equity funds and one "fixed income+"fund since it was approved in June 2021, and its products are diversified. Lu Wenjie, investment director of BlackRock Fund, said that A-shares are a market with great breadth and depth, wide investment scope, many related target companies and good liquidity. With the continuous strengthening of China’s opening to the outside world, it is believed that the integration of the global market and the China market will be a long-term trend.

  "More outstanding international institutions entering the A-share market are investing in China’s economic growth prospects and the profitability of China enterprises ‘ A vote of confidence ’ Being able to form a healthy competitive interaction with domestic institutions is conducive to expanding the breadth and depth of China’s capital market, and is also conducive to the continuous improvement of service capabilities of related industries and helping China’s economic development. " Tian Lihui said.

Foreign media commented on 10 games that have been played for more than 100 hours recently, such as Bode Gate 3.

Some games have something special that allows players to play for more than hundreds of hours. Players will take the time to check every corner and complete every task. Although there are very few games with this experience, there have been some such games in the game market in the past few years. Foreign media counted 10 games worth playing for 100 hours for players today.
