2 . The Rise of Voice Technology

Voice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.

Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.

Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.

To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases where the software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.

To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.

Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.

4 . Recently I attended several meetings where we talked about ways to attract students and keep younger faculty members from going elsewhere. It seems higher education has become an industry of meeting-holders whose task is to “solve” problems — real or imagined. And in my position as a professor at three different colleges, the actual problems in educating our young people and older students have deepened, while the number of people hired — not to teach but to hold meetings — has increased significantly. Every new problem creates a new job for an administrative fixer. Take our Center for Teaching Excellence. Contrary to its title, the center is a clearing house (信息交流中心) for using technology in classrooms and in online courses. It's an administrative sham (欺诈) of the kind that has multiplied over the last 30 years.

I offer a simple proposal in response: Many of our problems — class attendance, educational success, student happiness and well-being — might be improved by cutting down the bureaucratic (官僚的) mechanisms and meetings and hiring an army of good teachers instead.

If we replaced half of our administrative staff with classroom teachers, we might actually get a majority of our classes back to 20 or fewer students per teacher. This would be an environment in which teachers and students actually knew each other. The teachers must be free to teach in their own way — the curriculum should be flexible enough so that they can use their individual talents to achieve the goals of the course.

Additionally, they should be allowed to teach, and be rewarded for doing it well. Teachers are not people who are great at and consumed by research and happen to appear in a classroom. Good teaching and research are not exclusive, but they are also not automatic companions. Teaching is an art and a craft, talent and practice; it is not something that just anyone can be good at. It is utterly confusing to me that people do not recognize this, despite the fact that pretty much anyone who has been a student can tell the difference between their best and worst teachers.

5 . Procrastinators (拖延症患者)，take note: If you’ve tried building self-control and you’re still putting things off, maybe you need to try something different. One new approach: Check your mood.

Often, procrastinators attempt to avoid the anxiety or worry aroused by a tough task with activities aimed at repairing their mood, such as checking Facebook or taking a nap. But the pattern, which researchers call “giving in to feel good,” makes procrastinators feel worse later, when they face the consequences of missing a deadline or making a last-minute effort, says Timothy Pychyl, an associate professor of psychology at Carleton University.

Increasingly, psychologists and time-management consultants are focusing on a new strategy: helping procrastinators see how attempts at mood repair are destroying their efforts and learn to control their emotions in more productive ways.

The new approach is based on several studies in the past two years showing that negative emotions can damage attempts at self-control. It fills a gap among established time-management methods, which stress behavioral changes such as adopting a new organizing system or doing exercises to build willpower.

Researchers have come up with a playbook of strategies to help procrastinators turn mood repair to their advantage. Some are tried-and-true classics: Dr. Pychyl advises procrastinators to just get started, and make the doorstep for getting started quite low. “Procrastinators are more likely to put the technique to use when they understand how mood repair works,” says Dr. Pychyl, author of a 2013 book, “Solving the Procrastination Puzzle.” He adds,“A real motive power comes from doing what we intend to do—the things that are important to us.”

He also advises procrastinators to practice “time travel”—projecting themselves into the future to imagine the good feelings they will have after finishing a task, or the bad ones they will have if they don^’t. This cures procrastinators’ tendency to get so stuck in present anxieties and worries that they fail to think about the future.

Another mood-repair strategy, self-forgiveness, is aimed at dismissing the self-blame. University freshmen who forgave themselves for procrastinating on studying for the first exam in a course procrastinated less on the next exam, according to a recent study led by Michael Wohl, an associate professor of psychology at Carleton.

Thomas Flint learned about the technique by reading research on self-control, including studies by Dr. Sirois and Dr. Pychyl. He put it to use after his family moved recently to a new house. Instead of beating himself up for failing to unpack all the boxes gathered in his garage right away, Mr. Flint decided to forgive himself and start with a single step. I’d say, "OK, I’m going to take an hour, with a goal of getting the TV set up, and that's it, he says; then he watched a TV show as a reward. Allowing himself to do the task in stages, he says, is “a victory.”

6 . Japanese officials say they are pleased with the quality of the asteroid (小行星) material collected by a spacecraft and returned to Earth.

Last week, officials from Japan described the samples (样品), which were collected from the Ryugu asteroid in July 2019. Ryugu sits more than 300 million kilometers from Earth. Japan’s unpiloted Hayabusa2 spacecraft removed the material after making a hole into the asteroid.

The space agency said the July 2019 mission (任务) aimed to collect samples from below the surface of Ryugu. During an earlier operation in February 2019, Hayabusa2 collected material from a different part of the asteroid. The second collection effort resulted in sample pieces as big as 1 centimeter. The black material looked similar to charcoal and was very hard. It did not break apart when picked up or poured into another container.

Earlier this month, space officials described the samples Hayabusa2 removed on its first mission as smaller, sandy pieces. They were collected from the surface of Ryugu. Hayabusa2 was launched in December 2014 and arived near Ryugu in June 2018. The Japanese space mission aims to use the samples to learn more about how our solar system formed.

To get the second set of samples in July, Hayabusa2 used an impactor to knock the asteroid’s surface. The aim was to collect material unaffected by space radiation or other environmental conditions. The size differences suggest different hardness of the bedrock of the asteroid. One possibility is that the place of the second touchdown was a hard bedrock and larger particles broke and entered the container.

Hayabusa2 is now on another mission to a smaller asteroid, called 1998KY26. The Japanese government expects the aircraft to take 11 years to reach that asteroid. Hayabusa2’s new mission aims to study possible ways to prevent large meteorites (陨石) from hitting Earth.

7 . In recent years, the Yi Jin Jing exercise has gained great popularity among Chinese of all ages, thanks to Jin Yong’s novels and the Shaolin Temple in Central China’s Henan province, which has promoted kung fu techniques, including Yi Jin Jing, vigorously(蓬勃地) at home and abroad. There are more than 60 types of Yi Jin Jing exercises spreading in contemporary China, differing in lengths, gestures and movements. Thousands of health and fitness clubs in the country have been teaching classical techniques, Yi Jin Jing being the most favored course.

In ancient times, average people did the Yi Jin Jing exercise for health and longevity(长寿) , But kung fu masters do it in different and more difficult ways, hoping to hugely improve their physical abilities. For example,when it comes to breathing, a normal person, especially a beginner, would be advised to take a safe and comfortable approach. But kung fu masters would use an opposite deep breathing technique when doing Yi Jin Jing. They would breathe in deeply, then hold their breath while trying to lengthen certain muscles and tendons(筋), and in the end they would relax and breathe out very slowly.

It is widely believed that Zong Heng, a monk in Ming Dynasty, invented the Yi Jin Jing qigong exercise while he lived in a cave on Mt. Zining, where Zhangjiajing village is located.

In 2016,the Tiantai county people’s government in East China’s Zhejiang province officially declared Pingqiao, a mountainous town, as “Yi Jin Jing Township”, with Zhangjiajing village at its center. At least 30,000 local residents in and around the “Yi Jin Jing Township” have learned to perform the so-called Zining YiJin Jing qigong exercise. They put on massive performances for tourists. Yi Jin Jing training courses, coupled with hillside camping, sightseeing, local foods, have brought great benefit to the previously poor county.
