2 . Teachers worried about students turning in essays written by a popular artificial intelligence chatbot now have a new tool of their own.

Edward Tian, a computer science major at Princeton University, has built an App called GPTZero to detect whether a text is written by Chat GPT, which is a popular chatbot that has caused fears over its possibility for immoral uses in American academic circles. His motivation to create the computer program was to fight what he sees as an increase in AI plagiarism (剽窃). Since the release of ChatGPT in 2022, there have been reports of students using the language model to pass off AI-written assignments as their own. Many teachers have reached out to him after he released GPTZero, telling him about the positive results they’ve seen from testing it.

To determine whether an essay is written by a computer program, GPTZero uses two indicators: “confusion” and “burstiness (突发性)”. The first indicator measures the complexity of text; if GPTZero is confused by the text, then it has a high complexity and it’s more likely to be human-written. However, if the text is more familiar to GPTZero — because it’s been trained on such data — then it will have low complexity and therefore is more likely to be AI-generated. Besides, the second indicator compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or complex sentences alongside shorter ones. AI sentences tend to be more uniform.

In a demonstration video, Tian compared the App’s analysis of a story in The New Yorker and a Linked In post written by ChatGPT. It successfully distinguished writing between human and AI. However, GPTZero isn’t foolproof, as some users have reported when putting it to the test. He said he’s still working to improve the model’s accuracy.

Tian is not opposed to the use of AI tools like ChatGPT. GPTZero is “not meant to be a tool to stop these technologies from being used,” he said. “But with any new technologies, we need to be able to adopt it responsibly and we need to have protections.”

4 . Would you take a trip if you couldn’t use your cellphone? A new tour company called Off the Grid is asking travellers to put their cellphones away and not even use them for photos. The company founder, Zach Beattie, is developing his business, using money he saved from a tech job at a mapping company. He’s hired guides for every trip but will help lead the first few himself.

The first trip is to Lisbon, Portugal, in July. It takes 7 to 10 days, with small groups of up to 16 people. Prices range from $1,500 to $1,650, including accommodations, meals and ground transportation. The plan includes at least three excursions (远足) and two social events, with an emphasis on unique experiences over bucket-list sightseeing. The tour also includes surfing lessons, yoga on the beach, a day of sailing and dinner with a local family.

“When you’re somewhere new, there’s a lot to see and a lot of cool and interesting people to meet,” Beattie said. “Your phone can distract (使分心) you.” The phone ban won’t be enforced quite as strictly as it seems at first glance. “We want it to be voluntary,” he said. “We’re not collecting phones and throwing them in a locked trunk. It’s held by you, but put in your pocket, and you state your intentions for the week, whether that’s checking your social media once or twice a day or a total blackout.”

Tour-goers also get a “dumbphone” without Internet access that’s loaded with numbers for group leaders and other participants, both for emergencies and to promote socializing. Participants may bring regular cameras, but Beattie is hiring a photographer for each tour so there will be plenty of photos to remember the trip. Once the trip is over, participants will have access to those photos for use in social media posts.

5 . Grace Hemingway gifted her son, Earnest, a copy of Henry Wadsworth Longfellow’s epic poem Hiawatha on his sixth birthday. While it’s hard to say how much her choice of gift influenced Earnest Hemingway at the time, he grew up to become one of the most famous writers in history.

Books can make for charming gifts. Giving a book as a gift to someone is much more than a simple exchange of goods.

When giving books, think about your recipients’ (接受者) favorite. It is worth the time to try and find a rare copy, like first editions or signed copies. They’ll be delighted by the effort. Are your friends stuck in a dullness and in need of some motivation? You can gift them a book that offers inspiration. Also, not mainstream yet useful guides related to their career are helpful.

A book when received as a gift has meaning to the recipient by itself if you’ve put some thought into it. An inscription (题词) adds to the appeal of your gift by making it more individualized. Without an inscription, although still meaningful, the book is just a book indistinguishable from hundreds of thousands of copies out there. A case for not penning down an inscription is that it makes it easier for them to pass it on to someone else if they don’t like the book.

Wondering if you should give your recipient a hardcover or a paperback? There is no universal preference among readers. Some like the paperbacks because of the convenience, easy to carry around and travel with. But many people, including me, prefer hardcovers because they’re more traditional and last much longer. A study designed to find a relation between the weight of wine bottles and their prices found that in most cases the weight of a wine bottle related positively with the price. The weight helped consumers perceive the wine as better.

In a word, books can make for memorable gifts. A good book gifted thoughtfully will create a pleasant memory.

7 . About ten years ago, logging into Facebook, Twitter, or Instagram would mostly show posts from friends and family in the order they were posted. Today, these platforms present a mix of content, tailored by algorithms (算法) to match users’ interests, whether it’s plants, sports, cats, or politics.

Kyle Chayka, a writer for The New Yorker, discusses this topic in his book, Filterworld. He explains that algorithms analyze user data to predict and influence what they will likely engage with. This means that instead of a simple, chronological feed, users encounter a dynamic stream, constantly adapting to their preferences. Chayka examines how these algorithmic recommendations control what we consume, from music and movies to food and travel destinations. He argues that this machine-driven selection process has turned us into passive consumers, making our preferences and tastes more similar.

Chayka points out that algorithms make us passive by always showing us content that we’re unlikely to click away from but won’t find too unexpected or challenging. This constant stream of recommendations reduces our exposure to diverse or challenging content, subtly shaping our preferences and behaviors.

Moreover, Chayka points out that algorithms also pressure content creators, like musicians and artists, to tailor their work to fit these digital platforms. For instance, musicians on Spotify or TikTok might focus on creating catchy hooks at the beginning of their songs to grab the listener’s attention.

Despite the strong presence of these algorithms, Chayka believes that regulation could reduce their influence. He suggests that if Meta, the parent company of Facebook, were required to separate its various services, like Instagram or WhatsApp, and make them compete with each other, it could give users more control and choice over their digital consumption.

In summary, the change from simple, time-ordered social. media posts to algorithm-driven content has a big impact on both the viewers and the creators, influencing what we see, hear, and even think. Chayka’s insights highlight the need for greater awareness and potentially more regulation in our increasingly digital world.

8 . Paris mayor Anne Hidalgo has long worked to make her city less dependent on cars. She wanted to see more people using bicycles to get around. Over a number of years, the city government set limits on cars and increased the amount of bike paths from 200 kilometers to over 1,000 kilometers.

This year, Parisians are not complaining about too much automobile traffic. Instead, they say there are too many bikes. “Now, it’s really like a bike traffic jam(阻塞),” Thibault Quere, a spokesperson for France’s Federation of Bicycle Users, said. ”It’s kind of a good difficulty to have, especially when we think about what Paris used to be.”

Some famous roads along the River Seine are completely closed to cars. Now you see people riding bikes, running and walking with their families along the river. In another part of Paris, a bike path on Sebastopol Boulevard is one of the busiest in Europe, after opening in 2019. In one week in early September, it reached a record high of 124,000 riders.

The city will host the Summer Olympics in 2024 and plans to add more bike paths by then. Paris wants to reduce its pollution by half during the games, even as visitors from around the world will be in the city for the event. Organizers say all of the competition sites will be reachable by bike through a 60-kilometer network of bike paths.

The change to Paris, however, has not been easy. With more people using bikes, more people are making mistakes. Some of them are new to cycling and disobey traffic rules. But the environment may be improving. Cycling is good exercise and helps reduce pollution, which is still a problem for the large city. The French government blames atmospheric pollution for 48,000 early deaths in the country each year.

Hidalgo was re-elected in 2020 and plans to keep making what she calls a “Paris that breathes”. Her newest five-year bike plan includes over $250 million for more bike paths and bike parking. The new budget is an increase of over $100 million from her first five-year plan.

9 . Have you ever read your horoscope (占星预言) and thought the predictions were extraordinarily accurate? If so, you’ve experienced the Barnum effect, also called the Forer effect. This psychological phenomenon refers to the tendency of people to believe that unclear, general statements are specific descriptions of themselves. The Barnum effect works exceptionally well for positive statements, as most people enjoy praise and reject criticism. It’s named after American showman P. T. Barnum, who’s strongly associated with the phrase, “There’s a sucker (容易上当的人) born every minute.” This announcement conveys humans are easily tricked by nature and desire to believe the good things they’re told about themselves.

This common cognitive bias (认知偏见) was demonstrated through an experiment conducted by American professor Bertram R. Forer in 1948. His students completed individual personality tests and were told that they would be analyzed and tailored feedback would be returned. Most students evaluated the feedback quality as very accurate. However, Forer had given each student the exact same results! General statements like “You have a great need for people to like and admire you” and “You have a tendency to be critical of yourself’ applied to almost everyone.

We’re used to identifying universally valid statements in astrology (占星术) and fortune-telling, but where else can we see the Barnum effect? Digital platforms like Netflix and Spotify generate content recommendations on our profile. These are partly based on our user history, but they’re also general lists suggested for many users at the same time. However, we’re more likely to consume content when we think it’s personally selected for us!

To avoid being fooled by the Barnum effect, be aware that it’s happening and stay skeptical. Look for specific statements, not general ones. While being fooled may not be detrimental sometimes, avoiding being controlled by the Barnum effect can help prevent us from making decisions that may not be rational or wise.

10 . Most of us look forward to the weekend as a time to relax, connect with friends and family, and handle items from a to-do list that gets unnoticed during the work week. But as the weekday does come to an end, many of us are missing out on enjoying the weekend and instead experiencing a sense of anxiety and even fear for the upcoming week. Experts call this phenomenon Sunday scaries.

Sunday scaries, also known as the Sunday blues, arise when individuals expect the upcoming work week with a combination of various factors such as work-related concerns, unfinished tasks, the end of weekend relaxation, and the pressure to start the new week. As a result, individuals may find it challenging to unwind and relax before the new week begins.

A clinical psychologist, Renée Goff, said, “Sunday scaries are more than a physical heaviness for them, but they could even jump out of their skins due to the upcoming week. The negative emotions associated with Sunday scaries can have a significant impact on one’s mental well-being and overall productivity.”

“As a matter of fact, such anticipatory anxiety is a natural response that happens in preparation for anything that can cause pain or discomfort,” explains psychotherapist Angela Ficken. “Sunday scaries might even start bubbling up as early as Saturday, but tend to become less intense by the time Monday morning rolls around when you start your work week. This doesn’t mean we leave them unchecked.”

To battle anticipatory anxiety for the upcoming week, individuals can adopt self-care practices that promote relaxation and stress reduction. This may include engaging in hobbies, spending time in nature, exercising, practicing mindfulness or simply dedicating time to disconnect from work-related thoughts. Additionally, we can organize tasks for the upcoming week in advance to create a sense of control, reduce the Sunday scaries and promote a healthier work-life balance.
