Nowadays airfare isn't getting any cheaper with fuel costs rising every day. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.

    More and more comment(评论) sections are being shut down online.

    Autumn Phillips had had enough. On August 19, the executive editor of the Quad-City Times in Iowa, and Illinois, US visited her website, qutimes. com, and saw a story about a man who had been shot to death. When she got to the readers' comments section at the end, she was shocked by what she saw. Below the story was a growing string of comments—a racist remark about democratic( 民主的) voters, a negative comment about police...So Phillips decided to do something she had been thinking about for a long time: she shut down the comment section.

    Phillips was not alone in making such a move. Last week, NPR announced it too was closing its online comments section. The decisions don't mean that the news outlets are no longer interested in what their audiences are thinking. Both stressed their eagerness to hear from readers and listeners on social networks. But both agreed that comments had deviated from their original intention. And so they had.

    In the early days of digital journalism, comments were seen as a key part of the new media, a wonderful opportunity for strengthening the dialogue between news producers and their audiences. It was a welcome change, given that for long many news organizations were far too separated from their readers. Much more back and forth conversation seemed like healthy and welcome evolutions. Sadly, that's not the way things turned out. Rather than a place for exchanging ideas, comments sections became the home of ugly name-calling, racism and anti-women language. Besides their poisonous quality, comments seem out of place today.

    “Since we made the announcement, I've received an outpouring of responses from our readers,”she says. “I've heard from parents whose children were hurt by our online comments. I've heard from people who said they wouldn't send in letters to the editor because they were attacked so fiercely by comments, and it wasn't worth it.”

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

    On Sept. 19 the Westchase Elementary PTA（Parent-Teacher Association）will hold its Wizard Walk. The Wizard Walk is a locally organized, healthy alternative to traditional product sales that will raise money to support all PTA programs and events for the year. Remaining money will be applied to an on-going capital campaign to build a new playground.

    The Wizard Walk will take place on Wednesday, Sept. 28, from 8 a. m. to noon at the Westchase Recreation Center Field.  Volunteers will be needed throughout the event.  Look for more Wizard Walk information and volunteer sign-up links in your student's folder, or contact（联系）Laura Kohler at president＠ westchasepta. org.

    The PTA is also holding a year-long Spirit Stick fundraiser（资金筹集活动）. Spirit Sticks are small and students can display them on a key ring on their backpacks, which represent a variety of interests and accomplishments. There will be many ways to earn a Spirit Stick （good grades, great behavior, exceptional attendance, etc.）and opportunities to purchase the limited edition sticks for just $1 every Friday in the courtyard. For more information, contact Nikki Pivnichny at fundraising@ westchasepta. org.

    In addition to new fundraising programs, the PTA is partnering with our Guidance Counselor, Mrs. Kiersten Rivenburg, on a new campaign called Kindness Counts. Look for new recognitions and rewards as we continue to promote kindness from our children, staff and parents throughout the year. For more information, contact Laura Smith at kindnesscounts@ westchasepta. org.

    Now in its eighth year, the After-School Enrichment Program（ASE）is bringing back some favorite programs and offering some new ones. Students will have the opportunity to explore and develop a variety of new interests. Class schedules will be available soon. Registration starts on Sept. 7. Fall session begins Sept. 21 -22. For more information, contact Jennifer Newman at ase@ westchasepta. org.

    If you feel sick or uncomfortable, you might seek out a doctor. But what to do if you don't quite know where you fit into this world and you're tired of carrying that burden alone?

    I answered strangers' questions on life puzzles at the entrance to the New York City subway at 57th and 8th. A group of strangers had stopped by because they were carrying around some deep, meaningful questions that had long gone unanswered, like "why can't I be happier in my life?"

    And then I spotted her, who would be my toughest questioner of the day. She was about 6 years old and held her mother's hand as she craned (伸长脖子) her neck to stare at us. Her mother stopped, but the girl hesitated. "It's OK," I offered. "Do you have a question?" The girl smiled at her mother, then let go of her hand to walk over towards us. She looked me dead in the eye and said: "How do I know I'm real?"

    Suddenly I was back in graduate school. Should I talk about the French philosopher Rene Descartes to prove our existence, with the phrase "I think, therefore I am?" Or, mention English philosopher G. E. Moore and his famous "here is one hand, here is the other," to prove the existence of the external world? But then the answer came to me. I remembered that the most important part of philosophy was feeding our sense of wonder. "Close your eyes," I said. She did. "Well, did you disappear?" She smiled and shook her head, then opened her eyes. "Congratulations, you're real."

    She grinned (露齿而笑) broadly and walked over to her mother, who looked back at us and smiled.

    What's the one thing every child wants in school? More breaks! And that is exactly what some schools are giving students, which turns out to be beneficial for everyone. Eagle Mountain Elementary School in Fort Worth, Texas, is one of four public schools carrying out the LiiNK program, a project that increases breaks per day to improve creativity, develop character, and heighten school success.

    LiiNK was inspired by Scandinavian approaches to learning based on the simple concept （观念）of giving children more outside playtime and less time spent indoors. In Finland, where the system has been in place for decades, students have some of the highest scores on global assessment tests. Instead of spending increasing amounts of time inside the classroom, they're putting more and more focus on physical activity. Finnish kids get to enjoy 15 minutes of playtime for every hour of class.

    After spending six weeks in Finland in 2016, Debbie Rhea, the creator of LiiNK and professor at Texas Christian University, discovered that the additional breaks of "outdoor play" actually helped students improve their performance inside the classroom. "You start putting 15 minutes into these kids every so often and it gives the platform for them to be able to function at their best level," she says.

    Other studies have shown that outdoor playtime decreases restlessness, anxiety, and has a whole other benefits such as improved motor skills, physical fitness, and social development. Rhea started carrying out the program in private schools in 2017, and has since expanded her program to districts in Texas, Oklahoma, Minnesota, and Utah and the children in these schools are all the happier for it. It just goes to show that the best way to raise happy and successful children, is to simply let them be kids every once in a while.
