Working at home in your nightclothes while saving hundreds of dollars may sound too good to be true, but it isn’t. More and more employees are telecommuting, doing their job at home or another remote site.
"It’s a trend that’s here now and you’re going to see a lot more telecommuting because people don’t have to put up with commuting (来回上下班). They want more work/life balance, they want less stress in their lives and companies want to drive costs after their bottom lines," says John Edwards, President of the International Telework Association and Council.
However, Edwards says, "The biggest problem at the moment is dealing with middle management who is uncomfortable with management style focusing on results. They are used to the line of sight management style. But they have to change to more results-oriented management style which can often be slightly opposite, so they feel uncomfortable with that."

[单选题]Passage 2
Taylor Swift, the seven-time Grammy winner, is known for her articulate lyrics, so there wasnothing surprising about her writing a long column for The Wall Street Journal about the future ofthe music industry. Yet there′ s reason to doubt the optimism of what she had to say "This moment in music is so exciting because the creative avenues an artist can explore arelimitless," Swift wrote."In this moment in music, stepping out of your comfort zone is rewarded,and sonic evolution is not only accepted ... it is celebrated. The only real risk is being too afraid totake a risk at all."
That′s hard to reconcile with Nielsen′s mid-year U.S. music report, which showed a 15percent year-on-year drop in album sales and a 13 percent decline in digital track sales. This couldbe the 2013 story all over again, in which streaming services cannibalize their growth from digitaldownloads, whose numbers dropped for the first time ever last year, except that even includingstreams, album sales are down 3.3 percent so far in 2014. Streaming has grown even more than it didlast year,42 percent compared to 32 percent, but has failed to make up for a general loss of interestin music.
Consider this: in 2014 to date, Americans purchased 593.6 million digital tracks and heard 70.3million video and audio streams for a sum total of 663.9 million. In the comparable period of 2013,the total came to 731.7 million.
Swift, one of the few artists able to pull off stadium tours, believes it′s all about quality.
"People are still buying albums, but now they′ re buying just a few of them," she wrote. "They arebuying only the ones that hit them like an arrow through the heart."
In 2000, album sales peaked at 785 million. Last year, they were down to 415.3 million. Swiftis right, but for many of the artists whose albums pierce hearts like arrows, it′s too late. Sales ofvinyl albums have increased 40.4 percent so far this year, according to Nielsen, and the top-sellingone was guitar hero Jack White′ s Lazaretto. The top 10 also includes records by the aging or dead,such as the Beatles and Bob Marley & the Wailers. More modern entries are not exactly teensensations, either: the Black Keys, Beck and the Arctic Monkeys. None of these artists is present onthe digital sales charts, including or excluding streams. The top-selling album so far this year, by ahuge margin, is the saccharine soundtrack to the Disney animated hit, "Frozen".
When, like me, you′re over 40 and you believe the music industry has been in decline since in1993 (the year Nirvana released in Utero), it′ s easy to criticize the music taste of "the kids thesedays," a term even the 23-year old Swift uses. My fellow dinosaurs will understand if they compare1993′s top albums to Nielsen′s 2014 list. But these kids don′t just like to listen to different musicthan we do, they no longer find much worth hearing.
The way the music industry works now may have something to do with that. In the old days,musicians showed their work to industry executives, the way most book authors still do to publishers(although that tradition, too, is eroding). The executives made mistakes and were credited with brilliantfinds. Sometimes they followed the public taste, and sometimes they strove to shape it, taking bigfinancial and career risks in the process. These days, according to Swift, it′s all about the socialnetworks. "A friend of mine, who is an actress, told me that when the casting for her recent movie camedown to two actresses, the casting director chose the actress with more Twitter followers," Swift wrote.
"In the future, artists will get record deals because they have fans--not the other way around."
The social networks are fickle and self-consciously sarcastic(see the recent potato saladphenomenon). They are not about arrow-through-the-heart sincerity. That′ s why YouTube made Psya star, but it couldn′t have been the medium for Beatle mania. Justin Timberlake has 32.9 millionTwitter followers, but he′ s no Jack White.
In the music industry′ s heyday, it produced a lot of schlock. But it got great music out to themasses, too. These days, it expects artists to do their own promotion and for those who less good atthat than at making music, it may mean not getting heard. For fans it means less good music tostream and download. Well, there′s always the warm and fuzzy world of vinyl nostalgia, I guess.
