Auto-Tune: Why Pop Music Sounds Perfect

If you haven?t been listening to pop radio in the past few months, you?ve mi ssed the rise of two seemingly opposing trends. In a medium in which mediocre (平庸的) singing has never been a bar to entry, a lot of pop vocals suddenly sound great. Better than great: note- and pitch-perfect, as if there?s been an unspoken tightening of standards at record labels or an evolutionary leap in the development of vocal cords. At the other extreme are a few hip-hop singers who also hit their notes but with a precision so exaggerated that on first listen, their songs sound comically artificial, like a chorus of …50s robots singing Motown.

The force behind both trends is an ingenious plug-in called Auto-Tune, a downloadable studio trick that can take a vocal and instantly nudge it onto the proper note or move it to the correct pitch. It?s like Photoshop for the human voice. Auto-Tune doesn?t make it possible for just anyone to sing like a pro, but used as its creator intended, it can transform a wavering(颤抖的) performance into something technically flawless. “Right now, if you listen to pop, everything is in perfect pitch, perfect time and perfect tune,” says producer Rick Rubin. “That?s how widespread Auto-Tune is.”

Auto-Tune?s inventor is a man named Andy Hildebrand, who worked for years interpreting seismic (i.e. relating to earthquakes) data for the oil industry. Using a mathematical formula called autocorrelation, Hildebrand would send sound waves into the ground and record their reflections, providing an accurate map of potential drill sites. It?s a technique that saves oil companies lots of money and allowed Hildebrand to retire at 40. He was debating the next chapter of his life at a dinner

party when a guest challenged him to invent a box that would allow her to sing in tune. After he worked on autocorrelation for a few months, Auto-Tune was born in late 1996.

Almost immediately, studio engineers adopted it as a trade secret to fix flubbed (搞砸了的) notes, saving them the expense and trouble of having to redo sessions. The first time common ears heard Auto-Tune was on the immensely irritating 1998 Cher hit “Believe.” In the first verse, when Cher sings “I can?t break through” as though she?s standing behind an electric fan, that?s Auto-Tune — but it?s not the way Hildebrand meant it to be used. The program?s retune speed, which adjusts the singer?s voice, can be set from zero to 400. “If you set it to 10, that means that the output pitch will get halfway to the target pitch in 10 milliseconds,” says Hildebrand. “But if you let that parameter go to zero, it finds the nearest note and changes the output pitch instantaneously” —eliminating the natural transition between notes and making the singer s ound jumpy and automated. “I never figured anyone in their right mind would want to do that,” he says.

Like other trends set by Cher, the creative abuse of Auto-Tune quickly went out of fashion, although it continued to be an indispensable part of the engi neer?s toolbox. But in 2003, T-Pain (Faheem Najm), a little-known rapper and singer, accidentally stumble onto the Cher effect while Auto-Tuning some of his vocals. “It just worked for my voice,” says T-Pain in his natural Tallahassee accent. “And there wasn?t anyone else doing it.”

Since his 2005 first album, T-Pain has sent a dozen mechanically cheery singles into the Top 10. He contributed to four nominated songs at this year?s Grammys on Feb. 8, and his influence is still spreading. When Kanye West was looking for an effect to match some heartbroken lyrics, he flew T-Pain to Hawaii to see how many ways they could adjust Auto-Tune. Diddy gave a percentage of his upcoming album?s profits to T-Pain in exchange for some lessons. Even Prince is rumored to be experimenting with Auto-Tune on his new record. “I know Auto-Tune) better than anyone,” says T-Pain. “And even I?m just figuring out all the ways you can use it to change the mood of a record.”

Rubin, who?s produced artists as diverse as the Dixie Chicks and Metallica, worries that the safety net of Auto-Tune is making singers lazy. “Sometimes a singer will do lots of takes when they?re recording a song, and you really can hear the emotional difference when someone does a great performance vs. an average o ne,” says Rubin. “If you?re pitch-correcting, you might not bother to make the effort. You might just get it done and put it through the machine so it?s all in tune.” Rubin has taken to having an ethical conversation before each new recording session. “I e ncourage artists to embrace a natural process,” he says.

With the exception of Milli Vanilli?s, pop listeners have always been fairly indulgent about performers? ethics. It?s hits that matter, and the average person listening to just one pop song on the radio will have a hard time hearing Auto-Tune?s impact; it?s effectively deceptive. But when track

after track has perfect pitch, the songs are harder to differentiate from one another — which explains why pop is in a pretty serious lull (停滞) at the moment. It also changes the way we hear unaffected voices. “The other day, someone was talking about how Aretha Franklin at the Inauguration was a bit pitchy,” says Anderson. “I said, …Of course! She was singing!? And that was a musician talking. People are gettin g used to hearing things dead on pitch, and it?s changed their expectations.”

Despite Randy Jackson?s stock American Idol critique —“A little pitchy, dawg” —many beloved songs are actually off-pitch or out of tune. There?s Ringo Starr on “With a Little H elp from My Friends,” of course, and just about every blues song slides into notes as opposed to hitting them dead on. Even Norah Jones, the poster girl of pure vocals, isn?t perfect. “There?s some wonderful imperfections of pitch on …Don?t Know Why? from Come Away with Me,” says Anderson, “and most of the other tunes on the album as well. But I wouldn?t want to change a single note.”

Let?s hope that pop?s fetish for uniform perfect pitch will fade, even if the spread of Auto-Tune shows no signs of slowing. A $99 version for home musicians was released in November 2007, and T-Pain and Auto-Tune?s parent company are finishing work on an iPhone app. “It?s gonna be real cool,” says T-Pain. “Basically, you can add Auto-Tune to your voice and send it to your friends and put it on the Web. You?ll be able to sound just like me.” Asked if that might render him no longer unique, T-Pain laughs: “I?m not too worried. I got lots of tricks you ain?t seen yet. It?s everybody else that needs to step up their game.”

Part IV Reading Comprehension (Reading in Depth) (25 minutes) Section A

Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2.

Questions 47 to 51 are based on the following passage.

More than two million people in Europe now have fibre broadband direct to their home, suggests a survey.

The latest figures on superfast broadband delivered by fibre to the home (FTTH) shows 18% growth over the last survey compiled in late 2008.

The continued growth suggests that the global economic downturn has not hit plans to build a fibre infrastructure (基础设施).

Sweden tops the list of nations rolling out the technology, with 10.9% of its broadband customers using fibre.

Karel Helsen, president of Europe?s Fibre-To-The-Home Council, said the growth matched predictions that were revised when the credit crunch (信用紧缩) started to make itself felt.

“The numbers in 2009 are in line with the latest forecasts,” said Mr. Helsen.

By 2012, the FTTH Council expects that 13 million people across 35 European nations will have their broadband delivered by fibre. Such services would start at speeds of 100 megabits per second (mbps), said Mr. Helsen.

Around Europe more than 233 projects were underway to lay the fibres that would connect homes or buildings to the net, said Mr. Helsen. Many of those, he said, were being operated by local governments or smaller net firms.

Local governments were interested in FTTH because of the economic and social benefits it brought in its wake, said Mr. Helsen.

The low latency or delay inherent in high-speed fibre networks made possible novel uses of broadband, he said. “No delay is very important,” he said, “specifically if you talk about applications that are time-dependent such as personal communications, conference calls or video calls where delays cause a lot of interference.”

While early FTTH services were concentrated in cities, said Mr. Helsen, many more were reaching out to rural areas for e-health and e-learning projects.

Separate studies show that an FTTH infrastructure can have a direct impact on local economic output, said Mr. Helsen.

The UK, France and Germany have yet to break into the list of top ten FTTH nations.

﹡TOP FIBRE NATIONS:

1) Sweden - 10.9% 2) Norway - 10.2% 3) Slovenia - 8.9% 4) Andorra - 6.6% 5) Denmark- 5.7% 6) Iceland - 5.6% 7) Lithuania - 3.3% 8) Netherlands - 2.5% 9) Sl ov aki a - 2.5% 10) Finland - 2.4%

Section B

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2with a single line through the centre.

Passage One

Questions 52 to 56 are based on the following passage.

Musicians — from karaoke singers to professional cello players — are better able to hear targeted sounds in a noisy environment, according to new research that adds to evidence that music makes the brain work better.

“In the past ten years there?s been an explosion of research on music and the brain,” Aniruddh Patel, Senior Fellow at the Neurosciences Institute in San Diego, said today at a press briefing.

Most recently brain-imaging studies have shown that music activates many diverse parts of the brain, including an overlap in where the brain processes music and language.

Language is a natural aspect to consider in looking at how music affects the brain, Patel said. Like music, language is “universal, there?s a strong learning component, and it carries complex meanings.”

For example, brains of people exposed to even casual musical training have an enhanced ability to generate the brain wave patterns associated with specific sounds, be they musical or spoken, said study leader Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University in Illinois.

But for people without a trained ear for music, the ability to make these patterns decreases as background noise increases, experiments show. Musicians, by contrast, have subconsciously trained their brains to better recognize selective sound patterns, even as background noise goes up.

At the same time, people with certain developmental disorders, such as dyslexia (诵读困难), have a harder time hearing sounds amid the continuing loud confused noise —a serious problem, for example, for students straining to hear the teacher in a noisy classroom.

Musical experience could therefore be a key therapy for children with dyslexia and similar language-related disorders, Kraus said.

In a similar vein, Harvard Medical School neuroscientist Gottfried Schlaug has found that stroke patients who have lost the ability to speak can be trained to say hundreds of phrases by singing them first.

In research also presented today at the AAAS meeting Schlaug demonstrated the results of

intensive musical therapy on patients with lesions (损伤) on the left sides of their brains, those areas most associated with language.

Before the therapy, these stroke patients responded to questions with largely incoherent sounds and phrases. But after just a few minutes with therapists (治疗师), who asked them to sing phrases and tap their hands to the rhythm, the patients could sing “Happy Birthday,” recite their addresses, and communicate if they were thirsty.

“The underdeveloped systems on the right side of the brain that respond to music became enhanced an d changed structures,” Schlaug said.

Overall, Schlaug said, the experiments show that “music might be an alternative medium for engaging parts of the brain that are otherwise not engaged.”

52. What do we learn from the first paragraph?

A) Music training can improve the function of the brain.

B) Singers or instrument players tend to have better hearing.

C) There has been little evidence to prove the power of music.

D) Musicians are born with ability to hear targeted sound amid noise.

53. According to Aniruddh Patel, language is usually under consideration when ________.

A) musicians explain the complex meaning behind the music

B) therapists try to treat patients who suffer from stroke

C) people research the connection between music and the brain

D) researchers study the functions of different parts of the brain

54. Whether people can hear selective sounds amid noise depends on their ability to ________.

A) neglect the influence of the noise B) remember the meaning of the sounds

C) make the associated brain wave patterns D) tell musical sounds from spoken ones

55. According to Kraus, the significance of identifying the link between music and brain is that

________.

A) music training can be a way to enhance poor hearing

B) singing can be used to treat people with language disorders

C) intensive musical therapy may make a mute person speak

D) all brain disorders can be cured by learning musical sounds

56. The musical training therapists gave to the stroke patients actually _______.

A) enhanced the parts of the left brain which are under constant use

B) restored the language function of the damaged system in the left brain

C) hindered the damaged systems in the brain from deteriorating sharply

D) changed the structures of the underdeveloped systems in the right brain

Passage Two

Questions 57 to 61 are based on the following passage.

As Sesame Street kicks off its 40th anniversary season Tuesday, with first lady Michelle Obama and Broadway star Lin-Manuel Miranda as guests, it is indisputably the most be loved children?s show in history, and one of television?s biggest and most enduring success stories.

The series holds a record 122 Emmy Awards, not including a lifetime-achievement trophy (奖±) award, and has been adapted in more than 120 countries and territories around the globe. An estimated 100,000 Sesame products have been made available internationally, from T-shirts and costumes to high-tech toys such as Elmo Live.

Sesame’s cross-cultural, multi-generational appeal has a lot to do with the specific age group it targets. “The bulk of our audience is in the 2s and 3s, though we shoot for 2 to 4,” says executive producer Carol-Lynn Parente. At that early stage, says Spinney — who is 75, and has been with the show since Day 1 (he plays Oscar as well) —“children are basically the same, and have been through the years.”

But if preschoolers? fundamental needs and sensibilities haven?t changed much, the world around them has —not least of all on the media landscape, where Sesame Street now competes with many other kids? shows and an ever-expanding array of new media.

In 2000, the Children?s Television Workshop, the organization through which creator Joan Ganz Cooney launched Sesame Street on PBS predecessor NET, changed its title to Sesame Workshop, to reflect its expansion into the digital, interactive age.

Content and presentation continue to evolve on TV as well. The show?s famously catchy theme song, Sunny Day, now has a hip-hop beat and a jazzier arrangement. Parente stresses that it?s just as important “to keep our curriculum current. The ABC?s and 123?s are always there, but we stay relevant by incorporating other things that are interesting and meaningful.”

“We focus on all aspects of d evelopment — cognitive needs, social and emotional needs, health needs —and bring in advisers who are experts in each area, to make sure we?re age-appropriate,” says Rosemarie Truglio, vice president of education and research, Sesame Workshop. “But we nev er talk down to children, and we?re not afraid to explore sensitive topics.”

Sesame has had its critics in the academic community as well.

For Mary Lynn Crow, a clinical psychologist and professor of education at the University of Texas-Arlington, “shows l ike Sesame Street lack the potentially deep, personal emotional imprint (影响) that can and should occur between a student and teacher in an early educational experience.”

On the other hand, Crow considers Sesame Street“a beautiful model of what I call high-tech learning. They can teach children about letters, numbers, color and size through repetition in ways traditional education can?t, and provide early information about attitudes, values and relationships.”

57. What do we learn about Sesame Street from the first two paragraphs?

A) It rose to fame because of the first lady?s role.

B) It?s successful and gains international popularity.

C) It still has to win a lifetime-achievement award.

D) It is the most successful show in American history.

58. What?s Spinney?s opinion on the target audience of Sesame Street?

A) They are completely different than they were 40 years ago.

B) Many of them are devoted fans of the performance.

C) Their basic needs haven?t changed much through years.

D) They continue to watch the show when they have grown up.

59. The author says that in the current world, Sesame Street _______.

A) has slight edge over other shows targeting children

B) has made some changes so as to keep up with the times

C) tries to cater to adults who accompany their children to the show

D) is doomed to fail due to its out-dated content and presentation

60. What can be inferred about Sesame Street from Rosemarie Truglio?s words?

A) It tries to prepare children both for school and life?s lessons.

B) Its writer has changed the theme of the story for kids.

C) Children seem to be looked down upon in the show.

D) Sensitive topics have always been banned in the show.

61. Mary Lynn Crow is negative about Sesame Street because she thinks it _______.

A) only touches up superficial relationships

B) is too complicated for children to understand

C) goes against ways of traditional education

D) repeats basic knowledge over and over again

Career or Marriage?

A growing number of female college students are choosing to get married soon after they graduate from college. So while other students are busy with seeking jobs, they are busy with blind dating. Of course, most of them are looking for their Mr. Rights who are wealthy.

More often, the reason why many new female grads are choosing marriage the time they get out of school is all about the employment pressure. Due to the tough job market, many female grads feel great pressure to find a good job after graduation. They choose to pick rich men as their dates in the hope of living away from the work pressure. Besides, because the future as an adult seems scary, it feels so much easier to face things with a spouse, especially a rich one.

In my opinion, college students who are facing an uncertain future may see marriage as a way to make the transition from school to the society easier —but it?s not. There are all kinds of bad, bad reasons to get married, and this is one for them.

四级考前冲刺试题一

四级考前冲刺试题一 1. 有人认为公交车上年轻人必须给老人让座 2. 有人认为年轻人没有义务给老人让座 3. 你的看法Is Offering Seats Compulsory for Young Passengers? Eat an Apple (Doctor’s Orders) The farm stand is becoming the new apothecary (药剂师), preparing and giving out apples — not to mention vegetables such as artichokes, asparagus and arugula — to fill a novel kind of prescription. Doctors at three health centers in Massachusetts have begun advising patients to eat “prescription produce” from local farmers’ markets, in an effort to fight obesity (when someone is very fat in a way that is unhealthy) in children of low-income families. Now they will give coupons (赠券) amounting to $1 a day for each member of a patient’s family to promote healthy meals. “A lot of these kids have a very limited range of fruits and vegetables that are acceptable and familiar to them. Potentially, they will try more,” said Dr. Suki Tepperberg, a family physician at Codman Square Health Center in Dorchester, one of the program sites. “The goal is to get them to increase their consumption of fruit and vegetables by one serving a day.” The effort may also help farmers’ markets compete with fast-food restaurants selling dollar value meals. Farmers’ markets do more than $1 billion in annual sales in the United States, according to the Agriculture Department. Massachusetts was one of the first states to promote these markets as hubs of preventive health. In the 1980s, for example, the state began issuing coupons for farmers’ markets to low-income women who were pregnant or breast-feeding or for young children at risk for malnutrition (营养不良). Thirty-six states now have such farmers’ market nutri tion programs aimed at women and young children. Thomas M. Menino, the mayor of Boston, said he believed the new children’s program, in which doctors write vegetable “prescriptions” to be filled at farmers’ markets, was the first of its kind. Doctors will track participants to determine how the program affects their eating patterns and to monitor health indicators like weight and body mass index, he said. “When I go to work in the morning, I see kids standing at the bus stop eating chips and drinking a soda,” Mr. Menino said in a phone interview earlier this week. “I hope this will help them change their eating habits and lead to a healthier lifestyle.” The mayor’s attention to healthy eating dates to his days as a city councilman. Most recently he has app ointed a well-known chef as a food policy director to promote local foods in public schools and to foster market gardens in the city. Although obesity is a complex problem unlikely to be solved just by eating more vegetables, supporters of the vegetable coupon program hope that physician intervention will spur young people to adopt the kind of behavioral changes that can help prevent lifelong obesity. Childhood obesity in the United States costs $14.1 billion annually in direct health expenses like prescription drugs and visits to doctors and emergency rooms, according to a recent article on the economics of childhood obesity published in the journal Health Affairs. Treating obesity-related illness in adults costs an estimated $147 billion annually, the article said. Although the vegetable prescription pilot project is small, its supporters see it as a model for encouraging obese children and their families to increase the volume and variety of fresh produce they eat. “Can we help people in low-income areas, who shop in the center of supermarkets for low-cost empty-calorie food, to shop at farmers’ markets by making fruit and vegetables more affordable?” said Gus Schumacher, the chairman of Wholesome Wave, a nonprofit gro up in Bridgeport, Conn., that supports family farmers and community access to locally grown produce. If the pilot project is successful, Mr. Schumacher said, “farmers’ markets would become like a fruit and vegetable pharmacy (药房) for at-risk families.” The pilot project plans to enroll up to 50 families of four at three health centers in Massachusetts that already have specialized children’s programs called healthy weight clinics. A foundation called CAVU, for Ceiling and Visibility Unlimited, sponsors the clinics that are administering the vegetable project. The Massachusetts Department of Agriculture and Wholesome Wave each contributed $10,000 in seed money. (Another arm of the program, at several health centers in Maine, is giving fresh produce coupons to pregnant mothers.) The program i s to run until the end of the farmers’ market season in late fall. One month after Leslie-Ann Ogiste, a certified nursing assistant in Boston, and her 9-year-old son, Makael Constance, received their first vegetable prescription coupons at the Codman Center, they have lost a combined four pounds, she said. A staff member at the center told Ms. Ogiste about a farmers’ market that is five minutes from her apartment, she said. “It worked wonders,” said Ms. Ogiste, who bought and prepared eggplant, cucumbers, tomatoes, summer squash, corn, bok choy, parsley, carrots and red onions. “Just the variety, it did help.” Ms. Ogiste said she had minced some vegetables and used them in soup, pasta sauce and rice dishes — the better to disguise the new good-for-you foods that she served her son. Makael said he did not mind. “It’s really good,” he said. Some nutrition researchers said that the Massachusetts project had a good chance of improving eating habits in the short term. But, they added, a vegetable prescription program in isolation may not have a long-term influence on reducing obesity. Families may revert to their former habits in the winter when the farmers’ markets are closed, these researchers said, or they may not be able to afford fresh pr oduce after the voucher program ends. Dr. Shikha Anand, the medical director of CAVU’s healthy weight initiative, said the group hoped to make the veggie prescript ion project a year-round program through partnerships with grocery stores. But people tend to overeat junk food in higher proportion than they undereat vegetables, said Dr. Deborah A. Cohen, a senior natural scientist at the RAND Corporation. So, unless people curtail (减少) excessive consumption of salty and sugary snacks, she said, behavioral changes like eating more fruit and vegetables will have limited effect on obesity.

2020年大学英语六级考试冲刺练习:阅读篇1 Passage one(The only way to travel is on foot) The past ages of man have all been carefully labeled by anthropologists. Descriptions like ‘ Palaeolithic Man’, ‘Neolithic Man’, etc., neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label ‘Legless Man’. Histories of the time will go something like this:‘in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts and escalators in all large buildings to prevent people from walking. This situation was forced upon earth dwellers of that time because of miles each day. But the surprising thing is that they didn’t use their legs even when they went on holiday. They built cable railways, ski-lifts and roads to the top of every huge mountain. All the beauty spots on earth were marred by the presence of large car parks. ’ The future history books might also record that we were deprived of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird’s-eye view of the world – or even less if the wing of the aircraft happens to get in your way. When you travel by car or train a blurred image of the countryside constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop. Is it the lure of the great motorways, or what? And as for sea travel, it hardly deserves mention. It is perfectly summed up in the words of the old

大学英语六级如何过

大学英语六级如何过 大六级考试作为一项全国性的教学考试由“国家部高教大学英语六级考试试卷司”主办,每年各举行两次。下面是 ___的大学英语六级如何过的方法,希望对大家有帮助。 有不少的同学总是抱怨自己英语基础不好,将考不过四六级的原因归结于此。可是,基础不好就真的不能过级了吗?同学们,基础不好的话,可以慢慢培养语感;面对考试,关键是计划和做题策略。 我的英语基础不好,但我顺利通过了去年年末的那次英语六级考试,这与我制订考前复习计划和在考试中讲求做题策略有很大关系。 “态度一切。”这是不变的真理。做什么事情都是如此,六级备考也不例外。 我的许多同学通过四级考试时并未认真准备,是"一不小心"跨过了四级门槛,因此错误地以为六级考试也能"碰巧过关",结果可想而知,只能以失败告终。道理很简单,英语四级考试的词汇与题型其实在高考的时候就有所体现。经过了高考,许多人的英语基础都还很好,大学只要稍加巩固,花小力气就能取得大成果。但六级考试却是在大学英语的基础上出题,它需要扎实的单词记忆和各种题

型的深化训练,丝毫没有投机取巧的成分,抱着侥幸心理准备六级考试,当然不能。 我的第一次六级考试就是因为自己的疏忽而一败涂地。我自己分析了原因:没有扎实准备,想靠运气过关,利用了里的"小概率论",成功率当然为零。 由于每个人的具体情况不同,所以每个人的也不一样,但不管什么样的学习方法,考试前制订复习计划是必须的。我自己给自己制订的六级考试的复习计划包括两部分:单词记忆和做习题。 先说单词记忆。背单词要有正确的方法。我看到身边的很多同学,成天拿着一本六级词汇书读、背,可快到考试了单词还没背完,而前面已经背过的也忘得差不多了。我的方法是先利用迈西英语速记一遍,然后重点在阅读中加强记忆。单纯地背单词既浪费时间和精力,效果也很差;而单纯地在阅读中记忆,则会漏掉一些重要的词汇。我建议先花一个月的时间把词汇书看一遍,为了节省时间,你也可以用像迈西背单词软件这样的工具速记一遍单词,目的在于可以在脑子里有个大致的印象,然后在大量的阅读中不断地加深记忆。

六级考前冲刺

6级考前冲刺试题二 Dogs Make Employees More Productive At Work Leib Lurie never intended for his company, message delivery service One Call Now, to be pet-friendly. But his dog, Ivy, had other ideas. Five years ago, the German shepherd showed up unannounced at One Call Now?s Troy, Ohio-based office—a 1.5-mile trek from Lurie?s home. When he continued to make the trip each day he wasn?t brought to the office, Lurie realized it was time for a change in company policy. Today, four or five employee?s dogs, as well as a variety of fish, birds, and other caged animals join Ivy in the office daily to make One Call Now a workingman?s menagerie (动物园). “They?re not very good at sending voice messages,” Lurie jokes of the pets in his office. “But we?ve gotten them down with using the computer, at least the point part.” One Call Now joins a growing force of companies across the United States to welcome pets in the workplace. While only 17 percent of U.S. employers currently allow animals in the workplace, according to a survey from the American Pet Products Manufacturers Association, pet-friendly, often specifically dog-friendly, environments are building steam. From major companies like Google, Zynga, and https://www.360docs.net/doc/044322612.html, to growing start-ups, more and more canine companions are showing up to work. For many entrepreneurs, the inception of a dog-friendly environment begins long before offices enter the picture. “My dog, Blueberry, was the founding dog,” explains Randy Hetrik, founder of TRX Training. “Literally, it was him and me before any other people came in, so he takes great pride in what we?ve accomplished.” As Hetrik built his company, he never forgot his first partner. Today, up to ten dogs wander with Blueberry through the four floors of TRX?s San Francisco office. Many pet-friendly work environments develop as a part of the company?s larger mission or company culture. After spending years in uptight corporate climates, Nancy Squires founded her own consulting firm, The Squires Group, with a distinctly homey atmosphere, which included her two Italian greyhounds. Marketing software company G5?s dog-friendliness fits into the animal-friendly climate of their mountain town Bend, Oregon, as well as the company?s own cultural backbone. “We try to have a culture that promotes freedom for the employees and helps them thrive,” says G5 CEO Dan Hobin. “If that involves bringing your dog to work, bring your dog to work.” Having dogs underfoot might seem to some like a distraction, but advocates of animals in the workplace see quite the opposite. Dogs in the office foster friendlier, more collaborative work environments. At G5, this includes dogs posing as mascots for the company?s various divisions. “Everyone rallies around the dogs,” Hobin says. Employees surrounded by dogs also have a tendency to rally around their jobs. According to a survey of 50 small and large companies by the American Pet Products Manufacturers Association in 2008, companies that allow pets in the workplace see a lower rate of employee absenteeism (旷工) and more willingness to work longer hours. “There are a lot of people who know they have to spend extra hours at work, particularly in this economic climate,”says Debrah Schnackenberg, vice president of emergency services for the American Humane Association. “People feel comfortable spending that extra hour or two at the office when they know their dog is right there with them.” Dog-friendliness may generate more loyalty for the company as a whole. In the last two years, One Call Now has seen a two or three percent turnover rate. Lurie attributes this small number in part to the office pets. “You ask someone who is in a $12-an-hour job, …W ould you work anywhere else??And they say, …No way.? Where else could I bring my dog to work?” he says. This sense of loyalty stems from a simple concept: Dogs make people happy. “They?re always happy to see you, they?re happy for the smallest things, and they?re ever optimistic,”says Hetrik. “Having a dog wandering around just seems to make people smile.”

How to Create a Home Library “I cannot live without books,” declared U.S. President Thomas Jefferson to his friend John Adams. Indeed, Jefferson was an obsessive book collector from a young age, amassing (收集) three separate home libraries in his lifetime. The first collection was destroyed when his family home burned down in 1770. When the Library of Congress was destroyed in the War of 1812, Jefferson sold his second collection of about 6,000 books to the federal library. Jefferson’s librar y was considered the finest in the country, and his collection doubled the holdings of the Library of Congress. Still, Jefferson didn’t let the shelves at Monticello sit empty. By the time he died 11 years later, he had more than 2, 000 volumes in his library. Jefferson’s library might fit your conception of an old-fashioned home library with leather-bound books, wood paneling and uncomfortable furniture. But home libraries can be a dynamic expression of the owner’s pers onality. Creating a home library is a fun way to display your interests while establishing a special space for reading. Home Library Organization When you started using the public library, you probably learned about Melvil Dewey and his system for ordering libraries. The Dewey Decimal Classification System has ten broad categories for organizing books, including philosophy, religion and the arts. Each category is assigned a number, so for example, when you want a book on modern art, you head to the 700 block. Larger libraries, such as those at universities, tend to use the Library of Congress Classification System because it offers a more specific array of subjects for categorization, adding subjects such as medicine and law for a total of 21 categories. Your home library may or may not be as large as your local public library, but a good system of organization will still help you find the book you want quickly. You could take a page from Dewey and the Library of Congress and sort books by subject matter. Sections for subjects such as history, technology or fiction might make their retrieval easier. This system also would allow you to highlight a particular passion, such as an extensive collection of World War II history.
