Zoos and Animal Welfare (Issues That Concern You) - PDF
نویسندگان: خلاصه: Z oos have evolved over time from symbols of power and pres-tige of the early rulers, to institutions for education andresearch, to powerful businesses, and ultimately to a beacon ofhope in a world facing alarming rates of extinction. Yet to some,zoos have always been and continue to be prisons where other-wise healthy animals waste away inside depressing enclosures, fac-ing a lifetime of neglect. These critics will need a lot of convinc-ing to believe that zoos can be beneficial to animals. People canlearn more about the fears of critics and the future of zoos by trac-ing their evolution over time.History of ZoosWild animals have been displayed in captivity for thousands ofyears. According to most sources the first known zoos were largecollections of animals assembled in Egypt around 2500 B.C. Exoticwild animals were captured on expeditions, then displayed in cap-tivity by early rulers as symbols of wealth and power. In 1500 B.C.Queen Hatshepsut of Egypt built a zoo, and about five hundredyears later the Chinese emperor Wen Wang constructed theGarden of Intelligence—an enormous zoo that sprawled over 1,500acres (607ha). Later many smaller zoos were founded by rulers innorthern Africa, India, and China to show off the strength andriches of the current regime.Studies also show that the Romans kept wild animals in cap-tivity and sent them into battle in bloody public spectacles. Lions,bears, elephants, and other creatures were forced to fight to thedeath in public arenas to the cheers and shouts of onlookers.The birth of the modern zoo did not happen until 1828, whenthe London Zoo dedicated itself to the study of captive wildlifein London. The success of the London Zoo set off a wave of sim-ilar establishments, including the first zoological garden in7INTRODUCTIONMelbourne, Australia, and the New York City Zoo. In 1889 theU.S. Congress established the National Zoo for the purpose ofbreeding native wildlife
First Kisses 4: It Had to Be You - PDF
نویسندگان: خلاصه: Chapter OneIam a girly-girl.With three older brothers who areobsessed with sports and cars and videogames, it would have been easy for me to growup a tomboy, but I didn’t.From the time I was little, I’ve loved beinga girl! Dresses with ruffles. Colored tights.Shiny black Mary Janes. I used to wear themall! Very rarely would I wear T-shirts andjeans, but if I did, there was always somethingfeminine about them. Like my jeans wouldn’t1be blue. They’d be yellow or purple andtrimmed with lace on the cuffs. And my T-shirts would say things like: DADDY’S LITTLEGIRL or SWEET AS SUGAR.I used to have tea parties with my stuffedanimals and I would serve cakes made with myEasy-Bake oven. Cliché, I know. I even hadevery Barbie imaginable, including all theaccessories, as well as a few Bratz dolls.Confession: I always loved my Barbies morethan my Bratz dolls. Barbie just seemed moreelegant. And she had her own Dream House!I’ve always had pierced ears. My oldestbrother, Rob, who’s nineteen and just finishedhis first year of college, says this is becausewhen I was a baby and our mom used to takeme out in my carriage, people would alwaysstop her and say, “What a cute baby boy!” eventhough I was wearing pink and I had a PebblesFlintstone hairstyle (a tuft of hair sticking upon the top of my head and tied with a bright-colored ribbon).Earrings are fun. My jewelry box is filledwith all sorts of different styles. Some days I2like wearing tiny hoops. Other days I likewearing earrings that are long and dangling.Sometimes I’ll just go simple and wear goldstuds. My mom has a fabulous earring collec-tion and sometimes she’ll let me borrow a pair,but only if I ask permission. Sneaking into herjewelry box is not allowed. That’s because herearrings are made of real gold and silver anddiamonds while mine are all pretty much cos-tume jewelry.When I was little, my mom used to braidmy hair in pigtails. Some days she’d give me aponytail. But whatever hairstyle she gave me,she always used silk ribbons and cute barrettesand hair clips. My hair is still long and I lovestyling it in different ways. No short-and-sassyhairstyle for me! My hair reaches past myshoulders to the middle of my back and thecolor is chestnut brown, although sometimes,like during the summer, if I’m out in the sun fora long time, highlights will appear. My bestfriend, Caitlyn, is always telling me she wouldkill to have my hair. I don’t know what she’scomplaining about. Her hair is super curly and3a gorgeous red color. Not carrot red but a richauburn. Like in shampoo ads in magazines. Butshe hates the color and is always trying tostraighten the curls out of her hair.Caitlyn and I have been best friends sincekindergarten. On the first day of school, weboth brought our Cabbage Patch Kids toschool for show-and-tell. The dolls were identi-cal and we decided that they were long-lost sis-ters and it was up to us to make sure theystayed in touch.Caitlyn practically lives at my house andwhen we’re not hanging out together, we’reeither on the phone or instant messaging whenwe’re online. We tell each other everythingalthough there’s a secret I’ve been keepingfrom her.It’s not that I don’t want to tell her mysecret, but I can’t. I’ve been told that part of thejob I’ve just taken is keeping my identity asecret.I know this all sounds mysterious and con-fusing, but it really isn’t. And there’s a perfectlylogical explanation.4This September I’ll be a freshman at NorthMarshall High School and I’ve been picked toinherit the job of being the anonymous fresh-man advice columnist, Dear Daisy, for the highschool’s website. Daisy has been around forever.I think she was even giving out advice whenmy parents were both freshmen there! Beforewebsites existed, she had her own column inthe school’s newspaper. Every year a newfreshman takes over as Daisy, writing the col-umn and dispensing advice.Working on my junior high’s newspaper,writing and editing articles, is what got me thejob of Dear Daisy. I know the importance ofextracurricular activities. Colleges look for thatkind of stuff in addition to good grades, so it’snever too early to start participating.My guidance counselor, who I met when Iwent to pick up my class schedule in June, wasthe one who told me about the Dear Daisyposition. He thought I would be good at it, buthe also told me that there were five other girlswho were just as qualified as I was to take overthe column. If I was interested in becoming5Dear Daisy, then I’d have to submit a samplecolumn and after all the columns were com-pared, a decision would be made
Readicide: How Schools Are Killing Reading and What You Can Do About It - Original PDF
نویسندگان: خلاصه: Every year, those who publish dictionaries are faced with a central question:which emerging words should be added to the new editions? Because somewords have longer life expectancies than others, these decisions are not takenlightly. To make it into a dictionary, a new word must not only show evidencethat it has been around a few years but also that it demonstrates some indicationof staying power. With these criteria in mind, the editors at Merriam-Websterhave chosen a number of new entries for the Merriam-Webster’s CollegiateDictionary, eleventh edition (2006). Recognizing that new words can tell us a bitabout our culture, here are five of my favorites:drama queen: noun, a person given to often excessively emotionalperformances or reactionsgastric bypass: noun, a surgical bypass operation that typicallyinvolves reducing the size of the stomach and reconnecting the smallerstomach to bypass the first portion of the small intestine so as torestrict food intake and reduce caloric absorption in cases of severeobesity

The New Lawyer's Handbook: 101 Things They Don't Teach You in Law School - PDF
نویسندگان: خلاصه: I went to law school right out of college. thankfully, Ihad led a sheltered existence up to that point. my parentswere happily married. my siblings were happily married.my friends were happily single. I was young and incred-ibly naïve. although I had told people since the fifth gradethat I wanted to be a lawyer, I had never even stepped footinside a law office until a part-time job during my senioryear of college.maybe it sounds crazy, but I enjoyed law school—well,most of it anyway. I liked the people, I liked my professors,and I liked the classes. But even at law school, I was shel-tered. I had little understanding of the practical implicationsof entering a profession where conflict is everywhere andthe seven deadly sins make a daily appearance.
I Told You So - PDF
نویسندگان: خلاصه: Told You So was completed at the end of July 2008. This book is acollection of columns from magazines, essays translated from early-century Bloggerean, and material written especially for this compila-tion. After I sent the document file of my book to my editor just bywarily pressing Send, I made a big flourish of checking off the last dayof my six-month writing schedule. I cleaned off my desk, filed twotrees’ worth of hard-copy rewrites, and turned my full attention towriting for my summer show in Provincetown.For more than twenty years I have performed in July and Augustin Provincetown. I write something new every day, especially if theweather is bad; I ride my bike down to the club and try the lines outat night. My audience knows that a lot of the material is being work-shopped for the show I will take on the road in the fall. They knowbecause generally I tell them.Some weeks a brilliant three pages of newly minted material be-comes an aside after only three shows. But other times a throwawayline gets a surprising response and over a few performances grows toa brand-new ten minutes. My audiences like being part of the process.They often talk to me after a show: “When you said that, I thoughtyou were going to go this way,” as if the show were on MapQuest, butthen they finish with the perfect punch line that had eluded me. SinceI have joke dyslexia, they kindly point out when I have reversed setupand punch line altogether. Or they tell me their stories. I take notes. Ipromise them royalties.My partner of twenty years has said to me after almost every showshe has seen, “Well, that was too long, but you need to do more po-litical stuff.” Over the years, and because of the world, I have becomemore political. Actually I am a full-blown junkie. My shows reflectthat. On the Provincetown entertainment menu of drag shows, pianobars, Broadway adaptations, theater, and comedy, I am the entréeknown as “that political one.”In the past, doing a lot of political material for people on theirprecious one- or two-week vacation in a resort town could be dicey.They have been at the beach all day reading trashy beach books orboogie boarding. They have not kept up. Some nights I felt that I wasanchoring a news show, not so much doing a comedy show. Instead oflaughter, I would hear, “I wish she had this on PowerPoint.”The summer of 2008 was like nothing I had ever witnessed. Itwas not just because critical mass had been reached in the possessionof personal handheld devices. Nor was it because the town mothersand fathers had finally gotten some decent radio transmitters andfewer people had to stand out in parking lots screaming into theircell phones, “I can’t hear you!” That summer Wi-Fi was the preferredguesthouse amenity. More than a private bath. No one wanted off thegrid. No one wanted to miss anything. Even on vacation.Would the Hillary supporters get over themselves and make thechange to Obama? Could Obama really beat McCain? The town sleptfitfully, waiting for a text message about Obama’s choice for vice presi-dent. Would he pick Hillary? In the line at the Grand Union, strang-ers would say, “Can’t wait to hear what you have to say about Palin.”Increasingly panicked mass e-mails from California warned of thepassage of Prop Hate, the anti-gay-marriage ballot initiative. Every-one bemoaned high gas prices. Bear Stearns Week trumped the funof Bear Week. International tourists crowded town during CarnivalWeek. Some shops accepted euros. In one ominous sign, the storecalled Don’t Panic was shuttered.When your situation room is a resort town in August, it is difficultto convey the seriousness of some developments to vacationers. It isalso perhaps cruel. In one late August show I joked about George W.,back stateside from the Chinese Olympics, which had been broughtto us by our own credit card debt. With not one little toenail left onhis moral footprint, and still president-erect from cruising the Olym-pic volleyball babes and hectoring China on its human rights abuses,our spectator in chief excoriated Russia for its preemptive strike onGeorgia. You could practically hear the world snorting, or maybe itwas me
Light (Stop Faking It! Finally Understanding Science So You Can Teach It series) (Robertson, William C. Stop Faking It!,) - PDF
نویسندگان: خلاصه: Back when I was in college, there was a course titled Physics for Poets. At aschool where I taught physics, the same kind of course was referred to by thestudents as Football Physics. The theory behind having courses like these was thatpoets and/or football players, or basically anyone who wasn’t a science geek, neededsome kind of watered-down course because most of the people taking the coursewere—and this was generally true—SCARED TO DEATH OF SCIENCE.In many years of working in education, I have found that the vast majorityof elementary school teachers, parents who home school their kids, and parentswho just want to help their kids with science homework fall into this category.Lots of “education experts” tell teachers they can solve this problem by justasking the right questions and having the kids investigate science ideas on theirown. These experts say you don’t need to understand the science concepts. Inother words, they’re telling you to fake it! Well, faking it doesn’t work when itcomes to teaching anything, so why should it work with science? Like it or not,you have to understand a subject before you can help kids with it. Ever triedteaching someone a foreign language without knowing the language?The whole point of the Stop Faking It! series of books is to help you under-stand basic science concepts and to put to rest the myth that you can’t under-stand science because it’s too hard. If you haven’t tried other ways of learningscience concepts, such as looking through a college textbook, or subscribing toScientific American, or reading the incorrect and oversimplified science in anelementary school text, please feel free to do so and then pick up this book. Ifyou find those other methods more enjoyable, then you really are a science geekand you ought to give this book to one of us normal folks. Just a joke, okay?
