Have You Ever Tried to Sell a Diamond? - Edward Jay Epstein

Have You Ever Tried to Sell a Diamond? - Edward Jay Epstein
The diamond invention—the creation of the idea that diamonds are rare and valuable, and are essential signs of esteem—is a relatively recent development in the history of the diamond trade. Until the late nineteenth century, diamonds were found only in a few riverbeds in India and in the jungles of Brazil, and the entire world production of gem diamonds amounted to a few pounds a year. In 1870, however, huge diamond mines were discovered near the Orange River, in South Africa, where diamonds were soon being scooped out by the ton. Suddenly, the market was deluged with diamonds. The major investors in the diamond mines realized that they had no alternative but to merge their interests into a single entity that would be powerful enough to control production and perpetuate the illusion of scarcity of diamonds. De Beers proved to be the most successful cartel arrangement in the annals of modern commerce. In their subsequent investigation of the American diamond market, the staff of N. N.

Photographer Captures Bizarre Reality Of Toy Production In 'Real Toy Story' Dig into your old toy chest and you're bound to find an adorable bounty of baby dolls, teddy bears and the occasional rubber ducky. So, if you don't want to forever taint your memories of these darling childhood mementos, we recommend you look away now. Photographer Michael Wolf's series "Real Toy Story" delves inside Hong Kong's toy making factories, exposing the mass production and consumption embedded in the lives of your cuddliest childhood companions. Wolf, a German-born artist who has long called Hong Kong his home, examines the bizarre production sites that manufacture, in massive quantities, the cute creatures that children around the globe grow to love. There is something extremely unsettling about the overflowing boxes of baby heads or Barbie limbs in all their pastel-colored glory, recalling the kind of nightmares that crept into our elementary school consciousness. "Real Toy Story" is currently on view at Shanghai's K11 Art Space until February 10, 2014.

How Casinos Enable Gambling Addicts On the morning of Monday, August 13, 2012, Scott Stevens loaded a brown hunting bag into his Jeep Grand Cherokee, then went to the master bedroom, where he hugged Stacy, his wife of 23 years. “I love you,” he told her. Stacy thought that her husband was off to a job interview followed by an appointment with his therapist. Instead, he drove the 22 miles from their home in Steubenville, Ohio, to the Mountaineer Casino, just outside New Cumberland, West Virginia. It didn’t. Stevens, 52, left the casino and wrote a five-page letter to Stacy. He wrote that he was “crying like a baby” as he thought about how much he loved her and their three daughters. He placed the letter and the check in an envelope, drove to the Steubenville post office, and mailed it. Stevens had a request: “Please ask the company to continue to pay my daughters’ college tuition.” Gurbst said he would pass along the request. Then Stevens told Gurbst that he was going to kill himself. “What? He next called J. He paused.

Zastosowanie technik rozciągających w zmniejszaniu ryzyka kontuzji u biegaczy - część teoretyczna | TreningBiegacza.pl Częste wykonywanie tej samej czynności ruchów przeciążeniowych powodujących ból. U biegaczy rzadko dochodzi do strukturalnego uszkodzenia mięśni lub więzadeł. Istotnym jest, iż ukierunkowany trening biegowy wykonywany jednostronnie angażuje do pracy i wzmacnia poszczególne grupy mięśniowej jaką jest bieg prowadzi niejednokrotnie do powstawania stanów przeciążeniowych powodujących ból. Ponadto na zasadzie hamowania wtórnego (reciprocal inhibition), za pośrednictwem ośrodkowego układu nerwowego, może dochodzić do jednoczesnego osłabienia antagonistycznych partii mięśni. Mięśnie, które na przeciążenia reagują osłabieniem oraz zmniejszeniem napięcia zaliczane są do grupy mięśni fazowych. mięśnie prostujące staw kolanowy (mięsień czworoboczny z wyjątkiem mięśnia prostego uda), mięśnie grzbietowo zginające stopę (mięsień piszczelowy przedni i mięśnie strzałkowe), mięśnie pośladkowe, mięśnie brzucha (skośne, prosty i poprzeczny) [Janda 1984, Rakowski 2002, 2001, Stodolny 1999].

How Poverty Taxes the Brain - Emily Badger Human mental bandwidth is finite. You’ve probably experienced this before (though maybe not in those terms): When you’re lost in concentration trying to solve a problem like a broken computer, you’re more likely to neglect other tasks, things like remembering to take the dog for a walk, or picking your kid up from school. This is why people who use cell phones behind the wheel actually perform worse as drivers. We only have so much cognitive capacity to spread around. This understanding of the brain’s bandwidth could fundamentally change the way we think about poverty. In a series of experiments run by researchers at Princeton, Harvard, and the University of Warwick, low-income people who were primed to think about financial problems performed poorly on a series of cognition tests, saddled with a mental load that was the equivalent of losing an entire night’s sleep. This explains, for example, why poor people who aren’t good with money might also struggle to be good parents.

Touched by the Goddess | Articles | Inference: International Review of Science Srinivasa Ramanujan, a self-taught Indian mathematician, compiled during his short life a vast number of deep results spanning analysis, number theory, and modular forms. His achievements rank among those of the greatest mathematicians. The Man Who Knew Infinity is a film about Ramanujan’s remarkable life. The film is based on the biography of the same name by Robert Kanigel, published in 1991.1 Unlike the book, which provides a complete and accurate account of Ramanujan’s life, the film focuses primarily on his time at Cambridge University between 1914 and 1919. The film explores Ramanujan’s work, his relationship with the mathematician G. Although The Man Who Knew Infinity recasts a number of events for dramatic effect, Ramanujan’s life is sufficiently fascinating and intriguing that dramatization is largely unnecessary. His Life Before examining the film in more detail, a brief biographical sketch may be helpful for readers unfamiliar with the subject. The Dramatization and x3+y3=z3+w3

Speech perception Speech perception is the process by which the sounds of language are heard, interpreted and understood. The study of speech perception is closely linked to the fields of phonetics and in linguistics and cognitive psychology and perception in psychology. Research in speech perception seeks to understand how human listeners recognize speech sounds and use this information to understand spoken language. Speech perception research has applications in building computer systems that can recognize speech, in improving speech recognition for hearing- and language-impaired listeners, and in foreign-language teaching. Basics[edit] Acoustic cues[edit] Figure 1: Spectrograms of syllables "dee" (top), "dah" (middle), and "doo" (bottom) showing how the onset formant transitions that define perceptually the consonant [d] differ depending on the identity of the following vowel. The speech sound signal contains a number of acoustic cues that are used in speech perception. Lack of invariance[edit]

Top 10 Subtler Forms of Discrimination Humans While society has not completely discarded racism, sexism and homophobia, at least there’s some public awareness of those issues; other forms of discrimination occur every day and are recognized only by the victims. While we praise our open-mindedness on the ‘big’ issues, could we still be harboring unfair—and perhaps unconscious—prejudices against friends and neighbors? Submitted for your approval are 10 Subtler Forms of Discrimination, and it might open your eyes a bit. Remember, it’s okay to hate people: just do it one son of a bitch at a time. NOTE: I’m not the subtlest of human beings. Bias against bald people started early. The 20th century’s youth-obsessed culture viewed baldness as old age incarnate, and fueled a billion dollar hair care and restoration industry. But, there is hope. So bald men can be sexy now. We could be going faster, but we’re headed (groan) in the right direction. So having hair solves all your problems, right? Think again. That’s not happening.
