Estudar online
Rápidos e gratuitos: os cursos MOOCs vão substituir os MBAs?
Quando Luis Ochoa tentou dar um salto na sua carreira, deixando de ser analista de investimentos para virar estrategista corporativo, ele resolveu não fazer o óbvio neste mercado, que é obter um Master of Business Administration, ou MBA.
Em vez disso, ele fez alguns cursos gratuitos de estratégia e contabilidade financeira no site Coursera, um dos maiores provedores de Massive Open Online Courses (cursos online abertos em massa, ou "MOOCs" na sigla em inglês)."Eu ganhei uma base com esses cursos que me ajudou na transição para virar estrategista corporativo", diz o nova-iorquino de 29 anos. "Agora não pretendo fazer um MBA porque já estou onde queria chegar."
Como ele, um número cada vez maior de pessoas está buscando MOOCs como forma de se promover na carreira - sem necessidade de investir o mesmo tempo e dinheiro exigido por um título universitário tradicional.
O desafio para quem opta por essa modalidade é convencer seus empregadores e o mercado de trabalho sobre o valor destes cursos online.
"Nós ainda recebemos perguntas de várias empresas sobre o quão bons são os MOOCs, mas estamos percebendo que cada vez mais as empresas estão considerando esta modalidade para habilitar seus funcionários", diz Sebastian Thrun, da Udacity, da Califórnia, que oferece esse tipo de curso.

Primeira guerra mundial - uma vista contrafatual
11 Intriguing Ways World War I Could Have Turned Out Differently
Expand
The First World War may have have featured static battlefields and attritional strategies, but that doesn't mean the course of events from 1914 to 1918 couldn't have unfolded differently. Here are 11 events that could have changed the outcome of the Great War.

Listed in roughly chronological order.
1. No Russian Mobilization in 1914
Russian troops prepare for war. The Great War/BBC
Had it not been for the Russian mobilization of July 1914, the Great War might not have ever happened. By rushing to the defense of its Slavic ally, Serbia, Russia set German plans into motion. Earlier, Germany had issued a "blank cheque" to Austria-Hungary, promising to come to its aid should Russia interfere with its efforts to tame Serbia. But after relations between Russia and Germany soured, and as Russian troops scrambled along the Austrian border, Germany believed it had no choice to but to roll out its Schlieffen Plan — a strategy wherein France, an ally of Russia, was to be defeated prior to launching an all-out assault on Russia; the idea was to prevent a war on two fronts, which is precisely what ended up happening anyway.
Russia mobilized for several reasons. It was looking to re-assert itself after an embarrassing defeat to Japan in 1905. It was also the era of pan-Slavism, in which dreams of independent slavic states fueled aggressive foreign policies. But from a purely strategic perspective, there was no critical reason for Russia to come to Serbia's defense. The Tsar's actions turned a regional Balkan conflict into a global conflagration. But perhaps intentionally, it thwarted the plans of Austria-Hungary to expand its aging Empire into a tripartite state — the never-achieved Austro-Hungarian-Balkan League.

Decálogo de Bertrand Russell
Decálogo de Bertrand Russell:
1. Não tenhas certeza absoluta de nada.
2. Não consideres que valha a pena proceder escondendo evidências, pois as evidências inevitavelmente virão à luz.
3. Nunca tentes desencorajar o pensamento, pois com certeza tu terás sucesso....
4. Quando encontrares oposição, mesmo que seja de teu cônjuge ou de tuas crianças, esforça-te para superá-la pelo argumento, e não pela autoridade, pois uma vitória que dependente da autoridade é irreal e ilusória.
5. Não tenhas respeito pela autoridade dos outros, pois há sempre autoridades contrárias a serem achadas.
6. Não uses o poder para suprimir opiniões que consideres perniciosas, pois as opiniões irão suprimir-te.
7. Não tenhas medo de possuir opiniões excêntricas, pois todas as opiniões hoje aceitas foram um dia consideradas excêntricas.
8. Encontra mais prazer em desacordo inteligente do que em concordância passiva, pois, se valorizas a inteligência como deverias, o primeiro será um acordo mais profundo que a segunda.
9. Sê escrupulosamente verdadeiro, mesmo que a verdade seja inconveniente, pois será mais inconveniente se tentares escondê-la.
10. Não tenhas inveja daqueles que vivem num paraíso dos tolos, pois apenas um tolo o consideraria um paraíso.

História, histórias - o caso dos Estado Unidos
How Drunkards, Whores & 'The Immoral' Shaped the Nation (w/ Thaddeus Russell)
Thaddeus Russell is the author of A Renegade History of the United States. He takes a brash, maybe even borderline blasphemous look at the American bourgeoisie and puritans of the past. How did weekends come to be, and how did the mafia, brothel madams, minorities, homosexuals, and others considered "deviant" by the ruling puritanical culture help shape the nation? And is it possible to criticize the suffrage movement and even Martin Luther King Jr.?! Cenk Uygur hashes it all out in this probing interview with Thaddeus Russell.Mais

Challenging Society's View on Drugs - Dr. Carl Hart
Malcolm Fleschner (Executive Producer for The Point) interviews Dr. Carl Hart (Professor of Psychiatry and psychology at Columbia University) on his new book, "High Price." The book challenges what our perception of drugs, and whether it's actually appropriate to blame poverty and societal ills on addiction.Are current drug policies failing? According to Dr. Hart's book, yes. He explains why with his landmark, yet controversial studies of race, poverty,, and drugs as well as the relationship between drugs and pleasure, choice, and motivation, both in the brain and in society. Hart relates his own story that started in a tough Miami neighborhood and resulted in a career as a neuroscientist and Columbia University's first tenured African American professor in the sciences.

Aquecimento global
A temperatura média das águas frias dos oceanos parou de aumentar desde 2005, o que traz novos questionamentos aos cientistas sobre por que o aquecimento global parece ter diminuído nos últimos anos, apesar do aumento das emissões de gases causadores de efeito estufa.
Uma das principais hipóteses apresentadas até agora para explicar este paradoxo é que o calor acumulado pelos oceanos desceu a grandes profundidades.
Os cientistas da Nasa, do Laboratório de Propulsão a Jato (JPL) em Pasadena (Califórnia, oeste), analisaram a temperatura dos oceanos entre 2005 e 2013, com base em medições realizadas com satélites e diretamente em águas oceânicas, com 3.000 boias distribuídas por todo o mundo.
"Descobriram que sob os 1.995 metros praticamente não houve mudanças de temperatura durante este período", destacaram no trabalho publicado na revista britânica Nature.
Apesar disso, "o nível dos oceanos continuou subindo", principalmente devido ao degelo no Polo Norte e na Groenlândia, destacou Josh Willis, da missão JPL e co-autor da pesquisa.
No entanto, o especialista considera o fenômeno inexplicável não põe em dúvida a realidade do aquecimento global.
Comer carne faz bem
Food For Thought: Meat-Based Diet Made Us Smarter
Our earliest ancestors ate their food raw — fruit, leaves, maybe some nuts. When they ventured down onto land, they added things like underground tubers, roots and berries.
It wasn't a very high-calorie diet, so to get the energy you needed, you had to eat a lot and have a big gut to digest it all. But having a big gut has its drawbacks.
"You can't have a large brain and big guts at the same time," explains Leslie Aiello, an anthropologist and director of the Wenner-Gren Foundation in New York City, which funds research on evolution. Digestion, she says, was the energy-hog of our primate ancestor's body. The brain was the poor stepsister who got the leftovers.
Until, that is, we discovered meat.

Socialismo e libealismo
"Socialists and liberals agree in
seeing the ultimate goal of economic policy as attainment of a state of society
assuring the greatest happiness for the greatest number. Welfare for all, the
greatest possible welfare for the greatest possible number – that is the goal
of both liberalism and socialism, even though this may now and then be not only
misunderstood but even disputed. Both reject all ascetic ideals that want to
restrain people to frugality and preach renunciation and flight from life; both
strive for social wealth. Only over the way of reaching this ultimate goal of
economic policy do their view disagree ….”

Mises: Nation, Staat und Wirtschaft 1919

Dormir
Your Ancestors Didn’t Sleep Like You – Are We Doing It Wrong?
Evidence continues to emerge, both scientific and historical, suggesting that the way in which the majority of us currently sleep may not actually be good for us.
In 2001, historian Roger Ekirch of Virginia Tech published a paper that included over 15 years of research. It revealed an overwhelming amount of historical evidence that humans used to in fact sleep in two different chunks. (1)
In 2005, he published a book titled “At Day’s Close: Night in Times Past,” that included more than 500 references to a disjointed sleeping pattern. It included diaries, medical books, literature and more taken from various sources which include Homer’s Odyssey all the way to modern tribes in Nigeria and more.
