The First Successful Demonstration Of Brain-To-Brain Communication In Humans. Cockatoos Learn To Make Tools By Watching Their Friends. Baumol's cost disease. Baumol's cost disease (also known as the Baumol Effect) is a phenomenon described by William J. Baumol and William G. Bowen in the 1960s.[1] It involves a rise of salaries in jobs that have experienced no increase of labor productivity in response to rising salaries in other jobs which did experience such labor productivity growth. This seemingly goes against the theory in classical economics that wages are closely tied to labor productivity changes. The rise of wages in jobs without productivity gains is caused by the requirement to compete for employees with jobs that did experience gains and hence can naturally pay higher salaries, just as classical economics predicts.

Thomas Piketty's Capital in the 21st Century. To sum up: modern growth, which is based on the growth of productivity and the diffusion of knowledge, has made it possible to avoid the apocalypse predicted by Marx and to balance the process of capital accumulation.

Thomas Piketty's Capital in the 21st Century

But it has not altered the deep structures of capital -- or at any rate has not truly reduced the macroeconomic importance of capital relative to labor. I must now examine whether the same is true for inequality in the distribution of income and wealth. How much has the structure of inequality with respect to both labor and capital actually changed since the nineteenth century? How simple ideas lead to scientific discoveries - Adam Savage.

Green York University, Toronto, Ontario (Return to Classics index) Is Wine Bullshit? A Lafite Rothschild Bordeaux sells for a minimum of around $500 a bottle, while humble brands like Charles Shaw and Franzia sell for as little as $2.

Is Wine Bullshit?

But as far as “wine economists” are concerned, the level of correlation between the price of a bottle of wine and its quality is low or nonexistent. In a number of damning studies, they suggest that wine is not just poorly priced, but that the different tastes we describe in wine may all be in our heads. A 2008 paper in The Journal of Wine Economics, for example, found that when consumers are unaware of a wine’s price, they “on average enjoy more expensive wines slightly less [than cheap ones].” Cognitive bias. Some cognitive biases are presumably adaptive.

Cognitive bias

Cognitive biases may lead to more effective actions in a given context.[7] Furthermore, cognitive biases enable faster decisions when timeliness is more valuable than accuracy, as illustrated in heuristics.[8] Other cognitive biases are a "by-product" of human processing limitations,[9] resulting from a lack of appropriate mental mechanisms (bounded rationality), or simply from a limited capacity for information processing.[10] A continually evolving list of cognitive biases has been identified over the last six decades of research on human judgment and decision-making in cognitive science, social psychology, and behavioral economics. Cognitive biases are important to study because "systematic errors" highlight the "psychological processes that underlie perception and judgement" (Tversky & Kahneman,1999, p. 582).

Overview[edit] Johari window. The Johari window is a technique created in 1955 by two American psychologists, Joseph Luft (1916–2014) and Harrington Ingham (1914–1995),[1] used to help people better understand their relationship with self and others.

Johari window

It is used primarily in self-help groups and corporate settings as a heuristic exercise. When performing the exercise, subjects are given a list of 58 adjectives and pick five or six that they feel describe their own personality. Peers of the subject are then given the same list, and each pick five or six adjectives that describe the subject. These adjectives are then mapped onto a grid.[2] Charles Handy calls this concept the Johari House with four rooms. World War II Did Not End the Great Depression - Art Carden. [This article originally appeared in the June 2009 issue of the Freeman as "The Great Depression and World War II.

World War II Did Not End the Great Depression - Art Carden

" An MP3 audio file of this article, narrated by Keith Hocker, is available for download.] The current economic climate has a lot of people talking about the Great Depression. In particular, it has been said by people of divergent political views (George Will and Paul Krugman, for example) that World War II ended the decade-long economic nightmare. Examining this claim is worthwhile because it has implications for whether government intervention generally — and in connection with war specifically — are good for the economy. Further, this examination will help us understand how policy changes alter incentives. In Depression, War, and Cold War, Robert Higgs divides the Great Depression into three phases. How to Read Body Language to Reveal the Underlying Truth in Almost Any Situation.

Hilarious Experiment On Monkeys. New study says American families are overwhelmed by clutter, rarely eat together, and are generally stressed out about it all. Tell me about it. That sums up Boston parents’ reaction to new research by UCLA-affiliated social scientists concluding that American families are overwhelmed by clutter, too busy to go in their own backyards, rarely eat dinner together even though they claim family meals as a goal, and can’t park their cars in the garage because they’re crammed with non-vehicular stuff.

The team of anthropologists and archeologists spent four years studying 32 middle-class Los Angeles families in their natural habitat — their toy-littered homes — and came to conclusions so grim that the lead researcher used the word “disheartening” to describe the situation we have gotten ourselves into. At first glance, the just-published, 171-page “Life at Home in the Twenty-First Century” looks like a coffee table book. Euro 2012: les tirs au but ne sont pas une loterie. «Roulette russe» ou «loterie»: si vous entendez ces mots à la télévision pendant un des sept derniers matches de l'Euro, c'est sans doute que, comme cela est déjà arrivé à treize reprises depuis 1976, il se termine par une séance de tirs au but.

Euro 2012: les tirs au but ne sont pas une loterie

«Loterie»? En se fondant sur l'analyse des quelques centaines de tirs au but tirés en Coupe du monde, à l'Euro ou en Ligue des champions, des chercheurs essaient de démontrer le contraire depuis une quinzaine d'années à coup d'indicateurs statistiques, et mettent parfois leur savoir au service des équipes.

A bit more background. If you are in the United States, you probably remember participating in the Decennial Census in 2010. These forms are kept confidential for 72 years—roughly an average American’s life span. But this same rule means that today (actually, a couple of days ago), the 1940 Census results became public information. The good folks at the National Archives have scanned all of these census forms, and put them all online. Perry-Castañeda Library Map Collection - UT Library Online.

The God issue: New science of religion

In a special series of articles we lay out a new vision that resets the terms of the debate In our enlightened world, god is still everywhere. In the UK, arguments rage over "militant atheism" and the place of religion in public life. In the US, religion is again taking centre stage in the presidential election. Perhaps that is because we have been looking at god the wrong way. Like it or not, religious belief is ingrained into human nature. Viewing religion this way opens up new territory in the battle between science and religion, not least that religion is much more likely to persist than science.

Of course, the truth or otherwise of religion is not a closed book to science: the existence of a deity can be treated as a scientific hypothesis. 10 biggest puzzles of human evolution.
