Este blog trata basicamente de ideias, se possível inteligentes, para pessoas inteligentes. Ele também se ocupa de ideias aplicadas à política, em especial à política econômica. Ele constitui uma tentativa de manter um pensamento crítico e independente sobre livros, sobre questões culturais em geral, focando numa discussão bem informada sobre temas de relações internacionais e de política externa do Brasil.

Voce pode estar admirando o proximo presidente, nao necessariamente do Brasil...

Bem, sem exageros, mas certos primatas estão mais propensos a aceitar certas fatalidades darwinianas do que quase a metade dos republicanos (americanos, of course, embora eu não descartaria o Brasil nessa involução...).

The Grand Old Primate Party?

Pew survey released yesterday on the public’s view of evolution shows Republicans growing more skeptical of Darwin’s findings, with only 43 percent now endorsing the theory — a drop of 11 points since 2009. Most Democrats are steady believers, with 67 percent in favor, a rise of three points. What all this means for social issue politicking in the new year remains to be seen. But the net effect is a remarkable 24-point evolution credibility gap between the two parties, more than double the 10-point gap of four years earlier.
Overall, the Pew Research Center poll, with a 3-point margin of error either way, found 60 percent in the survey of 1,983 adults agreed that “humans and other living things have evolved over time.” In contrast, 33 percent thought these life forms “existed in their present form since the beginning of time.”

Among believers in evolution, 24 percent held that “a supreme being guided the evolution of living things for the purpose of creating humans and other life in the form it exists today.” Thirty-two percent of evolutionists think it is “due to natural processes such as natural selection.” The phrase natural selection was crafted by Darwin in summarizing his laborious research findings that have come to be accepted as the scientific consensus. The poll did not quote Darwin’s punchier view that “Man is descended from a hairy, tailed quadruped.”

The GOP’s Darwinism


Has the Republican big tent evolved into a house of worship?
For several years, the two major parties have been moving gradually toward opposite poles: Democrats growing more liberal and secular, Republicans becoming more conservative and religious. But a survey out this week shows just how far and how fast the GOP has gone toward becoming a collection of older, white, evangelical Christians defined as much by religion as by politics.

The nonpartisan Pew Research Center recently released the results of an extensive poll done in 2013 on Americans’ views of evolution. Like other polls, it shows that overall views are stable: Sixty percent believe that humans have evolved over time, the same as said so in 2009.
But within those results, there was a huge shift in the beliefs of Republicans: 48 percent say that humans have existed in our present form from the beginning, compared with 43 percent who say we have evolved, either with or without help from a supreme being. That’s an 11-percentage-point swing from just four years ago, when 54 percent believed in evolution.
Forget climate-change skepticism: Republicans have turned, suddenly and sharply, against Darwin.
How to explain this most unexpected mutation? Given the stability of views on evolution (Gallup polling has found responses essentially the same over the past quarter-century), it’s unlikely that large numbers of Republicans actually changed their beliefs. More likely is that the type of people willing to identify themselves as Republicans increasingly tend to be a narrow group of conservatives who believe in a literal interpretation of the Bible — or partisans who regard evolution as a political question rather than one of science.
The Pew poll also found that the share of Republicans who attend worship services weekly or more is 52 percent, up five points from 2009, and that the proportion who self-identify as conservative is 71 percent, up six percentage points from 2009. The party remains overwhelmingly white, at 86 percent, and the number of those ages 50 to 64 and 65 and older climbed seven points and two points, respectively.
Not all of these changes are statistically significant, but they are consistent with other findings. For example, an analysis of exit polls from the early Republican primaries in 2012 by Ralph Reed’s Faith and Freedom Coalition found that more than 50 percent of participants were evangelical Christians, a record high, up from 44 percent in 2008.
This continues a long-term trend in which both parties are shrinking into smaller entities at opposite extremes. The gap on social issues between Democrats and Republicans (and independents who lean toward one party or the other) has nearly doubled over the past quarter-century.
Republicans are by far the more ideologically homogenous of the two (seven in 10 are conservative vs. fewer than four in 10 Democrats who are liberal). Because Republicans were already about as religious as they could get, most of the growing gap in recent years has come from Democrats becoming more secular: The share of Democrats who say they never doubt the existence of God has dropped 11 percentage points over the past quarter-century, to 77 percent, while the proportion of Republicans who have no doubt is 92 percent vs. 91 percent 25 years earlier.
That’s what makes the evolution survey extraordinary: The Republican Party is achieving the seemingly impossible feat of becoming even more theological. Democrats and independents haven’t moved much in their views, while Republicans took a sharp turn toward fundamentalism. “The increasing gap isn’t surprising,” says Alan Cooperman, my former Post colleague who is now director of religion research at Pew. “What’s surprising is it’s the Republicans shifting, not the Democrats.”
As a matter of political Darwinism, the Republicans’ mutation is not likely to help the GOP’s survival. As the country overall becomes more racially diverse and more secular, Republicans are resolutely white and increasingly devout. If current trends persist, it will be only a couple of decades before they join the dodo and the saber-toothed tiger.
But give Republicans credit for this: They don’t just doubt the theory of evolution; they’re out to prove it wrong. If they believed in the survival of the fittest, they’d be expanding their racial and ideological diversity. Instead, they’re trying to demonstrate that devotion to God can trump the Darwinian rules of politics.
Keep them in your prayers.

A eterna luta entre o homem e a natureza...

Os ecologistas ingênuos, que são os novos malthusianos, acreditam que a natureza sempre está certa, e o homem errado. Não é bem assim.
A natureza é neutra, em relação a valores e sentimentos, sendo no mais das vezes "cruel", no sentido darwiniano da palavra.
Pois bem: este sabonete antimalária, criada por estudantes africanos é uma grande notícia.
Depois de seu lançamento comercial, em 2015, o homem vai vencer o mosquito por alguns anos mais.
Como previa Darwin, em algum momento, uma nova espécie de mosquito vai superar a barreira.
A luta continua, camaradas...

Produto repele o mosquito pelo cheiro e já ganhou prêmio

Uma dupla de estudantes africanos criou um sabonete capaz de repelir o mosquito causador da malária. O produto, feito a base de ervas e ingredientes naturais, já rendeu a Moctar Dembele e Gerard Niyondiko um prêmio de U$ 25.000, em abril deste ano, pela "Global Social Venture Competition", uma competição mundial promovida pela Universidade de Berkeley, na Califórnia.

Os dois são alunos do Instituto Internacional de Água e Engenharia Ambiental, em Ouagadougou, capital do Burkina Faso, na África. Como informou Niyondiko ao site da CNN, o sabão, apelidado de "Fasoap", deixa um perfume na pele que repele os mosquitos.

Outro detalhe importante é que a água residual de quem toma banho com o sabonete contem substâncias que impedem o desenvolvimento das larvas de mosquitos. E esse aspecto pode trazer resultados significativos, já que o problema do saneamento na África é uma das causas da proliferação de vetores de malária.

De acordo com Niyondiko, o objetivo é que o produto possa atender a uma parcela significativa da população da África, que não tem acesso aos produtos convencionais industrializados, como cremes e spray, devido aos custos. "Pensamos em um sabonete repelente e larvicida que estará acessível para a maioria da população, uma vez que o sabão é um produto a base de ingredientes regionais", disse Niyondiko ao site.

Por ora, os estudantes ainda estão trabalhando na otimização do produto. A expectativa é que ele chegue ao mercado em 2015.

A Frase da Semana - Darwin

Uma para refletir...


It is not the strongest of the species that survive, nor the most intelligent, but the ones most responsive to change.
