One amazing study of the impact of cultural memes: Baltimore kids growing up

leave a comment »

Quite an amazing article in the Washington Post by Emily Badger:

BALTIMORE — In the beginning, when they knew just where to find everyone, they pulled the children out of their classrooms.

They sat in any quiet corner of the schools they could claim: the sociologists from Johns Hopkins and, one at a time, the excitable first-graders. Monica Jaundoo, whose parents never made it past the eighth grade. Danté Washington, a boy with a temper and a dad who drank too much. Ed Klein, who came from a poor white part of town where his mother sold cocaine.

They talked with the sociologists about teachers and report cards, about growing up to become rock stars or police officers. For many of the children, this seldom happened in raucous classrooms or overwhelmed homes: a quiet, one-on-one conversation with an adult eager to hear just about them. “I have this special friend,” Jaundoo thought as a 6-year-old, “who’s only talking to me.”

Later, as the children grew and dispersed, some falling out of the school system and others leaving the city behind, the conversations took place in McDonald’s, in public libraries, in living rooms or lock-ups. The children — 790 of them, representative of the Baltimore public school system’s first-grade class in 1982 — grew harder to track as the patterns among them became clearer.

Over time, their lives were constrained — or cushioned — by the circumstances they were born into, by the employment and education prospects of their parents, by the addictions or job contacts that would become their economic inheritance. Johns Hopkins researchers Karl Alexander and Doris Entwisle watched as less than half of the group graduated high school on time. Before they turned 18, 40 percent of the black girls from low-income homes had given birth to their own babies. At the time of the final interviews, when the children were now adults of 28, more than 10 percent of the black men in the study were incarcerated. Twenty-six of the children, among those they could find at last count, were no longer living.

A mere 4 percent of the first-graders Alexander and Entwisle had classified as the “urban disadvantaged” had by the end of the study completed the college degree that’s become more valuable than ever in the modern economy. A related reality: Just 33 of 314 had left the low-income socioeconomic status of their parents for the middle class by age 28.

Today, the “kids” — as Alexander still calls them — are 37 or 38. Alexander, now 68, retired from Johns Hopkins this summer just as the final, encompassing book from the 25-year study was published. . .

Continue reading.

And by all means, read the whole thing: it’s not just about these kids, it’s about the cultural landscape of the city: who lives on the good cultural clusters, who on the marginal, and the devastating effects of a bad cultural cluster.

But of course it can be interrupted in a generation were there the will. But those who occupied privileged niches will be loath to change.

The window of opportunity to fix climate change is closing quickly

leave a comment »

Justin Gillis has a sobering report in the NY Times, a report that I fear will do nothing to stir Congress and governments to take action. He writes:

Runaway growth in the emission of greenhouse gases is swamping all political efforts to deal with the problem, raising the risk of “severe, pervasive and irreversible impacts” over the coming decades, according to a draft of a major new United Nations report.

Global warming is already cutting grain production by several percentage points, the report found, and that could grow much worse if emissions continue unchecked. Higher seas, devastating heat waves, torrential rain and other climate extremes are also being felt around the world as a result of human emissions, the draft report said, and those problems are likely to intensify unless the gases are brought under control.

The world may already be nearing a temperature at which the loss of the vast ice sheet covering Greenland would become inevitable, the report said. The actual melting would then take centuries, but it would be unstoppable and could result in a sea level rise of 23 feet, with additional increases from other sources like melting Antarctic ice, potentially flooding the world’s major cities.

“Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reduction in snow and ice, and in global mean-sea-level rise; and it is extremely likely to have been the dominant cause of the observed warming since the mid-20th century,” the draft report said. “The risk of abrupt and irreversible change increases as the magnitude of the warming increases.”

The report was drafted by the Intergovernmental Panel on Climate Change, a body of scientists and other experts appointed by the United Nations that periodically reviews and summarizes climate research. It is not final and could change substantially before release.

Continue reading. Given the crop failures we’re likely to see as global warming intensifies (drought, extreme rainfall, and so on), I would expect food wars to erupt within a few years. Indeed, the Arab Spring uprising seems to have been prompted in part because of food shortages that caused increased prices.

Large Dams Just Aren’t Worth the Cost

leave a comment »

And what do you bet that, even if this were absolutely established, people would still continue to build large dams? I bet you anything that they would.

Jacques Leslie writes in the NY Times:

THAYER SCUDDER, the world’s leading authority on the impact of dams on poor people, has changed his mind about dams.

A frequent consultant on large dam projects, Mr. Scudder held out hope through most of his 58-year career that the poverty relief delivered by a properly constructed and managed dam would outweigh the social and environmental damage it caused. Now, at age 84, he has concluded that large dams not only aren’t worth their cost, but that many currently under construction “will have disastrous environmental and socio-economic consequences,” as he wrote in a recent email.

Mr. Scudder, an emeritus anthropology professor at the California Institute of Technology, describes his disillusionment with dams as gradual. He was a dam proponent when he began his first research project in 1956, documenting the impact of forced resettlement on 57,000 Tonga people in the Gwembe Valley of present-day Zambia and Zimbabwe. Construction of the Kariba Dam, which relied on what was then the largest loan in the World Bank’s history, required the Tonga to move from their ancestral homes along the Zambezi River to infertile land downstream. Mr. Scudder has been tracking their disintegration ever since.

Once cohesive and self-sufficient, the Tonga are troubled by intermittent hunger, rampant alcoholism and astronomical unemployment. Desperate for income, some have resorted to illegal drug cultivation and smuggling, elephant poaching, pimping and prostitution. Villagers still lack electricity.

Mr. Scudder’s most recent stint as a consultant, on the Nam Theun 2 Dam in Laos, delivered his final disappointment. He and two fellow advisers supported the project because it required the dam’s funders to carry out programs that would leave people displaced by the dam in better shape than before the project started. But the dam was finished in 2010, and the programs’ goals remain unmet. Meanwhile, the dam’s three owners are considering turning over all responsibilities to the Laotian government — “too soon,” Mr. Scudder said in an interview. “The government wants to build 60 dams over the next 20 or 30 years, and at the moment it doesn’t have the capacity to deal with environmental and social impacts for any single one of them. . . .

Diesel fuel used in fracking: Goodbye drinking water….

leave a comment »

The biggest lawbreakers in this country are large corporations, and they seem immune to prosecution. Naveena Sadasivam reports for ProPublica:

A new report charges that several oil and gas companies have been illegally using diesel fuel in their hydraulic fracturing operations, and then doctoring records to hide violations of the federal Safe Drinking Water Act.

The report, published this week by the Environmental Integrity Project, found that between 2010 and July 2014 at least 351 wells were fracked by 33 different companies using diesel fuels without a permit. The Integrity Project, an environmental organization based in Washington, D.C., said it used the industry-backed database, FracFocus, to identify violations and to determine the records had been retroactively amended by the companies to erase the evidence.

The Safe Drinking Water Act requires drilling companies to obtain permits when they intend to use diesel fuel in their fracking operations. As well, the companies are obligated to notify nearby landowners of their activity, report the chemical and physical characteristics of the fluids used, conduct water quality tests before and after drilling, and test the integrity of well structures to ensure they can withstand high injection pressures. Diesel fuel contains a high concentration of carcinogenic chemicals including benzene, toluene, ethylbenzene and xylene, and they disperse easily in groundwater.

FracFocus is an online registry that allows companies to list the chemicals they use during fracking. At least 10 states, including Texas, Colorado and Pennsylvania, mandate the use of the website for such disclosures.

The report asserts that the industry data shows that the companies admitted using diesel without the proper permits. The Integrity Project’s analysis, the report said, then showed that in some 30 percent of those cases, the companies later removed the information about their diesel use from the database. . .

Childhood Lead Exposure Causes a Lot More Than Just a Rise in Violent Crime

leave a comment »

Kevin Drum has a good post, with a graph of the data, on the influence of childhood lead exposure on subsequent teen-age pregnancies. From the post:

Jessica Wolpaw Reyes has a new paper out that investigates the link between childhood lead exposure and violent crime. Unsurprisingly, since her previous research has shown a strong link, she finds a strong link again. But she also finds something else: a strong link between lead and teen pregnancy.

This is not a brand new finding. Rick Nevin’s very first paper about lead and crimewas actually about both crime and teen pregnancy, and he found strong correlations for both at the national level. Reyes, however, goes a step further. It turns out that different states adopted unleaded gasoline at different rates, which allows Reyes to conduct a natural experiment. If lead exposure really does cause higher rates of teen pregnancy, then you’d expect states with the lowest levels of leaded gasoline to also have the lowest levels of teen pregnancy 15 years later. And guess what? They do. The chart on the right shows the correlation between gasoline lead exposure and later rates of teen pregnancy, and it’s very strong. Stronger even than the correlation with violent crime.

None of this should come as a surprise. The neurological basis for the lead-crime theory suggests that childhood lead exposure affects parts of the brain that have to do with judgment, impulse control, and executive functions. This means that lead exposure is likely to be associated not just with violent crime, but with juvenile misbehavior, drug use, teen pregnancy, and other risky behaviors. And that turns out to be the case. Reyes finds correlations with behavioral problems starting at a young age; teen pregnancy; and violent crime rates among older children.

. . .We were poisoning our children with a well-known neurotoxin, and this toxin lowered their IQs, made them into fidgety kids, wrecked their educations, and then turned them into juvenile delinquents, teen mothers, and violent criminals. When we got rid of the toxin, all of these problems magically started to decline.

Read the whole thing and contemplate the graph.

“The Libertarian Fantasy”

leave a comment »

Paul Krugman once more points out some fundamental flaws in the libertarian position (that the free market can solve all problems):

n the latest Times Magazine, Robert Draper profiled youngish libertarians — roughly speaking, people who combine free-market economics with permissive social views — and asked whether we might be heading for a “libertarian moment.” Well, probably not. Polling suggests that young Americans tend, if anything, to be more supportive of the case for a bigger government than their elders. But I’d like to ask a different question: Is libertarian economics at all realistic?

The answer is no. And the reason can be summed up in one word: phosphorus.

As you’ve probably heard, the City of Toledo recently warned its residents not to drink the water. Why? Contamination from toxic algae blooms in Lake Erie, largely caused by the runoff of phosphorus from farms.

When I read about that, it rang a bell. Last week many Republican heavy hitters spoke at a conference sponsored by the blog Red State — and I remembered an antigovernment rant a few years back from Erick Erickson, the blog’s founder. Mr. Erickson suggested that oppressive government regulation had reached the point where citizens might want to “march down to their state legislator’s house, pull him outside, and beat him to a bloody pulp.” And the source of his rage? A ban on phosphates in dishwasher detergent. After all, why would government officials want to do such a thing?

An aside: The states bordering Lake Erie banned or sharply limited phosphates in detergent long ago, temporarily bringing the lake back from the brink. But farming has so far evaded effective controls, so the lake is dying again, and it will take more government intervention to save it.

The point is that before you rage against unwarranted government interference in your life, you might want to ask why the government is interfering. Often — not always, of course, but far more often than the free-market faithful would have you believe — there is, in fact, a good reason for the government to get involved. Pollution controls are the simplest example, but not unique.

Smart libertarians have always realized that there are problems free markets alone can’t solve — but their alternatives to government tend to be implausible. For example, . . .

Interesting as a take on Israel

leave a comment »

That parents can transmit their own trauma to their offspring. Article here. If true, one can see both some potential contributors to Israel’s use of arms and occupation, and also how this generation’s conflicts will similarly shape the Palestinians, who pretty clearly on the suffering side of this war, in loss of family members as a rough metric. Their next generation will show the trauma.
