Murders fall by 8.6% in South Africa

Post n°6 pubblicato il 09 Settembre 2010 da nmdipahozy
 

PRETORIA (AFP) – Violent crime declined last year in South Africa, the police minister said Thursday, with murders down 8.6 percent to under 17,000, in one of the world's most violent countries.

"The murder figure fell below the 17,000 mark, compared to 26,877 in the 1995-1996 fiscal year," police minister Nathi Mthethwa told a news conference.

"We are really encouraged in the significant decline in the murder rate," he said.

The crime statistics report covered the year ending in March, and showed violent crime generally was on the decline, with attempted murders down by 6.1 percent and sexual offences down by 4.4 percent, he said.

The report did not cover the period of the football World Cup, which was held June 11-July 11.

Montana's Stillwater buying Toronto metals company

Post n°5 pubblicato il 08 Settembre 2010 da nmdipahozy
 

BILLINGS, Mont. – Stillwater Mining Co. is buying Marathon PGM Corp. for $118 million to gain control of the Canadian company's Ontario precious metals reserve and other properties, the companies announced Tuesday.

The deal reflects the resurgence of precious metals market after a price collapse two years ago sent the industry into retreat and forced Stillwater to cut about 300 workers. If it is approved by regulators, Stillwater plans to develop a $400 million pit mine near Marathon, Ontario over the next three years, chief executive Frank McAllister said.

The mine would allow the Columbus-based company to increase its platinum and palladium production by 40 percent. That's equal to about 1,250 pounds annually of the metals used in jewelry, in industrial processes and to make catalytic converters for vehicles — a market that's been booming in developing countries such as China and India.

Stillwater, with its two mines in southern Montana's Beartooth Mountains, is the only U.S. producer of platinum group metals.

Marathon is headquartered in Toronto. It has been developing the Marathon PGM-Cu project near the town of Marathon, Ontario, since 2004.

The deal is expected to be completed by the end of November pending regulatory and shareholder approvals. It comes amid strong demand for platinum group metals and the depletion of overseas inventories, McAllister said.

"The timing of the Marathon transaction is ideal for Stillwater, and it positions the company to benefit from the convergence of these market factors," he said.

For Stillwater, it represents a sharp turnaround from two years ago when the company was laying off workers and temporary idling its East Boulder mine.

In a measure of the company's confidence that the hard times are past, McAllister also said Tuesday that Stillwater was re-evaluating the use of floor and ceiling prices in its contract with Ford Motor Co. that expires this year.

Such contracts have allowed Stillwater to hedge against low metal prices, but they also limited the company's gains when prices were high.

The Marathon mine would operate for at least 12 years based on platinum and palladium reserve estimates of more than 3 million ounces, or about 94 tons.

The reserve also contains an estimated 500 million pounds of copper that will be mined as a byproduct. Sales of copper and small amounts of gold and silver from the site would offset almost all production costs, McAllister said.

Marathon CEO Phillip Walford said Stillwater first approached his company about five years ago to discuss a joint venture or acquisition, but nothing came of those discussions until Stillwater returned in recent months as precious metal prices rebounded.

Increasing demand for catalytic converter materials has helped drive prices higher. Developing countries are setting new environmental regulations to deal with smog caused by soaring automobile ownership rates.

"I don't know a place in the world where you can buy a new vehicle without a catalytic converter in it," Walford said. "The whole worldwide production of platinum and palladium is about 14 million ounces a year. Gold is 100 million ounces a year, so this is pretty rare stuff."

Through its acquisition of Marathon, Stillwater also gains control over a second Ontario project, Geordie Lake, and an emerging platinum resource in Manitoba known as the Bird River property.

Stillwater shares fell 55 cents, or 3.6 percent, to $14.73 on Tuesday.

The company is majority owned by Russian metals-industry giant Norilsk Nickel. In July, Stillwater reported a second-quarter profit of $14.6 million on revenue of $134.9 million. That compared with a profit of $4.6 million in the second quarter of 2009 on revenue of $94.8 million.

Michigan studies show poor childhood diets could lead to chronic ill health, breast cancer

Post n°4 pubblicato il 08 Settembre 2010 da nmdipahozy
 

By Vince Lamb, Examiner.com

Two studies from local universitiesthat poor dietary choicesduring one's school years could result in severe health problems duringadulthood.

One paper, authored by a team of researchers from the University ofMichigan, Michigan State University, and Food & Nutrition DatabaseResearch, Inc., of Okemos, described how school children who consumefoods purchased in vending machines, school stores, and snack bars aremore likely to develop poor diet quality early in life than those whoeat meals provided as part of the United States Department ofAgriculture (USDA) school lunch program or which are packed at home. As a result,these children are more likely to be overweight or obese. Their dietsmay also put them at risk for chronic health problems such as diabetesand coronary artery disease later in life.

Another paper, penned by a pair of Michigan State Universityresearchers came to a more dire conclusion. Girls who eat ahigh-fat diet during puberty, even if they do not become overweight orobese, may be at a greater risk of developing breast cancer later inlife. The implications could drive new cancer prevention efforts.

Together, the two studies demonstrate how poor food choices early inlife could cause health problems later, as well as the importance ofproper nutrition and establishing good dietary choices during childhood.

Eating vending machine food in schools leads to poor health

Inpublished in the September issue of the Journal of School Health,Madhuri Kakarala, Clinical Lecturer of Internal Medicine at theUniversity of Michigan Medical School, Debra R. Keast, President of Food& Nutrition Database Research, Inc., of Okemos, and Sharon Hoerr,Professor of Food Science and Human Nutrition at Michigan StateUniversity, found that 22 percent of students of all ages nationwideconsumed food from vending machines, school stores, snack bars eachschool day. The percentage of students purchasing food from sourcesother than the cafeteria was greatest in high school, where 88 percentof schools had vending machines, compared to 52 percent of middleschools and 16 percent of elementary schools.

Soft drinks accounted for more than two-thirds of beverages offeredin school vending machines and stores. Desserts and fried snacks werethe most commonly consumed vended items among elementary school childrenand beverages other than milk and fruit juice were the most commonlyconsumed items among middle and high school students. Other frequentlyconsumed vended foods included candy, snack chips, crackers, cookies,cakes, and ice cream.

As a consequence of their diets, students who ate food from vendingmachines, school stores, snack bars, and other sources that compete withUSDA School Lunch program offerings consumed significantly more sugarand total calories than the ones who ate food from the cafeteria. Theyalso ate less sodium, dietary fiber, B vitamins, and iron.

In a ,study leader Kakarala said, "Consumption of vended foods and beveragescurrently offered in U.S. schools is detrimental to children's dietquality. Childhood obesity, resulting from poor dietary choices, such asthose found in this study, greatly increases the risk for many chronicdiseases. A healthy school food environment can reduce these dietaryrisks."

Kakarala continued, "Targeted nutrition education to promote theimportance of healthful snacks is further stressed by the ChildNutrition Act-the major federal legislation that determines school foodpolicy and resources. These and other types of school-enforced policiescan be very helpful for children in making smarter eating choicesthroughout the school day."

Based on their findings, the study authors recommended that schooladministrators design guidelines restricting foods and beverages soldthrough vending machines and school stores to those that are rich innutrients but not high in calories. They also suggest that schoolfood-service personnel prepare point-of-service materials and displaysto promote more healthful foods such as fresh fruit, yogurt, low-fatmilk, juice, ansandwiches.

High-fat diets and breast cancer

That a high-fat diet during puberty can increase breast cancer riskmany years later comes from research at Michigan State University'sBreast Cancer and the Environment Research Center, which was establishedin 2003 and funded through 2010 by the National Institute ofEnvironmental Health Sciences and the National Cancer Institute.

Physiology professor Sandra Haslam, director of the center, andRichard Schwartz, microbiology professor and associate dean in theCollege of Natural Science, are now expanding that research with a new,five-year, $2.3 million federal grant. They will use that funding tocontinue their work studying the impact of prenatal-to-adultenvironmental exposures that predispose women to breast cancer as partof the extended nationwide Breast Cancer and the Environment ResearchProgram.

"The pubertal time period is crucial, as this is when the basicframework is created for mammary gland development," Haslam said in ."What we are seeing from preliminary research in animals is that ahigh-fat diet during puberty can lead to the production of inflammatoryproducts in the mammary glands of adults, which can promote cancergrowth."

Since these inflammatory changes first occur during the crucial timeof puberty, a period of intense development and cell division, it canhave effects lasting a lifetime.

To test their findings, Haslam and Schwartz will lead a teamanalyzing two different mouse models of breast cancer and the effects ofhigh-fat diets during puberty. They also will test severalanti-inflammation interventions designed to overcome the negativeeffects of a high-fat diet on inflammation.

Chemicals in Rugs, Cookware May Be Linked to Raised Cholesterol in Teens

Post n°3 pubblicato il 07 Settembre 2010 da nmdipahozy
 
Tag: di me

MONDAY, Sept. 6 (HealthDay News) -- Common chemicals found in everything from non-stick cookware to grease-resistant food packaging appear to be associated with increases in cholesterol levels in adolescents, a new study suggests.

People are exposed to these chemicals -- known as perfluoroalkyl acids (PFAAs) -- in dust, drinking water, non-stain carpets, waterproof fabrics, microwave popcorn bags and a host of other household products.

"This is the first study that takes an in-depth look at an association between these chemicals and health effects in children," said study author Stephanie J. Frisbee, research instructor in the Department of Community Medicine at West Virginia University School of Medicine in Morgantown.

The PFAA compounds in question include perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS).

"We found a positive association between PFOA and PFOS and total [cholesterol] and LDL cholesterol," she said. As the blood levels of these chemical increased, so did cholesterol, Frisbee added.

The American Chemical Council, an industry group, did not respond to repeated attempts by HealthDay to get comment on the findings.

The report is published in the September issue of the Archives of Pediatrics & Adolescent Medicine.

For the study, Frisbee's team looked at cholesterol levels in more than 12,000 children and adolescents who are part of the C8 Health Project. This project resulted from the settlement of a class-action lawsuit against Dupont over thelandfill dumping of chemicals that contaminated groundwater in six water districts in two states near the company's plant in Parkersburg, West Virginia, and exposed residents to levelsof C8 (another name for PFOA) far higher than that of the general population.

Among the participants, the average PFOA concentration was 69.2 nanograms per milliliter and average PFOS concentration was 22.7 nanograms per milliliter.

Among 12- to 19-year-olds, the PFOA concentrations were higher than those seen in the general population, but PFOS concentrations were similar to those seen in samples from the general population, the researchers found.

Increased PFOA levels were associated with increased total cholesterol and LDL, or "bad," cholesterol, and PFOS was associated with increased total cholesterol, LDL cholesterol and HDL, or "good," cholesterol, the researchers said. Neither chemical was associated with an increase in triglyceride levels, they added.

On average, the children with the highest PFOA levels had higher cholesterol, compared with the children with the lowest PFOA levels. In addition, those with the highest PFOS levels had cholesterol that was more than eight points higher than those with the lowest PFOS levels, Frisbee's group found. That translated to an average difference of 8.5 milligrams per deciliter.

Frisbee noted that higher cholesterol levels had also been found in adults who took part in the C8 Health Project and were exposed to these chemicals.

Whether the association between these chemicals and cholesterol is causal isn't known. To find out, further research is needed, Frisbee said.

"We cannot speak at this point -- it would be scientifically inaccurate -- to speak about causality," she said. In addition, the potential harm to these children and teens is still not known, Frisbee added.

However, animal studies have shown that the liver is the organ most affected by perfluoroalkyl acid, and the liver is where cholesterol is made, the researchers noted.

"These are chemicals that do not degrade in the environment," Frisbee added.

Both chemicals are being phased out in the United States of use and being replaced by other compounds. Whether these new chemicals are safe or whether they carry their own set of health problems isn't known, Frisbee said.

"The way the U.S. system works is that you get to use whatever you want until somebody says there is a problem," she said.

One cholesterol expert, Dr. Ronald B. Goldberg, a professor of medicine at the Diabetes Research Institute of the University of Miami Miller School of Medicine, said that the increase in LDL cholesterol levels seen in the study, "can have a small but significant effect on heart disease."

Goldberg noted that the main cause of increasing cholesterol is animal fat in the diet. "On top of that, you have genetic abnormalities that are common," he added.

But the effect of chemical exposure needs more study, Goldberg said. "All you can say now is there is an association, and it doesn't prove that the contaminant is causing the LDL rise," he said.

Red Familiesv. Blue Families

Legal Polarization and the Creation of Culture

by Naomi Cahnand June Carbone Oxford, 304 pp., $29.95

In 1998, Fugees frontwoman and single mother Lauryn Hill scored a hit with her hip-hop ode to her son Zion, in which she described how the people around her had pressured her to abort him: "They said, 'Lauryn baby, use your head' / But instead I chose to use my heart. / Now the joy of my world is in Zion!"

Hill's voice won't be found in Naomi Cahn's and June Carbone's deeply flawed, intermittently important book. In fact, Red Families v. Blue Families contains virtually no voices representing alternatives to the elite lifestyle of contraception, college (and probably postgraduate) education, and late childbearing. The book is replete with numbers, but because it incorporates very little qualitative research-in which the voices behind the numbers might get a chance to explain themselves-it's impossible to gauge the accuracy of Cahn/Carbone's analyses of the reasons behind the American class-based marriage gap.š

Judging by my admittedly limited experience, Red Families offers a sanitized picture of elite family life-ignoring the degree to which shame, and abortion in response to shame, shapes elite young women's choices-and a distorted picture of underclass and lower middle-class family life, explaining class-based differences in out-of-wedlock childbearing and pregnancy as a result of lack of access to contraception, which is one of the very few explanations I think I've literally never heard from any lower-income woman.

Although Cahn/Carbone clearly want to offer solutions to the multiple and conflicting crises in American family structures, solutions which respect and can be accommodated by a wide variety of different communities and world views, they are ultimately unable to articulate or understand any alternative to what they've (somewhat crudely) decided to call the blue family model.

"Blue families," a term which they acknowledge has highly limited relevance to racial minorities who often follow "red family" models while voting Democratic, delay childbearing at least until the late twenties, often well into the thirty- something years. They contracept consistently and effectively, get pricey educations, and have abortion to back them up when even the most controlled birth control fails. (The abortion rates of blue states are higher than those of red states, though that difference does not fully explain the fact that out-of-wedlock childbirth rates are lower in prototypical blue states. If red staters contracepted as effectively as blue staters, and all other factors were held equal as of course they never are, the red states would still have more unwed mothers and fatherless children.) Although they can afford a lot of kids, the blue staters have very few: two, maybe one. Cahn/Carbone characterize this as privileging "investment" in children, quality over quantity.

Red families preach abstinence until marriage but practice divorce and unwed childbearing. They don't abort their children, but neither do they marry for life. They marry early and divorce much more than their blue state counterparts. They're also poorer, for the most part, and their income levels are pretty obviously both cause and symptom of their fractious family structure.

There are many good points to this analysis. Cahn/Carbone note how completely "abstinence until marriage" has been discarded at all levels of American society. It is not possible to address the needs of American families without first acknowledging that almost no one actually lives the way that, for example, the Roman Catholic Church thinks we should.

In their final and best chapter, Cahn/Carbone also offer a passionate call f a radical restructuring in how our economy accommodates parents and parents-to-be. The unionized factory jobs which stereotypically supported a breadwinner-homemaker family, where the spouses married right after high school, have been replaced by service- and-information-economy jobs which require highly specialized education and licensing: fields like cosmetology and medical-information processing. This volatile economy requires a much more flexible structure in which work, family, and education can interweave.š

Red Families is frustratingly vague on how this interweaving and flexibility could actually work-and the authors have a depressingly unimaginative tendency to answer every question with "Let the government do it," as if the regulatory state has been the expert advocate for the needs and interests of the poor-but the book's willingness to call the basic structure of the American economy into question is deeply necessary. Cahn/Carbone point out the places where our economic and governmental structures have not caught up with the needs of contemporary American couples and their children.š

But the many good things in Red Families are obscured by the authors' relentless, unsubtle framing of every question from within a blue-family mindset so deeply internalized that perhaps the authors themselves don't realize what they're doing. They don't want to come across as if they're telling Mississippians to abort more kids so they write this sentence, which opens the sixth chapter: "Contraception is the indispensable element of the blue family paradigm; abortion, in contrast, is the regrettable but necessary fallback." If you can tell the difference between "indispensable" and "necessary," you are a subtler thinker than I am.š

And while they don't want to come across as if they're telling Alabamans what to value, they fail to articulate a worldview in which early childbearing is an accomplishment, a form of contributing to society, and abortion is a tragedy rather than a solution. Coerced and regretted abortions are entirely absent from their discussion, and again, no actual low-income men and women get a chance to describe their reasoning, and their hopes and fears and loves.^Aš

Meanwhile, the authors waste time and page count on simplistic psychologizing of traditionalists vs. modernists and conservatives vs. liberals, in which the righties lack the "flexible" morality, attuned to "context," of their lefty counterparts. I wonder whether self-proclaimed conservatives or liberals are most likely to be nuanced and attuned to context on the issues of torture, the death penalty, and spanking? These pop science descriptions of why people disagree with us are often comforting but rarely illuminating.

Class is the intersection of economic status and culture. It doesn't describe merely income level or purchasing power or "net worth." Cahn/Carbone are trying-genuinely, poignantly trying-to offer solutions to our country's family crises which respect the diversity of our beliefs. But they consistently view poor or nonelite Americans as simply elite Americans without the resources to act on the values they obviously share with the authors. And so they ignore the most important fact about class: It changes the definition of words. "Responsibility," a Red Families motif, is always used to mean postponing childbearing-and not, as it means to many nonelite women, accepting early childbearing and rejecting abortion.

There's a telling aside in the final chapter. Cahn/Carbone describe the 2008 Republican platform on work/family integration and add a sardonic parenthetical remark: "So long as [new regulations have] no negative impact on productivity." This might be the book's sole acknowledgment-and it's a dismissive one-that there may be trade-offs in life. For the rest, we are meant to believe that not merely in the long term, but even in the short, a massive expansion of government regulation and a campaign to get "red staters" to embrace the Pill, will have no adverse consequences. We are asked to believe that there is no tension between the economic and the spiritual. In Red Families the rich man always passes through the needle's eye.

Our family structures are shaped largely by economic pressures-but also, and importantly, by what we find beautiful. How do we recognize love? How do we corral desire, honoring some forms of its expression and restricting others? Our marriage traditions, along with our extended kinship networks, used to offer models beautiful enough to inspire sacrifice. An approach which focuses solely on the economics of sex and procreation can do some good, but-as Red Families unfortunately proves-it can't comprehend the full range of human motives.
