Airways in Mali, Niger, and Guinea carry current market
data to farmers and traders in remote areas. Local staff visit markets;
record prices for crops and livestock on solar-powered laptops; and e-mail
the information by radio waves to regional offices where the data are
compiled for broadcast. In Mali, where
John Staatz and
colleagues began the project, knowing when and where to sell for the best
price helped millet farmers increase their income.
Gas
and particulate emissions from animal feeding operations (AFOs) can cause
unpleasant odors and even health problems for workers and nearby residents.
Wendy
Powers collects baseline emission data from AFOs and models the
impact of factors like geography, climate, ventilation in the animal
housing, growth cycle of the animals, and diet. She found that changing
animal diets can control some emissions at the source.
Guofang Li
is evaluating the results when e-learning pedagogy is blended with
face-to-face education in a bilingual environment. Teachers in
Chinese/English schools in Shanghai are using interactive multimedia social
studies and literature modules and other electronic technologies for their
students in grades 3-5. Such e-learning may help create a culturally and
linguistically authentic environment, even in contexts lacking direct
contact with the target language.
About 6 percent of children have a variant of the IL1RN
gene that makes them more than four times as likely to develop asthma if
their mothers smoked during pregnancy.
Susan Ewart and
colleagues in the UK found the genetic link to the kids’ environment through
long-term studies of more than 900 children. Normally, IL1RN, the
Interleukin-1 receptor antagonist, provides anti-inflammatory activity; the
variant may reduce that effect.
Genetic
researchers study the distribution of genetic variations among racial/ethnic
groups, hoping to explain racial/ethnic health disparities, but the practice
is controversial. In open-ended interviews with genetic scientists,
Linda Hunt
found that the racial/ethnic variables they use are poorly defined and their
methods of classification are arbitrary and implicit. Such socially
constructed concepts may serve administrative or political purposes but lack
sufficient rigor to be used as key variables in biological research. |
