This essay traces seven stages in the American controversy over abortion between 1960 and 1980. The argument moved from a professional debate to a public dispute marked first by narratives, then successively by the ideographs “life,” “discrimination,” and “choice,” and then to a normalization and stalemate in which the public consensus reflects values and interests from both sides of the conflict. 相似文献

Students and parents rely on Web-based tools to navigate the college-choice process, yet little research has been done to understand this environment. While this shift has made the process easier to navigate for some, we contend that the move will grow an already large digital divide in the USA. We use Hossler and Gallagher's college-choice framework to examine the substance and function of three college-access Web portals. Our findings suggest these tools are likely to serve many students well in the process, but may exacerbate the digital divide with consequences for low-income students. 相似文献

Miniature replicas modeled after the Great Pyramid of Giza are believed to concentrate geoelectromagnetic energy within their
cavities and hence act as antistressors in humans and animals. Although there are not many reports of adverse effects of ‘overexposure’
in the pyramid, subjects have claimed to feel uneasy after certain duration of staying in the pyramid. The present study was
aimed to analyze the effects of prolonged pyramid exposure on plasma cortisol level, markers of oxidative damage and antioxidant
defense in erythrocytes of adult female Wistar rats. Rats were divided into three groups, normal controls (NC, n=6) that were
maintained under standard laboratory conditions in their home cages, pyramid exposed group-2 (PE-2, n=6) & pyramid exposed
group-4 (PE-4, n=6) where the rats were housed under the pyramid for 6 hours/day for 2 weeks and 4 weeks respectively. Plasma
cortisol and erythrocyte TBARS levels were significantly lower in both PE-2 and PE-4 rats and erythrocyte GSH levels and GSH-Px
activity were significantly higher in them as compared to the NC rats. There was no significant difference in the results
for these parameters between the PE-2 and PE-4 rats except for erythrocyte GSH-Px activity which was significantly more in
the PE-2 rats than in the PE-4 rats. Although these results don’t confirm any adverse effects of prolonged exposure in pyramids,
they indicate a possibility of such adverse effects. 相似文献
