美国与北约对苏联的输油钢管禁运

A Revision to the U.S. Southwest Archaeomagnetic Master Curve

Recently, two problems have been recognized with the United States Southwest archaeomagnetic master curve (Eighmy, 1991; LaBelle & Eighmy, 1997; Sternberg, 1989). One of these problems, the damping problem, is inherent to the moving window method of curve construction proposed by Sternberg (1989). The other is due to the fact that the small number of independently dated virtual geomagnetic pole determinations available for the period between 900–1100 are not representative of secular variation during this period. The analyses presented here confirm the existence of these two problems and suggest that they distort the curve by less than 1·0° and between 1·0° and 2·0° respectively. Based on these findings, a new curve is proposed for the U.S. Southwest.     

Earmarks and Elections to the U.S. House of Representatives

Popular treatments of earmarks abound with allegations that members of Congress use them to aid their reelection campaigns, but the academic literature has yet to examine whether earmarking influences elections. To begin to fill this void, we search for relationships between earmarking and several facets of electoral competition and outcomes in the 2008 and 2010 House elections. There are three principal findings. First, in both election years, active earmarkers faced weaker primary election competition than other members. Second, in 2008 there was a positive correlation between earmarking and campaign receipts. Third, both of these correlations exist only among Democrats. These findings suggest that earmarks critics might be correct in charging that members, particularly Democrats, benefit from the earmarks they place into spending bills.
