人类D19S40基因座在不同人种中的遗传多态性研究

采用ＰＣＲ技术分析中国汉族、德国人、斯洛伐克人和美国黑人群体Ｄ１９Ｓ４００基因座的遗传多态性及世界三大人种之间的差异。四个群体共调查了６２０人,发现了１１个等位基因,观察到４７种基因型。各群体观察杂合度为：０．７８～０．８８,个人识别机率为：０．９３８５０～０．９６６４。四个群体基因型频率分布符合Ｈａｒｄｙ－Ｗｅｉｎｂｅｒｇ平衡（Ｐ＞０．０５）,三大人种（蒙古人种、高加索人种、美国黑人）之间Ｄ１９Ｓ４００基因座等位基因频率分布存在极显著差异（Ｐ＜０．０１）。结果显示Ｄ１９Ｓ４００基因座在群体遗传学研究和法医学个人识别中有较高应用价值

What Stabilizes State General Fund Expenditures in Downturn Years—Budget Stabilization Fund or General Fund Unreserved Undesignated Balance?

This article strictly defines the budget stabilization fund (BSF) as a counter-cyclical reserve, and with a panel data set examines the effects of BSF and general fund unreserved undesignated balances (UUB) on stabilizing state general fund expenditure during downturns. The article finds that BSFs bolster spending in lean years: each percentage point increase of BSF balance as a percent of general fund expenditure can minimize negative expenditure gap by a quarter percentage point. But the article does not find evidence that UUB is a counter-cyclical fiscal tool, indicating that wide adoption of BSF may have changed the nature and use of UUB.
