Assume 2% of the 7% Asians are Chinese, then 6m * 0.02 = 0.12m or 120,000
Assume 1/3 Asians are Chinese, then 6m * 0.07/3 = 0.14m or 140,000
If use US average asian population figure and 1/3 Asians are Chinese, then

发帖数: 15854 | 9 我觉得preset的目的是改变色彩的风格，而不应该是导致偏色。举个不恰当的例子，合理
的运用preset，就像运用一种数学变换，可以把一个正态分布的population变成其他
的分布，但是却并不改变他的median，mean，也就是说整个色彩空间还在某个范围之内
，只不过分布方式重新排列了。如果不恰当的运用preset，就好象把整个population移
动了，median 和mean都偏了。
当然，同样的preset，就像同样的数学变换，作用在不同的population上面，会有不同
的结果。如果原来的population是广泛的分布，fully diversified，那么变换的结果
就是重新改变分布，而不容易使之发生偏移。但是如果原来的population太过集中和单
调，那么变换的结果很可能就是让整体发生偏移。 |

原因在于什么地方呢，在于他们的基因的功能不能incompatible了。
让我们假设一下他们共同的祖先的genotype是aabb，在某一个时候，这个祖先的

文/江南独立记者
（邮箱：d*******[email protected]，欢迎对此事关注的人士提供线索、建议或帮助）
在美国洛杉矶华人聚集区之一的蒙特利公园市，一项眼科健康调查（CHES：CHINESE
AMERICAN EYE STUDY）正在华人社区中展开。
奇怪的眼科检查
在美国定居多年的华人王丁（化名）参与了这项调查，现在他开始为这个调查感到百思
不得其解：“说检查眼睛为何要获取我的血样和DNA？”。
这一切要从9月说起，王丁当时接到CHES工作人员的电话，征询他是否愿意参加这项眼
科健康调查计划。60多岁的王丁眼睛不太好，当他看到这样的免费服务，而且又是当地
一家有名的眼科医院检测，他满口答应下来。
在当地，眼科检查至少要收取65美元的挂号费，如果再加一些眼科治疗，费用可能在几
百美元甚至上千美元，王丁说：“CHES不仅不收费，而且还承诺25美元的车马费。”对
很多像王丁这样的普通华人来说，这是一个诱惑。
王丁在电话里答应检查后，调查组的工作人员来到王丁的家里，对王丁的年龄、遗传病
史、疾病既往史、赴美时间等详细信息一一记录，这些资料都被输入到工作人员随身携... 阅读全帖 |

"Aging Is a Rich-Country Problem?"
NO.
Indeed, most developing countries are experiencing population aging at
unprecedented rates. Consider Iran. As recently as the late 1970s, the
average Iranian woman had nearly seven children. Today, for reasons not well
understood, she has just 1.74, far below the average 2.1 children needed to
sustain a population over time. Accordingly, between 2010 and 2050, the
share of I... 阅读全帖 |

If China had a population of 300 million, I'd agree with the author's
conclusions. But with a popular 3-4X that number, China has serious
environmental degradation, pollution and resource issues. At this point, "
replacement rate" is irrelevant. The key is how to lower the population
while managing to sustain growth. With her current population, the per
capita income can never rise to developed world levels.
