Using Indexes
An index can help you quickly locate one or more particular observations
that you want to read. An index is an optional file that you can create for
a SAS data set in order to specify the location of observations based on
values of one or more key variables. Indexes can provide direct access to
observations in SAS data sets to
* yield faster access to small subsets of observations for WHERE
processing
* return observations in sorted order for BY processing

URGENT CARE就是介于家庭医生和医院的急诊室之间的一个看病的地方，它一般不需要
预约，是WALK IN，可以处理一些不是那么生命攸关的但却又让你觉得需要马上解决的
一些身体状况。比如哮喘，食物过敏，感冒，发烧，脚崴了， 呕吐，肚子痛，腹泻，
头疼，需要找家庭医生但是正好是周末或者晚上了，家庭医生不开门，头晕，小伤口需
要缝合，腰扭了，需要输液，吊盐水。父母来探亲没有保险，糖尿病，高血压。和急诊
室一样，
URGENT CARE可以马上当天就能看到医生，但是URGENT CARE的收费比急诊室便宜的多。
比如都是抽血，急诊室的收费标准和URGENT CARE的收费标准是不一样的，同样的服务，
URGENT CARE收费大概只有急诊室的25%。
那你就会问，为什么URGENT CARE会存在，因为现在急诊室的等待时间太长，很多病人
根本不需要去急诊室，
但是他们不知道URGENT CARE的存在，还是跑去了急诊室，结果就导致了急诊室的等待

标 题: 抑郁症有妄想表现吗？
发信站: BBS 未名空间站 (Wed Jan 21 14:54:12 2015, 美东)
张纯如精神障碍的正式诊断是抑郁症。根据美国精神病诊断权威标准DSM-5（附件1），
抑郁症是没有妄想表现的。也就是说，如果一个人被诊断为抑郁症，就不应该有妄想表
现。如果一个人有妄想表现，就不应该诊断为抑郁症。
那么确诊为抑郁症的病人是否可以出现妄想呢？回答是肯定的。但是，当一个抑郁症病
人出现妄想症状，原来的“抑郁症”就不再适用于病人。这种情况下就要改变诊断为“
精神病性抑郁症”。这种病人往往同时会出现幻觉症状。相应的治疗和保护措施也要作
出改变。相关学术依据见附件2。
有些人说张纯如有精神病。所谓的日本右翼极端势力对她不断发出暴力威胁其实是她的
妄想。起码从医生给她的正式诊断来看，张纯如没有妄想症状。

targetting is around 20 to 30 km. This can be improved to 2 to 3 km with
improved algorithm. OTH radar can work with the recon satellites to provide

发信站: BBS 未名空间站 (Mon Feb 1 13:38:17 2010, 美东)
不受祝福的婚姻多了，suck it up！
至于同性和乱伦的关系，人家说的根本不是法律能不能修改成允许前者禁止后者。人家
说的是，反对限制同性婚姻的微薄理由同样适用于反对限制包括乱伦在内的许多异类“
婚姻”，这是法律范畴的问题，是个很严肃的问题，直接关系到这个问题应该用粗暴的
法律手段来解决，还是让社会自己去解决。
至今为止，未见哪怕一个自私的gay和其好心但********的支持者们说出为什么同性婚
姻不能限制，但乱伦能够限制。

发帖数: 19713 | 45 A surprising new study says that nearly one in four Caribbean men today
describe themselves as bisexual, according to the Antigua Observer. The
findings are from the regionwide Caribbean Men’s Internet Survey, which has
been widely touted as the largest sampling of Caribbean men ever done. It
included 2,560 men throughout 33 territories in the region.
“We have a fair population in the Caribbean that identify as bisexual.
Across the entire sample … about 20 to 23 per cent say they are bisexual,”

WASHINGTON – For the third consecutive week, the U.S. Supreme Court has not
revealed its intentions on the Proposition 8 and Defense of Marriage Act (
DOMA) cases that are before them.
The nation’s high court observed the federal holiday on Monday, when the
justices announce what cases they will review and which ones they will
decline. Because of the holiday, they held announcements until toda... 阅读全帖 |

By Paul Harris
Last updated at 10:07 AM on 12th November 2010
He was 3ft tall in his shiny black shoes and he wore his great-uncle’s
medals with pride as he stood to attention in the rain.
Jonny Osborne, seven, symbolised the face of a new generation yesterday as
he marched shoulder to shoulder with servicemen and women to honour those
killed by war.
But three miles across London from the Armistice Day cere... 阅读全帖 |

You have to hand it to Barack Obama. He has unmasked in the most
thoroughgoing way the despotic propensities of the administrative
entitlements state and of the Democratic Party. And now he has done
something similar to the hierarchy of the American Catholic Church. At the
prospect that institutions associated with the Catholic Church would be
required to offer to their employees health insurance covering contraception
and abortifacients, the bishops, priests,... 阅读全帖 |

Before we get any further into this story, I have to warn you that this is
not satire. That having been said, Buzzfeed’s Zeke Miller perpetrated one
of the worst attempts at guilt by association ever made. Miller attempted to
intimate that Mitt Romney is a racist because his motorcade drove past
private property that had a Confederate flag flying on it as he campaigned
in Virginia.
You read that right. All Romney did was sit in a car that drove past a

Obama invites hundreds of foreign 'election observers' to monitor electoral
process
By Rick Moran
Banana Republics around the world are being invited to send representatives
to the US to monitor polling places on election day.
Just think how much about voter fraud we can learn from them!
President Obama has invited the foreigners ostensibly to make sure that all
the illegal aliens, non citizens, felons, and dead people who want to vote,
will get to cast their ballot.
