1.9日晚杀鸡失败，继续磨刀(新增阅读回忆) - ChaseDream

The following appeared as part of an article in a magazine devoted to regional life.

“Corporations should look to the city of Helios when seeking new business opportunities or a new location. Even in the recent recession, Helios’s unemployment rate was lower than the regional average. It is the industrial center of the region, and historically it has provided more than its share of the region’s manufacturing jobs. In addition, Helios is attempting to expand its economic base by attracting companies that focus on research and development of innovative technologies.”

“Because of recent advancements in business and technology, the overall quality of life in most societies has never been better than at the present time.”

jj: 1990 生产
0.8m，每年增加constant，到2000年11年共生产了14.3m，问每年增加了多少
先以为是增加constant rate，算没有答案，后来才发现是constant quantity。

当作等比数列算简直太麻烦了，我最后还是按照等差的算，Range=1.0m

1p说以前的carbon14的检测方法有限制，只能检测14000-25000的古代stuffs

2p提出一种新的方法，好像叫做Accelarator mass，说这种方法能检测25000-40000的物品，而且只需要很小的样品。

3p举了个north-west asian迁移到北美的例子，经鉴定他们不可能是XXXXX年前迁移过去的，后来说了一些时间证据。

这篇要特别注意那些时间，有道题就是问下面那些东西可以要用Accelartor mass的方法来测定（就是在时间上面做文章的）

不是很难，网上查一查 working memory, sptail cortex, MRI 什么的，大概了解一下就行了

和jj上写的差不多，就是经济学家说可以用经济价值还衡量很多东西。

好像说经济学家提到可以用resort hotel衡量coast shore的price value.

问题中有一道就是问为什么提到resort hotel，我选的好像是提出了一个例子说明经济学家的说法。

今天失利的同志们，不要难过，太阳依旧从东方升起。会因为某一个人而不转的。所以收拾一下心情，继续努力～

嗯，多谢。就把它当模考了

对，要抱着那种：老美，你拿走我的250刀吧，大爷我赏你的～

此话有理，中国传统节日就要到了，就当替我儿子给老美的压岁钱。

噢,哥们儿...咱两抱头痛哭一场吧!!!

然后擦干眼泪重新再来!!!!!!!

哭啥，这次考不好认栽，以后一定灭了这只鸡!

努力！

对滴，熊猫兄。。下次你用你的珍贵的大身体压扁那只鸡，今天你只是砍了一刀，它还活着，，所以还是飞跑了～留下了你几根羽毛～

你的图片就是熊猫啊，就像小F的图片是加菲一样，所以你是熊猫兄～：）

你给我们确定了一个JJ就是拔了几根羽毛啊。。说明还是有点收获的。。

add oil .猫兄～。猫妹今天晚上据说考试呢。。都是一家人啊。。一个早上，一个晚上，呵呵

working memory那题说什么了？机经上说了跟没说一样，呵呵。跪求。

Working memory is the process of maintaining a limited
amount of information in an active representation for a
brief period of time so that it is available for use. There-
fore, by definition, working memory includes those
processes that enable us to hold in our `mind's eye' the
contents of our conscious awareness, even in the absence
of sensory input. Thus, the study of working memory
provides a framework for investigating the neural system
underlying our awareness of stimuli, memories and
knowledge that are no longer tied to perceptual events.
Although the neural system responsible for working
memory is known to include a large number of brain
regions, there is abundant evidence from neurophysio-
logical and lesion studies in monkeys that prefrontal
cortex is a critical component (Fuster 1990; Goldman-
Rakic 1990). Recent brain-imaging studies, using
positron emission tomography (PET) and functional
magnetic resonance imaging (fMRI), have also impli-
cated the human prefrontal cortex in working memory
. However, there remain questions and some
dispute about the functional organization of the human
prefrontal cortex and its exact role in working memory.
Here we summarize the evidence for working memory-
related activity within human prefrontal cortex.We then
present evidence for domain speci¢city within frontal
cortex for object working memory as opposed to spatial
visual working memory. We also review evidence
suggesting an additional dimension of domain speci¢city
for object working memory based on whether the type of
representation is analytic or image-like. In addition, we
discuss evidence suggesting a third dimension for the
specialization of working memory function in prefrontal
cortex that distinguishes regions important for the main-
tenance of the contents held in working memory from
regions important for the manipulation of those contents.
Finally, we consider the relationship of prefrontal areas
important for working memory, both to posterior visual
processing areas and to prefrontal areas associated with
long-term memory.
