鲸鱼那篇找到网上某篇考古,希望对大家有用:
【因纽特人和鲸鱼】
讲因纽特人inuit 和bowhead whale的。结构比较清晰,两段,很长!要耐心!
第一段v1住在极地的人对生存环境很了解,v2有一种方式是当地人(hunter,elders)和专家学者一起来保护北极的环境v3因纽特人在北极的环境问题中有独特的知识,由八个国家组成的北极联合会(arctic council)在处理环境问题上也要参考因纽特人的知识。
第二段,有一种鲸鱼,科学家估计,只有 800头,趋于灭绝,而因纽特人质疑了科学家的方法认为有 7000 头。科学家是认为whale不能长时间在冰盖下游泳,而得出的 800 头的结论。而因纽特人根据自己在北极生活的经验,这种鲸鱼实际上是可以在冰盖下游泳的,而且还会migrate。后来科学家在鲸鱼身上装无线电设备,确定它们可以在冰盖下游泳。证实了因纽特人的经验,因此,因纽特人也不用受保护这种鲸鱼的法律所限制,可以继续捕猎鲸鱼了。
T1:有当地人质疑了科学家哪点,7000vs800
T2:问了第二段的结构是什么,选的是先抽象的介绍了合作的 application,然后用一个real-world 例子来解释这个应用。
T3:问了当地人为什么很 care whale 的数量,定位最后一句话,很隐蔽。答案选了因为和他们可以捕猎的数量相关。
[考古]
"讨论 Inuit 民族捕杀 whale 的习俗是真是假。
第一段在讲说虽然研究者发现 inuit 民族有利用鲸鱼的骨头做住家之类的习惯,他们的很多房子都是鲸鱼骨头做的,不过有些学者认为这些不一定能证明 inuit 民族真的有出海捕鲸鱼,他们可能只是在沙滩上捡鲸鱼的骨头去用,并不一定表明他们捕杀活的鲸鱼。
第二段其实还是很有可能他们捕杀活的鲸鱼的,因为有证据证明, Inuit 有一种工具, 足可以杀掉鲸鱼。而且他们还有一种船,所以他们能够杀鲸鱼,虽然, 现在还没有出土这种工具。还提到说 inuit民族过着善用资源的生活,因为他们居住环境。很不适合人居,然后举反例说当时的欧洲人都可以靠其它的 source survive.(这里有出题)
第三段举跟祭拜仪式有关的,提到一些壁画还是什么, 是有杀鲸鱼的, 但是现在的 Inuit 人已经不会杀鲸鱼了。

2.还有一个一屏多点儿的,关于北极圈内的啥东西被运用到environmental management的文章。第一段讲了这个东西原来是干啥用的,现在开始incorporate with环境和管理blabla,还举了一个国家间组织作为大家合作使用这个的例子(这块儿不是很确定了)。第二段主要是一个例子,说明用于环境管理的,是说1970年scientists认为某种whale只存活800条了要保护,hunters认为这个不对,尤其质疑了科学家的assumption(这个whale只在浅水游动,且migration过程中不吃东西),于是大家用了个什么办法(好像是绑了个什么仪器之类的),最后发现大概有几千头whale,于是hunters被证明是对的。
唉最终我都没懂到底是啥东西的运用....大家注意那个例子吧,例子挺清晰的,后面还考了hunter的主要质疑是什么。还考了主旨题。
In 1977, scientific surveys indicated that bowhead whales (Balaena mysticetus) in the Beaufort Sea were in trouble, with fewer than 1,000 individuals remaining. The International Whaling Commission took action to put a moratorium on native hunts in order to protect the species. Yet local Inuit hunters didn't see what the fuss was about. Their own estimates, gleaned from time and experience, put bowhead numbers at 7,000. The Inuits also disputed western scientists' contentions that whales couldn't swim under offshore ice and that they did not feed during migration. Researchers responded to these criticisms by developing a new survey method to census the population, incorporating Inuit understanding of whale behavior. In 1991, the new survey estimated that bowheads numbered 8,000- an affirmation of the ecological knowledge held by individuals who depended upon the whales for food, fuel, and shelter (Freeman 1995). As indigenous sovereignty and other rights become recognized around the globe, many governments are developing strategies to work with indigenous communities to co-manage land and resources (Colchester 2004). In navigating this often daunting process, a new challenge has arisen: How to accept and incorporate into western science the traditional ecological knowledge and cultural norms that guide how indigenous communities use and manage natural resources.

KEYCONCEPTS
■ When the eyes fix on something, they stilljump imperceptibly in ways that turn out to be essential for seeing.
■ For decades, scientists have debated thepurpose, if any, of these so-called fixational eye movements, the largest ofwhich are called microsaccades.Now the authors have demonstrated that microsaccadesengender visibility when a person’s gaze is fixed and that bigger andfaster microsaccades work best.
■ Microsaccades may also shed light on subliminal thoughts. Recent research suggests thatthe direction of microsaccades is biased toward objects to which people areunconsciously attracted, no matter where they are actually looking. —TheEditors

Bird Song and theProblem of Honest Communication: How is the honesty of animal signalsmaintained when exaggeration and bluff are so tempting?
William A. Searcy andStephen Nowicki
American Scientist
Vol. 96, No. 2(MARCH-APRIL 2008), pp. 114-121
Published by: Sigma Xi, The ScientificResearch Honor Society

Many animals communicateinformation about their fitness through vocalizations directed to potential matesand competitors alike. (In fact, people are no exception.) From an evolutionarystandpoint, however, what preserves the integrity of such messages? Would not exaggerationprovide a competitive advantage? What biologists call signal reliability is nowa central question in animal behavior, and bird song has been a model for studying it for morethan a half century. The authors are investigating signaling in male song sparrows (Melospiza meladia), which use the same songsfor both courtship and aggression.
The Cost of Singing Softly
Given that soft song isindeed the display that most reliably predicts attack in song sparrows, what is tokeep males from cheating in order to appear more aggressive? Again, to answer thisquestion one must take another look at the handicap hypothesis, in which the costsof signals are crucial to enforcing their honesty. Scientists have proposed different types of expenses that could beincurred for aggressive signals, butmost seem unlikely to apply to soft song. Energycosts, for one, are still unlikely because songs in general, and those oflow intensity in particular, take very little energy to produce. The kind of developmental cost discussedearlier for song repertoire size also seems unlikely,because these costs are more likely to apply to signals established over the longterm, rather than signals that change over the short term at will. A thirdpossibility is what is called a ”vulnerability cost,” where the manner in which a signal is producedinherently makes the individual giving it more vulnerable to attack. A vulnerability cost might seem plausible forsoft song if, becauseof its low amplitude, it can only be perceived by a receiver when the singer isclose by, making it an unambiguoussignal of proximity and thus vulnerability. However, because of the way thatsound attenuates with distance, a signal that issoft when it reachesthe receiver could beeither a low-intensity signal produced near the signaler or a high-intensity signalproduced farther away. By contrast, a signal that is loud when it reaches thereceiver is actually less ambiguous in conveying that the signaler is close by.
repertoire (noun) = all the songs, pieces of music, etc. that a performerknows and can perform
at will = If you can do something at will, you can do it anytime you want
attenuate (verb) = to make something smaller, thinner, orweaker
We have argued that soft song is a reliable aggressive signal because it is an unambiguous and costly signalof attention, not of proximityor vulnerability. Soft song is usually producedquite close to the intendedreceiver, so that the receivercan both see and hear the singer. The listener then should be able to discern thevolume at which the song is produced, and because of its low volume, soft song isunlikely to be audible to any other individuals. Thus by singing at low intensitynear a rival, the singer is indicating that its attention is focused solely on thatparticular bird.
Soft songs are alsocostly to the singer because they are unlikely to reach other targets. In the caseof female receivers,the cost could be a diminished proclivity to mate,as we have shown that femalesong sparrows find softsong less attractive than songs sung at a normal broadcast amplitude. The more-significant costof soft song, however, is probably that other male receivers fail to hear a responsefrom the male being challenged, leading neighbors or other potential usurpers to be more likely to intrude on the soft-singer’sterritory.
proclivity (noun) = a natural tendency to do something or tofeel something, often something bad
usurp (verb) = to take somebody’s position and/or powerwithout having the right to do this
A recent study of ours supportsthe idea that soft songis costly because it limits reception to a single intended receiver. In this experiment,we simulated singing interactions between an intruder and a territory owner, inwhich the latter sang softly or at a normal level. First we recorded the territoryowner and mapped his territory; then we captured and held him temporarily. Whilethe owner was held, we placed two loudspeakers on his territory, and staged a virtualinteraction by playing an intruder's song through one speaker and the owner’s songfrom the other. The intruder song was recorded from a male holding a distant territory,and was always played at normal level. In half the trials, the owner’s song wasalso played at normal level, and in the other half the owner’s song was played ata level typical of soft song. The result was that intrusions by other male song sparrows were more common and moreserious when the simulated owner sang soft songs than when he used loud song. Presumably,other males listening to the interaction from off the territory cannot hear theowner when he uses soft song, and thus cannot tell that he is countering the intruder.Thus by using soft song to signal his focused attention to one intruder, the territoryowner sacrifices his ability to ward off other potential intruders.
一共两段,大半瓶,第一段是说雄性的某种鸟会soft sing,然后说这种sing 有的是有效的,有的是无效的(考试的时候没看清逻辑,说的可能有点奇怪/捂脸)。 第二段好像是在找这种softsing 的解释,首先提出了一个energycost(这个词记得很清楚),后来好像否定了这个观点。
然后又提出了一个attack cost(好像是叫这个),说这种sing能帮助雄鸟吸引还是躲避天敌来着(忘了)。最后作者的态度,emmmm,狗主实在没时间去琢磨了,抱歉。
鸟用soft的叫声警示敌人
有一种鸟用soft的叫声来警示敌人?为什么是soft的叫声呢,因为这种警示的行为是有cost的。
V1: (By nabalaxuan)
第一段:一种动物(好像是麻雀) 发出很轻的声音 如何从Natural selection的角度解释,有一个科学家说这涉及到一种cost
第二段:energy cost, 但这个解释不好,因为很轻,不用多少能量
vulnerable cost 这个是指动物发出声音是会把其暴露在predator面前的,所以轻易不会发出这个声音
V2: (By Espange, V23) 考到一个 说什么biologistcost来解释为什么公麻雀在表示要袭击敌人的时候温柔地叫。。。(soft singing )
第一段说提出这个现象 有一个理论
第二段说另外几种解释。。。后来说会被敌人觉得ambiguity就是混淆了 就是麻雀本来是想吓唬敌人表示要袭击了 但是叫得太轻柔了 会被让敌人很迷糊
V3: (By Gem99333) 有一篇讲说公麻雀啊你温柔的叫。
说公麻雀温柔的叫的时候,其实是在预警,马上就要进攻敌人了!然后大家都觉得这个行为过于丧心病狂啊,怎么来解释这种行为呢?然后有一位大师挺身而出表示:这个问题嘛,可以用Biology SignalCost来解释。然后解释了一下这个Cost,但是说实话这句话我看的比较糊涂,但是大致是说如果
第二段呢就开始说,用Biology Cost解释似乎还是有那么一点问题的哎。然后它就分析了一下这个Cost可能是个啥。一方面呢,他可能是个ACost(专有名词失忆了,这一片都没有出题点所以看两眼过吧),这个Cost是讲说,这样叫的时候消耗的能量比较小。但是这种说法不太成立,因为似乎本来消耗的能量就是非常小的。然后看另一方面,他有可能是个B Cost(重点)。《警示:后面的内容很!混!乱!因此不确保回忆准确,大家遇到这篇的话一定要用心读后面的内容,因为有出!题!点!》接着说这个B Cost,狗主理解这个成本说的是释放出“哥们儿我在这儿呢你特么给我小心点”这样的信号,就是说这个信号是要告诉对方自己已经接近了。但是作者认为这个解释也并不合理,因为这样的声音信号经过对手加工后会变得很混沌,就是对方根本无法通过这样的叫声判断出来这只破鸟到底在哪里。同时作者认为,与这样的温柔的叫相比,尖利的叫声更容易让对方确认自己就在附近,因此B Cost的解释也不合理。本文到此戛然而止,让感觉人不知所云。。。
有一个主旨题,失忆一道。另有一道通篇细节题,但重点考察B Cost之后。这里面请大家尤其注意:有一个选项说,作者认为他们温柔的叫声是否是为了把对手吓跑。考场上遇到这道题请务必认真分析,狗主认为不是,但犹豫了一会儿。
V4: (By Bobeyscript)
【P1】 说这种鸟的softsinging is a highly reliable signal of the intention to attack. 生物界里面有很多时候动物都会发出声音来signal potential attack (好像是这样,不太记得了~)但是不是所有signal都是reliable 的。 科学家提出一种假设,就说动物的这种行为存在biological cost——而这种cost使得unreliable的signal 逐渐消失(因为要耗cost,很浪费~),而最终剩下的都只会是reliable 的signal.
【P2】说这种biologicalcost存在的形式有很多种,其中一种不太可能的是“energy cost”(具体名词不记得了,可能是这个吧)。因为softsinging本身就不用耗能太多。比较可能的是“vulnerability cost”.然后就解释说为什么是v cost.
【P3】但是呢,即使有biologicalcost的存在,降低了unreliable的可能性,还是有不准确的地方。然后就举例说明。就说soft singing可能是一只鸟近距离发出的很soft的signal, 也可能是另一只鸟在远处发出很大声的signal.所以没有办法确切地知道发出声音的鸟的具体位置。
V5 (By Spagette, 780) 原文一共两段,第一段讲sparrow的叫声,尤其是那种轻柔的叫声到底是reliable还是unreliable的让研究人员比较困惑。第二段讲研究叫声靠不靠谱时涉及的两种biological costs,一种是energycost,一种是vulnerability cost。考了一个主题题,不记得答案了。考了一个细节题,答案是鸟的叫声大小不总是正确的反应鸟和receiver的距离,答案很确定。
V6 (By 匿名, V38)跟机经有点出入的是:作者对两钟cost的态度都是否定的,就是说这两个都不能解释为什么soft song是reliable的, 之前发的原文上很详细了。因为第二段有个地方说:the vulnerability cost will explan the reliability ifsoft song的接受者(receiver)认为....,但是这个if...不一定成立,因为远处的broad song也会让receiver认为在近处。
有个题问:以下哪种最可能,我选了麻雀soft song之后就开始打架...(因为第一段说soft song是reliable的)其他的选项都不对...
V7 (By alathen) Q1主旨题,
Q2,下面哪个是正确的,
A鸟叫得轻柔是为了节省生物能什么的
B鸟的叫得轻柔但是其实这货想表示aggressive action什么的
V8 (By 819474084,V40) 1. 下面哪个是文章中提到的那个研究的目的
选了:为了研究vulnerabilitycost对于reliable signal 的意义(meaning)
2.个细节题
答案是鸟的叫声大小不总是正确的反应鸟和receiver的距离
3.科学家研究energy cost是为了什么
我选了为了研究energy cost对reliablesignal 的影响(好像是这个意思)

作者: 是吴小智啊 时间: 2018-7-12 19:34
感谢阅读君!辛苦了!能麻烦考古一下几篇吗,我看有出现在这几天的帖子中
1. 有一題新的講美國規模經濟
P1: 美國過去很長一段時間受到內需大的關係,企業會投資來達到規模經濟(economy of scale)賺進利潤。然而在二戰之後隨著全球化市場開放競爭,中國日本等國家效法美國也達到了相近的水準,規模經濟優勢不再
P2: 作者開始解釋原因,全球競爭提高導致規模經濟優勢不再,進而使企業不願(reluctant)投入大量profit在規模上,轉而成立小但創新(small but innovative)的小公司
P3: 儘管有些學者看好這些創新會lead to 進步,最後進步導致像是當初規模經濟的成果,然而作者卻不這麼認為。作者認為隨著利潤空間變小(profits are tight),企業更不會願意投入更多的資金,而預計未來會如此形成一個惡性循環。
2.再來一篇今天的RC JJ很像"火星上有水"的,但看了才發現不一樣,這篇是"水星上有水“,回憶一下P1: 科學家本來認為水星上不會有水,因為離太陽近溫度非常高,沒有適合水存在的溫度。然而最近出來的衛星影像照片surprisingly,看到在水星北極有300~600公里的痕跡,科學家將這些痕跡和火星上南北極冰帽比較發現很像,因此認為水星上可能有冰存在。
P2: (這段架構是作者給兩個解釋)
然而為什麼水星這個高溫下會有冰存在呢? 作者認為
原因1: 水星的自轉(或是公轉?)軸與它和太陽之間的位置連線幾乎是個直角(right angle),因此造成極區(pole)有些地方不會受到太陽照射,可能有合適的低溫條件
原因2: 衛星影像是可以穿過(see through)土壤的,因此或許衛星影像拍到的痕跡是包覆在土壤之下的,土壤之下溫度沒有那麼高
題目有以下何者可能是造成有冰的原因:
選“轉軸和太陽成直角"
有一個陷阱選項是“南北極有合適溫度”,但實際上只有北極有
3.US job 与 inflation的关系,traditional economy 认为失业率低, inflation会变高,但是在某段时间点这个关系没有成立。traditional economy 试图解释这个关系的失效是暂时的, 原因有 123。但是new economy 认为失效的原因是456 有考区别原因123与456的细节题
4.讲公司要提高employee performance有两种方法,raise salary和increase bonus。Raise salary公司投入的成本更大,而increase bonus只是一次性的。
然后好像是举了一个实验,说raise salary后employee performance提高了多少多少,increase bonus后employee performance提高了多少多少,我记得是increase bonus提高的更多,因为巴拉巴拉(没记住)。但是两者一起提高对employee performance的提高最多(有题)。
还有个数学最后一题。
5.我的第四篇是由于掉库了,就出了道很简单的,说的是unionization-management的,分别给了这个概念的四个特点,就一段,半屏,不难,但有道except题比较纠结,因为考细节
以上是我从10-12日构筑分享的寂静里搜出来的,麻烦阅读君考古!谢谢!
