51.抗生素对于肌肉损伤的作用
The following appeared in a medical newsletter.
"Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment. "
医生长期以来怀疑严重肌肉扭伤后的二次感染妨碍了一些患者迅速康复。这一假说现在被一项对两组患者的研究的初步结果所证实。第一组患者全部由专攻运动医学的Dr. Newland治疗肌肉损伤,他们在疗程中经常服用抗生素。他们的康复期平均比通常预期的快40%。第二组患者由综合医师Dr. Alton治疗,他们被给予糖丸,而患者相信他们在服用抗生素。他们的平均康复时间没有明显缩短。因此,任何被确诊为肌肉损伤的患者应被建议服用抗生素作为辅助治疗。使之成立的条件
--------逻辑线--------
(背) sec-inf有碍sev-ms的恢复
2组study of ms: 快40%( D.N special, anti), 无reduce(D.A general, no-anti)
ms都应该用anti
C ( ms ( ser-ms ( inf ( 其他因素anti ) ) ) )
--------提纲--------
1.(样品)两者人ms程度没有说
a)都是普通ms, 或者sev-ms但没有sec-inf, anti的作用没有意义
b)其次是本身身体情况没有, 预期康复时间的估计就不准确
2.(背景因素)两个医生的全部治疗
a)即使样品都sec-inf
b)医生不同治疗不同, 前期处理(sec-inf程度轻), 后期康复训练(sec-inf恢复快)都对实际康复时间有影响
3.(没有根据的类比)即使证明了sec-inf要服用了anti, 也不能 -> ms都要服用anti
a)不是所有ms都sev-ms
b)不是所有sev-ms都sec-if
潜在后果,厌恶治疗,滥用anti导致副作用.
53.儿童早期的羞涩原因
Thirteen years ago, researchers studied a group of 25 infants who showed signs of mild distress when exposed to unfamiliar stimuli such as an unusual odor or a tape recording of an unknown voice. They discovered that these infants were more likely than other infants to have been conceived in early autumn, a time when their mothers' production of melatonin — a hormone known to affect some brain functions — would naturally increase in response to decreased daylight. In a follow-up study conducted earlier this year, more than half of these children — now teenagers — who had shown signs of distress identified themselves as shy. Clearly, increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life.
13年前,研究者研究了一组在受到不熟悉的刺激比如不寻常的气味和未知声音的录音时表现出轻微紧张的25名婴儿。他们发现这些婴儿比其他婴儿更可能在早秋怀孕,而早秋是他们的母亲分泌的melatonin--一种已知会影响一些大脑功能的荷尔蒙--因日照的减少而增加的季节。在今年早些时候所作的跟踪调查中,这些表现出紧张迹象的儿童--现在已经是十几岁--有一半以上认为自己害羞。显然,出生前melatonin的增加导致婴儿期的羞涩并且这种羞涩将延续至生命更晚的阶段。
--------逻辑线--------
13AY study: 25baby 对us(oder, voice) md
可能是mel+的关系(早球, 日照减少)
Now study: (25)一半认为自己害羞
C: mel导致害羞, 并延续到老
--------提纲--------
1.这25baby的md不一定有因为mel增多的关系
a)样本太小,样本情况没有说明,这些baby本身就比较敏感
b)实验内容没有可取性, 大多数baby对us(oder, voice)都会md
c)冬天日照时间更短, 冬天怀孕的baby是不是更md?
2.这(25)一半认为自己害羞不一定一因为baby时期的md
a)男女孩的差别有没有考虑?
b)回答是否客观?
c)这期间的成长经对他们的害羞有没有养成的因素
3.这种害羞也不会延续到老
a)没有根据, 人长大后会不那么害羞
203.大医院与小医院
The following appeared in a newspaper feature story.
"At the small, nonprofit hospital in the town of Saluda, the average length of a patient's stay is two days; at the large, for-profit hospital in the nearby city of Megaville, the average patient stay is six days. Also, the cure rate among patients in the Saluda hospital is about twice that of the Megaville hospital. The Saluda hospital has more employees per patient than the hospital in Megaville, and there are few complaints about service at the local hospital. Such data indicate that treatment in smaller, nonprofit hospitals is more economical and of better quality than treatment in larger, for-profit hospitals.
在Saluda镇的小型非盈利医院,患者平均逗留时间是两天;在邻近的Megaville市的大型盈利医院,患者平均逗留时间为6天。而且,Saluda医院患者的治愈率大约是Megaville医院的两倍。Saluda平均每个患者对应的医务人员的数量比Megaville医院多,而且地方医院关于服务的投诉也较少。这些数据表明小型非盈利医院的治疗比大型盈利医院更加经济,质量更高。
--------逻辑链--------
S医院 avg 2days, M医院 avg 6days
Cure rate: S = 2*M
Emp/pat rate: S > M
Complaints: S < M
--------提纲--------
1.治疗时间和cure rate不能说明treatment质量
a)小院治小病, 大院治大病, 小病治疗时间短
b)小院治小病, 大院治大病, 小病治愈率高
2.Emp/pat rate和Complaints不能说明服务质量
a)Emp/pat rate高是不是说明小医院组织问题, 效率低
b)Complaints率是多少?
3.作者忽略了一个重要问题,医院的选择首映应该是从医院治疗范围去选择,小医院治小病,大院治大病
a)大医院才能治疗疑难杂症, 小医院不行, 否则会延误治疗
b)小医院便宜, 数目多, 比较容易去, 小病去大医院会造成不方便和浪费
7.市长选举之环境污染问题
The following appeared in a letter to the editor of the Clearview newspaper.
"In the next mayoral election, residents of Clearview should vote for Ann Green, who is a member of the Good Earth Coalition, rather than for Frank Braun, a member of the Clearview town council, because the current members are not protecting our environment. For example, during the past year the number of factories in Clearview has doubled, air pollution levels have increased, and the local hospital has treated 25 percent more patients with respiratory illnesses. If we elect Ann Green, the environmental problems in Clearview will certainly be solved."
在下一次市长选举中,Clearview的市民应投Good Earth Coalition成员Ann Green的票,而不是Clearview市委成员Frank Braun,因为当前的市委成员没有保护我们的环境。举例来说,去年Clearview的工厂数量翻了一番,空气污染水平增加了,而且当地医院因呼吸道疾病就诊的数量增加了25%。如果我们选举Ann Green,Clearview的环境问题肯定将被解决。
--------逻辑链--------
应该AG(GEC), 不应该FB(TC)
TC不关心环境
P1Y : fact*2, air pollute level+, +25% respire ill
--------提纲--------
1.Letter没有说明现在C市有空气污染问题
a)工厂增加,但是这些工厂的废气排放量没有做说明
b)空气增加了,但是没有任何的对照
c)呼吸病人增加了可能是因为流感或者传染病.
2.Letter也没有说明现在C市有污染问题
a)所以FB和town council没有关注
b)即使有,可能也不是空气污染问题,很可能是水污染,垃圾围成等其他污染
3.选mayor要综合考虑
a)除环境政策外,其他的因素也很重要(经济发展,医疗,教育等等)
b)FB当选后可能会加强对环境的关注,现在FB和town council不关注可能是没有问题
c)AG所在的Good Earth Coalition关注什么没有说,很可能AG的关注点不在环境污染这块.
结论:选mayor应该综合考虑多方面,如果这样片面的选择可能letter都无法解决
188.男女对疼痛的不同感觉
A new report suggests that men and women experience pain very differently from one another, and that doctors should consider these differences when prescribing pain medications. When researchers administered the same dosage of kappa opioids — a painkiller — to 28 men and 20 women who were having their wisdom teeth extracted, the women reported feeling much less pain than the men, and the easing of pain lasted considerably longer in women. This research suggests that kappa opioids should be prescribed for women whenever pain medication is required, whereas men should be given other kinds of pain medication. In addition, researchers should reevaluate the effects of all medications on men versus women.
一项新报告表明,男性和女性对于疼痛的感受是有显著差异的,医生在开止痛药方的时候应该考虑到这种差异。当研究者把相同剂量的kappa opioids--一种止痛药--分发给智齿刚刚被拔除的28名男子和20名女子的时候,女性报告的她们感受的痛楚要比男性小的多,而且止痛的时间女性更长。这一研究说明当需要止痛药时,应该给女性服用kappa opioids,而应该给男性服用其他的止痛药。而且,研究人员应该重新评估所有药品对于男性以及女性的效用。
--------逻辑链--------
Research: 拔WT(28男, 20女), 同dose的KO, 女的report less pain, longer time
女的都给KO
男的给other meds
Reevaluate all meds
--------提纲--------
1.Research不准确
a)样本太小
b)女的意志力更好, 所以女的report less pain, longer time
c)男的WT状况比较糟糕, 牙大难拔
2.作者的结论放大了
a)KO对WT(女)有用, 但是不是对所有痛疼(女)有用
b)KO对WT(男)没用, 但是不是对所有痛疼(男)没用
3.作者的建议没有可行性
a)大部分药在男女是没有差别的, 男和女身体的大部分系统都是的相同,骨骼,机构,呼吸,消化,循环系统,估计不同的就只有生殖系统,大部分的疾病,男女都可以使用
b)太浪费钱了, 也许存在差异的,但是差异太小,对这些的研究的耗费就是浪费了
186.上司在场时员工的工作效率
The following is a recommendation from the director of personnel to the president of Professional Printing Company.
"In a recent telephone survey of automobile factory workers, older employees were less likely to report that having a supervisor present increases their productivity. Among workers aged 18 to 29, 27 percent said that they are more productive in the presence of their immediate supervisor, compared to 12 percent for those aged 30 or over, and only 8 percent for those aged 50 or over. Clearly, if our printing company hires mainly older employees, we will increase productivity and save money because of the reduced need for supervisors. "
在最近一次对汽车工厂工人的电话调查中,年纪大一些的员工更少报告说有管理员在场会提高他们的生产效率。在18到29岁的员工中,27%的人说当他们的顶头上司在场时更有效率,相比之下,30岁及以上的工人只有12%,50岁及以上的工人只有8%这样认为。显然,如果我们印刷公司主要雇佣年级大一些的员工的话,我们的劳动生产率将会提高,并且节省开支,因为对于管理员的需求将会减少。
--------逻辑线--------
Tel survey: old less report incre; 18-29(27%) report incre, 30-50(12%) report incre, 50+(8%) report incre
Hire old, less adm, incre, lower cost
--------提纲--------
1.调查不可靠不能说明老员工效率比年轻员工高
a)样本范围没有说明,
b)本身的效率,年轻人就会高, 而提高部分是多少也没有说
2.错误类比
a)印刷厂和汽车厂工作类型不同毕竟汽车有很多装配工作不能够完全自动化,那么印刷厂的工作节奏更高,更快,一旦进入工作状态,偷懒的可能行更小.
3.adm不应该是一项可以节省的成本
a)作者认为管理员是一项可以节省成本,因为他们的作用只是用来监督员工.但是管理员的职责范围远远大于监督,他们需要管理工作,调度任务,班次安排,物资管理等等,如果这些方面都忽略了,试问谁来完成以上的工作?
169.小城镇之男女教授
The following appeared in a letter from a department chairperson to the president of Pierce University.
"Some studies conducted by Bronston College, which is also located in a small town, reveal that both male and female professors are happier living in small towns when their spouses are also employed in the same geographic area. Therefore, in the interest of attracting the most gifted teachers and researchers to our faculty and improving the morale of our entire staff, we at Pierce University should offer employment to the spouse of each new faculty member we hire. Although we cannot expect all offers to be accepted or to be viewed as an ideal job offer, the money invested in this effort will clearly be well spent because, if their spouses have a chance of employment, new professors will be more likely to accept our offers."
对于同样位于小城市的Bronston学院所作的一些研究发现,不论男性或女性教授,当他们的配偶在相同的城市有工作时,就更乐于在这些小城市生活。因此,为了吸引最有天分的教师和研究人员加入我们的员工队伍并提高我们员工的士气,我们Pierce大学应该为每一个我们所雇佣的新员工的配偶提供就业机会。尽管我们并不期望所有就业机会都会被接受或被看作是理想的工作,我们在这项努力上的投入显然是值得的,因为如果新教授的配偶有就业机会,他们将更乐于在我们学校就职。
--------逻辑线--------
对B学校的研究: Spou在, 就愿意stay在st
为吸引人才, 给new faculty 的spou工作(不是全都是理想的)
--------提纲--------
选择工作的标准
1.错误类比,认为两个地方的所有条件都相同的,B的工作种类和薪酬都比较高,工作机会也比较多.
2.老员工就不用了?配偶们都对这些工作满意?
3.作者对居民选择工作的标准发生了误解,只要配偶在相同城市工作他们就会留在原职位,那工作前景,待遇,本地生活历史文化等方面的因素呢? |
