The study the speaker cites in the argument seems persuasively and powerfully support his assertion, however, a careful scrutiny would finally disclose how unscientific the comparative study between the two groups is and how arbitrary the conclusion—all patient should be suggested to take antibiotics as a part of their muscle strain recovery treatment---is.(很好的开头,指出错误)
To begin with, except the variables, other factors and conditions in a scientific experiment must be designed and controlled in the same way, or the data obtained would be highly suspected. Unfortunately, four unknown or changeable aspects, at least, in the comparison experiment above would undermine the preciseness and accuracy of the study, which, thus, could hardly substantiate the hypothesis pointed in the first sentence, let alone lead to the conclusion of the argument.
The first factor is the experiment controller, the primary mistake. If Dr. Newland, specializes in sports medicine, could be an expert probably with a regimented research training and owning a clear understanding towards the sports hurt, the controller of the other group, the general physician, at the risk of sounding cold,is just an amateur for his background. From my perspective, the experiment should use only one specialist to control the whole process in order to make sure the accuracy and consistency. Besides, even if it must use two controllers, another controller should leastwise be a professional surgeon.
The second factor is about the sugar pills the group two took in the study. In order to exclude other factors potentially affect the result of an experiment and only focus on the drug effect of antibiotics, the control group should take nothing during the experimental process. Why the group 2 should take the sugar pills? Would the sugar pills contain antibiotics ingredient or other ingredients? Or have the participants eaten the sugar pills regularly? 问得好!Unfortunately, the speaker does not offer more information to resolve these questions.
The third question is about the number of the participants in the experiment. Many figures terms such as 40 percentage or average, are indicated in the speaker’s expression only missing out the significant number of the two groups. Neither could the reader recognize if the samples are representative or not, nor could them know whether the participants in the two groups are same. 学习!
The forth is about the interpretation of the experiment result which is extremely fuzzy. For the group one, no data is provided to explain what is “typically expected” or how it could be assumed. For the second, what is the ratio of “the significantly reduced” people? And for the both, which degree does the recovery of individuals run up to? It is very possible that the subjects in group one do not recover completely while the people in the comparative group recover reach up to 100%.哇塞!GREAT!
Moreover, apart from the four huge flaws in the experiment mentioned above, at the even worse, the speaker seems too hasty to publish the experiment result in the newsletter to the public merely based on a preliminary—the first step—study.
Providing the study is OK, this is not to say that that all patients diagnosed with muscle strain would be recommended to take antibiotics in their treatment. First of all, one specialist should hold a prudent attitude towards the application of a new medicine. As a general rule, first he has to start a clinical trial to the new drug and then report the result to the public. Second, if the result of the clinical trial is detected ???the medicine is safe to be taken, should the all patients be suggested to use this new medicine? I would say no: in part because that certain particular group such as pregnancy, young kids or old people, need to be treated greatly cautious when encouraging them to take this medicine(心思慎密啊~学习); in part because no evidence reveals whether the antibiotics have side effects, for instance, allergy, inflammation, tract injury or drug resistance and so forth; and in part, it appears, because whether the drug could be permitted by the government is uncertain--maybe the production of antibiotics would result in serious pollution or perhaps the medicine would contain prohibited ingredients.感觉扯远了吧= = So the conclusion that all people should be well advised to take antibiotics to cure their muscle stain is still hanging to be proved whether it is feasible.
To be sure, the speaker’s conclusion is unconvincing and presumptuous. To persuade the public well, he should provide a detailed experiment report and meanwhile, avoid the same errors existing in the following-up study高见!. Moreover, he should still hold a cautious attitude towards the application of the antibiotics medicine
恩 看组长的文章总是要受到很大很大的启发,无论是语言还是观点,好好学习~
文章对study的合理性进行有力详细的攻击,可惜没提到secondary infections。虽然整篇文章考虑严谨,罗列众多逻辑错误,但是有相当一部分可归结为study的问题。文章开头说Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain---------句中有一个may!! 也就是说即使study证明了antibiotics有效果,最多只能说明可以治疗muscle strain,但是ms的康复受二次感染影响的猜测未得到证实!!!
如果在精彩的实验合理性攻击后加上这点,也许更有意思~
拙见~~~写了那么多不发表点意见多不好意思
这里的study攻击值得模仿,哈哈~ |
