It took me some time to answer such silly question as which city is American capital. Time is so valuable that we can not afford to waste.
The JT money seems play a role in check or download. I am a new comer. I have to earn some JT money.
How can I get more JT money? I don't waste time to play silly games.
Do something more practical and helpful.

Issue 88"Technologies not only influence but actually determine social customs and ethics."

The development of technology greatly promts the advancement of produce acitivity, thus drive the progress of civilization. I agree it influences social customs and ethics. But to say it determine the later would be untenable from my point of view.

First of all, the long history of human being never shows the syncronous development of technology and ethics, or shows any evidence that ethics developed later the technology revolution. Chinese people show great respect to the senior citizens long long ago. And today this custom does not show any sign of immediate change. This custom does not change as the technologis do. That Japanese women show more respects to men than men to women seems little change while we experienced great revolution in automobile, computer and other information technology.

Foundamentally, technology and customs are two different things. Any change in technology will directly improve the quality of a product or the efficiency of service. The later may gradually affect the manner people have in their social activities. While, customs in a society are accumulation of many influences that may be traced to past experience and life style. For example, the use of computer and IT in office and home greatly improve the efficiency in communication. But we still have the basic relationship with other people. As an employee, we have boss and colleagues. As a family man, we have to performe a man's duty. All these do not change as any technology does. To say techonology determine the custom is ungrounded or rediculous.

Technology does gradually affect our life. In the past we highly rely on post service to mail our letter. But now we can send our message using cellular phone or email to many people in seconds. However this shows technology improves efficiency. The revolution in techonology may change the work style thus new relationships may develop. In the agriculture dominated society, men work in the field while women mostly stay in home to take care of children. In modern time, both men and women can all work in the same office or do the same job. Women have more chances to try for equal right and equal pay. This scenori would not occur in the agriculture dominated society. It is hard to say the politics constutution, culture and customs today are exactly same as that 100 years ago.  Technology does influence our society, but in a gradual way.

In summary, techonology directly affects the efciency in the place where it is applied. It may influence people in a gradual way. But there is no way to say it is able to determine the customs and ethics which forms as a deposit of history.

The following appeared in a magazine focusing on health and fitness.
argument 96."A recent study of several nutritional supplements showed that subjects who took a daily pill containing luceen had significantly better vision of distant objects than subjects in the study who took other nutritional supplements. Luceen appears naturally in a tasty fruit that grows on the island of Bonopia, and very few inhabitants of that island wear eyeglasses or other corrective lenses. Such evidence suggests that people who develop vision problems should take regular luceen supplements."

At first glance, this message looks very good for people like me who suffers the near-sighted for years. After all, it provides some "evidence" to show the ffect of the luceen. However, careful check the message, I found the conclusion would be sound if the statistic data are of good quality and the reason why the people in the island where the fruits grow to be extracted to make luceen is clearly linked to the effect of luceen.

First of all, the message does not provide any information about the number of subjects who take the servey and how long the subjects take the pill of luceen. If over one thousand of subjects took the servey, the statistic data may say some thing about the effect. But if only a small group of subjects like 2 to 3 students reported the good effect, it will not be as credible as the form one.

Second, the message fails to tell us how the subjects who have taken the pill of luceen improved their eye sight. If the amplitude is insignificant, we probably don't have to try this new product. Or the reason these subjects improved their eyesight is due to luceen or some other reason like special health program. The causal link is not clear at all.

Furthermore, the message fails to provide the comparison with similar product that is conducive to the eye health. As a consumer, I prefer product that has high ratio of effect over price. If another medicine has better effect and less expensive, why do I bother luceen.

The mesage does not tell us why the people on the island don't have glasses. They may never have eye disease or they even don't know what eye glasses are. They have good ey sight maybe because of the seafood they eat or the water they drink. If these are true, the contribution from luceen would be more difficult to prove.

Anyway, the evidence provided in the message if far from convincing. It is a poor argument with so many flaws. Although I suffer a lot from eye near-sighted, I will not try any step to close to the luccen.

February 5, 2010 issue
"because learning is not a solitary activity but one that requires collaboration among people, students of all age will benefit academically if they work frequently in group."

I disagree that all students should work more in group no matter their ages are. Actually age plays an important role in students altitude toward learning. The effect of learning is also intengent on what subject is learned or studied.

First of all, learning of elementary school students is much different from learnig as an adult. Young children prefer learning during play. Learning in group is the best form. Children can compete with each other. They can imitate teachers or their classmates in many things. Imitation is the first step in learning. However, for an adult students like graudate students, they will become independent researchers, engineers or doctors. They can not often put the questions they are engaged to other people's desk. Everyone has his/her own major and specified thing to do. Of curse these adult students have somethings in common. Like the professionals they may participate profession conference once a year, they may take part in seminar weekly. But they can never have meeting every hour like elementary students do.

For specified studies, learning is to practice in which group activity might be harmful. For example, a graduate student who attempts to check a hypothese or model may need more time to design his plan, to prepare his tools (computer programs or experiment instruments), to operate experiments, to record results and to analyze them. He may consult others when he has difficulty, but he will spend most time alone. It is unreasonable for him to put all his work to a group. On one hand, every body has his own job and focus. On the other hand, the thing he needs to do is a long list. Maybe he has patent, thus he won't let other people to know his business.

Group learning or individual study depends on the psychologic factors. Young children hardly focus their attention longer than a few hours, But an adult student can work on the same project over years. The young children are not grown ups, they are unmature in psychological term. Thus we can not treat young students as adult students.

Anyway, young students may need more chance to learn together so they can learn from each other  and learn more lively, while adult students need more time learn by himself. The acadimical development requires independence altimately. Thus we can not say say students of all age have the same benefit when they learn in group.
