听力原文：W: I just read a curious fact. Did you know that people who spend less than ten minutes in a drugstore are five times more likely to make a purchase than those who spend half an hour there？
M: I saw that article, too. But think, if someone runs into a drugstore for ten minutes, it's usually to make a specific purchase.
W: And someone who spends more time there may be just looking.
M: Exactly. Haven't you ever gone into a store thinking that you'd like to buy something, and then talk yourself out of it？
W: Yes, I have, especially when I thought I would get it for less elsewhere, or I really didn't need it after all.
M: Exactly. But if you run into the store, wanting to buy something specific and have very little time. You pick it up, pay for it immediately and then leave.
W: That's true. Maybe we should learn a lesson from that. Take your time and you'll spend less money.
M: I doubt if that would be true in all stores, though. In a department store, for instance, you may see a sweater or something you never intended to buy, and buy it because you have time to look around.

One major purpose of this study was to demonstrate whether or not the newer social re search techniques could help in broadening and deepening knowledge concerning juvenile delinquency(少年犯罪). Construction of the design was guided by this goal of exploring new methods ill the analysis of juvenile delinquency. However, research technique developed in one content area can not be mechanically transferred to another. A new application of them requires substantial changes and it is these innovative modifications which this study offers as its contribution.
Juvenile delinquency has been the subject of many previous studies using a variety of re search techniques. This study makes an additional contribution by using a design specially planned to permit a comparison of several approaches.
The drawing-up of the study design profited greatly from an extensive survey of previous researches on crime, undertaken during the earliest stage of the project. It was found that most studies could be classified as belonging to one or more of three broadly conceived types: social background study, family background study and personal motivation study.
Each type has its characteristic design and mode of interpretation and each has produced information of considerable importance. Yet no attempt was made in any of the studies to integrate one or more of these three design types. It became apparent that one of the major contributions a pilot study could make to both method and substantive findings would be to bring all three study types together in one design for the purpose of correlating(使相互关联) their find rugs and evaluating their relative importance in producing data of use to the practitioner.
In the first paragraph, the author draws an analogy between ______.
