36 互联网使用的四大障碍
It is already received wisdom among those who are working to bridge the digital division that providing access to technology is only one of many obstacles that must be addressed. Internet access is not enough. The Children?s Partnership argues that content is one aspect of the digital division that has been neglected. The four content-related barriers to greater Internet uptake across society are:
1. local information barriers;
2. literacy barriers;
3. language barriers;
4. cultural diversity barriers.
37 完美竞争的概念及其三大要素
The theoretical ideal developed by economists to establish the conditions under which competition would achieve maximum effectiveness is known as “perfect” competition. Although rarely possible, perfect competition, as a concept, provides a useful benchmark for evaluating performance in actual markets. Perfect competition exists when （1） an industry has a large number of business firms as well as buyers; （2） the firms on the average are small; and （3） buyers and sellers have complete knowledge of all transactions within the market. The practical significance of a large number of small firms and many buyers is that the power to influence the behavior of the participants in the market is thoroughly dispersed. In other words, no single person or business has the power to dictate the terms on which the exchange of goods and services takes place. Market results then are truly impersonal. Under conditions of perfect competition, economists contend, goods and services would be produced as efficiently as possible—that is, at the lowest possible price and cost—and consumers would get the maximum amount of the goods and services they desire.
38 不同文化社会对极端行为的态度
The social consequences considered appropriate for unacceptable behavior also vary widely between, and even within, different societies. Punishment of criminals ranges from fines or humiliation to imprisonment or exile, from beatings or mutilation to execution. The form of
appropriate punishment is affected by theories of its purpose to prevent or deter the individual from repeating the crime, or to deter others from committing the crime, or simply to cause suffering for its own sake in retribution. The success of punishment in deterring crime is difficult to study, in part because of ethical limitations on experiments assigning different punishments to similar criminals, and in part because of the difficulty of holding other factors constant. |
