ABC公司有三个业务类似的投资中心，使用相同的预算进行控制，其1997年的有关资料如下：

项　目	预算数	实　际　数
		A部门 　　　　　B部门　　　　　　C部门
销售收入 营业利润 营业资产	200 18 100	180　　　　　　　210　　　　　　　200 19　　　　　　　 20　　　　　　　　18 90　　　　　　　100　 　　　　　　100

在年终进行业绩评价时，董事会对三个部门的评价发生分歧：有人认为C部门全面完成预算，业绩最佳；有人认为B部门销售收入和营业利润均超过预算，并且利润最大，应是最好的；还有人认为A部门利润超过预算并节省了资金，是最好的。
假设该公司资本成本是16%，请你对三个部门的业绩进行分析评价并排出优先次序。

国际经济争议与国内经济争议相比，它具有什么样的特点？

An awkward-looking character such as Cyrano de Bergerac might sniff at the suggestion, but recent scientific research shows beauty, brains and brawn may in fact all be allied, writes Dr Raj Persaud.

(46) Psychologists have concluded that we may be drawn to the stereotypically attractive because of what their faces reveal about their intelligence and success in later life. In American, research led by Professor Leslie Zebrowitz, of Brandeis University, has shown an association between facial attractive and IQ. Strangers briefly exposed to a target’s face were able to correctly judge intelligence at levels significantly better than chance.

The same team also researched how a person’s attractiveness might bear relation to their intelligence. They found that good-looking people did better in IQ tests as they aged. (47) Their research sought to prove that how a person perceived himself and was perceived by others predicted how intelligent he apparently became more accurately than his past intelligence. (48) Perhaps because the more attractive people were treated as more intelligent, they ended up having more stimulating and, therefore, intelligence-enhancing lives.

Does this mean that your face really could be your destiny Sociologists Dr Ulrich Mueller and Dr Allan Mazur, of the University of Marburg in Germany, recently analyzed the final year photographs of the 1950 graduates of West Point in the United States. Dominant facial appearances turned out to be a consistent predictor of later-rank attainment:

Again, they believed there could be a self-fulfilling effect. (49) Because some men looked more authoritative, they naturally drew respect and obedience from others which, in turn, assisted their rise through the ranks.

A team at the Royal College of Surgeons in Dublin has been investigating the sensitive subject of links between physical and mental abnormalities. Led by Doctors Robin Hennessy and John Waddington, the team used a new laser surface-scanning technique to make a 3-D analysis of how facial shape might vary with brain structure. Their findings showed that in early fetal life, brain and face development are intimately connected. From this they concluded that abnormalities in brain elaboration probably also affect face development.

This, according to them, explains the striking facial features of some one with Down’s syndrome. (50) Using similar techniques, the team also demonstrated how other disorders linked to brain aberrations could be associated with facial alterations.

So the very latest scientific research suggests that nobody should try to look too obviously different from average.
