某鉴证中心接受委托，对两台机器设备进行鉴证，机器A为进口设备，机器B为国内设备，进口设备的技术已经过时。在对机器A进行价格鉴证时，鉴证人员用价格指数调整法估算其重置成本。在对机器B进行鉴证时，确定机器设备的贬值选用年限法。根据设备的情况和公式：实体性贬值率=设备的尚可使用年限/设备的总使用年限×100%，来确定实体性贬值。在确定功能性贬值时，鉴证人员调查得知超额运营成本较低，故不考虑所得税的影响，确定经济性贬值时，规模效益指数选取定为0.2，最后得出鉴证结论。 要求：根据上述资料，回答下列问题： 在对机器B进行价格鉴证时，功能性贬值的测算是否存在问题

Cancer The popular TV variety-show host was grim but calm. He faced the cameras and said bluntly: "I have cancer." Masataka Itsumi’’s disclosure may be the latest sign that the shame associated with cancer is finally breaking down in a country where, unlike the United Sates, the topic has traditionally been taboo. Cancer is the country’’s No.1 killer, chaining more than 230,000 lives a year. Despite the number of people affected, the subject has long been concealed in secrecy and silence. As a rule, Japanese are reluctant to tell anyone other than family if they have cancer. And doctors often lie to patients about a cancer diagnosis, fearing they would be depressed and weakened by the truth. Polls indicate that most people would prefer to be told if they have cancer. But health authorities have estimated as few as one in five cancer patients is given a truthful diagnosis. "The patient is very afraid to hear of having cancer, so many doctors just don’t tell," said one doctor. " But if we don’t tell the truth, it’’s bad for the relationship between doctor and patient. So I think this is beginning to change". He said he believed the intense public interest in the Itsumi case reflected pent-up curiosity and concern about the subject. There are other signs of greater openness in confronting cancer. Support groups for cancer victims, once unknown, have sprung up. The plot of a recent film revolved around a man with cancer. An unusually powerful television advertisement, appealing for bone-marrow donations, features a young woman who has since died of leukemia. But secrecy about cancer is still common. In Japan, serious illness is considered embarrassing. People worry about causing suffering and expense for their families, or discomforting their colleagues. Itsumi, in fact, began his news conference by apologizing. Other factors contribute to the taboo on talk about cancer. There is a cultural tendency toward restraint on discussing personal matters and stoicism in facing problems. Even if patients sense something is very wrong despite a good diagnosis, most do not press their doctors or seek a second opinion. Doctors are granted deep respect in a society that discourages questioning authority. The passage implies that______.
某工程项目分为A、B、C三个单项工程，经有关部门批准采取公开招标的形式分别确定了三个中标人并签订了合同。A、B、C三个单项工程合同条款中有如下规定： 1．A工程在施工图设计没有完成前，业主通过招标选择了一家总承包单位承包该工程的施工任务。由于设计工作尚未完成，承包范围内待实施的工程虽性质明确，但工程量还难以确定，双方商定拟采用总价合同形式签订施工合同，以减少双方的风险。合同条款中规定： (1)乙方按业主代表批准的施工组织设计(或施工方案)组织施工，甲方不应承担因此引起的工期延误和费用增加的责任。 (2)甲方向乙方提供施工场地的工程地质和地下主要管网线路资料，供乙方参考使用。 (3)乙方不能将工程转包，但允许分包，也允许分包单位将分包的工程再次分包给其他施工单位。 2．B工程合同额为9000万元，总工期为30个月，工程分两期进行验收，第一期为18个月，第二期为12个月。在工程实施过程中，出现了下列情况： (1)工程开工后，从第三个月开始连续四个月业主未支付承包商应付的工程进度款。为此，承包商向业主发出要求付款通知，并提出对拖延支付的工程进度款应计利息的要求，其数额从监理工程师计量签字后第11天起计息。业主方以该四个月未支付工程款作为偿还预付款而予以抵消为由，拒绝支付。为此，承包商以业主违反合同中关于预付款扣还的规定，以及拖欠工程款导致无法继续施工为由而停止施工，并要求业主承担违约责任。 (2)工程进行到第10个月时，国务院有关部门发出通知，指令压缩国家基建投资，要求某些建设项目暂停施工，该综合娱乐城项目属于指令停工项目。因此，业主向承包商提出暂时中止执行合同实施的通知。为此，承包商要求业主承担单方面中止合同给承包方造成的经济损失赔偿责任。 (3)复工后在工程后期，工地遭遇当地百年以来最大的台风，工程被迫暂停施工，部分已完工程受损，现场场地遭到破坏，最终使工期拖延了两个月。为此，业主要求承包商承担工期拖延所造成的经济损失责任和赶工的责任。 3．C工程在施工招标文件中规定工期按工期定额计算，工期为550天。但在施工合同中，开工日期为1997年12月15日，竣工日期为1999年7月20日，日历天数为581天。 [问题]1．A单项工程合同中业主与施工单位选择总价合同形式是否妥当合同条款中有哪些不妥之处2．B单项工程合同执行过程中出现的问题应如何处理3．C单项工程合同的合同工期应为多少天4．合同变更价款的原则与程序包括哪些内容合同争议如何解决
In studying both the recurrence of special habits or ideas in several districts, and their prevalence within each district, there come before us ever-repeated proofs of regular causation producing the phenomena of human life, and of laws of maintenance and diffusion conditions of society, at definite stages of culture. But, while giving full importance to the evidence bearing on these standard conditions of society, let us be careful to avoid a pitfall which may entrap the unwary student. Of course the opinions and habits belonging in common to masses of mankind are to a great extent the results of sound judgment and practical wisdom. But to a great extent it is not so. That many numerous societies of men should have believed in the influence of the evil eye and the existence of a firmament, should have sacrificed slaves and goods to the ghosts of the departed, should have handed down traditions of giants slaying monsters and men turning into beast--all this is ground for holding that such ideas were indeed produced in men’s minds by efficient causes, but it is not ground for holding that the rites in question are profitable, the beliefs sound, and the history authentic. This may seem at the first glance a truism, but, in fact, it is the denial of a fallacy which deeply affects the minds of all but a small critical minority of mankind. Popularly, what everybody says must be true, what everybody does must be right--"Quod ubique, quod semper, quod ab omnibus creditum est, hoc est vere proprieque Catholicum’ --and m forth. There are various topics, especially in history, law, philosophy, and theology, where even the educated people we live among can hardly be brought to see that the cause why men do hold an opinion, or practise a custom, is by no means necessarily a reason why they ought to do so. Now collections of ethnographic evidence bringing so prominently into view the agreement of immense multitudes of men as to certain traditions, beliefs, and usages, are peculiarly liable to be thus improperly used in direct defense of these institutions themselves, even old barbaric nations being polled to maintain their opinions against what are called modern ideas. As it has more than once happened to myself to find my collections of traditions and beliefs thus set up to prove their own objective truth, without proper examination of the grounds on which they were actually received, I take this occasion of remarking that the same line of argument will serve equally well to demonstrate, by the strong and wide consent of nations, that the earth is flat, and nightmare the visit of a demon. By "But to a great extent it is not so" (Lines 6--7) the author implies that
