解释社会问题的不同理论视角有哪些?[首都经济贸易大学]
相关试题:简述社会整合理论。[社科院]
背景资料: 某高速公路M合同段,路面采用沥青混凝土,路线长19.2km。该路地处平原地区, 路基横断面以填方3~6m高的路堤为主,借方量大,借方的含石量40%~60%。地表 层以黏土为主,其中K7+200~K9+800段,地表层土厚7~8m,土的天然含水量为 40%~52%,地表无常年积水,孔隙比为1.2~1.32,属典型的软土地基。结合实际情 况,经过设计、监理、施工三方论证,决定采用砂井进行软基处理,其施工工艺包括加 料压密、桩管沉入、机具定位、拔管、整平原地面等。完工后,经实践证明效果良好。 在施工过程中,针对土石填筑工程,项目部根据作业内容选择了推土机、铲运机、 羊足碾、布料机、压路机、洒水车、平地机和自卸汽车以及滑模摊铺机等机械设备。在 铺筑沥青混凝土路面面层时,因沥青混凝土摊铺机操作失误致使一工人受伤,并造成设备故障。事故发生后,项目部将受伤工人送医院治疗,并组织人员对设备进行了抢修, 使当天铺筑工作顺利完成。
问题:
1.本项目若采用抛石挤淤的方法处理软基是否合理?请说明理由。
2.根据背景资料所述,按施工的先后顺序列出砂井的施工工艺。
3.选择施工机械时,除了考虑作业内容外,还应考虑哪些因素?针对土石填筑施工,项目部所选择的机械是否妥当?请说明理由。
4.项目部还应做哪些工作来处理该背景资料中的机械设备事故?

语言素材:
Good teacher
To be a good teacher,you need some of the gifts of a good actor;you must be able to hold the attention and interest of your audience;you must be a clear speaker,with a good,strong,pleasing voice which is fully under your control;and you must be able to act what you are teaching,in order to make its meaning clear.
Watch a good teacher,and you will see that he does not sit still before his class: he stands the whole time he is teaching;he walks about,using his arms,hands and fingers to help him in his explanations,and his face to express feelings. Listen to him,and you will hear the loudness,the quality(音色)and the musical note of his voice always changing according to what he is talking about.
The fact that a good teacher has some of the gifts of a good actor doesn't mean that he will indeed be able to act well on the stage,for there are very important differences between the teacher's work and the actor's.The actor has to speak words which he has learnt by heart;he has to repeat exactly the same words each time he plays a certain part,even his movements and the ways in which he uses his voice are usually fixed beforehand(预先).What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play: they ask and answer questions, they obey orders, and if they don't understand something, they say s0. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
I have known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.
A公司拟并购B公司,为保证并购活动顺利推进,需对B公司的价值进行评估。A公司工作人员采用市场法,从市场上选取了B公司相似的C、D、E公司作为参考,相关数据如表4所示。另预计B公司本年度销售额20000万元、账面价值14000万元、经营净现金流量2000万元。

为筹措并购资金,工作人员还设计了两种融资方式。
方式一:采用增发普通股方式筹资,已知增发普通股的股价为每股21元,预计本年每股发放股利1元,股利年增长率为5%。
方式二:采用发行5年期企业债券方式筹资,债券面值为100元,发行价格为100元,票面年利率为5%,到期一次还本付息(单利计息),发行费费率为0.5%,不考虑债券兑付手续费,所得税税率为25%。
工作人员提出了甲、乙两种融资方案,甲方案融资方式一与融资方式二筹措资金额比值为3:7,乙方案比值为5:5。
问题(计算部分要求列出计算过程,最终计算结果保留两位小数):
1.用市场法估算B公司的价值。
2.若采用融资方式一筹措并购资金,不考虑其他因素变动的影响,用股利增长模型法测算A公司增发普通股的资金成本。
3.若采用融资方式二筹措并购资金,计算A公司发行企业债券的所得税后资金成本。
4.假设方式一的资金成本为10%,方式二的所得税后资金成本为5%,采用比较资金成本法计算甲、乙两种融资方案的平均资金成本,并选择最佳融资方案。
