AI 111. “Because of recent advancements in business and technology, the overall quality of life in most societies has never been better than at the present time.” AI 119. The following appeared as part of the business plan of the Capital Idea investment firm.
“Across town in the Park Hill district, the Thespian Theater, Pizzazz Pizza, and the Niblick Golf Club have all had business increases within the past two years. Capital Idea should therefore invest in the Roxy Playhouse, the Slice-o’-Pizza, and the Divot Golf Club, three new businesses in the Irongate district. As a condition, we should require them to participate in a special program: Any customer who patronizes two of the businesses will receive a substantial discount at the third. By motivating customers to patronize all three, we will thus contribute to the profitability of each and maximize our return.”
Discuss how well reasoned . . . etc. RC: 1 Pond: By cityhunter996 7月7日
北美 6. 一篇有关pond, permanent pond and espademic pond, 通过研究tripod的存活的，差不多是现象解释型，4段，一段提出现象，2段给出解释说是因为短池水会消失其中的生物也会死亡所以资源有限，蝌蚪会少。3段又说不对，因为有些短池的蝌蚪比长池多，无法解释。所以提出另一因，是天敌少。4段总结3段表明作者支持3。 补充：那espademic pond （又叫Fresh Water Pond. 我也忘了原单词, 但文章有解释）指那种经常被弄干的，估计就是人工鱼塘，因为很多动物不能再没水环境中发育，所以科学界曾认为fresh water pond里的蝌蚪不会比Permanent pond多。后来研究说明是因为在fresh water pond的蝌蚪的数量不多，而且天敌也吃掉了其余大部分的蝌蚪。所以lucky没被吃掉的就不用compete with other蝌蚪，也就快乐成长了。而生长在permanent pond的就往往因为同类的Competition而用尽了resource。 2 Company investment: By cy6077 7月11日 RC1:短 讲美国企业于某一年代为什么lose竞争力,共二段, 先attribute to 企业不愿增加投资于外在产能上,但随后又举钢铁业及航空业为反例,说它们投资很多,依然赔钱失去竞争力,到第二段的中后段才冒出 – 要投资在内部(如员工训练..),才是增加竞争力的商道.出题点好象在这二观点打转. 补充：文章结论是公司要做好decision making, invest in the right place. 3: Benchmarking 说公司要喜欢比较，一般的benchmark方法有三种：1）compare with past performance (using survey to develop). 2) compare with whole industry (hire research firm or buy research report) & 3) with direct competitors CR GWD-1 Q39
