材料分析题

美国苹果公司联合创始人之一、前首席执行官史蒂夫·乔布斯10月5日去世,结束了他传奇的一生。某校高二文科班的同学们以“乔布斯的生平与贡献”为主题开展研究性学习,收集获取了众多资料。请你参与其中,完成相关问题:

美国总统奥巴马将乔布斯称为“美国最伟大的创新领袖之一”,赞赏他“拥有非凡的勇气去创造与众不同的事物”;苹果公司董事会发表声明说,乔布斯的才华、激情和精力是无穷无尽的创新来源,这些创新丰富和改善了人们的生活。

(1)从唯物论和认识论的角度说明为什么需要创新?

____________________________________________________________________

上世纪90年代的苹果公司一度濒临破产,乔布斯回归公司后力排众议,毅然砍掉没有竞争力的产品,使公司从濒临死亡的灰烬中复活。随后借助其卓越的软件和设计优势,推出了iPod、iPhone和iPad等创意非凡、受到人们喜闻乐见的创新产品,成功领导企业从一家传统的PC公司转型为一家电子消费品公司,并成为了美国最 有价值的企业之一。一般地说,企业的发展都要经历一个从“起始期” 、“成长期”到“成熟期”、“失败期”的生命周期,被称为“第一曲线”。为了能够实现持续发展,避免失败,企业需在高峰到来之前开辟一条新道路,这条道路发展的轨迹被称为“第二曲线”。

(2)从唯物辩证法发展的观点,谈谈苹果公司是如果实现“第二曲线”的开辟和发展的。

____________________________________________________________________

作为引领了近十年IT业潮流的公司,苹果具有太过鲜明的乔布斯印记。很多人下意识地认为,乔布斯在,苹果兴;乔布斯逝,苹果衰。乔布斯的去世,短期内并不会影响到苹果产品的风格和推出频率。有分析认为,乔布斯的几度病休反而锻炼了苹果团队,培养了接班人才,并将其个人风格变成了一种创新和经营模式,由他确定的产品哲学和团队已渗透苹果公司的肌理。今年的一项市场调查也显示,高达93%的受访者表示,苹果有没有乔布斯,都不会对自己购买苹果产品的意向产生实质性影响。不过,为了避免乔布斯去世对苹果股价造成剧烈波动,苹果公司还是在美国东部时间5日19时34分宣布临时停牌,并且暂时没有公布复牌时间。

(3)你如何看待“乔布斯在,苹果兴;乔布斯逝,苹果衰”这一观点?试运用整体与部分辩证关系的原理加以分析说明。
