universal

We present a theory of frustrated, two-dimensional, quantum antiferromagnets in the vicinity of a quantum transition from a non-collinear, magnetically-ordered ground state to a quantum-disordered phase. Using a sigma-model for bosonic, spin-1/2, spinon fi

UNIVERSAL STUDIO(环球影城)网上广告与行销

挑战

环球影城发行了“外星人”这部经典电影的DVD。这次商业活动的目的是使这部电影成为最受喜爱的电影。这个DVD有全新的、从未发布过的内容，并加强视觉效果。商业活动成功与否最重要的衡量标准是引起购买兴趣的产生。目标受众在25～49岁之间。

商业活动

电视是商业活动的基石，占预算的94%。大致6%的预算投放在旗帜广告上，不到1%的预算投放在富媒体广告上，指的是网页上的浮动广告，即所谓的覆盖技术。

方法论

Marketing Evolution调研了部分消费者，这些消费者都是环球以前的目标观众。标准在主要的品牌衡量中改变。(所谓的连续性跟踪研究)。媒体组合最优化研究分析了那些看到电视广告和网络广告的受众。电视观众在活动推广前，推广中和完成后都进行了调研，以此来衡量看到广告的观众认知度的增长情况。在线广告的衡量基于显露与非显露方法，而不是Marketing Evolution推崇的著名试验设计(归咎于数据收集员对该研究的限制)。Marketing Evolution开发了一种合理的技术来消除显现与非显现模型的影响，以此达到与试验设计类似的结果。

结果

研究中最令人震惊的发现体现在商业活动中富媒体广告的效果
