Analysis of advertising lifetime for mobile phone

The market for mobile phones has increased substantially. In an attempt to maintain or increase their market share, mobile phone companies invest a significant amount of their budget on advertising. In this paper, we analyze TV advertising lifetime data of five mobile phone companies in Korea. We identify the distribution of advertising lifetime and model the median life as a function of company-specific fixed effects, type of advertising, the number of new customers signed for the service, and the number of new advertisements placed by the competitors. We show how the fitted lifetime model can be applied to advertising policy such as switching time for new advertisement.     

上市公司破产重整中债权人利益保护的实证分析

新<破产法>构建重整制度后,上市公司成为了适用该制度的主要主体.破产重整虽以社会利益为首位,但仍应对债权人的利益加以平衡保护.本文以新<破产法>实施以来被法院裁定破产重整的26家上市公司为样本,通过实证分析指出,在买壳上市的模式下,债权人由于不能分享上市公司壳资源所带来的价值,其利益实际上是处于被忽视的地位.对此,应该修改现有的债权人重整利益是否合理的评价机制以实现对债权人利益的有效保护.     

The rational kernel within Samir Amin’s mythological shell: the idea of a democratic and pluralist world political party

ABSTRACT

Amin’s Leninist-Maoist vision is unlikely to be persuasive to twenty-first century citizens. Nonetheless, there is a rational kernel in Amin’s call for a new worldwide political organization. Some structures, mechanisms and tendencies of the capitalist world economy are relatively enduring and some patterns recurrent, although the world economy is also fluid, constantly changing and evolving. Although waves of globalization have radically transformed human societies and their economic activities during the past 500 years also in many positive ways, the expansion of the international society and world economy has often been characterized by violence, imperial subjection and colonial expropriation and exclusion. There is a rational kernel also within Amin’s analysis of the current world-political situation. Command over space and time by investors and megacorporations is power. Emancipation aims at freedom from domination. The decline of the World Social Forum indicates that progressive politics must move ‘beyond the concept of a discussion forum’. My argument is that emancipation from unnecessary, unneeded and unwanted sources of determination requires global transformative agency and planetary visions about alternatives.     

手机短信的后现代审美色彩

手机短信铺天盖地,内容丰富多彩,雅俗共赏,不但丰富了现代人的闲暇娱乐生活,同时也体现出了独特的后现代审美色彩。本文试从平等自由性、解构颠覆性、游戏戏谑性、复制平面化四个方面来阐释手机短信的后现代审美特色。     

高校运用手机开展思想政治工作研究综述

手机被称为继报刊、广播、电视、网络之后的第五媒体。国内近十年来的研究表明：手机短信交流的便捷、资费低廉优势和大学生追求个性、互动的特征是高校手机文化兴盛的主要原因;手机的使用在促进大学生社会化进程的同时也对其学业、心理、道德等方面产生了消极影响;手机作为新载体有助于增强高校思想政治工作的实效,但也对传统教育管理制度构成了挑战。因此,高校应从手机文化建设、短信平台建设以及法制保障等层面予以应对,并从手机上网、传播学、心理学等视角对高校运用手机开展思想政治工作进行深入探讨。     

手机短信诈骗及治理对策

随着手机短信业务的发展,利用手机短信进行诈骗的现象也频繁发生。短信诈骗行为的泛滥,不仅严重侵犯了人们的财产权益,而且破坏了正常的社会经济秩序。为有效预防和遏制手机短信诈骗,应强化监管和打击,建立和完善手机号码实名制和储蓄实名制,加强宣传教育,多管齐下,进行综合治理。
