媒介企业核心竞争力及其培育

为了能在激烈的市场竞争中立于不败之地,商业企业越来越认识到培育核心竞争力的重要性。对于我国的媒介企业,随着开放政策逐步付诸实施和竞争态势的日益加剧,其培育核心竞争力的必要性也显得越来越迫切。本文在对大量文献进行评析的基础上,从媒介企业经营的核心环节———对受众注意力价值高度关注的角度出发,提出了媒介核心竞争力的培育,应该是合理的受众定位、适当的内容组织和有效的营销方式三者构成的完整系统的观点。     

对沉默者"实"利的坚守--论赵树理对农民的关注视角

三晋文化中"实"的浸染与底层人生阅历中对"实"的体认,使赵树理无论是参加社会革命实践活动,还是文艺创作,都把这种为农民"实"利的追寻当成了自己最高的价值取向.这种价值标准使赵树理在关注农村时呈现出与鲁迅异样的特色,同时造成了他一系列的命运波折.     

Polyhedral combinatorics of the cardinality constrained quadratic knapsack problem and the quadratic selective travelling salesman problem

This paper considers the Cardinality Constrained Quadratic Knapsack Problem (QKP) and the Quadratic Selective Travelling Salesman Problem (QSTSP). The QKP is a generalization of the Knapsack Problem and the QSTSP is a generalization of the Travelling Salesman Problem. Thus, both problems are NP hard. The QSTSP and the QKP can be solved using branch-and-cut methods. Good bounds can be obtained if strong constraints are used. Hence it is important to identify strong or even facet-defining constraints. This paper studies the polyhedral combinatorics of the QSTSP and the QKP, i.e. amongst others we identify facet-defining constraints for the QSTSP and the QKP, and provide mathematical proofs that they do indeed define facets. Author now works at Motorola. (2005 onwards)     

论广告信息促动的知觉机制

在广告对受众发生作用的过程中,注意力是受众接受和理解广告的第一道知觉屏障,广告影响受众的第二道知觉壁垒是受众对信息的解释和理解.因此,在广告信息战略和具体创意中,为创造能最大程度吸引人们注意的广告,必须做到三点:一是提供具有实际价值的信息;二是充分利用受众对信息的选择性接触;三是保持信息多样性;四是追求有趣性信息.广告信息在受到注意后,为了让信息转换朝预期方向发展,还必须创造诸多便于记忆的方式,帮助人们达成轻松自然的回忆,并促使受众由注意力转向理解.     

等亮度条件下范畴信息对预搜索的影响

考察等亮度条件下新旧客体之间的范畴关系对预搜索(preview search)的影响.以字母和数字为范畴材料,以搜索一个靶子字母(H)或数字(6)为任务,以预搜索为实验范式.结果表明:(1)当旧客体为数字而靶子为字母时,产生了完整的预搜索效应;(2)当旧客体为字母而靶子为数字时,只产生了部分预搜索效应.这些结果显示,在等亮度条件下,范畴信息有助于产生预搜索效应,而且存在非对称性.     

独善其身:诗人理性深永的心灵超悟

从独善其身诗篇产生的社会心理可知，有不少诗人正是通过追求山水林野之美来追求独立于封建伦理规范之外的人生理想。诗人对于自然界的崇高感觉就是对于自身行为的崇敬，而经由某种暗换赋予了一自然界对象。独善其身的诗人往往从内向的默省中体味人生，他们的诗篇中往往既表现了对官场的厌倦，又表现出对黑暗现实的愤懑之情。

Antecedents and Consequences of Words

As instances of behavior, words interact with environments. But they also interact with each other and with other kinds of behavior. Because of the interlocking nature of the contingencies into which words enter, their behavioral properties may become increasingly removed from nonverbal contingencies, and their relationship to those contingencies may become distorted by the social contingencies that maintain verbal behavior. Verbal behavior is an exceedingly efficient way in which one organism can change the behavior of another. All other functions of verbal behavior derive from this most basic function, sometimes called verbal governance. Functional verbal antecedents in verbal governance may be extended across time and space when individuals replicate the verbal behavior of others or their own verbal behavior. Differential contact with different verbal antecedents may follow from differential attention to verbal stimuli correlated with consequential events. Once in place, verbal behavior can be shaped by (usually social) consequences. Because these four verbal processes (verbal governance, replication, differential attention, and verbal shaping) share common stimulus and response terms, they produce interlocking contingencies in which extensive classes of behavior come to be dominated by verbal antecedents. Very different consequences follow from verbal behavior depending on whether it is anchored to environmental events, as in scientific verbal practices, or becomes independent of it, as in religious fundamentalism.
