关于integral from n=0 to 1 ((lnx)~2/(1+x~2))dx的计算

通过构造两个辅助函数f(t)及 φ(x) ,并分别将其展开为马克劳林级数及富里哀级数 ,在这两个级数各自收敛域内 ,当自变量t及x分别取某特定值时 ,得到同一级数 ,从而使这个积分问题得到了解决     

汉语并列短语标记隐现的认知研究

汉语中的并列短语的标记手段有两种：无标记和有标记,它们的使用并不是任意的,而是有理可据的。该文用认知语言学理论论证：标记的隐现主要相关于并列项之间语义的亲近性和其他一些制约条件。

马克思异化理论论略

马克思的异化理论的产生、完善和发展是一个理论创立过程；它所揭示的异化概念的含义极具理论的包容性和深刻性；它以深厚的穿透力解析了异化得以产生的社会根源和现实基础；它的历史地位和历史作用是任何其他“理论”和“体系”所不能企及和替代的。马克思的异化理论与黑格尔、费尔巴哈的异化思想既具有连续的继承性，更具有本质的差异性。

马克·波斯特“信息方式”理论的批判

马克·波斯特是美国当今著名的新一代马克思主义批判理论家。从上个世纪80年代起,波斯特就专注于研究新型电子媒介与批判理论的问题。他认为,新型电子媒介技术带来资本主义在20世纪晚期的一系列重大变化,致使传统马克思主义批判理论滞后抑或失效,已经变动的社会现实和新的矛盾与问题需要一套新的批判理论加以阐释和观照。让很多人认识、了解波斯特的是他提出的新理论术语——信息方式。信息方式是波斯特整个思想的核心概念,在多本著作中都有反复阐述。     

Currents and sub-currents in innovation flows: Explaining innovativeness using new-product announcements

The creation of new knowledge is a haphazard process: not every sector in an economy is equally involved. The effect of industry structure on innovativeness has been a focus of attention for a long time by both academics and policymakers. In a much quoted article, using unique data - new-product announcements - Acs and Audretsch [Acs, Z.J., Audretsch, D.B., 1988. Innovation in large and small firms: an empirical analysis. American Economic Review 78(4), 678-690] identified several characteristics of industry structure and their effects on innovativeness. By analyzing a new and more consciously compiled database, we re-examine their original claims. Our results largely support their findings: industry concentration and degree of unionization for instance hamper innovation; skilled labor promotes it. Our findings diverge in one significant respect from theirs: we suggest that the large firms do not contribute more to an industry’s innovativeness than small firms. At the industry level, we find strong support for the Schumpeter Mark I perspective of creative destruction by small firms rather than creative accumulation by large firms. In addition, we show that less dedicated innovators prove more susceptible to firm-external industry factors than more committed innovators. An unfavorable competitive environment decreases the likelihood that less successful innovators will announce new products.

Neoliberalism inside two American high schools

This article examines ‘neoliberalism’ inside two American public high schools. The work of one leading critical theorist, Mark Olssen, is explained and examined. Particular attention is paid to Olssen’s concepts of ‘homo economicus’ and ‘manipulatable man.’ It is concluded that Olssen’s theories on neoliberalism accurately describe developments in public education in the West since the early 1980s. It is also believed that his theories could benefit from a study that ‘looks inside the black box’ and reveals what neoliberalism looks like inside schools. Semi-structured interviews were conducted with 11 teachers and two principals at two public high schools in the American state of Louisiana. Analysis reveals that an educator’s sense of professional autonomy relates to students’ socioeconomic backgrounds. That is, educators at poor schools tend to have dramatically less freedom from local school boards than educators in non-poor schools.
