虚无主义、语言和创造性：尼采与德里达的界限

尼采和德里达对虚无主义危机做出了不同的回应.这是因为作为主体解读活动及其结果,虚无主义危机本身表现出两可性:一方面,形而上学的真理意志已经演变为一种桎梏,带来了虚无主义的"虚无化"或人类创造性和历史的终结;另一方面,危机也构成主体走出形而上学的条件.德里达更注重对前者进行否定性批判,揭开了形而上学追求超验真理所带的虚无性,或追问本源所掩盖的"本源"缺失.尼采开启了这种批判,不过他更渴望逆转这种潮流,进行更具建设性的重构,而不只是把主体抛在丧失了"意义"的空场上.其目的是脱离消极的虚无主义,复兴各种冲动在主体创造性中的作用.     

马克思唯物史观对吉登斯的影响与启发

安东尼·吉登斯是当代国外马克思主义的代表性人物之一.在对历史事件的分析中,吉登斯既肯定了后现代主义对于宏大叙事的"解构",拒斥各种寻求普适性规律的观念及其理论形式,又承认能够对某些确定性的历史事件予以辨认与概括,尝试提出一种与马克思相异的历史解释理论.     

Reducing STD/HIV Stigmatizing Attitudes Through Community Popular Opinion Leaders in Chinese Markets

Reducing STDs and HIV/AIDS incidence requires campaigns designed to change knowledge, attitudes, and practices of risky sexual behavior. In China, a significant obstacle to such changes is the stigma associated with these diseases. Thus 1 campaign intervention strategy is to train credible community leaders to discuss these issues in everyday social venues. This study tested the effectiveness of such an approach on reducing HIV/AIDS stigma, across 2 years, from a sample of over 4,500 market vendors, in 3 conditions. Results showed an increasing growth in market communication about intervention messages, and concomitant declines in stigmatizing attitudes, across time, with the greatest changes in community popular opinion leaders, significant changes in intervention nonopinion leaders, and little change in the control markets.     

Parallel distributed processing and neuropsychology: A neural network model of Wisconsin card sorting and verbal fluency

Neural networks can be used as a tool in the explanation of neuropsychological data. Using the Hebbian Learning Rule and other such principles as competition and modifiable interlevel feedback, researchers have successfully modeled a widely used neuropsychological test, the Wisconsin Card Sorting Test. One of these models is reviewed here and extended to a qualitative analysis of how verbal fluency might be modeled, which demonstrates the importance of accounting for the attentional components of both tests. Difficulties remain in programming sequential cognitive processes within a parallel distributed processing (PDP) framework and integrating exceedingly complex neuropsychological tests such as Proverbs. PDP neural network methodology offers neuropsychologists co-validation procedures within narrowly defined areas of reliability and validity.     

The changing face of visual persistence

In three experiments, the effect of target luminance on estimates of visual persistence was determined on a popular successive-field task. Even though the experiments differed from each other only in terms of minor changes in stimulus conditions, very different effects were obtained across the three experiments. The different findings were attributed to the often overlooked roles of masking and target degradation on tasks of persistence. Implications for the numerous contradictory findings in the persistence literature are discussed, and the current popularity of the successive-field task is questioned.
