The Concept of Information Overload: A Review of Literature from Organization Science, Accounting, Marketing, MIS, and Related Disciplines   总被引：1，自引：0，他引：1  

Martin J. Eppler  Jeanne Mengis 《The Information Society》2004,20(5):325-344

Based on literature from the domains of organization science, marketing, accounting, and management information systems, this review article examines the theoretical basis of the information overload discourse and presents an overview of the main definitions, situations, causes, effects, and countermeasures. It analyzes the contributions from the last 30 years to consolidate the existing research in a conceptual framework and to identify future research directions.  相似文献   

Transform domain technique for windowing the DCT and DST     

B.G. Sherlock  Y.P. Kakad 《Journal of The Franklin Institute》2002,339(1):111-120

In this paper, an algorithm is developed to apply Hann, Hamming, Blackman and related windows directly in the transform domain for the discrete cosine transform and discrete sine transform. These algorithms are useful in applications where windowing is required in order to minimize edge effects caused by implicit symmetries in the transform domain that are not replicated in the real-world data. Examples of such applications include data communication, adaptive system identification and filtering, real-time analysis of financial market data, etc. Software implementations in C language are also given.  相似文献

Implicit attitudes toward children may be unrelated to child abuse risk     

Risser HJ  Skowronski JJ  Crouch JL 《Child abuse & neglect》2011,35(7):514-523

Objective

To explore whether adults possess implicit attitudes toward children and whether those attitudes are especially negative among respondents who are high in child physical abuse (CPA) risk.

Methods

The present study used an implicit evaluative priming procedure. In this procedure, participants were instructed to make decisions about the evaluative implications of target words. These words were preceded by photographs of child faces or adult faces displaying positive, neutral, or negative expressions. Reaction times for the evaluative decisions were used as an index of the extent to which photos invoked negative or positive evaluative reactions.

Results

Results from 2 studies, the first conducted on a student sample (N = 90) and the second on a parent sample (N = 95), demonstrated that evaluative congruence between the facial expressions displayed in photographs and the target words facilitated responses. Furthermore, the results suggested that regardless of CPA risk, child faces, relative to adult faces, facilitated responses to negative target words, suggesting an out-group bias. This implicit out-group bias was not moderated by respondents’ CPA risk status.

Conclusions

Faces of children, relative to faces of adults, appear to activate negative information structures that facilitate evaluative decisions of negative stimuli, suggesting an out-group bias. Given that out-group biases typically lead to less favorable treatment of out-group members, additional research is needed to examine the pervasiveness of negative evaluative biases towards children and the potential implications of such biases on children's lives. Further, research examining whether high CPA risk parents and low CPA risk parents differ in how they manage initial negative evaluative reactions is needed.  相似文献

论信息处理模型下的外语写作教学     

邓昊熙 《安徽职业技术学院学报》2011,10(3):77-80

文章从心理语言学的角度出发,对外语写作过程中的信息处理模型做初步分析,结合多种信息处理模式,指出多种信息资源为争夺有限的认知资源而处于相互冲突的关系,因此外语写作需要认知资源的综合运用,是一个认知资源分配和整合的复杂过程。外语写作过程既包含串行处理和并行处理,又包含自上而下和自下而上的综合,同时也涉及自动化处理和受控处理的综合运用。如何减轻外语写作过程中的认知负担是教师和学习者必须思考并共同努力回答的问题。  相似文献
