Distinctiveness and Correlation in Conceptual Structure: Behavioral and Computational Studies.

Patients with category-specific deficits have motivated a range of hypotheses about the structure of the conceptual system. One class of models claims that apparent category dissociations emerge from the internal structure of concepts rather than fractionation of the system into separate substores. This account claims that distinctive properties of concepts in the living domain are vulnerable because of their weak correlation with other features. Given the assumption that mutual activation among correlated properties produces faster activation in the normal system, the authors predicted a disadvantage for the distinctive features of living things for unimpaired adults. Results of a speeded feature verification study supported this prediction, as did a computational simulation in which networks mapped from orthography to semantics.

浑水波涌灌溉的节水机理与效果

通过大田试验研究，表明在浑水波涌灌溉条件下，表土致密层的形成与发展是含沙水流中泥沙逐渐“挂淤”、“落淤”与“入渗滞留”等作用的结果。随着灌水周期的进展，表土致密层的糙率与入渗能力也随之减小，这就为以后各周期的灌溉水流创造了一个加速水流推进与提高减渗效果的新界面，从而达到节水与提高灌水质量的目的。从4个与浑水有关的节水率分析可见，浑水波涌灌溉的节水效果是泥沙与间歇共同作用的结果，其中泥沙作用是主要的。     

模糊自动机在电磁波识别中的应用

研制了一个模糊处理和神经网络相结合的自动机,使用模糊技术从未处理的电磁信号波纹图像中处理模糊几何特征属性,进行波纹分类与识别。当使用模糊自动机(FA)进行识别紊乱波纹时,这些模糊几何特征是最好的。而对这些模糊几何特征的辨识,使用FA是很好的。     

Role of perfectionism and personality disorder features in response to brief treatment for depression.

Using data from the Treatment of Depression Collaborative Research Program (TDCRP), the authors compared the role of patients' perfectionism and features of personality disorder (PD) in the outcome of brief treatment for depression. Data were extracted as to patients' intake levels of symptoms; perfectionism; and PD features, measured as continuous variables, as well as their symptoms at termination; their contribution to the therapeutic alliance; and their satisfaction with social relations. Poorer therapeutic outcome was demonstrated for patients with elevated levels of perfectionism and odd-eccentric and depressive PD features. Patients' contribution to therapeutic alliance and satisfaction with social relations were predicted by perfectionism but not by PD features. Results highlight the central role played by patients' personality in the course of brief treatment for depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

郑411块超稠油试油试采工艺技术应用
