Emotion enhances the subjective feeling of remembering, despite lower accuracy for contextual details.

Emotion strengthens the subjective experience of recollection. However, these vivid and confidently remembered emotional memories may not necessarily be more accurate. We investigated whether the subjective sense of recollection for negative stimuli is coupled with enhanced memory accuracy for contextual details using the remember/know paradigm. Our results indicate a double-dissociation between the subjective feeling of remembering, and the objective memory accuracy for details of negative and neutral scenes. “Remember” judgments were boosted for negative relative to neutral scenes. In contrast, memory for contextual details and associative binding was worse for negative compared to neutral scenes given a “remember” response. These findings show that the enhanced subjective recollective experience for negative stimuli does not reliably indicate greater objective recollection, at least of the details tested, and thus may be driven by a different mechanism than the subjective recollective experience for neutral stimuli.

Subjective qualities of memories associated with the picture superiority effect in schizophrenia.

Patients with schizophrenia (n=24) matched with 24 normal subjects were presented with both words and pictures. On a recognition memory task, they were asked to give remember, know, or guess responses to items that were recognized on the basis of conscious recollection, familiarity, or guessing, respectively. Compared with normal subjects, patients exhibited a lower picture superiority effect selectively related to remember responses. Unlike normal subjects, they did not exhibit any word superiority effect in relation to guess responses; this explains why the overall picture superiority effect appeared to be intact. These results emphasize the need to take into account the subjective states of awareness when analyzing memory impairments in schizophrenia.

优化语文课堂教学的两点体会

如何优化语文课堂教学,本文作者结合自己的教学实践,谈了两点体会:启发式≠提问式;情感———语文教学的指挥棒。     

Instructional set, interview context, and the incidence of "don't know" responses.

Examined a hypothesis formulated by E. J. Webb, D. T. Campbell, R. D. Schwartz, and L. Sechrest (see PA, Vol. 40:6543) that instructions emphasizing a respondent's importance to an attitude survey would result in a reduced number of "don't know" responses to the items. A 20-item questionnaire was administered to 180 undergraduates under 3 contexts: face-to-face interviews, telephone interviews, and group administration. Contrary to the hypothesis, in both the telephone and group administration contexts, there were significantly more "don't knows" under the instructions emphasizing the respondents' importance than with the control instructions. There was no difference between instructional sets in the face-to-face context. Results are discussed in terms of the social environments within which the questionnaires were administered.

论行政资讯公开制度中的隐私权保护

行政资讯公开制度的核心理念是公民的知情权，满足公民知的愿望是行政资讯公开制度的出发点和归宿。但同时，现代社会行政机关凭借强大的行政权能，掌握和控制了大量的个人资讯。对个人资讯的收集，利用和公开，给公民个人的隐私权带来了巨大的潜在危害。两种权利的冲突与协调构成了行政资讯公开制度的又一主题。     

Practical Role-Based Access Control

ABSTRACT

This article presents access control from a general and a role-based perspective. The article's focus is role based Access Control from a practical vice a theoretical perspective. The article starts with some access control definitions and two secure access control models. Access control is then presented in context of an abstract model, as preface to an in-depth assessment of Role Based Access Control (RBAC).

Several examples contrast RBAC and the simple access control model. The article does not portray RBAC as a panacea, optimal for all situations. Indeed, it is feely admitted that RBAC may be counterproductive in some instances. But the point is also made that RBAC, when properly implemented in an appropriate environment, can reward the organization with economic, security and accountability benefits.

Surrogacy is discussed as an essential RBAC attribute and, in practical terms, as a means of drastically reducing authorization volume.

Lastly, the article touches on converting from simpler forms of access control to the more complex RBAC.     

对一个数字图像加密算法的安全性分析

混沌系统具有的许多基本特性都可以和密码学中的混乱和扩散概念联系起来,20世纪80年代混沌理论开始涉足密码领域。混沌密码作为一类新型的密码技术,近年来成为当前信息安全领域研究的热点之一。针对一个数字图像加密算法的安全性进行了研究。指出了基于Lorenz混沌系统设计的数字图像加密算法的本质是一个移位算法,给出了算法的信息泄漏规律,以此为基础在已知明文的条件下给出了恢复算法密钥的攻击算法,对于N1×N2大小的明文图像,攻击方法的计算复杂性为(N1×N2)2/212。理论分析和实验结果均表明该图像加密算法是不安全的。     

民法视野中的知情权

论及知情权,很多学者主张是一种公权力,但是伴随着市场经济的发展和社会信息化程度的提高,人们对信息的需求逐渐增强,特别是伴随着世界各国民主主义的不断发展和国民主权观念的不断深人,知情权的内容不断丰富和扩展,其内容不再仅仅是一种公权利,而且也是一种私权利,尤其是对商业信息和个人信息的知情权,更是公民作为民事主体不可缺少的民事权利。
