The impact of repetition-induced familiarity on agreement with weak and strong arguments.

Repeated statements are perceived as more valid than novel ones, termed the illusion of truth effect, presumably because repetition imbues the statement with familiarity. In 3 studies, the authors examined the conditions under which and the processes by which familiarity signals from repetition and argument quality signals from processing of message content influenced agreement with persuasive arguments. Participants with low or high motivation to process information were presented persuasive arguments seen once or twice. In all 3 studies, repetition increased the persuasiveness of weak and strong arguments when little processing of message content occurred. Two of the studies used a process dissociation procedure to reveal that both greater controlled processing (which reflected argument content) and the greater automatic influence of familiarity (which reflected repetition) were associated with increased acceptance of strong arguments but that greater controlled processing dissipated the benefits of familiarity for agreement with weak arguments.

多支路负荷闪变源识别研究

闪变是电能质量的问题之一,对其进行定位研究,可以明确供电方、用电方的责任,为综合治理提供了一定的理论依据。研究了闪变产生的原因及其在变压器间的传递规律。闪变源支路负荷将引起所连接的母线电压波动,但其通过的电流受负荷本身特性影响,与母线电压关系不大,而非闪变源支路负荷通过的电流取决于母线电压。根据这一特点,通过计算母线电压和支路负荷电流相关度的新方法,能够实现多个支路负荷的闪变源识别,该方法简单、易行,满足准确度的要求。     

无取向电工钢平整工艺研究

 板形和表面质量是无取向电工钢的重要质量指标。为了提高叠片系数,必须保证无取向电工钢表面光滑、板形良好。针对攀钢冷轧厂普通连续退火生产线生产无取向电工钢存在的板形和表面质量问题,以带材前张应力横向分布均匀作为目标函数,建立了一套针对无取向电工钢平整机的辊型曲线及工艺参数优化数学模型,开发了无取向电工钢专用平整工艺及配套的平整机辊型曲线,使无取向电工钢平整轧制力为8~20吨、平整张应力10~40兆帕,平整延伸率小于0.1％,在保证产品板形和表面质量条件下,保证了产品电磁性能要求。

A structured dialogue tool for argumentative learning

This paper presents a structured environment for Computer‐Supported Collaborative Argumentation, which we call the Argumentative Learning Experience (ALEX). The system aims to improve understanding of argumentation and to widen and deepen the space of debate among 16–18‐year‐old students. To use ALEX users make arguments by selecting and completing partial sentences. An automatically created visual representation of the argument is displayed and personalised advice on the argumentation is provided to each user.     

Distributed Parallel Computing Using Navigational Programming

Message Passing (MP) and Distributed Shared Memory (DSM) are the two most common approaches to distributed parallel computing. MP is difficult to use, whereas DSM is not scalable. Performance scalability and ease of programming can be achieved at the same time by using navigational programming (NavP). This approach combines the advantages of MP and DSM, and it balances convenience and flexibility. Similar to MP, NavP suggests to its programmers the principle of pivot-computes and hence is efficient and scalable. Like DSM, NavP supports incremental parallelization and shared variable programming and is therefore easy to use. The implementation and performance analysis of real-world algorithms, namely parallel Jacobi iteration and parallel Cholesky factorization, presented in this paper supports the claim that the NavP approach is better suited for general-purpose parallel distributed programming than either MP or DSM.     

A lapse in constructive dialogue: The Journal's responsibility.

Using the concept of constructive dialogue (Altman & Davies, 2003), the author believes there has been a serious lapse in responsibility in Mills' (2006; see record 2006-03254-016) response to commentaries published in Psychoanalytic Psychology. He believes that there was a failure of editorial responsibility to maintain a basic level of scholarly, as opposed to ad hominem, discussion in these pages.
