"I'm OK but You're Not" and Other Peer-Relational Schemas: Explaining Individual Differences in Children's Social Goals.

This study examined the links among 5th and 6th graders' (279 girls and 310 boys) self- and peer perceptions, social goals, and social behavior. Social goals mediated the effects of self- and peer perceptions on 3 types of behavior: proactive aggression, prosocial behavior, and withdrawal. In addition to their main effects (self-perception predicting variance in agentic goals, peer perception being related to communal goals), self- and peer perception interacted in influencing social goals; for instance, the effects of a positive view of oneself were different in the contexts of a positive versus a negative perception of peers. It is suggested that in order to predict children's social behavior more accurately, researchers should investigate children's dual perceptions of themselves and of their peers--that is, their peer-relational schemas--instead of assessing self-perception and peer perception in isolation from each other.

Moderators of the Relationship Between Implicit and Explicit Evaluation.

Automatic and controlled modes of evaluation sometimes provide conflicting reports of the quality of social objects. This article presents evidence for 4 moderators of the relationship between automatic (implicit) and controlled (explicit) evaluations. Implicit and explicit preferences were measured for a variety of object pairs using a large sample. The average correlation was r = .36, and 52 of the 57 object pairs showed a significant positive correlation. Results of multilevel modeling analyses suggested that (a) implicit and explicit preferences are related, (b) the relationship varies as a function of the objects assessed, and (c) at least 4 variables moderate the relationship: self-presentation, evaluative strength, dimensionality, and distinctiveness. The variables moderated implicit-explicit correspondence across individuals and accounted for much of the observed variation across content domains. The resulting model of the relationship between automatic and controlled evaluative processes is grounded in personal experience with the targets of evaluation.

再结晶和相变的交互作用对双相钢组织特征的影响

系统地研究了不同的热处理工艺对双相钢组织特征的影响。研究的结果表明,存在一个临界两相区退火温度。当退火温度高于此临界退火温度,双相钢组织表现出带状铁素体的特征;而低于临界温度的退火可以得到典型的马氏体和铁素体等轴状组织的特征,这是由于冷轧钢板在两相区退火过程中的相变和再结晶过程交互作用的结果。当相变先于再结晶发生时会形成带状铁素体。预先的低温再结晶处理可以消除铁素体带状组织。

双振动电机同步最优控制方法

应用最优控制理论,提出新的双振动电机的相位同步控制策略。双振动电机在振动机械,如振动筛、振动打桩机及振动成型机等,有着广泛的应用。现代的双振动电机以相位控制同步方式工作,而目前采用的主要是主从跟踪式PID控制同步方法。这种方法虽然实现简单,但控制效果较差。基于最优跟踪控制技术,在状态空间中对双振动电机系统的振动频率和相位差同时进行控制,取得了较满意的实验结果。该控制技术可以很方便地被推广到对3台以上的振动电机进行多机相位同步控制中。
