游戏机手柄上盖注射模设计

文章分析了游戏机手柄上盖塑料件的工艺特点,介绍了游戏机手柄上盖注射模结构设计和工作过程。该模具采用浇口开设在顶杆上,在分型时实现自动拉断凝料,同时将曲面分型改为平面分型,降低模具加工的难度,节约成本和提高注塑、脱模的稳定性。生产实践证明,该套模具结构合理,运行可靠。     

论MDO视域下的教学设计

利用多学科设计优化(MDO)对教学系统进行总体设计,是对传统教学设计的一大拓展。传统教学设计不能很好地实现各个学科之间的协同效应,所取得的最终设计结果往往不是系统的全局最优解。基于MDO的教学设计能在很大程度上克服传统教学设计的弊端,实现教学设计的整体效益最大化。     

CoFe2O4的磁性和交换偏置场研究

“留白”是中国画中的一种绘画技法,指的是国画中对空白部分的留取。中国画利用“留白”来营造出虚实相生的意境,同样,现代平面设计也可以利用“留白”的手法,在继承传统的基础上进行创新。通过“色彩留白”及“构图留白”两种设计方式,使设计作品获得更好的版面视觉效果。同时,“留白”中的传统艺术精神,还能够丰富设计的文化内涵,增加平面设计作品的意境。通过将“留白”运用于平面设计中,对于创作优秀的平面设计作品有积极意义。     

石家庄六线隧道模型试验相似材料研究

满足相似关系的模型材料是模型试验成功的关键。在调研相似材料研究现状的基础上,依托石家庄六线隧道模型试验项目,应用量纲分析法推导出了相关参数的相似判据。根据相似原则,以粘聚力和摩擦角为主要相似判据,选用重晶石粉、石英砂和凡士林的混合物为模型材料,通过正交设计法研制出了地层相似材料。以抗压强度为相似判据,选用石膏材料为模型材料,研制出了灌注桩和锚索注浆体相似材料。     

Maltreatment prevention through early childhood intervention: A confirmatory evaluation of the Chicago Child-Parent Center preschool program

Increased recognition of the consequences associated with child maltreatment has led to greater emphasis on its prevention. Promising maltreatment prevention strategies have been identified, but research continues to suffer from methodological limitations and a narrow focus on select prevention models. This investigation uses data from the Chicago Longitudinal Study to examine mediating mechanisms that link the Chicago Child-Parent Center preschool program to a reduction in overall child maltreatment and, more specifically, child neglect. We use structural equation modeling to test child, family, and school measures hypothesized to mediate the effects of CPC participation on maltreatment and neglect. Results indicate that a substantial proportion of the program's impacts can be accounted for by family support processes, including increased parent involvement in school and maternal educational attainment as well as decreased family problems. The CPC program's association with reduced school mobility and increased attendance in higher-quality schools also significantly mediated its effects on maltreatment and neglect. Further, a decrease in troublemaking behavior contributed modestly to mediating the program's association with maltreatment but not neglect. We discuss the implications of these results for the field of maltreatment prevention.     

Staging language: An introduction to the sociolinguistics of performance

Staged performance involves the overt, scheduled identification and elevation of one or more people to perform, with a clearly demarcated distinction between them and the audience. It involves the agentive use of language, building on the foundation of existing social meanings. Staged performances tend to be linguistically stylized, pushing the limits of language creativity. They have the potential to trigger significant sociolinguistic effects, circulating novel forms and contributing to language change. The paradigms used in this theme issue for approaching language performance include Bakhtin's notion of Stylization, Bell's Audience and Referee Design, Silverstein's Indexicality, Agha's Enregisterment, and Bauman's construct of Discursive Culture. Themes that run through the articles include: a concept of identity that is part product, part process; the centrality of the audience; the reflexivity of staged performance; and the importance of non‐linguistic modalities such as music and appearance. The language analysis in this collection of papers concentrates mainly on phonological features of varieties of English, finding instances of selectivity, mis‐realization, overshoot and undershoot in their performances of a range of targeted dialects.
