Submarine Pipeline Routing Risk Quantitative Analysis

A new method for submarine pipeline routing risk quantitative analysis was provided, and the study was developed from qualitative analysis to quantitative analysis. The characteristics of the potential risk of the submarine pipeline system were considered, and grey-mode identification theory was used. The study process was composed of three parts: establishing the indexes system of routing risk quantitative analysis, establishing the model of grey-mode identification for routing risk quantitative analysis, and establishing the standard of mode identification result. It is shown that this model can directly and concisely reflect the hazard degree of the routing through computing example, and prepares the routing selection for the future.

Chinese secondary school students’ conceptions of assessment and achievement emotions: endorsed purposes lead to positive and negative feelings

Student perceptions of the purposes of assessment have been shown to be significant predictors of self-regulated learning. Their relationship to achievement emotions is less well understood. This paper reports a survey study of Chinese middle and high school students (N = 1,393) self-reported conceptions of the purpose of assessment and their achievement emotions using inventories with previously developed Chinese versions. While pre-existing models were not replicated, exploratory techniques developed well-fitting measurement models for each inventory and a structural equation model showed that significant variance in achievement emotions was elicited by certain beliefs about assessment. Positive emotions of pride and enjoyment depended primarily on conceptions that assessment (1) contributed to student moral and skill development, (2) was accurate, and (3) was not for evaluating schools or teachers. Negative emotions of anger and shame depended primarily on conceptions that assessment was (1) for evaluating schools and teachers and (2) not for improving teaching and learning. Thus, student emotional responses to assessment in China logically depend on beliefs that assessment reliably relates to developing their own learning, skills, and moral character.

战略科学家典型特征量化评估：探索与实证研究

培养造就更多的战略科学家,是实现我国高水平科技自立自强的重要命题。为响应中央要求,支撑对战略科学家的“选育留用”,文章综合采用胜任力模型的多种研究方法,基于国内外155位标杆人物的典型案例,构建战略科学家典型特征量化分析指标体系,并选取297家国家重点实验室的720名领军人才作为战略科学家后备力量代表,对指标体系进行实证分析。研究发现,我国战略科学家后备力量代表与标杆人物相比,存在战略眼光与实践能力方面差距显著、企业战略科学家力量偏弱、学科分布与我国发展战略需求错配等问题,并据此提出了相关对策和建议。
