Exploring the moderating role of well-being on the adaptive link between self-assessment practices and learning achievement

Self-assessment practices can positively impact student learning and achievement. However, less is known about psychological moderators that can influence the impact that self-assessment practice may have on achievement. Integrating the dual processing self-regulation model and the self-assessment cycle framework, this study examined the role of students’ positive well-being in the link between self-assessment practices and domain-specific achievement scores. Hierarchical multiple regression analyses using data from 765 secondary school students revealed that self-assessment practices positively predicted achievement scores. Results also showed that positive well-being moderated the relationship between seeking internal feedback and self-reflection and achievement scores, in that the positive link between such self-assessment practices and achievement was stronger for students who had low or moderate well-being. These findings reinforce the impact of self-assessment on learning and add to the ecological validity of the dual processing self-regulation model. The discussion focuses on how these findings contribute to our understanding of how well-being could influence the adaptive role of internal and cognitive self-assessment practices in student learning. Limitations and future research directions are also discussed.     

内部能源价格相对指数对能耗的调节效应

内部能源价格相对指数可以衡量经济系统价格承受水平上的能源价格变动。以对经济系统的调节效应为切入点,引入具有“一般均衡”属性的内部能源价格相对指数,采用OLS回归、E-G两步法协整检验和岭回归等方法,构建直接效应和综合调节效应模型。结果验证了价格相对指数通过调节能源技术效率和经济总量抑制能源消耗在理论上可行,但其对于产业结构调节的路径存在阻滞。而不同波动周期的能源价格在调节能源技术效率控制能耗方面存在显著的“对称”调节效应,能源价格下降期对技术效率改进的忽视和价格恢复期的低效与非理性使能耗陷入恶性循环。结合我国实际：当前节能需要考虑多渠道的综合调节作用,合理提升能源价格应与利用能源价格波动周期和加快技术效率提升等并行,以最终降低能耗。

随着高校办学规模的不断扩大,经济活动的日益增多,内部审计工作显得越来越重要。本文对高校内部审计工作的现状进行了分析,提出了改善高校内部审计工作的对策,以期为加强高校内部审计提供参考。     

道教.张三丰.太极拳

道教作为我国本土的一个宗教,在我国的历史发展中有着重要的推动作用。而张三丰作为道教中一个有名的道士,他在道教的地位和影响力及养生术都留下了不可磨灭的痕迹。张三丰作为太极拳的创始人一说至今还存在分歧。本文主要从太极拳的技术特点、养生理论和张三丰在道教的地位和影响力及他的养生思想去分析太极拳和张三丰的关系。     

体院健美操专项学生内部动机与学业成绩的相关研究

参照北京体育大学教授张力为博士,2004年编写的由北京体育大学出版社出版的《体育科学常用心理量表评定手册》书中的内部动机量表,对健美操专项学生实施内部动机测量[1]。研究结果表明,在内部动机测量的7项指标中,不同等级成绩水平的学生在兴趣/乐趣、主观能力和压力3项指标上存在显著性的差异（P〈0.05）,其他各项指标努力、主观选择、价值/有用性和相关性不存在显著性的差异（P〉0.05）。可见,不同等级成绩学生在努力、主观选择、价值/有用性和相关性的指标上处于同一水平,而指标兴趣/乐趣、主观能力和压力对学生学习健美操的成绩具有一定的影响。     

随机共振机制在图像复原中的应用

随机共振能将噪声的部分能量通过非线性系统作用转为信号的能量,从而提高输出信号的信噪比,这为解决从强噪声背景中检测提取有用弱信号问题提供了一种全新的思路和方法。将随机共振机制应用于图像复原,可以提高图像复原效果,特别是在处理被强噪声污染的图像信号时。     

Running-induced patellofemoral pain fluctuates with changes in patella water content

Abstract

Although increased bone water content resulting from repetitive patellofemoral joint loading has been suggested to be a possible mechanism underlying patellofemoral pain (PFP), there is little data to support this mechanism. The purpose of the current study was to determine whether running results in increases in patella water content and pain and whether 48 hours of rest reduces patella water content and pain to pre-running levels. Ten female runners with a diagnosis of PFP (mean age 25.1 years) participated. Patella water content was quantified using a chemical-shift-encoded water-fat magnetic resonance imaging (MRI) protocol. The visual analog scale (VAS) was used to quantify subjects' pain levels. MRI and pain data were obtained prior to running, immediately following a 40-minute running session, and 48 hours post-running. Pain and patella water content were compared among the 3 time points using one-way ANOVA's with repeated measures. Immediately post-running, persons with PFP reported significant increases in pain and exhibited elevated patella water content. Pain and patella water content decreased to pre-running levels following 48 hours of rest. Our findings suggest that transient changes in patella water content associated with running may, in part, contribute to patellofemoral symptoms.
