Adolescents’ personal conceptions of intelligence: The development of a new scale and some exploratory evidence

This study presents the building of an instrument to measure personal conceptions of intelligence based upon Dweck research, and some exploratory evidence. The instrument is directed to adolescents, has got more items than the original one and incorporates new aspects, such as the importance of effort and ability in relation with personal conceptions of intelligence. The results of a factor analysis evidenced the existence of two distinct factors — a static and a dynamic one — that explain together 31.7% of the total variance. The internal consistency of the scales evidenced alpha coefficients between .74 and .80. The results of a test-retest reliability study (with a month interval) proved to be better for the static scale than to the the dynamic one, as well as the results of an external validity study (correlations with grade point average). Some differential exploratory studies showed differences in personal conceptions of intelligence related to school grades (5th to 11th): the scores increased from the 5th to the 11th grade, showing that older students were less “static” (more “dynamic”), and also related to the socio-economic status (high vs. low): the higher SES subjects appeared less “static” (more “dynamic”) than the lower SES subjects.     

水电建设项目风险评价方法概述

水电建设项目受地质、地理位置,气候等一些自然或非自然因素的影响,不可避免地存在诸多风险因素,业界相继对风险识别、风险分析以及风险评价等做了深入研究,但鲜有人概括了水电建设项目前的常用的风险评价方法。通过对水电建设项目前存在的风险评价方法进行概括,在其中提出了一种新的改进的评价方法,并比较分析了各自的适用条件以及优缺点,能为水电建设项目合理选择使用评价方法提供了有效的参考依据,进而能使风险预测与客观实际相接近。

流动家庭学前儿童早期阅读教育存在的问题及对策——以上海松江区为例

早期阅读教育是幼儿语言教育的重要组成部分。流动家庭学前儿童早期阅读教育无论在理论层面还是实践层面受关注的程度远远不够。流动家庭学前儿童早期阅读教育存在意识淡薄,目标单一,内容狭窄,方式简单、机械,环境不容乐观等问题。流动家庭学前儿童的早期阅读教育可以通过提高家长对早期阅读教育的认识以及引导孩子合理收看电视节目、建立流动图书馆等策略加以改善。

Yangxueqingnao particles inhibit rat vascular smooth muscle cell proliferation induced by lysophosphatidic acid

Objective: To observe the effect of Yangxueqingnao particles on rat vascular smooth muscle cell (VSMC) proliferation induced by lysophosphatidic acid (LPA). Methods: The amount of3H-TdR (3H-thymidine) admixed in cultured rat VSMC was measured and mitogen-activated protein kinase (MAPK) activity and lipid peroxidation end product malondialdehyde (MDA)content of the VSMC were assayed. Results: 1×10-9, 1×10-8, 1×10-7 mol/L LPA in a concentration dependent manner, induced the amount of 3H-TdR admixed, MAP kinase activity, and MDA content of the cultured rat VSMC to increase. However, 5%, 10%,and 15% Yangxueqingnao serum preincubation resulted in a decrease of 23.0%, 42.0%, and 52.0% (P＜0.01) respectively in the amount of 3H-TdR admixed, a decline in VSMC MAP kinase activity of 13.9% (P＜0.05), 29.6% (P＜0.01), and 48.9% (P＜0.01)respectively, and also, a decrease in MDA content of VSMC of 19.4%, 24.7%, and 43.2% (P＜0.01) respectively, in the 1×10-7mol/L LPA-treated VSMC. Conclusions: LPA activates the proliferation and lipid peroxidation of VSMC in a concentration dependent manner. The LPA-induced VSMC proliferation is related to the activity of MAP kinases, enzymes involved in an intracellular signalling pathway. The results of the present study showed that Yangxueqingnao particles can effectively inhibit LPA-induced VSMC proliferation, MAP kinase activation, and reduce lipid peroxidative lesion.
