维果茨基对现代西方心理学的影响 总被引:1,自引:0,他引:1
麻彦坤 《华东师范大学学报(教育科学版)》2006,24(3):67-72
维果茨基对现代西方心理学产生了巨大而广泛的影响,融入了蔚为壮观的“维果茨基现象”。他提出了与西方迥然不同的理论体系与方法论思想,丰富了心理学的理论宝库,广泛影响了心理学发展的众多领域;激发了心理学的文化转向,促进了跨文化心理学、文化心理学等心理学分支学科的发展;迁入并影响了后现代心理学,从工具论和方法论等方面启发了社会建构论心理学的孕育和发展。 相似文献

Development of an evaporation crystallizer for desalination of alkaline organic wastewater before incineration 总被引:2,自引:0,他引:2
A wastewater evaporation-desalination pretreatment method was introduced to remove the Na^+ and K^+ salts in volatile organic compounds (VOCs) wastewater before it was fed into the incinerator. VOCs in the wastewater were volatilized in the evaporation system and then the vapor was combusted in an incinerator. Simulated phenol wastewater containing sodium chloride was evaporated and concentrated and sodium chloride was crystallized in different parameters. The experimental results showed that the higher initial concentration of sodium chloride increases the ratio of volatilization of VOCs, which was due to the effect of “salting out” (a decrease in the solubility of the nonelectrolyte in the solution, or more rigorously, an increase in its activity coefficient, caused by the salt addition (Furter and Cook, 1967)). When evaporation speed was increased from 1.67 ml/min to 2.73 ml/min, the total removal coefficient of sodium chloride was about 99.88%-99.99%. This pretreatment procedure eliminates the slag phenomenon caused by Na^+ and K^+ salts during wastewater incineration, so the incinerator could operate continuously, and the wastewater evaporation could increase the heat value of wastewater, and the operation cost would be reduced. 相似文献

长期以来,贫困大学生的经济求助一直是社会关注的焦点,经济上的重负,往往导致心理上也承受着巨大的精神压力,所以贫困大学生的“精神求助”更加不容忽视。较大的经济压力、学业压力和人际交往困难导致贫困大学生产生诸多心理问题,我们应该有针对性地开展心理健康教育、心理辅导和行为指导等一系列的心理救助工作,帮助贫困大学生摆脱经济贫困与心理贫困的双重压力,为贫困大学生的健康成长开辟一奈绿色通道。 相似文献

Recent studies on the stability of school academic performance across school subject areas show two weaknesses: a lack of research attention to elementary schools and a lack of adequate statistical adjustments for school characteristics. With data describing elementary students (N = 6,883 students in Grade 6 in 148 schools) from the New Brunswick School Climate Study (NBSCS), the current study examined correlates of academic performance across mathematics, science, reading, and writing among students and among schools, using a multivariate multilevel model with statistical adjustments for student characteristics and school context and climate characteristics. Results indicated that (a) students were differentially successful in different subject areas, (b) schools were differentially effective in different subject areas, and (c) the differential success was more obvious among students than among schools. Findings of this study call for a new type of school programs that aim to ensure that students progress equally in different subject areas and for stronger school policies that systematically coordinate classroom or department practices. 相似文献

Prolonged farrowing remains one of the critical challenges in intensive pig farming. This study aims to explore the effects and mechanism of Yimu San (YMS), a Chinese veterinary medicine micro mist, on delivery ability with mouse models. Thirty-two pregnant mice were randomly divided into a control group and low-YMS, med-YMS, and high-YMS groups. The labor process time and stillbirth rate were recorded, the levels of serum oxytocin and prostaglandin E2 (PGE2) were measured with enzyme-linked immunosorbent assay (ELISA). Contractility measurements of the isolated uterus and the expression of connexin 43 (Cx43) in uterine smooth muscle were evaluated. The results showed that compared with the control group, the birth process time and stillbirth rate in the med-YMS and high-YMS groups were remarkably lower. The in vitro uterine contractions, levels of oxytocin, PGE2, and Cx43 in the med-YMS and high-YMS groups were significantly higher than those in the control group. The differences of the above measurements between the low-YMS group and the control group were not obvious. It can be speculated that YMS could significantly promote labor in pregnant mice by enhancing the levels of oxytocin, Cx43, and PGE2. 相似文献
