马克思“资本”范畴的生态本质和职能

在马克思《资本论》里,资本不仅是个历史范畴、哲学和经济学范畴,资本也是一个生态学范畴。从生态学的角度看,资本在本质上既是能够带来剩余价值的价值,同时也是能够带来剩余产品的使用价值,是二者的辩证统一。资本不仅体现了人与人之间的经济关系,也体现了人与自然之间的生态关系。在人与人的经济关系上,资本的职能就是资本对劳动的利用和剥削;在人与自然的生态关系方面,资本的职能就是资本对自然的利用和剥夺。从长期来看,资本的本质和职能存在文明化的趋势。

Advanced Math Course Taking: Effects on Math Achievement and College Enrollment

Using data from the Educational Longitudinal Study of 2002–2006, the authors investigated the effects of advanced math course taking on math achievement and college enrollment and how such effects varied by socioeconomic status and race/ethnicity. Results from propensity score matching and sensitivity analyses showed that advanced math course taking had positive effects on math achievement and college enrollment. Results also demonstrated that the effect of advanced math course taking on math achievement was greater for low socioeconomic status students than for high socioeconomic status students, but smaller for Black students than for White students. No interaction effects were found for college enrollment. Limitations, policy implications, and future research directions are discussed.     

基于“视联网”增强现实技术的教学应用研究

增强现实(Augmented Reality,AR)是在虚拟现实技术的基础上,将计算机生成的虚拟对象叠加到用户所看到的真实场景中,以构造出虚实结合的虚拟空间技术。将虚拟对象无缝的叠加于真实场景中帮助用户加强对环境的理解与情景的感知。文章介绍了当前增强现实技术的有关概念,结合其特点探索了其在教学中的应用。     

论水与农副产品的关系

由于水分子的特殊结构，使水分子有很大的极性和分子问能形成氢键，有分子问作用力强、分子内聚力大的特点．因此，使水表现出了熔、沸点高，比热容大，汽化热和熔化热高，表面张力大，介电常数高等异常特性，而含有这些特性的水对农副产品的生长发育、品质优劣、风味好坏起着十分重要的作用，同时对农副产品的贮藏、加工及食品制造都有很大的影响．     

Social contexts of development in natural outdoor environments: children’s motor activities,personal challenges and peer interactions at the river and the creek

This study examined the influence of spending time outdoors on young children’s physical and socioemotional development. We observed preschoolers’ activities in two naturally provisioned outdoor environments over the course of one year. Eleven preschoolers were videotaped continuously for 16 days at a local river and 9 days at a creek adjacent to the school. In addition to the quantitative analyses of children’s behaviors, a case study of three children’s experiences over the course of the year was conducted. Both the river and the creek settings encouraged a multitude of physical and play behaviors with similar types of affordances, including flat surfaces for running, rocks for climbing and jumping off, and water for exploration and play, but the wilder environment (river) afforded more risk and personal challenges. Observations of children’s motor activities, play and responses to challenging environmental features supported the importance of accumulated experience and social context for the development of confidence in the face of risk, individual exploration and positive social support and engagement with peers.     

对中国能源的展望

我国近年来以煤为主的能源消耗量增加迅速,已经成为仅次于美国排放二氧化碳气体的国家,影响了大气的温室效应.我国正在积极采取发展可再生能源.本文主要阐述目前我固发展可再生能源的进展状况和对新能源的开发研究情况.本文对我国可再生能源和新能源的发展作了中期预测,还阐述了石油、天然气、可燃冰(天然气的固体状态)可能大部分是星球本身固有的,不完全是由有机物产生的,这一重大理论突破引起了世界范围的争议.     

以“三童”教育特色呵护童年

回归本真,就是说要教育回归本真,要让教育真正成为发展儿童的生命、生存、生活,实现儿童的价值,引领人类文明进步.回归这样一个本真,也就是教育都是为了儿童,教育过程是儿童、教育的结果也是儿童、教育的目的更是儿童.
