重新认识马克思主义的阶级理论

在社会转型期,随着我国社会结构的变化以及随之出现的新的社会阶层,传统的阶级理论及其分析方法面临着挑战。因此,有必要对马克思主义的阶级理论进行重新认识。本文通过论述经典作家对马克思主义阶级理论的论述,对比马克思主义的阶级理论与韦伯的阶层理论的区别,阐明对这一理论的认识。     

Differential isotopic fractionation in benthic foraminifera and paleotemperatures reassessed

Different species of benthic Foraminifera taken at the same level in an Atlantic core yielded different oxygen isotopic values. It was therefore impossible to deduce paleotemperature values. In addition, pelagic and benthic species showed the same isotopic variations, an indication that pelagic and benthic species reflect only the variation of oxygen-18 composition of the ocean.
