当代欧美“共同性”思潮的演进

当下流行于欧美学界的“共同性”思想尚未在国内学界被系统研究,但这股思想潮流不仅是国外学界前沿理论动态,更是马克思主义最新思想资源。“共同性”思想根植于近年来在欧美流行的公地运动及其相关研究,以及在这一实践与理论进程中产生的治理方法与公地形态两个层次的突破性进展。以奈格里、哈特等人主导的思想共同体作为参考点,对目前“共同性”思想的整体发展情况可从两个层面展开分析:从对话性补充一侧来看,这一思想共同体内部的拓展,使得“共同性”从物的单一维度拓展至物—关系的双重维度,并最终将“共同性”锚定为一种生产方式;从论战性批判一侧来看,针对“共同性”思想的自治主义政治取向、公地运动渊源和马克思主义理论底色,各自形成了分别基于上述三个维度的批判。更进一步地,激进左翼学者将从公地研究中抽象出的“共同性”思想与马克思主义传统中的共产主义思想相结合,试图一方面借助最新的思想与实践资源在当代激活马克思曾提出的共产主义设想,一方面又以共产主义自身深厚的历史积淀来为“共同性”思想注入革命力量。

凯洛瓦将游戏置于Paidia-Ludus这一连续光谱中,并强调其中Paidia蕴含的自由与愉悦玩耍本能。而在电子游戏商品日趋普遍的现实里,凯洛瓦意义上的Paidia向度日趋消逝直至蜕化为诸如游戏化的修辞,并同时成为消费-劳动过程中的驱动话语:其一,电子游戏作为数字资本主义的理想商品,虽然声称以玩家的愉悦玩耍体验为目的,但是其消费设计却并非意在形成一个玩耍本能的释放空间,而是构成一个与玩耍本能有些许交错但本质在于使欲望增殖并将其变现的控制场域;其二,电子游戏商品因其具备双重“确定的可能性”,即其作为商品在被购买前所具备的确定的可能性与其作为电子游戏本身所具备的确定的可能性,成为无摩擦资本主义视域下的消费润滑剂,Paidia蕴含的自由与愉悦玩耍内涵在此蜕化为鲍德里亚意义上泛化的“娱乐道德”;其三,游戏化概念基于电子游戏商品普遍化的现实被抽象出来,并流行于营销、教育、培训等领域,不仅反过来重塑了一般消费品的营销逻辑,更为一种精巧的管理与组织技术作了掩护,无批判地接受这种游戏化修辞,反而削弱了Paidia向度下自由与愉悦的游戏所蕴含的创造性力量。

变事是汉代传世与出土文献中的习用语,指非常之事或变事书——章奏文书的一种。围绕变事,文献中的相关用语所指各有差异:言变事指报告非常之事,言变事者和言变事书分别指报告非常之事的人和章奏文书;上变事指上报非常之事给皇帝,其比上言变事更为常见,是变事和言变事进入上报程序的体现,并衍生出系列规定,即上变事制度。从法制史视角看,出土文献比传世文献展现更多汉代上变事制度的形成轨迹和例证,提供了汉代诏书转化为律令的直接证据,透露出汉代律令“因事立法”的特点,也有助于了解散佚的《变事令》。

作为现存最早的蒲台县志,万历《蒲台志》是邑人王尔彦传承地方文献的使命感和知县李时芳自觉修志责任感的产物。它的修纂跨越26年,经历从私修到官修的性质转变。是志刊行后流传近百年,在此后60多年中的某个时间点“失传”;其核心读者群包括上级部门的官员、知县的友人和继任者,以及了解当地情况的士人。作为私人修纂而后得到官方支持的方志,是志确立了蒲台县志的结构,在人口、马政和乡约等方面记录蒲台县历史的同时反映了明朝历史的特点,但也存在条目归属有待优化、部分内容有待考订和收录条目失于审慎等不足之处。

agricultural Sciences in China 2009年第5期8卷 556-563页

This study was designed to analyze the changes of phytohormone concentrations, calcium fraction, and the activities of degrading enzymes during calcium-inhibited and ethyleneglycol-bis-（β-aminoethyl ether）N, N＇-tetraacetic acid （EGTA）-induced abscission of tomato pedicel explants. Added calcium caused an increase in the total calcium content within the abscission zone and produced a corresponding reduction （20%） in pedicel explant abscission. As expected, EGTA treatment produced the opposite effect and resulted in a decrease in the total calcium content, while accelerating abscission of pedicel explants. Hormone analysis revealed that indole-3-acetic acid （IAA） concentrations in the abscission zone first decreased and then increased before the occurrence of abscission in all treatments, with the greatest effect produced by addition of EGTA. Similarly, abscisic acid （ABA）, and gibberellin （GA1＋3） concentrations, and ethylene production were elevated in the abscission zone during the first 16 h before abscission when explants imbibed EGTA. With calcium treatment, the concentrations of ABA, ethylene, and GA1＋3 also increased in pedicels throughout the first 16 h following exposure, but the increase was slower and less dramatic than with EGTA. Both cellulase and polygalacturonase were induced in the explants during abscission and the activities were also strengthened by treatment with EGTA. Calciumtreated explants produced lower hydrolysing enzyme activities than controls throughout abscission. Calcium played a role of mediating hormone balance and degrading enzymes activities and affected on abscission.

通过室内试验模拟不同底质条件,研究了苦草根部细菌群落的组装模式和功能变化。结果表明:底质条件的改变对苦草根际细菌群落产生了显著影响(p=0.003),特别是在添加有机质和植物根际促生菌的底质条件下;尽管根际细菌群落与根内生菌群落存在较强联系,但根内生菌群落组装过程拥有更高的确定性,而根际细菌群落组装过程更易受到植物宿主以外叠加的环境因素影响;功能预测结果表明在添加有机质和植物根际促生菌的条件下,苦草根部细菌群落拥有更高的代谢活性,更有利于有益细菌群落在苦草根部的富集。
