First, it reconstructs the argument about the legal provision structure aroused by Analytical Jurisprudence. Austin deemed that the order rule is the main part of the provision structure, but Kelson thought that the punishment rule is the main part of the provision structure. Hart believed that the provision structure should have diverse forms, but the punishment rule is by no means necessary to any provision.

首先，重构了分析实证主义法学有关法律规范结构理论的主要争论：奥斯丁认为命令性规则是法律规范结构的主要部分，而凯尔森则认为规定制裁的规则是规范结构的主要规则，哈特则认为，法律规范应该具有多样形式，但规定制裁的规则并非对任何规范都是必要的。

The analytical approach/tool of MultipleScale Integrated Assessment of Societal Metabolism, proposed by Mario Giampietro,Kozo Mayumi, et al., based on the congruence among resource "Human Activities", resource "Exosomatic Energy Flows", and "Added Value Flows" in the hierarchical socioeconomic systems, using, in an integrated way, incommensurable variables referring to nonequivalent descriptive domains(coming from various scientific disciplines) and data gathered at distinct hierarchical levels, addresses the various relevant dimensions of societal development and sustainability.
