理解全球化：基于“经济−社会−政治”体系共生演化视角的分析

20世纪80年代以来,一波超级全球化席卷全球。当今世界进入了百年未有之大变局,全球化陷入困境。应当如何理解当前的全球化困境？百年未有之大变局究竟变在何处？为此,可以从经济学、政治学、社会学与国际关系的综合视角,构建“经济−社会−政治”为一体的、动态演化的框架,以理解当今世界全球化的深层次矛盾。近一波全球化过程中全球经济力量与收入分配格局发生了变化,出现了发达经济体的经济停滞和新兴经济体的赶超,也导致了社会各阶层和不同社会群体的收入和财富差距发生巨变。全球化中全球经济基础的变化,即全球化中的全球经济力量格局变迁与收入分配恶化将对各国的经济和社会基础产生重大影响,进而影响上层建筑：国家的主导思想和意识形态。一个国家在国际关系和经济政策领域主导思想的演变,势必影响其对外战略和政策选择,进而影响本国的经济走向乃至全球化的历史进程。     

“东方经济”与中国乡村工业化的社会学机制—重访史国衡的个旧矿城研究

本文对“魁阁”社会学家史国衡1940年代在美访学期间的一部未刊稿《个旧矿城》进行了梳理与讨论。史国衡的个旧研究呈现了一个将产业、民情与治理相结合的综合进路,通过对个旧锡业兴衰的个案分析,揭示了传统“东方经济”模式的独特特征以及决定中国乡村工业化成败的社会学机制,同时也以个旧经验对现代化理论、人际关系学派等当时美国社会科学主流范式提出了反思。《个旧矿城》与另一部更为人所熟知的著作《昆厂劳工》共同构成了史国衡关于中国工业化研究的姊妹篇,“工业化的社会基础”是其中一以贯之的核心线索。对史国衡个旧矿城研究的“再发现”,有助于我们重新认识中国早期社会学的工业研究传统,同时也提示我们,当下的乡村工业化乃至乡村振兴仍然需要重视产业的社会基础,处理好经济转型与社会重组之间的辩证关系。

Isovaleroyl oxokadsurane, a novel dibenzocyclooctadiene lignan pos-sessing a spirobenzofuranoid skeleton was isolated from the stems of Kadsura coccinea.Its structure and relative configuration were determined by X-ray diffraction analysis.     

Circuit analysis of the compound quasi-optical power combiner

In 1991, we developed a new type of quasi-optical power combiner, called a compound quasi-optical power combiner, at Ka-band. In this paper, the circuit of such a compound quasi-optical power combiner is analysed. Its equivalent circuit model is proposed. The circuit equations, the balance condition, the injection locking and the stabilized condition of the compound quasi-optical power combiner are studed by the equivalent circuit model. As an example, a compound quasi-optical power combiner which consists of two single—cavity, two—device power combiners is analysed

ON A HYPER HILBERT TRANSFORM＊＊＊＊

The authors define the directional hyper Hilbert transform and give ita mixed norm estimate. The similar conclusions for the directional fractional integral of one dimension are also obtained in this paper. As an application of the above results, the authors give the Lp-boundedness for a class of the hyper singular integrals and the fractional integrals with variable kernel. Moreover, as another application of the above results, the authors prove the dimension free estimate for the hyper Riesz transform. This is an extension of the related result obtained by Stein.

Hilbert polynomials and Arveson's curvature invariant

We define and study Hilbert polynomials for certain holomorphic Hilbert spaces. We obtain several estimates for these polynomials and their coefficients. Our estimates inspire us to investigate the connection between the leading coefficients of Hilbert polynomials for invariant subspaces of the symmetric Fock space and Arveson's curvature invariant for coinvariant subspaces. We are able to obtain some formulas relating the curvature invariant with other invariants. In particular, we prove that Arveson's version of the Gauss-Bonnet-Chern formula is true when the invariant subspaces are generated by any polynomials.
