GMM tests for the Katz family of distributions

Generalized method of moments (GMM) is used to develop tests for discriminating discrete distributions among the two-parameter family of Katz distributions. Relationships involving moments are exploited to obtain identifying and over-identifying restrictions. The asymptotic relative efficiencies of tests based on GMM are analyzed using the local power approach and the approximate Bahadur efficiency. The paper also gives results of Monte Carlo experiments designed to check the validity of the theoretical findings and to shed light on the small sample properties of the proposed tests. Extensions of the results to compound Poisson alternative hypotheses are discussed.     

黑龙江（汉族）民歌衍变过程探析——对黑龙江、河北（汉族）民歌的比较

黑龙江汉族民歌的衍变历经了数百年的岁月沧桑，它与民族迁徙、人口变迁以及文化传统等存在着极为密切的联系。通过对黑龙江民歌与河北、山东、河南、山西民歌进行比较，表明黑龙江民歌与河北民歌之间存在着较近的亲缘关系。因此，文章试图在对较有代表性的几首黑龙江与河北民歌比较研究的基础上进一步探究黑龙江民歌衍变的影响因素。     

中国农村妇女问题研究综述

随着党中央对三农问题的重视,中国农村妇女问题逐渐凸现出来。对近二十年的中国农村妇女研究重新进行阶段划分,并对中国农村妇女研究所涉及的性别与劳动就业分工,农业女性化问题,农村妇女家庭地位及其变化,农村妇女科学文化素质及培训,农村女性劳动力流动及影响因素,农村妇女与贫困,农村妇女与人口再生产,农村妇女与资源、环境和持续发展,农村妇女参政议政等问题,进行多角度的分析说明,从中总结出经验和不足。农村妇女发展要联系农村实际,要针对多方面因素考虑农村妇女发展与农村诸要素之间的关系。农村妇女研究要采取定量与定性相结合的分析方法,从不同地域、不同环境入手分析当地农村妇女的实际情况,以便在今后的研究中得以借鉴。     

Generations,Identities, and the Collective Memory of Che Guevara1

Has the image of Che Guevara lost its power to evoke radical politics in the face of pervasive commodification? The commercialization of this 1960s political icon has called into question the power of the market to shape collective memories. Meanwhile, antisystemic movements of the left continue to erect his image at protest events. In light of this contest over how Che Guevara is remembered, we investigate, using data from a survey of Spanish citizens, who is most likely to recall him. We find qualified support for the theory of generational imprinting—Che is more often recalled by those generations who saw him rise to prominence during their formative years, although prominent as a collective symbol rather than as a living person. Our results also corroborate the claim that historical figures or events are more salient for, and therefore more likely to be remembered by, some subgenerational units than others. Thus, although the younger generations are in general more likely than their elders to recall Che, he is most frequently remembered by the highly educated leftists who espouse postmaterialist and posttraditionalist values and identify more with their local regions than with the nation of Spain. These patterns suggest that, in contrast to the dire predictions of mass culture theorists, the memory of Che Guevara has become increasingly tied to markers of social, ethnic‐regional, and political identity.

基于复杂适应系统的作战理论哲学反思

传统的作战理论与方法已经不能适应像现代信息化战争系统这类充满“活”的个体和变化因素的复杂系统，需要进行理论创新。而复杂适应系统理论是当代系统科学的一个新发展。有望成为创新作战理论的突破口。本文在分析比较作战系统的基础上，认为作战系统实质是复杂的适应系统，作战系统内的作战双方都力图以增强自身的适应性和复杂性，削弱对方的适应性和复杂性取得作战的胜利。
