Ritual Demonstrations versus Reactive Protests: Participation Across Mobilizing Contexts in Mexico City

Using an innovative survey of protest participants and nonparticipants from five major street demonstrations in Mexico City in 2011 and 2012, this study tests the assumption that influences on protest participation vary across different types of events; namely, ritual demonstrations and reactive protests. The comparison is based on two assumptions: that these are two of the dominant forms of protest in contemporary Latin America, and that specifying the context for different types of social movement participation provides a better understanding of the individual mobilization process for groups seeking to defend their rights or gain new benefits. The comparative analyses reveal some crucial differences. Political interest and previous political experience are more influential in the decision to take part in reactive demonstrations. For ritual demonstrations, the decision to participate tends to be driven more by personal and organizational connections.     

行政协助的法律定位与控制

行政协助制度是行政程序法上的一个重要制度,但对这一制度的研究在我国却显得相对落后。随着行政职权的有限性和专业化与管理事项日益复杂化之间矛盾的不断加深,建立行政协助制度已成为解决现行管理体制弊端的必然要求。本文从对行政协助的法律定位入手,界定了行政协助的涵义、特征及与相似概念的区别,在此基础上进一步提出了从程序和责任两个方面对行政协助进行有效的法律控制。     

Fluorescence of a Natural Fluorophore as a Key to Improve Fingerprint Contrast Image

The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.     

公共政策与社会政策：一个系统论的比较

公共政策与社会政策是多学科的交叉研究领域,二者行动主体和作用客体是存在差异的。公共政策的主体更多的是社会权威机构,以政府和利益集团为核心进行政策制定和决策分析;社会政策的主体是以政府为先导,更加依靠非政府的民间组织发挥政策制定和实施的功能。公共政策偏重权威资源的调配,其制定和决策更多是从宏观层面、整体布局上解决问题;而社会政策由于有社会民间组织的积极参与,使得它有可能关注具体而微的个体生活困境,直接面向需要解决困难的社会成员。
