Culture and Rights after Culture and Rights

Building on a critical, theoretical approach outlined in Culture and Rights: Anthropological Perspectives (Cowan et al. 2001a), I posit rights processes as complex and contradictory: Both enabling and constraining, they produce new subjectivities and social relations and entail unintended consequences. To encourage interdisciplinary engagement on these themes, I explore selected texts that consider the relationship between culture and rights, addressing two literatures: (1) debates on culture, rights, and recognition in the context of multiculturalism among political philosophers and (2) an emerging literature by anthropologists, feminists, critical legal scholars, and engaged practitioners analyzing empirical cases. Although political philosophers elucidate ethical implications and clarify political projects, an outmoded arsenal of theoretical concepts of "culture,""society," and "the individual" has hampered their debates. When accounts are both theoretically informed and empirically grounded, contradictions, ambiguities, and impasses of culture and rights are more fully explored and the liberal model of rights and multiculturalism is more open to interrogation.     

Culture evolves

Culture pervades human lives and has allowed our species to create niches all around the world and its oceans, in ways quite unlike any other primate. Indeed, our cultural nature appears so distinctive that it is often thought to separate humanity from the rest of nature and the Darwinian forces that shape it. A contrary view arises through the recent discoveries of a diverse range of disciplines, here brought together to illustrate the scope of a burgeoning field of cultural evolution and to facilitate cross-disciplinary fertilization. Each approach emphasizes important linkages between culture and evolutionary biology rather than quarantining one from the other. Recent studies reveal that processes important in cultural transmission are more widespread and significant across the animal kingdom than earlier recognized, with important implications for evolutionary theory. Recent archaeological discoveries have pushed back the origins of human culture to much more ancient times than traditionally thought. These developments suggest previously unidentified continuities between animal and human culture. A third new array of discoveries concerns the later diversification of human cultures, where the operations of Darwinian-like processes are identified, in part, through scientific methods borrowed from biology. Finally, surprising discoveries have been made about the imprint of cultural evolution in the predispositions of human minds for cultural transmission.

红枫增殖生长培养基配方研究

目的:研究红枫组织培养中增殖阶段的培养基,以期筛选出最适增殖培养基配方,为最终建立红枫无毒快繁体系奠定基础。方法:以MS培养基为基本培养基,附加不同浓度的CPPU和6-BA,并以食用白砂糖代替分析纯蔗糖,对红枫进行增殖培养,比较生长状况。结果:CPPU和6-BA均能促进红枫单芽茎段的腋芽增殖,其中以CPPU的效果较好。结论:最适增殖培养基为(MS,30g/L蔗糖,6.5g/L琼脂,CPPU0.3mg/L,IBA0.05mg/L),可以用食用白砂糖代替分析纯蔗糖对腋芽进行增殖培养。
