We have investigated the survival of PCR-amplifiable mitochondrial and nuclear DNA in a small number of modern and medieval bovine leather samples. The results of this preliminary investigation demonstrate that, while no nuclear DNA can be PCR-amplified from any of the specimens, mitochondrial DNA can be amplified from all samples. To investigate this contrasting pattern of DNA survival further, we have vegetable-tanned cow skin in our own laboratory, and directly assayed the survival of PCR-amplifiable mitochondrial and nuclear DNA at each step of the process. The results indicate that nuclear DNA is reduced to sub-amplifiable levels as a result of the tanning baths, whereas amplifiable mitochondrial DNA survives the complete process. Our results suggest that old and archaeological bovine leather may represent a useful source of genetic information, although this information will most likely be limited to that which can be gained from mitochondrial DNA. 相似文献

Under the leadership of Matteo Salvini, the Lega Nord has shifted away from its previous political identity as a voice for Italy’s north and has placed hostility towards the policies and institutions of the European Union (EU) at the heart of its rhetoric. Nowadays, the enemy is Rome no longer: it is Brussels, European institutions, and the threat to the national sovereignty posed by the EU. Borrowing from the Italian political philosopher Nicola Matteucci, we would describe Salvini’s Lega as a ‘populist insurgency’. That is to say, it is a populist party that marries the traditional populist evocation of the virtues of the people against the corrupt elites, with a pervasive glibness of analysis. 相似文献

Federalism often creates additional decisions for interest groups in determining how best to advocate for their policy recommendations in the legislative process. Should they focus their advocacy at the local, state, or national level of government? This article examines interest group behaviors in water quality policy in the Great Lakes region from 1960 to 2000. I evaluate the reasons for interest group decisions about which level of government to target, using historical analysis of Great Lakes water quality policy in the United States and Canada. The results of this analysis show that in many cases groups are influenced in their decision-making based on the level of government that has the greatest jurisdiction over the policy, supporting a neoinstitutional argument. 相似文献

In this article, I employ feminist and Marxist tools to expose the struggles over the constant plunder and expansion of global capitalism along Mexico's northern border, specifically in Ciudad Juárez, Chihuahua. In particular, I examine how an official politics – promoted by the Mexican and US governments – for forgetting the economic and social devastation of a transcontinental drug war contributes to the mechanisms for further exploiting the working poor. By combining a feminist focus on the daily struggle of social reproduction with a Marxist emphasis on accumulation by dispossession, I show how this official ‘forgetting’ segues with an international gentrification plan in downtown Ciudad Juárez that seeks to expand the rent gap by denying place, legitimacy and legal status to the working women and their families who have made this border city famous as a hub of global manufacturing. As such, I argue that the social struggles against the official forgetting are struggles against a violent political economy that generates value via a devaluation of the spaces of the working poor, even of the spaces of their literal existence. 相似文献

Many contemporary feminist research methods employed in the interest of realizing social justice advocate ‘listening’ to subordinated others, groups variously categorized and marginalized by gender, sexuality, race, age, and so on, in order to examine the sources and workings of knowledge construction and social power. Increasingly, feminist scholars are using group discussion or focus groups, in an effort to give subordinated others ‘a voice.’ Group discussions are seen as potentially empowering in exploring and enabling group members’ social agency and knowledge production while at the same time diminishing the unequal power relations between the researched and researcher. In this article, I argue that the attention given to ‘voices’ in group discussions (dis)misses meaning‐ful silences thereby limiting its political potential. There exists an ‘epistemological messiness’ inherent in a feminist group discussion method that makes it difficult to hear meaning‐ful silences. Through reflection on my own research into the spaces of adolescent Latina gender identities, this article offers some insights into this messiness and recommends that a feminist group discussion method be guided by a politics of voice which includes ‘silence within voice.’ 相似文献

The notion that women are ‘closer to nature’, naturally caring for land, water, forests and other aspects of the environment, has held powerful sway in certain development circles since the 1980s. Along with the rise in global environmental concern, ‘women, environment and development’ (WED) perspectives gained ground among many donor agencies and NGOs, complementing and sharing core assumptions with earlier‐established ‘women in development’ (WID) discourses. The materialist dimensions of WED were bolstered by fables about women's natural, cultural or ideological closeness to nature grounded in varieties of ecofeminist analysis. This proved a seductive mix for agencies wishing simultaneously to promote environmental protection and WID, as well as for certain forms of feminist activism and sisterhood‐construction, such as those around the 1992 United Nations Conference on Environment and Development. This contribution revisits these narratives and the politics of this strategic fix in the development of international environmentalism and explores the sustained critiques of these ecofeminist fables by feminist scholars and activists from the early 1990s onwards. It provides a critical review of the approach to gender and the environment in some current donor, NGO and other policy documents, which draw little from the feminist critiques of the 1990s. The author reflects on how, and for whom, women–nature links might have practical or strategic value today. 相似文献
