A region's technology potential can be developed in three ways: public finding; private investment (by business); and an intermediate area which ensures coherence between the public and private sectors, and which is mainly to be seen in interface structures between universities and business. After presenting these ways for Rhône‐Alpes, the paper introduces the regional policy to promote science and technology. According to French centralized political structure, the regional government acts as a lever. The region's innovation‐oriented policy, which should not be confused with a research‐oriented policy, has the impact of aiming all action at improving the technological environment of business, and at facilitating their economic development by integrating new technologies. Similarities between Rhône‐Alpes and Baden‐Würtemberg have led these two regions to cooperate increasingly in the fields of science and technology. The ‘four motor‐regions for Europe’ (with Lombardia and Catalonia) experiment in the field of new‐material investment cooperation could be useful if we think of the process aimed at strengthening integration in the European Community. 相似文献

Models of both primate and hunter-gatherer decision-making systems are developed and their relative abilities potentially to detect certain classes of spatial distributions within a standardized environment are compared. It is demonstrated that in situations where language facilitates the pooling of information between individuals within a hunter-gatherer group, the group minimally need only to pool information with one central decision maker in order potentially to recognize all possible spatial distributions within a limited environment. On this basis alone, we would theoretically expect the presence of one-leader groups to be a fairly ubiquitous phenomenon among hunter-gatherers. 相似文献

In the post-imperial world of sixth-century Gaul, the Church found itself competing for allegiance with strengthened local family groupings as well as royal households. In this milieu the fragmentation of power and the propensity for spoliation of church lands posed a severe problem for ecclesiastical survival. An answer might be found in a competing kindred structure: the family of the saint. Such an entity would have the benefit of building a support group for the Church that could cut across the existing family lines and thereby weaken their impact. As a voluntary association based on the celestial it would have the added benefit of being a familia everlasting, and endlessly elastic.The works of Gregory of Tours contain such an idea built around his patronus, St Martin. Gregory's preface to Book 5 of his History, and his frequent pleas against feuding, show his concern as to how the familia Sancti Martini could perform an annealing function for society, mitigate the more rebarbative elements of the feud, and leave the Church in a strengthened position in society. 相似文献

Same‐sex marriage has been one of the most widely discussed social issues in contemporary Australia for some time. In late 2017, after holding a contentious national postal survey that year, the Australia government introduced legislation allowing same‐sex couples to marry. This article draws on a major national lesbian and gay oral history project conducted in partnership with the National Library of Australia between 2012 and 2015, when discussions of same‐sex marriage were becoming increasingly widespread. It investigates the way interview subjects incorporated marriage into their narratives. In doing so, it highlights how understandings of marriage — both amongst lesbian and gay people and heterosexual people — have shifted and evolved over time. While some subjects saw marriage as a somewhat outdated, religious, and patriarchal concept, many others invested personal significance in the institution, arguing that allowing gay men and lesbians access to marriage would be a strong symbol of social progress and equality in a secular society. We conclude with one young interviewee who had managed to reconcile his faith with his sexuality and desire for marriage equality. 相似文献

Many studies have documented the benefits of urban agriculture, including increased food access, job creation, educational opportunities, and green space. A focus on its social benefits has fed an association of urban agriculture with social justice, yet there is a distinction between alleviating symptoms of injustice (such as disparate access to food or environmental amenities) and disrupting structures that underlie them. Despite its positive impacts, urban agriculture systems may reinforce inequities that practitioners and supporters aim to address. This paper reports findings from a 2‐year study of urban agriculture in New York City, which found race‐ and class‐based disparities among practitioners citywide. Using the lens of critical race theory, it argues that a failure to examine urban agriculture's role in either supporting or dismantling unjust structures may perpetuate an inequitable system. The paper concludes with recommendations for urban agriculture supporters and scholars to help advance social justice at structural levels. 相似文献
