This study examines preservation of microfossils identified as introduced Ipomoea batatas in soils from northern New Zealand. Starch grains and xylem cells showed highly variable preservation, from good to extremely poor. For starch grains, the latter included brown-staining, expansion and distortion of the grain and vacuole, loss of the Maltese cross, pitting, cracking, fragmentation and disintegration. Degraded xylem showed similar brown-staining, occasional cracking, cross-wise fragmentation, with wall pits becoming progressively less visible or showing distortion, expansion and coalescence.  相似文献

Scholars have been studying the concept of public engagement and its role in the policy process for some time. Scholars have argued that understanding the interests and motivations of the public and engaging them in the decision‐making process can lead to better policy designs and, ultimately, better policy outcomes. However, studies of public engagement often assume that people have a desire to get involved in the policy process. This paper tests this key assumption using the case of nuclear facility siting in the United States to ask: what factors influence an individual's stated willingness to want to engage in the policy process? Using data from a national web survey fielded in 2013, we ask the public if and to what extent they would likely engage in the siting process if given the opportunity. Findings indicate that the likelihood of engagement varies rather substantially across individuals. We find that an individual's cultural belief system and existing level of political activity account for some of this variation. These findings suggest that public engagement programs may vary across groups and communities. In other words, the prospects of engagement are likely to appeal to some members of the population and not others.  相似文献

The Iron Age settlements of northern Cameroon were dispersed across the landscape, taking advantage of different eco-climatic zones to exploit a variety of natural resources. Situated at the interface of the upper and lower terraces of the Benue River, mound sites in the area around Garoua have occupation histories spanning multiple centuries. The site of Langui-Tchéboua displays evidence for rapid accumulation of sediments approximately 700 years ago, which may have been a deliberate construction strategy that would have allowed the site’s inhabitants to exploit resources in both floodplain and dryland contexts. The combined use of multiple dating methods and micromorphology provide novel insights into both the mechanisms of anthropogenic landscape change and possible motivations governing those choices.  相似文献

This paper investigates the social and cultural geographies of large-scale individual giving in supporting the work of ‘elite’ international universities. With public funding of higher education in general decline, universities in countries of the global North are increasingly seeking funding from alternative sources, including private philanthropy. Although scholarly work has examined corporate and foundational giving to Higher Education Institutions (HEIs), there has been little enquiry into how donations from wealthy individuals are represented by universities in their official literature. Publications such as annual reports, giving reports and campaign reports are used strategically by HEIs to project a global image. We examine the official literature of 50 elite HEIs located across the globe, uncovering new discourses into the cross-cultural reach of universities. We draw attention to complex social and cultural relations between HEIs and philanthropists, describing their encounters with reference to debates on personal mobilities, world-making and global and social inequalities. We conclude by highlighting the implications for theoretical work on ‘strategic philanthropy’ and on the transformative nature of HEIs as global centres of knowledge.  相似文献

In the face of the reemerging threat of preventable diseases and the simultaneous vaccine risk controversy, what explains variations in Americans’ policy preferences regarding childhood vaccinations? Using original data from a recent nationwide Internet survey of 1,213 American adults, this research seeks to explain differing public opinions on childhood vaccination policies and related issues of governance. As Mary Douglas and Aaron Wildavsky's grid‐group cultural theory of policy preference formation suggests, cultural biases have a significant impact on the formation of preferences toward various vaccination policies. Hierarchs are in support of mandatory vaccination, oppose religious and philosophical exemption, and believe the government should preside over vaccination‐related decisions. Fatalists strike a bold contrast in their opposition to mandatory vaccination policy and support for religious and philosophical exemptions and the role of parents in deciding on vaccinations. Falling between hierarchs and fatalists, egalitarian support for vaccinations is stronger than individualists‘.  相似文献

This article focuses on Mark Latham's views on equality. Latham's emphasis on education and on overcoming suburban, spatial inequality draws on the Whitlamite tradition. However, his work also draws on neoliberal influences and on arguments regarding the impact of the information economy. Both these influences have contributed to a move away from more traditional Labor and social‐democratic views on class, racial and gender inequality. This article considers Latham's relationship with traditional Labor ideology as well as with Third Way politics. Latham's arguments regarding the role of elites and the implications that this has for his understandings of the city, capitalism and diverse forms of inequality are also addressed. Latham's earlier views still influence his speeches and electoral strategy as Labor Leader.  相似文献
