Text analysis, web scraping, and other computational techniques enable policy network researchers to efficiently obtain objective measures of network connections. However, the extent to which these observational methods differ from traditional survey instrument‐based measures remains an open question. Focusing on a large regional policy network of 221 organizations, this study compares a measure of collaboration generated via survey instrument to two different measures based upon internet hyperlinks and Twitter interactions between network actors. We address two questions: (1) To what extent do objective network measures based upon observed online interactions and subjective measures based upon self‐reported relationships reveal the same inter‐organizational partnerships and structural network dynamics? and (2) How useful are online network measures for supplementing survey‐based network measures? We find a significant, but substantively small, correlation between survey‐based measures and online interactions. Thus, online network measures may complement survey‐based measures, but likely reflect different aspects of the overall policy network. We conclude by discussing the potential for multiplex measures of policy networks that draw upon multiple measures to more fully understand policy network landscapes. These results bridge and help to contextualize prior work on policy network measures and virtual policy networks within the broader context of complex governance systems.  相似文献

Epipalaeolithic hunter-gatherer communities in the Southern Levant exhibit numerous complex trends that suggest that the transition to the Neolithic was patchy and protracted. This paper explores the changing nature of occupation at the Epipalaeolithic site Kharaneh IV, Jordan, through an in-depth analysis of the lithic and faunal assemblages. Focusing on the analysis of a single deep sounding (unit AS42), we address how Kharaneh IV occupations link to the local landscape and environmental changes. As an aggregation site, Kharaneh IV represents an interesting locale to explore the changing nature of aggregation and social cohesion prior to the origins of agriculture, as well as changes in technology and subsistence between the Early and Middle Epipalaeolithic. We explore the tempo and nature of transition from one archaeological culture to the next through changes in technology and how this reflects the people making and using tools, to understand how foragers adapted to a changing landscape.  相似文献

Focused around a 1929 publication of accounts of Ngarrindjeri history and culture provided by prisoner of war, Roland Carter, in Wünsdorf, Germany in 1918, to jurist and ethnographer, Leonhard Adam, this article examines the function of social connection, and dislocation, in the preservation of cultural heritage. In 1940, Adam was interned in Australia as an enemy alien. In 1947 the men briefly renewed contact, but, it seems, never met. This story of friendship and of shared interests demonstrates the labile and resilient nature of social connection as a mechanism in cultural heritage preservation.  相似文献

This article seeks to explore the European debate on commercial nobility at the beginning of the Seven Years War in the light of the intense reform debates over French absolutism in the 1730s and 1740s and Montesquieu's rigid refutation of noble trade in The Spirit of the Laws (1748). In early 1756, Montesquieu's position against noble trade had come under severe attack by Gabriel François Coyer's Noblesse Commerçante. Claiming that the royal absolutist system had transformed the nobles into an idle class without any political, economic, or military function that stood in sharp contrast to the dynamism of modern commercial society, Coyer perceived noble enterprises in maritime, wholesale, and even retail trade as a necessary means to help France compete with commercially more advanced states such as England and Holland. Coyer's pamphlet roused heated controversies in Paris and beyond and soon engaged the leading minds of the time in debates over the actual and desired role of the hereditary aristocracy in monarchies. Coyer's strongest opponents, like the Chevalier d’Arc, vehemently defended Montesquieu's contention that the upkeep of the non-commercial status of the nobility was a political necessity. Yet they, too, conceded that the nobility had to undergo severe reforms not to hamper France's military standing and future economic success. The article finally turns to Johann Heinrich Gottlob von Justi, the most interesting commentator on the debate in Germany, who, by October 1756, had translated Coyer's and d’Arc's texts into German and written an own treatise on the same issue. Justi's pamphlet reveals that his political theory was deeply shaped by the debate and thus disproves the long-held assumption in the literature that German cameralism, with Justi as its main representative, was an allegedly isolated current of thought that neither received significant external influences, nor exerted any considerable impact beyond the boundaries of the Germanic world.  相似文献

This article explores the complex and contested intellectual relationship between two of the key thinkers of the Early Enlightenment: Spinoza and Bayle. The key issue of contention between them is not, it is argued, the question of the existence and nature of God, but their profoundly contrasting visions of the nature of philosophy as a politically emancipatory practice. The article analyzes Bayle's rejection of Spinoza's systemic certainty, and the significance of this rejection in relation to Bayle's own anti-systemic philosophy of openness and incompletion. This contrast between Bayle and Spinoza is deployed to clarify the interpretation of Bayle's theory of toleration and of his late writings.  相似文献

Over the past five years there has been a remarkable resurgence in oil and gas exploration in the North American Arctic. From completed disinterest only a half a decade ago the region has attracted billions of dollars in new investments from a host of different international oil companies. Unlike the past booms in the region, which inevitably ended in busts, this new wave of development is different. This article examines the changes in both the Arctic itself as well as the global energy environment and concludes that the North American Arctic will see slow bust sustained development over the coming decades, ultimately becoming one of the last great oil producing regions in the world.  相似文献

A Global Database of Antiquities (GDA) could foster compromise among the stakeholders in cultural property debates and contribute to the eradication of the illicit market for ancient artifacts. The technical feasibility of such a database is discussed, as are the motivations for both ‘nationalists’ and ‘internationalists.’ The issue of orphaned objects will be addressed by suggesting that those for which a source country cannot make a claim are granted amnesty from future attempts at repatriation, and an accompanying legal framework for regulating a GDA is proposed that draws on the precedent of mutually beneficial repatriation agreements.  相似文献
