Ecosystem‐based management (EBM) represents a comprehensive approach to better govern the environment that also illustrates the collaborative trend in policy and public administration. The need for stakeholder involvement and collaboration is strongly articulated, yet how and for what purposes collaboration would be effective remains largely untested. We address this gap by developing and evaluating a set of hypotheses specifying how certain patterns of collaborations among actors affect their joint ability to accomplish EBM. Content analyses of management plans drawn from five EBM planning processes in Sweden are combined with analyses of the collaborative networks through which these plans have been developed. Our results indicate that system thinking and the ability to integrate across different management phases are favored by collaborations between different kinds of actors, and by project leaders being centrally located in the networks. We also find that dense substructures of collaboration increase the level of specificity in the plans in regards to explicating constraints on human activities. Having many collaborative ties does however not enhance the overall level of specificity. Our results also show that different network characteristics can give rise to similar EBM outcomes. This observed equifinality suggests there is no single blueprint for well‐performing collaborative networks.  相似文献

The conservative, mainly Anglo-Saxon, critique of “social engineering” in Enlightenment thinking, which goes back to Edmund Burke and David Hume, among others, has recently resurfaced in the works of Michael Oakeshott, Roger Scruton, and Friedrich Hayek. This article focuses on their conservative critiques and more specifically on two common issues: the unintended negative consequences of political planning, and the institutions in civil society that act as a positive counterpart to this form of engineering.  相似文献

The aim of this paper is to explore the question: why is the archaeology of English historic landscapes apparently so provincial? Inevitably the response must be that matters are more complex. In this paper, I examine the work of W. G. Hoskins, the “father of English landscape history,” and draw attention to: the complex way in which landscape is embedded in nationalism; the relations between locale, province, and nation; and the way wider tensions, in particular of colonialism are embedded within Hoskins's own discourse. In conclusion, I examine ways in which this problematic continues to structure enquiry into the English landscape today and to inhibit a genuinely international and comparative approach to historic landscapes.  相似文献

Studies of old aerial photographs of the Bahrain burial mound fields have revealed that a small number of both Early Type (c. 2200–2050 BC) and Late Type (c. 2050–1750 BC) mounds are encircled by an outer ring wall, apparently marking out the mound as belonging to an elite. Four of these mounds have been excavated, and the results are presented. The geological differences between the Early Type and the Late Type mound landscapes are discussed.  相似文献

It is of vital importance to be able to sex identify cattle remains to understand the strategies and importance of cattle husbandry in an ancient society. This is usually done from osteoarchaeological assemblages and often relies on measurements of metapodials. The breadth measurement of the distal trochlea is considered an easy way to identify the sex. Bones from males appears to be easily distinguishable from female counterparts, although it has been complicated to find an external control for the morphological results. Here we investigate the reliability of these particular morphometrics for sex identifying cattle bones with molecular genetics. We use a sex discriminating single nucleotide polymorphism in the ZFXY gene and we apply it to DNA from the bones. To keep the fragment size short and suitable for ancient DNA we base the test on a SNP. The test confirms the osteological sex identification in all cases were DNA could be retrieved. This molecular method can also be used when no fragments suitable for osteological sex identification can be found or when the measurements are non-conclusive.  相似文献

This paper offers an introduction to the following papers, which represent the results of a round table at the Nordiska Historikermöte 2004 in Stockholm. It discusses the renewed interest in the study of diplomacy and international politics. This revival during the past few decades is sometimes not more than a reinvention of the old diplomatic history. However, it is also influenced by the history of ideas, as elaborated by Anglo‐American historians, and modern cultural sociology. The history of diplomacy seen from the perspective of cultural transfer offers new insights into early modern diplomacy based on a new reading of well‐known material.  相似文献
