The Narrative Policy Framework (NPF) suggests that narratives can be employed to define and contest policy problems. Yet, few NPF studies have explicitly addressed the narrative portrayal of problem intractability. What role do narratives play in a situation of uncertainty about the causes and solutions of the problem, when strong divergences regarding the values and interests of the policy actors exist? The article anchors the NPF to the literatures on problem definition and implementation to advance two propositions about (a) how differences in the use of narrative elements can be suggestive of the degree of problem (in-)tractability; and (b) whether other elements of tractability, namely the presence of a valid causal theory, are associated with the usage of narrative strategies. I test the propositions by analyzing media commentaries surrounding the implementation of European decisions to tackle a tree-killing epidemic in Italy. The findings suggest that narratives can helpfully illustrate the intractability inherent in the policy debate. However, narratives can also develop independently of factors that the implementation literature understands as conducive to lowering intractability, namely knowledge accumulation. The NPF may represent a promising alternative to understand policy implementation processes. 相似文献

The full release and circulation of excavation results often takes decades, thus slowing down progress in archaeology to a degree not in keeping with other scientific fields. The nonconformity of released data for digital processing also requires vast and costly data input and adaptation. Archaeology should face the cognitive challenges posed by digital environments, changing in scope and rhythm. We advocate the adoption of a synergy between recording techniques, field analytics, and a collaborative approach to create a new epistemological perspective, one in which research questions are constantly redefined through real-time, collaborative analysis of data as they are collected and/or searched for in an excavation. Since new questions are defined in science discourse after previous results have been disseminated and discussed within the scientific community, sharing evidence in remote with colleagues, both in the process of field collection and subsequent study, will be a key innovative feature, allowing a complex and real-time distant interaction with the scholarly community and leading to more rapid improvements in research agendas and queries. 相似文献

AbstractThe loss of agricultural land and its implications have been of great concern in the last decade. By undertaking a spatial analysis of the appropriation of agricultural land for urban use with an overlay of population and urban data, a focus on the consequences of certain regulations on the dynamics of land-use change is explored. This is achieved by integration of data inventories of agricultural land use for Portugal, and linking this information with CORINE Land Cover data as to assess change in the Algarve. An integrated assessment of agricultural land loss follows, undermined by the consequences of urban sprawl. In this sense, this paper expands on the currently existing decrees which provide support to sustainable development in the region while providing a qualitative assessment of future roles based on ethical values and economic efficiency and offering a feasible framework for policy-makers regarding the trends of urban/agricultural dichotomy in a planning and decision-making context. 相似文献

Regional strategic assets and the location strategies of emerging countries’ multinationals in Europe 总被引:1,自引:0,他引:1

This paper explores the location strategies of multinational enterprises (MNEs) from emerging countries (EMNEs) in search for regional strategic assets. The analysis is based on a systematic comparison between EMNEs and multinationals from advanced countries (AMNEs) in order to unveil similarities and differences between these two major sources of foreign investment into the regions of the European Union. The empirical results suggest that EMNEs follow a distinctive logic in their location strategies. They are attracted by the availability of technological competences only when their subsidiaries pursue more sophisticated and technology-intensive activities. Conversely, EMNEs share some behavioural similarities with AMNEs in their response to the spatial agglomeration of investments. 相似文献

Ancient iron tie-rods are handcrafted elements with large geometric irregularities, due to production techniques (they are shaped by hammering and linked by hot-forging) and corrosion processes. In common practice, their cross section (that is one of the main parameter to assess their strength) is manually measured on site with a manual caliber. By analyzing a set of detailed three-dimensional (3D) digital surveys of real ancient tie-rods, this study provide an evaluation of the errors made by in-situ manual geometric measurements. In particular, it shows that, in some cases, manual on-site survey is sufficiently reliable and has errors that fall below 10%. Moreover, it shows that when tie-rods have high corrosion levels in hidden zones (typically those close or within the retaining walls) the on-site survey of visible parts only may produce far greater errors that exceed 100%, leading to a strong overestimation of the cross-section of the tie. The ongoing study is a first step toward the definition of correction coefficients to be applied to the on-site manual measurements of ancient tie-rods, with the final aim to improve the reliability of structural analyses. 相似文献

This article explores the linguistic experiences of transnational soldiers, using the Spanish Civil War as a case study. It argues that communication difficulties provoked by linguistic diversity within the Republican war effort and particularly within the International Brigades, caused the high command to move from a utopian, internationalist policy to a more pragmatic approach. The article evaluates the role played by language intermediaries in this evolving policy and in the wider Republican war effort. Finally, it argues that soldiers grassroots experiences of language contact forged new linguistic forms which underlined a strong sense of shared purpose and identity. 相似文献

Practices of cultural production within a peripheral urban neighbourhood can contribute to foster the sense of place, community belonging and local collective action. Starting from a critical perspective on the interconnections between cultural practices and urban regeneration, and developing on the concept of place-making, the paper has two main purposes: to investigate the nature of embeddedness of these practices and explore the ways of self-organization of cultural actors and their relationships with public policies. The case study concerns ‘Barriera di Milano’, a large peripheral area in Turin (Italy), formerly one of the most industrialized zones of the city. Over the past few years, and particularly after the real-estate bubble burst of 2007–2008, in Barriera a lively concentration of initiatives of culture has been taking place, redefining the urban and social space. These initiatives seem to be innovative for many reasons: firstly, while demonstrating a peculiar but significant embeddedness in the neighbourhood, they are mostly self-generated; secondly, the institutional assets, the economic self-sufficiency and the low degree of connection among initiatives support new forms of citizenship and place-making based on a ‘not-for-profit entrepreneurship’. 相似文献
