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

ABSTRACT

This paper reports on results of nonlinear analyses performed within the RINTC project on an RC building isolated with different systems (High Damping Rubber Bearings, High Damping Rubber Bearings and Flat Sliding Bearings, Friction Pendulum System) and designed according to the Italian design code. The seismic response has been evaluated under different seismic input levels of two sites with different hazard and by considering two Limit States: Global Collapse and Usability-Preventing Damage. The influence of seismic stoppers and modelling uncertainties is also evaluated. Results permit to compute the implicit collapse risk and to identify critical aspects of current design procedures.  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

The city of Herculaneum (Naples, southern Italy), buried by the volcanic eruption of Mount Somma-Vesuvius in 79 ad, is a key site for understanding the timber economy during the Roman period. In this paper, the results of charcoal analysis of different building element types are presented. Beams, joists, poles, planks and door and window frames were investigated allowing us a view of which timber the Romans preferred for building in this area. We also fit the taxonomic results into the reconstruction of the ancient Campanian landscape, and finally, we discuss the knowledge that the Romans had about the technological properties of the wood that they used for building and the possible selection criteria that they followed in choosing them. Coniferous timber is the preferred material for building purposes. Abies alba is especially used, this fact confirming its stronger presence in southern Italian woods during the past and suggesting that its decline is mainly due to human overexploitation. The large presence of Cupressus sempervirens, selectively used for the production of poles, confirms that this tree was cultivated in plantations for timber production in the Vesuvius area. Furthermore, it might indicate that cypress could have been present as a natural tree in the local vegetation, suggesting a forest type that nowadays almost completely disappeared from this area and from the entire Italy. The findings of Juglans regia, Pinus pinea and Olea europaea, typical elements of the Mediterranean cultural landscape, show that their use was not limited to fruit production and that Romans also appreciated their timber. Beside these local resources, the presence of Picea abies and Picea/Larix indicates the importation of timber from northerly regions, probably the northern Apennines and the Alps.  相似文献

博物馆影响力的程度制约着博物馆社会价值实现充分与否,因而博物馆影响力问题处于博物馆理论体系的核心位置。博物馆影响力的产生基于博物馆物质资源、无形资源与现代媒介的应用;其特点体现为复杂性、非权力性与缓释性;其影响涉及公众、社会与同行业三个层面。而对博物馆影响力理论研究的最终目的在于寻求提升之路径。  相似文献

Abstract

The 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

Scholars of space usually neglect the history of travesti populations in Latin America. It is misrepresented not only by disciplinary blind spots but also by global narratives concerned with rehabilitating queer subjects within homonormative projects. Analyzing neoliberal narratives that delink conflicts about racialization and sexuality in Argentina, this article makes room to decolonize the study of travesti experience and embodiment in Buenos Aires's red zone. It examines a network of racialized travestis and their spatial practices, including their migration from the Andean northwest to the sex-work circuits of Buenos Aires. Finally, this article introduces the notion of sideways relationality to account for the cultural and spatial labor that racialized travestis perform at the oppositional margins of homonormative reflexivity.  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

Examining histological sections obtained from human bones from Iron Age archaeological excavations (about third to fifth century BC , Alfedena and Sulmona, central Italy), the authors show the presence of an amorphous, afibrillary substance inside the osseous canaliculus in decalcified sections. This substance has shown unusual chromaffinity to staining using the Schmorl method with thionine and phosphowolframic acid. It is probably formed by acid mucopolysaccharides obtained from a transitory betametachromasia with toluidine blue staining at neutral pH. This metachromasia persists after digestion in bacterial collagenesis, but disappears after digestion in bovine testicular jaluronidasis. These reactions indicate that the endocanalicular substance may represent well-kept remains of a Rouget-Neumann sheath, which surrounds cytoplasmic extensions of osteocytes.  相似文献
