In this work, we apply a systemic approach to the analysis of a particular geographic territory, the industrial district. We are particularly interested in analysing the interaction between the productive-technological environment and the scientific environment by an examination of research contracts and patents. Our analysis shows that R&D activity in the Spanish ceramic tile District Innovation System was mainly conducted by suppliers. Final producers’ innovation efforts were related to non-technological aspects and differentiation. 相似文献

What did peasants discuss at party meetings? Were they mobilized by ethnic politics or indifferent to them altogether? The end of the First World War brought about universal male suffrage in much of Europe, and with it the process of mass politics began. The concept of national indifference is important in understanding interwar politics, because this period is often studied teleologically with attention focused on extremism and nationalism as the primary mobilizing issueAgrarian movements have been under-researched, and when Agrarians have been studied, it has been through the prism of elite politics. This comparative paper seeks to redress this omission by looking at grassroots rural politics. The interwar countryside was marked by profound political, economic and social transformation but also in terms of what Robert Paxton has described as the ‘triple crisis of the countryside’ – worsening economic conditions, the declining status of the countryside and inadequate political representation. The paper will explore how reform and crisis impacted how agrarian politics functioned at a local level by asymmetrically comparing cases from Romania, Poland and Ireland, with the final case helping to contextualize Eastern Europe within the wider European experience This paper argues that the rural population was mobilized, but primarily in the context of local issues rather than national ethno-political questions. Local party organization was, to paraphrase James C Scott, the site ‘of an exchange of small arms fire’ in rural class conflict, as questions regarding the control of public space, generational conflict and power within the village mobilized peasants. Thus, I argue that it was the underlying socio-economic issues that mobilized the rural population, not nationalism. The dynamics of these conflicts were shaped by local economic, political and social power dynamics, and by using indifference as a concept, we can look more deeply at interwar politics from a grassroots perspective and develop a more nuanced understanding of local, national and European politics. 相似文献

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity. 相似文献

We investigated the contribution of freshwater resources to the diet of seven Late Mesolithic hunter-gatherers (ca. 5300–7000 BC) from Northern France and Luxembourg using stable isotope ratios. In addition to the carbon and nitrogen stable isotope ratios (δ13C, δ15N), we explored the potential of the sulphur isotopic ratios (δ34S) to detect and quantify the proportion of protein derived from aquatic foodstuff. In only two sites, animal remains from an associated settlement were available and subsequently examined to decipher the isotopic differential between terrestrial and freshwater resources. The quantification of their relative contribution was simulated using a Bayesian mixing model. The measurements revealed a significant overlap in δ13C values between freshwater and terrestrial resources and a large range of δ15N values for each food category. The δ34S values of the aquatic and terrestrial animals were clearly distinct at the settlement in the Seine valley, while the results on fish from Belgium demonstrated a possible overlap in δ34S values between freshwater and terrestrial resources. Local freshwater ecosystem likely contributed to ca. 30–40 % of the protein in the diet of the individuals found in the Seine settlement. Out of this context, the isotopic signature and thus contribution of the available aquatic foods was difficult to assess. Another potential source of dietary protein is wild boar. Depending on the local context, collagen δ34S values may contribute to better assessment of the relative contribution of freshwater and terrestrial resources. 相似文献

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the PN+1DG‐PNDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated. 相似文献

This article traces the pivotal role that ideas about “youth” and “generationhood” played in Vladimir Jabotinsky's political strategy as leader of the Union of Revisionist Zionists and its youth movement, Brit Yosef Trumpeldor (Betar). During the leadership struggle within the movement between 1931 and 1933, Jabotinsky believed that he could draw upon debates sweeping across Europe about the nature of youth, their role in politics, and the challenges of “generational conflict” in order to convince his followers that his increasingly authoritarian behavior was the only mode of leadership available to Zionist leaders in the 1930s. The article demonstrates that Jabotinsky's deliberately ambiguous and provocative constructions of “youth” and “generationhood” within the movement's party literature and in articles addressed to the Polish Jewish public, as well as the innovative ways in which he delimited “youth” from “adult” in his movement's regulations, allowed him to further embrace authoritarian measures within the movement without publicly abandoning his claim to be a firm proponent of democracy. 相似文献

Latent trajectory models for space‐time analysis: An application in deciphering spatial panel data 下载免费PDF全文

This article introduces latent trajectory models (LTMs), an approach often employed in social sciences to handle longitudinal data, to the arena of GIScience, particularly space‐time analysis. Using the space‐time data collected at county level for the whole United States through webpage search on the keyword “climate change,” we show that LTMs, when combined with eigenvector filtering of spatial dependence in data, are very useful in unveiling temporal trends hidden in such data: the webpage‐data derived popularity measure for climate change has been increasing from December 2011 to March 2013, but the increase rate has been slowing down. In addition, LTMs help reveal potential mechanisms behind observed space‐time trajectories through linking the webpage‐data derived popularity measure about climate change to a set of socio‐demographic covariates. Our analysis shows that controlling for population density, greater drought exposure, higher percent of people who are 16 years old or above, and higher household income are positively predictive of the trajectory slopes. Higher percentages of Republicans and number of hot days in summer are negatively related to the trajectory slopes. Implications of these results are examined, concluding with consideration of the potential utility of LTMs in space‐time analysis and more generally in GIScience. 相似文献
