The concept of “advocacy coalitions” is the bedrock of the Advocacy Coalition Framework (ACF), one of the most established and successful approaches for understanding policy processes across the globe. This article revisits and sharpens the conceptual definition of advocacy coalitions. We summarize the lessons from its theoretical emphases under the ACF and specify its five attributes (policy actors, shared beliefs, coordination, resources, and stability). Through this specification, we identify the ideal coalition type and several coalition subtypes. We then clarify and make a distinction between how we think about coalitions as a concept and how we approach coalitions empirically. This article sharpens the lens for describing and explaining coalitions toward better observations, theorizing, and measurements. It ends with next steps for further deepening and broadening knowledge about advocacy coalitions. 相似文献

The French statesman Charles de Gaulle was, and remains, something of an enigma. A genuinely great man, at first glance, he seems to tower above mere humanity. In studying de Gaulle's biographies and writings, the statesman and military man eclipses the human being without leaving his human bearing wholly behind. De Gaulle himself emphasized the solitude and sadness that accompanied the burden of human greatness. Yet de Gaulle, the self-described “man of character,” “the born protector,” was also a loving husband, a not terribly demanding or severe father, a faithful Christian, and a French patriot. There were profound limits to his solitude and self-sufficiency. His austere magnanimity coincided with moderation, even benevolence. He loved his country, strove for greatness, and sacrificed something of his private happiness for the public good. He was a complex man and soul, and perhaps a conflicted one. 相似文献

We analyse the isotopic values (δ13C, δ15N) of the diet of pre-Columbian horticulturalist populations from tropical and subtropical areas of southeastern South America, belonging to the Guarani and Taquara archaeological units. The data indicate different trends in each one (T?=?4.21; P?=?0.0004), showing a mixed diet with maize consumption in the Guarani samples (δ13Cco?=??15.5?±?1.8‰; δ13Cap ?10.4?±?0.8‰) and a depleted one in the Taquara ones (δ13Cco ?18.2?±?1.7‰; δ13Cap ?11.9?±?0.9‰), with a significant internal dispersion in both populations. The first population has higher nitrogen values (δ15N 11.1?±?0.6‰) compared to the Taquara samples (δ15N 9.3?±?1‰), suggesting a more carnivorous diet. The recognition of these pre-Columbian mixed diets involves the identification of maize cultivation on the Atlantic side of the southernmost area of South America (Parana Delta, 34° SL). Through the analysis of δ18O we have identified two isotopic ecozones, the first along the Paraná River Valley, with an average value of δ18O ?3.7?±?0.5‰ (CV?=?13.5%; CI?=??3.83 / ?3.16), and the second one, located in the Planalto of southern Brazil (Araucaria Forest), with a mean value of δ18O ?1.5?±?0.3‰ (CV?=?16.5%; CI?=??1.69 / ?1.29). The isotopic data (δ13C, δ15N and δ18O) suggest human movements between these two ecozones. 相似文献

Spatial planning commonly adopts a diversity of functions and logics in contributing to the handling of growth and development. Being influenced by an array of contextual driving forces that result in specific institutional practices and policy agendas, spatial planning seems to be constantly reoriented in terms of its purposes and reasoning. This article sets out to explore the diverse orientations and roles that spatial planning has assumed in Denmark over a 50-year period. In doing so, the article examines the evolution of national planning policy by means of a multi-disciplinary framework comprising analytical concepts drawn from planning theory, state spatial theory and discourse analysis. Based on an in-depth study, the article then attempts to qualify, illustrate and synthesize the diverse roles that spatial planning has assumed in Denmark throughout that timeframe. The article concludes that spatial planning initially assumed a steering role, which has been either supplemented or substituted by balancing and/or strategic roles over the course of the past two decades. As a whole, this case is thought to contribute to current discussions regarding how spatial planning is shaped in different parts of Europe. 相似文献

Since Marshall (1890), it has been widely held in urban economic theory that cities insure workers against the risk of unemployment by offering a larger pool of potential jobs. Using a large administrative panel data set on workers displaced as a result of plant closures, we examine whether positive effects from a higher urban job density are offset by more intense competition between workers. When controlling for the sorting of workers between regions, we find robust evidence that the effect of job competition on unemployment duration exceeds that of job opportunities in absolute value. Our results put the idea of urban risk-sharing into perspective and provide an explanation for observed longer unemployment durations in cities. 相似文献
