There has been an impressive stride in the research on policy feedback effects on mass publics over recent years. However, we lack systematic evidence on how large such policy feedback effects are in the literature. This article provides a review of 65 published studies and quantifies the findings and key themes in the policy feedback literature. The results show a great degree of heterogeneity in the domains and outcomes being studied and in the effects of policies on the public. In line with the findings from narrative reviews, feedback effects are greater for outcomes related to political participation and engagement. Last, the review sheds light on important theoretical and methodological limitations to be addressed in future research.  相似文献

The concept of the Daily Urban System (DUS) has gained relevance over the past decades as the entity to examine and explain the functionality of the urban landscape. Daily Urban Systems are usually defined and measured by the strength of commuter or shopper flows between the nodes of the system. It is important to realize that these Daily Urban Systems are the accumulated pattern of individuals making frequent, recurring trips to other localities than their own. Understanding the microeconomic decisions behind these spatial interactions will help in assessing the functional and spatial structure of DUS. In this paper is explored how, based on Dutch empirical data, the individual household’s spatial interactions shape the daily urban system and how the destination of these interactions correlates with personal and spatial variables and motives for interaction. The results show that the occurrence of non-local spatial interactions can be explained by the size-based Christallerian hierarchy of the localities of residence, but that it is the regional population – or market potential – that explains and moderates the sorting of households and the intensity and direction of their spatial interactions in the DUS, matching agglomeration theory.  相似文献

Historical evidence of aeolian activity in the outer coastal zone of Jæren, southwest Norway, is presented. Meteorological factors such as wind force and wind direction are discussed. Special attention is devoted to meteorological factors causing drought (evaporation and precipitation) as a necessary condition for the occurrence of sand drift. Several aeolian periods after 6000 BP have been identified in the sediments along the coast of Jæren. It is suggested that the changes in the aeolian activity observed have arisen from changes in the environmental state, such as lowering sea level, climatic variation and environmental stress caused by man's interference in connection with increasing agricultural activity (forest clearing, cultivation and so on).  相似文献

In this article, the hypotheses put forward in ‘A Theoretical Approach’ in Volume 1 of this Journal are tested. An account is first given of the additional settlements and hoards which were treated in the computer. The combined material consists of 17 units. The material is then evaluated and handled in a number of experiments in which various methods of arriving at special tendencies in the material are considered. Finally the various methods selected are discussed and the results summarised.  相似文献

This article, in analysing the Katangese secession of 1960–63, argues that it should be primarily understood not simply as the result of external machinations but, at least as importantly, as the initiative of indigenous Katangese political leaders. It charts the development of the Katangese national project among self-consciously ‘indigenous’ Katangese leaders, who responded to what they saw as an imposed and illegitimate Congolese nation-state by constructing a national imagery rooted in a mythico-historical reconstruction of a usable Katangese past. The article explains how this was utilised by the Katangese state during the secession to perform an ‘authentic’ Katangese national identity. In so doing, the article draws attention to the parallels between the Katangese nation-state project and attempts by post-colonial states to perform nationhood elsewhere in Africa.  相似文献

The defeat of Germany and Japan in 1945 required historians in both countries to reevaluate the past to make sense of national catastrophe. Sebastian Conrad's The Quest for the Lost Nation analyzes this process comparatively in the context of allied military occupation and the Cold War to reveal how historians in both countries coped with a discredited national history and gradually salvaged a national identity. He pays special attention to the role of social, discursive, and transnational contexts that shaped this process to highlight the different courses that the politics of the past took in postwar Germany and Japan. The picture that emerges of German and Japanese historiography and the respective attempts to come to terms with the past is at odds with the conventional narrative that usually praises West German historians and society for having come to terms with their dark past, as opposed to postwar Japan, which is usually regarded as having fallen short by comparison. There was in fact far more critical historiographical engagement with the past in Japan than in West Germany in the 1950s. Reasons for the divergent evolution of the politics of the past in Germany and Japan should not be sought in the peculiarities of postwar national history but rather in an entangled transnational context of defeat, occupation, and the Cold War, whose effects played out differently in each country. These conclusions and others reveal some of the opportunities and special challenges of comparative transnational history.  相似文献
