Hierarchical accountability often proves insufficient to control street-level implementation, where complex, informal accountability relations prevail and tasks must be prioritized. However, scholars lack a theoretical model of how accountability relations affect implementation behaviors that are inconsistent with policy. By extending the Accountability Regimes Framework (ARF), this paper explains how multiple competing subjective street-level accountabilities translate into policy divergence. The anti-terrorism “Prevent Duty” policy in the United Kingdom requires university lecturers to report any student they suspect may be undergoing a process of radicalization. We ask: what perceived street-level accountabilities and dilemmas does this politically contested policy imply for lecturers, and how do they affect divergence? An online survey of British lecturers (N = 809), combined with 35 qualitative follow-up interviews, reveals that accountability dilemmas trigger policy divergence. The ARF models how street-level bureaucrats become informal policymakers in the political system when rules clash with their roles as professionals, citizen-agents, or “political animals.”  相似文献

“Future generations” play a key role in current political debates. In the context of the climate crisis especially, political controversies are often framed as moral problems of “intergenerational justice.” This article aims to historicize the use of the concept of “future generations” in modern political discourse and to uncover its long—and often ambivalent—history. Its main argument is that talking about “future generations” was part of an attempt to integrate (distant) futures into the political discourse of the time. The first part of the article outlines a theoretical perspective on the relationship between generations and temporalities. The second part focuses on how anticipating “future generations” became an important part of the history of utopian thinking and political planning in the nineteenth and early twentieth centuries, especially in the realm of demographic and economic discussions. The third part analyzes the emergence of “future ethics” and “intergenerational justice” as important political discourses in the 1970s. This part refers both to the academic debates about “future generations” and to the way political decision-makers used the concept to legitimize their policies. The article argues that the concept of “future generations” should not be taken as an ethical principle that transcended the political debates of the present. Rather, it was itself the result of intense political controversies.  相似文献

Cultures of Experiment. – It is generally accepted that the development of modern science is rooted in experiment. Yet for a long time, experimentation did not occupy a prominent role in history of science. With the practical turn in science studies, this has begun to change. This paper is concerned with cultures of experiment. In the first part, a suggestion is made as to how the concept of experimental culture can be used to go beyond a history of disciplines. In the second part, a particular experimental culture in the life sciences is looked at more closely. A survey is given on the changing forms of in vitro experimentation, that is, on analyzing biological functions in a test tube.  相似文献

This article highlights the role of food as an essential tool for immigrant Mapuche families to reinforce their ethnic identity and pass it on to the younger generations in Santiago de Chile. Food and food-related practices were a topic that many Mapuche referred to when they were invited to talk about their culture and life in Santiago; this simultaneously revealed their relation to ‘others’ (Chileans) and their connectedness to their ancestral lands in the Araucania region in the south. Staying attuned and connected to the south through Mapuche food strengthens feelings of cultural continuity and belonging, such that Mapuche ethnic identity does not surrender to the city, but rather is re-created in a new environment.  相似文献

The period from 1870 to 1914 plays a unique role in the history of natural resource exploration and extraction. This article analyses, from a Swedish viewpoint, the connections between two actor categories of special importance in this context: scientific-geographical explorers and industrial actors. The article examines their activities in three broadly defined regions: the Arctic, Russia, and Africa. We show that the Swedes generally had far-reaching ambitions, on par with those of the large imperial powers. In some cases, notably in Africa, Sweden was not able to compete with the larger imperial powers; but in other cases, such as the exploration of the Arctic – from Spitsbergen to Siberia – and the industrial exploitation of coal at Spitsbergen and petroleum in Russia’s colonial periphery, Swedish actors played a leading role, in competition with players from the larger European nations. Our paper shows that scientific exploration and industry were closely linked, and that foreign policy also influenced the shaping of these links. We distinguish different types of knowledge produced by the Swedish actors, pointing to local, situated knowledge as the most important type for many resource-based businesses, although modern, scientific knowledge was on the increase during this period.  相似文献

This paper discusses the underlying causes behind the masculinization of poverty during the period of 1957–1981 in Sweden. Testable hypotheses are derived from a theoretical framework. The findings suggest that the male role as breadwinner disappeared during the analysed period. Lowly educated men and especially male immigrant labour lost their labour market position when industrial society gave way to a new post-industrial society, with an expanding service sector bringing numerous new employment opportunities for women. When sick or unemployed, social assistance was the only social security these men had available. On the other hand, the welfare-state expansion targeted women, particularly single mothers and widows, and thus reduced the number of native women claiming social assistance. The findings also point to the process character of the masculinization of poverty, arguing that women gained significantly more than men from the expansion of the welfare state.  相似文献

Restructuring of global and local markets has led to an increased influence of commodity derivatives markets on commodity price setting. This has critical implications for price risks experienced by actors along commodity chains. Commodity derivatives markets have undergone significant changes that have been referred to as the ‘financialization of commodities’, which we define as an increase in trading activity by financial investors and the reorientation of business strategies by commodity trading houses towards risk management and financial activities. This article assesses how these global financialization processes affect commodity producers in low‐income countries via the operational dynamics of global commodity chains and national market structures. It investigates how prices are set and transmitted and how risks are distributed and managed in the cotton sectors in Burkina Faso, Mozambique and Tanzania. It concludes that uneven exposure to price instability and access to price risk management have important distributional implications. Whilst international traders have the capacity to deal with price risks through hedging, in addition to expanding their profit possibilities through financial activities on derivatives markets, local actors in producing countries face the challenge of increased short‐termism — albeit to different extents depending on national market structures — with limited access to risk management.  相似文献
