We develop front‐door difference‐in‐differences estimators as an extension of front‐door estimators. Under one‐sided noncompliance, an exclusion restriction, and assumptions analogous to parallel trends assumptions, this extension allows identification when the front‐door criterion does not hold. Even if the assumptions are relaxed, we show that the front‐door and front‐door difference‐in‐differences estimators may be combined to form bounds. Finally, we show that under one‐sided noncompliance, these techniques do not require the use of control units. We illustrate these points with an application to a job training study and with an application to Florida's early in‐person voting program. For the job training study, we show that these techniques can recover an experimental benchmark. For the Florida program, we find some evidence that early in‐person voting had small positive effects on turnout in 2008. This provides a counterpoint to recent claims that early voting had a negative effect on turnout in 2008. 相似文献

Cultural Penetration and Punctuated Policy Change: Explaining the Evolution of U.S. Energy Policy 下载免费PDF全文
Punctuated equilibrium theory (PET) suggests that the policy process is characterized by long periods of incremental change and short periods of punctuated change. The impetus for the latter is usually a focusing event that breaks open policy monopolies, allowing for major changes in legislative decision making. While a burgeoning body of literature, a shortcoming in the PET literature is that it has yet to explain why focusing events and subsequent breakdowns in policy monopolies sometimes fail to result in punctuated policy. We integrate theories on cultural change with punctuated equilibrium to explain why focusing events do not always result in the dramatic policy changes that we might expect. Specifically, we use the context of national energy policy and the lexical database, Google Ngram Viewer, to trace punctuating energy‐related events and the occurrence or lack thereof subsequent policy change from 1952 to 2000. 相似文献

Quantitative literature discussing violence in civil conflicts tends towards a typical model of engagement between governments and revolutionaries. Whilst recent work has shown the significant impact of multiple anti-government groups, a further feature remains understudied—the role of pro-state militants. This article theorizes a “violence premium” when such groups arise, which leads to all connected groups devoting greater energy to conflict than they would in isolation. Employing duration analysis and data from The Troubles in Northern Ireland, where Republicans act as revolutionary insurgents, Loyalists as pro-state militants, and the British Army as government forces, the violence premium is empirically confirmed. Both Loyalists and Republicans deviate from their underlying strategies to attack more frequently when violence by their rivals increases, with Republicans and the British Army engaging in the same way. An extended analysis, accounting for the status of the victim, shows that the violence premium resulting from interaction between Loyalists and Republicans targeted only the civilian population of Northern Ireland, elucidating the sectarian component of The Troubles. These results show that including all conflict parties and considering how they are linked are important features in studies that aim to determine the net level of violence in civil conflicts. 相似文献

ABSTRACTIn responding to the 2016 reformulation of the United Nation’s Sustainable Development Goals, the development community’s efforts are focused on a sweep of initiatives aiming to promote whole-society, sustainable development. The ambition of the SDGs is inspiring, but also daunting, and does not always sit easily within national models of economic development. This viewpoint profiles two organisations in the south Indian state of Tamil Nadu, that have decades of experience in whole-person development among scheduled tribes and disability communities. Both organisations serve as timely examples of ongoing holistic, whole-person health and development in the context of new ideals and economic realities. 相似文献

Trade has again emerged as a controversial issue in America, yet we know little about the ideas that guide American thinking on these questions. By combining traditional survey methods with experimental manipulation of problem content, this study explores the ideational landscape among elite Americans and pays particular attention to how elite Americans combine their ideas about commerce with their ideas about national security and social justice. We find that most American leaders think like intuitive neoclassical economists and that only a minority think along intuitive neorealist or Rawlsian lines. Among the mass public, in contrast, a majority make judgments like intuitive neorealists and intuitive Rawlsians. Although elite respondents see international institutions as promising vehicles in principle, in practice they favor exploiting America's advantage in bilateral bargaining power over granting authority to the World Trade Organization. The distribution of these ideas in America is not arrayed neatly along traditional ideological divisions. To understand the ideational landscape, it is necessary to identify how distinctive mentaal models—mercantilist, neorealist, egalitarian, and neoclassical economic—sensitize or desensitize people to particular aspects of geopolitical problems, an approach we call cognitive interactionism. 相似文献

This article proposes agendas for teaching and research about shifting global patterns of equality and inequality, a very different agenda than was appropriate when the last undergraduate professor was president of ISA, almost forty years ago. Today, unlike in that Cold War world, formal democracy is flourishing, state power is diminishing, gender inequality has diminished, and income inequality has risen. Consequences of these new patterns that demand our attention as teachers and scholars include: (1) more frequent protracted social conflicts, (2) a newly politicized sphere of international public health, (3) the new global gender politics, (4) the new global politics of the super-rich, and (5) the new politics and ethics of the world's privileged, a group that includes most ISA members and most of our students. Our responsibilities as teachers have grown, in part, because popular media present a decreasingly coherent picture of each of these patterns; and that incoherence, itself, may help sustain global inequalities. 相似文献

The disintegration of the Soviet Union had profound economic and social effects on many of the newly independent transition economies. Nowhere was this more so than in the fisheries sector – with one of the biggest production shortfalls occurring in Kyrgyzstan, following the collapse of lake capture and pond-culture production. In 2005, aggregate landings were just 48 tonnes – barely 3 per cent of the catch level recorded in 1989. This article has two objectives. First it analyses the extent to which the dissolution of the Soviet Union can explain the collapse of the fisheries sector in Kyrgyzstan. Second, in the light of these findings, it considers what practical steps, if any, might be taken to revitalize the sector. 相似文献

Certified aircraft mechanics represent the largest gender-based demographic disparity in aviation with a 49-to-1 male-to-female ratio. Recent research into women’s perspective on the aircraft mechanic career field revealed that a large majority of women felt unsure or negatively about their potential promotion opportunities and social acceptance. The purpose of this follow-on mixed-methods concurrent triangulation study was to explore the perspectives of men regarding the aforementioned topics to see if they differ from previously published research on women perceptions. A total of 587 men and 431 women completed an eight-question survey containing 5-point Likert-type and open-ended questions. The quantitative comparison consisted of the total 1018 responses, while only the survey responses from the 587 men were analysed for correlations and qualitative codes. Results indicated that there was a significant difference between the perceptions of men from those of the women regarding work environment safety and social acceptance. Additional correlation analysis revealed social acceptance to be a key variable when predicting career appropriateness, advancement opportunity and work environment safety. The 587 qualitative responses yielded results that differed from those of women, citing an assumption that women have the same advancement opportunities or be as socially accepted as men entering the field. 相似文献

Psychological empowerment encompasses several key aspects of youth civic and sociopolitical development. Most research has focused on psychological empowerment’s emotional component, which entails learned hopefulness about one’s own ability to participate in and lead community change efforts. Fewer studies have assessed critical awareness of how social power operates—psychological empowerment’s cognitive component. The confluence of these two components has been termed critical hopefulness. A complex relationship exists between these two components, and previous research has found relatively small proportions of participants reporting both high levels of critical awareness and simultaneously high levels of hopefulness about their ability to exert influence in the sociopolitical domain. The current study of urban high school students in the Northeastern U.S. (n?=?389; 53.5% female) investigates heterogeneity according to these two components of psychological empowerment. Latent class cluster analyses were conducted and seven distinct groups of participants emerged. Students identifying as Hispanic/Latinx were more likely to be classified into a profile group exhibiting critical hopefulness. Differences were observed between psychological empowerment profile groups on self-reported levels of psychological sense of community, civic engagement, and social justice orientation. Furthermore, a larger proportion of this overall sample was classified into groups that exhibited critical hopefulness than in a previous study of adults. These findings provide useful insights for efforts to engage young people in civic life and to promote sociopolitical development. 相似文献

This paper explores the political field that has opened up in the wake of the recent civil war in Nepal. We focus on cultural-political developments in agrarian districts, where some of the most intriguing openings, and indeed the most pernicious closures, can be witnessed (as opposed to the national-state restructuring that commands more media and popular attention). Our research asks what spaces open up in the emerging political field at the district scale to entrench or transform dominant cultural codes and sedimented histories of socio-economic inequality. Preliminary research identifies specific sectors of local governance that have emerged as significant sites of struggle over the shape and meaning of ‘democracy’, namely forest management and infrastructure development. The primary contribution of the paper lies in specifying an analytical approach to the study of ‘post-conflict’ governance at the local scale via three conceptual terrains of inquiry – governance and planning, political subjectivity, and cultural politics. The ultimate objective is to develop a framework for assessing the conditions of possibility for a democratic restructuring of economy and society to accompany the official political institutions of liberal democracy. 相似文献
