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

The eyes of fourteen fatally abused children and sixteen control cases were examined histopathologically. Ten of the abused children showed intraocular change. The most common ocular changes were subdural hemorrhage of the optic nerve and retinal hemorrhage which involved all the layers of the retina, but most commonly the nerve fiber layer, ganglion cell layer and inner nuclear layer. The presence of blood cavities within the retina partially supported the hypothesis of traumatic retinoschisis. The control cases of non-abused children rarely showed intraocular hemorrhage. 相似文献

Lorraine Benson's body was found beaten and strangled at Raynes Park, Surrey, in December 1988. Considering the possibility of linked offences, a murder squad was set up to work alongside a team already investigating a rape series in the Kingston area. A man's handkerchief left at a site a quarter of a mile from the murder scene was found to be stained with blood and saliva matching that of the victim. A DNA profile was obtained from a stain of nasal mucus on this handkerchief and found to match a suspect later arrested for an attempted rape in the same locality. Also of forensic interest were dust marks made by the zips of the victim's and defendant's coats and identification of the rope used for strangulation. 相似文献

Policymakers have actively pursued urban renewal and dispersal programs to deconcentrate poverty in urban neighborhoods. Relocation strategies lead to new housing opportunities and may encourage employment opportunities for relocated residents if resourceful contacts and job information become more easily available after the move. This study provides an innovative evaluation of the early impacts of involuntary relocation programs in the Netherlands on the housing careers, earnings and employment rates of forced relocatees. It establishes a quasi-experimental design by employing unique longitudinal individual-level population registry data from Statistics Netherlands: forced relocatees are tracked and matched to a control group consisting of similar residents that were not forced to move. A difference-in-difference design shows that forced relocatees are living in less deprived neighborhoods after the move. However, we find no conclusive evidence that this upgrade in housing leads to more socioeconomic opportunities for the forced relocatees. 相似文献

There is widespread evidence that individuals select information that supports their convictions and worldviews. This behavior yields the formation of echo chambers – environments in which an individual’s own political beliefs are repeated and amplified and dissenting opinions are screened out. Recent research demonstrates that social networking sites such as Facebook or Twitter can facilitate this selection into homogenous networks. Using data from a representative nation-wide online survey, we consider the degree to which respondents’ social media networks resemble virtual echo chambers. We then analyze the effect of these social media echo chambers on satisfaction with democracy among Democrats and Republicans in the aftermath of the 2016 US elections. Our findings reveal that virtual echo chambers boost democratic satisfaction among Republicans but they do not have an effect on system support by self-identified Democrats. Our paper therefore adds to a growing literature linking online behaviors to mass attitudes about politics. 相似文献

Participatory governance offers the potential to deliver responsive and accountable services. This article tests this expectation by looking at how members of participatory extension platforms in Malawi understand the meaning of “demand-driven” services, and allocate responsibility and influence in service provision. Results show that most respondents agree on bottom-up extension services that respond to expressed farmers’ needs (86% of respondents), and assign responsibility and influence widely across state and non-state actors. While these findings suggest that these participatory mechanisms can promote responsiveness to farmers’ needs and accountability, they also point toward different governance challenges in extension services. 相似文献

What role have the processes and institutions of international development played in creating and propagating ideas around the world? This paper demonstrates that networks of development-focused civil society institutions can form global epistemic bridges even where communication technology, global markets, infrastructure, or state services do not reach. Given the penetration of these ‘civil society knowledge networks’ throughout the world, it is crucial to understand how these networks form, and how they create and spread ideas, mediating between global discourses and local needs. This paper builds on a multi-sited case study of one such civil society knowledge network, which includes an international foundation, its partner non-governmental organisations (NGOs) in Kenya, and one village where these NGOs run a forest conservation project. The case study provides a closely textured analysis of the mechanisms of knowledge production and consumption in the network, including personality politics, language, technology, political connections and the power dynamics of knowledge flows. It demonstrates the ways remoteness and disconnection are overcome through the epistemic reach of institutional networks involved in development interventions. 相似文献
