Abstract

We use the Location Affordability Index (LAI) and the newly developed Child Opportunity Index (COI) to assess, for the first time, the tradeoff between neighborhood opportunity and housing/transportation affordability facing low-income renter families in the 100 largest metropolitan areas. In addition to describing the opportunity/affordability relationship, we explore the level of balance between neighborhoods’ relative cost burden and their corresponding opportunity levels to determine whether children of different racial/ethnic groups are more (or less) likely to experience cost-opportunity imbalance. Our multilevel analyses show that housing affordability is largely accounted for by the neighborhood opportunity structure within each metropolitan area. The metropolitan characteristics examined account for only a small proportion of the between-metro variance in the opportunity/affordability gradient for housing, presumably because the neighborhood opportunity structure already reflects metro area factors such as fragmentation and segregation. On the other hand, transportation affordability shows a weaker association with neighborhood opportunity. The COI/LAI association is much weaker for transportation than for housing, and a large part of the variation in the transportation gradient occurs at the metropolitan area level, not the neighborhood level. Sprawl is particularly associated with transportation affordability, with lower sprawl areas having lower transportation-cost burden. We discuss the implications of the empirical findings for defining affordability in housing assistance programs. We recommend that housing policy for low-income renter families adopt an expanded notion of affordability (housing, transportation, and opportunity) and explicitly consider equity (e.g. cost-opportunity imbalance) in the implementation of this expanded affordability definition.  相似文献

This article provides an analysis of the nature of circuit court threshold decisions. Specifically, a model sensitive to the institutional context of the circuits is developed and tested across all threshold decisions in the sample and in more limited samples of proper party and proper forum votes. The results suggest that circuit court gatekeeping is a function of multiple factors, including circuit court law, litigant status, the lower court decision, and, at times, the ideological preferences of the circuit judge or that of his or her circuit.  相似文献

The dismantling of the welfare state across the United Kingdom (and indeed a number of other Western industrialised democracies, such as Canada and the United States) and the reductions to welfare provisions and entitlements are having a detrimental impact on women’s equality and safety. Towers and Walby argue that the recent cuts to welfare provision in the United Kingdom, particularly for women’s services, could lead to increased levels of violence for women and girls. This paper makes the argument that female victims of domestic abuse experience violence on two levels: first, at the intimate/personal level through their relationship with an abuser and, second, at a structural level, through the state failing to provide adequate protection and provision for women who have experienced violence in intimate relationships. Using a specific example of post-violence community services delivered to both the children of women who have experienced domestic violence and the women themselves, this paper draws on empirical research carried out in 2010–2011 with London-based third-sector and public sector organisations delivering the Against Violence and Abuse Project ‘Community Group Programme’. We argue that the lack of services for women involved in, or exiting, a violent relationship can amount to state-sanctioned violence, if funding is withheld, or indeed, stretched to breaking point.  相似文献

How do civilians respond to civil war narratives? Do they react to ethnic frames more strongly than to alternatives? Governments and rebels battle for hearts and minds as well as strategic terrain, and winning the narrative war can shift legitimacy, popular support, and material resources to the sympathetically framed side. We examine the effect of one‐sided and competing war discourses on ordinary people's understandings of the Syrian civil war—a conflict with multiple narratives, but which has become more communal over time. We conduct a framing experiment with a representative sample of Syrian refugees in Lebanon in which we vary the narrative that describes the reasons for the conflict. We find that sectarian explanations, framed in isolation, strongly increase the importance government supporters place on fighting. When counterframed against competing narratives, however, the rallying effect of sectarianism drops and vanishes.  相似文献

At a time when Europe faces numerous crises, there is a real need for rigorous evidence to underpin effective policymaking. However, a gap between academia and policy creates clear obstacles in the use of evidence in policymaking. Many of these enduring obstacles are manifest in the inherent differences between separate communities: academics have difficulty communicating research in an applicable manner, and policymakers, in turn, tend to focus on operational motivations. The gap widens considerably when foreign, security and defence policy within the complex institutional structures of the European Union is considered. In addition to these well known barriers to evidence-based policy, there are two more obstacles in the defence and security space: sovereignty and dispersed decision-making. A dialogue of best practices must be opened up to broker knowledge in the EU context.  相似文献

We discuss an experiment employing participatory technology assessment (pTA), a public deliberation method for eliciting lay citizen input prior to making decisions about science and technology to inform upstream engineering decisions concerning technical aspects of NASA’s Asteroid Initiative. In partnership with NASA, the Expert and Citizen Assessment of Science and Technology network conducted a pTA forum on NASA’s Asteroid Initiative in 2014. The goal of the exercise was to assess citizens’ values and preferences about potential asteroid detection, asteroid mitigation, and exploration-based technologies associated with NASA’s Initiative. This article discusses the portion of the forum that focused on the Asteroid Redirect Mission, an effort to redirect an asteroid into lunar orbit that astronauts can study. The forum sought public input on two options for performing the mission that NASA included in technical assessments to make a down select decision: Option A to capture a 10-meter-diameter asteroid; or Option B to redirect a several-meters-diameter boulder from the surface of a larger asteroid. We describe the values and perceptions participants had about Option A and B, how these results were used by NASA managers, and the impact the results of the pTA had on the down select.  相似文献

This paper explores the possibilities of combining DOD technology transfer mechanisms to systems architecture techniques as a means to shorten program acquisition timelines while still providing high technology, robust tools to the women and men serving in the United States military. A literature search demonstrates that few articles have been published on the relationship between systems architecture and technology transfer. However, any DOD laboratory that employs more than 200 scientists and engineers is required by law to have a full time Office of technology transfer, so why has so little research been performed on the synergies between the two DOD disciplines? This paper will describe the ways that the systems architecture tools and practices, and technology transfer transactional mechanisms available to all DOD laboratories, can be utilized to increase knowledge sharing with small business and industry partners to shorten acquisition cycles.
