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

The photograph of Ai Weiwei’s middle finger set against the backdrop of Tiananmen Square has become an icon of politically subversive art. But can we see beyond the middle finger? Here I argue that current theories of political aesthetics (e.g. Jacques Rancière) operate on an oversimplified dichotomy between two competing paradigms of political art, and that this threatens a more nuanced engagement with contemporary artistic practices. In the first part, I re-examine both the antagonistic relation between art and politics exemplified in Plato's verdict against poetry as a socially corrosive form of imitation as well as the instrumental relation of art and politics developed in Friedrich Schiller’s conception of aesthetic education as a means of social and political reform. Then, drawing on recent work by the controversial Chinese artist, I argue for a model of political art that can account for the more complex interrelation of criticism and cultural affirmation evident in a growing body of politically-oriented art.  相似文献

In recent years a bewildering array of smartphone applications (“apps”) has emerged to support separated parents' communication. Post-separation parenting apps vary in cost and features; they typically comprise a messaging tool, shared calendar, expense tracker and a means to export records for legal purposes. A key challenge for separated parents and family law practitioners alike is knowing which apps or app feature(s) can work well for different family contexts, needs and budgets. The present study sought to evaluate nine popular post-separation parenting apps and their features using small-n Human–Computer Interaction methods. Mediators role-played high conflict ex-couples while completing a set of five common post-separation communication or organizational tasks. A cross-case analysis of ratings was conducted. We found that (a) many of the mediators changed their apparent enthusiasm for co-parenting apps once they had used the apps themselves; (b) all nine apps were rated somewhere between “Poor” to Fair’; and (c) features of some of the best-known apps were not rated as highly as some of the features of more recent, lesser-known apps.  相似文献

Correctional officers work in a highly challenging environment and are at a heightened risk of a range of negative stress-related health conditions. This study examines how correctional officer responses to adversity moderate the association between perceived workplace adversity and psychological well-being. The aim was to assess the degree that perceived workplace adversity predicts correctional officer psychological well-being and the subsequent impact on negative organizational outcomes such as absenteeism, presenteeism and job dissatisfaction. Hundred and seventy four officers completed an online questionnaire including measures of perceived workplace adversity, officer responses, psychological well-being and organizational impact. Structural Equation Modelling revealed that a heightened perception of workplace adversity predicted lower psychological well-being and in turn increased negative organizational impacts. Analyses indicated that using an interpersonal/solution focused response style moderated the relationship between perceived workplace adversity and psychological well-being, reducing its negative impact on well-being and in turn the frequency of negative organizational impacts. These findings offer insight into how officers’ perceptions of their working environment and how they respond to workplace adversity influence their psychological well-being and the organizations that employ them.  相似文献

As technology has become an ever-present facet in the lives of young people, they have become reliant on it to form and maintain relationships. It has also helped facilitate negative relationship behaviors, such as the monitoring of romantic partners without their permission (aka cyberstalking). The purpose of this study is to investigate theoretical predictors of cyberstalking in a sample of university students by applying General Theory of Crime and Social Learning Theory. Results indicated that low selfcontrol and deviant peer association are significant predictors of cyberstalking, specifically attempting to log-in to a person’s social media, as well as social media presence and sex.  相似文献

Objectives

This research examines the effect global positioning system (GPS) technology supervision has on pretrial misconduct for defendants facing intimate partner violence charges.

Methods

Drawing on data from one pretrial services division, a retrospective quasi-experimental design was constructed to examine failure to appear to court, failure to appear to meetings with pretrial services, and rearrest outcomes between defendants ordered to pretrial GPS supervision and a comparison group of defendants ordered to pretrial supervision without the use of monitoring technology. Cox regression models were used to assess differences between quasi-experimental conditions. To enhance internal validity and mitigate model dependence, we utilized and compared results across four counterfactual comparison groups (propensity score matching, Mahalanobis distance matching, inverse probability of treatment weighting, and marginal mean weighting through stratification).

Results

Pretrial GPS supervision was no more or less effective than traditional, non-technology based pretrial supervision in reducing the risk of failure to appear to court or the risk of rearrest. GPS supervision did reduce the risk of failing to appear to meetings with pretrial services staff.

Conclusions

The results suggest that GPS supervision may hold untapped case management benefits for pretrial probation officers, a pragmatic focus that may be overshadowed by efforts to mitigate the risk of pretrial misconduct. Further, the results contribute to ongoing discussions on bail reform, pretrial practice, and the movement to reduce local jail populations. Although the cost savings are not entirely clear, relatively higher risk defendants can be managed in the community and produce outcomes that are comparable to other defendants. The results also call into question the ability of matching procedures to construct appropriate counterfactuals in an era where risk assessment informs criminal justice decision-making. Weighting techniques outperformed matching strategies.

A review of the literature concerning the fate and behavior of gunshot residue (GSR) is presented. A number of concomitant parameters including firearm and ammunition type, plume and GSR material characteristics, travel distances, chemical composition and GSR morphology are critically discussed in relation to their effects on the distribution and deposition, transfer and persistence processes of GSR. The underlying mechanisms associated with such processes are also considered. Knowledge of these processes on GSR materials could provide valuable information concerning scene preservation and subsequent forensic sampling. The number of GSR particles deposited can vary significantly with each firearm discharge, highlighting the potential to produce distinctive data in each individual case. With the continual development and compositional changes of new ammunition types, further evaluation of the effect these processes may have on GSR evidence and their possible influence on the interpretation of the analytical results should be given due consideration.  相似文献

While the punishment of juvenile offenders has increasingly become an issue of major concern to the public, there are few studies that test the government's coercive response to offending by this particular group. This study addresses this issue by examining the variation in sentence length for juvenile offenders adjudicated in the adult criminal courts for violent offenses. Results from the regression analyses consistently show that, while factors related to the specific offense are important contributors to the variation in sentence length, differences in the ideological climate of each state are a strong predictor of the variation in adult sanctions for minors. Specifically, the findings show that conservative citizen ideology and Republican control of state government are important contributors to the variation in sentencing of juveniles across U.S. states. Additional evidence shows that states where judges must run in an election to gain their seats proscribe more severe sanctions on juvenile offenders by sentencing more of them to adult prisons. Overall, the results suggest that the social and political climate of each state plays a very strong role in the sentencing of juvenile offenders to adult prisons.  相似文献

Which individuals are most responsive to get-out-the-vote (GOTV) messages that emphasize the social aspects of voting? Recent literature has shown that GOTV messages that emphasize the social environment in which an individual is embedded are particularly effective at increasing voting rates. Until now, we have not had good estimates for the types of people for whom social GOTV messages are most effective. We report a new set of disaggregated results of a randomized controlled trial of political mobilization messages delivered to 61 million Facebook users during the 2010 U.S. Congressional elections. The results suggest that social endorsement cues are differentially effective for different types of political behaviors—political expression, information seeking, and voting—and for different kinds of people, based on both demographic and social characteristics, raising new questions about the mechanisms explaining social pressure effects.  相似文献

The verdict delivered by voters in the 2015 and 2017 British General Elections and the European Union Referendum surprised pollsters, pundits, the media, and even the victors. Political choices representative of Globalist outlooks saw defeat at the polls. Liberal Democratic support was below 10% and voting to remain in the EU underperformed predictions. Empirical analyses demonstrate that there is a Nationalist–Globalist policy divide, partially rooted in demographics and authoritarian predispositions, which go beyond traditional valence factors in explaining the recent choices of the British electorate. Moreover, this outlook influences how satisfied citizens are with the way democracy works in Britain. Nationalist viewpoints, when juxtaposed against Globalist outlooks, are salient in a way they were not during the height of Thatcherism, encompass left–right economic concerns and may portend a new era in British political culture.  相似文献
