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

Using data gathered from a sample of two hundred jail inmates housed in a large California city, this research extends the still nascent literature on the self-control/gang membership association. The article begins by first articulating more comprehensively than earlier research Gottfredson and Hirschi's theoretical justification for expecting a self-control/gang membership link. Next, an examination is undertaken of the relative independent influences on gang membership of self-control and a series of measures, derived from differential association theory, that mainly tap familial gang involvement. On the whole, logistic regression models suggested that self-control exerted an effect on gang membership that was almost entirely independent of, but also modest in comparison to, familial gang involvement effects, although the results also indicated the insignificance of self-control upon controlling for a series of differential association measures. Finally, theoretical implications of the findings and suggestions for future research are offered.  相似文献

This article examines the prediction of recidivism using the Global Risk Assessment Device (GRAD), a reliable and valid measure of dynamic factors associated with family characteristics, peers, mental health, substance abuse, trauma exposure, educational concerns, accountability, and health risks. Using a sample of adult caregivers of first-time misdemeanant offenders, two factors-education and accountability-were significantly associated with recidivistic behavior, supporting the use of GRAD data in correctly identifying first-time offenders who have the greatest and the least likelihood for future offending behavior. Additional analyses utilizing parent reports on African American males indicate that the GRAD provides discrimination in the prediction of recidivism in a group typically seen as being high risk simply because of their gender and race. The assessment drives intervention approach of the GRAD is discussed in terms of using reports from adults to accurately place youth into appropriate levels of supervision and treatment.  相似文献

Since the 1980s, the USA has fought cocaine in the Andes with carrots and sticks: interdiction and crop eradication wield the sticks, while Alternative Development (AD), which offers economic assistance to farmers who voluntarily abandon illicit cultivation, provides the carrots. Yet cocaine continues to permeate US streets, and rural Andean communities remain isolated from the legitimate economy. Many critics blame US belligerence for compounding the Andean drug war. The underlying problem with the existing strategy, however, might not be the aggressiveness of its military sticks, but the flimsiness of its development carrots. The inability of AD to persuade farmers to abandon coca cultivation may be causing US policy makers to over-apply military solutions – often inflaming rural communities and exacerbating regional instability in so doing. Few legal crops can match the earning power of coca. The article therefore suggests that the US carrot could be made more attractive by adopting a Venture Development model which helps rural farmers to process their legal produce into high-quality finished goods that command premium prices. Such a strategy could conceivably choke the cocaine engine by applying market-based forces to address market-based realities.  相似文献
