Addressing climate change requires consideration of mitigation and adaptation opportunities at multiple spatial scales. This is particularly true in the built environment, defined here to include individual buildings, neighborhoods, and the spaces between. The current U.S. political environment portends fewer resources and coordinating services for mitigation and adaptation at the federal level, however, reinforcing the relevance and necessity of actions at subnational levels. In this study, we evaluate the applicability of a polycentric model of governance to the implementation of mitigation and adaptation practices, as well as the presence of polycentric systems in the built environment. We assemble a database of practices with the potential to achieve both mitigation and adaptation objectives, as well as those that may be cross‐purposed or that may achieve one but not the other. We review practices to gauge the applicability of a polycentric model of governance to mitigation and adaptation practices in the built environment, and examine the attributes of three existing adaptation and/or mitigation programs to assess the extent to which they exhibit polycentric attributes. We conclude with recommendations for a broader research agenda, including efforts to develop more in‐depth examinations into individual programs and comparative analysis of performances of different governance attributes. 相似文献
To evaluate the effect of emergency winter homeless shelters on property crimes in the nearby communities.
Methods
Every winter between 2009 and 2016, the City of Vancouver, Canada opened shelters to protect the homeless from harsh winter conditions. The city opened 19 shelters, but only five to nine of them were open in any one winter. Using the variation in timing and placement of the shelters, we contrast crime rates in the surrounding areas when the shelters are open and closed.
Results
The presence of a shelter appears to cause property crime to increase by 56% within 100 m of that shelter, with thefts from vehicles, other thefts, and vandalism driving the increase. However, when a homeless shelter opened, rates of breaking and entering commercial establishments were 34% lower within 100 m of that shelter. The observed effects are concentrated close to shelters, within 400 m, and dissipate beyond 400 m. Consistent with a causal effect, we find a decreasing effect of shelters with increasing distance from the shelter.
Conclusions
While homeless shelters are a critical social service, in Vancouver, they appear to impact property crime in the surrounding community. Shelters may warrant greater security to control property crime, but the data suggest that any increase in security need not extend beyond 400 m, about two to three blocks, from the shelters.

There is a belief in the criminal justice system that it is better to take a plea offer to avoid uncertain consequences than risk going to trial. Prior studies using the data in Anglo-American courts have suggested that many legal and extralegal factors influence the decision of a guilty plea versus trial. China developed its own plea-bargaining system in 2016. Using 6826 DUI cases adjudicated in six cities, this study examines what factors affect the decision of a guilty plea and whether the guilty plea brings true benefits in Chinese courts. The results show that more serious crimes and more dangerous defendants were less likely to be disposed of through guilty pleas (as opposed to going to trial). One possible explanation is that prosecutors may make more punitive offers in these cases, which in turn discourages defendants from accepting them. In addition, using a propensity score weighting technique to control for potential confounding variables, this study finds that defendants who pleaded guilty were more likely to receive favorable case outcomes regarding pretrial detention and probation decision, which supports the argument that a guilty plea could help a defendant to avoid the “trial penalty” in Chinese criminal justice system.
