Race, Class or Neighborhood Context: Which Matters More in Measuring Satisfaction with Police?

The primary purpose of this study is to assess the relative effects of race and class, at both individual and neighborhood levels, on public satisfaction with police. Using hierarchical linear modeling on 1,963 individuals nested within 66 neighborhoods, this study analyzes how individual-level variables, including race, class, age, gender, victimization and contact with police, and neighborhood-level factors, including racial composition, concentrated disadvantage, residential mobility and violent crime rate, influence residents\u27 satisfaction with police. The results from the individual-level analysis indicate that both race and class are equally important predictors. African Americans and lower-class people tend to be less satisfied with police. The significant effects of race and class, however, disappear when neighborhood-level characteristics are considered simultaneously. Neighborhood racial composition affects satisfaction with police, with residents in predominately White and racially mixed neighborhoods having more favorable attitudes than those in predominately African American communities. Further analyses reveal that African Americans in economically advantaged neighborhoods are less likely than Whites in the same kind of neighborhoods to be satisfied with police, whereas African Americans and Whites in disadvantaged communities hold similar levels of satisfaction with police. Implications for future research and policy are discussed

Neighborhood Characteristics and Crime: A Test of Sampson and Groves\u27 Model of Social Disorganization

In 1989 Sampson and Groves proposed a model of social disorganization. In this model, neighborhoods with low socioeconomic status, high residential mobility, racial heterogeneity, and family disruption were predicted to have sparse local friendship networks\u27, low organizational participation, and unsupervised youth groups. These, in turn, were predicted to increase neighborhood crime rates. Although Sampson and Groves\u27 work represents the most complete model of social disorganization to date, it has only been tested twice and then on the same data set. Using data from 36 neighborhoods from 7 U.S. cities, this study examines extensions of Sampson and Groves\u27 model suggested by past research findings. The results indicate that Sampson and Groves\u27 model is modestly supported by the data. Social disorganization variables are more effective in transmitting the effects of neighborhood structural characteristics on assault than on robbery. Implications of the study and directions for future research are discussed

Social Disorganization and the Ability and Willingness to Enact Control: A Preliminary Test

Dominant models in the social disorganization literature differentially focus on the ability of neighborhoods to enact social control and the willingness to do so. Despite the interest in both concepts, often no clear definition of either is provided, and there is little discussion of their relationship or how they interact to affect neighborhood crime rates. This paper begins to explore the relationship between ability and willingness to enact social control. The findings suggest that, for formal control, ability and willingness are closely related. Furthermore, at the aggregate level, concentrated disadvantage combined with perceived inability has a strong impact on neighborhood crime rates

Justifications for the Probation Sanction Among Residents of Virginia--Cool or Un-Cool?

Perhaps as evidence of a growing cultural gap between our students and ourselves, one of the authors was recently amused when a student asked whether probation was a cool sanction. In this study, we begin an investigation into how cool the probation sanction is in the eyes of residents of the Commonwealth of Virginia. Specifically, we use data from a telephone survey of 840 registered voters to explore three questions. First, how often would they recommend the probation sanction in comparison to other sanctions? Second, how do they justify the sanction relative to justifications for other sanctions? Finally, are their justifications and sentencing recommendations consistent across crimes? We address these questions in this study to see whether the sanction is cool or uncool. In the review of literature, we discuss punishment justifications in general and probation as a punitive experience

Institutional strength, social control and neighborhood crime rates. Th eoretical criminology

Abstract While the systemic model that today's theories of social disorganization are based on acknowledges that neighborhoodbased institutions may vary in their ability to contribute to effective social control, relatively little attention has been given to their role in understanding neighborhood rates of crime. At the same time, there is contradictory evidence about the role of social networks, which have been the focus of much research attention. This article builds upon past work to present a model of neighborhood-based institutional social control to address this lack of attention. The model centers on a conceptualization of institutional strength that distinguishes between the dimensions of institutional strength, and the causes and effects of variation in institutional strength

A perfused multi-well bioreactor platform to assess tumor organoid response to a chemotherapeutic gradient.

There is an urgent need to develop new therapies for colorectal cancer that has metastasized to the liver and, more fundamentally, to develop improved preclinical platforms of colorectal cancer liver metastases (CRCLM) to screen therapies for efficacy. To this end, we developed a multi-well perfusable bioreactor capable of monitoring CRCLM patient-derived organoid response to a chemotherapeutic gradient. CRCLM patient-derived organoids were cultured in the multi-well bioreactor for 7 days and the subsequently established gradient in 5-fluorouracil (5-FU) concentration resulted in a lower IC50 in the region near the perfusion channel versus the region far from the channel. We compared behaviour of organoids in this platform to two commonly used PDO culture models: organoids in media and organoids in a static (no perfusion) hydrogel. The bioreactor IC50 values were significantly higher than IC50 values for organoids cultured in media whereas only the IC50 for organoids far from the channel were significantly different than organoids cultured in the static hydrogel condition. Using finite element simulations, we showed that the total dose delivered, calculated using area under the curve (AUC) was similar between platforms, however normalized viability was lower for the organoid in media condition than in the static gel and bioreactor. Our results highlight the utility of our multi-well bioreactor for studying organoid response to chemical gradients and demonstrate that comparing drug response across these different platforms is nontrivial
