The future of crime data

Criminology lacks sufficient data for many types of crime that are of great concern to society. This lack of data poses significant problems for determining whether resources are adequate for responding to these crimes or whether programmatic, legislative, or target-hardening efforts to prevent or reduce their occurrence are effective. Inadequate data about crime also produces a selective and incomplete narrative about crime that makes it easier for political and vested interests to exploit public concerns about crime for their own ends. In this address, I discuss what is needed to resolve these gaps and the ways in which criminologists can support a significant expansion of the crime data infrastructure. Such work is necessary to help ensure the future relevance of criminological research.     

Convenient and Inconvenient Truths in Family Law: Preventing Scholar‐Advocacy Bias in the Use of Social Science Research for Public Policy

This is the second of two articles on the risks of advocacy bias in the reporting of research findings when boundaries are blurred between social science research and advocacy in the pursuit of public policy. In the first article we identify common ways in which social science researchers and reviewers of research—wittingly or unwittingly—can become advocates for ideological positions and social policies at the expense of being balanced reporters of research evidence. The first article discusses the difference between truth in social science and truth in law and identifies a range of scholar‐advocacy strategies that bias research evidence, illustrated by recent debates about overnight parenting of infants and toddlers. In this second article we show how biased research evidence by scholar advocates results in increased confusion and controversy that diminishes the credibility of all parties and stalemates progress in the field, using a case illustration of intimate partner violence in family court. We also show how adherence to scientific methods prevents the misuse of research and suggest a number of collaborative, integrative measures that can help transcend the adversarial stalemate. In a look to the future we consider some unbiased, standardized ways of assessing the strength and generalizability of research evidence.     

STATE URBAN POLICY: "New" Federalism In Virginia, New Jersey and Florida

The recent rediscovery of federalism has left the nation's governors with expanded responsibility and limited federal support. In return, they were promised greater fiscal flexibility, a real partnership in program design, and protection from unfunded mandates. However, states seem unwilling to offer the same guarantees to their cities that they sought from the federal government, even as they expand city responsibilities and limit state aid. This paper explores the extent to which Virginia, New Jersey and Florida have provided the fiscal flexibility and partnership, except in the area of economic development, but the diminished fiscal capacity of some distressed communities relative to their suburban counterparts render them unable to benefit from such efforts.     

A Comparison of Four Presumptive Tests for the Detection of Blood on Dark Materials

Detection of blood on dark materials is difficult for crime scene examiners so presumptive tests are used to assist. This study compared the ability of luminol, leuko crystal violet, tetramethylbenzidine, and Combur Test®E to detect whole, diluted blood (1:100) and a key‐shaped blood transfer stain (1:10), on dark cotton sheeting, tea towel, socks, synthetic carpet, and car mats. Powdered bleach was used to evaluate specificity of the blood detection tests. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall misclassification rate (OMR) assessed the quality of the blood tests. Luminol was the preferred test for diluted blood having the highest sensitivity (79%–96%), NPV (66%–93%), and the lowest OMR (3%–15%). Luminol was also found to be most efficient with a testing time on 25 items of 2 h 50 min compared with up to 8 h. Overall, luminol was the most effective method, also providing information on bloodstain patterns.
