A Natural Experiment in Reform: Analyzing Drug Law Policy in New York City, New York, Quantitative Data, 2006-2012 (ICPSR 34883)

Released/updated on: 2020-09-30

Geographic coverage: New York City, United States, New York (state)

Time period: 2006-10-01--2012-11-30

On January 1, 2011, the Vera Institute of Justice (Vera) launched "A Natural Experiment in Reform: Analyzing Drug Law Policy in New York," which was funded by the National Institute of Justice, and conducted by Vera, with the John Jay College of Criminal Justice at the City University of New York, and the School of Criminal Justice at Rutgers University. This study sought to analyze the effects of recent changes in drug offense sentencing laws in New York State (NYS) and chronicle New York City's experience with drug law reform (DLR). This includes changes in sentencing outcomes for felony drug cases, reoffending, and cost implications, with the hope of informing NYS policy makers, and provide other states across the nation with research to inform their own DLR efforts.

Specifically, this study revolves around the following objectives: 1) describe how the DLR is reflected in actual sentencing outcomes and the extent to which practices of judges, lawyers, and defense attorneys have shifted in response to the reforms; 2) investigate how treatment diversion impacts reoffending and 3) analyze the cost implications of changing drug law sentencing policies. Researchers analyzed administrative data to describe the impacts of reforms on sentencing decisions, collected New York City arrest data for drug felonies between October 1, 2006 and September 30, 2011, and evaluated outcome data measuring recidivism and costs between pre and post DLR periods.

Numerous variables tracking offenders' progress through the criminal justice system were collected including admission to the Drug Treatment Alternative to Prison (DTAP) program, arrest and disposition jurisdictions, charges, sentencing, and drug court screening and admission. Arrestees' criminal history and rearrest figures, as well as their sex, race, and ethnic demographics were collected also.

Testing the Effects of Selected Jury Trial Innovations on Juries' Comprehension of DNA Evidence in New Castle County, Delaware, 2003 (ICPSR 4356)

Released/updated on: 2006-01-06

Geographic coverage: United States, Delaware

Time period: 2003-10-14--2003-12-16

This study tested whether the use of selected jury trial reforms enhanced jurors' understanding of complex and challenging scientific evidence presented during a criminal trial. The study examined the use of several jury reform techniques using a controlled mock jury approach in which mock juries composed of jury pool members watched a videotaped armed robbery trial featuring conflicting expert testimony about mitochondrial DNA (mtDNA) evidence. A total of 480 mock jurors were randomly assigned to eight-person juries and to one of the six conditions in the experiment. Ten mock juries were run in each of the six conditions (No Innovations, Note Taking, Question Asking and Note Taking, DNA Checklist and Note Taking, Jury Notebook and Note Taking, and All Innovations). At various points throughout the study (before the trial, after watching the videotaped trial, and after reaching a verdict), mock jurors were asked to complete questionnaires to gauge their understanding of mtDNA and the mtDNA evidence presented during the trial. They were also asked if and how the use of the jury trial innovations helped in their understanding of the mtDNA evidence. Specific variables contained in the study include demographic variables of the mock jurors, including their math and science background, mock jurors' views of science, their understanding of mtDNA, their perceptions of the reliability of different types of evidence, and the credibility of the prosecutor, defense attorney, detective, eyewitness, defendant, and expert witnesses, and whether the mock jurors favor or oppose the various innovations.

Youth Justice Policy Environments and Their Effects on Youth Confinement Rates, United States, 1996-2016 (ICPSR 37618)

Released/updated on: 2020-12-17

Geographic coverage: United States

Time period: 1996-01-01--2016-01-01

This study was conducted to address the dropping rates in residential placements of adjudicated youth after the 1990s. Policymakers, advocates, and reseraches began to attirbute the decline to reform measures and proposed that this was the cause of the drop seen in historic national crime. In response, researchers set out to use state-level data on economic factors, crime rates, political ideology scores, and youth justice policies and practices to test the association between the youth justice policy environment and recent reductions in out-of-home placements for adjudicated youth.

This data collection contains two files, a multivariate and bivariate analyses. In the multivariate file the aim was to assess the impact of the progressive policy characteristics on the dependent variable which is known as youth confinement. In the bivariate analyses file Wave 1-Wave 10 the aim was to assess the states as they are divided into 2 groups across all 16 dichotomized variables that comprised the progressive policy scale: those with more progressive youth justice environments and those with less progressive or punitive environments. Some examples of these dichotomized variables include purpose clause, courtroom shackling, and competency standard.
