Fatal descent from height in New York City

All deaths due to descent from height that underwent autopsy at the Manhattan Office of Chief Medical Examiner of New York City over a two year period (1997-1999) were reviewed. The scene and autopsy findings, psychiatric history, and toxicology results were examined. There were 120 deaths: 77 suicides, 36 accidents, 5 undetermined, and 2 homicides. Psychiatric illness was reported in 86% of suicides. The toxicological detection of psychiatric medications supports the high percentage of psychiatric disease in the suicide group. In the accidental group, the detection of ethanol and illicit drugs was higher (36%) than expected from the case investigation and similar to the suicide group (29%). Accidental falls by women made up fewer than 3% of all manners. Due to the variation in the extent of injuries, it is unwise to attempt to conclude how high a person descended based on the autopsy findings. Descents into water commonly have minimal findings on external examination with marked internal injuries. The methods of investigation and criteria for death certification using the study results are discussed.     

Truancy Intervention Reduces Crime: Results from a Randomized Field Trial

Educational attainment is a fundamental cornerstone to success throughout the life-course. As a result, ensuring that young people remain in school and are not truant is critical. Although the importance of truancy as a risk factor for many adverse outcomes, including crime, has been well-documented, much less methodologically rigorous work has been undertaken to evaluate potentially promising prevention and intervention strategies. This paper uses a randomized field trial method to test how a partnership between police and schools targeting truancy impacts offending in a sample of high-risk truanting young people. We find that the truancy intervention reduces offending and we discuss the implications for practice and directions for future research.     

Judicial Independence: Evidence from a Natural Experiment

In this article, we directly test the presence of judicial independence by examining judicial recess appointees who have later been confirmed by the Senate to full‐time Article III judicial positions. Specifically, we compare the votes of recess‐appointed courts of appeals judges during their temporary appointment tenure with a similar period following Senate confirmation. We find substantial differences in pre‐ and postconfirmation voting, suggesting that the structural protections of the Constitution provide judges a certain amount of independence.     

Students' Fear After Columbine: Findings from a Randomized Experiment

On April 20, 1999, the most deadly act of school violence in the United States occurred at Columbine High School. Public perceptions and media accounts suggested that fear of victimization at school greatly increased after Columbine. The actual response is unknown. The 1999 School Crime Supplement to the National Crime Victimization Survey provides a unique opportunity to study Columbine's effect on students' fear. Experimental conditions were approximated by the NCVS sampling design that randomly allocated the 12- to 18-year-old student-respondents to pre- and post-April 20 groups. Contrary to expectations, students were only slightly more fearful after Columbine. An initial explanation for this finding is explored. As little is known about fear following highly publicized incidents of extreme violence such as Columbine and the terrorist attacks of September 11, 2001, this research provides an essential foundation for further study and theoretical development in this largely-ignored area of fear.     

Phencyclidine: a 5-year retrospective review from the New York City Medical Examiner's Office

We report here a 5-year retrospective review of autopsy cases from the New York City Medical Examiner's Office that demonstrated phencyclidine (PCP) in the blood. There were a total of 138 cases. There were 52 deaths because of mixed drug intoxication: the blood PCP concentrations in these cases ranged from <1 to 598 ng/mL. There were 80 violent deaths in which PCP was quantified in the blood but was unrelated to the cause of death. There were five nonviolent deaths in which PCP exclusively was detected. In four of these, there were preexisting medical conditions that could also have contributed to death. In these, the highest PCP concentration was 361.3 ng/mL, a concentration lower than seven of the individuals in our violent death category. This suggests that lower concentrations may be fatal with comorbid conditions.     

The Relationship Between Crime and Stop,Question, and Frisk Rates in New York City Neighborhoods

The current study builds on prior research in an analysis of the relationship between monthly violent and property crime rates in New York City census tracks and the New York City Police Department’s highly contentious stop, question, and frisk (SQF) policy. We find that higher doses of SQF are associated with small crime reductions generally and specific crime reductions for stops of blacks, Hispanics, and whites. But the way the policy was implemented precludes strong causal conclusions. Now that a federal court has intervened and SQF is undergoing change, the court monitor, New York Police Department, and city officials should partner with researchers in experimental evaluations to determine the optimal mix and dosage of enforcement strategies that safeguard the rights and liberties of citizens while enhancing public safety.     

Evaluating Contemporary Crime Drop(s) in America,New York City,and Many Other Places

This paper describes and evaluates some fundamental facts about the contemporary crime drop, summarizes the major explanations that have been offered for it, and assesses the validity of these explanations in light of observed trends. In contrast with much of the recent literature, we argue that the locus of the crime drop in the 1990s is not wholly consistent with the available data and that while New York City experienced substantial crime decreases, its uniqueness has been exaggerated. We suggest that it is important to partition the crime drop observed in New York City and elsewhere into global and more localized shifts, and we offer some observations about the factors that appear most germane to driving these different dimensions of recent crime drops. We conclude with some suggestions for future inquiry.     

Overview of: “Crime Place and Pollution: Expanding Crime Reduction Options Through a Regulatory Approach”

Research Summary Crime reduction policy has focused almost exclusively on offenders. Recent studies and evaluations show that expanding our policy portfolio to include places may be highly productive. We show that there is considerable research showing that crime is concentrated at a relatively few locations, that high-crime places are stable, that changing places can reduce crime, that displacement is not only far from inevitable but also less likely than the diffusion of crime prevention benefits, and that owners of high-crime places can be held accountable for the criminogenic conditions of their locations. We link these findings to environmental policy, where environmental scientists, economists, and regulators have developed a broad set of regulatory options. The core of this article describes a portfolio of environmental policy instruments directly applicable to crime places. We also discuss major decisions local governments will need to make to implement various forms of regulation, and we list challenges that governments must anticipate in planning for such implementation. We argue that a regulatory approach to crime places has the potential to lower the cost to taxpayers of reducing crime by shifting costs from governments to the relatively few place owners whose actions create crime-facilitating conditions. Policy Implications Taking a regulatory approach to crime places substantially expands the crime policy options under consideration. Regulatory options may increase local governments’ effectiveness at reducing crime while reducing governments’ costs. This is because regulatory approaches have the potential to shift some portion of the financial burden for crime fighting to owners of criminogenic locations. Policy makers can select between means-based anticrime regulations that focus on how place owners manage their locations and ends-based regulations that focus on the number of crimes allowed at places. Both of these approaches contain several alternative regulatory instruments, each with its own set of advantages and disadvantages. Experimenting with various regulatory instruments could lead to the development of a range of new crime reduction policies. In addition, a regulatory approach has implications for the funding of policy research. Means-based regulatory instruments require governments to develop evidence that the means they regulate have the desired impact on crime. Ends-based regulatory instruments shift this burden to the regulated places.

Bodies found in the waterways of New York City

We reviewed the case records for all decedents recovered from the waterways of New York City over a three year period (1997-2000). The epidemiological profile, circumstances, toxicology findings, putrefactive changes, date of recovery, length of immersion, and injuries were examined. There were 123 deaths: 52 suicides, 50 undetermined, 16 accidents, and five homicides. The causes of death included: 97 drownings, 13 undetermined, and 13 other. Of all the floating decedents, 27% were without putrefactive change. All found after two or more weeks of immersion were recovered from November to May. The detection of ethanol and illicit drugs was 53% in the accident, 41% in the suicide, and 33% in the undetermined groups. Detection of ethanol and/or drugs of abuse is not a reliable criterion to distinguish suicide from accident. The identification of the deceased is pivotal for determining the manner of these deaths. Therefore, a great reliance is placed upon the medical investigator and the police (including the missing persons bureau) to determine the circumstances and identification of the decedent.     

Recruitment of female police officers in New York City

As part of a larger study, forty-two female police officers in New York City were asked to articulate their motivations for selecting police work as a career. The reasons given are presented, and comparisons are made with the reasons given in the few other studies of male and female officers. It is felt that a better understanding of the motivations behind this career choice will help the police agencies recruit more effectively and more appropriately select candidates for openings.     

The Effect of Incarceration on Re-Offending: Evidence from a Natural Experiment in Pennsylvania

Objectives

This paper uses a sample of convicted offenders from Pennsylvania to estimate the effect of incarceration on post-release criminality.

Methods

To do so, we capitalize on a feature of the criminal justice system in Pennsylvania—the county-level randomization of cases to judges. We begin by identifying five counties in which there is substantial variation across judges in the uses of incarceration, but no evidence indicating that the randomization process had failed. The estimated effect of incarceration on rearrest is based on comparison of the rearrest rates of the caseloads of judges with different proclivities for the use of incarceration.

Results

Using judge as an instrumental variable, we estimate a series of confidence intervals for the effect of incarceration on one year, two year, five year, and ten year rearrest rates.

Conclusions

On the whole, there is little evidence in our data that incarceration impacts rearrest.     

The dragon breathes fire: Chinese organized crime in New York City

Although it is widely acknowledged that Chinese businesses are victims of extortion by Asian youth gangs, there is no reliable information to examine the patterns and social processes of the problem. This paper explores the structure of extortion and other forms of victimization based on surveys of (N=603) Chinese-owned businesses in three Chinatown neighborhoods in New York City. It focuses on the nature of Chinese crime groups, social contexts of gang extortion, social processes of victimization, and merchants' compliance or resistance to gang demands. Finally, the paper discusses the problems and prospects of Chinese criminality in America.Support for this research was provided by Grant 89-IJ-CX-0021 from the National Institute of Justice.

Area Differences and Time Trends in Crime Reporting: Comparing New York with Other Metropolitan Areas

Police measures of crime are shaped by victims’ decisions to notify the police. To obtain a better understanding of US crime trends, this study uses the National Crime Victimization Survey to examine geographic differences and temporal trends in crime reporting in New York and other metropolitan areas for the period 1979-2004. We find that net of crime characteristics and survey methodology, the New York metropolitan area showed fewer increases in crime reporting than did other metropolitan areas. These divergent trends suggest that the real differences in the drop of nonlethal violence between New York and other areas may have been smaller than those indicated by police-based crime statistics. We also find that from the early 1990s to 2004, New York showed a sharp decrease in the likelihood of victims perceiving that “police wouldn’t help.” This trend suggests that police reforms in New York City have not resulted in more victims using police-related reasons to explain their nonreporting behavior. Instead, researchers need to develop a broader theoretical framework (not an exclusive focus on police actions) to understand how police- and nonpolice-related factors may explain the geographic variation in the trends of reporting observed in this study.     

Identifying Classes of Explanations for Crime Drop: Period and Cohort Effects for New York State

Objective

This paper advances current understanding of the contemporary crime drop by focusing on the changes in the age distribution of arrests from 1990 to 2010. Using the New York State Computerized Criminal History (CCH) file, which tracks every arrest in the state, we apply standard demographic methods to examine age-specific arrest rates over time. We test whether the 25 % drop in the felony arrest rate can be best explained by period or cohort effects with special attention to how the phenomenon varies across crime types and regions within the state.

Methods

Following the analytic approach of O’Brien and Stockard (J Quant Criminol 25(1):79–101, 2009), we fit the age–period–cohort (APC) model using the generalized inverse matrix, which creates an estimable model. We partition the model variation into each factor by subtracting the variation of the two-factor model from the variation of the three-factor model to provide a direct comparison of the two different classes of explanations for crime drop: period and cohort.

Results

Our analysis supports a cohort explanation over a period explanation. Controlling for the (substantial) variation due to age, the cohort effect accounts for twice as much of the remaining variation as the period effect. Specifically, the drop in arrest rates is concentrated in more recent birth cohorts across all ages. Although we found statistically significant age–period interaction effects for the younger age group (ages 16–20) in 1990 and 1995, the cohort effect was still a much stronger predictor of felony arrest rates than the period explanation, even with the age–period interaction.

Conclusions

The current study reports that the overall drop in felony arrest rates from 1990 to 2010 is mostly due to decreased arrests among those who were born after 1970 rather than a universal drop across different age groups. We discuss but do not test two potential explanations—the legalization of abortion and the ban on leaded gasoline—for the underlying factors associated with a different criminal propensity among birth cohorts.
