Objectives

This article examines the timing of change in criminal offending relative to entrance into parenthood, in light of four competing theoretical frameworks (social control, routine activities, strain and cognitive transformation). Moreover, it analyzes whether criminal developments over time are gender- or country-specific.

Methods

Using samples of men and women at risk of offending in the Netherlands and Norway, this study investigates monthly changes in offending probabilities around the time of first birth (5 years before, 5 years after). The implemented smoothing splines technique allowed for a flexible exploration of changes in offending probabilities for both pre-childbirth and post-childbirth periods.

Results

The results show that the probabilities to offend decline ahead of childbirth for all individuals analyzed. The post-childbirth period is characterized by increases in offending probabilities. However, in these overall trends, the exact timing and magnitude of change differs by gender and country of residence.

Conclusions

The results offer partial support for the cognitive transformation hypothesis because offending rates decline before childbirth. The post-childbirth period converges with assumptions of the strain theory (for males in particular) because offending probabilities increase in this period. Additional analysis investigating changes in property offending shows that economic strain does not explain the upward trend of the overall offending after childbirth.

Objectives

To evaluate whether the 1990s crime drop reflects a decrease in offending prevalence (the fraction of the population engaged in crime), offending incidence (the frequency of offending among active criminals), or some combination of the two.

Methods

We use individual-level longitudinal data on adolescent offending patterns from the Pittsburgh Youth study (PYS), integrating information from the youngest and oldest cohorts to compare offending among 17–18 year old males at the beginning and end of the 1990s. Logistic and negative binomial regression models are estimated to assess whether there are significant differences in offending prevalence and incidence during the 1990s.

Results

The reduction in property crime rates in the PYS sample during the 1990s can be attributed to declines in both offending prevalence and incidence. The overall decline in serious violence during the 1990s for the full sample was primarily the result of a falloff in prevalence. However, for black youth our results indicate significant reductions in both the prevalence and incidence of serious violence. We did not detect a significant difference in illegal drug sales during the period.

Conclusions

Using longitudinal data on individuals to decompose aggregate crime trends into changes in the prevalence and incidence of offending offers insights into the nature of the 1990s crime drop that cannot be discerned from aggregate crime data. Future research should build on the current study by examining the specific mechanisms that influence change over time in crime prevalence, incidence, or both.

Objectives

We seek evidence for economic and social mechanisms that aim to explain the relationship between employment and crime. We use the distinctive features of social welfare for identification.

Methods

We consider a sample of disadvantaged males from The Netherlands who are observed between ages 18 and 32 on a monthly time scale. We simultaneously model the offending, employment and social welfare variables using a dynamic discrete choice model, where we allow for state dependence, reciprocal effects and time-varying unobserved heterogeneity.

Results

We find significant negative bi-directional structural effects between employment and property crime. Robustness checks show that only regular employment is able to significantly reduce the offending probability. Further, a significant uni-directional effect is found for the public assistance category of social welfare on property offending.

Conclusion

The results highlight the importance of economic incentives for explaining the relationship between employment and crime for disadvantaged individuals. For these individuals the crime reducing effects from the public assistance category of social welfare are statistically equivalent to those from employment, which suggests the importance of financial gains. Further, the results suggest that stigmatizing effects from offending severely reduce future employment probabilities.

Objective

Mounting evidence reveals that foreign-born, first generation immigrants have significantly lower levels of criminal involvement compared to their US-born, second and third-plus generation peers. This study investigates whether this finding is influenced by differential crime reporting practices by testing for systematic crime reporting bias across first, second, and third-plus generation immigrants.

Methods

This study draws on data from the Pathways to Desistance Study, a longitudinal investigation of the transition from adolescence to young adulthood among a sample of serious adolescent offenders. Self-reported and official reports of arrest are compared longitudinally across ten waves of data spanning 7 years from adolescence into young adulthood for nearly 1300 adjudicated males and females.

Results

This study reveals a high degree of correspondence between self-reports of arrest and official reports of arrest when compared within groups distinguished by immigrant generation. Longitudinal patterns of divergence, disaggregated by under-reporting and over-reporting, in self- and official-reports of arrest indicated a very high degree of similarity regardless of immigrant generation. We found no evidence of systematic crime reporting bias among foreign-born, first generation immigrants compared to their US-born peers.

Conclusions

First generation immigrants are characterized by lower levels of offending that are not attributable to a differential tendency to under-report their involvement in crime.

Objectives

To examine the independent and interdependent roles of baseline religious support during incarceration and within-individual changes in religious support on recidivism during the prisoner reentry process.

Methods

Using data from the Serious and Violent Offender Reentry Initiative, cross-lagged dynamic panel models are used to examine the respective roles of baseline differences and within-individual changes in religious support on two variety indices encompassing substance use and criminal offending while simultaneously controlling for pre-incarceration levels of substance use and offending.

Results

Findings show that within-individual increases in religious support protect against substance use post-release, while baseline levels of religious support do not significantly influence substance use. Additionally, baseline levels of religious support fail to condition this relationship. Findings assessing criminal offending demonstrate that baseline religious support and within-individual changes in religious support fail to relate to offending independently. However, an interaction term reveals that the combination of the two relates to significantly lower levels of offending post-release.

Conclusions

Findings offer encouragement for those involved in the work of providing religious support to ex-offenders in the community, reaffirming that tailoring support programs to the religious or spiritual ways individuals make meaning in their lives can improve reentry outcomes. Methodologically, failing to distinguish between baseline levels of religious support and post-release changes in religious support fails to capture the complexity of religiosity on the reentry process.

Objectives

To examine the extent to which there are differences in the developmental course of offending among individuals with maltreatment histories, compared to nonmaltreated controls, and whether these patterns vary for males and females.

Methods

This paper uses data from a longitudinal study in which abused and neglected children (N = 908) were matched with non-maltreated children (N = 667) and followed prospectively into adulthood. Group-based trajectory modeling was conducted using official criminal history records collected through mean age 51. Patterns of criminal offending were first considered for the whole sample, with abuse status and sex included as time-stable covariates, and then separately by subgroup (control females, maltreated females, control males and maltreated males).

Results

Analyses revealed that a three-group model provided the best fit (nonoffenders, low-level chronic offenders, mid-level chronic offenders) for the overall sample. Child maltreatment and sex were significant predictors, with offenders more likely to be male and abused/neglected, compared to non-offenders. Separate analyses for the four subgroups revealed some similarities across groups in the characterization of offending trajectories, although trajectories for abused/neglected females differed significantly from trajectories for control females. Additional analyses suggest that desistance from offending may be largely a function of incapacitation due to early death, rather than imprisonment.

Conclusions

These new analyses provide evidence that child maltreatment affects patterns of offending and that there is an impact on females and males, although the impact differs by gender. Future research should build on this work by examining the mechanisms through which child maltreatment leads to differential patterns of offending throughout the life course.

Objectives

This paper tests the economic theory of criminal behavior. Specifically, it looks at “the carrot” side of the theory, studying how thieves react to changes in monetary gains from crime.

Methods

Using a unique crime-level dataset on metal theft in the Czech Republic, we study thieves’ behavior in a simple regression framework. We argue that variation in metal prices represents a quasi-experimental variation in gains from crime. It is because (1) people steal copper and other nonferrous metals only to sell them to scrapyard and (2) prices at scrapyards are set by the world market. This facilitates causal interpretation of our regression estimates.

Results

We find that a 1% increase (decrease) in the re-sale price causes metal thefts to increase (decrease) by 1–1.5%. We show that the relationship between prices and thefts is very robust. Moreover, we find that thieves’ responses to price shocks are rapid and consistent.

Conclusion

Our results are in line with the economic model of crime, wherein criminal behavior is modeled as a rational agent’s decision driven by the costs and benefits of undertaking criminal activities. Our estimates are also consistent with recent results from the United Kingdom, suggesting these patterns are more general.

Objectives

While many criminological theories posit causal hypotheses, many studies fail to use methods that adequately address the three criteria of causality. This is particularly important when assessing the impact of criminal justice involvement on later outcomes. Due to practical and ethical concerns, it is challenging to randomize criminal sanctions, so quasi-experimental methods such as propensity score matching are often used to approximate a randomized design. Based on longitudinal data from the Cambridge Study in Delinquent Development, the current study used propensity score matching to investigate the extent to which convictions and/or incarcerations in the first two decades of life were related to adverse mental health during middle adulthood.

Methods

Propensity scores were utilized to match those with and without criminal justice involvement on a wide range of risk factors for offending.

Results

The results indicated that there were no significant differences in mental health between those involved in the criminal justice system and those without such involvement.

Conclusions

The results did not detect a relationship between justice system involvement and later mental health suggesting that the consequences of criminal justice involvement may only be limited to certain domains.

Objectives

Effects of place-based criminal justice interventions extend across both space and time, yet methodological approaches for evaluating these programs often do not accommodate the spatiotemporal dimension of the data. This paper presents an example of a bivariate spatiotemporal Ripley’s K-function, which is increasingly employed in the field of epidemiology to analyze spatiotemporal event data. Advantages of this technique over the adapted Knox test are discussed.

Methods

The study relies on x–y coordinates of the exact locations of stop-question-frisk (SQF) and crime incident events in New York City to assess the deterrent effect of SQFs on crime across space at a daily level.

Results

The findings suggest that SQFs produce a modest reduction in crime, which extends over a three-day period. Diffusion of benefits is observed within 300 feet from the location of the SQF, but these effects decay as distance from the SQF increases.

Conclusions

A bivariate spatiotemporal Ripley’s K-function is a promising approach to evaluating place-based crime prevention interventions, and may serve as a useful tool to guide program development and implementation in criminology.

Objective

To assess whether joblessness affects the commission of serious property crime.

Methods

We studied serious property crime, applying a case–control design to nationally representative samples of (a) known serious property crime offenders and (b) nonoffenders. This was done by comparing a national sample of prison inmates convicted of robbery or burglary (the “cases”) with a general sample of the U.S. adult population (the “controls”). In contrast to prior individual-level research, the study sample included substantial numbers of serious offenders, and provided a formal basis for generalizing the findings to the U.S. adult population. We differentiated five labor force statuses: (1) unemployed (according to the official government definition), (2) underemployed, (3) out of the labor force for widely socially accepted reasons (OLFL), (4) out of the labor force for reasons not widely accepted (OLFN), and (5) fully employed.

Results

We found that when these distinctions are made, people are not more likely to engage in burglary or robbery when they are either completely unemployed or underemployed according to the official definitions. Instead, it is being out of the labor force for reasons not widely accepted as legitimate that is significantly and positively related to serious property offending.

Conclusions

The results suggest that offending among jobless persons may reflect preexisting differences in criminal propensity among those who stay out of the labor force, rather than effects of joblessness per se. Part-time work is associated with significantly less property crime, perhaps because the willingness to accept even part-time jobs serves as an indicator of commitment to pro-social attitudes.

Objectives

This study examines sentencing patterns for environmental crimes and tests the assumption that “green” offenders receive more lenient treatment from criminal courts than non-environmental offenders.

Methods

We present two sets of analyses. First, we present an empirical portrait of environmental felony offenses convicted in a single state (Florida) over a fifteen-year period and the resulting criminal sanctions. Second, we use a precision matching analysis to assess whether environmental offenders receive more lenient treatment when compared to non-environmental offenders with the same characteristics and offense severity scores.

Results

Findings indicate that an overall small percentage of felony convictions in state courts stem from environmental crimes. We also find that punishments for environmental crimes are more lenient than sanctions assigned to comparable non-environmental offenses when the environmental crime is ecological, but that punishments are sometimes harsher when the environmental crime involves animals.

Conclusions

The findings provide general support for the argument that courts and other formal institutions of social control treat environmental crimes more leniently than non-environmental crimes. This paper also raises important questions about citizen and state actors’ perceptions of crimes against the environment and, more generally, about the ways in which theories of court sentencing behaviors apply to environmental crime sanctioning decisions.

Objectives

This study examines the effectiveness of foot patrol in violent micro-places. A large urban police department deployed foot patrol in micro-places (hot spots) for a period of 90 days for two shifts each day. Our objective is to determine whether this activity impacted violent crime in these hot spots and whether spatial displacement of crime occurred.

Methods

Eight eligible foot beat locations were set by examining crime rates for previous years in order to identify micro-places of high criminal activity. We employed a quasi-experimental design comparing the four treatment to the four control areas, estimating panel-specific autoregressive models for 30 weeks prior to and 40 weeks after the treatment.

Results

Time series models revealed statistically significant reductions in violent crime in the micro-places receiving foot patrol treatment, while no such reductions were observed in the control areas. The deterrent effect, however, was short and dissipated quickly. Control areas did not experience any crime prevention benefit during this time period. No evidence of crime displacement to spatially contiguous areas was detected.

Conclusions

This contributes to the growing body of knowledge that focused police strategies within hot spots impact violent crime. Specifically, the implementation of foot patrol in high crime hot spots led to measurable reductions in aggravated assaults and robberies, without displacing crime to contiguous areas.

Objectives

Given the growing reliance on longitudinal self-report data for making causal inferences about crime, it is essential to investigate whether the within-individual change in criminal involvement exists and is not a measurement artifact driven by attrition or survey fatigue—a very real possibility first identified by Lauritsen (Soc Forces 77(1):127–154, 1998) using the National Youth Survey (NYS). The current study examines whether the same threats to the validity of within-individual change in criminal involvement exist in the National Longitudinal Survey of Youth 1997 cohort (NLSY97).

Methods

We first estimate cohort-specific growth curve models of general crime, arrest, and substance use, and then test the difference between the age–crime curves of adjacent cohorts. We take a general approach to test cohort differences in the growth curve models, which advances the existing method separately modeling for each pair of adjacent cohorts. To explore the sources of cohort differences, we also estimate separate growth curve models by individual crime item and by demographic group.

Results

We document non-standard cohort differences between the age–crime curves of adjacent cohort pairs that are consistent with the findings of Lauritsen (1998) on measures of self-reported offending. However, the size of the cohort effects in the NLSY97 is substantially smaller than those in the NYS. We also found that the cohort effects were only evident in some of the survey items. Moreover, we did not identify any similar cohort issues in the longitudinal measure of arrest.

Conclusions

The findings of cohort effects localized in a certain crime items and demographic groups may mitigate concerns over the limited validity of longitudinal self-report data. We discuss how the survey techniques used in the NLSY97 might explain our findings and suggest an area of future study to explicate remaining cohort differences.

Objectives

Investigate the spatial concentrations and the stability of trajectories for disaggregated crime types on street segments and intersections in Vancouver, Canada.

Methods

A longitudinal analysis of 16 years of crime data using street segments and intersections as the units of analysis. We use the k-means non-parametric cluster analysis technique considering eight crime types: assault, burglary, robbery, theft, theft of vehicle, theft from vehicle, other, and total crime.

Results

The overall results for the individual crime types versus overall crime are similar: crime is highly concentrated regardless of crime type, most street segment and intersection trajectories are stable over time with the others decreasing, and most decreasing trajectories are in the same general areas. However, there are notable differences across crime types that need to be considered when attempting to understand spatial pattern changes and implement crime prevention initiatives.

Conclusions

The law of crime concentration at places holds in Vancouver, Canada for disaggregated crime types in the context of spatial concentrations and their stability over time. However, notable differences exist across crime types that should be accounted for when developing theory or policy.

Objectives

Inflation is conspicuous by its absence from recent research on crime and the economy. We argue that price inflation increases the rate of crimes committed for monetary gain by fueling demand for cheap stolen goods.

Methods

The study includes inflation along with indicators of unemployment, GDP, income, consumer sentiment, and controls in error correction models of acquisitive crime covering the period from 1960 to 2012. Both short- and long-run effects of the predictors are estimated.

Results

Among the economic indicators, only inflation has consistent and robust short- and long-run effects on year-over-year change in the offense types under consideration. Low inflation helps to explain why acquisitive crime did not increase during the 2008–2009 recession. Imprisonment rates also have robust long-run effects on change in acquisitive crime rates.

Conclusions

Incorporating inflation into studies of crime and the economy can help to reduce the theoretical and empirical uncertainty that has long characterized this important research area in criminology.

Objectives

To describe how social scientists, criminal justice practitioners, and administrative agencies collected administrative data to follow-up a criminological experiment after two decades. To make recommendations that will guide similar long-term follow-ups.

Methods

A case study approach describes the processes of and sociological benefits to collecting administrative data to assess criminal justice and life-course outcomes.

Results

While maintaining experimental integrity, we developed, executed, and verified processes to retrieve arrest, mortality, and residential data for the experimental subjects, which enabled us to complete the longest ever follow-up of a criminal justice experiment.

Conclusions

When experiments have policy implications, administrative data may be preferable to survey data for assessing primary effects. Successful social science research can be conducted in conjunction with multiple administrative agencies.

Objectives

The purpose of this study was to test the “worst of both worlds” hypothesis and the risk principle in a sample of drug-involved offenders enrolled in the Breaking the Cycle (BTC) demonstration project, an intensive drug intervention implemented in Birmingham, Alabama, Jacksonville, Florida, and Tacoma, Washington.

Methods

A group of 1081 drug-involved offenders enrolled in BTC were compared to 934 drug-involved offenders (pre-BTC) who processed through the regular court system of each city 1 year prior to implementation of BTC. Participants from both groups were divided into risk levels based on scores from the Addiction Severity Index (ASI) Drug (D) and Legal (L) scales. Individuals who scored at or above the mean on both the ASI-D and ASI-L were identified as high risk, individuals who scored at or above the mean on either the ASI-D or ASI-L but not both were identified as moderate risk, and individuals who scored below the mean on both the ASI-D and ASI-L were identified as low risk.

Results

Consistent with the risk principle, high-risk BTC participants displayed significant improvements in subsequent drug problem days, criminal offending, and days spent in jail relative to high-risk pre-BTC participants. There was no apparent benefit of BTC enrollment for moderate- and low-risk participants.

Conclusions

These results indicate that drug–crime comorbidity can be used to assess risk and that individuals identified as high risk are more likely to benefit from higher-intensity forms of intervention than moderate- or low-risk individuals.

Objectives

A broad research literature in criminology documents key aspects of how criminal offending develops and changes over the life span. We contribute to this literature by showcasing methods that are useful for studying medium-term patterns of subsequent criminal justice system involvement among a sample of serious adolescent offenders making the transition to early adulthood.

Methods

Our approach relies on 7 years of post-enrollment follow-up from the Pathways to Desistance Study. Each person in the study was adjudicated delinquent for or convicted of one or more relatively serious offenses during adolescence. Their local jurisdiction juvenile court petition records and their adult FBI arrest records were systematically searched.

Results

We estimate in-sample 7 year recidivism rates in the 75–80 % range. Our analysis also provides recidivism rate estimates among different demographic groups within the sample. Extrapolated long-term recidivism rates are estimated to be on the order of 79–89 %.

Conclusions

The Pathways data suggest that recidivism rates of serious adolescent offenders are high and quite comparable to the rates estimated on other samples of serious offenders in the extant literature. Our analysis also reveals a pattern of heightened recidivism risk during the earliest months and years of the follow-up period followed by a steep decline.

Measuring the Spatial and Temporal Patterns of Police Proactivity   总被引:1,自引:0,他引:1  

Objectives

To measure where officers engage in proactive, self-initiated activities, how much time they spend being proactive, and whether their proactive activities coincide with crime patterns.

Methods

This study uses Andresen’s Spatial Point Pattern Test to compare the spatial similarity between police proactivity and crime, as well as regression modeling to explore the relationship between proactivity and crime and the time spent on proactivity and crime.

Results

In the jurisdiction examined, high levels of proactivity are noted. This proactive activity is more likely to occur in places where crime is most concentrated. Additionally, the number of proactive calls and the proactive time spent per crime-and-disorder call remain high and stable across spatial scales. For each crime call received at a street block, police initiated 0.7 proactive activities and spent approximately 28 min carrying out proactive works.

Conclusions

This study develops a way of measuring proactive activity by patrol officers using calls for service data. We find that not only do officers in this jurisdiction exhibit higher levels of proactivity to prevent crime (compared to reacting to crime), but they also do so in targeted, micro-place ways. Agencies may consider using similar techniques to gauge the levels of proactivity in their agencies if proactive activity is a goal.

Objectives

People are hesitant to fully support reintegration efforts (e.g., opportunities to receive psychological counseling, career counseling, job training, housing assistance, educational opportunities, financial compensation) to help exonerees wrongfully convicted of a crime. However, underlying reasons motivating people’s hesitancy remain unaddressed. This research examined the influence of being wrongfully convicted of a race stereotypic-consistent crime on people’s judgments of exonerees’ culpability and willingness to support reintegration programs.

Method

Using an experimental design, participants were randomly assigned to read a news story that depicted an African-American or White male who was exonerated after being wrongfully convicted of assault or embezzlement. Participants then offered their culpability judgments (i.e., their belief in the exoneree’s guilt and confidence in that belief) and willingness to support reintegration services.

Results

Participants were less confident of the exoneree’s innocence and less supportive of psychological counseling services when the exoneree was a White, compared to African-American, male wrongfully convicted of the race stereotypic-consistent crime of embezzlement. An exploratory conditional mediation analysis indicated that less confidence in the exoneree’s innocence after being wrongfully convicted of a race stereotypic-consistent crime was, in turn, associated with people’s hesitancy to support psychological counseling for the exoneree.

Conclusions

Basic and applied implications to overcome people’s hesitancy to support reintegration efforts for exonerees are discussed.
