Using National Incident-Based Reporting System Data for Strategic Crime Analysis

The utility of the National Incident-Based Reporting System (NIBRS) forstrategic crime analysis has yet to be explored. The NIBRS represents anadvancement over existing reporting systems and possesses considerableutility to frontline law enforcement with respect to strategic crimeanalysis. This paper discusses the utility of the NIBRS for identifyinglocal and regional trends in narcotics related offenses. As an example, weselected four localities from the 1997 Virginia NIBRS data to examine trendsin the sale/distribution and possession of narcotics. Our analysis showsthat the NIBRS provides significantly more incident-related detail than hasheretofore been available for strategic crime analysis at the regional orstate level. Moreover, the NIBRS provides neighboring communities theopportunity to compare information on emerging crime patterns and criminalenterprises which extend beyond local boundaries. Finally, enhancing localreporting compliance by highlighting the strategic utility of the data tolocal law enforcement will ultimately ensure the quality of the data set,which can then be employed by larger entities as well as criminal justiceresearchers for policy development and planning.     

Victims and Offenders in Two Crime Statistics Programs: A Comparison of the National Incident-Based Reporting System (NIBRS) and the National Crime Victimization Survey (NCVS)

The National Incident-Based Reporting System (NIBRS) overcomes a basiclimitation of the traditional summary Uniform Crime Reporting program (UCR)by collecting victim information. Using this new victim information tocompare National Crime Victimization Survey (NCVS) and NIBRS results, wefind some similarities as well as some differences in the characteristics ofvictims and offenders suggested by the two programs. Similarities appear inthe proportions of men and women involved as victims and offenders forrobbery and assault. Comparisons are more difficult and the proportions lesssimilar for property offenses. Nevertheless, the results suggest that whenthe NIBRS is fully developed, it will be an important source of informationon the characteristics of both victims and offenders. Even before theredesigned program is fully implemented, one of the most important featuresof NIBRS reports will be their ability to provide local area victimizationinformation. In addition, the NIBRS will provide much more information onarrests and the characteristic of offenders than any existing program.     

Using the National Incident-Based Reporting System (NIBRS) to Test Estimates of Arrestee and Offender Characteristics

National-Incident Based Reporting System (NIBRS) information for 1993 iscompared with two other sets of homicide data to assess the acuracy ofprocedures for estimating age-, sex-, and race-specific arrest counts fromtraditional Uniform Crime Report (UCR) data. The simultaneous age, race, andsex characteristics of offenders provided in the NIBRS arrest and offender segmentsare compared with estimates of the same characteristics derived from summaryUCR arrest data. The results suggest that using UCR marginal totals toestimate arrest counts by race and sex produces reasonably accurateestimates of the number of black and nonblack male arrests for murder andother offenses. Estimates of arrests of females by race and sex are lessaccurate, probably because of the relatively small number of arrests ofwomen and girls. Estimating male arrest counts for specific age groups alsoproduces reasonably accurate estimates. The results suggest that previousresearch employing such estimates may have been misleading in the estimatesof female arrests by race but accurate in the estimates of male arrests byrace. Although the use of summary UCR-based estimates in futurecross-sectional research will become increasingly unnecessary as the NIBRSreplaces the current UCR program, time series research designs on arrest andcrime trends will continue to require estimates.     

The National Incident-Based Reporting System: Research and Policy Applications

The National Incident-Based Reporting System (NIBRS) offers a new source ofdata for measuring crime. Though far from national in coverage, NIBRS datacan address research and policy questions outside the scope of the UniformCrime Reports and the National Crime Victimization Survey. Comparisons ofthe three sources of crime data are presented, with particular emphasis onwhat can be learned from incident-based police data that cannot be learnedfrom other sources. Like all data on crime, the NIBRS is subject to variousproblems with validity and measurement error. Two general categories of suchproblems are discussed: those evident in the design of the NIBRS and thoselinked to more general issues in the organizational production of data.     

Community Variation in Crime Clearance: A Multilevel Analysis with Comments on Assessing Police Performance

We use data from the Province of Quebec to examine how the characteristics of a crime and the community context in which it occurs affect the likelihood that it will be cleared by the police. Based on a sample of 362,295 crime incidents clustered in 93 communities, multilevel analyses reveal that the police are more likely to clear crimes in small communities than in large urban areas and in communities with greater levels of poverty. Workload is not very important, having only a slight effect on the clearance of misdemeanors. The fact that offenders are much more likely to evade the law in some communities than others may have important implications for deterrence. Two methods to improve the evaluation of police departments at crime clearance are also proposed.

Economic Conditions, Deterrence and Juvenile Crime: Evidence from Micro Data

This article investigates the determinants of criminal activityamong juveniles in the United States. It uses a survey of U.S.high school students conducted in 1995, which provides detailedinformation on offenses; personal, family, and neighborhoodcharacteristics; as well as deterrence measures. The determinantsof selling drugs and committing assault, robbery, burglary,and theft are analyzed separately for males and females. Theresults provide some evidence that juveniles respond to incentivesand sanctions. Employment opportunities and policies designedto increase the probability of arrest may be effective toolsfor reducing juvenile crime.     

Trends in Adult Suicides in New Mexico: Utilizing Data from the New Mexico Violent Death Reporting System*

Abstract: Although many suicide prevention programs focus on youth suicides, data indicate the vast majority of suicides occur among adults (18–64 years). In 2005 New Mexico joined the Centers for Disease Control and Prevention’s National Violent Death Reporting System, collecting data on suicides, homicides, and unintentional firearm fatalities to better inform state and national prevention programs. We utilized data collected by the New Mexico Violent Death Reporting System in its first 2 years of operation (2005 and 2006) in order to define the demographic patterns of adult suicides in the state and characterize risk factors. A total of 526 suicides occurred among adults during this time, with the majority being male (78.5%) and White non‐Hispanic (56.7%). The highest incidence was in adults between 45 and 54 years (28.1%). Firearms were the most commonly used mechanism, and “current depressed mood” the most commonly identified risk factor. High rates of adult suicide indicate the need for targeted prevention programs.     

侦查羁押制度:问题与出路——从查证保障功能角度分析

研究侦查羁押查证保障功能的意义在于检讨现行的侦查羁押期限配置是否合理.基于调研和对已有文献资料的分析发现:侦查羁押阶段虽有一定的查证保障功能,但与刑拘前阶段相比并无明显优势;尤须指出,逮捕阶段查证保障功能如此微弱,却配置了长达2月之久的期限,而查证保障功能较强的刑拘阶段仅配置了10天期限,致使两种期限的配置产生轻重倒置.基于平衡查证保障与权利保障双重需要的角度,有微调方案、中调方案和大调方案可供选择.以1996年刑事诉讼法传统为基础确定的中调方案较具可行性.无论哪种方案,均应进行取保候审和国家赔偿制度的同步改革.     

Data for 15 autosomal STR markers (Powerplex 16 System) from two Tunisian populations: Kesra (Berber) and Zriba (Arab)

Allele frequencies, together with some parameters of forensic interest, for 15 STRs included in the Powerplex 16 System (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, TH01, TPO and VWA) were estimated from two samples of unrelated individuals from Tunisia, of different ethnicity: Kesra (Berber) and Zriba (Arab). No deviations from Hardy-Weinberg equilibrium were observed after Bonferroni's correction for the number of loci analysed. Comparative analyses between our population data and other North African databases showed that significant differences were concentrated on loci with lowest values of diversity (mainly CSF1PO and D13S317), irrespective of ethnicity and geographic location.     

The recovery of semen from bathwater using the Evidence Recovery System (ERS)

Sexual offences are under-reported and ascertaining accurate offence numbers is difficult. Any methods which could increase the ability to obtain biological evidence or reduce the additional distress associated with reporting a sexual offence may result in an increase in reporting this crime type. The Evidence Recovery System (ERS) is designed to collect trace evidence, including hairs, fibres and biological evidence, from bath or shower water in a non-invasive manner. Initially, samples of semen were placed in baths filled with water, and washing was simulated using a range of body wash products. The water was then drained through the ERS before its filters were subjected to acid phosphatase testing and haematoxylin and eosin staining of spermatozoa. Recovered spermatozoa were then graded accordingly. Following this, the experiment was repeated with the addition of dirt/dust particulates during the washing stage, to simulate recovery of biological evidence in a more realistic environment. The results showed that spermatozoa considered ‘easy to find’ could regularly be obtained from bathwater using the ERS. It appeared that this recovery was not affected by the presence of different body wash products. When dust/dirt particles were added, the number of spermatozoa recovered increased at two of the evidence collection stages. The difference in recovery was considered to be statistically significant. This study provides evidence to suggest the feasibility of use of the ERS as a method to collect semen evidence from individuals subjected to sexual offences. The recovery of spermatozoa does not appear to be affected by the presence of a body wash, but does appear to be improved when skin cells, hair and other debris are transferred into the water, as would be likely during a bath/shower. Further to this, the possibility of obtaining spermatozoa from the home bath or shower of a victim following a post-offence bathing experience is implied.     

Strength of Evidence,Extraevidentiary Influence,and the Liberation Hypothesis: Data from the Field

To examine relationships between strength of evidence (SOE) and extraevidentiary variables in the context of Kalven and Zeisel’s (The American Jury, 1966) liberation hypothesis, post-trial questionnaire data were collected from judges, attorneys, and jurors associated with 179 criminal jury trials. SOE ratings were strongly correlated with jury verdicts on the three most serious charges against the defendant, and several extraevidentiary variables (i.e., pretrial publicity, trial complexity, charge severity, and foreperson demographics) were moderately correlated with verdicts. Extraevidentiary-verdict relationships remained significant when SOE was controlled, although extraevidentiary variables yielded only modest improvement in classification accuracy beyond SOE. In partial support of the liberation hypothesis, several case-related extraevidentiary variables were significantly related to jury verdicts only when the prosecution’s evidence was rated as moderately strong.     

Racial Threat,Social (Dis)organization,and the Ecology of Police: Towards a Macro-level Understanding of Police Use-of-force in Communities of Color

Abstract

In this paper, we examine use-of-force incidents as neighborhood processes to understand how rates and levels of use-of-force vary across New York City. We suggest that there are two distinct outcomes of force by the police: number of use-of-force incidents and level of force. Applying theories of racial threat, social disorganization, and Klinger’s ecological theory of policing, we conceptualize use-of-force as a neighborhood phenomenon rather than individual events. Our results suggest that rates and levels of force operate in some distinct ways. In particular, while we find that use-of-force is concentrated in Black neighborhoods, and is also more severe in Black neighborhoods, neighborhoods with higher racial and ethnic heterogeneity have decreasing force incidents, but with increasing severity. This may reflect different types of policing, with high rates of low-level police harassment occurring in primarily poorer, Black neighborhoods, and more isolated but severe incidents occurring in middle-income and wealthier mixed neighborhoods.     

Data for Y-chromosome haplotypes in Fang and Bubi populations from Bioko (Equatorial Guinea)

Haplotype frequencies for 16 Y-chromosomal short tandem repeat (DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635, DYS392, Y GATA H4, DYS437, DYS438 and DYS448) loci, included in the AmpFLSTR Yfiler PCR Amplification Kit, were analysed in 110 Fang and 133 Bubi individuals from Bioko Island, Equatorial Guinea. The diversity was higher in Fang population, probably since they were originally from the mainland, with which they maintain tribal village and family links, and to which they travel frequently. Comparisons were made with previously published haplotype data on European and African populations, and significant differences were found between them.     

A Comparative Criminological Study of Crime in Moscow (1923 and 1968-69)

In the spring of 1923, a criminological study of crime in Moscow was undertaken on the initiative of the Administrative Department of the Moscow Soviet of Working People's Deputies by law students of the School of Social Sciences of Moscow University No. 1. A collection of articles, The Criminal World of Moscow [Prestupnyi mir Moskvy], edited by Professor M. Gernet and published in 1924, was based upon it.     

Networking and Knowledge Transfer Between Research and Industry in Transition Countries: Empirical Evidence from the Slovenian Innovation System

Using empirical data from an innovation survey carried out in the Republic of Slovenia in 1997/1998, the paper analyses the innovation-relevant co-operation pattern between different kinds of research institutes and industry. The hypothesis is made that system transformation is not yet accomplished in Slovenia, and that the innovation system is still fragmented. While there is intense co-operation between Slovenian research institutes and companies, the level of co-operation between university institutes and industrial firms remains below the average of all Slovenian research institutes, although one focal point in the co-operation activities of university institutes is the support of firms in market introduction. Mainly larger institutes co-operate with larger firms, whereas small institutes hardly co-operate. Consequently, the challenge of innovation policy is to integrate all participants of the Slovenian innovation system in a structure of mutual knowledge and information exchange.     

农民工养老保险参保行为及其影响因素分析——基于江苏五市(县)的调查数据

本研究基于江苏五市(县)调查数据,反映了农民工养老保险参保状况与模式,并对影响农民工参保的个体特征、外出打工原因、收入、流动性、制度、留城意愿六个方面的因素给出了解释.调查结果表明,当前农民工养老保险参保率低的问题主要是由制度障碍造成的,包括缴费年限太长、养老关系接续转移困难;个体特征中的性别和年龄影响比较显著,文化程度的影响相对较低;城市之间的流动性对参保行为的显著影响,说明养老关系接续转移存在的困难和农民工对养老保险制度的信任度不高.在进城之前,农民工的个体特征已基本成型,流动性强也是客观事实,因此,要提高农民工养老保险的参保率,须从破除制度障碍入手.
