Case-control studies: Design issues for criminological applications

The current understanding of the determinants of homicide derives primarily from studies in which data are aggregated for geopolitical units. Case-control studies and other analytic methods are needed to test causal hypotheses regarding the risk of homicide victimization or perpetration for individuals. Strengths and limitations of the case-control method are illustrated by comparing the design with cohort studies. Fundamental issues include the selection and comparability of cases and controls, effects of biases, interpretation of risk estimates, and problems of implementation. Increased use of this method should advance our understanding of homicide and other forms of intentional violence.Presented in part at the 37th Annual Meeting of the American Society of Criminology, San Diego, California, November 16, 1985.     

Stress-related temporary hearing loss--evaluation of bio-humoral parameters: forensic and criminological applications

The body-alarm reaction results from the activation of hypothalamic-pituitary-adrenal axis, which can lead to physio-psychological phenomena such as an exclusion/occlusion of the sense of hearing. One hypothesis to explain this alteration consists in a hydromechanical dysfunction of the internal ear attributable to antidiuretic hormone. In this study, we evaluated the perception of acoustic stimuli administered in stressful conditions in 14 phobic patients and in 20 healthy subjects, in order to assess the influence of stress on perceiving capabilities. We also measured the concentration of salivary cortisol and IL-1β and neurovegetative parameters to objectivise and quantify the physiological reactions. Our results show a worse perception of the frequencies of the human voice under stress; these findings could have a dual value: in the legal field, concerning criminal liability, and on the operative context, regarding the efficiency of verbal communication among law enforcement officers in situations inducing intense emotional stress.     

The criminological potential of pure sociology

The pure sociology perspective invented by Donald Black, a general theoretical framework for the prediction and explanation of social reality, has considerable potential for the scientific understanding of criminal behavior. Several scholars have profitably drawn upon Black’s proposal that a significant amount of crime is a form of disputing or social control, especially to explain violent conflict. However, pure sociology has not yet been extended and applied to criminal behavior more broadly. A pure sociology of predatory behavior, for instance, would address the location and direction in social space of predators, prey, and third parties. In expanding criminological thought, however, pure sociology also challenges it. Pure sociology explanations are not restricted by time or place, a feature not easily realized with a concept so closely tied to a relatively recent social invention: the state. Additionally, the supra-psychological, -anthropocentric, and -teleological nature of pure sociology generates explanations of behavior that are at odds with many of the assumptions of traditional criminology. Ultimately, then, pure sociology yields a new paradigm for the explanation of behavior the state defines as criminal. Presented at the annual meeting of the American Society of Criminology.

Interaction of criminological research and public policy

We examine here some of the interactions of research and policy over the past several decades. The “rehabilitation period” was effectively terminated by nulleffect evaluations of various rehabilitation techniques. The “just deserts-utilitarian period” was fed by research estimates of the deterrent and incapacitative effects of criminal justice activities. The more recent “overt politicization period” saw the earlier attempt to bring rational and theory-based perspectives to policy development replaced by much stronger emphasis on political concerns. We explore possible ways to reestablish the research-policy connections.

The historical roots and development of criminological statistics

The history of the development of criminological statistics must examine the emergence of social statistics in general. The theoretical concerns and technical questions raised by early criminologists cannot be isolated from the wider concerns of sociologists and statisticians at work in other fields. This article traces the history and problems of crime and justice statistics through the distinct periods: a “preparatory” phase (1650–1800),and a “conceptualization” phase (1800–1914). In addition, while specifically noting a dependent relationship with the fields of demography and statistics, the separation of criminological statistics as an automous area is considered. The use of criminal justice statistics for comparative and other purposes has come under considerable review and criticism during recent years, and an examination of historical sources and problems serves to increase the understanding and usefulness of these statistics today.     

Systemic error: measuring gender in criminological research

This study examines how sex and gender are measured and operationalized in studies on criminology and criminal justice (CCJ) through content analysis of peer-reviewed journals. Despite that they are distinct and not always parallel, the terms sex and gender are often used interchangeably in CCJ research. Moreover, despite increasing recognition that gender-responsive practices are important at every stage of the criminal justice process, gender is almost exclusively measured as a male-female binary, miscategorizing and failing to properly account for those who do not fit in one of those gender identities. There are important implications for the safety of such individuals, as both victims and offenders throughout the criminal justice process, therefore it is essential that we more accurately measure gender in this field. Recommendations for improvement are addressed.     

Kicking to death - forensic and criminological aspects.

A total of 36,274 forensic autopsies was performed in Berlin, between 1980 and 1987, including 152 cases (0.42%) in which death had been caused by blunt violence due to kicking. Data were collected on both victims and offenders, postmortem findings, causes of death and the way violence had been perpetrated. The greater part of victims and offenders had been males originating from lower social strata. Most of the victims and offenders had been in relationship with each other prior to the offence. Typical course of events: Victims and offenders, under influence of alcohol, became involved in a brawl, usually for trivial reasons, which soon led to physical fighting. When the victim had been knocked to the ground, the offender started forceful kicking. Bleeding to death and head injury were frequent causes of death. More than 50% of all offences were committed by single offenders. The diagnosis of kicking to death can at best be derived from presence of boot traces leaving shaped injuries. The trace-generating boot can be identified as offending tool by means of comparative police investigation. In addition to evaluation of shoe sole profiles, there is other trace-relevant material that may be sampled from a suspected offender's footwear (skin cells, hair, blood, body tissue) and used to identify findings by DNA analysis. There may be injuries with visible patterns supporting suspicion of kicking and trampling, although conclusive confirmation can be obtained only by testimony by a witness or confession by the offender.     

Epidemiological characteristics of male sexual assault in a criminological database

Sexual assault among males, compared with females, is understudied, and may also be significantly underreported. Past studies have relied primarily on population-based survey data to estimate the prevalence of sexual assault and associated health outcomes. However, survey-based studies rely primarily on self-reports of victimization and may not accurately estimate the true prevalence of male sexual assault victimization. In order to obtain a detailed assessment of sexual assault among males, criminological databases like the National Incident Based Reporting System (NIBRS) may provide an important and unique source of information. The objective of the current study was to use data from the 2001-2005 NIBRS to construct an epidemiological profile of sexual assault among males. Our results suggest that the incidence of sexual assault was higher among young males (less than 19 years of age), with approximately 90% of all cases being reported among members of this age group. Among males of all ages, forcible fondling and sodomy were the most prevalent forms of sexual assault. Results from additional analyses include age- and race-specific rates of male sexual assault, the prevalence and severity of injury, and time trends detailing incidence by time of the day and location of the incident. Our analyses show that sexual assault is experienced by males of all age groups. However, the rate of sexual assault is higher among younger males. Despite some limitations, results from this study suggest that NIBRS data may provide a important complement to survey data for understanding breadth and consequences of male sexual assault.     

A note on quetelet and the development of criminological statistics

This Note clarifies several ambiguities in the claims that Salas and Surette (1984) have made about the Belgian criminologist Adolphe Quetelet. Specifically, it suggests that Quetelet (1) never articulated a concept of political relations or of the political state; (2) consistently rejected the need for ‘theoretical’ interpretation of empirical ‘data,’ (3) borrowed the notion of ‘statistique morale’ from French and German moral statisticians, and (4) vacillated between the poles of determinism and free-will philosophy.

On the consequences of ignoring genetic influences in criminological research

Purpose

Many criminological scholars explore the social causes of crime while giving little consideration to the possibility that genetic factors underlie the observed associations. Indeed, the standard social science method (SSSM) assumes genetic influences do not confound the association between X and Y. Yet, a nascent stream of evidence has questioned the validity of this approach by revealing many criminological variables are at least partially affected by genetic influences. As a result, a substantial proportion of the literature may be misspecified due to uncontrolled genetic factors. No effort has been made to directly estimate the extent to which genetic confounding has biased the associations presented in criminological studies.

Methods

The present study seeks to address this issue by drawing on simulated datasets.

Results/Conclusions

Results suggest genetic confounding may account for a negligible portion of the relationship between X and Y when their correlation (r_yx) is larger than the correlation between genetic factors and Y (i.e., r_yx > r_yg). Genetic confounding appears to be much more problematic when the correlation between X and Y is in the moderate-to-small range (e.g., r_yx = .20) and the genetic effect is in the moderate-to-large range (e.g., r_yg ≥ .30).     

Rap sheets in criminological research: Considerations and caveats

The types of errors found in official criminal history records are not completely understood by many researchers, and this lack of understanding can lead to serious misinterpretations. Analyses of a recently developed database of New Orleans offenders indicate that the use of rap sheets with a limited catchment area can lead to gross distortions of the effects of variables related to geographic mobility, such as race and age. Evidence from a number of sources indicates that false-negative error is a serious problem, particularly in fingerprint-based record systems. In addition, arrest records lend themselves to a variety of common misinterpretations by researchers in the coding process, including failing to identify multievent arrests, misclassifying arrests, and treating arrest or custody process events as crimes indicating criminal activity of the individual while free. Solutions to some of these problems are suggested.
