PROFILING AND POLICE LEGITIMACY: PROCEDURAL JUSTICE,ATTRIBUTIONS OF MOTIVE,AND ACCEPTANCE OF POLICE AUTHORITY*

This paper reports the results of four studies that investigate racial profiling as an attribution about police motives. Each study explores, first, the types of police behavior that heighten or lessen the occurrence of profiling attributions and, second, the consequences of such attributions. Results support prior studies in finding that judgments about whether the police are profiling are associated with the level of public support for the police. The studies then extend the analysis of subjective profiling judgments by examining their antecedents. The findings support the procedural justice hypothesis that the fairness with which the police exercise their authority influences whether members of the public view the police as profiling.     

MOTHERING,FATHERING, AND DIVORCE: THE INFLUENCE OF DIVORCE ON REPORTS OF AND DESIRES FOR MATERNAL AND PATERNAL INVOLVEMENT*

The present study investigated the extent to which young adults' reports of—and desires for—maternal and paternal involvement differed between intact and divorced families. An ethnically diverse sample of 1,376 young adults completed measures of reported and desired mothering and fathering across 20 parenting domains. Results indicated that both reports of and desires for father involvement differed sharply by family form (intact versus divorced), whereas few family form differences emerged for reported or desired mother involvement. These findings are discussed in terms of implications for custody and access decisions within the family court system.     

THE INTERACTION OF RACE, GENDER, AND AGE IN CRIMINAL SENTENCING: THE PUNISHMENT COST OF BEING YOUNG, BLACK, AND MALE

Prior theory and research on sentencing oversimplify the role of race, gender and age in judicial decision making. In this article we present a "focal concerns" theory of judicial decision making to frame hypotheses regarding the effects on sentencing of these social statuses, both singly and in combination. Analyzing statewide sentencing outcomes in Pennsylvania for 1989–1992, we find that, net of controls: (1) young black males are sentenced more harshly than any other group, (2) race is most influential in the sentencing of younger rather than older males, (3) the influence of offender's age on sentencing is greater among males than females, and (4) the main effects of race, gender, and age are more modest compared to the very large differences in sentencing outcomes across certain age-race-gender combinations. These findings demonstrate the importance of considering the joint effects of race, gender, and age on sentencing, and of using interactive rather than additive models.     

DEALERS,THIEVES, AND THE COMMON DETERMINANTS OF DRUG AND NONDRUG ILLEGAL EARNINGS*

Drug crime often is viewed as distinctive from other types of crime, meriting greater or lesser punishment. In view of this special status, this article asks whether and how illegal earnings attainment differs between drug sales and other forms of economic crime. We estimate monthly illegal earnings with fixed‐effects models, based on data from the National Supported Work Demonstration Project and the National Longitudinal Survey of Youth. Although drug sales clearly differ from other types of income‐generating crime, we find few differences in their determinants. For example, the use of cocaine or heroin increases illegal earnings from both drug and nondrug crimes, indicating some degree of fungibility in the sources of illegal income. More generally, the same set of factors—particularly legal and illegal opportunities and embeddedness in criminal and conventional networks—predicts both drug earnings and nondrug illegal earnings.     

THE EFFECTS OF DIVORCE AND CUSTODY ARRANGEMENTS ON CHILDREN'S BEHAVIOR, DEVELOPMENT, AND ADJUSTMENT

This article summarizes the consensus among a group of experts from developmental and clinical psychology, sociology, social welfare, and law who sought to evaluate existing empirical evidence regarding the ways in which children are affected by divorce and the varying custody arrangements that follow it. Divorce and/or single parenthood tend to have adverse effects on children's adjustment, with the magnitude of the effects varying depending on the psychological status of the two parents, the extent of conflict between them, and the financial circumstances, particularly after divorce. Children whose nonresidential parents continue to support them financially, those whose custodial parents are psychologically healthy, and those who have and maintain meaningful relationships with nonresidential parents tend to be affected less by the divorce, especially when there is no conflict between the parents. Interventions should thus be designed with these factors in mind.     

INTERROGATING RACE,CRIME, AND JUSTICE IN A TIME OF UNEASE AND RACIAL TENSION

This address has a twofold purpose. First, as the first African American to serve as president of the American Society of Criminology (ASC), I celebrate the contributions of scholars of color to the study of crime and criminal justice and to the ASC. I do so by pointing out the accomplishments of several African American scholars whose contributions are numerous and exemplary. I also emphasize that African Americans are joined in their efforts by scholars of multiple other colors, including, Latinos/as, Native Americans, and Asians. Second, in view of responses to apparent unrest and racial tension in U.S. society that is signaled by lethal violence between police and U.S. residents of color, I offer four recommendations regarding how we might proceed with our research, and report our findings, in ways that improve the likelihood of helping to inform societal debates and policy developments around crime and justice issues. In my conclusion, I encourage the ASC to 1) continue to grow the diversity of its membership and to integrate the research and findings of scholars of color into the mainstream of criminology; and 2) take further steps to conduct research and share findings with diverse audiences to ensure that post‐truth does not become normative regarding crime and justice issues.     

RACE,CODE OF THE STREET,AND VIOLENT DELINQUENCY: A MULTILEVEL INVESTIGATION OF NEIGHBORHOOD STREET CULTURE AND INDIVIDUAL NORMS OF VIOLENCE*

The study outlined in this article drew on Elijah Anderson's (1999) code of the street perspective to examine the impact of neighborhood street culture on violent delinquency. Using data from more than 700 African American adolescents, we examined 1) whether neighborhood street culture predicts adolescent violence above and beyond an adolescent's own street code values and 2) whether neighborhood street culture moderates individual-level street code values on adolescent violence. Consistent with Anderson's hypotheses, neighborhood street culture significantly predicts violent delinquency independent of individual-level street code effects. Additionally, neighborhood street culture moderates individual-level street code values on violence in neighborhoods where the street culture is widespread. In particular, the effect of street code values on violence is enhanced in neighborhoods where the street culture is endorsed widely.     

FEAR,TV NEWS,AND THE REALITY OF CRIME*

Data from a 1997 survey of 2, 250 Florida residents are used to assess whether and how the reality of crime influences the relationship between watching TV news and fear of crime. Local crime rates, victim experience, and perceived realism of crime news operationalize the reality of crime and are included in ordinary least squares (OLS) estimates of the TV news and fear of crime relationship. These measures of reality are also used as contexts for disaggregating the analysis. Local and national news are related to fear of crime independent of the effects of the reality of crime and other controls. Local news effects are stronger, especially for people who live in high crime places or have recent victim experience. This contextual pattern of findings is consistent with a conclusion that TV news is most influential when it resonates the experience or crime reality of respondents.     

CONCEPTUALIZING VISITATION RESISTANCE AND REFUSAL IN THE CONTEXT OF PARENTAL CONFLICT,SEPARATION, AND DIVORCE

A child's visitation resistance and refusal (VRR) in the context of parental separation, divorce, and post‐divorce litigation must not prematurely be interpreted as evidence of alienation, a conclusion which can be as detrimental to the family system as it is ill founded. The present article proposes a child‐centered, developmentally informed heuristic with which forensic evaluators might begin to more uniformly approach the potential causes of and remedies for VRR. An attachment‐based, step‐wise decision tree is described together with an overview of the remedies presently believed most appropriate to each. Recommendations for empirical study of the multiple convergent dynamics which determine VRR and establishment of corresponding interventions follow.     

IMAGES OF DANGER AND CULPABILITY: RACIAL STEREOTYPING,CASE PROCESSING,AND CRIMINAL SENTENCING*

In this paper we argue that the meaning of race in criminal justice decision making will vary depending on other offender and offense characteristics, and that differences in treatment within races may therefore be as large as differences between races. We find that, among adult drug offenders from Washington State, those white offenders who most closely resemble the stereotype of a dangerous drug offender receive significantly harsher treatment than other white offending groups, while among black offenders, it is the defendants who least resemble a dangerous drug offender who receive substantially different—in this case, less punitive—treatment than other black offenders. That is, the exceptions are made for the most serious and the least serious offenders. We discuss the implications of these findings.     

CLASS,GENDER, AND ARREST: AN INTERGENERATIONAL ANALYSIS OF WORKPLACE POWER AND CONTROL*

Power‐control theory posits that parental workplace positions affect adolescent law violation. To date, however, no test of the theory has directly measured occupational power and control. This paper tests whether parental and adolescent workplace freedom and control affect criminal behavior and arrest as the theory predicts, using data from a prospective longitudinal survey of 1, 000 adolescents and their parents. The results suggest sex differentials in the effects of maternal authority position and parental freedom and control. In particular, daughters whose mothers hold authority positions are more likely to be arrested than are daughters whose mothers do not hold such positions. The effects of adolescent employment also differ by sex, with perceived workplace power and control reducing rates of arrest among females but increasing them among males.     

STRESS,GENES, AND GENERALIZABILITY ACROSS GENDER: EFFECTS OF MAOA AND STRESS SENSITIVITY ON CRIME AND DELINQUENCY*

In the current study, we extend the gene‐by‐environment interaction (cGxE) literature by examining how a widely studied polymorphism, the MAOA upstream variable number tandem repeat (MAOA‐uVNTR) interacts with distal and proximal stressors to explain variation in crime and delinquency. Prior research findings have revealed that MAOA‐uVNTR interacts with single indicators of environmental adversity to explain criminal behavior in general‐population and incarcerated samples. Nevertheless, the genetically moderated stress sensitivity hypothesis suggests that increased risk for criminal behavior associated with variation in the MAOA‐uVNTR can be best understood in the context of both distal stress during childhood and proximal stress in adulthood. Therefore, we employed Tobit regression analyses to examine a gene–distal–proximal environment (CGxExE) interaction across gender in a sample of university students (n = 267) and with data from the National Longitudinal Study of Adolescent to Adult Health (Add Health; n = 1,294). The results across both sets of analyses demonstrate that variation in the MAOA‐uVNTR interacts with distal and proximal stress to lead to increased risk for criminal behavior in males. Although proximal life stress is associated with an increase in crime and delinquency, this effect is more pronounced among MAOA‐L allele carriers that have experienced distal stress.     

RACE,RACIAL THREAT,AND SENTENCING OF HABITUAL OFFENDERS*

As legislatures proliferate novel “enhancements” to criminal sentencing, such as “three-strikes” and related provisions, and as criminologists debate their effects, the role of existing enhancements, such as habitual offender statutes, has received little empirical attention. This article explores the effect of race in the decision to prosecute and sentence eligible defendants as “habitual” offenders. During FY 1992–93, 9,690 males admitted to prison in Florida were statutorily eligible (two prior felony convictions or one prior violent felony conviction) for sentencing as “habitual” offenders. Approximately 20% received that disposition. They will serve at least 75% of their enhanced sentence as compared with the state average of about 40%. Logistic regression, controlling for prior record, crime seriousness, and other relevant factors, shows a significant and substantial race effect. The disadvantage of black defendants is particularly strong for drug offenses and for property crimes that have relatively high victimization rates for whites (larceny, burglary). Race is less consequential for violent and weapons-related crimes. Race effects are more often significant in sentencing contexts that are low in terms of percent black, racial income inequality, drug arrest rates, and violent crime rates. The relevance of these findings for a “racial threat” interpretation of sentencing outcomes is discussed.

MERGERS, STANDARD OF PROOF AND EXPERT ECONOMIC EVIDENCE

There is an increasing use of complex econometric modellingin EC merger control proceedings. The question is whether econometricsare subject to a standard of evidence similar to that applicableto facts and theories that the Commission traditionally usesand articulates in its merger decisions or whether there shouldbe some margin of discretion left to the Commission in the treatmentand handling of econometric evidence. In the former case, ECcourts would exert an intensive review of the Commission's useand articulation of econometric evidence. In the latter case,EC courts would adopt a rather deferential approach. While theissue has not yet been dealt with before EC courts, this articlesubmits that the Commission should use econometrics with cautionand, hence, should meet a relatively high evidentiary thresholdbefore admitting the results of econometric models into evidence.Several guiding principles of evidence are suggested, whichare not intended to negate the Commission's margin of discretion,but would, nevertheless, ensure that econometrics be subjectto a fairly high standard of proof.
