Puzzling It Out: The Current State of Scientific Knowledge on Pre-Kindergarten Effects - A Consensus Statement

Scientific research has established that if all children are to achieve their developmental potential, it is important to lay the foundation during the earliest years for lifelong health, learning, and positive behavior. A central question is how well our public pre-kindergarten (pre-K) programs are doing to build this foundation.Forty-two states and the District of Columbia, through 57 pre-K programs, have introduced substantial innovations in their early education systems by developing the infrastructure, program sites, and workforce required to accommodate pre-K education. These programs now serve nearly 30 percent of the nation's 4-year-olds and 5 percent of 3-year-olds

The Effectiveness of the Sheriff\u27s Department\u27s Juvenile Diversion Projects in Southeast Los Angeles County (CA)

The major message of this report is that juvenile diversion, as practiced by the three Sheriff\u27s Department Projects in southeast Los Angeles County, appears to be quite successful. The accomplishments of these three projects were assessed with regard to two primary goals: 1. Reduction of the number of juveniles referred further into the juvenile justice system (probation and the courts) by law enforcement. 2. Reduction of the incidence of juvenile delinquency among youthful offenders subsequent to diversion. 1. The pattern of findings reviewed in this report provide convincing evidence that both these goals are being met. The highlights of that evidence are as follows: a. With the inception of the diversion projects in 1976, the number of diversions from the participating law enforcement stations increased substantially. b. The majority of the juveniles selected for diversion would probably have been referred to the Probation Department on non-detained petition applications if diversion had not been available; only a minority would have been counseled and released. c. The records of the sheriff\u27s stations participating in the diversion projects showed that they sent fewer non-detained petition applications to the Probation Department after the projects began operations

Formal System Processing of Juveniles: Effects on Delinquency

Justice practitioners have tremendous discretion on how to handle juvenile offenders. Police officers, district attorneys, juvenile court intake officers, juvenile and family court judges, and other officials can decide whether the juvenile should be “officially processed” by the juvenile justice system, diverted from the system to a program, counseling or some other services, or to do nothing at all (release the juvenile altogether). An important policy question is which strategy leads to the best outcomes for juveniles. This is an important question in the United States, but many other nations are concerned with the decision to formally process or divert juvenile offenders. There have been a number of randomized experiments in the juvenile courts that have examined the impact of juvenile system processing that should be gathered together in a systematic fashion to provide rigorous evidence about the impact of this decision on subsequent offending by juveniles. Our objective is to answer the question: Does juvenile system processing reduce subsequent delinquency? Based on the evidence presented in this report, juvenile system processing appears to not have a crime control effect, and across all measures appears to increase delinquency. This was true across measures of prevalence, incidence, severity, and self-report. Given the additional financial costs associated with system processing (especially when compared to doing nothing) and the lack of evidence for any public safety benefit, jurisdictions should review their policies regarding the handling of juveniles

The Association of Cognitive Ability with Right-wing Ideological Attitudes and Prejudice: A Meta-analytic Review

The cognitive functioning of individuals with stronger endorsement of right-wing and prejudiced attitudes has elicited much scholarly interest. Whereas many studies investigated cognitive styles, less attention has been directed towards cognitive ability. Studies investigating the latter topic generally reveal lower cognitive ability to be associated with stronger endorsement of right-wing ideological attitudes and greater prejudice. However, this relationship has remained widely unrecognized in literature. The present meta-analyses revealed an average effect size of r =-.20 [95% confidence interval (95% CI) [-0.23, -0.17]; based on 67 studies, N=84 017] for the relationship between cognitive ability and right-wing ideological attitudes and an average effect size of r=-.19 (95% CI [-0.23, -0.16]; based on 23 studies, N=27 011) for the relationship between cognitive ability and prejudice. Effect sizes did not vary significantly across different cognitive abilities and sample characteristics. The effect strongly depended on the measure used for ideological attitudes and prejudice, with the strongest effect sizes for authoritarianism and ethnocentrism. We conclude that cognitive ability is an important factor in the genesis of ideological attitudes and prejudice and thus should become more central in theorizing and model building

On the Interplay between Consumer Dispositions and Perceived Brand Globalness: Alternative Theoretical Perspectives and Empirical Assessment

Although prior research is congested with constructs intended to capture consumers’ dispositions toward globalization and global/local products, their effects appear to replicate with difficulty, and little is known about the underlying theoretical mechanisms. This investigation revisits the relationship between prominent consumer dispositions (consumer ethnocentrism, cosmopolitanism, global/local identity, globalization attitude) and perceived brand globalness as determinants of consumer responses to global brands. Drawing on selective perception and social identity theories, the authors consider several theory-based model specifications that reflect alternative mechanisms through which key consumer dispositions relate to brand globalness and affect important brand-related outcomes. By employing a flexible model that simultaneously accounts for moderating, mediating, conditional, and direct effects, we empirically test these rival model specifications. A meta-analysis of 264 effect sizes obtained from 13 studies with 23 unique data sets and a total sample of 1,410 consumers raises concerns regarding the (potentially overstated) utility of consumer dispositions for explaining consumer responses to global brands. It also reveals a need for further conceptual contemplation of their function in international consumer research and managerial practice

The effects of problem-oriented policing on crime and disorder

Problem-oriented Policing (POP) was first introduced by Herman Goldstein in 1979. The approach was one of a series of responses to a crisis in effectiveness and legitimacy in policing that emerged in the 1970s and 1980s. Goldstein argued that police were not being effective in preventing and controlling crime because they had become too focused on the “means” of policing and had neglected the “goals” of preventing and controlling crime and other community problems. Goldstein argued that the unit of analysis in policing must become the “problem” rather than calls or crime incidents as was the case during that period. POP has had tremendous impact on American policing, and is now one of the most widely implemented policing strategies in the US. To synthesize the extant problem-oriented policing evaluation literature and assess the effects of problem-oriented policing on crime and disorder Eligible studies had to meet three criteria: (1) the SARA model was used for a problemoriented policing intervention; (2) a comparison group was included; (3) at least one crime or disorder outcome was reported with sufficient data to generate an effect size. The unit of analysis could be people or places. Several strategies were used to perform an exhaustive search for literature fitting the eligibility criteria. First, a keyword search was performed on an array of online abstract databases. Second, we reviewed the bibliographies of past reviews of problem-oriented policing. Third, we performed forward searches for works that have cited seminal problem-oriented policing studies. Fourth, we performed hand searches of leading journals in the field. Fifth, we searched the publications of several research and professional agencies. Sixth, after finishing the above searches we e-mailed the list of studies meeting our eligibility criteria to leading policing scholars knowledgeable in the area of problem-oriented policing to ensure we had not missed any relevant studies. For our ten eligible studies, we provide both a narrative review of effectiveness and a meta-analysis. For the meta-analysis, we coded all primary outcomes of the eligible studies and we report the mean effect size (for studies with more than one primary outcome, we averaged effects to create a mean), the largest effect, and the smallest effect. Because of the heterogeneity of our studies, we used a random effects model. Based on our meta-analysis, overall problem-oriented policing has a modest but statistically significant impact on reducing crime and disorder. Our results are consistent when examining both experimental and quasi-experimental studies. Conclusions: We conclude that problem-oriented policing is effective in reducing crime and disorder, although the effect is fairly modest. We urge caution in interpreting these results because of the small number of methodologically rigorous studies on POP and the diversity of problems and responses used in our eligible studies

Scared Straight and Other Juvenile Awareness Programs for Preventing Juvenile Delinquency: A Systematic Review

Programs like ‘Scared Straight’ involve organized visits to prison facilities by juvenile delinquents or children at risk for becoming delinquent. The programs are designed to deter participants from future offending by providing first-hand observations of prison life and interaction with adult inmates. Results of this review indicate that not only does it fail to deter crime but it actually leads to more offending behavior. Government officials permitting this program need to adopt rigorous evaluation to ensure that they are not causing more harm to the very citizens they pledge to protect

HIV Risk Behavior Self-Report Reliability at Different Recall Periods

Few studies have investigated the optimal length of recall period for self-report of sex and drug-use behaviors. This meta-analysis of 28 studies examined the test-retest reliability of three commonly used recall periods: 1, 3, and 6 months. All three recall periods demonstrated acceptable test-retest reliability, with the exception of recall of needle sharing behaviors and 6-months recall of some sex behaviors. For most sex behaviors, a recall period of 3 months was found to produce the most reliable data; however, 6 months was best for recalling number of sex partners. Overall, shorter periods were found to be more reliable for recall of drug-use behaviors, though the most reliable length of recall period varied for different types of drugs. Implications of the findings and future directions for research are discussed

The Effectiveness of Incarceration-Based Drug Treatment on Criminal Behavior: A Systematic Review

Many, if not most, incarcerated offenders have substance abuse problems. Without effective treatment, these substance-abusing offenders are likely to persist in non-drug offending. The period of incarceration offers an opportunity to intervene in the cycle of drug abuse and crime. Although many types of incarceration-based drug treatment programs are available (e.g., therapeutic communities and group counseling), the effectiveness of these programs is unclear. The objective of this research synthesis is to systematically review quasi-experimental and experimental (RCT) evaluations of the effectiveness of incarceration-based drug treatment programs in reducing post-release recidivism and drug relapse. A secondary objective of this synthesis is to examine variation in effectiveness by programmatic, sample, and methodological features. In this update of the original 2006 review (see Mitchell, Wilson, and MacKenzie, 2006), studies made available since the original review were included in an effort to keep current with emerging research. This synthesis of evaluations of incarceration-based drug treatment programs found that such programs are modestly effective in reducing recidivism. These findings most strongly support the effectiveness of therapeutic communities, as these programs produced relatively consistent reductions in recidivism and drug use. Both counseling and incarceration-based narcotic maintenance programs had mixed effects. Counseling programs were associated with reductions in recidivism but not drug use; whereas, incarceration-based narcotic maintenance programs were associated with reductions in drug use but not recidivism. Note that our findings regarding the effectiveness of incarceration-based narcotic maintenance programs differ from a larger review of community-based narcotic maintenance programs (see Egli, Pina, Christensen, Aebi, and Killias, 2009). Finally, boot camp programs for drug offenders had negligible effects on both recidivism and drug use
