This paper uses data from an ongoing panel study of urban youth to examine the causes and correlates of hidden gun carrying among young urban males. The analysis assesses the changing impact of gang membership, drug sales, and peer gun ownership for protection on gun carrying at nine separate points over the early adolescent to young adult life course. In early adolescence, gang membership is a strong motivation for gun carrying. At somewhat older ages, drug dealing, particularly high drug sales, and illegal peer gun ownership replace gang membership as the primary determinants of illegal gun carrying. 相似文献

Empirical models of spatial voting allow us to infer legislators' locations in an abstract policy or ideological space using their roll‐call votes. Over the past 25 years, these models have provided new insights about the U.S. Congress, and legislative behavior more generally. There are now a number of alternative models, estimators, and software packages that researchers can use to recover latent issue or ideological spaces from voting data. These different tools usually produce substantively similar estimates, but important differences also arise. We investigated the sources of observed differences between two leading methods, NOMINATE and IDEAL. Using data from the 1994 to 1997 Supreme Court and the 109th Senate, we determined that while some observed differences in the estimates produced by each model stem from fundamental differences in the models' underlying behavioral assumptions, others arise from arbitrary differences in implementation. Our Monte Carlo experiments revealed that neither model has a clear advantage over the other in the recovery of legislator locations or roll‐call midpoints in either large or small legislatures. 相似文献

This article will focus on the evolution of the collaborative work of the Louisiana Rural Trauma Services Center (LRTSC), a Center within the National Child Traumatic Stress Network, and the 23rd Judicial District, a jurisdiction in south Louisiana serving three rural parishes. We will describe how the collaboration and joint efforts, and the changes that have been made in terms of availability of evaluation and treatment resources, seem to be influencing both the educational and judicial systems in St. James Parish and potential sustainability of some of the identified resources. The article will examine how the court and the LRTSC work together with emphasis on the evaluation, reporting and recommendation processes, outcomes and benefits to date, and challenges for the future. 相似文献
