Using ARIMA models to predict prison populations

In this study a time-series model for predicting Louisiana's prison population was developed using the iterative Box-Jenkins modeling methodologyidentification, estimation, and diagnostic checking. The time-series forecasts were contrasted with results of regression models and an exponential smoothing model. The results indicate that the time-series model is the superior model as indicated by the usual measures of predictive accuracy. When compared with actual data the predictions appeared sufficiently adequate to meet the needs of the correctional system for short-term planning.     

Virtual determination of sex: metric and nonmetric traits of the adult pelvis from 3D computed tomography models

Examination of the adult os coxae and sacrum is one of the most common methods of sex estimation from bone. Medical imaging, such as computed tomography (CT), provides the opportunity for three-dimensional (3D) imaging of the skeleton from clinical scans of known individuals in situ. In this study, a randomly selected subset of abdominopelvic CT-derived models were used to evaluate simple, repeatable metric methods of sex estimation based on a combination of obstetric measurements and the traditionally nonmetric Phenice-derived traits. A four-variable discriminant function for sex estimation was developed based on statistical analyses. Overall, the cross-validated accuracy of this method was 100%, with inter-observer error showing an average of only 2.2%. Comparative analysis was run on the data set using FORDISC 3.0. This study shows that current sex determination standards from the pelvis should be updated to include more in vivo data to increase the accuracy of identification.     

The Crime Reduction Effects of Public CCTV Cameras: A Multi‐Method Spatial Approach

Public Closed Circuit TeleVision (CCTV) initiatives have been utilized as methods of monitoring public space for over two decades. Evaluations of these efforts to reduce crime have been mixed. Furthermore, there has been a paucity of rigorous evaluations of cameras located in the USA. In this analysis, crime in the viewshed of publicly funded CCTV cameras in Philadelphia, PA, is examined using two evaluation techniques: hierarchical linear modeling and weighted displacement quotients. An analysis that incorporates controls for long‐term trends and seasonality finds that the introduction of cameras is associated with a 13% reduction in crime. The evaluation suggests that while there appears to be a general benefit to the cameras, there were as many sites that showed no benefit of camera presence as there were locations with a positive outcome on crime. The policy implications of these findings are discussed.

School Vandalism in Mexico

Mexico, like other countries in Latin America, is currently facing significant problems with regard to juvenile antisocial behavior and crime. The current study explores some of the factors associated with school vandalism in public high schools. Multilevel modeling with survey data from 22,345 students from 249 schools, acquired over two years, was used to determine how much variation in the rates of school vandalism exists between and within schools, and to detect individual and contextual characteristics that explain significant proportions of the variance. Results demonstrated significant differences across schools in the rates of student vandalism, most of which were associated with gang involvement, drug use, bullying, no attachment to school rules, and unequal treatment of students by teachers. These results are discussed in relation to the literature on school vandalism, and implications for the prevention of school vandalism are discussed.     

A Growth Curve Analysis of the Joint Influences of Parenting Affect,Child Characteristics and Deviant Peers on Adolescent Illicit Drug Use

This study purports that parental rejection and warmth are critical to the development of adolescent drug use, and investigates a model that also considers children's vulnerability and deviant peer affiliations. It tests mediation through the proximal risk factor of deviant peers. Poisson growth curve modeling was used to examine participants from the Canadian National Longitudinal Survey of Children and Youth (NLSCY; N=2194) over 4 waves. Results indicated that parental rejection was positively related to drug use, whereas parental warmth was negatively related to it. Both effects were significant when child ADHD symptoms were taken into account. Parental rejection and warmth had differential effects over time. Deviant peer affiliations were positively associated with drug use, did not have a differential influence over time, and did not mediate the other effects. There was significant between-individual (level 2) variability in drug use. Results are discussed in light of adolescent perceptions of parent-child relationships.

Evidence for Social and Behavior Problems in Low-Income,Urban Preschoolers: Effects of Site,Classroom, and Teacher

Teacher ratings of 336 preschool children (mean age = 48 months) attending two urban Head Start programs were collected to examine the influence of contextual variables of teacher training, classroom, and site on the prevalence of significant problems. The prevalence of externalizing behaviors in the problem range was higher than expected and fewer children were rated in the well-adjusted range on social competence measures. Psychometric characteristics of the ratings indicated that teachers in this urban setting were less consistent in their ratings of internalizing problems, calling into question the lack of elevation of such problems in this population. Ratings by teachers and teacher assistants of the same children showed low agreement; the level of ratings was not affected by differences in training but did vary across classrooms. Hierarchical linear modeling analyses of the entire sample showed significant effects of classroom and site on problem behaviors and social competence. These results reveal the wide variation in problem frequency across classrooms, which needs to be considered in the implementation and evaluation of evidence-based interventions. Further, these results point to the importance of studying possible lasting effects on children exposed to these differing contexts.
