Observations Regarding Key Operational Realities in a Compstat Model of Policing

With nearly 4 million adults under supervision in the US, probationers make up the largest group of offenders under the supervision of the criminal justice system. Yet the sanction of probation has received relatively little study. Because probation is generally a local endeavor, coordinated data collection is rare. In this article, the changing dynamics of felony probation populations in California over two decades are examined using dynamic systems simulation modeling. In addition to demonstrating the utility of this underused modeling technique, the legal and social sources of changes in the use of felony probation in California’s criminal justice system are discussed, as are the practical and policy implications of these changes.

Polymorphism of four X-chromosomal STR loci in Belarusians and Slovaks

We have investigated four X-chromosomal STR loci (a tetranucleotide repeat marker HPRTB, DXS7423 and trinucleotide repeat systems DXS101, DXS8377) in population samples of unrelated Belarusian and Slovak males (N = 180 and 116, respectively).Markers were amplified in a multiplex PCR reaction with primers labeled with fluorescent dyes 5-FAM and 5-JOE (dye set F). The separation and detection of PCR products were performed by capillary electrophoresis on a 3130 Genetic Analyzer (Applied Biosystems), using positive controls (K562 and NA9947A) and the GeneScan-500 ROX internal lane standard. Allele designation was based on comparison with the constructed allelic ladder. We performed statistical analysis estimating power of discrimination for males (PD_male). Our data was compared with European populations from Poland and Germany. The obtained data are useful in forensic practice and they contribute to creation of national X-STR databases in Belarus and Slovakia.     

Genetic analysis of the Amerindian Kichwas and Afroamerican descendents populations from Ecuador characterised by 15 STR-PCR polymorphisms

Allele frequency data for the 15 STR systems and Amelogenine were determined in a population sample of healthy Amerinidian Kichwas and Blacks individuals. All loci met Hardy–Weinberg expectations and the high discrimination power of combined system showed the forensic efficiency of these genetic markers.     

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.

Y-chromosome STR haplotypes in a sample from São Paulo State, southeastern Brazil

Population: Unrelated males from the S?o Paulo State, Brazil (n=617).     

Population data for a novel, highly discriminating tetra-local Y-chromosome short tandem repeat: DYS503

Population: Population samples for gene diversity studies were obtained from the Virginia Division of Forensic Science (bloodstains), Richmond, VA. Ninety-eight Caucasian and 100 African American samples were included in this study.
