The Accuracy and Repeatability of Reconstructing Single Bullet Impacts Using the 2D Ellipse Method

When a bullet punctures a surface, it leaves behind a bullet impact, which can be analyzed in order to determine the origin and trajectory path from which a bullet was discharged using many different scientific methods to reconstruct a shooting scene. The purpose of the research was to test the accuracy and repeatability of reconstructing the impact angle of single bullet impacts using the ellipse method. The research was conducted by firing various calibers of ammunition into drywall panels positioned at varying angles of incidence from 88° until ricochet occurred. This was done in order to determine which caliber type and angle of incidence are most accurate and precise for reconstructing a shooting scene. The study examined four caliber types fired into drywall panels, with 5 repeated shots for each of the 11 angles of incidence (n = 220). Furthermore, 31 participants partook in the study to estimate a bullet impact angle of incidence utilizing the ellipse method. The results show that the best performance (accuracy and repeatability) is seen with the measurements of the 0.45 caliber ammunition. When angle of incidences is low (<64°), the performance (accuracy and repeatability) was seen to be better in all caliber ammunitions. Overall, the data provided for single bullet impacts deposited in drywall show that the ellipse method is useful in providing measurements for most crime scene reconstruction purposes and has also demonstrated that results vary depending on the type of ammunition, firearm, and angle of incidence being examined.     

Sales and Use Tax Simplification and Voluntary Compliance

Because of difficulties collecting sales taxes on Internet sales, several states have engaged in an effort (the Streamlined Sales Tax Project, SSTP) to simplify their sales tax systems. One hope among SSTP proponents is that a simplified system will result in Internet vendors voluntarily collecting the sales tax. We address two issues:

• ? Will states adopt the extensive reforms proposed by the SSTP?
• ? Will vendors voluntarily collect the sales tax?

We argue that states are unlikely to adopt extensive reforms, but if they did, many vendors would voluntarily collect sales taxes.     

Building the Evidence Base for Intensive Family Preservation Services

This article examines the state of intensive family preservation services (IFPS) research. Using studies of IFPS in five states, this article seeks to establish whether IFPS can be regarded as an evidence-based practice, an increasingly important standard for publicly funded services. While reporting rates of repeat child maltreatment, the analysis uses placement rates as the main outcome measure and compares effect sizes using Cohen's arcsine transformation for data reported as proportions. Significant differences in rates of child out-of-home placement and repeat maltreatment were found in some studies, particularly for higher risk families. The findings also underscore the difficulty of identifying which families to serve (targeting), ensuring treatment fidelity, and employing rigorous and appropriate evaluation methods. Overall, additional research is needed to move IFPS from a promising practice to an evidence-based practice.     

The incest offender,power, and victimization: Scales on the same dragon

It is contended that incest is a specific case of a larger problem, that being inappropriate use of power, resulting in victimization of a weaker person. The article is primarily an exploration of ideas regarding root causes of such victimization. It is proposed that implied ownership is present in certain traditional family constellations in our society. It is further proposed that many factors, including this implied ownership, contribute to a profound lack of empathy on the part of the offender. Numbered among these factors are our individualistic, compartmentalized culture, developmental deficits, and overt choices on the part of the offender. Concluding comments call for further reflection and attention to the issues raised, with suggestions regarding important areas for focus and investigation.     

Effect of test administration set on the Psychological Inventory of Criminal Thinking Styles (PICTS)

The Psychological Inventory of Criminal Thinking Styles (PICTS) was administered to 160 male prisoners on admission to a medium-security federal correctional facility. A total of 106 of these inmates completed the PICTS a second time 6 months later in a routine follow-up of the intake PICTS; the other 54 inmates completed the PICTS a second time approximately 6 months later during the initial session of a psychological group. Results showed that inmates participating in the psychological group were less defensive and endorsed more criminal thinking items on the second administration of the PICTS, whereas inmates participating in the routine follow-up were more defensive and less likely to endorse criminal thinking items on the second PICTS. Despite a general increase in the magnitude of PICTS scores for program participants, the overall pattern of scale elevations (correlations between scales and high-point pairs) was comparable across the two groups.     

Criminal thinking as a moderator of the perceived certainty–offending relationship: age variations

ABSTRACT

The purpose of this study was to determine whether the perceived certainty of punishment and general criminal thinking interact and whether the effect varies as a function of age. Data from all 1354 members (1170 males, 184 females) of the Pathways to Desistance study were used to test whether perceived certainty, general criminal thinking, and their interaction predicted subsequent offending during late adolescence (16–18 years of age) and emerging adulthood (20–22 years of age). The results showed that while perceived certainty and general criminal thinking failed to interact at age 17, general criminal thinking moderated the effect of perceived certainty at age 21. During emerging adulthood, offending was more common and varied in young adults with low certainty perceptions and high criminal thinking than it was in emerging adults with high criminal thinking and high certainty perceptions or low criminal thinking and either high or low certainty perceptions.
