This paper reports a method for the determination of the firing distance. Atomic absorption spectroscopy (AAS) was used to determine the lead (Pb) pattern around bullet holes produced by shots on test targets from the gun. Test shots were made with a Colt 38 Special at 5, 10, 20, 25, 30, 35, 40, 45, 50, 60, 80, and 100 cm target distance. The target was created with sheets of Whatman no. 1 paper on a polystyrene support. The target was subdivided into three carefully cut out rings (1, 2, and 3; with external diameters of 1.4 cm; 5 cm; 10.2 cm, respectively). Each sample was analyzed with graphite furnace AAS. Lead values analysis performed for each ring yielded a linear relation between the firing distance (cm) and the logarithm of lead amounts (microg/cm(2)) in definite target areas (areas 2 + 3): [ln dPb(2+3) = a(0) + a(1)l]; where dPb(2+3) = lead microg/cm(2) of area 2 + 3; a(0) and a(1) are experimentally calculated; l = distance in cm. 相似文献

A New Index for the MMPI‐2 Test for Detecting Dissimulation in Forensic Evaluations: A Pilot Study 下载免费PDF全文
Vito Martino M.D. Ignazio Grattagliano Psy.D. Andrea Bosco Ph.D. Ylenia Massaro Psy.D. Andrea Lisi Ph.D. Filippo Campobasso Psy.D. Maria Alessia Marchitelli M.A. Roberto Catanesi M.D. 《Journal of forensic sciences》2016,61(1):249-253
This pilot study is the starting point of a potentially broad research project aimed at identifying new strategies for assessing malingering during forensic evaluations. The forensic group was comprised of 67 males who were seeking some sort of certification (e.g., adoption, child custody, driver's license, issuance of gun permits, etc.); the nonforensic group was comprised of 62 healthy male volunteers. Each participant was administered the MMPI‐2. Statistical analyses were conducted on obtained scores of 48 MMPI‐2 scales. In the first step, parametric statistics were adopted to identify the best combination of MMPI‐2 scales that differentiated the two groups of participants. In the second step, frequency‐based, nonparametric methods were used for diagnostic purposes. Results: A model that utilized the best three predictors (“7‐Pt”, “L,” and “1‐Hs”) was developed and used to calculate the Forensic Evaluation Dissimulation Index (FEDI), which features satisfactory diagnostic accuracy (0.9), sensitivity (0.82), specificity (0.81), and likelihood ratio indices (LR+ = 4.32; LR? = 0.22). 相似文献

Many studies have examined the characteristics of the frontal sinuses and their use for forensic purposes, particularly when an individual is edentulous. One of the most widespread classification systems is that proposed by Yoshino et al. The aim of this study was to improve the performance of Yoshino's method for identifying unknown skeletal remains by replacing the first two morphological items, frontal sinus size and bilateral asymmetry, by SOR1 = left frontal sinus area/left orbit area, and SOR2 = right frontal sinus area/right orbit area. According to the bivariate distribution of SOR = (SOR1, SOR2) and available data, we also estimated the probability of positive misclassification. 相似文献

In southern Chile, Mapuche Indigenous communities are using video and digital filmmaking to collectively reflect on and communicate knowledge. This article shares their experience, arguing that with the increasing accessibility of information and communication technologies, we should be rethinking and broadening the acceptable ways to generate and convey knowledge about development. Acknowledging the diverse ways of knowing and communicating knowledge, this article suggests that video can be a powerful tool for self-representative knowledge-sharing by Indigenous communities. Only by expanding our debates beyond written media can we engage equitably with a plurality of knowledge-holders to resolve development challenges. 相似文献

Homeownership is the primary way most families build wealth in this country. Low-income homeowners are less likely to get that benefit because they are more likely to own older houses that are more costly to operate and need more essential maintenance. Rapidly escalating home energy costs are straining the budgets of many low-income homeowners, increasing the likelihood of under maintenance and mortgage default. This paper presents an evaluation of a demonstration program designed to coordinate weatherization and rehabilitation programs in order to assist low-income households, decrease energy costs, and to improve the condition and value of their homes. The experience of 11 local non-profit organizations, funded to develop programs to coordinate weatherization and housing rehabilitation services, were studied over a five-year period. The results of the evaluation indicate that there are many obstacles to coordinating weatherization and rehabilitation programs, but that it can be accomplished under the right conditions. Major gaps exist between program eligibility thresholds and in the types of assistance available to low-income homeowners. Policy recommendations for facilitating coordination are presented. 相似文献

Abstract Homeownership counseling encompasses several educational activities. Early approaches focused on reducing the risk of default and foreclosure among participants in government‐assisted mortgage programs, but more recent approaches have focused on increasing homeownership opportunities among low‐income and minority households. Unfortunately, little is known about the effectiveness of these approaches in terms of the number of new homeowners and the mitigation of default risk. To address that gap, this article presents a theoretical and methodological framework to evaluate counseling efforts. A successful counseling program is defined as one that assists a household with a low long‐term probability of ownership in buying a home and reducing its default risk. We concede that the methodological requirements for evaluating counseling are somewhat restrictive. However, if we establish an evaluation procedure using these goals as a framework, we can more accurately determine the effects of counseling on the sustainability of low‐income homeownership. 相似文献
