Accuracy of Dental Age in Nonadults: A Comparison of Two Methods for Age Estimation Using Radiographs of Developing Teeth

This research tests the accuracy of two methods for age estimation, Cameriere's European formula and AlQahtani's London Atlas, on a multi‐population American sample. Digitized radiographs of 360 European American, Hispanic, and American Indian children aged 6–17 years were analyzed. The accuracy of these methods was assessed using the mean and absolute mean difference of the residuals. Results indicate that Cameriere's European formula underestimated age for both sexes, with a mean difference of ?1.19 years for girls and ?1.32 years for boys, prompting the first author to create an American‐specific formula. The London Atlas underestimated age with a mean difference of ?0.18 years for girls and ?0.16 years for boys. Sex and ancestry had no significant affect on accuracy. The results indicate that both methods can be used for age estimation in an American population.     

Taphonomic Analysis of Rodentia and Lagomorpha Bone Gnawing Based Upon Incisor Size

Rodent and lagomorph species have a worldwide distribution and have the potential to alter remains from forensic cases by gnawing soft tissue and bones and through dispersal. The present research compiled metric data on the incisors widths of all rodent and lagomorph species whose ranges include Massachusetts, U.S.A., to compare their sizes to gnawing damage found on 17 cases of human remains from the Office of the Chief Medical Examiner, Boston, MA. Data on gnawing maximum striation widths also were collected from live laboratory, zoo, and wild specimens. Gnawing damage on the forensic cases could be attributed only to a particular size class of rodent or lagomorph, and identification to a particular species based on gnawing damage alone may be possible only in relatively rare cases. Multiple species examined here have broad distribution ranges, so their taphonomic alterations may impact bones from forensic cases throughout large portions of North America.     

Characterization and validation studies of powerPlex 2.1, a nine-locus short tandem repeat (STR) multiplex system and penta D monoplex

In order to increase the power of discrimination for human identification purposes, a nine-locus short tandem repeat (STR) multiplex, the GenePrint PowerPlex 2.1 system (PowerPlex 2.1) developed by Promega Corporation and a separate pentanucleotide-repeat locus, Penta D, were tested. This megaplex system includes the highly polymorphic loci FGA, TPOX, D8S1179, vWA, Penta E, D18S51, D21S11, TH01, and D3S1358 and may be used in combination with the eight-locus STR multiplex, the GenePrint PowerPlex 1.1 system (PowerPlex 1.1) that has been previously developed. Three of the loci, TPOX, TH01 and vWA, have been included in both systems for quality control purposes. As with PowerPlex 1.1, PowerPlex 2.1 is also based on a two-color detection of fluorescent-labeled DNA products amplified by polymerase chain reaction (PCR) and provides a valuable tool for accurate and rapid allele determination. The primer sequences used in the PowerPlex 2.1/Penta D system are also presented in this report. To meet the "Quality Assurance Standards for Forensic DNA Testing Laboratories" (FBI), we tested the efficiency and reproducibility of the PowerPlex 2.1/PentaD system by several validation studies that were conducted as a joint project among seven laboratories. Validation tests included concordance studies, sensitivity, and species specificity determination, as well as performance in forensic and environmentally impacted samples. The results produced from these tests demonstrated the consistency and reliability of the PowerPlex 2.1/Penta D system.     

Body Morph: Feasibility Testing of an Interactive CD-ROM to Teach Young Adolescents about Puberty

The aim of this pilot study was to examine the feasibility of an interactive computer program among 34 sixth and seventh grade children and to assess the potential for knowledge acquisition about puberty. Based on a developmental self-esteem approach to teach children about their bodies, the Body Morph program was designed to maximize the educational experience by: (1) tailoring puberty information to boys or girls, and (2) creating a confidential experience. Preliminary results indicated that students significantly improved their knowledge about puberty after using the program. Satisfaction among boys and girls for this type of educational approach suggests that it is a compelling format from which to learn about puberty.This research project was funded with the support of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) 1R43DK061269-01A2 to develop an educational computer program to improve body image in middle schoolers.     

Effects of Positive Impression Management on the Psychopathic Personality Inventory

The Psychopathic Personality Inventory (PPI; S. O.Lilienfeld & B. P. Andrews, 1996) is a self-report test that has shown considerable promise as a screening measure for psychopathy. A current limitation of the PPI is that no data exist regarding the impact of response sets such as positive impression management. Although the PPI contains a validity scale (Unlikely Virtues) designed to identify response biases such as faking good, its utility has not yet been assessed. In this study a repeated measures analogue design was employed in which 186 respondents completed the PPI both under standard conditions and with specific instructions to create a favorable impression of themselves. In the fake good condition, participants were able to appear significantly less psychopathic, with those who obtained higher scores in the standard instruction condition showing the largest decreases in their PPI scores. Receiver Operating Characteristic analyses indicated that, although the Unlikely Virtues scale significantly differentiated between fake good and honest protocols (area under the curve = .73), a considerable number of misclassifications occurred. The clinical and forensic implications of these findings are discussed.     

Perception vs. Reality: The Relationship Between Organized Crime and Human Trafficking in Metropolitan Atlanta

Since the enactment of the Trafficking Victims Protection Act of 2000, there has been an increase in both media and scholarly discussions of human trafficking. Although most of these discussions have framed human trafficking as a crime committed primarily by organized crime groups, there has been very little empirical research examining the link between human trafficking and organized crime. In an effort to start to address this gap in the research, we conduct an exploratory study to determine if there is a link between human trafficking and organized crime in one of the Southeast’s human trafficking hubs – Atlanta, Georgia. We collected data on 24 federal human trafficking cases that were indicted in metropolitan Atlanta between 2000 and 2013. Then, we conducted a content analysis of the court documents for each federal human trafficking case and classified the relationship between organized crime and human trafficking using one of three categories: nonexistent, organized criminal network, organized criminal syndicate. For the majority of the human trafficking cases (n = 16), we found that there was no relationship between organized crime and human trafficking. For the cases that did show a relationship between organized crime and human trafficking, we found evidence of organized criminal networks in eight of the cases and evidence of an organized criminal syndicate in only one case.     

Woman Suffrage and Irish Nationalism: ethnic appeals and alliances in America

Nationalism first brought Irish-American women into a political struggle in the late nineteenth century, a role that did not go unnoticed by suffragists, who reached out to Irish-Americans through sympathy with the Home Rule movement. These connections also continued into the twentieth century as the crisis of World War I converged with revolutionary nationalism and the final push for suffrage in America. A small group of nationalists and suffragists worked together and sought alliances in an environment where Irish-American men wielded political power and Irish-American women continued to be active in the nationalist movement beyond the Ladies' Land League era.
