Recovery of Environmental Human DNA by Insects*,†

Abstract: We tested the hypotheses that foraging insects can acquire human DNA from the environment and that insect‐delivered human DNA is of sufficient quantity and quality to permit standard forensic analyses. Houseflies, German cockroaches, and camel crickets were exposed to dusty surfaces and then assayed for human mitochondrial and nuclear loci by conventional and qPCR, and multiplex STR amplification. Over two experiments, 100% of insect groups and 94% of dust controls tested positive for human DNA. Of 177 individuals, 33–67% tested positive and 13 yielded quantifiable human DNA (mean = 0.022 ± 0.006 ng; mean dust control = 2.448 ± 0.960 ng); four had at least one positive allele call for one or more locus; eight others showed multiple peaks at some loci. Results imply that application to routine forensic casework is limited given current detection methodology yet demonstrate the potential use of insects as environmental samplers for human DNA.     

An Integrated Model of Legal and Moral Reasoning and Rule-Violating Behavior: The Role of Legal Attitudes

Legal socialization theory predicts that attitudes mediate the relation between legal reasoning and rule-violating behavior [Cohn, E. S., & White, S. O. (1990). Legal Socialization: A Study of Norms and Rules. New York: Springer-Verlag]. Moral development theory predicts that moral reasoning predicts rule-violating behavior directly as well as indirectly [Blasi, A. (1980). Bridging moral cognition and moral action: A critical review of the literature. Psychological Bulletin, 88, 1–45]. We present and test an integrated model of rule-violating behavior drawing on both theories in a longitudinal study of middle school and high school students. Students completed questionnaires three times during the course of 1 year at 6-month intervals. Legal and moral reasoning, legal attitudes, and rule-violating behavior were measured at times one, two, and three respectively. Structural equation models revealed that while moral and legal reasoning were directly and indirectly related to rule-violating behavior among high school students, legal reasoning bore no direct relation to rule-violating behavior among middle school students. The implications for an integrated model of reasoning and rule-violating behavior are discussed.

A Prototype of Mathematical Treatment of Pen Pressure Data for Signature Verification

A prototype using simple mathematical treatment of the pen pressure data recorded by a digital pen movement recording device was derived. In this study, a total of 48 sets of signature and initial specimens were collected. Pearson's correlation coefficient was used to compare the data of the pen pressure patterns. From the 820 pair comparisons of the 48 sets of genuine signatures, a high degree of matching was found in which 95.4% (782 pairs) and 80% (656 pairs) had rPA > 0.7 and rPA > 0.8, respectively. In the comparison of the 23 forged signatures with their corresponding control signatures, 20 of them (89.2% of pairs) had rPA values < 0.6, showing a lower degree of matching when compared with the results of the genuine signatures. The prototype could be used as a complementary technique to improve the objectivity of signature examination and also has a good potential to be developed as a tool for automated signature identification.     

Malingered Posttraumatic Stress Disorder (PTSD) and the Effect of Direct Versus Indirect Trauma Exposure on Symptom Profiles and Detectability

Posttraumatic stress disorder (PTSD) is arguably prone to malingering due to its subjective and heterogeneous nature. Various factors can influence PTSD symptom profiles including trauma type and trauma exposure. However, it is unknown whether trauma exposure influences malingered PTSD symptom profiles. We used a malingering simulation design with trauma type controlled to compare (1) PTSD symptom profiles (Posttraumatic Stress Checliklist-5; PCL-5) at the syndrome, symptom cluster, and individual symptom levels and (2) symptom validity profiles (Structured Inventory of Malingered Symptomatology; SIMS) at the overall and subscale level, as a function of direct and indirect trauma exposure. Seventy-three participants were randomly assigned to either the direct (“witnessed” trauma) or indirect (“learned about” trauma) condition. Participants were coached about symptoms and instructed to simulate PTSD. PCL-5 profile analyses revealed that simulators in the direct exposure group reported greater overall PTSD severity. Significant differences were found on cluster D (changes in cognition and mood) and individual symptoms including intrusive thoughts, amnesia, difficulty experiencing positive emotions, and risk-taking. No differences were identified for any other symptom scores nor for the symptom validity profile, except for the SIMS total score (direct: M?=?33.0, SD?=?12.8, indirect: M?=?26.5, SD?=?13.9, t(71)?=?2.06, p?=?.043, d?=?.48). These findings indicate that trauma exposure can influence malingered PTSD profiles at the syndrome, symptom cluster, and individual symptom levels (small effects), but, with one exception for a summary score, it does not produce a detectable difference on symptom validity testing. This study may provide insight for clinicians into the how malingered PTSD profiles can manifest as a result of direct and indirect trauma exposure; however, further research is strongly indicated.
