Development of a Validity Scale for the Dissociative Experience Scale-Revised: Atypicality,Structure, and Inconsistency

Psychological Injury and Law - The Dissociative Experiences Scale (DES), the most commonly used scale for assessing dissociation across settings, lacks a validity scale. In this study, six methods...     

Lip print enhancement: review

Lip print(LP)evidence can be an essential tool for human forensics.LPs have conventionally been developed using substances such as lysochrome dyes,fluorescent dyes,indigo dye,aluminium powder,and silver metallic powder.However,techniques for LP enhancement from various substrates are currently inconsistent and lack standardisation in practice.This review summarises current knowledge on the physical and chemical techniques of LP enhancement,identifies limitations,and provides suggestions for future research on practical applications of cheiloscopy as a forensic tool in criminal justice.     

An improved method for post-PCR purification for mtDNA sequence analysis

Mitochondrial DNA (mtDNA) analysis of forensic samples typically is performed when the quantity and quality of DNA are insufficient for nuclear DNA analysis or when maternal relatives may be the only reference source. Many of the steps required in the analytical process are both lengthy and labor intensive. Therefore, improvements in the process that reduce labor without compromising the quality of the data are desirable. The current procedure requires purification of the amplicons by centrifugal filtration after PCR and prior to cycle sequencing. Because this method requires several manipulations to perform, alternate cleanup procedures were investigated. These include the use of 1) Qiagen QlAquick PCR Purification columns, 2) Concert Rapid PCR Purification columns, and 3) ExoSAP-IT reagent. When the yield of purified amplicons, quality of the sequence profile, and ease of assay were evaluated, the use of ExoSAP-IT reagent for post-amplification purification was chosen to replace the filtration method.     

Residential setting and parent-adolescent relationships during the college years

The relationship of residential setting (living with parents vs. living away from home while attending college) and gender with late adolescents' perceptions of their relationships with parents was examined. Four hundred four undergraduates students (mean age=20 years, 4 months) from two midwestern universities completed surveys. Two hundred four subjects lived with their parents and commuted to school, and 200 lived away at college. Controlling for student's age, parents' education, and financial and family considerations as factors in the choice of a college, living away was associated with greater independence, support, and mutual respect between parents and adolescents. In contrast, students who lived at home felt parents underestimated their maturity, and reported more conflict and avoidance in their relationships with parents. Regardless of residential setting, women reported more mutuality and support in their relationships with parents than men. The results suggest the importance of considering contextual issues during the transition to adulthood.This research was supported by a Campus Grant to the first author from the University of Michigan-Dearborn.Received Ph.D. in developmental psychology from the University of Michigan. Research interests include family relationships, cross-cultural studies, and political development in adolescence and young adulthood.Received Ph.D. in human development and family studies from Penn State University. Research interests include competence during the transition to young adulthood, career development, drug and alcohol use.Research interests include adolescents' relationships with parents and peers and cross-cultural studies.     

Quantification of human mitochondrial DNA using synthesized DNA standards

Successful mitochondrial DNA (mtDNA) forensic analysis depends on sufficient quantity and quality of mtDNA. A real-time quantitative PCR assay was developed to assess such characteristics in a DNA sample, which utilizes a duplex, synthetic DNA to ensure optimal quality assurance and quality control. The assay's 105-base pair target sequence facilitates amplification of degraded DNA and is minimally homologous to nonhuman mtDNA. The primers and probe hybridize to a region that has relatively few sequence polymorphisms. The assay can also identify the presence of PCR inhibitors and thus indicate the need for sample repurification. The results show that the assay provides information down to 10 copies and provides a dynamic range spanning seven orders of magnitude. Additional experiments demonstrated that as few as 300 mtDNA copies resulted in successful hypervariable region amplification, information that permits sample conservation and optimized downstream PCR testing. The assay described is rapid, reliable, and robust.     

Differentiating Between Generally and Partner-Only Violent Subgroups: Lifetime Antisocial Behavior,Family of Origin Violence,and Impulsivity

The present study examined self-reported lifetime antisocial behavior, family of origin violence, and impulsivity/behavioral disinhibition of 73 men entering treatment for partner violence. Participants were designated as generally violent (GV) (n = 46) or partner only violent (n = 27), based on self-reported violence against non-intimate individuals during the year prior to intake. As hypothesized, GV men reported more conduct disorder/delinquent behaviors, lifetime antisocial behaviors, and family of origin violence. The GV men also reported more behavioral disinhibition, however, group differences on impulsivity only approached statistical significance. In addition, as hypothesized, GV men reported they were more psychologically abusive toward their intimate partners. However, contrary to expectations, the subgroups did not differ on reports of physical violence toward their partners. This study employed a fairly simple technique of dividing men into groups based on self-reports of violence over the past year, thereby producing subgroups that differed on a number of important characteristics that may have implications for treatment. An advantage of this technique is that it would be relatively easy for other treatment programs to apply.

Defining a Moment in History: Parent Communication with Adolescents About September 11, 2001

Parents play an important role in helping their children process and interpret significant sociohistorical events. However, little is known about how parents frame these experiences or the specific social, cultural, and civic messages they may communicate about the event. In this study, we examined self-reported communication of parents from six communities in the United States with their adolescents about the September 11, 2001 terrorist attacks. Parents’ (N = 972) open-ended responses about September 11th were analyzed to assess whether communication with their adolescents occurred and for thematic content. Results revealed marked variability in parents’ communication and suggest that many parents used September 11th as an opportunity to impart sociocultural, emotional, and civic messages. Identifying the diversity in parents’ responses aligns with the tenets of Terror Management Theory and provides insights into the roles of parents in translating pivotal historical moments. Collectively, these findings yield important implications for civic socialization.
