Validation and casework application of a Y chromosome specific STR multiplex

A series of validation experiments was performed for a Y chromosome specific STR multiplex system following the suggestions made by the Technical Working Group DNA Analysis Methods (TWGDAM). The multiplex PCR products were detected on Perkin-Elmer 373 and 377 automated sequencers using two labeling colors. No problems regarding the stability, robustness and sensitivity of the Y STR multiplex were observed. Mixture studies revealed a cut off rate similar to autosomal STRs for mixtures of male DNAs and no interference of any female admixture. The comparison of the Y STR results to the autosomal typing results for 56 nonprobative semen stains and swabs, showed a slightly higher success rate in detecting the semen donor’s alleles for the Y STR multiplex. Two examples are shown to illustrate the usefulness of Y STR typing for DNA mixtures. In one case the Y STR results confirmed an isolated exclusion; in the other case, the interpretation of a mixture was clarified since the Y STR results proved the presence of DNA from at least two semen donors. Y STR typing is a valuable addition to the forensic DNA testing panel.     

When does science persuade (or not persuade) in high-conflict policy contexts?

Researchers struggle to understand the relationship between science and policy positions, especially the complicated interplay among the various factors that might affect the acceptance or rejection of scientific information. This article presents a typology that simplifies and guides research linking scientific information to policy positions. We use the typology to examine how characteristics of both scientific information and policy actors' existing policy positions affect the likelihood of changing, maintaining or reinforcing those policy positions. We analyse data from surveys conducted in 2015 and 2017 of policy actors engaged in contested policy debates over shale oil and gas development in Colorado, US. Our findings confirm expectations that policy actors will most likely maintain and reinforce their policy positions in response to scientific information. Our data also show that changes in policy positions depend on policy actors' risk perceptions, perceived issue contentiousness, networks and experience with science.     

Role call: sex,gender roles,and intimate partner violence

ABSTRACT

Intimate partner violence (IPV) continues to be viewed in gendered and heteronormative ways. Stanziani, Cox, and Coffey (2018, Adding insult to injury: Sex, sexual orientation, and juror decision-making in a case of intimate partner violence. Journal of Homosexuality, 65(10), 1325–1350) presented participants with a case of alleged IPV while manipulating the sex and sexual orientation of the aggressor/victim dyad. Results suggested participants view violence perpetrated by a man against a woman most abhorrently. The current study replicated and expanded that study, exploring how gender role beliefs influence participant decision-making. Female participants held more adverse attitudes towards IPV when a male assaulted a female. Further, participant gender role beliefs influenced decision-making. Specifically, males who endorsed higher levels of hegemonic masculinity perceived the crime to be less serious, while females who endorsed the same beliefs perceived the defendant as less likely to benefit from treatment. Overall, results suggest individual beliefs regarding gender roles and masculinity may influence their perceptions of IPV, regardless of the gender and sexual orientation of the aggressor and victim.     

The two faces of nation‐building: developing function and identity

Nation‐building is an age‐old process being implemented in new ways. It consists of two separate aspects: state‐building implemented by external actors and identity‐building implemented by grassroots actors within the state itself. However, a functioning state is a necessary precondition for identity‐building because it allows for the development of a civic identity that can incorporate group identities and create a shared sense of community. When a unifying and legitimate state structure is absent, group identifications will remain strong and counteract internal efforts at nation‐building. Unfortunately, the record of nation‐building when understood as both state‐ and identity‐building is relatively poor. The failure of international efforts to create stable states inhibits development of a civic identity and reinforces fragmentation. That in turn brings the longevity of the state into question by raising the possibility that dissatisfied groups will again turn to violence. Learning how to develop both aspects of nation‐building more effectively is an important challenge for international actors.     

Family profiles of adaptability,cohesion, and communication for learning handicapped and nonhandicapped adolescents

The family functioning of 30 nonhandicapped and 30 learning handicapped adolescents and their parents was examined. Measures of adaptability, cohesion, and communication were taken from the parent and the adolescent perspectives. Parent and adolescent perspectives on these areas of functioning were analyzed with a cluster analytic technique, which resulted in five distinct profiles of family functioning. These statistical groupings were confirmed by information gathered through participant observation from an accompanying investigation. The nature of the five clusters confirmed the existence of similar family functioning across the nonhandicapped and learning handicapped groups. Additionally, variations in reaction and adjustment to the amount of structure in the family environment by different families was documented. The importance of considering adolescent and parent perspectives separately was highlighted.Received degree from University of California, Riverside. Research interests are in the area of the social development of at-risk or mildly handicapped children and adolescents in school and family settings.Received degree from Teachers College, Columbia University. Research interests in social competence and family relations of learning handicapped populations as well as the development of family, community, and school partnerships.
