Distorted maternal mental representations and atypical behavior in a clinical sample of violence-exposed mothers and their toddlers

Objective: To determine whether maternal violence-related posttraumatic stress disorder (PTSD), reflective functioning (RF), and/or quality of mental representations of her child predicts maternal behavior within a referred sample of mothers exposed to interpersonal violence and their children (aged 8–50 months). Method: A total of 41 dyads completed 2 videotaped visits including measures of maternal mentalrepresentations and behavior. Results: Negative and distorted maternal mental representations predicted atypical behavior (Cohen’s d \u3e 1.0). Although maternal PTSD and RF impacted mental representations, no significant relationships were found between PTSD, RF, and overall atypical caregiving behavior. Severity of maternal PTSD was, however, positively correlated with the avoidant caregiving behaviorsubscale. Conclusions: Maternal mental representations of her child are useful risk indicators that mark dysregulation of trauma-associated emotions in the caregiver

A taxonomic study of two nominal subspecies of pikas (Ochotona princeps) in the Cascade Mountains of Oregon

Pikas from four colonies in the Cascade Mountains of Oregon were examined. Two colonies were chosen from within the geographical distribution of two nominal subspecies. A discriminate analysis of morphological measurements taken from the specimens showed that each colony could be distinguished from each other. Each colony studied showed more intra-colony similarity than inter-colony similarity regardless of distance separating the colonies or subspecies designations. The results indicate that the validity of subspecies designations for this species can be questioned

endo,endo-Tetracyclo[6.2.1.13,6.02,7]dodeca-9-en-anti-11-yl 4-bromobenzoate

The title compound 1-OPBB, C19H19BrO2, contains a dechlorinated and hydrogenated isodrin backbone with an anti-4-bromobenzoate substituent at one of the methano bridges. The dihedral angle between the CO2 ester plane and the benzene ring plane is 8.5 (2)°. In the crystal, the ester groups stack over benzene rings: the molecules pack as conformational enantiomers, with nearest parallel benzene ring planes separated by a perpendicular distance of 3.339 (1) Å. The nearest benzene-ring centroids are 5.266 (1) Å apart. Possible structural correlation with enhanced solvolytic reactivity is investigated
