This paper addresses issues in the literature regarding the co-occurrence of partner and child physical maltreatment in the United States and in Europe. Design issues including operationalizations, representativeness of samples, data collection methods, and reference periods are discussed in the context of prevalence studies. Next, possible explanations for the pervasiveness of co-occurring maltreatment are explored with an emphasis on theoretical models and mechanisms of co-occurrence. Finally, we offer assessment implications for clinicians and agencies dealing with partner and child maltreatment

Granule cells of the mammalian dentate gyrus normally form a discrete layer, and virtually all granule cells migrate to this location. Exceptional granule cells that are positioned incorrectly, in 'ectopic' locations, are rare. Although the characteristics of such ectopic granule cells appear similar in many respects to granule cells located in the granule cell layer, their rare occurrence has limited a full evaluation of their structure and function. More information about ectopic granule cells has been obtained by studying those that develop after experimental manipulations that increase their number. For example, after severe seizures, the number of ectopic granule cells located in the hilus increases dramatically. These experimentally-induced ectopic granule cells may not be equivalent to normal ectopic granule cells necessarily, but the vastly increased numbers have allowed much more information to be obtained. Remarkably, the granule cells that are positioned ectopically develop intrinsic properties and an axonal projection that are similar to granule cells that are located normally, i.e., in the granule cell layer. However, dendritic structure and synaptic structure/function appear to differ. These studies have provided new insight into a rare type of granule cell in the dentate gyrus, and the plastic characteristics of dentate granule cells that appear to depend on the location of the cell body

This article presents the results of a study examining correlates of urban African American youth HIV knowledge. The influence of family level factors (e.g., family communication, parental AIDS knowledge and myths regarding HIV transmission, along with family composition and family income) are examined. In addition, the current study explores the influence of racial socialization processes, specifically the influence of religious/spiritual coping, extended family caring, cultural pride reinforcement and racial awareness teaching (Stevenson, 1994; 1995; 1997) on youth HIV knowledge. Multivariate analyses revealed a significant association between youth HIV knowledge and being reared in a single parent home. Further, in every model, controlling for all types of racial socialization processes, family communication was significantly associated with youth HIV knowledge. Implications are drawn regarding the development of culturally and contextually specific HIV prevention programming for African American youth and their families

Two curricula designed to enhance the early literacy skills of 4-year-old preschool children were evaluated against a third, comparison condition. Thirty-five Head Start preschool classrooms were assigned randomly to incorporate one of two early literacy curricular approaches, Let's Begin with the Letter People (R) or Waterford Early Reading Program (R) Level 1, into their current curriculum, the High/ Scope (R) Educational Approach, or to use the High/Scope method alone. Results indicated that children in the literacy intervention classrooms demonstrated significantly stronger outcomes in the areas of emergent writing, book and print knowledge, and general reading readiness skills. Minority language status also played a significant role in outcome, regardless of intervention condition. Implications for early childhood literacy interventions, especially important for children of low-income families, are discussed.

Object recognition is a crucial component of both visual and auditory perception. It is also critical for olfaction. Most odours are composed of 10s or 100s of volatile components, yet they are perceived as unitary perceptual events against a continually shifting olfactory background (i.e. figure-ground segregation). We argue here that this occurs by rapid central adaptation to background odours combined with a pattern-matching system to recognise discrete sets of spatial and temporal olfactory features-an odour object. We present supporting neuropsychological, learning, and developmental evidence and then describe the neural circuitry which underpins this. The vagaries of an object-recognition approach are then discussed, with emphasis on the putative importance of memory, multimodal representations, and top-down processing
