Protecting children from sex offenders online: when strangers become 'virtual friends'

This article describes findings from research funded by the Metropolitan Police and Crimestoppers which aimed to explore children's online experiences. A non-random, stratified sample of 200 London school children aged 10- 13 participated in focus groups. Preliminary findings are also presented from unpublished ongoing PhD research, which seeks to explore sex offender behaviour online and the policing of the internet (Martellozzo, 2005 ongoing). The findings are discussed in the context of sex offender's use of the internet. This research indicates that children do have some basic knowledge about 'stranger danger' but are not necessarily applying these lessons to cyberspace. The children in this study had sufficient awareness to not give personal details to strangers on the internet, and would not arrange to meet them. However, they made a distinction between 'strangers' and 'virtual friends' and this is an important point. Preliminary findings also highlight the difficulty of policing the internet and serve to illustrate the manner in which the Sexual Offences Act 2003 is applied to internet sexual offending in practice.

Sexual dimorphism in relation to adipose tissue and intrahepatocellular lipid deposition in early infancy

Sexual dimorphism in adiposity is well described in adults, but the age at which differences first manifest is uncertain. Using a prospective cohort, we describe longitudinal changes in directly measured adiposity and intrahepatocellular lipid (IHCL) in relation to sex in healthy term infants. At median ages of 13 and 63 days, infants underwent quantification of adipose tissue depots by whole-body magnetic resonance imaging and measurement of IHCL by in vivo proton magnetic resonance spectroscopy. Longitudinal data were obtained from 70 infants (40 boys and 30 girls). In the neonatal period girls are more adipose in relation to body size than boys. At follow-up (median age 63 days), girls remained significantly more adipose. The greater relative adiposity that characterises girls is explained by more subcutaneous adipose tissue and this becomes increasingly apparent by follow-up. No significant sex differences were seen in IHCL. Sex-specific differences in infant adipose tissue distribution are in keeping with those described in later life, and suggest that sexual dimorphism in adiposity is established in early infancy.
