The Future of Consumer Web Data: A European/US Perspective

The article considers the subject of clickstream data from aEuropean/US perspective, taking into account the Data ProtectionFramework (Data Protection Directive 95/46/EC; Directive onPrivacy and Electronic Communications 2002/58/EC) and the USlegal framework and in particular, the Wiretap Act U.S.C. 2701(2004) and related statutes. It examines the extent to whichclickstream data is considered "personal data" within the DataProtection Directive and the implications to consumers and businesses.     

A Longitudinal Study of Modifying Influences in the Relationship Between Domestic Violence and Child Maltreatment

The increased risk of child maltreatment in the presence of domestic violence is well documented, but much remains unknown about factors that modify this relationship. This study investigates the roles of risk and protective factors in the relationship between domestic violence and being reported to the Department of Social Services for child maltreatment. Consistent with the literature, we find a significant overlap between domestic violence and maltreatment. Young maternal age, low education, low income, and lack of involvement in a religious community add to the risk for maltreatment associated with domestic violence. Separation between the maternal caregiver and her partner significantly reduces the risk for maltreatment when domestic violence is reported. A significant reduction in the risk for maltreatment is also found with higher levels of support from the maternal caregiver reported by the child in the context of domestic violence.     

THE ECOLOGY OF GANG TERRITORIAL BOUNDARIES*

Within any type of system, the actors in the system inevitably compete over resources. With competition comes the possibility of conflict. To minimize such effects, actors often will partition the system into geographic territories. It is against the larger ecological backdrop of competition and conflict that we examine territory formation among urban street gangs. Although previous studies have examined the social and built environment where gangs form, and how the presence of a gang influences local levels of violence, we know little about how competitive interactions are tied to the formation and maintenance of gang territories. We use formal spatial Lotka–Volterra competition models to derive hypotheses about competition‐driven territory formation. By using data on 563 between‐gang shootings, involving 13 rival street gangs in the Hollenbeck Policing Division of Los Angeles, we show that violence strongly clusters along the boundaries between gangs in a way that is quantitatively predicted by the theory. The results suggest that even weak competitive interactions between gangs are sufficient to drive gang territory formation without recourse to other processes or assumptions.
