Global aspirations.

Aecom Technology Corp. acquired Arlington, Va.-based development services firm Services Group for an undisclosed sum. The Los Angeles-based consulting firm said that the addition of the company will prompt creation of a division that will focus on acquiring international contracts and will be called

Aecom International Development. The new division will have its headquarters in Washington and will specialize in providing support services in emerging markets around the globe, Aecom said. The new unit will employ more than 400 full-time workers. increased Protection: MySpace.com said it has agreed with 49 states and the District of Columbia to add measures to combat sexual predators' access to the popular social-networking Web site. Santa Monica-based MySpace said it will include several online protections as well as development of age-verification and other technologies to prevent sexual offenders and predators from using the site. The Web site, which is owned by News Corp., also said it will allow parents to submit a child's e-mail addresses to MySpace to prevent anyone from using them to set up false profiles and will establish a default for private settings by users under 18 so they cannot be viewed by adults they don't already know. The changes come after a federal grand jury in Los Angeles began issuing subpoenas in the case of a Missouri teenager who hanged herself after being rejected by the person she thought was a 16-year-old boy but was really the mother of one of the girl's former friends.
