Spatial Analysis of North Central Texas Traffic Fatalities 2001-2006

Description: A traditional two dimensional (planar) statistical analysis was used to identify the clustering types of North Central Texas traffic fatalities occurring in 2001-2006. Over 3,700 crash locations clustered in ways that were unlike other researched regions. A two dimensional (x and y coordinates) space was manipulated to mimic a one dimensional network to identify the tightest clustering of fatalities in the nearly 400,000 crashes reported from state agencies from 2003-2006. The roadway design was found to significantly affect crash location. A one dimensional (linear) network analysis was then used to measure the statistically significant clustering of flow variables of after dark crashes and daylight crashes. Flow variables were determined to significantly affect crash location after dark. The linear and planar results were compared and the one dimensional, linear analysis was found to be more accurate because it did not over detect the clustering of events on a network.

Child Fatalities from Maltreatment: National Data Could Be Strengthened

Description: Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses child fatalities from maltreatment. Every year, children in the United States die after being physically abused, severely neglected, or otherwise maltreated, frequently at the hands of their parents or others who are entrusted with their care. Infants and toddlers are the most vulnerable to such abuse and neglect. According to estimates by the National Child Abuse and Neglect Data System (NCANDS), 1,770 children in the United States died from physical abuse or other forms of maltreatment in fiscal year 2009. Some experts believe that more children have died from maltreatment than are captured in this estimate and that there are inconsistencies and limitations in the data that states collect and report to NCANDS. In addition, many more children are severely harmed and may nearly die from maltreatment, but NCANDS does not collect data specifically on near-fatalities. The Department of Health and Human Services (HHS) maintains NCANDS, which is a voluntary state data-reporting system. HHS provides oversight of state child welfare systems, and in all states, child protective services (CPS) is part of the child welfare system. When state CPS investigators determine that a child's death is considered maltreatment under state laws or policies, CPS documents the case, and the state's child welfare department reports it to NCANDS. This testimony today is based on our July 2011 report, which is being publicly released today and addresses three issues: (1) the extent to which HHS collects and reports comprehensive information on child fatalities from maltreatment; (2) the challenges states face in collecting and reporting information on child fatalities from maltreatment to HHS; and (3) the assistance HHS provides to states in collecting and reporting data on child fatalities from maltreatment."
