Protecting Kids, Reducing Crime, Saving Money: Preventing Child Abuse and Neglect in Washington by Supporting Intensive Home Visiting.

The 126 police chiefs,sheriffs,district attorneys,other law enforcement leaders and violence survivors who are members of FIGHT CRIME:INVEST IN KIDS WASHINGTON, and the over 3,000 members of FIGHT CRIME:INVEST IN KIDS nationwide,have taken a hard-nosed look at what works-and what does not work-to cut crime and violence.Extensive evidence shows that children who suffered abuse or neglect are more likely to grow up to commit crimes.Solid research shows that nearly half of all abuse and neglect in high-risk families can now be prevented by programs that also prepare children to succeed in school. Preventing abuse and neglect will directly protect children and save lives. Sharply reducing abuse and neglect will also save the public hundreds of millions of dollars in Washington while greatly reducing the number of children growing up to be violent criminals

Statistical distinguishability between unitary operations

The problem of distinguishing two unitary transformations, or quantum gates, is analyzed and a function reflecting their statistical distinguishability is found. Given two unitary operations, $U_1$ and $U_2$, it is proved that there always exists a finite number $N$ such that $U_1^{\otimes N}$ and $U_2^{\otimes N}$ are perfectly distinguishable, although they were not in the single-copy case. This result can be extended to any finite set of unitary transformations. Finally, a fidelity for one-qubit gates, which satisfies many useful properties from the point of view of quantum information theory, is presented.Comment: 6 pages, REVTEX. The perfect distinguishability result is extended to any finite set of gate

Maximum Likelihood Estimation in Gaussian Chain Graph Models under the Alternative Markov Property

The AMP Markov property is a recently proposed alternative Markov property for chain graphs. In the case of continuous variables with a joint multivariate Gaussian distribution, it is the AMP rather than the earlier introduced LWF Markov property that is coherent with data-generation by natural block-recursive regressions. In this paper, we show that maximum likelihood estimates in Gaussian AMP chain graph models can be obtained by combining generalized least squares and iterative proportional fitting to an iterative algorithm. In an appendix, we give useful convergence results for iterative partial maximization algorithms that apply in particular to the described algorithm.Comment: 15 pages, article will appear in Scandinavian Journal of Statistic
