Using data from the National Survey of Child and AdolescentWell-Being, this study examines differences between kinship and foster placements for infants placed in out-of-home care prior to their first birthday. The differences examined include developmental status at time of placement, differences in the home and neighborhood environments, and the duration of time in placement. Participants included 457 infants placed in either kinship or foster care and their caregivers. Findings suggest that infants placed with kin had fewer developmental concerns 2 to 6 months after the initial Child Protective Services investigation and spent significantly less time in placement. The quality of foster and kinship homes and neighborhoods also differed: Foster homes were generally of better quality and located in safer neighborhoods. Overall, for both kin and foster care, the data suggest that even after passage of the Adoption and Safe Families Act of 1997 (ASFA, Public Law 105-89), infants remain in care for a long time: Approximately one third of infants are still in out-of-home care 3 years after the initial investigation.

This is a paper written to celebrate the 70th birthday of our dear colleague Gaetano Vilasi where we collect some recent results about a couple of maximally superintegrable systems. Both the classical and the quantum version will be considered, and the corresponding solution techniques will be illustrated: namely, the spectrum generating algebra (SGA) for the classical systems and the shape invariance potentials approach (SIP) for the quantum case.

April 20,1909 is generally recog-nized as the birthday of the GeodeticSurvey of Canada, but as far back as1883 attempts to perform geodeticwork in Canada occurred. That yearthe Department of Public Worksbegan precise levelling operationsfrom Rouses Point, Quebec, on theCanada-U.S. border, following theRichelieu River to Sorel on the St.Lawrence River. The purpose of thesurvey was to provide vertical controlfor harbour and river improvements.

We are here today to celebrate the 100th birthday of ASCAP, the American Society of Composers, Authors and Publishers. Birthdays, of course, are an occasion not only for celebration, but also for both reflection and anticipation. As I will explain further, and as I've recently said elsewhere, I think the time has come for Congress to consider how the law might better serve the music marketplace in the digital era. But to understand how we got to where we are today, I will take my cue from Rodgers and Hammerstein's The Sound of Music and "start at the very beginning."~1

21 May 2011 would have marked the 90th birthday of Andrei Dmitrievich Sakharov, a towering 20th-century figure inscience and human thought, whose ideas, research contribu-tions, and life example exerted enormous influence on the history of the second half of the 20th century and, in particu-lar, on the history of Russia. Whether as a scientist or a private person (including his public activities and exceptional attitude to human personality), he always displayed creativity and a freedom of spirit, thought, and action. Sakharov's life and creative work make him a model scientist and citizen for many and undoubtedly provide a legacy for the development of science and society in the 21st century. In this paper, some of Sakhar- ov's key ideas and achievements relating to his KB-11 period are exemplified, and how they influence present day research and technology, notably as employed for affording national secur-ity, is examined.
