ECONF C960625:STC118,1996 We review models of electroweak symmetry breaking due to new strong
interactions at the TeV energy scale and discuss the prospects for their
experimental tests. We emphasize ...the direct observation of the new interactions
through high-energy scattering of vector bosons. We also discuss indirect
probes of the new interactions and exotic particles predicted by specific
theoretical models. Working group summary report from the Snowmass `96 summer
study, to appear in the proceedings.

Objective: Residency training programs in all areas of medicine are required to identify core competencies expected of all graduates and develop methods to assess and ensure attainment of these ...competencies. To assist with this process for residency programs in child and adolescent psychiatry, the Work Group on Training and Education of the American Academy of Child and Adolescent Psychiatry has developed several principles of the assessment process and compiled a variety of assessment methodologies for use in assessing competency. The principles of assessment include 1) residents should share responsibility for assessment; 2) assessment should be an open, ongoing and predictable process; 3) a wide range of evaluators should be utilized in the process; 4) residents should demonstrate competency in a variety of formats; 5) the goal is for 100% of residents to achieve core competencies. Methods: Sample methods of assessment are provided in the report with special attention to how the method could be used in child and adolescent psychiatry. Conclusion: A multi-method, multi-evaluator for process of assessment is recommended.

The decays B{sup 0}{yields}D{sup *+}D{sup *-}, B{sup 0}{yields}D{sup *{+-}}D{sup {+-}} and B{sup 0}{yields}D{sup +}D{sup -} are studied in 9.7x10{sup 6} {upsilon}(4S){yields}BB(bar sign) decays ...accumulated with the CLEO detector. We determine B(B{sup 0}{yields}D{sup *+}D{sup *-})=(9.9{sub -3.3}{sup +4.2}stat{+-}1.2syst)x10{sup -4} and limit B(B{sup 0}{yields}D{sup *{+-}}D{sup {+-}})<6.3x10{sup -4} and B(B{sup 0}{yields}D{sup +}D{sup -})<9.4x10{sup -4} at 90% confidence level (C.L.). We also perform the first angular analysis of the B{sup 0}{yields}D{sup *+}D{sup *-} decay and determine that the CP-even fraction of the final state is greater than 0.11 at 90% C.L. Future measurements of the time dependence of these decays may be useful for the investigation of CP violation in neutral B meson decays. (c) 2000 The American Physical Society.
