Neurosurgery at the State University of New York at Buffalo

We treated five patients with auricular deformities (microtia in microform and group IIB or III constricted ears) using the following procedure: nearly all of the contralateral conchal cartilage was resected, grafted, and sutured to supplement a cartilaginous deficit and to keep the supporting frame of conchal cartilage expanded by the double banner flap method. After this, a soft tissue deficit was reconstructed by our newly developed method of covering the defect with a triangular flap superior to the auricle by making a skin incision and a rhomboid flap anterior to the auricle. So far, we have obtained satisfactory results using this one-stage procedure.     

School psychology at the University of Texas at Austin.

Describes the development of a university school psychology (SP) program, which began in 1962 as a component of a counseling psychology program. In 1965, the author became director of the SP program. Objectives were to have a leadership role in the field of SP, facilitate both school- and non-school-based career opportunities for nontraditionally educated and trained school psychologists, contribute to the upgrading of doctoral SP, and push for more extensive institutionalization of doctoral SP in public schools. The curriculum has come to encompass more eclectic theoretical foundations. Three reasons are noted for why the program has been successful: its attraction of outstanding students and preparation of graduates for leadership roles, departmental support and breadth, and financial support from the National Institute of Mental Health.

Aggradation at Bridges

Aggradation at bridges causes the bridge waterway opening to be reduced, possibly resulting in upstream flooding and increased contraction scour. Aggradation results when the sediment load supplied to a reach of river from upstream exceeds its capacity to transport sediment. Solutions to aggradational problems at bridges are often complex and expensive. Solutions include increasing sediment transport through the bridge by modifying the channel, constructing an upstream sediment trap, redesigning the bridge, dredging, and treating the cause of the aggradation. At many bridges, aggradation problems can be severe. As an example, aggradation at a bridge in northern Pennsylvania is described. The benefits, disadvantages, and costs for various possible solutions to the example problem are compared and the most cost-effective solution is presented.
