OBJECTIVE To investigate outpatient outcome measures of a multi-center, state-wide, universal newborn hearing screening project. DESIGN Eight hospitals participated in a 3-yr, funded project. Each hospital designed its own protocol using common criteria for judging whether an infant passed a hearing screening. Infants were tested in the hospital, and(More)
OBJECTIVE To determine the ages of hearing loss identification, hearing aid fitting, and enrollment in early intervention through a multi-center, state-wide universal newborn hearing screening project. DESIGN Universal newborn hearing screening was conducted at eight hospitals across New York State. All infants who did not bilaterally pass hearing(More)
A benthic index of estuarine condition was constructed for the Virginian Biogeographic Province (from Cape Cod, Massachusetts, to the mouth of Chesapeake Bay, Virginia) with data collected during summers of 1990 through 1993 by the US EPA’s Environmental Monitoring and Assessment Program (EMAP). Forty-eight metrics, based on attributes of the macrobenthos,(More)

We evaluated the education system of the United States from 1870 to 2011 using emergy methods. The system was partitioned into three subsystems (elementary, secondary and college/university education) and the emergy inputs required to support each subsystem were determined for every year over the period of analysis. We calculated the emergy required to(More)
OBJECTIVE To examine the effect of test environment on recording transient-evoked otoacoustic emissions (TEOAE) in neonates. METHODS Thirty-two infants from the newborn nursery (NBN) who passed a screening auditory brainstem response (SABR) test and were at least 34 weeks' postconceptional age were studied. One ear of each newborn was tested using TEOAE(More)
OBJECTIVE To evaluate the feasibility of universal newborn hearing screening by examining inpatient outcome measures from 8 hospitals located in geographically diverse areas of New York State over a 3-yr period. DESIGN Funding was provided by the New York State Department of Health to implement predischarge hearing screening programs in the neonatal(More)
The agricultural and industrial development of small cities is the primary environmental management strategy employed to make full use of extra labor in the rural areas of China. The ecological and economic consequences of this development strategy will affect over 100 million people and change the organization of the Chinese landscape. In this study, we(More)
