Determining the Gamma-Ray Burst Rate as a Function of Redshift
We exploit the 14 gamma-ray bursts (GRBs) with known redshifts z and the 7
GRBs for which there are constraints on z to determine the GRB rate R_{GRB}(z),
using a method based on Bayesian inference. We find that, despite the
qualitative differences between the observed GRB rate and estimates of the SFR
in the universe, current data are consistent with R_{GRB}(z) being proportional
to the SFR.Comment: To appear in Procs. of Gamma-Ray Bursts in the Afterglow Era: 2nd

Monetary benefits of preventing childhood lead poisoning with lead-safe window replacement
Previous estimates of childhood lead poisoning prevention benefits have quantified the present value of some health benefits, but not the costs of lead paint hazard control or the benefits associated with housing and energy markets. Because older housing with lead paint constitutes the main exposure source today in the U.S., we quantify health benefits, costs, market value benefits, energy savings, and net economic benefits of lead-safe window replacement (which includes paint stabilization and other measures). The benefit per resident child from improved lifetime earnings alone is 8,685 in 1940-59 housing (in 2005 dollars). Annual energy savings are 486 per housing unit, with or without young resident children, with an associated increase in housing market value of 14,300 per housing unit, depending on home size and number of windows replaced. Net benefits are 5,629 for each housing unit built before 1940, and 1,629 for each unit built from 1940-1959, depending on home size and number of windows replaced. Lead-safe window replacement in all pre-1960 U.S. housing would yield net benefits of at least $67 billion, which does not include many other benefits. These other benefits, which are shown in this paper, include avoided Attention Deficit Hyperactivity Disorder, other medical costs of childhood lead exposure, avoided special education, and reduced crime and juvenile delinquency in later life. In addition, such a window replacement effort would reduce peak demand for electricity, carbon emissions from power plants, and associated long-term costs of climate change.Lead Poisoning, IQ, Energy Efficiency, Cost Benefit Analysis, Housing, Climate Change
Stress of the Caregiver: Effective Management of Dementia Patients in Hospital and Community Settings
This study explores the management problems among elders with dementia and their medical and family caregivers. Twenty-five patients were interviewed as well as professional health care personnel and a family member. Findings indicated that professional assessment facilitates home caregiving but has little bearing on successful coping by the caregiver. Variability of coping relates to the strategy employed
An Ecological Study of the Lagoons Surrounding the John F. Kennedy Space Center, Brevard County, Florida
The studies reported here are the result of a three year effort to define the major biological, microbiological, chemical and geological characteristics of the water of the Indian River lagoon around the Kennedy Space Center and to determine the movements of those waters within and between the various basins. This work was the result of a jointly funded agreement between the Florida Institute of Technology and John F. Kennedy Space Center, NASA under NASA Grant NGR 10-015-008, dated April 11, 1972. This cost sharing grant was renewed for each of two successive years. Sampling operations were terminated August 31, 1975
Blood ordering practices in the management of ectopic pregnancy at Groote Schuur hospital
The International Society for Burns Injuries (ISBI) has published guidelines for the management of multiple or mass burns casualties, and recommends that 'each country has or should have a disaster planning system that addresses its own particular needs.' The need for a national burns disaster plan integrated with national and provincial disaster planning was discussed at the South African Burns Society Congress in 2009, but there was no real involvement in the disaster planning prior to the 2010 World Cup; the country would have been poorly prepared had there been a burns disaster during the event. This article identifies some of the lessons learnt and strategies derived from major burns disasters and burns disaster planning from other regions. Members of the South African Burns Society are undertaking an audit of burns care in South Africa to investigate the feasibility of a national burns disaster plan. This audit (which is still under way) also aims to identify weaknesses of burns care in South Africa and implement improvements where necessary
