A study of internal medicine residents found that those reporting higher levels of fatigue and distress were more likely to report medical errors. The study suggests that fatigue, sleepiness, burnout, depression, and reduced quality of life are independently associated with an increased risk of future self-perceived major medical errors.
The program aims to develop advanced statistical methodologies for implementing USDA surveys and analyzing survey results. Four focus areas have been identified: multivariate imputation, new design and estimation methodologies, automated editing and imputation methods, and statistical multi-source predictive models.
A new University of Melbourne study found that nearly one in five working women and one in eight working men experience preventable depression caused by job stress. The study estimates that more than 21,000 cases of preventable depression are caused by job stress each year.
A Northwestern University study found that juries give wrong verdicts in at least one out of eight cases, with agreement rates between judges and jurors varying between 77-80%. The study uses statistical analysis to estimate the accuracy of jury verdicts, suggesting that juries may be less accurate than judges in certain cases.
A recent study from Georgetown University reveals that the number of new high-tech visas required by the US economy over the next decade is significantly higher than initially assumed. The report suggests that Congress may be authorizing too many visas, with 630,000 left over after filling all available positions.
A French BSE epidemic is believed to have infected at least 1,200 cattle since 1987, with around 100 animals slaughtered for human consumption in 2000. The risk of BSE entering the food chain from British beef has been reduced, but late-stage infected animals are likely to have been slaughtered for meat.
A study published in Preventive Medicine reveals that smoking is a leading cause of fires and death from fires globally, resulting in an estimated cost of nearly $7 billion in the US and $27.2 billion worldwide. Smoking causes 30% of fire deaths in the US and 10% globally.
A study by Princeton researchers estimates that 8-18 million Americans may identify with more than one race in the 2000 census, several times greater than previous estimates. The vast majority of likely multiple race respondents chose 'White' when faced with the traditional single-response race question.
A new study found that Americans overestimate their lifespan by about a year compared to official statistics. Blacks and men are the most optimistic about their lifespans, while white females predict they will live less than expected.
Researchers use 'Cosmic Triangle' to plot evidence for accelerated universe expansion and high mass density of dark energy. The findings rule out models with low or negative mass density, pointing towards a flat universe dominated by dark energy.
Researchers have found that the Earth's inner core is rotating at a faster rate than its outer layers, with estimates suggesting it rotates four to 12 times slower. The independent rotation is thought to be caused by convection in the molten iron outer core, which produces the Earth's magnetic field.
