BACKGROUND Safety belt use is 80% nationally, yet only 63% in Massachusetts. Safety belt use among potentially at-risk groups in Boston is unknown. We sought to assess the prevalence and correlates of belt non-use among emergency department (ED) patients in Boston. METHODS A cross-sectional survey with systematic sampling was conducted on non-urgent ED patients age > or = 18. A closed-ended s...

OBJECTIVES Traffic crashes are a leading cause of deaths and injuries in Pakistan. The World Health Organization (WHO) estimates that approximately 30,131 people die in road crashes annually on Pakistani roads (WHO 2013). The use of seat belts can be effective in reducing road crash fatalities in Pakistan but under existing seat belt laws, seat belt use is mandatory only for drivers and is limi...

Front-seat safety belt use in the United States (US) was 80 percent in June, 2004. This rate represents the highest ever for the US, but indicates that there is still a sizable minority of people who do not always use safety belts despite mandatory seat belt laws in all but one state. Changing the behavior of these people will require new and innovative countermeasures. Little research has syst...

OBJECTIVE Injuries sustained in motor vehicle accidents (MVAs) are a major challenge to the Jamaican healthcare system. In November 1999, Jamaica enacted legislation to make seat belt usage in motor vehicles compulsory. The effect of this policy change on seat belt usage is unclear. This study therefore sought to determine the prevalence of seat belt usage and to determine the association betwe...

Nbody simulations are used to examine the consequences of Neptune’s outward migration into the Kuiper Belt, with the simulated endstates being compared rigorously and quantitatively to the observations. These simulations confirm the findings of Chiang et al. (2003), who showed that Neptune’s migration into a previously stirred–up Kuiper Belt can account for the Kuiper Belt Objects (KBOs) known ...

Whereas Poe's passers-by cast glances in all directions which still appeared to be aimless, today's pedestrians are obliged to do so in order to keep abreast of traffic signals. Thus technology has subjected the human sensorium to a complex kind of training. There came a day when a new and urgent need for stimuli was met by the film. In a film, perception in the form of shocks was established a...

Proper seat belt use saves lives; however, the use rate decreased in Korea. This study aimed to measure the magnitude of the preventive effect of seat belt on case-fatality across drivers and passengers. We used the Emergency Department based Injury In-depth Surveillance (EDIIS) database from 17 EDs between 2011 and 2012. All of adult injured patients from road traffic injuries (RTI) in-vehicle...

The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally assumed that the belt formed with far more mass and was later strongly depleted. We show that the present-day asteroid belt is consistent with having formed empty, without any planetesimals between Mars and Jupiter's pre...
