Roadway incidents involving motorized vehicles accounted for 24% of fatal occupational injuries in the United States during 2013 and were the leading cause of fatal injuries among workers.* In 2013, workers' compensation costs for serious, nonfatal injuries among work-related roadway incidents involving motorized land vehicles were estimated at $2.96 billion.(†) Seat belt use is a proven method...

This paper investigates the effects of mandatory seat belt laws on driver behavior and traffic fatalities. Using a unique panel data set on seat belt usage in all U.S. jurisdictions, we analyze how such laws, by influencing seat belt use, affect the incidence of traffic fatalities. Allowing for the endogeneity of seat belt usage, we find that such usage decreases overall traffic fatalities. The...

INTRODUCTION Obesity has been shown to increase the risks of some types of injury in crashes. One way in which obesity may increase injury risk is by changing the routing of the belt relative to the underlying skeletal structures. METHODS Belt fit was measured in a laboratory study of 54 men and women, 48 percent of whom were obese, defined by body mass index (BMI) of 30 kg/m(2) or greater. T...

BACKGROUND The relevance of climatic events as causative factors for cholera epidemics is well known. However, examinations of the involvement of climatic factors in intracontinental disease distribution are still absent. OBJECTIVES The spreading of cholera epidemics may be related to the dominant wind direction over land. METHODS We examined the geographic diffusion of three cholera outbre...

background: seat belts have been proven as one of the most successful means of preventing or reducing injuries to occupants of cars during an accident. this paper examines the reasons behind the non-compliance of the seat belt law in malaysia and suggests possible measures to get the percentage of seat belt usage up higher. methods: various databases of articles were searched for seat belt usag...

Visual input provides vital information for helping us modify our walking pattern. For example, artificial optic flow can drive changes in step length during locomotion and may also be useful for augmenting locomotor training for individuals with gait asymmetries. Here we asked whether optic flow could modify the acquisition of a symmetric walking pattern during split-belt treadmill adaptation....

Many Rust-Belt cities have seen almost half their populations move from inside the city borders to the surrounding suburbs and elsewhere since the 1970s. As populations shifted, neighborhoods changed—in their average income, educational profi le, and housing prices. But the shift did not happen in every neighborhood at the same rate. Recent research has uncovered some of the patterns characteri...
