Seat-belt use still low in Kuwait: self-reported driving behaviours among adult drivers

Kuwait mandated seat-belt use by drivers in 1976 and by front seat passengers in 1994. The study objectives were to identify and estimate current factors associated with seat-belt use and levels of potentially unsafe driving behaviours in Kuwait. In 2010, 741 adults were surveyed regarding driving habits and history. Only 41.6% of drivers reported always using a seat belt. Front seat passenger belt use was more common (30.5%) than rear seat belt use (6.5%). Distracted driving behaviours were common, including mobile phone use (‘always’ or ‘almost always’: 51.1%) and texting/SMS (32.4%). Logistic regression indicated that drivers who were young (18–19 years), male, Kuwaiti nationals or non-Kuwaiti Arabs, drove over the speed limit, had traffic violation tickets or >1 car crashes in the last year, were less likely to use seat belts. Targeted initiatives to increase public awareness and to enforce car-safety legislation, including use of seat belts, are necessary to decrease the health burden of car crashes in Kuwait.     

Signalling,Disclosure And The Implications Of Financial Structure For Uk Corporate R&D ∗

This paper investigates the impact of R&D disclosure and finance variables on the level of R&D expenditures. The question addressed is: what is the impact of changes in disclosure requirements on the relationship between R&D expenditure and the financing of firms? The question is motivated by the possible signalling role that elective disclosure may have had prior to changes in accounting practices to ensure R&D disclosure.

The existence of sampling designs with preassigned inclusion probabilities

Summary The question of the existence of a sampling design realizing given preassigned inclusion probabilities is treated. The question can be fully answered in the case of inclusion probabilities of first order. If the inclusion probabilities of second order are given it is shown why necessary and sufficient conditions for the existence of a corresponding sampling design can be derived only in very special cases.
