The attributes included were: exercise type; time spent on exercise per day; frequency; transport type; travel time; out-of-pocket costs; reduction in the chance of falling; and improvement in the ability to undertake tasks inside and outside of home.
This correction was published on 18 September 2011: Swedish students have shown a significant fall in reading ability between 2000 and 2009, as reported in "Doubts grow over the success of Sweden's free schools experiment" (News).
In reading such graphs, tests with better discriminatory ability fall in the top left corner of the plot, and non-discriminatory tests fall on a 45° line between the bottom left and top right.
Moreover, regular PA in older individuals contributes to an increase in longevity, a reduction of pain from arthritis, a decrease of risk to falls and fractures, and an increase in the ability to maintain functional independence [ 6].
Articular chondrocytes proliferate in monolayer culture, but the expression of the transcription factor SOX9 falls and the ability of the cells to reform cartilage tissue declines.
Most non-vertebral fractures are associated with falls, and this dependence on falls complicates the ability to predict fractures accurately.
There seems to be difficulties in the ability to identify patients at high risk for falling in hospital settings [ 35].
We did not consider post-fall behaviour, such as the ability to rise after falling [ 20], since preliminary viewing of videos indicated that, for the vast majority of falls in common areas in LTC, residents are assisted by care staff to rise after falling.
In addition, there were no suitable items to discriminate persons whose ability fell into the extreme ability level (ability level between 5 ~ 6 or −4 ~ −6).
Mr Schelling invested his hopes for peace not in arms reductions or fall-out shelters but in preserving the ability to retaliate, for example by putting missiles into submarines.All-out thermonuclear warfare is the kind of game you get to play only once.
