This study examined the effect of obesity on the use of indwelling urinary catheters among long-term care facility residents and found initial increases in usage by weight category, which declined during the next 12 months.

Virtual teams are increasingly global, creating challenges for communication and coordination due to greater distances, multiple time zones, and cultural differences. A longitudinal research program investigating communication and collaboration in globally distributed engineering design teams is described. Preliminary results illustrate the value of combining quantitative and qualitative source...

BACKGROUND Supervised injection facilities (SIFs) are legally sanctioned environments for people to inject drugs under medical supervision. SIFs currently operate in ten countries, but to date, no SIF has been opened in the USA. In light of increasing overdose mortality in the USA, this study evaluated willingness to use a SIF among youth who report non-medical prescription opioid (NMPO) use. ...

Licit and illicit drug use in pregnant women constitutes a long lasting and serious problem worldwide. Information on long-term effects of maternal drug use on the child is limited. Nationwide registers provide a great potential to study short and long-term consequences for children exposed to licit and illicit drugs during pregnancy. We discuss this potential, with a special emphasis on exposu...

How to select interesting feature sets from data streams is a new and important research topic in which there are three major challenges. First of all, instead of discovering features individually and independently, we are interested in comprehensively selecting a subset of features whose joint importance or weight is the highest. Secondly, we are concerned with the problem of selecting feature...

Much of the text of pen resources such as Wikipedia is written at a college level of readability, thus posing an access barrier to the general public. Reading levels are important when considering wiki approaches for a K-12 OER community, and even more so when developing for minority language schools. In Canada, many students learning in a minority language setting lack the environmental influe...

The syntactic bootstrapping hypothesis suggests that children’s verb learning is guided by the structural cues that the linguistic context provides. However, the onset of syntactic bootstrapping in word learning is not well studied. To investigate the impact of linguistic information on word learning during early stages of language acquisition, we use a computational model of learning syntactic...

BACKGROUND This study is an empirical assessment of the impact of the drug decriminalization policy followed by Portugal in July 2001, on the price of illicit drugs. METHODS The analysis is performed using a difference-in-differences approach and the Synthetic Control Method in order to construct a synthetic control unit from a convex combination of countries. RESULTS The results suggest th...
