Patients' preferences for pain treatment modalities in a multidisciplinary pain clinic.

44 male and 74 female patients (aged 22–78 yrs) in a multidisciplinary pain clinic rated their preferences for 9 pain treatment modalities: ice, transcutaneous electronic nerve stimulation (TENS), relaxation, group therapy, social work, physical therapy, massage, heat, and lectures. Relaxation, physical therapy, and ice were most liked; TENS, heat, and social work were least liked. Multiple regression analyses indicated that preference for relaxation was the best predictor of decreased pain ratings, while preference for heat was correlated with increased pain ratings. Liking for physical therapy predicted self-ratings at discharge of positive well-being and minor life disruption. Liking for heat predicted self-ratings of major life disruption and nurses' ratings of pain behavior at discharge. Results suggest that treatment regimens should take into account patients' moods and personality styles. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Future increase in harmful algal blooms in the North Sea due to climate change.

In temperate seas such as the North Sea harmful (toxic) algal blooms will probably increase as a result of climate change. This conclusion was reached after investigating the projected effect of climate change for the year 2100 in Dutch coastal waters (4 degrees C temperature rise and increased water column stratification) on the growth rates of six harmful and two non-harmful phytoplankton species. Micro algae form the basis of the marine food chain. However, toxin-producing species may seriously disrupt the food web and lead to fish kills and human intoxication. Two species with estimated doubled growth rates in 2100, F. japonica and C. antiqua, entered Europe via ship's ballast water or shellfish imports. This stresses the need to legally regulate such invasion routes in order to prevent the import of novel species. Future toxic phytoplankton blooms may further devaluate ecosystem deliverables such as fish production or recreational use. This devaluation can be estimated by monetary value assessments that are needed in cost-benefit analyses for policy guidance. The lack of understanding of future climate, ecosystem functioning and its response to climate change calls for a scientific effort to improve our knowledge on present day coastal ecosystem functioning and its resilience.     

The relativistic charged particles identification method based on the goodness-of-fit ωn-criterion

The statistical method of identification of relativistic charged particles by measurements of ionization losses or time-of-flights simultaneously in some detectors of an experimental plant on the basis of the new goodness-of-fit ω_n³-criterion is considered. The method proposed has been used for the secondary particles identification from the high energy -particles fragmentation on target nuclei. The efficiency of the method is excellently illustrated by reliable separation of events (rare events as well), connected with the appearence of 1- and 2-charged particles. The comparison of the ω_n³-method with the traditional methods and with the method based on the ω_n²-criterion shows that the new method outperforms the ω_n²-method and most of the traditional ones in efficiency, but compares unfavourably with the likelihood method in power, however, the former has a number of advantages as compared with the latter.
