The 5 x 5 plan for asthma control: the green route to asthma control

Apart from medication to control asthmatic inflammation, the education of patients and parents is the most important therapeutic step in achieving asthma control and normal life. This is a critical, but sadly often neglected, activity. It can be stated with certainty that an asthmatic who does not know the information outlined in this paper will never be free of asthma symptoms. Education is important at every visit, and is not time consuming or difficult to perform. This plan is easy to remember and use.Keywords: asthma, GINA, Global Initiative for Asthma, inflammation, allergen

Political Orientation and the Decision to Major in Economics: Some Preliminary Observations

Studies find that students major in economics for a variety of reasons. None, however, have examined students' political orientations as a possible factor in their choice of majors. Economics, as compared to other social sciences, tends to produce conservative policy recommendations. This pilot study explores whether more conservative students are attracted to economics. Our study found that men with conservative political leanings are more likely to major in economics and that male students in economics are more conservative than female students. Political orientation, however, does not appear to be a significant factor in the choice of a major for women.

Ultra- and Hyper-compact HII regions at 20 GHz

We present radio and infrared observations of 4 hyper-compact HII regions and 4 ultra-compact HII regions in the southern Galactic plane. These objects were selected from a blind survey for UCHII regions using data from two new radio surveys of the southern sky; the Australia Telescope 20 GHz survey (AT20G) and the 2nd epoch Molonglo Galactic Plane Survey (MGPS-2) at 843 MHz. To our knowledge, this is the first blind radio survey for hyper- and ultra-compact HII regions. We have followed up these sources with the Australia Telescope Compact Array to obtain H70-alpha recombination line measurements, higher resolution images at 20 GHz and flux density measurements at 30, 40 and 95 GHz. From this we have determined sizes and recombination line temperatures as well as modeling the spectral energy distributions to determine emission measures. We have classified the sources as hyper-compact or ultra-compact on the basis of their physical parameters, in comparison with benchmark parameters from the literature. Several of these bright, compact sources are potential calibrators for the Low Frequency Instrument (30-70 GHz) and the 100-GHz channel of the High Frequency Instrument of the Planck satellite mission. They may also be useful as calibrators for the Australia Telescope Compact Array, which lacks good non-variable primary flux calibrators at higher frequencies and in the Galactic plane region. Our spectral energy distributions allow the flux densities within the Planck bands to be determined, although our high frequency observations show that several sources have excess emission at 95 GHz (3 mm) that can not be explained by current models.Comment: 13 pages, 7 figures, accepted for publication in MNRA
