Experiences of mindfulness training in living with rheumatic disease: an interpretative phenomenological analysis
This study examined experiences of Mindfulness training for 5 adults living with Rheumatic Disease. Focus group data was used to explore the experience and impact of Mindfulness training in participants aged between 46 and 69 diagnosed with Psoriatic Arthritis, Fibromyalgia or Rheumatoid Arthritis. All participants had completed an 8-week Mindfulness-Based Stress Reduction Programme (MBSR) 6 months prior to the study. Interpretative Phenomenological Analysis produced two themes: ‘responding to pain’ and ‘psychological well-being’. All participants spoke similarly and with enthusiasm, reflecting the strength of the impact of Mindfulness upon the daily lives of these individuals. Methodological limitations are considered along with clinical applications and suggestions for future research. The findings from this study reinforce the outcomes of previous research and indicate that Mindfulness has potential to improve the health and well-being of individuals living with Rheumatic Disease
401(k) Plans and Race
Many data sources show a disparity among racial and ethnic groups regarding participation in and contributions to 401(k) plans. White workers participate at a higher rate and contribute a higher percentage than African American and Hispanic workers. However, few studies have explored whether these differences persist once other factors expected to impact these decisions are taken into consideration. One recent study by Ariel/ Hewitt using client data found lower participation and contributions rates in 401(k) plans for African Americans and Hispanics than for Whites, even after controlling for age, tenure, and earnings.
Nuclear emulsion measurements of the astronauts' radiation exposures on Skylab missions 2, 3, and 4
On the Skylab missions, Ilford G.5 and K.2 emulsions were flown as part of passive dosimeter packs carried by the astronauts on their wrists. Due to the long mission times, latent image fading and track crowing imposed limitations on a quantitative track and grain count analysis. For Skylab 2, the complete proton energy spectrum was determined within reasonable error limits. A combined mission dose equivalent of 2,490 millirems from protons, tissue stars and neutrons was measured on Skylab 2. A stationary emulsion stack, kept in a film vault drawer on the same mission, displayed a highly structured directional distribution of the fluence of low-energy protons (enders) reflecting the local shield distribution. On the 59 and 84-day mission 3 and 4, G.5 emulsions had to be cut on the microtom to 5-7 microns for microscopic examination. Even so, the short track segments in such thin layers precluded a statistically reliable grain count analysis. However, the K.2 emulsions still allowed accurate proton ender counts without special provisions

Nuclear emulsion measurements of the astronauts' radiation exposure on the Apollo-Soyuz mission
On the Apollo-Soyuz mission each astronaut carried one passive dosimeter containing nuclear photographic emulsions, plastic foils, TLD chips, and neutron-activation foils for recording radiation exposure. This report is limited to the presentation of data retrieved from nuclear emulsions. Protons, most of them trapped particles encountered in numerous passes through the South Atlantic Anomaly, contributed by far the largest share to the mission dose. Their linear energy transfer (LET) spectrum was established from track and grain counts in a G.5 emulsion which is used for medium and high energies, and from ender counts in a K.2 emulsion which is used for low energies. The total mission fluence of protons was found to be equivalent to a unidirectional beam of 448,500 square centimeters. The broad spectrum was broken down into small LET intervals, which allowed for the computation of absorbed doses and dose equivalents. The totals are 51 millirad and 74 millirem. Counts of disintegration stars in K.2 emulsion are incomplete at present. While a total of 467 stars were identified, counting their prong numbers is still in progress. It was concluded that the Apollo-Soyuz astronauts' radiation exposure as such did not contain anything out of the ordinary that would seem to require special attention

Coronal sources of the intrastream structure of the solar wind
Short time scale changes in the bulk speed were found not to coincide with X-ray transients near the sub-earth point nor with the number of X-ray bright points within a coronal hole and near the equator. The changes in bulk speed, it is shown, are associated with changes in light areas in a hole which may be associated with the opening or closing of magnetic field lines within the coronal hole. That there is a causal connection between these sudden changes (apperance or disappearance) in light area and sudden changes in the bulk speed of the solar wind is further evidenced by the spatial proximity on the Sun of these changing light regions to the source position of stream lines from Levine's model that connect into the same solar wind streams
