    The molecular gas in the supernova remnant IC443

    Although a few highly perturbed regions characterized by gas motions with velocities larger than 20 km/s have been discovered during the last several years in the supernova remnant (SNR) IC 443, the nature of these perturbed clumps and their relationship to the quiescent molecular gas near the SNR remains unknown. In part, this is due to a lack of large-scale, high angular resolution observations. Therefore, a systematic survey of this SNR in the CO (J=1 yields 0) line has been conducted, covering a roughly 50' x 50' region spaced by 2'. The observations were made with the 14 m telescope of the Five College Radio Astronomy Observatory (FCRAO), which has a resolution of 45" and a single sideband receiver temperature of 200 K at 2.6 mm wavelength. Five new clumps were discovered, bringing the total number of known perturbed regions to eight. To study the physical structure of these clumps in more detail, more complete maps of the clumps have been made in both the CO(J=1 yields 0) and (J=2 yields 1) transitions with the FCRAO telescope. These maps show that the extent of perturbed gas in a typical clump is several arcmin, or a few pc at a distance of 1.5 kpc

    An exploratory study of the role of emotional intelligence and self-efficacy on service quality and adherence in a weight loss setting

    By invoking social cognition theory, this study examines customer competencies that influence service quality perceptions and adherence. Specifically, the study investigates the role of self-efficacy (SE) and emotional intelligence (EI) on perceived quality and adherence. SE and EI are proposed to moderate the relative strength of the relationship between perceived technical and functional quality and adherence. These variables are also proposed to directly influence adherence behavior. Qualitative data were obtained from in-depth interviews with 20 customers on a pharmacy meal replacement program (the “Tony Ferguson Weightloss Program”). Participants were purposely recruited from different urban and regional areas in Australia. The findings suggest that SE and EI moderate the relative strength of quality perceptions. The results also support a direct link between these sociocognitive variables and adherence. By tailoring service delivery interventions to customers displaying different sociocognitive profiles, health organizations could benefit from increased perceptions of quality that could positively influence adherence behavior

    4-Benzoyl-4-methyl-1, 2-epoxypentane, An attempted synthesis

    The object of this research was to prepare first the simplest homologue of the epoxy-ketone considered by Russell to have been his product. If this homologue, 4-benzoyl-4-methyl-1,2-epoxypentane, could be prepared and caused to form a cyclic derivative of the type given by 1,4-diketones with 2,4-dinitrophenylhydrazone, the organic chemist would be given a new approach to substituted 1,2-diazines as well as a previously unreported reaction of the epoxide grouping. If this reaction could be made to occur, other epoxides of this series would be prepared and treated in the same manner. It was decided that the shortest route to 4-benzoyl-4-methyl-1,2-epoxypentane would be the direct condensation of epichlorohydrin with isobutyrophenone. There was also the possibility of condensing isobutyrophenone with allyl halides to produce 4-benzoyl-4-methyl-1-pentene. This could then be converted to the halohydrin followed by treatment with base to form the epoxide, or it could be treated with a peracid to form the epoxide directly --Introduction, pages 2-3

    Reducing Disparities in Smoking for Adults with Mental Illness: Are U.S. Tobacco Prevention Policies Effective?

    Get PDF
    One in five people in the U.S. are estimated to experience “any mental illness” (AMI); however this group represents an estimated 40% of the annual, adult cigarette consumption in the U.S. Tobacco prevention policies have been successful at reducing smoking prevalence among the U.S. population as a whole, however it is unclear whether these efforts have had significant impact on tobacco use rates among individuals with AMI. The three papers that comprise this project combined longitudinal, nationally-representative data and online behavioral experiments from U.S. adults to compare demand for cigarettes among adult smokers with and without AMI. Taken together, our findings imply that adults with AMI have the potential to have more difficulty reducing combustible tobacco use under certain conditions than adults without these symptoms, making it imperative that this population remain a high priority for investigators seeking to reduce a significant disparity in use rates and combustible tobacco-related health consequences
