    The goal of this research was to determine a model safety and health baccalaureate curriculum. A secondary target was to ascertain if safety and health practitioners and safety and health educators would concur on course offerings. To simplify this study effort, a search of literature was conducted on the Occupational Safety and Health field. There were no in-depth studies of this type for such a general population; therefore no instrument was available for this study. The perusal of literature indicated that most such studies had been conducted using a more specific target group of subjects. That is, faculties or former students of a particular university, one was completed on only certified safety professionals (CSP), or members of the National Safety Managers Society (NSMS) and the like. This study included most geographical areas of the United States of America and thus faculties and former students from many universities. First, it was necessary to determine the competency required for a successful career in Occupational Safety and Health. Second, devise a survey instrument to collect the competency information to function well in his area and essential to the development of a curricula questionnaire. Directories used to select expert subjects to serve as judges for this research included the American Society of Safety Engineers (ASSE), American Industrial Hygiene Association (AIHA), National Safety Council, Business and Industry Division (NSC/B&I), and the World Safety Organisation (WSO). Since the Delphi technique was being used, a pilot study was employed to collect information from a selected group of practitioners and educators. This information served as the basis for creating a survey instrument that was mailed to 489 health and safety practitioners and educators. A total of 355 or 72 per cent of the surveys were returned. Eighteen surveys were undelivered for various reasons, with a total of 337 usable surveys, of this population list responding to the survey ranking the importance of the courses. The data from the returned surveys were analyzed by several different methods suggesting: (I) There was a preference for certain core, elective and preparatory courses. (2) There were some significant differences of the responding safety practitioners and safety educators. (3) There was no evidence of non-respondent bias for the total group; however, considering only the safety practitioners there was some evidence of regional bias. These analyses facilitated the recommendations that certain course offerings be required for: (1) a core curricula, (2) particular preparatory courses and (3) a choice from several electives course listings

    Welcome to Colorado College’s seventh State of the Rockies Report Card. Building upon a strong start in 2004 and continuing each year since, the Rockies Project this year provides a fresh look, through thoughtful analysis, at a fundamental challenge to this beautiful but fragile region: maintaining the Rockies’ key roles in the nation’s food supply and vibrant agriculture. This Report Card and the companion series of 2009- 10 monthly State of the Rockies Food and Agriculture campus speakers are significant outreach activities of Colorado College: Vision 2010, an agenda to strengthen our college and our engagement in the region

    The Effects of Deformation on Isovector Electromagnetic and Weak Transition Strengths

    The summed strength for transitions from the ground state of 12C^{12}C via the operators st,t,rYt,r[Ys]λt\vec{s}t, \vec{\ell}t, rY't, r[Y's]^{\lambda}t and r[Y]λtr[Y'\ell]^{\lambda}t are calculated using the ΔN=0\Delta N = 0 rotational model. If we choose the z component of the isospin operator tzt_{z}, the above operators are relevant to electromagnetic transitions; if we choose t+t_{+} they are relevant to weak transitions such as neutrino capture. In going from the spherical limit to the asymptotic (oblate) limit the strength for the operator st\vec{s} t decreases steadily to zero; the strength for the operator τ\vec{\ell}\tau (scissors mode) increases by a factor of three. For the last three operators - isovector dipole, spin dipole and orbital dipole (including the twist mode) it is shown that the summed strength is independant of deformation. The main difference in the behavior is that for the first two operators we have in-shell transitions whereas for the last three operators the transitions are out of shell.Comment: 14 pages, late

    Neutrino induced transitions between the ground states of the A=12 triad

    Neutrino induced reactions on 12^{12}C, an ingredient of liquid scintillators, have been studied in several experiments. We show that for currently available neutrino energies, EνE_{\nu} \le 300 MeV, calculated exclusive cross sections 12^{12}Cgs(ν,l)_{gs}(\nu,l)12^{12}Ngs_{gs} for both muon and electron neutrinos are essentially model independent, provided the calculations simultaneously describe the rates of several other reactions involving the same states or their isobar analogs. The calculations agree well with the measured cross sections, which can be therefore used to check the normalization of the incident neutrino spectrum and the efficiency of the detector.Comment: 9 pages REVTEX, 2 postscript figures, text and figures available at http://www.krl.caltech.edu/preprints/MAP.htm

    Muon capture on nuclei with N > Z, random phase approximation, and in-medium renormalization of the axial-vector coupling constant

    Get PDF
    We use the random phase approximation to describe the muon capture rate on 44{}^{44}Ca,48{}^{48}Ca, 56{}^{56}Fe, 90{}^{90}Zr, and 208{}^{208}Pb. With 40{}^{40}Ca as a test case, we show that the Continuum Random Phase Approximation (CRPA) and the standard RPA give essentially equivalent descriptions of the muon capture process. Using the standard RPA with the free nucleon weak form factors we reproduce the experimental total capture rates on these nuclei quite well. Confirming our previous CRPA result for the N=ZN = Z nuclei, we find that the calculated rates would be significantly lower than the data if the in-medium quenching of the axial-vector coupling constant were employed.Comment: submitted to Phys.
