MCNP6 simulation of light and medium nuclei fragmentation at intermediate energies

Fragmentation reactions induced on light and medium nuclei by protons and light nuclei of energies around 1 GeV/nucleon and below are studied with the Los Alamos transport code MCNP6 and with its CEM03.03 and LAQGSM03.03 event generators. CEM and LAQGSM assume that intermediate-energy fragmentation reactions on light nuclei occur generally in two stages. The first stage is the intranuclear cascade (INC), followed by the second, Fermi breakup disintegration of light excited residual nuclei produced after the INC. CEM and LAQGSM account also for coalescence of light fragments (complex particles) up to 4He from energetic nucleons emitted during INC. We investigate the validity and performance of MCNP6, CEM, and LAQGSM in simulating fragmentation reactions at intermediate energies and discuss possible ways of further improving these codesComment: 6 pages, 6 figures, proc. 12th Int.

Sense of Humor, Stress, and Burnout in Medical Social Workers

This quantitative study used survey research methodology to explore the relationship befween sense of humor, stress, and burnout in medical social workers. The hypothesis of this study is that a sense of humor will decrease stress, which in turn will descrease burnout for social workers. This study surveyed 75 medical social workers in the State of Minnesota on their use of humor and their current stress and burnout level. The study used the Sense of Humor Rating Scale, the Job Stress Survey, and the Maslach Burnout Inventory as the measures to quantify the variables. The study found that stress is negatively correlated with personal accomplishment and sense of humor is positively correlated with depersonalization. These findings have implications in policy and practice by assisting social service supervisors with identifying sense of humor, stress, and burnout in their employees and creating ways to combat the negative aspects of stress and burnout
