The psychological effects of exercise

Thousands of businesses in the United States have implemented programs to promote physical fitness among their employees (Falkenberg, 1987). The programs range from company-paid memberships at private health and fitness clubs to complete work site fitness facilities. These programs have been developed not only to improve and maintain employee health but also to promote psychological well-being and productivity and to reduce absenteeism, insurance claims, and stress. Recent research focusing on the use of employee fitness programs to improve work-related behaviors suggests that these programs may improve absenteeism, job satisfaction, tenure. and health care costs, especially among female employees (Baun, Bernacki, & Tsai, 1986; Bernacki & Baun, 1984; Browne, Russell, Morgan, Optenberg, & Clarke, 1984; Der-Karabetian & Gebharp, 1986; Tsai, Baun, & Bernacki, 1987)

On Properties of the Isoscalar Giant Dipole Resonance

Main properties (strength function, energy-dependent transition density, branching ratios for direct nucleon decay) of the isoscalar giant dipole resonance in several medium-heavy mass spherical nuclei are described within a continuum-RPA approach, taking into account the smearing effect. All model parameters used in the calculations are taken from independent data. Calculation results are compared with available experimental data.Comment: 12 pages, 2 figure

Measurement of the branching fraction of the doubly Cabibbo-suppressed decay D0 →k+π-π0 and search for D0 →k+π-π0π0

Using 2.93 fb-1 of e+e- collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present a measurement of the branching fraction of the doubly Cabibbo-suppressed (DCS) decay D0→K+π-π0 and a search for the DCS decay D0→K+π-π0π0. The branching fraction of D0→K+π-π0 is determined to be [3.13-0.56+0.60(stat)±0.15(syst)]×10-4. No signal is observed for D0→K+π-π0π0, and an upper limit of 3.6×10-4 is set on the branching fraction at the 90% CL. We combine these results with the world-average branching fractions of their counterpart Cabibbo-favored decays to determine the ratios of the DCS over the Cabibbo-favored branching fractions, B(D0→K+π-π0)/B(D0→K-π+π0)=(0.22±0.04)% and B(D0→K+π-π0π0)/B(D0→K-π+π0π0)<br/

The Construction of Conforming-to-shape Truss Lattice Structures via 3D Sphere Packing

Truss lattices are common in a wide variety of engineering applications, due to their high ratio of strength versus relative density. They are used both as the interior support for other structures, and as structures on their own. Using 3D sphere packing, we propose a set of methods for generating truss lattices that fill the interior of B-rep models, polygonal or (trimmed) NURBS based, of arbitrary shape. Once the packing of the spheres has been established, beams between the centers of adjacent spheres are constructed, as spline based B-rep geometry. We also demonstrate additional capabilities of our methods, including connecting the truss lattice to (a shell of) the B-rep model, as well as constructing a tensor-product trivariate volumetric representation of the truss lattice - an important step towards direct compatibility for analysis.RYC-2017-2264

Inviting end-of-life talk in initial CALM therapy sessions: A conversation analytic study

OBJECTIVE: To examine how end-of-life talk is initiated in CALM therapy sessions with advanced cancer patients. METHODS: Conversation analysis was used to systematically examine the sequences where talk about death was raised in the first sessions of ten patients. RESULTS: Open questions about the patients' experiences, feelings or understanding in the context of talk about their troubles, were found to regularly elicit talk concerning end-of-life. These questions were designed in ways that invite patients to discuss troubling aspects of their cancer journey, without making discussion of this topic an interactional requirement. That is, the interactional work required to not engage in such talk is minimised. This choice is provided through the open question design, the degree to which negative feeling descriptors are specified, and the sequential context of the question. CONCLUSION: The analysis shows that therapists provide patients with the opportunity to talk about end-of-life in a way that is supportive of the therapeutic relationship. The readiness of patients to engage in end-of-life talk displays the salience of this topic, as well as the reflective space provided by CALM therapy. PRACTICE IMPLICATIONS: The results provide important insight into the process of CALM therapy, which can be used to guide training

Evaluation of the mean intensity of the P-odd mixing of nuclear compound states

A temperature version of the shell-optical-model approach for describing the low-energy compound-to-compound transitions induced by external single-particle fields is given. The approach is applied to evaluate the mean intensity of the P-odd mixing of nuclear compound states. Unified description for the mixing and electromagnetic transitions allows one to evaluate the mean intensity without the use of free parameters. The valence-mechanism contribution to the mentioned intensity is also evaluated. Calculation results are compared with the data deduced from cross sections of relevant neutron-induced reactions.Comment: LaTeX, 10 page

The gamma-ray telescope Gamma-1

French and Soviet specialists have designed and built the gamma-ray telescope GAMMA-1 to detect cosmic gamma rays above 50 MeV. The sensitive area of the detector is 1400 sq cm, energy resolution is 30% at 300 MeV, and angular resolution 1.2 deg at 300 MeV (and less than 20' arc when a coded aperture mask is used). Results on calibration of the qualification model and Monte-Carlo calculations are presented
