Additional file 2 of Subjective well-being’s alterations as risk factors for major depressive disorder during the perimenopause onset: an analytical cross-sectional study amongst Mexican women residing in Guadalajara, Jalisco
No full textAdditional file 2: Qualitative dataset. Excel (.csv) file with the 252 BIARE results, grouped into qualitative categories. For the 14 CC’s indicators (Columns B to C; T to AE) and 11 EC’s statements (Columns D to N), there are two category codes: 1 means score values from 0 to 6; and 0 the score values from 7 to 10. Meanwhile, by subtracting the positive mood indicators whith their counterparts (Columns O to X from Additional File 1) we classified the AC’s scores (Columns O to S) into two codes: 1 means score values from − 10 to – 1; 0 means results from 0 to 10. The last column reflects the presence (1) or absence (0) of MDD by means of the BDI-II
The H states studied in the reaction and evidence of extremely correlated character of the H ground state
No full textThe extremely neutron-rich system H was studied in the direct H transfer reaction with a 26 MeV secondary He beam. The measured missing mass spectrum shows a resonant state in H at MeV relative to the H+ threshold. There is also some evidence of a resonant state at MeV which is a realistic candidate for the H ground state (g.s.). The population cross section of the presumably -wave states in the energy range from 4 to 8 MeV is b/sr in the angular range . The obtained missing mass spectrum is free of the H events below 3.5 MeV (b/sr in the angular range ), which indicates that the value of 4.5 MeV is the lower limit of the possible H g.s. location. The obtained results confirm that the decay mechanism of the H g.s. (located at 2.2 MeV above the H+ threshold) is the ``true'' (or simultaneous) emission. The resonance energy profiles and the momentum distributions of the sequential HH(g.s.)+H+ decay fragments were analyzed by the theoretically-updated direct four-body-decay and sequential-emission mechanisms. The measured momentum distributions of the H fragments in the H rest frame indicate a very strong ``dineutron-type'' correlations in the H ground state decay
Radon mitigation during the installation of the CUORE 0 nu beta beta decay detector
No full textCUORE - the Cryogenic Underground Observatory for Rare Events - is an experiment searching for the neutrinoless double-beta (0νββ) decay of 130Te with an array of 988 TeO2 crystals operated as bolometers at ∼10 mK in a large dilution refrigerator. With this detector, we aim for a 130Te 0νββ decay half-life sensitivity of 9×1025 y with 5 y of live time, and a background index of 10-2 counts/keV/kg/y. Making an effort to maintain radiopurity by minimizing the bolometers' exposure to radon gas during their installation in the cryostat, we perform all operations inside a dedicated cleanroom environment with a controlled radon-reduced atmosphere. In this paper, we discuss the design and performance of the CUORE Radon Abatement System and cleanroom, as well as a system to monitor the radon level in real time
Study of proton and deuteron pickup reactions (d,3He), (d,4He) with 8He and 10Be radioactive beams at ACCULINNA-2 fragment separator
No full textThe extremely neutron-rich systems 7H, 6H were studied in the 2H(8He, 3He)7H and 2H(8He, 4He)6H proton and deuteron pickup reactions with a 26 AMeV secondary 8He beam produced at the new ACCULINNA-2 fragment separator. In addition, the same proton and deuteron pickup reactions were generated using the 42 AMeV 10Be beam, and the population of low-lying 9Li and 8Li states was measured in reactions 2H(10Be,3He)9Li and 2H(10Be,4He)8Li, respectively. The latter were used as reference measurements in order to check the setup calibration over the excitation energy of 7,6H and to determine the real experimental energy resolution which was compared with Monte Carlo calculations. The corresponding results obtained for the superheavy hydrogen systems 7H, 6H are presented and discussed. Typical excitation spectra of the 9Li and 8Li nuclei are also shown
Relación del Bienestar Subjetivo de los trabajadores con su Compromiso hacia la organización
No full textAbstract
The organizational employee commitment conceptualizes the intention to remain in the work place, as the identification of corporative values and the moral sense of engagement due to the benefits received, under the name of organizational commitment (OC). Previous studies show that OC positively affects the subjective well-being of workers (SW), understood as the cognitive and affective assessment that people make of their own life satisfaction. Other studies state that the effect goes from SW to OC. This study aimed to specify the direction of this relationship, for this purpose OC and SW instruments were applied to 230 workers of a higher education public organization in Mexico. Using structural equation models, the hypothesis of relations in both directions between the two variables was contrasted with a third hypothesis of reciprocal relationships between both. The best model was identified as having positive and reciprocal relationships between CO and BS (Chi2 = 65,627, df = 18, p = 0.000, RMR = .074, RMSEA = .111 [CI 90%= .083, .141]; GFI = .931; CFI = .915). It is concluded that increases in OC strengthen SW, and positive relationship between both variables is reciprocal. The implications of the findings on workers´ relationships in the work place are discussed.El compromiso organizacional (CO) de los trabajadores es entendido como una actitud o estado de ánimo que deriva en comportamientos como la intención de permanecer en la organización, la identificación con sus valores y la percepción de tener una deuda moral con la misma por los beneficios recibidos. Estudios previos muestran que el CO impacta positivamente el bienestar subjetivo de los trabajadores (BS), entendido este último como la evaluación cognitiva y afectiva que hacen las personas de la satisfacción sobre su propia vida. Otros estudios afirman que es el BS el que predice el CO. El objetivo del presente estudio fue especificar la dirección de esta relación, para lo cual se aplicó el Instrumento de Compromiso Organizacional para evaluar el CO y el módulo básico del Bienestar Autorreportado (BIARE) para evaluar el BS, a 230 trabajadores de una organización educativa pública de nivel superior en México. Mediante modelos de ecuaciones estructurales se contrastaron las hipótesis de relaciones en uno y otro sentido entre ambas variables con una tercera hipótesis con relaciones recíprocas entre ambas. Se identificó como mejor modelo el que presenta relaciones recíprocas y positivas entre el CO y el BS (Ji2=65.627; gl=18; p=0.000; RMR=.074; RMSEA=.111 [IC 90%= .083, .141]; GFI=.931; CFI=.915). Se concluye que un incremento en el CO genera un incremento en el BS de los trabajadores, y la relación positiva entre ambas variables es recíproca. Se discuten las implicaciones de estos resultados para la relación de los trabajadores con su contexto laboral
The H states studied in the reaction and evidence of extremely correlated character of the H ground state
Get PDFThe extremely neutron-rich system H was studied in the direct
H transfer reaction with a
MeV secondary He beam. The measured missing mass spectrum shows a broad
bump at MeV above the H+ decay threshold. This bump can be
interpreted as a broad resonant state in H at MeV. The
population cross section of such a presumably -wave state (or may be few
overlapping states) in the energy range from 4 to 8 MeV is
b/sr in the angular
range . The obtained missing mass
spectrum is practically free of the H events below 3.5 MeV
( b/sr in the same angular
range). The steep rise of the H missing mass spectrum at MeV
allows to derive the lower limit for the possible resonant-state energy in
H to be MeV. According to the paring energy estimates, such a
MeV resonance is a realistic candidate for the H ground state
(g.s.). The obtained results confirm that the decay mechanism of the H
g.s.\ (located at 2.2 MeV above the H+ threshold) is the "true" (or
simultaneous) emission. The resonance energy profiles and the momentum
distributions of fragments of the sequential HH(g.s.)+H+ decay were analyzed by the
theoretically-updated direct four-body-decay and sequential-emission
mechanisms. The measured momentum distributions of the H fragments in the
H rest frame indicate very strong "dineutron-type" correlations in the
H ground state decay.Comment: 16 pages, 19 figure
