Diferencias entre empleabilidad, inseguridad laboral y salud en trabajadores y desempleados
2018
ResumenEl desempleo y la inseguridad laboral tienen efectos negativos sobre la salud, aunque la empleabilidad podría mediar dichos efectos. El presente artículo tiene como objetivo analizar las posibles diferencias entre trabajadores y desempleados en empleabilidad y variables de salud psicosocial, así como explorar el papel de la empleabilidad y la inseguridad laboral en la salud psicosocial. Para esto, se utilizó metodología cuasiexperimental, donde se administraron una serie de cuestionarios que evaluaban empleabilidad e inseguridad laboral a 97 trabajadores (35 desempleados y 62 en activo), junto a otras variables psicosociales y de salud. Los resultados muestran que la empleabilidad es…
Drivers of CO2 emissions in the former Soviet Union: A country level IPAT analysis from 1990 to 2010
2013
There are a small number of countries that have managed to decrease emissions over the last two decades e most of them emerged from the FSU (former Soviet Union ). CO2 emissions for these countries combined have decreased by 35% between 1990 and 2010, while global emissions increased by 44%. Most studies investigate the FSU as a single block ignoring the significant and persistent diversity among countries in the region. This study is the first providing detailed country by country analyses determining factors for changes in post-Soviet republics by applying a disaggregated version of the commonly used (IPAT) index decomposition analysis including energy intensity, affluence industrializati…
2017
Aim of the study was the development and validation of the psychometric properties of a six-item bi-factorial instrument for the assessment of social support (emotional and tangible support) with a population-based sample. A cross-sectional data set of N = 15,010 participants enrolled in the Gutenberg Health Study (GHS) in 2007–2012 was divided in two sub-samples. The GHS is a population-based, prospective, observational single-center cohort study in the Rhein-Main-Region in western Mid-Germany. The first sub-sample was used for scale development by performing an exploratory factor analysis. In order to test construct validity, confirmatory factor analyses were run to compare the extracted …
Comparison of non-Markovianity criteria in a qubit system under random external fields
2013
We give the map representing the evolution of a qubit under the action of non-dissipative random external fields. From this map we construct the corresponding master equation that in turn allows us to phenomenologically introduce population damping of the qubit system. We then compare, in this system, the time-regions when non-Markovianity is present on the basis of different criteria both for the non-dissipative and dissipative case. We show that the adopted criteria agree both in the non-dissipative case and in the presence of population damping.
Methodology, Sources and New Evidence
2018
This chapter presents the methodology used to construct the new estimates of regional GDP in Spain, breaking down the territory into NUTS3 and NUTS2 regions (provinces and autonomous communities respectively) and dividing sectors homogeneously into five production areas: agriculture, mining, manufacturing and public utilities, construction and services. Taken as a whole in combination with data on regional population, this information provides a picture of regional inequality in per-capita income in Spain over the long term, starting from the early stages of modern economic growth. This new quantitative evidence enables to point out some of the stylized facts observed in the regional distri…
Experiences of perinatal women and public healthcare providers in a community affected by the great east Japan earthquake and tsunami: Concerns that …
2020
Abstract Particular support needs of perinatal women in a disaster have been difficult to grasp through preexisting quantitative epidemiological studies. This study aimed to extract concerns that must be considered for perinatal women's mental healthcare in postdisaster settings based on lessons from the Great East Japan Earthquake. Narrative messages regarding protective and risk factors for mothers' mental health from a representative population of mothers who had given birth and all official maternal caregivers, in a coastal town devastated by the catastrophe were subjected to qualitative analyses. Eight concerns were extracted as specific support needs: (1) improve information pathways,…

Generalized curved beam on elastic foundation solved by Transfer Matrix Method
2011
A solution of space curved bars with generalized Winkler soil found by means of Transfer Matrix Method is presented. Distributed, concentrated loads and imposed strains are applied to the beam as well as rigid or elastic boundaries are considered at the ends. The proposed approach gives the analytical and numerical exact solution for circular beams and rings, loaded in the plane or perpendicular to it. A well-approximated solution can be found for general space curved bars with complex geometry. Elastic foundation is characterized by six parameters of stiffness in different directions: three for rectilinear springs and three for rotational springs. The beam has axial, shear, bending and tor…
Bounds on plastic strains for elastic plastic structures in plastic shakedown conditions
2007
The problem related to the computation of bounds on plastic deformations for structures in plastic shakedown condition (alternating plasticity) is studied. In particular, reference is made to structures discretized by finite elements constituted by elastic perfectly plastic material and subjected to a special combination of fixed and cyclic loads. The load history is known during the steady-state phase, but it is unknown during the previous transient phase; so, as a consequence, it is not possible to know the complete elastic plastic structural response. The interest is therefore focused on the computation of bounds on suitable measures of the plastic strain which characterizes just the fir…
