Latvia. Human Development Report 2010/2011: National identity, Mobility and Capability
2011
The 2010/2011 report was produced under the auspices of the national research programme „National Identity”. The job of the report is to survey the content of individual national belonging in the context of human development. The report particularly focuses on emigration issues, because human development is weakened by a reduction in the size of the country’s population. The fact that people are moving to other countries shows that there is an endless competition among identities, as well as a transformation of those identities. The report also reveals the set of circumstances and techniques (the ability to act) which facilitate links between an individual and a location or region. The firs…
The Greenland shark Somniosus microcephalus—Hemoglobins and ligand-binding properties
2017
A large amount of data is currently available on the adaptive mechanisms of polar bony fish hemoglobins, but structural information on those of cartilaginous species is scarce. This study presents the first characterisation of the hemoglobin system of one of the longest-living vertebrate species (392 +/- 120 years), the Arctic shark Somniosus microcephalus. Three major hemoglobins are found in its red blood cells and are made of two copies of the same a globin combined with two copies of three very similar beta subunits. The three hemoglobins show very similar oxygenation and carbonylation properties, which are unaffected by urea, a very important compound in marine elasmobranch physiology.…
Coexistence of superconductivity and spin-splitting fields in superconductor/ferromagnetic insulator bilayers of arbitrary thickness
2021
Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an important ingredient for numerous superconducting spintronics applications and the realization of Majorana fermions. A crucial parameter that determines the magnitude of the induced spin splitting in FI/S bilayers is the thickness of the S layer d: In very thin samples, the superconductivity is suppressed by the strong magnetism. By contrast, in very thick samples, the spin splitting is absent at distances away from the interface. In this work, we calculate the density of …
Sporta pasākumu organizācijas vietne
2022
Sports ir cilvēka dzīves neatņemama sastāvdaļa. Daudzi sporta veidi prasa noteiktu cilvēku skaitu. Bieži gadās, ka nevaram savākt vajadzīgo cilvēku skaitu. Gadās arī tā, ka trenēties vienam ir vienkārši garlaicīgi. Sporta pasākumu organizācijas vietne ir SPA (Single Page Application) lietotne, kas paredzēta sportistu savienošanai un iepazīstināšanai. Šī lietotne ļauj veidot sporta pasākumus, un lietotāji, savukārt, var tajos piedalīties. Šai lietotnei ir arī karte, kurā var atzīmēt dažāda veida sporta laukumus, piemēram, skeitparku vai tenisa kortu.
Motivations, engagement and adoption of e-WOM in restaurants.
2022
Resumen El objetivo del presente trabajo fue estudiar el efecto que tienen las motivaciones para consultar y escribir e-WOM sobre el compromiso con el e-WOM y la influencia de dicho compromiso en la adopción del e-WOM consultado. Para analizar estas relaciones, se realizó una investigación empírica aplicada en el contexto de los restaurantes. El ámbito geográfico fue Ecuador, con una muestra de 461 consumidores. Se utilizó un modelo de ecuaciones estructurales y se validó la cadena de relaciones. Los resultados confirmaron las relaciones entre estas variables; además, se presentaron implicaciones académicas interesantes para profundizar en el estudio sobre el compromiso con el e-WOM, así co…
La sonrisa del éxito: figuraciones de una subjetividad exigida
2014
El presente artículo analiza cómo se afianza en la escena social la corporalidad del liderazgo. Para ello, aborda imágenes y narrativas que circulan en los entramados simbólicos de la cultura del bienestar, que también se denomina como cultura activa. El cuerpo del liderazgo se ofrece al público mediante estrategias positivas y negativas. Éstas, en la medida que encumbran el estilo de vida activo, demonizan aquellas prácticas que no responden a los valores sanitarios y productivos promulgados por el ethos empresarial emergente. Se concluye que la encarnación de una subjetividad emprendedora se impone paulatinamente como parámetro de integración de un individuo en los diagramas económicos y …
Economic Support during the COVID Crisis. Quantitative Easing and Lending Support Schemes in the UK
2021
Abstract We investigate how UK bank business lending responded to the simultaneous use of quantitative easing, leverage ratio capital requirements, and government COVID lending support schemes. We find no evidence that the Brexit wave increased lending to nonfinancial businesses, compared to the previous waves, except for QE-banks subject to the UK leverage ratio, suggesting that the ratio incentivised QE-banks to lend to businesses. The government schemes helped expand lending especially to SMEs post the COVID wave, indicating that complementing QE with other credit easing programmes can reinforce its impact on lending to the real economy. During COVID-stress, changes to the UK leverage ra…
A Model for High-Cycle Fatigue in Polycrystals
2018
A grain-scale formulation for high-cycle fatigue inter-granular degradation in polycrystalline aggregates is presented. The aggregate is represented through Voronoi tessellations and the mechanics of individual bulk grains is modelled using a boundary integral formulation. The inter-granular interfaces degrade under the action of cyclic tractions and they are represented using cohesive laws embodying a local irreversible damage parameter that evolves according to high-cycle continuum damage laws. The consistence between cyclic and static damage, which plays an important role in the redistribution of inter-granular tractions upon cyclic degradation, is assessed at each fatigue solution jump,…
Hybrid Equilibrium Finite Element Formulation for Cohesive Crack Propagation
2019
Equilibrium elements have been developed in hybrid formulation with independent equilibrated stress fields on each element. Traction equilibrium condition, at sides between adjacent elements and at sides of free boundary, is enforced by use of independent displacement laws at each side, assumed as Lagrangian parameters. The displacement degrees of freedom belongs to the element side, where an extrinsic interface can be embedded. The embedded interface is defined by the same stress fields of the hybrid equilibrium element and it does not require any additional degrees of freedom. The extrinsic interface is developed in the consistent thermodynamic framework of damage mechanics with internal …
Virtual Element Method: Micro-Mechanics Applications
2019
In this contribution we present an application of the lowest order Virtual Element Method (VEM) to the problem of material computational homogenization. Material homogenization allows retrieving material properties through suitable volume averaging procedures, starting from a detailed representation of the micro-constituents of the considered material. The representation of such microstructure constitutes a remarkable effort in terms of data/mesh preparation, especially when there is not evident microstructural regularity. For such a reason, computational micromechanics may represent a challenging benchmark for showing the potential of VEM. In this contribution, polycrystalline materials ar…
