La organización del trabajo por proyectos: La fábrica de la precariedad laboral

2019

The project-based organization, considered as a radical reorganization of work around one or more simultaneous projects, is nowadays widespread in large companies and public administrations. According to the managerial way of thinking, this system would be virtuous: by giving more autonomy to the employees in the act of production and by developing their skills through mobility and interdisciplinarity of work teams, it would be able to arouse their full commitment. This study confirms in some way how this opinion has been imposed, but at the expense of precarious working conditions, increasing the dedication of employees and silencing any form of criticism. The research is based on a review…

Knowledge organization for modelling workflows in Taverna environment

2014

Today Workflow Management Systems (WFMS), like Taverna and Kepler, have a very important place in the everyday work of the scientist. These tools support the access to computational resources and act as interface for building complex data processing chains. The next step is to support decisions of the researcher on autonomously developing workflow parts guided by requirements of the scientist while she/he is working on the high-level goal of the experiment. To this aim, it is necessary an ontology to store the knowledge related to the experiments and tools used, and to make this knowledge available not only to the scientist, but also to a suitable artificial intelligent system. In this pape…

Programas de intervención con hombres penados por violencia de género: el enfoque motivacional como aproximación para mejorar su eficacia

2020

La violencia de género es un problema de salud pública de proporciones epidémicas con serias consecuencias para la salud física y psicológica de las víctimas, sus hijos y la sociedad en su conjunto. Una de las aproximaciones para responder a esta problemática son los programas de intervención con maltratadores. Los meta-análisis que se han llevado a cabo para evaluar la eficacia de estos programas han mostrado tamaños del efecto pequeños. Debido a ello, se han propuesto nuevos acercamientos como vía para incrementar su eficacia, entre los que destacan las estrategias motivacionales. El objetivo de la presente tesis doctoral fue analizar el efecto de la inclusión de estrategias motivacionale…

Współdziałanie nauczycieli i rodziców w eliminowaniu trudności wychowawczych

2013

Trudności wychowawcze z uczniami klas młodszych stanowią jeden z najważniejszych problemów współczesnej edukacji Zagadnienie to jest bardzo istotne, gdyż coraz więcej dzieci sprawia rożnego rodzaju problemy, z którymi nie mogą poradzie sobie zarowno rodzice, jak i nauczyciele W artykule zostaną przedstawione wyniki badan na temat współpracy nauczycieli z rodzicami wraz z propozycjami eliminowania negatywnych zachowań u uczniów Ważne jest przy tym, aby nauczyciele wspólnie z rodzicami podejmowali pracę z dziećmi sprawiającymi trudności wychowawcze

Wolność wyboru rodzaju działalności naukowej a przesłanki ustawowe uzyskania tytułu naukowego profesora

2022

Niniejsze opracowanie dotyczy analizy ustawowych kryteriów dla przyznania tytułu profesora, w ramach tak zwanej Konstytucji dla Nauki. W treści artykułu postawiono nacisk na swobodę wyboru formy aktywności naukowej dla kandydata do tytułu profesora, jaka wynika z treści ustawy. Ustawodawca użył złożonej normy prawnej dla ustalenia kryteriów dla kandydata do tytułu profesora. Może ona budzić wątpliwości zarówno praktyczne, jak i teoretyczne

Search for Light Dark Matter Interactions Enhanced by the Migdal Effect or Bremsstrahlung in XENON1T.

2019

Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c2, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c2 by looking for electronic recoils induced by the Migdal effect and bremsstrahlung us…

Piston driven yaw mechanism

2014

Masteroppgave i mekatronikk MAS 500 Universitetet i Agder 2014 The current thesis presents a piston driven yaw mechanism for wind turbines. Traditionally the yaw mechanismhas been one of the mayor contributors to down time and repair has been costly. The proposed designaims to improve the reliability of the yaw mechanism by reducing the point loads and by using hydrauliccylinders instead electrical motors to generate torque. In addition the design is modular allowing the mechanismto be disassembled and components to be replaced without the requirement of complicated or costlymachinery. The current thesis presents an analysis of the state of the art and discusses concepts which maysolve some…

The science case of the FRS Ion Catcher for FAIR Phase-0

2019

The FRS Ion Catcher at GSI enables precision experiments with thermalized projectile and fission fragments. At the same time it serves as a test facility for the Low-Energy Branch of the Super-FRS at FAIR. The FRS Ion Catcher has been commissioned and its performance has been characterized in five experiments with 238U and 124Xe projectile and fission fragments produced at energies in the range from 300 to 1000 MeV/u. High and almost element-independent efficiencies for the thermalization of short-lived nuclides produced at relativistic energies have been obtained. High-accuracy mass measurements of more than 30 projectile and fission fragments have been performed with a multiple-reflection…

An IPMSM torque/weight and torque/moment of inertia ratio optimization

2014

In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…
