Precarious work and social protection: between flexicurity and social pollution
2019
The chapter explores the possibility of changing the way in which any social and legal system guarantees social protections for the weakest workers. To do so it elaborates a unique functional set for classifying all kind of precariat, which it names the ‘un[der]-protected workers’. The issue of the precariat is held as an imbalance in the flexicurity balance, considered akin to pollution in the social environment: so-called social pollution. The proposed method to counterbalance the lack of security/protection and rebalance flexicurity is a ‘(non-wage) Social Security (virtual or) Fake (Pigouvian) Tax’ (the SSFT). The idea is that this device either forces companies to hire through SERs (wh…
Effect of moisture on elastic and viscoelastic properties of epoxy and epoxy-based carbon fibre reinforced plastic filled with multiwall carbon nanot…
2016
Abstract In this study, we investigated the peculiarities of moisture absorption and moisture-induced effects on the elastic and viscoelastic flexural properties of epoxy resin and carbon fibre reinforced plastic (CFRP) filled with multiwall carbon nanotubes (MWCNTs). Short-term cyclic creep-recovery tests of moistened epoxy and CFRP filled with MWCNTs revealed improvements in creep resistance for both materials. The addition of MWCNTs to the epoxy resin suppressed the moisture absorption by the material, causing a reduction in the diffusion coefficient by 31% and equilibrium moisture content by 15%. The addition of MWCNTs reduced the flexural strength of moistened epoxy and CFRP samples by…
Effect of external basalt layers on durability behaviour of flax reinforced composites
2016
Abstract Aim of this work is to evaluate the influence of external layers of basalt-mat on the durability behaviour of flax reinforced epoxy composites. To this scope, long-term ageing tests were performed on two different laminates in critical environmental conditions. The first laminate, named Flax, was constituted by stacking ten layers of bidirectional flax fabrics. The second one, named Flax–Basalt, was produced by replacing two external flax layers with two layers of basalt mat for each side of the laminate. Both laminates were exposed to salt-fog environmental conditions, according to ASTM B 117 standard, for 60 days. Five samples per laminate were removed from salt-fog spray chamber…
Straightforward Approach for Preparing Durable Antibacterial ZnO Nanoparticle Coatings on Flexible Substrates
2022
Flexible antibacterial materials have gained utmost importance in protection from the distribution of bacteria and viruses due to the exceptional variety of applications. Herein, we demonstrate a readily scalable and rapid single-step approach for producing durable ZnO nanoparticle antibacterial coating on flexible polymer substrates at room temperature. Substrates used are polystyrene, poly(ethylene-co-vinyl acetate) copolymer, poly(methyl methacrylate), polypropylene, high density polyethylene and a commercial acrylate type adhesive tape. The deposition was achieved by a spin-coating process using a slurry of ZnO nanoparticles in toluene. A stable modification layer was obtained when tolu…
El Objetivo de la Flexiseguridad en la Reforma Laboral Española de 2012
2015
En el preámbulo de la Ley 3/2012, de 6 de julio, de medidas urgentes para la reforma del mercado laboral, se establece literalmente que “el objetivo es la flexiseguridad”. Y se añade también que “la reforma propuesta trata de garantizar tanto la flexibilidad de los empresarios en la gestión de los recursos humanos de la empresa como la seguridad de los trabajadores en el empleo y adecuados niveles de protección social”, o que dicha reforma “apuesta por el equilibrio en la regulación de nuestras relaciones de trabajo”. Sin embargo, del análisis de las medidas concretas que contiene la reforma laboral se desprende una clara contradicción con ese objetivo y lo mismo sucede cuando se analizan l…
Del análisis de las experiencias en el Practicum, al cambio curricular en la Formación de Maestros
2002
La presente actividad se apoya en situaciones reales de aula que durante las prácticas se ofrecen a la observación de los estudiantes. Su análisis exige utilizar conocimientos diversos para su comprensión, facilitando la unión de la teoría y la práctica. Consideramos que la formación profesional debe ser un proceso de indagación y experimentación para aprender a enseñar. En ese proceso se establecen continuas interrelaciones entre el marco teórico de referencia y la generación de teorías emergentes desde la práctica que posibilitan la reelaboración del conocimiento. Los resultados de este análisis, formulados en forma de problemas, se convierten en elemento de estudio y se integran en un pr…
Rutinas en ELE: La enseñanza de verbos reflexivos desde una aproximación pragmática
2009
Maria.D.Garcia@uv.es Este trabajo presenta un estudio de aula sobre la enseñanza de verbos reflexivos como elementos lingüísticos para la expresión de rutinas diarias en español como lengua extranjera (ELE) desde un enfoque pragmático. Dicho enfoque aboga por la enseñanza y aprendizaje de lenguas orientado al desarrollo del ‘conocimiento pragmático’ de los aprendices de éstas, a saber, el conocimiento consciente de los recursos lingüísticos de una lengua, y las asunciones lingüísticas y socio-culturales que subyacen al uso de los mismos en diferentes contextos. Los sujetos del estudio mostraron en general resultados más positivos que estudiantes de otros grupos de su mismo nivel. This paper…
Potentials of Togetherness: Beyond Individualism and Community in Nordic Art Education
2013
Historically, art education has focused mainly on individual learning processes. In Nordic countries,' for example, discourses of training the rational individual through skills of objective representation, developing the authentic individual through child-centered education, or stimulating identity-processes through critical pedagogy have dominated over ideas of collectivity, community, and society (llleris, 2002; Kjosavik, 2001; Lindstrom, 2009; Pedersen, 1998; Pohjakallio, 1998). Today, poststructuralist theories of subjectivity and subjectivation are challenging these modernist discourses by proposing more dynamic models of multiple and instable learning selves, always in the making (e.…
Thiopentalkonzentrationsverlauf im Vollblut von schwangeren und nichtschwangeren Patientinnen in den ersten Minuten nach der Injektion
1991
Thiopentone concentrations in blood following injection of the induction solution (Thiopental, 2.5%) may be critical in the context of lethal complications arising during induction of anaesthesia and thereby the toxicological aspects of this drug can become an issue in forensic considerations. The study was designed to find out whether the dose of injected thiopentone may be calculated from blood levels measured in nine pregnant and ten non-pregnant patients. The doses injected ranged from 4-5 mg per kg body weight. The drug was administered as a single bolus dose to the patients undergoing Caesarean section. In the non-pregnant group the first dose of thiopentone was given over 25 s. After…
Control of VOC emissions from a flexographic printing facility using an industrial biotrickling filter.
2011
The study of an industrial unit of biotrickling filter for the treatment of the exhaust gases of a flexographic facility was investigated over a 2-year period with the objective to meet the volatile organic compound (VOC) regulatory emission limits. Increasing the water flow rate from 2 to 40 m3 h−1 improved the performance of the process, meeting the VOC regulation when 40 m3 h−1 were used. An empty bed residence time (EBRT) of 36 s was used when the inlet air temperature was 18.7 °C, and an EBRT as low as 26 s was set when the inlet temperature was 26.8 °C. During this long-term operation, the pressure drop over the column of the bioreactor was completely controlled avoiding clogging prob…
