Union representation and prevention of occupational risks during the crisis: impact and limits

2019

La investigación que presentamos estudia el impacto de la intervención sindical en materia de salud laboral, en lo que se refiere tanto a la gestión preventiva y creación de una cultura participativa como en los procesos de vigilancia y control de las condiciones de trabajo. A tal efecto, se han consultado las principales encuestas nacionales e internacionales sobre gestión de riesgos laborales en las empresas, analizando los datos más relevantes en base a modelos de regresión logística y lineal, lo que ha permitido constatar que la representación sindical de los trabajadores en la empresa (generalista y especializada) correlaciona positivamente con el desarrollo de las principales dimensio…

Emerging Economies Faced With The Downside Of Financial Globalization: Hedges And Way Outs

2009

The underlining assumption of this paper is that developing countries are in a fragile state nowadays. Economically, they have been seriously harmed by the 2008 crisis1 but this is not the end of the story: the future still has pitfalls in which these economies might get trapped, due to their enhanced vulnerability to exogenous shocks generated by financial globalization. Ideologically, the recent events have triggered a serious backlash against capitalism, particularly the Anglo-Saxon template. Getting an insight into the causes and implications of global economic crises is therefore critical for policy-makers in emerging economies. History might be a good adviser in this respect. Lessons …

Empirical Study on the Relationship between the Cross-Correlation among Stocks and the Stocks' Volatility Clustering

2013

In this paper we discuss univariate and multivariate statistical properties of volatility with the aim of understanding how these two aspects are interrelated. Specifically, we focus on the relationship between the cross-correlation among stock's volatilities and the volatility clustering. Volatility clustering is related to the memory property of the volatility time-series and therefore to its predictability. Our results show that there exists a relationship between the level of predictability of any volatility time-series and the amount of its inter-dependence with other assets. In all considered cases, the more the asset is linked to other assets, the more its volatility keeps memory of …

F-type lectin from the sea bass (Dicentrarchus labrax): purification, cDNA cloning, tissue expression and localization, and opsonic activity.

2009

Recently described biochemical and structural aspects of fucose-binding lectins from the European eel (Anguilla anguilla) and striped bass (Morone saxatilis) led to the identification of a novel lectin family ("F-type" lectins) characterized by a unique sequence motif and a characteristic structural fold. The F-type fold is shared not only with other members of this lectin family, but also with apparently unrelated proteins ranging from prokaryotes to vertebrates. Here we describe the purification, biochemical and molecular properties, and the opsonic activity of an F-type lectin (DlFBL) isolated from sea bass (Dicentrarchus labrax) serum. DlFBL exhibits two tandemly arranged carbohydrate-r…

Role of dioxygenase α-DOX2 and SA in basal response and in hexanoic acid-induced resistance of tomato (Solanum lycopersicum) plants against Botrytis …

2015

Resistance of tomato (Solanum Lycopersicum) to the fungal pathogen Botrytis cinerea requires complex interplay between hormonal signalling. In this study, we explored the involvement of new oxylipins in the tomato basal and induced response to this necrotroph through the functional analysis of the tomato α-dioxygenase2 (α-DOX2)-deficient mutant divaricata. We also investigated the role of SA in the defence response against this necrotrophic fungus using SA-deficient tomato nahG plants. The plants lacking dioxigenase α-DOX2, which catalyses oxylipins production from fatty acids, were more susceptible to Botrytis, and hexanoic acid-induced resistance (Hx-IR) was impaired; hence α-DOX2 is requ…

Absence of the endo-beta-1,4-glucanases Cel1 and Cel2 reduces susceptibility to Botrytis cinerea in tomato.

2007

Cel1 and Cel2 are members of the tomato (Solanum lycopersicum Mill) endo-beta-1,4-glucanase (EGase) family that may play a role in fruit ripening and organ abscission. This work demonstrates that Cel1 protein is present in other vegetative tissues and accumulates during leaf development. We recently reported the downregulation of both the Cel1 mRNA and protein upon fungal infection, suggesting the involvement of EGases in plant-pathogen interactions. This hypothesis was confirmed by assessing the resistance to Botrytis cinerea infection of transgenic plants expressing both genes in an antisense orientation (Anti-Cel1, Anti-Cel2 and Anti-Cel1-Cel2). The Anti-Cel1-Cel2 plants showed enhanced …

Water level regulation in winter triggers fouling of fishing nets by the diatom Aulacoseira islandica in a boreal lake

2015

Water level regulation related to hydroelectric power production and flood prevention is an important hydro-morphological pressure on many watercourses around the world. Fouling of fishing nets in autumn during the open water period and in winter under the ice is a common phenomenon in large Finnish lakes where the water level is regulated. This fouling of fishing nets can sometimes be so extensive that fishing has to be stopped. Based on the practical experiences of fishermen, the main cause for the under-ice fouling has been proposed to be the winter draw-down of water causing low water level and stronger currents in lakes, but no conclusive relationship between fouling and water level re…

Characteristics of regular gamblers in Italy: The role of control and emotion regulation

2016

Objective: the main purpose of this study is to investigate the emotional and temperamental characteristics associated with gambling in Italy and to compare different groups of people on the basis of their risk of gambling: low-risk gamblers, problem gamblers, and pathological gamblers. Particularly, we examined the possible discriminant functions of perception of control, locus of control (whether internal or chance-based; that is, devoted to fate), and emotion-regulation strategies (cognitive reappraisal and expressive suppression). Method: a total of 251 adult regular gamblers (142 males and 109 females) recruited from different betting and bingo halls completed self-report questionnaire…

Gene expression in TGFbeta-induced epithelial cell differentiation in a three-dimensional intestinal epithelial cell differentiation model

2006

Abstract Background The TGFβ1-induced signal transduction processes involved in growth and differentiation are only partly known. The three-dimensional epithelial differentiation model, in which T84 epithelial cells are induced to differentiate either with TGFβ1 or IMR-90 mesenchymal cell-secreted soluble factors, is previously shown to model epithelial cell differentiation seen in intestine. That model has not been used for large scale gene expression studies, such as microarray method. Therefore the gene expression changes were studied in undifferentiated and differentiated three-dimensional T84 cultures with cDNA microarray method in order to study the molecular changes and find new play…
