Human resource function strategic role and trade unions: exploring their impact on human resource management practices in Uruguayan firms

2014

Organizations worldwide are confronted with different contextual constraints. Jackson and Schuler [1995, ‘Understanding Human Resource Management in the Context of Organizations and their Environments,' Annual Review of Psychology, 46, 237–264], in their classical review, highlight the importance of the impact of the internal and external organizational context on human resource management (HRM) practices. This paper uses data collected through a survey of firms located in Uruguay, in a context where HR function and trade unions have gone through significant changes, to determine their impact on the adoption of different HRM practices. The authors find that organizations with an HR function…

The euro impact on trade: long run evidence with structural breaks

2012

In this paper we present new evidence on the euro effect on trade. We use a data set containing all bilateral combinations in a panel of 26 OECD countries during the period 1967-2008. From a methodological point of view, we implement a new generation of tests that allow solving some of the problems derived from the non-stationary nature of the data. To this aim we apply panel tests that account for the presence of cross-section dependence as well as discontinuities in the non-stationary panel data. We test for cointegration between the variables using panel cointegration tests, especially the ones proposed by Banerjee and Carrióni- Silvestre (2010). We also efficiently estimate the long-run…

Le parti des travailleurs brésilien : de son émergence à la conquête du Planalto (1979 - 2002)

2016

The Brazilian Workers’ Party (PT) is an outstanding experience of a left-wing mass party. When it was born in 1980, many people wondered about its nature. In 2002, when Lula became the President of Brazil, this question did not deserve the same answer. The PT became bureaucratic, institutional and professional, experiencing a sort of accelerated Social-Democratization. As its starting point, this study takes the specificities of labour movement, trade unionism and the dictatorship (1964-1985) in Brazil. The PT originated in 1979-80 from mass social struggles around “authentic” trade unionists (such as Lula), left-wing Catholics, far-left activists, the left-wing intelligentsia and some “pro…

Estimation of Passenger Car Equivalents for single-lane roundabouts using a microsimulation-based procedure

2017

Calibration of microscopic traffic simulation models for single-lane roundabouts.Use of a meta-analytical estimation of critical and follow up headways.Use of a genetic algorithm-based procedure.Calculation of passenger car equivalents for single-lane roundabouts. Passenger car equivalents for heavy vehicles are required to carry out capacity calculations and perform operational analysis of any road entity (roadway segments or intersections). At single-lane roundabouts, the constraints to the vehicular trajectories imposed by the curvilinear geometric design and the driver's gap acceptance behaviour are expected to produce an impact of the heavy vehicles on the quality of traffic flow diffe…

Psammomatous malignant melanoma arising in an intradermal naevus

2001

Psammomatous malignant melanoma arising in an intradermal naevus Aims: A wide variety of differentiation patterns may be found in malignant melanoma. Schwannian features are unusual, and mostly present in the desmoplastic variant. We report the first description of psammoma bodies in malignant melanoma. Methods and results: A malignant melanoma arose in an intradermal naevus of the scalp in a 51-year-old woman, displaying focal neural-like features in the form of rosette-like pseudo-meissnerian alveolar nests, as well as numerous psammoma bodies grouped in a few areas. Tumour cell immunostaining for S100, HMB45, NKI-C3, and vimentin was detected. In addition, both malignant and benign melan…

La fatigue mentale : marqueurs électrophysiologiques et stratégies de compensation

2021

Mental fatigue is a common phenomenon in modern society, causing an alteration in both cognitive and physical performances. It can lead to an increased risk of accidents, a drop in productivity, and certain disorders such as depression. The objective of this thesis work was to study this phenomenon of mental fatigue by investigating more specifically its electrophysiological markers, and to find compensatory strategies to limit and/or avoid its deleterious effects.The first study identified brain activity modulations during a prolonged modified Stroop task. An increase in theta and alpha waves, as well as a decrease in N100 and P300 amplitude reflecting a decrease in attention were observed…

The transport activity of the human cationic amino acid transporter hCAT-1 is downregulated by activation of protein kinase C

2001

1 The human cationic amino acid transporter hCAT-1 contains several consensus sequences for phosphorylation by protein kinase C (PKC). This study investigates the eAect of PKC activation on hCAT-1-mediated transport. 2 When expressed in Xenopus laevis oocytes, hCAT-1-mediated L-arginine transport was reduced to 44+3% after a 30 min treatment of the oocytes with 100 nM phorbol-12-myristate-13-acetate (PMA). 4a-phorbol-12,13-didecanoate (4a-PDD, 100 nM) had no eAect. 3 In EA.hy926 endothelial cells, maximal inhibition of hCAT-1-mediated L-arginine transport (to 3‐11% of control) was observed after treatment of the cells with 100 nM PMA for 4 h. A 20‐30 h exposure of the cells to 100 nM PMA le…

In vivo activity of pseudoguaianolide sesquiterpene lactones in acute and chronic inflammation.

2000

The pseudoguaianolide sesquiterpene lactones 4-alpha-O-acetyl-pseudoguaian-6beta-olide (1), hymenin (2), ambrosanolide (3), tetraneurin A (4), parthenin (5), hysterin (6) and confertdiolide (7) were evaluated for their ability to affect the inflammation responses induced by different agents. All the compounds showed activity against the 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced mouse ear edema. The ethyl phenylpropiolate (EPP)-induced mouse ear edema was inhibited by compounds 3, 5 and 7. However, when sesquiterpene-lactones were assayed on the arachidonic acid (AA)-induced mouse ear edema, none of them were active. The only sesquiterpene lactone orally active against the paw mouse…
