«Permanent Education» and «Permanent Learning»: Two different theoretical and practical models

open access: yesRevista Iberoamericana de Educación, 2010
This paper analyzes the evolution of the concept of permanent education; the similarities and differences between the point of view of unesco and the European Union; the evolution of these two different points of view; and its current role in national and international educative policies In the unesco case, there are two premises that condition its ...

A note on dissipativity and permanence of delay difference equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
Summary: We give sufficient conditions on the uniform boundedness and permanence of non-autonomous multiple delay difference equations of the form \[ x_{k+1}=x_k f_k(x_{k-d},\dots,x_{k-1},x_k), \] where \(f_k\colon D \subseteq (0,\infty)^{d+1}\to (0,\infty)\). Moreover, we construct a positively invariant absorbing set of the phase space, which implies

Permanence of brain sex differences and structural plasticity of the adult brain [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Sex differences in brain structure have been widely recognized since the pioneering studies of Raisman and Field (1). For the most part, brain sex differences are thought to arise in perinatal development through the actions of testosterone secreted by the developing testes, and these sex differences are believed to persist in the absence of gonadal ...

ESR1 methylation and ESR1 mutations in circulating tumor cells (CTCs) and paired plasma‐cfDNA of advanced breast cancer patients: A feasibility proof‐of‐concept study

open access: yesMolecular Oncology, EarlyView.
Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...

Interpreting the effects of DNA polymerase variants at the structural level

open access: yesMolecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Precarious and less well paid? Wage differences between permanent and fixed-term contracts across the EU [PDF]

open access: yes, 2015
We analyse wage differences between permanent and fixed-term contracts across the EU using data from the European Structure of Earnings Survey. We find that, after controlling for individual and job characteristics, workers on permanent contracts earn on
