Algo más que el adiós al marxismo. El XXVIII Congreso del PSOE y el derecho de autodeterminación
2021
El XXVIII Congreso del Partido Socialista Obrero Español, celebrado en mayo de 1979, ha sido recordado por la célebre renuncia de Felipe González a la Secretaría General. El PSOE se había reafirmado como marxista y González acababa de perder el debate nominalista sobre la definición del partido. Aquel impacto emocional y mediático permitió ocultar tras los fuegos de artificio otros debates de mayor trascendencia práctica que también se dieron cita en aquel encuentro. Entre ellos, el que tenía que ver con su modelo de política autonómica. Desde 1979 estaba en juego cómo iba a construirse el Estado de las Autonomías, y el PSOE tenía la oportunidad de establecer en la resolución sobre autonomí…
Aspects concerning the manifestation of the students’ emotional intelligence
2010
Abstract In this study, we were proposed to investigate aspects concerning the manifestation of the students’ emotional intelligence, namely the extent to which the adolescents possess a series of capacities proper to emotional intelligence. Wayne Leon Payne defines emotional intelligence as being the ability which implies a creative relation with states of anxiety, pain and desire. Emotion depends on the way a person analyzes and evaluates a certain situation. In order to determine the emotional intelligence quotient, it was used the Emotional Intelligence Test for adults, in the version adapted by M. Rocco from R. Bar-On and D. Goleman. The personality dimensions were determined using the…
State Space-Vector Model of Linear Induction Motors Including Iron Losses: Part II: Model Identification and Results
2018
This is the second part of a paper, divided into two parts, dealing with the definition of a space-vector dynamic model of the linear Induction motor (LIM) taking into consideration both the dynamic end-effects and the iron losses as well as the off-line identification of its parameters. The first part has treated the theoretical framework of the model. This second part is devoted to the description of an identification technique which has been suitably developed for the estimation of the parameters of the LIM dynamic model accounting for both the dynamic end-effects and iron losses, described in the first part of the paper. Such an identification technique is strictly related to the state …
Stability of social support during school transitions: Associations with truancy and not completing upper secondary education in normative time
2022
Not completing upper secondary education is often presignaled by truancy from school. Student-perceived social support from family, peers, and teachers can prevent truancy and the risk of not completing education. However, prior studies have not focused on the stability of social support across school transitions. This longitudinal study of 1901 Finnish students examined the extent to which social support was stable or specific to primary, lower secondary, and upper secondary schools. Moreover, we examined whether support was associated with not completing upper secondary education in normative time and whether truancy mediated the relationship between support and not completing education. …
Asymmetric synthesis of chloroisothreonine derivatives via syn-stereoselective Mannich-type additions across N-sulfinyl-α- chloroimines
2014
Mannich-type reactions of O-Boc glycolic esters across chiral N-sulfinyl-α-chloroaldimines resulted in the efficient and syn-stereoselective synthesis of new γ-chloro-α-hydroxy-β-amino esters (dr > 99:1). The α-coordinating ability of the chlorine atom was of great importance for the diastereoselectivity of the Mannich-type reaction and overruled the chelation of the sulfinyl oxygen with the lithium ion of the incoming E-enolate in the transition state model. These novel chloroisothreonine derivatives proved to be excellent building blocks in asymmetric synthesis of novel syn-β,γ-aziridino-α-hydroxy esters and biologically relevant trans-oxazolidinone carboxylic esters.
Unfolding dynamics of small peptides biased by constant mechanical forces
2018
We show how multi-ensemble Markov state models can be combined with constant-force equilibrium simulations. Besides obtaining the unfolding/folding rates, Markov state models allow gaining detailed insights into the folding dynamics and pathways through identifying folding intermediates and misfolded structures. For two specific peptides, we demonstrate that the end-to-end distance is an insufficient reaction coordinate. This problem is alleviated through constructing models with multiple collective variables, for which we employ the time-lagged independent component analysis requiring only minimal prior knowledge. Our results show that combining Markov state models with constant-force simu…
A weighted combined effect measure for the analysis of a composite time-to-first-event endpoint with components of different clinical relevance
2018
Composite endpoints combine several events within a single variable, which increases the number of expected events and is thereby meant to increase the power. However, the interpretation of results can be difficult as the observed effect for the composite does not necessarily reflect the effects for the components, which may be of different magnitude or even point in adverse directions. Moreover, in clinical applications, the event types are often of different clinical relevance, which also complicates the interpretation of the composite effect. The common effect measure for composite endpoints is the all-cause hazard ratio, which gives equal weight to all events irrespective of their type …
Emotional user experience: Traits, events, and states☆
2015
Emotional experience has become an important topic in human-technology interaction research and design. Nevertheless, such research and design often lacks a proper explanatory basis and methodologically robust operationalisation. In this article, a conceptualisation of emotional user experience is formulated based on the appraisal theory of emotion, where the goal congruence of the interaction events and the task-independent individual traits are thought to underlie the user's emotional response. A laboratory study with N=50 participants conducting ordinary computer tasks is reported. The results suggest that subjective emotional experience depends on a number of factors relating to individ…
Bayesian analysis of a disability model for lung cancer survival
2016
Bayesian reasoning, survival analysis and multi-state models are used to assess survival times for Stage IV non-small-cell lung cancer patients and the evolution of the disease over time. Bayesian estimation is done using minimum informative priors for the Weibull regression survival model, leading to an automatic inferential procedure. Markov chain Monte Carlo methods have been used for approximating posterior distributions and the Bayesian information criterion has been considered for covariate selection. In particular, the posterior distribution of the transition probabilities, resulting from the multi-state model, constitutes a very interesting tool which could be useful to help oncolog…
State Space-Vector Model of Linear Induction Motors including End-Effects and Iron Losses Part I: Theoretical Analysis
2020
This is the first part of the article, divided into two parts, dealing with the definition of a space-vector dynamic model of the linear induction motor (LIM) taking into consideration both the dynamic end-effects and the iron losses and its offline identification. This first part specifically treats the theoretical formulation of this model, which has been expressed in a state form, so to be, in perspective, suitably adopted for developing novel nonlinear control techniques, nonlinear observers as well as electrical losses minimization techniques. Besides the formulation of the dynamic model in space-vector state form, a steady-state analysis is proposed, highlighting the combined effects …
