Conflicto familia-trabajo, autoeficacia y cansancio emocional: un análisis de los efectos longitudinales
2015
A partir del modelo revisado Demandas-Recursos Laborales (2008) este artículo pone a prueba dos objetivos: primero, analizar la relación entre el conflicto trabajo-familia y el agotamiento emocional a través del tiempo y, segundo, identificar el papel de la autoeficacia profesional en esta relación. Se trata deun estudio longitudinal con dos recogidas de datos separados por un año en una muestra de militaresespañoles (n = 242). Se ponen a prueba tres modelos sobre la relación longitudinal entre el conflicto trabajo-familia y el cansancio emocional: el modelo causal normal, el modelo causal reverso y el modelo causal recíproco. A su vez, para probar el papel de la eficacia profesional en la …
Sentimientos y teoría de la acción
2001
En el presente trabajo sostenemos que la concepción de la intencionalidad en la teoría de la acción más ampliamente aceptada en la actualidad hace difícil una comprensión adecuada del papel de las emociones en la génesis e interpretación de la acción. La asimilación de las emociones a actitudes intencionales descuida lo que cabría llamar su contenido emocional y pasa por alto importantes diferencias entre su contenido intencional y el de las actitudes intencionales paradigmáticas, como creencias, deseos e intenciones. Sugerimos, sobre esta base, que las relaciones externas y causales deberían tener un lugar más destacado en la comprensión y explicación de las acciones humanas. In this paper…
Explicit Granger causality in kernel Hilbert spaces
2020
Granger causality (GC) is undoubtedly the most widely used method to infer cause-effect relations from observational time series. Several nonlinear alternatives to GC have been proposed based on kernel methods. We generalize kernel Granger causality by considering the variables cross-relations explicitly in Hilbert spaces. The framework is shown to generalize the linear and kernel GC methods, and comes with tighter bounds of performance based on Rademacher complexity. We successfully evaluate its performance in standard dynamical systems, as well as to identify the arrow of time in coupled R\"ossler systems, and is exploited to disclose the El Ni\~no-Southern Oscillation (ENSO) phenomenon f…
A New Multiblock PLS Based Method to Estimate Causal Models: Application to the Post-Consumption Behavior in Tourism
2009
This study presents a new algorithm for estimating causal models based on multiblock PLS method. This new algorithm is tested in a particular post-consumption behavior with the aim of validating a complex system of relations between antecedents of value, perceived value, satisfaction and loyalty. The results are compared with the classical LVPLS method: both methods support the proposed structural relations, but the explained variance is slightly higher with the new algorithm.
Reports of the AAAI 2019 Spring Symposium Series
2019
Applications of machine learning combined with AI algorithms have propelled unprecedented economic disruptions across diverse fields in industry, military, medicine, finance, and others. With the forecast for even larger impacts, the present economic impact of machine learning is estimated in the trillions of dollars. But as autonomous machines become ubiquitous, recent problems have surfaced. Early on, and again in 2018, Judea Pearl warned AI scientists they must "build machines that make sense of what goes on in their environment," a warning still unheeded that may impede future development. For example, self-driving vehicles often rely on sparse data; self-driving cars have already been …
Assessment of Cardiorespiratory Interactions During Spontaneous and Controlled Breathing: Linear Parametric Analysis
2022
In this work, we perform a linear parametric analysis of cardiorespiratory interactions in bivariate time series of heart period (HP) and respiration (RESP) measured in 19 healthy subjects during spontaneous breathing and controlled breathing at varying breathing frequency. The analysis is carried out computing measures of the total and causal interaction between HP and RESP variability in both time and frequency domains (low- and high-frequency, LF and HF). Results highlight strong cardiorespiratory interactions in the time domain and within the HF band that are not affected by the paced breathing condition. Interactions in the LF band are weaker and prevalent along the direction from HP t…
Quantifying High-Order Interactions in Cardiovascular and Cerebrovascular Networks
2022
We present a method to analyze the dynamics of physiological networks beyond the framework of pairwise interactions. Our method defines the so-called O-information rate (OIR) as a measure of the higher-order interaction among several physiological variables. The OIR measure is computed from the vector autoregressive representation of multiple time series, and is applied to the network formed by heart period, systolic and diastolic arterial pressure, respiration and cerebral blood flow variability series measured in healthy subjects at rest and after head-up tilt. Our results document that cardiovascular, cerebrovascular and respiratory interactions are highly redundant, and that redundancy …
RESPONSABILITA' INDIRETTA E OGGETTIVA
2012
La frode alla legge nel diritto interno e l'uniformazione europea della disciplina dei contratti
2010
Il lavoro si è proposto di individuare una serie di questioni che il tema, per così dire «classico», della «frode alla legge» pone anche nella prospettiva del diritto privato europeo. Dopo aver tentato di raccogliere spazi e frammenti di arresti per estrapolarne un quadro organico, ci si è così trovati a dover trattare una serie di tematiche che alludono a una omogeneità di argomenti (quelli concernenti l’autonomia privata) che seguono, in concreto, itinerari tutt’altro che omogenei. Il che ha reso difficile il tentativo di delineare una sintesi il più possibile completa dei temi trattati. L’esperienza diacronica del concetto di frode ha reso necessaria una ricostruzione storico-comparatist…
Travisamenti pretori in tema di esonero dalla responsabilità contrattuale tra causalità e vicinanza della prova
2020
La nota censura la pronuncia in commento a causa della scelta di addossare la prova della causalità materiale al creditore anche nell'ambito delle obbligazioni di facere non professionale, con ciò facendo segnare la piena equiparazione sul piano della causalità della responsabilità contrattuale alla responsabilità aquiliana. The note censures the judgment in question due to the choice of placing proof of material causation on the creditor also in the context of the obligations of non-professional facere, thereby marking the full equation in terms of causality of contractual liability with aquilian liability.
