Are Spanish SMEs good places to work?
2012
PurposeThis paper aims to perform a descriptive analysis of the current degree of development and application of work‐life balance policies in Spanish SMEs, examining the differences that arise due to ownership structure (family owned business versus non‐family owned business) and presenting an in‐depth analysis of the variables that influence managers' attitudes towards work‐life balance policies.Design/methodology/approachStructured interviews with SME managers were performed.FindingsThe presence of those polices is small, although the situation differs depending on the type of policy. Differences in ownership structure do not imply significantly different behavior with regard to the intr…
Robots, labor markets, and universal basic income
2020
Automation is a big concern in modern societies in view of its widespread impact on many socioeconomic issues including income, jobs, and productivity. While previous studies have concentrated on determining the effects on jobs and salaries, our aim is to understand how automation affects productivity, and how some policies, such as taxes on robots or universal basic income, moderate or aggravate those effects. To this end, we have designed an experiment where workers make productive effort decisions, and managers can choose between workers and robots to do these tasks. In our baseline treatment, we measure the effort made by workers who may be replaced by robots, and also elicit firm repla…
Apoyo a la autonomía, satisfacción de las necesidades psicológicas y bienestar : invarianza de un modelo estructural en futbolistas y bailarines
2015
La teoría de las necesidades psicológicas básicas (Deci y Ryan, 2000) defiende que en los contextos sociales en los que se apoya la autonomía se promueve el bienestar a través de la satisfacción de las necesidades psicológicas básicas. En base a este marco teórico, el objetivo del presente trabajo fue triple: primero, poner a prueba un modelo en el que se analizaba la secuencia: percepción del apoyo a la autonomía ofrecido por el profesor/entrenador - satisfacción de las necesidades psicológicas básicas - bienestar; segundo, examinar el papel mediador de las necesidades, y tercero, estudiar la invarianza del modelo entre dos poblaciones. Participaron 197 bailarines (Medad = 18,65 ± 3,73) y …
Quantitative comparison of motion history image variants for video-based depression assessment
2017
Abstract Depression is the most prevalent mood disorder and a leading cause of disability worldwide. Automated video-based analyses may afford objective measures to support clinical judgments. In the present paper, categorical depression assessment is addressed by proposing a novel variant of the Motion History Image (MHI) which considers Gabor-inhibited filtered data instead of the original image. Classification results obtained with this method on the AVEC’14 dataset are compared to those derived using (a) an earlier MHI variant, the Landmark Motion History Image (LMHI), and (b) the original MHI. The different motion representations were tested in several combinations of appearance-based …
Psychopharmacology treatment and psychological interventions in irritable bowel syndromel
2013
Irritable bowel syndrome (IBS) accounts for 25% of gastroenterology output practice, making it one of the most common disorders in this practice. Psychological and social factors may affect the development of this chronic disorder. Furthermore, psychiatric symptoms and psychiatric diseases are highly prevalent in this condition, but the approach to treating these is not always straightforward. As emphasized in the biopsychosocial model of IBS, with regard to the modulatory role of stress-related brain-gut interactions and association of the disease with psychological factors and emotional state, it proves useful to encourage psychopharmacological treatments and psychosocial therapies, both …
Factor analyses of multidimensional symptoms in a large group of patients with major depressive disorder, bipolar disorder, schizoaffective disorder …
2020
Abstract Background There is an ongoing discussion about which neurobiological correlates or symptoms separate the major psychoses (i.e. Major Depressive Disorder MDD, Bipolar Disorder BD, and Schizophrenia SZ). Psychopathological factor analyses within one of these disorders have resulted in models including one to five factors. Factor analyses across the major psychoses using a comprehensive set of psychopathological scales in the same patients are lacking. It is further unclear, whether hierarchical or unitarian models better summarize phenomena. Method Patients (n = 1182) who met DSM-IV criteria for MDD, BD, SZ or schizoaffective disorder were assessed with the SANS, SAPS, HAMA, HAM-D, …
The potential use of biomarkers as an adjunctive tool for staging bipolar disorder
2009
Recent data show that biomarkers differ in early and late-stage bipolar disorder (BD). Here we propose a model of staging for bipolar disorder that emphasizes the potential use of biomarkers for differentiating early and late-stage BD patients in the inter-episodic period. The proposed model includes a Latent phase: patients at "ultra-high-risk" for developing BD, characterized by a family history of BD, temperament traits, mood, and anxiety symptoms as well as genetic vulnerability for developing the disorder; Stage I: patients who return to their baseline level of functioning when mood episodes resolve; Stage II: biomarkers and functioning impairment are related to comorbidities or rapid-…
Beyond the sensorimotor plasticity: cognitive expansion of prism adaptation in healthy individuals.
2016
Sensorimotor plasticity allows us to maintain an efficient motor behavior in reaction to environmental changes. One of the classical models for the study of sensorimotor plasticity is prism adaptation. It consists of pointing to visual targets while wearing prismatic lenses that shift the visual field laterally. The conditions of the development of the plasticity and the sensorimotor after-effects have been extensively studied for more than a century. However, the interest taken in this phenomenon was considerably increased since the demonstration of neglect rehabilitation following prism adaptation by Rossetti and his colleagues in 1998. Mirror effects, i.e. simulation of neglect in health…
Class discovery from semi-structured EEG data for affective computing and personalisation
2017
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. Many approaches to recognising emotions from metrical data such as EEG signals rely on identifying a very small number of classes and to train a classifier. The interpretation of these classes varies from a single emotion such as stress [24] to features of emotional model such as valence-arousal [4]. There are two major issues here. First classification approach limits the analysis of the data within the selected classes and is also highly dependent on training data/cycles, all of which limits generalisation. Second issue is that it does not exp…
What happens in the course of body exposure?
2007
Abstract Objective Though body exposure seems to enhance outcome in cognitive-behavioural therapy of anorexia and bulimia nervosa, the underlying mechanisms are still unknown. Methods Participants with eating disorders (ED; n = 21) and normal controls (NC; n = 28) were exposed to their own bodies in front of a mirror for 40 minutes under standardized conditions. Emotions, cognitions, and saliva cortisol were assessed every 10 minutes during body exposure. Heart rate and skin conductance were recorded continuously. Results ED showed higher negative emotional and cognitive responses to body exposure compared to NC, whereas no group differences were found for physiological reactions. In the co…
