Apuntes de Psicología, 18 (1), 159-177.El presente artículo se centra en el estudio de la autoeficacia como constructo significativo para el análisis y evaluación de la motivación en el trabajo. Sustituye con ventaja el concepto de expectativa de Vroom y ofrece información útil para el diagnóstico y la intervención en la motivación. Basándose en la Escala de autoeficacia general de Jerusalem y Schwarzer y su adaptación española realizada por Baesssler y Schwarzer, los autores de este artículo realizaron una nueva versión de la misma centrada en la autoeficacia general frente al trabajo y la integraron en un instrumento más complejo para el diagnóstico de la motivación. Se ofrecen resultados de la validez y fiabilidad de la escala, así como de su funcionamiento en relación al instrumento más complejo en el que se integra.This paper center in the contributions of self-efficacy to the analysis and evaluation of work motivation. It is argued thet the concept of self-efficacy succesfully replaces Vroom’s concept of expectancy , and offers useful information for diagnose and intervention in motivation. Authors adapt Baessler and Schwarzer’s Spanish adaptation of the Jerusalem and Schwarzer’s Scale of General Self-efficacy, to work situations and integrate it in a broader instrument to motivation diagnose. Validity and rehability data are presented and relations among subscales are considered

A Methodology to Engineer and Validate Dynamic Multi-level Multi-agent Based Simulations

This article proposes a methodology to model and simulate complex systems, based on IRM4MLS, a generic agent-based meta-model able to deal with multi-level systems. This methodology permits the engineering of dynamic multi-level agent-based models, to represent complex systems over several scales and domains of interest. Its goal is to simulate a phenomenon using dynamically the lightest representation to save computer resources without loss of information. This methodology is based on two mechanisms: (1) the activation or deactivation of agents representing different domain parts of the same phenomenon and (2) the aggregation or disaggregation of agents representing the same phenomenon at different scales.Comment: Presented at 3th International Workshop on Multi-Agent Based Simulation, Valencia, Spain, 5th June 201

A case of atypical disseminated herpes simplex virus 1 with hepatitis in a liver transplant recipient: the need for dermatologic evaluation

Disseminated herpes simplex virus (HSV) is mainly seen in immunocompromised individuals. Atypical lesions can be present in both primary infection and reactivation disease. Compared with the general population, inmunocompromised hosts are at greater risk of increased persistency and severity of clinical manifestations, including severe systemic involvement such as esophagitis, meningitis, and hepatitis. Herein, we report the case of a liver transplant recipient with atypical disseminated herpes simplex virus-1 complicated by HSV-related hepatitis. Dermatological consultation and histological assessment were crucial for a correct diagnosis and treatment

Intercellular ultrafast Ca(2+) wave in vascular smooth muscle cells: numerical and experimental study.

Vascular smooth muscle cells exhibit intercellular Ca(2+) waves in response to local mechanical or KCl stimulation. Recently, a new type of intercellular Ca(2+) wave was observed in vitro in a linear arrangement of smooth muscle cells. The intercellular wave was denominated ultrafast Ca(2+) wave and it was suggested to be the result of the interplay between membrane potential and Ca(2+) dynamics which depended on influx of extracellular Ca(2+), cell membrane depolarization and its intercel- lular propagation. In the present study we measured experimentally the conduction velocity of the membrane depolarization and performed simulations of the ultrafast Ca(2+) wave along coupled smooth muscle cells. Numerical results reproduced a wide spectrum of experimental observations, including Ca(2+) wave velocity, electrotonic membrane depolarization along the network, effects of inhibitors and independence of the Ca(2+) wave speed on the intracellular stores. The numerical data also provided new physiological insights suggesting ranges of crucial model parameters that may be altered experimentally and that could significantly affect wave kinetics allowing the modulation of the wave characteristics experimentally. Numerical and experimental results supported the hypothesis that the propagation of membrane depolarization acts as an intercellular messenger mediating intercellular ultrafast Ca(2+) waves in smooth muscle cells

An Eigenvector-Based Test for Local Stationarity Applied to Array Processing

In sonar array processing, a challenging problem is the estimation of the data covariance matrix in the presence of moving targets in the water column, since the time interval of data local stationarity is limited. This work describes an eigenvector-based method for proper data segmentation into intervals that exhibit local stationarity, providing data-driven higher bounds for the number of snapshots available for computation of time-varying sample covariance matrices. Application of the test is illustrated with simulated data in a horizontal array for the detection of a quiet source in the presence of a loud interferer

Magnetospheric Accretion in Close Pre-Main-Sequence Binaries

The transfer of matter between a circumbinary disk and a young binary system remains poorly understood, obscuring the interpretation of accretion indicators. To explore the behavior of these indicators in multiple systems, we have performed the first systematic time-domain study of young binaries in the ultraviolet. We obtained far- and near-ultraviolet HST/COS spectra of the young spectroscopic binaries DQ Tau and UZ Tau E. Here we focus on the continuum from 2800 to 3200 Å and on the C iv doublet (λλ1548.19, 1550.77 Å) as accretion diagnostics. Each system was observed over three or four consecutive binary orbits, at phases ~0, 0.2, 0.5, and 0.7. Those observations are complemented by ground-based U-band measurements. Contrary to model predictions, we do not detect any clear correlation between accretion luminosity and phase. Further, we do not detect any correlation between C iv flux and phase. For both stars the appearance of the C iv line is similar to that of single Classical T Tauri Stars (CTTSs), despite the lack of stable long-lived circumstellar disks. However, unlike the case in single CTTSs, the narrow and broad components of the C iv lines are uncorrelated, and we argue that the narrow component is powered by processes other than accretion, such as flares in the stellar magnetospheres and/or enhanced activity in the upper atmosphere. We find that both stars contribute equally to the narrow component C iv flux in DQ Tau, but the primary dominates the narrow component C iv emission in UZ Tau E. The C iv broad component flux is correlated with other accretion indicators, suggesting an accretion origin. However, the line is blueshifted, which is inconsistent with its origin in an infall flow close to the star. It is possible that the complicated geometry of the region, as well as turbulence in the shock region, are responsible for the blueshifted line profiles

Grupos en las organizaciones: herramienta básica para gestionar la incertidumbre y ambigüedad crecientes

El mundo del trabajo y de las organizaciones ha sufrido una transformación fundamental en los últimos años: hay mucha más incertidumbre. La respuesta organizativa a dicha incertidumbre ha sido la de diseñar organizaciones más complejas fundamentadas en el trabajo en equipo. Pero no todas las tareas requieren del trabajo en equipo ni todos los grupos de trabajo son auténticos equipos. En este trabajo repasaremos las investigaciones que venimos realizando para clarificar cómo entender operativamente la incertidumbre de las tareas que ha de hacer el equipo, el nivel de desarrollo que pueden alcanzar los equipos de trabajo y cómo el ajuste entre uno y otro (a mayor incertidumbre en las tareas más necesario su abordaje en equipos) es determinante en la efectividad que dichos equipos consiguen. Ofrecemos también guías para la intervención profesional si el objetivo es diseñar y dirigir equipos de trabajo eficaces

Aesthetics of Resistance in Western Sahara

In reaction to neo-liberal globalization policies that were spearheaded in the 1980s by Reagan-economics and Thatcherism, indignant movements ignited globally in distinct places, spaces, and territories, using diverse resistance strategies, both violent and nonviolent. Today, two years into the new social media revolutions, with the “Arab Spring” (in Tunisia known as Sidi Bouzid Revolt, in Libya as the Revolution of February 17th, and in Egypt as Revolution of January 25th), the “indignado/a” movement in Spain, and “Occupy Wall Street” in the United States, what does it mean to be “indignant”?Within an interdisciplinary Peace Studies and Research context, how do we begin to talk about and theorize this (inter)subjective move from being a “victim” to being “indignant?” And, how do we do so in a way that captures the complex and multi-layered dimensions of liberation struggles? We begin with a theoretical overview in order to frame the discussion. We then specifically examine the “Sahrawi Spring” in order to see theory in practice. As Africa’s last colony,Western Sahara provides an interesting look into the aesthetics of resistance
