Can organizational commitment be experienced by indivuals pursuing contemporary career paths?

In a context in which organizations can no longer promise life-time employment and individuals increasingly experience inter-organizational mobility, this study tackles the question of whether organizational commitment is no longer related to new career orientations. To this end, it analyzes the relation between the underlying dimensions of protean (self direction and values driven) and boundaryless (boundaryless mindset and organizational mobility preference) career attitudes (Briscoe et al., 2006) and organizational commitment, within today's unstable and uncertain business scenario. Research results suggest that protean career attitudes contribute significantly to individuals emotional attachment to their employing organization. Furthermore, organizational mobility preference was found to be significant in predicting both affective and continuance commitment. Finally, future research suggestions and practical implications associated with the current study are provided.

El tiempo libre como dinamizador y/o activador de comunidad/es

El aumento del diálogo con las ONG y los interlocutores sociales y la mejora de la coordinación entre las tres Administraciones es vital para una positiva adecuación entre normativa e intervención real a la hora de atender unas necesidades que aumentan con el actual panorama de crisis económica. No obstante, debe seguir progresándose tanto en la evaluación mediante indicadores conjuntos de la repercusión de estas iniciativas como en el aumento de la participación ciudadana en ellas

What can spike train distances tell us about the neural code?

Time scale parametric spike train distances like the Victor and the van Rossum distancesare often applied to study the neural code based on neural stimuli discrimination.Different neural coding hypotheses, such as rate or coincidence coding,can be assessed by combining a time scale parametric spike train distance with aclassifier in order to obtain the optimal discrimination performance. The time scalefor which the responses to different stimuli are distinguished best is assumed to bethe discriminative precision of the neural code. The relevance of temporal codingis evaluated by comparing the optimal discrimination performance with the oneachieved when assuming a rate code.We here characterize the measures quantifying the discrimination performance,the discriminative precision, and the relevance of temporal coding. Furthermore,we evaluate the information these quantities provide about the neural code. Weshow that the discriminative precision is too unspecific to be interpreted in termsof the time scales relevant for encoding. Accordingly, the time scale parametricnature of the distances is mainly an advantage because it allows maximizing thediscrimination performance across a whole set of measures with different sensitivitiesdetermined by the time scale parameter, but not due to the possibility toexamine the temporal properties of the neural code.

The Multiscenario Multienvironment BioSecure Multimodal Database (BMDB)

A new multimodal biometric database designed and acquired within the framework of the European BioSecure Network of Excellence is presented. It is comprised of more than 600 individuals acquired simultaneously in three scenarios: 1) over the Internet, 2) in an office environment with desktop PC, and 3) in indoor/outdoor environments with mobile portable hardware. The three scenarios include a common part of audio/video data. Also, signature and fingerprint data have been acquired both with desktop PC and mobile portable hardware. Additionally, hand and iris data were acquired in the second scenario using desktop PC. Acquisition has been conducted by 11 European institutions. Additional features of the BioSecure Multimodal Database (BMDB) are: two acquisitionsessions, several sensors in certain modalities, balanced gender and age distributions, multimodal realistic scenarios with simple and quick tasks per modality, cross-European diversity, availability of demographic data, and compatibility with other multimodal databases. The novel acquisition conditions of the BMDB allow us to perform new challenging research and evaluation of eithermonomodal or multimodal biometric systems, as in the recent BioSecure Multimodal Evaluation campaign. A description of this campaign including baseline results of individual modalities from the new database is also given. The database is expected to beavailable for research purposes through the BioSecure Association during 2008.

L'ús de la cançó per a potenciar el desenvolupament del llenguatge d'un nen autista

L’ús de la cançó per a potenciar el desenvolupament del llenguatge d’un nen autista és un projecte que pretén donar una visió de la música com a eina per al desenvolupament del llenguatge verbal i no verbal dels nens amb diagnòstic de TEA (Trastorn de l’Espectre Autista). Busca també fer una revisió bibliogràfica en aquest camp per conèixer i relacionar una mica més aquests móns sovint desconeguts. Finalment, presenta un programa d’intervenció adreçat específicament a quatre alumnes amb TEA, amb necessitats i objectius diferents, amb el pertinent seguiment, anàlisi de les dades recollides durant la intervenció, conclusions, i noves vies de treball que es podrien dur a terme.

La masia catalana Can Rigalt

Treball de recerca realitzat per un alumne d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2010. Es presenta un estudi sobre la Masia catalana i quina ha estat la seva evolució arquitectònica en concepte i forma, tenint en compte l' ubicació tan física com temporal. S’ha escollit per exemplificar l'estudi la Masia de Can Rigalt ubicada en mig de la gran urbs. El fet de la tria ha estat la proximitat de l'autora amb la família dels masovers i el poder d'aquesta manera tenir informació directa sobre la vida quotidiana, els espais emprats i la distribució arquitectònica que el temps ha anat modificant.

The dynamics of US inflation: Can monetary policy explain the changes?

We investigate the relationship between monetary policy and inflation dynamics in theUS using a medium scale structural model. The specification is estimated with Bayesiantechniques and fits the data reasonably well. Policy shocks account for a part of the declinein inflation volatility; they have been less effective in triggering inflation responses overtime and qualitatively account for the rise and fall in the level of inflation. A number ofstructural parameter variations contribute to these patterns.

Voting after the bombing: Can terrorist attacks change the outcome of democratic elections?

Economists have recently turned their attention to the effects of terrorism. One much debated effect of terrorist attacks is its impact on the results of democratic elections. We use the electoral consequences of the terrorist attacks of the 11-M in Madrid to analyze this issue. We consider this particular experiment since the attack took place only three days before the 2004 Congressional Election, which allows the use of credible identification criteria. In particular, we use the advance voting by Spanish residents abroad, who cast their vote before the terrorist attack, to identify the effect of the bombing. We exploit this macabre natural experiment to run a difference-in-differences estimation using data on three consecutive Congressional elections. Our empirical results indicate that a terrorist attack can have a large impact on the outcome of democratic elections.

Estimates of patient costs related with population morbidity: Can indirect costs affect the results?

A number of health economics works require patient cost estimates as a basic information input.However the accuracy of cost estimates remains in general unspecified. We propose to investigate howthe allocation of indirect costs or overheads can affect the estimation of patient costs in order to allow forimprovements in the analysis of patient costs estimates. Instead of focusing on the costing method, thispaper proposes to highlight changes in variance explained observed when a methodology is chosen. Wecompare three overhead allocation methods for a specific Spanish population adjusted using the ClinicalRisk Groups (CRG), and we obtain different series of full-cost group estimates. As a result, there aresignificant gains in the proportion of the variance explained, depending upon the methodology used.Furthermore, we find that the global amount of variation explained by risk adjustment models dependsmainly on direct costs and is independent of the level of aggregation used in the classification system.

Can sanctions induce pessimism? An experiment

We run an experiment in which two subjects play a two-round minimum effort game inthe presence of a third player (principal) who is the only one informed about past effortchoices and benefits from a higher minimum effort of the others. Sanctions introduced in thesecond round by the experimenter lead to more optimistic beliefs and higher efforts. This isnot true when sanctions have been imposed by the principal. The possibility that the choiceof a sanction is a signal of low effort levels causes players who chose high effort in the firstround to be less optimistic.
