Studying Within-Person Changes in Work Motivation in the Short and MediumTerm: You Will Likely Need More Measurement Points than You Think!
(European Journal of Work and Organizational Psychology, 2022)Within-person analysis of data from longitudinal designs has become popular in the field. However, important characteristics of the design can influence that variability. In this paper, we examine how ... -
Daily work engagement is a process through which daily micro-events at work influence life satisfaction
(International Journal of Manpower, 2023)Purpose: Drawing upon the conservation of resources theory, the authors expected that daily micro-events, daily hassles and uplifts at work influenced well-being via work engagement at the daily ... -

The Systemic Governance Influence of Expectation Documents: Evidence from a Universal Owner
(The Review of Corporate Finance Studies, 2024)We examine expectation documents’ effectiveness as an activism tool. We use the Norwegian sovereign wealth fund’s release of a corporate governance expectation document as a natural experiment. We ... -
Controlling chaotic oscillations in a symmetric two-mass model of the vocal folds
(Chaos, Solitons & Fractals, Vol. 159 , 2022 (juny), 2022-06)Human phonation is a highly non-linear process in which subglottal flow emanating from the lungs induces self-oscillations of the vocal folds. In normal conditions, this results in the generation of a ... -
Robustness of a pacemaker to control chaotic oscillations in a two-mass model of the vocal folds under turbulence and muscle twitch fluctuations and vocal tremor
(Communications in Nonlinear Science and Numerical Simulation. 2025. Vol. 140, part. 1., 2025-01)A pacemaker for phonation could be feasible in the near future thanks to advances in smart materials technology. However, before attempting it, much theoretical work needs to be done to figure out how ... -
Finite element hybrid and direct computational aeroacoustics at low Mach numbers in slow time-dependent domains
(Computers & Fluids, 2022, Vol. 239 (Maig), 2022-05-15)In this work, we address the finite element computation of flow noise in the presence of arbitrarily slowly moving rigid bodies at low Mach numbers, by means of hybrid and direct computational aeroacoustics ... -
Format frequency tuning of three-dimensional MRI-based vocal tracts for the finite element synthesis of vowels
(IEEE/ACM Transactions on Audio Speech and Language Processing, 2024. Vol. 32, p. 2790-2799, 2024-05)Nowadays it is possible to acquire three-dimensional (3D) geometries of the vocal tract by means of Magnetic Resonance Imaging (MRI) and introduce them into a 3D acoustic model to obtain their frequency ... -
A-Place. Linking places through networked artistic practices
(2025-01)The aim of A-Place, a project co-funded by the Creative Europe programme, has been to create a network of places across countries and cultures, artistic forms and educational fields, involving professional ... -
Controlling chaotic vocal fold oscillations in the numerical production of vowel sounds
(Chaos, Solitons & Fractals Volume 182, May 2024, 114740, 2024-03)Lumped mass models have been studied in depth to unveil the complex nonlinear physics of phonation. Even in the case of simple symmetric models, slight changes in muscle restoring forces or excessive ... -
Tuned two-dimensional vocal tracts with piriform fossae for the finite element simulation of vowels
(Journal of Sound and Vibration, Vol. 537, Art. 117168, 2022-07)The piriform fossae are two small side branches of the vocal tract that are located close to the larynx. They act as quarter wave resonators and introduce two deep dips around 5 kHz in the voice spectrum. ... -
Analysis of caesarean section rates using the Robson classification system at a university hospital in Spain
(International Journal of Environmental Research and Public Health, 2020, 17(5): 1575, 2020-02)Background: The WHO recommends the use of the Robson ten-group classification system (RTGCS) as an effective monitoring and analysis tool to assess the use of caesarean sections (CS). The present study ... -
