The politics of pro-outsider labour market reforms: A configurational study
Marques, P.; Branco, R.; Guimarães, R.Over the past decades, the level of regulation of fixed-term contracts has been in flux. Many reforms deregulating these contracts were followed by a regulatory countertrend, a puzzling finding considering influential theoretical expectations like the ones developed by the dualization and liberalization literatures. This paper draws on the comparative employment relations and comparative political economy liter...
Under which conditions do unions succeed in pushing back dualization? A configu...
Marques, P.; Benassi, C.; Costa, A.; Pinto, A.This article explores the conditions under which unions achieve inclusive outcomes for nonstandard workers in their collective agreements. Using fsQCA, it compares 52 collective agreements signed in Portugal between 2003 and 2019. Additionally, it reports on three short case studies. Results show that the unions’ potential to mobilize resources in favour of outsiders is crucial and is due to either high union d...
Exercise intensity agreement, need satisfaction, and exercise behavior: A sex-m...
Teixeira, D. S.; Andrade, A. J.; Faria, J.; Marques, P.; Bastos, V.; Rodrigues, F.; Sousa, A. M.; Pereira, H. V.Several theoretical frameworks have been used to understand exercise adherence. Basic psychological needs (BPN), grounded on self‐determination theory, have received large attention for this purpose. More recently, the hedonic theory and the assumptions related to the exercise characteristics (e.g., intensity) that can bolster positive affective responses have been revitalized. This study aimed to explore the a...

Assessing the detection of floating plastic litter with advanced remote sensing...
de Fockert, A.; Eleveld, M. A.; Bakker, W.; Felício, J. M.; Costa, T. S.; Vala, M.; Marques, P.; Leonor, N.; Moreira, A.; Costa, J. R.Remote sensing technologies have the potential to support monitoring of floating plastic litter in aquatic environments. An experimental campaign was carried out in a large-scale hydrodynamic test facility to explore the detectability of floating plastics in ocean waves, comparing and contrasting different microwave and optical remote sensing technologies. The extensive experiments revealed that detection of pl...
On the feasibility of using Passive mm-Wave Imaging for marine litter detection...
Vala, M.; Felício, J. M.; Costa, T. S. da.; Leonor, N.; Costa, J. R.; Marques, P.; Moreira, A. A.; Matos, S. A.; Caldeirinha, R. F. S.; Fernandes, C. A.Large research effort is appearing in the literature on remote detection of plastic marine litter, using optical instruments, and lately microwaves. We present here a feasibility study of passive mm-wave imaging (PMMWI) for the same goal. Several measurements were taken in a controlled pool environment both in static and agitated water conditions using a W-band radiometer to assess the influence of plastic on t...
Detection of low permittivity floating plastic sheets at microwave frequencies
Costa, T. S. da.; Felício, J. M.; Vala, M.; Leonor, N.; Costa, J. R.; Marques, P.; Moreira, A. A.; Caldeirinha, R.; Matos, S. A.; Fernandes, C. A.Microwaves are surfacing in remote sensing as a viable or complementary technology to optical techniques for the detection and monitoring of floating plastic litter, given their advantages in, e.g., earth observation missions. There is a limited number of studies that analyze the detection of low permittivity plastics in a systematic manner. To contribute to this topic, we evaluated the microwave response of a ...
Regulating platforms in the passenger transport sector in Portugal and Spain: D...
Guerreiro, L. A. C.; Marques, P.Digital Platform Work (DPW) is part of a new phase of capitalism, in which monopolistic digital platforms use algorithms to mediate labour supply and demand. As DPW grows, the share of atypical workers in the labour market increases and European Union states are pressed to regulate it, but the strategies adopted are different. This is the case with the regulation of DPW in the passenger transport sector approve...
The preference for and tolerance of exercise intensity: an exploratory analysis...
Marques, P.; Andrade, A. J.; Evmenenko, A.; Monteiro, D.; Faria, J.; Rodrigues, F.; Cid, Luis; Teixeira, D. S.Health clubs are considered one of the most relevant contexts of exercise. However, they suffer from high dropout rates and struggle to keep exercisers enrolled in the long run. Considering the exercise intensity-affect relation, the main objective of this exploratory study was to test the relation of the discrepancy between the intensity traits and current exercise training intensity, and possible differences ...
