Using the Panel of Social Inequalities in Catalonia, Spain (PaD 2001–2012), this article investigates the relationship between perceptions of economic conditions and subjective well-being in times of prosperity and economic crisis. It also analyses how this relation- ship plays out across different social backgrounds. Periods of economic crisis and prosper- ity serve as a proxy for objective macroeconomic conditions. The Spanish region of Cata- lonia is a relevant setting because it faced one of the highest increases in inequality and unemployment in Europe as a result of the 2008 Economic Crisis. Our results show that perceived economic conditions matter beyond objective micro and macroeconomic realm and become a strong determinant of subjective well-being during a crisis, particularly for the middle class. However, contrary to our initial expectations, our results also show the existence of a close correlation between perceptions of economic conditions and subjective well-being for low social background individuals in times of economic prosperity, and an even stronger relationship in times of economic crisis. The article stipulates several poten- tial explanations for these results. [less ▲]

It is still debated whether suppressing the retrieval of unwanted memories causes forgetting and whether this constitutes a beneficial mechanism. To shed light on these 2 questions, we scrutinize the evidence for such suppression-induced forgetting (SIF) and examine whether it is deficient in psychological disorders characterized by intrusive thoughts. Specifically, we performed a focused meta-analysis of studies that have used the think/no-think procedure to test SIF in individuals either affected by psychological disorders or exhibiting high scores on related traits. Overall, across 96 effects from 25 studies, we found that avoiding retrieval leads to significant forgetting in healthy individuals, with a small to moderate effect size (0.28, 95% CI [0.14, 0.43]). Importantly, this effect was indeed larger than for more anxious (−0.21, 95% CI [−0.41, −0.02]) or depressed individuals (0.05, 95% CI [−0.19, 0.29])—though estimates for the healthy may be inflated by publication bias. In contrast, individuals with a stronger repressive coping style showed greater SIF (0.42, 95% CI [0.32, 0.52]). Furthermore, moderator analyses revealed that SIF varied with the exact suppression mechanism that participants were instructed to engage. For healthy individuals, the effect sizes were considerably larger when instructions induced specific mechanisms of direct retrieval suppression or thought substitution than when they were unspecific. These results suggest that intact suppression-induced forgetting is a hallmark of psychological well-being, and that inducing more specific suppression mechanisms fosters voluntary forgetting.

Fractures of the anterior pelvic ring reduce patients` mobility and independence and increase mortality. Pelvic instability impairs the load transfer to the lower extremity. Restoring stability has therefore been a crucial point of research. Most of the reported studies refer to loading on one leg stand without consideration of physiological muscle and contact-joint forces of the common vital daily movements. Our present study considers physiological gait loading of all acting muscles and Hip Joint Contact (HJC) forces of the pelvis. Those muscles and HJC forces were calculated by inverse dynamics for normal gait motion data and applied in Finite Element Analyses (FEA). The biomechanical stability provided to the anterior pelvic ring by two reconstructive techniques was investigated numerically: the iliopubic Subcutaneous Plate (SP) and the Supra-Acetabular External Fixator (SAFE). Numerical biomechanical assessment of two reconstructive devices for pubic ramus fracture. All muscles and HJC forces of normal gait were calculated by means of inverse dynamics software for a healthy patient considering a musculoskeletal model previously validated experimentally. The Finite Element (FE) model was developed for a pelvis with and without superior and/or inferior rami fractures. Furthermore, two FE models for SP and SAFE mounted on the rami fractured pelvis were designed considering fixation bearing at the lumbosacral joint. The calculated forces were implemented on the FE models following the anatomical orientation and attachments/insertions of each muscle. During the two moments of the gait with higher stresses: Left Heel Strike (LHS) and Right Toe-Off (RTO), strains and displacements were recorded and investigated at the fracture location in addition to the implant fixation points. Considering only right superior ramus fracture during LHS and RTO, recorded strains and displacements for both implants showed similar results. However, during RTO, the SAFE showed a slight reduction of strains at the posterior location by 6% compared to SP. When including both superior and inferior right ramus fractures, both devices did not show considerable difference in recorded strains. However, there were significant differences in the displacements between fracture extremities. The SP technique reduced these motions for both LHS and RTO by 40% compared to the gold standard SAFE technique. In cases of superior ramus fracture only, displacements for both reconstructive devices were similar due to the remaining stability provided by the intact inferior ramus. Both devices reduced stresses of the sacrum wing in LHS and RTO with slightly better results for SAFE. In case of superior and inferior pubic ramus fractures, the SP technique reduced the frontal opening of the fractured right pubic bone. The SAFE did not provide any improvements compared to the SP technique. [less ▲]

The Single Frequency Networks (SFN) are widely used in Digital Television transmission networks due to the high spectral efficiency achieved by them. Digital modulation techniques with a cyclic prefix, like OFDM (Orthogonal Frequency Division Multiplex) are adequate to define and use SFN networks due to their ability to deal with the artificial multipath produced in a SFN network. Nevertheless, the ATSC 1.0 and ATSC M/H standards use the VSB-8 modulation technique, which has no cyclic prefix, so it is very sensitive to multipath. The ATSC 1.0 standard has been recently implemented in Mexico, so the ATSC M/H standard can be used in the next years because it is compatible with ATSC 1.0, meanwhile ATSC 3.0, the newest standard of ATSC, it is not compatible.The performance of the reception with VSB-8 modulation depends strongly on the receiver channel equalizer. For this reason, the objective of this study is to analyze the performance of ATSC M/H commercial receivers in SFN networks. The results of this study will help in the implementation of SFN networks in Mexico and other countries that use ATSC 1.0 and ATSC M/H. [less ▲]

This paper seeks to show how language, combined with other social variables, exacerbates migrants’ and their descendants’ struggles at school and beyond in Luxembourg. To a certain extent, the official trilingualism of Luxembourg – French, German and Luxembourgish – corresponds to an ‘elite multilingualism’ (Garrido 2017; Barakos and Selleck 2018) which defines who can access certain resources, e. g. education, work etc., and who can be left playing catch-up. The latter are those migrants who I here conceive as multilinguals on the margins. The elitist system is a form of domination and power over those whose language repertoire is less valued. Migrants’ disadvantage is further impacted by other indicators of their identity that can go beyond their educational qualifications and language repertoire per se, such as their country of origin, ethnicity, race, gender, citizenship etc. Language intersects with other forms of disadvantage or privileges. From an ethnographic sociolinguistic perspective, drawing on interviews and participant observations, this paper will illustrate this intersection of language, race and ethnicity, and struggles from the ground-level educational realities and aspirations of Cape Verdean migrants and their descendants in Luxembourg. This helps cast light on the social organisation in Luxembourg and understand the effects of multilingualism in creating ‘abyssal lines’ (Santos 2007) between the nationals, certain European migrants, Lusophone and African migrants in terms of social and economic mobility.

Following the footsteps of Germaine de Staël, Benjamin Constant and especially Chateaubriand, pioneers of the modern lampoon, Paul-Louis Courier turns it into a codified and stabilized genre, with its own rhetoric, its own images and its own protagonists (particularly the « I » used by the pamphleteer). However, for the pamphleteer, making the author the main centre of interest implies justifying his writings and explaining the way he can speak on the people's behalf. Studying the lampoon and the metadiscourse relating to it implies therefore opening some sociological horizons : the lampoon emphasizes the social background of the pamphleteer, of his characters and of his readers. Considering these factors, our article aims at comparing the sociological component in Courier's and Tillier's writings, intending to assert exactly how popular 19 th Century-France lampoons are, from a sociological and a rhetorical standpoint.

The concept of geostationary VHTS (Very High Throughput Satellites) is based on multibeam coverage with intensive frequency and polarization reuse, in addition to the use of larger bandwidths in the feeder links, in order to provide high capacity satellite links at a reduced cost per Gbps in orbit. The dimensioning and design of satellite networks based on VHTS imposes the analysis of multiple trade-offs to achieve an optimal solution in terms of cost, capacity, and the figure of merit of the user terminal. In this paper, we propose a new method for sizing VHTS satellite networks based on an analytical expression of the forward link CINR (Carrier-to-Interference-plus-Noise Ratio) that is used to evaluate the trade-off of different combinations of system parameters. The proposed method considers both technical and commercial requirements as inputs, including the constraints to achieve the optimum solution in terms of the user G/T, the number of beams, and the system cost. The cost model includes both satellite and ground segments. Exemplary results are presented with feeder links using Q/V bands, DVB-S2X and transmission methods based on CCM and VCM (Constant and Variable Coding and Modulation, respectively) in two scenarios with different service areas.

This paper explores the entanglement of language with issues such as discrimination and the reproduction of social hierarchies. It unpacks this interplay to show how the use and abuse of language serve as the main mechanism of inclusion, exclusion and limitation of migrants in the labour market, contributing to certain migrant groups and their descendants remaining in the bottom stratum of society. It investigates how language use can both empower and disqualify migrants, creating ethnic pools of work. This paper draws on interviews with a successful middle-aged Cape Verdean man, Pedrinhu, to illustrate this language impact. He came to Luxembourg at a young age and his sports skills helped him to be fast-tracked to acquire Luxembourgish citizenship. He talks about his migration trajectories, his sociolinguistic life and his job interactions with Cape Verdean workers at a private employment enterprise where he now holds a high position. He seeks “to empower” Cape Verdean migrants, challenging some of the institutionalised linguistic demands of the state employment agency he collaborates with; at the same time, he is aware of the reproduction of inequality and the ethnic stratification of his enterprise. The paper concludes by highlighting the ambivalences of multilingualism and empowerment interventions in accessing resources, such as work, in the condensed migration contexts of Luxembourg.
