El día más difícil del rey. Discursos de legitimación monárquica desde la ficción televisiva
2015
This essay examines the representation of the political process which led to the establishment and subsequent consolidation of the constitutional monarchy in recent Spanish TV fiction. It also aims at finding out what these stories reveal about the context of crisis which has engendered them. The paper focuses on the paradigmatic case of 23-F, el día más difícil del Rey - a highly popular TV drama released by the state-owned channel TVE in February 2009 - in order to analyze the discourse of monarchic legitimacy it conveys.
Mood congruence effect in explicit and implicit memory tasks: a comparison between depressed patients, schizophrenic patients and controls
1993
Summary This study investigates mood congruence effect in explicit and implicit memory tasks in 23 inpatients fulfilling DSM-III-R criteria for major depressive disorder. Performances were compared to those of 15 in- or outpatients fulfilling DSM-III-R criteria for schizophrenia, and 37 normal subjects serving as euthymics controls. All subjects were submitted to a standard cued recall test and to a word stem completion test devised to assess the effect of the initial presentation without the explicit retrieval of the words being necessary. The material used for these two tasks consisted of emotionally negative and positive words. The results show a mood congruence effect in the ```implicit…

The role of attention in preschoolers’ working memory
2015
Abstract Recent studies showed that introducing an unfilled delay or a secondary task between encoding and recall reduces recall performance in preschoolers, whereas increasing the attentional demand of this secondary task does not. Based on these results, different authors drew opposing conclusions regarding the use of attention in preschoolers’ memory maintenance. This study aimed to bring further evidence to bear on the issue. In two experiments, recall was reduced when an unfilled delay was introduced before recall, but also when the demand of the concurrent task increased. These effects did not interact with age, although performance improved from 4 to 6 years of age. A third experimen…
VLBI-resolution radio-map algorithms: Performance analysis of different levels of data-sharing on multi-socket, multi-core architectures
2012
a b s t r a c t A broad area in astronomy focuses on simulating extragalactic objects based on Very Long Baseline Interferometry (VLBI) radio-maps. Several algorithms in this scope simulate what would be the observed radio-maps if emitted from a predefined extragalactic object. This work analyzes the performance and scaling of this kind of algorithms on multi-socket, multi-core architectures. In particular, we evaluate a sharing approach, a privatizing approach and a hybrid approach on systems with complex memory hierarchy that includes shared Last Level Cache (LLC). In addition, we investigate which manual processes can be systematized and then automated in future works. The experiments sh…
Suffix Array Construction on Multi-GPU Systems
2019
Suffix arrays are prevalent data structures being fundamental to a wide range of applications including bioinformatics, data compression, and information retrieval. Therefore, various algorithms for (parallel) suffix array construction both on CPUs and GPUs have been proposed over the years. Although providing significant speedup over their CPU-based counterparts, existing GPU implementations share a common disadvantage: input text sizes are limited by the scarce memory of a single GPU. In this paper, we overcome aforementioned memory limitations by exploiting multi-GPU nodes featuring fast NVLink interconnects. In order to achieve high performance for this communication-intensive task, we …

Background and objectives Music has a unique capacity to evoke both strong emotions and vivid autobiographical memories. Previous music information retrieval (MIR) studies have shown that the emotional experience of music is influenced by a combination of musical features, including tonal, rhythmic, and loudness features. Here, our aim was to explore the relationship between music-evoked emotions and music-evoked memories and how musical features (derived with MIR) can predict them both. Methods Healthy older adults (N = 113, age ≥ 60 years) participated in a listening task in which they rated a total of 140 song excerpts comprising folk songs and popular songs from 1950s to 1980s on five …
The Relationship Between Polygenic Risk Scores and Cognition in Schizophrenia
2020
Abstract Background Cognitive impairment is a clinically important feature of schizophrenia. Polygenic risk score (PRS) methods have demonstrated genetic overlap between schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), educational attainment (EA), and IQ, but very few studies have examined associations between these PRS and cognitive phenotypes within schizophrenia cases. Methods We combined genetic and cognitive data in 3034 schizophrenia cases from 11 samples using the general intelligence factor g as the primary measure of cognition. We used linear regression to examine the association between cognition and PRS for EA, IQ, schizophrenia, BD, and MDD. The results wer…
