Occupational cognitive complexity and episodic memory in old age
2021
The aim of this study was to investigate occupational cognitive complexity of main lifetime occupation in relation to level and 15-year change in episodic memory recall in a sample of older adults (≥ 65 years, n = 780). We used latent growth curve modelling with occupational cognitive complexity (O*NET indicators) as independent variable. Subgroup analyses in a sample of middle-aged (mean: 49.9 years) men (n = 260) were additionally performed to investigate if a general cognitive ability (g) factor at age 18 was predictive of future occupational cognitive complexity and cognitive performance in midlife. For the older sample, a higher level of occupational cognitive complexity was related to…
Nos inventamos un mundo que no existía. Una profesión de riesgo: ser editora durante el franquismo
2021
Desde el final de la dictadura franquista, la censura editorial se ha constituido en un objeto de estudio interdisciplinar que, al inicial análisis de la constitución y entramado de la censura, incorpora el estudio de una casuística varia que redimensiona el fenómeno. Por un lado, en el contexto de los memory studies, cabe analizar qué efectos tuvo en la configuración de la memoria cultural. Por otro, tiene, además, una notable incidencia en la edición, por la autocensura y la contracensura. En concreto, este artículo explora la labor de algunas editoras que, en la Barcelona de los años sesenta y setenta, integraron una generación histórica opuesta al franquismo que lidió con la censura en …
Fluctuation theorems for non-Markovian quantum processes
2013
Exploiting previous results on Markovian dynamics and fluctuation theorems, we study the consequences of memory effects on single realizations of nonequilibrium processes within an open system approach. The entropy production along single trajectories for forward and backward processes is obtained with the help of a recently proposed classical-like non-Markovian stochastic unravelling, which is demonstrated to lead to a correction of the standard entropic fluctuation theorem. This correction is interpreted as resulting from the interplay between the information extracted from the system through measurements and the flow of information from the environment to the open system: Due to memory e…
Memory Effects in High-Dimensional Systems Faithfully Identified by Hilbert–Schmidt Speed-Based Witness
2022
A witness of non-Markovianity based on the Hilbert–Schmidt speed (HSS), a special type of quantum statistical speed, has been recently introduced for low-dimensional quantum systems. Such a non-Markovianity witness is particularly useful, being easily computable since no diagonalization of the system density matrix is required. We investigate the sensitivity of this HSS-based witness to detect non-Markovianity in various high-dimensional and multipartite open quantum systems with finite Hilbert spaces. We find that the time behaviors of the HSS-based witness are always in agreement with those of quantum negativity or quantum correlation measure. These results show that the HSS-based witness…
Effect of methyl jasmonate in gene expression, and in hormonal and phenolic profiles of holm oak embryogenic lines before and after infection with Ph…
2022
The dieback syndrome affecting Quercus ilex and other oak species impels the search for tolerant plant genotypes, as well as methods of plant immunization against such infections. Elicitation treatments can be an effective strategy to activate plant defense response and embryogenic lines represent a promising tool to generate new tolerant genotypes and also to study early markers involved in defense response. The aim of the presented work was to investigate changes in gene expression, and in hormonal and phenolic profiles induced in three holm oak embryogenic lines (ELs) elicited with methyl jasmonate (MeJA) before and after infection with the oomycete Phytophthora cinnamomi, which is the m…
Expand your body when you look at yourself: The role of the posture in a mirror exposure task
2018
Mirror exposure (ME) is one of the main components of the treatment of patients with eating disorders symptomatology and it has shown its effectiveness in improving several outcomes (e.g., body dissatisfaction). However, the study as to what body posture should be adopted to maximize its effectiveness has been neglected. From embodied cognition and emotion theories, the adoption of an expansive (vs. contractive) body posture has been associated with positive changes in cognitive and emotional responses. The objective of this study was to analyze the effect of adopting an expansive (vs. contractive) posture before an ME task on body-related emotions and cognitions, as well as to analyze the …
How COVID-19 kick-started online learning in medical education-The DigiMed study.
2021
Background The coronavirus disease 2019 (COVID-19) pandemic led to far-reaching restrictions of social and professional life, affecting societies all over the world. To contain the virus, medical schools had to restructure their curriculum by switching to online learning. However, only few medical schools had implemented such novel learning concepts. We aimed to evaluate students’ attitudes to online learning to provide a broad scientific basis to guide future development of medical education. Methods Overall, 3286 medical students from 12 different countries participated in this cross-sectional, web-based study investigating various aspects of online learning in medical education. On a 7-…
Contribution à la caractérisation de la mémoire des aliments
2008
Memory plays a fundamental role in the acquisition of food likes and dislikes. As a consequence, a better understanding food memory will contribute to a better understanding food choice and behavior. This work sets out several experiments based on a common recognition paradigm: during a first session, participants are exposed to the food to be remembered (target) under conditions ensuring incidental learning. After a certain retention interval, participants are asked to recognize the target among a set of distractors with a flavor and/or a texture slightly different from the target. In line with previous works on food memory, three main results emerged from this work. First, participants of…
Radiation effects in nitride read-only memories
2010
Abstract We report on the influence of different types of radiation on the nitride read-only memories (NROM®). The memory cells were irradiated by light ions (Boron), X-rays and γ-rays. Memory transistor parameters, such as threshold voltage and subthreshold drain leakage were studied as a function of the accumulated radiation dose and compared to the as-programmed (-erased) devices parameters. Their time evolution was registered in the range from few hours up to 5 months after the irradiation. The NROM® cells showed good radiation robustness up to high accumulated doses. Sufficient program margin (difference of threshold voltage in the programmed state and the read-out voltage level) remai…
Maintaining information in Short-Term Memory between 2 and 6 years old of age : temporal forgetting and helping in maintaining the goal
2014
Working memory is an essential component of thought that is highly involved in learning and academic achievement. However, it is rarely studied in preschoolers, mainly because of a lack of suitable paradigms. Therefore, this thesis investigated the functioning of working memory in children between 2 and 6 years. For this purpose, two original paradigms were used. They were designed to be close to game situations which should help young children to focus their attention on the task. Firstly it was shown that the recall performance decreased over time, even in the absence of an interfering task. Children of this age therefore use a passive maintenance, i.e. without spontaneously implementing …
