Genetic features of Multi Drug Resistant (MDR) Klebsiella pneumoniae and its Plasmids
2019
Klebsiella pneumoniae, a major cause of both hospital and community-acquired infections, is listed by the World Health Organization as a critical priority antibiotic- resistant bacterial pathogen. With the appearance of sequencing techniques such as Next-generation Sequencing (NGS), there is the possibility to obtain the whole genome of the bacteria, getting to know all antimicrobial resistance determinants. The purpose of this study has been to apply this new technology to clinical microbiology, in order to characterize the resistome present in carbapenem-resistant K.pneumoniae strains isolated in a tertiary hospital in Valencia, Spain. A total of 234 isolates were prepared for whole-genom…
Melting point, molecular symmetry and aggregation of tetrachlorobenzene isomers: the role of halogen bonding
2018
Tetrachlorobenzenes represent one of the best known, but not yet fully understood, group of isomers of the structure–melting point relationship. The differences in melting temperatures of these structurally related compounds were rationalized in terms of the hierarchy and nature of formed noncovalent interactions, and the molecular aggregation that is influenced by molecular symmetry. The highest melting point is associated with the highly symmetric 1,2,4,5-tetrachlorobenzene isomer. The structures of less symmetrical 1,2,3,4-tetrachlorobenzene and 1,2,3,5-tetrachlorobenzene, determined at 270 and 90 K, show a distinct pattern of halogen bonds, characterized by the different numbers and typ…
Hippocampal theta phase-contingent memory retrieval in delay and trace eyeblink conditioning
2017
Hippocampal theta oscillations (3–12 Hz) play a prominent role in learning. It has been suggested that encoding and retrieval of memories are supported by different phases of the theta cycle. Our previous study on trace eyeblink conditioning in rabbits suggests that the timing of the conditioned stimulus (CS) in relation to theta phase affects encoding but not retrieval of the memory trace. Here, we directly tested the effects of hippocampal theta phase on memory retrieval in two experiments conducted on adult female New Zealand White rabbits. In Experiment 1, animals were trained in trace eyeblink conditioning followed by extinction, and memory retrieval was tested by presenting the CS at …
Learning to learn: Theta oscillations predict new learning, which enhances related learning and neurogenesis
2012
Animals in the natural world continuously encounter learning experiences of varying degrees of novelty. New neurons in the hippocampus are especially responsive to learning associations between novel events and more cells survive if a novel and challenging task is learned. One might wonder whether new neurons would be rescued from death upon each new learning experience or whether there is an internal control system that limits the number of cells that are retained as a function of learning. In this experiment, it was hypothesized that learning a task that was similar in content to one already learned previously would not increase cell survival. We further hypothesized that in situations in…
Desempleo y crisis Económica. Los casos de España e Italia
2018
En este artículo se analiza la diferente reacción que los mercados laborales italiano y español han tenido ante la crisis económica: la tasa de paro italiana entre 2006 y 2012, ha crecido relativamente poco (pasando del 7,6 al 10,9%) mientras que la es-pañola se ha casi triplicado, pasando del 9 al 24,4%. Para ello se han analizado datos relativos a: el mercado del trabajo, la situación socioeconómica y la legislación exis-tente. Tras el estudio realizado, tres parecen ser las discrepancias más relevantes: 1) las diferencias en las tasas de actividad femenina entre ambos países; 2) la menor apertura del mercado laboral italiano en los últimos 20 años; y, 3) la diferente legis-lación sobre d…
Merit, Competition, Distinction
2018
The article presents a critique of competition by introducing a concept called 'distinction'. Competition is thought to work as a guarantee of the fairness of meritocratic procedures (merit-based recruiting in the job market or e.g. entrance examinations). However, fairness created by competition is, even at its best, only relative. This critique is then used a part of a larger critique of the role of merit in society.
Comprehension control of English texts with Secondary Compulsory Education students, with English as a second language
2017
Este trabajo gira en torno a la investigación del Control de la Comprensión en estudiantes de Educación Secundaria Obligatoria y Bachillerato. El objetivo del trabajo es averiguar el nivel de Control de la Comprensión de los alumnos, ver si hay una mejora a través de los cursos, y observar si los alumnos de último curso, Segundo de Bachillerato, tienen un Control de Comprensión suficiente para enfrentarse a el nivel académico universitario. Como metodología, se utilizó un test de autoevaluación y dos textos por cada clase al que se le insertaron cuatro errores que había que detectar. Como resultado, se pudo comparar la percepción del alumno de su propio control de la comprensión, y el verda…

L’épistémologie de Jean Bollack ou Bollack contre Bollack
2015
International audience; Jean Bollack’s philologische Wissenschaft aims to reach the “good lesson” of a text and to get the “original intent” of its author, in the true sense of these expressions. It is based on three main elements: the identification of biases that would lead to an incorrect interpretation; the syntactic analysis of the text and the discussion of the points of view of other scholars (i.e. a dialectical criticism). Bollack – despite his accuracy – does not question his own assumptions: 1) that the sense of a text is in the manuscripts we possess (or – in any case – it is recoverable through them); 2) the idea that the great texts are more insightful than others; and 3) the n…
Storytelling im frühkindlichen Fremdsprachenerwerb am Beispiel eines im Kindergarten Nr. 8 in Opole realisierten Projektes
2017
Metoda narracyjna, która swój niewątpliwy sukces odnosi w specjalistycznych szkoleniach personalnych i tzw. caochingu, uznawana była przez dłuższy czas jako zarezerwowana dla świata biznesu. Coraz częściej stosuje się ją jednak także w metodyce nauczania języków obcych, gdzie jej skuteczność zauważono szczególnie w pracy z dziećmi na etapie przedszkolnym i wczesnoszkolnym. Uczestnictwo grupy studentów w opisanym w tym artykule projekcie, który zakładał zastosowanie założeń storytellingu do przygotowania i przeprowadzenia zajęć z języka niemieckiego dla dzieci, było dla nich przede wszystkim szansą zdobycia doświadczenia w zakresie organizacji procesu nauczania języka przyjaznego uczniowi. A…
