Factors Influencing Lower Secondary School Pupils’ Success in Programming Projects in Scratch
2020
In the Czech Republic, a radical change in the school curriculum is planned. Through a new, compulsory subject of “Informatics and ICT”, the aim is to develop digital literacy across all school subjects, and computational thinking. Computational thinking will be implemented in the curriculum of pre-primary, primary, lower and upper secondary schools, and in teacher education at all faculties of education in the Czech Republic. To ensure readiness for the implementation of the new subject, it has been necessary to prepare and develop a set of learning materials for pupils and teaching guidelines for teachers. These textbooks focus on robotics, programming (Scratch, Python), and theoretical c…
Principled animation design improves comprehension of complex dynamics
2016
International audience; Learners can have difficulty in decomposing conventionally designed animations to obtain raw material suitable for building high quality mental models. A composition approach to designing animations based on the Animation Processing Model was developed as a principled alternative to prevailing approaches. Outcomes from studying novel and conventional animation designs (independent variable) were compared with respect to mental model quality, knowledge of local kinematics, and capacity to transfer (dependent variables). Study of a compositional animation that presented material in a contiguous fashion resulted in higher quality mental models of a piano mechanism than …
Succesio ab intestato: Concerning the death of Rodrigo de Mendoza, I Marquis of the Cenete
2017
La muerte de Rodrigo de Mendoza, I marqués del Cenete, sin testamento se vio envuelta de la incertidumbre propia del fallecimiento de un noble con un cuantioso patrimonio heredado en gran parte de su padre, el gran cardenal de España, sin especificar ni repartir y con tres hijas menores huérfanas sin un albacea designado por él. El gobernador general de Valencia, Lluís de Cabanyelles, del círculo más íntimo del marqués durante su estancia en la ciudad del Turia, junto a otros partícipes y testigos, impulsó el proceso de inventariado de todos sus bienes cuatro días después de su defunción, apelando, asimismo, al emperador Carlos V para que confirmase al virrey del reino de Valencia y hermano…
Spurious source generation in mapping from noisy phase-self-calibrated data
2008
Phase self-calibration (or selfcal) is an algorithm often used in the calibration of interferometric observations in astronomy. Although a powerful tool, this algorithm presents strong limitations when applied to data with a low signal-to-noise ratio. We analyze the artifacts that the phase selfcal algorithm produces when applied to extremely noisy data. We show how the phase selfcal may generate a spurious source in the sky from a distribution of completely random visibilities. This spurious source is indistinguishable from a real one. We numerically and analytically compute the relationship between the maximum spurious flux density generated by selfcal from noise and the particulars of th…
Assessing attention allocation toward threat-related stimuli: a comparison of the emotional Stroop task and the attentional probe task
2003
This study examined the association of two widely used measures of attention allocation toward or away from threat-related stimuli: The emotional Stroop task and the attentional probe task. Fifty-three participants responded to computer versions of both tasks where stimuli were presented both subliminally and supraliminally. Thus, four indexes indicating attention allocation were computed for each participant. A correlation analysis showed that the attentional probe index and the emotional Stroop index were associated within each presentation mode while all other relations were nonsignificant. These results are discussed in terms of a distinction between preattentive and attentional process…
Exegesis and myths as methodologies of research in tourism
2013
Anthropology has given interesting paradigms to tourism-led research. From the role played by culture to the conflict between host and guest, anthropology has focused in mobility and tourism issues. Nonetheless, when we think in tourism we imagine an all-encompassing institution. There were many forms of tourism, each one enrooted in their own culture. Mythology and exegesis remind not only that other non-western forms of tourism are interesting to study but also how we can examine those cultural values that do not exist any longer. What this note of research sustains is that positivism monopolized in tourism fields some methods at the time pushing others to the periphery of knowledge, like…
Culture and odor categorization : agreement between cultures depends upon the odors
2003
This study evaluated the effect of culture on the relationship between psychological dimensions underlying odor perception and odor categorization. In a first experiment, French, Vietnamese and American participants rated several perceptual dimensions of everyday odorants, and sorted these odorants on the basis of their similarity. Results showed that the three groups of participants differed in their perceptual judgments but agreed in categorizing the odors into four consensual groups (floral, sweet, bad, and nature). Three dimensions––pleasantness, edibility, cosmetic acceptability––discriminated these groups in the same way in the three countries. In a second experiment, the participants…
Graphemic complexity and multiple print-to-sound associations in visual word recognition
2005
Max Planck Institute for Psycholinguistics, Nijmegen, The Netherlands It has recently been reported that words containing a multiletter grapheme are processed slower than are words composed of single-letter graphemes (Rastle & Coltheart, 1998; Rey, Jacobs, Schmidt-Weigand, & Ziegler, 1998). In the present study, using a perceptual identification task, we found in Experiment 1 that this graphemic complexity effect can be observed while controlling for multiple print-to-sound associations, indexed by regularity or consistency. In Experiment 2, we obtained cumulative effects of graphemic complexity and regularity. These effects were replicated in Experiment 3 in a naming task. Overall, these r…
Quantum memories with zero-energy Majorana modes and experimental constraints
2016
In this work we address the problem of realizing a reliable quantum memory based on zero-energy Majorana modes in the presence of experimental constraints on the operations aimed at recovering the information. In particular, we characterize the best recovery operation acting only on the zero-energy Majorana modes and the memory fidelity that can be therewith achieved. In order to understand the effect of such restriction, we discuss two examples of noise models acting on the topological system and compare the amount of information that can be recovered by accessing either the whole system, or the zero-modes only, with particular attention to the scaling with the size of the system and the e…
Effects of Intranasal Oxytocin on Emotion Regulation in Insecure Adolescents: Study Protocol for a Double-Blind, Randomized Controlled Trial
2016
Background: Emotional dysregulation and impaired attachment are potential contributors to the development of psychopathology in adolescence. This raises the question of whether oxytocin (OT), the paradigmatic “attachment hormone,” may be beneficial in such contexts. Recent evidence suggests that intranasal administration of OT increases affiliative behavior, including trust and empathy. OT may also facilitate social reciprocity by attenuating the stress response to interpersonal conflict. To date, few studies have investigated the effects of intranasal oxytocin (IN-OT) on neurophysiological emotion regulation strategies in healthy adolescents, particularly during parent-adolescent interacti…
