Newborn infants' auditory system is sensitive to Western music chord categories
2013
Neural encoding of abstract rules in the audition of newborn infants has been recently demonstrated in several studies using event-related potentials (ERPs). In the present study the neural encoding of Western music chords was investigated in newborn infants. Using ERPs, we examined whether the categorizations of major vs. minor and consonance vs. dissonance are present at the level of the change-related mismatch response (MMR). Using an oddball paradigm, root minor, dissonant and inverted major chords were presented in a context of consonant root major chords. The chords were transposed to several different frequency levels, so that the deviant chords did not include a physically deviant f…
La Carta sociale europea come parametro interposto nella recente giurisprudenza costituzionale: novità e questioni aperte
2019
In two judgments delivered in 2018 (No. 120 and No. 194), the Constitutional Court for the first time referred to provisions of the European Social Charter as an interposed norm in the constitutional review of primary laws. The two judgments, however, leave two questions open. First, in judgment No. 120, the Court recognizes taht the European Social Charter may complement Article 117, paragraph 1, of the Constitution, as it constitutes a natural integration of the European Conventionof Human Rights on the social level, which in fact distinguishes it from "ordinary" international agreements. In its subsequent judgment No. 194, on the other hand, the Court speaks of treaties with constitution…
Contrast perception in digitized panoramic radiographs compared with their film-based origin
2002
Abstract Objectives. We sought to compare the visual image quality of film-based and digitized panoramic radiographs through use of a hole-containing test wedge. Study Design. An aluminum wedge containing 100 cells, of which 90 were given shallow holes, was exposed in the film-based Orthophos CD panoramic unit. Two radiographs subjectively exhibiting optimum contrast were selected. Films were digitized with a charge-coupled device flatbed scanner at 300 dpi. Films and digitized images were rated cellwise by 2 similar groups of 50 observers each with respect to spot perception. Results. The mean sensitivity was 0.26 ± 0.09 for film and 0.20 ± 0.07 for digitized images (P =.000), with a prono…
Probabilistic interpretation of the Calderón problem
2017
In this paper, we use the theory of symmetric Dirichlet forms to give a probabilistic interpretation of Calderon's inverse conductivity problem in terms of reflecting diffusion processes and their corresponding boundary trace processes. This probabilistic interpretation comes in three equivalent formulations which open up novel perspectives on the classical question of unique determinability of conductivities from boundary data. We aim to make this work accessible to both readers with a background in stochastic process theory as well as researchers working on deterministic methods in inverse problems.
El diálogo entre la Corte Interamericana de Derechos Humanos, los Tribunales Constitucionales de la Región Andina y el Tribunal Europeo de Derechos H…
2015
La comunicación entre tribunales, posibilita la existencia de un intercambio de ideas sobre lo que se debe entender por el contenido de un derecho o de una garantía, con la tendencia de otorgarse mayor protección a favor del ser humano; diálogo que no implica la existencia del predominio de una jurisdicción (internacional o estatal) sobre otra, al contrario con las interrelaciones que se producen entre tribunales, lo que se busca es lograr convergencias interpretativas que propicien un entendimiento común de los derechos y de las garantías. Se ha elegido para trabajar algunas garantías y derechos, como son el plazo razonable, juez natural, libertad de pensamiento-expresión e información- e …
Introduction: Time, Space and Economics in the History of Latin America
2020
This book represents a contribution in, at least, three dimensions: quantitative, historical and conceptual. From a quantitative point of view, the volume presents an extensive data set corresponding to 9 countries, 182 regions (states, provinces, departments) and around 14 benchmark years from the end of the nineteenth century to the beginning of the twenty-first century. This constitutes a substantial contribution to quantitatively analyse the economic development of Latin America, identifying the evolution of regional inequality and studying economic convergence and the formation of convergence clubs (clusters of poor and rich regions). Second, the volume combines a regional and supranat…
Coping and parental role competence of mothers of preterm infant
2014
The study was aimed at obtaining knowledge about mothers' experiences of preterm birth. The objective of the study is to explore coping strategies and self- perceived parental competence, in mothers of infant born moderately and severely preterm and admitted to the Neonatal Intensive Care Unit (NICU). METHODS: The study involved a group of 16 mothers of moderately preterm children (weeks' gestational age: mean=34, SD=2 and birth weight: mean=2000 g, SD=200 g) and a group of 14 mothers of severely preterm children (weeks' gestational age: mean=29, SD=2 and birth weight: mean=1700 g, SD=350 g). The following instruments were used with mothers to investigate focus areas of research: Coping Ori…
Prevalence of anatomical variants and coronary anomalies in 543 consecutive patients studied with 64-slice CT coronary angiography
2008
The aim of our study was to assess the prevalence of variants and anomalies of the coronary artery tree in patients who underwent 64-slice computed tomography coronary angiography (CT-CA) for suspected or known coronary artery disease. A total of 543 patients (389 male, mean age 60.5 +/- 10.9) were reviewed for coronary artery variants and anomalies including post-processing tools. The majority of segments were identified according to the American Heart Association scheme. The coronary dominance pattern results were: right, 86.6%; left, 9.2%; balanced, 4.2%. The left main coronary artery had a mean length of 112 +/- 55 mm. The intermediate branch was present in the 21.9%. A variable number …
Rationale, design and methods of CTCA-PRORECAD (Computed Tomography Coronary Angiography Prognostic Registry for Coronary Artery Disease): a multicen…
2013
PURPOSE: This study was done to assess the prognostic value of computed tomography coronary angiography (CTCA) in a large multicentre population of patients with suspected coronary artery disease (CAD) and, in particular, its incremental value compared with traditional methods for risk stratification. MATERIALS AND METHODS: This is a retrospective observational study that began in January 2003 conducted on patients with suspected CAD assessed with CTCA on the basis of symptoms (chest pain, dyspnoea) and/or abnormal or equivocal stress test and/or a high cardiovascular risk profile. The participating centres will provide data obtained with CTCA performed with 16-slice or higher equipment. Ex…
Acceptance of noninvasive computed tomography coronary angiography: for a patient-friendly medicine.
2014
PURPOSE: This study was done to evaluate the psychological state and anxiety of patients undergoing computed tomography coronary angiography (CTCA), and assess their acceptance and satisfaction compared to invasive conventional coronary angiography (CCA). MATERIALS AND METHODS: A total of 442 consecutive patients (282 male; mean age 57.7 ± 9.5 years) who underwent CTCA for suspected or known coronary artery disease were evaluated with the Endler Multimodality Anxiety Scales (EMAS) before and after the scan, and a questionnaire administered after the scan. Among the 442 patients, 181 had a history of CCA. Two radiologists assessed the image quality of CTCA. RESULTS: Anxiety was more intense …
