“De la mà de un florentí” y “De mestre Marçal”. Los dibujos del pintor valenciano Joan Moreno (1382-1448) y el cuaderno de los Uffizi

2020

A partir de la localización del testamento, inventario de bienes y almonedas posteriores tras el fallecimiento del pintor Joan Moreno en la ciudad de Valencia en 1448, se analiza la importancia del dibujo en los talleres del gótico internacional. La mención específica de dibujos del alemán Marçal de Sas (†1410) y de un florentino que podría ser Gherardo Starnina (c. 1354-1409-13) ofrece la posibilidad de analizar esta documentación en relación con el cuaderno de dibujos de los Uffizi (inv. 2264F-2281F, 18304F-18306F, 18324). Un repertorio de dibujos que se considera realizado en torno a los años 1400 en la ciudad de Valencia y que responde precisamente a las dos corrientes más importantes s…

La validación transcultural de intervenciones clínicas basadas en evidencia para el tratamiento de trastornos de ansiedad

2014

Las aplicaciones de tecnologías avanzadas han generado la emergencia de un espacio de investigación en ciencias del comportamiento. El creciente acervo de publicaciones, sobre la eficacia y eficiencia de programas de intervención para una serie de trastornos psicológicos, plan- tea la necesidad de fortalecerlos, evaluando su generalización a otros contextos culturales para contribuir a la medición de la validez externa. Mediante la colaboración de dos grupos de investi- gación, se realizó la validación transcultural de tres intervenciones empleando realidad virtual para el tratamiento de miedo a volar, agorafobia y miedo a hablar en público con un programa auto-apli- cado, que demostraron p…

Denying the Truth Does Not Change the Facts: A Systematic Analysis of Pseudoscientific Denial of Complex Regional Pain Syndrome

2021

Purpose Several articles have claimed that complex regional pain syndrome (CRPS) does not exist. Although a minority view, it is important to understand the arguments presented in these articles. We conducted a systematic literature search to evaluate the methodological quality of articles that claim CRPS does not exist. We then examined and refuted the arguments supporting this claim using up-to-date scientific literature on CRPS. Methods A systematic search was conducted in MEDLINE, EMBASE and Cochrane CENTRAL databases. Inclusion criteria for articles were (a) a claim made that CRPS does not exist or that CRPS is not a distinct diagnostic entity and (b) support of these claims with subse…

Do Older Employees Suffer More from Work Intensification and Other Intensified Job Demands? Evidence from Upper White-Collar Workers

2019

Background: Working life today is characterized by acceleration and intensification due to social, and particularly technological, acceleration affecting the whole of society. These phenomena also affect working life by intensifying job demands, possibly imposing new job stressors on the workforce. At the same time workforce is aging, raising a question how older employees manage to cope with these work life changes. Methods: This study examined intensified job demands and their effects on occupational well-being from the age perspective utilizing Finnish survey data from upper white-collar workers (N = 2,200). Data was analyzed using multivariate analysis of covariance and hierarchical reg…

Noninvasive neurostimulation methods for migraine therapy: The available evidence.

2016

Background Migraine is one of the most disabling neurological disorders. The current pharmacological armamentarium is not satisfying for a large proportion of patients because the responder rate does not exceed 50% on average and the most effective drugs often induce intolerable side effects. During recent years, noninvasive central and peripheral neuromodulation methods have been explored for migraine treatment. Overview A review of the available evidence suggests that noninvasive neuromodulation techniques could be beneficial for migraine patients. The transcranial stimulation methods allow modulating selectively cortical activity and can thus be curtailed to the patient’s pathophysiologi…

International Assessment Surveys of Educational Achievement in Developing Countries : Why Education Economists Should Care

2015

International audience; This paper reviews the most known international assessment studies that are conducted in the context of poor countries and highlights the lack of empirical evidence on the degree to which the contents of the tests really match countries' curricula. To illustrate, the paper evaluates the sensitivity of an international testing instrument by comparing the responses of students in two consecutive grades on the same battery of tests. Using propensity score matching to control for student and teacher characteristics, the results show that the tests are not grade sensitive, which raises the question of the validity of many empirical works that are based on similar instrume…

When more is less: The other side of artificial intelligence recommendation

2022

Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and with lower cost. Critics deem that consumers are more easily trapped in information cocoons because of the use of AI recommendation. This reduces the possibility of consumers contacting with a variety of commodities, thus lowering the consumer decision quality. Based on experiments, this paper discusses the moderating role of AI recommendation on the relationship of consumers' preferences and information cocoons. …

Systems Approaches in the Enterprise Architecture Field of Research: A Systematic Literature Review

2018

This study explores the use of the systems approaches (systems thinking and systems theories) as the theoretical underpinnings for Enterprise Architecture (EA) research. Both the academic and the practitioner communities have maintained an interest in EA due to its potential benefits, promising for the recent technological and business advances. EA as a research area is, however, characterized by diversified views depicted in different definitions of the concept, and no acknowledged common theoretical foundation. A number of prior studies have noticed this gap in the EA field of research, and called for a strengthening of the theory of EA. Variegated systems approaches have been suggested a…
