Endocrine Disruptors and Autism Spectrum Disorder in Pregnancy: A Review and Evaluation of the Quality of the Epidemiological Evidence
2018
Exposure to environmental contaminants during pregnancy has been linked to adverse health outcomes later in life. Notable among these pollutants are the endocrine disruptors chemicals (EDCs), which are ubiquitously present in the environment and they have been measured and quantified in the fetus. In this systematic review, our objective was to summarize the epidemiological research on the potential association between prenatal exposure to EDCs and Autism Spectrum Disorder (ASD) published from 2005 to 2016. The Navigation Guide Systematic Review Methodology was applied. A total of 17 studies met the inclusion criteria for this review, including: five cohorts and 12 case-control. According t…
La teoría del cambio: una herramienta para la planificación y la evaluación participativa en salud comunitaria
2020
Resumen: Existe un creciente interés por encontrar respuestas innovadoras para evaluar intervenciones complejas en salud pública. En esta nota metodológica, se presenta la teoría del cambio como una herramienta útil para facilitar tanto la planificación como la evaluación de intervenciones en promoción de la salud comunitaria. Una teoría del cambio es una representación visual de cómo funciona un programa o una intervención, en la que se identifican sus diferentes componentes y cómo cada elemento se vincula con otro: cuáles son sus objetivos, los resultados esperados y a través de qué acciones se pretenden alcanzar. Es una herramienta de investigación aplicada a la práctica que se desarroll…
Evaluating the statistical methodology of randomized trials on dentin hypersensitivity management
2017
The present study aimed to evaluate the characteristics and quality of statistical methodology used in clinical studies on dentin hypersensitivity management. An electronic search was performed for data published from 2009 to 2014 by using PubMed, Ovid/MEDLINE, and Cochrane Library databases. The primary search terms were used in combination. Eligibility criteria included randomized clinical trials that evaluated the efficacy of desensitizing agents in terms of reducing dentin hypersensitivity. A total of 40 studies were considered eligible for assessment of quality statistical methodology. The four main concerns identified were i) use of nonparametric tests in the presence of large samples…
Methodologies to study soil nitrogen Méthodes pour l'étude de l'azote dans le sol Metodologie per lo studio dell'azoto nel suolo
2011
Nitrogen (N) is a key element within terrestrial ecosystems and, thus, the whole knowledge of its transformation processes is crucial. Especially in soil, complex and heterogeneous system, N undergoes several transformations as it is indicated by its various oxidation states. Moreover, it mainly occurs under a number of organic forms, whose identification and quantification is still challenging. Here, we review some extraction methodologies of N from soil, but also the isotope dilution technique, which helps in assessing gross N mineralisation. Finally, we discuss the NanoSIMS technique, which shows a good potential for investigating soil N dynamics at nanoscale. Résumé L'azote (N) est un é…
Methodological approaches for the enhancement of cultural heritage
2012
The subject of this essay starts by considering how, in many cases, artificial lighting outlines such as finding an “impalpable material” which helps to understand and enhance the ancient contexts. In general, it was demonstrated that, combining innovative technologies, light can be used to change the world, to shape cities, as well as architecture and space in general. Light can turn into concrete matter both in interiors, in archaeological and urban spaces. There is the possibility to obtain a recovery of memory and identity of a city, in order to achieve efficiency and effectiveness of the results. Starting with an overview of experimental research methodology it is possible to define an…

The methods and techniques of the research on war and conflicts. The outline of the issue
2018
The aim of this paper is to present the methodological assumptions necessary to examine the wars and conflicts. Authors refer to the genesis of the research on the phenomenon of war that occurred after the end of World War II. Moreover, the authors selects the research methods. The wide range of research methods will be applied in international relations, such as an empirical report, based on the description of the various conflicts and their interpretation. It must be emphasized that methodological technique applied in humanities and empirical sciences is necessary to examine war and peace. Above all, two methods are the most important, that is, inductionism that allows to collect and logi…
The Subjective Social Value of Education Construct: CrossValidation between School and University Teachers
2016
La Educación posee un valor social evidente que puede presentarse mediante indicadores de evaluación socio-educativos. Si bien la relación entre contexto escolar y rendimiento es evidente en diversos países, esta relación va perdiendo consistencia en los últimos años; ya que aparecen sectores estudiantiles que superan las predicciones académicas esperadas. Para ello, se estudia el Valor Social Subjetivo de la Educación en función de dos grupos docentes –escuela y universidad–. La metodología es complementaria a través de comités de expertos/as y validación cruzada de constructo. Se realizan análisis sobre dos escalas –relevancia y susceptibilidad de cambio– y entre dos muestras diferenciada…
Journalisme numérique: théorie, méthodologie et critères d'analyse
2007
Comunicación presentada en el congreso de la International Association for Media & Communication Research (IAMCR) at UNESCO, Paris, 23-25 Juillet 2007. Dans cette communication, nous proposons une approche théorique et méthodologique pour l'analyse des contenus numériques. D'une part, nous établissons quelle est la typologie -et les critères qui vont la définir- de ces contenus et types cyberjournalistiques : (1) leur nature : (a) interactifs, (b) de communication interpersonnelle, (c) de participation des Communautés et (e) accès à l’information ; et (2) leur condition stratégique : (a) adaptés (versions d'autres formats existants, comme webs pour PDA), (b) d'anticipation (ex. alertes), (c…
