We gather and process street-name data from OpenStreetMap to create an accessible and readily analyzable street names database for the US and a large part of Europe. We also develop a web app to visualize the spatial distribution of street names and download the underlying data from users’ queries. These tools will continue to expand its geographic coverage by including additional countries.

Given the impossibility of empirically studying their impact on real-world conditions, clinical vignettes were developed with the goal of identifying the use of heuristics in the care of critically ill patients during the COVID-19 pandemic in different clinical contexts. Methodology: Vignettes were designed by critical care physicians in Spain to assess the use of representativeness, availability, and status quo heuristics in the care of critically ill patients during the COVID-19 pandemic. The construct, internal and external validity of the vignettes designed in Spain, the United States and Chile were evaluated. A questionnaire was piloted with the vignettes being validated in the three aforementioned countries through a computer application built for this purpose. Results 16 study vignettes grouped into 5 models were created...

No obstante, la valoracion de los usuarios puede estar modulada por sesgos ideologicos. Se sostiene que cuanta mayor es la distancia entre la orientacion ideologica del individuo y la del gobierno, ambas expresadas en una escala de 1 a 10, menor sera la satisfaccion. Se utilizan datos del Barometro Sanitario 2010-2013 y se elabora un modelo multinivel de regresion lineal para testar la asociacion entre ambas variables. Se incluyen en el modelo otras variables de interes, como el gasto publico sanitario y la nacionalidad. Se concluye que existe una relacion negativa entre la distancia ideologica y la satisfaccion. El gasto sanitario per capita esta asociado con la satisfaccion, pero el esfuerzo que ello supone para cada region no es significativo, mientras que los espanoles tienen un nivel de satisfaccion considerablemente menor que los extranjeros.

First, we motivate the relevance of street-name data for researchers in social sciences. Second, we describe the data sources employed as well as the data cleaning process. Third, we present a web search app that allows to spatially visualize and download street-name data for Spain, with a time coverage spanning from 2001 to 2022
