    • When is n large enough? Looking for the right sample size to estimate proportions 
      Canals, Catalina; Canals, Andrea (Taylor and Francis Ltd., 2019)
      The central limit theorem indicates that when the sample size goes to infinite, the sampling distribution of means tends to follow a normal distribution; it is the basis for the most usual confidence interval and sample ...

    • Are cursorial birds good kinematic models of non-avian theropods? 
      Grossi, Bruno; Loncomilla, Patricio; Canals Lambarri, Mauricio; Ruiz del Solar, Javier (Universidad de la Frontera, 2019)
      Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur ...

    • Elucidating viral communities during a phytoplankton bloom on the west Antarctic Peninsula 
      Alarcón Schumacher, Tomás; Guajardo Leiva, Sergio; Antón, Josefa; Díez, Beatriz (Frontiers Media, 2019)
      In Antarctic coastal waters where nutrient limitations are low, viruses are expected to play a major role in the regulation of bloom events. Despite this, research in viral identification and dynamics is scarce, with limited ...

    • Exporting and plant-level efficiency gains: It’s in the measure 
      Garcia-Marin, Alvaro; Voigtländer, Nico (University of Chicago Press, 2019)
      While there is strong evidence that more productive plants select into exporting, the literature has struggled to identify export-related efficiency gains within plants. We show that this is due to the common use of ...
