Multiple elements of soil biodiversity drive ecosystem functions across biomes
(NATURE PUBLISHING GROUP, 2020)
The role of soil biodiversity in regulating multiple ecosystem functions is poorly understood, limiting our ability to predict how soil biodiversity loss might affect human wellbeing and ecosystem sustainability. Here, ...
Using classical Cepheids to study the far side of the Milky Way disk: I. Spectroscopic classification and the metallicity gradient
(Chile. Universidad Mayor, 2020)
Context. Much of what we know about the Milky Way disk is based on studies of the solar vicinity. The structure, kinematics, and chemical composition of the far side of the Galactic disk, beyond the bulge, are still to be ...
Understanding How Much TV is Too Much: A Nonlinear Analysis of the Association Between Television Viewing Time and Adverse Health Outcomes
(Chile. Universidad Mayor, 2020)
Objective: To inform potential guideline development, we investigated nonlinear associations between television viewing time (TV time) and adverse health outcomes. Methods: From 2006 to 2010, 490,966 UK Biobank participants, ...
Why Let the Dogs Out? Exploring Variables Associated with Dog Confinement and General Characteristics of the Free-ranging Owned-Dog Population in a Peri-urban Area
(Chile. Universidad Mayor, 2020)
Free-ranging dogs (FRDs), are a problem in several countries, with impacts on humans, domestic animals, and wildlife, although increasing evidence suggests that most FRDs are owned. Therefore, understanding dog ownership ...
¿Cuál es la curva que mejor explica el crecimiento de los casos confirmados de COVID-19 en Chile?
(Chile. Universidad Mayor, 2020)
Objective: to explore the best type of curve or trend model that could explain the epidemiological behavior of the infection by COVID-19 and derive the possible causes that contribute to explain the corresponding model and ...
Varieties of Skills Profiles in Latin America: A Reassessment of the Hierarchical Model of Capitalism
(Chile. Universidad Mayor, 2020)
Research on the politics of skills formation in Latin America is severely underdeveloped. This article offers a novel characterisation of the supply of skills in the region or 'skills supply profiles', taking inspiration ...
Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells
(Chile. Universidad Mayor, 2020)
The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
Walking toward Metro Stations: the Contribution of Distance, Attitudes, and Perceived Built Environment
(Chile. Universidad Mayor, 2020)
Walking as an active means of travel is important as a sustainable mode of transport. Moreover, the level of walking in the surrounding areas of metro stations would contribute to maintaining the minimum rate of physical ...
Using Ecological Modelling to Assess the Long-Term Survival of the West-Indian Manatee (Trichechus manatus) in the Panama Canal
(Chile. Universidad Mayor, 2020)
There is evidence of a thriving population of West-Indian manatee (Trichechus manatus) in the Panama Canal, although it is not clear if they are descendants of a small group of introduced manatees or if manatees have entered ...
Two Centuries of Hydroclimatic Variability Reconstructed From Tree-Ring Records Over the Amazonian Andes of Peru
(Chile. Universidad Mayor, 2020)
Almost half of the tributaries of the Amazon River originate in the tropical Andes and support large populations in mountain regions and downstream areas. However, it is difficult to assess hydroclimatic conditions or to ...
