This article explores the paradigm of collaborative economy, analyzing its possibledefinitions, limitations and contradictions of work in the contemporary world. In addition,we offer a contextual analysis of global forces and local impacts, based on life stories ofdriver-partners of the private transportation company Uber.

To better place the reader, it will be necessary to point out that the central core of his book addresses the perverse and contradictory side of globalization. However, it must be prevented, because you will not find here a hegemonic version of the subject, usually conceived as something abstract and omnipresent of forces. The author develops a rigorous sociology and does not trust any kind of canon, academic or theoretical fashion. On the contrary, his work is aimed at questioning the role of what he has called "master categories", noting their ability to illuminate and dull, placing certain aspects of reality in the shadow.

Glacial bodies in the Peruvian Andes Mountains store and supply freshwater to hundreds of thousands of people in central Peru. Atmospheric black carbon (BC) is known to accelerate melting of snow and ice, in addition to contributing to air pollution and the health of people. Currently there is limited understanding on the sources and temporal variability of BC in valley and mountain environments in Peru. To address this problem, this study combined surface observations of BC collected during 2022–2023 with WRF model simulations and HYSPLIT trajectories to analyze the dispersion and sources of BC in valley and high elevation environments and the associated local atmospheric circulations. Results show high BC concentrations are associated with the valley-mountain wind system that occurs on both sides of the Huaytapallana mountain range. A pronounced circulation occurs on the western slop...
