State Integration and Violence at the Margins: The Logic of Police Raids in Rio de Janeiro's Favelas

The Howard Journal of Crime and Justice, EarlyView.
ABSTRACT This paper investigates police raids in Rio de Janeiro's favelas through a property rights framework, exploring their organisational structure, motivations and implications. Using data from police reports, academic studies, NGOs and news sources, it examines why and how the state intervenes in these contested spaces.

A Comparative Study between M30 and M92: M92 is a Merger Remnant with a Large Helium Enhancement

The Astrophysical Journal
We perform a comparative study of the ex situ second-parameter pair globular clusters (GCs) M30 and M92, having similar metallicities but different horizontal branch morphologies.

Boniteza's Arts Chair, Pedagogical Curatorial Practices with Contemporary Artists as Arts‐Based Educational Research

International Journal of Art &Design Education, EarlyView.
Abstract This article puts forward a new methodology in artistic education. It is based on scientific utopia as it aims for the implementation in schools of the cátedras de la Boniteza (the Boniteza's Art Chair), where an inhabiting artist changes the institution from within through the development of quality art projects.

On the Age Calibration of Open Clusters Using Red Clump Stars

The Astronomical Journal
In this study, we extend the dust-independent Hatzidimitriou relation between cluster age and d _B _− _R color difference between the red giant branch (RGB) and red clump to younger cluster ages.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Anomalously Fast Core and Envelope Rotation in Red Giants

The Astrophysical Journal
Red giants undergo dramatic and complex structural transformations as they evolve. Angular momentum is transported between the core and envelope during this epoch, a poorly understood process.
