Understanding clerical decisions in granting social assistance: Insights from national social security officials in Brazil

open access: yesInternational Social Security Review, Volume 78, Issue 1, Page 29-56, January/March 2025.
Abstract Street‐level professionals, such as social workers, shape policy implementation by exerting discretion. However, it remains unclear how other street‐level bureaucrats (SLBs), who are not considered to hold a professional status and who perform highly regulated activities, can do the same. Even though the decision‐making leeway of these SLBs is

Cameras or Camus? Comparing Snow Track Surveys and Camera Traps to Estimate Densities of Unmarked Wildlife Populations

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
Waller et al. used camera traps to estimate the densities of four ungulate species in the Russian Far East and compared these estimates with those from the traditional Formozov snow tracking approach. The authors found that both approaches can provide consistent estimates of population density, but the time and resource demands of snow tracking were ...

Basic income as a pandemic social protection instrument: Lessons from Maricá, Brazil

open access: yesInternational Social Security Review, Volume 77, Issue 1-2, Page 121-136, January-June 2024.
Abstract This article explores the connection between two related but distinct models of basic income proposals in the context of a pandemic emergency. While COVID‐19 appears to have increased interest in basic income, this often ended up taking the form of a temporary emergency basic income (EBI) instead of a permanent universal basic income (UBI). In
