“You Are Safe Now”: Migrant Youth Constructions of Safety and Schooling in the U.S.

open access: yesAnthropology &Education Quarterly, Volume 57, Issue 1, March 2026.
ABSTRACT Drawing on multisited ethnographic research with migrant families from Brazil, El Salvador, Guatemala, and Honduras who were detained, separated, or endured prolonged transit due to US immigration policies, we articulate how ideas of “relational safety” are situated in relationships with people, place, and time. Contrasting abundant literature

Automatic instantiation of abstract tests to specific configurations for large critical control systems [PDF]

open access: yes, 2009
Computer-based control systems have grown in size, complexity, distribution and criticality. In this paper a methodology is presented to perform an ‘abstract testing’ of such large control systems in an efficient way: an abstract test is specified ...

Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya

open access: yesAmerican Anthropologist, Volume 128, Issue 1, Page 183-194, March 2026.
ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.

Springboards Before the Fence: Urban Makeshift Camps as Mobility Infrastructures on the Bosnia–Croatia Border

open access: yesAntipode, Volume 58, Issue 2, 2026.
Abstract This paper frames migrant makeshift camps as mobility infrastructures, bridging scholarship on informal dwellings and migration infrastructures with the case of Bihać, a transit city on the Bosnia–Croatia border. The central idea is that grassroots makeshift camps assembled in abandoned buildings or tents play a key infrastructural role in ...

African Decolonial Theory: A Conversation

open access: yesAntipode, Volume 58, Issue 2, 2026.
Abstract Antipode has become a key platform for engaging with decolonial and anticolonial scholarship, as well as adjacent fields such as Black geographies, Indigenous studies, Latin American feminism, and work on settler‐colonialism. African reference points in this literature, however, have been far less common, both in the journal and more broadly ...
