Migrating to stay or commuting to work? How fairness perceptions and exposure shape attitudes toward labor migration

American Journal of Political Science, EarlyView.
Abstract Existing literature posits that attitudes toward immigration are shaped by the impact of migrants on native workers' wages and employment, as well as by various other material, cultural, and social concerns. However, empirically disentangling these influences can be challenging.

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

Archaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Common Pressures, Uneven Trajectories: The Variegated Europeanisation of Wage Regulation Institutions

British Journal of Industrial Relations, EarlyView.
ABSTRACT The debate on whether national industrial relations (IR) are experiencing convergence is a long‐standing one. Recently, scholars argue that we are witnessing a neoliberal convergence of national IR, understood as an increase in employers’ discretion.
