Arguing from the overall settlement plan and the form of buildings, the authors present a persuasive case that the Late Postclassic city of Tlaxcallan and its near neighbour Tizatlan constitute the central elements of a republican state. This is an unusual political prescription, not only in Mesoamerica but further afield.
Globally, farmworkers are among the most affected by the COVID-19 pandemic and its economic fallout. Longstanding social and spatial inequalities allowed COVID-19 to spread unchecked, propelling a surge in farmworker activism, while the state uses the crisis to rollback worker protections. The politics of this moment are rooted in racialized labor regimes characterized by "imported colonialism". We use the case of Florida, where farmworker movements have for decades organized for health and justice, to contribute to the global debate on COVID-19, and to show how a deep history of the present can illuminate opportunities and challenges for organizing.
Hotter summers caused by global warming and increased workload and duration are endangering the health of farmworkers, a high-risk population for heat-related illness (HRI), and deaths. Although prior studies using wearable sensors show the feasibility of employing field-collected data for HRI monitoring, existing devices still have limitations, such as data loss from motion artifacts, device discomfort from rigid electronics, difficulties with administering ingestible sensors, and low temporal resolution. Here, this paper introduces a wireless, wearable bioelectronic system with functionalities for continuous monitoring of skin temperature, electrocardiograms (ECG), heart rates (HR), and activities, configured in a single integrated package. Advanced nanomanufacturing based on laser machining allows rapid device fabrication and direct incorporation of sensors with a highly breathable substrate, allowing for managing excessive sweating and multimodal stresses. To validate the device's performance in agricultural settings, the device is applied to multiple farmworkers at various operations, including fernery, nursery, and crop. The accurate data recording, including high-fidelity ECG (signal-to-noise ratio: >20 dB), accurate HR (r = 0.89, r 2 = 0.65 in linear correlation), and reliable temperature/activity, confirms the device's capability for multiparameter health monitoring of farmworkers.
Agricultural workers, designated as “essential” at the start of the COVID-19 pandemic, work in harsh labor conditions, and now have the added challenge of continuing to work during the COVID-19 pandemic. The aim of this study was to assess agricultural workers’ COVID-19 related history, employer-based safety measures, individual preventive practices, and COVID-19 vaccination uptake. A questionnaire study was conducted among agricultural workers in Central Florida about COVID-19 during the month of June 2020 and again in July 2021. Among 92 agricultural workers in June 2020, 47% were obese; 11% had had a COVID-19 nasal test; 87% were able to social distance at work and 34% reported employer provided face masks; 15% reported not willing to get the COVID-19 vaccine and 25% were unsure. 40% could self-isolate if they contracted COVID-19. In a follow-up visit in July 2021, 53% of participants reported receiving a COVID-19 vaccine. Agricultural workers are particularly vulnerable to COVID-19 due to existing health risk factors and lack of essential protective resources. Occupational health protections social safety net programs are urgently needed to prevent infections in vulnerable workers, and reduce community spread, and increase COVID-19 vaccination rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
