Although culture contact is a well-studied area of archaeological inquiry, complex ancient cross-cultural interactions can be challenging to discern. As zones of innovation in which boundaries are obscure, ancient frontiers offer ideal contexts to analyze the nuances of such interactions. To address the challenges of interpreting a multicultural frontier in the Moquegua Valley, southern Peru, we apply a practice-based approach using foodways to elucidate the complexity of culture contact between Wari-affiliated and Indigenous Huaracane communities during the Middle Horizon (AD 600–1000). Our findings indicate that after Wari colonization of the Moquegua frontier, the Huaracane community at Yahuay Alta began brewing chicha de molle, an alcoholic beverage associated with and central to Wari political and religious social structures. They did not, however, adopt the practice in a completely Wari fashion. Instead, we see Huaracane leaders brewed and served chicha de molle in ways that aligned with their own cultural practices. The material remains of chicha de molle production and consumption at Yahuay Alta should not be seen as a simple adoption of a nonlocal cultural practice by an Indigenous group, but instead an active manipulation of practice as part of frontier cultural negotiations and entanglements.
Turbulence exhibits a striking duality: it drives concentrated substances apart, enhancing mixing and transport, while simultaneously drawing particles and bubbles into collisions. Little experimental data exist to clarify the latter process due to challenges in techniques for resolving bubble pairs from afar to coalescence via turbulent entrainment, film drainage and rupture. In this work, we tracked pairs of bubbles across nearly four orders of magnitude in spatial resolution, capturing the entire dynamics of collision and coalescence. The resulting statistics show that critical variables exhibit scalings with bubble size in ways that are different from some classical models, which were developed based on assumptions that bubble collision and coalescence only mirror the key scales of the surrounding turbulence. Furthermore, contrary to classical models which suggest that coalescence favours slow collision velocity, we find a ‘Goldilocks zone’ of relative velocities for bubble coalescence, where there is an optimal coalescence velocity that is neither too high nor too low. This zone arises from the competition between bubble–bubble and bubble–eddy interactions. Incorporating this zone into the new model yields excellent agreement with experimental results, laying a foundation for better predictions for many multiphase flow systems.
Demographic changes in rates of living alone, migration, and having no living partner, spouse, or children are leaving more older adults without the typical uncompensated familial and non-familial care partners that are the backbone of long-term care provision. We aimed to understand the precarities and outcomes specifically experienced by older adults without care partners to inform future intervention development. Using the Joanna Briggs Institute guidelines and PRISMA-ScR protocol, we conducted a scoping review of nine databases to map the current peer-reviewed evidence regarding these indivdiduals’ precarities, outcomes, and interventions using the Health Equity Promotion Model (HEPM) as our guiding framework. Our comprehensive search strategy resulted in 5,100 unique articles, 33 of which met our inclusion criteria. Three independent reviewers screened and extracted data, and the first author used deductive content analysis with the pre-specified HEPM framework. Fifteen studies reported precarities related to environmental/structural forces, and psychological, social, behavioral, and biological processes. Twenty-four studies reported adverse health and well-being outcomes with more focus on health than well-being outcomes (19 versus 8). Four studies tested interventions, and reported environmental/structural, social, and behavioral processes and health and well-being outcomes. Only 13 of the 33 reviewed studies set out to explicitly study older adults without care partners, and no studies focused on marginalized sub-groups. This scoping review highlights our lack of understanding of older adults without care partners’ distinctive precarities and outcomes, and the vital research needed to develop and test interventions that effectively address their unique needs.
El objetivo del trabajo es analizar la relación entre humanos y animales a lo largo del tiempo. En este contexto, buscamos puntualmente comprender el papel de estos últimos en los procesos de construcción identitaria de los grupos humanos de Sierras Centrales (Córdoba, centro de Argentina). Para ello, proponemos una perspectiva que integre herramientas metodológicas de la etnozoología, la historia y la arqueología. Desde el presente, abordamos el conocimiento ecológico local de las comunidades rurales, donde muchas familias llevan como apelativo el nombre de algún animal. En tanto, indagamos en los vínculos identificados en los documentos y trabajos históricos, lo que habilita rastrear cambios y continuidades de algunas prácticas sociales donde fueron mencionados los animales. Consideramos que la conjunción de estas líneas posibilita repensar la presencia de estos seres en las dinámicas sociales de las comunidades humanas del período Tardío (ca. 700-1550 dC), con base en el análisis de la iconografía zoomorfa del arte rupestre. La evidencia recuperada nos habilita a reconocer la continuidad del diálogo entre personas y animales como central en las dinámicas sociales, y cómo sus diferentes expresiones identitarias tuvieron lugar en distintos momentos históricos en las regiones objeto de estudio.
Studying Arik Shapira’s 1982/2003 opera Aqedah (Binding), this article probes the boundaries of Shapira’s resistance to the Zionist ideological apparatus. Having set the banishment of Ishmael (Genesis 21) side by side with the binding of Isaac (Genesis 22), Shapira highlighted the intricate network of correspondences between these two stories while restoring balance to Jewish victimhood, which usually excluded Ishmael in favour of politically actualising Isaac. To reflect the brutality embedded in these biblical stories (nationally appropriated or not), Shapira disintegrated the text into syllables to which he assigned mostly even durations and inert pitches; the result was a deliberately unemotional and stringent reportage, whose violent conveyance equalled its desemanticisation. Shapira’s use of musical and textual ready-mades in the third movement of Aqedah is situated here alongside an oratorio that reverences similar ready-mades, and in so doing affirms the nationalisation of the Holocaust (Noam Sheriff’s The Revival of the Dead), and a poem by Yizhak Laor, which marks a dialectical threshold Shapira could never cross. Despite his ensnarement, Shapira’s almost vandalistic approach signalled the separation of art music from territorial nationalism.
