RESUMO
OBJECTIVES: Ageism is a prevalent, insidious social justice issue that has harmful effects on the health of older adults. Preliminary literature explores the intersectionality of ageism with sexism, ableism, and ageism experienced among LGBTQ+ older adults. Yet, the intersectionality of ageism with racism remains largely absent from the literature. Therefore, this study explores the lived experience of the intersectionality of ageism and racism among older adults. METHODS: This qualitative study applied a phenomenological approach. Twenty participants 60+ years of age (M = 69, standard deviation = 8.84) in the U.S. Mountain West identifying as Black, Latino(a), Asian-American/Pacific Islander, Indigenous, or White engaged in a 1-hr interview between February and July 2021. A 3-cycle coding process applied constant comparison methods. Five coders independently coded interviews, engaging in critical discussion to resolve disagreements. An audit trail, member checking, and peer debriefing enhanced credibility. RESULTS: This study focuses on individual-level experiences exemplified by 3 umbrella themes and 7 subthemes. The subthemes are (a) compounding oppression, (b) intersection of disparities, (c) White privilege, (d) racism and ageism: being tokenized or ignored, (e) ageism and racism: unspoken bias, (f) racism versus ageism: overt or covert? and (g) racism versus ageism: differentiated or ubiquitous? DISCUSSION: The findings indicate how ageism may be racialized through stereotypes related to mental (in)capability. Practitioners can apply the findings to enhance support for older adults by designing interventions aimed at reducing racialized ageist stereotypes and increasing collaboration through education across anti-ageism/anti-racism initiatives. Future research should focus on the impacts of the intersectionality of ageism and racism on specific health outcomes in addition to structural-level interventions.

In this work, nitrogen-doped magnetic porous carbon material (N-MPC) was prepared through the high-temperature calcination of low-cost [Fe(CN)6]3--loaded anion-exchange resin, which was experimentally demonstrated to have significant adsorption performance for tetracycline (TC) in water. The N-MPC adsorbent with a large specific surface area (781.1 m2 g-1) was able to maintain excellent performance in a wide pH range from 4 to 10 or in high ionic strength solution. The adsorption of TC on N-MPC was found to be more consistent with the pseudo-second-order model and Langmuir adsorption model, and the maximum adsorption capacity (qm, cal) was calculated to be 603.4 mg g-1. As a recoverable magnetic adsorbent, the N-MPC remained a TC removal rate higher than 70% after four adsorption cycles. The adsorption mechanism was speculated on the basis of characterizations, where pore filling, hydrogen bonding interaction, and π-π electron donor-acceptor (EDA) interaction were crucial adsorption mechanisms. A variety of antibiotics were selected for adsorption, and excellent performance was found especially for TCs, indicating that the N-MPC can be used for the efficient removal of TCs from water.
