An Upside-Down Humanism for the Anthropocene
(Philosophy and Global Affairs) Singh, Preeti
While thinkers such as Frantz Fanon, Edward Said, and Sylvia Wynter have criticized Enlightenment humanism for its embeddedness in coloniality, they also call for a refashioned humanism that expands the notion of the human while centering the agency of the oppressed. The author places these engagements in conversation with indigenous thought that challenges not only traditional humanism for its dehumanization of the non-Western, non-male subject but also humanist discourses of national liberation that reify these exclusions. Through its focus on literary writing and activism based in the resource-rich territory of Bastar in Central India, this article examines the separation of the human and the non-human that undergirds the Anthropocene, challenged in Adivasi-indigenous territories on the periphery of the nation-state, where extractive capitalism has rendered “inhuman” the bodies that fall outside discourses of national sovereignty. The author proposes an “Upside-down Humanism” for framing discourses of knowledge and modes of representation that center the entangled histories of the human and the non-human in worlds turned upside-down by extractive state-capitalism in the era of the Anthropocene.

Contributions of Gray Matter Microstructure to Differences in Fluid Cognition and Episodic Memory Across the Healthy Adult Lifespan.
(Human brain mapping, 2026-04) Merenstein, Jenna L; Bennett, Ilana J; Madden, David J
Cognitive decline, in healthy older adults without cognitive impairment or dementia, has been associated with numerous microstructural alterations in brain tissue using magnetic resonance imaging (MRI). Prior studies have primarily linked age-related cognitive decline to alterations in white matter tissue, but methodological advances in diffusion-weighted imaging (dMRI) data acquisition and modeling now allow for these analyses to be extended to gray matter tissue. Here, using a sample of 152 healthy adults (18-88 years of age), we used a multicompartment dMRI model to assess (1) age-related differences in gray matter microstructure of functionally defined networks and (2) whether microstructural alterations accounted for age-related differences in episodic memory and speed-dependent fluid cognition. We observed significant age-related alterations in gray matter tissue in the form of nonlinear, age-related increases and decreases in intracellular and dispersed diffusion, respectively, and linear increases in free diffusion. Free diffusion exhibited the most pronounced age-related effects, especially for frontoparietal relative to occipital regions. Dispersed diffusion in the dorsal attention network statistically mediated age-related differences in episodic memory performance. Moreover, higher intracellular diffusion in the default mode and ventral attention networks was related to worse fluid cognition performance, but only for adults > 51 years of age. These results suggest that healthy aging is accompanied by distinct profiles of gray matter microstructural alterations that negatively affect memory and speed-dependent cognition, the latter of which is more pronounced after midlife.

Intersectional Medical Mistrust: Addressing Knowledge Gaps in Healthcare Research
(2025) Matengula, Okoma Atani
This thesis explores quantitative research on medical mistrust and the minority patient-provider relationship in the United States. As a result of historical medical abuses against Black bodies, Black communities within the U.S. have lost trust in healthcare institutions and medical providers. These abuses such as the Tuskegee study and Norplant regulations have had a major negative impact on the patient-provider relationship between minority communities and healthcare professionals. Some research has employed quantitative ethnographic research methods in order to understand the culture within medical institutions. Overall, research into this relationship has shown a correlation between racism, adverse health outcomes, and minority experiences with healthcare providers but has failed to identify the key contributing factors to modern day minority mistrust in healthcare institutions. I suggest applying an intersectional lens to ethnographic medical research on minority populations, specifically minority pregnant individuals to fully understand the role of care institutions in perpetuating maternal health disparities and their impact on the relationship between patients and providers. The paper aims to clearly identify the relationship between obstetric racism and negative health outcomes for minority pregnant individuals by addressing the culture of care within healthcare spaces. This thesis first reviews and analyzes the literature on medical mistrust and healthcare disparities. Then this paper discusses medical ethnography, its uses, methods, and the subsequent gaps in the literature on medical mistrust. Chapter Three discusses research recommendations on how to fill the gaps in literature using longitudinal intersectional ethnographic methods in medical research. Chapter Four discusses the limitations of longitudinal ethnographic research methods. Chapter Five discusses the future of medical institutions and medical research.
