Racial exclusion causes acute cortisol release among emerging-adult African Americans: The role of reduced perceived control
Get PDFRacial discrimination contributes to stress-related health disparities among African Americans, but less is known about the acute effects of racial exclusion on the hypo-pituitary-adrenocortical response and psychological mediators. Participants were 276 Black/African American emerging-adults (54% female; M age = 21.74, SD = 2.21) who were randomly assigned to be excluded or included by White peers via the game Cyberball. Racial exclusion (vs. inclusion) predicted: greater negative affect (F(1, 276) = 104.885, p \u3c .0001), lower perceived control (F(1, 276) = 205.523, p \u3c .0001), and greater cortisol release (F(1, 274) = 4.575, p = .033). Racial exclusion’s impact on cortisol release was mediated by lower perceived control (95% CI: .027, .112), but not negative affect (−.041, .013). These findings suggest that racial exclusion contributes to acute cortisol release, and that reduced perceived control is a consequence of racial discrimination that has important implications for the health of those who experience discrimination
Loss of foundation species revisited: conceptual framework with lessons learned from eastern hemlock and whitebark pine
Get PDFEcologists and conservation biologists often prioritize the study of species that are declining, threatened, or endangered over species that are abundant and ecologically important, such as foundation species (FS ). Because entire ecosystems and their biodiversity depend on FS , we argue that they have high conservation priority. A citation analysis reveals that FS are studied, but often are characterized ambiguously. More effort is needed to identify FS before they, and the ecosystems they define, are at risk of decline or loss. We suggest a new conceptual framework that includes: informed identification of FS in ecosystems; documentation of ecosystem services provided by FS ; a long‐term monitoring strategy to detect threats to FS within specified ecosystems; and, if threats are identified, a comprehensive conservation and adaptive management strategy for FS . We use two widely distributed, rapidly declining North American foundation tree species (Tsuga canadensis [eastern hemlock] and Pinus albicaulis [whitebark pine]) to illustrate this framework. These species exemplify the importance of identifying FS early and conserving or restoring them when they are threatened

Get PDFDyeing the Springtime: The Art and Poetry of Fleeting Textile Colors in Medieval and Early Modern South Asia
Get PDFThis paper explores the metaphorical and material significance of short-lived fabric dyes in medieval and early modern South Asian art, literature, and religious practice. It explores dyers’ manuals, paintings, textiles, and mercantile and devotional poetry to demonstrate how the existence of ephemeral dyes opened up possibilities for mutability that cannot be found within more stable, mineral pigments, set down on paper in painting. While the relationship between the image and the word in South Asian art is most often mutually enhancing, the relationship between words and color, and particularly between poetry and dye color, operates on a much more slippery basis. In the visual and literary arts of South Asia, dye colors offered textile artists and poets alike a palette of vibrant hues and a way to capture shifts in emotions and modes of devotion that retained a sense of impermanence. More broadly, these fragile, fleeting dye materials reaffirm the importance of tracing the local and regional histories even of objects, like textiles, that circulated globally
Universality and Modeling Limiting Behaviors
Get PDFMost attempts to justify the use of idealized models to explain
appeal to the accuracy of the model with respect to difference-making causes.
In this paper, I argue for an alternative way to justify using idealized models
to explain that appeals to universality classes. In support of this view, I show
that scientific modelers seeking to explain stable limiting behaviors often
explicitly appeal to universality classes in order to justify their use of idealized
models to explain
