Narratives and stories of an “anti-racist racist:” making whiteness visible, bridging the gap between the individual and systems of oppression

The central purpose of this research is to make whiteness visible, to help white students’ overcome resistance to and denial of racism, white privilege, and racial inequities in the classroom. This research uses autoethnography, as a methodological approach with an emphasis on an analysis of the interactions between individuals and institutions. This research draws upon the emphasis on institutions from “institutional ethnography.” The methodological approach is framed by letter writing with elements of the “storytelling project model” using personal narratives and composite stories from the classroom. The theoretical framework for this research incorporates various theories, including constructivism theory, standpoint theory, critical theory, critical race theory, and critical Whiteness theory. This research examines my lived experiences and reflections, in the context of institutional social relations with the application of theoretical analysis, which work to deconstruct my whiteness to produce an authentic and rich explanation of white resistance to and denial of racism. This research is about bridging the gap between the individual and structure in order to alter oppressive cycles, seeking to raise awareness and create a space for open dialogue on racism to promote a more socially just society

Which Cost Components Influence the Cost of Palliative Care in the Last Hospitalization? A Retrospective Analysis of Palliative Care vs. Usual Care at a Swiss University Hospital.

CONTEXT Although the number of studies on the economic impact of palliative care (PC) is growing, the great majority report costs from North America. OBJECTIVES We aimed to provide a comprehensive overview of PC hospital cost components from the perspective of a European mixed funded health care system by identifying cost drivers of PC and quantifying their effect on hospital costs compared to usual care (UC). METHODS We performed a retrospective, observational analysis examining cost data from the last hospitalization of patients who died at a large academic hospital in Switzerland comparing patients receiving PC versus UC. RESULTS Total hospital costs were similar in PC and UC with a mean difference of CHF -2'777 [95% confidence interval (CI) -12'713 to 8'506, p=0.60]. Average costs per day decreased by CHF -3'224 [95% CI -3'811 to -2'631, p<0.001] for PC patients with significant reduction of costs for diagnostic intervention and medication. Higher cost components for PC patients were catering, room, nursing, social counselling and non-medical therapists. In sensitivity analyses, when we restricted PC exposure to 3 days from admission, total costs and average costs per day were significantly lower for PC. CONCLUSION Studies measuring the impact of PC on hospital costs should analyze various cost components beyond total costs in order to understand wanted and potentially unwanted cost-reducing effects. An international definition of a set of cost components, specific for cost-impact PC studies, may help avoid superficial and potentially dangerous cost discussions

Number of hospital beds : population estimate, installed capacity and performed in two mesoregions of Rio de Janeiro, Brazil, 2015

Introduction: Planning health resources in a continental country like Brazil demands adapting the structures to different regions and their needs. Objective: To compare the installed hospital structure (number of existing beds) with the health care parameters proposed by the Brazilian national health system (estimated beds) and the beds per activity performed in two mesoregions of the state of Rio de Janeiro in 2015. Methods: Cross-sectional analysis with data obtained from the information systems of the Brazilian national health system. Results: An excess of hospital beds was identified (208.9% of the ideal average, per activity performed), low occupancy rates (24.2% below the ideal average) and irregular distribution between the mesoregions. Conclusions: The unequal division of resources unrelated to population demands results in higher health care costs and undermines the universality of access and integrality of the care

Degradation potentials of dissolved organic carbon (DOC) from thawed permafrost peat

Global warming can substantially affect the export of dissolved organic carbon (DOC) from peat-permafrost to aquatic systems. The direct degradability of such peat-derived DOC, however, is poorly constrained because previous permafrost thaw studies have mainly addressed mineral soil catchments or DOC pools that have already been processed in surface waters. We incubated peat cores from a palsa mire to compare an active layer and an experimentally thawed permafrost layer with regard to DOC composition and degradation potentials of pore water DOC. Our results show that DOC from the thawed permafrost layer had high initial degradation potentials compared with DOC from the active layer. In fact, the DOC that showed the highest bio- and photo-degradability, respectively, originated in the thawed permafrost layer. Our study sheds new light on the DOC composition of peat-permafrost directly upon thaw and suggests that past estimates of carbon-dioxide emissions from thawed peat permafrost may be biased as they have overlooked the initial mineralization potential of the exported DOC

A review of the importance of mineral nitrogen cycling in the plant-soil-microbe system of permafrost-affected soils—changing the paradigm

The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in favor of organic N compounds is based on the observation that net N mineralization rates in these cold climates are negligible. However, we find here that this perception is wrong. By synthesizing published data on N cycling in the plant-soil-microbe system of permafrost ecosystems we show that gross ammonification and nitrification rates in active layers were of similar magnitude and showed a similar dependence on soil organic carbon (C) and total N concentrations as observed in temperate and tropical systems. Moreover, high protein depolymerization rates and only marginal effects of C:N stoichiometry on gross N turnover provided little evidence for N limitation. Instead, the rather short period when soils are not frozen is the single main factor limiting N turnover. High gross rates of mineral N cycling are thus facilitated by released protection of organic matter in active layers with nitrification gaining particular importance in N-rich soils, such as organic soils without vegetation. Our finding that permafrost-affected soils show vigorous N cycling activity is confirmed by the rich functional microbial community which can be found both in active and permafrost layers. The high rates of N cycling and soil N availability are supported by biological N fixation, while atmospheric N deposition in the Arctic still is marginal except for fire-affected areas. In line with high soil mineral N production, recent plant physiological research indicates a higher importance of mineral plant N nutrition than previously thought. Our synthesis shows that mineral N production and turnover rates in active layers of permafrost-affected soils do not generally differ from those observed in temperate or tropical soils. We therefore suggest to adjust the permafrost N cycle paradigm, assigning a generally important role to mineral N cycling. This new paradigm suggests larger permafrost N climate feedbacks than assumed previously

Permafrost Landscape History Shapes Fluvial Chemistry, Ecosystem Carbon Balance, and Potential Trajectories of Future Change

Intensifying permafrost thaw alters carbon cycling by mobilizing large amounts of terrestrial substrate into aquatic ecosystems. Yet, few studies have measured aquatic carbon fluxes and constrained drivers of ecosystem carbon balance across heterogeneous Arctic landscapes. Here, we characterized hydrochemical and landscape controls on fluvial carbon cycling, quantified fluvial carbon fluxes, and estimated fluvial contributions to ecosystem carbon balance across 33 watersheds in four ecoregions in the continuous permafrost zone of the western Canadian Arctic: unglaciated uplands, ice-rich moraine, and organic-rich lowlands and till plains. Major ions, stable isotopes, and carbon speciation and fluxes revealed patterns in carbon cycling across ecoregions defined by terrain relief and accumulation of organics. In previously unglaciated mountainous watersheds, bicarbonate dominated carbon export (70% of total) due to chemical weathering of bedrock. In lowland watersheds, where soil organic carbon stores were largest, lateral transport of dissolved organic carbon (50%) and efflux of biotic CO2 (25%) dominated. In watersheds affected by thaw-induced mass wasting, erosion of ice-rich tills enhanced chemical weathering and increased particulate carbon fluxes by two orders of magnitude. From an ecosystem carbon balance perspective, fluvial carbon export in watersheds not affected by thaw-induced wasting was, on average, equivalent to 6%–16% of estimated net ecosystem exchange (NEE). In watersheds affected by thaw-induced wasting, fluvial carbon export approached 60% of NEE. Because future intensification of thermokarst activity will amplify fluvial carbon export, determining the fate of carbon across diverse northern landscapes is a priority for constraining trajectories of permafrost region ecosystem carbon balance

A globally relevant stock of soil nitrogen in the Yedoma permafrost domain

Nitrogen regulates multiple aspects of the permafrost climate feedback, including plant growth, organic matter decomposition, and the production of the potent greenhouse gas nitrous oxide. Despite its importance, current estimates of permafrost nitrogen are highly uncertain. Here, we compiled a dataset of >2000 samples to quantify nitrogen stocks in the Yedoma domain, a region with organic-rich permafrost that contains ~25% of all permafrost carbon. We estimate that the Yedoma domain contains 41.2 gigatons of nitrogen down to ~20 metre for the deepest unit, which increases the previous estimate for the entire permafrost zone by ~46%. Approximately 90% of this nitrogen (37 gigatons) is stored in permafrost and therefore currently immobile and frozen. Here, we show that of this amount, ¾ is stored >3 metre depth, but if partially mobilised by thaw, this large nitrogen pool could have continental-scale consequences for soil and aquatic biogeochemistry and global-scale consequences for the permafrost feedback

Arctic soil methane sink increases with drier conditions and higher ecosystem respiration

Arctic wetlands are known methane (CH4) emitters but recent studies suggest that the Arctic CH4 sink strength may be underestimated. Here we explore the capacity of well-drained Arctic soils to consume atmospheric CH4 using >40,000 hourly flux observations and spatially distributed flux measurements from 4 sites and 14 surface types. While consumption of atmospheric CH4 occurred at all sites at rates of 0.092 ± 0.011 mgCH4 m−2 h−1 (mean ± s.e.), CH4 uptake displayed distinct diel and seasonal patterns reflecting ecosystem respiration. Combining in situ flux data with laboratory investigations and a machine learning approach, we find biotic drivers to be highly important. Soil moisture outweighed temperature as an abiotic control and higher CH4 uptake was linked to increased availability of labile carbon. Our findings imply that soil drying and enhanced nutrient supply will promote CH4 uptake by Arctic soils, providing a negative feedback to global climate change
