Downers: Crip Affect and Radical Relationalities

Taking up prior formulations of crip affect, I explore the positionality of the downer as one whose body complicates global economies of social and political encounter. Engaging with neoliberal formulations of embodiment and the co-constitutive forces of heteronormativity and compulsory able-bodiedness (McRuer, 2006), I look at the ways in which many theoretical and political disability justice projects position disability as complementary to consumer capitalism, producing normative frameworks into which certain abnormal embodiments can be incorporated. I propose that the downer, as a relational body that proliferates social dis-ease and economic dysfunction, mobilizes crip affect ironically and creatively. Through processes of becoming (Deleuze and Guattari 1987; Kim 2015; Puar 2015), downers resist assimilation into biomedical frameworks, and in doing so, propose generative forms of social, economic, political, and corporeal unintelligibility. This article is, itself, an exercise in becoming downer. It renders habitable an ostensibly uninhabitable positionality

Demographic and temporal variations in immunity and condition of polar bears (\u3ci\u3eUrsus maritimus\u3c/i\u3e) from the southern Beaufort Sea

Assessing the health and condition of animals in their natural environment can be problematic. Many physiological metrics, including immunity, are highly influenced by specific context and recent events to which researchers may be unaware. Thus, using a multifaceted physiological approach and a context-specific analysis encompassing multiple time scales can be highly informative. Ecoimmunological tools in particular can provide important indications to the health of animals in the wild.We collected blood and hair samples from free-ranging polar bears (Ursus maritimus) in the southern Beaufort Sea and examined the influence of sex, age, and reproductive status on metrics of immunity, stress, and body condition during 2013–2015.We examined metrics of innate immunity (bactericidal ability and lysis) and stress (hair cortisol, reactive oxygen species, and oxidative barrier), in relation to indices of body condition considered to be short term (urea to creatinine ratio; UC ratio) and long term (storage energy and body mass index). We found the factors of sex, age, and reproductive status of the bear were critical for interpreting different physiological metrics. Additionally, the metrics of body condition were important predictors for stress indicators. Finally,many of these metrics differed between years, illustrating the need to examine populations on a longer time scale. Taken together, this study demonstrates the complex relationship between multiple facets of physiology and how interpretation requires us to examine individuals within a specific context

Resolving diverse oxygen transport pathways across Sr-doped lanthanum ferrite and metal-perovskite heterostructures

Perovskite structured transition metal oxides are important technological materials for catalysis and solid oxide fuel cell applications. Their functionality often depends on oxygen diffusivity and mobility through complex oxide heterostructures, which can be significantly impacted by structural and chemical modifications, such as doping. Further, when utilized within electrochemical cells, interfacial reactions with other components (e.g. Ni- and Cr-based alloy electrodes and interconnects) can influence the perovskite's reactivity and ion transport, leading to complex dependencies that are difficult to control in real-world environments. Here we use isotopic tracers and atom probe tomography to directly visualize oxygen diffusion and transport pathways across perovskite and metal-perovskite heterostructures, i.e. (Ni-Cr coated) Sr-doped lanthanum ferrite (LSFO). Annealing in 18O2(g) results in elemental and isotopic redistributions through oxygen exchange (OE) in the LSFO while Ni-Cr undergoes oxidation via multiple mechanisms and transport pathways. Complementary density functional theory (DFT) calculations at experimental conditions provide rationale for OE reaction mechanisms and reveal a complex interplay of different thermodynamic and kinetic drivers. Our results shed light on the fundamental coupling of defects and oxygen transport in an important class of catalytic materials.Comment: 39 pages, 10 figure

Untangling the “messy” legislative basis of tourism development planning : five cases from Australia

This article reports on a scoping study examining the legislative basis for tourism development and planning in Australia. While planning is vital to facilitate strategic decision-making regarding the appropriate nature and scale of tourism-related developments within a destination, the legislative frameworks that provide for, control and regulate many aspects of tourism development have neither been identified nor collated in an integrated manner. This research used a case-study methodology to examine the range and scope of legislation impacting tourism development in Australia. The study identified 285 current Acts that were categorized into five broad themes. On the basis of these findings, a number of recommendations for identification, collaboration and education regarding the legislative environment have been postulated.Griffith Business School, Department of Tourism, Sport and Hotel ManagementNo Full Tex
