Against purity : identity, western feminisms and Indian complications

This thesis argues that Western feminist theoretical models of identity can be productively complicated by the insights of postcolonial feminisms. In particular, it explores ways that Western feminist theory might more adequately sustain a focus on 'women' while keeping open a space for differences such as race and nation. Part One identifies a number of themes that emerge from recent Indian feminist scholarship on the intersections of sex, gender, race, nation and community identities. Part Two uses these insights to look critically at the work of four Western theorists, Rosi Braidotti, Judith Butler, Donna Haraway and Luce Irigaray. I argue that strategies which privilege sexual difference as primary cannot deal adequately with differences such as race and nation. But I also argue that strategies which privilege destabilizing identity can be equally constrained by the logic of dualisms which has made it so difficult for feminists to sustain a focus on women and their differences. Part Three discusses how the insights to be drawn from Indian ferninisms might be taken on board by Western ferninisms in order to develop more complex models of power, identity and the self. Throughout the thesis I draw on a Foucauldian understanding of power as productive, and on Foucault's insight that subjects and identities emerge, not through the imperatives of a single symbolic system, but through the intersection of multiple networks of discourses, material practices and institutions. I argue that, by attending to women's complex location within intersecting landscapes of gender, nation, race and other community identities, feminist models of identity can dispense with a logic of dualisms in order to redefine, and not only destabilize 'women' as the subject of/for feminism. This requires working against purity on three levels. First, it requires a model of power that gives up on the search for pure, power-free zones and works instead with the instabilities power produces as it both enables and constrains women. Second, it requires seeing 'women' as a complex, impure category that bleeds across the apparently coherent borders of identity categories such as gender, race and nation, and contesting discursive constructs of 'Woman' as the pure space of origin upon which these apparently discrete categories stand. Third, it requires the development of alternative models of the self that take these complex, impure spaces as a valid and valorised position from which to act and to speak

Academic Reflection – Narratives of Justice and the Welfare State in Times of Austerity

Considers the continuing relevance of chapter 2 of Nicola Lacey's Unspeakable Subjects (1998), on 'Theories of Justice and the Welfare State', to welfare reform within the contemporary neo-liberal state in Britain. Concludes that Lacey’s concern in that chapter, to open ideas of social justice to a recognition of collective differences and to challenge the public/private divide that stabilises and reinforces normative gender, is ever-more urgent in a political moment that refuses precisely these recognitions

Critical practice of grant application and administration: an intervention

Introduction: Researchers experience increasing pressures to connect with bodies that finance their projects. In this climate, critical scholars face many obstacles as they seek to navigate the treacherous waters of securing external funds. To debate these challenges, the ACME Editorial Collective organized a panel for the 2009 Annual Meeting of the Association of American Geographers in Las Vegas. This intervention represents a follow-up discussion and collective writing process among some of the panelists and members of the audience who attended the panel. Below, we examine the neoliberalization of the current funding systems, discuss the implications for research practice, and make suggestions for critical engagement and transformation. Our suggestions, however, will not be easy to implement, as we can infer from the experience of the radical scholars of the post-1968 generation whose ascension into the upper echelons of North American and European university systems was also associated with the neoliberalization of the funding systems. This intervention represents a modest contribution in the tradition of critical research practice of creating the possibilities for progressive change

Climate-informed stochastic hydrological modeling: Incorporating decadal-scale variability using paleo data

A hierarchical framework for incorporating modes of climate variability into stochastic simulations of hydrological data is developed, termed the climate-informed multi-time scale stochastic (CIMSS) framework. A case study on two catchments in eastern Australia illustrates this framework. To develop an identifiable model characterizing long-term variability for the first level of the hierarchy, paleoclimate proxies, and instrumental indices describing the Interdecadal Pacific Oscillation (IPO) and the Pacific Decadal Oscillation (PDO) are analyzed. A new paleo IPO-PDO time series dating back 440 yr is produced, combining seven IPO-PDO paleo sources using an objective smoothing procedure to fit low-pass filters to individual records. The paleo data analysis indicates that wet/dry IPO-PDO states have a broad range of run lengths, with 90% between 3 and 33 yr and a mean of 15 yr. The Markov chain model, previously used to simulate oscillating wet/dry climate states, is found to underestimate the probability of wet/dry periods >5 yr, and is rejected in favor of a gamma distribution for simulating the run lengths of the wet/dry IPO-PDO states. For the second level of the hierarchy, a seasonal rainfall model is conditioned on the simulated IPO-PDO state. The model is able to replicate observed statistics such as seasonal and multiyear accumulated rainfall distributions and interannual autocorrelations. Mean seasonal rainfall in the IPO-PDO dry states is found to be 15%-28% lower than the wet state at the case study sites. In comparison, an annual lag-one autoregressive model is unable to adequately capture the observed rainfall distribution within separate IPO-PDO states.

Variation of Natural Streamflow since 1470 in the Middle Yellow River, China

Nowadays, as the available water resources throughout the World are becoming depleted, in order to manage and plan water resource better, more and more attention is being paid into the fluctuating characteristics of water discharges. However, the preexisting research was mainly focused on the last half century. In this paper, the natural streamflow observed since 1470 at the Sanmenxia station in the middle Yellow River basin was collected, and the methods of variation coefficient, moving average, Mann-Kendall test and wavelet transform were applied to analyze the dynamic characteristics of the streamflow. The results showed that, (1) between 1470 and 2007, the natural streamflow changed 200–919 × 108 m3, and water discharge varied moderately; (2) in the middle Yellow River basin, it appears that the most severe and most persistent droughts during circa 1868–1990, the periods of 1470s–1490s, 1920s–1930s and 1990s–2000s also presented the condition of sustained low flows; (3) the natural streamflow series shows increasing and decreasing trends during the periods of 1470–1880 and 1881–2007, respectively, but both trends are not significant at >95% confidence; in addition, it is still found the streamflow series shows abrupt changes circa 1845, 1935 and 1960, respectively; (4) within a 250-year scale, there are circa 11, 26, 67 and 120-year periods for natural streamflow at the Sanmenxia station, and the periodicity of the 120-year one is the strongest. The dynamic characteristics of natural streamflow is the comprehensive result by many influencing factors, such as precipitation, temperature, El Niño-Southern Oscillation, sunspots, human activity, etc

Migrant extractability: Centring the voices of egg providers in cross-border reproduction

© 2018 This paper explores reproductive justice from the perspective of those at the beginning of the value chain of reproduction. This vantage point of egg providers can help lend important insights into the wider processes of family-making across borders today. It centres on ethnographic research conducted on contemporary cross-border egg provision performed by female migrant workers in Spain. Through this intersectional perspective, we stand to gain deeper insights into cross-border reproduction more widely. Egg provision can be a way for migrant women to gain temporary financial benefit. In a system that does not provide equal access for migrants to work and care, female migrants make themselves extractable commodities. As such, they are both a commodity and a worker at the same time. The example of female migrant workers providing eggs can be used to reflect more generally on egg provision, and on cross-border reproduction and reproductive justice models as used in queer cross-border family-building. Taken within the broader framework of reproductive justice, and with the struggles of lesbian, gay, bisexual and transgender cross-border reproduction in mind, the paper begins by asking how three intersecting inequalities due to (1) migration/citizenship, (2) joblessness/contract working and (3) race facilitate the industry of cross-border reproduction? In what ways do female migrant workers mobilize their reproductive potential, including time, whiteness, other racial/phenotypic similarity to commissioning parents, and unstable work lives in cross-border egg donation? The paper ends with an argument for focusing analytical and political attention on the needs of those providing eggs; the most prized material resources for cross-border reproduction

The Causes of Foehn Warming in the Lee of Mountains

The foehn effect is well known as the warming, drying, and cloud clearance experienced on the lee side of mountain ranges during “flow over” conditions. Foehn flows were first described more than a century ago when two mechanisms for this warming effect were postulated: an isentropic drawdown mechanism, where potentially warmer air from aloft is brought down adiabatically, and a latent heating and precipitation mechanism, where air cools less on ascent—owing to condensation and latent heat release—than on its dry descent on the lee side. Here, for the first time, the direct quantitative contribution of these and other foehn warming mechanisms is shown. The results suggest a new paradigm is required after it is demonstrated that a third mechanism, mechanical mixing of the foehn flow by turbulence, is significant. In fact, depending on the flow dynamics, any of the three warming mechanisms can dominate. A novel Lagrangian heat budget model, back trajectories, high-resolution numerical model output, and aircraft observations are all employed. The study focuses on a unique natural laboratory—one that allows unambiguous quantification of the leeside warming—namely, the Antarctic Peninsula and Larsen C Ice Shelf. The demonstration that three foehn warming mechanisms are important has ramifications for weather forecasting in mountainous areas and associated hazards such as ice shelf melt and wildfires
