Too little,too late: the geochemistry of a 1773 Philadelphia porcelain openwork basket

A dated (1773) openwork basket labelled “PHILADELFIA” attributed to the Bonnin and Morris factory has a lead-bearing, silicious–aluminous–calcic (S-A-C) composition that contrasts with the phosphatic (bone ash) porcelains known to have previously been made during the mid-1760s to early 1770s in what is now the United States. The basket was underfired and so contains relics of a flint (Pb) glass flux, but kiln temperatures were nonetheless sufficient for subsolidus pseudowollastonite and anorthite to have been resorbed, implying that the duration of firing (soaking) near peak kiln temperatures was insufficient to ensure thorough vitrification. During cooling, liquidus pseudowollastonite and silica polymorphs (but not anorthite) formed, showing that the melt was confined to the tridymite–pseudowollastonite cotectic above the Trd–Wol–An eutectic (1170 °C) in the SiO₂–Al₂O₃–CaO system. Rapid cooling is also indicated by quenched silica polymorphs in the relict glass particles. Although Bonnin and Morris employed some former Bow (London, c. 1743–74) workers, the S-A-C wares initially produced by this factory are compositionally distinct from the 1773 basket, which in this regard more closely resembles the body and glaze of a reputed Chelsea triangle-period (London, c. 1745–49) vessel. Regardless of how they obtained this technology, it is ironic that Bonnin and Morris chose to abandon phosphatic pastes in favour of what in Britain had become an obsolete formula.     

The future could be too much fun

Abstract

More than ever before, the twenty-first century is likely to throw into focus the age old question: ‘what am I doing with my life?’ Recent developments in neuroscience mean that a scientific understanding of consciousness is no longer out of the question. The rapidly expanding field of genetic medicine will soon allow single gene disorders such as cystic fibrosis to be treated routinely by gene ‘therapy’ and has already thrown up complex ethical questions surrounding the idea of genetic screening for insurance purposes. And the latest directions in computer science have the potential to challenge our ideas of reality, as well as confusing our understanding of the distinction between information and knowledge. In this paper I revisit the notions of human nature and personal identity in the light of these advances.     

Celebrating 30 years of feminist geographies in the German-speaking countries Germany,Switzerland* and Austria

Abstract

In this paper, we present the development of feminist geographies in the three German-speaking countries Germany, Austria and Switzerland. Since the emergence of feminist approaches in German-speaking geography in the 1980s, feminist geographers situated in these countries have worked closely together within the context of the Working Group “Geography and Gender”. The overview highlights cornerstones of the development of feminist geographies in Germany, Austria and Switzerland such as the Feminist Geography Newsletter (Feministisches GeoRundMail), the Doreen Massey Reading Weekends, the feminist geography student meetings (Feministisches Geograph_innentreffen) and the current DFG-research network “Feminist Geographies of the New Materialism”. By doing so, we try to appreciate both the historical development of feminist geographies and the current situation in Germany, Austria and Switzerland. Highlighting both informal and institutionalized pillars of feminist geographies in these countries, we show how feminist geographies have moved from a marginalized position towards a vibrant field that gains more and more attention within the German-speaking geography community as a whole.     

Quotidian geographies: placing feminism

We discuss Susan Hanson's contributions to geography during the 1970s and 1980s through the lens of quotidian geographies, geographies of the everyday. Beginning from our own experiences as graduate students and new faculty members, we describe the social and theoretical context in which Susan published her initial studies of men's and women's activity patterns that examined gender differences in travel behavior and their origins in men's and women's different household responsibilities. We also review her success peopling the discipline of geography. We conclude that human geography has benefited from the incorporation of feminist theory and methods as Susan predicted.     

Introduction: towards trans geographies

Gender geographies have focused on normatively gendered men and women, neglecting the ways in which gender binaries can be contested and troubled. Trans people question hegemonic conventions that link sexed bodies, gender roles and lives. This collection spans a range of theoretical fields in this context, including trans theories, queer engagement, feminist geographies, gender geographies and sexualities geographies. It offers empirical investigations of trans lives, while addressing the often theoretical use of ‘trans’ to render gender fluid, incoherent and unintelligible. As a whole this themed section questions geography's presumption of man/woman and male/female.     

Trans geographies,embodiment and experience

Queer geographers have long been interested in the interconnections between sexuality and space. With queer theorizing as its hallmark, queer geographical research has made substantial contributions to our understandings of genders, sexualities and embodiment and their constitution in, and production of, space and place. This article examines how trans scholarship intersects with several themes central to queer geographical research – subjectivity/performativity; experience/embodiment; and the historical, political and social constitution of what are now called ‘traditional’ LGBTQ or ‘queer’ urban spaces – and offers geographers interested in intersections between sexuality, gender and the body, alternative and challenging avenues of inquiry. This scholarship highlights, in part, the discontinuities and silences embedded in so-called LGBTQ and queer communities and spaces and points to the need to explore more particularly historical and political conceptualizations of the formations of subjectivities, identities and forms of embodiment in play in these spaces.     

Place, networks, space: theorising the geographies of social movements

This essay examines how geography affects the different types of networks underlying social movements. The principal argument of the paper is that networks forged in particular places and at great distances play distinctive yet complementary functions in broad-based social movements. Not only does the articulation of these different types of networks result in complementary roles, but it also introduces key relational dynamics affecting the stability of the entire social movement. The purpose of the paper is therefore threefold: to provide a conceptual framework for interpreting the complex geographies of contemporary social movement networks, to stress the contributions of place-based relations in social movements and to assess how activist places connect to form 'social movement space'.     

Cyborg geographies: towards hybrid epistemologies

As a mode of critique, the cyborg is often separated from its role as a figuration. This article reviews Donna Haraway's cyborg theory to restate the importance of the cyborg as a figuration in critical methodology. Figuration is about opening knowledge-making practices to interrogation. I argue that the cyborg enables this inquiry through epistemological hybridization. To do so, cyborg figurations not only adopt a language of being or becoming, but narrate this language in the production of knowledges, to know hybridly. The epistemological hybridization of the cyborg includes four strategies: witnessing, situating, diffracting and acquiring. These are modes of knowing in cyborg geographies. To underline the importance of this use of cyborg theory, I review selected geographic literatures in naturecultures and technosciences, to demonstrate how geographers cite the cyborg. My analysis suggests these literatures emphasize an ontological hybridity that leaves underconsidered the epistemological hybridization at work in cyborg figuration. To take up the cyborg in this way is to place at risk our narrations, to re-make these geographies as hybrid, political work.     

Cross over food: re-materializing postcolonial geographies

Recent geographical discussions of postcolonialism have highlighted its emphasis on texts and discourses, its neglect of more material aspects of (post)imperial/colonial domination and the need for detailed empirical research articulating postcolonialism and global capitalism. This paper addresses these issues by reporting on research based in a recent debate in the UK trade press over the 'failure' of Caribbean food to 'cross over' into the UK 'mainstream'. It outlines the contrasting manufacturing and marketing practices of two Jamaican food companies whose accounts of (not) attempting this 'cross-over' illustrate postcolonialism's hybrid, resistant, ambivalent, scale-jumping, boundary-crossing, material cultural politics.     

Currents,visions and voyages: historical geographies of the sea

This paper offers a prospectus for a version of historical geography that puts the seas and oceans at the centre of its concerns. This is pursued in three ways. First, via a discussion of the epistemological and historiographic perspectives that might be taken on geographies of the sea, which argues that the view from the ocean can develop geographies of spaces beyond the local and the national, and can attend to the relationships between the human and natural worlds. Second, through a consideration of the imaginative, aesthetic and sensuous geographies of the sea that contends that maritime worlds open up new experiential dimensions and new forms of representation. Finally, in a survey of the material and social worlds of the oceans that suggests that new life can thereby be breathed into current concerns with global political economy, material geographies, the relationship between knowledge and located practice, and the intersections of social and spatial difference. The paper also provides an introduction to a special issue on the historical geography of the sea.     

Introduction: space,place and the geographies of women's caregiving work

The vast majority of caregivers, whether formal or informal, paid or unpaid, are women. Health care restructuring across the West, inspired by a shift from the welfare to neoliberal state, has greatly impacted caregiving. The idea for this collection arose as a result of a special paper session on the geographies of caregiving, held as part of the Association of American Geographers Meeting (Chicago, 2006). In hearing the papers presented, it became clear that geographers are engaged in interesting and innovative research in this area, much of which involves women's caregiving work in particular. As both unpaid informal family caregiving and paid formal practitioner-provided care are mainly addressed in this collection, they are briefly discussed in this editorial. This is followed by a discussion of the geographical contributions to the growing caregiving literature, which provides the foundation for an overview of ongoing and new research directions. The four articles that make up this special issue are then reviewed in brief. Finally, we identify issues that cut across all four articles, leading to a discussion of future research directions.     

Body Shopping: Reconfiguring geographies of fitness

This article critically interrogates the representational politics implicated in the metaphorical and material production of geographies of embodied fitness. It is intended as a contribution to the growing critical appreciation of the ways in which humans and non-humans are worked together in the production and reproduction of cyborg or hybrid geographies. It therefore mobilises the word fitness in the literal sense of a bodily state, but also in the metaphorical sense of how diverse 'things' come to fit together, how collections of bodies and machines come to be intelligible as inhabitable worlds. But, importantly, this article also argues that this sort of analysis is inadequate if it fails to engage with the ways that the production of human-machinic hybrids is also bound up in the enactment of geographies of ontological purity, a purity that is diffracted, at least in part, through categories such as gender and race. To illustrate this, the paper briefly outlines the ways in which the fitness equipment manufacturer NordicTrack attempts to produce geographies of fitness. Specifically, it suggests that while these geographies muddy the clarity of the boundaries between categories such as male/female, human/non-human, nature/culture, at the same time they work as forces of purification, subtly and not so subtly reinforcing these very same dualisms.
