DEVELOPMENTS IN EQUID HARNESSING AND DRAUGHT IN THE ROMAN EMPIRE AND HAN CHINA: INDEPENDENT OR INTERCONNECTED?

The interconnectedness of the ancient European, Eurasian and Chinese worlds is not doubted, but just what was exchanged and how the transmission of ideas took place is a question very much under investigation. This paper examines peculiarities of equid harnessing and draught across this vast area as a case in point to consider such issues as diffusion and independent invention, especially in relation to the emergence of single draught vehicles.     

Flourishing in fragile academic work spaces and learning environments: feminist geographies of care and mentoring

In this article we discuss the ways in which a feminist ethos of care and the associated practice of mentoring allows feminist geography to flourish in teaching, working and learning spaces. We argue that our working relationship – based on care, mentoring and friendship – is crucial in order to survive and deflect structural inequalities. Our working relationship spans across undergraduate, graduate, postgraduate and early career stages at a single university. We offer our personal stories as examples of establishing and maintaining collaborative mentoring and caring work relationships. Further, our commitment to a feminist ethos of care and mentoring is vital for our selfcare and causes trouble for structural power differentials. First, we share stories about how our working relationship began and developed within the critical, caring and fragile spaces of the Geography Programme at the University of Waikato and other feminist geography networks. Second, literature on care, mentoring and collaboration is discussed, with a focus on feminist politics of mentoring and collaboration. Third, we return to our own experiences to illustrate the ways embodied and emotional subjectivities and associated power dynamics shape mentoring and care relationships. Examples of joint supervision and research are offered to illustrate complex sets of spatially significant emotions, feelings and subjectivities. Finally, we highlight the ways in which place matters if feminist geography is to flourish.     

High-resolution sclerochronological analysis of the bivalve mollusk Saxidomus gigantea from Alaska and British Columbia: techniques for revealing environmental archives and archaeological seasonality

The butter clam, Saxidomus gigantea, is one of the most commonly recovered bivalves from archaeological shell middens on the Pacific Coast of North America. This study presents the results of the sclerochronology of modern specimens of S. gigantea, collected monthly from Pender Island (British Columbia), and additional modern specimens from the Dundas Islands (BC) and Mink and Little Takli Islands (Alaska). The methods presented can be used as a template to interpret local environmental conditions and increase the precision of seasonality estimates in shellfish using sclerochronology and oxygen isotope analysis. This method can also identify, with a high degree of accuracy, the date of shell collection to the nearest fortnightly cycle, the time of day the shell was collected and the approximate tidal elevation (i.e., approx. water depth and distance from the shoreline) from which the shell was collected.Life-history traits of S. gigantea were analyzed to understand the timing of growth line formation, the duration of the growing season, the growth rate, and the reliability of annual increments. We also examine the influence of the tidal regime and freshwater mixing in estuarine locations and how these variables can affect both incremental structures and oxygen isotope values. The results of the sclerochronological analysis show that there is a latitudinal trend in shell growth that needs to be considered when using shells for seasonality studies.Oxygen isotope analysis reveals clear annual cycles with the most positive values corresponding to the annual winter growth lines, and the most negative values corresponding to high temperatures during the summer. Intra-annual increment widths demonstrate clear seasonal oscillations with broadest increments in summer and very narrow increments or no growth during the winter months. This study provides new insights into the biology, geochemistry and seasonal growth of S. gigantea, which are crucial for paleoclimate reconstructions and interpreting seasonality patterns of past human collection.     

De facto,displaced, tacit: The sovereign articulations of the Tibetan Government-in-Exile

Based on ethnographic research on exiled Tibetan political institutions and practices in India, this paper investigates sovereignty in exile. The Tibetan Government-in-Exile (TGiE) remains internationally unrecognised and lacks de jure sovereignty over territory in both Tibet and in exile. However, this exiled administration claims legitimacy as the official representative of the Tibetan population, performs a number of state-like functions in relation to its diasporic ‘citizenry’ and attempts to make its voice heard within the international community. Rejecting arguments that such entities should be viewed merely as discrepant forms of political practice, this paper asserts that the state, sovereignty, and territory can be conceptually disentangled, opening up the theoretical possibility of entities other than territorial states claiming sovereignty. In teasing apart and problematising constituent elements of sovereignty, this paper focuses on three aspects of the TGiE's articulations of sovereignty: its claims to and production of legitimacy, authority and de facto sovereignty; its displaced sovereignty and strategies of territorial governance over non-contiguous spaces in exile; and the mediation of its ambiguous relationship with the host state India through practices of tacit sovereignty.     

Re-naturalizing sugar: Narratives of place,production and consumption

This article analyses the inter-relationships among food consumption practices, marketers' representations of sugar, and the history and political economy of sugar production. It focuses on the 'supermarket narratives'--stories regarding place and production that appear on commodity packaging--used to market sugar in the USA. It explores how competition within the sweetener industry, as shaped by the material qualities of sweeteners, has given rise to supermarket narratives that seek to differentiate sugars on the basis of ideas of place, freshness and environmental sustainability. It also examines how, at the same time, sweetener users have co-operated to maintain and increase consumption in the USA. The article begins with a discussion of historical patterns of sweetener consumption in the USA, and then looks at the genesis of the primary sugar industry lobbying organization. The case study of Florida sugar producers is used to demonstrate the historical antecedents of supermarket narratives and the contemporary geographical specificity of the political economy underlying supermarket narratives.     

URBAN GROWTH EXTERNALITIES AND NEIGHBORHOOD INCENTIVES: ANOTHER CAUSE OF URBAN SPRAWL?*

ABSTRACT This paper suggests a cause of low density urban development or urban sprawl that has not been given much attention in the literature. There have been a number of arguments put forward for market failures that may account for urban sprawl, including incomplete pricing of infrastructure, environmental externalities, and unpriced congestion. The problem analyzed here is that urban growth creates benefits for an entire urban area, but the costs of growth are borne by individual neighborhoods. An externality problem arises because existing residents perceive the costs associated with the new residents locating in their neighborhoods, but not the full benefits of new entrants which accrue to the city as a whole. The result is that existing residents have an incentive to block new residents to their neighborhoods, resulting in cities that are less dense than is optimal, or too spread out. The paper models several different types of urban growth, and examines the optimal and local choice outcomes under each type. In the first model, population growth is endogenous and the physical limits of the city are fixed. The second model examines the case in which population growth in the region is given, but the city boundary is allowed to vary. We show that in both cases the city will tend to be larger and less dense than is optimal. In each, we examine the sensitivity of the model to the number of neighborhoods and to the size of infrastructure and transportation costs. Finally, we examine optimal subsidies and see how they compare to current policies such as impact fees on new development.
