The distribution and morphometry of lakes and reservoirs in British Columbia: a provincial inventory

An inventory of provincial lakes and reservoirs has been developed to characterise and assess the distribution and morphometry of standing water bodies in British Columbia. In the province, there are over 241,500 lakes and reservoirs greater than 1,000 m ² in size. These water bodies cover 2.37 percent of the province area and contain an estimated 521 km ³ of water (312 km ³ in natural lakes and 209 km ³ in reservoirs). A hypsometric relation suitable for order-of-magnitude estimates of lake volume from lake area is presented. Based on the distribution and morphometric attributes of lakes, several distinctive limnologic regions were identified, including the northeastern Alberta Plateau (highest proportion of circular lakes), the southwestern Alberta Plateau (lowest lake density/coverage and highest proportion of irregularly shaped lakes) and the Milbanke Strandflat (highest density of lakes). Observed regional and scale-related patterns in lake distribution/morphometry appear to be largely related to geomorphic controls, particularly tectonic and glacial history. Large-scale hydrologic implications of these standing water bodies and potential ecosystem/water resource management applications of the provincial inventory are also discussed.     

Pricing, Capacity Choice, and Financing in Transportation Networks

Abstract.  This paper explores interrelations between pricing, capacity choice, and financing in transportation networks. We build on the Mohring‐Harwitz result on self‐financing of optimally designed and priced roads and investigate it in a network environment under various types of second‐best regulation. A small network model with endogenous car ownership demonstrates that optimal congestion pricing and capacity choice over an entire network may cause user prices to increase more in initially mildly congested areas compared to heavily congested areas. Furthermore, a flat kilometer charge under optimal capacity choice may result in first‐best efficiency gains.     

Technoscience,Neuroscience, and the Subject of Politics

Although narrative models have been employed for quite some time in historiography, in sociology, and in certain psychoanalytic theories, the tendency towards narrativization has also become more dominant in reference to the positive sciences. This article presents two postmodern versions of the narrative dissolution of certain modern scientific-metaphysical concepts in the wake of the establishment of technoscience and neuroscience: Vattimo's Heideggerian account of technoscience as immanent pluralization of worlds, and Dennett's cognitivist account of the emergence of the plural self. Both claim not only that former central agencies like the Cartesian cogito can be dismissed as metaphysical but that narrative pluralization entails an (at least implicit) endorsement of liberal democracy as the only viable political model today. Employing arguments put forth by ?i?ek and Malabou, some of the deficiencies of this affirmative short circuit of technoscience/neuroscience with liberal-democratic politics will be examined.     

Neandertals,early modern humans,and rodeo riders

In 1995 Berger and Trinkaus (J. Archaeol. Sci. 22, 841–852) proposed that the anatomical distribution of Neandertal trauma, with a predominance of upper body lesions, reflected close-quarter ambush hunting as dictated by the available Middle Paleolithic weaponry (the “Rodeo rider” hypothesis). The necessity for mobility among these Late Pleistocene foragers, as a factor possibly reducing the number of preserved lower limb injuries, was considered as an alternative explanation. The accumulating data on Upper Paleolithic injuries and Middle Paleolithic weaponry, considerations of differential skeletal susceptibility of minor trauma, and evidence of interhuman violence, plus the importance of mobility for Late Pleistocene human existence, suggest that hunting injuries may explain only part of the pattern. The purpose of this note is not to resolve to ultimate factors behind the anatomical distribution of traumatic lesions among the Neandertals (or early modern humans). It is 1) to emphasize that there are multiple probable contributing factors other than close-quarter ambush hunting due to the limitations of Middle Paleolithic weaponry, and 2) to open the discussion to alternative interpretations.     

Interrogating post-democratization: Reclaiming egalitarian political spaces

There is now an emerging body of thought on the dynamics of de-politicization, the ‘disappearance of the political’, the erosion of democracy and of the public sphere, and the contested emergence of a post-political or post-democratic socio-spatial configuration. I situate and explore this alleged ‘post-democratization’ in light of recent post-Althusserian political thought. I proceed in four steps. First, I discuss the contested configurations of this post-politicization and the processes of post-democratization. In a second part, I propose a series of theoretical and political arguments that help frame the evacuation of the properly political from the spaces of post-democratic policy negotiation. This diagnostic is related to a particular interpretation of the distinction between ‘the political’ and ‘polic(e)y/‘politics’. In a third part, I argue how emancipatory–democratic politics can be reclaimed around notions of equality, and freedom. In the concluding part, perspectives for re-vitalising the political possibilities of a spatialized emancipatory project are presented. The crux of the argument unfolds the tension between politics, which is always specific, particular, and ‘local’ on the one hand and the universal procedure of the democratic political that operates under the signifiers of equality and freedom on the other.
