Methane flux: Water table relations in northern wetlands

Abstract: Water table position, through the creation of aerobic and anaerobic conditions in the soil profile, plays an important role in controlling CH 4nflux from wetlands. A laboratory study of peat columns revealed that CH 4emission rates initially increased and then decreased as the water table was lowered from the peat surface to a depth of 50 cm, with the release of CH 4ntrapped in pores. There was a strong hysteresis between CH 4nflux on the falling and rising water table limbs (falling g rising). When expressed as seasonal average values, there was a strong relationship (rs 0.08 n 0.74) between log CH 4nflux and water table position for sites within 5 wetland regions in boreal‐subarctic Canada. The regression coefficients were similar among regions (0.022 n 0.037), but there were differences in the regression constants (0.47 n 1.89). CH 4nflux from drained, forested peatland soils decreased as the water table depth increased, and several sites were transformed from sources to sinks of CH 4. Global CH 4nemissions to the atmosphere may have been reduced by a 1 Tg yr m1nby peatland drainage during the last 100 yr.

Forward-backward asymmetry in top quark-antiquark production

Abstract: We present a measurement of forward-backward asymmetry in top quark-antiquark production in proton-antiproton collisions in the final state containing a lepton and at least four jets. Using a dataset corresponding to an integrated luminosity of $5.4\,\mathrm {fb}^{-1}$, collected by the \DZ\ experiment at the Fermilab Tevatron Collider, we measure the \ttbar\ forward-backward asymmetry to be $(9.2 \pm 3.7)$% at the reconstruction level. When corrected for detector acceptance and resolution, the asymmetry is found to be $(19.6 \pm 6.5)$%. We also measure a corrected asymmetry based on the lepton from a top quark decay, found to be $(15.2 \pm 4.0)$%. The results are compared to predictions based on the next-to-leading-order QCD generator {\sc mc@nlo}. The sensitivity of the measured and predicted asymmetries to the modeling of gluon radiation is discussed.

“Common–Sense” Neoliberalism: Progressive Conservative Urbanism in Toronto, Canada

Abstract: This paper argues that urban neoliberalism can best be understood as a contradictory re–regulation of urban everyday life. Based on an analysis of neoliberalism as a new political economy and as a new set of technologies of power, the paper argues that the urban everyday is the site and product of the neoliberal transformation. Governments and corporations play a key role in redefining the conditions of everyday life through neoliberal policies and business practices. Part of this reorientation of everydayness, however, involves new forms of resistance and opposition, which include the kernel of a possible alternative urbanism. The epochal shift from a Keynesian–Fordist–welfarist to a post–Fordist–workfarist society is reflected in a marked restructuring of everyday life. The shift changes the socioeconomic conditions in cities. It also includes a reorientation of identities, social conflicts, and ideologies towards a more explicitly culturalist differentiation. Social difference does not disappear, but actually becomes more pronounced; however, it gets articulated in or obscured by cultural terms of reference. The paper looks specifically at Toronto, Ontario, as a case study. An analysis of the explicitly neoliberal politics of the province’s Progressive Conservative (Tory) government under Mike Harris, first elected in 1995, demonstrates the pervasive re–regulation of everyday life affecting a wide variety of people in Toronto and elsewhere. Much of this process is directly attributable to provincial policies, a consequence of Canada’s constitutional system, which does not give municipalities autonomy but makes them “creatures of provinces.” However, the paper also argues that Toronto’s elites have aided and abetted the provincial “Common–Sense” Revolution through neoliberal policies and actions on their own. The paper concludes by outlining the emergence of new instances of resistance to the politics of hegemony and catastrophe of urban neoliberalism.

Transnational Business Governance Interactions: Conceptualization and Framework for Analysis

Abstract: This special issue demonstrates the importance of interactions in transnational business governance. The number of schemes applying non-state authority to govern business conduct across borders has vastly expanded in numerous issue areas. As these initiatives proliferate, they increasingly interact with one another and with state-based regimes. The key challenge is to understand the implications of these interactions for regulatory capacity and performance, and ultimately for social and environmental impact. In this introduction, we propose an analytical framework for the study of transnational business governance interactions. The framework disaggregates the regulatory process to identify potential points of interaction, and suggests analytical questions that probe the key features of interactions at each point.
