    While friendship scholarship in the humanities and social sciences has risen exponentially inthe last decade, it focuses almost exclusively on the alliances of great powers. This articleintroduces a new research agenda by drawing upon scholarship that suggests middle powersbehave differently, arguing that middle powers pursue international friendship different thangreat powers. This example is illustrated by comparing how the Netherlands and Denmark,both considered traditional examples of middle powers and of atlanticist states, supported the US during the War on Terror, and how this affected their relationship with the U

    Activity of comets: Gas Transport in the Near-Surface Porous Layers of a Cometary Nucleus

    The gas transport through non-volatile random porous media is investigated numerically. We extend our previous research of the transport of molecules inside the uppermost layer of a cometary surface (Skorov and Rickmann, 1995; Skorov et al. 2001). We assess the validity of the simplified capillary model and its assumptions to simulate the gas flux trough the porous dust mantle as it has been applied in cometary physics. A new microphysical computational model for molecular transport in random porous media formed by packed spheres is presented. The main transport characteristics such as the mean free path distribution and the permeability are calculated for a wide range of model parameters and compared with those obtained by more idealized models. The focus in this comparison is on limitations inherent in the capillary model. Finally a practical way is suggested to adjust the algebraic Clausing formula taking into consideration the nonlinear dependence of permeability on layer porosity. The retrieved dependence allows us to accurately calculate the permeability of layers whose thickness and porosity vary in the range of values expected for the near-surface regions of a cometary nucleus.Comment: 25 pages, 9 figure

    Power between Habitus and Reflexivity – Introducing Margaret Archer to the Power Debate

    This article introduces Margaret Archer’s research on reflexivity to the power debate, alongside Pierre Bourdieu’s already influential concept of habitus. Both offer significant insights on social conditioning in late modernity. However, their tendency to the extreme of social determinism and voluntarism must be avoided. To do so, this article adopts Haugaard’s family resemblance concept of power, describing habitus and reflexivity as an important new binary of power instead of a conceptual zero-sum game. This strengthens the explanatory role of agency, central to the three dimensions of power, without losing sight of constitutive, structural power. It also helps overcome the habitus-reflexivity dichotomy in social theory and provides a starting point to evaluate Archer’s work from a power perspective
