    with S. Amsbury, N. Elhaddad, A. Baillie, M. Lundgren, Y. Verhertbruggen, H. V. Scheller, J. P. Knox, A. J. Fleming, and J. E. Gray
    © 2016 The AuthorsStomatal opening and closure depends on changes in turgor pressure acting within guard cells to alter cell shape [1]. The extent of these shape changes is limited by the mechanical properties of the cells, which will be largely dependent on the structure of the cell walls. Although it has long been observed that guard cells are anisotropic due to differential thickening and the orientation of cellulose microfibrils [2], our understanding of the composition of the cell wall that…Read more

    This paper examines the role of practical reason in connecting moral principles and historical traditions. It looks first at Habermas’ attempt to construct a model of communicative reason that can bridge the gap between the justification of moral principles and their application in practice. The paper then turns to an older debate between Burke and Kant on the relation between theory and practice in the French Revolution. It argues that Burke's account of practical reason as dependent on the cul…Read more
