The Jurassic to Cretaceous strata exposed in the Rollrock Section, Sverdrup Basin, Arctic Canada, represent one of the northernmost continuous outcrops spanning this poorly understood transition. The Oxfordian–Valanginian mudstones of the Rollrock Section were deposited in a shallow marine environment and, as such, provide the ideal lithology to investigate the response of high latitude dinoflagellate cyst populations to the frequent environmental perturbations of this time. Using a multivariate statistical approach, distinct palaeoecologically significant groups are identified and directly linked to time and palaeoenvironments, allowing for the reconstruction of underlying long term palaeoenvironmental trends. These palaeoenvironmental trends are identified to be driven by sequence stratigraphic cycles. For the first time, fourth order sequences are recorded from this pivotal period in the Sverdrup Basin and reveal an additional level of short term climatic events that complicate the identification of long term trends. The relationship existing between marine phytoplankton and climate is utilised to decipher the interplay of long-term and short-term climate fluctuations, distinguishing them from evolutionary trends. Two groups of dinoflagellate cysts, identified by process morphology, are recorded to act as environmental proxies. High percentages of proximochorate dinoflagellate cysts, such as Trichodinium erinaceoides, indicate more proximal, high energy, nutrient rich conditions and are dominant in fourth order transgressive systems tracts. High percentages of chorate dinoflagellate cysts, such as Oligosphaeridium complex, signify distal, low energy, nutrient depleted conditions and are dominant in fourth order highstand systems tracts.
Conceptions of negative liberty invariably refer to the removal of objective hindrances to physical action. Conceptions of positive liberty, by contrast, refer to the provision of goods that facilitate forms of empowerment and capacitation. This chapter argues that some of the goods necessary for empowerment and capacitation are subjective, or psychological, most (if not all) of which depends, in one form or another, on what philosophers since Hegel has dubbed "recognition." This chapter has three parts. Drawing from a sample of recognition theorists (Taylor, Honneth, Habermas, and Pippin), Part One defends the salience of recognition for empowerment, capacitation, and agency. Part two then describes forms of psycho-social pathology (damaged agency) that misrecognition of the absence of recognition typically causes. Part three concludes by defending the psychological and ontological validity of recognition as a coherent dimension of social freedom against some frequently raised objections.
This chapter examines how European thinkers working from within and without the Frankfurt School of critical theory have understood the public sphere as a distinctive political category. First-generation members of the school rejected institutional democracy and mass politics as ideologies that mask domination. The succeeding generation, whose most important representative is Jürgen Habermas, rejected that diagnosis. Habermas’s more optimistic assessment of the emancipatory potential of the public sphere as a medium of rational learning sought a middle ground between critics and defenders of liberal democracy. This ambivalence provoked strong counter-reactions from systems theorists, such as Niklas Luhmann, and from adherents of theories of agonal democracy descended from Carl Schmitt, on the right, and Hannah Arendt, on the Left. As we shall see, these reactions are amplified by those who seek to extend the public sphere beyond the boundaries of the nation state.
