Free Inverse Semigroups

Abstract: Various methods have been given for establishing the existence of the free inverse semigroup FIA on a set A, and for constructing it explicitly (see, for example, [2], [5], [7], [9], [10], [11]). In this paper we outline a graph-theoretic technique for representing the elements of FIA. This depends on the notion, introduced here, of a word-tree on A. With the aid of this technique various properties of FIA are easily deduced: some of these are stated below.

Phosphorus in groundwater – an overlooked contributor to eutrophication?

Abstract: This paper presents the first international assessment of phosphorus concentrations in groundwater, using data from the Republic of Ireland, Northern Ireland, Scotland, England and Wales. Phosphorus is considered to be the main limiting nutrient in most freshwater ecosystems. Controlling phosphorus inputs is thus considered the key to reducing eutrophication and managing ecological quality. Very little attention has been paid to evaluating transfers via groundwater due to the long-held belief that adsorption and metal complex formation retain the majority of potentially mobile phosphorus. In each country, ecologically-important phosphorus thresholds are exceeded in a significant number of groundwater samples. The relative contributions of potential sources for these elevated concentrations are currently unclear but there is evidence to suggest that they are at least partly anthropogenic. The results suggest that groundwater P concentrations are such that they may be a more important contributor to surface water phosphorus than previously thought.

Becoming public: public pedagogy, citizenship and the public sphere

Abstract: This paper explores the question what kind of educational work can be done in attempts to reclaim or reinvigorate the public sphere. Through a discussion of the intersection of public sphere and public space, it engages with the work of Hannah Arendt in order to outline a conception of the public sphere as a space for civic action based on distance and the conservation of a degree strangeness rather than on commonality and common identity. The discussion of the educational work that can be done to support the public quality of common spaces and places focuses on three interpretations of the idea of public pedagogy: that of public pedagogy as a pedagogy for the public, that of public pedagogy as a pedagogy of the public and that of public pedagogy as the enactment of a concern for the public quality of human togetherness. The latter form of public pedagogy neither teaches nor erases the political by bringing it under a regime of learning, but rather opens up the possibility for forms of human togetherness ...
