Democracy, emancipation and widening participation in the UK: changing the âdistribution of the sensibleâ
The broad concern of this paper is how the relationship between education, democracy and emancipation might be conceived. This theme is explored through examining the contribution of a Rancierian conception of emancipation and democracy to rethinking widening participation in higher education. Following Ranciere, it is argued that taking equality as a starting point in higher education, rather than as a goal to be achieved through education, disrupts a prevailing logic of education as necessarily providing a pathway to emancipation. From this view the pedagogic practices of explication and mastery, which Ranciere argues work to separate academic reason and practical reason, need no longer be understood as the only way to be academic. It is proposed that this âredistribution of the sensibleâ enables higher education to be conceived in ways other than available in ongoing educational debates and enables a move beyond an assimilation/recognition binary. Instead, widening participation can be understood as a space for opening up to experience, transformation and change for both academics and students. From this view, democracy is enacted in the here and now, rather than a goal for the future, and practice can be understood as a site for change

Sedimentology and geochemistry of extensive very coarse deepwater submarine fan sediments in the Middle Jurassic of Oman, emplaced by giant tsunami triggered by submarine mass flows
Unusual fining upwards coarse conglomerates overlain by sandstones, thin cherts and green shales occur at the top of the deep-water submarine fan deposits of the Oolitic Limestone Member of the Jurassic Guwayza Formation of Oman. They separate the dominantly submarine fan deposits of the Guwayza Formation from the pelagic shales, fine-grained limestones and cherts of the overlying Sidr Formation. The cross-bedded and graded framework conglomerates occur in extensive, tabular units and are dominated by earlier Mesozoic carbonate clasts with sandy oolitic and peloidal grains derived from fault escarpments and shelf sediments far to the southwest. Subordinate inverse grading, very thick beds, very large floating clasts (up to 100 m long in places) indicate deposition from catastrophic debris flows. Though most palaeocurrents indicate flow from off the platform to the southwest, hummocky cross-bedding shows divergent palaeocurrents suggesting movement in part by deep-water waves. The beds are too coarse for antidune formation and the conglomerate to sand hummocks indicate decelerating flow. There are no nearby large objects to deflect turbidity currents to form divergent flows. We consider that the hummocky cross-stratification, like that in shallow water, was formed by interfering waves. That such coarse, tabular conglomerates affected by wave action occur over extensive areas across deep submarine fan environments, suggests deposition by high-velocity seaward-moving debris and grain flows followed by reworking by waves large enough to redistribute coarse sediment in deep water. The only waves large enough are those of giant tsunami. Petrology and geochemistry show no impact or explosive volcanic constituents in the finer units and the waves involved are too large for generation directly by submarine fault displacements. We suggest that the top Guwayza conglomerates were deposited by very large submarine slides which were then reworked by the tsunami generated by them. Such contemporary massive slope failure deposits are present on the adjacent slope and shelf margin

Internal structure of aeolian dunes in Abu Dhabi determined using ground penetrating radar
A groundâpenetrating radar survey of aeolian dunes in the Al Liwa area of Abu Dhabi reveals a variety of dipping reflectors which are interpreted as primary sedimentary structures. The interpretation of the radar profiles has been confirmed by bulldozing trenches through the study area and comparing logged sections in the trenches with the radar profiles. NNWâ SSEâorientated radar profiles, approximately parallel to the prevailing wind direction, show two sets of dipping reflectors which are interpreted as sets of crossâstratification and secondâ and thirdâorder bounding surfaces. Radar profiles orientated WSWâENE across the prevailing wind direction are dominated by concaveâup reflectors which are interpreted as troughâshaped scours and sets of trough crossâstratification produced by oblique progradation of barchanoid dunes. Nested troughs, with small sets of trough crossâstratification within larger troughs, may be due to reactivation following wind reversal, or the superposition of small dunes on larger dunes and the fill of large dune troughs by smaller dunes. Convexâupwards reflectors are interpreted as linear spurs on the convex portions of sinuous dunes or erosional remnants between troughs. Overall there is a tendency for the larger secondâorder bounding surfaces to dip downwind, which confirms Brookfield's ideas of the relative migration paths of dunes and draa
