Dettmann, M.E., Clifford, H.T., Peters, M., June 2012. Emwadea microcarpa gen. et sp. nov.—anatomically preserved araucarian seed cones from the Winton Formation (late Albian), western Queensland, Australia. Alcheringa, 217–237. ISSN 0311-5518. A new genus and species, Emwadea microcarpa Dettmann, Clifford & Peters, is established for ovulate/seed cones with helically arranged cone scales bearing a centrally positioned, inverted ovule from the basal Winton Formation (late Albian), Eromanga Basin, Queensland. The cones are small, prolate ellipsoidal (9.5–14 mm vertical axis, 6.3–8.7 mm transverse axis) with wedge-shaped cone scales bearing winged seeds attached adaxially to the scale only by tissues surrounding the vasculature entering the ovule. Ovuliferous tissue that is free from the cone scale extends distally from the chalaza; the seeds' lateral wings are derived from the integument. Foliage attached to the cones is spirally arranged, imbricate and with spreading and incurved bifacial blades with acute tips; stomata are arranged in longitudinal files and are confined to the adaxial surface. The cone organization testifies to placement within the Araucariaceae, and is morphologically more similar to Wollemia and Agathis than to Araucaria.

‘Organisation and Method’ (O&M) was a discipline promoted in Britain in the first half of the twentieth century as a way of improving the efficiency of administrative enterprises. O&M practitioners were influential actors in the implementation of various information technologies in British businesses. When computers became the new technology, their introduction was seen as a natural adjunct to O&M work. The O&M practitioners understood the connections between the individual tasks to be done, the final outcome desired, and the technologies available. The practice of organizational ‘insiders’ acting as the dedicated mediators of technological introduction resulted in some remarkable successes in computer introduction in Britain in those years. Eventually the O&M approach would be superseded by purely technical experts, arguably to the detriment of user satisfaction. 相似文献

Jonah 1 draws upon the myth of the battle against the sea. Most noticeable is the presence of the triad God, wind, and sea. These elements are present primarily in Genesis 1 & 8, Exodus 14 & 15, Enuma Elish and the Gilgamesh Epic, each retelling the myth of the cosmic battle. Jonah’s allusions, however, go beyond God, wind, and sea and include, for example, the use of Jonah’s name “dove” with reference to the flood accounts. The present essay illustrates these connections, among others, and maintains that the prophet Jonah represents Israel and that the book employs this common myth ironically, to the end that Jonah/Israel is punished rather than delivered through the actions of YHWH. 相似文献

In recent years “volume” has become a key analytic idea, and tool, for re‐imagining and making sense of historical and contemporary socio‐cultural and geopolitical phenomena. This paper argues that this important work could be pushed in new directions by thinking seriously of how volume might otherwise be interpreted spatially, as capacity. Accordingly, in this paper, we address what we call a “politics of capacity”. To do so, we draw specifically on debates in carceral geography and, in particular, the pressures on the prison system to illustrate our argument. Drawing on notions of “operational capacities” and “capacity building” in the prison setting, we outline a manifesto for volumetric thinking that moves beyond expressions of power that cut through height, depth and angles, to an understanding of how power is conveyed through maximum and minimum capacities; density and mass; and capacity‐building techniques. 相似文献
