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.

Rapid growth in Hispanic population in southwestern Detroit during the 1990s led to a transformation of the area from predominantly non-Hispanic white to Hispanic. Focusing on the Hispanic population, a typology of racial/ethnic changes between 1990 and 2000 is undertaken in 99 census tracts in southwestern Detroit and surrounding suburbs. Two of the tract types that experienced the greatest transition to Hispanic underwent substantial declines in non-Hispanic white population, but still experienced growth in total population. At the same time, these tracts experienced a decline in housing stock, which undoubtedly put pressure on the ability to secure housing. Although Hispanics could afford to reside in predominantly black tracts, few did so, probably indicating competition for scarce housing resources. Contiguous to the rapidly transitioning tracts is the suburb of Dearborn, which contains an established Arab enclave. Median housing values in these tracts were about three times that of tracts in the area undergoing succession to Hispanic population, which helps to explain why these tracts experienced little growth in Hispanic population. Not surprisingly, predominantly white tracts in the suburbs also experienced little growth in Hispanic population due to higher housing values. It is concluded that limited financial resources of Hispanics as well as competition for affordable housing in the city were responsible for the rapid growth and concentration of the Hispanic population in southwestern Detroit. 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

Archaeomagnetic Dating of Pyrotechnological Contexts: a Case Study for Copper Smelting Sites in the Central Timna Valley,Israel 下载免费PDF全文
This study is focused on establishing age constraints for several copper slag deposits at the centre of the Timna Valley (Israel) via reconstruction of their ancient geomagnetic intensities as recorded by the individual slag samples at the time of their formation. The results show a correlation between the location of the slag deposits (labelled as individual ‘mounds’ in our survey) and their inferred ages, reflecting varying socio‐economic and political dynamics in the region. While the slag mounds found at the unprotected foothills represent a variety of dates (mostly Early Islamic), the slag mounds on the hilltops are chronologically constrained to the early Iron Age (late 11th to 10th centuries bce ), supporting the idea for a need for protection during this period. Furthermore, in comparing the new data with previous archaeomagnetic studies from Timna, we can assert the existence of simultaneous copper production at the archaeological Sites 30, 30a and 34. This gives further support to the claim of intense smelting in the central Timna Valley during the early Iron Age. Finally, this project demonstrates the potential of archaeomagnetic experiments to provide chronological insights, and their particular advantage in addressing pyrotechnology‐related cases. 相似文献

The present paper analyses humorous stories circulating among Ethiopian immigrants now living in Israel. Typically told at community gatherings, these narratives articulate the drama of dislocation and the traumatic encounter with life in Israel, by focusing on the embarrassing clash of the quintessential “traditional” Ethiopian, with a new land-scape, time-scape, and body-scape. Characterised by an easy spirit, the revelation of innocence met with forgiving and accepting laughter, these stories enable internalisation and mediation of common ambivalences and vulnerabilities, converting them into elements of pleasure. 相似文献
