Underwater excavations at the Classic period (a.d. 300–900) ancient Maya salt works of Chan b’i and Atz’aam Na in Paynes Creek National Park, Belize, reveal activity areas associated with a substantial salt industry for distribution to nearby southern Maya inland sites where this biological requirement was scarce. Wooden architecture and salt making artifacts are abundantly preserved in a peat bog composed of red mangrove. Excavations, screening, and analysis of recovered material at the submerged underwater sites reveal that the artifacts are overwhelmingly briquetage: pottery vessels used to evaporate salty water by heating over fires to make salt. The spatial distribution of briquetage in relation to the interior and exterior of buildings reveals that salt production was occurring indoors. The plethora of briquetage and the scarcity of domestic artifacts indicate that the sites were specialized salt works and not physically attached to households.  相似文献

Recently in their research Goodale et al. (2010) as well as that of Vardi et al. (2010) independently tackled issues of effectively measuring attrition/gloss rates on sickle blade tools from Southwest Asia. Interestingly, while applying new methodology to analyzing sickle tools from different cultural and temporal contexts, these two papers arrived at a similar conclusion: sickle tools were likely very expensive to make, and thus, considerations were made during their production to ensure long use-lives to benefit the people who made and used them in prehistory. Stemp et al. (in this issue) provide a methodological critique of both studies. In addressing their critique we make several points. First it is important to note that Stemp et al. provide no new experimental analysis to justify their assertions, and their critique is ultimately, at best, guesswork. Second, the minimal reanalysis of the data Stemp et al. do conduct arguably lead to the same preliminary conclusion at which we originally arrived: the prehistoric sickle blades we examined were used longer than those we replicated. As stated in our original paper, lithic use-wear studies often do not address issue of reliable and reproducible methods. We believe that our original study helps fill this missing component, and that measuring edge thickness is much less subjective than conventional features on stone tools traditionally identified microscopically. From our perspective, Stemp et al. present largely unsupported critical commentary, lacking substantial reanalysis or experiments to complement or justify their commentary. In the end Stemp et al. provide little more than interesting ideas and conjecture.  相似文献

Abstract

Politics and Passion corrects liberal theory that conceives politics as rational deliberation among autonomous individuals who voluntarily associate in groups to advance their chosen life plans. Freedom and equality for individuals, insofar as they can be approximated, depend, Walzer contends, on passionate political activity and state policy that empower marginalized and diverse groups. Ethical principles and democratic deliberation are insufficient for group politics. Theological ethicists should welcome and learn, once again, from Walzer. However, a liberal conception of justice that avoids naiveté about individual autonomy and democratic deliberation should have a greater role in politics, even the politics of group pluralism and equality, than Walzer apparently permits. Respect for the dignity of individuals requires it.  相似文献

Abstract

The Eora Aboriginal People are the original inhabitants of the Sydney region [in NSW, Australia]. There are an estimated 2, 000 Aboriginal rock engravings in Sydney. Some museums in Sydney now acknowledge the traditional Aboriginal owners and use Eora words to name their exhibitions. These include: Ngaramang bayumi – music & dance (Powerhouse Museum); Merana Eora Nora – first people (Australian National Maritime Museum); Yiribana (Art Gallery of New South Wales); and Cadi Eora Birrung: Under the Sydney Stars (Sydney Observatory). The Aboriginal history of Sydney, however, is only told at the Museum of Sydney with installations, videos and spoken exhibits about Eora, the indigenous peoples of Sydney. This paper reviews the Eora Aboriginal exhibits at the Museum of Sydney. It questions whether visitors to Sydney learn about Bennelong and Pemulwuy, two key Aboriginal figures in the the early European settlement around Sydney Harbour. Sydney Aboriginal Discoveries on their Dreamtime cruise of Sydney Harbour provide another interpretation of Eora history and culture. The paper suggests the Eora heritage of Sydney should be more widely interpreted in Museums, National Parks and other public venues to rightfully acknowledge this Aboriginal history.  相似文献
