U-series dating of soda straw stalactites from excavated deposits: method development and application to Blanche Cave, Naracoorte, South Australia

This study aimed to further test the method, reported by St Pierre et al. (2009), to develop robust chronologies of deposits in limestone caves through U/Th (Uranium/Thorium or U-Series) dating of soda straw stalactites. The chronology of fossil bearing deposits at Blanche Cave was further constrained with thermal ionisation mass spectrometry (TIMS) U/Th dating of 17 additional soda straw stalactite samples, and results were compared to recalibrated ¹⁴C ages of charcoal. The results support the assertion that soda straw stalactites can provide ages close to the time of sediment deposition and may be used as reliable chronological markers, particularly for periods reaching or beyond the radiocarbon dating limit. The application of an enhanced cleaning technique facilitated the reduction of detrital Th in samples, significantly increasing age accuracy and precision. Additionally U/Th age accuracy and precision was increased through the application of site-specific measured U/Th ratios to correct for the detrital ²³⁰Th component in samples.     

Unraveling Ravelstein: Saul Bellow's Comic Tragedy

Abstract

This article argues that international relations (IR) theory, defined by its paradigms, theories, and models, has responded not to questions of human experience in world politics, but rather, has been primarily an exercise in self-definitional or privately satisfying research interests. I demonstrate this through analysis of two of the most cited and discussed IR approaches of the past half-century, Waltz's structural realism and Wendt's constructivism. The article argues that a reconstruction of IR premised on John Dewey's pragmatism would enable IR to succeed in responding to questions of practical import. Such questions inherently cannot be determined by privately satisfying research interests of academia, but rather, are defined as problems of lived human experience in world politics as determined by the public itself.     

Ecomuseums and the Democratisation of Japanese Museology

The idea of the ‘integrated museum’, a more socially inclusive form of cultural institution, was a key outcome from the UNESCO/ICOM ‘Round Table of Santiago’ in 1972. Many of the concepts embodied in this idea became part of ecomuseum philosophy and practice during the 1970s and 1980s, in particular the need to involve local communities and make museums more democratic. The ecomuseum has the potential to be a socially inclusive mechanism and is now a worldwide phenomenon. Many of its tenets (the museum as territory, fragmented sites, in situ conservation and community leadership) are used—in a variety of ways and with varying success—as a mechanism to conserve cultural and heritage resources and to construct and promote local or regional cultural identities. Although the philosophy and practice of ecomuseums has been subject to criticism, they are still being created, mainly in rural areas, as a means of conserving traditional landscapes and ways of life. Japan has embraced the ecomuseum philosophy, and three contrasting ecomuseums (Hirano, Asahi and Miura) are described here, their roles analysed and their democratic nature questioned. It appears that the ecomuseum does have the ability to be a truly democratic method of heritage conservation, but that ultimately much depends on leadership and the identification of the local community as the key stakeholder.     

Expanding the utility of Uranium-series dating of speleothems for archaeological and palaeontological applications

Uranium-series (U-series) dating of speleothems is frequently used for palaeoclimate studies but its archaeological and palaeontological applications are limited to stratigraphically significant speleothem formations, such as flowstones, to provide maximum and minimum temporal points. This study targeted soda straw stalactites for U-series dating. In contrast to other speleothem formations, soda straw stalactites are fragile, have typically short life spans (usually only years but rarely up to a few hundred years) and are frequently incorporated into cave deposits. Results of thermal ionisation mass spectrometry (TIMS) U-series dating of soda straw stalactites from palaeontological excavations at Blanche Cave, South Australia, show that small, dense, clean straws tend to yield ages closest to the time of stratigraphic deposition. A correlation between soda straw U-series ages and radiocarbon ages of charcoal from the site is shown. Multiple soda straw age determinations for a single stratigraphic unit are required in order to verify age concordance. In conjunction with other dating methods, U-series dating of soda straw stalactites may help to significantly constrain the age of stratigraphic units and associated archaeological and palaeontological deposits in order to provide more robust chronologies. Here we advocate the collection of soda straw stalactites at future excavations of limestone cave sites.     

Propaganda by the Book: Contextualizing and Reading the Zhejiang GMD’s 1929 Textbook Essentials for Propaganda Workers

The Nationalist Party (GMD) had been writing and issuing documents of many types for some years before Nanjing was established as the capital of the Republic of China in 1927/1928. From its earliest days, doctrines were advanced via cause-oriented newspapers and journals. Even more important, the Soviet-sponsored reorganization of the GMD in the early 1920s had yielded a far-reaching party propaganda operation tied to Sun Yat-sen’s notion of political tutelage. But how was propaganda to work in practice? And at whom was it to be aimed? This article seeks to address aspects of these questions by assessing a textbook for propaganda workers that was issued in the name of the GMD’s Zhejiang Provincial Executive Committee’s Propaganda Department in October 1929, half a year after the GMD’s foundational right-wing Third Party Congress. Although Essentials for Propaganda Workers does not fully operationalize Sun’s version of political tutelage, it can nonetheless be seen to reflect the central party’s efforts to implement tutelage and supervision, not only of the Chinese masses suggested by Sun’s program, but also of party propaganda workers in Zhejiang. In that regard, it reveals the astonishingly rapid ideological realignment of the GMD into an anti-Communist party, not only at the national level, which is well known, but also on the provincial and lower levels. Drawing on material from the GMD Archives in Taipei, this article addresses issues of party organization, control, mobilization, inner party dynamics, and message content in the GMD’s propaganda activities in Zhejiang province in the late 1920s. “Propaganda by the Book” adds to our knowledge of the organizational practices of both the central GMD in Nanjing and the Zhejiang provincial GMD as well as to the social history of Republican China’s official print culture.     

Immigration, the internet, and spaces of politics

This paper examines the kinds of politics that are enabled by the Internet with respect to immigrants to the United States; its primary concern is whether the political spaces created through the Internet can foster incorporation of immigrants in the political community or whether the political activity on the Internet seems likely to lead to a more fractionalized political community in which the position of immigrants remains marginal. This exploration is based first on a random sample of web-sites about immigration and second on a more targeted sample of sites aimed specifically at two immigrant groups. The analysis of web-sites indicates that there is a great deal of information about immigrants on the Internet, and that most of it seems to be directed to service providers, policy makers, and researchers. There is relatively little discussion by or about immigrants, and beyond a few notable sites, there is almost no sign of mobilization. To the extent that the Internet is used to create new political spaces, it may not be spaces for deliberation and discussion. Rather, the political spaces seem to be informational spaces in which the politics are not easily or directly read.

A-Awda, The Palestine Right to return Coalition, is a broad-based, non-partisan, global, democratic association of grassroots activists and organizational representatives. Our objective is to educate the international community to fulfill its legal and moral obligations vis-à-vis the Palestinian people. Al-Awda develops, coordinates, supports and guides, as needed, global and local grassroots initiatives for action related to Palestinian rights.

The Internet is widely heralded as opening spaces for a wide variety of politics and political voices. But as it is praised for its inclusiveness, it is also pilloried for enabling the fragmentation of political opinion without providing a forum in which common political ground can be identified or consensus achieved. In the former view, the Internet fosters greater inclusion in democratic debate and political community. In the latter view, it contributes to a weakening of the bonds that are necessary for a political community to reach consensus and to provide guidance for democratic governance.Consider the examples in the epigraph to the paper. Al-Awda is a political movement devoted to securing the right of return for Palestinian refugees and their families. It organizes marches and demonstrations in cities across the US and Western Europe. One reason for the apparent mismatch between the locations of the “problem” and of the “action” is that many – though by no means all – of the participants in the marches are immigrants from the Middle East or they are of Arab descent. While the organization is based in Massachusetts, most of the mobilization through it occurs on-line, and it is not clear that there is either a permanent staff or regular meetings, other than the marches. Café Arabica provides a venue for discussion of a wide range of topics related to Arab culture and politics. Much like the romanticized café society, discussion can be lively and seems to include a wide range of participants and viewpoints. Café Arabica includes an on-line discussion forum, again with many of the participants apparently either being from the Middle East or the descendants of immigrants from the region. It labels itself as an Arab-American on-line community.These two web-sites were not chosen at random. They both relate to immigrants – social groups that are often not able to participate in political discussion and debate in their host countries. As such, these sites exemplify both the possibilities and the limitations that commentators have identified when they discuss the Internet and its role in fostering political dialogue. Some people would see these sites as signs of a group that wants to use the political process in one country to influence events in another country. Some people will read these sites as a an indication that at least one immigrant group – if not all immigrants – refuse assimilation, which is the basis of incorporation into the American political community. Still others will view these sites as attempts to incorporate a set of political voices and agents into a more inclusive political community. This paper examines the use of the Internet in political debate and mobilization around immigrants in the United States. It considers the nature of political discussion on the Internet and the agents involved in it. The overarching concern is whether the Internet fosters a more inclusive political community or whether it leads to alternative political spaces that remain unincorporated with respect to the political community of the host society.The paper is organized in four sections. The first provides a background for the debates about immigrants, the Internet, and politics. The second section is an overview of the theoretical debates about the public sphere as a political space in which members of a polity can participate and the ways in which the Internet may transform that space. The third section highlights some of the key issues that condition migrants’ acceptance into a polity, focusing primarily on the United States. With these sections serving as background, the final section of the paper explores political discussion on the Internet by and about immigrants. This exploration is based first on a random sample of web-sites about immigration and second on a more targeted sample of sites aimed specifically at two immigrant groups. The goal in these examinations is to evaluate the extent to which the Internet can provide the basis of a political space in which issues related to the incorporation of immigrants can be debated or whether it is a space that fosters a more fractionalized politics unlikely to lead to greater political incorporation of immigrants.
