The palaeobiota from a middle to late Holocene succession in Tom Thumbs Lagoon, N.S.W., Australia, reflects a range of environmental conditions caused by sea-level changes and active estuarine sedimentation. At the base of the succession (~ ?0.4 m AHD) a thin bed, containing molluscs dated at 6.7 ka B.P. by radiocarbon and amino acid racemisation, and foraminifers is indicative of open estuarine conditions. From +0.35 m AHD towards the top of the sequence the charophyte Lamprothamnium succinctum occurs in subrecent deposits. This species is characterised here by statistical measurements, and new characters are described and illustrated. The charophytes record a drop in sea level and the establishment of a lower salinity artificial wetland. The investigation has also established that decalcification in charophytes can be related to acidification produced by the release of organic acids, aggravated after 1928 by anthropogenic pollution.  相似文献

Abstract

This article addresses the puzzle of why Ireland has proved so open to immigration. It compares responses to immigrants in the Republic of Ireland during the Celtic Tiger era and during the post-2008 economic crisis and finds no evidence of a political backlash during the latter period even though opinion polls suggest that opposition to immigration had increased and other evidence suggested that there had been an increase in racist incidents within Irish society. Nor did the resumption of large-scale emigration trigger political hostility to immigrants. The outcome of the 2004 Referendum on Citizenship, which removed a constitutional right to Irish citizenship to the Irish-born children of immigrants, suggested that that nationalism still matters hugely and a latent tendency towards ethnic chauvinism amongst the host population. Yet, a decade after the 2004 Referendum it looked as if the old mono-ethnic sense conception of the Irish nation had been disrupted, at least a little bit.  相似文献

Many scholars contend that Congress rarely matters in the realm of foreign policy. The source of this collective impotence is often explained by the weaknesses in congressional institutions vis-a-vis the president, as well as a general inability to respond effectively to a dynamic international political environment. We contend that the debate over congressional activism has not adequately addressed the role of agenda change. We analyze all roll call votes in the House of Representatives relating to the international affairs agenda between 1953 and 1998. We find that presidents have become significantly more likely to stake out positions on economic and trade issues as compared to other international issues. We also observe that presidential positions in the realm of foreign policy are increasingly characterized by interparty and interinstitutional conflict. While this increased conflict has dramatically decreased the president's ability to successfully pass executive priorities in foreign affairs more generally, presidential success on economic and trade issues has witnessed a significantly greater decline. We infer from these results that changes to the foreign policy issue agenda represent one important factor that has affected not only the incentives for political parties to participate actively, but also the willingness of Congress to challenge the president in the foreign policy debate.Asked one day whether it was true that the navy yard in his district was too small to accommodate the latest battleships.

A preliminary analysis of chert sources and distribution patterns in west Finnmark is described. Three small quarries and a fourth possible source area are situated on the coast west of Alta. Petrographic and geochemical analyses lend tentative support to the proposition that chert from these coastal sources was distributed inland during the Late Stone Age and Early Metal Periods.  相似文献

Policy Bubbles     
We develop the concept of a policy bubble to capture the notion of long‐term overinvestment in a policy. In sketching the relation of policy bubbles to economic bubbles, we describe how these two concepts have similar origins but different trajectories because they are filtered by different institutions. We examine in some detail three likely instances of ongoing policy bubbles: crime policy, school reform (charter schools and private education vouchers), and the contracting and privatization of public services. We show how these cases differ from the housing bubble of 1997–2007, how they differ from each other, and the extent to which they can be considered policy bubbles. Last, we suggest this concept can help unify the policy process literature with the practice of policy evaluation and outline testable hypotheses for future research.  相似文献
