The first known ammonite from the Maastrichtian of the Perth Basin, a single, incomplete specimen of Grossouvrites gemmatus (Huppé, 1854), is described from core material from the Lancelin No. 1 borehole. Foraminiferal and nannoplankton evidence date the ammonite as middle Maastrichtian; its age is also assessed on the basis of dinoflagellate assemblages from this section, but these give a less precise dating. The position of the ammonite with respect to a mid-Maastrichtian disconformity, which probably extended along much of the Western Australian margin is discussed. 相似文献

This paper extends theoretical and empirical debates on knowledge transfer practices in geographically dispersed project teams using a range of communications media. It presents quantitative data comparing work interactions between dispersed and co-located teams in five international, project-based firms. It shows that contrary to conventional wisdom, their respective practices are similar for many work activities such as search and routine information exchange. However dispersed team members validate, verify and consult differently to the respective co-located teams. Qualitative data from interviews and observation then illustrates typical interactions using the differing means and media available to the observed project teams, such as task decomposition and emergency corrective work. Due to an unfortunate oversight one of the references in this article is incomplete. It can be found here. 相似文献

Speaking in particular of Oceanic societies, my intention is to reverse the gestalt of Le totemisme aujourd'hui to foreground the role of difference as a fundamental condition of the possibility of society – difference between as well as within societies. I take the point that difference is not just an historical circumstance but that it is indeed a positive value. Accordingly, differentiation is not so much a natural process as it is a cultural intention. 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.
