99Tc levels were measured in seawater samples collected between 2000 and 2002 in the West Spitsbergen Current (WSC) and along the western coast of Svalbard or Spitzbergen and compared with available oceanographic 3-D modelling results for the late 1990s. Additional data from related regions are also presented in order to support the data interpretation. The seawater in the Arctic fjord Kongsfjorden on the western coast of Svalbard is influenced by the WSC, as shown by the 99Tc levels in surface water. By means of the WSC, 99Tc reaches the Eastern Fram Strait, where one branch of the WSC turns west into the East Greenland Current (EGC), and another branch continues northwards into the Arctic Ocean. Surface seawater collected in the central part of the WSC during a cruise on board the R/V "Polarstern" in the summer of 2000, showed higher levels of 99Tc than samples measured in Kongsfjorden in the spring of 2000. However, all levels measured in surface water are of the same order of magnitude. Data from sampling of deeper water in the WSC and EGC provide information pertaining to the lateral distribution of 99Tc. In all vertical profiling surveys (conducted in spring and summer), the highest levels of 99Tc were found in surface water. Comparison with oceanographic 3-D modelling indicates both significant seasonal variations in the lateral stratification of the WSC and variations with depth over shorter vertical distances. This information can be applied in sampling strategies, environmental monitoring, long-range transport of pollutants and physical oceanography.

We use quantitative X-ray diffraction to determine the mineralogy of late Quaternary marine sediments from the West and East Greenland shelves offshore from early Tertiary basalt outcrops. Despite the similar basalt outcrop area (60 000-70 000 km**2), there are significant differences between East and West Greenland sediments in the fraction of minerals (e.g. pyroxene) sourced from the basalt outcrops. We demonstrate the differences in the mineralogy between East and West Greenland marine sediments on three scales: (1) modern day, (2) late Quaternary inputs and (3) detailed down-core variations in 10 cores from the two margins. On the East Greenland Shelf (EGS), late Quaternary samples have an average quartz weight per cent of 6.2 ± 2.3 versus 12.8 ± 3.9 from the West Greenland Shelf (WGS), and 12.02 ± 4.8 versus 1.9 ± 2.3 wt% for pyroxene. K-means clustering indicated only 9% of the samples did not fit a simple EGS vs. WGS dichotomy. Sediments from the EGS and WGS are also isotopically distinct, with the EGS having higher eNd (-18 to 4) than those from the WGS (eNd = -25 to -35). We attribute the striking dichotomy in sediment composition to fundamentally different long-term Quaternary styles of glaciation on the two basalt outcrops.

This article examines the apparent contradictions in Singaporean interpretation and application of its Westminster modeled Constitution in which the Constitution is treated as any other piece of legislation and Western style individual rights are easily overrun. It also examines the Government's particularist claim to Asian values as an explanation for its handling of the Constitution and seeks an alternative approach to understand the Constitution with reference to the Government publication, the Shared Values. The author suggests that this Document serves as a quasi-Constitution, and finds that interpreting two leading cases with this hermeneutic leads to a more satisfactory understanding of the court's decisions. The article concludes that the Government's approach toward the law to create the society it envisioned and published in the Document is a different and pragmatic issue, rather than a result of any fundamental East versus West cultural difference.

Why do some organizations decline while other do not? to study this issue , we introduce technological change into a theory of agency proposed by Laffont and Tirole. We show that the optimal organizational form for production depends on the estent of scale ecoomies and on the cost of monitoring workers. When the discrepancy between ideal and actual forms becomes too great, an organization's viability is threatened. We test this structuralist hypothesis for East and west Gemany over the 1949-1989 period. east Germany's relative decline is explained by an institutional structure the proved incompatible with technological change favoring smaller, flatter organizations.
