  • Against this background, we make several advances over the literature. We construct a new dataset that covers virtually the entire global stock market in capitalization terms and find—for this more comprehensive dataset—that industry effects have gone from less than half as important as country effects in the mid-1990s to almost twice as important in recent years. This shift is primarily driven by a dramatic rise in magnitude of industry effects, with country effects roughly stable since the mid-1990s.

  • Land management is presently undergoing enormous change: away from managing single resources to managing ecosystems. From forest to tundra, to desert, to steppe, the world’s ecosystems vary vastly. To manage them effectively we need to understand their geographic distribution better. We need to do this at various levels of detail because ecosystems exist at multiple scales in a hierarchy, from regional to local. Maps are needed to display ecosystem distribution and hierarchy. Until now, information on defining ecosystem boundaries has been scarce.

  • CO2SINK Project – CO2SINK is a European Commission funded mid-scale (60,000 tonnes over two years) demonstration project that aims to increase the knowledge-base of CO2 storage in saline formations and increase public confidence and awareness of GS. The CO2SINK field site is located in Ketzin, Germany, approximately 20 km west of Berlin at the site of a former natural gas storage field. Storage will be at an approximate depth of 650 meters in the saline Stuttgart Formation.

  • absolute pollen frequency (APF) *Pollen data from sediments, expressed in terms of the absolute numbers for each *species, *genus, or *family, per unit volume of sedi- ment and, where deposition rates are known, per unit time. In certain circumstances this approach gives clearer information than does the traditional way of expressing pollen data as *relative pollen frequencies (RPFs). APFs are particularly useful in site comparisons in which one or more high pollen producers vary.
