The effect of a concurrent auditory task on visual search was investigated using an image-flicker technique. Participants were undergraduate university students with normal or corrected-to-normal vision who searched for changes in images of driving scenes that involved either driving-related (e.g., traffic light) or driving-unrelated (e.g., mailbox) scene elements. The results indicated that response times were significantly slower if the search was accompanied by a concurrent auditory task. In addition, slower overall responses to scenes involving driving-unrelated changes suggest that the underlying process affected by the concurrent auditory task is strategic in nature. These results were interpreted in terms of their implications for using a cellular telephone while driving. Actual or potential applications of this research include the development of safer in-vehicle communication devices.

The UNECE Convention on Long-range Transboundary Air Pollution (LRTAP) is currently working on a revision of the Gothenburg protocol. ICP Waters has used the dynamic model MAGIC to evaluate the effects of future deposition scenarios (COB2020 (current legislation), Low*2020, Mid*2020, High*2020, and MFR2020 (maximum technically feasible reduction) on surface waters. These five deposition scenarios are very similar to one another and represent substantial decreases in deposition for the year 2020 relative to the base year 2000. At all sites the modelled results indicate that chemical recovery will continue into the future. At all but the most acid sensitive sites acid neutralising capacity (ANC) will increase to levels above the critical level for biological damage. Additional improvements in water quality can be obtained in the future with emission reductions beyond MFR2020. ; Norwegian Climate and Pollution Agency

Project manager Kari Austnes ; The current status of surface water acidification related to air pollution in Europe and North America has been assessed using country reports, monitoring data, critical loads and exceedance data, acid sensitivity and deposition maps, and data reported under the European Commission's Water Framework Directive (WFD). Acidification is still observed in many countries, but the extent and severity vary. Maps of acid sensitivity and deposition suggest that surface water acidification is present in regions and countries for which no data or reports were delivered for the current assessment. Existing national monitoring varies in the ability to assess the spatial extent of acidification and the recovery responses of acidified sites. The monitoring requirements under the European Union's National Emission Ceilings Directive are expected to reverse the recent decline in the number of monitoring sites observed in some countries. The information reported under the WFD is currently of limited value in assessing the extent of acidification of surface waters in Europe. Chemical recovery in response to reductions in acid deposition can be slow, and biological recovery can lag severely behind. Despite large and effective efforts across Europe and North America to reduce surface water acidification, air pollution still constitutes a threat to freshwater ecosystems. ; Norwegian Environment Agency (Miljødirektoratet) United Nations Economic Commission for Europe (UNECE) ; publishedVersion

This edited volume brings together leading researchers from the United States, the United Kingdom and Europe to look at the processes leading to segregation and its implications. With a methodological focus, the book explores new methods and data sources that can offer fresh perspectives on segregation in different contexts. It considers how the spatial patterning of segregation might be best understood and measured, outlines some of the mechanisms that drive it, and discusses its possible social outcomes. Ultimately, it demonstrates that measurements and concepts of segregation must keep pace with a changing world. This volume will be essential reading for academics and practitioners in human geography, sociology, planning and public policy
