Introduction: democracy, citizenship, sovereignty, politics

About the book: Democracy, Citizenship and the Global City focuses on the controversial, neglected theme of citizenship. It examines the changing role of citizens; their rights, obligations and responsibilities as members of nation-states and the issue of accountability in a global society. Using this interdisciplinary approach, the book offers an innovative collection of work from Robert A. Beauregard, Anna Bounds, Janine Brodie, Richard Dagger, Gerard Delanty, Judith A. Garber, Robert J. Holton, Warren Magnusson, Raymond Rocco, Nikolas Rose, Evelyn S. Ruppert, Saskia Sassen, Bryan S. Turner, John Urry, Gerda R. Wekerle and Nira Yuval-Davis

Climate Forcing by the Volcanic Eruption of Mount Pinatubo. Revised edition

We determine the volcano climate sensitivity and response time for the Mount Pinatubo eruption. This is achieved using observational measurements of the temperature anomalies of the lower troposphere and the aerosol optical density (AOD) in combination with a radiative forcing proxy for AOD. Using standard linear response theory we find sensitivity = 0.18 +- 0.04 K/(W/m2), which implies a negative feedback of -1.0 +- 0.4. The intrinsic response time is 5.8+-1.0 months. Both results are contrary to the conventional paradigm that includes long response times and positive feedback. In addition, we analyze the outgoing longwave radiation during the Pinatubo eruption and find that its time dependence follows the forcing much more closely than the temperature, and even has an amplitude equal to that of the AOD proxy. This finding is independent of the response time and feedback results.Comment: 22 pages, including 4 figures. Revised version of a paper [Douglass D. H. and R. S.

Is Citizenship Still Relevant? State Sovereignty, Migration, and Sanctuary Cities in a Globalizing World

This paper argues that sanctuary cities and sanctuary policies in the United States are a manifestation of the conflicts resulting from processes of globalization, which have changed traditional notions of citizenship, state sovereignty, and state security, as well as fostered a cultural backlash and identity politics within the U.S

The fate of NOx emissions due to nocturnal oxidation at high latitudes: 1-D simulations and sensitivity experiments

The fate of nitrogen oxide pollution during high-latitude winter is controlled by reactions of dinitrogen pentoxide (N2O5) and is highly affected by the competition between heterogeneous atmospheric reactions and deposition to the snowpack. MISTRA (MIcrophysical STRAtus), a 1-D photochemical model, simulated an urban pollution plume from Fairbanks, Alaska to investigate this competition of N2O5 reactions and explore sensitivity to model parameters. It was found that dry deposition of N2O5 made up a significant fraction of N2O5 loss near the snowpack, but reactions on aerosol particles dominated loss of N2O5 over the integrated atmospheric column. Sensitivity experiments found the fate of NOx emissions were most sensitive to NO emission flux, photolysis rates, and ambient temperature. The results indicate a strong sensitivity to urban area density, season and clouds, and temperature, implying a strong sensitivity of the results to urban planning and climate change. Results suggest that secondary formation of particulate (PM2.5) nitrate in the Fairbanks downtown area does not contribute significant mass to the total PM2.5 concentration, but appreciable amounts are formed downwind of downtown due to nocturnal NOx oxidation and subsequent reaction with ammonia on aerosol particles

Multiple disparities: earning inequalities in Lisbon

The aim of this article is to analyse the way in which unequal salaries are related to spatial disparities within the city of Lisbon in a context of economic globalization. It will therefore compare the pay levels of the Lisbon's working population in the different parishes. Lisbon municipality stands out from the rest of Portugal because of workers' higher earnings there. However, the municipality has higher inequality levels than those of the country as a whole. These inequalities are not evenly distributed in the municipality’s parishes

Cloud boundary height measurements using lidar and radar

Using only lidar or radar an accurate cloud boundary height estimate is often not possible. The combination of lidar and radar can give a reliable cloud boundary estimate in a much broader range of cases. However, also this combination with standard methods still can not measure the cloud boundaries in all cases. This will be illustrated with data from the Clouds and Radiation measurement campaigns, CLARA. Rain is a problem: the radar has problems to measure the small cloud droplets in the presence of raindrops. Similarly, few large particles below cloud base can obscure the cloud base in radar measurements. And the radar reflectivity can be very low at the cloud base of water clouds or in large regions of ice clouds, due to small particles. Multiple cloud layers and clouds with specular reflections can pose problems for lidar. More advanced measurement techniques are suggested to solve these problems. An angle scanning lidar can, for example, detect specular reflections, while using information from the radars Doppler velocity spectrum may help to detect clouds during rain.Comment: Reviewed conference contributio
