Ice-Core Based Assessment of Historical Anthropogenic Heavy Metal (Cd, Cu, Sb, Zn) Emissions in the Soviet Union

The development of strategies and policies aiming at the reduction of environmental exposure to air pollution requires the assessment of historical emissions. Although anthropogenic emissions from the extended territory of the Soviet Union (SU) considerably influenced concentrations of heavy metals in the Northern Hemisphere, Pb is the only metal with long-term historical emission estimates for this region available, whereas for selected other metals only single values exist. Here we present the first study assessing long-term Cd, Cu, Sb, and Zn emissions in the SU during the period 1935–1991 based on ice-core concentration records from Belukha glacier in the Siberian Altai and emission data from 12 regions in the SU for the year 1980. We show that Zn primarily emitted from the Zn production in Ust-Kamenogorsk (East Kazakhstan) dominated the SU heavy metal emission. Cd, Sb, Zn (Cu) emissions increased between 1935 and the 1970s (1980s) due to expanded non-ferrous metal production. Emissions of the four metals in the beginning of the 1990s were as low as in the 1950s, which we attribute to the economic downturn in industry, changes in technology for an increasing metal recovery from ores, the replacement of coal and oil by gas, and air pollution control.

How the Euro divides the union: the effect of economic adjustment on support for democracy in Europe

As often pointed out in the literature on the European debt crisis, the policy programme of austerity and internal devaluation imposed on countries in the Eurozone's periphery exhibits a lack of democratic legitimacy. This article analyses the consequences these developments have for democratic support at both the European and national levels. We show that through the policies of economic adjustment, a majority of citizens in crisis countries has become ‘detached’ from their democratic political system. By cutting loose the Eurozone's periphery from the rest of Europe in terms of democratic legitimacy, the Euro has divided the union, instead of uniting it as foreseen by its architects. Our results are based on aggregated Eurobarometer surveys conducted in 28 European Union (EU) member states between 2002 and 2014. We employ quantitative time-series cross-sectional regression analyses. Moreover, we estimate the causal effect of economic adjustment in a comparative case study of four cases using the synthetic control method.

Tracing the Evidence: The Use of Evaluation Results in Direct-Democratic Campaigns

Although research on direct-democratic campaigns in Switzerland has intensified in the last decade, detailed information on the use of evidence in campaigns is still lacking. Our research aims to contribute both to research on direct democracy and to research on evidence-based policy making, by analyzing how evaluation results are used in directdemocratic campaigns. In this conceptual paper, the formulation of our hypothesis is based on a model of evaluation influence that traces the different uses of evaluation results in the process of a direct-democratic campaign. We assume that the policy analytical capacity of individual members in parliament, government and administration in the (pre)-parliamentary process fosters the use of evidence in campaigns. In the course of the campaign, symbolic use of evaluation in the form of justification, persuasion or mobilization prevails. We assume that the media is an important player in making transparent how political actors use evidence to support their positions. Evidence itself often remains ambiguous and uncertain, and evaluations are influenced by the values of the evaluator. To be able to make the right decisions, therefore, citizens should learn about possible interpretations in argumentative processes. For us, the context of direct democracy in Switzerland provides the setting for such a discourse that, besides evidence, brings up different opinions, values and beliefs.

Democratic Legitimation of Trade Policy Tomorrow: TTIP, Democracy and Market in the Swiss Constitution

Free Trade Agreements (FTAs) are increasingly more concerned with regulatory convergence, rather than trade liberalisation through elimination of tariffs. This appears to result more often in so-called dynamic trade agreements, which still evolve after adoption. Further economic integration in democracies, however, depends on the support of the constituency. This article takes a closer look at the democratic legitimation of global economic integration in a case study on Switzerland. It finds that the current principles and institutions of democracy in Switzerland are unlikely to fully accommodate the new regulatory challenges of dynamic FTAs.

Does Satisfaction with Democracy really increase Happiness? Direct Democracy and Individual Satisfaction in Switzerland

This paper takes the influential “direct democracy makes people happy”-research as a starting point and asks whether direct democracy impacts individual satisfaction. Unlike former studies we distinguish two aspects of individual satisfaction, namely satisfaction with life (“happiness”) and with how democracy works. Based on multilevel analysis of the 26 Swiss cantons we show that the theoretical assumption on which the happiness hypothesis is based has to be questioned, as there is very little evidence for a robust relationship between satisfaction with democracy and life satisfaction. Furthermore, we do not find a substantive positive effect of direct democracy on happiness. However, with respect to satisfaction with democracy, our analysis shows some evidence for a procedural effect of direct democracy, i.e. positive effects related to using direct democratic rights, rather than these rights per se.

Relation of white matter anisotropy to visual memory in 17 healthy subjects

We performed a Rey visual design learning test (RVDLT) in 17 subjects and measured intervoxel coherence (IC) by DTI as an indication of connectivity to investigate if visual memory performance would depend on white matter structure in healthy persons. IC considers the orientation of the adjacent voxels and has a better signal-to-noise ratio than the commonly used fractional anisotropy index. Voxel-based t-test analysis of the IC values was used to identify neighboring voxel clusters with significant differences between 7 low and 10 high test performers. We detected 9 circumscribed significant clusters (p< .01) with lower IC values in low performers than in high performers, with centers of gravity located in left and right superior temporal region, corpus callosum, left superior longitudinal fascicle, and left optic radiation. Using non-parametric correlation analysis, IC and memory performance were significantly correlated in each of the 9 clusters (r< .61 to r< .81; df=15, p< .01 to p< .0001). The findings provide in vivo evidence for the contribution of white matter structure to visual memory in healthy people.

Global warming in an independent record of the past 130 years

The thermometer-based global surface temperature time series (GST) commands a prominent role in the evidence for global warming, yet this record has considerable uncertainty. An independent record with better geographic coverage would be valuable in understanding recent change in the context of natural variability. We compiled the Paleo Index (PI) from 173 temperature-sensitive proxy time series (corals, ice cores, speleothems, lake and ocean sediments, historical documents). Each series was normalized to produce index values of change relative to a 1901–2000 base period; the index values were then averaged. From 1880 to 1995, the index trends significantly upward, similar to the GST. Smaller-scale aspects of the GST including two warming trends and a warm interval during the 1940s are also observed in the PI. The PI extends to 1730 with 67 records. The upward trend appears to begin in the early 19th century but the year-to-year variability is large and the 1730–1929 trend is small.

A global historical ozone data set and prominent features of stratospheric variability prior to 1979

We present a vertically resolved zonal mean monthly mean global ozone data set spanning the period 1901 to 2007, called HISTOZ.1.0. It is based on a new approach that combines information from an ensemble of chemistry climate model (CCM) simulations with historical total column ozone information. The CCM simulations incorporate important external drivers of stratospheric chemistry and dynamics (in particular solar and volcanic effects, greenhouse gases and ozone depleting substances, sea surface temperatures, and the quasi-biennial oscillation). The historical total column ozone observations include ground-based measurements from the 1920s onward and satellite observations from 1970 to 1976. An off-line data assimilation approach is used to combine model simulations, observations, and information on the observation error. The period starting in 1979 was used for validation with existing ozone data sets and therefore only ground-based measurements were assimilated. Results demonstrate considerable skill from the CCM simulations alone. Assimilating observations provides additional skill for total column ozone. With respect to the vertical ozone distribution, assimilating observations increases on average the correlation with a reference data set, but does not decrease the mean squared error. Analyses of HISTOZ.1.0 with respect to the effects of El Niño–Southern Oscillation (ENSO) and of the 11 yr solar cycle on stratospheric ozone from 1934 to 1979 qualitatively confirm previous studies that focussed on the post-1979 period. The ENSO signature exhibits a much clearer imprint of a change in strength of the Brewer–Dobson circulation compared to the post-1979 period. The imprint of the 11 yr solar cycle is slightly weaker in the earlier period. Furthermore, the total column ozone increase from the 1950s to around 1970 at northern mid-latitudes is briefly discussed. Indications for contributions of a tropospheric ozone increase, greenhouse gases, and changes in atmospheric circulation are found. Finally, the paper points at several possible future improvements of HISTOZ.1.0.

Harmonised monitoring of antimicrobial resistance in Salmonella and Campylobacter isolates from food animals in the European Union

Many Member States of the European Union (EU) currently monitor antimicrobial resistance in zoonotic agents, including Salmonella and Campylobacter. According to Directive 2003/99/EC, Member States shall ensure that the monitoring provides comparable data on the occurrence of antimicrobial resistance. The European Commission asked the European Food Safety Authority to prepare detailed specifications for harmonised schemes for monitoring antimicrobial resistance. The objective of these specifications is to lay down provisions for a monitoring and reporting scheme for Salmonella in fowl (Gallus gallus), turkeys and pigs, and for Campylobacter jejuni and Campylobacter coli in broiler chickens. The current specifications are considered to be a first step towards a gradual implementation of comprehensive antimicrobial resistance monitoring at the EU level. These specifications propose to test a common set of antimicrobial agents against available cut-off values and a specified concentration range to determine the susceptibility of Salmonella and Campylobacter. Using isolates collected through programmes in which the sampling frame covers all epidemiological units of the national production, the target number of Salmonella isolates to be included in the antimicrobial resistance monitoring per Member State per year is 170 for each study population (i.e., laying hens, broilers, turkeys and slaughter pigs). The target number of Campylobacter isolates to be included in the antimicrobial resistance monitoring per Member State per year is 170 for each study population (i.e., broilers). The results of the antimicrobial resistance monitoring are assessed and reported in the yearly national report on trends and sources of zoonoses, zoonotic agents and antimicrobial resistance.
