Improving decision-making in the EU. CHALLENGE EUROPE Issue 22 - Challenges and new beginnings: Priorities for the EU's new leadership, September 2014.

The multiple crises the European Union (EU) has experienced in recent years have fundamentally altered decision-making and, more broadly, governance in the EU. Pre-crisis systems and processes were not adequate to react to such critical and systemic challenges, but the speed of the crisis meant that new governance mechanisms have been superimposed on existing processes and structures rather than seeing a fundamental reform of decision-making. Consequently, not all changes have been fully successful. Given the institutional changes this year and the ongoing development of the EMU governance framework, now presents a good opportunity to reform EU decision-making.

Necessary desirability: The inherent contradiction in the European system. EuropEos Commentary No. 11, 9 June 2011

In all political systems there is a gap between the rhetoric of electoral programmes and the practical work of institutions, argues author Riccardo Perissich, but the ‘vision thing’ is often a necessary prerequisite to reaching difficult decisions. When it comes to European institutions, which include the member states acting collectively, the desirable vision – the goal of European unity – has always been there and is still very much alive. Also, the existence of a broadly defined political goal has often facilitated agreements that were in fact purely necessary. However, because we lack a pan-European constituency to debate it, the narrative about this goal has been translated into different languages and is all but common. In fact, we have never seriously tried to unify it. Indeed, Europeans stopped debating what is desirable a long time ago: they simply react to events.

EU Sanctions: A Relevant Foreign Policy Tool? EU Diplomacy Paper No. 3, May 2014

This paper examines an instrument which establishes an explicit link between economic power and foreign policy of the European Union (EU): restrictive measures or sanctions. As the EU is increasingly confronted with situations requiring a firm response, sanctions – arguably the EU’s ‘hardest’ tool – have become somewhat of a standard reaction. To what extent are sanctions a relevant tool for EU external action? By looking at several case studies from a set of 47 autonomous EU sanction cases, this paper acknowledges the many internal and external difficulties the EU faces when using the sanctions tool. However, it also shows that despite those challenges, the ‘hard’ and coercive nature of the sanction instrument nevertheless make it a relevant foreign policy tool which allows the EU to react to external crises.

Society's level of literacy: A cross cultural study. ACES Working Papers No. 4, 2008

In this study, the relationship between the country's level of literacy and its national culture will be explored. Cultural differences effect the way that people think and react. Culture is "the value shared amongst distinctive social groups and classes" (Soley and Pandya 2003, 206). House, et al. (2004, 57) define culture as "shared motives, values, beliefs, identities, and interpretations or meanings of significant events that result from common experiences of members of collectives and are transmitted across age generations." Dutch anthropologist Geert Hofstede (1991) considers culture to be "the collective programming of the mind. Culture is a stem of collectively held values" (Hofstede 1981, p. 240).

Federalist rhetoric or political tactics? The what, where, who, when and why of Juncker’s call for a common European army. EPC Commentary, 12 March 2015

In an interview with the German newspaper Welt am Sonntag on 8 March 2015, the President of the European Commission, Jean-Claude Juncker, strongly advocated a common European army to consolidate peace in Europe, react to security threats both within the continent and in its neighbourhood, defend European values vis-à-vis aggressive powers, notably Russia, and create economies of scale by consolidating demand for military equipment.

The Energy Union: what is in a name? EPC Commentary, 18 March 2015

On 19-20 March, the EU Council will react to the Commission’s Communication on the Energy Union. Considering the high expectations, the reactions have been diverse so far, with complaints about the lack of attention for some specific interests or unsurprising credit as the document is vague enough to accommodate all wishes. However, a general consensus has emerged about the need for a holistic approach. States and stakeholders seem to recognise that the main challenges Europe faces in energy matters are deeply interconnected and can no longer be treated separately and without a larger role for the EU.

Germany’s ‘refugee’ problem. The most important test for Chancellor Merkel and the grand coalition. OSW COMMENTARY NUMBER 182/11.09.2015 2015-09-11

The rapid increase in the number of immigrants from outside of the EU coming to Germany has become the paramount political issue. According to new estimates, the number of individuals expected arrive in Germany in 2015 and apply for asylum there is 800,000, which is nearly twice as many as estimated in earlier forecasts. Various administrative, financial and social problems related to the influx of migrants are becoming increasingly apparent. The problem of ‘refugees’ (in public debate, the terms ‘immigrants’, ‘refugees’, ‘illegal immigrants’, ‘economic immigrants’ have not been clearly defined and have often been used interchangeably) has been culminating for over a year. Despite this, it was being disregarded by Angela Merkel’s government which was preoccupied with debates on how to rescue Greece. It was only daily reports of cases of refugee centres being set on fire that convinced Chancellor Merkel to speak and to make immigration problem a priority issue (Chefsache). Neither the ruling coalition nor the opposition parties have a consistent idea of how Germany should react to the growing number of refugees. In this matter, divisions run across parties. Various solutions have been proposed, from liberalisation of laws on the right to stay in Germany to combating illegal immigration more effectively, which would be possible if asylum granting procedures were accelerated. The proposed solutions have not been properly thought through, instead they are reactive measures inspired by the results of opinion polls. This is why their assumptions are often contradictory. The situation is similar regarding the actions proposed by Chancellor Merkel which involve faster procedures to expel individuals with no right to stay in Germany and a plan to convince other EU states to accept ‘refugees’. None of these ideas is new – they were already present in the German internal debate.

Pro-American non-alignment. Sweden and Finland develop closer military co-operation with the United States. OSW COMMENTARY NUMBER 205/31.03.2016

Russia’s increasingly aggressive policy and its enhanced military activity in the Nordic-Baltic region has led to revaluations in Sweden’s and Finland’s security and defence policies and a rethinking of the formats of their military co-operation. While remaining outside NATO, the two states have been developing closer bilateral defence co-operation and working more closely with the United States, while at the same time developing co-operation with NATO. Sweden and Finland perceive the United States as the guarantor of regional and European security. From their point of view, the United States is currently the country that has both the necessary military capabilities and the political will to react in the event of a conflict between Russia and NATO in the Nordic-Baltic region, in which both countries would inevitably become involved despite their non-aligned status. For Sweden and Finland, intensified co-operation with the United States offers an alternative to NATO membership, which is currently out of the question for domestic political reasons. Meanwhile, the US has also become increasingly aware of the strategic importance of the two states, which, for the purposes of contingency planning, are in fact an extension of NATO’s north-eastern flank.

The Multiple Signaling Systems Regulating Virulence in Pseudomonas aeruginosa

Cell-to-cell communication is a major process that allows bacteria to sense and coordinately react to the fluctuating conditions of the surrounding environment. In several pathogens, this process triggers the production of virulence factors and/or a switch in bacterial lifestyle that is a major determining factor in the outcome and severity of the infection. Understanding how bacteria control these signaling systems is crucial to the development of novel antimicrobial agents capable of reducing virulence while allowing the immune system of the host to clear bacterial infection, an approach likely to reduce the selective pressures for development of resistance. We provide here an up-to-date overview of the molecular basis and physiological implications of cell-to-cell signaling systems in Gram-negative bacteria, focusing on the well-studied bacterium Pseudomonas aeruginosa. All of the known cell-to-cell signaling systems in this bacterium are described, from the most-studied systems, i.e., N-acyl homoserine lactones (AHLs), the 4-quinolones, the global activator of antibiotic and cyanide synthesis (GAC), the cyclic di-GMP (c-di-GMP) and cyclic AMP (cAMP) systems, and the alarmones guanosine tetraphosphate (ppGpp) and guanosine pentaphosphate (pppGpp), to less-well-studied signaling molecules, including diketopiperazines, fatty acids (diffusible signal factor [DSF]-like factors), pyoverdine, and pyocyanin. This overview clearly illustrates that bacterial communication is far more complex than initially thought and delivers a clear distinction between signals that are quorum sensing dependent and those relying on alternative factors for their production.

Phosphorus components, trace metals and Ba excess of ODP Site 202-1237 sediments

We determined the sedimentary concentrations of phosphorus (P), barium (Ba), manganese (Mn), titanium (Ti), aluminum (Al), and uranium (U) for sediment samples from the southeast Pacific Nazca Ridge, Ocean Drilling Program Site 1237. This unique record extends to 31 Ma over 360 meters composite depth (mcd), recording depositional history as the site progressed eastward over its paleohistory. We sampled with a temporal resolution of ~0.2 m.y. throughout the sequence, equivalent to an average spacing of 1.63 m/sample. Concentrations of sequentially extracted components of P (oxide-associated, authigenic, organic, and detrital) increase toward the modern. Al/Ti ratios indicate that the background detrital source material is consistent with upper continental crust. U enrichment factors (U EFs) generally exceed crustal values and indicate slightly reducing environments. However, authigenic U precipitation can also be influenced by the organic carbon rain rate and may not be solely an indicator of redox conditions. Dramatic changes in Mn EFs at ~162 mcd, from values between 12 and 93 to values <12 after this depth, and a sharp color contact boundary lead us to believe that a paleoredox boundary from an oxygenated to a more reducing depositional environment occurred near this depth. Estimates of biogenic barite concentrations from a total sediment digestion technique (Ba excess) are greater than those from a barite extraction (Ba barite) for selected samples across the entire depth range. Applying a range of Ba/Ti ratios from different source materials to correct for detrital inputs does not change the lack of agreement with Ba barite concentrations. Reactive P (P reactive) concentrations (the sum of oxide-associated, authigenic, and organic P concentrations) increase toward the modern with values typically <12 µmol P/g from the base of our record through ~100 mcd, with a gradual increase to concentrations >15 µmol P/g. Ba excess follows the same general trends as Preactive, with concentrations <14 µmol Ba/g in the lower portion of the record to values >15 µmol Ba/g. Accumulation rate records of these proxies will be needed to infer paleoproductivity. P reactive/Ba excess ratios, an indicator of the relative burial of the nutrient P to organic carbon export, exhibit higher values, similar to modern, from the base of our record through ~180 mcd. The remainder of the record exhibits values lower than modern, indicating that organic carbon export to the sediments was higher relative to nutrient burial.

Geochemistry of Eocene/Oligocene sediments of ODP Hole 154-925A

Paleoproductivity, nutrient burial, and carbon cycling were investigated across the Eocene/Oligocene (E/O) boundary (begin to end; 36.9-32.7 Ma at ~40 kyr resolution, timescale of Shackleton et al. (1999, doi:10.1098/rsta.1999.0407) at Ocean Drilling Program Site 925 on the Ceara Rise in the western equatorial Atlantic (3040 m present water depth; 748.26-850.70 mbsf). Downcore bulk sediment records of biogenic barium, total reactive phosphorus, biogenic silica, and calcium carbonate are interpreted to represent export production, net nutrient burial, biogenic opal production, and inorganic carbon burial, respectively. The global positive excursion in d13C subsequent to the E/O boundary is recorded at Site 925. Export production appears to have been externally forced by orbital parameters at eccentricity frequencies during the study interval, based on spectral analysis of the biogenic barium and reactive phosphorus records. Biogenic silica production or preservation increased after the Eocene/Oligocene boundary to a higher baseline, although overall productivity and nutrient burial did not increase, based on barium and reactive phosphorus records. Thus, although absolute production did not increase at this site, a shift in relative abundance of siliceous versus carbonate productivity may have resulted in a change in relative organic carbon burial. This may have contributed to the positive excursion in global oceanic d13C subsequent to the Eocene/Oligocene boundary, although the silica maximum persists after the carbon isotope excursion ends.

Age determination and stable isotope records of sediment core M78/1_235-1

Paleoenvironmental studies and climate models demonstrate that fluvial runoff and moisture availability in the Caribbean hinterland react very sensitively to climatic variations. Late Pleistocene and Holocene climate records document pronounced dry and wet periods over tropical South America mainly caused by shifts of the Intertropical Convergence Zone (ITCZ). However, forcing mechanisms for changes in the ITCZ position remain controversial. Here we present high-resolution foraminiferal Ba/Ca and d18Oseawater records from a core located within the Orinoco River outflow documenting abrupt hydrological changes in the Orinoco catchment area during the deglacial and Holocene. Our data, obtained from the surface-dwelling foraminifera Globigerinoides ruber (pink), show an abrupt increase in Ba/Ca ratios in the early Holocene, starting ~600 yr after the end of the Younger Dryas (YD) cold interval at ca. 10.8 ka and suggesting a massive reorganization of moisture sources in northern South America. In contrast, the salinity dependent d18Oseawater from the same samples shows a gradual decrease starting at the end of the YD. The offset of our Ba/Ca peak excludes meltwater release in conjunction with the northern Andean glacier retreat well before the end of the YD as a forcing mechanism. We suggest that the Ba/Ca record documents an abrupt increase in Ba-rich waters of a northern Andean source caused by the insolation-driven shift of the ITCZ and/or enhanced monsoon activity.

Lake sediments from Store Koldewey, Northeast Greenland

A 2.9 m long sedimentary record was studied from a small lake, here referred to as Duck Lake, located at 76°25'N, 18°45'W on Store Koldewey, an elongated island off the coast of Northeast Greenland. The sediments were investigated for their geophysical and biogeochemical characteristics, and for their fossil chironomid assemblages. Organic matter began to accumulate in the lake at 9.1 cal. kyr BP, which provides a minimum age for the deglaciation of the basin. Although the early to mid-Holocene is known as a thermal maximum in East Greenland, organic matter accumulation in the lake remained low during the early Holocene, likely due to late plant immigration and lack of nutrient availability. Organic matter accumulation increased during the middle and late Holocene, when temperatures in East Greenland gradually decreased. Enhanced soil formation probably led to higher nutrient availability and increased production in the lake. Chironomids are abundant throughout the record after 9.1 cal. kyr BP and seem to react sensitively to changes in temperature and nutrient availability. It is concluded that relative temperature reconstructions based on biogeochemical data have to be regarded critically, particularly in the period shortly after deglaciation when nutrient availability was low. Chironomids may be a suitable tool for climatic reconstructions even in those high arctic environments. However, a better understanding of the ecology of chironomids under these extreme conditions is needed.
