Mapping competitiveness with European data. Bruegel Blueprint 23, 6 March 2015

Europe needs improved competitiveness to escape the current economic malaise, so it might seem surprising that there is no common European definition of competitiveness, and no consensus on how to consistently measure it. To help address this situation, this Blueprint provides an inventory and an assessment of the data related to the measurement of competitiveness in Europe. It is intended as a handbook for researchers interested in measuring competiveness, and for policymakers interested in new and better measures of competitiveness. MAPCOMPETE has been designed to provide an assessment of data opportunities and requirements for the comparative analysis of competitiveness in European countries at the macro and the micro level.

Indigenous Peoples’ Rights and their (new) Mobilizations in Russia. EDAP 2/2015

Issues concerning indigenous peoples (IPs) in Russia have become a “hot topic” despite the fact that they represent only 0.2 percent of the population. Constant amendments to the laws affecting the life of IPs and lawsuits filed before local Courts denouncing the violations of IPs’ rights are signs of the struggle surrounding these indigenous peoples. Moreover, between 2012 and 2013, the Russian Association of Indigenous Peoples of the North (RAIPON), the umbrella organization of IPs in the country, was ordered to shut down and subsequently given the permission to reopen by the Russian Ministry of Justice within the course of less than six months. This article aims to gain a deeper understanding of the recent developments vis-à-vis indigenous peoples’ legal protection and IPs’ increasing efforts to exercise their rights.

Turkish Stream and its implications for the EU. European Policy Brief No. 34, March 2015

“A first assessment is that this would not work”, EC Vice-President in charge of Energy Union Mr. Maros Sefcovic said in an interview with The Wall Street Journal at the World Economic Forum in Davos on the 22nd of January. He was commenting on the recent announcement by President Vladimir Putin and Gazprom’s Alexei Miller. Indeed, the Russian gas giant’s CEO announced that South Stream would be replaced by a new project, Turkish Stream, linking Russia to the European part of Turkey and this in addition to the existing 16 billion cubic meters (bcm) Blue stream. This policy brief looks at the various implications this new reality could have for Europe’s energy security.

spotlight europe #2015/02—July 2015: A Gulf CSC Could Bring Peace and Greater Security to the Middle East

Wars continue to ravage in Syria, Iraq and Yemen. Refugees are wandering around aimlessly in the Middle East with many fleeing to Europe. Saudi Arabia and Iran are adding fuel to the flames. They are vying for supremacy while remaining highly suspicious of each other. A Conference for Security and Cooperation could help to ease existing tensions. Many years ago the CSCE was a resounding success. It could thus serve as a blueprint with the nuclear agreement with Iran as a starting point of such a venture.

EU-Iran Relations after the Nuclear Deal.

The signing of the Joint Comprehensive Plan of Action between Iran and global powers in July 2015 was a major turning point in the emerging strategic landscape of the Middle East. The ‘nuclear deal’ led to the lifting by the EU and the US of nuclear-related sanctions, and is now operational. Other sanctions remain in place, however. Nevertheless, unhindered by US competition, European trade delegations have entered into a latter-day gold rush, led by the promise of the biggest untapped market in the world. As such, the EU has both an opportunity and a responsibility to help Iran reintegrate properly into the international system. But, in the face of an opaque clerical regime that relies on internal repression and military business conglomerates, Europe stands to lose if it continues to pursue its uncalculated and uncoordinated approach towards the Islamic Republic. This report offers recommendations to guide the EU towards a comprehensive EU strategy for relations with Iran. It maintains that there is no other option but to keep universal values and the rule of law at the core of the emerging bilateral relationship. In fact, the protection of the economic rights of European traders and investors allows the EU to push for wider reforms and the normalisation of relations.

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.

Uma exploração visual da narrativa fantástica As aventuras de João Sem Medo

Este projecto pretende ser o resultado de um exercício exploratório sobre a fusão entre três temáticas principais - surrealismo, colagem e fantástico - e as potencialidades interpretativas que daí advêm. Apoia-se no 'romance planfetário' As aventuras de João Sem Medo de José Gomes Ferreira, uma obra que, atenta à realidade social e apoiada em eventos históricos, apresenta matéria literária sustentada no universo maravilhoso para discutir os momentos dos quais o autor foi testemunha, propondo reflexões críticas e visões do mundo transformadoras da realidade, questionando verdades estabelecidas e ideias acomodadas. Desta forma, este projecto tem como objectivo a construção de um conjunto de fascículos divertidos e sedutores mas que permaneçam fiéis à ideologia da obra em que se baseia, insistindo constantemente na busca das possibilidades escondidas no familiar.

Sediment and organic matter properties, and molecular formula from sampling locations in the Northern Black Sea

Remineralization of organic matter in reactive marine sediments releases nutrients and dissolved organic matter (DOM) into the ocean. Here we focused on the molecular-level characterization of DOM by high-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) in sediment pore waters and bottom waters from contrasting redox regimes in the northern Black Sea with particular emphasis on nitrogen-bearing compounds to derive an improved understanding of the molecular transformations involved in nitrogen release. The number of nitrogen-bearing molecules is generally higher in pore waters than in bottom waters. This suggests intensified degradation of nitrogen-bearing precursor molecules such as proteins in anoxic sediments: No significant difference was observed between sediments deposited under oxic vs anoxic conditions (average O/C ratios of 0.55) suggesting that the different organic matter quality induced by contrasting redox conditions does not impact protein diagenesis in the subseafloor. Compounds in the pore waters were on average larger, less oxygenated, and had a higher number of unsaturations. Applying a mathematical model, we could show that the assemblages of nitrogen-bearing molecular formulas are potential products of proteinaceous material that was transformed by the following reactions: (a) hydrolysis and deamination, both reducing the molecular size and nitrogen content of the products and intermediates; (b) oxidation and hydration of the intermediates; and (c) methylation and dehydration.
