Challenges for the European Union in times of crisis: reactions

Since the beginning of its existence in the form of communities, this entity faced a lot of challenges that could had been stopped the European dream without the fast, prompt and appropriate reaction of the decision makers. There were a lot of difficult times in its history of more than 60 years but the ambition and need of going forward on the way of integration prevailed and today we can talk about European Union as one of the most important global players, having one of the most complex and fascinating political systems. The tenacity and the willing to succeed off the decision makers made this possible. Moments like “The Empty Chair Crisis“, changes with regards to the decision- making process, convenient for ones but inconvenient for the others, lack of consensus with regards to the new accessions, the big changes that Europe went through in the late 80s etc. showed that the decision makers can have an appropriate response whatever the problem would be and that we must stay together and go on dreaming to a united nation in the form of a federation. Nowadays we are facing maybe the most difficult moment in European Union history. Many of the member states were and still are on the edge. A lot of immediate and prompt actions were taken since the start of financial crisis, either political or economic, drove by the need of going on. We are too much into the integration process, too much dependent one of each other so that we cannot stop and simply go back only to the concept of national state.

Getting the most from public R&D spending in times of budgetary austerity. Bruegel Working Paper 2016/01, February 2016

This working paper reviews the evidence on the impact of public R&D spending. The authors first look at the evidence from micro-analysis of the impact of public intervention on private R&D and innovation, with a focus on the latest results from crosscountry micro-research performed within SIMPATIC. To analyse the impact of public R&D on growth, the micro-results on private R&D investment effects are complemented with a macro-perspective. To this end, the authors look at how public R&D performs in affecting GDP growth and jobs in applied macro-models most commonly used in EU policy analysis. They focus particularly on the NEMESIS model in development within the SIMPATIC project. The authors conclude with some policy recommendations from the reviewed micro and macro SIMPATIC evidence for designing public R&D projects and programmes.

A relevância atual da infografia nos jornais Público e The Times

A infografia é vista constantemente no nosso dia a dia como principal objectivo de nos informar de uma forma gráfica e visual, relativamente a um determinado tema ou momento, trabalhando sempre com informações reais e verdadeiras. O aumento do número e da importância da infografia na comunicação social tem sido exponencial, e notavelmente, a partir das edições online das publicações. Este relatório está dividido em três partes. A primeira tenta enquadrar, muito brevemente, o tema da infografia, a partir de alguns dos melhores exemplos de trabalhos na história da mesma, e explicando a diversidade de géneros de infografia existentes, para além da infografia jornalística. A segunda parte deste relatório, o seu corpo principal, visa a apresentação e divulgação de um projeto de investigação centrado na compreensão do papel da infografia nos jornais Público e The Times, e quais os caminhos que se abrem face às novas tecnologias, em mutação constante. Este estudo assenta principalmente na minha experiência no jornal Público e é comprovado por entrevistas realizadas a Joaquim Guerreiro, Diretor da secção de infografia deste jornal, Mário Cameira, Jornalista visual no jornal The Times, e Ricardo Garcia, o jornalista mais participativo na infografia do jornal Público. Na última parte, faz-se uma breve apresentação e descrição do trabalho desenvolvido durante os seis meses de estágio, apresentando algumas infografias feitas durante este período.

Drift distances, times and primary grain sources of the Arctic Ocean, Exp302 (ACEX)

Knowledge of the long-term history of the perennial ice is an important issue that has eluded study because the Cenozoic core material needed has been unavailable until the recent Arctic Coring Expedition (ACEX). Detrital Fe oxide mineral grains analyzed by microprobe from the last 14 Ma (164 m) of the ACEX composite core on the Lomonosov Ridge were matched to circum-Arctic sources with the same mineral and 12-element composition. These precise source determinations and estimates of drift rates were used to determine that these sand grains could not be rafted to the ACEX core site in less than a year. Thus the perennial ice cover has existed since 14 Ma except for the unlikely rapid return to seasonal ice between the average sampling interval of about 0.17 Ma. Both North America and Russia contributed significant Fe grains to the ACEX core during the last 14 Ma.

Chemical observations in the Red Sea and the inner Gulf of Aden during the International Indian Ocean Expedition 1964/65

The Red Sea has a special place among the adjacent seas of the world. High evaporation, exclusion of its deep water from contact with the Indian Ocean proper and complete absence of continental drainage may result special conditions of the chemistry of the Red Sea. This paper aims to describe and explain the peculiarity of the hydrochemical situation. The influence of the topography, of the inflow and outflow through the straights of Bab el Mandeb, of the evaporation, of the stability of the water layers, and of the circulation will be studied. An attempt is made to estimate the apparent oxygen ultilisation in order to obtain an indication of the biological activity. A further attempt is made toward the quantitative estimation of the circulation of the nutrients and also to obtain some information about transport, dissolution, and precipitation of calcium carbonate. The basis of these investigations are mainly observations of R. V. "Meteor" during the International Indian Ocean Expedition 1964/65. The determination of dissolved oxygen, dissolved inorganic phosphate, nitrate, nitrite, ammonia, pH, alkalinity, silicate as well as salinity and temperature forms the necessary basis for such an investigation of the chemical conditions. In the first chapter the methods and some modifications for the determination of the chemical properties as applied during the I.I.O.E. cruise of R. V. "Meteor" are described. The new methods, as worked out and tested under sea going conditions during several years by the author, are described in more detail. These are the methods for nitrate, silicate, the automatic determination of dissolved inorganic phosphate and silicate, the automated determination of total phosphorus, the in situ recording of the oxygen tension, and the modification for the determination of ammonia, calcium, and dissolved oxygen. With these revised methods more than 18,000 determinations have been carried out during the Indian Ocean cruise. The complete working up of the chemical data of the Indian Ocean Expedition of R. V. "Meteor" is devided into four sections: Contributions 1) to the Chemistry of the Red Sea and the Inner Gulf of Aden, 2) to the Gulf of Aden and the Somali Coast Region, 3) to the Western Indian Coast Region, and 4) to the Persian Gulf and the Straits of Oman. This paper presents the first contribution. The special hydrographical conditions are discussed. It can be shown, that the increase of salinity in the surface waters from the south to the north of the Red Sea is only to about 30 % due to evaporation. The remaining increase is presumed to be due to the admixture of deep water to the surface layers. A special rate for the consumption of oxygen (0.114 ml/ l/a) is derived for the deep water of the Red Sea at 1500 m. Based upon the distribution of the dissolved oxygen along the axii of the Red Sea, a chematic model for the longitudinal circulation of the Red Sea is constructed. This model should be considered as a first approximation and may explain the special distribution of phosphate, nitrate, and silicate. Based upon the evaluation of the residence time of the deep water a dissolution rate for silicate is estimated as 1 mygat/a. It seems possible to calculate residence times of water masses outside the Red Sea from the silicate content. The increase of silicate and the consumption of oxygen lead to residence times of the water below the thermocine of 30 to 48 years. The distribution of oxygen in the Straits of Bab el Mandeb is described and discussed. The rate of consumption of the oxygen in the outflowing Red Sea water is estimated to 8.5 ml/ l/a. This rather high rate is explained with reference to the special conditions in the outflowing water. The Red Sea water is characterized initially by a relative high content of oxygen and a low content of nutrients. The increase in nutrients and the decrease in the oxygen content is a secondary process of the Red Sea water on its way to the Arabian Sea. Based upon the vertical distribution of the dissolved inorganic phosphate vertical exchange coefficients of 1 - 4 g/cm/sec and vertical current speeds of 10**-5 to 10**-4 cm/sec are calculated for some stations in the Red Sea. The distribution of phosphate, silicate, nitrate, nitrite and ammonia for the Red Sea and the Straits of Bab el Mandeb are discussed. The special circulation is evaluated and the balance of the nutrients is estimated by means of the brutto transport. The nutrient deficit is assumed to be balanced by sporadic inflow of intermediate water from the Gulf of Aden. An example for such an inflow has been observed and is demonstrated. The silicate-salinity relationships are a suitable way for characterizing water masses in the Red Sea. Equations for the calculation of the different components from the carbonate system, the ion activities, and the calcium carbonate saturation are evaluated. The influence of temperature and pressure is taken into account. The carbonate saturation is calculated from the determined concentrations of calcium, alkalinity, and the hydrogen ion activity. Saturation values of 320 % are found for the surface layer and of 100% ± 1 for the deep water. The extraordinary equilibrium conditions may explain the constant Ca/Cl ratio and also the sedimentation of undissolved carbonate skelecons even in greater depths. A main sedimentation rate of 2 * 10**-3cm/year is evaluated from a total sedimentation of 10 * 106 to/a of calcium carbonate in the Red Sea. The appendix contains those data, which are not published in the data volume of the I.I.O.E. expedition of R. V. "Meteor".
