The role of national parliaments in the EU has been at the centre of a long debate. Since the Maastricht treaty, new powers to the EU level have been accompanied not only by an increasing role of the European Parliament (EP) in the legislative process, but also by a number of declarations and protocols to ensure that national parliaments received the information and documents required to effectively monitor their governments in EU affairs. The Lisbon Treaty extended the guarantees and also included new modes of direct participation. The proper use of the mechanisms in place, namely, the subsidiarity checks, the political dialogue with the Commission and the inter-parliamentary cooperation with the European Parliament, has become of vital importance in view of recent developments in EU economic policy and beyond. The choice for increasing inter-governmentalism in decision-making and the centralisation of the implementing and supervisory powers in the Commission and the Central Bank have raised questions about political accountability and the appropriate involvement of parliaments. However, the extent to which national parliaments should be more involved is also rather controversial. This essay examines the difficulty of defining and addressing the question of the democratic legitimacy in the EU. It examines the role of the national parliaments in the treaties and explores ways in which they can contribute to improving that legitimacy.

The European Council meeting on 7 and 8 February 2013 attracted an unusual level of attention from media and citizens. For a couple of days, Europe played a more important role in national politics and news. Sensation-frenzied media and excited politicians spouted notions of ‘a battle’, ‘winners’, ‘losers’ or ‘striking deals’, as if Europe had gone back to the time when its military powers still conflicted. After more than 24 hours of intense negotiations, the respective Member States leaders left Brussels with ‘good news’ for their citizens. However, those with more Euro-federalist feelings were left with a sense of non-accomplishment and missed opportunities, not only because the EU budget for the first time in history was set for a net decrease, but also because the European Council’s conclusions did not contain any ground-breaking changes to this system. Nevertheless, the European Parliament (EP) immediately reminded Europe about its role and outlined its conditions for further negotiations. Thus, the supporters of a modern and stronger EU budget still see a chance in the consent procedure and hope to shift the focus of the debate from the juste retour spirit to the consideration of the European common good. Is there still a chance for such a shift? What issues are at stake?

‘Leading candidates’ competed for the European Commission Presidency in the campaign for the European elections in May 2014. This element of political contestation poses a challenge to the Union’s institutional design. This article investigates to what extent competing ‘leading candidates’ enhances the process of deliberation and party contestation and thus strengthen the role of European Parliament (EP) party groups. In light of the example of the ‘Progressive Alliance of Socialists and Democrats’ and its ‘leading candidate’, Martin Schulz, it is shown that the election campaign did strive to be EU-wide. However, Schulz’s influence on internal party cohesion and coalition formation remained limited. Therefore the influence of an elected ‘leading candidate’ is regarded as a symbolic act, which could deepen the relationship between the EP and the Commission as well as strengthen the democratic and political standing of both institutions vis-à-vis the European Council.

The objectives of the 2009 Lisbon Treaty (LT) include ways to improve the democratic and international images of the European Union (EU). The focus of the literature has so far focused on the overall treaty impact and on the EU´s international role. This paper considers instead its impact on the question of the democratic accountability of the EU´s Common Foreign and Security Policy (CFSP), including its Common Security and Defence Policy dimension (CSDP). This paper consists of three parts: (1) The first part describes the changes the LT has made for the European Parliament (EP) in terms of its external relations. (2) The second part presents the many deficits that the EU suffers from in its foreign, security and defence policies. (3) The third part offers a preliminary analysis of the recently created Inter-Parliamentary Conference (IPC) on CFSP/CSDP, which in addition to MEPs (EP members) includes parliamentarians from the national EU parliaments. The paper concludes that although the IPC is a positive development in trying to bridge those existing democratic gaps, it remains only a step in the right direction due to the existence of many such deficits in the foreign, security and defence policies of the EU and of its member states.

This paper evaluates which factors influence the European Parliament’s decision-making, based on a case study: the 2012 proposal for a General Data Protection Regulation. Following a ‘competitive testing’ approach, six different hypotheses are successively challenged in order to explain why the EP adopted a fundamental rights- oriented position. The first three factors relate to the internal organization of the EP’s work, i.e. the role played by the lead committee, by the rapporteur and by secretariat officials. The last three factors are external-related, i.e. lobbying activities, outside events and institutional considerations. Based on the empirical findings, it is argued that even though the EP’s position is due to a range of various factors, some of them prove to be more relevant than others, in particular the rapporteur and lead committee’s roles. New institutionalism theories also provide a comprehensive explanation for the EP’s willingness to achieve a fundamental rights oriented outcome.

O Estágio Pedagógico (EP) representa para os professores estagiários uma importante oportunidade para por em prática os conteúdos aprendidos ao longo da sua formação académica, e que servem de base para a sua intervenção enquanto profissional do ensino da Educação Física (EF). Através deste trabalho propomos-mos a apresentar, fundamentar e refletir o EP de EF realizado na Escola Básica dos 2º e 3º Ciclos Dr. Eduardo Brazão de Castro, ao longo do ano letivo 2012/2013. A prática letiva incluiu o planeamento, realização e controlo/avaliação de atividades físicas, da aptidão física e dos conhecimentos relativos aos processos de elevação e manutenção da aptidão física em duas turmas (7º2 e 12º PSI). Este domínio incluiu ainda a construção de um instrumento para a observação de aulas. Para além da atividade letiva, o EP englobou outras atividades, nas quais o papel do professor estagiário foi de grande relevo para a sua concretização. As atividades de integração no meio abrangeram a caracterização da turma, o estudo caso e a ação de extensão curricular, que promoveu a inter-relação entre professores, encarregados de educação e alunos em torno da promoção do desporto na natureza e da multidisciplinaridade. A atividade de intervenção na comunidade escolar destinou-se a toda a comunidade educativa e procurou promover a criação de hábitos de vida saudáveis, o desenvolvimento do espírito crítico, estético, cultural e a interação entre a Escola e a Comunidade. As atividades de natureza científico-pedagógica abordaram o ensino dos desportos de natureza na escola (ação individual) e a realização da avaliação diagnóstica em EF (ação coletiva), com o intuito de contribuir para a formação contínua dos professores de EF da Região. A realização do EP e de todas as atividades que o compõem revelou-se fundamental para a formação contínua do professor, na medida em que contribuiu para a preparação do mesmo para atuar perante múltiplas situações.

O Estágio Pedagógico (EP) surge no âmbito do Mestrado em Ensino de Educação Física nos Ensinos Básico e Secundário e é o culminar de um longo percurso académico, que visa a obtenção de habilitação profissional para a docência. Este Relatório de Estágio teve por objetivos reportar e refletir sobre o conjunto de atividades desenvolvidas no EP: 1) Prática Letiva (PL); 2) Atividade de Intervenção na Comunidade Escolar (AICE), 3) Atividades de Integração no Meio (AIM); e 4) Atividades de Natureza Científico-Pedagógica (ANCP). Este EP foi realizado na Escola Básica e Secundária Gonçalves Zarco (EBSGZ), no ano letivo 2012/2013. A PL permitiu a implementação prática de muitas das competências didáticometodológicas apreendidas durante o percurso académico. As assistências às aulas permitiram observar a intervenção pedagógica dos professores, dando-lhes informações vitais sobre a sua prestação. A AIME foi composta por duas subatividades (“Futzarco 2013” e “GZ Workout Session”) e visou a prática generalizada da atividade física, bem como o convívio entre todos os membros da comunidade escolar. As AIM possibilitaram a aquisição de um maior conhecimento dos alunos e de toda a sua envolvência escolar e familiar, através da realização da Caracterização da Turma. Esta caracterização permitiu identificar uma aluna que apresentava fracos índices de aptidão física, sendo posteriormente convidada para participar no Estudo de Caso. A Atividade de Extensão Curricular, denominada “Zarco Sem Fronteiras” visou a envolvência de todos os elementos do processo educativo da turma. As ANCP centraram-se, nomeadamente, nos Sistemas Competitivos e na Avaliação dos Jogos Desportivos Coletivos e visaram sobretudo a partilha de conhecimentos entre os professores de Educação Física das várias escolas da Região Autónoma da Madeira. O EP foi deveras enriquecedor ao nível da evolução das práticas pedagógicas e permitiu a aquisição de competências que serão muito úteis num futuro profissional.

During the Arctic Coring Expedition (ACEX), a 428-m-thick sequence of Upper Cretaceous to Quaternary sediments was penetrated. The mineralogical composition of the upper 300 m of this sequence is presented here for the first time. Heavy and clay mineral associations indicate a major and consistent shift in provenance, from the Barents-Kara - western Laptev Sea region, characterized by presence of common clinopyroxene, to the eastern Laptev-East Siberian seas in the upper part of the section, characterized by common hornblende (amphibole). Sea ice originating from the latter source region must have survived at least one summer melt cycle in order to reach the ACEX drill site, if considering modern sea ice trajectories and velocities. This shift in mineral assemblages probably represents the onset of a perennial sea ice cover in the Arctic Ocean, which occurred at about 13 Ma, thus suggesting a coeval freeze in the Arctic and Antarctic regions.

The paper reports results of a study of clastic heavy mineral assemblages and geochemical features of some assemblages in several Permian-Mesozoic cherty and siliceous-clayey sequences of the Sikhote Alin Region. They are composed of pelagic and hemipelagic sediments of the Panthalassa (Paleopacific) Ocean. Four typical mineral assemblages and their environments are established. In one of the ocean segments, where the sedimentary cover formed during Late Paleozoic - Early Cretaceous, the Permian pelagic domain was characterized by the amphibole-pyroxene assemblage with heavy minerals derived from ophiolites. The Triassic-Jurassic stage was marked by development of the clinopyroxene assemblage with heavy minerals derived from intraplate alkaline volcanic complexes. Middle-Late Jurassic hemipelagic sediments host the zircon-clinopyroxene assemblage with greater role of continental environments and presence of volcanic products of the convergence zone. Another segment of the ocean accumulated red cherts and siliceous-clayey sediments during Jurassic - Early Cretaceous under influence of island-arc volcanism.

In summer 2006 integrated geological, geochemical, hydrological, and hydrochemical studies were carried out in the relict anoxic Mogil'noe Lake (down to 16 m depths) located in the Kil'din Island in the Barents Sea. Chemical and grain size compositions of bottom sediments from the lake (permanently anoxic basin) and from the Baltic Sea deeps (periodically anoxic basins) were compared. Vertical location of the hydrogen sulfide layer boundary in the lake (9-11 m depths) was practically the same from 1974 up to now. Concentrations of suspended matter in the lake in June and July 2006 appeared to be close to its summer concentrations in seawater of the open Baltic Sea. Muds from the Mogil'noe Lake compared to those of the Baltic Sea deeps are characterized by fluid and flake consistency and by pronounced admixtures of sandy and silty fractions (probably of eolic origin). Lacustrine mud contains much plant remains; iron sulfides and vivianite were also found. Concentrations of 22 elements determined in lacustrine bottom sediments were of the same levels as those found here 33 years ago. Concentrations also appeared to be close to those in corresponding grain size types of bottom sediments in the Baltic Sea. Low C_org/N values (aver. 5.0) in muds of the Mogil'noe Lake compared to ones for muds of the Baltic Sea deeps (aver. 10) evidence considerable planktogenic component in organic matter composition of the lacustrine muds. No indications were reveled for anthropogenic contaminations of the lacustrine bottom sediments with toxic metals.

Mineralogical and granulometric properties of glacial-marine surface sediments of the Weddell Sea and adjoining areas were studied in order to decipher spatial variations of provenance and transport paths of terrigenous detritus from Antarctic sources. The silt fraction shows marked spatial differences in quartz contents. In the sand fractions heavy-mineral assemblages display low mineralogical maturity and are dominated by garnet, green hornblende, and various types of clinopyroxene. Cluster analysis yields distinct heavy-mineral assemblages, which can be attributed to specific source rocks of the Antarctic hinterland. The configuration of modern mineralogical provinces in the near-shore regions reflects the geological variety of the adjacent hinterland. In the distal parts of the study area, sand-sized heavy minerals are good tracers of ice-rafting. Granulometric characteristics and the distribution of heavy-mineral provinces reflect maxima of relative and absolute accumulation of ice-rafted detritus in accordance with major iceberg drift tracks in the course of the Weddell Gyre. Fine-grained and coarse-grained sediment fractions may have different origins. In the central Weddell Sea, coarse ice-rafted detritus basically derives from East Antarctic sources, while the fine-fraction is discharged from weak permanent bottom currents and/or episodic turbidity currents and shows affinities to southern Weddell Sea sources. Winnowing of quartz-rich sediments through intense bottom water formation in the southern Weddell Sea provides muddy suspensions enriched in quartz. The influence of quartz-rich suspensions moving within the Weddell Gyre contour current can be traced as far as the continental slope in the northwestern Weddell Sea. In general, the focusing of mud by currents significantly exceeds the relative and absolute contribution of ice-rafted detritus beyond the shelves of the study area.

Lithological horizons have been distinguished in sediments cores from different parts of the Sea of Okhotsk based on primary descriptions of sediments and smear slides, and analyses of contents of both calcium carbonate and organic carbon, and opal. Sediment lithology has been correlated with oxygen isotope records and the standard isotope scale and radiocarbon data by AMS method for three cores studied in detail. This allowed to determine in detail periods of carbonaceous and diatomaceous ooze accumulation in the Sea of Okhotsk. Changes in magnetic susceptibility and grain size composition of sediments have been also compared with oxygen-isotope curves and radiocarbon datings. Obtained results confirm that variations in magnetic susceptibility are related with oxygen-isotope stages and influenced by climatic changes. Tephra interlayers K0, TR, K2, K3 have been identified by mineralogical analyses in all studied cores. Stratigraphic location of these tephra interlayers in detailed studied cores and their radiocarbon ages (8.1, 8.05, 26.8, and about 60 ka, respectively) provided base correlation between the interlayers and volcanic eruptions on the Kamchatka Peninsula and the Kuril Islands. This allows to use the former ones as time markers for deep-sea sediments of the Sea of Okhotsk. New lithostratigraphic and tephrochronologic data obtained allowed to correlate Upper Quaternary sediments from the Sea of Okhotsk.

The Middle Valley segment at the northern end of the Juan de Fuca Ridge is a deep extensional rift blanketed with 200-500 m of Pleistocene turbiditic sediment. Sites 857 and 858 were drilled during Ocean Drilling Program Leg 139 to determine whether these two sites were hydrologically linked end members of an active hydrothermal circulation system. Site 858 was placed in an area of active hydrothermal discharge with fluids up to 270°C venting through anhydrite-bearing mounds on top of altered sediment. The shallow basement of fine-grained basalt that underlies the vents at Site 858 is interpreted as a seamount that was subsequently buried by turbidites. Site 857 was placed 1.6 km south of the Site 858 vents in a zone of high heat flow and numerous seismically imaged ridge-parallel faults. Drilling at Site 857 encountered sediments that are increasingly altered with depth and that overlie a series of mafic sills at depths of 460-940 m below sea floor. Sill margins and adjacent baked sediment are highly altered to magnesian chlorite and crosscut with veins filled with quartz, chlorite, sulfides, epidote, and wairakite. The sill interiors vary from slightly altered, with unaltered plagioclase and clinopyroxene in a mesostasis replaced by chlorite, to local zones of intense alteration and brecciation. In these latter zones, the sill interiors are pervasively replaced by chlorite, epidote, quartz, pyrite, titanite, and rare actinolite. The most complete replacement is associated with brecciated horizons with low recovery and slickensides on fracture surfaces, which we interpret as intersections between faults and the sills. Geochemically, the alteration of the sill complex is reflected in significant whole-rock depletions in Ca, Sr, and Na with corresponding enrichments in Mg, Al, and most metals. The latter results from the formation of conspicuous sulfide poikiloblasts. In contrast, metamorphism of the Site 858 seamount includes incomplete albitization of plagioclase phenocrysts and replacement of sparse mafic phenocrysts. Much of the basement alteration at Site 858 is confined to crosscutting veins except for a highly altered and veined horizon at the contact between basaltic basement and the overlying sediment. The sill complex at Site 857 is more highly depleted in 18O (d18O = 2.4 per mil - 4.7 per mil) and more pervasively replaced by secondary minerals relative to the extrusives at Site 858 (d18O = 4.5 per mil - 5.5 per mil). There is no evidence of significant albitization of the plagioclase at Site 857, suggesting high Ca/Na in the pore fluids. Fluid-inclusion data from hydrothermal minerals in altered mafic rocks and veins at Sites 857 and 858 show a consistency of homogenization temperatures, varying from 245 to 270°C, which is within the range of temperatures observed for the fluids venting at Site 858. The consistency of the fluid inclusion temperatures, the lack of albitization within the Site 857 sills, and the apparently low water/rock ratio collectively suggest that the sill complex at Site 857 is in thermal equilibrium and being altered by a highly evolved Ca-rich fluid similar to the fluids now venting at Site 858. The alteration evident in these two deep crustal drillsites is a result of the ongoing hydrothermal circulation and is consistent with downhole logging results, instrumented borehole results, and hydrothermal fluid chemistry. The pervasive alteration of the laterally extensive sill-sediment complex at Site 857 determines the chemistry of the fluids that are venting at Site 858. The limited alteration of the Site 858 lavas suggests that this basement edifice acts as a penetrator or ventilator for the regional hydrothermal reservoir with much of the flow focussed at the highly altered and veined sediment-basalt contact.

Fine-grained clay subfractions (SFs) with particle size of <0.1, 0.1-0.2, 0.2-0.3, 0.3-0.6, 0.6-2.0, and 2-5 µm separated from claystone of Upper Precambrian Pumanskaya and Poropelonskaya formations on the Srednii Peninsula were studied by transmission electron microscopy, X-ray diffraction, and Rb-Sr methods. All subfractions consist of low-temperature illite and chlorite, and contribution of chlorite decreases with diminishing particle size. The crystallinity index and I002/I001 ratio increase from coarse- to fine-grained SFs. Leaching by ammonium acetate solution and Rb-Sr systematics in combination with mineralogical and morphological data indicate that illite in Upper Proterozoic claystone from the Srednii Peninsula formed during three time intervals: 810-830, 610-620, and about 570 Ma ago. The first generation of this mineral with low Rb/Sr ratio dominates in coarse-grained SFs while the second and third generations with a high Rb/Sr ratio prevail in fine-grained SFs. All of three generations are known in Poropelon claystone, whereas Puman claystone contains only illite of the first and second generations. Geological processes responsible for multistage illite evolution in claystones are discussed.

The Middle Paleozoic complex consists of terrigenous and volcanogenic materials metamorphized in greenschist facies. Clastic rocks have arkosic composition and are formed by alteration of basalts and metamorphic rocks. Metaeffusives were formed from basaltoid products of oceanic tholeiite magma indicating that underwater rise structures of the northern Sea of Japan were emplaced on the oceanic crust.
