The use of new ICTs in trade union protests - five European cases

Despite the interest in the use of new information and communication technologies (ICTs) by trade unions, little is known about how new ICTs have changed trade union protest. In a period of austerity, in which new groups – including labour-related ones – have shown impressive mobilization using social media, we focus on a cross-country approach, looking at the impact of trade union strikes and protest in the public sector. Our findings show that new ICTs are being used at all stages of strike action and union protests in general, but do not allow us to assert that unions have changed the way they act in a fundamental way.

l bilanciamento tra le libertà economiche e i diritti sociali collettivi operato dalla Corte di Giustizia è un contemperamento tra diritti equiordinati?* = The balance between economic freedoms and collective social rights and actions; Court of Justice is a choice between rights equiordinati? Actions by the Court of Justice. WP C.S.D.L.E. “Massimo D’Antona”.INT – 98/2012

In the Viking and Laval judgments and more recently in the Comm. v. Germany ruling, the Court of Justice applied the proportionality test to collective rights, setting a series of restrictions to the exercise of the right to strike and the right to collective bargaining. The way the ECJ balances the economic freedoms and the social rights is indeed very different from that of the Italian Constitutional Court. Unlike the European Union Treaties, the Italian Constitution recognizes an important role to the right to take collective action which has to be connected with article 3, paragraph 2, consequently the right of strike is more protected than the exercise of economic freedoms.

Disclosure of Leniency Materials: A Bridge between Public and Private Enforcement of Antitrust Law. Research Paper in Law 08/2013, December

The disclosure of leniency materials held by competition authorities has recently been under the spot. On the one hand, these documents could greatly help cartel victims to prove the damage and the causation link when filing damage actions against cartelists. On the other hand, future cartelists could be deterred from applying for leniency since damage actions could be brought as a result of the information submitted by themselves. Neither the current legislation nor the case law have attained yet to sufficiently clarify how to deal with this clash of interests. Our approach obviously attempts to strike a balance between both interests. But not only that. We see the current debate as a great opportunity to boost the private enforcement of antitrust law through the positive spillovers of leniency programmes. We hence propose to build a bridge between the public and the private enforcement by enabling a partial disclosure of the documents.

Citizenship in the discourse of Egyptian political parties. EUSpring Working Paper No. 6, June 2015 [also Citizenship Report no. 3]

The concept of citizenship is one of the most complicated in political and social sciences. Its long process of historical development makes dealing with it particularly complicated. Citizenship is by nature a multi-dimensional concept: there is a legal citizenship, referring first to the equal legal status of individuals, for instance the equality between men and women. Legal citizenship also refers to a political dimension, the right to start and/or join political parties, or political participation more broadly. Thirdly, it has a religious dimension relating to the right of all religious groups to equally and freely practice their religious customs and rituals. Finally, legal citizenship possesses a socio-economic dimension related to the non-marginalisation of different social categories, for instance women. All of these dimensions, far from being purely objects of legal texts and codifications, are emerging as an arena of political struggle within the Egyptian society. Citizenship as a concept has its roots in European history and, more specifically, the emergence of the nation state in Europe and the ensuing economic and social developments in these societies. These social developments and the rise of the nation state have worked in parallel, fostering the notion of an individual citizen bestowed with rights and obligations. This gradual interaction was very different from what happened in the context of the Arab world. The emerging of the nation state in Egypt was an outcome of modernisation efforts from the top-down; it coercively redesigned the social structure, by eliminating or weakening some social classes in favour of others. These efforts have had an impact on the state-society relation at least in two respects. First, on the overlapping relation between some social classes and the state, and second, on the ability of some social groups to self-organise, define and raise their demands. This study identifies how different political parties in Egypt envision the multi-dimensional concept of citizenship. We focus on the following elements: Nature of the state (identity, nature of the regime) Liberties and rights (election laws, political party laws, etc.) Right to gather and organise (syndicates, associations, etc.) Freedom of expression and speech (right to protest, sit in, strike, etc.) Public and individual liberties (freedom of belief, personal issues, etc.) Rights of marginalised groups (women, minorities, etc.)

The revision of the Posted Workers Directive: towards a sufficient policy adjustment? EPC Discussion Paper, 20 April 2016

Labour mobility within the European Union continues to be a limited phenomenon. This concerns both long-term intra-EU mobility and more temporary forms of mobility such as posting of workers, i.e. workers posted to another member state in the framework of cross-border service provision. Yet, despite the limited nature of posting, this topic is far from being absent from the public and political debates. Several factors contribute to this. Firstly, a surge in the number of posted workers has been noticed over the recent years and increased attention has therefore been paid to this issue. Quite a few economic sectors, including construction, manufacturing, and social work, are very concerned by this trend. Secondly, several types of abuses have been recorded such as letter-box companies, bogus self-employment and exploitation of the posted workers' vulnerable situation. Thirdly, questions have been raised as to whether the balance struck by the EU legislator in 1996 (when adopting the Posted Workers Directive) between the freedom to provide crossborder services and the workers' social rights is still valid today. These elements highlight the need for a policy adjustment in order to preserve the legitimacy of the citizens' and workers' freedom to move and, to a certain extent, of the social dimension of the European project. In this context, the European Commission published a proposal to revise the 1996 Directive in order to strike a better balance between economic and social rights. But is this proposal sufficient to ensure a level playing field between economic actors and equal treatment between workers? How will this proposal affect the implementation of other EU initiatives aiming to tackle fraud and abuse? What else is needed to address the tensions between the Single Market principles and the EU's social objectives? This discussion paper, published in the context of the Dutch Presidency and the ongoing negotiations of a revised Directive on posted workers, focuses on these questions while proposing some concrete solutions for a fairer policy framework.

Cortical Abnormalities in Adults and Adolescents with Major Depression based on Brain Scans from 20 Cohorts Worldwide in the ENIGMA Major Depressive Disorder Working Group

The neuro-anatomical substrates of major depressive disorder (MDD) are still not well understood, despite many neuroimaging studies over the past few decades. Here we present the largest ever worldwide study by the ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) Major Depressive Disorder Working Group on cortical structural alterations in MDD. Structural T1-weighted brain magnetic resonance imaging (MRI) scans from 2148 MDD patients and 7957 healthy controls were analysed with harmonized protocols at 20 sites around the world. To detect consistent effects of MDD and its modulators on cortical thickness and surface area estimates derived from MRI, statistical effects from sites were meta-analysed separately for adults and adolescents. Adults with MDD had thinner cortical gray matter than controls in the orbitofrontal cortex (OFC), anterior and posterior cingulate, insula and temporal lobes (Cohen’s d effect sizes: −0.10 to −0.14). These effects were most pronounced in first episode and adult-onset patients (>21 years). Compared to matched controls, adolescents with MDD had lower total surface area (but no differences in cortical thickness) and regional reductions in frontal regions (medial OFC and superior frontal gyrus) and primary and higher-order visual, somatosensory and motor areas (d: −0.26 to −0.57). The strongest effects were found in recurrent adolescent patients. This highly powered global effort to identify consistent brain abnormalities showed widespread cortical alterations in MDD patients as compared to controls and suggests that MDD may impact brain structure in a highly dynamic way, with different patterns of alterations at different stages of life.

Structural features in ODP Holes 128-794D and 128-799B

Numerous structural features occur in the Leg 128 cores from the Japan Sea. They include (1) gravity-induced structures such as slump folds, (2) dewatering structures comprising several sets of veins, and (3) larger faults and veins developed in the volcanic basement of the Yamato Basin as well as in the sedimentary rocks of the Oki Ridge and Kita-Yamato Trough. Gravity-induced structures, mainly slumps and associated faults, suggest the existence of paleoslopes and the dominance of gravitational tectonics during the early and middle Miocene, at the Pliocene/Pleistocene boundary, and during the Quaternary. Several types of mud-filled veins having various shapes were observed. These are especially abundant in the middle Miocene siliceous claystones and porcellanites from the Kita-Yamato Trough. They have been interpreted as dewatering conduits that formed preferentially in highly porous, water-saturated diatomaceous muds on a slope, because of episodic loss of sediment strength, collapse of the sediment framework, and consequent fluid migration. The central part of the vein serves once as a fluid conduit, whereas the transition between conduit-controlled and intergranular flow occurs at the branching extremities, with concentration of fines. The likely trigger responsible for the strength loss is seismic activity. Development of these veins, spatially and chronologically linked to small normal microfaults, implies an extensional regime having layer-parallel extension and a local bedding-parallel shear couple, probably the result of gravitational gliding. The brittle fractures found in Yamato Basin basement Hole 794D cores comprise joints, faults, and veins filled with chlorite-saponite, saponite, and calcite. They suggest a likely transpressive to transtensional regime around the early Miocene/ middle Miocene boundary, with a north-northeast-south-southwest compression alternating with a west-northwest-eastsoutheast extension. The faults from Site 799 cores on the Yamato Rise exhibit a prominent early Miocene-middle Miocene extensional environment, a late Miocene-early Pliocene phase of normal and strike-slip faulting, and a final phase that began during the latest Pliocene. Site 798, on the Oki Ridge, reveals faults that recorded a consistent extensional tectonic regime from Pliocene to the Holocene. These data support the pull-apart kinematic model for early Miocene-middle Miocene time, as regarding the stress regime deduced from the Yamato Basin basement fractures. The recent compression known in the eastern margin of the Japan Sea was not documented by compressive structures at any site. The late Miocene-early Pliocene faulting phase corresponds to a major and general reorganization of the stress distribution in the arc area. Evidence for rapid and main subsidence and synsedimentary extension of the Yamato Basin and Yamato Rise areas between 20 and 15 Ma, and the concomitant rotation of southwest Japan, raise the question of links between this opening and the Shimanto Belt collision in southwest Japan, between the arc and the Philippine Sea Plate.

Fluid compositions and mineralogy of precipitates from Mid Atlantic Ridge hydrothermal vents at 4°48'S

The effect of volcanic activity on submarine hydrothermal systems has been well documented along fast- and intermediate-spreading centers but not from slow-spreading ridges. Indeed, volcanic eruptions are expected to be rare on slow-spreading axes. Here we report the presence of hydrothermal venting associated with extremely fresh lava flows at an elevated, apparently magmatically robust segment center on the slow-spreading southern Mid-Atlantic Ridge near 5°S. Three high-temperature vent fields have been recognized so far over a strike length of less than 2 km with two fields venting phase-separated, vapor-type fluids. Exit temperatures at one of the fields reach up to 407°C, at conditions of the critical point of seawater, the highest temperatures ever recorded from the seafloor. Fluid and vent field characteristics show a large variability between the vent fields, a variation that is not expected within such a limited area. We conclude from mineralogical investigations of hydrothermal precipitates that vent-fluid compositions have evolved recently from relatively oxidizing to more reducing conditions, a shift that could also be related to renewed magmatic activity in the area. Current high exit temperatures, reducing conditions, low silica contents, and high hydrogen contents in the fluids of two vent sites are consistent with a shallow magmatic source, probably related to a young volcanic eruption event nearby, in which basaltic magma is actively crystallizing. This is the first reported evidence for direct magmatic-hydrothermal interaction on a slow-spreading mid-ocean ridge.

Detrital zircon geochronology data, petrographic point count data and paleocurrent indicator data of Triassic turbidites in the Nanpanjiang Basin, South China

Triassic turbidites of the Nanpanjiang basin of south China represent the most expansive and voluminous siliciclastic turbidite accumulation in south China. The Nanpanjiang basin occurs at a critical junction between the southern margin of the south China plate and the Indochina, Siamo and Sibumasu plates to the south and southwest. The Triassic Yangtze carbonate shelf and isolated carbonated platforms in the basin have been extensively studied, but silicilastic turbidites in the basin have received relatively little attention. Deciphering the facies, paleocurrent indicators and provenance of the Triassic turbidites is important for several reasons: it promises to help resolve the timing of plate collisions along suture zones bordering the basin to the south and southwest, it will enable evaluation of which suture zones and Precambrian massifs were source areas, and it will allow an evaluation of the impact of the siliciclastic flux on carbonate platform evolution within the basin. Turbidites in the basin include the Early Triassic Shipao Formation and the Middle-Late Triassic Baifeng, Xinyuan, Lanmu Bianyang and Laishike formations. Each ranges upward of 700 m and the thickest is nearly 3 km. The turbidites contain very-fine sand in the northern part of the basin whereas the central and southern parts of the basin also commonly contain fine and rarely medium sand size. Coarser sand sizes occur where paleocurrents are from the south, and in this area some turbidites exhibit complete bouma sequences with graded A divisions. Successions contain numerous alternations between mud-rich and sand-rich intervals with thickness trends corresponding to proximal/ distal fan components. Spectacularly preserved sedimentary structures enable robust evaluation of turbidite systems and paleocurrent analyses. Analysis of paleocurrent measurements indicates two major directions of sediment fill. The northern part of the basin was sourced primarily by the Jiangnan massif in the northeast, and the central and southern parts of the basin were sourced primarily from suture zones and the Yunkai massif to the south and southeast respectively. Sandstones of the Lower Triassic Shipao Fm. have volcaniclastic composition including embayed quartz and glass shards. Middle Triassic sandstones are moderately mature, matrix-rich, lithic wackes. The average QFL ratio from all point count samples is 54.1/18.1/27.8% and the QmFLt ratio is 37.8/ 18.1/ 44.1%. Lithic fragments are dominantly claystone and siltstone clasts and metasedimentary clasts such as quartz mica tectonite. Volcanic lithics are rare. Most samples fall in the recycled orogen field of QmFLt plots, indicating a relatively quartz and lithic rich composition consistent with derivation from Precambrian massifs such as the Jiangnan, and Yunkai. A few samples from the southwest part of the basin fall into the dissected arc field, indicating a somewhat more lithic and feldspar-rich composition consistent with derivation from a suture zone Analysis of detrial zircon populations from 17 samples collected across the basin indicate: (1) Several samples contain zircons with concordant ages greater than 3000 Ma, (2) there are widespread peaks across the basin at 1800 Ma and 2500, (3) a widespread 900 Ma population, (3) a widespread population of zircons at 440 Ma, and (5) a larger population of younger zircons about 250 Ma in the southwestern part which is replaced to the north and northwest by a somewhat older population around 260-290 Ma. The 900 Ma provenance fits derivation from the Jiangnan Massif, the 2500, 1800, and 440 Ma provenance fits the Yunkai massif, and the 250 Ma is consistent with convergence and arc development in suture zones bordering the basin on the south or southwest. Early siliciclastic turbidite flux, proximal to source areas impacted carbonate platform evolution by infilling the basin, reducing accommodation space, stabilizing carbonate platform margins and promoting margin progradation. Late arrival, in areas far from source areas caused margin aggradation over a starved basin, development of high relief aggradational escarpments and unstable scalloped margins.

Composition of Aleutian forearc sediments

The ultimate composition of any sandstone is affected by a host of primary and secondary factors, including the lithologies present in source terranes, climate, depositional environment and diagenesis. In the case of a subduction complex, however, unequivocal identification of detrital provenance may be impossible because of the cumulative effects of tectonic and sedimentary transport. Long-distance sedimentary transport (> 1000 km) is common within trenches, and abyssal-plain turbidites can be tectonically transported for long distances as the underlying oceanic basement drifts towards a subduction front. Post-accretionary displacement can occur as a consequence of strike-slip faulting, and the total distance of tectonic dislocation may reach several thousand kilometers. The present-day Aleutian forearc region (North Pacific Ocean) illustrates many of the "problems" which typify subduction zones. Several petrologic suites can be identified, and there are significant variations in detrital modes in both time and space. The Aleutian region serves as a sobering modern analog for accreted rock units such as the Franciscan Complex of California, where intercalations of discrete sandstone suites have been noted. In the absence of paleomagnetic control, interpretations of sediment provenance within ancient subduction complexes probably should be restricted to the generic level.

Physical models of dilatant normal faulting in jointed cohesive rocks

Dilatant faults often form in rocks containing pre-existing joints, but the effects of joints on fault segment linkage and fracture connectivity is not well understood. We present an analogue modeling study using cohesive powder with pre-formed joint sets in the upper layer, varying the angle between joints and a rigid basement fault. We analyze interpreted map-view photographs at maximum displacement for damage zone width, number of connected joints, number of secondary fractures, degree of segmentation and area fraction of massively dilatant fractures. Particle imaging velocimetry helps provide insights on deformation history of the experiments and illustrate the localization pattern of fault segments. Results show that with increasing angle between joint-set and basement-fault strike the number of secondary fractures and the number of connected joints increases, while the area fraction of massively dilatant fractures shows only a minor increase. Models without pre-existing joints show far lower area fractions of massively dilatant fractures while forming distinctly more secondary fractures.
