Gazprom’s evolving strategy in a new commercial and political context: how should the EU react? EPC Policy Brief, 27 April 2015

After years of unchallenged commercial domination of a sizeable portion of the EU's gas market, Gazprom is confronted with a statement of objections issued on 22 April by the EU Commission for abusing its dominant market position. The company was already prevented from going ahead with its South Stream project aimed at consolidating Gazprom's grip on Southeast Europe's markets by bypassing Ukraine – due to alleged non-compliance of intergovernmental agreements with the EU regulatory framework. Furthermore, it walked away from negotiations that could have allowed it to access more than 50% of the OPAL pipeline – an onshore branch of the offshore Russian German Nord Stream pipeline –, whilst its attempts to go downstream through the acquisition of European distribution and transmission operators, such as Wingas and DESFA, failed due to current political tensions and the risk of a negative Commission ruling on the operation. Does this mean that the Russian gas behemoth – so often portrayed as the energy arm of the Kremlin – is not so powerful after all? This Policy Brief aims to frame the erosion of Gazprom's power in a wider perspective, analysing its peculiar position at a time of transition, with the global gas business going from a sellers' to a buyers' market, and providing recommendations on how Europe should deal with it. It will be argued that Gazprom – despite still being affected by the Kremlin's political priorities – is moving towards more commercially sound behavior. The EU should profit from this evolution without being tempted by mercantilist options, and rather use the political momentum provided by the energy union to remove barriers to solidarity and to increase competition on the trading platforms.

What do Eurozone academics think about EMU reform? On broad support and German exceptionalism. Bruges Political Research Papers 41/2015.

This paper is an empirical contribution to the literature on the formation of policy preferences on Economic and Monetary Union (EMU) reform within its Member States. In the aftermath of the euro crisis, many proposals to ‘complete’ EMU have been tabled. However, discord among Member States has led to a piecemeal restructuring of EMU. For this paper, a survey has been conducted among euro area academic experts, gauging preferences on EMU reform. We find that general consensus masks significant discord among academics from different Member States. Our data indicates the existence of conflicting national epistemic communities, bound by shared causal beliefs on macro-economic policy. Academics within the key creditor Member State, Germany, assume an outlier position. Within the sample of German academics, economists are particularly strongly opposed to all moves in the direction of fiscal or social union. As economists are those academic experts most likely to influence the economic policy beliefs dominant among the German policy elite, these results are highly politically salient. We confront these findings with the literature on the exceptionalism of German economics. We contend that our results substantiate the claim that inadequate EMU reform and, more generally, the EU approach to the Eurozone crisis, can be partially explained by the firm grip these economic doctrines hold over the economics profession and policy-making circles in Germany.

Did Egypt's Parliamentary Election just trump citizens’ rights? Arab Citizenship Review No. 12, 19 November 2015

Since the Muslim Brotherhood rule was toppled in July 2013, the regime of President Abd al-Fattah al-Sisi has strived to consolidate his one-man rule; he painted the political opposition and civil society as traitors and foreign agents and exploited the fight against terrorism to suppress freedom of expression, justify a crackdown on the press, eclipse justice in courtrooms, throw thousands in prison, and tighten his grip on police forces. The regime has postponed parliamentary elections for some time, while it marginalised and weakened the non-Islamist political parties that helped Sisi take power. He did so by promoting electoral lists with candidates who are loyal to the president, to ensure control over the new assembly and by obstructing any political alliance that could form an opposition. At the same time, the security apparatus has been given free rein to control the public sphere and engineer the electoral process. This may ultimately lead to a parliament that includes no advocates for rights and liberties, which is particularly significant since the incoming assembly will review the huge amount of legislation that President Sisi has issued in the absence of a parliament. In addition, shortly before elections, President Sisi raised questions about the constitution, calling for it to be amended to reduce the powers of the parliament and increase those of the president. It is thus clear that Sisi seeks not only to consolidate his regime, without political opposition, but to free his rule of any effective oversight from society or parliament.

Moldova: from oligarchic pluralism to Plahotniuc’s hegemony. OSW Commentary Number 208/07.04.2016

Moldova’s political system took shape due to the six-year rule of the Alliance for European Integration coalition but it has undergone a major transformation over the past six months. Resorting to skilful political manoeuvring and capitalising on his control over the Moldovan judiciary system, Vlad Plahotniuc, one of the leaders of the nominally pro-European Democratic Party and the richest person in the country, was able to bring about the arrest of his main political competitor, the former prime minister Vlad Filat, in October 2015. Then he pushed through the nomination of his trusted aide, Pavel Filip, for prime minister. In effect, Plahotniuc has concentrated political and business influence in his own hands on a scale unseen so far in Moldova’s history since 1991. All this indicates that he already not only controls the judiciary, the anti-corruption institutions, the Constitutional Court and the economic structures, but has also subordinated the greater part of parliament and is rapidly tightening his grip on the section of the state apparatus which until recently was influenced by Filat.

Radiolarian-based paleotemperatures of ODP Site 177-1089 in the Atlantic Sector of the Southern Ocean

Two cores, Site 1089 (ODP Leg 177) and PS2821-1, recovered from the same location (40°56'S; 9°54'E) at the Subtropical Front (STF) in the Atlantic Sector of the Southern Ocean, provide a high-resolution climatic record, with an average temporal resolution of less than 600 yr. A multi-proxy approach was used to produce an age model for Core PS2821-1, and to correlate the two cores. Both cores document the last climatic cycle, from Marine Isotopic Stage 6 (MIS 6, ca. 160 kyr BP, ka) to present. Summer sea-surface temperatures (SSSTs) have been estimated, with a standard error of ca. +/-1.16°C, for the down core record by using Q-mode factor analysis (Imbrie and Kipp method). The paleotemperatures show a 7°C warming at Termination II (last interglacial, transition from MIS 6 to MIS 5). This transition from glacial to interglacial paleotemperatures (with maximum temperatures ca. 3°C warmer than present at the core location) occurs earlier than the corresponding shift in delta18O values for benthic foraminifera from the same core; this suggests a lead of Southern Ocean paleotemperature changes compared to the global ice-volume changes, as indicated by the benthic isotopic record. The climatic evolution of the record continues with a progressive temperature deterioration towards MIS 2. High-frequency, millennial-scale climatic instability has been documented for MIS 3 and part of MIS 4, with sudden temperature variations of almost the same magnitude as those observed at the transitions between glacial and interglacial times. These changes occur during the same time interval as the Dansgaard-Oeschger cycles recognized in the delta18Oice record of the GRIP and GISP ice cores from Greenland, and seem to be connected to rapid changes in the STF position in relation to the core location. Sudden cooling episodes ('Younger Dryas (YD)-type' and 'Antarctic Cold Reversal (ACR)-type' of events) have been recognized for both Termination I (ACR-I and YD-I events) and II (ACR-II and YD-II events), and imply that our core is located in an optimal position in order to record events triggered by phenomena occurring in both hemispheres. Spectral analysis of our SSST record displays strong analogies, particularly for high, sub-orbital frequencies, to equivalent records from Vostok (Antarctica) and from the Subtropical North Atlantic ocean. This implies that the climatic variability of widely separated areas (the Antarctic continent, the Subtropical North Atlantic, and the Subantarctic South Atlantic) can be strongly coupled and co-varying at millennial time scales (a few to 10-ka periods), and eventually induced by the same triggering mechanisms. Climatic variability has also been documented for supposedly warm and stable interglacial intervals (MIS 1 and 5), with several cold events which can be correlated to other Southern Ocean and North Atlantic sediment records.

Observation of ferromanganese deposits in the Baltic Sea

Baltic sediments have been studied by Behrens, Munthe, Küppers, Spethmann, Apstein, Sjöstedt, Pratje and the writer. The following types of sediments have been observed: varved and non-varved late-glacial clays, gray and black, post-glacial muds, and sands. The organic content of late-glacial clays ordinarily is less than 1.3 per cent, and of post-glacial muds more than 3 per cent. Sediments containing intermediate quantities are scarce. This can be explained as a result of the changed balance between organic and inorganic sedimentation when the glacial period ended; the abundance of fresh detritus then suddenly ceased and inorganic sedimentation became very much slower than before; consequently, the relative amount of organic detritus increased. As most of the material was not subjected to biological analysis, it has not been possible to distinguish different ages among post-glacial sediments.

(Table 1) Grain size, sedimentation rates and accumulation rates of ODP Hole 152-919A coarse-sand ice-rafted debris

At mid- to high-latitude marine sites, ice-rafted debris (IRD) is commonly recognized as anomalously coarse-grained terrigenous material contained within a fine-grained hemipelagic or pelagic matrix (e.g., Conolly and Ewing, 1970; Ruddiman, 1977, doi:10.1130/0016-7606(1977)88<1813:LQDOIS>2.0.CO;2; Krissek, 1989, doi:10.2973/odp.proc.sr.104.114.1989; Jansen et al., 1990; Bond et al., doi:10.1038/360245a0, 1992; Krissek, 1995, doi:10.2973/odp.proc.sr.145.118.1995). The presence of such ice-rafted material is a valuable indicator of the presence of glacial ice at sea level on an adjacent continent, whereas the composition of the IRD can often be used to identify the location of the source area (e.g., Goldschmidt, 1995, doi:10.1016/0025-3227(95)00098-J). Because the amount of core recovered during Leg 163 was very limited, this shore-based, postcruise study focuses on materials recovered at a nearby site during Leg 152. In particular, this study examines sediments recovered at Site 919; these sediments were described as containing a significant ice-rafted component in the Leg 152 Initial Reports volume (Larsen, Saunders, Clift, et al., 1994, doi:10.2973/odp.proc.ir.152.1994). In this study, the sedimentary section from Site 919 has been examined with the goal of providing a detailed history of glaciations on Greenland and other landmasses adjacent to the Norwegian-Greenland Sea; this history ultimately will be calibrated using an oxygen isotope stratigraphy (Flower, 1998, doi:10.2973/odp.proc.sr.152.219.1998), although that calibration has not been completed at this time. Because ice-core studies of the Greenland Ice Sheet (GIS) have shown that the GIS changed dramatically, and in some cases extremely rapidly, during at least the last interglacial stage (GRIP Members, 1993, doi:10.1038/364203a0), a detailed IRD record from the Southeast Greenland margin should provide insight into the longer term behavior of this sensitive component of the Northern Hemisphere climate system.

Centennial-scale evolution of Dansgaard-Oeschger events in sediment core MD95-2006

There is much uncertainty surrounding the mechanisms that forced the abrupt climate fluctuations found in many palaeoclimate records during Marine Isotope Stage (MIS)-3. One of the processes thought to be involved in these events is the Atlantic Meridional Overturning Circulation (MOC), which exhibited large changes in its dominant mode throughout the last glacial period. Giant piston core MD95-2006 from the northeast Atlantic Ocean records a suite of palaeoceanographic proxies related to the activity of both surface and deep water masses through a period of MIS-3 when abrupt climate fluctuations were extremely pronounced. A two-stage progression of surface water warming during interstadial warm events is proposed, with initial warming related to the northward advection of a thin warm surface layer within the North Atlantic Current, which only extended into deeper surface layers as the interstadial progressed. Benthic foraminifera isotope data also show millennial-scale oscillations but of a different structure to the abrupt surface water changes. These changes are argued to partly be related to the influence of low-salinity deepwater brines. The influence of deepwater brines over the site of MD95-2006 reached a maximum at times of rapid warming of surface waters. This observation supports the suggestion that brine formation may have helped to destabilize the accumulation of warm, saline surface waters at low latitudes, helping to force the MOC into a warm mode of operation. The contribution of deepwater brines relative to other mechanisms proposed to alter the state of the MOC needs to be examined further in future studies.

Domains of the TGN: Coats, tethers and G proteins

The trans-Golgi network is the major sorting compartment of the secretory pathway for protein, lipid and membrane traffic. There is a constant flow of membrane and cargo to and from this compartment. Evidence is emerging that the trans-Golgi network has multiple biochemically and functionally distinct subdomains, each of which contributes to the combined sorting and transport requirements of this dynamic compartment. The recruitment of distinct arrays of protein complexes to trans-Golgi network membranes is likely to produce the diversity of structure and biochemistry observed amongst subdomains that serve to generate different carriers or maintain resident trans-Golgi network components. This review discusses how these subdomains may be formed and examines the molecular players involved, including G proteins, clathrin adaptors and golgin tethers. Diversity within these protein families is highlighted and shown to be critical for the functionality of the trans-Golgi network, as a mediator of protein sorting and membrane transport, and for the maintenance of Golgi structure.

Performance of the Norwegian version of AUSCAN - a disease-specific measure of hand osteoarthritis

Objective: To examine the performance of the Norwegian version of the AUSCAN Index as a disease-specific health status measure in patients with hand osteoarthritis (OA). Methods: One hundred and ninety-nine patients with clinical hand OA (mean (SD) age 61.7 (5.7) years, 18 (9%) males) underwent a comprehensive examination including joint status, examination of grip strength and completion of several self-reported health status questionnaires. The Australian/Canadian OA hand index (AUSCAN) captures three different dimensions of hand OA: pain (5 items), stiffness (1 item), and difficulties with daily activities (9 items). Our pre-study hypothesis was to identify AUSCAN as a specific hand measure with strong correlations to hand measures and lower correlations to other general measures of health. Results: Patient completion of the AUSCAN Index was similar or better than other measures. The internal consistency of the AUSCAN was excellent. The pain and physical dimension of AUSCAN correlated substantially to, each other and moderately to the stiffness scale. The AUSCAN physical scale correlated moderately to substantially to other measures, the highest correlation being seen with the Arthritis Impact Measurement Scale (AIMS) 2 hand and finger function scale (r= 0.73). The standardised differences between patients with and without radiographic abnormalities were numerically larger for the AUSCAN pain and physical scales than for other measures. Conclusion: The Norwegian version of the AUSCAN has an acceptable clinimetric performance and is a suitable tool for assessment of hand OA. (C) 2005 OsteoArthritis Research Society International.

Three-dimensional simulation of the rolling of a saturated fibro-porous media

This paper describes recent advances made in computational modelling of the sugar cane liquid extraction process. The saturated fibro-porous material is rolled between circumferentially grooved rolls, which enhance frictional grip and provide a low-resistance path for liquid flow during the extraction process. Previously reported two-dimensional (2D) computational models, account for the large deformation of the porous material by solving the fully coupled governing fibre stress and fluid-flow equations using finite element techniques. While the 2D simulations provide much insight into the overarching cause-effect relationships, predictions of mechanical quantities such as roll separating force and particularly torque as a function of roll speed and degree of compression are not satisfactory for industrial use. It is considered that the unsatisfactory response in roll torque prediction may be due to the stress levels that exist between the groove tips and roots which have been largely neglected in the geometrically simplified 2D model. This paper gives results for both two- and three-dimensional finite element models and highlights their strengths and weaknesses in predicting key milling parameters. (c) 2005 Elsevier B.V.
