UBER: Innovation or déja vu? CEPS Commentary, 25 February 2015

The emergence of the controversial car service Uber has provoked a wide and heated discussion among economists specialising in the services sector in recent months. This Commentary explores the most salient questions being raised in the debate: Does Uber really offer a new service? And does it represent true innovation? The authors argue that there are some very interesting innovative elements associated with Uber, but those related to the specific industrial relations model might prove to be prejudiced against drivers.

The EU regime on biofuels in transport: Still in search of sustainability. Egmont Paper No. 68, July 2014

Like other regions of the world, the EU is developing biofuels in the transport sector to reduce oil consumption and mitigate climate change. To promote them, it has adopted favourable legislation since the 2000s. In 2009 it even decided to oblige each Member State to ensure that by 2020 the share of energy coming from renewable sources reached at least 10% of their final consumption of energy in the transport sector. Biofuels are considered the main instrument to reach that percentage since the development of other alternatives (such as hydrogen and electricity) will take much longer than expected. Meanwhile, these various legislative initiatives have driven the production and consumption of biofuels in the EU. Biofuels accounted for 4.7% of EU transport fuel consumption in 2011. They have also led to trade and investment in biofuels on a global scale. This large-scale expansion of biofuels has, however, revealed numerous negative impacts. These stem from the fact that first-generation biofuels (i.e., those produced from food crops), of which the most important types are biodiesel and bioethanol, are used almost exclusively to meet the EU’s renewable 10% target in transport. Their negative impacts are: socioeconomic (food price rises), legal (land-grabbing), environmental (for instance, water stress and water pollution; soil erosion; reduction of biodiversity), climatic (direct and indirect land-use effects resulting in more greenhouse gas emissions) and public finance issues (subsidies and tax relief). The extent of such negative impacts depends on how biofuel feedstocks are produced and processed, the scale of production, and in particular, how they influence direct land use change (DLUC) and indirect land use change (ILUC) and the international trade. These negative impacts have thus provoked mounting debates in recent years, with a particular focus on ILUC. They have forced the EU to re-examine how it deals with biofuels and submit amendments to update its legislation. So far, the EU legislation foresees that only sustainable biofuels (produced in the EU or imported) can be used to meet the 10% target and receive public support; and to that end, mandatory sustainability criteria have been defined. Yet they have a huge flaw. Their measurement of greenhouse gas savings from biofuels does not take into account greenhouse gas emissions resulting from ILUC, which represent a major problem. The Energy Council of June 2014 agreed to set a limit on the extent to which firstgeneration biofuels can count towards the 10% target. But this limit appears to be less stringent than the ones made previously by the European Commission and the European Parliament. It also agreed to introduce incentives for the use of advanced (second- and third-generation) biofuels which would be allowed to count double towards the 10% target. But this again appears extremely modest by comparison with what was previously proposed. Finally, the approach chosen to take into account the greenhouse gas emissions due to ILUC appears more than cautious. The Energy Council agreed that the European Commission will carry out a reporting of ILUC emissions by using provisional estimated factors. A review clause will permit the later adjustment of these ILUC factors. With such legislative orientations made by the Energy Council, one cannot consider yet that there is a major shift in the EU biofuels policy. Bolder changes would have probably meant risking the collapse of the high-emission conventional biodiesel industry which currently makes up the majority of Europe’s biofuel production. The interests of EU farmers would have also been affected. There is nevertheless a tension between these legislative orientations and the new Commission’s proposals beyond 2020. In any case, many uncertainties remain on this issue. As long as solutions have not been found to minimize the important collateral damages provoked by the first generation biofuels, more scientific studies and caution are needed. Meanwhile, it would be wise to improve alternative paths towards a sustainable transport sector, i.e., stringent emission and energy standards for all vehicles, better public transport systems, automobiles that run on renewable energy other than biofuels, or other alternatives beyond the present imagination.

The nuclear safety framework in the European Union after Fukushima. Egmont Paper No. 73, December 2014

Summary. On 11 March 2011, a devastating earthquake struck Japan and caused a major nuclear accident at the Fukushima Daiichi nuclear plant. The disaster confirmed that nuclear reactors must be protected even against accidents that have been assessed as highly unlikely. It also revealed a well-known catalogue of problems: faulty design, insufficient back-up systems, human error, inadequate contingency plans, and poor communications. The catastrophe triggered the rapid launch of a major re-examination of nuclear reactor security in Europe. It also stopped in its tracks what had appeared to be a ‘nuclear renaissance’, both in Europe and globally, especially in the emerging countries. Under the accumulated pressure of rising demand and climate warming, many new nuclear projects had been proposed. Since 2011 there has been more ambivalence, especially in Europe. Some Member States have even decided to abandon the nuclear sector altogether. This Egmont Paper aims to examine the reactions of the EU regarding nuclear safety since 2011. Firstly, a general description of the nuclear sector in Europe is provided. The nuclear production of electricity currently employs around 500,000 people, including those working in the supply chain. It generates approximately €70 billion per year. It provides roughly 30% of the electricity consumed in the EU. At the end of 2013, there were 131 nuclear power reactors active in the EU, located in 14 countries. Four new reactors are under construction in France, Slovakia and Finland. Secondly, this paper will present the Euratom legal framework regarding nuclear safety. The European Atomic Energy Community (EAEC or Euratom) Treaty was signed in 1957, and somewhat obscured by the European Economic Community (EEC) Treaty. It was a more classical treaty, establishing institutions with limited powers. Its development remained relatively modest until the Chernobyl catastrophe, which provoked many initiatives. The most important was the final adoption of the Nuclear Safety Directive 2009/71. Thirdly, the general symbiosis between Euratom and the International Atomic Energy Agency (IAEA) will be explained. Fourthly, the paper analyses the initiatives taken by the EU in the wake of the Fukushima catastrophe. These initiatives are centred around the famous ‘stress tests’. Fifthly, the most important legal change brought about by this event was the revision of Directive 2009/71. Directive 2014/87 has been adopted quite rapidly, and has deepened in various ways the role of the EU in nuclear safety. It has reinforced the role and effective independence of the national regulatory authorities. It has enhanced transparency on nuclear safety matters. It has strengthened principles, and introduced new general nuclear safety objectives and requirements, addressing specific technical issues across the entire life cycle of nuclear installations, and in particular, nuclear power plants. It has extended monitoring and the exchange of experiences by establishing a European system of peer reviews. Finally, it has established a mechanism for developing EU-wide harmonized nuclear safety guidelines. In spite of these various improvements, Directive 2014/87 Euratom still reflects the ambiguity of the Euratom system in general, and especially in the field of nuclear safety. The use of nuclear energy remains controversial among Member States. Some of them remain adamantly in favour, others against or ambivalent. The intervention of the EAEC institutions remains sensitive. The use of the traditional Community method remains limited. The peer review method remains a very peculiar mechanism that deserves more attention.

The History and Challenges of Cohesion Policies. Jean Monnet/Robert Schuman Paper Series Vol. 14 No. 2, February 2014

From Introduction. Regional economic disequilibria was viewed as both an obstacle to and result of integration (European Commission 1965; European Commission 1962; European Commission 1969). Even within the Treaty of Rome, the Community tried to establish mechanisms to alleviate regional inequality. However, it was not until 1975 that the main mechanism of regional policy was established as a result of British and Irish enlargement: the European Regional Development Fund (ERDF). Since then, cohesion policy has become a significant EU expenditure accounting for €347bn, or 35.7% of the total EU budget for 2007-13(European Commission Regional Policy-Info Regio 2012). It has also become a key policy linked to enlargement. The underlying principle of cohesion policy assumes that the market alone cannot solve development problems and therefore government intervention is needed. This notion is in direct contrast to the underlying principle of EU competition policy, which asserts that the free market can solve economic development problems (Meadows, interview by author, 2003). The logic underlying cohesion policy is not only counter to EU competition policy, but also regulatory policies. Unlike other EU policies, cohesion policy is not a sectoral policy, but rather territorial in nature (Leonardi, 2006). Thus at times EU regulatory policy has also unintentionally worked counter to the goals of regional policy, sometimes disadvantaging poorer regions (Dudek, 2005). As the Community has sought to ameliorate regional disparities, it meant that all levels of government: local, regional, national and supranational would need to be involved, however, member states have different territorial governance and European regional development programs have to varying degrees impacted the relationship and policy responsibility of different levels of government (Leonardi, 2006; Bachtler and Michie 1993; Marks, 1993). The very nature of regional development policy has provoked a re-examination of subsidiarity, or which level of government is the lowest and most appropriate level. The discussion of policy formulation and implementation at the lowest level possible also addresses the issue of the democratic deficit. Some argue that the closer government is to the people the more responsive and representative it is. Democracy, however, also implies that public funds are used in a transparent way and for public rather than private good. Yet, as we examine the history and current situation of EU regional funds we find that corruption and misuse still abound. Thus, to understand the history of regional policy it is imperative to look at the major transformations of the policy, how regional policy has impacted subsidiarity and the quality of democracy, become an important instrument of enlargement and contradicted or conflicted with other EU policies.

From Lockerbie to Umar Farouk AbdulMutallab (Assessing the Destruction of Civilian Aircrafts by Terrorism). Transatlantic Security Paper N.1–April 2010

Data published by the Federal Aviation Administration (F.A.A.) in its "Annual report on the criminal acts against civil aviation" indicates that in the year 1960, there have been fifteen attacks on board planes leaving 286 dead; 44 in the year 1970 with 650 dead (mostly hijackings); and 26 in the 1980s leaving 1207 dead. In the 1970s, the record is established by the year 1976 (168 dead).The three years - 1985 (390), 1988 (287), and 1989 (278) - were more deadly than the 1960s all together. These casualties were largely provoked by IEDs. Since the end of 1980 - the deadliest decade, with the exception of September 11, 2001 -, it is however a rare practice. The reasons for the decline in big and politically motivated hijackings were varied. One could have been the improvement of the effectiveness of the safety response by States, airports and companies. The improvised explosive device (I.E.D.) posed a serious threat to the civil aviation industry in the 1980s. Since the 1990s, the jihadi networks have regularly tried to target aircrafts using various types of IEDs.

The bumpy road. Difficult reform process in Ukraine. OSW Commentary, Number 192|30.11.2015

The post-Maidan Ukrainian government found itself forced to launch a comprehensive state reform process due to both the deep crisis in all the key areas of the state’s operation and the enormous demand for change among the Ukrainian public. The promise to carry out structural reforms based on the European model became a key point in Kyiv’s political rhetoric. However, one year after the formation of the second cabinet led by Arseniy Yatsenyuk (2 December 2014) and one and a half years since the inauguration of Petro Poroshenko as president (7 June 2014), it is clear that the reform process in Ukraine is moving at a snail’s pace and is far from fulfilling its post-Maidan declarations. It has also provoked increasing frustration among the public due to the lack of expected effects.

A challenge for liberal democracy: How to understand the Russian intervention in Ukraine. Bertelsmann Policy Brief, 16.10.2014

The Russian intervention in Ukraine has provoked a deep crisis which will likely last for years, with profound consequences not only for Ukraine, Russia and Eastern Europe, but also for the internal situation in the European Union. The current Russian aggression is frequently seen as a profound violation of international law, breaking the rules that are fundamental for relations in Europe. It is perceived as perhaps a step towards rebuilding imperial Russia or, at the very least, an attempt to keep Ukraine within Russia’s sphere of influence. However, one very important aspect is virtually neglected, namely, that Russia’s Ukraine venture may have a significant impact on the future of liberal democracy in Europe and beyond.

The EU and the 2016 Terrorist Attacks in Brussels: Better instead of more information sharing. CEPS Commentary, 6 April 2016

The Brussels terrorist attacks of 22 March 2016 provoked widespread political condemnation and public outrage. The events have brought to the fore past discussions regarding the limits of member states’ counterterrorism policies and the extent to which the EU could play a role in shaping more effective responses to these acts of violence.

Efficacy of a Nasal Spray from Citrus limon and Cydonia oblonga for the Treatment of Hay Fever Symptoms - A Randomized, Placebo Controlled Cross-Over Study

Nasal spray from lemon and quince (LQNS) is used to treat hay fever symptoms and has been shown to inhibit histamine release from mast cells in vitro. Forty-three patients with grass pollen allergy (GPA) were randomized to be treated either with placebo or LQNS for one week, respectively, in a cross-over study. At baseline and after the respective treatments patients were provoked with grass pollen allergen. Outcome parameters were nasal flow measured with rhinomanometry (primary), a nasal symptom score, histamine in the nasal mucus and tolerability. In the per protocol population absolute inspiratory nasal flow 10 and 20 min after provocation was higher with LQNS compared to placebo (-37 ± 87 mL/s; p = 0.027 and -44 ± 85 mL/s; p = 0.022). The nasal symptom score showed a trend (3.3 ± 1.8 in the placebo and 2.8 ± 1.5 in the LQNS group; p = 0.070) in favor of LQNS; the histamine concentration was not significantly different between the groups. Tolerability of both, LQNS and placebo, was rated as very good. LQNS seems to have an anti-allergic effect in patients with GPA. Copyright © 2016 John Wiley & Sons, Ltd.

Imperfect Creatures : Vermin, Literature, and the Sciences of Life, 1550-1750 /

Plagues of pests have always been a part of recorded history, but they hold special significance in the early modern period. 'Imperfect Creatures' is the first full-length study to investigate the shifting, unstable, but foundational status of “vermin” as creatures and category in the early modern literary and scientific imagination.

The natural jurisprudence of Jean Barbeyrac: translation as an art of political adjustment

The article makes the case for redescribing Jean Barbeyrac [1674-1744], the great French translator and influential glossator of seventeenth-century Latin natural-law texts, as something quite other than a neutral mediator of Samuel Pufendorf. To consider the specific religious and political charge of his strategies as translator is to recognize the independence of Barbeyrac's Huguenot stance on natura; jurisprudence. This stance is provoked by the profound challenge that Pufendorf's radical post-Wespthalian secularizing of civil authority posed for a Huguenot: how to grant that the state had legitimate authority to regulate all external conduct, but at the same time preserve an inviolable moral space for the exercise of individual conscience. The argument--pointing to Barbeyrac's construction of a 'Lockeanized' Pufendorf--rests both on his famous presentation of Leibniz's critique of Pufendorf's De officio hominis et civis and on more neglected elements of Barbeyrac's corpus.

Price discovery and volatility spillovers in index futures markets: Some evidence from Mexico

This paper investigates the hypotheses that the recently established Mexican stock index futures market effectively serves the price discovery function, and that the introduction of futures trading has provoked volatility in the underlying spot market. We test both hypotheses simultaneously with daily data from Mexico in the context of a modified EGARCH model that also incorporates possible cointegration between the futures and spot markets. The evidence supports both hypotheses, suggesting that the futures market in Mexico is a useful price discovery vehicle, although futures trading has also been a source of instability for the spot market. Several managerial implications are derived and discussed. (C) 2004 Elsevier B.V. All rights reserved.

Lessons from tomographic studies of the mammalian Golgi

Basic structure studies of the biosynthetic machinery of the cell by electron microscopy (EM) have underpinned much of our fundamental knowledge in the areas of molecular cell biology and membrane traffic. Driven by our collective desire to understand how changes in the complex and dynamic structure of this enigmatic organelle relate to its pivotal roles in the cell, the comparatively high-resolution glimpses of the Golgi and other compartments of the secretory pathway offered to us through EM have helped to inspire the development and application of some of our most informative, complimentary (molecular, biochemical and genetic) approaches. Even so, no one has yet even come close to relating the basic molecular mechanisms of transport, through and from the Golgi, to its ultrastructure, to everybody's satisfaction. Over the past decade, EM tomography has afforded new insights into structure -function relationships of the Golgi and provoked a re-evaluation of older paradigms. By providing a set of tools for structurally dissecting cells at high-resolution in three-dimensions (3D), EM tomography has emerged as a method for studying molecular cell biology in situ. As we move rapidly toward the establishment of molecular atlases of organelles through advances in proteomics and genomics, tomographic studies of the Golgi offer the tantalizing possibility that one day, we will be able to map the spatio-temporal coordinates of Golgi-related proteins and lipids accurately in the context of 4D cellular space.

Local therapy for restenosis

The durability of all forms of open or percutaneous revascularisation is affected by the development of localised stenoses within the bypass graft or at the site of endarterectomy, stent or angioplasty. The reported incidence of significant restenosis has varied dependent on initial procedure, site, case mix and definition, but is greatest during the first 12 months (Table 1).1 Over the last 40 years tens of thousands of studies have been carried out in an effort to understand or reduce the incidence of restenosis, with two major mechanisms identified as being responsible for the luminal narrowing, namely intimal hyperplasia and constrictive remodelling. Intimal hyperplasia is provoked by changes in the balance of local cytokines controlling vascular smooth muscle cell (VSMC) proliferation, apoptosis and migration, brought about by endothelial or medial injury and alterations in haemodynamic forces. The overall vessel diameter reduction that occurs in constrictive remodelling is less well defined, but likely involves matrix turnover under the control of proteinases, particularly metalloproteinases.
