Static versus dynamic heterogeneities in the D=3 Edwards-Anderson-ising spin glass

We numerically study the aging properties of the dynamical heterogeneities in the Ising spin glass. We find that a phase transition takes place during the aging process. Statics-dynamics correspondence implies that systems of finite size in equilibrium have static heterogeneities that obey finite-size scaling, thus signaling an analogous phase transition in the thermodynamical limit. We compute the critical exponents and the transition point in the equilibrium setting, and use them to show that aging in dynamic heterogeneities can be described by a finite-time scaling ansatz, with potential implications for experimental work.

Brazil and the EU in the global economy. CEPS Working Document No. 371, February 2013

The structure of the world economy has been changing quickly during the last decade. The emerging global economy is much more fragmented than in the past and characterised by different global actors, each one with specific features and roles. In this setting, both Brazil and the European Union play role. This paper, without pretending to provide a full analysis of the European and Brazilian economies, offers a description of their main international economic features to understand their current and future role in the global order.

The adoption of IPSASs in the Iberian Peninsula: the perspective of the standar-setters

The last decades have been fruitful in reforms in public sector accounting across the world, namely moving from cash-based into accrual-based regimes. In this process of bringing public sector accounting close to business accounting, International Public Sector Accounting Standards (IPSASs) have been developed and adopted in several countries. In the EU context, public sector harmonization among member-States is currently being considered, namely via the development of European Public Sector Accounting Standards (EPSASs). Both IPSASs and EPSASs are understood as, among other things, important to contribute for a more informative and transparent financial reporting of public sector entities and governments. Moreover they are expected to approximate public sector accounting and the National Accounts, hence allowing for more reliable information to monitor fiscal discipline among EU countries. The Iberian countries, after using accrual accounting in the public sector for more than twenty years (Spain from middle 1980s and Portugal from 1990s), have acknowledged the need to embark in an international harmonization process adopting IPSASs, particularly after the adoption of IFRSs in the business sector, which was creating some difficulties for consolidated accounts. Spain has passed the Chart of Accounts for the Public Sector through the Order EHA/1037/2010, which is adapted to IPSASs; Portugal has just passed Law-decree 192/2015, September 11, and is expecting to start implementation in 2017. In both countries a central role in this reform has been assumed by the national standard-setters for public sector accounting. Based on the “Actor Network Theory” to help understanding how and why organizations interact and how this interaction could have an impact on their choice of accounting policies, this paper aims to analyse, from the Iberian public sector accounting standard-setters perspective, how the adoption/adaptation of IPSASs has been considered and developed in these countries. Research questions to be considered are the following, which will be asked in interviews to the members of the standard-setting committees in both Portugal and Spain: • What were the driving forces leading to the decision to adopt and implement IPSASs? • Which other governmental bodies’ experiences, if any, were considered in the adoption of IPSASs? • What specific steps were/are being undertaken to prepare for the conversion from the existing system to IPSASs? • What were/are the institutional challenges faced/expected to face? • What assistance have been received from IFAC and/or IPSASB, or from other sources, if any, throughout the adoption/implementation? • How can the success of the adoption/implementation be characterised? • What benefits can/have the government derive/derived from the adoption and implementation of IPSASs? The paper is expected to contribute to the understanding of the issues underlying the process of embarking in public sector accounting reforms towards IPSASs.

The ‘Lisbonisation’ of the European Parliament: Assessing progress, shortcomings and challenges for democratic accountability in the area of freedom, security and justice. CEPS Paper on Liberty and Security in Europe No. 58, September 2013

This paper examines the performance of the European Parliament in EU AFSJ law and policy-making from the entry into force of the Lisbon Treaty until the end of the first half of 2013. The paper situates the EP in the new post-Lisbon institutional setting, documenting its transition to ‘AFSJ decision-maker’, and its new powers to shape and make policy covering the EU’s internal and external security agenda. While the paper finds that the EP has become an active co-owner of the EU AFSJ post-Lisbon, with the Parliament demonstrating a dynamic adjustment to its new post-Lisbon role and powers, the authors identify a set of new developments and challenges that have arisen in the conduct of democratic accountability by the EP in the AFSJ since 2009, which call for critical reflection ahead of the new parliamentary term 2014-2019 and the post-2014 phase of the EU’s AFSJ.

With or without you...judging politically in the field of Area of Freedom, Security and Justice? Research Papers in Law, 3/2007

From the Introduction. The study of the European Court of Justice’s (ECJ) case law of the regarding the Area of Freedom Security and Justice (AFSJ) is fascinating in many ways.1 First, almost the totality of the relevant case law is extremely recent, thereby marking the first ‘foundational’ steps in this field of law. This is the result of the fact that the AFSJ was set up by the Treaty of Amsterdam in 1997 and only entered into force in May 1999.2 Second, as the AFSJ is a new field of EU competence, it sets afresh all the fundamental questions – both political and legal – triggered by European integration, namely in terms of: a) distribution of powers between the Union and its member states, b) attribution of competences between the various EU Institutions, c) direct effect and supremacy of EU rules, d) scope of competence of the ECJ, and e) measure of the protection given to fundamental rights. The above questions beg for answers which should take into account both the extremely sensible fields of law upon which the AFSJ is anchored, and the EU’s highly inconvenient three-pillar institutional framework.3 Third, and as a consequence of the above, the vast majority of the ECJ’s judgments relating to the AFSJ are a) delivered by the Full Court or, at least, the Grand Chamber, b) with the intervention of great many member states and c) often obscure in content. This is due to the fact that the Court is called upon to set the foundational rules in a new field of EU law, often trying to accommodate divergent considerations, not all of which are strictly legal.4 Fourth, the case law of the Court relating to the AFSJ, touches upon a vast variety of topics which are not necessarily related to one another. This is why it is essential to limit the scope of this study. The content of, and steering for, the AFSJ were given by the Tampere European Council, in October 1999. According to the Tampere Conclusions, the AFSJ should consist of four key elements: a) a common immigration and asylum policy, b) judicial cooperation in both civil and penal matters, c) action against criminality and d) external action of the EU in all the above fields. Moreover, the AFSJ is to a large extent based on the Schengen acquis. The latter has been ‘communautarised’5 by the Treaty of Amsterdam and further ‘ventilated’ between the first and third pillars by decisions 1999/435 and 1999/436.6 Judicial cooperation in civil matters, mainly by means of international conventions (such as the Rome Convention of 1981 on the law applicable to contractual obligations) and regulations (such as (EC) 44/20017 and (EC) 1348/20008) also form part of the AFSJ. However, the relevant case law of the ECJ will not be examined in the present contribution.9 Similarly, the judgments of the Court delivered in the course of Article 226 EC proceedings against member states, will be omitted.10 Even after setting aside the above case law and notwithstanding the fact that the AFSJ only dates as far back as May 1999, the judgments of the ECJ are numerous. A simple (if not simplistic) categorisation may be between, on the one hand, judgments which concern the institutional setting of the AFSJ (para. 2) and, on the other, judgments which are related to some substantive AFSJ policy (para. 3).

Fundamental Rights of workers in the Digital Age: A methodological approach from a case study. WP C.S.D.L.E. "Massimo D'Antona" .INT - 89/2011

The relationship between employer and worker is not only obligatory but above all, as Sinzheimer said, a ‘relationship of power’. In the Digital Age this statement is confirmed by the massive introduction of ICT in most of the companies that increase, in practice, employer’s supervisory powers. This is a worrying issue for two reasons: on one hand, ICT emerge as a new way to weaken the effectiveness of fundamental rights and the right to dignity of workers; and, on the other hand, Spanish legal system does not offer appropriate solutions to ensure that efficacy. Moreover, in a scenario characterized by a hybridization of legal systems models –in which traditional hard law methods are combined with soft law and self regulation instruments–, the role of our case law has become very important in this issue. Nevertheless, despite the increase of judicialization undergone, solutions offered by Courts are so different that do not give enough legal certainty. Facing this situation, I suggest a methodological approach –using Alchourron and Bulygin’s normative systems theory and Alexy’s fundamental rights theory– which can open new spaces of decision to legal operators in order to solve properly these problems. This proposal can allow setting a policy that guarantees fundamental rights of workers, deepening their human freedom in companies from the Esping-Andersen’s de-commodification perspective. With this purpose, I examine electronic communications in the company as a case study.

Bulgarian-Russian games in the energy sector: an outcome is getting closer. OSW Commentary No. 61, 2011-10-5

Bulgaria and Russia are entering the final phase of setting the conditions of their co-operation in the energy sector. A new gas contract is being negotiated because the currently applicable agreements will have expired by the end of 2012. The fate of two major energy projects – whose implementation depends on good co-operation between Sofia and Moscow: the Burgas– –Alexandroupolis oil pipeline and the construction of a Bulgarian nuclear power plant in Belene with Russian participation – is currently being decided. Another issue ever-present on the agenda is the future of the South Stream gas pipeline promoted by Russia, which is to run through Bulgarian territory. The outcome of all the aforementioned discussions and negotiations will determine for years the model of Bulgarian-Russian relations and may strongly affect the shape of the oil, gas and electricity markets in South-Eastern Europe.

Changes in the political elite, economy and society of Belarus: Appearances and reality. OSW Study 30/2008

In late 2006 and early 2007, relations between Russia and Belarus were hit by the most serious crisis in many years. In a setting of heightened tension, the Belarusian authorities decided to gradually modify their economic policy and thoroughly restructure the ruling class. The new situation created new, much more difficult challenges for the Belarusian opposition. The processes initiated by the authorities were not intended to bring about either the democratisation of public and political life or full economic liberalisation; their only purpose was to enable the regime to tackle new challenges and survive in the changing international context. Nevertheless, modernisation has been initiated in Belarus' authoritarian system of power, which until now was considered to be completely incapable of reform. This puts the country's main political and economic partners, including the European Union, in a new situation.

EU Migration Policy in the wake of the Arab Spring. What prospects for EU-Southern Mediterranean Relations? MEDPRO Technical Report No. 15/August 2012

The outbreak of the Arab Spring and the unrest, revolution and war that followed during the course of 2011 have forced the EU to acknowledge the need to radically re-think its policy approach towards the Southern Mediterranean, including in the domain of migration. Migration and mobility now feature as key components of High Representative Catherine Ashton’s new framework for cooperation with the region (Partnership for Democracy and Shared Prosperity), while the EU has declared its intention to strengthen its external migration policy by setting up “mutually beneficial” partnerships with third countries – so-called ‘Dialogues for Migration, Mobility and Security’ – now placed at the centre of the EU’s renewed Global Approach to Migration and Mobility (GAMM). However, the success of this approach and its potential to establish genuine cooperative partnerships that will support smooth economic and political transformation in North Africa hinge on the working arrangements and institutional configurations shaping the renewed GAMM at EU level which has long been marked by internal fragmentation, a lack of transparency and a predominance of home affairs and security actors. This paper investigates the development of the Dialogues for Migration, Mobility and Security with the Southern Mediterranean in a post-Lisbon Treaty institutional setting. It asks to what extent has the application of the Lisbon Treaty and the creation of an “EU Foreign Minister” in High Representative Ashton, supported by a European External Action Service (EEAS), remedied or re-invigorated the ideological and institutional struggles around the implementation of the Global Approach? Who are the principal agents shaping and driving the Dialogues for Migration, Mobility and Security? Who goes abroad to speak on the behalf of the EU in these Dialogues and what impact does this have on the effectiveness, legitimacy and accountability of the Dialogues under the renewed GAMM as well as the wider prospects for the Southern Mediterranean?

The Relevance of International Spillovers and Asymmetric Effects in the Taylor Rule. CEPS Working Document No. 403, February 2015

Deviations of policy interest rates from the levels implied by the Taylor rule have been persistent before the financial crisis and increased especially after the turn of the century. Compared to the Taylor benchmark, policy rates were often too low. This paper provides evidence that both international spillovers, for instance international dependencies in the interest rate-setting of central banks, and nonlinear reaction patterns can offer a more realistic specification of the Taylor rule in the main industrial countries. The inclusion of international spillovers and, even more, nonlinear dynamics improves the explanatory power of standard Taylor reaction functions. Deviations from Taylor rates tend to be smaller and their negative trend can be eliminated.

Taiwanese Lobbying in the European Union: ‘Workable Diplomacy’ and its Limitations. EU Diplomacy Paper 8/2015

The policy of the European Union (EU) towards Taiwan has mostly been analysed either as a by-product of EU-China relations or with reference to the general lack of a European geopolitical approach towards East Asia. By adopting a lobbying approach which focusses on Taiwan’s different ‘channels of influence’ within the complex European foreign policy system in Brussels, this study provides new insights into the functioning of EU-Taiwan relations. It also sheds new light on the implications of the radical change in Taiwanese diplomacy after 2008, when Chen Shui-bian’s assertive and identity-based diplomacy was replaced with the Kuomintang’s new dogma of ‘workable diplomacy’. Based on semi-guided interviews with Taiwanese and European actors, this paper examines why Taiwanese lobbying in Brussels, albeit very active and professional, is not salient enough to meet the challenges arising from the overwhelming Chinese competition and from the increasing proliferation of regional trade agreements – with active EU participation – in the Asia-Pacific region. It argues that the pragmatic ‘workable diplomacy’ approach, while smoothing out working-level relations between Taiwan and the EU, fails to attract a sufficient degree of political and public attention in Europe to the Taiwan question and thus fosters the neglect of Taiwan by European foreign policy-makers. The main challenge faced by Taiwanese diplomacy, however, is not simply one of convincing through technical arguments, but one of agenda setting, that is, of redefining European priorities in Taiwan’s favour.

System Costs of Variable Renewable Energy in the European Union. Bruges European Economic Policy (BEEP) Briefings 37/2015

To shift to a low-carbon economy, the EU has been encouraging the deployment of variable renewable energy sources (VRE). However, VRE lack of competitiveness and their technical specificities have substantially raised the cost of the transition. Economic evaluations show that VRE life-cycle costs of electricity generation are still today higher than those of conventional thermal power plants. Member States have consequently adopted dedicated policies to support them. In addition, Ueckerdt et al. (2013) show that when integrated to the power system, VRE induce supplementary not-accounted-for costs. This paper first exposes the rationale of EU renewables goals, the EU targets and current deployment. It then explains why the LCOE metric is not appropriate to compute VRE costs by describing integration costs, their magnitude and their implications. Finally, it analyses the consequences for the power system and policy options. The paper shows that the EU has greatly underestimated VRE direct and indirect costs and that policymakers have failed to take into account the burden caused by renewable energy and the return of State support policies. Indeed, induced market distortions have been shattering the whole power system and have undermined competition in the Internal Energy Market. EU policymakers can nonetheless take full account of this negative trend and reverse it by relying on competition rules, setting-up a framework to collect robust EU-wide data, redesigning the architecture of the electricity system and relying on EU regulators.

Age determination and paleotemperatures of sediment cores TTR17-1_384B and TTR17-1_436B in the Alboran Sea

Climate conditions in the westernmost Mediterranean (Alboran Sea basin) over the last two millennia have been reconstructed through integration of molecular proxies applied for the first time in this region at such high resolution. Two temperature proxies, one based on isoprenoid membrane lipids of marine Thaumarchaeota (TEXH86-tetraether index of compounds consisting of 86 carbons) and the other on alkenones produced by haptophytes (UK'37 ratio) were applied to reconstruct sea surface temperature (SST). Both records reveal a progressive long term decline in SST over the last two millennia and an increased rate of warming during the second half of the twentieth century. This is in accord with previous temperature reconstructions for the Northern Hemisphere. TEXH86 temperature values are higher than those inferred from UK'37, probably due to differences in the bloom season of haptophytes and Thaumarchaeota, and reflect summer SST. The branched vs. isoprenoid tetraether index (BIT index) suggests a low contribution of soil organic matter (OM) to the sedimentary OM. The stable carbon isotopic composition of long chain n-alkanes indicates a predominant C3 plant contribution, with no major change in vegetation over the last 2000 yr. The distribution of long chain 1,14-diols (most likely sourced by Proboscia species in this setting) provided insight into variation in upwelling conditions during the last 2000 yr and depicts a correlation with the North Atlantic Oscillation (NAO) index, providing evidence of enhanced wind induced upwelling during periods of a persistent positive mode of the NAO.

'Institutional Shopping' for Natural Resource Management in a Protected Area and Indigenous Territory in the Bolivian Amazon.

Focusing on an overlapping protected area and indigenous territory in the Bolivian Amazon, this article discusses how indigenous people continue to negotiate access to natural resources. Using the theoretical framework of New Institutionalism, ethnographic data from participatory observations, and interviews with Takana indigenous resource users and park management staff, we identified four phases of institutional change. We argue that under the current institutionally pluralistic setting in the overlapping area, indigenous users apply “institutional shopping” to choose, according to their power and knowledge, the most advantageous institutional framework in a situation. Indigenous users strategically employed arguments of conservation, indigeneity, or long-term occupation to legitimize their claims based on the chosen institution. Our results highlight the importance of ideologies and bargaining power in shaping the interaction of individuals and institutions. As a potential application of our research to practice, we suggest that rather than seeing institutional pluralism solely as a threat to successful resource management, the strengths of different frameworks may be combined to build robust institutions from the bottom up that are adapted to the local context. This requires taking into account local informal institutions, such as cultural values and beliefs, and integrating them with conservation priorities through cross-cultural participatory planning.
