Pulse phase-coherent timing and spectroscopy of CXOU J164710.2−45521 outbursts

We present a long-term phase-coherent timing analysis and pulse-phase resolved spectroscopy for the two outbursts observed from the transient anomalous X-ray pulsar CXOU J164710.2−455216. For the first outburst we used 11 Chandra and XMM–Newton observations between 2006 September and 2009 August, the longest baseline yet for this source. We obtain a coherent timing solution with P = 10.61065583(4) s, Ṗ = 9.72(1) × 10−13 s s−1 and P̈ = –1.05(5) × 10−20 s s−2. Under the standard assumptions this implies a surface dipolar magnetic field of ∼1014 G, confirming this source as a standard B magnetar. We also study the evolution of the pulse profile (shape, intensity and pulsed fraction) as a function of time and energy. Using the phase-coherent timing solution we perform a phase-resolved spectroscopy analysis, following the spectral evolution of pulse-phase features, which hints at the physical processes taking place on the star. The results are discussed from the perspective of magnetothermal evolution models and the untwisting magnetosphere model. Finally, we present similar analysis for the second, less intense, 2011 outburst. For the timing analysis we used Swift data together with 2 XMM–Newton and Chandra pointings. The results inferred for both outbursts are compared and briefly discussed in a more general framework.

Direct Visual Servoing Framework based on Optimal Control for Redundant Joint Structures

This paper presents a new framework based on optimal control to define new dynamic visual controllers to carry out the guidance of any serial link structure. The proposed general method employs optimal control to obtain the desired behaviour in the joint space based on an indicated cost function which determines how the control effort is distributed over the joints. The proposed approach allows the development of new direct visual controllers for any mechanical joint system with redundancy. Finally, authors show experimental results and verifications on a real robotic system for some derived controllers obtained from the control framework.

A semantic framework for textual data enrichment

In this work we present a semantic framework suitable of being used as support tool for recommender systems. Our purpose is to use the semantic information provided by a set of integrated resources to enrich texts by conducting different NLP tasks: WSD, domain classification, semantic similarities and sentiment analysis. After obtaining the textual semantic enrichment we would be able to recommend similar content or even to rate texts according to different dimensions. First of all, we describe the main characteristics of the semantic integrated resources with an exhaustive evaluation. Next, we demonstrate the usefulness of our resource in different NLP tasks and campaigns. Moreover, we present a combination of different NLP approaches that provide enough knowledge for being used as support tool for recommender systems. Finally, we illustrate a case of study with information related to movies and TV series to demonstrate that our framework works properly.

Contribution to Real-Time Estimation of Crop Phenological States in a Dynamical Framework Based on NDVI Time Series: Data Fusion With SAR and Temperature

In this study, a methodology based in a dynamical framework is proposed to incorporate additional sources of information to normalized difference vegetation index (NDVI) time series of agricultural observations for a phenological state estimation application. The proposed implementation is based on the particle filter (PF) scheme that is able to integrate multiple sources of data. Moreover, the dynamics-led design is able to conduct real-time (online) estimations, i.e., without requiring to wait until the end of the campaign. The evaluation of the algorithm is performed by estimating the phenological states over a set of rice fields in Seville (SW, Spain). A Landsat-5/7 NDVI series of images is complemented with two distinct sources of information: SAR images from the TerraSAR-X satellite and air temperature information from a ground-based station. An improvement in the overall estimation accuracy is obtained, especially when the time series of NDVI data is incomplete. Evaluations on the sensitivity to different development intervals and on the mitigation of discontinuities of the time series are also addressed in this work, demonstrating the benefits of this data fusion approach based on the dynamic systems.

Engaging Immigrants in Youth Sport Coaching: Part 2. A Qualitative Analysis of the Barriers, Facilitators and Motivators for Involvement

Although research in the area of immigrants and their physical activity patterns has been steadily growing, there is still much to learn. The purpose of this study was to identify the barriers, facilitators and motivators facing recent Canadian immigrants as they relate to involvement in coaching youth sport. The quantitative information presented in the first article of this series served as a framework for conducting semi-structured qualitative interviews with 28 immigrant youth-sport coaches. Results of these interviews support the notion that there are two distinct groups of immigrant coaches - the ‘leisure-oriented coach’ (those without coaching occupational aspirations) and the ‘career-oriented coach’ (those with coaching occupational pursuits). Despite sharing several of the same barriers, facilitators and motivators, each group showed marked divergence from the other on a number of aspects in each of these three categories.

Obama 2: future implications for EU-US relations. Jean Monnet/Robert Schuman Paper Series Vol. 12, No. 8, November 2012

Introduction. The week following his reelection, President Obama traveled to Asia – Thailand, Myanmar, and Cambodia –, while facing at home a fiscal cliff, the need to select the next Secretaries of State, Defense, and Treasury, and the resignation of one of America’s most senior and respected generals and Director of the CIA, David Petraeus; all this at the moment wherein the Middle East is burning in flames due to another round of violence between Israel and Hamas. On the other side of the pond, the EU is currently trying to solve or at least contain several crises: the Eurozone, agreeing on the Multiannual Financial Framework 2014-2020, or MFF 2014-2020,2 and saving France.3 For both giants, the American and European priorities are domestic; they both need to do some ‘nation-building at home.’4 The threat of the fiscal cliff in the US and the one of the Eurocrisis in Europe are too important to be ignored and so visceral that they will affect the way both actors behave internationally and interact with one another. The big question since Obama’s reelection has been what will the EU-US relations look like under his second mandate? And will there be any differences from the first one?5 This paper argues that the US-EU relations will remain quite similar as it was under the first Obama presidency. Nevertheless, with the current shift to Asia, the ‘pivot,’ the EU will be required to increase its contributions to global politics and international security. This paper is structured in three parts. First, the economic and political climax of the EU and the US will be presented. In a second a part, the EU and US strategies and foreign policies will be laid out. Last but not least, several core issues facing the Euro-Atlantic community, such as the Asia pivot, Iran, climate change, and the economy will be addressed. Other issues such as Syria, Afghanistan, and the Middle East and North Africa will not be addressed in this paper.6

What Does the Lisbon Treaty Change Regarding Subsidiarity within the EU Institutional Framework?

he principle of subsidiarity refers in general to the choice of the most suitable and efficient level for taking policy action. The European Union associates subsidiarity with the way of taking decisions ‘as closely as possible to the citizen’, as it is referred to in the EU treaties. Thus, ensuring the respect of subsidiarity within the EU legislative framework ensures that any EU action is justified when proposing draft legislative acts. The Lisbon Treaty establishes new mechanisms reinforcing subsidiarity control, both ex ante and ex post the EU legislative process, and by doing so, enhances mainly the role of the national parliaments (and to a lesser extent the regional parliaments) and the Committee of the Regions. But in the end, this is a way of ensuring legitimacy of the EU action as it is quite often questioned, especially in times of crisis. Years of practice will tell whether the words will join reality.

Casual but Smart: The Court’s new clothes in the Area of Freedom Security and Justice (AFSJ) after the Lisbon Treaty. Research Papers in Law, 2/2008

Introduction. Unintended as it was, the European Court of Justice (ECJ, the Court, the Court of the EU) has played an extremely important role in the construction of the Area of Freedom Security and Justice (AFSJ). The AFSJ was set up by the Treaty of Amsterdam in 1997 and only entered into force in May 1999. The fact that this is a new field of EU competence, poses 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) extent of the protection given to fundamental rights. The above questions have prompted judicial solutions which 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.1 The ECJ is the body whose institutional role is to benefit most from this upcoming ‘depilarisation’, possibly more than that of the European Parliament. This structure is on the verge of being abandoned, provided the Treaty of Lisbon enters into force.2 However spectacular this formal boost of the Court’s competence, the changes in real terms are not going to be that dramatic. This apparent contradiction is explained, to a large extent, by the fact that the Court has in many ways ‘provoked’, or even ‘anticipated’, the depilarisation of its own jurisdictional role, already under the existing three-pillar structure. Simply put, under the new – post Treaty of Lisbon – regime, the Court will have full jurisdiction over all AFSJ matters, as those are going to be fully integrated in what is now the first pillar. Some limitations will continue to apply, however, while a special AFSJ procedure will be institutionalised. Indeed, if we look into the new Treaty we may identify general modifications to the Court’s structure and jurisdiction affecting the AFSJ (section 2), modifications in the field of the AFSJ stemming from the abolition of the pillar structure (section 3) and, finally, some rules specifically applicable to the AFSJ (section 4).

The ENP in the light of the new “neighbourhood clause” (Article 8 TEU). Research Papers in Law, 2/2011

This short contribution outlines the renewed constitutional framework in which the “European Neighbourhood Policy” (ENP) is to be integrated and further developed (1.) and briefly discusses its possible implications for the finalité of the neighbourhood relationship in general and of the ENP more specifically (2.). This constitutional perspective reveals three – already well-known – conceptual problems of the ENP (3.).

Morocco at the Crossroads: Seizing the window of opportunity for sustainable development. MEDPRO Technical Report No. 2/April 2011

The question of state sustainability is highly relevant in the case of Morocco. Despite the image of a modernising and liberalising country, Morocco is undergoing a delicate phase in its development. The recent upheavals in the Maghreb and the Middle East alongside the growing problems of poor education and high unemployment are likely to bring to the surface the unsustainable elements of Morocco’s status quo. The central issues concern the quality of institutions, reforms aimed at promoting the rule of law, curbing corruption and overhauling the judiciary. This paper will argue that while institutional quality is a pre-requisite for successful and sustainable socioeconomic performance, this cannot be achieved unless major reforms in the political system are carried out. There exists a window of opportunity to accelerate reforms and to address the acute centralisation of Moroccan politics and decision-making, the lack of accountability of the monarchic institutions, as well as the fragility of representative bodies, such as parties and trade unions. Seizing this window of opportunity could spare Morocco a period of instability, while also assuring continuity in the framework of the transition that started in 1999 when the new king came to power.

Population Scenarios for South Mediterranean Countries 2010-2050. MEDPRO Report No. 2, August 2012

The European Neighbourhood Policy (ENP) and its follow-up, the Union for the Mediterranean (UfM), were created in 2004 and 2008 to strengthen the prosperity, stability and security of all countries and avoid the emergence of new dividing lines between the EU and 16 neighbouring countries, including south Mediterranean countries (SMCs). Demographic factors in both EU and neighbouring countries will influence this goal. This report describes four population growth scenarios for SMCs, obtained using the MEDPRO economic-political development framework on how indicators of fertility, mortality and international migration might change if people in SMCs were to live in different macroeconomic and political contexts. Qualitative scenarios were then operationalized leading to four different quantitative scenarios using assumptions about possible trends in indicators of fertility, mortality and international migration. The paper concludes by reflecting on the results in light of recent political developments in the region.

Preventing another Euro Area Crisis: EU Economic Governance ‘Six Pack’ – a case of too little, too late? Paper from the Colloquium: The Politics and Economics of the Euro Crisis, Institute for European Studies, University of Malta, 2 December 2011

Summary: The ‘Six Pack’ forms part of the economic governance reforms which are being implemented in order to prevent a repeat of the current sovereign debt crisis in the Euro Area. This legislative package involves strengthening the Stability and Growth Pact, with stronger financial sanctions and more focus on debt; a new directive on national budgetary frameworks and a new framework to monitor and correct macroeconomic imbalances. Furthermore, the implementation of the ‘Six Pack’ also involves procedural reforms, in particular reverse majority voting, as well as more oversight by the European Parliament. Inter-institutional negotiations on the ‘Six Pack’ took over a year. In the meantime, the sovereign debt crisis had deepened and broadened, implying that the ‘Six Pack’ may have come ‘too late’. The ‘Six Pack’ has also proved to be ‘too little’ to address the crisis and by the time it entered into force, further measures and proposals to strengthen economic governance had to be made. Nevertheless, the ‘Six Pack’ comprises some positive developments. In particular, recognising that fiscal policy is a matter of national sovereignty, it sets a new approach which relies on institutional reforms at national level. As such, it constitutes a first, small step to improve economic governance in the Euro Area.

Identity Construction in Europe: A Discursive Approach. IES WORKING PAPER 2/2010

Proposing a discursive approach to studying identity, this paper presents Positioning Theory as a theoretical framework for conceptualizing the construction of identity in discourse. The Positioning Diamond is employed to analyse the discourse surrounding the Danish Euro referendum. The analysis reveals how identities are constructed in discourse that promotes a ‘yes’ or ‘no’ vote in the referendum, highlighting the generally implicit allocation of rights and duties to actors within a specific narrative context. The penultimate section discusses appropriate criteria for evaluating discursive accounts, distinguishing between cases in which truth, normative and ethical criteria are applicable. Finally, the paper concludes with a discussion of policy considerations and recommendations.

Coalitions, Power and Institutional Change in Global Patent Politics. IES WORKING PAPER 2/2013

With the 1995 Agreement on Trade - related Aspects of Intellectual Property Rights (TRIPS), a centralised rule - system for the international governance of patents was put in place under the general framework of the World Trade Organisation (WTO). Since then, the number of patent – related institutions has increased monotonically on the multilateral, plurilateral and bilateral levels. I will explain this case of institutional change by focusing on the norm – setting activities of both industrialised and developing countries, arguing that both groups constitute internally highly cohesive coalitions in global patent politics, while institutional change occurs when both coalitions engage in those negotiating settings in which they enjoy a comparative advantage over the other coalition. Specifically, I make the point that industrialised countries’ norm – setting activities take place on the plurilateral and bilateral level, where economic factors can be effectively translated into political outcomes while simultaneously avoiding unacceptably high legitimacy costs; whereas developing countries, on the other hand, use various multilateral United Nations (UN) forums where their claims possess a high degree of legitimacy, but cannot translate into effective political outcomes. The paper concludes with some remarks on how this case yields new insights into ongoing debates in institutionalist International Relations (IR), as pertaining to present discussions on “regime complexity”.
