New Approaches for Teaching Soil and Rock Mechanics Using Information and Communication Technologies

Soil and rock mechanics are disciplines with a strong conceptual and methodological basis. Initially, when engineering students study these subjects, they have to understand new theoretical phenomena, which are explained through mathematical and/or physical laws (e.g. consolidation process, water flow through a porous media). In addition to the study of these phenomena, students have to learn how to carry out estimations of soil and rock parameters in laboratories according to standard tests. Nowadays, information and communication technologies (ICTs) provide a unique opportunity to improve the learning process of students studying the aforementioned subjects. In this paper, we describe our experience of the incorporation of ICTs into the classical teaching-learning process of soil and rock mechanics and explain in detail how we have successfully developed various initiatives which, in summary, are: (a) implementation of an online social networking and microblogging service (using Twitter) for gradually sending key concepts to students throughout the semester (gradual learning); (b) detailed online virtual laboratory tests for a delocalized development of lab practices (self-learning); (c) integration of different complementary learning resources (e.g. videos, free software, technical regulations, etc.) using an open webpage. The complementary use to the classical teaching-learning process of these ICT resources has been highly satisfactory for students, who have positively evaluated this new approach.

The Criminalisation of Migration in Europe: A State-of-the-Art of the Academic Literature and Research. CEPS Liberty and Security in Europe No. 61, October 2013

In the last 30 years, a clear trend has come to define modern immigration law and policy. A set of seemingly disparate developments concerning the constant reinforcement of border controls, tightening of conditions of entry, expanding capacities for detention and deportation and the proliferation of criminal sanctions for migration offences, accompanied by an anxiety on the part of the press, public and political establishment regarding migrant criminality can now be seen to form a definitive shift in the European Union towards the so-called ‘criminalisation of migration’. This paper aims to provide an overview of the ‘state-of-the-art’ in the academic literature and EU research on criminalisation of migration in Europe. It analyses three key manifestations of the so-called ‘crimmigration’ trend: discursive criminalisation; the use of criminal law for migration management; and immigrant detention, focusing both on developments in domestic legislation of EU member states but also the increasing conflation of mobility, crime and security which has accompanied EU integration. By identifying the trends, synergies and gaps in the scholarly approaches dealing with the criminalisation of migration, the paper seeks to provide a framework for on-going research under Work Package 8 of the FIDUCIA project.

How much does EU citizenship cost? The Maltese citizenship-for-sale affair: A breakthrough for sincere cooperation in citizenship of the union? CEPS Liberty and Security in Europe No. 64, April/2014

How much does European citizenship cost in the EU? This was the question that has raised so much controversy over the Maltese citizenship-for-sale programme. The outright selling of Maltese nationality to rich foreigners led to unprecedented responses by the European Parliament and European Commission. This paper examines the affair and its relevance for current and future configurations of citizenship of the EU. It studies the extent to which member states are still free to lay down the grounds for the acquisition and loss of nationality without any EU supervision and accountability. It provides a comparative overview of member state schemes and the exact price for buying citizenship and a residency permit in the EU. It is argued that the EU’s intervention on the Maltese citizenship-for-sale affair constitutes a legal precedent for assessing the lawfulness of passport-for-sale or golden migration programmes in other EU member states. The affair has also revealed the increasing relevance of a set of European and international legal principles limiting member states’ discretion over citizenship matters and providing a supranational constellation of accountability venues scrutinising the impact of their decisions over citizenship of the Union. The Maltese citizenship-for-sale affair has placed at the forefront the EU general principle of sincere cooperation in nationality matters. Member states’ actions in the citizenship domain cannot negatively affect in substance the concept and freedoms of European citizenship. That notwithstanding, the European institutions’ insistence on the need for Maltese nationality law to require a ‘genuine link’ in the form of an effective residence criteria for any rich applicants to benefit from the fast-track naturalisation poses a fundamental dilemma from the angle of Union citizenship: what is this genuine link really about? And what is precisely ‘habitual’, ‘effective’ or ‘functional’ residence? It is argued that by supporting the ‘real connections’ as the most relevant standard, the European institutions may be paradoxically fuelling nationalistic misuses by member states of the ‘genuine link’ as a way to justify restrictive integration policies on the acquisition of nationality.

Toward international peace and security: Addressing the challenge of nuclear proliferation in a globalized world. ACES Working Papers, August 2010

With a growing number of threats to governance in the international system that result from globalization and technological innovation, it is no surprise that states have come to rely more heavily on each other and the global community for support. While the EU is partially constrained by the ultimate outcome of its own integration process, limited knowledge on this issue, and the national interests of its Member States, other governments are also experiencing difficulty in domestic implementation of international resolutions. To better understand the impact of the most recent sanctioning efforts, this paper will explore the development of the non-proliferation regime, examine implementation mechanisms of non-proliferation agreements, and analyze the impact of increased cooperation among states to thwart the spread of WMD technology and material. Case studies of unilateral measures undertaken by the US and EU against Iran will provide insight into the political and economic implications of economic sanctions from individual governments. New and emerging methods for limiting rogue states and non-state actors from acquiring the means to develop WMD will also be discussed in an effort to further discussion for future policy debates on this critical topic.

Citizenship Deprivation: A Normative Analysis. Liberty and Security in Europe No. 82, 19 March 2015

Most critical analyses assess citizenship-deprivation policies against international human rights and domestic rule of law standards, such as prevention of statelessness, non-arbitrariness with regard to justifications and judicial remedies, or non-discrimination between different categories of citizens. This report considers instead from a political theory perspective how deprivation policies reflect specific conceptions of political community. We distinguish four normative conceptions of the grounds of membership in a political community that apply to decisions on acquisition and loss of citizenship status: i) a ‘State discretion’ view, according to which governments should be as free as possible in pursuing State interests when determining citizenship status; ii) an ‘individual choice’ view, according to which individuals should be as free as possible in choosing their citizenship status; iii) an ‘ascriptive community’ view, according to which both State and individual choices should be minimised through automatic determination of membership based on objective criteria such as the circumstances of birth; and iv) a ‘genuine link’ view, according to which the ties of individuals to particular States determine their claims to inclusion and against deprivation while providing at the same time objections against including individuals without genuine links. We argue that most citizenship laws combine these four normative views in different ways, but that from a democratic perspective the ‘genuine link’ view is normatively preferable to the others. The report subsequently examines five general grounds for citizenship withdrawal – threats to public security, non-compliance with citizenship duties, flawed acquisition, derivative loss and loss of genuine links – and considers how the four normative views apply to withdrawal provision motivated by these concerns. The final section of the report examines whether EU citizenship provides additional reasons for protection against Member States’ powers of citizenship deprivation. We suggest that, in addition to fundamental rights protection through EU law and protection of free movement rights, three further arguments could be invoked: toleration of dual citizenship in a political union, prevention of unequal conditions for loss among EU citizens, and the salience of genuine links to the EU itself rather than merely to one of its Member States.

The South Caucasus - Between integration and fragmentation

The South Caucasus is situated at the intersection of Eurasia’s major transport and energy corridors, making it an important geostrategic region. Traditional regional actors Iran, Turkey and Russia have jostled for influence and power in the region for centuries, and are now faced with competition from the EU, China, the US and NATO. Although Armenia, Azerbaijan and Georgia have been independent for more than two decades, they still continue to feel the sway, and sometimes threat, of external actors. As a response, the three South Caucasus states have chosen very different geostrategic paths since the collapse of the Soviet Union, leaving the region more fragmented and volatile than ever. In this book, various authors offer a deep and broad understanding of the developments in the South Caucasus, analyse the different foreign trajectories that each of the three state is following, and highlight the impact of external actors’ policies.

Externality effects of information and communication technologies across country Borders

As information and communications technology (ICT) involves both traditional capital and knowledge capital, potential spillovers through various mechanisms can occur. We posit that ICT capital may boost productivity growth, not only in the home country, but also in other countries. In this paper, we provide empirical evidence of such spillovers using panel data on 37 countries from 1996 to 2004. Our results support the existence of ICT spillovers across country borders. Furthermore, we find that developing countries could reap more benefits from ICT spillovers than developed countries. This is particularly important for policy decisions regarding national trade liberalization and economic integration. Developing economies that are more open to foreign trade may have an economic advantage and may develop knowledge-intensive activities, which will lead to economic development in the long run.

User Perceptions of Privacy and Security on the Web

This paper describes an online survey that was conducted to explore typical Internet users' awareness and knowledge of specific technologies that relate to their security and privacy when using a Web browser to access the Internet. The survey was conducted using an anonymous, online questionnaire. Over a four month period, 237 individuals completed the questionnaire. Respondents were predominately Canadian, with substantial numbers from the United Kingdom and the United States. Important findings include evidence that users have tried to educate themselves regarding their online security and privacy, but with limited success; different interpretations of the term "secure Web site" can lead to very different levels of trust in a site; respondents strongly expressed their skepticism about privacy policies, but nevertheless believe that sites can be trusted to respect their stated policies; and users may confuse browser cookies with other types of data stored locally by browsers, leading to inappropriate conclusions about the risks they present.

STPA-SafeSec: Safety and Security Analysis for Cyber-Physical Systems

Cyber-physical systems tightly integrate physical processes and information and communication technologies. As today’s critical infrastructures, e.g., the power grid or water distribution networks, are complex cyber-physical systems, ensuring their safety and security becomes of paramount importance. Traditional safety analysis methods, such as HAZOP, are ill-suited to assess these systems. Furthermore, cybersecurity vulnerabilities are often not considered critical, because their effects on the physical processes are not fully understood. In this work, we present STPA-SafeSec, a novel analysis methodology for both safety and security. Its results show the dependencies between cybersecurity vulnerabilities and system safety. Using this information, the most effective mitigation strategies to ensure safety and security of the system can be readily identified. We apply STPA-SafeSec to a use case in the power grid domain, and highlight its benefits.

Particle Trajectory Tracing and Computational Electromagnetics for Accelerator and Related Technologies

The main objective of this R&D work is to simulate particle beam optics in CV-28 Cyclotron of Instituto de Engenharia Nuclear – IEN/CNEN, as a support for improvements or optimization of this particle accelerator. Besides 2D magnetostatic field computation results, the authors present an alternative method for charged particle trajectories computation in electrostatic or magnetostatic fields. This task is approached by analytical computation of trajectories, by parts, considering constant fields within each finite element. This method has some advantages over numerical integration ones: numerical miscomputation of trajectories is avoided; stability problem is also avoided, for the magnetostatic field case. Some examples are presented, including positive ion extraction from cyclotrons with strip-foil. This latter technique is an interesting alternative for upgrading positive ion cyclotrons, such as CV-28 Cyclotron. The particle trajectory computation method presented in this work is of interest not only for cyclotrons, but for accelerator and related technology, in general.

Particle Trajectory Computation for Accelerators and Related Technologies

This work reports an alternative method for single non-relativistic charged particle trajectory computation in 2D electrostatic or magnetostatic fields. This task is approached by analytical computation of particle trajectory, by parts, considering the constant fields within each finite element. This method has some advantages over numerical integration ones: numerical miscomputation of trajectories, and stability problems can be avoided. Among the examples presented in this paper, an interesting alternative approach for positive ion extraction from cyclotrons is shown, using strip-foils. Other particle optics devices can benefit of a method such the one proposed in this paper, as beam bending devices, spectrometers, among others. This method can be extended for particle trajectory computation in 3D domains.
