In the present survey paper, we give a short, yet exhaustive state-of-the-art about the cyber-security applied to control systems, especially the event-based strategy. Indeed, in the past few years, due to a highest degree of connectivity in modern systems, new related control-specific cyber-physical systems security challengesarise and novel approaches integrating the cyber aspect are developed.Our goal in this paper is then to provide an overview of attack-modeling and security analysis approaches in recent works thatexplore networked control systems subject to cyber-attacks attacks. To this end, we look at the control, estimation, and modeling problems. [less ▲]

After World War II, as Europe floundered economically, British Prime Minister Clement Attlee looked to disengage Britain from some of its broad international obligations and increase American support for its new foreign agenda. One place he sought to do so was in Greece, which was in the midst of a civil war. Through an in-depth study of Anglo-American diplomacy in Greece from 1946-50, Spero Simeon Z. Paravantes reveals how the relationship between Britain and the US developed in this formative period. He argues that, in many ways, Britain used the fast-escalating tensions of (what would become) the Cold War to direct and manipulate US policy in Greece, encouraging the Americans to take a more active role and (essentially) take Britain's place in the region. In the process, he sheds fresh light onto how the American experience in Greece contributed to the formulation of the Truman Doctrine, the infamous NSC-68 document and the ultimate birth of the Cold War. Drawing on a wide range of sources from Britain, the US, Greece and across the Balkans, Paravantes has produced the first book to focus on this crucial period in such close detail, and reveals the ways in which various foreign and domestic concerns coincided at a pivotal moment of twentieth century history. This book is essential reading for all scholars looking to gain fresh insight into post-WWII Greece, the Anglo-American alliance and the complex origins of the Cold War. [less ▲]

Regional (sub-)groupings have played a significant, but comparatively neglected role in the processes of European integration. The BENELUX and the Nordic Council both offer longstanding models of regional cooperation which have, in various ways, often been cited as examples for the wider European integration project. More recently, both the Visegrád and Baltic states have seen the (re-) emergence of forms of regional cooperation in connection with their accession to and later membership of the European Union. Yet, though often cited, these experiences of (sub-)regional cooperation within the wider European project have been the object of relatively little systematic or comparative study. The aim of the edited volume is to address this gap by bringing together specialists on these regional groupings with a view to providing a fuller understanding of both their historical significance and their possible future role relative to a potentially fragmenting European political landscape.

This paper argues, against existing literature, that 17th-cent. constcamer paintings were objects to think with, functioning as the two-dimensional space of artificial memory. In turn, these artworks complicate conventional definitions of epistemic images more broadly. I focus on an analysis of constcamer paintings accounting for the reception of the ancients and the mnemonic and propaedeutic role of images, entailing concepts such as wonder or thauma (from Greek θεάομαι), the drive to gather knowledge, memory as the locus of this ‘collection’, and recollecting as the intellectual process of interaction with memorized knowledge. The term inventor, referring to the creator of a given collection, is derived from the rhetorical technique for the retrieval of information. The theatre or ‘place for viewing’ provided the physical context for the collected wisdom. Inventors of constcamer paintings – often artists themselves – vitally participated in knowledge formation contributing to contemporary intellectual debates. [less ▲]

Security testing verifies that the data and the resources of software systems are protected from attackers. Unfortunately, it suffers from the oracle problem, which refers to the challenge, given an input for a system, of distinguishing correct from incorrect behavior. In many situations where potential vulnerabilities are tested, a test oracle may not exist, or it might be impractical due to the many inputs for which specific oracles have to be defined. In this paper, we propose a metamorphic testing approach that alleviates the oracle problem in security testing. It enables engineers to specify metamorphic relations (MRs) that capture security properties of the system. Such MRs are then used to automate testing and detect vulnerabilities. We provide a catalog of 22 system-agnostic MRs to automate security testing in Web systems. Our approach targets 39% of the OWASP security testing activities not automated by state-of-the-art techniques. It automatically detected 10 out of 12 vulnerabilities affecting two widely used systems, one commercial and the other open source (Jenkins). [less ▲]

Background: Suicide is the second leading cause of death in adolescents. Screening for persons at risk usually includes asking about suicidal ideation, which is considered inappropriate in some societies and situations. To avoid directly addressing suicide, this paper investigates whether the Health Behaviour in School-aged Children Symptom Checklist (HBSC-SCL), a validated non-clinical measure of eight subjective health complaints (e.g. headache, feeling low), could be used as a tool for screening suicidal ideation and behavior in adolescents. Methods: 5262 secondary school students aged 12-18 answered the Luxembourgish HBSC 2014 survey, including the HBSC-SCL items and suicidal ideation and behavior questions. Results: Each HBSC-SCL item correlates with suicidal ideation and behavior. A sum score was calculated ranging from zero to eight health complaints to predict respondents who considered suicide (area under the ROC curve = .770). The ideal cut-off for screening students who consider suicide is three or more health complaints: sensitivity is 66.3%, specificity is 75.9% and positive predictive value is 32.9%. Limitations: One limitation is HBSC-SCL's low positive predictive value. This is a general problem of screening rare events: the lower the prevalence, the lower the positive predictive value. Sensitivity and specificity could be improved by taking age-, gender- and country-specific cut-off values, but such refinements would make the score calculation more complicated. Conclusions: The HBSC-SCL is short, easy to use, with satisfactory screening properties. The checklist can be used when suicide cannot be addressed directly, and also in a more general context, e.g. by school nurses when screening adolescents. [less ▲]

The objective of this paper is to evaluate option pricing model performance at the cross sectional level. For this purpose, we propose a statistical framework, in which we in particular account for the uncertainty associated with the reported pricing performance. Instead of a single figure, we determine an entire probability distribution function for the loss function that is used to measure option pricing model performance. This methodology enables us to visualize the effect of parameter uncertainty on the reported pricing performance. Using a data driven approach, we confirm previous evidence that standard volatility models with clustering and leverage effects are sufficient for the option pricing purpose. In addition, we demonstrate that there is short-term persistence but long-term heterogeneity in cross-sectional option pricing information. This finding has two important implications. First, it justifies the practitioner’s routine to refrain from time series approaches, and instead estimate option pricing models on a cross-section by cross-section basis. Second, the long term heterogeneity in option prices pinpoints the importance of measuring, comparing and testing option pricing model for each cross-section separately. To our knowledge no statistical testing framework has been applied to a single cross-section of option prices before. We propose a methodology that addresses this need. The proposed framework can be applied to a broad set of models and data. In the empirical part of the paper, we show by means of example, an application that uses a discrete time volatility model on S&P 500 index options. [less ▲]

This chapter seeks to investigate whether the proximity of a border can be seen as an engine of regional development, or a disruptive element. The impacts of cross-border activity on demographic evolution but also on unemployment or economic activity at the French–Luxembourgish border will be identified. Quantitative data from the municipal level (French census for 2014) will be used, with a special focus on the French border municipality of Longwy (formerly one of the main steel-producing areas in France).
