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 ▲]

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 ▲]

It is commonly known that experiencing conflict can have negative impact on an individuals’ physical and mental health. Especially in intimate relationships, conflict has great influence on the well-being of both partners. Since intercultural intimate relationships are associated with both exceptional obstacles and benefits, conflict behavior in those relationships is of substantial interest in this research project. The aim of this study is to investigate how conflicts in intimate relationships are affected by the partners’ cultural backgrounds and linguistic barriers. It further seeks to unravel how conflict resolution is approached in order to provide a broader knowledge base in this field. For the purpose of this research, four semi-structured interviews with two couples were conducted individually. Each couple was interviewed by a different researcher. Ensuing, the interviews were transcribed and afterwards the data was analyzed implementing qualitative content analyses. The results provide insight into different levels of relationship functioning, sources of conflict as well as conflict resolution. Therefore, the findings of this study may have important implications for clinical practice. [less ▲]

Differences in culture and mother tongue can have an important impact on the dynamics of an intercultural relationship. In this study the focus lies on the influence of culture and language on expressing love and affection and on other factors like commitment and romantic beliefs in intercultural romantic relationships, and the conflicts that might occur due to the cultural and linguistic differences in intercultural romantic relationships. Two intercultural couples participated in this study. They were interviewed using a semi-structured approach and were recorded. These were transcribed and coded with the coding scheme based on the Grounded Theory. The findings suggest that culture and language have a quite significant influence on expressing love and affection in intercultural romantic relationships. Furthermore, cultural and linguistic differences can have an influence on becoming committed to another person. The expression of romantic beliefs can also be influenced by the different cultural backgrounds. Cultural and linguistic differences can predict conflicts in intercultural romantic relationships. In this study, barriers in communication, differences in religion and different perspectives on concepts such as homosexuality are at the core of these conflicts. [less ▲]

Current humor research tends to accentuate the positive and neglect the negative. Often, the healing power is in the center of humor research; however, less is reported about the negative effects humor can have if not used adequately. In particular, less is known about the appropriate and in-appropriate use of humor in an intercultural context. The purpose of this bachelor thesis was to bridge this lack in humor research by trying to identify the fine line between appropriate and in-appropriate humor. If humor is used appropriately, it can have a huge power to bridge cultural divides. Thus, this thesis aimed as well to investigate the use of humor as a coping strategy in intimate intercultural couples. Thirdly, additional functions of humor shall be explored. Semi-structured, focused interviews were conducted with two intimate intercultural couples. Participants were of Irish, Luxembourgish, German and French-Canadian nationality. Interview data was then analyzed using qualitative content analysis. Results revealed that the appropriate use of humor depends on personal, linguistic, and cultural factors. Overall, self-deprecating humor seems to be the safest type of humor, whereas sarcasm can be experienced as hurtful even if not intended to be. Ethnic humor can have positive effects, too, if it is directed versus the own culture and not versus foreign cultures. Moreover, results revealed that humor mainly serves two functions in intimate intercultural relationships: the one of bonding and the one of coping. Humor as a coping strategy can be used internally, hence related to relationship issues, as well as externally, thus related to external stressors. One can conclude that the function of bonding and coping cannot be clearly distinguished. Consequently, it proves that humor can be a useful tool in bridging intercultural and interpersonal divides. Limitations of the study clearly lie in its sample size, which does not allow to draw any generalizations. In the future, similar studies with a larger sample size as well as with non-Western cultures would be interesting to investigate in the future. [less ▲]

There has not yet been any research done on future planning in international and intercultural couples. The purpose of this case study is to give a first insight into the process of future planning in intercultural couples. A qualitative case study with two participants, one from New Zealand and one from Belgium who are immigrating to New Zealand. One interview with each participant was held before the couple moved to New Zealand for three months and one more interview with each participant after they returned. Results are plentiful. A clear sign that different cultural backgrounds influence future planning seems to exist. Further the couple reported multiple projects and events in which decision making, goal hierarchy and future planning existed. Not all results have been analysed and are available for further use.This case study offers a first insight into future planning of international and intercultural couples. The next step would be to try to support the findings with quantitative data. [less ▲]
