This Book provides a new analysis of the role that the British played in the shift in American foreign policy from 1946 to 1950. To achieve this shift (which also included support of British strategic interests in the Eastern Mediterranean) this book argues that the British used Greece, first as a way to draw the United States further into European affairs, and then as a way to anchor the United States in Europe, achieving a guarantee of security of the Eastern Mediterranean and of Western Europe. While trying to understand and explain the origins and dynamics of Anglo-American foreign policy in the pre and early years of the Cold War, the role that perception played in the design and implementation of foreign policy became a central focus of the research. From this point came the realization of a general lack of emphasis and research into the ways in which the British government managed to convince the United States government to assume support for worldwide British strategic objectives. How this support was achieved is the central theme of this book. It also addresses the question of whether or not Anglo-American policy was simply a convergence of common Anglo-American objectives, or if it was a result of common objectives created by British influence? To support these hypotheses, this work uses mainly the British and American documents relating to Greece from 1946 to 1950 to explain how these nations made and implemented policy towards Greece during this crucial period in history. In so doing it also explains how American foreign policy in general changed from its pre-war focus on non-intervention, to the post-war policy which heavily favours intervention. [less ▲]

Dans le présent article nous tenterons de dresser le portrait des situations d’utilisation du français dans l’océan Pacifique, dans une approche écologique, dynamique et holistique. Nous présenterons brièvement l’évolution historique et politique de chaque aire francophone, de son degré de francophonie et des liens qui existent entre le français et les autres langues parlées à chaque endroit, selon les domaines et fonctions d’utilisation. Certaines parties de cette vaste région se caractérisent par le tissage d’un réseau actif de relations interinsulaires. La Polynésie en est l’illustration type, alors qu’en revanche les espaces insulaires de la Mélanésie ont davantage tendance à être repliés sur eux-mêmes. [less ▲]

A new method is proposed for characterising local urban patterns at the scale of a large urban region. The approach overcomes the difficulties of surface-based representations of built-up morphologies and provides an efficient way to account for the proximity of built and non-built land. The strength of the approach resides in the direct use of the coordinates of each building, a very parsimonious input of external parameters, and a local spatial statistical perspective. The method consists in, first, constructing and clumping the Minimum Spanning Tree (MST) that links each building to its neighbours in order to obtain connected urban and suburban graph subsets, and second, measuring a Local Index of Spatial Association (LISA) on inter-building distances in order to characterise patterns. The method differentiates heterogeneous settlements from statistically significant homogeneous clusters with either long or short connections between buildings. The method is applied to the Southern periphery of Brussels (Belgium). [less ▲]

In this paper, we consider optimal transceiver design and relay selection for simultaneous transfer of data and energy in a cooperative network consisting of amplify-and-forward (AF) relays. In this context, we address two different problems and propose optimal relay selection and transceiver processing. Furthermore, the problems are formulated for both time switching (TS) and power splitting (PS) schemes. The first problem is the maximization of overall rate while ensuring a minimum harvested energy at the receiver. For this problem, we perform computations of optimal fractions to distribute the received signal corresponding to TS and PS schemes, the relay weighing coefficients, and optimal relay selection. In the second problem, optimal resource allocation for maximizing the overall harvested energy at the user under constraints on the minimum achievable rate has been formulated. For this problem, we propose a suitable solution to meet the requirements for both TS and PS. For both the problems, we obtain a closed form solution. Finally, the performance of proposed design under various operating conditions and parameter values are illustrated with a comparison between TS and PS schemes. [less ▲]

This article examines national identity construal processes within the case study context of Luxembourg. Building on research highlighting the modalities of generalization from case studies, I present the country case that is Luxembourg. This social universe has a foreign population percentage of 47% and what is considered majority and minority becomes increasingly fluid. The migration process itself is fluid, ranging from daily migration, to medium-term stays, return visits and permanent immigration including uptake of citizenship. Within such a fluid environment, where national borders are permeable at the physical level of crossing borders and (national) societies are nested within societies, culture contact is a permanent feature in daily life. Nationality becomes a salient feature as culture contact tends to prompt reflection, resulting in questioning and (re-)negotiation of national identity. This affects the native population as well as the diverse immigrant population – with diversity going beyond the level of country of origin. Many individuals are also of mixed nationality and some examples for the construal process of national identity will be provided, illustrating how national identity is negotiated at individual level. Like a periscope, this country let s us adjust mirrors, permitting us to observe modes of identity construal which would otherwise be obstructed from the field of view. The case study that is Luxembourg allows us to look at the micro-setting of the construction, potentially of something new. [less ▲]

Many studies suggest using coverage concepts, such as branch coverage, as the starting point of testing, while others as the most prominent test quality indicator. Yet the relationship between coverage and fault-revelation remains unknown, yielding uncertainty and controversy. Most previous studies rely on the Clean Program Assumption, that a test suite will obtain similar coverage for both faulty and fixed (‘clean’) program versions. This assumption may appear intuitive, especially for bugs that denote small semantic deviations. However, we present evidence that the Clean Program Assumption does not always hold, thereby raising a critical threat to the validity of previous results. We then conducted a study using a robust experimental methodology that avoids this threat to validity, from which our primary finding is that strong mutation testing has the highest fault revelation of four widely-used criteria. Our findings also revealed that fault revelation starts to increase significantly only once relatively high levels of coverage are attained. [less ▲]

There is an emerging need to perform high frequency scattering analysis on high-fidelity models. Conventional Finite Element analysis suffers from irretrievable loss of the boundary accuracy as well as pollution error. Man-made geometries can be represented exactly in Isogeometric Analysis (IGA) with no geometrical loss even with very coarse mesh. The aim of this paper is to analyze the accuracy of IGA for exterior acoustic scattering problems. The numerical results show extremely low pollution error even for very high frequencies. [less ▲]

While the direct impact of innovation on growth has been examined in entrepreneurship literature, the underlying channels of influence have remained largely unexplored. This article draws upon Behavioral Reasoning Theory to examine whether growth intention is the pathway through which product, process and organizational innovations influence venture growth or not. Results from the analysis of a dataset of 20,472 French new ventures reveal that: (1) product, process and organizational innovations have a positive impact on sales revenue growth; (2) growth intention has a positive impact on sales revenue growth; and (3) growth intention mediates the effects of product and organizational innovations on sales revenue growth. These findings have implications for a more balanced and nuanced view on how innovations impact new venture growth. [less ▲]

In this paper we demonstrate the ability of a derivative-driven Monte Carlo estimator to accelerate the propagation of uncertainty through two high-level non-linear finite element models. The use of derivative information amounts to a correction to the standard Monte Carlo estimation procedure that reduces the variance under certain conditions. We express the finite element models in variational form using the high-level Unified Form Language (UFL). We derive the tangent linear model automatically from this high-level description and use it to efficiently calculate the required derivative information. To study the effectiveness of the derivative-driven method we consider two stochastic PDEs; a one- dimensional Burgers equation with stochastic viscosity and a three-dimensional geometrically non-linear Mooney-Rivlin hyperelastic equation with stochastic density and volumetric material parameter. Our results show that for these problems the first-order derivative-driven Monte Carlo method is around one order of magnitude faster than the standard Monte Carlo method and at the cost of only one extra tangent linear solution per estimation problem. We find similar trends when comparing with a modern non-intrusive multi-level polynomial chaos expansion method. We parallelise the task of the repeated forward model evaluations across a cluster using the ipyparallel and mpi4py software tools. A complete working example showing the solution of the stochastic viscous Burgers equation is included as supplementary material. [less ▲]

Previous research has tested the effects of video games on players’ Rape Myth Acceptance (RMA) with regard to either sexual or violent contents. The current study aimed at investigating the combined effects of sexual and violent material in video games on players’ RMA. Participants (N = 82) played either a sexualized female game character or a non-sexualized female game character in a violent video game. Participants’ pre-gaming RMA, gender role attitudes and gaming habits were found to predict RMA after the gaming episode, but sexualized game violence did not. Furthermore, no gender differences were found with regard to RMA. The present findings corroborate the important role of pre-existing gender attitudes for the concept of RMA. In addition, future research should also focus on long-term exposure to video games and players’ gaming habits when examining the effects of sexualized violence in video games on RMA. [less ▲]

Constraint solving is an essential technique for detecting vulnerabilities in programs, since it can reason about input sanitization and validation operations performed on user inputs. However, real-world programs typically contain complex string operations that challenge vulnerability detection. State-of-the-art string constraint solvers support only a limited set of string operations and fail when they encounter an unsupported one; this leads to limited effectiveness in finding vulnerabilities. In this paper we propose a search-driven constraint solving technique that complements the support for complex string operations provided by any existing string constraint solver. Our technique uses a hybrid constraint solving procedure based on the Ant Colony Optimization meta-heuristic. The idea is to execute it as a fallback mechanism, only when a solver encounters a constraint containing an operation that it does not support. We have implemented the proposed search-driven constraint solving technique in the ACO-Solver tool, which we have evaluated in the context of injection and XSS vulnerability detection for Java Web applications. We have assessed the benefits and costs of combining the proposed technique with two state-of-the-art constraint solvers (Z3-str2 and CVC4). The experimental results, based on a benchmark with 104 constraints derived from nine realistic Web applications, show that our approach, when combined in a state-of-the-art solver, significantly improves the number of detected vulnerabilities (from 4.7% to 71.9% for Z3-str2, from 85.9% to 100.0% for CVC4), and solves several cases on which the solver fails when used stand-alone (46 more solved cases for Z3-str2, and 11 more for CVC4), while still keeping the execution time affordable in practice.

To reduce the effort developers have to make for crash debugging, researchers have proposed several solutions for automatic failure reproduction. Recent advances proposed the use of symbolic execution, mutation analysis, and directed model checking as underling techniques for post-failure analysis of crash stack traces. However, existing approaches still cannot reproduce many real-world crashes due to such limitations as environment dependencies, path explosion, and time complexity. To address these challenges, we present EvoCrash, a post-failure approach which uses a novel Guided Genetic Algorithm (GGA) to cope with the large search space characterizing real-world software programs. Our empirical study on three open-source systems shows that EvoCrash can replicate 41 (82%) of real-world crashes, 34 (89%) of which are useful reproductions for debugging purposes, outperforming the state-of-the-art in crash replication.

Lighting is an essential community service, but current implementations are not energy efficient and impact on the energy budget of the municipalities for at least 40\%. In this paper, we propose heuristics and devise a comparison methodology for new smart lighting solutions in next generation smart cities. The proposed smart lighting techniques make use of Internet of Things (IoT) augmented lamppost, which save energy by turning off or dimming the light according to the presence of citizens. Assessing costs and benefits in adopting the new smart lighting solutions is a pillar step for municipalities to foster real implementation. For evaluation purposes, we have developed a custom simulator which enables the deployment of lampposts in realistic urban environments. The citizens travel on foot along the streets and trigger activation of the lampposts according to the proposed heuristics. For the city of Luxembourg, the results highlight that replacing all existing lamps with LEDs and dimming light intensity according to the presence of users nearby the lampposts is convenient and provides an economical return already after the first year of deployment.

A novel Phase Center Motion (PCM) based technique for discriminating angle-Doppler signatures within Multiple-Input-Multiple-Output (MIMO) radars using Frequency Modulated Continuous Wave (FMCW) has been explored in this work. The PCM technique induces angle dependent Doppler shifts in the back-scattered signal, wherein a modified Doppler post processing for FMCW leads to joint angle-Doppler processing. Specifically, we intend to design unique spatialtemporal motion of the phase center on each individual MIMO radar channel in an effort to synthesize nearly orthogonal angle- Doppler signatures. Subsequently, we also develop a MIMO radar receiver design, which would be capable of discriminating between these induced angle-Doppler signatures. The asymptotic investigation provides a Bessel function characteristic. Simulation results demonstrate a significant side-lobe suppression of 8:5 dB for an individual PCM trajectory and 7 dB over distinct PCM trajectories, in an attempt towards realization of nearly orthogonal MIMO radar channels.
