Digital design tools are nowadays deeply rooted in most architectural design processes. Either used as a way to communicate a designed artifact, or rather as a medium to test innovative morphologies (lately referred to as non-standard architecture), these design tools profoundly shape the way architects envision complexity all along their day-to-day tasks. The large teams of "star-architects" were able to develop dedicated and specific strategies and digital tools to overcome some of the technological gaps they were faced to when using commercial packages. But how are small and medium firms dealing with the inherent complexities of such software? This contribution analyzes how those firms (and more specifically the Walloon ones) deal with the growing complexity of digital tools, both in terms of use and interdisciplinarity. [less ▲]

L’image de Charles Martel pilleur d’Église figure encore dans bon nombre de nos manuels et grandes synthèses historiques. Il en va de même de celle de l’avènement de Pépin III à la royauté, élu par un peuple franc unanime, sur un précepte du pape Zacharie, et oint par Boniface. Or, de multiples questions ont été soulevées, ces dernières années, de nouvelles orientations de recherche ont été suggérées, qui constituent un pressant appel à un nouvel examen de la crédibilité des sources principales de l'histoire du royaume franc. Selon toute vraisemblance, la conviction des Carolingiens de détenir leur pouvoir directement de Dieu ne remonte pas au-delà du changement de dynastie mais n’est pas née ex nihilo. Elle plonge ses racines dans les décennies qui précédèrent le coup d’État de 751. L’alliance franco-pontificale de 754 fut, de toute évidence, l’aboutissement d’une transformation progressive de l’attitude des Pippinides à l’égard de Rome, du sentiment religieux et de leur rapport au sacré. À la fois typologie de sources et florilège, ce volume entend donner un aperçu de l’ampleur et de la diversité du corpus de sources à ceux et celles qui souhaiteraient aborder ce pan de l’histoire politico-religieuse du haut Moyen Âge, en présentant vingt-six sources du VIIIe siècle – narratives, diplomatiques, épistolaires ou liturgiques – traduites et commentées, retenues pour leur caractère exemplatif.

L’année 2012 marque un double anniversaire: 40 ans d’existence du Front National (FN) français, 30 ans d’existence médiatique. Cette communication tente de montrer en quoi la communication du FN paraît particulièrement bien adaptée aux logiques médiatiques. Il s’agit de réévaluer le « contrat de mariage » FN/médias à la lumière des évolutions récentes qui ont affecté leurs relations depuis que Marine Le Pen a repris le flambeau, de manière à éclairer, plus généralement, les conditions médiatiques d’existence des partis dits « populistes ». J’évoquerai les mutations récentes de la communication du FN, sur le plan des discours et des relations avec les journalistes, avant d’aborder l’évolution concomitante du traitement médiatique de Marine Le Pen. À partir de là sera posée la question de la diffusion des idées frontistes dans l’espace médiatique, envisagée comme le produit d’une interaction entre les instances politique, médiatique et citoyenne – l’ « opinion publique » saisie par les sondages. Je tâcherai alors de faire le point sur les différentes logiques médiatiques qui tendent à valoriser le parti, avant de conclure par quelques considérations sur les défis que représentent pour les journalistes les métamorphoses actuelles du FN.

What, if any, makes the unity and cohesion of the Brentano School? Is there a distinctive mark of what may be called the Brentanian philosophical orientation—or Brentanism for short? In this chapter, I argue that those questions are best answered in terms of metaphilosophical claims, claims about what philosophy is and how it should be best carried out—descriptive and normative claims. The proposal I wish to make, in sum, is the following: (i) all the members of the Brentano School share a specific conception of philosophy, and (ii) only they share this conception. To begin, I briefly contrast this approach with those seeking the criterion of Brentanism in doctrinal or merely methodological claims. I then identify a cluster of nine metaphilosophical and epistemological claims arguably endorsed by all the members of the school. [less ▲]

This chapter examines the dominant continuity of the EU’s transformative policy in Ukraine during the crisis in Ukraine. Natorski scrutinizes how the Euromaidan revolution, the annexation of Crimea and the war in Donbass affected the dynamics of EU policy reproduction since 2013 and explains the EU-Ukraine-Russia discussions on the potential trade consequences of the Deep and Comprehensive Free Trade Area. The dynamics of the continuity of the EU policy towards Ukraine and the altered role of Russia are explained in terms of the discursive representations of the crisis in Ukraine by the EU. The chapter concludes that the policy reproduction and change depend on what actors make of the crisis and to what extent crisis representation can be mediated coherently through the background discursive schemes.

This paper examines the dynamic trading strategies implemented by hedge fund managers using a Kalman filter of hedge fund betas across styles. We further investigate the risk drivers of dynamic trades, examining which conditioning/macroeconomic variables strongly lead the time variation in fund trades. We report the significance of macroeconomic factors such as interest rates, dividend yield, GDP growth and US unemployment. We show that hedge fund managers do control the intensity of their exposures according to economic uncertainty and that differences between up- and down-market regimes can be observed. Commonly, Hedge funds tend to dislike high-dividend paying stocks. Besides, all hedge fund styles are shown to display pro-cyclical exposures towards directional equity factors as well as credit and liquidity risks. Small growth stocks, however, are revealed to be crisis investments whose allocation increases with unemployment, inflation or volatility. As volatility increases, the value of growth options embedded into growth stocks indeed increases. Growth stocks are shown to hedge market reversals and volatility. The outperformance of growth companies in recessions might also relate to their cost flexibility. Allocation to small stocks embed strong micro risks and might also constitute a hedge in economic slowdowns. This might explain why some funds with such a particular investment focus appear to be countercyclical. [less ▲]

Stock and option markets can at times reflect differing information. We identify three reasons for the presence of these periods of "disagreement" between the cash and derivatives markets: 1) high volatility and noise trading; 2) high level of risk aversion; 3) speculation versus hedging trades. This paper investigates the role that hedge funds, a proxy for sophisticated investors, play in the price discovery process between stock and option markets and the disagreement/agreement periods. We observe that a disparity in information between the two markets is often associated with deleveraging in directional exposures and reversal strategies. Posterior to the event, active tactical asset allocation in small and value factor investing takes place. We investigate four specific macro events which resulted in significant rebalancing by hedge fund manegers: the Thai Baht depreciation, the Dot-com bubble, the credit crunch and the Nasdaq correction.

We characterize pairs of complementary non-homogeneous Beatty sequences $(A_n)_{n>0}$ and $(B_n)_{n>0}$, with the restriction $A_1=1$ and $B_1\geq 3$, for which there exists an invariant take-away game having $\{(A_n,B_n),(B_n,A_n)\mid n> 0\}\cup\{(0,0)\}$ as set of $P$-positions. Using the notion of Sturmian word arising in combinatorics on words, this characterization can be translated into a decision procedure relying only on a few algebraic tests about algebraicity or rational independence. This work partially answers to a question of Larsson et al. raised in Larsson et al. [less ▲]

In this paper, we present an optimized retrieval strategy for carbonyl sulfide (OCS), using Fourier transform infrared (FTIR) solar observations made at the high-altitude Jungfraujoch station in the Swiss Alps. More than 200 lines of the nu3 fundamental band of OCS have been systematically evaluated and we selected 4 microwindows on the basis of objective criteria minimizing the effect of interferences, mainly by solar features, carbon dioxide and water vapor absorption lines, while maximizing the information content. Implementation of this new retrieval strategy provided an extended time series of the OCS abundance spanning the 1995-2015 time period, for the study of the long-term trend and seasonal variation of OCS in the free troposphere and stratosphere. Three distinct periods characterize the evolution of the tropospheric partial columns: a first decreasing period (1995-2002), an intermediate increasing period (2002-2008), and the more recent period (2008-2015) which shows no significant trend. Our FTIR tropospheric and stratospheric time series are compared with new in situ gas chromatography mass spectrometry (GCMS) measurements performed by Empa (Laboratory for Air Pollution/Environmental Technology) at the Jungfraujoch since 2008, and with space-borne solar occultation observations by the ACE-FTS instrument on-board the SCISAT satellite, respectively, and they show good agreement. The OCS signal recorded above Jungfraujoch appears to be closely related to anthropogenic sulfur emissions. [less ▲]

Les troubles du sommeil sont fréquents chez l’enfant et leurs origines sont diverses. Ces troubles ont leur ancrage dans le développement neurophysiologique et psychoaffectif de l’enfant. Les enfants souffrant de troubles du spectre autistique présentent un déficit de sommeil, qui peut durer jusqu’à l’adolescence. Les troubles du spectre autistique comportent des comorbidités multiples, dont des altérations du sommeil. Ils sont importants à caractériser dans cette population, car ils peuvent avoir un impact négatif sur les comportements diurnes. Par ailleurs, ils entrainent souvent des difficultés au sein de la famille. La prise en charge doit avant tout prendre en compte le contexte environnemental afin d’améliorer les habitudes et l’hygiène du sommeil. Des questionnaires ainsi que des agendas de sommeil ont été remplis par des parents afin de démontrer l’importance d’une évaluation et d’une prise en compte des troubles du sommeil chez les enfants souffrant d’autisme en consultation pédopsychiatrique.
