This paper investigates the suitability of clayey materials originating from semi-arid soil and river sediments, used by potters in the Agafay region for the manufacture of ceramic products. The clay samples were subjected to particle-size analysis, X-ray diffraction and X-ray fluorescence to investigate their physical, mineralogical and chemical characteristics respectively. The physical behaviour of the intermediate products was studied at the shaping and drying stages of the ceramics manufacturing process through the Atterberg limits and the plot of the Bigot curve respectively. The final product characteristics were determined through porosity tests, flexural and compressive strengths tests. Based on results obtained, the raw materials turn out to be suitable characteristics for the manufacture of earthenware products. The application of the suggested recommendations is worthy for the improvement of the products based on such raw materials. [less ▲]

It has recently become possible to monitor patients’ voices outside the speech therapist’s office with a portable, easy-to-use tool: the voice dosimeter. This tool measures voice frequency and sound pressure level, as well as the duration of phonation, during a full day of regular activities. In addition to voice accumulation in an ecological context, the dosimeter used in this study (VoxLog, Sonvox) gives patients feedback on their voice use. In practice, the clinician configures the device so that it provides a vibratory signal in real time when the patient speaks above or below a predetermined frequency or sound pressure threshold. The feedback is intended to make patients aware of inappropriate vocal behavior and encourage them to change it. In this case study, we used biofeedback with the aim of reducing sound pressure level for a teacher suffering from vocal fold nodules. Our goal was to determine whether vibrotactile biofeedback applied in an ecological context for three consecutive weeks could reduce excess sound pressure. The feedback was activated every time the teacher spoke too loudly; its purpose was to help her avoid vocal abuse and (re)learn healthy vocal behaviors. This preliminary study generated encouraging results regarding the use of biofeedback in voice treatment. Nevertheless, it is important to investigate how this tool can best be implemented for patient management in speech language pathology. In addition, the method should be validated with randomized studies using a larger sample. [less ▲]

As the need for faster power system dynamic simulations increases, it is essential to develop new algorithms that exploit parallel computing to accelerate those simulations. This paper proposes a parallel algorithm based on a two-level, Schur complement-based, domain decomposition method. The two-level partitioning provides high parallelization potential (coarse and fine-grained). In addition, due to the Schur-complement approach used to update the sub-domain interface variables, the algorithm exhibits high global convergence rate. Finally, it provides significant numerical and computational acceleration. The algorithm is implemented using the shared-memory parallel programming model, targeting inexpensive multi-core machines. Its performance is reported on a real system as well as on a large test system combining transmission and distribution networks. [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.
