L’arabe de Tripoli contemporain possède divers marqueurs qui permettent d’exprimer différents futurs : le participe actif, la conjugaison préfixale nue et trois préverbes (b-, ḥā- et taw-). Le but de cette étude est de déterminer précisément la ou les fonction(s) de chacun de ces marqueurs, afin d’en préciser le sémantisme, par le biais d’une approche transcatégorielle, qui considère la façon dont vont s’entrecroiser les catégories du temps, de l’aspect et des modalités. Ces catégories linguistiques coexistent et se manifestent à des degrés différents, permettant à quatre « futurs » de se distinguer : le participe actif exprime l’aspect prospectif et nomme un procès situé en contigüité avec le moment d’énonciation, avec valeur de certitude ; la conjugaison préfixale nue exprime un futur aspectuel en rupture avec le moment de l’énonciation, donc non certain ; le préverbe ḥā- exprime un futur de certitude, mais en rutpure avec le moment d’énonciation ; le préverbe taw- exprime un futur d’engagement : l’énonciateur s’engage au moment de l’acte de parole à réaliser une action dans un futur situé en rupture avec le moment d’énonciation, donc dans le domaine du non certain. Quant au préverbe b-, il dit l’intention ; il marque en outre l’antériorité dans les subordonnées temporelles ; il exprime enfin l’éventuel et l’irréel.

A linguistic corpus gathered from recordings of spontaneous exchanges between young single men in Tripoli reveals everyday language as it is evolving, which serves to speak about sexuality as well as events that are not sexual in nature. Taboo words are recurrent in the sociolect studied. The terms zəbb, zəbr, kāțu “cock” et dlāwəz “balls” are used in interjective, adverbial and adjectival locutions. The noun gaḥba “whore” is used in interjective locutions. Related verbs (gəḥḥəb and tgəḥḥəb) are desemanticized and grammaticalized. The verb nāk “to fuck” is also grammaticalized and changes categories from simple verb to support verb to serial verb.

Because the initial phase of barrier reef evolution is often buried under more recent phases of coralgal growth, the origin of modern barrier reefs has remained elusive. Direct observations on the nature of the substrate on top of which barrier reefs have developed are lacking, and simple questions whether substrate controls or even dictates their overall linear morphology have remained unanswered. NSF MARGINS and IMAGES funded 2004 PANASH and 2005 PECTEN cruises on the R/V Melville and on the N/O Marion Dufresne, respectively, surveyed the shelf edges in the Gulf of Papua at the northern extremities of the Great Barrier Reef and PNG Barrier Reef. In the northern part of Ashmore Trough, the surveys uncovered a 30 to 50 m-high ridge that parallels the shelf edge with linear segments exceeding 10 km in length. Analyses of a core, recovered in a re-entrant in front of the ridge, demonstrate that a coastline, essentially siliciclastic, reached the present-day shelf break during Last Glacial Maximum -LGM and the Oldest Dryas -OD (17.5-16.5 cal. ky. BP.). During a major pulse of sea level rise, between ~ 16.0 and 13.0 ky cal. ky. BP, a coralgal reef established itself on top of a LGM/OD siliciclastic beach barrier complex, and subsequently drowned. On the northwest PNG shelf edge, an early transgressive, as thick as 30 m, coralgal edifice complex, sampled at its flank by a piston core at ~ 107 m below modern sea level, established itself on top of a LGM shelf edge delta lobe, partially eroded and located at about 120-125 m below modern sea level.

We assessed a notetaking intervention targeting the passive learning style and disruptive behaviors exhibited by adolescents with attention deficit hyperactivity disorder (ADHD) in school. Teens with ADHD were able to learn the notetaking strategies through the use of a modification of the Directed Notetaking Activity (Spires & Stone, 1989). Furthermore, measures of comprehension and disruptive behavior improved as a function of both the product and process of the notetaking procedures. We discuss individual differences as well as implications for integrating psychoeducational, behavioral, and pharmacological interventions for adolescents with ADHD.

The Gaussian factor copula model is the market standard model for multi-name credit derivatives. Its main drawback is that factor copula models exhibit correlation smiles when calibrating against market tranche quotes. To overcome the calibration deficiency, we introduce a multi-period factor copula model by chaining one-period factor copula models. The correlation coefficients in our model are allowed to be timedependent, and hence they are allowed to follow certain stochastic processes. Therefore, we can calibrate against market quotes more consistently. Usually, multi-period factor copula models require multi-dimensional integration, typically computed by Monte Carlo simulation, which makes calibration extremely time consuming. In our model, the portfolio loss of a completely homogeneous pool possesses the Markov property, thus we can compute the portfolio loss distribution analytically without multi-dimensional integration. Numerical results demonstrate the efficiency and flexibility of our model to match market quotes.

The aim of the paper is to introduce techniques in order to tune sequential in-core sorting algorithms in the frameworks of two applications. The first application is parallel sorting when the processor speeds are not identical in the parallel system. The second application is the Zeta-Data Project (Koskas , 2003) whose aim is to develop novel algorithms for databases issues. About 50% of the work done in building indexes is devoted to sorting sets of integers. We develop and compare algorithms built to sort with equal keys. Algorithms are variations of the 3way-Quicksort of Segdewick. In order to observe performances and to fully exploit functional units in processors and also in order to optimize the use of the memory system and the different functional units, we use hardware performance counters that are available on most modern microprocessors. We develop also analytical results for one of our algorithms and compare expected results with the measures. For the two applications, we show through fine experiments on an Athlon processor (a three-way superscalar x86 processor), that L1 data cache misses is not the central problem but a subtil proportion of independent retired instructions should be advised to get performance for in-core sorting.
