Planning and scheduling Hubble Space Telescope observations is a formidable task. During the course of a year tens of thousands of exposures are taken on several thousand targets. Many observations are linked to others via scientific ``special requirements'' specified by the observer in the proposal. All observations are subject to numerous observing constraints such as Sun avoidance, occultation by the Earth, and spacecraft roll and power constraints. At the beginning of the HST mission, planning and scheduling work concentrated on the correct implementation and execution of observations. In Cycles 2 and 3 a major effort to increase the productivity of the observatory (while retaining quality) was begun and increased HST observation efficiency by about 50%. In Cycle 4, a major effort is underway to further improve the planning and scheduling process, in order to achieve stability in the observing program long-range plan, to improve the system's flexibility and responsiveness to change, and to increase visibility into the HST observing schedule as it evolves. This paper will describe the basis for these improvements, including the long-range planning criteria and timescales, the process of planning and scheduling and how changes will be supported. We will also describe the major observing constraints and how they are handled by the planning and scheduling system. Finally, we will discuss how recent advances in networking technology have made it possible to dramatically increase the ability of HST proposers to view the long- and short-range HST observing plans. Using a client program such as Mosaic or Lynx, an astronomer will be able to access a World Wide Web (WWW) server at the STScI to provide convenient access to HST observing proposals and their implementation status, and both the long-range and short-term observing schedules.

Cet article présente une amorce d’un travail de recherche plus global qui porte sur l’étude des conditions institutionnelles, cognitives et didactiques de l’introduction de la statistique inférentielle dans les programmes de l’enseignement secondaire belge. Nous proposons une analyse a priori des difficultés que pourraient rencontrer des élèves de ce niveau. Nous mettons au jour trois grands obstacles d’apprentissage : la non-prise en compte de la variabilité, le décodage d’ostensifs en termes de lecture « X-Y » plutôt qu’en termes de rapports d’aires et la difficulté à concevoir des niveaux sémantiques plus abstraits. Nous les analysons sur base de la typologie de Brousseau. Nous mettons à l’épreuve cette typologie en la complétant de ce que nous appellerons un obstacle cognitif. [less ▲]

The existing in Moldova Aurignacian industries of the lamellar type are represented by the stone collections of two kinds: with leaf-shaped points and backed points with a concave edge. Together with this the Corpach IV industry which includes backed points (segments) must have been related to Gravette. Other industries should not be considered separately and apparently can be grouped under the title "industries de type Paléolithique supérieur ancien à pointes foliacées". They are supposed to spring from the Middle Palaeolithic industries with leaf-shaped pieces (from Micoquian of Central Europe), that were further developed in the Aurignacian direction. If the Aurignacian of Moldova has evidently a foreign origin, then the Gravette traditions go back to some related centers. It is reflected in the compatibilty of backed pieces and leaf-shaped points in one and the same industry, dated back to the early stage of the Upper Palaeolithic. It is clearly seen in the collections of lower layers of Molodova V where homogeneousness of the complex is evident starting with the tenth layer. The appearance of some new types of tools (for instance, shouldered points) in the upper layers of this site does not fail the general stability and the cultural originality of the industry.

Background Drug-resistant chronic duster headache (drCCH) is a devastating disorder for which various destructive procedures have been tried unsuccessfully. Occipital nerve stimulation (ONS) is a new, safe strategy for intractable headaches. We undertook a prospective pilot trial of ONS in drCCH to assess clinical efficacy and pain perception. Methods Eight patients with drCCH had a suboccipital neurostimulator implanted on the side of the headache and were asked to record details of frequency, intensity, and symptomatic treatment for their attacks in a diary before and after Continuous ONS. To detect changes in cephalic and extracephalic pain processing we measured electrical and pressure pain thresholds and the nociceptive blink reflex. Findings Two patients were pain free after a follow-up of 16 and 22 months; one of them still had occasional autonomic attacks. Three patients had around a 90% reduction in attack frequency. Two patients, one of whom had had the implant for only 3 months, had improvement of around 40%. Mean follow-up was 15.1 months (SD 9.5, range 3-22). Intensity of attacks tends to decrease earlier than frequency during ONS and, on average, is improved by 50% in remaining attacks. All but one patient were able to substantially reduce their preventive drug treatment. Interruption of ONS by switching off the stimulator or because of an empty battery was followed within days by recurrence and increase of attacks in all improved patients. ONS did not significantly modify pain thresholds. The amplitude of the nociceptive blink reflex increased with longer durations of ONS. There were no serious adverse events. Interpretation ONS could be an efficient treatment for drCCH and could be safer than deep hypothalamic stimulation. The delay of 2 months or more between implantation and significant clinical improvement suggests that the procedure ads via slow neuromodulatory processes at the level of upper brain stem or diencephalic centres.
