BACKGROUND. No study to date has assessed the impact of skills acquisition after a communication skills training program on physicians' ability to detect distress in patients with cancer. METHODS. First, the authors used a randomized design to assess the impact, on physicians' ability to detect patients' distress, of a 1-hour theoretical information course followed by 2 communication skills training programs: a 2.5-day basic training program and the same training program consolidated by 6 3-hour consolidation workshops. Then, the investigate contextual, patient, and communication variables or factors associated with physicians' detection of patients' distress were investigated. After they attended the basic communication skills training program, physicians were assigned randomly to consolidation workshops or to a waiting list. Interviews with a cancer patient were recorded before training, after consolidation workshops for the group that attended consolidation workshops, and approximate to 5 months after basic training for the group that attended basic training without the consolidation workshops. Patient distress was recorded with the Hospital Anxiety and Depression Scale before the interviews. Physicians rated their patients' distress on a visual analog scale after the interviews. Physicians' ability to detect patients' distress was measured through computing differences between physicians' ratings of patients' distress and patients' self-reported distress. Communication skills were analyzed according to the Cancer Research Campaign Workshop Evaluation Manual. RESULTS. Fifty-eight physicians were evaluable. Repeated -measures analysis of variance showed no statistically significant changes over time and between groups in physicians' ability to assess patient distress. Mixed-effects modeling showed that physicians' detection of patients' distress was associated negatively with patients' educational level (P = 0.042) and with patients' self-reported distress (P < 0.000). Mixed-effects modeling also showed that physicians' detection of patient distress was associated positively with physicians breaking bad news (P = 0.022) and using assessment skills (P = 0.015) and supportive skills (P = 0.045). CONCLUSIONS. Contrary to what was expected, no change was observed in physicians' ability to detect distress in patients with cancer after a communication skills training programs, regardless of whether physicians attended the basic training program or the basic training program followed by the consolidation workshops. The results indicated a need for further improvements in physicians' detection skills through specific training modules, including theoretical information about factors that interfere with physicians' detection and through role-playing exercises that focus on assessment and supportive skills that facilitate detection.

Reinforcement learning consists of a collection of methods for approximating solutions to deterministic and stochastic optimal control problems of unknown dynamics. These methods learn by experience how to adjust a closed-loop control rule which is a mapping from the system states to control actions. This paper proposes an application of reinforcement learning methods to the control of a FACTS device aimed to damp power system oscillations. A detailed case study is carried out on a synthetic four-machine power system. [less ▲]

Paedomorphosis, the presence of ancestral larval and juvenile traits that occur at the descendent adult stage, is an evolutionary phenomenon that shaped morphological evolution in many vertebrate lineages, including tailed amphibians. Among salamandrid species, paedomorphic and metamorphic phenotypes can be observed within single populations (facultative paedomorphosis). Despite wide interest in facultative paedomorphosis and polymorphism produced by heterochronic changes (heterochronic polymorphism), the studies that investigate intraspecific morphological variation in facultative paedomorphic species are largely missing. By quantifying the cranium size and development (bone development and remodeling), we investigated the variation at multiple levels (i.e., between sexes, populations and species) of two facultatively paedomorphic European newt species: the alpine and the smooth newt. The pattern of variation between paedomorphs (individuals keeping larval traits at the adult stage) and metamorphs (metamorphosed adult individuals) varied between species and among populations within a single species. The patterns of variation in size and skull formation appear to be more uniform in the alpine than in the smooth newt, indicating that developmental constraints differed between species (more pronounced in alpine than in smooth newt). Our study shows that the cranial skeleton provides detailed insight in the pattern of variation and divergence in heterochronic polymorphism within and between species and open new questions related to heterochronic polymorphism and evolution of cranial skeleton.

Paedomorphosis in newts and salamanders is defined as the retention of larval morphology in reproductive adults. In Triturus, Paedomorphosis is facultative because some larvae transform while other retain larval characteristics such as gill slits and mature as Paedomorph. This heterochronic process is thought to be an important micro- and macroevolutionary mechanism. In a population of a French alpine lake (le lac de la Cabane), Alpine newt Paedomorphs (Triturus a. alpestris) are abundant and coexist with a Metamorph minority. The coexistence of both morphs and the dominance of one on the other beg a few questions such as what ecological factors favour the paedomorph strategy. In this study, we analysed the feeding and spatial distribution of the Paedomorphs and Metamorphs of the Lac de la Cabane in June, July, August and October 1998. Newts were caught in the main four microhabitats of the lake : the shore, the bottom (3-7 meters deep), the water column and the surface, at dawn, during the day and in the evening. In this way, we caught 1481 newts to record their spatial position. We flushed the stomachs of 822 of these newts (the total prey number identified is more than 60 thousand). The feeding strategies of Metamorphs and Paedomorphs are very different : while Paedomorphs prey principally on plankton (Daphnia, Chydorus, ...), Metamorphs prey on a lot of exogenous invertebrates (flyes, aphids, ...). This characteristic is observed for males, females and juveniles. Cladocerans are also eaten by Metamorphs, but in much smaller quantity. The Paedomorph newts live in all the microhabitats of the lake while Metamorphs are hardly ever found on the deep bottom and in the water column. The spatial niche of Metamorphs is thus smaller than that of Pedomorphs. The data presented here suggest that the success of both morphs can be strongly influenced by environmental conditions, and that Paedomorphosis may be maintained and favoured by the spatial and feeding advantages of Paedomorphs into a deep lake.

Feeding habits and micro-habitat use were compared between metamorphs and paedomorphs in a population of the Alpine newt, Triturus a. alpestris in the French Alps. This population occupies a deep Alpine lake. The paedomorphs largely outnumbered the metamorphs. Whereas paedomorph diet was mainly composed of plankton, that of metamorphs was especially composed of larval and adult insects. The spatial use of the habitat also differed between the two forms: the paedomorphs occupied all the micro-habitats (shore, bottom, water column and surface) while the metamorphs were only found along the shore and at the water surface. In such a deep lake paedomorphosis may have persisted because of a different use of both feeding resources and micro-habitat [less ▲]

Peut-on réellement prétendre qu'en contexte de formation à distance (FAD) l'interactivité brise la distance ? En théorie, une démarche de conception de FAD axée à la fois sur le respect de critères ergonomiques, sur des stratégies et des outils stimulant l'activité des apprenants et la communication entre acteurs du dispositif va dans ce sens. Encore faut-il la mettre concrètement en oeuvre. Cet article traite de l'interactivité comme solution aux diverses contraintes rencontrées par les apprenants en situation de FAD. Les auteurs alimentent leurs réflexions au travers de champs disciplinaires variés tels que l'ergonomie des interfaces homme-machine, la psychopédagogie et la communication (synchrone et asynchrone). Dans chacun de ces champs, ils répertorient quelques bonnes pratiques pour la conception d'un dispositif de FAD « interactive ». [less ▲]

The fading of modern laboratory-synthesized and commercial Prussian blue, iron(III) hexacyanoferrate(II), based pigments in a linseed oil medium during exposure to light has been investigated. The Prussian blue pigments were painted from linseed oil, as a pure pigment and mixed with white lead, (PbCO3)2Pb(OH)2, zinc white, ZnO, or titanium white, TiO2, pigment. The samples were subjected to accelerated ageing for 800 hours and the light fastness of the Prussian blue pigment was evaluated by reference to blue wool standards. Pure Prussian blue is extremely light fast whilst it strongly fades when mixed with a white pigment, especially with lead white or zinc oxide. The painted samples were studied by UV-visible, iron K-edge X-ray absorption, iron-57 transmission Mössbauer, and attenuated total reflectance infrared spectroscopy. X-ray absorption results reveal a decrease in the iron coordination number in aged samples in the presence of white pigment. The Mössbauer spectra of the pure Prussian blue and the unaged and aged mixtures of Prussian blue and lead white or zinc oxide at 1:100 and 1:10 dilution ratios, respectively, indicate the presence of iron(II) and iron(III) in a ratio close to one as expected for the bulk stoichiometric KFeIII[FeII(CN)6]; no change in the spectral parameters was observed upon ageing. Combined with the X-ray near edge absorption and infrared studies, these results suggest reduction of the surface iron ions in the Prussian blue with ageing upon exposure to light. [less ▲]
