Methods commonly applied to case studies are often characterized by the search for one or more solutions viewed as « the right way » to solve the problem and supported by an in-depth analysis of the causes of the problem which they aim at solving. By using different principles, we can stimulate modes of reasoning which do not follow these social and cognitive habits. Such an approach has several goals. One is to facilitate the search for solutions to a complex problem by stimulating creativity and communication between participants; another is to become better aware of our mode of discussion and spontaneous reasoning and to appreciate the value of using other modes. In this report, we discuss the application of the principle of “non-closure”, i.e. to consider that it is favorable to leave certain problems completely or slightly unresolved in order to stimulate the learning dynamics. Additionally, we discuss the application of the principle of “orientation on the solution”, which is based on adopting an approach centered on the resources, the competencies and the expectation for the future, rather than a “defect-based” approach, which centers on the causes of the problems and the deficiencies of the individuals who have to face them. Based on a case-study that took place in the framework of a training session in group facilitation, we introduce a new method, called « Yes, but… ». This method is characterized by the fact that it allows the analysis of a situation by combining both principles introduced above. We discuss the mode of application of this approach as well as its conceptual and praxeological implications. [less ▲]

The Institute of Astrophysics of the University of Liege has been present at the High Altitude Research Station Jungfraujoch, Switzerland, since the late 1940s, to perform spectrometric solar observations under dry and weakly polluted high-mountain conditions. Several solar atlases of photometric quality, extending altogether from the near-ultra-violet to the middle-infrared, were produced between 1956 and 1994, first with grating spectrometers then with Fourier transform instruments. During the early 1970s, scientific concerns emerged about atmospheric composition changes likely to set in as a consequence of the growing usage of nitrogen-containing agricultural fertilisers and the industrial production of chlorine-bearing compounds such as the chlorofluorocarbons and hydro-chlorofluorocarbons. Resulting releases to the atmosphere with ensuing photolysis in the stratosphere and catalytic depletion of the protective ozone layer prompted a worldwide consortium of chemical manufacturing companies to solicit the Liege group to help in clarifying these concerns by undertaking specific observations with its existing Jungfraujoch instrumentation. The following pages evoke the main steps that led from quasi full sun-oriented studies to priority investigations of the Earth's atmosphere, in support of both the Montreal and the Kyoto Protocols.

A number of recent studies suggest that some ‘vegetative state’ patients have been misdiagnosed, judging by their ability to follow commands and in some cases even communicate through brain activity. Such studies highlight the difficulty in forming a diagnosis based only on behavioral assessments. We think that neuroimaging and electrophysiology methods will be used more frequently in clinical settings, integrated with existing behavioral assessments. Such efforts are expected to lead to a more accurate understanding of individual patients’ cognitive abilities or even provide prognostic indicators. In terms of treatment planning (i.e., pain management and end-of-life decision-making), patients with disorders of consciousness are now offered the possibility of expressing their preferences by means of brain–computer interfaces. What remains to be clarified is the degree to which such indirect responses can be considered reliable and of legal representation. [less ▲]

Between 1947 and 1991, soils of Belgium were mapped to establish a systematic inventory of the country soil resources. Field observations were done by soil auger to a standard depth of 1.25 m and at a mean density of 2 points per hectare. Cadastral plans at scale 1:5,000 where used for georeferencing field observations and for delimiting map units, subsequently generalized on the 1:10,000 topographic base map. The final map was published on sheets at scale 1:20,000 along with descriptive texts. Besides, data on about 15,000 described and analyzed soil profiles were reported in technical annexes. With the advent of computers, data on soil profiles have been transfered into relational databases and soil sheets have been digitized. Coding of the data rendered them more accessible, but inevitably implied a standardization and hence a reduction of some information. Still most of the soil surveyors have already passed away, besides their intangible expert knowledge, a wealth of information is also being lost when their field notes, unpublished reports, minutes of meetings and draft maps are being disregarded. The map legend was developed during the first decade of the survey, reflecting state of knowledge on soil formation and their relative importance for agricultural land-use in the 1950s. To guarantee that future generations will be able to appreciate the value and concepts underpinning the soil information, it is important that at least a minimum set of such historical documents would be preserved, analyzed and documented.

The network of ASPAs (Antarctic Specially Protected Areas) that is presently under construction in the frame of the Committee for Environmental Protection of the Antarctic Treaty is intended to protect "outstanding environmental, scientific, historic, aesthetic or wilderness values, any combination of those values, or ongoing or planned scientific research" (http://www.ats.aq/e/ep_protected.htm). When the Madrid Protocol was signed, twenty-one years ago, the knowledge on the biodiversity of tiny and microscopic organisms was much less extensive and molecular methods for biodiversity assessments were only in their infancy. The majority of the permanent inhabitants of Antarctica are, however, essentially microscopic. [less ▲]

An original experimental setup for shearography with metrological applications is presented herein. The simplicity and the efficiency of the setup are provided by a shearing device, a prism that separates the TE and TM polarization modes with a coating and a thin glass plate attached on its face. The temporal phase shifting method is applied through the use of a liquid crystal variable retarder. The use of this shearing device enables an in-line and almost-common path configuration for the shearing interferometer, a path that leads to high stability of the interferometer and a low sensitivity to external disturbances. In order to prove the efficiency and the accuracy of this speckle shearing interferometer, the out-of-plane displacement derivative relative to the shearing interferometry direction of a centrally loaded steel plate has been measured by the shearographic interferometer and then compared with the out-of-plane displacement derivative computed from the displacement field provided by the finite element method. The results are in good agreement. [less ▲]

This paper presents a formal framework for identifying and filtering SPIT calls (SPam in Internet Telephony) in an outbound scenario with provable optimal performance. In so doing, our work is largely different from related previous work: our goal is to rigorously formalize the problem in terms of mathematical decision theory, find the optimal solution to the problem, and derive concrete bounds for its expected loss (number of mistakes the SPIT filter will make in the worst case). This goal is achieved by considering an abstracted scenario amenable to theoretical analysis, namely SPIT detection in an outbound scenario with pure sources. Our methodology is to first define the cost of making an error (false positive and false negative), apply Wald’s sequential probability ratio test to the individual sources, and then determine analytically error probabilities such that the resulting expected loss is minimized. The benefits of our approach are: (1) the method is optimal (in a sense defined in the paper); (2) the method does not rely on manual tuning and tweaking of parameters but is completely self-contained and mathematically justified; (3) the method is computationally simple and scalable. These are desirable features that would make our method a component of choice in larger, autonomic frameworks. [less ▲]

OBJECTIVE: To describe outcome of treatment with propofol and phenobarbital for status epilepticus (SE) after portosystemic shunt (PSS) attenuation. CASE OR SERIES SUMMARY: Three dogs without preceding seizure activity, were diagnosed with a single extrahepatic PSS. Following standard preoperative medical therapy, an ameroid constrictor was placed surgically. Recovery was uneventful until spontaneous SE developed 46-96 hours after surgery. After unsuccessful seizure control with benzodiazepines, dogs were treated with a bolus of propofol followed by a propofol constant rate infusion. Phenobarbital was concurrently administered and supportive care was optimized. All dogs recovered uneventfully over the next 7-9 days. Over the following months phenobarbital was slowly tapered. All dogs have been free from antiepileptic drugs for several months, without recurrence of neurologic signs. NEW OR UNIQUE INFORMATION PROVIDED: In this case series, we describe the treatment of 3 dogs with propofol and phenobarbital for refractory SE following attenuation of a single congenital PSS. After weaning of the propofol constant rate infusion, and tapering and discontinuation of phenobarbital over the following months, all dogs experienced a complete recovery. This study provides evidence that use of propofol in combination with phenobarbital may be efficacious for management of SE in dogs after PSS surgery. [less ▲]
