The variational inverse model (VIM) for data analysis was already shown to be statistically equivalent to objective analysis (OA) provided the covariance function for the OA and the VIM reproducing kernel are identical. The VIM, however does not allow a direct derivation of the error field associated with the analysis. The purpose of the paper is to extend the one to one correspondance between the two analysis shemes by proposing a heuristic statistical error expression for the VIM. The numerical efficiency on analysis and error map generation of both methods is compared on quasi-synoptic and climatological data sets. It is shown that the VIM analysis and error map generation offers interesting numerical skills in both case studies. [less ▲]

The file and the Database Mertens-Pack3 of the CEDOPAL of the University of Liège (Belgium) complement each other with a unique collection to the world, begun more than forty years ago with the Professor Paul Mertens, and ceaselessly enriched, more than 8000 photos of literary papyri, in black and white for the greater part, accompanied with their archives, that is, essentially, the enormous exchanged correspondence, since the sixties, between the CEDOPAL and the conservators of papyri. To perpetuate its collection of reproductions and give it more easily to the international scientific community, the CEDOPAL began since July, 2003, by means of a " Grant 2003 " of the International Association of Papyrologues, to digitize every photography of papyrus and to archive these images in a specialized database, which also includes informations from archival documents.

Owing to the establishment of a procedure aiming at a reduction of the medical supply (numerus clausus), the French Community of Belgium had decided to introduce, at the end of the third year of medical studies (third candidature), a procedure of selective attribution of the certificate allowing for a unlimited medical practice. We assessed the predictive value of the results obtained during and at the end of the first candidature (first year of medicine) for the attribution of this certificate. We studied the results of the 225 students enrolled in the first candidature in medicine at the University of Liege during the academic year 1997-1998, and we correlated them to the subsequent attribution (1999-2000- and 2000-2001) of the certificate. The success of the first candidature in the first or second session is an important predicting factor towards the reception of the certificate. A non-authorization to continue the studies in medicine in case of failure in the first session or a non-authorization to repeat the first candidature in case of failure in the second session would have, respectively, a negative predictive value (NPV) of 91.9% and 97.4% and would allow to restream 111 students at the end of the first session or 39 students at the end of the first candidature. The results of the preliminary assessments mode during the month of January are also highly predictive of the chances to get the certificate. Among the 160 students who have not successfully passed a minimum of 3 exams, only 14 students obtained the certificate. The restreaming of those students would correspond to a NPV of 91.2%. Students who were not successful in a minimum of 2 exams would have less than 5% chance to obtain the certificate. In this case, 109 students would be restreamed (NPV = 95.4%). In conclusion, the selection of the students who will obtain, at the end of the third year of medicine, the certificate allowing them for an unlimited medical practice is obtained, in a large proportion, during the first candidature and especially after the session of January. In view of those results and considering the decree abolishing the selection at the end of the third year of medical studies, one could argue about the appropriateness of the current procedure, chosen by the French Community of Belgium, compared to other solutions prioritising an earlier selection of the future doctors.

This symposium proposes presentations related to nurse educators competencies and the challenges links to their new roles. The evolution of the nurses training at the European level asks the teacher to develop high-level disciplinary skills but also educational skills. There are lots of challenges to develop nurse educator competencies. The role of the teachers is not any more to transmit disciplinary knowledge but to become experts in group management, colleagues teamwork, reflective practice, and construction of active learning situations in a socio constructivist model. These changes of roles also have an impact on the professional identity of the teachers. The various presentations will approach successively these ideas: 1. A proposal for a Competencies Benchmarking of Nurse Educators The aim of this presentation is to characterize the nursing teachers concepts on their professionalism,roles, competences and their identities construction. 2. Educational knowledge in teaching in nursing This presentation examine the teachers conceptions about teaching nursing and professional knowledge about teaching in higher education. 3. Construction of teaching/learning to care from the perspective of nursing teacher This presentation analyses the facilities and difficulties of nurse teacher in their role. 4.

The risks, complications and results of the transcatheter aortic valve implantation (TAVI) are widely described. But to our knowledge, no one has yet defined the nursing cares required after this procedure and their effects on the TAVI results. The aims of this review are to describe the nursing cares required after TAVI and to determine which aspects of the management could be optimized to improve the results of the procedure. [less ▲]

A theoretical model of clinical case management for psychogeriatric patients and their families is described. Psychogeriatric patients often have complex health care needs, requiring specific nursing interventions. The increasing frailty of these patients over time, together with the risk for institutionalization, make professional nursing contribution to their care even more desirable. Nursing case management is described by means of a conceptual-operational continuum. On the conceptual site, the continuum includes a geriatric definition and core principles of case management. On the operational site, case management is described as a clinical system, a process, a technology, and a role. The process of case management is a deliberate, intellectual activity whereby the practice of nursing is approached in an orderly, systematic manner. It includes components of assessment, diagnosis, planning, implementation, and evaluation. The case management approach requires nurses to assume an active role in designing care maps and to work collaboratively with members of a multidisciplinary team. [less ▲]

The numeral unit spread assessment pedigree (NUSAP) system was implemented to evaluate the quality of input parameters in a quantitative microbial risk assessment (QMRA) model for Salmonella spp. in minced pork meat. The input parameters were grouped according to four successive exposure pathways: (1) primary production (2) transport, holding, and slaughterhouse, (3) postprocessing, distribution, and storage, and (4) preparation and consumption. An inventory of 101 potential input parameters was used for building the QMRA model. The characteristics of each parameter were defined using a standardized procedure to assess (1) the source of information, (2) the sampling methodology and sample size, and (3) the distributional properties of the estimate. Each parameter was scored by a panel of experts using a pedigree matrix containing four criteria (proxy, empirical basis, method, and validation) to assess the quality, and this was graphically represented by means of kite diagrams. The parameters obtained significantly lower scores for the validation criterion as compared with the other criteria. Overall strengths of parameters related to the primary production module were significantly stronger compared to the other modules (the transport, holding, and slaughterhouse module, the processing, distribution, and storage module, and the preparation and consumption module). The pedigree assessment contributed to select 20 parameters, which were subsequently introduced in the QMRA model. The NUSAP methodology and kite diagrams are objective tools to discuss and visualize the quality of the parameters in a structured way. These two tools can be used in the selection procedure of input parameters for a QMRA, and can lead to a more transparent quality assurance in the QMRA. [less ▲]

implemented to evaluate assumptions in a quantitative microbial risk assessment (QMRA) model for Salmonella spp. in minced pork meat. This QMRA model allows the testing of mitigation strategies for the reduction of human salmonellosis and aims to serve as a basis for science-based policy making. The NUSAP method was used to assess the subjective component of assumptions in the QMRA model by a set of four pedigree criteria: ‘the influence of situational limitations’, ‘plausibility’, ‘choice space’ and ‘the agreement among peers’. After identifying 13 key assumptions relevant for the QMRA model, a workshop was organized to assess the importance of these assumptions on the output of the QMRA. The quality of the assumptions was visualized using diagnostic and kite diagrams. The diagnostic diagram pinpointed assumptions with a high degree of subjectivity and a high ‘expected influence on the model results’ score. Examples of those assumptions that should be dealt with care are the assumptions regarding the concentration of Salmonella on the pig carcass at the beginning of the slaughter process and the assumptions related to the Salmonella prevalence in the slaughter process. The kite diagrams allowed a clear overview of the pedigree scores for each assumption as well as a representation of expert (dis)agreement. The evaluation of the assumptions using the NUSAP system enhanced the debate on the uncertainty and its communication in the results of a QMRA model. It highlighted the model’s strong and weak points and was helpful for redesigning critical modules. Since the evaluation of assumptions allows a more critical approach of the QMRA process, it is useful for policy makers as it aims to increase the transparency and acceptance of management decisions based on a QMRA model.

De frequentie van het 'witte-jassen' syndroom en het belang van dit fenomeen op de bloeddrukbelasting en de variabiliteit van de arteriële bloeddruk over 24 uur werden bij 181 patiënten onderzocht gedurende een 24 uur durende ambulante bloeddrukmeting. Ondanks een goede correlatie tussen de klinische meting van de arteriële bloeddruk en de gemiddelde bloeddruk overdag of gedurende 24 uur, is er toch een tegenstrijdigheid tussen de .bloeddrukwaarden die met beide methoden worden gemeten (de klinische bloeddruk is hoger dan de ambulant gemeten bloeddruk, des te meer naarmate de klinische bloeddruk hoger is). Bij de beoordeling van de werkzaamheid van antihypertensiva blijkt uit het beloop van de bloeddruk dat een derde van de behandelde patiënten normale bloeddrukwaarden heeft, terwijl bij twee derden van de patiënten de gemiddelde bloeddruk overdag en gedurende 24 uur duidelijk hoger is dan per definitie is toegestaan. Dit onderzoek toont ook aan dat de ambulant gemeten bloeddrukwaarden (vooral de systolische bloeddruk) een beter voorspellend vermogen voor linker-ventrikelhypertrofie hebben dan de klinisch gemeten bloeddrukwaarden. Deze waarnemingen bevestigen het belang van deze niet-invasieve techniek van meting van de gemiddelde bloeddruk, zowel om het 'witte-jassen' effect te objectiveren en aldus de diagnose arteriële hypertensie te preciseren, als om na te gaan of de bloeddruk met antihypertensiva goed is ingesteld.
