The socio-economic field researches have indicated the necessity of realizing an integrated consultancy service for beekeepers that will supply technical-economic solutions with a practical character for ensuring the lucrativeness and viability of the apiaries. Consequently, an integrated apiarian consultancy model has been built holding the following features: it realizes the diagnosis of the meliferous resources and supplies solutions for its optimal administration; it realizes the technical-economic of the apiarian exploitation adapted according to its objectives and identifies its optimal administration measures; it manages the local pollination services market; it realizes viable investment projects and ensures the management of their implementation; it elaborates aggregated indicators as efficient instruments of analysis and utilizes and informatics application of apiarian management used for realizing the specific objectives of the apiaries; it integrates the technical, economic and juridical consultancy service.

Uncertainty assessments in groundwater modeling applications typically attribute all sources of uncertainty to errors in parameters and inputs, neglecting what may be the primary source of uncertainty, namely, errors in the conceptualization of the system.Confining the set of plausible system representations to a single model leads to underdispersive and prone-to-bias predictions. In this work, we present a general and flexible approach that combines generalized likelihood uncertainty estimation (GLUE) and Bayesian model averaging (BMA) to assess uncertainty in model predictions that arise from errors in model structure, inputs, and parameters. In a prior analysis, a set of plausible models is selected, and the joint prior input and parameter space is sampled to form potential simulators of the system. For each model, the likelihood measures of acceptable simulators, assigned to thembased on their ability to reproduce observed systembehavior, are integrated over the joint input and parameter space to obtain the integrated model likelihood. The latter is used to weight the predictions of the respective model in the BMA ensemble predictions. For illustrative purposes, we applied the methodology to a three-dimensional hypothetical setup. Results showed that predictions of groundwater budget terms varied considerably among competing models; despite this, a set of 16 head observations used for conditioning did not allow differentiating between the models. BMA provided average predictions that were more conservative than individual predictions obtained for individual models. Conceptual model uncertainty contributed up to 30% of the total uncertainty. The results clearly indicate the need to consider alternative conceptualizations to account for model uncertainty. [less ▲]

Depuis quelques années, les recherches sur les inégalités existant entre les individus par rapport à leur santé se focalisent sur l’influence exercée par les conditions sociales tout au long du cycle de vie. En somme, c’est l’aspect dynamique de la santé qui est de plus en plus privilégié. Cependant, la collecte d’un événement de santé au moyen de l’approche biographique a été rarement mise en oeuvre dans les recueils biographiques. La présente note vise à présenter le cheminement conceptuel et la démarche méthodologique que nous avons suivis pour définir un événement de santé et l’intégrer dans une enquête biographique mise en place en Belgique. La première partie de cette note présente succinctement les définitions allouées à l’état de santé d’un individu. La deuxième partie met en lumière les avantages et les limites de la collecte longitudinale et montre l’intérêt de l’approche biographique. La troisième partie, enfin, est consacrée à la présentation de l’approche innovatrice que nous avons mise en oeuvre, autour de l’idée des interruptions d’activités, pour collecter un événement de santé dans un dispositif biographique.

Cette communication se focalisera sur la préparation au métier de formateur d’enseignants organisée notamment dans le cadre d’un module intitulé « Didactique Professionnelle et Formation Initiale des enseignants » du master en Sciences de l’Education de l’université de Liège (ULg – Belgique). La première partie de ce module privilégie le développement chez les futurs formateurs d’une compétence clé à nos yeux : « Accompagner chaque futur enseignant dans la conceptualisation et la régulation de son activité professionnelle ». Cette compétence est à la fois travaillée sur le terrain (cette année, en classes maternelles) et à l’ULg. Certaines séances de cours dispensées aux futurs formateurs les mettent face à des tâches complexes, proches de celles qu’ils auront à gérer pendant les accompagnements. Elles sont amorcées par des mises en situations ou par des récits exemplaires de pratiques récoltés auprès de formateurs d’enseignants chevronnés. D’autres séances de cours sont destinées à garantir des ressources conceptuelles (didactique professionnelle, utilisation délibérative et non applicationniste de la théorie, caractéristiques du métier enseignant, développement des compétences professionnelles, construction identitaire, …) et techniques (entretien d’explicitation, utilisation des ressources pédagogiques sur Internet, construction d’outils d’observation, utilisation de la caméra, …) à mobiliser dans les tâches complexes puis sur le terrain. Pendant l’accompagnement, l’exploitation par les futurs formateurs de traces (données d’observation, enregistrements vidéos et audios) soutient des entretiens de régulation individualisés et une séance d’analyse de pratiques en petits groupes. Quand un observable soutient la réflexion, on peut faire l’hypothèse qu’il favorise la conceptualisation voire même le changement du cadre interprétatif, particulièrement quand le groupe des pairs introduit des perceptions différentes, des significations autres et suggère des pistes d’actions alternatives.

The Mediterranean seagrass Posidonia oceanica (L.) Delile is regarded as a relevant indicator of bioavailable trace elements (TEs) since it efficiently and proportionally bioaccumulates these chemicals from its surrounding environment. Recent studies have further brought supplementary insights in our understanding of the processes driving TE kinetics within that species. But at a higher degree of organization, the distribution and flows of TEs between P. oceanica meadow components, i.e. seagrass shoots, epiphytes, associated algae and animals and detritus, have not been investigated yet. The present study therefore aims to propose a conceptualization model of P. oceanica meadows, regarded as the juxtaposition of the 5 separate components listed above exchanging flows of TEs between themselves and with their environment, i.e. water and sediment. This model can be drawn in energy circuit language. By writing such a model, one in essence is writing equations describing a system. To be relevant, its elaboration requires the compilation of a large amount of quantitative data. This conceptualization can thus be regarded as a collaborative innovation requiring scientists to fill the model through the continuous supplement of new data. In fine, this model will lead to the exact quantification of the role played by P. oceanica meadows in the coastal biogeochemistry of TEsin the Mediterranean. [less ▲]

The paper provides a framework for the conceptualization, definition and measurement of the legacy costs that needs to be addressed in a reform that transforms an unfunded (or non‐financial) defined benefit (NDB) scheme into an equally unfunded notional (or non‐financial) defined contribution (NDC) scheme. During a transition from NDB to NDC a financing gap typically arises due to accrued to date liabilities from the old system in excess of the NDC scheme’s sustainable flow of benefits. This gap ‐ or legacy cost ‐ needs to be estimated and financed. We illustrate different techniques to gauge the scope of the cost. The paper applies the proposed approach to a hypothetical NDC reform in China. [less ▲]

Previous research has shown that the content and frequency of mind-wandering episodes—the occurrence of thoughts that are both stimulus-independent and task-unrelated—are closely related to an individual’s future-related concerns. Whether this relationship is shaped by the affective changes that are usually associated with future-related concerns still remains unclear, however. In this study, we induced the anticipation of a negatively valenced event and examined whether the ensuing affective changes were related to the occurrence and content of mind-wandering during an unrelated attentional task. We found that the increase in negative affect following concern induction predicted the general frequency of mind-wandering episodes. Furthermore, mind-wandering episodes specifically directed at the induced concern were related to a lower decrease in negative affect during the attentional task. These results suggest that the negative emotional impact of future-related concerns is an important factor to be taken into consideration for the subsequent occurrence of mind-wandering episodes, which might in turn be involved in the maintenance of negative affect over time.

BACKGROUND/AIMS: Few data are available about parental concerns and psychosocial functioning of young children born small for gestational age (SGA) treated with growth hormone (GH). The present study focused on the perception of short stature and the concerns and expectations of the parents regarding GH treatment. METHODS: Forty prepubertal short SGA children, randomized into a GH-treated and a GH-untreated group, and their parents were evaluated by a questionnaire and a semi-structured interview at start and after 2 years of follow-up. RESULTS: Before start, 85% of the parents were concerned about short stature, 76% expected an increase in adult height of > or =10 cm and 81% expected a positive impact on well-being. Half of the parents expressed fears regarding GH treatment. After 2 years, more parents of treated children reported obvious growth and physical changes, and fewer parents reported teasing because of short stature. An improvement of well-being was reported by half of the parents of treated and untreated children. Fears about GH treatment disappeared almost completely. CONCLUSION: The perspective of GH treatment induced major adult height expectations. In treated children, the physical effects of GH treatment became obvious, teasing because of short stature decreased and initial concerns about short stature and GH therapy decreased. [less ▲]
