Inside the Belgian reform of mental health care delivery: network coordinators This article analyses the Belgian reform of mental health care delivery as a two steps-translation (Callon 1986): the problematization – the devising of a new mental health care model by policy makers, and the interessement – through which “local coordinators” tried to interest local actors to the new model. Based on empirical data, two evidences are stressed: the coordination function is conceived in different ways, ranging from intermediaries to mediators; and the interessement is influenced by systems of concrete action (Friedberg, 1997). Thus, it is argued that in case where translators are appointed to interest local actors to a problematization from the policy arena, their performance is better appraised by considering their commitment to behave as faithful intermediaries or as strategic mediators, and the informal games regulating their system of action.

This paper presents an inverse modelling approach for parameter estimation of a model dedicated to the description of moisture mass transfer in porous hygroscopic building materials. The hygric behaviour of unfired clay-based masonry samples is specifically studied here and the Moisture Buffer Value (MBV) protocol is proposed as a data source from which it is possible to estimate several parameters at once. Those include materials properties and experimental parameters. For this purpose, the mass of two clay samples with different compositions is continuously monitored during several consecutive humidity cycles in isothermal conditions. Independently of these dynamic experimental tests, their moisture storage and transport parameters are measured with standard steady-state methods. A simple moisture transfer model developed in COMSOL Multiphysics is used to predict the moisture uptake/release behaviour during the MBV tests. The set of model parameters values that minimizes the difference between simulated and experimental results is then automatically estimated using an inverse modelling algorithm based on Bayesian techniques. For materials properties, the optimized parameters values are compared to values that were experimentally measured in steady state. And because a precise understanding of parameters is needed to assess the confidence in the inverse modelling results, a sensitivity analysis of the model is also provided. [less ▲]

Due their productivity, structural diversity, and potential to promote ecological, functional and morphological evolution, coral reefs have the highest species richness of fishes. As swimming is the primary form of locomotion and interaction their aquatic environment, small morphological variations can have profound implications on the fitness of fishes. The damselfish family, Pomacentridae, has inhabited coral reef ecosystems for more than 50 million years. As such, habitat preferences and behavior could significantly contribute to the evolution of the morphology of damselfish through the impacts of shape on locomotion. To test this hypothesis, we employed comparative morphometric analyses of fish shape and ecology. While body elongation represented the primary source of variation in locomotor system shape, results also showed a diverse suit of morphological combinations in between the morphological extremes. Results showed strong associations between behavior and habitat preferences, suggesting that behavior may constrain the shape of the locomotor system in damselfishes. Position in the water column show relation with the cephalic region and truck, behavior is related to the cephalic angle and the angle of insertion of the pectoral fin, while maximum depth is related to the caudal peduncle. Was found little relation between the caudal peduncle, the angle of pectoral fin attachment and the rest modules, therefore, this two modules may be the main responsible of swimming fitness in damselfishes. Finally, cephalic region is highly related to most modules, especially to trunk. This strong integration may be responsible of the limit morphological variation of damselfishes. [less ▲]

Large-scale epistasis studies can give new clues to system-level genetic mechanisms and a better understanding of the underlying biology of human complex disease traits. Though many novel methods have been proposed to carry out such studies, so far only a few of them have demonstrated replicable results. Here, we propose a minimal protocol for genome-wide association interaction (GWAI) analysis to identify gene–gene interactions from large-scale genomic data. The different steps of the developed protocol are discussed and motivated, and encompass interaction screening in a hypothesis-free and hypothesisdriven manner. In particular, we examine a wide range of aspects related to epistasis discovery in the context of complex traits in humans, hereby giving practical recommendations for data quality control, variant selection or prioritization strategies and analytic tools, replication and meta-analysis, biological validation of statistical findings and other related aspects. The minimal protocol provides guidelines and attention points for anyone involved in GWAI analysis and aims to enhance the biological relevance of GWAI findings. At the same time, the protocol improves a better assessment of strengths and weaknesses of published GWAI methodologies. [less ▲]

This paper considers a trajectory-based approach to determine control signals superimposed to those of existing controllers so as to enhance the damping of electromechanical oscillations. This approach is framed as a discrete-time, multi-step optimization problem which can be solved by model-based and/or by learning-based methods. This paper proposes to apply a model-free tree-based batch mode Reinforcement Learning (RL) algorithm to perform such a supplementary damping control based only on information collected from observed trajectories of the power system. This RL-based supplementary damping control scheme is first implemented on a single generator and then several possibilities are investigated for extending it to multiple generators. Simulations are carried out on a 16-generators medium size power system model, where also possible benefits of combining this RL-based control with Model Predictive Control (MPC) are assessed.

Conducting round robin exercises is one of EGOLF's key activities. A round robin exercise is a necessary tool to improve and maintain a good level of quality within EGOLF. A good plan of the round robin exercise will make the work easier, and will help avoid problems and misunderstandings. The intention is to give general guidelines on how to organize round robins in a standardized way within EGOLF. The document is divided into the following parts - Preparing and planning the round robin - Testing - Data analysis and reporting These guidelines comply with the ISO 5725 prescriptions. [less ▲]

The prevalence of valvular heart diseases reaches 2.5% in the overall population. Aortic valve replacement is one of the most common surgical procedures. We report the story of a female patient whose aortic mechanical valve, implanted at the age of 54 years at the time of a mitral valve repair surgery, had to be replaced 14 years later, due to the development of a subvalvular pannus narrowing the valvular orifice. We use this clinical story to compare the advantages and disadvantages of repair surgery and valve replacement with a biological or mechanical prosthesis, and summarize the latest evidence for the choice of the most adequate prosthesis for a particular patient’s profile.
