An innovative versatile strategy using Total Error has been proposed to decide about the method’s validity that controls the risk of accepting an unsuitable assay together with the ability to predict the reliability of future results. This strategy is based on the simultaneous combination of systematic (bias) and random (imprecision) error of analytical methods. Using validation standards both types of error are combined through the use of a prediction interval or β-expectation tolerance interval. Finally, an accuracy profile is built by connecting, on one hand all the upper tolerance limits, and on the other hand all the lower tolerance limits. This profile combined with pre-specified acceptance limits allows to evaluate the validity of any quantitative analytical method and thus their fitness for their intended purpose. In this work, the approach of accuracy profile was evaluated on several types of analytical methods encountered in pharmaceutical industrial field and also covering different pharmaceutical matrices. The four studied examples depicted the flexibility and applicability of this approach for different matrices ranging from tablets to syrups, different techniques such as liquid chromatography, or UV spectrophotometry and for different categories of assays commonly encountered in the pharmaceutical industry that are content assays, dissolution assays and quantitative impurity assays. The accuracy profile approach assesses the fitness of purpose of these methods for their future routine application,. It also allows to select the most suitable calibration curve, to evaluate adequately a potential matrix effect and propose efficient solution and to define correctly the limits of quantification of the studied analytical procedures.

The article examines the strengths and weaknesses of the concept of ‘flexicurity’, calling into question the tendency of the contemporary cultural imagination to regard flexibility as a framework for the expression of individual freedom. It then describes a range of possible policy options, in relation to the market, in the perspective of combining flexibility of labour and security of persons. Tree major options emerge: the ‘procedural’, the ‘neo-substantive’ and the ‘partnership’ options. As a conclusion, this article comes out in favour of different policy which would alter the framework for public intervention. It specially underlines the need for a ‘flexible’ and ‘decentred’ Welfare State, capable of supporting and encompassing forms of regulation emanating from civil society, in particular – but not exclusively – from the social partners.

The multicolored Asian ladybeetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), aggregates inside dwellings and buildings during winter to survive cold. This adaptive behavior causes annoyances to the occupants because of their large number and the induction of allergic reactions. Although this species has aroused a great interest these last years, the factors involved in the selection of its overwintering sites remain misunderstood. The work presented herein was oriented to the study of the non-volatile chemical compounds involved in this aggregation behavior. Chemical analyses revealed the occurrence, in aggregation sites, of an area marking made up of saturated and unsaturated hydrocarbons. Behavioral investigations demonstrated that H. axyridis preferentially aggregates in sites previously marked by congeners, indicating the retention potential of this blend on overwintering individuals. In the second instance, the same analyses were performed on an area marking aged of one year. The chemical investigations showed that only saturated hydrocarbons can still be detected after that period of time but the remaining blend does not induce aggregation anymore. This difference of response according to the freshness of the area marking suggests that this species would not be prisoner of the marking previously deposited on the substrate if the surrounding has changed and the site is not suitable anymore.

In the analysis of survival data, it is usually assumed that any unit will experience the event of interest if it is observed for a sufficiently long time. However, it can be explicitly assumed that an unknown proportion of the population under study will never experience the monitored event. The promotion time model, which has a biological motivation, is one of the survival models taking this feature into account. The promotion time model assumes that the failure time of each subject is generated by the minimum of N independent latent event times with a common distribution independent of N. An extension which allows the covariates to influence simultane- ously the probability of being cured and the latent distribution is presented. The latent distribution is estimated using a flexible Cox proportional hazard model where the logarithm of the baseline hazard function is specified using Bayesian P-splines. Introducing covariates in the latent distribution implies that the population hazard function might not have a proportional hazard structure. However, the use of P- splines provides a smooth estimation of the population hazard ratio over time. The identification issues of the model are discussed and a restricted use of the model when the follow up of the study is not sufficiently long is proposed. The accuracy of our methodology is evaluated through a simulation study and the model is illustrated on data from a Melanoma clinical trial. [less ▲]

Multiple organ procurement techniques are increasingly popular in many transplant centers. This paper describes a technique for multiorgan unit(s) explantation in rats. The procedure involves in situ preliminary dissection, cold perfusion of the thoracic and abdominal organ units as separate procedures, explantation, and finally the ex situ isolation of various organ units as single and/or multiple organ combination units. The procedure is feasible, allows for flexibility in the separation of combination organ units, and is reproducible. The exercise is provided as a training and research tool for clinical and research transplant surgeons. The technique is also presented as an animal model for clinical organ sharing. [less ▲]

The class of materials combining high electrical or thermal conductivity, optical transparency and flexibility is crucial for the development of many future electronic and optoelectronic devices. Silver nanowire networks show very promising results and represent a viable alternative to the commonly used, scarce and brittle indium tin oxide. The science and technology research of such networks are reviewed to provide a better understanding of the physical and chemical properties of this nanowire-based material while opening attractive new applications.

This paper describes the construction of a simulation model for intensive management of even)aged stands of spruce (Picea abies Karst). The model differs from many others in the way it attempts to reach predetermined objectives fixed by the manager. It starts from stand constraints issued from inventories (number of stems, mean diameter, dominant height, age) and silvicultural constraints (annual diameter increment, rotation age, thinning cycle, thinning type). A computer program using the principles of numerical thinnings has been developed to calculate at different ages : the removed material (number of stems and basal area per hectare, mean diameter, etc.) and material of the main stand (number of stems and basal area per hectare, mean diameter before and after thinning, etc.).

Cette recherche porte sur la traduction, en Belgique, d’une politique européenne de l’emploi – la flexicurité – par différents acteurs institutionnels. À partir d’une analyse documentaire et d’une vingtaine d’entretiens semi-directifs, nous étudierons la manière dont ces acteurs s’approprient et interprètent la flexicurité. Nous nous appuierons principalement sur les apports récents de la sociologie de l’action publique, en particulier l’approche cognitive des politiques publiques (Surel, 2000 ; Muller et Surel, 1998) et l’européanisation des politiques d’emploi (Palier et Surel, 2007 ; 2010). Nous montrerons que cette appropriation a donné lieu, en Belgique, à une transformation du sens conféré à la sécurité, dorénavant assimilée à de la flexibilité. [less ▲]

Ces dernières années, les institutions Européennes ont joué un rôle clé dans la régulation et l’orientation des politiques publiques pour l’emploi des États-membres (Amparo-Serrano et Martin-Martin, 2012). Dans ce cadre, la flexicurité s’est imposée comme une référence des politiques en matière de droit du travail, d’emploi, de sécurité sociale et de formation professionnelle (Conter et Orianne, 2011). En Belgique, cette exigence d’allier flexibilité et sécurité sur le marché du travail a constitué le cœur de nombreux discours et programmes politiques, pour finir par s’estomper progressivement, à la suite de crises financières et économiques l’ayant fortement éprouvé. Ce « concept » a-t-il pour autant effectivement disparu ? À partir d’une étude qualitative basée sur des entretiens semi-directifs menés auprès d’acteurs institutionnels – experts et analystes du marché du travail – nous nous sommes rendu compte que si la sémantique n’est plus, les principes de flexicurité sont, quant à eux, toujours présents dans le discours des individus. De plus, ces principes semblent détenir une portée normative de taille quant à la redéfinition de l’articulation des temporalités sociales : d’une sécurité de l’emploi, nous serions en train d’effectuer un glissement vers une sécurité en emploi de l’individu. La rhétorique n’est pas innocente : désormais, ce n’est plus tant l’individu qu’il s’agit de protéger (droit du travail, etc.) mais bien les transitions – multiples et sinueuses – opérées par ce dernier. Pour y parvenir, l’État le responsabilise : il doit désormais être capable de se prendre en mains : « c’est le passage d’un ‘État qui protège’ à un ‘État qui rend capable’ » (Vrancken, 2008).
