Purpose of the research A growing body of literature argues that management control is essential in promoting corporate sustainability (Epstein and Roy, 2001; Crittenden et al., 2011). Furthermore, the conventional accounting and control literature has identified sustainability and control as an important emerging theme (Berry et al., 2009). Nevertheless, except a series of conceptual (and often prescriptive) papers, few papers have proposed to empirically explore management control practices for sustainability. This explains partly the scepticism that has been raised about the existence of these management controls in the context of sustainability and especially about their role in promoting sustainability within the organizations (Deegan, 2002; Norris and O’Dwyer, 2004; Durden, 2008). Based on these observations, this paper aims at exploring sustainability management control practices in large European firms. It investigates the extent to which large companies have developed a package of formal and informal management control mechanisms in order to steer their organization towards corporate sustainability and, based on this empirical observations, it theorizes on typical sustainability control patterns. Principal results All of the researched companies deploy sustainability management control. There are, however, notable differences with regard to the complexity of the underlying systems and tools – from basic to advanced ones. The paper also identifies two distinct approaches in management control for sustainability. Whereas some companies seem to focus on formal approaches of management control, others concentrate on informal management control. A mixture of both was not observed in the sample companies. Major conclusions The insights and recommendations provided in this paper help organizations in translating their aspirations into their organization (Epstein and Wisner, 2005). The results also highlight the need for research to better understand the situations in which formal and informal management control for sustainability yields the results anticipated. [less ▲]

Jamoulle& M.Roland, describes the protection of patients from diagnostic tests, interventions and treatments that offer no benefit for overall morbidity or mortality for the individual, and may cause physical or psychological harm. The P4 concept pulls together all reflexive moves on the problems resulting from an excess of medical care, such as overscreening, overinvestigation, overprescription, and overtreatment. Since the first workshop in Wonca Basel 2009, the P4 concept has spread throughout the world, and has provoked an intense exchange of ideas. The speakers gathered here from around the world intend to show how front line family physicians could analyze, understand, appropriate and use the P4 concept to examine, analyze and modify their practice. The audience will be stimulated to share their concern about the limits of medicine exchange critical comments on the concept of P4. At the end of the workshop attendees will be able to able to use and apply Quaternary prevention to improve both the health of individual patients and public policy.

Functional traits, well-defined characteristics of organisms that influence or coordinate with ecological performance, promise that one may predict vital rates, such as survival and growth, by measuring a few aspects of anatomy and physiology. Functional traits have been shown to correlate significantly, though weakly, with the relative growth rate (RGR) of trees in five Neotropical forests. Here, we estimated size-standardized height RGR for 26344 saplings of 240 species from 23 sites around the world using nonlinear models of growth. We then predicted the contribution of three functional traits (specific leaf area, wood density and seed mass) to individual RGR with a hierarchical Bayesian model. The three functional traits, alone and in combination, explained a relatively small amount of variance in RGR, with variation among continents and between temperate and tropical regions. We echo the calls for researchers to shift toward the measurement of 'hard' functional traits, with clear linkages to realized vital rates, rather than 'soft' functional traits, which are easier to measure but may only indicate the theoretical maxima of vital rates. Doing so would advance ecology onto a more solidly functional foundation. [less ▲]

Parallèlement aux multiples commentaires cinéphiliques que le générique suscite depuis plusieurs années, les travaux récents qui lui sont consacrés l’envisagent comme un objet d’étude esthétique, narratologique ou sémiologique à part entière. Selon ces études, le générique est un objet fragmentaire (placé majoritairement à partir des années 1960 « sur » les images du début ou de la fin d’un film) voire autonome (on connaît les auteurs spécialisés en réalisation de génériques), marginal aussi (rarement au centre de l’œuvre ; le « générique-préface » de de Mourgues), frontalier encore (dans et hors du film, ou plutôt : à son orée), qui fait office d’ouverture ou de clôture hybride du film. Appartenant à la fois à l’univers de la fiction et à « un autre espace-temps, réel, celui de la production » (Moinereau), le générique de début plus particulièrement sert à « enclencher la diégèse » (de Mourgues) mais aussi à lui résister. « [S]orte de zone franche entre le monde de la réalité et celui de la fiction » (Metz), il est une passerelle, une aide au passage, au basculement dans la fiction. En tant que point pivot bâtard, le générique de début – et non pas « du début », appellation qui sous-entendrait l’appartenance exclusive à un seul lieu –, joue en effet sur deux registres. D’une part il affiche la ou les paternités bien réelles de l’œuvre (jusqu’au début des années 1910 il ne satisfait bien souvent qu’à cette seule obligation légale) et leur rend hommage (graphismes et durées différenciées), ou, dans ses versions les plus sophistiquées, offre au cinéphile (auto-)références et private jokes qui établissent entre le spectateur et l’auteur réel une complicité néanmoins non fatale pour le récit de fiction. D’autre part il aide le spectateur à s’abandonner à l’illusion de la fiction qui doit « mentir sur ses conditions de production » (Comolli) et dont le générique est pourtant le premier symptôme. En somme, le générique de début n’est donc pas seulement hybride par son lieu, mais aussi en raison de sa fonction quasi paradoxale : il établit avec le spectateur un lien a priori adiégétique dont la fonction première est précisément de faciliter son entrée dans la diégèse. Compte tenu de l’intérêt particulier que ces études accordent à la nature hybride du générique, il n’est pas étonnant que les travaux auxquels nous nous référons ici concernent exclusivement des films de fiction. Car, à l’inverse, dans le cas du cinéma documentaire, l’ambivalence inhérente à ce « commutateur de diégèse » (Gardies) est, en principe, inexistante étant donné que le générique d’un film non-fictionnel renvoie le spectateur à un univers « uniquement » réel, commun à l’ensemble du discours filmique. Dans cette perspective, il ne sert donc a priori qu’à inaugurer un contrat spectatoriel ou à poser les fondements d’une convention de lecture qui s’épanouira et développera sa pleine puissance dans le film (installation du principal médiateur, authentification de l’énonciateur, etc.). En documentaire, pas de conflit donc entre un espace-temps « adiégétique » et le film, entre la marge et le texte, car tous deux convoquent des éléments appartenant in fine au même registre, celui du réel. C’est en substance ce que suggère l’approche sémio-pragmatique du documentaire en envisageant le générique de début comme le lieu dans lequel un « je-origine réel » (Odin), par le biais de médiations institutionnelles ou non, prend ses quartiers dans le texte, ouvrant ainsi la voie à une « lecture documentarisante » incontestée dans la suite du film. Les paradigmes trop rapidement évoqués ici révèlent leurs limites dès lors qu’on les confronte à quelques sous-genres particulièrement pratiqués et populaires aujourd’hui tels que le faux documentaire, le docufiction, le mockumentary et le programme de télé-réalité. Se jouant précisément d’un contrat de lecture unilatéral et libre de tout malentendu, ces sous-genres documentaires brouillent la binarité posée par l’approche sémio-pragmatique (« documentarisant » vs « fictionalisant »). Notre analyse de quelques génériques, prégénériques et séquences d’annonce de faux documentaires, de mockumentaries et d’émissions de télé-réalité nous amène à redéfinir le contrat de lecture et les conventions qui y sont liées, propres au cinéma et à la télévision de non-fiction. Ces génériques ne contribuent pas à l’identification par le spectateur d’un énonciateur considéré comme réel (par jeu ou par conviction), mais établissent un nouvel accord tacite et flou entre un auteur reconnu comme fictif (ou ses avatars particulièrement nombreux dans le cas du mockumentary et de la télé-réalité) et le spectateur. Ce nouvel accord vise en réalité à produire l’adhésion forcée d’un spectateur qui pourtant sait qu’il n’est pas dupe, ou croit le savoir. Dans ce sens, le générique apparaît alors comme un lieu crucial pour toute analyse critique du discours non fictionnel : un lieu qui conteste l’authenticité de l’énonciateur et qui nie le crédit accordé au médiateur documentaire, pour offrir au public l’illusion de sa lucidité et le pousser ensuite vers une adhésion sans réserve à un jeu de réel. En somme, une étape indispensable à la constitution d’une crédulité paradoxale du spectateur. [less ▲]

The current study is focused on the iron ores granulation process in a laboratory-scale batch drum granulator using water as a binder, and on the investigation of the influence of raw material properties (morphology and wettability of the primary particles) on its kinetics. Nowadays processing of iron ores often requires a modification of particle size by means of granulation in order to improve further processability. A comparison of the granulation behaviour of three types of iron ores (magnetite, hematite and goethite) has been carried out. The wettability of the powders has been characterised by contact angle measurement. The results confirm the hydrophobic and hydrophilic characters of magnetite and goethite respectively. The granulation kinetics (evolution of particle size distribution as a function of time) of each type of iron ores was measured. [less ▲]

The Niger’s rural population represents 80 percent of the total population. This very high percentage creates an important pressure over the environment because of the high density of population. Indeed, the agricultural favorable area is equivalent to a third of the total area of Niger. This area is located in the South of Niger over a strip 300 kilometers of broad. Furthermore, the rural population is subjected to the temporal and structural disruptions. The temporal shocks are defined by the “natural” disruptions such as the hydrometeorological disruption, etc. The structural disruptions are caused by the chronicle difficulties (low income, etc.). The capacity to struggle against the disruptions is defined by the resilience (Lhomme et al., 2010). The resilience is illustrated and assessed by the different coping strategies practiced by the Niger’s rural population. The target of the paper is to demonstrate the state of food insecurity and the coping strategies developed in the departments of Niger. The state of food insecurity and the coping strategy index are calculated as from the data of an annual survey realized by the Early Alert System (EAS) and the Statistical National Institute of Niger (INS). This survey investigates around 10.000 households in December 2009 and April 2010. The sample is extrapolated to estimate the number of people suffering from food insecurity per department. The paper illustrates the state of food insecurity of each department and coping strategy index of the departments. The results will demonstrate the differences between departments. The answers of the paper at the following question: Which are the most vulnerable departments and what is the situation of the coping strategies index in each department? This paper creates also a typology bringing together the same departments in comparison with the coping strategies and the state of food insecurity. [less ▲]

For conservation biology and sustainable management, the natural character of tropical forest is a crucial issue. Its assessment is usually based on ecological proxies such as forest composition and structure. However the estimation made on this basis only considers short term processes at a local scale. In contrast the long term processes are appraised by palaeoecological proxies (such as pollen) at a regional scale. So as to assess the degree of naturalness of tropical ecosystems in a conservation perspective it is important to combine a long temporal scale as well as a fine resolution spatial scale. Such approaches using palaeoecological proxies have been recently tested in temperate Europe but little in tropical ecosystems. Nonetheless the long term preservation of the palaeoecological material and its broad presence in the environment are necessary conditions to fulfill. In this perspective soil charcoal appears to meet these requirements. In this paper we aimed at assessing the naturalness of tropical forest using soil charcoal from southeastern Cameroon. Fieldwork involving as well archaeology as botany was undertaken at 53 sites. We quantified charcoal in soil samples by layers of 10 cm taken from pits located in the center of plots of botanical inventory. Spatial projections were performed using statistics together with multivariate analyses. Radiocarbon dating allowed interpreting the temporal framework. Results showed the ubiquitous presence of charcoal at each site. Main charcoal peaks were interpreted as fields (slash-and-burn agriculture) in the vicinity of ancient villages. These practices shaped the forest over time which cannot be considered as natural anymore. This underlines the potential input of the use of palaeoecological material in conservation biology and sustainable management issues. Charcoal fragments are under taxonomical identification and may provide new insights on the long term history of forest composition. [less ▲]

Why species do not occur everywhere? The concept of ecological niche is central to understand relationships among biotic/abiotic factors and species distribution. Gradients of environmental stress associated to interspecific interactions generate testable patterns of specie’s response curves. Distribution of response curves have been seldom tested along toxicity gradient, in contrast to resource gradients. On Katangan copper hills (south R.D.C.), natural copper and cobalt concentrations span a large range: 2 - 1000 mg kg-1 for cobalt and 30 - 10 000 mg kg-1 for copper. In this study, we evaluate three hypotheses related to niche distributions and shapes along metal toxic gradients: (1) Species optima are uniformly distributed over copper-cobalt gradient. (2) Realized niche width varies in relation to the niche optimum along copper and cobalt gradient. (3) Absolute values of skewness coefficient are higher when plant species optima are in the extremes of cobalt gradient with a niche tails toward mesic conditions. Realized niches of 80 taxa were modeled with general additive models (GAM) using presence/absence data in 172 1m² plots. Niche optima, niche widths and skewness coefficients were estimated from species response curves. The three hypotheses were globally validated. Three groups of species were distinguished according to their optima position along metal gradient with packed optima on intermediate concentrations suggesting higher interspecific competition in low metal concentrations. Niche width increased with metal concentrations. Highest metal tolerant plant species had broader niches. Skewness coefficient was inversely related to niche optima positions. Our study demonstrates that species distribution pattern on toxicity gradient presents similarities with resource gradient. Broad realized amplitude of species adapted to high levels of copper cobalt concentrations suggests that fundamental niche of specialist metallophytes may be larger than expected. This should be further tested in controlled conditions in association to competition tests. [less ▲]

Studies conducted in the Congo Basin forests concluded that soil parameters and large disturbances induced by human activities since 3000–2000 BP could be the main driver for the persistence of long lived light-demanding tall tree species. Today most of the timber species belong to this group, among them Pericopsis elata (Fabaceae). Like many other light-demanding trees, this species suffers from important regeneration problems. While the conditions for its establishment must have been met in the past, they obviously have become unfavourable. Because of ongoing logging activities and a natural decline of its populations, this species is recorded in both the IUCN Red List and the CITES Appendix II listings. Our goal was to investigate the roles of both pedological and anthropogenic factors in the persistence of forest patches characterized by this clustered species. Soil surveys, botanical inventories and anthracological excavations were conducted in three different forest sites located in south-eastern Cameroon. P. elata patches (3.3-14.7 ha) were studied and compared to their close surroundings. No statistical differences were observed between the results of botanical inventories conducted inside and outside the patches (Morisita-Horn indices from 0.69-0.77). Soils only differed in Fe content, but otherwise no significant differences could be observed. Charcoal is widespread and abundant in study sites, mostly inside the patches. Charcoal radiocarbon dating (2,150-195 BP) was consistent with decoration techniques of archaeological materials that we discovered. The average age of P. elata individuals coincides with fire events that occurred in a region where fires rarely occur naturally. We present evidence of past anthropogenic disturbances (human settlement, slash-and-burn cultivation) in the Congolese mixed moist semi-evergreen forest in south-eastern Cameroon. We discuss the potential influence of our findings on the management of light-demanding tall trees populations in a context of logging activities. [less ▲]

Pourtant classique en ethnographie et en analyse par théorisation ancrée, la pratique du journal de bord est méconnue de nombre de doctorants et de chercheurs en sciences humaines et sociales. Or, ses vertus en font un adjuvant de premier ordre pour garantir des recherches de qualité, des publications régulières, des thèses de doctorat finies dans les temps et des carrières enrichissantes. Au niveau scientifique, (1) le journal de bord permet de consigner les notes de terrain, y compris sur ce qui n'est pas enregistrable. (2) Il organise la mémoire de la recherche et en assure la documentation ultérieure. Il soutient dès lors la « traçabilité » et la validation des analyses développées. (3) Il catalyse également la réflexivité et favorise la régularité de l'analyse, qui contribue au développement d'analyses fines et plus élaborées. (4) Une version rédigée du travail en cours est toujours disponible (dans une forme temporaire, certes) pour le comité d'accompagnement ou pour répondre à un appel à communication. Au niveau logistique, (5) la tenue du journal de bord permet en outre de désamorcer les blocages de l'écriture, de lutter contre l'angoisse de la page blanche, voire contre l'ennui, facteurs d'abandon en fin de recherche doctorale. Pour chacune de ces caractéristiques, un exemple issu des recherches ou des enseignements de l'auteur éclaire l'apport du journal de bord, mais aussi ses limites voire les pièges à éviter. [less ▲]

Nucleic acids are flexible molecules: their dynamical properties play an essential role in molecular recognition and self-assembly. In the biological environment, because of mechanical forces acting at the molecular level, DNA is transiently deformed, cut and resealed, damaged and repaired, and the strands pulled apart and then re-annealed. These unique features make short DNA oligonucleotides promising building blocks in the development of “bottom-up” nano-devices and molecular logic machines. Single molecule manipulation techniques (Atomic Force Microscopy/ Optical Tweezers) allow detailed investigation of nucleic acids response to the application of controlled mechanical stress. Interpretations of these data in terms of molecular structural changes and dynamical properties call for a collaborative effort between experiments and theoretical/computational modeling. We have theoretically investigated the dynamical properties a DNA dodecamer and its complex with two different binders (Hoechst 33258 and Ethidium cation) by performing fully atomistic classical Molecular Dynamics (MD) simulations. We focused on the modeling of the so-called overstretching transition occurring when double stranded DNA is subjected to a shear stress until separation of the two strands occurs. The results of our analysis reveal the molecular details of the overstretching dynamics and point out the effects of the binders on the structure and the dynamics of the oligonucleotide under stress. The minor groove binder Hoechst 33258 acts as a zip between the two strands enhancing the lifetime of some base-pairs during the pulling experiment while ethidium cation, which is an intercalator, facilitates the separation of the double helix at high elongations. The understanding of the interactions between the binders and the helix at the molecular level gives insights into the unbinding pathways probed by Single Molecule Force Spectroscopy (SMFS).

PSII antenna size heterogeneity has been extensively studied in the past. Based on in vivo DCMU fluorescence rise kinetics, at least two types of photosystems were described. They differ by their apparent antenna size and connectivity (this last term refers to the transfer of absorbed energy from a closed PSII unit to an open neighboring unit). In this study, we analysed PSII heterogeneity in Chlamydomonas reinhardtii using non-linear linear regression fitting on in vivo DCMU fluorescence rise kinetics, with a focus on changes in PSII heterogeneity associated with state transitions. We found that PSIIα possesses a high degree of connectivity and an antenna about 3 times larger than PSIIβ, as described previously. In contrast with most earlier studies, we found some connectivity for PSIIβ (although it was highly variable). This is in agreement with recent models based on biochemical and structural analysis of PSII after gel filtration separation which describe PSII mega-, super- and core- complexes in Chlamydomonas. According to these studies, the smallest unit of PSII in vivo would be a dimer of two core complexes hence still allowing connectivity. We also showed that strain and medium dependent variations in the half-time of the fluorescence rise, generally taken as an indicator of the average cross-section of PSII, can be explained by variations in the proportions of PSIIα and PSIIβ. When analyzing the state transition process, we showed for the first time in vivo that it induces an inter-conversion of PSIIα and PSIIβ. These findings are discussed with respect to the latest insights on the remodeling of the pigment-protein PSII architecture during this process. [less ▲]

The risk analysis framework has been the dominant theoretical framework used to address the uncertainty of a potential hazard bypassing the system's safeguards and protection. In essence, this involves the evaluation of the probability and the magnitude of the consequences of the undesired events that can transform the hazard into actual damage. Despite the technical premises, the importance of integrating social aspects into the analysis is now recognized by an increasing number or risk analysis models. Another way to deal with potential consequences of hazards is to analyze the vulnerability of the system considered. This paradigm overcomes the shortcomings of risk analysis in situations when the knowledge about the probabilities and the outcomes is incomplete or insufficient On the one hand, studies in the literature show that socio-economic factors are often integrated in a participative way in vulnerability analysis models especially in the natural hazards research field. On the other hand, it seems that such considerations are rarely integrated in the models aiming at evaluating the vulnerability to an industrial hazard. What can we learn from the analysis of models addressing vulnerability to natural hazards in terms of the participatory integration of social factors? What could be the reasons to apply such participation tools in order to assess the vulnerability to industrial hazards? These are the questions we address in this contribution. To do so, we realized a systematic literature review from scientific journal papers on vulnerability analysis published in the last two decades. From this review, three main arguments can be found arguing for the use of participation for vulnerability analysis. Indeed, participation allows (1) context-based assessments, that may (2) foster the development of adaptative capacities (3) both for short and long-term. Based on those arguments, we identifiy possible paths to foster participation for context-based industrial vulnerability analysis. [less ▲]

This paper is based on Derrida’s deconstruction of significance, and focuses on how media-based discourses organize the audience in a public space. In audience studies, the text/reader relationship remains a difficult point because it remains unclear how to account for the fact that the media structure perception, although they do not determine it. To solve this contradiction, we need to link together facts and possibilities (empirical and transcendental levels) in a way that keeps alive this relationship between a text and a reader. This is what Jacques Derrida’s work makes possible. We’ll mainly use his concepts of “address” and “destination”. The “address” might be considered as an attempt to translate the linguistic “enunciation” into phenomenological terms: the address modifies reference and thus inscribes the reader in a “world”. As for the “destination”, it refers to a model where communication is indeterminate (“incalculable”). This model gives readers the opportunity to create previously unseen kinds of worlds, or communities of “common sense”. In this way, this model is political. Our analysis allows us to account for both representations of the world and places given to readers in this world, so that we can describe, with this “sharing of the sensory”, mediated experience as political.

Cell-based tissue engineering constructs are an interesting expansion of the surgeon’s toolkit in treating long bone defects. However, the outcome of interventions with these constructs suffers from high variability barring their regular appearance in the clinic, in no small part due to the inter-patient variability in cell behaviour. In the paradigm of ‘developmental engineering’ a solution to this problem is envisioned by mimicking robust developmental processes in combination with a rigorous analysis thereof through the construction of computational models. From our knowledge of developmental biology we can form a computational model to facilitate understanding of how growth factors and transcription factors influence cell fate decisions in the growth plate and consequently answer the question whether – and how – they can boost bone healing. The model presented in this study includes 46 factors and 146 interactions between them. The dynamics of the system were simulated in a simplified manner that differentiates between slow and fast interactions. Through a Monte Carlo approach the importance of each factor in the stability of chondrocytic phenotypes (proliferating, hypertrophic) is assessed. The hypertrophic state was found to be more stable than that of the proliferating chondrocyte. This higher stability in random initial conditions seems to be conferred by faster reactions that favor the hypertrophic phenotype. Overall, the model allows the importance of several important factors in the fate decision of chondrocytes to be quantitatively assessed and can make suggestions as to how an in vitro bone forming process could be steered.

A one year old girl, born to consanguineous parents, presented with unexplained liver disease. Liver biopsies revealed respiratory chain complex I and IV deficiencies. Progressive liver failure at 19 months led to liver transplantation. One year later, anemia and thrombocytopenia occurred due to hypersplenism. Histopathological analyses of partial splenectomy showed the presence of Gaucher cells, and Gaucher disease was confirmed by enzyme and genetic analyses. Respiratory chain deficiency was considered as a possible artifact due to liver failure and cirrhosis. She was treated by ERT. Clinical follow-up showed developmental delay, strabism, nystagmus and external ophthalmoplegia. A mitochondrial disorder was considered again, and molecular analysis revealed a mtDNA depletion syndrome due to homozygous MPV17 mutation. In the meantime, a young sister presented with acute abdominal pain, pancytopenia and major hepatosplenomegaly. ERT for Gaucher disease allowed visceral normalization, without any developmental delay or neurological symptom. She was unaffected by the mtDNA depletion syndrome. Unfortunately, a third sister systematically screened, was affected by both conditions. Despite ERT, she presents chronic moderate liver dysfunction and mild hepatomegaly. Aged 3 years, she has marked developmental delay and ophthalmoplegia. Metabolic investigations showed normal blood lactate, in basal condition as well as following an oral glucose load [less ▲]

Documentée par des milliers de papyrus, parchemins, ostraca, tablettes de bois ou cirées, – restes de livres ou de documents dont les plus anciens remontent au IIe siècle de notre ère –, la christianisation de l’Égypte a longtemps été perçue comme un phénomène ayant entraîné la disparition de la culture profane de tradition hellénique (paideia). Il faut cependant nuancer ce propos : nombre d’échanges, d’emprunts entre les deux types de cultures ont existé. La découverte, à côté de quelques papyrus, de 37 ostraca à contenu littéraire profane dans les ruines de monastères égyptiens, tous de la région thébaine, et datant de la fin du Ve siècle au milieu du VIIIe siècle, constitue un petit ensemble de témoins de ce phénomène. Nous fondant sur l'analyse de la forme, de la mise en page et du contenu de ceux-ci, nous montrerons par quels biais la paideia hellénique s'est introduite dans les monastères, milieux chrétiens par excellence.

Depuis 1997, l’espace socio-public camerounais « devient média » (Blondeau, 2007) de plus en plus. Dans ce processus, la politique ne fait pas exception. Au contraire, les partis et leurs leaders investissent l’Internet, le territorialisent et en utilisent les outils : sites web et blogs, forums, facebook, twitter, myspace, etc. Cela apparaît techno-politiquement innovant dans un contexte certes marqué par le multipartisme, la libéralisation de l’espace sociopolitique et l’avènement des NTIC, mais qui présente aussi des déficits. Politiquement, on note une opposition en panne, des élections contestées et une faible culture de participation politique. (Ahmadou, 2006; Mack-Tit, 2007; Kokoroko, 2009). Au plan sociotechnique et économique, le taux de pénétration de l’Internet (4%) et le pouvoir d’achat de 70% de la population restent faibles. Cela limite l’accès au Net (Bâ, 2003) mais n’empêche pas son usage et sa représentation politiques. Nous avons étudié cet usage et cette représentation au niveau macro-politique en nous limitant aux acteurs institutionnels. Nous avons alors remarqué que leur cyberprésence c’est-à-dire la façon dont ils s’approprient l’espace numérique tend à reproduire leurs rapports de force dans le champ politique classique (Ovadia, 2011). Les usages politiques qu’ils y développent traduisent davantage la diffusion de l’information que l’interactivité et la mobilisation (Greffet et Wojcik, 2008). Dans ce contexte, les enjeux démocratiques de net-politique varient selon le caractère « opposant » ou « au pouvoir » des acteurs (Greffet, 2011). Si pour le parti au pouvoir, il s’agit de dominer tous les espaces d’expression politique, pour les opposants, le but est de trouver une visibilité nationale et de se faire entendre à l’international. Pour mener ce travail, nous avons examiné trois points : la cyberprésence des acteurs institutionnels, le contenu de leurs sites web et blogs et celui de leurs pages facebook. Nous situant dans la perspective de la communication médiatisée par ordinateur (Yanoshevsky, 2010), nous avons alors utilisé les indicateurs que Bastien et Greffet (2009) et Béché (2011) ont utilisés dans leurs travaux sur la net-campagne.

In the Fifth Logical Investigation, after a series of objections to Brentano’s thesis that presentations constitute the most basic type of mental acts, Husserl offers the alternative of a fundamental distinction between objectifying and non-objectifying mental acts. Objectifying acts include the first two Brentanian classes: presentations and judgments. Thus the class of emotions is singled out as the typical model for non-objectifying acts. However, Husserl changes his mind on this issue later on. We find a new and rather surprising theory of emotions in his Ideas I of 1913. In the §117 for instance, Husserl states clearly that all acts, emotions included, are objectifying because they all constitute objects. The only difference between emotions and cognitions is that emotions constitute values as their objects. Since all acts are objectifying, the difference is now between kinds of objects rather than kinds of acts. It seems though that the role values play in our mental life is more complicated. Not only are they dependent objects constructed from objects of simple presentations or judgments, but they are also the sort of objects that can motivate other acts. So, while emotions are in Husserl always dependent on cognitions, since wanting something necessarily supposes, as in Brentano, a previous presentation of that thing, certain emotions can also play a foundational role for cognitions. Hence the question addressed in this paper: is the relation between emotions and cognitions a symmetrical one since both can play the role of foundational act for the other? And if this is the case what is the specificity of emotions as mental acts and how can they be distinguished from cognitions? [less ▲]

Polysaccharides, proteins, lipids and other biopolymers are the main components of food and pharmaceutical mixtures and may influence interactions at interfaces and thus fouling and cleaning. In this study, quartz particles (10 to 30µm) were used as a model soil for examining the effect of dissolved proteins on the cleanability of substrates after soiling and drying. Glass and stainless steel pretreated by UV-Ozone (StSteel-UVO) were used as model hydrophilic substrates, while hydrophobic substrates were represented by stainless steel cleaned with ethanol (StSteel-Eth) and polystyrene. BSA and β-LGB were used as proteins. The quartz suspensions used for soiling (150g/L) were prepared in pure water and in a solution of each protein (8g/l). After soiling and drying, the cleanability was evaluated using a radial-flow cell, with pure water as the cleaning fluid. When soiling was made with a quartz suspension in pure water, the soil adherence increased with substrate hydrophilicity. This may be explained by better droplet spreading and increase of the capillary forces created upon drying. The presence of proteins in the suspension used for soiling hydrophilic substrates (Glass and StSteel-UVO), decreased the adherence of quartz particles. Its effect was less marked and tended to be opposite for less hydrophilic substrates (StSteel-Eth, Polystyrene). The comparison of different substrates and two proteins showed that the adherence cannot be explained by a simple relation with the contact angle. Other factors may be the solution surface tension itself and the protein behavior at the interfaces created by drying and by rehydratation during cleaning. When considering the influence of substrate on soiling, it must be kept in mind that high surface energy solids (metals, oxides) are readily contaminated in contact with air and lose their hydrophilicity. Amazingly this may improve the substrate behavior regarding cleanability with respect to particulate soil. [less ▲]

Un cas d'étude : René del Mel ou l'exemple d'une fidélité aux membres de la famille Lorraine-Bavière. René Del Mel (ca. 1554-ca. 1598) voit le jour à Malines, dans un milieu proche de la famille ducale de Lorraine. Son parcours incarne sans nul doute à la fin du XVIe siècle l’un des derniers exemples de la transhumance européenne des franco-flamands. Le compositeur entre successivement au service de la cour de Portugal et d’une série de centres dans la périphérie de Rome et à Venise. Il devient ensuite le maître de chapelle d’Ernest de Bavière à Liège, effectue un séjour de deux ans dans les Pays-Bas méridionaux puis revient en Italie. René del Mel ne transgresse pas à la coutume de se placer sous les faveurs d’un haut personnage. Les textes dédicatoires de ses recueils conservés révèlent la mise à profit par le compositeur de l’espace de liberté qui subsiste à l’intérieur d’un tel cadre apologétique. De 1588 à 1596, par d’incessants dons de recueils, en dépit de nominations à d’éventuels postes ou d’octroi de gratification quelconque, del Mel entretient un lien privilégié avec la Maison de Lorraine et, par mariage, avec celle de Bavière. Les moyens qu’il met en œuvre tendent à un perpétuel affermissement de ce lien ancien et rendent manifeste sa volonté de conserver une allégeance à la cour de Lorraine. Par extension, ils jettent un précieux éclairage sur les liens à tisser entre les deux Maisons. [less ▲]

Il n’est pas rare de voir des étudiants répondre de façon inappropriée à une épreuve d’évaluation comportant des items à réponses choisies. Par exemple, certains individus peuvent tricher alors que d’autres peuvent tenter de se sous-classer intentionnellement à un examen. Plusieurs approches ont été développées pour faire la détection de ce type d’étudiants. À ce jour, l’approche la plus prometteuse est l’utilisation d’indice de détection de type person‐fit (Meijer et Sijtsma, 2001). L’indice de détection lz (Drasgow, Levine et Williams, 1985) est fort probablement le plus utilisé et le plus connu d’entre tous. Malheureusement, cet indice est fortement affecté par le fait que l’habileté des étudiants est estimée et non pas réelle ; ce qui peut biaiser son calcul (Molenaar et Hoijtink, 1990). Pour pallier ce problème, Snijders (2001) a proposé une correction qui permet de diminuer considérablement le biais associé à la moyenne et à la variance de l’indice lz. Dans le cadre de notre projet doctoral, nous nous inspirerons de la suggestion de Snijders (2001) pour corriger deux autres indices de détection de patrons de réponses inappropriés : l’infit mean square (u) et l’outfit mean square (w). À cette fin, nous utiliserons une approche monte carliste afin d’investiguer plus en détails l’erreur de type 1 et la puissance de ces autres indices. Nos résultats préliminaires, que nous présenterons lors de cette communication, montrent que ces autres indices corrigés semblent eux aussi plus efficaces que leur version traditionnelle sans correction.

The recent revelations about Australia’s colonial past, particularly the dispossession and the institutionalized maltreatment of the Aboriginal populations, have provoked an ontological and epistemological malaise affecting notably the sense of historical and cultural legitimacy previously enjoyed by settler Australians. This was a consequence of the work performed by progressive historians who endeavoured to lay bare the brutal foundations of the nation, thus confronting the settlers’ descendants with an array of harrowing truths difficult to reconcile with any foundational myth of pioneering heroism. This context of angst and guilt has given rise to a new literary trend, known as the “Sorry Novels”, which is informed by the wish to come to grips with the trauma of colonization by acknowledging the harm done to the Aborigines. In tackling the vexed issues of dispossession and frontier violence, Kate Grenville’s The Secret River (2005) ostensibly belongs to this well-intentioned literary trend. However, as one examines the novel carefully, one notices that vestiges of a mythologized past presently emerge. From mythologies of convictivism and hardship to pioneerism and ownership, the representation of the colonial past abounds with continuing references to a range of national myths that stand in marked contrast with the author’s avowed keenness to inscribe her novel within the framework of a genuine reconciliation. It is, therefore, my intention in this paper to conduct a close reading of The Secret River with a view to unveiling the unsettling significance of some representational strategies – which might at first glance appear as insignificant – and thus emphasising the ambivalence which characterises Grenville’s discourse about the colonial trauma.

As defined by ICH [1] and FDA, Quality by Design (QbD) stands for “a systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management”. A risk–based QbD–compliant approach is proposed for the robust development of analytical methods. This methodology based on Design of Experiments (DoE) to study the experimental domain models the retention times at the beginning, the apex and the end of each peak corresponding to the compounds of a mixture and uses the separation criterion (S) rather than the resolution (RS) as a Critical Quality Attribute. Stepwise multiple linear regressions are used to create the models. The estimated error is propagated from the modelled responses to the separation criterion (S) using Monte Carlo simulations in order to estimate the predictive distribution of the separation criterion (S) over the whole experimental domain. This allows finding ranges of operating conditions that will guarantee a satisfactory quality of the method in its future use. These ranges define the Design Space (DS) of the method. In chromatographic terms, the chromatograms processed at operating conditions within the DS will assuredly show high quality, with well separated peaks and short run time, for instance. This Design Space can thus be defined as the subspace, necessarily encompassed in the experimental domain (i.e. the knowledge space), within which the probability for the criterion to be higher than an advisedly selected threshold is higher than a minimum quality level. Precisely, the DS is defined as “the multidimensional combination and interaction of input variables (e.g., material attributes) and process parameters that have been demonstrated to provide assurance of quality” [1]. Therefore, this DS defines a region of operating conditions that provide prediction of assurance of quality rather than only quality as obtained with traditional mean response surface optimisation strategies. For instance, in the liquid chromatography there is a great difference in e.g. predicting a resolution (RS) higher than 1.5 vs. predicting that the probability for RS to be higher than 1.5 (i.e. P(RS> 1.5)) is high. The presentation of this global methodology will be illustrated for the robust optimisation and DS definition of several liquid chromatographic methods dedicated to the separation of different mixtures: pharmaceutical formulations, API and impurities/degradation products, plant extracts, separation of enantiomers, … [less ▲]

Les microalgues sont des micro-organismes photosynthétiques dont la culture commerciale en masse est pratiquée depuis les années '60. Les rendements en biomasse de la culture de microalgues sont supérieurs à ceux de cultures traditionnelles, et elle peut s'effectuer sur des terrains impropres à l'agriculture traditionnelle. Les perspectives d'utilisation de la biomasse microalgale pour la production de biocarburants ont suscité d'importants efforts de recherche au cours des années récentes. Les recherches en cours visent à améliorer les souches d'algues utilisables ainsi que différents aspects des procédés de production, de traitement et d'extraction de la biomasse algale afin d'aboutir à moyen terme à un procédé durable et économiquement viable.

Nous proposons une relecture à deux voix – historico-littéraire – des pièces du dossier épistolaire de Francfort attribué à Alcuin. Nous envisagerons les stratégies littéraires et oratoires mises en œuvres par Alcuin au nom des évêques francs, d’une part, et de Charlemagne, de l’autre, pour tenter de ramener l’épiscopat espagnol dans le giron romain. Nous tenterons d’affiner notre lecture des positions de chacun, perçues à travers le prisme des mots du diacre anglo-saxon. La confrontation de ces lettres synodales à celles qui ont été envoyées par les évêques espagnols, emmenés par l’archevêque Élipand de Tolède, devrait nous permettre de nourrir une réflexion sur le rôle, l’importance et la puissance stylistique du genre épistolaire, hérité de l’Antiquité, dans deux foyers importants de haute culture de l’époque – la péninsule ibérique et le monde insulaire – ainsi que sur l’impact de cette querelle épistolaire dans le processus de re-développement du genre dans le cadre de la renaissance carolingienne.

The Niger economy is mainly based on the rural sector such as the agricultural and breeding activities. Indeed, 80 percent of population is rural. The agricultural financing is a necessary condition to increase the livelihood of the rural populations. The paper establishes a typology of the rural financing mode. This typology identifies the strengths and weaknesses of the financing actors (public and private). In conclusion, the real demand isn’t satisfied because the rural financing stay weak on account of the high risk and the higher costs linked with the agricultural activities. [less ▲]
