The purpose of this talk is to briefly present the logistic regression procedure to identify differential itm functioning (DIF) in psychometrics, and to illustrate the method on a practical data set about intellectual disability. DIF is an important research fi eld and many statistical methods have been developed in this framework. Logistic regression has the asset of not being based on item response models, and it can detect both uniform and nonuniform DIF. In addition, it can be applied to the comparison of more than two groups. This method is illustrated by comparing two groups of French pupils, one group of normal ability students and one group with intellectually disabled students. Raven's Colored Progressive Matrices test is assigned and DIF is investigated between the two groups. It is concluded that none of the items can be flagged as functioning differently. [less ▲]

A partir d’analyses menées dans les secteurs psycho-médico-sociaux et publiées dans Le nouvel ordre protectionnel (Parangon, 2010, à paraître), cet exposé tentera d’illustrer combien de nouveaux dispositifs d’intervention sur les personnes apparaissent aujourd’hui comme de vastes ensembles de mises à l’épreuve et d’évaluation des personnes. Tous ces dispositifs formels, ces techniques, ces objets ancrent les épreuves, les matérialisent en vue d’éprouver les qualités des personnes et de permettre un jugement. Mais les épreuves peuvent également apparaître comme « épreuves de force » destinées à aboutir à un accord sur les qualités désormais requises auprès des personnes. Toute cette réflexion s’inscrirait dans un phénomène plus vaste ; celui d’un glissement de régime d’action. A côté d’un régime de catégorisation, caractéristique des régimes occidentaux providentiels, nous assisterions à l’émergence d’un régime de déplacement au sein duquel les épreuves s’exerceraient sur base de rapports de force plutôt que de contraintes normatives. Ces épreuves se joueraient dorénavant au niveau local, sur le plan singulier. Elles s’accrocheraient aux événements et aux circonstances de la vie, mobiliseraient les récits et les subjectivités. Si notre hypothèse étayée sur cette approche issue de la sociologie pragmatique s’avérait exacte, nous assisterions alors à l’avènement d’un monde de mises à l’épreuve permanentes mais sans cesse contestées, peu solides. Un monde où les opportunités de rencontres, de situations d’échange et de transactions tendraient à se substituer au jeu de la catégorisation. Au plan du sujet, ce déplacement traduirait un glissement de l’abstrait vers le concret, de valeurs abstraites et générales (la justice, la santé, l’éducation, etc) vers des situations et des représentations plus subjectives. Autant le régime de catégorisation contribuait à créer de l’appartenance commune et tendait à engager tous les êtres que la catégorie rassemblait, autant le régime de déplacement se conjuguerait avec la diversité des comportements et des engagements momentanés.

The human-macaque interface is increasingly the focus of many researches in East and South-east Asia. The efforts target the understanding of human impacts on macaques and the risks of pathogen transmission, the mitigation of conflicts as well as the establishment of suitable management programs. Commensal relationships between humans and several species of macaques exist for centuries in some Asian locations, like in Bali (Indonesia), Japan or India. However, the frequency and the intensity of these interactions are strongly increasing over the recent decades, due to the extensive urbanization and recruitment of forestlands for cropping. We conducted a comparative study on two commensal long-tailed macaque (Macaca fascicularis) populations, one in Bangkok (Thailand) and the other in Bali (Indonesia), in order to assess the impact of anthropogenic factors (human presence and food provisioning frequency) on some eco-behavioural aspects of this macaque species living in urban landscapes. We found a consistent impact on the activity budget and the diet composition in both populations, suggesting an important role played by these anthropogenic factors for this species. Additionally, we did not find any impact of food provisioning on agonistic interactions in the two populations, contrary to previous studies in other macaque species. We suggest this surprising result could be explained by the high abundance and constant availability of human food in both sites, decreasing foraging pressures and the associated social competition. Further field studies are in progress in other populations of Macaca fascicularis in Bali in order to confirm this consistency of human impact on the behavioural ecology [less ▲]

INTRODUCTION. Premature ejaculation (PE) is a common sexual disorder. However, only few affected people consult clinicians in order to overcome this problem. Although no definitive consensus about its aetiology emerges, some mechanisms of PE are now well known. This allows more precise and efficient treatments, both at pharmacological as well as cognitive-behavioural levels. Further, studies have shown that reading didactical documents about their PE problem might be useful to men. Such approach is called “bibliotherapy”. AIM. The aim of the present study was to improve the bibliotherapy approach on the basis of up to date knowledge and techniques. The expected benefits were: (1) an efficient manual shorter than previous ones, (2) therapeutic principles easier to assimilate and (3) a method thereby made accessible to a large public which usually does not consult for this type of sexual problem. METHOD. A short bibliotherapy named Practical Guide of PE [in French] was tested among 421 PE subjects (DSM-IV diagnosis criteria). Self-reported anxiety, sexual satisfaction, ejaculatory latency time, feeling of control and distress were measured: (1) at baseline, (2) at 4-8 months and (3) at 10-14 months after reading the Practical guide of PE. A control condition was composed by 67 subjects left on a waiting-list for two months after baseline. RESULTS. Significant improvements were found for all the self-reported parameters, either at 4-8 and at 10-14 months after the bibliotherapy. The improvements were associated with an adjustment of sexual cognitions (SIQ, McCormick & Jordan). The response to treatment seemed better when the severity of PE was moderate, but did not seem related to variables such as age, educational level and personality traits (TCI-R, Cloninger; STAI Y-B, Spielberger.) CONCLUSION: Its cost/benefit ratio makes the Practical Guide an ideal first line therapeutic tool. Its large diffusion might be useful in order to improve sexual health in populations [less ▲]

For few years, carbon nanotubes (CNTs) are added to in various materials. As CNTs have high mechanical, thermal and electrical properties, it is expected to boost by adding CNTs the performances of the matrix material. Usually carbon nanotubes are used as additive to an organic matrix and in small quantities, below 1 wt%. In this work we develop composite materials with high amount of CNT, based on a carbon nanotubes network. The main type of CNT network manufactured and tested is buckypaper obtained by filtration of CNTs dispersed in a liquid solution. Other CNT networks like 3D preformed shape and CNT arrays have been also investigated. The potential improvement brought by adding CNT network to conventional materials has been evaluated using the engineering rules established for composites. Hence, the maximal achievable material properties have been estimated. Using the previously described analysis, the potential of CNT reinforced composite for different space applications have been ranked. The mechanical (mainly for CNT fibre) and thermal driven applications seem the most promising ones, especially if specific properties are considered (due to the low density of CNTs). On the basis of this evaluation and manufacturing technologies available in our consortium, experimental efforts have been put on the optimization of the CNT network mainly for improving its thermal performances. Influence of the CNTs characteristics on the macroscopic buckypaper properties has been evaluated with CNTs of different morphology (MWNT, DWNT), length and functionalization. Several processes for manufacturing the buckypaper have been tried, using different solutions for CNTs dispersion (surfactant, water or ethanol), or applying alternative method like in-situ growth of CNTs on buckypapers. Among different CNT network post-treatment also tried, thermal treatment up to 2800°C has given the greatest improvement on the specific thermal conductivity. Eventually the CNT network is infiltrated by an organic (epoxy) or inorganic (aluminium) matrix to make the composite. 3D shape CNT network gives highly reinforced composite with 30wt% of CNTs. Even if current properties of CNT reinforced composite materials are not yet competitive with reference aerospace materials, improvement potential is large and manufacturing technologies are growing.

STS scholars are increasingly engaged with science and technology practitioners, scientists, engineers and the like. The actual dynamics of these engagements differ from one project, framework or school to the next. However, to be reflexive, such engagements exercises need to deal at some point with the ambiguous ethical relationships between engager and engaged. In an attempt to disambiguate some of these interactive ties, we begin by considering the respective agendas of involved participants. To do so, we draw upon Despret’s perspectives about experiments on animals and the paradoxical relationships they give rise to. We identify the implied injunctions among STS scholars not only to "be reflexive" but also to reflect back onto practitioners their own worldviews. We then consider some of the ethical tensions, ambiguities and paradoxes between and emerging out of reflexive engagements of the self and of the other. Particularly, we explore to what extent reflexive engagements constitute ends in themselves or means to other ends. We ground this analysis in empirical evidence from an engagement study conducted in a large-scale R&D center in Flanders, Belgium. [less ▲]

Jupiter's UV aurorae have been observed extensively for the last twenty years using the Hubble Space Telescope and the infrared aurorae have been investigated using ground-based telescope observations. The two wavelength regimes complement each other; the UV is a tracer of inputs from the magnetosphere while the infrared emissions from the H3+ molecular ion show how the ionosphere responds to those inputs. Between 1995 and 2000 Spectroscopic, J.E.P Connerney & T. Satoh carried out observations with the NSFCAM imaging instrument at the NASA Infrared Telescope Facility. Results from this data set have been published, although the entire data set has not been examined and there has been only limited comparison with the UV. We reanalyze this data set in order to statistically characterize the infrared aurora and compare with the UV. Here we present a detailed study of simultaneous and near-simultaneous observations of the UV (STIS instrument on HST) and infrared northern aurorae made on July 26, 1998 and December 16, 2000. The comparative study addresses the main oval emissions, satellite footprints, and polar aurorae. M. Lystrup is supported by an NSF Astronomy and Astrophysics Postdoctoral Fellowship under award AST-0802021. [less ▲]

Despite their extreme adaptation to life in open sea, ichthyosaurs were one of the first major groups of post-Triassic marine reptiles to disappear, at the end of Cenomanian, whereas plesiosaurs, mosasaurs and numerous families of marine crocodiles and sea turtles disappeared during the Cretaceous/Paleocene Extinction Event. It has been proposed that unique biological factors drove ichthyosaurs to extinction, namely a break in the food chain at the level of belemnites or a progressive ecological replacement by teleost fishes since the Middle Jurassic. However, new discoveries in France and Russia turn both these hypotheses unsatisfactory because ichthyosaur diversity remained high during the Early Cretaceous both from taxonomic and ecological points of view, with the persistence of several Late Jurassic genera into the Early Cretaceous and the colonization of various feeding guilds. The extinction of ichthyosaurs during the Cenomanian was therefore more sudden than previously described. The present study aims at replacing the extinction of ichthyosaurs within the global context of changes in marine ecosystems during the ‘middle’ Cretaceous. The ‘middle’ Cretaceous (Aptian-Turonian) is indeed punctuated by numerous and profound global climatic and oceanic changes, as well as intense underwater volcanism. These factors led to recurrent anoxic events, sometimes of worldwide extension. Interestingly, the peak of changes in the geosphere, taking place during the Cenomanian, coincides with major biological changes within the marine realm: the rise of polycotylid plesiosaurs, marine squamates, teleost fishes and chondrichtyans, the onset of the “Chalk sea”, and an extinction within marine invertebrates communities. Ichthyosaurs disappeared during this profound reorganization of the marine ecosystems. However, the precise mechanisms that lead to the sudden extinction of these successful marine reptiles cannot be understood in the current state of our knowledge given the multitude of possible causes occurring at the same time.

Significant climatic changes are currently observed and, according to projections, will be strengthened over the 21st century throughout the world with the enhanced greenhouse effect. Climate will be generally warmer with notably changes in the seasonality and in the precipitation regime. The CARAIB dynamic vegetation model is used to evaluate and analyse the potential impacts of climate change on forests ecosystems in Europe. Changes in the hydrological budget as well as in the intensity and the frequency of wildfires and their effects on forest productivity and distribution are especially assessed. CARAIB is driven by the ARPEGE-Climat model and some other regional climate models from the European Union (EU) project ENSEMBLES forced with IPCC A1B emission scenario. Climate projections indicate changes in variability and frequency of extreme events. Since climate variability governs the response of plant species (e.g. net primary productivity, NPP) to climate change, we analyse the climate variability (seasonal and interannual) given by climate models comparing it with the observed climate variability (CRU TS 3.0 historical climate dataset) over the period 1961-1990. The variability modelled by the ARPEGE-Climat model is notably slightly more pronounced than the observed one, at least for some areas. Since discrepancies between modelled and observed current climate variability may affect NPP variability calculated for the future as well as the intensity and the frequency of severe drought period and wildfires, comparing the forest ecosystem evolutions obtained with a range of climate models allows improving the assessment of climate change impacts on forest in the future.

For ligan-binding assay, different parameters are controlled in routine. In a development phase, we will show how design of experiment can be used to select these parameters to obtain reliable results in the future use of the ELISA test. Uncertainties of measurements and models should be taken into account in a predictive manner. Bayesian modelling and MCMC simulations are well suited for this purpose and are flexible enough to include random effects on the parameters on non-linear model. We will focus on 4PL regression as it is encountered in most applications. We will also show that deriving a quality response such as a precision profile is clear and direct in the Bayesian setting. The approach is fully compliant with QbD guidelines and Design Space definition. [less ▲]

We study the phylogeography of Leopoldamys neilli, a threatened murine rodent species endemic to limestone karsts of Thailand, in order to assess the influence of its endemicity to karstic habitat on its intraspecific biodiversity and phylogeographic pattern. Samples of L. neilli were collected in limestone karsts from 20 localities in seven provinces of Thailand. Two mitochondrial markers, the cytochrome b gene (cytb) and the cytochrome c oxydase subunit I gene (COI), were sequenced for 115 L. neilli individuals. A nuclear fragment, the β-fibrinogen intron 7 (bfibr), was amplified in a subset of 65 samples. Phylogenetic reconstructions and median joining networks were used to explore relationships between haplotypes of the studied populations. Haplotype and nucleotide diversities of the main lineages were estimated for each locus. Divergence times of the main lineages of L. neilli were estimated using Bayesian inference. The demographic histories of the main lineages of L.neilli were also examined. Our study gave evidence of a strong geographic structure of the genetic diversity for L. neilli. Six highly differentiated genetic lineages were observed in the phylogenetic and phylogeographic analyses. These lineages are allopatric and correspond to particular regions of Thailand. They exhibit very high degree of genetic divergence and gene flows between them are extremely low. Within each lineage, the levels of haplotype and nucleotide diversities are very low for each gene. These results suggest a severe fragmentation of L. neilli’s populations, correlated to the fragmented distribution of its habitat and highlight its high endemicity to limestone karsts. The strong phylogeographic pattern of L. neilli and the very ancient separation of some lineages could be explained by the geological history of Thailand during Tertiary and Quaternary era. In conclusion, this study revealed an unexpectedly high level of intraspecific biodiversity within the species L. neilli. These results consolidate the importance to strengthen the protection of limestone habitats and to preserve not only their huge interspecific but also intraspecific biodiversity. [less ▲]

The question of lowering the voting age to 16 has long been debated in university circles. In the last Austrian elections, young people aged 16 and older were invited to vote, even if young people themselves are divided over this issue, even hostile to the idea. Nevertheless, isn’t such a question, which is rarely discussed by the larger public and touches on several dimensions of a person’s life, an ideal topic for a debate, where the confrontation of ideas may change opinions and reveal – or even modify – young people’s global attitudes towards political interest and participation? A non-random sample of nearly two hundred 16- to 22-year-old youth in French-speaking Belgium was selected to discuss the possibility of lowering the voting age to 16, as well as political interest and political participation, during one day with four experts. The same questionnaire was filled in in the beginning and at the end of the day to measure the changes in opinion. But those changes are not the most interesting ones in this research. When we analysed the discussions of the young people during the focus groups, it was possible to bring out real patterns of political reasoning in the discourses. The first results presented here open interesting research paths, particularly for the study of political socialization. [less ▲]

Par l’analyse d’un ensemble de textes rédigés aussi bien par des anglophones que des francophones d’Amérique du Nord dans la seconde moitié du 20e siècle, nous nous proposons d’envisager les conceptions présidant à la rédaction de l’histoire de la langue. Par le biais de l’étude de la dénomination des variétés de langue (qu’il s’agisse des variétés vernaculaires ou de la variété prise comme étalon de référence), nous mettons au jour les idéologies et représentations linguistiques bien vivantes qui transparaissent derrières des catégorisations souvent considérées comme consensuelles. La mise en rapport des choix terminologiques et des hypothèses historiographiques défendues (encore très diversifiées) semble montrer comment les idéologies orientent la description historique. Ce n’est pas seulement dans les thèmes développés qu’elles se reflètent, mais aussi dans les événements ou polémiques passés sous silence. Dans des contextes comme l’Acadie et la Louisiane, où le français est minoritaire, la place de la langue dans l’affirmation identitaire est prépondérante. Au même titre que l’histoire, la religion et la culture, elle fait l’objet de représentations qui ont pu se marquer dans tous les types de discours. Cependant, il peut paraître paradoxal, dans ces deux ensembles francophones hétérogènes, que l’histoire de la langue soit aussi parcellaire et toujours subordonnée à d’autres problématiques et préoccupations. Il s’agira, lors de cette présentation, d’esquisser des réflexions sur les conséquences de ce traitement historiographique conditionné de la langue ainsi que sur les conditions sociohistoriques et sociolinguistiques qui peuvent expliquer une telle situation.

Physical particle packing is becoming a hot topic in concrete technology as more and more types of granular materials are used in concrete either for ecological or for engineering purposes. Aggregate is used as concrete’s skeleton, whereby the particles are stabilized by the cementitious matrix. Packing efficiency governs the spatial characteristics of this structure and thereby influences concrete’s properties. Fine-grained sand can be used to further improve density of the aggregate structure. The particulate cement is also frequently blended by fine mineral admixtures to influence performance of the paste and the properties of the matured concrete. The so-called filler effects increase packing density of the blended cement and possibly reduce water demand. High performance characteristics require suitable blending materials of proper properties (fineness, shape, chemical components, etc.). A number of theoretical packing models have been proposed for prediction of packing characteristics and the resulting concrete properties. A minimum voids ratio has been mathematically derived for certain particle size distributions. This allowed establishment of some optimum graded mixtures for concrete production. On the other hand, the computer simulation approach provides a powerful tool for simulating particle packing. Computational concrete (compucrete) has been developed for a wide range of research purposes. Application of computer simulation to particle packing offers a promising perspective in concrete technology; it provides a proper representation of the heterogeneous concrete material, and renders the possibility of studying the effects of a wide range of technological parameters. In this study, an advanced DEM will be utilized for investigate the packing properties of admixtures blended cement. This new-developed system is capable of packing simulations of arbitrary-shaped particles. Experimental shape analysis of each identical group of particles provides fundamental references of shape simulation strategy. Finally, computer simulation structures of blended cement paste both in fresh and hardened states will be compared with the experimental approach. Correlation of particle packing characteristics and properties of blended cement paste will be analyzed and discussed. Optimization of blending efficiency and improvement of concrete properties are pursued using packing modeling. [less ▲]

1) Introduction La préparation de semainiers pour les patients des maisons de repos et de soins (MRS) par le pharmacien d’officine permet de diminuer les erreurs liées à l’administration des médicaments. Outre ce bénéfice, l’accès pour le pharmacien à l’ensemble du traitement devrait faciliter la validation pharmaceutique des prescriptions et le développement de soins pharmaceutiques de qualité pour les patients résidant en communauté. 2) Contexte de l’étude La MRS étudiée est une institution publique de la Communauté Germanophone où résident 143 patients répartis dans 6 services différents. Le système de gestion des médicaments est en phase de transition. Pour 3 salles, la préparation et la distribution des médicaments sont assurées par les infirmières de salle (=groupe contrôle). Pour les 3 autres salles, le pharmacien d’officine prépare des semainiers pour les formes orales solides, la préparation des autres formes pharmaceutiques et la distribution des médicaments étant assurées par les infirmières (=groupe intervention). 3) Objectifs Le but de l’étude est de comparer ces deux modes de préparation des médicaments en termes quantitatifs (nombre de médicaments et nombre de prises) et qualitatifs (médicaments inappropriés et interactions). 4) Méthode En octobre 2009, les traitements de tous les patients de l’institution ont été enregistrés sur base des plans d’administration de la MRS. Les médicaments inappropriés ont été évalués sur base d’une adaptation française de la liste de Beers. Les interactions médicamenteuses a été analysées à l’aide du logiciel Micromedex® sur un échantillon de 20 patients par groupe, stratifié selon le nombre de médicaments. 5) Résultats 143 patients ont été enrôlés dans l’étude (67 pour le groupe contrôle et 76 pour le groupe intervention). L’âge moyen (82,4±8,3) est semblable entre les groupes, contrairement à la répartition homme/femme, la durée de séjour et le score de Katz. Le nombre de médicaments/patient (7,9±4,4 vs 8,7±3,7 ; p=0,23), le nombre de prises/patient (10,8±6,9 vs 11,8±5,5 ; p=0,36) et le nombre de médicaments inappropriés/patient (1,0±0,9 vs 1,0±0,9 ; p=0,73) ne sont pas différents entre les deux groupes, même après ajustement pour le sexe, la durée de séjour et le score de Katz. Le nombre d’interactions majeures/patient (0,8±1,3 vs 0,9±1,5 ; p=0,73) est similaire dans les deux groupes. 6) Conclusion En résumé, la préparation de semainiers par le pharmacien d’officine n’entraine pas de différence statistiquement significative du point de vue quantitatif et qualitatif sur la pharmacothérapie des patients en MRS.

It is now established that several species of amphipods associated to Mediterranean Posidonia oceanica meadows consume the epiphytes present on the leaves of the seagrass. However, little or no work has been undertaken to quantify this interaction. Here, we present the results of an in vitro experiment that used seagrass mimics to estimate the impact of grazing by the amphipods Apherusa chiereghinii, Dexamine spiniventris and Gammarus spp on the dynamics of the epiphytic cover. All species reduced epiphyte biomass in a significant way, and grazers preferentially fed on erected algae. Assimilation of epiphyte-derived carbon and nitrogen was monitored using stable isotopes (13C and 15N) labelling, and was obvious in the three taxa. Moreover, grazing activity of amphipods seemed to influence epiphyte physiology, notably by increasing nitrogen uptake by the erected algae. These results shed light on trophic interactions between the amphipods from Posidonia oceanica meadows and the seagrass epiphytic cover, and thus enhance our understanding of the role of these grazers in the functioning of the meadow as an ecosystem.

Since the early 1990s in Wallonia, coagulase negative staphylococci (CNS) have been identified as mastitis agent, both clinical and subclinical. As there epidemiological cluster has not yet been clearly classified between environmental and contagious pathogen, several questions subsists toward this class of mastitis etiological agents. From the late 1990s were the CNS represented 12% of infected quarters to 23% of all positive identifications in 2008, the CNS have taken a large part of the clinical cases of mastitis. Comparatively, CNS in Flanders represents only 7% of clinical cases identifications and 24% of subclinical cases. They still represent low inflammation pathogens, as for the average somatic cell count (SCC) of a CNS infection is 450.000 cells/ml (DETILLEUX, J. 1999. Preventive Veterinary Medicine, 41, 75-88.) but they represent for sure a source of treatment events in farm as for they provoke clinical mastitis. So, however they are seen as minor pathogens of a lesser matter regarding milk production drop, they still can imply a treatment a loss of discarded milk. Whether or not they should be treated could be approached through the Mammipack® project results. 124 common clinical mastitis events where sampled for bacteriology at day 0 and day 21 (Fig. 1). Farmer were asked to qualify the severity of the mastitis whether it had abnormal milk (score 1); abnormal quarter (score 2) or hyperthermia/anorexia (score 3). Also, they recorded the treatment used and we collected the SCC of each cow recorded, 2 months before the clinical signs until 3 months after. We decided to define as “chronic cases” cows showing SCC > 250.000 cells/ml the month before the clinical event and as “cured” cows showing SCC < 250.000 cells/ml the month after the event or the next one if the mastitis took place less than 15 days before test day. We could show that CNS infections still account for the least severe cases (Fig. 2), except for S. simulans, S. saprophyticus and S. hominis that shown some quarter indurations. While only 10% of clinical infection does remain clinically uncured to the farmer, figure 3 explains how 50% of CNS infections in our essay remained globally cured (Bacteriological and tissular), even if 40% of their treatments shown to be inadequate. Also, only one infection could be referred as a chronic case, all the others were acute cases. Though this study recorded a small amount of cases, yet we did not find any results differing from known characteristics of CNS infections. One interesting facts is the quite easy cure of the infected quarters given the poor quality of treatment. [less ▲]

Endotoxemia is the first mortality cause in intensive care horses. In human, hemodynamic disturbances have been showed to be associated with septic shock whereas in horses, this facet of endotoxemia has not yet been studied. The aim of the study was to assess the impact of endotoxin shock on equine cardiac function. Fifty horses admitted in clinic with signs of endotoxic shock and 17 healthy control horses were submitted to a doppler echocardiographic exam. The endotoxemic horses were classified in 4 groups according to their shock score based on clinical evaluation (heart rate (HR) and respiratory rate), non invasive systolic blood pressure, and blood tests (Packed cell volume and lactates). Score 1, 2, 3 and 4 groups included 11, 17, 12 and 10 horses, respectively. Left ventricular (LV) echocardiographic and Doppler parameters were compared between the 5 groups using a multivariable ANOVA analysis. The LV internal diameter, ejection time, ejection time corrected for HR and mean velocity of circumferential fiber shortening corrected for HR, the aortic velocity time integral and deceleration time, and the stroke volume were significantly lower, whereas the HR and the peak velocity of the late diastolic filling of the mitral Doppler flow and its velocity time integral were significantly higher in grade 2 to 4 endotoxemic horses than in control horses. Because of the tachycardia compensating the lower stroke volume in endotoxemic horses, the cardiac output was not significantly different between groups. Despite the fact that the increase in HR, the fall in preload and a probable decrease in afterload doubtless played a role in the observed changes, the results of this study suggest an impaired systolic and diastolic LV function in horses with moderate to severe endotoxemia. Doppler echocardiographic monitoring of the cardiovascular function could thus be of interest in equine intensive care. [less ▲]

Geographic profiling is a methodology that uses the location of a series of crimes attributed to the same offender in order to determine the residence of this latter. This recent discipline links the theories of environmental criminology, such as the routine activity theory, with the techniques of spatial analysis offered by the Geographic Information Systems such as centrographic statistics and distance decay functions. The literature differentiates two categories of serial offenders according to their mobility: the marauder committing his crimes in the nearby area of his home and the commuter travelling outside his daily activities area. Until now, geographic profiling methodologies have proven to be effective only for the marauder behaviours. Before applying these spatial techniques, it is therefore essential to know what kind of offenders we are facing. However, few studies have tried to determine how these two behaviours could be identified on the basis of crime scene information and suspect’s characteristics. Moreover, spatiotemporal aspects have very often been underexploited. After an introduction to geographic profiling, we present the existing typologies of offender spatial behaviours, among which the commuter/ marauder dichotomy. We set out the crucial information identified in the literature aiming at their differentiation and their implication on the method used to reduce the search area. We draw a conclusion that some spatial inconsistencies persist, requiring to revisit the typologies according to multiple spatiotemporal patterns. Particularly we demonstrate how these typologies can be enhanced by taking into account the relation between the moment of the crime and the location of the crime site. Finally, we show that these new patterns can improve the analysis of commuters thanks to techniques based on spatiotemporal constraints. [less ▲]

Classical criminology was mostly developed in the field of local penal law. Thus, protective and repressive measures taking part in these judicial systems are often limited to local aims. In this criminology, the State is protective, the care for victims is institutionalized. Moreover, the relation between criminology and penal qualification of the act against the victim as a crime is essential to access the status of victim. This entails an epistemological presupposition in victimology, science considered as a specialized field of criminology. Indeed, this presupposition makes the victim of serious violations of penal Law the prototype of victims of serious offenses. Furthermore, crime is not only a matter of individuals but also of structural possibilities, as is the case in criminal organizations. In the subject matter of organized criminality, the sides taking in concern in classical criminology are mostly related to economical delinquency. State or governmental army criminality is rarely explored by researchers. Previously, these topics seemed to be unreachable, but the nature of the recent armed conflicts, and the present evolution of International penal Law, entailed to the visibility of massive atrocities during wars. Today, criminology must face new fields of involvement, larger than these investigated in classical criminology. Presently, an international criminology is emerging, which is different and liberated from classical criminology. In this international criminology, a special kind of criminality is studied, due to its massiveness, its extent and is systematic nature. In addition, a strong war victimology is emerging as well, victimology tends thus to be an autonomous discipline. The challenge is now to turn crisis criminology and victimology into a strong scientific discipline. [less ▲]

Agencies have historically developed in Belgium, endorsing public activities not only at the federal level, but also at the level of decentralised governments (regions and communities). The current landscape in the Southern part of the county is more and more taking the form of a mosaic with very little efforts in terms of cooperation : this is particularly true when the agencies addressing similar target groups in a given sector are responding to different levels of governments with very little interaction, the coordination being organised by the users' themselves, according to their own strategies. At the same time, some agencies are taking more of a centre stage position : they not only provide services and support to their target group, they also fruitfully contribute to their status and identity building. Using a cultural approach may help study the "art of the state" in its diversity (Hood, 1998). We propose to concentrate the analysis on the emergence of two Agencies whose mission is to support professionals working in the public sector. Based on a recent field work on the transformation of the sector of public research, we will analyse how the FNRS (an agency funding public research) succeeded to survive as an independent agency through since 1928 (Halleux & Xhayet, 2008), adapting to the transforming socio-political context: it emerged as an industry based project and transformed into a "mertonian" institution of knowledge contributing to unify the scientific community at the level of the country, while bypassing the historical divisions of the three worlds of universities in the country (Fallon, 2009). A diachronic analysis helps underline how socially constructed is such an institution, and how the configuration of networks are continuously reshaping themselves to better be embedded in a specific historic society (Laborier, 2003). The FNRS is currently struggling to define new forms of cooperation with the universities (and their researchers) which are themselves embarked in the current stream of transformations introducing techniques derived from New Public Management in research organisations (de Boer, Enders, Schimank, 2007). In quite a different sector, another field work using the same methodological approach analysed the emergence of a very recent agency, EASI-WAL, serving the regional administration in order to encourage administrative simplicity (OCDE, 2003, 2005) and reported the shortcomings of this organisation in organising avenues for professional change with the civil servants (Thoreau, Fallon, Joris,2009). The two field work research were organised as case study analysis, with document analysis, face to face interviews and in situ observation, using research tools derived from the sociology of science (Actor-Network Theory in Callon,1986). The paper will present the outcomes of the analysis of the dynamics of the cooperation between the agency and its target groups (FNRS & researchers; EASI-WAL & civil servants) and their outcomes in terms of innovation and organisational learning. We observe the implementation of two institutions both designed to support the emergence of some common goal within their target collectives (elitist -research; administrative simplicity): they autonomously gave shape to their internal procedures of categorisation and hierarchisation, with identification processes contributing to the definition of institutional boundaries defining a specific field while ensuring its inscription in the network through a specific legitimating strategy (Douglas, 1986). This analysis will unveil some of the mechanisms of cooperation of the different stakeholders supporting the institution, and also the struggle between stakeholders for the definition of settings of participation and administrative and political control.

Background: TADAM, a randomised controlled trial of heroin-assisted treatment, will begin in Liège, Belgium, in 2010. This trial will compare two groups of patients: one in a heroin-assisted treatment and the other in oral methadone treatment. In this new medical treatment, the criminal behaviour of the patients will also be assessed. It is one of the three efficacy criteria. Why? Methodology: We based our presentation on papers published on heroin-assisted treatment concerning changes in criminal behaviour. Results: Heroin-assisted treatment of treatment resistant heroin addicts has been successfully tested in six countries: Switzerland, The Netherlands, Spain, Germany, Canada and United-Kingdom. Each country has also assessed the criminal behaviour before and after the treatment with better results for heroin-assisted treatment than for methadone treatment. Conclusion: HAT seems a good way to treat criminal behaviour of a group: severely heroin addicts who already tried other treatments. [less ▲]
