The inability to vocally match a pitch can be caused by poor pitch perception or by poor vocal-motor control. Although previous studies have tried to examine the relationship between pitch perception and vocal production, they have failed to control for the timbre of the target to be matched. In the present study, we compare pitch matching accuracy with an unfamiliar instrument (the slider) and with the voice, designed such that the slider plays back recordings of the participant’s own voice. We also measured pitch accuracy in singing a familiar melody (“Happy Birthday”) to assess the relationship between single pitch matching tasks and melodic singing. Our results showed that participants (all nonmusicians) were significantly better at matching recordings of their own voices with the slider than with their voice, indicating that vocal-motor control is an important limiting factor on singing ability. We also found significant correlations between the ability to sing a melody in tune and vocal pitch matching, but not instrumental pitch matching. Better melodic singers also tended to have higher quality voices (as measured by acoustic variables). These results provide important evidence about the ultimate causes of poor singing ability, and demonstrate that single pitch matching tasks can be useful in measuring general singing abilities.

La banque de graines du sol des forêts denses humides africaines a été très peu étudiée, alors qu’elle pourrait jouer un rôle déterminant dans les cycles sylvigénétiques naturels. Elle pourrait également être avantageusement utilisée dans les programmes de restauration, à l’instar de ce qui se fait sur d’autres continents. La présente synthèse bibliographique fait le point sur les connaissances actuelles relatives à la banque de graines du sol, en mettant l’accent sur le continent africain. Elle montre qu’une meilleure caractérisation de la banque de graines du sol des différentes communautés végétales constituerait une contribution notable pour la gestion durable des forêts tropicales d’Afrique.

Le photogramme est, au cinéma, la plus petite unité de prise de vue. Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux.

Burkitt lymphoma (BL) is a rare but very aggressive non-Hodgkin’s lymphoma characterized by an isolated translocation t(8;14)(q24;q32). The sporadic form is the subentity most frequently encountered in our country. Diagnosis and initial work-up must be completed rapidly to start treatment as soon as possible. Positron emission tomography (PET) scan is useful for initial staging and to evaluate the chemosensitivity of the tumor during and after treatment. After debulking, it is recommended to add rituximab to chemotherapy. Currently intensive short-cycle chemotherapies (ISCC) and low intensity chemotherapies (LIC) are two valuable options. Radiotherapy is not indicated except in case of central nervous system involvement. Patients achieving complete remission must be followed carefully during the first year to detect recurrence of the disease. More than 80% of patients sustain their remission one year following initial treatment and are considered cured. For patients in partial remission or with chemosensitive relapse, autologous stem cell transplantation is recommended following re-induction with non-cross-resistant polychemotherapy. Monitoring complete blood counts and cognitive functions is important to detect late toxicity of the applied therapies. [less ▲]

In this double blind, unicentre, randomized, placebo controlled study, we evaluated the changes in 25-hydroxyvitamin D (25(OH)D) serum levels in 150 young Belgian adults (18–30 years), monthly supplemented with 50,000 IU of vitamin D (VTD) or placebo for 6 months, from November 2010 to May 2011. At T0, 30% of the population presented 25(OH)D serum levels below 20 ng/mL. In the VTD-treated group, mean serum levels increased from 21.2 ± 8.2 to 30.6 ± 8.8 ng/mL (𝑃 < 0.001) at T3mo and to 36.0 ± 9.2 ng/mL (𝑃 < 0.001) at T6mo. Despite documented VTD intake, no changes in serum levels were, however, observed in 10% of the treated group. In the placebo group, mean 25(OH)D serum levels decreased from22.8 ± 8.5 to 14.0 ± 6.9 ng/mL at T3mo (𝑃 < 0.001) but returned to values not significantly different from those observed at T0 (23.5 ± 8.6 ng/mL) at T6mo. No difference between serum calcium levels was observed between the groups throughout the study. In conclusion, monthly supplementation with50,000UIofVTDinwinter canwarrant serum25(OH)Dlevels above 20ng/mL in96.2%of thosehealthy young adultswithout inducing unacceptably high 25(OH)D concentration. This supplementation is safe andmay be proposed without 25(OH)D testing. [less ▲]

There is a wide recognition of the watershed scale as the right scale for global water management, notably in the context of the WFD. Hence, it often refers to international management and therefore to various pre-existing regional management tools, models or even objectives. In this study we aim at describing the collaborative assessment of climate change’s effect on low flow regime and the consequences on three water related sectors: drinking water production, agriculture and electricity production. The paper highlights the choices that were made during the study that involved scientific teams, managers and stakeholders from the four main countries of the Meuse Basin. It shows that the methodological choices were operational and aimed at preserving existing methods and knowledge within each country. They led to hydrological scenarios comparable to the main available ensemble approaches and to methodologies well accepted within the concerned countries. The results of the project highlight and quantify the water scarcity that the three sectors will have to face by the end of the century mainly regarding the electricity production. They also show that common allocation rules are necessary to manage water demand during future low flow periods. [less ▲]

The aim of this study is to compare the effect of different homogenization treat- 12 ments on the physicochemical properties and the hydrolysis rate of a pure bleached 13 cellulose. Results obtained show that homogenization treatments improve the enzymatic 14 hydrolysis rate of the cellulose fibers by 25 to 100 %, depending of the homogenization 15 treatment applied. Characterization of the samples showed also that homogenization had an 16 impact on some physicochemical properties of the cellulose. For moderate treatment inten- 17 sities (pressure below 500 b and degree of homogenization below 25), an increase of water 18 retention values (WRV) that correlated to the increase of the hydrolysis rate was highlighted. 19 Result also showed that the overall crystallinity of the cellulose properties appeared not to be 20 impacted by the homogenization treatment. For higher treatment intensities, homogenized 21 cellulose samples developed a stable tridimentional network that contributes to decrease 22 cellulase mobility and slowdown the hydrolysis process.

BACKGROUND: We have previously shown that short sessions of whole body vibration (WBV) were not able to significantly improve fall risk among nursing home residents but some trends towards an improvement of motor capacity were observed. OBJECTIVE: The objective of the present study was to evaluate the impact of 6-month training by WBV on functional and motor abilities among nursing home residents observed over a 12-month period. METHODS: Patients were randomized into two groups: the WBV group which received three training sessions every week composed of five series of 15 s of vibration at 30 Hz intensity for a period of 6 months and a control group with normal daily life. The impact of this training on the risk of falls was assessed blindly after 6 and 12 months by the Tinetti Test, the "Timed Up and Go" test and a quantitative evaluation of a 10-s walk performed with a tri-axial accelerometer. The occurrence of falls was also observed. RESULTS: 62 elderly healthy volunteers, (47 women and 15 men, mean age 83.2 +/- 7.9 years) were included in this study. There was no significant difference between the two groups regarding the Tinetti test (p = 0.75), the "Timed Up and Go" test (p = 0.19) and the Locometrix(R) test, except for the step length, measured by dual task (p < 0.01). No significant inter-group difference in the frequency of falls was observed during the 12 months of research. A total of 42 falls were recorded during the first 6 months of experimentation: 24 falls in the treated group and 18 in the control group (p = 0.60). During the next 6 months, 19 falls occurred: 8 falls in the treated group and 11 in the control group (p = 0.52). CONCLUSION: This study failed to establish the effectiveness of low doses of WBV, under the conditions used in our study, on functional and motor abilities of institutionalized elderly patients. However, given the positive results of other studies, further investigations, with modified therapeutic protocols, seem necessary to clarify the effects of WBV in the elderly. [less ▲]

This case study analyses how far donors implement aid effectiveness principles at health district level in Mali, and why. It shows that not all aid effectiveness principles are implemented at a similar degree. Most projects have limited impact on health services, but many programmes supported by donors offer positive opportunities for health system strengthening. The representations of different categories of stakeholders diverge – notably, regarding the role of different actors in service provision. A number of consistent strategic logics influence actors’ behaviour. We show that while many donors have committed at global level to respect aid effectiveness principles, implementation lags behind.

Jatropha curcas, ou Pourghère, est un arbuste de la famille des Euphorbiacées, largement répandu dans les pays tropicaux. Ses graines sont riches d'une huile pouvant servir de biocarburant dans les moteurs diesels modifiés. La plante est attaquée par divers insectes ravageurs appartenant principalement aux ordres des Hétéroptères, Coléoptères et Orthoptères. Ils provoquent des dégâts sur les fruits, les inflorescences et les feuilles. Les ravageurs les plus fréquemment observés sur J. curcas sont des punaises du genre Pachycoris (Hétéroptère : Scutelleridae), qui sont largement répandues au Mexique, en Australie, aux États-Unis, au Brésil et au Nicaragua. Ces punaises causent des dégâts importants sur les fruits et provoquent la malformation des graines, et avec elle une réduction de la teneur en huile. Même si les arbustes de Jatropha sont victime d'infestations d'insectes, plusieurs études démontrent l'effet insecticide de son huile contre des ravageurs importants tels que Busseola fusca (Fuller) (Lépidoptère : Noctuidae), Sesamia calamistis Hampson (Lépidoptère : Noctuidae), Aphis gossypii Glover (Homoptère: Aphididae) et Callosobruchus chinensis L.

Freeplay in aircraft control surface actuators is a common source of nonlinearity that can cause undesirable aeroelastic phenomena and, as a consequence, certification authorities place strict limits on the size of the deadband gaps of actuators. In recent years many authors have worked on determining the effects of freeplay on the dynamic behavior of aeroelastic systems; these efforts have yielded significant improvements in the understanding of the phenomena, but have concentrated on simple models. Investigations of industry-relevant aeroelastic models of complete aircraft with freeplay in the actuators have been much rarer, the main difficulty being the selection of an appropriate modal basis that can represent the full range of possible dynamic phenomena. This work presents a novel implementation of the residual vectors approach to create consistent and numerically stable reduced order models suitable for industrial-standard aeroelastic models of aircraft. The methodology relies on the piecewise linear nature of freeplay to create a single reduction basis that represents the dynamics of the system both inside and outside the freeplay deadband gap. The method is demonstrated on an Embraer generic test bench aircraft, showing that the resulting reduced order model is efficient and effective. Nonlinear analysis is carried out using equivalent linearization as well as time integrations of the full nonlinear system. It is shown that, while equivalent linearization is an indispensable tool for a preliminary mapping of the main aeroelastic instabilities, the time integration-based nonlinear analysis is an essential complementary tool to confirm the characteristics of the system behavior.

This paper aims at studying the effect of corporate disclosures on information asymmetry and stock-market liquidity in France. Specifically, the purpose of this paper is to highlight the importance of information included in the annual reports on investor’s behavior. This is proxied by the information asymmetry component of the bid-ask spread and stock market liquidity. Our sample includes 196 French listed firms over a period ranging from 2004 to 2007. We opt for an explanatory study using OLS regressions to examine the nature of the relationship between information disclosed in annual reports and bid-ask spreads a proxy for information asymmetry and stock market liquidity. The results show that the extent of corporate disclosures in annual reports positively influences the liquidity of the French market and negatively affects the adverse selection component of the bid-ask spread. This effect is further confirmed by the commitment to IFRS by French-listed firms from 2005. The decomposition of the total score in the sub-indices shows that non-financial and financial information are important in trading decisions while strategic information may be attractive only for long-term positions [less ▲]

Objectives: Patients with locked-in syndrome often self-report a higher quality of life than generally expected. This study reports third-person attitudes towards several salient issues on locked-in syndrome. Methods: Close-ended survey among conference attendees from 33 European countries. Analysis included chi-square tests and logistic regressions. Results: From the 3332 respondents (33% physicians, 18% other clinicians, 49% other professions; 47% religious), 90% agreed that patients with locked-in syndrome can feel pain. The majority (75%) disagreed with treatment withdrawal, but 56% did not wish to be kept alive if they imagined themselves in this condition (p50.001). Religious and southern Europeans opposed to treatment withdrawal more often than non-religious (p50.001) and participants from the North (p¼0.001). When the locked-in syndrome was compared to disorders of consciousness, more respondents endorsed that being in a chronic locked-in syndrome was worse than being in a vegetative state or minimally conscious state for patients (59%) than they thought for families (40%, p50.001). Conclusions: Personal characteristics mediate opinions about locked-in syndrome. The dissociation between personal preferences and general opinions underlie the difference in perspective in disability. Ethical responses to dilemmas involving patients with locked-in syndrome should consider the diverging ethical attitudes of stakeholders. [less ▲]

BACKGROUND: Single cell biology has attracted a lot of attention these past few years and has led to numerous fundamental results pointing out the heterogeneity of clonal cell populations. In this context, microbial phenotypic heterogeneity under bioprocessing conditions needs to be further investigated. In this study, yeast based processes have been investigated by using on-line flow cytometry in combination with a fluorescent transcriptional reporter (GFP) and viability fluorescence tags (propidium iodide, PI). Methods aiming at expressing the dispersion of these fluorescence tags among the yeast populations have been investigated for different bioreactor operating conditions. RESULTS: Yeast viability was determined on the basis of PI uptake. Segregation between PI negative and positive subpopulations could be efficiently quantified on the basis of the mean-to-median ratio or the amplitude of the interquartile range. On the other hand, the same quantification could not be made for the segregation occurring at the level of GFP synthesis. Indeed, when cells were exposed to sub-lethal or mild stresses (such as in scale-down reactors) two GFP subpopulations could be visualized by real-time FC, but quantification by one of the above-mentioned methods was not possible. CONCLUSIONS: Yeast population heterogeneity was observed in representative bioreactor operating conditions. Difficulties for the determination of segregation at the level of GFP synthesis point out the fact that one needs to understand the segregation mechanisms for the applied fluorescent reporters, to judge whether simple mathematical tools may be applied or if more sophisticated computational tools are needed for the quantification of the microbial population segregation.

Perception results from a combination of actual data and interpretative schemata based on pre-existing knowledge. Thus, ensuing subjective experience depends on the dynamic interplay between data-driven and conceptually-driven processing. A chronic imbalance between these two sources of stimulus encoding is likely to be maladaptive and could underlie cognitive and behavioral disturbances similar to that observed in schizotypy, especially if the balance is tipped too far towards conceptually-driven processing (i.e., Internal encoding style). This study aimed to examine the relationships between encoding style and various dimensions of schizotypy, by using a questionnaire that evaluates the extent to which pre-existing schemata (versus cues from the outside world) affect encoding processes. Consistent with previous findings, our results revealed that both Cognitive-Perceptual and Disorganization dimensions were related to an internal mode of encoding, suggesting that individuals with these features may be characterized by a disposition to biases at early stages of encoding.

Valorization strategies of wastes from agri-food processes are intertwined with clean technological approaches and eco-industrial management. By-products from Mediterranean agri-food processes such as olive oil, wine and fruit create a considerable disposal problem for the agro-industry. Their characteristics in combination with Mediterranean climate enhance microbial development and can be source of health and safety concerns. After pre-treatment and recovery of valuable precursor materials (lignin, pulp), pyrolysis can be used for fuels, chemicals and carbon bio-based materials production. Since thermal degradation kinetic studies are a key step for the efficient design of thermo-chemical processes, in this study pyrolysis experiments were performed, using TGA for the estimation of the process kinetic parameters.

Urban sprawl is transforming our landscapes and rural areas at a spectacular pace. Measuring the strength of the phenomenon and proposing dynamic ways to delineate suburban areas have been the object of much debate amongst scientists. The present article takes the view that, beyond measuring and delineating suburban areas, more efforts should be directed to qualifying the morphology of built settlements within these areas. Therefore it proposes a method based on a semi-automatic classification system of building clusters, designed to describe and interpret the phenomenon from a morphological perspective. This method is based on a combination of field surveys with numerical analyses of digital land cadastre maps. The application of this classification system to the suburban area around Liege reveals that, far from developing in a complete indifference of local conditions, contemporary suburban settlements are influenced by landscape structures inherited from the past.

Siting controversies are commonplace, as well against the construction of roads, railways, nuclear waste disposals, as against windfarms. Local citizens resist against siting decisions taken by the authorities, following a dynamics often quoted as ‘Not In My Back Yard’. Yet contested for its lack of analytical value, NIMBY is still used strategically by actors to qualify citizens as irrational and egoistic. Beyond this labelling, many factors are investigated to understand the dynamics behind siting controversies. In this paper, we focus on the impact of the legal procedure structuring the implantation of windfarms in the Walloon Region (Belgium), and its translations within different decision making processes in specific case studies. To that regard, we consider the legal procedure as a ‘public policy instrument’. It is neither neutral nor natural, and carry values and interests. It organizes inter-personal relations between actors, and is potentially catalyzer of frustrations. In addition, this legal procedure is the object of translations within different contexts, including different actors participating to specific decision making processes. The empirical approach of this paper is based on case studies data and on the use of an innovative methodology called ‘Open Process Workshop’. This methodology consists in a structured workshop with key stakeholders, during which the legal procedure is questioned. Overall, we demonstrate that the focus on the legal procedure - and its translations within different decision making processes - allows systemic analysis providing deep understandings of controversies and reaffirming the interlinks between ‘the social’ and ‘the technical’ in such controversies. In addition, we argue that the methodology used fosters the production of innovative knowledge, mutual understanding and collective learning between the participants. [less ▲]

Background and aims – Prior to European colonisation of Central Africa, human populations were dispersed through the forests, where they practiced slash-and-burn cultivation. From the 19th century they were progressively concentrated in villages along roads, leaving large areas of forest derelict. In south-western Cameroon, and elsewhere in Central Africa, forest canopy is dominated by long-lived lightdemanding tree species, suggesting a possible role of human disturbance. The aim of this study was to bring new insights into the possible effect of historical human disturbances in terms of timing and spatial extent on the current forest composition. Location – Wet evergreen littoral forest in south-western Cameroon. Methods and key results – A combined vegetation sampling and archaeobotanical survey were conducted. Potsherds, oil-palm endocarps, and charcoal were found throughout the study area, suggesting generalised human occupation and anthropogenic fire. Human occupancy occurred in two periods: between 2200 and 1500 BP, and, more recently, beginning three centuries ago. High frequency of fire and the presence of Elaeis guineensis both dated recently (between 260 and 145 BP) suggest slash-and-burn shifting cultivation practices. These human-induced disturbances may coincide with the age of the current emergent lightdemanding species, the age of which can be estimated around 200 years, or with the phases of drying climate recorded in the Central African forest in the early 18th century. Conclusions – These results support the idea that historical human disturbances are one of the major factors that shaped the current forest composition in Central Africa. [less ▲]

This article proposes to apply Steen’s (2008) 3D model of metaphor analysis in communication to a corpus of political discourse, in this case citizen discourse. Our corpus has accordingly been analysed by making a distinction between three layers of metaphor, respectively at the linguistic (direct vs. indirect metaphors), conceptual (novel vs. conventional metaphors) and communicative levels (deliberate vs. non-deliberate metaphors). Our results suggest that making the distinction between deliberate and non-deliberate metaphors lead to meaningful political insights, notably pointing to differences in saliency of the source domains in terms of which citizens make sense of Belgian federalism. In this regard, the family domain, and more especially the metaphor BELGIAN FEDERALISM IS A LOVE RELATIONSHIP appears to function as an important conceptual reference point for the citizens’ understanding of the political relations in the Belgian context.

La période fin de siècle s’accompagne, dans le champ littéraire français, du développement d’une série de groupuscules plus ou moins organisés et volontiers potaches. Au cœur de ces associations liées de près ou de loin à ce qu’Ernest Raynaud qualifiera de « mêlée symboliste » (1920-1922), le rire fonctionne comme un véritable ciment social, renforçant les liens des membres de la collectivité et redoublant l’exclusion de ceux qui n’en sont pas. Héritiers d’entreprises collectives comme Le Parnassiculet contemporain (1866) et l’Album zutique (composé en 1871 et tenu délibérément à l’écart des circuits de diffusion du livre), les agents engageant les projets des Hydropathes, des Hirsutes, des Jemenfoutistes ou de l’incontournable cabaret du Chat Noir se rassemblent non seulement dans une perspective dérisoire, mais encore se dotent-ils d’un discours qui, plus qu’un simple divertissement, présente cette dérision comme principe régulant l’activité collective. Ce sont, à l’aune des cas susmentionnés, quelques-uns de ces discours du rire collectif fin de siècle que nous explorons ici, en nous penchant sur les mécanismes rhétoriques qui les fondent et sur les grandes logiques (d’opposition à des figures spécifiques ou à des institutions) qui les motivent, en cherchant à mettre en lumière la façon dont cette omniprésence de la dérision est directement provoquée par l’état du champ littéraire de l’époque.

Virus-like particles (VLPs) of human papillomavirus (HPV) are used as a vaccine against HPV-induced cancer, and recently we have shown that these VLPs are able to activate natural killer (NK) cells. Since NK cells collaborate with dendritic cells (DCs) to induce an immune response against viral infections and tumors, we studied the impact of this crosstalk in the context of HPV vaccination. NK cells in the presence of HPV-VLPs enhanced DC maturation as shown by an upregulation of CD86 and HLA-DR and an increased production of IL-12p70, but not of the immunosuppressive cytokine IL-10. This activation was bi-directional. Indeed, in the presence of HPV-VLPs, DCs further activated NK cells by inducing the upregulation of cell surface activation markers (CD69 and HLA-DR). The function of NK cells was also improved as shown by an increase in IFN-gamma secretion and cytotoxic activity against an HPV+ cell line. This crosstalk between NK cells and DCs needed CD40 interaction and IL-12p70 secretion, whereas NKG2D was not implicated. Our results provide insight into how VLPs interact with innate immune cells and how NK cells and DCs play a role in the immune response induced by this vaccine agent.

Populations considered for shoulder analysis are often composed of various ratios of men and women. It is consequently hypothesized that gender has no significant effect on the joint kinematic. However the literature reports, for the shoulder, differences in the range of motion between genders. The specific influence of gender on the scapula-thoracic kinematics has not been studied yet. The dominant shoulder of two populations of men and women composed of 11 subjects each were evaluated in three dimensions for three distinct motions: flexion in the sagittal plane, abduction in the frontal plane and gleno-humeral internal/external rotation with the arm abducted at 90°. Posture, kinematics and range of motion were studied separately. For flexion and abduction and with regard to the scapular kinematic, external rotation were significantly larger for women than men. The differences were of at least 5° at 120° of humeral elevation. Upward rotations were identical. Women also showed larger average active humero-thoracic range of motion. The mean differences were of 13°, 7°, 12° and 5° for abduction, flexion, internal rotation and external rotation, respectively. No difference was observed between the scapular resting positions of both populations. The observed differences concerning both the scapular and humeral patterns would indicate that the shoulder behavior of men and women should not be expected to be similar. [less ▲]

This paper aims at presenting a general versatile time integration scheme applicable to anisotropic damage coupled to elastoplasticity, considering any damage rate and isotropic hardening formulations. For this purpose a staggered time integration scheme in a finite strain framework is presented, together with an analytical consistent tangent operator. The only restrictive hypothesis is to work with an undamaged isotropic material, assumed here to follow a J2 plasticity model. The only anisotropy considered is thus a damage-induced anisotropy. The possibility to couple any damage rate law with the present algorithm is illustrated with a classical ductile damage model for aluminium, and a biological damage-like application. The later proposes an original bone remodelling law coupled to trabecular bone plasticity for the simulation of orthodontic tooth movements. All the developments have been considered in the framework of the implicit non-linear finite element code Metafor (developed at the LTAS/MN2L, University of Liège, Belgium - www.metafor.ltas.ulg.ac.be).

The stay cables on cable-stayed bridges have been the subject of considerable research in order to understand the origins of the dry galloping phenomenon. Surface irregularity is one of the last parameters that have not been thoroughly examined. This paper focuses on static wind tunnel tests on original High Density Polyethylene cable covers in a range of Reynolds numbers from the sub-critical regime to the critical, corresponding to values ranging from Re = 9.6x104 to Re = 3.3x105. The experiment consists in testing cable covers of various diameters in order to investigate the effect of surface irregularity (roughness and circularity defect) on the mechanism of dry galloping excitation. Previous studies reported that dry galloping is caused by the appearance of a negative pressure bubble on one side of the circular cylinder at the critical Reynolds number range, leading to a rapid drop in the drag coefficient and the appearance of a non-negligible lift force. The results of the present investigation demonstrate that there is a clear correlation between the single bubble pressure pattern and the circularity defect along the tube. They further show that surface roughness has little effect on the location of the bubble. The paper also treats the spatial and temporal correlation of the instantaneous pressure pattern along the tube with respect to the circularity defect. [less ▲]

Body weight (BW) of dairy cows can be estimated using linear conformation traits (calculated BW; CBW), which are generally recorded only once during a lactation. However, predicted BW (PBW) throughout the lactation would be useful, e.g., at milk-recording dates allowing feed-intake prediction for advisory purposes. Therefore, a 2-step approach was developed to obtain PBW for each milk-recording date. In the first step, a random-regression test-day model was used with CBW as observations to predict PBW. The second step consisted in changing means and (co)variances of prior distributions for the additive genetic random effects of the test-day model by using priors derived from results of the first step to predict again PBW. A total of 25,061 CBW from 24,919 primiparous Holstein cows were computed using equations from literature. Using CBW as observations, PBW was then predicted over the whole lactation for 232,436 dates corresponding to 207,375 milk-recording dates and 25,061 classification dates. Results showed that using both steps (the 2-step approach) provided more accurate predictions than using only the first step (the one-step approach). Based on the results of this preliminary study, BW of dairy cows could be predicted throughout the lactation using this procedure. These predictions could be useful in milk-recording systems to compute traits of interest (e.g., feed-intake prediction). The developed novel method is also flexible because actual direct measurements of BW can also be used together with CBW, the prediction model being able to accommodate different levels of accuracies of used BW phenotypes.

The flight of barnacle geese at airspeeds representing high-speed migrating flight is investigated using experiments and simulations. The experimental part of the work involved the filming of three barnacle geese (Branta Leucopsis) flying at different airspeeds in a wind tunnel. The video footage was analysed in order to extract the wing kinematics. Additional information, such as wing geometry and camber was obtained from a 3D scan of a dried wing. An unsteady vortex lattice method was used to simulate the aerodynamics of the measured flapping motion. The simulations were used in order to successfully reproduce the measured body motion and thus obtain estimates of the aerodynamic forces acting on the wings. It was found that the mean of the wing pitch angle variation with time has the most significant effect on lift while the difference in the durations of the upstroke and downstroke has the major effect on thrust. The power consumed by the aerodynamic forces was also estimated; it was found that increases in aerodynamic power correspond very closely to climbing motion and vice versa. Root-mean-square values of the power range from 100 W to 240 W. Finally, it was observed that tandem flying can be very expensive for the trailing bird. [less ▲]

Objective: The objective of this paper is to propose, starting from the description of a clinical emblematic case, a theoretical synthesis of the work of phenomenological psychopathology dedicated to melancholia and typus melancholicus (TM), a clinical concept that describes the premorbid personality vulnerable to major depression (“melancholia” for the psychopathological tradition). Method: This is phenomenological analysis of a case study of melancolia, of its premorbid personality and pathogenic triggering situation. We adopt two main phenomenological keys to understanding the develpment of melancholia : role-identity theory and desynchronization theory. The former understands melancholia as a disorder of identity triggered by the loss of the social role with which one has previously over-identifed. The latter sees melancholia as the effect of the desynchronisation from the social environment that further develops into an inhibition of the conative–affective dynamics of life. We present the case of Jonas (64 years old), whose mother (94 years old) recently died. Before his mother’s death, Jonas’ life was entirely orchestrated by the caring for his mother and synchronized in time with this (e.g., he used to go to her house every 4 hours, took all his meals with her, etc.). Jonas, in addition to being hyper-synchronized and hyper-syntonic, fulfills all diagnostic criteria for TM, including “orderliness”, “conscientiousness”, “hyper/heteronomia” and “intolerance of ambiguity”. TM’s attach a disproportioned importance to their social roles (or external representations of identity) at the expense of their own ego-identity. Results: The passage from pre-morbid personality to melancholia is triggered by the death of Jonas’ mother that entails a profound depersonalization. Desynchronization and role loss cause Jonas fall into this severe depersonalization, whose core feature is the feeling of the loss of feeling. Conclusions: This original contribution demonstrates a clinical case can contribute to the construction and refinement of theoretical and conceptual frameworks (like princeps Tellenbach's studies). Over-synchronized tempo and over-identification with social role are emblematically in this case the two sides of the same coin. A parallelism can be established between synchronization (with the mother) and respect for the role at the expense of own identity. The clinical case of Jonas highlights a conceptual bridge between the model of melancholia as loss of social role and the model of melancholia as desynchronization. [less ▲]

The daily intakes (DI) were estimated in a Belgian general population for 5 phthalates, namely diethyl phthalate (DEP), di-n-butyl phthalate (DnBP), di-iso-butyl phthalate (DiBP), butylbenzyl phthalate (BBzP) and di-2-ethylhexyl phthalate (DEHP), based on the urinary measurements of their corresponding metabolites. DI values ranged between <LOD and 59.65 μg/kg bw/day depending on the congener, and were globally higher for children than adults. They were compared to acceptable levels of exposure (tolerable daily intakes) to evaluate the hazard quotients (HQ), which highlight an intake above the dose considered as safe for values greater than 1. If very few of our Belgian participants exceeded this threshold for phthalates considered individually, 6.2% of the adults and 25% of the children showed an excessive hazard index (HI) which took into account the cumulative risk of adverse anti-androgenic effects. These results are of concern since these HI were based on only 3 phthalates (DEHP, DiBP and DnBP), and showed a median of 0.55 and 0.29 for children and adults respectively. The comparison with previously determined dietary intakes demonstrated that for DEHP, food intake was nearly the only route of exposure while other pathways occurred mainly for the other studied phthalates.

The purpose of this work is to propose an enhancement of Doblaré and García's internal bone remodelling model based on the continuum damage mechanics theory. In their paper, they stated that the evolution of the internal variables of the bone microstructure, and its incidence on the modification of the elastic constitutive parameters, may be formulated following the principles of Continuum Damage Mechanics, although no actual damage was considered. The resorption and apposition criteria (similar to the damage criterion) were expressed in terms of a mechanical stimulus. However, the resorption criterion is lacking a dimensional consistency with the remodelling rate. We here propose an enhancement to this resorption criterion, insuring the dimensional consistency while retaining the physical properties of the original remodelling model. We then analyse the change in the resorption criterion hypersurface in the stress space for a 2D analysis. We finally apply the new formulation to analyse the structural evolution of a 2D femur. This analysis gives results consistent with the original model but with a faster and more stable convergence rate. [less ▲]

Auteur, historiographe mais aussi lieutenant des troupes pontificales lors de la Ligue de Cognac et, donc, acteur de l’histoire en train de se jouer, Francesco Guicciardini est en prise directe avec les événements ; dans sa volumineuse correspondance se mêlent petite et grande Histoire. Or, si le substantif et l’adjectif « contemporaneo » existent en italien depuis Dante au moins, Guicciardini n’en fait l’usage ni dans ses œuvres, ni dans ses lettres qui ne comptent aucune occurrence du terme. Partant de ce constat, je me propose, dans mon article, de relever et d’analyser le langage utilisé par Guicciardini pour nommer le moment auquel il vit, en cerner les contours et la façon dont celui-ci se distingue de ce qui précède pour former un moment à part : les expressions qui disent le présent (tempo presente/tempi presenti, questi tempi, medesimi tempi) et celles qui le caractérisent (conditione de' tempi, extraordinario, tempi strani) ou qui expriment le moyen de l’affronter (remedii conformi a’ tempi) seront, dès lors, au centre de mon attention.

Scientists in many fields of research have developed models, theories and concepts attempting to grasp and manage dangers that are often difficult to imagine. Among the different perspectives, the Science and Technology Studies (STS) Vulnerability Approach seems very promising. Relying on a constructivist paradigm, it is based on an inductive collection and analysis of a wide range of factors, with a particular focus on cultural factors and actual day-to-day practices. In this paper, we present the roots of this approach and we display findings based on three case studies exploring emergency planning in three different contexts (a city near a SEVESO plant, a school near a nuclear plant, and a city confronted to multiple catastrophic scenarios). The cases studies were realized by conducting three Focus Groups with different types of stakeholders (citizens, teachers, firemen, decision makers, etc.). After presenting the results of the case studies, we discuss how stakeholders’ participation can inform such type of vulnerability analysis in the context of emergency planning. We argue that participation fosters a deep understanding of actual safety governance practices which allows innovative results to emerge as well as it initiates a learning process among the participants. It contributes to questioning the relations between decision-makers, experts and citizens. It has the potential of bypassing the positivist and quantitative rationale of safety, and thus, of redefining the vulnerability governance. As a conclusion, we question the role of such STS vulnerability approach within the actual vulnerability governance. [less ▲]

Despite a rapid growth and an ongoing need for outplacement services, little is yet known about the perceived adequacy and benefits of these services for redundant employees using them. We surveyed 360 Belgian redundant employees (i.e., clients) using outplacement services provided by a public employment agency. The results indicate that an outplacement experience perceived as adequate for clients fosters their overall impressions of justice towards the dismissing organization; this leads in turn to benefits for them: reduction of negative emotions, enhancement of their perceived well-being, future perspectives, and job-seeking activities - confirming the mediating role of overall justice.

« Savourer la nourriture et respirer la culture marocaine deviennent une expérience et une émotion unique, à découvrir et à vivre grâce à la combinaison d’arômes, goûts, couleurs, formes et musiques ». Au travers de ce slogan, un renommé restaurant d’inspiration marocaine de la ville de Milan en Italie, invitait ses clients à voyager au travers de leur sensorialité dans une culture alimentaire (et par synecdoque, une culture tout court) autre. Le goût les aurait amenés à expérimenter un exotisme, qui était néanmoins contrôlé, car certaines conditions imposées par les normes locales faisaient en sorte que le déplacement vécu ne fût pas excessivement déstabilisant. Le résultat de ces négociations consistait d’un menu qui accostait les gastronomies marocaine et italienne (ou les procédures de l’une et de l’autre) dans certains plats décrits comme « fusion », qui satisfaisaient (ou non) les exigences des clients. Dans cet article, je vise à mettre en évidence les mécanismes de production discursive et matérielle de ces plats, ainsi comme les opinions des consommateurs. Pour ce faire, j’analyserai le matériel ethnographique collecté auprès du local en question en le comparant avec les pratiques observés dans d’autres restaurants milanais. En ce qui concerne les effets obtenus, j’appuierait mon analyse sur une plateforme de médias sociaux consacrée aux recensions d’endroits et locaux touristiques. La culture alimentaire sera étudiée dans ses aspects symboliques mais aussi matériels, en faisant également recours au matériel visuel récolté. [less ▲]

Cet article expose le développement d’une méthodologie automatique pour la détection des changements du bâti en vue d'une mise à jour semi automatique des cartes urbaines. L'approche est basée sur la comparaison entre une carte existante et une image à très haute résolution spatiale (THRS) récente. Elle s'enchaine sur 4 étapes. D'abord l'image est segmentée pour produire des primitives. Ces dernières sont caractérisées par 4 catégories d'attributs. Des classifieurs avancés par apprentissage supervisé (CAAS) ont été utilisés dans l'étape de la classification. Le paramétrage optimal de ces classifieurs est obtenu automatiquement par validation croisée en se référant au meilleur taux d'erreur. La prédiction finale des objets est déduite par un combineur de multiples classifieurs (CMC) conçu à partir des 3 meilleurs CAAS. Enfin, une étape de détection des changements permet d'identifier les primitives qui représentent les changements du bâti. Les données utilisées concernent la ville de Rabat (Maroc). Une image QuickBird a été utilisée avec un plan existant à l'échelle 1:10,000. Indépendamment de la qualité de la forme des bâtiments détectés, la méthode offre des meilleurs taux en exhaustivité (91.7%) et en exactitude (81.5%). [less ▲]

The influence of substrate hydrophobicity and biomacromolecules (dextran, bovine serum albumin - BSA) adsorption on the cleanability of surfaces soiled by spraying aqueous suspensions of quartz particles (10 to 30 µm size), then dried, was investigated using glass and polystyrene as substrates. The cleanability was evaluated using radial flow cell (RFC). The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The interpretation of XPS data allowed the complexity due to the ubiquitous presence of organic contaminants to be coped with, and the surface composition to be expressed in terms of both the amount of adlayer and the mass concentration of adlayer constituents. When soiled with a suspension of particles in water, glass was much less cleanable than polystyrene, which was attributed to its much lower water contact angle, in agreement with previous observations on starch soil. Dextran was easily desorbed and did not affect the cleanability. The presence of BSA at the interface strongly improved the cleanability of glass while the contact angle did not change appreciably. In contrast, soiling polystyrene with quartz particles suspended in a BSA solution instead of water did not change markedly the cleanability, while the contact angle was much lower and the aggregates of soiling particles were more flat. These observations are explained by the major role of capillary forces developed upon drying, which influence the closeness of the contact between the soiling particles and the substrate and, thereby, the adherence of particles. The capillary forces are proportional to the liquid surface tension and depend in a more complex way on contact angles of the particles and of the substrate. The dependence of cleanability on capillary forces, and in particular on the liquid surface tension, is predominant as compared with its dependence on the size and shape of the soiling aggregates, which influence the efficiency of shear forces exerted by the flowing water upon cleaning.

This work presents development of statistical shape models based on robust and rigid-groupwise registration followed by pointset non-rigid registration. The main advantages of the pipeline include automation in that the method does not rely on manual landmarks or a regionalization step; there is no bias in the choice of reference during the correspondence steps and the use of the Probabilistic Principal Component Analysis framework increases the domain of the shape variability. A comparison between the widely used Expectation Maximization- Iterative Closest Point algorithm and a recently reported groupwise method on publicly available data (hippocampus) using the well-known criteria of generality, specificity and compactness is also presented. The proposed method gives similar values but the curves of generality and specificity are superior to those of the other two methods. Finally the method is applied to the human scapula, which is a known difficult structure, and the human humerus. [less ▲]

Background: Inflammatory airway disease (IAD) affects performance and well-being in horses. Diagnosis is primarily reached by bronchoalveolar lavage (BAL) cytology but this is invasive and requires sedation. Objectives: The purpose of this study was to identify candidate blood biomarkers of IAD using species-specific expression microarrays. Methods: Horse Gene Expression Microarrays were used to investigate global mRNA expression in circulating leukocytes from healthy and IAD-affected standardbreds and endurance horses. Results: Nine genes were significantly differentially regulated in standardbreds and 61 in endurance horses (P < 0.001). These genes were mainly related to inflammation (eg. ALOX15B, PLA2G12B and PENK), oxidant/antioxidant balance (eg. DUOXA2 and GSTO1-1) and stress (eg. V1aR, GRLF1, Homer-2 and MAOB). DUOXA2, ALOX15B, PLA2G12B, MAOB and GRLF1 variations of expression were further validated by RT-qPCR. The deregulation of the oxidant/antioxidant balance was demonstrated at the protein level by an increase of glutathione peroxidase (GPx) activity in heparinised whole blood of IAD-affected standardbreds (P = 0.0025) and endurance horses (P = 0.0028). There was good correlation (r = 0.7354) between BAL neutrophil percentage and whole blood GPx activity in all horses. Conclusions: There is accumulating evidence that, even when systemic clinical signs are not evident, circulating leukocyte gene expression can reflect responses of other tissues, leading to potential diagnostic applications in the future. Although not specific for IAD, whole blood GPx activity appears to reflect BAL neutrophil percentage. This finding should be further assessed by testing a larger number of horses. [less ▲]

Background/Aims: Heroin-assisted treatment (HAT) can improve the condition of heroin addicts still using street heroin after a methadone treatment. In Belgium, a new trial compared the efficacy of a HAT to existing methadone maintenance treatment. Methods: In this randomised controlled trial, HAT was limited to 12 months. Participants were assessed every 3 months. They were responders if they showed improvement on the level of street heroin use, health or criminal involvement. Results: 74 participants were randomised in the trial. The experimental group (n=36) counted 30% of responders more than the control group (n=38) at each assessment point (p<0.05), except at 12 months where the difference (11%) was no longer significant (p=0.35). Still, after 12 months, participants in the experimental group reported significantly greater improvements (p<0.05) than the control group on the level of street heroin use and on the level of physical and mental health. Both groups reported significantly less criminal facts after 12 months (p<0.001), but with no significant difference between the groups. Conclusions: This trial confirms the short-term efficacy of HAT for severe heroin addicts, who already failed methadone treatment. [less ▲]

The aphid–ant mutualistic relationships are not necessarily obligate for neither partners but evidence is that such interactions provide them strong advantages in terms of global fitness. While it is largely assumed that ants actively search for their mutualistic partners namely using volatile cues; whether winged aphids (i.e. aphids’ most mobile form) are able to select ant-frequented areas had not been investigated so far. Ant-frequented sites would indeed offer several advantages for these aphids including a lower predation pressure through ant presence and enhanced chances of establishing mutuaslistic interactions with neighbour ant colonies. In the field, aphid colonies are often observed in higher densities around ant nests, which is probably linked to a better survival ensured by ants’ services. Nevertheless, this could also result from a preferential establishment of winged aphids in ant-frequented areas. We tested this last hypothesis through different ethological assays and show that the facultative myrmecophilous black bean aphid, Aphis fabae L., does not orientate its search for a host plant preferentially towards ant-frequented plants. However our results suggest that ants reduce the number of winged aphids leaving the newly colonized plant. Thus, ants involved in facultative myrmecophilous interactions with aphids appear to contribute to structure aphid populations in the field by ensuring a better establishment and survival of newly established colonies rather than by inducing a deliberate plant selection by aphid partners based on the proximity of ant colonies.

BACKGROUND: Signals of an increased risk of myocardial infarction (MI) have been identified with dabigatran etexilate in randomized controlled trials (RCTs). METHODS AND RESULES: We conducted searches of the published literature and a clinical trials registry maintained by the drug manufacturer. Criteria for inclusion in our meta-analysis included all RCTs and the availability of outcome data for MI, other cardiovascular events, major bleeding, and all-cause mortality. Among the 501 unique references identified, 14 RCTs fulfilled the inclusion criteria. Stratification analyses by comparators and doses of dabigatran etexilate were conducted. Peto odds ratio (ORPETO) values using the fixed-effect model (FEM) for MI, other cardiovascular events, major bleeding, and all-cause mortality were 1.34 (95% CI 1.08 to 1.65, P=0.007), 0.93 (95%CI 0.83 to 1.06, P=0.270), 0.88 (95% CI 0.79 to 0.99, P=0.029), and 0.89 (95% CI 0.80 to 1.00, P=0.041). When compared with warfarin, ORPETO values using FEM were 1.41 (95% CI 1.11 to 1.80, P=0.005), 0.94 (95%CI 0.83 to 1.06, P=0.293), 0.85 (95% CI 0.76 to 0.96, P=0.007), and 0.90 (95% CI 0.81 to 1.01, P=0.061), respectively. In RCTs using the 150-mg BID dosage, the ORPETO values using FEM were 1.45 (95% CI 1.11 to 1.91, P=0.007), 0.95 (95% CI 0.82 to 1.09, P=0.423), 0.92 (95% CI 0.81 to 1.05, P=0.228), and 0.88 (95% CI 0.78 to 1.00, P=0.045), respectively. The results of the 110-mg BID dosage were mainly driven by the RE-LY trial. CONCLUSIONS: This meta-analysis provides evidence that dabigatran etexilate is associated with a significantly increased risk of MI. This increased risk should be considered taking into account the overall benefit in terms of major bleeding and all-cause mortality. [less ▲]

Purpose. The purpose of this study is to examine the effect of institutional investors ownership and activism on information asymmetry and stock market liquidity in France. Design/methodology/approach. Our sample includes 162 French-listed firms over a period ranging from 2007 to 2009. Our methodology relies on linear regressions using the method of ordinary least square(OLS). Befor examining the interaction between liquidity and institutional investors, we check for the existence of the endogeneity problem by applying the Durbin-Wu_Hausman test of Davidson and MacKinnon (1993). The results of the endogeneity test show that institutional investor ownership and stock liquidity are endogenous. A simultaneous equation model using the second least square method is then tested to address this problem. Findings The findings show that the proportion of institutional investors has a positive and significant effect on stock-market liquidity, which confirms the signal theory and trading hypothesis. These investors perform high trading activity which favourably affect market liquidity. The results suggests that pension funds manage huge assets decreasing transaction costs and improving liquidity. They display a positive signal to the market about more transparency and a low level of information asymmetry.These results highlight the institutional investors'role in defining the level of liquidity of assets on the French market. Our findings also stress the importance of developing institutional investors'demand for the Paris market in order to better assess firms'values, protect minority ownership and improve market liquidity. Originality/Value In the French institutional setting, institutional investors act as a control device since minority shareholder interests are less protected than in Anglo-American counterparts. This result highlights the significant rôle of institional investors in corporate governance structures and a finacila markets. Their prsence is a guarantee for minority interest protection and for improving market liquidity. [less ▲]

Les ouvrages de Frédéric Lordon ont offert ces dernières années un éclairage nouveau des mécanismes de la finance et du capitalisme en régime néolibéral, en vertu de la place centrale qu’ils accordent aux affects. Il est frappant que cette entreprise – qui est triple: analyse de la finance, analyse du capitalisme, analyse de la domination – soit doublée d’une attention portée au discours même qui la développe. On peut repérer une telle attention dans la pluralité des genres de discours qu’investit Frédéric Lordon : ouvrages « savants » ou « universitaires », mais aussi courts essais engagés aux éditions Raisons d’agir, articles de presse dans Le Monde Diplomatique notamment, tenue du blog « La pompe à phynance » sur le site du même journal, et même pièce de théâtre récemment adaptée au cinéma, D’un retournement l’autre. Comédie sérieuse sur la crise financière. En quatre actes, et en alexandrins . Diversité de genre entre les différents types de textes, donc. Diversité interne à chacun de ces textes, aussi : le lecteur de Frédéric Lordon se trouve toujours à cheval sur plusieurs codes rhétoriques dont joue l’auteur dans un même ouvrage. On pourrait bien sûr tenir cette double diversité pour la simple conséquence du talent d’écriture de Lordon, ou d’un plaisir pris par l’auteur à jouer du langage et des ethos qu’il construit. Le présent article propose au contraire de considérer cette diversité comme le résultat d’un véritable travail sur les modalités rhétoriques du discours critique sur le capitalisme financiarisé, qu’il faut articuler aux principaux postulats de sa théorie sociale. L’hypothèse défendue sera, précisément, de considérer qu’il y a une construction rhétorique qui participe de l’entreprise critique et, du même coup, qui s’inscrit comme un geste politique dans une « société des affects ».

This paper presents a formalism for the transient simulation of nonsmooth dynamic mechanical systems composed of rigid and flexible bodies, kinematic joints and frictionless contact conditions. The proposed algorithm guarantees the exact satisfaction of the bilateral and unilateral constraints both at position and velocity levels. Thus, it significantly differs from penalty techniques since no penetration is allowed. The numerical scheme is obtained in two main steps. Firstly, a splitting method is used to isolate the contributions of impacts, which shall be integrated with only first-order accuracy, from smooth contributions which can be integrated using a higher order scheme. Secondly, following the idea of Gear, Gupta and Leimkuhler, the equations of motion are reformulated so that the bilateral and unilateral constraints appear both at position and velocity levels. After time discretization, the equations of motion involve two complementarity conditions and it can be solved at each time step using a monolithic semi-smooth Newton method. The numerical behaviour of the proposed method is studied and compared to other approaches for a number of numerical examples. It is shown that the formulation offers a unified and valid approach for the description of contact conditions between rigid bodies as well as between flexible bodies. [less ▲]

The strength of thin-walled stainless steel columns has been investigated extensively over the past few years. In European standards, the concept of section classification for determining the cross-section capacity is used. In this system, for Class 4 cross-sections, the Effective Width Method (EWM) must be used to account for the effect of local buckling. Because of the complexity and limitations of this method, other methods have been developed, such as the Direct Strength Method (DSM) for cold-formed thin-walled profiles and the Continuous Strength Method (CSM), initially established for members made of nonlinear metallic materials. In the CSM, to take advantage of strain hardening, a deformation-based design approach employing a continuous relationship between the cross-sectional slenderness and the cross-sectional deformation capacity is used. To a large extent, the CSM yield accurate predictions, especially in the low slenderness range where the current DSM design procedures for members submitted to pure compression tends to produce conservative predictions, for materials with pronounced strain hardening such as stainless steel alloys. The present paper presents an extension of the traditional DSM which provides accurate design strength predictions in the low slenderness range for stainless steel thin-walled section columns failing by distortional, local and overall buckling. It contains practical information concerning the reference experimental data and draws conclusions about the justification of the proposed analytical formula. The paper is divided into three main parts: the description of the database, the establishment of the design model and a reliability analysis of the method. [less ▲]

Besides being known for population overcrowding, prison staff strikes, and prisoner suicides or escapes, which are frequently reported by the press, prison might also be a place for rare innovative projects. One such project can be seen in a penitentiary policy initiated in Belgium in 2000 aimed at re-shaping the culture of detention towards a culture of ‘restorative justice’. What can be said of this attempt at introducing the concepts of victim, restoration, responsibilization, sensitizing and awareness within prison walls? The present article proposes an illustrative and interpretive account of this prison policy. Rather than restoring the broken victim-offender relationship, its implementation has something to do with detainees working on their ‘self’. [less ▲]

The pre-eminence of the realistic conception has long locked the field of study of the power in International Relations, which is nowadays highly questioned. The analysis of some “new powers” emergence is as such a tremendous learning experience. In order to go beyond the classical antagonism between the institutional perspectives (cooperation) and the realistic ones (rivalry), this paper deals with the power in an alternative way, from a heterodox approach of hegemony, which allows us to make out the phenomena of insidious and not felt so domination. Following the example of China, committed to building a status of world power, sustained by a self-legitimizing discourse abounding with Third-World overtones (anti-hegemonism, multipolarization of the world, South-South cooperation, etc.), the increase in its global influence does not only depend on the availability of its – tangible and intangible – resources, nor on its ability to mobilize them adequately (smart power). China also values the image that it has of itself (self-perception), the image that it tends to convey on the international stage (representation), as well as the perception of its status by the other actors of the international system (external recognition). The power of China is measured through its capacity to “assert itself as a reference” for its emerging peers, or even for Western powers. [less ▲]

Age-related changes in intestinal flora and host defences, the receipt of antibiotic treatment, and the presence of underlying diseases are some of the most common risk factors associated with Clostridium difficile infection. Therefore, retirement care facilities for elderly people have been pinpointed as frequent sources of contamination. There is only limited data regarding the presence and epidemiology of C. difficile in nursing homes, and this gap in the current literature emphasises the need to gain a better understanding of the situation in order to prevent the emergence of new outbreaks among this population group.
