International audienceError concealment (EC) is one of the target applications of inpainting techniques. Some methods combine the estimated lost motion vectors (MVs) with the exemplar-based inpainting technique to recover the lost regions. Due to the erroneous motion vectors that might indicate a moving object as background object and vice versa, these methods are still showing visual artifacts in the recovered regions. In this paper, a concept of motion map that can be easily generated in the decoder side is introduced and it is combined with the exemplar-based inpainting technique. The proposed method introduces an adaptive search window size that trades-off the quality and complexity. Moreover, an optional blending technique is proposed to limit the spatio-temporal artifacts. Experiments show that the proposed method improves the visual quality with 5dB on average relative to the state-of-the-art inpainting-based EC method

L’histoire toute crue : la Première Croisade au miroir de son Histoire

L’essence pure du récit tel qu’on peut idéalement le concevoir, c’est l’histoire toute crue, la série intacte des événements tels qu’ils sont apparus dans le monde, fût-il fictif, avant que ne vienne s’en emparer la parole du narrateur. Gérard Genette, Figures II, Paris, 1972, p. 63. L’Histoire des Croisades ne s’est jamais aussi bien portée, en particulier dans les pays anglo-saxons : on ne compte plus les « Histoires », « Histoires Brèves », « Nouvelles Histoires » des Croisades, qui toutes..

Entre Moyen Âge et Renaissance ? L’Angleterre vers 1500

S’il fallait attribuer quelque utilité au vocabulaire de la périodisation, ce serait comme répertoire de métonymies pour désigner la circulation des influences culturelles, leurs modes de diffusion, leurs effets et la rapidité de ces mouvements. Or la périodisation ne remplit généralement pas cette fonction d’évocation du tout par un seul élément. Il s’agit le plus souvent d’un jeu de catégories exclusivement chronologiques imposé à un ensemble de pratiques culturelles, et qu’il serait plus j..

Composing individuals: ethnographic reflections on success and prestige in the British New Music Network

In contrast to established musicians, lesser-known composers have received scant attention in art music scholarship. This article, based on an ethnographic study, considers how a group of British composers construed ideas of success and prestige, which I analyse in terms of anthropological writings on exchange, Bourdieusian symbolic economies, and Foucauldian notions of disciplinary power. Prestige was ascribed to composers who created ‘interesting’ music, a category that eclipsed novelty as an aim. Individuality, enacted within a context of individualism, was key to assessing whether music was interesting. This individuality had to be tempered, structured, and embedded in the social norms of this and related ‘art worlds’. The article examines the social processes involved in creating this individuality, musical personality, and music considered interesting

Transition outcomes for young people discharged from adolescent medium secure services in England : a qualitative study exploring adolescents' and carers' experiences

Background: Young people in secure services present with multiple vulnerabilities, therefore transition periods are especially challenging for this group. In this study we followed up young people discharged from adolescent medium secure services to adult and community settings with the aim to explore transition experiences and outcomes. Methods: Participants were recruited from 15 child and adult mental health services in England. We conducted qualitative semi-structured interviews with 13 young people, aged 18 -19 years, moving from child and adolescent medium secure units two to six months post-transition, and five carers one to three months pre-transition. Thematic analysis was performed to identify predetermined or data-driven themes elicited from face-to-face interviews. Results: The findings indicated poor transition outcomes for young people with the most severe mental health symptoms and those who committed serious offences. Three overarching themes were identified: (1) unsettling environmental factors within adult services; (2) experiences of transition management and preparation; and (3) parental experiences of transition process and engagement with adult services. Conclusion: The findings of this study indicate that young people and carers value ongoing involvement in the transition process by well-informed parallel care. They also highlight the need for a national integrative care model that diverges from the traditional ‘one-size-fits-all’ approach

Do changes to the local street environment alter behaviour and quality of life of older adults? The ‘DIY Streets’ intervention

<p>Background: The burden of ill-health due to inactivity has recently been highlighted. Better studies on environments that support physical activity are called for, including longitudinal studies of environmental interventions. A programme of residential street improvements in the UK (Sustrans ‘DIY Streets’) allowed a rare opportunity for a prospective, longitudinal study of the effect of such changes on older adults’ activities, health and quality of life.</p> <p>Methods: Pre–post, cross-sectional surveys were carried out in locations across England, Wales and Scotland; participants were aged 65+ living in intervention or comparison streets. A questionnaire covered health and quality of life, frequency of outdoor trips, time outdoors in different activities and a 38-item scale on neighbourhood open space. A cohort study explored changes in self-report activity and well-being postintervention. Activity levels were also measured by accelerometer and accompanying diary records.</p> <p>Results: The cross-sectional surveys showed outdoor activity predicted by having a clean, nuisance-free local park, attractive, barrier-free routes to it and other natural environments nearby. Being able to park one's car outside the house also predicted time outdoors. The environmental changes had an impact on perceptions of street walkability and safety at night, but not on overall activity levels, health or quality of life. Participants’ moderate-to-vigorous activity levels rarely met UK health recommendations.</p> <p>Conclusions: Our study contributes to methodology in a longitudinal, pre–post design and points to factors in the built environment that support active ageing. We include an example of knowledge exchange guidance on age-friendly built environments for policy-makers and planners.</p&gt

Physical activity mass media campaigns and their evaluation: a systematic review of the literature 2003–2010

Internationally, mass media campaigns to promote regular moderate-intensity physical activity have increased recently. Evidence of mass media campaign effectiveness exists in other health areas, however the evidence for physical activity is limited. The purpose was to systematically review the literature on physical activity mass media campaigns, 2003–2010. A focus was on reviewing evaluation designs, theory used, formative evaluation, campaign effects and outcomes. Literature was searched resulting in 18 individual adult mass media campaigns, mostly in high-income regions and two in middle-income regions. Designs included: quasi experimental (n = 5); non experimental (n = 12); a mixed methods design (n = 1). One half used formative research. Awareness levels ranged from 17 to 95%. Seven campaigns reported significant increases in physical activity levels. The review found that beyond awareness raising, changes in other outcomes were measured, assessed but reported in varying ways. It highlighted improvements in evaluation, although limited evidence of campaign effects remain. It provides an update on the evaluation methodologies used in the adult literature. We recommend optimal evaluation design should include: (1) formative research to inform theories/frameworks, campaign content and evaluation design; (2) cohort study design with multiple data collection points; (3) sufficient duration; (4) use of validated measures; (5) sufficient evaluation resources
