[more ▼]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. Des protos-photogrammes et de leur usage scientifique chez Muybridge et Marey, aux usages artistiques contemporains, en passant par des pratiques publicitaires, promotionnelles ou analytiques, nous allons voir que le photogramme reste un objet singulier.

[more ▼]We study retirement incentives with an augmented reduced form option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples’ incentives leads to very different patterns of retirement incentives – particularly for women. We apply the new indicators to data from the Survey of Health, Ageing and retirement in Europe (SHARE) in Belgium and find two key results. First, contrary to several previous studies, we obtain a positive signed income effects. Second, we find very different retirement incentives for men and women, with little flexibility in the retirement decision for men and substantially more flexibility for women as a function of financial incentive and household composition.

[more ▼]This paper uses institutional theory to highlight different patterns of cross-sector collaboration from the perspective of social enterprises. Specifically, it explores how and why social enterprises interact with mainstream businesses and to what extent their collaboration patterns reflect a vision of how their social mission should be implemented and institutionalized. The empirical analysis is derived from a qualitative study of ‘fair trade’ – a hybrid model created by social enterprises and using market mechanisms to support small-scale producers in developing countries and to advocate for changes in international trading practices. The findings highlight three strategies used by fair trade social enterprises to manage their interactions with mainstream businesses: sector solidarity, selective engagement, and active appropriation. This paper suggests that each strategy is motivated by a different vision of how best to articulate the social mission of fair trade via specific types of collaborations. It also notes how each vision has a distinct pattern of institutionalization at the field level. This paper adds to the emergent literatures on social enterprise and social entrepreneurship, fair trade, cross-sector collaboration and hybrid organizing.

[more ▼]Supplementation of post-weaning diets with exogenous enzymes has been suggested to control post-weaning syndrome, by compensating for the under-developed endogenous enzyme secretory capacity and increasing nutrient digestibility in newly weaned pigs. The effect of in-feed enzymes in improving gut maturation, growth and/or health in weaned piglets is not always consistent. A systematic review and a meta-analysis were therefore conducted to determine which exogenous enzymes are most consistent in improving piglet growth and digestibility when supplemented to post-weaning diets. The mean difference effect of enzyme supplementation on growth and digestibility of dry matter (DM), gross energy (GE), crude protein (CP), and P digestibility was calculated for each study and this was used as the effect size estimate in the meta-analysis. The impact of feed enzyme supplementation on intestinal health and bone mineralization was also discussed where information was available in the literature. From a total of 90 studies included in the metaanalysis, G:F was improved in 55, remained un-changed in 28 and deteriorated in 7, in response to enzyme supplementation. Average daily gain, average daily feed intake (ADFI) and G:F was improved when phytase was supplemented in the diet. Phosphorous digestibility was increased with phytase supplementation while GE digestibility was reduced. Dietary phytase supplementation increased bone mineralization in pigs fed diets with a reduced Pcontent. Supplementation with multi-enzyme complexes increased DM and CP digestibility. In conclusion, the most consistent improvement in piglet growth, P digestibility and bone mineralization were found due to exogenous phytase supplementation. Supplementation with xylanase alone or in combination with β-glucanase had inconsistent effects on piglet growth and nutrient digestibility. The most consistent improvements in growth and nutrient digestibility due to supplementation with multi-enzymes complexes were found when mannanase and/or protease were included in the complex.

[more ▼]In the last two decades, wavelet bases and associated methodologies have become quite important in many domains, such as signal and image processing, harmonic analysis, statistics, and so on. More recently, they also turn out to be quite useful in the probabilistic framework of stochastic processes, in which, among other things, they allow to obtain fine results concerning erratic sample paths behavior. The goal of our article is to derive a result, related with zeros of continuous compactly supported mother wavelets, which is useful in this probabilistic framework. More precisely, let $\psi$ be any arbitrary such wavelet; we show that being given an arbitrary point $x_0\in\R$ there always exists at least one integer $k_{x_0}\in\Z$ such that $\psi(x_0-k_{x_0}) \neq 0$.

[more ▼]In recent years, inclusive design (a.k.a. universal design or design for all) is one of the developed approaches which aim to consider the diverse human abilities and conditions in the design process. As defined by the European Institute for Design and Disability (EIDD) ‘design for all’ is designing for diversity, social inclusion and equality. Considering the social and demographic changes in the 21st century, which include an international movement towards social inclusion and more specifically the rights of disabled people, an inclusive approach is turning into a necessity for today’s diverse and ageing society. In the case of architectural and urban heritage, the disabled people or in better words those with diverse sensory, mental or mobility abilities who differ from the general public, have the right to experience, interact with, and engage with heritage and its values. As part of an extensive interdisciplinary research on inclusive approaches to built heritage values, which connects the fields of architecture, history, conservation, inclusive design, and digital humanities, this paper investigates the potentials of incorporating digital tools and techniques in the different aspects of this research. The extensive study involves communication between researchers, relevant professional experts, and the historic built environment with the target community of disabled people and in this paper, the digital means to facilitate these interactions have been studied. As a step towards answering the question ‘what are suitable methods and tools for facilitating and acquiring insight into diversely abled people’s engagement with and understanding of architectural heritage and its values?’, it more specifically focuses on the interaction of the disabled people with the historic architecture and urban spaces. Additionally, in a more general approach, by linking the fields of digital humanities and architectural research, the existing tools for the different stages of research ranging from data collection and storage, data analysis, and dissemination are explored. By conducting and elaborating relevant research examples, this study shows how incorporating digital tools and techniques derived from Digital Humanities - such as retrieving data through APIs, textual analysis, creating and querying databases, and data visualization - can facilitate research in the field of architecture and built heritage. Moreover, in studying the relation between disability and the historic built environment, it indicates that acquiring knowledge on the potentials in practical digital tools for disabled people’s interaction with the built heritage, can have a significant impact on the research approach and findings. As for an inclusive approach to built heritage, the disabled people can be taken into account with their prospective extended digital abilities. Hence in today’s digital world, integrating the digital tools and technologies in architectural heritage research is not only a necessary practical mean for conducting research, but can also impact the theoretical approach, allowing to carry out extensive and innovative research in an efficient manner.

[more ▼]A linear oscillator simultaneously subjected to stochastic forcing and parametric excitation is considered. The time required for this system to evolve from a low initial energy level until a higher energy state for the first time is a random variable. Its expectation satisfies the Pontryagin equation of the problem, which is solved with the asymptotic expansion method developed by Khasminskii. This allowed deriving closed-form expressions for the expected first passage time. A comprehensive parameter analysis of these solutions is performed. Beside identifying the important dimensionless groups governing the problem, it also highlights three important regimes which are called incubation, multiplicative and additive because of their specific features. Those three regimes are discussed with the parameters of the problem. [less ▲]Detailed reference viewed: 54 (17 ULg)
