Ever since car ownership and car use started to increase in Western Europe and the USA, transportation planners attempted to model people’s travel behavior. In the context of the Feathers project a dynamic activity-based travel demand framework is developed for Flanders. In this paper, the complete survey design of the data collection effort required for such dynamic activity-based model is discussed. A mixed survey design of using a PDA application on the one hand, and using traditional paper and pencil diaries on the other hand, turns out to be a very suitable way of collecting detailed information about planned and executed activity-travel behavior of households. The results show that no attrition effects are present, not on the number of out-of-home activities reported, nor on the number of trips reported. Moreover the survey mode (PDA versus paper and pencil) has no direct impact on the quantities investigated. Notwithstanding, it is essential for further analysis on the Feathers data to explicitly take into account mode effects because of two reasons. First, the effect of explanatory variables can be influenced by the survey mode. Second, the variance in the estimation of the quantity investigated can differ significantly. Heteroscedatisc linear regression models provide the required framework to explicitly take into account these mode effects. [less ▲]

L’agriculture familiale africaine est concernée directement par l’Objectif 1 du Millénaire pour le Développement, de réduire de moitié d’ici 2015 l’extrême pauvreté et la faim. En effet, selon la plupart des observateurs, 70% des pauvres sont localisés dans les zones rurales et sont agriculteurs. Dans ce contexte, il importe de s’interroger sur l’avenir des exploitations agricoles familiales en Afrique. Après avoir présenté la problématique générale de l’exploitation agricole familiale dans le développement, les auteurs présentent une analyse au départ des constats qu’ils ont pu réaliser, respectivement pour les filières de rente de la zone forestière au Cameroun et pour le coton, dans plusieurs pays d’Afrique de l’Ouest. Les analyses sont réalisées à partir des observations effectuées au départ de différentes études financées essentiellement par la Commission européenne au cours de ces dernières années. Il en résulte que le terme « agriculture familiale » recouvre des réalités très différentes avec une différenciation de plus en plus poussée des exploitations agricoles. Dans le même temps, il subsiste de nombreuses exploitations familiales plus « traditionnelles » mêlant des logiques d’autoconsommation et de marché avec des dotations en facteurs plus inégales et donc plus vulnérables. L’enjeu primordial des politiques agricoles qui seront définies sera précisément de prendre en considération la dimension spécifique de ce type d’exploitation, cible prioritaire dans la lutte contre la pauvreté. L’orientation des politiques mises en œuvre autour du seul objectif de la production de biens agricoles ne permettra pas de réduire les disparités internes et souvent croissantes observées. Il convient donc d’intégrer les dimensions sociales et environnementales dans les objectifs des politiques agricoles à mettre en œuvre. [less ▲]

Behavioural and psychological signs and symptoms - BPSD are clinical features of dementia. They have considerable impact on the daily life of patients and their caregivers. The aim of this study is to show the importance of these disorders in dementia semiology and to assess differences in their prevalence across levels of severity of dementia. The sample is made up of 160 subjects with dementia older than 65 years old. Diagnosis of dementia was based on DSM-IV criteria. BPSD were assessed with the NeuroPsychiatric Inventory-NPI and dementia staging was measured with Clinical Dementia Rating/Modified-CDR-M. Results show that prevalence of delusions is more important in severe dementia and that prevalence of agitation/ aggression is more important in profound dementia. These data may help to clarify objectives and treatment of BPSD. This study raises also some methodological problems with the NPI and underlines the importance to define the different disorders included in certain NPI domains accurately. [less ▲]

This study approaches the question of the evolution of the quality of life (QOL) measures in older patient populations. On base of the report of the weak number of instruments specifically adapted to this population and of the absence of instruments taking into account both the expectations and the priorities of the individuals, we wished to make the adaptation of a tool for adult, the Quality of life Systematic Inventory (QLSI©). In this prospect, the main aim of this preliminary research was to test the evaluative approach of the QLSI© within a population of old people and to obtain useful information for the construction of a version of the QLSI© for old people. 135 voluntary subjects, from 65 to 85 years old, living at home and having a good health participated in the study. The questionnaire revealed a good QOL which could be explained by the combination of diverse factors such as a good current situation, a lesser importance given to the diverse life domains and the relatively weak goals. The results demonstrated the relevance of the QLSI© but also showed the necessity of certain modifications to make this questionnaire more specific to the old person. [less ▲]

À travers l’étude de deux extraits des Vies de Plutarque (Thémistocle, 13 et Antoine, 24), faisant tous deux apparaître un Dionysos Ômèstès, cette contribution tente de donner une appréciation de la fiabilité de cet auteur comme source pour l’étude des épiclèses du polythéisme hellénique. La mise en perspective de ces deux passages au sein de l’œuvre plutarchéenne, mais aussi leur confrontation avec d’autres sources, permettent en effet de déterminer que, dans les deux cas, Plutarque a extrait cette épiclèse de son contexte cultuel originel pour la réintégrer dans un contexte historique tout autre. La mise au jour de ce procédé, soutenue par d’autres exemples, permet in fine d’esquisser des hypothèses et d’autres pistes de recherche sur l’utilisation des épiclèses divines par cet auteur.

Dans de plus en plus de domaines, la gestion de la chose publique s'opérationnalise dans un contexte de modernité radicale dont les caractéristiques (surinformation, indétermination, hyper-complexité, incertitude croissante et multiple, pluralisme, mobilité accrue des acteurs) imposent aux pouvoirs publics de repenser les conditions de l'exercice de l'autorité, tant du point de vue des dispositifs institutionnels que des référentiels et cadres mobilisés, pour en renforcer la réflexivité. Nous proposons de dresser une liste de facteurs facilitant une démarche réflexive, à partir de deux études de cas dans le domaine de l'environnement, l'une consacrée au rôle et au fonctionnement de la « SPAQuE », une agence publique fondée afin de gérer la politique de décontamination des sols en Belgique (Région wallonne) et l'autre aux transformations des modalités de décision publique pour certains projets d'aménagement (Permis par décret - PIR). Loin d'être des recettes, ces facteurs poussent l'acteur à se questionner sur la pertinence et les conditions pratiques et spécifiques à son organisation. [less ▲]

Asthma is a frequent chronic inflammatory disease which is often mistaken for simple bronchitis. The diagnosis is based on the association of symptoms and excessive airway calibre variability. When symptoms are present more than once a week, it is recommended to give low dose inhaled corticoids as a maintenance treatment together with, as needed, rapid acting beta2 agonist. In addition it is crucial to provide the patient with an education on the disease to reinforce adherence to the treatment. [less ▲]

We report the case of a 57-year-old patient in whom we found a pulmonary infection due to Mycobacterium malmoense. This patient had no immunodeficiency and responded quite rapidly to anti-tuberculous therapy. He was treated for 6 months by levofloxacine, myambutol, and nicotibine, followed by 3 months of clarithromycine, levofloxacine and myambutol. The patient improved clinically to become asymptomatic and the cavitary lesion shown at the CT-scan slightly decreased. The patient is still currently treated by clarithromycine and ciproxine.

Due to a variety of reasons, the previous century is characterized by an extraordinary growth in car use that has continued into the current century. This has resulted in serious environmental repercussions. Despite technological advancements, the externalities remain an ecological threat that can not be discarded by policy makers. Therefore, it is essential that policy makers focus on reducing car use and on stimulating the shift towards more environment-friendly transport modes. In this study, Q-methodology is adopted as the technique to segment people, and to ascertain which approaches and determinants matter to medium distance travel. Segmentation is important, as policy measures will be more efficient and effective if they are fine-tuned on specific target groups. The analysis revealed that four discourses preponderate the paradigm of environmentally sustainable transport: travelers who use public transport as a dominant alternative, car-dependent travelers, travelers with a positive perception of using public transport, and travelers with a preference for car use. Concerning rational, economic motives, individuals evaluate travel time reliability as most important. To increase the reliability policy makers should consider the use of separate bus lanes and traffic light manipulation. In addition, public transport can be made even more attractive, when costs of cars are made more variable by road or congestion charging. When the subjective motives are discussed, the differences between the different groups of travelers were more pronounced. Next to increasing the benefits of using public transport, policy makers should also pay attention to removing psycho-social barriers. [less ▲]

In this paper, daily traffic counts are explained and forecasted by different modeling philosophies, namely the ARIMAX and SARIMA(X) modeling approaches. Special emphasis is put on the investigation of the seasonality in the daily traffic data and on the identification and comparison of holiday effects at different site locations. To get prior insight in the cyclic patterns present in the daily traffic counts, spectral analysis provides the required framework to highlight periodicities in the data. Data originating from single inductive loop detectors, collected in 2003, 2004 and 2005, are used for the analyses. Four traffic count locations are investigated in this study, an upstream and downstream traffic count location on a highway that is excessively used by commuters and an upstream and downstream traffic count location on a highway that is typified by leisure traffic. The different modeling techniques pointed out that weekly cycles appear to determine the variation in daily traffic counts. The comparison between seasonal effects and holiday effects at different site locations revealed that both the ARIMAX and SARIMAX modeling approach are valid frameworks for the identification and quantification of possible influencing effects. The technique yielded the insight that holiday effects play a noticeable role on highways that are excessively used by commuters, while holiday effects have a more ambiguous effect on highways typified for their leisure traffic. Modeling of daily traffic counts on secondary roads, and simultaneous modeling of both the underlying reasons of travel and revealed traffic patterns, certainly are challenges for further research.

The phenomenon of backdraft is closely linked to the formation of a flammable region due to the mixing process between the unburned gases accumulated in the compartment and the fresh air entering the compartment through a recently created opening. The flow of incoming fresh air is called the gravity current. Gravity current prior to backdraft has already been studied, Fleischmann (1993, Backdraft phenomena, NIST-GCR-94-646. University of California, Berkeley) and Fleischmann (1999, Numerical and experimental gravity currents related to backdrafts, Fire Safety Journal); Weng et al. (2002, Exp Fluids 33:398–404), but all simulations and experiments found in the current literature are systematically based on a perfectly regular volume, usually parallelipedic in shape, without any piece of furniture or equipment in the compartment. Yet, various obstacles are normally found in real compartments and the question is whether they affect the gravity current velocity and the level of mixing between fresh and vitiated gases. In the work reported here, gravity current prior to backdraft in compartment with obstacles is investigated by means of three-dimensional CFD numerical simulations. These simulations use as a reference case the backdraft experiment test carried out by Gojkovic (2000, Initial Backdraft. Department of Fire Safety Engineering, Lunds Tekniska Ho¨ gskola Universitet, Report 3121). The Froude number, the transit time and the ignition time are obtained from the computations and compared to the tests in order to validate the model. [less ▲]

In this paper, daily traffic counts are explained and forecast by different modeling philosophies: an approach using autoregressive integrated moving average (ARIMA) models with explanatory variables (i.e., the ARIMAX model) and approaches using a seasonal autoregressive integrated moving average (SARIMA) model as well as a SARIMA model with explanatory variables (i.e., the SARIMAX model). Special emphasis is placed on the investigation of seasonality in daily traffic data and on the identification and comparison of holiday effects at different sites. To get insight into prior cyclic patterns in the daily traffic counts, spectral analysis provides the required framework to highlight periodicities in the data. The analyses use data from single inductive loop detectors, which were collected in 2003, 2004, and 2005. Four traffic count locations are investigated in this study: an upstream and a downstream traffic count site on a highway used extensively by commuters, and an upstream and a downstream traffic count site on a highway typically used for leisure travel. The different modeling techniques show that weekly cycles appear to determine the variation in daily traffic counts. The comparison between seasonal and holiday effects at different site locations reveals that both the ARIMAX and the SARIMAX modeling approaches are valid frameworks for identifying and quantifying possible influencing effects.

Dans les modèles télégraphiques,on considère que la communication fonctionne si les messages de départ et d’arrivée sont identiques.Sinon, cela signifie que le récepteur a mal compris ou que l’émetteur s’est mal fait comprendre. Dans ce cadre, la pathologie de la communication est l’incompréhension. Ce que nous proposons ici, à partir de l’analyse de situations de communication très particulières (des rencontres enchantées avec des dauphins sauvages), c’est que, à l’inverse, la structure fondamentale de la communication est le malentendu. Or, c’est le refus de reconnaître ce fait (dû notamment au désir vain et désastreux de contrôler le partenaire) qui engendre des pathologies.Admettre au contraire qu’émetteur et récepteur disposent nécessairement de versions différentes de l’interaction et qu’il n’y a pas de version plus objective qu’une autre, c’est replacer l’altérité au coeur d’une communication qui est réussie parce qu’on accepte de mal se comprendre.
