    Acculturation, adaptation and multiculturalism among immigrant adolescents in junior vocational education

    Get PDF
    This thesis deals with the adaptation and acculturation of immigrant adolescents in junior vocational education. The adaptation of immigrant adolescents fits the notion of an 'immigrant paradox'. Maintaining aspects of the ethnic culture was found positively related to immigrant adolescents' adaptation.LEI Universiteit LeidenOpvoeding, diagnostiek en behandeling van kinderen en jeugdigen met (ernstige) ontwikkelings-, opvoedings-, en onderwijsprobleme

    A Web-platform for Linking IFC to External Information during the Entire Lifecycle of a Building

    AbstractDuring the lifecycle of a building, much more information is used and produced than can be contained inside a Building Information Model (BIM). The information outside the BIM is seldom connected to the BIM or connected across domains. Furthermore, information in BIM is only accessible to people with sufficient CAD or architectural background, and often expensive software is needed to edit and add data. This inefficient information management causes significant costs in practice. Our research contributes to the development of IFC based web applications in practice and demonstrates a way of linking machine to human readable data thus making the data accessible to non CAD users or architectural experts. In this paper we describe such a platform for the integration of model-based data and non-model based data. We tried to construct a mapping process from IFC properties to a national building element classification system, as a way of structuring the objects and information for use in our web platform. Since both the structure of IFC and most building element classification systems are based on semantic relations of building elements (i.e. holonym, meronym, hypernym), translations by means of a basic reasoning system should be feasible. We elaborate on several uses of this platform in applications for maintenance and reuse of building materials, buildings and built structures

    Modern and fossil non-pollen palynomorphs from the Basque mountains (western Pyrenees, France): the use of coprophilous fungi to reconstruct pastoral activity

    International audienceThis paper presents results from a modern dataset of non-pollen palynomorphs and its application to aca. 2,000 year peat record from the same area in the western Pyrenees (Basque Country, France). The modern dataset is composed of 35 surface samples (moss polsters) from a mountainous pasture-woodland landscape. Airborne fungal spores (ascospores and conidia), found dominant in the dataset, are linked to the degree of landscape openness and grazing pressure. The complete spectrum of 13 selected spore-types of dung-related Ascomycetes is positively linked with grazing pressure. However, different dung affinities between the spore-types have been identified. These are types clearly related to high grazing pressure and types with no or unclear dung indicative value. The modern dataset is used to aid interpretation of the local fossil pollen record as an independent 'proxy' to assess past pastoral dynamics. This study confirms the utility of modern nonpollen palynomorphs from terrestrial ecosystems in the reconstruction of historical local pastoral activities but also shows their limitation. It may be necessary to extend such study to wetland ecosystems and to investigate the spatial dimension of some fungal spores

    A Novel Connexin 26 Mutation in a Patient Diagnosed with Keratitis–Ichthyosis–Deafness Syndrome

    Keratitis–ichthyosis–deafness syndrome is a rare disorder characterized by erythrokeratoderma, deafness, and keratitis. Scarring alopecia and squamous cell carcinoma can also occur. Most cases described so far were sporadic. Here we present evidence that keratitis–ichthyosis–deafness syndrome is caused by a mutation in the connexin 26 gene. This finding expands the spectrum of disorders caused by defects in connexin 26 and implies the gene in normal corneal function, hair growth, and carcinogenesis
