    The impact of idle time in the classroom: differential effects on children with ADHD

    No full text
    Objective: Studies have identified an exacerbation of ADHD deficits under specific laboratory conditions. Less is known about the significance of such contextual factors in relation to everyday functioning in naturalistic settings. Method: This study investigated the differential impact of classroom “idle time”—periods when students are not actively engaged or waiting for a task—on the behavior of 31 children with ADHD (25 boys and 6 girls; aged 6-12 years) and 31 sex- and age-matched typically developing classmates, who were simultaneously observed in their normal classroom during two school days. Results: Both groups experienced the same amount of idle time (12% of the time). During idle time, however, levels of hyperactivity and noisiness increased significantly more in children with ADHD than in their classmates (p < .05). Conclusion: Findings highlight the differential susceptibility of ADHD children to classroom idle time. Classroom interventions might consider targeting specifically these periods to reduce disruptive behavior in these children

    Formal Techniques and Self/Other Relations in the Novels of Dirk Bogarde

    No full text
    The thesis foregrounds the distinctive contribution Dirk Bogarde made to contemporary writing in a second career that developed in parallel to his screen commitments. It dispels the notion that Bogarde followed a familiar path as an actor who wrote books. Instead it establishes his reputation as an innovative writer whose formal technique was substantially influenced by the textual systems of cinema and the cross-fertilisation from acting to writing. In examining the formative factors that steered Bogarde towards authorship, the thesis addresses the role of performance as a generative factor in the evolution of the novels, establishing a discursive link with Bakhtinian dialogism, and specifically, transgredience as a formal imperative. Secondly, it affords a critical insight into why the major concerns with staging and performativity preoccupy his writing career. The thesis claims that Bogarde was an empirically dialogical writer whose use of camera-eye narration fostered the proliferation of competing discourses across the fiction. This formal dynamic is centred on the relationship between stages and dialogism, which incorporates the work of Erving Goffinan as a complementary critique to Bakhtinian theory with its emphasis on self-presentation. The concern with socially-constructed behaviour leads the thesis to address the associated issues of stereotyping and 'otherness', which in terms of body politics is articulated by the mono logic drive to confine the sexual 'other' to a fixed representation. Bogarde's ability to draw on cinematic and performance techniques identifies an area of expertise unavailable to most other writers. This is an unusual repository of skills to bring to writing which is why the thesis makes the claim for his singular achievement as a contemporary author. There are fruitful points of intersection to be explored in this respect with the work of Christopher Isherwood, whom Bogarde read and admired, as a basis for further research. It is hoped that the thesis will play its part in opening up new possibilities for Bogarde's writing to be re-visited by future critics

    Altered circadian profiles in attention-deficit/hyperactivity disorder: an integrative review and theoretical framework for future studies

    No full text
    Abstract: Disruptions in the sleep-wake cycle and the circadian system have been found in a wide range of psychiatric disorders and are generally correlated with clinical severity and diminished quality of life. Emerging evidence suggests similar disturbances may be found in attention-deficit/hyperactivity disorder (ADHD). Here we review the available literature on across the day fluctuations in ADHD-related processes in terms of; (i) time of day effects on behavior and activity; (ii) morningness-eveningness chronotypology; (iii) sleep/wake rhythms; and (iv) rhythmicity in neuroendocrine and neurophysiological responsiveness. On this basis, we propose a neurobiological framework to guide future study, which sees circadian effects in ADHD, along with other aspects of ADHD arousal-related deficits (e.g., cognitive energetic deficits), as being the result of dysregulated locus coeruleus function. Based on this perspective specific recommendations for future research are presented. (C) 2012 Elsevier Ltd. All rights reserved

    The impact of instructional context on classroom on-task behavior: A matched comparison of children with ADHD and non-ADHD classmates

    No full text
    Classroom inattentiveness is an important reason for clinical referral of children with ADHD and a strong predictor of their educational achievement. This study investigates classroom on-task behavior of Flemish children with ADHD withdrawn from medication as a function of instructional context. Thirty-one pairs of children (one with ADHD and one age- and sex-matched control; 25 boys and 6 girls 6 to 12 years of age) were observed in their classroom environment during two consecutive school days. On-task behavior (time on-task and on-task span) of ADHD and non-ADHD individuals was compared in different class contexts (i.e., different class structures and academic content types). Individualized teacher supervision was simultaneously assessed. Generalized estimation equation analyses showed that children with ADHD were significantly less on-task than controls during individual work and whole class group teaching, but not during small group work, and had significantly shorter on-task span during academic tasks (mathematics, language, and sciences) and instructional transitions between tasks, but not during music and arts. These effects persisted even after controlling for the higher levels of teacher supervision observed for ADHD pupils (7%) across all contexts (vs. 4% in controls). Findings suggest that despite receiving more overall teacher supervision, children with ADHD displayed lower levels of on-task behavior in settings that place high self-regulatory, information processing, and motivational demands on them. This finding may have initial implications for classroom interventions in this population

    "The end of national models? Integration courses and citizenship trajectories in Europe"

    No full text
    Several European countries have recently introduced or are planning to introduce citizenship trajectories (voluntary or obligatory inclusion programs for recent immigrants) or citizen integration tests (tests one should pass to be able and acquire permanent residence or state citizenship). Authors like Joppke claim this is an articulation of a more general shift towards the logic of assimilation (and away from a multicultural agenda) in integration policy paradigms of European States. Integration policies would even be converging in such a fashion that it would no longer make sense to think in terms of national models for immigrant integration. One cannot deny the empirical fact of diffusion of civic integration policies throughout Europe. This paper claims there is, however, still sufficient distinctiveness between immigrant integration policies in order to continue and use an analytical framework which distinguishes national models

    Printable Cement-Based Materials: Fresh Properties Measurements and Control

    No full text
    Digital fabrication with cementitious materials is a rapidly growing field of research in which the evolution of strength during the various processes, such as 3D printing, is the key controlling parameter. The strength evolves over multiple orders of magnitude during the process, and thus, it is essential to properly characterize the strength evolution in order to guarantee process success. This chapter summarizes the state of the art in these characterization methods for digital fabrication with fresh cementitious materials, reviewing well-known and more recently developed methods.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Concrete Structure
