    When Will Arctic Sea Ice Be Gone?

    No full text
    The Arctic sea ice is the ice that is floating on the Arctic Ocean. In recent decades, this pack ice has been disappearing very rapidly. So the question arises when the Arctic sea ice will be completely gone. DIRK NOTZ has examined this using the Arctic summer sea ice in September as example. As he explains in this video, his research group combined satellite observations with model simulations and found a clear linear correlation between the loss of Arctic sea ice and carbon dioxide emissions. For each ton of CO2 we emit, we make about three square meters of Arctic sea ice disappear. From this linear relationship the researchers could extrapolate the amount of carbon dioxide that can still be emitted before the Arctic sea ice is completely gone in summers. For the first time, these findings present very intuitive numbers that make clear the impact every individual has on the global warming

    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

    "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

    A short history of climate change

    No full text
    The flux of energy through the climate system determines the living conditions of our planet. In this contribution, I outline the main processes regulating this flux of energy, how these processes have changed throughout Earth history, and how today they are changing by human activities, in particular by activities related to energy production. The changes in the climate state of our planet, which have been ongoing ever since the formation of the Earth some 5 billion years ago, have shaped the world we live in today. Yet, today’s climate change is special in two overarching ways. First, it is the first time that a major climate change is globally affecting a civilisation that is perfectly adapted to thousands of years of stable climate conditions. Second, today’s climate change is occurring at a rate much faster than preceding natural climate changes. In combination, these two factors make today’s climate change a unique challenge to humankind, with direct consequences of future energy production as outlined in the other contributions to this volume

    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
