    This thesis is a discourse analysis of spoken argumentation in the Adult ESOL classroom. It investigates the ways in which it emerges and unfolds and also how teachers and students position themselves and each other in argumentation and how they are positioned by pedagogy and policy as well as by their histories. The principal focus is on verbal argumentation but some attention is also given to a more multimodal analysis. Argumentation is conceptualized in terms of competing and consensual voices (Costello and Mitchell, 1995). These voices are further conceptualized as situated speaking positions and, therefore, as identity positions. The study explores the ways in which argumentation unfolds, the ways it seeks to persuade and the identity work this involves. Argumentation is connected to wider questions of citizenship and democracy, with the Adult ESOL classroom seen as the agora for the wider enactment and modelling of full democratic citizenship

    Death and organization: Heidegger’s thought on death and life in organizations

    Get PDF
    Mortality has not been given the attention it deserves within organization studies. Even when it has been considered, it is not usually in terms of its implications for own lives and ethical choices. In particular, Heidegger’s writing on death has been almost entirely ignored both in writing on death and writing on organizational ethics, despite his insights into how our mortality and the ethics of existence are linked. In this paper, we seek to address this omission by arguing that a consideration of death may yield important insights about the ethics of organizational life. Most important of these is that a Heideggerian approach to death brings us up against fundamental ethical questions such as what our lives are for, how they should be lived and how we relate to others. Heideggerarian thought also reconnects ethics and politics, as it is closely concerned with how we can collectively make institutions that support our life projects rather than thwart or diminish them

    Synthesis and cycloadditions of 9H-furo[3,4-b][1]benzo(thio)pyran-9-ones: furan ring formation by a novel hydrolytically induced cycloreversion

    C-2 lithiation of acetals 2 followed by trapping with aldehydes gives 3. Subsequent unmasking of the acetal function provides furobenzo(thio)pyrans 4, cycloadditions of which have been investigated

    The directed lithiation of some 3-acylchromone acetals

    3-Acylchromone acetals are lithiated at C-2. Subsequent electrophilic trapping gives chromones 4 together with a ring-contracted dimer 6. During the formation of some acetals, an acid-catalysed rearrangement to a 2-substituted 3-formylchromone acetal is observed

    Virus-Like Particle Facilitated Deposition of Hydroxyapatite Bone Mineral on Nanocellulose after Exposure to Phosphate and Calcium Precursors

    We produced and isolated tobacco mosaic virus-like particles (TMV VLPs) from bacteria, which are devoid of infectious genomes, and found that they have a net negative charge and can bind calcium ions. Moreover, we showed that the TMV VLPs could associate strongly with nanocellulose slurry after a simple mixing step. We sequentially exposed nanocellulose alone or slurries mixed with the TMV VLPs to calcium and phosphate salts and utilized physicochemical approaches to demonstrate that bone mineral (hydroxyapatite) was deposited only in nanocellulose mixed with the TMV VLPs. The TMV VLPs confer mineralization properties to the nanocellulose for the generation of new composite materials
