    Automorphisms and opposition in twin buildings

    Full text link
    We show that every automorphism of a thick twin building interchanging the halves of the building maps some residue to an opposite one. Furthermore we show that no automorphism of a locally finite 2-spherical twin building of rank at least 3 maps every residue of one fixed type to an opposite. The main ingredient of the proof is a lemma that states that every duality of a thick finite projective plane admits an absolute point, i.e., a point mapped onto an incident line. Our results also hold for all finite irreducible spherical buildings of rank at least 3, and as a consequence we deduce that every involution of a thick irreducible finite spherical building of rank at least 3 has a fixed residue

    Das Briefgeheimnis: Ingeborg Bachmann and Paul Celan's Poetics of Correspondence

    Ingeborg Bachmann and Paul Celan are two of the foremost German-language poets of the post-1945 era. Celan, a Jewish poet whose parents were murdered in the Holocaust, and Bachmann, the Austrian daughter of a National Socialist, both sought a way to write after atrocity. Both writers struggled to use German as a poetic medium in their poetry and prose, as language appeared to have been poisoned through its association with National Socialism. Wider cultural concerns such as Theodor Adorno's dictum that to write poetry after Auschwitz is barbaric influenced the post-catastrophic literary landscape. In 1958, Celan famously compared writing poetry after 1945 to sending out a message in a bottle. This metaphor characterizes his dialogic approach to writing poetry. Famously, Bachmann and Celan carried out a poetic dialogue in their published work as they shared motifs and themes which they reinterpreted in their own works. From the time that Bachmann and Celan first met in Vienna in 1948, they began exchanging letters and poetry until Celan's death in 1970. In 2008, the letters that Bachmann and Celan exchanged between 1948 and 1967 were published for the first time in the volume Herzzeit. These letters provide new insights into the authors' struggle to find a viable mode of expression after 1945, and how they sought to overcome these problems through constructing a dialogue. This thesis will argue that Bachmann and Celan continued their poetic dialogue in some of the letters and that these letters serve as a poetic form in their own right

    The end of austerity? Not for the most needy

    The Chancellor’s 2016 Autumn Statement spoke of the ‘end of austerity’. It also announced the government’s aim to do more for those who are ‘just about managing’. Amidst all this, one might easily miss the crucial fact that austerity has just dramatically intensified for one particularly vulnerable group of people, write Alice Forbess and Deborah James

    Acts of assistance: navigating the interstices of the British state with the help of non-profit legal advisers

    This paper explores everyday interactions with the British welfare state at a moment when it is attempting to shift and transform its funding regimes. Based on a study situated in the offices of two London legal services providers, it draws attention to the role of a set of actors poised between local state officers and citizens: the advisers who carry out the work of translation, helping people to actualize their rights and, at the same time, forcing disparate state agencies to “speak to one another.” Advice and governmental services providers are increasingly part of the same system, helping to correct each other’s faults. At the same time, legal advisers’ work runs counter to the state’s aims when formal legal process is used to challenge unfair legislation. The picture is neither one of a separation between state and civil society, nor is it one in which a monolithic state is ineluctably eroding the independence of the third sector. Instead, ever more complex, blurred and idiosyncratic tangles of state, business and third sector are emerging in the field of public services

    Altered intrinsic functional coupling between core neurocognitive networks in Parkinson\u27s disease

    Parkinson3s disease (PD) is largely attributed to disruptions in the nigrostriatal dopamine system. These neurodegenerative changes may also have a more global effect on intrinsic brain organization at the cortical level. Functional brain connectivity between neurocognitive systems related to cognitive processing is critical for effective neural communication, and is disrupted across neurological disorders. Three core neurocognitive networks have been established as playing a critical role in the pathophysiology of many neurological disorders: the default-mode network (DMN), the salience network (SN), and the central executive network (CEN). In healthy adults, DMN–CEN interactions are anti-correlated while SN–CEN interactions are strongly positively correlated even at rest, when individuals are not engaging in any task. These intrinsic between-network interactions at rest are necessary for efficient suppression of the DMN and activation of the CEN during a range of cognitive tasks. To identify whether these network interactions are disrupted in individuals with PD, we used resting state functional magnetic resonance imaging (rsfMRI) to compare between-network connectivity between 24 PD participants and 20 age-matched controls (MC). In comparison to the MC, individuals with PD showed significantly less SN–CEN coupling and greater DMN–CEN coupling during rest. Disease severity, an index of striatal dysfunction, was related to reduced functional coupling between the striatum and SN. These results demonstrate that individuals with PD have a dysfunctional pattern of interaction between core neurocognitive networks compared to what is found in healthy individuals, and that interaction between the SN and the striatum is even more profoundly disrupted in those with greater disease severity
