Newton-Okounkov bodies on projective bundles over curves

In this article, we study Newton-Okounkov bodies on projective vector bundles over curves. Inspired by Wolfe's estimates used to compute the volume function on these varieties, we compute all Newton-Okounkov bodies with respect to linear flags. Moreover, we characterize semi-stable vector bundles over curves via Newton-Okounkov bodies.Comment: 28 pages. Final version: to appear in Mathematische Zeitschrif

On singular Fano varieties with a divisor of Picard number one

In this paper we study the geometry of mildly singular Fano varieties on which there is an effective prime divisor of Picard number one. Afterwards, we address the case of toric varieties. Finally, we treat the lifting of extremal contractions to universal covering spaces in codimension 1.Comment: 35 pages.

Kinkon biobib: life and work of Dom Sylvester Houedard

Bio-bibliographical essay on British Benedictine monk, scholar, translator, concrete poet and artist Dom Sylvester Houédard (1924–92). Based on scarce published materials and primary sources, this chronology emphasises artistic over religious and other activities, and public over private ones. It lists events where Houédard had an active involvement (group and solo exhibitions – focusing on UK based ones, and those where a catalogue was published; talks, readings and performances – including recordings; collaborations), significant artworks, monographic publications (broadsheets, print folders, cards, pamphlets, monographs, exhibition catalogues, anthologies) and serial publications (articles and magazines)

Biennalization? What biennalization?: the documentation of biennials and other recurrent exhibitions

Biennials have been central to the development of contemporary art for decades, but there is a paucity of published material specifically related to this subject. Documentation for these important exhibitions is not always made available and it is often difficult to acquire, posing an obstacle to current and future research across a number of areas within contemporary art, curating and art history. This article offers an overview of major current biennials and of the different sources of information they produce (catalogues, other printed material, online resources, archives), and surveys the secondary literature of the phenomenon. It also discusses specific collection development issues in libraries, from a research perspective, proposing a set of recommendations for best practice

Democracy and Inquiry in the Post-Truth Era: A pragmatist Solution

Post-truth has become a commonplace strategy. No longer are objective facts viewed as having evidentiary value; scientific knowledge is on a par with emotions or personal beliefs. We intend to show that in the context of post-truth, those proffering and receiving an assertion do not care about the truth-value of the assertion or about the best way to gather evidence concerning it. Such attitudes raise several questions about how relativism can be a corrupting influence in contemporary democracies. We will analyse Steve Fuller’s use of the term «post-truth» – especially, the political connotations about epistemic democracy that he highlights. Instead, we offer a pragmatist defence of the truth and an alternative meaning of epistemic democracy

From Cambridge to Brighton: Concrete poetry in Britain, an interview with Stephen Bann

Extensive interview with art historian, curator and concrete poet Stephen Bann by Gustavo Grandal Montero, focusing particularly on his curatorial, critical and artistic work of the 1960s, closely involved with the development of Concrete poetry in the UK. Associated at an early stage with Ian Hamilton Finlay, he co-organized the First International Exhibition of Concrete and Kinetic Poetry (Cambridge, 1964) and was Director of the Concrete Poetry Exhibition for the inaugural Brighton Festival in 1967, edited Concrete poetry: an international anthology 1967 and published several influential critical texts, while developing his own Concrete poetry practice

The principle of autonomy and biotechnological applications : a bioethics approach

What is it that makes the subject of bioethics autonomous? The problem that this research tries to clarify is What is it that makes the subject of bioethics autonomous? This question is answered from an applied ethics, bioethics. This article will show a new methodological approach to study the subject of bioethics. The principal objetives of this research that is presented here, are related to the relationship between: 1) Autonomy and information; 2) Autonomy and responsability; 3) Autonomy and freedom; and 4) Autonomy and social ties or social links
