Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
3SUM and Related Problems in Fine-Grained Complexity (Invited Talk)
No full text3SUM is a simple to state problem: given a set S of n numbers, determine whether S contains three a,b,c so that a+b+c = 0. The fastest algorithms for the problem run in n² poly(log log n)/(log n)² time both when the input numbers are integers [Ilya Baran et al., 2005] (in the word RAM model with O(log n) bit words) and when they are real numbers [Timothy M. Chan, 2020] (in the real RAM model).
A hypothesis that is now central in Fine-Grained Complexity (FGC) states that 3SUM requires n^{2-o(1)} time (on the real RAM for real inputs and on the word RAM with O(log n) bit numbers for integer inputs). This hypothesis was first used in Computational Geometry by Gajentaan and Overmars [A. Gajentaan and M. Overmars, 1995] who built a web of reductions showing that many geometric problems are hard, assuming that 3SUM is hard. The web of reductions within computational geometry has grown considerably since then (see some citations in [V. Vassilevska Williams, 2018]).
A seminal paper by Pǎtraşcu [Mihai Pǎtraşcu, 2010] showed that the integer version of the 3SUM hypothesis can be used to prove polynomial conditional lower bounds for several problems in data structures and graph algorithms as well, extending the implications of the hypothesis to outside computational geometry. Pǎtraşcu proved an important tight equivalence between (integer) 3SUM and a problem called 3SUM-Convolution (see also [Timothy M. Chan and Qizheng He, 2020]) that is easier to use in reductions: given an integer array a of length n, do there exist i,j ∈ [n] so that a[i]+a[j] = a[i+j]. From 3SUM-Convolution, many 3SUM-based hardness results have been proven: e.g. to listing graphs in triangles, dynamically maintaining shortest paths or bipartite matching, subset intersection and many more.
It is interesting to consider more runtime-equivalent formulations of 3SUM, with the goal of uncovering more relationships to different problems. The talk will outline some such equivalences. For instance, 3SUM (over the reals or the integers) is equivalent to All-Numbers-3SUM: given a set S of n numbers, determine for every a ∈ S whether there are b,c ∈ S with a+b+c = 0 (e.g. [V. Vassilevska Williams and R. Williams, 2018]).
The equivalences between 3SUM, 3SUM-Convolution and All-Numbers 3SUM are (n²,n²)-fine-grained equivalences that imply that if there is an O(n^{2-ε}) time algorithm for one of the problems for ε > 0, then there is also an O(n^{2-ε'}) time algorithm for the other problems for some ε' > 0. More generally, for functions a(n),b(n), there is an (a,b)-fine-grained reduction [V. Vassilevska Williams, 2018; V. Vassilevska Williams and R. Williams, 2010; V. Vassilevska Williams and R. Williams, 2018] from problem A to problem B if for every ε > 0 there is a δ > 0 and an O(a(n)^{1-δ}) time algorithm for A that does oracle calls to instances of B of sizes n₁,…,n_k (for some k) so that ∑_{j = 1}^k b(n_j)^{1-ε} ≤ a(n)^{1-δ}. With such a reduction, an O(b(n)^{1-ε}) time algorithm for B can be converted into an O(a(n)^{1-δ}) time algorithm for A by replacing the oracle calls by calls to the B algorithm. A and B are (a,b)-fine-grained equivalent if A (a,b)-reduces to B and B (b,a)-reduces to A.
One of the main open problems in FGC is to determine the relationship between 3SUM and the other central FGC problems, in particular All-Pairs Shortest Paths (APSP). A classical graph problem, APSP in n node graphs has been known to be solvable in O(n³) time since the 1950s. Its fastest known algorithm runs in n³/exp(√{log n}) time [Ryan Williams, 2014]. The APSP Hypothesis states that n^{3-o(1)} time is needed to solve APSP in graphs with integer edge weights in the word-RAM model with O(log n) bit words. It is unknown whether APSP and 3SUM are fine-grained reducible to each other, in either direction. The two problems are very similar. Problems such as (min,+)-convolution (believed to require n^{2-o(1)} time) have tight fine-grained reductions to both APSP and 3SUM, and both 3SUM and APSP have tight fine-grained reductions to problems such as Exact Triangle [V. Vassilevska Williams and R. Williams, 2018; V. Vassilevska and R. Williams, 2009; V. Vassilevska Williams and Ryan Williams, 2013] and (since very recently) Listing triangles in sparse graphs [Mihai Pǎtraşcu, 2010; Tsvi Kopelowitz et al., 2016; V. Vassilevska Williams and Yinzhan Xu, 2020]. The talk will discuss these relationships and some of their implications, e.g. to dynamic algorithms

The Donald Hunsberger Wind Band Transcription of Ralph Vaughan Williams' Variations for Brass Band: Historical Profile, Performance Practice, Conducting Considerations, and Corrected Edition
No full textThesis (D.M.A.)--University of Washington, 2012Abstract The Donald Hunsberger Wind Band Transcription of Ralph Vaughan Williams' Variations for Brass Band: Historical Profile, Performance Practice, Conducting Considerations, and Corrected Edition Gary Thomas Brattin Chairperson of the Supervisory Committee: Professor Timothy O. Salzman School of Music As one of the final works from a career lasting six decades, Ralph Vaughan Williams' Variations for Brass Band (1957) is a tremendous composition remaining in some obscurity relative to his works in other genres. Although it is widely accepted as standard repertoire in brass band circles, this composition has largely been passed over by scholars of Vaughan Williams' art music. The focus of this dissertation is Donald Hunsberger's transcription for wind band of Vaughan Williams' Variations for Brass Band; Hunsberger's transcription was made in 1988 and published ten years later. This transcription is an especially clear case illustrating the need to oversee all facets of a publication. The published score and parts of the transcription reveal an unusually high number of errata and printing discrepancies, totaling over 900 separate items. The ultimate goal of this research is to produce a new critical edition of the score and parts of Hunsberger's Variations for Wind Band. Several chapters are dedicated to this, with an overview of the types of errata, listings of the actual errata, and additional necessary editorial refinements. The corrected parts and score are included in a format for academic use only, produced using Finale® 2012 music notation software. This dissertation also provides historical and performance context for this work. It includes interviews with Donald Hunsberger (Eastman Wind Ensemble) and Paul Hindmarsch (British brass band authority), analysis of Vaughan Williams' other music for brass and wind bands, and examination of ten recordings in three versions of Variations (for brass band, orchestra, and wind band) to show the influence of tempi inserted into the music by editor Frank Wright. The consideration of tempo indications is particularly important because Vaughan Williams' original manuscript does not contain any metronomic tempi. Timed measurements of each variation in the recordings are compared with computerized default timings of the versions for brass and wind band, with the conclusion that a reconsideration, and even an outright removal, of some tempo indications might be appropriate in a new and corrected edition
Reconstructing identities: a study of Toni Morrison´s beloved and Dionne Brand´s at the full and change of the moom
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoAnálise das obras Beloved e At the Full and Change of the Moon, investigando de que maneira a reconstrução do passado, presente nestes dois romances, influencia a reconstrução da identidade negra. Para esta análise, utilizei alguns conceitos sobre identidade discutidos por Frantz Fanon, Stuart Hall e Cornel West. Estes entendem a identidade negra como um conceito que foi construído através da imposição de estereótipos coloniais. Além disso, vêem a identidade negra mais como um processo do que algo já fixado. Como nos romances analisados o passado colonial é "re-contado", tento mostrar aqui a relação da escravatura com as estratégias de identificação que as duas autoras retratam em suas obras. Já que cada autora narra experiências diferentes e fala de um local enunciativo específico, elas também retratam diferentes estratégias de formação de identidade. Em Beloved, a identidade é construída através da resistência à dominação branca, o que leva a uma estratégia emancipatória de sobrevivência. Já em At the Full and Change of the Moon, a identidade negra é desintegrada, pois os negros estão espalhados por todo o mundo, o que leva a uma estratégia assimilacionista. Este trabalho conclui que as duas autoras tentam mostrar a importância do entendimento da experiência de escravidão para a reconstrução das identidades negra

Evaluating Research Impact through Open Access to Scholarly Communication
No full textScientific research is a competitive business – in order to secure funding, promotion and tenure researchers must demonstrate their work has impact in their field. To maximise impact researchers undertake high priority research, aim to get results first, and publish in the highest impact journals. The Internet now presents a new opportunity to the scholarly author seeking higher impact: s/he can now make their work instantly accessible on the Web through author self-archiving. This growing body of open access literature (coupled with new publishing models that make journals available for-free to the reader) maximises research impact by maximising the number of people who can read it, and making it available sooner. Open access also provides a new opportunity for bibliometric research. This thesis describes the relatively recent phenomenon of open access to research literature, tools that were built to collect and analyse that literature, and the results of analyses of the effect of open access and its effect on author behaviour. It shows that articles self-archived by authors receive between 50-250% more citations, that rapid pre-printing on the Web has dramatically reduced the peak citation rate from over a year to virtually instant and how citation-impact – now widely used for evaluation – can be expanded to include a new web metric of download impact

The poetics of indefinition
No full textArtykuł jest owocem refleksji nad najnowszą poezją polską, szczególnie tzw. nowych dykcji. Bliska lektura początku poematu Bohdana Zadury 1 VIII 1979 7.45 - 22.45 [czternaście godzin z Piotrem Sommerem] oraz Wiersza o przecinkach Piotra Sommera prowadzi - z jednej strony - do sformułowania tezy o niewystarczalności dotychczasowych koncepcji poetyk momentalnych (autor podejmuje dyskusję z koncepcją "zgramatykalizowania systemu wersowego wytwarzania komunikatów" zaproponowaną przez Artura Grabowskiego), z drugiej zaś - do wypracowania koncepcji wiersza zaangażowanego po stronie zmian (w ramach szerszej charakterystyki modernistycznych poetyk nieokreśloności).This article is the product of reflection on contemporary Polish poetry, particularly the new diction. A close reading of the beginning of Bohdan Zadura’s poem "1 VIII 1979 7.45 - 22.45 [czternaście godzin z Piotrem Sommerem]" (1 August 1979, 7:45-22:45 [fourteen hours with Piotr Sommer]) and Piotr Sommer’s “Wiersz o przecinkach” (Poem About Commas) leads to, on the one hand, positing a thesis on the inadequacy of previous conceptions of poetics of the moment (the author enters into a discussion with the concept of "grammaticalizing the system of line-by-line production of messages" proposed by Artur Grabowski), and, on the other hand, to the development of a concept of the poem engaged on the side of change (within a broader description of modernist poetics of indefinition)
