This article outlines the utility of the term ‘post-punk polymath’ to describe the sustained multi-medium and intertextual artistic practice engaged in by artists of the post-punk scene on New York’s ...Lower East Side in the late 1970s. Through the example of Kembra Pfahler and a detailed analysis of Lydia Lunch, it discusses the unique environment of artistic collaboration in the city that was sustained by the subcultures that occupied the dilapidated neighbourhood of the Lower East Side. In this countercultural interzone, which flourished because of, rather than despite New York’s municipal degradation, Lunch remembers that ‘everyone was doing everything’. As both Lunch and Pfahler are artists whose practices encompass music, visual art, installation, literature and film, it is only by understanding their work across a multitude of artistic mediums that a sense of their wider artistic strategy can be arrived at. As I argue throughout, they are not musicians who also happen to produce film or installation, but post-punk polymaths engaged in a unified practice sustained and encouraged by the subcultural environment that they matured within.
In this article, we analyse the domain mapping method approach to approximate statistical moments of solutions to linear elliptic partial differential equations posed over random geometries including ...smooth surfaces and bulk-surface systems. In particular, we present the necessary geometric analysis required by the domain mapping method to reformulate elliptic equations on random surfaces onto a fixed deterministic surface using a prescribed stochastic parametrisation of the random domain. An abstract analysis of a finite element discretisation coupled with a Monte-Carlo sampling is presented for the resulting elliptic equations with random coefficients posed over the fixed curved reference domain and optimal error estimates are derived. The results from the abstract framework are applied to a model elliptic problem on a random surface and a coupled elliptic bulk-surface system and the theoretical convergence rates are confirmed by numerical experiments.
In this thesis, we will begin by analysing the domain mapping method for elliptic partial differential equations defined over random surfaces and random bulk-surface systems. In particular, we will ...begin by deriving expressions for the pull-back of geometric quantities and tangential differential operators defined over a random surface, onto a deterministic reference surface via a prescribed domain mapping. These calculations will allow for the original considered elliptic equations posed either over a random surface or a random bulk-surface system, to be reformulated respectively onto a deterministic reference surface and a deterministic bulk-surface system, and lead to the consideration of stochastic elliptic equations posed over a deterministic domain. An abstract analysis will subsequently be presented to treat the arising equations, and a numerical scheme based upon a piecewise linear finite element discretisation and a linear approximation of the curved reference domain will be presented and analysed in the abstract setting. Optimal error estimates will be derived and the convergence rates will be numerical verified in the case of a model elliptic surface equation and a coupled bulk-surface system. In the following chapter, we extend the application of the domain mapping method to the consideration of advection-diffusion equations posed over randomly evolving surfaces and randomly evolving bulk-surface systems. This will similarly entail first deriving expressions for the pullback of time-dependent quantities, such as the material derivative, onto the reference domain, which will allow for a reformulation of the considered partial differential equations posed over the random domain, onto the reference domain to take place. After which, an abstract analysis of the stochastic partial differential equations which arise after reformulating the original advection-diffusion equations onto the deterministic reference domain will be presented. A numerical scheme based upon a piecewise linear finite element approximation coupled with a single level Monte-Carlo sampling, will subsequently be presented and analysed in the abstract setting and optimal error estimates will be derived. The convergence rate are subsequently numerically verified. The thesis will then conclude with a future outlook on the applications of the domain mapping method, in particular examining how the domain mapping method may applied to a Hele-Shaw problem and a two-phase Stefan problem both posed over a random surface.

Ms. Vaginal “Crème” Davis has come to occupy a unique position in the parallel and intertwining histories of performance and live art, punk, and queer subcultures. As lead singer of the Afro Sisters, ...black fag, Pedro, Muriel & Esther (PME), and ¡Cholita! The Female Menudo, she developed a fearsome reputation and cult following on the alternative music scene of the late 1970s, 1980s, and 1990s, emerging as a prime antagonist of the post-punk subgenre Queercore. Alongside this musical practice, she directs and stars in her own independent films and theatrical productions, and was a central figure in the burgeoning fanzine culture of the 1980s, producing both home-printed magazines and the influential video-zine
. Davis also ran and hosted several highly influential performance/club nights in Los Angeles throughout the 1990s and 2000s including Club Sucker, G.I.M.P., and Bricktops. Now living in Berlin, Davis continues to produce work as a performer, visual artist, sculptor, and writer, and as a musician with her most recent bands Tenderloin and Ruth Fisher. Davis produces work that blends a peculiarly Angeleno understanding of celebrity, glamor, and showbiz with the cultural politics of race, sexuality, privilege, and class, all made within a DIY ethos that stretches back to the earliest days of Californian punk. This interview was recorded in a cold Berlin on December 3, 2014, at Davis's home in Schöneberg.
Ms. Vaginal "Creme" Davis has come to occupy a unique position in the parallel and intertwining histories of performance and live art, punk and queer subcultures. As lead singer of the Afro Sisters, ...black fag, Pedro, Muriel & Esther (PME) and !Cholita!The Female Meundo, she developed a fearsome reputation and ccult following on the alternative music scene for the last three decades, emerging as a prime antagonist of the post-punk subgenre Queercore. She directs and stars in her own independent films and theatrical productions, has produced many fanzines. Her interview with Lewis Church, on artistic practice, the city of Los Angeles and QPOC (queer people of color) creativity and activism, is represented here.
When do information retrieval systems using two document clusters provide better retrieval performance than systems using no clustering? We answer this question for one set of assumptions and suggest ...how this may be studied with other assumptions. The “Cluster Hypothesis” asks an empirical question about the relationships between documents and user‐supplied relevance judgments, while the “Cluster Performance Question” proposed here focuses on the when and why of information retrieval or digital library performance for clustered and unclustered text databases. This may be generalized to study the relative performance of m versus n clusters.
This dissertation answers three research questions: (1) What are the characteristics of a combinatoric measure, based on the Average Search Length (ASL), that performs the same as a probabilistic ...version of the ASL?; (2) Does the combinatoric ASL measure produce the same performance result as the one that is obtained by ranking a collection of documents and calculating the ASL by empirical means?; and (3) When does the ASL and either the Expected Search Length, MZ-based E, or Mean Reciprocal Rank measure both imply that one document ranking is better than another document ranking? Concepts and techniques from enumerative combinatorics and other branches of mathematics were used in this research to develop combinatoric models and equations for several information retrieval ranking methods and performance measures. Empirical, statistical, and simulation means were used to validate these models and equations. The document cut-off performance measure equation variants that were developed in this dissertation can be used for performance prediction and to help study any vector "V" of ranked documents, at arbitrary document cut-off points, provided that (1) relevance is binary and (2) the following information can be determined from the ranked output: the document equivalence classes and their relative sequence, the number of documents in each equivalence class, and the number of relevant documents that each class contains. The performance measure equations yielded correct values for both strongly- and weakly-ordered document collections.
