The pragmatic constructions of Deleuze, Guattari and Miles Davis
No full textThe aim of the following investigation is two-fold. Firstly, the project takes as its focus the growing corpus of secondary literature written on the work of the French philosophers and theorists Gilles Deleuze and Felix Guattari, whose work has generated a great deal of
interest in recent years and a proportionate amount of controversy. Much of this controversy can be attributed to simplifications and misunderstandings on the part of
commentators who have in some instances neglected to approach Deleuze and Guattari with sufficent rigour and care, resulting in the perpetuation of so many misunderstandings regarding their work.
Secondly, the project will seek to redress some of these misunderstandings by recourse to a pragmatic embodiment of Deleuze and Guattari's concepts and ideas through a case-study based on the life and work of the African-American jazz musician Miles Davis. In attempting to provide a new and challenging case as the basis for this investigation, the overriding aim is to assess the pragmatic remit of Deleuze and Guattari's thought, in terms of aesthetics, ethics and politics, whilst remaining sensitive to the potential limitations and dangers of their project

Breast and prostate cancer: more similar than different
No full textBreast cancer and prostate cancer are the two most common invasive cancers in women and men, respectively. Although these cancers arise in organs that are different in terms of anatomy and physiological function both organs require gonadal steroids for their development, and tumours that arise from them are typically hormone-dependent and have remarkable underlying biological similarities. Many of the recent advances in understanding the pathophysiology of breast and prostate cancers have paved the way for new treatment strategies. In this Opinion article we discuss some key issues common to breast and prostate cancer and how new insights into these cancers could improve patient outcomes.Gail P. Risbridger, Ian D.

Dual VP Classes
No full textWe consider the complexity class ACC^1 and related families of arithmetic circuits. We prove a variety of collapse results, showing several settings in which no loss of computational power results if fan-in of gates is severely restricted, as well as presenting a natural class of arithmetic circuits in which no expressive power is lost by severely restricting the algebraic degree of the circuits. These results tend to support a conjecture regarding the computational power of the complexity class VP over finite algebras, and they also highlight the significance of a class of arithmetic circuits that is in some sense dual to VP.Presented at the 40th International Symposium on Mathematical Foundations of Computer Science (MFCS '15).Published as a chapter in: Mathematical foundations of computer science 2015 : 40th International Symposium, MFCS 2015, Milan, Italy, August 24-28, 2015, Proceedings.

Effect of changes in testing parameters on the cost-effectiveness of two pooled test methods to classify infection status of animals in a herd
No full textMonte Carlo simulation was used to determine optimal fecal pool sizes for identification of all Mycobacterium avium subsp. paratuberculosis (MAP)-infected cows in a dairy herd. Two pooling protocols were compared: a halving protocol involving a single retest of negative pools followed by halving of positive pools and a simple protocol involving single retest of negative pools but no halving of positive pools. For both protocols, all component samples in positive pools were then tested individually. In the simulations, the distributions of number of tests required to classify all individuals in an infected herd were generated for various combinations of prevalence (0.01, 0.05 and 0.1), herd size (300, 1000 and 3000), pool size (5, 10, 20 and 50) and test sensitivity (0.5–0.9). Test specificity was fixed at 1.0 because fecal culture for MAP yields no or rare false-positive results. Optimal performance was determined primarily on the basis of a comparison of the distributions of numbers of tests needed to detect MAP-infected cows using the Mann–Whitney U test statistic. Optimal pool size was independent of both herd size and test characteristics, regardless of protocol. When sensitivity was the same for each pool size, pool sizes of 20 and 10 performed best for both protocols for prevalences of 0.01 and 0.1, respectively, while for prevalences of 0.05, pool sizes of 10 and 20 were optimal for the simple and halving protocols, respectively. When sensitivity decreased with increasing pool size, the results changed for prevalences of 0.05 and 0.1 with pool sizes of 50 being optimal especially at a prevalence of 0.1. Overall, the halving protocol was more cost effective than the simple protocol especially at higher prevalences. For detection of MAP using fecal culture, we recommend use of the halving protocol and pool sizes of 10 or 20 when the prevalence is suspected to range from 0.01 to 0.1 and there is no expected loss of sensitivity with increasing pool size. If loss in sensitivity is expected and the prevalence is thought to be between 0.05 and 0.1, the halving protocol and a pool size of 50 is recommended. Our findings are broadly applicable to other infectious diseases under comparable testing conditions.ID: S0167587710000085; M3: Article; Accession Number: S0167587710000085; Author: Locksley L. McV.

Diversifying information literacy research: An informed learning perspective
No full textThis article uses the idea of informed learning, an interpretation of information literacy that focuses on people's information experiences rather than their skills or attributes, to analyse the character of using information to learn in diverse communities and settings, including digital, faith, indigenous and ethnic communities. While researchers of information behaviour or information seeking and use have investigated people's information worlds in diverse contexts, this work is still at its earliest stages in the information literacy domain. To date, information literacy research has largely occurred in what might be considered mainstream educational and workplace contexts, with some emerging work in community settings. These have been mostly in academic libraries, schools and government workplaces. What does information literacy look like beyond these environments? How might we understand the experience of effective information use in a range of community settings, from the perspective of empirical research and other sources? The article concludes by commenting on the significance of diversifying the range of information experience contexts, for information literacy research and professional practice. © 2013 by Emerald Group Publishing Limited
[Guest editorial] Qualitative Research Journal special issue: Approaches to researching masculinities
No full textIn 1993 the journal <i>Theory and Society</i> published, within their twenty-second volume, a special issue, Number 5: Masculinities. This publication constituted 8 papers gleaned from two international conferences held in 1991, one California and in Sydney, Australia. Both meetings discussed Masculinities as an emerging ‘set of issues … (namely:) sexuality and its social meaning, systems of domination …, construction and deconstruction of cultural representations of the masculine, men's material interests and the divisions among men’[1]. Both conferences were situated as a response to the popularity of an essentialist men’s movement that had peaked in momentum due to the publication of Robert Bly’s Iron John [2] a year earlier. This collection of papers sought to problematise masculinity as a field of academic interest and has become influential in later years as heralding a way forward.\ud

Twenty years later the <i>Qualitative Research Journal</i> is including within its fifteenth volume, a special edition, issue number 3: Approaches to Masculinities. The journal is currently seeking papers, which delineate approaches to research in this area by exploring new methods, theories, or conceptual constructions. R. W. Connell suggested, in the editorial of the 1993 issue, what was being presented was in fact a ‘meeting, where a number of projects illuminate (d) each other’[1]. In keeping with this spirit of collegiality the QRJ editorial team will co-ordinate a review process that will initially only include invited contributors. It is the hope that through a process of focused interdisciplinary peer review we will indeed illuminate our activity, progress the work within this field, be able to respond generously to our peers, and forge increased understanding between disciplines.\ud

Transforming Power Relationships: Leadership, Risk, and Hope. IHS Political Science Series No. 135, May 2013
No full textChronic communal conflicts resemble the prisoner’s dilemma. Both communities prefer peace to war. But neither trusts the other, viewing the other’s gain as its own loss, so
potentially shared interests often go unrealized.
Achieving positive-sum outcomes from apparently zero-sum struggles requires a kind of riskembracing leadership. To succeed leaders must: a) see power relations as potentially
positive-sum; b) strengthen negotiating adversaries instead of weakening them; and c) demonstrate hope for a positive future and take great personal risks to achieve it.
Such leadership is exemplified by Nelson Mandela and F.W. de Klerk in the South African democratic transition. To illuminate the strategic dilemmas Mandela and de Klerk faced, we examine the work of Robert Axelrod, Thomas Schelling, and Josep Colomer, who highlight important dimensions of the problem but underplay the role of risk-embracing leadership. Finally we discuss leadership successes and failures in the Northern Ireland settlement and the Israeli-Palestinian conflict
