People now know me for something positive: an evaluation of Big hART’s work at the John Northcott Estate
No full textThe following report provides a review of Big hART’s work in the Northcott Estate since 2002. From this time, Big hART in association with project partners carried out a series of community cultural development projects that culminated in the production of photographic portrait work, music, geo-spatial maps, performance theatre, filmmaking, narrative and writing pieces, and a series of other performance and arts-based activities. The intention of Big hART was to help ‘empower’ and assist tenants of Northcott to tell their stories, help build people’s sense of community, and encourage conditions that decrease violence and isolation. The Northcott Narratives Project is the title used to encompass all the separate but related projects undertaken by Big hART at the Northcott Estate from the period 2002- 2007.
This report does two things. Section one describes the purposes of the evaluation and considers the aims and aspirations of Big hART and its two major funding partners against the evidence. This section involves an ‘audit review’ of the work1. The second section draws on recent scholarship within the field to make a series of observations about how this was achieved and the approaches used by Big hART and its partners. This section involves an ‘open inquiry’ into the personal, social and organisational changes and benefits brought about by Big hART’s. It is the combination of both of these approaches that not only describes the social impacts of the arts in relation to the Northcott Narratives Project, but how they can be better understood and built on (Belfiore & Bennett, 2007)
Big hART at John Northcott Estate: Community, Health and the Arts
No full textThis paper considers the work of Big hART, a social impact of the Arts company, in their residency entitled Northcott Narratives over three and half years at John Northcott Estate, a public housing estate in Sydney. During this time Big hART used arts practice to engage tenants, strengthen their creative dispositions, and build relationships between tenants and a range of different communities. Northcott Narratives used a variety of multi-modal forms with tenants to inquire into, and then express ideas in relation to issues that confront them. These ideas are presented as social policy recommendations. The power and benefits of this form of arts practice along with the tensions and challenges are revealed. The paper adds to the developing discourse in relation to community cultural development
On the Northcott property for infinite extensions
No full textWe start with a brief survey on the Northcott property for subfields of the algebraic numbers \Qbar. Then we introduce a new criterion for its validity (refining the author's previous criterion), addressing a problem of Bombieri. We show that Bombieri and Zannier's theorem, stating that the maximal abelian extension of a number field contained in has the Northcott property, follows very easily from this refined criterion. Here denotes the composite field of all extensions of of degree at most

On the Northcott property and other properties related to polynomial mappings
No full textWe prove that if K/ℚ is a Galois extension of finite exponent and K(d) is the compositum of all extensions of K of degree at most d, then K(d) has the Bogomolov property and the maximal abelian subextension of K(d)/ℚ has the Northcott property. Moreover, we prove that given any sequence of finite solvable groups {Gm}m there exists a sequence of Galois extensions {Km}m with Gal(Km /ℚ)=Gm such that the compositum of the fields Km has the Northcott property. In particular we provide examples of fields with the Northcott property with uniformly bounded local degrees but not contained in ℚ(d). We also discuss some problems related to properties introduced by Liardet and Narkiewicz to study polynomial mappings. Using results on the Northcott property and a result by Dvornicich and Zannier we easily deduce answers to some open problems proposed by Narkiewic
Universal quadratic forms and Northcott property of infinite number fields
No full textWe show that if a universal quadratic form exists over an infinite degree, totally real extension of the field of rationals , then the set of totally positive integers in the extension does not have the Northcott property. In particular, this implies that no universal form exists over the compositum of all totally real Galois fields of a fixed prime degree over . Further, by considering the existence of infinitely many square classes of totally positive units, we show that no classical universal form exists over the compositum of all such fields of degree (for each fixed odd integer ).author accepted manuscript, 19 page
Northcott property and universality of higher degree forms
No full textLet be a totally real number field, a positive integer, and a higher degree form over . We prove that there are at most finitely many totally real extensions of degree such that over is universal. Further, we show that there are no universal forms over totally real infinite extensions of having the Northcott property.15 pages, comments are welcome
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Degree of explanation
No full textPartial explanations are everywhere. That is, explanations citing causes that explain some but not all of an effect are ubiquitous across science, and these in turn rely on the notion of degree of explanation. I argue that current accounts are seriously deficient. In particular, they do not incorporate adequately the way in which a cause’s explanatory importance varies with choice of explanandum. Using influential recent contrastive theories, I develop quantitative definitions that remedy this lacuna, and relate it to existing measures of degree of causation. Among other things, this reveals the precise role here of chance, as well as bearing on the relation between causal explanation and causation itself
