An upper bound on the Chebotarev invariant of a finite group
Full text linkA subset {g1,.., gd} of a finite group G invariably generates {g1x1,..,gdxd} generates G for every choice of xi ∈ G. The Chebotarev invariant C(G) of G is the expected value of the random variable n that is minimal subject to the requirement that n randomly chosen elements of G invariably generate G. The first author recently showed that C(G)≤β|G| for some absolute constant β. In this paper we show that, when G is soluble, then β is at most 5/3. We also show that this is best possible. Furthermore, we show that, in general, for each ε > 0 there exists a constant cε such that C(G)≤(1+∈)|G|+c
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author

Reconfiguring contract research? Career, work and learning in a changing employment landscape
No full textThis paper has been developed from research carried out within the ‘Learning as Work’ project, an ESRC funded multi-sector study in the UK (2003 – 2008)i. It discusses some initial findings from case study research which is focusing on the effects of contractual changes on the learning opportunities, working lives and career expectations experienced by contract research staff within Higher Education (HE) in the United Kingdom. The paper draws on a series of in-depth face-to-face interviews carried out with senior managers, contract research staff (CRS), principal investigators and other key staff members across three faculties, spanning both the ‘hard’ and ‘soft’ sciences, in one research intensive university. These are suggesting that it is unhelpful to consider CRS as an homogenous group. Factors relating to the historical relationship between research and career trajectories in contrasting disciplines; the requirements of diverse funding sources; changing expectations regarding ‘work-life balance’; the wider labour market context, as well as the nature of specific departments in terms of management style, priorities and culture, were all relevant to the lived experiences and perceptions of our sample
Through the Lens of Color: An Interview with Gareth Doherty, Author of Paradoxes of Green: Landscapes of a City-State
Full text linkThis interview by Mark Tirpak with Gareth Doherty of Harvard University Graduate School of Design, focuses on his Paradoxes of Green: Landscapes of a City-State (University of California Press, 2017). With Paradoxes of Green (2017) and via the interview, Doherty recounts some of the findings of his ethnographic fieldwork in the Kingdom of Bahrain and describes tensions arising from differing conceptions of what ‘green’ means or signifies within this growing and predominantly arid region. An argument that Doherty makes in Paradoxes of Green (2017) is that color and form are interlinked, and that color deserves deeper consideration by policy-makers and other formal shapers of cities. The interview draws from Paradoxes of Green (2017) to discuss some of Doherty’s findings as well as his latest work on the intersections between landscape architecture and anthropology

Finite groups with large Chebotarev invariant
Full text linkA subset {g1, ..., gd} of a finite group G is said to invariably generate G if the set {g1x1,...,gdxd} generates G for every choice of xi ∈ G. The Chebotarev invariant C(G) of G is the expected value of the random variable n that is minimal subject to the requirement that n randomly chosen elements of G invariably generate G. The authors recently showed that for each ε > 0, there exists a constant cε such that C(G)≤(1+ε)|G|+cε. This bound is asymptotically best possible. In this paper we prove a partial converse: namely, for each α > 0 there exists an absolute constant δ α such that if G is a finite group and C(G)>α|G|, then G has a section X/Y such that |X/Y|≥δα|G|, and X/ Y≅ Fq⋊ H for some prime power q, with H≤Fq×
