Enterprising women: independence, finance and Virago Press, c.1976-1993

Virago Press were established in 1972 and became one of the twentieth century’s most enduring publishing brands. As a women-led enterprise, articulations of independence have defined key moments in Virago’s history. This article explores two moments when the company re-structured as independent, in 1976 and 1987. To become successful, Virago had to overcome barriers that have historically hindered women’s participation in business, namely limited social capital and difficulties accessing finance. Virago founder Carmen Callil’s friendships with publisher Paul Hamlyn and printing entrepreneur Robert Gavron embedded Virago in networks of male entrepreneurial knowledge that helped shape the evolution of the company. Such networks were vital to Virago securing investment from Rothschilds Ventures Limited in 1987 who were, at that time, leading figures in the UK’s growing private equity industry. This article contributes to growing historical understanding of the synergies between financial, arts and culture industries in the 80s. It argues that while this era offered new opportunities for women to participate in business, such participation was tempered by new forms of legal and financial discipline that re-calibrated existing gender inequalities within business cultures. Due to the time periods under consideration, this article also analyses how entrepreneurial practices and opportunities for women changed dramatically with the onset of Thatcher’s ‘Enterprise Culture’

Tuning the electronic transport properties of graphene through functionalisation with fluorine

Engineering the electronic properties of graphene has triggered great interest for potential applications in electronics and opto-electronics. Here we demonstrate the possibility to tune the electronic transport properties of graphene monolayers and multilayers by functionalisation with fluorine. We show that by adjusting the fluorine content different electronic transport regimes can be accessed. For monolayer samples, with increasing the fluorine content, we observe a transition from electronic transport through Mott variable range hopping in two dimensions to Efros - Shklovskii variable range hopping. Multilayer fluorinated graphene with high concentration of fluorine show two-dimensional Mott variable range hopping transport, whereas CF0.28 multilayer flakes have a band gap of 0.25eV and exhibit thermally activated transport. Our experimental findings demonstrate that the ability to control the degree of functionalisation of graphene is instrumental to engineer different electronic properties in graphene materials.Comment: 6 pages, 5 figure

Phonons in potassium doped graphene: the effects of electron-phonon interactions, dimensionality and ad-atom ordering

Graphene phonons are measured as a function of electron doping via the addition of potassium adatoms. In the low doping regime, the in-plane carbon G-peak hardens and narrows with increasing doping, analogous to the trend seen in graphene doped via the field-effect. At high dopings, beyond those accessible by the field-effect, the G-peak strongly softens and broadens. This is interpreted as a dynamic, non-adiabatic renormalization of the phonon self-energy. At dopings between the light and heavily doped regimes, we find a robust inhomogeneous phase where the potassium coverage is segregated into regions of high and low density. The phonon energies, linewidths and tunability are remarkably similar for 1-4 layer graphene, but significantly different to doped bulk graphite.Comment: Accepted in Phys. Rev.

A review of residual stress analysis using thermoelastic techniques

Thermoelastic Stress Analysis (TSA) is a full-field technique for experimental stress analysis that is based on infra-red thermography. The technique has proved to be extremely effective for studying elastic stress fields and is now well established. It is based on the measurement of the temperature change that occurs as a result of a stress change. As residual stress is essentially a mean stress it is accepted that the linear form of the TSA relationship cannot be used to evaluate residual stresses. However, there are situations where this linear relationship is not valid or departures in material properties due to manufacturing procedures have enabled evaluations of residual stresses. The purpose of this paper is to review the current status of using a TSA based approach for the evaluation of residual stresses and to provide some examples of where promising results have been obtained

Teaching Issues of Identity Through Multicultural Young Adult Literature

Despite changing demographics of high school classrooms, teaching practices and literature remain similar to decades-old practices focusing more on literary devices and symbolism than on topics relevant to the students. Many teachers don’t have the time to find new novels. And when they do find the texts, they are often at a loss for how to properly teach the novels. This thesis is a three-part paper advocating for teaching identity to high school students using a blend of classic literature and contemporary multicultural young adult literature. The first section focuses on personal experiences and research illustrating the need for more multicultural literature in English curriculum. Teenagers need to explore their own identities, but novels that focus on situations not relevant to their situation or culture leads to feelings of marginalization and a disinterest in literature in general. Certain obstacles keep a more progressive teaching approach from happening, but teachers can overcome the obstacles by focusing on student needs. The second section of the thesis outlines an example unit teaching identity using an older novel, The Great Gatsby, with the newer multicultural young adult novel, American Street. It makes connections between a search for one’s identity as it relates to race and the American dream. The unit gives ideas for questions and activities to enrich discussion of the novels. Section three of the thesis lists other exemplary contemporary young adult multicultural texts teachers will find useful as they seek additional opportunities to diversify their curriculum. Each novel includes a summary as well as a brief analysis of how the novel connects to identity and culture

Green spines, back story: delving into the early history of Virago reprints and modern classics

While the iconic green spines of Virago Modern Classics have become a fixture in the literary imagination, D-M Withers looks into the early history of feminist publisher Virago Press to explore how the decision to publish a fiction reprint list represented a significant change in the publishing strategy of a company whose main activity had been non-fiction, in new or reprint form

Generation of internal stress and its effects

Internal stresses may be generated continually in many polycrystalline materials. Their existence is manifested by changes in crystal defect concentration and arrangement, by surface observations, by macroscopic shape changes and particularly by alteration of mechanical properties when external stresses are simultaneously imposed

Compositional uniformity, domain patterning and the mechanism underlying nano-chessboard arrays

We propose that systems exhibiting compositional patterning at the nanoscale, so far assumed to be due to some kind of ordered phase segregation, can be understood instead in terms of coherent, single phase ordering of minority motifs, caused by some constrained drive for uniformity. The essential features of this type of arrangements can be reproduced using a superspace construction typical of uniformity-driven orderings, which only requires the knowledge of the modulation vectors observed in the diffraction patterns. The idea is discussed in terms of a simple two dimensional lattice-gas model that simulates a binary system in which the dilution of the minority component is favored. This simple model already exhibits a hierarchy of arrangements similar to the experimentally observed nano-chessboard and nano-diamond patterns, which are described as occupational modulated structures with two independent modulation wave vectors and simple step-like occupation modulation functions.Comment: Preprint. 11 pages, 11 figure
