2D3D2D: a diagnostic approach to textile and fashion research practice
In the School of Art and Design, at Nottingham Trent University, a range of research methods and practices have developed through PhD and post doctoral study in relation to printed textile design and new technology. Individual research projects have addressed pattern (Bunce 1993); photographic imagery (Briggs 1997); colour (Leak 2001); non-repeating pattern (Carlisle 2003) and 2D/3D (Townsend 2003). Post-doctoral research (Briggs-Goode & Bunce 2001) and Townsend's research into 2D/3D informed a group project and exhibition Transforming Shape (2004). The outcomes created by Gillian Bunce, Amanda Briggs-Goode, Gillian Bunce, Rosemary Goulding and Katherine Townsend explored the relationships between innovative surface imagery and three-dimensional prototypes, based on the simple geometric forms of square, rectangle and circle
A requirement for STAG2 in replication fork progression creates a targetable synthetic lethality in cohesin-mutant cancers.
Cohesin is a multiprotein ring that is responsible for cohesion of sister chromatids and formation of DNA loops to regulate gene expression. Genomic analyses have identified that the cohesin subunit STAG2 is frequently inactivated by mutations in cancer. However, the reason STAG2 mutations are selected during tumorigenesis and strategies for therapeutically targeting mutant cancer cells are largely unknown. Here we show that STAG2 is essential for DNA replication fork progression, whereby STAG2 inactivation in non-transformed cells leads to replication fork stalling and collapse with disruption of interaction between the cohesin ring and the replication machinery as well as failure to establish SMC3 acetylation. As a consequence, STAG2 mutation confers synthetic lethality with DNA double-strand break repair genes and increased sensitivity to select cytotoxic chemotherapeutic agents and PARP or ATR inhibitors. These studies identify a critical role for STAG2 in replication fork procession and elucidate a potential therapeutic strategy for cohesin-mutant cancers
Conflict and seduction in the public sphere
In a critical but sympathetic reading of Habermas’s work (1984, 1987a, 1987b, 2003), Luke Goode (2005) recently sought to rework his theory of deliberative democracy in an age of mediated and increasingly digital public spheres. Taking a different approach, Alan McKee (2005) challenged the culture- and class-bound strictures of Habermasian rationalism, instead pursuing a more radically pluralist account of postmodern public spheres. The editors of this special section of Media, Culture & Society invited us to discuss our differing approaches to the public sphere. Goode holds that the institutional bases of contemporary public spheres (political parties, educational institutions or public media) remain of critical importance, albeit in the context of a kaleidoscopic array of unofficial and informal micro-publics, both localized and de-territorialized. In contrast, McKee sustains a ‘hermeneutics of suspicion’ toward the official, hegemonic institutions of the public sphere since they tend to exclude and delegitimize discourses and practices that challenge their polite middle-class norms.\ud

McKee’s recent research has focused on sexual cultures, particularly among youth (McKee, 2011). Goode’s recent work has examined new social media spaces, particularly in relation to news and public debate (e.g. Goode, 2009; Goode et al., 2011). Consequently, our discussion turned to a domain which links our interests: after Goode discussed some of his recent research on (in)civility on YouTube as a new media public sphere, McKee challenged him to consider the case of pornographic websites modelled on social media sites.1 He identifies a greater degree of ‘civility’ in these pornographic sibling sites than on YouTube, requiring careful consideration of what constitutes a ‘public sphere’ in contemporary digital culture. Such sites represent an environment that shatters the opposition of public and private interest, affording public engagement on matters of the body, of intimacy, of gender politics, of pleasure and desire – said by many critics to be ruled out of court in Habermasian theory. Such environments also trouble traditional binaries between the cognitive and the affective, and between the performative and the deliberative.\ud

In what follows we explore the differences between our approaches in the form of a dialogue. As is often the case, our approaches seemed less at odds after engaging in conversation than may have initially appeared. But important differences of emphasis remain
What makes a 'good group'? Exploring the characteristics and performance of undergraduate student groups
Group work forms the foundation for much of student learning within higher education, and has many educational, social and professional benefits. This study aimed to explore the determinants of success or failure for undergraduate student teams and to define a ‘good group’ through considering three aspects of group success: the task, the individuals, and the team. We employed a mixed methodology, combining demographic data with qualitative observations and task and peer evaluation scores. We determined associations between group dynamic and behaviour, demographic composition, member personalities and attitudes towards one another, and task success. We also employed a cluster analysis to create a model outlining the attributes of a good small group learning team in veterinary education. This model highlights that student groups differ in measures of their effectiveness as teams, independent of their task performance. On the basis of this, we suggest that groups who achieve high marks in tasks cannot be assumed to have acquired team working skills, and therefore if these are important as a learning outcome, they must be assessed directly alongside the task output

Aeolia: textile enquiry and design
In this essay we introduce ongoing research in the field of technical textiles at Nottingham Trent University involving specialists from a range of disciplines. We will reflect on the roles and experiences of people as they worked within and across their usual boundaries of practice. In particular, the key aspects of risk, unfamiliarity, and criteria for success will be discussed. The project emerged from a strategic investment by the University in a number of interdisciplinary fellowships, in this case across Product Design and Textiles. A commercially available but under researched fibre had been identified as a starting point with the potential for contribution to the field. This carbonised rubber cord, 2mm in diameter, changes its electrical properties when stretched, meaning it may be used in conjunction with a circuit to drive outputs such as light, sound or movement
General properties of cosmological models with an Isotropic Singularity
Much of the published work regarding the Isotropic Singularity is performed
under the assumption that the matter source for the cosmological model is a
barotropic perfect fluid, or even a perfect fluid with a -law equation
of state. There are, however, some general properties of cosmological models
which admit an Isotropic Singularity, irrespective of the matter source. In
particular, we show that the Isotropic Singularity is a point-like singularity
and that vacuum space-times cannot admit an Isotropic Singularity. The
relationships between the Isotropic Singularity, and the energy conditions, and
the Hubble parameter is explored. A review of work by the authors, regarding
the Isotropic Singularity, is presented.Comment: 18 pages, 1 figur
