The Small Histories project: the internet, life stories and 'performances of reconstruction'

This project revolves around Small Histories, an online web-based software system for the uploading and sharing of life stories: http://www.smallhistories.com. I created Small Histories to explore the ways in which the internet can facilitate the urge to tell, share and compare one’s personal history and, by doing so, generate an online network of interlinked personal narratives connected to historical times, events and places. The project originated with a personal event: the tracing of my biological Israeli father in 1997 and my subsequent explorations of my Israeli and German family histories. The stories I encountered in these explorations differed, depending on who was telling them. The Small Histories system was a response to the potential of the burgeoning internet to represent such differing viewpoints, and to generate new forms of encounters with the past. Since then the system has developed in tandem with the internet, especially the explosive growth over recent years of what has been called social software. Conceptually, this project explores the fast-evolving social internet as a setting for auto/biographical narrative practice and how this overlaps with and changes accepted notions of performance, community formation, identity construction and acts of memory. As a framework for these investigations, I propose that the internet is a catalyst without precedent for the production of performances of reconstruction, where fragments of the past are dug up, collected, assembled and presented as an imaginative reconstruction of ‘what used to be’, in an attempt to re-establish a lost sense of roots, identity and belonging; a coherent narrative of identity in an era of fragmentation

Analysis of Alternative Storage Conditions for DNA Recovery from Field Samples

As ecologists increasingly employ molecular methods, they find that tried and true preservation solutions (e.g. ethanol or formalin) may not be optimal when samples are targeted for genetic analyses. Before traveling to remote sample sites, researchers need to consider which preservation methods are likely to yield the largest quantity and highest quality of DNA based on their travel times and field conditions. They also need to consider whether they will have access to preservatives at remote sites and whether those preservatives can be safely transported. To determine which preservation methods would most reliably preserve tissue for genetic analysis under a range of field conditions, we examined total DNA recovery from female fruit flies (Drosophila melanogaster) individually held in various solutions (70% ethanol; 2% SDS, 100 mM EDTA; 1% SDS, 50 mM EDTA; 0.66% SDS, 33 mM EDTA; Zymo© lysis buffer; Zymo Xpedition© lysis buffer) at three different temperatures (22oC, 4oC and -20oC) for varying lengths of time (1 day, 4 weeks, and 8 weeks). We predicted that insects held in Zymo Xpedition© buffer would yield the overall highest DNA recovery since this buffer was designed for field collected animal tissue. We also predicted that variation in DNA recovery from insects held in different solutions would increase with preservation time and holding temperature. Although we observed significant differences in total DNA recovery from some of our samples, no trends were identified. Preliminary band quality analyses of PCR products utilizing stored DNA as template for amplification of the mCOI gene generally indicated decline in product quality as storage time increased. Future work will focus on better quantifying stored DNA quality and examining the relationship between total DNA recovered and overall DNA quality

Structures for Knowledge Co-creation Between Organisations and the Public

A definitive version of this conference paper is available in the ACM Digital Library http://dx.doi.org/10.1145/2556420.2558854© ACM 2014Social computing technologies are emerging to support innovative new relationships between organisations and the public. Inspired by concepts such as collective intelligence and crowdsourcing, diverse organisations are exploring new ways to increase engagement with the public, collect localised knowledge, or leverage human cognition and creativity. The COP2014 workshop will assimilate the craft understanding and experimentation underpinning innovations in relationships between public and professional realms. We aim to provide an opportunity for discussion and to build understanding of the principles of making these sociotechnical systems work, and discuss possible designs and opportunities that may be valuable and remain underexplored. As a tangible outcome, our main goal will be to co-author a paper discussing our positions on current systems and future visions, for submission to Communications of the ACM. We welcome participation from interested organisations, alongside those conducting research in this area. Topics of interest include: How can systems be designed for participation that is beneficial to individuals and organisations? How do we draw boundaries between ‘official’ and externally-generated knowledge? How can professional activities connect with the just-in-time, emergent nature of amateur interactions?RCUK Horizon Hu

Modelling the conference paper assignment problem

In this paper we describe different constraints and models for the conference paper assignment problem. While the core problem is a simple flow problem, additional constraints often arise to tailor a solution to specific wishes, or to increase perceived fairness for reviewers and/or submissions. We show some results from actual conferences paper assignments, and also investigate scalability of the method for large-scale events

Controlled interfacial assembly of 2D curved colloidal crystals and jammed shells

Assembly of colloidal particles on fluid interfaces is a promising technique for synthesizing two-dimensional micro-crystalline materials useful in fields as diverse as biomedicine1, materials science2, mineral flotation3 and food processing4. Current approaches rely on bulk emulsification methods, require further chemical and thermal treatments, and are restrictive with respect to the materials employed5-9. The development of methods that exploit the great potential of interfacial assembly for producing tailored materials have been hampered by the lack of understanding of the assembly process. Here we report a microfluidic method that allows direct visualization and understanding of the dynamics of colloidal crystal growth on curved interfaces. The crystals are periodically ejected to form stable jammed shells, which we refer to as colloidal armour. We propose that the energetic barriers to interfacial crystal growth and organization can be overcome by targeted delivery of colloidal particles through hydrodynamic flows. Our method allows an unprecedented degree of control over armour composition, size and stability.Comment: 18 pages, 5 figure

A new P-wave tomographic model (cap22) for North America: implications for the subduction and cratonic metasomatic modification history of western Canada and Alaska

Our understanding of the present-day state and evolution of the Canadian and Alaskan mantle is hindered by a lack of absolute P-wavespeed constraints that provide complementary sensitivity to composition in conjunction with existing S-wavespeed models. Consequently, cratonic modification, orogenic history of western North America and complexities within the Alaskan Proto-Pacific subduction system remain enigmatic. One challenge concerns the difficulties in extracting absolute arrival-time measurements from often-noisy data recorded by temporary seismograph networks required to fill gaps in continental and global databases. Using the Absolute Arrival-time Recovery Method (AARM), we extract >180,000 new absolute arrival-time residuals from seismograph stations across Canada and Alaska and combine these data with USArray and global arrival-time data from the contiguous US and Alaska. We develop a new absolute P-wavespeed tomographic model, CAP22, spanning North America that significantly improves resolution in Canada and Alaska over previous models. Slow wavespeeds below the Canadian Cordillera sharply abut fast wavespeeds of the continental interior at the Rocky Mountain Trench in southwest Canada. Slow wavespeeds below the Mackenzie Mountains continue farther inland in northwest Canada, indicating Proterozoic-Archean metasomatism of the Slave craton. Inherited tectonic lineaments colocated with this north-south wavespeed boundary suggest that both the crust and mantle may control Cordilleran orogenic processes. In Alaska, fast upper mantle wavespeeds below the Wrangell Volcanic Field favor a conventional subduction related mechanism for volcanism. Finally, seismic evidence for the subducted Kula and Yukon slabs indicate tectonic reconstructions of western North America may require revision

Political brand image: an investigation into the operationalisation of the external orientation of David Cameron’s Conservative brand

This paper seeks to address the limited understanding of how to operationalise the external brand image of a political brand. More specifically, this research critically assesses the transfer potential of the six variables of brand image by Bosch, Venter, Han and Boshoff to deconstruct the UK Conservative Party brand from the perspective of young people aged 18–24 years during the 2010 UK General Election campaign. This research demonstrates the applicability of the six variables otherwise known as the ‘brand image framework’ to the political environment. However, the application of the brand image framework in its original conceptualisation proved problematic. Many of the brand image variables were clarified, rearticulated and simplified to address the political context. This refined conceptualisation provided an in-depth understanding of how to investigate the political brand image of David Cameron’s Conservative Party. This study addresses the paucity of research that operationalises external brand image and provides practitioners and academics within and beyond the context of political branding a mechanism to understand the external orientation of brands. This research may also be used by political and non-political brands as a basis to explore external brand image and compare its consistency with internal brand identity

Political branding: sense of identity or identity crisis? An investigation of the transfer potential of the brand identity prism to the UK Conservative Party

Brands are strategic assets and key to achieving a competitive advantage. Brands can be seen as a heuristic device, encapsulating a series of values that enable the consumer to make quick and efficient choices. More recently, the notion of a political brand and the rhetoric of branding have been widely adopted by many political parties as they seek to differentiate themselves, and this has led to an emerging interest in the idea of the political brand. Therefore, this paper examines the UK Conservative Party brand under David Cameron’s leadership and examines the applicability of Kapferer’s brand identity prism to political branding. This paper extends and operationalises the brand identity prism into a ‘political brand identity network’ which identifies the inter-relatedness of the components of the corporate political brand and the candidate political brand. Crucial for practitioners, this model can demonstrate how the brand is presented and communicated to the electorate and serves as a useful mechanism to identify consistency within the corporate and candidate political brands
