A manifesto for Web Science

A clarion call for a new research agenda has been sounded, notably by Berners-Lee et al (2006a 2006b) and Hendler et al (2008) for a ‘science of decentralised information systems’ to ‘discover’ generative mechanisms, and synthesise knowledge and technology to push both forwards. Computer Science alone - focussing as it does on the engineering/technology of the web - could not deliver the ambitions of this new agenda. Equally, other disciplines implicated in Web Science might use the web to support their research, or be interested in virtual life, but they lacked a coherent or unifying mandate for engaging with the web. By calling for Web Science these pioneers opened up a new space. But this is uncharted terrain. As a technology the web is still new. While it has grown rapidly and unexpectedly we are only just beginning to think about the web as a phenomena to be studied. The proponents of Web Science had the vision to see that this new approach had to include disciplines beyond their own; it had to be greater than the sum of the parts of individual disciplines. This is a radical call to leave disciplinary silos and work collaboratively to produce something bigger and better. Moreover, it takes in the founding principles of the web and a desire for a web that is pro-human: this is a call for a science that is capable of insight and intervention to create a better world. Our paper aims to take up this challenge and suggests how we might map the Web Science terrain. We come at this from a slightly different direction to the web science pioneers and want to demonstrate how social science can, and indeed must, contribute to developing Web Science. This paper will explore the contribution of social theory and sociological concepts that shape how we engage with the web. We focus on four key aspects which seem to be central to this understanding. Firstly co-constitution, the fact that the web both shapes and is shaped by humans/society. Secondly the importance of heterogeneous networks of multiple and diverse actors (including technologies themselves) that make the web as we know it. Thirdly the significance of performativity, that the web is an unfolding, enacted practice, as people interact with http to build ‘the web’ moment by moment. Finally, drawing these ideas together we see the web we have now as an immutable mobile or temporarily stabilised network. We use these ideas to map what web science could be and to suggest how we might use sociology to understand the web. Our aim is to provoke and stimulate debate and to move beyond superficial popular psychology and sociology (which envisages engineering human behaviour) and to challenge some of the ways in which social science has engaged with technology and technical actors. To facilitate this, and taking our lead from Donna Harroway, the paper sets out a radical manifesto for web science

Cultures within a culture: the role of nationality and religion for environmentally significant behaviour in students living in university accommodation

Reducing global warming cannot be achieved through technological interventions alone; it requires a change in human behaviour. Households are a major contributor to carbon emissions, and thus play an integral part in strategies aiming at a more sustainable living. Behaviour changes in the household can make a significant contribution towards reducing CO2 emissions. However, people vary strongly in their household practices; differences in behaviour account for a substantial amount of variance in heat, electricity, and water consumption (Gill et al., 2010). What causes these differences? In addition to age and education, nationality and religion play a role: They impact on physical aspects of well-being and on environmental attitudes (e.g., Isaacs et al., 2010; Guth et al., 1995). The physical aspect such as perception of warmth is of importance insofar as that comfort practices could influence on environmentally significant behaviour. The Eurobarometer 295 (2008), a study on the attitudes of European citizens towards the environment, also revealed differences in attitudes and behaviour of Europeans towards the environment. Therefore, steps to promote more sustainable living have to be adapted to different cultures. Rising globalization brings about more heterogeneous populations, meaning that there will be increasingly "cultures within a culture." An important question is what happens to cultural differences in environmentally significant behaviour in such a setting. It could be that differences are diluted by a largely shared environment, or that they continue to persist, thanks to being deeply rooted in one’s origin and to the non-shared part of the environment. Our study: The aim of this study was to examine the variation in pro-environmental attitudes, behaviour, and values in members of a community now living in a very similar setting but coming from diverse backgrounds. If personal background accounts for differences in the variables at stake, then this has important implications, e.g. for all national interventions launched to change behaviour. Data was collected through a web-based survey. The survey was sent out to first-year students living in university accommodation at the University of Greenwich. Religion, strength of religion, nationality, years living in the UK, program studied, gender and age were recorded and the impact of these variables on a variety of measures such as pro- environmental attitudes, values, and actual behaviour was assessed. Results are currently being analysed but preliminary data suggest that sub-culture does play a role and thus needs to be considered when developing carbon reduction interventions. The implications of these findings for the University and national policies are discussed

Complex epithelial remodeling underlie the fusion event in early fetal development of the human penile urethra.

We recently described a two-step process of urethral plate canalization and urethral fold fusion to form the human penile urethra. Canalization ("opening zipper") opens the solid urethral plate into a groove, and fusion ("closing zipper") closes the urethral groove to form the penile urethra. We hypothesize that failure of canalization and/or fusion during human urethral formation can lead to hypospadias. Herein, we use scanning electron microscopy (SEM) and analysis of transverse serial sections to better characterize development of the human fetal penile urethra as contrasted to the development of the human fetal clitoris. Eighteen 7-13 week human fetal external genitalia specimens were analyzed by SEM, and fifteen additional human fetal specimens were sectioned for histologic analysis. SEM images demonstrate canalization of the urethral/vestibular plate in the developing male and female external genitalia, respectively, followed by proximal to distal fusion of the urethral folds in males only. The fusion process during penile development occurs sequentially in multiple layers and through the interlacing of epidermal "cords". Complex epithelial organization is also noted at the site of active canalization. The demarcation between the epidermis of the shaft and the glans becomes distinct during development, and the epithelial tag at the distal tip of the penile and clitoral glans regresses as development progresses. In summary, SEM analysis of human fetal specimens supports the two-zipper hypothesis of formation of the penile urethra. The opening zipper progresses from proximal to distal along the shaft of the penis and clitoris into the glans in identical fashion in both sexes. The closing zipper mechanism is active only in males and is not a single process but rather a series of layered fusion events, uniquely different from the simple fusion of two epithelial surfaces as occurs in formation of the palate and neural tube

A sustainable model for ICT capacity building in developing countries

System administrators are often asked to apply their professional expertise in unusual situations, or under tight resource constraints. What happens, though, when the “situation” is a foreign country with only basic technical infrastructure, and the task is to bauild systems which are able to survive and grow in these over-constrained environments? In this paper we report on our experiences in two very different countries – Cuba and Ethiopia – where we ran a number of ICT projects. In those projects we assisted local universities to upgrade their ICT infrastructure and services. This included skills and process building for local system administrators. Based on our experiences we formulate a model for sustainable ICT capacity building. We hope this model will be useful for other organizations doing similar projects

Horses as Sources of Proprietary Information: Commercialization, Conservation, and Compensation Pursuant to the Convention on Biological Diversity

Horses indigenous to East and Southeast (E/SE) Asia, including native, landrace, feral, and wild populations, embody valuable genetic diversity. Conservation efforts for animals have largely been driven by humane altruism, with little consideration for the information value of genomes. Yet, if horses are viewed as archives of information as well as objects of affection, their conservation shifts to a market-based paradigm. Horse genetic resources (GR) likely contain significant value to the lucrative global horse industry, including veterinary applications such as diagnostics, therapeutics, genetic markers, gene therapies, and cloning technologies. As biotechnology becomes increasingly sophisticated, mining of horse GR will accelerate, thus facilitating identification, inventorying, bioprospecting, and commercialization of genetic information. Yet, establishing a value chain that balances equitable compensation for commercial applications while promoting conservation of horse populations remains a challenge. Recommendations presented here include establishing regional and national human resource and institutional capacity (competent national authorities), that catalog eco-geographical inventories of horse GR; monitor, manage, market and direct equitable value chains from horse to genetic information to commercial products; and ensure revenue flow back to support conservation. This system will foster market incentives to build capacity for sustainable conservation of the diverse horse populations of E/SE Asia

A HCI principles based framework to assess the user perception of web based Virtual Research Environments. Special issue on Capacity building for post disaster infrastructure development and management

Due to various challenges and opportunities such as globalisation of research agenda and advancements in information and communication technologies, research collaborations (both international and national) have become popular during the last decade more than ever before. Within this context, the concept of Virtual Research environments(VRE) is an emerging concept looking at addressing the complex challenges associated with conducting collaborative research. Even though concept of VRE is at its infancy, it is important to assess user perception about those, both to establish its success of uptake and future development strategies. However, to date, there is no formal method established to evaluate VREs .This paper reports a strategy adopted within an international collaborative research project (EURASIA) to evaluate its custom built VRE, VEBER, using the well known Computer Human Interaction principles

Collaborative Development and Evaluation of Text-processing Workflows in a UIMA-supported Web-based Workbench

Challenges in creating comprehensive text-processing worklows include a lack of the interoperability of individual components coming from different providers and/or a requirement imposed on the end users to know programming techniques to compose such workflows. In this paper we demonstrate Argo, a web-based system that addresses these issues in several ways. It supports the widely adopted Unstructured Information Management Architecture (UIMA), which handles the problem of interoperability; it provides a web browser-based interface for developing workflows by drawing diagrams composed of a selection of available processing components; and it provides novel user-interactive analytics such as the annotation editor which constitutes a bridge between automatic processing and manual correction. These features extend the target audience of Argo to users with a limited or no technical background. Here, we focus specifically on the construction of advanced workflows, involving multiple branching and merging points, to facilitate various comparative evalutions. Together with the use of user-collaboration capabilities supported in Argo, we demonstrate several use cases including visual inspections, comparisions of multiple processing segments or complete solutions against a reference standard, inter-annotator agreement, and shared task mass evaluations. Ultimetely, Argo emerges as a one-stop workbench for defining, processing, editing and evaluating text processing tasks
