Experimentation

Working across earth and social sciences, this article reevaluates resilience’s conceptual framework, drawing out alternative pathways for understanding and responding to the dislocations of the Anthropocene. Via a critical reading of the Anthropocene with the help of resilience’s adaptive cycle heuristic, I locate the possibility of new forms of life in its phase of release and reorganisation: the back loop. More than a brief, negative phase to govern or navigate, I argue that the back loop o ers the possibility for a practical orientation to the Anthropocene based on experimentation with new uses, release of old frameworks, and allowance for the unknown. Inhabiting the back loop, as I call it, articulates an ethos couched not in fear or survival but rather creative and technical audacity in unsafe operating space, as embodied already in a variegated landscape of practitioners.

This study reports on the evaluation of four meeting techniques for decision-making by small groups. Two face-to-face and two computer conferencing techniques were evaluated by small groups solving business cases. Particular groups varied widely in their satisfaction with different meeting techniques, but there was no significant difference in the quality of the group decisions.

Efficient processing of top- k queries is a crucial requirement in many interactive environments that involve massive amounts of data. In particular, efficient top- k processing in domains such as the Web, multimedia search, and distributed systems has shown a great impact on performance. In this survey, we describe and classify top- k processing techniques in relational databases. We discuss different design dimensions in the current techniques including query models, data access methods, implementation levels, data and query certainty, and supported scoring functions. We show the implications of each dimension on the design of the underlying techniques. We also discuss top- k queries in XML domain, and show their connections to relational approaches.

Bespace is a synchronous web3D lecture hall and performance system that seeks to tap the educational and entertainment potential of virtual space. Its underlying interactive methodology is focused on the efficient delivery of information within the space. The entire virtual environment is treated as a one interface. Principles of human computer interaction are applied to the activities, avatars, and architecture. The outcome is an environment that utilizes the power of a digitally created reality and does not sacrifice usability in pursuit of realistic appearances. Bespace’s interactive methodology seeks to implement the promises made by the early pioneers of virtual space. ACM Classification: H5.2 [Information interfaces and

In this paper, a combined use of dimensional analysis (DA) and modern statistical design of experiment (DOE) methodologies is proposed for a hydrodynamics experiment where there are a large number of variables. While DA is well-known, DOE is still unfamiliar to most ocean engineers although it has been shown to be useful in many engineering and non-engineering applications. To introduce

Within the scope of ANSWER, an EC-supported research project, a new artistic notation system, called DirectorNotation, is being developed for describing media content, much like notes are used to document a music composition. Our current research focuses on developing “notation-enabled ” offline authoring tools, but interactive applications are an anticipated extension. Here, we summarise the key aspects of DirectorNotation and the ANSWER project, from the point of view of a multimedia-technology audience interested in content-based manipulation of media.

En estos últimos años, el concepto de smart city se ha impuesto en los discursos y prácticas urbanas, transformándose en un sello cada vez más anhelado por las me-trópolis de todo el mundo. El denominado smart urbanism surge de la premisa que indica que, por medio de la aplicación de soluciones digitales, las urbes pueden transformarse en territorios más eficientes, predecibles y sustentables. Pero, ¿qué escenarios y consecuencias sociotécnicas plantea la extensión de sensores y algo-ritmos inteligentes en la ciudad? En este artículo exploro algunos de los debates contemporáneos y desafíos analíticos que emergen frente a la noción de ciudad in-teligente. Me sirvo de claves interpretativas provenientes de los Science and Technology Studies (STS) y discuto la naturaleza experimental de la noción de smart city y los efectos que presentan los procesos de dataficación sobre los espacios ur-banos y los individuos. Concluyo con una cita a la figura conceptual del idiota de Isabelle Stengers, enunciando una reflexión crítica sobre la visión de ciudad que contiene el paradigma de la smart city.

This paper examines the potential integration of Living Labs concepts of open and user driven innovation with Future Internet experimentally driven research approaches, in order to accelerate the user-driven development of Future Internet enabled services towards Smart Cities. Two key issues are underlying this integration: strengthening user involvement in experimental Internet research, and providing access to common resources such as testbed facilities and living lab resources. To explore the opportunities for such integration, three case studies from current FP7-ICT projects are discussed: SmartSantander, TEFIS and ELLIOT. A framework is proposed facilitating the sharing of resources offered by existing Smart City platforms, testbeds and living labs facilities as a basis for partnership agreements implementing open innovation approaches for Smart Cities.

There is a growing interest in empirical study in software engineering, both for validating mature technologies and for guiding improvements of less-mature technologies. This paper introduces an empirical methodology, based on experiences garnered over more than two decades of work by the Empirical Software Engineering Group at the University of Maryland and related organizations, for taking a newly proposed improvement to development processes from the conceptual phase through transfer to industry. The methodology presents a series of questions that should be addressed, as well as the types of studies that best address those questions. The methodology is illustrated by a specific research program on inspection processes for Object-Oriented designs. Specific examples of the studies that were performed and how the methodology impacted the development of the inspection process are also described.

Is it possible to reduce the expected response time of every request at a web server, simply by changing the order in which we schedule the requests? That is the question we ask in this paper.This paper proposes a method for improving the performance of web servers servicing static HTTP requests. The idea is to give preference to requests for

The question of when and how international orders change remains a pertinent issue of International Relations theory. This article develops the model of pragmatic ordering to conceptualise change. The model of pragmatic ordering synthesises recent theoretical arguments for a focus on ordering advanced in-practice theory, pragmatist philosophy, and related approaches. It also integrates evidence from recent global governance research. We propose a five-stage model. According to the model, once a new problem emerges (problematisation), informality allows for experimenting with new practices and developing new knowledge (informalisation and experimentation). Once these experimental practices become codified, and survive contestation, they increasingly settle (codification) and are spread through learning and translation processes (consolidation). We draw on the rise of the maritime security agenda as a paradigmatic case and examine developments in the Western Indian Ocean region to illustrate each of these stages. The article draws attention to the substantial reorganisation of maritime space occurring over the past decade and offers an innovative approach for the study of orders and change.

Systematic reviews are generally regarded by professionals in the field of evidence-based medicine as the highest level of medical evidence, and they are already standard practice for clinical studies. However, they are not yet widely used nor undertaken in the field of animal experimentation, even though there is a lot to be gained from the process. Therefore, a gold standard publication checklist (GSPC) for animal studies is presented in this paper. The items on the checklist have been selected on the basis of a literature analysis and the resulting scientific evidence that these factors are decisive in determining the outcome of animal studies. In order to make future systematic reviews and meta-analyses of animal studies possible, to allow others to replicate and build on work previously published, diminish the number of animals needed in animal experimentation (reduction), improve animal welfare (refinement) and, above all, improve the quality of scientific papers on animal exp...

The contribution presents a multi-agent technology in the domain of the air-traffic control of several autonomous aerial vehicles (manned as well as unmanned). The system has been validated mainly by the collision avoidance (CA) tasks. Several cooperative and non-cooperative CA methods have been integrated in the system to validate and compare their properties in the scalable experiments. The AGENTFLY system is suitable also for the developing and testing of algorithms for the collective flight control. The operation of the underlying multi-agent system has been integrated with freely available geographical and tactical data sources. The system provides real time 2D/3D visualization and also the web-access component.
