Recently, computational methods and software have been receiving more attention in the econometrics literature, emphasizing that they are integral components of modern econometric research. This has also promoted the development of many new econometrics software packages written in R and made available on the Comprehensive R Archive Network. This special volume on "Econometrics in R" features a selection of these recent activities that includes packages for econometric analysis of cross-section, time series and panel data. This introduction to the special volume highlights the contents of the contributions and embeds them into a brief overview of other past, present, and future projects for econometrics in R.

Detta är ett projekt om en förskola i Gamla Hagalund i Solna norr om Stockholm. Området är det äldsta i Solna, präglat av historia och personlighet. Detta är ett förslag till en förskola, som med sina naturliga material smältar in i omgivningen bestående av gamla trävillor. Skolan tar utgångspunkt i Open-Air skolans koncept om att en nära kontakt med naturen främjar elevens hälsa. / This is a project about a preschool in Gamla Hagalund in Solna north of Stockholm. The area is the oldest in Solna, characterized by history and personality. This is a proposal for a preschool that with its natural materials melts into the surroundings consisting of old wooden villas. The school is based on the concept of the Open-Air School believing that a close contact with nature promotes the health of the student.

Research within the last fifteen years on global advocacy networks has often focused on their accomplishments through the linking of similar groups. The majority of this research while being useful to examine transnational political dynamics has two deficiencies. The first is that there is little or no consideration of the network infrastructure (from code to cables) that allows the aforementioned linkage to occur. It is therefore important to investigate the politics of infrastructure, architecture and design and the power and control thereof. Secondly, prior to Web 2.0. technologies, advocacy networks were nodes of information distribution, rather than nodes to which information was directed, and then subsequently collected, compiled and used for political purposes. It is quite reasonable to argue that Web 2.0. technologies (again due to considerations of code, digital architecture and design) have altered the manner in advocacy networks interact with their supporters, other organizations and formal political institutions. This change is located within the advocacy network’s technoorganizational structure. Subsequently, as the digital architecture for the internet is an inter-operable free/libre open source software (FLOSS) common to information exchange, it stands to reason that as an infrastructure this technology is directly a political landscape over which and in which friction and contestation can and does occur. In regard to the methods of interaction, FLOSS technologies have greatly expanded the pool of potential social activists and reduced the costs of engagement, activism and highlighting issues. With these factors in mind it can be argued that FLOSS has created opportunities for civil society to emerge and engage with society at large in ways that are both new (in a digital medium) and similar (tackling issues of social justice as constructed by the social activists). When considered at a systematic level this process has several implications. These implications include the impact of 4 networking on identity, social relations, power relations and so on, which in turn acknowledges that modern computer networking can act as a mechanism that radically restructures various political relations. This itself acknowledges various contests over modern computer networking (one position which is expressed by various FLOSS proponents), and the physical infrastructure and the power and control thereof which allows such networking to even exist in the first instance. Within this context, which could be described as an information ecosystem, there is a recognition that advocacy networks have emerged as new sources of power ready to exert influence through networking that occurs in a) a non formal manner and b) ‘beneath the radar’ as it were.

The purpose of this experiment has been to complete a challenging thesis production in the style and technique of Open Theatre, utilizing imaginative production effects. The purpose was also to provide a valuable experience for those actors and technicians involved, meeting the standards and requirements of educational theatre. The experiment evolved from adapting, designing, directing, and producing a twelve-scene cutting from Megan Terry's Viet Rock and twelve episodes from Jean-Claude van Itallie's The Serpent.

Dans cette thèse, nous proposons de nouvelles approches et processus de conception pour créer et produire des plates-formes robotiques dont le contrôle et la morphologie peuvent être explorés et expérimentés librement dans le monde réel, tout en assurant une dissémination directe dans le milieu académique. Ainsi cette thèse adresse deux questions fondamentales dans le processus de recherche scientifique en robotique:1. Comment peut on étudier systématiquement et efficacement l’impact des propriétés morphologiques du corps d’un robot humanoïde pour l’acquisition et le contrôle de savoir-faire sensorimoteurs, ainsi que de capacités d’interactions physiques et sociales avec l’humain ?2. Comment peut on produire des contributions scientifiques en robotique qui soient réellement reproductibles et directement réutilisables, tout en exposant les moindres détails des expérimentations ? Ainsi notre approche propose de nouvelles méthodes de conception et de production, et ce, pour tous les aspects technologiques d’un robot (mécanique, actionneur,électronique, logiciels, distribution). En particulier, ces méthodes reposent sur l’impression 3D pour toutes les pièces mécaniques, un environnement Arduino pour l’acquisition des capteurs, une bibliothèque Python appelée pypot pour le contrôle proposant un API intuitive et enfin la distribution de tout notre travail sous des licences open source.En utilisant cette méthodologie, nous avons créé le robot Humanoïde Poppy, un robotlow-cost, entièrement modulaire et imprimé en 3D. Ce robot est diffusé sous licence open source et tous les fichiers sont facilement accessibles sur le dépôt GitHub du projet: https://www.github.com/poppy_project/.Nous expérimentons l’utilisation de ce robot pour plusieurs applications. Tout d’abord, comme un outil scientifique où nous montrons que Poppy peut être facilement et rapidement modifié, que ce soit pour explorer le rôle de la morphologie ou pour être adaptés à différentes configurations expérimentales. Basé sur ce travail, mais d’un autre point de vue, nous étudions aussi l’impact potentiel d’une telle plate-forme pour des applications éducatives et artistiques. / This thesis suggests novel approaches and design processes to create and produce robotic platforms, the control and morphology of which can be freely explored through experimentation in the real world, that are easy to diffuse and reproduce in the research community. Especially, this alternative design methodology is driven by the desire to:• freely explore morphological properties,• reduce the amount of time required between an idea and its experimentation on an actual robotic platform in the real world,• makes experiments that should be easy to do, actually easy to do,• make the work easily reproducible in any other lab,• keep the work modular and free to use in accordance with open source principles,so it can be reused and extended for other projects.Our approach follows novel design methods for both design and production, for all technological aspects of the robot (i.e. mechanics, actuation, electronics, software,distribution). In particular these methods relies on 3D printing for all mechanical parts, the Arduino electronic architecture for the sensors acquisition, an easy to use Python API called pypot for the control and finally the distribution of all our work under open source licenses. Using this methodology, we create the Poppy Humanoid robot, a fully modular robot allowing exploring freely the role of morphology and adapting its body to specific experimental setup. This robot has been released under open source license and all files are easily accessible on the GitHub repository: https://www.github.com/poppy_project/. We experiment the use of this robot for several applications. First, as a scientific tool and we show that Poppy can be easily and quickly modified to either explore the role of morphology or to be adapted to different experimental setups. Based on this work, but from another perspective we investigate the potential impact of such platform for educational and artistic applications.
