    The third Open Source Geospatial Research & Education Symposium (OGRS) was held in Helsinki, Finland, on 10 to 13 June 2014. The symposium was hosted and organized by the Department of Civil and Environmental Engineering, Aalto University School of Engineering, in partnership with the OGRS Community, on the Espoo campus of Aalto University. These proceedings contain the 20 papers presented at the symposium. OGRS is a meeting dedicated to exchanging ideas in and results from the development and use of open source geospatial software in both research and education.  The symposium offers several opportunities for discussing, learning, and presenting results, principles, methods and practices while supporting a primary theme: how to carry out research and educate academic students using, contributing to, and launching open source geospatial initiatives. Participating in open source initiatives can potentially boost innovation as a value creating process requiring joint collaborations between academia, foundations, associations, developer communities and industry. Additionally, open source software can improve the efficiency and impact of university education by introducing open and freely usable tools and research results to students, and encouraging them to get involved in projects. This may eventually lead to new community projects and businesses. The symposium contributes to the validation of the open source model in research and education in geoinformatics

    From the Laboratory to the Classroom: The Potential of Functional Near-Infrared Spectroscopy in Educational Neuroscience

    Get PDF
    Paralleling two decades of growth in the emergent field known as educational neuroscience is an increasing concern that educational practices and programs should be evidence-based, however, the idea that neuroscience could potentially influence education is controversial. One of the criticisms, regarding applications of the findings produced in this discipline, concerns the artificiality of neuroscientific experiments and the oversimplified nature of the tests used to investigate cognitive processes in educational contexts. The simulations may not account for all of the variables present in real classroom activities. In this study, we aim to get a step closer to the formation of data-supported classroom methodologies by employing functional near-infrared spectroscopy in various experimental paradigms. First, we present two hyperscanning scenarios designed to explore realistic interdisciplinary contexts, i.e., the classroom. In a third paradigm, we present a case study of a single student evaluated with functional near-infrared spectroscopy and mobile eye-tracking glasses. These three experiments are performed to provide proofs of concept for the application of functional near-infrared spectroscopy in scenarios that more closely resemble authentic classroom routines and daily activities. The goal of our study is to explore the potential of this technique in hopes that it offers insights in experimental design to investigate teaching-learning processes during teacher-student interactions

    Die vorliegende Masterarbeit untersucht aktuelle Trends in der Stadtplanung und Design, um zu analysieren, wie Bürger an der Mitgestaltung von Smart Cities beteiligt werden können. Ziel ist es, ein ganzheitliches Verständnis der neueren Konzepte und Methoden von Co-Design und Co-creation zu entwickeln und diese mit den etablierteren Forschungsfeldern der Bürgerbeteiligung und Koproduktion zu vergleichen. Koproduktion und Co-Creation können als verbesserte Partizipation oder Partnerschaft in Bezug auf die Partizipationsleiter verstanden werden, da beide Konzepte Beziehungen auf Augenhöhe zwischen Bürger und Stadtverwaltung voraussetzen. In ähnlicher Weise gesteht Co-Design, Designern und Usern die gleichen Rechte und Möglichkeiten im Gestaltungsprozess zu. Es wird eine ganzheitliche Definition des Co-Creation-Prozesses dargelegt, die Erkenntnisse aus Co-Design, Co-Produktion und Partizipation beinhaltet und Co-Creation als einen Prozess versteht, der aus Initiation, Design und Produktion besteht. Die Smart City als sich rasch entwickelndes Forschungsfeld, Definitionen und Charakteristika sowie populäre imaginäre und dominante Diskurse werden vorgestellt. Um die Rolle des Bürgers zur Smart City zu verstehen, werden die unterschiedlichen Verständnisse von Smart Governance erläutert und Aspekte von Open Data, Big Data und Big Data Analytics sowie die Rolle von Bürgern und Gefahren der Smart City diskutiert. In der Fallstudie zur Bürgerbeteiligung werden Methoden und Werkzeuge zur Förderung der Mitgestaltung einer Smart City anhand Partizipationsleiter von (Arnstein 1969) diskutiert und analysiert. Die Smart City Entwicklung in Barcelona wird vor dem Hintergrund der gemeinschaftlichen Entwicklung sozialer Innovationen in Smart Cities analysiert. Die Fallstudie verweist auf Mängel im Hinblick auf Bürgerbeteiligung an der Entscheidungsfindung und an der Verlagerung von Machtverhältnissen in der Entwicklung der Smart City Barcelona, die dafür aber mit neuen Werkzeugen und Technologien für partizipative Stadtentwicklung experimentiert und sich zu einem alternativen Smart City Modell entwickelt. Die wichtigsten Ergebnisse sind abschließend im Methodenkatalog zusammengefasst, der Methoden und Tools aus Theorie und Fallstudie aufgreift um zu dem Verständnis beizutragen, wie Smart Cities gemeinsam gestaltet werden können.This thesis studies current trends in planning and design studies to analyse how citizens can participate in the co-creation of smart cities. It aims at developing a holistic understanding of the new concepts and methods of co-creation, and co-design and compares those with the more established research fields of citizen participation and co-production. Co-production and co-creation can be understood as instances of enhanced participation or as a partnership in participation, as both concepts require equal relationships among citizens and the city administration. Similarly, co-design requires designers and users to share the same rights and possibilities in the design process. A holistic definition of the co-creation process is provided that incorporates insights from co-design, co-production and participation and defines co-creation as a process consisting of initiation, design and production. The smart city as emerging research field, definitions and characteristics, as well as popular imaginary and dominant discourses, are presented. To grasp the role of the citizen in the smart city, the different understandings of smart governance are explained and aspects of to open data, big data and big data analytics, as well as the role of citizens and perils of the smart city are discussed. In the case-study of citizen participation methods and tools fostering the co-creation of a smart city are discussed and analysed with the introduced participation framework, which is based on the ladder of participation (Arnstein 1969). The smart city development in Barcelona is analysed against the backdrop of co-creating social innovations in smart cities. There might be a lack of citizen participation in decision-making and shifting power relations in the city, which experiments nonetheless with new tools and technologies for the participatory environment experiments with new formats and technologies for economic and urban development and evolves to become an alternative model of the smart city. The main findings are included in the toolbox based on methods and tools from theory and the case-study contributing to the knowledge of how to co-create of smart cities

    International audienceSince its introduction, the Internet of Things (IoT) has changed several aspects of our lives, leading to the commercialization of different heterogeneous devices. In order to bridge the gap among these heterogeneous devices, in some of the most common IoT use cases -e.g., smart home, smart buildings, etc.-the presence of a gateway as an enabler of interoperability is required. In this paper, we introduce the concept of a Gateway-as- a-Service (GaaS), a lightweight device that can be shared between different users thanks to the use of virtualization techniques.Performance has been evaluated on real hardware and results demonstrate the lightweight characteristics of the proposal

    Changes in Cardiovascular Disease Risk Factors With Immediate Versus Deferred Antiretroviral Therapy Initiation Among HIV-Positive Participants in the START (Strategic Timing of Antiretroviral Treatment) Trial

    Introduction-HIV infection and certain antiretroviral therapy (ART) medications increase atherosclerotic cardiovascular disease risk, mediated, in part, through traditional cardiovascular disease risk factors. Methods and Results-We studied cardiovascular disease risk factor changes in the START (Strategic Timing of Antiretroviral Treatment) trial, a randomized study of immediate versus deferred ART initiation among HIV-positive persons with CD4+ cell counts >500 cells/mm(3). Mean change from baseline in risk factors and the incidence of comorbid conditions were compared between groups. The characteristics among 4685 HIV-positive START trial participants include a median age of 36 years, a CD4 cell count of 651 cells/mm(3), an HIV viral load of 12 759 copies/mL, a current smoking status of 32%, a median systolic/diastolic blood pressure of 120/76 mm Hg, and median levels of total cholesterol of 168 mg/dL, low-density lipoprotein cholesterol of 102 mg/dL, and high-density lipoprotein cholesterol of 41 mg/dL. Mean follow-up was 3.0 years. The immediate and deferred ART groups spent 94% and 28% of follow-up time taking ART, respectively. Compared with patients in the deferral group, patients in the immediate ART group had increased total cholesterol and low-density lipoprotein cholesterol and higher use of lipid-lowering therapy (1.2%;95% CI, 0.1-2.2). Concurrent increases in high-density lipoprotein cholesterol with immediate ART resulted in a 0.1 lower total cholesterol to high-density lipoprotein cholesterol ratio (95% CI, 0.1-0.2). Immediate ART resulted in 2.3% less BP-lowering therapy use (95% CI, 0.9-3.6), but there were no differences in new-onset hypertension or diabetes mellitus. Conclusions-Among HIV-positive persons with preserved immunity, immediate ART led to increases in total cholesterol and lowdensity lipoprotein cholesterol but also concurrent increases in high-density lipoprotein cholesterol and decreased use of blood pressure medications. These opposing effects suggest that, in the short term, the net effect of early ART on traditional cardiovascular disease risk factors may be clinically insignificant.

    The Emergence of New and Successful Export Activities in Brazil: Four Case Studies from the Manufacturing and the Agricultural Sector

    Get PDF
    This paper investigates the emergence of new successful export activities in Brazil through the analysis of four industry case studies: furniture, swimwear, soybeans and grapes. Extensive secondary data research was done to study industries’ historical development and to understand the elements that affect the discovery of new export-oriented activities and their diffusion in the economy. Detailed analysis was carried out to identify the role of public sector in the discovery and diffusion process, if any. Comparison of the four experiences show different models of diffusion and demonstrate how barriers to discovery, spillovers and institutions responses varied dramatically among the cases. The paper tries to extract some general conclusions concerning the role of pioneer firms, external actors and public sector institutions. Some lessons learned are presented aiming to help policymakers to design positive policy interventions in Latin America countries.
