    Socio-economic projections in urban climate change adaptation planning: Practices and prospects for just adaptation

    Urban climate change adaptation efforts have often been criticized for exacerbating the inequitable impacts of climate change by failing to address the social, economic, and environmental impacts of adaptation. There is an urgent need to incorporate equity and justice concerns in adaptation planning as well as approaches and tools that enable such integration. However, climate justice scholarship to date has largely focused on theoretical questions and there is still a lack of focus on the operational aspects for supporting the implementation of climate justice. In this article, we argue that existing tools already in use in planning practice have the potential to support this aim. In particular, we argue that the integration of socio-economic data into adaptation planning practice could be an avenue for justice-centered urban adaptation. While the potential is clear, how to do this is still underexplored. To shed light on this question, we conduct a systematic review of research on the use of socio-economic projections in urban climate change adaptation planning and decision-making to investigate how these could be used as a tool to ensure just urban adaptation. Grounded in a recognized conceptual framework on urban climate justice, we analyze the evolution of research on socio-economic projections in urban adaptation and evaluate the potential for existing applications to promote climate justice. Through this analysis, we find that while socio-economic projections have not been explicitly linked to justice outcomes in the existing literature, clear potentials exist for these to be used as a tool to promote distributive, procedural, and recognition and restorative justice. Finally, we propose an operational framework for the application of socio-economic projections to promote justice-centered urban adaptation. Applying such a framework to urban adaptation planning can help center justice concerns in larger strategic adaptation planning efforts and enable a new form of more inclusive, data-driven climate governance in cities based on current know-how and existing capacities.MO’s research is funded by the European Union (ERC , IMAGINE adaptation, 101039429 ).

    Contactless 2-dimensional laser sensor for 3-dimensional wire position and tension measurements

    Full text link
    We have developed a contact-free 2-dimensional laser sensor with which the position of wires can be measured in 3 dimensions with an accuracy of better than 10 micrometer and with which the tension of the wires can be determined with an accuracy of 0.04 N. These measurements can be made from a distance of 15 cm. The sensor consists of commercially available laser pointers, lenses, color filters and photodiodes. In our application we have used this laser sensor together with an automated 3 dimensional coordinate table. For a single position measurement, the laser sensor is moved by the 3-dimensional coordinate table in a plane and determines the coordinates at which the wires intersect with this plane. The position of the plane itself (the third coordinate) is given by the third axis of the measurement table which is perpendicular to this plane. The control and readout of the table and the readout of the laser sensor were realized with LabVIEW. The precision of the position measurement in the plane was determined with wires of 0.2 mm and 0.3 mm diameter. We use the sensor for the quality assurance of the wire electrode modules for the KATRIN neutrino mass experiment. We expect that the precision is at least comparable or better if the wires are thinner. Such a device could be well suited for the measurement of wire chamber geometries even with more than one wire layer.Comment: 15 pages, 8 figure

    The KATRIN Experiment

    Full text link
    The KArlsruhe TRitium Neutrino mass experiment, KATRIN, aims to search for the mass of the electron neutrino with a sensitivity of 0.2 eV/c^2 (90% C.L.) and a detection limit of 0.35 eV/c^2 (5 sigma). Both a positive or a negative result will have far reaching implications for cosmology and the standard model of particle physics and will give new input for astroparticle physics and cosmology. The major components of KATRIN are being set up at the Karlsruhe Institut of Technology in Karlsruhe, Germany, and test measurements of the individual components have started. Data taking with tritium is scheduled to start in 2012.Comment: 3 pages, 1 figure, proceedings of the TAUP 2009 International Conference on Topics in Astroparticle and Underground Physics, to be published in Journal of Physics, Conference Serie

    Are fathers a good substitute for mothers? Paternal care and growth rates in Shodagor children

    Get PDF
    Abstract Biparental care is a hallmark of human social organization, though paternal investment varies between and within societies. The facultative nature of paternal care in humans suggests males should invest when their care improves child survival and/or quality, though testing this prediction can be challenging because of the difficulties of empirically isolating paternal effects from those of other caregivers. Additionally, the broader context in which care is provided, vis-à-vis care from mothers and others, may lead to different child outcomes. Here, we examine the effects of paternal care on child growth among Shodagor fisher-traders, where fathers provide high levels of both additive and substitutive care, relative to mothers. We modeled seasonal z-scores and velocities for height, weight, and body mass index (BMI) outcomes using linear mixed models. Our evidence indicates that, as predicted, the context of paternal care is an important predictor of child outcomes. Results show that environmental seasonality and alloparental help contribute to a nuanced understanding of the impact of Shodagor paternal care on child physiology

    The KATRIN Pre-Spectrometer at reduced Filter Energy

    Get PDF
    The KArlsruhe TRItium Neutrino experiment, KATRIN, will determine the mass of the electron neutrino with a sensitivity of 0.2 eV (90% C.L.) via a measurement of the beta-spectrum of gaseous tritium near its endpoint of E_0 =18.57 keV. An ultra-low background of about b = 10 mHz is among the requirements to reach this sensitivity. In the KATRIN main beam-line two spectrometers of MAC-E filter type are used in a tandem configuration. This setup, however, produces a Penning trap which could lead to increased background. We have performed test measurements showing that the filter energy of the pre-spectrometer can be reduced by several keV in order to diminish this trap. These measurements were analyzed with the help of a complex computer simulation, modeling multiple electron reflections both from the detector and the photoelectric electron source used in our test setup.Comment: 22 pages, 12 figure

    Reliability of 3D planning and simulations of medial open wedge high tibial osteotomies

    Purpose: In medial open-wedge high tibial osteotomy (HTO) hinge axis and osteotomy plane influence the resulting anatomy, but accurate angular quantifications using 3D-planning-simulations are lacking. The objectives of this study were developing a standardized and validated 3D-planning method of an HTO and to perform several simulated realignments to explain unintended anatomy changes. Methods: The cutting direction of the main osteotomy was defined parallel to the medial tibial slope and the hinge axis 1.5 cm distal to the lateral plateau. For interobserver testing, this 3D planning was performed on 13 digital models of human tibiae by two observers. In addition, four different hinge axis positions and five differently inclined osteotomy planes each were simulated. The osteotomy direction ranged from medial 0°–30° anteromedial, while the tilt of the osteotomy plane compared to the tibial plateau was −10° to +10°. All anatomic angular changes were calculated using 3D analysis. Results: Multiple HTO plannings by two medical investigators using standardized procedures showed only minimal differences. In the 3D-simulation, each 10° rotation of the hinge axis resulted in a 1.7° significant increase in slope. Tilting the osteotomy plane by 10° resulted in significant torsional changes of 2°, in addition to minor but significant changes in the medial proximal tibial angle (MPTA). Conclusion: Standardized 3D-planning of the HTO can be performed with high reliability using two-observer planning. 3D-simulations suggest that control of the osteotomy plane is highly relevant to avoid unintended changes in the resulting anatomy, but this can be a helpful tool to modify specific angles in different pathologies in the HTO
