    Enemies or Colleagues? the 15M and the Podemos hipothesys

    Get PDF
    Through an ethnography and participant observation in Madrid, Malaga and Cordoba about 15M (since 2011) and Podemos (since 2014) the article analyzes the tensions that cross the attempted to take the indignant movement to political institutions. We show that these tensions are understood from the place and the meaning of consensus in the movement of the indignados, partially hidden by the criticism of the lack of effectiveness of the movement and its refusal to adopt a political strategy based on the institutional representation. Through consensus, the 15M unveils, besides the concept of Multitude to which was primarily associated, an irrepresentable imaginary of a society of equals. If we understand the consensus as the key element of indignados political significance, we wonder how the hegemonic translation proposed by Podemos could be claimed from that imaginary

    The Oxyspinel group End-Member Generator (OxyEMG) is an improved version of the EMG application. This new version allows for calculating, based on electron microprobe analysis (EMPA), the proportions of 31 end-member components in an oxyspinel composition. These components are MgAl2O4 (spinel), FeAl2O4 (hercynite), MnAl2O4 (galaxite), ZnAl2O4 (gahnite), NiAl2O4 (chihmingite), CuAl2O4 (thermaerogenite), MgFe2O4 (magnesioferrite), Fe3O4 (magnetite), MnFe2O4 (jacobsite), ZnFe2O4 (franklinite), NiFe2O4 (trevorite), CuFe2O4 (cuprospinel), FeMn2O4, MgMn2O4, Mn3O4 (hausmannite), ZnMn2O4 (hetaerolite), MgCr2O4 (magnesiochromite), FeCr2O4 (chromite), MnCr2O4 (manganochromite), ZnCr2O4 (zincochromite), NiCr2O4 (nichromite), CoCr2O4 (cochromite), MgV2O4 (magnesiocoulsonite), FeV2O4 (coulsonite), MnV2O4 (vuorelainenite), Co3O4 (guite), TiMg2O4 (qandilite), TiFe2O4 (ulvöspinel), SiMg2O4 (ringwoodite), SiFe2O4 (ahrensite) and GeFe2O4 (brunogeierite). Compared with the older version, OxyEMG allows for (a) calculating 12 additional oxyspinel group end-member compositions (chihmingite, thermaerogenite, hausmannite, hetaerolite, FeMn2O4, MgMn2O4, cuprospinel, cochromite, guite, ringwoodite, ahrensite and brunogeierite), (b) discriminating the cation valency not only for Fe2+–Fe3+ but also for Mn2+–Mn3+ and Co2+–Co3+, and (c) changing the method to calculate the components of the magnetite and ulvöspinel prisms. As in EMG, this new version is an application that does not require an installation process and was created with the purpose of performing calculations to obtain cation proportions (per formula unit, p.f.u.), end-members of the oxyspinel group, a ΣR3+ value, a ΣR2+ value, ΣR3+ / ΣR2+ ratios, redistribution proportions for the corresponding end-members in the magnetite or ulvöspinel prisms, and a data validation section to check the results.</p

    Risk Assessment Methodologies to Safeguard Historic Urban Areas from the Effects of Climate Change

    A systematic and critical review of the existing literature on climate-change riskassessment methodologies for historic urban areas is presented, in view of the increasing likelihood of extreme weather events. Key performance indicators are identified for use in future risk assessment methodologies that address both the elements of historic urban areas as a system and the potential impact of prolonged heat waves. To do so, a systematic search of the existing literature on Web of Science and Scopus was conducted, with the aim of identifying and characterizing existing methodologies on vulnerability and risk assessment for cultural heritage exposed to the effects of a changing climate. The main characteristics of the methodologies that need to be addressed in the near future and key knowledge gaps were identified, among them, the lack of holistic heat-wave risk-assessment methodologies for historic urban areas

    Participatory budgeting, community engagement and impact on public services in Scotland

    Get PDF
    The institutional engagement and analysis needed to effectively integrate the requirements of equality legislation into participatory budgeting (PB) processes requires a transformational approach. Equality processes appear to exist in parallel with PB activity, rather than being operationalized as integral to the objectives and character of PB activity at local level. This paper proposes that PB and the Public Sector Equality Duty (PSED) in the Equality Act 2010 share a transformative intent and potential, but that this is undermined by siloed thinking on equalities and enduring discriminatory behaviour and practices. The paper concludes with propositions for aligning the conceptual links between equality and community empowerment and, thereby, participation in local financial decision-making in practice

    Designing effective public participation

    Get PDF
    This paper reviews the various connections that can exist between the design of participatory processes and the different kind of results that they can entail. It details how effective participatory processes can be designed, whatever are the results that participation is deemed to elicit. It shows the main trends pertaining to design choicesand considers how to classify different arrangements in order to choose from among them. Then the paper deals with the main dilemmas that tend to arise when designing participatory processes. Thanks to this review, the paper argues that participatory processes tend to display a certain degree of ambivalence that cannot be completely overcome through the design choices

    Scale-up and large-scale production of Tetraselmis sp CTP4 (Chlorophyta) for CO2 mitigation: from an agar plate to 100-m(3) industrial photobioreactors

    Industrial production of novel microalgal isolates is key to improving the current portfolio of available strains that are able to grow in large-scale production systems for different biotechnological applications, including carbon mitigation. In this context, Tetraselmis sp. CTP4 was successfully scaled up from an agar plate to 35-and 100-m(3) industrial scale tubular photobioreactors (PBR). Growth was performed semi-continuously for 60 days in the autumn-winter season (17th October -14th December). Optimisation of tubular PBR operations showed that improved productivities were obtained at a culture velocity of 0.65-1.35 m s(-1) and a pH set-point for CO2 injection of 8.0. Highest volumetric (0.08 +/- 0.01 g L-1 d(-1)) and areal (20.3 +/- 3.2 g m(-2) d(-1)) biomass productivities were attained in the 100-m(3) PBR compared to those of the 35-m(3) PBR (0.05 +/- 0.02 g L-1 d(-1) and 13.5 +/- 4.3 g m(-2) d(-1), respectively). Lipid contents were similar in both PBRs (9-10% of ash free dry weight). CO2 sequestration was followed in the 100-m(3) PBR, revealing a mean CO2 mitigation efficiency of 65% and a biomass to carbon ratio of 1.80. Tetraselmis sp. CTP4 is thus a robust candidate for industrial-scale production with promising biomass productivities and photosynthetic efficiencies up to 3.5% of total solar irradiance.Portuguese national budget; Foundation for Science and Technology (FCT) [CCMAR/Multi/04326/2013]; INTERREG V-A Espana-Portugal project [0055 ALGARED + 5 E]; COST Action - European Network for Bio-products [1408]; FCT [SFRH/BD/105541/2014]; Nord Universityinfo:eu-repo/semantics/publishedVersio
