    Covert repertoires: ecotage in the UK

    Get PDF
    Ecological sabotage (ecotage) has been a feature of the more radical parts of the environmental movement in the Western world for several decades. While it may be perceived as being the preserve of underground cells of 'eco-terrorists', in the UK those who carry out small-scale acts of sabotage are also often engaged in relatively conventional political activity; view sabotage as a complement to other action, not as an end in itself; and are committed to avoiding physical harm to people. Drawing on ethnographic data from research with British activists, this article seeks to define ecotage and to explain its place in the repertoires of the environmental direct action movement in the UK. It is argued that the self-limiting form of ecotage in the UK has its roots in cross-movement debates that have developed over several decades and that national traditions remain important in understanding the development of social movement repertoires

    Explaining the fuel protests

    Get PDF
    We describe and analyse the fuel protests in the UK in September and November 2000. We draw on theories of social movements to explain the success of the first of these protests and the failure of the second. We show how the loose, network forms of organisation contributed to the success in September, and the attempts to impose more formal organisations helped to cause the failure in November. We also show how the success of the protests depended on the articulation of the aims of the protestors with dominant social forces in British politics, in particular the oil companies, the police, and the mass media

    Urban Growth Strategies in Rural Regions: Building The North Wales Growth Deal

    Get PDF
    This paper discusses the creation of a growth deal for North Wales (The North Wales Growth Deal – NWGD). North Wales is primarily a rural region within the UK, without a core-city or large metropolitan centre. The paper examines how this urban dynamic, fostered around a pushing of the agglomerative growth model out of the city-region, is being transferred largely across rural space and place in terms of how growth is envisioned and how policy is implemented. It contributes to regional studies knowledge by raising the importance of the non-metropolitan city-regional alternatives in the context of the (academic and policy) city-regional debate

    Measurement of the Multi-Neutron νˉμ\bar{\nu}_{\mu} Charged Current Differential Cross Section at Low Available Energy on Hydrocarbon

    Neutron production in antineutrino interactions can lead to bias in energy reconstruction in neutrino oscillation experiments, but these interactions have rarely been studied. MINERvA previously studied neutron production at an average antineutrino energy of ~3 GeV in 2016 and found deficiencies in leading models. In this paper, the MINERvA 6 GeV average antineutrino energy data set is shown to have similar disagreements. A measurement of the cross section for an antineutrino to produce two or more neutrons and have low visible energy is presented as an experiment-independent way to explore neutron production modeling. This cross section disagrees with several leading models' predictions. Neutron modeling techniques from nuclear physics are used to quantify neutron detection uncertainties on this result.Comment: 25 pages, 11 figures; Added ancillary files with cross section values as .csv Matches preprint accepted by publishe

    Forensic DNA databases in European countries: is size linked to performance?

    Get PDF
    The political and financial investments in the implementation of forensic DNA databases and the ethical issues related to their use and expansion justify inquiries into their performance and general utility. The main function of a forensic DNA database is to produce matches between individuals and crime scene stains, which requires a constant input of individual profiles and crime scene stains. This is conditioned, among other factors, by the legislation, namely the criteria for inclusion of profiles and the periods of time and conditions for their retention and/or deletion. This article aims to provide an overview of the different legislative models for DNA databasing in Europe and ponder if wider inclusion criteria – and, consequently, database size – translates into more matches between profiles of crime scene stains and included individuals (performance ratio). The legislation governing forensic DNA databases in 22 countries in the European Union was analysed in order to propose a typology of two major groups of legislative criteria for inclusion/retention of profiles that can be classified as having either expansive effects or restrictive effects. We argue that expansive criteria for inclusion and retention of profiles do not necessarily translate into significant gains in output performance.MES -Ministry of Education and Science(SFRH/BPD/34143/2006)info:eu-repo/semantics/publishedVersio

    Simultaneous measurement of muon neutrino quasielastic-like cross sections on CH, C, water, Fe, and Pb as a function of muon kinematics at MINERvA

    Get PDF
    This paper presents the first simultaneous measurement of the quasielastic-like neutrino-nucleus cross sections on C, water, Fe, Pb and scintillator (hydrocarbon or CH) as a function of longitudinal and transverse muon momentum. The ratio of cross sections per nucleon between Pb and CH is always above unity and has a characteristic shape as a function of transverse muon momentum that evolves slowly as a function of longitudinal muon momentum. The ratio is constant versus longitudinal momentum within uncertainties above a longitudinal momentum of 4.5GeV/c. The cross section ratios to CH for C, water, and Fe remain roughly constant with increasing longitudinal momentum, and the ratios between water or C to CH do not have any significant deviation from unity. Both the overall cross section level and the shape for Pb and Fe as a function of transverse muon momentum are not reproduced by current neutrino event generators. These measurements provide a direct test of nuclear effects in quasielastic-like interactions, which are major contributors to long-baseline neutrino oscillation data samples.Comment: 9 pages, 8 flgures, including supplemental materia

    Neutrino-induced coherent π+\pi^{+} production in C, CH, Fe and Pb at ⟨Eν⟩∼6\langle E_{\nu}\rangle \sim 6 GeV

    Full text link
    MINERvA has measured the νμ\nu_{\mu}-induced coherent π+\pi^{+} cross section simultaneously in hydrocarbon (CH), graphite (C), iron (Fe) and lead (Pb) targets using neutrinos from 2 to 20 GeV. The measurements exceed the predictions of the Rein-Sehgal and Berger-Sehgal PCAC based models at multi-GeV νμ\nu_{\mu} energies and at produced π+\pi^{+} energies and angles, Eπ>1E_{\pi}>1 GeV and θπ<10∘\theta_{\pi}<10^{\circ}. Measurements of the cross-section ratios of Fe and Pb relative to CH reveal the effective AA-scaling to increase from an approximate A1/3A^{1/3} scaling at few GeV to an A2/3A^{2/3} scaling for Eν>10E_{\nu}>10 GeV

    Simultaneous measurement of muon neutrino νμ\nu_\mu charged-current single π+\pi^+ production in CH, C, H2_2O, Fe, and Pb targets in MINERvA

    Full text link
    Neutrino-induced charged-current single π+\pi^+ production in the Δ(1232)\Delta(1232) resonance region is of considerable interest to accelerator-based neutrino oscillation experiments. In this work, high statistics differential cross sections are reported for the semi-exclusive reaction νμA→μ−π++\nu_\mu A \to \mu^- \pi^+ + nucleon(s) on scintillator, carbon, water, iron, and lead targets recorded by MINERvA using a wide-band νμ\nu_\mu beam with \left \approx 6~GeV. Suppression of the cross section at low Q2Q^2 and enhancement of low TπT_\pi are observed in both light and heavy nuclear targets compared to phenomenological models used in current neutrino interaction generators. The cross-section ratios for iron and lead compared to CH across the kinematic variables probed are 0.8 and 0.5 respectively, a scaling which is also not predicted by current generators.Comment: 6 pages, 6 figures, 117 pages of supplementary material; submitted to Physical Review Letter
