    Becoming a (green) identity entrepreneur: learning to negotiate situated identities to nurture community environmental practice

    This paper explores the relationship between ‘green’ identity and community environmental practice. It focuses on the ways in which professional community development facilitators and lead members of community groups attempt to actively shape how environmental projects are locally received. Drawing principally on identity, social sustainability and social practice theory scholarship, it reviews the often very personal and place-specific ways in which appeals to green identity are variously understood and applied, or are actively avoided, by community group leaders. Individuals who have become skilful in negotiating and influencing the presentation of environmental projects to the local community are understood here as (green) identity entrepreneurs. Arguably, it is the situated entrepreneurial skilfulness of lead individuals in negotiating the multiple and evolving (green) identities circulating through any one project, which plays a significant part in determining its subsequent impact and longevity. In understanding the contribution of (green) identity entrepreneurship, however, its relational association with everyday practices, routines and meanings of community and place is brought to the fore. The paper also considers how divergent external interpretations of what constitutes legitimate environmental practice at a local level further shape project identity. The discussion is informed by evidence drawn from a qualitative study of seventeen community groups and seven professional environmental support officers participating in a Welsh Government led programme aimed at facilitating 'community action on climate change'

    Reconstruction of primary vertices at the ATLAS experiment in Run 1 proton–proton collisions at the LHC

    This paper presents the method and performance of primary vertex reconstruction in proton–proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during 2012 at a centre-of-mass energy of √s=8 TeV. The performance has been measured as a function of the number of interactions per bunch crossing over a wide range, from one to seventy. The measurement of the position and size of the luminous region and its use as a constraint to improve the primary vertex resolution are discussed. A longitudinal vertex position resolution of about 30μm is achieved for events with high multiplicity of reconstructed tracks. The transverse position resolution is better than 20μm and is dominated by the precision on the size of the luminous region. An analytical model is proposed to describe the primary vertex reconstruction efficiency as a function of the number of interactions per bunch crossing and of the longitudinal size of the luminous region. Agreement between the data and the predictions of this model is better than 3% up to seventy interactions per bunch crossing

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

    Wilson and Jungner Revisited: Are Screening Criteria Fit for the 21st Century?

    Driven by technological innovations, newborn screening (NBS) panels have been expanded and the development of genomic NBS pilot programs is rapidly progressing. Decisions on disease selection for NBS are still based on the Wilson and Jungner (WJ) criteria published in 1968. Despite this uniform reference, interpretation of the WJ criteria and actual disease selection for NBS programs are highly variable. A systematic literature search [PubMED search “Wilson” AND “Jungner”; last search 16.07.22] was performed to evaluate the applicability of the WJ criteria for current and future NBS programs and the need for adaptation. By at least two reviewers, 105 publications (systematic literature search, N = 77; manual search, N = 28) were screened for relevant content and, finally, 38 publications were evaluated. Limited by the study design of qualitative text analysis, no statistical evaluation was performed, but a structured collection of reported aspects of criticism and proposed improvements was instead collated. This revealed a set of general limitations of the WJ criteria, such as imprecise terminology, lack of measurability and objectivity, missing pediatric focus, and absent guidance on program management. Furthermore, it unraveled specific aspects of criticism on clinical, diagnostic, therapeutic, and economical aspects. A major obstacle was found to be the incompletely understood natural history and phenotypic diversity of rare diseases prior to NBS implementation, resulting in uncertainty about case definition, risk stratification, and indications for treatment. This gap could be closed through the systematic collection and evaluation of real-world evidence on the quality, safety, and (cost-)effectiveness of NBS, as well as the long-term benefits experienced by screened individuals. An integrated NBS public health program that is designed to continuously learn would fulfil these requirements, and a multi-dimensional framework for future NBS programs integrating medical, ethical, legal, and societal perspectives is overdue

    Voices from the field: How did you come to engage in students-as-partners work?

    Get PDF
    The language of students as partners was cemented into higher education (HE) practice and scholarship 10 years ago. While it had been circulating in higher education policy, practices, and publications before that, two key 2014 publications on engaging students as partners, or SaP, inspired a myriad of practices and publications brought together by the relational, values-based ethos of partnership (Cook-Sather et al., 2014; Healey et al., 2014). A seductively simple idea— that students can collaborate with staff as partners on matters of teaching and learning—landed at the right time. The higher education sector was increasingly fixated on student involvement and engagement, particularly on how university changes students (Klemenčič, 2024). SaP offered a related but direction-shifting proposition: what if students could shape higher education

    Empfehlungen zu ethischen, rechtlichen, sozialen und medizinischen Rahmenbedingungen für ein genomisches Neugeborenen-Screening-Programm in Deutschland. Stellungnahme der Projektgruppe NEW_LIVES „Genomic NEWborn screening programs – Legal Implications, Value, Ethics and Society”

    Get PDF
    [English version below] Diese Stellungnahme zielt darauf ab, Empfehlungen für akzeptable Rahmenbedingungen eines Genomischen-Neugeborenen-Screening (gNBS)-Programms in Deutschland zu formulieren, darunter Empfehlungen zu Auswahlkriterien für Zielkrankheiten und zum Management eines gNBS-Programms sowie zur gesetzlichen Neuregulierung. Sie ist Ergebnis eines dreijährigen Forschungsprojektes, das an den Universitäten Heidelberg und Mannheim durchgeführt wurde. An dem interdisziplinären Projekt beteiligt waren Forscher:innen aus den Bereichen Kinder- und Jugendmedizin, Humangenetik, Rechtswissenschaft, Medizinische Psychologie und Medizinethik sowie Vertreter:innen von Patient:innen-Organisationen (Kindernetzwerk e.V. und Deutsche Interessengemeinschaft Phenylketonurie und verwandte angeborene Stoffwechselstörungen e.V.). Das Projekt wurde vom Bundesministerium für Bildung und Forschung (BMBF; seit 2025 Bundesministerium für Forschung, Technologie und Raumfahrt: BMFTR) gefördert und trägt den Titel NEW_LIVES („Genomic NEWborn screening programs – Legal Implications, Value, Ethics and Society” – „Genomische Neugeborenen-Screening-Programme – Rechtliche Implikationen, Werte, Ethik und Gesellschaft“). Die Stellungnahme beginnt mit einführenden Kapiteln zum Hintergrund des gNBS aus Sicht der verschiedenen Fachbereiche und aus Sicht der Gesellschaft, gefolgt von konkreten Empfehlungen für ein zukünftig mögliches gNBS-Pro- gramm in Deutschland. In der Einleitung (1.) werden erste Ergebnisse bisheriger Forschungsprojekte zum gNBS zusammengefasst und die Zielsetzung und Methode, einschließlich der Rolle von Patient:innen-Vertreter:innen bei der Erarbeitung der Stellungnahme werden beschrieben. In Abschnitt 2 („Medizinischer Hintergrund“) werden Entwicklung, Umfang und Ablauf des derzeitigen Neugeborenen-Screening (NBS)-Programms in Deutschland beschrieben und die Besonderheiten eines gNBS-Programms erläutert. Abschnitt 3 („Perspektive von Patient:innen, Eltern und medizinischem Personal“) fasst die Ergebnisse der sozialempirischen Studien zusammen, die im Rahmen des Projektes NEW_LIVES durchgeführt wurden (Fokusgruppen, bevölkerungs-repräsentative Befragung, querschnittliche Online-Befragung) und vergleicht die Ergebnisse mit anderen, internationalen Studien. Abschnitt 3 enthält außerdem eine gemeinsame Stellungnahme der beiden Patient:innen-Organisationen, die am Projekt NEW_LIVES mitgewirkt haben, zum gNBS. Abschnitt 4 („Genomisches Neugeborenen-Screening aus rechtlicher Sicht“) skizziert den rechtlichen Regulierungsrahmen zum gNBS in Deutschland. Abschnitt 5 („Genomisches Neugeborenen-Screening aus ethischer Sicht“) benennt zentrale ethische Herausforderungen des gNBS und formuliert ethische Orientierungsmaßstäbe für ein zukünftiges gNBS-Programm in Deutschland. Da die Neugeborenen diejenigen sind, die an einem gNBS teilnehmen würden und davon profitieren könnten, stellt deren Kindeswohl den zentralen ethischen Orientierungsmaßstab für die Bewertung dar. Die sich in Abschnitt 6 anschließenden Empfehlungen sind aus Sicht aller an der Erarbeitung dieser Stellungnahme beteiligten Fachdisziplinen und der Patient:innen-Organisationen verfasst Darunter sind einerseits transparente Auswahlkriterien für Zielkrankheiten eines gNBS-Programms (Kriterien 1–11). Andererseits werden Empfehlungen für die Einführung, Qualitätssicherung und Nutzenbewertung eines gNBS-Programms formuliert (Kriterien 12–18). Zudem enthält diese Stellungnahme Empfehlungen zur gesetzlichen Neuregulierung. Eine Publikation der Empfehlungen auf Englisch findet sich in Schnabel-Besson et al.: “A multi-dimensional fra- mework for establishing and managing a genomic newborn screening program” (Arbeitstitel; zum Zeitpunkt des Verfassens dieser Stellungnahme in Vorbereitung; DOI der Preprint-Version: 10.1101/2025.06.17.25329 471). - This position paper has the aim of formulating recommendations for what would be an acceptable framework for a genomic newborn screening (gNBS) programme in Germany, including recommendations for selection criteria for target diseases, and for the management of a gNBS programme, as well as for revision of legislation. It is the result of a research project conducted at the Universities of Heidelberg and Mannheim over the course of three years. This interdisciplinary project brought together researchers from the fields of paediatrics and adolescent medicine, human genetics, law, medical psychology, and medical ethics, as well as representatives of patient organisations (Kindernetzwerk e.V., and Deutsche Interessenge- meinschaft Phenylketonurie und verwandte angeborene Stoffwechselstörungen e.V.). The project was funded by the German Federal Ministry of Education and Research (BMBF; since 2025 Federal Ministry of Research, Technology and Space: BMFTR) and is called NEW_LIVES (“Genomic NEWborn screening programs – Legal Implications, Value, Ethics and Society”). The position paper begins with introductory chapters on gNBS from the perspective of the different disciplines, and from a societal viewpoint, followed by concrete recommendations for a possible future gNBS programme in Germany. The Introduction (1.) summarises the initial results of previous research projects on gNBS, and describes the objectives, and methodology, including the role of patient representatives, in the development of the position paper. Section 2 (“Medical Background”) describes the development, scope, and process of the current NBS programme in Germany, and explains the specific features of a gNBS programme. Section 3 (“Perspectives of Patients, Parents, and Medical Staff”) summarizes the results of the social-empirical studies conducted as part of the NEW_LIVES project (focus groups, population-representative survey, cross-sectional online survey), and compares the results with other, international studies. Section 3 also contains a joint statement on gNBS by the two patient organisations that participated in the NEW_LIVES project. Section 4 (“Genomic Newborn Screening from a Legal Perspective”) outlines the legal regulatory framework for gNBS in Germany. Section 5 (“Genomic Newborn Screening from an Ethical Perspective”) identifies key ethical challenges of gNBS, and formulates ethical guidelines for a future gNBS programme in Germany. Since newborns are the ones who would participate in, and benefit from gNBS, their welfare represents the central ethical guideline for the evaluation. The recommendations in Section 6 are written from the perspective of all disciplines, and patient organisations involved in the development of this position paper. These recommendations reflect the consensus of the inter-, and transdisciplinary group of authors, and form the core of the position paper. They comprise 18 criteria for a possible future gNBS programme in Germany. These include, on the one hand, transparent selection criteria for target diseases of a gNBS programme (criteria 1–11). On the other hand, recommendations are formulated for the introduction, quality assurance, and benefit assessment of a gNBS programme (criteria 12–18). This position paper also contains recommendations for new legal regulations. An English version of the recommendations, including the 11 criteria for selecting target diseases and the 7 criteria for programme management can be found in Schnabel-Besson E, Dikow N, Alex K et al.: “A multidimensional framework for establishing and managing a genomic newborn screening program” (working title; in preparation at the time of writing this position paper; doi of preprint version: 10.1101/2025.06.17.25329471)

    Two high-risk susceptibility loci at 6p25.3 and 14q32.13 for Waldenström macroglobulinemia

    Waldenström macroglobulinemia (WM)/lymphoplasmacytic lymphoma (LPL) is a rare, chronic B-cell lymphoma with high heritability. We conduct a two-stage genome-wide association study of WM/LPL in 530 unrelated cases and 4362 controls of European ancestry and identify two high-risk loci associated with WM/LPL at 6p25.3 (rs116446171, near EXOC2 and IRF4; OR = 21.14, 95% CI: 14.40–31.03, P = 1.36 × 10 −54 ) and 14q32.13 (rs117410836, near TCL1; OR = 4.90, 95% CI: 3.45–6.96, P = 8.75 × 10 −19 ). Both risk alleles are observed at a low frequency among controls (~2–3%) and occur in excess in affected cases within families. In silico data suggest that rs116446171 may have functional importance, and in functional studies, we demonstrate increased reporter transcription and proliferation in cells transduced with the 6p25.3 risk allele. Although further studies are needed to fully elucidate underlying biological mechanisms, together these loci explain 4% of the familial risk and provide insights into genetic susceptibility to this malignancy. © 2018, The Author(s).Peer reviewe

    Searching for IceCube sub-TeV neutrino counterparts to sub-threshold Gravitational Wave events

    Get PDF
    Since the release of the Gravitational Wave Transient Catalogue GWTC-2.1 by the LIGO-Virgo collaboration, sub-threshold gravitational wave (GW) candidates are publicly available. They are expected to be released in real-time as well, in the upcoming O4 run. Using these GW candidates for multi-messenger studies complement the ongoing efforts to identify neutrino counterparts to GW events. This in turn, allows us to schedule electromagnetic follow-up searches more efficiently. However, the definition and criteria for sub-threshold candidates are pretty flexible. Finding a multi-messenger counterpart via archival studies for these candidates will help to set up strong bounds on the GW parameters which are useful for defining a GW signal as sub-threshold, thereby increasing their significance for scheduling follow-up searches. Here, we present the current status of this ongoing work with the IceCube Neutrino Observatory. We perform a selection of the sub-threshold GW candidates from GWTC-2.1 and conduct an archival search for sub-TeV neutrino counterparts detected by the dense infill array of the IceCube Neutrino Observatory, known as "DeepCore". For this, an Unbinned Maximum Likelihood (UML) method is used. We report the 90% C.L. sensitivities of this sub-TeV neutrino dataset for each selected sub-threshold GW candidate, considering the spatial and temporal correlation between the GW and neutrino events within a 1000 s time window
