Survivor-led guidelines for conducting trauma-informed psychological therapy assessments: Development and modified Delphi study.

BACKGROUND: Psychological therapy assessments are a key point at which a person is accepted into a service or referred on. There is evidence of service users experiencing harm, dropping out of services and potentially experiencing poor outcomes because of inadequate assessment practices. Approaches to assessment tend to be developed by individual services, with a lack of research identifying what makes a good assessment. METHODS: This survivor-led study, based in England, aimed to generate guidelines for conducting trauma-informed psychological therapy assessments. The study was guided by a Service User Advisory Group and a Clinician Advisory Group. The study was conducted in three key stages: (i) identifying, modelling and drafting guideline content (ii) modified Delphi study and (iii) guideline finalization. Stage 1 was informed by literature reviews, qualitative research, data workshops with Advisory Groups and an expert consultation. Fifty-nine people with relevant experiences then participated in a single-stage modified Delphi (Stage 2). The guidelines were finalized through an analysis of Delphi open comments and a final expert consultation (Stage 3). RESULTS: The guidelines evolved through each stage of the process, and all items were deemed important by >90% of Delphi participants. The final trauma-informed guidelines contain eight principles, including 'focus on relationships', 'from systems to people' and 'healing environments'. CONCLUSIONS: Experiential knowledge was key in generating the guidelines and conceptualizing content, with a consequent focus on areas, such as recognizing power differentials, understanding oppression as trauma and the relational aspects of assessments. Future research should focus on guideline implementation and investigate whether this impacts service user dropout, engagement with therapy, and outcomes. PATIENT OR PUBLIC CONTRIBUTION: This study is an example of survivor research, with several authors, including the study lead, identifying as survivors. We consider the ways in which our identities as survivor researchers impacted the study findings

First-principles study of As interstitials in GaAs: Convergence, relaxation, and formation energy

Convergence of density-functional supercell calculations for defect formation energies, charge transition levels, localized defect state properties, and defect atomic structure and relaxation is investigated using the arsenic split interstitial in GaAs as an example. Supercells containing up to 217 atoms and a variety of {\bf k}-space sampling schemes are considered. It is shown that a good description of the localized defect state dispersion and charge state transition levels requires at least a 217-atom supercell, although the defect structure and atomic relaxations can be well converged in a 65-atom cell. Formation energies are calculated for the As split interstitial, Ga vacancy, and As antisite defects in GaAs, taking into account the dependence upon chemical potential and Fermi energy. It is found that equilibrium concentrations of As interstitials will be much lower than equilibrium concentrations of As antisites in As-rich, $n$-type or semi-insulating GaAs.Comment: 10 pages, 5 figure

Coherent elastic neutrino-nucleus scattering: Terrestrial and astrophysical applications

Coherent elastic neutrino-nucleus scattering (CE$\nu$NS) is a process in which neutrinos scatter on a nucleus which acts as a single particle. Though the total cross section is large by neutrino standards, CE$\nu$NS has long proven difficult to detect, since the deposited energy into the nucleus is $\sim$ keV. In 2017, the COHERENT collaboration announced the detection of CE$\nu$NS using a stopped-pion source with CsI detectors, followed up the detection of CE$\nu$NS using an Ar target. The detection of CE$\nu$NS has spawned a flurry of activities in high-energy physics, inspiring new constraints on beyond the Standard Model (BSM) physics, and new experimental methods. The CE$\nu$NS process has important implications for not only high-energy physics, but also astrophysics, nuclear physics, and beyond. This whitepaper discusses the scientific importance of CE$\nu$NS, highlighting how present experiments such as COHERENT are informing theory, and also how future experiments will provide a wealth of information across the aforementioned fields of physics

Intersexuality and Trans-Identities within the Diversity Management Discourse

Within both the scientific discourse on workforce diversity, and diversity management practice, intersexuality and transgender issues have hitherto remained marginalized topics. This chapter gives an overview of the discourses on both phenomena, and proposes starting points for more inclusive organizational diversity management initiatives. It is shown that both topics represent different aspects of the category of "gender". The common practice of conceptually lumping together intersexuality, transgenderism, and sexual orientation can be seen as one important reason that intersexuality and transgenderism are rarely considered in organizational diversity management programs in terms of concrete action. Against this background, a modified, and more integrated approach to structuring the workforce alongside the different dimensions of diversity is proposed. It is shown that the categories of "biological sex and gender", "gender identity", and "sexual orientation" cannot be regarded as being separate from each other. They represent, rather, an interrelated organizational field of action that should be considered as being one interrelated topic for organizational diversity practices. This chapter derives this claim theoretically and discusses the consequences for organizational diversity management practices. For most organizations, this would mean a fundamental rethinking of their goals, in terms of workforce diversity, and the shaping of their diversity management programs
