Use of the Strengths & Difficulties Questionnaire to identify treatment needs in looked after children referred to CAMHS
© The Author(s) 2019Background: In England and Wales, the Strengths & Difficulties Questionnaire (SDQ) is used to assess and monitor looked after childrenâs (LAC) mental health; and some targeted CAMHS teams use it to decide who can access services. However, the ability of the single-informant SDQ to identify LAC who need mental health treatment is insufficiently understood. Methods: 144 LAC referrals to a Targeted CAMHS Team were screened as part of a larger study. To establish how well the SDQ identified children who required treatment, Total Difficulties Scores (TDS) from single-informant SDQs submitted at referral were compared to treatment recommendations following routine CAMHS assessment in a real-world setting. To explain the results, clinicians (n=9) from the team were interviewed and key themes identified using Thematic Analysis. Results: Optimal accuracy calculations for SDQs completed by carers (TDS=17, sensitivity .67, specificity .57), teachers (TDS=17, sensitivity .79, specificity .71) and young people (TDS=14, sensitivity.79, specificity .42) compared to the outcome of routine CAMHS assessments indicated that the number of children whose treatment needs were not identified by their SDQ score may be unacceptably high. Key themes from clinician interviews identified possible gaps and limitations: Developmental Trauma and Attachment Difficulties, A different kind of âpatient?â, Seeing the bad but neglecting the sad, and The importance of clinical judgement. Conclusions: Contrary to UK Government policy, this study suggests that the single-report SDQ should not be relied upon as a sole means of identifying mental health difficulties in this vulnerable, high-risk population.Peer reviewedFinal Accepted Versio

Parallel hippocampal-parietal circuits for self- and goal-oriented processing
The hippocampus is critically important for a diverse range of cognitive processes, such as episodic memory, prospective memory, affective processing, and spatial navigation. Using individual-specific precision functional mapping of resting-state functional MRI data, we found the anterior hippocampus (head and body) to be preferentially functionally connected to the default mode network (DMN), as expected. The hippocampal tail, however, was strongly preferentially functionally connected to the parietal memory network (PMN), which supports goal-oriented cognition and stimulus recognition. This anterior-posterior dichotomy of resting-state functional connectivity was well-matched by differences in task deactivations and anatomical segmentations of the hippocampus. Task deactivations were localized to the hippocampal head and body (DMN), relatively sparing the tail (PMN). The functional dichotomization of the hippocampus into anterior DMN-connected and posterior PMN-connected parcels suggests parallel but distinct circuits between the hippocampus and medial parietal cortex for self- versus goal-oriented processing
Astrometric accelerations as dynamical beacons : discovery and characterization of HIP 21152 B, the First T-dwarf companion in the Hyades * * Based in part on data collected at Subaru Telescope, which is operated by the National Astronomical Observatory of Japan.
Benchmark brown dwarf companions with well-determined ages and model-independent masses are powerful tools to test substellar evolutionary models and probe the formation of giant planets and brown dwarfs. Here, we report the independent discovery of HIP 21152 B, the first imaged brown dwarf companion in the Hyades, and conduct a comprehensive orbital and atmospheric characterization of the system. HIP 21152 was targeted in an ongoing high-contrast imaging campaign of stars exhibiting proper-motion changes between Hipparcos and Gaia, and was also recently identified by Bonavita et al. (2022) and Kuzuhara et al. (2022). Our Keck/NIRC2 and SCExAO/CHARIS imaging of HIP 21152 revealed a comoving companion at a separation of 0.âł37 (16 au). We perform a joint orbit fit of all available relative astrometry and radial velocities together with the Hipparcos-Gaia proper motions, yielding a dynamical mass of 24â4+6MJup , which is 1â2Ï lower than evolutionary model predictions. Hybrid grids that include the evolution of cloud properties best reproduce the dynamical mass. We also identify a comoving wide-separation (1837âł or 7.9 Ă 104 au) early-L dwarf with an inferred mass near the hydrogen-burning limit. Finally, we analyze the spectra and photometry of HIP 21152 B using the Saumon & Marley (2008) atmospheric models and a suite of retrievals. The best-fit grid-based models have f sed = 2, indicating the presence of clouds, T eff = 1400 K, and logg=4.5dex . These results are consistent with the objectâs spectral type of T0 ± 1. As the first benchmark brown dwarf companion in the Hyades, HIP 21152 B joins the small but growing number of substellar companions with well-determined ages and dynamical masses

Quantitative estimates of glacial refugia for chimpanzees (Pan troglodytes) since the Last Interglacial (120,000 BP).
Paleoclimate reconstructions have enhanced our understanding of how past climates have shaped present-day biodiversity. We hypothesize that the geographic extent of Pleistocene forest refugia and suitable habitat fluctuated significantly in time during the late Quaternary for chimpanzees (Pan troglodytes). Using bioclimatic variables representing monthly temperature and precipitation estimates, past human population density data, and an extensive database of georeferenced presence points, we built a model of changing habitat suitability for chimpanzees at fine spatio-temporal scales dating back to the Last Interglacial (120,000 BP). Our models cover a spatial resolution of 0.0467° (approximately 5.19âkm2 grid cells) and a temporal resolution of between 1000 and 4000 years. Using our model, we mapped habitat stability over time using three approaches, comparing our modeled stability estimates to existing knowledge of Afrotropical refugia, as well as contemporary patterns of major keystone tropical food resources used by chimpanzees, figs (Moraceae), and palms (Arecacae). Results show habitat stability congruent with known glacial refugia across Africa, suggesting their extents may have been underestimated for chimpanzees, with potentially up to approximately 60,000âkm2 of previously unrecognized glacial refugia. The refugia we highlight coincide with higher species richness for figs and palms. Our results provide spatio-temporally explicit insights into the role of refugia across the chimpanzee range, forming the empirical foundation for developing and testing hypotheses about behavioral, ecological, and genetic diversity with additional data. This methodology can be applied to other species and geographic areas when sufficient data are available
Sexual torture. Exploring discourses within one refugee community
There is a lack of psychological research concerning how refugee communities in the U.K.
make sense of sexual torture perpetrated in their country of origin. In particular, current
psychological conceptualisations of emotional distress related to sexual torture betray
Western culture's preference for individualising such distress and separating the individual
from their community. Discourses are thought to constrain or encourage particular ways of
talking and acting and therefore may determine the relationship between survivors of sexual
torture and their community. Discourses offer a link between the individual and their
community and allow some explorations of cultural and political context which are non
Western. Interviews were conducted through an interpreter with 9 members of a Congolese
refugee community organisation to explore the discourses they were drawing upon in relation
to sexual torture. Foucauldian Discourse Analysis was utilised to identify discourses such as
sexual worth, ancestral power, forgetting, God as ultimate power, lawlessness and systematic
rape. The implications of these discourses for the relationship between the community and
survivors of sexual torture were explored, as where the implications for psychologists in their
work with both survivors and refugee communities
Ethnic identity and wellbeing in the lives of third-generation British Bangladeshi adults: Finding a âsense of belongingâ
© 2022 The Author(s). This is an open access article distributed under the terms of the Creative Commons Attribution License (CC BY), https://creativecommons.org/licenses/by/4.0/This study investigated third generation Bangladeshi adultsâ experiences of ethnic identity (EI) and sense of wellbeing. British citizens from racially minoritised backgrounds, such as British Bangladeshis, face numerous challenges related to cultural adjustment, discrimination, and exclusion that can impact wellbeing. Strong EI has been shown to increase psychological wellbeing in minority ethnic populations. Fifteen participants who identified as third-generation British Bangladeshi adults were engaged in semi-structured interviews to explore their experiences of EI and wellbeing. Thematic analysis of the data conceptualised three main themes, namely, âOh my God, Iâm differentâ: Being made to feel like an outsider in Britain; âYouâre a coconutâ: Being made to feel like an outsider within the British Bangladeshi community; and âA proper sense of belongingâ through ethnic identity. The findings point towards the role that EI can play in later generation immigrantsâ sense of self and wellbeing. Implications are discussed.Peer reviewe
