The Many Faces of Risk: A Qualitative Study of Risk in Outpatient Involuntary Treatment.
Objective: This study aimed to derive a conceptualisation of risk in outpatient involuntary psychiatric treatment that has utility and meaning for stakeholders. Methods: Thirty-eight participants âpatients, caregivers, clinicians and legal decision makers â participated in qualitative interviews about their experiences of outpatient involuntary psychiatric treatment. Interview data was analysed using a general inductive method. Results: Six types of risk were identified: âactual harmâ, âsocial adversityâ, âtherapeutic outcome/compromised treatmentâ, âthe systemâ, âinterpersonal distressâ, and âepistemicâ. There were overlaps between the discourses on risk, but variation in how different aspects of risk were emphasised. Conclusions: Based on the findings, a comprehensive model of âriskâ contextualized to outpatient involuntary treatment is proposed. It incorporates the domains of ârisk of harm to self or othersâ; ârisk of social adversityâ; ârisk of excess distressâ; and, ârisk of compromised treatmentâ. This model may have instrumental value in the implementation and the scrutiny of risk-based mental health laws.funded by a discretionary grant from the Mental Health, Drug and Alcohol Office of NSW Healt
The lived experience of involuntary community treatment: a qualitative study of mental health consumers and carers
Objective: To describe the lived experiences of people subject to community treatment orders (CTOs) and their carers. Method: We recruited 11 participants (five mental health consumers and six carers) through consumer and carer networks in NSW, Australia, to take part in interviews about their experiences. We analysed the interview data set using established qualitative methodologies. Results: The lived experiences were characterised by âaccessâ concerns, âisolationâ, âloss and traumaâ, âresistance and resignationâ and âvulnerability and distressâ. The extent and impact of these experiences related to the severity of mental illness, the support available for people with mental illnesses and their carers, the social compromises associated with living with mental illness, and the challenges of managing the relationships necessitated by these processes. Conclusions: The lived experience of CTOs is complex: it is one of distress and profound ambivalence. The distress is an intrinsic aspect of the experience of severe mental illness, but it also emerges from communication gaps, difficulty obtaining optimal care and accessing mental health services. The ambivalence arises from an acknowledgement that while CTOs are coercive and constrain autonomy, they may also be beneficial. These findings can inform improvements to the implementation of CTOs and the consequent experiences.

Experimental study of pedestrian flow through a bottleneck
In this work the results of a bottleneck experiment with pedestrians are
presented in the form of total times, fluxes, specific fluxes, and time gaps. A
main aim was to find the dependence of these values from the bottleneck width.
The results show a linear decline of the specific flux with increasing width as
long as only one person at a time can pass, and a constant value for larger
bottleneck widths. Differences between small (one person at a time) and wide
bottlenecks (two persons at a time) were also found in the distribution of time
gaps.Comment: accepted for publication in J. Stat. Mec
The Landscape Archaeology of Knettishall Heath, Suffolk and its Implications
This paper briefly describes the results of archaeological fieldwork carried out in an area of heathland, currently managed as a nature reserve, in East Anglia. Although the earthworks recorded are for the most part unremarkable, they demonstrate the variety and intensity of human exploitation which shaped this âtraditionally managedâ habitat. They also serve to emphasise the extent to which modern conservation management can radically change the long-term character of individual places
Pedestrian, Crowd, and Evacuation Dynamics
This contribution describes efforts to model the behavior of individual
pedestrians and their interactions in crowds, which generate certain kinds of
self-organized patterns of motion. Moreover, this article focusses on the
dynamics of crowds in panic or evacuation situations, methods to optimize
building designs for egress, and factors potentially causing the breakdown of
orderly motion.Comment: This is a review paper. For related work see http://www.soms.ethz.c
Performance and calibration of quark/gluon-jet taggers using 140 fbâ1 of pp collisions at âs = 13 TeV with the ATLAS detector
The identification of jets originating from quarks and gluons, often referred to as quark/gluon tagging, plays an important role in various analyses performed at the Large Hadron Collider, as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced background. This paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration, using âs = 13 TeV protonâproton collision data with an integrated luminosity of 140 fb collected by the ATLAS experiment. Two taggers with high performances in rejecting jets from gluon over jets from quarks are studied: one tagger is based on requirements on the number of inner-detector tracks associated with the jet, and the other combines several jet substructure observables using a boosted decision tree. A method is established to determine the quark/gluon fraction in data, by using quark/gluon-enriched subsamples defined by the jet pseudorapidity. Differences in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points
Probing the CP nature of the topâHiggs Yukawa coupling in ttÂŻH and tH events with H â bbÂŻ decays using the ATLAS detector at the LHC
The CP properties of the coupling between the Higgs boson and the top quark are investigated using 139 fbâ1 of protonâproton collision data recorded by the ATLAS experiment at the LHC at a centre-of-mass energy of âs = 13 TeV. The CP structure of the top quarkâHiggs boson Yukawa coupling is probed in events with a Higgs boson decaying into a pair of b-quarks and produced in association with either a pair of top quarks, ttH , or a single top quark, tH. Events containing one or two electrons or muons are used for the measurement. Multivariate techniques are used to select regions enriched in ttH and tH events, where dedicated CP -sensitive observables are exploited. In an extension of the Standard Model (SM) with a CP -odd admixture in the topâHiggs Yukawa coupling, the mixing angle between CP -even and CP -odd couplings is measured to be α = 11 °+52° â73°, compatible with the SM prediction corresponding to α = 0
Search for boosted diphoton resonances in the 10 to 70 GeV mass range using 138 fbâ1 of 13 TeV pp collisions with the ATLAS detector
A search for diphoton resonances in the mass range between 10 and 70 GeV with the ATLAS experiment at the Large Hadron Collider (LHC) is presented. The analysis is based on pp collision data corresponding to an integrated luminosity of 138 fbâ1 at a centre-of-mass energy of 13 TeV recorded from 2015 to 2018. Previous searches for diphoton resonances at the LHC have explored masses down to 65 GeV, finding no evidence of new particles. This search exploits the particular kinematics of events with pairs of closely spaced photons reconstructed in the detector, allowing examination of invariant masses down to 10 GeV. The presented strategy covers a region previously unexplored at hadron colliders because of the experimental challenges of recording low-energy photons and estimating the backgrounds. No significant excess is observed and the reported limits provide the strongest bound on promptly decaying axion-like particles coupling to gluons and photons for masses between 10 and 70 GeV
