Differences between staff groups in perception of risk assessment and risk management of inappropriate sexual behaviour in patients with traumatic brain injury
This research explored staff perceptions of risk assessment and management of inappropriate sexual behaviour (ISB) displayed in patients following a Traumatic Brain Injury (TBI). The primary focus was to determine differences in perceptions between qualified (N=40) and direct care staff (N=47). Vignettes depicting ISB displayed by a male following a TBI were rated. The vignettes varied in behaviour (intimate versus non-contact) and age of the victim (child versus adult). Ratings for causal explanations (poor management, attention seeking, negative emotion and education), attributions (need for action and increase awareness) and emotions were analysed alongside risk assessment and management variables. Intimate contact ISB and ISB directed towards a child were perceived to be more serious and in need of intervention. Direct care staff perceived ISB to be due to sexual motivations, poor emotion control and to seek attention. They elicited greater negative emotions and based their judgements of risk on seriousness. On the other hand, qualified staff were more concerned about implementing interventions based on the risk of recurrence. Differences between staff groups could cause conflict regarding the assessment and management of ISB in TBI. Training to increase awareness of the behaviour could minimise differences and produce greater cohesion within clinical practice
Profiles of Dark Matter Velocity Anisotropy in Simulated Clusters
We report statistical results for dark matter (DM) velocity anisotropy,
\beta, from a sample of some 6000 cluster-size halos (at redshift zero)
identified in a \Lambda CDM hydrodynamical adaptive mesh refinement simulation
performed with the Enzo code. These include profiles of \beta\ in clusters with
different masses, relaxation states, and at several redshifts, modeled both as
spherical and triaxial DM configurations. Specifically, although we find a
large scatter in the DM velocity anisotropy profiles of different halos (across
elliptical shells extending to at least ~), universal patterns are
found when these are averaged over halo mass, redshift, and relaxation stage.
These are characterized by a very small velocity anisotropy at the halo center,
increasing outward to about 0.27 and leveling off at about .
Indirect measurements of the DM velocity anisotropy fall on the upper end of
the theoretically expected range. Though measured indirectly, the estimations
are derived by using two different surrogate measurements - X-ray and galaxy
dynamics. Current estimates of the DM velocity anisotropy are based on very
small cluster sample. Increasing this sample will allow testing theoretical
predictions, including the speculation that the decay of DM particles results
in a large velocity boost. We also find, in accord with previous works, that
halos are triaxial and likely to be more prolate when unrelaxed, whereas
relaxed halos are more likely to be oblate. Our analysis does not indicate that
there is significant correlation (found in some previous studies) between the
radial density slope, \gamma, and \beta\ at large radii, .Comment: 12 pages, 17 figures, accepted to Ap
Should We Learn Probabilistic Models for Model Checking? A New Approach and An Empirical Study
Many automated system analysis techniques (e.g., model checking, model-based
testing) rely on first obtaining a model of the system under analysis. System
modeling is often done manually, which is often considered as a hindrance to
adopt model-based system analysis and development techniques. To overcome this
problem, researchers have proposed to automatically "learn" models based on
sample system executions and shown that the learned models can be useful
sometimes. There are however many questions to be answered. For instance, how
much shall we generalize from the observed samples and how fast would learning
converge? Or, would the analysis result based on the learned model be more
accurate than the estimation we could have obtained by sampling many system
executions within the same amount of time? In this work, we investigate
existing algorithms for learning probabilistic models for model checking,
propose an evolution-based approach for better controlling the degree of
generalization and conduct an empirical study in order to answer the questions.
One of our findings is that the effectiveness of learning may sometimes be
limited.Comment: 15 pages, plus 2 reference pages, accepted by FASE 2017 in ETAP

Sub-mm detection of a high redshift Type 2 QSO
We report on the first SCUBA detection of a Type 2 QSO at z=3.660 in the
Chandra Deep Field South. This source is X-ray absorbed, shows only narrow
emission lines in the optical spectrum and is detected in the sub-mm: it is the
ideal candidate in an evolution scheme for AGN (e.g. Fabian (1999); Page et al.
(2004)) of an early phase corresponding to the main growth of the host galaxy
and formation of the central black hole. The overall photometry (from the radio
to the X-ray energy band) of this source is well reproduced by the spectral
energy distribution (SED) of NGC 6240, while it is incompatible with the
spectrum of a Type 1 QSO (3C273) or a starburst galaxy (Arp 220). Its sub-mm
(850 \mu m) to X-ray (2 keV) spectral slope (alpha_SX) is close to the
predicted value for a Compton-thick AGN in which only 1% of the nuclear
emission emerges through scattering. Using the observed flux at 850 \mu m we
have derived a SFR=550--680 M_dust=4.2 10^8 M_odotComment: 6 Pages, 5 Figures, accepted for publication in MNRA
Hilbert Lattice Equations
There are five known classes of lattice equations that hold in every infinite
dimensional Hilbert space underlying quantum systems: generalised
orthoarguesian, Mayet's E_A, Godowski, Mayet-Godowski, and Mayet's E equations.
We obtain a result which opens a possibility that the first two classes
coincide. We devise new algorithms to generate Mayet-Godowski equations that
allow us to prove that the fourth class properly includes the third. An open
problem related to the last class is answered. Finally, we show some new
results on the Godowski lattices characterising the third class of equations.Comment: 24 pages, 3 figure
Shuttle walk tests in people with COPD who demonstrate exercise-induced oxygen desaturation: An analysis of test repeatability and cardiorespiratory responses
Š 2017, Š The Author(s) 2017. Exercise-induced oxygen desaturation (EID) is prevalent in people with chronic obstructive pulmonary disease (COPD). This article reports a sub-analysis from a randomized controlled trial (RCT) in people with COPD and EID (COPD/EID). The primary aim, in people with COPD/ EID, was to determine the repeatability of the distance and time walked in the incremental shuttle walk test (ISWT) and endurance shuttle walk test (ESWT), respectively. A secondary aim was to determine whether any participant characteristics predicted those who did not demonstrate improvements on a repeat ISWT or ESWT. Participants with nadir oxygen saturation (SpO2) < 90% on the 6-minute walk test were recruited to the RCT. Two ISWTs and two ESWTs were then performed as part of the baseline assessments, and participants were included in this sub-analysis if their nadir SpO2was <90% during the better of two ISWTs. Repeatability of the tests was analysed using BlandâAltman plots and paired t-tests. Participant characteristics of age, lung function, level of nadir SpO2and end-test dyspnoea were used to predict those who were not likely to demonstrate improvements on a repeat test using receiver operating curves. Eighty-seven participants (mean age (standard deviation, SD) 70 (7) years; forced expiratory volume in one second (FEV1) 47 (17)% predicted) were included. The mean differences (coefficient of repeatability) for the ISWTs and ESWTs were 9 m (55 m) and 19 seconds (142 seconds) respectively (p < 0.05). No participant characteristic predicted the absence of improvement on the second ISWT (area under the curve (AUC) ranged from 0.49 to 0.58, all p > 0.2) or the second ESWT (AUC ranged from 0.43 to 0.52, all p > 0.3). Although repeating the tests showed only small improvements in distance (ISWT) and time (ESWT) walked in people with COPD/EID, the variability was large making definite conclusions about test repeatability in these individuals difficult
