Prospects for Stochastic Background Searches Using Virgo and LSC Interferometers

We consider the question of cross-correlation measurements using Virgo and the LSC Interferometers (LIGO Livingston, LIGO Hanford, and GEO600) to search for a stochastic gravitational-wave background. We find that inclusion of Virgo into the network will substantially improve the sensitivity to correlations above 200 Hz if all detectors are operating at their design sensitivity. This is illustrated using a simulated isotropic stochastic background signal, generated with an astrophysically-motivated spectrum, injected into 24 hours of simulated noise for the LIGO and Virgo interferometers.Comment: 11 pages, uses IOP style files, submitted to CQG for GWDAW11 proceedings; revised in response to referee comment

The use of complementary and alternative medicine by individuals with features of metabolic syndrome

OBJECTIVE: To compare the use of complementary and alternative medicine (CAM), including dietary supplements, by individuals with and without features of metabolic syndrome (FeMS). METHODS: Using a cross sectional study design, information was obtained by self-administered questionnaires from 300 university individuals. FeMS was defined as any individuals self-reporting at least one of the clinical diagnoses of diabetes, hypertension, hyperlipidemia, or obesity. Finally, two categories were created for cross tabulation, and individuals with and without FeMS were compared. RESULTS: Of the 192 individuals completing the study, 39% (n=76) were currently using or had used CAM therapies in the past 12 months. Individuals with FeMS (n=54, 28%) were more likely (P<0.05) to use different types of CAM therapies, in particular dietary and herbal supplements, aromatherapy and massage therapy compared to individuals without FeMS (n=138, 72%). CONCLUSION: Individuals with FeMS were more likely to use CAM, particularly supplements. Doctors need to properly inquire about and understand their patients' supplement use, especially if CAM therapies are used in conjunction with conventional medications

Assessing victim risk in cases of violent crime

Purpose: There is a body of evidence that suggests a range of psychosocial characteristics demarcate certain adults to be at an elevated risk for victimisation. To this end, the aim of the current study was to examine consistency between one police force, and a corresponding victim support service based in England, in their assessment of level of risk faced by victims of violent crime. Methodology: This study explored matched data on 869 adult victims of violent crime gathered from these two key services in Preston, namely Lancashire Constabulary and Victim Support, from which a sub-group of comparable ‘domestic violence’ cases (n=211) were selected for further examination. Findings: Data analyses revealed methodological inconsistencies in the assessment of victimisation resulting in discrepancies for recorded levels of risk in domestic violence cases across these two agencies. Practical implications: These findings provide a compelling argument for developing a more uniformed approach to victim assessment and indicate a significant training need. Value: This paper highlights areas of good practice and forwards several recommendations for improved practice that emphasises the integration of empirical research conducted by psychologists to boost the validity and reliability of risk assessment approaches and tools used

Repeat Victimisation, Retraumatisation and Victim Vulnerability

Abstract: This study explores the contribution that traumatic experiences and psychological post-traumatic stress symptoms make to predicting subsequent revictimisation in a sample of violent crime victims. In addition, the timing of first trauma exposure was also explored. Fifty-four adult victims (27 male and 27 female) of police recorded violent crime were interviewed and their traumatic exposure history, trauma symptomology, age at first trauma exposure as well as psychological and psychosocial functioning were assessed. These victims were followed longitudinally and subsequent revictimisation between six and twelve months post index victimisation measured. A greater number of types of trauma exposure was related lower emotional stability, higher trauma symptomology and revictimisation. Those victims with childhood traumatic exposure reported more trauma symptomology exposure than those without prior exposure. The implications for law enforcement and victim services are discussed

The experiences of ethnic minority MSM with NHS sexual health services in Britain

Objective: To compare the experiences of ethnic minority and white British men who have sex with men (MSM) who attend National Health Service (NHS) sexual health clinics in Britain. Methods: In 2007-2008 a national sample of MSM living in Britain was recruited through websites, in sexual health clinics, bars, clubs and other venues. Men completed an online survey which included questions about their experience of attending an NHS sexual health clinic. Results: Analysis is restricted to 363 ethnic minority MSM and 4776 white British MSM who had attended an NHS sexual health clinic in the 12 months before the survey. Compared with white British men, men from an Indian, Pakistani or Bangladeshi background were more likely to be very anxious about attending the clinic (adjusted odds ratio (aOR) 2.58, 95% confidence interval (CI) 1.63, 4.07), express concerns about being overheard at reception (aOR 1.68, 95% CI 1.10, 2.58), be uncomfortable in the waiting area (aOR 2.04, 95% CI 1.32, 3.15), or be afraid that people in their community would find out that they have sex with men (aOR 7.70, 95% CI 4.49,13.22). The adjusted odds ratios for being afraid that people in their community would find out that they have sex with men were also elevated for black Caribbean, black African, Chinese and other Asian men. Conclusion: Sexual health clinics should be aware that some ethnic minority MSM, particularly those from an Indian, Pakistani or Bangladeshi background, have heightened concerns about clinic attendance and confidentiality compared with white British MSM

Trauma characteristics and posttraumatic growth: The mediating role of avoidance coping, intrusive thoughts and social support

Objective: Previous research suggests trauma characteristics can impact on posttraumatic growth (PTG). The current study considers whether previously identified predictors of PTG may produce different outcomes dependent on the characteristics of the trauma experienced. Method: Active coping, avoidant coping, emotional coping, intrusive thoughts, social support and spirituality were examined as potential mediators of relationships between trauma characteristics (interpersonal trauma, number of trauma types and childhood trauma) and PTG. The responses of 268 adults exposed to multiple and wide-ranging stressors were used to generate three multiple mediation models. Results: Intrusive thoughts and social support exerted small but significant indirect effects in all three multiple mediation models. Avoidant coping mediated associations between the number of trauma types and PTG, and the relationship between childhood trauma to PTG. Conclusion: Relationships between trauma characteristics and PTG appear to be explained through the presence of avoidant coping strategies, intrusive thoughts and the individual’s social environment, which could be the focus of intervention efforts to promote positive change

Construct validity of the pictorial scale of perceived movement skill competence

Objectives: The Pictorial Scale of Perceived Movement Skill Competence (PMSC) assesses young children\u27s perceptions of movement skill competence: 12 perceived Fundamental Movement skills (FMS; based on the Test of Gross Motor Development 2nd edition TGMD-2) and six Active Play activities (e.g. cycling). The main study purpose was to assess whether children\u27s movement perception scores fit within the imposed constructs of Active Play and FMS by testing the latent structure and construct validity of the PMSC. Design: Construct validation study. Methods: Participants were part of the Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT). The latent structure of the PMSC responses was tested through confirmatory factor analysis (CFA) and Bayesian Structural Equation Modeling (BSEM). Internal consistency was conducted using polychoric correlation-based alphas. Results: The 303 children (boys 53.1%, n = 161) were aged 4-5 years (M = 4.7, SD = 0.46). The final model had an 18 item 3-factor solution with good fit indices (using CFA and BSEM). Factors were: Active Play (Bike, Board Paddle, Climb, Skate/Blade, Scooter, and Swim), Object Control - Hand Skills (Bounce, Catch, Hit, Throw), and FMS skills with a leg action (Gallop, Hop, Jump, Leap, Run, Step Slide, Kick, Roll). Alpha reliability values were: Active Play (0.78), Object Control-Hand Skills (0.76) and FMS-Dynamic Leg (0.84). Conclusion: Young children can distinguish between movement perceptions. The factors reflect the hypothesized structure in terms of FMS being distinguished from Active Play. Further research should investigate how and if these constructs change in children over time

Gleam: the GLAST Large Area Telescope Simulation Framework

This paper presents the simulation of the GLAST high energy gamma-ray telescope. The simulation package, written in C++, is based on the Geant4 toolkit, and it is integrated into a general framework used to process events. A detailed simulation of the electronic signals inside Silicon detectors has been provided and it is used for the particle tracking, which is handled by a dedicated software. A unique repository for the geometrical description of the detector has been realized using the XML language and a C++ library to access this information has been designed and implemented.Comment: 10 pages, Late

Using coloured filters to reduce the symptoms of visual stress in children with reading delay

Background: Meares Irlen Syndrome (MIS), otherwise known as “visual stress”, is one condition that can cause difficulties with reading. Aim: This study aimed to compare the effect of two coloured-filter systems on the symptoms of visual stress in children with reading delay. Methods: The study design was a pre-test, post-test, randomized head-to-head comparison of two filter systems on the symptoms of visual stress in school children. A total of 68 UK mainstream schoolchildren with significant impairment in reading ability completed the study. Results: The filter systems appeared to have a large effect on the reported symptoms between pre and post three-month time points (d = 2.5, r = 0.78). Both filter types appeared to have large effects (Harris d = 1.79, r = 0.69 and DRT d = 3.22, r = 0.85). Importantly, 35% of participants’ reported that their symptoms had resolved completely; 72% of the 68 children appeared to gain improvements in three or more visual stress symptoms. Conclusion and significance: The reduction in symptoms, which appeared to be brought about by the use of coloured filters, eased the visual discomfort experienced by these children when reading. This type of intervention therefore has the potential to facilitate occupational engagement
