The experience of a retreat for adolescent boys : A case study in an Australian Anglican school
Student retreats are not unfamiliar within education. Literature on retreat experiences acknowledges the important role that schools play in supporting social and character development, wellbeing, and the fostering of values. However, little is known of the extent to which the retreat aim and objectives are achieved. This case study qualitatively explored the effectiveness of the retreat experience through interviews with student retreatants and retreat teachers, together with the analysis of school documentation relevant to the retreat. Through a focus on documented purpose, planning and preparation, environmental considerations, program content, staffing; together with perceived value, and the depth of post-retreat follow-up and evaluation, the case study explored these criteria within the context of a Year 11 student retreat in an Australian Anglican school. The overall view of students and teachers recognised the influence of the retreat experience on students’ character-building, values, wellbeing, skill development, including social, and relationship skills, which they transferred back to school and into their personal life, and their overall outlook on life.
The discussion of findings enabled the generation of six themes integral to effectiveness. These included: Christian principles; values, morals, and ethics; character-building; wellbeing; retreat enablers; and retreat outcomes from which new understandings on the retreat phenomenon emerged.
Nine conclusions were drawn from the case study research. These contributed to new knowledge and underlined the retreat experience as an interdependent educational process central to the wider pastoral and character-building programs of the school. With this knowledge, it is anticipated that school leaders, both within the case study school, and more generally, will be better placed to assess what actions support the enhancement of the overall retreat effectiveness for student development within the mission, life, and culture of the school
An Advanced, Three-Dimensional Plotting Library for Astronomy
We present a new, three-dimensional (3D) plotting library with advanced
features, and support for standard and enhanced display devices. The library -
S2PLOT - is written in C and can be used by C, C++ and FORTRAN programs on
GNU/Linux and Apple/OSX systems. S2PLOT draws objects in a 3D (x,y,z) Cartesian
space and the user interactively controls how this space is rendered at run
time. With a PGPLOT inspired interface, S2PLOT provides astronomers with
elegant techniques for displaying and exploring 3D data sets directly from
their program code, and the potential to use stereoscopic and dome display
devices. The S2PLOT architecture supports dynamic geometry and can be used to
plot time-evolving data sets, such as might be produced by simulation codes. In
this paper, we introduce S2PLOT to the astronomical community, describe its
potential applications, and present some example uses of the library.Comment: 12 pages, 10 eps figures (higher resolution versions available from

Barriers to reporting non-motor symptoms to health-care providers in people with Parkinson's
Background: Non-motor symptoms (NMS) are common in Parkinson's disease (PD) and cause significant distress. A high rate of non-declaration of NMS by patients to healthcare providers (HCP) means that many NMS remain untreated. Current understanding of the factors preventing disclosure of NMS to HCPs is limited. The present study aimed to i) further assess the prevalence of NMS and associated distress, ii) establish current rates of NMS reporting across a range of sources, and iii) explore overall and any symptom specific barriers to help-seeking for NMS.
Methods: 358 PD patients completed a cross-sectional survey of NMS severity, reporting and barriers to help-seeking. A series of Generalised Estimating Equations were used to determine whether barriers were symptom specific.
Results: A mean of 10.5 NMS were reported by each patient. Rates of non-reporting of NMS ranged from 15 to 72% of those experiencing distressing symptoms. The most commonly reported barriers to help-seeking were acceptance of symptoms; lack of awareness that a symptom was associated with PD, and belief that no effective treatments were available. Symptom specific barriers were found for sexual dysfunction (embarrassment), unexplained pain and urinary problems (belief about lack of treatment availability).
Conclusion: A diverse range of barriers prevent PD patients reporting NMS to HCPs and these barriers differ between NMS. The study provides the foundations for developing interventions to increase reporting by targeting individual NMS. Increasing rates of help-seeking for NMS by patients to their Parkinson's healthcare providers will increase appropriate clinical care which may improve quality of life and well-being

Guided Poster Tour
Objective
1) To identify patient barriers to help-seeking for non-motor symptoms (NMS) from their Parkinson’s healthcare provider,
2) To determine whether barriers are symptom specific (e.g. embarrassment disclosing sexual problems) or patient specific (e.g. misattribution of a range of NMS to old age).
Background
NMS are common in Parkinson’s disease (PD) and cause significant distress and decreased quality of life. A high rate of non-declaration of NMS by patients to healthcare providers means that many NMS remain unrecognized and untreated, even in specialist clinical services. Current understanding of the factors preventing disclosure of NMS to healthcare professions is limited.
Method
358 PD patients completed the Non-motor Symptom Questionnaire and a barriers to help-seeking for NMS questionnaire developed from previous qualitative work. A Generalised Estimating Equation was used to determine whether barriers were symptom or individual specific.
Results
The sample had a mean age of 66.3 years, mean disease duration of 5.9 years and were 52.5% male. Urinary urgency was the most common NMS (65%) and sexual dysfunction was the symptom most frequently not disclosed (52%). Barriers to symptom disclosure varied dependent on symptom type. Pain and sleep problems were commonly not thought to be symptoms of PD. Bowel and bladder symptoms were often simply accepted as part of daily life and participants were unsure about the availability of effective treatments. Patients experienced embarrassment discussing sexual dysfunction.
Conclusion
Our results highlight the barriers which prevent PD patients reporting NMS to their Parkinson’s clinical team and the diversity of these barriers between different NMS. Strategies to improve rates of reporting must target individual NMS. For example, effective interventions might provide information regarding treatment efficacy for bowel and bladder symptoms or develop communication skills and normalising information for sexual dysfunction. The study provides the information needed to develop such individualised interventions. Increasing rates of disclosure of NMS by patients to their Parkinson’s healthcare providers will ensure patients receive appropriate clinical care which may increase quality of life and well-being
The fast transient sky with Gaia
The ESA Gaia satellite scans the whole sky with a temporal sampling ranging
from seconds and hours to months. Each time a source passes within the Gaia
field of view, it moves over 10 CCDs in 45 s and a lightcurve with 4.5 s
sampling (the crossing time per CCD) is registered. Given that the 4.5 s
sampling represents a virtually unexplored parameter space in optical time
domain astronomy, this data set potentially provides a unique opportunity to
open up the fast transient sky. We present a method to start mining the wealth
of information in the per CCD Gaia data. We perform extensive data filtering to
eliminate known on-board and data processing artefacts, and present a
statistical method to identify sources that show transient brightness
variations on ~2 hours timescales. We illustrate that by using the Gaia
photometric CCD measurements, we can detect transient brightness variations
down to an amplitude of 0.3 mag on timescales ranging from 15 seconds to
several hours. We search an area of ~23.5 square degrees on the sky, and find
four strong candidate fast transients. Two candidates are tentatively
classified as flares on M-dwarf stars, while one is probably a flare on a giant
star and one potentially a flare on a solar type star. These classifications
are based on archival data and the timescales involved. We argue that the
method presented here can be added to the existing Gaia Science Alerts
infrastructure for the near real-time public dissemination of fast transient
events.Comment: 10 pages, 5 figures and 5 tables; MNRAS in pres
RVS Spectra of Gaia Photometric Science Alerts
Gaia Photometric Science Alerts (GPSA) publishes Gaia G magnitudes and Blue Photometer (BP) and Red Photometer (RP) low-resolution epoch spectra of transient events. 27 high-resolution spectra from Gaia's Radial Velocity Spectrometer (RVS) of 12 GPSAs have also been published. These 27 RVS epoch spectra are presented next to their corresponding BP and RP epoch spectra in a single place for the first time. We also present one new RVS spectrum of a 13th GPSA that could not be published by the GPSA system. Of the 13 GPSA with RVS spectra, five are photometrically classified as unknown, five as supernovae (three as SN Ia, one as SN II, one as SN IIP), one as a cataclysmic variable, one as a binary microlensing event and one as a young stellar object. The five GPSAs classified as unknown are potential scientific opportunities, while all of them are a preview of the epoch RVS spectra that will be published in Gaia's fourth data release

Identifying barriers to help seeking for non-motor symptoms in people with Parkinson’s disease
Non-motor Symptoms (NMS) of Parkinson’s disease (PD) have a significant impact on quality of life. Despite this many NMS remain unreported by patients and consequently untreated. The present study explored barriers to help-seeking using two theoretical frameworks, the Common Sense Model of illness and Theoretical Domains Framework. 20 Participants completed semi-structured interviews to explore symptom beliefs and help-seeking behaviour. Uncertainty about the relationship of NMS to PD and lack of clarity around treatments were common. Embarrassment and communication difficulties were common for potentially sensitive symptoms such as sexual dysfunction. Symptom perceptions and beliefs about help-seeking acted as barriers to reporting NMS
Gaia transients in galactic nuclei
The high spatial resolution and precise astrometry and photometry of the Gaia
mission should make it particularly apt at discovering and resolving transients
occurring in, or near, the centres of galaxies. Indeed, some nuclear transients
are reported by the Gaia Science Alerts (GSA) team, but not a single confirmed
Tidal Disruption Event has been published. In order to explore the sensitivity
of GSA, we performed an independent and systematic search for nuclear
transients using Gaia observations. Our transient search is driven from an
input galaxy catalogue (derived from the Sloan Digital Sky Survey Release 12).
We present a candidate detection metric which is independent from the existing
GSA methodology, to see if Gaia Alerts are biased against the discovery of
nuclear transients, and in particular which steps may have an impact. Our
technique does require significant manual vetting of candidates, making
implementation in the GSA system impractical for daily operations, although it
could be run weekly, which for month-to-year long transients would make a
scientifically valuable addition. Our search yielded ~480 nuclear transients, 5
of which were alerted and published by GSA. The list of (in some cases ongoing)
transients includes candidates for events related to enhanced accretion onto a
super-massive black hole and TDEs. An implementation of the detection
methodology and criteria used in this paper as an extension of GSA could open
up the possibility for Gaia to fulfil the role as a main tool to find transient
nuclear activity as predicted in the literature.Comment: MNRAS accepted; full Table 2 attache

Evaluating Palin Stammering Therapy for School Children (Patin STSC 8-14): protocol for a feasibility randomised controlled trial comparing Patin STSC(8-14) with usual treatment
Background
Having a stammer can have a significant effect on a child’s social, emotional and educational development. With approximately 66,000 children in the UK having a stammer, there is a need to establish an adequate evidence base to inform clinical practice. We describe a feasibility trial to explore the effectiveness of a new therapy programme for children aged 8–14: Palin Stammering Therapy for School Children (Palin STSC(8–14)). Preliminary data from the Michael Palin Centre, where the programme was developed, indicate that Palin STSC(8–14) is effective in reducing stammering frequency and impact for children, with beneficial effects for parents too. We will investigate the feasibility of the methods required for a definitive randomised controlled trial to investigate the application of this therapy by NHS speech and language therapists (SLTs), compared with ‘treatment as usual’ (TAU), beyond the specialist context in which it was developed.
Methods
This is a two-arm feasibility cluster-randomised controlled trial of Palin STSC(8–14) with TAU control arm, and randomisation at the level of the SLT. Quantitative and qualitative data will be collected to examine the following: the recruitment and retention of therapists and families, the acceptability of the research processes and the therapeutic intervention and the appropriateness of the therapy outcome measures. Assessments will be completed by children and parents at baseline and 6 months later, including measures of stammering severity; the impact of child’s stammering on both children and parents; child temperament, behaviour and peer relations, anxiety; quality of life; and economic outcomes. There will also be a qualitative process evaluation, including interviews with parents, children, SLTs and SLT managers to explore the acceptability of both the research and therapy methods. Treatment fidelity will be examined through analysis of therapy session records and recordings.
Discussion
The findings of this feasibility trial will inform the decision as to whether to progress to a full-scale randomised controlled trial to explore the effectiveness of Palin STSC(8–14) when compared to Treatment as Usual in NHS SLT services. There is a strong need for an evidence-based intervention for school age children who stammer
Effect of postactivation potentiation on fifty-meter freestyle in national swimmers
Effect of postactivation potentiation (PAP) on fifty meters freestyle in national swimmers. 2013.- The purpose of this study was to examine the effect of PAP on 50m freestyle in national-level swimmers. Four warm-ups were compared: A traditional race-specific warm-up (RSWU), upper body PAP (UBPAP), lower body PAP (LBPAP) and combined PAP warm-up (CPAP). Eighteen (10 men, 8 women) national-level swimmers participated in this study, which included seven separate testing sessions. Participants' 3 repetition maximum (3RM) of the pull-up (PU) was established in session 1. In session 2, rest periods for muscle enhancement of the upper body were determined using a medicine-ballthrow test 4, 8 and 12 minutes post UBPAP stimulus (1 x 3RM of the PU). In session 3, swimmers performed a counter movement jump 4, 8 and 12 minutes post LBPAP stimulus (1x5 jumps to a box whilst carrying 10% of the participants' body weight). The 50m freestyle tests were performed on sessions 4 to 7, preceded by each warm-up protocol and corresponding rest periods. A repeated measures ANOVA (p<0.05) and Bonferroni post hoc test revealed that RSWU elicited faster swimming times than UBPAP (29.00 ± 2.05 vs. 29.36 ± 1.88s p=0.046). Additionally, when data were split into gender, in the male group the UBPAP elicited significantly slower times than RSWU (27.51 ± 1.06 vs. 28.01 ± 1.17s p=0.047) and CPAP (27.49 ± 1.12 vs. 28.01 ± 1.17s p=0.02). These findings suggest individualized PAP warm-up may be a valuable tool to enhance performance in sprint events, particularly in male swimmers. However, the PU may not be an appropriate PAP stimulus on its own
