Parent cardiac response in the context of their child’s completion of the cold pressor task: A pilot study
Parents’ ability to regulate their emotions is essential to providing supportive caregiving behaviours when their child is in pain. Extant research focuses on parent self-reported experience or observable behavioural responses. Physiological responding, such as heart rate (HR) and heart rate variability (HRV), is critical to the experience and regulation of emotions and provides a complementary perspective on parent experience; yet, it is scarcely assessed. This pilot study examined parent (n = 25) cardiac response (HR, HRV) at rest (neutral film clip), immediately before the cold pressor task (pre-CPT), and following the CPT (post-CPT). Further, variables that may influence changes in HR and HRV in the context of pediatric pain were investigated, including (1) initial HRV, and (2) parent perception of their child’s typical response to needle procedures. Time-domain (root mean square of successive differences; RMSSD) and frequency-domain (high-frequency heart rate variability; HF-HRV) parameters of HRV were computed. HR and HF-HRV varied as a function of time block. Typical negative responses to needle pain related to higher parental HR and lower HRV at rest. Parents with higher HRV at baseline experienced the greatest decreases in HRV after the CPT. Consequently, considering previous experience with pain and resting HRV levels are relevant to understanding parent physiological responses before and after child pain
Family, Partner and Carer Intervention Manual for Personality Disorders
Families, partners and carers of persons with personality disorder experience significant distress and burden within this role (Bailey & Grenyer, 2013, 2014; Day, Bourke, Townsend, & Grenyer, 2018). Treatment guidelines now recommend supporting families and carers, including involving them in the treatment process to improve wellbeing and thereby assist them in effectively caregiving for the person with personality disorder. This manual has been designed to help services engage and work with families and carers of persons with personality disorder in a brief four session intervention that aims to provide information, support and strategies. This manual has been developed in accordance with the relational model advocated by the Project Air Strategy for Personality Disorders (see The Relational Model of Treatment in the Project Air Strategy Treatment Guidelines). The relational model involves an integrative and collaborative approach to personality disorders treatment, focussing not only on the person with personality disorder but also carers, health services and clinicians. In the relational treatment model, the person’s problems are seen as stemming from problematic and dysfunctional relationship patterns that have developed over time (Grenyer, 2012). These relationship patterns are considered both intrapersonal (how the person relates to themselves, including their feelings and thoughts) and interpersonal (how they relate to others). The relational model recognises that responsibility for effective relationships also rests with others involved in the person’s life. It is now recognised that a service system that works together in an integrated manner better supports people with personality disorders, rather than any sector working in isolation (Grenyer, 2014; Grenyer, Lewis, Fanaian, & Kotze, 2018). Therefore, clinicians, case managers, carers, youth workers, teachers, school counsellors and the broader community share a joint responsibility to respond effectively to the person in a way that is helpful and encouraging (Townsend, Gray, Lancaster, & Grenyer, 2018). Indeed, longitudinal research indicates that clinicians attitudes towards working with individuals with a personality disorder has improved, reflecting the hope and optimism of treatment providers and the wider community informed by over 27 years of evidence and treatment (Day, Hunt, Cortis-Jones, & Grenyer, 2018). Caring for and helping people with personality disorders is everyone\u27s business (Grenyer, Ng, Townsend, & Rao, 2017) and everyone can choose to adopt the key principles from the Project Air Strategy model. This manual was utilized in a randomized controlled trial that sought to provide education and support to carers of individuals with a personality disorder (Grenyer et al., 2018). Compared to waitlist control groups, participants reported improvements in their relationship with their relative with a personality disorder and improvements in family empowerment (reflecting carers ability to take an active role in supporting their relatives treatment). At a 12 month follow-up these improvements were maintained and carers also reported an improvement in their mental health and decreased levels of burden.https://ro.uow.edu.au/uowbooks/1025/thumbnail.jp
Improving the LSST dithering pattern and cadence for dark energy studies
The Large Synoptic Survey Telescope (LSST) will explore the entire southern
sky over 10 years starting in 2022 with unprecedented depth and time sampling
in six filters, . Artificial power on the scale of the 3.5 deg LSST
field-of-view will contaminate measurements of baryonic acoustic oscillations
(BAO), which fall at the same angular scale at redshift . Using the
HEALPix framework, we demonstrate the impact of an "un-dithered" survey, in
which of each LSST field-of-view is overlapped by neighboring
observations, generating a honeycomb pattern of strongly varying survey depth
and significant artificial power on BAO angular scales. We find that adopting
large dithers (i.e., telescope pointing offsets) of amplitude close to the LSST
field-of-view radius reduces artificial structure in the galaxy distribution by
a factor of 10. We propose an observing strategy utilizing large dithers
within the main survey and minimal dithers for the LSST Deep Drilling Fields.
We show that applying various magnitude cutoffs can further increase survey
uniformity. We find that a magnitude cut of removes significant
spurious power from the angular power spectrum with a minimal reduction in the
total number of observed galaxies over the ten-year LSST run. We also determine
the effectiveness of the observing strategy for Type Ia SNe and predict that
the main survey will contribute 100,000 Type Ia SNe. We propose a
concentrated survey where LSST observes one-third of its main survey area each
year, increasing the number of main survey Type Ia SNe by a factor of
1.5, while still enabling the successful pursuit of other science
drivers.Comment: 9 pages, 6 figures, published in SPIE proceedings; corrected typo in

A Randomized Controlled Trial of Group Psychoeducation for Carers of Persons With Borderline Personality Disorder
Carers of persons with borderline personality disorder (BPD) experience high burden. Treatment guidelines advocate involving carers in comprehensive therapy approaches. This study is a randomized controlled trial of group psychoeducation, compared to waitlist. Group psychoeducation involved 6-8 carers per group and focused on improving relationship patterns between carers and relatives with BPD, psychoeducation about the disorder, peer support and self-care, and skills to reduce burden. Carers were randomized into intervention (N = 33) or waitlist (N = 35). After 10 weeks, those in the intervention reported improvements in dyadic adjustment with their relative, greater family empowerment, and reduced expressed emotion, sustained after 12 months. There were also improvements in carers\u27 perceptions of being able to play a more active role, such as interacting with service providers. This study demonstrates that providing structured group programs for carers can be an effective way of extending interventions to a group experiencing high burden
A team approach to recruitment in hospice research:engaging patients, close persons and health professionals
Research is vital to the future development of hospice care. However, research in hospice settings is very challenging. This paper describes a case study of a successful multidisciplinary research team approach (MDRT) to the recruitment of participants (hospice patients, family members and health professionals) for a study in a hospice setting on the economic evaluation of end-of-life care. A successful recruitment plan includes three key strategies: identifying key members of the MDRT early in the research process; having a clear and constant communication stream; and creating an environment where all team members have a shared commitment to the research, all voices are heard and valued, and everyone contributes to the research aims. An MDRT approach will be helpful to guide the development of successful recruitment plans for academic-community research partnerships in the hospice setting
Brief intervention manual for personality disorders

It is particularly focused on clients in crisis, who have complex needs, by providing practical therapeutic techniques in the prevention and treatment of high-risk challenging behaviours. It describes a four session brief intervention that can act as the first step in a treatment journey for people with this disorder
Social Facilitation in Fear Appeals Creates Positive Affect but Inhibits Healthy Eating Intentions
The social facilitation of eating plays a significant role in influencing individuals’ eating decisions. However, how social eating cues are processed in health promotion messages is unclear. This study examined individuals’ food craving in response to social cues in images (Experiment 1) and emotional experiences, perceived threat, perceived efficacy, behavioral intentions, and motivational coactivation elicited by social eating cues in obesity prevention fear appeals (Experiment 2). Results suggested that the presence of a group of people eating in an image facilitated food craving for the presented foods. Moreover, fear appeals that presented obesity and its consequences with more social eating cues, versus individual eating cues, generated greater positive emotional responses, perceived threat severity, response and self-efficacy, and motivational coactivation indicating more attention and threat vigilance. However, these cues also generated fewer self-reported intentions to change unhealthy eating behaviors. Implications and suggestions for future research are discussed
Reducing prolonged sedentary time using a treadmill desk acutely improves cardiometabolic risk markers in male and female adults
The objectives of this study were to evaluate the acute effects of interrupting prolonged sitting with an accumulated 2 h of light-intensity walking on postprandial cardiometabolic risk markers. In this randomised crossover trial, 24 participants (twelve males) aged 18-55 years took part in two, 6.5 h conditions: 1) prolonged sitting (SIT) and 2) sitting interrupted hourly with 20 min light-intensity treadmill desk walking at between 1.2-3.5 km/h-1 (INT-SIT). Standardized meals were provided at 0 h and 3 h. Blood samples and blood pressure measures were taken hourly. Statistical analyses were completed using linear mixed models. Postprandial incremental area under the curve responses (mmol/L∙6.5 h) for glucose (4.52 [3.47, 5.56] and 6.66 [5.62, 7.71] for INT-SIT and SIT, respectively) and triglycerides (1.96 [0.96, 2.96] and 2.71 [1.70, 3.71] mmol/L∙6.5 h, for INT-SIT and SIT, respectively) were significantly lower in INT-SIT than SIT. Mean systolic and diastolic blood pressure responses were lower by 3% and 4%, respectively, in INT-SIT than SIT (P0.05). These findings suggest that interrupting sitting with an accumulated 2 h of light-intensity walking acutely improves cardiometabolic risk levels in males and females compared with prolonged sitting
Modelling geomagnetically induced currents in midlatitude Central Europe using a thin-sheet approach
Geomagnetically induced currents (GICs) in power systems, which can lead to transformer damage over the short and the long term, are a result of space weather events and geomagnetic variations. For a long time, only high-latitude areas were considered to be at risk from these currents, but recent studies show that considerable GICs also appear in midlatitude and equatorial countries. In this paper, we present initial results from a GIC model using a thin-sheet approach with detailed surface and subsurface conductivity models to compute the induced geoelectric field. The results are compared to measurements of direct currents in a transformer neutral and show very good agreement for short-period variations such as geomagnetic storms. Long-period signals such as quiet-day diurnal variations are not represented accurately, and we examine the cause of this misfit. The modelling of GICs from regionally varying geoelectric fields is discussed and shown to be an important factor contributing to overall model accuracy. We demonstrate that the Austrian power grid is susceptible to large GICs in the range of tens of amperes, particularly from strong geomagnetic variations in the east–west direction
