Farmers tell us how to help improve their mental health help-seeking

Farmers’ mental health help-seeking is reported to be poor. Mental health help-seeking is seeking help from professionals such as GPs and psychologists for issues relating to distress or mental health (Rickwood & Thomas, 2012). Timely mental health help-seeking behaviour is important because it may minimise any negative outcomes. At present, there is no research that has identified how to target farmers to improve their mental health help-seeking. It is known that tailored approaches to intervention are superior and this is likely to be so for intervening with farmers whom have a strong culture and a vastly different situation than metropolitan populations. This study is part of a body of work exploring the factors that influence mental health help-seeking in farmers. Semi-structured interviews were conducted with 10 farmers (farming as their occupation) as well as 10 farmers’ partners (for their additional insight), all of whom resided/worked in Queensland. Braun and Clarke’s (2006) technique of thematic analysis was used to analyse the data. Based on the data three themes were developed regarding intervention: education (what needs to be taught and how to teach it), the medium (which mediums preferred and engagement with them) and multi-faceted programs (Many aspects important such as community input and role of GPs, family, and friends). This research improves the knowledge on how to target interventions, including the medium, specifically to farmers for mental health help-seeking. The findings could be utilised in the design process to create interventions that are more likely to have an impact, specific for farmers to improve their mental health help-seeking behaviour

Farmers are not seeking help: what does service provision have to do with it?

Aim The rate of suicide in farmers is twice that of the general population. Help-seeking from health professionals, if this occurs in a timely manner, can significantly minimise the negative consequences of mental ill-health. However, it has now been demonstrated that farmers as a group are reluctant to seek help for mental ill-health, which likely contributes to this problem. Previous research has demonstrated that General Practitioners are the most commonly visited health professional in rural farming areas, however, they are under-utilised as a means of seeking help. This research aimed to examine the potential barriers and facilitators of mental health help-seeking in farmers, that relate to the provision of service from the perspective of farmers. Methods The present research draws on findings from semi‐structured interviews with 10 farmers residing in Queensland. The techniques of Braun and Clarke (2006) were used to guide the thematic analysis. Results Several key factors relating to services were identified as having the potential to directly or indirectly influence mental health help-seeking. These include: how services are marketed/packaged and delivered, availability and accessibility, continuity of care, having ‘knowledgeable bush practitioners’ as well as perception of good outcomes. Conclusion It is expected that this research will create a better understanding of the farmers’ perspective relating to service provision for the purpose of seeking help for mental health. The outcomes have implications for developing and providing interventions for farmers to promote services for the purpose of mental health help-seeking as well as create awareness in service provider and other stakeholders of issues that prevent timely help-seeking

High resolution observations of the outer disk around T Cha: the view from ALMA

T Cha is a young star surrounded by a transitional disk with signatures of planet formation. We have obtained high-resolution and high-sensitivity ALMA observations of T Cha in the ${\rm CO}(3$--$2)$, ${\rm ^{13}CO}(3$--$2)$, and ${\rm CS}(7$--$6)$ emission lines to reveal the spatial distribution of the gaseous disk around the star. In order to study the dust within the disk we have also obtained continuum images at 850$\mu$m from the line-free channels. We have spatially resolved the outer disk around T Cha. Using the CO(3-2) emission we derive a radius of $\sim$230 AU. We also report the detection of the $^{13}$CO(3-2) and the CS(7-8) molecular emissions, which show smaller radii than the CO(3-2) detection. The continuum observations at 850$\mu$m allow the spatial resolution of the dusty disk, which shows two emission bumps separated by $\sim$40AU, consistent with the presence of a dust gap in the inner regions of the disk, and an outer radius of $\sim$80AU. Therefore, T Cha is surrounded by a compact dusty disk and a larger and more diffuse gaseous disk, as previously observed in other young stars. The continuum intensity profiles are different at both sides of the disk suggesting possible dust asymmetries. We derive an inclination of i(deg)=67$\pm$5, and a position angle of PA (deg)= 113$\pm$6, for both the gas and dust disks. The comparison of the ALMA data with radiative transfer models shows that the gas and dust components can only be simultaneously reproduced when we include a tapered edge prescription for the surface density profile. The best model suggests that most of the disk mass is placed within a radius of $R<$ 50AU. Finally, we derive a dynamical mass for the central object of $M_{*}$=1.5$\pm$0.2M$_{\odot}$, comparable to the one estimated with evolutionary models for an age of $\sim$10Myr.Comment: 5 pages, 5 figures, accepted for publication in A&A Letter

The Keck Aperture Masking Experiment: spectro-interferometry of 3 Mira Variables from 1.1 to 3.8 microns

We present results from a spectro-interferometric study of the Miras o Cet, R Leo and W Hya obtained with the Keck Aperture Masking Experiment from 1998 Sep to 2002 Jul. The spectrally dispersed visibility data permit fitting with circularly symmetric brightness profiles such as a simple uniform disk. The stellar angular diameter obtained over up to ~ 450 spectral channels spaning the region 1.1-3.8 microns is presented. Use of a simple uniform disk brightness model facilitates comparison between epochs and with existing data and theoretical models. Strong size variations with wavelength were recorded for all stars, probing zones of H2O, CO, OH, and dust formation. Comparison with contemporaneous spectra extracted from our data show a strong anti-correlation between the observed angular diameter and flux. These variations consolidate the notion of a complex stellar atmosphere consisting of molecular shells with time-dependent densities and temperatures. Our findings are compared with existing data and pulsation models. The models were found to reproduce the functional form of the wavelength vs. angular diameter curve well, although some departures are noted in the 2.8-3.5 micron range.Comment: 10 pages, 10 figures Accepted to Ap

A close halo of large transparent grains around extreme red giant stars

Intermediate-mass stars end their lives by ejecting the bulk of their envelope via a slow dense wind back into the interstellar medium, to form the next generation of stars and planets. Stellar pulsations are thought to elevate gas to an altitude cool enough for the condensation of dust, which is then accelerated by radiation pressure from starlight, entraining the gas and driving the wind. However accounting for the mass loss has been a problem due to the difficulty in observing tenuous gas and dust tens of milliarcseconds from the star, and there is accordingly no consensus on the way sufficient momentum is transferred from the starlight to the outflow. Here, we present spatially-resolved, multi-wavelength observations of circumstellar dust shells of three stars on the asymptotic giant branch of the HR diagram. When imaged in scattered light, dust shells were found at remarkably small radii (<~ 2 stellar radii) and with unexpectedly large grains (~300 nm radius). This proximity to the photosphere argues for dust species that are transparent to starlight and therefore resistant to sublimation by the intense radiation field. While transparency usually implies insufficient radiative pressure to drive a wind, the radiation field can accelerate these large grains via photon scattering rather than absorption - a plausible mass-loss mechanism for lower-amplitude pulsating stars.Comment: 13 pages, 1 table, 6 figure

Phenylethanoid glycosides from Scutellaria galericulata

From the aerial parts of Scutellaria galericulata L., four phenylethanoid glycosides, 2-(4-hydroxyphenyl)-ethyl-(6-O-caffeoyl)-\beta -D-glucopyranoside (1), calceolarioside B (2), osmanthuside E (3) and martynoside (4), were isolated. The structure elucidations of the isolated compounds were performed by spectroscopic (UV, IR, ESI-MS, 1D- and 2D-NMR) methods. Compounds 1-4 demonstrated scavenging properties toward the 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical in TLC autographic assays
