RESUMO

Elite athletes, coaches and high-performance staff are exposed to a range of stressors that have been shown to increase their susceptibility to experiencing mental ill-health. Despite this, athletes may be less inclined than the general population to seek support for their mental health due to stigma, perceptions of limited psychological safety within sport to disclose mental health difficulties (e.g., selection concerns) and/or fears of help-seeking signifying weakness in the context of high performance sport. Guidance on the best ways to promote mental health within sporting environments is increasing, though current frameworks and position statements require greater focus on a whole of system approach, in which the needs of athlete, coaches and high-performance staff are considered within the context of the broader ecological system in which they operate and perform. This paper synthesizes existing research, reviewed for translatability by mental health professionals working in elite sport, to provide an evidence-informed framework with real world utility to promote mentally healthy environments for all stakeholders in elite sporting organizations, from athletes through to administrators. Recommendations are provided to positively impact the mental wellbeing of athletes and support staff, which may in turn influence athletic performance. This framework is intended to provide sporting organizations with evidence-informed or best practice principles on which they can develop or progress their policies to support mental health promotion and prevent the onset of mental health difficulties. It is intended that the framework can be adapted or tailored by elite sporting organizations based upon their unique cultural, contextual and resourcing circumstances.

RESUMO

The production of MOFs at large scale in a sustainable way is key if these materials are to be exploited for their promised widespread application. Much of the published literature has focused on demonstrations of preparation routes using difficult or expensive methodologies to scale. One such MOF is nano-zeolitic imidazolate framework-8 (ZIF-8) - a material of interest for a range of possible applications. Work presented here shows how the synthesis of ZIF-8 can be tracked by a range of methods including X-ray diffraction, thermo gravimetric analysis and inelastic neutron scattering - which offer the prospect of in-line monitoring of the synthesis reaction. Herein we disclose how the production of nano-ZIF-8 can be conducted at scale using the intermediate phase ZIF-L. By understanding the economics and demonstrating the production of 1 kg of nano-ZIF-8 at pilot scale we have shown how this once difficult to make material can be produced to specification in a scalable and cost-efficient fashion.

RESUMO

Polybenzimidazole (PBI) is a promising and suitable membrane polymer for the separation of the H2/CO2 pre-combustion gas mixture due to its high performance in terms of chemical and thermal stability and intrinsic H2/CO2 selectivity. However, there is a lack of long-term separation studies with this polymer, particularly when it is conformed as hollow fibre membrane. This work reports the continuous measurement of the H2/CO2 separation properties of PBI hollow fibres, prepared as mixed matrix membranes with metal-organic framework (MOF) ZIF-8 as filler. To enhance the scope of the experimental approach, ZIF-8 was synthesized from the transformation of ZIF-L upon up-scaling the MOF synthesis into a 1 kg batch. The effects of membrane healing with poly(dimethylsiloxane), to avoid cracks and non-selective gaps, and operation conditions (use of sweep gas or not) were also examined at 200°C during approximately 51 days. In these conditions, for all the membrane samples studied, the H2 permeance was in the 22-47 GPU range corresponding to 22-32 H2/CO2 selectivity values. Finally, this work continues our previous report on this type of application (Etxeberria-Benavides et al. 2020 Sep. Purif. Technol. 237, 116347 (doi:10.1016/j.seppur.2019.116347)) with important novelties dealing with the use of ZIF-8 for the mixed matrix membrane coming from a green methodology, the long-term gas separation testing for more than 50 days and the study on the membrane operation under more realistic conditions (e.g. without the use of sweep gas).

RESUMO

The effect of different deprotonators as well as washing steps and drying procedure on the synthesis of ZIF-8 from the mother liquor was investigated. The morphology, thermal stability, crystallinity, and surface area of the synthesized MOF were investigated. In addition, life-cycle assessment (LCA) or, in other words, eco-balance, was implemented as well. LCA compares the full range of environmental effects associated with the product by evaluating all inputs and outputs of material flows and predicting how such flow will affect the environment. ZIF-8 nanocrystals were synthesized from the recycled mother liquors using NaOH or NH4OH thus preserving the main characteristics of the ZIF-8 nanoparticles derived from the initial synthesis. The rest of the characterization methods confirmed the suitability of the synthesis methodology considering the phase purity of the obtained ZIF-8 and nanometer size particles. This procedure enabled us not only to obtain phase pure ZIF-8 but also to substantially decrease the amount of solvent used for washing making it a sustainable process.

RESUMO

The influential Victorian appellate judgment of R v Verdins [2007] VSCA 102 provided a sentencing framework for "impaired mental functioning" not only in Victoria but in other Australian jurisdictions. Following the judgment of Director of Public Prosecutions (Vic) v O'Neill (2015) 47 VR 395; [2015] VSCA 325, it appeared that personality disorders were not considered within the scope of the Verdins principles. In Brown v The Queen [2020] VSCA 212, the decision of the Victorian Court of Appeal broadened the potential for impaired mental functioning to include personality disorders as relevant to moral culpability. However, it is also noted that there are several limits on this.

RESUMO

In 2014, the Crimes (Mental Impairment and Unfitness to be Tried) Act 1997 in Victoria was extended to the Children's Court of Victoria. This article describes the processes that preceded this change and the changes that occurred. The potential opportunities consequent to the changes are described, with their corresponding ethical implications. The decision not to resource some of the changes as recommended by the Victorian Law Reform Commission is described, with reference to the lack of establishment of an adolescent forensic mental health facility. The shortfalls currently occurring and their ethical implications are also discussed. We note the need for data regarding the number of children whose matters are being heard under the Crimes (Mental Impairment and Unfitness to be Tried) Act 1997, and the resourcing implications that flow from this.

RESUMO

For many years, solitary confinement has been a contentious correctional intervention. This column explores the evidence that solitary confinement harms mental health, and reviews some of the international and local perspectives on the practice. Recommendations are made to end solitary confinement, contending that this is to the benefit of prisoners and prisons, as well as the communities to which prisoners will return. Solitary confinement is increasingly subject to opprobrium from health professionals and representative organisations, as well as being the subject of more rigorous recommendations in international instruments. The column proposes greater involvement of mental health professionals, systemic research to reduce solitary confinement, and programs of external review and scrutiny. Such measures are consistent with international instruments and would bring Australia into line with contemporary thinking about conditions of incarceration.

RESUMO

OBJECTIVE: The aim of the present study was to describe characteristics and post-release outcomes of Victorian homicide offenders under the Crimes (Mental Impairment and Unfitness to be Tried) Act 1997 (and/or its forerunner legislation) released from forensic inpatient psychiatric care since the development of specialist forensic services. METHOD: A legal database identified subjects meeting inclusion criteria: hospitalized in forensic psychiatric care due to finding of mental impairment or unfitness to stand trial for homicide in Victoria; released into the community; and released between 1 January 1991 and 30 April 2002. Using clinical records, demographics, index offence, progress in hospital, diagnosis, psychosocial and criminological data were obtained. Outcomes (offending or readmission into secure care) were obtained from the clinical records. RESULTS: Of the 25 subjects, 19 (76%) were male. Primary diagnoses on admission to forensic hospital care were schizophrenia, n = 16 (64%); other psychotic disorder, n = 5 (20%); depression, n = 3 (12%); and personality disorder, n = 1 (4%). Mean time in custodial supervision was 11 years and 2 months, less for those whose offence occurred after the development of forensic rehabilitation services. In the first 3 years after release, there was a single episode of criminal recidivism, representing a recidivism rate of 1 in 25 (4%) over 3 years. Twelve subjects (48%) were readmitted at some point in the 3 year follow up. CONCLUSION: There was a very low rate of recidivism after discharge, but readmissions to hospital were common. Lengths of custodial care were reduced after the introduction of forensic rehabilitation facilities. Recidivism is low when there are well-designed and implemented forensic community treatment programmes, consistent with other data suggesting a reciprocal relationship between safe community care and a low threshold for readmission to hospital, lessening re-offending at times of crisis. Further research should be directed at timing of release decisions, based on reducing identified risk factors to acceptable levels.
