Addressing the Security Requirements in Functional Safety Standard IEC 61511-1:2016

PresentationThe 2016 edition of IEC 61511-1: 2016 added two new requirements regarding the security of safety instrumented systems (SIS). The first requirement states that “a security risk assessment shall be carried out to identify the security vulnerabilities of the SIS” and the second requirement states that “the design of the SIS shall be such that it provides the necessary resilience against the identified security risks”. The standard directs the reader to ISA TR84.00.09, ISO/IEC 27001:2013, and IEC 62443-2-1:2010 for further guidance on how to comply with these requirements. While these documents are informative, the 479 combined pages do not provide concise guidance on how to address the specific security requirements. The purpose of this paper is to offer step-by-step guidance on how to address the security requirements in 61511 and to identify specific clauses in the reference standards for further information

Recovery approaches in mental health : A qualitative evaluation of the Whole Life Therapy programme for persons with schizophrenia

This work and the related PDF file are licensed under a Creative Commons Attribution 4.0 International LicenseThe recovery approach within mental health services has in recent years been influential in promoting more active participation from service users concerning their treatment and progress, within a move towards models of interventions based on social models and ideas of service user empowerment. Although mental health recovery models are often heralded as ideological goals, comparatively little has been documented about the means of achieving these. This article sets out the nature and content of the Whole Life Programme, used within the Hertfordshire NHS Partnership Foundation Trust, and the results of qualitative research into the programme that set out to analyse the impact of its delivery from the perspectives of service users. The research examined the experiences and views of participants receiving treatment several months after the completion of the programme, and also of those who withdrew prematurely, in order to learn from these experiences, adding to our understanding of how one recovery based approach, the Whole Life Manual, can be applied in practiceNon peer reviewedFinal Published versio

See: http://creativecommons.org/licenses/by-nc/4.0/Sex differences in neurocognitive abilities have been extensively explored both in the healthy population and in many disorders. Until recently, however, little work has examined such differences in people with Alzheimer's disease (AD). This is despite clear evidence that AD is more prevalent in women, and converging lines of evidence from brain imaging, post-mortem analyses, hormone therapy and genetics suggesting that AD affects men and women differently. We provide an overview of evidence attesting to the poorer cognitive profiles in women than in men at the same stage of AD. Indeed, men significantly outperform women in several cognitive domains, including: Language and semantic abilities, visuospatial abilities and episodic memory. These differences do not appear to be attributable to any differences in age, education, or dementia severity. Reasons posited for this female disadvantage include a reduction of estrogen in postmenopausal women, greater cognitive reserve in men, and the influence of the apolipoprotein E ε4 allele. Assessment of cognitive abilities contributes to the diagnosis of the condition and thus, it is crucial to identify the role of sex differences if potentially more accurate diagnoses and treatments are to emerge.Peer reviewedFinal Published versio

Clinical correlates of tobacco smoking in OCD: A UK, case-controlled, exploratory analysis

Background: Obsessive-compulsive disorder (OCD) is a biologically heterogeneous neuropsychiatric disorder. It is associated with impulsive as well as compulsive neurocognitive mechanisms. Cigarette smoking is common among most psychiatric patients; however, OCD patients are thought to show reduced rates. OCD smokers may thus represent a relatively uncommon OCD subtype, characterised by increased impulsivity. In this study, we aim to establish the prevalence of smoking in a large, well-defined OCD cohort. We investigate whether smokers with OCD differ from non-smokers with OCD on clinical measures of behavioural impulsivity and domains of personality and temperament, including reward-dependence and novelty-seeking. Method: 183 of 200 outpatients with DSM-IV OCD were interviewed to determine smoking status. A sub-sample of 10 smokers was compared with 10 non-smokers, pair wise matched for age and gender. Patients were assessed for DSM co-morbidity, symptom profile, OCD severity, behavioural impulsivity and personality dimensions. Results: Only 10 individuals (5.46%; five males) were smokers. Compared to OCD non-smokers, OCD smokers scored significantly higher on the Barratt Impulsiveness Scale (p < 0.001). They also scored significantly higher on TCI measures of novelty seeking (p < 0.001) and reward dependence (p < 0.001) and significantly lower on measures of harm avoidance (p < 0.001). Conclusions: Tobacco smoking is rare in OCD. Significantly higher levels of behavioural impulsivity and temperamental factors associated with reward driven impulsivity are seen in OCD smokers compared to non-smokers. Tobacco smoking may indicate a possible source of neurocognitive heterogeneity in OCD

CLASSIFICATION OF RISK IN PSYCHIATRY

Psychiatric risk-assessments generally quantify risk using broad, categorical, indicators (e.g., high-risk, low-risk). We examined reliability of such indicators when applied by mental-health professionals. Four versions of a questionnaire were used, each specifying a different clinical outcome along with a range of different probabilities at which that outcome might occur. Respondents classified each probability, allowing a comparison of the level of likelihood at which different professionals would apply the terms \u27high-risk\u27, \u27medium-risk\u27 and \u27low-risk\u27. We found little consistency among professionals who assessed risk for the same outcomes. Moreover, there were also large and unpredicted differences in response-profiles between the 4 clinical outcomes. These findings raise concerns about the communication value of current risk-assessment terminology

Student aspirations for higher education in Central Queensland : a survey of school students’ navigational capacities

In recent times, student aspiration for higher education has become the subject of Australian Government policy and school/university partnerships. A perceived shortfall in aspiration for higher education – particularly by under-represented groups – is seen to be frustrating the achievement of the Government’s targets for universities

Student preferences for bachelor degrees at TAFE: the socio-spatial influence of schools

This report on Student Preferences for Bachelor Degrees at TAFE (Technical and Further Education) institutions is derived from research commissioned by Australia&rsquo;s National Centre for Student Equity in Higher Education (NCSEHE) hosted at Curtin University and conducted by researchers at Deakin University&rsquo;s Strategic Centre for Research in Educational Futures and Innovation (CREFI). The report focuses on the influence of schools on their students&rsquo; higher education (HE) preferences &ndash; particularly their preferences for TAFE bachelor degrees &ndash; as recorded by the Victorian and South Australian Tertiary Admissions Centres (VTAC and SATAC). Influence is researched in terms of a school&rsquo;s socioeconomic status, geographical location and sector. The SATAC data set is considerably smaller, at around 8 per cent of the VTAC data set.Bachelor degrees offered by TAFEs are relatively small in number but a growing higher education option for students in Australia (Gale et al. 2013). The Australian Government&rsquo;s proposal to extend Commonwealth Supported Places (CSPs) to include Australian higher education not delivered by the nation&rsquo;s public universities (Department of Education 2014b), is likely to fuel further growth in TAFE bachelor degree offerings. The recent Report of the Review of the Demand Driven Funding System in Australian higher education (Kemp &amp; Norton 2014), which recommended this change, also makes special mention of non-university degree options as something that would be of particular benefit to students from low socioeconomic status backgrounds.The research reported herein is informed by a review of the international research literature, which indicates three main influences on students&rsquo; HE preferences: (1) students&rsquo; families and communities; (2) the socio-spatial location of their schools; and (3) school practices. This report contributes to understandings on the second of these: the influence of school context (their socio-spatial location) on students&rsquo; preferences for TAFE bachelor degrees.The research found that the annual rate of student preferences for TAFE bachelor degrees was relatively stable (at around 1,500 per annum) from 2009 to 2012 but rose significantly (by 30%) in 2013. Students from high socioeconomic status schools (and with an average ATAR of 56.9) were the group that registered the largest number of preferences. The number of preferences for TAFE bachelor degrees lodged by students from metropolitan schools exceeded the preferences of students from schools located in all other regions combined. This might reflect the fact that TAFE institutions offering bachelor degrees tend to be located in metropolitan areas.The research also found that students&rsquo; preferences for TAFE bachelor degrees increased after announcement of their Australian Tertiary Admission Rank (ATAR), by between 25 and 30 per cent each year. The post-ATAR increase was most noticeable in the Health and Education fields of study and among students from high socioeconomic status schools. The report concludes that while the public perception of TAFE is that it is a sector primarily for students from low SES backgrounds, this is not reflected in students&rsquo; preferences for TAFE bachelor degrees. Instead, the preferences of students from high socioeconomic schools outnumber other SES groups in almost every TAFE-degree field of study. This includes the fields of Health and Education, which are often seen to be typical low SES student choices in universities (Gale &amp; Parker 2013)

Psychosis and Human Rights: Conflicts in Mental Health Policy and Practice

This paper examines conflicts in polices in England and Wales pertaining to the demand for alternative, non-medical crisis support for those experiencing ‘psychosis’. We examine the limitations of current treatment, policy and legislative frameworks in supporting these demands. In particular, we focus on the limitations of prevailing conceptualisations of ‘human rights’, ‘social inclusion’ and ‘recovery’. These concepts, we argue, are embedded within a broader treatment framework which renders medication as mandatory and all other treatment modalities as inherently subsidiary, and a broader policy framework which is complicit with bio-medical orthodoxies of ‘mental illness’ and prioritises treatment compliance and compulsion. Therefore, in order to advance a ‘human rights’ approach to mental health policy, we argue that reigning orthodoxies inherent within policy and practice must be explicitly challenged to open up spaces for the availability of alternatives

Childhood trauma and schizotypy in non-clinical samples: A systematic review and meta-analysis

© 2022 Toutountzidis et al. This is an open access article distributed under the Creative Commons Attribution License, to view a copy of the license, see: https://creativecommons.org/licenses/by/4.0/The association of early life adversities and psychosis symptoms is well documented in clinical populations; however, whether this relationship also extends into subclinical psychosis remains unclear. In particular, are early life adversities associated with increased levels of schizotypal personality traits in non-clinical samples? We conducted a systematic review and meta-analysis of associations between early life adversities and psychometrically defined schizotypal traits in non-clinical samples. The review followed PRISMA guidelines. The search using PubMed, Web of Science and EBSCO databases identified 1,609 articles in total. Twenty-five studies (N = 15,253 participants) met eligibility criteria for the review. An assessment of study quality showed that fewer than half of all studies were rated as methodologically robust. Meta-analyses showed that all forms of childhood abuse (emotional, physical and sexual) and neglect (emotional and physical) were significantly associated with psychometric schizotypy. The association of schizotypy traits with childhood emotional abuse (r = .33: 95%CI .30 to .37) was significantly larger than for all other form of abuse or neglect. Meta-regression analyses showed that the physical abuse-schizotypy relationship was stronger in samples with more women participants; and the sexual abuse-schizotypy relationship was stronger in younger samples. The current review identifies a dose-response relationship between all forms of abuse/neglect and schizotypy scores in non-clinical samples; however, a stronger association emerged for emotional abuse. More research is required to address the relationship of trauma types and specific symptom types. Future research should also address the under-representation of men.Peer reviewe
