The World Wide Web, and online social networks in particular, have increased connectivity between people such that information can spread to millions of people in a matter of minutes. This form of online collective contagion has provided many benefits to society, such as providing reassurance and emergency management in the immediate aftermath of natural disasters. However, it also poses a potential risk to vulnerable Web users who receive this information and could subsequently come to harm. One example of this would be the spread of suicidal ideation in online social networks, about which concerns have been raised. In this paper we report the results of a number of machine classifiers built with the aim of classifying text relating to suicide on Twitter. The classifier distinguishes between the more worrying content, such as suicidal ideation, and other suicide-related topics such as reporting of a suicide, memorial, campaigning and support. It also aims to identify flippant references to suicide. We built a set of baseline classifiers using lexical, structural, emotive and psychological features extracted from Twitter posts. We then improved on the baseline classifiers by building an ensemble classifier using the Rotation Forest algorithm and a Maximum Probability voting classification decision method, based on the outcome of base classifiers. This achieved an F-measure of 0.728 overall (for 7 classes, including suicidal ideation) and 0.69 for the suicidal ideation class. We summarise the results by reflecting on the most significant predictive principle components of the suicidal ideation class to provide insight into the language used on Twitter to express suicidal ideation.

It is widely recognized as problematic that there are generally low levels of engagement with child welfare services from biological and social fathers. The result can be limited resources for children's care and potentially poor risk assessment and management. This paper reviews the published research from 2000 to 2010 about the barriers to and facilitators of better father engagement, as well as the very limited evidence on the effectiveness of work with maltreating fathers. There is relatively little known about what works in engaging men, but there are some promising indicators from family support and child protection practice contexts. These include early identification and early involvement of fathers; a proactive approach, including an insistence on men's involvement with services; and the use of practical activities. In the light of what is known about the characteristics of maltreating fathers, there is a logical fit with cognitive‐behavioural approaches. Although there is no direct evidence of the effectiveness of motivational interviewing in this context, its effectiveness in allied fields of practice would suggest that it may hold some promise for the initial engagement of fathers who pose a risk to children.

This paper reports on findings from qualitative research conducted in the UK that sought to explore the connections between sexual identities and self-destructive behaviours in young people. International evidence demonstrates that there are elevated rates of suicide and alcohol abuse amongst lesbian, gay, bisexual and transgender (LGBT) youth. Rarely included in this body of research are investigations into young LGBT people's views and experiences of self-destructive behaviours. Data from interviews and focus groups with young LGBT participants suggest a strong link between homophobia and self-destructive behaviours. Utilising a discourse analytic approach, we argue that homophobia works to punish at a deep individual level and requires young LGBT people to manage being positioned, because of their sexual desire or gendered ways of being, as abnormal, dirty and disgusting. At the centre of the complex and multiple ways in which young LGBT people negotiate homophobia are 'modalities of shame-avoidance' such as: the routinization and minimizing of homophobia; maintaining individual 'adult' responsibility; and constructing 'proud' identities. The paper argues that these strategies of shame-avoidance suggest young LGBT people manage homophobia individually, without expectation of support and, as such, may make them vulnerable to self-destructive behaviours.

The research presented in this paper set out to explore the cultural context of youth suicide and more specifically any connections between sexual identity and self-destructive behaviour, in the light of international evidence about the disproportionate risk of suicidal thoughts and suicide attempts in lesbian, gay, bisexual and transgender (LGBT) young people. The empirical basis for the paper is qualitative research that was carried out in the North West of England and South Wales. Focus groups and interviews were conducted with a total of 69 young people, with a purposive sample to reflect diversity of sexual identity, social class and regional and rural-urban location. The paper presents a thematic analysis of the data specifically relating to the experiences of LGBT young people. A range of strategies that LGBT young people employ in the face of distress are described. These are categorised as resilience, ambivalence and self-destructive behaviour (including self-harm and suicide). The potential implications for health and social care of these strategies include the need for ecological approaches and for sexual cultural competence in practitioners, as well as prioritisation of LGBT risk within suicide prevention policies.
