When a close friend or relative dies by suicide: the impact on mental health and social functioning of young adults
Full text linkIntroduction: Provision of support for people bereaved by suicide has become a key priority for suicide prevention strategies in many developed countries. Few studies have measured whether suicide bereavement increases risk of suicidal behaviour compared with bereaved controls. Methods: I sampled 659,572 staff and students at 37 UK higher education institutions in 2010. Via mass email, I invited adults who had experienced a sudden bereavement to complete an online survey measuring post-bereavement suicidal ideation and attempts, and other psychosocial outcomes. Inclusion criteria were: current age 18-40 years, and sudden bereavement of a close contact since the age of 10 years. Multivariable regression was used to compare those bereaved by suicide to two reference categories: those bereaved by natural causes and those bereaved by unnatural causes. Results: Of 3,432 eligible respondents, 614 adults were bereaved by suicide, 712 by sudden unnatural causes of death, and 2,106 by sudden natural causes. Compared with adults bereaved by natural causes, adults bereaved by suicide had a similar risk of suicidal thoughts, poor social functioning, non-suicidal self-harm and incicdent depression, but a significantly increased risk of suicide attempts (AOR=1.65; 95% CI=1.12-2.42; p=0.01), drop-out from work or education, and subjective stigma. Compared with adults bereaved by unnatural causes, adults bereaved by suicide had a similar risk of all the above outcomes, except for an increased risk of poor social functioning and subjective stigma. For all the associations identified, risks were elevated in both relatives and non-relatives. Discussion: My findings suggest that there are some risk similarities in suicidality between young adults exposed to suicide bereavement and those exposed to other violent bereavements. Implications: The needs of young adults in the UK bereaved by unnatural deaths may also need consideration in suicide prevention policy

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Physical activity as an intervention in severe mental illness
Full text linkPhysical activity is a modifiable risk factor for several physical and mental health conditions. It is well established that people with severe mental illness have increased risk of physical health complications, particularly cardiovascular disease. They are also more likely to be physically inactive, contributing to the elevated cardiovascular and metabolic risks, which are further compounded by antipsychotic medication use. Interventions involving physical activity are a relatively low risk and accessible way of reducing physical health problems and weight in people with severe mental illness. They also have wider benefits for mental health symptoms and quality of life. However, many barriers still exist to the widespread implementation of physical activity interventions in the treatment of severe mental illness. A more concerted effort is needed to facilitate their translation into routine practice and to increase adherence to activity interventions
Cross-cultural attitudes to help-seeking among individuals who are suicidal: new perspective for policy-makers
Full text linkWorld Mental Health Survey data demonstrate that a high proportion of people who are suicidal receive no treatment and that, contrary to previous assumptions, attitudes to treatment constitute greater barriers to help-seeking than do stigma or structural/financial constraints. We explore how suicide-prevention policy-makers might respond to Bruffaerts et al’s findings
