New data on internal morphology of exceptionally preserved Nannirhynchia pygmaea (Morris, 1847) from the Lusitanian Basin (Brachiopoda, Early Jurassic, Portugal)

Pyritized internal moulds of articulated shells of the Early Jurassic brachiopod taxon <i>Nannirhynchia pygmaea</i> were found in beds closely below the early Toarcian oceanic anoxic event in the <i>Polymorphum</i> Zone in Portugal. The material allows a detailed study of the outline of the muscle fields, the length and direction of the crura, and the orientation of the cardinalia, which are hitherto undescribed. Three-dimensional reconstructions of articulated shells of <i>N. pygmaea</i> occurring in a single horizon were produced to show the orientation and length of arcuiform crura. The preservation of internal moulds together with the three-dimensional reconstruction of the internal shell morphology allow a more precise description of the internal morphology of this taxon than it is possible with articulated shells and serial sections. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.201200005" target="_blank">10.1002/mmng.201200005</a

Understanding Data Search as a Socio-technical Practice

Open research data are heralded as having the potential to increase effectiveness, productivity, and reproducibility in science, but little is known about the actual practices involved in data search. The socio-technical problem of locating data for reuse is often reduced to the technological dimension of designing data search systems. We combine a bibliometric study of the current academic discourse around data search with interviews with data seekers. In this article, we explore how adopting a contextual, socio-technical perspective can help to understand user practices and behavior and ultimately help to improve the design of data discovery systems.Comment: 19 pages, 3 figures, 7 table

The association between bullying‐victimisation and sleep disturbances in adolescence: Evidence from a twin study

Bullying‐victimisation has been associated with sleep disturbances. This study investigated the degree to which subtypes of bullying‐victimisation in adolescence are linked with sleep disturbances. Genetic and environmental contributions underlying bullying‐victimisation and sleep disturbances were investigated. Participants (3,242–5,076 pairs) from a longitudinal community twin study reported on their bullying‐victimisation at the age of 14 years, and sleep quality and insomnia symptoms at age 16. Regression analyses were used, accounting for the role of individual and family factors. Structural equation twin model fitting was conducted. Bullying‐victimisation was modestly associated with sleep quality and insomnia symptoms (r = 0.22–0.23) and a similar strength of associations was found across bullying‐victimisation subtypes (r = 0.11–0.22). Bullying‐victimisation, sleep quality and insomnia symptoms were predominantly influenced by genes (25–59%) and non‐shared environments (40–62%). The association between bullying‐victimisation and sleep quality was explained by genetic and non‐shared environmental influences. For insomnia symptoms and sleep quality, the association with bullying‐victimisation was in part explained by a genetic overlap. Associations between bullying‐victimisation and sleep disturbances are not limited to specific aspects of bullying‐victimisation but appear to exist for all subtypes. These findings stimulate research questions regarding the mechanisms underlying these links. For example, could certain heritable traits, such as temperament, increase vulnerability to experiencing sleep disturbances and being bullied? Research on bullying and sleep should aim to take the role of genetic predisposition into account, while also noting that it is not the only causal influence. Understanding more about these pathways could strengthen the development of techniques to prevent these difficulties from occurring

Lay health worker led intervention for depressive and anxiety disorders in India: impact on clinical and disability outcomes over 12 months.

BACKGROUND: Depressive and anxiety disorders (common mental disorders) are the most common psychiatric condition encountered in primary healthcare. AIMS: To test the effectiveness of an intervention led by lay health counsellors in primary care settings (the MANAS intervention) to improve the outcomes of people with common mental disorders. METHOD: Twenty-four primary care facilities (12 public, 12 private) in Goa (India) were randomised to provide either collaborative stepped care or enhanced usual care to adults who screened positive for common mental disorders. Participants were assessed at 2, 6 and 12 months for presence of ICD-10 common mental disorders, the severity of symptoms of depression and anxiety, suicidal behaviour and disability levels. All analyses were intention to treat and carried out separately for private and public facilities and adjusted for the design. The trial has been registered with clinical trials.gov (NCT00446407). RESULTS: A total of 2796 participants were recruited. In public facilities, the intervention was consistently associated with strong beneficial effects over the 12 months on all outcomes. There was a 30% decrease in the prevalence of common mental disorders among those with baseline ICD-10 diagnoses (risk ratio (RR) = 0.70, 95% CI 0.53-0.92); and a similar effect among the subgroup of participants with depression (RR = 0.76, 95% CI 0.59-0.98). Suicide attempts/plans showed a 36% reduction over 12 months (RR=0.64, 95% CI0.42–0.98) among baseline ICD-10 cases. Strong effects were observed on days out of work and psychological morbidity, and modest effects on overall disability [corrected]. In contrast, there was little evidence of impact of the intervention on any outcome among participants attending private facilities. CONCLUSIONS: Trained lay counsellors working within a collaborative-care model can reduce prevalence of common mental disorders, suicidal behaviour, psychological morbidity and disability days among those attending public primary care facilities

Auto Emotion: Autobiography, Emotion and Self-fashioning

Mining the territory of autobiographical and biographical genres, Auto Emotion highlights the theatrical nature of self-expression. Rather than present emotional expression as an authentic or spontaneous outpouring, it highlights how emotion is produced and presented, packaged and performed. In artworks that draw attention to the public appetite for confession and catharsis, the exhibition questions the idea of the artist as a bearer of subjectivity and authenticity. Working with – and against – tropes, genres and stereotypes of emotional display, the exhibition depicts feelings that range from longing and heartbreak, bereavement and revenge, and emotional states including anger, frustration, abjection, nostalgia, psychosis, and regret. The exhibition highlights the external factors that can trigger outbursts of feeling, from psychotropic drugs and pop music, to hypnosis or smell. Underlying these works is a concern with the boundaries between social conformism and autonomy, brain chemistry and emotion, automatic behavior and self-determination. The exhibition was accompanied by a public programme including a discussion on art, curating and affect, a screening by artists Sophie Calle and Nikki S Lee, and a performance under hypnosis, as well as a lecture, by artist Matt Mullican. The exhibition featured work by artists Marina Abramović, Reza Afisina, Eija-Liisa Ahtila, Sophie Calle, Andrea Fraser, Rodney Graham, Christian Jankowski, Yayoi Kusama, Nikki S. Lee, Rafael Lozano-Hemmer, Matt Mullican, Benny Nemerofsky Ramsay, Adrian Paci, Johannes Wohnseife

The Genesis 12–19 (G1219) Study: A Twin and Sibling Study of Gene–Environment Interplay and Adolescent Development in the UK

The Genesis 12–19 (G1219) Study is an ongoing longitudinal study of a sample of UK twin pairs, non-twin sibling pairs, and their parents. G1219 was initially designed to examine the role of gene–environment interplay in adolescent depression. However, since then data have continued to be collected from both parents and their offspring into young adulthood. This has allowed for longitudinal analyses of depression and has enabled researchers to investigate multiple phenotypes and to ask questions about intermediate mechanisms. The study has primarily focused on emotional development, particularly depression and anxiety, which have been assessed at multiple levels of analysis (symptoms, cognitions, and relevant environmental experiences). G1219 has also included assessment of a broader range of psychological phenotypes ranging from antisocial behaviors and substance use to sleep difficulties, in addition to multiple aspects of the environment. DNA has also been collected. The first wave of data collection began in the year 1999 and the fifth wave of data collection will be complete before the end of 2012. In this article, we describe the sample, data collection, and measures used. We also summarize some of the key findings to date
