Letters to a young scientist by Edward O. Wilson : interview

I am an early- to mid-career researcher, and Letters to a Young Scientist struck a chord with me from the very first page. The journey from amateur enthusiast to professional scientist is an exciting, challenging and often difficult one, and Edward Wilson - a Pulitzer prizewinner and one of the world's greatest entomologists - is well qualified to guide and advise the new generation. Written as a collection of letters filled with anecdotes and well-considered advice, this book is inspired by the author's experience of the journey from being a young boy enthused by ants to an eminent scholar. Like many in his field, Wilson's education began when he was a child fascinated by insects in the garden (my own summers spent excavating ant nests feel somewhat validated). He traces his progression through formal education to the establishment of his own scientific research programme.

Examining ‘Latinidad’ in Latin America: race, ‘Latinidad’ and the decolonial option

This article provides a critical account of the idea of race, conceived of and derived from European colonisers in the New World. The paper argues that race became a crucial category to the colonising projects of the New World, and in particular in the distribution of power during colonialism. The paper further examines how the notion of Latinidad (Latinity), entrenched in the term Latin America, continued to enact a discourse of racial superiority/inferiority even after the battles for Independence had taken place. Employing the critical vocabulary and framework of Decolonial theory, the paper introduces key arguments against Western European universality, and calls for a re-reading of the processes that structure privilege across racial and ethnic lines.

Advanced science and technology letters : advanced researches on security and assurance

We would like to welcome you to the Regular Papers proceedings of the 7th International Conference on Information Security and Assurance (ISA 2013) which was held on April 26-28, 2013 at Waterfront Airport Hotel and Casino, Cebu, Philippines. ISA 2013 is focused on various aspects of advances in researches on Security and Assurance. It provided a chance for academic and industry professionals to discuss recent progress in the related areas. We expect that the conference and its publications will be a trigger for further related research and technology improvements in this important subject. We would like to acknowledge the great effort of all the Chairs and members of the Editorial Committee. We would like to express our gratitude to all of the authors of submitted papers and to all attendees, for their contributions and participation. We believe in the need for continuing this undertaking in the future.

Analysis of serious non-AIDS events among HIV-infected adults at Latin American sites

Acquired immune deficiency appears to be associated with serious non-AIDS (SNA)-defining conditions such as cardiovascular disease, liver and renal insufficiency and non-AIDS-related malignancies. We analysed the incidence of, and factors associated with, several SNA events in the LATINA retrospective cohort.

Volatility dynamics in the term structure of Latin American sovereign international bonds

We examine the nature of volatility dynamics in the term structure of sovereign bonds issued in international markets by major Latin American countries. Focusing only on the U.S. dollar-denominated sovereign international bonds, this study shows the heterogeneous nature of volatility effects that affect the term structure of individual countries in Latin America. Considering the significance of the Argentine credit event in the region, we also account for any change in dynamics following the Argentine default in 2001 by subsampling the pre- and postdefault windows. We also find some evidence of liquidity-driven volatility interaction in the term structure.

Letters, green cards, telephone calls and postcards: systematic and meta-analytic review of brief contact interventions for reducing self-harm, suicide attempts and suicide

BACKGROUND: There is growing interest in brief contact interventions for self-harm and suicide attempt. AIMS: To synthesise the evidence regarding the effectiveness of brief contact interventions for reducing self-harm, suicide attempt and suicide. METHOD: A systematic review and random-effects meta-analyses were conducted of randomised controlled trials using brief contact interventions (telephone contacts; emergency or crisis cards; and postcard or letter contacts). Several sensitivity analyses were conducted to examine study quality and subgroup effects. RESULTS: We found 14 eligible studies overall, of which 12 were amenable to meta-analyses. For any subsequent episode of self-harm or suicide attempt, there was a non-significant reduction in the overall pooled odds ratio (OR) of 0.87 (95% CI 0.74-1.04, P = 0119) for intervention compared with control. The number of repetitions per person was significantly reduced in intervention v. control (incidence rate ratio IRR = 066, 95% CI 0.54-0.80, P<0001). There was no significant reduction in the odds of suicide in intervention compared with control (OR = 0.58, 95% CI 0.24-1.38). CONCLUSIONS: A non-significant positive effect on repeated self-harm, suicide attempt and suicide and a significant effect on the number of episodes of repeated self-harm or suicide attempts per person (based on only three studies) means that brief contact interventions cannot yet be recommended for widespread clinical implementation. We recommend further assessment of possible benefits in well-designed trials in clinical populations.
