The Google generation: the information behaviour of the researcher of the future

Abstract: Purpose – This article is an edited version of a report commissioned by the British Library and JISC to identify how the specialist researchers of the future (those born after 1993) are likely to access and interact with digital resources in five to ten years' time. The purpose is to investigate the impact of digital transition on the information behaviour of the Google Generation and to guide library and information services to anticipate and react to any new or emerging behaviours in the most effective way.Design/methodology/approach – The study was virtually longitudinal and is based on a number of extensive reviews of related literature, survey data mining and a deep log analysis of a British Library and a JISC web site intended for younger people.Findings – The study shows that much of the impact of ICTs on the young has been overestimated. The study claims that although young people demonstrate an apparent ease and familiarity with computers, they rely heavily on search engines, view rather than rea...

West Nile virus infection in birds and mosquitoes, New York State, 2000.

Abstract: West Nile (WN) virus was found throughout New York State in 2000, with the epicenter in New York City and surrounding counties. We tested 3,403 dead birds and 9,954 mosquito pools for WN virus during the transmission season. Sixty-three avian species, representing 30 families and 14 orders, tested positive for WN virus. The highest proportion of dead birds that tested positive for WN virus was in American Crows in the epicenter (67% positive, n=907). Eight mosquito species, representing four genera, were positive for WN virus. The minimum infection rate per 1,000 mosquitoes (MIR) was highest for Culex pipiens in the epicenter: 3.53 for the entire season and 7.49 for the peak week of August 13. Staten Island had the highest MIR (11.42 for Cx. pipiens), which was associated with the highest proportion of dead American Crows that tested positive for WN virus (92%, n=48) and the highest number of human cases (n=10).

Social media use in the research workflow

Abstract: The paper reports on a major international survey, covering 2,000 researchers, which investigated the use of social media in the research workflow. The topic is the second to emerge from the Charleston Observatory, the research adjunct of the popular annual Charleston Conference (http://www.katina.info/conference/). The study shows that social media have found serious application at all points of the research lifecycle, from identifying research opportunities to disseminating findings at the end. The three most popular social media tools in a research setting were those for collaborative authoring, conferencing, and scheduling meetings. The most popular brands used tend to be mainstream anchor technologies or 'household brands', such as Twitter. Age is a poor predictor of social media use in a research context, and humanities and social science scholars avail themselves most of social media. Journals, conference proceedings, and edited books remain the core traditional means of disseminating research, with institutional repositories highly valued as well, but social media have become important complementary channels for disseminating and discovering research.

Social media use in the research workflow

Abstract: The paper reports on a major international questionnaire survey that investigated the use of social media in the research workflow. The topic is the second to emerge from the Charleston Observatory. The study of more than 2000 researchers shows that social media impact on all points of the research lifecycle, from identifying research opportunities to disseminating findings at the end. The three most popular social media tools in a research setting were those for collaborative authoring, conferencing, and scheduling meetings. The most popular brands used tend to be mainstream anchor technologies or 'household brands', like Twitter and Skype. Age is a poor predictor of social media use in a research context and scientists avail themselves most of social media. Journals, conference proceedings and edited books remain the core traditional means of disseminating research, with institutional repositories highly valued as well, but social media has become an important complementary channel for disseminating and discovering research.

The Design and Analysis of Experiments

Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

SPAdes, a new genome assembly algorithm and its applications to single-cell sequencing ( 7th Annual SFAF Meeting, 2012)

Abstract: The lion's share of bacteria in various environments cannot be cloned in the laboratory and thus cannot be sequenced using existing technologies. A major goal of single-cell genomics is to complement gene-centric metagenomic data with whole-genome assemblies of uncultivated organisms. Assembly of single-cell data is challenging because of highly non-uniform read coverage as well as elevated levels of sequencing errors and chimeric reads. We describe SPAdes, a new assembler for both single-cell and standard (multicell) assembly, and demonstrate that it improves on the recently released E+V-SC assembler (specialized for single-cell data) and on popular assemblers Velvet and SoapDeNovo (for multicell data). SPAdes generates single-cell assemblies, providing information about genomes of uncultivatable bacteria that vastly exceeds what may be obtained via traditional metagenomics studies. SPAdes is available online ( http://bioinf.spbau.ru/spades ). It is distributed as open source software.
