Questions 46 t0 50 are based on the following passage.
Open data-sharers are still in the minority in many fields,Although many
rescarechers broadly agree that public access to raw data would accelerate
science- because other scientists might be able to make advances not foreseen by
the data's producers -most are reluctant to post the results of their own
labours online (see Nature 461, 160-163; 2009) When Wolkovich, for instance,
went hunting for the data from the 50 studies in her meta-analysis, only 8 data
sets were available online, and many of the researchers whom she e-mailed
refused to share their work Forced to extract data from tables or flgures in
publications,Wolkovich's team could conduct only limited analyses
Some communities have agreed to share online - geneticists, for example,
post DNA sequences at the GenBank repository, and astronomers are accustomed to
accessing images of galaxies and stars from, say,the Sloan Digital Sky Survey, a
telescope that has observed some 500 million objects - but these remain the
exception, not the rule Historically, scientists have objected to sharing for
many reasons: it is a lot of work; until recently, good databases did not exist;
grant funders were not pushing for sharing; it has been difficult to agree on
standards for formatting data and the contextual information called metadata;
and there is no agreed way to assign credit for data
But the barriers are disappearing in part because journals and funding
agencies worldwide are encouraging scientists to make their data public. Last
year, the Royal Society in London said in its report Science as an Open
Enterprise that scientists need to shift away from a research culture where data
is viewed as pricate preserve " Funding agencies note that data paid for with
public money should be public information, and the scientific community is
recognizing that data can now be shared digitally in ways that were not possible
before To match the growing demand, services are springing up to make it easier
to publish research products online and enable other researchers to discover and
cite them
Although exhortations to share data often concentrate on the moral
advantages of sharing, the practice is not purely altruistic Researchers who
share get plenty of personal benefits.including more connections with
colleagues,improved visibility and increased citations The most successful
sharers - those whose data are downloaded and cited the most often - get
noticed, and their work gets used For example, one of the most popular data sets
on multidisciplinary repository Dryad is about wood density around the world; it
has been downloaded 5,700 times. Co-author Amy Zanne, a biologist at George
Washington University in Washington DC, thinks that users probably range from
climate-change researchers wanting to estimate how much carbon is stored in
biomass, to foresters looking for information on different grades of' timber "I
would much prefer to have my data used by the maximum number of people to ask
their own questions," she says "It's important to allow readers and reviewers to
see exactly how you arrive at your results Publishing data and code allows your
science to be reproducible "
