Palau also established the worlds first shark sanctuary in 2009.The tiny island nation has set aside 500,000 square kilometres80 percentof its maritime 27 , for full protection. Thats the highest percentage of an 28 economic zone devoted to marinecons

21、ervation by any country in the world. The remaining 20 percent of the Palau seas will bereserved for local fishing by individuals and small-scale 29 fishing businesses with limitedexports.“Island 30 have been among the hardest hit by the threats facing the ocean,“ said PresidentTommy Remengesau Jr.

22、in a statement. “Creating this sanctuary is a bold move that thepeople of Palau recognise as 31 to our survival. We want to lead the way in restoring the healthof the ocean for future generations.“Palau has only been an 32 nation for twenty years and has a strong history of environmentalprotection.

23、It is home to one of the worlds finest marine ecosystems, with more than 1,300 species of fish and 700 species of coral.Senator Hokkons Baules, lead 33 of the Palau National Marine Sanctuary Act, said thesanctuary will “help build a 34 future for the Palauan people by honoring the conservationtradit

27、eady momentum: a call to make research data, softwarecode and experimental methods publicly available and transparent. A spirit of openness isgaining acceptance in the science community, and is the only way, say advocates, to addressa crisis in science whereby too few findings are successfully repro

28、duced. Furthermore, they say, it is the best way for researchers to gather the range of observations that are necessary tospeed up discoveries or to identify large-scale trends.B The open-data shift poses a confusing problem for junior researchers. On the one hand, the drive to share is gathering of

29、ficial steam. Since 2013, global scientific bodies have begunto back politics that support increased public access to research. On the other hand, scientistsdisagree about how much and when they should share date, and they debate whether sharingit is more likely to accelerate science and make it mor

30、e robust, or to introduce vulnerabilitiesand problems. As more journals and make it more robust, or to introduce vulnerabilities andproblems. As more journal and funders adopt data-sharing requirements, and as a growingnumber of enthusiasts call for more openness, junior researchers must find their

31、placebetween adopters and those who continue to hold out, even asthey strive to launch their owncareers.C One key challenge facing young scientists is how to be open without becoming scientificallyvulnerable. They must determine the risk of jeopardizing a job offer or a collaborationproposal from th

32、ose who are wary ofor unfamiliar withopen science. And they must learnhow to capitalize on the movements benefits, such as opportunities for more citations and away to build a reputation without the need for conventionalmetrics, such as publication inhigh-impact journals.D Some fields have embraced

33、open data more than others. Researchers in psychology, a fieldrocked by findings of irreproducibility in the past few years, have been especially vocalsupporters of the drive for more-open science. A few psychology journals have createdincentives to increase interest in reproducible sciencefor examp

34、le, by affixing an open-databadge to articles that clearly state where data are available. According to socialpsychologist Brian Nosek, executive director of the Center for Open Science, the averagedata-sharing rate for the journal Psychological Science, which uses the badges, increased tenfoldto 38

35、% from 2013 to 2015.E Funders, too, are increasingly adopting an open-data policy. Several strongly encourage, and some require, a date-management plan that makes data available. The US NationalScience Foundation is among these,some philanthropic (慈善的)funders, including theBillMelinda Gates Foundati

36、on in Seattle, Washington, and the Wellcome Trust in London, also mandate open data from their grant recipients.F But many young researchers, especially those who have not been mentored in open science,are uncertain about whether to share or to stay private. Graduate students and postdocs, whooften

37、are working on their lab heads grant, may have no choice if their supervisor or anothersenior colleague opposes sharing.G Some fear that the potential impact of sharing is too high, especially at the early stages ofa career. “Everybody has a scary story about someone getting scooped (被抢先),“ says New

38、 YorkUniversity astronomer David Hogg. Those fears may be a factor in a lingering hesitation toshare data even when publishing in journals that mandate it.H Researchers at small labs or at institutions focused on teaching arguably have the most tolose when sharing hard-won data. “With my institution

39、 and teaching load, I dont havepostdocs and grad students,“ says Terry McGlynn, a tropical biologist at California StateUniversity, Dominguez Hills. “The stakes are higher to share data because its a bigger fractionof whats happening in mylab.“I Researchers also point to the time sink that is involv

40、ed in preparing data for others toview. Once the data and associated materials appear in a repository (存储库 ),answering questionsand handling complaints can take many hours.J The time investment can present other problems. In some cases, says data scientist KarthikRam, it may be difficult for junior

41、researchers to embrace openness when senior colleaguesmany of whom head selection and promotion committeesmight ridicule what they may viewas misplaced energies. “Ive heard this recentlythat embracing the idea of open data andcode makes traditional academics uncomfortable,“ says Ram. “The concern se

42、ems to be thatopen advocates dont spend their time being as productive as possible.“K An open-science stance can also add complexity to a collaboration. Kate Ratliff, whostudies social attitudes at the University of Florida, Gainesville, says that it can seem as if thereare twocamps in a fieldthose

43、who care about open science and those who dont. “Theres anew area to navigateAre you cool with the fact that Ill want to make the data open?whentalking with somebody about an interesting research idea,“ she says.L Despite complications and concerns, the upsides of sharing can be significant. For exa

44、mple, when information is uploaded to a repository, a digital object identifier (DOI) is assigned. Scientists can use a DOI to publish each step of the research life cycle, not just the final paper. In so doing, they can potentially get three citationsone each for the data and software, inaddition t

45、o the paper itself. And although some say that citations for software or data havelittle currency in academia, they can have other benefits.M Many advocates think that transparent data procedures with a date and time stamp willprotect scientists from being scooped. “This is the sweet spot between sh

46、aring and gettingcredit for it, while discouraging plagiarism (剽窃),“ says Ivo Grigorov, a project coordinatorat the National Institute of Aquatic Resources Research Secretariat in Charlottenlund, Denmark. Hogg says that scooping is less of a problem than many think. “The two cases Im familiar withdi

47、dnt involve open data or code,“ he says.N Open science also offers junior researchers the chance to level the playing field by gainingbetter access to crucial date. Ross Mounce, a postdoc studying evolutionary biology at theUniversity of Cambridge, UK, is a vocal champion of open science, partly bec

48、ause his fossil-based research depends on access to others data. He says that more openness in science couldhelp to discourage what some perceive as a common practice of shutting out early-careerscientists requests for data.O Communication also helps for those who worry about jeopardizing a collabor

49、ation, he says. Concerns about open science should be discussed at the outset of a study. “Whenever you starta project with someone, you have to establish a clear understanding of expectations for whoowns the data, at what point they go public and who can do what with them,“ he says.P In the end, sharing data, software and materials with colleagues can help an early-careerresearcher to gain recognitiona crucial component of success. “The
