T

17、he finding suggests that anti-inflammatory drugs could help to combat or prevent cancer. “Lifelong, if you take a small quantity of something that 1 inflammation (炎症), such as aspirin, it could reduce the risk of cancer,“ says Adam Hurlstone of the University of Manchester, UK. When tissue is wounde

White blood cells called leukocytes (白血球) are among the first cells to react to this 2 , homing in to kill the infectious agent, clean up the mess and rebuild 2 tissue. At first, the tissue becomes inflamed, but this subsides as the wound is cleared and r

Hurlstone and his colleagues 4 engineered zebra fish so that skin cells and leukocytes would show different 5 under ultraviolet light. Some zebra fish were also engineered t

Students rarely ask librarians for help, even when they need it. This is one of the sobering (令人警醒的) truths the librari

23、ans have learned over the course of a two-year, five-campus ethnographic (人种学的) study examining how students view and use their campus libraries. The idea of a librarian as an academic expert who is available to talk about assignments and hold their hands through the research process is, in fact, fo

24、reign to most students. Those who even have the word “librarian“ in their vocabularies often think library staff are only good for pointing to different sections of the stacks. B. The ERIAL (Ethnographic Research in Illinois Academic Libraries) project contains a series of studies conducted at Illin

25、ois Wesleyan, DePaul University, and Northeastern Illinois University, and the University of Illinois“s Chicago and Springfield campuses. Instead of relying on surveys, the libraries included two anthropologists (人类学家), along with their own staff members, to collect data using open-ended interviews

26、and direct observation, among other methods. The goal was to generate data that, rather than being statistically significant yet shallow, would provide deep, subjective accounts of what students, librarians and professors think of the library and each other at those five institutions. C. The most al

27、arming finding in the ERIAL studies was perhaps the most predictable: when it comes to finding and evaluating sources in the Internet age, students are extremely Internet-dependent. Only 7 out of 30 students whom anthropologists observed at Illinois Wesleyan “conducted what a librarian might conside

28、r a reasonably well-executed search,“ wrote Duke and Andrew Asher, an anthropology professor at Bucknell University, who led the project. D. Throughout the interviews, students mentioned Google 115 timesmore than twice as many times as any other database. The prevalence of Google in student research

29、 is well-documented, but the Illinois researchers found something they did not expect: students were not very good at using Google. They were basically clueless about the logic underlying how the search engine organizes and displays its results. Consequently, the students did not know how to build a

30、 search that would return good sources. “I think it really exploded this myth of the “digital native“,“ Asher said. “Just because you“ve grown up searching things in Google doesn“t mean you know how to use Google as a good research tool.“ E. Even when students turned to more scholarly resources, it

31、did not necessarily solve the problem. Many seemed confused about where in the constellation (云集) of library databases they should turn to locate sources for their particular research topic: Half wound up misusing databases a librarian “would most likely never recommend for their topic.“ For example

32、, “Students regularly used JSTOR, the second-most frequently mentioned database in student interviews, to try to find current research on a topic, not realizing that JSTOR does not provide access to the most recently published articles.“ Unsurprisingly, students using this method got either too many

33、 search results or too few. Frequently, students would be so discouraged that they would change their research topic to something that requires a simple search. F. “Many students described experiences of anxiety and confusion when looking for resourcesan observation that seems to be widespread among

34、 students at the five institutions involved in this study,“ Duke and Asher wrote. There was just one problem, Duke and Asher noted: “Students showed an almost complete lack of interest in seeking assistance from librarians during the search process.“ Of all the students they observedmany of whom str

35、uggled to find good sources, to the point of despairnot one asked a librarian for help. G. In a separate study of students at DePaul, Illinois-Chicago, and Northeastern Illinois, other ERIAL researchers deduced several possible reasons for this. The most basic was that students were just as unaware

36、of the extent of their own information illiteracy as everyone else. Some others overestimated their ability or knowledge. Another possible reason was that students seek help from sources they know and trust, and they do not know librarians. Many do not even know what the librarians are there for. Ot

37、her students imagined librarians to have more research-oriented knowledge of the library but still thought of them as glorified ushers. H. However, the researchers did not place the blame solely on students. Librarians and professors are also partially to blame for the gulf that has opened between s

38、tudents and the library employees who are supposed to help them, the ERIAL researchers say. Instead of librarians, whose relationship to any given student is typically ill-defined, students seeking help often turn to a more logical source: the person who gave them the assignmentand who, ultimately,

39、will be grading their work. Because librarians hold little sway with students, they can do only so much to reshape students“ habits. They need professors“ help. Unfortunately, faculty may have low expectations for librarians, and consequently students may not be connected to librarians or see why wo

40、rking with librarians may be helpful. On the other hand, librarians tend to overestimate the research skills of some of their students, which can result in interactions that leave students feeling intimidated and alienated (疏远的). Some professors make similar assumptions, and fail to require that the

41、ir students visit with a librarian before carrying on research projects. And both professors and librarians are liable to project an idealistic view of the research process onto students who often are not willing or able to fulfill it. I. By financial necessity, many of today“s students have limited

42、 time to devote to their research. Showing students the pool and then shoving them into the deep end is more likely to foster despair than self-reliance. Now more than ever, academic librarians should seek to “save time for the reader“. Before they can do that, of course, they will have to actually

43、get students to ask for help. “That means understanding why students are not asking for help and knowing what kind of help they need,“ say the librarians. J. “This study has changed, profoundly, how I see my role at the university and my understanding of who our students are,“ says Lynda Duke, an ac

44、ademic librarian at Illinois Wesleyan. “It“s been life-changing, truly.“（分数：71.00）(1).None of the students observed in the ERIAL project asked a librarian for help when searching sources, even when they were in despair.（分数：7.10）(2).The librarians learned from a two-year, five-campus ethnographic stu

Give you

49、r team-mate or colleague a pat on the back after a setback, and the chances are you“re not consciously seeking to change the mix of signalling chemicals in their brain. It may not seem like it, but these socially important rituals and others like them predate the time our species first walked the African continent. Human behaviours that involve physical social contact have a lot more in common with social grooming activities we typically associate with other species than we might initially think
