Would-be graduate students in philosophy may again apply to the University of Colorado at Boulder, to begin their studies in fall 2015. Graduate admissions to the department were suspended last year after an external study of its climate described systemic sexual harassment and bullying. Andy Cowell, who was appointed interim chair of philosophy following the American Philosophical Association subcommittee's unflattering report, said in a statement that department faculty members “had willingly participated in numerous facilitated department workshops, as well as activities and exercises to build the culture" spanning the last nine months. Current graduate students were involved in the reform process. Provost Russell L. Moore called the department's efforts "laudable," saying they could serve as a model for other departments struggling with climate issues.
Google Scholar will be 10 years old as of next month. Also coming up fast, early in the new year, is the 10th anniversary of the launching of Inside Higher Ed. Just to be totally clear about it, they were completely unrelated developments, though I do seem to remember each being met with skepticism and reservations, in some quarters. Certain senior academics insisted on calling them both “blogs.” (It was a simpler time.)
Suffice it to say that the beta days soon passed. The world of higher learning has grown ever more dependent on the internet’s intricate system of tubes -- with the academic web now serving as publishing platform and archive, and also as a point of access to restricted or proprietary digital collections. In principle, at least, we ought to be able to determine the dimensions of the scholarly web: how many items it contains (papers, dissertations, conference recordings, etc.), in however many formats, and with whatever depth of indexing and degree of retrievability. But actually taking the measurements is another matter. They belong to the epistemic category Donald Rumsfeld so aptly dubbed “the known unknowns.”
How about posing a narrower question, then? Just how big is Google Scholar? As with the company’s search-engine algorithms, that information remains a trade secret. But a couple of recent studies have tried to sound the depths of Google Scholar – using GS itself.
The earlier of the papers is “The Number of Scholarly Documents on the Public Web” by Madian Khabsa and C. Lee Giles, published in May by PLOS One, the online open access journal. Lee is a professor of information and computer sciences at Pennsylvania State University, University Park, where Khabsa is a Ph.D. candidate in computer science and engineering.
Their study, conducted in early 2013, started with a pool of 10 papers each from 15 categories used by another search engine, Microsoft Academic Search. The fields covered were agriculture science, arts and humanities, biology, chemistry, computer science, economics and business, engineering, environmental sciences, geosciences, material science, mathematics, medicine, physics, and social sciences, plus multidisciplinary. The researchers then requested from both Google Scholar and Microsoft Academic Search a list of the distinct incoming citations to each paper. That is, if paper X cited a target paper seven times, it counted only as one citation.
“Overall,” Khabsa and Lee report, “we obtained 41,778 citations from MAS and 86,870 citations from Google Scholar,” including all the metadata available: “the document's title, list of authors, number of citations, year of publications, and the venue of publication (if available).”
The format and range of metadata are not standardized, but with some effort the results from the two search engines could be compared to determine how many items appeared in both -- as well as the number GS had but MAS didn’t, and vice versa. The researchers also determined the degree of overlap in each of the 15 fields, and the percentage of papers available without payment or subscription.
At the time of the experiment, MAS claimed 48.7 million records. Taking into account the degree of overlap, the researchers “estimated Google Scholar to have 99.3 million documents, which is approximately, 87% of the total number of scholarly documents found on the web,” which they determine to be some 114 million items in English, with about a quarter of them freely available.
The share of open-access material varies considerably between fields, of course. At the low end is agricultural science, with 12 percent. Computer science is in the lead, with half of scholarly publications being freely available. (The percentages are broken down by field in the paper’s second table.)
In July, Enrique Orduña-Malea and three other researchers in Spain published “About the Size of Google Scholar: Playing the Numbers” through the site arXiv. The paper begins with an assessment of the methodology and findings of Khabsa and Lee. In particular, Orduña-Malea et al. stress “the low indexation of institutional repositories on Google Scholar” and the GS policy of not indexing files over 5MB, “a procedure which is especially critical for doctoral theses).” They suggest that the earlier study probably underestimates the size of the academic web – even of its strictly Anglophone component -- while overestimating how much of it Google Scholar indexes.
The authors go on to describe a battery of tests designed to measure GS “from the inside,” so to speak. Generally this involved performing searches for particular kinds of documents or search terms, using different temporal filters. For example: the search could be made for patents and citations issued in a century, then by decade within that century, and the result compared.
An intriguing variant is what the authors call an “absurd query,” in which the search is for a very common word likely to be found in most documents, with variations on the search parameters, including temporal filters.
The Khabsa-Lee study came up with the estimate that Google Scholar indexed 99.3 million documents in English. Extrapolating from that, with English accounting for 65 percent of GS material, Orduña-Malea et al. determine that the Khabsa-Lee method yields a total Google Scholar database of 152.7 million documents. (Despite their critique, the authors call Khabsa and Lee’s work “novel and brilliant.”)
The methods that Orduña-Malea and his colleagues tried were not restricted to English-language scholarship. Their findings varied from a low of 126.3 million documents in Google Scholar to a high of 176.8 million.
For their part, the Spanish researchers conclude that a judicious estimate would be in the neighborhood of 160 million items. “However,” they write, “the fact that all methods show great inconsistencies, limitations and uncertainties, makes us wonder why Google does not simply provide this information to the scientific community if the company really knows this figure.”
It’s a fair point, and one the company should answer. Its 10th anniversary might be a good time for Google Scholar to give its users the gift of transparency.
The American Association of University Professors Foundation is granting $5,000 in temporary financial aid to Steven Salaita, via its Academic Freedom Fund. The controversial scholar, who is currently jobless, is contesting the revocation of his tenured faculty appointment to the American Indian studies program at the University of Illinois at Urbana-Champaign. The institution pulled Salaita's offer this summer due to his anti-Israel remarks on Twitter, which many have called uncivil and unbecoming of an academic. Still, many of those who object to Salaita's tweets say they are protected speech and should not have cost him his appointment.
Both the foundation's governing board and the greater AAUP say that Salaita wasn't fired or "unhired," but rather "barred from teaching" the classes he already had been assigned to teach this semester. AAUP maintains this kind of "suspension" should be paid. The University of Illinois Board of Trustees formally rejected Salaita's professor candidacy last month, indicating he does not have a job there.
A faculty committee at the university is looking into the circumstances surrounding Salaita's retracted offer. A spokeswoman for Salaita's legal team at the Center for Constitutional Rights said he is preparing to file a lawsuit.
In his "Civility Manifesto" published here last week Cary Nelson cites my blog post, "Is Incivility the New Communism?," as "particularly hyperbolic" in its critique of efforts by some university administrators to demand that free speech be limited to expression they deem "civil." In his own expression Nelson himself has been known to employ hyperbole -- as well as sarcasm -- even to the point that some might call uncivil, so it's surprising he does not recognize that my exaggeration was intentional. Of course, we are not living through a new Red Scare on campus. But the point is that we could be if the incivility monitors have their way.
Nelson asks, "does unrestrained antagonism make for the best learning environment?" It surely does not. But that isn't the issue. No reasonable person welcomes hatred, harassment, or violence. According to Nelson, "Eloquence in the service of conviction does not require abusive rhetoric or personal accusation." But, like it or not, free speech does not require eloquence. It's one thing to encourage civil conduct and reasoned discourse, quite another to regulate expression in the name of such encouragement. But that is precisely what too many college and university administrators and trustees are threatening to do. The threat to free speech rights is real.
But we needn't go further than Nelson's own campus for the most chilling example of an effort to invoke civility as a criterion of free expression. According to University of Illinois at Urbana-Champaign Chancellor Phyllis Wise, “What we cannot and will not tolerate at the University of Illinois are personal and disrespectful words or actions that demean and abuse either viewpoints themselves or those who express them.” This extraordinary dictate goes well beyond encouraging civil communication. Under Wise's disturbing standard a biologist who "demeans" creationism could be out of a job; indeed, the evolutionary viewpoint itself, which creationists claim demeans humanity, could be banned.
While Dirks later clarified his ill-considered statement, Wise has not. Indeed, the Illinois Board of Trustees quickly declared its "collective and unwavering support of Chancellor Wise and her philosophy of academic freedom and free speech tempered in respect for human rights.” According to the board, UI must be a “university community that values civility as much as scholarship.” We know who should assess scholarship: the scholars. But who will judge what is civil? That is precisely the issue.
Nelson is correct that much of the uproar over civility stems from the Palestinian/Israeli dispute and I share his concern about the corrosive effect of that seemingly intractable conflict on both the campus climate and academic freedom. We differ sharply, however, about who is responsible. According to Nelson, only one side is to blame: "verbal excess, aggression, and ad hominem attacks are part of the standard repertoire of the Boycott, Sanctions, and Divestment movement. That typically stimulates raised tempers and sometimes similar behavior on the pro-Israeli side."
But the situation is more complicated. Elements on both sides invoke the protections of academic freedom and the First Amendment when it benefits them and violate these when it doesn't. What about efforts by some supporters of Israel to effectively blacklist faculty members whose views on Middle East studies do not comport with theirs? This move is truly evocative of the Red Scare and more threatening to academic freedom and the independence of the universities than a few "uncivil" words from pro-Palestinian students.
More important, the two sides are not in equivalent positions. Although support for the Palestinian cause is greater on American campuses than in society in general, those who control the universities -- administrators and trustees as well as powerful donors -- are most likely to support the Israeli cause. The expressive weapons of those in power and those without power almost always differ. It is usually the powerless whose voices must be shrill, who may break rules to be heard, who, in short, may be uncivil. Civility, however, can be a privilege of the powerful, whose control over institutions often leads them to silence opponents instead of engaging them. As Greg Lukianoff of the Foundation for Individual Rights in Education noted, in his experience "campus administrators are most likely to deem as 'uncivil' speech that criticizes them or the university’s sacred cows."
This imbalance is illustrated by events at Ohio University, which Nelson cites as an example of "uncivil" expression escalating to arrests. Nelson ignores, however, what preceded these arrests. A student government leader filmed a video in which she poured fake blood over herself to protest Israeli actions in Gaza. The video was bold and even graphic, but under the law it is protected speech and as a video abused or threatened no one. The student, however, received numerous death threats. How did the university president respond? In a mealy-mouthed statement he disassociated the university from the video and called vaguely for civility, but remained silent about the death threats, effectively coming down on one side of the controversy. Only later were four pro-Israeli students arrested for disrupting a meeting, which suggests that lame public calls for civility are also largely ineffective.
"When administrators urge us to be models of civility they are doing exactly what their job requires," Nelson declares. I agree, but the danger to which I and so many others have been responding is that such urgings show undeniable and dangerous signs of becoming requirements. And such requirements may threaten academic freedom and free speech as much as any loyalty oath.
