Why Steve Strauss should stop hiring English majors and hire some scientists instead

Recently, a few people I know shared this column on Facebook. Written by Steve Strauss, a lawyer/author and self-described "small business expert", the short piece from the Huffington Post makes the case that English majors are pretty much the bee's knees. Strauss prefers to hire English majors for a variety of roles, as he explains:
I love English majors. I love how smart they are. I love their intellectual curiosity. And I love their bold choice for a major. Most of all, I love to hire them. 
A recent article by the great David Brooks in the New York Times about the changing nature of the Humanities in higher education just reinforced why, when given my druthers, English majors are my employee of choice. 
And the reason is not that I am a writer; I more consider myself an entrepreneur than anything else. I run a small business and the people I hire do a variety of tasks -- SEO, project management, social media, and so forth. 
For my money (literally and figuratively), for my needs, and I suggest the needs of most small businesses, English majors are easily the top choice when it comes to getting the type of teammate who can make us all better, as they say in basketball.
Strauss goes on specify some key traits apparently endemic to the English major population. These are: (1) English majors are smart and creative independent thinkers, more so than business majors; (2) English majors are bolder risk-takers than others; (3) English majors are always better writers; and (4) English majors are easy to work with.

I suspect many scientists will disagree. I take issue with the broadness of Strauss's assertions--though he never claims to have broadly surveyed skillsets of humanities scholars, his descriptors read like mere feel-good fluff. Yes, there are English majors who have those characteristics, and many English majors are successful. But "rigor" and "difficult assignments" are not essential traits of the undergraduate English experience.  While English may allow deep thinking, it doesn't absolutely require it, and it's certainly easier to skate through an English degree than, say, one in chemical physics or organic chemistry.

You see more chemists who also know literature than you see literary analysts who know molecular orbital theory. But isn't that just because science is more specialized? Well, yes and no. Individual fields of science certainly have their own jargon, methodology, and bodies of knowledge. But the scientific process is fairly universal, and you see people switch fields in their BS/PhD and PhD/postdoc transitions.

That all sounds harsh, of course, and borders on the increasingly-prevalent-but-misguided attitude of "cut the humanities, boost only employable fields". So to clarify: I like the humanities. I really do. I've always enjoyed literature and music (both production and consumption), and I think their study is vital for making a person more culturally aware and well-rounded. I have opinions on writers and composers. I was one of those people who didn't whine about general-education requirements interfering with "real" coursework. But assigning top general employability status to English majors overlooks a key group of students who, when successful, possess all the abovementioned skills and more: science majors.

The case for hiring science majors

As previously mentioned, Strauss touted the creativity of English majors and their ability to think analytically. Creativity is essential to good science as well; skilled researchers tend to be creative people who see alternate ways to solve problems. Moreover, scientists find solutions that work, based on reality and reproducibility. This clarification is important, because "analysis" means very different things in scientific and non-scientific circles. However, scientists are quite good at two things: (1) finding information; and (2) evaluating information.

Strauss also claims English majors are superior risk-takers. But scientists are too. They have to be. Good research is always at the edge of knowledge--which means it might not work. Bench time might be wasted. A six-year PhD might produce no results and lead to no job. Ideas might get defunded and banished to obscurity. Going to grad school is a tremendous risk. So is working for an untenured professor, or starting a brand-new project. So the advantage here again goes to scientists. Additionally, scientific risk-taking is grounded in reality--helpful for businesses.

What other employable traits do scientists tend to have? Work ethic: long hours are the norm and determination over long periods of time (ca. 5 years) is required. Versatility: the scientific method is employable between variant research areas but also to management and business decisions. Technical skills: this probably goes without saying, but intimate knowledge of scientific theory and technique isn't easily gleaned from Google. Even in non-bench roles, this can be quite important. Teamwork: whereas writing English papers is a solitary venture, lab research is done in groups, and collaboration between students and labs on the experiment or project scale is commonplace. Objectivity: whereas the humanities stress the voice and identity of the individual (subjectivity), science emphasizes minimization of bias. This is useful in risk assessment, evaluation, project design, etc.

All in all, I think science majors sound pretty employable.

What we can learn from our English-wrangling colleagues

The claim about English majors being superior writers is also worth examining. Do English majors write? Yes. Do they write a lot? Most of them. Do they write well? The good ones write academic papers well, but an increased vocabulary and flowery verbiage doesn't mean good communication. Of course, many English majors are good communicators, but the degree doesn't guarantee that. And not having an English degree doesn't mean you can't write just as well as someone who has one.

It's worth noting that significant differences exist between scientific/technical and academic (non-scientific) writing. In another life, I worked closely with undergraduate writing tutors. Most were English majors, and as a lot they were very intelligent. But all of them were horrid at actually helping science students improve their communication skills. The result was a continuous stream of frustrated chemistry students with half-mangled lab reports. The writing process is fundamentally different across the humanities/science divide, which makes me skeptical that the garden-variety English major would be good at writing in a technical or scientific context (where content is highly specific, highly technical, and verbal economy is vital). Some are good at it, but it's not because of Chaucer.

That being said, scientists themselves are very commonly awful writers. Those who deny this or think it's not important are simply either ignorant or delusional. Then again, scientists are perhaps more likely to be blunt and direct, which has its appeal. Regardless, it's probably good for budding scientists to take all the writing experience they can get and to pay attention not only to the facts of what they write but the organization and presentation. Clear communication makes ideas easier to sell, cuts down on wasted time, and improves work efficiency. The ability to write well (more than just JACS communications) can be a huge selling-point when building an employment skillset, as it extends to grants, business proposals, technical reports, and intellectual property claims.

A final anecdote.

A friend of mine switched from pre-med to business during undergrad and found himself in a business database systems class. The class entailed a team-based project wherein each group of students needed to create a database system for a local business. Several of the born-and-bred business majors insisted that the class was probably the most difficult in the university. Having taken two years of pre-med coursework, my friend pointed out the difficulty and rigor in the hard sciences, especially in independent research. Oh, no way, the business majors insisted, scientific research is just following recipes.

The piece is short, so it's worth reading.  Do also peruse the comment section, which is rife with people praising Strauss's words and/or correcting each others' grammar/diction.

Chemical Fun from 1921

What's more fun than historical documents? Historical chemistry documents! From one such document: the following tongue-in-cheek paragraph appeared in the April edition of the briefly-published and mostly-otherwise-serious quarterly departmental (U of I) magazine The Illinois Chemist 1921, 5(3), 12.


The text (written out):

CHEMICAL FUN. Procedure (to be followed with extreme carelessness): Select several choice cut medium sized hydrogen ions from a bottle and scour until thoroughly clean. Wipe and dry carefully. Avoid handling. Lay aside. Now soak a few large chunks of metallic sodium in a beaker of distilled water and allow to stand quietly. In the meantime be collecting a pailful of cathode rays. Filter these, using suction. Beat them to a froth with two and three-quarters pounds of green radium (the red variety is highly unsuitable for this experiment). Now stir in the hydrogen ions, one at a time. Drain the sodium and put it in above mixture. Grind up with T. N. T. and put in a mortar and add all at once. Thus the mixture will become catalyzed. -- Voodoo, M. I. T.

Chemical fun, indeed. Sounds like a job for Blog Syn!

JACS comment section? Back to the future

It's been a very interesting couple of weeks in the realm of Blog Syn (the beginning of Blog Syn #003A has a roundup for anyone who hasn't been following). People across a number of blogs have noted the importance (or at the very least, usefulness) of chemists participating in social media and rapid web communication (indeed, even Phil Baran's lab has started a blog, despite hegemonic bias against blogging in the field of organic synthesis). 

How can chemists use social media to the greater benefit? Take, for instance, the first comment in Chemjobber's reply to the IBX+water conclusion. Polychem says (bold emphasis mine):
This work makes me think that every paper published on pubs.acs.org deserves its own comment section. I can imagine it being abused, but there may be some good insights by having essentially a wider peer review where you don't have to pay to print your rebuttal.
Good job Blog Syn people!
 Hmm... a comment section at JACS? Check out this 1996 editorial from the journal! For those stuck outside the paywall, an excerpt:
There is no question that digital computers have had a large impact on the publication of scientific research. JACS uses computers in the management of the journal data base and in production of the journal. Most manuscripts are now submitted in final form as floppy disks, and e-mail is often used for correspondence with authors and reviewers. Recently, especially with the wide accessibility and usage of the World Wide Web (WWW), interest has turned to electronic publishing, i.e., to the posting of manuscripts on the web rather than, or in addition to, producing a hard copy (print) journal. The advantages of electronic publishing include the faster appearance of a paper at a presumed lower cost than printing (with the attendant possibility of wider distribution) as well as the ability to provide materials, like computer programs, movies, color figures, and large amounts of experimental data, not available in the hard copy. Concerns about electronic publishing include the maintenance of the quality and integrity of the published literature, providing for the long-term archiving of papers, and assuring that financial support is available to carry out the needed peer review and maintenance of the archive. These points are discussed in a booklet available from ACS Publications: Will Science Publishing Perish?
Interesting that the ACS proposed lower cost and wider distribution--I wonder if that worked out that way? The last section of the editorial is also a fun read:
JACS Web Page -- An Experiment. The JACS web page (accessible via the ACS publications page at http://pubs.acs.org) displays instructions for authors, links to supporting information, and the table of contents for the latest issue of the journal. As an experiment we will also try out a section for selected correspondence and comments. Readers can submit, by way of a form available on the web page, scientific comments pertaining to recently published JACS papers. Authors will be asked to reply. Posting of comments will not be automatic. Comments for posting will be selected by the editors and they will not be sent out for review. There will be no appeals for comments not selected. Comments will not be published in hard copy or CD versions of the journal nor will they be archived. We hope these comments will generate interesting discussions and help amplify and clarify ideas and results published in JACS papers. They are not meant to discuss priorities or present still unpublished ideas or results. Additions and corrections will still be published in the printed version of JACS. We hope the level of discussion on the JACS page will be significantly higher than the average WWW newsgroup! This experiment will be terminated if the community feels it is not useful (or if it becomes too burdensome for the editors). At this time we cannot accept manuscripts submitted electronically for review; however, we are investigating the possibility of doing this in the future. As stated at the outset, the science publication field is evolving rapidly. The new possibilities are intriguing, but the community will best be served by an orderly evolution that involves the best features of both the print and electronic media.
It's quite revealing to see the difference between scientific publishing just 17 years ago (oh wow, 1996 was 17 years ago??) and now--after all, electronic submission is de rigueur not only for SI but for main text and for correspondence with reviewers.

More interesting, though: there was a comment section on JACS before the journal even started putting the manuscripts themselves online. Seems like unusually progressive thinking by the ACS!

But if you go to the JACS website now, there's no comment section. What happened to it? A search of editorials from the journal gives no relevant hits and a 2002 editorial discussing other web-based aspects of JACS makes no mention of it. Did it die a quick, fiery death?

Indeed, there's a lot of room for publishers to include the community in scientific discourse. Some do a little: Nature Chemistry, for instance, has a good metrics section that indexes blogs (but no comment section). The ACS journals don't have comments, nor do Taylor & Francis, the RSC journals, Elsevier, or PNAS.

Does anyone do comments?

Yes! Take a look at PLoS One (example article): they have comment section built in to a very slick web interface.

It'll be interesting to see how the face of scientific communication changes over the next few years.

Communication of science


Peer review and publication

  • Neuroskeptic writes about the perhaps-sensical, perhaps-counterintuitive situation of stats quality in journals. It seems that high-impact journals (e.g. Science and especially Nature) are more likely than many low-impact journals to have insufficient statistical analysis. This may not be surprising, given the incentive for those journals to publish hyped-up work. Is there a similar trend in chemistry? I suspect that many medium-tier journals provide more solid experimental characterization and writeup than some of the flashier ones.
  • Scientists unsatisfied with the status quo of journal publishing practices will find this development interesting. Biologist Michael Eisen has declared that he will publicly post each paper from his lab prior to journal submission for pre-publication, community-oriented peer review. It's a refreshing idea--hopefully others will follow suit.
  • Derek Lowe points to the disappearance of the electronic-only open-access publication Journal of Advances in Developmental Research. Although he notes the relative unimportance of that particular journal, he brings up some points that open-access advocates should pay close attention to: predatory publishing and digital preservation. On a related note, Kevin Bonham writes about the premiere of a new prominent online-only journal, PeerJ.
  • The story of the recent Xi Yan plagariasm endeavor (and the journal's lackluster, non-punitive response) has been written about with proper consternation by See Arr Oh. This kind of case is amazing, as it's the kind of thing routinely warned against in undergraduate writing courses and in orientation lectures at grad programs. Despite this, the plagiarists quite often win (for another plagiarist who 'won', check out Jonah Lehrer). For those with a spare half-hour, check out the Chemjobber/See Arr Oh podcast about plagiarism and peer review. Also, the comments section at the relevant In the Pipeline posting contains a discussion of the ethics of paper submission and whose fault plagiarism is (one commenter seems to think it lies with editors/reviewers and not  professors).
  • In the last two weeks, two more entries came out at Blog Syn (a Pd-catalyzed site-selective C-H olefination and an IBX-mediated benzylic oxidation). Give them a read--and submit your comments if you have suggestions or questions! Blog Syn is supposed to be a discussion-oriented endeavor (and the further updated to Blog Syn #003 illustrate that, I think). On another note, despite broad support (including from more than one big-name prof), Blog Syn does have its critics. See particularly the comments section at In The Pipeline, which is brimming with vitriol (so much that Derek Lowe jumped in to defend Blog Syn).
  • Science librarian Bonnie Swoger discusses common metrics of scientific publishing, such as h-index and impact factor, citing the importance of context in any comparisons.

Stop using that word: Facile

Certain words tend to catch on in the scientific literature, such as "novel", which increased exponentially in usage starting in the 1980s. One of those catchy words is one that I previously* used like candy: facile.

Chemists like to describe reactions as "facile." By that, they usually mean easily-performed, smooth, or simple. You know, not much fuss involved. And indeed, that's one of the definitions (from the OED):
adj. (1) a. That can be achieved with little effort; straightforward, easy. In later used freq. in disparaging sense: contemptibly easy. b. Of instructions, a device, etc.: easy to understand or make use of; simple. c. Of a course of action, a method, etc.: presenting few difficulties.
That is the original, historical meaning. Another (more modern) definition carries a different implication (from the Oxford Pocket Dictionary):
adj. (1) ignoring the true complexities of an issue; superficial; or (2) (of a person) having a superficial or simplistic knowledge or approach
And if you type "facile" into Google, you get this immediately:
adj. (esp. of a theory or argument) Appearing neat and comprehensive only by ignoring the true complexities of an issue; superficial
Essentially, "facile" in modern usage (last century or so) has a negative connotation. And take a look at the synonyms for facile (Oxford again):
simplistic, superficial, oversimple, oversimplified, schematic, black and white; shallow, pat, glib, slick, jejune, naive
It's interesting to note that wiktionary has a chemistry-specific entry for "facile":
(chemistry) Of a reaction or other process, taking place readily.
Of course, language is defined by usage, so maybe I'm being picky here. But why not describe procedures as "straightforward", "robust", "easily performed", or any number of other, less ambiguous descriptors? (My intuition says those terms sound too common/"blue-collar" to many academics)

When did "facile" catch on? Well, from a crude PubMed search, it looks like the late 1990s was the tipping point (incidentally, PubMed makes it way easier than SciFinder to get data on this kind of thing. Sorry, CAS). Additionally, most of these references are (not surprisingly) from synthetic organic chemistry papers. See also this description of the two meanings of the word and their historical context.

The shrouded meaning of facile adds overlooked complication when authors start to invent words (after all, organic chemists are wont to derivatize things). There's a handful of examples from the literature that use "nonfacile" (which isn't even a word; go ahead, check the OED or Merriam-Webster).

Take this example from an otherwise-good trifluoroborate-preparation paper (Lennox, A.J.J., Lloyd-Jones, G.C. Angew. Chem. Int. Ed. 2012, 51(37), 9385-9388. doi: 10.1002/anie.201203930):
Replacing MeOH with diethyl ether led to co-precipitation of 2a with other potassium salts (KF/RCO2K etc.), thus making isolation of pure 2a nonfacile. Switching to MeCN kept trifluoroborate 2a in solution, but an excess of carboxylic acid (e.g. acetic or ortho-iodobenzoic acid) was still required (Scheme 2).
So if "facile" means "contemptibly easy" or "appearing neat and comprehensive only by ignoring the true complexities of an issue", what does "nonfacile" mean? Was isolation of 2a not contemptibly easy (just acceptably easy?). Did isolation merely appear difficult while really, under the surface, it was simple?

Stop using that word.

* i.e. before a reviewer pointed out the proper definition.

Reading assignments, vol. 9


This week's stuff is pretty heavily communication-themed; a lot of that is going around with the ScienceOnline 2013 deal having gone down. Anywhere, here's some general science enjoyment:

Chemophobia

  • Chemophobia has been a major topic of the social-media-dom recently due to the ScienceOnline 2013 conference. In particular, Saturday marked the chemophobia-specific portion of the conference (Session 8A), which included a contemporaneous Twitter discussion via the hashtag #chemophobia. For those who had to work this Saturday (woo, columns, woo) the session notes have been posted online, and there's a quite impressive wiki entry containing an abundance of relevant and interesting chemophobia-related links and discussions.
  • Michelle at The Culture of Chemistry has a thoughtful analysis of a recent chemophobia-rife New York Times story; she points to language and how it affects perception of concepts.
  • Paul at ChemBark shares his tips and proposed strategies for how to combat chemophobia. It's a good read that sums up the origins and dangers of chemophobia pretty well. The recommendations are good, too: ACS should be doing its part (come on, guys!) but graduate students and faculty need to take it upon themselves to do outreach, regardless of the perceived waste of time. (That being said, the hostile intellectual atmosphere and the rough job market make spending any time on outreach seem unappealing to those trying to get as many ninth-author Tet. Lett. papers as possible published before graduating).
  • Don't miss this latest Chemjobber podcast, wherein he discusses chemophobia and chemical communication with freelance writer/chemist Rebecca Guenard. 

Science communication

  • See Arr Oh pokes fun at general features of chemistry blog entries.
  • I found this guest post by Frank Swain both insightful and heartening. He writes of his UK-based BenchPress Project, which seeks, among other things, to have volunteer scientists give guest lectures to journalism students. The goal is to increase science and math (maths) literacy among journalists. I think it's a pretty important effort; even if scientists themselves try to do outreach and writing, journalists have the broadest audience and the means to reach them. Changes in science communication have to come from within both sectors!
  • David Rubenson argues that despite a growing need for science communication, the quality of science communication has been in decline. He points to several symptoms (e.g. cluttered slides) and causative agents (e.g. overstretched researchers). I found significant his reference to two Nobelists who published infrequently (also, it reminded me of Daniel Day-Lewis).
  • Always-interesting and often-controversial, Keith Kloor discusses the relative importance of general science literacy and news literacy. He argues for the importance of the latter (while not neglecting the former); in particular, he calls for news literacy to have a place in education. It shouldn't be an unfamiliar concept to scientists, who (should) be experienced at evaluating credibility of sources.
  • UIUC anthropologist and science blogger Kate Clancy has an interesting piece (relevant to anyone who uses social media, especially those who write) about the pros and cons of filling out your online presence with your real identity.

Pseudoscience and denialism

Reading assignments, vol. 8

Links and interesting topical stories from the week follow below.

Academia

  • Scientific and writer DNLee of Scientific American gives a powerful account of the factors denying good STEM education to many students (namely, those of low socioeconomic status). It's a very important read, as it highlights many issues in science education (and education and science culture in general) that very often get ignored. 
  • At Gene Expression, Razib Khan comments on affirmative action and science. He's largely dismissive of it, saying science doesn't need cultural diversity per se (with a caveat that such diversity is valuable from a social perspective). It's a worthwhile read; only the myopic would be reluctant to admit there is a rather skewed demographic makeup in science relative to the entire population.
  • Derek Lowe has a commentary on an ACS Med. Chem. Lett. opinion piece regarding the role of academia in drug discovery. It's worth thinking about, especially to those interested in science funding or science policy. The case can really strongly be made that academia can not replace pharma as a productive drug production vehicle, but the decoupling from financial risk means academic labs can push innovations that are potentially high impact but not necessarily profitable.

Scientific representation and misrepresentation

Chemistry job market

  • Glen Ernst comments on a 1979 article from C&EN bemoaning an impending surplus of chemistry PhDs exceeding the number of available jobs. As Glen points out, "non-traditional" here meant not being a university professor. Today, the scope of "traditional" careers has broadened, but the employment outlook seems bleaker. Still, it's an interesting insight from the late 70s.
  • I found this interview of ChemDraw wizard (and recently-hired Perkin Elmer employee) Pierre Morieux by Chemjobber quite interesting. It's a neat career path, and a cool story of how social media and online networking can land you a job. At the same time, comments imply that some chemists think it is overkill (and perhaps a telltale sign of the job market) that a long PhD and a competitive postdoc do not result in a "traditional" job. (I'd caution that non-"traditional" careers aren't  necessarily fallbacks and can be more rewarding than the big-name jobs; I'd also like to point out that many people in many professions change career paths many times!). 
  • At Chemistry World, economist Paula Stephan has some perhaps-controversial, perhaps-obvious (depending who you ask) points on the PhD glut. She likens grad school to a pyramid scheme, where the focus of grad school has shifted from producing quality scientists to producing PI-promoting research. She has a series of thoughtful recommendations for improving graduate education. Derek Lowe notes the article and comments on the proposal to increase permanent lab staff (i.e. how to fund it?).
  • Chemjobber has some commentary and depressing statistics on the job market and unemployment rate for chemists (spoiler: it's worse than the average rate for bachelor's degree holders).
  • Don't miss See Arr Oh and Chemjobber's podcast on amusing interview stories.

Plagiarism and the role of publishers

Anyone who reads Just Like Cooking or Chemjobber is by now probably aware of the freshly-discovered plagiarism case wherein a 2013 Chem. Eur. J. article by Professor Xi Yan lifts, verbatim or nearly so, entire portions of a three-years-prior (2009) JACS paper by Professor Valérie Pierre. Reading the commentary, the plagiarism is pretty egregious. Additionally, comments and a further blog post by See Arr Oh have brought up more instances of plagiarism like this.

Of course, #spacedino is immediately brought to mind (for the uninitiated, that particular hashtag refers to the 2012 controversy where esteemed chemist Breslow, of Columbia University, was found to have submitted what amounted to essentially the same publication to multiple journals; it was only really caught because biologists took his lame ending joke seriously). After lengthy conversation on various media and social media outlets, the offending papers were retracted at Breslow's (and others') request (though initially he denied wrongdoing).

While the Breslow violation was aggravating and arguably wrong, the Yan violation is worse. I don't think that's a very controversial point to make, but it's an important one to recognize. The Breslow affair fell into what some categorized as an ethical grey zone; the Yan violation is in clear things-they-tell-you-from-day-one-in-university territory.

Rapid retraction is vital, I'd wager; thought many retracted papers still get heavily cited or believed, early correction is probably the best way to prevent such propagation. Once an article has been believed as true for a substantial period of time and gets included in dissertation of paper-introduction citation-vomits, less care is taken to check the original source and see the glaring retraction notice. Better to stop the train before it leaves the station.

I think this highlights the role of open and quick dialogue among scientists, along the same lines as Blog Syn. The ability to rapidly disseminate these issues when they are discovered can, ultimately, improve the quality of scientific communication. In a pre-social-media era, it was certainly easier to just assume a paper would slip by unnoticed. Not so much anymore; via Twitter, for instance, a wide audience can be quickly reached. See Arr Oh wrote that he has notified the two publishers (Wiley and ACS); it will be very interesting to see what action occurs.

Of course, a point could be made that such post-publication watchdog action shouldn't be necessary. Aren't these things peer reviewed? Alas, I think anyone with a healthy dose of realism is aware that a good bulk of reviewers put in the minimum conceivable effort in reviewing (consider the sheer quantity of bad Supplementary Information files). Usually, this is justified by a variety of factors, namely that reviewers are (1) busy and (2) unpaid. (And they aren't held accountable if the article is later retracted).

But hey, you know who are paid? Publisher staff. I'm a bit surprised that more journal editors haven't made a practice of submitting manuscripts to plagiarism detection software. There's many available; universities often have TAs use them to check undergraduate papers. One comment on Chemjobber's blog points out that Elsevier provides access to one such service, iThenticate, to its reviewers. One readily available service, eTBLAST, compares blocks of text to databases of scientific papers using the BLAST algorithms commonly employed in bioinformatics for sequence alignment. In short, many tools exist for plagiarism detection. So what's the deal, journals? A common claim of open-access opponents is that paywall publishers "add value" to papers by the publication process.

So why aren't all papers routinely submitted to these checks after peer review and before publication? Ideally, reviewers should do a thorough job vetting submitted articles and should be supplied with tools to do so. But publishers share that responsibility. If you can Cantrill an article, it shouldn't slip by.

(One caveat: I'm not sure about the journal coverage of many of the anti-plagiarism packages. eTBLAST, for instance, appears to have access to Medline and PMC, but doesn't seem to have many of the synthetic journals in full-text. That's from an initial assessment; I may be wrong. CrossCheck, the service powered by iThenticate, has a very wide list of included content, but interestingly, I don't immediately see ACS on the list). Is it possible that some of these illustrated issues just don't get picked up by the software?

Lastly, something that would be very interesting: how much scientific plagiarism occurred in the pre-software-detection era? That is, how prevalent were issues of plagiarism in the 1960s? If one took journals from the 1960s, for instance, and ran them through this software--what would they find? Is it more prevalent now? Is it less prevalent? When did scientific plagiarism mature? I suspect the issue is a very old one.

Reading assignments, vol. 7

No weekly link roundup last week due to the #GradMentalHealth discussion, but they resume below. Some pretty interesting stuff!

Perception of science


Science writing

Research highlights

  • From Quintus at Chemistry-Blog comes an account of a synthetic analogue of the ribosome. The authors (see publication in Science) used the technique to produce milligram quantities of a peptide! This was also covered in C&EN and by See Arr Oh.
  • Derek Lowe gives a thoughtful perspective on an article summarizing the state of the field of "virtual screening". Worth a read for anyone interested in med-chem.
  • I'm not usually a fan of reading about or listening to total syntheses, but B.R.S.M. gives a pleasant account of Shair's total synthesis of (+)-hyperforin.
  • Bacterial toxins are interesting things! Check out this write-up on a PLoS Pathogens paper on toxins produced by C. difficile (nasty secondary infection common to those taking heavy loads of antibiotics). Warning to the it's-not-interesting-unless-I-can-column-it-and-solve-the-NMR-spectrum folks: the toxins in question (TcdA and TcdB) are enzymes and not small molecules. 
  • Some intriguing research relating to rapid diagnostic of bacterial infections has been highlighted at Scientific American. The authors used secondary electrospray ionization mass spectrometry (SESI-MIS) to analyze breath samples for volatile organic compounds; they could correlate MS profiles to specific infections. It's an interesting idea; given the ability of bacteria to change their metabolism quite flexibly, I'd like to see how many false positives/negatives show up in actual trials.

Reading assignments, vol. 4

The following are some interesting topics and posts from the last week or so. A lot of links, but they're pretty good.

Online education (i.e. MOOCs)

  • At the Chronicle of Higher Education, George Washington University Dean Doug Guthrie criticizes Coursera, a for-profit company that partners with universities to offer massive online open courses (MOOCs). Guthrie insists that Coursera is a fad; "thoughtful interactions" do not occur; and educators are frequently creating a crowd, not a community. It's a valid point; online education has promise but very often falls short, even with the best of intentions. See also this other criticism/analysis of MOOCs.   While we're at it, if you really want to read more about MOOCs check out this year-in-review about MOOCs.
  • In the midst of the recent surge in MOOC popularity, the University of Illinois at Urbana-Champaign is running an online Intermediate Organic Chemistry course, taught by educational specialist Michael Evans and Dr. Jeff Moore.
  • Dayna Catropa and Margaret Andrews compare MOOCs to MOCCs (midsized online closed courses), predicting that MOCCs will replace MOOCs, as they provide an opportunity to monetize the online experience and deliver it to smaller groups.

Scientific communication

The F word (funding)

  • At the Chronicle of Higher Education, Indiana University president Michael A. McRobbie warns that the fiscal cliff may spell out serious damage to research universities. He makes the case that this would be perilous to the economy, as research drives innovation in engineering/manufacturing.
  • The United States is not the only place where scientists are feeling the squeeze of a scant funding environment. Nature gives an account of Spanish scientists who protested their government's reductions in science funding (39% drop since 2009).

Scientific philosophy

  • On HuffingtonPost, Dr. Rupert Sheldrake writes a commentary on the arrogance of modern science, criticizing materialism and insisting that dogmatic thinking is "crippling" modern science. I disagree with most of what he says; it's overly dramatic, simplistic, and feels like it's pandering to the pseudoscientist crowd (as well as an advertisement for the author's new book). But it's worth reading; is this a pervasive viewpoint?
  • For the philosophically inclined, read this. (tl;dr = is science tool-driven or idea-driven??).

Blind to colorblindness

Since venturing into the more biology-oriented side of organic chemistry, I've noticed something in chemical biology and biochemistry papers that really isn't a problem in synthetic journals. Color. Biologists/chemical biologists love using color. And that makes sense; the meaning of a figure can be more easily conveyed by dyanamic coloration. Consider the following micrograph from an ACS Chemical Biology article (DOI: 10.1021/cb300171p). The figure depicts measurement of zinc levels in mitochondria in different cell types. It's a nice looking figure, and reasonably clear.


But then you go to print the articles (some of us do that) on your black and white printer and the figures become incomprehensible.



Of course, the obvious question: so what? Why not use a color printer? Or simply view things on the computer or a tablet? Content is delivered overwhelmingly by the web now; isn't it natural that figures reflect the most common viewing medium?

Well, yes. But it's still a problem for a sizeable minority (not many women, but as many as 10% of men) of the population who experience colorblindness. "Colorblindness" is a blanket term to refer to any disorder resulting in loss of color perception. Completely grayscale colorblindness is very rare, but difficulty telling red and green apart is relatively common. Variability is seen in the degree of impairment; many people are simply "red-green weak", whereas others cannot tell the two apart.  Blue and yellow are also indistinguishable to some people, though this is less common.

The previously mentioned figure would look like this to someone with protanopia, a form of red-green colorblindness (note that colorblind images were simulated using Photoshop and the Vischeck plugin).


An important thing to note is that what appears illegible in grayscale is not necessarily illegible for colorblindness; a comparative example is shown below  Thus, it's possible to use colors effectively and still accommodate the colorblind population. Take this example from a Merck drug discovery paper (DOI: 10.1021/cb2003225). The quality of the original image (left) is not significantly damaged for a person with red-green colorblindness (center), even though the figure is indiscernable when rendered grayscale (right).


Web developers take colorblindness into account. It's an important topic in website design; professional web designers must ensure their content renders to readers who can't see, can't hear, can't see well, use Apple products, or other disabilities. As such, guidelines have been set up to ensure accessibility, including recommendations for color and contrast. The W3C standards, for example, "help make the Web accessible to people with disabilities including auditory, cognitive, neurological, physical, speech, and visual disabilities" (read more here if you're interested). Validation tools are commonly employed to ensure websites meet these standards.

So why haven't some journals gotten the message?

Consider the following examples, shown in the original form on the top/left with simulated protanopia beneath/right. Both of the example figures are from a 2008 JACS article (DOI: 10.1021/ja807872s). In this first example,  the graph is illustrating the fluorescence response of a bisboronic acid rhodamine derivative to various peptide substrates in order to demonstrate its selectivity. First off, this figure is difficult to read in the first place. But in the original full color image, peptides 1 and 10 are clearly the top symbols. In the colorblind-simulation image, it's tougher to tell. Is it 10 or 6 or 4? Is it 1 or 7? 9 kind of looks close, too. There's the little lines behind the markers, but those are confusing themselves. While the text clarifies this figure further, the figure label does not.

The next example is even worse. The results of labeling studies are shown. In their original color (left) they're quite striking. But the labels are red and green. Hence, under red-green colorblindness, the pictures are meaningless.


This should be unacceptable; all modern fluorescence imaging programs have the option of changing the display color of a particular fluorescent channel; hence, it is trivial to simply recolor the red or green channel to another color (i.e. blue). Take the following figure from a Nature Methods article (DOI: 10.1038/nmeth735) by Alice Ting. Here, the authors have false-colored the fluorescent dyes (Alexa-568 is in reality red and has been colored orange; CFP is cyan-fluorescent protein and is usually cyan anyway but has been adjusted). As shown from comparing the original figure (left) and the colorblind-simulated image (right), very little detail is lost and the figure is clear.


What do the publishers say about color accessibility? Not much. Consider ACS's policy from its Author Guidelines for JACS:
Color. The use of color to enhance the clarity of complex structures, figures, spectra, schemes, etc. is encouraged. Color reproduction of graphics will be provided at no cost to the author. Color graphics should be submitted in CYMK, not RGB, color mode. Graphics intended to appear in black and white or grayscale should not be submitted in color.
Okay. No mention of accessibility. And JACS is fairly broad, and most of its TOC images even contain color. Let's also briefly consider the color policies of a few other journals: ACS Chemical Biology, Cell, Nature Chemistry, Science, PNAS, and PLoS One. There's not much point in reproducing the individual journal guidelines here, but ACS Chem. Bio., Cell, Nature Chemistry, PNAS, and PLos One all say essentially the same thing as JACS, with no mention of handicap accessibility.

The figure preparation guidelines for Science condense colorblindness to one concise sentence:
Avoid using combinations of red and green together.
Some journals are aware; the author guidelines for Nature Chemical Biology, for instance, make some recommendations (interestingly, Nature's formatting guide doesn't mention them, nor does Nature Chemistry):
Authors are encouraged to consider the needs of colorblind readers (a substantial minority of the male population) when choosing colors for figures. Many colorblind readers cannot interpret visuals that rely on discrimination of green and red, for example. Thus, we ask authors to recolor green-and-red heatmaps, graphs and schematics for which colors are chosen arbitrarily. Recoloring primary data, such as fluorescence or rainbow pseudo-colored images, to color-safe combinations such as green and magenta, turquoise and red, yellow and blue or other accessible color palettes is strongly encouraged.
Granted, for some applications, color is unavoidable; take fluorescent microscopy for example. But the ease of making color figures/graphs/charts/schemes has outpaced some journals' awareness of accessibility standards.

In practice, I think the Nature publishing group does a pretty good job with this. And it's possible these things are perhaps checked in the review process even if not mentioned in the author submission guidelines. But I don't think it would hurt to provide this information upfront.
