Jeg kan aila dig!

My three year old has already learned that she can insult us in Danish with relative impunity.  Recently, when angry, she shouts "Jeg kan aila dig!" which means "I can aila you!" only we don't know what illa is, or what Danish word she is actually using there. She was calling us "superfalig" which means, "extremely dangerous" for months before we figured out what she was saying, at which point it lost its appeal.

Having our toddler speak the local language better than we do is a comic indignity, but my failure to learn Danish has more serious consequences. While three quarters of everyone we meet here speaks decent English, the culture, administration, government, commerce, etc. are mostly conducted in Danish, and my engagement in any of these is therefore quite limited. Iris's Danish is vastly better than mine, while still far from fluent. In a fairly open and engaging society we are bound by these linguistic barriers.

Why, you may justly ask, don't I just buckle down and learn Danish? A few reasons immediately come to mind. A more-than-full-time job and two young daughters don't give me a great deal of time for down-buckling. Danish is, even the Danes often say, an unusually difficult spoken language. The correspondence between what a work looks like and sounds like is even looser than in English. Many of the consonants are silent or nearly so, and I just can't detect any differences between some of the very many vowel sounds and stops that make up most of the spoken language.

Danish teacher: The first is Å and the second is Å.
Me: You just said the same sound twice, you said O and O.
Danish teacher: No, Ååååååå vs. Ååååååå. No, you are pronouncing too hard. Oooooo is a third sound, and has long and short forms.
Me: What do the long and short forms sound like?
Danish teacher: Oooooo vs. Ooooo.
Me: Maybe we should skip to grammar.

My students say that my attempts to pronounce Danish make me sound like a drunken Norwegian. I do understand a lot more spoken Norwegian than Danish, as Norwegian is a relatively phonetic sister of Danish and I can read simple Danish. If the Danes would agree to compromise on drunken Norwegian, I would learn it.

But when my department sends me scientific reports to grade (what they call censoring), I know my Danish is not nearly good enough to know if they make sense. My course descriptions all state prominently that the entire course will be taught in English. I Google Translate every email sent out to the department to find out if it is something I need to do something about. Google Translate is less good at Danish than it is at German, for example.

Another reason for my linguistic failing is the linguistic proficiency of the Danes. One look and they can tell that I am not Danish. They start speaking English before I even open my mouth. My daughter's three-year-old friends may not speak English, but their seven-year-old siblings do.

Finally, there is the broader motivation problem. Denmark is a wonderful country in which we do not want to spend the rest of our lives. We want to be closer to family, in a more familiar and diverse culture, in a place where we speak the language (and oh what I wouldn't give for a decent bagel, or a burrito with spicy black beans and nopales). Knowing that we don't want to stay makes it easy to not learn, which makes it easy to not want to stay.

This experience has reinforced my long-standing intolerance for the intolerance toward immigrants and linguistic minorities that is very much on display in many parts of the US and Europe. I could spend the rest of my life in Denmark, and actually apply myself to learning, and would never speak the language well. Those countries that have the harshest attitudes towards immigrants tend to be the ones that need immigrants the most urgently. And being an immigrant is hard enough, even in a relatively accepting culture like Denmark's.

Getting a paper rejection from a journal is always frustrating. So much time, effort and care goes into a paper that to have anonymous strangers say its no good can't help but hurt. I've just had a paper rejected, and it still hurts even though they had nothing bad to say about the paper.

The starfish paper I wrote with my students documents something that hasn't been documented before, but is certainly not the world's most important paper. It doesn't fit neatly into any field or derive from the pressing questions in any literature. So we sent it to a journal that explicitly says they don't care if it is important, so long as it is original, technically sound research. The reviewers agree that is passes these hurdles, but question its importance to their field. On this basis alone, the academic editor rejected it. I can't say I'm entirely surprised, as PLOS ONE has become a relatively high-impact journal. That type of success naturally brings them to function like a more traditional print journal competing for the flashiest papers. I filled out their feedback form to suggest that they update their stated criteria for acceptance, but won't otherwise protest.

There are two upsides to all this. The reviewers found the paper convincing and novel, with no technical or language faults. So we just need reformat for another journal and submit it there. Perhaps more importantly, this gives my student co-authors a window into yet another aspect of the scientific process that most of their peers never see.

Unsolicited parenting advice

I have decided to share with you one of the big points of baby raising that Iris and I learned by hard experience.

We have a million books on baby care, Iris reads a bunch of "mommy blogs," and we know lot of people with babies; we felt quite confident in our baby skills before our first daughter was born. For the most part that confidence was justified, but there was one thing we just had no idea about. Once we figured it out, it transformed our parenting experience: helping a baby fart. One hears all about midnight feedings and how to deal with diaper rashes, but we had no idea it was necessary to help a baby fart. She would be crying inconsolably, and we would be going crazy trying everything we could think of to sooth her, and then at 3 or 4 or 5AM, she would finally fart, and immediately fall asleep. This happened repeatedly for weeks, maybe months, until we figured out that belly massage, light pressure on the belly, or alternatively pushing her knees up toward her belly would squeeze the fart out. With practice one can feel exactly where the gas bubble is and guide it up and around and down and out. We got good at this, and could make her fart almost immediately, bypassing the hours of gas pains and ear pains. 

P.S.  Another thing I found very useful, when woken up for the 14th time that night, was to have a posted list of things to try to help the baby. It seems like it would easy to remember to check the diaper, but when sleep deprived enough this can be quite hard. So here it is:

Belly Massage
Clean skin

In almost every case where she wasn't actually sick, one of those was it. Print it poster size and put it near a nightlight.

This spring I taught a field course in terrestrial zoology at Svanninge Bjerge, a nature area owned and operated by the Bikuben Foundation. The foundation had Casper Tybjerg, a well known Danish photographer, join us and take photos. Bikubenfonden has featured the course on the Svanninge Bjerge website, including posting many of his photos (including the above). If you start here, and click to the right, most of the next several dozen photos are from our course, and all are beautiful. The accompany text is in Danish.

It makes me all happy and proud and sad-that-it-is-over to look through these and remember what amazing fun that course was.

Student scientists study sea stars, produce plaudable publication

A good university science education should give students the opportunity to engage in scientific research. This is widely agreed upon, and most of the biology position announcements I consider state that the successful applicant's research should present opportunities for student participation. The general model is that the professor has the research program, and a question that needs answering, and a plan for answering it, and the student gets to see how research happens by carrying out, or at best refining, that plan. I'm all in favor of this, but I'd like to take it a step further.

My first publication, way back in 2003, was with one of my professors at Bennington College, based on work that she planned, and I, as an undergraduate, helped carry out. I made alterations to the experimental protocols, did a lot of lab work with minimal supervision, and chose to work on this project rather than others that were available, but I can take no credit for any of the ideas in the publication. In retrospect the one thing I would add to my own undergraduate education, if I was to be my own professor, was working through the entire process of generating a primary paper, from initial observations and idea generation to publication.

Implausible you say? Impracticable? If generating publishable science is so easy, why doesn't every professional scientist publish a paper a week? Well, I've just finished doing it with two of my students, and I'll tell you about it.

'Finished' is vague. We've submitted the paper, and I think it good, but we have to wait to hear if the reviewers agree. I'm not going to give you too much detail on what we found because you'll have to read the paper (or a future post) when it comes out.

It happened like this: At SDU, where I currently work, all natural science students in their second semester have to complete a group project. A group of students (four in my case) are assigned a faculty mentor who gives them a question to answer and guides them in answering it. In my case, the question was, "Can we use PIT-tags (like a vet puts in your cat) to mark starfish for a long-term demographic study?" We brought some starfish into the lab, talked about animal care and experimental design, showed them how to inject the tags and pretty much let them do their own thing.

They did great, but the tags just kept coming out. After a few weeks, all the tags were out. They answered my question with confidence: No, PIT-tags cannot be used to mark starfish long term. But the thing is, they didn't stop there. With no pay, no additional course credit, no requests for recommendation letters or such, two of the four students just decided to keep going. We met occasionally and I offered encouragement and comments, but little more.

They presented their results to the Evolutionary Demography Society, and long after the course was over they kept doing more experiments to figure out how the starfish were ejecting the tags. Notice that this is their own question. I asked, "Do the tags stay?" and my students answered this then asked, "How do they get rid of the tags?" And when we had an open house at the laboratory, they presented what they had learned to the public. Just by chance, one of the visitors they talked to had access to an ultrasound machine. This let them repeatedly image exactly where within the starfish the foreign body was moving. A year after they started, they convinced me that they had discovered, and had the data to back up, a previously unknown mechanism by which starfish can eliminate foreign objects from within their body cavities. "Okay," I said, "write it up for publication, and tell me now by what date you will have a finished draft." They missed their self-assigned deadline. They needed more help with data analysis than they expected. They put in all the wrong references in all the wrong places, and the flow of the article was terrible. English is not their first language. But not so long after they said they would, they sent me a draft that had most everything I needed to make it good. With the co-authorship of a couple of marine biologists (did I mention that I know next to nothing about starfish and have no other starfish research ongoing?) and with the continued input of these two students, we made a respectable manuscript out of it.

What lessons do I draw from this? Motivated undergraduates, with just enough guidance, can basically have their own successful research programs. The paper we produced still took a bit of my time to write up, and isn't the most important paper in the world, but they discovered something completely new (answering a question that someone who knew the literature would never think to ask), and they learned. They learned a lot. Refining questions. Starfish anatomy and function. Experimental design and practice. Ultrasound imaging. Cox regression in R. Scientific English. Literature searching and use. Collaboration. Communicating science to peers and the public. Preparing and submitting a manuscript for publication. Now they will get to see how peer review really works, or doesn't. These students, just starting their third year as undergraduates, have a fuller experience of what goes into making a scientific publication than I did when I started my third year as a doctoral student. Chew on that for a minute.

It is important here to think about these students' motivation. Judging by their grades, they are not academic stars. Neither of them has described a lifelong fascination with starfish. They did this, so far as I can tell, because it was their first chance to truly be scientists rather than just science students.

I told them early on that:
A) That they would have a strong say in the direction of the research and
B) that if they produced something publishable, I would help them submit it for publication.

These are not promises to be made lightly. Publishing things, especially things outside one's own central line of research, is time consuming. Giving first year undergraduates even this limited version of academic freedom in their research is, understandably, not common practice. But it seems to me to be damn good educational practice, and I plan to continue offering this type of opportunity to students when possible. Students will do much better, and more, work when they are exercising agency and following their own curiosity. Even if they don't choose careers in science, they know how science happens from start to finish, and that is surely something science students should be given the chance to learn.
