So about a week after getting to Arizona, I finally finished a reasonably thorough draft revision to a manuscript I'll call the 2018 seed-harvester ant paper, and sent it over to my hosts, who are coauthors on it, for their review and feedback.

Then, while in the transition phase between that and the next writing project, I had one of those thinking-out-loud conversations that went, "Oh yeah, of course the next writing project I should work on is the next paper that's closest to being ready to submit."

...That would be a leafcutter manuscript rather than the next seed-harvester paper (the "2021 seed-harvester ant paper").

...the only major downside being that switching from seed-harvesters to leafcutter ants is kind of a big intellectual shift, for me, at least. To wit, I spent a bunch of time last week just trying to get my leafcutter ant annotated bibliographies better organized (yes, that's bibliographies, plural), to identify where I need to brush up on the literature, and since then I've been spending a bunch of time trying to find and read any information I can about how fungi might respond to excess nitrogen (protein).

Half of the challenge tends to be just figuring out how to dial in on what my question actually is, to figure out how to search for sufficiently specific information related to my question. "All fungi" is FAR too broad; I really just want to learn about saprotrophs - and soil saprotrophs rather than wood saprotrophs, but often they get studied in the context of "soil microbiota," which will also always include ectomycorrhizal fungi and bacteria, okay, rightly so. But the thing is, the context of other microbes might actually be really important, seeing as most leafcutter ants grow their fungus gardens underground. They do keep their gardens immaculately clean, but there are still bacteria in the mix.

Out of the papers I found, I only finished reading the best of them yesterday and today - a review article from 2014 that basically laid out a great framework for thinking mechanistically about how soil microbial communities could and do respond to C, N, or P limitation (so interesting and cool*), and a fun paper from 2024 that helps to clarify that there are some systematic patterns to fungal fruiting body element content, related to both fungal evolutionary history and ecology. The latter is important for being able to assert that fungi regulate their body element composition homeostatically.

Things I'm still not entirely clear about: in soil microbial communities, when there's an abundance of nitrogen around, it sounds like basically "microbes" (presumably mostly bacteria rather than fungi) produce and excrete "mineralized" nitrogen (ammonium) - a form of nitrogen readily available to plants. This basically means plants will renege on their deal with ectomycorrhizal fungi and just get their nitrogen directly. In contrast, when nitrogen is limited, microbes are said to "immobilize" it, which basically means they hold onto it and put it to use in forms that are not directly accessible to plants. (that would lead plants to barter with fungi for nitrogen in exchange for some sweet photosynthesized sugar).

But: do fungi also mineralize nitrogen? If there's too much nitrogen around and not enough carbon, are fungi more likely to die by way of simply running out of energy (can't get to enough organic carbon), or from some form of nitrogen toxicity, perhaps related to having lower tolerance to high nitrogen and getting outcompeted by microbes with higher nitrogen tolerance?

That's what I still don't really know and can't fully conjecture about.

This line of speculative thinking will probably only contribute to 1-2 sentences in the Discussion section of the leafcutter ant manuscript, but on the other hand, it's fun and interesting to think about.

...And so only eventually have I been able to get back to working on a coauthor's feedback on the 2018 seed-harvester ant manuscript.

I wasn't quite expecting so much of this time to get devoted to the writing step of reading papers and learning things, but here I am.




*Responses differ depending on the limiting element/nutrient (out of C, N, and P), because the extracellular enzymes that these organisms secrete in order to obtain nutrients require nitrogen and energy (but not phosphorus!) to synthesize. Fungi and microbes don't appear to store appreciable amounts of nitrogen, but they DO stockpile phosphorus! If nitrogen is limiting, that will then favor organisms that can burn a bunch of energy to get N (consider N fixation, for instance). If C (energy) is limiting, that will favor more energetically-thrifty organisms. P limitation will favor organisms that can store and transport phosphorus from one place to another (fungal hyphae FTW!).

This week: successfully unsnarled the Introduction and Methods for a manuscript I'd like to get submitted soon.

I haven't revisited the Results or Discussion yet. A project for tomorrow.

I do think I'm getting closer to submission, at least. There's at least some small hope I could get this submitted by the end of the month, which is really important for tenure, largely because I need to work on writing the sequel and try to get that submitted by the end of July.

No pressure.

One of the challenges of academic writing is that I have to continually persuade myself that the things I'm reporting on have some small significance or importance or insight to offer. This is often the most challenging aspect of writing for me. I'm not curing cancer or solving world hunger, but hopefully I am at least enriching our understanding of and appreciation for the natural world.

1. I met with my coauthor last night and we made very good progress on this manuscript! The next steps will be easiest on my work desktop computer. I am excited to get back at it. This coauthor/colleague/collaborator is a great reminder of the power of positive encouragement.

2. I just finished reading The Unseen, by Roy Jacobsen. I HIGHLY recommend it. It is so satisfying to read a beautiful piece of literature.

Not so good: I have a #@$%*$#^& head cold. It's just in my sinuses. My nose stops running and I stop sneezing when lying down, but the moment I'm upright, the secretions ooze, drip, and spray. Gross. Clearly, it could be worse.

I am revisiting a manuscript I've had a hard time touching in a while. Time is a tool, for writers. Sometimes we can instead attain distance from a piece of writing by handing it over to other people, who can help us discover the intellectual ruts and pitfalls. But at other times, there isn't an other to whom we can make the request.

With time, we can reapproach with new and different eyes. Between my last visit and this one, I've reviewed more manuscripts, and I have taught the scientific writing course here three times. Both have helped me practice and articulate what constitutes a more effective piece of scientific writing. What now jumps out most readily from this old manuscript is how plodding my text was.

The downfall of plodding text is that it dooms exciting findings. If it won't sparkle for me, why would I expect it to sparkle for anyone else?

One of the other issues I've been thinking about between then and now, is how to best reframe the work. The old intellectual frame never fit well to begin with, but it was hard for me to articulate why, because I had less of an intellectual context when I wrote the manuscript. A funny part of that is that some of this wasn't really my fault; when I first wrote the manuscript, some of the intellectual context didn't exist in the way it does now. I have also learned a lot more biology between then and now, biology that fits better and will better support the work.

In any case, blogging about writing is an excellent way to procrastinate from the more painful work of actually working on the writing.

Predictably, the constant meetings and work earlier in the week wore me out to the point where I couldn't rouse myself for rowing practice this morning.

It snowed yesterday, the kind of snow that makes everything pretty and makes the roads sloppy but not impassable. I'll take it.

I'm slowly clawing my way through the list of reference letters to write. One of my hourlong meetings yesterday was with a student struggling with writing where we had to start out by diagnosing what the big issue was. Conversation indicated it was most likely largely a case of perfectionist self-editing - that's where when a person sits down to write something, they write out a sentence and then immediately get distracted by questioning the sentence and whether or how it needs to be rephrased. I have to admire this student for figuring out how to get the help they need with their academic work, but on the other claw I need to maintain boundaries so I can get my own stuff done someday.

The thing is, I also tend towards perfectionism when working on reference letters. I consider it unethical to write anything other than the strongest possible reference letter I'm capable of. So, that has been exhausting. Some day I will add up the total number of reference letters I've written over the course of my lifetime. The trouble is, as I've noted, I only get a limited amount of writing energy in any given period of time. While it will be good to see all these students go on to do great things, and I suppose I can claim that as part of my overall legacy in life, I sure would like to get more of my own work and writing out into the world, too.

Anyway, back to work.

On Sunday at around 2 am, an undergraduate student at my institution died. I received word about this when I checked my email Sunday morning, in a message from our College President. This isn't the first time that a student has died (nor do I expect it to be the last, unfortunately), but just as every student is unique, every incident is unique. We are all born into this world, we inhabit it for a time, and we die.

I didn't really bring things up with the freshmen I am teaching; the student who died was a junior, so I had to figure they might not know the student so well, and besides, with other things that have happened with that freshman class this semester, I think it's pretty clear that I understand that they can have a lot of shit going on and I am there to help keep them safe as I can, et cetera, in the context of our shared goals to enjoy science and learn stuff.

Not so much my other class. Even before class a couple of students got in touch because they are pretty messed up right now. In that initial message as well as in follow-up messages, the college did its due diligence in terms of pointing out support resources and holding gatherings for students.

But of course, that's not always enough. In conversations with students, I of course go back to thinking about Zack's disappearance and how much that messed me up as a basis for comparison - and that was in an era where things weren't so overshadowed by a global pandemic, and during grad school, where the pace of events is different.

I also wound up sharing a bit about my existential struggles with my research students: how can I possibly focus on writing a paper about some silly and esoteric topic when there are so many very real struggles happening right now? It takes a huge amount of willpower.

And of course I also wind up thinking about my father, in more ways than one. He has told me stories about the point in his life when he had moved to Berkeley to go to grad school, where there was one particular pivotal day. He had moved there to pursue a PhD in Physics, but shortly after arriving it became clear that his undergraduate Physics education was inadequate preparation for the rigors of the program at Berkeley. Things came to a real head for him one day while sitting in class, where the professor teaching the class made some remarks about the Vietnam War draft and ongoing protests at Berkeley; at the end of that class my dad got up, walked out, and never returned.

Among everything, when I do some soul-searching, I still deeply want to work on and finish up these silly academic manuscripts - throw them into the massive river of data and findings and discoveries, even knowing that the current rate of paper churn does not correspond to anything resembling substantive progressive change, scientific, social, or otherwise.

As I was biking home yesterday, trying to process everything, it came to me that rather than seeking progress and advancement in these academic works, perhaps I should rather approach them as prayer instead. The assembly of thought and ideas and careful hours spent in the field and in laboratories, deepening at least my personal understanding and respect for the world around us. That is something easier for me to justify doing. With prayer, we cast our thoughts and intention outwards, knowing that we may never get any response, or that the response may take a form we could never have anticipated or come up with.

In a related fashion, I think about and talk to my memories of my father while riding around on my bicycle; the lucky pennies I encounter are small reminders to pause and have gratitude.

I can see some of my students caught up in a horrible swirl of events right now; one encountered a professor utterly unsympathetic to a missed class and is now worried about winding up with a lower grade because of it. And that touches on a point: having doggedly continued to pursue their studies in the midst of the global pandemic, many of these students are still very much feeling their way around in the dark, because the old academic standards and expectations from the prepandemic era have shifted in uncertain and confusing ways. In some cases, students who should not have passed a course were able to pass that course; if anything, grade inflation has been exacerbated. A lot of the back-and-forth feedback between professors and students became heavily filtered and diminished because it was forced onto digital platforms. It is massively confusing.

But the need for those conversations and for that back-and-forth doesn't magically go away. More than anything, if my ultimate goal is learning, I have to make my expectations for students less rigid, while still providing enough structure and incentive for them to keep going. In so many cases, often what we wind up learning differs from what we set out to learn.

What I am really hoping is to ask them to take some of these recent and horrible experiences and find a way to continue forward. This is different for each of them, so I think the best I can do is try and tell them some stories about my own writing and struggles to keep moving forward. I think it comes down to saying, well, here we are, at this college. What are the best ways that we can honor the memories of those who have died before us? I think those who have died before us would call us to continue trying to be our best selves, to do our best work, to leave a positive impact on the world and those around us. So let's do what we can to pick ourselves up and honor those memories and move forward.

I finished reading Being Mortal, by Atul Gawande last night. I'd been hearing about it on several fronts, including from our former Farmer House neighbor, who is a wonderful thinker and atheist coping with her own imminent mortality from cancer. My mom had also requested that we kids read the book because she is someone who wants to have that series of tough conversations about how to go through the process of dying.

I can understand why: we have the stories of my great-grandma D and my grandpa W to reflect on, in addition to the stories of my Aunt Penny, and Grandma and Grandpa C. In addition, there's the looming spectre of my dad's cancer, where even if he has a 10-year horizon, we should still all think about how to spend that time well. I am grateful for parents who seek out these conversations.

Anyway, the book shares a whole series of insights about how we treat old age and the act of dying, and offers up a series of ideas and examples for things that seem to help make those experiences as good as they can possibly be. Given that we are all mortal, everyone should spend at least some time thinking about how to cope with the end stages of life.

But there was one thing I deeply appreciated while finishing the book: in the Acknowledgements section, the author not only talks about all of the people who helped with different aspects of the writing, but where he also slips in a comment about how he has NEVER found writing to be an easy process. This is especially comforting coming at the end of a well-written book.

I took a break from writing, while working my way through this last cricket circadian experiment. It's impossible for me to write while conducting that kind of research, where I am constantly trying to stay mentally ready to run experiments at all hours of the day and night. But now I need to return to writing on two fronts: job applications and manuscripts. I think the author's comments are a comforting reminder to be compassionate towards myself while I work on these projects. I'm feeling a whole host of emotions about writing right now, but the ones that stand out are guilt over leaving things to sit for so long, severe anxiety over whether I will manage to get things done and over the sense of vulnerability that accompanies job applications, and anxiety over how to carve out time and quiet space to write productively, while living in a loud, chaotic house and working in a loud, chaotic lab. I also miss my grad school writing buddies. But I have a feeling that I can't just wait for more writing buddies to show up. I need to buckle down and get to work no matter what.

I finished reading Insect Diets: Science and Technology. A lot of the later chapters seem to generally reiterate subjects from the earlier chapters, or talk about issues specifically associated with mass-rearing, which is defined as rearing millions of insects, as for a large-scale sterile release program. Those are subjects that aren't as directly relevant to me, so reading those chapters was a bit of a slog. My next fun academic reading project will be to read the newly-published edition of Biochemical Adaptation. I should also work my way through the rest of Protein Turnover to see if there are any specific subjects I need to know more about and think over.

Not too long ago, I read this interview of Robert Caro, author of the book The Power Broker, which is about a guy named Robert Moses who had a huge influence on shaping the urban fabric of New York City and its surroundings. While the stuff about Robert Moses is fascinating in and of itself, I also appreciated all of the discussion about what it's like to go from journalistic writing to writing an in-depth investigative book.

I'm also envious of the writers getting to use the research and study rooms at the New York Public Library. Those spaces just sound so heavenly and productive. My rough equivalent is going down to the Biosciences Library on the second floor to sit at a kiosk among all of the undergraduates, who have special savory habits like wearing WAY too much cologne, talking on their cell phones, talking to each other, and bringing in take-out food to eat and slobber over in the "group study" spaces. And this is at a fairly studious university, overall.

Maybe there are other secret writing spaces on campus that aren't so terrible, but if there are, I haven't found them yet.

This article on overcoming the pain barrier in rowing talks about critical aspects of mental training for rowing. It highlights some of the key traits that rowers have to address to perform at their maximum capabilities. That's part of what keeps me going as a rower - knowing that continuing to work on mental training will have positive benefits for how I live my life in general.

Meanwhile, here's Anne Lamott on how to find time to write. It's funny - I wound up following her on Twitter, which is a mixed blessing because she posts a lot of political stuff that I don't care for. On the other hand, she's so good about addressing emotional aspects of writing, and I found Bird by Bird satisfyingly encouraging, so occasional things like this are a good boost.

That piece by Anne Lamott motivated me to show you a figure out of the book How to Write a Lot:
Writing motivation

These are data from a writing experiment conducted with a group of academics. The "abstinent" group was asked to not write anything for the experiment duration. The "spontaneous" group was told to only write when they felt inspired to do so. The "contingency management" group was told to set up and maintain a writing schedule.

And on that note, time to abscond off to the library to work on my research statement for job applications...

Wouldn't it be nice if demanding a revised draft of a manuscript NOW resulted in such a thing?

Sigh.

Instead it seems to just push me over the edge of the stress-performance inverted U-function.

To some degree, this has to do with how I process feedback from other people. It's an instinct to drag my heels and fight because I *know* that I know the literature way better than coauthors and am trying to think it through on a deeper level than they are. I refuse to turn in embarrassing and shoddy work. And I know this is to my detriment at a certain point, but I've also observed firsthand that turning in stuff that's half-baked is seriously embarrassing and an even larger waste of everyone's time.

Just a brief update regarding that troublesome manuscript I vaguely referenced earlier in the week. Somehow*, between yesterday and today, things started coming together, so today I got it turned back over to my co-authorsbosses. Ka-POW!

Now back to eleventy-hundred other projects. But still - this is the pace of writing, for me. Several agonizing days that feel slow, stupid, and sluggish, and then finally, an actual sense of progress. I think some interesting things can come of this particular manuscript, but it's going to take a lot of brain-power to get it there.


*I was in really bad physical shape yesterday, which partly explains some of my woes. I woke up with a sinus headache at 5 am, which didn't go away until I took a Tylenol at 11 am, and even after that, the weird leg muscle thing was bothering me and I was generally sleepy and stupid and unproductive. A classic example of why experts caution people against just diving in to a new exercise regime. I knew that was a risk when showing up to a new ride, and repeatedly checked in with the other riders. Even with all that, it's too easy for me to get all excited and push myself too hard. Live and learn, hopefully.

I'm struggling with the current cricket manuscript, but it occurs to me that one of the subliminal elements in the struggle is an underlying power struggle. When I started my PhD, one of the things I strongly respected about my advisor was the emphasis she put on her students owning their own dissertation research. This emphasis is not an easy one for anybody involved, and comes at certain costs, but with certain benefits as well. She actually developed this emphasis in reaction to several unfortunate events, one of which I'll briefly describe. The main unfortunate event involved a student mentored by her husband (also an academic), who was carefully shepherded through the early stages of their* PhD, up until they had to take their comprehensive oral exam and defend their dissertation proposal. Well, this student got up in front of their committee and couldn't explain themselves to the committee.

It is important to know how to collaborate, yes, but in the American system it is unacceptable to outsource one's intellectual development, so clearly this situation did not stand, and it was a hard experience for all involved - a great sense of shame. When an advisor lets an unprepared student get up in front of a committee, it usually indicates poor mentorship, not failure on the part of the student - at least, mature committee members should be cognizant of this distinction and not abusive of their power over the student. At the same time, it's also impossible to predict how committee dynamics will shake out. Sometimes committee members feel it's important to prove their intellectual chops to each other, and use the unfortunate student as a punching bag in this exercise. I hope this generally isn't the case, and more than anything it again can reflect poor mentorship on the part of the advisor, who is hopefully sensitive to the interpersonal dynamics among the faculty to a degree that he or she can steer a student clear from such trouble. In my own case, I intentionally chose an intellectually challenging committee, and was rewarded by some tough questions, but I did so for the purpose of putting together as good a dissertation as I could muster. And I intentionally avoided having certain people as committee members based on recommendations about how well (or unwell?) they worked with my advisor's academic style.

So then, the postdoctoral experience. There are some fields where one's personal research activities are most effective if they're closely guided by more established researchers. In physiology, it's very difficult to throw undergraduates into a laboratory and expect them to come up with groundbreaking experiments. In many cases, it makes more sense to hand them a chunk of a larger puzzle, so they can make a meaningful contribution over a shorter timeframe.

But that's undergrads, and I'm referring to the postdoctoral experience. Postdocs can fall into a similar category, depending on the nature of the project, funding, and the project timeline. If I had been successful in acquiring my own funding, presumably I would be working on a project over which I felt and had more ownership, and would feel more power to steer the ship myself. However, in accepting the postdoc position I accepted, I voluntarily gave up some of that power. But I did so knowingly, because I saw the position as an opportunity to gain a number of useful skills that I could apply to other contexts in the future. And I've definitely gained those useful skills.

The challenge is, that doesn't make the power struggle go away, and it's a double-edged sword. On the one hand, my co-authors are awesomely enthusiastic and excited about my experiments and the papers I'm working on. On the other hand, at times I have followed suggestions and pressures down blind alleys due to this power differential, when a part of me was quietly raising doubts about the navigational decisions early on. This leads to regrets.

The difficulty of the situation tends to manifest most strongly when staring at a half-written manuscript. I find myself rehashing out the whole series of decisions that led to the present state of the manuscript (the data analysis), and start experiencing doubts over the direction of the manuscript and what to do next (massive "Now where was I and how did I get here?" reiterations). By this point, I know that I have to think myself out of this particular box at this particular point, and find myself wishing I were willing to be just a bit more obstinate about things in the early stages. Then again, I've always liked to collect lots of data, and in a lot of cases more data makes things harder, not easier.

Despite all of this emotional baggage, I must still forge on, and persevere. As my graduate advisor would say, there's no such thing as a perfect experiment. That said, there are insights to be gained from all experiments, but we must get back to work to find them.

And on that note, perhaps now I can get back to work on this pesky manuscript.


*I don't know the student's gender, and this pronoun seems more straightforward than "she/he."

I'm thinking about rewriting my teaching statement for these job applications. Alternatively, I might just write another document, a Teaching Manifesto, intended to reach a broader audience beyond hiring committees, because over the years of my own education and teaching I've reached a specific perspective on educational goals, and I'm starting to think the whole thing deserves to be its own essay.*

Part of the reason I bring this up is because I first heard about the subject of this post, the book Bird by Bird, by Anne Lamott, in my undergraduate Writing Fellows training seminar, and the Writing Fellows experience continues to inform how I approach teaching. I'm not quite yet at a point where I'm ready to write the shitty first draft (Lamott lingo) of my Teaching Manifesto, but when I do I suspect you'll be the first to hear about it.

Bird by Bird is twenty years old by now, but it's a timeless book for writers because Lamott does a phenomenal job of reaching out and capturing the thoughts and emotions one experiences as a writer. While her intended audience is primarily writers of fiction, writers of all stripes will find in her work someone who is sympathetic to the struggles of professional writing and able to offer up both consolation and kicks in the pants as necessary.

While reading the book, though, I kept thinking back to a comment [livejournal.com profile] scrottie made while I was reading Working: People Talk About What They Do All Day and How They Feel About What They Do, by Studs Turkel. He had a hard time with the idea of reading Working because the concept of reading about work just sounded like a whole bunch of work! However, that wasn't my experience of Working - Turkel did such an amazing job of capturing the different workers' voices and their passions for what they were doing and purposes behind their work, that the book is a rich and fascinating compilation about the human experience.

Reading Bird by Bird was closer to work than leisure reading. I read most of the book while traveling, where I didn't have the mental space to settle in and write, so it also involved reading about work instead of just going out and getting work done. Today, after finishing it, I wound up bringing the book in to work so it can sit next to How to Write a Lot, which looms on a bookshelf right above my desk for maximal impact.

And on that note, perhaps I should get back to work.



*The other day on a different social media platform, I posted a rather simple commentary piece on how most students don't know what learning is, but in the same vein, there's some odd tension in the biological sciences over teaching methodologies, too. With teaching philosophies, it can actually be dangerous to be overly pedantic, and at the same time, many biologists teach poorly or use uninformed teaching methods. So - the Manifesto will start with my perspective on the purpose of an undergraduate education, and will then cover specific tools and approaches that should be used to facilitate student development, as informed by my experiences in grad school and as an undergraduate Writing Fellow.

I made myself go in to the lab today to force myself to work on job applications.

Instead, I made some decent headway on a leafcutter manuscript that has gotten the back-burner for the past three weeks while I've scrambled to get other more immediate things done. You know, like all those talks and workshops and cricket manuscript revisions and manuscript reviews.

Not a total loss. But for this week, I am going to have to set a goal of getting out one application per day, on top of writing a conference talk and wrapping up the cricket manuscript resubmission.

Working on a manuscript is a pretty terrible form of procrastination, if you know what I mean.

Bike fashion is in the news again (NYT). There was some interesting commentary on this piece in the Slow Bicycle Movement group, noting that this sort of crazy coattail-riding bicycling fashion craze has happened before, but I think there are two different elements to consider in the present case. One element is that the technology for incorporating reflective material into clothing has only recently been developed, so it's still something of an experimental arena for fashion designers. Bicyclists are a logical target audience in the US because we Americans have done a fantastic job of designing our transportation infrastructure for cars, to the point where anyone interested in riding a bike for transportation spends time deliberating on whether or not to go the traffic-cone route. I'm reminded of this book that I just started reading that talks about many peoples' conflict-of-interests between wanting a feline companion but not wanting a home that's festooned with beige carpeting and litterboxes. Anyway - I like the reflectivity from an aesthetic standpoint, and mostly I just hope someone gets womens' pants right, one of these days. I plan to check out Clever Cycles's pants selection when I'm in Portland next month. I like the look of this shirt, but for some reason I'm still failing to find women's short-sleeve button-down dress shirts. I tried one on at Goodwill last Saturday, but it had poofy sleevelets and squeezed my biceps - a no-deal.

I only recently discovered that the League of American Cyclists has a bike-friendly university list. None of the universities I've attended are on the 2013 version, but I'm pleased to see that Arizona State has managed to step it up and get on the list for 2014. The improvements are noticeable.

In the realm of simple living, I'm working my way through thinking about my relationship with sentimental items. I think the author makes a valid point about emphasizing the importance of shared stories over sentimental items, but I'm still working on figuring out an appropriate system for acknowledging the presence of the sentimental items and then letting them go. Can't say I've pulled out my high school yearbooks in a number of years.

Words of encouragement for sharing your writing in public. This post on coping with insecurity also feels related.

The psychology behind Social Media Brand F's 'success', which is important to consider when thinking about how we use it in our lives. While I was off traveling over the past two weeks, I spent substantially less time on social media sites. Now that I'm back in Texas, it's featuring prominently in my procrastination loop, I think because of differences in how my social interactions are structured out here. Traveling was socially overwhelming, but also included time spent with [livejournal.com profile] scrottie, and the long-distance absence is still just as hard, if not harder, now, as it was when I first left Arizona.

Lastly, how about an intriguing video demonstration of cymatics? One of the presentations at the recent Bio-math meeting, mostly focused on computational questions in topology, included this video. Turn off your computer's sound after a certain point.

The cat is making small noises as she sleeps on top of the heap of freshly-cleaned bedsheets.

I spent too much of the morning procrastinating, by vacuuming the house, cleaning the litterbox, cooking crepes, watering the garden, tending the worm bin, washing dishes, and doing laundry. I draw the line at lawnmowing. I skipped the household trip to Austin so I could get work done today. Time to shower and trim my fingernails. I'm spending the afternoon being irritated by incidental noises: the next-door neighbor's loud radio music and barking dog, someone else's leaf-blower, the mariachi music of the neighbor across the street. My small table, adjacent to the cat's litterbox, makes me think of Jane Austen's writing spot. I can't force myself to sit still. If I sit in the living room, the cat yells at me because she's on the other side of the fence. When all the chores are finished, I'm sleepy and slightly hungry. Time for a snack. Maybe time to cook some dinner.

Three paragraphs down, two paragraphs to go. Let go of the need for a perfect first draft. Let go of the need to intensively scrutinize the literature. Let go of the side points, about incidental things from other studies that are only tangentially related. Stop aimlessly web-surfing. Let go of constant connectivity.

I once naively thought that if I lived in a place with fewer distractions (=moving to Texas), I'd be more productive. That might still be true, and the lesson I might have learned is rather that when I'm relatively satisfied with my life, I'm more productive. Hard to say for sure. I create my own distractions no matter where I live.

A week or two ago, I suggested to [livejournal.com profile] scrottie that he read A Room of One's Own, by Virginia Woolf [he'd previously been conflating it with Who's Afraid of Virginia Woolf, which is completely different and irritating, as best as I can tell*]. He wound up reading it last Friday in an epic five-hour bathtub-sitting session, and pulled out a few quotations to share with me. Here's one that he found a touch hilarious because it suggests Woolf is as enamored with food as I am:

"One cannot think well, love well, sleep well, if one has not dined well. The lamp in the spine does not light on beef and prunes ... if she had left two or three hundred thousands pounds to Fernham, we could have been sitting at our ease tonight and the subject of our talk
might have been archaeology, botany, anthropology, physics, the nature of the atom, mathematics, astronomy, relativity, geography. If only Mrs. Seton and her mother and her mother before her had learnt the great art of making money and had left their money, like their fathers and their grandfathers before them, to found fellowships and lectureships
and prizes and scholarships appropriated to the use of their own sex, we might have dined very tolerably up here alone off a bird and a bottle of wine ... We might have been exploring or writing; mooning about the venerable places of the earth; sitting contemplative on the steps of the Parthenon, or going at ten to an office and coming home comfortable
at half-past four to write a little poetry."

But it remains painfully true for me that a thousand little pinpricks seem to interfere with my ability to concentrate on and think and write about certain scientific subjects of interest. Friday was a dismal day, despite my running off to the Medical Sciences Library's Quiet Study area for real, honest Quiet. Yesterday, I started to finally converge on the appropriate context for what, in shorthand, I've been calling the Cricket Respirometry paper. I wish I could think faster, but sometimes I just can't. At least I *know* when I've settled on the appropriate context, after reading and thinking about 50 different papers on the topic.

The mental and emotional energy can be exceedingly difficult to summon, though. So much so that I couldn't will myself out of bed and over to the Rec Center this morning, and I couldn't will myself to head in to the office, either. A brief mental illness. Eventually, after lying in bed for a while, things started whirring and clicking and humming again. I often despair that these shoddy work habits mean I'm not cut out to be an academic, but then I return to the short-term mission of getting my hard-won, taxpayer-funded work out into the world, and those thoughts send me back to the keyboard. There are other fields that require the development of this sort of thought-space, although probably too often programmers wind up having to turn something in before a deadline and don't have a chance to fully develop their work. On the flipside, stuff needs to be declared "finished" after a certain point, even with its imperfections, and the book How to Write a Lot is still a useful kick in the pants.

And so.


*I tried to go to a production of the play at Tufts, but got there 20-30 minutes late, so I sat outside of the the theater and tried to just listen through the first act, which sounded dull, and now I can't remember if I then decided to leave or if I sat through the second act as well. Regardless, I'm not especially motivated to give it another try. This also reminds me of my own conflation of The Society of Mind with a certain other institution of a completely different nature that calls itself something similar.

I'm still staring down the throat of a lot of academic writing projects.

I procrastinate by reading stuff about how to write.

The false promise of an office at this institution is still one of the things that most greatly angers me about my experience here. A desk in a laboratory does not have a door that can be closed. A hallway to someone else's lab space is NOT an office.

My living situation for the fall is going to be even more full of people than the Villa Maria house. The Villa Maria house was already too crowded. Hard to think there.

The library on the main campus has individual study rooms available.

I will make appointments with myself, to go to the library, and write.

There are certain stages of the writing process that get to be a real slog. Mostly, the "refinement" stages. I spent a ridiculous portion of the day yesterday trying to make sure I had a solid understanding of everything that's known about connections between diet and resting metabolism (short answer: not much, actually). Part of the problem is that most efforts to classify and measure what different animals are eating have been inadequate. In a lot of cases, it's possible to generate a list of the different things an animal is eating (as in this article on sparkly bat poop), but that doesn't say much about what a specific animal has eaten, in specific amounts, or what nutrients the animal has gotten from the things it has eaten. And the things eaten by a specific animal can vary tremendously. The closest I got was a review that talked about feeding sea lions either squid (low-quality diet) or herring (high-quality diet), and feeding vampire bats either regular blood or diluted blood (Cruz-Neto and Bozinovic 2004 - full references at the end).

One of the insights from that review was that neither the sea lions nor the bats responded to the low-quality foods by upping their intake. This contrasts greatly with what happens in grasshoppers (and crickets, to some extent), who will start to pig out if you give them dilute foods. Grasshoppers are such good eaters that in a lot of cases they can almost completely compensate for differences in nutrient dilution. So, that in and of itself, is interesting, but means that comparisons with the sea lions and vampire bats won't be very helpful except on a very crude level.

...but these insights are not going into the current manuscript, because they're too much of a tangent. Which meant I had to self-redirect and think about the problem from other angles.

The good news is that the people interested in digestive physiology have done much more comparative work that involves detailed examinations of diets than the people interested in metabolism (so far!). So I could find cases where people have found amazingly good and strong associations between the things animals eat and the digestive enzymes they produce.

Anyway, we'll see whether my arguments on that whole front wind up holding water, or whether they wind up getting cut from the paper.

And that was work for one sentence in one paragraph in the Discussion.

Today, I need to spend more time thinking about comparisons between ectotherms versus endotherms. Ectotherms are animals whose body temperature is passively regulated by the environment - things like reptiles, crickets, and grasshoppers, who still behaviorally thermoregulate by basking in the sun. Endotherms are able to generate heat to maintain a core body temperature. One of the coolest endotherms I learned about in Comparative Physiology is tuna fish. Knowing that tuna are endotherms makes it harder for me to ever eat them (on top of knowing that they're long-lived predators and that we're overfishing the oceans like crazy).

Anyway - for my purposes, I think one of the big distinctions I need to highlight between endotherms and ectotherms is that endotherms are able to use "diet-induced thermogenesis" as a regulatory mechanism when feeding on diets with a protein-carbohydrate ratio that is mismatched when compared to their preferred/optimal ratio. A paper (Huang et al) got published in 2013 where researchers fed a group of 279 mice one of 25 diets with different ratios and total amounts of protein, carbohydrate and fat, and then measured their body surface temperature at 25 weeks of age. They found that body surface temperature increased with the total amount of energy consumed, and specifically with amounts of protein, carbohydrate, and fat making similar contributions to temperature based on the kJ eaten.

Previous work has suggested that the mechanisms for diet-induced thermogenesis are best developed in animals adapted to habitually low-protein diets - things like nectar- and fruit-eating bats and marmosets (Stock 1999). But what about ectotherms, like my crickets? Does this all mean that the work in ectotherms can't be meaningfully compared to the work in endotherms?

...and those are the questions to address for today.

These days, I have the following on my plate:

-Postdoc proposal due next Monday. A (mercifully) fairly short application. I don't think my chances are particularly good; the last successful candidates look highly "groomed" for the position. Plus, I don't think I've nailed the question of, "How do I turn myself and my research program into an attractive woman-scientist narrative?" I know women who have. It's not always easy to do, especially when one's research program jumps around a bit and isn't something super-sexy, like birds. It's reminding me of the stupid point during senior year of college when I thought it might be a good idea to apply for a Rhodes scholarship. Actually, much of this year reminds me of that year. Too much stress and flailing about over what the future will hold, and applying for all sorts of things, many of which are unrealistic. I shouldn't be too hard on myself, though, because on the flipside women often get told that they don't apply for enough things. And if I don't apply for things, I can't get things. Anyway. That's that thought process. Easily depressing.

-Respirometry manuscript. Here, too, I'm at that point where the major question is, "How do I clearly articulate why this experiment is groundbreaking and exciting?" Because when I think about it, the experiment provides a good, insightful perspective. It's a stage of narrative construction that I still struggle with.

-"Short-term experiment" This one is a meaty paper. Just not enough hours in the day to work on it.

-The next leafcutter paper. Whenever I think about it, I get excited about this one. I keep getting stuck in data analysis doldrums, but I really need to get this paper submitted and published. The other day, I discovered that my first dissertation chapter has been cited, which is exciting because it means people are interested in it and are reading it. Once I get the next leafcutter paper out, I'll be in a much better position to point to my accomplishments and say, "Hire me/give me money/etc."

Lots of writing. With practice, I hope I can push through the roadblocks more effectively. I know that I know a lot and have a number of valuable skills, but I still wind up rocking back occasionally, wondering about my merit and the folly of trying to make an academic career work, feeling inadequate and stupid about the things I don't know or don't do well.

And it's hard, when I can remember all-too-vividly that fall semester when I had to really live on the edge, and the whole experience of moving out here.
