Aside: Marissa Mayer, Yahoo!, and being pretty annoying
If you have one hour of your time sitting there for you, and going to beach, playing with your kids, drink something etc. does not seem a good option, I recommend this Business Insider's article on Marissa Mayer. Super-driven, clearly very smart, so far her Yahoo! tenure has been a huge success (but read how Alibaba must be partially responsible), but there is a but. Quite a few buts, actually. Would I enjoy working under her? Not at all. Always late, she tries to out-talk you, very often she cancels one-on-one meeting without previous notice and no justifications, makes people wait for her forever, no social skills, she says that raising baby is easy when she has an army of helpers, nannies, a $5 million penthouse, come on.
"Mayer had approximately 25 people reporting directly to her during her first year at Yahoo. In theory, she was keeping up with each of them in a regularly scheduled weekly meeting. In practice, she would go weeks without talking to people because she was so busy.
For a while, each of those 25 people thought that Mayer was just picking on them, individually. The people who had been at Yahoo before Mayer joined assumed that this meant she was going to fire them soon. The people Mayer had just hired into the company, including Reses and Savitt, were even more puzzled. Why had they been hired only to be ignored?"
I like analytical people, I don't enjoy that much the "slap in the back" attitude, especially when I am on the receiving side of slapping, I am all for talking shop up to 2am and getting back at it after 3 hours of sleep, but cancelling appointments like the other guy is worth neither your "I am sorry" nor some kind of explanation, having open office hours like you are an high school teacher, well, I think I'd last 10 minutes. A lot of people left Yahoo! after she got the CEO position, and apart from business and personality clashes inevitably happening at that level, a lot of decent people I believe simply couldn't put up with the disrespectful behavior and attitude.
I do not believe there are "success" lessons in the Mayer's story. Luck makes a huge difference in people's lives and thinking that the road to work or business success can be algorithmically explained or predicted is naive at best. Smart, hard working, brilliant people are on average (and there is a threshold effect for some of those traits, simply people who are not smart in a loose and broad sense are very unlikely to be successful, although we often associate smartness to quantitative and mathematical skills and intuition, and it is quite limiting) more likely to succeed than less smart, less brilliant and lazier people, but beyond that everything is really context-specific and hugely dependent on being at the right place at the right time. Looking at success stories backwards sometimes gives clues, a lot of times doing that is very misleading. The Success Equation is a good read here.
The article, although quite verbose at times, gives a solid and interesting picture of how business deals (including getting a new CEO on board at Yahoo!) are made at the highest level. Very interesting and highly recommended.

ESEB meeting recap
The ESEB meeting left me quite satisfied, although the proportion of talks I really liked was probably ~ 1 out of 5. I think that the submission of abstract 6 months in advance is partially responsible of some sub-par talks. Some of the talks were about papers that I already read and were published in 2012 or in early 2013 and I do not see the point of listening to a talk about a paper I already read. Some of the talks were about ideas only partially developed, and you could tell it.
The plenary by Trudy Mackay about the genotype-phenotype mapping in Drosophila made me think pretty hard. If in a model (the model) species like Drosophila (with more ~ 200 inbred lines) predictions at the individual level for polygenic traits using SNPs are far from being acceptable (she vigorously supports the idea that epistatic interactions are responsible from the lack of predictive ability from simple additivity), do we have any chance of making right now or in the foreseeable future half-decent predictions for polygenic traits in non-model species? We are very far from it, although Craig Primmer was able to predict correctly 8 out of 10 times the age at sexual maturity in Atlantic salmon using SNPs outliers from a GWAS association study.

What I am reading
The Sports Gene by Epstein
As a guy who has been involved in sports all his life, I am as certain as a scientist can be (that is, not 100%, but very close) that there are intrinsic differences in sports abilities. It is not only the early environment, not only the social environment, not only motivation or grit or persistence (which, by the way, as behavioral traits should be heritable. That means that there is an "environmental" and a "genetic" component). Looking forward to reading this book.
On getting more efficient - part 1
I thought a lot lately about how to get more efficient at what I do (I hate wasting time and getting side-tracked), and I am going to write a series of posts presenting my workflow, find tons of holes in it as well as finding/testing way to get more efficient.
One of most compelling reasons to go to meetings and workshop is to take some time off from your routine, listening to some folks and get encouraged or discouraged or neutral, try to convince people that your way is the way, and think about what you can do to improve (in a broad sense) your research program, which ends up most of the times to find better and easiest way to publish in top journals and getting cited a lot. No solving world problems or getting a profit here.
I am right now working on 3 model systems (if I remember well, hint: problem), many different topics within the same model systems (including theory), and I expect things to get messier quite soon when I will get the genetic data from marble trout (a month or two, the sequencer just arrived at the lab). I am not teaching and I am quite limited administrative work. Two group meetings a week lasting 1 to 2.5 hrs each. (At least) Part of the weekend (almost always) on.
I am satisfied by my production of ideas and code on a daily basis, including writing a blog post around 5am in a Lisbon hotel because I am jet lagged. I typically work on a one or two model systems a day with a switch that gets quite "formal" most of the time (e.g. I open another workspace in R), and within the same system I typically in a single day on one or two problems. For example, I may work in the same day on kittiwakes (1st model system) and on marble trout (2nd model system). For kittiwakes, I might work on testing measures of growth variability and their effects on survival and reproduction, and for marble trout I might work on estimating the repeatability of body size and on estimating the standard error of parameters on the random effect effect model of growth I am currently working on (2 problems). Plus, for each model system/problem, I typically produce an amazing number of plots, since I am very keen on visual communication to myself and other people. Should I focus on one single problem a day/a week, the same problem for the model system each day/week until solved and ready to get shipped? Or more interesting/fun to work on many problems/model systems at the same time trusting your supernatural abilities of concentration while worrying about the fact that things very clear right now are clear a mud next week (advice to myself: comment code a lot more)?
On Time and Making Figures
How long does it take to make this graph (click to enlarge)?
Yesterday it took one hour and a half. I used the R package ggplot2, which allows for a greater control on all the various plot components, from legend, to points, to lines, than the standard plot libraries (ggplot2 is great and a good fun, by the way). However, ggplot2 is is very verbose and not intuitive (at least for me). Plot quality is very nice, though. The figure above is one of the figures in the soon-to-be-submitted paper on a novel approach to estimate individual variation in biological processes, in this case body growth of fish using the von Bertalanffy growth function (I will explain how the two parameters are positively correlated in a later post). Top row is one fish populations, and bottom row another one.
Anyway, is one hour and a half too much for a single figure? Consider that I am quite skilled with graphs (even if I could not delete the annoying diagonal line in the legends of the density plots - Illustrator will help -, and I still don't know whether is better to use common y-and x-scales for the two populations) and I don't waste much time (I am quite the perfectionist, that's the only problem). I don't know, Hans and I have worked for quite a long time on the process model (in weeks, not in hours), so maybe this is time well spent, even it takes time from doing some more "important" stuff (like actually solving problems, same thing for writing this blog post now that i think about it).
