Hans Larsson and I had our paper published recently in PNAS on the low beta diversity of Maastrichtian dinosaurs in the Western Interior. Hopefully a few people will read the methods and notice that we used the fossil package to do a lot of the stats in it, and others might start using it as well. If you have any questions about the paper or the package, feel free to contact me any time.

Teaching
March 11, 2010 · Leave a Comment
I have been reading a bunch of articles lately on education, and how to improve it. It’s been making me think a lot about my own education, especially in university. I just want to know if the major universities are ever going to give education more than a fleeting thought. Obviously, research is very important, but at what point should it be to the exclusion of teaching? If you never take the time to teach others what you know, then what? Knowledge not passed along is knowledge lost. I would hate to have toiled away at my research, uncovering new things, but not have shared that with others before I died. And I mean more than what can be passed along in a journal article. Too many journal articles are never read anyhow; if you actually take the time to teach someone what you know, then you know that knowledge will have been passed on. And when I talk about teaching, I mean more than just standing in front of a room and saying words. There was a class in university that I went to less than half the time, and I did better for it because I didn’t get confused by the abysmal teacher reading nothing but equations off a Powerpoint slide. I think that too often, profs forget that the people they are teaching could become some of the most important people in their lives: namely, politicians. If these future politicians (and their constituents) a never taught how exciting or amazing a subject is, that subject might not get as much funding the next year, because nobody cares about it. Teaching can be in your own self interests.

fossil Package Updated to 0.2.4
January 20, 2010 · Leave a Comment
I just uploaded a new version of fossil to the CRAN website, with a number of changes. There are some fixes in the way the spp.est() function was handling abundance data, and I’ve added a small species/locality dataset that I used for a number of new examples in the package. I’m also currently working on a new clustering method to include, but it’s still being worked on at the moment. Hopefully it’ll be in the package before too long.
Enjoy!

LaTeX and Palaeontologia Electronica
January 18, 2010 · Leave a Comment
I’ve been trying to prepare a manuscript for submission to Palaeontologia Electronica (PE), and as my workflow at the moment has been revolving around LaTeX, I took te plunge into creating my own custom bibliography style file in PE format. Luckily for me I could use the great makebst.tex file by Patrick W. Daly which simplified the process to a series of multiple choice questions. I somehow doubt that there is that many other palaeontologists using LaTeX for manuscript submissions, but anyhow here’s the palelec.bst file (I can’t upload .bst files to this site, so just copy and save the text in a text editor as palelec.bst). Hopefully it works, as I’ve been fighting a bit with WordPress to get it to render properly, but if need be, you can always contact me and I can send out a copy of the original .bst file.

% This bibliography style file is intended for texts in ENGLISH
% This is an author-year citation style bibliography. As such, it is
% non-standard LaTeX, and requires a special package file to function properly.
% Such a package is natbib.sty by Patrick W. Daly
% The form of the \bibitem entries is
% \bibitem[Jones et al.(1990)]{key}...
% \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
% The essential feature is that the label (the part in brackets) consists
% of the author names, as they should appear in the citation, with the year
% in parentheses following. There must be no space before the opening
% parenthesis!
% With natbib v5.3, a full list of authors may also follow the year.
% In natbib.sty, it is possible to define the type of enclosures that is
% really wanted (brackets or parentheses), but in either case, there must
% be parentheses in the label.
% The \cite command functions as follows:
% \citet{key} ==>> Jones et al. (1990)
% \citet*{key} ==>> Jones, Baker, and Smith (1990)
% \citep{key} ==>> (Jones et al., 1990)
% \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
% \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
% \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
% \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., 1990, p. 32)
% \citeauthor{key} ==>> Jones et al.
% \citeauthor*{key} ==>> Jones, Baker, and Smith
% \citeyear{key} ==>> 1990

Reproducible Results: Not Likely
September 22, 2009 · Leave a Comment
A PLoS article this week puts some numbers (small, though they may be) on how truly free and open scientists are in sharing their data. For the article, the authors sent information requests for data previously published on in PLoS journals. The thing about these journals is that they have an explicit data sharing policy, which makes it clear that the raw data sets they use in their analyses must be made available to other researchers.
Just a little history about the PLoS journals: they were originally set up with the ideal of Open Access as a founding tenet. This included not only sharing your data but making the journal itself freely accessible to anyone, free of subscription.
But back to the article itself. THe authors found that out of 10 requests for data, they recieved only one dataset. In fact, some of the data holders seemed rather indignant in the thought that someone might actually want to look at THEIR data, as I’m sure they thought the only reason why would be for the requesters to scoop the next big story to come out of these datasets.
In the end, this study only really serves to emphasize the fact that science is still a very closed (and I would say, closeminded) place to work in.

Evolution Essentials
September 20, 2009 · Leave a Comment
A great summary on Ars Technica about 5 essential things that most people don’t understand about evolution. It’s a good read even if you do think you know a lot about evolution, as it emphasizes some points that I think are often muddled in a lot of scientific discussions (subobtimal solutions being better than no solution, for example).

Patented Phylogenetics
September 13, 2009 · Leave a Comment
Ars Technica has a story about how Microsoft tried to patent clustering phylogenetic methods. If the patent would have gone through, it could have meant that anyone who wanted to use a phylogenetics clustering program (PAUP, Mesquite, etc) would have suddenly found themselves unable to do so, at least not without paying Microsoft first the associated fees for licensing their patent (or else by pirating the software, which seems to be a common theme in cash strapped labs). Luckily, there is plenty of prior art (meaning, Microsoft was obviously not the first person to do it), so they won’t be granted the patent in the end. Something like this makes an (arguably) good case for scientists to release any code and programs they produce under an Open Source license, which in effect would preserve their work in the public domain for future scientists to use.

Creationism 2.0
September 11, 2009 · Leave a Comment
If you happen to take William Dembski’s course on ‘Intellient Design’ at Southwestern Baptist Theological Seminary, you will be pleased to know that you can get an easy 20% of your mark from simply posting replies defending creationism ‘Intelligent Design’ on ‘hostile’ websites (presumably, that means ANY scientific website). Richard Dawkins (who is very intelligent while simultaneously arrogant, or at least so he seemed from the talk I saw) mentions this as well as plucking out some other gems from the course, such as a question from the Christian Faith and Science module which reads:
Trace the connections between Darwinian evolution, eugenics, abortion, infanticide, and euthanasia. Why are materialists so ready to embrace these as a package deal? What view of humanity and reality is required to resist them?
Remember kids: don’t evolve.

Zombie Defense: Strike Hard, Strike Often
August 16, 2009 · Leave a Comment
Most people should remember from elementary school how we were supposed to create a fire escape plan for our house and practise it with our families, but what about other equally dangerous and deadly situations? I always found my school lacking in it’s zombie plague contingency plans; luckily we now have a better idea of a plan of action. Four students from Carleton and University of Ottawa have run different outbreak and response models (PDF) for zombie infection. Unfortunately, the news is not great. Only one scenario works in favour of non-zombies, that of a strike hard and strike often approach. Even at that, the authors are not entirely convinced the plan would be successful, especially as coordinating attacks during a time of turmoil would be very difficult. So remember to be on the lookout for zombies at all times, as the earlier the infection is caught, the more likely the human race may survive.

Death of the Dead Tree Journal
August 15, 2009 · Leave a Comment
Ars Technica has a story on the American Chemical Society and their plans for switching most of their journals over to electronic format only. In some ways, the news may seem surprising, but at the same time, it does seem somewhat inevitable. I know that personally I do virtually all of my research online in some fashion. Anymore, if the article isn’t online and isn’t that vital to the work I’m doing, I’m not going to waste my time tracking it down when there are likely other papers that will work as well and are online, and I think this kind of attitude is (for better or worse) fairly common among my generation in the sciences. The days of the printed article are likely numbered. This is not to say that books will stop being published, but I see books (and by this I mean something I read for enjoyment) and journals (something I read for my job) as two different things. Journal articles are more useful to me if they are electronic, as then I can have them instantly in front of me without having to search through a filing cabinet, I don’t have the clutter of papers that I print of to skim once and never use again, and I can search with various tools to find what I want even if I can’t remember the specific paper. Books, on the other hand, I want to be able to enjoy slower and away from the distractions of a computer. I don’t need to search the text of a book and I like taking them to places where I have no power source, such as the park or camping. Books are more useful to me in dead tree format, and I will continue to buy them in that format. But I can honestly say that so long as I can access journals on line in high quality PDF format, that I won’t miss the fact that they’re no longer being printed. In fact, not printing them means lower costs for me in a couple of ways: research libraries no longer need to spend money building larger and larger buildings to hold journal collections that are rarely looked at; and (hopefully) journal subscription costs come down because of the savings of not having to pay for printing. Let the future begin.
