[Grasper-users] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

[Grasper-users] Question about preparing data

[Josh R. <jro...@ku...>]

I think I have a protocol for getting data from GRASS into a format that
GRASP can handle.  I'd like to see if people agree that it is correct.

I want to predict the range of a species from museum data (presense
only).  

I have a series of environmental raster maps, all with identical
metadata.  

I want to take a site list of known presenses, and use s.sample to get
the environmental data at each site.  A little work with sed and awk
should put the output of those into the right format for the Xs.  A
similar trick should get Xpreds for every site covered by the
environmental data.

The Ys will be the known presenses plus randomly generated
pseudo-absenses.  I'll just generate a sites list that includes
everything but the known presenses, and use s.random to get a reasonable
number of pseudo-absenses.

My questions are: Is this correct and reasonable, and is there an easier
way?  I know there are hooks between GRASS and GRASP, but I don't know
if they can help with data entry.
