I will be out of town 4/14 to 4/18, which makes all harder (Thurssday to
Friday).   Perhaps you might be able to run one then?

=20

As for the deeper question  of "should Sean consider use of dSUrvey".
Basically, it is a fairly powerful, moderately tested tool - but it is
idiosyncratic. =20

Here are some thoughts.

I will note that using it has one advantage: I am more than willing to
help AND to modify if needed features are missing.

=20

A discussion of strengths and weaknesses of dSurvey

=20

=20

A advantage of "dSurvey" is that it is fully webbed. Which means,
conceivably, you can run an experiment from anywhere-all you need are
computers with web access.

A disadvantage of "dSurvey"  is that it is fully webbed. Which means
that if one's connections are slow, or if the distant server has
problems, you are SOL.

=20

An advantage of "dSurvey"  is its use of an XHTML syntax to specify
screens, which includes extensions (tag names) that make it fairly easy
to specify dynamic content (content whose value depends on participant
specific data and on data that changes over the course of time). And
this specification requires little or no understanding of how
client-server communications are structured.

=20

A disadvantage of "dSurvey" is its use of a "proprietary" XHTML syntax,
one that is more-or-less unique to "dSurvey". This means the instrument
designer must learn a unique syntax, for which there are not readily
available GUI tools. In other words, one must hand code the content
(although starting with a good HTML editor and tweaking it afterwards
might work. Note that dSurvey does include some tools to help program
its various components, but they are fairly primitive.

=20

An advantage of "dSurvey" is it use of javascript. This means that
results calculations can be programmed in a well known language.
Furthermore, a number of functions are provided that make it relatively
easy to retrieve and save parameters (including participant specific
parameters), data submitted by participants, and the results of prior
calculations. And it is straightforward to communicate the results of
these calculations to participants and to the administrator

=20

A disadvantage of "dSurvey" is its dependence on javascript to do
serious calculations. Some calculations can be done by dSurvey's built
in features, but for anything slightly complex the easiest approach is
to use javascript functions created by the instrument designer.  While
use of external software (i.e. excel) is supported, it requires a
moderately convoluted approach (saving data, running the external
software,  reading the data, further processing of the data).  Thus,
effective use of dSurvey is enhanced by a familiarity with javascript.

 =20

An advantage of "dSurvey" is it use client-centric structure.  The broad
outline of a survey session is specified in XML "specification files"
that allow for a dynamic set of treatments (that can be changed
mid-session).  This reduces server load, and provides a moderately
intuitive structured mechanism.

A disadvantage of "dSurvey" is it use of a proprietary means of
specifying how treatments are presented.  Itsa XML "specification files"
requires hand-coding, as there are no style sheets  (XSLT) or schema to
validate or otherwise assist in their design.  While providing
flexibility, the syntax of these specification files is unique to
dSurvey

Hi Dan,

Yes - a busy April indeed.  I have already started to recruit for next
week.  Shooting for 4pm on Tues or Wed (both if we have enough interest
- I'm doubtful, but will keep you posted). =20

I am certainly serious about wanting to learn the software. Next year, I
would like to run some lab experiments in China as part (or in addition
to) my dissertation research (deals with performance pay/provider
incentives in health care).  In fact, I had just started to look into
z-tree.  I can't invest the time to learn all of the inner workings, but
I would like to learn to set up and tweak instruments. After I play with
it a bit over the weekend, it would be great if you could answer
questions before a session next week if you have the time.

Best,

Sean

Alas, we will have a busy April.  This kind of  delay is  what worries
me --- which is why I will err on the side of being a pest.=20

Which is to say : if you can setup a session for next week - EXCELLENT.
Any day but Thursday. And preferably in the afternoon (4pm or later).

And for this next session, grad students are okay (even repeats).=20

=20

=20

---

If you are serious about learning the software, I don't mind making a
special trip. But if you aren't that serious, eh.

=20

With this in mind: if you want to play with it, the url is

=20

http://survey.arec.umd.edu/dsurvey/admin.htm

=20

The first thing to do is to "create a survey session".  You will then be
asked to select an instrument - the one I am using is the "TICKETS"
instrument

under the "ERS" project.  After a couple of steps, which are more or
less obvious, you will be shown a control-panel.  I am going to say no
more and see if you can figure  out what the next steps are by using the
hints embedded in the control-panel  (i.e.; look at the "suggestion"
link near the top of the screen).=20

=20

I will say that you can   open up  one (or more) "participant" screens
(each under a new window or tab, obviously) using the  "join a session"
link on the admin.htm page=20

=20

Once you have a control-panel (the session administrator) and one or
more 'participant' screens, you can then simulate a session.  Lots of

options!

=20

BTW: you must use Firefox, or Chrome, or some other such NON-IE browser.
IE's javascript support is flakey, and I haven't ironed out all the bugs

that IE introduces.

=20

If you decide to play around, take some notes of where you are confused!
This will help me identify the most important stuff to document, etc.

=20

BTW: if you want to be ambitious, there is a lot of documentation
describing how to create instruments, etc - see the "documentation" link

at the top of the admin.htm screen.  And if you for some reason want to
create your own instrument, I am more than willing to help - I just ask
that you try using the documentation (I need beta testers!)

=20

One word of caution: I am constantly tweakihng the design (I.e; I am
just about to add a "run-time parameters" option to the "scenarios". So
don't get to wierded out if the look and feel changes.

Hi Dan,

Unfortunately, it does not look like we will make it to 8 for Friday.
But, I do think we can get a decent number of session in before the end
of the semester. I'll do my best to make sure we can hit the ground
running when the students get back from spring break.  Hopefully, we can
get access to the list soon.  I'll also see about recruiting by some
other means.

I would like to learn more about the software, but you don't need to
make a special trip up here.  I'd also like to have a chance to play
with it some before hand.  Maybe you can come up an hour or two before
one fo the sessions?

Best,

Sean

Hi Dan,

The response from the solicitation was not overwhelming...3 yes, 1
maybe, 1 yes, but previously participated.  Right now, I'm resorting to
direct requests, but this is probably not great if you want to use the
data...Let me know if you want to go ahead with these. If not, we can
just start a full-on charge after spring break.

Sounds good - as long as you don't think I have already tainted the
sample by suggesting this was a pretest. Do you want exactly 10? Even
number?  Also, I'm assuming you do not want to use those who have
already participated...

I agree that we should get moving on the undergrads (especially if you
think you might want more than 3 sessions), but would not be too worried
since we still have 6 weeks or so till finals.  We'll try to get this
going ASAP.  If we get access to the list soon, I can try to recruit for
next week.=20

Try to get a full 10 students, and we maybe we I can use this (with

But ASAP we should start doing the undergrads.  Maybe maybe we can get
enough next week. Iif not, the week of 3/27 to 4/1, we should try to do
2 or 3, any day but Wednesday.

I fear running out of time - much past May 1 becomes problematic with

Hi Dan,

Sorry... I thought that you just wanted to test the software/procedures
again. Unfortunately, the prof who controls the recruitment list of
undergrads has not gotten back to me (I sent an email last week - having

If you do not want to run with grad students again, I can rescind...not

I should have been clearer - I think we should push forward with a  more

toss the data.  =20

=20

It's too late to rescind your grad student invite, but why not also send
a note to the normal recruitment list.

And I will treat this as a serious experiment (if gradstuds want to
comment AFTERWARDS, okay... but otherwise normal experiment rules
apply).

On second thought, would you be able to come on Friday?  I just realized
that next week is spring break here so there may not be many people in
the department.  I'll see how the numbers would look on Friday and if
there are not that many that can participate, we may need to wait until
the week after next. =20
