UCLA Lecture Videos on Behavior, Evolution and Culture Now Available Online

The UCLA Center of Behavior, Evolution & Culture hosts lectures by top notch scientists working on issues of evolution and the study of human behavior and culture. In the past, I have given BEC lectures as has Dr. Michael Cannon and (I believe) Dr. Hector Neff. These lectures run throughout the academic year and are held on Mondays at UCLA, Haines Hall. They are a great opportunity to view the latest work on the use of evolution as a means for explanation in the social sciences (including anthropology). You can get more information about the upcoming lectures here: http://www.bec.ucla.edu/BECSpeakerSeries.htm

The UCLA BEC center has now started recording these lecturers and putting them on the internet. These videos are put online a bit after each lecture and make a great way of learning about cutting edge research while not having to suffer the commute to/from UCLA. For example:
Caleb Finch 1/5/09 The Role of Diet and Infection in Human Evolution: http://blip.tv/file/1672088
Karthik Panchanathan 1/12/09 Quantifying the Bystander Effect in a Multi-player Dictator Game: http://blip.tv/file/1672132
You can view the set of already recorded lectures at:http://blip.tv/search?q=ucla+bec&x=0&y=0 . The lectures are also available on iTunes U -- Search for "ucla behavior evolution culture".

Evolving Thoughts: The ontology of biology 4 - pattern and process

Today's blog from John Wilkins demonstrates that he gets the phenomenological/ideational distinction and its implication for biology - Evolving Thoughts: The ontology of biology 4 - pattern and process] The addition of some ontological schemes might contribute to his pondering about where ontology comes from... perhaps some Sellars would do the trick.

Geography, Archaeology and the iPhone

In many ways, the 3G version of the iPhone has the potential to be a great little device for field data collection. The iPhone boasts a GPS, a digital camera a great buttonless interface, sharp graphics, integration with Google Earth and a remarkable programming SDK. Yeah, there are downsides: the precision of the GPS is probably ca. 5 meters at best, the camera CCD "only" 2 megapixels, the SDK is available only through a developers program, the 3G data plan will bankrupt most people if used internationally in "data roaming" mode. But compared with the expensive, heft and "special purpose" nature of most professional gps/data collectors - the iPhone is kind of the ultimate in tiny, ubiquitous, multi-functional and inexpensive field device since one can:

- take geotagged photos of landscapes/artifacts/objects

- record notes for positions through a host of applications.

- locate oneself on satellite imagery and aerial photography - live and in the field!

- perform functions such as calculate slope, measure remote heights through 3rd-party apps

- potentially develop specialized GIS field data collection apps using the SDK (which has a SQL dimension) in which one can photograph features, record positions and describe things using a pre-set data dictionary.

- not to mention it's a phone.

I think that some of the potential for the iPhone is just beginning to emerge as developers find out about the possibilities of this platform and GIS users realize what they have in their pockets. As it stands there are a number of good applications that point in the direction that the iPhone platform can go in terms of GIS functions. For reference sake here are a list of apps that I have come across to date. There are many others - if you have any good ones, let me know.

- Google Earth (of course). This iphone app makes viewing and collecting points on real-time imagery possible.

- TrackMe a 99 cent app that is great for mapping linear features and tracks.

- iPhone Maps - this is a built-in application but is fairly useful for plotting locations. Quite basic but functional.

- GPK Kit - This is a comerical app ($10) but a good one for turning your iPhone into a functional GPS unit with all the features you'd expect.

- SeaDragon Mobile - This Microsoft iPhone app showcases their "Deep Zoom" technology - but also hosts their Virtual Earth imagery (with GPS locations) as well as Photosynth! Whoohoo!

- Cardinal Application is good for working out direction (eg: orientation of slope, direction of flow of a river etc…)

- Clinometer Application – Slope, angle and gradient measurements on demand

- RulerPhone - lets you measure remote objects (or artifacts) by including a fixed scale in the image. With this one could measure heights of trees, mounds, or sizes of artifacts.

- Geotags - Is a basic GIS app for the iPhone. It allows you to take geotagged photographs, write notes, pinpoint features, and geotag audio recordings. This app demonstrates what will be possible for the iPhone is a basically a generic GIS data recording system.

- AirMe is a good application for automatically uploading geotagged photographs to Flickr.
