Hyperbolic discounting emerges from the scalar property of interval timing

June 7th, 2011

Ten dollars today is more attractive than the same amount of money tomorrow and is consistent with the well known proverb, “a bird in the hand is worth two in the bush”. We all know that the value of a reward is discounted over time. How the value discounts over time and what is the rationale for such discounting, however, is less clear. Here is my version of explanation.

How to create TIFF files

November 13th, 2009

When you submit a manuscript, many journals ask you to send your figures in TIFF format with some requirements such as 300dpi, flattened, LZW compressed, etc. How to do that?

My figures are usually finalized in MS PowerPoint. I don’t use PowerPoint’s own “save image as …”  b/c it’s not flexible. I use Adobe Photoshop.

  1. Group and copy the figure in PowerPoint
  2. Launch PhotoShop, File | New to create a new image. Don’t forget to set Resolution to 300 pixels/inch (dpi). Background is white. Then click OK.
  3. Paste your figure.
  4. (optional) do some cropping, trimming …
  5. File | Save As, select “TIFF” as saving format; uncheck “Layers” (i.e. flatten your figure), click Save
  6. Check “LZW” compression
  7. OK.
