Development-induced Displacement in Haiti
In recent decades the people of Haiti have faced ecological disaster, political upheaval, and persis tent economic hardship. These aflictions have motivated hundreds of thousands of Haitians to migrate to other Caribbean countries, the United States and Canada. While many observers know that mass migration was the result of Haiti's problems, it was themass migration from rural highlands to urba...
متن کاملColor - Induced Displacement double stars in SDSS
We report the first successful application of the astrometric color-induced displacement technique (CID, the displacement of the photocenter between different bandpasses due to a varying contribution of differently colored components to the total light), originally proposed by Wielen (1996) for discovering unresolved binary stars. Using the Sloan Digital Sky Survey (SDSS) Data Release 1 with ∼ ...
متن کاملAction can amplify motion-induced illusory displacement
Local motion is known to produce strong illusory displacement in the perceived position of globally static objects. For example, if a dot-cloud or grating drifts to the left within a stationary aperture, the perceived position of the whole aperture will also be shifted to the left. Previously, we used a simple tracking task to demonstrate that active control over the global position of an objec...
متن کاملShear-induced displacement of isotropic-nematic spinodals
The shear dependent location of the isotropic-nematic spinodals in suspensions of bacteriophage fd is studied by means of time resolved birefringence experiments. The hysteresis in the birefringence on increasing and subsequently decreasing the shear-rate allows the determination of the location of points in the shear-rate vs concentration phase diagram between the isotropic-to-nematic and the ...

We report the first successful application of the astrometric color-induced displacement technique (CID, the displacement of the photocenter between different bandpasses due to a varying contribution of differently colored components to the total light), originally proposed by Christy et al. (1983) for discovering unresolved binary stars. Using the Sloan Digital Sky Survey (SDSS) Data Release 2...
