Still Left in the Dark : The Confrontation Clause and Child Abuse Cases After Davis v. Washington

In his concurring opinion in Crawford v. Washington, Chief Justice Rehnquist criticized the majority for holding that the Confrontation Clause applies to “testimonial” statements but leaving for “another day” any effort to define sufficiently what “testimonial” means. Prosecutors and defendants, he said, “should not be left in the dark in this manner.” Over the next two years, both sides grappled with the meaning of testimonial, each gleaning import from sections of Crawford that seemingly proved their test was the right one. When the Court granted certiorari in Davis v. Washington and Hammon v. Indiana (hereinafter Davis), hopes were high that the Court would provide the answers—the definitive test for testimonial. Not surprisingly, it did not

The Effect of Dissolved Polyunsaturated Aldehydes on Microzooplankton Growth Rates in the Chesapeake Bay and Atlantic Coastal Waters

Allelopathy is wide spread among marine phytoplankton, including diatoms, which can produce cytotoxic secondary metabolites such as polyunsaturated aldehydes (PUA). Most studies on diatom-produced PUA have been dedicated to their inhibitory effects on reproduction and development of marine invertebrates. However, little information exists on their impact on key herbivores in the ocean, microzooplankton. This study examined the effects of dissolved 2E,4E-octadienal and 2E,4E-heptadienal on the growth rates of natural ciliate and dinoflagellate populations in the Chesapeake Bay and the coastal Atlantic waters. The overall effect of PUA on microzooplankton growth was negative, especially at the higher concentrations, but there were pronounced differences in response among common planktonic species. For example, the growth of Codonella sp., Leegaardiella sol, Prorodon sp., and Gyrodinium spirale was impaired at 2 nM, whereas Strombidium conicum, Cyclotrichium gigas, and Gymnodinium sp. were not affected even at 20 nM. These results indicate that PUA can induce changes in microzooplankton dynamics and species composition

Oblique incidence and observation electronic speckle-pattern interferometry

In this paper we discuss an oblique incidence and observation electronic speckle-pattern interferometer, in which we use an anamorphic prism in front of the object. A collimated beam traveling through the prism is partly reflected at the base of the prism. The reflected light is the reference beam and the transmitted light illuminates the diffuse object, thereby generating the object beam. In this scheme the object and the reference beams are collinear. A new scheme that uses two prisms and permits phase stepping is also presented
