This study examines the unfair trade decisions of the InternationalTrade Commission (ITC) and how they have been affected by Congress.It begins by identifying the means Congress can use to influenceITC decisions and then estimates both the extent to which thesemeans have been used and the extent to which they have shaped theITC's behavior. The study reaches two conclusions. First, Congresshas tried to shape the ITC's behavior, but it has not tried tomicromanage this behavior. Second, while the ITC's behavior hasbeen influenced by Congress, congressional influence is not asimportant as other factors, such as statutory criteria.  相似文献

A simple and rapid method is described for processing organ and water samples for the identification of diatoms so that they can be studied and recorded for taxonomic and diagnostic purposes. Samples are treated with concentrated nitric acid; the fluid obtained is centrifuged, and its sediment is dried, coated, and examined under the scanning electron microscope. The method does not alter the morphology of diatoms and allows the study of freshwater and seawater species present in the organs of bodies found in the water, making possible the diagnosis of drowning under specific conditions.  相似文献

Criminal justice agencies are organized sequentially — “output” from one agency is “input” to the next — but most scholars argue that criminal justice is not a system in a theoretical sense. In this article, it is argued that general systems theory (GST) reveals important insights into criminal justice structures and functions. Specifically, it is argued that the criminal justice system processes “cases” rather than people, and that the common goal of criminal justice processing is to “close cases so that they stay closed.” It also is argued that processing capacity progressively declines, in that at each system point the subsequent agency cannot input as many cases as the previous agency can output. Each agency therefore experiences “backward pressure” to close cases in order to reduce input to the next agency. Overall, this article highlights that criminal justice agents and agencies are best understood as operating in the context of the larger whole, thus it is concluded that criminal justice is a system in the sense of general systems theory.  相似文献
