Structural arrangements in the Congress work against the use of analysis, but newer developments, such as growth in staff professionalism and activity of the congressional support agencies, tend to promote it. Interviews with committee staff show that they are aware of much analysis, use it primarily for political advantage, but that they also take it seriously as warning of problems and as guidance on particular issues. Staff value information more when they know and trust its source and understand its political motivations. The use of analysis to reconceptualize problems is not much in evidence, perhaps because such “enlightenment” takes place elsewhere and filters into the Congress through informal channels.  相似文献

For many observers the influx of immigrants into New York's garment industry seemed to exemplify the deleterious impact of undocumented immigration: native displacement and a simultaneous deterioration of wages and working conditions. This article argues that this conventional view is incorrect. There is little evidence linking immigrant presence to the availability of undocumented workers. Rather, the immigrant presence is the consequence of the industry's basic labor strategy; immigrants have moved into garments as an older labor force deriving from earlier waves of migration has cyckd out.  相似文献

Altogether, 318 preliminary proceedings were initiated against physicians, compared to 2 against nonmedical practitioners. The majority i.e., 192 proceedings, dealt with charges of torture and deprivation of freedom committed against patients under psychiatric treatment. Ninety-nine proceedings were based on negligent bodily injury and negligent homicide and 15 on failure to give medical assistance. Other reasons were given in isolated cases only. The proceedings were mostly initiated against surgeons, psychiatrists, general practitioners, internists, gynecologists, and 2 against nonmedical practitioners (42 because of negligent bodily injury and 48 because of negligent homicide). The charges were dropped in accordance with Section 170,2 StPO in 78 cses, Section 153, 153a and 154 StPO in 7 cases, and there were 7 acquittals and 2 sentences after trial. In the remaining preliminary proceedings, the charges were dropped in 215 cases according to Section 170,2 StPO, and in 2 cases according to Section 153a StPO. Three defendants were sentenced to punishment and 1 received a verdict of not guilty. Thus in most of the preliminary proceedings the charges were dropped.  相似文献

The applicability of isoelectric focusing in immobilized pH gradients for the Gc-subtyping in the forensic examination of bloodstains was tested. It is shown that due to the excellent separation of the Gc 1S and 1F bands subtyping of bloodstains can be done with high reliability.  相似文献

Sudden death in a neonate as a result of herpes simplex infection   总被引:1,自引:0,他引:1  
This paper describes a case of a neonate with disseminated herpes simplex born to a 14-year-old asymptomatic mother. The infant's physical examination was normal at birth, and subsequent abnormalities were so subtle that infection was not recognized during life. Postmortem cultures of liver and spleen grew herpes simplex virus, and immunofluorescent direct antibody typing revealed Type 2. A cervical culture of the mother obtained after the infant's death was negative.  相似文献
