Ideology and policy research are intertwined in many ways; an example is Murray's Losing Ground which uses “science” to justify racial, sexual, and class discrimination. Murray is utterly faithful to the neoconservative version of how liberalism went wrong in the 1960s. He says an intellectual elite shifted the blame for poverty, crime and low achievement to “the system” destroying individual responsibility. But his argument is not supported by evidence. Data are bent tofit foregone conclusions. He argues that more people are becoming dependent on government support, but his method of counting who receives assistance is a fiction. Nevertheless his argument has wide appeal among Americans. Why? His argument touches the self-interested Social Darwinist in almost all of us.  相似文献

Decomposition of buried bodies and methods that may aid in their location   总被引:5,自引:0,他引:5  
This is the second report on an ongoing study conducted to collect data on the decompositional rates of human cadavers and the first on buried cadavers. Six unembalmed human cadavers were buried separately in unlined trenches of various depths and allowed to naturally decompose for a time period ranging from a month to a year. During the period of burial, data were collected daily on the air, soil, and cadaver temperature at each burial site. At the end of each specified burial period the cadavers were exhumed and examined for the degree of decomposition which had taken place as well as changes in the soil pH, surface vegetation, and carrion insect activity. Analysis of the data shows that the decomposition rate of buried cadavers is highly dependent on the depth of burial and environmental temperatures. The depth at which the cadaver was buried also directly affected the degree of soil and vegetational changes as well as access by carrion insects. Application of this information can contribute to a more accurate estimation of time since death of a buried corpse and may aid in the location of such corpses.  相似文献

Healthy male volunteers drank neat whisky in amounts corresponding to 0.51, 0.68, or 0.85 g ethanol/kg body weight in 15-25 min after an overnight (10 h) fast. Urine was collected immediately before drinking and then at 60 min intervals for 7-8 h after intake. The volumes of urine voided were measured and the concentrations of alcohol (UAC) were determined by an enzymatic method. Ethanol-induced diuresis showed large inter-subject variations. The flow of urine was maximum between 60 and 120 min post-drinking when the median rates of production were 117 ml/h (range 55-335), 113 ml/h (range 41-453) and 373 ml/h (range 215-485) for 0.51, 0.68, and 0.85 g ethanol/kg respectively. The output of urine returned to normal (30-60 ml/h) after the peak UAC had passed despite an elevated blood alcohol concentration (BAC). The average amount of alcohol excreted in urine was 0.29 g (S.D. 0.119), 0.44 g (S.D. 0.246), and 1.00 g (S.D. 0.427) after the consumption of 0.51, 0.68 and 0.85 g ethanol/kg respectively. Neither peak diuresis nor the amount of alcohol excreted depended on a subject's age between 20 and 60 years. This work shows that after drinking a moderate dose of alcohol, only 0.7-1.5% of the amount consumed is excreted unchanged in urine. Ethanol-induced diuresis is most pronounced for the first 1-2 h after drinking (rising BAC). The production of urine returns to normal during the post-absorptive state.  相似文献

Hanging: suicide or homicide?   总被引:1,自引:0,他引:1  
Death by Hanging: Suicide or Homicide. Six cases of homicidal hanging and murder presented as suicidal hanging are recorded. Suspension followed strangulation by ligature or throttling and head injuries in 4 cases. Distinction between homicide and suicide was easy in 5 cases: two of the perpetrators gave themselves up to the police, one committed suicide immediately after he had hanged his 15 year old daughter; in two cases tracks of blood, heavy injuries of the victims, and traces of robbery were obvious. Unless the victim is an infant or an adult person incapacitated by drink, disease, or drugs, or unless there are several assailants murder is difficult to accomplish. Distinction between murder and suicide may be impossible by an examination of the body alone. Detailed investigation of the scene, reconstruction of the position of the suspended body, examination of the rope, the knots, the direction of the fibres on the rope may serve to discover homicidal hanging. - Compared to suicidal hanging homicide has a frequency of about 1% in our autopsy material. However, we cannot estimate the number of obscure cases.  相似文献
