经济宪法学立足于保障个人财产权和限制政府权力,从而为矫正市场失灵和政府失灵提供了新的、也是更为根本性的思路,这就是必须从宪法上明确对个人财产权和经济自由的保护,并严格限制政府的财政权和货币发行权,使政府的自由裁量权置于民主监督之下。  相似文献

Data on bone tissue fractography are summarized and systematized. Possibilities of a microscopic fractography method in analysis of skeletal bone fractures in order to determine conditions of traumatic exposure were shown. Destruction of bone tissue is considered from the point of view of fragile and tough destruction using as a model solid body with crack at the top of which deformations of detachment, lateral and longitudinal shifts are acting. Morphologic features for different types of destruction were singled out. Use of these features may help to determine character and type of deformation at concrete areas of fracture during all destruction process.  相似文献

Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce.  相似文献

From a conflict resolution perspective, it is clear why the child support guidelines are not going to reduce the adequacy and compliance gaps in child support payment conflicts between parents. As it stands, the conflict over equally sharing child support is destructive rather than positive. The guidelines do not reframe the conflict for the parents, enabling them to believe the interests of children are more important than their own interests to win the child support battle. To transform conflict from destructive to positive, the elements of conflict–expression of the conflict, scarce resources and rewards, and interdependency–must be transformed. It is argued that the guidelines do not transform the conflict but facilitate it. Courts and attorneys are also significant players in the child support conflict.  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

Archibald T. Strong, born in Melbourne, was the son of an Australian scholar who went to an academic post at Liverpool. The younger Strong received his secondary and tertiary education in England. There, he became proficient in modern European languages and literature. He initially planned a career in the law, but for health reasons returned to Australia to the Department of English at the University of Melbourne. Prior to the First World War, Strong became prominent in Melbourne literary circles and also a prolific commentator on world affairs. As an early member of the Round Table group in Australia, Strong assessed Imperial Germany as posing an existential threat to the British Empire and hence to Australia's security. The nation's future, he believed, lay in unwavering defence of the Empire. Strong evinced a distinct impatience with fellow citizens, especially on the socialist left, who failed, in his view, to understand the realities of Australia's position in the world and what was at stake in the Great War.  相似文献
