Determination of ABO-blood group on human hair segments of 79 individuals was performed by means of modified Yada absorption-elutions technique. The studies were carried out with 4 micron thin cross sections of hair. In 79% of the cases it was possible to establish the correct blood group. Individual hair segments of 0.5 cm length yielded reliable results. Antigen identification was best with blood group B and most difficult of the AB type. 相似文献

The concept of integrated care has assumed growing importance on the policy agendas both in England and The Netherlands and elsewhere. It is characterized as health and health care-related social care needed by patients with multi-faceted needs. This article compares policy approaches to integrated care in England and The Netherlands. Differing political strategies and conditions for integrated care correspond to the dissimilarities in the institutional structure and culture of their health care systems. Health care systems are understood as specific national and historical configurations. We review the last decade's relevant policy processes, using the concepts of hierarchy, market and network. The state health care system in England relies mainly on hierarchical steering, thus creating tight network structures for integrated care on the local level. The Netherlands, with its health care system in a public-private mix, has set incentives for voluntary, loosely coupled and partly market-driven cooperation on the local level. Implications for success or failure are mixed in both configurations. Policy recommendations have to be tailored to each systems' characteristics. 相似文献

The problem of adolescent drug use received a great deal of attention both in criminological theory and public policy. Predominant among theories was Akers' social learning theory which examined the role of learning through a process of imitation, modeling, and reinforcement. Public policy led to the development of programs such as Drug Abuse Resistance Education (DARE) that aimed to warn youths of the dangers of drug use. In line with research findings, both theory and policy gave a central role to peers in understanding adolescent drug use. Less attention was given to another important finding in the literature, that those who used drugs often perceived the drugs as solutions to problems. Using social learning theory, the role of perceptions of drug use as an effective problem solver was examined. Results indicated that a more explicit recognition of the use of drugs to deal with problems might inform both theory and policy. 相似文献
