Compulsory competitive tendering (CCT) has been an important instrument of Conservative government economic policy since 1979. Its effectiveness in generating cost-effective services depends on competition to supply the service in question.
The NHS domestic market is large and, prior to the introduction of CCT, promised to be profitable for contractors. Many contract cleaners with office cleaning experience entered. In the event the costs of entry were heavy, and the profit margins of established firms were reduced. When contracts have been awarded to firms, they tended to be to those with a track record. Many firms therefore withdrew; and the few that remained have profit margins in the NHS little different from those found elsewhere. Of more than by firms with a serious interest in entry, probably no more than a handful can have come out of the experience in net profit in the first seven years.
The experience of CCT in the market for NHS domestic services has shown that a degree of competition in the market can be achieved, arguably because of the presence of direct service organizations. Competition for this market, on the other hand, can be limited by the high costs of entry.  相似文献

Recently criminologists have begun to explore the importance of disaggregating frequency measures of self-reported delinquency into the separate decisions of initiation and continuation. Given that labeling makes predictions concerning continuation, the purpose of this paper is twofold. The first is to test the ability of an informal labeling model to predict the decision to continue delinquent behavior once it is initiated. The second purpose is to address the broader question of whether disaggregation matters. The findings support the idea that the informal labeling model is predictive of the decision to continue delinquent behavior. The findings also suggest that, at least for a measure of general delinquency, there are some differences to be found by choosing the appropriate sample and form of the dependent variable.  相似文献

Social scientists have theorized about the cycle of domestic violence in family abuse. Little research has addressed dating violence as a consequence to the experience of domestic violence by children. This article deals with the self-reported experience of dating violence by high school students from abusive and nonabusive households. A survey was conducted of 1,353 students in a rural area of North Dakota. Results indicated that students from abusive households showed significantly higher incidence of dating violence than those from homes where no abuse was evident. However, less than one in five of the students from abusive home reported dating violence, providing little support for the cycle of violence hypothesis. Students from abusive homes viewed violence as negatively as students from nonabusive homes. Thus, while there are significant differences between the two groups, there are also important similarities. Although there is apparently a greater risk of dating violence among students who have experienced violence at home, these data do not support the idea of an inescapable pattern of violence among adolescents who have experienced violence themselves.  相似文献

This article investigates the effect of Computer Assisted Monitoring of Offenders (CAMO) on probation outcome. In a comparison sample, the effect of CAMO treatment is compared to the effect of “regular” probation. In addition to testing the effects of CAMO as an intermediate treatment, methodological issues, such as level of probation restrictiveness and the effects of prior criminal involvement on probation outcome, are tested. Although the results are mixed, they indicate that level of probation restrictiveness and prior criminal involvement have a greater effect on probation outcome than does CAMO. These findings have ramifications for researchers comparing CAMO probationers to “regular” probationers and for those comparing different CAMO programs. An earlier version of this paper was presented at the Western Social Science Association’s 1992 annual conference.  相似文献

In the forensic science laboratory, the recovery of spermatozoa from vaginal swabs, or vaginal cells from penile swabs, can help determine if sexual intercourse may have taken place. There are several methods used to recover spermatozoa and cells from the swabs before visualisation on a microscope slide and most of these methods use water. Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis. This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling.  相似文献

Der Begriff der Landeskultur umfasst alle Maßnahmen zur Verbesserung der land- und forstwirtschaftlichen Nutzung des Bodens einschließlich der Erhaltung der Kulturlandschaft. Landeskultur ist somit alles Planen und Handeln mit dem Ziel, die Umwelt als gegebenes Naturraumpotential, insbesondere Wasser, Boden, Luft und die dazugehörigen Natur-, Kultur- und Sachgüter optimal zu erhalten, gestalten und rationell zu nutzen sowie dieses Potential mit bestmöglicher Qualität als natürliche und kulturelle Lebensgrundlage für die Allgemeinheit nachhaltig zu sichern. Landeskultur dient somit auch der Belebung und Werterhöhung der gebauten und gepflanzten Umwelt. Dies schließt auch und gerade die kulturelle Seite einschließlich Kulturlandschaften mit ein. Dabei ist es bis zur Überprüfung durch das BVerfG noch hinnehmbar, dass der Begriff „Landeskultur“ in Art. 89 Abs. 3 GG wegen der Mischkompetenz von Bund und Land vom BVerwG enger ausgelegt wird als in anderen Rechtsvorschriften.  相似文献

Das im November 2005 in Kraft getretene und kürzlich punktuell ge?nderte Projekt-Mechanismen-Gesetz bildet die gesetzliche Grundlage für die Beteiligung der Bundesrepublik Deutschland an in- und ausl?ndischen Klimaschutzprojekten im Rahmen der projektbezogenen flexiblen Mechanismen des Kyoto-Protokolls. Mit ihm sollen Unternehmen aus dem In- und Ausland zur „Anmeldung“ ihrer Klimaschutzprojekte in Deutschland gewonnen werden. Sowohl die grunds?tzliche Verabschiedung des Gesetzes als auch die genannte Motivation sind zu begrü?en. Dennoch ist eine Reihe von ?nderungen weiterhin erforderlich.  相似文献

Toxicologic findings in the USS Iowa disaster.   总被引:5,自引:0,他引:5  
The toxicologic results from the 47 victims of the explosion on the USS Iowa are presented. Good correlation between carboxyhemoglobin saturations and cause of death was found. There were no correlations between blood cyanide concentrations and causes of death. Volatile analysis suggested postmortem ethanol production rather than antemortem ethanol ingestion. No drugs except nicotine were detected in any of the victims.  相似文献
