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

The present paper operationalizes and empirically tests the most recent theoretical speculations of Hirschi and Gottfredson regarding an individual level characteristic of self-control and its relation to earlier specifications of control theory as well as the literature on personality. Linkages are drawn between their broad delineation of self-control and personal disorders of hyperactivity, impulsivity, attention deficits, and minor conduct problems. Psychologists disagree about whether such disorders represent single or multiple traits and whether both behavioral and cognitive measures can appropriately depict personality characteristics. Employing structural equation techniques, support for several propositions derived from Gottfredson and Hirschi's thesis is found: Self-control subsumes several personality disorders and is significantly comprised by early behavioral indicators of aggression and fighting, is inversely related to other elements of the social bond, is moderately stable over a short period of time, and significantly predicts criminal convictions. However, questions remain regarding the ubiquity of self-control, the magnitude and meaning of stability, and the power of this perspective to explain all forms of self-reported delinquency.  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

Conclusion Certain components of the British system of legal aid, especially the duty solicitor scheme, could beneficially be introduced in modified form into German criminal procedure. Conversely, some points of German law could benefit the British system, such as less rigid adherence to the autonomy principle. With the increasing integration of the European states, and particularly the abolition of internal border controls, it is time to think closely not only about harmonizing the economic structures of the European Community member states but also about creating human rights protections at the Community level, which is inextricably connected to access to competent legal advice in criminal proceedings.This article is a revised version of a lecture given at the Exeter University Centre for Legal and Interdisciplinary Development (EUCLID) seminar at Exeter University, Exeter, England, February 22, 1990, as part of my doctoral research project on the implementation of a duty solicitor scheme in German criminal procedure.I should especially like to thank Josephine Shaw, Lecturer in Law at Keele University and former Acting Director of EUCLID at Exeter University, for proof-reading the first draft and for supporting my research project. I am also grateful to Mervyn Bennun and Kim Economides for their helpful comments when I gave this lecture.Juristisches Staatsexamen, Universität des Saarlandes 1986; Honorary Research Fellow, University of Exeter 1989–1990; Assessor iur., Justizprüfungsamt des Saarlandes 1991; Doctor of Law, Universität des Saarlandes 1992; former Assistant to the Chair of Criminal Law, Criminal Procedure, Criminology, and Comparative Criminal Law, Universität des Saarlandes 1987–1991.  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

Abstract. Western natural law theory emphasises the derivation of principles of right action said to be universal and objective from the application of practical reasonableness to the pursuit of basic human goods that are self‐evident or based on human nature. Critics say its methodology is inherently subjective. In contrast, the Vedic approach to natural law of the Bhagavad‐Gita emphasises the full development of a universal aspect of human nature—consciousness—to promote right action. A healthy person with a developed intellect, clear mind, balanced emotions and full perception is best placed to fulfil his or her society's highest ideals of ethical and lawful conduct. The Vedic approach advocates a supportive social environment and the use of meditation techniques to promote such development. Research has found that the Transcendental Meditation (TM) program promotes improvement in mind, body and behaviour. For example, offenders in Australia, the United States and Senegal practising the technique experienced decreased substance abuse and recidivism and improved wellbeing. From a scientific perspective, TM promotes these improvements by producing a unique psychophysiological state of restful alertness that dissolves stress that blocks the unfoldment of full potential in life.  相似文献
