There is widespread concern that higher education is being compromised by being turned into a ‘commodity’ to be ‘consumed’. This article represents an initial attempt to explore the trends in both the UK and US, and considers how the law has responded to them. It argues, however, that there is an important distinction to be drawn between ‘commodification’ and ‘consumerism’. Education has always been a commodity to be bought and sold; the true danger lies in the move to a ‘rights-based’ culture where students (and politicians) see education merely as something to be ‘consumed’ rather than as an activity in which to participate. Whilst the law seems thus far to have been something of a bulwark against this movement, it remains an open question as to whether this will continue to be the case if HEIs do not themselves act more proactively in challenging this damaging view of higher education.  相似文献

Weit weg und mittlerweile doch sehr nah liegt die Antarktis, wenn es um Klima- und Umweltschutz geht. Forschung und Tourismus strapazieren den au?ergew?hnlichen Naturraum. Der Beitrag zeigt auf, mit welchen Steuerungsans?tzen Deutschland seinen Verpflichtungen zum Antarktisschutz gerecht werden will. Ausgehend von einigen Informationen über den 6. Kontinent (A.) werden die unterschiedlichen Interessenkonflikte rund um Nutzung und Schutz der Antarktis illustriert (B.). Im Anschluss daran wird der zugeh?rige internationale und nationale Rechtsrahmen kurz vorgestellt (C.), ehe verschiedene Facetten des deutschen Ausführungsgesetzes n?her beleuchtet werden (D.). Flankierend wird neben dem Ordnungsrecht eine gute fachliche Praxis in Form eines Leitfadens als Element nichtrechtlicher Steuerung genutzt (E.). Der Beitrag schlie?t mit Fazit und Ausblick (F.).  相似文献

While the concepts of race and ethnicity have been abused historically, they are potentially invaluable in epidemiology and public health. Epidemiology relies upon variables that help differentiate populations by health status, thereby refining public health and health care policy, and offering insights for medical science. Race and ethnicity are powerful tools for doing this. The prerequisite for their responsible use is a society committed to reducing inequalities and inequities in health status. When this condition is met, it is irresponsible not to utilize these concepts.  相似文献

Several studies had concluded that the police subculture holds values and attitudes that are distinct from the rest of the population. Among these values is a focus on law and order. While researchers agree that police tend to hold different values, they disagree on the source of the attitudes. Some had argued that the attitudes reflected differences regarding who was recruited for law enforcement careers while others said that the differences reflected changes that occurred to individuals after becoming officers. This study examined whether police officers and students enrolled in criminal justice/sociology classes held similar or different attitudes towards the Miranda warnings. The findings suggested that in some ways, the two groups perceived the warnings in dramatically different ways, while in other ways their differences were simply a matter of degree. Implications are provided.  相似文献

This article examines the effects of negotiation practices, such as coercion and contract formality, on how suppliers and customers perceived the resulting business relationship. We conducted a purchasing negotiation simulation with students in a classroom setting in which participants competed for resources in a mock supply-chain context. The participants were surveyed at key stages of the ongoing negotiation in order to measure their behaviors as a customer–supplier relationship developed. The data were used to test several hypotheses developed from the marketing and purchasing literature. The hypotheses were analyzed using structural equation modeling.
Results demonstrated that the use of coercive techniques by negotiators during negotiation had a negative effect on satisfaction. In addition, the findings showed that, as expected, negotiators entering a negotiation with a cooperative orientation would tend to avoid the use of coercive practices during negotiation. The cooperative orientation also exhibited an unexpected positive effect on the formalization of the design of the contract between the parties. This study contributes to the current knowledge base focusing on the creation of agreements between companies and will, we hope, encourage the integration of suppliers and customers in an operating context within a supply-chain setting.  相似文献
