A rapid and efficient procedure is described for the extraction and analysis of oxazepam, the major urinary metabolite of diazepam in greyhounds. Urine was extracted by passing through a bonded silica column (Bond Elut) following enzyme hydrolysis. The adsorbed drug was eluted and then detected and measured by high performance liquid chromatography (HPLC). Recoveries were in excess of 85% at 50 ng/ml concentrations. Detection was possible up to 30 h after a single oral dose of diazepam (5 mg).  相似文献

This article examines whether the payoff from engaging in innovation‐generating activities is contingent on an organization's level of customer and learning orientation. The authors suggest that innovative activity is associated with higher public service quality when the level of customer and learning orientation within the focal organization is high. They test this hypothesis by drawing on a novel panel data set covering all public nonspecialist hospital organizations in England. Using dynamic panel data estimation techniques, the authors find strong support for a direct relationship between innovative activity and public service quality and for a moderating role of both customer and learning orientation. These findings call for a contingency perspective on public sector innovation and highlight some of the boundary conditions that need to be in place if public service organizations are to benefit fully from their innovative activities.  相似文献

Using our own experiences in attempting to ‘do’ public criminology in the wake of a violent sexual assault on our campus, we offer a critique of the emerging public criminology framework. Focusing specifically on tensions between fact and emotion and representations of expertise in the news media, we argue for a greater respect for emotional responses to crime in moving the public criminology agenda forward. We suggest that if public criminology sets as its goal educating the public about crime with an eye towards injecting a counter/critical discourse into ‘get tough’ crime control policies, then public criminologists need to recognize and take seriously the public’s emotions rather than negate them. Drawing on the work of Ahmed (The cultural politics of emotion. Routledge, London, 2004), we suggest that the role of the expert is not to simply inform citizens of the ‘facts’ about crime, but to establish—through emotions—the relationship between themselves and the imagined criminal Other (Young in Imagining crime: Textual outlaws and criminal conversations. Sage Publications, London, 1996). Thus, alongside trying to convince the public to be more ‘rational’ when it comes to crime, critical criminologists must start to accept people’s fear and anger as legitimate reactions and try to redirect these emotions toward more productive ends.  相似文献
