The New Zealand Government's Performance Improvement Framework (PIF) is aimed at public sector organisational improvement. The PIF exemplifies how the characteristics of new public management (NPM) challenge the evolution of performance systems attempting to go beyond performance management. The paper provides an empirical example of the operation of the PIF, using a theoretical frame derived from the literature. The analysis suggests that the PIF design does not yet mitigate the effects of gaming, synecdoche, and reputation-protecting behaviour. The common graded ratings continue to hold the attention of those to whom the PIF is important, acting as a proxy for the whole performance of the organisation. This is a case study of how, despite promising adaptations, performance improvement efforts remain hampered by NPM limitations.  相似文献

Student engagement is an important contributor to school success, yet high school students routinely describe themselves as disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement. This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse (67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs and its relationship to educational practice is discussed.  相似文献

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs—adolescence and young adulthood—in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.  相似文献

Previous studies have used probit or logit models to analyze two states of monetary policy (tighter or looser). In this paper we employ multinominal logit to permit Federal Reserve monetary policy to assume one of three alternative states (tighter, looser, or no change) as a function of three independent economic variables (unemployment, real growth, and inflation) and the amount of experience of the Board of Governors. The results indicate that the Federal Reserve reacted differently under Burns, Miller and Volcker and between Volcker's two operating procedures in the formulation of monetary policy.  相似文献

A laboratory study interested in the analysis of human hair for drugs-of-abuse was conducted to determine if drugs could be detected and quantified from hair. Supercritical fluid extraction (SFE) techniques followed by GC-MS analysis were applied to extract amphetamines from hair. The group of amphetamines included methylenedioxyamphetamine (MDA), methylenedioxymetamphetamine (MDMA), methylenedioxyethylamphetamine (MDEA) and internal standard mephentermine (MP). To validate information on amphetamine use in hair, powdered hair samples free from drugs were collected and soaked in a known amphetamine standard solution. Authentic fortified case hair samples taken from known drug users known to have consumed amphetamines were also analyzed for amphetamine. Results from this study show that amphetamine use can be detected in spiked and authentic fortified human hair using SFE techniques for qualitative and quantitative reproducible results.  相似文献
