This paper uses one national case to illustrate how diverse ideological agendas of central state agencies contest the discursive space within which major education policy reforms are developed. In Aotearoa New Zealand in 1988, ‘self‐managed’ schools were promoted ostensibly to allow parents more say in their children’s education and local school administration. The Tomorrow’s Schools reform policy texts included an existing social democratic partnership rhetoric, positioning principals as professional leaders working collaboratively with elected parent boards of trustees. However, the new ideology of ‘parental choice’ of school within a local schooling marketplace, underpinned by a chief executive or market managerial model of principalship, was later operationalised through mechanisms of ‘steerage’ from the centre. To explain this shift, we examine selected policy text pre‐cursors to the reforms and identify how contrasting forms of ‘principal’ and ‘teacher’ identity emerged within social democratic, neo‐liberal and market managerial ideologies. We further show that while radical (Treasury) market liberal arguments for labour market deregulation and consumer choice failed to gain widespread support, the State Services Commission preferred market managerialist strategies for promoting public accountability of schools (based on aggregate student achievement outcome data and centrally determined national educational priorities) were successfully embedded during the 1990s. 相似文献

This inquiry explores who is the ‘good teacher of color’. Through Michel Foucault's notion of biopower and disciplinary power, the analysis attempts to problematize the subject-position of ‘teacher of color’ by exploring how a Latino intern and a Latina intern negotiated their subjectivity in a large diverse school district. Participants' construction of subjectivity was found to be located within the nexus of the school district, the university, and the Latino counter-discourse through which biopower and disciplinary power operated. 相似文献

Research suggests that peer mentoring can positively impact on emotional literacy competencies. This study explored the effects of peer mentoring on the emotional literacy competencies of Year 7 peer mentees using a quasi-experimental pre-test and post-test control group design. Results supported the hypothesis that peer mentoring has a positive impact on the emotional literacy competencies of mentees with low to average levels of emotional literacy at pre-intervention. Results also showed a significant negative correlation between attendance at sessions and perceived Conduct Problems. Unexpectedly, results indicated adverse effects of reading mentoring on the emotional literacy competencies of control participants. 相似文献

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines. 相似文献

In classical model reference adaptive control (MRAC), the adaptive rates must be tuned to meet multiple competing objectives. Large adaptive rates guarantee rapid convergence of the trajectory tracking error to zero. However, large adaptive rates may also induce saturation of the actuators and excessive overshoots of the closed-loop system’s trajectory tracking error. Conversely, low adaptive rates may produce unsatisfactory trajectory tracking performances. To overcome these limitations, in the classical MRAC framework, the adaptive rates must be tuned through an iterative process. Alternative approaches require to modify the plant’s reference model or the reference command input. This paper presents the first MRAC laws for nonlinear dynamical systems affected by matched and parametric uncertainties that constrain both the closed-loop system’s trajectory tracking error and the control input at all times within user-defined bounds, and enforce a user-defined rate of convergence on the trajectory tracking error. By applying the proposed MRAC laws, the adaptive rates can be set arbitrarily large and both the plant’s reference model and the reference command input can be chosen arbitrarily. The user-defined rate of convergence of the closed-loop plant’s trajectory is enforced by introducing a user-defined auxiliary reference model, which converges to the trajectory tracking error obtained by applying the classical MRAC laws before its transient dynamics has decayed, and steering the trajectory tracking error to the auxiliary reference model at a rate of convergence that is higher than the rate of convergence of the plant’s reference model. The ability of the proposed MRAC laws to prescribe the performance of the closed-loop system’s trajectory tracking error and control input is guaranteed by barrier Lyapunov functions. Numerical simulations illustrate both the applicability of our theoretical results and their effectiveness compared to other techniques such as prescribed performance control, which allows to constrain both the rate of convergence and the maximum overshoot on the trajectory tracking error of uncertain systems. 相似文献

In this paper we present a new fabrication method that combines for the first time popular SU-8 technology and PerMX dry-photoresist lamination for the manufacturing of high aspect ratio three-dimensional multi-level microfluidic networks. The potential of this approach, which further benefits from wafer-level manufacturing and accurate alignment of fluidic levels, is demonstrated by a highly integrated three-level microfluidic chip. The hereby achieved network complexity, including 24 fluidic vias and 16 crossing points of three individual microchannels on less than 13 mm(2) chip area, is unique for SU-8 based fluidic networks. We further report on excellent process compatibility between SU-8 and PerMX dry-photoresist which results in high interlayer adhesion strength. The tight pressure sealing of a fluidic channel (0.5 MPa for 1 h) is demonstrated for 150 μm narrow SU-8/PerMX bonding interfaces. 相似文献

During Chinese Vice Premier Li Keqiang’s official visit to Australia in October 2009, Chinese and Australian leaderships reached a consensus of hosting cultural years in each other’s country. From June 2010 to June 2011, "Experience Australia"—the Year of Australian Culture was successfully held in China. From June 2011 to June 2012, "Experience China"—the Year of Chinese Culture (YCCiA) is celebrated in Australia, featuring nearly 100 cultural events ranging from performing arts projects to visual art exhibitions to film festivals. 相似文献

Public cultural ser vice has gained increasing attention worldwide in recent years. It has become ever y government’s top priority to build a well-developed public cultural service system, provide diverse cultural products and promote cultural consumption by the public. In one-day disccusions of the Cultural Session, participants shared each other’s experience in public cultural service, in particular, concepts and practices of Xi’an City. Participants reached a consensus of increasing exchanges and cooperation in the sector of public culture in the future. 相似文献
