Contemporary education reforms that draw ideas from the political and economic fields are said to be altering the nature of vocational education. While there are substantial policy studies on the effects of marketisation reforms, fewer analyse the perspectives of vocational educators on such reforms. How vocational educators negotiate the potential clash of values when marketisation reforms are enacted within the sector remains relatively unexplored. This paper aims to incorporate these perspectives in order to explore and help explain the responses of vocational educators to such changes. To do so the paper draws on concepts from Legitimation Code Theory, a sociological framework for analysing practices and beliefs. Specifically, it enacts ‘autonomy codes’, which reveal how external forces impact upon the internal practices of a social field. These concepts are used to analyse the beliefs and perceptions of a group of vocational educators in Australia who are undergoing marketisation reforms. The analysis suggests that many educators are experiencing a growing ‘code clash’ between the goals they attribute to reforms and their own beliefs about public education and the expectations of their students, one which problematises their capacity to reconcile these sets of values and colours their views of changes in the sector. 相似文献

Reversible variable length codes (RVLCs) have received much attention due to their excellent error resilient capabilities. In this paper, a novel construction algorithm for symmetrical RVLC is proposed which is independent of the Huffman code. The proposed algorithm's codeword assignment is only based on symbol occurrence probability. It has many advantages over symmetrical construction algorithms available for easy realization and better code performance. In addition, the proposed algorithm simplifies the codeword selection mechanism dramatically. 相似文献

Breaches in academic integrity are a pervasive and enduring international concern to the overall quality of higher education. Despite students being the group most affected by academic integrity policies, organisational culture is such that students tend to be passive recipients of change initiatives, rather than the drivers. To deliver a paradigm change, a theory of change framework was designed, implemented and applied to explore the viability of a student-led academic integrity society. To achieve this, a national research project involving three stages of data collection (surveys, interviews and focus groups) was conducted to obtain the perspectives of students and student representatives. The key outcome of the project has been the recent launch of an academic integrity student society, a novel initiative outside the United States of America. The theory of change framework presented here seeks to offer guidance to other institutions contemplating the viability of student-led change to academic integrity and the establishment of academic integrity student societies, in particular. 相似文献

Understanding of the 1980 riot at the Penitentiary of New Mexico can be improved by emphasizing how language congealed into two distinct codes—one belonging to inmates, the other to prison administrators—that provided their respective users with diametrically opposed views of the world and ways of acting upon it. A code‐based analysis of the riot attempts to overcome some of the shortcomings of both agency‐based and structuralist accounts by stressing the dynamics of agency and structure within code opposition. By so doing, the analysis offers critical diagnostic tools for communication analysts and conflict mediators who may be called upon to intervene in social situations where agents appear to be locked intractably in oppositional conflict. 相似文献
