From myths to models: the (re)production of world culture in comparative education

This article traces the emergence of the world culture theory in comparative education using critical discourse analysis. By chronicling the emergence and expansion of world culture theory over the past four decades, we highlight the (unintended) limitations and exclusive regimes of thought that have resulted. We argue that the theory's telos of a ‘world culture’ neglects the notions of power and agency, and continues to use discourses of modernism and ‘scientific’ methodology to justify conformity as the reigning global ‘norm’. The world culture theory ultimately results in an unwitting legitimisation of neoliberal policies and its varied educational projects. Drawing on the micro-, meso- and macro-levels of discourse analysis, we examine how the semantics and content of the world culture theory have evolved as it embraced an increasingly large and diverse community of scholars aligned with it. By highlighting some significant semantic shifts during the last four decades, we explore how the world culture theorists forged a relatively new (privileged) space in comparative education – a space that has increasingly turned deterministic and normative. Through a careful deconstruction of some of the basic assumptions of world culture theory, we call for reopening of an intellectual space for new ways of thinking about educational phenomena in the context of globalisation.

李大钊与毛泽东中西文化观的趋同性

在对传统文化和西方文化进行评判、比较,以及对中西文化冲突条件下中国文化发展路径所作的探索过程中,李大钊与毛泽东的中西文化观呈现出诸多趋同性：对传统文化都强调批判继承、古为今用;对西方文化都强调选择借鉴、洋为中用;在中西文化之比较中都主张融合中西文化,创造中国新文化。研究和探讨李大钊与毛泽东中西文化观所蕴含的丰富内容及其所展现的先进性,对于我们正确认识中国共产党人文化观的理论渊源及其思想体系历史发展的逻辑性和继承性,指导中国先进文化建设具有重要意义。     

Error analysis for remote nonlinear iterative learning control system with wireless channel noise

In this paper, the iterative learning control problem is considered for a class of remote control system over wireless network communication channel. The control performance of remote iterative learning control (R-ILC) system is analyzed and an error boundary of the stable output of the R-ILC system is obtained for the boundary stochastic noise channel. Finally, we obtain some rules to reduce the fluctuation caused by wireless channel noise through the analysis results for fluctuation boundary. The simulation results prove the proposed rule is correct.

On the margins or at the center? Distance education in higher education

Abstract

This reflection focuses on the position of distance education in today’s global higher education. Firstly, it identifies three types of convergence of distance and campus-based education – dual mode, add-on/blended, and full convergence – arguing that the last type has yet to be fully realized due to the complexities involved. It then critiques the interplay between the two, concluding that despite being influenced by campus-based instructional delivery in its early days, distance education is now influencing campus-based education. Implications of convergence are also discussed. Arguably, distance education universities should be proud of the increasing presence of distance education in campus-based universities and have confidence in maintaining their advantages. As for campus-based universities, a systems approach is needed if they intend to take advantage of this ‘unorthodox’ mode of education. Finally, it is suggested that both campus-based education and distance education are at the center of higher education because they are now equally conventional.
