Higher stakes – the hidden risks of school security fences for children’s learning environments

In a move away from the open or low-fenced grounds that have traditionally been a feature of Australian school design, the last decade has seen a growth in the installation of high-security fences around schools. These structures, far from being passive and neutral, act to redefine the possibilities for movement and connectivity in the local landscape. This paper looks beyond the impact of fences on safety and security to explore the wider implications of these structures. By bringing together perspectives on children’s experience of independent mobility, belonging and attachment to place, the paper opens up new avenues for thinking about how children’s learning is shaped by the relationship between school, community and the boundaries between them. It provides a starting point for understanding how high-security boundaries can impact on children’s learning and why at times these structures may pose more risks than those they aim to address.

Facilitating a culture of relational trust in school-based action research: recognising the role of middle leaders

Abstract

Practices such as formal focused professional dialogue groups, coaching conversations, mentoring conversations and professional learning staff meetings have been taken up in schools and pre-schools as part of long-term action research and development activities to improve the learning and teaching practices. The development of relational trust has long been described in the literature as pivotal for the ongoing ‘success’ of such research and development in sites. In this article, we attempt to re-characterise relational trust as it is accounted for by participants in action research. We present data from a cross-nation study of middle leaders from Australian primary schools and Swedish pre-schools. Middle leaders are those teachers who ‘lead across’; they have both an acknowledged position of leadership or responsibility for the practice development of colleagues and a significant teaching role. The larger study examined the practices of middle leaders; and in this article we draw on interview data from one of the case-study sites that illustrate how colleagues in schools recognise the role middle leaders have for facilitating action research and teaching development. This article specifically presents excerpts from semi-structured interviews with 25 teachers, three principals, three executive teachers and three district consultants. Interviewees described how nourishing a culture of relational trust and mutual respect are critical features in the change endeavour. For them, the practices of the middle leader who facilitated the action research were instrumental in developing trust for teacher development. Analysis of participant accounts revealed five dimensions of trust: interpersonal trust, interactional trust, intersubjective trust, intellectual trust, and pragmatic trust.

Double coupled fixed point for multi-valued mixed increasing operators in ordered Banach spaces

1 Introduction and preliminaries In 2000, Huy and Khash [1] gave some fixed point theorems for multi-valued mixed increasing operators in ordered Banach spaces by using the concept of Nishnianidze [2]. Recently, some new coupled fixed point theorems were …     

Banach空间中的局部各向一致凸和局部弱紧一致凸(英文)

1977年,Mark.A.Simith在其博土论文中(见[6])引入Banach空间中的弱紧、一致凸(URWC)凸性新概念,并给出了一个Banach空间是URED但不是URWC的例子,以及一个Banach空间是URWC但不是WUR的例子。本文继续Mark.A的工作,引入了Banach空间中的局部各向一致凸(LUREO)和局部弱紧一致凸(LURWC)两个凸性新概念。作为本文的重要结果,本文给出了一个Banach空间是LURED但既不是URED也不是LURWC的例子;一个Banach空间是LURWC但不是LURWC的例子。特别,本文还证明了熟知的严格凸(SR),实际上闵是本文所新引入的一种局部一致凸性,即:局部各向一致凸。从而使严格凸在凸性分类中找到了一个恰当的位置。通过本文的工作,使Banach空间中的凸性类型得到了完善。     

关于Orlicz-Bochner序列空间的一些注记

In this paper, we discuss some basic properties of the Orlicz-Bochner sequence space lM (X) and its subspace hM (X). We present the equivalent definition of hM (X), the sufficient and necessary conditions under which l(M) (X) is complete, and lM (X) and hM (X) are separable respectively, and also give the sufficient condition that hM (X) has a basis. All these results generalize the results for the classical Orlicz sequence spaces.
