Professional identity and pedagogical space : negotiating difference in teacher workplaces

This paper explores ‘spatial struggle’ in the formation of professional identities of overseas born teachers. The basis of this struggle arises from a limited number of subject positions available for them in pedagogical spaces of the Australian system of education. We argue that relations of power/professional knowledge in teacher workplaces as well as the binary strategy of ‘us’ and ‘them’ generate marginal locations for overseas born teachers within schools. This construction of marginality is informed not only by discourses of what counts as being a professional but also by the conception of workplace – spaces of the school, staffroom and classroom – as monocultural, pre-given and bounded entities (McGregor, 2003). By rethinking workplaces as relational, as spaces that are connected to other sociocultural places as well as spaces of semiotic flows, we can also rethink the professional becoming of overseas born teachers. This involves a critical understanding of their positionality, which can be conceptualised as a struggle for voice within “a cacophony of past and present voices, lived experiences and available practices” (Britzman, 1991, p.8). It is because of this polyphony of voices and multiplicity of experiences that the process of professional identity formation for ‘alien’ teachers should be seen as becoming in continual negotiation of power/knowledge relations within workplaces. Recognising this dynamic is important for re-constructing our pedagogical spaces and, in turn, for a more equitable workplace practices.

Professional identity and pedagogical space : negotiating difference in teacher workplaces

This paper explores "spatial struggle" in the formation of professional identities of overseas-born teachers. The basis of this struggle arises from a limited number of subject positions available for them in pedagogical spaces of the Australian system of education. We argue that relations of power/professional knowledge in teacher workplaces as well as the binary strategy of "us" and "them" generate marginal locations for overseas-born teachers within schools. This construction of marginality is informed not only by discourses of what counts as being a professional but also by the conception of workplace as a monocultural, pre-given and bounded entity. By rethinking workplaces as relational, as locations that are connected to other socioculturally produced places through spaces of semiotic flows, we can also rethink the professional becoming of overseas-born teachers. This involves a critical understanding of their situationality, which can be conceptualised as a struggle for professional recognition, voice and place within the real and imagined communities of teachers.

Perceptions of change in office space design: redesigning Barwon Water’s office environment

In early 2015 Barwon Water received State government funding to rationalise and renovate its various Geelong-based administrative offices into one complex. Integral to the renovations is a new green-star retrofit of the existing Ryrie Street complex by GHD Woodhead. The project will consolidate all of Barwon Water’s offices onto one site, increase floor space, provide a new ‘green’ atrium, and adopt an open plan layout. Having set a new strategic direction, Barwon Water is now undergoing a wholesale cultural and operational change in order to realise these strategic objectives. Aspirations for workplace design have been identified as: environmentally sustainable; foster innovation and creativity; establish connections; improve communication and collaboration; provide efficient space for effective work; flexibility over time; welcoming and connected to the community; healthy; and, up to date technology. This paper investigates Barwon Water staff perceptions and apprehensions of this prospective consolidation, particularly the proposed open plan office environment. While most research in this topic is informed by an immediate pre-design workshop of staff needs, this research provides a longitudinal perspective of human perceptions about work place environment change and a review of how changes in office environment synergistically align to architectural responses and changes in corporate strategies.

Characteristics evaluation of a μ-Synthesis H∞ controller for a grid-connected three-phase photovoltaic system

This paper presents a μ-Synthesis H∞ Controller for regulating the switching signal of the inverter connected with a three-phase photovoltaic (PV) system. To facilitate the control design, the system is represented in terms of state space realization with uncertainties. The control design involves selecting proper weighting functions and performing synthesis. The controller order is reduced by Henkel-norm method. Simulations are carried out to evaluate the characteristics of the controller under parametric uncertainties. It is found out that the proposed controller is inherently stable, possesses significantly small tracking error, and preserves nominal performance, robust stability and robust performance for the grid-connected three-phase PV system.

Space-crossing : community-based data forwarding in mobile social networks under the hybrid communication architecture

In this paper, we study two tightly coupled issues, space-crossing community detection and its influence on data forwarding in mobile social networks (MSNs). We propose a communication framework containing the hybrid underlying network with access point (AP) support for data forwarding and the base stations for managing most of control traffic. The concept of physical proximity community can be extended to be one across the geographical space, because APs can facilitate the communication among long-distance nodes. Space-crossing communities are obtained by merging some pairs of physical proximity communities. Based on the space-crossing community, we define two cases of node local activity and use them as the input of inner product similarity measurement. We design a novel data forwarding algorithm Social Attraction and Infrastructure Support (SAIS), which applies similarity attraction to route to neighbor more similar to destination, and infrastructure support phase to route the message to other APs within common connected components. We evaluate our SAIS algorithm on real-life datasets from MIT Reality Mining and University of Illinois Movement (UIM). Results show that space-crossing community plays a positive role in data forwarding in MSNs. Based on this new type of community, SAIS achieves a better performance than existing popular social community-based data forwarding algorithms in practice, including Simbet, Bubble Rap and Nguyen's Routing algorithms.
