Comparing experiments of the stressed skin diaphragm spanning several and few purlins

Concerning the specialty of the testing of stressed skin diaphragm assembly, the current loading method of cantilever beam test is improved by the diagonally loading method. In order to investigate the differences of the shear behavior between the stressed skins spanning several purlins and few purlins , which have the same forms and spaces of the connections and purlins, comparing experiments are carried out. Using the curve fitting method, the test results are quantified. The shear rigidity of two specimens is gained. It shows that the shear rigidity of the diaphragm spanning several purlins is quite higher than that spanning few purlins, but the carrying capacity of the former is a little lower than that of the latter.

The use of public transport in coastal Australia : modes of travel to work and greenhouse emissions

Commuting to work is one of the most important and regular routines of transportation in towns and cities. From a geographic perspective, the length of people’s commute is influenced, to some degree, by the spatial separation of their home and workplace and the transport infrastructure. The rise of car ownership in Australia from the 1950s to the present was accompanied by a considerable decrease of public transport use. Currently there is an average of 1.4 persons per car in Australia, and private cars are involved in approximately 90% of the trips, and public transportation in only 10%. Increased personal mobility has fuelled the trend of decentralised housing development, mostly without a clear planning for local employment, or alternative means of transportation. Transport sector accounts for 14% of Australia’s net greenhouse gas emissions. Without further policy action, Australia’s emissions are projected to continue to increase. The Australian Federal Government and the new Department of Climate Change have recently published a set of maps showing that rising seas would submerge large parts of Victoria coastal region. Such event would lead to major disruption in planned urban growth areas in the next 50 years with broad scale inundation of dwellings, facilities and road networks. The Greater Geelong Region has well established infrastructure as a major urban centre and tourist destination and hence attracted the attention of federal and state governments in their quest for further development and population growth. As a result of its natural beauty and ecological sensitivity, scenarios for growth in the region are currently under scrutiny from local government as well as development agencies, scientists, and planners. This paper is part of a broad research in the relationship between transportation system, urban form, trip demand, and emissions, as a paramount in addressing the challenges presented by urban growth. Progressing from previous work focused on private cars, this present paper investigates the use of public transport as a mode for commuting in the Greater Geelong Region. Using a GIS based interaction model, it characterises the current use of the existing public transportation system, and also builds a scenario of increased use of the existing public transportation system, estimating potencial reductions in CO2 emissions. This study provides an improved understanding of the extent to which choices of transport mode and travel activity patterns, affect emissions in the context of regional networks. The results indicate that emissions from commuting by public transportation are significantly lower than those from commuting by private car, and emphasise that there are opportunities for large abatment in the greenhouse emissions from the transportation sector related to efforts in increasing the use of existing public transportation system.

The experience of Singapore in raising awareness of natural and cultural resources

The city-state of Singapore has a major role in the urban development. Majority of the innovative projects are initiated by the government agencies. For this paper, I would like to highlight the two distinct themes of innovation that, I believe preoccupied the authority for its urban issues, they are innovation which concern nature and culture. Land in Singapore is scarce. Natural resources are strictly protected. At the same time they are challenged to return the maximum benefit to their own population. The water catchment area and the prime forest on the whole island is the most valuable natural resources to be preserved. The paper will demonstrate how Singapore challenges with its own resources (water and greenery) in which the holistic planning around these themes become more than just spaces of protection but integrated with the public space system and turned into more valuable spaces for the well being of its population. The second theme is the issue related to culture. Singapore's economy is the most advance compare to other Southeast Asian countries, however when it comes to culture and identity, the city state struggles with the over constructed image of branding Singapore's culture. The paper will discuss several examples around the theme of arts and culture, how the city state bench-mark itself with the world class cities. It is one of the most challenging topic in urban planning and policy making. It is worth discussing on its success and failure. We can learn form Singapore that innovation at the level of policy maker can be achieved in some urban aspects such as the management of natural resources and urban design projects related to it. However when it comes to the issue related to art and culture, the top down policy alone cannot assure the achievement of city's identity as it aspired. Tracing the historical development of the environmental and cultural policies of Singapore the paper intends to study and analyze various case studies reflecting these attempts of natural and cultural instillation. In the process of comparison of these two drastically contrasting actors and approaches, the paper will argue that it has mostly been driven by economic aims, and careful thought. The results have been limited and restrictive. Further arguing that 'creativity' is the essential factor of arts and culture, it evaluates the authenticity and the ultimate implications on cultural spirit.

Investigating the effectiveness of teacher education for early career teachers in diverse settings: the longitudinal research we have to have

There have been more than 100 reports focusing on the effectiveness of teacher education in Australia over the last 35 years with many positioning teacher education as flawed and in need of reform. These frequent criticisms have drawn attention to the difficulty teacher educators can experience when trying to interrupt or contest this representation: a situation not unique to Australia. In the United States, for example, Pam Grossman has suggested that those in teacher education “seem ill prepared to respond to critics who question the value of professional education for teachers with evidence of our effectiveness” (Grossman in J Teach Educ 59(1):10–23, 2008). A key question facing teacher educators, therefore, concerns the kinds of research that will most effectively allow us to lead debates about teacher preparation. This paper outlines an approach to the conceptualization and conduct of research into the effectiveness of teacher education that seeks to move debates in new directions. Drawing upon the theoretical resources of Soja (Thirdspace: journeys to Los Angeles and other real-and-imagined places, 1996) and Lefebre (The production of space, 1991) we outline the ways in which a spatial approach to conceptualizing teacher education influenced the design and conduct of a large scale, longitudinal project that investigated the question of the effectiveness of teacher education in Australia. In exploring the design features of this ARC linkage grant the paper demonstrates how research changes when teacher education is conceptualised from a spatial point of view and illustrates the ways in which consideration of the conceived, perceived and lived spaces of teacher education can move research about effectiveness into new directions.

Biodegradable polyethylene glycol-based ionic liquids for effective inhibition of shale hydration

A series of ionic liquids based on polyethylene glycol (PEG) with different molecular weights were prepared for inhibiting shale hydration and swelling. The antiswelling ratio was measured to investigate the effect of different PEG-based ionic liquids on bentonite volume expansion, and it has shown that the ionic liquid based PEG200, i.e. PEG with molecular weight of 200, exhibited superior inhibition. The structures of the PEG200-based ionic liquids were characterized by ¹H NMR studies. The XRD results indicated that the PEG200-based ionic liquids intercalated into sodium montmorillonite (Na-MMT) reducing the water uptake by the clay. The formation of complexes of Na-MMT and PEG200-based ionic liquids was also verified by FTIR spectroscopy. Thermal degradation analysis suggested that the PEG200-based ionic liquids accessed the interlamellar spaces of Na-MMT and reduced the water content of the complexes obtained. Moreover, no breaks and collapse were observed on the shale samples after immersion in PEG200-based ionic liquid solutions. All the PEG200-based ionic liquids showed biodegradability and potential application in effective inhibition for clay hydration.

Legal systemology and the geopolitics of Roman law: a response to Stuart Elden’s critique of Carl Schmitt’s spatial ontology

This paper explores the production, destruction, and reproduction of the geopolitical spaces of Roman law in order to offer an analysis of Schmitt’s (selective) notion of Jus Publicum Europaeum and its relevance to the current “depoliticization” and “dejuridification” of the world. By adopting a historical and geopolitical approach that reaches the boundaries of legal systemology and political theology, the present contribution investigates the manipulative and instrumentalist use of the material object of Rome’s (universalist) competence, namely the “territory” as dominium of its political intervention, which was ultimately (and idealistically) aimed at avoiding the natural destiny of any living being: birth, maturity, and death. Attention is therefore paid to the Roman strategy of (ontological?) contamination of its mythical identity through the legal and sociopolitical administration and regulation of its geographical spaces in terms of (non-)cultural signification. Through the analysis of such concepts as “nomos,” “Großraum,” “Ortung,” and “Ordnung,” it is claimed that Schmitt voluntarily chose to identify the Jus Publicum Europaeum with the geopolitical order produced during the Age of Discovery and not with the “comprehensive” Roman spatial order. The reason for this choice may be identified in the distortive use of Rome’s social relations and political allegiances that lay at the core of its genealogical expansionism (and subsequent inevitable dissolution) since the conquest of Veius in 396 BC and the historical compromise between patrician nobility and plebeians in 367 BC.

Muslim citizenship in everyday Australian civic spaces

Questions about Muslims, multiculturalism and citizenship continue to shape the political discourse of many nations, including Australia, a nation often foregrounded as a beacon of multiculturalism in practice. The key assumption underlying these questions is that Islam constrains the full possibilities of citizenship in multicultural secular societies and that Muslims must be actively steered towards participation in civic life. By contrast, this article, based on research with 80 young Australian Muslims from migrant backgrounds reveals how Australian Muslims are enacting everyday citizenship through active, self-driven participation in multicultural civic spaces. This is a process overlooked by contemporary government approaches to the management of Muslim communities and alike. This article argues that is it access to these spaces of everyday interaction rather than an emphasis upon securitisation and civic literacy that fosters the development of citizenship and civic engagement central to the success of Australian multiculturalism. The article provides important considerations for those concerned with the future viability of multicultural policies.

Navigating the demands of the English schooling context: problematics and possibilities for social equity

The English schooling context has seen radical and rapid reform in recent times with the processes of devolution or deconcentration of centralised school governance, on the one hand, and the instating of ever-increasing and rigid external accountabilities, on the other. These reforms driven as they are by neoliberal and neoconservative ideologies have created a new kind of ‘system’ of schooling in England, one that is ‘heterarchical’ in governance, increasingly complex in its overlap, multiplicity and asymmetric power dynamics, but one that remains strongly tied to and regulated by the reductive and narrow measure of ‘success’ imposed by the state. Against this complex and changing backdrop, what constitutes quality and equitable schooling has been transformed. This special issue explores these concerns and, in particular, focuses on how the current demands of the English schooling context construct student achievement and identity, teachers’ work, conceptualisations of knowledge and pedagogy, and school organisation and collaboration. The issue has a strong equity focus. Many of the papers to this end focus on how teachers and schools are navigating through the demands of current policy reform to mobilise spaces of possibility for equity and good schooling. In this paper, we provide a context and framework to set the scene for the subsequent papers in the issue.

Identity politics, justice and the schooling of Muslim girls: navigating the tensions between multiculturalism, group rights and feminism

This article focuses on the concerns expressed by three female Muslim educators who are support staff at an English comprehensive school. Consistent with the debates associated with multiculturalism, group rights and feminism, the article illuminates spaces of gender constraint and possibility within the discourses shaping these women’s lives and the lives of the Muslim girls they educate. With reference to an initiative at the school designed to support these girls’ greater self-determination – an Islamic discussion group – the article highlights the significance of a justice politics that begins with overcoming relations of status subordination rather than on differentiated group identity.

Disrupting (gendered) Islamophobia: the practice of feminist ijtihad to support the agency of young Muslim women

Muslim feminist scholars highlight, and seek to transform, racist, sexist and Islamophobic discourses through feminist interpretations of their religion. This paper reports on data gathered from an interview-based study involving four young Muslim women from the same Brisbane (Queensland) community. The focus is on how these young women are understanding, and finding spaces of agency, within these discourses with reference to their faith. The Islamic principle of ijtihad (jurisprudential interpretation of religious text) and the practice of feminist ijtihad are theorized as powerful tools in supporting the young women to counter the Islamophobia and gendered Islamophobia in their lives. Using these tools, however, as this paper argues, is not unproblematic and can reinscribe disempowering gender and ethno-cultural relations. Amid unprecedented gendered Islamophobia and the clear imperative of supporting Muslim women to access the tools of feminist ijtihad, the paper provides important insight into the possibilities and problematics of these tools.

Giving Muslim girls ‘a voice’: the possibilities and limits to challenging patriarchal interpretations of Islam in one English community

This paper presents the philosophies and practices of ‘Laura’, a young English community liaison worker and former religious studies teacher who has recently converted to Islam. Drawing on data generated from a qualitative and predominantly interview‐based research project that investigated issues of pedagogy and social justice in English schools, the focus is on Laura’s efforts to support Muslim girls through an Islamic discussion group. The paper highlights how Laura draws on Islamic beliefs to support the girls’ questioning of patriarchal interpretations of Islam within their Pakistani immigrant community. The paper also provides insight, however, into some of the tensions and limitations of Laura’s liberatory approach in terms of her positioning as white, western, and middle‐class. Against this backdrop, a self‐reflexive approach that is sensitive to how ‘ethnic‐specific sociability’ shapes understandings and enactments of gender is advocated. Such an approach is presented as central in considering how spaces of gender justice might be mobilised within community environments where unprecedented levels of multi‐cultural fragmentation and diversity have amplified tensions and conflict between and amongst racial and religious groups.

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.

Conceptualizing social influence in the ubiquitous computing era : technology adoption and use in multiple use contexts

Ubiquitous and mobile computing has increased the level of social connectedness. In an era where technology has permeated into spaces of work, play and socializing, social influence has become an important consideration. The operationalization of the social influence construct in the technology adoption and use literature often assumes singular technology use contexts and purposes. We question whether social influence, as operationalized in IS, is reflective of the utilitarian, hedonic and social environment that many individuals operate in. We propose a framework to consider social influence more inclusively, drawing on differences in referent power and levels of expertise. We outline our research approach within the demographic segment of young working professionals. Research in this area is necessary to improve theoretical explanations of adoptive behavior of these technologies. We hope to contribute by suggesting a richer, more encompassing operationalization of the social influence construct for future IS research.
