Chinese market has been a highly preferred market for many organisations worldwide in the past twenty years. However, it is not an easy market to penetrate. Australian companies are among those Europeans and Americans who have been tackling the market with little positive results. One primary reason is that they do not appreciate the important role and impact of Chinese culture.

We have used the hypothalamo-pituitary disconnected (HPD) sheep model to investigate direct pituitary actions of cortisol to suppress LH secretion in response to exogenous GnRH. We previously observed that, during the non-breeding season, treatment with cortisol did not suppress the LH response to GnRH in HPD gonadectomised rams or ewes.1 In the present experiment, we tested the effect of cortisol on the LH response to exogenous GnRH in gonadectomised HPD sheep during the breeding season. Using a cross-over design, HPD gonadectomised Romney Marsh rams (n = 6) and ewes (n = 5) received a saline or cortisol (250 μg/kg/h) infusion for 30 h on each of two days, one week apart. All animals were treated with 125 ng i.v. injections of GnRH every 2 h during a 6 h control period preceding the infusion and during the infusion. Jugular blood samples were taken during the control period and the first 6 h and last 6 h of the infusion (over 3 LH pulses). Mean plasma concentrations of LH and LH pulse amplitudes, driven by programmed GnRH injections, were similar in gonadectomised rams and ewes and there were no significant effects of saline infusion between the control periods or the saline infusion in either sex. The amplitude of LH pulses was significantly (P < 0.05) reduced in rams during the first 6 h of the cortisol infusion compared to the control period, but there were no effects of the cortisol infusion in ewes. These data show that, in the absence of sex steroids, there is a sex difference in the mechanism by which cortisol acts at the pituitary to reduce LH secretion in response to exogenous GnRH in HPD gonadectomized sheep during the breeding season. We conclude that the effect of cortisol to reduce secretion of LH involves an action on the pituitary, at least in gonadectomised rams.

Academic staff play a fundamental role in the use of online learning by students. Yet, compared to studies reporting student perspectives on online learning, studies investigating the perspectives of academic staff are much more limited. Perhaps the least common investigations are those that compare the perceptions of academic staff and students using the same online learning environment (OLE). Much research indicates, at least initially, academic staff most value OLE systems as a mechanism for efficient delivery of learning materials to students. Following the mainstreaming of an OLE at Deakin University in 2004, the data from a large, repeated, representative and quantitative survey were analysed to investigate comparative staff and student evaluations of an OLE, and to explore the evidence for development in the use of an OLE by academic staff. Generally, students were found to give higher importance and satisfaction ratings to elements of the OLE than staff. Students were also more likely than staff to agree that the OLE enhanced their learning. A comparison of the mean ratings recorded for staff in 2004 and 2005 showed that both importance and satisfaction ratings of elements of the OLE were almost universally higher after a year of use of the OLE.

The current paper provides a detailed examination of the psychometric properties of the Gudjonsson Suggestibility Scales (Gudjonsson, 1997) which have been widely used to measure individual suggestibility. Several fundamental problems associated with the Shift and Total Suggestibility subscales are identified and discussed. Two arguably more conceptually coherent methods of scoring the Shift subscale (‘Shift-positive’ and ‘Shift-negative’) are introduced. A confirmatory factor analytic model based on two oblique factors and relative answering regression effects between corresponding items was tested and supported based on a sample of 220 children. Based on a latent variable estimation approach, the internal consistency reliabilities associated with the Shift subscale scores were found to be unacceptably low. Consequently, we propose that until the problems associated with Shift-standard and Total Suggestibility is addressed successfully, use of the GSS should be limited to the Yield subscale.

With the waning of state-sponsored multiculturalism, local governments in Australia have assumed leadership and responsibility for establishing and maintaining collaborative relationships with stakeholders to promote diverse and inclusive cities. Engaging with residents often through consultation processes and interacting with key institutions, local governments aim to value local knowledge and mobilise citizen participation. This social interactive approach to building local knowledge in places officially and popularly identified as socially disadvantaged and culturally diverse, however, is fraught with interethnic tensions if cultural practices unintentionally priviÌege whiteness. In this paper I argue that such tensions can also give rise to moments of affective ambivalence that ate productive if it leads to the acknowledgement and questioning of white privilege within the formal agencies of government. Such questioning provides the possibility to value the voices of local residents and engage in meaningful intercultural dialogue. This paper draws on indepth interviews with planners, elected local councillors and residents in the City of Greater Dandenong, Melbourne, to illustrate the potential that the affective dimension of living with cultural diversity has in building governance capacity and inclusive understandings of citizenship.

This thesis examines short fiction and some poetry by writers from four different Australian cultural communities, the Indigenous community, and the Jewish, Chinese and Middle-Eastern communities. I have chosen to study the most recent short fiction available from a selection of writing which originates from each culture. In the chapters on Chinese-Australian and Middle-Eastern Australian fiction I have examined some poetry if it contributes to the subject matter under discussion. In this study I show how the short story form is used as a platform for these writers to express views on their own cultures and on their identity within Australian society. Through a close examination of texts this study reveals the strategies by which many of these narratives provide an imaginative literary challenge to Anglo-Celtic cultural dominance, a challenge which contributes to the political nature of this writing and the shifting nature of the short story genre. This study shows that by celebrating difference these narratives can act as a site of resistance and show a capacity to reflect and instigate cultural change. This thesis examines the process by which these narratives create a dialogue between cultures and address the problems inherent in diverse cultural communities living together.

This study focuses on the experiences of a group of educators engaged in a professional development program by distance education in Papua New Guinea. The participants in this study have been keeping professional journals, for periods of up to three years, about their experiences of distance education. Their discourses have been used to form a ‘connected group’ of research participants, who use an action framework to focus on problematic issues surrounding distance education in Papua New Guinea. It is a piece of research, framed by critical theory, and characterised by participation, collaboration, reflexivity, reciprocity and empowerment. The process of the study is based in dialogue, and takes the view that research is constituted of a transformative perspective, which alters the way research participants understand the multiple realities in which they live and work, arid ultimately results in improvements in their lived experiences. The nature of the methodology privileges Voice' and a discourse of difference from each participant which contributes to the problematic nature of the study. The study has concerned itself, increasingly, with issues of power and control in the research process, and this has resulted in significant changes in the research as participants have become more conscious of issues such as distance, dialogue and difference. The study has evolved over a period of time in significant ways, and evidence is available that teachers in Papua New Guinea, despite structural and pedagogical barriers, are critically reflective and are able to transform their practice in ways which are consistent with social, cultural and political contexts in which they live and work. A number of 'local1 theories about research and distance education in Papua New Guinea are developed by the participants as they become informed about issues during the research. The practice of distance education and professional development, at personal and institutional levels, undergoes reconstruction during the life of the research and the study 'signals' other ways in which distance education and professional development may be reconstructed in Papua New Guinea.

The thesis reviews the literature relating to girls and computing within a framework which is structured around three specific questions. First, are there differences between girls and boys in their participation in class computing activities and/or in non-class computing activities? Second, do these differences in participation in computing activities have broader implications which justify the growing concern about the under-representation of girls? Third, wahy are girls under-represented in these activities? Although the available literature is predominantly descriptive, the underlying implicit theoretical model is essentially a social learning model. Girl's differential participation is attributed to learned attitudes towards computing rathan to differences between girls and boys in general ability. These attitudes, which stress the masculine, mathematical, technological aspects of computing are developed through modelling, direct experience, intrinsic and extrinsic reinforcement and generalisation from pre-existing, attitudes to related curriculum areas. In the literature it is implicitly assumed that these attitudes underlie girl's decisions to self-select out of computing activities. In this thesis predictions from a social learning model are complemented by predictions derived from expectancy-value, cognitive dissonance and self-perception theories. These are tested in three separate studies. Study one provides data from a pretest-posttest study of 24 children in a year four class learning BASIC. It examines pre- and posttest differences between girls and boys in computing experience, knowledge and achievement as well as the factors relating to computing achievement. Study two uses a pretest-posttest control group design to study the gender differences in the impact of the introduction of Logo into years 1, 3, 5 and 7 in both a coeducational and single-sex setting using a sample of 222 children from three schools. Study three utilises a larger sample of 1176 students, drawn from three secondary schools and five primary schools, enabling an evaluation of gender differences in relation to a wide range of class computing experiences and in a broader range of school contexts. The overall results are consistent across the three studies, supporting the contention that social factors, rather than ability differences influence girls' participation and achievement in computing. The more global theoretical framework, drawing on social learning, expectancy-value, cognitive dissonance and self-perception theories, provides a more adequate explanation of gender differences in participation than does any one of these models.

A professional development (Summer School) with over two hundred teachers of English participating in the activity for over six months, was supported by an online social software website. The employment of Web 2.0 technologies to facilitate the delivery of the summer school was reasonably successful, but other benefits were realised. This poster presentation will show how scaffolded learning along with new experiences and knowledge, can potentially have added long-term value when sustained in an authentic, supportive learning environment.

Debates about multiculturalism are common to many late-modern societies today. Globalization has triggered a massive flow of people across state borders, challenging and changing assumptions about national identities and cultural politics. How to deal with difference without reducing it to sameness is becoming one of the main issues discussed by policy-makers, researchers and educators. This paper argues for the importance of turning to dialogical ethics before developing and implementing largescale political strategies in managing differences. It draws on the ideas of Bakhtin and Levinas to transcend the notion of ‘caring at a distance’ that is embedded in the neo-liberal construction of moral selfhood. As an alternative, the emphasis is made on spatial proximity – on ‘face-to-face’ relations with alterity – to conceptualize the dialogical self who is both responsive to and responsible for the Other. Bakhtin’s philosophy of the act and Levinas’ ethics of responsibility are mutually enriching in thinking about the role of the dialogical self in building a pluralistic society. The paper concludes with the implications of dialogical ethics for multicultural education.

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.
