Entrepreneurial growth : the role of international knowledge acquisition as moderated by firm age

In line with repeated recent calls for research on specific forms of growth rather than on an undifferentiated notion of “total growth,” our study contributes to the understanding of entrepreneurial growth. By this we mean growth through expansion into new geographic markets and/or via the introduction of new products or services. Building on Penrose's theory of the growth of the firm and on the research streams she has in part inspired, we investigate the impact of knowledge acquisition from international markets on entrepreneurial growth both at home and abroad. We further suggest that the effects of international knowledge acquisition on entrepreneurial growth will vary with firm age. Utilizing longitudinal data on 138 small and medium-sized enterprises (SMEs), we find that the acquisition of knowledge from international markets fuels growth through market development, and that this effect is stronger for international expansion than domestic expansion. Our results also show that firm age negatively moderates the relationship between international knowledge acquisition and entrepreneurial growth via the introduction of new products or services. Specifically, international knowledge acquisition has a positive effect on growth via new products/services development in young firms, but a negative effect in mature firms. We assume this reflects changes over time in how international knowledge is managed.

The duration of Chlamydia muridarum genital tract infection and associated chronic pathological changes are reduced in IL-17 knockout mice but protection is not increased further by immunization

IL-17 is believed to be important for protection against extracellular pathogens, where clearance is dependent on neutrophil recruitment and local activation of epithelial cell defences. However, the role of IL-17 in protection against intracellular pathogens such as Chlamydia is less clear. We have compared (i) the course of natural genital tract C. muridarum infection, (ii) the development of oviduct pathology and (iii) the development of vaccine-induced immunity against infection in wild type (WT) BALB/c and IL-17 knockout mice (IL-17-/-) to determine if IL-17-mediated immunity is implicated in the development of infection-induced pathology and/or protection. Both the magnitude and duration of genital infection was significantly reduced in IL-17-/- mice compared to BALB/c. Similarly, hydrosalpinx was also greatly reduced in IL-17-/- mice and this correlated with reduced neutrophil and macrophage infiltration of oviduct tissues. Matrix metalloproteinase (MMP) 9 and MMP2 were increased in WT oviducts compared to IL-17-/- animals at day 7 post-infection. In contrast, oviducts from IL-17-/- mice contained higher MMP9 and MMP2 at day 21. Infection also elicited higher levels of Chlamydia-neutralizing antibody in serum of IL-17-/- mice than WT mice. Following intranasal immunization with C. muridarum Major Outer Membrane Protein (MOMP) and cholera toxin plus CpG adjuvants, significantly higher levels of chlamydial MOMP-specific IgG and IgA were found in serum and vaginal washes of IL-17-/- mice. T cell proliferation and IFNγ production by splenocytes was greater in WT animals following in vitro re-stimulation, however vaccination was only effective at reducing infection in WT, not IL-17-/- mice. Intranasal or transcutaneous immunization protected WT but not IL-17-/- mice against hydrosalpinx development. Our data show that in the absence of IL-17, the severity of C. muridarum genital infection and associated oviduct pathology are significantly attenuated, however neither infection or pathology can be reduced further by vaccination protocols that effectively protect WT mice.

International acclaim : the role(s) of the international film festival in supporting emerging women’s cinema

International Film Festivals act as important sites for the exhibition of contemporary world cinema. Film festivals represent an increasingly transnational film culture, where audiences, filmmakers, distributors, press, critics and academics come together from all over the world to discover new films, network with one another and debate about the past, present and future of cinema. This research project investigates the role that international film festivals play within the wider international film industry, with a specific focus on emerging women filmmakers. It therefore explores the arena of contemporary women.s cinema at its intersection with the international film festival industry. The significance and original contribution of the research is its intervention in the growing field of film festival studies through a specific investigation of how international film festivals support emerging women filmmakers. The positioning of the research at the intersection of feminist film theory and festival research within the broader context of transnational cinema allows the examination of each festival, the attending filmmakers and their films to be addressed within a more refined and nuanced lens. A core method for the thesis is the close textual analysis of particular emerging women filmmakers. films which are screened at the respective festivals. The research also utilises the qualitative research strategies of the case study and the interview to ¡°seek to understand the context or setting of the participants through visiting this context and gathering information personally¡± (Creswell 2003, 9). The textual analysis is used in dialogue with the interviews and the participant observational data gathering to provide a related context for understanding these films and their cultural meanings, both personally for the filmmaker and transnationally across the festival circuit. The focus of the case studies is the Brisbane International Film Festival, the International Film Festival Rotterdam and the Toronto International Film Festival. These three festivals were chosen for their distinct geographical locations in the Asia Pacific, Europe and North America, as well as for their varying size and influence on the international film festival circuit. Specifically, I investigate the reasons behind why the organisers of a particular festival have chosen a certain woman.s film, how it is then packaged or displayed within the programme, and how all of this impacts on the filmmaker herself. The focus of my research is to investigate film festivals and their .real-life. applications and benefits for the filmmakers being supported, both through the exhibition of their films and through their attendance as festival guests. The research finds that the current generation of emerging women filmmakers has varying levels of experience and success at negotiating the international film festival circuit. Each of the three festivals examined include and promote the films of emerging women filmmakers through a range of strategies, such as specific programming strands dedicated to showcasing emerging talent, financial support through festival funds, providing visibility within the programme, exposure to international audiences and networking opportunities with industry professionals and other filmmakers. Furthermore, the films produced by the emerging women filmmakers revealed a strong focus on women.s perspectives and experiences, which were explored through the interweaving of particular aesthetic and cinematographic conventions.

Protocol for a randomised blocked design study using telephone and text-messaging to support cardiac patients with diabetes : a cross cultural international collaborative project

Background The prevalence of type 2 diabetes is rising internationally. Patients with diabetes have a higher risk of cardiovascular events accounting for substantial premature morbidity and mortality, and health care expenditure. Given healthcare workforce limitations, there is a need to improve interventions that promote positive self-management behaviours that enable patients to manage their chronic conditions effectively, across different cultural contexts. Previous studies have evaluated the feasibility of including telephone and Short Message Service (SMS) follow up in chronic disease self-management programs, but only for single diseases or in one specific population. Therefore, the aim of this study is to evaluate the feasibility and short-term efficacy of incorporating telephone and text messaging to support the care of patients with diabetes and cardiac disease, in Australia and in Taiwan. Methods/design A randomised controlled trial design will be used to evaluate a self-management program for people with diabetes and cardiac disease that incorporates the use of simple remote-access communication technologies. A sample size of 180 participants from Australia and Taiwan will be recruited and randomised in a one-to-one ratio to receive either the intervention in addition to usual care (intervention) or usual care alone (control). The intervention will consist of in-hospital education as well as follow up utilising personal telephone calls and SMS reminders. Primary short term outcomes of interest include self-care behaviours and self-efficacy assessed at baseline and four weeks. Discussion If the results of this investigation substantiate the feasibility and efficacy of the telephone and SMS intervention for promoting self management among patients with diabetes and cardiac disease in Australia and Taiwan, it will support the external validity of the intervention. It is anticipated that empirical data from this investigation will provide valuable information to inform future international collaborations, while providing a platform for further enhancements of the program, which has potential to benefit patients internationally.

Understanding VET teachers' dilemmas in providing quality education to international students in Brisbane

In the past fifteen years, increasing attention has been given to the role of Vocational Education and Training (VET) in attracting large numbers of international students and its contribution to the economic development of Australia. This trend has given rise to many challenges in vocational education, especially with regard to providing quality education that ensures international students' stay in Australia is a satisfactory experience. Teaching and learning is continuously scrutinized, teaching quality and student assessment are subject to regular audit (Takerei, 2010). VET teachers are key stakeholders in international education and share responsibility for ensuring international students gain quality learning experiences and positive outcomes, however, their experiences are generally not well understood. Therefore, this thesis, investigates particular challenges and associated dilemmas that VET teachers experience when teaching international students. The research participants were 15 teachers from several public and private VET institutions in Brisbane, Australia. The method involved responsive interviewing and inductive data analysis to identify and categorize teachers' challenges and dilemmas. The research reveals qualitatively different ways in which the 15 VET educators experienced challenges and associated dilemmas in their culturally diverse teaching context. The research shows that VET teachers experience numerous challenges and various inter-related professional, educational and personal dilemmas. These dilemmas result from ethical tensions teachers experience in their interactions with international students, teaching colleagues and their employment institutions. The dilemmas are often influenced by current economic and political conditions of international education. The dilemmas raised in the study by 15 VET teachers might be familiar to other teachers in VET and universities but to date they have received limited attention by researchers. This study's findings indicate significant implications for VET teachers, students, VET institutions and the government at a time of rapid economic, political, cultural and educational change. The findings are of potential interest to VET policy makers, managers and teachers. By giving voice to VET teachers, who are key stakeholders in the sustainability and future growth of VET, they contribute evidence for ongoing review and development of quality learning and teaching in the culturally diverse VET sector.

System level tests of transformer differential protection using an IEC 61850 process bus

The IEC 61850 family of standards for substation communication systems were released in the early 2000s, and include IEC 61850-8-1 and IEC 61850-9-2 that enable Ethernet to be used for process-level connections between transmission substation switchyards and control rooms. This paper presents an investigation of process bus protection performance, as the in-service behavior of multi-function process buses is largely unknown. An experimental approach was adopted that used a Real Time Digital Simulator and 'live' substation automation devices. The effect of sampling synchronization error and network traffic on transformer differential protection performance was assessed and compared to conventional hard-wired connections. Ethernet was used for all sampled value measurements, circuit breaker tripping, transformer tap-changer position reports and Precision Time Protocol synchronization of sampled value merging unit sampling. Test results showed that the protection relay under investigation operated correctly with process bus network traffic approaching 100% capacity. The protection system was not adversely affected by synchronizing errors significantly larger than the standards permit, suggesting these requirements may be overly conservative. This 'closed loop' approach, using substation automation hardware, validated the operation of protection relays under extreme conditions. Digital connections using a single shared Ethernet network outperformed conventional hard-wired solutions.

A model for research supervision of international students in engineering and information technology disciplines

A large proportion (over 12 per cent) of international and non-English speaking background (NESB) postgraduate research students enrol in engineering and information technology (IT) programs in Australian universities. They find themselves in an advanced research culture, and are technically and scientifically challenged early in their programs. This is in addition to cultural, social and religious isolation and linguistic barriers they have to contend with. The project team surveyed this cohort at QUT and UWA, on the hypothesis that they face challenges that are more discipline-specific. The results of the survey indicate that existing supervisory frameworks which are limited to linguistic contexts are not fully assisting these students and supervisors to achieve high quality research. The goal of this project is to extend these supervisory frameworks to a holistic model that will address the unique needs and supervisory issues these students face in engineering and IT disciplines. The model will be useable by all other Australian universities.

The supervision tango : perceptions of supervisors of international graduate students in Engineering and IT

This paper, which was part of a larger study, reports on a survey that explored the perceptions of 69 graduate supervisors regarding issues in supervision from three higher education institutions in Australia. Factors that contribute to student success in higher education research degrees are many and diverse, including a complex dance of student factors, supervisor factors, and their supervisory context factors, and those informed by cultural and language differences. Therefore, a complex system approach using Bayesian network modelling was used to explore how student and/or supervisor factors influence the success of culturally and linguistically diverse (CALD) graduate students in Engineering and IT. Findings suggest that key factors include the experience of supervisors in terms of experience with the Australian higher education system, personal cross-cultural experience.

International assessments of science learning : their positive and negative contributions to science education

The establishment and continuity of two international comparative assessments of science learning—the IEA’s TIMSS project and the OECD’s PISA project—have meant that there are now high-status reference points for other national and more local approaches to assessing the efficacy of science teaching and learning. Both projects, albeit with very different senses of what the outcome of science learning should be, have contributed positively and negatively to the current state of assessment of school science. The TIMSS project looks back at the science that is commonly included in the curricula of the participating countries. It is thus not about established school science nor about innovations in it. PISA is highly innovative looking, prospectively forward to see how students can use their science learning in everyday life situations. In this chapter some of these positives and negatives are discussed.
