The response of complex ionized gas systems to the presence of nonuniform distribution of charged grains is investigated using a kinetic model. Contrary to an existing view that the electron temperature inevitably increases in the grain-occupied region because of enhanced ionization to compensate for the electrons lost to the grains, it is shown that this happens only when the ionizing electric field increases in the electron depleted region. The results for two typical plasma systems suggest that when the ionizing electric field depends on the spatially averaged electron density, the electron temperature in the grain containing region can actually decrease.

Firstly, on behalf of the secretariat that has coordinated these meetings every two years since 1985, our thanks to the organising committee here at the University of Economics in Cracow, Poland, for hosting this conference. I was asked to offer comment on the research agenda. There are many famous names to refer to. Two Australian colleagues here today are Peter Dowling and Helen De Cieri, longtime stalwarts of the field of IHRM. I acknowledge their contributions over many years, along with Randy Schuler and Denise Welch, and Dennis Briscoe. Other names such as Rosalie Tung, Pawan Bhudwhar, Michael Morley, Paul Sparrow and Wayne Cascio are known to us all. Their books have become classics. One example is the 700 page benchmark 2012 work by Chris Brewster and Wolfgang Mayrhofer, Handbook of Research on Comparative Human Resource Management (Brewster & Mayrhofer, 2012). More recently, in a book published by Cambridge University press in 2014, Mustafa Özbilgin, Dimitria Groutsis and William Harvey offer students a very accessible overview of the basics in IHRM (Ozbilgin, Groutsis, & Harvey, 2014). As for a research agenda, there are excellent literature reviews to which I would refer you, such as those by people who over the years have been frequent participants at this conference (Tarique & Schuler, 2010), (Farndale, Scullion, & Sparrow, 2010), and (Scullion & Collings, 2011).

The effect of plasmon oscillations on the DC tunnel current in a gold nanoisland thin film (GNITF) is investigated using low intensity P~1W/cm2 continuous wave lasers. While DC voltages (1–150 V) were applied to the GNITF, it was irradiated with lasers at different wavelengths (k¼473, 532, and 633 nm). Because of plasmon oscillations, the tunnel current increased. It is found that the tunnel current enhancement is mainly due to the thermal effect of plasmon oscillations rather than other plasmonic effects. The results are highly relevant to applications of plasmonic effects in opto-electronic devices.

This project characterised the bone microarchitecture of adult mice lacking the hormone, acyl ghrelin, by high resolution micro-computed tomography; and investigated the expression of the ghrelin axis in cells of human and mouse fetal cartilage. This thesis highlights for the first time the physiological role of the ghrelin axis in the bone microenvironment of aged mice. Furthermore it improves our understanding of the complex expression patterns of the ghrelin axis in cartilage cells of human and mouse fetal skeletons.

This thesis is a population-based ecological study designed to investigate the issue of mortality displacement (or "harvesting" effect) in the assessment of temperature-related deaths in Brisbane, Australia. It examines the temperature impacts on mortality, and assesses the harvesting effects on the temperature–related deaths. This study contributes to the knowledge base of understanding the temperature-mortality relationship and assists in formulating and evaluating public health intervention strategies within the context of climate change.

As a social species in a constantly changing environment, humans rely heavily on the informational richness and communicative capacity of the face. Thus, understanding how the brain processes information about faces in real-time is of paramount importance. The N170 is a high temporal resolution electrophysiological index of the brain's early response to visual stimuli that is reliably elicited in carefully controlled laboratory-based studies. Although the N170 has often been reported to be of greatest amplitude to faces, there has been debate regarding whether this effect might be an artifact of certain aspects of the controlled experimental stimulation schedules and materials. To investigate whether the N170 can be identified in more realistic conditions with highly variable and cluttered visual images and accompanying auditory stimuli we recorded EEG 'in the wild', while participants watched pop videos. Scene-cuts to faces generated a clear N170 response, and this was larger than the N170 to transitions where the videos cut to non-face stimuli. Within participants, wild-type face N170 amplitudes were moderately correlated to those observed in a typical laboratory experiment. Thus, we demonstrate that the face N170 is a robust and ecologically valid phenomenon and not an artifact arising as an unintended consequence of some property of the more typical laboratory paradigm.

Presented in concept at the ACUADS 2008 conference, this paper reports on a research study conducted for PhD into how artistic researchers have been accommodated in the Australian university research management system, and the impacts experienced by artistic researchers through this location. It draws upon a wide range of data to provide the first analysis of this topic reported across all artistic disciplines in Australia in relation to university experiences and updates the Strand Report in 1998 in relation to government policy. Data sources include a correlation of literature from arts disciplines with that of higher education management and government policies; survey responses from of heads of academic units containing artistic researchers in over 40% of Australian universities; interviews with 27 artistic researchers in three case study universities; and interviews with longstanding expert commentators on artistic research and Deputy Vice Chancellors responsible for research. The study suggests that while limited progress has been made towards the acceptance of artistic research as an equivalent and legitimate research endeavour, significant structural, cultural and practical challenges remain which are undermining relationships between universities and their artistic staff and engendering behavioural changes within artistic practitioners that can affect the nature and quality of artistic work that is produced. Reflecting the voices of artistic researchers across the broad visual and performing arts disciplinary spectrum from early to senior career academics, it explores ways forward for universities, and artistic researchers themselves, to secure greater equity and recognition for artistic research.

The Haddon Matrix was developed in the 1960s road safety arena, and has since been used in many public health settings. The literature and two specific case studies are reviewed to describe the background to the Haddon Matrix, identify how it has been critiqued and developed over time and practical applications in the work-related road safety context. Haddon’s original focus on the road, vehicle and driver has been extended and applied to include organisational safety culture, journey management and wider issues in society that affect occupational drivers and the communities in which they work. The paper shows that the Haddon Matrix has been applied in many projects and contexts. Practical work-related road safety applications include providing a comprehensive systems-based safety management framework to inform strategy. It has also been used to structure the review or gap analysis of current programs and processes, identify and develop prevention measures and as a tool for effective post-event investigations.

Entrepreneurship Programs and the Modern University is an excellent resource for those who intend to set up an entrepreneurship program or centre, and arguably even more so for those who wish to coordinate or expand such activities into an effective "entrepreneurship eco-system" across the university and its external stakeholders. Morris, Kuratko, and Cornwall's intention in writing this book is to "advocate a more strategic and integrative framework for building the curricular, co-curricular, research, community engagement, and infrastructure components of a program" (p. xii).

This study compared optics of eyes in people with diabetes with those age-balanced controls. Relative to the control group, the diabetes group demonstrated greater lens thickness, more curved lens shapes, smaller lens diameters, higher light scatter, greater lens yellowing, and poorer focusing ability. While the optics of the people with diabetes made them appear as older eyes than those of people of the same age without diabetes, the differences did not increase significantly with age. It was concluded that age-related changes in eyes of people with diabetes need not be accelerated if the diabetes is well controlled.
