Public engagement is a defining feature of collaborative approaches to environmental management (Petts 2006, Whelan and Oliver 2005). Public engagement in this context is focused on incorporating residents and communities of interest in activities like ecological restoration, catchment management, and environmental conservation in a wide range of situations (Nelson and Pettit 2004, Petts 2007). Some authors consider public engagement to be a sign of healthy democratic functioning in society (Skocpol and Fiorina 1999). Others draw attention to overcoming widely noted practical limitations of top-down mechanisms, emphasising that public engagement results in programs being implemented more effectively (Broderick 2005, Leach et al. 1999).

Numerous studies have documented subtle but consistent sex differences in self-reports and observer-ratings of five-factor personality traits, and such effects were found to show well-defined developmental trajectories and remarkable similarity across nations. In contrast, very little is known about perceived gender differences in five-factor traits in spite of their potential implications for gender biases at the interpersonal and societal level. In particular, it is not clear how perceived gender differences in five-factor personality vary across age groups and national contexts and to what extent they accurately reflect assessed sex differences in personality. To address these questions, we analyzed responses from 3,323 individuals across 26 nations (mean age = 22.3 years, 31% male) who were asked to rate the five-factor personality traits of typical men or women in three age groups (adolescent, adult, and older adult) in their respective nations. Raters perceived women as slightly higher in openness, agreeableness, and conscientiousness as well as some aspects of extraversion and neuroticism. Perceived gender differences were fairly consistent across nations and target age groups and mapped closely onto assessed sex differences in self- and observer-rated personality. Associations between the average size of perceived gender differences and national variations in sociodemographic characteristics, value systems, or gender equality did not reach statistical significance. Findings contribute to our understanding of the underlying mechanisms of gender stereotypes of personality and suggest that perceptions of actual sex differences may play a more important role than culturally based gender roles and socialization processes.

At a time when theatre practitioners and companies are concerned with dwindling audience numbers, funding and interest (so what’s new?), what this paper discusses is less about theatre ‘changing direction’ and more about ‘changing theatre Direction’. A subtle semantic shift perhaps but one which has proven enormously useful over 25 years as a professional creator, director, performer, designer and teacher for stage, screen – and other contexts. Applying theatrical skills to apparently unrelated contexts is not new, however it bears re-examining. My own experience as a ‘directorial specialist’ in mime and movement confirms the fundamental theatricality in all human communication – whether stage, screen, auditorium or meeting room – I would argue that there is no professional context completely devoid of some measure of ‘performance’. And if you’re going to do performance, however minutely, subtly and in whatever context, at least make it the best performance you can by ‘directing it’. This paper examines the adaptation of theatre direction to other contexts and discusses:- • which other contexts • directing non-performers • what theatre direction provides

The chlamydiae are obligate intracellular parasites that have evolved specific interactions with their various hosts and host cell types to ensure their successful survival and consequential pathogenesis. The species Chlamydia pneumoniae is ubiquitous, with serological studies showing that most humans are infected at some stage in their lifetime. While most human infections are asymptomatic, C. pneumoniae can cause more-severe respiratory disease and pneumonia and has been linked to chronic diseases such as asthma, atherosclerosis, and even Alzheimer's disease. The widely dispersed animal-adapted C. pneumoniae strains cause an equally wide range of diseases in their hosts. It is emerging that the ability of C. pneumoniae to survive inside its target cells, including evasion of the host's immune attack mechanisms, is linked to the acquisition of key metabolites. Tryptophan and arginine are key checkpoint compounds in this host-parasite battle. Interestingly, the animal strains of C. pneumoniae have a slightly larger genome, enabling them to cope better with metabolite restrictions. It therefore appears that as the evolutionarily more ancient animal strains have evolved to infect humans, they have selectively become more "susceptible" to the levels of key metabolites, such as tryptophan. While this might initially appear to be a weakness, it allows these human C. pneumoniae strains to exquisitely sense host immune attack and respond by rapidly reverting to a persistent phase. During persistence, they reduce their metabolic levels, halting progression of their developmental cycle, waiting until the hostile external conditions have passed before they reemerge.

One of the most significant activities induced by interferon-gamma against intracellular pathogens is the induction of IDO (indoleamine 2,3-dioxygenase) expression, which subsequently results in the depletion of tryptophan. We tested the hypothesis that human strains of Chlamydia pneumoniae are more sensitive to tryptophan limitation than animal C. pneumoniae strains. The human strains were significantly more sensitive to IFN-γ than the animal strains in a lung epithelia cell model (BEAS-2B), with exposure to 1 U ml(-1) IFN-γ resulting in complete loss of infectious yield of human strains, compared to the animal strains where reductions in infectious progeny were around 3.5-4.0 log. Strikingly, the IFN-γ induced loss of ability to form infectious progeny production was completely rescued by removal of the IFN-γ and addition of exogenous tryptophan for the human strains, but not the animal strains. In fact, a human heart strain was more capable of entering a non-infectious, viable persistent stage when exposed to IFN-γ and was also more effectively rescued, compared to a human respiratory strain. Exquisite susceptibility to IFN-γ, specifically due to tryptophan availability appears to be a core adaptation of the human C. pneumoniae strains, which may reflect the chronic nature of their infections in this host.

This paper investigates demodulation of differentially phase modulated signals DPMS using optimal HMM filters. The optimal HMM filter presented in the paper is computationally of order N3 per time instant, where N is the number of message symbols. Previously, optimal HMM filters have been of computational order N4 per time instant. Also, suboptimal HMM filters have be proposed of computation order N2 per time instant. The approach presented in this paper uses two coupled HMM filters and exploits knowledge of ...

This paper examines two concepts which are central to contemporary standard setting in occupational health and safety (OHS) regulation, and explores the differences and similarities between these concepts – the notion of ‘reasonably practicable’ which qualifies the ‘general duties’ and some other provisions in the Australian OHS standards, and the risk management requirements typically found in OHS regulations and approved codes of practice (advisory standards in Queensland).

Information Technology (IT) value is amongst the most important concepts in the Information Systems (IS) research field. Yet, a clear, well-formulated conceptualization of IT value, cumulatively built upon, is lacking. Drawing from the Facet Theory literature, this paper broaches several meta-theoretical considerations addressing an “ideal” conceptualization of IT value. We argue these considerations may shed light on the advancement of IT value conceptualization methodology.

This thesis has made a significant contribution to future chlamydial research by uncovering the chlamydial pathogenic mechanisms which will potentially help in the development of targeted vaccine against the pathogen. This thesis has made important new contributions to our understanding of Chlamydia pneumoniae specific adaptations to stress responses and has provided new perspectives on the survival of this successful pathogen. This thesis has used two well established microbial stressors and has identified major differences in stress responses between human and animal Chlamydia pneumoniae isolates.

Redclaw crayfish, Cherax quadricarinatus, possess a number of biological and commercial attributes that make them ideal for commercial aquaculture. While some studies have investigated digestive enzyme activity and nutritional requirements of this species, little information exists about the expression of digestive enzyme genes and their role in regulating digestive capacity. The current study therefore sequenced and annotated a RNASeq library constructed from a redclaw hepatopancreas to identify genes involved in digestive enzyme production. We observed that most of the transcripts that were annotated as digestive enzyme genes are associated with carbohydrate metabolism, thus confirming that redclaw have an innate capacity to digest a range of carbohydrate substrates. While endoglucanases were the most abundant group of digestive enzymes found, a number of novel transcripts were also detected. Here, we provide the first report for the presence and expression of endo-b-mannanase in freshwater crayfish. This novel gene showed significant alignment with a GH5 family protein from marine Limnoriids, wood borers that do not possess symbiotic microbes in their gut system. Overall, the data generated here provide an important resource to better understand the suite of digestive enzymes in redclaw that are very useful to fully utilize the species’ digestive capacity and will assist development of specific artificial feeds.

Stephen Gray is a writer and law lecturer who has been living in Darwin since 1989. He started out writing formal legal pieces about how copyright law had unsuccessfully sought to accommodate Aboriginal art. Such work led him to further investigate the philosophical questions underlying the legal issues affecting both traditional and urban Indigenous people. Gray has also explored matters of bioprospecting in relation to Indigenous biological resources. He has investigated the introduction of a label of authenticity into Australia. Gray has also published a number of articles about other legal issues affecting Indigenous people. He has explored such topics as native title, customary law, alternative dispute resolution, and criminal law. Gray has recently been awarded The Australian/ Vogel Literary Award for his novel The Artist is a Thief. He was inspired to write a book after being sent out to a community on a possible copyright claim as part of his job in the law faculty of Northern Territory University: "I wrote an academic article and then a more philosophical piece talking about the copyright act and the way it doesn't really protect traditional artists who have a very different view of the place of their art. The pieces were interesting, but I felt there was something more there that needed a fictional expression as well." It is ironic that such a self-conscious and sophisticated meditation upon appropriation and authenticity should win The Australian/ Vogel Literary Award. The inaugural award in 1980 was won by Paul Radley, who later revealed his books were mostly written by his uncle, and in 1993 it was won by Helen Demidenko, aka Darville, who had lied about her Ukrainian background and family history.
