Non-state insurgent actors are too weak to compel powerful adversaries to their will, so they use violence to coerce. A principal objective is to grow and sustain violent resistance to the point that it either militarily challenges the state, or more commonly, generates unacceptable political costs. To survive, insurgents must shift popular support away from the state and to grow they must secure it. State actor policies and actions perceived as illegitimate and oppressive by the insurgent constituency can generate these shifts. A promising insurgent strategy is to attack states in ways that lead angry publics and leaders to discount the historically established risks and take flawed but popular decisions to use repressive measures. Such decisions may be enabled by a visceral belief in the power of coercion and selective use of examples of where robust measures have indeed suppressed resistance. To avoid such counterproductive behaviours the cases of apparent 'successful repression' must be understood. This thesis tests whether robust state action is correlated with reduced support for insurgents, analyses the causal mechanisms of such shifts and examines whether such reduction is because of compulsion or coercion? The approach is founded on prior research by the RAND Corporation which analysed the 30 insurgencies most recently resolved worldwide to determine factors of counterinsurgent success. This new study first re-analyses their data at a finer resolution with new queries that investigate the relationship between repression and insurgent active support. Having determined that, in general, repression does not correlate with decreased insurgent support, this study then analyses two cases in which the data suggests repression seems likely to be reducing insurgent support: the PKK in Turkey and the insurgency against the Vietnamese-sponsored regime after their ousting of the Khmer Rouge. It applies 'structured-focused' case analysis with questions partly built from the insurgency model of Leites and Wolf, who are associated with the advocacy of US robust means in Vietnam. This is thus a test of 'most difficult' cases using a 'least likely' test model. Nevertheless, the findings refute the deterrence argument of 'iron fist' advocates. Robust approaches may physically prevent effective support of insurgents but they do not coercively deter people from being willing to actively support the insurgency.

Overexpression of the receptor tyrosine kinase EphB4 is common in epithelial cancers and linked to tumor progression by promoting angiogenesis, increasing survival and facilitating invasion and migration. However, other studies have reported loss of EphB4 suggesting a tumor suppressor function in some cancers. These opposing roles may be regulated by (i) the presence of the primary ligand ephrin-B2 that regulates pathways involved in tumor suppression or (ii) the absence of ephrin-B2 that allows EphB4 signaling via ligand-independent pathways that contribute to tumor promotion. To explore this theory, EphB4 was overexpressed in the prostate cancer cell line 22Rv1 and the mammary epithelial cell line MCF-10A. Overexpressed EphB4 localized to lipid-rich regions of the plasma membrane and confirmed to be ligand-responsive as demonstrated by increased phosphorylation of ERK1/2 and internalization. EphB4 overexpressing cells demonstrated enhanced anchorage-independent growth, migration and invasion, all characteristics associated with an aggressive phenotype, and therefore supporting the hypothesis that overexpressed EphB4 facilitates tumor promotion. Importantly, these effects were reversed in the presence of ephrin-B2 which led to a reduction in EphB4 protein levels, demonstrating that ligand-dependent signaling is tumor suppressive. Furthermore, extended ligand stimulation caused a significant decrease in proliferation that correlated with a rise in caspase-3/7 and -8 activities. Together, these results demonstrate that overexpression of EphB4 confers a transformed phenotype in the case of MCF-10A cells and an increased metastatic phenotype in the case of 22Rv1 cancer cells and that both phenotypes can be restrained by stimulation with ephrin-B2, in part by reducing EphB4 levels.

This conference paper reports on the findings of the 'Vulnerability and the News Media’ project about news reporting on communities that are commonly regarded as ‘vulnerable’ by virtue of their issues or circumstances. The project focuses on news reporting of Indigenous and ethnically diverse communities, as well as people affected by mental health issues, people with disabilities, and survivors of crime and traumatic events. Numerous educational initiatives have tried to improve the quality of media reports about these communities and their issues. Despite this, the project’s research with stakeholders from those communities has found that they continue to raise the same concerns that have been expressed about the news media since the 1970s. In focus group research, stakeholders from these communities expressed concern about their continuing under-representation or omission from the news media. They felt that voices, experiences, perspectives and issues from their communities rarely appeared, or if they did appear, it was in limited contexts – often in circumstances that portrayed them as vulnerable or disruptive. They also pointed to ongoing media misrepresentation, such as stereotyping, inappropriate framing, and over-reliance on ‘usual suspects’ to talk about their communities. A common theme that they voiced was their need for greater inclusiveness in the media. Participants wished that journalists would better represent the diversity of life experiences and perspectives within their communities. Stakeholders also wanted an increased in representation of their political frameworks, such as stories about the difficulties they encountered in dealing with social and bureaucratic systems, and their understandings of causes and potential solutions for issues affecting their communities.

This paper explores the design of virtual and physical learning spaces developed for students of drama and theatre studies. What can we learn from the traditional drama workshop that will inform the design of drama and theatre spaces created in technology-mediated learning environments? The authors examine four examples of spaces created for online, distance and on-campus students and discuss the relationship between the choice of technology, the learning and teaching methods, and the outcomes for student engagement. Combining insights from two previous action research projects, the discussion focuses on the physical space used for contemporary drama workshops, supplemented by Web 2.0 technologies; a modular online theatre studies course; the blogging space of students creating a group devised play; and the open and immersive world of Second Life, where students explore 3D simulations of historical theatre sites. The authors argue that the drama workshop can be used as inspiration for the design of successful online classrooms. This is achieved by focusing on students’ contributions to the learning as individuals and group members, the aesthetics and mise-en-scene of the learning space, and the role of mobile and networked technologies. Students in this environment increase their capacity to become co-creators of knowledge and to achieve creative outcomes. The drama workshop space in its physical and virtual forms is seen as a model for classrooms in other disciplines, where dynamic, creative and collaborative spaces are required.

In Balnaves v Smith [2012] QSC 408 Byrne SJA concluded that an offer to settle could be an “offer to settle” under Chapter 9 Part 5 of the Uniform Civil Procedure Rules 1999 (Qld) (UCPR) despite the inclusion of non-monetary terms. His Honour took a different approach to that taken by Moynihan SJA in Taske v Occupational & Medical Innovations Ltd [2007] QSC 147.

Purpose: The precise shape of the three-dimensional dose distributions created by intensity-modulated radiotherapy means that the verification of patient position and setup is crucial to the outcome of the treatment. In this paper, we investigate and compare the use of two different image calibration procedures that allow extraction of patient anatomy from measured electronic portal images of intensity-modulated treatment beams. Methods and Materials: Electronic portal images of the intensity-modulated treatment beam delivered using the dynamic multileaf collimator technique were acquired. The images were formed by measuring a series of frames or segments throughout the delivery of the beams. The frames were then summed to produce an integrated portal image of the delivered beam. Two different methods for calibrating the integrated image were investigated with the aim of removing the intensity modulations of the beam. The first involved a simple point-by-point division of the integrated image by a single calibration image of the intensity-modulated beam delivered to a homogeneous polymethyl methacrylate (PMMA) phantom. The second calibration method is known as the quadratic calibration method and required a series of calibration images of the intensity-modulated beam delivered to different thicknesses of homogeneous PMMA blocks. Measurements were made using two different detector systems: a Varian amorphous silicon flat-panel imager and a Theraview camera-based system. The methods were tested first using a contrast phantom before images were acquired of intensity-modulated radiotherapy treatment delivered to the prostate and pelvic nodes of cancer patients at the Royal Marsden Hospital. Results: The results indicate that the calibration methods can be used to remove the intensity modulations of the beam, making it possible to see the outlines of bony anatomy that could be used for patient position verification. This was shown for both posterior and lateral delivered fields. Conclusions: Very little difference between the two calibration methods was observed, so the simpler division method, requiring only the single extra calibration measurement and much simpler computation, was the favored method. This new method could provide a complementary tool to existing position verification methods, and it has the advantage that it is completely passive, requiring no further dose to the patient and using only the treatment fields.

This thesis researched how the anthropological claims of the Aborigines as a 'doomed race' in the decades between 1850 and 1870 became embedded and manifested in pervasive ideologies forming the racist protectionist policies framed in Queensland's Aboriginals Protection and Restriction of the Sale of Opium Act - 1897. Administering the Act was the government appointed Chief Protector of Aboriginals. Conferred with extraordinary powers, Chief Protectors acted and made decisions on behalf of successive governments who displayed little interest in Aboriginal affairs. Amendments to the Act between 1897 and 1939 reflected personal agendas and attitudes towards Aborigines by respective Chief Protectors. Conclusively, the research outcomes show that the 'doomed race' theory became a subterfuge for governments to mask society's racial prejudice against Indigenous peoples and allowed governments to dispossess the Indigenous people of their traditional lands without question from white settlers.

The article focuses on how the information seeker makes decisions about relevance. It will employ a novel decision theory based on quantum probabilities. This direction derives from mounting research within the field of cognitive science showing that decision theory based on quantum probabilities is superior to modelling human judgements than standard probability models [2, 1]. By quantum probabilities, we mean decision event space is modelled as vector space rather than the usual Boolean algebra of sets. In this way,incompatible perspectives around a decision can be modelled leading to an interference term which modifies the law of total probability. The interference term is crucial in modifying the probability judgements made by current probabilistic systems so they align better with human judgement. The goal of this article is thus to model the information seeker user as a decision maker. For this purpose, signal detection models will be sketched which are in principle applicable in a wide variety of information seeking scenarios.

Fruit flies are the insects which cause maggots in your backyard fruit and vegetables. They are not just a nuisance to gardeners, but the single greatest insect threat to commercial and subsistence fruit growers throughout Asia, Australia and the Pacific. Queensland fruit fly, the focus of this PhD, costs Australia an estimated $100million per year. I focused specifically on how Queensland fruit fly uses different commercial citrus varieties. I identified specific plant related mechanisms which increase a fruit’s resistance to fruit fly attack. This information can be used by plant breeders to make fruit less prone to fruit fly damage.

BACKGROUND: A comparison of the management of medicines by the older-aged living in freehold (fully owned) and rental homes in retirement villages has suggested that the older-aged living in rental, but not freehold, retirement villages may require help to manage their medicines. OBJECTIVE: The objective of this study was to investigate the management of medicines by the older-aged living independently in a leasehold (partly owned) home in retirement village to determine whether they also need help in managing their medicines. METHOD: Semi-structured interviews were conducted with 22 older-aged residents living in a leasehold retirement village. MAIN OUTCOME MEASURE: The main outcome measure was the perception of present and ongoing adherence. RESULTS: Amongst participants in the leasehold retirement village, with an average age of 82.9 years, the perceptions of present and ongoing adherence indicated that only 55 % of older-aged participants were adherent at the time of the study, and not likely to have problems with adherence within the next 6-12 months. Participants from the leasehold retirement village had a good understanding of 58 % of their illnesses. A mean of 9.8 medicines per person were prescribed. Cardiovascular medicines were the most commonly prescribed at 86 %. CONCLUSION: The older-aged living in leasehold retirement villages may require extra assistance/resources to manage their medicines.
