IT security certifications : stakeholder evaluation and selection

Information technology (IT) security certifications have proliferated in recent years. However they differ in regards to stakeholder considerations of credibility, accessibility and relevance. Key stakeholders with an interest in selecting an IT security certification (IT security professionals, employers, governments and higher education institutes) lack a systematic approach for differentiating between candidate certifications and selecting the “best” certification to satisfy requirements. The paper focuses on reporting a confirmatory focus group from a recent research project. It provides a framework for supporting stakeholder evaluation and selection of IT security certifications and discusses key implications for the IT security industry, IT security certifications, and the higher education sector.

Cytochemical characterisation of the leucocytes and thrombocytes from murray cod (Maccullochella peelii peelii, Mitchell)

Cytochemistry has proven effective in differentiating specific cell lineages and elucidating their functional properties. This study utilised a range of cytochemical techniques to further investigate the leucocyte populations from Murray cod, an iconic Australian teleost fish species. This analysis provided clear insight into the structure and function of the leucocytes from this fish, which were found to be broadly similar to those of other fish species. However, some important differences were identified in Murray cod, such as the presence of naphthol AS chloroacetate esterase activity in the heterophil population, positive staining for periodic acid Schiff's, alkaline phosphatase and Sudan black B in the lymphocyte population, and a prevalent population of myeloid precursor cells.

Developing student transferable skills through reflective porfolios

The development of transferable skills in students, ie those relevant to any future employment, is a common goal of degree programmes. Reflection is a mechanism frequently used in the training of medical and teaching professionals to develop self-awareness of personal skills levels that enable participants to become self-reflective practitioners. The intention in this research was to trial reflection for construction management and architecture students through a series of interventions to engage students in the explicit development of transferable skills and self-awareness. Students were required to keep a ‘diary’ or journal under specific skills headings: communication (involving active listening, conflict resolution, negotiation), team building, problem solving, report writing and presentation skills based on their experiences at university, work and in social situations. A range of learning resources were made available to assist students. The journals were analysed according to a recognised coding for the depth of their reflection . At the end of the semester, students were required to “apply” for a job description that required explication of the knowledge and skills that were intended to be further developed during the unit. In practice, few students appreciated the journaling and some were even hostile to the process, but all students demonstrated good appreciation of their abilities and skills in the job application – essentially a mechanism that required reflection. In conclusion, explicit reflection through journaling is not a universally popular practice, but tasks that appear to have some foundation in practicality that require reflection are more likely to be appreciated. Students depth of reflection was found to improve through practice.

Is neoliberalism a Liberalism, or a strange kind of bird? On Hayek and our discontents

This paper examines the theoretical ideas of Friedrich von Hayek, arguably the key progenitor of the global economic orthodoxy of the past two decades. It assesses Hayek's thought as he presents it: namely as a form of liberalism. Section I argues that Hayek's thought, if liberal, is hostile to participatory democracy. Section II then argues the more radical thesis that neoliberalism is also in truth an illiberal doctrine. Founded not in any social contract doctrine, but a form of constructivism, neoliberal thought at its base accepts the paradoxical need to "discipline subjects for freedom", however this might contravene peoples' natural, social inclinations. The argument is framed by reference to Aristophanes' great comedy, The Birds, whose off shore borderless empire ironically prefigures the dream of neoliberal social engineers, and their corporate supporters.

The development of a typology for remote construction projects

Remotely located sites have become more accessible and therefore more valuable and profitable to investors and entrepreneurs. Typically these sites are environmentally sensitive. For the designer, these sites offer a unique challenge conceptually, in terms of the physical and cultural constraints. The built environment research community has yet to seriously take up the challenge of developing theoretical models for the management of the design and construction processes for remotely located projects. Such models would explore efficiency and efficacy management for projects in remote and often hostile areas, in an integrated and sustainable manner. There are varying degrees of remoteness experienced in nearly all construction projects and therefore a clearer definition of the characteristics of remote sites is required. Towards this definition, a typology is initiated for the concept of remotely located construction projects related to environmental sustainability and the management of the design process. The characteristics of the typology are drawn from a selected literature review of the fields of design management and environmental sustainability, and from an exploratory investigation of two case studies.

An examination of taxpayers' attitutes towards the Australian Tax System : findings from a survey of tax scheme investors

In recent years, the number of taxpayers involved in aggressive tax planning has more than doubled, posing a serious threat to the integrity of Australia's tax system. To deal with the problem, the Australian Taxation Office (ATO) implemented a number of initiatives aimed at combating aggressive tax planning. Part of the ATO's crackdown involved issuing amended assessments to the 42,000 Australians who invested in mass marketed tax schemes. The majority of investors, however, resisted the ATO's attempts to recover scheme related tax debts. This paper discusses the findings of an empirical study that shows that the resistance was due partly to the manner in which the ATO dealt with the schemes issue. Using survey data collected from 2301 tax scheme investors, and 2040 taxpayers from the general population, it will be shown that those who invested in tax schemes are more disillusioned with the tax system, are more hostile and resistant toward the ATO, and are more likely to resent paying tax as a result.

Virulence determinants of infectious bursal disease virus

The very virulent (vv) pathotype of infectious bursal disease virus (IBDV) has spread rapidly throughout Europe, Asia, and the Middle East. Although Australia is currently unaffected, there remains the potential for incursion of an exotic isolate. The aim of this study was to identify putative virulence determinants of IBDV to facilitate the development of improved diagnostic assays for detection and characterisation of vvIBDV isolates. Sequencing of Indonesian vvIBDV Tasik94 revealed a unique substitution [ A�¨S222] in the hypervariable region (HVR) of viral protein (VP) VP2, which did not appear to impinge on virulence or antigenicity. Phylogenetic analyses indicated that Tasik94 was closely related to Asian and European vvIBDV strains. Extensive alignment of deduced protein sequences across the HVR of VP2 identified residuesI242 I256 and I294 as putative markers of the vv phcnotype. Comparison of the pathology induced by mildly-virulent Australian IBDV 002/73 and Indonesian vvIBDV Tasik94, revealed that histological lesions in the spleen, thymus and bone marrow were restricted to Tasik94-infected birds, suggesting the enhanced pathogenicity of vvIBDV might be attributed to replication in non-bursal lymphoid organs. The biological significance of the VP2 HVR in virulence was assessed using recombinant viruses generated by reverse genetics. Both genomic segments of Australian IBDV 002/73, and recombinant segment A constructs in which the HVR of 002/73 was replaced with the corresponding region of either tissue culture-adapted virus or vvIBDV (Tasik94), were cloned behind T7 RNA polymerase promoter sequences. In vitro transcription/translation of each construct resulted in expression of viral proteins. Co-transfection of synthetic RNA transcripts initiated replication of both tissue culture-adapted parental and recombinant viruses, however attempts to rescue non-adapted viruses in specific-pathogen-free (SPF) chickens were unsuccessful. Nucleotide sequence variation in the HVR of VP2 was exploited for the development of a new diagnostic assay to rapidly detect exotic IBDV isolates, including vvIBDV, using reverse transcription polymerase chain reaction (RT-PCR) amplification and Bmrl restriction enzyme digestion. The assay was capable of differentiating between endemic and exotic IBDV in 96% of 105 isolates sequenced to date.

Identifying and developing executive skills

This study aimed to identify those skills which, individually or in combination, contribute to a high standard of management practice by Chief Executive Officers in Australia. Based on an extensive review of the literature, a skill taxonomy was developed to reflect current research findings. Verification of this taxonomy was sought through field questionnaires and depth interviews with male and female CEOs drawn from large and small organisations in both the public and private sectors. This led to a revised skill taxonomy, with 17 skills reflecting three significant categories; understanding and interpreting the external environment understanding and mobilising the internal environment and understanding and mobilising personal resources’ Eight of the skills were identified as key differentiating skills. They are situational, contingent and interdependent They reflect the broad context in which they are applied and their interrelationships in the wider environment. The research then sought to determine how these skills were acquired or developed. The motivation and capacity for continual learning was a key factor. The most effective learning took place in a randomised, unstructured, incremental and integrative fashion. Experiences associated with breadth, diversity, challenge and with reassessing perspectives and personal paradigms were of particular significance. It was found that an ordered, structured and purposive learning approach — as implied by most existing learning models — does not necessarily enhance the acquisition of the key skills; it may well impede their development. This led to the theoretical conclusion that there are three modes of learning relevant to senior executives; instrumental learning (‘learning to do’), systemic learning (‘learning to be’) and meta-learning (‘learning to learn’). The implications are drawn out, with particular reference to the experiences and facilitative organisational environments needed for the development of systemic and meta-learning; the modes considered of most importance if senior executives are to be able to effectively respond to the organisational and environmental challenges they face.

Beyond Abrahamism : a fresh reading of the Tanakh traditions respecting Lot, Moab and Ammon

At the heart of this study is my interest in the way in which a religious community establishes its sense of identity and its boundaries in relation to other groups. I explore the case of Israel's attitude towards her eastern neighbours, the Moabites and Ammonites, as portrayed in Tanakh, the Hebrew Bible. Most commentary from the last one hundred years privileges one particular view of Moab and Ammon as traditional enemies of Israel. I aim to show the validity of readings of the biblical accounts that reveal a more complex relationship between Israel and her neighbours. Tanakh exhibits a dialectic between eirenic and hostile viewpoints. The stories of Abraham and Lot, who are presented as ancestors of Israel and of Moab and Ammon, to some degree represent Israel’s understanding of her neighbours. Conventional commentaries take for granted the accepted orthodoxy of Judaism, Christianity and Islam concerning Abraham and his significance in terms of faith and righteousness and blessing and covenant. As none of these notions is specifically linked to Lot at any point, he is treated as a pathetic figure and remains secondary in conventional commentary. Many commentaries denigrate the character of Lot, often in direct comparisons with Abraham. My reading of the texts of Genesis attempts to free the story of Lot from the constraints imposed by the way the story of Abraham functions. A careful reading of the Genesis account shows that Lot and Abraham exhibit similar elements of moral ambiguity, and Genesis contains no statement that condemns Lot on moral or religious grounds. Genesis 19, the single narrative in which Lot appears independently of Abraham, participates in the dialectic elsewhere in Tanakh. On the basis of a consistent pattern of action and speech throughout the first portion of Genesis 19, I advance my own original conception of the eirenic viewpoint of the narrator concerning Lot and his relationship to the divine. I attempt to demonstrate ways in which the story of Lot critiques or deconstructs the dominant ideology centred upon Abraham. My conception of the particular interests of the compiler of Genesis 19 is supported by several intertextual studies. These include the traditions of Sodom and of Zoar, the story of hospitality in Judges 19, the story of the deluge (Genesis 6-9) and stories of women who, like Lot’s daughters, act to continue the family line. In a treatment of the history of Lot traditions, I find evidence to separate the story of Lot from the work of the Yahwist. I consider whether the stories of Lot have a derivation east of the Jordan and whether the stories were of particular interest to the Deuteronomists. In the final chapter of this study, I focus on the main themes of the narratives concerning Lot and Abraham, and Moab and Ammon and Israel. The question of social boundaries arises in regard to many of these themes, such as the interaction of female and male, the role of wealth, the relation of city and country, kinship, and rights to land settlement. In this way, the treatment of Lot and Abraham in Tanakh and in subsequent traditions offers a perspective upon the formation of identity in the contemporary world of religious plurality.

Foucauldian analysis and 'the best interests of the child'

In this thesis I have developed a theoretical framework using Michel Foucault’s metaphor of the panopticon and applied the resulting discursive methodology to prominent risk assessment texts in Tasmanian Government child protection services. From the analysis I have developed an innovation poststructural practice of discursive empathy for use in child protection social work. Previous research has examined discourses such as madness, mothering, the family and masculinity using Foucault’s ideas and argued that each is a performance of social government. However my interest is in ‘the best interests of the child’ as governmentality; risk as the apparatus through which it is conducted and child abuse its social effect. In applying a discursive analysis, practices of risk assessment are therefore understood to actually produce intellectual and material conditions favourable to child abuse, rather than protect children from maltreatment. The theoretical framework produces in this thesis incorporates three distinct components of Foucault’s interpretive analytics of power: archaeology, genealogy and ethics. These components provide a structure for discourse analysis that is also a coherent methodical practice of Foucault’s notion of ‘parrhesia’. The practice of parrhesia involves social workers recognised that social power is subjectively dispersed yet also hierarchical. Using this notion I have analysed ‘the best interest of the child’ as a panopticon and argued that child abuse is a consequence. This thesis therefore demonstrates how child protection social workers can expose the political purpose involved in the discourse ‘the best interests of the child’, and in doing so challenge the hostile intellectual and material conditions that exist for children in our community. In concluding, I identify how discursive empathy is a readily accessible skill that social workers can use to practice parrhesia in a creative way.

Fast recovery from node compromise in wireless sensor networks

Wireless Sensor Networks (WSNs) are susceptible to a wide range of security attacks in hostile environments due to the limited processing and energy capabilities of sensor nodes. Consequently, the use of WSNs in mission critical applications requires reliable detection and fast recovery from these attacks. While much research has been devoted to detecting security attacks, very little attention has been paid yet to the recovery task. In this paper, we present a novel mechanism that is based on dynamic network reclustering and node reprogramming for recovering from node compromise. In response to node compromise, the proposed recovery approach reclusters the network excluding compromised nodes; thus allowing normal network operation while initiating node recovery procedures. We propose a novel reclustering algorithm that uses 2-hop neighbourhood information for this purpose. For node reprogramming we propose the modified Deluge protocol. The proposed node recovery mechanism is both decentralized and scalable. Moreover, we demonstrate through its implementation on a TelosB-based sensor network testbed that the proposed recovery method performs well in a low-resource WSN.

Ozbot and haptics : remote surveillance to physical presence

This paper reports on robotic and haptic technologies and capabilities developed for the law enforcement and defence community within Australia by the Centre for Intelligent Systems Research (CISR). The OzBot series of small and medium surveillance robots have been designed in Australia and evaluated by law enforcement and defence personnel to determine suitability and ruggedness in a variety of environments. Using custom developed digital electronics and featuring expandable data busses including RS485, I2C, RS232, video and Ethernet, the robots can be directly connected to many off the shelf payloads such as gas sensors, x-ray sources and camera systems including thermal and night vision. Differentiating the OzBot platform from its peers is its ability to be integrated directly with haptic technology or the 'haptic bubble' developed by CISR. Haptic interfaces allow an operator to physically 'feel' remote environments through position-force control and experience realistic force feedback. By adding the capability to remotely grasp an object, feel its weight, texture and other physical properties in real-time from the remote ground control unit, an operator's situational awareness is greatly improved through Haptic augmentation in an environment where remote-system feedback is often limited.

63Cu NMR investigation of effect of small additions of Sn to Al-1.7 at.%Cu in promoting accelerated phase transformations on aging

Very recently 63Cu NMR has been shown to be extremely sensitive in detecting and differentiating between the precipitate phases that form in Al-Cu alloys during heat treatment. This technique is now used to quantify the effectiveness of small additions of Sn to the alloy Al-1.7 at.% Cu in promoting the rapid nucleation and growth of the θ'-phase precipitate. Two parallel series of 63Cu NMR spectra were recorded for Al-1.7 at.% Cu and Al-1.7 at.% Cu-0.01 at.% Sn: (i) aged at 130° C to observe the comparative rate of phase evolution and (ii) aged at 200° C to observe the rate of growth of θ'-phase and to compare with the Vickers hardness of the alloys aged at 200° C for similar periods. Evidence is presented that a metastable precursor phase to θ' (labelled TPHM2757math001) is formed in Al-Cu-Sn which transforms to θ' on further aging.

On the role of cyclic unsaturated additives on the behaviour of lithium metal electrodes in ionic liquid electrolytes

Three cyclic vinyl based additives, based respectively on oxygen, sulphur and fluorine, are tested for their ability to improve the cycling of lithium in a hostile ionic liquid medium. Oxygen based vinylene carbonate is found to offer the best protection of the lithium metal whilst allowing very consistent lithium cycling to occur. The vinylene carbonate based system under study is, however, imperfect. Lithium metal is deposited in a dendritic morphology, and vinylene carbonate is rapidly consumed during lithium cycling if it is present in a small quantity. Our results suggest that ionic liquid systems critically relying on a small amount of additive to protect a lithium electrode are not viable for long cycle life secondary batteries. It is suggested that an ionic liquid which itself is lithium metal compatible be used instead.

The identification of sexual and violent motivations in men who assault women : implication for treatment

A qualitative analysis of interview data with 41 rapists determined that five implicit theories (ITs) underlie rapists’ offense supportive beliefs/feelings/motives: (a) dangerous world (DW)—where men have feelings of generalized anger and/or resentment toward others; (b) women are dangerous—where men hold a set of attitudes that are hostile toward women; (c) women as sexual objects (WSO)—where women are seen as primarily sexual objects; (d) male sex drive is uncontrollable—where sexual urges are seen all consuming; (e) entitlement—where men feel that they can do exactly what they want. Consideration of whether DW or WSO ITs were present or absent indicated that three main groups could be identified: Group 1: violently motivated—presence of DW and/or absence of WSO; Group 2: sexually motivated—presence of WSO and/or absence of DW; Group 3: sadistically motivated—presence of DW and WSO. These results are discussed in terms of treatment needs of rapists.
