A distributed active defense system against DDoS attacks

This thesis proposes a novel architecture of Distributed Active Defense System (DADS) against Distibuted Denial of Service (DDoS) attacks. Three sub-systems of DADS were built. For each sub-system corresponding algorithms were developed, prototypes implemented, criteria for evaluation were set up and experiments in both simulation and real network laboratory environments were carried out.

New criminal sanctions-inflicting pain through the denial of employment and education

Imprisonments and fines are the standard sanctions employed by most western countries in punishing offenders.  Where neither of these penalties is appropriate, the courts normally have a variety of indeterminate sanctions at their disposal.  However the general effectiveness of these sanctions is questionable.  This paper argues that the criminal justice system has been too slow and unimaginative in developing efficient and effective methods of punishing offenders.  There are ways of inflicting pain on offenders that do not encroach on their liberty or affect their material wealth.  It is suggested that new sentencing options should include the annulment or suspension of an offenders academic qualifications and the making of orders preventing an offender from working or being enrolled in an educational or vocational pursuit.

Case comment: Cubillo and Gunner V The Commonwealth: a denial of the stolen generation?

In the recent Australian decision in Cubillo and Gunner v The Commonwealth ( ‘Cubillo 3’ ), the Full Court of the Federal Court dismissed an appeal by the Aboriginal claimants seeking damages for, inter alia, their removal from their families and detention at certain Aboriginal institutions. The removal and detention of the plaintiffs was held to be lawful in the earlier determination of O’Loughlin J because it was, inter alia, believed to be in the [then] child’s best interests and, as the plaintiffs bore the onus of proof, they had failed to show that they were taken without the consent of their parents/guardians. This decision was based upon the factual finding that ‘at the relevant times, there was no general policy in force in the Northern Territory supporting the indiscriminate removal and detention of part-Aboriginal children, irrespective of the personal circumstances of each child’. The Full Court did not comment on O’Loughlin J’s assertion that the policy of removing part-Aboriginal children, as asserted by the plaintiffs, could not be maintained. Moreover, the Full Court in fact joined O’Loughlin J in trying to distance their findings from the broader issue of the legal rights of members of the Stolen Generation, emphasising that they were only concerned with the particular circumstances of the two plaintiffs/appellants. This case comment is not aimed at evaluating the specific legal issues raised by the plaintiffs’ claims in this case or reviewing the history of the Stolen Generation, but rather seeks to examine O’Loughlin J’s comment as to the absence of a policy of indiscriminate removal and detention of part-Aboriginal children in a bid to determine the parameters intended by the court. It will be seen that, at its broadest, the statement is quite inflammatory and may be seen as a denial of the Stolen Generation. It will be submitted that this was not intended by the court. At its narrowest, the statement is merely an assertion that the particular plaintiffs failed to prove their cases. It will be submitted that, whilst this clearly was the view of the court, O’Loughlin J’s statement does have broader implications which, it will be contended, are not warranted.

Service provision factors that affect the health and wellbeing of people living in a lower SES environment: the perspective of service providers

Inequalities in health and wellbeing within low socioeconomic (SES)  environments are well documented. Factors inherent to the health care system itself, such as inaccessible, inflexible or inappropriate seroiceprovision, contribute to the poorer health status ofresidents oflow SES areas. This paper explores the issues ofseroice provision in low SES areas, documenting the perceptions of seroice providers about the seroice needs of residents, in order to understand the systemic factors that negatively impact on health and wellbeing. A total of54 health and welfare seroice providers from two adjacent low SES suburbs within regional Victoria were interoiewed using qualitative research methods. Keyfindings indicate that successful navigation of health care seroices by residents within these low SES environments is being impeded by issues ofaccess, a lack ofappropriate early interoention options or measures, and general resident disempowerment. Central to the improvement of seroice provision is the need for seroices to become economically, geographically and culturally accessible. In particular, the importance of community involvement in health planning and health promoting seroices must be reflected in the ethos ofseroice provision.

The impact of service intangibility on consumer service quality expectations

Research consistently demonstrates the strategic benefits of providing quality in service delivery (Tse and Wilton 1988; Anderson and Zeithaml 1984). However, to deliver a quality service, it is first necessary to determine the level of quality expectations that consumers have for a particular service industry. This paper examines whether quality expectations vary across services based on their degree of total intangibility. A controlled, repeated measures design is utilised, whereby subjects are each asked to evaluate three services that vary in their degree of intangibility. Contrary to past findings, results indicate that consumer expectations for service quality do not vary with the level of intangibility of the service.

Service failure and recovery in the presence of service guarantees

This paper presents a conceptual model and propositions outlining how, in a service recovery encounter, service guarantees (unconditional and specific) operate in conjunction with other organisational recovery variables (guarantee facilitation and service provider concern), to influence customers’ justice perceptions and subsequent satisfaction evaluations.

There's a fly in my soup : the influence of service guarantees and personal requests on customer voice

Anecdotal evidence suggests that service guarantees and personal requests by service workers encourage customers to voice following failure. However, empirical support for these tactics in facilitating complaints to the organisation is limited. To address this deficiency, a 3 (guarantee treatment: none, unconditional or combined) x 2 (personal request to voice: yes or no) x 2 (failure severity: minor or major) full factorial, between subjects experiment was conducted in a restaurant context. Findings suggest that offering a service guarantee, regardless of whether it is unconditional or combined, can encourage voice. Severity of the failure was also found to be associated with voice. Surprisingly, however, a personal request to voice was not related to customers’ voice intentions. Implications of the findings are discussed.

Ebia Olewale : a life of service

Over the last seven decades, Papua New Guinea (PNG) has grown from a disparate collection of traditional societies loosely governed by its neighbour, Australia, to a thriving, developing state. The story of how PNG came to lose its colonial shackles and gain independence is one of collective endeavour, as the tiny group of Papua New Guineans who gathered in the dusty streets of Port Moresby transformed into the leaders of the new nation. One of them was the young teacher, Ebia Olewale, who in his own journey from the village to the nation experienced many triumphs and tragedies. PNG’s story – from the village to the world – is retold in this book, through the experiences of Ebia Olewale.

Relationships, the role of individuals and knowledge flows in the internationalization of service firms

This article develops a new conceptual model of knowledge flows within international service firms. Our model takes explicit account of the critical role of relationships and the individual as being central to the process of knowledge transfer for service firms. The model is then validated with data collected from five international service firms using critical event analysis techniques. The findings reinforce our contention that the individual plays a critical role in the process of knowledge transfer and that relationships form an integral part of this process. The implications of this finding are also discussed.
