Distributed defense is a promising way to neutralize the distributed Denial-of-Service attacks by detecting and responding the attacking sources widespread around the Internet. Components of the distributed defense system will cooperate with each other to combat the attacks. Compared with the centralized defense systems, distributed defense systems can discover the attacks more timely from both source end and victim end, fight the attacks with more resources and take advantage of more flexible strategies. This paper investigates 7 distributed defense systems which make use of various strategies to mitigate the DDoS attacks. Different architectures are designed in these 7 systems to provide distributed DDoS defense solutions. We evaluate these systems in terms of deployment, detection, response, security, robustness and implementation. For each criteria, we give a recommendation on which technologies are best suitable for a successful distributed defense system based on the analysis result. Finally we propose our idea on the design of an effective distributed defense system.

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.

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.

Quality-of-Service is an important issue in multimedia applications; so far most of the research focuses on bandwidth guarantee, few pays attention to the server performance guarantee. In this paper we pay more attention to the server performance guarantee under the prerequisite of guaranteed bandwidth quality. We take advantage of anycast to find the "best" multimedia server among a distributed server group in terms of bandwidth, the request will be submitted to the selected server, moreover, the selected server's neighbours' (all the servers with feasible paths) addresses are delivered to the selected server simultaneously. If the selected server can not guarantee the QoS for the request in terms of server performance, then a proposed QoS-Aware Server Load Deviation (QASLD) mechanism wiII be employed, which will deliver the request to one of its neighbours until there exists a suitable server that can guarantee the server performance for the request. Our experiments show that the proposed QASLD algorithm works well.

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 are two statistical decision making questions regarding statistically detecting sings of denial-of-service flooding attacks. One is how to represent the distributions of detection probability, false alarm probability and miss probability. The other is how to quantitatively express a decision region within which one may make a decision that has high detection probability, low false alarm probability and low miss probability. This paper gives the answers to the above questions. In addition, a case study is demonstrated.

Abstract The purpose of this study was to identify place-specific dimensions of service quality in spectator sport settings and determine if the importance of these dimensions differed across cultures. The study was limited to the soccer industry and involved the collection of responses from identified soccer spectators to a range of items presented in a survey instrument. The survey was distributed to respondents face-to-face on a match day of the club they supported, or mailed to their home address. Responses were obtained from spectators from two clubs from Australia (n=277), one club from the USA (n=199), one club from the Netherlands (n=245) and one federation from Malaysia (n= 100). Based on the findings of a number of authors, six categories of potential place-specific dimensions of service quality in spectator sport settings were created and the research instrument contained a number of items that could be categorised under one of these headings. These categories were Home, Religion, Social facilitation, Sensory, Uncertainty of outcome, and Personal attention. In this thesis it was assumed that place-specific service quality issues are similar for sport spectators of different cultures, although differences in degree of importance of these dimensions (etic approach) were likely to emerge. In other words, although it was expected dimensions per country to be similar, differences in degree of importance of these dimensions were expected. Given the lack of confirmatory statistical evidence pertaining to the specific country samples, it was concluded that differences per country are likely to be more than just differences in degree. Both the overall structure and structures per country could not be confirmed, and hence the conclusion was drawn that differences in nature between the countries were present. In other words, what is a dimension of place-specific service quality in one country is not necessarily a dimension in another country. The results of a content analysis of ‘core component’ structures per country compared with a (full sample) core component structure delivered six components (referred to as place-specific dimensions of service quality) that were defined as Home, Hedonist, Religious follower, Safe atmosphere, Hospitality and Personal Attention. It was found that in most cases the cultural orientation of soccer spectators reflects the cultural orientation of the country as a whole as proposed by Hofstede (1991). However, in line with Huntington (1997), it was also argued that grouping people based on their country of origin as a proxy for their cultural orientation, will increasingly lead to flawed and incomplete research findings. As noted by Yoo etal. (1999), the identification of a person's cultural orientation is likely to deliver more direct results when measured at the individual level In that regard it is concluded that it may seem prudent to view Hofstede's dimensions of culture with increased conceptual scrutiny. Although having been replicated in multiple studies, it becomes increasingly unlikely that Hofstede's dimensions cover the complete spectrum of an individual person's cultural orientation. In conclusion, this study identified that soccer spectators (from a number of clubs) from Australia, the USA, the Netherlands and to a lesser extent Malaysia, perceive a range of place-specific service quality dimensions in spectator spoil settings to be important when visiting a soccer match. Before research into satisfaction with and value of place-specific dimensions of the spectator sport service product is initiated, it is pertinent the identified dimensions are further explored and confirmed in different country (culture) settings. The confusion that still exists about the place of the value concept (in relation to quality and satisfaction), where Holbrook (1994) defines quality as a type of value and Chelladurai and Chang (2000) argue that value is a type of quality, further underpins this necessity. It needs to be clear what are the targets of service quality before this information is integrated in larger holistic research frameworks. In the final section of the thesis a conceptual model for international services marketing research in the sport industry was presented as a first attempt to integrate the findings of this research and other researchers.

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.
