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.

Libraries are dynamic organization providing dynamic services to their patrons. However, advances in IT and networking have created a serious competition to libraries from many information service provisioning agents. The purpose of this study is to understand the issue relevant to service quality assessment in libraries and subsequently develop a conceptual model of aligning library quality of service assessment for effective reporting of library value and performance to stakeholders. In this paper, we will focus on the provision of library services and the nature of the relationship and interactions between various components of library services.

It is paramount to provide seamless and ubiquitous access to rich contents available online to interested users via a wide range of devices with varied characteristics. Recently, a service-oriented content adaptation scheme has emerged to address this content-device mismatch problem. In this scheme, content adaptation functions are provided as services by third-party providers. Clients pay for the consumed services and thus demand service quality. As such, negotiating for the QoS offers, assuring negotiated QoS levels and accuracy of adapted content version are essential. Any non-compliance should be handled and reported in real time. These issues elevate the management of service level agreement (SLA) as an important problem. This chapter presents prior work, important challenges, and a framework for managing SLA for service-oriented content adaptation platform.

Purpose – The purpose of the paper is to report on the perception of students in regard to critical antecedents, dimensions and consequences of service quality with an aim to develop a theoretical model in the context of a university in Australia.

Design/methodology/approach –
This research used focus group discussions with 19 students who had been studying in undergraduate and postgraduate level programs at an Australian university.

Findings – The findings show that the critical antecedents to perceived service quality are information and past experience. There are three aspects of perceived service quality, namely, academic, administrative and facilities. Student satisfaction and student trust are found to have direct and positive relationships with perceived service quality as consequences; and brand performance and behavioural intention are found to have indirect relationships with perceived service quality mediated through satisfaction and trust.

Originality/value –
This paper found three separate themes and their relationships with service quality in the context of a university. These themes are: information, past experience and brand performance. Perceived service quality was found playing an important role in this theoretical model. The model provides a good explanation of university brand performance and students' behavioural intentions.

The evolution of domestic air travel service in Japan is a product of many factors including airline responses to the changing aviation market, government interventions in terms of regulatory/deregulatory policies, infrastructure investments, and changes in market structure. This paper presents an empirical investigation of the changing quality of passenger airline service and its implications in the domestic aviation market in Japan using qualitative review and a time series analysis of the domestic airline markets from 1986 to 2003. The results show that to meet the ultimate aim of deregulation to increase air passengers’ welfare gain, there is a need to instill measures to correct service imbalance and to create innovative airport demand-capacity management measures.

Introduction: A workplace orientation program is a core requirement of the National Safety and Quality Health Service (NSQHS) Standards in Australia. This is particularly important within healthcare as patient safety and the patient experience are at risk if the healthcare workforce is not supported with an effective orientation and induction program. Aim: This study aimed to review the literature and map the requirements of the NSQHS Standards in relation to orientation and induction. Method: This study utilised online databases to search for literature pertaining to orientation and induction within healthcare. Inclusion criteria included relevance to research questions, and originating in a country with a comparative health system to Australia. Results: The search identified a total of 202 articles of potential relevance with 42 articles meeting the inclusion criteria. Articles were ranked according to hierarchy of evidence criteria for both qualitative and quantitative studies. The importance of using orientation to detail safety and quality roles, the organisations' risk management system, governance structure, operational processes and procedures was highlighted. Patient-centred care, antimicrobial stewardship, clinical handover and mechanisms for escalation of care and emergency assistance should also be covered within the orientation process. Conclusion: There is a dearth of studies in relation to orientation and induction in the healthcare literature. Orientation content is now clearly prescribed, what is lacking within healthcare is a standardised framework. Concept mapping, educational theory and adult learning methods have been shown to enhance workforce problem solving and engagement with orientation, however further research is needed to enhance practice

Word-of-mouth is a powerful force in today’s marketplace. However, few researchers
examine how the dimensions of SERVQUAL relate to positive word-of-mouth, particularly in
the Chinese market. This study attempts to fill this gap. The context is Chinese
telecommunication market. A survey was conducted with a sample of 241 respondents. The
results showed that Reliability and Assurance encouraged more positive word-of-mouth
intention, while Tangibles, Responsiveness, and Empathy did not have any significant effect
on one’s word-of-mouth. These findings have useful implications to international service
companies, particularly those operating in a Chinese environment, by identifying factors that
are salient to the generation of positive word-of-mouth.

Brazil is under political and financial crises where the end seems far away. Because of that, researchers argue that the hotel rooms offered by Rio de Janeiro, built to host the Olympic Games 2016, will be difficult to occupy after the event. It is then necessary for the hotels to understand how guests perceive the service quality in order to adapt to this new era. If guests’ perceptions meet or exceed their expectations, they will be satisfied and will probably return. Thus based on the SERVQUAL approach, this paper aims to study the impact of the service dimensions on the guests’ overall satisfaction at hotels of Rio de Janeiro. Two hotels were considered representative of the city in terms of service quality and customers’ profile. Interviews to the hotel managers were performed, and questionnaires to the guests were administered. Among the five SERVQUAL dimensions – Reliability, Tangibles, Responsiveness, Assurance, and Empathy – the Empathy dimension appears to be the only one that affects the guests’ overall satisfaction. The study could also identify that gender, country of residence, home country and family income have an impact on guests’ satisfaction. This study has no intention of generalization, but rather of refining the theory about services and the SERVQUAL model.

Service provisioning is a challenging research area for the design and implementation of autonomic service-oriented software systems. It includes automated QoS management for such systems and their applications. Monitoring, Diagnosis and Repair are three key features of QoS management. This work presents a self-healing Web service-based framework that manages QoS degradation at runtime. Our approach is based on proxies. Proxies act on meta-level communications and extend the HTTP envelope of the exchanged messages with QoS-related parameter values. QoS Data are filtered over time and analysed using statistical functions and the Hidden Markov Model. Detected QoS degradations are handled with proxies. We experienced our framework using an orchestrated electronic shop application (FoodShop).

The aim of this study is to establish the factors that influence the quality of life of people living with HIV/AIDS being treated at a specialized public service. The participants answered the questionnaire on sociodemographic conditions, issues related to HIV and daily habits. The quality of life was analyzed using the HIV/AIDS-targeted quality of life (HAT-QoL) instrument with 42 items divided into 9 fields: General Activity, Sexual Activity, Confidentiality Concerns, Health Concerns, Financial Concerns, HIV Awareness, Satisfaction with Life, Issues related to Medication and Trust in the Physician. Bivariate and multiple linear regressions were performed. Of the participants, 53.1% were women and had a mean age of 42 years. In analyzing the quality of life, the HAT-QoL domain with the lowest average was Financial Concerns (39.4), followed by Confidentiality Concerns (43.2), Sexual Activity (55.2) and Health Concerns (62. 88). There was an association between the variables: not being gainfully employed (p < 0.001), being mulatto or black (p = 0.045) and alcohol consumption (p = 0.041) with the worst quality of life scores. Inadequate socioeconomic and health conditions had a negative impact on the quality of life of people with HIV/AIDS.

The usage of HTTP adaptive streaming (HAS) has become widely spread in multimedia services. Because it allows the service providers to improve the network resource utilization and user׳s Quality of Experience (QoE). Using this technology, the video playback interruption is reduced since the network and server status in addition to capability of user device, all are taken into account by HAS client to adapt the quality to the current condition. Adaptation can be done using different strategies. In order to provide optimal QoE, the perceptual impact of adaptation strategies from point of view of the user should be studied. However, the time-varying video quality due to the adaptation which usually takes place in a long interval introduces a new type of impairment making the subjective evaluation of adaptive streaming system challenging. The contribution of this paper is two-fold: first, it investigates the testing methodology to evaluate HAS QoE by comparing the subjective experimental outcomes obtained from ACR standardized method and a semi-continuous method developed to evaluate the long sequences. In addition, influence of using audiovisual stimuli to evaluate the video-related impairment is inquired. Second, impact of some of the adaptation technical factors including the quality switching amplitude and chunk size in combination with high range of commercial content type is investigated. The results of this study provide a good insight toward achieving appropriate testing method to evaluate HAS QoE, in addition to designing switching strategies with optimal visual quality.
