This project aimed to conceptualise and analyse empirically the antecedents of word-of-mouth in the context of an infrequently purchased service (tourism special events). The relationships examined included those between involvement, past experience, overall satisfaction, interest in attending next time, likelihood of attending next time, and the likelihood of recommending to others that they attend the event. There was some support for the overall model, in that the regressing of likelihood of recommending on the other variables produced an equation containing measures of most of the key variables, viz., revisit intention, satisfaction, revisit interest, and involvement. However, involvement appeared to operate in the opposite direction to that hypothesised.

The aims of this research were to examine the relationships between customer satisfaction, customer complaint behaviour, service recovery and the intention to repurchase in the Australian Pay TV industry. A survey of 171 respondents suggested that overall customer satisfaction was the main driver of the likelihood of disconnection from the Pay TV service. Those respondents who reported having a problem but not complaining directly about it were significantly more likely to have the intention to disconnect in the future than those who complained directly to their Pay TV service provider. However, there was no significant difference in terms of perceptions of overall satisfaction between those who had a problem and complained and those who had a problem and chose not to complain.

This paper reports on a survey of lapsed members of an Australian professional National Rugby League (NRL) Club. Analysis of the 195 useable responses returned suggest that these lapsed members had originally joined as much for intangible aspects, such as seeking a greater level of involvement with the club, as for the functional aspects such as savings on game entry. Overall, these lapsed members were satisfied with the service they received whilst a member, and claimed it had been performed in line with expectations. The main drivers of satisfaction were also a mix of tangible and intangible factors such as feeling valued by the club and receiving discounts on entry costs. The members gave a number of reasons for not rejoining in 2002, but primarily cited an inability to attend games. Despite joining for intangible reasons, it seems that if these members could not get to games, they perceived that membership was not worth maintaining. That said, a large number of members indicated that as their circumstances change they will rejoin the club, supporting the theory that non-renewal is not driven by service failure, but rather the perception that attendance is still the core product (entertainment). The overall level of satisfaction had a weak but positive relationship with the likelihood of members rejoining in the future.

The role of marketing employees in contributing to marketing performance (individual and organisational), has, in general, been under-researched. Most research in marketing has focused on the activities of marketing employees and the outputs of those activities, rather than the inputs, i.e., the abilities, skills, or knowledge of the marketing employees themselves. This study represents a unique insight into the marketing capabilities and marketing performance of employees within a multinational organisation, as reported by the employees themselves. Using Structural Equation Modelling (SEM), strong support was found for a systems model of marketing competency marketing performance, suggesting that such relationships are complex and are not studied readily in isolation from external factors. Organisations that are able to conceptualise, operationalise, measure, monitor, and address marketing employee competency, intentions, and perceptions, as well as maintain the appropriate levels of management control, should have a greater likelihood of creating high performing employees, than those organisations that are unable to focus on these core aspects of people's performance. In addition, those same employees are likely to be more satisfied, motivated, and committed, require less assistance and time to complete tasks, and have greater productivity and be less likely to leave the orga.'1isation.

There is considerable evidence to suggest that consumer dissatisfaction with self-service technologies is widespread. However, there has been little conceptual or empirical scrutiny of the likelihood that consumers will complain to an organization (likelihood of voice) in this context. This study contributes to the service domain by testing empirically a model of the antecedents of consumers' likelihood of voice in unsatisfactory encounters with self-service technologies. A model is tested that combines established antecedents of voice, such as likelihood of voice success, and those that have not yet been considered, including self-service technology powerlessness and need to vent. The results support the proposed model in general. Theoretical and managerial implications of the findings are discussed.

This paper develops and tests a model to predict small and medium enterprise (SME) financial distress based on empirical evidence from Thailand. A sample comprising 198 financial statements of non-financially distressed and 68 statements of financially distressed SMEs were used. A parametric t-test was conducted to establish differences between financial characteristics of the two groups of SMEs.

Results show statistically significant differences (t values significant at .001) between the two groups of SMEs in the financial ratios used for the study. Discriminant analysis was then conducted to develop a model for predicting the likelihood of an SME experiencing financial distress.

The model hits an accuracy level of 97%, which compares favourably with the probability of accurate classification by chance (i.e., 65% after adjusting for the unequal sample sizes of the two groups of SMEs). A test of the model with a new sample shows the validity of the model beyond the original sample, confirming that Thai SME financial distress is amenable to prediction to a statistically significant extent. The model is expected to serve SME managers and creditors in assessing financial health of SMEs before making important decisions. The results are also expected to inform policymakers in formulating economic policies concerning SMEs.

In 3 studies we recorded gay men's estimates of the likelihood that HIV would be transmitted in various sexual behaviours. In Study 1 (data collected 1993, n=92), the men were found to believe that transmissibility is very much greater than it actually is; that insertive unprotected anal intercourse (UAI) by an HIV-infected partner is made safer by withdrawal before ejaculation, and very much safer by withdrawal before either ejaculation or pre-ejaculation; that UAI is very much safer when an infected partner is receptive rather than insertive; that insertive oral sex by an infected partner is much less risky than even the safest variant of UAI; that HIV is less transmissible very early after infection than later on; and that risk accumulates over repeated acts of UAI less than it actually does. In Study 2 (data collected 1997/8, n=200), it was found that younger and older uninfected men generally gave similar estimates of transmissibility, but that infected men gave somewhat lower estimates than uninfected men; and that estimates were unaffected by asking the men to imagine that they themselves, rather than a hypothetical other gay man, were engaging in the behaviours. Comparison of the 1993 and 1997/8 results suggested that there had been some effect of an educational campaign warning of the dangers of withdrawal; however, there had been no effect either of a campaign warning of the dangers of receptive UAI by an infected partner, or of publicity given to the greater transmissibility of HIV shortly after infection. In Study 3 (data collected 1999, n=59), men induced into a positive mood were found to give lower estimates of transmissibility than either men induced into a neutral mood or men induced into a negative mood. It is argued that the results reveal the important contribution made to gay men's transmissibility estimates by cognitive strategies (such as the 'availability heuristic' and 'anchoring and adjustment') known to be general characteristics of human information-processing. Implications of the findings for AIDS education are discussed.

This paper reports research regarding the relationship between consumer loyalty, satisfaction,and novelty seeking, including an analysis of these constructs as reflected in the published literature. A telephone survey was conducted of 500 city residents, focusing on their visitation of special events, including sporting events. It was found that satisfaction was somewhat positively related to interest in attending the same sporting event, and the intention to actually visit the sporting event again. However, novelty seeking was virtually unrelated to both interest in attending the same sporting event, and the intention to actually visit the sporting event, and unrelated to satisfaction. Novelty seeking in general, or in relation to special events particularly,performed similarly as a predictor. Further research is needed to clarify the role of other moderating variables, such as the feeling of involvement in sporting events, and to investigate segmentation aspects which might be operating in relation to specific sporting events and tourists.

In this paper we generalize Besag's pseudo-likelihood function for spatial statistical models on a region of a lattice. The correspondingly defined maximum generalized pseudo-likelihood estimates (MGPLEs) are natural extensions of Besag's maximum pseudo-likelihood estimate (MPLE). The MGPLEs connect the MPLE and the maximum likelihood estimate. We carry out experimental calculations of the MGPLEs for spatial processes on the lattice. These simulation results clearly show better performances of the MGPLEs than the MPLE, and the performances of differently defined MGPLEs are compared. These are also illustrated by the application to two real data sets.

This paper treats the problem of fitting general aggregation operators with unfixed number of arguments to empirical data. We discuss methods applicable to associative operators (t-norms, t-conorms, uninorms and nullnorms), means and Choquet integral based operators with respect to a universal fuzzy measure. Special attention is paid to k-order additive symmetric fuzzy measures.

This paper examines the respective roles of trading partner relationships and innovation management practices in predicting product and process related innovation performance. The empirical data were drawn from 194 Australian managers. Data analysis using structural equation modelling indicates that supplier relationships and customer relationships have less impact on product and process innovation performance than do knowledge and creativity management. However, the results also indicate that trading partner relationships have a strong and positive association with innovation management practices, meaning that organisations commonly implement both in a synchronous manner.

This article presents the findings from an empirical study examining the relationship between total quality management (TQM) practices and quality performance in Australian organizations. A comparison is made between organizations that have adopted formal TQM programs and organizations without a formal program in place. It was recognized that the lack of a formal program did not necessarily mean TQM principles were not being practiced. The findings show that the firms adopting formal TQM programs implement several TQM practices at a higher level than those that do not have TQM programs. This difference, however, is not apparent in the case of quality performance. Furthermore, the findings show the strong links between TQM practices and quality performance, and there is no significant difference between organizations implementing formal TQM programs and those organizations simply adopting TQM practices. This suggests that it is the adoption of quality practices that matters rather than formal programs per se.
