Rule extraction from technology IPOs in the US stock market

Machine learning techniques for prediction and rule extraction from artificial neural network methods are used. The hypothesis that market sentiment and IPO specific attributes are equally responsible for first-day IPO returns in the US stock market is tested. Machine learning methods used are Bayesian classifications, support vector machines, decision tree techniques, rule learners and artificial neural networks. The outcomes of the research are predictions and rules associated With first-day returns of technology IPOs. The hypothesis that first-day returns of technology IPOs are equally determined by IPO specific and market sentiment is rejected. Instead lower yielding IPOs are determined by IPO specific and market sentiment attributes, while higher yielding IPOs are largely dependent on IPO specific attributes.

Understanding service failure and recovery: A customer-based phenomenographic approach

To date, researchers have largely considered service failure and recovery as a combination of individual constructs, often in isolation, rather than viewing failure and recovery holistically. Consequently, our understanding is fragmented. Furthermore, while some attempt has been made to gain a better understanding of service failure and recovery from both the customer and the employee’s perspective (cf. Bitner et al.1990; McColl-Kennedy and Sparks 2003), no study has employed an interpretative perspective that potentially offers a rich, in-depth approach to this important area of research. Given this gap, our paper presents the value of taking a customer-based interpretive approach to obtaining a fuller understanding of the way customers view service failure and recovery. In this paper we report the findings of our phenomenography study of twenty in-depth interviews. Not only do we argue the benefits of adopting this fresh approach to studying service failure and recovery, we also present an innovative conceptual framework derived from our phenomenographic research findings, which has significant theoretical and practical implications.

Customers as spatial and social influencers on other customers in the social-servicescape

In marketing, considerable attention has been devoted both to the understanding of consumer behaviour and the impact of the physical environment on the behaviour of consumers within these settings. Yet surprisingly, little attention has been given to the influence of customers on other customers in such settings. But within the environment it could be argued that social stimuli are likely to receive more attention than non-social or physical stimuli (Guerin, 1993). Psychologists have asserted that the mere presence (or absence) of people will affect the behaviour of others. Thus we argue in this paper that customers impact on other customers within the social servicescape. This paper presents the findings of an observational study of 225 episodes which took place within a selected servicescape - four cafes. We found that the presence of other customers appeared to positively influence duration of the stay (social influence), and that customers appeared to exhibit a desire for the presence of other customers in this social setting in that customers appeared to be drawn spatially to where customers were already seated (spatial influence). We draw from psychology, in particular, social facilitation theory (Platania and Morin, 2001; Zajonc, 1965), affiliative conflict theory (Argyle and Dean 1965; Knowles 1980, 1989) and from psychology and sociology in terms of the basic emotional need for a “sense of belonging” (Hagerty, Williams and Oe 2002) in order to develop the conceptual framework for this study. Theoretical and managerial implications of our findings are discussed, as well as directions for further research.

An examination of the effect of sponsorship stimuli on consumer perceptions of concrete and abstract brand attributes

A Solomon four-group experiment, controlling for order effects, examined the effect of a sponsorship stimulus on consumers’ perceptions of concrete and abstract brand attributes. Results for this study suggested that consumers who are aware of an association between an event sponsorship and a brand demonstrate more favorable perceptions of abstract brand attributes than those who are unaware of such an association. The same favourable perceptions were not found for concrete brand attributes.
