Abstract: The recent profusion of smartphones in the mobile industry offers new opportunities for mobile services vendors. One of the most influenced service categories is location-based services (LBS). Based on insights from behavioural decision-making, a theoretical framework is developed to analyse individuals‟ decisions to use LBS. We focus on the cognitive processes involved in individual decisionmaking. Our research is based on two studies. First, we investigated the use of LBS through semistructured interviews of smartphone users. Second, we explored daily LBS use through a study based on diaries. The findings highlight the distinct value dimension in specific contexts of use and the positive experiences of the service as the main drivers of LBS use. Thus, the user decision to use LBS can be described by either a comparative mode based on the value of LBS in relation to other available options, or by an intuitive mode where past experiences trigger the use of heuristics. These modes in turn underscore the positive influences on the continuance of LBS use. URI: http://hdl.handle.net/10398/8522 Files in this item: 1

Abstract: The continuance of use is an important topic of IS research. However, in the past, many researchers have focused on adoption rather than IS continuance. Studying continuance is of equal importance, because if use does not persist, this may limit the revenues of the provider. This is particularly true for consumer-oriented services, which rely on advertising, or subscription-based revenue models. In this paper, we investigate the determinants of location-based services (LBS) continuance as a relevant case study for the examination of IS continuance generally. A research model is developed and empirically tested through a survey of a representative sample in Germany. The proposed model builds on and extends the Limayem et al. model of IS continuance. Our analysis highlights the importance of habit and emotion in LBS continuance. The results indicate that habit has a stronger predictive power than continuance intentions for LBS continuance and that emotions are an important driver for user satisfaction with LBS.

How knowledge workers act as amateurs when using information at workConstantiou, Ioanna; Madsen, Sabine; Papazafeiropoulou, Anastasia (, 2011)[More information][Less information]
Abstract: The proliferation of Internet technologies in the workspace provides tremendous possibilities for knowledge workers to access vast amounts of information from a large number of sources. The information abundance offers new opportunities which empower the knowledge worker but at the same time may create information overload. This study explores academics’ information management practices, by applying a theoretical framework build on three theoretical perspectives. These involve mindfulness, sense-making, and decision-making heuristics. The theoretical framework is used to analyse diary data about three tasks: email management, communication with colleagues, and information search. Our findings show that the knowledge workers have developed their own relatively simple but seemingly suitable practices for dealing with information overload and being empowered from the abundant information available to them. The relative amateurism and professionalism of the participants are discussed and limitations of this study as well as areas for future research are delineated.

A model of individual decisions for digital product product acquisitionVeitch, Robert W. D.; Constantiou, Ioanna (Frederiksberg, 2011)[More information][Less information]
Abstract: Ten years after the fall of Napster, digital piracy remains an issue for media and software companies. While scholars often treat digital piracy as a behaviour that needs to be prevented or punished, the user’s decision about how to acquire a digital product involves more than the piracy option. However, the decision between legal alternatives and piracy has received limited attention. Moreover, existing models used in piracy research emphasize some elements of the acquisition decision, but disregard other important influences. This has led to a body of literature that is fragmented and has decontextualised digital piracy by not examining how available legal alternatives are evaluated. This paper makes an attempt to address these issues and presents a model of the user’s digital product acquisition decision in the context of piracy, integrating elements of previous models to reflect the decision’s complexity. Specifically, we use a consumer decision-making perspective as a framework for integrating elements of previous models used in digital piracy research, including those from social psychology, business ethics, criminology, and consumer behaviour. In the model, we depict the acquisition decision as being influenced by the user’s product desire, price perceptions, perceived risks, internal regulators of behaviour, resources, and product availability. Theoretical and empirical evidence from the existing literature is drawn upon in order to provide support for the elements of the model. The paper concludes with an outline for future research and a brief discussion of its contribution. URI: http://hdl.handle.net/10398/8500 Files in this item: 1

Comparing digital piracy to legal alternatives for film and musicVeitch, Robert; Constantiou, Ioanna (Frederiksberg, 2012)[More information][Less information]
Abstract: Technologies enabling digital piracy have expanded the variety of options available to users when deciding how to access a product. As a result, access-mode decisions for film and music are broader than for other goods where the piracy option is not as prevalent. This paper presents a model of access-mode decisions for film and music which integrates elements of previous digital piracy models and expands upon them to reflect the decision?s complexity. We depict the access-mode decision as being influenced by the user?s product desire, price perceptions, perceived risks, internal regulators of behaviour, resources and legal availability. We test the model for film and music using causal data of access-mode decisions collected from students at two Danish universities. Our findings indicate that the economic considerations of price perception and legal availability are the most consistent factors in influencing the access-mode decision across different legal options. The paper concludes with an outline for future research. URI: http://hdl.handle.net/10398/8569 Files in this item: 1
