The attributes of value co-creation in service and its impact on customers' willingness to pay. Observations from three service industries.

Marketing literature has propagated “customer-participation” and “co-production” in the seller-buyer framework since the 1970s (Lovelock and Young 1979), yet marketing knowledge gaps exist in this area. Recent management research emphasise the need to re-evaluate how value is created for consumers and to consider the close nature of the interactions between buyers and sellers (Payne et al 2008). Vargo and Lusch’s (2004) proposed service-dominant logic reiterates this need, arguing that the “customer is always the co-creator of value”, as they are part of the system that delivers value. Understanding value co-creation is then important to management research, as it uncovers new opportunities to create “value” for customers. This also enables firms to formulate better pricing strategies. This thesis examines value co-creation attributes and how they may impact on the customer’s willingness to pay. Three studies utilising qualitative and quantitative methods have been conducted to address the research question. The first two studies employed qualitative methods to derive insights into value co-creation attributes from a comparative case study perspective under two different service contexts; the defence and healthcare industries. The third study, conducted under the higher education context, employed quantitative methods to gauge the impact of value co-creation attributes on the customers’ willingness to pay. The qualitative studies found six generic value co-creation attributes, while the quantitative study empirically verified the importance of value co-creation attributes and the fact that they may impact on the customer’s willingness to pay for a service. This thesis validates that value co-creation is important in service provision. As customers become increasingly informed and empowered, a deeper understanding of how customers co-create value with the firm is then central to marketing activities, specifically in how firms design and price their services. Therefore, this thesis contributes to marketing knowledge by proposing value co-creation attributes that have both theoretical and managerial implications

A performance study of packet scheduling algorithms for coordinating colocated Bluetooth and IEEE 802.11b in a Linux machine

Due to the proliferation of hand-held short-range communication devices, coexistence between Bluetooth and IEEE 802.11b has become a performance critical issue. In this study, we performed an actual implementation of a Linux based network access point (NAP), in which Bluetooth and IEEE 802.11b are colocated. Such a NAP is expected to be crucial in supporting 'hot-spot' systems targeted to serve nomadic users carrying either a Bluetooth or a IEEE 802.11b device. Specifically, the goal of our study is to investigate the efficacy of a software based interference coordination approach. We consider five most commonly used scheduling algorithms in a Linux environment. Our extensive experimental results obtained in a real environment indicate that a hierarchical scheduling approach exhibits the best performance in terms of aggregate bandwidth achieved by Bluetooth and IEEE 802.11b.published_or_final_versio

Assessment of Bridge Inspection and Maintenance in the United States

Bridge inspection and maintenance is extremely important to the country since it is the economic lifeblood of the United States business and people relying upon them to do business and get to work. Although bridge disasters are relatively rare, the consequence of a failure can be disastrous. Technical and management problems that under the identification of bridge deficiency and obsolesce need to be identified and solved in order to keep bridges from falling apart. The purpose of this paper is to understand the problem behind bridge inspection and maintenance system in the United States in order to develop potential solutions to solve the problems that the DOTs are facing on the aging bridges and limited budget. A cost management model and a maintenance spending model are analyzed from this research
