We investigate a simple dynamic model offirm behavior in which firms compete by investing in capacity that is used to provide a good or service to their customers. There is a fixed total market ofcustomers whose demands for the good or service are random and who divide their patronage between the firms in each period. Periodically, the market shares of the two firms can change based on the real...

Aiming at the actuality that the research about costumer service recovery prediction structure is relatively deficient under the background of China culture, based on literature analysis, profound interview, opening investigation and expectation research, we adopt exploratory factor analysis method and confirmatory factor analysis method to develop and validate the scale used to measure custome...

An important factor in the successful deployment of federated web services-based business activities will be the ability to guarantee reliable distributed operation and execution under scalable conditions. For example advanced failure management is essential for any reliable distributed operation but especially for the target areas of web service architectures, where the activities can be const...

This paper introduces the DeltaGrid abstract execution model as a foundation for building a semantically robust execution environment for concurrent processes executing over Delta-Enabled Grid Services (DEGS). A DEGS is a Grid Service with an enhanced capability to capture incremental data changes, known as deltas, associated with service execution in the context of global processes. The abstra...

BACKGROUND Cardiovascular diseases contribute substantially to the poor health and reduced life expectancy of Indigenous Australians. Heart failure is a common, disabling, progressive and costly complication of these disorders. The epidemiology of heart failure and the adequacy of relevant health service provision in Indigenous Australians are not well delineated. METHODS A systematic search ...

Information service users are required to provide personal information to service providers. Accordingly, Personal Information Breach (PIB) and side-effects have recently emerged. This study will seek answers to the following research questions: (1) In a PIB context, which types of PI are regarded as sensitive, and which recovery efforts are important?, (2) What effects do the company’s recover...

Certain gateways (e.g., some cable or DSL modems) are known to have low reliability and low availability. Most failures of these devices can however be “fixed” by rejuvenating the device after a failure has been detected. Such a detection based rejuvenation strategy permits increasing the availability of these gateways. In the considered scenario, rejuvenation is non-trivial since a failure of ...

The correct functioning of a peer-to-peer network relies on cooperative behavior of peers as service providers. Current approaches to detection and deterrence of non-cooperative behavior, such as reputation systems, rely on (1) global sharing of observations about service provisioning and (2) global authentication. These two factors severely impair the practical applicability. We propose a nove...
