PURPOSE Cardiovascular disease is the leading cause of mortality and morbidity in the United States. Primary care teams can be best suited to improve quality of care and lower costs for patients with cardiovascular disease. This study evaluates the associations between primary care team communication, interaction, and coordination (ie, social networks); quality of care; and costs for patients w...

In traditional supply chain inventory management, orders are the only information firms exchange, but information technology now allows firms to share demand and inventory data quickly and inexpensively. We study the value of sharing these data in a model with one supplier, N identical retailers, and stationary stochastic consumer demand. There are inventory holding costs and back-order penalty...

In 2001, $13 million were invested in various grape and wine R&D programs via the Australian Grape and Wine Research and Development Corporation. Half of the funds come from compulsory levies from grape-growers and winemakers, and the other half from Commonwealth government matching grants. These funds are then allocated to research projects across broad areas such as grape production R&D, wine...

Data prefetching is an important part in increasing the performance of the majority of programs written. Most of the designs for data prefetchers today try to find patterns in the data access. Other prefetchers attempt to correlate addresses, so that the access to one address is indicative of another access to a different address in the near future. Multi-threaded programs use locks or barriers...

Recently, there has been increased interest in information sharing among government agencies, with a view toward improving security, reducing costs and offering better quality service to users of government services. In this work, the authors complement earlier work by proposing a comprehensive methodology called IAIS (Inter Agency Information Sharing) that uses XML to facilitate the definition...

As new network services emerge, questions about service deployment and network choices arise. Although shared networks, such as the Internet, offer many advantages, combining heterogeneous services on the same network need not be the right answer as it comes at the cost of increased complexity. Moreover, deploying new services on dedicated networks is becoming increasingly viable, thanks to vir...

We analyze the costs and benefits of allowing stakeholders in a firm to share control. In our model, there are conflicts among stakeholders and bargaining does not always lead to efficient decision-making. Although the logic of the Coase Theorem is such that bargaining problems lower the efficiency of decision-making regardless of who has control, we show that conflicts among parties favor undi...

Communication failures are a significant contributor to medical errors that harm patients. Critical care delivery is a complex system of inter-professional work that is distributed across time, space, and multiple disciplines. Because health-care education and delivery remain siloed by profession, we lack a shared framework within which we discuss and subsequently optimize patient care. Further...

Requirements elicitation is a critical phase in information systems development (ISD), having significant impacts on software quality and costs. Prior research suggests that it is a collaborative activity, where system requirements-related knowledge is extensively shared between users and analysts. This knowledge sharing can get extremely tenuous given the different knowledge perspectives of th...
