ÐIn the literature, the PnP problem is indistinguishably defined as either to determine the distances of the control points from the camera's optical center or to determine the transformation matrices from the object-centered frame to the camera-centered frame. In this paper, we show that these two definitions are generally not equivalent. In particular, we prove that, if the four control point...

P4P: A Practical Framework for Privacy-Preserving Distributed Computation

Current strategies for addressing health care costs stress physician performance measurement and commonly use an efficiency index (EI). During seven years of conducting individual practitioner pay-for-performance (P4P), we found that using EIs hindered our work on reducing overuse of services. This paper offers an alternative approach through the identification of variation in key cost drivers....

We study physicians’ incentives to use personalised medicine techniques, replicating the physician’s trade-offs under option of information. In a laboratory experiment conducted in two French Universities, prospective physicians played real-effort game. vary both information structure (free access versus paid information) and payment scheme (pay-for-performance (P4P), capitation (CAP) fee-for-s...

Blockchain is a mainstream technology in which many untrustworthy nodes work together to maintain distributed ledger with advantages such as decentralization, traceability, and tamper-proof. The network layer communication mechanism its architecture the core of networking method, message propagation, data verification among blockchain nodes, basis ensure blockchain’s performance key features. W...

The Medicare Physician Group Practice (PGP) demonstration is Medicare's first physician pay-for-performance (P4P) initiative. The demonstration, which is legislatively mandated, establishes incentives for quality improvement (QI) and cost efficiency at the level of the PGP Ten large physician groups are participating in the demonstration, which started on April 1, 2005, and will run for 3 years...

The market of energy services for the residential sector in Europe is very limited at present. Various reasons can be argued such as high transaction costs a highly fragmented and low consumption per dwelling. rather long payback time investments render Energy Services Companies’ (ESCOs) financially unattractive many ESCOs building residents, thus hindering large potential savings that responsi...

BACKGROUND Rewarding provider performance has been recommended by the Institute of Medicine as an approach to improve the quality of treatment, yet little empirical research currently exists that has examined the effectiveness and cost-effectiveness of such approaches. The aim of this study is to test the effectiveness and cost-effectiveness of providing monetary incentives directly to therapis...

risks and how to evaluate healthcare contracts? The research questions in this series of three articles focus on how reimbursement strategies (especially Pay for Performance P4P), evaluation of measures and methods of risk adjustment can best be integrated in healthcare contracting. This last article of the series will spot light on the specific topic of risk adjustment as well as evaluation an...
