A Modified Bayesian Power Prior Approach with Applications in Water Quality Evaluation
… monitoring data is too small to have adequate power. Here, we present a Bayesian power prior approach by incorporating the current data and historical data and/or the data collected at neighboring stations to make stronger statistical inferences on the parameters of interest. The elicitation of …

Bayesian Methods for the Design and Analysis of Cluster Randomised Controlled Trials
… a novel application of an informative class of prior distribution, the power prior, is proposed whereby information is borrowed from continuous, clustered, historical data, such as that from a pilot or feasibility study. The performance of this approach is evaluated, and superiority, in …

Development of Informative Priors in Microarray Studies
… data because of their ability to integrate prior information; however, most current Bayesian analyses use empirical or flat priors. We present a Perl script to build an informative prior by mining online databases for similar microarray experiments. Four prior distributions are investigated: …

Being a ‘model’ student: the impact of affective influences on full-time undergraduate student behaviours and practices in the current Higher Education context in England
… biopolitical influence and distribution of power amongst constantly evolving actors within English Higher Education. Findings demonstrate how this framing enables a timely and nuanced perspective on the ways such influences shape the ‘model’ student and their negotiation of networks of …

Shifting alliances and fairweather friends: Luso-American relations, 1941--1951
… time--demanded the protection of a great naval power. Prior to World War II, Luso-American relations were based on long, but tenuous, commercial ties and a small steady Portuguese immigration stream to the United States. Portugal's importance during WWII lay in her geographical position, …

A domain-general perspective on medial frontal brain activity during performance monitoring
… elicited similar changes across MFNs and theta power. In the final study, we converted our response cueing paradigm into a saccade cueing task in order to examine the oscillatory dynamics of response preparation. We found that, compared to easy pro-saccades, successfully preparing a difficult …

Improving the efficiency of clinical trial designs by using historical control data or adding a treatment arm to an ongoing trial
… estimates, inflated type I error and reduced power. We propose two novel weights to assess agreement between the current and historical control data: a probability weight based on tail area probabilities; and a weight based on the equivalence of the historical and current control data …

Novel Bayesian Adaptive Clinical Trial Designs In Early Phases
… The CRM needs pre-specification of a series of prior guesses of toxicity probabilities of each investigated doses, known as the skeleton, using a parametric model, and then continuously updates the estimate of the dose-toxicity curve based on accumulating data. By using a dose-toxicity model, …

The Changing Face of Conventional Air Power
Prior to the Gulf War, American air power strategy was based on the AirLand Battle doctrine, which supported ground forces by concentrating on theater targets and objectives. Since the Gulf War the focus of air power has shifted from supporting ground forces to attacking national strategic assets, …
