Hepatic transport kinetics: Can traditional models open the black box?

Black-box Fault Models

Four black-box fault models are introduced in the paper. The test generation task for the black-box model is more complicated, because possible realizations of the design must be taken into account. However, the time required to generate tests is not very critical factor, because the test generation can be done in parallel with the circuit synthesis process without a prolongation of Time-to-Mar...

Chatter Matters: How Twitter Can Open the Black Box of Online Word-of-Mouth

We collect Word-of-mouth (WOM) data on movies from Twitter and employ both a time-series model and a dynamic panel data model to study the influence of WOM on movie box office revenues. Compared with most previous literature that measures WOM through its volume or dispersion, we directly measure the number of recipients of each WOM message using the unique social structural information on Twitt...

Applications of Abduction #3: \black-box" to \gray-box" Models

Military Operations Research makes extensive use of large complex simulation models. These simulation models are often black-boxes; i.e. they are opaque and incomprehensible. A considerable effort is involved in commissioning a new model into service. We characterise this activity as the construction of gray-box approximate causal models of the functional behaviour of black-box simulation softw...

New Theory Cracks Open the Black Box of Deep Learning

Structuration theory: open the black box of integrated care

Introduction: The health care system is in transition. Integrated cares solutions are prominent and even forced by health care policy. But how can we understand the needs of different stakeholders in this system? Why do they still not act effectively and efficiently together? A closer look, using the structuration theory of Anthony Giddens, may be helpful. Theory: The theory of structuration en...
