Risk assessment is now regarded as a necessary competence in psychiatry. The area under the curve (AUC) statistic of the receiver operating characteristic curve is increasingly offered as the main evidence for accuracy of risk assessment instruments. But, even a highly statistically significant AUC is of limited value in clinical practice.

Despite the fact that waterjets have become relatively extensively used for industrial cleaning, and are beginning to find increasing use in mining and civil excavation, little is reported on the risks associated with the use of this new tool to the operator. Regulations on the use of waterjets do not indicate an awareness of the relatively low pressures necessary to inject fluid under the skin...

The POLST paradigm has come under fire in two recent articles. This has directly resulted in a few church leaders expressing to CEOs of Catholic health care facilities in their dioceses their grave concerns about the use of POLST in those facilities. Needless to say, this is causing considerable consternation where POLST is already being employed as well as among those who are actively planning...

If the system under test interacts with its environment at physically distributed ports, there is a separate independent tester at each port, and there is no global clock then we are testing in the distributed test architecture. It is known that the distributed test architecture can lead to additional controllability problems in which a tester cannot know when to send an input and this has led ...

Habitat suitability and the distinct mobility of species depict fundamental keys for explaining and understanding the distribution of river fishes. In recent years, comprehensive data on river hydromorphology has been mapped at spatial scales down to 100 m, potentially serving high resolution species-habitat models, e.g., for fish. However, the relative importance of specific hydromorphological...

The art of performance tuning is, alas, still an art; there are few tools to help predict the effects of changes that are motivated by performance needs. In this work, we present dynamic dependency modeling techniques for predicting the effects of configuration changes. These techniques utilize a simple, exterior model of the system under test, and only require codifying the nature of dependenc...
