Controversy has arisen over interpretation of performance validity tests (PVTs) when multiple PVTs are given. Some papers state that more stringent criteria are needed to judge overall performance as invalid, while others argue that concerns about the number of PVTs are overstated and that widely used criteria are appropriate. We ...

A prediction of a chemical property or activity is subject to uncertainty. Which type of uncertainties to consider, whether to account for them in a differentiated manner and with which methods, depends on the practical context. In chemical modelling, general guidance of the assessment of uncertainty is hindered by the ...

A game-theoretic model is developed where an infrastructure of N targets is protected against terrorism threats. An original threat score is determined by the terrorist's threat against each target and the government's inherent protection level and original protection. The final threat score is impacted by the government's additional protection. We ...

Normal mode analysis (NMA) is an important tool for studying protein dynamics. Due to the complexity of conventional NMA that employs an all-atom model and a semi-empirical force field, many simplified NMA models have been developed, some of which are known as elastic network models. The quality of these simplified ...

Whether overt attention in natural scenes is guided by object content or by low-level stimulus features has become a matter of intense debate. Experimental evidence seemed to indicate that once object locations in a scene are known, salience models provide little extra explanatory power. This approach has recently been criticised ...

We propose a novel framework of using a parsimonious statistical model, known as mixture of Gaussian trees, for modeling the possibly multimodal minority class to solve the problem of imbalanced time-series classification. By exploiting the fact that close-by time points are highly correlated due to smoothness of the time-series, our ...

Laska, Gurman, and Wampold (2014, pp. 467-481) present their common factors (CF) model as an alternative/complement to existing empirically supported treatments. The CF model is largely based on nonrandomized studies and a post hoc interpretation of a lack of differences between psychotherapies in their outcomes. Our view is that the ...

Subordinates are often seen as impotent, able to react to but not affect how powerholders treat them. Instead, we conceptualize subordinate feedback as an important trigger of powerholders' behavioral self-regulation and explore subordinates' reciprocal influence on how powerholders allocate resources to them over time. In 2 experiments using a multiparty, ...
