Extant research suggests that workplace ostracism has a detrimental impact on the outcomes of employees. However, very little is known about the impact of workplace ostracism on sleep quality. Therefore, this study aimed to address this gap in the literature. By employing the extended stressor-det...

Finally, with a simple linear regression network, a tighter coordinate can be obtained. The main downside of the technique is its computational cost. The network needs to compute a forward pass for every bounding box proposition. The problem with sharing computation across all boxes was that the...
Adopting a unifying theme based on maximum statistics, Multiple Comparisons Using R describes the common underlying theory of multiple comparison procedures through numerous examples. It also presents a detailed description of available software implementations in R. The R packages and source code for the...
