BACKGROUND A ubiquitous issue in research is that of selecting a representative sample from the study population. While random sampling strategies are the gold standard, in practice, random sampling of participants is not always feasible nor necessarily the optimal choice. In our case, a selection must be made of 12 hospitals (out of 89 Dutch hospitals in total). With this selection of 12 hospi...

We contrasted the effects of different types of working memory (WM) load on detection. Considering the sensory-recruitment hypothesis of visual short-term memory (VSTM) within load theory (e.g., Lavie, 2010) led us to predict that VSTM load would reduce visual-representation capacity, thus leading to reduced detection sensitivity during maintenance, whereas load on WM cognitive control processe...

C ivil engineers are often very conservative in how they pursue their profession-and for good reason: If their designs don't work, things can fall down and kill people (as the recent bridge collapse in Minnesota so clearly demonstrates). Following novel approaches increases the probability of making such disastrous mistakes. It can therefore be prudent to build on designs that are known to func...

participation and rule of collective wisdom and ranchers’ involvement in decisions has become common practice nowadays. sustainable development can be followed through targeting and leading participation to the preservation and restoration of natural resources. so, participation concepts and its effective factors have to be investigated carefully. this study was conducted to investigate the soc...

such problems the students were top (23% failures), house officers second (35%), and, surprisingly, nurses bottom (70%).8 Bridges and Goldberg in their paper in this week's BMJ speak of neurologists, but it is not clear whether they are referring to the consultants or to the registrars, and it will be impossible to decide who recognised or failed to recognise a psychiatric component in the pati...

Perceptual learning of visual features occurs when multiple stimuli are presented in a fixed sequence (temporal patterning), but not when they are presented in random order (roving). This points to the need for proper stimulus coding in order for learning of multiple stimuli to occur. We examined the stimulus coding rules for learning with multiple stimuli. Our results demonstrate that: (1) sti...
