introduction: direct observation of procedural skills (dops) is a way of evaluating procedural skills through observation in the workplace. the purpose of this study was to assess the role of dops in teaching and assessment of postgraduate students and to know the effect of repeated dops on improvement of the skills and confidence of the students. methods: this prospective study was conducted i...

Theories of procedural justice suggest that individuals who experience respectful and fair legal decision-making procedures are more likely to believe in the legitimacy of the law and, in turn, are less likely to reoffend. However, few studies have examined these relationships in youth. To begin to fill this gap in the literature, in the current study, the authors studied 92 youth (67 male, 25 ...

We present a deep learning approach for speeding up constrained procedural modeling. Probabilistic inference algorithms such as Sequential Monte Carlo (SMC) provide powerful tools for constraining procedural models, but they require many samples to produce desirable results. In this paper, we show how to create procedural models which learn how to satisfy constraints. We augment procedural mode...

Ecstasy/MDMA use has been associated with various memory deficits. This study assessed declarative and procedural memory in ecstasy/MDMA users. Participants were tested in two sessions, 24 h apart, so that the memory consolidation function of sleep on both types of memory could also be assessed. Groups were: drug-naive controls (n1⁄4 24); recent ecstasy/MDMA users, who had taken ecstasy/MDMA 2–...

Shortly after its introduction in 1985, procedural solid texturing became a must-have tool in the production-quality graphics of the motion-picture industry. Now, over fifteen years later, we are finally able to provide this feature for the real-time consumer graphics used in videogames and virtual environments. A texture atlas is used to create a 2-D texture map of the 3-D solid texture coordi...

BACKGROUND Only recently have data been published attempting to validate a technology and technique suitable for targeted delivery of biological payloads to the human spinal cord. OBJECTIVE To characterize the development and evolution of a spine-stabilized microinjection platform as a vehicle for biologics delivery to the cervical and thoracolumbar spine on the basis of preclinical experienc...

The placement of vegetation plays a central role in the realism virtual scenes. We introduce procedural models (PPMs) for urban layouts. PPMs are environmentally sensitive to city geometry and allow identifying plausible plant positions based on structural functional zones an layout. can either be directly used by defining their parameters or learned from satellite images land register data. Th...

Procedural learning of skills depends on dopamine-mediated striatal plasticity. Most prior work investigated single stimulus-response procedural learning followed by feedback. However, many skills include several actions that must be performed before feedback is available. A new procedural-learning task is developed in which three independent and successive unsupervised categorization responses...
