Land and sea surface temperatures, precipitation, and storm tracks in North America and the North Pacific are controlled to a large degree by atmospheric variability associated with the Pacific North American (PNA) pattern. The modern instrumental record indicates a trend toward a positive PNA phase in recent decades, which has led to accelerated warming and snowpack decline in northwestern Nor...

The ability to self regulate is a key skill in learning. This is especially relevant for open learning environments such as MOOCs. Metacognitive sca↵olding refers to computer based support is used to teach and engage users in metacognition and self regulated learning. These techniques have been found very useful in supporting students in e-learning environments. Studies in game based learning s...

Discussion forums in massive open online courses (MOOCs) are a primary means of interaction among learners and instructors. Despite their widespread use there is concern that forums are not an effective means of promoting engagement and learning. This paper examines issues relating to forums through a brief literature review and by drawing on data from a specific MOOC run by the University of W...

This paper describes the design and development of an online immersive learning environment focused on supporting the general public in awareness of, and preparation for, crisis situations. The system developed uses the PANDORA + training environment, and integrates prior research work carried out on eLearning and Crisis Management. Specifically, it pulls together the outputs of three European ...

This paper describes a new approach to feedback equalization for hearing aids. The method involves the use of an adaptive algorithm that estimates and tracks the characteristic of the hearing aid feedback path. The algorithm is described and the results of simulation studies and bench testing are presented.

The American Academy of Pediatrics (AAP) launched the Pediatrician Life and Career Experience Study (PLACES), a longitudinal study that tracks the personal and professional experiences of early career pediatricians, in 2012. We used a multipronged approach to develop the study methodology and survey domains and items, including review of existing literature and qualitative research with the tar...

We describe the participation of the University of Amsterdam’s ILPS group in the Knowledge Base Acceleration and Microblog tracks at TREC 2012.

Debate about the function of the hippocampus often pits theories advocating for spatial mapping against those that argue for a central role in memory. This review addresses whether research in the monkey supports the view that processing spatial information is fundamental to the function of the hippocampus. In support of spatial processing theories, neurons in the monkey hippocampal formation h...

The e¡ect of dredging on bottom structure was assessed, to estimate the damage in£icted on the benthic macrofauna left on the dredge path and to evaluate aggregations of scavengers within the track. Sediment suspended during dredging rapidly resettled both on sand and sandy-mud bottoms. Dredge tracks were deeper on sandy-mud sediments and persisted longer than in sandy sediments. The disappeara...

A commonly known and widely studied problem of massive open online courses (MOOCs) is the high drop-out rate of students. In this paper we propose and analyze the composition of small learning groups as a solution to this problem. In an experiment, we composed such small learning groups in a MOOC context using two methods: Random grouping and grouping by an algorithm that considers selected stu...
