Previous work investigating the performance of genetic algorithms (GAs) has attempted to develop a set of fitness landscapes, called “Royal Roads” functions, which should be ideally suited for search with GAs. Surprisingly, many studies have shown that genetic algorithms actually perform worse than random mutation hill-climbing on these landscapes, and several different explanations have been o...

We automate the organization of GPS data to create a visibility map with correctly connected intersections. For our example case study, we use GPS data collected on the Swarthmore College campus. After the data is automatically organized and cleaned, a user is able to select points on a visual map to search for an optimal path between those points. 1 The Problem of Navigation Swarthmore College...

Higher education plays a crucial role in supporting society based on sustainable development through the facilitation of students’ acquisition competencies for development. A suitable arena which to integrate these can be courses built project-based learning, though knowing how support learning difficult and continued challenge. In this work, we study first second year bachelor level PBL examin...

1. The superficial muscle fibres in the proximal head of the closer muscle in the crab Eriphia belong to four distinct fibre types (I-IV). By stimulating either the 'slow' or the 'fast' axon, facilitation properties of the EJPs were investigated in eight identifiable muscle fibres which represented the four fibre types. 2. Amount, time course and frequency dependence of facilitation (f) of both...

Temporal encoding in Pavlovian fear conditioning was examined through conditional facilitation of the short-latency (Rl) component of the rat eyeblink reflex. Rats were fear-conditioned to a tone conditional stimulus (CS) with either a 3- or 9-s interstimulus interval (ISI) between CS onset and the onset of the grid-shock unconditional stimulus (US). Rl facilitation was tested over 2 days, in c...

With universities having difficulty attracting students to study information technology (IT), the scores needed for entry into IT degrees have dropped markedly. IT schools are thus having to cope by adjusting their introductory courses to ensure that students will still learn what is expected but without negatively impacting on pass rates. This paper considers short objective tests, designed by...

BACKGROUND Accrediting bodies require medical schools to teach patient safety and residents to develop teaching skills in patient safety. We created a patient safety course in the preclinical curriculum and used continuous quality improvement to make changes over time. OBJECTIVE To assess the impact of resident teaching on student perceptions of a Patient Safety course. DESIGN Using the Ins...
