A relatively small yet diverse group of plants are capable of sequestering metals in their shoot tissues at remarkably high concentrations that would be toxic to most organisms. This process, known as metal hyperaccumulation, is of interest for several reasons, including its relevance to the phytoremediation of metal-polluted soils. Most research on… (More)
Sleeping sites are an important aspect of an animal's ecology given the length of time that they spend in them. The sleep ecology of wild saddleback and mustached tamarins is examined using a long-term data set covering three mixed-species troops and 1,300+ tamarin nights. Seasonal changes in photoperiod accounted for a significant amount of variation in… (More)
We propose simple tangible language elements for very young children to use when constructing programmes. The equivalent Turtle Talk instructions are given for comparison. Two examples of the tangible language code are shown to illustrate alternative methods of solving a given challenge.
We present two technology-augmented physical materials that illetterate coders can sculpt for use as physical syntax elements in a tangible early-programming learning environment. Two physical coding sequences are given. We conclude with the listing of further work required.
The study of expertise in surgery aims to facilitate the development of improved training methods by understanding the characteristics of expert practitioners. In this article and its companion, we present our study of the characteristics of competence and expertise in the field of oral surgery. We observed participants of different skill levels as they… (More)
Good visual perception skills are important in the effective manipulation of Tangible User Interfaces. This paper reports on the application of a test set we have developed specifically to quantify the visual perception skills of children when matching a physical object to its flat representation on paper. A pilot evaluation, with two groups of children… (More)

The Internet of Things (IoT) holds the promise of improved programmatic user control over domestic appliances. The developed world dominates the design of programming environments, assuming letteracy and computer literacy on the part of the programmer. In developing areas, this assumption raises the bar for novice programmers and especially pre-school… (More)
Studies of primate taxonomy and phylogeny often depend on comparisons of limb dimensions, yet there is little information on how morphology correlates and contributes to foraging strategies and ecology. Callitrichid primates are ideal for comparative studies as they exhibit a range of body size, limb proportions and diet. Many callitrichid species exhibit a… (More)
