Collaborative Virtual Environment to Facilitate Game Design Evaluation with Children with ASC

ABSTRACT

Involvement of children with autism spectrum conditions (ASC) in the design of new educational technology is becoming more prevalent. Despite potential barriers due to communication and ideation difficulties for children with ASC, adapted participatory design methods can successfully facilitate their direct involvement. Nonetheless, methods requiring face-to-face communication can still be difficult for children with ASC and research suggests that technology mediation could facilitate their contribution. This study explores the use of collaborative virtual environments (CVEs) as a medium through which students evaluated existing computer games and offered suggestions for game development. CVEs in which the users were represented by (a) avatars and (b) video-pods were compared to a face-to-face condition. Twelve typically developing (aged 8–9 years), 12 higher ability ASC (12–14) and 4 lower ability ASC children (12–14) participated. All student groups preferred the video-pod CVE and students with ASC were generally better able to contribute effectively through this medium than face-to-face.     

Transport disadvantage within aboriginal communities in an urban environment

Recent research into the transport needs of three Aboriginal communities in Sydney, Australia, has shown that in certain circumstances several of their members experienced disadvantage that differed from non-Aboriginal transport users. This difference is driven by transport needs that relate to cultural activity. It is suggested that mobility for Aboriginal people who live in an urban environment is linked to their cultural survival.     

Differences in Effects of Pyrrolizidine Alkaloids on Five Generalist Insect Herbivore Species

The evolution of the diversity in plant secondary compounds is often thought to be driven by insect herbivores, although there is little empirical evidence for this assumption. To investigate whether generalist insect herbivores could play a role in the evolution of the diversity of related compounds, we examined if (1) related compounds differ in their effects on generalists, (2) there is a synergistic effect among compounds, and (3) effects of related compounds differed among insect species. The effects of pyrrolizidine alkaloids (PAs) were tested on five generalist insect herbivore species of several genera using artificial diets or neutral substrates to which PAs were added. We found evidence that structurally related PAs differed in their effects to the thrips Frankliniella occidentalis, the aphid Myzus persicae, and the locust Locusta migratoria. The individual PAs had no effect on Spodoptera exigua and Mamestra brassicae caterpillars. For S. exigua, we found indications for synergistic deterrent effects of PAs in PA mixtures. The relative effects of PAs differed between insect species. The PA senkirkine had the strongest effect on the thrips, but had no effect at all on the aphids. Our results show that generalist herbivores could potentially play a role in the evolution and maintenance of the diversity of PAs.     

Uncovering sexuality and gender: an intersectional examination of women’s experience in UK construction

UK employers have been broadening their equality and diversity activities to include the issue of sexual orientation; however, the construction industry has been slow to follow. Equally there is a lack of research on the experiences of lesbian, gay, bisexual and transgender (LGBT) workers in construction. While women’s sexuality soon becomes a focus of interest when they enter male-dominated work, little research has discussed how sexual minorities–and in particular lesbians–fare in such environments. This article examines how both gender and sexuality interact to shape women’s working lives within the UK construction sector, drawing on 22 interviews and a focus group with heterosexual women and lesbians in male-dominated occupations in construction. While women share common experiences of heightened interest and questioning, open lesbians can sometimes minimize the sexualized content of workplace interactions. However the potential for exclusion on the basis of minority sexuality also exists. Sexual harassment appears less prevalent for women in professional occupations than in the past, while women in the manual trades reported that the problem persists. Lesbians can experience different forms of harassment, however, from heterosexual women, while employers are less developed in their response to homophobic harassment.     

Kernel density estimation and K-means clustering to profile road accident hotspots

Identifying road accident hotspots is a key role in determining effective strategies for the reduction of high density areas of accidents. This paper presents (1) a methodology using Geographical Information Systems (GIS) and Kernel Density Estimation to study the spatial patterns of injury related road accidents in London, UK and (2) a clustering methodology using environmental data and results from the first section in order to create a classification of road accident hotspots. The use of this methodology will be illustrated using the London area in the UK. Road accident data collected by the Metropolitan Police from 1999 to 2003 was used. A kernel density estimation map was created and subsequently disaggregated by cell density to create a basic spatial unit of an accident hotspot. Appended environmental data was then added to the hotspot cells and using K-means clustering, an outcome of similar hotspots was deciphered. Five groups and 15 clusters were created based on collision and attribute data. These clusters are discussed and evaluated according to their robustness and potential uses in road safety campaigning.     

The Body, the Temple and the Newtonian Man Conundrum

From his early days at the University of Cambridge until his death, Isaac Newton had a long running interest in the Temple of Solomon, a topic which appeared in his works on prophecy, chronology and metrology. At the same time that Newton was working on the Principia, he reconstructed the Temple and commented on the reconstructions of others. An important part of his investigations concerned the measurements of the Temple, which were harmonic and were built “exactly as the proportion of architecture demands.” Newton considered these proportions to be in accordance with Book III and IV of De Architectura. However, while insisting on exact architectural proportions, Newton moved away from the traditional proportions of the Vitruvian man; he derived a Newtonian man. This poses an interesting conundrum: Newton accepted the Temple’s architectural proportions as outlined in Vitruvius’s Book III, yet he rejected the human model Vitruvius used as the foundation of these proportions. At the same time Newton accepted the human frame as the basis of all ancient measurements and attempted to estimate the length of the sacred cubit based on the lengths of the parts for the body and the measurements set out by the ancient writers such a Vitruvius.
