A model of a pumped continuous atom laser

We present a model of a cw atom laser based on a system of coupled GP equations. The model incorporates continuous Raman outcoupling, pumping and three-body recombination. The outcoupled field has minimal atomic density fluctuations and is locally monochromatic.Comment: 10 pages, 8 eps figures, typos fixe

Re-appraising the Museum's Pedagogic Purpose in an Age of Uncertainty

As we enter the third decade of the twenty-first century, in which the assuredness and authority of the modern period has been eclipsed by the uncertainty of our global age, I reflect on aspects of the public museum's legacy for learning. I argue for greater recognition of the contested pedagogic purposes with which pubic museums have been tasked and I position twenty-first century'disruptions' such as protests, interventions and contestations, directed at the practices of public museums, as having important pedagogic intentions and effects . To do so I refer to examples from some of my previous research projects and writings, which examine artists' and art teachers' relationships and interactions with art museums

Variations in attitude between children in different years towards peers with special physical needs in a Western Australian primary school

This study examined the attitudes of regular school students towards their peers with special needs within a Western Australian primary school. Comparisons were made between the children In Years 1, 4 and 7 of a specific school to identify whether any significant variations in attitude were present between the different years. Attitudinal data was collected by presenting an oral questionnaire to one, randomly selected, class of students from each of the three year group

Stability of continuously pumped atom lasers

A multimode model of a continuously pumped atom laser is shown to be unstable below a critical value of the scattering length. Above the critical scattering length, the atom laser reaches a steady state, the stability of which increases with pumping. Below this limit the laser does not reach a steady state. This instability results from the competition between gain and loss for the excited states of the lasing mode. It will determine a fundamental limit for the linewidth of an atom laser beam.Comment: 4 page

FAS Behavioral Survey of Traits: Screening for Effects of Prenatal Exposure to Alcohol

The FAS BeST was developed by parents and educators of children with Fetal Alcohol Syndrome rating behaviors characteristic of FASD including; easily influenced by others, difficulty learning from experience, appearing and declaring innocence even when confronted with evidence to the contrary, and experiencing difficulties in other domains. The FAS BeST differentiates between children with PEA, dysgenesis of the corpus callosum (DCC), and attention deficit hyperactivity disorder (ADHD; Porter & Andrews, 2004). The sample included 294 participants. Using the cutoff score suggested by Porter and Andrews (2004) the accuracy rates were 78% for FAS/E, 100% for controls, 85% for DCC, and 100% for ADHD. Reliability for the FASD BeST was established for all groups using split-half analysis. Criterion validity was verified using the Achenbach behavioral checklists (2002). A factor analysis indicated the FAS BeST denotes a general factor. The FAS BeST is a reliable and valid measure that is easily administered and scored. Children with PEA can be screened to determine whether further evaluation is warranted and differentiate between disorders with similar behaviors, enabling professionals to better serve the child and assist the care providers

Managing students' option choices with technology

This poster outlines the system which the Business School Undergraduate Programme has developed to manage the choice of options by students studying on its programmes. This involves the production of a networked computer package which presents students with the options available to them and leads them through the process of choosing their options on-line. The reasons for developing this system are outlined and the advantages which it has brought to the administration of large numbers of students are discussed

DNA and pacific commensal models : applications, construction, limitations, and future prospects

Components of the Pacific transported landscape have been used as proxies to trace the prehistoric movement of humans across the Pacific for almost two decades. Analyses of archaeological remains and DNA sequences of plants, animals, and microorganisms moved by or with humans have contributed to understanding prehistoric migration, trade, exchange, and sometimes revealed the geographic origins of particular plants and animals. This paper presents the basic elements of a DNA-based commensal model and discusses the phylogenetic and population genetic approaches these models employ. A clear delineation of the underlying assumptions of these models and the background information required to construct them have yet to appear in the literature. This not only provides a framework with which to construct a commensal model but also highlights gaps in current knowledge. The ways in which commensal models have enriched archaeological reconstructions will be highlighted, as will their current limitations. With these limitations in mind, options will be outlined for augmenting commensal models through the application of established techniques and new technologies in order to provide the best tools for reconstructing ancient human mobility and behavior in the Pacific and beyond

User-driven design of robot costume for child-robot interactions among children with cognitive impairment

The involvement of arts and psychology elements in robotics research for children with cognitive impairment is still limited. However, the combination of robots, arts, psychology and education in the development of robots could significantly contribute to the improvement of social interaction skills among children with cognitive impairment. In this article, we would like to share our work on building and innovating the costume of LUCA's robot, which incorporating the positive psychological perspectives and arts values for children with cognitive impairment. Our goals are (1) to educate arts students in secondary arts school on the importance of social robot appearance for children with cognitive impairment, and (2) to select the best costume for future child-robot interaction study with children with cognitive impairments
